PRESENTATION OF FINANCIAL INFORMATION

Preparation of Financial Statements in IFRS

Our consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (''IFRS'') as endorsed by the EU (''EU-IFRS''). EU-IFRS may differ from IFRS as issued by the International Accounting Standards Board (''IASB'') if, at any point in time, new or amended reporting standards have not been endorsed by the EU. As of December 31, 2011, 2010 and 2009, there were no unendorsed standards effective as of and for the years ended December 31, 2011, 2010 and 2009, respectively, that affected our consolidated financial statements, and there was no difference between EU-IFRS and IFRS as issued by the IASB as applied by Portugal Telecom. Accordingly, our financial statements as of and for the years ended December 31, 2011, 2010 and 2009 were prepared in accordance with IFRS as issued by the IASB. IFRS comprise the accounting standards issued by the IASB and its predecessor body and interpretations issued by the International Financial Reporting Interpretations Committee (''IFRIC'') and its predecessor body.

We publish our financial statements in Euro, the single EU currency adopted by certain participating member countries of the European Union, including Portugal, as of January 1, 1999. The Federal Reserve Bank of New York's noon buying rate in the City of New York for Euros was A0.7615 = US\$1.00 on April 19, 2012, and the noon buying rate on that date for Reais was R\$1.8846 = US\$1.00. We are not representing that the Euro, US\$ or R\$ amounts shown herein could have been or could be converted at any particular rate or at all. See ''Item 3—Key Information—Exchange Rates'' for further information regarding the rates of exchange between Euros and U.S. dollars and between Reais and U.S. dollars.

Proportional Consolidation of Brazilian Operations

On March 28, 2011, we completed the acquisition of an economic interest of 25.3% in Oi (through a 25.6% economic interest in TmarPart and a 25.3% interest in Telemar Norte Leste S.A.). Since April 1, 2011, given our economic interest and our rights to participate in the management of TmarPart and Oi as described in ''Item 4—Information on the Company—Brazilian Operations (Oi)—Strategic Partnership with Oi,'' we have proportionally consolidated 25.6% of TmarPart in our consolidated financial statements, which, in turn, fully consolidates TNL (which has now merged into Oi S.A.) and Telemar. Our economic interest in Oi decreased to 23.25% as a result of a corporate reorganization of

Oi that was completed on April 9, 2012. However, our economic interest in TmarPart remains at 25.6%, and we will continue to proportionally consolidate 25.6% of TmarPart in future periods.

Concurrently with our investment in Oi, we acquired a 16.2% economic interest in CTX Participa¸coes S.A. (''CTX''), the parent company of Contax Participa¸ ˜ coes S.A. (''Contax Participa¸ ˜ coes'') ˜ and Contax S.A. (''Contax''), which provides contact center, business process outsourcing (''BPO'') and IT services in Brazil and other countries in Latin America. Even before our investment in Contax, we provided call center and IT services in Brazil through our subsidiary Dedic, S.A. (''Dedic''), and Dedic's subsidiary GPTI—Tecnologias de Informa¸cao, S.A. (''GPTI'') provided Information Technology/ ˜ Information Systems (''IT/IS'') services in Brazil. On June 30, 2011, we merged Dedic and GPTI into Contax, and our economic interest in Contax increased to 19.5%. We have proportionally consolidated the results of operations of Contax in our results of operations since April 1, 2011, and Contax's results of operations have included the results of operations of Dedic and GPTI since July 1, 2011.

Discontinued Operations

We provided mobile telecommunications services in Brazil through Vivo Participa¸coes S.A. ˜ (''Vivo'') through September 2010. We held our participation in Vivo through our 50% interest in Brasilcel N.V., a joint venture with Telefonica, S.A. (''Telef ´ onica''). On July 28, 2010, we reached an ´ agreement with Telefonica for them to buy from us our 50% interest in Brasilcel N.V. We closed the ´ transaction on September 27, 2010. Our consolidated statements of income and cash flows present Vivo under the caption ''Discontinued Operations'' for all periods presented, and our consolidated balance sheet as of December 31, 2010 and thereafter no longer includes the assets and liabilities related to Vivo.

FORWARD-LOOKING STATEMENTS

This Form 20-F includes, and documents incorporated by reference herein and future public filings and oral and written statements by our management may include, statements that constitute ''forwardlooking statements'' within the meaning of the United States Private Securities Litigation Reform Act of 1995. These statements are based on the beliefs and assumptions of our management and on information available to management at the time such statements were made. Forward-looking statements include, but are not limited to: (a) information concerning possible or assumed future results of our operations, earnings, industry conditions, demand and pricing for our services and other aspects of our business under ''Item 4—Information on the Company,'' ''Item 5—Operating and Financial Review and Prospects'' and ''Item 11—Quantitative and Qualitative Disclosures About Market Risk''; and (b) statements that are preceded by, followed by or include the words ''believes,'' ''expects,'' ''anticipates,'' ''intends,'' ''is confident,'' ''plans,'' ''estimates,'' ''may,'' ''might,'' ''could,'' ''would,'' the negatives of such terms or similar expressions.

Forward-looking statements are not guarantees of performance. They involve risks, uncertainties and assumptions. Although we make such statements based on assumptions that we believe to be reasonable, there can be no assurance that actual results will not differ materially from our expectations. Many of the factors that will determine these results are beyond our ability to control or predict. We do not intend to review or revise any particular forward-looking statements referenced in this Form 20-F in light of future events or to provide reasons why actual results may differ. Investors are cautioned not to put undue reliance on any forward-looking statements.

Any of the following important factors, and any of those important factors described elsewhere in this or in other of our SEC filings, among other things, could cause our results to differ from any results that might be projected, forecasted or estimated by us in any such forward-looking statements:

• material adverse changes in economic conditions in Portugal, Brazil or the other countries in which we have operations and investments;

• the effects of intense competition in Portugal, Brazil and the other countries in which we have operations and investments;
• changes in telecommunications technology that could lead to obsolescence of our infrastruture;
• the development and marketing of new products and services and market acceptance of such products and services;
• risks and uncertainties related to national and supranational regulation; and
• the adverse determination of disputes under litigation.

Exchange Rates

Euro

The majority of our revenues, assets, liabilities and expenses are denominated in Euros. We have published our audited consolidated financial statements in Euros, and our shares trade in Euros on the regulated market Euronext Lisbon. Our financial results could be affected by exchange rate fluctuations in the Brazilian Real. See ''Item 5—Operating and Financial Review and Prospects—Exchange Rate Exposure to the Brazilian Real.''

Our dividends, when paid in cash, are denominated in Euros. As a result, exchange rate fluctuations have affected and will affect the U.S. dollar amounts received by holders of ADSs on conversion of such dividends by The Bank of New York, as the ADS depositary. The Bank of New York converts dividends it receives in foreign currency into U.S. dollars upon receipt, by sale or such other manner as it has determined and distributes such U.S. dollars to holders of ADSs, net of The Bank of New York's expenses of conversion, any applicable taxes and other governmental charges. Exchange rate fluctuations may also affect the U.S. dollar price of the ADSs on the New York Stock Exchange.

The following tables show, for the period and dates indicated, certain information regarding the U.S. dollar/Euro exchange rate. The information is based on the noon buying rate in the City of New York for cable transfers in Euro. On April 19, 2012, the Euro/U.S. dollar exchange rate was A0.7615 per US\$1.00.

Year ended December 31,	Average Rate(1)

2008	0.6805
2009	0.7166

(1) The average rate is calculated as the average of the noon buying rates on the last day of each month during the period.

None of the 27 member countries of the European Union has imposed any exchange controls on the Euro.

Brazilian Real

Although as of December 31, 2011, the majority of our revenues, assets and expenses are denominated in Euros, on March 28, 2011, we completed the acquisition of an economic interest of 25.3% in Oi. Oi records its financial position and results of operations in Brazilian Reais. Concurrently with our investment in Oi, we acquired an interest in Contax, which similarly records its financial

position and results of operations in Brazilian Reais. Consequently, exchange rate fluctuations between the Euro and the Brazilian Real affect our revenues, expenses, assets and liabilities.

The Brazilian government may impose temporary restrictions on the conversion of Reais into foreign currencies and on the remittance to foreign investors of proceeds from their investments in Brazil. Brazilian law permits the government to impose these restrictions whenever there is a serious imbalance in Brazil's balance of payments or reason to foresee a serious imbalance.

Risk Factors

General Risks Relating to Our Company

The current economic and financial crisis has affected, and will likely continue to affect, demand for our products and services, our revenues and our profitability

The global economic and financial crisis, and the current economic recession in Portugal, have had, and are likely to continue to have, an adverse effect on the demand for our products and services and on our revenues and profitability. The year ended December 31, 2011 was a turbulent year in the global markets, dominated by the continuing eurozone debt crisis that began with the global financial crisis in 2007 and, by 2011, had developed into a severe sovereign debt crisis. During 2011, a number of eurozone countries came under severe financial pressure and their ability to raise, refinance and service their debt was put into question by markets, as demonstrated by the record high spreads during most of the year. Portugal, along with Greece and Ireland, was forced to seek support packages from the European Central Bank (''ECB'') and the International Monetary Fund (''IMF'') under strict conditions, while fear of contagion to other eurozone countries forced governments to reduce debt levels through austerity measures that, at least in the short term, were seen as the cause of slow growth for some countries and stagnation in others.

On April 6, 2011, Portugal announced that it would seek an economic rescue package from the European Union. In the following months, Portugal formally requested an economic rescue package from the European Union and the International Monetary Fund and negotiated the terms of that package. As a condition to receiving the economic rescue package, the Portuguese government implemented severe budget-cutting measures that have delayed Portugal's emergence from a recession and weakened consumer demand.

Despite a number of high profile summits and meetings the EU was unable to agree and implement a strong coherent policy response to the crisis, prompting fear of default or the exit from the euro of one or more members. Under pressure during most of 2011, EU members showed an increasing willingness to agree a structured common approach, but they also demonstrated divergent opinions on the way forward and on the measures to be taken. This resulted in the three major rating agencies either downgrading, or putting on the watch list for possible downgrade, a number of sovereign governments which intensified the pressure, even on the stronger eurozone countries. The ongoing sovereign debt crisis, slow economic growth, dearth of market financing for banks and private sector deleveraging severely affected the eurozone financial system, increasing the possibility of further economic stress in the region, including Portugal.

Against the backdrop of the eurozone crisis, the increased risk perception also led to consecutive downgrades of Portuguese sovereign debt by the rating agencies. In 2011, Portugal was downgraded (1) by 4 notches at Moody's, from A1 on December 21, 2010 to Ba2 on July 5, 2011; (2) by 3 notches at S&P from A on November 30, 2011 to BBB on December 5, 2011, and (3) by 6 notches at Fitch from A+ on December 23, 2010 to BB+ on November 24, 2011.

As one of Portugal's largest companies and one of its largest employers (and although a large portion of our business is conducted outside Portugal), Portugal Telecom's financial condition, revenues and profitability are closely linked to circumstances in the Portuguese economy. The recession in Portugal has had a direct effect on demand for our products and services, contributing to a decline in revenues in 2011 across most of the customer categories of our Portuguese telecommunications business.

In these and other ways, the global economic and financial crisis and its effect on the European and Portuguese economies has significantly affected, and could continue to significantly affect, our business, liquidity and financial performance.

Financial market conditions may adversely affect our ability to obtain financing, significantly increase our cost of debt and negatively impact the fair value of our assets and liabilities

Beginning in 2008, events in the global and European financial markets have increased the uncertainty and volatility of the financial markets, leading to a significant increase in execution and price risks in financing activities. Since the onset of the crisis, global financial markets and economic conditions have been severely disrupted and volatile and remain subject to significant vulnerabilities, such as the deterioration of fiscal balances and the rapid accumulation of public debt, continued deleveraging in the banking sector and limited supply of credit. At times during this period, credit markets and the debt and equity capital markets have been exceedingly distressed. In 2010 and 2011, the financial markets grew increasingly concerned about the ability of certain European countries, particularly Greece, Ireland and Portugal, but also others such as Spain and Italy, to finance their deficits and service growing debt burdens amidst difficult economic conditions. This loss of confidence has led to rescue measures for Greece, Ireland and Portugal by the EU and the IMF. These issues, along with the re-pricing of credit risk and the difficulties currently experienced by financial institutions, have made it difficult for companies to obtain financing, and we expect these difficulties to continue.

As a result of the disruptions in the credit markets, many lenders have increased interest rates, enacted tighter lending standards, required more restrictive terms (including higher collateral ratios for advances, shorter maturities and smaller loan amounts) or refused to refinance existing debt at all or on terms similar to pre-crisis conditions. Changes in interest rates and exchange rates may also adversely affect the fair value of our assets and liabilities. If there is a negative impact on the fair values of our assets and liabilities, we could be required to record impairment charges.

Notwithstanding our international exposure and diversification and the fact that we believe we have liquidity to repay our debt through the end of 2013, the downgrades of Portugal's sovereign debt described in the preceding risk factor may have a significant effect on our costs of financing, particularly given the size and prominence of our company within the Portuguese economy. The recent events in Portugal and the other factors described above could adversely affect our ability to obtain future financing to fund our operations and capital needs and adversely impact the pricing terms that we are able to obtain in any new bank financing or issuance of debt securities and thereby negatively impact our liquidity.

Any future ratings downgrades may impair our ability to obtain financing and may significantly increase our cost of debt

The effects of the economic and financial crisis described above, or any adverse developments in our business, could lead to downgrades in our credit ratings. Any such downgrades are likely to adversely affect our ability to obtain future financing to fund our operations and capital needs. Any downgrade of our ratings could have even more significant effects on our ability to obtain financing and therefore on our liquidity. For example, the pricing conditions applicable to our commercial paper programs could be revised in the event our credit rating is changed. In addition, certain of our loan agreements, totaling A129 million as of December 31, 2011, contain provisions that require us to provide certain guarantees if our ratings decline below specified levels. Any failure to provide those guarantees could enable the lender to accelerate the loans. For further information on these covenants, please refer to ''Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Indebtedness—Covenants.''

Any worsening of the current economic and financial crisis may affect our liquidity and impact the creditworthiness of our company

In order to mitigate liquidity risks, we seek to maintain a liquidity position and an average maturity of debt that allows us to repay our short-term debt and our contractual obligations. As of December 31, 2011, the amount of available cash from our Portuguese operations (excluding cash from our international operations), plus the undrawn amount of our underwritten commercial paper lines (cash immediately available upon two or three days' notice) and our committed standby facilities available to our Portuguese operations amounted to A5,095 million, a reduction from A6,297 million as of December 31, 2010. This reduction reflects primarily the investments made in the acquisition of the interests in Oi and Contax and dividends paid during the year, which more than offset the impact of the third and last installment payment received from Telefonica for its purchase of Vivo and certain ´ new financings obtained in 2011. The average maturity of our net debt in Portugal as of December 31, 2011 was 5.9 years.

We seek to manage our capital structure to ensure that our businesses will be able to continue as a going concern and maximize the return to shareholders. Our capital structure includes debt, cash and cash equivalents, short-term investments and equity attributable to equity holders of the parent, comprising issued capital, treasury shares, reserves and accumulated earnings. We periodically review our capital structure considering the risks associated with each of the above mentioned classes of the capital structure. We further discuss our liquidity and sources of funding in ''Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources.''

However, if economic and financial conditions in Portugal and in Europe generally were to worsen, if our cost of debt were to increase or if we were to encounter other difficulties in obtaining financing for the reasons described in the preceding three risk factors, our sources of funding, including our cash balances, operating cash inflows, funds from divestments, credit lines and cash flows obtained from financing operations, might not match our financing needs, including our operating and financing outflows, investments, shareholder remuneration and debt repayments. Any such event could have a material adverse effect on our financial position, liquidity and prospects.

If our customers' financial conditions decline, we will be exposed to increased credit and commercial risks

Due to continued adverse economic conditions, we may encounter increased difficulty collecting accounts receivable and could be exposed to risks associated with uncollectable accounts receivable. We regularly assess the creditworthiness of our customers and we set credit limits for our customers. Challenging economic conditions have impacted some of our customers' ability to pay their accounts receivable. Although our credit losses have historically been low and we have policies and procedures for managing customer finance credit risk, we may be unable to avoid future losses on our accounts receivable, which could materially adversely affect our results of operations and financial position.

We may not be able to pay our announced dividends

In connection with the sale of our interest in Vivo in September 2010, we announced an extraordinary dividend to our shareholders of A1.65 per share, of which we paid A1.00 per share on December 28, 2010. As approved at our General Shareholders' Meeting held on May 6, 2011, we paid the remaining A0.65 per share of this dividend, as well as an ordinary dividend of A0.65 per share with respect to the year ended December 31, 2010 on June 3, 2011. In 2011, we adopted a progressive dividend policy with the objective of raising the dividend per share every year between 3% and 5% for the period between 2012 and 2014. In addition, for the year ended December 31, 2011 onwards, we announced that our Board of Directors intended to approve the payment of interim ordinary dividends based on the financial performance of our company in order to allow for a smoother cash return to our shareholders throughout the year. As a result, on December 15, 2011, our Board of Directors announced an interim dividend of A0.215 per share, which was paid on January 4, 2012. This dividend was an advance payment on the profits of the year ended December 31, 2011 for our shareholders. On March 30, 2012, the Board of Directors announced a proposal approved at the General Shareholder's Meeting held on April 27, 2012 of a dividend of A0.65 per share, including the above-mentioned A0.215 dividend paid in January 2012. These cash dividend proposals are subject to market conditions, our financial condition, applicable law regarding the distribution of net income, including additional shareholder approvals, and other factors considered relevant by our Board of Directors at the time.

The payment of future dividends will depend on our ability to continue to generate cash flow in our businesses, which is dependent not only on our revenue stream but also on our ability to further streamline our operations and reduce our costs. In addition, significant volatility in the Real/Euro exchange rate may impair our ability to pay dividends.

If any of the conditions described above proves not to be the case or if any other circumstances (including any risks described in this ''Risk Factors'' section) impede our ability to generate cash and distributable reserves, shareholders may not receive the full remuneration we have announced, and the price of our ordinary shares and ADSs could be negatively affected.

We must continue to attract and retain highly qualified employees to remain competitive

We believe that our future success largely depends on our continued ability to hire, develop, motivate and retain qualified personnel needed to develop successful new products, support our existing product range and provide services to our customers. Competition for skilled personnel and highly qualified managers in the telecommunications industry remains intense. We are continuously developing our corporate culture, remuneration, promotion and benefits policies as well as other measures aimed at empowering our employees and reducing employee turnover. However, we may not be successful in attracting and retaining employees with appropriate skills in the future, and failure in retention and recruiting could have a material adverse effect on our business.

Unfunded post retirement benefit obligations may put us at a disadvantage to our competitors and could adversely affect our financial performance

We have unfunded post retirement benefit obligations that may limit our future use and availability of capital and adversely affect our financial and operating results. Although in December 2010, we transferred to the Portuguese Government the post retirement benefits obligations relating to regulated pensions of Caixa Geral de Aposenta¸coes and Marconi, we retained all other obligations, including ˜ (1) salaries to suspended and pre-retired employees amounting to A782.5 million as of December 31, 2011, which we must pay monthly directly to the beneficiaries until their retirement age and (2) A474.1 million in obligations related to pension supplements and healthcare as of December 31, 2011, which are backed by plan assets with a market value of A344.7 million, resulting in unfunded obligations of A129.4 million.

Any decrease in the market value of our plan assets relating to our pension supplements and healthcare obligations could increase our unfunded position. Although there is in place an investment policy with capital preservation targets, in the current economic and financial crisis, in particular, the market value of our plan assets is volatile and poses a risk. In addition, our obligations to pay salaries to suspended and pre-retired employees are unfunded. The value of the obligations referred to above may also fluctuate, depending on demographic, financial, legal or regulatory factors that are beyond our control. Any significant increase in our unfunded obligations could adversely affect our ability to raise capital, require us to use cash flows that we would otherwise use for capital investments, implementing our strategy or other purposes and adversely affect perceptions of our overall financial strength, which could negatively affect the price of our ordinary shares and ADSs.

See ''Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Post Retirement Obligations'' for a description of our transfer of pension obligations to the Portuguese Government.

Risks Relating to Our Portuguese Operations

Competition from other mobile telephony and fixed line operators has reduced our revenues from our Portugese operations and could continue to adversely affect our revenues

As a result of the trend toward the use of mobile services instead of fixed telephone services, combined with the increase in competition from other operators, we have experienced, and may continue to experience, erosion of market share of both access lines and of outgoing domestic and international traffic. The number of active mobile telephone cards in Portugal has overtaken the number of wireline main lines. Mobile operators can bypass our international wireline network by interconnecting directly with fixed line and mobile networks either in our domestic network or abroad. Competition is also forcing down the prices of our fixed line voice services for long distance and international calls. Lowering our international call prices has caused a decline in our revenues from international fixed line voice services. The decrease in fixed line voice traffic and lower tariffs resulting from competition has significantly affected our overall revenues, and we expect these factors to continue to negatively affect our revenues. See ''Item 4—Information on the Company—Competition— Competition Facing Our Portuguese Operations—Residential Services.''

Increased competition in the Portuguese Pay-TV market may result in a decrease in our revenues

In 2008, we launched a nationwide Pay-TV service under the Meo brand, primarily using our fixed network (IPTV over ADSL2+ and fiber-to-the-home (''FTTH'') and direct-to-home (''DTH'') satellite technology). This service required us to make significant investments in our network in order to increase the bandwidth and offer a better service quality than our competitors. The main competitors in the market are Zon, Cabovisao, Optimus and Vodafone. Notwithstanding gains in our revenues and ˜ market share from Pay-TV services in recent years and the quality of our service, we have experienced pressure from our competitors to reduce monthly subscription fees. In addition, our efforts to build scale to enable us to negotiate better programming costs with our content suppliers, especially certain premium content owned by one of our competitors, may not prove successful. Our revenues from residential services and our financial position could be significantly affected if we are not successful in the Pay-TV business, which is becoming increasingly important as a retention tool of our fixed-line and broadband customers.

The broadband market in Portugal is highly competitive and may become more competitive in the future

Our competitors have been improving their commercial offers in broadband Internet, with most of them offering triple-play bundled packages (voice telephony, broadband Internet and Pay-TV subscription). We believe that with competition in Internet broadband access intensifying, and with the development of existing technologies such as broadband wireless access, mobile broadband through Universal Moblie Telecommunications System (''UMTS'') and long-term evolution (''LTE'') technology, as well as high speed broadband supported by the deployment of a fiber optic network, we may face additional pricing pressure on our services, which could result in the loss of revenues from both residential and enterprise customers.

Increased competition in the Portuguese mobile markets may result in decreased tariffs and loss of market share

We operate in the highly competitive Portuguese mobile telecommunications market. We believe that our existing mobile competitors, Vodafone and Optimus, will continue to market their services aggressively, and in most cases, those operators have similarly priced offers. After we launched our low-cost brand ''Uzo,'' for example, Vodafone and Optimus quickly responded with similar products of their own. As another example, in 2010, we launched a tribal plan as a reaction to similar plans launched by our competitors, and that plan provides for lower revenue per user than many of our other plans. We believe that our ability to compete depends on our ability to differentiate our products based on services offered and quality, and we may not be successful in doing so.

We expect competition from VoIP-based operators also to place increasing price pressure on voice tariffs and lead to reductions in mobile voice traffic. Competition from companies providing wireless local-area network services (''WLAN''), which can deliver wireless data services more cheaply than mobile data services, such as through UMTS or LTE technology, in concentrated areas, may also affect the market and pricing for third and fourth generation services. See ''Item 4—Information on the Company—Competition—Competition Facing Our Portuguese Operations—Personal Services.''

Our ability to remain competitive depends on our ability to implement new technology, and any failure to do so could adversely affect our business

Companies in the telecommunications industry must adapt to rapid and significant technological changes that are usually difficult to anticipate. The Pay-TV, broadband internet and mobile telecommunications industries in particular have experienced rapid and significant technological development and frequent improvements in capacity, quality and data-transmission speed. Technological changes may render our equipment, services and technology obsolete or inefficient, which may

adversely affect our competitiveness or require us to increase our capital expenditures in order to maintain our competitive position. For example, we have made significant investments in recent years to develop our FTTH network for residential and enterprise customers, to connect our mobile network base stations and to develop our UMTS network for personal services customers. In 2011, we also upgraded some of our mobile network equipments for LTE services. We are investing significant amounts to construct our data center in Covilha, Portugal to expand our ability to serve enterprise and ˜ other customers, and we launched LTE services in March 2012. We may not achieve the expected benefits of these investments in technology before more advanced technology is adopted by the market. Even if we adopt new technologies in a timely manner as they are developed, the cost of such technology may exceed the benefit to us, and we cannot assure you that we will be able to maintain our level of competitiveness.

Burdensome regulation in an open market may put us at a disadvantage to our competitors and could adversely affect our Portugese telecommunications business

The Portuguese electronic communications sector is fully open to competition. However, many regulatory restrictions and obligations are still imposed on us. In the previous round of market analysis, carried out in 2004-2006, Portugal Telecom was found by the Portuguese telecomunications regulator (Autoridade Nacional das Comunica¸coes ˜ —''ANACOM'') to have significant market power in all but one of the 16 markets analyzed and, consequently, is subject to regulatory restrictions and obligations. Not all of these obligations and restrictions have been imposed on other telecommunications operators and service providers. Pursuant to the European Relevant Markets Recommendation issued in 2007, which significantly reduced the number of markets subject to regulation, ANACOM is re-analyzing the retail and wholesale markets to identify which electronic communications operators and service providers it considers to have significant market power in those markets and determining the regulatory obligations that should be imposed on those operators and service providers.

ANACOM has re-analyzed certain of the markets defined under the European Relevant Market Recommendation and has found Portugal Telecom to have significant market power in some of those markets, including the wholesale market for call termination on individual public telephone networks provided at a fixed location, the market for call termination on individual mobile networks, the market for the provision of wholesale (physical) network infrastructure access and the wholesale leased lines terminal market. In certain cases, such as the wholesale broadband access market and the wholesale transit market, ANACOM has segmented the markets into ''C'' (competitive) and ''NC'' (noncompetitive) segments and has found Portugal Telecom to have significant market power in the non-competitive segments. ANACOM has the power to impose remedies to increase competition in those markets. For example, ANACOM is proposing to introduce virtual access to fiber (an advanced bitstream offer) as a remedy in the wholesale (physical) network infrastructure access market in certain geographic areas. In addition, ANACOM has not completed its analysis of all the markets identified by the European Relevant Market Recommendation, and we expect that it will provide further analysis in the near future.

Remedies imposed by ANACOM may require us to provide services in certain markets or geographic regions or to make investments that we would otherwise not choose to make. In addition, we incur expenses to adapt our operations to constantly changing regulatory requirements and to ensure regulatory compliance. The substantial resources we must commit to fulfill our regulatory obligations could adversely affect our ability to compete. See ''Item 4—Information on the Company— Regulation—Portugal'' for more details on the regulatory requirements to which we are subject.

Reduced interconnection rates have negatively affected our revenues for our Portuguese telecommunications business and will continue to do so in 2012

In recent years, ANACOM has imposed price controls on interconnection rates for the termination of calls on mobile networks. These reductions have had a significant impact on interconnection revenues of our mobile subsidiary, TMN—Telecomunica¸coes M ˜ oveis Nacionais, S.A. (''TMN''), and, ´ consequently, on its earnings.

In April 2011, ANACOM held a consultation on the definition of a bottom-up long-run incremental cost (''LRIC'') model to regulate mobile termination rates. In October 2011, ANACOM issued a new draft decision based on that cost model and proposed a new glide path according to which mobile termination rates in Portugal would decrease in four steps, reaching A0.0125 per minute by November 2012. In March 2012, ANACOM issued a final decision reducing mobile termination rates progressively to A0.0127 by December 2012. The reductions in mobile termination rates have had and will continue to have a negative effect on our cash flows and revenues.

ANACOM's price controls on fixed-to-mobile interconnection may also negatively affect our revenues from fixed line residential services because we are required to reflect the reduction in these interconnection charges in our retail prices for calls from our fixed line network. We expect that the reduction in interconnection charges will continue to have an impact on our revenues from fixed line residential services.

In addition, the lower interconnection rates have reduced revenues for our wholesale business, which records revenue from incoming calls transiting through our network that terminate on the networks of mobile operators. The prices we charge to international operators (and hence our revenues) also depend on the interconnection fees charged by mobile operators for international incoming calls terminating on their networks, and these fees have been decreasing. We expect that lower interconnection rates will continue to have a negative impact on our wholesale revenues.

In addition, in August 2008, ANACOM published a ''reasoning'' regarding mobile rates for originating calls, aimed at driving mobile operators to reducing their prices by the end of September 2008 to a level equal or close to the level of mobile termination rates. In the second half of 2008, the three mobile operators reduced their rates for originating calls but not to the extent desired by ANACOM. In February 2010, ANACOM chose to take the matter to the Portuguese national competition authority (the ''Autoridade da Concorrencia'' or ''AdC''). In January 2012, the Autoridade ˆ da Concorrencia completed its analysis, finding origination rates to be excessive and stating that mobile ˆ operators must reduce their rates to the level of their costs by July 2012 or face the possibility of being sanctioned.

The European Commission's review of roaming charges may lead to a reduction in revenues from personal services

The European Commission has determined that roaming prices in Europe should be reduced and has published new regulations that have been in effect since 2007. These regulations set maximum roaming charges that may be charged in the wholesale market and the retail market. In 2008, the European Commission launched a consultation on roaming, proposing to carry over Regulation (EC) No. 717/2007, on roaming on mobile communications networks within the community (the ''Roaming Regulation''), beyond 2010 and to extend it to data and Short Messaging Services (''SMS''), or text messaging. In 2009, Regulation (EC) No. 544/2009, amending the Roaming Regulation (the ''New Roaming Regulation''), went into effect, limiting roaming charges. The New Roaming Regulation aimed to reduce roaming charges by up to 60%. In the wholesale market, a maximum roaming charge of A0.18 per minute currently applies. In the retail market, maximum roaming charges of A0.11 per minute (for received calls) and A0.35 per minute (for outgoing calls) currently apply.

The New Roaming Regulation is due to expire on June 30, 2012 and to be replaced by a third version, known as ''Roaming III.'' The European Commission has proposed revisions to certain of those standards, including (1) a cap on retail data tariffs, proposed for July 2012, (2) introduction of an obligation for mobile operators to provide network access in order to allow roaming services, proposed for July 2012, and (3) the decoupling of roaming services from other services, while enabling a consumer to use the same number, proposed for July 2014. We expect the European Commission to make a final decision on these proposals in May 2012.

The New Roaming Regulation has had, and we expect Roaming III to have, an adverse effect on the revenues of our mobile business and on our results of operations.

The Portuguese government could terminate or fail to renew our fixed line concession, our licenses and our authorizations for data and mobile services

We provide a significant number of services under a concession granted to us by the Portuguese government and under licenses and authorizations granted to us by ANACOM. See ''Item 4— Information on the Company—Regulation—Portugal—Summary of Our Concession and Existing Licenses and Authorizations.'' The Portuguese government can revoke our concession if it considers the revocation to be in the public interest. It can also terminate our concession at any time if we fail to comply with our obligations under the concession.

Our concession and Portuguese law impose obligations on us as a universal services provider. See ''Item 4—Information on the Company—Regulation—Portugal—Universal Services Obligations.'' ANACOM recently completed a public consultation on the process for selecting a universal services provider and issued a final decision in February 2012, dividing universal services by three functions (telephone service, pay telephones, and directory and inquiry services) and further in three geographic regions. On April 12, 2012, the government launched a public consultation on proposed legislation to establish a compensation fund for universal service providers, after which the Portuguese government is expected shortly thereafter in 2012 to launch a tender for the designation of the universal service providers. The designation of the universal service providers and related renegotiation of our concession are explicit objectives set forth in the memorandum of understanding entered into by the Portuguese government, the IMF, the European Commission and the European Central Bank in the context of the financial support package provided to Portugal. Our rights and obligations as a universal service provider could be materially affected by the tender process, pursuant to which we could cease to be the universal service provider for certain services or in certain regions.

The Portuguese government can also terminate our mobile licenses under certain circumstances. Through TMN, we hold renewable license to provide GSM and UMTS mobile telephone services throughout Portugal, valid until 2016 and 2022, respectively. In January 2012, TMN was allocated the right to use frequencies to provide, among other technologies, LTE mobile telephone services throughout Portugal, and in March 2012, ANACOM issued a renewable licence to TMN, valid until 2027, with respect to the use of these frequencies. This license also unifies the previous GSM and UMTS licenses issued to TMN. If the Portuguese government were to terminate our license, we would not be able to conduct the activities authorized by the concession or the relevant licenses. This loss would eliminate an important source of our revenues.

Regulatory investigations and litigation may lead to fines or other penalties

We are regularly involved in litigation, regulatory inquiries and investigations involving our operations. ANACOM, the European Commission and the Autoridade da Concorrencia regularly make ˆ inquiries and conduct investigations concerning our compliance with applicable laws and regulations. Current inquires by the Autoridade da Concorrencia relate to alleged anti-competitive practices in the ˆ broadband internet, terrestrial television and public mobile telephone markets.

In addition, on January 19, 2011, the European Commission opened an investigation into an agreement between Telefonica and Portugal Telecom allegedly not to compete in the Iberian ´ telecommunications markets. Portugal Telecom has developed various strategic partnerships with Telefonica in recent years. Although we do not believe the existence of these partnerships has impeded ´ competition and ordinary activities of our company and Telefonica, our relationship with Telef ´ onica is ´ now subject to investigation. The European Commission has stated that the initiation of proceedings does not imply that the Commission has conclusive proof of an infringement but that the Commission will deal with the case as a matter of priority. On October 25, 2011, we were notified of a Statement of Objections sent by the European Commission to us and Telefonica on the matter. The Statement of Objections only covers alleged cooperation between the two companies after the Vivo transaction. In response to the Statement of Objections, we contested the allegations of the European Commission. The sending of a Statement of Objections does not prejudge the final outcome of the investigation. We cannot predict whether this investigation may lead to fines or other sanctions or whether it may have an adverse effect on our business.

These inquiries and investigations are described in ''Item 8—Financial Information—Legal Proceedings.'' If we are found to be in violation of applicable laws and regulations in these or other regulatory inquiries, investigations, or litigation proceedings that are currently pending against us or that may be brought against us in the future, we may become subject to penalties, fines, damages or other sanctions. Any adverse outcome could have a material adverse effect on our operating results or cash flows.

Risks Related to Our Brazilian Operations

Our strategy of enhancing our operations in Brazil through our strategic partnerships with Oi and Contax may not be successful, and we do not have free access to cash flows from Oi and Contax

The successful implementation of our strategy for our mobile operations in Brazil depends on the development of our strategic partnership with Oi. On March 28, 2011, we completed the acquisition of a 25.3% economic interest in the Oi companies. For the year ended December 31, 2011, 47% of our revenues were generated in Brazil, and our strategic partnership with Oi represented the bulk of these revenues. As in any strategic partnership, it is possible that we, the other controlling shareholders and Oi will not agree on its strategy, operations or other matters. Any inability of Oi and us to operate Oi jointly could have a negative impact on Oi's operations, which could have a negative impact on our strategy in Brazil and could have a material adverse effect on our results of operations. In addition, we cannot be sure that Oi will be able to take advantage of its position in the Brazilian market to increase the scope and scale of its operations or that any anticipated benefits of the strategic partnership will be realized.

In addition, concurrently with our investment in Oi, we acquired a 16.2% economic interest in Contax, which provides among other contact center services in Brazil. Our economic interest in Contax increased to 19.5% in June 2011. Although the contribution of Contax to our consolidated revenues is not as significant as that of Oi, Contax remains an important part of our international telecommunications business. The types of risks described above that apply to our strategic partnership with Oi also apply to our strategic partnership with Contax.

In addition, because we hold joint control of Oi and Contax, we may not have free access to their cash flows. It will be necessary for us and other controlling shareholders of Oi and Contax to agree to approve any distributions from those companies. See ''Item 4—Information on the Company—Our Businesses—Brazilian Operations (Oi)—Strategic Partnership with Oi'' and ''Item 4—Information on the Company—Our Businesses—Other International Operations—Other Brazilian Operations—Strategic Partnership with Contax.''

We are exposed to Brazilian exchange rate and interest rate fluctuations

We are exposed to exchange rate fluctuation risks, mainly due to our significant investments in Brazil. On March 28, 2011, we completed the acquisition of an economic interest of 25.3% in Oi (through a 25.6% economic interest in TmarPart and a 25.3% interest in Telemar Norte Leste S.A.), Brazil's largest telecommunications group. We do not expect to hedge our economic exposure against exchange rate fluctuations. We are required to make adjustments to our equity on our balance sheet in response to fluctuations in the value of foreign currencies in which we have made investments. Devaluation of the Brazilian Real in the future could result in negative adjustments to our balance sheet, which could limit our ability to generate distributable reserves.

We are also exposed to interest rate fluctuation risks. We have entered into financial instruments to reduce the impact on our earnings of an increase in market interest rates, but these financial instruments may not prevent unexpected and material fluctuations of interest rates from having any material adverse effect on our earnings.

The Brazilian Central Bank's Monetary Policy Committee (Comitˆe de Pol´ıtica Monetaria do Banco ´ Central—COPOM) establishes the basic interest rate target for the Brazilian financial system by referring to the level of economic growth of the Brazilian economy, the level of inflation and other economic indicators. As of December 31, 2007, 2008, 2009, 2010 and 2011, the basic interest rate was 11.3%, 13.8%, 8.8%, 10.8% and 11%, respectively. Increases in interest rates may have a material adverse effect on Oi by increasing its interest expense on floating rate debt and increasing its financing costs.

Macroeconomic factors in Brazil could reduce expected returns on our Brazilian investments

A material portion of our business, prospects, financial condition and results of operations has been, and will continue to be, dependent on general economic conditions in Brazil. In particular, our growth depends on economic growth and its impact on demand for telecommunications and other related services. The major factors that could have a material adverse effect on our investments and results of operations in Brazil include:

Adverse political and economic conditions. The Brazilian government has exercised, and continues to exercise, significant influence over the Brazilian economy. The Brazilian government has utilized salary and price controls, currency devaluation, capital controls and limits on imports, among other things, as tools in its previous attempts to stabilize the Brazilian economy and control inflation. Changes in the Brazilian government's exchange control policy, or in general economic conditions in Brazil, could have a material adverse effect on the results of our operations in Brazil. Deterioration in economic and market conditions in other countries (mainly in other Latin American and emerging market countries) may adversely affect the Brazilian economy and our business.

Past political crises in Brazil have affected the confidence of investors and the public in general, as well as the development of the economy. Any future political crises could have an adverse impact on the Brazilian economy and on our business, financial condition and results of operations in Brazil.

Fluctuations in the Real and increases in interest rates. The Brazilian currency has historically experienced frequent fluctuations relative to the Euro and other currencies. In 2007, 2009 and 2010, the Real appreciated against the Euro by 8.3%, 29.2% and 13.2%, respectively, and in 2008 and 2011 the Real depreciated against the Euro by 20.0% and 8.5%, respectively. Any substantial negative reaction to the policies of the Brazilian government could have a negative impact, including devaluation. The devaluation of the Real could negatively affect the stability of the Brazilian economy and accordingly could negatively affect the profitability and results of our operations and our ability to distribute reserves. It would also increase costs associated with financing our operations in Brazil. In particular, a significant amount of Oi's financial liabilities are denominated in or indexed to foreign

currencies, primarily U.S. dollars, Japanese yen and euros. When the Real depreciates against foreign currencies, Oi incurs losses on its liabilities denominated in or indexed to foreign currencies, such as its U.S. dollar-denominated long-term debt and foreign currency loans, and it incurs gains on its monetary assets denominated in or indexed to foreign currencies, as the liabilities and assets are translated into Real. If significant depreciation of the Real were to occur when the value of such liabilities significantly exceeds the value of such assets, including any financial instruments entered into for hedging purposes, Oi could incur significant losses, even if the value of those assets and liabilities has not changed in their original currency. In addition, a significant depreciation in the Real could adversely affect Oi's ability to meet certain of our payment obligations. A failure to meet certain of Oi's payment obligations could trigger a default under certain financial covenants in its debt instruments, which could have a material adverse effect on Oi's business and results of operations. Additionally, Oi currently has currency swaps and non-deliverable forwards in place for a portion of its foreign currency debt. However, if the cost of currency swap instruments increases substantially, Oi may be unable to maintain its hedge positions, resulting in an increased foreign currency exposure, which could in turn lead to substantial foreign exchange losses.

In addition, a devaluation of the Real relative to the U.S. dollar may increase the costs of imported products and equipment. Our operations in Brazil rely on imported equipment, and, as a result of such devaluation, such equipment would be more expensive to purchase.

In response to the global economic and financial crisis, the Brazilian government increased the SELIC basic interest rate to 13.75% as of December 31, 2008. In 2009, Brazilian Central Bank reduced the SELIC rate to 8.75% as of December 31, 2009. Based on further economic developments, the Brazilian Central Bank increased the SELIC rate up to 10.75% as of December 31, 2010 and to 11% as of December 31, 2011. Most recently, the Brazilian Central Bank reduced the SELIC rate to 10.50% as of January 18, 2012 and to 9.00% as of April 18, 2012. However, Brazilian interest rates remain high, and any increase in interest rates could negatively affect our profitability and results of operations and would increase the costs associated with financing our operations in Brazil.

Inflation in Brazil. Brazil has historically experienced high rates of inflation. Inflation, as well as governmental measures put in place to combat inflation, have had a material adverse effect on the Brazilian economy. Inflationary pressures persist, and actions taken in an effort to curb inflation, coupled with public speculation about possible future governmental actions, have in the past contributed to economic uncertainty in Brazil and heightened volatility in the Brazilian securities market. According to the Broad Consumer Price Index (´Indice Nacional de Pre¸cos ao Consumidor Amplo, or ''IPCA''), published by the Brazilian Institute for Geography and Statistics (Instituto Brasileiro de Geografia e Estat´ıstica , or ''IBGE''), the Brazilian consumer price inflation rates were 4.5% in 2007, 5.9% in 2008, 4.3% in 2009, 5.9% in 2010 and 6.5% in 2011.

Since 2006, Oi's telephone rates have been indexed to the Telecommunications Service Index (´Indice de Servi¸cos de Telecomunica¸coes ˜ , or ''IST''), which is a basket of national indexes that reflect the Brazilian telecommunications sector's operating costs. However, Brazilian monetary policy continues to use the IPCA as an inflation targeting system. The inflation target for 2012 is 4.5%. In recent years, Brazil has failed to meet its inflation target. According to the Brazilian monetary authority, the official inflation target was only met in one calendar year over the past three years. In 2009, the official target inflation rate of 4.50% was 4% higher than the actual inflation rate of 4.32%. However, in 2010 and 2011, Brazil's actual inflation rate was 5.91% and 6.50%, respectively, 31.3% and 44.4% higher than the 4.50% inflation target set for both calendar years. If inflation increases beyond the official 2012 target, basic interest rates may rise, causing direct effects on Oi's cost of debt and indirect effects on the demand for telecommunications goods and services. These effects are aggravated by the uncertainties historically observed in Brazil's economy.

If Brazil experiences substantial inflation in the future, Oi's costs may increase and its margins may decrease. Although ANATEL regulations provide for annual price increases for most of Oi's services, these increases are linked to inflation indices, as described above, discounted by increases in our productivity. During periods of rapid increases in inflation, the price increases for Oi's services may not be sufficient to cover its additional costs, and Oi may be adversely affected by the lag in time between the incurrence of increased costs and the receipt of revenues resulting from the annual price increases.

Restrictions on the movement of capital out of Brazil. Brazilian law provides that whenever there exists, or there is a serious risk of, a material imbalance in Brazil's balance of payments, the Brazilian government may impose restrictions for a limited period of time on the remittance to foreign investors of the proceeds of their investments in Brazil as well as on the conversion of the Real into foreign currencies. The Brazilian government imposed such a restriction on remittances for approximately six months in 1989 and early 1990. The Brazilian government may in the future restrict companies from paying amounts denominated in foreign currency or require that any such payment be made in Reais. Many factors could affect the likelihood of the Brazilian government imposing such exchange control restrictions, including the extent of Brazil's foreign currency reserves, the availability of sufficient foreign exchange on the date a payment is due, the size of Brazil's debt service burden relative to the economy as a whole and political constraints to which Brazil may be subject. There can be no certainty that the Brazilian government will not take such measures in the future.

The market value of securities issued by Brazilian companies is influenced by the perception of risk in Brazil and other emerging market countries, which may have a negative effect on the value of our investments in Oi and Contax and may restrict Oi and Contax's access to international capital markets

Economic and market conditions in other emerging market countries, especially those in Latin America, may influence the market for securities issued by Brazilian companies. Investors' reactions to developments in these other countries may have an adverse effect on the market value of securities of Brazilian issuers. Adverse economic conditions in other emerging market countries have at times resulted in significant outflows of funds from Brazil. Crises in other emerging countries or the economic policies of other countries, in particular the United States, may adversely affect investors' demand for securities issued by Brazilian companies, including Oi and Contax. Any of these factors could adversely affect the market price of the common or preferred shares of Oi and Contax and thereby reduce the value of our investment in those companies. Any of these factors could also impede the ability of Oi or Contax to access the international capital markets and finance their operations in the future on terms acceptable to it or at all.

Oi's fixed-line telecommunications services face increased competition from mobile services providers, other fixed-line service providers and cable television service providers, which may adversely affect its revenues and margins

Oi's fixed-line telecommunication services face increasing competition from mobile services as the prices for mobile services decline and approach those of fixed-line services. Oi expects that the number of fixed lines in service in Brazil will continue to stagnate or decline, as certain customers eliminate their fixed-line services in favor of mobile services, and the use of existing fixed lines to decline as customers substitute calls on mobile phones in place of fixed-line calls as a result of promotional mobile rates. The rate at which the number of fixed lines in service in Brazil may decline depends on many factors beyond our control, such as economic, social, technological and other developments in Brazil. For the year ended December 31, 2011, Oi's traditional local fixed-line telecommunication services represented 34.5% of the gross operating revenue of the Oi Companies. Because Oi derives a significant portion of its net operating revenue from its traditional local fixed-line telecommunication services, the reduction in the number of fixed-lines in service has negatively affected and is likely to continue to negatively affect Oi's net operating revenue and margins.

Oi also competes in the market for local fixed-line services with other fixed-line service providers, primarily with Empresa Brasileira de Telecomunica¸coes—Embratel (''Embratel''), Embratel's cable ˜ television subsidiary Net Servi¸cos de Comunica¸cao S.A. (''NET'') and GVT S.A. (''GVT''). In addition, ˜ Oi competes in each service region with smaller companies that have been authorized by the Brazilian National Telecommunications Agency (Agˆencia Nacional de Telecomunica¸coes ˜ , or ''ANATEL'') to provide local fixed-line services. Embratel, GVT and NET are each controlled by multinational companies that may have more significant financial and marketing resources, and greater abilities to access capital on a timely basis and on more favorable terms, than Oi.

Oi's loss of a significant number of fixed-line customers would adversely affect its operating revenues and results of operations.

Oi's mobile services face strong competition from other mobile services providers, which may adversely affect its revenues

The mobile services market in Brazil is extremely competitive. Oi faces competition from large competitors such as Vivo Participa¸coes S.A. (''Vivo''), Telecom Americas Group, which markets its ˜ services under the brand name ''Claro,'' and TIM Participa¸coes S.A. (''TIM''). Vivo, TIM and Telecom ˜ Americas Group are each controlled by multinational companies that may have more significant financial and marketing resources, and greater abilities to access capital on a timely basis and on more favorable terms, than Oi.

Oi's ability to generate revenues from its mobile services depends on its ability to increase and retain its customer base. Each additional customer subscribing to Oi's service entails costs, including sales commissions and marketing costs. Recovering these costs depends on Oi's ability to retain such customers. Therefore, high rates of customer churn could have a material adverse effect on the profitability of Oi's mobile service business.

Oi has experienced increased pressure to reduce its rates in response to pricing competition. This pricing competition often takes the form of special promotional packages, which may include, among other things, mobile handset subsidies, traffic usage promotions and incentives for calls made within a mobile services provider's own network. Competing with the service plans and promotions offered by competitors may cause an increase in Oi's marketing expenses and customer-acquisition costs, which has adversely affected and could continue to adversely affect Oi's results of operations. Oi's inability to compete effectively with these bundles of products and services could result in a loss of market share and adversely affect its operating revenues and profitability.

Oi's long-distance services face significant competition, which may adversely affect its revenues

In Brazil, unlike in the United States and many other countries, a caller chooses its preferred long-distance carrier for each long-distance call, whether originated from a fixed-line telephone or a mobile handset, by dialing such carrier's long-distance carrier selection code (Codigo de Sele¸ ´ cao de ˜ Prestadora). The long-distance services market in Brazil is highly competitive. Oi's principal competitor for long-distance services is TIM, which in 2010 began aggressively promoting its long-distance services with significant discounts. Generally, callers placing long-distance calls in Brazil from their fixed-line telephones tend to select the long-distance carrier affiliated with the provider of their fixed-line service. Similarly, callers placing long-distance calls in Brazil from their mobile telephones tend to select the long-distance carrier affiliated with the provider of their mobile or fixed-line service. However, increased competition from long-distance service providers has resulted in pressure on Oi's long-distance rates and adversely affected its revenue from these services. In addition, aggressive discounting by TIM during 2010 and 2011 has substantially reduced the market share of Oi in the long-distance market. Competition in the long-distance market may require Oi to increase its marketing expenses and/or provide services at lower rates than those it currently expects to charge for such

services. Competition in the domestic long-distance market has had and could continue to have a material adverse effect on Oi's revenues and margins.

Data transmission services are not subject to significant regulatory restrictions in Brazil, and as a result, Oi faces an increasing amount of competition in this business

Competition in data transmission services is not subject to significant regulatory restrictions and, therefore, the market is open to a large number of competitors. Some competitors, such as cable operators, offer telephone and broadband services that do not require them to use Oi's fixed-line network, thereby allowing them to reach Oi's customers without paying interconnection fees to Oi. Increasing competition in data transmission services may lead to rate reductions in this segment, adversely affecting the net operating revenue that Oi generate from this business. In addition, increased competition for data transmission customers may require Oi to increase its marketing expenses and capital expenditures and may lead to the loss of broadband customers, in each case leading to a decrease in Oi's profitability.

Oi has a substantial amount of existing debt, which could restrict its financing and operating flexibility and have other adverse consequences

As of December 31, 2011, the Oi Companies had total consolidated debt of R\$29,714.4 million. Oi is subject to certain financial covenants that limit its ability to incur additional debt. Its existing level of indebtedness and the requirements and limitations imposed by its debt instruments could adversely affect its financial condition or results of operations. In particular, the terms of some of these debt instruments restrict our ability, and the ability of our subsidiaries, to:

• incur additional debt;
• grant liens;
• pledge assets;
• sell or dispose of assets; and
• make certain acquisitions, mergers and consolidations.

Furthermore, some of Oi's debt instruments include financial covenants that require it and some of its subsidiaries to maintain certain specified financial ratios. Additionally, the instruments governing a substantial portion of its indebtedness contain cross-default or cross-acceleration clauses, and the occurrence of an event of default under one of these instruments could trigger an event of default under other indebtedness or enable the creditors under other indebtedness to accelerate that indebtedness.

If Oi is unable to incur additional debt, it may be unable to invest in its business and make necessary or advisable capital expenditures, which could reduce future net operating revenue and adversely affect its profitability. In addition, cash required to serve its existing indebtedness reduces the amount available to it to make capital expenditures.

If Oi's growth in net operating revenue slows or declines in a significant manner, for any reason, it may not be able to continue servicing its debt. If it is unable to meet its debt service obligations or comply with our debt covenants, it could be forced to renegotiate or refinance its indebtedness, seek additional equity capital or sell assets. It may be unable to obtain financing or sell assets on satisfactory terms, or at all.

Regulation and regulatory changes may have a material adverse effect on Oi's results

Telecommunications service providers in Brazil are subject to extensive regulation. ANATEL regulates, among other things, rates, quality of service and universal service goals, as well as competition among telecommunications service providers. Changes in laws and regulations, grants of new concessions, authorizations or licenses or the imposition of additional universal service obligations, among other factors, may adversely affect Oi's business, financial condition and results of operations.

Among the items on ANATEL's regulatory agenda are the following:

• ANATEL has proposed a General Plan on Competition Targets (Plano Geral de Metas de Competi¸cao˜ ), which contemplates the creation of three entities to manage information about telecommunications networks, act as an intermediary in contracts between telecommunications providers and supervise the offering of wholesale and retail data traffic services. The proposed General Plan on Competition Targets also addresses a variety of other matters, including criteria for the evaluation of telecommunications providers to determine which providers have significant market power, regulations applicable to the wholesale markets for trunk lines, backhaul, access to internet backbone and interconnection services, and regulations related to partial unbundling and/or full unbundling of the local fixed-line networks of the public regime service providers. Oi expects these new regulations, as they may be modified as a result of ANATEL's further analysis, to be adopted in 2012.
• ANATEL has proposed new regulations under which it would modify the Factor X applicable to the determination of rate increases available to public concessionaires providing fixed-line services. Oi expects these new regulations, as they may be modified as a result of ANATEL's further analysis, to be adopted in 2012.

We cannot predict when regulations regarding these matters will be adopted or whether these regulations will be adopted as proposed. Some of these regulations, if adopted, may have adverse effects on Oi's revenues, costs and expenses, results of operations and financial position.

Certain legislative bills seeking to terminate monthly subscription fees charged by local fixed-line service providers have been submitted to the Brazilian Congress and remain pending. In March 2008, a special committee was formed in the Brazilian House of Representatives to discuss the various proposed bills on this issue. As of the date of this annual report, no action had been taken by the committee. During 2011, monthly subscription fees represented 23.4% of Oi's gross operating revenue. The enactment of legislation terminating the monthly subscription fees would have a material adverse effect on Oi's results of operations.

We cannot predict whether ANATEL, the Brazilian Ministry of Communications (Minist´erio das Comunica¸coes ˜ ) or the Brazilian government will adopt other telecommunications sector policies in the future or the consequences of such policies on Oi's business and the business of our competitors.

Oi's local fixed-line and domestic long-distance concession agreements are subject to periodic modifications by ANATEL, and Oi's bids for new concessions upon the expiration of its existing concessions may not be successful

Oi provides fixed-line telecommunications services in certain regions of Brazil pursuant to concession agreements with the Brazilian government. These concession agreements expire on December 31, 2025 and may be amended by the parties every five years prior to the expiration date. In connection with each five year amendment, ANATEL has the right, following public consultations, to impose new terms and conditions in response to changes in technology, competition in the marketplace and domestic and international economic conditions.

Oi's obligations under the concession agreements may be subject to revision in connection with each future amendment. Any future amendments could impose requirements on Oi that could require it to undertake significant capital expenditures or could modify the rate-setting procedures applicable to it in a manner that would significantly reduce the operating revenues that Oi generates from its fixed-line businesses. If the amendments to Oi's concession agreements have these effects, its business, financial condition and results of operations could be materially adversely affected.

Oi expects the Brazilian government to offer new concessions in competitive auctions prior to the expiration of the existing concession agreements. Oi may participate in such auctions, but its existing fixed-line and domestic long-distance concession agreements will not entitle Oi to preferential treatment in these auctions. If Oi does not secure concessions for its existing service areas in any future auctions, or if such concessions are on less favorable terms than current concessions, Oi's business, financial condition and results of operations would be materially adversely affected.

Oi's local fixed-line and domestic long-distance concession agreements, as well as its authorizations to provide personal mobile services, contain certain obligations, and its failure to comply with these obligations may result in various fines and penalties imposed on Oi by ANATEL

Oi's local fixed-line and domestic long-distance concession agreements contain terms reflecting the General Plan on Universal Service (Plano Geral de Metas de Universaliza¸cao˜ ), the General Plan on Quality Goals (Plano Geral de Metas de Qualidade) and other regulations adopted by ANATEL, the terms of which could affect Oi's financial condition and results of operations. Oi's local fixed-line concession agreements also require it to meet certain network expansion, quality of service and modernization obligations in its concession regions. In the event of noncompliance with ANATEL targets in any one of these states, ANATEL can establish a deadline for achieving the targeted level of such service, impose penalties and, in extreme situations, terminate the applicable concession agreement for noncompliance with its quality and universal service obligations.

On an almost weekly basis, Oi receives inquiries from ANATEL requiring information from it on its compliance with the various service obligations imposed by its concession agreements. If Oi is unable to respond satisfactorily to those inquiries or comply with its service obligations under its concession agreements, ANATEL may commence administrative proceedings in connection with that noncompliance. Oi has received numerous notices of the commencement of administrative proceedings from ANATEL, mostly due to its inability to achieve certain targets established in the General Plan on Quality Goals and the General Plan on Universal Service, among others. As of December 31, 2011, the Oi Companies had recorded provisions in the amount of R\$941 million in connection with fines sought to be imposed by ANATEL on a consolidated basis. Additional fines from ANATEL or fines in excess of the provisioned amount could adversely impact Oi's financial condition and results of operations.

In addition, Oi's authorizations to provide personal mobile services contain certain obligations requiring it to meet network scope and quality of service targets. If Oi fails to meet these obligations, it may be fined by ANATEL until it is in full compliance with its obligations and, in extreme circumstances, Oi's authorizations could be revoked by ANATEL.

Oi and Contax are subject to numerous legal and administrative proceedings, which could adversely affect their business, results of operations and financial condition

Oi and Contax are subject to numerous legal and administrative proceedings. It is difficult to quantify the potential impact of these legal and administrative proceedings. Both Oi and Contax classify the risk of loss from legal and administrative proceedings as ''probable,'' ''possible'' or ''remote.'' Each company makes provisions for probable losses but does not make provisions for possible and remote losses. As of December 31, 2011, Oi and Contax, together, had recorded provisions of R\$7,059.5 million for probable losses relating to various tax, labor and civil legal and administrative proceedings

against them, including provisions of R\$4,164.5 million relating to civil proceedings, R\$1,979.9 million relating to labor proceedings and R\$915.1 million relating to tax proceedings. Portugal Telecom's proportionally consolidated portion of these probable liabilities amounted to A760.1 million.

In addition, as of December 31, 2011, Oi and Contax, together, had claims against them totalling R\$21,553.3 million for proceedings classified as ''possible'' and for which they had made no provisions, including R\$1,297.1 million relating to civil proceedings, R\$1,930.7 million relating to labor proceedings and R\$18,325.5 million relating to tax proceedings. Portugal Telecom's proportionally consolidated portion of these possible liabilities amounted to A2,345.8 million.

Oi and Contax are not required to disclose or record provisions for proceedings in which their management judges the risk of loss to be remote. However, the amounts involved in certain of the proceedings in which Oi and Contax believe their risk of loss is remote could be substantial.

Consequently, the losses to Oi and Contax, and therefore to Portugal Telecom, could be significantly higher than the amounts for which we have recorded provisions. If Oi or Contax were to be subject to unfavorable decisions in any legal or administrative proceedings and the losses in those proceedings were to significantly exceed the amount for which it has provisioned or involve proceedings for which it has made no provision, its results of operations and financial condition may be materially adversely affected. Even for the amounts recorded as provisions for probable losses, a judgment against Oi or Contax would have an effect on their cash flow if they are required to pay those amounts. Unfavorable decisions in these legal proceedings may, therefore, reduce the liquidity of Oi or Contax and adversely affect their, and consequently Portugal Telecom's, business, financial condition and results of operations.

Oi is subject to delinquencies of its accounts receivables. If it is unable to limit payment delinquencies by its customers, or if delinquent payments by its customers increase, its financial condition and results of operations could be adversely affected

Oi's business significantly depends on its customers' ability to pay their bills and comply with their obligations to it. In 2011, Oi recorded provisions for doubtful accounts in the amount of R\$1,093.8 million, primarily due to subscribers' delinquencies. As of December 31, 2011, Oi's provision for doubtful accounts, as a percentage of its net operating revenues, was approximately 5%.

ANATEL regulations prevent Oi from implementing certain policies that could have the effect of reducing delinquency, such as service restrictions or limitations on the types of services provided based on a subscriber's credit record. If Oi is unable successfully to implement policies to limit subscriber delinquencies or otherwise select its customers based on their credit records, persistent subscriber delinquencies and bad debt will continue to adversely affect Oi's operating and financial results.

In addition, if the Brazilian economy declines due to, among other factors, a reduction in the level of economic activity, depreciation of the Real, an increase in inflation or an increase in domestic interest rates, a greater portion of Oi's customers may not be able to pay their bills on a timely basis, which would increase its provision for doubtful accounts and adversely affect its financial condition and results of operations.

Risks Related to Our Other International Investments

Adverse political, economic and legal conditions in the countries where we have investments may hinder our ability to receive dividends from our international subsidiaries

The governments of many of the countries where we have investments have historically exercised, and continue to exercise, significant influence over their respective economies and legal systems. Countries where we have investments may enact legal or regulatory measures that restrict the ability of our subsidiaries to make dividend payments to us. Similarly, adverse political or economic conditions in these countries may hinder our ability to receive dividends from our subsidiaries. We receive significant amounts in dividends each year from our international investments, particularly in Africa, and a limitation on our ability to receive a material portion of those dividends could adversely affect our cash flows and liquidity.

In addition, our investments in these regions are exposed to political and economic risks that include, but are not limited to, exchange rate and interest rate fluctuations, inflation and restrictive economic policies and regulatory risks that include, but are not limited to, the process for the renewal of licenses and the evolution of regulated retail and wholesale tariffs. In addition, our ventures in international markets face risks associated with increasing competition, including due to the possible entrance of new competitors and the rapid development of new technologies.

The development of partnerships in these markets raises risks related to the ability of the partners to jointly operate the assets. Any inability of us and our partners to operate these assets may have a negative impact on our strategy and on our results of operations.

All these risks may have material adverse effects on our results of operations.

We may continue to engage in acquisitions and divestments, which may be disruptive and require us to incur significant expenses

From time to time, we have made strategic acquisitions in order to obtain various benefits such as a desire to access to growing international markets and broaden our customer base. Future acquisitions could result in the incurrence of contingent liabilities and an increase in amortization expenses related to intangible assets, which could have a material adverse effect upon our business, financial condition and results of operations. Risks we could face with respect to acquisitions include:

• difficulties in the integration of the operations, technologies, products and personnel of the acquired company;
• risks of entering markets in which we have no or limited prior experience;
• potential loss of employees;
• diversion of management's attention away from other business concerns; and
• expenses of any undisclosed or potential legal liabilities of the acquired company.

From time to time, we also divest parts of our business to monetize investments, obtain funds to make other investments or optimize our operations. Any decision to dispose of or otherwise exit investments may result in the recording of special charges, particularly for any business that we consolidate or proportionally consolidate, such as workforce reduction costs and industry and technology-related write-offs. We may not be successful in consummating future acquisitions or divestments on favorable terms or at all. The risks associated with such acquisitions and divestments could have a material adverse effect upon our business, financial condition and results of operations.

We are a party to joint ventures and partnerships that may not be successful and may expose us to future costs

We are partners in joint ventures and partnerships. Our partnering arrangements may fail to perform as expected for various reasons, including an incorrect assessment of our needs or the capabilities or financial stability of our strategic partners. Our ability to work with these partners or develop new products and solutions may become constrained, which could harm our competitive position in the market. Additionally, our share of any losses from or commitments to contribute additional capital to such partnerships may adversely affect our results of operations or financial position.

Risks Relating to Our ADSs and Ordinary Shares

An ADS holder may face disadvantages compared to an ordinary shareholder when attempting to exercise voting rights

Holders of our ADSs may instruct the depositary to vote the ordinary shares underlying the ADSs. For the depositary to follow the voting instructions, it must receive them on or before the date specified in our voting materials. The depositary must try, as far as practical, subject to Portuguese law and our articles of association, to vote the ordinary shares as instructed. In most cases, if the ADS holder does not give instructions to the depositary, it may vote the ordinary shares in favor of proposals supported by our Board of Directors, or, when practicable and permitted, give a discretionary proxy to a person designated by us. We cannot be certain that ADS holders will receive voting materials in time to ensure that they can instruct the depositary to vote the underlying ordinary shares. Also, the depositary is not responsible for failing to carry out voting instructions or for the manner of carrying out voting instructions. This means that ADS holders may not be able to exercise their right to vote and there may be nothing they can do if their ordinary shares or other deposited securities are not voted as requested.

If you are a U.S. tax resident, you will not be eligible for the reduced rates of Portuguese withholding tax on dividends under the U.S.-Portugal income tax treaty unless you fill out a form required by the Portuguese tax authorities and get it certified by the U.S. Internal Revenue Service

If you are a U.S. tax resident, you will not be eligible for the reduced rates of Portuguese withholding tax on dividends under the U.S.-Portugal income tax treaty unless you fill out a form required by the Portuguese tax authorities and have it certified by the U.S. Internal Revenue Service.

Under Portuguese law, dividends paid by Portuguese companies are subject to withholding tax at a 21.5% rate. Dividends placed in bank omnibus accounts (except where the identity of the effective beneficiary is disclosed), are subject to withholding tax at a rate of 30%.

However, under the U.S.-Portugal income tax treaty, the withholding tax rate on dividends distributed to U.S. tax residents may be reduced, as a general rule, to 15%. In order to apply the reduced treaty rate, confirmation that each shareholder is eligible for the benefits of the treaty is required. A specific form (Form 21-RFI of the Tax and Customs Authority (AT—Autoridade Tributaria e ´ Aduaneira) of the Portuguese Ministry of Finance), duly certified by the U.S. Internal Revenue Service, must be received by Banco Esp´ırito Santo, the custodian for the depositary, if you are a holder of ADSs, or your financial intermediary, if you are a holder of Portugal Telecom ordinary shares, prior to the date the dividends are made available to shareholders.

If this form is not available as of the relevant date, Portuguese withholding tax will be levied at the 21.5% rate. If you are able to submit the form to the custodian for the depositary, if you are a holder of ADSs, or to your financial intermediary, if you are a holder of ordinary shares, no later than the 20th day of the month following the payment of the dividend, we believe that the custodian or the financial intermediary, as the case may be, should release the 6.5% excess Portuguese withholding tax to you. However, we cannot guarantee that the custodian or the financial intermediary will do so.

In addition, the 6.5% excess Portuguese withholding tax may be subsequently reimbursed by the Portuguese tax authorities pursuant to specific claims of individual shareholders on Form 22-RFI of the Tax and Customs Authority of the Portuguese Ministry of Finance, duly certified by the U.S. Internal Revenue Service and presented to the Portuguese tax authorities within two years following the last day of the year in which the dividends were made available. See ''Item 10—Additional Information— Taxation—Dividends.''

If you are an investment fund, pension fund or trust holding ADSs or ordinary shares, you should be aware that, under a guidance note issued by the Portuguese tax authorities, in order to benefit from the Treaty provisions, you must comply with certain additional requirements that are described in ''Item 10—Additional Information—Taxation—Dividends.'' Although this is not demanded by the Treaty, the Portuguese tax authorities take the position that the compliance with the applicable requirements should be certified by the U.S. Internal Revenue Service, using a form or other mean specifically permitted for this purpose. If you are an investment fund, pension fund or trust, you should contact your tax advisor for more information regarding the requirements of the Portuguese tax authorities.

You should know that receiving certification of a Form 21-RFI or Form 22-RFI from the U.S. Internal Revenue Service can be a lengthy process. In addition, although Portuguese law states that the excess withholding tax should be reimbursed within one year from the date the claim was submitted, we cannot guarantee if or when you will receive any reimbursement of the 6.5% excess Portuguese withholding tax even if you fill out Form 22-RFI and are eligible to receive reimbursement as described above. You should contact your tax advisor if you wish to fill out Form 21-RFI or Form 22-RFI to claim eligibility for the benefits of the Treaty.

ITEM 4—INFORMATION ON THE COMPANY

Overview

We provide telecommunications services in Portugal, in Brazil through our strategic partnerships with Oi and Contax, and in certain countries in sub-Saharan Africa and Asia. Our business in analyzed and discussed based on two reportable segments: Telecommunications in Portugal and Telecommunications in Brazil—Oi. Within these segments, we report revenues in the following customer categories for our telecommunications services in Portugal and Brazil: residential customers, personal customers, enterprise customers and other revenues. In addition to our operating reportable segments, we have other businesses that do not rise to a threshold that would require disclosure as a reportable segment. Revenues from our Portuguese and international operations accounted for 48% and 52% of our consolidated revenues in 2011, respectively, primarily reflecting 47% and 39% of our consolidated revenues related to the above-mentioned Portuguese and Brazilian (Oi) telecommunications businesses, respectively, as well as 6% of our consolidated revenues from the proportional consolidation of Contax and 4% of our consolidated revenues from our Africatel businesses.

Portugal. In Portugal, we provide services in the following customer categories:

• Residential services, which include integrated networks inside the customer's home, enabling the simultaneous connection of multiple devices, including fixed line telephone, TV (including Internet Protocol Television and direct-to-home satellite Pay-TV services), game consoles, PCs, laptops, tablets and smartphones. We provide these services through our subsidiaries, in particular PT Comunica¸coes, S.A. (''PT Comunica¸ ˜ coes''). ˜
• Personal services, which are mobile telecommunications services, such as voice, data and Internetrelated multi-media services provided to personal (i.e., individual) customers through our subsidiary TMN—Telecomunica¸coes M ˜ oveis Nacionais, S.A. (''TMN''). ´
• Enterprise services, including Corporate and SME/SoHo services, which provide our corporate and medium and small business customers with integrated data and business solutions, as well as IT/ IS and business process outsourcing (BPO) services.
• Wholesale and other services, which primarily include wholesale telecommunications services, public pay telephones, the production and distribution of telephone directories and other services in Portugal.

Brazil. After the completion of the corporate reorganization of Oi that occurred on April 9, 2012, we hold a 23.25% economic interest in Oi S.A., one of the largest telecommunications companies in Brazil, and we are parties to a series of shareholder agreements with other shareholders of Oi that allow us to jointly control Oi. We completed our investment in Oi on March 28, 2011, and we held a 25.3% economic interest in Oi throughout 2011. We have proportionally consolidated the results of operations of Oi in our results of operations since April 1, 2011. Since April 1, 2011, we have proportionally consolidated 25.6% of TmarPart, the parent company of Oi S.A., in our consolidated financial statements, reflecting our ownserhip interest in TmarPart. TmarPart, in turn, fully consolidates Oi S.A.

Oi provides telecommunications services in Brazil, including:

• Residential services, which include local fixed-line services and domestic long-distance services, primarily in Regions I and II of Brazil, data transmission services and usage of Oi's network to complete calls initiated by customers of other telecommunication services providers to Oi's fixed-line network (fixed-line interconnection services).
• Personal services, which include mobile telecommunications services throughout Brazil (Regions I, II and III) utilizing 2G and 3G technology, including voice and data transmission services, and usage of Oi's network to complete calls initiated by customers of other telecommunication services providers to Oi's moblie network (mobile interconnection services).
• Enterprise services, which include fixed-line telecommunications services, mobile telecommunications services, advanced voice services, such as 0800 (toll free) services, customized infrastructure and storage capacity and access to advanced data centers, in each case to corporate and medium and small businesses.
• Other services, which include subscription television services, including cable and DTH television services, ISP services, operation of the iG internet portal (which Oi agreed to sell in 2012) and a mobile phone payment system and call center.

The Brazilian regions described above consist of Region I (which consists of 16 Brazilian states located in the northeastern and part of the northern and southeastern regions), Region II (which consists of the Federal District and nine Brazilian states located in the western, central and southern regions) and Region III (consisting of the State of Sao Paulo). ˜

Other International Assets. Concurrently with our investment in Oi, we acquired a 16.2% economic interest in CTX Participa¸coes S.A. (''CTX''), the parent company of Contax Participa¸ ˜ coes S.A. ˜ (''Contax Participa¸coes'') and Contax S.A. (''Contax''), which provides contact center services in Brazil. ˜ Even before our investment in Contax, we provided call center services in Brazil through our subsidiary Dedic, S.A. (''Dedic''), and Dedic's subsidiary GPTI—Tecnologias de Informa¸cao, S.A. (''GPTI'') ˜ provided IT/IS services in Brazil. On June 30, 2011, we merged Dedic and GPTI into Contax, and our economic interest in Contax increased to 19.5%. We have proportionally consolidated the results of operations of Contax in our results of operations since April 1, 2011, and Contax's results of operations have included the results of operations of Dedic and GPTI since July 1, 2011.

In addition, we have significant interests in telecommunications companies in Angola, Cape Verde, Namibia and Sao Tom ˜ e and Principe in Africa and in Macau and East Timor in Asia. ´

The information on our website is not part of this report. The website address is included as an indicative textual reference only.

Strategy

We are an international operator focused on three main geographies: Portugal, Brazil and sub-Saharan Africa. We remain committed to discipline in our strategy, cost, operations and financial performance, and we aim to focus our resources on our core businesses and core regions. Our strategy continues to be guided by five key medium-term objectives:

• grow our customer base to 100 million customers;
• increase our exposure to international businesses up to two-thirds of our revenues;
• reinforce leadership in all market sectors;
• achieve performance in the top quartile of European companies in shareholder return and operating and financial results; and
• be a reference company in sustainability efforts.

Our success in achieving these goals is subject to a number of uncertainties, including the factors described in ''Item 3—Key Information—Risk Factors.''

Some of our specific strategies to achieve these goals in our core regions include the following:

Portuguese Operations

• Reap the benefits of the functional merger of our mobile business (TMN) and wireline business (PT Comunica¸coes), with a stronger focus on customer segments. ˜ We recently implemented a functional merger of our mobile and wireline businesses, and our new organizational structure is based on two principles:
  • Stronger customer focus: We abandoned a company structure organized around fixed and mobile platforms in favor of a structure centred on the specific needs of each segment, implementing a new organization around five customer categories: Residential, Personal, SMEs/SoHos, Corporate and Wholesale. We report SME/SoHo and Corporate businesses together as Enterprise services.
  • Superior operational efficiency: We eliminated several decision processes and layers and reduced the number of officers, enabling a leaner and more agile company to effectively compete in an increasingly challenging environment.

Effectively execute projects for next generation networks and improvements in distribution and customer care. We seek to act at the forefront of fiber rollout in Portugal and in Europe, having already covered 1.6 million homes passed with Fiber-to-the-Home (''FTTH'') available and under construction, making Portugal the most penetrated country in Europe with 46% of households covered (an initiative that was recognised by the FTTH Council Europe with the innovation award for Deployment and Operation of FTTH Networks). We aim to leverage our FTTH investment not only to provide advanced and high-speed data and video services to our corporate and residential customers but also to cover TMN's base stations with fiber to allow higher download and upload speeds for TMN's data customers and to pave the way for the rollout of Long Term Evolution (''LTE'') services. We launched LTE services in March 2012 with a network covering 20% of population in Portugal, and we aim to increase coverage to 80% of the population by April 2012 and to 90% by the end of 2012. In addition, we operate the most comprehensive Wi-Fi network in Portugal, with around 1,600 hot spots, and we intend to use that network to enable traffic offloads from mobile to fixed networks. Finally, we are implementing a program to rejuvenate our field force to improve its quality and responsiveness against a backdrop of increasingly complex television and IT services.

• Residential services: provide an outstanding and sophisticated multi-screen Pay-TV experience. We believe the growing connectivity available on next generation access networks will continue to be an overriding trend among residential customers, enabling the simultaneous connection of multiple devices through wireless and wireline networks inside the customer home (TVs, games consoles, PCs, laptops, tablets and smartphones). We believe multi-screen TV is a key lever for differentiating our services, and our nationwide Pay-TV service under the Meo brand (''Meo'') is converging towards a seamless offering on the TV, PC and smartphone. We also expect cloudbased services to become an increasingly popular reality, allowing easy access to software and technology and higher security in the storage of key information. We are following these trends, having recently launched several new applications and services, including (1) Meo Go, a live-TV service available on Wi-Fi and 3G/4G mobile networks, (2) Meo Kanal, an application aiming at bringing the social media features to the TV set and (3) Meo Games, an on-demand gaming service. We seek partnerships with content and technology suppliers in order to enhance our service and obtain a competitive advantage.
• Personal services: use mobile data and convergence of services as key growth levers. We seek to capitalize on the increased penetration of smartphones, laptops and other mobile data devices, coupled with the explosive growth and proliferation of data services and apps. We offer TV

(Meo Mobile), music (Music Box) and access to social networks through aggregator and convergent services that leverage our Sapo brand and know-how. We also use partnerships with key suppliers, using its brand or third-party brands, to maintain distinctive and attractive offerings of smartphones, tablets and laptops. In addition, we remain focused on designing new tariff plans, like the ''e,'' a new prepaid plan, and the ''Unlimited'' post-paid plan, which are simpler and customizable and aimed at catalyzing the upselling of Internet services and seeking to lock in high value customers, shifting way from pricing competition.

• Enterprise services: provide new services for businesses by leveraging our transport and access networks. Through investments in infrastructure and telecom-IT convergence, we intend to develop and market advanced integrated solutions for the corporate and SME segments aimed at increasing our penetration of IT/IS and BPO services in Portugal. We will also seek to leverage the new data center we are constructing in Covilha, Portugal and our cloud computing ˜ offering, in partnership with Cisco and Microsoft, to supply new and distinctive services to the market.
• Reinforce leadership in the market sectors where we operate. Through our Meo Pay-TV service, we are turning around our residential business, leveraging our position as a major integrated operator and aiming to offer broad and convergent products and services. In a converging world where individuals increasingly need to contact, communicate and consume seamless data services through all types of devices everywhere—at their workplaces, at home or on the move—we believe our skills and ability to offer integrated services are a competitive advantage in Portugal.
• Emphasize customer service. In the context of major market transformations and economic uncertainty, understanding customer needs and addressing these needs by ensuring world-class execution is a crucial priority. We seek to develop trust-based relationships with our customers that will encourage them to adopt increasingly complete products and service packages for longer periods, allowing us to increase our revenues.

International Operations

• Maximize the strategic value of our international assets and reinforce our focus on Brazil and sub-Saharan Africa. The Brazilian market remains a priority to us as a driver for growth. Africa will continue to be an important source of growth as well, where we seek to reinforce partnerships and explore value-creating investment opportunities.
• Brazil: focus on data growth and convergence of services. In Brazil, through our investment in and partnership with Oi, we will focus our efforts on leveraging our experience in developing new and technologically advanced solutions for corporate customers, fixed-mobile convergent offers, mobile broadband, Pay-TV and triple-play services to contribute to further improve Oi's operational and financial performance. We seek to build upon Oi's strong presence in the Brazilian market and its potential for future growth.
• Africa and Asia: pursue consolidation of practices among our investments and consider opportunistic M&A transactions. We continue to focus on improving the efficiency of our international operations through sharing best practices among all our investments and through increased proximity achieved by maintaining frequent contact with top management of those investments in person or by video-conference to better monitor key developments in each region.
• Focus on operational and commercial excellence of all assets and promote the sharing of best practices. By reinforcing operational and commercial excellence in all our operations and promoting the sharing of best practices among all our businesses, we seek to tap the full potential of each business, taking into account the development of each market and the competitive position of our investments.

Focus on Innovation and Execution

• Continue to implement our structured approach to innovation and related partnerships. We pursue a structured approach to innovation aimed at establishing a balanced portfolio of projects focused on two key variables: risk level and maturity. Three main categories are defined under this approach: (1) incremental innovation (ordinary course of business, low-risk and short-term optimizations), (2) planned innovation (business development, medium-term and medium-risk developments) and (3) exploratory innovation (structural projects, which are long-term and high-risk by nature). We also seek to leverage a network of partnerships with key institutions: (1) technological partnerships for the development of new solutions and services (e.g., agreements with Cisco, Corning, Samsung, LG, Huawei and ZTE), (2) partnerships, aimed at sharing best practices and establishing joint collaboration in innovation and research and development (''R&D'') (e.g., a protocol we signed with Singtel), (3) protocols with universities to foster joint R&D and knowledge-building efforts (e.g., our partnership with Carnegie Mellon University and several Portuguese universities) and (4) R&D partnerships aimed at developing new technological solutions (e.g., agreements with INESC Inova¸cao and Instituto de ˜ Telecomunica¸coes). ˜

Residential ARPU was up by 5.4% to A30.8.

Pay-TV Services

In 2008, we announced the launch of our nationwide Pay-TV offer, which includes DTH (satellite) and IPTV offers over ADSL and fiber. Our television strategy is based on a multiplatform concept that aims to provide similar content and user experiences across television, PCs and mobile phones. Meo is our TV brand across the various platforms, namely at home (through IPTV and satellite), through mobile telephones (through Meo Mobile) or through personal computers (through Meo Go). Meo provides access to a comprehensive content offering, with more than 150 TV channels and thousands of video-on-demand titles. We offer tiered packages of channels, as well as on-demand availability that can be subscribed for directly through the TV set in real time. Meo also provides access to advanced features, such as digital recording and pause live-TV. The set-top boxes in the Meo service are all HD-compliant, using MPEG4. We were the first operator in Portugal to introduce HDTV and have the most extensive video-on-demand offer in the market.

Meo surpassed the one million customer mark in November 2011, three-and-a-half years after the service was launched on a nationwide basis in April 2008. Meo currently has 1,042 thousand customers and a 35% market share, according to ANACOM.

We market Meo as a Pay-TV service offering a seamless multiscreen experience with live TV channels, video on demand, games and music on demand available on multiple devices. We offer HD and 3D channels, thousands of video on demand titles and interactivity with respect to anchor programmes (e.g., ´Idolos, Secret Story, Biggest Loser). Meo also offers customised interactive applications accessed through the remote control and covering areas such as (1) News, including a personalized newscast application, developed in a partnership with RTP, the state-owned free-to-air channel, (2) Sports, including a soccer application, a surf application and specific sports channel applications, (3) Music, including MusicBox, a multiscreen music streaming service, a radio streaming application and a karaoke application, (4) Kids, including a comprehensive children's portal where kids can access channels, video on demand content, music clips, karaoke, games and tailored educational content, (5) Convenience, including applications for weather, traffic, pharmacies and other needs and (6) Personal content, including an online photo storage application.

During 2011, we continued to introduce to new Pay-TV content and products. Taking advantage of the popularity of the second season of Secret Story, a reality show on the Portuguese free-to-air channel TVI, Meo launched an exclusive Secret Story channel in late September 2011, providing 24-hour live feed of the Secret Story house with an interactive application that allowed customers to select the camera from which they wanted to follow contestants in the show. After its launch, the channel achieved over 10% audience share.

With the free-to-air channel RTP, Meo launched an interactive application that allows customers to create their own news playlists by selecting and aggregating categorised news clips from a catalog automatically collected and categorized by Meo and RTP throughout the day. Meo also launched a radio application that brings together 25 radio stations on the TV screen.

In the fourth quarter of 2011, Meo launched ''Meo Go'', an ''over the top,'' or ''OTT,'' service that allows content mobility among the home screen and multiple devices outside the home. Meo Go made 60 live TV channels and its video on demand service available on smartphones, tablets and personal computers from all major operating systems (iOS, Android and Windows Phone7).

In February 2012, Meo launched ''Meo Kanal,'' an application that allows customers to produce, edit and share multimedia content on television with other Meo customers. The contents can be accessed through the Meo remote control. Meo Kanal allows customers to create free private areas, requiring an access PIN that is shared only among family members, friends or any other desired group, or free public areas, accessible to the whole Meo community. Meo Kanal finally brings the social network experience to TV. This innovative application has already surpassed the 10,000-area mark.

Fixed Line Services

We had approximately 3,557 thousand fixed retail acesses in service as of December 31, 2011, excluding external supplementary lines, direct extensions and active multiple numbers. Within retail accesses, we report:

• traffic-generating lines held by subscribing customers;
• carrier pre-selection lines, which are lines of competitors for which those customers have elected to use our services;
• fixed broadband retail lines; and
• Internet protocol television (''IPTV'') customers using our Meo Pay-TV services.

All of our local switches in Portugal have been digital since 1999. Digital technology is used on all long distance and trunk connections. This level of digitalization of our fixed line network permits us to market and provide network-based value-added services, such as call waiting, call forwarding and voice mail, resulting in increased line usage. We cover 1.6 million homes in Portugal with our

Fiber-to-the-Home (''FTTH'') network. Our network, which is developed in urban areas, is a strategic investment to improve our competitiveness among residential customers, where we can offer distinctive Pay-TV and bundled offers.

Over the last decade, total traffic on our fixed line network has decreased, primarily because consumers have increasingly used mobile services instead of fixed line services and because of the migration of dial-up Internet users to Asymmetric Digital Subscriber Lines (''ADSL''). In fact, the number of active mobile cards (the mobile equivalent of main lines) exceeds the number of fixed line main lines in Portugal. We have responded to this trend by encouraging the use of our fixed line network for bundled services, including triple-play packages that include fixed telephone services, broadband internet access and Pay-TV services. Our Meo Pay-TV service has been the major source of growth within our residential services since its introduction in 2008, as described in more detail below.

We are required to provide carrier selection to our customers for all kinds of traffic. See ''—Regulation-Portugal—Number Portability and Carrier Selection.'' Carrier selection has been an additional factor that has contributed to the reduction in traffic on our network.

Components of Revenue

Our revenues from residential customers are derived from the following components:

• Service revenues, which are the revenues we generate from providing fixed telephone services, broadband internet access and Pay-TV services. These revenues generally consist of:
  • Fixed charges, including network access charges based on a monthly line rental and an initial installation fee, as well as, in most cases, a monthly fee from pricing packages, which can include broadband and Pay-TV services; and
  • Traffic, including charges for the use of our fixed line network based on rates dependent on the amount and type of usage.
• Sales and other revenues, which are revenues from the sale of telephone, broadband and Pay-TV equipment and other revenues, such as sales commissions.

Suppliers

For our fixed line network and Pay-TV services in 2011, we obtained telephones and equipment for our voice, broadband and Pay-TV services from several suppliers, including Alcatel, Ericsson and Novabase, and we obtain television content, including premium channels, from several national and international suppliers.

Personal Customers

We provide telecommunications and data mobility services for a variety of personal devices, including traditional cell phones, smartphones, tablets and laptops through our mobile business. We conduct our mobile business in Portugal through our wholly owned subsidiary TMN. TMN is the leading provider of mobile voice, data and Internet services in Portugal in terms of the number of active mobile cards connected to its network, as well as by revenues and margins, based on information from the other operators' releases.

The following table sets forth the total number of mobile customers, net additions and other information as of the dates indicated.

(1) Minutes of Usage (''MOU'') is monthly average of outgoing traffic in minutes per average number of users in the period.

(2) ''n.a.'' means that this breakdown was not reported separately for the year ended December 31, 2009.

(3) Subscriber Acquisition and Retention Cost (''SARC'') equals (70% of marketing and publicity costs + commissions + subsidies) / (gross additions + upgrades).

The number of mobile customers, including voice and broadband customers, remained stable in 2011 with a slight decline of 0.5% from previous year. In fourth quarter of 2011, customer net additions reached 60 thousand, showing improved performance both in postpaid customers (10 thousand net additions), building on the commercial success of the ''Unlimited'' tariff plans and on the continued growth of mobile broadband customers and prepaid customers, supported by the solid performance of the ''e nunca mais acaba'' tariff plans.

Following improvements throughout the year through September 2011, personal revenue trends ceased to improve in the fourth quarter of 2011 and were affected by economic conditions, including the reductions in the net wages and salaries of civil servants and retirees, which also resulted in lower consumer confidence. Customer revenues in 2011 declined 8.2% to A617.7 million from the previous year, due in part to reduced revenues from mobile broadband services. Service revenues in the personal customer segment declined by 10.9% in 2011 as a result of the decline in interconnection revenues by 29.9% to A67.7 million, reflecting the regulated declines in mobile termination rates.

Mobile voice traffic in terms of minutes grew by 6.5% to 6,289 billion minutes in 2011, compared to 5,903 billion minutes in 2010. Average monthly usage per subscriber increased by 5.7% to 89 minutes in 2011, compared to 84 minutes in 2010, primarily because of new commercial offers aimed at providing seamless, integrated voice services.

Mobile Network

We provide mobile telephone services using the GSM and UMTS technologies. Within our GSM offering, we provide services in the 900 MHz and 1800 MHz band spectrums. GSM and UMTS are European and worldwide standards using digital technology.

In 2011, ANACOM held a multiband auction for the provision of electronic communications services based on LTE (Long Term Evolution) technology whose bidding phase concluded on November 30, 2011. TMN bid for and acquired the rights of use for the 800 MHz, 1800 MHz and 2.6 GHz frequencies with a duration of 15 years:

• 2 10MHz in the 800 MHz band for a final price of A90.0 million;
• 2 14MHz in the 1800 MHz band for a final price of A11.0 million; and
• 2 20MHz in the 2.6 GHz band for a final price of A12.0 million.

In March 2012, ANACOM formally allocated to TMN the above-mentioned rights. In addition, the license unifies the previous GSM and UMTS licenses issued by ANACOM. The license imposes certain requirements on TMN, including the following:

• Mobile network obligations for 800 MHz: TMN must enter into agreements with Mobile Virtual Network Operators (MVNOs) and national roaming agreements with operators with rights of use on frequencies greater than 1GHz.
• Coverage obligations for 800 MHz: For each lot of 2 5 MHz in the 800MHz band, TMN must cover a maximum of 80 municipal areas out of 480 municipal areas without adequate broadband coverage.

For more information about our licenses, see ''—Regulation—Portugal—Summary of Our Concession and Existing Licenses and Authorizations—TMN's Mobile Service Licenses.''

We paid spectrum fees in 2011, 2010 and 2009 of A17 million, A21 million and A24 million, respectively, for the use of our 900 MHZ and 1800 MHZ GSM network and our UMTS network. These spectrum fees are recorded as an operating expense in our financial statements.

In recent years, we have made significant investments in our second and third generation networks. As a result of our investments, we have a technologically advanced high capacity network that provides extensive coverage across Portugal. As of December 31, 2011, our digital network had 4,909 GSM base stations, including 203 base stations added during 2011, and 3,778 UMTS B nodes, including 100 B nodes added during 2011. As of December 31, 2011, these GSM base stations covered more than 95% of Portugal and 98% of the Portuguese population, and the UMTS B nodes covered approximately 68% of Portugal and 93% of the Portuguese population, including every municipality with over 5,000 inhabitants.

In addition, through roaming agreements, our subscribers can make and receive mobile calls throughout Europe and in many other countries around the world. Roaming agreements between operators allow their subscribers to make and receive voice calls automatically, send and receive data, or access other services when traveling outside the geographical coverage area of the home network, by using a visited network. As of the end of 2011, we had entered into GSM roaming agreements with a total of 618 operators (in 229 countries) and 275 UMTS roaming agreements (in 122 countries).

Personal Services

Our products and services include:

• a variety of voice and data tariff plans, both prepaid and postpaid;
• a portfolio of approximately 30 smartphones, including exclusive handsets, with the capability to use an array of value-added and convergent services (mobile TV, music on demand, social network aggregator, etc); and
• mobile broadband offers of up to 100Mbps speed, using 4G technology and offering free access to our leading national Wi-Fi nework.

We were the first operator in the world to offer prepaid services, and our prepaid and discount products remain popular. As of December 31, 2011, approximately 82.1% of our subscribers were using prepaid products.

We continuously invest in new services, and the services we have launched in recent years include (1) ''Music Box'', an integrated service for mobile phones, PCs and television that provides access to a catalog of millions of music tracks, (2) our application store, offering sports, news, entertainment, games, books and utility applications, which builds upon the presence of our online portal Sapo and partnerships with third parties, (3) ''Meo Mobile'', which makes available 50 TV channels, in areas such as information, sports, entertainment, children and other, on the mobile phone, (4) ''Pond'', an aggregation service that enables access to multiple personal accounts and aggregation of social network accounts and (5) our ''internetnotelemovel ´ '' service, which offers internet access on smartphones and access to our mobile portal.

In 2011, we accomplished significant progress in a new commercial offer characterized by the launch of the ''e nunca mais acaba'' and of the ''unlimited'' tariff plans, which were targeted at upselling mobile Internet, leveraging the increased popularity of smartphones and promoting the use of voice and value-added services. In particular, the ''e nunca mais acaba'' tariff plan showed solid growth in 2011, reaching 755 thousand customers by the end of the year. We also introduced changes in roaming tariff structures. In August 2011, we launched two new daily tariff plans for ''internetnotelemovel'' aimed at increasing the number of customers that use mobile internet while ´ roaming. In addition, we launched convergent offers aimed at reducing churn. These offers include ''Pontos TMN a dobrar,'' which doubles the benefits (air miles) attributed to those customers who are simultaneously customers of TMN and Meo. Finally, we launched a new offering in March 2012 targeted at the kids segment and positioned upon the concept of security and cost control, thus addressing the main concerns of parents in choosing the first mobile phone for their children.

In March 2012, we unveiled our 4G strategy by launching a mobile broadband offer which allows speeds of up to 100Mbps, includes access to live TV channels (through Meo Mobile), access to a music streaming service (MusicBox) and the ability to share traffic among various devices, including PC, wireless dongles, tablets and smartphones. In the end of April 2012, we expect our 4G service to be available to approximately 80% of the Portuguese population. This coverage is expected to increase to 90% by the end of 2012. We market our 4G mobile broadband services through the TMN 4G and Meo 4G brands, aiming at leveraging on the various attributes and strengths of each brand. The offers will have a speed from 50Mbps to 100Mbps and monthly retail prices starting at A49.99 and including the MusicBox service. TMN 4G or Meo 4G customers that are also Meo customers will have free access to 50 live TV channels through the Meo Go service.

Also in March 2012, as part of a strategic focus on innovation, we announced a new mobile payment service under the brand ''TMN Wallet'' which allows customers to pay for small purchases through any of the following means: (1) SMS messages, (2) USSD, (3) NFC—Near Field Communication and (4) QR code. This service is available for all types of mobile phones, including smartphones, and is currently undergoing a trial period.

Components of Revenue

Our revenues from personal services are derived from the following components:

• Service revenues, which are the revenues we generate from providing mobile voice telecommunications services, mobile broadband access and other mobile services. These service revenues can be further broken down into:
  • Customer revenues, which are revenues we receive directly from our customers and consist primarily of traffic charges, though we also derive a small amount of revenue from subscription charges; and
  • Interconnection revenues, which are the revenues we receive from other telecommunications providers when their customers make calls or otherwise connect to our network from fixed lines or mobile devices.
• Sales and other revenues, which are revenues from the sale of mobile phones and related equipment.

We believe that mobile services in Portugal are priced lower than the European average and are among the lowest in Europe. Fixed-to-mobile and mobile-to-mobile interconnection charges are regulated by ANACOM and have a significant impact on our business. Since 2005, when ANACOM declared all mobile operators to have significant market power in call termination in mobile networks market, ANACOM has accordingly imposed price controls on interconnection rates for the termination of calls on mobile networks. Interconnection rates have been reduced steadily since then. These reductions have had, and are expected to continue to have, a significant impact on our interconnection revenues and consequently its cash flows and earnings.

In May 2010, ANACOM imposed a glide path that reduced mobile termination rates by A0.005 per quarter, reaching A0.035 in August 2011. In April 2011, based on an EC Recommendation on fixed and mobile termination rates of May 2009, which required national regulatory authorities to develop bottom-up pure long-run incremental cost (''LRIC'') models to regulate mobile termination rates, ANACOM held a consultation on the definition of such a cost model to regulate mobile termination rates. In March 2012, ANACOM issued a final decision on a new glide path, according to which mobile termination rates will decrease in four steps to (1) A0.0277 as of Abril 30, 2012, (2) A0.0227 as of June 30, 2012, (3) A0.0177 as of September 30, 2012 and (4) A0.0127 as of December 31, 2012.

Suppliers

We do not manufacture handsets, but we have agreements with a number of manufacturers to sell handsets in Portugal, including Nokia, Samsung, ZTE, Huawei, Apple, Sony Ericsson, LG and RIM. In addition, Nokia Siemens Networks Portugal and Huawei Technology Portugal were material suppliers of mobile network equipment and services in 2011.

Marketing

We market our personal services primarily using our TMN brand and the trademarks and servicemarks of our individual products and services. We market personal services through more than 3,190 points of sale, including our sales force, retail shops, supermarket chains and independent dealers.

Over the last few years, we have sought to expand our subscriber base for personal services through increased advertising and the use of our own distribution network. In recent years, we have focused on encouraging the use of mobile services by young people through SMS incentive packages.

We also have a low-cost brand, Uzo, that targets low-cost subscribers and uses our GSM network. Uzo offers a very simple service to its customers with no obligatory recharges and one tariff for voice calls and SMSs to all networks. Uzo focuses primarily on selling SIM cards and low-cost mobile phones to its customers. Uzo's products and services are offered through the Internet, Uzo's call centers (which are separate from TMN's call centers) and independent news stands and shops located throughout Portugal.

Enterprise Customers

We provide enterprise services to corporate, small and medium enterprise (''SME'') and small office/home office (''SoHo'') customers that need diversified telecommunications solutions and integration with IT services. We have developed a full range of telecommunications services for businesses, and we integrate these services to provide our customers with service packages. By combining our communications capabilities with our software-based integrated systems and applications, we offer integrated voice, data and image solutions, virtual private networks, convergence solutions, consultancy and outsourcing. We believe we are the primary service provider in Portugal capable of offering customers a full range of integrated and customized services.

We are maintaining our focus on the developing convergent offers for SMEs for specific sectors, such as ''Office Box Cafes e Restaurantes'' (for coffee shops and restaurants) and ´ ''Office Box Medicos e Cl ´ ´ınicas'' (for physicians and medical practices).

The provision of services to our corporate customers is guided by the following strategic objectives: (1) maximize value from traditional telecommunications services by upselling additional services, including fixed-mobile convergence on FTTH, VPN, LAN management and video services, (2) IT transformation accelerated by cloud computing, where we aim to build upon partnerships with key suppliers to enable business process transformation and cost reductions to our corporate customers, with a special focus on ''system on a chip,'' or SOC, based security solutions, (3) capture mobile data growth through LTE-based solutions and new machine-to-machine projects, (4) use specialization to achieve gains from scale, including by focusing on outsourcing and BPO to improve productivity and (5) introduce a business consulting approach in order to extend the services provided to corporations to video, multiscreen and other convergent services.

We also provide reporting services targeted to special customers to control service level agreements and the overall performance of the network. In addition, we provide outsourced corporate network services for our customers. In the SME/SoHo customer segment, we aim to integrate our service offerings, including bundling fixed and mobile and voice and data offers with access to subsidized equipment (PCs, PBX, smartphones and tablets), while at the same time making available vertical solutions for specific sectors, such as our such as our ''Office Box Cafes e Restaurantes'' product (for ´ coffee shops and restaurants) and our ''Office Box Medicos e Cl ´ ´ınicas'' product (for physicians and medical practices). In the SME segment, our main strategic priority during 2011 was to increase our commercial proactivity, focusing on the growth of core products.

During 2011, we also continued to invest significantly in our cloud computing offering both for corporates and SMEs, making available structured offers, branded SmartcloudPT, that include infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS).

Networks

We provide services over the largest IP/MPLS backbone in Portugal. We have points of presence in all major cities throughout Portugal, and we link our network to our customers' premises through switches and access points that we own. This broadband data transmission network provides high capacity, flexibility and security and can progressively incorporate current voice and data infrastructures at lower costs than alternative networks. We also provide high speed Internet access through ADSL and Ethernet.

Partnerships and Suppliers

We have a strong and competitive position in the development of information technology solutions where communications are an integral part of the services provided. To reinforce our position as a leader in this area, we are pursuing a partnership strategy with the primary information technology suppliers in the market, particularly software and hardware providers.

We offer services in partnership with leading operators and service providers such as Telefonica, ´ British Telecom and Orange. We use systems and networks in partnership with Siemens, Alcatel, Cisco Systems, Motorola, Nortel Networks, Critical Software and Matra/EADS Telecom.

We have pursued our partnerships with Cisco and other leading companies in the industry with a view towards developing, implementing and continuously launching new services in cloud computing, which include virtual services, security, application and unified communications, intended to help companies adopt more efficient business models by reducing costs related to information technology.

In December 2010, we signed a collaboration agreement with SingTel, the Singapore telecommunications company. This agreement provides for: (1) sharing best practices and benchmarks in operational and commercial areas related to fiber and IPTV, (2) cooperation in research and development, including the joint creation of multiplatform applications and solutions, (3) development of innovative applications for fixed and mobile high speed networks, (4) leveraging economies of scale through joint procurement and (5) promotion of internship programs allowing the employees of both companies to share best practices and experiences.

Data Centers and Systems Integration Services

To support our services and to respond to the increasing demand of e-business integrators, we have opened Data Centers in Lisbon and Oporto as well as in Funchal and Ponta Delgada, in the Madeira and Azores islands, respectively. These facilities allow us to provide services, such as co-location, sophisticated web hosting, ISP services, data storage, disaster recovery and ASP services.

In February 2011, we announced the construction of a new Data Center in Covilha, Portugal, ˜ which will be a 75,000-square meter facility with installation capacity for over 50,000 servers. The Data Center has been designed to be a world reference in energy efficiency with a projected annual average power usage effectiveness (PUE) below 1.25. The Data Center will be supported by a redundant fiber network to connect it to major global communications networks and is expected to focus on providing large processing and data storage capacity to customers inside and outside Portugal based on cloud computing services under the brand SmartCloudPT. We expect that the Data Center will become operational in 2012.

Components of Revenue

Our revenues from enterprise services include:

• traffic charges for voice and data services;
• outsourcing or management services and fees for business process outsourcing (BPO); and
• consultancy fees.

Profits and losses related to services provided to Enterprise customers were previously recorded under both the wireline and mobile segments.

Wholesale and Other Services

In addition to the services we provide in our primary customer categories of residential services, personal services and enterprise services, we provide wholesale services and generate a small amount of revenue from other activities, such as the production and distribution of telephone directories. We report revenues from these services and products, together with eliminations in consolidation for transactions among our residential, personal and enterprise customers, as ''Wholesale, other and eliminations'' in our financial statements. Generally, these other services were previously recorded under our wireline segment.

Wholesale Services

Wholesale services provided A466.5 million, A491.3 million and A495.4 million to our wireline operating revenues in 2011, 2010 and 2009, respectively. Our wholesale services consist of:

• domestic and international interconnection telephone services (including capacity-based domestic interconnection) that we provide to other telecommunications service providers in Portugal;
• provision of carrier pre-selection and number portability;
• leasing of domestic and international lines to other telecommunications service providers and Portuguese cable television operators;
• provision of ADSL (including ''naked'' DSL) on a wholesale basis to other ISPs;
• provision of unbundled access (including shared access) to metallic loops and sub-loops to provide broadband and voice services to other telecommunications operators in Portugal;
• provision of wholesale line rental to other telecommunications service providers in Portugal;
• provision of co-location services and access to ducts, poles and associated facilities to other telecommunications operators in Portugal;
• transmission of television and radio signals for major broadcast television companies in Portugal;
• narrowband Internet access origination services, which we provide to ISPs;
• international carrier services (transport, transit and/or termination) for international switched traffic; and
• other services provided to telecommunications service providers and operators, such as IP international connectivity.

Interconnection Traffic. Interconnection traffic comprised about 41% of our wholesale business in terms of revenues in 2011. The service providers who purchase interconnection services include fixed and mobile network operators, voice and data communications service providers, ISPs, value-added service providers and service providers whose international calls are terminated on or carried by our network. Providing interconnection services means allowing third parties to connect their networks to our network, and vice versa. We have interconnection rates namely for call termination, call origination, transits and international interconnection.

Interconnection Prices. Domestic interconnection revenue per minute for calls terminated on our network declined by 8% in nominal terms in 2011 compared to 2010 and by 6% in 2010 compared to 2009. International interconnection revenue per minute for wholesale operators' outgoing traffic decreased by 20% in nominal terms in 2011 compared to 2010 and by 13% in 2010 compared with 2009. In accordance with EU and Portuguese regulations, our national interconnection prices are cost-oriented (with costs audited by ANACOM) plus a margin.

Leased Lines. We lease lines to other telecommunications providers for fixed, mobile and data communications services, including our own subsidiaries and competitors. Leased line services involve making a permanent point-to-point connection with dedicated and transparent capacity between two geographically separate points. We offer both national terminating segments and trunk segments at the wholesale level. We also lease international circuits to national and international operators to allow them to complete their circuits (often circuits that pass through Portugal linking other countries), and we sell segments of international circuits to international operators. The three current mobile telephone operators in Portugal, which include our subsidiary TMN, Vodafone Portugal and Optimus, are among our wireline business's largest leased line customers.

Telephone Directories

We subcontract to Paginas Amarelas (an affiliated company 25% owned by us) for the publication ´ and distribution of telephone directories throughout Portugal in return for an annual payment of approximately 78% of its gross revenues from the sale of advertising space. Our revenues from our directories business amounted to A45.9 million, A66.2 million and A80.1 million in 2011, 2010 and 2009, respectively.

DTT Services

In 2008, pursuant to the European Commission's proposal to cease analog transmissions in all member states by 2012, ANACOM launched a public tender to grant the rights of use of frequencies allocated to the transmission of digital terrestrial television (''DTT'') signals. Following a public tender launched by ANACOM in 2008, our subsidiary PT Comunica¸coes was granted the frequency usage ˜ rights for DTT associated with the transport of the signal of free-to-air television programs (the RTP, SIC and TVI broadcast channels), the so-called ''Multiplex A'' or ''Mux A.'' In 2009, the Portuguese media regulatory authority (Entidade Reguladora para a Comunica¸cao Social ˜ , or ''ERC'') notified us of its final decision to grant us a license to act as a TV distribution operator.

We launched DTT (using DVB-T, or terrestrial signals) in 2009, initially covering 29 municipalities and over 40% of the population. By the end of 2011 we achieved 100% population coverage (approximately. 90% using DVB-T and 10% using DVB-H (satellite)).

The switch-off of the analog television network in Portugal occurred on April 26, 2012.

DTT only encompasses broadcasting of free-to-air television programs, while our Meo offer comprises both free-to-air television programs, as well as Pay-TV channels, being provided over FTTH, ADSL and DTH technologies.

Other Revenues

We also record revenue from providing public pay telephone services, advertising on www.sapo.pt, our Internet portal, contractual penalties imposed on customers and rentals of equipment and other infrastructure.

Brazilian Operations (Oi)

Overview

In 2011, we entered into a strategic partnership with Oi, Brazil's largest telecommunications group, and we hold a significant interest in Oi. Under the governance arrangements of Oi reflected in a series of shareholder agreements described below, we have a significant role in determining, among other things, the operational strategy of Oi.

Oi is one of the largest integrated telecommunications service provider in Brazil, based on information available from ANATEL regarding the total number of Brasil Telecom's and TNL's fixed lines in service and mobile subscribers as of December 31, 2011, and the only telecommunications services provider offering ''quadruple play'' services in Brazil. Oi is the largest telecommunications provider in both Region I and Region II in Brazil, based on information available from ANATEL and other publicly available information regarding Oi's and TNL's revenues and customers as of and for the year ended December 31, 2011. Oi has also been offering mobile telecommunication services in Region III since October 2008. Oi's services include:

• Residential services, which include:
  • local fixed-line services, primarily in Regions I and II, but also in Region III, including installation, monthly subscription, metered services, collect calls and supplemental local services;

Residential Services

Oi's traditional fixed-line telecommunications business in Regions I and II includes local and long-distance services, network usage services (interconnection) and public telephones, in accordance with the concessions and authorizations granted to it by ANATEL. Oi is one of the largest fixed-line telecommunications companies in South America in terms of total number of lines in service as of December 31, 2011. Oi is the principal fixed-line telecommunication service provider in Region I and Region II, based on its 12.0 million and 6.8 million fixed lines in service in Region I and Region II, respectively, as of December 31, 2011, with market shares of 72.7% and 66.4%, respectively, of the total fixed lines in service in these regions as of December 31, 2011, based on information available from ANATEL.

Local Fixed-Line Services

As of December 31, 2011, Oi had approximately 12.0 million local fixed-line customers in Region I and approximately 6.8 million local fixed-line customers in Region II. Although Oi continues to assess its strategic plans with regard to providing such services in Region III, Oi does not currently plan to offer local fixed-line services to residential customers in Region III due to the size of the investment that would be required. Local fixed-line services include installation, monthly subscription, metered services, collect calls and supplemental local services. Metered services include local calls that originate and terminate within a single local area.

Under Oi'sconcession agreements, it is required to offer two local fixed-line plans to users: the Basic Plan per Minute (Plano Basico de Minutos ´ ) and the Mandatory Alternative Service Plan (Plano Alternativo de Servi¸cos de Oferta Obrigatoria ´ ), each of which includes installation charges, monthly subscription charges, and charges for local minutes. As of December 31, 2011, 19.8% of the aggregate number of fixed-line customers of Oi subscribed to the Basic Plan per Minute or the Mandatory Alternative Service Plan. In addition to the Basic Plan per Minute and the Mandatory Alternative Service Plan, Oi offers a variety of alternative fixed-line plans that are designed to meet its customers' usage profiles. As of December 31, 2011, 80.2% of the aggregate number of fixed-line customers of Oi subscribed to alternative plans.

Long-Distance Services

For each long-distance call, whether originated from a fixed-line telephone or a mobile handset, a caller chooses its preferred long-distance carrier by dialing such carrier's long-distance carrier selection code. The caller pays the long-distance service provider for the call and the long-distance service provider pays interconnection fees to the service providers on whose fixed-line or mobile networks the call originated and terminated. Oi's domestic and international long-distance services consist primarily of calls originated in Region I and Region II, and its customer base consists of residential and business subscribers.

Oi provides domestic long-distance services for calls originating from Region I and Region II through its network facilities in Sao Paulo, Rio de Janeiro and Belo Horizonte and through ˜ interconnection agreements, mainly with Telecomunica¸coes de S ˜ ao Paulo S.A. (''Telesp'') in Region III, ˜ that permit it to interconnect directly with their local fixed-line networks. Oi provides international long-distance services originating from Region I and Region II through agreements to interconnect its network with those of the main telecommunication service providers worldwide.

Oi also provides mobile long-distance services originating from Region I and Region II through network facilities and through interconnection agreements with Telesp in Region III and each of the other principal mobile services providers operating in Brazil that permit it to interconnect directly with their local fixed-line and mobile networks. Oi provides international long-distance services originating or terminating on its customers' mobile telephones through agreements to interconnect its network with those of the main telecommunication service providers worldwide. Oi also uses its submarine fiber optic network to transport international mobile long-distance calls.

Data Transmission Services

Oi offers a variety of high-speed data transmission services in Regions I and II, including services offered by its subsidiaries BrT Servi¸cos de Internet S.A. and Brasil Telecom Comunica¸cao˜ Multim´ıdia ltda. Oi also operates a fiber optic cable system that connects the United States, Bermuda, Brazil, Venezuela and Colombia through its subsidiaries Brasil Telecom Cabos Submarinos Ltda., Brasil Telecom Subsea Cable System (Bermuda) Ltd., Brasil Telecom of America Inc. and Brasil Telecom de Venezuela S.A. Oi's broadband services, primarily utilizing ADSL technology, are marketed under the brand name ''Oi Velox.'' As of December 31, 2011, Oi offered broadband services in 2,833 municipalities in Region I and 1,848 municipalities in Region II. As of December 31, 2011, Oi had 4.9 million ADSL subscribers in Regions I and II, representing 26.1% of its fixed lines in service at that date. Additionally, Oi provides voice and data services to corporate clients throughout Brazil.

Oi's network supports ADSL2+, VDSL2, or very-high-bitrate digital subscriber line, and FTTx technologies. ADSL2+ is a data communications technology that allows data transmission at speeds of up to 24 Mbps downstream and 1 Mbps upstream, which is much faster than data transmission through conventional ADSL. ADSL2+ permits Oi to offer a wider range of services than ADSL, including IP TV. VDSL2 is a DSL technology providing faster data transmission, up to 100 Mbps (downstream and upstream), permitting Oi to support high bandwidth applications such as HDTV, Voice over Internet Protocol, or VoIP, and broadband internet access, over a single connection. As of December 31, 2011, approximately 85% of Oi's fixed-line network had been updated to support ADSL2+ or VDSL2. FTTx, or Fiber to the x, is a term for broadband network architecture that uses optical fiber to replace all or part of the usual metal local loop used for last mile telecommunications.

Network Usage Services (Interconnection Services)

All telecommunication services providers in Brazil are required, if technically feasible, to make their networks available for interconnection on a non-discriminatory basis whenever a request is made by another telecommunication services provider. Interconnection permits a call originated on the network of a requesting local fixed-line, mobile or long-distance service provider's network to be terminated on the local fixed-line or mobile services network of the other provider.

Oi is authorized to charge for the use of its local fixed-line network on a per-minute basis for (1) all calls terminated on our local fixed-line networks in Regions I and II that originate on the networks of other local fixed-line, mobile and long-distance service providers, and (2) all long-distance calls originated on Oi's local fixed-line networks in Regions I and II that are carried by other long-distance service providers. Conversely, other local fixed-line service providers charge Oi interconnection fees (1) to terminate calls on their local fixed-line networks that are originated on Oi's local fixed-line, mobile or long-distance networks, and (2) for long-distance calls originated on their local fixed-line networks that are carried by Oi's long-distance network. In addition, Oi charges network usage fees to long-distance service providers and operators of trunking services that connect switching stations to its local fixed-line networks.

Oi is authorized to charge for the use of its long-distance network on a per-minute basis for all calls that travel through a portion of its long-distance networks for which the caller has not selected Oi as the long-distance provider. Conversely, other long-distance service providers charge Oi interconnection fees on a per-minute basis for all calls that travel through a portion of their long-distance networks for which the caller has selected Oi as the long-distance provider.

Other Services

Long-distance and mobile services providers may avoid paying long-distance network usage charges to Oi by establishing an interconnection to its local fixed-line networks. In order to retain these customers of its long-distance services, Oi offers a long-distance usage service, called national

transportation, under which Oi provides discounts to its long-distance network usage fees based on the volume of traffic and geographic distribution of calls generated by a long-distance or mobile services provider. Oi also offers international telecommunications service providers the option to terminate their Brazilian inbound traffic through its network, as an alternative to Embratel and Intelig Telecomunica¸coes Ltda. (''Intelig''). Oi charges international telecommunication service providers a ˜ per-minute rate, based on whether a call terminates on a fixed-line or mobile telephone and the location of the local area in which the call terminates.

Oi owns and operates public telephones throughout Region I and Region II. As of December 31, 2011, Oi had approximately 771,300 public telephones in service, all of which are operated by prepaid cards.

Personal Services

Oi offers mobile telecommunication services throughout Brazil. Based on its 28.3 million, 8.6 million and 8.6 million mobile subscribers in Regions I, II and III, respectively, as of December 31, 2011, we believe that Oi is one of the principal mobile telecommunications service providers in each service region. Based on information available from ANATEL, as of December 31, 2011 Oi's market share was 23.2% in Region I, 14.2% in Region II and 14.5% in Region III, respectively, of the total number of mobile subscribers in these regions. As of December 31, 2011, 83.0% of the customers of Oi subscribed to prepaid plans and 17.0% subscribed to postpaid plans.

Prepaid customers activate their cellular numbers through the purchase and installation of a SIM card in their mobile telephones. Oi's prepaid customers are able to add credits to their accounts through the purchase of prepaid cards at prices that vary based on the number of minutes available, or through the purchase of additional credits over the phone that can be charged to the customer's credit card or included on their bill for fixed-line services. These credits are valid for a fixed period of time following activation.

Postpaid customers pay a monthly subscription fee and are billed on a monthly basis for services provided during the previous month. Postpaid plans include mailbox, caller ID, conference call capability, call forwarding, calls on hold and special services for customers with advanced mobile handset models.

The services we offer our mobile telecommunications customers include a number of value-added services, including voicemail, caller ID and other services, such as personalization (video downloads, games and ring tones), SMS subscription services (e.g., horoscopes and soccer team information), chat services, mobile television, location-based services and applications (mobile banking, mobile search, email and instant messaging).

Oi has roaming agreements with Companhia de Telecomunica¸coes do Brasil Central (''CTBC'') ˜ and Sercomtel S.A. Telecomunica¸coes (''Sercomtel''), providing its customers with automatic access to ˜ roaming services when traveling in areas of Brazil outside its coverage area where mobile telecommunication services are available on the GSM standard. Oi generates revenues from roaming when one of its mobile subscribers receives a call while at a location outside the sector that includes their home registration area. In addition, Oi generates revenues when a subscriber of another mobile services provider places a call from a location that is outside the coverage area of its mobile services provider and the call is originated on Oi's mobile networks. Conversely, when one of Oi's mobile subscribers places a call from outside of Brazil, Oi pays the applicable roaming rate to the mobile services provider on whose network the call originated.

Enterprise Services

Oi provides fixed-line and mobile voice and data transmission services of the types described above to corporate customers and small and medium businesses.

In addition, Oi provides a variety of customized, high-speed data transmission services through various technologies and means of access to other telecommunication services providers, ISPs and corporate customers. Its data transmission services include interconnection between local area networks at data transmission speeds of 34 Mbps, 155 Mbps and 1 Gbps, videoconferencing, video/image transmission and multimedia applications. Oi's principal commercial data transmission services are:

• Industrial Exploitation of Dedicated Lines (Explora¸cao Industrial de Linha Dedicada ˜ ) (''EILD''), under which Oi leases trunk lines to other telecommunication services providers, primarily mobile services providers, which use these trunk lines to link their radio base stations to their switching centers;
• Dedicated Line Services (Servi¸cos de Linhas Dedicadas) (''SLD''), under which Oi leases dedicated lines to other telecommunications services providers, ISPs and corporate customers for use in private networks that link different corporate websites;

Call Centers

In 2007, Brasil Telecom consolidated its call center structure by merging 30 pre-existing sites into five sites (Goiania, Campo Grande, Florian ˆ opolis, Bras ´ ´ılia and Curitiba). Oi has improved its customer relationship management system, which integrates its systems and provides a database of information for each customer in order to provide better service and identify sales opportunities during each contact Oi has with its customers.

In 2009, Telemar, a subsidiary of Oi S.A. (then Brasil Telecom), restructured its call center arrangements with Contax, relocating several of its call centers and reducing the number of call centers from 12 to nine. As part of this revision, Telemar invested in automated platforms that permit its prepaid customers to add prepaid minutes to their subscriptions through an automated process.

Developments in 2011

Residential Services

In the fourth quarter of 2011, Oi achieved its best performance since the second quarter of 2010. This improvement was due mainly to the restructuring of fixed tariff plans in the second half of 2011. These plans provide incentives for the use of fixed line by expanding its benefits, including (1) free minutes for local fixed calls, (2) free minutes for national long distance fixed calls using Oi's long distance codes, (3) free minutes for local calls to Oi Mobile and (4) digital calling services.

Oi continues to seek to provide attractive commercial conditions for existing and new customers to subscribe to Oi Velox, Oi's broadband internet brand, aiming to strengthen customer loyalty and increase penetration of its services in its customer base. Oi continued to invest in the quality of its fixed broadband service, which offers speeds of up to 20Mbps for prices starting at R\$39.90 per month. Oi also increased the broadband speeds it provides to customers, and in 2011, the average fixed broadband speed stood at 2.5Mbps in fourth quarter, compared to 2.33Mbps at the end of the third quarter, 2.13Mbps at the end of the second quarter and 1.91Mbps at the end of the first quarter. In addition, by the end of 2011, 24% of the Oi Velox customer base had services with speeds of more than 5Mbps, of which 47% had speeds higher than 10Mbps. Moreover, at the end of 2011 Oi launched a new convergent offer with competitive prices, Oi Conta Total, which included mobile broadband and Velox 3G.

In November 2011, Oi launched Oi Internet Total, a broadband service, which allows internet access with more mobility, at home with Oi Velox or outside with 3G or Wi-Fi networks. In September 2011, Oi initiated a partnership with the Brazilian government for the implementation of the Brazilian national broadband plan (Plano Nacional de Banda Larga), aiming at increasing the penetration of broadband in Brazil.

During 2011, Oi expanded coverage, reaching 450 cities by the end of the year. Oi aims to cover 4,800 cities by 2014. During 2011, Oi also focused on strengthening Oi TV by launching new offers and implementing operational improvements. In October 2011, Oi launched 21 new offers aimed at increasing the penetration of TV plans with premium movie channels, including Telecine and HBO. In the fourth quarter of 2011, Oi launched a new service in Rio de Janeiro, including the GloboSat and TV Globo channels. The TV Globo channel was also included in 189 municipalities in five different states. During the fourth quarter of 2011, Oi TV expanded its offer to an additional 19 cities, covering 24 states by the end of 2011. In the residential customer category, Oi had approximately 13.1 million unique residential customers as of December 31, 2011.

Personal Services

In 2011, Oi's personal customer segment had approximately 43,264 thousand mobile customers, representing an increase of 14.6% from previous year, with net additions of 5.5 million. In 2011, Oi had approximately 45.5 million mobile customers, representing an increase of 15.8% from previous year, with net additions of 6.2 million. Gross additions in 2011 were 24.7 million, while the fourth quarter of 2011 had additions of 6.5 million. The increase in the period is primarily explained by the decision to adopt more restrictive criteria for recording active customers in the customer base, particularly in the prepaid segment, aiming at minimizing regulatory fees and improving Oi's profitability.

During the fourth quarter of 2011, in the postpaid segment, Oi has launched several initiatives aimed at increasing customer growth, such as (1) an offer simplification process, (2) restructuring of distribution channels and (3) price repositioning. As a result, 42% of net additions in 2011 were achieved in the fourth quarter of 2011. Further, during the fourth quarter of 2011, as a complement to the new offers launched during the third quarter of 2011, Oi Dados and Oi Velox 3G, Oi launched a new offer that allows free access to Oi's Wi-Fi network and to Vex, the largest Brazilian Wi-Fi network acquired by Oi, as well as a free trial of two months of Oi Radio.

During 2011, in the prepaid segment, Oi continued to market the new offers launched at the end of 2010 that allow daily bonuses dependent on the amount of the recharges and that may be used for on-net and off-net SMS, local calls to fixed lines and Oi Mobile and long distance calls using Oi's long distance codes to Oi fixed and mobile customers. In the fourth quarter of 2011, as a complement to these new offers, Oi launched SMS packages allowing customers to send on-net and off-net messages with a discount of up to 88%. To increase mobile internet access in the handset in the prepaid segment, Oi launched 3 new data packages (1) a daily offer, with 5MB at R\$0.50, (2) a weekly offer, with 20MB, at R\$2.99 and (3) a monthly offer, with 50MB at R\$9.99.

During 2011, Oi launched several initiatives to improve operational performance and increase customer loyalty. Specifically, in December 2011, Oi opened 60 new corporate owned stores, aiming at strengthening its distribution channels, Oi also created new regional commercial structures to improve its commercial flexibility and effectiveness and initiated smartphone subsidization for postpaid mobile customers.

During 2011, Oi has been increasing its minimum recharge in certain regions, aiming at improving profitability, while at the same time offering improved bonuses to maintain the attractiveness of commercial offers. As a result of these initiatives and stronger commercial competitiveness, Oi's personal segment base grew by 14.6% as compared to previous year. In 2011 Oi had approximately 38 million prepaid customers, representing 87.8% of Oi's personal segment base, while postpaid

customers were at approximately 3.1 million. Oi Controle customers also grew by 13.3% to over 2.1 million.

Enterprise Services

Anticipating growth opportunities among corporate customers, Oi established a new business area focused on enterprises. In February 2012, Oi launched Smart Cloud Oi, becoming the first operator in Brazil to launch a cloud computing offer for corporate customers. This new service offers customised infrastructure and storage capacity and access to advanced data centers. It also makes available end-to-end solutions, including data networks, ensuring high performance and data security. In 2011, Oi had approximately 7.8 million enterprise customers, an increase of 10.6% from previous year.

Developments in 2012

On February 6, 2012, the board of directors of Brasil Telecom approved the issuance of non-convertible debentures in the amount of R\$2,000 million. In February 2012, Brasil Telecom issued US\$1,500 million senior notes due February 2022 that bear interest at a 5.75% per annum.

Strategic Partnership with Oi

Background and History

On July 28, 2010, we reached an agreement with Telefonica to sell our 50% interest in ´ Brasilcel N.V., a joint venture that held our interest in Vivo, to Telefonica. The sale was concluded on ´ September 27, 2010. We reflect Vivo in our statements of income and cash flows for periods prior to September 27, 2010 as a discontinued operation. As of December 31, 2010 and 2011, none of the assets or liabilities of Vivo are reflected on our balance sheet.

On July 28, 2010, we also entered into a letter of intent with AG Telecom Participa¸coes S.A. (''AG ˜ Telecom'') and LF Tel S.A. (''LF Tel''), companies that are part of the controlling group of Brasil Telecom, to establish the main terms that would serve as a framework for the negotiation of our strategic partnership with Oi.

On January 25, 2011, Portugal Telecom and our subsidiary Bratel Brasil S.A. (''Bratel'') entered into agreements with TmarPart, AG Telecom, Luxemburgo Participa¸coes S.A. (a subsidiary of AG ˜ Telecom, that has since merged with and into AG Telecom and is referred to, together with AG Telecom, as ''AG''), LF Tel, BNDES Participa¸coes S.A. (''BNDESPar''), Funda¸ ˜ cao Atl ˜ antico de ˆ Seguridade Social (''FASS''), Caixa de Previdencia dos Funcion ˆ arios do Banco do Brasil—PREVI ´ (''PREVI''), Funda¸cao Petrobr ˜ as de Seguridade Social—PETROS, (''PETROS'') and Funda¸ ´ cao dos ˜ Economiarios Federais—FUNCEF (''FUNCEF'') to implement the strategic partnership with the Oi ´ Group.

On March 28, 2011:

• Bratel acquired from BNDESPar, PREVI, PETROS and FUNCEF an aggregate of 261,631,051 common shares issued by TmarPart, representing 9.6% of TmarPart's total outstanding common shares;
• Bratel acquired from Andrade Gutierrez Telecomunica¸coes Ltda. and La Fonte Telecom S.A. a ˜ 35% interest in each of Pasa Participa¸coes S.A. and EDSP75 Participa¸ ˜ coes S.A., respectively, ˜ holding companies that own 100% of the share capital of AG Telecom and LF Tel;
• TmarPart increased its share capital through the issuance of 186,664,449 common shares, in which transaction (1) Bratel subscribed for an aggregate of 91,225,537 common shares issued by TmarPart, representing 3.1% of TmarPart's total outstanding common shares, (2) AG Telecom and its subsidiary Luxemburgo subscribed for an aggregate of 36,784,491 common shares issued

by TmarPart, representing 1.3% of TmarPart's total outstanding common shares, (3) LF Tel subscribed for an aggregate of 36,784,491 common shares issued by TmarPart, representing 1.3% of TmarPart's total outstanding common shares, and (4) FASS acquired an aggregate of 21,869,930 common shares issued by TmarPart, representing 0.7% of TmarPart's total outstanding common shares;

• TNL increased its share capital through the issuance of 56,417,086 common shares at an issue price of R\$38.5462 per share and of 28,409,175 preferred shares at an issue price of R\$28.2634 per share. The aggregate proceeds received by TNL from this capital increase amounted to R\$2,978 million. In this capital increase, TmarPart and its wholly-owned subsidiary Valverde Participa¸coes S.A. subscribed for 35,309,502 common shares issued by TNL, and Bratel acquired ˜ an aggregate of 20,752,270 common shares and 28,298,549 preferred shares issued by TNL. Following this capital increase, TmarPart owned, and owns as of the date hereof, 22.4% of TNL's total share capital, including 50.5% of its voting share capital, and Bratel owned, and owns as of the date hereof, an aggregate 10.5% of TNL's total share capital, or 11.3% of its voting share capital; and
• Telemar increased its share capital through the issuance of 46,969,121 common shares at an issue price of R\$63.7038 per share and 58,696,856 class A preferred shares at an issue price of R\$50.7010 per share. The aggregate proceeds received by Telemar from such capital increase amounted to R\$5,969 million, of which R\$4,624 million represented the purchase price for the shares issued by Telemar subscribed for by TNL. In this capital increase, TNL acquired 46,743,149 common shares issued by Telemar, and Bratel acquired an aggregate of 32,475,534 class A preferred shares issued by Telemar. Following this capital increase, TNL owned, and owns as of the date hereof, 70.4% of Telemar's total share capital, including 98.0% of its voting share capital, and Bratel owned, and owns as of the date hereof, an aggregate of 9.4% of Telemar's total share capital.

Following the consummation of the transactions described above, we held a 25.3% economic interest in Telemar on a consolidated basis. We held this interest through (1) an indirect 35% interest in AG Telecom, (2) an indirect 35% interest in LF Tel, (3) a 12.1% direct interest in TmarPart, (4) a 10.5% direct interest in TNL and (5) a 9.4% direct interest in Telemar. Given our economic interest and our rights to participate in the management of Oi as described below, since April 1, 2011, we have proportionally consolidated 25.6% of TmarPart in our consolidated financial statements, which, in turn, fully consolidates TNL and Telemar.

Reorganization of the Oi Companies

On May 24, 2011, TmarPart publicly announced a proposed corporate reorganization (the ''Corporate Reorganization'') of the Oi Companies. The Corporate Reorganization was effectively completed on February 27, 2012 and consisted of the following steps:

• a split-off and share exchange under Brazilian law in which (1) Telemar transferred the shares of Coari that Telemar owned to Coari, (2) Coari assumed a portion of the liabilities of Telemar, (3) the common and preferred shares of Telemar (other than the shares of holders who exercise their withdrawal rights with respect to such shares) would be exchanged for newly issued common and preferred shares of Coari upon the termination of the period for exercise of withdrawal rights, and (4) Coari retained the Telemar shares exchanged for Coari shares, and as a result, Telemar became a wholly-owned subsidiary of Coari;
• the merger of Coari into Brasil Telecom, resulting in Coari ceasing to exist and Telemar becoming a wholly-owned subsidiary of Brasil Telecom; and
• the merger of TNL into Brasil Telecom, resulting in TNL ceasing to exist.

In connection with the Corporate Reorganization, the following events took place:

• On February 24, 2012, TmarPart exchanged all of the class A preferred shares of Telemar that it owned for common shares of TNL held by Jereissati Telecom S.A. (''Jereissati Telecom''), Andrade Gutierrez S.A. (''Andrade Gutierrez''), the parent of AG Telecom, and Bratel Brasil, each a shareholder of TmarPart, in order to ensure that upon the completion of the Corporate Reorganization, TmarPart retained the voting control of Brasil Telecom in order to comply with the legal and regulatory obligations of TmarPart to ANATEL;
• Bratel exchanged preferred shares of Telemar for common shares of TNL (under the same terms and conditions of the TmarPart exchange described above) held by Jereissati Telecom, Andrade Gutierrez, AG and LF, which they received as a result of exchanging their preferred shares of TNL for preferred shares and common shares of Oi according to the exchange ratios; and
• Brasil Telecom issued and distributed redeemable shares of Brasil Telecom to holders of Brasil Telecom shares prior to the mergers of Coari and TNL into Brasil Telecom and redeemed those shares for cash immediately following their issuance. In addition, Brasil Telecom was renamed Oi S.A.

The Corporate Reorganization was undertaken to:

• simplify the corporate structure of the Oi Companies, which was extremely complex and included three publicly-held companies with seven different classes of publicly-traded shares, and simplify the corporate governance of the Oi Companies by consolidating the shareholder bases of the Oi Companies in one public company with two classes of shares that will be traded in Brazil and abroad;
• reduce operational, administrative and financial costs following the consolidation of the general management of the Oi Companies, the simplification of their capital structure, and the improvement of their ability to attract investments and access the capital markets;
• align the interests of the shareholders of the Oi Companies;
• enhance the liquidity of the shares of Oi S.A. (formerly Brasil Telecom); and
• eliminate the costs of separate listings of the shares of TNL, Telemar and Oi S.A., as well as those costs arising from separately complying with the public disclosure requirements applicable to TNL, Telemar and Brasil Telecom.

Following the Corporate Reorganization, we hold a 23.25% economic interest in Oi S.A., including a direct interest of 15.54%.

Corporate Structure

We set forth below a simplified corporate chart of Oi before and after the Corporate Reorganization:

The purpose of our strategic partnership with Oi is to develop a global telecommunications platform that will allow for cooperation in diverse areas, with a view to, among other things, sharing best practices, achieving economies of scale, implementing research and development initiatives, developing new technologies, expanding internationally, particularly in Latin America and Africa, diversifying the services provided to our customers, maximizing synergies and reducing costs, and seeking to offer constant high quality services to our corporate and individual customers, while creating and adding value for our shareholders.

In connection with this strategic partnership, it was contemplated that the Oi Companies would use part of the proceeds received from share capital increases to acquire up to 10% of the outstanding ordinary shares of Portugal Telecom. On April 28, 2011, TmarPart, TNL and Telemar announced that they had acquired 62,755,860 ordinary shares of Portugal Telecom, representing 7.0% of Portugal Telecom's outstanding ordinary shares. As of January 23, 2012, the Oi Companies beneficially owned 64,557,566 ordinary shares of Portugal Telecom, representing 7.2% of Portugal Telecom's outstanding ordinary shares.

Corporate Governance

In connection with the formation of our strategic partnership with Oi, we entered into various shareholders' agreements with Oi's current shareholders in order to regulate corporate governance practices within Oi, establish the rules, procedures and quorums for the approval of certain matters by Oi's board of directors, board of executive officers and within Oi's shareholder structure, rights of first offer or first refusal in the sale of Oi's shares by its shareholders, tag-along rights and other provisions, and these rights allow us to play an active role in Oi's corporate governance. For example, our shareholders' agreements contemplate, among other things, (1) a lock-up period of five years with respect to AG Telecom, LF Tel and TmarPart, a right of first refusal over a non-control sale of AG

Telecom and LF Tel and over any sale of TmarPart, and a right of first offer and tag-along rights in case of a control sale of AG Telecom and LF Tel and (2) the need for our approval on certain corporate governance matters, including: (i) amendments to bylaws, (ii) mergers and acquisitions and shareholders agreements, (iii) dissolution, (iv) capital increases or reductions, (v) issuances of debt securities above a specified ratio and (vi) the annual budget and investments.

In connection with the strategic partnership with Oi, on April 28, 2011, at TNL's annual general shareholders meeting, Zeinal Bava, the Chief Executive Officer of Portugal Telecom, and Shakhaf Wine, an executive board member of Portugal Telecom, both nominated by Portugal Telecom, were elected as members of the board of directors of TNL, as we had announced on April 6, 2011. In addition, Mr. Bava was appointed a member of the board of directors of TmarPart, and Mr. Wine was appointed an alternate member of the board of directors of TmarPart.

Now that the Corporate Reorganization of Oi has been completed, we expect that Zeinal Bava and Shakhaf Wine will also be appointed to the board of directors of Oi S.A. at the annual shareholders' meeting of Oi S.a. scheduled for April 30, 2012.

In addition, on April 6, 2011, Otavio Marques de Azevedo, then the Chairman of TmarPart, and ´ Pedro Jereissati, Chief Executive Officer of TmarPart, were appointed to our board of directors and their appointment was ratified at Portugal Telecom's general meeting of shareholders held on May 6, 2011.

Our shareholder agreements in connection with our strategic partnership with Oi are described in more detail below.

PASA Participa¸coes S.A. and EDSP75 Participa¸ ˜ coes S.A. Shareholders' Agreements ˜

We currently hold a 25.3% economic interest in Telemar on a consolidated basis. Part of the structure we used in order to obtain such an interest in Oi was to acquire an indirect 35% interest in AG Telecom and in LF Tel, through a direct investment in PASA Participa¸coes S.A. and EDSP75 ˜ Participa¸coes S.A., respectively. We have a 35% direct economic interest in PASA Participa¸ ˜ coes S.A., ˜ and the remaining 65% economic interest in the company is held by Andrade Gutierrez Telecomunica¸coes Ltda. Likewise, we have a 35% direct economic interest in EDSP75 ˜ Participa¸coes S.A., and the remaining 65% economic interest in the company is held by La Fonte ˜ Telecom S.A. AG Telecom is wholly owned by PASA Participa¸coes S.A., and LF Tel is wholly owned by ˜ EDSP75 Participa¸coes S.A. ˜

In connection with our investments in PASA Participa¸coes S.A. and EDSP75 Participa¸ ˜ coes S.A., on ˜ January 25, 2011, we entered into two shareholders' agreements, one with Andrade Gutierrez Telecomunica¸coes Ltda. (in relation to PASA Participa¸ ˜ coes S.A.) and another with La Fonte ˜ Telecom S.A. (in relation to EDSP75 Participa¸coes S.A.). The initial terms of these shareholders' ˜ agreements expire on April 25, 2048 but may be extended for successive periods of 10 years with the consent of each of the parties.

These shareholders' agreements serve the purpose of regulating corporate governance within PASA Participa¸coes S.A. and EDSP75 Participa¸ ˜ coes S.A. and streamlining decision-making process between ˜ us, Andrade Gutierrez Telecomunica¸coes Ltda. and La Fonte Telecom S.A. in connection with our ˜ investments in Oi. For instance, under these shareholders' agreements:

• pre-meetings are to be held between the shareholders to decide in advance the matters to be analyzed during pre-meetings to be held under the Global Shareholders' Agreement and the Control Group Shareholders' Agreement; and
• approval of certain matters are subject supermajority vote of the shareholders (e.g, approval of, and amendments to, the annual budget of PASA Participa¸coes S.A., EDSP75 Participa¸ ˜ coes S.A., ˜ AG and LF Tel are subject to an 83% majority; the entering by PASA Participa¸coes S.A., ˜ EDSP75 Participa¸coes S.A., AG or LF Tel of any loan agreements in excess of R\$50 million, or ˜ the entering of any agreement imposing a pecuniary obligation on PASA Participa¸coes S.A., ˜ EDSP75 Participa¸coes S.A., AG or LF Tel in excess of R\$50 million, or the granting of any ˜ guarantees by PASA Participa¸coes S.A., EDSP75 Participa¸ ˜ coes S.A., AG or LF Tel in excess of ˜ R\$50 million, are subject to a 90% majority; and any amendments to the Global Shareholders' Agreement or the issuance of preferred shares by PASA Participa¸coes S.A., EDSP75 ˜ Participa¸coes S.A., AG or LF Tel, the approval of any decision subject to supermajority vote ˜ under the Global Shareholders' Agreement (defined as a ''material decision'' under the PASA Participa¸coes S.A. and EDSP75 Participa¸ ˜ coes S.A. shareholders' agreements), among other ˜ matters, are subject to the unanimous vote of the shareholders).

In addition, as long as we hold at least 17% of the voting and total share capital of each of PASA Participa¸coes S.A. and EDSP75 Participa¸ ˜ coes S.A., we have the right to appoint one member to the ˜ board of executive officers of each of these companies. On the other hand, reduction in our interest in PASA Participa¸coes S.A. or EDSP75 Participa¸ ˜ coes S.A. may change some of our rights under these ˜ agreements and in connection with the Global Shareholders' Agreement. For example, should our interest in PASA Participa¸coes S.A. or EDSP75 Participa¸ ˜ coes S.A. be reduced to less than 20.5% of the ˜ voting share capital of either of these companies, approval of certain ''material decisions,'' as defined in the preceding paragraph, subject to a 75% majority vote under the Global Shareholders' Agreement (for instance, approval of changes to the bylaws of TmarPart) would no longer require our consent.

These shareholders' agreements also contemplate:

• rights of first offer to the shareholders with respect to the transfer of the shares issued by PASA Participa¸coes S.A. and EDSP75 Participa¸ ˜ coes S.A.; ˜
• tag-along rights for our benefit in case of the sale of PASA Participa¸coes S.A. and EDSP75 ˜ Participa¸coes S.A. shares by Andrade Gutierrez Telecomunica¸ ˜ coes Ltda. or La Fonte ˜ Telecom S.A., as the case may be;
• a general restriction on the sale of the shares issued by PASA Participa¸coes S.A. and EDSP75 ˜ Participa¸coes S.A. by Andrade Gutierrez Telecomunica¸ ˜ coes Ltda. or La Fonte Telecom S.A, as ˜ the case may be, to our competitors; and
• a general right to PREVI, PETROS, FUNCEF and BNDESPAR, while they remain shareholders of TmarPart, or to any third parties which may acquire the shares held by these companies in TmarPart, to substitute Andrade Gutierrez Telecomunica¸coes Ltda. or La Fonte ˜ Telecom S.A. in the exercise of their preemptive rights under the PASA Participa¸coes S.A. and ˜ EDSP75 Participa¸coes S.A. shareholders' agreements in case we decide to sell our shares in ˜ PASA Participa¸coes S.A. and/or EDSP75 Participa¸ ˜ coes S.A. ˜

BNDESPar, PREVI, PETROS and FUNCEF Shareholders' Agreement

On January 25, 2011, PREVI, PETROS, FUNCEF, BNDESPAR, Andrade Gutierrez Telecomunica¸coes Ltda. and La Fonte Telecom S.A. entered into a voting bloc shareholders' agreement. ˜ The purpose of this shareholders' agreement is to regulate the exercise of voting rights with respect to, and general governance in connection with, PASA Participa¸coes S.A. and/or EDSP75 Participa¸ ˜ coes S.A. ˜ in case of the sale of our interest in PASA Participa¸coes S.A. and/or EDSP75 Participa¸ ˜ coes S.A. and ˜ the acquisition of such interest by any of PREVI, PETROS, FUNCEF or BNDESPAR, in which circumstance the purchaser, or purchasers, of our interest in PASA Participa¸coes S.A. and/or EDSP75 ˜ Participa¸coes S.A. will be deemed to be a single bloc and will succeed us in all our rights and ˜ obligations. We are not party to this shareholders' agreement, and no obligation or right is imposed or conferred upon us.

Other International Operations

Concurrently with our investment in Oi, we acquired an interest in Contax, which provides contact center services, IT services and BPO services in Brazil and other Latin American countries. In addition, we have significant interests in telecommunications companies in Angola, Cape Verde, Namibia and Sao Tom ˜ e and Principe in Africa and in Macau and East Timor in Asia. We describe these investments ´ in more detail below.

Our subsidiary Portugal Telecom Investimentos Internacionais—Consultoria Internacional, S.A. manages all of our international businesses other than our investments in Oi and Contax.

Other Brazilian Operations

Brazilian Contact Center Operations

Concurrently with our investment in Oi, we acquired a 16.2% economic interest in CTX Participa¸coes S.A. (''CTX''), the parent company of Contax Participa¸ ˜ coes S.A. (''Contax Participa¸ ˜ coes'') ˜ and Contax S.A. (''Contax''). Even before our investment in Contax, we provided call center services in Brazil through our subsidiary Dedic, S.A. (''Dedic''), and Dedic's subsidiary GPTI—Tecnologias de Informa¸cao, S.A. (''GPTI'') provided IT/IS services in Brazil. On June 30, 2011, we merged Dedic ˜ and GPTI into Contax, and our economic interest in Contax increased to 19.5%. We have proportionally consolidated the results of operations of Contax in our results of operations since

April 1, 2011, and Contax's results of operations have included the results of operations of Dedic and GPTI since July 1, 2011. The impact of the proportional consolidation of Contax from April 1, 2011 (including Dedic and GPTI from July 1, 2011) was A358.8 million (R\$834.8 million).

Dedic and GPTI had consolidated revenues of R\$311.5 million (A133.9 million) from January 1, 2011 through June 30, 2011, the period before they merged with Contax. Dedic's revenues were R\$479.4 million in 2010 (A205.6 million) and R\$402.3 million in 2009 (A145.2 million), and GPTI's operating revenues were R\$133 million in 2010 (A56.9 million).

Strategic Partnership with Contax

AG and LF Tel, two of the significant shareholders of TmarPart, are also the controlling shareholders of Contax Participa¸coes. In connection with the Oi transaction, we agreed to merge Dedic ˜ and GPTI with Contax in return for common and preferred shares of Contax. In this transaction, we acquired a 16.2% interest of CTX, the parent company of Contax Participa¸coes and Contax, for ˜ consideration of R\$116 million. Following the exchange of our interest in Dedic and GPTI for an additional economic interest in Contax, we raised our interest in CTX to 19.9% through the contribution of a portion of the Contax preferred shares we had through this exchange. Also in connection with this transaction, we received net cash of approximately R\$162 million from the reimbursement by Contax of shareholder loans we had granted to Dedic prior to this transaction.

Following the merger of Dedic and GPTI with Contax, we hold a 19.5% economic interest in Contax through a 19.9% direct interest in CTX, which holds 34.2% of Contax, and a 4.3% direct economic interest in Contax. Our direct economic interest in Contax consists of 7.0% of Contax's outstanding common and preferred shares, which we are free to sell at any time.

In connection with this transaction, on January 25, 2011, we entered into a shareholders' agreement with the other CTX shareholders, that is, AG Telecom, Luxemburgo, LF Tel and FASS through our subsidiary Portugal Telecom Brasil S.A., effective as of March 28, 2011 (the ''Contax Shareholders' Agreement''). AG Telecom, Luxemburgo, LF Tel, FASS and Portugal Telecom Brasil S.A. are parties to the Contax Shareholders' Agreement, while CTX, Portugal Telecom, Andrade Gutierrez Telecomunica¸coes Ltda., PASA Participa¸ ˜ coes S.A., La Fonte Telecom S.A. and EDSP75 ˜ Participa¸coes S.A. are intervening parties in the Contax Shareholders' Agreement. ˜

Under the Contax Shareholders' Agreement, we have similar rights to those contained in the Global Shareholders' Agreement and the other shareholders' agreements described above under ''—Brazilian Operations (Oi)—Strategic Partnership with Oi,'' and, accordingly:

• pre-meetings are to be held among the shareholders to decide in advance the matters to be voted during any shareholders' or board of directors' meetings and the decisions taken during such pre-meetings shall be binding upon the shareholders and their representatives; and
• approval of certain matters are subject to a supermajority vote of the shareholders (for instance, approval of amendments to CTX's bylaws, of the execution of any agreements with Telemar and certain other matters are subject to a 66.67% majority; approval of CTX's annual budget and the investment plans of CTX and its subsidiaries, among other matters, are subject to a 70% majority; approval of the sale of the shares issued by CTX's subsidiaries and of any merger, spin-off, or initial public offering involving CTX, among other matters, are subject to an 84% majority).

In addition, (i) as long as we hold at least 10% of CTX's voting share capital, we have the right to appoint two members to the board of directors of both CTX and Contax Participa¸coes; (ii) as long as ˜ we hold at least 5% of CTX's voting share capital, we have the right to appoint one member to the board of directors of both CTX and Contax Participa¸coes; (iii) as long as we hold at least 11% of ˜ CTX's voting share capital, we have the right to appoint one member to the board of executive officers of CTX. Also, under the Contax Shareholders' Agreement, we have the right to veto one among three of the nominees appointed by AG Telecom, Luxemburgo, LF Tel and FASS to the position of chief executive officer of Contax.

The Contax Shareholders' Agreement also contemplates preemptive rights to the shareholders with respect to the transfer of CTX's shares and tag-along rights in case of the sale of CTX's shares by its shareholders. More importantly, however, (i) the corporate control in any of CTX's shareholders may not be transferred without such shareholder first offering its CTX's shares to the other CTX shareholders in accordance with the procedures contained in the Contax Shareholders' Agreement concerning the rights of first offer; and (ii) should we cease to be a TmarPart shareholder, our interest in CTX may be redeemed or exchanged in accordance with the procedures established in the Contax Shareholders' Agreement.

The Contax Shareholders' Agreement was executed on January 25, 2011, and its first term expires on April 25, 2048. The term of the Contax Shareholders' Agreement may be extended for successive periods of 10 years with the consent of each of the parties thereto.

Disposition of UOL Investment

On December 29, 2010, we reached an agreement for the sale of our 28.78% interest in Universo Online S.A., Brazil's largest internet provider by revenue, to a Brazilian businessman, for R\$356 million. UOL's total operating revenues were R\$816.7 million in 2010 (A350.5 million), R\$726.4 million in 2009 (A262.2 million) and R\$577.2 million in 2008 (A216.2 million).

Competition

We face substantial and increasing competition. The Portuguese telecommunications' sector has been fully open to competition since January 1, 2000. The competitive conditions of each of our business segments are described below.

Competition Facing Our Portuguese Operations

We face heavy competition from various telecommunications operators. Our primary competitors in Portugal include ZON (with financial institutions as the main shareholders, as well as Kento Holding Limited with a qualified participation of 10% and Telefonica with 5.0%), Sonaecom (which is 53.2% ´ owned by Sonae, SGPS, S.A. and 20% owned by France Telecom), Vodafone Portugal (a Vodafone Group subsidiary), Oni Telecom—InfoComunica¸coes, S.A. (60.9% owned by Riverside Europe ˜ Telecom LLC fund and 34.6% owned by Gestmin SGPS), Cabovisao (previously 100% owned by ˜ Cogeco Cable, the fourth Canadian cable operator, which sold it to Altice, a European private equity group, in early 2012), AR Telecom and Colt.

ZON began operations in November 2007, after the failure of Sonaecom's attempt to take over Portugal Telecom and our subsequent spin-off of PT Multimedia. ZON is the leader of the Pay-TV business in Portugal. Due to increasing competition in its core business, ZON has been aggressive in acquiring competitors and businesses, such as AR Telecom in November 2011, and expanding into other business segments, such as fixed voice and internet.

The competitive environment has been becoming more challenging for several reasons, such as the expansion of mobile operators that entered into the fixed market and, conversely, the entry of fixed operators into the mobile business. Operators that were previously more focused on one service have also diversified their operations through the launch of bundled offers with a strong focus on 3P (triple play) commercial configurations. This strategy has been followed by several players, namely Meo (our own brand), ZON, Cabovisao, Vodafone and Sonaecom. Among these players, both Portugal Telecom ˜ and ZON have a strong 3P customer base (Portugal Telecom with 602 thousand customers in 2011, an increase of 32.9% from 2010 and ZON with 709 thousand customers, an increase of 10.3% from 2010). Of our fixed-line customers, 36.9% have triple play services, and 60.1% of ZON's cable TV customers have triple play services, according to ZON's press release. We compete in terms of content and price through the launch of bundle offers combining several services.

Residential Customers

We face increasingly strong competition from fixed line operators as well as from mobile players, including our own mobile service provider, TMN. Currently, all mobile network operators have commercial offers that are a direct alternative to our fixed line telephone services, competing for the same customers. Residential services supported by mobile networks are offered by all mobile operators. In addition, these have also launched low-cost brands that are designed to reach the lower-end segment of the mobile market and have also had an effect on fixed line retail service.

More recently, operators have been offering unlimited voice communications to all national and up to 50 international fixed destinations, whenever the fixed voice service is purchased as part of a fixed service bundle. This competitive movement aimed to respond to the eroding revenues from international telephone service due to falling international call prices, extensive usage of lease lines by large users through which they connect to networks outside Portugal and aggressive competition from calling cards, rerouting of calls by other international operators and VoIP, which increasingly enables

communications at lower prices than traditional public switched telephone networks. These factors put significant pressure on us to reduce international fixed line telephone prices.

In the fixed voice market, Portugal currently has a penetration of 42.5 per 100 inhabitants (42.1% in 2010). According to ANACOM, we hold an estimated 58.7% market share of access lines (60.4% in 2010). The fixed voice market in Portugal is mainly a direct access market, which resulted from operators being more focused on direct access commercial offers and placing strong emphasis on customer migration from pre-selection configurations. Measures such as call-by-call selection (introduced in January 2000), carrier pre-selection (introduced in October 2000) and number portability (introduced in July 1, 2001) did not have a significant impact on that dynamic. According to ANACOM, as of December 31, 2011, there were approximately 122 thousand lines in pre-selection, the lowest figures since 2001.

Using the same source and our own estimates, we had an estimated 56.7% market share of total outgoing traffic in 2011, a decrease of 1.6% compared to 2010. This trend affected all categories of traffic, except for international traffic, where we had a 56.6% market share in 2011, an increase of 1.7% compared to 2010.

By the end of 2011, fixed broadband Internet surpassed 2 million customers in Portugal, with a market penetration at 21.1 per 100 inhabitants, up from 20 per 100 inhabitants in 2010, and still showing a significant upside potential. According to ANACOM, we are the top providers of these services, with 49.4% market share, an increase of 2.6% from 2010.

The Pay-TV market has a total of 2,976 thousand customers, according to ANACOM data, representing a 51.7% penetration on households. ZON is the current market leader with a 53.9% market share, representing a 4% decrease from 2010. Our brand, Meo, has been steadily gaining market share, reaching 35% in 2011, representing a 5.1% increase from 2010. Cabovisao has struggled ˜ to maintain its market share, with 8.6% in 2011, a 0.8% decrease from 2010, while the remaining players have not been able to rise above their residual positions.

The competitive dynamics in the Pay-TV market led operators to present it as a high-value, mass-market service offer from the start. More recently, Pay-TV service players began implementing price-skimming strategies by launching new low-end offers, thus catering to all segments of the market. ZON first launched a 15-channel Pay-TV offer in mid-2011, which was soon followed by Meo's own offer. Later in the year, in light of the pending migration to digital terrestrial television (DTT) and the switch-off of analog television signals in Portugal, ZON introduced a new pricing plan that includes only the four current free-to-air channels in Portugal.

To prevent higher value customers from downselling to lower-end offers, these are being offered extra high-quality content at no additional cost, such as interactive television, video on demand and multi-screen, multi-device television (''Meo go'' and ''ZON Online''). Meo has recently pioneered ''Meo Kanal,'' an application allowing customers to create their own custom-made private or public areas that they can view and share with other Pay-TV subscribers.

We have committed to an ambitious FTTH roll-out strategy in the past few years, reaching approximately one million homes by the end of 2011. ZON and Cabovisao have leveraged on their ˜ coaxial cable networks to upgrade to the DOCSIS 3.0 standard. Sonaecom and Vodafone have based their offers mainly on IPTV, relying on lines leased from PT and their own FTTH network, which is being rolled out. The two joined forces to share their fiber-based networks, which they expect to reach approximately 400 thousand homes, mainly in Greater Lisbon and Greater Oporto regions.

Following the completion of their network deployment plans, operators are now using on their next-generation networks to focus on customer retention and acquisition through internet speed upgrades. Currently, the main operators are offering speeds of up to 400Mbps.

Personal Customers

By the end of 2011, there were approximately 158 active mobile cards per 100 inhabitants in Portugal, making it one of the European countries with the highest adoption rate of mobile services. This performance derives from an extremely dynamic market, where operators are devoted to providing an extended product portfolio in order to address an extensive range of communication needs of its customers.

In the mobile market, TMN (our mobile operation) competes with Vodafone Portugal and Optimus, the two other mobile network operators licensed to provide mobile telephone services in Portugal. In 2007, CTT, the Portuguese postal company, launched ''Phone-ix,'' an MVNO (Mobile Virtual Network Operator) supported by TMN's network. In 2008, ZON launched an equivalent structure under the brand ''ZON Mobile,'' a mobile virtual operation hosted by Vodafone Portugal's network.

Due to their shareholder structures, Vodafone Portugal and Sonaecom (Optimus) have access to substantial resources, cost synergies (e.g., network and equipment costs) and best practices (e.g., product development processes) to compete aggressively against TMN in the Portuguese mobile telephone market. In addition, by strengthening their position in the mobile business, these assets enable them to compete more directly and aggressively in the fixed-line services.

According to figures from ANACOM, as of the end of 2011, TMN had a 43.9% market share in terms of active mobile in the Portuguese market. Market share leadership is and will continue to be TMN's priority, as the main mobile competitors, Vodafone Portugal and Optimus, will continue to market their services aggressively.

In 2008, the Portuguese mobile market experienced an important development, the launch of aggressive on-net differentiated pricing plans, known as ''tribal plans,'' led by Optimus (with ''Tag'') and followed by TMN (''Moche'') and Vodafone Portugal (''Extreme'' and ''Extravaganza''). In addition to the tribal plans, some post-paid, on-net oriented bundles of ''voice+internet'' were launched by the three major mobile operators, namely TMN (''tmn unlimited''), Optimus (''Smart'') and Vodafone (''Best''). The focus was on net-oriented flat rate plans and bundles of ''voice+internet,'' where operators explore the concept of unlimited on-net voice calls, leading to an increase of minutes of usage and an erosion of average revenue per minute.

In early 2011 TMN pioneered an expansion of its pricing plan portfolio with the launch of ''e—e nunca mais acaba'', a pre-paid flat-fee on-net pricing plan that expands the tribal plan concept to all TMN customers. TMN's move was followed by Vodafone (''Vita 0'') and Optimus (''Zero'').

With respect to mobile broadband service, according to ANACOM data, there were 1,134 thousand customers using dongles/modems by the end of 2011. This achievement is largely explained by the e-initiative programs launched by operators under the ''information society'' commitments they undertook in connection with the award of UMTS licenses.

Mobile revenues have been under pressure not only from the competitive dynamics but also due to the regulatory framework. Mobile termination rates declined approximately 68.2% (from 11 eurocents to 3.5 eurocents) between December 2007 and December 2011, and further reductions will occur in 2012, with rates reaching 1.27 euro cents in December 2012. Roaming revenues have also been a subject of regulation as caps for retail voice were introduced in 2007 and are expected to be extended to retail data during 2012.

Mobile operators have been undertaking aggressive marketing efforts, which often have a subscription fee that allows cheaper access to telecommunications during a certain period. Aggressive pricing structures and campaigns have also been contributing to stimulate usage at the expense of eroding retail revenues.

A large spectrum auction took place in Portugal in November 2011, with TMN, Vodafone and Optimus as the only bidders. TMN, Vodafone and Optimus secured spectrum in 800 MHz, 1.8 GHz and 2.6 GHz for A113 million each, with Vodafone taking up extra spectrum in the 900 MHz (A30 million) and 2.6 GHz TDD (A3 million). The new spectrum will be used to launch innovative 4G LTE networks, allowing for mobile speeds of up to 150 Mbps.

All mobile operators have launched 4G LTE commercial offers in early 2012, both in the form of smartphones and dongles, and they have been marketing them aggressively. Operators have also been focusing on extending LTE network coverage as quickly as possible, with TMN reaching 80% of the population by April 2012.

Enterprise Customers

We face significant competition from several operators in the enterprise services market, namely ZON, Vodafone Portugal, Sonaecom, Oni Telecom, AR Telecom and Colt. These companies compete with us in providing data communications, voice services and internet services to business customers. Customers tend to have large volumes of traffic and complex virtual private network services with data, voice and video integration.

Our competitors may use satellite-based networks, public network operators' infrastructure, leased lines and their own infrastructure to provide telecommunications services to customers. These are all alternatives to our leased lines offer. As a result of competition, we have reduced our prices for leased lines and are focusing on value-added solutions based on Internet Protocol Virtual Private Networks (''IP VPN'').

Our strong investment in our FTTH network, as well as our commitment to the investment in a top-European level Data Center, allow us to take advantage of the cloud services business opportunity. Cloud services are considered to be an attractive growth point in the telecommunications industry, and we intend to position ourselves ahead of the competition to provide such services, which will be an additional source of revenue as well as a retention and loyalty tool in our data and corporate customer category.

Other Services

We also face competition in our wholesale services. Fixed and mobile operators, other than TMN, are establishing direct international interconnections with mobile or wireline operators outside Portugal, enabling them to offer international telephone services without using our network. This is decreasing wholesale revenues generated from connecting mobile operators in Portugal to operators abroad.

The interconnection business faces more direct competition now that operators are focusing on installing and operating their own public wireline telephone networks, pushing for direct access offers.

Some international operators are now providing wholesale services in Portugal, including international telephone services, network interconnection, data services, and broadband access to Portuguese ISPs.

Competition Facing Oi in Brazil

Now that Telefonica has acquired Vivo from us, Vivo is the largest competitor of Oi, our Brazilian ´ telecommunications business. Vivo is controlled by Tel ´ efonica, a large Spanish telecommunications ´ company with significant resources. The other principal competitors of Oi are Claro, which is controlled by a consortium led by Telecom Americas Ltd. (''Telecom Americas'') (controlled by Am ´ erica ´ Movil, S.A.B. de C.V., a large Mexican telecommunications company (''Am ´ erica M ´ ovil'')), TIM, which is ´ controlled by Telecom Italia S.p.A. (''Telecom Italia''), a large Italian telecommunications company, and GVT, which is controlled by Vivendi S.A.

Oi faces intense competition in all the areas in which it operates from other mobile service and fixed-line operators. Many of these competitors are part of large, national or multinational groups and have access to financing, new technologies and other benefits that are derived from being a part of such a group. Fixed-line operators generally charge much lower tariffs than mobile service providers.

Residential Services

Local Fixed-Line Services

In the local fixed-line telecommunications services market in Brazil, competition has historically been focused on corporate customers. However, recently the competitors have begun compete in the consumer market with bundles or services targeted to the needs of lower income customers. In addition, competition from other telecommunication services has been increasing, particularly from mobile telecommunication services, which has led to traffic migration from fixed-line traffic to mobile traffic and the substitution of mobile services in place of fixed-line services, encouraged by offers of aggressively priced packages from some mobile telecommunication service providers. Finally, the decrease in interconnection rates has discouraged the construction of new fixed-line networks and has led to decreases in market prices for telecommunication services by enabling telecommunication service providers that use the local fixed-line networks of incumbent fixed-line providers to offer lower prices to their customers.

Oi is the leading provider of local fixed-line services in Region I of Brazil with 12.0 million fixed lines in service and an estimated market share of 72.7% of the total fixed lines in service in this region as of December 31, 2011, based on information available from ANATEL. Oi's principal competitors in Region I for fixed-line services are (1) Embratel (an affiliate of Telecom Americas), which had an estimated market share of 17.4% of the total fixed lines in service in this region as of December 31, 2011, and (2) GVT (an affiliate of Vivendi S.A.), which had an estimated market share of 5.0% of the total fixed lines in service in this region as of December 31, 2011, in each case, based on information available from ANATEL. During 2011, GVT increased its competitive activities in Region I, expanding its fiber optic network in high-income residential areas and increasing its services to low- and medium-size businesses.

Oi is the leading provider of local fixed-line services in Region II with 6.8 million fixed lines in service and an estimated market share of 66.4% of the total fixed lines in service in this region as of December 31, 2011, based on information available from ANATEL. Oi's principal competitors in Region II for fixed-line services are (1) GVT, which had an estimated market share of 18.5% of the total fixed lines in service in this region as of December 31, 2011, and (2) Embratel, which has an estimated market share of 11.0% of the total fixed lines in service in this region as of December 31, 2011, in each case, based on information available from ANATEL.

Embratel provides local fixed-line services to residential customers through the cable network owned by its subsidiary NET in the portions of Regions I and II where NET provides cable television service. As a result, NET is able to offer cable television, broadband and telephone services as a bundle at a very competitive price. NET has engaged in efforts to promote Embratel's fixed-line service by offering free local fixed-line service to its customers for a period of one year. Oi expects competition from Embratel to increase as the cable network of NET expands through internal growth and as a result of acquisitions.

Oi also expects competition from Embratel and GVT to increase in certain large cities, such as Rio de Janeiro, Belo Horizonte and Salvador, where they continue to expand their respective local fixed-line network. GVT has also begun to expand in some medium-sized cities with population in the range of 350,000 to 1,000,000.

TIM and Vivo have entered the local fixed-line services market by offering fixed-line wireless services, which, unlike traditional mobile services, only permit a subscriber to place and receive calls when in proximity to a single specified radio base station. These services allow TIM and Vivo to offer fixed-line service without installing a network of fixed lines directly to the homes or businesses of their fixed-line customers. As of December 31, 2011, TIM has a market share of 1.2% in the Brazilian local fixed-line services market.

Oi expects to continue to face competition from mobile services providers, which represent the main source of competition in the local fixed-line service market. As of December 31, 2011, there were 122 million mobile subscribers (including Oi's mobile customers) in Region I, a 18.0% increase over December 31, 2010, there were 61 million mobile subscribers (including Oi's mobile customers) in Region II, a 14.0% increase over December 31, 2010, and there were 60 million mobile subscribers (including Oi's mobile customers) in Region III, a 16.0% increase over December 31, 2010, based on information available from ANATEL. The increase in the number of mobile users, in addition to reduced mobile services rates, is expected to continue to adversely affect the number of fixed-line subscribers and the volume of local fixed-line traffic. In addition, because mobile providers offer promotions and service plans that permit subscribers to make calls within the mobile provider's network at rates that are less than those charged for calls from a fixed-line telephone to a mobile telephone, Oi believes that it may be vulnerable to traffic migration as customers with both fixed-line and mobile telephones use their mobile devices to make calls to other mobile subscribers.

We believe that major technological innovations, such as instant messaging services and VoIP, may impact local fixed-line traffic in the future. In Brazil, those services have been increasing in popularity, which could put further pressure on the local fixed-line telecommunications market.

Long-Distance Services

The long-distance services market in Brazil is highly competitive. For the year ended December 31, 2011, based on information available from ANATEL, of the total number of long-distance minutes originated in Region I, Oi had a market share of 9.1%, ranking behind TIM with 57.4% and Embratel with 29.8%, of the total number of long-distance minutes originated in Region II, Oi had a market share of 17.4%, ranking behind TIM with 48.0% and Embratel with 26.1%, and of the total number of long-distance minutes originated in Region III, Oi had a market share of 10.1%, ranking behind TIM with 34.5%, Embratel with 29.0% and Telesp (a subsidiary of Telefonica) with 20.3%. ´

Oi's principal competitor for long-distance services is TIM, which in 2010 began aggressively promoting its long-distance services with significant discounts. Historically, Oi's principal competitor for long-distance services has been Embratel. As a result of Oi's commencement of mobile services in Region III, Oi has also begun to compete with Telesp, which is the incumbent fixed-line service provider in Region III.

Generally, callers placing fixed-line long-distance calls in Brazil tend to select the long-distance carrier affiliated with the provider of their fixed-line service. Similarly, callers placing mobile long-distance calls in Brazil tend to select the long-distance carrier affiliated with the provider of their mobile or fixed-line service. However, increased competition from long-distance service providers has resulted in pressure on the long-distance rates and adversely affected Oi's revenue from these services.

In addition, the offering of plans by other mobile services providers that include free minutes for calls to other subscribers of those mobile services providers may adversely impact Oi's revenues from mobile long-distance calls if Oi's mobile customers migrate to its competitors to remain within the network of the people to whom they plan to place long-distance calls. However, as a result of the increased use of SIM card-only strategies by other mobile service providers, there is a trend among Brazilian pre-paid customers to purchase SIM cards from multiple mobile service providers to maximize the number of calls that they can make which are covered by these promotional offers.

New technologies that serve as an alternative to traditional long-distance telephone calls, such as VoIP, may start to capture part of Brazil's long-distance traffic. However, in contrast to what has occurred in other countries, such as the United States, Oi does not expect intense competition from VoIP providers in the near term due to the low level of broadband penetration in Brazil due to the population's relatively low per capita income and the expected adverse effect of the success of this technology on the long-distance call margins of Embratel, which is an affiliate of NET, the main service provider with the ability to offer alternatives through VoIP.

Data Transmission Services

Cable television providers that offer broadband services, particularly NET, represent Oi's principal competition in the broadband market in Brazil. Oi faces competition from these providers that offer integrated packages, consisting of subscription television, broadband and voice telephone services to cable television subscribers who, in general, have more purchasing power than other consumers.

Oi's principal competitors in the commercial data transmission services market are Embratel, GVT and Intelig. Because the commercial data transmission services market is significantly less regulated than the fixed-line, long-distance and mobile services markets and, therefore, presents fewer barriers to entry, this market is subject to competition from a large number of competitors, including fixed-line telecommunication service providers and specialized services companies competing in this high-growth market and focused on large- and medium-sized business customers. Along with growth in traffic volume and increasing demand for broadband capacity, Oi expects significant price reductions in data transmission services as competitors expand their networks. Oi also anticipates a shift in competition towards value-added services provided over IP platforms.

DTH Services

In Brazil, the high quality programming of television broadcasters has resulted in aggregate ratings for these broadcasters of approximately 90% of viewers and has limited the perceived value of subscription television. As a result, the subscription television market in Brazil has a low penetration compared to developed countries and even to other Latin American countries such as Argentina, Chile and Mexico. Penetration rates for subscription television have grown from 8.0% of Brazilian households in 2005 to 21.2% in 2011. According to information available from ANATEL, the Brazilian subscription television market grew by more than 30.7% in 2011.

The primary providers of subscription television services in Regions I and II in Brazil are Embratel, which provides DTH service under the ''Claro TV'' brand, SKY, which provides DTH services, and NET, which provides subscription television services using coaxial cable. Oi commenced offering DTH subscription television services to the low-income residential market in the states of Rio de Janeiro, Minas Gerais, Rio Grande do Sul, Parana and Santa Catarina. In 2010, Oi expanded this ´ service to the Federal District and the states of Bahia, Sergipe, Pernambuco, Ceara, Para ´ ´ıba, Rio Grande do Norte, Alagoas, Esp´ırito Santo and Goias. In 2011, Oi expanded this service to the ´ remaining states of Regions I and II.

Personal Services

The mobile telecommunications services market in Brazil is characterized by intense competition among providers of mobile telecommunications services. Oi competes primarily with the following mobile services providers, each of which provides services throughout Brazil:

• Vivo, which is controlled by Telefonica and which markets its services under the brand name ´ ''Vivo'';
• TIM, which is a subsidiary of Telecom Italia and markets its services under the brand name ''TIM''; and
• Telecom Americas Group, which markets its services under the brand name ''Claro.''

In December 2010, Nextel Brazil acquired licenses to provide 3G services throughout Brazil. Nextel has announced that it expects to launch commercial services on its 3G network in certain markets between June and December 2012. Oi expects that Nextel's entrance in the market will increase competition for mobile services.

As of December 31, 2011, based on information available from ANATEL, Oi had a market share of 23.2% of the total number of subscribers in Region I, ranking behind Vivo with 27.2% and TIM with 26.7%, and ahead of Claro with 22.5%, and Oi captured 19.9% of all net additions of mobile subscribers in Region I (calculated based on the number of mobile subscribers at the end of a period less the number of mobile subscribers at the beginning of that period) during 2011.

As of December 31, 2011, based on information available from ANATEL, Oi had a market share of 14.2% of the total number of subscribers in Region II, ranking behind Vivo with 30.8%, Claro with 28.6% and TIM with 26.3%, and Oi captured 9.0% of all net additions of mobile subscribers in Region II during 2011.

As of December 31, 2011, Oi had a market share of 14.5% of the total number of subscribers in Region III, ranking behind Vivo with 33.0%, Claro with 26.1% and TIM with 26.3%. Based on information available from ANATEL, Oi captured 16.4% of all net additions of mobile subscribers in Region III during 2011.

Competitive efforts in the Brazilian mobile telecommunication services market generally take the form of handset subsidies in the post-paid market and traffic subsidies in both the pre-paid and post-paid market. The aggressiveness of promotions is generally driven by the desire of the provider offering the promotion to increase market share; however, these promotions generally are for a short duration as the pricing terms offered are not sustainable over the long term.

Regulation

Portugal

In the competitive Portuguese telecommunications market, the regulatory measures which most affect our operations, our revenues and our costs relate to:

• restrictions on the products we offer and the prices we charge for residential fixed line voice services;
• restrictions on our broadband retail products through the application of retail-minus rules in those areas considered non-competitive;
• obligations to allow our competitors to interconnect with and use our fixed line network;
• certain fixed line services that we are obliged to provide to the public under our ''universal service obligation'';
• measures that are intended to make it easier for our customers to migrate to our competitors' services, including carrier pre-selection, number portability, unbundling of the local loop, and wholesale line rental;
• the terms of our concession and our licenses; and
• price controls on our wholesale reference offers, such as local loop unbundling, wholesale line rental, interconnection offers, ADSL bitstream offers (in those areas considered non-competitive), access to ducts, leased lines trunks and local segments.

EU Regulatory Framework and Relevant Markets

In February 2002, the European Union agreed upon a new regulatory framework for electronic communications networks and services, consisting of five directives governing procedures, authorizations, access, universal service and data protection; one decision on the availability and use of radio spectrum; and a recommendation on relevant product and service markets within the electronic communications sector subject to ''ex ante'' regulation in accordance with Directive 2002/21/EC of the European Parliament and Council on a common regulatory framework for electronic communications networks and services. Four of the five directives that make up the new EU framework were adopted into law in Portugal on February 10, 2004 as part of Law 5/2004, the Basic Law of Electronic Communications (''Law 5/2004''). The fifth directive was adopted into law on August 18, 2004.

In 2006, the European Commission began a review of the new EU framework, for electronic communications services and networks. The new regulatory package was approved on November 25, 2009 and published in the Official Journal of the European Union of December 18, 2009 (OJ—L 377, 18.12.2009). The new EU Framework was transposed into national law by Law No. 51/2011 of September 13, 2011.

The implementation of the new EU framework is changing the current regulatory framework applicable to us. The new EU directives and recommendations, which adopt competition law principles such as market dominance for the designation of significant market power and the definitions of relevant product and geographic markets which may be subject to ''ex ante'' regulation, constitute in significant changes and refinements to the regulatory framework. The new framework focuses on issues such as reinforcing consumer rights, encouraging competitive conditions among operators to increase consumer choice, promoting investment in new communications infrastructure (such as by freeing spectrum for the provision of broadband services) and ensuring network security and integrity.

Under the new regulatory regime, regulatory obligations can be imposed on operators having significant market power in any one of the relevant retail and wholesale markets identified by the European Commission. On December 17, 2007, the European Commission issued its European Relevant Markets Recommendation, which defines one retail market and six wholesale markets. Since we are active in all of these markets, any new regulatory measures could affect our businesses and operations.

Prior to the release of the new European Relevant Markets Recommendation, ANACOM had analyzed 16 of 18 retail and wholesale markets (as defined under a prior European Commission Recommendation). ANACOM found Portugal Telecom to have significant market power in all the markets it has analyzed except for one in which it did not find any operator to have significant market power (wholesale transit services). These markets include the following: (1) retail markets—access to the public telephone network at a fixed location (residential and business), publicly available local and/or national telephone services provided at a fixed location (residential and business), publicly available international telephone services provided at a fixed location (residential and business), and leased lines; and (2) wholesale markets—call origination on the fixed telephone network provided at a fixed location, call termination on individual public telephone networks provided at a fixed location and wholesale unbundled access to local metallic loops, wholesale leased lines (trunk segments and terminating segments) and wholesale broadband access. In addition, ANACOM added a nineteenth market, covering telephone services at a fixed location using non-geographic numbers, such as toll-free numbers, and has declared the Portugal Telecom group to have significant market power in this area. Now, under the new European Commission Recommendation on Relevant Markets, ANACOM will be required to re-analyze the retail and wholesale markets and identify which electronic communications operators and service providers it considers to have significant market power in such markets in Portugal and notify the European Commission with respect to its findings. ANACOM has conducted a market analysis to determine the regulatory obligations that should be imposed on operators with

significant market power in the provision of wholesale (physical) network infrastructure access and wholesale broadband access.

Wholesale Markets 4 and 5 (for the provision of wholesale (physical) network infrastructure access and wholesale broadband access) were analyzed by ANACOM in 2008 and early 2009. ANACOM decided to segment the broadband market geographically between ''C'' (competitive) areas and ''NC'' (non competitive) areas. ANACOM also removed the regulation that was imposed on Portugal Telecom regarding wholesale broadband access in ''C'' areas, namely the retail-minus rule. Additionally, Portugal Telecom's obligation to provide a bitstream reference offer (Rede ADSL PT) expired after a transitional period of one year from the date of the final decision in January 2009. However, we have decided to maintain the bitstream reference offer (Rede ADSL PT). In February 2012, ANACOM issued a consultation on the review of relevant Markets 4 and 5 to integrate the changes due to the development of Next Generation Networks. ANACOM is proposing to introduce virtual access to fiber (an advanced bitstream offer) as a remedy in Market 4 but with geographic differences: virtual access to fiber is not to be imposed in 17 municipalities where fiber networks have already been, or are likely to be, replicated by alternative operators. See ''—Next Generation Access Networks'' below.

In addition to Portugal Telecom, all other fixed line operators in Portugal were determined to have significant market power in the call termination on individual public telephone networks provided at a fixed location wholesale market. Likewise, all mobile network operators were found to have significant market power in the call termination on individual mobile networks. In 2010, ANACOM conducted a market analysis of the wholesale leased lines terminal and transit segments, on minimum sets of retail leased lines and on mobile termination rates. ANACOM eliminated the minimum set of retail leased lines and the retail-minus rules with respect to this set of leased lines. ANACOM found Portugal Telecom to have significant market power in the wholesale leased lines terminal market and segmented the transit segments between ''C'' (competitive) routes and ''NC'' (non competitive) routes. In these wholesale markets, ANACOM included Ethernet connections and imposed the retail-minus rule over Ethernet solutions. In the ''C'' routes, Portugal Telecom has no significant market power. We expect that in the near future, ANACOM will provide further analysis of the other relevant markets.

Regulatory Institutions

ANACOM. The Autoridade Nacional das Comunica¸coes ˜ (''ANACOM'') created in January 2001 (formerly Instituto das Comunica¸coes de Portugal ˜ ) (''ICP''), is the Portuguese telecommunications regulator. It advises the Portuguese government on telecommunications policy and legislation and monitors compliance with concessions, licenses and permits granted to telecommunications providers in Portugal.

ANACOM is accountable to the Ministry of Public Works, Transport and Communications. The Ministry of Public Works, Transport and Communications retains basic responsibility for telecommunications policy in Portugal. Together with the Ministry of Finance, it has ultimate responsibility for monitoring our compliance with our concession. It also has certain supervisory powers with respect to our activities. The Portuguese government delegated a significant number of those powers and functions to ANACOM in our concession agreement.

Over the past several years, the Portuguese government has substantially increased the autonomy of ANACOM and has allowed it to become a more effective and independent regulatory body. ANACOM acts on complaints against us by our competitors, our customers and other interested parties. It can impose fines on us if we do not meet our obligations under our concession, including our obligations to supply public switched wireline telephone services, leased lines and other services to our competitors on a timely basis. ANACOM has, from time to time, addressed complaints against us by our competitors. However, such complaints have been resolved in a manner that has not had a material

adverse effect on our businesses or operations. ANACOM's decisions are subject to possible reconsideration and can be submitted for judicial review.

European Commission. Most of the EU competition rules have the force of law in all EU member states and therefore apply to us in Portugal. The current priority of the European Commission is to ensure that EU member states fully and correctly implement EU requirements in national law. The European Commission routinely monitors the status of EU member states in implementing EU directives.

The Directorate-General for Competition of the European Commission is responsible for considering, on its own initiative as well as in response to complaints by interested parties, potential claims that our business activities or Portuguese government regulations are inconsistent with the key provisions of the Treaty of Lisbon, also known as the TFEU Treaty, relating to competition in the EU. Article 101 of the treaty prohibits agreements or coordinated action between competitors that may affect trade between EU member states and have as their objective or effect the prevention, restriction or distortion of competition within the EU. Article 102 of the treaty prohibits any abuse of a marketdominating position within the EU, or a substantial part of the EU, that may affect trade between EU member states. The Directorate-General for Competition enforces these rules in cooperation with the national competition authorities. In addition, national courts have jurisdiction over violations of EU competition law.

Autoridade da Concorrˆencia. Our activities are also overseen by the Autoridade da Concorrencia ˆ (formerly ''Direc¸cao Geral do Com ˜ ´ercio e da Concorrˆencia'') (''DGCC''), which is responsible for enforcement of Portuguese competition law. It is also responsible for considering complaints relating to our business practices or other business arrangements. We and our subsidiaries are permitted under Portuguese law to appeal any adverse decision of the Autoridade da Concorrencia to the courts. Such ˆ an appeal suspends the decision of the Autoridade da Concorrencia pending a decision by the courts. ˆ

ERC. The Entidade Reguladora para a Comunica¸cao Social ˜ (''ERC'') is the independent regulatory authority for the Portuguese media. ERC's primary responsibilities are the regulation and supervision of all entities that undertake media activities in Portugal. ERC is a legal entity endowed with administrative and financial autonomy.

ERC oversees compliance with respect to fundamental rights such as freedom of the press, right to information, independence from political and economic power and freedom of speech. It is also responsible for monitoring compliance by all companies operating in the media sector, with standards for media and broadcast content, as well as for promoting the proper and effective functioning of the market where such companies operate.

ERC's decisions may affect, among others, news agencies, periodicals, radio or television operators, and radio and television broadcasters. PT Comunica¸coes and TMN are usually considered television ˜ broadcasters, and as such we must pay ERC supervisory and regulatory fees, which are calculated based on the amount of work ERC does related to PT Comunica¸coes and TMN, the technical complexity of ˜ matters, the geographic range of networks used by the broadcasters, and the impact of the activity developed by each broadcaster.

Regulatory Proceedings

We are regularly involved in regulatory inquiries and investigations involving our operations. In addition, ANACOM, the European Commission, the Autoridade da Concorrencia and the ERC ˆ regularly make inquiries and conduct investigations concerning our compliance with applicable laws and regulations. Current inquires and investigations include several investigations by the Autoridade da Concorrencia relating to alleged anti-competitive practices in the broadband internet, public wireline ˆ

telephone, terrestrial television and public mobile telephone markets, as well as an investigation of the European Commission into alleged cooperation with Telefonica. ´

These investigations are described in more detail in ''Item 8—Financial Information—Legal Proceedings.''

Pricing of Fixed Line Telephone Services

ANACOM has established a pricing regime for fixed line telephone services in accordance with the terms of the new EU regulatory framework. This pricing regime creates the following regulatory obligations for the retail market for telephone services at a fixed location:

• The price cap applying a basket composed of residential access and domestic calls is the Portuguese Consumer Price Index (''CPI'') minus 2.75%.
• The fixed component of fixed-to-mobile calls (residential and non-residential) are required to be cost-oriented, and price controls are in place in the form of a cap of A0.063 on the amount retained by the fixed operator with respect to fixed-mobile calls.
• The tariffs for domestic payphone calls are required to correspond to a maximum of three times the tariff for a residential phone call.
• Also, since January 2007, we have been required to grant a 50% discount on our monthly fee for retired people, a price accessibility obligation that was included under our universal service obligations.

In addition, general regulatory obligations of transparency, non-discrimination, cost orientation, cost accounting and account separation apply to access to the fixed line network and to the telephone services at a fixed location.

Prices for Leased Lines

In July 2010, following ANACOM's final decision on the leased line markets, the retail leased line market was deregulated, which meant that our prices in this market ceased to be subject to a 26% retail-minus rule. However, for the wholesale leased line markets, in which we were declared as the operator with significant market power, ANACOM decided to make Ethernet circuits subject to a retail-minus rule that is still to be defined by ANACOM.

On November 17, 2011, ANACOM approved its earlier proposal on a leased lines reference offer (oferta de referˆencia de circuitos alugados, or ''ORCA'') and an Ethernet Accesses Reference Offer (oferta de referˆencia de circuitos Ethernet, or ''ORCE''). Under this decision, ANACOM seeks, among other things, to cause our subsidiary PT Comunica¸coes to decrease the price of all components ˜ included in its pricing list (including CAM lines) for 2 Mbps, 34 Mbps and 155 Mbps lines by 35%, 40% and 45%, respectively. A public consultation period ended in December 2011, and a decision is pending.

Universal Service Obligations

Law 5/2004 and our concession impose universal service obligations on us in Portugal. These obligations include providing connections to the public telephone network at a fixed location. They also include providing access to public switched fixed line telephone services, including enabling users to make and receive local, national and international telephone calls, facsimile communications and data communications. They also include providing public pay telephones, publishing directories and making available at least one telephone directory enquiry service covering all public voice telephone subscribers' numbers.

According to Law 5/2004, if ANACOM determines that the provision of universal service obligations has become an excessive burden, it may compensate us accordingly. Since 2004, it has been the responsibility of ANACOM to calculate the costs of providing the universal service.

In 2008, ANACOM issued a decision in which it refused to accept our calculations related to the costs of universal service for 2001, 2002 and 2003. ANACOM proposed to define a methodology to calculate the net costs of universal service (''NCUS'') and to provide definitional clarity on the concept of ''excessive burden.'' During 2009, with assistance from its consultants, PT Comunica¸coes ˜ developed a methodology to calculate the NCUS for 2008, and several meetings occurred between PT Comunica¸coes and ANACOM regarding the results obtained and the methodological choices that ˜ were made. ANACOM was expected to launch a consultation on these issues during the first half of 2010, but both consultations (on excessive burden and on the methodology to calculate the NCUS) were launched in February 2011 and continued until March 2011. In the consultations, ANACOM proposed to acknowledge the existence of an excessive burden in the universal service provision from 2007 forward and to calculate the NCUS using historical cost accounting data. In June 2011, ANACOM approved the decisions on the definition of excessive burden and on the methodology for the calculation of the NCUS. PT Comunica¸coes submitted a request to ANACOM defending the need ˜ to correct the methodology, and a final decision on this matter was adopted in August consistent with the request of PT Comunica¸coes. In December 2011, PT Comunica¸ ˜ coes submitted to ANACOM the ˜ calculation of the NCUS for the period between 2007 and 2010. We did not receive any final comment, but in accordance with the applicable law ANACOM will submit the calculation to an independent auditor.

From November through December 2011, ANACOM held a public consultation on the process for selecting a universal service provider. ANACOM issued a final decision in February 2012, dividing universal services by three functions (telephone service, pay telephones, and directory and inquiry services) and further in three geographic regions. On April 12, 2012, the government launched a public consultation on proposed legislation to establish a compensation fund for universal service providers, after which the Portuguese government is expected shortly thereafter in 2012 to launch a tender for the designation of the universal service providers. The designation of the universal service providers and related renegotiation of our concession are explicit objectives set forth in the memorandum of understanding entered into by the Portuguese government, the IMF, the European Commission and the European Central Bank in the context of the support package provided to Portugal.

Interconnection

The Interconnection Framework. The EU Access and Interconnection Directive requires that interconnection services be made available in a non-discriminatory manner. The EU Access and Interconnection Directive encourages commercial negotiations among operators but requires national regulatory authorities to establish mechanisms for effective dispute resolution. According to the EU Access and Interconnection Directive, all telecommunications companies with significant market power in the call origination or termination markets must:

• make interconnection access to their networks available to other network operators;
• not discriminate between interconnection customers;
• provide to those requesting interconnection the information and technical specifications necessary for them to interconnect their networks;
• offer interconnection prices that are transparent and cost-oriented and do not discriminate between interconnection customers; and
• maintain a separate accounting system for interconnection activities.

Law 5/2004 implemented the EU Access and Interconnection Directive in Portugal and established the general conditions for access and interconnection among telecommunications operators in competitive markets. It guarantees the rights of new entrants to obtain interconnection from telecommunications operators with significant market power.

Pursuant to Law 5/2004, ANACOM is entitled to review and modify our proposed interconnection rates and arrangements in our reference interconnection offer. ANACOM has established in Portugal an overall interconnection framework based on cost and consistent with the EU legal framework for both wireline and mobile services.

Wireline Interconnection. As a result of the enactment of Law 5/2004, ANACOM adopted a measure in 2004 on call origination on fixed telephone networks provided at a fixed location, call termination on individual public telephone networks provided at a fixed location and on significant market power designation in these fixed locations, declaring the Portugal Telecom group to have significant market power in these markets. As a result, we are subject to price controls in these markets based on our costs and other factors and must publish a reference offer that includes these prices and quality of service standards.

Mobile Interconnection. In 2005, all mobile operators were declared to have significant market power in call termination in mobile networks market. ANACOM has imposed price controls on interconnection rates for the termination of calls on mobile networks. These reductions have had, and are expected to continue to have, a significant impact on TMN's interconnection revenues and consequently its earnings.

In May 2010, ANACOM imposed a new glide path that reduced mobile termination rates by A0.005 per quarter, reaching A0.035 in August 2011. In April 2011, based on an EC Recommendation on fixed and mobile termination rates of May 2009, which required national regulatory authorities to develop bottom-up pure long-run incremental cost (''LRIC'') models to regulate mobile termination rates, ANACOM held a consultation on the definition of such a cost model to regulate mobile termination rates. In October 2011, ANACOM issued a new draft decision based on that cost model and proposed a new glide path, according to which mobile termination rates would decrease in four steps, reaching A0.0125 per minute in November 2012. In March 2012, ANACOM issued a final decision reducing mobile termination rates progressively to A0.0127 by December 2012. The reductions in mobile termination rates have had and will continue to have a negative effect on our cash flows and revenues.

Internet Access. As a result of past ANACOM decisions, we offer two access regimes to ISPs: (1) the Reference Offer for Internet Access, which includes two alternative pricing methods, namely a monthly flat rate and a per minute origination charge, and under which the connection of the ISP's infrastructure to our fixed line network is based on DSS1 signaling, and (2) the Reference Interconnection Offer, which includes a pricing method based on call origination, and under which the connection of the ISP's infrastructure to our fixed line network is based on Signaling System No. 7 (SS7) protocols. The ISPs determine which regime will apply to their arrangements to connect with our fixed line network.

Pricing for Mobile Origination Rates

In addition, in August 2008, ANACOM published a ''reasoning'' regarding mobile rates for originating calls, aimed at driving mobile operators to reducing their prices by the end of September 2008 to a level equal or close to the level of mobile termination rates. In the second half of 2008, the three mobile operators reduced their rates for originating calls but not to the extent desired by ANACOM. In February 2010, ANACOM chose to take the matter to the Portuguese national competition authority (the Autoridade da Concorrˆencia, or ''AdC''). In January 2012, the Autoridade da Concorrencia completed its analysis, finding origination rates to be excessive and stating that mobile ˆ operators must reduce their rates to the level of their costs by July 2012 or face the possibility of being sanctioned.

Next Generation Access Networks

In 2008, the European Commission launched a consultation on a draft recommendation on the regulated access to NGAs, seeking to define general regulatory principles and determine regulatory solutions for fiber-to-the-home (''FTTH'') and fiber-to-the-node (''FTTN''), including access to ducts, the unbundling of fiber and bitstream solutions. In 2009, the European Commission launched a second consultation on a draft recommendation on the regulated access to NGAs. In 2010, The European Commission approved the recommendation on the regulated access to NGAs, maintaining the primary regulatory principles. On January 19, 2011, the European Commission determined that state aid for implementation of next generation access networks was compatible with the EU Treaty.

In 2008, ICP-ANACOM launched a public consultation on the regulation of Next Generation Access Networks (''NGA''), which addressed several issues, namely market and technological issues, the impact of NGAs on existing networks, the development models, public policy considerations and regulatory models. In a decision announced in 2009, ANACOM defined a segmented approach: in areas designated ''C'' (competitive) areas, the main obligation is access to ducts, and in areas designated ''NC'' (non-competitive) areas, the obligations are access to ducts, access to fiber and advanced bitstream, subject to conditions. In February 2012, ANACOM issued a consultation on the review of relevant Markets 4 and 5 to integrate the changes due to the development of Next Generation Networks. ANACOM is proposing to introduce virtual access to fiber (an advanced bitstream offer) as a remedy in Market 4 but with geographic differences: virtual access to fiber is not to be imposed in 17 municipalities where fiber networks have already been, or are likely to be, replicated by alternative operators.

With respect to the roll-out of optic fiber networks, Decree-Law No. 123/2009 of May 2009, as amended by Decree-Law No. 258/2009, of September 2009, establishes a legal framework for the construction of and access to infrastructure suitable for the accommodation of electronic communications networks and the construction of infrastructure for telecommunications in housing developments, urban settlements and concentrations of buildings. As for rights of way—especially access to the public domain, expropriation and the constitution of public easements—the law reinforces the rights already given to electronic communications undertakings under Law No. 5/2004 by introducing a new level of harmonization and transparency in procedures. In particular, Decree-Law No. 123/2009 sets forth several obligations in order to allow electronic communications operators to enjoy better conditions necessary for the installation and development of electronic communications networks.

Decree-Law No. 123/2009 also foresees the implementation of a Centralized Information System (''SIC'') to be managed and operated by ANACOM and whose main objective is to make available information on infrastructure appropriate for the installation of electronic communications networks based on information provided by the Portuguese government, autonomous regions, municipalities, publicly held companies or concessionaires, other entities owning or using infrastructure in the public domain, autonomous regions or municipalities and electronic communications undertakings. In November 2010, ANACOM issued a final decision regarding the registration of objects in the SIC and the terms and formats for providing information for the SIC. Other elements, such as the terms upon which objects will be geographically defined through the combination of their administrative location and georeferencing, are also set forth.

Since PT Comunica¸coes already has a reference offer under which it is required to provide a ˜ substantial amount of information to operators that wish to use its ducts and associated infrastructure, we are paying close attention to the implementation of the SIC, since we do not wish for the SIC to compound PT Comunica¸coes's obligation to provide information regarding its ducts and associated ˜ infrastructure.

Decree-Law No. 123/2009 also contained a rule regarding installing wiring in existing buildings, in which it was set forth that the first operator entering an existing building to adapt its telecommunications infrastructure to optic fiber is obligated to adapt the infrastructure to allow sharing with other electronic communications companies that wish to provide electronic communications services based on fiber. This rule ceased to be in effect on January 1, 2010 with the entering into force of the second edition of the technical rules and norms for infrastructure of telecommunications in buildings (ITED 2nd Edition). Under the ITED 2nd Edition, the first electronic communications undertaking entering a building with fiber remains obligated to install fiber optic wiring in order to allow sharing with other operators. However, ITED 2nd Edition only sets forth the technical rules that apply to installing wiring and does not solve other problems, such as those related to cost sharing, relationships of operators with the buildings' owners or management and technical harmonization needed within the sharing of the infrastructure.

Number Portability and Carrier Selection

Number portability allows a subscriber at a specific location to change service providers without having to change telephone numbers. Under ANACOM regulations, we are required to allow number portability for both fixed line and mobile services. From October through December 2011, ANACOM undertook a public consultation on amending existing number portability regulations to, among other things, ensure fixed and mobile number portability within one working day and to make other changes favorable to subscribers. The final regulation was adopted in March 2012 and will enter into force on September 13, 2012.

ANACOM has required call-by-call carrier selection to be offered by us for long distance and international calls since 2000. We have been offering it for local and regional calls since 2001 and for fixed-to-mobile calls since 2000. Call-by-call carrier selection enables customers to select the carrier of their calls by dialing a code connecting them to the selected carrier.

Law 5/2004 requires that all fixed line network operators with significant market power must offer carrier pre-selection. Carrier pre-selection allows customers to select the carrier that will be their default carrier. This removes the need for customers to dial any code to connect to their selected carrier when making calls. Full carrier pre-selection has been available throughout Portugal since 2000.

Unbundling of the Local Loop

In 2000, the European Commission approved a regulation requiring fixed line network operators to make the local loops between their customers and the local switches on their networks available to competitors. Such a requirement also appears in Law 5/2004. This allows such competitors to connect their networks to the copper ''local loop'' and use it to provide their services directly to those customers without having to invest in the local loop or to rely upon the network operator's relationship with the customers. According to the regulation and Law 5/2004, we are required to maintain a reference offer for unbundled access to our local loops and related facilities and to meet reasonable requests for unbundled access to our local loops and related facilities under transparent, fair and non-discriminatory conditions. Prices charged must be cost-oriented. The conditions under which the local loop unbundling services are provided are set forth in a published reference offer for unbundled access to our local loops in accordance with terms established by ANACOM. This reference offer covers all of our main distribution framework buildings where technical and space conditions allow

co-location. Co-location means providing space and technical facilities to competitors to the extent necessary to reasonably accommodate and connect the relevant equipment of the competitor.

Internet and Related Services

Various regulatory developments may affect our Internet business. A Data Protection Directive was adopted by the European Commission in 2006, imposing data-retention obligations on operators. A law implementing this directive was published in 2008 and requires Internet service providers and other electronic communications providers to preserve data for a specified period of time and imposes other obligations in this field.

Roaming

The European Commission has determined that roaming prices in Europe should be reduced and has published new regulations that have been in effect since 2007. These regulations set maximum roaming charges that may be charged in the wholesale market and the retail market. In 2008, the European Commission launched a consultation on roaming, proposing to carry over Regulation (EC) No. 717/2007, on roaming on mobile communications networks within the community (the ''Roaming Regulation''), beyond 2010 and to extend it to data and Short Messaging Services (''SMS''), or text messaging. In 2009, Regulation (EC) No. 544/2009, amending the Roaming Regulation (the ''New Roaming Regulation''), went into effect, limiting roaming charges. The New Roaming Regulation aimed to reduce roaming charges by up to 60%. The European Commission also requested clarification from operators with respect to price differences between data services while roaming compared to prices in the domestic market.

Under the New Roaming Regulation, voice roaming rates in the retail market continue to be subject to a glide path (prices excluding VAT): from July 1, 2010, maximum rates of A0.39 per minute for outgoing and A0.15 per minute for incoming roaming calls; and from July 1, 2011, maximum rates of A0.35 per minute for outgoing and A0.11 per minute for incoming roaming calls. In the wholesale market, maximum rates were set at A0.22 and A0.18 as of July 1, 2010 and July 1, 2011, respectively. For SMS services, caps of A0.11 in the retail and of A0.04 in the wholesale came into force on July 1, 2009. For data services, maximum wholesale rates of A0.80 and A0.50 applied from July 1, 2010 and July 1, 2011, respectively.

The New Roaming Regulation is due to expire on June 30, 2012 and to be replaced by a third version, known as ''Roaming III.'' The European Commission has proposed revisions to certain of those standards, including (1) a cap on retail data tariffs, proposed for July 2012, (2) introduction of an obligation for mobile operators to provide network access in order to allow roaming services, proposed for July 2012, and (3) the decoupling of roaming services from other services, while enabling a consumer to use the same number, proposed for July 2014. We expect the European Commission to make a final decision on these proposals in May 2012.

Other Requirements

The regulatory framework requires PT Comunica¸coes to submit periodic reports on quality of ˜ service and comply with specified indicators. Penalties may occur if we do not achieve such indicators. We must also provide white page directories and certain other facilities to certain specified categories of subscribers free of charge.

Licensing Framework

The EU Authorization Directive (Directive 2002/20/EC of March 7, 2002) prohibits any limitation on the number of new entrants in telecommunications markets, except as required to ensure an efficient use of radio frequencies.

Pursuant to this directive, which is part of the EU electronic communications framework, Law 5/2004 has established an authorization regime whereby an operator must have a general authorization for the provision of electronic communications networks or services. A license can be required for the use of radio frequencies or numbering resources. ANACOM is responsible for issuing regulations to implement this authorization regime. The objective of this new authorization regime is to introduce more flexibility into the licensing framework.

Summary of Our Concession and Existing Licenses and Authorizations

Our concession is for the provision of universal service and for the operation of the terrestrial broadcasting network in Portugal, and it permits us to provide public switched fixed line telephone, packet switched data in X.25 mode, leased lines and telex and telegraphy services in Portugal. We also operate a digital terrestrial television platform and provide mobile telephone services, data communications services and television distribution services under the licenses granted and authorizations issued to our subsidiaries by the relevant authorities (the Portuguese government and ANACOM). The subsidiaries holding the licenses and authorizations are subject to separate financial reporting and other requirements.

Our Fixed Line Concession. The Portuguese government granted us a concession on March 20, 1995. The concession had an initial term of 30 years, expiring in 2025. As part of a reorganization of our business, we transferred the concession to our subsidiary PT Comunica¸coes in 2000. The concession ˜ granted us the right to install, manage and operate the infrastructure that forms part of the basic telecommunications network and the terrestrial broadcasting network for a fee of up to 1% of our operating revenues from the services provided under the concession, after certain deductions. Some of our assets that are part of the basic telecommunications network (as defined in Portuguese legislation) were treated as being within the ''public domain'' under the terms of the concession. During the term of the concession, we were permitted to receive economic benefits from the use of public domain assets as if we owned them completely. However, such public domain assets would have reverted to the Portuguese government without compensation when the concession expired.

In December 2002, we agreed to prepay the future rental payments due under the concession in exchange for full ownership of the basic telecommunications network and to ensure that there will be no reversion of the assets related to the provision of concession services to the government in 2025. We acquired full ownership of the basic telecommunications network for A365 million, which included the 2002 concession fee of A16.6 million. As a result of this acquisition, the terms of the concession have been modified so that PT Comunica¸coes is no longer obligated to pay a concession fee to the ˜ Portuguese government, and ownership of the network and assets related to the concession will not revert back to the Portuguese government in 2025. In 2003, Decree Law 31/2003 was enacted, establishing the basic regulatory principles supporting the terms of our modified Concession. Later that year, we entered into an agreement formally modifying the terms of our concession with the Portuguese government.

The Portuguese government retains the ability to suspend or terminate our rights under the concession. In cases of serious non-fulfillment by us of our obligations under the concession, the Portuguese government may, on a provisional basis, take over the development and operation of services authorized under the concession. The concession may also be terminated in cases of ''severe, continual or unremedied'' failure to perform our obligations. We believe that we have the resources to fulfill all our obligations under the concession.

In addition, the Portuguese government may revoke the concession upon at least one year's notice if it deems such action to be justified in the public interest. If this occurs, we would be entitled to compensation equaling our annual average net profits for the five years prior to notification of revocation multiplied by the number of years remaining before the concession expires.

Our modified concession provides that we are exempt from all taxes, fees and charges with respect to the usage of public rights-of-way for our telecommunications infrastructure. However, Law 5/2004 establishes a new rights-of-way regime in Portugal whereby each municipality may establish a fee, up to a maximum of 0.25% of each wireline services bill, to be paid by the customers of those wireline operators whose network infrastructures are located in each such municipality. This regime was implemented in 2005. The new regime replaces Law 91/97, which granted us an exemption from municipal taxes and rights-of-way and other fees with respect to access to and installation and use of our telecommunications network in connection with our obligations under the concession. Our exemption from municipal taxes prior to the enactment of Law 91/97 is still being challenged in court. See ''Item 8—Financial Information—Legal Proceedings—Claims for Municipal Taxes and Fees.''

Our concession imposes universal service obligations on us. See ''—Universal Service Obligations'' above.

The Ministry of Finance is responsible for monitoring financial issues with respect to the concession. The Ministry of Economy is responsible for all other issues under the concession. ANACOM is authorized to monitor and assess penalties up to a maximum of A5 million if we fail to fulfill our obligations under the concession or other obligations imposed by law or stemming out of ANACOM's determinations. Disputes concerning the application and interpretation of the concession are dealt with by arbitration.

Our Fixed Line and Data Licenses. We also hold the following licenses:

• a non-exclusive license to provide fixed line telephone services;
• a non-exclusive license to be a ''Public Telecommunications Networks'' operator; and
• all the licenses formerly held by Telepac, including a data communications license.

Our data communications license authorizes us to provide X.25/X.32 synchronous services and X.28 asynchronous services and other switched and non-switched data communications services, including frame relay and virtual private networks for data communications. The license also authorizes us to provide value-added services such as electronic data interchange and videotext services. In addition, the license authorizes us to construct certain network infrastructure in connection with licensed services. With respect to packet switched data, the data communications license is valid for 30 years, unless our wireline concession is terminated earlier Licenses have also been granted to other providers of data communications and Internet access services, including companies associated with major international telecommunications providers. However, under Law 5/2004, and in accordance with the EU licensing regime, companies are not required to have a license to provide data communications services and Internet access. Instead, it is sufficient to register their intended services with ANACOM under its service registration scheme.

Since 1997, we have also held a license to provide data communications services using satellite infrastructure and a license to offer voice services to corporate networks and other closed groups of users.

Digital Terrestrial Television Services. Following a public tender launched by ANACOM in 2008, PT Comunica¸coes was granted the frequency usage rights for Digital Terrestrial Television (''DTT'') ˜ associated with the transport of the signal of free-to-air television channels (the RTP, SIC and TVI broadcast channels), the so-called ''Multiplex A'' or ''Mux A.'' In 2009, the ERC notified us of its final decision to grant us a license to act as a TV distribution operator. On December 22, 2010, ANACOM approved the draft decision regarding the change of the operating channels Mux A of the DTT, assigned to PT Comunica¸coes. ˜

In preparation for the migration to Digital Terrestrial Television in Portugal, three pilot programs were carried out in 2011 in Alenquer, Nazare and Santar ´ em, Portugal. The switch-off of the analog ´ television network in Portugal occurred on April 26, 2012.

TMN's Mobile Service License. Mobile telephone service licenses are valid for 15 years and are issued by ANACOM under Law No. 5/2004. These licenses authorize the use of radio spectrum and the installation of base stations, base station controllers and control switching centers and require the licensee to construct networks capable of reaching at least 75% of Portugal's population within a specified period of time. Charges for the provision of mobile telephone services are not subject to regulation.

Through TMN, we hold a renewable license to provide traditional and GSM digital mobile telephone services throughout Portugal. The authorization for the use of GSM radio spectrum was renewed in March 2007 and is now valid until March 16, 2022. Two other operators hold licenses to provide GSM digital mobile telephone services on substantially the same terms as those applicable to TMN. Vodafone Portugal was awarded its license in 1991. Optimus was awarded a license in 1997 and began operations in September 1998.

We are required to comply with a number of mobile telephone service criteria. These include satisfying minimum quality standards regarding blocked call rates, network effectiveness and servicing time, and providing certain services. We are also required to provide ANACOM with information about our mobile telephone operations, including the number of customers, number and average duration of calls on a quarterly basis. We are also required to provide annual information to ANACOM about the development of infrastructure.

ANACOM began issuing UMTS licenses in January 2001. UMTS services are the European version of the globally accepted technical standards for ''third-generation'' mobile communications. UMTS constitutes a significant advance over the ''second-generation'' digital GSM mobile services. The ''first-generation'' services were traditional analog mobile services. The broadband capacity of the frequency spectrum allocated under the UMTS licenses enables operators to supply video and Internet content to mobile telephones at higher transmission speeds. The licenses cover all of Portugal and are valid for 15 years. The license fee was A100 million per license. TMN and the other two main mobile operators in Portugal were each awarded one of these licenses at the beginning of 2001, and TMN's license expires in January 2016.

In April 2004, TMN launched UMTS in Portugal with an emphasis on new services, such as video telephony and high-speed data. Since then, TMN has pursued a strategy of gradual improvements to network coverage, using existing GSM sites where possible in order to minimize the need to install costly new sites.

In addition, in 2000, TMN and the other mobile operators assumed commitments to make contributions to the information society during the period through the maturity of the license in 2016. In 2007, pursuant to an agreement between TMN and the Portuguese government, and based on contributions already made, the outstanding commitments were valued at A355 million. Under the agreement, A260 million of this amount was to be spent on ''E Initiatives,'' an initiative led by the Portuguese government to offer to school teachers and students laptops and discounted broadband services. The remaining A95 million was to be spent on subsidies for equipment, service discounts and network investments. Our expenses relating to the A233 million liability recorded in 2007 have been fully reflected in our financial statements, and the only liabilities on our balance sheet relating to our commitments under the terms of TMN's license are liabilities in the ordinary course of our business.

In July 2010, ANACOM decided, within the context of the 900/1800 MHz spectrum refarming process, to unify into a single authorization the conditions applicable to the rights of use of frequencies allocated to TMN for the provision of the land mobile service, in accordance with GSM 900/1800 and UMTS technologies. The authorization is valid until March 16, 2022.

In 2011, ANACOM launched an auction for the allocation of rights of use of frequencies in the 450, 800, 900, 1800 MHz and 2.1 and 2.6 GHz bands. Following that auction, on March 9, 2012, ANACOM issued the final renewable license to TMN, allowing the provision of electronic communications services based, among others, on LTE (Long Term Evolution) technology. This license is valid until March 2027, and it also unifies the previous GSM and UMTS licenses issued by ANACOM. Licenses were also issued to Optimus and Vodafone.

Brazil

Overview

Oi's business, including the nature of the services it provides and the rates it charges, is subject to comprehensive regulation under the Brazilian General Telecommunications Law (Lei Geral das Telecomunica¸coes ˜ ) and a comprehensive regulatory framework for the provision of telecommunication services promulgated by ANATEL. Oi provides fixed-line, domestic and international long-distance and mobile telecommunication services under concessions, authorizations and licenses that were granted by ANATEL and allow it to provide specified services in designated geographic areas, as well as set forth certain obligations with which it must comply.

ANATEL is a regulatory agency that was established in July 1997 pursuant to the General Telecommunications Law and the Regulamento da Agˆencia Nacional de Telecomunica¸coes ˜ . ANATEL oversees Oi's activities and enforces the General Telecommunications Law and the regulations promulgated thereunder. ANATEL is administratively independent and is financially autonomous. ANATEL is required to report on its activities to the Brazilian Ministry of Communications. ANATEL has authority to propose and to issue regulations that are legally binding on telecommunication service providers. ANATEL also has the authority to grant concessions and licenses for all telecommunication services, other than broadcasting services. Any regulation or action proposed by ANATEL is subject to a period of public comment, which may include public hearings, and ANATEL's decisions may be challenged administratively before the agency itself or through the Brazilian judicial system.

Concessions and Authorizations

Under the General Telecommunications Law and ANATEL regulations, the right to provide telecommunication services is granted either through a concession under the public regime or an authorization under the private regime. A concession is granted for a fixed period of time following a public auction and is generally renewable only once. An authorization is granted for an indeterminate period of time and public auctions are held for some authorizations. These concessions and authorizations allow service providers to provide specific services in designated geographic areas, set forth certain obligations with which the service providers must comply and require equal treatment of customers by the service providers.

The four principal providers of fixed-line telecommunication services in Brazil (Telemar, Oi, Telesp and Embratel) provide these services under the public regime. In addition, CTBC and Sercomtel, which are secondary local fixed-line telecommunication service providers, operate under the public regime. All of the other providers of fixed-line telecommunication services and all providers of personal mobile services and data transmission services in Brazil operate under the private regime.

Providers of public regime services, such as Oi, are subject to more obligations and restrictions than providers of private regime services. Under Brazilian law, providers of public regime services are subject to certain requirements with respect to services such as quality of service, continuity and

universality of service, network expansion and network modernization. Additionally, the rates that public regime service providers may charge customers are subject to ANATEL supervision.

Regulation of Fixed-Line Services

Public Regime Concessions

Each of the public regime service providers operates under concession agreements that expire in December 2025. Under these new concession agreements, each of the public regime service providers is required to comply with the provisions of (1) the General Plan on Universal Service that was adopted by ANATEL in June 2003, (2) the General Plan on Quality Goals that was adopted by ANATEL in June 2003, and (3) the General Plan on Competition Targets which, as of the date of this annual report, has not yet been adopted by ANATEL. The General Plan on Competition Targets was submitted for public consultation in July 2011 and the public consultation period ended on October 23, 2011. Oi expects these new regulations, as they may be modified as a result of ANATEL's further analysis, to be adopted in 2012.

The concession agreements provide that ANATEL may modify their terms in 2015 and 2020 and may revoke them prior to expiration under some specific circumstances provided for by law and the concession agreements. The modification right permits ANATEL to impose new terms and conditions in response to changes in technology, competition in the marketplace and domestic and international economic conditions. ANATEL is obligated to engage in public consultation in connection with each of these potential modifications.

ANATEL may also terminate the concessions upon the occurrence of certain events, such as an extraordinary situation jeopardizing the public interest, a provider's material failure to comply with its universalization targets or insurance requirements. In the event a concession is terminated, ANATEL is authorized to administer the provider's properties and its employees in order to continue rendering services.

Rate Regulation

Public regime service providers must offer a basic service plan comprised of the following basic services: (1) installation, (2) monthly subscription and (3) switched local minutes. Modifications of the rates charged for these basic services are determined by reference to a local rate basket that represents the weighted average of the rates for monthly subscriptions and switched local minutes. Rates for long-distance services originated and terminated on fixed lines vary in accordance with specified criteria. Modifications of the rates charged for these long-distance services are determined by reference to a long-distance rate basket that represents the weighted average of the rates for long-distance calls. The rates for international long-distance services charged by long-distance service providers other than Embratel, including Oi, all of whom provide these services under authorizations rather than concessions, are not subject to ANATEL regulation.

The concession agreements establish a price-cap mechanism for annual rate adjustments for basic service plans and domestic long-distance rates based on formulas set forth in each provider's concession agreement. The formula provides for two adjustments to the price cap based on the local rate basket, the long-distance rate basket and the use of a price index. The price cap is first revised upward to reflect increases in inflation, as measured by an index, then ANATEL applies a productivity discount factor, or Factor X, which reduces the impact of the rate readjustment provided by the index.

ANATEL has proposed new regulations under which it would modify the Factor X applicable to the determination of rate increases available to public concessionaires providing fixed-line services. These regulations were submitted for public consultation in July 2011 and the public consultation period ended on September 1, 2011. Oi expects these new regulations, as they may be modified as a result of ANATEL's further analysis, to be adopted in 2012.

Unbundling of Local Fixed-Line Networks

On May 2004, ANATEL issued an order establishing rules for partial unbundling of the local fixed-line networks of the public regime service providers, which we refer to as ''line sharing,'' and requiring the eventual full unbundling of local fixed-line networks, which will entail these providers making their entire networks available to other telecommunication service providers.

As of the date of this annual report, ANATEL has not yet adopted final unbundling rules or rates for full unbundling, although ANATEL has proposed a General Plan on Competition Targets, which addresses a variety of matters, including regulations related to partial unbundling and/or full unbundling of the local fixed-line networks of the public regime service providers. The General Plan on Competition Targets was submitted for public consultation in July 2011 and the public consultation period ended on October 23, 2011. Oi expects these new regulations, as they may be modified as a result of ANATEL's further analysis, to be adopted in 2012. Oi expects that the rates that it would receive from other telecommunication services providers accessing its fixed-line networks under these regulations, if adopted, will be lower than the rates Oi currently charges its customers for providing fixed-line and broadband internet services.

Service Restrictions

Pursuant to regulations in effect as of the date of this annual report, public regime providers are subject to certain restrictions on alliances, joint ventures and mergers and acquisitions with other public regime providers, including:

• a prohibition on holding more than 20% of the voting shares of more than one other provider of public regime services; and
• a restriction on mergers between regional fixed-line service providers.

In December 2010, ANATEL adopted new regulations eliminating the limitation on the number of authorizations to provide subscription television services. In September 2011, the Brazilian congress passed Law No. 12,485, which was signed into law by the President of Brazil in September 2011. Law No. 12,485 creates a new legal framework for subscription television services in Brazil, replacing and unifying the previously existing regulatory provisions that governed various forms of subscription television services, such as cable television, Multichannel Multipoint Distribution Service (''MMDS'') and DTH. The principal provisions of Law No. 12,485:

• allow fixed-line telephone concessionaires, such as us, who previously were allowed to provide subscription television services using only MMDS and DTH technologies, to enter the cable television market in Brazil;
• remove existing restrictions on foreign capital investments in cable television providers;
• establish minimum quotas for domestic content programming on every television channel;
• limit the total and voting capital held by broadcast concessionaires and authorized providers, and in television programmers and producers, with headquarters in Brazil to 30%; and
• prohibit telecommunications service providers with collective interests from acquiring rights to disseminate images of events of national interest and from hiring domestic artistic talent.

The framework established by Law No. 12,485 is expected to increase the availability and lower the price of subscription television services in Brazil through increased competition among providers and is expected to improve the quality, speed and availability of broadband internet services as a result of the expected proliferation of fiber optic cables used to transmit cable television.

In March 2012, ANATEL adopted new regulations under which the authorizations to provide various existing subscription television services have been consolidated into authorizations to provide a newly-defined service called Conditional Access Service. Under these regulations, authorizations to provide Conditional Access Service will apply to private telecommunications services, the receipt of which are conditioned on payment by subscribers, for the distribution of audiovisual contents in the form of packages, individual channels and channels with required programming, by means of any communications technology, processes, electronic means or protocols. An authorization granted by ANATEL to provide Conditional Access Service will be valid for the entire Brazilian territory, but the provider must indicate in its application for an authorization the localities that it will service.

Regulation of Mobile Services

In September 2000, ANATEL adopted regulations that established operating rules for providers under the personal mobile service (Servi¸co Movel Pessoal ´ ) regime. The regulations permitted ANATEL to grant authorizations to provide mobile telecommunication services under the personal mobile service regime. For purposes of the personal mobile service regulations, Brazil is divided into three service regions covering the same geographic areas as the concessions for fixed-line telecommunication services.

Auction of Personal Mobile Services Spectrum

Prior to the establishment of the personal mobile services regime, ANATEL had granted licenses to mobile services providers to operate in each region of Brazil using Bands A and B. In 2001 and 2002, ANATEL successfully auctioned authorizations and licenses to operators in Band D and Band E in each region. TNL was granted its initial authorization to provide personal mobile services in Region I and a license to operate in Band D in March 2001. Brasil Telecom's subsidiary Brasil Telecom Celular S.A. (''Brasil Telecom Mobile'') was granted its initial authorization to provide personal mobile services in Region II and a license to operate in Band E in December 2002.

ANATEL conducted additional auctions of radio frequency licenses in 2004 and 2006. In April 2004, Brasil Telecom Mobile acquired an additional license to operate in Region II.

In December 2007, ANATEL auctioned the remaining spectrum of Bands A, B, C, D and E to existing service providers as extension blocks and auctioned additional spectrum in Band M (1.8 GHz) and Band L (1.9 GHz). In these auctions, TNL acquired (1) an authorization to provide personal mobile services in the State of Sao Paulo and licenses to operate using Band M throughout the State of ˜ Sao Paulo and Band E outside of the city of S ˜ ao Paulo, and (2) licenses to use additional spectrum in ˜ 12 states in Region I.

Auction of 3G Spectrum

In preparation for auctions of spectrum in Bands F, G, I and J (2.1 GHz), the use of which allows personal mobile services providers to offer 3G services to their customers, ANATEL issued regulations that divide the Brazilian territory into nine regions for purposes of operations using these frequency bands. In December 2007, ANATEL auctioned radio frequency licenses to operate on each of these frequency bands in each of the nine regions and the related licenses to use these frequency bands. In this auction, Brasil Telecom acquired the radio frequency licenses necessary to offer 3G services in two of the nine regions delineated by ANATEL for 3G services (corresponding to Region II under the personal mobile services regime) and TNL acquired radio frequency licenses necessary to offer 3G services in six of the nine regions delineated by ANATEL for 3G services (corresponding to Regions I and III under the personal mobile services regime, other than an area that consists of 23 municipalities in the interior of the State of Sao Paulo that includes the city of Franca and surrounding areas). ˜

Authorizations to Use 450MHz Band and 2.5 GHz Band

Under Executive Decree 7,512, dated June 30, 2011, or Executive Decree 7,512, ANATEL is required to grant authorizations to telecommunications providers to use radio spectrum in the 450 Mhz band radio spectrum and the 2.5 GHz radio spectrum in the second quarter of 2012. Among other obligations, licensees of radio frequencies in the 450 Mhz band radio spectrum must agree to provide individual and collective voice and data services in rural and remote areas, in accordance with the provisions of Executive Decree 7,512 and the General Plan on Universal Service. The rules of the auctions for radio frequency spectrum in the 450 Mhz band and 2.5 GHz band and the terms of the related authorizations were submitted for public consultation and the public consultation period ended on March 5, 2012. ANATEL is expected to announce the terms of the auctions for radio frequency spectrum in the 450 Mhz band and 2.5 GHz band in late April 2012. Oi intends to evaluate its participation in these auctions following the announcement of the terms of these auctions.

Personal Mobile Services Rate Regulation

Rates for personal mobile services are regulated by ANATEL. Personal mobile services providers are required to offer a basic service plan that consists of a monthly subscription, local calls and roaming. Basic service plans were approved by ANATEL for each of the personal mobile services providers following the grant of personal mobile services authorizations to each of these providers.

Personal mobile services providers are permitted to offer non-discriminatory alternative plans to the basic service plan. The rates charged under these plans (e.g., monthly subscription rates, charges for local calls and roaming charges) are subject to ANATEL approval prior to the time that these plans are first offered to mobile customers. Following the approval of these plans, the rates under these plans may be increased up to an annual adjustment that is approved by ANATEL and is no more than the rate of inflation, as measured by the IST.

Although subscribers of a plan cannot be forced to migrate to new plans, existing plans may be discontinued as long as all subscribers receive a notice to that effect and are allowed to migrate to new plans within six months of such notice. Discounts from the rates set in basic service plans and alternative service plans may be granted to customers without ANATEL approval.

Interconnection Regulations

Under the General Telecommunications Law, all telecommunication service providers are required, if technically feasible, to make their networks available for interconnection on a non-discriminatory basis whenever a request is made by another telecommunication service provider. Interconnection permits a call originated on the network of a requesting fixed-line or personal mobile services provider's network to be terminated on the fixed-line or personal mobile services network of the other provider. ANATEL initially adopted General Rules on Interconnection (Regulamento Geral de Interconexao˜ ) in 1998, which were amended and restated in July 2005.

Interconnection Regulations Applicable to Fixed-Line Providers

Interconnection fees are charged at a flat rate per minute of use of a fixed-line provider's network. Interconnection rates charged by a fixed-line provider to terminate a call on its local network (the ''TU-RL rate'') or intercity network (the ''TU-RIU rate'') are subject to a price cap established by ANATEL. The price cap for interconnection rates varies from service provider to service provider based on the underlying cost characteristics of such service provider's network and whether such service provider has significant market power.

Fixed-line service providers must offer the same TU-RL and TU-RIU rates to all requesting providers on a nondiscriminatory basis. The price caps on interconnection rates are adjusted annually by ANATEL at the same time that rates for local and long-distance rates are adjusted. Fixed-line service providers are only required to pay interconnection fees to another fixed-line service provider for traffic in the same local area in the event that the ratio of the outbound traffic generated by that provider (measured in minutes) to the inbound traffic terminated by that provider (measured in minutes) exceeds 55% or was less than 45%. This system is designated the ''bill-and-keep'' system.

In 2007, ANATEL announced that, beginning in 2008, the method used to determine the TU-RL rates would be based on a long-run incremental cost (''LRIC'') methodology. However, later in 2007, ANATEL published an official letter delaying this change until the end of 2010. In 2010, ANATEL commenced the bidding process to engage an international consultant to assist with the development of the LRIC methodology. However, ANATEL has not established a definitive timetable for the completion of the project. Therefore, Oi cannot predict when this new methodology will be proposed.

In 2006, the TU-RIU rates that fixed-line service providers could charge each other to use a portion of their long-distance networks to complete long-distance calls were reduced to 30% of the applicable domestic fixed line-to-fixed line long-distance rates for calls of more than 300 km.

Interconnection Regulations Applicable to Personal Mobile Services Providers

Interconnection fees are charged at a flat rate per minute of use of a personal mobile services provider's network. The terms and conditions of interconnection agreements of all personal mobile services providers, including the rates charged by the operator of the network to terminate a call on its mobile network (the ''VU-M rate''), commercial conditions and technical issues, are freely negotiated between mobile and fixed-line telecommunication service providers, subject to compliance with regulations established by ANATEL relating to traffic capacity and interconnection infrastructure that must be made available to requesting providers, among other things.

If the providers cannot agree upon the terms and conditions of interconnection agreements, ANATEL may determine terms and conditions by arbitration. Since no agreement with fixed-line service providers could be reached regarding VU-M rates when Oi began offering personal mobile services, ANATEL set the initial VU-M rates. Personal mobile services providers also negotiate annual rate increases for their VU-M charges with the fixed-line telecommunications providers. If the providers cannot agree upon the terms and conditions of annual rate increases, ANATEL may determine the annual rate increases by arbitration. Personal mobile services providers must offer the same VU-M rate to all requesting providers on a nondiscriminatory basis. Interconnection agreements must be approved by ANATEL before they become effective, and they may be rejected if they are contrary to the principles of free competition and the applicable regulations.

In November 2011, ANATEL adopted new regulations under which ANATEL was authorized to reduce the then-current VC-1, VC-2 and VC-3 rates by as much as 18% in 2011, 12% in 2012 and 10% in 2013, after giving effect to an inflation adjustment based on the IST measured from June 2009. In February 2012, ANATEL reduced our VC-1, VC-2 and VC-3 rates by approximately 10%, although Oi is appealing the calculation of this rate reduction. These regulations also provided procedures under which ANATEL adopted a maximum VU-M rate that is applicable in the event that providers cannot agree upon the VU-M applicable in their interconnection agreements.

''Full Billing'' System

In July 2006, ANATEL adopted new regulations under which personal mobile services providers recognize interconnection revenues (and costs) for traffic in the same registration area on a gross basis based on the total traffic between personal mobile services providers' networks. This system is designated the ''full billing'' system.

Regulation of Interconnection Rates Charged by Providers with Significant Market Power

In 2005, ANATEL issued regulations defining a series of cost-based methods, including the fully allocated cost methodology, for determining interconnection fees charged by telecommunications service providers belonging to economic groups with significant market power based on their fixed-line or personal mobile services interconnection networks. All incumbent fixed-line service providers and all personal mobile services providers are deemed by ANATEL to belong to economic groups with significant market power in their respective service areas until ANATEL finalizes its evaluation of each provider under published criteria to determine significant market power.

In July 2006, ANATEL issued regulations regarding the fees that may be charged for the use of mobile networks by personal mobile services providers with significant market power in the mobile interconnection market. The date on which these regulations will become effective has not yet been established by ANATEL. Under these regulations, ANATEL will determine, based on a fully allocated cost model, a reference value for VU-M rates of providers that are deemed to hold significant market power, which is determined based on specified factors. This reference value will be reassessed every three years.

ANATEL has proposed a General Plan on Competition Targets, which addresses a variety of matters, including criteria for the evaluation of telecommunications providers to determine which providers have significant market power. The General Plan on Competition Targets was submitted for public consultation in July 2011 and the public consultation period ended on October 23, 2011. Oi expects these new regulations, as they may be modified as a result of ANATEL's further analysis, to be adopted in 2012.

Regulation of Data Transmission and Internet Services

Under Brazilian regulations, ISPs are deemed to be suppliers of value-added services and not telecommunication service providers. Telecommunication service providers are permitted to render value-added services through their own networks. In addition, ANATEL regulations require all telecommunications service providers and cable television operators to grant network access to any party interested in providing value-added services, including internet access, on a non-discriminatory basis, unless not technically feasible.

ANATEL has adopted regulations applicable to fixed-line service providers with significant market power. Under these regulations, these providers are required to make the forms of agreements that they use for EILD and SLD services publicly available, including the applicable rates, and are only permitted to offer these services under these forms of agreement. Following publication of these forms of agreement, the rates under these agreements may be increased on an annual basis by no more than the rate of inflation, as measured by the IST. ANATEL also publishes reference rates for these services.

Multimedia Communications Service Quality Management Regulations

In June 2011, the President of Brazil issued Executive Decree No. 7,512/11, which mandated ANATEL to take the necessary regulatory measures to establish quality standards for broadband internet services. In compliance with such decree, on October 31, 2011, ANATEL published a resolution approving the Multimedia Communications Service Quality Management Regulations (Regulamenta¸cao de Gest ˜ ao da Qualidade do Servi¸ ˜ co de Comunica¸cao Multim ˜ ´ıdia, or the ''Regulations''), which identify network quality indicators and establish performance goals for multimedia communications service providers, including broadband internet service providers, with more than 50,000 subscribers. Such providers will be required to collect representative data using dedicated

equipment installed at the site of each network connection and be subject to periodic measurements to ensure their compliance with the Regulations, including:

• individual upload and download speeds of at least 20%, 30% and 40% of contracted speeds per measurement for at least 95% of all measurements, during the first year, second year and thereafter, respectively, following implementation of the Regulations;
• average upload and download speeds of at least 60%, 70% and 80% of contracted speeds for all measurements during the first year, second year and thereafter, respectively, following implementation of the Regulations; and
• individual round-trip latencies for fixed-line connections of up to 80 milliseconds per measurement for at least 95% of the measurements.

To increase transparency, customers must be provided with specialized software at no cost to measure their own network quality, although such customer-generated measurements will not be included in official calculations. In addition to ensuring network quality standards, service providers must hire specialized companies to measure customer service and customer satisfaction indicators, including complaint resolution, customer service personnel competence, customer perceptions relating to billing and quality of technical support staff. Service providers must comply with the abovementioned quality standards beginning on the thirteenth month following implementation of the Regulations. Failure to meet such standards will subject non-compliant service providers to sanctions.

National Broadband Plan

On June 30, 2011, Oi entered into a Term of Commitment (Termo de Compromisso) with ANATEL and the Ministry of Communications to formalize its voluntary commitment to adhere to the terms of the National Broadband Plan, created in May 2010 by Executive Decree No. 7,175/10 with the goal to make broadband access available at low cost, regardless of technology, throughout Brazil. Pursuant to the Term of Commitment, Oi is required to offer (1) broadband services with minimum upload and download capabilities to retail customers in certain sectors of Region I and II for a maximum price of R\$35 per month (or R\$29.90 in ICMS-exempt states), plus fees, and (2) access to its broadband infrastructure to certain wholesale customers, including small businesses and municipalities, in certain sectors of Region I and II for a maximum price of R\$1,253 per 2 Mbps per month and a one-time installation fee, while observing all quality standards under ANATEL regulations. Both retail and wholesale services are subject to certain network capacity limits and need only be provided at the demand of the customer. The services provided under the Term of Commitment may be implemented gradually, beginning in November 2011, although Oi is obligated to make services available to 100% of eligible retail and wholesale customers by December 31, 2014 and June 30, 2013, respectively. The Term of Commitment will expire on December 31, 2016.

ITEM 4A—UNRESOLVED STAFF COMMENTS

None.

ITEM 5—OPERATING AND FINANCIAL REVIEW AND PROSPECTS

You should read the following discussion in conjunction with our audited consolidated financial statements and the accompanying notes included elsewhere in this report. Our audited consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (''IFRS''), as adopted by the European Commission for use in the European Union. As of and for the years ended December 31, 2009, 2010 and 2011, there was no difference between IFRS, as adopted by the European Commission for use in the European Union, as applied by Portugal Telecom, and IFRS as issued by the International Accounting Standards Board.

Overview

Our Segments and Customer Categories

Portugal Telecom, SGPS, S.A. is a group holding company. Our business operations are conducted by our subsidiaries and jointly controlled entities, which are classified for financial reporting purposes according to the manner in which our management views and manages our operations.

We operate in two reportable segments: (1) Telecommunications in Portugal and (2) Telecommunications in Brazil-Oi. We report revenues from the Portuguese telecommunications business in four customer categories: (i) residential, (ii) personal, (iii) enterprise and (iv) wholesale and other. In addition to the two reportable segments mentioned above, we have other businesses that do not rise to a threshold that would require disclosure as a reportable segment. Revenues from our Portuguese and international operations accounted for 48% and 52% of our consolidated revenues in 2011, respectively, reflecting primarily 47% and 39% of our consolidated revenues related to the Portuguese and Brazilian (Oi) telecommunications businesses, respectively, as well as 6% of our consolidated revenues related to the proportional consolidation of Contax and 4% of our consolidated revenues related to the Africatel businesses.

• Telecommunications in Portugal. We generate revenues by providing services in the following customer categories:
  • Residential services, which include integrated networks inside the customer's home, enabling the simultaneous connection of multiple devices, including fixed line telephone, TV (including Internet Protocol Television and direct-to-home satellite Pay-TV services), game consoles, PCs, laptops, tablets and smartphones. We provide these services mainly through PT Comunica¸coes. ˜
  • Personal services, which are mobile telecommunications services, such as voice, data and Internet-related multi-media services provided to personal (i.e., individual) customers through our subsidiary TMN.
  • Enterprise services, including Corporate and SME/SoHo services, which provide our corporate and medium and small business customers with data and business solutions, as well as IT/IS and business process outsourcing (BPO) services.
  • Wholesale and other services, which primarily include wholesale telecommunications services, public pay telephones, the production and distribution of telephone directories and other services in Portugal.
• Telecommunications in Brazil—Oi. We completed our investment in Oi on March 28, 2011, and we held a 25.3% economic interest in Oi throughout 2011. Since April 1, 2011, we have proportionally consolidated 25.6% of TmarPart, which, in turn, fully consolidates Oi S.A. and the other Oi Companies. Our economic interest in Oi decreased to 23.25% as a result of a corporate reorganization of Oi that was completed on April 9, 2012. However, our economic interest in TmarPart remains at 25.6%, and therefore we will be permitted to proportionally consolidate 25.6% of TmarPart in 2012, which, in turn, will continue to fully consolidate Oi S.A. and the Oi Companies. Oi generates revenues by providing services in the following customer categories:
  • Residential services, which include local fixed-line services and domestic long-distance services, primarily in Regions I and II of Brazil, data transmission services and usage of Oi's network to complete calls initiated by customers of other telecommunication services providers to Oi's fixed-line network (fixed-line interconnection services).
• Personal services, which include mobile telecommunications services throughout Brazil (Regions I, II and III) utilizing 2G and 3G technology, including voice and data transmission services, and usage of Oi's network to complete calls initiated by customers of other telecommunication services providers to Oi's moblie network (mobile interconnection services).
• Enterprise services, which include fixed-line telecommunications services, mobile telecommunications services, advanced voice services, such as 0800 (toll free) services, customized infrastructure and storage capacity and access to advanced data centers, in each case to corporate and medium and small businesses.
• Other services, which include subscription television services, including cable and DTH television services, ISP services, operation of the iG internet portal (which Oi agreed to sell in 2012) and a mobile phone payment system and call center.
• Other International Telecommunications Businesses. We also generate revenue from our other strategic partnerships in Brazil, Africa and Asia:
  • Contax, Brazil. Concurrently with our investment in Oi, we acquired a direct economic interest of 16.2% in CTX, the parent company of Contax Participa¸coes and Contax, which ˜ provides contact services in Brazil. Even before our investment in Contax, we provided call center services in Brazil through our subsidiary Dedic, and Dedic's subsidiary GPTI provided IT/IS services in Brazil. On June 30, 2011, we exchanged our interest in Dedic and GPTI for an additional interest in Contax, as a result of which Dedic and GPTI became wholly owned subsidiaries of Contax and our economic interest in Contax increased from 14.1% to 19.5%. We have proportionally consolidated the results of operations of Contax in our results of operations since April 1, 2011, based on our direct and indirect interest in CTX (42.0% through June 30, 2011 and 44.4% as from July 1, 2011), and Contax's results of operations have included the results of operations of Dedic and GPTI since July 1, 2011.
  • MTC, Nam´ıbia. We have a 34.0% economic interest in MTC, which provides mobile telecommunications services in Namibia and which we fully consolidate in our audited consolidated financial statements.
  • Cabo Verde Telecom, Cape Verde. We have a 40.0% economic interest in Cabo Verde Telecom, which provides fixed and mobile telecommunications services in the Cabo Verde Islands and which we fully consolidate in our audited consolidated financial statements.
  • CST, Sao Tom ˜ ´e and Pr´ıncipe. We have a 51.0% economic interest in SCT, which provides fixed and mobile telecommunications services in the Sao Tom ˜ e and Pr ´ ´ıncipe Islands and which we fully consolidate in our audited consolidated financial statements.
  • Timor Telecom, East Timor. We have a 41.1% economic interest in Timor Telecom, which provides mobile telecommunications services in East Timor and which we fully consolidate in our audited consolidated financial statements.
• International Equity Investments. We also hold equity interests in strategic partnerships and investments in Africa and Asia:
  • Unitel, Angola. We have a 25.0% economic interest in Unitel, which provides mobile telecommunications services in Angola and which we account for using the equity method.
  • CTM, Macau. We have a 28.0% economic interest in CTM, which provides fixed and mobile telecommunications services in Macau and which we account for using the equity method.

Business Drivers and Measures

The businesses of each of our segments are affected by a number of significant industry trends. In operating our businesses and monitoring their performance, we also pay attention to a number of operational and other factors. We summarize some of these trends and factors for each of our business segments below.

Telecommunications in Portugal

• Increasing Competitive Pressure. Our residential and enterprise businesses face increasingly strong competition from fixed line operators (including VoIP providers) as well as from mobile players. We face aggressive competition from ZON, Sonaecom, Vodafone and other corporate solution operators in the Portuguese telecommunications sector. Our major competitors compete through their respective multi-play offers, which include traditional voice services as well as Pay-TV and broadband Internet services and, on the corporate side, complex telecom and IT/IS solutions.
• Traffic Trends. In recent years, we have experienced a decrease in traffic on our fixed line network, primarily as a result of the trend among consumers to use mobile phones rather than fixed line service and increasing competition from mobile operators, other fixed line operators and, more recently, cable and VoIP providers. This decrease in traffic has negatively affected both our residential and wholesale revenues.
• Changes in Revenue Mix. Our Pay-TV customers have increased since we introduced Pay-TV service in 2008. In addition, our ADSL residential accesses increased by 12.6% in 2011 due to our marketing of service packages that include Pay-TV and ADSL broadband services. The mix of the revenues of our residential business has therefore shifted significantly in recent years, with Pay-TV related revenues partially offsetting the continued pressure on the traditional voice business. In 2010 and 2011, for example, we achieved positive net additions of fixed lines, primarily due to strong performance of Meo double-play and triple-play offers. We expect that Pay-TV and broadband services will continue to be an important driver of our fixed line business, and the architecture and regulation of the developing fiber optic network in Portugal will be an important factor affecting our business and revenues.
• Decreasing Fixed Line Calling Prices and Greater Focus on Pricing Plans. Retail calling prices, particularly for regional, national and international calls, have been decreasing steadily in recent years, which have negatively affected our residential revenues. One of our strategies in response to this trend has been to aggressively market a variety of pricing plans to promote customer loyalty in our competitive market. Our pricing plans tend to increase our revenues from fixed charges but contribute to a decrease in our traffic revenues, particularly with respect to the growing percentage of pricing plans that offer calls at a flat rate. We aggressively use pricing plans for both our residential and personal services.
• Decreasing Interconnection Charges. In 2005, ANACOM declared all mobile operators, including TMN, to have significant market power in call termination in the mobile networks market. As a result, ANACOM imposed price controls on interconnection charges that have caused both fixed-to-mobile and mobile-to-mobile interconnection rates to decrease steadily. In May 2010, ANACOM imposed a glide path that reduced mobile termination rates to A0.035 in August 2011, and in March 2012, ANACOM issued a final decision that will reduce mobile termination rates progressively to A0.0127 by December 2012. These reductions have had, and will continue to have, a significant adverse impact on TMN's revenues and results of operations.
• Continuing Introduction of New Products. The fast development and availability of new access devices are leading to significant growth in Internet users, and more frequent usage, thus leading to increased bandwidth consumption. Examples of this trend are smartphones, tablet PCs and

Internet pads. In 2011, Portugal Telecom continued to develop and introduce a diversified product offering in the mobile market, including touch-screen phones, smartphones and tablet PCs, making available to our customers data and value added services and sophisticated applications and widgets. We describe several of our recently launched services in ''Item 4— Information on the Company—Personal Services—Services.''

• Continuing Investments in our Network. Remaining competitive requires continuing investments to build out our third- and fourth-generation network and develop new services, and our capital expenditures on our network have increased in recent years. In December 2011, we acquired a fourth-generation mobile license, under which TMN will provide services using long term evolution (''LTE'') technology, which represents an evolution from the GSM technology that allows for higher levels of bandwidth and speed.
• Decreases in Wholesale Revenues. In our wholesale business, the decrease in regulated fixed-to-mobile interconnection charges has also affected our revenues because our wholesale wireline unit records revenue from international incoming calls through our network that terminate on the networks of mobile operators. Decreases in transit traffic (calls that use our network but neither originate nor terminate on our network) also have affected our wholesale revenues.

Telecommunications in Brazil—Oi

• Continuing Importance of the Brazilian Market to Our Results of Operations. Although we sold our interest in Vivo to Telefonica S.A. in 2010, we entered into a strategic partnership with Oi, a ´ Brazilian telecommunications company, in 2011. See ''Item 4—Information on the Company—Our Businesses—Brazilian Operations—Strategic Partnership with Oi.'' Under the terms of our strategic partnership, we have a role in the management of Oi, allowing us to share the control of its strategic financial and operating decisions. We proportionally consolidate the results of operations of Oi in our results of operations based on our 25.6% ownership interest in TmarPart, the parent company of Oi S.A. The results of operations of Oi and the dynamics of the Brazilian telecommunications markets are crucial to our financial condition and results of operations.
• Effects of Fluctuations in Exchange Rates. Because we present our financial statements in Euros and must translate Oi's assets, liabilities, results of operations and cash flows from Reais into Euros as of and for each fiscal period, fluctuations in the Euro-Real exchange rate can significantly affect our balance sheet, results of operations and cash flows. In addition, fluctuations in the exchange rate between the Real and the Euro or the U.S. dollar have a significant effect on Oi's own results of operations. Substantially all of Oi's cost of services and operating expenses are incurred in Reais in Brazil. As a result, the appreciation or depreciation of the Real against the U.S. dollar does not have a material effect on Oi's operating margins. However, the costs of a substantial portion of the network equipment that Oi purchases for its capital expenditure projects is denominated in U.S. dollars or is U.S. dollar-linked. This network equipment is recorded on Oi's balance sheet at its cost in Reais based on the applicable exchange rate on the date of the transfer of ownership. As a result, depreciation of the Real against the U.S. dollar results in this network equipment being more costly in Reais and leads to increased depreciation expenses. In addition, a significant portion of Oi's indebtedness is denominated in U.S. dollars or Euros. When the Real appreciates against the U.S. dollar or Euro, Oi's interest costs on its indebtedness denominated in U.S. dollars or Euros declines in Reais, which positively affects its results of operations in Reais, and the amount of Oi's indebtedness denominated in U.S. dollars or Euros declines in Reais. A depreciation of the Real against the U.S. dollar or the Euro has the converse effects.
• Competitive Pressures on Oi's Revenue. Just as we face intense competition in Portugal, Oi's ability to generate revenues from its mobile services business depends on its ability to increase and retain its customer base in the face of significant competition. Similarly, Oi's fixed-line telecommunications services face increasing competition from mobile services as the prices for mobile services in particular regions of Brazil are declining.
• Effects of Expansion of Mobile Data Transmission Services. During 2009, 2010 and 2011, Oi undertook extensive capital expenditure projects to install the network equipment necessary to expand our offerings of 2G and 3G services. Oi expects that these services will generate significant additions to its mobile customer base and lead to long-term increases in its revenues and operating income before financial income (expenses) and taxes. The marketing and promotion campaigns related to Oi's offerings of mobile data transmission services contributed to an increase in the selling expenses of its personal services segment and to an increase in the amount of discounts that Oi recorded against gross operating revenue.
• Effects of Changes in Regulation. Compliance with new regulations applicable to the telecommunications industry that are adopted by ANATEL from time to time and compliance with the obligations included in Oi's concession contracts have required it to make capital expenditures, affected the revenues that Oi generate and imposed additional costs of service on it. For example, on June 30, 2011, TNL entered into a Term of Commitment (Termo de Compromisso) with ANATEL and the Brazilian Ministry of Communications to formalize the voluntary commitment of the Oi Companies to adhere to the terms of the Brazilian National Broadband Plan. Under the Term of Commitment, Oi is obligated, among other things, to make services available to 100% of eligible wholesale customers by June 30, 2013 and retail customers by December 31, 2014.

All our businesses are subject to significant competition and operate in highly regulated environments. You should carefully review ''Item 4—Information on the Company—Competition'' and ''—Regulation'' for more information. In addition, you should be aware of the risks to which each of our businesses is subject. See ''Item 3—Key Information—Risk Factors.''

Seasonality

Although our revenues and costs fluctuate from quarter to quarter, we do not experience large fluctuations due to seasonality. In Portugal; we tend to have higher revenues in the fourth quarter due to promotional campaigns centered on the Christmas holiday. To a lesser degree, promotional campaigns at the time of the Easter and Mother's Day holidays also tend to increase our revenues in the second quarter. In addition, our revenues from our Portuguese operations tend to be lower during the Portuguese summer holidays during the third quarter.

Our telecommunication services in Brazil are generally not affected by major seasonal variations, except for the first quarter of the year, when economic activity is generally reduced in Brazil.

Discontinued Operations—Vivo

On July 28, 2010, we reached an agreement with Telefonica to sell our 50% interest in ´ Brasilcel N.V., a joint venture that held our interest in Vivo, to Telefonica. The sale was concluded on ´ September 27, 2010. Until the sale, we provided mobile telecommunications services in Brazil through Vivo. Our consolidated statements of income and cash flows present Vivo under the caption ''Discontinued Operations'' for all periods, and our consolidated balance sheets as of December 31, 2010 and thereafter no longer include the assets and liabilities related to Vivo.

Limitation on Comparability of Our Financial Statements

Due to the recent significant transactions, our results of operations and other financial information for the years 2009, 2010 and 2011 are not fully comparable.

• Acquisition of ownership interest in Oi. As described above, on March 28, 2011, we acquired a significant economic interest in Oi. Since April 1, 2011, we have proportionally consolidated 25.6% of TmarPart in our consolidated financial statements, which, in turn, fully consolidates Oi S.A. and the other Oi Companies. Our results of operations for 2009 and 2010 do not include the results of operations of Oi and, therefore, are not fully comparable to our results of operations for the year ended December 31, 2011.
• Acquisition of ownership interest in Contax. As described above, at the time of our investment in Oi, we also acquired an interest in Contax. On June 30, 2011, we exchanged our previous investments in Dedic and GPTI for an additional interest in Contax, and as a result our economic interest in Contax increased. We have proportionally consolidated the results of operations of Contax in our results of operations since April 1, 2011, and Contax's results of operations have included the results of operations of Dedic and GPTI since July 1, 2011. For the years ended December 31, 2009 and 2010 and for the period from January 1, 2011 through June 30, 2011, we fully consolidated the results of operations of Dedic in our results of operations. The Contax transaction therefore affects the comparability of our results of operations for the year ended December 31, 2011 with our results of operations for earlier periods.
• Sale of interest in Vivo. As described above, on September 27, 2010, we sold to Telefonica our ´ 50% interest in Brasilcel N.V., a joint venture that held our interest in Vivo. We reflect Vivo in our statements of income and cash flows for periods prior to September 27, 2010 as a discontinued operation. This transaction does not affect the comparability of our results of operations from continuing operations but impacts net income from discontinued operations and, consequently, consolidated net income, which includes the earnings of Vivo in 2009 and up to September 27, 2010. The transaction also let to a significant gain net of related expenses recorded in 2010 in connection with the sale.
• Sale of Interest in UOL—On December 29, 2010, we reached an agreement for the sale to a Brazilian businessman of our 28.78% interest in Universo Online S.A. (''UOL''), Brazil's largest internet provider by revenue for R\$356 million. UOL's total operating revenues were R\$816.7 million in 2010 (A350.5 million) and R\$726.4 million in 2009 (A262.2 million). Our results of operations include the results of operations of UOL only for the years ended December 31, 2009 and 2010, through the equity method of accounting.

Change in Segment Reporting

After we acquired our interest in Oi, we began on April 1, 2011 to report our proportionate interest in the results of operations of Oi, as a separate segment because our management periodically reviews and assesses the performance of Oi on that basis.

In addition, beginning in the third quarter of 2011, we changed the way we report our Portuguese telecommunications businesses. Up to June 30, 2011, we reported two segments in Portugal based on the type of technology used to provide services and products to our customers: Wireline (fixed telecommunication services rendered through PT Comunica¸coes and PT Prime) and Mobile (mobile ˜ telecommunication services rendered through TMN). Because of the progressive integration of fixed line and mobile services and the launch of new bundled products offered to our customers, as from July 1, 2011, our Board of Directors changed the way it reviews and assesses the performance of our businesses in Portugal. We have therefore replaced our former Wireline and Mobile segments with one segment named ''Telecommunications in Portugal,'' which includes all telecommunications services in Portugal. Our discussion of our results of operations for the years ended December 31, 2010 and 2011 reflects this new segment presentation.

Within the Portuguese telecommunications business, we report revenues in four customer categories: residential, personal, enterprise and wholesale and other. To aid comparability of our results of operations, we have provided information on revenues in these customer categories for the year ended December 31, 2010, but we have not done so for the year ended December 31, 2009.

In addition to our two reportable segments, we have other businesses that do not, individually or in the aggregate, exceed any of the quantitive thresholds that would require a disclosure as a reportable segment. These are the businesses we describe above under ''—Our Segments and Customer Categories—Other International Telecommunications Businesses.''

For more information on our segment reporting, see Note 7 to our audited consolidated financial statements.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with IFRS. We summarize our significant accounting policies, judgments and estimates in Note 3 to our audited consolidated financial statements. Our reported financial condition and results of operations are sensitive to accounting methods, assumptions and estimates that underlie preparation of the financial statements. We base our estimates on historical experience and on various other assumptions, the results of which form the basis for judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.

We believe the following critical accounting policies involve the most significant judgments and estimates used in the preparation of our consolidated financial statements.

Property, Plant and Equipment, and Intangible Assets

Accounting for property, plant and equipment, and intangible assets involves the use of estimates for determining the expected useful lives of those assets and the fair value at the acquisition date, in the case of assets acquired in a business combination. The determination of the fair values of assets, as well as of the useful lives of the assets is based on management's judgment.

The determination of impairments of property, plant and equipment, and intangible assets involves the use of estimates that include, but are not limited to, the cause, timing and amount of the impairment. Impairment analysis is based on a large number of factors, such as changes in current competitive conditions, expectations of growth in the telecommunications industry, increased cost of capital, changes in the future availability of financing, technological obsolescence, discontinuance of services, current replacement costs, prices paid in comparable transactions and other changes in circumstances that indicate an impairment exists. The determination of recoverable amounts and fair values are typically based on discounted cash flow methodologies that incorporate reasonable market assumptions. The identification of impairment indicators, the estimation of future cash flows and the determination of fair values of assets (or groups of assets) require management to make significant judgments concerning the identification and validation of impairment indicators, expected cash flows, applicable discount rates, useful lives and residual values. As of December 31, 2011, we concluded that the carrying value of these assets did not exceed their recoverable amounts.

Goodwill

Goodwill arising on consolidation represents the excess of the cost of acquisition over our interest in the fair value of the identifiable assets and liabilities of a subsidiary at the date of acquisition. The assets and liabilities acquired are measured provisionally at the date on which control is acquired, and the resulting value is reviewed in a maximum period of one year from the date of acquisition. Until the fair value of the assets and liabilities has been definitively calculated, the difference between the cost of acquisition and the carrying amount of the company acquired is recognized provisionally as goodwill.

In accordance with IFRS, at the end of each reporting period, we review the goodwill of each cash-generating unit for impairment (i.e., a reduction in its recoverable amount to below its carrying amount) and write it down if necessary. The recoverability analysis of goodwill is performed systematically at the end of each year or whenever it is considered necessary to perform such an analysis. The recoverable amount is the higher of the estimated selling price of the asset less the related selling costs on the value in use of the asset. Value in use is taken to be the present value of the estimated future cash flows. In calculating the recoverable amount of goodwill, we used the value in use approach for all cases, preparing the projections of future pre-tax cash flows on the basis of the budgets most recently approved by our Board of Directors. These budgets include the best available estimates of the income and costs of the cash-generating units using industry projections, past experience and future expectations. These projections cover the coming four years, and the flows for future years are estimated by applying reasonable growth rates.

In light of the fact that analyzing the impairment of our recorded goodwill requires a combination of various assumptions and variables, it is very difficult to analyze the sensitivity of the projections to changes in any isolated variable on its own, since a change in one variable may have an effect on one or more of the other variables used.

The goodwill impairment analysis that we conducted as of December 31, 2011 did not suggest that any such impairment was likely in a future period.

The determination of the recoverable amount of a cash-generating unit under IFRS for impairment testing purposes involves the use of estimates by management. Methods used to determine these amounts include discounted cash flow methodologies and models based on quoted stock market prices. Key assumptions on which management has based its determination of fair value include ARPU (monthly average revenue per user), subscriber acquisition and retention costs, churn rates, capital expenditures and market share. These estimates can have a material impact on fair value and the amount of any goodwill write-down.

Accrued Post Retirement Liability

As of December 31, 2011, we recorded an accrued post retirement liability amounting to A990.4 million to cover our net unfunded obligations regarding pension supplements, post retirement healthcare benefits and salaries for pre-retired and suspended employees. We estimate our obligations regarding post retirement benefits based on actuarial valuations prepared annually by our actuaries, which use the projected unit credit method and consider certain demographic and financial assumptions. The key financial assumptions affecting post retirement benefit costs are based, in part, on actuarial valuations, including discount rates used to calculate the amount of the post retirement benefit obligations. The discount rate reflects the weighted average timing of the estimated defined benefit payments. The discount rate premium is determined based on European corporate bonds with a high quality rating. The assumptions concerning the expected return on plan assets are determined on a uniform basis, considering long-term historical returns, asset allocation and future estimates of long-term investment returns. In the event that further changes in assumptions are required with respect to discount rates and expected returns on invested assets, the future amounts of our post retirement benefit costs may be materially affected.

Provisions and Adjustments

Provisions are recorded when, at the end of the period, we have an obligation to a third party that is probable or certain to create an outflow of resources to the third party. This obligation may be legal, regulatory and contractual in nature. It may also be derived from our practice or from public

commitments having created a legitimate expectation for such third parties that we will assume certain responsibilities. To estimate the expenditure that we are likely to bear to settle the obligation, our management takes into consideration all of the available information at the closing date for our consolidated financial statements. If no reliable estimate of the amount of the obligation can be made, no provision is recorded; information is then presented in the notes to the financial statements.

Contingencies, representing obligations which are neither probable nor certain at the time of drawing up the financial statements, and obligations for which the cash outflow is not probable are not recorded. Information about them is presented in the notes to the consolidated financial statements.

Because of the inherent uncertainties in the foregoing evaluation process, actual losses may be different from the original estimated amount provisioned at the closing date.

The allowance for doubtful accounts receivable is stated at the estimated amount necessary to cover potential risks in the collection of overdue accounts receivable balances. A determination of the amount of allowances required is made after careful analysis of the evolution of accounts receivable balances, and, in specific cases, our analysis is also based on our knowledge of the financial situation of our customers. The required allowances may change in the future due to changes in economic conditions and our knowledge of specific issues. Future possible changes in recorded allowances would impact our results of operations in the period that such changes are recorded.

Assessment of the Fair Value of Financial Instruments

We choose an appropriate valuation method for financial instruments not traded in an active market based on our knowledge of the market and of the asset. In this process, we apply the valuation methods commonly used by market practitioners and use assumptions based on market rates.

Assessment of the Fair Value of Certain Assets Using the Revaluation Model

In 2008, we adopted the revaluation model for measuring the carrying value of certain classes of assets, namely the ducts infrastructure and real estate assets. In accordance with our policy, we revise the revalued amount at least once every three years and, accordingly, we performed another reevaluation during the year ended December 31, 2011. These revaluations were effective as of December 31, 2011 and resulted in a net reduction of tangible assets amounting to approximately A131.4 million, of which approximately A126.2 million was recognized directly in our consolidated statement of comprehensive income and A5.3 million was recognized in our consolidated income statement. In order to determine the revalued amount of those assets, we used the replacement cost method for the ducts infrastructure and the market value for real estate assets, which required the use of certain assumptions related to construction costs for the ducts infrastructure and the use of specific indicators for the real estate market. See Notes 3(c) and 37.4 to our audited consolidated financial statements for a more detailed explanation of the assumptions used.

Deferred Taxes

We recognize and settle income taxes based on the results of operations determined in accordance with local corporate legislation, taking into consideration the provisions of the applicable tax law, which are materially different from the amounts calculated for IFRS purposes. In accordance with IAS 12, Income Taxes, we recognize deferred tax assets and liabilities based on the differences between the carrying amounts and the taxable bases of the assets and liabilities. We regularly assess the recoverability of deferred tax assets and recognize an allowance for impairment losses when it is probable that these assets may not be realized, based on the history of taxable income, the projection of future taxable income, and the time estimated for the reversal of existing temporary differences. These calculations require the use of estimates and assumptions. The use of different estimates and

assumptions could result in the recognition of an allowance for impairment losses for the entire or a significant portion of the deferred tax assets.

Year Ended December 31, 2011 Compared to Year Ended December 31, 2010

Operating Revenues

Our operating revenues increased to A6,146.8 million in 2011 from A3,742.3 million in 2010, an increase of 64.3% reflecting the proportional consolidation of Oi and Contax as from April 1, 2011 (A2,768.0 million), which includes Dedic and GPTI as from July 1, 2011, following the completion of the exchange of our pre-existing interest in Dedic and GPTI for an additional interest in Contax. Excluding the effect of the proportional consolidation of Oi and Contax, our consolidated operating revenues would have decreased by 9.7% to A3,379.7 million in 2011 as a result of revenue declines in our Portuguese telecommunications business and the decrease in the contribution from Dedic/GPTI, which was fully consolidated until June 30, 2011 and then integrated in Contax. The decrease in revenues in our Portuguese telecommunications business was partially offset by revenue growth in our other international operations, namely MTC in Namibia and Timor Telecom. Contributions to our consolidated operating revenues from our Portuguese telecommunications businesses decreased by 7.5% (A233.5 million), and the contribution from other businesses increased by 35.8% (A228.9 million) for the reasons explained below.

Our revenues from our Portuguese telecommunications business in the year ended December 31, 2011 were negatively impacted by, among other things, (1) revenue declines in the Personal customer category, including the effects of lower mobile interconnection revenues, lower customer service revenues and lower sales, (2) lower revenues in the Enterprise customer category, which suffered due to the economic environment and (3) lower revenues from wholesale and other businesses, including the impact of a decline in the telephone directories business. These effects were partially offset by an increase in revenues from the Residential customer category, mainly related to Pay-TV and broadband revenues, which are driven by the success of the Meo double- and triple-play offers.

We present below the revenue information for each of our business segments, which, as described above, are as follows: (1) Telecommunications in Portugal (replacing the former operating segments ''Wireline in Portugal'' and ''Mobile in Portugal'') and (2) Telecommunications in Brazil—Oi (reflecting our proporational consolidation as from April 1, 2011 of TmarPart, which, in turn, fully consolidates Oi S.A. and its subsidiaries).

The revenue information for each segment in the tables below differs from the contribution to our consolidated revenues for each such segment in the table above because it is presented on a standalone basis and includes revenues from services rendered to other Portugal Telecom group companies.

Telecommunications in Portugal. The table below sets forth our operating revenues from our Portuguese telecommunications business in 2010 and 2011. As described in more detail in ''Item 4— Information on the Company—Our Businesses—Portuguese Operations,'' our Portuguese telecommunications business includes revenues from the residential, personal, enterprise and wholesale customer categories.

	2010	2011	% Change
	(EUR Millions)
Telecommunications in Portugal
Residential	647.0	682.3	5.4%
Personal	865.0	768.4	(11.2)%
Enterprise	1,079.6	982.1	(9.0)%
Wholesale, other and eliminations	532.8	459.2	(13.8)%
Total	3,124.5	2,892.0	(7.4)%

In the Residential customer category, operating revenues increased by 5.4% to A682.3 million in 2011 from A647.0 million in 2010. Our residential revenues benefitted from the commercial success of Meo, whose double-play and triple-play services (voice, data and Pay-TV) have grown and have partially mitigated the recent revenue loss trend in the Portuguese telecommunications business. As result of Meo's success, the weight of non-voice services in the Residential customer category stood at 58.1% in 2011, up by 7.2 percentage points compared to 2010.

In the Personal customer category, operating revenues decreased by 11.2% to A768.4 million in 2011 from A865.0 million in 2010, primarily due to (1) lower customer revenues (A54.9 million), which reflected the effects of challenging economic conditions that have made customers more price-sensitive, greater competitive pressures, increased popularity of ''tribal plans'' yielding lower revenues per user, as well as the negative effect of lower revenues from mobile broadband due to the higher popularity of fixed broadband, (2) lower interconnection revenues (A28.9 million), partially as a result of the negative impact of lower mobile termination rates and (3) lower equipment sales (A12.3 million). Notwithstanding the economic environment and significant growth in fixed broadband due to triple-play bundled offers, data revenues accounted for 30.9% of service revenues, an increase of 1.7 percentage points over 2010, as a result of the solid performance of ''internetnotelemovel'' (Internet on the cell phone) data packages, which continued to show strong growth, the commercial success of our ''e nunca mais acaba'' plan and increased penetration of smartphones, which partially offset the pressure on mobile broadband revenues.

Operating revenues from the Enterprise customer category decreased by 9.0% to A982.1 million in 2011 from Euro A1,079.6 million in 2010, negatively affected by the economic environment and consequent cost cutting efforts by companies, as well as the effect of one-off projects with the Portuguese government agencies that took place in 2010. Our strategy continued to focus on convergent offers and unlimited fixed-to-mobile voice and data solutions, integrated and vertical offers bundled with specific business software and flexible pricing solutions on a per workstation basis. Additionally, we continued to provide advanced one-stop-shop IT/IS solutions, focusing on business process outsourcing (BPO) and on the marketing of machine-to-machine solutions. These offers leverage on our investment in FTTH and cloud computing, which allow the offering of cloud-based services in partnership with software and hardware vendors.

Wholesale and other operating revenues, including intra-Portuguese businesses eliminations, decreased by 13.8% to A459.2 million in 2011 from A532.8 million in 2010, impacted by (1) lower revenues from directories (A20.4 million), (2) lower wholesale revenues (A24.7 million), mainly due to lower unbundled local loop (ULL) revenues and lower capacity sales and (3) lower revenues from public pay telephones (A4.0 million). The impact of regulation on wholesale revenues was approximately A3.0 million in 2011.

Telecommunications in Brazil—Oi. The table below sets forth our operating revenues from our Brazilian telecommunications business in 2011.

		2011
Telecommunications in Brazil—Oi
Services		2,297.5
Sales		12.0
Other		102.6
Total		2,412.1

Operating revenues from our Brazilian telecommunications business stood at A2,412.1 million, equivalent to R\$5,611.8 million. Oi's results are proportionally consolidated as from April 1, 2011, reflecting the 25.6% direct and indirect interest that we have in TmarPart, which, in turn, fully consolidates the Oi Companies, including Tele Norte Leste Participa¸coes (which merged into Oi S.A. in ˜ 2012), Telemar Norte Leste (which is now a subsidiary of Oi S.A.) and Brasil Telecom (which has been renamed Oi S.A.).

Other Businesses. Operating revenues from our other operations contributed A869.0 million to our consolidated operating revenues in 2011, an increase of 35.8% from A640.1 million in 2010. This performance was mainly due to (1) the impact of the proportional consolidation of Contax as from April 1, 2011 (A358.8 million), including Dedic/GPTI as from July 1, 2011 and (2) the increases of 10.6% and 7.0% at Timor Telecom and MTC, respectively. These effects were partially offset by a lower contribution from Dedic/GPTI, which was fully consolidated until June 30, 2011 and then integrated into Contax.

Costs, Expenses, Losses and Income

As explained in more detail below, our costs increased in 2011, primarily due to the impact of the proportional consolidation of Oi and Contax as from April 1, 2011. Adjusting for this effect, consolidated operating costs would have decreased reflecting (1) a reduction in costs in our Portuguese telecommunications business, primarily as a result of strict cost controls, a strong focus on the profitability of operations and lower direct costs resulting from the decrease in operating revenues and (2) a lower contribution from Dedic/GPTI as this business was fully consolidated until June 30, 2011 and then integrated into Contax. For more detail on these costs and expenses as they relate to each of our segments, see Note 7 to our audited consolidated financial statements.

Wages and Salaries. Wages and salaries, including employee benefits and social charges, increased by 60.2% to A1,020.5 million in 2011 from A637.1 million in 2010, primarily due to the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A505.4 million), including the Dedic/GPTI business as from July 1, 2011. Adjusting for this effect, wages and salaries would have decreased by 19.2% to A515.1 million in 2011, reflecting lower contributions from (1) Dedic/GPTI, as this business was fully consolidated until June 30, 2011 and then integrated into Contax and (2) the telecommunications business in Portugal, primarily reflecting lower variable and overtime compensation, higher efficiency levels in certain internal processes and lower personnel costs as a result of a restructuring plan implemented at the end of 2010.

Direct Costs. Direct costs increased by 84.9% to A1,012.3 million in 2011 from A547.6 million in 2010, primarily due to the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A521.3 million). Adjusting for this effect, direct costs would have decreased by 10.3% to A491.0 million in 2011, primarily due to lower contributions from the Portuguese telecommunications business as a result of a decrease in interconnection costs, mainly due to lower mobile termination rates, and lower costs related to the telephone directories business as a result of the decline in that business. These effects were partially offset by an increase in programming costs resulting from the continued growth in Pay-TV customers, despite a decline in programming costs per customer as Pay-TV is reaching critical mass.

Costs of Products Sold. Costs of products sold decreased by 5.6% to A169.9 million in 2011 from A179.9 million in 2010, reflecting primarily a lower contribution from the Portuguese telecommunications business (A37.9 million) in line with the decrease in sales and a rationalization of TMN's handset portfolio. This decrease more than offset the impact of the proportional consolidation of Oi and Contax as from April 1, 2011, amounting to A31.8 million.

Marketing and Publicity. Marketing and publicity costs increased by 61.7% to A131.1 million in 2011 from A81.1 million in 2010, reflecting primarily the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A48.5 million). Adjusting for this effect, marketing and publicity costs would have increased by 1.9% to A82.7 million in 2011, primarily explained by an increase at the Portuguese telecommunications business, reflecting the continued marketing of Meo and the new tariff plans aimed at the Personal customer category.

Supplies, External Services and Other Expenses. Supplies, external services and other expenses increased by 76.9% to A1,281.4 million in 2011 from A724.5 million in 2010. This increase is primarily explained by the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A597.4 million), partially offset by (1) a reduction in the Portuguese telecommunications business (A31.6 million), which reflected our continuing operational and cost discipline, and (2) the lower contribution from Dedic/GPTI, which was fully consolidated until June 30, 2011 and then integrated into Contax (A20.9 million).

Indirect Taxes. Indirect taxes increased by 3.0% to A187.5 million in 2011 from A45.4 million in 2010, reflecting primarily the impact of the proportional consolidation of Oi and Contax as from April 1, 2011, amounting to A146.2 million, which primarily includes spectrum fees (A52.6 million), indirect taxes related to the ''Fust'' fund (a fund to improve the general access to telecommunications services in Brazil) and the ''Funtel'' fund (the Brazilian National Telecommunications Fund), totaling A28.9 million, value-added tax expenses (A12.8 million), concession fees (A9.0 million) and other municipal, federal and state taxes in Brazil.

Provisions and Adjustments. Provisions and adjustments increased to A156.3 million in 2011 from A35.0 million in 2010, largely due to the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A135.0 million). Excluding this effect, provisions and adjustments would have decreased by 39.2% to A21.2 million, reflecting primarily a reduction in the Portuguese telecommunications business resulting from a lower level of doubtful receivables and lower provisions for legal actions.

Depreciation and Amortization. Depreciation and amortization costs increased by 74.7% to A1,325.6 million in 2011 from A758.6 million in 2010, reflecting primarily the impact of the proportional consolidation of Oi and Contax (A544.9 million), which includes the amortization of intangible assets recognized as a result of the purchase price allocation of the investments in Oi and Contax, amounting to A47.3 million in 2011. Adjusting for the proportional consolidation of Oi and Contax, depreciation and amortization cost would have increased by 2.9% to A780.6 million in 2011, reflecting a higher contribution from the Portuguese telecommunications business (A21.5 million) as a result of the FTTH rollout and Pay-TV growth, partially offset by the impact of a swap of TMN's 2G equipment for LTE (4G-enabled) equipment.

Post Retirement Benefits. Charges for post retirement benefits increased 53.2% to A58.5 million in 2011, compared to A38.2 million in 2010. The increase in this caption is primarily explained by a prior year service gain recorded in 2010, amounting to A31.2 million, resulting from changes introduced in the pension formula by Portuguese Law 3-B/2010 that led to a reduction in benefits granted to employees. Adjusting for this effect, post retirement benefit costs would have decreased by A10.9 million, primarily due to the positive impact of the transfer of regulatory unfunded pension obligations to the Portuguese State (A16.0 million), which was completed in December 2010, partially offset by the impact of the proportional consolidation of Oi as from April 1, 2011 (A4.5 million). This cost item does not include early termination costs related to our workforce reduction program, which are discussed under ''—Curtailment Costs'' below.

Curtailment Costs. Curtailment costs decreased to A36.4 million in 2011, compared to A145.5 million in 2010, primarily due to the reduction in employees undertaken by the end of 2010.

Other Costs. Other costs decreased to A32.6 million in 2011 from A141.2 million in 2010, primarily reflecting certain non-recurring items recorded in 2010, including (1) the recognition of provisions and adjustments in order to adjust certain receivables and inventories to their recoverable amounts and to reflect estimated losses with legal actions and (2) expenses incurred related to the Oi acquisition process.

Financial Income and Expenses

Net Interest Expenses. Net interest expenses increased by 60.6% to A297.1 million in 2011 from A185.0 million in 2010, primarily as a result of the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A175.2 million). Adjusting for this effect, net interest expenses would have decreased by A63.2 million to A121.9 million in 2011, mainly as a result of (1) a A51.4 million interest gain in the first quarter of 2011 on the cash deposits in Brazilian Reais that were used to pay for the strategic investments in Oi and Contax on March 28, 2011 and (2) the reduction in the average cost of debt of our Portuguese telecommunications busines, which was 3.3% in 2011, compared to 4.4% in 2010. These effects more than offset the impact of the increase in our average net debt, reflecting (1) the proporational consolidation of indebtedness of Oi and Contax beginning on April 1, 2011 (A3,727.6 million), (2) the dividends paid in June 2011 (A1,118.0 million) and (3) the debt related to the transfer of unfunded pension obligations to the Portuguese State completed in December 2010 (A1,021.7 million), which more than offset the impact of the first and second installments received from Telefonica in 2010 ( ´ A5,500 million) and the last installment received in October 2011 (A2,000 million) in connection with the Vivo transaction.

Net Foreign Currency Exchange Losses. We had net foreign currency losses of A18.1 million in 2011, compared to A6.8 million in 2010, primarily as a result of the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A15.8 million), the losses of which relate mainly to the impact of the depreciation of the Brazilian Real against the U.S. dollar on Oi's gross debt denominated in U.S. dollars that is not hedged through currency swaps. Adjusting for this effect, net foreign currency losses would have amounted to A2.3 million in 2011, as compared to A6.8 million in 2010 and are primarily explained by the impact of the depreciation of the U.S. dollar against the Euro on net assets denominated in U.S. dollars, primarily related to dividends receivable from Unitel.

Net Gains on Financial Assets and Other Investments. We recorded net gains on financial assets and other investments of A0.6 million in 2011, compared to A1.9 million in 2010. These gains primarily include the impact of the change in the fair value of certain free-standing interest rate derivatives and rents received from real estate, net of related depreciation costs.

Equity in Earnings of Affiliated Companies. Equity in earnings of affiliated companies increased to A209.2 million in 2011, compared to A141.7 million in 2010. In 2011, this caption includes a gain of A37.6 million related to the completion of the disposition of our investment in UOL for a total amount of A155.5 million, while in 2010, this caption includes one-time charges totalling A35.9 million to adjust the carrying values of certain of our investments to the corresponding estimated recoverable amounts (primarily in UOL in order to adjust its carrying value to the recoverable amount obtained upon the disposition of this investment, which was completed in January 2011). Adjusting for these effects and also for our share in UOL's earnings in 2010 (A14.3 million), equity accounting in earnings of affiliated companies would have amounted to A171.6 million in 2011 and A164.0 million in 2010, as a result of increased earnings of Unitel and CTM.

Net Other Financial Expenses. Net other financial expenses increased to A107.4 million in 2011, compared to A33.3 million in 2010, and include banking services, commissions, financial discounts and other financing costs. This increase primarily reflects (1) the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A52.5 million) and (2) certain financial taxes incurred in Brazil in connection with the transfer of funds for the investment in Oi (A13.6 million).

Income Taxes

Income taxes increased to A108.2 million in 2011, compared to A77.5 million in 2010, corresponding to effective tax rates of 20.4% and 23.3%, respectively. This increase is primarily explained by a gain of A59.0 million recorded in 2010 related to a corporate restructuring of our African assets held by our subsidiary Africatel, which resulted in lower taxable profits, and by the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A7.4 million). Adjusting for (1) the above-mentioned one-off tax gain recorded in 2010, (2) the impact of lower non-deductible interest expenses, (3) certain non-current losses recorded in 2010 and (4) adjustments to prior year income taxes, the effective tax rate would have been 24.4% in 2011, compared to 25.6% in 2010.

As from January 1, 2010, following a change in Portuguese tax legislation that occurred in the second quarter of 2010, we and our subsidiaries located in Portugal are subject to corporate income tax at a maximum aggregate tax rate of approximately 29.0%, corresponding to a base rate of 25%, which is increased (1) up to a maximum of 1.5% of taxable income through a municipal tax and (2) by a 2.5% state surcharge applicable to taxable income in excess of A2.0 million. Prior to this change, the 2.5% state surcharge did not exist and, consequently, the maximum aggregate income tax rate was approximately 26.5%. For the years 2012 and 2013, following a change in Portuguese tax legislation occurred in December 2011, we will be subject to corporate income tax at a base rate of 25%, increased (1) up to a maximum of 1.5% of taxable income through a municipal tax and (2) by a state surcharge levied at a rate of 3.0% on taxable income between A1.5 million and A10.0 million and at a rate 5.0% on taxable income in excess of A10.0 million, resulting in a maximum aggregate tax rate of approximately 31.5%.

Income from Continuing Operations (Before Discontinued Operations and Non-Controlling Interests)

Income from continued operations (before discontinued operations and non-controlling interests) increased by 66.1% to A422.9 million in 2011 from A254.6 million in 2010 for the reasons described above.

Income before financial results and taxes from our Portuguese telecommunications business increased to A498.4 million in 2011, compared to A415.1 million in 2010, primarily due to lower workforce reduction costs, supplies and external services, wages and salaries and other costs. These effects more than offset the impact of the reductions in operating revenues, net of related direct costs and costs of products sold, and higher depreciation and amortization and post retirement benefits costs.

Income before financial results and taxes from our Brazilian telecommunications business—Oi, which was proportionally consolidated as from April 1, 2011, amounted to A229.5 million.

Income from Discontinued Operations

Income from our discontinued operation, which related to Vivo, amounted to A5,565.4 million in 2010. We completed the sale of Vivo on September 27, 2010 and had no income from Vivo after that date.

Net Income Attributable to Non-Controlling Interests

Net income attributable to non-controlling interests amounted to A83.8 million in 2011 and was related primarily to our Africatel businesses (A64.6 million) and Oi (A11.7 million). In 2010, net income attributable to non-controlling interests amounted to A147.9 million and was related primarily to Vivo (A61.3 million) and our Africatel businesses (A76.1 million).

Net Income Attributable to Equity Holders of the Parent

For the reasons described above, our net income attributable to our equity holders decreased to A339.1 million in 2011 from A5,672.2 million in 2010.

Basic earnings per ordinary and ''A'' shares from total operations decreased to A0.39 in 2011 from A6.48 in 2010 on the basis of 864,161,921 and 875,872,500 average outstanding shares issued in 2011 and 2010 respectively.

Year Ended December 31, 2010 Compared to Year Ended December 31, 2009

Operating Revenues

Our operating revenues increased to A3,742.3 million in 2010 from A3,733.4 million in 2009, an increase of 0.2% due to our strong performance in our international operations, namely MTC in Namibia, Timor Telecom and Dedic/GPTI, partially offset by lower revenues from our Portuguese telecommunications business. Contributions to consolidated operating revenues from our Portuguese telecommunications business decreased by 4.8% (A154.8 million), and the contribution from other businesses increased by 34.3% (A163.6 million) for the reasons explained below.

Telecommunications in Portugal. The table below sets forth the operating revenues from our Portuguese telecommunication business in 2009 and 2010. As explained above under ''—Overview— Change in Segment Reporting,'' we are not able to provide a breakdown of revenues by customer category for the year ended December 31, 2009, although we provide qualitative information on those customer categories below.

	2009	2010	% Change
	(EUR Millions)
Telecommunications in Portugal
Services	3,059.3	2,933.6	(4.1)%
Sales	178.9	149.4	(16.5)%
Other	34.9	41.4	18.7%
Total	3,273.1	3,124.5	(4.5)%

Revenues from our Portuguese telecommunications business decreased to A3,124.5 million in 2010 from A3,273.1 million in 2009, a reduction of 4.5% primarily explained by (1) a revenue decline in the Personal customer category, mainly as a result of the negative impact of lower mobile termination rates, lower customer service revenues that reflect increased competitiveness in certain market categories (especially in the youth category) and challenging economic conditions in Portugal, and lower sales; (2) lower revenues in the Enterprise customer category, which suffered from the economic environment and (3) lower revenues from our wholesale and other businesses, including the impact from the decline in the telephone directories business. These effects were partially offset by an increase in revenues in the Residential customer category, mainly related to Pay-TV and broadband revenues, which were driven by the success of the double and triple-play offers of Meo.

Other Businesses. Operating revenues from our other businesses contributed A640.1 million to our consolidated operating revenues in 2010, an increase of 34.3% from A476.5 million in 2009. This performance was mainly due to (1) the increases of 30.3% and 20.1% at Timor Telecom and MTC, respectively, (2) the improving trends of our Brazilian BPO business, Dedic, and (3) the consolidation of GPTI, an IT/IS company acquired by Dedic as from March 1, 2010. We fully consolidated the revenues of Dedic during the years ended December 31, 2009 and 2010, and we fully consolidated the revenues of GPTI from March 1, 2010 through December 31, 2010.

Costs, Expenses, Losses and Income

As explained in more detail below, our costs increased in 2010 due to, among other factors, increases in net curtailment and settlement costs, wages and salaries, depreciation and amortization and other costs, which were partially offset by reductions in post retirement benefits costs and costs of

products sold. For more detail on these costs and expenses as they relate to each of our segments, see Note 7 to our audited consolidated financial statements for the year ended December 31, 2011.

Wages and Salaries. Wages and salaries, including employee benefits and social charges, increased by 16.5% to A637.1 million in 2010 from A546.7 million in 2009, primarily due to higher contributions from (1) Dedic, arising from investments made in 2010 to expand this business and also the impact of the appreciation of the Brazilian Real (A23.2 million) and (2) GPTI, which was consolidated as from March 1, 2010 (A34.2 million).

Direct Costs. Direct costs increased by 4.8% to A547.6 million in 2010 from A522.4 million in 2009, primarily due to an increase in our Portuguese telecommunications business (A20.5 million), reflecting the growth in programming costs resulting from the continued growth in Pay-TV customers, strengthened content offerings and a higher uptake of premium and VOD services, partially offset by a reduction in interconnection costs, mainly due to lower mobile termination rates, and lower costs related to the telephone directories business as a result of the decline in that business.

Costs of Products Sold. Costs of products sold decreased by 13.2% to A179.9 million in 2010 from A207.3 million in 2009, primarily reflecting a reduction at the Portuguese telecommunications business (A45.5 million) in line with the decrease in sales and our continued focus on increasing the number of exclusive handsets and reducing the breadth of TMN's handset portfolio.

Marketing and Publicity. Marketing and publicity costs increased by 3.2% to A81.1 million in 2010 from A78.6 million in 2009, primarily reflecting a higher contribution from MTC and from costs of marketing in the Residential customer category, especially the marketing of Pay-TV and triple-play offers. These effects were partially offset by lower costs related to the Personal customer category in line with the reduction in operating revenues.

Supplies, External Services and Other Expenses. Supplies, external services and other expenses decreased by 1.2% to A724.5 million in 2010 from A733.3 million in 2009. This decrease is primarily explained by a lower contribution from the Portuguese telecommunications business, mainly due to lower maintenance and repair costs resulting from a more integrated and efficient management of our fixed and mobile networks, and lower external supplies, which reflect our continuing operational and cost discipline. These effects were partially offset by (1) the impact of the consolidation of GPTI as from March 1, 2010 (A15.9 million) and (2) an increase in costs from our contact center operations in Brazil, primarily related to rental costs in connection with the construction of new sites completed in 2010 and also related to the appreciation of the Brazilian Real.

Indirect Taxes. Indirect taxes decreased by 21.4% to A45.4 million in 2010 from A57.8 million in 2009, reflecting primarily a reduction in spectrum fees, related to the Personal customer category, and a reduction in certain foreign operations.

Provisions and Adjustments. Provisions and adjustments increased by 14.6% to A35.0 million in 2010 from A30.5 million in 2009, largely due to an increase in the Portuguese telecommunications business (A5.5 million), reflecting primarily a change in the criteria for the calculation of provisions for receivables, which more than offset the effects of the declining trend in revenues.

Depreciation and Amortization. Depreciation and amortization costs increased by 5.8% to A758.6 million in 2010 from A716.9 million in 2009, primarily reflecting a higher contribution from the Portuguese telecommunications business (A32.6 million) as a result of the investments in the continued rollout of our Pay-TV service and the accelerated depreciation of certain GSM network equipment, following the decision to roll-out a swap of 2G network equipment for new LTE (4G-enabled) equipment.

Post Retirement Benefits. We recorded a A38.2 million charge for post retirement benefits in 2010, compared to A89.6 million in 2009. The decrease in this caption is primarily explained by a prior year service gain recorded in 2010, amounting to A31.2 million, resulting from changes introduced in the pension formula by Portuguese Law 3-B/2010 related to a reduction in benefits granted to employees. Adjusting for this effect, post retirement benefit costs would have decreased by A20.2 million, primarily due to (1) the reduction of A104.6 million in post retirement liabilities that occurred during 2009, (2) the increase in fair value of plan assets occurred in 2009, from A2,131.6 million to A2,369.5 million as a result of the performance of the plan assets and contributions to the pension funds and (3) a reduction of the discount rate from 5.75% to 5.50%. This cost item does not include early termination costs related to our workforce reduction program, which are discussed under ''—Curtailment and Settlement Costs'' below.

Curtailment and Settlement Costs. Curtailment costs increased to A145.5 million in 2010, compared to A14.8 million in 2009, primarily due to reengineering of processes and reorganization of our company along customer categories (i.e. residential, personal, enterprise (corporate and SMEs/SoHos) and wholesale).

Other Costs. Other costs increased to A141.2 million in 2010 from A45.6 million in 2009, primarily as a result of (1) the recognition of provisions and adjustments in order to reflect the recoverable amount of certain assets and estimated losses with legal actions and (2) expenses incurred related to the Oi acquisition.

Financial Income and Expenses

Net Interest Expenses. Net interest expenses decreased by 18.7% to A185.0 million in 2010 from A227.5 million in 2009, primarily as a result of a decrease in average net debt (debt minus cash and cash equivalents) following the first installment received from Telefonica in September 2010 ´ (A4,500 million) for the disposal of our interest in Vivo. This effect was slightly offset by an increase in the average cost of debt, which was 4.4% in 2010 and 4.3% in 2009.

Net Foreign Currency Exchange Losses. We had net foreign currency losses of A6.8 million in 2010, compared to A0.2 million in 2009, primarily as a result of the impact of the depreciation of the U.S. dollar against the Euro during the second half of 2010 on dividends paid by Unitel in June 2010.

Net Gains on Financial Assets and Other Investments. We recorded net gains on financial assets and other investments of A1.9 million in 2010, compared to A8.1 million in 2009. Gains recorded in 2009 are primarily explained by a gain of A5.7 million related to the impact on a free-standing cross currency derivative of the appreciation of the U.S. dollar against the Euro until April 2009, when this financial instrument was settled. This caption also includes the impact of the change in fair value of interest rate derivatives.

Equity in Earnings of Affiliated Companies. Equity in earnings of affiliated companies decreased to A141.7 million in 2010, compared to A456.0 million in 2009, with the decline explained mainly by (1) one-time charges in 2010 totaling A35.9 million to adjust the carrying values of certain of our investments to the corresponding estimated recoverable amounts, primarily in UOL in order to adjust its carrying value to the recoverable amount obtained upon the disposal of this investment, which was completed in January 2011, (2) the capital gain, amounting to A267.0 million, obtained with the sale of Medi T ´ el ´ ecom in the fourth quarter of 2009 and our share in the earnings of this company until its sale ´ and (3) the impact of the devaluation of the Kwanza against the Euro. Adjusting for these effects, equity in earnings of affiliates would have amounted to A192.1 million in 2010 and A178.4 million in 2009, as a result of increased earnings of Unitel, in local currency, and UOL. On December 29, 2010, we reached an agreement for the sale of our interest in UOL (28.78% of UOL's share capital) for a consideration of R\$356 million. The transaction closed on January 27, 2011.

Net Other Financial Expenses. Net other financial expenses decreased to A33.3 million in 2010, compared to A35.7 million in 2009, and include banking services expenses, commissions, financial discounts and other financing costs.

Income Taxes

Income taxes amounted to A77.5 million in 2010, compared to A185.9 million in 2009, corresponding to effective tax rates of 23.3% and 20.8%, respectively. In 2010, this caption includes a gain of A59.0 million related to a corporate restructuring of our African businesses held by our subsidiary Africatel, which resulted in lower taxable profits. Adjusting for this effect and for the non-taxable gain related to the sale of Medi T ´ el ´ ecom ( ´ A267.0 million recorded in the fourth quarter of 2009), one-time losses recognized in 2010 without a tax impact and higher interest expenses that were non-deductible for tax purposes, income taxes would have amounted to A136.6 million in 2010, corresponding to an effective tax rate of 28.8%, compared to 26.6% in 2009. This increase in the effective tax rate is primarily explained by an increase in the statutory tax rate in Portugal.

Income from Continuing Operations (Before Discontinued Operations and Non-Controlling Interests)

Income from continuing operations (before discontinued operations and non-controlling interests) decreased by 64.0% to A254.6 million in 2010 from A706.7 million in 2009 for the reasons described above.

Income before financial results and taxes from our Portuguese telecommunications business decreased to A415.1 million in 2010 from A674.6 million in 2009, primarily due to the reduction in operating revenues, net of the related direct costs and costs of products sold and higher curtailment, depreciation and amortization and other costs. These effects were partially offset by lower post retirements benefits costs and lower costs of suppliers and external services.

Income from Discontinued Operations

Income from our discontinued operation, which related to Vivo, amounted to A5,565.4 million in 2010, compared to A82.5 million in 2009. The income recorded in 2010 included a gain of A5,423.0, net of related expenses, obtained from the sale of our investment in Vivo, which was completed on September 27, 2010. We received A4.5 billion from Tel ´ efonica on September 27, 2010 and a further ´ A1.0 billion on December 30, 2010. Excluding this effect and positive foreign currency translation adjustments transferred to net income (A31.9 million in 2010 and A21.6 million in 2009) following a share capital reduction at Brasilcel N.V., the joint venture vehicle that held our interest in Vivo, this caption reflects the net income of Vivo, which increased primarily due to an improvement in financial expenses and the appreciation of the Brazilian Real.

Net Income Attributable to Non-Controlling Interests

Net income attributable to non-controlling interests in 2010 amounted to A147.9 million and was related primarily to Africatel businesses (A76.1 million) and the Vivo (A61.3 million). In 2009, net income attributable to non-controlling interests amounted to A104.5 million and was related primarily to Africatel businesses (A54.2 million) and the Vivo (A42.6 million).

Net Income Attributable to Equity Holders of the Parent

For the reasons described above, our net income attributable to equity holders of Portugal Telecom increased to A5,672.2 million in 2010 from A684.7 million in 2009.

Basic earnings per ordinary and A shares from total operations increased to A6.48 in 2010 from A0.78 in 2009 on the basis of 875,872,500 average outstanding shares issued in 2010 and 2009.

Liquidity and Capital Resources

Overview

Our principal capital requirements relate to:

• funding our operations;
• capital expenditures on our network infrastructure, information systems and other investments, as well as acquisitions of interests in other telecommunications companies (see ''—Capital Investment and Research and Development'' and ''—Contractual Obligations and Off-Balance Sheet Arrangements'' below);
• repayments and refinancing of our indebtedness (see ''—Indebtedness'' below);
• shareholder remuneration in the form of dividend payments; and
• funding of post retirement benefits (see ''—Post Retirement Benefits'' below).

Our principal sources of funding for these capital requirements are cash generated from our operations and equity and debt financing. Our cash and cash equivalents and short-term investments increased to A5,668.1 million as of December 31, 2011, compared to A5,106.5 million as of December 31, 2010. We believe that our cash balances, together with the cash that we expect to generate from our operations and available liquidity under our credit facilities and lines of credit, are currently sufficient to meet our present funding needs.

In September 2010, we concluded the sale of our 50% investment in Brasilcel N.V. to Telefonica ´ for A7.5 billion, of which we received A5.5 billion in 2010 and A2.0 billion in October 2011. In December 2010, we paid to our shareholders an extraordinary and anticipated dividend of A1.0 per share, totaling A875.9 million.

In December 2010, we reached an agreement with the Portuguese government for the transfer of certain regulated pension obligations and related funds and agreed to pay the unfunded obligation amounting to A1,022 million up to December 2012. We paid A100 million in December 2010 and A467 million in 2011, and we expect to pay the remaining A454 million in 2012. See ''—Post Retirement Benefits.''

On March 28, 2011, we completed the acquisition of an economic interest of 25.3% in Oi and 42.0% in CTX, respectively, for a total consideration of R\$8.4 billion (A3.7 billion). In June 2011, we paid to our shareholders a dividend of A1.3 per share, totaling A1,118.0 million, including an ordinary dividend of A0.65 per share relating to the year 2010 and an extraordinary dividend of A0.65 per share (relating to the total exceptional dividend of A1.65 proposed following the disposal of our investment in Brasilcel, of which A1 per share had already been paid in December 2010).

Our cash balances as of December 31, 2010 were materially impacted by these non-recurring transactions.

Cash Flows

The table below sets forth a breakdown of our cash flows from continuing operations for the years ended December 31, 2009, 2010 and 2011. For a discussion of the cash flow of our Vivo discontinued

operations, see Note 21 to our audited consolidated financial statements for the year ended December 31, 2011.

	2009	2010	2011

Cash Flow from Operating Activities

Cash flows from operating activities include collections from clients, payments to suppliers, payments to personnel, payments relating to income and indirect taxes and payments related to post retirement benefits activities. Our cash flows from operating activities result primarily from operations conducted by our subsidiaries and jointly controlled entities and not by Portugal Telecom. None of our subsidiaries and jointly controlled entities is subject to economic or legal restrictions on transferring funds to us in the form of cash dividends, loans or advances that would materially affect our ability to meet our cash obligations.

Net cash flow from operating activities related to continuing operations increased by 96.4% to A1,775.2 million in 2011 from A903.8 million in 2010. This increase reflects primarily the impact of the proportional consolidation of Oi and Contax as from April 1, 2011, totaling A585.7 million. Adjusting for this effect, net cash flow from operating activities would have increased by A285.8 million to A1,189.6 million in 2011, reflecting (1) lower payments to suppliers (A373.2 million), as a result of a one-off reduction in the payment cycle to certain suppliers undertaken at the end of 2010 using a portion of the cash we received from the Vivo transaction, (2) a reduction in payments to employees (A109.1 million), primarily due to a lower contribution from Dedic/GPTI business, which was fully consolidated until June 30, 2011 and then integrated into Contax, and (3) lower payments related to post retirement benefits (A37.4 million). These effects were partially offset by (1) lower collections from customers (A195.9 million), which reflect the decline in revenues from the Portuguese telecommunications business and the lower contribution from the Dedic/GPTI business and (2) an increase in payments relating to income taxes (A38.7 million).

Net cash flow from operating activities related to continuing operations decreased by 16.4% to A903.8 million in 2010 from A1,081.2 million in 2009. This decrease was primarily due to a A202.5 million reduction in collections from customers and an increase of A88.3 million in payments to employees, mainly related to our Dedic contact center operations in Brazil. These effects were partially offset mainly by a decrease of A74.1 million in payments relating to income taxes, primarily in our Portuguese telecommunications business, following the reduction in our taxable earnings.

Cash Flow from (Used in) Investing Activities

Cash flows from investing activities include proceeds from disposals of investments in associated companies and property, plant and equipment, as well as interest and related income on investments. Cash flows used in investing activities primarily include investments in short-term financial applications, capital expenditures for telecommunications equipment and investments in other companies.

Net cash used in investing activities related to continuing operations increased to A3,009.2 million in 2011 from A1,301.2 million in 2010. This increase primarily reflects the impact of the proportional consolidation of Oi and Contax (A2,223.7 million, adjusted for their cash and cash equivalents as of March 31, 2011) and the acquisition by Contax of Allus Global BPO Center (A41.9 million, adjusted for Allus's cash and cash equivalents as of the acquisition date). These effects were partially offset by (1) the proceeds obtained in 2011 from the disposition of our investment in UOL (A155.5 million), (2) the increase in cash receipts from interest and related income (A254.0 million), primarily due to the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A70.7 million) and interest income received in the first quarter of 2011 on the cash deposits in Brazilian Reais that were used to pay for the strategic investments in Oi and Contax and (3) higher dividends received (A93.1 million), mainly related to our interest in Unitel.

Net cash used in investing activities related to continuing operations amounted to A1,301.2 million in 2010, compared to A296.8 million in 2009. The change in this caption was primarily due to (1) an increase of A333.4 million in net cash payments from short-term financial applications, following the disposition of the 50% interest in Vivo, (2) a A397.5 million decrease in cash receipts from dispositions of investments, primarily related to the disposition of Medi T ´ el ´ ecom in 2009 (which had a ´ A400.0 million effect in that year) and (3) a A269.3 million increase in cash payments for the acquisition of tangible and intangible assets.

Cash Flows from (Used In) Financing Activities

Cash flows used in financing activities related to continuing operations include repayments of debt, payments of interest on debt and payments of dividends to shareholders. Cash flows from financing activities primarily consist of borrowings.

Net cash used in financing activities decreased to A540.3 million in 2011 from A1,571.2 million in 2010, mainly due to (1) an increase in net cash receipts from loans obtained (A1,255.9 million), primarily including the A600.0 million Eurobond issued in January 2011 and the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A248.9 million), and (2) a decrease in dividends paid (A245.9 million), primarily reflecting the reduction in dividends paid to our shareholders (A261.5 million). These effects were partially offset by (1) higher cash payments resulting from interest and related expenses (A335.1 million), primarily including the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A256.1 million) and (2) the acquisition of treasury shares in 2011 (A86.8 million), reflecting the proportional consolidation of our interest in purchases of Portugal Telecom shares by Oi, as explained below.

Cash receipts from loans obtained, net of cash payments from loans repaid, primarily relate to commercial paper and other bank loans and amounted to A1,455.2 million in 2011. As described in more detail in Note 38 to our audited consolidated financial statements for the year ended December 31, 2011, net cash receipts from loans obtained in 2011 primarily included (1) the A600.0 million Eurobond issued by PT Finance in February 2011, (2) an increase of A466.0 million in the outstanding amount under commercial paper programs, (3) an amount of A750.0 million drawn under the new credit facility secured in March 2011 and (4) bonds issued by Brasil Telecom and Tele Norte Leste Participa¸coes totaling ˜ A710.3 million. These effects were partially offset by (1) repayments by Tele Norte Leste Participa¸coes of certain financings that were outstanding as of March 31, 2011 ˜ (A385.4 million), (2) the payment of A450.0 million to the Portuguese State in December 2011 related to the transfer of unfunded pension obligations completed in December 2010 and (3) a payment regarding the equity swap contracts on our own shares amounting to A84.3 million.

In 2010, cash receipts from loans obtained, net of cash payments from loans repaid, amounted to A199.3 million, primarily due to two loans obtained from the EIB totaling A200.0 million.

In 2009, cash receipts from loans obtained included (1) Eurobonds issued by PT Finance totaling A2,050.0 million and (2) floating rate notes issued by PT Finance in July 2009 amounting to A250.0 million. Cash payments from loans repaid in 2009 included the repayments of (1) the Eurobonds issued by PT Finance in 1999 (A880.0 million), (2) commercial paper outstanding as of December 31, 2008 (A648.6 million) and (3) floating rate notes issued by PT Finance in December 2008 (A200.0 million).

In 2011, 2010 and 2009, dividends paid amounted to A1,206.1 million, A1,452.0 million and A535.5 million, respectively. In December 2011, as approved by our Board of Directors, we attributed to our shareholders an anticipated dividend over 2011 profits of A0.215 per share, totaling A184.8 million, which was paid on January 4, 2012.

In 2011, under the strategic partnership entered into between Portugal Telecom and Oi, Telemar Norte Leste acquired 64,557,566 of our own shares, representing 7.2% of our share capital, including A61.5 million related to shares acquired before the end of March 2011 and A86.8 million related to shares acquired in the second quarter of 2011. The A86.8 million amount was proportionally consolidated in our consolidated statement of cash flows.

Indebtedness

Our total consolidated indebtedness increased by 70.4% to A12,281.0 million at the end of 2011, compared to A7,206.3 million as of December 31, 2010, reflecting (1) net cash receipts from loans obtained (A1,255.9 million), primarily including the issuances and repayments of loans obtained described above under ''—Cash Flows—Cash Flows from (Used In) Financing Activities'' and (2) the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A3,748.6 million).

Our cash and cash equivalents increased to A4,930.0 million as of December 31, 2011 from A4,764.7 million as of December 31, 2010, primarily explained by (1) the third and last installment received from Telefonica in October 2011 for our disposition of the 50% interest in Vivo and (2) net ´ cash receipts from operating activities in 2011 (A1,775.2 million), which more than offset (a) net cash payments from investing activities in 2011 related to continuing operations (A3,009.2 million), primarily reflecting the acquisition of our investments in Oi and Contax and (b) the net cash payments from financing activities in 2011 (A540.3 million), as explained above.

Our short-term investments increased to A738.1 million as of December 31, 2011 from A341.8 million as of December 31, 2010, reflecting the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (A192.2 million) and payments, net of cash receipts, resulting from short-term financial applications, amounting to A204.2 million in 2011.

Of the total indebtedness outstanding as of December 31, 2011, 73.2% was medium and long-term debt, compared to 86.8% as of December 31, 2010.

The composition of our consolidated indebtedness as of December 31, 2009, 2010 and 2011 was as follows:

	As of December 31,
Debt	2009		2010		2011

Maturity

Of the total indebtedness outstanding as of December 31, 2011, A3,291.6 million is due before the end of December 2012. The remaining A8,989.4 million is medium and long-term debt. As of December 31, 2011, the average maturity of our total indebtedness, net of cash and cash equivalents and short-term investments, was 5.9 years.

Interest Rates

As of December 31, 2011, 61.1% of our total indebtedness was at fixed rates, a reduction from 91.0% as of December 31, 2010, which is primarily explained by the impact of the proportional consolidation of Oi and Contax as from April 1, 2011 (approximately 80% of which debt bears interest at variable rates). Excluding the proportional consolidation of Oi and Contax as of December 31, 2011, 79.2% of our total indebtedness was at fixed rates, primarily as a result of the fixed-rate bonds issued by PT Finance in 2005, 2007 and 2009.

Credit Ratings

Our credit ratings are currently as follows:

Rating Agency	Credit Rating	Outlook	Last Change
Moody's	Ba2	Negative	April 13, 2012
Standard & Poor's .	BB+	Negative	January 20, 2012

Debt Instruments and Repayment and Refinancing of Indebtedness

Set forth below is a brief description of certain of our debt instruments.

• Bonds. We have established a Euro Medium Term Note program (''EMTN'') providing for the issuance of bonds. The EMTN allows for bonds to be issued in a range of currencies and forms, including fixed and floating rates, zero coupon and index linked. As of December 31, 2011, the total size of this program was A7.5 billion. As of December 31, 2011, we had outstanding bonds of A4,936.0 million.

• Portuguese Commercial Paper Programs. We have entered into several domestic commercial paper programs, under which we had issued a total amount of A554.0 million as of December 31, 2011, which matured in January 2012. Since December 31, 2011, we have rolled over and/or repaid these amounts. In addition, under these programs, we had available an underwritten amount of A200 million as of December 31, 2011.

  • Financing agreements entered into with the Brazilian national development bank (Banco Nacional de Desenvolvimento Economico e Social ˆ , or ''BNDES'') by several of the Oi Companies for the purpose of financing investments between 2009 and 2011, totaling R\$4,403 million. Interest is payable monthly from January 2012 to May 2018, and principal amortizes monthly until final maturity in December 2018. The outstanding amount due as of December 31, 2011 was R\$3,054 million, and Portugal Telecom's proportionally consolidated portion was A324 million as of December 31, 2011.
  • A loan of R\$4,300 million obtained in May 2008 by Telemar from Banco do Brasil for the purpose of acquiring an equity interest in Brasil Telecom, with interest being payable semi-annually. The remaining principal amount is payable in four annual installments beginning on May 2015. The outstanding amount due as of December 31, 2011 was R\$3,071 million, and Portugal Telecom's proportionally consolidated portion was A326 million as of December 31, 2011.
  • A credit facility entered into by Telemar in November 2006 with BNDES to finance the expansion and technological upgrading of its fixed line network. Interest and principal are payable monthly through June 2014.

As of December 31, 2011, we had equity swap contracts over 20,640,000 treasury shares, which were recognized as an effective acquisition of treasury shares, requiring us to recognize a corresponding financial liability for the related acquisition cost in the amount of A178.1 million. In December 2011, we settled an amount of A84.3 million of the outstanding amount previously due and, consequently, the liability as of December 31, 2011 was reduced to A93.8 million.
• Financing Relating to the Transfer of Unfunded Pension Obligations. Following the transfer of certain unfunded pension obligations to the Portuguese State for a total amount of A1,021.7 million, we paid A100.0 million in December 2010, A17.4 million in January 2011 and A450.0 million in December 2011. The remaining A454.3 million must be paid no later than December 20, 2012 and bears interest at an annual rate of 3.25%.

Covenants

Our debt instruments contain certain covenants, as well as customary default and cross-acceleration provisions. As of December 31, 2011, the main covenants are as follows:

• Change in Control. The exchangeable bonds, the credit lines amounting to A1,640.0 million, the loans obtained from EIB totaling A594.0 million as of December 31, 2011, the export credit facility totaling A180.0 million and a A50 million term loan provide for penalties in the case of any change in control of Portugal Telecom. According to the terms and conditions of these debt instruments, a change of control would occur if any person or group of persons acting in concert acquires or controls more than 50% of voting rights, whether obtained by ownership of share capital, the holding of voting rights or pursuant to the terms of a shareholders' agreement. In certain cases, gaining the power to appoint or remove all, or the majority, of the directors or other equivalent officers of the company or to give directions with respect to the operating and financial policies of the company with which the directors or equivalent officers of the company are obliged to comply are also considered a change of control.
• Change of Control with Ratings Trigger. The Eurobonds amounting to A1,000 million and A750 million issued in 2009 and the A600 million Eurobonds issued in 2011 provide for penalties in the case of any change of control of Portugal Telecom, as described above, if simultaneously a rating downgrade to sub-investment grade occurs (in case the securities are investment grade securities) or a rating downgrade occurs (in case the securities are sub-investment grade securities) during the Change of Control Period, as defined under the terms and conditions of these notes.
• Credit Ratings. Certain loan agreements with the EIB, totaling A129 million as of December 31, 2011, state that we may be asked to present a guarantee acceptable to the EIB if, at any time, the long-term credit rating assigned by the rating agencies to Portugal Telecom is reduced from the rating assigned by the time the clause was included (BBB- by S&P, Baa2 by Moody's and BBB by Fitch). As of December 31, 2011, the repayment schedule of the A129 million loans is as follows: A46 million in 2012, A46 million in 2013 and A36 million in 2014. Our current credit ratings are BB+ by S&P, Ba2 by Moody's and BBB by Fitch. Consequently, as a result of our recent rating downgrades and considering this credit rating covenant, we and the EIB have agreed to (1) increase the spread of the loans mentioned above and (2) open a cash deposit amounting to a portion of the amount due under the loan agreements that include the credit rating covenant, pledged in favor of the EIB, which will be reduced as the loans are repaid. In addition, the spread paid under the A1,200 million revolving credit facility depends on whether the credit rating is or is not higher than BBB- (as assigned by S&P) and Baa3 (as assigned by Moody's), and the margin paid under the A200 million underwritten portion of our commercial paper program also depends on the credit ratings assigned by S&P and Moody's. See ''—Credit Ratings'' above.
• Control and Limitations on Disposals of Subsidiaries. As of December 31, 2011, certain credit facilities and commercial paper programs in the aggregate amount of A1,445 million provide that we must, directly or indirectly, maintain majority ownership and control of each material subsidiary. Material subsidiaries are those companies whose total assets are equal to or exceed 10% of total consolidated assets or whose total revenues are also equal or exceed 10% of total consolidated revenues.
• Dispositions of Assets. Credit facilities totaling A150 million and EIB loans totaling A594 million as of December 31, 2011 include certain restrictions regarding the disposition of assets by Portugal Telecom.
• Financial Ratios. Certain credit facilities and loans totaling A1,745 million require that the ratio of Consolidated Net Debt to EBITDA may not exceed certain values, which vary depending on the loan agreements. In addition, the pricing conditions applicable to certain facilities in the total amount of A215 million may be changed depending on the ratio of Consolidated Net Debt to EBITDA. Net debt is defined as total short, medium and long-term debt minus cash and cash equivalents and short-term investments. EBITDA is defined as income before financial results and taxes plus depreciation and amortization expenses, post retirement benefits costs, curtailment costs, net losses on disposals of fixed assets and net other costs. The ratio of net debt to EBITDA amounted to 2.7 in 2011, adjusted for the proportional consolidation of Oi and Contax in the first quarter and 1.4 and 2.3 in 2010 and 2009, respectively.
• Negative Pledge. The Euro Medium Term Notes, the exchangeable bonds, the revolving credit facilities, the export credit facility, the commercial paper programs and the A50 million term loan are subject to negative pledge clauses, which restrict the granting of security interests in the assets of companies included in the consolidation.

The penalties applicable in the event of default in any of these covenants are generally the early payment of the loans obtained or the termination of available credit facilities. We believe we are in full compliance with the covenants described above, after giving effect to our agreement with the EIB described under ''—Credit Ratings.''

We discuss our exposure to interest rate and exchange rate risk, as well as our use of derivative instruments, in ''Item 11—Quantitative and Qualitative Disclosures About Market Risk.''

Post Retirement Benefits

On December 2, 2010, we reached an agreement with the Portuguese State for the transfer to Caixa Geral de Aposenta¸coes, the Portuguese institution responsible for managing post retirement ˜ benefits for civil servants, of the pension liabilities that were guaranteed by PT Comunica¸coes relating ˜ to a portion of its active and former employees, as well as the pension fund assets associated with those liabilities. The transfer included the Plano de Pensoes do Pessoal da Portugal Telecom/CGA, ˜ the Plano de Pensoes Regulamentares da Companhia Portuguesa R ˜ adio Marconi ´ and the liabilities associated with the survival benefit in the Plano de Pensoes Marconi ˜ (collectively, the ''Regulated Pension Plans'').

The present value of the liabilities associated with the Regulated Pension Plans, as of the date of transfer, was A2,803.8 million, as determined by an independent actuary. The market value of the pension fund assets transferred, as of the date of the transfer, was A1,782.1 million. Accordingly, the unfunded transferred liabilities amounted to A1,021.7 million, of which we paid A100 million in December 2010 and A467 million in 2011, and we must pay the remaining A454 million by December 2012.

Following the transfer of certain pension plans to the Portuguese State, we are now responsible for a fixed monthly contribution to Social Security and the Caixa Geral de Aposenta¸coes in order to fund ˜ future benefits for the active beneficiaries included in these plans.

In addition, following our strategic investment in Oi, we proportionally consolidated its net post retirement benefit obligations, amounting to A61.7 million as of December 31, 2011, which relate to several plans with different characteristics, including defined contribution plans and defined benefits plans. Most of these plans are closed to new participants. Oi has several plans that are currently in a surplus position that is not recorded as an asset because is not possible to obtain reimbursements of that surplus.

The following table shows the amount of our liabilities for post retirement benefits recorded on our statements of financial position as of December 31, 2009, 2010 and 2011:

	As of December 31,
	2009	2010	2011
	(EUR Millions)
Gross projected pension benefit obligations	2,710.2	129.9	121.6
Minus: Pension fund assets at fair value	(1,954.8)	(109.3)	(98.5)
Prior years' service gains(1)	9.4	5.2	4.5
Accrued pension liabilities	764.9	25.8	27.6
Gross projected healthcare benefit obligations	335.3	342.5	352.6
Minus: Healthcare fund assets at fair value	(414.8)	(338.8)	(246.2)
Prior years' service gains(1)	14.0	13.1	12.2
Accrued healthcare liabilities/(surplus)	(65.5)	16.8	118.6
Obligations with salaries to suspended and pre-retired
employees	791.4	924.3	782.5
Unfunded liability for post retirement benefits—
Portuguese operations	1,490.8	966.9	928.7
Unfunded liability for post retirement benefits—Oi	—	—	61.7
Total accrued liability for post retirement benefits(2)	1,490.8	966.9	990.4

⁽¹⁾ These prior years' service gains resulted from the effect on unvested pension and healthcare benefits of changes in the plans governing those benefits. These amounts will be recognized in earnings during the estimated period in which those benefits will be earned by employees (9 years for pension benefits and 16 years for healthcare benefits).

(2) As of December 31, 2011, this caption corresponds to the net amount of an accrued post retirement liability of A1,004.1 million and a non-current asset of A13.6 million related to the surplus of certain pension plans.

Following the transfer of certain pension plans to the Portuguese State, we no longer sponsor any defined benefit plan relating to pensions, but we remain responsible for defined post retirement plans with respect to pension supplements and healthcare benefits. As of December 31, 2011, the projected benefit obligations (''PBO'') of our post retirement benefits for our Portuguese telecommunications business, including pension supplements, healthcare benefits and salaries for pre-retired and suspended employees, amounted to A1,256.6 million (A121.6 million for pension supplements, A352.6 million for healthcare benefits and A782.5 million for salaries to pre-retired and suspended employees). These projected benefit obligations were computed based on discount rates of 4.75% for pension supplements and healthcare benefits and 3.75% for obligations related to the payment of salaries to pre-retired and suspended employees, respectively, and assuming an annual salary increase of 1.75% for pension supplements and healthcare benefits and an annual salary increase ranging between 0% and 1% for salaries due to pre-retired and suspended employees, depending on the amount of the salary and the year of payment, as explained in more detail in Note 14.1 to our audited consolidated financial statements. As of December 31, 2011, our post retirement benefit plans related to our Portuguese telecommunications business, which are closed to new participants, covered approximately 19,624 employees in the case of pensions (around 36% still in service), and approximately 24,401 employees in the case of healthcare obligations (around 24% still in service).

According to the rules of the Instituto de Seguros de Portugal (ISP), the Portuguese insurance regulator, the liability related to retired employees under the pension plans must be fully funded. Under current rules, funding of pension funds for pre-retired employees and employees still in service can be completed up to the retirement age. The estimated average working life of employees still in service is 14 years. As of December 31, 2011, our pension obligations for retired employees, computed based on ISP rules, are fully funded.

In Portugal, there is no legislation on the establishment of funds to cover the healthcare obligations and the salaries for pre-retired and suspended employees. We are required to pay for these benefits only when the salaries are paid to pre-retired and suspended employees, or when healthcare expenses are incurred. Accordingly, there is no requirement to fund these benefit obligations at present. However, we have set up a fund managed by our subsidiary PT Presta¸coes—Mandat ˜ aria de ´ Aquisi¸coes e Gest ˜ ao de Bens, S.A., or PT Presta¸ ˜ coes, to finance our healthcare post-retirement ˜ liabilities. In previous years, we contributed A602 million to this fund, which is being managed in accordance with the same guidelines as our pension funds. In 2009, 2010 and 2011, we did not make additional contributions to this fund.

The market value of the pension funds for our Portuguese telecommunications business amounted to A344.7 million as of December 31, 2011, a decrease from A448.1 million as of December 31, 2010, primarily explained by (1) the negative performance of assets under management (A72.1 million), (2) a refund of healthcare expenses paid on account by Portugal Telecom (A23.3 million) and (3) payments of pension supplements (A9.7 million). See Note 14.1 to our audited consolidated financial statements. The asset allocation of our pensions and healthcare benefits funds as of December 31, 2011 was 17.8% equity, 43.0% bonds and 39.3% cash and others. The effective return of the funds in 2011 was negative by approximately 16.6%.

The accrued liability related to our total post-retirement benefits, related to both our Portuguese and Brazilian telecommunications businesses, amounted to A990.4 million (including A16.8 million of prior year service gains not recognized in our results of operations). In 2011, the accrued liabilities increased by A23.6 million, reflecting primarily (1) the impact of the proportional consolidation of Oi as from April 1, 2011 (A52.5 million) and (2) the increase in Oi's unfunded obligations during the nine months from April 1 to December 31, 2011 (A9.3 million), which was partially offset by a reduction in net accrued liabilities from Portuguese telecommunications business (A38.2 million). The reduction relating to our Portuguese telecommunications business is primarily explained by salary payments to suspended and pre-retired employees made during the period (A174.0 million), which were partially offset by total post retirement benefits and curtailment costs (A61.5 million) and net actuarial losses (A71.8 million) recognized in the period. The increase in unfunded obligations from Oi (A9.3 million) relates primarily to post retirement benefits costs (A4.5 million) and net actuarial losses (A8.7 million) recognized in the period, partially offset by the impact of the depreciation of the Brazilian Real against the Euro (A2.9 million).

The table below shows the evolution of our total net responsibilities for post retirement benefits, related to both our Portuguese and Brazilian telecommunications businesses, during the years ended December 31, 2010 and 2011.

(1) The prior year service gain recognized in 2010 is related to Portuguese Law 3B/2010, which introduced a maximum amount for pension benefits.

(2) This caption is related to the amortization of prior year service gains on unvested pension benefits.

(3) Oi's post retirement benefits costs include mainly interest cost (A69.3 million), the expected return on assets (A102.6 million) and a cap on recognition of plan assets pursuant to IFRIC 14 (cost of A36.0 million), as explained in more detail in Note 14.2 to our consolidated financial statements.

(4) This caption corresponds to our fixed monthly contribution to Social Security and Caixa Geral de Aposenta¸coes in order to fund future service of the active beneficiaries included ˜ in certain pension plans, following their transfer to the Portuguese State.

In 2009, 2010 and 2011, net curtailment costs amounted to A14.8 million, A145.5 million and A36.4 million, respectively. The higher level of costs recorded in 2010 reflects primarily a reduction in employees undertaken at the end of 2010.

The table below sets forth the components of our cash flows associated with post retirement benefits in 2009, 2010 and 2011.

• (1) In addition to these cash contributions, during 2009, we made contributions in kind (real estate assets) to the pension funds amounting to A33.0 million.
• (2) In 2010, this caption includes A75.0 million related to a refund of excess financing from the healthcare plan.
• (3) This caption corresponds to a fixed contribution paid to the Portuguese Social Security System relating to the annual service of active and suspended employees who were entitled to pension benefits under our post retirement benefit plans that were transferred to the Portuguese State in December 2010.

Our actuarial assumptions are subject to change, including the increase or decrease in the discount rates we use. In determining the appropriate discount rates for our Portuguese telecommunications business, we analyze, among other things, the yields of certain investment grade corporate bonds by issuers in the Eurozone with maturities comparable to those of our liabilities. We believe our actuarial assumptions are consistent with those commonly used in the Portuguese market. Note 14 to our consolidated financial statements contain sensitivity analyses that demonstrate the impact of increases or decreases in our discount rate assumption, our health care cost trend assumption and our assumption about the long-term rate of return on fund assets. Total net actuarial losses in 2011, related to both our Portuguese and Brazilian telecommunications businesses, amounted to A80.5 million, compared to net losses of A450.7 million in 2010.

Net actuarial losses totaled A80.5 million in 2011 and include losses from our Portuguese and Brazilian telecommunications businesses amounting to A71.8 million and A8.7 million, respectively. Net actuarial losses recorded by our Portuguese telecommunications business include (1) a gain of A19.4 resulting from changes in actuarial assumptions, corresponding to the impact of the reduction of the

salary increase rate on responsibilities for salaries payable to suspended and pre-retired employees and (2) a loss of A91.2 resulting from differences between actual data and actuarial assumptions, related mainly to the difference between actual (16.6%) and expected (+6.0%) returns on plan assets (loss of A98.2 million). Net actuarial losses from Oi amounting to A8.7 million include the impact of changes in actuarial assumptions (gain of A27.9 million) and differences between actual data and actuarial assumptions (loss of A108.1 million), as well as a cap effect on the recognition of plan assets pursuant to IFRIC 14 (gain of A71.4 million), as explained in Note 14.6 to our consolidated financial statements.

Net actuarial losses amounting to A450.7 million in 2010 included (1) a loss of A441.8 million resulting from changes in actuarial assumptions, reflecting primarily the reduction in the discount rate from 5.50% to 4.75% for pension and healthcare obligations and to 3.75% for salaries to pre-retired and suspended employees (A352.1 million) and an adjustment in the mortality tables (A100.0 million), and (2) a loss of A8.9 million resulting from differences between actual data and actuarial assumption, including a loss of A76.4 million related to the difference between actual (2.8%) and expected (6.0%) return on assets and a gain of A67.5 million related to the difference between actual data and actuarial assumptions related to projected benefit obligations, namely lower health care expenses and differences in the salary growth rate.

Equity

Our total equity excluding non-controlling interests amounted to A2,828.1 million as of December 31, 2011, A4,392.4 million as of December 31, 2010 and A1,318.3 million as of December 31, 2009.

The decrease in total equity excluding non-controlling interests in 2011 was primarily related to (1) the dividends paid to our shareholders in June 2011 (A1,118.0 million) and the interim dividends approved in December 2011 and paid in January 2012 (A184.8 million), (2) negative currency translation adjustments amounting to A280.7 million, mainly related to the impact of the depreciation of the Brazilian Real against the Euro, (3) the acquisition by Oi of Portugal Telecom shares (A148.3 million), which for accounting purposes are classified as treasury shares based on our interest in Oi, (4) net actuarial losses recognized in the period (A56.7 million, net of tax effect) and (5) a negative impact recorded directly in shareholders' equity resulting from the reassessment of the fair value of certain tangible assets recognized in accordance with the revaluation model (A94.6 million). These effects more than offset the net income generated in the period of A339.1 million.

The increase in total equity excluding non-controlling interests in 2010 was primarily related to (1) our net income for the period, amounting to A5,672.2 million and (2) positive currency translation adjustments amounting to A292.4 million primarily explained by the appreciation of the Brazilian Real against the Euro during the period. These effects more than offset (1) the dividends we paid to our shareholders, including ordinary and extraordinary dividends, totaling A1,379.5 million, (2) the accumulated currency translation adjustments relating to our former investment in Brasilcel (Vivo) that were transferred to net income upon our disposal of this investment, which amounted to A1,134.2 million as of the disposal date and (3) the net actuarial losses related to post retirement pension benefits in the amount of A338.0 million, net of taxes.

Our total equity excluding non-controlling interests as a percentage of total assets decreased from 29.0% at the end of 2010 to 12.3% at the end of 2011. Our gearing ratio, calculated as the ratio of net debt to total equity plus net debt, increased from 31.3% as of the end of 2010 to 63.9% as of the end of 2011, primarily as a result of the impact of the proportional consolidation of Oi and Contax as from April 1, 2011, which led to an increase in net debt.

Contractual Obligations and Off-Balance Sheet Arrangements

Contractual Obligations and Commercial Commitments

The following table presents our contractual obligations and commercial commitments as of December 31, 2011:

	Payments due by period in millions of Euros
	Total	Less than 1 year	1 - 3 years	4 - 5 years	More than 5 years
Contractual obligations:
Indebtedness	12,357.0	3,304.2	3,590.9	1,578.7	3,883.1
Interest on indebtedness(1)	2,878.5	670.1	1,019.9	560.8	627.7
Unfunded post retirement benefits(2)	1,226.2	184.8	327.7	253.2	460.6
Licenses and concessions(3)	507.8	127.1	141.8	111.9	127.0
Unconditional purchase obligations(4)	322.7	322.7	—	—	—
Operating lease obligations(5)	168.4	45.8	43.6	32.4	46.7
Total contractual cash obligations	17,460.6	4,654.7	5,123.9	2,537.0	5,145.0

(1) Interest on indebtedness is based on our indebtedness as of December 31, 2011, assuming that repayments will be made on scheduled dates and based on certain assumptions regarding interest rates on our floating rate debt. Therefore actual interest obligations could vary significantly from these amounts depending on future refinancing activities and market interest rates. These obligations relate exclusively to interest expenses on indebtedness and do not include any interest income on cash and cash equivalents and short-term investments.

• (2) These amounts primarily include the undiscounted payments to be made by PT Comunica¸coes ˜ related to salaries due to pre-retired and suspended employees and expected contributions to our pension funds, described above in ''—Post Retirement Benefits.'' The total amount relating to our Portuguese telecommunications business differs from the net accrued post retirement liability recognized in our consolidated statement of financial position primarily because the latter amount relates to the discounted unfunded obligations. In addition, this caption also includes expected contributions to cover the actuarial deficit of Oi's pension plans.
• (3) This caption includes (1) estimated bi-annual fees due to ANATEL under Oi's concession agreements equal to 2.0% of the net operating revenues of Brasil Telecom (now Oi S.A.), which are derived from the provision of local fixed-line services (excluding taxes and social contributions) and (2) payments due to ANATEL and ANACOM as of December 31, 2011 for radio frequency licenses (see Note 39 to our audit consolidated financial statements).
• (4) Unconditional purchase obligations primarily relate to contractual agreements with suppliers for the acquisition of tangible fixed assets and stocks, including amounts related to the acquisition of network assets, telecommunications equipment and terminal equipment.
• (5) Our operating leases relate to the contractual rental agreements entered into by our businesses and include obligations related to leased lines and the rental of buildings. Operating leases are accounted for as a cost in the period that the corresponding expense is incurred.

In addition to the commitments included in the table above, we have announced a shareholder remuneration package proposal that includes an ordinary cash dividend of A0.65 per share for the fiscal year ending December 31, 2011, of which A0.215 per share was paid in January 2012 and the remaining A0.435 per share was approved at the Annual Shareholders' Meeting held on April 27, 2012.

Our intention is to fulfill these commitments from our operating cash flow generated in each of those years.

Off-Balance Sheet Arrangements

In the course of our business, we provide certain guarantees to third parties. These guarantees are given to ensure the proper performance of contractual obligations by Portugal Telecom or its consolidated subsidiaries in the normal course of their business. As of December 31, 2011, in our Portuguese telecommunications business, we had provided bank guarantees to Portuguese courts and tax authorities in the amount of A273.7 million relating primarily to tax assessments, and we had provided bank guarantees on behalf of PT Comunica¸coes to municipal authorities, ANACOM and ˜ other entities (A21.8 million), on behalf of TMN to ANACOM and other entities (A17.2 million) and on behalf of other subsidiaries (A4.8 million). As of December 31, 2011, our proportionally consolidated portion of bank guarantees provided by Oi was A871.7 million relating primarily to deposits in connection with litigation, contractual obligations and obligations to ANATEL. For additional information on these bank guarantees, see Note 46 to our audited consolidated financial statements.

In addition to the bank guarantees described above, as of December 31, 2011, we had provided guarantees amounting to A439 million in favor of the EIB in connection with the loans obtained from this bank (see ''—Indebtedness—Covenants—Credit Ratings''). In addition, certain loans obtained by the Oi Companies, totaling A715 million, were collateralized by either receivables or by guarantees presented by the parent company or its subsidiaries.

Finally, as part of certain sale leaseback transactions entered into in previous years (Qualified Technological Equipment transactions, or ''QTE leases'') with third parties, in the past we have sold and then leased back certain telecommunications equipment. The flow of lease payments and our remuneration were prepaid at the outset of the contracts and, for this reason, are not shown as future lease payments in the table under ''—Contractual Obligations and Commercial Commitments'' above. The remuneration is recognized as income over the period of the transaction. We have recorded these QTE leases as an asset and the corresponding liability on our consolidated statement of financial position. During the year ended December 31, 2011, we terminated several of these QTE leases, and our only remaining QTE lease involves TMN. Under TMN's QTE lease, we have agreed with certain financial institutions to issue a letter of credit for the benefit of the trustee, which amounted to US\$5 million as of December 31, 2011, equivalent to A4 million at the exchange rate prevailing at year end. See Note 32 to our audited consolidated financial statements for more information about these transactions. In addition, we had bank deposits amounting to A3 million as of December 31, 2011, the use of which was restricted due to this QTE lease transactions.

We believe that our guarantees are part of our ordinary financing activities and therefore do not expect a material impact on our liquidity resulting from those guarantees.

Capital Expenditures and Financial Investments

The table below sets out our total capital investments related to continuing operations for 2009, 2010 and 2011:

	Year Ended December 31,

Capital Expenditures

During 2011, we made capital expenditures totaling A1,223.8 million. The table below sets forth our capital expenditures on tangible and intangible assets, excluding goodwill, for 2009, 2010 and 2011:

Year Ended December 31,

• (1) This caption excludes (1) real properties acquired from the pension funds in connection with the transfer of unfunded pension obligations to the Portuguese State (A226 million in 2010 and A3 million in 2011), (2) an intangible asset recognized by TMN in 2011 (A106 million) corresponding to the present value of the installments payable to ANACOM totaling A113 million related to the acquisition of TMN's LTE license, (3) the present value of the commitments assumed by PT Comunica¸coes in 2011 under its DTT ˜ license (A24 million) and (4) investments made in 2011 in a data center (A3 million).
• (2) This caption excludes the commitments under the terms of Cabo Verde Telecom's 3G license (A6 million in 2011) and a parcel of real estate acquired by a Portuguese company in connection with the transfer of unfunded pension obligations to the Portuguese State (A10 million in 2010).

Capital expenditures were A1,223.8 million in 2011, equivalent to 19.9% of total operating revenues, a decrease of 1.4 percentage points from 2010. The decrease in Portuguese telecommunications business capital expenditures from A657.2 million in 2010 to A647.0 million in 2011 was primarily explained by (1) a lower number of set-top-boxes per fiber TV customer as compared to ADSL customers, (2) a lower unitary cost of set-top-boxes, optical network terminators and home gateways and (3) improved refurbishment rates of set-top boxes. This decrease in customer-related capital expenditures was partially offset by the swap of TMN's 2G equipment for LTE (4G-enabled) equipment, and increased investments in capacity of existing 3G and 3.5G networks.

In 2011, our proportionally consolidated portion of Oi's capital expenditures as from April 1, 2011 were A444.3 million, equivalent to R\$1,034 million. The investments in Oi's fixed line network were aimed at (1) improving network quality and expanding coverage, (2) increasing speed of broadband services and (3) providing data packages to corporate customers. With respect to Oi's mobile network,

Oi focused on coverage expansion, encompassing all regions, and capacity of data traffic (3G) in strategic locations.

Other capital expenditures include capital expenditures related to consolidated businesses not included in our two reportable segments and support companies. In 2011, these other capital expenditures decreased to A132.5 million, compared to A141.2 million in 2010, primarily due to a lower contribution from Dedic/GPTI, which was fully consolidated until June 30, 2011 and then integrated into Contax, and lower capital expenditures at MTC in Namibia and CVT in Cape Verde. These effects more than offset the impact of the proportional consolidation of Contax as from April 1, 2011 (A29.7 million), including Dedic/GPTI as from July 1, 2011, and higher capital expenditures at Timor Telecom.

In 2012, we expect to make investments similar in nature (though amounts may vary) to those made in 2011. We generally fund our capital expenditures from cash flow generated by our operating activities and debt financing.

Financial Investments

Investments in financial assets (including goodwill) related to continuing operations amounted to A3,771.4 million in 2011, A3.7 million in 2010 and A10.6 million in 2009.

On July 28, 2010, we signed an agreement with Telefonica for the acquisition by Telef ´ onica of the ´ 50% of the capital stock of Brasilcel we owned. Brasilcel owned approximately 60% of the total share capital of Vivo. The price of such capital stock was A7,500 million, of which we received A4,500 million at the closing of the transaction on September 27, 2010, A1,000 million on December 30, 2010 and the remaining A2,000 million on October 31, 2011. The agreement also provided for certain other commercial arrangements between Telefonica and Portugal Telecom that were subsequently rendered ´ inapplicable. Upon the closing of the transaction, the respective subscription and shareholders agreements entered into by Telefonica and Portugal Telecom in 2002 relating to their joint venture in ´ Brazil were terminated.

On December 29, 2010, we reached an agreement for the disposal to a Brazilian businessman of our 28.78% interest in Universo Online S.A., Brazil's largest internet provider by revenue. The total consideration for the sale was R\$356 million (A155.5 million). The transaction closed on January 27, 2011.

As described in more detail under ''Item 4—Information on the Company—Our Businesses— Brazilian Operations—Strategic Partnership with Oi,'' on March 28, 2011, we completed the acquisition of a 25.3% economic interest in Oi and a 42.0% economic interest in Contax. We paid a total of R\$8,437 million (A3,728 million) in connection with these transactions.

In April 2011, Contax acquired an investment in Allus Global BPO Center for an amount of R\$245 million, and our proportionally consolidated amount was R\$103 million (A44 million). We proportionally consolidated the investment in Allus as from April 30, 2011 through our proportional consolidation of Contax.

Share Capital and Share Buyback Program

During the years ended December 31, 2011 and 2010 there were no changes in share capital. As of December 31, 2011, our fully subscribed and paid share capital amounted to A26,895,375, represented by 896,512,500 shares with a nominal value of A0.03 each.

In 2011, under the strategic partnership entered into between Portugal Telecom and Oi, Telemar Norte Leste, one of the Oi Companies, acquired 64,557,566 of our own shares, representing 7.2% of

our share capital, including A61.5 million related to shares acquired before the end of March 2011 and A86.8 million related to shares acquired in the second quarter of 2011.

Research and Development

In 2011, we invested approximately A219 million in innovation, research and development in Portugal, which translates into more than 5% of our total revenues, adjusted for the proportional consolidation of Oi and Contax. Our research and development programs in Portugal focus on intelligent networks, network management systems, advanced services and systems and network integration. Our research and development activities, carried out primarily through PT Inova¸cao, have ˜ been responsible for the introduction of innovative products and services and for the development of in-house technology. These activities have allowed our employees to remain up-to-date in terms of technology and technological development in the telecommunications sector on both a European and a worldwide level. PT Inova¸cao's activities have been a driving force behind the development of new ˜ products and services, telecommunications infrastructure and information systems.

We have developed narrow and broadband network access solutions for network operators and large customers and intelligent network solutions and services for fixed and mobile operators. We have also developed advanced Web functionalities, capitalizing on our extensive customer base and drawing on a crowdsourcing system.

In addition, we seek new solutions for the rational use of energy in our operations. The selective use of voltaic panels, wind-powered generators, hydrogen fuelcells and climatization systems has enabled greater cost containment and improved efficiency.

We participate in a number of EU research and development programs, including projects in the Information Society Technologies, ACTS and Telematics programs, with Eurescom, a joint venture with our European operators and the SURESCOM Institute. In addition, we work to develop programs in partnership with domestic research and development institutes, with the active involvement of Carnegie Mellon University.

Exchange Rate Exposure to the Brazilian Real

Our interest in Oi and Contax exposes us to significant exchange rate risk in respect of the Brazilian Real. We make adjustments to equity in response to fluctuations in the value of the foreign currencies in which we have made investments, including the Brazilian Real. See ''—Liquidity and Capital Resources—Equity'' above.

Currency Composition of Our Assets

The table below shows the amounts of our consolidated assets held in Euro and Brazilian Reais as of December 31, 2010 and 2011.

Exposure to Exchange Rate Risk

For more detailed information as of December 31, 2011 concerning our market exposure to exchange rate risk, as well as our market exposure to interest rate risk, see ''Item 11—Quantitative and Qualitative Disclosures About Market Risk.''

As a result of our investment in Oi, our investments in Brazil represent a substantial part of our assets. Given our substantial investments in Brazil, a devaluation of the Brazilian Real may have a significant impact on our statement of financial position and financial results. By the end of 2011, the exchange rate between the Euro and the Real was R\$2.4159 = A1.00. We cannot be sure that the value of the Real will remain stable, and if economic growth in Brazil were to slow, this could also have a significant impact on the growth prospects of the companies in which we have invested. We provide more information about the fluctuations in the Brazilian Real in ''Item 3—Key Information—Exchange Rates—Brazilian Real.''

Trend Information

We expect to continue to be a growth-oriented company, aiming to use full potential of our asset portfolio by taking advantage of existing and future opportunities in the telecommunications, multimedia and IT services markets. We aim to continue to take advantage of convergence opportunities by bundling traditional voice and data services with new and sophisticated multimedia and IT services.

Following the restructuring of our Portuguese business along customer categories, we will continue to focus our efforts on the development of fixed-mobile convergent products and services and integrated offers aimed at acquiring new customers, increasing share-of-wallet, improving customer loyalty and decreasing customer retention costs. We expect to continue to invest in innovation, research and development, aiming at enhancing our services with new, distinctive and customized features, functionalities and content tailored to meet customer needs. We expect to continue to leverage close partnerships with our suppliers in order to reduce time to market and further differentiate our value proposals to our customers. We expect to continue to invest to further develop new and more effective access and core networks and platforms, in fixed-line as well as in mobile, aimed at offering increased bandwidth to our customers. Furthermore, we expect to continue to rationalize our cost structure through productivity increases and business process reengineering.

With the establishment of our strategic partnership with Oi, we will continue to explore the growth potential of the Brazilian mobile and fixed line telecommunications market, leveraging Brazil's

favorable demographics and penetration growth potential, fixed-mobile migration and mobile broadband. To further exploit data services, we expect to continue to invest in the development of 3G and 3.5G services. Additionally, we intend to increase our exposure to high-growth markets in Africa by selectively considering value- creating opportunities and taking full advantage of our existing asset portfolio and partnerships. We expect to continue to promote the sharing of best practices among all of our assets, aiming at supporting our competitive position in all markets.

We will continue to operate in a highly competitive and regulated environment that will pose continued risks and threats to our existing businesses, placing the profitability of our assets under pressure. We expect our business to continue to be subject to the risks and uncertainties discussed in ''Item 3—Key Information—Risk Factors.''

ITEM 6—DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

Directors and Senior Management

Management Structure

The Board of Directors of Portugal Telecom is responsible for its management and affairs. Our officers are either in charge of our various business and administrative departments and report directly to the Executive Committee or are in charge of our subsidiaries.

According to our Articles of Association, the Board of Directors may be composed of 15 to 25 directors, including the Chairman. The directors are elected by a majority of the votes cast at an annual shareholders meeting. In addition, a majority of votes cast by holders of A shares is required to elect one-third of the members of the Board of Directors, including the Chairman of the Board. A minority of the shareholders representing, in the aggregate, at least 10% of our share capital, has the right to elect a director to substitute for the director elected by the fewest number of votes provided that they voted against the winning proposal in the election of the Board of Directors. The term of office of the directors is three calendar years, with the year of election or appointment considered a full calendar year. There is no restriction on the re-election of directors.

A quorum for a meeting of the Board of Directors is a simple majority of directors. All directors have equal voting rights, and all resolutions of the Board of Directors are adopted by a majority of the votes cast. The Chairman has the deciding vote in the event of a tie.

The articles of association provide for an Executive Committee of the Board to which the Board of Directors can delegate the day-to-day management of our businesses and the monitoring of our daily operations. However, the Board of Directors remains responsible for our overall management and operations. The Executive Committee may be composed of five or seven directors selected by a majority of the Board of Directors. From among the directors elected with the approval of a majority of holders of A shares, at least one or two must be appointed to the Executive Committee (depending on whether the Executive Committee is composed of five or seven directors). The vote of a majority of the members of the Executive Committee is necessary for the taking of an action by the Executive Committee. All members have equal voting rights, and the Chief Executive Officer has the deciding vote in the event of a tie.

The articles of association also provide for an Audit Committee composed of three non-executive members of the Board of Directors. The responsibilities of the Audit Committee are described below under ''—Board Practices.''

Board of Directors and the Executive Committee

Compensation

Board of Directors, Including Executive Committee

During the years ended December 31, 2011 and 2010, fixed compensation of board members (including members of our Executive Committee) amounted to A5.32 million and A6.68 million, respectively.

Under the terms of the compensation policy established by our Compensation Committee, executive board members are entitled to receive: (i) annual variable remuneration (''AVR'') related to the performance achieved in the year and payable in the following year, except for the amount in excess of 50% of the total variable remuneration attributed in the year, which payment is deferred for a period of 3 years; and (ii) variable remuneration related to medium-term performance (''VRMT''), which payment is deferred for a period of three years. In 2011, the annual variable remuneration of 2010 paid to the five executive board members amounted to A2.34 million, and in 2010, the annual variable remuneration of 2009 paid to the seven executive board members amounted to A3.52 million. In 2011 and 2010, there were no payments related to VRMT, and, under the terms of the approved remuneration policy of executive board members, the deferred payment of AVR and VRMT amounted to A4.28 million as of December 31, 2011, which is conditioned upon the positive performance of Portugal Telecom under the terms of the compensation policy in place. On an annual basis, we recognize an accrual for variable compensation.

Following the recommendation of some shareholders at the 2011 annual general meeting and based on a proposal of the Evaluation Committee, the Compensation Committee approved extraordinary variable remuneration payable to the Chairman and five Executive Committee members for their performance relating to the Vivo transaction and the acquisition of the strategic investment in Oi and Contax. Under the terms of the compensation policy of our board members, we paid to the Chairman and five Executive Committee members 50% of the above mentioned extraordinary variable compensation amounting to A2.55 million in 2011, and the payment of the remaining 50% was deferred for a period of three years, which is conditioned upon the positive performance of Portugal Telecom under the terms of the compensation policy in effect. Following the Vivo transaction and based on our Board of Directors' recommendation, in December 2010, the Executive Committee approved the payment to the majority of our employees of extraordinary variable compensation totaling A14 million.

In addition, in connection with the strategic partnership entered into with Oi and Contax, six of the members of our Board of Directors perform executive duties in these companies (entities jointly controlled by Portugal Telecom), and these board members received total fixed compensation of A1.21 million in 2011, which was established by the applicable corporate bodies in accordance with local legislation.

Since the approval of Law No. 28/2009 of June 19, 2009, we are required to report the compensation earned by individual members of our Board of Directors, including members of our Executive Committee. The tables below set forth the fixed and variable compensation received by these individuals for the period from January 1, 2011 through May 6, 2011 and from the period from May 6, 2011 (the date of the Annual Meeting of Shareholders for 2011) through December 31, 2011.

The annual variable paid in 2011 set forth above refers to the performance of the executive directors during the financial year ended on December 31, 2010. Members of our board who are non-executive directors were paid a monthly fixed amount taking into account our overall compensation policy, as well as the committee such director serves.

The compensation of executive directors takes into account the short and medium term performance of PT SGPS, as well as such performance when compared to other companies of a similar dimension and business. The compensation of Executive Directors is composed of a fixed portion and a variable portion as described below.

Components of Executive Committee Compensation

Fixed Compensation

The value of the fixed compensation of executive Directors was determined on the basis of a benchmark study. In this study, companies integrating the PSI20, IBEX35, CAC40, DJ Eurostoxx 50 were considered, as well as European telecommunications companies comparable to PT SGPS. In addition, the determination of the fixed component of the remuneration of executive Directors for the current term of office has taken into account the acceptance of the Chief Executive Officer's initiative to reduce his own fixed compensation in 10%, as compared to the one established for the previous term of office. Such reduction is applicable to all the members of the Executive Committee.

Variable Compensation

The variable compensation of Executive Directors, which depends on the pursuing of the determined goals, is composed of: (i) an annual variable compensation (''AVC'') that, in the event of a 100% pre-determined goal achievement, may amount to 90% of the fixed compensation, and (ii) a variable compensation associated to the medium-term performance (VRMT) that, in the event of a 100% pre-determined goal achievement, may reach 70% of the fixed compensation.

The determination of the AVC to be granted as a result of the performance in the 2009, 2010 and 2011 financial years is determined on the basis of a percentage of the annual fixed compensation, calculated through the weighted average of the level of achievement of any of the following indicators (with each one of such indicators being considered achieved only if at least 85% of the goals established for such indicator are reached), and if the company maintains the investment grade qualification at the end of each year (except if the loss of such qualification is a consequence of a strategic decision of the Board of Directors):

• Total shareholder return (''TSR'') ratio of PT SGPS as compared with the sector DJ Stoxx Telecom Europe (1st quartile), where the TSR is understood as the sum of the share price variation and the value of the dividend per share;
• Dividend per share delta to be adjusted if the Board of Directors amends the dividends policy;
• Earning per share (''EPS'') growth delta as compared to the budget;
• Revenues growth delta vis-a-vis a group of comparable companies, including KPN, Swisscom, ` TeliaSonera, Belgacom, Telenor, Telecom Austria and OTE;
• EBITDA growth delta vis-a-vis the same group of comparable companies; and `
• EBITDA growth delta minus CAPEX as compared to the budget.

In each year of the current term of office, the AVC should correspond to an amount of up to 50% of the total variable compensation allocated for the relevant financial year, and it is determined and paid in cash by the Company following the annual General Shareholder Meeting of approval of the accounts for the financial year to which such remuneration relates.

After determining the AVC in accordance with this methodology, the Compensation Committee may increase or reduce the variable remuneration of the Chief Executive Officer and of the other executive Directors, upon a proposal, respectively, of the Evaluation Committee of the Board of Directors and of the Chief Executive Officer. In any case and depending on the level of achievement of the pre-established goals, the AVC will not exceed the fixed compensation in more than 110%, and should it exceed 50% of the total variable compensation allocated in the year in question, the payment of the amount allocated in excess will be deferred for a period of 3 years.

The payment of the AVC amounts thus deferred will be made under the conditions provided for the payment of the variable compensation associated to the medium-term performance (MTVC) deferred amounts as established below.

MTVC is allocated on an annual basis (following the annual General Shareholder Meeting of approval of the accounts for the financial year to which such remuneration relates) as a function of the weighed average of the level of achievement of the following quantitative and qualitative indicators:

• Evolution of total shareholder return (''TSR'') compared with the sector DJ Stoxx Telecom Europe (1 st quartile);
• Dividend per share delta to be adjusted if the Board of Directors amends the dividends policy;
• Earning per share (''EPS'') growth delta as compared to the goal established in the Strategic Plan;
• EBITDA growth delta compared with the values prescribed in the Strategic Plan;
• Evolution of PT SGPS' Sustainability Index according to the DJSI methodology; and
• Fulfillment of national and international strategic goals.

The MTVC allocated each year further depends on the pursuing of the goals determined for the various indicators, with each indicator reaching at least 85% of the goals determined for such indicator.

After the determination of the MTVC in accordance with this methodology, the Compensation Committee may increase or reduce the variable compensation of the Chief Executive Officer and of the other executive directors, upon proposal of the Evaluation Committee of the Board of Directors and of the Chief Executive Officer, respectively. In any case and depending on the level of achievement of the pre-established goals, the MTVR will not exceed the fixed remuneration in more than 88%.

The payment of the AVC amounts in excess of 50% of the total variable remuneration allocated in the relevant year and of the MTVC amounts allocated will be deferred for a period of 3 years, and it is further subject to the condition of the Company's positive performance during the deferment period not being proven to be affected as a direct result of the conduct of the Director concerned.

In the event the office of the executive Director is terminated, for any reason whatsoever, the payment of the AVC or MTVC amounts granted and deferred will be made at the time of termination of the management relationship.

In addition to the compensation described above, Executive Committee members and key employees are also entitled to fringe benefits that are primarily utilized in their daily functions, pursuant to an internal policy for the Portugal Telecom Group. As of December 31, 2011, there were no members of our Board of Directors entitled to post-retirement benefits under the plans of PT Comunica¸coes. ˜

The Chairman of our Board of Directors and certain members of our Executive Committee are parties to contracts that entitle them to receive the equivalent of between one and two years' salary (and, in some cases, variable compensation) if they are not reelected to those offices, the most recent of which was signed in April 2006. In return, those parties agree not to compete with the Company for a specified period following the time they cease to hold office with the Company. In addition, if the Company terminates any such person without cause, the person has the right to receive the salary (and, in some cases, variable compensation) that he would have received if he had completed his three-year term.

Compensation Committee

We have a Compensation Committee consisting of three members whose functions include: (1) to establish the compensation for members of our corporate bodies and (2) to follow up and evaluate the performance of our directors with reference to our business goals. As of December 31, 2011, the members of the Compensation Committee are Alvaro Jo ´ ao Duarte Pinto Correia (Chairman of the ˜ Compensation Committee), Francisco Adelino Gusmao Esteves de Carvalho and Francisco Jos ˜ e ´ Queiroz de Barros Lacerda. The Compensation Committee approves the model to be used to calculate variable compensation for each fiscal year and approves the value of the variable compensation to be paid to the Chairman of the Board of Directors and the members of the Board of Directors who are executive officers.

The Compensation Committee determines the compensation of the members of the Executive Committee based on objective criteria approved by the Compensation Committee and on the evaluation of the performance of executive directors carried out by the Evaluation Committee described in ''Item 10—Additional Information—Corporate Governance—Other Committees and Functions—Evaluation Committee,'' within the framework of its specific powers, upon hearing the Chief Executive Officer. For more information about standards for membership on the Compensation Committee, see ''Item 10—Additional Information—Corporate Governance—Summary of Significant Differences Between Portuguese Corporate Governance Practices and the New York Stock Exchange's Corporate Governance Standards—Committees Created by the Annual General Meeting of Shareholders— Compensation Committee.''

The executive directors are evaluated within the scope of the performance evaluation of the Board of Directors itself. Furthermore, pursuant to Portuguese law, the Annual Meeting of Shareholders makes an annual general appraisal of the management (and supervision) of our company.

The criteria established by the Compensation Committee for evaluation of the performance of executive directors as a function of the goals defined by the Evaluation Committee are described in greater detail in the Corporate Governance Report for 2011 that we are required to prepare under Portuguese law and that will be publicly available on our website at www.telecom.pt. Copies of the Corporate Governance Report are also available without charge upon request to our Investor Relations office.

The relative significance of the variable and fixed components of director compensation, as well as an indication of the maximum limits for each component, are described in the compensation policy set forth in our Corporate Governance Report.

Executive management member compensation components take into account our performance, in the short and medium-term, as well as the benchmarking of performance compared to other companies of a similar size and business.

Key Employees

In addition to our directors, we have certain key employees that include (1) the officers described above which are in charge of our various businesses and administrative departments and report directly to the Executive Committee, (2) the Chief Executive Officers of our major subsidiaries described above, and (3) other directors of our major subsidiaries which are not described above. In 2011, fixed compensation of key employees of the Portugal Telecom group management amounted to A5.6 million, and variable compensation amounted to A3.6 million, compared to fixed compensation of A6.9 million and variable compensation of A3.4 million in 2010.

The fixed and variable compensation of the Portugal Telecom Group officers is determined for each Group operating company by a compensation committee of two officers of Portugal Telecom and a human resources manager.

Four of our key employees also participate in the PT Comunica¸coes pension plan. For these key ˜ employees, amounts were accrued in respect of post-retirement benefits. The total amount accrued to provide benefits under the plan for these key employees as as of December 31, 2011 was A0.5 million. For information regarding our post-retirement benefit payments and obligations generally, see ''Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources— Post-Retirement Benefits.''

As of December 31, 2011, there was no share-based payment program.

Board Practices

We are required by our articles of association and Portuguese law to maintain an Audit Committee consisting of three non-executive board members. In addition to the authority established in Portuguese laws, the Audit Committee has specific authority granted by our articles of association, including the powers listed in ''Item 10—Additional Information—Corporate Governance—Summary of Significant Differences Between Portuguese Corporate Governance Practices and the New York Stock Exchange's Corporate Governance Standards—Composition of Board of Directors and Independence; Meetings of Non-Management Directors; Committees.''

As of December 31, 2011, Joao Manuel de Mello Franco, Jos ˜ e Guilherme Xavier de Basto and ´ Mario Jo ´ ao de Matos Gomes were the members of our Audit Committee responsible for the oversight ˜ of our management.

In addition to an Audit Committee, our bylaws provide for a Statutory Auditor. The Statutory Auditor, who, pursuant to Decree-Law 76-A/2006 dated March 29, 2006, is not a member of the audit committee, is responsible for examining our accounts. As of December 31, 2011, P. Matos Silva, Garcia Jr., P. Caiado & Associados SROC, Lda., represented by Pedro Joao Reis de Matos Silva, was ˜ our effective Statutory Auditor. As permitted by law, no Alternate Statutory Auditor was appointed at our last general shareholders' meeting.

The Audit Committee schedules its meetings at least once every two months of each financial year at the time and place determined by its Chairman, and additional meetings may be convened by the Chairman or at request of the majority of its members. The Audit Committee may not meet without the attendance of the majority of its members, provided that the Chairman may, in cases of recognized urgency or justified impossibility, permit a meeting without the attendance of a majority if a majority is assured by vote by correspondence or by proxy (provided, however, that each member does not act on behalf of more than one Audit Committee member). The resolutions of the Audit Committee are adopted by the majority of votes cast and its Chairman has a deciding vote.

In our annual budget, we provide the financial resources required for the audit committee to pay the compensation of the independent auditor and of any advisors of the audit committee and to cover the expenses required for the audit committee to perform its powers and duties.

Related Party Transactions Policies

Since 2006, we have followed a policy on transactions with related parties aimed at ensuring the correct identification and disclosure of transactions with related parties, as well as defining the relevant concepts of ''transaction'' and ''related parties.'' This policy pursues a dual purpose: (1) enabling our financial statements to disclose the existence of related party transactions and their pending balances and (2) safeguarding our interests in potential conflict of interest situations vis-a-vis the interests of ` persons or entities who may have the ability to influence, directly or indirectly, our management.

Such rules provide for internal control procedures and mechanisms that ensure the proper identification and disclosure of transactions with related parties, involving the identification of the transactions, transparency in the transaction decision-making process and, if required, disclosure according to the Portuguese Securities Code and the rules of the Portuguese Securities Commission (CMVM) and the SEC.

In December 2009 and December 2010, we modified our policy on transactions with related parties, primarily to adjust it in light of amendments to IAS 24 and to the recommendations issued by CMVM on this matter. The most significant modification consisted of providing rules for the prior assessment by the Audit Committee of the execution of certain related party transactions where some material requirements as described in the policy are met.

As a result, the execution of any transaction with related parties the value of which is in excess of A100,000 is now subject to prior favorable opinion of the Audit Committee. The Audit Committee's opinion must confirm that, in view of the justifications submitted, the proposed transaction complies with the rules on conflicts of interest and observes the principle of equal treatment of suppliers or service providers of the Portugal Telecom Group, notably as to the agreed terms and conditions.

Furthermore, transactions with shareholders who are owners of a qualified holding percentage or with special voting rights, with their relatives or with entities in a relationship as provided for under

article 20 of the Portuguese Securities Code with the said shareholders or relatives, the aggregate amount of which exceeds A1,000,000 per year, are subject to approval by our Board of Directors.

Transactions with directors either of Portugal Telecom or of our subsidiaries, irrespective of the amounts involved, are also subject to the prior approval by the applicable Board of Directors, upon the favorable opinion of the applicable supervisory corporate body, as provided for under Article 397 of the Portuguese Companies Code.

Transactions with related parties are identified as established by law and are disclosed in the annual, interim and quarterly financial information.

These amounts included A140.2 million relating to civil claims, A256.6 million relating to labor claims and A1,949.0 million relating to tax claims, respectively, that reflect the proportional consolidation of Oi and Contax.

See Note 49 to our audited consolidated financial statements for more information on our pending legal proceedings.

Claims for Municipal Taxes and Fees in Our Portuguese Telecommunications Business

Pursuant to a statute enacted on August 1, 1997, as an operator of a basic telecommunications network, we were exempt from municipal taxes and rights-of-way and other fees with respect to our network in connection with our obligations under our concession. The Portuguese government has advised us in the past that this statute confirmed the tax exemption under our concession. The Portuguese government has advised us it will continue to take the necessary actions in order for us to maintain the economic benefits contemplated by our concession. However, we cannot be sure that the Portuguese courts will accept that this statute resolves claims for municipal assessments and taxes for the period prior to its enactment.

Law 5/2004 of February 10, 2004 established a new rights-of-way regime in Portugal whereby each municipality may establish a fee, up to a maximum of 0.25% of each wireline services bill, to be paid by the customers of those wireline operators whose network infrastructures are located in each such municipality. This regime was implemented in 2005 but some municipalities interpret Law 5/2004 as

having no effect on their authority to establish other taxes but rather interpret Law 5/2004 as affecting only federal and regional taxing authorities. In 2009, Decree-Law 123/2009, of May 21, 2009, clarified that no other tax should be applicable by municipalities in addition to the regime established by Law 5/2004 of February 10, 2004. This interpretation was confirmed by the Supreme Administrative Court of Portugal in several cases. Some municipalities, however, continue to hold the position that the Law 5/2004 does not expressly revoke other taxes that the municipalities wish to establish, because Law 5/2004 is not applicable to the public municipality domain. Currently, there are legal actions filed by some municipalities against PT Comunica¸coes regarding this matter. ˜

Regulatory Proceedings in Our Portuguese Telecommunications Business

We are regularly involved in regulatory inquiries and investigations involving our operations. In addition, ANACOM, the European Commission and Autoridade da Concorrencia regularly make ˆ inquiries and conduct investigations concerning our compliance with applicable laws and regulations.

Autoridade da Concorrˆencia

Current inquires and investigations by the Autoridade da Concorrencia include, among others, the ˆ following:

• PT Comunica¸coes regarding alleged anti-competitive practices in the broadband internet market ˜ (this complaint was formerly against Telepac, which merged with a PT affiliate that later merged into PT Comunica¸coes and TV Cabo, which we spun off as part of PT Multimedia in 2007). ˜ Specifically, the Autoridade da Concorrencia alleged that our ''Rede ADSL PT'' wholesale offer ˆ of broadband services between May 22, 2002 and June 30, 2003 did not allow the remaining competitors to generate a sufficient profit margin. In September 2009, we announced that we had been notified by Autoridade da Concorrencia that it had concluded its investigation and had ˆ decided to impose a fine of A45.0 million on us. We strongly disagreed with this ruling and appealed the decision to the Commercial Court of Lisbon (Tribunal de Com´ercio) later that month. We believed, among other things, that the wholesale offer was permitted under the competition law then in force (DL 371/2003) and was supervised by ANACOM. In addition, we have argued that the wholesale offer was maintained in place for 14 days after the new competition law was approved (Lei 18/2003) only to permit ANACOM to determine the terms of the new offer and that the fine imposed exceeds the maximum A1 million fine allowed under the prior competition law. In 2011, we were notified of a decision of the Commercial Court of Lisbon that terminated this proceeding for prescription purposes, as from June 30, 2011. We had not recorded any provision for this matter based on the opinion of our internal and external legal counsel.
• PT Comunica¸coes for alleged anti-competitive practices in the public wireline telephone market ˜ and for granting discriminatory discounts on leased lines. In 2007, the Autoridade da Concorrencia accused PT Comunica¸ ˆ coes of alleged abuse of dominant position for granting ˜ discriminatory discounts on leased lines. In September 2008, PT Comunica¸coes was notified by ˜ Autoridade da Concorrencia of its decision imposing a fine of ˆ A2.1 million for PT Comunica¸coes' alleged abuse of its dominant position in the lease line segment. PT ˜ Comunica¸coes considers these allegations unfounded and appealed the fine to the Commercial ˜ Court of Lisbon later that month. On February 29, 2012, the Commercial Court of Lisbon cleared PT Comunica¸coes of the fine imposed by the Autoridade da Concorr ˜ encia in September ˆ 2008. We had not recorded any provision for this matter based on the opinion of our internal and external legal counsel.

We believe that the Portugal Telecom group has consistently followed a policy of compliance with all relevant laws. We continually review our commercial offers in order to reduce the risk of

competition law infringement. We believe that most of the complaints that have resulted in such investigations should be dismissed due to the nature of the alleged abuses. However, if we are found to be in violation of applicable laws and regulations in these or other regulatory inquiries and investigations, we could become subject to penalties, fines, damages or other sanctions.

European Commission

On January 19, 2011, the European Commission opened an investigation into an agreement between Telefonica and Portugal Telecom allegedly not to compete in the Iberian telecommunications ´ markets. Portugal Telecom has developed various strategic partnerships with Telefonica in recent years. ´ Although we do not believe the existence of these partnerships has impeded competition and ordinary activities of our company and Telefonica, our relationship with Telef ´ onica is now subject to ´ investigation. The European Commission has stated that the initiation of proceedings does not imply that the Commission has conclusive proof of an infringement but that the Commission will deal with the case as a matter of priority. On October 25, 2011, we were notified of a Statement of Objections sent by the European Commission to us and Telefonica on the matter. The Statement of Objections only covers alleged cooperation between the two companies after the Vivo transaction. In response to the Statement of Objections, we contested the allegations of the European Commission. The sending of a Statement of Objections does not prejudge the final outcome of the investigation.

On a separate matter, we understand that the Directorate General for Information Society of the European Commission requested information in the past from the Portuguese government regarding the designation of the universal service provider in Portugal (currently, PT Comunica¸coes) and ˜ regarding the Portuguese government's intention to launch a transparent procedure to appoint the universal service provider. We understand that in January 2009, the European Commission referred the case to the European Court of Justice. On October 7, 2010, the European Court of Justice ruled that by failing to correctly transpose into national law the provisions of European Union law governing the designation of universal service providers, the Portuguese Republic failed to fulfill its obligations under Articles 3(2) and 8(2) of Directive 2002/22/EC of the European Parliament and of the Council of March 7, 2002 on universal service and users' rights relating to electronic communications networks and services (Universal Service Directive). ANACOM has now held a public consultation on the process for selecting a universal service provider, as described in ''Item 4—Information on the Company— Regulation—Portugal—Universal Service Obligations.'' The Portuguese government is expected to launch a tender in 2012 for the designation of the universal service providers.

In April 2006, the European Commission sent to the Portuguese government a formal request to abandon the special rights the Portuguese government holds as the sole owner of our A shares. The European Commission viewed the special powers granted to the Portuguese government through the sole ownership of our A shares act as a disincentive for investment by other EU member states in a manner that violated European Community Treaty rules. The Portuguese authorities initially took the position that these special rights are justified in order to protect relevant public interests. In 2008, the European Commission referred the case to the European Court of Justice, and in 2009, the Advocate General in charge for the case issued an opinion stating that the Portuguese Government's ownership of our A shares did not comply with the European rules on the free movement of capital. At an Extraordinary Shareholders' Meeting held on June 30, 2010, the Portuguese Government used its A shares to reject an offer by Telefonica S.A. to purchase our interest in Brasilcel N.V., the joint ´ venture that held our interest in Vivo, even though 73.9% of the ordinary shareholders present at the meeting voted in favor of Telefonica's offer. On July 8, 2010, the European Court of Justice ruled that ´ the Portuguese Government's ownership of our A shares was illegal under European law. Following the European Court of Justice decision, on July 26, 2011, our General Meeting of Shareholders approved the amendment of the Company's Bylaws and eliminated the special rights granted to the 500 class A shares of stock held by the Portuguese Government.

Other Legal Proceedings in Our Portuguese Telecommunications Business

In March 2004, TVTEL Grande Porto—Comunica¸coes, S.A. (''TVTEL''), a telecommunications ˜ company based in Oporto, filed a claim against PT Comunica¸coes in the Lisbon Judicial Court. TVTEL ˜ alleged that PT Comunica¸coes, since 2001, has unlawfully restricted and/or refused access to the ˜ telecommunication ducts of PT Comunica¸coes in Oporto, thereby undermining and delaying the ˜ installation and development of TVTEL's telecommunications network. TVTEL alleges that PT Comunica¸coes intended to favor both itself and TV Cabo. TVTEL is claiming an amount of ˜ approximately A15 million from Portugal Telecom for damages and losses allegedly caused and yet to be sustained by that company as a result of the delay in the installation of its telecommunications network in Oporto. In addition, TVTEL has demanded that PT Comunica¸coes be required to give full access to ˜ its ducts in Oporto. PT Comunica¸coes submitted its defense to these claims in June 2004, stating that ˜ (1) TVTEL did not have a general right to install its network in PT Comunica¸coes's ducts, (2) all of ˜ TVTEL's requests were lawfully and timely responded to by PT Comunica¸coes according to its general ˜ infrastructure management policy and (3) TVTEL's claims for damages and losses were not factually sustainable. The trial was concluded in 2011, and we are awaiting a judicial decision.

In March 2011, Optimus—Comunica¸coes S.A. (''Optimus'') filed a claim against us in the Judicial ˜ Court of Lisbon for the payment of approximately A11 million, and in October 2011, Onitelecom— Infocomunica¸coes, S.A (''Oni'') also filed a claim against us in the same court for the payment of ˜ approximately A1.5 million, both related to the proceeding of the Autoridade da Concorrencia that ˆ terminated in 2011 for prescription purposes, in relation to which Autoridade da Concorrencia had ˆ imposed a fine to Portugal Telecom of approximately A45 million, as described above. Optimus and Oni supported their position by arguing that they suffered losses and damages as a result of our conduct. We countered all the arguments presented by Optimus and Oni and, based on the opinion of our internal and external legal counsel, have not recorded any provision for this matter.

Oi Legal Proceedings

Proceedings Accounted for as Involving Probable Losses

Civil Proceedings

As of December 31, 2011, Oi and Contax had recorded provisions in the amount of R\$4,165.5 million for civil proceedings in respect of which they deemed the risk of loss to be probable, including the corporate law proceedings and ANATEL estimates and fines described below.

Corporate Law Proceedings. As a successor to CRT, which was acquired in July 2000, Oi is subject to various civil claims. The claims, filed in 1998 and 1999, allege (1) errors in the sale of CRT's share capital, (2) the illegality of the bidding procedure , (3) errors in the calculation of the number of shares offered, (4) procedural nonconformities in the shareholders' meeting that approved the sale of shares of CRT and (5) errors in the valuation of the shares of CRT. Oi is also a defendant in several claims filed against CRT filed by users of telephone lines in the State of Rio Grande do Sul. CRT entered into financial interest agreements with its fixed-line subscribers. Under these financial interest agreements, customers had the right to subscribe to a number of CRT shares, with the number of shares to be issued to each subscriber to be determined based on a formula that divided the cost of the fixed-line subscription by the book value of CRT's shares. Beginning in June 1997, certain of CRT's fixed-line subscribers filed lawsuits in which they claimed that the calculation used by CRT to arrive at the number of shares to be issued pursuant to the financial interest agreements was incorrect and resulted in the claimants receiving too few shares.

In addition, as successor to Telecomunica¸coes do Mato Grosso do Sul S.A. (''Telems''), ˜ Telecomunica¸coes de Goi ˜ as S.A. (''Telegoi ´ as'') and Telecomunica¸ ´ coes do Mato Grosso S.A. ˜ (''Telemat''), operating companies acquired by Brasil Telecom Holding in the privatization of Telebras´ and which were subsequently merged into Oi, Oi is subject to various civil claims in connection with community telephone programs established in the States of Mato Grosso do Sul, Goias and Mato ´ Grosso.

Based on the decisions of the Brazilian Court of Justice issued in 2009, Oi considers the risk of loss regarding these proceedings to be probable. Currently, the provisions for these lawsuits are based on (1) applicable legal interpretations, (2) the number of ongoing lawsuits and (3) the average amount of historical losses, broken down by matter (including all procedural costs).

As of December 31, 2011, Oi recorded provisions in the amount of R\$2,350.1 million for those claims in respect of which it deemed the risk of loss as probable.

ANATEL Estimates and Fines. Almost every week, Oi receives notifications from ANATEL requesting information about its compliance with the various services obligations imposed on it by virtue of its concession agreements. When Oi is not able to comply with these requests or with its concession obligations, ANATEL may initiate administrative proceedings to impose sanctions on it. Oi has received various notifications, mainly for not meeting certain goals or obligations set out in the General Plan on Universal Service or the General Plan on Quality Goals, such as responding to complaints relating to billing errors, requests for service repairs on a timely basis and requests from locations with collective or individual access. As of December 31, 2011, Oi recorded provisions in the amount of R\$941.0 million for those claims in respect of which it deemed the risk of loss as probable.

Labor Proceedings

Oi is a party to a large number of labor claims arising out of the ordinary course of its businesses, including claims for:

• Overtime—Lawsuits claiming the payment of overtime, for time allegedly worked after regular working hours.
• Salary differences and related effects—Primarily representing amounts arising from salary equalization/reclassification differences claimed by employees who allegedly received lower compensation than coworkers holding similar positions.
• Hazardous work conditions—Primarily reflecting the expected unfavorable outcome of lawsuits on the mandatory payment of hazardous duty premium to employees working under conditions classified as hazardous, mainly next to high-voltage installations.
• Indemnities—Reflecting reimbursement of or compensation claims for damages suffered while employed by Oi for reasons such as occupational accidents, temporary tenure, pain and suffering, reimbursement of payroll deductions, daycare allowance, and productivity bonuses according to collective bargaining agreements.
• Stability and integration—Relating to alleged non-compliance with an employee's special condition which prohibited termination of the employment contract without cause.
• Additional post retirement benefits—Relating to differences allegedly due in pension benefits of former employees.
• Lawyers and expert fees—Installments paid to the plaintiffs' lawyers and appointed court experts, when expert evidence is necessary during the fact-finding stage.
• Contractual rescissions—Amounts due to claimants arising from the termination of employment contracts, such as vacation pay (proportional/vested), thirteenth salary fines and the increase in pay proportionate to other amounts claimed that allegedly should be included in the calculation of severance pay.

• Other labor contingencies—Primarily including joint liability allegations by employees of thirdparty service providers, lawsuits related to differences owed on the deposits in the claimant's severance pay fund (FGTS) and labor fines arising from delays or non-payment of certain amounts provided for by the employment contract.

As of December 31, 2011, the total estimated contingencies in connection with labor claims against Oi and Contax in respect of which the risk of loss was deemed probable totaled R\$1,980 million.

Tax Contingencies

As of December 31, 2011, Oi and Contax had recorded provisions in the amount of R\$915.1 million for tax proceedings in respect of which they deemed the risk of loss to be probable, including the proceedings described below.

• ICMS (Value Added Tax). Under the regulations governing ICMS, in effect in all Brazilian states, telecommunications companies must pay ICMS on every transaction involving the sale of telecommunication services they provide. Oi may record ICMS credits for each of its purchases of operational assets. The ICMS regulations allow Oi to apply the credits it has recorded for the purchase of operational assets to reduce the ICMS amounts it must pay when it sells its services. Oi has received various tax assessments challenging the amount of tax credits that it recorded to offset the ICMS amounts it owed. Most of the tax assessments are based on two main issues: (1) whether ICMS is due on those services subject to the Local Service Tax (Imposto Sobre Servi¸cos de Qualquer Natureza—''ISS'') and (2) whether some of the assets it has purchased relate to the telecommunication services provided, and, therefore, eligible for an ICMS tax credit. As of December 31, 2011, Oi recorded provisions in the amount of R\$605 million for those assessments in respect of which it deemed the risk of loss as probable.
• FUNTTEL. The Fundo para o Desenvolvimento Tecnologico das Telecomunica¸ ´ coes ˜ (''FUNTTEL'') is a fund that was established to finance telecommunications technology research, for which Oi is required to make contributions. Due to a change by ANATEL in the basis for calculation of its contributions to the FUNTTEL, whose legality Oi has questioned, Oi recorded provisions for additional contributions to these funds. As of December 31, 2011, Oi recorded provisions in the amount of R\$121 million for assessments of the FUNTTEL.

Proceedings Accounted for as Involving Possible Losses

Civil Proceedings

Oi's civil proceedings that it has classified as involving possible losses consist of lawsuits for which no court decision has been issued and are primarily related to issues such as challenges to network expansion plans, compensation for pain and suffering and material damages, collection lawsuits and auction processes, among other matters. The total amount of civil proceedings that Oi and Contax have classified as involving possible losses was R\$1,297.1 million as of December 31, 2011. This total amount is based exclusively on the amounts claimed by the plaintiffs, which are typically higher than amounts actually recovered.

These civil proceedings also include certain ongoing litigation with committed subscribers and assignees of committed subscribers of fixed telephone services in Region I of Brazil who allege non-compliance with certain financial participation agreements prior to the privatization of fixed telephone services. These lawsuits involve approximately 50,000 agreements, and Oi has not recorded any provision because its legal counsel assesses the risk of loss as possible. As the lawsuits related to these agreements have not yet gone to trial, it is not practicable to measure possible disbursements in such lawsuits.

In addition, in September 2004, the Federal Public Prosecution Office and the Rio de Janeiro State Public Prosecution Office filed a civil suit against TNL, Telemar, TNL PCS and the Brazilian federal government requesting the annulment of the transfer of the TNL PCS share control to Telemar and the payment of compensation for pain and suffering and material damages allegedly inflicted upon non-controlling shareholders and the financial market. The sale of control of TNL PCS to Telemar is also challenged by two non-controlling shareholders and by the CVM in an administrative proceeding filed to determine whether there were any irregularities in the transaction. Oi originally deemed the risk of loss of those two claims to be possible. These three claims were judged unfounded by the lower court, and, accordingly, Oi's legal counsel reassessed the possibility of loss from possible to remote.

In July 2009, a class civil action was filed against Telemar by the Brazilian federal government, the Federal Public Prosecution Office, the Federal District and Territories Public Prosecution Office, customer protection bodies and several State Consumer Protection Agencies seeking compensation for alleged collective pain and suffering caused by non-compliance of the rules to establish general customer service standards. Telemar filed its defense arguments on September 16, 2009 and awaits the lower court decision.

Telemar and its subsidiaries are subject to administrative proceedings and preliminary investigations conducted by the Brazilian antitrust authorities with respect to alleged violations of the Brazilian antitrust law. These investigations may result in penalties, including fines. To date, no fines or penalties have been levied against Telemar and its subsidiaries. Oi has deemed the risk of loss to be possible that it will be fined in one or more of such proceedings and has not recorded any provisions for those claims.

Labor Proceedings

Oi is subject to various labor lawsuits for which it has deemed the risk of loss to be possible. The total amount of labor proceedings that Oi and Contax have classified as involving possible losses was R\$1,930.7 million as of December 31, 2011. These lawsuits include claims similar to those described under ''—Proceedings Accounted for as Involving Probable Losses—Labor Proceedings'' above.

Tax Contingencies

As of December 31, 2011, the estimated contingencies in connection with tax proceedings against Oi and Contax in respect of which the risk of loss was deemed possible amounted to R\$18,276 million. The Brazilian corporate tax system is complex, and Oi and Contax are currently involved in tax proceedings regarding certain taxes that the companies believe are unconstitutional and have filed claims to avoid the related payment. These tax contingencies relate primarily to the following:

• ICMS (Value-Added Tax)—Tax assessments amounting to R\$5,646 million, which relate mainly to (1) ICMS levied on certain revenue from services already subject to ISS or which are not part of the ICMS tax base and (2) utilization of ICMS credits on the purchase of goods and other inputs necessary for network maintenance.
• City Taxes—Tax assessments related to taxes levied by municipal authorities, including taxes levied on equipment leases, wakeup call services and other communication services. The total amount involved is R\$2,487 million, and the companies have not recorded provisions because their legal counsel consider the likelihood of an unfavorable outcome possible, rather than probable, as these activities do not qualify under the ISS service list or are already subject to ICMS.
• INSS (Brazilian Social Security)—Pursuant to Brazilian social security legislation, companies must pay contributions to the National Social Security Institute (Instituto Nacional do Seguro Social) (''INSS'') based on their payroll. In the case of outsourced services, the contracting parties must,

in certain circumstances, withhold the social contribution due from the third-party service providers and pay the retained amounts to the INSS. In other cases, the parties are jointly and severally liable for contributions to the INSS. Assessments have been filed against Oi primarily relating to claims regarding joint and several liability and claims regarding the percentage to be used to calculate workers' compensation benefits and other amounts subject to social security tax. Lawsuits amounting to R\$1,590 million, mainly related to joint liability, the applicable percentage of Occupational Accident Insurance (SAT) and amounts subject to social security contributions.

• Other Federal Taxes—Federal tax assessments, mainly related to alleged undue offsets and self-assessments of taxes due, or disallowing previous calculations, amounting to R\$6,085 million.

Judicial Deposits

Under Brazilian law, courts may require parties to make judicial deposits or to present financial guarantees in connection with legal actions for which risk of loss is deemed probable, possible or remote. As of December 31, 2011, Portugal Telecom's proportionally consolidated portion of the judicial deposits recorded by Oi and Contax amounted to A1,084.1 million, which we record as an asset on our consolidated balance sheet. For more information about these judicial deposits, see Note 31, to our audited consolidated financial statements.

Distributions to Shareholders

Dividend Information

Our policy has been to propose an annual dividend subject to its financial and economic condition, but in no event less than 40% of its distributable net income. Should Portugal Telecom undertake to change this policy, the Board of Directors will submit its recommended changes to its shareholders for their approval at our Annual General Meeting. For 2012, the Annual General Meeting of Shareholders was held on April 27, 2012.

Our ordinary shares and A shares carry the same dividend rights. Our Board of Directors decides whether to propose a dividend. Under our articles of association, we must pay dividends of at least 40% of its annual distributable net income to shareholders, subject to a two-thirds majority of our shareholders to vote to reduce the dividend or not to pay a dividend. Under Portuguese law and the articles of association, distributable net income is net income after covering accumulated losses and setting aside not less than 5% in the legal reserve, on an annual basis until this reserve represents 20% of share capital and deducted by certain non-distributable fair value reserves. Portuguese law also prohibits the payment of dividends if, following the dividend, a company's net worth would be less than the sum of its share capital, the legal reserve and other similar reserves established by Portuguese law or by the articles of association. The category of other similar reserves includes, among other things, the portion of the revaluation reserve related to assets not yet amortized and the reserve equivalent to the book value of treasury shares.

Any dividend in excess of 40% of our distributable net income in any year may be vetoed by a majority of the holders of the A shares, voting as a class.

According to the new rules established by Article 96 of the Portuguese Securities Code (as amended by the Decree-Law 8/2007, of January 17, 2007), for one month from the publication of the registration of a share capital reduction, Portugal Telecom will not be able to distribute assets to its shareholders.

Dividends are payable from net income and free reserves (i.e., reserves other than the legal reserve). Portuguese law requires net income and free reserves to be applied against accumulated losses for the given financial year, and only thereafter may share issuance premium, be applied against

accumulated losses. The share issuance premium is the amount corresponding to the subscription price paid for a share over the par value of the share. This requirement was amended by Ministerial Order, dated February 19, 2003, so that companies listed on a stock exchange and under the supervision of the Portuguese Securities Commission are permitted to apply share issuance premium against accumulated losses after applying net income but before applying free reserves.

The following table presents dividends paid per ordinary share and A share for the years ended December 31, 2007, 2008, 2009, and 2010 and proposed to be paid for the year ended December 31, 2011. U.S. dollar amounts have been calculated using the exchange rate in effect on the date on which each dividend was paid.

The ADS depositary converts Euros into U.S. dollars and pays the net proceeds to ADS holders, minus applicable withholding tax, as described below.

• *** The dividend of A0.65 per share includes the advance of profits of A0.215 per share announced on December 15, 2011 and paid on January 4, 2012. As a result, each issued share is entitled to receive A0.435 as approved at the Annual General Meeting of Shareholders held on April 27, 2012.

The general rate of withholding income tax on dividends in Portugal is currently 21.5% for both Portuguese residents and non-residents. However, under the U.S.-Portugal income tax treaty, the withholding tax rate on dividends distributed to U.S. tax residents may be reduced, as a general rule, to 15%. In order to apply the reduced treaty rate, confirmation that each shareholder is eligible for the benefits of the treaty is required, and shareholders must complete specific forms of the Portuguese Ministry of Finance and obtain certification from the U.S. Internal Revenue Service. See ''Item 10— Additional Information—Taxation—Dividends.''

Significant Changes

As of December 31, 2011, our fully subscribed and paid share capital amounted to A26,895,375, represented by 896,512,500 shares with a nominal value of A0.03 each.

As of the date of filing of this Annual Report on Form 20-F, we do not have any shares in treasury, but we do hold an equity swap for 20,640,000 shares that we entered into under a prior share buyback program. In addition, in 2011, under the strategic partnership entered into between Portugal Telecom and Oi, Telemar Norte Leste acquired 64,557,566 of our own shares, representing 7.2% of our share capital.

ITEM 10—ADDITIONAL INFORMATION

Memorandum and Articles of Association

Organization, Register and Entry Number

Portugal Telecom, SGPS S.A., is a limited liability holding company organized under the laws of the Republic of Portugal. Portugal Telecom's taxpayer and registered number is 503 215 058.

Object and Purpose

Our object and purpose, which is described in Article 3 of our articles of association, is that of a holding company. Portugal Telecom manages ownership interests in operating companies. Portugal Telecom may, without restriction, acquire or hold quotas or shares in any company, as defined under Portuguese law, hold participations in complementary groups of companies or in European economic interest groups of companies and form or participate in any temporary or permanent association with public or private entities.

Certain Provisions with Respect to Board Members

Agreements between us and our directors must be authorized by a resolution of the Board of Directors and a favorable opinion of the Audit Committee. Our directors are not permitted to vote on resolutions relating to agreements in which they are materially interested or with respect to which they have a conflict of interest. Our directors do not have the power to vote for their compensation, which is determined by a compensation committee elected by the General Meeting. Our directors may not receive loans from Portugal Telecom, except that directors may receive one month of compensation in advance. There are no age limit requirements for the retirement of board members. No minimum shareholding is required for qualification as a member of the board.

Dividends on the Ordinary Shares and the A Shares

Ordinary shares and A shares each carry the same right to receive dividends. The holder of record of ordinary shares or A shares on the date of payment of any dividend is entitled to receive that dividend. The settlement of a trade and the transfer of record ownership of shares traded on the regulated market Euronext Lisbon takes place on the third business day after the trade. As a result, any person making a trade for the purchase of ordinary shares during the three-day period prior to the record date for a dividend payment will not be entitled to receive that dividend.

The Board of Directors has sole discretion over the proposal for dividends to be paid. Under our articles of association, we must pay dividends of at least 40% of our annual distributable net income to shareholders, subject to the ability of a two-thirds majority of the votes cast at a shareholders' meeting to decide to reduce the dividend or not to pay a dividend. Each dividend must be approved by a majority of the votes cast at a shareholders' meeting. The Board of Directors, subject to certain conditions, including the consent of our Audit Committee and the certification of the registered accountant, may also resolve the payment of interim dividends.

Under Portuguese law and the articles of association, distributable net income is net income after covering accumulated losses and setting aside 5% in the legal reserve until this reserve represents 20% of share capital. Although other reserves established under a company's articles of association are

generally deducted from that company's distributable net income, our articles of association do not provide for any other reserves. Such reserves, however, could be established by amendment of the articles of association by a two-thirds majority of the votes cast at a shareholders' meeting. As of December 31, 2011, our legal reserve was equal to approximately 25% of our share capital.

Dividends are payable from net income and free reserves (i.e., reserves other than the legal reserve). Portuguese law requires net income and free reserves to be applied against accumulated losses for the given financial year, and only thereafter may share issuance premium be applied against accumulated losses. This requirement was amended by Ministerial Order No. 160/2003, dated February 19, 2003, so that companies with shares trading on a regulated market and under the supervision of the Comissao do Mercado de Valores Mobili ˜ arios ´ (the Portuguese Securities Exchange Commission) (''CMVM'') are permitted to apply share issuance premium against accumulated losses after applying net income but before applying free reserves.

Portuguese law also prohibits the payment of dividends when a company's shareholders' equity, including the net income for the year, is less than the sum of its share capital, the legal reserve and other similar reserves established by Portuguese law or by the articles of association of the company. The payment of a dividend would also be illegal under Portuguese law if, following the payment, the company's shareholders' equity would become smaller than that sum. The categories of other similar reserves under Portuguese law include, among other things, the portion of the revaluation reserve related to assets not yet amortized and the reserve equivalent to the book value of treasury shares.

Voting Rights of the Ordinary Shares and the A Shares

As a general rule, matters are decided at a shareholders' meeting by a simple majority of votes. However, resolutions for the amendment of the articles of association, reorganization, dissolution, or merger of Portugal Telecom and certain other matters mandated by Portuguese law require the approval of two-thirds of the votes cast at a shareholders' meeting. A quorum of not less than one-third of the share capital entitled to vote must be present or represented. If the quorum requirement is not met at the first meeting, then matters may be approved on a later day at a second call of such meeting by (1) a two-thirds majority of the votes cast at the meeting (with no quorum requirements) or (2) a simple majority of the votes cast if at least one-half of the share capital is present or represented.

As of December 31, 2011, the Board of Directors consisted of 24 directors. Members of the Board of Directors are elected for a three-year period and may be re-elected on one or more occasions. The current Board of Directors was elected at the annual general shareholders' meeting on March 27, 2009, and although its term expired on December 31, 2011, pursuant to Portuguese law, the members of the Board of Directors remain in office until new members are elected, which will occur at the annual general shareholders' meeting in early 2012. The directors are elected by a majority of the votes cast at the annual shareholders' meeting. In addition, a minority of shareholders representing at least 10% of share capital has the right to elect a director to substitute for the director previously elected by the fewest number of votes, provided that such minority has voted against the proposal for the election of directors.

Under the Portuguese Companies Code, all rights attached to treasury stock are suspended, including voting rights. As a result, treasury stock is neither counted for the purpose of calculating any minimum quorum nor for determining a majority of votes cast. The purchase by Portugal Telecom of its own shares generally must be approved by its shareholders in accordance with our articles of association and the Portuguese Companies Code. Under Portuguese law, a Portuguese company may not, except under certain limited circumstances (such as the repurchase of its own shares for the purpose of reducing share capital), purchase more than 10% of its nominal share capital as treasury stock.

Under our articles of association, the voting rights exercised by a single shareholder are limited to a maximum of 10% of our share capital. As a result, no single shareholder can exercise voting rights in his own name or on behalf of other shareholders representing more than 10% of our share capital. Holders of ADSs are treated as holders of the ordinary shares represented by the ADSs for purposes of determining the applicability of the 10% limitation on voting rights. Voting instructions of an individual ADS holder will not be accepted by Portugal Telecom as votes of the ordinary shares to the extent that such votes, together with any votes cast by such ADS holder as holder of ordinary shares, exceed 10% of the voting power of Portugal Telecom.

Pre-Emptive Rights

Upon the issuance of additional ordinary shares by Portugal Telecom for cash, all holders of ordinary shares and A shares have a right to subscribe proportionately for such shares. Upon the issuance of additional A shares by Portugal Telecom, holders of A shares have a right to subscribe proportionately for those shares, and to the extent that all such shares are not sold, holders of ordinary shares may subscribe proportionately for the remainder of the shares. The pre-emptive rights of shareholders to subscribe for shares are freely transferable.

Liquidation Rights

The ordinary shares and A shares have pro rata rights to share in our assets upon our liquidation.

Changes in Rights of Shareholders

The rights of holders of Portugal Telecom shares may only be changed by a shareholder resolution amending the articles of association. Resolutions for the amendment of the articles of association require the approval of two-thirds of votes cast at a shareholders' meeting. A quorum of not less than one-third of the share capital entitled to vote must be present or represented. If the quorum requirement is not met at the initial meeting, then those matters may be approved at a later date at a second call of that meeting by a two-thirds majority of the votes cast at the meeting (with no quorum requirements) or a simple majority of the votes cast if at least one-half of the share capital is present or represented.

Shareholders' Meetings

Shareholders' meetings may be held at our registered office or, when the registered office does not have satisfactory conditions for the meeting, at another location within the Portuguese territory. Shareholders' meetings are called by publication of a notice on the Ministry of Justice's website (http://publicacoes.mj.pt), the website of the CMVM (www.cmvm.pt), our website (www.telecom.pt) and, although not required by law, in a daily newspaper with national distribution (Diario de Not ´ ´ıcias). An annual shareholders' meeting must be held before the end of May and must be convened with advance notice of at least 21 days. At the annual shareholders' meeting, the annual accounts, including a report on our activities during the previous year and any proposal for the payment of dividends, are presented to the shareholders for approval. Meetings may also be called upon the request of the Board of Directors, the Audit Committee or shareholders holding at least 2% of share capital.

In accordance with the Portuguese Securities Code, as amended in 2010, only shareholders who, at the record date (corresponding to 00:00 (GMT) of the fifth trading day prior to the date of the general meeting), hold shares that, under the law and the articles of association, entitle them to exercise at least one vote shall have the right to attend and vote at a shareholders' meeting. The exercise of participation and voting rights at a shareholders' meeting shall not be hindered by any transfer of shares at a time following the record date, nor does it depend on the blocking of such shares between the record date and the date of the shareholders' meeting.

Shareholders may attend a shareholders' meeting in person or by proxy or to vote by courier or electronic means, in accordance with the procedures set out in each meeting's notice. Shareholders may appoint different representatives as to shares held in different securities accounts.

Furthermore, any shareholder who, as a professional, holds shares in his own name but on behalf of his clients may vote in different directions with his shares, provided that all procedures therefor set out in the meeting's notice are complied with.

Shareholders' meetings are presided over by a chairman appointed by the shareholders.

Transfer of Ordinary Shares, Limitations on Shareholdings

There are no restrictions on the transferability of our ordinary shares, other than certain limitations on ownership. Under the Portuguese Securities Code, any person making a purchase or sale of shares that results in that person either reaching, exceeding or holding less than 2%, 5%, 10%, 15%, 20%, 25%, 33.3%, 50%, 66.6% or 90% of our voting rights must notify us and the CMVM within four trading days as from the date on which the fact takes place or is acknowledged by such person. Holdings must be calculated to take into account all outstanding shares with voting rights, regardless of the number of voting rights that may be suspended at the time.

In addition, following the entry into force of CMVM Regulation No. 5/2010, long financial positions in Portuguese listed companies shall also be notified to the relevant company and the CMVM and disclosed to the market. The disclosure duty is triggered whenever a long position reaches or exceeds 2%, 5%, 10%, 15%, 20%, 25%, one third, 40%, 45%, one half, 55%, 60%, two thirds, 70%, 75%, 80%, 85% and 90% of the share capital and also when such position is reduced below any of these thresholds. Under such Regulation, the contracts or financial instruments with an economic effect similar to the holding of shares that do not autonomously give rise to the attribution of voting rights, held directly or by a third party in any of the situations set out in article 20 (1) of the Portuguese Securities Code, such as CFD's and cash-settled swaps, options, futures and forwards, are considered as long financial positions.

Our articles of association contain limitations on ownership, as well as mechanisms that may prevent a change of control of Portugal Telecom. The articles of association provide that no shareholder performing, directly or indirectly, an activity which competes with any of our activities may hold or control ordinary shares representing in the aggregate more than 10% of our share capital, without authorization of a shareholders' meeting. An entity will be deemed to be performing an activity which competes with our activities if they, a company of which they own at least 10% of the share capital or a company that owns at least 10% of the share capital of that entity (1) offers, in or outside of Portugal, ''public telecommunications services'' (except ''audiotext services'') or ''network services,'' as such terms are defined under Portuguese law or (2) engages in any other activity of the same type and nature as that being performed by entities in which Portugal Telecom holds more than 50% of the share capital or voting power or has the power to appoint more than 50% of the governing body or of the supervisory body. The Bank of New York Mellon, as ADS depositary, and its nominees are excluded from this requirement.

If any such shareholder holds or controls ordinary shares exceeding 10% of our share capital, our shareholders may decide at a shareholders' meeting to require the cancellation of the ordinary shares held exceeding such 10% limit. In such case, we must compensate the shareholder for the lesser of the nominal value of the canceled ordinary shares or their market value. However, within five days of receipt of notice of such a decision by the shareholders' meeting, a shareholder may request the permission of the Board of Directors to reduce the number of ordinary shares held to 10% or less of our share capital by sale or other form of transfer of the excess ordinary shares within 30 days, thus suspending the shares cancellation process. By making such request, such shareholder renounces,

pending the conclusion of such sale or transfer, all voting and pre-emptive subscription rights connected to the excess ordinary shares.

Holders of ADSs will be treated as holders of the ordinary shares represented by the ADSs under these provisions.

There are no restrictions under Portuguese law with regard to the percentage of shares that a non-Portuguese resident may own in Portugal Telecom.

Change of Control Provisions

Our articles of association contain limitations on ownership, as well as mechanisms that may prevent a change of control of Portugal Telecom. Under the articles of association, the voting rights exercised by a single shareholder are limited to a maximum of 10% of our share capital. As a result, no single shareholder can exercise voting rights, in his own name or on behalf of other shareholders, representing more than 10% of our share capital. The articles of association also provide that no shareholder performing, directly or indirectly, an activity which competes with any of our activities may hold or control ordinary shares representing in the aggregate more than 10% of our share capital, without shareholder authorization. See ''—Transfer of Ordinary Shares, Limitations on Shareholdings.''

Disclosure of Shareholdings and Shareholders' Agreements

Our articles of association do not require shareholders to disclose their shareholdings. Shareholders are required under our articles of association to provide information on shareholders' agreements.

Changes in Capital

With the approval of the Audit Committee, the Board of Directors may increase the share capital of Portugal Telecom on one or more occasions, up to a maximum of A15,000,000. Certain terms of a share capital increase, such as the maximum amount of the share capital increase, the class of shares to be issued and whether any limitations will be imposed on the subscription rights of shareholders, must be approved by the shareholders at a general meeting.

Corporate Governance

Portuguese Legal Framework

The principal source of corporate governance standards in Portugal is the Portuguese Companies Code, which was enacted in 1986 and codified European Union directives on commercial law. The Portuguese Companies Code was subject to three major amendments in 2006, 2007 and 2009. A revision on March 29, 2006 mainly related to corporate governance matters. On January 17, 2007, a second revision covered issues such as share capital reductions and disclosure of financial information. Finally, in 2009, a recent European Union directive on the annual accounts and consolidated accounts of certain types of companies was implemented into the Portuguese legal framework, and as a result, measures have been taken in order to modernize company law, improve EU-wide comparability and public confidence in financial statements and reports, increase transparency in transactions with related parties and off-balance sheet arrangements and improve disclosure about corporate governance practices applied in a company. Moreover, Portuguese rules on mergers and spin-offs were significantly simplified.

The Portuguese Companies Code is legally binding on any company with a registered office in Portugal. The Portuguese Companies Code establishes corporate governance standards with respect to the following:

• Shareholder pre-emptive rights, which are intended to protect shareholders and holders of securities convertible into shares against dilution;
• Share capital formation and capital increases, including the mandatory verification by independent auditors of contributions in kind;
• Dividends, which are subject to mandatory minimum distributions of 50%, except in limited circumstances, including if a lower percentage is set forth in the articles of association (as is the case for Portugal Telecom);
• Shareholders' meetings, including minimum notice requirements, minority rights, voting by courier, and requirements that shareholders elect the chairman and other officials of the meeting who must be independent members (in the case of major companies and issuers of securities traded on a regulated market, like Portugal Telecom) and are empowered to convene and conduct the meetings;
• Annual reports of management to the shareholders' meeting;
• Shareholder access to information, including the right to request information in general meetings, and minority rights to request information regarding the company's performance;
• Shareholder rights to, in certain circumstances, request the judicial declaration of annulment or voiding of decisions taken at a shareholders' meeting and the suspension of an illegal resolution, as well as to request to the chairman of the board of the shareholders' meeting to suspend a meeting in progress;
• Management and supervisory structure, including three models of corporate governance from which companies may choose, as follows:
  • a two-tier model, with a management body (the so-called executive management board) and a supervisory body (the so-called supervisory board, which must have a chairman, who may not be the chairman of the executive management board, and a committee for financial matters);
  • a one-tier model, with the board of directors as a management body (which, by contrast to the management body in a two-tier model, may delegate day-to-day management to an executive committee, and its chairman may also be the chairman of the executive committee) and the statutory audit board as a supervisory body; and
  • an altered ''Anglo-Saxon'' model, in which the board of directors (the management body) includes an audit committee, which is a corporate body composed of non-executive directors with supervisory functions. In this model, the board may also delegate the day-to-day management to an executive committee, and its chairman may also be the chairman of the executive committee;
• An audit function, which is conducted by a statutory auditor who is elected by shareholders based on a proposal of the supervisory body (since the March 2006 amendment to the Portuguese Companies Code, the statutory auditing function—carried out by the statutory auditor—has been separated from the supervision of management—carried out by the supervisory body);
• Appointment of members of the management and supervisory bodies at a shareholders' meeting and appointment of the statutory auditor at a shareholders' meeting, as mentioned above, based on a proposal of the supervisory body;
• Strengthening of the supervisory functions of the supervisory body's membership (it being mandatory for the aforementioned committee for financial matters, the statutory auditor board and the audit committee to be composed of a majority of independent members among whom there must be an expert, as defined in the law) and broadening the scope of the supervisory powers (by adding powers on matters such as whistleblowing systems, oversight of the work and independence of the statutory auditor, and making proposals on the selection and confirmation of the statutory auditor);
• Conflicts of interest, which are highly regulated, including a requirement that board members make their share transactions and significant shareholdings public and that they recuse themselves from participating and voting in any matters in which they have a personal interest;
• Fiduciary duties of board members to shareholders and the company; and
• Compensation of members of the board of directors, which is established by the general shareholders' meeting or by a compensation committee appointed by a shareholders' meeting.

The Portuguese Securities Code and related rules complement the corporate governance provisions set forth in the Portuguese Companies Code, notably by:

• requiring immediate disclosure of material information;
• requiring disclosure of qualifying holdings and long financial positions, as well as certain periodic information, including financial statements and an annual corporate governance report and measures to prevent market abuse (such as notifying the CMVM of transactions carried out by persons exercising management functions and related persons);
• setting out additional rules concerning shareholders' rights and participation and voting rights in shareholders' meetings; and
• establishing criminal and administrative sanctions for the breach of the material information regime, in particular providing for market abuse crimes (insider trading or abuse and market manipulation).

In addition to these Codes, Portugal Telecom, as an issuer of securities traded on the regulated market Euronext Lisbon, is subject to Regulations and Recommendations issued by the CMVM, including the Regulation on Corporate Governance for Listed Companies, or Regulation No. 1/2010, and the CMVM Corporate Governance Code (the ''Corporate Governance Code''), as amended and applicable beginning with the 2010 financial year. Regulation No. 1/2010 primarily addresses the mandatory content of the annual corporate governance report of a listed company's website, and disclosure of equity compensation plans. The Corporate Governance Code governs matters involving the general shareholders meeting, the exercise of voting rights, quorums for meetings and resolutions, disclosure of information concerning general shareholders' meetings, anti-takeover provisions, the structure and powers of the management and supervisory corporate bodies, independence and incompatibility criteria applicable to the members of such corporate bodies, whistleblowing policies, remuneration of the members of corporate bodies and other officers, rules concerning the delegation of powers to executive directors or committees, specific duties of the supervisory corporate body, committees with specific duties such as the follow-up of corporate governance issues and the selection and evaluation of directors, and matters concerning the investor relations department and transactions with significant shareholders.

Regulation No. 1/2010 has introduced two major changes: (1) it allows issuers of shares admitted to trading on a regulated market to adopt a Corporate Governance Code other than the one issued by the CMVM, provided that such Code complies with the conditions described in the Regulation (a preliminary draft of governance code prepared by the Portuguese Corporate Governance Institute (Instituto Portuguˆes de Corporate Governance), which may eventually become an alternative to the Corporate Governance Code, is currently under discussion) and (2) it requires listed companies to disclose the compensation paid to each of the members of their corporate bodies and requires further detail concerning the information to be disclosed by listed companies on the compensation of the members of their management and supervisory bodies.

The Corporate Governance Code sets forth new recommendations primarily regarding the following issues: internal control and risk management internal systems; selection and remuneration of the management body's members; independence of the compensation committee; rotation, duties and independence of the external auditor; and transactions with significant shareholders.

In 2007, our shareholders approved a proposal of the Board of Directors adopting a new corporate governance model, under the ''Anglo-Saxon'' model described above, and introducing the required amendments into our articles of association. Our decision to adopt the new ''Anglo-Saxon'' model took into account, among other things, the fact that we have securities traded on the New York Stock Exchange (''NYSE''), where this structure is mandatory for U.S. domestic companies, as well as the fact that Portugal Telecom already had an audit committee. Following the adoption of the ''Anglo-Saxon'' model, our corporate bodies consist of the General Meeting of Shareholders, the Board of Directors, which includes an Audit Committee, and a Statutory Auditor.

Summary of Significant Differences Between Portuguese Corporate Governance Practices and the New York Stock Exchange's Corporate Governance Standards

The following paragraphs provide a brief general summary of significant differences between the corporate governance practices followed by Portuguese companies, such as Portugal Telecom, and those required for domestic companies under NYSE listing standards.

Composition of Board of Directors and Independence

The NYSE listing standards provide that the board of directors of a U.S. listed company must consist of a majority of independent directors and that certain committees must consist solely of independent directors. A director qualifies as independent only if the board affirmatively determines that the director has no material relationship with the company, either directly or indirectly. In addition, the listing standards enumerate a number of relationships that preclude independence. The listing standards do not specifically deal with the avoidance of conflicts of interest and related party transactions. These matters are typically governed by the laws of the state in which the listed company is incorporated.

Portuguese law does not require all members of management or the board of directors of a Portuguese company to be independent. However, under the Corporate Governance Code approved by the CMVM, a listed company is required to disclose in its corporate governance annual report whether its management includes an adequate number of independent members corresponding to at least one-fourth of the entire board. Moreover, Portuguese law does provide that the majority of the members of the audit committee must be independent according to the criteria established in the Portuguese Companies Code, that all the members of the audit committee fulfill the legal requirements concerning incompatibilities and that at least one of the independent members satisfies legal requirements concerning expertise in auditing or accounting. The Corporate Governance Codes also provides that the chairman of the audit committee should be independent. These principles are designed to strengthen the supervision of the audit function and to avoid conflicts of interest. Members of the audit committee will be deemed independent if they are neither associated with any specific interest groups in the company nor under any influence that might affect the neutrality of their analysis or decisions. In particular, Portuguese law will not deem independent any holder, or any person acting on behalf or for the account of, a holder of a qualifying holding equal to or higher than 2% of the company's share capital, nor anyone being reelected for more than two terms of office whether subsequent or not.

The Audit Committee elected at the General Meeting of Shareholders on March 27, 2009, and reelected at the General Meeting of Shareholders held on April 27, 2012, complied with the independence requirements under Portuguese law, and each member of the Audit Committee also meets the independence requirements under Rule 10A-3 under the U.S. Securities Exchange Act of 1934, as amended (the ''Exchange Act'').

Meetings of Non-Management Directors

The NYSE listing standards provide that the non-management directors of each U.S. listed company must meet at regularly scheduled executive sessions without management in order to empower them to serve as a more effective check on management. There is no similar requirement or recommendation under Portuguese law.

Committees of the Board of Directors

The NYSE listing standards require that a U.S. listed company must have a nominating/corporate governance committee and a compensation committee, and that all listed companies, including non-U.S. listed companies, must have an audit committee that satisfies the requirements of the Exchange Act. U.S. listed companies must have an audit committee that fulfils additional NYSE-imposed requirements. The NYSE listing standards require each of these committees to consist solely of independent directors and to have a written charter that addresses certain matters specified in the listing standards. The NYSE's detailed requirements for the content of audit committee charters do not apply to non-U.S. listed companies.

Portuguese law requires companies adopting a two-tier or an ''Anglo-Saxon'' corporate governance model (as described under ''—Portuguese Legal Framework'' above) to have, respectively, a committee for financial matters within the supervisory body or an audit committee within the Board of Directors, in each case satisfying certain requirements as to the committee's minimum powers, independence and expertise. Moreover, in each model, the Portuguese Companies Code permits the creation of a compensation committee, within the supervisory board in the two-tier model, or appointed by a general meeting of shareholders, in the case of the one-tier or ''Anglo-Saxon'' models.

Under the CMVM's Corporate Governance Code, the board of directors, in the one-tier or ''Anglo-Saxon'' models, or the supervisory body, in the two-tier model, should create committees, including corporate governance and evaluation committees, in order to ensure that a competent and independent evaluation is made as to the performance of executive directors and other members of the board of directors. The Corporate Governance Code further recommends that listed companies, in addition to those committees, create a nominating committee in order to ensure a timely identification of potential candidates with the high profile required for the performance of a director's duties.

Audit Committee

Portugal Telecom established an Audit Committee in December 2003, consisting of independent members of its Board of Directors. The Audit Committee operated as a committee of the Board of Directors with delegated powers in the following matters: (1) supervising the quality and integrity of the financial information contained in our financial statements, (2) evaluating the qualification and independence of our external auditors, (3) evaluating the quality, integrity and efficiency of our internal control systems, (4) evaluating the execution of functions performed by our external auditors and the corporate internal auditing office and (5) evaluating the compliance with legal and regulatory requirements, as well as those recommendations and guidelines issued by competent authorities.

In 2007, Portugal Telecom redesignated the Audit Committee as Portugal Telecom's Supervisory Corporate Body. According to the articles of association, the members of the Audit Committee must comply with the requirements on incompatibilities, independence and expertise arising from the Portuguese law and regulations, as well as other relevant market rules, including those in force in the jurisdictions where Portugal Telecom has securities admitted to trading. As a supervisory body, the Audit Committee has the powers to, in addition to all other powers established by law or our bylaws,

• approve and disclose an annual report on their supervisory activity, expressly mentioning any constraints faced;
• approve an annual action plan contemplating, among others, the measures required for compliance with its duties in the following year;
• inform and discuss with the Board of Directors and the Executive Committee, within their respective powers and duties, any situations identified in the exercise of their powers and duties;
• discuss and issue its prior opinion within the scale of its powers and whenever it deems it necessary to the Executive Committee and the external auditors on any reports, documentation or information to be disclosed to the competent authorities;
• adopt procedures to ensure compliance with the legal and regulatory provisions that are applicable to us;
• evaluate the accuracy and supervise the quality and integrity of our financial statements and generally supervise the quality and integrity of the financial information contained in our financial statements;
• analyze and give its opinion on accounting and auditing matters, as well as the impact on our financial statements of changes to accounting rules applicable to us and our policies;
• establish and monitor the procedures relating to the preparation and auditing of our financial statements by the statutory auditor and the external auditors, as well as supervise and review internal procedures on accounting and auditing practices;
• propose the appointment of the Statutory Auditor to the General Meeting of Shareholders;
• supervise the independence of the Statutory Auditor, particularly with respect to the rendering of additional services;
• order the appointment, hiring, confirmation or termination of duties and determine the remuneration of our external auditors, in addition to being exclusively responsible for their supervision and evaluation of their qualifications and independence, and approve the audit and/or other services to be rendered by such external auditors or by persons associated to them. The external auditors must report and be subject to the direct and exclusive supervision of the audit committee, which each year shall obtain from and review with the external auditors an external audit report;
• settle any differences between the Executive Committee and our external auditors with respect to financial information to be included in the financial statements to be reported to competent authorities, or with respect to the audit report process;
• evaluate the quality, integrity and efficiency of our risk management system, internal control system and internal audit system, including an annual review of their adequacy and efficiency, and generally supervise our internal audit and internal control systems;
• receive reports of irregularities, claims and complaints submitted by shareholders, employees or others, and implement procedures designed to receive, register and process them when related to accounting and auditing matters, and create internal control procedures on such matters;
• verify whether the company's governance report disclosed each year includes all legally required data, as well as to express its agreement or disagreement as to the annual management report and accounts for the financial year; and
• inform, discuss and analyze with the Board of Directors and the Executive Committee and advise, whenever it deems necessary, on situations resulting from the exercise of its powers.

As a result, the Audit Committee monitors our compliance with laws, regulations, recommendations and guidelines issued by the U.S. Securities and Exchange Commission (''SEC''), NYSE, CMVM, and the Euronext Lisbon and defines and implements policies to ensure our compliance with these laws, regulations, recommendations and guidelines.

Joao Manuel de Mello Franco (Chairman), Jos ˜ e Guilherme Xavier de Basto and M ´ ario Jo ´ ao de ˜ Matos Gomes were elected as members of the Audit Committee for the 2009-2011 term of office at the General Meeting of Shareholders held on March 27, 2009 and were reelected for the 2012-2014 term of office at the General Meeting of Shareholders held on April 27, 2012.

Additionally, the new corporate governance structure includes a Statutory Auditor who is not one of the members of the Audit Committee, as required by the Decree-Law No. 76-A/2006 of March 27, 2006, which amended the Portuguese Companies Code. The current Statutory Auditor was appointed at the General Meeting of Shareholders held on March 27, 2009 and was reappointed at the General Meeting of Shareholders held on April 27, 2012. P. Matos Silva, Garcia Jr., P. Caiado & Associados SROC, Lda., represented by Pedro Joao Reis de Matos Silva, was elected as the Effective Statutory ˜ Auditor, and no Alternate Statutory Auditor was appointed, as permitted by law.

The Compensation Committee is elected at the General Meeting of Shareholders and is in charge of (1) establishing the compensation for members of our corporate bodies and (2) following up and evaluating the performance of our directors with reference to our business goals (without prejudice to the powers of the Evaluation Committee described below). The current members of the Compensation Committee are: Alvaro Pinto Correia (Chairman), Francisco ´ Esteves de Carvalho and Francisco Jose Queiroz de Barros Lacerda. No member of the Compensation ´ Committee may be a member of any corporate body or committee within the Company, and no member of the Compensation Committee may have any family connection to any member of the Board of Directors by way of marriage, kin or affinity in a direct line and up to and including the third degree.

Disclosure

The NYSE listing standards require U.S. listed companies to adopt, and post on their websites, a set of corporate governance guidelines. The guidelines must address: director qualification standards, director responsibilities, director access to management and, as necessary and appropriate, independent advisors, director compensation, director orientation and continuing education, management succession, and an annual performance evaluation of the board of directors. In addition, the CEO of a U.S. listed company must certify to the NYSE annually that he or she is not aware of any violations by the company of the NYSE's corporate governance listing standards. The certification must be disclosed in the company's annual report to shareholders.

Under CMVM Regulation No. 1/2010, the executive management and board of directors are required to disclose either that they are in compliance with the recommendations set forth by the CMVM or which recommendations they have not followed and provide reasons therefor. This disclosure is included in our Corporate Governance Report, which is attached as an appendix to our Portuguese annual report and to the English translation of that report.

Code of Business Conduct and Ethics

The NYSE listing standards require each U.S. listed company to adopt, and post on its website, a code of business conduct and ethics for its directors, officers and employees and promptly disclose any waivers of the code for directors or executive officers. There is no similar requirement or recommendation under Portuguese law. However, under the Exchange Act rules and regulations, all foreign private issuers, such as Portugal Telecom, must disclose in their annual reports on Form 20-F whether they have adopted a code of ethics that applies to the principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions or, if they have not adopted such a code, why they have not done so. In addition, they must either file a copy of the code with the U.S. Securities Exchange Commission as an exhibit to their annual reports; post the text of the code on their websites and disclose in their annual reports their Internet addresses and the fact that they have posted such a code on their websites; or undertake in their annual reports to provide a copy upon request to any person without charge. There is significant, though not complete, overlap between the code of ethics required by the NYSE listing standards and the code of ethics required by the Exchange Act rules.

Portugal Telecom has a code of ethics that complies with Exchange Act requirements and approved a separate code of ethics for financial officers in December 2004. See ''Item 16B—Code of Ethics.''

Shareholder Approval of Equity Compensation Plans and Pension Plans

The NYSE listing standards provide that shareholders must be given the opportunity to vote on all equity compensation plans and material revisions thereto, with limited exemptions for employment inducement awards, certain grants, plans and amendments in the context of mergers and acquisitions, and qualified plans, parallel excess plans and Section 423 of the U.S. Internal Revenue Code plans.

Portuguese law also establishes that equity compensation plans shall be approved by shareholders. The Corporate Governance Code issued by the CMVM provides that the proposal submitted to the shareholders' meeting concerning the approval of plans for allotment of shares and/or regarding options for the acquisition of shares for members of the management body, the supervisory body and/or persons exercising management functions, as defined under Article 248-B, paragraph 3 of the Portuguese Securities Code, or any pension plans for these persons, include all details necessary for a correct evaluation of the plans. The full text of the plan's regulations or general conditions, as applicable, must be attached to the proposal. In addition, CMVM Regulation No. 1/2010 on corporate governance establishes a duty of listed companies to inform the CMVM of the approval of stock option plans within seven business days from the respective approval.

Other Committees and Functions

• assisting the Board of Directors in the performance of its duties and powers regarding the selection of directors (upon the initiative of the Chairman of the Board of Directors or of shareholders having the capacity to submit lists to voting) and the appointment and substitution of directors that compose special committees of Portugal Telecom's Board of Directors, as well as the directors composing the Executive Committee, in the latter case upon a proposal of the Chief Executive Officer; and
• advising the Executive Committee in the matter of selection and relevant criteria for determination of the remuneration of the members of management bodies of Portugal Telecom's most significant subsidiaries.

As of December 31, 2011, the members of the evaluation committee were Henrique Granadeiro (Chairman of the Evaluation Committee), Zeinal Bava, Joao de Mello Franco, Francisco Pereira ˜ Soares, Joaquim Goes, Rafael Mora Funes and Jorge Tome (who resigned from his duties at Portugal ´ Telecom on February 29, 2012).

Risk Management System

Our Internal Control and Risk Management team, with hierarchical reporting to the Chief Executive Officer and Chief Financial Officer and functional reporting to the Audit Committee, is in charge of assessing our risk management procedures and optimizing these procedures by adopting industry best practices and conforming to the COSO method for internal control matters. This team enables us to identify and prioritize critical risks to our company, and thus develop suitable risk management strategies.

Material Contracts

Oi and Contax Agreements

On January 26, 2011, we announced that we had entered into a series of agreements with Oi, Brazil's largest telecommunications group, to acquire a significant interest in that company. In connection with our agreements to establish a strategic partnership with Oi, we also agreed to merge Dedic and GPTI, our subsidiaries that provide call center and IT/IS services in Brazil, with Contax. On March 28, 2011, we completed the acquisition of a direct and indirect interests of 25.3% in Oi and 14.1% in Contax, for total consideration of R\$8,437 million (A3,728 million). In connection with the transactions, we obtained direct and indirect interests of 25.6% in Telemar Participa¸coes and 42.0% in ˜ CTX Participa¸coes, the controlling shareholders of Oi and Contax, respectively. ˜

The final step of the acquisition of Contax consisted of the acquisition of Dedic/GPTI (our existing Brazilian business process outsourcing provider) by Contax and was completed on July 1, 2011, as the boards of directors and shareholders of Dedic, CTX and Contax approved the following transactions: (1) the exchange of Portugal Telecom's investment in Dedic/GPTI for a 7.6% interest in Contax, (2) the exchange of a 1.3% interest in Contax held by Portugal Telecom for an additional 3.7% interest in CTX and (3) the disposition by Portugal Telecom to CTX of a 2.0% interest in Contax for a total amount of

R\$49.7 million (A22 million). As a result of these operations, our direct and indirect interests in CTX and Contax were increased from 42.0% to 44.4% and from 14.1% to 19.5%, respectively, and Dedic/ GPTI became a wholly owned subsidiary of Contax.

In connection with the establishment of our strategic partnerships with Oi and Contax, we also entered into shareholders' agreements with the controlling shareholders of Oi and Contax, pursuant to which we have obtained significant corporate governance rights. These agreements are described under ''Item 4—Information on the Company—Our Businesses—Brazilian Operations (Oi)—Strategic Partnership with Oi'' and ''Item 4—Information on the Company—Our Businesses—Other International Operations— Other Brazilian Operations—Strategic Partnership with Contax.''

Vivo Agreement

On July 28, 2010, we signed an agreement with Telefonica for the acquisition by Telef ´ onica of the ´ 50% of the capital stock of Brasilcel we owned. Brasilcel owned approximately 60% of the total share capital of Vivo. The acquisition price of such capital stock was A7,500 million, A4,500 million of which was paid at the closing of the transaction on September 27, 2010 and A1,000 million of which was paid on December 30, 2010, with the remaining A2,000 million due on October 31, 2011 (though we may request that this final payment be made on July 29, 2011, in which case this final payment, and correspondingly, the total price of the acquisition, would be reduced by A25 million). The agreement also provided for certain other commercial arrangements between Telefonica and Portugal Telecom ´ which were subsequently rendered inapplicable. Upon closing of the transaction, the respective subscription and shareholders agreements entered into by Telefonica and Portugal Telecom in 2002 ´ relating to their joint venture in Brazil were terminated.

UOL Agreement

On December 29, 2010, we reached an agreement for the sale of our 28.78% interest in UOL, Brazil's largest internet provider by revenue to a Brazilian businessman. The total consideration for the sale was R\$356 million (A 161 million as of December 31, 2010). The transaction closed on January 27, 2011.

Transfer of Regulated Pension Plans

On December 2, 2010, we reached an agreement with the Portuguese Government for the transfer to Caixa Geral de Aposenta¸coes, the Portuguese institution responsible for managing post retirement ˜ benefits for civil servants, of the pension liabilities that were guaranteed by PT Comunica¸coes relating ˜ to a portion of its active and former employees, as well as the pension fund assets associated with those liabilities. This agreement is described in ''Item 5—Operating and Financial Review and Prospects— Liquidity and Capital Resources—Post Retirement Benefits.'' The agreement is reflected in a decree-law of the Portuguese Government rather than in a contract.

Wireline Pricing Convention

Prices in our wireline business are set pursuant to a pricing convention entered into with ANACOM and DGCC in December 2002 (the ''Universal Service Convention''). A copy of this agreement is filed as an exhibit to this Annual Report on Form 20-F. Under the Universal Service Convention, any price changes must be approved by ANACOM. The Universal Service Convention specifically regulates fixed telephone services (excluding ISDN), public telephone services and information services using a system of gradual cost adjustments, price caps and maximum ratios. The price of public telephone services is regulated by the use of a maximum ratio in relation to subscriber prices. In addition, the Universal Service Convention includes provisions to make prices more accessible, such as a pricing plan for low-use customers, a discount for retired and fixed-income

individuals and assistance for customers with special needs. Although the Universal Service Convention expired in 2003, ANACOM continues to review and approve price increases based on the characteristics of the relevant market.

Indebtedness

On November 7, 2006, we entered into an Amended and Restated Programme Agreement, a Fifth Supplemental Trust Deed, and Amended and Restated Agency Agreement and other documents relating to our Global Medium Term Note Program, increasing the size of the program to A7.5 billion. The issuer under the program is our subsidiary Portugal Telecom International Finance B.V., and the program benefits from Keep Well Agreements from Portugal Telecom and PT Comunica¸coes, S.A. ˜ Copies of these documents are filed as Exhibits 2.2, 2.3, 2.4, 2.5 and 2.6 to this Annual Report on Form 20-F.

On August 7, 2008, we issued A50 million in floating rate notes under our global medium term note program at a floating rate three-month European Interbank Offered Rate (''Euribor'') plus 1.50%, maturing in 2013.

In 2009, we undertook the following issuances under our global medium term note program:

• B300 million reopening. In February 2009, we issued an additional A300 million under the series of notes due 2012 that were originally issued in 2005.
• B1 billion Eurobond. In April 2009, we issued a A 1 billion Eurobond, with a maturity of four years at an interest rate of 6.0% per annum. We used the proceeds to finance our Pay-TV strategy and to provide additional financial flexibility by reducing our use of commercial paper and standby lines.
• B250 million fixed rate notes. In July 2009, we issued A250 million fixed rate notes due 2017 through a private placement.
• B750 million Eurobond. In November 2009, we issued A750.0 million in fixed rate notes under our global medium term note program at an interest rate of 5.0%, maturing in 2019.

In 2011, our subsidiary Portugal Telecom International Finance B.V. issued A600 million in fixed rate notes at an interest rate of 5.625%, maturing in 2016.

On March 25, 2011, we announced that we had entered into a new A 900 million revolving credit facility maturing in 2014. The facility was increased to A1,050 million on April 12, 2011 and to A 1,200 million on April 13, 2011.

On May 31, 2011, we announced that that the exchange price and the threshold amount of Portugal Telecom International Finance B.V.'s A750,000,000 4.125% Exchangeable Bonds due in 2014 and exchangeable into ordinary shares of PT (the ''Bonds'') were adjusted in accordance with Condition 6.2(c)(i) of the Bonds and is disclosed in its respective release.

On June 3, 2011, S&P announced its review of the credit rating attributed to us, downgrading PT long-term rating from BBB to BBB, with negative outlook, and the short-term rating from A-2 to A-3.

On June 7, 2011, Moody's announced its review of the credit rating attributed to us, downgrading PT long-term rating from Baa2 to Baa3.

On July 29, 2011, Moody's announced that it confirmed the Baa3 Issuer Rating of PT and the ratings of its fully owned subsidiary PT International Finance B.V. (PTIF) with negative outlook, concluding the rating review process initiated on June 7, 2011.

On December 23, 2011, Moody's announced its review of the credit rating attributed to PT and the ratings of its fully owned subsidiary PT International Finance B.V., downgrading the long-term rating from Baa3 to Ba1.

On April 13, 2012, Moody's announced its review of the credit ratings of Portugal Telecom and of our wholly owned subsidiary PT International Finance B.V., through which we have incurred certain of our indebtedness, downgrading the long-term ratings from Ba1 to Ba2, with negative outlook.

See ''Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources— Indebtedness—Debt Instruments and Repayment and Refinancing of Indebtedness'' for more information about this indebtedness.

In the last three years, we have also incurred other indebtedness described in ''Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Indebtedness—Debt Instruments and Repayment and Refinancing of Indebtedness,'' which subsection is incorporated here by reference.

Exchange Controls

None of the member countries of the European Union or the EU that have adopted the Euro, including Portugal, has imposed foreign exchange controls on the Euro. There are currently no foreign exchange control restrictions in Portugal on remittances of dividends on our ordinary shares or on the conduct of our operations.

Taxation

The following is a summary of the material Portuguese and U.S. federal income tax consequences of the acquisition, ownership and disposition of ordinary shares or ADSs by U.S. Holders, as defined below. This discussion does not address all aspects of Portuguese and U.S. federal income taxation that may be relevant to a particular holder based on such holder's particular circumstances. For example, with respect to U.S. Holders, the following discussion does not address the U.S. federal income tax consequences to a U.S. Holder (i) which owns or has owned (directly, indirectly or through attribution) 10% or more of Portugal Telecom's voting power; (ii) which is a dealer in securities, an insurance company, a bank, a tax-exempt organization, or a partnership or other pass-through entity; (iii) which holds Portugal Telecom's ordinary shares or ADSs as a part of an integrated investment (including a ''straddle'') comprised of the ordinary shares or ADSs and one or more other positions; or (iv) whose functional currency is not the U.S. dollar. This discussion generally applies only to U.S. Holders that hold the ordinary shares or ADSs as capital assets.

In addition, the following discussion does not address alternative minimum tax considerations or any aspect of state, local or non-U.S. tax laws (other than certain Portuguese tax laws).

The description of the Portuguese and U.S. federal income tax laws and practices set forth below is based on the laws as in force and as applied in practice on the date of this Form 20-F, including the U.S. Internal Revenue Code of 1986, as amended, hereinafter referred to as the ''Code,'' its legislative history, existing and proposed regulations thereunder, published rulings and court decisions, as well as The Convention Between the United States of America and the Portuguese Republic for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income, including the protocol thereto, hereinafter referred to as the ''Tax Treaty.'' These laws and practices and the Tax Treaty may be subject to change, possibly on a retroactive basis. This section is further based in part upon the representations of The Bank of New York as depositary and on the assumption that each obligation in the Amended and Restated Deposit Agreement, dated as of June 25, 1999, which governs Portugal Telecom's ADSs and any related agreement will be performed in accordance with its terms.

As used in this section, the term ''U.S. Holder'' means a beneficial owner of ordinary shares or of ADSs that is:

• an individual citizen or resident of the U.S.;
• a corporation or other entity taxable as a corporation organized under the laws of the U.S. or of any state thereof or the District of Columbia;
• an estate the income of which is included in gross income for U.S. federal income tax purposes regardless of source; or
• a trust (a) the administration of which is subject to the primary supervision of a U.S. court and that has one or more U.S. persons who have authority to control all substantial decisions of the trust or (b) that was in existence on August 20, 1996, was treated as a U.S. person under the Code on the previous day, and elected to continue to be so treated.

The application of the Tax Treaty, as described below, to U.S. Holders is conditioned upon, among other things, that the U.S. Holder:

• is a resident of the U.S. for purposes of the Tax Treaty;
• is entitled to the benefits of the Tax Treaty under the limitations of benefit provisions contained in Article 17 of the Tax Treaty; and
• does not have a fixed place of business or a permanent establishment in Portugal to which its ownership of ordinary shares or ADSs is attributable.

For purposes of the Tax Treaty and for U.S. federal income and Portuguese tax purposes, a U.S. Holder of ADSs will be treated as the beneficial owner of the underlying ordinary shares represented by the ADSs.

We urge prospective investors to consult their own tax advisors as to the tax consequences of the acquisition, ownership and disposition of the ordinary shares and ADSs, including, in particular, whether they are eligible for the benefits of the Tax Treaty and any tax consequences arising under any other applicable tax laws of the United States or Portugal or any other jurisdiction.

Dividends

Portuguese Taxation. The general rate of withholding tax on dividends in Portugal is currently 25% for both Portuguese residents and non-residents. Dividends placed at the disposal in bank omnibus accounts (except where the identity of the effective beneficiary is disclosed) are subject to withholding tax at a rate of 30%.

Under the Tax Treaty, the withholding tax rate on dividends distributed to U.S. tax residents may be reduced, as a general rule, to 15%. In order to apply the reduced treaty rate, Portugal Telecom must have confirmation that each shareholder is eligible for the benefits of the Tax Treaty. A specific form (Form 21-RFI of the Tax and Customs Authority (AT—Autoridade Tributaria e Aduaneira ´ ) of the Portuguese Ministry of Finance), duly certified by the U.S. Internal Revenue Service, must be received by Banco Esp´ırito Santo, the custodian for the depositary, if you are a holder of ADSs, or your financial intermediary, if you are a holder of Portugal Telecom ordinary shares, prior to the date the dividends are made available to shareholders. If this form is not available as of the relevant date, Portuguese withholding tax will be levied at the 25% rate. If you are able to submit the form to the custodian for the depositary, if you are a holder of ADSs, or to your financial intermediary, if you are a holder of ordinary shares no later than the 20th day of the month following the payment of the dividend, we believe that the custodian or the financial intermediary, as the case may be, should release the 10% excess Portuguese withholding tax to you. However, we cannot guarantee that the custodian or the financial intermediary will do so.

In addition, the 10% excess Portuguese withholding tax may be subsequently reimbursed by the Portuguese tax authorities pursuant to specific claims of individual shareholders on Form 22-RFI of the Tax and Customs Authority of the Portuguese Ministry of Finance, duly certified by the U.S. Internal Revenue Service and presented to the Portuguese tax authorities within two years following the last day of the year when the dividends were made available.

If you are a trust holding ADSs or ordinary shares, you should be aware that, under a guidance note issued by the Portuguese tax authorities, in order to benefit from the Tax Treaty provisions, in addition to the above-mentioned forms, you should be able to prove that:

• You are the beneficial owner of the dividends; and
• You are entitled to the benefits of the Tax Treaty under the limitations of benefit provisions contained in Article 17 of the Tax Treaty and in paragraph 3 of the Protocol attached to it.

If you are an investment or pension fund holding ADSs or ordinary shares, you should be aware that, under the same guidance note issued by the Portuguese tax authorities, in addition to the abovementioned forms, you should be able to prove that:

• You are a ''person'' for the purposes of the Tax Treaty;
• You are liable for tax in the United States (i.e. you are not treated as a pass-through entity), regardless of the tax treatment that may occur at the level of the unitholders/shareholders; and
• You are the beneficial owner of the dividends.

According to an administrative ruling issued by the Portuguese tax authorities, the compliance with the requirement described in the second bullet point above should be certified by the U.S. Internal Revenue Service, under a Form 6166, together with a statement issued by the entity receiving the dividends, in which it certifies that requirements foreseen in Article 17 (limitation on benefits) of the Tax Treaty are met.

Although Portuguese law states that the excess withholding tax should be reimbursed within one year from the date the claim was submitted, we cannot guarantee if or when you will receive any reimbursement of the 10% excess Portuguese withholding tax even if you fill out Form 21-RFI or Form 22-RFI to claim eligibility for the benefits of the Tax Treaty.

Please contact your tax advisor if you wish to fill out Form 21-RFI or Form 22-RFI to claim eligibility for the benefits of the Tax Treaty. You should know that receiving certification of a Form 21-RFI or Form 22-RFI from the U.S. Internal Revenue Service can be a lengthy process. You should therefore contact your tax advisor promptly after learning of any proposed or paid dividend.

U.S. Federal Income Taxation. Other than certain pro rata distributions discussed below, distributions paid by Portugal Telecom (including the amount of any Portuguese taxes withheld therefrom) will be includible in the gross income of a U.S. Holder as foreign source dividend income to the extent that such distributions are paid out of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. U.S. Holders will not be entitled to claim a dividends received deduction with respect to dividends distributed by us.

The U.S. dollar value of any cash distribution paid in Euros, including the amount of any Portuguese taxes withheld therefrom, will be equal to the U.S. dollar value of the Euros calculated by reference to the spot exchange rate in effect on the date of receipt by the U.S. Holder, in the case of ordinary shares, or by The Bank of New York as depositary, in the case of ADSs, regardless of whether the payment is in fact converted into U.S. dollars. A U.S. Holder should not recognize any foreign currency gain or loss if such Euros are converted into U.S. dollars on the day the U.S. Holder or The Bank of New York as depositary, as the case may be, receives the Euros. If the Euros are not converted into U.S. dollars on the date of receipt, however, a U.S. Holder may recognize gain or loss

<-- PDF CHUNK SEPARATOR -->

upon a subsequent sale or other disposition of the Euros (including an exchange of the Euros for U.S. dollars). Such gain or loss, if any, will be ordinary income or loss for U.S. federal income tax purposes and will be U.S. source gain or loss.

Subject to certain conditions and limitations, Portuguese tax withheld with respect to dividend distributions in accordance with Portuguese law may be eligible for credit against a U.S. Holder's federal income tax liability. A U.S. Holder will be denied a foreign tax credit with respect to Portuguese withholding tax on dividends from us if such U.S. Holder has not held the ADSs or ordinary shares for a minimum period during which it is not protected from risk of loss or to the extent such U.S. Holder is under an obligation to make certain related payments with respect to substantially similar or related property. As an alternative to claiming a foreign tax credit, a U.S. Holder may claim a deduction for Portuguese withholding tax, but only for a year for which such U.S. Holder elects to do so with respect to all foreign income taxes. If a U.S. Holder is denied a foreign tax credit because of the holding period requirement described above, however, the U.S. Holder may claim a deduction for the taxes for which the credit is disallowed even if such U.S. Holder claimed the foreign tax credit for other taxes in the same taxable year. The overall limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income.

Dividends distributed by Portugal Telecom with respect to ordinary shares or ADSs generally should constitute ''passive category income'' or, in the case of certain holders, ''general category income'' for U.S. foreign tax credit limitation purposes.

Foreign tax credits that were not used due to the foreign tax credit limitation may generally be carried back one year and forward ten years, subject to the limitations referred to above. The rules relating to the determination of the foreign tax credit are complex, and therefore, each U.S. Holder is urged to consult with its tax advisor to determine whether and to what extent such holder would be entitled to this credit.

Dividends paid to a non-corporate U.S. Holder on or before December 31, 2012 that constitute qualified dividend income will be taxable to the holder at a maximum rate of 15%, provided certain holding period and other requirements are met. Dividends received from ''qualified foreign corporations'' will generally qualify as qualified dividend income. A non-U.S. corporation that is not a ''passive foreign investment company'' generally will be considered to be a qualified foreign corporation with respect to dividends paid on its shares (or ADSs issued in respect of the shares) if (i) the shares (or ADSs) are readily tradable on an established securities market in the United States or (ii) the non-U.S. corporation is eligible for the benefits of a comprehensive income tax treaty with the U.S. which the U.S. Treasury Department determines to be satisfactory for these purposes and which includes an exchange of information provision. Ordinary shares (or ADSs issued in respect of the shares) will be considered to be readily tradable on an established securities market in the United States if the ordinary shares (or ADSs) are listed on a nationally registered stock exchange (such as the New York Stock Exchange). In addition, the U.S. Treasury Department has determined that the Tax Treaty meets these requirements, and we believe we are eligible for the benefits of the Tax Treaty. Accordingly, unless we are treated as a ''passive foreign investment company,'' the dividends that we pay in respect of our ordinary shares or ADSs will generally be qualified dividend income. Special rules apply for purposes of determining the recipient's investment income (which limits deductions for investment interest) and foreign income (which may affect the amount of foreign tax credit) and to certain extraordinary dividends. We urge each non-corporate U.S. Holder to consult its own tax advisor regarding the possible applicability of the 15% rate and the related restrictions and special rules.

Distributions in excess of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles, will first be treated as a tax-free return of capital to the extent of the U.S. Holder's adjusted tax basis in our ordinary shares or ADSs, and thereafter as capital gain from the sale of ordinary shares or ADSs. Consequently, such distributions in excess of our current and

accumulated earnings and profits would generally not give rise to foreign source income and a U.S. Holder would generally not be able to use the foreign tax credit arising from any Portuguese withholding tax imposed on such distributions unless such credit can be applied (subject to applicable limitations) against U.S. federal income tax due on other foreign source income in the appropriate category for foreign tax credit purposes. However, we do not expect to keep earnings and profits in accordance with U.S. federal income tax principles. Therefore, U.S. Holders should expect that a distribution will generally be treated as a dividend (as discussed above).

Pro rata distributions of ordinary shares or rights to our shareholders (including U.S. Holders of ADSs) generally should not be subject to U.S. federal income tax.

Capital Gains

Portuguese Taxation. Capital gains derived by a U.S. Holder from the sale or other disposition of ADSs or ordinary shares (including deposits and withdrawals of ordinary shares in exchange for ADSs) will, under the Tax Treaty, not be subject to Portuguese capital gains tax.

U.S. Federal Income Taxation. Gains or losses realized by a U.S. Holder on the sale or other disposition of ordinary shares or ADSs will be subject to U.S. federal income taxation in an amount equal to the difference between the amount realized on such disposition and such U.S. Holder's tax basis in the ordinary shares or ADSs. Any gain or loss realized by a U.S. Holder on the sale or other disposition of ordinary shares or ADSs generally will be a capital gain or loss and generally will be a long-term capital gain or loss if, on the date of sale, such shares or ADSs were held for more than one year. Net capital gain of a non-corporate U.S. Holder that is recognized from the sale of ordinary shares or ADSs in taxable years beginning on or before December 31, 2012 is generally taxed at a maximum rate of 15% where the holder has a holding period of more than one year. The deductibility of capital losses is subject to limitations.

Any gain or loss realized by a U.S. Holder on the sale or other disposition of ordinary shares or ADSs generally should be from sources within the U.S. for foreign tax credit limitation purposes. Deposits and withdrawals of ordinary shares by U.S. Holders in exchange for ADSs should not be subject to U.S. federal income tax.

Passive Foreign Investment Company

We do not believe that we are, for U.S. federal income tax purposes, a ''passive foreign investment company,'' and we expect to operate in such a manner so as not to become a ''passive foreign investment company.'' If, however, we are or become a ''passive foreign investment company,'' U.S. Holders could be subject to additional U.S. federal income taxes on gain recognized with respect to the ordinary shares or ADSs and on certain distributions, plus an interest charge on certain taxes treated as having been deferred under the ''passive foreign investment company'' rules.

Reportable Transactions

Under applicable U.S. Treasury regulations, U.S. Holders that participate in ''reportable transactions'' (as defined in the regulations) must attach to their federal income tax returns a disclosure statement on Form 8886. U.S. Holders should consult their own tax advisors as to the possible obligation to file Form 8886 with respect to the acquisition, ownership or disposition of ordinary shares or ADSs, or any related transaction, including without limitation, the disposition of any Euros (or other foreign currency) received as a dividend or as proceeds from the sale of the ordinary shares or ADSs.

U.S. Information Reporting and Back-up Withholding

In general, U.S. information reporting will apply with respect to dividends paid on or proceeds of the sale or other disposition of an ordinary share or ADS that are paid to a U.S. Holder within the U.S. (and, in certain cases, outside the U.S.), unless the U.S. Holder establishes a basis for exemption. A back-up withholding tax may apply to such payments if the U.S. Holder fails to provide a taxpayer identification number or certification of other exempt status or fails to report in full dividend and interest income. Any amounts withheld under the back-up withholding rules will generally be allowed as a refund or a credit against a U.S. Holder's U.S. federal income tax liability, provided that the required information is furnished to the Internal Revenue Service.

Documents on Display

We are subject to the informational reporting requirements of the U.S. Securities Exchange Act of 1934, as amended, which requires that we file periodic reports and other information with the SEC. As a foreign private issuer, we file annual reports on Form 20-F as opposed to Form 10-K. We do not file quarterly reports on Form 10-Q but furnish reports on Form 6-K.

Our reports and other information filed by us with the SEC may be inspected and copied by the public at the public reference facilities maintained by the SEC at Station Place, 100 F Street, N.E., Room 1580, Washington, D.C. 20549 and are also available on the website of the SEC at http://www.sec.gov. In addition, reports and other information concerning us may be inspected at the offices of the New York Stock Exchange, Inc., 20 Broad Street, New York, New York 10005, on which our ADSs are listed.

We furnish The Bank of New York, as the depositary of our ADSs, with annual reports in English, which include a review of operations and our audited consolidated financial statements prepared in accordance with IFRS, and our annual report on Form 20-F. We also furnish the depositary with six-month reports in English, which include semi-annual consolidated financial information prepared in accordance with IFRS. Upon our request, the depositary will promptly mail such reports to all record holders of ADSs. We also furnish to the depositary, in English, all notices of shareholders' meetings and other reports and communications that are made generally available to our shareholders. Upon our request, the depositary will make such notices, reports and communications available to holders of ADSs and will mail to all record holders of ADSs a notice containing a summary of the information contained in any notice of a shareholders' meeting it receives.

As a foreign private issuer, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of proxy statements. As a foreign private issuer, we are also exempt from the rules under the Exchange Act relating to short-swing profit disclosure and liability.

ITEM 11—QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our most significant market risk exposures are interest rate risk and exchange rate risk and, to a lesser extent, commodity risk. We actively manage interest rate risk and foreign currency exchange rate risk through our regular operating and financing activities as well as through financial derivative instruments.

Derivative contracts are entered into with major financial institutions, after careful analysis and approval from our Executive Committee. We regularly review their market value and risks in order to assess and manage our exposure to market risk. The positions held by the Company, as well as the relevant financial markets, are regularly monitored. The fair value of these derivatives is determined on a regular basis, essentially based on market information, in order to assess the economic and financial implications of different scenarios.

Interest Rate Risk

Interest rate risk relates mainly to the impact of potential fluctuations in market interest rates on our financial expenses related to our floating rate debt and on the fair value of our fixed rate debt. Our policy consists of managing interest rate risk through a combination of fixed and floating rate debt instruments and derivatives. As of December 31, 2011, the total notional amount of our Euro interest rate swaps was A178.1 million.

As of December 31, 2011, taking into account interest rate swaps, approximately 61% of our total indebtedness carried fixed interest rates, compared to 91% at the end of 2010. This decrease in the weight of fixed rate indebtedness was primarily due to the acquisition of a interest in Oi, as most of Oi's indebtedness was at floating rates at the end of 2011.

We are exposed to interest rate risk primarily in the Euro zone and in Brazil. Our consolidated debt is subject to floating interest rates based on the following rates: (1) Euribor, applicable for certain loans obtained in the Euro zone; (2) TJLP (Taxa de Juros a Longo Prazo), a long-term interest rate set by the National Monetary Council in Brazil; (3) IPCA (´Indice Nacional de Pre¸cos ao Consumidor Amplo), a Consumer Price Index published by the Brazilian Institute for Geography and Statistics; (4) CDI (Cr´edito Depositario Interbanc ´ ario ´ ), an interbank rate for Brazilian real-denominated debt; and (5) Libor, an interbank rate for U.S. dollar-denominated debt.

In addition, the interest rates on some of the EIB loans are determined by reference to the EIB's internal interest rates, typically set at quarterly intervals. The EIB's internal interest rates depend on its cost of funds rather than on any specific base rate. Accordingly, it is not possible to state average interest rates or average spreads over a reference base rate for the floating rate EIB debt. Nevertheless, the EIB's interest rates are generally competitive. The EIB's internal floating rates remained close to Euribor flat rates during 2011. The floating interest rates on EIB loans have been swapped into fixed rates in previous years, using Euro interest rate swaps.

As of December 31, 2011, considering the effects of derivative transactions, 38.9% of our consolidated gross debt, amounting to approximately A4,779 million, was subject to floating interest rates. In addition, total consolidated cash and cash equivalents plus short-term investments amounting to A5,668 million as of December 31, 2011 also bears interest at floating rates, thus eliminating the interest rate risk on gross debt. Accordingly, our net exposure to floating interest rates amounted to a net cash position of approximately A889 million as of December 31, 2011. If all market interest rates had been lower (higher) by 1% during the year ended December 31, 2011, net interest expenses would have been higher (lower) by an amount of approximately A2.0 million. Interest rate risks also result from exposure to changes in the fair value of our long-term fixed-rate debt due to changes in market interest rates.

Exchange Rate Risk

Portugal Telecom is exposed to exchange rate risk mainly due to investments in non-Euro countries, namely Brazil, and non-Euro denominated long-term debt. We are exposed to exchange rate risk between Brazilian Reais and Euros with respect to our Brazilian assets that are not hedged by Brazilian Real-denominated debt. Following the disposal of Vivo, as of December 31, 2010, the net exposure (assets minus liabilities, net of non-controlling interests) to Brazil was not significant. However, for the year ended December 31, 2011 and future periods, our exposure to the Brazilian Real has again become significant because of our investment in Oi completed on March 28, 2011.

The risks related to our investments in foreign currencies relate primarily to our investments in Oi and Contax. As of December 31, 2011, the net exposure (assets minus liabilities, net of non-controlling interests) in Brazil amounted to R\$8,667 million (approximately A3,587 million at the Euro/Real

exchange rate on December 31, 2011). We do not have financial instruments in place to hedge the exchange risk on our investments in foreign companies.

As of December 31, 2011, the risks related to debt denominated in currencies different from our subsidiaries' or investees' functional currencies were primarily related to foreign currency debt contracted by Oi and its subsidiaries, which represented about 29.9% of its gross debt. In order to minimize its exposure, Oi has entered into foreign exchange hedging contracts with financial institutions. Out of Oi's debt denominated in foreign currency as of December 31, 2011, 96.2% is protected through exchange rate swaps, currency forwards and foreign currency-denominated cash applications, while the remaining 3.8%, amounting to R\$319.0 million (A34.0 million, representing our proportionally consolidated 25.6% economic stake) is exposed to the risk of changes in the US\$/Real exchange rate.

The effects of hypothetical changes of relevant risk variables on our income statement and shareholders' equity are as follows:

• the impact of the appreciation (devaluation) of the Real against the Euro by R\$0.10, from 2.42 to 2.32 (2.52), would imply an increase (decrease) in Portugal Telecom's net assets as of December 31, 2011 of approximately A155 million (A143 million), which corresponds to currency translation adjustments on Brazilian investments;
• all other variables being equal, the impact of the appreciation (devaluation) of the U.S. Dollar against the Real by R\$0.10 during 2011 would imply an increase (reduction) in the contribution of Oi to our financial expenses by approximately A0.1 million, as a result of the portion of Oi's debt denominated in foreign currencies that is not protected through derivative financial instruments or cash applications denominated in foreign currencies; and
• most non-derivative financial assets and liabilities are denominated in the applicable functional currency either directly or indirectly through the use of derivatives. Changes in exchange rates would have no material effects on the income statement and shareholders' equity of the companies where those assets and liabilities are recorded.

Our total net exposure to the U.S. dollar, including our indebtedness, cash and derivatives, amounted to US\$46.6 million as of December 31, 2011, compared to US\$10.8 million as of December 31, 2010.

Equity Price Risk

Pursuant to the 3% share buyback announced in 2005, we had entered into equity swaps for 20,640,000 of our own shares, which were recognized as an effective acquisition of treasury shares and had a carrying value of A178.1 million as of December 31, 2011, corresponding to an average price per share of A8.6275. These equity swaps had maturities of twelve months as of December 31, 2011.

Tabular Information on Market Risk Sensitive Instruments

The following tables provide information about our debt and derivative instruments as of December 31, 2011 that are sensitive to changes in interest rates and exchange rates. The tables present principal cash flows and average interest rates (unless otherwise stated) by expected maturity dates. The information concerning debt, namely average interest rates and fair value amounts, takes into account related derivatives entered into with the purpose of hedging debt's interest rate and/or exchange rate risk. The amounts presented in the tables below are stated in Euro because the Euro is our reporting currency. The exchange rates used are those quoted by the Bank of Portugal for December 31, 2011.

The two final tables present additional information about all derivative contracts we have entered into.

In addition to these tables, Note 45 to our audited consolidated financial statements, which is incorporated herein by reference, includes sensitivity analysis disclosure relating to instruments subject to interest rate risk and exchange rate risk.

3.	Cable, telex and facsimile transmission expenses expressly provided under the Deposit Agreement
4.	Expenses incurred by the depositary in the conversion of foreign currency	Amounts in Euros received by way of dividends or other distributions or the net proceeds from the sale of securities, property or other rights in respect of ADSs

ITEM 14—MATERIAL MODIFICATIONS TO THE RIGHTS OF SECURITY HOLDERS AND USE OF PROCEEDS

ITEM 15—CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We carried out an evaluation under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our ''disclosure controls and procedures'' for the year ended December 31, 2011. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error, and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that the disclosure controls and procedures were effective in providing reasonable assurance that information required to be disclosed in the reports we file and submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the applicable rules and forms, and that it is gathered and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management's Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not necessarily prevent or detect some misstatements. It can only provide reasonable assurance regarding financial statement preparation and presentation. Also, projections of any evaluation of effectiveness for future periods are subject to the risk that controls may become inadequate because of changes in conditions or because the degree of compliance with the polices or procedures may deteriorate over time.

Management assessed the effectiveness of its internal control over financial reporting for the year ended December 31, 2011. The assessment was based on criteria established in the framework ''Internal Controls—Integrated Framework'' issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on the assessment, our management has concluded that as of December 31, 2011, our internal control over financial reporting was effective.

The effectiveness of internal control over financial reporting as of December 31, 2011 has been audited by Deloitte & Associados, SROC, S.A., an independent registered public accounting firm, as stated in their attestation report, which is included under ''Item 18—Financial Statements.''

Changes in Internal Control Over Financial Reporting

There were no material changes in our internal control over financial reporting during the period covered by this Annual Report on Form 20-F that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 16A—AUDIT COMMITTEE FINANCIAL EXPERT

Mario Jo ´ ao de Matos Gomes, who is a member of the Audit Committee elected on March 27, ˜ 2009, has been determined by our Board of Directors to be an ''Audit Committee Financial Expert,'' as that term is defined in Item 16A of Form 20-F, and to be independent under the standards of the New York Stock Exchange. See ''Item 6—Directors, Senior Management and Employees—Directors and Senior Management'' for information regarding the experience of Mr. Gomes. Mr. Gomes is also an expert in accordance with Portuguese requirements.

ITEM 16B—CODE OF ETHICS

Our Board of Directors has adopted a Code of Ethics that applies to all of its employees, including the Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer. In addition, the Board of Directors adopted has a Code of Ethics applicable to its financial officers. Both Codes of Ethics are publicly available on our official website at www.telecom.pt. Copies of the Codes of Ethics are also available without charge upon request to our Investor Relations office.

Under our Code of Ethics for all employees, whenever an employee is called upon to participate in decision processes that involve organizations with which they work or have worked or that involve people who are or have been connected to them by ties of kinship, they must inform their superiors of those connections. In addition, under our Code of Ethics applicable to financial officers, all senior financial officers are required to inform the Chairman of our Audit Committee of any family relationship to the second degree with people who are exercising external audit functions for the Portugal Telecom Group and of any relevant facts that may, directly or indirectly, give rise to a real or potential conflict of interest. In particular, these officers are required to inform the General Secretary of the Portugal Telecom Group of any position in any company outside the Portugal Telecom Group, non-profit organization or public institution.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of Portugal Telecom, SGPS, S.A. Lisbon, Portugal

We have audited the accompanying consolidated statements of financial position of Portugal Telecom, SGPS, S.A. and subsidiaries (the ''Company'') as of December 31, 2011 and 2010 and the related consolidated statements of income, comprehensive income, changes in shareholders' equity and cash flows for each of the three years in the period ended December 31, 2011. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States of America). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatements. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall consolidated financial statements presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Portugal Telecom, SGPS, S.A. and subsidiaries as of December 31, 2011 and 2010, and the consolidated results of their operations and their consolidated cash flows for each of the three years in the period ended December 31, 2011, in conformity with International Financial Reporting Standards as adopted by the European Union and International Financial Reporting Standards as issued by the International Accounting Standards Board.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States of America), the Company's internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated April 27, 2012 expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of Portugal Telecom, SGPS, S.A. Lisbon, Portugal

We have audited the internal control over financial reporting of Portugal Telecom, SGPS, S.A. and subsidiaries (the ''Company'') as of December 31, 2011, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States of America). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal Control— Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States of America), the consolidated financial statements as of and for the year ended December 31, 2011 of the Company and our report dated April 27, 2012 expressed an unqualified opinion on those financial statements.

1. Introduction

a) Parent company

Portugal Telecom, SGPS, S.A. (''Portugal Telecom'') and its subsidiaries (''Group'', ''Portugal Telecom Group'', or ''the Company'') are engaged in rendering a comprehensive range of telecommunications and multimedia services in Portugal, Brazil and other countries in Africa and Asia.

Portugal Telecom was incorporated on 23 June 1994, under Decree-Law 122/94, as a result of the merger, effective 1 January 1994, of Telecom Portugal, S.A., Telefones de Lisboa e Porto, S.A. (''TLP'') and Teledifusora de Portugal, S.A. (''TDP''). As a result of the privatization process, between 1 June 1995 and 4 December 2000, Portugal Telecom's share capital is mainly owned by private shareholders. On 12 December 2000, Portugal Telecom, S.A. changed its name to Portugal Telecom, SGPS, S.A., and became the holding company of the Group.

On 26 July 2011, Portugal Telecom's General Meeting of Shareholders approved an amendment to the Company's Bylaws that eliminated the special rights granted to the 500 Class A shares, the so-called ''golden share'' (Note 44).

The shares of Portugal Telecom are traded on the Euronext Stock Exchange and on the New York Stock Exchange.

b) Corporate purpose

Portugal Telecom Group is engaged in rendering a comprehensive range of telecommunications and multimedia services in Portugal, Brazil and other countries in Africa and Asia.

Portugal

In Portugal, fixed line services are rendered by PT Comunica¸coes, S.A. (''PT Comunica¸ ˜ coes'') ˜ under the provisions of the Concession Contract entered into with the Portuguese State on 20 March 1995, in accordance with Decree-Law 40/95, for an initial period of thirty years, subject to renewal for subsequent periods of fifteen years. On 11 December 2002, according to the terms of the Modifying Agreement to the Concession Contract, PT Comunica¸coes acquired the property of the Basic Network ˜ of Telecommunications and Telex (''Basic Network''). PT Comunica¸coes also renders Pay-TV services ˜ branded Meo, through IPTV, FTTH and DTH platforms, and Internet Service Provider (''ISP'') services to residential and small and medium size companies. In addition and following the merger of PT Prime—Solu¸coes Empresariais de Telecomunica¸ ˜ coes e Sistemas, S.A. (''PT Prime'') in 2011, PT ˜ Comunica¸coes renders data transmission services and is an ISP for large clients. ˜

Mobile services in Portugal are rendered by TMN—Telecomunica¸coes M ˜ oveis Nacionais, S.A. ´ (''TMN''), under a GSM license granted by the Portuguese State in 1992 (initial period of 15 years), which was renewed in 2007 until 16 March 2022, and a UMTS license obtained on 19 December 2000 (initial period of 15 years, renewable for an addition period of another 15 years). In December 2011, TMN acquired a fourth generation mobile license (''4G license''), under which will provide services as from 2012 through the Long Term Evolution (''LTE'') technology, which represents an evolution from the GSM technology that allows for higher levels of bandwith and speed.

1. Introduction (Continued)

Brazil

In Brazil, since March 2011, the Group renders telecommunication services through Telemar Norte Leste, S.A. (''Telemar'') and its subsidiaries, which operate under the brand name Oi, and renders corporate and call center services through Contax, S.A. (''Contax'') and its subsidiaries.

Oi is the leading provider of telecommunication services in the Brazilian market and the largest fixed telecommunications operator in South America in terms of active clients. Portugal Telecom completed the acquisition of a direct and indirect stake of a 25.3% in Telemar, for a total cash consideration of R\$ 8,256 million, equivalent to Euro 3,647 million (Note 2.b), through (1) the subscription of share capital increases undertaken, on 28 March 2011, by Telemar Participa¸coes, S.A. ˜ (''Telemar Participa¸coes''), Tele Norte Leste Participa¸ ˜ coes, S.A. (''TNL'') and Telemar, and (2) the ˜ acquisition of a 35% stake in each of the two main shareholders of Telemar Participa¸coes, AG Telecom ˜ Participa¸coes, S.A. (''AG'') and LF Tel, S.A. (''LF''). This transaction was completed following the ˜ Memorandum of Understanding entered into, on 28 July 2010, by Portugal Telecom, AG and LF, which sets the principles for the development of a strategic partnership between Portugal Telecom and Oi Group.

The terms of the shareholders' agreements entered into by Portugal Telecom, AG and LF contain mechanisms designed to produce unanimous voting by these parties in meetings of the board of directors of Telemar Participa¸coes on strategic financial and operating decisions relating to the activity ˜ of the Oi Group. Therefore, in accordance with the provisions of IAS 31 Interests in Joint Ventures (''IAS 31''), the Company concluded that it contractually shares the control of Telemar Participa¸coes ˜ and that therefore this company is a jointly controlled entity. Notwithstanding the option included in IAS 31 to apply the equity method of accounting, Portugal Telecom, in line with the accounting policy used in previous years, has chosen to use the proportional consolidation method to recognize in the consolidated financial statements its investment in the jointly controlled entity Telemar Participa¸coes, ˜ which in turn fully consolidates TNL and Telemar and its subsidiaries. In connection with the acquisition process of the investment in Oi, Portugal Telecom acquired a direct and indirect interest in Telemar Participa¸coes of 25.6%, percentage that is considered in the proportional consolidation of this ˜ company and all its subsidiaries.

The purpose of the strategic partnership between Portugal Telecom and Oi is to develop a global telecommunications platform that will allow for cooperation in diverse areas, with a view to, among other things, sharing best practices, achieving economies of scale, implementing research and development initiatives, developing new technologies, expanding internationally, particularly in Latin America and Africa, diversifying the services provided to customers, maximizing synergies and reducing costs, and seeking to offer constant high quality services to our corporate and individual customers, while creating and adding value for our shareholders.

Under the strategic partnership between Portugal Telecom and Oi, it was envisaged that, amongst other purposes, Oi would use part of the proceeds received from the share capital increase for the acquisition of up to 10% of Portugal Telecom's share capital. Up to 31 December 2011, Oi acquired 64,557,566 shares of Portugal Telecom (Note 23), representing 7.2% of Portugal Telecom's share capital. Portugal Telecom's share in this investment was classified as treasury shares in its Consolidated

1. Introduction (Continued)

Statement of Financial Position and amounted to Euro 148 million as at 31 December 2011 (Note 44.2), including Euro 61 million (Note 2.b) related to shares acquired before the end of March 2011 and Euro 87 million (Note 47.l) that relates to shares acquired during the second quarter of 2011.

Contax is one of the leading corporate services company and the leader in contact centre services in Brazil. On 28 March 2011, Portugal Telecom concluded the acquisition of a 16.2% stake in CTX Participa¸coes S.A. (''CTX'') for a consideration of R\$ 181 million, equivalent to Euro 80 million ˜ (Note 2.b). As a result of this acquisition, Portugal Telecom acquired a direct (16.2%) and indirect stake (25.8%, via AG and LF) of 42.0% in CTX and an indirect stake of 14.1% in Contax. CTX, which controls and fully consolidates Contax, is proportionally consolidated in Portugal Telecom's financial statements, considering the corporate governance rights attributed to Portugal Telecom under the shareholders agreements entered into by the Company.

The final step of the acquisition of Contax consisted of the acquisition of Dedic/GPTI (Portugal Telecom's Business Process Outsourcing provider) by Contax and was completed on 1 July 2011, as the Board of Directors and the Shareholders' Meetings of Dedic, CTX and Contax approved the following operations: (1) the exchange of Portugal Telecom's investment in Dedic/GPTI for a 7.6% stake in Contax; (2) the exchange of a 1.3% stake in Contax held by Portugal Telecom for an additional 3.7% stake in CTX; and (3) the disposal by Portugal Telecom to CTX of a 2.0% stake in Contax for a total amount of R\$49.7 million (Euro 22 million). As a result of these operations, Portugal Telecom's direct and indirect stakes in CTX and Contax were increased from 42.0% to 44.4% and from 14.1% to 19.5%, respectively, and Dedic/GPTI became a wholly owned subsidiary of Contax and, as such, its assets, liabilities and results were proportionally consolidated as from 1 July 2011, together with Contax. Additionally, a total goodwill of Euro 28 million (Note 36) was recorded, corresponding to the difference between the fair value and the carrying amount of the net assets acquired by both Portugal Telecom and Contax.

In April 2011, moving ahead with its internationalization strategy, Contax completed the acquisition of 100% of Allus Global BPO Center (''Allus'') for an amount of R\$245 million (Note 2.b). Consequently, the results of Contax, which are proportionally consolidated in Portugal Telecom's Income Statement as from 1 April 2011, include the full consolidation of the results of Allus as from 1 May 2011. Allus is one of the largest contact center service providers in Latin America, with operations in Argentina, Colombia and Peru and has commercial activities in the United States and Spain. With this acquisition, Contax took an important step towards becoming one of the most complete global BPO (Business Process Outsourcing) providers, dedicated to support its clients throughout their entire customer relationship chain.

On 24 May 2011, in a pre-meeting of the shareholders of Telemar Participa¸coes, in accordance ˜ with the terms of the Shareholders Agreement of this company, it was approved to instruct the managements of Telemar Participa¸coes and of each of its controlled companies TNL, Telemar, Coari ˜ Participa¸coes (''Coari'') and Brasil Telecom (together ''Oi Companies'') to conduct the relevant analysis ˜ and implement the required procedures for the execution of a corporate reorganization of the Oi

companies (the ''Corporate Reorganization''). Regarding this corporate reorganization, the following should be mentioned:

• The main steps necessary to conclude this corporate reorganization include:
  • (a) The share exchange of newly issued shares of Coari for currently outstanding shares issued by Telemar, resulting in Telemar becoming a wholly-owned subsidiary of Coari;
  • (b) The merger of Coari into Brasil Telecom, with Coari ceasing to exist;
  • (c) The merger of TNL into Brasil Telecom, with TNL ceasing to exist; and
  • (d) The distribution of redeemable shares of Brasil Telecom exclusively to holders of Brasil Telecom prior to the merger, with cash redemption of such shares to be made immediately after their issuance for an amount of R\$1,502 million, which was reflected in the calculation of the exchange ratios. Considering the commitment underlying these operations, Brasil Telecom recognized this amount payable to its shareholders, including R\$740 million payable to its controlling shareholder Coari Participa¸coes (49.3%), which is ˜ fully owned by Telemar, and R\$762 million payable to non-controlling interests. Consequently, Portugal Telecom proportionally consolidated the liability related to non-controlling interests amounting to Euro 86 million (Notes 22 and 43) as at the date of the deliberation, which was included under the caption ''Other current liabilities''.

Following these operations, Brasil Telecom, which shall be renamed Oi, S.A., will consolidate all of the current equity interests of the Oi Companies, and will be the only of the Oi Companies to have its shares listed on the stock exchange.

• The main benefits associated with this reorganization include, among other things, simplifying the corporate structure of the Oi Companies, consolidating the Oi Companies' shareholders bases, significantly increasing the liquidity of the shares of the Oi Companies, consolidating the Oi Companies' balance sheets allowing for the definition of a long term dividend policy and reducing operational, administrative and financial costs.
• In order to conclude this corporate reorganization, TNL, Telemar and Brasil Telecom constituted Special Independent Committees, each of which negotiated the conditions of the transactions involving its company, including the definition of the exchange ratios, and submited its recommendations to the Board of Directors of each company.
• On 1 August 2011, as a result of the analysis made by each independent committees individually and the negotiations held among all, the independent committees informed the president of the Board of Directors of each of those companies about the exchange ratios recommended that the Oi Companies' respective Board of Directors should adopt in relation to the mergers of Coari and TNL into Brasil Telecom.
• On 27 February 2012, the shareholders meetings of the Oi Companies approved the Corporate Reorganization (Note 50).

Discontinued operations (Note 21)

On 27 September 2010, Portugal Telecom concluded the sale of its 50% stake in Brasilcel (the joint venture that controls Vivo) to Telefonica for a total consideration of Euro 7,500 million, having ´ received Euro 4,500 million on that day, Euro 1,000 million on 30 December 2010, totaling Euro 5,500 million in 2010 (Note 21), and Euro 2,000 million on 31 October 2011 (Note 21), in accordance with the terms of the agreement reached with Telefonica. Portugal Telecom recognized a ´ net gain of Euro 5,423 million (Note 21) on this sale.

As a result of the sale of the investment in Brasilcel, Portugal Telecom's former Brazilian mobile business was classified as a discontinued operation and accordingly: (1) the earnings of this business in 2010 until the completion of the disposal and in 2009 were presented in the Consolidated Income Statement under the caption ''Net income from discontinued operations''; and (2) cash flows from this business were also presented in the Consolidated Statement of Cash Flows under captions of cash flows from discontinued operations, together with the proceeds obtained with the sale in 2010.

2. Basis of presentation

The consolidated financial statements for the year ended 31 December 2011 were approved by the Board of Directors and authorized for issue on 22 March 2012.

Consolidated financial statements are presented in Euros, which is the functional currency of Portugal Telecom and of a significant part of the Group's operations. Financial statements of foreign subsidiaries are translated to Euros according to the accounting principles described in Note 3.q).

The consolidated financial statements of Portugal Telecom have been prepared in accordance with International Financial Reporting Standards (''IFRS'') as adopted by the European Union (''EU''), and include all interpretations of the International Financial Reporting Interpretation Committee (''IFRIC'') as at 31 December 2011, approved by the EU. For Portugal Telecom, no differences have been identified between IFRS as adopted by the EU and applied by Portugal Telecom and IFRS as published by the International Accounting Standards Board.

Consolidated financial statements have been prepared assuming the continuity of operations.

2. Basis of presentation (Continued)

The preparation of consolidated financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and of revenues and expenses during the reported periods (Note 3).

a) Consolidation principles

Controlled entities (exhibit I)

Portugal Telecom has fully consolidated the financial statements of all controlled entities. Control is achieved whenever the Group has the majority of the voting rights or has the power to govern the financial and operating policies of an entity and obtains the majority of the economic benefits and risks. In any case, where the Group does not have the majority of the voting rights but in substance controls the entity, the financial statements of the entity are fully consolidated.

The interest of any third party in the equity and net income of fully consolidated companies is presented separately in the Consolidated Statement of Financial Position and in the Consolidated Income Statement, under the caption ''Non-controlling interests'' (Note 22).

Assets, liabilities and contingent liabilities of an acquired subsidiary are measured at fair value at acquisition date. Any excess of the acquisition cost over the fair value of identifiable net assets is recognised as goodwill. If the acquisition cost is lower than the fair value of identifiable net assets acquired, the difference is recognised as a gain in the net income for the period. Non-controlling interests are presented proportionally to the fair value of identifiable net assets.

The results of subsidiaries acquired or sold during the period are included in the Consolidated Income Statement as from the effective date of the acquisition or up to the effective date of disposal.

All intra-group transactions and balances are eliminated in the consolidation process. Gains obtained in intra-group transactions are also eliminated in the consolidation process.

When necessary, adjustments are made to the financial statements of subsidiaries to adjust their accounting policies in line with those adopted by the Group.

Interests in joint ventures (exhibit II)

Portugal Telecom has proportionally consolidated the financial statements of jointly controlled entities beginning on the date the joint control is effective. Financial investments are classified as jointly controlled entities if the joint control agreement clearly demonstrates the existence of joint control.

Under the proportional consolidation method, assets, liabilities, income and expenses of the entity are added, on a proportional basis, to the corresponding consolidated caption.

Assets, liabilities and contingent liabilities of a joint venture are measured at fair value at acquisition date. Any excess of the acquisition cost over the fair value of identifiable net assets is recognised as goodwill. If the acquisition cost is lower than the fair value of identifiable net assets acquired, the difference is recognised as a gain in the net income for the period.

2. Basis of presentation (Continued)

Where necessary, adjustments are made to the financial statements of jointly controlled entities to adjust their accounting policies in line with those adopted by the Group.

Following the acquisition of the investments in Oi and Contax, which are classified as jointly controlled entities in accordance with IAS 31, Portugal Telecom proportionally consolidated its assets and liabilities as from 31 March 2011 and its earnings as from 1 April 2011.

As a result of the disposal of the 50% stake in Brasilcel, as mentioned above, Portugal Telecom's share in the earnings of this joint venture for all the periods presented was included under the caption ''Net income from discontinued operations'' (Note 21).

Investments in associates (exhibit III)

An associate is an entity over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policies of the entity but not to control or jointly control those policies.

Financial investments in associated companies are accounted for under the equity method adjusted, when applicable, to comply with Portugal Telecom's accounting policies. Under this method, investments in associated companies are carried at cost in the Consolidated Statement of Financial Position, adjusted periodically for the Group's share in the results of the associated company, recorded under the caption ''Equity in earnings of associated companies, net'' (Note 34). In addition, these financial investments are adjusted for any impairment losses that may occur.

Losses in associated companies in excess of the cost of acquisition are not recognised, except where the Group has assumed any commitment to cover those losses.

Dividends attributed by associated companies are recorded as a reduction to the carrying value of financial investments when they are declared.

Where necessary, adjustments are made to the financial statements of associated companies to adjust their accounting policies in line with those adopted by the Group.

Goodwill

Goodwill represents the excess of the acquisition cost over the Group's interest in the net fair value of the identifiable assets, liabilities and contingent liabilities of the subsidiary, jointly controlled or associated entity recognised at the date of acquisition, in accordance with IFRS 3 Business Combinations (''IFRS 3''). Considering the exception of IFRS 1 First-Time Adoption of IFRS, the Group used the provisions of IFRS 3 only for acquisitions occurred after 1 January 2004. Goodwill related to acquisitions made up to 1 January 2004 was recorded at the carrying amount of those acquisitions as of that date, and is subject to annual impairment tests thereafter.

Goodwill related to foreign investments is carried at the reporting currency of the investment, being translated to Euros at the exchange rate prevailing at the statement of financial position date. Exchange gains or losses are recognised in the Consolidated Statement of Comprehensive Income under the caption ''Foreign currency translation adjustments''.

2. Basis of presentation (Continued)

Goodwill related to subsidiaries and jointly controlled entities is recognized under the caption ''Intangible assets'' (Note 36) and is not amortised, but tested, at least on an annual basis, for impairment losses, which are recognised in net income in the period they occur, and cannot be reversed in a subsequent period. Goodwill related to associated companies is recognised under the caption ''Investments in group companies'' (Note 34). These investments are also tested for impairment losses.

On disposal of a subsidiary, jointly controlled entity or associate, the goodwill allocated to that investment is included in the determination of the gain or loss on disposal.

b) Changes in the consolidated Group

Acquisitions

On 28 March 2011, Portugal Telecom completed the acquisition of direct and indirect stakes in Telemar and Contax, following which Portugal Telecom proportionally consolidated its assets and liabilities as from 31 March 2011 and its earnings as from 1 April 2011, as explained above. The investment in Telemar was made through the acquisition of a direct stake in this company and indirectly through the acquisition of stakes in the share capital of its controlling shareholders, while the investment in Contax was made indirectly through the acquisition of direct stakes in the share capital of CTX and of its controlling shareholders. The investments in Telemar and Contax were acquired

2. Basis of presentation (Continued)

Oi Group is the leading provider of telecommunication services in the Brazilian market, providing these services through Telemar and its subsidiaries (Exhibit II), as follows:

• Telemar renders fixed telephone services in Region I of Brazil;
• TNL PCS, S.A. renders mobile telephone services in Regions I and III of Brazil (99.7% owned by Telemar);

• Several other companies, including holding companies and others rendering network services, data traffic services, financial services, services related to payment and credit systems and call center and telemarketing services.

Following these acquisitions, the Company performed a preliminary assessment of the fair value of the assets acquired and liabilities assumed under these businesses combinations and, consequently, the purchase price allocations may be subject to changes until the completion of the one year period from the acquisition date, as allowed by IFRS 3 Business Combinations. Nevertheless, the Company does not estimate material changes on its financial position resulting from possible changes in the allocation recorded in 2011. The detail of the fair value of net assets proportionally consolidated in Portugal Telecom's Statement of Financial Position related to Telemar (25.6%), Contax (42.0%) and its

2. Basis of presentation (Continued)

• (ii) This caption includes primarily prepaid expenses and non-current taxes receivable.
• (iii) Non-current taxes payable relate mainly to federal tax partial payment programmes in place in Brazil, under which companies enrolled a substantial portion of their tax debt to the National Treasury and the National Social Security Institute past due up to 30 November 2008.
• (iv) This caption includes primarily (1) dividends payable, which are included under the caption ''Other current liabilities'' of the Consolidated Statement of Financial Position, (2) non-current accounts payable, namely related to licenses payable to Anatel, and (3) deferred income.
• (v) As at 31 March 2011, Oi had a 3.1% stake in Portugal Telecom. This investment was recorded as treasury shares under Portugal Telecom's Consolidated Statement of Financial Position and was acquired under the strategic partnership entered into between Portugal Telecom and Oi (Note 1).
• (vi) Following the completion of the acquisition process of Oi, Contax and its controlling shareholders on 28 March 2011, Portugal Telecom proportionally consolidated the fair value of the net assets acquired for the first time as at 31 March 2011, based on the Euro/Brazilian Real exchange rate prevailing as at that date, which differs from the Euro/Brazilian Real exchange rate implicit in the transfers of funds from Portugal to Brazil for the payment of the purchase price. The impact of the difference between these exchange rates was recognized directly in shareholders' equity and included in the Consolidated Statement of Comprehensive Income under the caption ''Foreign currency translation adjustments''.
• (vii) In most business acquisitions, there is a part of the acquisition cost that is not capable of being attributed in accounting terms to the fair value of identifiable assets and liabilities assumed and is therefore recognized as goodwill. In the case of the acquisition of Oi and Contax, this goodwill is underpinned by a number of elements, which individually cannot be quantified reliably and isolated, and includes synergies resulting from cost savings, skilled workforce, core technological capabilities and established market reputation.

The fair value of the net assets acquired of Oi, Contax and its controlling shareholders was determined through various measurement methods for each type of asset or liability, based on the best available information. The advice of experts has also been considered in addition to the various other considerations made in determining the fair value of the net assets acquired. The fair value adjustments relate primarily to: (1) the mobile licenses held by TNL PCS, S.A. (''TNL PCS'') for Regions I and III and by 14 Brasil Telecom Celular, S.A. (''Brasil Telecom Celular'') for Region II, which are amortized up to 2038, the end of the first renewal period of these licenses; (2) the fixed line concessions held by Telemar Norte Leste for Region I and by Brasil Telecom for Region II, which are amortized up to 2025, the end of the initial period of these concessions; and (3) the customer base of Oi's mobile

The contribution of Oi, Contax and its controlling shareholders for Portugal Telecom's net income attributable to equity holders of the parent in the year ended 31 December 2011 was negative in Euro 32 million. Such contribution differs from the net income included in the financial statements of

On 7 February 2010, Portugal Telecom, through Dedic, a company that operates in the call centre business in Brazil, agreed to acquire a 100% equity stake in GPTI, S.A. (''GPTI''), a company which renders services related to information systems and technologies which are a complement to the services provided by Dedic. The purchase price of this acquisition included (1) the issuance of shares of Dedic corresponding to a 12.5% stake, and (2) an option granted to the former shareholder of GPTI to increase or decrease that stake up to 7.5%, depending on the operational and financial performance of GPTI during 2010 and 2011. As a result of this acquisition, which was completed through the issuance of shares of Dedic on 1 March 2010 (the effective date of the acquisition of control), the former shareholder of GPTI obtained a 12.5% stake in Dedic.

⁽i) The fair value adjustments related to intangible assets consist of the estimate fair value of recurring contracts entered into between GPTI and certain customers. The fair value adjustments related to non-current provisions correspond to the fair value of certain tax contingencies whose settlement was considered to be possible at the date of acquisition.

(ii) As mentioned above, the purchase price includes (a) 28 million Brazilian Reais (Euro 11 million) corresponding to the fair value of the share capital increase at Dedic at the acquisition date, and (b) 5 million Brazilian Reais (Euro 2 million) corresponding to the fair value as at 1 March 2010 of the option granted to the former shareholder of GPTI.

The contribution of GPTI for Portugal Telecom's results for the year ended 31 December 2010 was a net profit before non-controlling interests of approximately Euro 4 million, including operating revenues of Euro 56 million. The pro-forma of Portugal Telecom's consolidated operating revenues and

net income before non-controlling interests for the year ended 31 December 2010 as if GPTI had been consolidated as from 1 January 2010 are as follows:

	Reported figures	GPTI's results for January and February of 2010 Euro million	Pro-forma information
Operating revenues	3,742	8	3,751

Disposals

In 2010, Vivo was classified as a discontinued operation following the agreement reached by Portugal Telecom with Telefonica on 28 July 2010 for the disposal of its 50% stake in Brasilcel, which ´ was completed in September 2010. Consequently, financial information relating to this business was presented as a discontinued operation (Note 21).

Other corporate transactions

As explained in Note 1, on 1 July 2011, the Board of Directors and the Shareholders' Meetings of Dedic, Contax and CTX approved the following operations: (1) the exchange of Portugal Telecom's investment in Dedic/GPTI for a 7.6% stake in Contax; (2) the exchange of a 1.3% Portugal Telecom's stake in Contax for an additional 3.7% stake in CTX; and (3) the disposal by Portugal Telecom to CTX of a 2.0% stake in Contax for a total amount of R\$49.7 million. All these operations were recorded at fair value, including the exchange of the investment in Dedic and GPTI for an investment in Contax, which was recorded based on the related fair value attributed to the terms of the exchange. As a result of these operations, it was recorded a total goodwill of Euro 28 million (Note 36), corresponding to the difference between the fair value and the carrying amount of the net assets acquired by both Portugal Telecom and Contax. Basically, this goodwill represents the synergies resulting from the integration of these entities, since both operate in the call center business.

As a result of the operations mentioned above, Portugal Telecom's direct and indirect stakes in CTX and Contax were increased from 42.0% to 44.4% and from 14.1% to 19.5%, respectively, and Dedic/GPTI is no longer fully consolidated by Portugal Telecom as it became a wholly owned subsidiary of Contax. Consequently, Dedic/GPTI's assets, liabilities and results were proportionally consolidated as from 1 July 2011, together with Contax, while up to that date were fully consolidated in Portugal Telecom's financial statements. The detail of Dedic/GPTI's assets and liabilities that were fully

2. Basis of presentation (Continued)

consolidated as at 30 June 2011 and were then integrated in Contax and proportionally consolidated as from 1 July 2011, based on the Company's 44.4% effective stake in CTX, is as follows:

Except for the transactions mentioned above, there are no other relevant changes in the consolidation Group that occurred during the years ended 31 December 2011, 2010 and 2009.

3. Significant accounting policies, judgments and estimates

Significant accounting policies

a) Current classification

Assets to be realized within one year from the date of the Consolidated Statement of Financial Position are classified as current. Liabilities are also classified as current when they are due to be settled, or there is no unconditional right to defer its settlement, for a period of at least twelve months after the date of the Consolidated Statement of Financial Position.

b) Inventories

Inventories are stated at average acquisition cost. Adjustments to the carrying value of inventories are recognised based on technological obsolescence or slow moving.

c) Tangible assets

In 2008, Portugal Telecom changed the accounting policy regarding the measurement of real estate properties and ducts infra-structure from the cost model to the revaluation model, since it believes the

3. Significant accounting policies, judgments and estimates (Continued)

latter better reflects the economic value of those asset classes, given the nature of the assets revalued, which are not subject to technological obsolescence. The increase in tangible assets resulting from the revaluation reserves, which are non-distributable reserves, is being amortised in accordance with the criteria used to amortize the revalued assets. Portugal Telecom has adopted the policy to revise the revalued amount every 3 years.

The remaining tangible assets are stated at acquisition cost, net of accumulated depreciation, investment subsidies and accumulated impairment losses, if any. Acquisition cost includes: (1) the amount paid to acquire the asset; (2) direct expenses related to the acquisition process; and (3) the estimated cost of dismantling or removal of the assets (Notes 3.g and 43). Under the exception of IFRS 1, revaluation of tangible assets made, prior to 1 January 2004, in accordance with Portuguese legislation applying monetary indices, was not adjusted and was included as the deemed cost of the asset for IFRS purposes.

Tangible assets are depreciated on a straight-line basis from the month they are available for use, during its expected useful life. The amount of the asset to be depreciated is reduced by any residual estimated value. The depreciation rates used correspond to the following estimated average economic useful lives:

	Years
Buildings and other constructions	3 - 50
Basic equipment:
Network installations and equipment	7 - 40
Ducts infra-structure	40
Telephones, switchboards and other	3 - 10
Submarine cables	15 - 20
Satellite stations	5 - 7
Other telecommunications equipment .	4 - 10
Other basic equipment	4 - 20
Transportation equipment	4 - 8
Tools and dies	4 - 8
Administrative equipment	3 - 10
Other tangible fixed assets	4 - 8

Estimated losses resulting from the replacement of equipments before the end of their economic useful lives are recognised as a deduction to the corresponding asset's carrying value, against results of the period, as well as any impairment of these assets. The cost of recurring maintenance and repairs is charged to net income as incurred. Costs associated with significant renewals and betterments are capitalized if any future economic benefits are expected and those benefits can be reliably measured.

