Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract] |
Employee Benefit Plans | 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. Currently, the pension plan is closed to new participants. 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. In 2016, the Company has no mandatory pension contribution requirement. The net pension and postretirement benefit costs that have been recorded are shown in the following table:
