Leases Leases
Our building leases are comprised of office and laboratory space under non-cancelable operating leases. These lease agreements have remaining lease terms of five years and contain various clauses for renewal at our option. The renewal options were not included in the calculation of the operating lease assets and the operating lease liabilities as the renewal options are not reasonably certain of being exercised. The lease agreements do not contain residual value guarantees.
