Pension and Postretirement Benefits [Abstract]

PENSION AND POSTRETIREMENT BENEFITS

13. PENSION AND POSTRETIREMENT BENEFITS

We have defined benefit retirement plans (“plans”) for eligible salaried and hourly employees. Benefits are based on years of credited service and average compensation or stated amounts for each year of service. We also sponsor postretirement plans which provide certain medical and dental benefits (“other postretirement benefits”) to qualifying U.S. employees.

Components of pension benefit and other postretirement benefit costs included:

During the first quarter of fiscal 2012, we contributed $3.0 million to our pension plans and contributed $7.5 million to our other postretirement plans. Based upon the current funded status of the plans and the current interest rate environment, we anticipate making further contributions of approximately $79.2 million to our pension plans for the remainder of fiscal 2012. We anticipate making further contributions of $21.0 million to our other postretirement plans during the remainder of fiscal 2012. These estimates are based on current tax laws, plan asset performance, and liability assumptions, which are subject to change.
