Effective as of the beginning of 2016, we prospectively changed the method we use to estimate the service and interest cost components of pension and retiree medical expense. The pre-tax reduction in net periodic benefit cost associated with this change in the 12 and 36 weeks ended September 3, 2016 was $29 million ($19 million after-tax or $0.01 per share) and $86 million ($56 million after-tax or $0.04 per share), respectively. See “Pension and Retiree Medical Plans” in “Our Critical Accounting Policies” in Management’s Discussion and Analysis of Financial Condition and Results of Operations for further unaudited information on this change in accounting estimate.

The components of net periodic benefit cost for pension and retiree medical plans are as follows:
