Lessee Lease Description [Line Items]    
Operating lease, option to extend Our leases have remaining lease terms of 1 year to 11 years. These leases generally contain renewal options for periods ranging from two to five years. Because the Company is not reasonably certain to exercise these renewal options, the options are not considered in determining the lease term, and associated potential option payments are excluded from lease payments.
