During the first quarter of 2017, we made an $80.0 contribution to our U.S. defined benefit pension plan (the “Plan”) using cash on hand and funds borrowed from our former $700.0 revolving credit facility. During 2017, we also began implementing a plan to transition our U.S. employees not covered by a collective bargaining agreement, and our employees covered by a collective bargaining agreement at two of our U.S. facilities, from a defined benefit-based model to a defined contribution structure over a three-year sunset period. These changes caused immaterial remeasurements for the Plan for the affected populations.

Postretirement Healthcare Plans — Net postretirement healthcare costs were $0.1 and $0.1 for the three and six months ended March 31, 2018, and $0.1 and $0.2 for the same periods in the prior year.

Defined Contribution Plans — Expenses related to our defined contribution plans were $2.9 and $5.6 for the three and six months ended March 31, 2018, and $3.1 and $5.7 for the same periods in the prior year.
