Leases [Abstract]
Lessee, Leases [Policy Text Block]	Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. At lease commencement, the Company records a liability for its lease obligation measured at the present value of future lease payments and a right-of-use asset equal to the lease liability adjusted for prepayments and lease incentives. The Company uses its collateralized incremental borrowing rate to calculate the present value of lease liabilities as most of its leases do not provide an implicit rate that is readily determinable. The Company does not recognize a lease obligation and right-of-use asset on its balance sheet for any leases with terms of 12 months or less. Some real estate leases include one or more options to renew or terminate a lease. The exercise of a lease renewal or termination option is assessed at commencement of the lease and only reflected in the lease term if the Company is reasonably certain to exercise the option. The Company has lease agreements that contain both lease and non-lease components, such as common area maintenance fees, and has made a policy election to combine both fixed lease and non-lease components in total gross rent for all of its leases. Expense for operating leases is recognized a straight-line basis over the lease term.
