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:

Additionally, during the remainder of 2026, we have required pension plan contributions totaling $4.7 million.
