Benefit Plans Benefit Plans
We have a non-contributory defined benefit pension plan, as well as a supplemental executive retirement plan that covered eligible employees through December 31, 2022. Effective January 1, 2023, these plans were frozen (no future benefits will be accrued for participants due to employment and no new participants will be added). Participants in these plans were fully vested in their benefits as of December 31, 2022. We also offer benefits for retired domestic employees and their eligible spouses and dependents under a postretirement benefit plan. Participation in this plan is limited to eligible employees that participated in the defined benefit pension plan.
Table 10.1 and 10.2 provide the components of net periodic benefit cost for our pension, supplemental executive retirement and other postretirement benefit plans for the three and six months ended June 30, 2026 and 2025.
