In 2Q12, net operating revenue reached R$ 2.5 billion, a 5.8% growth compared to 2Q11. Costs and expenses, including construction costs, in the amount of R$ 1.9 billion grew 6.5% over 2Q11. EBIT grew 3.7%, from R$ 599.3 million in 2Q11 to R$ 621.4 million in 2Q12. EBITDA increased 3.0%, from R$ 775.5 million in 2Q11 to R$ 798.4 million in 2Q12. The EBITDA margin was 32.3% in 2Q12 in comparison to 33.1% in the same period of the previous year. Excluding construction revenues and construction costs, the EBITDA margin was 41.4% in 2Q12 (41.5% in 2Q11).

Comparing 2Q12 to 2Q11, the main variation was at the “Exchange rate variation on loans and financing”. This non cash effect was due to the depreciation of the Real versus US Dollar and Japanese Yen of 10.9% and 14.6%, respectively.

Excluding the effect from the exchange rate variation and its taxes, net income in 1H12 would have reached R$ 865.6 million (R$ 567.8 million in 1H11). 2Q12 net income would have reached R$ 478.7 million (R$ 430.6 million in 2Q11), corresponding to an 11.2% increase.

The EBITDA margin in 1H12 was 33.4% (30.8% in 2011). Excluding construction revenues and construction costs, the EBITDA margin was 42.4% (38.2% in 2011).

2. Gross operating revenue

Gross operating revenue from water supply and sewage collection grew from R$ 1,985.4 million in 2Q11 to R$ 2,048.6 million in 2Q12, an increase of R$ 63.2 million or 3.2%. The main factors for this result were: the increase of 1.4% in total billed volume, and the tariff adjustment of 6.83% as of September 2011.

The less-than-expected growth was due to: the conclusion of the implementation of TACE ( 1 ) services in municipalities in the interior region, which led to greater billing speed and reduced water bill reception times. There was also a decline in the number of days whose unbilled supply is estimated (revenue estimate). As a result, billing reflected the sales upturn and the tariff increase, but unbilled revenue estimates, which also comprise operating revenue, were lower than the estimates for previous periods.

Excluding this non-recurring event, operating revenue would have grown by 7.8%.

(1) TACE (External Commercial Service Technician) – allows the metering and issuing of water and sewage bills immediately at the client’s door. Consumers can ask questions more conveniently. The technician can also issue a copy of the bill, request repairs, provide water saving tips and make changes to the clients’ registration.

3. Construction revenue

In 2Q12, construction revenue grew from R$ 498.5 million to R$ 577.8 million, an increase of R$ 79.3 million or 15.9%, comparing to 2Q11. This variation was mainly due to higher investments in the period.

4. Billed volume

5.1. Payroll and benefits

In 2Q12 payroll and benefits grew R$ 31.5 million or 7.6%, from R$ 412.1 million to R$ 443.6 million, due to the following:

· 8% increase in wages since May 2011 and of 6.17% since May 2012, with an impact of approximately R$ 21.0 million; and

· Increase of R$ 11.4 million referring to actuarial liability of the G0 Plan.

5.2. Supplies

In 2Q12, expenses with supplies increased by R$ 8.6 million or 24.9%, when compared to the same period of the previous year, from R$ 34.6 million to R$ 43.2 million, mostly due to: (i) reincorporation to the stockroom of surplus material used in the maintenance of water and sewage connections and networks totaling R$ 3.6 million in 2Q11; and (ii) water and sewage systems preventive and correction maintenance, in the amount of R$ 2.2 million. Excluding the reincorporation to the stockroom of surplus material the variation would drop from 24.9% to 13.1%.

5.3. Treatment supplies

Treatment supplies expenses in 2Q12 were R$ 15.4 million or 42.8% higher than in 2Q11, from R$ 36.0 million to R$ 51.4 million. The main factors for this variation were:

· Increase of R$ 7.4 million, due to the higher consumption of activated carbon, due to the reservoir and climate conditions, as well as by the proliferation of algae in dams that serve the Guarapiranga and Cantareira production systems;

· Increase of R$ 3.3 million, due to the greater consumption of lime for the treatment of sludge and a price increase of approximately 23.8%;

· Increase of R$ 2.9 million from the greater consumption of hydrogen peroxide at the sewage pumping stations of the Baixada Santista Region due to the proliferation of algae, startup of the Guarujá sewage pumping station and a price increase of approximately 12.0%; and

· Increase of R$ 1.6 million due to the higher consumption of iron chloride, which replaces iron sulfate, due to the weather conditions.

Page 27 of 94

5.4. Services

In 2Q12 this item increased R$ 20.0 million or 8.6%, from R$ 232.6 million to R$ 252.6 million. The main factors were:

· Increase of R$ 11.9 million related to joint social and environmental initiatives established in the agreement entered into with the municipal government of São Paulo;

· Increase of R$ 6.4 million related to the fleet renewal program, though leasing ;

· Public and Private Partnership Agreement of the Alto Tietê Production System, with an increase of R$ 5.7 million due to the start-up in September 2011, increasing the water production capacity from 10m 3 /s to 15m 3 /s; and

· Paving services and replacement of sidewalks in the amount of R$ 5.0 million, due to the intensification of the actions against water losses.

The increases mentioned above were offset by a R$ 4.2 million decrease resulting from a lower achievement at the implementation of the Corporate Program for Water Loss Reduction (PURA) in municipal schools.

5.5. Electric power

In 2Q12, this item decreased R$ 3.7 million, or 2.4%, from R$ 151.3 million to R$ 147.6 million, due to a 15% discount granted, since September 2011, at the Use of Distribution System Tariff (TUSD), in the operation directly related to sanitation.

5.6. General expenses

In 2Q12 general expenses decreased R$ 33.3 million or 21.2%, from R$ 157.0 million to R$ 123.7 million, due to:

· Decrease in provision for legal contingencies, amounting to R$ 50.2 million;

· Increase of R$ 5.8 million in the provision for payment of the municipal fund pursuant to the Service Agreement with the Municipal Government of São Paulo; and

· Increase of R$ 2.1 million, due to the beginning of billing for the use of water from the Baixada Santista water basin in February 2012.

5.7. Credit write-offs

In 2Q12 credit write-offs decreased R$ 6.4 million or 14.9%, from R$ 43.0 million to R$ 36.6 million, mainly due to lower provisions of debits related to public entities.

6. Other operating revenues and expenses

Other operating revenues (net of expenses) decreased R$ 29.8 million, from R$ 46.9 million to R$ 17.1 million in 2Q12, due to the recognition of the funds received from the agreement of Alienation of Exclusivity Rights for deposits of Sabesp’s employees' payments from March 2007 and June 2011 with Nossa Caixa and Banco do Brasil, in the amount of R$ 36.3 million.

Financial expenses net of revenues	26.2	48.2	22.0	84.0

7.1. Financial expenses

In 2Q12 financial expenses dropped R$ 15.7 million, or 12.5%. The main factors that influenced this result were:

· Lower interest related to lawsuits against suppliers, in the amount of R$ 12.8 million;

· Decrease in interest by R$ 5.8 million on domestic loans and financing, mainly due to the amortization of the 8 th and 9 th debenture in June and October 2011, respectively; and

· Increase of R$ 7.8 million in interest from international loans and financing, due to the exchange rate variation.

7.2. Financial revenues

Financial revenues decreased by R$ 37.7 million, due to the gradual reduction of the market interest rates obtained in financial investments and higher cash position.

8. Monetary variation on assets and liabilities

	2Q11	2Q12	Var.	R$ million — %
Monetary variation on loans and financing	15.1	8.9	(6.2)	(41.1)

Net Variation	(71.8)	283.2	355.0	(494.4)

8.1. Monetary variation on liabilities

The effect on the monetary variation on liabilities in 2Q12 was R$ 344.2 million higher than in 2Q11, specially the exchange rate variation on international loans and financing, in the amount of R$ 356.0 million, due to the 10.9% appreciation of the US Dollar and of 14.6% appreciation of the yen in 2Q12 versus a 4.2% depreciation of the US Dollar and 1.12% depreciation of the yen in 2Q11.

Monetary variation on domestic loans and financing decreased by R$ 6.2 million, mainly due to the R$ 3.1 million decrease from the amortizations of the 8 th and 9 th debenture issues in June and October 2011 and the R$ 3.1 million decrease due to the lower variation of the TR interest rate in 2Q12 of 0.07%, compared with 0.31% in 2Q11.

Page 29 of 94

8.2. Monetary variation on assets

Monetary variation on assets dropped R$ 10.8 million, due to:

· Monetary restatement of judicial deposits in the amount of R$ 4.8 million in 2Q11; and

· R$ 7.6 million received in 2Q11 from the Sale of Exclusivity Rights for deposits of Sabesp’s employees' payments, which did not recur in 2Q12.

9. Operating indicators

Referring to the water loss ratio, in the first half of 2012, Sabesp invested R$122 million compared to R$132 million year on year. These amounts were sufficient to maintain the water loss ratio stable at 26%. With the beginning of the hiring financed by JICA, scheduled for mid-2013, a relevant fund transfer will occur, thus, a more substantial decline in this indicator is expected.

OPERATIONS

Companhia de Saneamento Básico do Estado de São Paulo ("SABESP" or the "Company") is a mixed-capital company headquartered in São Paulo, 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 supplying 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 ensures universal access to water and sewage services in its marketplace, focuses on the customer, in a sustainable and competitive manner, with excellence in environmental solutions.

On June 30, 2012, the company operated water and sewage services in 363 municipalities of the State of São Paulo, having temporarily discontinued operations in five of these municipalities, Araçoiaba da Serra, Iperó, Cajobi, Álvares Florense and Macatuba, due to judicial orders under ongoing lawsuits. Most of these municipalities operations are based on 30-year concession agreements. As at June 30, 2012, 94 concessions had expired and were being negotiated. From 2012 to 2033, 38 concessions will expire, and the remaining concessions operate on a rollover basis. These concessions with indefinite terms and expired concessions under negotiation are amortized over the useful lives of the underlying assets. By June 30, 2012, 231 contracts were signed (225 contracts on December 31, 2011).

Management believes that all concessions expired and not yet renewed will result in new contracts or contract extensions, disregarding the risk of discontinuity in the provision of municipal water supply and sewage services. On June 30, 2012, the carrying amount of intangible assets applied in 94 municipalities under negotiation totaled R$6,134 million, accounting for 29.4% of the total, and gross revenue from these municipalities totaled R$1,202 million, accounting for 22.35% of the total.

The Company’s operations are concentrated in the municipality of São Paulo, which accounted for 55.64% of gross revenue in June 2012 (December 2011 – 55.11%).

On June 23, 2010 the State of São Paulo through its Governor, the municipal government of São Paulo, represented by its mayor, SABESP and the Regulatory Agency of Sanitation and Energy– ARSESP as intervening and consenting parties entered into an agreement to share the responsibility for the water supply and sewage services in the capital city of São Paulo for the next 30 years, renewable for the same period. In addition, SABESP is the sole supplier of these services and ARSESP is liable for regulation, including tariffs, control and inspection of services.

Also, the “Water Supply and Sewage Public Utility Services Agreement” was signed on June 23, 2010. This agreement was signed between the State of São Paulo, the municipal government of São Paulo and SABESP for a 30-year period, renewable for the same period, including the following activities:

i. protection of springs in collaboration with other state and municipal authorities; ii. capture, transportation and treatment of raw water; iii. collection, transportation, treatment and final dispose of sanitary sewage; and iv. adoption of other basic and environmental sanitation actions.

Notes to the Financial Statements

In the municipality of Santos, in the Baixada Santista region, which has a significant population, the Company operates supported by a public authorization deed, a similar situation in other municipalities in that region and in the Ribeira valley, where the Company started to operate after the merger of the companies that it is made up of.

Concessions renewals occur based on Law 11,445, enacted on January 5, 2007, which establishes the basic sanitation regulatory framework, providing for the nationwide guidelines and basic principles for the provision of such services, such as social control, transparency, the integration of sanitation infrastructure, water resources management, and the articulation between industry policies and public policies for urban and regional development, housing, suppression of poverty, promotion of health and environmental protection, and other related issues.

The Company’s shares have been listed on the “Novo Mercado” (New Market) segment of the BOVESPA (São Paulo Stock Exchange) since April 2002, and on the New York Stock Exchange (NYSE) as ADRs since May 2002.

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. For the purposes of accounting classification in the financial statements, these companies are considered "joint ventures”, under the criteria of CPC 19.

These consolidated financial statements were approved by the Board of Directors on August 9, 2012.

FINANCIAL RISK MANAGEMENT

3.1 Financial risk factors

The Company’s operations are affected by the Brazilian economic scenario, especially foreign exchange variations, inflation and interest rates, exposing it to market risk, such as exchange rate, interest rate, credit risk and liquidity risk. The Company’s global risk management is focused on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Company’s financial performance.

The Company has not used derivative financial instruments, although it may contract forward foreign exchange operations and financing in Reais to reduce the foreign exchange risk.

(a) Market risk

Foreign Exchange Risk

SABESP's foreign exchange exposure implies market risks related to real currency fluctuations against the US Dollar and Yen. Most of SABESP's liabilities in foreign currency include loans denominated in US Dollars and Yen.

In the case of Real depreciation against the foreign currency in which debt is denominated, SABESP will incur monetary loss in relation to this debt.

SABESP’s specific foreign exchange risks are related to exposures caused by its short and long-term foreign currency-denominated debt.

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

This risk arises from the possibility that the Company may incur losses due to exchange rate fluctuations that would have an impact on 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 to hedge against this risk, but conducts an active management of debt, taking advantage of opportunities to swap expensive debts with “cheaper” debts, reducing the cost through early maturity.

A significant amount of the Company’s financial debt is indexed to the US Dollar and Yen, in the total amount of R$3,189.1 million on June 30, 2012 (R$2,437.2 million on June 30, 2011). The Company’s exposure to foreign exchange risk is the following:

Page 3 6 of 94

Notes to the Financial Statements

	June 30, 2012 — Foreign currency	R$	June 30, 2011 — Foreign currency	R$
Loans and financing – US$	1,093,537	2,210,366	1,056,236	1,648,890
Loans and financing – Yen	38,479,341	974,682	40,489,000	785,081
Loans and financing interest and charges – US$		12,219		11,812
Loans and financing interest and charges – Yen		6,601		4,089
TOTAL		3,203,868		2,449,872

The chart above details the foreign currency-denominated loans and financing. The total of R$14,742 on June 30, 2012 (June 2011 - R$12,618) includes funding costs.

