Retirement Benefits [Abstract] |
Retirement Plans | Retirement Plans DC Plans Domestic and international DC plans are available to eligible salaried and craft employees. Company contributions to DC plans are based on an employee's eligible compensation and participation rate. We recognized expense of $143 million in 2023 and $129 million in both 2022 and 2021. DB Plans We have no material DB plans. During 2022, we recognized a $42 million gain on pension settlement upon the completion of compensation and other items associated with our largest DB plan, which provided retirement benefits to certain employees in the Netherlands, which was terminated in December 2021. The loss on termination of the plan of $198 million in 2021 consisted primarily of unrecognized actuarial losses included in AOCI and did not impact our cash position. Multiemployer Pension Plans We participate in multiemployer pension plans for unionized construction and maintenance craft employees. Company contributions are based on the hours worked by employees covered under various collective bargaining agreements and totaled $75 million, $51 million and $44 million during 2023, 2022 and 2021, respectively. Upon withdrawal from a multiemployer plan, we may have an obligation to make additional contributions for our share of any unfunded benefit obligation, but only if we do not meet the requirements of any applicable exemptions. We participate in a multiemployer plan in which we are aware of a significant unfunded benefit obligation. However, we believe we qualify for an exemption and do not believe we have a probable payment to the plan. Therefore, we have not recognized a liability related to this unfunded benefit obligation. The preceding information does not include amounts related to benefit plans applicable to employees associated with certain contracts with the U.S. Department of Energy because we are not responsible for the current or future funding of these plans.
