Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	15. Commitments and Contingencies Litigation The Company is involved in various legal proceedings and has certain unresolved claims pending. Based on the information currently available, management believes that all claims currently pending are either covered by insurance or would not have a material adverse effect on the Company's business, operating results or financial condition. Lease Commitments The Company has obligations under various lease agreements with third-party lessors related to the real estate for certain Company Drive-In operations that were sold to franchisees. Under these agreements, which expire through 2024, the Company remains secondarily liable for the lease payments for which it was responsible as the original lessee. As of August 31, 2012, the amount remaining under these guaranteed lease obligations totaled $8.0 million. At this time, the Company does not anticipate any material defaults under the foregoing leases; therefore, no liability has been provided. In addition, capital lease obligations totaling $1.1 million are still reflected as liabilities as of August 31, 2012 for properties sold to franchisees and for which the Company remains secondarily liable through 2021. At this time, the Company also does not anticipate any material defaults under these leases. Purchase Obligations At August 31, 2012, the Company had purchase obligations of approximately $77 million which primarily related to its estimated share of system-wide commitments for food products.
