Defined Benefit Plans
The Company has defined benefit pension and other long-term and postretirement benefit plans covering certain union and non-union employees, primarily in the U.S. and Canada. The defined benefit pension plans are closed to new participants. The liabilities for these plans are calculated using actuarial estimates and management assumptions. These estimates are based on historical information and certain assumptions about future events.
The following tables present the components of net periodic benefit cost of the Company’s plans:
