Pension and Other Post-Retirement Benefit Plans

We sponsor pension plans that cover certain hourly and salaried employees in the United States and United Kingdom. Each of the plans are frozen to new participants. Our policy is to make annual contributions to the plans to fund the normal cost as required by local regulations. In addition, we have a post-retirement benefit plan for certain U.S. operations, retirees and their dependents.

The components of net periodic (benefit) cost related to pension and other post-retirement benefit plans is as follows:
