PENSIONS AND OTHER POST-RETIREMENT BENEFITS

PENSIONS AND OTHER POST-RETIREMENT BENEFITS

During the nine months endedSeptember 30, 2015, the Company approved amendments to both of the U.S. defined benefit pension plans. These amendments will be effective December 31, 2015. The Company also amended its remaining postretirement medical plan that was effective May 1, 2015. The amendments eliminated the accrual of future benefits for all participants in the defined benefit pension plans and the postretirement medical plan. These amendments resulted in a curtailment gain of approximately $7.1 million. As the plans had unrealized losses in excess of the reduction of the projected benefit obligation at the date of amendment, the gain was recorded as a reduction of the projected benefit obligation and a corresponding reduction of unrealized losses within accumulated other comprehensive loss.

The following tables summarize the costs of the Company’s employee pension and other post-retirement benefit plans for the periods indicated (in thousands):