The gain or loss arising on the disposal or retirement of an asset is determined as the difference between the sales proceeds and the carrying amount of the assets, and is recognised in the Consolidated Income Statement under the caption ''Gains on disposals of fixed assets, net'' when occurred.

3. Significant accounting policies, judgments and estimates (Continued)

d) Intangible assets

Intangible assets are stated at acquisition cost, net of accumulated amortisation and accumulated impairment losses, if any. Intangible assets are recognised only if any future economic benefits are expected and those benefits as well as the cost of the asset can be reliably measured.

Intangible assets include mainly goodwill (Note 2.a), the acquisition of the Basic Network held by PT Comunica¸coes, telecommunications licenses and concessions related rights, mainly related to Oi and ˜ TMN, and software licenses.

Intangible assets, except goodwill, are amortised on a straight-line basis from the month they are available for use, during the estimated economic useful lifes or contractual periods if lower (including additional renewal periods if applicable), as follows:

Property of the Basic Network held by PT	Period of the concession (until 2025)
Comunica¸coes ˜
Telecommunications licenses and
concessions:
—UMTS license owned by TMN	Period of the license plus one renewal period (until 2030)
—LTE license owned by TMN	Period of the license plus one renewal period (until 2041)
—Oi's fixed concessions (held by Telemar	Period of the concessions (until 2025)
and Brasil Telecom)
—Oi's mobile licenses (held by TNL PCS	Period of the license plus one renewal period (until 2038)
and Brasil Telecom Celular)
Satellite capacity rights	Period of the contract (until 2015)
Software licenses	3 - 6
Other intangible assets	3 - 8

The renewal period of the licenses depends basically on the companies meeting certain pre-defined goals or obligations set out in the agreements under which those licenses were initially obtained.

e) Real estate investments

Real estate investments, which are included under the caption ''Other investments'' (Note 35), consist primarily of buildings and land held to earn rentals and/or capital appreciation, and not for use in the normal course of business (exploration, service render or sale).

These investments are stated at its acquisition cost plus transaction costs and reduced by accumulated depreciation (straight-line basis) and accumulated impairment losses, if any. Expenditures incurred (maintenance, repairs, insurance and real estate taxes) and any income obtained are recognised in the Consolidated Income Statement of the period.

Real estate investments are depreciated on a straight-line basis, during their expected useful lifes (Note 3.c).

3. Significant accounting policies, judgments and estimates (Continued)

f) Impairment of tangible and intangible assets, excluding goodwill

The Group performs impairment tests for its tangible and intangible assets if any event or change results in an indication of impairment. In case of any such indication, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss.

Where it is not possible to estimate the recoverable amount of an individual asset, the Group estimates the recoverable amount of the cash-generating unit to which the asset belongs. The recoverable amount is the higher of fair value less cost to sell and the value in use. In assessing fair value less cost to sell, the amount that could be received from an independent entity is considered, reduced by direct costs related to the sale. In assessing the value in use, the estimated future cash flows are discounted to their present value using a discount rate that reflects current market assessments of the time value of money and the specific risk to the asset.

If the recoverable amount of an asset is estimated to be less than its carrying amount, an impairment loss is recognised immediately in the Consolidated Income Statement.

Where an impairment loss subsequently reverses, the carrying amount of the asset is increased to the revised estimate of its amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognised for the asset in prior periods. A reversal of an impairment loss is recognised immediately in net income.

Tangible assets recognized according to the revaluation model are subject to periodic remeasurement. Any impairment loss of these assets is recorded as a reduction to the revaluation reserve initially recognized under shareholders' equity. Impairment losses in excess of the initial revaluation reserve are recognized in the Consolidated Income Statement.

g) Provisions, liabilities and contingent liabilities

Provisions are recognised when the Group has a present obligation as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Where any of the above mentioned criteria does not exist, or is not accomplished, the Group discloses the event as a contingent liability, unless the cash outflow is remote.

Provisions for restructuring are only recognised if a detailed and formal plan exists and if the plan is communicated to the related parties.

Provisions are updated on the date of the Consolidated Statement of Financial Position, considering the best estimate of the Group's management.

Obligations for dismantling and removal costs are recognised from the month the assets are in use and if a reliable estimate of the obligation is possible (Notes 3.c) and 43). The amount of the obligation is discounted, being the corresponding effect of time value recognised in net income, under the caption ''Net interest expense''.

3. Significant accounting policies, judgments and estimates (Continued)

h) Pension and pension supplement benefits

Under several defined benefit plans, PT Comunica¸coes and PT Sistemas de Informa¸ ˜ cao, S.A. ˜ (''PT SI'') were responsible to pay to a group of employees a pension or a pension supplement. Following the transfer in 2010 to the Portuguese State of the unfunded regulatory pension obligations, as explained in Note 14.1, PT Comunica¸coes and PT SI are responsible since December 2011 to pay ˜ only pension supplements. In order to finance these obligations, various funds were incorporated by PT Comunica¸coes (Note 14.1.1). ˜

Telemar and its subsidiaries sponsor private pension plans and other post retirement benefits for their employees, which are managed by two foundations. Telemar and its subsidiaries have defined contribution and defined benefit plans (Note 14.2).

The amount of the Group's liabilities with the defined benefit plans described above is estimated based on actuarial valuations, using the ''Projected Unit Credit Method''. The Group has elected to apply the option in IAS 19 to recognise actuarial gains and losses directly in the Consolidated Statement of Comprehensive Income, namely those resulting from changes in actuarial assumptions and from differences between actual data and actuarial assumptions.

Plan amendments related to reduction of the benefits granted to employees are recorded as prior years' service gains or losses. Prior years' service gains or losses related to vested rights are recognised under the caption ''Post retirement benefits'' when they occur and those related to unvested rights are recognised on a straight-line basis until they become vested, which usually corresponds to the retirement date. Gains obtained with the settlement of any plan are recognized when incurred under the caption ''Curtailment costs''.

Liabilities stated in the Consolidated Statement of Financial Position correspond to the difference between the Projected Benefit Obligation (''PBO'') related to pensions deducted from the fair value of pension fund assets and any prior years' service gains or losses not yet recognised.

For the plans that report an actuarial surplus, assets are recorded when there is an express authorization for offsetting them against future employer contributions, or if a reimbursement of the excess finance is expressly authorized or permitted.

Contributions made under defined contribution pension plans are determined based on actuarial calculations, when applicable, and recognised in net income when incurred. Under these plans, the sponsor does not have the legal or constructive obligation of making additional contributions, in the event the fund lacks sufficient assets to pay all employees the benefits related to the services provided in the current year and prior years.

i) Post retirement health care benefits

Under a defined benefit plan, PT Comunica¸coes and PT SI are responsible to pay, after the ˜ retirement date, health care expenses to a group of employees and its relatives. This health care plan is managed by Portugal Telecom—Associa¸cao de Cuidados de Sa ˜ ude (''PT-ACS''). In 2004, the Group ´

3. Significant accounting policies, judgments and estimates (Continued)

established PT Presta¸coes—Mandat ˜ aria de Aquisi¸ ´ coes e Gest ˜ ao de Bens, S.A. (''PT Presta¸ ˜ coes'') to ˜ manage an autonomous fund to finance these obligations (Note 14.1.2).

Telemar and its subsidiaries manage a defined benefit plan intended to provide medical care to retirees and survivor pensioners.

The amount of the Group's liabilities with respect to these benefits after retirement date is estimated based on actuarial valuations, using the ''Projected Unit Credit Method''. The Group has elected to apply the option in IAS 19 to recognise actuarial gains and losses in the Consolidated Statement of Comprehensive Income, namely those resulting from changes in actuarial assumptions and from differences between actual data and actuarial assumptions.

Plan amendments related to reduction of the benefits granted to employees are recorded as prior years' service gains or losses. Prior years' service gains or losses related to vested rights are recognised under the caption ''Post retirement benefits'' when they occur and those related to unvested rights are recognised on a straight-line basis until they become vested, which usually corresponds to the retirement date. Gains obtained with the settlement of any plan are recognized when incurred under the caption ''Curtailment costs''.

Accrued post retirement health care liabilities stated in the Consolidated Statement of Financial Position correspond to the present value of obligations from defined benefit plans, reduced by the fair value of fund assets and any prior years' service gains or losses not yet recognised.

For the plans that report an actuarial surplus, assets are recorded when there is an express authorization for offsetting them against future employer contributions, or if a reimbursement of the excess finance is expressly authorized or permitted.

j) Pre-retired and suspended employees

In connection with the programs related to employees that are under a suspended contract agreement or that have been pre-retired, the Group recognizes a liability in the Consolidated Statement of Financial Position equivalent to the present value of salaries payable up to the retirement age. The correspondent cost is recorded in the Consolidated Income Statement under the caption ''Curtailment costs'' (Note 14.1.3).

k) Grants and subsidies

Grants and subsidies from the Portuguese Government and from the European Union are recognised at fair value when the receivable is probable and the Company can comply with all requirements of the subsidy's program.

Grants and subsidies for training and other operating activities are recognised in net income when the related expenses are recognised. Grants and subsidies to acquire assets are deducted from the carrying amount of the related assets (Note 3.c).

3. Significant accounting policies, judgments and estimates (Continued)

l) Financial assets and liabilities

Financial assets and liabilities are recognised in the Group's Consolidated Statement of Financial Position when the Group becomes a party to the contractual provisions of the instrument.

(i) Receivables (Notes 26 and 27)

Trade receivables, loans granted and other receivables that have fixed or determinable payments and that are not quoted in an active market are classified as receivables or loans granted.

Trade receivables do not have any implicit interest and are presented at nominal value, net of allowances for estimated non-recoverable amounts, which are mainly computed based on (a) the aging of the receivables and (b) the credit profile of specific customers.

(ii) Financial liabilities and equity instruments

Financial liabilities and equity instruments issued by the Group are classified according to the substance of the contractual arrangements entered into and the definitions of a financial liability and an equity instrument. An equity instrument is any contract that evidences a residual interest in the assets of the Group after deducting all of its liabilities.

Equity instruments issued by the Group are recognised based on their proceeds, net of any issuance costs.

Exchangeable bonds issued by Portugal Telecom are recognised as compound instruments, comprising the following elements: (i) the present value of the debt, estimated using the prevailing market interest rate for similar non-convertible debt and recorded under debt liabilities; and (ii) the fair value of the embedded option for the holder to convert the bond into equity, recorded directly in shareholders' equity. As of the Consolidated Statement of Financial Position date, the debt component is recognised at amortised cost.

(iii) Bank loans (Note 38)

Bank loans are recognised as a liability based on the related proceeds, net of any transaction cost. Interest and other financial costs, which are computed based on the effective interest rate and include the recognition of up front fees, are recognised when incurred.

(iv) Accounts payable (Note 39)

Trade payables are recognised at nominal value, which is substantially similar to their fair value.

(v) Derivative financial instruments and hedge accounting (Note 45)

The activities of the Group are primarily exposed to financial risks related with changes in foreign currency exchange rates and changes in interest rates. The Group's policy is to contract

3. Significant accounting policies, judgments and estimates (Continued)

derivative financial instruments to hedge those risks, subject to detailed analysis of related economics and Executive Committee approval.

Derivative financial instruments are initially measured at fair value on the contract date, and are remeasured to fair value at subsequent reporting dates.

Hedge accounting

The provisions and requirements of IAS 39 must be met in order to qualify for hedge accounting. Currently, for accounting purposes, Portugal Telecom classifies certain derivative financial instruments as fair value and cash flow hedges.

Changes in the fair value of derivative financial instruments classified as fair value hedges are recognised in net income of the period, together with the changes in the value of the covered assets or liabilities related with the hedged risk.

The effective portion of the changes in fair value of derivative financial instruments classified as cash flow hedges is recognised directly in shareholders' equity, and the ineffective portion is recognised as financial results. When changes in the value of the covered asset or liability are recognised in net income, the corresponding amount of the derivative financial instrument previously recognised under ''Hedge accounting'' directly in shareholders' equity is transferred to net income.

Changes in fair value of derivative financial instruments that, in accordance with internal policies, were contracted to economically hedge an asset or liability but do not comply with the provisions and requirements of IAS 39 to be accounted for as hedges, are classified as ''derivatives held for trading'' and recognised in net income.

(vi) Treasury shares (Note 44)

Treasury shares are recognised as a deduction to shareholders' equity, under the caption ''Treasury shares'', at acquisition cost, and gains or losses obtained in the disposal of those shares are recorded under ''Accumulated earnings''.

Equity swaps on own shares that include an option exercisable by Portugal Telecom for physical settlement are recognised as a financial liability and a corresponding reduction of equity, and are accounted for as an acquisition of treasury shares on the inception date of the contract.

Portugal Telecom's shares acquired by any of its affiliated companies are recognized at acquisition cost as treasury shares based on the Company's interest in the entity that acquired those shares.

(vii) Cash and cash equivalents and short term investments (Note 25)

Cash and cash equivalents comprise cash on hand and demand bank deposits, due within three months or less from the date of acquisition, that are readily convertible to a known amount

3. Significant accounting policies, judgments and estimates (Continued)

of cash and are subject to an insignificant risk of changes in value. Cash and cash equivalents also includes deposits from customers and other entities that have not yet been cleared.

In the Consolidated Statement of Cash Flows, cash and cash deposits also includes overdrafts recognised under the caption ''Short-term debt''.

Short-term investments comprise investments for the purpose of generating investment returns, and they are therefore not classified as cash equivalents.

(viii) Qualified Technological Equipment transactions

In previous years, the Company entered into certain Qualified Technological Equipment transactions (''QTE''), whereby certain telecommunications equipment were sold to certain entities. Simultaneously, those foreign entities entered into leasing contracts with respect to the equipment with special purpose entities, which entered into conditional sale agreements to resell the related equipment to the Company. The Company maintains the legal possession of this equipment.

These transactions correspond to a sale and lease-back transaction, and the equipment continued to be recorded on the Company's Consolidated Statement of Financial Position. The Company obtained the majority of the economic benefits of these entities and therefore is exposed to the risks resulting from the activities of these special purpose entities. Accordingly, those entities were fully consolidated in the Company's financial statements. Consolidated current and non-current assets include an amount equivalent to the proceeds of the sale of the equipment (Note 32), and current and non-current liabilities include the future payments under the lease contract (Note 43).

m) Own work capitalized

Certain internal costs (materials, work force and transportation) incurred to build or produce tangible assets are capitalized only if:

• the tangible assets are identifiable;
• the tangible assets will generate future economic benefits which can be reliably estimated; and
• development expenses can be reliably measured.

The amounts capitalized are deducted from the corresponding operating costs incurred and no internally generated margin is recognised. When any of the above mentioned criteria is not met, the expense is recognised in net income.

Expenses incurred during investigation are recognised in net income when incurred.

n) Leasings (the company as a lessee)

Leases are classified as finance leases whenever the terms of the lease transfer substantially all the risks and rewards of ownership to the lessee. All other leases are classified as operating leases

3. Significant accounting policies, judgments and estimates (Continued)

(Note 12). The classification of leases depends on the substance of the transaction and not on the form of the contract.

Assets acquired under finance leases and the corresponding liability to the lessor are accounted for using the finance method, in accordance with the lease payment plan (Note 38). Interest included in the rents and the depreciation of the assets are recognised in net income in the period they occur.

Under operating leases, rents are recognised on a straight-line basis during the period of the lease (Note 12).

o) Taxation

Income tax expense is recognised in accordance with IAS 12 Income Taxes (''IAS 12'') and represents the sum of the tax currently payable and deferred tax.

Portugal Telecom has adopted the tax consolidation regime in Portugal (currently known as the special regime for the taxation of groups of companies). The provision for income taxes is determined on the basis of the estimated taxable income for all the companies in which Portugal Telecom holds at least 90% of the share capital and that are domiciled in Portugal and subject to Corporate Income Tax (IRC). The remaining Group companies not covered by the tax consolidation regime of Portugal Telecom are taxed individually based on their respective taxable income, at the applicable tax rates.

The current tax payable is based on taxable income for the period, and deferred taxes are based on differences between the carrying amounts of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit, and are accounted for using the liability method.

Deferred tax liabilities are generally recognised for all taxable temporary differences, and deferred tax assets are recognised to the extent that it is reasonably likely that taxable income will be available against which deductible temporary differences can be used, or when there are deferred tax liabilities the reversal of which is expected in the same period in which the deferred tax assets reverse. The carrying amount of deferred tax assets is reviewed at the date of the Consolidated Statement of Financial Position and is reduced to the extent that it is no longer probable that sufficient taxable income will be available to allow for all or part of the asset to be recovered.

Deferred tax is charged to net income, except when it relates to items charged or credited directly to shareholders' equity, in which case the deferred tax is also recognised directly in shareholders' equity. Accordingly, the impact of changes in tax rate is also charged to net income, except when it relates to items charged or credited directly to shareholders' equity, in which case that impact is also recognised directly in shareholders' equity.

3. Significant accounting policies, judgments and estimates (Continued)

p) Revenue recognition

Revenues from fixed line telecommunications are recognised at their gross amounts when services are rendered. Billings for these services are made on a monthly basis throughout the month. Unbilled revenues or revenues not billed by other operators but accrued or incurred as of the date of the financial statements are recorded based on estimates. Differences between accrued amounts and the actual unbilled revenues, which ordinarily are not significant, are recognised in the following period.

Revenues from international telecommunications services are divided with the operators of the transit countries and the operators of the country in which calls are terminated based on traffic records of the country of origin and rates established in agreements with the various telecommunications operators. The operator of the country of origin of the traffic is responsible for crediting the operator of the destination country and, if applicable, the operators of the transit countries.

Revenues from rentals of terminal equipment are recognised as an operating lease in the period to which they apply, under operating revenues.

Revenues from Internet Service Providers (''ISP'') services result essentially from monthly subscription fees and telephone traffic when the service is used by customers. These revenues are recognised when the service is rendered.

Revenues from Pay-TV services result essentially from and are recognised as follows:

Nature of the revenue	Caption	Moment of recognition
Monthly subscription fees for the use of the service	Services rendered	When the service is rendered
Rental of equipment	Services rendered	The period of rental
Sale of equipment	Sales	When the sale occurs
Penalties imposed to customers	Other revenues	When received

Revenues from mobile telephony services result essentially from the use of the wireless network, by customers or other operators. The moment in which revenues are recognised and the corresponding caption are as follows:

Nature of the revenue	Caption	Moment of recognition
Use of the network	Services rendered	In the month the service is rendered
Interconnection fees	Services rendered	In the month the service is rendered
Roaming	Services rendered	In the month the service is rendered
Pre-paid cards	Services rendered	When the service is rendered
Wireless broadband	Services rendered	When the service is rendered
Terminal equipment and accessories	Sales	When the sale occurs
Penalties imposed to customers	Other revenues	When received

Revenues from bundling services or products are allocated to each of its components based on its fair value and are recognised separately in accordance with the methodology adopted to each component.

3. Significant accounting policies, judgments and estimates (Continued)

The Group operates loyalty programmes for some of its customers, under which, based on certain levels of mobile traffic, these customers receive loyalty points that can be exchanged for equipments, accessories and discounts on subsequent purchases of telecommunications services. Portugal Telecom splits the consideration received in the initial transaction between the revenue related to traffic and the loyalty points earned by the customer, recognizing a deferred income measured at fair value for the award credits, taking into consideration the expected points to be redeemed. Deferred income is then recognized as revenue when award credits are redeemed or expire.

q) Foreign currency transactions and balances

Transactions denominated in foreign currencies are translated to Euros at the exchange rates prevailing at the time the transactions are made. At the date of the Consolidated Statement of Financial Position, assets and liabilities denominated in foreign currencies are adjusted to reflect the exchange rates prevailing at such date. The resulting gains or losses on foreign exchange transactions are recognised in net income. Exchange differences on non-monetary items, including goodwill, and on monetary items representing an extension of the related investment and where settlement is not expected in the foreseeable future, are recognized directly in shareholders' equity under the caption ''Cumulative foreign currency translation adjustments'', and included in the Consolidated Statement of Comprehensive Income.

The financial statements of subsidiaries operating in other countries are translated to Euros, using the following exchange rates:

• Assets and liabilities at exchange rates prevailing at the date of the Consolidated Statement of Financial Position;
• Profit and loss items at average exchange rates for the reported period;
• Cash flow items at average exchange rates for the reported period, where these rates approximate the effective exchange rates (and in the remaining cases, at the rate effective on the day the transaction occurred); and
• Share capital, reserves and retained earnings at historical exchange rates.

The effect of translation differences is recognised in shareholders' equity under the caption ''Cumulative foreign currency translation adjustments'' and is included in the Consolidated Statement of Comprehensive Income. In accordance with IAS 21, when a reduction of Portugal Telecom's investment in a foreign entity occurs, through the sale or reimbursement of share capital, the accumulated effect of translated differences is transferred to the Consolidated Income Statement, considering the proportion of the reduction occurred.

The Group adopted the exception under IFRS 1 relating to cumulative translation adjustments as of 1 January 2004 and transferred this amount from ''Foreign currency translation adjustments'' to ''Accumulated earnings''. As from 1 January 2004, the Group has been recognizing all translation adjustments directly in shareholders' equity and therefore these amounts are transferred to net income

3. Significant accounting policies, judgments and estimates (Continued)

only if and when the related investments are disposed off or there is a repayment of the investment made.

r) Borrowing costs

Borrowing costs related to loans are recognised in net income when incurred. The Group does not capitalise any borrowing costs related to loans to finance the acquisition, construction or production of any asset, where the construction period of its tangible and intangible assets is relatively short.

s) Consolidated Statement of Cash Flows

The Consolidated Statement of Cash Flows is prepared under IAS 7, using the direct method. The Group classifies all highly liquid investments, with original maturity of up to three months and an insignificant risk of change in fair value, as ''Cash and cash equivalents''. The ''Cash and cash equivalents'' item presented in the Consolidated Statement of Cash Flows also includes overdrafts, classified in the Consolidated Statement of Financial Position under ''Short-term debt''.

Cash flows are classified in the Consolidated Statement of Cash Flows according to three main categories, depending on their nature: (1) operating activities; (2) investing activities; and (3) financing activities. Cash flows from operating activities include primarily collections from clients, payments to suppliers, payments to employees, payments relating to post retirement benefits and net payments relating to income taxes and indirect taxes. Cash flows from investing activities include primarily acquisitions and disposals of investments, dividends received from associated companies and purchase and sale of property, plant and equipment. Cash flows from financing activities include primarily borrowings and repayments of debt, payments relating to interest and related expenses, acquisition and sale of treasury shares and payments of dividends to shareholders.

t) Subsequent events (Note 50)

Events that occur after the date of the Consolidated Statement of Financial Position that could influence the value of any asset or liability as of that date are considered when preparing the financial statements for the period. Those events are disclosed in the notes to the financial statements, if material.

Critical judgments and estimates

The preparation of the consolidated financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the application of policies and reported amounts. Estimates and judgements are continually evaluated and are based on historical experience and other factors including expectations of future events that are believed to be reasonable under the circumstances on which the estimate was based, or as a result of new information or more experience.

3. Significant accounting policies, judgments and estimates (Continued)

The main accounting judgments and estimates reflected in the consolidated financial statements are as follows:

• (a) Post retirement benefits—The present value of post retirement obligations is computed based on actuarial methodologies, which use certain actuarial assumptions. Any changes in those assumptions will impact the carrying amount of post retirement obligations. The key assumptions for post retirement obligations are disclosed in Note 14. The Company has the policy to review key assumptions on a periodic basis, if the corresponding changes have a material impact on the financial statements.
• (b) Goodwill impairment analysis—Portugal Telecom tests annually whether goodwill has suffered any impairment. The recoverable amounts of cash-generating units have been determined based on value-in-use calculations. The use of this method requires the estimate of future cash flows expected to arise from the continuing operation of the cash generating unit, the choice of a growth rate to extrapolate cash flow projections and the estimate of a suitable discount rate for each cash generating unit.
• (c) Valuation and useful life of intangible and tangible assets—Portugal Telecom has made assumptions in relation to the potential future cash flows resulting from separable intangible assets acquired as part of business combinations, which include expected future revenues, discount rates and useful life of such assets. Portugal Telecom has also made assumptions regarding the useful life of tangible assets.
• (d) Recognition of provisions and adjustments—Portugal Telecom is party to various legal claims for which, based on the opinion of its legal advisors, a judgment was made to determine whether a provision should be recorded for these contingencies (Note 49). Adjustments for accounts receivable are computed based primarily on the aging of the receivables, the risk profile of the customer and its financial condition. These estimates related to adjustments for accounts receivable differ from business to business.
• (e) Assessment of the fair value of financial instruments—Portugal Telecom chooses an appropriate valuation technique for financial instruments not quoted in an active market based on its best knowledge of the market and the assets. In this process, Portugal Telecom applies the valuation techniques commonly used by market practitioners and uses assumptions based on market rates.
• (f) Assessment of the fair value of revalued assets—Portugal Telecom uses the revaluation model to measure the carrying value of certain tangible asset classes. In order to determine the revalued amount of those assets, Portugal Telecom uses the replacement cost method for the ducts infra-structure and the market value for real estate assets, which require the use of certain assumptions related to the construction cost and the use of specific indicators for the real estate market, respectively, as explained in more detail in Note 37.

3. Significant accounting policies, judgments and estimates (Continued)

(g) Deferred taxes—The Group recognizes and settles income taxes based on the results of operations determined in accordance with the local corporate legislation, taking into consideration the provisions of the tax law, which are materially different from the amounts calculated for IFRS purposes. In accordance with IAS 12, the Company recognizes deferred tax assets and liabilities based on the differences between the carrying amounts and the taxable bases of the assets and liabilities. The Company regularly assesses the recoverability of deferred tax assets and recognizes an allowance for impairment losses when it is probable that these assets may not be realized, based on the history of taxable income, the projection of future taxable income, and the time estimated for the reversal of existing temporary differences. These calculations require the use of estimates and assumptions. The use of different estimates and assumptions could result in the recognition of an allowance for impairment losses for the entire or a significant portion of the deferred tax assets.

Estimates used are based on the best information available during the preparation of the consolidated financial statements, although future events, neither controlled nor foreseeable by the Company, could occur and have an impact on those estimates. In accordance with IAS 8, changes to the estimates used by management that occur after the date of the consolidated financial statements are recognised in net income, using a prospective methodology.

4. Changes in accounting policies and estimates

During the year ended 31 December 2011, the following standards, revised standards or interpretations became effective, although their adoption had no material effect on Portugal Telecom's financial statements:

• Amendments to IAS 24 Related Party Disclosures;
• Amendments to IFRIC 14 The Limit on a Defined Benefit Asset, Minimum Funding Requirements and their Interaction;
• IFRIC 19 Extinguishing Financial Liabilities with Equity Instruments;
• Amendments to IFRS 1 First Time Adoption of IFRS;
• Amendments to IAS 32 Financial Instruments;
• Amendments to IFRS 7 Financial Instruments: Disclosures; and
• Amendments to IAS 1 Presentation of Financial Statements and IFRS 3 Business Combinations as part of a document issued in 2010 related to minor improvements across several standards.

In 2011, 2010 and 2009 the International Accounting Standards Board (''IASB'') issued the following new standards, which were not yet adopted by Portugal Telecom as they were not yet endorsed by the European Union and their application is only required in subsequent periods:

• On 16 June 2011, the IASB issued amendments to IAS 19 Employee Benefits, which include primarily: (i) the elimination of an option to defer the recognition of actuarial gains and losses, known as the 'corridor method'; (ii) streamlining the presentation of changes in assets and

4. Changes in accounting policies and estimates (Continued)

liabilities arising from defined benefit plans, including requiring remeasurements to be presented in other comprehensive income, thereby separating those changes from changes that many perceive to be the result of an entity's day-to-day operations; and (iii) enhancing the disclosure requirements for defined benefit plans, providing better information about the characteristics of defined benefit plans and the risks that entities are exposed to when participating in those plans. This standard is effective for annual periods beginning on or after 1 January 2013. The Company is accessing the impacts resulting from the adoption of this revised standard, although it should be mentioned that Portugal Telecom already recognizes actuarial gains and losses directly in shareholders' equity;

• On 16 June 2011, the IASB issued amendments to IAS 1 Presentation of Financial Statements that require additional disclosures to be made in the statement of comprehensive income such that items of other comprehensive income are grouped into two categories: (a) items that will not be reclassified subsequently to profit or loss; and (b) items that will be reclassified subsequently to profit or loss when specific conditions are met. These amendments to IAS 1 are effective for annual periods beginning on or after 1 July 2012;
• On 12 May 2011, the IASB issued IFRS 10 Consolidated Financial Statements, which establishes the principles for the presentation and preparation of consolidated financial statements when an entity controls one or more entities. IFRS 10 builds on existing principles by identifying the concept of control as the determining factor in whether an entity should be included within the consolidated financial statements of the parent company. The standard provides additional guidance to assist in the determination of control where this is difficult to assess. IFRS 10 replaces the consolidation requirements in SIC 12 Consolidation—Special Purpose Entities and IAS 27 Consolidated and Separate Financial Statements. The Company is accessing the impacts of the adoption of this standard, which is effective for annual periods beginning on or after 1 January 2013;
• On 12 May 2011, the IASB issued IFRS 11 Joint Arrangements, which classifies joint arrangements as either joint operations (combining the existing concepts of jointly controlled assets and jointly controlled operations) or joint ventures (equivalent to the existing concept of a jointly controlled entity) and requires the use of the equity method of accounting for interests in joint ventures thereby eliminating the proportionate consolidation method. This standard, which supersedes IAS 31 Interest in Joint Ventures and SIC 13 Jointly Controlled Entities—Non-Monetary Contributions by Ventures, is effective for annual periods beginning on or after 1 January 2013. Upon the adoption of this new standard, Portugal Telecom will not be able to proportionally consolidate its investments in Oi, Contax and its controlling shareholders;
• On 12 May 2011, the IASB issued IFRS 12 Disclosure of Interests in Other Entities, which is applicable to entities that have an interest in subsidiaries, joint arrangements, associates or unconsolidated structured entities, establishes disclosure objectives and specifies minimum disclosures that an entity must provide to meet those objectives. In accordance with this standard, an entity should disclose information that helps users of its financial statements to evaluate the nature of and risks associated with its interests in other entities and the effects of

4. Changes in accounting policies and estimates (Continued)

those interests on its financial statements. The Company is accessing the impacts of the adoption of this standard, which is effective for annual periods beginning on or after 1 January 2013;

• On 12 May 2011, the IASB issued IFRS 13 Fair Value Measurement, which establishes a single source of guidance for fair value measurement under IFRS. Fair value is defined as ''the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date''. The Company is accessing the impacts of the adoption of this standard, which is effective for annual periods beginning on or after 1 January 2013;
• Following the above mentioned standards issued on 12 May 2011, the standards IAS 27 Consolidated and Separate Financial Statements and IAS 28 Investments in Associates were revised accordingly;
• On 20 December 2010, the IASB issued amendments to IAS 12 Income Taxes which provide an exception to the general principles in IAS 12 that the measurement of deferred tax assets and deferred tax liabilities should reflect the tax consequences that would follow from the manner in which the entity expects to recover the carrying amount of an asset. Specifically, under the amendments, investment properties that are measured using the fair value model in accordance with IAS 40 Investment Property are presumed to be recovered through sale for the purposes of measuring deferred taxes, unless the presumption is rebutted in certain circumstances. The Company is accessing the impacts of the adoption of these amendments to IAS 12, which are effective for annual periods beginning on or after 1 January 2012;
• On 7 October 2010, the IASB issued amendments to IFRS 7 Financial Instruments: Disclosures that increase the disclosure requirements for transactions involving transfers of financial assets. These amendments are intended to provide greater transparency around risk exposures when a financial asset is transferred but the transferor retains some level of continuing exposure in the asset. These amendments are effective for annual periods beginning on or after 1 July 2011;
• In November 2009, the IASB issued IFRS 9 Financial Instruments, which introduces new requirements for the classification and measurement of financial assets. Subsequently, in October 2010, IFRS 9 was amended to include the requirements for the classification and measurement of financial liabilities and for derecognition. The Company is accessing the impacts of the adoption of this standard, which is effective for annual periods beginning on or after 1 January 2013.

⁽i) For information on this operating segment performance, including explanations for changes in operating revenues, see Note 7.a).

• (ii) As mentioned in Note 2, the results of Oi were proportionally consolidated as from 1 April 2011. For information on this operating segment performance, see Note 7.b).
• (iii) In 2011, the increase in the contribution of other businesses to consolidated revenues relates mainly to (1) the impact of the proportional consolidation of Contax as from 1 April 2011 (Euro 359 million) and (2) improved revenue performance of MTC (mobile operator in Namibia) and Timor Telecom. These effects were partially offset by a lower contribution from Dedic/GPTI, as this business was fully consolidated until 30 June 2011 and then integrated in Contax. In 2010, the increase in revenues relating to other businesses is primarily explained by improved revenue performance of Dedic, MTC and Timor Telecom, and also includes the impact of the consolidation of GPTI as from 1 March 2010 (Euro 56 million).

Revenue is recognized in accordance with principles referred to in Note 3.p). Services rendered caption includes mainly revenue derived from (1) fixed line and international telecommunications services, including billed and interconnection revenues, (2) Pay-TV services, including monthly subscription fees and rental of equipment, (3) mobile telecommunications services, including usage of network, interconnection fees, roaming, pre-paid cards and wireless broadband, and (4) advertising in directories. Sales correspond mainly to the disposals of terminal equipment, including fixed telephones, modems, TV boxes and terminal mobile equipment. Other revenues include mainly Portal's advertising revenues, benefits from contractual penalties imposed to customers, rental of equipments and other own infra-structures and revenues resulting from consultancy projects.

(i) In 2011, this caption includes revenues from Oi and Contax totalling Euro 2,768 million, which were proportionally consolidated as from 1 April 2011, as explained above.

7. Segment reporting

Following the acquisition of a 25.3% stake in Oi and the proportionally consolidation of its results as from 1 April 2011, Portugal Telecom discloses Oi as an operating segment since the Company's management currently reviews and assesses its performance periodically. This operating segment, named ''Telecommunications in Brazil—Oi'', includes the holding company TNL and Telemar Norte Leste and its subsidiaries.

Up to 30 June 2011, Portugal Telecom's operating segments in Portugal, which were organized based on the type of technology used to provide its services and products to customers, included the Wireline (fixed telecommunication services rendered through PT Comunica¸coes and PT Prime) and ˜ Mobile (mobile telecommunication services rendered through TMN) operating segments. Following the progressive integration of the fixed line and mobile services and the launch of new bundle products offered to its customers, the Board of Directors of Portugal Telecom changed, as from that date, the way it reviews and assesses the performance of its businesses in Portugal, and therefore changed the disclosure of its operating segments in Portugal, replacing the former operating segments ''Wireline in Portugal'' and ''Mobile in Portugal'' for one operating segment named ''Telecommunications in Portugal'', which includes all telecommunications services in Portugal. Following this change, the corresponding financial information for previous years was restated.

As a result of the changes mentioned above, the operating segments as at 31 December 2011 are as follows: (i) Telecommunications in Portugal; and (ii) Telecommunications in Brazil—Oi. There is no difference between operating and reportable segments.

In addition to the above mentioned reportable segments, the Group has other businesses that do not comply individually or together with any of the quantitive thresholds that would require a disclosure as a reportable segment. These businesses relate primarily to the following Goup companies: (1) Contax, which renders BPO and contact centre services; (2) MTC, Cabo Verde Telecom and Timor Telecom, which render wireline and mobile telecommunications services; and (3) certain Portuguese support companies, namely PT—Sistemas de Informa¸cao, Portugal Telecom Inova¸ ˜ cao, PT Pro Servi¸ ˜ cos Administrativos e de Gestao Partillhados and PT Contact—Telemarketing e Servi¸ ˜ cos de Informa¸cao. ˜

Income before financial results and taxes	498,354,864	415,090,877	674,555,895

⁽i) The reduction in total revenues in 2011 is primarily explained by: (1) a revenue decline in the Personal customer segment (Euro 97 million), from Euro 865 million in 2010 to Euro 768 million in 2011, including lower mobile interconnection revenues (Euro 29 million), mainly as a result of the negative impact of lower Mobile Termination Rates (''MTRs''), lower customer service revenues (Euro 55 million) that reflect challenging economic conditions in Portugal, including a VAT increase (+3pp in the first half of 2011 and +2pp in the second half of 2011), coupled with increasing popularity of tribal plans, and lower sales; (2) lower revenues driven by the Enterprise customer segment (Euro 97 million), from Euro 1,080 million in 2010 to Euro 982 million in 2011, penalized by the economic environment and consequent cost cutting efforts from companies and also by a one-off public schools project that took place in 2010; and (3) lower revenues from wholesale and other businesses (Euro 74 million), from Euro 533 million in 2010 to

7. Segment reporting (Continued)

Euro 459 million in 2011, including the impact from the decline in the directories business (Euro 20 million). These effects were partially offset by an increase in revenues from the Residential customer segment (Euro 35 million), from Euro 647 million in 2010 to Euro 682 million in 2011, mainly related to Pay-TV and broadband revenues, which are underpinned by the success of Meo's double and triple play offers. In 2010, the reduction in total revenues, as compared to the year 2009, is primarily explained by: (1) a revenue decline in the Personal customer segment, including lower mobile interconnection revenues, mainly as a result of the negative impact of lower Mobile Termination Rates (''MTRs''), lower customer service revenues that reflect increased competitiveness in certain market segments, especially in the youth segment, and challenging economic conditions in Portugal, and lower sales; (2) lower revenues driven by the Enterprise customer segment, penalized by the economic environment; and (3) lower revenues from wholesale and other businesses, including the impact from the decline in the directories business. These effects were partially offset by an increase in revenues from the Residential customer segment, mainly related to Pay-TV and broadband revenues, which are underpinned by the success of Meo's double and triple play offers.

• (ii) The decrease in direct costs in 2011 is primarily explained by a reduction in interconnection costs, mainly due to the decrease in regulated MTRs, and the decline in the directories business, which more than offset higher programming costs due to the continued growth of pay-TV customers, notwithstanding a decline in programming costs per customer as pay-TV is reaching critical mass.
• (iii) This caption includes costs of products sold, commissions and marketing and publicity expenses. The reductions in 2011 and 2010 are primarily explained by a decrease in costs of products sold, due to the racionalization of TMN's handset portfolin and lower equipment sales.
• (iv) In 2011, the reduction in this caption resulted primarily from lower maintenance and repair expenses, as a result of the rollout of Portugal Telecom's FTTH network, which is more efficient, and also from several cost cutting initiatives undertaken at Portuguese operations.
• (v) The increase in depreciation and amortization costs in 2011 and 2010 relates mainly to the investments made in the roll-out of the pay-tv service, which in 2011 more than offset the reduction related to the swap of TMN's 2G equipment for LTE (4G) enabled equipment.
• (vi) As explained in more detail in Note 14, the increase in this caption in 2010 reflects primarily a prior year service gain recorded in 2010, amounting to Euro 31 million, related to changes introduced in the pension formula by Law 3-B/2010, which more than offset the positive impact of the transfer to the Portuguese State of unfunded pension liabilities. The reduction in 2010, as compared to 2009, is basically explained by the above mentioned prior year service gain recognised in 2010.
• (vii) In 2010, this caption includes primarily redundancy programme costs amounting to Euro 136 million, related to a redundancy programme approved by the year end (Note 14.5), and a cost of Euro 7.5 million related to the settlement of the defined benefit plans transferred to the Portuguese State in December 2010.

7. Segment reporting (Continued)

(viii) Other costs in 2010, as mentioned in Note 15, include non-recurring provisions and adjustments that were recognized in order to adjust certain receivables and inventories to their recoverable amounts and reflect estimated losses with certain legal actions.

In the years ended 31 December 2011, 2010 and 2009, capital expenditures in tangible and intangible assets for this reportable segment amounted to Euro 647 million, Euro 657 million and Euro 745 million, respectively. The reduction in 2011 reflected a decline in capital expenditures from residential customer segment due to a decrease in customer related capital expenditures as a result of: (1) a lower number of set-top boxes per fibre TV customer as compared to ADSL; (2) lower unitary cost of set-top boxes, optical network terminators and home gateways, and (3) improved refurbishment rates of set-top boxes. These effects were partially offset by an increase in capital expenditures related to the mobile network, explained by investments in the swap of TMN's 2G equipments for LTE (4G) enabled equipments and investments in capacity of existing 3G and 3.5G networks, namely in urban areas. Additionally, Portugal Telecom has been strengthening its mobile data capabilities and its network quality by leveraging the existing FTTH deployment to boost its mobile network quality and lead the 4G roll-out in the Portuguese market. The decrease of capital expenditures in 2010, as compared to 2009, reflected primarly (1) lower infrastructure-related capital expenditures following the significant efforts in the FTTH coverage undertaken in 2009, (2) lower investment in legacy infrastructure, following the FTTH rollout, and (3) the focus on cash-flow generation, supported by synergies from fixed-mobile integration. In addition to the above mentioned capital expenditures, this business segment incurred in one-off capital expenditures totalling to Euro 136 million in 2011 and Euro 227 million in 2010, as mentioned in Notes 36 and 37, and also Euro 12 million in 2009 related to additional commitments under the terms of the UTMS license.

As at 31 December 2011 and 2010, the total staff in this segment was 7,535 and 7,206 employees, respectively.

Oi's capital expenditures in tangible and intangible assets for the nine months period between 1 April and 31 December 2011 amounted to Euro 444 million. The investments were directed primarily to projects to improve fixed network quality, expand coverage of fixed and mobile networks, increase the speed of fixed broadband services, increase the capacity of 3G data traffic in strategic locations and to provide data packages to corporate clients.

As at 31 December 2011, the total staff in this segment (considering the 25.6% stake used in the proportional consolidation) was 7,892 employees, as compared to 7,343 employees as at 31 March 2011.

c) Reconciliation of revenues and net income and information by geographic area

In 2011, 2010 and 2009, the reconciliation between revenues of reportable segments and consolidated revenues is as follows:

	2011	2010 Euro	2009
Revenues relating to reportable
segments	5,304,115,708	3,124,455,165	3,273,093,312
Revenues relating to other
businesses(i)	1,441,145,339	1,088,297,486	873,863,680
Elimination of intragroup revenues(i)	(598,416,326)	(470,498,813)	(413,552,188)
Total consolidated revenues	6,146,844,721	3,742,253,838	3,733,404,804

(i) As mentioned above, other businesses include primarily Contax, MTC, Cabo Verde Telecom, Timor Telecom and certain Portuguese support companies, the performance of which is monitored by the management on a standalone basis. The increase in revenues relating to other business in the year ended 31 December 2011 relates mainly to (1) the impact of the proportional consolidation of Contax as from 1 April 2011 (Euro 469 million) and (2) improved revenue performance of MTC and Timor Telecom. These effects were partially offset by a lower contribution from Dedic/GPTI (Euro 128 million), as this business was fully consolidated only until 30 June 2011 and then integrated in Contax. The increase in revenues relating to other business in 2010, as compared to 2009, is primarly explained by the consolidation of GPTI as from 1 March 2010 (Euro 56 million), as mentioned above. The higher level of eliminations in 2011, as compared to 2010, is primarily explained by the elimination of call centre and other corporate services rendered by Contax to Oi, as these companies were proportionally consolidated as from 1 April 2011.

7. Segment reporting (Continued)

In the years ended 31 December 2011, 2010 and 2009, the reconciliation between net income before financial results and taxes of reportable segments and Group's consolidated net income is as follows:

Net income (before non-controlling interests)	422,911,743	5,820,066,802	789,186,176

⁽i) The losses recorded in 2010 under this caption relate mainly to expenses incurred in the third quarter, amounting to Euro 25 million, in connection with the acquisition of the investments in Oi and Contax, as mentioned in Note 15. Adjusting for this effect, the decrease in this caption in 2011 is primarly explained by a lower contribution from Dedic/GPTI business, which was fully consolidated only until 30 June 2011 and then integrated in Contax, which more than offset the improvement in the earnings of certain international operations, namely MTC and Timor Telecom, and the impact of the proportional consolidation of Contax as from 1 April 2011.

7. Segment reporting (Continued)

Total assets, liabilities and tangible and intangible assets by geographic area as at 31 December 2011 and 2010 and capital expenditures for tangible and intangible assets in the years ended 31 December 2011 and 2010 are as follows:

			2011

(i) The decrease in total assets from operations in Portugal is primarily explained by the amount paid for the acquisition of the investments in Oi and Contax (Euro 3,728 million), partially offset by several financing loans entered into in 2011 which led to an increase in both total assets and liabilities.

• (ii) The higher contribution from Brazilian businesses across all captions is basically explained by the contribution of Oi, Contax and its controlling shareholders, which are proportionally consolidated in Portugal Telecom's financial statements since 31 March 2011.
• (iii) Total capital expenditures in 2011 and 2010 include capital expenditures for tangible assets, amounting to Euro 1,049 million and Euro 692 million (Note 37), respectively, and capital expenditures for intangible assets amounting to Euro 175 million and Euro 106 million (Note 36), respectively. In addition to these amounts, the Group recognized certain one-off capital expenditures in tangible and intangible assets, as mentioned in Notes 37 and 36.

8. Wages and salaries

The composition of this caption in the years ended 31 December 2011, 2010 and 2009 is as follows:

	2011	2010	2009
		Euro
Salaries	771,408,966	507,131,463	439,911,127
Social security	174,072,680	101,981,635	81,050,952

	1,020,475,455	637,115,622	546,689,537

(i) In 2011, this caption includes mainly costs from Oi and Contax related to transportation expenses and personnel selection and recruitment expenses.

In 2011, the increase in total consolidated wages and salaries is primarily explained by the impact of the proportional consolidation of Oi and Contax as from 1 April 2011, amounting to Euro 505 million (Note 2.b), partially offset by lower contributions from: (1) the operating segment ''Telecommunications in Portugal'' (Euro 23 million—Note 7.a), reflecting primarily lower variable and overtime remunerations, higher efficiency levels in certain internal processes and lower personnel costs as a result of the restructuring plan implemented in the end of 2010; and (2) Dedic/GPTI (Euro 78 million), as this business was fully consolidated only until 30 June 2011 and then integrated in Contax. In 2010, the increase in wages and salaries is primarily explained by higher contributions from Dedic and from GPTI, which was consolidated as from 1 March 2010.

9. Direct costs

The composition of this caption in the years ended 31 December 2011, 2010 and 2009 is as follows:

(i) In 2011, 2010 and 2009, these captions include costs related to operating leases totalling Euro 92,317,816, Euro 44,538,490 and Euro 40,500,541, respectively (Note 12).

9. Direct costs (Continued)

• (ii) This caption relates basically to the programming costs incurred by the Pay-TV operation.
• (iii) The reduction in this caption is directly related to the decline of the directories business.
• (iv) This caption includes primarily mobile contents and the increase occurred in 2011 relates primarily to the proportional consolidation of Oi as from 1 April 2011.

In 2011, the increase in total consolidated direct costs is primarily explained by the impact of the proportional consolidation of Oi as from 1 April 2011, amounting to Euro 521 million (Note 2.b), partially offset by a lower contribution from the operating segment ''Telecommunications in Portugal'' (Euro 55 million), as a result of a decrease in interconnection costs, due to lower Mobile Termination Rates (''MTRs''), and the decline in the directories business.

10. Costs of products sold

The composition of this caption in the years ended 31 December 2011, 2010 and 2009 is as follows:

	2011	2010	2009
		Euro
Costs of products sold	175,720,765	180,819,046	203,507,171

	169,875,122	179,893,915	207,256,041

The decreases in total consolidated costs of products sold in 2011 and 2010 reflect mainly a lower contribution from the operating segment ''Telecommunications in Portugal'' (Euro 38 million and Euro 46 million, respectively) in line with the decline in sales occurred in those years, which in 2011more than offset the impact of the proportional consolidation of Oi as from 1 April, amounting to Euro 32 million (Note 2.b).

11. Supplies, external services and other expenses

The composition of this caption in the years ended 31 December 2011, 2010 and 2009 is as follows:

	1,281,382,721	724,519,676	733,310,901

The increase in total consolidated supplies, external services and other expenses in 2011 is primarily explained by the impact of the proportional consolidation of Oi and Contax as from 1 April 2011, amounting to Euro 597 million (Note 2.b), partially offset by a reduction in the operating segment ''Telecommunications in Portugal'' (Euro 48 million), reflecting the strict operational and cost discipline on external supplies, and a lower contribution from Dedic/GPTI (Euro 21 million, which was fully consolidated only until 30 June 2011 and then integrated in Contax.

12. Operating leases

In the years ended 31 December 2011, 2010 and 2009, operating lease costs were recognised under the following captions:

(i) This caption includes primarily spectrum fees from Oi's mobile operations (Euro 53 million in 2011) and TMN (Euro 17 million in 2011, Euro 21 million in 2010 and Euro 24 million in 2009).

(ii) The increase in this caption in 2011 relates primarily to the proportional consolidation of Oi as from 1 April 2011, amounting to Euro 91 million, including mainly (1) indirect taxes related to the funds ''Fust'' (fund to improve the general access to telecommunications services) and ''Funtel'' (National Telecommunications Fund), totalling Euro 29 million, (2) Value Added Tax expenses (Euro 13 million), (3) concessions fees (Euro 9 million), and (4) other municipal, federal and state taxes in Brasil.

The increase in total consolidated indirect taxes in 2011 is primarily explained by the impact of the proportional consolidation of Oi, Contax and its controlling shareholders as from 1 April 2011, totalling Euro 146 million (Note 2.b).

14. Post retirement benefits

14.1. Portuguese Operations

As referred to in Note 3, PT Comunica¸coes and PT SI sponsor defined benefit plans under which ˜ grant pension supplements to retired and active employees, healthcare services after retirement age and

14. Post retirement benefits (Continued)

salaries to suspend and pre-retired employees until retirement age. Prior to the transfer of unfunded pension obligations to the Portuguese State in 2010, PT Comunica¸coes was also responsible for the ˜ payment of pensions under the referred plans.

On 2 December 2010, Portugal Telecom reached an agreement with the Portuguese State for the transfer to Caixa Geral de Aposenta¸coes of the Pension Plans that were sponsored by PT ˜ Comunica¸coes and the associated funds that covered such liabilities. The transfer included the ''Plano ˜ de Pensoes do Pessoal da Portugal Telecom/CGA'', the ''Plano de Pens ˜ oes Regulamentares da ˜ Companhia Portuguesa Radio Marconi'' and the liabilities associated with the survival benefit included ´ in the ''Plano de Pensoes Marconi'' (together the ''Regulated Pension Plans''). The transfer date of the ˜ ''Plano de Pensoes do Pessoal da Portugal Telecom/CGA'' was 1 December 2010 and for the ''Plano de ˜ Pensoes Regulamentares da Companhia Portuguesa R ˜ adio Marconi'' and ''Plano de Pens ´ oes Marconi'' ˜ was 31 December 2010.

The present value of past liabilities of the Regulated Pension Plans, as of the date of transfer, amounted to Euro 2,804 million (Note 14.1.1) and was determined by an independent actuary using actuarial assumptions that comply with best practices of similar transactions. The market value of the pension funds as of the delivery dates amounted to Euro 1,782 million (Note 14.1.1). Accordingly, the unfunded transferred liabilities amounted to Euro 1,022 million, of which an amount of Euro 100 million was paid in December 2010 (Note 14.4). As mentioned in Note 38.8, from the outstanding amount of Euro 922 million as at 31 December 2010, Portugal Telecom settled Euro 17.4 million in January 2011 and Euro 450.0 million in December 2011, and the remainder consideration of Euro 454.3 million shall be paid no later than 20 December 2012.

The book value of the transferred pension liabilities computed in accordance with Portugal Telecom's actuarial assumptions amounted to Euro 2,796 million, as compared to the amount of Euro 2,804 million computed by an independent actuary used in this transaction. The difference amounting to Euro 7.5 million was recorded as a settlement cost (Note 14.1.1).

Following the transfer of the Regulated Pension Plans to the Portuguese State, PT Comunica¸coes ˜ is now responsible for a fixed monthly contribution to Social Security and CGA in order to fund future service of the active beneficiaries included in these plans.

14. Post retirement benefits (Continued)

The actuarial valuations of Portugal Telecom's defined benefit plans related to Portuguese operations as at 31 December 2011, 2010 and 2009 were computed based on the projected unit credit method and considered the following main financial and demographic actuarial assumptions:

	2011	2010	2009

Disability table (Swiss Reinsurance
Company)	25%	25%	100%
Active employees with spouses under
the plan .	35%	35%	50%
Turnover of employees	Nil	Nil	Nil

(i) For salaries payable between 2012 and 2016, the salary growth rate ranges from 0% to 1% depending on the amount of the salary. As from 2017, the salary growth rate is 1.75% for all situations.

The changes in actuarial assumptions were primarily due to changes occurred in market conditions.

The discount rate was computed based on long-term yield rates of high-rating bonds as of the date of the Consolidated Statement of Financial Position for durations comparable to the liabilities for pensions and pension supplements, salaries and health care benefits (between 4 and 13 years).

14. Post retirement benefits (Continued)

The rate of return on long-term fund assets was estimated based on historical information on the return of portfolio assets, the expected portfolio in future years (defined in accordance with the expected maturity of the liabilities) and certain financial market performance indicators usually considered in market analysis.

Salary growth rate was established in accordance with Group policy for wages and salaries and pension growth rate and the sustainability factor was established in line with Portuguese Government information.

Demographic assumptions considered by Portugal Telecom are based on mortality tables generally accepted for actuarial valuation purposes, with these tables being periodically adjusted to reflect the mortality experience occurred in the closed universe of the plan participants.

In the years ended 31 December 2011 and 2010, the total impact of changes in actuarial assumptions was a net gain of Euro 19,426,453 and a net loss of Euro 441,787,345 (Note 14.6), respectively, and was recognized directly in the Consolidated Statement of Comprehensive Income.

The impact of an increase by 25 bp on the average discount rate actuarial assumption would be a decrease of the responsibilities for post retirement benefits by approximately Euro 21 million as at 31 December 2011, while the impact of an increase (decrease) in the health care cost trend rate by 1% would be an increase (decrease) of the responsibilities for post retirement benefits by approximately Euro 61 million (Euro 50 million) as at 31 December 2011.

The impact of an increase (decrease) by 1% in the rate of return on long-term fund assets would be a decrease (increase) of post retirement benefit costs in the year 2011 by approximately Euro 4 million, corresponding to the increase (decrease) in expected return on assets, and the impact of an increase (decrease) by 1% in the health care cost trend rate would be an increase (decrease) of post retirement benefit costs in the year 2011 by approximately Euro 4 million (Euro 3 million).

14.1.1. Pension and supplement benefits

As referred to in Note 3.h, PT Comunica¸coes is responsible for the payment of pension ˜ supplements to retired and active employees. Prior to the transfer of unfunded pension obligations to the Portuguese State, PT Comunica¸coes was also responsible for the payment of pensions. These ˜ liabilities, which were estimated based on actuarial valuations, are as follows:

• a) Retirees and employees of Telecom Portugal (''Plan CGA'') hired prior to 14 May 1992, or who were retired on that date, were entitled to receive a pension benefit from PT Comunica¸coes. Employees hired after that date are covered by the general Portuguese ˜ Government social security system. Following the transfer of pension obligations to the Portuguese State, PT Comunica¸coes is no longer responsible for these pension benefits since ˜ 31 December 2010.
• b) Retirees and employees of Companhia Portuguesa Radio Marconi, S.A. (''Marconi'', a ´ company merged into PT Comunica¸coes in 2002) hired prior to 1 February 1998 are entitled ˜ to a pension benefit from Caixa Marconi and to a supplemental pension benefit (''Marconi

Complementary Fund''). In addition, PT Comunica¸coes contributes to the fund ''Fundo de ˜ Melhoria Marconi'' with 1.55% of salaries paid to these employees, which is responsible to pay the additional pension supplement. Following the transfer of pension obligations to the Portuguese State, PT Comunica¸coes in no longer responsible for the pension benefits since ˜ 31 December 2010, but remains responsible for supplemental pension benefits and for the contribution to the Fundo de Melhoria Marconi.

• c) Retirees and employees of TLP and TDP hired prior to 23 June 1994 are entitled to receive a pension supplement from PT Comunica¸coes, which complements the pension paid by the ˜ Portuguese social security system.
• d) On retirement, PT Comunica¸coes pays a lump sum gratuity of a fixed amount which depends ˜ on the length of service completed by the employee.

14.1.2. Health care benefits

As referred to in Note 3.i), PT Comunica¸coes sponsored the payment of post retirement health ˜ care benefits to certain suspended employees, pre-retired employees, retired employees and their eligible relatives. Health care services are rendered by PT-ACS, which was incorporated with the only purpose of managing the Company's Health Care Plans.

These plans, sponsored by PT Comunica¸coes, include all employees hired by PT Comunica¸ ˜ coes ˜ until 31 December 2000 and by Marconi until 1 February 1998. Certain employees of PT SI who were transferred from PT Comunica¸coes are also covered by this health care plan. ˜

As at 31 December 2011 and 2010, healthcare plans from PT Comunica¸coes and PT SI covered ˜ 24,401 and 24,857 beneficiaries related to employees and former employees, of which approximately

14.2. Brazilian operations—Oi

Following the acquisition of the investment in Oi, concluded on 28 March 2011 (Note 1), Portugal Telecom proportionally consolidated the net post retirement benefits obligations of Telemar and its subsidiaries, which amounted to Euro 52 million as at 31 March 2011, including a liability of Euro 63 million (Note 2.b) and an asset of Euro 11 million (Note 2.b), as detailed in the tables below. Telemar and its subsidiaries sponsor post retirement benefit plans for their employees, provided that they elect to be part of such plan, and current beneficiaries. The table below shows the existing pension plans as at 31 December 2011 and its main features:

Post retirement benefits plan	Benefits	Manager(i)	Type	Features
BrTPREV(ii)	Pension complement	FATL	Defined contributions	Contributions are set based on actuarial studies, using the capitalization approach to determine its funding. The contributions are credited to individual accounts of each participant, divided equally by the employee and the sponsor, and the basic contribution percentages range from 3 to 8 percent of the participant's salary, depending on the participant's age. Participants have the option to make additional contributions to the plan, which are not matched by the sponsor. The sponsors are responsible for funding all administrative costs and risk benefits, except for self-sponsored participants and the deferral of benefits.
Fundador/ Alternativo(ii)	Pension complement	FATL	Defined benefits	The regular contribution made by the sponsor is matched by the regular contribution of the participant, whose rates vary according to age, length of service and salary. For participants linked to the rules of the former Alternativo-BrT Plan, contributions are limited to three times the INSS benefit cap and the participant also pays an entry fee, depending on the age at which he/she joins the plan.

PBS-TELEMAR	Pension complement	FATL	Defined benefits	Plan closed to new participants since the incorporation of TelemarPrev. Approximately 96% of its former participants migrated to TelemarPrev. The contributions from active participants correspond to the sum of: (1) 0.5 to 1.5 percent of the contribution salary (according to the participant's age); (2) 1% of contribution salary that exceeds half of one Standard Unit; and (3) 11% of the contribution salary that exceeds one Standard Unit. The sponsors' contributions are equivalent to 9.5% of the payroll of active participants of the plan, of which 8% are allocated to the PBS-Telemar plan and 1.5% to PAMA and PAMA/PCE, this latter in the case of participants that migrated to the new plan. The plan is funded under the capitalization approach.

TCSPREV	Pension complement	FATL	Defined contributions and defined benefits	Contributions are set based on actuarial studies, using the capitalization approach to determine funding. Currently, contributions are made by the participants and the sponsor only for the internal groups PBS-TCS (defined benefit) and TCSPREV (defined contribution). In the TCSPREV group, the contributions are credited to the individual account of each participant, divided equally by the employee and the sponsor, and the basic contribution percentages range from 3 to 8 percent of the participant's salary, depending on the participant's age. Participants have the option to make additional contributions to the plan, which are not matched by the sponsor. In the PBS-TCS group, the sponsor's contribution corresponds to 12% of the participants' payroll, whereas the employee's contribution varies according to his/her age, length of service and salary, and an entry fee may also be paid depending on the age at which he/she joins the plan. The sponsors are responsible for funding all administrative costs and risk benefits, except for self-sponsored participants and the deferral of benefits.

TelemarPrev	Pension complement and discretionary benefits (annuities)	FATL	Defined benefits	A participant's regular contribution is comprised of two portions: (1) basic— equivalent to 2% of the salary; and (2) standard—equivalent to 3% of the positive difference between salary and the social security contribution. The additional extraordinary contributions from participants are optional and can be made in multiples of 0.5% of the salary, for a period of not less than six months. Non-recurring extraordinary contributions from participants are also optional and cannot be lower than 5% of the contribution salary cap. The plan's charter requires the parity between participants' and sponsors' contributions, up to the limit of 8% of the contribution salary, even though a sponsor is not required to match extraordinary contributions made by participants. The plan is funded under the capitalization approach.
PBS-A	Pension complement	SISTEL	Defined benefits	Contributions are contingent on the determination of an accumulated deficit.
PBS-TNCP	Pension complement and medical care	SISTEL	Defined benefits	Contributions correspond to 15.9% of the payroll of employees participating in the plan. The pension benefit is defined as the difference between 90% of average salary of the previous 36 months, adjusted for inflation, and the retirement benefit paid by the INSS.

Sponsors can make four types of contributions: (1) basic, equal to the participant's contribution; (2) additional regular, equal to the additional regular participant's contribution; (3) non-recurring, made voluntarily and with the frequency set by the sponsor; and (4) special, applicable exclusively for some employees who have joined the plan during a specific period of time.
PAMEC	Medical care	BrT	Defined benefits	The contributions for PAMEC were fully paid in July 1998, through a bullet payment. However, as this plan is now administrated by Brazil Telecom, there are no assets recognized to cover current expenses, and the actuarial obligation is fully recognized in the statement of financial position.

⁽i) Oi's post retirement benefits plans are managed by two foundations: Funda¸cao Atl ˜ antico de Seguridade Social ˆ (''FATL'') and Funda¸cao Sistel de Seguridade Social (''SISTEL''). FATL is a non-profit pension-related entity, ˜ with financial and administrative independence, engaged in the management and administration of pension benefit plans for the employees of its sponsors. SISTEL is a non-profit, private welfare and pension entity, established in 1977, which is engaged in creating private plans to grant benefits in the form of lump sums of annuities, supplementary or similar to the government retirement pensions, to the employees and their families who are linked to the sponsors of Sistel.

(ii) Included together in the following tables with the designation ''BrTPREV/FA''.

The bylaws provide for the approval of the supplementary pension plan policy, and the joint liability attributed to the defined benefit plans is ruled by the agreements entered into with the pension fund entities, with the agreement of the National Pension Plan Authority (''PREVIC''), as regards the specific plans. The sponsored defined benefit plans are closed to new entrants because they are close-end pension funds. Participants' and sponsor' contributions are defined in the funding plan.

Net actuarial losses and gains regarding plans from Portuguese operations that are related to changes in actuarial assumptions resulted from the changes in the financial and demographic actuarial assumptions detailed in Note 14.1, as follows:

• Net actuarial gains recognized in 2011 amounting to Euro 19 million correspond to the reduction of the salary increase rate for responsabilities with salaries payable to suspended and pre retired employees;
• Net actuarial losses recognized in 2010 amounting to Euro 442 million relate primarily to the reduction in the discount rate (Euro 352 million) and an adjustment in the mortality tables (Euro 100 million);
• Net actuarial gains recognized in 2009 amounting to Euro 2 million include primarily the impacts of the reduction in the discount rate (loss of Euro 99 million) and the changes in the

14. Post retirement benefits (Continued)

disability table (gain of Euro 39 million) and in the percentage of active employees with spouses as additional beneficiaries under the plan (gain of Euro 69 million).

The detail of net actuarial gains and losses resulting from differences between actual data and actuarial assumptions regarding plans from Portuguese operations is as follows:

• Net actuarial losses recognized in 2011 amounting to Euro 91 million include (1) a loss of Euro 98 million related to the difference between actual (16.6%) and expected (+6.0%) return on plan assets,and (2) a gain of Euro 7 million related to the difference between actual data and actuarial assumptions related to projected benefit obligations;
• Net actuarial losses recognized in 2010 amounting to Euro 9 million include (1) a loss of Euro 76 million related to the difference between actual (2.8%) and expected (6.0%) return on assets and (2) a gain of Euro 67 million related to the difference between actual data and actuarial assumptions related to projected benefit obligations, namely lower health care expenses and differences in the salary growth rate;
• Net actuarial gains recognized in 2009 amounting to Euro 163 million relate mainly to the difference between actual (15.0%) and expected (6.0%) return on assets (Euro 179 million).

Net actuarial losses recognized by Oi amounted to Euro 9 million in the nine months period between 31 March and 31 December 2011 and include (1) an actuarial gain of Euro 28 million related to the change in the actuarial assumptions described in Note 14.2, reflecting primarily the increase in the expected return on assets, (2) an actuarial loss of Euro 108 million resulting from differences between actual data and actuarial assumptions, and (3) an actuarial gain of Euro 71 million corresponding to the cap effect on recognition of plan assets (IFRIC 14).

(i) The increase in these captions during the year ended 31 December 2011 is primarily explained by the proportional consolidation of Oi as from 31 March 2011. The decrease in the year ended 31 December 2010 relates mainly to the transfer of the defined benefit pension plans to the Portuguese State, as mentioned above.

15. Other costs, net

Other costs in the years ended 31 December 2011, 2010 and 2009 amounted to Euro 33 mllion, Euro 141 million and Euro 46 million, respectively. In 2011, this caption includes primarily donations, fines and other penalties and the write-off of certain tangible fixed assets. The higher expenses recorded in 2010 as compared to both years 2011 and 2009 relates mainly to the following non-recurring items recognized in the third quarter of 2010: (1) non-recurring provisions and adjustments amounting to approximately Euro 50 million (Note 42) that were recognized in order to adjust certain receivables and inventories to their recoverable amounts and reflect estimated losses with certain legal actions; and (2) expenses incurred in the third quarter of 2010 for services rendered in relation to the acquisition of the investment in Oi Group (Euro 25 million).

16. Net interest expenses

The composition of this caption in the years ended 31 December 2011, 2010 and 2009 is as follows:

	2011	2010	2009
		Euro

Related to loans obtained and financial
instruments	638,279,821	282,729,191	257,997,581

	297,114,673	185,044,935	227,491,155

In 2011, the increase in net interest expenses is primarily explained by the impact of the proportional consolidation of Oi, Contax and its controlling shareholders as from 1 April 2011, amounting to Euro 175 million (Note 2.b). Excluding for this effect, net interest expenses would have amounted to Euro 122 million in 2011, a reduction of Euro 63 million as compared to Euro 185 million in 2010, reflecting (1) the interest income recognized in the first quarter of 2011 resulting from cash deposits in Brazilian Reais that were used to pay the investments in Oi and Contax on 31 March 2011, and (2) the interest income related to the present value of the receivable from Telefonica regarding the ´ disposal of Vivo. These effects more than offset the impact of the increase in the average net debt from Portuguese operations.

The decrease in net interest expenses in 2010, as compared to 2009, is primarily explained by (1) a reduction in average net debt, following the first installment received from Telefonica in September ´ 2010 related to the disposal of the 50% stake in Brasilcel, and (2) the financial effect on the outstanding receivables from Telefonica in connection with this transaction, which explains the increase ´ in other interest income. These effects were partially offset by an increase in average cost of debt.

17. Net foreign currency exchange losses

Net foreign currency exchange losses in the years ended 31 December 2011, 2010 and 2009 amounted to Euro 18 million, Euro 7 million in 2010 and 0.2 million, respectively. The increase occurred in 2011 refects primarily the impact of the proportional consolidation of Oi as from 1 April 2011 (Euro 16 million), the losses of which mainly relate to the impact of the depreciation of the Brazilian Real against the US Dollar on Oi's gross debt denominated in US Dollars that is not hedged through currency swaps or cash applications (Note 45). In addition, Oi's contribution to this caption includes gains on currency swaps which offset net foreign exchange losses related to the US Dollar debt that is hedged through those currency swaps.

18. Net gains on financial assets and other investments

The composition of this caption in the years ended 31 December 2011, 2010 and 2009 is as follows:

	107,402,475	33,300,530	35,715,551

⁽i) The increase in this caption in 2011 relates mainly to the impact of the proportional consolidation of Oi and Contax as from 1 April 2011, amounting to Euro 24 million, and to a higher level of bank commissions at Portuguese operations.

⁽ii) The increase in this caption in 2011 reflects primarily (1) the financial taxes paid in Brazil during the first quarter of 2011 in connection with the transfer of funds for Portugal Telecom's investment in Oi (Euro 14 million), and (2) the impact of the proportional consolidation of Oi and Contax, amounting to Euro 29 million. These effects were partially offset by a gain of Euro 2 million (Note 38.2) recognized in 2011 corresponding to the difference between the nocional value and the acquisition price of own bonds acquired during the fourth quarter of 2011.

20. Income taxes

As from 1 January 2010, following a change in Portuguese tax legislation occurred in the second quarter of 2010, Portugal Telecom and its subsidiaries located in Portugal are subject to Corporate Income Tax at a maximum aggregate tax rate of approximately 29.0%, corresponding to a base rate of 25%, which is increased (1) up to a maximum of 1.5% of taxable income through a municipal tax and (2) by a 2.5% state surcharge applicable to taxable income in excess of Euro 2.0 million. Prior to this change, the 2.5% state surcharge did not exist and, consequently, the maximum aggregate income tax rate was approximately 26.5%.

For the years 2012 and 2013, following a change in Portuguese tax legislation occurred in December 2011, the Company will be subject to Corporate Income Tax at a base rate of 25%, increased (1) up to a maximum of 1.5% of taxable income through a municipal tax, and (2) by a state surcharge levied at the rate of 3.0% on taxable income between Euro 1.5 million and Euro 10.0 million and at the rate of 5.0% on taxable income in excess of Euro 10.0 million, resulting in a maximum aggregate tax rate of approximately 31.5%.

Portugal Telecom adopted the tax consolidation regime for groups of companies, which apply to all companies located in Portugal in which it holds at least 90% of the capital stock and that comply with Article 69 of the Portuguese Corporate Income Tax Law.

Companies located in Brazil, namely Oi and Contax that were proportionally consolidated as from 1 April 2011, are subject to income tax at a nominal rate of 34%.

In accordance with Portuguese tax legislation, income tax returns are subject to review and adjustment by the tax authorities during a period of four calendar years (five years for social security, and ten years for the contributions made with respect to the years before 2001), except when there are tax losses, tax benefits were granted, or when tax inspections, claims or appeals are in progress, in which case the time periods are extended or suspended. In Brazil, income tax returns are subject to review and adjustment by the tax authorities during a period of five calendar years. The Board of Directors of Portugal Telecom, based on information from its tax advisors, believes that any adjustments which may result from such reviews, as well as other tax contingencies, will not have a material impact on the consolidated financial statements as at 31 December 2011, considering the provisions recognised by the Company (Note 42).

(i) Changes in the consolidation perimeter include (1) the impact of the proportional consolidation of deferred tax assets and liabilities from Oi and Contax, amounting to Euro 658 million and Euro 873 million (Note 2.b), respectively, totaling a net amount of Euro 215 million, and (2) the net effect of Euro 12 million related to the deferred tax assets from Dedic/GPTI, which were fully consolidated until 30 June 2011, amounting to Euro 22 million (Note 2.b), and proportionally consolidated as from that date following the integration in Contax.

(ii) This caption corresponds mainly to the impact resulting from the increase in the statutory tax rate applicable in Portugal for the years ended 31 December 2012 and 2013, as mentioned above.

(iii) Foreign currency translation adjustments relate mainly to the impact of the depreciation of the Brazilian Real against the Euro since 31 March 2011.

(iv) This caption includes tax losses carryforward from Portugal Telecom (Euro 116 milllion), Oi (Euro 203 million) and Contax (Euro 13 million). Portugal Telecom's tax losses carryforward, which were generated in 2011, have a maturity of five years and can only be used up to a limit of 75% of taxable profits for each period. Tax losses carryforward of Oi and Contax, which were generated mainly in previous years, have no maturity but can only be used up to a limit of 30% of taxable profits for each period.

(i) Changes in the consolidation perimeter correspond to 50% of Vivo's deferred tax assets and liabilities following the completion of the disposal of the 50% stake in Brasilcel in September 2010.

(ii) Changes in deferred taxes recorded through net income were split between continuing and discontinued operations amounting to a gain of Euro 24,867,108 and an expense of Euro 28,589,220, respectively.

(iii) The impacts on net income resulting from changes in tax rate correspond primarily to the revision of the tax rate applicable for certain companies located in Portugal, namely related to the above mentioned increase in the statutory tax rate in Portugal and to the decrease in the tax rate applicable for certain companies that are expected to present tax losses in the following years.

(iv) Foreign currency translation adjustments relate primarily to the impact of the appreciation of the Brazilian Real against the Euro up to the completion of the disposal of the 50% stake in Brasilcel.

(v) The increase in this caption corresponds to the tax effect associated with the equity component of the exchangeable bond obtained by Portugal Telecom in 2007 (Note 38), which was recognized as a result of changes occurred in the Portuguese tax legislation in 2010.

(vi) Other deferred tax liabilities correspond primarily to the tax effect on unpaid dividends from associated companies.

As at 31 December 2011 and 2010, total deferred tax assets include respectively Euro 628 million and Euro 19 million from foreign countries, and total deferred tax liabilities include respectively Euro 852 million and Euro 64 million from foreign countries. As at 31 December 2011, deferred tax assets and liabilities from foreign countries were primarily related to Oi and Contax.

	108,196,813	77,525,848	185,890,157

⁽i) This caption corresponds to the impact of the difference between the statutory tax rate applicable in Portugal and other tax rates applicable to Group companies, namely foreign operations. The increase in this caption in 2011 reflects primarily (1) lower taxable losses from PT Comunica¸coes, ˜ which uses a 25% tax rate that is lower than the statutory 29%, and (2) Oi's taxable losses that were proportionally consolidated as from 1 April 2011, leading to an increase in this caption as the Brazilian tax rate of 34% is higher that the Portuguese statutory tax rate of 29%. The change in this caption from 2009 to 2010 reflects basically the effect of higher taxable losses from PT Comunica¸coes in 2010. ˜

(ii) The reduction in this caption in 2011 is primarily explained by (1) lower non-deductible interest expenses for tax purposes, and (2) non-recurring losses recognised on investments in associated companies in the third quarter of 2010, as mentioned in Note 34, which were non-deductible for tax purposes. The change in this caption from 2009 to 2010 is primarily explained by (1) the effect of the non-taxable capital gain recognized in 2009 in relation to the disposal of the equity investement in Medi T ´ el ´ ecom (Note 34), and (2) the above mentioned non-deductible expenses ´ recorded in 2010.

• (iii) In 2011, based on favourable legal court decisions, Portugal Telecom recognized a receivable from tax authorities of Euro 13 million related to the municipal tax of 1,5% paid in excess in previous years.
• (iv) This caption corresponds primarily to the changes in the Portuguese statutory tax rate described above that occurred in 2011 and 2010. In 2010, the maximum aggregate tax rate applicable in Portugal increased from 26.5% to 29% for companies with expected taxable profits higher than Euro 2 million and therefore deferred taxes of certain domestic companies were adjusted for, resulting in a gain of Euro 0.4 million. As from January 2012, the maximium aggregate statutory tax rate applicable in Portugal increased to 31.5% and, consequently, deferred taxes of Portuguese companies were adjusted for, resulting in a gain of Euro 2 million.
• (v) The gain recorded in 2010 resulted from the decrease in deferred tax liabilities related to unpaid dividends from foreign equity investments, following a reduction in the estimated applicable tax rate, as Portugal Telecom decided to transfer the headquarters of the holding company of those investments to Madeira, where the tax rate applicable to dividends received from foreign operations is lower than in continental Portugal.
• (vi) The increase in income taxes in the year ended 31 December 2011, as compared to 2010, is primarily explained by (1) the above mentioned Euro 59 million tax gain recorded in 2010, and (2) the impact of the proportional consolidation of Oi, Contax and its controlling shareholders as from 1 April 2011, amounting to Euro 7 million (Note 2.b). The reduction in the year ended 31 December 2010, as compared to 2009, reflects mainly (1) the Euro 59 million gain recorded in 2010 and (2) the impact of lower taxable earnings mainly due to higher work force reduction and other costs in 2010.

21. Discontinued operations

In 2010, Vivo was classified as a discontinued operation following the agreement reached between Portugal Telecom and Telefonica on 28 July 2010 for the disposal of its 50% stake in Brasilcel, which ´ was completed in September 2010. Consequently, financial information relating to Portugal Telecom's former mobile business in Brazil was restated to be presented as a discontinued operation. The sale was agreed for a total consideration of Euro 7,500 million, of which Portugal Telecom received Euro 4,500 million on 27 September 2010, Euro 1,000 million on 30 December 2010 and Euro 2,000 million on 31 October 2011, in accordance with the terms of the agreement with Telefonica. ´

Portugal Telecom recognized a net gain of Euro 5,423 million (Note 1) in connection with the sale of Vivo, which includes: (1) Euro 4,390 million corresponding to the difference between the total consideration agreed with Telefonica (Euro 7,500 million) and the carrying value of the investment in ´ Brasilcel on the date of the disposal (Euro 3,110 million); (2) Euro 1,134 million corresponding to the cumulative foreign currency translation adjustments transferred to net income; (3) Euro 47 million related to the difference between the outstanding amounts due by Telefonica as at 27 September 2010 ´ (Euro 3,000 million) and the respective present value (Euro 2,953 million); and (4) Euro 54 million related to legal and financial advisory fees and other costs related to the sale. In accordance with Portuguese tax legislation, the capital gain obtained with the disposal of Vivo is not taxable.

21. Discontinued operations (Continued)

Net income from discontinued operations in 2010 includes (1) the gain of Euro 5,423 million recognized on the sale, as explained above, (2) Portugal Telecom's 50% stake of Vivo's net income before non-controlling interests up to the conclusion of the sale of this business (Euro 110 million), and (3) positive foreign currency translation adjustments (''CTA's'') transferred to net income prior to the sale (Euro 32 million), following share capital reductions undertaken by Brasilcel in 2010.

The increase in total taxes receivable and payable is basically explained by the impact of the proportional consolidation of Oi and Contax as from 31 March 2011, the receivables and payables of which were included under the captions ''Taxes in foreign operations''.

As at 31 December 2011 and 2010, the composition of the captions ''Taxes in foreign countries'' is as follows:

	2011		2010

Current taxes:
Indirect taxes(i)	165,314,829	85,147,046	—	121,175

	56,406,992	314,374,825	267,622	3,805,301

(i) Indirect taxes relate mainly to State Value Added Tax (ICMS). Non-current recoverable State VAT (ICMS) arises mostly from credits claimed on purchases of property, plant and equipment, which can be offset against ICMS payable within 48 months, pursuant to Brazilian tax legislation.

• (ii) These captions relate to taxes payable by Oi and Contax in connection with tax refinancing programs in force in Brazil, under which companies enrolled a substantial portion of their debt to the National Treasury and the National Social Security Institute (''INSS'') past due up to 30 November 2008. Taxes due under these programs include mainly Pis (Social Integration Programme) and Cofins (Contribution to the Financing of Social Security), income taxes, IOF (tax on financial transactions) and CPMF (tax on banking transactions). In accordance with the terms of these programs, companies are required to pay monthly instalments, mainly up to 2024, and may be excluded from the plan if they fail to make such payments on due date for a specific number of times.
• (iii) Other current taxes payable as at 31 December 2011 relate primarily to (1) the federal taxes Pis and Cofins, (2) Fust (fund to improve the general access to telecommunications services) and Funttel (National Telecommunications Fund) fees and (3) social charges due to the Brazilian social security system.
• (iv) Other non-current taxes payable as at 31 December 2011 include primarily taxes for which payment is suspended, in accordance with Brazilian tax legislation.

Other	25,454,341	14,779,277
	73,584,328	39,617,800

The increase in this caption is primarily explained by the impact of the proportional consolidation of Oi.

31. Judicial deposits

Oi and Contax have several legal proceedings, including civil, labor and tax contingencies (Note 42.2), for which, in accordance with Brazilian law, companies are required, in certain situations, to make judicial deposits or to present financial guarantees with the applicable judicial entities. These judicial deposits are made in connection with legal actions for which risk of loss was deemed either probable, possible or remote, based on the decision of judicial authorities, and generally bear interest or are adjusted for inflation.

Current and non-current judicial deposits of Oi and Contax that were proportionally consolidated for the first time as at 31 March 2011 amounted to Euro 208 million (Note 2.b) and Euro 776 million (Note 2.b), respectively, totaling Euro 984 million. As at 31 December 2011, judicial deposits totaled Euro 1,084 million, as follows:

2011

	132,710,054	274,640,756

(i) The increase in this caption relates mainly to the proportional consolidation of Oi.

As explained in Note 3.l.viii, in previous years Portugal Telecom entered into cross-border lease transactions (QTE transactions). Pursuant to these transactions, Portugal Telecom recognized in the Consolidated Statement of Financial Position accounts receivable and accounts payable by the same amount relating to the sale of the equipments and the financial lease, respectively. The majority of these amounts are receivable and payable to the same entity and Portugal Telecom has issued letters of credit under these transactions (Note 46). During the year ended 31 December 2011, the Company agreed with the other parties to these arrangements to early terminate several of these QTE transactions, which explains the reduction in the related non current receivables and payables. As a result of the termination of these contracts, the Company did not incur in material costs (Note 43).

33. Non-current assets and liabilities held for sale

In December 2010, Portugal Telecom reached an agreement with a third party for the disposal of its 28.78% stake in UOL for a total amount of R\$ 356 million (Euro 160.4 million at the exchange rate prevailing at year-end), following which the investment in UOL as at 31 December 2010 was adjusted to its recoverable amount, corresponding to the amount to be obtained with this sale, and was classified as a non-current asset held for sale. Upon the closing of this transaction on 27 January 2011, Portugal Telecom received a total amount of Euro 155.5 million (Note 47.e) and recognized a gain of Euro 37.6 million (Note 34) corresponding to the cumulative amount of foreign currency translation adjustments relating to the investment in UOL that was reclassified to profit and loss.

⁽i) The increase in the carrying value of this investment is explained by Portugal Telecom's share in the earnings of Unitel (Euro 156 million) and also by the impact of the appreciation of the US Dollar against the Euro in 2011 (Euro 18 million).

(ii) The change in the carrying value of this investment reflects primarily Portugal Telecom's share in the earnings of CTM (Euro 23 million) partially offset by the dividends attributed by this associated company (Euro 20 million—Note 47.g).

(iii) The reduction in this caption relates primarily to a loss of Euro 7 million recognised over the Company's investment in Paginas Amarelas, reflecting the decline in the directories ´ business.

⁽i) This caption corresponds to accumulated losses resulting from the equity method of accounting in excess of the value of investments in associated companies, which for that reason are recorded as a reduction to the value of loans granted to those associated companies. These adjustments as at 31 December 2011 and 2010 correspond to the investment in Sportinveste Multimedia.

36.1. Changes in the consolidation perimeter

The impact of changes in the consolidation perimeter in the year ended 31 December 2011, amounting to Euro 3,558 million, includes primarily:

• Intangible assets of Oi and Contax that were proportionally consolidated in Portugal Telecom's Statement of Financial Position for the first time as at 31 March 2011, totalling Euro 3,558 million (Note 2.b), including the carrying value of those assets (Euro 2,031 million) and the fair value adjustments recorded under the purchase price allocation (Euro 1,527 million).
• The proportional consolidation of Allus's intangible assets, amounting to Euro 13 million as at 30 April 2011 (Note 2.b);

• The impact of the increase in the proportional consolidation stake of Contax from 42.0% to 44.4%

Changes in the consolidation perimeter in 2010, amounting to Euro 3,115 million, relate primarily to the sale of the 50% stake in Brasilcel, which had intangible assets amounting to Euro 3,115 million as at the date this investment was sold (Note 21), and the disposal of a 35.6% stake in PT Prime Tradecom.

⁽i) In 2011, this caption includes (1) a total goodwill of Euro 904 million generated in the acquisition of the investments in Oi, Contax and its controlling shareholders, including Euro 872 million related to Oi and Euro 31 million related to Contax (Note 2.b), (2) the goodwill of Euro 29 million (Note 2.b) recorded by Contax as a result of the acquisition of Allus, and (3) the total goodwill amounting to Euro 28 million (Note 1) recognized as a result of the operations completed on 1 July 2011 regarding the Contax transaction. In 2010, this caption corresponds to the goodwill generated in the acquisition of GPTI (Note 2.b).

⁽ii) In relation to a mobile spectrum auction conducted by the Portuguese telecommunications regulator ICP-Anacom, TMN submitted the best winning bids in each block that it has bided and obtained spectrum in three frequency bands for a total amount of Euro 113 million, thus reinforcing its commitment to the LTE technology, strengthening TMN's mobile data capabilities and its network quality to continue to lead data services in Portugal and also to lead the roll-out of 4G services. As a result, TMN recognized an intangible asset amounting to Euro 106 million (Notes 7.b and 39), which corresponds to the present value of the instalments payable to Anacom totalling Euro 113 million.

• (iv) Cabo Verde Telecom recorded an intangible asset in 2011, amounting to Euro 6 million, related to the commitments assumed under the 3G license.

36.3. Foreign currency translation adjustments

Foreign currency translation adjustments in 2011 relate mainly to the impact of the depreciation of the Brazilian Real against the Euro since 31 March 2011, the date of the first proportional consolidation of Oi and Contax. Foreign currency translation adjustments in 2010 relate mainly to the impact of the appreciation of the Brazilian Real against the Euro up to 27 September 2010, when Portugal Telecom sold its former investment in Brasilcel.

36.4. Other information regarding intangible assets

As at 31 December 2011, the net carrying value of the caption ''Industrial property and other rights'' includes mainly the following items:

• Euro 2,800 million related to regulatory licenses held by Oi Group, including both mobile licenses and fixed line concessions, which were adjusted to fair value as at 31 March 2011, following the purchase price allocation performed by Portugal Telecom under the acquisition of the investment in Oi (Note 2.b);
• Euro 378 million related to 3G and 4G licenses obtained by TMN in 2000 and 2011, respectively, corresponding to a gross amount of Euro 500 million net of accumulated depreciation of Euro 122 million. The gross amount includes primarily:
  • (i) Euro 133 million related to the acquisition of the UMTS license in 2000;
  • (ii) Euro 242 million capitalized in 2007, following the commitment assumed in 2000 by TMN and the other mobile operators of making contributions to the information society during the period through the maturity of the license, and Euro 11.5 million capitalized in 2009 related to additional commitments under the terms of the UMTS license. Since in the year 2000 it was not possible to reliably estimate how the commitment would be fulfilled, Portugal Telecom did not recognize this commitment as a cost of the license and as a liability. During the second half of 2007, TMN reached an agreement with the Government establishing the amount and timing of the initiatives to be undertaken (the ''E Initiatives'', which is a programme led by the Government to offer laptops and discounts in internet services to school teachers and students), and in 2007 therefore Portugal Telecom recognized as a license cost the amount of these contributions at net present value; and
  • (iii) Euro 106 million (Notes 7 and 39) related to the 4G license acquired by TMN in 2011.
• Euro 282 million corresponding to the fair value, net of accumulated depreciation, of the customer bases of Oi and Contax, which were recognized at fair value as at 31 March 2011

• Euro 189 million related to software licenses;
• Euro 34 million related to the cost incurred with loyalty contracts with post-paid customers of mobile businesses, which are being amortised over the period of the related rental contracts, corresponding to a two year period;
• Euro 25 million related to contracts signed by PT Comunica¸coes in 2007 and 2009 for the ˜ acquisition of satellite capacity until 2015, which were recorded as capital leases; and
• Euro 24 million (Notes 7 and 39) related to the commitments assumed by PT Comunica¸coes ˜ under the TDT license.

• (iii) This caption corresponds to the goodwill recorded by Dedic regarding the acquisition of the investment in GPTI completed on 7 February 2010 (Note 2.b), which as at 31 December 2011 is proportionally consolidated in Contax, as mentioned above.
• (iv) The change in this caption relates primarily to the impact of the depreciation of the Namibian Dollar against the Euro during the year ended 31 December 2011.

For the goodwill related to the wireline cash generated unit in Portugal, which resulted from the acquisition of several companies, some of which were subsequently merged, the Company monitors goodwill at this level, which is a lower level than the operating segment to which it belongs.

For the goodwill related to other cash generated unit, Portugal Telecom also concluded that the Company's share in net assets of those investments represents the lowest level of assets that generates cash inflows, since they are totally independent from the other investments.

For purposes of impairment analysis, goodwill was allocated to cash generating units. The recoverable amount was computed based on a value in use through a discounted cash flow methodology, using a detailed forecast of cash flows for a 4 year period (except for Brasil where it was used a forecast of cash flows for a 15 year period), which was prepared internally. The discount rates applied to the cash flow projections, which were determined taking into consideration the risks associated to each business, and the growth rates used to extrapolate cash flow projections beyond the period covered by the forecasts were as follows:

Assumptions	Telecommunications in Brazil	Wireline telecommunications in Portugal	Other businesses
Growth rates	4.5% - 5.0%	0.0% - 2.0%	0.0% to 2.5% - 0.5% to 3.0%
Discount rates	9.0% - 9.5%	8.5% - 10.0%	5.9% to 11.4% - 5.9% to 13.4%

The recoverable amount of each cash generating unit was determined for the minimum and maximum values included in the table above and the Company's management has concluded that as at 31 December 2011 the carrying value of financial investments, including goodwill, did not exceed its recoverable amount.

37.4. Revaluations

During 2008, Portugal Telecom changed the accounting policy regarding the measurement of real estate properties and the ducts infra-structure from the cost model to the revaluation model (Note 3). The revaluations of the real estate properties and ducts infra-structure were effective as at 30 June 2008 and 30 September 2008, and resulted in a revaluation of the assets by Euro 208,268,320 and 866,764,702, respectively, totalling an amount of Euro 1,075,033,022 that was recognized in the Consolidated Statement of Comprehensive Income.

The determination of the fair value of real estate properties was made by an independent appraiser based primarily on: (i) observable prices in an active market of recent market transactions; (ii) profitability method for commercial and administrative real estate; and (iii) the cost of acquiring or producing a similar real estate with the same purpose for technical buildings. Under the first methodology, the main assumptions used in 2008 were the discount rate (average of 8%) and the monthly rent per square meter (average of 6 Euros).

The determination of the fair value of the ducts infra-structure was made internally based on the replacement cost approach. This valuation process was based primarily on: (i) current and observable prices of materials and construction work related to the installation of the ducts underground; (ii) the nature of the soil and road surface where ducts are installed, which has an impact on the construction cost; (iii) internal costs directly attributable to the construction of the ducts infra-structure network; (iv) a depreciation factor, in order to ensure that the replacement cost is consistent with the remaining useful life of the assets revalued; and (v) a technological factor, which reflects the technological changes occurred, namely related to the kinds of ducts which no longer exist and were replaced by other ones. Generally, the prices of materials and construction work together with other qualitative assumptions referred to above resulted in a valuation of the ducts infra-structure in 2008 which reflects an average cost per meter of duct between Euro 58 and Euro 119, depending on the area where the infra-structure is located.

In accordance with the Group's accounting policy to revalue these assets at least every three years, Portugal Telecom performed another revaluation of the real estate assets and ducts infrastructure in the year ended 31 December 2011, through the same methodology described above. These revaluations were effective as at 31 December 2011 and resulted in a net reduction of tangible assets amounting to Euro 131,418,994, of which Euro 126,167,561 was recognized directly in the Consolidated Statement of Comprehensive Income (Note 44.5) under the caption ''Revaluation reserve'' and Euro 5,251,433 was recognized in the Consolidated Income Statement under the caption ''Depreciation and amortization''. The split of these impacts between real estate and ducts infrastructure is as follows:

• A reduction in the carrying value of the ducts infrastructure amounting to Euro 189,372,570, recognized in other comprehensive income in order to reduce the existing revaluation reserves regarding these assets, which is primarily explained by a decrease in the construction cost and also technological improvements, leading to a reduction in the average cost per meter of duct to between Euro 42 and Euro 70, depending on the area where the infra-structure is located; and

37. Tangible assets (Continued)

• A net increase in the carrying value of real estate assets amounting to Euro 57,953,576, including a gain of Euro 63,205,008 recorded in other comprehensive income and a loss of Euro 5,251,432 recognized in the Consolidated Income Statement. The increase in the carrying value of real estate assets recognized as a result of this revaluation reflects mainly the depreciation and amortization expenses recorded over the last three years, as the average monthly rent per square meter for the real estate assets that were revalued in both 2008 and 2011 remained broadly stable at 6 Euros, altought the overall average monthly rent per square meter increased to 7 Euros, as a result of real estate assets acquired between those years.

The amortization of the surplus resulting from the revaluation of real estate properties and ducts infra-structure amounted to approximately Euro 12 million and Euro 45 million in 2010, respectively, and to Euro 11 million and Euro 45 million in 2011, respectively. If these assets had been carried under the cost model, the carrying amounts of the real estate properties and the ducts infra-structure would have been reduced by approximately Euro 145 million and Euro 398 million, respectively.

37.5. Other situations regarding tangible assets

The following situations regarding tangible assets should be mentioned:

• Basic equipment includes primarily network installations and equipment, including the ducts infra-structure, switching equipment, telephones and switchboards and submarine cables;
• Euro 1,995 million of tangible assets of PT Comunica¸coes relate to the Concession, under the ˜ terms of the Modification Agreement of the Concession;
• Euro 19 million of tangible assets of PT Comunica¸coes are located outside Portugal, including ˜ participations in submarine cable consortiums;
• PT Comunica¸coes had tangible assets totalling Euro 9 million which are installed in properties ˜ of third parties or on public property, and assets amounting to Euro 8 million which are not yet registered under PT Comunica¸coes's name; and ˜
• In previous years, several Group companies entered into QTE lease contracts (Notes 32 and 43), which comprised the sale of certain telecommunications equipment to foreign entities. Simultaneously, those entities entered into leasing contracts with special purpose entities, which made conditional sale agreements to sell the related equipment to those Group companies, at an amount equivalent to the initial sales price. Group companies maintained the legal ownership of those equipments, continuing to be able to sell or substitute any equipment. These transactions correspond to a sale and lease-back and, accordingly, the sale of the equipment was not recorded and the equipment continued to be included in the Company's Consolidated Statement of Financial Position.

38. Debt (Continued)

As mentioned above, the debt of Oi, Contax and its controlling shareholders that was proportionally consolidated in Portugal Telecom's Statement of Financial Position for the first time as at 31 March 2011 amounted to Euro 3,748 million. As of that date, the average maturity of this debt was approximately 4 years and approximately 90% of the debt was denominated in Brazilian Reais, directly or indirectly through cross currency derivatives. Regarding the cost of debt, as at 31 March 2011 approximately 20% was set at fixed rates and the remaining 80% beared interest at variable rates, primarily the Brazilian Interbank Deposit Rate (''CDI'') and the Brazilian Long-Term Interest Rate (''TJLP''). The features of the main financings obtained by Oi, Contax and its controlling shareholders are described in detail in the notes below.

38.1. Exchangeable bonds

On 28 August 2007, PT Finance issued exchangeable bonds totalling Euro 750,000,000, convertible into fully paid ordinary shares of Portugal Telecom, as follows:

• Exchange price of Euro 13.9859 per ordinary share of Portugal Telecom, which was adjusted to Euro 11.60 on 30 October 2007, following the spin-off of PT Multimedia, to Euro 11.06 on 28 December 2010 and to Euro 9.4 on 31 May 2011, following the dividends paid in December 2010 and June 2011, respectively, according to the terms and conditions of these bonds;

• Maturity: 28 August 2014 unless previously redeemed, acquired, cancelled or converted; and
• Fixed interest rate: 4.125% per annum, paid semi-annually.

The exchangeable bonds represent a compound instrument and accordingly the market value of the equity component as of the date the bonds were issued amounted to Euro 57,145,442 and was recorded in shareholders' equity under the caption ''Other reserves and accumulated earnings'', while the financial liability component is recorded by the amortized cost.

As at 31 December 2011, the fair value of the exchangeable bonds, determined based on market information, amounted to Euro 621 million.

These preferred shares were fully subscribed by BNDES Participa¸coes, S.A., one of the shareholders of Telemar Participa¸ ˜ coes, and its main features ˜ consist of: (1) priority in the distribution of a fixed dividend equivalent to 5% per year of the issuance price per share, adjusted by inflation; (2) annual repayments as from April 2011 at the issuance price, adjusted by inflation; (3) the holder of the preferred shares has the option to demand its repayment through shares of Telemar Norte Leste held by Telemar Participa¸coes; ˜ (4) convertible into ordinary shares of Telemar Participa¸coes if the repayment of the preferred ˜ shares is not made in accordance with its terms or the fixed dividend is not paid; and (5) do not have voting rights. Considering there features, preferred shares issued by Telemar Participa¸coes ˜ are classified as debt and amounted to R\$1,276 million as at 31 December 2011, equivalent to Euro 135 million proportionally consolidated in Portugal Telecom's Statement of Financial Position (R\$1,457 million as at 31 March 2011, corresponding to Euro 162 million proportionally consolidated).

38.9. Medium and long-term debt

As at 31 December 2011, medium and long-term debt matures as follows:

	Euro
2013	1,522,922,669
2014	2,042,658,603
2015	383,175,917
2016	1,170,176,988
2017 and following years	3,870,466,154
	8,989,400,331

38.10. Covenants

As at 31 December 2011, the Company had several covenants related to its indebtedness as follows:

• Change in control

The exchangeable bonds, the revolving credit facilities amounting to Euro 1,640 million, the loans obtained from EIB totalling Euro 594 million as at 31 December 2011, the Euro 50 million term loan and the export credit facility totalling Euro 180 million establish penalties in the case of any change of control of Portugal Telecom. According to the terms and conditions of these debt instruments, a change of control would occur if any person or group of persons acting in concert acquires or controls more than 50 per cent of the voting rights, whether obtained by ownership of share capital, the holding of voting rights or pursuant to the terms of a shareholders' agreement. In certain cases, gaining the power to appoint or remove all, or the majority, of the directors or other equivalent officers of the company or to give directions with respect to the operating and financial policies of the company with which the

38. Debt (Continued)

directors or equivalent officers of the company are obliged to comply are also considered a change of control.

The Euro 1,000 million and Euro 750 million Eurobonds issued in 2009 and the Euro 600 million Eurobond issued in 2011 establish penalties in the case of any change of control of Portugal Telecom, as described above, if simultaneously a rating downgrade to sub-investment grade occurs (in case the securities are investment grade securities) or a rating downgrade occurs (in case the securities are sub-investment grade securities) during the Change of Control Period, as defined under the terms and conditions of these notes.

• Credit rating

Certain loan agreements with the EIB, totalling Euro 129 million as at 31 December 2011, stated that Portugal Telecom may be asked to present a guarantee acceptable by the EIB if, at any time, the long-term credit rating assigned by the rating agencies to Portugal Telecom is reduced from the rating assigned by the time the clause was included (BBB- by S&P, Baa2 by Moody's and BBB by Fitch). As at 31 December 2011, the repayment schedule of the Euro 129 million loans is as follows: Euro 46 million in 2012, Euro 46 million in 2013 and Euro 36 million in 2014.

On 3 June 2011, S&P announced its review of the credit rating attributed to Portugal Telecom, downgrading the long-term rating from BBB to BBB-, with negative outlook, and the short-term rating from A-2 to A-3. On 7 June 2011, Moody's announced its review of the credit rating attributed to Portugal Telecom, downgrading the long-term rating from Baa2 to Baa3 and maintaining it under review for possible downgrade. On 29 July 2011, Moody's confirmed the Baa3 issuer rating of Portugal Telecom, with negative outlook. Considering the credit rating covenant described above, Portugal Telecom and the EIB have agreed to increase the spread of those loans, with no other consequence as a result of the revision of Portugal Telecom's credit rating.

On 23 December 2011, Moody's announced the downgrade of Portugal Telecom's long-term rating from Baa3 to Ba1. On 16 February 2012, S&P announced its review of the credit rating attributed to Portugal Telecom, downgrading the long-term rating from BBB- to BB+, and the short-term rating from A-3 to B. Following these developments, Portugal Telecom has agreed in 2012 with the EIB to open a cash deposit amounting to a portion of the amount due under the loan agreements that include the credit rating covenant, pledged in favour of the EIB. The amount deposited in this account will be reduced as loans are repaid. Portugal Telecom and the EIB have also agreed that further upgrades or downgrades of the credit rating assigned to the Company will lead to, respectively, decreases or increases in the amount deposited, with no other consequence.

The spread paid by Portugal Telecom under the Euro 1,200 million revolving credit facility depends on whether the credit ratiting is or is not higher than BBB- (as assigned by S&P) and Baa3 (as assigned by Moody's). The margin paid by Portugal Telecom under the Euro 200 million underwritten portion of a commercial paper program also depends on the credit rating assigned by S&P and Moody's.

38. Debt (Continued)

• Control/disposal of subsidiaries

Certain credit facilities in the total amount of Euro 1,445 million state that Portugal Telecom must, directly or indirectly, maintain majority ownership and control of each material subsidiary. Material subsidiaries are those companies whose total assets are equal or exceed 10% of total consolidated assets or whose total revenues are also equal or exceed 10% of total consolidated revenues.

• Disposals of assets

Credit facilities totalling Euro 150 million and the EIB loans totalling Euro 594 million as at 31 December 2011 include certain restrictions regarding the disposal of assets by Portugal Telecom.

• Financial ratios

Certain credit facilities and loans totalling Euro 1,745 million require that the ratio Consolidated Net Debt/EBITDA should not exceed certain values, which vary depending on the loan agreements. In addition, the pricing conditions applicable to certain facilities in the total amount of Euro 215 million may be changed depending on the ratio Consolidated Net Debt/EBITDA.

• Negative Pledge

The Euro Medium Term Notes, the exchangeable bonds, the revolving credit facilities, the term loan, the export credit facility and the commercial paper programmes are subject to negative pledge clauses, which restrict the pledge of security interests in the assets of companies included in the consolidation.

The penalties applicable in the event of default in any of these covenants are generally the early payment of the loans obtained or the termination of available credit facilities. As at 31 December 2011, the Company had fully complied with the covenants mentioned above.

The increase in current and non-current accounts payable is primarily explained by the impact of the proportional consolidation of Oi and Contax, amounting to Euro 303 million (Note 2.b) and Euro 202 million as at 31 March 2011, respectively.

Licenses and concessions payable as at 31 December 2011 totalled Euro 302 million, including (1) Euro 106 million payable by TMN to Anacom in relation to the 4G license acquired in December 2011 (Note 36), corresponding to the present value of the total instalments due amounting to Euro 113 million, and (2) Euro 196 million payable by the Oi Group to Anatel for the radiofrequency concessions and licenses to provide the mobile services (''SMP'') and the fixed line service concessions, which were obtained at public auctions.

(i) This caption relates to deferred revenues in connection with loyalty programmes of mobile operations, which are recognized as revenue when award credits are redeemed.

The increase in this caption is primarily explained by the impact of the proportional consolidation of Oi and Contax, amounting to Euro 79 million as at 31 March 2011, partially offset by a reduction in deferred income regarding penalties imposed to customers related to violations of contracts, which as from 1 January 2011, based on its aging, are classified on a net basis together with the related receivables.

42.3. Foreign currency translation adjustments

Foreign currency translation adjustments in 2011 relate mainly to the impact of the depreciation of the Brazilian Real against the Euro since 31 March 2011, the date of the first proportional consolidation of Oi and Contax. Foreign currency translation adjustments in 2010 relate mainly to the impact of the appreciation of the Brazilian Real against the Euro up to 27 September 2010, when Portugal Telecom sold its former investment in Brasilcel.

42.4. Other movements

In the year ended 31 December 2011, other movements of provisions and adjustments include primarily:

• The write-off of trade receivables that were previously fully adjusted for;
• The impact of the unfavourable resolution of certain civil claims against Oi, as a result of which this company made payments amounting to Euro 62 million and used judicial deposits of Euro 35 million, which more than offset the financial effect on outstanding provisions.
• The impact of the reclassification of the asset retirement obligation to the caption ''Other non-current liabilities''.

In the year ended 31 December 2010, other movements of provisions and adjustments include primarily:

• The write-off of trade receivables that were previously fully adjusted for, which amounted to Euro 89 million and include Euro 52 million and Euro 34 million related to discontinued operations and the operating segment telecommunications in Portugal, respectively;
• Other movements of provisions for litigation, which amounted to Euro 28 million and include Euro 19 million related to discontinued operations and Euro 7 million regarding the unfavourable resolution on the arbitral claim filed by Oni SGPS, S.A. against TMN (Note 49).

• (ii) As at 31 December 2011, this caption includes primarily an account payable to the non-controlling shareholders of Brasil Telecom amounting to Euro 86 million (Notes 1 and 22), following the approval of a distribution of redeemable shares.
• (iii) This caption includes asset retirement obligations recorded by TMN (Euro 32 million), which as at 31 December 2010 were included under the caption ''Provisions'', and Oi (Euro 22 million).
• (iv) The increase in this caption is explained primarily by the proportional consolidation of Oi, including mainly as at 31 December 2011 an account payable to the non-controlling interests of the Oi Group, amounting to Euro 23 million, in connection with reverse stock splits undertaken in previous years. According to these transactions, the shares issued by various companies were grouped in lots, with each lot exchanged for a new share. Because certain shareholders did not have a sufficient number of shares to receive a new share in exchange, an auction of the shares not attributed/exchanged was undertaken and each company recognized the amount received in this auction as a payable to the former shareholders, which will be reduced to the extent that they request those amounts. In addition, this caption also includes the fair value of derivative financial instruments, amounting to Euro 8.0 million as at 31 December 2011 and Euro 3.4 million as at 31 December 2010 (Note 45.2).

44. Shareholders' Equity

44.1. Share capital

Portugal Telecom's fully subscribed and paid-in share capital as at 31 December 2010 amounted to Euro 26,895,375, represented by 896,512,500 shares with a nominal value of three cents of Euro each, with the following distribution:

• 896,512,000 Ordinary Shares; and
• 500 Class A Shares.

At the Portugal Telecom's General Meeting of Shareholders held on 26 July 2011, it was approved an amendment to the Company's Bylaws that eliminated the special rights granted to the 500 Class A shares (the so-called ''golden share''). Consequently, after this approval, these shares do not have any special right.

44.2. Treasury shares

As at 31 December 2011 and 2010, this caption includes equity swaps entered into by Portugal Telecom over 20,640,000 treasury shares with an exercise price of Euro 8.63 per share, totaling an amount of Euro 178,071,827 that was recognized as an effective acquisition of treasury shares. As at 31 December 2011, Portugal Telecom had recorded a financial liability related to these equity swaps amounting to Euro 93,767,521, following the repayment of Euro 84,304,306 in 2011 (Note 38.4).

Additionally, as at 31 December 2011, this caption includes Portugal Telecom's own shares that were acquired by Oi under the strategic partnership between Portugal Telecom and Oi (Note 1), under which it was envisaged that Oi would acquire up to 10% of the Portugal Telecom share capital. Up to 31 December 2011, Oi acquired 64,557,566 shares of Portugal Telecom, representing an interest of 7.2%. The Company's share in this investment, held indirectly through Bratel Brasil, was classified in the Consolidated Statement of Financial Position as treasury shares and amounted to Euro 148,311,037 (Note 1), corresponding to the acquisition price of the shares.

44.3. Legal reserve

Portuguese law provides that at least 5% of each year's profits must be appropriated to a legal reserve until this reserve equals the minimum requirement of 20% of share capital. This reserve is not available for distribution to shareholders but may be capitalized or used to absorb losses, once all other reserves and retained earnings have been exhausted. As at 31 December 2011, the legal reserve is already fully incorporated, corresponding to more than 20% of share capital.

44.4. Reserve for treasury shares

The reserve for treasury shares relates to the recognition of a non-distributable reserve equivalent to the nominal value of the shares cancelled or to the acquisition cost of treasury shares held by the Company. This reserve has the same legal regime as the legal reserve. As at 31 December 2011 and 2010, this reserve relates to shares cancelled on 20 December 2007, 24 March 2008 and 10 December 2008.

45. Financial instruments

45.1. Financial risks

Portugal Telecom is primarily exposed to (i) market risks related to changes in foreign currency exchange rates and interest rates, (ii) credit risks and (iii) liquidity risks. The main objective of Portugal Telecom's financial risk management is to reduce these risks to an acceptable level. The purpose of the financial instruments entered into by Portugal Telecom is to reduce the risk of exposure to changes in interest and exchange rates.

The contracting of these derivatives is made after careful analysis of associated risks and rewards, taking into consideration information obtained from different institutions. These transactions are subject to authorization from Portugal Telecom's Executive Committee. The fair value of these

45. Financial instruments (Continued)

derivatives is determined on a regular basis, based on market information, in order to assess the economic and financial implications of different scenarios. The Executive Committee monitors regularly these financial risks.

Regarding Oi's financial instruments, which represent the major part of the Group's total financial instruments, the Executive Committee of Oi annually agrees with the Board of Directors to follow a specific risk guideline, which is equivalent to the worst expected impact on financial income (expenses) of the net income of the Oi Group, with a 95% level of confidence. To ensure a proper risk management in accordance with the risk guideline, Oi may enter into hedging instruments, including derivative transactions such as swaps, currency forwards and options. Oi and its subsidiaries do not use derivative instruments for other purposes.

45.1.1. Foreign currency exchange rate risk

Foreign currency exchange rate risks relate mainly to Portugal Telecom's investments in Brazil and other foreign operations, and to debt denominated in currencies different from the functional currency of the country where the borrowing company operates.

As at 31 December 2011, the risks related to the Company's investments in foreign currencies relate primarily to its investments in Oi and Contax. As at 31 December 2011, the net exposure (assets minus liabilities, net of non-controlling interests) to Brazil amounted to R\$ 8,667 million (Euro 3,587 million as at the Euro/Real exchange rate prevailing at 31 December 2011). Portugal Telecom does not have in place any financial instrument to hedge the exchange risk on investments in foreign companies.

As at 31 December 2011, the risks related to debt denominated in currencies different from the Group companies' functional currencies were basically related to foreign currency debt contracted by Oi and its subsidiaries, which represented about 29.9% of its gross debt. In order to minimize this risk, Oi entered into foreign exchange hedging contracts with financial institutions. Out of Oi's debt denominated in foreign currency as at 31 December 2011, 96.2% is protected through exchange rate swaps, currency forwards and foreign currency-denominated cash applications, while the remaining 3.8%, amounting to R\$ 319 million (Euro 34 million, corresponding to Portugal Telecom's 25.6% stake proportionally consolidated) is exposed to the risk of the change in the USD/BRL exchange rates.

The effects of hypothetical changes of relevant risk variables on income statement and shareholders' equity of Portugal Telecom are as follows:

• The impact of the appreciation (devaluation) of the Real against the Euro by 0.1, from 2.42 to 2.32 (2.52), would be an increase (decrease) in Portugal Telecom's net assets as at 31 December 2011 by approximately Euro 155 million (Euro 143 million), which corresponds to currency translation adjustments on Brazilian investments;
• All other variables being equal, the impact of the appreciation (devaluation) of the US Dollar against the Real by 0.1 during 2011, would have been an increase (reduction) in the contribution of Oi to Portugal Telecom's financial expenses by approximately Euro 0.1 million, as a result of

45. Financial instruments (Continued)

the portion of Oi's debt denominated in foreign currencies that is not protected through derivative financial instruments or cash applications denominated in foreign currencies;

• Most of non-derivative financial assets and liabilities are denominated in the functional currency either directly or indirectly through the use of derivatives. Therefore, changes in exchange rates would have no material effects on the income statement and shareholders' equity of the companies where those assets and liabilities are recorded.

45.1.2. Interest rate risk

Interest rate risk basically impact the Group's financial expenses and income on the floating interest rate debt and cash applications. As at 31 December 2011, Portugal Telecom is exposed to this risk primarily in the Euro zone and in Brazil. The Group's consolidated debt is subject to floating interest rates based on the following rates: (1) Euribor, applicable for certain loans obtained in the Euro zone; (2) TJLP, a long-term interest rate set by the National Monetary Council in Brazil; (3) IPCA, a Consumer Price Index published by the Brazilian Institute for Geography and Statistics; (4) CDI, an interbank rate for Brazilian real-denominated debt; and (5) Libor, an interbank rate for US dollar-denominated debt. With the purpose of reducing the impact of these risks, the Group entered into interest-rate swaps, swapping floating rate into fixed rate debt.

As at 31 December 2011, considering the effects of derivative transactions, 38.9% of consolidated gross debt, amounting to approximately Euro 4,779 million, was subject to floating interest rates. In addition, total consolidated cash and cash equivalents plus short-term investments, amounting to Euro 5,668 million as at 31 December 2011, also bears interest at floating rates, thus eliminating the interest rate risk on gross debt. Accordingly, the Group's net exposure to floating interest rates amounted to a net cash position of approximately Euro 889 million as at 31 December 2011. If all market interest rates had been lower (higher) by 1% during the year ended 31 December 2011, net interest expenses would have been higher (lower) by an amount of approximately Euro 2 million (Euro 2 million).

Interest rate risks also result from the exposure to changes in the fair value of Portugal Telecom's long term fixed-rate debt due to changes in market interest rates.

45.1.3. Credit risk

Credit risk relates mainly to the risk that a third party fails on its contractual obligations, resulting in a financial loss to the Group. Portugal Telecom is subject to credit risks in its operating and treasury activities.

Credit risks in operations relate basically to outstanding receivables from services rendered to our customers (Notes 26 and 27). The Group does not have any significant credit risk exposure to any single customer, since trade receivables consist of a large number of customers, spread across several businesses and geographical areas. These risks are monitored on a business-to-business basis, and Portugal Telecom's management of these risks aims to: (a) limit the credit granted to customers, considering the profile and the aging of receivables from each customer; (b) monitor the evolution of

45. Financial instruments (Continued)

the level of credit granted; (c) perform an impairment analysis of its receivables on a regular basis; and (d) assess the market risk where the customer is located. Accordingly, the criteria used to compute these adjustments is based on these factors. The movement of these adjustments for the years ended 31 December 2011 and 2010 is disclosed in Note 42. As at 31 December 2011, the Group's accounts receivables which were neither adjusted nor deferred and were already due with maturities above one hundred and eighty days amounted to approximately Euro 88 million, as compared to Euro 111 million as at 31 December 2010. As at 31 December 2011, the Group believes that there was no further credit adjustment required in excess of the adjustments for accounts receivable included in Note 42.

Risks related to treasury activities result mainly from the cash deposits on investments made by the Group. In order to dilute these risks, Portugal Telecom's policy is to invest its cash for short time periods, entering in agreements with reputable financial institutions and diversifying counterparties.

45.1.4. Liquidity risk

This risk may occur if the sources of funding, including cash balance, operating cash inflows, divestments, credit lines and cash flows obtained from financing operations, do not match the Group's financing needs, such as operating and financing outflows, investments, shareholder remuneration and debt repayments. Based on the cash flows generated by operations and on the available cash plus undrawn committed standby facilities and underwritten commercial paper agreements, as detailed below, Portugal Telecom concluded that the Group is able to meet its estimated obligations, based on the available information up to date regarding several factors exogenous to its businesses.

In order to mitigate liquidity risks, the Group seeks to maintain a liquidity position and an average maturity of debt that allows it to repay its short-term debt and, at the same time, pay all its contractual obligations, as mentioned below. As at 31 December 2011, the amount of available cash, excluding cash from the international operations, plus the undrawn amount of Portugal Telecom's underwritten commercial paper lines (cash immediately available upon a 2 or 3-day notice) and Portugal Telecom's committed standby facilities amounted to Euro 5,095 million, a reduction from Euro 6,297 million as at 31 December 2010. This reduction reflects primarily the investments made in the acquisition of the interests in Oi and Contax and dividends paid during the year, which more than offset the impacts resulting from the third and last instalment received under the disposal of Vivo and certain new financings obtained in 2011. The average maturity of Portugal Telecom's net debt as at 31 December 2011 is 5.9 years.

The capital structure of Portugal Telecom is managed in order to ensure that its businesses will be able to continue as a going concern and maximize the return to shareholders. The capital structure of the Group includes debt (Note 38), cash and cash equivalents, short-term investments (Note 25) and equity attributable to equity holders of the parent, comprising issued capital, treasury shares, reserves and accumulated earnings (Note 44). The Group reviews periodically its capital structure considering the risks associated with each of the above mentioned classes of the capital structure.

As at 31 December 2011, the gearing ratio, determined as the proportion of net debt (debt minus cash and cash equivalents and short-term investments) to net debt plus equity increased to 63.9%, from 31.3% as at 31 December 2010, primarily as a result of the increase in net debt resulting from the

45. Financial instruments (Continued)

investments in Oi and Contax completed on 28 March 2011. The equity plus long-term debt to total assets ratio decreased from 71.6% to 55.5% as at 31 December 2011.

The following table presents Portugal Telecom's maturity of expected contractual obligations and commercial commitments as at 31 December 2011, on a consolidated basis:

	Total	Less than one year	One to three years	Three to five years	More than five years
			Euro million
Indebtedness	12,357.0	3,304.2	3,590.9	1,578.7	3,883.1

Post retirement benefits payments(ii)	1,226.2	184.8	327.7	253.2	460.6

Unconditional financial commitments(iv)	322.7	322.7	—	—	—
Operating leases (Note 12)	168.4	45.8	43.6	32.4	46.7
Total contractual obligations	17,460.6	4,654.7	5,123.9	2,537.0	5,145.0

(i) Portugal Telecom's expected obligations related to interest on indebtedness are based on the Company's indebtedness as at 31 December 2011 assuming that repayments will be made on scheduled dates and considering assumptions regarding interest rates on Portugal Telecom's floating rate debt. Therefore actual interest obligations could vary significantly from these amounts depending on future refinancing activities and market interest rates. These obligations relate exclusively to interest expenses on gross debt and as such do not include any interest income on cash and cash equivalents and short-term investments,

• (ii) This caption includes primarily amounts corresponding to the undiscounted payments to be made by PT Comunica¸coes related to salaries due to pre-retired and suspended employees and to ˜ expected contributions to the funds. For the unfunded portion and for calculation purposes, Portugal Telecom has assumed a linear contribution over the coming years. The total amount regarding Portuguese operations differs from the net accrued post retirement liability recognized in the Consolidated Statement of Financial Position primarily because the latter amount relates to the discounted unfunded obligations. In addition, this caption also includes expected contributions to cover the actuarial deficit of BrTPREV Oi's pension plan.
• (iii) This caption includes (1) estimated bi-annual fees due to ANATEL under Oi's concession agreements equal to 2.0% of the net operating revenues of Brasil Telecom, which are derived from the provision of local fixed-line services (excluding taxes and social contributions), and (2) payments due to ANATEL and ANACOM as at 31 December 2011 for radio frequency licenses (Note 39).
• (iv) Unconditional purchase obligations relate basically to contractual agreements with suppliers for the acquisition of tangible fixed assets and stocks, including all amounts related to the acquisition of network assets, telecommunications equipment and terminal equipments.

45. Financial instruments (Continued)

In addition, Portugal Telecom has announced a remuneration package proposal that includes an ordinary cash dividend of Euro 0.65 per share for the fiscal year ending 31 December 2011, of which Euro 0.215 per share was paid in January 2012 and the remaining Euro 0.435 per share is subject to approval in the Annual Shareholders' Meeting to be held on 27 April 2012.

45.2. Derivative financial instruments

⁽i) Accounts receivable and payable include certain items which do not meet the requirements to be classified as either financial assets or financial liabilities, respectively, and therefore were excluded from these captions.

45. Financial instruments (Continued)

IFRS 7 defines fair value as the amount for which an asset could be exchanged, or a liability settled, between knowledgeable, willing parties in an arm's length transaction on measurement date. In addition, this standard refers that the fair value must be based on the assumptions that market participants would consider in pricing an asset or a liability, and establishes a hierarchy that prioritizes the information used to build such assumptions. The fair value measurement hierarchy attaches more importance to available market inputs (observable data) and a less weight to inputs based on data without transparency (unobservable data). Except for debt, the fair value of which is disclosed in Note 38, and for derivatives, which are recorded at fair value, the fair value of the remaining financial assets and liabilities is similar to their carrying amounts. The fair value of financial instruments was determined as follows:

• Except for fixed rate notes amounting to Euro 50 million and the non-convertible bonds obtained by the Oi Group and its controlling shareholders totalling Euro 1,950 million (Note 38), which fair value was determined based on a discounted cash flow methodology, equivalent to the level 2 in the fair value hierarchy defined by IFRS 7 (observable inputs other than quoted prices), the fair value of the remaining convertible and non-convertible bonds was obtained based on quoted prices in active markets, which is equivalent to the level 1 in the fair value hierarchy (unadjusted quoted prices in active markets);
• For the bank loans, the fair value was determined internally based on a discounted cash flow methodology using inputs that are observable in the market, equivalent to the level 2 in the fair value hierarchy mentioned above;
• For the liability related to equity swaps on treasury shares, the fair value of these instruments, representing a negative amount of Euro 7.7 million as at 31 December 2011, was determined externally based on the difference between the exercise price of these equity swaps and Portugal Telecom's stock price as of that date, equivalent to the level 2 in the fair value hierarchy mentioned above;
• For derivative financial instruments contracted, the fair value was determined externally based on a discounted cash flow methodology using inputs that are observable in the market, equivalent to the level 2 in the fair value hierarchy mentioned above;
• For other loans not mentioned above, the fair value was determined internally based on a discounted cash flow methodology using inputs that are observable in the market, equivalent to the level 2 in the fair value hierarchy mentioned above.

Portugal Telecom considers that the main assumption used in the discounted cash flow methodology prepared internally relates to the discount rate, which for financial instruments contracted by Portugal Telecom or any of its 100%-owned subsidiaries with maturities between 1 month and 10 years vary between 5.8% and 11.2%. In addition, Portugal Telecom also used forward interest and exchange rates obtained directly through market information, taking into consideration the maturity and currency of each financial instrument.

(Amounts expressed in Euros, except where otherwise stated)

46. Guarantees and financial commitments

	Euro
Bank and other guarantees given by Oi(i)	871,729,739
Bank and other guarantees given by Portuguese companies to courts
and tax authorities(ii)	273,675,513
Bank guarantees given to other entities:
On behalf of PT Comunica¸coes(iii) ˜	21,791,615
On behalf of TMN(iv)	17,206,927
Other bank guarantees	4,787,157
Total	1,189,190,951

⁽i) Bank and other guarantees given by Oi intend primarily to guarantee commitments arising from lawsuits, contractual obligations, and biddings with ANATEL.

• (ii) Bank and other guarantees given by Portuguese companies to courts and tax authorities include primarily Euro 267 million related to the tax assessments received by Portugal Telecom regarding the years 2005 to 2008, where the main issue raised by the tax authorities relates to the deductibility of certain financial costs incurred in those years and of a capital loss occurred in 2006 following the liquidation of a subsidiary, as explained in Note 49. In accordance with Portuguese tax legislation, the Company has presented these guarantees and submitted a claim or an appeal to the tax authorities in order to be able to hold open discussions with the tax authorities and avoid the payment of a given tax assessment. In Portugal, these two conditions are required and must be complied with before the process can continue, regardless of the amount of the tax assessment or the likelihood of success of the appeal or the claim.
• (iii) Bank guarantees given on behalf of PT Comunica¸coes were presented essentially to the ˜ following entities: (1) Municipal Authorities, which relate mainly to the payment of taxes and other fees in connection with Portugal Telecom's use of public rights-of-way; and (2) Anacom, which relate mainly to an open contest for granting the right of use national frequencies for the television service.
• (iv) Bank guarantees given on behalf of TMN include primarily a guarantee presented to Anacom amounting to Euro 15 million in connection with the LTE license acquired in 2011.

As at 31 December 2011, Portugal Telecom had given guarantees amounting to Euro 439 million in favour of the European Investment Bank in connection with bank loans obtained from this bank (Note 38.3). In addition, certain loans obtained by the Oi Group, totalling Euro 715 million, are collateralized by either its receivables or by guarantees presented by its parent company or its subsidiaries.

Under the cross-border lease transactions entered into by TMN (Notes 32 and 43), the Company has agreed with financial institutions to issue letters of credit for the benefit of the trustee (the entity that financed the operation). As at 31 December 2011, the total drawing amount under these letters of

46. Guarantees and financial commitments (Continued)

credit is US\$ 5 million, equivalent to Euro 4 million at the exchange rate prevailing at year end. In addition, Portugal Telecom had bank deposits amounting to Euro 3 million as at 31 December 2011, the use of which was restricted due to these cross-border lease transactions.

47. Consolidated Statement of Cash Flows

(a) Cash flows from operating activities relating to continuing operations

Following the acquisition of the investments in Oi and Contax completed on 28 March 2011, the cash flows from these companies were proportionally consolidated in Portugal Telecom's Statement of Cash Flows as from 1 April 2011, which explains the increases occurred in 2011 in cash receipts from customers, payments to suppliers and employees and payments of indirect taxes.

(b) Payments relating to income taxes

The increase in this caption in 2011 is primarily explained by (1) the impact of the proportional consolidation of Oi and Contax as from 1 April 2011 (Euro 62 million), and (2) withholding taxes paid by Bratel Brasil and PT Moveis related to interest income obtained from the financial applications ´ related to the proceeds received from the disposal of Vivo. The reduction in this caption in 2010, as compared to the year 2009, is primarily explained by lower payments on account at Portuguese operations, which amounted to Euro 48 million in 2010 and Euro 108 million in 2009, and a higher cash receipt in 2010 regarding the last installment of the 2009 income taxes (Euro 59 million), as compared to the previous year (Euro 11 million), following the decrease in tax earnings from operations in Portugal. This effect was partially offset by increases in income taxes paid by certain foreign operations, including GPTI which was consolidated as from 1 March 2010.

(c) Payments relating to indirect taxes and other

This caption includes primarily payments related to the expenses recorded in the caption ''Indirect taxes'' (Note 13) of the Consolidated Income Statement, and also payments and collections of Value-Added Tax in Portugal.

(d) Short-term financial applications

These captions include basically cash payments from new short-term financial applications entered into and cash receipts from the short-term applications matured. Net cash payments amounted to Euro 204,168,957 and Euro 320,167,898 in 2011 and 2010, respectively, as compared to net cash receipts of Euro 13,204,259 in 2009.

(e) Cash receipts from financial investments

In the year ended 31 December 2011, this caption includes basically the proceeds obtained from the disposal of the investment in UOL, amounting to Euro 155.5 million (Note 33). In the year ended 31 December 2009, this caption includes primarily the total proceeds received by Portugal Telecom in

(f) Cash receipts (payments) resulting from interest and related income (expenses)

The significant increase in 2011 relates primarily to the impact of the proportional consolidation of Oi and Contax as from 1 April 2011 (Euro 185 million), partially offset by interest income received during the first quarter of 2011 on financial applications related to the proceeds received from the disposal of Vivo.

c) Other

During the years ended 31 December 2011 and 2010, fixed remunerations of board members, which were established by the Remunerations Committee, amounted to Euro 5.32 million and Euro 6.68 million, respectively.

Under the terms of the remuneration policy established by the Remunerations Committee, executive board members are entitled to receive: (i) annual variable remuneration (''AVR'') related to the performance achieved in the year and payable in the following year, except for the amount in excess of 50% of the total variable remuneration attributed in the year, which payment is deferred for a period of 3 years, and (ii) variable remuneration related to the medium term performance (''VRMT''), which payment is deferred for a period of 3 years. In 2011, the annual variable remuneration of 2010 paid to the five executive board members amounted to Euro 2.34 million, and in 2010, the annual variable remuneration of 2009 paid to the seven executive board members amounted to Euro 3.52 million. In 2011 and 2010, there were no payments related to the VRMT and, under the terms of the approved remuneration policy of executive board members, the deferred payment of AVR and VRMT amounted to Euro 4.28 million as at 31 December 2011, which is conditional on the positive performance of the Company under the terms of the remuneration policy in place. On an annual basis, Portugal Telecom recognizes an accrual for the variable remunerations.

Following the recommendation of some shareholders at the 2011 annual general meeting and based on a proposal of the Evaluation Committee, the Remunerations Committee approved an extraordinary variable remuneration payable to the Chairman and five executive board members regarding their performance under the Vivo transaction (Note 1) and the acquisition of a strategic investment in Oi and Contax (Note 1). Under the terms of the remuneration policy of board members, in 2011 was paid to the chairman and five executive board members 50% of the above mentioned extraordinary variable remuneration amounting to Euro 2.55 million, and the payment of the remaining 50% was deferred for a period of 3 years, which is conditional on the positive performance of the Company under the terms of the remuneration policy in place. Following the Vivo transaction and based on a board of directors' recommendation, the executive committee approved in December 2010 the payment to the majority of Portugal Telecom's employees of an extraordinary variable remuneration totaling Euro 14 million.

Additionally, in connection with the strategic partnership entered into with Oi and Contax, six of Portugal Telecom's board members perform executive duties in these companies (entities jointly controlled by Portugal Telecom), having received in 2011 a total fixed compensation of Euro 1.21 million, which was established by the competent corporate bodies in accordance with local legislation.

During the years ended 31 December 2011 and 2010, fixed remuneration of Portugal Telecom's key employees amounted to Euro 5.6 million and Euro 6.9 million, respectively, and variable remuneration amounted to Euro 3.6 million and Euro 3.4 million, respectively.

In addition to the above mentioned remunerations, executive board members and key employees are also entitled to fringe benefits that are primarily utilized in their daily functions, in accordance with a policy defined for the Group. As at 31 December 2011, there were no board members entitled to post retirement benefits under the plans of PT Comunica¸coes and there were seven key employees of ˜ Portugal Telecom entitled to those benefits with the corresponding liability amounting to Euro 0.5 million as at 31 December 2011.

As at 31 December 2011, there was no share based payment program or termination benefit in place.

For additional information regarding the remunerations of board members and key employees, please read the Corporate Governance Report included in the Annual Report.

One of Portugal Telecom's non-executive board members is also executive director of ''Heidrick & Struggles—Consultores de Gestao, Lda'', which on the normal course of business rendered consultancy ˜ services to Portugal Telecom amounting to approximately Euro 1.2 million (excluding VAT) in 2011.

As at 31 December 2011, Portugal Telecom did not have any outstanding balances with board members or key employees.

49. Litigation

49.1. Consolidated legal proceedings and tax contingencies

a) Probable loss

As at 31 December 2011 and 2010, there were several claims, legal actions and tax contingencies against certain subsidiaries of the Group in which losses are considered probable in accordance with the definitions of IAS 37 Provisions, Contingent Assets and Contingent Liabilities. The Group, based on the opinion of its internal and external legal counsels, recorded provisions (Note 42) for those claims, legal actions and tax contingencies to cover its probable future cash outflows, as follows:

	2011	2010
	Euro
Civil claims	455,240,630	18,117,450
Labor claims	220,946,141	4,230,646
Other	4,274,712	4,915,363
Sub-total	680,461,483	27,263,459
Tax	163,444,761	54,761,153
Total	843,906,244	82,024,612

The increase occurred in the year ended 31 December 2011 is basically explained by the impact of the proportional consolidation of current and non-current provisions from Oi and Contax in Portugal Telecom's Statement of Financial Position as at 31 March 2011, amounting to Euro 213 million and Euro 594 million, respectively, totaling Euro 807 million (Note 49.3).

49. Litigation (Continued)

As at 31 December 2011, the effect of the proportional consolidation of Oi and Contax amounted to Euro 760 million (Note 49.3) and, excluding this effect, total consolidated legal proceedings and tax contingencies would have amounted to Euro 79 million (Note 49.2), as compared to Euro 82 million as at 31 December 2010.

b) Possible loss

As at 31 December 2011 and 2010, there were several claims, legal actions and tax contingencies against certain subsidiaries of the Group for which the likelihood of future cash outflows was considered possible based on the information provided by its legal counsels, and therefore are not provided for. The nature of these contingencies is as follows:

	2011	2010
	Euro
Civil claims	213,348,131	55,083,437
Labor claims	257,149,316	30,968,381
Other	18,492,008	35,996,745
Sub-total	488,989,455	122,048,563
Tax	1,969,003,002	43,380,565
Total	2,457,992,457	165,429,128

The increase occurred in the year ended 31 December 2011 relates basically to Oi and Contax, which had legal proceedings and tax contingencies for which loss was considered possible amounting to Euro 2,346 million as at 31 December 2011 and Euro 2,433 million as at 31 March 2011 (Note 49.3). Excluding the impacts of Oi and Contax, total legal proceedings and tax contingencies for which loss was considered possible totaled Euro 112 million (Note 49.2) as at 31 December 2011, as compared to Euro 165 million as at 31 December 2010.

49.2. Legal proceedings and tax contingencies against Portuguese subsidiaries and certain international operations

Excluding Oi and Contax (Note 49.3), consolidated legal proceedings and tax contingencies for which related losses were considered probable and possible, which are primarily related to Portuguese operations, amounted to Euro 79 million (Note 49.1) and Euro 112 million (Note 49.1) as at 31 December 2011, respectively, as compared to Euro 82 million and Euro 165 million, respectively. The following litigation processes relate to the main claims, legal actions and tax contingencies against Portuguese subsidiaries of the Group, some of which the Company considers, based on the opinion of its internal and external legal counsels and in accordance with the definitions of IAS 37, that related losses are remote, which therefore are not included in the amounts disclosed above.

49. Litigation (Continued)

a) Claims for municipal taxes and fees

Pursuant to a statute enacted on 1 August 1997, as an operator of a basic telecommunications network, Portugal Telecom was exempt from municipal taxes and rights-of-way and other fees with respect to its network in connection with its obligations under the Concession. The Portuguese Government has advised Portugal Telecom in the past that this statute confirmed the tax exemption under our Concession and that it will continue to take the necessary actions in order for PT Comunica¸coes to maintain the economic benefits contemplated by the Concession. At this time, ˜ Portugal Telecom cannot be sure that the Portuguese courts will accept that this statute resolves claims for municipal assessments and taxes for the period prior to its enactment.

In 1999, the municipality of Oporto filed a lawsuit claiming the payment of taxes and other fees in connection with the use by PT Comunica¸coes of public rights-of-way in 1998. The Lower Tax Court of ˜ Oporto ruled in favour of PT Comunica¸coes in March 2003, declaring the regulations of the ˜ Municipality of Oporto, under which such taxes and other fees were deemed to be owed by PT Comunica¸coes, to be unconstitutional. The Municipality of Oporto subsequently appealed this decision ˜ to the Administrative Central Court, and then PT Comunica¸coes submitted its response thereto. This ˜ appeal was partially favorable to PT Comunica¸coes, but the Municipality of Oporto appealed to the ˜ Supreme Administrative Court and this appeal is pending decision.

If this claim is upheld against PT Comunica¸coes, other municipalities might seek to make or renew ˜ their claims against PT Comunica¸coes. Portuguese law provides for a four-year statute of limitations for ˜ claims for taxes or other similar governmental charges. The statute of limitation for taxable events that occurred prior to 1 January 1998 is five years. Since the statute of limitations for such claims has expired, Portugal Telecom does not expect that any further claims will be made against PT Comunica¸coes, but Portugal Telecom cannot be certain about this. ˜

Law 5/2004, dated 10 February 2004, established a new rights-of-way regime in Portugal whereby each municipality may establish a fee, up to a maximum of 0.25% of each wireline services bill, to be paid by the customers of those wireline operators which network infrastructures are located in each such municipality. This regime was implemented in 2005 but does not affect the lawsuit described above based on the former statute. Meanwhile, Decree-Law 123/2009, dated 21 May 2009, clarified that no other tax should be levied by the municipalities in addition to the tax established by Law 5/2004. On 6 October 2010, in Case 0363/10, this interpretation was confirmed by the Supreme Administrative Court of Portugal.

Some municipalities however, continue to persive that the Law 5/2004 does not expressly revoke other taxes that the municipalities wish to establish, because Law 5/2004 is not applicable to the public municipality domain. Currently, there are legal actions filed by some municipalities against PT Comunica¸coes regarding this matter. ˜

b) Regulatory Proceedings

Portugal Telecom Group companies are regularly subject to regulatory inquiries and investigations involving their operations. In addition, ANACOM (the telecoms regulator), the European Commission,

49. Litigation (Continued)

and the Autoridade da Concorrencia (the competition authority) regularly make inquiries and conduct ˆ investigations concerning compliance with applicable laws and regulations. Current inquires and investigations include several investigations by Autoridade da Concorrencia related to PT ˆ Comunica¸coes and TMN for alleged anti-competitive practices in the Digital Terrestrial Television and ˜ public mobile telephone markets, respectively. Portugal Telecom considers that group companies have consistently followed a policy of compliance with all relevant laws. The Group continually reviews commercial offers in order to reduce the risk of competition law infringement. However, if group companies are found to be in violation of applicable laws and regulations in these or other regulatory inquiries and investigations, they could become subject to penalties, fines, damages or other sanctions. It is however permitted under Portuguese law to appeal any adverse decision to the Courts. The appeal will suspend the decisions of Autoridade da Concorrencia. ˆ

In April 2007, Autoridade da Concorrencia accused PT Comunica¸ ˆ coes of alleged abuse of ˜ dominant position for granting discriminatory discounts on lease lines. In response to this accusation, PT Comunica¸coes contested the alleged by Autoridade da Concorr ˜ encia. However, on 1 September ˆ 2008, Autoridade da Concorrencia imposed a fine of Euro 2.1 million on PT Comunica¸ ˆ coes. On ˜ 29 September 2008, PT Comunica¸coes appealed to the Commerce Court of Lisbon and, on 29 February ˜ 2012, the Commerce Court of Lisbon cleared PT Comunica¸coes on the fine imposed by Autoridade da ˜ Concorrencia. Portugal Telecom, based on the opinion of its internal and external legal counsels, had ˆ not recorded any provision for this matter.

In September 2009, Portugal Telecom was notified of the decision of Autoridade da Concorrencia ˆ in the misdemeanour proceedings no. 05/03 further to which Autoridade da Concorrencia imposed a ˆ fine of Euro 45 million for an alleged abuse of dominant position relating to the application, between 22 May 2002 and 30 June 2003, of the versions 11 to 15.9 of the wholesale offer ''Rede ADSL PT''. On 29 September 2009, Portugal Telecom appealed to the Commerce Court of Lisbon. This appeal suspended the decision of Autoridade da Concorrencia. Portugal Telecom disagreed of the decision ˆ taken and understood that, even if a sanction would be justified, which was not the case, the fine imposed exceeded in an absolutely incomprehensible manner the maximum limit allowed by the applicable legal framework. In 2011, Portugal Telecom was notified of the decision of the Commerce Court of Lisbon that declared the termination of this proceeding for prescription purposes, as from 30 June 2011. Portugal Telecom, based on the opinion of its internal and external legal counsel, had not recorded any provision for this matter.

In April 2006, the European Commission sent a formal request to the Portuguese Government to abandon the special rights it held as the sole owner of Portugal Telecom's Class A Shares (the so-called ''golden share''). The European Commission believes that the special powers granted to the Portuguese Government through the sole ownership of the Class A Shares acted as a disincentive for investment by other EU member states in a manner that violates European Community Treaty rules. As at 31 January 2008, the European Commission informed that the case over special rights held by the Portuguese State in Portugal Telecom was referred to the European Court of Justice. On 8 July 2010, the European Court of Justice decided that the special rights held by the Portuguese State in Portugal Telecom were in breach of the European Community Treaty rules and Law. The General Shareholders' Meeting held

49. Litigation (Continued)

on 26 July 2011, approved an amendment to the Company's Bylaws that eliminated the special rights granted to the 500 Class A shares, as mentioned in Note 44.1.

On 19 January 2011, the European Commission opened an investigation into an agreement between Telefonica and Portugal Telecom allegedly not to compete on the Iberian telecommunications ´ markets. In October 2011, Portugal Telecom was notified of a Statement of Objections sent by the European Commission to Portugal Telecom and Telefonica on this matter. The Statement of Objections only covers the alleged cooperation between the two companies after the Vivo transaction. In response to the Statement of Objections, Portugal Telecom contested the alleged by the European Commission. The sending of a Statement of Objections does not prejudge the final outcome of the investigation.

c) Other Legal Proceedings

In March 2004, TV TEL Grande Porto—Comunica¸coes, S.A., or TVTEL, a telecommunications ˜ company based in Oporto, filed a claim against PT Comunica¸coes in the Lisbon Judicial Court. ˜ TV TEL alleged that, since 2001, PT Comunica¸coes has unlawfully restricted and/or refused access to ˜ its telecommunication ducts in Oporto, thereby undermining and delaying the installation and development of TV TEL's telecommunications network. TV TEL alleges that PT Comunica¸coes ˜ intended to favor both itself and CATVP—TV Cabo Portugal, S.A, subsidiary of PT-Multimedia and at ´ the time a direct competitor of TV TEL. TV TEL is claiming an amount of approximately Euro 15 million from Portugal Telecom for damages and losses allegedly caused and yet to be sustained by that company as a result of the delay in the installation of its telecommunications network in Oporto. In addition, TV TEL has demanded that PT Comunica¸coes be required to give full access to ˜ its ducts in Oporto. PT Comunica¸coes submitted its defence to these claims in June 2004, stating that ˜ (1) TV TEL did not have a general right to install its network in PT Comunica¸coes's ducts, (2) all of ˜ TV TEL's requests were lawfully and timely responded to by PT Comunica¸coes according to its general ˜ infra-structure management policy, and (3) TV TEL's claims for damages and losses were not factually sustainable. The trial was concluded in 2011 and the parties wait for the judicial decision.

In March 2011, Optimus—Comunica¸coes S.A. (''Optimus'') filed a claim against Portugal Telecom ˜ in the Judicial Court of Lisbon for the payment of approximately Euro 11 million and, in October 2011, Onitelecom—Infocomunica¸coes, S.A (''Oni'') filed a claim against Portugal Telecom in the same ˜ court for the payment of approximately Euro 1.5 million, both related to the proceeding of the Autoridade da Concorrencia that terminated in 2011 for prescription purposes, in relation to which ˆ Autoridade da Concorrencia had imposed a fine to Portugal Telecom of approximately Euro 45 million, ˆ as referred to above. Optimus and Oni sustained their position by arguing that suffered losses and damages as a result of Portugal Telecom's conduct. The Company countered all the arguments presented by Optimus and Oni and, based on the opinion of its internal and external legal counsel, had not recorded any provision for this matter.

In December 2008, Oni SGPS, SA, SA (''Oni'') filed an arbitral claim against TMN in the Centre of Commercial Arbitration of the Chamber of Commerce and Industry of Lisbon for the reimbursement of more than Euro 36 million, as a result of the non fulfilment of the national roaming agreement celebrated between TMN and Oni Way—Infocomunica¸coes, SA. TMN submitted its defence ˜

49. Litigation (Continued)

to this claim in February 2009, namely stating that Oni does not bring any facts that may support its claim other than its own responsibility or the risks behind Oni Way business. In February 2010, the Centre of Commercial Arbitration ruled a final decision, and TMN was condemned to pay an amount of Euro 6.9 million (Note 42). The Company had recorded a provision for this legal action as at 31 December 2009, and subsequently paid this amount in 2010.

d) Tax contingencies

There are some tax claims against certain Portuguese subsidiaries of the Group which relate primarily to the deductibility of certain financial costs incurred between 2004 and 2009 (Euro 173 million) and of a capital loss occurred in 2006 following the liquidation of a subsidiary (Euro 59 million). Portugal Telecom already received tax assessments regarding these matters for all the years mentioned above and presented bank guarantees to the tax authorities for the years 2005 to 2007 totalling Euro 267 million (Note 46). As at 31 December 2011, Portugal Telecom strongly disagrees with these assessments and considers, based on the opinion of its tax advisors, that there are solid arguments to oppose the position of the tax authorities, and therefore did not consider the losses related to these tax contingencies as either probable or possible.

As at 31 December 2011 and 31 March 2011, the nature and detail of the main legal proceedings and tax contingencies against Oi, Contax and its controlling shareholders, for which the risk of loss was deemed probable and therefore are fully provided for, are as follows:

(i) Civil contingencies

(a) Corporate Law

As successor to CRT, which was acquired in July 2000, Oi is subject to various civil claims filed against that entity, namely several claims filed by users of telephone lines in the State of Rio Grande do Sul. CRT entered into financial interest agreements with its fixed-line subscribers. Under these financial interest agreements, customers had the right to subscribe to a number of

49. Litigation (Continued)

CRT shares, being the number of shares to be issued to each subscriber determined based on a formula that divided the cost of the fixed-line subscription by the book value of CRT's shares. Beginning in June 1997, certain of CRT's fixed-line subscribers began to file suits in which they claimed that the calculation used by CRT to arrive at the number of shares to be issued pursuant to the financial interest agreements was incorrect and resulted in the claimants receiving too few shares.

In addition, as successor to Telecomunica¸coes do Mato Grosso do Sul S.A. (''Telems''), ˜ Telecomunica¸coes de Goi ˜ as S.A. (''Telegoi ´ as'') and Telecomunica¸ ´ coes do Mato Grosso S.A. ˜ (''Telemat''), operating companies acquired by Brasil Telecom Holding in the privatization of Telebras and which were subsequently merged into Oi, Oi is subject to various civil claims in ´ connection with telephone programs (Community Telephone Programs) established in the States of Mato Grosso do Sul, Goias and Mato Grosso. ´

Brasil Telecom, based on the decisions of the court of justice issued in 2009, considers the risk of loss regarding these proceedings as probable. Currently, the provisions for these lawsuits are based on (i) several legal interpretations, (ii) the number of ongoing lawsuits by matter discussed and (iii) the average amount of historical losses, broken down by matter (including all procedural costs).

At the end of 2010, the website of the Superior Court of Justice (STJ) disclosed news that this court had set compensation criteria to be adopted by Brasil Telecom to the benefit of the shareholders of the former CRT for those cases in which new shares, possibly due, could not be issued because of the sentence issued. According to this court news, which do not correspond to a final decision, the potential compensation (conversion of the obligation into cash) must be based on: (i) the definition of the number of shares that each claimant would be entitled to, measuring the capital invested at the book value per share as reported in the company's monthly trial balance on the date it was paid-in; (ii) the number of shares determined shall be multiplied by its quotation on the stock exchange at the closing of the trading day the final and unappealable decision is issued, when the claimant becomes entitled to sell or dispose of the shares, and (iii) the result obtained must be adjusted for inflation from the trading day of the date of the final and unappealable decision, plus legal interest since notification. In the case of succession, the benchmark amount will be the stock market price of the successor company.

As at 31 December 2011, Oi recorded provisions in the amount of R\$2,350 million for those claims in respect of which it deemed the risk of loss as probable, as compared to R\$2,444 million as at 31 March 2011.

(b) ANATEL estimates and fines

Oi received various notifications from ANATEL, mainly for not meeting certain goals or obligations set out in the General Plan on Universal Service or in the General Plan on Quality Goals, such as responding to complaints relating to billing errors, requests for service repairs on a timely basis and requests from locations with collective or individual access. As at 31 December

49. Litigation (Continued)

2011, Oi recorded provisions in the amount of R\$941 million for those claims in respect of which it deemed the risk of loss as probable, as compared to R\$850 million as at 31 March 2011.

(ii) Labor contingencies

Oi is a party to a large number of labor claims arising out of the ordinary course of its businesses, including claims for:

• (a) Overtime—Lawsuits claiming the payment of overtime, for time allegedly worked after regular working hours.
• (b) Salary differences and related effects—Substantially represents amounts arising from salary equalization/reclassification differences, claimed by employees who allegedly receive a lower compensation than coworkers holding a similar position, associated with other requirements provided for by the applicable law.
• (c) Hazardous work conditions—Reflect, substantially, the expected unfavorable outcome in lawsuits on the mandatory payment of hazardous duty premium to employees working under conditions classified as hazardous, mainly next to high-voltage installations.
• (d) Indemnities—Refer to reimbursement of or compensation claims for damages suffered while employed by the company, for several reasons, such as: occupational accidents, temporary tenure, pain and suffering, reimbursement of payroll deductions, daycare allowance, and productivity bonuses according to collective bargaining agreements.
• (e) Stability and integration—Claim due to alleged non-compliance with an employee's special condition which prohibited termination of the employment contract without cause.
• (f) Additional post retirement benefits—Claims related to differences allegedly due in the pension benefit of former employees, proportionally to other claimed amounts granted by courts and not initially considered in the calculation of the pension benefit.
• (g) Lawyers and expert fees—Installments paid to the plaintiffs' lawyers and appointed court experts, when expert evidence is necessary during the fact-finding stage.
• (h) Contractual rescissions—Amounts due to claimants arising from the termination of employment contract, such as vacation pay (proportional/vested), thirteenth salary FGTS fine, and the increase in this pay proportionally to other amounts claimed that allegedly should be included in the calculation of severance pay.
• (i) Other labor contingencies—Include primarily joint liability allegations by employees of thirdparty service providers, lawsuits related to differences owed on the deposits in the claimant's severance pay fund (''FGTS'') and labor fines arising from delays or non-payment of certain amounts provided for by the employment contract.

As at 31 December 2011, the total estimated contingencies in connection with labor claims against Oi and Contax in respect of which the risk of loss was deemed probable totaled R\$1,980 million, as compared to R\$2,079 million as at 31 March 2011.

49. Litigation (Continued)

(iii) Tax contingencies

(a) ICMS (Value Added Tax)

Under the regulations governing the ICMS, in effect in all Brazilian states, telecommunications companies must pay ICMS on every transaction involving the sale of telecommunication services they provide. Oi may record ICMS credits for each of its purchases of operational assets. The ICMS regulations allow Oi to apply the credits it has recorded for the purchase of operational assets to reduce the ICMS amounts it must pay when it sells its services.

Oi has received various tax assessments challenging the amount of tax credits that it recorded to offset the ICMS amounts it owed. Most of the tax assessments are based on two main issues: (1) whether ICMS is due on those services subject to the Local Service Tax (Imposto Sobre Servi¸cos de Qualquer Natureza), or ISS; and (2) whether some of the assets it has purchased relate to the telecommunication services provided, and, therefore, qualify for an ICMS tax credit. A small part of the assessments that are considered to have a probable risk of loss relate to: (1) whether certain revenues are subject to ICMS tax or ISS tax; (2) offset and usage of tax credits on the purchase of goods and other materials, including those necessary to maintain the network; and (3) assessments related to non-compliance with certain ancillary (non-monetary) obligations.

As at 31 December 2011, Oi recorded provisions in the amount of R\$605 million for those assessments in respect of which it deemed the risk of loss as probable, as compared to R\$624 million as at 31 March 2011.

(b) FUNTTEL

FUNTTEL (Fundo para o Desenvolvimento Tecnologico das Telecomunica¸ ´ coes) is a fund that was ˜ established to finance telecommunications technology research, for which Oi is required to make contributions. Due to a change by ANATEL in the basis for calculation of its contributions to the FUNTTEL, for which Oi has questioned its legality, Oi recorded provisions for additional contributions to these funds. As at 31 December 2011, Oi recorded provisions in the amount of R\$121 million for assessments of the FUNTTEL, as compared to R\$111 million as at 31 March 2011.

49. Litigation (Continued)

b) Possible loss

As at 31 December 2011 and 31 March 2011, the nature of the legal proceedings and tax contingencies against Oi and Contax for which the risk of loss was deemed possible is as follows:

		31 Dec 2011	31 Mar 2011
	Euro (proportional)	Brazilian Reais (100%)	Euro (proportional)	Brazilian Reais (100%)
	Million
Civil(i)	140.2	1,297.1	162.0	1,439.6
Labor(ii)	256.6	1,930.7	420.9	3,392.4
Tax(iii)	1,949.0	18,325.5	1,849.6	16,618.5
Total (Note 49.1)	2,345.8	21,553.3	2,432.5	21,450.5

(i) Civil contingencies

Refer to lawsuits for which no court decision has been issued, and are mainly related, but not limited to, challenging of network expansion plans, compensation for pain and suffering and material damages, collection lawsuits, bidding processes, among other. The total amount included in the table above regarding civil contingencies is based exclusively on the amounts claimed by the plaintiffs, which are typically higher than the actual claim case.

The challenges described above also include certain ongoing litigation with committed subscribers and assignees of committed subscribers of fixed telephony in Region I, who alleged non-full compliance with certain financial participation agreements prior to the privatization. These lawsuits currently involve approximately 50 thousand agreements and Oi did not recognize any provision since its legal counsel assesses the risk of loss as possible. As the lawsuits related to these agreements were not yet trialed it is not practicable to measure possible disbursements in such lawsuits. Accordingly, based on the provisions of IAS 37, Oi does not have an estimate of the amounts involved to be disclosed in is financial statements.

In September 2004, the Federal Public Prosecution Office and the Rio de Janeiro State Public Prosecution Office filed a civil suit against TNL, Telemar, TNL PCS and the Federal Government requesting the annulment of the transfer of the TNL PCS share control to Telemar, and the payment of compensation for pain and suffering and material damages allegedly inflicted to the non-controlling shareholders and the financial market. The sale of TNL PCS share control to Telemar is also challenged by two non-controlling shareholders and by the CVM in an administrative proceeding filed to determine whether there were any irregularities in the transaction. Oi deemed the risk of loss of those two claims as possible. These three claims were judged unfounded by the lower court and accordingly Oi's legal counsel reassessed the possibility of loss from possible to remote.

Portugal Telecom, SGPS, S.A. Notes to the Consolidated Financial Statements (Continued) As at 31 December 2011

(Amounts expressed in Euros, except where otherwise stated)

49. Litigation (Continued)

In July 2009, a class civil action was filed against Telemar by the Federal Government, the Federal Public Prosecution Office, the Federal District and Territories Public Prosecution Office, customer protection bodies and several State Consumer Protection Agencies seeking compensation for alleged collective pain and suffering caused by non-compliance of the rules to establish general Customer Service standards. Telemar filed its defense arguments on 16 September 2009, and waits the lower court decision.

Telemar and its subsidiaries are subject to administrative proceedings and preliminary investigations conducted by the Brazilian antitrust authorities with respect to potential violations of the Brazilian antitrust law. Such investigations may result in penalties, including fines. To date, no fines or penalties have been levied against Telemar and its subsidiaries. Oi deemed the risk of loss as possible that it will be fined in one or more of such proceedings and have not recorded any provisions for those claims

(ii) Labor contingencies

Refer to several lawsuits claiming, but not limited to, the payment of salary differences, overtime, hazardous duty premium, and joint liability, the nature of which is described in detail above.

(iii) Tax contingencies

As at 31 December 2011, the estimated contingencies in connection with tax proceedings against Oi and Contax in respect of which the risk of loss was deemed possible amounted to R\$18,276 million, as compared to R\$16,618 million as at 31 March 2011. The Brazilian corporate tax system is complex, and Oi and Contax are currently involved in tax proceedings regarding certain taxes that the companies believe are unconstitutional, and have filed claims to avoid the related payment. These tax contingencies relate primarily to the following.

• (a) Value Added Tax (''ICMS'')—Tax assessments amounting approximately to R\$5,646 million, which relate mainly to (1) ICMS levied on certain revenue from services already subject to ISS or which are not part of the ICMS tax base, and (2) utilization of ICMS credits on the purchase of goods and other inputs necessary for network maintenance;
• (b) City taxes—Tax assessments related to taxes levied by City authorities, including mainly the taxes levied on equipment leases, wakeup call services, and other communication services. The total amount involved is approximately R\$2,487 million, which is not accrued because the legal counsel in charge considers the likelihood of an unfavorable outcome possible since these activities do not qualify under the ISS service list or are already subject to ICMS. Also, in the last quarter of 2001, the STF decided, thus strengthening the defense arguments, that ISS should not be levied on the lease of equipment, where a substantial portion of the assessed tax refers to this type of revenue.

49. Litigation (Continued)

• (c) INSS—Lawsuits amounting approximately to R\$1,590 million, mainly related to joint liability, applicable percentage of Occupational Accident Insurance (SAT), and amounts subject to social security contribution.
• (d) Federal taxes—Federal tax assessments, mainly related to alleged undue offset and self-assessments of taxes due, and disallowing previous calculations, amounting approximately to R\$6,085 million.

50. Subsequent events

Following the revision of the sovereign rating to BB, Standard & Poors, on 21 January 2012, reviewed the credit rating attributed to Portugal Telecom, downgrading the long-term rating from BBBto BB+, with negative outlook, and the short-term rating from A-3 to B. On 13 April 2012, Moody's announced its review of the credit ratings of Portugal Telecom and its wholly owned subsidiary PT Finance, through which Portugal Telecom have obtained certain of its indebtedness, downgrading the long-term ratings from Ba1 to Ba2, with negative outlook.

At the Board of Directors meeting of Brasil Telecom held on 6 February 2012, it was approved the issuance of non-convertible debentures amounting to R\$ 2,000 million.

In February 2012, Brasil Telecom issued Senior Notes amounting to US\$ 1,500 million, which mature in February 2022 and bear interest at an annual rate of 5.75%.

The general meetings of Brasil Telecom, TNL, Coari and Telemar, held on 27 February 2012, approved Oi's corporate simplification (Note 1). Following this approval, the current corporate structure constituted by TNL, Telemar and Brasil Telecom is integrated in Brasil Telecom, which will be renamed Oi S.A., and will have only two share classes (common shares, ON, and preferred shares, PN) traded in the Bovespa and in the NYSE, through an ADR programme. As a result of this approval, the new Oi S.A. will issue 395,585,453 new ordinary shares and 798,480,405 preferred shares and its subscribed capital, fully paid, will be R\$ 6,816,467,847.01, divided into 599,008,629 common shares and 1,198,077,775 preferred shares, all nominative and without par value. The number of shares outstanding and therefore the final position of Telemar Participa¸coes, Oi's controlling shareholder, and Portugal ˜ Telecom will be established after the exercise of withdrawal rights by shareholders entitled to such. Portugal Telecom's estimated economic position in Oi, direct and indirect, will be between 21.5% and 25.1%. The period of application of the withdrawal ends on 29 March 2012.

Except for those mentioned above, there were no significant events occurred after 31 December 2011 either requiring adjustment or disclosure in these consolidated financial statements.
