We determine if a contract contains a lease at inception. Our material operating leases consist of retail and warehouse locations as well as office space. Our leases generally have remaining terms of 1- 5 years, most of which include options to extend the leases for additional 3 to 5 year periods. Generally, the lease term is the minimum of the noncancelable period of the lease or the lease term inclusive of reasonably certain renewal periods.

Operating lease assets and liabilities are recognized at the lease commencement date. Operating lease liabilities represent the present value of lease payments not yet paid. Operating lease assets represent our right to use an underlying asset and are based upon the operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets. To determine the present value of lease payments not yet paid, we estimate incremental secured borrowing rates corresponding to the maturities of the leases. Our leases typically contain rent escalations over the lease term. We recognize expense for these leases on a straight-line basis over the lease term.

We elected this expedient to account for lease and non-lease components as a single component for our entire population of operating lease assets.

We have elected the short-term lease recognition exemption for all applicable classes of underlying assets. Short-term disclosures include only those leases with a term greater than one month and 12 months or less, and expense is recognized on a straight-line basis over the lease term. Leases with an initial term of 12 months or less, that do not include an option to purchase the underlying asset that we are reasonably certain to exercise, are not recorded on the balance sheet.

Lease expense is recorded within our consolidated statements of operations based upon the nature of the assets. Where assets are used to directly serve our customers, such as facilities dedicated to customer contracts, lease costs are recorded in "cost of sales." Facilities and assets which serve management and support functions are expensed through general and administrative expenses.
