Net periodic pension costs are included in cost of sales and SG&A in the accompanying Consolidated and Combined Condensed Statements of Earnings.
Effective December 31, 2015, the Company changed its estimate of the service and interest cost components of net periodic benefit cost for its pension plans. Previously, the Company estimated the service and interest cost components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation. The new estimate utilizes a full yield curve approach in the estimation of these components by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to their underlying projected cash flows. The new estimate provides a more precise measurement of service and interest costs recognized by improving the correlation between projected benefit cash flows and their corresponding spot rates. The change is accounted for as a change in accounting estimate that is inseparable from a change in accounting principle, which is applied prospectively. For 2016, the change in estimate is expected to reduce net periodic pension cost by approximately $1 million when compared to the prior methodology.
Employer Contributions
During 2016, the Company’s cash contribution requirements for its defined benefit pension plans are expected to be approximately $11 million. The ultimate amounts to be contributed depend upon, among other things, legal requirements, underlying asset returns, the plan’s funded status, the anticipated tax deductibility of the contribution, local practices, market conditions, interest rates and other factors.
