(5) Operating Lease Right-of-Use Asset, Net

In December 2021, we entered into a lease related to a property lease for our laboratory and corporate offices, which expires in January 2027, with an option for us to extend a further 36 months after expiration. Our lease agreements do not contain any material residual guarantees or material restrictive covenants. We determine if an arrangement is a lease at inception by assessing whether it conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

Right-of-use (ROU) assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company’s lease does not provide an implicit rate. We used an adjusted historical incremental borrowing rate, based on the information available at the approximate lease commencement date, to determine the present value of lease payments. Variable rent expense is made up of expenses for common area maintenance and shared utilities and were not included in the determination of the present value of lease payments. We have no finance leases.

Our lease expense was $121,000 for the each of three months ended March 31, 2023 and 2022. The cash paid under the operating lease for base rent for the three months ended March 31, 2023 and 2022 was $118,000 and $97,000, respectively. On March 31, 2023, the weighted average remaining lease term was 3.84 years, and the weighted average discount rate was 10.74%.

Future minimum lease payments under the operating lease as of March 31, 2023 were as follows (in thousands):

Remainder of 2023	$	114
2024		485
2025		499
2026		514

Total undiscounted lease payments	$	1,656
