Pension and Postretirement Benefits:

The Company maintained a frozen qualified defined benefit pension plan for certain of its employees through membership in the Pension Plan for Insurance Organizations (the “Pension Plan”), a multiple-employer trust. The Company has applied a cash balance formula to determine future benefits. Under the cash balance formula, each participant has an account, which is credited annually based on the interest earned on the previous year-end cash balance. The Company also has a frozen non-qualified supplemental cash balance plan (“SERP”) for certain employees. The SERP is funded from the general assets of the Company.

The Company also provides certain healthcare and life insurance benefits to certain qualifying active and retired employees. The Postretirement Health and Life Insurance Plan (the “Postretirement Plan”), which has been frozen, is contributory, requiring participants to pay a stated percentage of the premium for coverage. The components of net periodic (benefit) cost for the three months ended March 31, are summarized below:
