All relevant information for the preparation of these financial statements, and only this information, are presented and correspond to those used by the Company's Management. The financial statements have been prepared on a historical cost basis and adjusted to reflect: (i) the fair value of certain financial assets and liabilities (including derivative instruments), as well as pension plans assets and (ii) assets impairment. Assets held for sale are measured at the lower of carrying amount and fair value less costs to sell. These financial statements were authorized for issue by the Board of Directors on February 16, 2023. a) Principles for consolidation The Company's financial statements reflect the assets, liabilities and transactions of the Parent Company and its direct and indirect subsidiaries (“subsidiaries”). Intercompany balances and transactions, which include unrealized profits, are eliminated. A list of the most relevant companies, including subsidiaries, associates and joint ventures, and the accounting policies applied in the preparation of the consolidated financial statements are described in note 15. b) Functional currency and presentation currency The financial statements of the Company and its associates and joint ventures are measured using the currency of the primary economic environment in which the entity operates (“functional currency”), in the case of the Parent Company is the Brazilian real (“R$”). For presentation purposes, these financial statements are presented in United States dollar (“US$”) as the Company believes that this is how international investors analyze the financial statements. The income statement and cash flows statements of the investees, with a different functional currency from the Parent Company, are translated into Brazilian real at the average monthly exchange rate, the assets and liabilities are translated at the final rate and the other equity items are translated at the historical rate. All monetary exchange differences are recognized in comprehensive income as “Translation adjustments”. When a foreign operation is totally or partially disposed, the monetary exchange differences that were recorded in the equity are recognized in the income statement for the year, see accounting policy in note 15 of these financial statements. The main exchange rates used by the Company to translate its foreign operations are as follows: Schedule of exchange rates used to translate its foreign operations Closing rate Average rate 2022 2021 2020 2022 2021 2020 US Dollar ("US$") 5.2177 5.5805 5.1967 5.1655 5.3956 5.1578 Canadian dollar ("CAD") 3.8550 4.3882 4.0771 3.9705 4.3042 3.8480 Euro ("EUR") 5.5694 6.3210 6.3779 5.4420 6.3784 5.8989 c) Critical accounting estimates and judgments The preparation of financial statements requires the use of critical accounting estimates and Management also needs to exercise judgement in applying the Company’s accounting policies. The Company makes estimates about the future based on assumptions. Accounting estimates and judgments are continually evaluated and are based on management's experience and knowledge, information available at the date of the financial statements and other factors, including expectations of future events that are considered reasonable under the circumstances. Accounting estimates, by definition, will seldom equal the actual results. The areas involving significant estimates or judgements or complexity, and of items which are more likely to be materially adjusted due to estimates and assumptions are presented in the following notes: Note Significant estimates and judgments 7 Streaming transactions 8 Deferred income taxes and uncertain tax positions 15 Consolidation 18 Mineral reserves and mines useful life 19 Impairment of non-current assets 20 Fair values estimate 24 Liabilities related to Brumadinho 25 Liabilities related to associates and joint ventures 26 Provision for de-characterization of dam structures and asset retirement obligations 28 Litigation 29 Employee post retirement obligation d) A ccounting impacts related to environmental, social and governance initiatives (“ESG”) The Company has assumed commitments to integrate sustainability into its business through a comprehensive approach, based on systematic planning and execution.

Global markets are experiencing volatility and disruption following the escalation of geopolitical tensions in connection with the military conflict between Russia and Ukraine. The resulting economic sanctions imposed by the United States, Canada, the European Union, the UK and other countries as a direct consequence of this conflict may continue to significantly impact supply chains, lead to market disruptions including significant volatility in commodities’ prices and bring heightened near-term uncertainty to the global financial system, including through instability of credit and of capital markets. At this time, the effects of the Russia-Ukraine conflict have not caused significant impacts on the Company’s operations nor on the fair value of its assets and liabilities. However, escalation of the Russia-Ukraine conflict may adversely affect the Company’s business, such as disruption of international trade flows, extreme market pricing volatility, with particular impact on the energy sector, industrial and agricultural supply chains, shipping, and regulatory and contractual uncertainty, and increased geopolitical tensions around the world.

(ii) Includes the reclassification of the revenues of Midwestern System in the amount of US$231, for the year ended December 31, 2022 (2021: US$377 and 2020: US$162). Accounting policy Revenue A relevant proportion of Vale’s sales are under Cost and Freight (“CFR”) and Cost, Insurance and Freight (“CIF”) Incoterms, in which the Company is responsible for providing shipping services after the date that Vale transfers control of the goods to the customers. Shipping services for CFR and CIF contracts are considered as a separate performance obligation in which a proportion of the transaction price is allocated and recognized over time as the shipping services are provided. In general, the contract payment terms consider the upfront payments or the use of letters of credit. The payment terms do not have a significant financing component. In some cases, the sale price is determined on a provisional basis at the date of sale and adjustments to the sale price subsequently occur based on movements in the quoted market or contractual prices up to the date of final pricing. Revenue is recognized based on the estimated fair value of the total consideration receivable, and the provisionally priced sale mechanism embedded within these sale arrangements has the character of a derivative. Accordingly, the fair value of the final sale price adjustment is re-estimated continuously and changes in fair value are recognized as operational revenue in the income statement.

The incentive is calculated based on the taxable income of the incentive activity (tax operating income) and considers the allocation of tax operating income into different incentives applicable to different tranches of production during specified periods for each product, usually 10 In addition to these incentives, the income tax payable can be reduced by investing in the acquisition of new machinery and equipment, subject to subsequent approval by the responsible regulatory agency, Superintendence for the Development of the Amazon (“SUDAM”). This subsidy is expected to expire in 2023. As determined by the Brazilian law, the tax savings obtained as a result of these incentives must be appropriated in retained earnings reserve account in equity and cannot be distributed as dividends to shareholders. d) Income taxes - Settlement program (“REFIS”) Schedule of income taxes settlement Year ended December 31, 2022 2021 Current liabilities 371 324 Non-current liabilities 1,869 1,964 REFIS liabilities 2,240 2,288 SELIC rate 13.75 9.25 The balance is mainly related to the settlement program of claims regarding the collection of income tax and social contribution on equity gains of foreign subsidiaries and affiliates from 2003 to 2012. This amount bears SELIC interest rate (Special System for Settlement and Custody) and will be paid in monthly installments until October 2028. The impact of the SELIC over the liability is recorded under the Company’s financial results. e) Uncertain tax positions (“UTP”) The Company is engaged in administrative and judicial discussions with tax authorities in Brazil in relation to certain tax positions adopted by the Company for calculating income tax and social contribution on net income. The final determination is uncertain and depends on factors not controlled by the Company, such as changes in case law and changes in tax laws and regulations. The Company is subject to the assessment of income tax by local tax authorities in a range up to 10 years depending on jurisdiction where the Company operates. The amount under discussion with the tax authorities is US$ 3,659 3,122 564 527 Schedule of uncertain tax positions Year ended December 31, 2022 2021 UTPs not recorded on balance sheet (i) Transfer pricing over the exportation of ores to a foreign subsidiary 829 669 Expenses of interest on capital 1,154 981 Proceeding related to income tax paid abroad 439 399 Goodwill amortization 517 305 Payments to Renova Foundation 24 21 Other 696 747 Total not recorded on balance sheet 3,659 3,122 UTPs recorded on balance sheet Deduction of CSLL in Brazil 155 - Gain related to incidence of IRPJ and CSLL on SELIC rate in the repetition of undue payment - 34 Total recorded balance sheet 155 34 (i) Based on the assessment of its internal and external legal advisors, the Company believes that the tax treatment adopted for these matters will be accepted in decisions of the higher courts on last instance. Transfer pricing over the exportation of ores to a foreign subsidiary - The Company maintains the method of calculating the transfer price, as it considers it to be the most appropriate tax treatment for interpreting the rules in force and applicable to the subject and is discussing the aforementioned charges at the administrative level. The total amount in dispute is US$ 829 4,324 669 3,732 361 1,883 377 1,883 Expenses of interest on capital (“JCP”) - 1,154 6,021 981 5,477 134 699 125 699 Proceeding related to income tax paid abroad - 439 2,288 399 2,255 Goodwill amortization - One of the assessments is the goodwill generated in the privatization of the Company and recorded by Valepar, merged into the Parent Company in 2017. The Company is discussing the charges at the administrative level in the amount of US$ 517 2,698 305 1,703 61 320 57 320 223 1,162 Payments to Renova Foundation - The Company received a tax assessment notice for the collection of IRPJ and CSLL alleging that the expenses incurred with Renova Foundation were improperly deducted from the computation of the Company’s income tax, as they understand that these expenses are supposedly not necessary for Vale's operational activities. The total amount assessed is US$ 24 126 21 115 5 24 4 24 530 2,763 426 2,376 Deduction of CSLL in Brazil - Meanwhile, the Federal Supreme Court (“STF”) is judging two extraordinary appeals with impact to all taxpayers. These appeals are discussing how long a court decision related with a tax matter would remain valid if the STF had subsequently issued a contrary decision. Due to the developments of this matter in the STF during 2023 and based on the updated assessment of its legal advisors, the Company concluded that the tax treatment previously adopted will probably not be accepted by the tax authority and, therefore, it recognized a liability in the amount of US$155 (R$813 million) as “Taxes payable” for the year ended December 31, 2022. Gain related to incidence of IRPJ and CSLL on SELIC rate in the repetition of undue payment - 34 f) Recoverable and payable taxes Schedule of recoverable and payable taxes December 31, 2022 December 31, 2021 Current assets Non-current assets Current liabilities Current assets Non-current assets Current liabilities Value-added tax ("ICMS") 261 1 46 217 11 162 Brazilian federal contributions ("PIS and COFINS") 690 740 35 520 511 12 Income taxes 309 369 221 113 413 1,861 Financial compensation for the exploration of mineral resources ("CFEM") - - 54 - - 59 Other 12 - 114 12 - 83 Total 1,272 1,110 470 862 935 2,177 ICMS included in PIS and COFINS computation tax base - 60 313 146 The lawsuit that covers the triggering events that occurred between December 2001 and February 2012, resulted in the recognition of a gain in the amount of US$ 145 808 Accounting policy The Brazilian corporate tax law requires the taxation on the income generated from foreign subsidiaries and, therefore, income tax charge is calculated using the tax rate enacted at the end of the reporting period in Brazil. The effects of the income tax calculation in the consolidated financial statements are calculated by applying the differential between the Brazilian income tax rate and the local income tax rate of each jurisdiction where the Company’s subsidiaries operate and generate taxable income. Income taxes Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation and it establishes provisions, where appropriate, on the basis of amounts expected to be paid to the tax authorities. The liabilities related to uncertain tax positions are recorded only after determining, based on the position of its internal and external legal advisors, a more-likely-than-not probability that the uncertain tax positions will withstand challenge, if any, from taxing authorities. Deferred income taxes are recognized based on temporary differences between carrying amount and the tax basis of assets and liabilities as well as tax losses carryforward. However, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill. Deferred income tax is also not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that, at the time of the transaction, affects neither accounting nor taxable profit or loss. Deferred tax assets and liabilities are offset where there is a legally enforceable right to offset current tax assets and liabilities and where the deferred tax balances relate to the same taxation authority. The deferred tax assets arising from tax losses and temporary differences are not recognized when it is not probable that future taxable profit will be available against which temporary differences and/or tax losses can be utilized. Current and deferred tax is recognized in profit or loss, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this case, the tax is also recognized in other comprehensive income or directly in equity, respectively.

Joint arrangement investments are classified as either joint operations or joint ventures depending on the contractual rights and obligations of each investor. The joint operations are recorded in the financial statements to represent the Company’s contractual rights and obligations. Accordingly, the assets, liabilities, income and expenses related to the joint operation are recorded individually in the financial statements. Interests in joint ventures are accounted for using the equity method, after initially being recognized at cost. The Company investment in joint ventures includes the goodwill identified in the acquisition, net of any impairment loss. The Company interest in the profits or losses of its joint ventures is recognized in the income statement and participation in the changes in reserves is recognized in the Company's reserves. When the Company’s interest in the losses of an associate or joint venture is equal to or greater than the carrying amount of the investment, including any other receivables, the Company does not recognize additional losses, unless it has incurred obligations or made payments on behalf of the joint venture. In addition, the financial information of associates and joint ventures used to account for their impact in these financial statements may differ from the stand-alone financial statements of those entities due to adjustments to Vale's accounting policy and the length of the reporting periods. Cumulative translation adjustments Thus, the Company has determined as its accounting policy that a capital reduction in an investment in a foreign operation should be treated under the absolute value approach as described in ii) above. Therefore, the exchange differences recorded in equity are reclassified to the income statement in the same proportion as the reduction in the net investment held in the foreign operation. Critical accounting estimates and judgments Judgment is required in some circumstances to determine whether after considering all relevant factors, the Company has either control, joint control or significant influence over an entity. Significant influence includes situations of collective control. The Company holds the majority of the voting capital in five joint arrangements (Aliança Geração de Energia S.A., Aliança Norte Energia Participações S.A., Companhia Hispano-Brasileira de Pelotização, Companhia Ítalo-Brasileira de Pelotização and Companhia Nipo-Brasileira de Pelotização), but management has concluded that the Company does not have a sufficiently dominant voting interest to have the power to direct the activities of these entities. As a result, these entities are accounted under equity method due to shareholder’s agreements where relevant decisions are shared with other parties. Vale and Sumitomo Metal Mining Co. Ltd. (“SMM”) own a 44.3% and 15% equity interest in PT Vale Indonesia Tbk (“PTVI”), respectively, for a total of 59.3% interest in PTVI. Vale and SMM have a Shareholders' Agreement ("Block voting agreement"), establishing that SMM will follow Vale's guidelines in decision-making on financial and operational matters relevant to the management of PTVI and, therefore, the Company consolidates PTVI in its financial statements.

(“Vale Moçambique”) which was a company controlled by Vale, that had a non-controlling interest held by Mitsui & Co. Ltd. (“Mitsui”). Coal products are transported from the Moatize mine to the maritime terminal by the Nacala Logistics Corridor (“NLC”), which was a joint venture between Vale and Mitsui. The NLC’s main assets are the railways and port concessions located in Mozambique and Malawi. As part of the sustainable mining strategic agenda, the Company announced in 2021 its intention to divest from coal assets. To achieve this objective, it was necessary to carry out the corporate reorganization through the acquisition of the interests held by Mitsui in these assets, which, upon completion, allowed an agreement with Vulcan Minerals (“Vulcan”), for the sale of all coal assets. Following the signing of the agreement in December 2021, the Company started to treat coal as a discontinued operation. Below is a summary of the main events: Acquisition of non-controlling interest in Vale Moçambique On June 22, 2021, the Company acquired 15 331 1,666 95 Business combinations – NLC The Company also concluded the acquisition of NLC’s control on June 22, 2021, through the disbursement of US$ 2,517 50 Following the closing, the Company assessed the fair value of the acquired business, resulting in a loss of US$ 771 The fair values of identifiable assets acquired, and liabilities assumed as a result of the NLC’s acquisition were as follows: Fair value of assets and liabilities assumed June 22, 2021 Acquired assets Cash and cash equivalents 172 Inventory, recoverable tax, and other assets 423 Intangible 2,219 Property, plant, and equipment 1,363 Assumed liabilities (158) Net identifiable assets acquired 4,019 Fair value adjustments (i) (1,590) Total identifiable net assets at fair value 2,429 Pre-existing relation (Loans receivable from NLC) 859 Loss on pre-existing relation (771) Total identifiable net assets at fair value 2,517 Cash consideration 2,517 (-) Balances acquired Cash and cash equivalents 172 Net cash outflow 2,345 (i) Of this amount, US$ 441 791 Fair value adjustments Following the decision to divest from the coal segment, the Company initiated interactions with potential interested parties in acquiring these assets, and the negotiations that were underway at the time, resulted in the decision to provision in full the book value of these assets, mainly due to the difficulties to prove the expected productivity levels of metallurgical coal and thermal coal, due to the delays that occurred to implement the mining plan and the strategy for the plant to reach the ramp-up of the asset. The Company recorded the impact of US$ 2,511 Binding agreement with Vulcan Minerals (“Vulcan”) In December 2021, the Company entered into a binding agreement with Vulcan Resources (formerly Vulcan Minerals - “Vulcan”) for the sale of these assets. Under the sale agreement Vulcan has committed to pay the gross amount of US$ 270 10 In April 2022, the transaction was completed and the Company recorded a net income from discontinued operations of US$ 2,060 3,072 , 585 589 Net income and cash flows from discontinued operations Schedule of net income and cash flows from discontinued operations 2022 2021 2020 Net income from discontinued operations Net operating revenue 448 1,083 473 Cost of goods sold and services rendered (264) (1,386) (1,475) Operating expenses (13) (33) (43) Impairment and disposals of non-current assets, net (589) (3,282) (935) Operating loss (418) (3,618) (1,980) Cumulative translation adjustments (i) 3,072 Other financial results, net (7) 447 2 Derecognition of noncontrolling interest (585) Equity results in associates and joint ventures (26) (43) Net income (loss) before income taxes 2,062 (3,197) (2,021) Income taxes (2) 821 297 Net income (loss) from discontinued operations 2,060 (2,376) (1,724) Loss attributable to noncontrolling interests - (85) (347) Net income (loss) attributable to Vale's shareholders 2,060 (2,291) (1,377) (i) In 2021, the Company assessed that its Australian subsidiaries (part of the coal business), which were no longer operational, were considered "abandoned" under IAS 21 and, therefore, the Company recognized a gain related to the cumulative translation adjustments in the amount of US$424, which was reclassified to the net income as “Other financial items, net”. 2022 2021 2020 Cash flow from discontinued operations Operating activities Net income (loss) before income taxes 2,062 (3,197) (2,021) Adjustments: Equity results in associates and joint ventures - 26 43 Depreciation, amortization and depletion - 69 19 Impairment and disposals of non-current assets, net 589 3,282 935 Derecognition of noncontrolling interest 585 - - Financial results, net (3,065) (447) (2) Decrease in assets and liabilities (130) (49) (29) Net cash generated (used) by operating activities 41 (316) (1,055) Investing activities Additions to property, plant and equipment (38) (194) (203) Acquisition of NLC, net of cash - (2,345) - Disposal of coal, net of cash (65) - - Other - 70 74 Net cash used in investing activities (103) (2,469) (129) Financing activities Payments (11) (13) (15) Net cash used in financing activities (11) (13) (15) Net cash used by discontinued operations (73) (2,798) (1,199) b) Midwestern System – In April 2022, the Company entered into an agreement with J&F Mineração (“J&F”) for the sale of Vale’s iron ore, manganese and logistics assets in the Centro-Oeste System, through equity interests in Mineração Corumbaense Reunida S.A., Mineração Mato Grosso S.A., International Iron Company, Inc. and Transbarge Navegación S.A. The carrying amount of those assets were fully impaired in past years and the Company had a liability related to take-or-pay logistics contracts that were deemed onerous contracts under the Company’s business model for the Midwestern System. However, these offers received during the sale process of the assets represented an objective evidence of impairment reversal and the remeasurement of the existing provision, which led to a gain of US$ 1,121 214 916 9 In July 2022, the Company completed the transaction and received US$ 140 37 c) California Steel Industries (“CSI”) - In December 2021, the Company entered into a binding agreement with Nucor Corporation (“Nucor”) for the sale of its 50 437 292 142 150 d) Sale of Companhia Siderúrgica do Pecém (“CSP”) - In July 2022, the Company and the other shareholders of CSP signed a binding agreement with ArcelorMittal Brasil S.A. (“ArcelorMittal”) for the sale of CSP for approximately US$ 2,200 2,200 135 e) Manganese Operations in Minas Gerais - 40 25 Operations in Bahia - 11 10 10 76 f) Vale Nouvelle-Calédonie S.A.S. (“VNC ”) - In December 2020, the Company signed a binding put option agreement to sell its interest in VNC for an immaterial consideration to Prony Resources consortium. With the final agreement signed in March 2021, the Company recorded a loss in the amount of US$ 98 1,132 g) Vale Shipping Holding Pte. Ltd (“VSH”) - In October 2021, the Company approved the liquidation of VSH, its wholly-owned subsidiary that owned and operated the Company's vessels. In November 2021, VSH made a repayment of capital to VISA and, as a result, the Company recognized a gain of US$ 771 h) Option exercised in VLI shares - In December 2020, BNDES Participações S.A. (“BNDESPar”), fully exercised its option contained in the Call Option Contract for shares issued by VLI S.A. (“VLI”). In this contract, BNDESPar was granted call options on VLI shares held by Vale of up to 8 29.6 i) Biopalma da Amazônia S.A. Reflorestamento Indústria e Comércio (“Biopalma”)- In November 2020, the Company concluded the sale of Biopalma to Brasil Bio Fuels S.A. As a result of this transaction, a loss of US$125 was recognized in the income statement as “Impairment reversal (impairment and disposals) of non-current assets, net” for the year ended December 31, 2020. j) Henan Longyu Energy Resources Co., Ltd (“Longyu”) - In December 2019, the Company entered into an agreement to sell its 25% interest in Longyu, a company that operates two coal mines in China, for a total cash consideration of US$ 156 116 k) Divestment agreement in compliance with PT Vale Indonesia Tbk (“PTVI”) - Contract of Work - PTVI, a public company in Indonesia, has an agreement in place with the government of the Republic of Indonesia to operate its mining licenses, expiring in December 2025. According to the agreement, PTVI must meet certain requirements to extend the period of the mining licenses beyond 2025, including the commitment to have Indonesian participants in its shareholding structure. Following this commitment, in June 2020, the Company signed together with Sumitomo Metal Mining Co., Ltd. (“SMM”), an agreement for the sale of 20% (14.9% from Vale and 5.1% from SMM) of their aggregate stake in PTVI to PT Indonesia Asahan Aluminium (“PT Inalum”), an Indonesia state-owned enterprise. In October 2020, the Company concluded the transaction and received a cash consideration of US$278. This transaction with non-controlling interests resulted in a loss of US$179, which was recognized in equity for the year ended December 31,2020. At the closing of the transaction, Vale and SMM which have a stake of 44.3% and 15%, respectively, totaling a 59.3% interest in PTVI, signed a block voting agreement, in which SMM is required to follow Vale’s vote on relevant operational and financial decisions concerning PTVI. Therefore, the Company continues consolidating PTVI in its financial statements. l) The Mosaic Company (“Mosaic”) - The Company held 34.2 million common shares of Mosaic, the financial instrument was measured at fair value through other comprehensive income. Thus, changes in the fair value of this investment were accumulated in the Company's equity. In November 2021, the Company sold the entire investment of Mosaic shares for the total amount of US$1,259 and the amount US$522 was reclassified from other reserves to retained earnings reserve and, therefore, did not result in an impact on the income statement for the year ended December 31, 2021. m) Minerações Brasileiras Reunidas S.A. (“MBR”) – Until December 2019, the Company held 98.3% of MBR’s share capital. In 2020, the Company purchased the remaining interest in MBR for a net consideration of US$107, therefore, the Company holds 100% of MBR’s share capital as at December 31, 2022. n) Vale Oman Pelletizing Company LLC (“VOPC”) – In February 2023 (subsequent event), OQ Group exercised a call option to sell its 30% noncontrolling interest held in VOPC. Upon closing of the transaction, which is expected to take place in the second quarter of 2023, Vale will acquire the remaining interest for approximately US$130. This transaction should not result in a material impact, which will be recognized in the equity as “Acquisition and disposal of non-controlling interest”. With the acquisition, Vale will hold 100% of VOPC's share capital. Accounting policy Business combinations Identifiable assets acquired, and liabilities and contingent liabilities assumed in a business combination are, with limited exceptions, measured initially at their fair values at the acquisition date. The Company recognizes any non-controlling interest in the acquired entity on an acquisition-by-acquisition basis either at fair value or at the non-controlling interest’s proportionate share of the acquired entity’s net identifiable assets. Discontinued operations The result of discontinued operations is presented in a single amount in the income statement, including the results after income tax of these operations less any impairment loss. Cash flows attributable to operating, investing and financing activities of discontinued operations are disclosed in a separate note. When an operation is classified as a discontinued operation, the income statements of the prior periods are restated as if the operation had been discontinued since the beginning of the comparative period. Any noncontrolling interest relating to a group disposal held for sale is presented in the equity and is not reclassified in the statement of financial position.

Accounting policy Property, plant, and equipment Mineral properties developed internally are determined by (i) direct and indirect costs attributed to build the mining facilities, (ii) financial charges incurred during the construction period, (iii) depreciation of other fixed assets used during construction, (iv) estimated decommissioning and site restoration expenses, and (v) other capitalized expenditures during the development phase (phase when the project demonstrates its economic benefit to the Company, and the Company has ability and intention to complete the project). The depletion of mineral properties is determined based on the ratio between production and total proven and probable mineral reserves. Property, plant and equipment, other than mineral properties are depreciated using the straight-line method based on the estimated useful lives, from the date on which the assets become available for their intended use and are capitalized, except for land which is not depreciated. The estimated useful lives are as follows: Schedule of estimated useful lives of property, plant and equipment Useful life Buildings 3 50 Facilities 3 50 Equipment 3 40 Locomotives 12 25 Wagons 30 45 Railway equipment 5 37 Vessels 20 25 Other 2 50 The residual values and useful lives of assets are reviewed at the end of each reporting period and adjusted if necessary. Expenditures and stripping costs (i) Exploration and evaluation expenditures (ii) Expenditures on feasibility studies, new technologies and others research (iii) Maintenance costs (iv) Stripping Costs Post-production stripping costs are included in the cost of inventory, except when a new project is developed to permit access to a significant ore deposit. In such cases, the cost is capitalized as a non-current asset and is amortized during the extraction of the ore deposits, over the useful life of the ore deposits. Leases The Company does not recognize right-of-use assets and liabilities for leases with less than 12 months of lease term and/or leases of low-value assets. The payments associated to these leases are recognized as an expense on a straight-line basis over the lease term. The lease liability is initially measured at the present value of the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company’s incremental borrowing rate. Lease payments included in the measurement of the lease liability comprise: (i) fixed payments, including in-substance fixed payments; (ii) variable lease payments that depend on an index or a rate; and (iii) the exercise price under a purchase option or renewal option that are under the Company’s control and is reasonably certain to be exercised. The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in an index or rate. When the lease liability is remeasured, a corresponding adjustment is made to the carrying amount of the right-of-use asset or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero. Critical accounting estimates and judgments Mineral reserves The estimated volume of mineral reserves is used as basis for the calculation of depletion of the mineral properties, and also for the estimated useful life which is a major factor to quantify the provision for asset retirement obligation, environmental recovery of mines and impairment of long lived asset. Any changes to the estimates of the volume of mine reserves and the useful lives of assets may have a significant impact on the depreciation, depletion and amortization charges and assessments of impairment.

