Leases [Abstract]

Lessee, Operating Leases [Text Block]

LeasesAs of December 31, 2022 and 2021, the majority of our operating leases, for which we serve as the lessee, consist primarily of real-estate property for our offices around the world, and we do not have a material amount of finance leases. Both the right-of-use asset and lease liability are measured at the present value of the future lease payments, with the asset being subject to adjustments such as initial direct costs, prepaid lease payments, and lease incentives. Many of our leases provide for renewal and/or termination options, as well as escalation clauses, which are also factored into our lease payments when appropriate. As of December 31, 2022, our leases have remaining lease terms of 1 year to 14 years. The discount rate used to measure the lease

asset and liability is determined at the beginning of the lease term using the rate implicit in the lease, if readily determinable, or using the Company's collateralized credit-adjusted borrowing rate.

The following tables present information on our operating leases for the full years of 2022, 2021 and 2020.
