## Note 7 – Pension and Postretirement Benefits 

In the United States, the Company sponsors a defined benefit pen- sion plan that covers approximately 28% of all U.S. employees. In the fourth quarter of 2012, the Company announced that pension eligible employees will no longer earn future benefits in the domestic defined benefit pension plan effective January 1, 2013. The benefits are based on years of service and compensation on a final average pay basis, except for certain hourly employees where benefits are fixed per year of service. This plan is funded with a trustee in respect of past and current service. Charges to expense are based upon costs computed by an independent actuary. The Company’s funding policy is to contribute annually amounts that are allowable for federal or other income tax purposes. These con- tributions are intended to provide for future benefits earned to date. A number of the Company’s non-U.S. subsidiaries sponsor defined benefit pension plans that cover approximately 14% of all non-U.S. employees. The benefits are typically based upon years of service and compensation. These plans are funded with trustees in respect of past and current service. Charges to expense are based upon costs computed by independent actuaries. The Company’s funding policy is to contribute annually amounts that are allowable for tax purposes or mandated by local statutory requirements. These contributions are intended to provide for future benefits earned to date. 

Non-union employees hired after December 31, 2005 are no longer eligible for participation in the ELDEC Corporation (“ELDEC”) and Interpoint Corporation (“Interpoint”) money purchase plan. Qual- ifying employees receive an additional 2% Company contribution to their 401(K) plan accounts. Certain of the Company’s non-U.S. defined benefit pension plans were also amended whereby eligi- bility for new participants will cease. 

Postretirement health care and life insurance benefits are provided for certain employees hired before January 1, 1990, who meet minimum age and service requirements. The Company does not pre-fund these benefits and has the right to modify or terminate the plan. 

A summary of benefit obligations, fair value of plan assets and funded status is as follows:
