Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	COMMITMENTS AND CONTINGENCIES Lease Commitments We are obligated under various operating leases for Shacks and our home office space, expiring in various years through 2031. Under certain of these leases, we are liable for contingent rent based on a percentage of sales in excess of a specified threshold and are responsible for our proportionate share of real estate taxes and utilities. As security under the terms of several of our leases, we are obligated under letters of credit totaling $160 as of July 1, 2015. The letters of credit expire on April 23, 2016 and February 28, 2026. In addition, in December 2013, we entered into an irrevocable standby letter of credit in conjunction with our home office lease in the amount of $80. The letter of credit expires in September 2015 and renews automatically for one-year periods through September 30, 2019. Purchase Commitments Purchase obligations include legally binding contracts, including commitments for the purchase, construction or remodeling of real estate and facilities, firm minimum commitments for inventory purchases, equipment purchases, marketing-related contracts, software acquisition/license commitments and service contracts. These obligations are generally short-term in nature and are recorded as liabilities when the related goods are received or services rendered. We also enter into long-term, exclusive contracts with certain vendors to supply us with food, beverages and paper goods, obligating us to purchase specified quantities. These volume commitments are not subject to any time limit and there are no material financial penalties associated with these agreements in the event of early termination. Legal Contingencies We are subject to various legal proceedings, claims and liabilities, such as employment-related claims and slip and fall cases, which arise in the ordinary course of business and are generally covered by insurance. As of July 1, 2015, the amount of ultimate liability with respect to these matters was not material.
