We have operating leases primarily for office space, temporary residences, automobiles and office equipment. Contracts containing assets that we benefit from and control are recognized on our balance sheet. Leases with an initial term of 12 months or less are not recorded on the balance sheet. We recognize lease expense for these leases on a straight-line basis over the lease term. We combine the lease and non-lease components for all of our lease agreements.

Certain leases include one or more options to renew, with renewal terms that can extend the lease term from one to ten years. The exercise of lease renewal options is at our sole discretion, and lease renewal options are not included in our lease terms if they are not reasonably certain to be exercised. Our lease agreements do not contain any residual value guarantees or restrictive covenants or options to purchase the leased property.

We used the incremental borrowing rate on January 1, 2019 for operating leases that began prior to that date.
