Pension and Other Postretirement Benefits

Note 6—Pension and Other Postretirement Benefits

The Company sponsors various qualified and non-qualified defined benefit pension and other postretirement benefit plans that provide for retirement and medical benefits for substantially all employees residing in the United States. The Company also sponsors other pension benefit plans that provide benefits for internationally-based employees at certain non-U.S. locations, which are not presented below as they are not material.

In October 2015, the Company's board of directors approved an amendment of the qualified defined benefit pension plan such that the Company discontinued employer provided credits after December 31, 2015. Plan participants continue to earn interest credits on existing balances at the time of the freeze. As a result, a curtailment gain totaling $8 million was recognized as part of the Company's net periodic benefit cost. The Company also recorded a net unrealized actuarial gain of $56 million from the remeasurement of its pension plan in the first quarter of fiscal 2016 within other comprehensive income.

The components of net periodic benefit cost are as follows:

	Pension Benefits						Other Postretirement Benefits
