LEASES

We have entered into operating leases primarily for real estate. The leases have terms which range from 1 year to 18 years, and some include options to renew. Renewal terms are included in the lease term when it is reasonably certain that we will exercise the option to renew.

Operating leases are included in other non-current assets, other current liabilities and other long-term liabilities on the consolidated balance sheets. These assets and liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date, using our incremental borrowing rate because the rate implicit in each lease is not readily determinable. We have certain contracts for real estate that may contain lease and non-lease components which we have elected to treat as a single lease component. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Variable lease expense is recognized in the period in which the obligation for those payments is incurred. Lease expense is reported in rent and purchased transportation on the consolidated statements of income.
