Defined Benefit Plan Disclosure [Line Items] |  |
Description of pension plan | During the nine months ended September 30, 2022, the Company amended its qualified pension plan and provided an enhanced benefit for eligible hourly active participants who retire subsequent to April 30, 2022. The amendment required a pension remeasurement. The Company elected the use of a practical expedient to perform the pension remeasurement as of February 28, 2022, the month-end closest to the approval of the plan amendment. The discount rate for the remeasurement was 3.75% compared with 3.23% prior to the remeasurement. The enhanced benefit and remeasurement resulted in higher pension expense for full-year 2022 compared with the initial estimate of the annual pension expense for the qualified plan. |
