Leases

6 Months Ended

Jun. 30, 2022

The Company accounts for its leases in accordance with ASU No. 2016-02 (Topic 842) which requires that a lessee recognize the assets and liabilities that arise from operating leases. The ASU requires lessees to recognize a liability for lease obligations, which represents the discounted obligation to make future lease payments, and a corresponding right-of-use (ROU) asset on the balance sheet. The Company leases office space facilities and a research and development laboratory under non-cancelable operating leases with varying expirations extending through fiscal year 2028. The lease agreements provide for renewal options and rent escalation over the lease term as well as require the Company to pay maintenance, insurance and property taxes. Lease expense is recognized on a straight-line basis over the term of the lease.
