Employee Benefit Plans

Defined Benefit Pension and Other Postretirement Benefit Plans

We sponsor several defined benefit pension and other postretirement benefit (OPEB) plans for our employees, including non-qualified pension plans. We maintain a separate defined benefit plan for eligible employees in our U.K. operation (the U.K. plan). During the second quarter of 2013, we amended the U.S. defined benefit pension plans to close the plans to new entrants and to freeze participation and benefit accruals for existing participants effective December 31, 2013. As a result of these plan amendments, we recognized a curtailment loss in the second quarter of 2013, with a corresponding reduction in the prior service cost included in accumulated other comprehensive income. The U.K. plan was closed to new entrants effective December 31, 2002 and was amended in the third quarter of 2013 to freeze participation for existing participants effective June 30, 2014.

The following table provides the components of the net periodic benefit cost for the defined benefit pension and OPEB plans.
