The decreases mentioned above were partially offset by the 3.1% tariff adjustment since December 2013.

5.1. Payroll and benefits

In 2Q14 payroll and benefits grew R$ 59.4 million or 12.1%, from R$ 492.0 million to R$ 551.4 million, due to the following:

· R$ 17.9 million increase in provisions, from the higher number of employees who are entitled to request retirement (TAC), in addition to the wage increase in the period;

· R$ 14.0 million increase due to the 8.0% increase in wages since May 2013 and the average wage increase of 6.80% since May 2014, in addition to the changes from the career and wage plan carried out by the Company;

· R$ 8.0 million upturn in the provision for the Pension Plan, arising from changes in actuarial assumptions;

· R$ 4.4 million increase in expenses related to the Profit Sharing Program, chiefly due to lower reversal of provision occurred in 2Q14, due to higher compliance with the targets estimated for the period, combined with adjustments made in the period; and

· R$ 4.3 million increase in overtime pay, mainly due to wage adjustment in the period, and the higher number of hours exercised.

5.2. Supplies

In 2Q14, expenses with supplies decreased R$ 2.5 million or 5.1%, when compared to the same period of the previous year, from R$ 49.4 million to R$ 46.9 million, mostly due to:

· R$ 1.2 million decrease, basically due to space that has been adapted to develop Sabesp Information Integrated System (SiiS), in 2Q13; and

· Lower use of materials in preventive and corrective maintenance and in several water and sewage systems, thus, resulting in a reduction of R$ 0.8 million.

5.6. General expenses

General expenses grew R$ 3.7 million or 2.0%, totaling R$ 190.0 million, versus the R$ 186.3 million recorded in 2Q13, due to the following:

7.1.1. Financial expenses

Financial expenses grew R$ 55.7 million or 60.2%. The main reasons were:

· R$ 39.7 million increase in other financial expenses, chiefly due to the favorable results of lawsuits in 2Q13, reducing interest expenses in that period, representing a variation of R$ 37.8 million; and

· R$ 15.0 million increase in interest and charges on domestic loans and financing, due to the higher increase in the Interbank Deposit Certificate (CDI) in 2Q14 (10.8%), versus 2Q13 (7.7%).

7.1.2. Financial revenues

Financial revenues from interests dropped R$ 7.2 million or 8.9%, due to lower number of instalment agreements held in 2Q14.

7.2.1. Monetary/exchange rate variation on liabilities

The effect on the monetary/currency exchange variation on liabilities in 2Q14 was R$ 258.1 million, lower than in 2Q13, especially due to:

· Revenue of exchange rate variation in the amount of R$ 84.2 million in 2Q14, mainly deriving from the depreciation of the US Dollar and Japanese Yen versus Brazilian Real (2.7% and 1.0%, respectively), versus an expense of exchange rate variation of R$ 201.7 million in 2Q13, deriving from the appreciation of both currencies (10.0% and 4.3%, respectively);

· R$ 12.5 million increase in monetary variation expenses over domestic loans and financing, mainly due to the higher variation of the IPCA rate in 2Q14 (2.06%), versus a 1.4% variation recorded in 2Q13. This increase is also a result of the higher amount of debt indexed to the IPCA rate, due to the 18 th debenture issuance, in December 2013; and

· R$ 15.2 million increase in other monetary variation due to the greater need of provision for lawsuits, in the amount of R$12.6 million.

1 Operations

Companhia de Saneamento Básico do Estado de São Paulo ("SABESP" or the "Company") is a mixed-capital company headquartered in São Paulo, at Rua Costa Carvalho, 300, CEP 05429-900, controlled by the São Paulo State Government. The Company is engaged in the provision of basic and environmental sanitation services in the State of São Paulo, as well as it supplies treated water on a wholesale basis .

In addition to providing basic sanitation services in the State of São Paulo, SABESP may perform these activities in other states and countries, and can operate in drainage, urban cleaning, solid waste handling and energy markets. The objective set in the new vision of SABESP is to be recognized as the company that ensured universal access to water and sewage services in its marketplace , in a sustainable and competitive manner, with excellence in customer service.

On June 30, 2014, the Company operated water and sewage services in 364 municipalities of the State of São Paulo. Most of these municipalities operations are based on 30-year concession, program and services contracts. The Company has two partial contracts with the municipality of Mogi das Cruzes, however, since most of municipality is serviced by wholesale, it was not included in the 364 municipalities. On June 30, 2014, the Company had 366 contracts.

SABESP is not temporarily operating in some municipalities due to judicial orders. The lawsuits in progress refer to Álvares Florense, Cajobi, Embaúba, Iperó and Macatuba, and the carrying amount of these municipalities' intangible assets was R$11,330 as of June 30, 2014 .

As of June 30, 2014 , 54 concession agreements had expired and are being negotiated . From 2014 to 2030, 38 concession agreements will expire . Management believes that concession agreements expired and not yet renewed will result in new contracts, disregarding the risk of discontinuity in the provision of municipal water supply and sewage services . By June 30, 2014 , 274 program and services contracts were signed (266 contracts on December 31, 2013).

As of June 30, 2014 , the carrying amount of the underlying assets used in the 54 concessions of the municipalities under negotiation totaled R$6,012,934, accounting for 24.40% of total, and the related gross revenue for the six-month period then ended totaled R$951,526 on June 30, 2014 , accounting for 16.19% of total.

The Company's operations are concentrated in the municipality of São Paulo, which represents 49.79% of the gross revenues on June 30, 2014 (51.15% on June 30, 2013) and 41.62% of intangible assets (42.46% on December 31, 2013).

On June 23, 2010, the State of São Paulo, the municipality of São Paulo, the Company and the regulatory agency “Sanitation and Energy Regulatory Agency – ARSESP” signed an agreement to share the responsibility for water supply and sewage services to the Municipality of São Paulo based on a 30-year concession agreement. This agreement is extendable for another 30 years, pursuant to the law. This agreement sets forth SABESP as the exclusive service provider and designates ARSESP as regulator, establishing prices, controlling and monitoring services .

Also, on June 23, 2010, the State of São Paulo, the city of São Paulo and SABESP signed the “Public service provision agreement of water supply and sewage services”, a 30-year concession agreement which is extendable for another 30 years. This agreement involves the following activities :

i. protection of the sources of water in collaboration with other agencies of the State and the City ;

ii. capture, transport and treat of water ;

iii. collect, transport, treatment and final dispose of sanitary sewage; and

iv. adoption of other actions of basic and environmental sanitation .

In the municipality of Santos, in the Santos coast region, which has a significant population, the Company operates under an authorization by public deed, a situation similar to other municipalities in that region and in the Ribeira valley, where the Company started to operate after the merger of the companies that formed it . As of June 30, 2014, the carrying amount of the municipality of Santos’ intangible assets was R$307,275 (R$340,530 on December 31, 2013) and gross revenue in the six-month period ended June 30, 2014 was R$117,885 (R$124,077 on June 30, 2013).

Article 58 of Law 11,445/07 determines that precarious and overdue concessions, as well as those effective for an undetermined period of time, including those that do not have an instrument formalizing them, will be valid until December 31, 2010. However, Article 2 of Law 12,693 of July 24, 2012 allows program agreements to be executed until December 31, 2016.

The Company’s Management understands that the concession agreements not yet renewed are valid and will be governed by Laws 8,987/95 and 11,445/07, including those municipalities served without an agreement.

Public deeds are valid and governed by the Brazilian Civil Code.

The Company's shares have been listed in the Novo Mercado (New Market) segment of BM&FBovespa under the ticker symbol SBSP3 since April 2002 and on the New York Stock Exchange (NYSE) as American Depositary Receipts (“ADRs”) Level III, under the SBS code, since May 2002 . In 2007, SABESP adhered to the Corporate Sustainability Index, or ISE of BM&FBovespa, which reflects the high level of commitment with sustainable development and social practices.

Since 2008, the Company has been setting up partnerships with other companies, which resulted in the following companies: Sesamm, Águas de Andradina, Saneaqua Mairinque, Aquapolo Ambiental, Águas de Castilho and Attend Ambiental. Although SABESP has no majority interest in the capital stock of these companies, the shareholders’ agreements provide for the power of veto and casting vote in certain issues jointly with associates, indicating the shared control in the management of investees.

The interim financial information was approved by the Board of Directors on August 14, 2014 .

3 Financial Risk Management

3.1 Financial risk factors

The Company's activities are affected by Brazilian economic scenario , making it exposed to market risk, such as exchange rate, interest rate, credit risk and liquidity risk.

ITR –– Quarterly Information Form – June 30, 2014 – CIA SANEAMENTO BÁSICO ESTADO SÃO PAULO Notes to the Interim Financial Information Version: 1

(a) Market risk

Foreign currency risk

SABESP’s foreign exchange exposure implies market risks associated with Brazilian Real currency fluctuations against the US dollar and yen. SABESP’s foreign currency-denominated liabilities mainly include US dollar and yen-denominated loans .

In case of Brazilian real depreciation in relation to foreign currency in which the debt is denominated, SABESP will incur in monetary loss in relation to such debt .

SABESP’s specific foreign currency risks are related to exposures caused by its current and non-current debts denominated in foreign currency .

The management of SABESP’s foreign currency exposure considers several current and projected economic factors, besides market conditions .

This risk arises from the possibility that the Company may incur in losses due to exchange rate fluctuations that would impact liability balances of foreign currency-denominated loans and financing raised in the market and related financial expenses. The Company does not maintain hedge or swap contracts or any financial instrument to hedge against this risk, but conducts an active management of debt, taking advantage of opportunities to change expensive debts with “cheaper” debts, reducing the cost through early maturity.

A significant amount of the Company’s financial debt is indexed to the U.S. dollar and Yen, in the total amount of R$3,611,392 on June 30, 2014 (R$3,715,645 in December 2013). Below, the Company’s exposure to foreign exchange risk :

June 30,2014 — Foreign currency R$ December 31, 2013 — Foreign currency R$
Loans and financing – US$ 1,197,399 2,637,271 1,181,256 2,767,210
Loans and financing – Yen 43,800,424 952,659 41,504,249 926,790
Interest and charges from loans and financing – US$ 14,592 14,512
Interest and charges from loans and financing – Yen 6,870 7,133
Total exposure 3,611,392 3,715,645
Financing cost (17,735) (17,092)
Total loans in foreign currency 3,593,657 3,698,553

As of June 30, 2014, if the Brazilian rea l had depreciated or appreciated by 10% against the US dollar and Yen with all other variables held constant, effects on results before taxes on June 30, 2014 would have been R$361,139 (R$371,564 in December 2013), lower or higher, mainly as a result of foreign exchange losses or gains on the translation of foreign currency-denominated loans.

(*) The probable scenario in foreign currency (US dollar and Yen) considered the average exchange rate for the 12-month period after June 30, 2014, according to BM&FBovespa.

Interest rate risk

This risk arises from the possibility that the Company could incur losses due to fluctuations in interest rates, increasing the financial expenses related to loans and financing.

The Company has not entered into any derivative contract to hedge against this risk; however continually monitors market interest rates, in order to evaluate the possible need to replace its debt .

The table below provides the Company's loans and financing subject to variable interest rate :

(v) LIBOR - London Interbank Offered Rate

Another risk to which the Company is exposed, is the mismatch of the monetary restatement indices of its debts with those of its service revenues. Water supply and sewage services tariff adjustments do not necessarily follow the increases in the inflation indexes to adjust loans, financing and interest rates affecting the Company's indebtedness .

On June 30, 2014, if interest rates on loans and financing denominated in Brazilian reais had been 100 basis points higher or lower with all other variables held constant, the effects on profit for the six-month period ended June 30, 2014, before taxes would have been R$73,501 (R$69,831 in December 2013) lower or higher, mainly as a result of a lower or higher interest expense on floating rate loans and financing.

(b) Credit risk

Credit risk arises from cash and cash equivalents, deposits in banks and financial institutions, as well as credit exposures to wholesale basis and retail customers, including outstanding accounts receivable, restricted cash, accounts receivable from related parties and indemnities. Credit risk exposure is mitigated by sales to a dispersed customer base.

The maximum exposures to credit risk at the reporting date are the carrying amounts of instruments classified as cash equivalents, deposits in banks and financial institutions, restricted cash, trade accounts receivable and accounts receivable from related parties in the balance sheet date , as per Notes 5, 6, 7 and 8.

Regarding the financial assets held with financial institutions, the credit quality that is not past due or subject to provision for impairment may can be assessed by reference to external credit ratings (if available) or to historical information about counterparty default rates. The credit quality of counterparties which are banks, such as deposits and financial investments, the Company considers the lower rating of the counterparty published by three main international rating agencies (Moody's, Fitch and S&P), according to internal policy of market risk management :

(ii) Debentures were projected up to the final maturity date according to contractual rates (IPCA, DI, TJLP or TR), and discounted to present value considering the future interest rate published by ANBIMA in the secondary market, or by market equivalent rates, or the Company’s share traded in the Brazilian market.

(iii) BNDES loans are financial instruments valued at carrying amount plus contractual interest rate till mature date, and are indexed by long term interest rate – TJLP .

*(CONVENIENCE TRANSLATION INTO ENGLISH FROM THE ORIGINAL PREVIOUSLY ISSUED IN PORTUGUESE)*

ITR –– Quarterly Information Form – June 30, 2014 – CIA SANEAMENTO BÁSICO ESTADO SÃO PAULO Notes to the Interim Financial Information Version: 1

These loans have specific characteristics and the conditions defined in the loan agreements with BNDES between independent parties, and reflect the conditions for those types of loan. In Brazil, a consolidated market of long-term debts does not exist with the same characteristics of BNDES loans, the offering of credit to the entities in general, with this long-term characteristic, usually is restricted to BNDES.

(iv) Other financing in local currency are considered by carrying amount plus contractual interest rate till mature date, discounted to present value considering a future interest rate published by BM&FBovespa.

(v) Agreements with IDB, IBRD, were projected until final maturity in origin currency, applying interest rates contracted, discounted at present value at Libor futures rate, obtained from Bloomberg. Eurobonds were priced at market value through quotes published by Bloomberg. All the amounts obtained were translated into Brazilian reais at the exchange rate of June 30, 2014.

(vi) Agreements with JICA, were projected until final maturity in origin currency, using interest rates contracted and discounted at present value, at Tibor futures rate obtained from Bloomberg. The amounts obtained were translated into Brazilian reais at the exchange rate of June 30, 2014.

(vii) Leases are financial instruments considered by face value restated until maturity date, whose characteristic is the indexation by fixed contractual rate, which is a specific type, not compared to any other market rate. Thus, the Company discloses as market capitalization, the amount recorded on June 30, 2014.

Considering the nature of other financial instruments, assets and liabilities of the Company, the balances recognized in the statement of financial position approximate the fair values, taking into account the maturities close to the end of the reporting period, comparison of contractual interest rates with market rates in similar operations at the end of the reporting periods, their nature and maturity terms .

4 Critical accounting estimates and judgments

(c) U se of reservoirs - EMAE

Empresa Metropolitana de Águas e Energia S.A. - EMAE plans to receive for the credit and to obtain financial compensation for the use of water from the Guarapiranga and Billings reservoirs, which SABESP uses in its operations, as well as the reimbursement of damages related to the failure to pay appropriately.

The Company understands that no amounts are due for the use of these reservoirs given the grants already made . Should these reservoirs not be available for use to the Company, there could be the need to collect water in more distant places. There is a risk of not properly rendering services in the region, besides increasing water supply cost.

Several lawsuits were filed by EMAE, among them a lawsuit to create an arbitration clause related to the Guarapiranga reservoir, a proceeding which had already started and another one, equally pleading for financial compensation due to SABESP’s water collect from Billings reservoir for public supply, these two lawsuits alleging that this conduct has been causing permanent and growing loss in the capacity of generating electricity of Henry Borden hydroelectric power plant with financial losses.

(i) Customer claims

Approximately 1,300 lawsuits were filed by commercial customers, which claim that their tariffs should correspond to other consumer categories, and 720 lawsuits which claim a reduction in the sewage tariff due to losses in the system, consequently requesting the refund of amounts charged by the Company. The Company was granted both favorable and unfavorable final decisions at several court levels and recognized provisions when the chances of losses are probable. The R$31,687 increase in the lawsuits classified as probable loss (net of escrow deposits) is related to new lawsuits filed and interest rates, fees and updates of lawsuits in progress, partially offset by payments made in the year and revisions of expectations caused by favorable decisions during 2014.

(ii) Supplier claims

Suppliers’ claims include lawsuits filed by some suppliers alleging underpayment of monetary restatements, withholding of amounts related to the understated inflation rates deriving from Real economic plan, and the economic and financial imbalance of the agreements. These lawsuits are in progress at different courts and a provision is recognized when the chances of losses are probable. The R$83,606 decrease in lawsuits whose likelihood of loss is considered probable (net of escrow deposits) is mainly related payments made during 2014.

(iii) Other civil claims

These mainly refer to indemnities for property damage, pain and suffering, and loss of profits allegedly caused to third parties, filed at different court levels, dully accrued when classified as probable losses. The R$17,172 decrease in lawsuits with probable chances of loss (net of escrow deposits) was mainly due to shelving of several lawsuits and revisions of expectations caused by favorable decisions to the Company during 2014.

(iv) Tax claims

Tax claims refers mainly to issues related to tax collections challenged due to differences in the interpretation of legislation by the Company's management, accrued when classified as probable loss.

(v) Labor claims

The Company is a party to labor lawsuits, involving issues such as overtime, shift schedule, health hazard premium and hazardous duty premium, prior notice, change of function, salary equalization, and other. Part of the amount involved is in provisional or final execution at various court levels, and thus is classified as of probable or possible loss. The Company recognized a provision for claims which likelihood of loss is considered probable. The R$11,854 increase in lawsuits with probable chances of losses (net of escrow deposits) is related to new lawsuits filed and interest rates, fees and updates of lawsuits in progress.

The amounts accrued represent the best estimate of the Company at this moment, however, may differ from the amount to be disbursed as indemnity to alleged damages, in view of the current stage of referred proceedings. The R$33,536 increase in lawsuits with expectation of probable losses (net of escrow deposits) is mainly related to the complementary estimates of lawsuits, agreements in progress and new lawsuits filed during the period of 2014 .

23 Operating Revenue

(a) Revenue from water and sewage services:

April to June 2014 January to June 2014 April to June 2013 January to June 2013
Metropolitan region of São Paulo 1,579,335 3,308,583 1,701,779 3,389,795
Regional Systems (i) 644,682 1,359,865 605,649 1,236,480
Total (ii) 2,224,017 4,668,448 2,307,428 4,626,275

(i) Including the municipalities operated in countryside and at the coast of the State of São Paulo.

(ii) Revenue from water and sewage services decreased by 3.6% in the second quarter of 2014 year-on-year. This result was mainly impacted by the incentive program for reduction of consumption (Bonus*).

  • Bonus: SABESP’s Incentive Program for Reduction of Water Consumption

After ARSESP’s approval on an emergency basis by means of Resolution 469/2014, SABESP adopted an economic incentive to encourage the population of Greater São Paulo to reduce water consumption. This measure was adopted due to the record heat and the unheard lack of rainfall at the Cantareira System, which is at a critical level and supplies almost 10 million people.

Consumers who reduce by, at least, 20% the average consumption of the twelve-month period, between February 2013 and January 2014, will receive 30% discount in their bills. The discount shall apply to a smaller amount, since reduced consumption will result in cheaper bills.

This measure applies to households, commerce and industries supplied by the Cantareira System – the entire north zone and São Paulo downtown, part of the east and west zones of São Paulo, Barueri, Caieiras, Carapicuíba, Francisco Morato, Franco da Rocha, Itapevi, Jandira, Osasco and Santana de Parnaíba. In Guarulhos and São Caetano do Sul, also supplied by the Cantareira System, distribution relies on the local governments, which buy water from SABESP. The municipal services shall resolve on granting this incentive.

The benefit will be valid for the bills of reference months from February to August, and consumers will receive the bills between March and September. In Santana de Parnaíba, this measure will be applied in the reference months from March to August and consumers will receive the bills between April and September.

However, in April 2014, the incentive program for reduction of water consumption was postponed until the end of 2014 to the entire São Paulo metropolitan region, or until water levels at reservoirs are regularized. Due to the dry weather and the low water volume at the Cantareira System, the Department of Water and Electricity of the State of São Paulo (DAEE) and the National Water Agency (ANA) set forth that, as of March 10, 2014, we are temporarily required to restrict the water outflow caught from the Cantareira System, from 33m 3 /s to 27.9m 3 /s. In order to supply this lower water availability and continue supplying the population, we are expanding the use of water from other water mains. This may increase costs to serve consumers of the metropolitan region of São Paulo. If the situation of the reservoirs affected by dry weather does not improve, we may be forced to take more drastic measures.

On May 26, 2014, the Incentive Program for Reduction of Water Consumption was expanded to the municipalities operated by SABESP which compose by Piracicaba basins, Capivari and Jaguari rivers, located in the coverage area of the Cantareira System.

Likewise, consumers who reduce by, at least, 20% their monthly consumption will be entitled to bonus, compared to the average consumption of the twelve-month period, between February 2013 and January 2014. These consumers will receive 30% discount on their water and sewage bills. The participating municipalities are Bragança Paulista, Joanópolis, Nazaré Paulista, Pinhalzinho, Piracaia, Vargem, Hortolândia, Itatiba, Jarinu, Monte Mor, Morungaba and Paulínia.

This measure includes residential, commercial, industrial and government customers and will be valid for the bills issued as of June 2014, effective until December 2014.

The amount of the discount for the first and second quarters of 2014 was R$10,778 and R$88,084, respectively.

(i) There was no significant variation in the second quarter 2014 when compared to the same period.

(ii) The account variation mainly derives from an increase in debt balance indexed to IPCA in view of the 18 th Issue of Debentures. This inflation adjustment derives from changes in the indexes defined in loan agreements, such as, UPR, IPCA, CDI and TJLP, corresponding to 0.2%, 1.5%, 10.8% and 1.3%, respectively, in the second quarter of 2014. (0.0%, 1.2%, 7.7% and 1.3%, respectively, in the same period of 2013). The exposures to these rates are shown in Note 3.1.

(iii) This reduction derives from the variation in the National Consumer Price Index (INPC) rate of 1.6% in the second quarter of 2014 and 1.2% in the same period of 2013, which is used to adjust the balance of SABESP’s commitment in relation to the deficit of the Sabesprev Mais pension plan.

(iv) Other expenses related to inflation adjustment mainly arises from the adjustment of liabilities referring to investment commitments required by the public-private partnerships and mainly from program contracts indexed by the IPC and IPCA of 0.8% and 1.5% in the second quarter of 2014 and 0.7% and 1.2% % in the second quarter of 2013, respectively.

(v) These inflation adjustments arise from accounts/bills of overdue accounts receivable, which are remesured depending on the payment date, by IPCA (1.5% in the second quarter of 2014 and 1.2% in the same period of 2013) or IPC-FIPE (Consumer Price Index, 0.8% in the second quarter of 2014 and 0.7% in the same period of 2013), and escrow deposits, which are adjusted by the index defined by the Judiciary Branch, which varied between 2.2% in the second quarter of 2014 and 1.5% in the same period of 2013. Such decrease was mainly due to reversal of monetary restatement on escrow deposits, the change in the expected return thereof.

(vi) The variation is mainly due to the reduced interest rates on agreements and installment payments in the second quarter of 2014.

REPORT ON REVIEW OF INTERIM FINANCIAL INFORMATION

To the Shareholders, Board of Directors and Management of

Companhia de Saneamento Básico do Estado de São Paulo - SABESP

São Paulo - SP

Introduction

We have reviewed the accompanying interim financial information of Companhia de Saneamento Básico do Estado de São Paulo - SABESP (the “Company”) included in the Interim Financial Information Form (ITR), for the quarter ended June 30, 2014, which comprises the balance sheet as of June 30, 2014 and the related statements of income and comprehensive income for the three and six-months period then ended and changes in equity and of cash flows for the six-month period then ended, including the explanatory notes.

The Company’s Management is responsible for the preparation of the interim financial information in accordance with technical pronouncement CPC 21 (R1) - Interim Financial Information and with international standard IAS 34 - Interim Financial Reporting, issued by the International Accounting Standards Board - IASB, as well as for the presentation of such information in accordance with the standards issued by the Brazilian Securities and Exchange Commission (CVM), applicable to the preparation of Interim Financial Information (ITR). Our responsibility is to express a conclusion on this interim financial information based on our review.

Scope of review

We conducted our review in accordance with Brazilian and international standards on review of interim financial information (NBC TR 2410 and ISRE 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity, respectively). A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with standards on auditing and, consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion on the interim financial information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying interim financial information included in the ITR referred to above was not prepared, in all material respects, in accordance with technical pronouncement CPC 21 (R1) and international standard IAS 34, applicable to the preparation of Interim Financial Information (ITR), and presented in accordance with the standards issued by the CVM.

Other matters

Statements of value added

We have also reviewed the statements of value added (DVA) for the six-month period ended June 30, 2014, prepared under the responsibility of the Company’s Management, the presentation of which is required by the standards issued by the CVM applicable to the preparation of Interim Financial Information (ITR) and considered as supplemental information for International Financial Reporting Standards - IFRS, which does not require the presentation of DVA. These statements were subject to the same review procedures described above, and, based on our review, nothing has come to our attention that causes us to believe that they were not prepared, in all material respects, consistently with the interim financial information taken as a whole.

The accompanying interim financial information has been translated into English for the convenience of readers outside Brazil.
