The Company leases facilities under non-cancellable operating leases primarily in the United States, South Africa, the United Kingdom and Canada. The Company’s operating leases have remaining lease terms of between one to 11 years, some of which include options to extend the leases for up to five years, and some of which include options to terminate the leases within one year. These options to extend the terms of the Company’s operating leases were not deemed to be reasonably certain of exercise as of lease commencement and are therefore not included in the determination of their respective non-cancellable lease terms. The future lease payments due under non-cancellable operating lease arrangements contain fixed rent increases over the term of the lease. The Company also leases office equipment under non-cancellable leases. The Company did not have any subleases as of March 31, 2020.
