EMPLOYEE BENEFIT PLANS

In July 2014, we discontinued our sponsorship of post-65 age healthcare plans, effective January 1, 2015, which resulted in eligible retirees being transitioned to coverage in the individual healthcare insurance market that we subsidize through health reimbursement accounts. In November 2014, a lawsuit was filed challenging certain aspects of this action. In September 2017, we received a favorable ruling related to the lawsuit. During the third quarter of 2017, in connection with the favorable ruling, we reduced our unfunded liability related to postretirement benefits by $26.8. The offset for the reduction of the unfunded liability was recorded to accumulated other comprehensive income and represents unrecognized prior service credits. These unrecognized prior service credits are being recorded to net periodic postretirement benefit (income) expense over a period of approximately eight years. In addition, we remeasured our unfunded liability related to postretirement benefits, which resulted in a gain within net periodic postretirement benefit expense and a reduction of the unfunded liability of $2.6 during the third quarter of 2017.

Net periodic benefit expense (income) for our pension and postretirement plans include the following components:
