Leases [Abstract]
Leases	Lease Arrangements The Company has operating and finance leases primarily for its facilities, office space, land, fleet vehicles and equipment. Many of the Company’s leases are non-cancellable and typically have an initial lease term of five to ten years and most provide options at the Company’s election to renew for specified periods of time. The Company’s leases generally provide for fixed annual rentals. Certain of the Company’s leases include provisions for escalating rent, as an example, based on changes in the consumer price index. Variable lease payments based on an index or rate are initially measured using the index or rate in effect at lease commencement. Most of the Company’s leases require it to pay taxes, insurance and maintenance expenses associated with the properties. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company determines if an arrangement contains a lease at inception. The Company has lease agreements with lease and non-lease components, which for all such leases are generally accounted for separately. The Company has elected the short-term lease exception under Topic 842 for all leases and as such, leases with an initial term of 12 months or less are not recorded on the unaudited condensed consolidated balance sheets. The Company recognizes lease expense for short-term leases on a straight-line basis over the lease term. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As the Company’s leases generally do not provide an implicit rate, we use the Company’s incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and any initial direct costs incurred. The Company’s lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.
