Description of lease arrangements	We lease the majority of our retail sporting goods stores under non-cancelable operating leases. The leases typically provide for terms of five to ten years with options to extend at our discretion. Many of our leases contain scheduled increases in annual rent payments and the majority of our leases also require us to pay maintenance, insurance and real estate taxes. Additionally, many of the lease agreements contain tenant improvement allowances, rent holidays and/or rent escalation clauses (contingent rentals) based on net sales for the location. For purposes of recognizing incentives and minimum rental expenses on a straight-line basis over the terms of the leases, we use the date of initial possession to begin amortization, which is generally when we enter the space and begin to make improvements in preparation of our intended use.
