CVRD to capture synergies from MBR

Rio de Janeiro, May 2, 2007 — Companhia Vale do Rio Doce (CVRD) signed contracts with its Japanese partners on Empreendimentos Brasileiros de Mineração S. A. (EBM) — Nippon Steel Corporation (NSC), JFE Steel Corporation (JFE), Itochu Corporation (Itochu), Mitsui & Co. Ltd. (Mitsui), Sumitomo Metal Industries Limited (SMI), Sumitomo Corporation (Sumitomo), Marubeni Corporation (Marubeni), Mitsubishi Corporation (Mitsubishi), Kobe Steel Limited (Kobe) and Nisshin Steel Co. Ltd. (Nisshin) — to allow the Company to exploit synergies with its subsidiary Minerações Brasileiras Reunidas S. A. (MBR).

EBM, which is 80% owned by CVRD and 20% by the Japanese partners, has as its main asset a 51% stake in MBR. MBR is controlled by CVRD, which has a 89.8% interest — directly and through its stake in EBM.

MBR produced 64.6 million metric tons (mt) of iron ore in 2006, being the fourth largest producer worldwide. MBR owns world class assets, with proven and probable iron ore reserves of 1.134 billion mt.

CVRD has agreed to buy for US$ 230.8 million the stakes of Mitsui (US$ 114.5 million), SMI (US$ 60.9 million) and Sumitomo (US$ 55.4 million) in EBM. As a result of the acquisition, CVRD will increase its share on EBM’s capital to 86.247% from the current 80%.

Simultaneously, CVRD entered into a usufruct agreement on the EBM shares owned by NSC, JFE, Itochu, Marubeni, Mitsubishi, Kobe and Nisshin, representing 13.753 % of EBM’s total capital. This agreement will transfer to CVRD during the next 30 years all rights and obligations entitled to the EBM shares, including the right to dividends. In exchange, CVRD will pay to the four partners a total of US$ 60.5 million and an annual fee of US$ 48.1 million.

The transactions announced will transfer to CVRD the effective control of 100% of MBR’s total capital for the next 30 years, allowing us to maximize our exposure to one of the best iron ore assets in the world and to exploit synergies mainly derived from the operation of mines, plants and maritime terminals, elimination of redundancies and best practices sharing, and are estimated to reach approximately US$ 500 million, on a net present value basis.

This movement is consistent with CVRD’s strategy of shareholder value creation, in this case through an increased exposure to the global iron ore market, significant cost reduction and efficiency gains.
