The Company has changed the method utilized to estimate the 2016 service cost and interest cost components of net periodic pension cost ("NPPC") for defined benefit pension plans. The more precise application of discount rates for measuring both service costs and interest costs employs yield curve spot rates on a year-by-year expected cash flow basis, using the same yield curves that the Company has previously used. This change in method represented a change in accounting estimate and has been accounted for in the period of change. This change in method decreased the Company's NPPC by approximately
$2 million and approximately $4 million for the three and six months ended June 30, 2016, respectively, compared to what NPPC would have been under the prior method.
