Retirement Benefits [Abstract] |
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. The components of the employee benefit plans expense consisted of the following:

We contributed $0.9 million to fund current benefit payments for our SERPs and $13.8 million for our defined benefit pension plan during the nine months ended September 30, 2019. During the remainder of 2019, we anticipate contributing an additional $0.3 million to fund the SERPs' benefit payments and an additional $4.8 million to fund our qualified defined benefit pension plan. In the third quarter of 2018, we recognized a $2.0 million settlement charge related to lump-sum distributions from our SERP. Settlement charges are recorded when total lump-sum distributions for a plan's year exceed the total projected service cost and interest cost for that plan year.
