On March 16, 2005, the term of a primary aluminum supply agreement between Century Aluminum of West Virginia, Inc. ("CWV"), a wholly-owned subsidiary of Century Aluminum Company (the "Company"), and Pechiney Rolled Products, LLC ("Pechiney"), a subsidiary of Alcan Inc., was automatically extended through July 31, 2007 when the Public Services Commission of West Virginia ("PSCWV") authorized a new power contract for the Company's Ravenswood, West Virginia production facility. The Molten Aluminum Purchase Agreement, dated as of September 20, 1999, between CWV and Pechiney (the "Pechiney Agreement") was due to expire on December 31, 2005, provided that it would be automatically extended through July 31, 2007 if the power contract for the Ravenswood facility was extended or replaced through that date. CWV currently purchases power used at the Ravenswood facility under a contract with Ohio Power which runs through December 31, 2005. Under the new power contract approved by the PSCWV, Appalachian Power Company will supply power to the Ravenswood facility from January 1, 2006 through December 31, 2010; provided that after December 31, 2007, CWV may terminate the agreement by providing 12-months' notice of termination. Under the terms of the Pechiney Agreement, the Company sells to Pechiney 23 to 27 million pounds per month of the molten aluminum produced at the Ravenswood facility at prices based on the market price for primary aluminum. Pechiney has the right, upon 12 months' notice, to reduce its purchase obligations under the Pechiney Agreement by 50%. Sales of primary aluminum to Pechiney under the Pechiney Agreement represented $249.9 million or 83.0% of the Company's revenues from the Ravenswood facility in 2004.
