ITEM 2.     ACQUISITION OR DISPOSITION OF ASSETS.

            On April 7, 2000, Century Aluminum Company, a Delaware corporation
("Century"), through its wholly-owned indirect subsidiary Berkeley Aluminum,
Inc., a Delaware corporation ("Berkeley"), increased its 26.67% undivided
interest in certain property, plant and equipment which comprise an aluminum
reduction facility in Mt. Holly, South Carolina (the "Mt. Holly Facility") to
49.67% by purchasing a 23% undivided interest from Xstrata Aluminum Corporation,
a Delaware corporation ("Xstrata"). Xstrata is a wholly-owned subsidiary of
Xstrata AG, a publicly traded Swiss company ("Xstrata AG"). Glencore
International AG (Glencore) is a major shareholder of Xstrata AG and is also a
major shareholder of Century. As part of the purchase, Berkeley also acquired
Xstrata's 23% interest in the general partnership which operates and maintains
the Mt. Holly Facility (the "Operating Partnership", and together with the Mt.
Holly Facility, the "Mt. Holly Assets"). Prior to Berkeley's purchase of the Mt.
Holly Assets, it held a 26.67% undivided interest in the Mt. Holly Facility and
a 26.67% interest in the Operating Partnership.

            The sale was completed pursuant to an Asset Purchase Agreement dated
as of March 31, 2000 (the "Purchase Agreement") by and between Berkeley and
Xstrata. The aggregate purchase price for the Mt. Holly Assets was $95 million,
subject to certain post-closing adjustments. Under the terms of the Purchase
Agreement, Berkeley agreed to assume certain of Xstrata's obligations and
liabilities relating to the Mt. Holly Assets. The terms of the Purchase
Agreement were determined through arms'-length negotiations between the parties.
Berkeley paid the purchase paid using available cash.

            The Mt. Holly Facility has the capacity to produce up to 480
million pounds of primary aluminum per year. Century's 49.47% ownership
represents 238.4 million pounds of this capacity.
