Amendment No. 3 to Form S-1 Table of Contents AB ACQUISITION LLC AND SUBSIDIARIES Notes to Condensed Consolidated Financial Statements (unaudited) NOTE 7—EMPLOYEE BENEFIT PLANS Pension Plans The Company sponsors a defined benefit pension plan (the "Shaw's Plan") covering union employees under the Shaw's banner. The Company also sponsors a defined benefit pension plan (the "Safeway Plan") for substantially all of its employees under the Safeway banners not participating in multiemployer pension plans. The Company also sponsors a frozen plan covering certain employees under the United banner and a Retirement Restoration Plan that provides death benefits and supplemental income payments for certain senior executives after retirement. The Retirement Restoration Plan is unfunded. The Safeway Plan and the Retirement Restoration Plan were acquired as part of the Safeway acquisition in fiscal 2014. The Company also contributes to various multi-employer pension plans based on obligations arising from most of its collective bargaining agreements. These plans provide retirement benefits to participants based on their service to contributing employers. The Company recognizes expense in connection with these plans as contributions are funded. Other Post-Retirement Benefits In addition to the Company's pension plans, the Company acquired plans as part of the Safeway acquisition that provide post- retirement medical and life insurance benefits to certain employees. Retirees share a portion of the cost of the post-retirement medical plans. The Company pays all the cost of the life insurance plans. The plans are unfunded.
