Subsequent Events [Abstract] |
Subsequent events | Subsequent events We have evaluated all subsequent events through the date the financial statements were issued. See Note 2 Ravenswood impairment for additional information. Century Aluminum announces cost reduction and cash preservation program On August 6, 2015, we announced a cost reduction and cash preservation program in response to weak primary aluminum market conditions. The program includes capacity curtailment; reductions in headcount, operating expenses and capital expenditures; and working capital liquidation. We will continue to explore further cost reduction and cash preservation opportunities. As a result of the cost reduction programs, we expect severance-related charges to be incurred and substantially settled in the second half of 2015.
