10.         Lease Obligations

The San Rafael Lease constitutes an operating lease under ASC 842 and the Company estimates the lease term as July 2022 through October 2026. The option to extend for a three-year period lacks significant economic incentives and disincentives, which would make exercise reasonably certain. Fixed lease payments for identified lease components over the identified term were discounted at the Company's estimated incremental borrowing rate as of the date of contract execution and are reflected in the condensed consolidated balance sheets under the captions Lease liabilities, current and Lease liabilities, and the corresponding right of use asset is reflected in the condensed consolidated balance sheets under the caption Right-of-use assets. Non-lease components, such as common area maintenance costs, are excluded from the lease liability calculation and expensed as incurred. The Company records a straight-line monthly rent expense for the San Rafael Lease equal to the sum of all fixed lease payments divided by the number of months in the lease term.
