(15) Retirement Benefits
The principal retirement plan for employees is the Walgreen Profit-Sharing Retirement Trust, to which both the Company and participating employees contribute. The Company's contribution, which has historically related to FIFO earnings before interest and taxes and a portion of which is in the form of a guaranteed match, is determined annually at the discretion of the Board of Directors. The profit-sharing provision was $342 million in fiscal 2013, $283 million in fiscal 2012 and $382 million in fiscal 2011. The Company's contributions were $262 million in fiscal 2013, $372 million in fiscal 2012 and $322 million in fiscal 2011.
The Company provides certain health insurance benefits for retired employees who meet eligibility requirements, including age, years of service and date of hire. The costs of these benefits are accrued over the service life of the employee. In fiscal 2012, the Company amended its prescription drug program for certain Medicare-eligible retirees to a group-based Company-sponsored Medicare Part D program, or employer group waiver program, effective January 1, 2013. The Company's postretirement health benefit plan is not funded.

The discount rate assumption used to compute the postretirement benefit obligation at year-end was 5.20% for 2013 and 4.15% for 2012.

The consumer price index assumption used to compute the postretirement benefit obligation was 2.00% for 2013 and 2012.
Future benefit costs were estimated assuming medical costs would increase at a 7.00% annual rate, gradually decreasing to 5.25% over the next nine years and then remaining at a 5.25% annual growth rate thereafter. A one percentage point change in the assumed medical cost trend rate would have the following effects (in millions):
