EMPLOYEE BENEFIT PLANS

The Company has one qualified non-contributory defined benefit pension plan covering a portion of its employees and an unfunded plan that provides benefits in excess of amounts allowable under current tax law in the qualified plan. Both plans are closed to new participants. Effective December 31, 2016, the Company froze benefits for all employees participating in the pension plan. In lieu of the pension plan, the Company provides those employees with an enhanced 401(k) plan match. Employee benefit plan liabilities are calculated using actuarial estimates and management assumptions. These estimates are based on historical information, along with certain assumptions about future events. Changes in assumptions, as well as changes in actual experience, could cause the estimates to change.
