CENTURY ALUMINUM COMPANYNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(amounts in millions, except share and per share amounts)

Century 401(k) PlansWe sponsor a tax-deferred savings plan under which eligible domestic employees may elect to contribute specified percentages of their compensation with Century. We match a portion of participants' contributions to the savings plan. Employee and matching contributions are considered fully vested immediately upon participation in the plan.
