Assets held for lease, description			None of the Company’s aircraft held for lease were off lease at December 31, 2020. The Company had nine aircraft that are held for sale as of December 31, 2020: (i) three regional jet aircraft that are on lease and were sold in March 2021; (ii) three off-lease regional jet aircraft; (iii) one off-lease turboprop aircraft and (iv) two turboprop aircraft that are being sold in parts.
Sales-type and finance leases, description		the Company amended the leases for three of its assets that were subject to sales-type leases with two customers. The amendments provided for (i) the exercise of a purchase option of one aircraft to the customer in January 2020, which resulted in a gain of $12,700, (ii) application of collected maintenance reserves and a security deposit held by the Company to past due amounts for the other two aircraft, (iii) payments totaling $585,000 in January 2020 for two of the leases and (iv) the reduction of future payments due under the two finance leases. Because of the uncertainty of collection of amounts receivable under the finance leases, the Company does not recognize interest income on the finance lease receivables (i.e., they are accounted for on a non-accrual basis) and their asset value is based on the collateral value of the aircraft that secure the finance leases, net of projected sales costs. The Company recorded bad debt allowances totaling $1,503,000 related to the two sales-type leases during 2020.
