We sponsor programs that provide retirement benefits to most of our employees. These programs include defined benefit pension plans, defined contribution plans and postretirement healthcare plans. Key terms of our retirement plans are provided in our Annual Report. Our retirement plans costs for the three-month periods ended August 31 were as follows (in millions):

The three-month period ended August 31, 2011 reflects the full restoration on January 1, 2011 of company-matching contributions for our 401(k) plans.
