Employee Benefit Plans

Defined Benefit Pension and Other Postretirement Benefit (OPEB) Plans

We sponsor several defined benefit pension and 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). The U.S. defined benefit pension plans were closed to new entrants and amended to freeze participation and benefit accruals for existing participants effective December 31, 2013. The U.K. plan was closed to new entrants effective December 31, 2002 and was amended to freeze participation for existing participants effective June 30, 2014.

The following tables provide the components of the net periodic benefit cost (credit) for the defined benefit pension and OPEB plans.
