Press Release
Vale on the effects of currency volatility
Rio de Janeiro, September 26, 2008 Companhia Vale do Rio Doce (Vale) in response to market
comments clarifies some issues related to the recent depreciation of the Brazilian real against the
US dollar:
(a) Most of Vales revenues, approximately 95%, are denominated in US dollars (USD), whereas, in
average, 60% of its operational costs and investment costs are denominated in Brazilian reais
(BRL), and the remaining in other currencies: USD, Canadian dollars, Indonesian rupiahs, Australian
dollars and euros. In addition, Vale has assets denominated in currencies other than the BRL;
(b) Vale definitively denies that it has realized losses derived from the BRL/USD exchange rate
volatility;
(c) Vale uses exchange rate swaps to convert the part of its debt, which is denominated in BRL, to
USD. As a consequence, 99% of its debt denominated is denominated in USD, consistently with its
revenues composition by currency;
(d) Vales exchange rate swaps transactions have long term maturities and have no margin calls
clauses;
(e) Vale has a conservative financial policy, using only plain vanilla non-levered instruments
for hedging, and has an effective control of their use;
(f) Vales risk management policy, approved by the Board of Directors, explicitly forbids
directional bets and speculative transactions with derivatives, and the compliance with these rules
is rigorously controlled;
(g) In its quarterly earnings releases, Vale provides a detailed report of the results with
transactions involving derivatives, making it clear their non-cash and cash impact on its short
term performance, as well as those derived from monetary variation of other items of its balance
sheet.

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