Vale comments on the selection process of the Executive Board

Rio de Janeiro, May 19 th  2017 — Vale’s Board of Directors reiterates that the selection process of members of its Executive Board, in particular of its new CEO, Fabio Schvarstman, was safe from any external interference and was conducted in accordance with the best market practices, following the company’s rites and governance. This process resulted in the hiring of a market professional with a reputation entirely formed in private companies.

In the selection process, the Board of Directors set up a committee, formed by representatives of its main controlling shareholders, who was responsible for conducting the process of identifying and selecting the new executive. In the entire process, the committee and the Board itself were supported by the executive recruiting firm Spencer Stuart, a company specializing in recruiting executives with a broad experience and global recognition, providing services for Vale for more than 12 years.

We also inform that, at the last meeting held by the company’s Board of Directors on May 11, the mandates of nearly all of the executive officers were renewed, except for that of Humberto Freitas, who for personal reasons decided to leave the company at the end of his mandate, expected for May 25. No other director was hired.

Vale’s Board of Directors reiterates its commitment with the ethics, transparency and management efficiency in order to meet the interests of shareholders, collaborators, suppliers, clients and communities where the company operates.
