Employee Benefit Plans
EMPLOYEE BENEFIT PLANS
 
Pension and Other Postretirement Plans
 
The Company has funded and non-funded non-contributory defined benefit pension plans, which cover substantially all of its employees. For some employees, benefits are based on final average earnings and length of service, while benefits for other employees are based on an account balance that takes into consideration age, service and earnings during their career.
 
The Company provides certain health care and life insurance benefits for its retired employees, their beneficiaries and covered dependents (“other postretirement benefits”). The health care plan is contributory; the life insurance plan is non-contributory. Substantially all of the Company’s U.S. employees may become eligible to receive other postretirement benefits if they retire after age 55 with at least 10 years of service or under certain circumstances after age 50 with at least 20 years of continuous service.
 
Net periodic (benefit) cost included in “General and administrative expenses” includes the following components:
