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 sponsored one nonqualified, unfunded supplemental retirement plan during the six-month period ended June 30, 2011. The Company sponsored two supplemental retirement plans during the six-month period ended June 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):

     During the six-month period ended June 30, 2010, the Company recognized a $1.2 million settlement loss 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 charge was incurred during the six-month period ended June 30, 2011.

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