Our operating leases are comprised of office facilities, with the most significant leases relating to our corporate headquarters in Menlo Park and our office in New York City. Our leases have remaining terms of 1 to 11 years, and many leases include one or more options to renew. We do not assume renewals in our determination of the lease term unless the renewals are deemed to be reasonably assured at lease commencement. We do not have any finance leases.
