Item 2.  Identity and Background.

The response set forth in Item 2 of the Schedule 13D is hereby amended by deleting the previous response in its entirety and replacing with the following:

This statement is filed by Valepar S.A. (“Valepar”), a company duly organized and existing in the Federative Republic of Brazil.  Valepar was formed for the purpose of holding a voting interest in Vale.  The address of Valepar’s principal executive office is Avenida das Américas, 700 — Bloco 8 — Loja 318 22640-100 Rio de Janeiro, RJ, Brazil.

Certain information required by this Item 2 is provided on Exhibit 1, which is incorporated by reference herein for each executive officer and director of Valepar as of the date of the event which requires the filing of this statement, May 10, 2017.

Neither Valepar nor any of its directors or executive officers as of the date of the event which requires the filing of this statement, May 10, 2017, has, during the five years since such date, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

Neither Valepar nor any of its directors or executive officers as of the date of the event which requires the filing of this statement, May 10, 2017 has, during the five years since such date, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding been subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 4.  Purpose of Transaction.

The response set forth in Item 4 of the Schedule 13D is hereby amended to add the following paragraphs:

Litel Participações S.A., Litela Participações S.A., Bradespar S.A., Mitsui & Co., Ltd. and BNDES Participações S.A. – BNDESPAR (together, the “Shareholders”) are party to a new Valepar shareholders agreement, executed on February 19, 2017, (the “Shareholders Agreement”) that entered into effect on May 10, 2017.  The Shareholders Agreement, along with the standard provisions in connection with voting rights and right of first refusal for the acquisition of the Shareholders’ shares, provides for the submission to Vale of a proposal for the purpose of enabling the listing of Vale on BM&FBOVESPA’s Novo Mercado special segment and making Vale a company without defined control (the “Proposal”).  On May 11, 2017, Valepar, as instructed by the Shareholders, submitted the Proposal (attached hereto as Exhibit 3) to Vale.  The Proposal is binding on the Shareholders and is subject to approval by Vale’s corporate bodies. The Shareholders Agreement will be in force for a term of 6 months from the date it takes effect or until the merger of Valepar into Vale, whichever occurs earlier.

3

The transaction envisaged by the Proposal is composed of a series of indivisible and interdependent steps, whose effectiveness is subject to the successful performance of the other steps. The Proposal comprises, beyond the performance of all acts and procedures imposed by the applicable legal provisions and rules:

i.                  Voluntary conversion of Vale class A preferred shares into common shares, based on the conversion rate of 0.9342 common shares for each Vale class A preferred share, based on the average closing price of the common shares and preferred shares over the 30 trading sessions on the BM&FBOVESPA prior to February 17, 2017 (inclusive), weighted by the volume of shares traded in such trading sessions (the “Voluntary Conversion”);

ii.               Amendment of Vale’s bylaws so as to adjust them, as much as possible, to Novo Mercado rules so Vale may be effectively listed on such special segment (the “Bylaws Amendment”); and

iii.            The merger of Valepar into Vale at an exchange ratio that contemplates a 10% increase in the number of shares held by the shareholders of Valepar compared to Valepar’s current shareholding interest, and represents a dilution of approximately 3% of the shareholding interest held by the other shareholders in Vale the (“Merger” and, together with the Voluntary Conversion and the Bylaws Amendment, the “Transaction”).

Pursuant to item “iii” above, Valepar’s Shareholders will receive 1.2065 Common Shares for each Valepar share held by them. As a result, Vale will issue 173,543,667 new Common Shares, all registered and without par value, in favor of Valepar’s shareholders. Consequently, Valepar’s shareholders will own a total of 1,908,980,340 Vale Common Shares after the merger of Valepar.

The implementation of the Proposal is subject to (i) the approval of the Proposal, including the merger of Valepar into Vale, by Valepar’s and Vale’s corporate bodies; and (ii) the acceptance by at least 54.09% of class A preferred shares of the voluntary conversion, as mentioned in item “i” above, within the maximum term of 45 days from the shareholders’ meeting decision on the matter, resulting in a combined shareholding interest held by the Shareholders of less than 50% of Vale’s total common shares. Valepar and the Shareholders will not exercise their voting right at Vale’s shareholders’ meetings in connection with the approval of the voluntary conversion of the Vale class A preferred shares into common shares and the merger of Valepar.

On the date of effectiveness of the Transaction, if it is approved, the Shareholders will execute a new shareholders’ agreement (the “Vale Agreement”), in order to give Vale stability and to adapt its corporate governance structure during the period of transition to its new corporate structure without defined control. The Vale Agreement, a form of which is attached to Shareholders Agreement, will bind only 20% of the totality of Vale’s Common Shares, and will be in force until November 9, 2020, with no provision for renewal.

For 6 months from the date of entry into force of the Vale Agreement, the Shareholders will be obligated not to transfer, by any means, either directly or indirectly, Vale shares they receive as a result of the implementation of the Proposal (“Lock-Up”), except for (i) the transfer of Vale’s shares by the Shareholders to their affiliates and their current shareholders, provided that such transferred shares shall remain subject to the Lock-Up, and (ii) the transfer of shares not subject to the Vale Agreement held by the Shareholders prior to the Transaction.

Other than as described above and in Item 6 or as set forth in the Shareholders Agreement, neither Valepar nor, to Valepar’s best knowledge, any of the persons listed in Exhibit 1 hereto, currently has any plan or proposal which relates to or would result in any of the transactions described in Item 4 of Schedule 13D.

Item 5.  Interest in Securities of the Issuer.

(b) With respect to any rights or powers to vote, or to direct the vote of, or to dispose of, or direct the disposition of, the Common Shares referenced in paragraph 5(a), there is no shared power to vote, or to direct the vote of, and to dispose of, or to direct the disposition of, such Common Shares.
