Postretirement Benefit Plans

NOTE 8. Postretirement Benefit Plans

The Company provides certain health care and life insurance benefits for nine retired employees who have met certain eligibility requirements. All other employees retiring after reaching age 65 and having at least 15 years of service with the Company will be allowed to stay on the Company's group life and health insurance policies, but will be required to pay premiums. The Company's share of the estimated costs that will be paid after retirement is generally being accrued by charges to expense over the employees' active service periods to the dates they are fully eligible for benefits, except that the Company's unfunded cost that existed at January 1, 1993 is being accrued primarily in a straight-line manner that will result in its full accrual by December 31, 2013.

Generally Accepted Accounting Principles ("GAAP") requires the Company to recognize the funded status (i.e. the difference between the fair value of plan assets and the projected benefit obligations) of its postretirement benefit plans in the consolidated balance sheet, with a corresponding adjustment to accumulated other comprehensive income, net of taxes.

Net periodic benefit costs of the postretirement benefit plan were $(1) thousand for the three months ended March 31, 2013 and 2012.
