Retirement Plans [Abstract]

Retirement Plans

11. Retirement Plans

Certain of the Company’s United States employees participate in a defined-benefit pension plan that closed to new participants effective January 1, 1995. The Company also subsidizes healthcare benefits for eligible retired employees who participate in the pension plan and were hired before January 1, 1992. The Company had one nonqualified, unfunded supplemental retirement plan during the nine-month period ended September 30, 2011. The Company sponsored two supplemental retirement plans during the nine-month period ended September 30, 2010, prior to the termination of one of the supplemental plans in the third quarter of 2010.

The components of periodic benefit costs for the defined-benefit pension, postretirement healthcare and supplemental retirement plan(s) were as follows (in thousands):

	Defined-Benefit Pension Plan Three Months Ended September 30,						Postretirement Healthcare Plan Three Months Ended September 30,				Supplemental Retirement Plan(s) Three Months Ended September 30,

During the nine-month period ended September 30, 2010, the Company recognized a $1.2 million settlement and curtailment loss, primarily as a result of a lump sum distribution paid to a supplemental retirement plan participant which exceeded the service and interest components incurred for that plan. No settlement and curtailment charge was incurred during the nine-month period ended September 30, 2011.

The Company estimates it will contribute $2.2 million to its defined benefit plans during 2011.
