The Company maintains a qualified defined benefit pension plan (the “Pension Plan”), a nonqualified pension plan and other postretirement benefit plans for certain of its employees.  The net periodic benefit cost is based on estimated values and an extensive use of assumptions about the discount rate, expected return on plan assets, the rate of future compensation increases received by the Company’s employees, mortality, turnover, and medical costs.  The following tables provide the components of net periodic benefit cost:

The Company made cash contributions of $8,937 to its Pension Plan during the first three months of 2014, and intends to make cash contributions of $8,937 to the Pension Plan during the remainder of 2014.  In addition, the Company expects to make cash contributions of $2,763, to the extent allowable for a tax deduction, for the funding of its other postretirement benefit plans during the remainder of 2014.

 

In the first quarter of 2014 the Company offered a one-time voluntary lump sum window to certain eligible terminated vested participants in an effort to reduce its long-term obligations and plan volatility for its Pension Plan.  In May 2014, the Pension Plan paid $11,417 to participants who elected to receive a lump sum distribution, which was funded from the existing Pension Plan assets.   |
