Operating lease, option to extend	Renewal options are not included in the lease term for automobile and equipment leases because they are not considered reasonably certain of being exercised at lease commencement. Renewal options were not considered for the Company’s corporate headquarters and distribution center lease, which was entered into in 2006 and was for an initial 20-year term.

Operating lease, option to extend	The Company’s store leases typically contain options that permit renewals for additional periods of up to five years each. In general, for store leases with an initial term of 10 years or more, the options to extend are not considered reasonably certain at lease commencement. For stores leases with an initial term of 5 years, the Company evaluates each lease independently and, when the Company considers it reasonably certain that it will exercise an option to extend, the associated payment of that option will be included in the measurement of the right-of-use asset and lease liability
