NOTE H – Leases

We have operating leases for offices, warehouses, and certain equipment. Our leases have remaining lease terms of 1 year to 14 years, some of which include options to extend the leases for up to 20 years. We determine if an arrangement is or contains a lease at lease inception. Our leases do not have any residual value guarantees or any restrictions or covenants imposed by lessors. We have lease agreements for real estate with lease and non-lease components, which are accounted for separately.

Certain of our lease agreements for retail stores include variable lease payments, generally based on sales volume. The variable portion of payments are not included in the initial measurement of the right-of-use asset or lease liability due to uncertainty of the payment amount and are recorded as lease expense in the period incurred. Certain of our equipment lease agreements include variable lease costs, generally based on usage of the underlying asset (mileage, fuel, etc.). The variable portion of payments are not included in the initial measurement of the right-of-use asset or lease liability due to uncertainty of the payment amount and are recorded as lease expense in the period incurred.
