This press release may contain statements that express management’s expectations about future
events or results rather than historical facts. These forward-looking statements involve risks and
uncertainties that could cause actual results to differ materially from those projected in
forward-looking statements, and CVRD cannot give assurance that such statements will prove correct.
These risks and uncertainties include factors: relating to the Brazilian economy and securities
markets, which exhibit volatility and can be adversely affected by developments in other countries;
relating to the iron ore business and its dependence on the global steel industry, which is
cyclical in nature; and relating to the highly competitive industries in which CVRD operates. For
additional information on factors that could cause CVRD’s actual results to differ from
expectations reflected in forward-looking statements, please see CVRD’s reports filed with the
Brazilian Comissão de Valores Mobiliários and the U.S. Securities and Exchange Commission.
