Pension Plan

Pension Plan

Park has a noncontributory defined benefit pension plan covering substantially all of its employees. The plan provides benefits based on an employee’s years of service and compensation.

Park generally contributes annually an amount that can be deducted for federal income tax purposes using a different actuarial cost method and different assumptions from those used for financial reporting purposes. There were no pension plan contributions for the three-month periods ended March 31, 2015 and 2014.

The following table shows the components of net periodic benefit (income) expense:
