Employee Benefit Plans Employee Benefit Plans
We sponsor a noncontributory defined benefit pension plan and non-qualified Supplemental Executive Retirement Plans ("SERPs"). The accrual for future benefits has been frozen in our defined benefit pension plan and SERPs.

We sponsor a defined contribution plan covering substantially all non-union and certain union employees. We match a portion of employees' voluntary contributions to this plan.
Other union-represented employees are covered by defined benefit pension plans jointly sponsored by us and the union, or by union-sponsored multi-employer plans.
The components of the employee benefit plan expense consisted of the following:

We contributed $0.6 million to fund current benefit payments for our SERPs during the six months ended June 30, 2025. During the remainder of 2025, we anticipate contributing an additional $1.0 million to fund the SERPs' benefit payments. We have met regulatory funding requirements for our qualified benefit pension plan and do not have a mandatory contribution in 2025.