On June 30, 2012, if the Real had appreciated or depreciated by 10% compared to the U.S. dollar and the Yen with all other variables kept afloat, the effect on income after taxes and shareholders’ equity for the period would have been approximately R$211,455 (June 2011– R$161,691), mainly as a result of foreign currency gains or losses with the conversion of foreign currency-denominated loans.

Simulation of appreciation/depreciation of the Real by 10% — Foreign currency-denominated loans and interest rates	3,203,868	2,449,872
US Dollar/Yen variation	10%	10%
Appreciation or depreciation of the Real	320,387	244,987
Income tax/social contribution rate	34%	34%
Income tax/social contribution	108,932	83,296
Appreciation or depreciation of the Real, net of taxes	211,455	161,691

Interest rate risk

This risk derives from the possibility that the Company may incur in losses due to interest rate fluctuations that increase financial expenses related to loans and financing.

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

Below is the Company’s loans and financing expressed in Reais subject to variable interest rates:

(i) UPR – Reference Standard Unit (ii) CDI – Interbank Deposit Certificate (iii) IGP-M – General Market Price Index (iv) TJLP – Long-Term Interest Rate (v) IPCA – Extended Consumer Price Index

Another risk faced by the Company is the non-correlation between the monetary adjustment indexes of its debt and services revenues. Water supply and sewage treatment tariff adjustment do not necessarily follow the increases in loans and financing adjustment indexes and interest rates affecting the Company’s debt.

On June 30, 2012, if interest rates on Reais-denominated loans had changed around 1%, with all other variables kept the same, the effect on income after taxes in the six-month period would have been approximately R$34,302 (June 2011 – R$36,883), mainly as a result of lower or higher interest expenses in variable rate loans.

(b) Credit risk

The credit risk results from cash equivalents, bank and financial institution deposits, as well as credit exposure to customers, including outstanding accounts receivable. By force of law, the Company shall invest its cash surplus exclusively with Banco do Brasil (rating AA+(bra)). The credit risks are mitigated by sales to a widely and geographically spread customer base.

The maximum exposure to credit risk on the reporting date is the carrying amount of securities classified as cash equivalents, deposits at Banks and financial institutions, trade accounts receivable, balances with related parties and indemnities on the balance sheet date. See Notes 5 to 9.

The Company’s liquidity mainly relies on cash generated by operating activities, loans with financial institutions of the state and federal governments and financing in the local and international markets. The liquidity risk management considers the assessment of liquidity requirements to ensure that the Company has enough cash to meet its operating and capital expenditures.

Notes to the Financial Statements

The cash surplus held by the Company is invested in interest-bearing current accounts, time deposits, short-term deposits and marketable securities, electing instruments with proper maturities or sufficient liquidity to provide enough margin as determined by the aforementioned estimates .

The table below analyzes the Company’s financial liabilities, by maturity dates, including the amounts of principal and interest rates to be paid in accordance with contractual clauses.

(d) Sensitivity analysis

A chart follows that shows the sensitivity analysis of the financial instruments, prepared in accordance with CVM Rule 475/2008 in order to provide evidence of the balances of the main financial liabilities, calculated at a rate projected until the final settlement of each contract, converted into market value (Scenario I) with 25% appreciation (Scenario II) and 50% appreciation (Scenario III).

This sensitivity analysis has as its objective measuring the impact of changes in market variables on the said financial instruments of the Company, considering constant all other market indicators. These amounts, when settled, may differ from those provided above, due to estimates applied in the preparation process.

Notes to the Financial Statements

(i)	The contracts with Banco do Brasil and CEF were projected until final maturity, at contractual rates (Projected TR + spread) and discounted at present value by TR x DI; both rates were obtained from BM&F. For Scenarios II and III, deteriorations of 25% and 50%, respectively, were considered in discount rates;
(ii)	Debentures were projected until final maturity date (IPCA, DI, TJLP or TR) discounted at present value at forward market of interest rates, published by ANBIMA in the secondary market and with June 30, 2012 as the reference date and the Company’s securities traded in the domestic market. For Scenarios II and III, deteriorations of 25% and 50%, respectively, were considered in discount rates. For Debentures indexed to DI, a sensitivity analysis was conducted based on 25% and 50% increase of the DI market’s curve.
(iii)	Contracts with IDB, IBRD were projected until final maturity in original currency, using the contractual interest rates, discounted at present value using the forward Libor rate at Bloomberg. Eurobonds were priced at market value according to the quotes published by Bloomberg.
	Eurobonds were priced at market value according to the quotes at Bloomberg. All amounts obtained were converted into Reais at the exchange rate on June 30, 2012. For Scenarios II and III, we considered 25% and 50% increases, respectively, in exchange rates;
(iv)	The contracts with JICA were projected until the final maturity in original currency, using the interest rates contracted and discounted at present value, using the forward Tibor rate at Bloomberg. The amounts obtained were converted into Reais using the exchange rate on June 30, 2012. For Scenarios II and III were considered 25% and 50% increases, respectively, in exchange rates;
(v)	Financing – BNDES are instruments considered by face value adjusted until maturity date, which are indexed by TJLP, which is a specific mode not compared to any other market rate. Therefore, the Company has elected to report as market value the amount recorded on June 30, 2012. For that reason, the Company does not carry out a risk analysis for these contracts.

(e) Credit quality of the financial assets

The credit quality of the financial assets that are not past-due or are subject to provision for impairment may be assessed by reference to the external credit ratings (if any) or to the historic information on default ratio of the counterparties. For the credit quality of the counterparties which are financial institutions, such as deposits and financial investments, the Company considers the lowest rating of the counterparty disclosed by the three main international credit rating agencies (Moody’s, Fitch and S&P), pursuant to in-house policy for market risk management:

3.2 Capital management

The Company’s objectives when managing its capital are to safeguard its capacity of continuing to offer returns to shareholders and benefits to the other stakeholders, in addition to maintaining an ideal capital structure to reduce this cost.

The Company monitors capital based on financial leverage ratios. This ratio corresponds to the net debt divided by total capital. The net debt, in turn, corresponds to total loans and financing less cash and cash equivalents. Total capital is calculated through the sum of shareholders’ equity, as evidenced in the parent company’s balance sheet, with net debt.

	PARENT COMPANY — June 30, 2012	December 31, 2011
Total loans and financing	8,386,466	8,423,332
Less: cash and cash equivalents	(1,743,447)	(2,142,079)
Net debt	6,643,019	6,281,253
Total equity capital	11,042,477	10,545,896
Total capital	17,685,496	16,827,149
Leverage ratio	38%	37%

Page 4 1 of 94

Notes to the Financial Statements

	CONSOLIDATED — June 30, 2012	December 31, 2011
Total loans and financing	8,569,740	8,596,295
Less: cash and cash equivalents	(1,752,485)	(2,149,989)
Net debt	6,817,255	6,446,306
Total equity capital	11,042,477	10,545,896
Total capital	17,859,732	16,992,202
Leverage ratio	38%	38%

On June 30, 2012, the parent company’s leverage ratio increased from 37% to 38%, due to the decrease in cash and cash equivalents, primarily a result of the payment of Interest on Equity in the period. The leverage ratio did not change in the consolidated results.

3.3 Fair value estimate

Trade accounts receivable and payable at carrying amount, less impairment, are supposed to approximate their fair values.

The fair value was measured in accordance with the following hierarchy of fair value measurement:

· Quoted prices (not adjusted) in active markets for identical assets and liabilities (level 1).

· Information, in addition to prices quoted included in level 1, which are adopted by the market for assets or liabilities, whether directly, such as prices, or indirectly, derived from prices (level 2).

· Inserts for asset or liability that are not based on data adopted by the market, i.e. non- observable inserts (level 3).

The single financial instrument measured at fair value by the Company is represented by short-term investments in bank deposit certificates (CDB), classified as cash equivalents, in the amounts of R$1,614,547 and R$2,027,785 on June 30, 2012 and December 31, 2011 (parent company) and R$1,623,273 and R$2,031,122 on June 30, 2012 and December 31, 2011 (consolidated), respectively. These investments are financial assets measured at fair value through profit or loss, measured in accordance with level 2.

3.4 Financial instruments

The Company operates with several financial instruments, pointing out cash and cash equivalents, including financial investments, and loans and financing as described below.

Estimated fair values of financial instruments are the following:

Contractors and suppliers	195,275	195,275	255,557	255,557

To obtain fair value of loans and financing, the following criteria have been adopted:

(i)	The contracts with Banco do Brasil and CEF (Federal Savings Bank) were projected until final maturity at contractual rates (TR projected + spread) and discounted at present value by TR x DI; both rates were obtained from BM&F.
(ii)	Debentures were projected until final maturity date (IPCA, DI, TJLP or TR) discounted at present value at forward market interest rates published by ANBIMA in the secondary market and with June 30, 2012 as the reference date and the Company’s securities traded in the domestic market.
(iii)	Financing – BNDES are instruments considered by face value adjusted until maturity date, which are indexed by TJLP, which is a specific mode not compared to any other market rate. Therefore, the Company has elected to report as market value the amount recorded on June 30, 2012.

Page 4 3 of 94

Notes to the Financial Statements

(iv)	Other financing in domestic currency is considered by face value adjusted until maturity date, discounted at present value using the forward market of interest rates. Forward rates were obtained from the BM&FBovespa website.
(v)	The contracts with IDB, IBRD were projected until final maturity in original currency, using contractual interest rates and discounted at present value applying the forward Libor rate at Bloomberg. Eurobonds contracts were priced by market quotes published by Bloomberg. All the amounts obtained were converted into Reais at the exchange rate on June 30, 2012.
(vi)	The contracts with JICA were projected until final maturity in original currency, using contractual interest rates and discounted at present value, applying the forward Tibor rate at Bloomberg. The amounts obtained were converted into Reais at the exchange rate on June 30, 2012.
(vii)	Leasing is an instrument considered by its face value updated until the maturity date and indexed by a contractual fixed rate, which is a specific mode not to be compared to any other market rate. Therefore, the Company reports as market value the amount recorded on June 30, 2012.

MAIN ACCOUNTING JUDGMENTS AND ESTIMATES

The estimates and judgments are continuously evaluated based on historical experience and other factors, including the expectations of future events believed to be reasonable under the circumstances. There was no change in relation to the Annual Financial Statements on December 31, 2011, according to Note 5.

CASH AND CASH EQUIVALENTS

	PARENT COMPANY — June 30, 2012	December 31, 2011	CONSOLIDATED — June 30, 2012	December 31, 2011
Cash and banks	128,900	114,794	129,212	118,867
Cash equivalents	1,614,547	2,027,285	1,623,273	2,031,122
	1,743,447	2,142,079	1,752,485	2,149,989

The variation in the period from January to June 2012 derives from operating cash flow of the Company’s activities.

In June, the average yield of financial investments corresponded to 100.2% of CDI.

RESTRICTED CASH

On June 30, 2012, the Company recorded restricted cash, in current assets, in the amount of R$90,847, of which R$8,280 refer to BNDES collateral, R$465 was blocked due to court decision and R$82,102 refers to the collection deriving from services rendered to parties related to the municipal government of São Paulo, net of taxes. These funds should be reinvested in the water and sewage systems of the city of São Paulo.

The variation occurring in the period from January to June 2012, when compared to the Financial Statements of December 31, 2011, is mainly due to the decrease in the balance of the São Paulo Municipal Government’s account.

(i) Water and sewage services

The Company provides water supply and sewage collection services to the State Government and other Companies related thereto, under terms and conditions considered by Management as usual in the market, except as to the form of settlement of the credits that may occur under the conditions mentioned in items (iii), (iv) and (v).

Page 48 of 94

Notes to the Financial Statements

(ii) Reimbursement of supplementary retirement and pension benefits paid

This refers to additional amounts of retirement and pension plan benefits provided for in the State of São Paulo’s Law 4819/58 (the Benefits) paid by the Company to former employees or retirees.

Pursuant to the Agreement referred to in (iii), GESP is recognized to be liable for the charges deriving from Benefits, provided that payment criteria are observed, established by the Personnel Expense State Department – DDPE, based on legal guidance provided by Legal Consulting of the Treasury Department and the State Attorney General’s Office – PGE.

As explained in item (vi) during the validation by GESP of the amounts due to the Company related to Benefits, discrepancies were raised as to the calculation criteria and eligibility of Benefits applied by the Company.

On June 30, 2012 and December 31, 2011, 2,489 and 2,492 retirees, respectively, received additional retirement, and in the quarters ended June 30, 2012 and December 31, 2011, the Company paid R$30,456 and R$39,061, respectively. There were 11 active employees on June 30, 2012, who will be eligible to these benefits upon retirement, as compared to 14 on December 31, 2011.

In January 2004, supplementary retirement and pension payments were transferred to the Treasury Department and would be made according to calculation criteria defined by PGE. Due to court decision, the responsibility for the payments returned to SABESP as originally established.

(iii) GESP Agreement

On December 11, 2001, the Company, GESP (through the State Department of Treasury Affairs, currently the Treasury Department) and the Department of Water and Electric Power – DAEE, and the Department of Water Resources, Sanitation and Works, currently the Department of Sanitation and Water Resources, as an intervening party, entered into the Instrument of Recognition and Consolidation of Obligations, Payment Commitment and Other Covenants (the GESP Agreement) aiming at solving pending issues between GESP and the Company related to water and sewage services with regard to Benefits.

In view of the strategic relevance of the reservoirs in Taiaçupeba, Jundiaí, Biritiba, Paraitinga and Ponte Nova (the Reservoirs), to guarantee the maintenance of water volume of Alto Tiete, the Company agreed to receive them as part of the reimbursement referring to the Benefits. The Reservoirs would be transferred to the Company by DAEE, which in turn would subrogate under credit the same amount with GESP. However, the Public Prosecution Office of the State of São Paulo contested the legal validity of this agreement, whose main argument is the lack of specific legislative authorization for the disposal of DAEE’s assets. The Company’s legal counsels assess the risk of losses as probable, if it does not obtain said legislative authorization, which would prevent the transfer of respective Reservoirs as partial amortization of balance receivable.

Notes to the Financial Statements

(iv) First Amendment to the GESP Agreement

On March 22, 2004, the Company and the State Government amended the terms of the original GESP Agreement, (1) consolidating and recognizing the amounts due by the State Government for water supply and sewage collection services rendered, adjusted for inflation, until February 2004; (2) formally authorizing the offset of amounts due by the State Government with interest on equity declared by the Company and any other debit with the State Government as at December 31, 2003, adjusted for inflation, until February 2004; and (3) defining the payment conditions of remaining liabilities of the State Government for the water supply and sewage collection services rendered.

(v) Second Amendment to the GESP Agreement

On December 28, 2007, the Company and the State of São Paulo through the Treasury Department signed the second amendment to the original GESP agreement on the installment payment of the remaining balance of the First Amendment, amounting to R$133,709 on November 30, 2007 to be paid in 60 equal monthly and consecutive installments, beginning on January 2, 2008. The amount of installments is adjusted for inflation according to the IPCA-IBGE variation, plus monthly interest of 0.5%.

The State Government and SABESP agreed to immediately resume the compliance with their mutual obligations under new assumptions: (a) implementation of an electronic account management system to facilitate and speed up the monitoring of payment processes and budget management procedures; (b) structuring of the PURA to rationalize the consumption of water, water and sewage bills under the responsibility of the State Government; (c) establishment, by the State Government, of budget criteria so as to avoid the reallocation of amounts to a specific water and sewage account as of 2008; (d) possibility of registering state authorities and entities in a delinquency system or reference file; (e) possibility of interrupting water supply to state authorities and entities in the event of failure to pay water and sewage bills.

(vi) Third Amendment to the GESP Agreement

On November 17, 2008, GESP, SABESP and DAEE, entered into the Third Amendment to the GESP Agreement, and acknowledged to owe to SABESP the amount of R$915,251, adjusted for inflation until September, 2008 by IPCA-IBGE, corresponding to the Undisputed Amount, calculated by FIPECAFI (Institute Foundation of Accounting, Actuarial and Financial Researches). SABESP temporarily accepted the Reservoirs (see item (iii) above) as part of the payment of the Undisputed Amount and offered to temporary settlement to GESP, establishing a financial credit of R$696,283, corresponding to the value of the Reservoirs at Alto Tietê System. The Company did not recognize the amount receivable of R$696,283 related to the Reservoirs, as their transfer by the State Government is uncertain. The final settlement will only occur with the effective transfer of ownership at the appropriate real estate registry office. The remaining balance of R$218,967 has been paid in 114 monthly and consecutive installments, in the amount of R$1,920 each, annually adjusted by the IPCA/FIPE, plus monthly interest rate of 0.5%, the first installment due on November 25, 2008.

SABESP and the State Government of São Paulo are working together in order to obtain the legislative authorization so that to make feasible the transfer of Reservoirs to SABESP, thus, overcoming the legal uncertainty caused by the public civil action that contends the lack of specific legislation for the transfer of Reservoirs ownership.

The Third Amendment also provides for the regularization of the monthly flow of benefits. While SABESP is responsible for the monthly payments, the State Government shall reimburse the Company based on criteria identical to those applied in the calculation of the Undisputed Amount. With no preventive court decision, the State Government will directly bear the monthly payment flow of the amount considered undisputed.

(vii) Controversial Amount of Benefits

As mentioned before, on November 17, 2008, the Company and the State Government signed the Third Amendment to the GESP Agreement, when controversial and undisputed amounts were quantified. Efforts were endeavored to settle the referred Controversial Amount of Benefits. According to clause four of this instrument, the Controversial Amount is represented by the difference between the Undisputed Amount and the amount effectively paid by the Company as supplementary retirement and pension benefits provided for by Law 4819/58, of original responsibility of the State Government but paid by SABESP by court decision.

The Third Amendment provides that PGE will re-analyze discrepancies that gave rise to the Controversial Amount of Benefits provided for by Law 4819/58. At that time, this expectation was based on the PGE’s intention to re-analyze the matter and also in the Company’s right to reimbursement, inclusively based on external technical legal opinions.

However, new opinions issued by PGE and received on September 4 and 22, 2009 and January 4, 2010, denied the reimbursement of the amount previously defined as a Controversial Amount.

Although negotiations with the State Government are still being maintained, it is no longer possible to ensure that the Company will recover, on a fully amicable basis, the credits related to the Controversial Amount.

As part of the actions intended to recover the credit the Management understands as due by the State Government related to the discrepancies about the reimbursement of supplementary retirement and pension benefits paid by the Company, SABESP: (i) addressed, on March 24, 2010, a message to the controlling shareholder, forwarding an official letter released by the Joint Committee, proposing arbitration action by common agreement to be sent to the Arbitration Panel of Bovespa (São Paulo Stock Exchange); (ii) in June, 2010, a settlement proposal aiming at solving these pending issues has been sent to the Treasury Department. This proposal was not successful; (iii) on November 9, 2010, a lawsuit was filed against the State Government of São Paulo pleading the full reimbursement of amounts paid as benefits provided by for by State Law 4819/58 which will allow to definitively settle the referred to Controversial Amount between the Company and GESP. Despite the lawsuit, the Company will insist on reaching an agreement during the progress of the lawsuit, understanding that a reasonable agreement is better to the Company and its shareholders than awaiting the conclusion of the lawsuit.

The Company’s Management opted for not recognizing these amounts, due to the uncertainty involving the reimbursement by the State Government. On June 30, 2012 and December 31, 2011, the amounts not recorded under assets referring to the supplementary retirement and pension benefits paid totaled R$1,317,460 and R$1,290,663, respectively, including the amount of R$696,283 referring to the transfer of Reservoirs at Alto Tietê system. The Company also recognized the actuarial liability referring to the supplementary retirement and pension maintained with employees and pensioners of Plan G0. On June 30, 2012 and December 31, 2011, the amounts corresponding to this actuarial liability totaled R$1,537,025 and R$1,512,078, respectively. For more information on the supplementary retirement and pension liabilities, see Note 16.

(b) Agreement for the use of reservoirs

In its operations, the Company uses the Guarapiranga and Billings reservoirs owned by another company controlled by the State Government. Should these Reservoirs have not been available for use by the Company, then maybe water would have had to be caught in distant locations. The Company does not pay any fee for the use of these Reservoirs, but it is liable for their maintenance and operating costs.

The Company has contracts signed with government authorities related to the State Government and municipalities operated, which are benefited with a 25% reduction in the tariff of water supply and sewage collection services, when on performance. The contracts provide for the implementation of PURA, which considers the reduction in water consumption.

(d) Collaterals

The State Government grants collateral for some of the loans and financing of the Company and does not charge any fee related thereto.

(e) Agreement for the assignment of personnel among GESP’s related entities

The Company has agreements for the assignment of employees with entities related to the State Government of São Paulo, where expenses are fully transferred and monetarily reimbursed. On June 30, 2012, the expenditures with employees assigned by SABESP to other state entities amounted to R$ 3,369 (June 2011 - R$2,962).

(f) Services contracted from GESP’s related entities

On June 30, 2012 and December 31, 2011, SABESP had outstanding amounts of R$3,967 and R$12,062, respectively, payable referring to services rendered by entities related to the State Government of São Paulo. Among them, we highlight electricity supply services rendered by the Companhia Energética de São Paulo – CESP, accounting for 63% of the amount on June 30, 2012.

(g) Non-operating Assets

On June 30, 2012 and December 31, 2011, the Company had the amount of R$969 relating to land assigned in loan for use of the Department of Water and Electricity (DAEE).

(h) SABESPREV

The Company sponsors the Defined Benefit Plan operated and managed by Fundação SABESP de Seguridade Social - SABESPREV. The net actuarial liability recognized up to June 30, 2012, was R$557,299 (December 2011 – R$538,619).

(j) Loan agreement through credit facility

The Company holds interest in certain Special Purpose Entities (SPE), holding the majority interest but with a casting vote and power of veto in certain issues. Therefore, these SPEs are considered for accounting purposes jointly-owned subsidiaries, and are proportionally consolidated pursuant to CPC 19.

These SPEs were created to execute specific projects and will be liquidated after their completion.

The Company entered into a loan agreement through credit facility with the SPEs Águas de Andradina S.A., Águas de Castilho S.A. Aquapolo Ambiental S.A. to finance the operations of these companies, until the loans and financing required to banks is cleared. The contracts signed on January 19, 2012 with Águas de Andradina and Águas de Castilho and on March 30, 2012 with Aquapolo Ambiental have the following characteristics:

SPE	Credit Limit	Disbursed amount	Interest rate	Maturity
Águas de Andradina	R$1,050 thousand	R$1,049 thousand	CDI + 1.16 % p.m.	07/17/2012
Águas de Castilho	R$480 thousand	R$480 thousand	CDI + 1.16% p.m.	07/17/2012
Aquapolo Ambiental	R$24.6 million	R$24.6 million	CDI + 1.24% p.m.	04/30/2016

The amount disbursed is recognized in Current Assets under “Other Receivables” and amounts to R$26,158 on June 30, 2012. On the same date, financial income was affected by interest on these loans, amounting to R$693.

INDEMNIFICATIONS RECEIVABLE

Indemnifications receivable is a non-current asset representing amounts receivable from the municipality of Diadema as indemnification for the one-sided withdrawal of the Company’s water and sewage services concession in 1995. On June 30, 2012 and December 31, 2011, this asset amounted to R$60,295. On December 31, 2010, the balance of indemnification receivable was R$146,213, representing the municipalities of Diadema and Mauá in the amounts of R$60,295 and R$85,918, respectively.

The Company invested in the construction of water and sewage systems in the municipalities of Diadema and Maua to meet its concession service commitments. For the one-sided termination of concessions in Diadema and Maua, the municipalities took over the responsibility of providing water and sewage services in those areas. At that moment, the Company reclassified the fixed asset balances related to the assets used in those municipalities to non-current assets (indemnifications receivable).

The residual amount of items of the fixed assets related to the municipality of Diadema, reclassified in December 1996, was R$75,231 and the balance of indemnifications receivable from the municipality is R$60,295 on June 30, 2012.

SABESP filed lawsuits to collect amounts due by the municipalities. Regarding Diadema, a settlement was proposed between Diadema municipal government and Companhia de Saneamento de Diadema – Saned for the payment of indemnification, and a motion to stay execution was filed by Diadema municipal government. In July 2008, pledge of money was authorized in Saned’s bank accounts and financial investments (online pledge) up to 10% of the debt’s adjusted amount, and the amount of R$2,919 was blocked and withdrawn on March 3, 2009. Subsequently, the Court of Justice resolved that the pledge should be made upon weekly deposits by Saned of the amount corresponding to 20% of everything receives in its accounts and financial investments. Saned filed appeals against this decision, and currently interlocutory appeal filed at the Federal Supreme Court is pending judgment.

Notes to the Financial Statements

In the motion to stay execution filed by the municipality of Diadema, a court decision was rendered in October, 2009, recognizing the existence and enforceability of the debt and affirming that the execution against the Municipality should be made through a certificate of judgment debt of the government. SABESP and the municipal government appealed against this decision. SABESP obtained a favorable decision in September, 2011 from the Special Department of the Court of Justice, affirming to be constitutional the municipal law that allowed blocking the transfers of ICMS made by the State Government to the municipality (instead of payment only through certificate of judgment debt of the government).

On December 29, 2008, Saned and the municipality of Diadema jointly with the São Paulo State Government entered into a Memorandum of Intent aiming at preparing studies and conducting negotiations to instruct decisions of Diadema and SABESP, aiming at the exclusive rendering of water and sewage services in the municipality of Diadema.

The parties agree that the pursuit of a negotiated solution for the conflicts currently existing between the companies is indispensable so that water supply, sewage collection and treatment public utility have their proper development in the city of Diadema.

In January, 2009, the parties filed a joint motion pleading the suspension of new pledges, for a three-month period, in order to make feasible a settlement. The suspension was accepted by the Court of Public Treasury and successively renewed, the last renewal occurred in March 2012, in view of negotiations of the agreement.

A public civil action filed by the Public Prosecution Office of the State of São Paulo against the agreement based on the execution filed against the municipality of Diadema and Saned is pending judgment and since 2004 has been awaiting engineering and accounting expert examination. After negotiations initiated with the municipality of Diadema, the Public Prosecution Office pleaded the dismissal of the public civil action, which was rejected and will be the object of an appeal by SABESP.

Regarding Maua, a lower court decision was rendered determining that the Municipality pays the amount of R$153.2 million as compensation for the investments made in the municipality by SABESP and for loss of profits. This award was confirmed by the Federal Supreme Court, in final and un-appealable decision and SABESP has been taking measures to start execution.

The residual amount of fixed assets items related to the municipality of Maua, reclassified in December, 1999 was R$103,763 and the balance of indemnifications receivable from the municipality was R$85,918 on December 31,2010. Court decisions have been favorable to the Company and the receipt of amounts due by municipality will occur as a certificate of judgment debt of the government, which will be recognized upon effective receipt, in view of uncertainties related to the settlement of amounts involved and the track record related to prioritizing payments of certificate of judgment debt of the government in the municipality of Mauá. In December 2011, an accounting provision was recorded corresponding to the total amount of credit held by the Company and litigation still in progress.

Notes to the Financial Statements

Based on the opinion of the legal counsel, Management continues affirming that the Company has the legal right to receive the amounts corresponding to the indemnification and continues monitoring the status of legal proceedings.

Intangibles arising from concession contracts

The Company operates concession contracts including the rendering of basic and environmental sanitation, water supply and sewage collection services. These concession contracts establish rights and duties concerning the assets related to the rendering of public utilities (see Note 3.8 (a) of December 31, 2011). Contracts provide for assets that will reverse to the granting authority at the end of the concession period.

On June 30, 2012, the Company operated in 363 municipalities in the State of São Paulo. The concession period is 30 years in most of these municipalities.

Services fees occur in the form of tariffs, regulated by ARSESP.

Notes to the Financial Statements

Intangibles resulting from concession contracts include:

(i) Concession contracts – equity value

Concession contracts provide for the assets that will reverse to the granting authority at the end of the contract, for the residual value or market value in accordance with the terms of each contract. The amortization is calculated according to the straight-line method, which considers the useful life of assets.

(ii) Concession contracts - economic value

In the period between 1999 and 2006, negotiations related to new concessions were conducted considering the economic and financial result of the operation, determined in a valuation report issued by independent experts.

The amount determined in the respective contract, after a deal is closed with the municipal authorities, by means of subscription of the Company shares or in cash, is recorded in this item and is amortized by the respective concession period (usually 30 years). On June 30, 2012 there were no pending amounts related to these payments to the municipalities.

The amortization of intangible assets occurs during the effectiveness of contracts or by the useful life of concession underlying assets (whichever is shortest) by the straight-line method.

(iii) Program Contracts

This refers to the renewal of contracts previously referred to as concession contracts whose objective is water supply, sewage and sanitation services. Assets acquired or built are amortized during the contractual term (30 years) or during the useful life of underlying assets, whichever is shortest.

(iv) Program contracts - Commitments

After the enactment of the regulatory framework in 2007, renewals of concessions started to be made through program contracts. In some of these program contracts, the Company undertook the commitment to financially participate in social and environmental actions. The assets built and financial commitments assumed within the program contracts are recorded as intangible assets and are amortized by the straight-line method in accordance with the duration of the program contract (mostly, 30 years) or by the useful life of the assets, whichever is shortest.

On June 30, 2012, amortization expenses related to the commitments of the program contracts were R$8,063 (June 2011 – R$6,227).

The amounts not disbursed yet are recorded under “Program Contracts - Commitments” in current liabilities (R$43,592 and R$62,287 on June 30, 2012 and December 31, 2011, respectively) and non-current liabilities (R$135,842 and R$130,978 on June 30, 2012 and December 31, 2011, respectively).

Notes to the Financial Statements

(v) Services agreements – São Paulo

On November 14, 2007, the Company and the São Paulo Municipal Government (Parties) entered into an agreement to establish conditions to ensure stability in the rendering of basic and environmental sanitation public utilities in the municipality of São Paulo, whose main issues are:

(a) the Parties undertook the commitment of defining basic and environmental sanitation actions, complementing those of the São Paulo Municipality, investing in the implementation and continuity of programs, such as: the Clean Stream Program and PURA, whose main purpose is to ensure the reduction in water consumption in public units, assuring water supply and the quality of life of the population;

(b) as of November 14, 2007, the execution date of the agreement, the total amount paid by the São Paulo Municipality to SABESP, referring to direct Management bodies, independent governmental agencies and foundations, less taxes, shall be destined to basic and environmental sanitation actions in the municipality; and

(c) the municipality undertakes the commitment of resuming the payment of current bills and consumption bills issued by SABESP, as of November 14, 2007, the execution date of this agreement.

The agreement remains effective, but collection mentioned in item (b) is no longer allocated to a specific account for the allocation of basic and environmental sanitation actions in the municipality. The outstanding balance for the amounts collected but not allocated yet on June 30, 2012 was R$82,102 (December 2011 - R$90,984).

On June 23, 2010, the Company entered into an agreement with the State Government and the Municipality of São Paulo for the rendering of water supply and sewage public utilities in the municipality of São Paulo for a 30-year period, renewable for another 30 years.

On June 23, 2010, the State Government signed an agreement with the Municipal Government of São Paulo and the Company, as well as an agreement between the State Government and Municipal Government, and SABESP and ARSESP as intervening and consenting parties, whose main aspects are the following:

The State and the Municipal Government assign to SABESP the right to explore the rendering of sanitation services in the capital city of São Paulo, which includes the obligation of providing services and the right to fees through tariff revenues;
The State and the Municipal Government define ARSESP as liable for the regulation duties, including tariffs, control and monitoring of services;
The valuation model used was the discounted cash flow, which considered the economic and financial sustainability of SABESP operation in the metropolitan region of São Paulo;
Cash flows consider all operating costs, taxes, investments and remuneration of opportunity cost of investors and creditors of SABESP;
The agreement provides for investments corresponding to 13% of gross revenue obtained by services rendered in the municipality of São Paulo, net of COFINS e Pasep. Investment plans, referring to execution of SABESP shall be compatible with activities and programs foreseen in state, municipal sanitation plans and where applicable, metropolitan. The Investment Plan is not definitive and will be revised by Managing Committee every four years, especially as to investments to be made in subsequent period;

Page 61 of 94

Notes to the Financial Statements

The transfer to the Municipal Fund of Environmental Sanitation and Infrastructure to be applied in sanitation-related actions of the capital city establishes a charge to be recovered in tariff, according to contractual provision. This amount corresponds to 7.5% of gross revenues obtained from services rendered in the municipality of São Paulo, net of COFINS and PASEP and delinquency in the period;
The opportunity cost of investors and creditors of SABESP was established by WACC methodology (weighted average cost of capital). This cost was applied as the discount rate of cash flows; and
The agreement provides for the remuneration of operating net assets, preferably calculated through equity valuation or through monetarily restated carrying amount to be defined by ARSESP. In addition, the contract also provides for the remuneration of investments to be made by SABESP, so that there is no residual value at the expiration of the agreement.

The agreement with the municipality of São Paulo, which approximately accounts for 55.6% of the Company’s total revenues, ensures legal and equity safety to SABESP, proper return to shareholders and rendering of quality services to its customers.

The Municipal Government of São Paulo and the Company did not reach an agreement to solve pending financial issues until the execution date of the agreement, related to the rendering of water supply and sewage collection services to households of the municipality, reason that the Company filed suit against these bills, which are accrued for losses.

(vi) New Businesses

In August 2009, the Company entered into an agreement with CASAL - Companhia de Saneamento de Alagoas, to render specialized technical services in order to implement the program to reduce losses and revenue evasion in the municipality of Maceió, for a 60-month period. Services started to be rendered in 2010.

On June 30, 2012, the amount recorded under “New businesses” was R$14,463 (December 2011 - R$16,477) where the amount recorded for CASAL was R$13,124 on June 30, 2012 (December 2011 – R$15,665).

(a) Write-off of underlying assets of intangibles

On June 30, 2012, the Company wrote-off underlying assets of intangibles in the amount of R$1,755 (June 2011 - R$3,196) due to obsolescence, theft, disposal and works shut down, unproductive wells and projects economically unfeasible.

(b) Capitalized interests and other financial charges

On June 30, 2012, the Company capitalized interests and monetary variation, including exchange variation in the concession intangible assets in the amount of R$171,103 (June 2011 – R$132,505) during the period in which assets were reported as work in progress.

Page 62 of 94

Notes to the Financial Statements

The Company is the primary party responsible for the construction and installation of infrastructure related to concession, whether with its own efforts or through outsourced services, and it is significantly exposed to related risks and benefits.

Therefore, the Company recognizes construction revenue, corresponding to additional construction costs of gross margin. Generally, concession-related constructions are outsourced by the Company. In this case, the Company's implicit margin is usually lower to cover administration costs, as well as the assumption of primary risk. In 2012, the margin calculated was 2.3% (2.3% in 2011).

The amount of the construction margin (consolidated) for the six-month period ended June 30, 2012 and June 30, 2011 was R$24,603 and R$22,504, respectively.

(d) Expropriations

Due to the execution of priority works related to the water and sewage systems, the expropriation or establishment of right-of-way in third party properties was necessary, whose owners will be refunded on an amicable or court basis.

Assets, which are the subject-matter of these expropriations, must be registered in concession intangible assets once operation is completed. On June 30, 2012, the total amount referring to expropriations was R$8,090 (June 2011 - R$10,578).

(e) Assets pledged as collateral

On June 30, 2012, the Company held assets pledged as collateral in the amount of R$249,034 for the Special Tax Installment Payment – Paes (Note 13) (December 2011 – R$249,034).

(f) Public-Private Partnership - PPP

SABESP and CAB-Sistema Produtor Alto Tietê S/A, a special purpose entity composed of Galvão Engenharia S.A. and Companhia Águas do Brasil – CAB Ambiental, signed in June 2008 the Public-Private Partnership agreements of the Alto Tietê Producer System.

The service agreement has a 15-year term, aiming at expanding the capacity of the Taiaçupeba Water Treatment Station, from 10 to 15,000 liters per second, whose operations started in October 2011.

On June 30, 2012 and December 31, 2011, the carrying amount recorded in the Company’s intangible assets, related to PPP, was R$497,689 and R$474,818, respectively.

(g) Impairment

No provision for impairment was recorded on June 30, 2012 and December 31, 2011.

(h) Works in progress

Works in progress were recorded under intangible assets in the amount of R$5.1 billion on June 30, 2012 (December 31, 2011 - R$5.7 billion).

TAXES AND CONTRIBUTIONS

a) Current assets

The item recoverable taxes of current assets is composed of the outstanding balance of income tax and social contribution and amounts related to withholding income tax (IRRF) on financial investments. The consolidated balance on June 30, 2012 was R$86,355 (R$118,116 on December 31, 2011), a reduction of R$31,761 in the balance occurred as a result of offset of amounts related to outstanding balance of income tax and social contribution for the year 2011 with amounts payable of the same taxes for 2012. This drop was partially mitigated by the calculation of withholding income tax (IRRF) levied on financial investments interest income recognized in the quarter.

Transition Tax Regime – RTT

For the purposes of calculating income tax and social contribution on net income for the years 2009 and 2008, the Company and its subsidiaries adopted the RTT, which allows the legal entity to eliminate the accounting effects of Law 11,638/07 and Provisional Measure 449/08, converted into Law 11,941/09, by means of records in the tax accounting ledger - LALUR and ancillary controls, without any change in the accounting books.

In 2011 and 2010, the Company has also adopted the same tax practices of 2008 and 2009, since the RTT became mandatory and shall be effective until the enactment of Law that rules the tax effects of the new accounting methods, seeking tax neutrality.

Total	1,571,829	91,153	(166,981)	(78,227)	1,417,774

The consolidated balance amounts to R$1,417,779 (December 2011 – R$1,571,829). The R$5 difference when compared to the parent company’s balance refers to the provision of R$3 and R$2 recorded by the subsidiaries Águas de Andradina and Águas de Castilho, respectively.

The main variations occurring in the period additions are related to new provision, change in estimated loss related to customers, suppliers and labor claims. In the case of write-offs due to the revised estimate, payments are made in the six-month period and, for suppliers, relating to the agreement concluding the lawsuit.

(i) Customers - Approximately 1,520 lawsuits were filed by commercial customers, which claim that their tariffs should correspond to other consumer categories, and accordingly the refund of amounts charged by the Company. The Company was granted both favorable and unfavorable final decisions at several court levels and recognized provision when the chances of losses were probable.

(ii) Suppliers - Suppliers’ claims include lawsuits filed by some builders 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.

(iii) Other civil lawsuits - these mainly refer to action for damages due to property damage, pain and suffering, and loss of profits allegedly caused to third parties, filed at different court levels, duly accrued when classified as probable losses.

Page 76 of 94

Notes to the Financial Statements

(iv) Tax lawsuits - the provision for tax contingencies mainly refers to issues connected with tax collections questioned due to different interpretation of legislation by the Company’s legal counsels, duly accrued when classified as probable losses.

(v) Labor lawsuits - the Company is a party in several labor lawsuits, involving issues such as overtime, unhealthy work premium and hazardous work premium, prior notice, change of job position, salary parity and other. Most of the amount involved is under provisional or final execution at various court levels, and thus is classified as a probable loss and accordingly a provision was recognized.

(vi) Environmental lawsuits - these refer to several administrative proceedings and lawsuits filed by government entities, including Companhia de Tecnologia de Saneamento Ambiental – Cetesb, Public Prosecution Office of the State of São Paulo and other for the imposition of fines due to environmental damages allegedly caused by the Company. The accrued amounts do not always represent the final amount to be disbursed as indemnity of alleged damages, in view of the current stage of referred lawsuits and the impossibility of Management reasonably estimating the amounts of future disbursements.

Lawsuits with likelihood of possible loss

The Company is a party to lawsuits and administrative proceedings related to environmental, tax, civil and labor claims, which are considered by its legal counsels as possible losses, and are not recorded in the accounting books. The amount attributed to these lawsuits was approximately R$2,756,200 on June 30, 2012 (December 31, 2011 - R$2,621,800).

Other information is presented in the Annual Financial Statements of December 31, 2011.

EARNINGS PER SHARE

(a) Basic and diluted

Basic earnings per share are calculated by dividing the profit attributable to the Company’s shareholders by the weighted average number of common shares issued during the year.

	1H12	1H11
Profit attributable to the Company’s shareholders	784,724	662,441
Weighted average number of common shares issued (in thousands of shares)	227,836	227,836
Basic and diluted earnings per share (Reais per share)	3.44425	2.90753

The Company had no potential common shares outstanding, such as for instance, debt convertible into common shares. Thus, the basic and diluted earnings per share are the same.

Report on review of quarterly information

To the Board of Directors and Stockholders Companhia de Saneamento Básico do Estado de São Paulo - SABESP

Introduction

We have reviewed the accompanying parent company and consolidated interim accounting information of Companhia de Saneamento Básico do Estado de São Paulo - SABESP, included in the Quarterly Information Form (ITR) for the quarter ended June 30, 2012, comprising the balance sheet as at that date and the statements of income for the quarter and six-month period then ended and changes in equity and cash flows for the six-month period then ended, and a summary of significant accounting policies and other explanatory information.

Management is responsible for the preparation of the parent company interim accounting information in accordance with the accounting standard CPC 21, Interim Financial Reporting, of the Brazilian Accounting Pronouncements Committee (CPC), and of the consolidated interim accounting information in accordance with CPC 21 and International Accounting Standard (IAS) 34 - Interim Financial Reporting issued by the International Accounting Standards Board (IASB), as well as the presentation of this information in accordance with the standards issued by the Brazilian Securities Commission (CVM), applicable to the preparation of the Quarterly Information (ITR). Our responsibility is to express a conclusion on this interim accounting information based on our review.

Scope of review

We conducted our review in accordance with Brazilian and International Standards on Reviews of Interim Financial Information (NBC TR 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity and ISRE 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity, respectively). A review of interim 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 Brazilian and International 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 parent company interim information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying parent company interim accounting information included in the quarterly information referred to above has not been prepared, in all material respects, in accordance with CPC 21 applicable to the preparation of the Quarterly Information, and presented in accordance with the standards issued by the CVM.

Conclusion on the consolidated interim information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying consolidated interim accounting information included in the quarterly information referred to above has not been prepared, in all material respects, in accordance with CPC 21 and IAS 34 applicable to the preparation of the Quarterly Information, and presented in accordance with the standards issued by the CVM.

Statements of value added

We have also reviewed the parent company and consolidated statements of value added for the six-month period ended June 30, 2012. These statements are the responsibility of the Company's management, and are required to be presented in accordance with standards issued by the CVM applicable to the preparation of Quarterly Information (ITR) and are considered supplementary information under IFRS, which do not require the presentation of the statement of value added. These statements have been submitted 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 have not been prepared, in all material respects, in a manner consistent with the parent company and consolidated interim accounting information taken as a whole.
