Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Litigation In the normal course of our business, various claims and lawsuits have been filed or are pending against us. Most of these claims and lawsuits are covered by insurance and the maximum amount of our liability, net of any insurance recoverables, is typically limited to our self-insurance retention levels. We believe the ultimate outcome of these claims and lawsuits will not have a material impact on our consolidated financial statements. Contingent Obligation – Lease Out and Lease Back Type Transaction At August 31, 2017, we had an estimated contingent obligation of $122 million. At the inception of the lease, we paid the aggregate of the net present value of the obligation to a group of major financial institutions, who agreed to act as payment undertakers and directly pay this obligation. As a result, this contingent obligation is considered extinguished and neither the funds nor the contingent obligation have been included in our Consolidated Balance Sheets. In January 2016, we exercised our option to terminate, at no cost, this transaction as of January 2, 2018. Contingent Obligations – Indemnifications Some of the debt contracts we enter into include indemnification provisions obligating us to make payments to the counterparty if certain events occur. These contingencies generally relate to changes in taxes or changes in laws which increase our lender’s costs. There are no stated or notional amounts included in the indemnification clauses, and we are not able to estimate the maximum potential amount of future payments, if any, under these indemnification clauses.

Litigation

In the normal course of our business, various claims and lawsuits have been filed or are pending against us. Most of these claims and lawsuits are covered by insurance and the maximum amount of our liability, net of any insurance recoverables, is typically limited to our self-insurance retention levels.
