On February 9, 2017, Century Aluminum of West Virginia, Inc.
(CAWV), a wholly-owned subsidiary of Century Aluminum Company
(Century), entered into a Settlement Agreement (the Settlement
Agreement) in potential settlement of the previously disclosed
retiree medical class action lawsuit pending before the District
Court for the Southern District of West Virginia. As previously
disclosed, in November 2009 CAWV filed a class action complaint
for declaratory judgment against the United Steel, Paper and
Forestry, Rubber, Manufacturing, Energy, Allied Industrial and
Service Workers International Union (the USW), the USWs local and
certain CAWV retirees, individually and as class representatives
(CAWV Retirees), seeking a declaration of CAWVs rights to
modify/terminate retiree medical benefits. Later in November
2009, the USW and representatives of a retiree class filed a
separate suit against CAWV, Century, Century Aluminum Master
Welfare Benefit Plan, and various John Does with respect to the
foregoing (collectively, the Century Entities). These actions
were consolidated under a lawsuit entitled Dewhurst, et al. v.
Century Aluminum Co., et al., and Century Aluminum of West
Virginia, Inc. v. United Steel, Paper and Forestry, Rubber,
Manufacturing, Energy, Allied Industrial and Service Workers
International Union, AFL-CIO/CLC, et al.

Under the terms of the Settlement Agreement, CAWV has agreed to
make payments into a trust for the benefit of the CAWV Retirees
in the aggregate amount of $23 million over the course of ten
years (the Settlement Amount). The Settlement Amount is payable
in installments with $5 million payable upon final approval by
the court of the Settlement Agreement and $2 million payable
annually thereafter for nine years. It is a condition to the
Settlement Agreement that all class members grant the Century
Entities a full and complete release of all claims that were
asserted or could have been asserted in the lawsuit.

The Settlement Agreement is subject to final court approval
following a notice period during which persons within the class
have the opportunity to object to the settlement or thereafter
appeal such approval. Final court approval is not expected before
the third quarter of 2017.

The Settlement Agreement does not constitute a concession or
admission of wrongdoing or liability by the Century Entities. The
Century Entities have entered into the Settlement Agreement
solely to avoid future inconvenience and protracted, costly
litigation.

A copy of the Settlement Agreement is attached hereto as Exhibit
10.1 to this Current Report on Form 8-K and is incorporated
herein by reference. The description of the Settlement Agreement
is qualified in its entirety by reference to the full text of the
Settlement Agreement.
