NOTE
7
- PENSION AND OTHER POSTRETIREMENT BENEFITS
 
The Company sponsors a defined benefit pension plan (“Plan”) covering certain domestic employees. Benefits are based on each covered employee’s years of service and compensation. The Plan is funded in conformity with the funding requirements of applicable U.S. regulations. The Plan was closed to new participants effective
January 
1,
2008.
Employees hired after this date, in eligible locations, participate in an enhanced
401
(k) plan instead of the defined benefit pension plan. Employees hired prior to this date continue to accrue benefits.
 
Additionally, the Company sponsors defined contribution pension plans made available to all domestic and Canadian employees. The Company funds the cost of these benefits as incurred.
 
The Company also sponsors a non-contributory defined benefit postretirement health care plan that provides health benefits to certain domestic and Canadian retirees and eligible spouses and dependent children. The Company funds the cost of these benefits as incurred.
