Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract] |
EMPLOYEE BENEFIT PLANS | EMPLOYEE BENEFIT PLANS We have one qualified non-contributory defined benefit pension plan covering a portion of our employees and an unfunded plan that provides benefits in excess of amounts allowable under current tax law in the qualified plans. We closed enrollment in the pension plans to salaried employees hired after December 31, 2005. Effective December 31, 2016, we froze benefits for all employees participating in the pension plan. In lieu of the pension plan, we provide those employees with an enhanced 401(k) plan match similar to what is currently provided to employees hired after December 31, 2005. 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. We are not required to make mandatory 2022 pension contributions due to our plan’s improved funding status and have made no pension contribution payments during the three months ended March 31, 2022. The net pension and postretirement benefit (credits) costs that have been recorded are shown in the following table:
