Benefit Plans

The Company has a funded defined benefit plan ("Pension Plan") and defined contribution plans, which cover substantially all employees who work 1,000 hours or more in a year. Effective January 1, 2012, the Pension Plan was closed to new participants, with limited exceptions. The Company also has an unfunded defined benefit supplementary retirement plan ("SERP"), which provides benefits, for certain employees, in excess of qualified plan limitations. Effective January 2, 2012, the SERP was closed to new participants. After December 31, 2013, with limited exceptions, employees no longer earn future pension service credits under the Pension Plan and SERP, and retirement benefits attributable to service after that date are provided solely through defined contribution plans.

In addition, certain retired employees currently are provided with specified health care and life insurance benefits ("Postretirement Obligations"). Eligibility requirements for such benefits vary, but generally state that benefits are available to eligible employees who were hired prior to a certain date and retire after a certain age with specified years of service. Certain employees are subject to having such benefits modified or terminated.

Expense related to matching contributions for the 401(k) defined contribution plan amounted to $21 million and $71 million for the 13 and 39 weeks ended November 1, 2014, respectively, and $4 million and $14 million for the 13 and 39 weeks ended November 2, 2013, respectively. The actuarially determined components of the net periodic benefit cost (income) are as follows:
