The Company has operating and financing leases for corporate offices, distribution centers, vehicles, and certain equipment. These leases have remaining lease terms of less than 1 year to 12 years and many of the leases have renewal options. Because the Company is not reasonably certain to exercise the renewal options, the options are not considered in determining the lease term, and associated potential option payments are excluded from lease payments and right-of-use calculations. Leases with an initial term of 12 months or less are likewise excluded from right-of-use calculations.

In addition to fixed payments, many of the Company’s lease contracts contain variable payments. Vehicle lease variable payments typically include mileage, and real estate leases include variable charges for taxes and common area maintenance. Variable lease payments and payments for leases with an initial term of 12 months or less are recognized in the period incurred.

As of September 30, 2019, the weighted average remaining lease term for the Company’s operating leases was 5.6 years and for its financing leases was 3.6 years. These leases have weighted average discount rates of 5.8% and 5.2% for operating leases and financing leases, respectively. The rate implicit in the lease is used to discount leases when known. While the implicit rate is often known for finance leases, the Company is generally unable to calculate the implicit rate in operating leases because it does not have access to the lessor’s residual value estimates nor the amount of the lessor’s deferred initial direct costs. When the implicit rate is not known, the Company uses the incremental borrowing rate for secured loans of similar term. The Company uses available data for unsecured loans to borrowers of similar credit to the Company and adjusts the rate to reflect the effect of providing collateral equivalent to the outstanding obligation balance.
