Compensation Discussion and Analysis accruals under the Qualified Plan and are not eligible for the higher matching contribution rate under the Century Aluminum 401(k) Plan. Mr. Gary and Mr. DeZee were each employed by the Company prior to January 1, 2015, and participate in the Qualified Plan, however, only Mr. DeZee is eligible for future accruals under the Qualified Plan.
