Leases

9 Months Ended

Sep. 30, 2020

We lease office space, data centers and office equipment under non-cancelable operating leases with various expiration dates through 2026. In August 2014, we signed a lease for office space in Tysons, Virginia, where we relocated our headquarters to in February 2016. We have subsequently entered into amendments to this lease to provide us with additional office space. In March 2020, we entered into an amendment to the lease for our corporate headquarters, which provides for additional office space, additional parking spaces and additional tenant improvement allowance. The lease term ends in 2026, includes a five-year renewal option and a cumulative tenant improvement allowance of $11.8 million, including $0.7 million tenant improvement allowance within the March 2020 lease amendment.

We did not have any finance leases or subleases as of September 30, 2020 or December 31, 2019. Our lease agreements do not contain any material residual value guarantees, restrictive covenants or variable lease payments. Short-term lease costs were immaterial for the three and nine months ended September 30, 2020 and 2019.
