Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsIn October 2020, the Company’s defined benefit pension plan purchased annuities on behalf of certain plan participants currently receiving benefits and offered to make lump-sum payments directly to certain inactive, vested plan participants that are not currently receiving benefit payments and that elect to receive lump-sum payments. The Company anticipates the partial settlement will be completed in the fourth quarter of 2020. Accordingly, the Company estimates that net income for the fourth quarter of 2020 will include an after-tax charge to income ranging from $45.0 million to $55.0 million to recognize the unamortized net unrecognized postretirement benefit costs related to the settled obligations, with a corresponding offset to AOCI.
