Subsequent Events [Abstract]
Subsequent Events	Effective January 1, 2020, the Company reduced both the size of the office space leased and the amount of rent payable in the future. As such, in 2020 the Company will recognize a reduction in both the capitalized amount related to the surrendered office space and a proportionate amount of the liability associated with its future lease obligations. In January 2020, the Company recorded a loss of $160,000 related to the reduction in its ROU Asset, net of the reduction in its operating lease liability, and will recognize amortization of $308,100, $317,600 and $162,600 in 2020, 2021 and the first half of 2022, respectively. In January 2020, the Company amended the leases for three of its assets that are subject to sales-type finance leases. The amendments provided for (i) the sale of one aircraft to the customer in January 2020, (ii) application of collected maintenance reserves and a security deposit held by the Company to past due amounts for the other two aircraft, (iii) required payments totaling $585,000 in January for two of the leases and (iv) reduced the amount of future payments due under the two leases. In January 2020, the lessee for an aircraft leased pursuant to a direct financing lease notified the Company of its intention to exercise the lease-end purchase option for the aircraft in March 2020. In February 2020, the Company and the same lessee agreed to the early exercise of lease-end purchase options for direct financing leases that were to expire in March 2021 and March 2022. All three aircraft were sold to the lessee in March 2020. In March 2019, the Company entered into two interest rate derivative instruments in connection with the MUFG Credit Facility. In March 2020, the counterparties to the MUFG Swaps terminated the MUFG Swaps and the Company became obligated to pay $3.1 million to the counterparties. In January 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus and the risks to the international community as the virus spreads globally (the “COVID-19 Outbreak”). In March 2020, the WHO classified the COVID-19 Outbreak as a pandemic, based on the rapid increase in exposure globally. The ongoing COVID-19 Outbreak has had an overwhelming effect on all forms of transportation globally, but most acutely for the airline industry. The combined effect of fear of infection during air travel and international and domestic travel restrictions has caused a dramatic decrease in passenger loads in all areas of the world, not just in those countries with active clusters of COVID-19, but in airline ticket net bookings (i.e. bookings made less bookings canceled) of flights as well. This has led to significant cash flow issues for airlines, including some of the Company’s customers, and some airlines may be unable to timely meet their obligations under their lease obligations with the Company unless government financial support is received, of which there can be no assurance. Any significant nonpayment or late payment of lease payments by a significant lessee or combination of lessees could in turn impose limits on the Company’s ability to fund its ongoing operations as well as cause new defaults under the Company’s debt obligations, which in turn could lead to an immediate acceleration of debt and foreclosure upon the Company’s assets. Furthermore, for the duration of the pandemic and a period of financial recovery thereafter, sale and acquisition transactions are likely to be curtailed entirely or delayed while the industry returns to financial stability, which could impact the Company’s ability to implement its Recapitalization Plan. No impairments were recorded as of the balance sheet date as no triggering events or changes in circumstances had occurred as of year-end; however, due to significant uncertainty surrounding the situation, management's judgment regarding this could change in the future. In addition, while the Company’s results of operations, cash flows and financial condition could be negatively impacted, the extent of the impact cannot be reasonably estimated at this time. However, as a result of the COVID-19 Outbreak, in March 2020, one of the Company’s customers, which leases two regional jet aircraft subject to Nord Term Loan financing, did not make its quarterly rent payment of approximately $1.4 million. The nonpayment led to a corresponding Nord Term Loan financing payment event of default under the Nord Term Loans for each of those subsidiaries. The Company is currently reviewing its options for remedies against the lessee. It has also entered into negotiations with Nord regarding a workout for the corresponding overdue Nord Term Loan payments. As a result of the non-payment on the two regional jets by the Company’s customer and potential consequent uncertainty concerning future interest payments under the related Nord Term Loans, as well as potential uncertainty related to rent payments and related debt payments on the other three Nord Term Loans, the Company is reevaluating its hedge accounting for the five interest rate derivatives associated with those loans.
