All majority-owned subsidiaries in which we have both share and management control are consolidated. All significant intercompany accounts and transactions are eliminated. Subsidiaries over which control is achieved through other means, such as stockholders agreement, are also consolidated even if we hold less than 51% of voting capital. Our variable interest entities in which we are the primary beneficiary are consolidated. Investments in unconsolidated affiliates and joint ventures are accounted under the equity method (Note 9).

We evaluate the carrying value of our equity investments in relation to publicly quoted market prices when available. If the quoted market price is lower than book value, and such decline is considered other than temporary, we write-down our equity investments to the level of the quoted market value.

We define joint ventures as businesses in which we and a small group of other partners each participate actively in the overall entity management, based on a stockholders agreement. We define affiliates as businesses in which we participate as a noncontrolling interest but with significant influence over the operating and financial policies of the investee.

Our participation in hydroelectric projects in Brazil is made via consortium contracts under which we have undivided interests in the assets, and are liable for our proportionate share of liabilities and expenses, which are based on our proportionate share of power output.  We do not have joint liability for any obligations. No separate legal or tax status is granted to consortia under the Brazilian law. Accordingly, we recognize our proportionate share of costs and our undivided interest in assets relating to hydroelectric projects.

Summary of significant accounting policies

Basis of presentation

Our condensed consolidated interim financial statements for the three-month periods ended March 31, 2012, December 31, 2011 and March 31, 2011, prepared in accordance with accounting principles generally accepted in the United States of America (“USGAAP”), which differ in certain respects from the accounting practices adopted in Brazil (“BRGAAP”), and the International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standard Board (“IASB”), which are the basis for our annual statutory financial statements, are unaudited. However, in our opinion, these condensed consolidated financial statements includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results for interim periods. The results of operations for the three-month periods ended March 31, 2012, are not necessarily indicative of the actual results expected for the full fiscal year ending December 31, 2012.

These condensed consolidated interim financial statements should be read in conjunction with our audited consolidated financial statements as of and for the year ended December 31, 2011, prepared in accordance with US GAAP.

In preparing the condensed consolidated financial statements, we are required to use estimates to account for certain assets, liabilities, revenues and expenses. Our condensed consolidated financial statements therefore include various estimates concerning the selection of useful lives of property, plant and equipment, impairment, provisions necessary for contingent liabilities, fair values assigned to assets and liabilities acquired and assumed in business combinations, income tax uncertainties, employee post-retirement benefits and other similar evaluations. Actual results may vary from our estimates.

The Brazilian real is the parent Company’s functional currency. We have selected the US dollar as our reporting currency.

All assets and liabilities have been translated into US dollars at the closing rate of exchange at each balance sheet date (or, if unavailable, the first available exchange rate).  All statement of income accounts have been translated to US dollars at the average exchange rates prevailing during the respective periods. Capital accounts are recorded at historical exchange rates. Translation gains and losses are recorded in the Cumulative Translation Adjustments account (“CTA”) in stockholders’ equity.

The results of operations and financial position of our entities that have a functional currency other than the US dollar have been translated into US dollars and adjustments to translate those statements into US dollars are recorded in the CTA in stockholders’ equity.

The exchange rates used to translate the assets and liabilities of the Brazilian operations at March 31, 2012 and December 31, 2011, were R$1.8314 and R$1.8683, respectively.

Commitments and contingencies

15           Commitments and contingencies

a)  In regards to the construction and installation of our nickel and cobalt processing plant in New Caledonia, we have provided significant guarantees in respect of our financing arrangements which are outlined below.

In connection with the Girardin Act tax - advantaged lease financing arrangement sponsored by the French government, we provided guarantees to BNP Paribas for the benefit of the tax investors regarding certain payments due from VNC, associated with the Girardin Act lease financing. We also committed that assets associated with the Girardin Act lease financing would be substantially complete by December 31, 2011. In light of the delay in the start-up of the VNC processing facilities, we proposed an extension to the previously agreed substantial completion date of December 31, 2011 to December 31, 2012. The French Government and tax investors have formally agreed to this extension. We believe the likelihood of the guarantee being called upon to be remote.

Sumic Nickel Netherlands B.V. (“Sumic”), a 21% stockholder of VNC, has a put option to sell to us 25%, 50%, or 100% of the shares they own of VNC if the defined cost of the initial nickel cobalt development project, as measured by funding provided to VNC, in natural currencies and converted to U.S. dollars at specified rates of exchange, in the form of Girardin Act lease financing, shareholder loans and equity contributions by shareholders to VNC, exceeded $4.6 billion and an agreement cannot be reached on how to proceed with the project. On May 27, 2010 the threshold was reached. The put option discussion and decision period was extended to January 1, 2012 and we are in the process of finalizing a further extension. We are currently in discussion with Sumic on their continued participation in VNC, and expect to reach a resolution during the third quarter of 2012 following a prescribed process which occurs over a five month period.

In addition, in the course of our operations we have provided letters of credit and guarantees in the amount of US$762 million that are associated with items such as environment reclamation, asset retirement obligation commitments, insurance, electricity commitments, post-retirement benefits, community service commitments and import and export duties.

b)  We and our subsidiaries are defendants in numerous legal actions in the normal course of business. Based on the advice of our legal counsel, management believes that the amounts recognized are sufficient to cover probable losses in connection with such actions.

The provision for contingencies and the related judicial deposits is as follows:

	March 31, 2012 (unaudited)		December 31, 2011
	Provision for contingencies	Judicial deposits	Provision for contingencies	Judicial deposits
Labor and social security claims	788	928	751	895
Civil claims	303	171	248	151
Tax - related actions	682	433	654	413
Others	36	5	33	5
	1,809	1,537	1,686	1,464

Labor and social security related actions principally comprise of claims by Brazilian current and former employees for (i) payment of time spent travelling from their residences to the work-place, (ii) additional health and safety related payments and (iii) various other matters, often in connection with disputes about the amount of indemnities paid upon dismissal and the one-third extra holiday pay.

Civil actions principally relate to claims made against us by contractors in Brazil in connection with losses alleged to have been incurred by them as a result of various past Government economic plans, during which full inflation indexation of contracts was not permitted, as well as for accidents and land appropriation disputes.

Tax related actions principally comprise of challenges initiated by us, on certain taxes on revenues and uncertain tax positions. We continue to vigorously pursue our interests in all these actions but recognize that we probably will incur some losses in the final instance, for which we have made provisions.

Judicial deposits are made by us following court requirements in order to be entitled to either initiate or continue a legal action. These amounts are released to us upon receipt of a final favorable outcome from the legal action, and in the case of an unfavorable outcome, the deposits are transferred to the prevailing party.

Contingencies settled during the three-month periods ended March 31, 2012, December 31, 2011 and March 31, 2011, totaled US$13, US$643 and US$431, respectively. Provisions recognized in the three-month periods ended March 31, 2012, December 31, 2011 and March 31, 2011, totaled US$99, US$162 and US$54, respectively, classified as other operating expenses.

In addition to the contingencies for which we have made provisions, we are defendants in claims where in our opinion, and based on the advice of our legal counsel, the likelihood of loss is reasonably possible but not probable, in the total amount of US$23,201 at March 31, 2012, and for which no provision has been made (December 31, 2011 — US$22,449). The mainly reasonably possible tax contingencies refers to tax assessments against us regarding the payment of Income Tax and Social Contribution calculated based on the equity method in foreign subsidiaries.

c)             At the time of our privatization in 1997, the Company issued debentures to its then-existing stockholders, including the Brazilian Government. The terms of these debentures were set to ensure that the pre-privatization stockholders, including the Brazilian Government, would participate in possible future financial benefits that could be obtained from exploiting certain mineral resources.

A total of 388,559,056 Debentures were issued at a par value of R$ 0.01 (one cent), whose value will be restated in accordance with the variation in the General Market Price Index (IGP-M), as set forth in the Issue Deed. In March 31, 2012 the total amount of these debentures was US$ 1,460 (US$ 1,336 in December 31, 2011).

The debenture holders have the right to receive premiums, paid semiannually, equivalent to a percentage of net revenues from specific mine resources as set forth in the indenture.

In April 2012 (subsequent period) we paid remuneration on these debentures of US$ 6.

d)            Asset retirement obligations

We use various judgments and assumptions when measuring our asset retirement obligations.

Changes in circumstances, law or technology may affect our cash flow estimates and we periodically review the amounts accrued and adjust them as necessary. Our accruals do not reflect unasserted claims because we are currently not aware of any such issues. Also the amounts provided are not reduced by any potential recoveries under cost sharing, insurance or indemnification arrangements because such recoveries are considered uncertain.

The changes in the provisions for asset retirement obligations are as follows:

Fair value disclosure of financial assets and liabilities

Fair value disclosure of financial assets and liabilities

Fair value disclosure of financial assets and liabilities

17           Fair value disclosure of financial assets and liabilities

The Financial Accounting Standards Board, through Accounting Standards Codification and Accounting Standards Updates, defines fair value and sets out a framework for measuring fair value, which refers to valuation concepts and practices and requires certain disclosures about fair value measurements.

a)            Measurements

The pronouncements define fair value as the exchange price that would be received for an asset, or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants on the measurement date.  In determining fair value, the Company uses various methods including market, income and cost approaches.  Based on these approaches, the Company often utilizes certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and or the inherent risks in the inputs to the valuation technique.

These inputs can be readily observable, market corroborated, or generally unobservable inputs.  The Company utilizes techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.  Under this standard, those inputs used to measure the fair value are required to be classified on three levels. Based on the characteristics of the inputs used in valuation techniques the Company is required to provide the following information according to the fair value hierarchy.  The fair value hierarchy ranks the quality and reliability of the information used to determine fair values.  Financial assets and liabilities carried at fair value are classified and disclosed as follows:

Level 1 — Unadjusted quoted prices on an active, liquid and visible market for identical assets or liabilities that are accessible at the measurement date;

Level 2 - Quoted prices for identical or similar assets or liabilities on active markets, inputs other than quoted prices that are observable, either directly or indirectly, for the term of the asset or liability;

Level 3 - Assets and liabilities, for which quoted prices do not exist, or those prices or valuation techniques are supported by little or no market activity, unobservable or illiquid. At this point, fair market valuation becomes highly subjective.

b)            Measurements on a recurring basis

The description of the valuation methodologies used for recurring assets and liabilities measured at fair value in the Company’s Consolidated Balance Sheet at March 31, 2012 and December 31, 2011 are summarized below:

·              Available-for-sale securities

They are securities that are not classified either as held-for-trading or as held-to-maturity for strategic reasons and have readily available market prices. We evaluate the carrying value of some of our investments in relation to publicly quoted market prices when available.  When there is no market value, we use inputs other than quoted prices.

·              Derivatives

The market approach is used to estimate the fair value of the swaps discounting their cash flows using the interest rate of the currency they are denominated it is also used for the commodities contracts, since the fair value is computed by using forward curves for each commodity.

·              Debentures

The fair value is measured by the market approach method, and the reference price is available on the secondary market.

The tables below presents the balances of assets and liabilities measured at fair value on a recurring basis as follows:

	March 31, 2012 (unaudited)
	Carrying amount		Fair value		Level 1	Level 2
Unrealized gain on derivatives	31		31		—	31
Debentures	(1,460	)	(1,460	)	—	(1,460	)

	December 31, 2011
	Carrying amount		Fair value		Level 1	Level 2
Available-for-sale securities	7		7		7	—
Unrealized losses on derivatives	(81	)	(81	)	—	(81	)
Debentures	(1,336	)	(1,336	)	—	(1,336	)

c)             Measurements on a non-recurring basis

The Company also has assets under certain conditions that are subject to measurement at fair value on a non-recurring basis. These assets include goodwill and assets acquired and liabilities assumed in business combinations. During the three-month period ended March 31, 2012, we have not recognized any impairment for those items.

d)            Financial Instruments

Long-term debt

The valuation method used to estimate the fair value of our debt is the market approach for the contracts that are quoted on the secondary market, such as bonds and debentures. The fair value of both fixed and floating rate debt is determined by discounting future cash flows of Libor and Vale’s bonds curves (income approach).

Time deposits

The method used is the income approach, through the prices available on the active market. The fair value is close to the carrying amount due to the short-term maturities of the instruments.

Our long-term debt is reported at amortized cost, and the income of time deposits is accrued monthly according to the contract rate. The estimated fair value measurement is disclosed as follows:

	March 31, 2012
	Carrying amount		Fair value		Level 1		Level 2
Long-term debt (less interests) (*)	(23,986	)	(25,911	)	(19,452	)	(6,459	)

(*) Less accrued charges of US$ 365 and US$ 333 as of March 31, 2012 and December 31, 2011, respectively.

(**) Classified on “LT Loans and related parties” (Non current liabilities).

(Vale Fertilizantes) has approved the redemption of 5,314,386 remaining outstanding shares, including common and preferred, and representing 0.94% of total shares of Vale Fertilizantes. Thus, Vale now holds 100% of the total common shares and 100% of preferred shares of Vale Fertilizantes. For this transaction Vale paid US$ 76 and accounts an effect of US$ 10 on equity.

In February 2011, we concluded the transaction announced in May, 2010 with Norsk Hydro ASA (Hydro), to transfer all of our stakes in Albras-Alumínio Brasileiro S.A.

Stockholders' equity

12           Stockholders’ equity

Each holder of common and preferred class A stock is entitled to one vote for each share on all matters brought before stockholders’ meetings, except for the election of the Board of Directors, which is restricted to the holders of common stock. The Brazilian Government holds twelve preferred special shares which confer permanent veto rights over certain matters.

Both common and preferred stockholders are entitled to receive a mandatory minimum dividend of 25% of annual adjusted net income under Brazilian GAAP, once declared at the annual stockholders’ meeting. In the case of preferred stockholders, this dividend cannot be less than 6% of the preferred capital as stated in the statutory accounting records or, if greater, 3% of the Brazilian GAAP equity value per share.

In April 2012 (subsequent event), the Board of Directors approved the payment of interest on capital in the amount of US$ 3 billion, corresponding to US$ 0.588547644 per outstanding share, common or preferred shares, of Vale issuance.

In November 2011, a part of the to share buy-back program approved in June 2011, we concluded the acquisitions of 39,536,080 common shares, at an average price of US$ 26.25 per share, and 81,451,900 preferred shares, at an average price of US$ 24.09 per share (including shares of each class in the form of American Depositary Receipts), for a total aggregate purchase price of US$ 3.0 billion. The repurchased shares represent 3.10% of the free float of common shares, and 4.24% of the free float of preferred shares, outstanding before the launch of the program. The shares acquired will be held in treasury for cancellation.

The outstanding issued mandatory convertible notes as of March 31, 2012, are as follows:

	Date		Value
Headings	Emission	Expiration	Gross	Net of charges	Coupon
Tranches Vale and Vale P - 2012	July 2009	June 2012	942	934	6.75% p.a.

The notes pay a quarterly coupon and are entitled to an additional remuneration equivalent to the cash distribution paid to ADS holders.  These notes were classified as a capital instrument, mainly due to the fact that neither the Company nor the holders have the option to settle the operation, whether fully or partially, with cash, and the conversion is mandatory.  Consequently, they were recognized as a specific component of shareholders’ equity, net of financial charges.

The funds linked to future mandatory conversion, net of charges are equivalent to the maximum of common shares and preferred shares, are as follows. All the shares are currently held in treasury.

	Maximum amount of shares		Value
Headings	Common	Preferred	Common	Preferred
Tranches Vale and Vale P - 2012	18,415,859	47,284,800	293	649

In April 2012 (subsequent event), Vale approved the payment of additional remuneration to holders of mandatorily convertible notes, series    Vale-2012 and Vale P-2012, on April 30, 2012, in the amount of R$ 2.791486 and R$ 3.228658 per note, respectively.

Income taxes

6              Income taxes

Income taxes in Brazil comprise federal income tax and social contribution, which is an additional federal tax. The statutory composite enacted tax rate applicable in the periods presented is 34%. In other countries where we have operations, we are subject to various taxes rates depending on the jurisdiction.

We analyze the potential tax impact associated with undistributed earnings by each of our subsidiaries.  For those subsidiaries in which the undistributed earnings would be taxable when remitted to the parent company, no deferred tax is recognized, based on generally accepted accounting principles.

The amount reported as income tax expense in our consolidated financial statements is reconciled to the statutory rates as follows:

Vale and some subsidiaries in Brazil were granted with tax incentives that provide them with a partial reduction of the income tax due related to certain regional operations of iron ore, railroad, manganese, copper, kaolin and potash. The tax benefit is calculated based on taxable profit adjusted by the tax incentive (so-called “exploration profit”) taking into consideration the operational profit of the projects that benefit from the tax incentive during a fixed period. In general such tax incentives last for 10 years. The Company´s tax incentives will expire in 2020. The tax savings must be registered in a special capital (profit) reserve in the Stockholders’ equity of the entity that benefits from the tax incentive and cannot be distributed as dividends to the stockholders.

We are also allowed to reinvest part of the tax savings in the acquisition of new equipment to be used in the operations that have the tax benefit subject to subsequent approval from the Brazilian regulatory agencies Superintendência de Desenvolvimento da Amazônia - SUDAM and Superintendência de Desenvolvimento do Nordeste - SUDENE. When the reinvestment is approved, the corresponding tax benefit must also be accounted for in a special profit reserve and is also subject to the same restrictions with respect to future dividend distributions to the stockholders.

The Company also has tax incentives related to production of nickel from New Caledonia Valley (“VNC”). These incentives include tax holidays, total income tax during the construction phase of the project, and also for a period of 15 years beginning in the first year of commercial production as defined by applicable law, followed by 5.50% years. In addition, VNC is eligible for certain exemptions from indirect taxes such as import tax during the construction phase and throughout the commercial life of the project. Some of these tax benefits, including temporary tax incentives, are subject to an earlier, should the project achieve a specified cumulative rate of return. The VNC is subject to taxation of a portion of income commencing on the first year of commercial production is achieved, as defined by applicable law. Until now, there was no taxable income generated in New Caledonia. The Company also received tax incentives for projects in Mozambique, Oman and Malaysia.

We are subject to an examination by the tax authorities for up to five years regarding our operations in Brazil, up to ten years for Indonesia, and up to seven years for Canada for income taxes.

Tax loss carry forwards in Brazil and in most of the jurisdictions where we have tax loss carry forwards have no expiration date, though in Brazil, offset is restricted to 30% of annual taxable income.

The Company adopts the provision accounting for Uncertainty in Income Taxes.

The reconciliation of the beginning and ending amounts is as follows: (see note 15(b)) tax — related actions)

Long-term incentive compensation plan

Long-term incentive compensation plan

14           Long-term incentive compensation plan

Under the terms of the long-term incentive compensation plan, the participants, restricted to certain executives, may elect to allocate part of their annual bonus to the plan. The allocation is applied to purchase preferred shares of Vale, through a predefined financial institution, at market conditions and with no benefit provided by Vale.

The shares purchased by each executive are unrestricted and may, at the participant’s discretion, be sold at any time. However, the shares must be held for a three-year period and the executive must be continually employed by Vale during that period.  The participant then becomes entitled to receive from Vale a cash payment equivalent to the total amount of shares held, based on the market rates. The total shares linked to the plan at March 31, 2012 and December 31, 2011, are 4,880,468 and 3,012,538, respectively.

Additionally, as a long-term incentive certain eligible executives have the opportunity to receive at the end of the triennial cycle, a certain number of shares at market rates, based on an evaluation of their career and performance factors measured as an indicator of total return to stockholders.

We account for the compensation cost provided to our executives under this long-term incentive compensation plan, following the requirements for Accounting for Stock-Based Compensation. Liabilities are measured at each reporting date at fair value, based on market rates. Compensation costs incurred are recognized, over the defined three-year vesting period. At March 31, 2012, December 31, 2011, we recognized a liability of US$60, US$109, respectively, through the Statement of Income.

Risk management policy

Vale considers that the effective management of risks is a key objective to support its growth strategy, strategic planning and financial flexibility. Therefore, Vale has developed its risk management strategy in order to provide an integrated approach of the risks the Company is exposed to. To do that, Vale evaluates not only the impact of market risk factors in the business results (market risk), but also the risk arising from third party obligations with Vale (credit risk), those inherent to inadequate or failed internal processes, people, systems or external events (operational risk), those arising from liquidity risk, among others.

The Board of Directors established the corporate risk management policy in order to support the growth strategy, strategic planning and business continuity of the Company, strengthening its capital structure and asset management, ensure flexibility and consistency on the financial management and strengthen corporate governance practices.

The corporate risk management policy determines that Vale measures and monitors its corporate risk on a consolidated approach in order to guarantee that the overall risk level of the Company remains aligned with the guidelines defined by the Board of Directors and the Executive Board.

The Executive Risk Management Committee, created by the Board of Directors, is responsible for supporting the Executive Board in the risk analysis and for issuing opinion regarding the Company’s risk management. It’s also responsible for the supervision and revision of the principles and instruments of corporate risk management.

The Executive Board is responsible for the approval of the policy deployment into norms, rules and responsibilities and for reporting to the Board of Directors about such procedures.

The risk management norms and instructions complement the corporate risk management policy and define practices, processes, controls, roles and responsibilities in the Company regarding risk management.

The Company may, when necessary, allocate specific risk limits to management activities that need them, including but not limited to, market risk limit, corporate and sovereign credit limit, in accordance with the acceptable corporate risk limit.

Market Risk Management

Vale is exposed to the behavior of various market risk factors that can impact its cash flow. The assessment of this potential impact arising from the volatility of risk factors and their correlations is performed periodically to support the decision making process and the growth strategy of the Company, ensure its financial flexibility and monitor the volatility of future cash flows.

When necessary, market risk mitigation strategies are evaluated and implemented in line with these objectives. Some strategies may incorporate financial instruments, including derivatives. The portfolios of the financial instruments are monitored on a monthly basis, enabling financial results surveillance and its impact on cash flow, and ensuring strategies adherence to the proposed objectives.

Considering the nature of Vale’s business and operations, the main market risk factors which the Company is exposed to are:

· Interest rates;

· Foreign exchange;

· Product prices and input costs

Foreign exchange rate and interest rate risk

Vale’s cash flows are exposed to volatility of several currencies. While most of the product prices are indexed to US dollars, most of the costs, disbursements and investments are indexed to currencies other than the US dollar, namely the Brazilian real and the Canadian dollar.

Derivative instruments may be used to reduce Vale’s potential cash flow volatility arising from its currency mismatch.

For hedging revenues, costs, expenses and investment cash flows, the main risk mitigation strategies used are currency forward transactions and swaps.

Vale implemented hedge transactions to protect its cash flow against the market risks that arises from its debt obligations — mainly currency volatility. We use swap transactions to convert debt linked to Brazilian real into US dollar that have similar - or sometimes shorter - settlement dates than the final maturity of the debt instruments. Their notional amounts are similar to the principal and interest payments, subjected to liquidity market conditions.

Swaps with shorter settlement dates are renegotiated through time so that their final maturity matches - or becomes closer - to the debts` final maturity. At each settlement date, the results of the swap transactions partially offset the impact of the foreign exchange rate in Vale’s obligations, contributing to stabilize the cash disbursements in US dollar.

In the event of an appreciation (depreciation) of the Brazilian real against the US dollar, the negative (positive) impact on Brazilian real denominated debt obligations (interest and/or principal payment) measured in US dollars will be partially offset by a positive (negative) effect from a swap transaction, regardless of the US dollar / Brazilian real exchange rate in the payment date. The same rationale applies to debt denominated in other currencies and their respective swaps.

Vale is also exposed to interest rate risks on loans and financings. Its floating rate debt consists mainly of loans including export pre-payments, commercial banks and multilateral organizations loans. In general, the US dollar floating rate debt is subject to changes in the LIBOR (London Interbank Offer Rate in US dollar). To mitigate the impact of the interest rate volatility on its cash flows, Vale considers the natural hedges resulting from the correlation of commodities prices and US dollar floating rates. If such natural hedges are not present, Vale may search for the same effect by using financial instruments.

Product price and Input Cost risk

Vale is also exposed to several market risks associated with commodities prices volatility. In line with the risk management policy, risk mitigation strategies involving commodities can also be used to adjust its risk profile and reduce the volatility of cash flow. In these cases, the mitigation strategies used are primarily forward transactions, futures contracts or zero-cost collars.

Embedded derivatives

The cash flow of the Company is also exposed to market risks associated with contracts that contain embedded derivatives or behave as derivatives. The derivatives may be embedded in, but are not limited to, commercial contracts, purchase agreements, leases, bonds, insurance policies and loans.

Vale’s wholly-owned subsidiary Vale Canada Ltd has nickel concentrate and raw materials purchase agreements, in which there are provisions based on the movement of nickel and copper prices. These provisions are considered embedded derivatives.

Hedge Accounting

Under the Standard Accounting for Derivative Financial Instruments and Hedging Activities, all derivatives, whether designated in hedging relationships or not, are required to be recorded in the balance sheet at fair value and the gain or loss in fair value is included in current earnings, unless if qualified as hedge accounting. A derivative must be designated in a hedging relationship in order to qualify for hedge accounting. These requirements include a determination of what portions of hedges are deemed to be effective versus ineffective. In general, a hedging relationship is effective when a change in the fair value of the derivative is offset by an equal and opposite change in the fair value of the underlying hedged item. In accordance with these requirements, effectiveness tests are performed in order to assess effectiveness and quantify ineffectiveness for all designated hedges.

At March 31, 2012, Vale had outstanding positions designated as cash flow hedge. A cash flow hedge is a hedge of the exposure to variability in expected future cash flows that is attributable to a particular risk, such as a forecasted purchase or sale. If a derivative is designated as cash flow hedge, the effective portion of the changes in the fair value of the derivative is recorded in other comprehensive income and recognized in earnings when the hedged item affects earnings. However, the ineffective portion of changes in the fair value of the derivatives designated as hedges is recognized in earnings. If a portion of a derivative contract is excluded for purposes of effectiveness testing, the value of such excluded portion is included in earnings.

3              Summary of significant accounting policies

Our condensed consolidated interim financial statements for the three-month periods ended March 31, 2012, December 31, 2011 and March 31, 2011, prepared in accordance with accounting principles generally accepted in the United States of America (“USGAAP”), which differ in certain respects from the accounting practices adopted in Brazil (“BRGAAP”), and the International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standard Board (“IASB”), which are the basis for our annual statutory financial statements, are unaudited. However, in our opinion, these condensed consolidated financial statements includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results for interim periods. The results of operations for the three-month periods ended March 31, 2012, are not necessarily indicative of the actual results expected for the full fiscal year ending December 31, 2012.

These condensed consolidated interim financial statements should be read in conjunction with our audited consolidated financial statements as of and for the year ended December 31, 2011, prepared in accordance with US GAAP.

In preparing the condensed consolidated financial statements, we are required to use estimates to account for certain assets, liabilities, revenues and expenses. Our condensed consolidated financial statements therefore include various estimates concerning the selection of useful lives of property, plant and equipment, impairment, provisions necessary for contingent liabilities, fair values assigned to assets and liabilities acquired and assumed in business combinations, income tax uncertainties, employee post-retirement benefits and other similar evaluations. Actual results may vary from our estimates.

The Brazilian real is the parent Company’s functional currency. We have selected the US dollar as our reporting currency.

All assets and liabilities have been translated into US dollars at the closing rate of exchange at each balance sheet date (or, if unavailable, the first available exchange rate).  All statement of income accounts have been translated to US dollars at the average exchange rates prevailing during the respective periods. Capital accounts are recorded at historical exchange rates. Translation gains and losses are recorded in the Cumulative Translation Adjustments account (“CTA”) in stockholders’ equity.

The results of operations and financial position of our entities that have a functional currency other than the US dollar have been translated into US dollars and adjustments to translate those statements into US dollars are recorded in the CTA in stockholders’ equity.

The exchange rates used to translate the assets and liabilities of the Brazilian operations at March 31, 2012 and December 31, 2011, were R$1.8314 and R$1.8683, respectively.
