Leases
We determine whether an arrangement contains a lease at inception. We have operating leases for office space, apartments, vehicles, and machinery and equipment. Our operating leases have lease terms of less than one year to ten years.
We do not separate lease components (e.g., fixed payments for rent) from non-lease components (e.g., common area maintenance) but account for the non-lease components and non-components (e.g., property taxes and insurance) in a contract as part of the single lease component to which they are related.
The components of lease expense are as follows:
