Operating Leases

Facility Lease

In March 2015, the Company entered into a 5‑year lease for its corporate headquarters (the ‘‘lease’’). The lease was further amended in February 2018, to add an additional space (the ‘‘expansion space’’) at the current location and to extend the lease term (the ‘‘amended lease’’). The amended lease expires in July 2023. Rent for the facility lease, including the expansion space, increases from $1.4 million per year to $1.7 million per year over the term of the lease. Variable lease payments include the Company’s allocated share of costs incurred and expenditures made by the landlord in the operation and management of the building. The Company has the option to extend the term of the amended lease for one additional term of 5 years commencing after the amended lease expires.
