Leases |
Leases | 7. Leases The Company's lease portfolio consists of office space and laboratory facilities. All of the Company's leases are classified as operating leases. The terms of the Company's lease agreements that have commenced currently extend through March 2030 and provide the Company with an option for a five-year extension. Under the terms of the leases, the Company pays base annual rent subject to fixed dollar increases each year and other normal operating expenses such as taxes, repairs, and maintenance. The Company evaluates renewal options at lease inception and on an ongoing basis and considers renewal options that the Company is reasonably certain to exercise in its expected lease terms when classifying leases and measuring lease liabilities in accordance with ASC 842. The leases do not require variable lease payments or residual value guarantees and do not contain restrictive covenants. ​ The leases do not provide an implicit rate, therefore the Company uses its incremental borrowing rate as the discount rate when measuring the operating lease liability. The incremental borrowing rate represents an estimate of the interest rate the Company would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of the lease. Operating lease expense was $1.0 million for the year ended December 31, 2022. Operating cash flows used for operating leases during the year ended December 31, 2022 were $0.9 million. As of December 31, 2022, the weighted-average remaining lease term was 7.25 years, and the weighted average discount rate was 7.46%. Rent expense under operating leases was $1.0 million for the year ended December 31, 2021. As of December 31, 2022, the maturities of the Company’s operating lease liabilities were as follows (in thousands), which are included in Accrued liabilities and other liabilities and Lease liabilities, long term in the accompanying balance sheet:
