NOTE 8.          LEASES

The Company leases certain buildings, vehicles, and equipment in order to reduce the risk associated with ownership. The Company elected the practical expedient permitted under ASC 842 not to include short-term leases with a duration of 12 months or less on the balance sheet. As of March 31, 2019 and December 31, 2018, all leases were classified as operating leases. Building leases generally carry terms of 5 to 10 years with annual rent escalations at fixed amounts per the lease. Vehicle leases generally carry a fixed term of one year with renewal options to extend the lease on a monthly basis resulting in lease terms up to 5 years depending on the class of vehicle. The exercise of renewal options is at the Company’s sole discretion. It is reasonably certain that the Company will exercise the renewal options on its vehicle leases. The measurement of right-of-use assets and liabilities for vehicle leases includes the fixed payments associated with such renewal periods. We separate lease and nonlease components of contracts. Our lease agreements do not contain any material variable payments, residual value guarantees, early termination penalties or restrictive covenants.

The Company uses the rate implicit in the lease when available; however, most of our leases do not provide a readily determinable implicit rate. Accordingly, we estimate our incremental borrowing rate based on information available at lease commencement.
