Retirement Benefits [Abstract]  
RETIREMENT AND DEFERRED COMPENSATION PLANS RETIREMENT AND DEFERRED COMPENSATION PLANS
We have various noncontributory retirement plans covering certain of our domestic and foreign employees. Benefits under our retirement plans are based on participants’ years of service and annual compensation as defined by each plan. Annual cash contributions to fund pension costs accrued under our domestic plans are generally at least equal to the minimum funding amounts required by the Employee Retirement Income Security Act of 1974, as amended (“ERISA”). Certain pension commitments under our foreign plans are also funded according to local requirements or at our discretion.
Effective January 1, 2021, our domestic noncontributory retirement plans were closed to new employees and employees who were rehired after December 31, 2020. These employees are instead eligible for additional contribution to their defined contribution 401(k) employee savings plan. All domestic employees with hire/rehire dates prior to January 1, 2021 are still eligible for the domestic pension plans and continue to accrue plan benefits after this date.