The recoverable amount of each CGU under the Company’s impairment test was assessed using the fair value less costs of disposal model (“FVLCD”), through discounted cash flow techniques, which is classified as “level 3” in the fair value hierarchy, taking into consideration offers and purchase agreements, if applicable. The cash flows were discounted by using a post-tax discount rate expressed in real terms, which represents an estimate of the rate that a market participant would apply having regard to the time value of money and the asset’s specific risk. The Company used its weighted average cost of capital (“WACC”) as a starting point for determining the discount rates, with appropriate adjustments for the risk profile of the countries in which the individual CGU operate. Climate change As outlined in note 2, the potential financial impacts on the Company of climate change and the transition to a low carbon economy have been considered in the assessment of the Company’s critical accounting estimates, which includes indicators of impairment, such as: (i) demand for the Company’s commodities decreasing, due to policy, regulatory (including carbon pricing mechanisms), legal, technological, market or societal responses to climate change; and (ii) physical impacts related to risks resulting from increased frequency or severity of extreme weather events, and those related to chronic risks resulting from longer-term changes in climate patterns. a) Impairment recorded on the sale of investments In the past few years, the Company has divested non-strategic assets, as detailed in note 16 to these financial statements. These transactions resulted in material impacts on Vale's results, which were recorded under "Impairment reversal (impairment and disposals) of non-current assets, net", as summarized below: · Midwestern system (note 16b) – As a result of the agreement for the sale of these assets to J&F, the Company recorded a gain in the amount of US$ 1,121 214 916 9 · Manganese (note 16e) – The Company has entered into agreements to sell its manganese assets, resulting in an impairment loss of US$ 10 35 76 · VNC (note 16f) – As a result of the sale of this asset to Prony Resources, the Company recognized an impairment loss of US$ 98 882 · Biopalma (note 16i)- In November 2020, the Company concluded the sale of this asset to Brasil Bio Fuels, resulting in an impairment loss of US$ 125 b) Impairment test for the goodwill and other intangibles (note 17) Goodwill allocated to iron ore and pellet operations Summary of impairment test for the goodwill 2022 2021 Carrying amount US$ 1,367 US$ 1,278 Impairment testing results The recoverable amount of the operating segments is higher than the carrying amount and, therefore, there is no impairment to be recognized.

A 80% reduction in processing and beneficiating iron ore volumes would, alone, result in estimated recoverable amount equal to the carrying value of this CGU. Accounting policy Impairment of non-financial assets FVLCD is generally determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset from a market participant’s perspective, including any expansion prospects. VIU model is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form. Value in use is determined by applying assumptions specific to the Company’s continued use and cannot take into account future development. These assumptions are different to those used in calculating fair value and consequently the VIU calculation is likely to give a different result to a FVLCD calculation. Assets that have an indefinite useful life and are not subject to amortization, such as goodwill, are tested annually for impairment. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (CGU). Goodwill is allocated to Cash Generating Units or Cash Generating Units groups that are expected to benefit from the business combinations in which the goodwill arose and are identified in accordance with the operating segment. Non-current assets (excluding goodwill) in which the Company recognized impairment in the past are reviewed whenever events or changes in circumstances indicate that the impairment may no longer be applicable. In such cases, an impairment reversal will be recognized. Onerous Contracts - Critical accounting estimates and judgments Significant judgements, estimates and assumptions are required to determine whether an impairment trigger has occurred and to prepare the Company’s cash flows. Management uses the budgets approved as a starting point and key assumptions are, but not limited to: (i) mineral reserves and mineral resources measured by internal experts; (ii) costs and investments based on the best estimate of projects as supported by past performance; (iii) sale prices consistent with projections available in reports published by industry considering the market price when appropriate; (iv) the useful life of each cash-generating unit (ratio between production and mineral reserves); and (v) discount rates that reflect specific risks relating to the relevant assets in each cash-generating unit. These assumptions are susceptible to risks and uncertainties and may change the Company’s projection and, therefore, may affect the recoverable value of assets.

Financial And Capital Risk Management
Financial and capital risk management	Financial and capital risk management The Company is exposed to several financial and capital risk factors that may impact its performance and equity position. The evaluation of the exposure to financial and capital risks is performed periodically to support decision making process regarding the risk management strategy. The Company's policy aims at establishing a capital structure that will ensure the continuity of our business in the long term. Within this perspective, the Company has been able to deliver value to shareholders through dividend payments and capital gain, and at the same time maintain a debt profile suitable for its activities, with an amortization well distributed over the years, thus avoiding a concentration in one specific period. The Board of Directors establishes and supervises the management of financial risks with the support of the Capital Allocation and Project Advisory Committee, which ensures that Company's financial activities are governed by appropriate policies and procedures and that financial risks are identified, measured and managed in accordance with the Company's policies and objectives. The Company has developed its strategy through an integrated view of the risks to which it is exposed, considering not only the risk, generated by variables traded in the financial market (market risk) and the liquidity risk, but also the risk arising from obligations assumed by third parties to the Company (credit risk), among others. The Company uses derivative financial instruments to protect its exposure to these market risks arising from operating, financing, and investment activities. The financial instruments portfolio is reassessed monthly, allowing the monitoring of financial results and their impact on cash flow. The Company applies hedge accounting to its net investment in foreign operation and nickel and palladium revenue programs. The Company does not have any derivatives increasing financial leverage beyond the nominal amount of its contracts. The Company contracts derivatives primarily for mitigation of market risks. Risks Origin of the exposure Management Market Risk - Exchange Rate Financial instruments and other financial liabilities that are not denominated in US$ Swap and forward operations Market risk - Interest rate Loans and financing indexed to different interest rates including, but not limited to, LIBOR and CDI Swap operations Market risk - Product and input prices Volatility of commodity and input prices Forward operations and option contracts Credit Risk Receivables, derivative transactions, guarantees, advances to suppliers and financial investments Portfolio diversification and policies for monitoring counterparty solvency and liquidity indicators Liquidity risk Contractual or assumed obligations Availability of revolving credit lines a) Method and techniques for valuation of derivatives The risk of the derivatives instruments is measured using the delta-Normal parametric approach and considers that the future distribution of the risk factors and its correlations tends to present the same statistic properties verified in the historical data. The value at risk estimate considers a 95% confidence level for a one-business daytime horizon. The derivative financial instruments were evaluated using the curves and market prices that impact each instrument on the calculation dates. For the pricing options, the Company generally uses the Black & Scholes model. In this model, the fair value of the derivative is obtained as a function of the volatility and price of the underlying asset, the exercise price of the option, the risk-free interest rate and the term to maturity of the option. In the case of options where the result is a function of the average price of the underlying asset in a certain period of the option’s life, known as Asian options, the Company uses the Turnbull & Wakeman model. In this model, in addition to the factors that influence the option price in the Black & Scholes model, the average price formation period is considered. In the case of swaps, both the present value of the paying and receiving amounts are estimated by discounting the cash flows by the interest rates in the corresponding currencies. The fair value is obtained by the difference between the present value of the paying and receiving amounts of the swap in the reference currency. In the case of swaps linked to Brazilian long-term interest rate (“TJLP”), the fair value calculation considers the current TJLP, i.e., projections of future cash flows in reais are made considering the last TJLP disclosed. Forward and future contracts are priced using the futures curves of the respective underlying assets. These curves are usually obtained from the exchanges where these assets are traded, such as the London Metals Exchange (“LME”), the Commodities Exchange (“COMEX”) or other market price providers. When there is no price for the desired maturity, the Company uses interpolations between the available maturities. a.i) Effects of derivatives on the balance sheet Schedule of derivatives effects on statement of financial position December 31, 2022 December 31, 2021 Reference Assets Liabilities Assets Liabilities Foreign exchange and interest rate risk CDI & TJLP vs. US$ fixed and floating rate swap 20(b.i) 11 144 - 591 IPCA swap 20(b.i) - 63 41 119 Dollar swap and forward transactions 20(b.i) 407 7 29 95 LIBOR swap 20(b.ii) 7 - 12 1 425 214 82 806 Commodities price risk Gasoil, Brent and freight 20(c) 78 56 8 2 Energy Transition Materials 20(d) 35 1 28 27 113 57 36 29 Other 20(d) - 5 13 - Total 538 276 131 835 a.ii) Net exposure Reference December 31, 2022 December 31, 2021 Foreign exchange and interest rate risk CDI & TJLP vs. US$ fixed and floating rate swap 20(b.i) (133) (591) IPCA swap 20(b.i) (63) (78) Dollar swap and forward transactions 20(b.i) 400 (66) LIBOR swap (i) 20(b.ii) 7 11 211 (724) Commodities price risk Gasoil, Brent and freight 20(c) 22 6 Energy Transition Materials 20(d) 34 1 56 7 Other 20(d) (5) 13 Total 262 (704) (i) In March 2021, the UK Financial Conduct Authority (“FCA”), the financial regulator in the United Kingdom, announced the discontinuation of the LIBOR rate for all terms in pounds, euros, Swiss francs, yen and for terms of one week and two months in dollars at the end of December 2021 and the other terms at the end of June 2023. Vale is in negotiations with some financial institutions to replace the reference interest rate of its financial contracts from LIBOR to Secured Overnight Financing Rate ("SOFR"), with spread adjustments to match the transaction costs.

While most of our product prices are indexed to U.S. dollars, most of our costs, expenses and investments are indexed to currencies other than the U.S. dollar, principally the Brazilian real and the Canadian dollar. The Company implements hedge transactions to protect its cash flow against the market risks that arises from its debt obligations and other liabilities – mainly currency volatility. The hedges cover most of the debt denominated in Brazilian real. The Company uses swap and forward transactions to convert debt and financial obligations linked to Brazilian real into U.S. dollar, with volumes, flows and settlement dates similar to those of the debt instruments and financial obligations - or sometimes lower, subject to market liquidity conditions. Hedging instruments with shorter tenors are renegotiated through time, so that their final maturity matches - or becomes closer - to the debt and financial obligations final maturity. At each settlement date, the results of the swap and forward transactions partially offset the impact of the foreign exchange rate in the Company’s obligations, contributing to stabilize the cash disbursements in U.S. dollar. b.i) Protection programs for the R$ denominated debt instruments and other liabilities To reduce cash flow volatility, swap and forward transactions were implemented to convert into US$ the cash flows from certain liabilities denominated in R$ with interest rates linked mainly to Brazilian Interbank Interest rate (“CDI”), TJLP and consumer price index (“IPCA”).

The US Dollar floating rate debt in the portfolio consists mainly of loans including export pre-payments, commercial banks and multilateral organizations loans. In general, such debt instruments are indexed to the LIBOR in US dollar. To reduce the cash flow volatility, swap transactions were implemented to convert interest rate indexed to LIBOR from certain debt instruments into fixed interest rate. In those swaps, the Company received floating rates and paid fixed rates in US$. In August 2022, this swap operations were terminated and Vale is currently in negotiations with some financial institutions to replace the reference interest rate of its financial contracts from LIBOR to SOFR, with spread adjustments to match the transaction costs. However, the Company has maintained its swap strategy for the remaining $150 of debt indexed to LIBOR.

Cash flow hedge (Palladium) - The contracts are traded on the London Metal Exchange or over-the-counter market and the hedged item's P&L is offset by the hedged item’s P&L due to Palladium price variation. In 2022, this program was concluded. f) Credit risk management The Company is exposed to credit risk that arises from trade receivables, derivative transactions, guarantees, down payment for suppliers and cash investments. The credit risk management process provides a framework for assessing and managing counterparties’ credit risk and for maintaining our portfolio risk at an acceptable level. For the commercial credit exposure, which arises from sales to final customers, the risk management area, in accordance with the current delegation level, approves or requests the approval of credit risk limits for each counterparty. Vale attributes an internal credit risk rating for each counterparty using its own quantitative methodology for credit risk analysis, which is based on market prices, external credit ratings and financial information of the counterparty, as well as qualitative information regarding the counterparty’s strategic position and history of commercial relations. Based on the counterparty’s credit risk, risk mitigation strategies may be used to manage the Company’s credit risk. The main credit risk mitigation strategies include non-recourse sale of receivables, insurance instruments, letters of credit, corporate and bank guarantees, mortgages, among others. f.i) Accounts receivable portfolio Vale has a diversified accounts receivable portfolio from a geographical standpoint, with Asia, Europe and Brazil as the regions with more significant exposures. According to each region, different guarantees can be used to enhance the credit quality of the receivables. Historically, the expected credit loss on the Company’s accounts receivable portfolio is immaterial (note 11). f.ii) Financial instruments, except for accounts receivable To manage the credit exposure arising from cash investments and derivative instruments, credit limits are approved to each counterparty with whom the Company has credit exposure. Furthermore, the Company controls the portfolio diversification and monitors different indicators of solvency and liquidity of the different counterparties that were approved for trading. The carrying amount of the financial assets that represent the exposure to credit risk is presented below: Schedule of carrying amount of the financial assets that represent the exposure to credit risk Notes December 31, 2022 December 31, 2021 Cash and cash equivalents 23 4,736 11,721 Short-term investments 23 61 184 Restricted cash 77 117 Judicial deposits 28 1,215 1,220 Derivative financial instruments 538 131 Investments in equity securities 14 7 6 6,634 13,379 f.iii) Financial counterparties’ ratings The transactions of derivative instruments, cash and cash equivalents as well as short-term investments are held with financial institutions whose exposure limits are periodically reviewed and approved by the delegated authority. The financial institutions credit risk is performed through a methodology that considers, among other information, ratings provided by international rating agencies. The table below presents the ratings in foreign currency as published by Moody’s regarding the main financial institutions used by the Company to contract derivative instruments, cash and cash equivalents transaction.

The available revolving credit facilities are intended to assist short term liquidity management and to enable more efficiency in cash management and were provided by a syndicate of several global commercial banks. The Company has two revolving credit facilities, in the amount of US$ 5,000 3,000 2,000 Accounting policy The Company uses financial instruments to hedge its exposure to certain market risks arising from operational, financing and investing activities. Derivatives are included within financial assets or liabilities at fair value through profit or loss unless they are designated as effective hedging instruments (hedge accounting). Derivative financial instruments At the beginning of the hedge operations, the Company documents the type of hedge, the relation between the hedging instrument and hedged items, its risk management objective and strategy for undertaking hedge operations. The Company also documents, both at hedge inception and on an ongoing basis that the hedge is expected to continue to be highly effective. The Company has elected to adopt the new general hedge accounting model in IFRS 9 and designates certain derivatives as either: Cash flow hedge - The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in equity within "Unrealized fair value gain (losses)". The gain or loss relating to the ineffective portion is recognized immediately in the income statement. When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognized in profit or loss when the transaction is recognized in the income statement. Net investment hedge - Hedges of net investments in foreign operations are accounted for similarly to cash flow hedges. Any gain or loss on the hedging instrument relating to the effective portion of the hedge is recognized in equity within "Cumulative translation adjustments". The gain or loss relating to the ineffective portion is recognized immediately in the income statement. Gains and losses accumulated in equity are included in the statement of income when the foreign operation is partially or fully disposed of or sold. Derivatives at fair value through profit or loss - Certain derivative instruments do not qualify for hedge accounting. Changes in the fair value of any of these derivative instruments are recognized immediately in the income statement. Critical accounting estimates and judgments The fair values of financial instruments that are not traded in active markets are determined using valuation techniques. Vale uses its own judgment to choose between the various methods. Assumptions are based on the market conditions, at the end of the year. An analysis of the impact if actual results are different from management's estimates is present under “Sensitivity analysis of derivative financial instruments”.

All financial liabilities are initially measured at fair value, net of transaction costs incurred and are subsequently carried at amortized cost and updated using the effective interest rate method. Excepts for Participative shareholders’ debentures and Derivative financial instruments that are measured at FVTPL. Fair value hierarchy - Level 1: The fair value of financial instruments traded in active markets (e.g. derivatives and publicly traded shares) is based on quoted market prices at the end of the financial statements period. Level 2: The fair value of financial instruments that are not traded in an active market (e.g. over the counter derivatives) is determined using valuation techniques that maximize the use of observable market data. If all significant data required for the fair value of an instrument are observable, the instrument is included in level 2. Level 3: If one or more of the significant data are not based on observable market data, the instrument is included in level 3. The fair value of derivatives classified as level 3 is estimated using discounted cash flows and option valuation models with unobservable inputs of discount rates, stock prices and commodity prices.

Brumadinho Dam Failure
Brumadinho dam failure	Brumadinho dam failure In January 2019, a tailings dam (“Dam I”) experienced a failure at the Córrego do Feijão mine, in the city of Brumadinho, state of Minas Gerais. The failure released a flow of tailings debris, destroying some of Vale’s facilities, affecting local communities and disturbing the environment. The tailings released have caused an impact of around 315 km in extension, reaching the nearby Paraopeba River. The dam failure in Brumadinho (“event”) resulted in 270 fatalities or presumed fatalities, including 3 victims still missing, and caused extensive property and environmental damage in the region. On February 4, 2021, the Company entered into a Judicial Settlement for Integral Reparation (“Global Settlement”), which was under negotiations since 2019, with the State of Minas Gerais, the Public Defender of the State of Minas Gerais and the Federal and the State of Minas Gerais Public Prosecutors Offices, to repair the environmental and social damage resulting from the Dam I rupture. The Global Settlement was ratified by the Minas Gerais State Court on February 4, 2021, and the res judicata was drawn up on April 7, 2021. As a result of the dam failure, the Company has been recognizing provisions to meet its assumed obligations, including indemnification to those affected by the event, remediation of the impacted areas and compensation to the society, as shown below: Summary of changes in provisions to meet its assumed obligations, including de-characterization of the dams December 31, 2021 Operating expense Monetary and present value adjustments Disbursements Translation adjustment December 31, 2022 Global Settlement for Brumadinho Payment obligations 1,427 - 113 (795) 137 882 Provision for socio-economic reparation and others 852 - 3 (72) 84 867 Provision for social and environmental reparation 705 - 59 (37) 50 777 2,984 - 175 (904) 271 2,526 Commitments Tailings containment and geotechnical safety 318 303 (1) (80) 19 559 Individual indemnification 115 - (4) (74) 8 45 Other commitments 120 97 (5) (35) 5 182 553 400 (10) (189) 32 786 Liability 3,537 400 165 (1,093) 303 3,312 Current liability 1,156 944 Non-current liability 2,381 2,368 Liability 3,537 3,312 Discount rate in nominal terms 8.08 9.08 (i) The Company has incurred expenses, which have been recognized straight to the income statement, in relation to tailings management, humanitarian assistance, payroll, legal services, water supply, among others. In 2022, the Company incurred expenses in the amount of US$ 620 650 a) Global Settlement for Brumadinho The Global settlement includes: (i) payment obligations, of which the funds will be used directly by the State of Minas Gerais and Institutions of Justice for socio-economic and socio-environmental compensation projects; (ii) socioeconomic projects in Brumadinho and other municipalities; and (iii) compensation of the environmental damage caused by the dam failure. These obligations are projected for an average period of 5 years. For the measures (i) and (ii), the agreement specifies an amount for each project and changes in the original budget and deadlines may have an impact in the provision. In addition, the execution of the environmental recovery actions has no cap limit despite having been estimated in the Global Settlement due to the Company's legal obligation to fully repair the environmental damage caused by the dam failure. The expenses related to these obligations are deducted from the income tax calculation, in accordance with the Brazilian tax regulation, which is subject to periodic inspection by the competent authorities. Therefore, although Vale is monitoring this provision, the amount recorded could materially change depending on several factors that are not under the Company’s control. b) Provision for individual indemnification and other commitments The Company is also working to ensure geotechnical safety of the remaining structures at the Córrego do Feijão mine, in Brumadinho, and the removal and proper disposal of the tailings of Dam I, including dredging part of the released material and de-sanding from the channel of the river Paraopeba. For the individual indemnification, Vale and the Public Defendants of the State of Minas Gerais formalized an agreement on April 5, 2019, under which those affected by the Brumadinho’s dam failure may join an individual or family group out-of-Court settlement agreements for the indemnification of material, economic and moral damages. This agreement establishes the basis for a wide range of indemnification payments, which were defined according to the best practices and case law of Brazilian Courts, following rules and principles of the United Nations. c) Contingencies and other legal matters Public civil actions brought by the State of Minas Gerais and state public prosecutors for damages resulting from the failure of Dam I The Company is party to public civil actions brought by the State of Minas Gerais and justice institutions, claiming compensation for socioeconomic and socio-environmental damages resulting from the dam failure and seeking a broad range of preliminary injunctions ordering Vale to execute specific remediation and reparation actions. As a result of the Global Settlement, settled in February 2021, the requests for the reparation of socio-environmental and socioeconomic damages caused by the dam failure were substantially resolved. Indemnifications for individual damages was excluded from the Global Settlement, and the Term of Commitment signed with the Public Defendants of the State of Minas Gerais was ratified, whose parameters are utilized as a basis for the settlement of individual agreements. In the same year of 2021, the fulfilment of the Global Settlement was initiated, by Vale and other parties. Collective Labor Civil Action In 2021, public civil actions were filed with Labor Court of Betim in the State of Minas Gerais, by a workers' unions claiming the compensation for death damages to own and outsourced employees, who died as a result of the failure of Dam I. Initial decisions sentenced Vale to pay US$192 thousand (R$1 million) per fatality. Vale is defending itself in the lawsuits and considers that the likelihood of loss is possible. U.S. Securities class action suit Vale is defending itself against a class action brought before a Federal Court in New York and filed by holders of securities - American Depositary Receipts ("ADRs") - issued by Vale. Following the decision of the Court, in May 2020, that denied the Motion to Dismiss presented by the Company, the Discovery phase has started and is expected to be concluded in 2023. On November 24, 2021, a new complaint was filed before the same Court by eight Plaintiffs, all investment funds, as an “opt-out” litigation from the class action already pending in the Eastern District of New York court, asserting virtually the same allegations in the main class action. The likelihood of loss of these proceedings is considered possible. However, considering the initial phase of this class action, it is not yet possible to reliably estimate the amount of a potential loss. The amount of damages sought in these claims is unspecified. Arbitration proceedings filed by minority shareholders and a class association In Brazil, Vale is name as a defendant in (i) one arbitration filed by 385 minority shareholders, (ii) two arbitrations filed by a class association allegedly representing all Vale’s non-controlling shareholders, and (iii) three arbitrations filed by foreign investment funds. In the six proceedings, the claimants argue that Vale was aware of the risks associated with the dam and failed to disclose it to its shareholders. Based on such argument, they claim compensation for losses caused by the decrease in share price. The expectation of loss is classified as possible for the six procedures and, considering the initial phase, it is not possible at this time to reliably estimate the amount of a possible loss. In one of the proceedings filed by foreign funds, the Claimants initially estimated the amount of the alleged losses would be approximately US$ 345 1,800 747 3,900 Securities and Exchange Commission (“SEC”) and investigations conducted by the CVM On April 28, 2022, SEC filed a suit against Vale alleging violations of U.S. securities laws due to Vale’s disclosures about its dam safety management, including the dam in Brumadinho. The SEC is seeking the imposition of civil monetary penalties, disgorgement and other relief within the SEC’s authority in a lawsuit filed in a federal court. Vale believes that its disclosures did not violate U.S. law and is contesting such allegations. On September 29, 2022, Vale served the SEC with its motion to dismiss the claim. The SEC’s deadline to serve Vale with its Opposition to the motion to dismiss is currently ongoing. CVM is also conducting investigations relating to Vale's disclosure of relevant information to shareholders, investors and the market in general, especially regarding the conditions and management of Vale's dams. The likelihood of loss of this proceeding is classified as possible and it is not yet possible to reliably estimate the amount of a potential loss to the Company. Criminal proceedings and investigations In January 2020, the State Prosecutors of Minas Gerais (“MPMG”) filed criminal charges against 16 individuals (including former executive officers of Vale and former employees) for a number of potential crimes, including homicide, and against Vale S.A. for alleged environmental crimes. In November 2021, the Brazilian Federal Police concluded the investigation on potential criminal responsibility related with the Brumadinho dam failure and the final report sent to the Federal Public Prosecutors (“MPF”). In January 2023 (subsequent event), after the Federal Supreme Court recognized the competence of the Federal Court, the MPF ratified the complaint presented by MPMG, which was received by the competent authority. The MPF and the Brazilian Federal Police conducted a separate investigation into the causes of the dam failure in Brumadinho, which may result in new criminal proceedings. Vale is defending itself against the criminal claims and is not possible to estimate when a decision will be issued. The likelihood of a financial loss to the Company is classified as possible and it is not yet possible to reliably estimate the amount of a potential loss to Vale. Decision of the Brazilian Office of the Comptroller General of the Union (“CGU”) In October 2020, the CGU notified the Company about an administrative proceeding prosecution based on the same allegations mentioned above under the Brazilian Law 12,846/2013 in connection with inspection and monitoring activities related to the Brumadinho dam. In August 2022, the CGU concluded that Vale has failed to present reliable information to the Brazilian National Mining Agency (“ANM”), as once a positive stability condition statement (“DCE”) was issued for the Dam I, where it should be negative in the view of the CGU. Thus, even recognizing the non-existence of corruption acts or practices, the CGU fined Vale US$16 (R$86 million), which is the minimum amount established by law, i.e., the CGU recognizes the non-involvement or tolerance of the Company’s top management. Vale has submitted a request for reconsideration and considers the likelihood of loss for this amount is possible. d) Insurance The Company is negotiating with insurers the payment of indemnification under its civil liability and Directors and Officers Liability Insurance. However, these negotiations are still in progress, therefore any payment of insurance proceeds will depend on the coverage definitions under these policies and assessment of the amount of loss. Due to uncertainties, no indemnification related to these insurers was recognized in these financial statements. Critical accounting estimates and judgments The provision for social, economic and environmental Thus, the amounts actually incurred by the Company may differ from the amounts currently provisioned, due to the confirmation of the assumptions used and which depend on several factors, some of which are not under the Company's control. These changes could result in a material impact on the amount of the provision in future periods. At each presentation date of its financial statements, the Company will reassess the main assumptions used in the preparation of projected cash flows and will adjust the provision, when applicable.

Liabilities Related To Associates And Joint Ventures
Liabilities related to associates and joint ventures	Liabilities related to associates and joint ventures a) Samarco dam failure In November 2015, the Fundão tailings dam owned by Samarco Mineração S.A. (“Samarco”) experienced a failure, releasing mine tailings downstream, flooding certain communities and impacting communities and the environment along the Doce River. The dam failure resulted in 19 fatalities and caused property and environmental damage to the affected areas. Samarco is a joint venture equally owned by Vale S.A. and BHP Billiton Brasil Ltda. (‘‘BHPB’’). In 2016, Vale, Samarco and BHPB, entered into a Framework Agreement with the Federal Government of Brazil, the states of Espírito Santo and Minas Gerais and certain other public authorities to establish the Renova Foundation that is developing and executing environmental and socio-economic programs to remediate and provide compensation for damage caused by the Samarco dam failure. In June 2018, Samarco, Vale and BHPB entered into a comprehensive agreement with the offices of the federal and state (Minas Gerais and Espírito Santo) prosecutors, public defenders and attorney general, among other parties (“TacGov Agreement”), improving the governance mechanism of Renova Foundation and establishing, among other things, a process for potential revisions to the remediation programs under the Framework Agreement. Under the Framework Agreement, Samarco has primary responsibility for funding Renova Foundation’s annual calendar year budget for the duration of the Framework Agreement. However, to the extent that Samarco does not meet its funding obligations, Vale and BHPB have secondary funding obligations under the Framework Agreement in proportion to their 50 per cent shareholding in Samarco. Samarco began to gradually recommence operations in December 2020, however, there remains significant uncertainty regarding Samarco’s long-term cash flow generation. b) Changes on the provisions in the year Schedule of changes on the provisions related to samarco dam failure December 31, 2021 Income statement Monetary and present value adjustments Disbursements Translation adjustments December 31, 2022 Renova Foundation reparation and compensation programs 2,910 110 243 (338) 199 3,124 De-characterization of the Germano dam 202 (21) 1 - 15 197 Liabilities 3,112 89 244 (338) 214 3,321 Current liabilities 1,785 1,911 Non-current liabilities 1,327 1,410 Liabilities 3,112 3,321 Discount rate in nominal terms 5.48 8.79 6.20 9.51 c) Renova Foundation In 2022 new court decisions were issued on individual compensation for the residents of the towns impacted by the dam failure, impacting the provisioning related to the Renova Foundation. These decisions mainly altered and expanded the number of types of damage, categories and amounts that can be compensated to the impacted towns. The increase in the provision is substantially a result of these judicial decisions. d) Germano Dam In addition to the Fundão tailings dam, Samarco owns the Germano dam, which was also built under the upstream method and has been inactive since the Fundão dam failure. Due to the safety requirements set by the Brazilian National Mining Agency (“ANM”), Samarco prepared a project for the de-characterization of this dam, resulting in a provision for the de-characterization of the Germano tailings dam. e) Samarco’s working capital In addition to the provision, Vale made available the amount of US$ 21 f) Insurance Since the Fundão dam failure, the Company has been negotiating with insurers the indemnification payments based on its general liability policies. In 2021, the Company received payments in the amount of US$33, which was recorded as a gain in the income statement as “Equity results and other results in associates and joint ventures”. The Company did not receive any further insurance in 2022 and does not expect to receive any material amounts in the future. g) Judicial recovery of Samarco In April 2021, Samarco filed for Judicial Reorganization (“JR”) with the Courts of Minas Gerais to renegotiate its debt, which is held by bondholders abroad. The purpose of JR is to restructure Samarco’s debts and establish an independent and sustainable financial position, allowing Samarco to keep working to resume its operations safely and to fulfill its obligations related to the Renova Foundation. In addition, the ongoing discussions in the context of the JR may lead to the loss of deductibility of part of the expenses incurred with the Renova Foundation and of the deferred taxes over the total provision, depending on the method determined for restructuring Samarco's debts. As at December 31, 2022, the exposure is US$ 1,620 571 The Company is working with the perspective that the mechanisms resulting from the JR will continue allowing the deductibility of these expenses. However, future decisions resulting from the negotiations regarding Samarco's capital structure, which are not under Vale's control, could materially change the deferred tax recognized by the Company. h) Contingencies related to Samarco accident These proceedings include public civil actions brought by Brazilian authorities and multiple proceedings involving claims for significant amounts of damages and remediation measures. The Framework Agreements represents a model for the settlement of the public civil action brought by the MPF and other related proceedings. There are also putative securities class actions in the USA against Vale and some of its current and former officers and a criminal proceeding in Brazil. The main updates regarding the lawsuits in the year were as follows: Public Civil Action filed by the Federal Government and others and public civil action filed by the Federal Public Ministry ("MPF") Vale is a defendant in several legal proceedings brought by governmental authorities and civil associations claiming socioenvironmental and socioeconomic damages and a number of specific remediation measures as a result of the Samarco’s Fundão dam failure, including a claim brought by the Federal Public Prosecution Office in 2016 seeking US$29 billion (the effect for Vale would be 50% of this amount), which has been suspended from the date of ratification of the TacGov Agreement. However, as pre-requisites established in the TacGov Agreement, for renegotiation of the Framework Agreement were not implemented during the two-year period ended September 30, 2020, the Brazilian Federal and State prosecutors and public defenders filed a request for the immediate resumption of the US$ 29 Therefore, Vale, Samarco, BHPB and Federal and State prosecutors have been engaging in negotiations to seek a definitive settlement of the obligations under the Framework Agreement and the US$29 billion Federal Public Prosecution Office claim. The goal in signing a potential agreement is to provide a stable framework for the execution of reparation and compensation programs. The potential agreement is still uncertain as it is subject to conclusion of the negotiations and approval by the Company, relevant authorities and intervenient parties. The estimate of the economic impact of a potential agreement will depend mainly on (i) a detailed assessment of the estimates of the amounts to be spent on the reparation and compensation projects being discussed, (ii) an analysis of the detailed scope of such projects to determine their overlap with the initiatives and amounts already provisioned; and (iii) the timing of the execution of projects and disbursements, which will impact the present value of the obligations. Therefore, until any revisions to the Programs are agreed, Renova Foundation will continue to implement the Programs in accordance with the terms of the Framework Agreement and the TacGov Agreement, for which the expected costs are reflected in the Company’s provision. Criminal proceedings In September 2019, the federal court dismissed all criminal charges against Vale representatives relating to the first group of charges, which concerns the results of the Fundão dam failure, remaining only the legal entity in the passive pole. The second group of charges against Vale S.A. and one of the Company’s employees, which concerns the accusation of alleged crimes committed against the Environmental Public Administration, remained unchanged. The Company cannot estimate when a final decision on the case will be issued. The likelihood of a financial loss to the Company is classified as possible and it is not yet possible to reliably estimate the amount of a potential loss to Vale. United Kingdom contribution claim As a result of the rupture of Samarco’s Fundão dam failure, BHP Group Ltd (“BHP”) was named as defendant in group action claims for damages filed in the courts of England and Wales (The “UK Claim”). The UK Claim includes only BHP and was filed on behalf of certain individuals and municipalities in Brazil only against BHP, for the allegedly damages caused by the Fundão dam failure. In December 2022, BHP filed a contribution claim against Vale, requesting the Company to be responsible for the indemnification payments in the proportion to its interest held in Samarco. The Company believes that it is not subject to the jurisdiction of the English Court and it does not have any contractual obligation in relation to this matter, therefore, the Company has assessed the risk of loss as remote. i) Summarized financial information The summarized financial information of Samarco are as follows. The stand-alone financial statements of Samarco may differ from the financial information reported herein, which is prepared considering Vale’s accounting policies. Summarized financial information of samarco December 31, 2022 December 31, 2021 Current assets 454 561 Non-current assets 2,748 2,921 Total assets 3,202 3,482 Current liabilities 10,808 10,902 Non-current liabilities 7,401 7,040 Total liabilities 18,209 17,942 Negative reserves (15,007) (14,460) Net income (loss) for the year ended 11 (3,208) Following the recent decision of the STF, as detailed in note 8(e), the Company expects that Samarco will also recognize a material liability in its financial statements and, therefore, it may impact Samarco’s ability to meet its cash obligations in the future. However, as described in its accounting policy, the Company does not have an obligation to provide funding to Samarco and it did not record a provision accordingly. Moreover, the Company already has a provision related to Renova Foundation and this matter does not have any impact in the existing provision recorded by Vale as at December 31, 2022. Critical accounting estimates and judgments Under Brazilian legislation and the terms of the joint venture agreement The provision related to Renova Foundation requires the use of assumptions that may be mainly affected by: (i) changes in scope of work required under the Framework Agreement as a result of further technical analysis and the ongoing negotiations with the Federal Prosecution Office, (ii) activity level of Samarco´s operations; (iii) updates of the discount rate; and (iv) resolution of existing and potential legal claims. Moreover, the main critical assumptions and estimates applied in the Germano dam provision considers, among others: (i) volume of the waste to be removed based on historical data available and interpretation of the enacted laws and regulations; (ii) location availability for the tailings disposal; and (iii) acceptance by the authorities of the proposed engineering methods and solution. As a result, future expenditures may differ from the amounts currently provided and changes to key assumptions could result in a material impact to the amount of the provision in future reporting periods. At each reporting period, the Company reassess the key assumptions used by Samarco in the preparation of the projected cash flows and adjust the provision, if required.

Provision for de-characterizati

Provision For De-characterization Of Dam Structures And Asset Retirement Obligations
Provision for de-characterization of dam structures and asset retirement obligations	Provision for de-characterization of dam structures and asset retirement obligations The Company is subject to local laws and regulations, that requires the decommissioning of the assets and mine sites that Vale operates at the end of their useful lives, therefore, expenses for demobilization occur predominantly after the end of operational activities. Depending on the geotechnical characteristics of the structures, the Company is required to de-characterize the structures, as shown in item a) below. Laws and regulations related to dam safety In September 2020, the Federal Government enacted Law no. 14,066, which modified the National Dam Safety Policy (Law no. 12,334/2020), reinforcing the prohibition of constructing and raising upstream dams in Brazil. The law also requires companies to de-characterize the structures built using the upstream method by 2022, or by a later date if it is proven that the de-characterization is not technically feasible by 2022. As made available to competent bodies, a substantial part of the Company's de-characterization projects will be completed in a period exceeding the date established in the legislation due to the characteristics and safety levels of the Company's geotechnical structures. Thus, in February 2022, the Company filed with the relevant bodies a request for an extension to perform the projects and, as a result, signed a Term of Commitment establishing legal and technical certainty for the process of de-characterization of the upstream dams, considering that the deadline defined was technically unfeasible, especially due to the necessary actions to increase safety during the works. With the signing of the agreement, the Company recorded an additional provision of US$37 (R$192 million) to make investments in social and environmental projects over a period of 8 years. In December 2022, the Federal Government published decree no. 11,310, which regulates dispositions of the National Dam Safety Policy, regulates dam supervision activities, establishes the competence to regulate the extension of the self-rescue zone for authorities acting in dam emergency situations, and presents guidelines on technical reports regarding the causes of a breach and other aspects of management of geotechnical structures. This decree also determined that companies must present guarantees for dams in an alert situation, however, the measures for measuring and executing these guarantees are still being discussed by the responsible public agencies and may result in a material impact on the value of the provision in future periods. a) De-characterization of upstream and centerline geotechnical structures As a result of the Brumadinho dam failure (note 24) and, in compliance with Law 14.066, the Company has decided to speed up the plan to “de-characterize” of all its tailings dams built under the upstream method, certain “centerline structures” and dikes, located in Brazil. The Company also operates tailings dams in Canada, including upstream compacted dams. However, the Company decided that these dams will be decommissioned using other methods, thus, the provision to carry out the decommissioning of dams in Canada is recognized as “Obligations for decommissioning assets and environmental obligations”, as presented in item (b) below. These structures are in different stages of maturity, some of them still in the conceptual engineering phase, for which the estimate of expenditures includes in its methodology a high degree of uncertainty in the definition of the total cost of the project in accordance with best market practices. The cash flow for de-characterization projects are estimated for a period up to 13 years and were discounted at present value at a rate, which increased from 5.48% to 6.14%. Changes in the provisions are as follows: Schedule of changes in the provisions, de-characterization of dam structures located in Brazil 2022 2021 Balance at January 1, 3,523 2,289 Additional provision 72 1,725 Disbursements (349) (338) Present value valuation (121) (36) Translation adjustment 253 (117) Balance at December 31, 3,378 3,523 Current liabilities 357 451 Non-current liabilities 3,021 3,072 Liabilities 3,378 3,523 Evacuation of communities In December 2022, Vale entered into an agreement to extinguish the Public Civil Action of the Nova Lima dam (B3/B4) in the amount of US$96 (R$500 million), part of which had already been registered by the Company in previous periods. Thus, the Company recorded an additional provision in the amount of US$57 (R$292 million) for the year ended December 31, 2022. Additionally, the Company is defending itself in two public civil actions filed by the Public Prosecutor's Office of the State of Minas Gerais claiming injunctions and socio-economic damages arising from the evacuations of communities located within the self-rescue zones of the dams located in Ouro Preto (Doutor) and Barão de Cocais (Sul Superior). The Company assessed that the risk of loss is possible and, at this moment, it is not possible to reliably estimate the amount of a possible loss for the Company.

Decommissioning plan and future use The Company is subject to regulations, which provide for the obligation to decommission the assets that Vale operates at the end of their useful life. These obligations are regulated by the ANM at the federal level and by environmental agencies at the state level. Among the requirements, the decommissioning plans must consider the physical, chemical and biological stability of the areas and post-closure actions for the period necessary to verify the effectiveness of the decommissioning. These obligations are accrued and are subject to critical estimates and assumptions applied to the measurement of costs by the Company. In addition, the implementation and execution of future use projects, after the decommissioning, is not required by law. However, the Company has been studying a governance to assess the future use, considering its aptitudes, post-operational usage intention, socio-economic development of the community and the characteristics of the physical and biotic environments in which Vale operates. Any future commitments, if assumed by Vale, may result in material impact on the amount of the provision. Critical accounting estimates and judgments De-characterization of dam structures Therefore, future expenditures may differ from the amounts currently provided because the realized assumptions and various other factors are not always under the Company’s control. These changes to key assumptions could result in a material impact to the amount of the provision in future reporting periods. At each reporting period, the Company will reassess the key assumptions used in the preparation of the projected cash flows and will adjust the provision, if required. Asset retirement obligations - The long-term liability is discounted at presented value using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability and the unwinds are recorded in the income statement and is reduced by payments for mine closure and decommissioning of mining assets. The accrued amounts of these obligations are not deducted from the potential costs covered by insurance or indemnities. Judgment is required to determine key assumptions used on the asset retirement obligation measurement such as, interest rate, cost of closure, useful life of the mining asset considering the current conditions of closure and the projected date of depletion of each mine. Any changes in these assumptions may significantly impact the recorded provision. Therefore, the estimated costs for closure of the mining assets are deemed to be a critical accounting estimate and annually reviewed.

The associations are requesting the cancellation of Vale's mining and environmental licenses to operate those mines, mainly claiming that the mining activities are contaminating the water springs in the region. Those mining operations are currently suspended, and the Company is defending itself against the lawsuit, which it believes that the likelihood of loss is possible, however, it is not yet possible to estimate the amount of a potential loss due to the interruption of these operations or any potential agreement to mitigate and compensate. In addition, the Company is also a party to public civil actions filed by the Public Ministry of the State of Minas Gerais and by the municipality of Juceaba requesting the Company to stop disposing tailings at Maravilhas II and III dams (Vargem Grande complex), Forquilhas V (Fábrica complex) and Dam 7 (Viga mine).

The liability is accounted against an expense in the income statement. This obligation is updated based on the developments of the judicial process or interest accretion and can be reversed if the expectation of loss is not considered probable due to changes in circumstances or when the obligation is settled. Litigation Contingent assets are disclosed when the related economic benefits are probable and are only recognized in the financial statements in the period in which their realization is virtually certain. Critical accounting estimates and judgments Litigations are contingent by nature, that is, it will be resolved when one or more future event occurs or fails to occur. Typically, the occurrence or not of such events is outside of the Company’s control. Legal uncertainties involve the application of significant estimates and judgments by management regarding the potential outcomes of future events.

The fair value of the programs is recognized on a straight-line basis over the three-year required service period, net of estimated losses. Matching Program For the Matching program, the participants can acquire Vale’s common shares in the market without any benefits being provided by Vale. If the shares acquired are held for a period of three years and the participants keep an employment relationship with Vale, the participant is entitled to receive from Vale an award in shares, equivalent to the number of shares originally acquired by the executive. It should be noted that, although a specific custodian of the shares is defined by Vale, the share initially purchased by the executives have no restriction and can be sold at any time. However, if it’s done before the end of the three-year-vesting period, they would lose its right of receiving the related award to be paid by Vale. Performance Shares Units (“PSU”) Under the PSU, eligible executives can earn, during a three-year vesting cycle, an award equivalent to the market value of a certain number of common shares and conditioned to Vale's performance factor measured based on Total Shareholder Return ("TSR") and Environmental, Social and Governance ("ESG") metrics. It is comprised of 75 25 d) New accounting policy adopted in 2021 IFRS 2 defines that the accounting for share-based payments depends on the form of settlement of the plans, which can be “cash-settled” or “equity-settled”. When a plan is settled in cash, the payment obligation to the employee is recognized as a liability, which is updated to fair value recognized in the income statement at each reporting date and on the settlement date of the obligation. When the plan is settled with equity instruments, the fair value of the plan is calculated only on the grant date of the benefit and the fair value of the plan is recognized in the income statement for the year on a straight-line basis to equity over the period of service required. New accounting policy adopted in 2021 Until December 2020, the long-term incentive programs for the Company's executives, were recorded as liabilities based on the practice adopted by the Company to settle its obligation related to these programs with cash payment instead of Vale’s shares for its executives. On April 30, 2021, the modification of the Regulation of the Performance Share Unit program(“PSU”) was approved at the Ordinary and Extraordinary Annual General Meeting (“date of modification”), enabling the use of treasury shares of the Company to settle the obligation. Thus, the plans started to be treated as “equity-settled” and their fair value was remeasured on the modification date. Remeasurement of the fair value of plans The fair value of the Matching program was estimated using the Company's share price and ADR on the modification date, in the amount of R$ 109.02 20.12 1,222,721 2,154,534 1,046,255 For the PSU, the program was remeasured by estimating the performance factor using Monte Carlo simulations for the Return to Shareholders Indicator and health and safety and sustainability indicators. The assumptions used for the Monte Carlo simulations are shown in the table below, as well as the result used to calculate the expected value of the total performance factor. Summary of assumptions used for the Monte Carlo simulation 2021 Granted shares 1,474,723 Date shares were granted 01/03/2021 VALE (BRL) 109.02 VALE ON (USD) 20.12 Expected volatility 39.00 Expected term (in years) 3 Expected shareholder return indicator 51.20 Expected performance factor 60.96 e) Measurement of the fair value of the 2022 plans On March 30, 2022, a new cycle of the Matching program started and the Company estimates a fair value based on the prices of Company’s shares and ADRs on the share grant date of US$ 20.03 95.87 1,437,588 1,046,255 During 2022, a new cycle of the PSU program has started as well and the Company will grant 1,709,955 1,474,723 Summary of assumptions used for the Monte Carlo simulation 2022 Granted shares 1,709,955 Date shares were granted 01/03/2022 VALE (BRL) 78.00 VALE ON (USD) 13.81 Expected volatility 39.00 Expected term (in years) 3 Expected shareholder return indicator 51.20 Expected performance factor 53.08 Accounting policy Employee benefits i. Current benefits – wages, vacations and related taxes Employee benefits Payments of benefits such as wages or accrued vacation, as well the related social security taxes over those benefits are recognized monthly in income, on an accrual basis. ii. Current benefits – profit sharing program The Company has the Annual Incentive Program (AIP) based on Team and business unit’s contribution and Company-wide performance through operational cash generation. The Company makes an accrual based on evaluation periodic of goals achieved and Company result, using the accrual basis and recognition of present obligation arising from past events in the estimated outflow of resources in the future. The accrual is recorded as cost of goods sold and services rendered or operating expenses in accordance with the activity of each employee. iii. Non-current benefits – long-term incentive programs The Company has established a procedure for awarding certain eligible executives (Matching and Performance Share unit (“PSU”) Programs) with the goal of encouraging employee retention and optimum performance. Share-based long-term compensation programs are equity-settled, under which the Company receives employee services as consideration for equity instruments. The fair value of employee services received in exchange for the grant of options is recognized as an expense. The total amount of expenses is recognized during the period in which the right is acquired; period during which the specific vesting conditions are met. iv. Non-current benefits – pension costs and other post retirement benefits The Company has several retirement plans for its employees. For defined contribution plans, the Company's obligations are limited to a monthly contribution linked to a pre-defined percentage of the remuneration of employees enrolled into these plans. For defined benefit plans, actuarial calculations are periodically obtained for liabilities determined in accordance with the Projected Unit Credit Method in order to estimate the Company’s obligation. The liability recognized in the statement of financial position represents the present value of the defined benefit obligation as at that date, less the fair value of plan assets. The Company recognized in the income statement the costs of services, the interest expense of the obligations and the interest income of the plan assets. The remeasurement of gains and losses, return on plan assets (excluding the amount of interest on return of assets, which is recognized in income for the year) and changes in the effect of the ceiling of the active and onerous liabilities are recognized in comprehensive income for the year. For overfunded plans, the Company recognizes the net defined benefit assets limited to the present value of the economic benefits available as refunds or reductions in future contributions, considering minimum funding requirements applicable. For underfunded plans, the Company recognizes net defined benefit liabilities. The gain or loss on recognition/remeasurement of these net assets/liabilities are recognized in income statement or in comprehensive income, when arising from the actuarial valuation. Critical accounting estimates and judgments Post retirement benefits for employees - At the end of each year the Company and external actuaries review the assumptions that will be used for the following year. These assumptions are used in determining the fair values of assets and liabilities, costs and expenses and the future values of estimated cash outflows, which are recorded in the plan obligations.

These shares are recognized in a specific account as a reduction of equity to the acquisition value and maintained at the cost of the transaction. Incremental costs directly attributable to the issue of new shares or options are recognized in equity as a deduction from the amount raised, net of taxes. Stockholders' equity Shareholder’s remuneration - The shareholder’s remuneration is paid on dividends and interest on capital. This remuneration is recognized as a liability in the financial statements of the Company based on bylaws. Any amount above the minimum mandatory remuneration approved by the by-laws shall only be recognized in current liabilities on the date that is approved by shareholders. The Company is permitted to distribute interest attributable to equity. The calculation is based on the equity amounts as stated in the statutory accounting records and the interest rate applied may not exceed the Brazilian Government Long-term Interest Rate (“TJLP”) determined by the Central Bank of Brazil. Also, such interest may not exceed 50% of the net income for the year or 50% of retained earnings plus profit reserves as determined by Brazilian corporate law. The benefit to the Company, as opposed to making a dividend payment, is a reduction in the income tax burden because this interest charge is tax deductible in Brazil. Income tax of 15% is withheld on behalf of the shareholders relative to the interest distribution. Under Brazilian law, interest attributed to equity is considered as part of the annual minimum mandatory dividend. This notional interest distribution is treated for accounting purposes as a deduction from equity in a manner similar to a dividend and the tax deductibility recorded in the income statement.

Basis Of Preparation Of Financial Statements
Principles for consolidation	a) Principles for consolidation The Company's financial statements reflect the assets, liabilities and transactions of the Parent Company and its direct and indirect subsidiaries (“subsidiaries”). Intercompany balances and transactions, which include unrealized profits, are eliminated. A list of the most relevant companies, including subsidiaries, associates and joint ventures, and the accounting policies applied in the preparation of the consolidated financial statements are described in note 15. b) Functional currency and presentation currency The financial statements of the Company and its associates and joint ventures are measured using the currency of the primary economic environment in which the entity operates (“functional currency”), in the case of the Parent Company is the Brazilian real (“R$”). For presentation purposes, these financial statements are presented in United States dollar (“US$”) as the Company believes that this is how international investors analyze the financial statements. The income statement and cash flows statements of the investees, with a different functional currency from the Parent Company, are translated into Brazilian real at the average monthly exchange rate, the assets and liabilities are translated at the final rate and the other equity items are translated at the historical rate. All monetary exchange differences are recognized in comprehensive income as “Translation adjustments”. When a foreign operation is totally or partially disposed, the monetary exchange differences that were recorded in the equity are recognized in the income statement for the year, see accounting policy in note 15 of these financial statements. The main exchange rates used by the Company to translate its foreign operations are as follows: Schedule of exchange rates used to translate its foreign operations Closing rate Average rate 2022 2021 2020 2022 2021 2020 US Dollar ("US$") 5.2177 5.5805 5.1967 5.1655 5.3956 5.1578 Canadian dollar ("CAD") 3.8550 4.3882 4.0771 3.9705 4.3042 3.8480 Euro ("EUR") 5.5694 6.3210 6.3779 5.4420 6.3784 5.8989 c) Critical accounting estimates and judgments The preparation of financial statements requires the use of critical accounting estimates and Management also needs to exercise judgement in applying the Company’s accounting policies. The Company makes estimates about the future based on assumptions. Accounting estimates and judgments are continually evaluated and are based on management's experience and knowledge, information available at the date of the financial statements and other factors, including expectations of future events that are considered reasonable under the circumstances. Accounting estimates, by definition, will seldom equal the actual results. The areas involving significant estimates or judgements or complexity, and of items which are more likely to be materially adjusted due to estimates and assumptions are presented in the following notes: Note Significant estimates and judgments 7 Streaming transactions 8 Deferred income taxes and uncertain tax positions 15 Consolidation 18 Mineral reserves and mines useful life 19 Impairment of non-current assets 20 Fair values estimate 24 Liabilities related to Brumadinho 25 Liabilities related to associates and joint ventures 26 Provision for de-characterization of dam structures and asset retirement obligations 28 Litigation 29 Employee post retirement obligation d) A ccounting impacts related to environmental, social and governance initiatives (“ESG”) The Company has assumed commitments to integrate sustainability into its business through a comprehensive approach, based on systematic planning and execution. Prioritizing risk and impact management and establishing a social, economic and environmental legacy in the locations where Vale operates. Investments announced by the Company's and its strategy for ESG initiatives were assessed in the context of the Company's critical accounting judgments and key estimates. Future changes in this strategy or in the global scenario may affect the Company's main estimates and may result in material impacts on the income statement and on assets and liabilities accounting balances of the Company in successive fiscal years. The main actions taken or announced to date, which have already resulted or will result in a direct impact on the Company's financial statements are described below. Other initiatives are detailed in the Integrated Report, made available on the Company's website, which were not incorporated by reference. Environmental pillar Climate changes · The Company is committed to reduce carbon emissions from its mining activities, in line with the Paris Agreement objective of limiting global warming to well below 2°C (3.6 °F). The Company's strategy considers as main objectives: (i) 33% reduction by 2030 of the emissions released into the atmosphere as a direct result of its operations ("scope 1") and of indirect emissions, from the electric energy acquired by the Company (“scope 2”), already considering the increase in production levels projected for the upcoming years; (ii) 100% of electricity consumption from renewable sources by 2030; (iii) 15% reduction by 2035 of indirect emissions not included in scope 2 (“scope 3”); and (iv) neutrality of scope 1 and 2 emissions by 2050. · To achieve the scope 1 and 2 commitments, the Company announced investments between US$4 billion and US$6 billion up to 2030 to develop low carbon solutions, such as electrification, use of biofuels and generation and use of renewable energy. The effective disbursements with these investments will be capitalized or expensed, depending on its nature and function, in the period in which they are incurred. Low carbon products and renewable energy · In April 2022, Vale completed the sale of its coal operations located in Mozambique and Malawi, in line with its commitment of decarbonization and sustainable mining. As a result, the Company has no longer coal operations (note 16a). · In June 2022, the Company announced the creation of an operation of Corporate Venture Capital (“Vale Ventures”), the objective is to invest approximately US$100 in sustainable mining initiatives.

In addition, Vale also signed a memorandum of understanding with the steelmaker Stahl-Holding-Saar GmbH (“SHS”), to seek solutions focused on the carbon-neutral steel production process, including the use of Vales green iron ore briquette. Investments made will be accounted for when they are incurred. · In November 2022, the Company started the Sol do Cerrado project, for construction of a solar energy plant located in Minas Gerais, the capacity will represent approximately 16% of the energy consumed by Vale in Brazil. The start of operation is expected for July 2023, it will contribute to Vale's renewable energy commitments and reduction of carbon emissions. As at December 31, 2022, the Company invested US$197 (R$1,030 million) as property, plant and equipment (note 18). · In February 2021, the Company concluded an investment of US$6 in Boston Electrometallurgical Company (note 14) to acquire a minority interest and promote the development of a technology focused on reducing carbon dioxide emissions in the steel production. Forest conservation · In November 2022, Vale announced the creation of the company Biomas, in which it will hold a 14.28% stake, together with Itaú Unibanco, Marfrig, Rabobank, Santander and Suzano. The Company will invest US$4 (R$20 million) to set up this company, which will carry out restoration, conservation and preservation activities for 4 million hectares of forests in Brazil, in line with the forest protection strategy. Completion of the transaction is subject to customary regulatory approvals. · In 2021, Vale signed partnerships with three Conservation Units managed by the Chico Mendes Institute for Biodiversity Conservation. Together, these Biological Reserves help to protect more than 62 thousand hectares of Atlantic Forest, in three Brazilian states. Additionally, Vale supported the development of five agroforestry businesses that implemented productive recovery models in 5,125 hectares in a pilot phase, totaling, between 2020 and 2021, an area of more than 6 thousand hectares. Investments made will be accounted for when they are incurred. Social pillar Sustainable mining · In 2019, the Company invested US$ 496 1,884 · The implementation and execution of future use projects, after the decommissioning, is not required by law. However, the Company has been studying a governance to assess the future use, considering its aptitudes, post-operational usage intention, socio-economic development of the community and the characteristics of the physical and biotic environments in which Vale operates. Any future commitments, if assumed by Vale, may result in material impact on the amount of the provision (note 26). · Within the scope for community safety, as a preventive step, Vale considers social data on all people inserted in the self-rescue zones of its flood spots and carries out preventive relocation or emergency evacuation of communities located in these zones when the dam emergency level rises. In 2022, the Company recorded a provision in the amount of US$ 57 292 Communities · In 2022, the Company recorded a provision in the amount of US$ 7 39 · In 2022, the Company also entered into an indemnity agreement with the indigenous communities Xikrin do Cateté and Kayapó (note 28b).

Revenue	Revenue A relevant proportion of Vale’s sales are under Cost and Freight (“CFR”) and Cost, Insurance and Freight (“CIF”) Incoterms, in which the Company is responsible for providing shipping services after the date that Vale transfers control of the goods to the customers. Shipping services for CFR and CIF contracts are considered as a separate performance obligation in which a proportion of the transaction price is allocated and recognized over time as the shipping services are provided. In general, the contract payment terms consider the upfront payments or the use of letters of credit. The payment terms do not have a significant financing component. In some cases, the sale price is determined on a provisional basis at the date of sale and adjustments to the sale price subsequently occur based on movements in the quoted market or contractual prices up to the date of final pricing. Revenue is recognized based on the estimated fair value of the total consideration receivable, and the provisionally priced sale mechanism embedded within these sale arrangements has the character of a derivative. Accordingly, the fair value of the final sale price adjustment is re-estimated continuously and changes in fair value are recognized as operational revenue in the income statement.

Critical accounting estimates and judgments Defining the result on sale of mineral interest and the contractual liabilities portion of the streaming transaction it is required the use of critical accounting estimates including, but not limited to: (i) allocation of costs between the product and the by-product based on relative prices; (ii) expected margin for the independent components (sale of mineral rights and service for gold and cobalt extraction); and (iii) discount rates used to measure the present value of future inflows and outflows.

Income taxes (Policies)

Income Taxes
Income taxes	The Brazilian corporate tax law requires the taxation on the income generated from foreign subsidiaries and, therefore, income tax charge is calculated using the tax rate enacted at the end of the reporting period in Brazil. The effects of the income tax calculation in the consolidated financial statements are calculated by applying the differential between the Brazilian income tax rate and the local income tax rate of each jurisdiction where the Company’s subsidiaries operate and generate taxable income. Income taxes Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation and it establishes provisions, where appropriate, on the basis of amounts expected to be paid to the tax authorities. The liabilities related to uncertain tax positions are recorded only after determining, based on the position of its internal and external legal advisors, a more-likely-than-not probability that the uncertain tax positions will withstand challenge, if any, from taxing authorities. Deferred income taxes are recognized based on temporary differences between carrying amount and the tax basis of assets and liabilities as well as tax losses carryforward. However, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill. Deferred income tax is also not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that, at the time of the transaction, affects neither accounting nor taxable profit or loss. Deferred tax assets and liabilities are offset where there is a legally enforceable right to offset current tax assets and liabilities and where the deferred tax balances relate to the same taxation authority. The deferred tax assets arising from tax losses and temporary differences are not recognized when it is not probable that future taxable profit will be available against which temporary differences and/or tax losses can be utilized. Current and deferred tax is recognized in profit or loss, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this case, the tax is also recognized in other comprehensive income or directly in equity, respectively.

Investments in associates and joint arrangements	Investments in associates and joint arrangements 20 50 Joint arrangements are all entities over which the Company has shared control with one or more parties. Joint arrangement investments are classified as either joint operations or joint ventures depending on the contractual rights and obligations of each investor. The joint operations are recorded in the financial statements to represent the Company’s contractual rights and obligations. Accordingly, the assets, liabilities, income and expenses related to the joint operation are recorded individually in the financial statements. Interests in joint ventures are accounted for using the equity method, after initially being recognized at cost. The Company investment in joint ventures includes the goodwill identified in the acquisition, net of any impairment loss. The Company interest in the profits or losses of its joint ventures is recognized in the income statement and participation in the changes in reserves is recognized in the Company's reserves. When the Company’s interest in the losses of an associate or joint venture is equal to or greater than the carrying amount of the investment, including any other receivables, the Company does not recognize additional losses, unless it has incurred obligations or made payments on behalf of the joint venture.
Cumulative translation adjustments	Cumulative translation adjustments Thus, the Company has determined as its accounting policy that a capital reduction in an investment in a foreign operation should be treated under the absolute value approach as described in ii) above. Therefore, the exchange differences recorded in equity are reclassified to the income statement in the same proportion as the reduction in the net investment held in the foreign operation.
Critical accounting estimates and judgments	Critical accounting estimates and judgments Judgment is required in some circumstances to determine whether after considering all relevant factors, the Company has either control, joint control or significant influence over an entity. Significant influence includes situations of collective control. The Company holds the majority of the voting capital in five joint arrangements (Aliança Geração de Energia S.A., Aliança Norte Energia Participações S.A., Companhia Hispano-Brasileira de Pelotização, Companhia Ítalo-Brasileira de Pelotização and Companhia Nipo-Brasileira de Pelotização), but management has concluded that the Company does not have a sufficiently dominant voting interest to have the power to direct the activities of these entities. As a result, these entities are accounted under equity method due to shareholder’s agreements where relevant decisions are shared with other parties. Vale and Sumitomo Metal Mining Co. Ltd. (“SMM”) own a 44.3% and 15% equity interest in PT Vale Indonesia Tbk (“PTVI”), respectively, for a total of 59.3% interest in PTVI. Vale and SMM have a Shareholders' Agreement ("Block voting agreement"), establishing that SMM will follow Vale's guidelines in decision-making on financial and operational matters relevant to the management of PTVI and, therefore, the Company consolidates PTVI in its financial statements.

Property, plant, and equipment	Property, plant, and equipment Mineral properties developed internally are determined by (i) direct and indirect costs attributed to build the mining facilities, (ii) financial charges incurred during the construction period, (iii) depreciation of other fixed assets used during construction, (iv) estimated decommissioning and site restoration expenses, and (v) other capitalized expenditures during the development phase (phase when the project demonstrates its economic benefit to the Company, and the Company has ability and intention to complete the project). The depletion of mineral properties is determined based on the ratio between production and total proven and probable mineral reserves. Property, plant and equipment, other than mineral properties are depreciated using the straight-line method based on the estimated useful lives, from the date on which the assets become available for their intended use and are capitalized, except for land which is not depreciated. The estimated useful lives are as follows: Schedule of estimated useful lives of property, plant and equipment Useful life Buildings 3 50 Facilities 3 50 Equipment 3 40 Locomotives 12 25 Wagons 30 45 Railway equipment 5 37 Vessels 20 25 Other 2 50 The residual values and useful lives of assets are reviewed at the end of each reporting period and adjusted if necessary.

Stripping Costs	(iv) Stripping Costs Post-production stripping costs are included in the cost of inventory, except when a new project is developed to permit access to a significant ore deposit. In such cases, the cost is capitalized as a non-current asset and is amortized during the extraction of the ore deposits, over the useful life of the ore deposits.
Leases	Leases The Company does not recognize right-of-use assets and liabilities for leases with less than 12 months of lease term and/or leases of low-value assets. The payments associated to these leases are recognized as an expense on a straight-line basis over the lease term. The lease liability is initially measured at the present value of the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company’s incremental borrowing rate. Lease payments included in the measurement of the lease liability comprise: (i) fixed payments, including in-substance fixed payments; (ii) variable lease payments that depend on an index or a rate; and (iii) the exercise price under a purchase option or renewal option that are under the Company’s control and is reasonably certain to be exercised. The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in an index or rate. When the lease liability is remeasured, a corresponding adjustment is made to the carrying amount of the right-of-use asset or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero.
Mineral reserves	Mineral reserves The estimated volume of mineral reserves is used as basis for the calculation of depletion of the mineral properties, and also for the estimated useful life which is a major factor to quantify the provision for asset retirement obligation, environmental recovery of mines and impairment of long lived asset. Any changes to the estimates of the volume of mine reserves and the useful lives of assets may have a significant impact on the depreciation, depletion and amortization charges and assessments of impairment.

Impairment Reversal Impairment And Disposals Of Non-current Assets
Impairment of non-financial assets	Impairment of non-financial assets FVLCD is generally determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset from a market participant’s perspective, including any expansion prospects. VIU model is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form. Value in use is determined by applying assumptions specific to the Company’s continued use and cannot take into account future development. These assumptions are different to those used in calculating fair value and consequently the VIU calculation is likely to give a different result to a FVLCD calculation. Assets that have an indefinite useful life and are not subject to amortization, such as goodwill, are tested annually for impairment. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (CGU). Goodwill is allocated to Cash Generating Units or Cash Generating Units groups that are expected to benefit from the business combinations in which the goodwill arose and are identified in accordance with the operating segment. Non-current assets (excluding goodwill) in which the Company recognized impairment in the past are reviewed whenever events or changes in circumstances indicate that the impairment may no longer be applicable. In such cases, an impairment reversal will be recognized. Onerous Contracts - Critical accounting estimates and judgments Significant judgements, estimates and assumptions are required to determine whether an impairment trigger has occurred and to prepare the Company’s cash flows. Management uses the budgets approved as a starting point and key assumptions are, but not limited to: (i) mineral reserves and mineral resources measured by internal experts; (ii) costs and investments based on the best estimate of projects as supported by past performance; (iii) sale prices consistent with projections available in reports published by industry considering the market price when appropriate; (iv) the useful life of each cash-generating unit (ratio between production and mineral reserves); and (v) discount rates that reflect specific risks relating to the relevant assets in each cash-generating unit. These assumptions are susceptible to risks and uncertainties and may change the Company’s projection and, therefore, may affect the recoverable value of assets.

Financial And Capital Risk Management
Derivative financial instruments	The Company uses financial instruments to hedge its exposure to certain market risks arising from operational, financing and investing activities. Derivatives are included within financial assets or liabilities at fair value through profit or loss unless they are designated as effective hedging instruments (hedge accounting). Derivative financial instruments At the beginning of the hedge operations, the Company documents the type of hedge, the relation between the hedging instrument and hedged items, its risk management objective and strategy for undertaking hedge operations. The Company also documents, both at hedge inception and on an ongoing basis that the hedge is expected to continue to be highly effective. The Company has elected to adopt the new general hedge accounting model in IFRS 9 and designates certain derivatives as either: Cash flow hedge - The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in equity within "Unrealized fair value gain (losses)". The gain or loss relating to the ineffective portion is recognized immediately in the income statement. When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognized in profit or loss when the transaction is recognized in the income statement. Net investment hedge - Hedges of net investments in foreign operations are accounted for similarly to cash flow hedges. Any gain or loss on the hedging instrument relating to the effective portion of the hedge is recognized in equity within "Cumulative translation adjustments". The gain or loss relating to the ineffective portion is recognized immediately in the income statement. Gains and losses accumulated in equity are included in the statement of income when the foreign operation is partially or fully disposed of or sold. Derivatives at fair value through profit or loss - Certain derivative instruments do not qualify for hedge accounting. Changes in the fair value of any of these derivative instruments are recognized immediately in the income statement. Critical accounting estimates and judgments The fair values of financial instruments that are not traded in active markets are determined using valuation techniques. Vale uses its own judgment to choose between the various methods. Assumptions are based on the market conditions, at the end of the year. An analysis of the impact if actual results are different from management's estimates is present under “Sensitivity analysis of derivative financial instruments”.

All financial liabilities are initially measured at fair value, net of transaction costs incurred and are subsequently carried at amortized cost and updated using the effective interest rate method. Excepts for Participative shareholders’ debentures and Derivative financial instruments that are measured at FVTPL. Fair value hierarchy - Level 1: The fair value of financial instruments traded in active markets (e.g. derivatives and publicly traded shares) is based on quoted market prices at the end of the financial statements period. Level 2: The fair value of financial instruments that are not traded in an active market (e.g. over the counter derivatives) is determined using valuation techniques that maximize the use of observable market data. If all significant data required for the fair value of an instrument are observable, the instrument is included in level 2. Level 3: If one or more of the significant data are not based on observable market data, the instrument is included in level 3. The fair value of derivatives classified as level 3 is estimated using discounted cash flows and option valuation models with unobservable inputs of discount rates, stock prices and commodity prices.

Moreover, the main critical assumptions and estimates applied in the Germano dam provision considers, among others: (i) volume of the waste to be removed based on historical data available and interpretation of the enacted laws and regulations; (ii) location availability for the tailings disposal; and (iii) acceptance by the authorities of the proposed engineering methods and solution. As a result, future expenditures may differ from the amounts currently provided and changes to key assumptions could result in a material impact to the amount of the provision in future reporting periods.

Asset retirement obligations - The long-term liability is discounted at presented value using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability and the unwinds are recorded in the income statement and is reduced by payments for mine closure and decommissioning of mining assets. The accrued amounts of these obligations are not deducted from the potential costs covered by insurance or indemnities. Judgment is required to determine key assumptions used on the asset retirement obligation measurement such as, interest rate, cost of closure, useful life of the mining asset considering the current conditions of closure and the projected date of depletion of each mine. Any changes in these assumptions may significantly impact the recorded provision. Therefore, the estimated costs for closure of the mining assets are deemed to be a critical accounting estimate and annually reviewed.

Litigations
Litigation	A provision is recognized when it is considered probable that an outflow of resources will be required to settle the obligation and can be reliably estimated. The liability is accounted against an expense in the income statement. This obligation is updated based on the developments of the judicial process or interest accretion and can be reversed if the expectation of loss is not considered probable due to changes in circumstances or when the obligation is settled. Litigation Contingent assets are disclosed when the related economic benefits are probable and are only recognized in the financial statements in the period in which their realization is virtually certain. Critical accounting estimates and judgments Litigations are contingent by nature, that is, it will be resolved when one or more future event occurs or fails to occur. Typically, the occurrence or not of such events is outside of the Company’s control. Legal uncertainties involve the application of significant estimates and judgments by management regarding the potential outcomes of future events.

Employee Benefits
New accounting policy adopted in 2021	IFRS 2 defines that the accounting for share-based payments depends on the form of settlement of the plans, which can be “cash-settled” or “equity-settled”. When a plan is settled in cash, the payment obligation to the employee is recognized as a liability, which is updated to fair value recognized in the income statement at each reporting date and on the settlement date of the obligation. When the plan is settled with equity instruments, the fair value of the plan is calculated only on the grant date of the benefit and the fair value of the plan is recognized in the income statement for the year on a straight-line basis to equity over the period of service required. New accounting policy adopted in 2021 Until December 2020, the long-term incentive programs for the Company's executives, were recorded as liabilities based on the practice adopted by the Company to settle its obligation related to these programs with cash payment instead of Vale’s shares for its executives. On April 30, 2021, the modification of the Regulation of the Performance Share Unit program(“PSU”) was approved at the Ordinary and Extraordinary Annual General Meeting (“date of modification”), enabling the use of treasury shares of the Company to settle the obligation. Thus, the plans started to be treated as “equity-settled” and their fair value was remeasured on the modification date.
Employee benefits	i. Current benefits – wages, vacations and related taxes Employee benefits Payments of benefits such as wages or accrued vacation, as well the related social security taxes over those benefits are recognized monthly in income, on an accrual basis. ii. Current benefits – profit sharing program The Company has the Annual Incentive Program (AIP) based on Team and business unit’s contribution and Company-wide performance through operational cash generation. The Company makes an accrual based on evaluation periodic of goals achieved and Company result, using the accrual basis and recognition of present obligation arising from past events in the estimated outflow of resources in the future. The accrual is recorded as cost of goods sold and services rendered or operating expenses in accordance with the activity of each employee. iii. Non-current benefits – long-term incentive programs The Company has established a procedure for awarding certain eligible executives (Matching and Performance Share unit (“PSU”) Programs) with the goal of encouraging employee retention and optimum performance. Share-based long-term compensation programs are equity-settled, under which the Company receives employee services as consideration for equity instruments. The fair value of employee services received in exchange for the grant of options is recognized as an expense. The total amount of expenses is recognized during the period in which the right is acquired; period during which the specific vesting conditions are met. iv. Non-current benefits – pension costs and other post retirement benefits The Company has several retirement plans for its employees. For defined contribution plans, the Company's obligations are limited to a monthly contribution linked to a pre-defined percentage of the remuneration of employees enrolled into these plans. For defined benefit plans, actuarial calculations are periodically obtained for liabilities determined in accordance with the Projected Unit Credit Method in order to estimate the Company’s obligation. The liability recognized in the statement of financial position represents the present value of the defined benefit obligation as at that date, less the fair value of plan assets. The Company recognized in the income statement the costs of services, the interest expense of the obligations and the interest income of the plan assets. The remeasurement of gains and losses, return on plan assets (excluding the amount of interest on return of assets, which is recognized in income for the year) and changes in the effect of the ceiling of the active and onerous liabilities are recognized in comprehensive income for the year. For overfunded plans, the Company recognizes the net defined benefit assets limited to the present value of the economic benefits available as refunds or reductions in future contributions, considering minimum funding requirements applicable. For underfunded plans, the Company recognizes net defined benefit liabilities. The gain or loss on recognition/remeasurement of these net assets/liabilities are recognized in income statement or in comprehensive income, when arising from the actuarial valuation. Critical accounting estimates and judgments Post retirement benefits for employees - At the end of each year the Company and external actuaries review the assumptions that will be used for the following year. These assumptions are used in determining the fair values of assets and liabilities, costs and expenses and the future values of estimated cash outflows, which are recorded in the plan obligations.

Equity (Policies)

Equity (Policies)	12 Months Ended

Equity
Stockholders' equity	Share capital and treasury shares - The Company holds shares in treasury for a future sale, cancellation or for the payment of the executives' long-term compensation programs. These shares are recognized in a specific account as a reduction of equity to the acquisition value and maintained at the cost of the transaction. Incremental costs directly attributable to the issue of new shares or options are recognized in equity as a deduction from the amount raised, net of taxes. Stockholders' equity Shareholder’s remuneration - The shareholder’s remuneration is paid on dividends and interest on capital. This remuneration is recognized as a liability in the financial statements of the Company based on bylaws. Any amount above the minimum mandatory remuneration approved by the by-laws shall only be recognized in current liabilities on the date that is approved by shareholders. The Company is permitted to distribute interest attributable to equity. The calculation is based on the equity amounts as stated in the statutory accounting records and the interest rate applied may not exceed the Brazilian Government Long-term Interest Rate (“TJLP”) determined by the Central Bank of Brazil. Also, such interest may not exceed 50% of the net income for the year or 50% of retained earnings plus profit reserves as determined by Brazilian corporate law. The benefit to the Company, as opposed to making a dividend payment, is a reduction in the income tax burden because this interest charge is tax deductible in Brazil. Income tax of 15% is withheld on behalf of the shareholders relative to the interest distribution. Under Brazilian law, interest attributed to equity is considered as part of the annual minimum mandatory dividend. This notional interest distribution is treated for accounting purposes as a deduction from equity in a manner similar to a dividend and the tax deductibility recorded in the income statement.

[1]In March 2021, the UK Financial Conduct Authority (“FCA”), the financial regulator in the United Kingdom, announced the discontinuation of the LIBOR rate for all terms in pounds, euros, Swiss francs, yen and for terms of one week and two months in dollars at the end of December 2021 and the other terms at the end of June 2023. Vale is in negotiations with some financial institutions to replace the reference interest rate of its financial contracts from LIBOR to Secured Overnight Financing Rate ("SOFR"), with spread adjustments to match the transaction costs. The Company does not expect material impacts on the cash flows of these operations.
