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

Our operating lease related to a property lease for our laboratory and corporate offices expired in December 2021, and we entered into a new lease 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 for the three and six months ended June 30, 2022 was $120,000 and $241,000, respectively. Our lease expense for the three and six months ended June 30, 2021 was $150,000 and $301,000, respectively. The cash paid under the operating lease for base rent for the three and six months ended June 30, 2022 was $76,000 and $173,000, respectively. The cash paid under the operating lease during the three and six months ended June 30, 2021 was $162,000 and $324,000, respectively. On June 30, 2022, the weighted average remaining lease term was 4.59 years, and the weighted average discount rate was 10.74%.
