Lessee, Leases [Policy Text Block] | As an accounting policy election, the Company does not apply the recognition requirements of Topic 842 to short-term leases in all of its underlying asset categories. The Company recognizes short-term lease payments in earnings on a straight-line basis over the lease term, and variable lease payments in the period in which the obligation for those payments is incurred.
