At the inception of an arrangement, the Company determines if an arrangement is, or contains, a lease based on facts and circumstances present in that arrangement. Lease classifications, recognition, and measurement are then determined at the lease commencement date.

The Company’s operating lease ROU assets and operating lease liabilities represent primarily leases for office spaces used to conduct our business. These leases have remaining terms of approximately 5 to 11 years which include one or more options to renew, with renewal terms from 3 years to 8 years. Based on the Company’s reasonable certainty to exercise these renewal options, the renewal to extend the lease terms are included in valuing our ROU assets and liabilities. As most of our operating leases do not provide an implicit rate, the Company uses its incremental borrowing rate as the discount rate when determining the present value of the lease payments. The incremental borrowing rate is determined based on the Company’s secured borrowing rate, lease terms and current economic environment. Some of our operating leases include both lease (rent payments) and non-lease components (maintenance costs such as cleaning and landscaping services). The Company has elected the practical expedient to account for lease component and non-lease component as a single component for all leases. Lease expense for operating leases is recognized on a straight-line basis over the lease term.

Finance leases primarily consist of processing and lab equipment for our facilities. The Company’s finance leases generally have terms between two to three years and some of the leases include options to purchase the underlying assets at fair market value at the conclusion of the lease term. At March 31, 2019, assets recorded under finance leases were $655,000 less accumulated depreciation of $18,000, resulting in net fixed assets under finance leases of $637,000, which is recorded within net property and equipment on the Consolidated Balance Sheets.

The Company adopted the policy to not recognize ROU assets and liabilities for short term leases.
