Remeasurement of Qualified Pension Plans

In June 2015, we made a $200.0 million voluntary contribution to fund our qualified pension plans. We also elected to perform an interim remeasurement of our plan obligations and assets as of June 26, 2015. The discount rate used to determine the pension obligation was 4.8%. All other actuarial assumptions used for the remeasurement were consistent with those used at the end of 2014. The remeasurement resulted in a decrease to the pension obligation of $76.1 million with a corresponding decrease to accumulated other comprehensive loss, net of tax. Net periodic pension cost is expected to be $8.5 million for the remainder of 2015.
