Our operating leases include Entasis’ facility lease (“Entasis Lease”) consisting of 20,062 square feet of office and laboratory space in Waltham, Massachusetts. In February 2022, Entasis decided to exercise a renewal option for the Entasis Lease to extend the lease term for three additional years through 2025 and subsequently signed the Second Amendment in April 2022. As of March 31, 2022, the weighted average remaining lease term was 3.8 years and the weighted-average incremental borrowing rate used to determine the operating lease right-of-use assets was 7.8%.

We also lease approximately 2,111 square feet of office space in Burlingame, California.

From time to time, the Company is involved in legal proceedings in the ordinary course of its business. Currently, we believe that no litigation or arbitration, either individually or in the aggregate, to which we are presently a party is likely to have a material adverse effect on our operating results or financial position.
