Accounting Policies [Abstract] |
Principles of consolidation | Principles of consolidation The Company consolidates financial statements of all entities in which the Company has a controlling financial interest, including the accounts of any Variable Interest Entity in which the Company has a controlling financial interest and for which it is the primary beneficiary. All material intercompany balances are eliminated in consolidation.
Segment reporting | Segment reporting The Company’s Chief Operating Decision Maker (“CODM”), the Chief Executive Officer (“CEO”), manages the Company’s business activities as a single operating and reportable segment at the consolidated level. The CODM evaluates the Company’s performance and allocates resources based on its consolidated financial results, as its aircraft leasing, sales, and management operations require centralized oversight of key operational functions. As a single reportable segment entity, the CODM uses consolidated net income attributable to common stockholders to measure segment profit or loss, allocate resources, and assess performance. Significant segment expenses are presented in the Company’s consolidated statements of operations and other comprehensive income/(loss).
Rental of flight equipment/ Net investment in finance or sales-type lease | Rental of flight equipment The Company leases flight equipment principally under operating leases and reports rental income ratably over the life of each lease. Rentals received, but unearned, under the lease agreements are recorded in Rentals received in advance on the Company’s Consolidated Balance Sheets until earned. The difference between the rental income recorded and the cash received under the provisions of the lease is included in Lease receivables, as a component of Other assets on the Company’s Consolidated Balance Sheets. An allowance for doubtful accounts will be recognized for past-due rentals based on management’s assessment of collectability. Management monitors all lessees with past due lease payments and discuss relevant operational and financial issues facing those lessees in order to determine an appropriate allowance for doubtful accounts. In addition, if collection is not reasonably assured, the Company will not recognize rental income for amounts due under the Company’s lease contracts and will recognize revenue for such lessees on a cash basis. All of the Company’s lease agreements are triple net leases whereby the lessee is responsible for all taxes, insurance, and aircraft maintenance. In the future, we may incur repair and maintenance expenses for off-lease aircraft. We recognize repair and maintenance expense in our Consolidated Statements of Operations for all such expenditures. In many operating lease contracts, the lessee is obligated to make periodic payments, which are calculated with reference to the utilization of the airframe, engines, and other major life-limited components during the lease. In these leases, we will make a payment to the lessee to compensate the lessee for the cost of the Qualifying Event incurred, up to the maximum of the amount of Maintenance Reserves payment made by the lessee during the lease term, net of previous reimbursements. These payments are made upon the lessee’s presentation of invoices evidencing the completion of such Qualifying Event. The Company records the portion of Maintenance Reserves that is virtually certain will not be reimbursed to the lessee as Rental of flight equipment revenue. Maintenance Reserves payments which we may be required to reimburse to the lessee are reflected in our overhaul reserve liability, as a component of Security deposits and overhaul reserves on flight equipment leases in our Consolidated Balance Sheets. Any Maintenance Reserves or end of lease payments collected that were not reimbursed to the lessee during the term of the lease for a Qualifying Event are recognized as rental revenues at the end of the lease. Leases that contain provisions which require us to pay a portion of a lessee's major maintenance based on the usage of the aircraft and major life-limited components that were incurred prior to the current lease are recorded as lease incentives based on estimated payments we expect to pay the lessee. These lease incentives are amortized as a reduction of rental revenues over the term of the lease. Lessee-specific modifications are capitalized as initial direct costs and amortized over the term of the lease as a reduction to rental revenue in our Consolidated Statements of Operations. Our performance obligation associated with the sale of flight equipment is satisfied upon delivery of the flight equipment to a customer, which is the point in time where control of the underlying flight equipment has transferred to the buyer. Revenue is recognized when the performance obligation is satisfied and control of the aircraft related to the performance obligation is transferred to the purchaser. Net investment in finance or sales-type lease A net investment in sales-type lease is recognized if a lease meets specific criteria under Accounting Standards Codification (“ASC”) 842 at its inception. Upon commencement of the lease, the book value of the leased asset is de-recognized and a net investment in sales-type lease is recognized within Other assets in our Consolidated Balance Sheets based on the present value of fixed payments under the contract and the residual value of the underlying asset, discounted at the rate implicit in the lease. We recognize the difference between the book value of the aircraft and the net investment in the lease in Aircraft sales, trading, and other in our Consolidated Statement of Operations. Interest income on our net investment in sales-type leases is recognized over the lease term in a manner that produces a constant rate of return on the net investment in the lease.
Initial direct costs | Initial direct costs The Company records as period costs those internal and other costs incurred in connection with identifying, negotiating, and delivering aircraft to the Company's lessees. Amounts paid by us to lessees and/or other parties in connection with originating lease transactions are capitalized as lease incentives and are amortized over the lease term. Additionally, regarding the extension of leases that contain maintenance reserve provisions, the Company considers maintenance reserves that were previously recorded as revenue and no longer meet the virtual certainty criteria as a function of the extended lease term as lease incentives and capitalizes such reserves. The amortization of lease incentives is recorded as a reduction of lease revenue in the Consolidated Statements of Operations.
Cash, cash equivalents and restricted cash | Cash, cash equivalents and restricted cash The Company considers cash and cash equivalents to be cash on hand and highly liquid investments with original maturity dates of 90 days or less. Restricted cash consists of pledged security deposits, maintenance reserves, and rental payments related to secured aircraft financing arrangements.
Flight equipment | Flight equipment Flight equipment under operating lease is stated at cost less accumulated depreciation. Purchases, major additions and modifications, and interest on deposits during the construction phase are capitalized. The Company generally depreciates passenger aircraft on a straight-line basis over a 25-year life from the date of manufacture to a 15% residual value. The Company generally depreciates freighter aircraft on a straight-line basis over a 35-year life from the date of manufacture to a 15% residual value. Changes in the assumption of useful lives or residual values for aircraft could have a significant impact on the Company’s results of operations and financial condition. Major aircraft improvements and modifications incurred during an off-lease period are capitalized and depreciated over the lesser of the remaining life of the flight equipment or the aircraft improvement. In addition, costs paid by us for scheduled maintenance and overhauls are capitalized and depreciated over a period to the next scheduled maintenance or overhaul event. Miscellaneous repairs are expensed when incurred. The Company’s management evaluates on a quarterly basis the need to perform an impairment test whenever facts or circumstances indicate a potential impairment has occurred. An assessment is performed whenever events or changes in circumstances indicate that the carrying amount of an aircraft may not be recoverable. Recoverability of an aircraft’s carrying amount is measured by comparing the carrying amount of the aircraft to future undiscounted net cash flows expected to be generated by the aircraft. The undiscounted cash flows consist of cash flows from currently contracted leases, future projected lease rates, and estimated residual or scrap values for each aircraft. We develop assumptions used in the recoverability analysis based on our knowledge of active lease contracts, current and future expectations of the global demand for a particular aircraft type, potential for alternative use of aircraft and historical experience in the aircraft leasing market and aviation industry, as well as information received from third-party industry sources. The factors considered in estimating the undiscounted cash flows are affected by changes in future periods due to changes in contracted lease rates, economic conditions, technology, and airline demand for a particular aircraft type. In the event that an aircraft does not meet the recoverability test and the aircraft's carrying amount falls below estimated values from third-party industry sources, the aircraft will be recorded at fair value in accordance with the Company’s Fair Value Policy, resulting in an impairment charge. Our Fair Value Policy is described below under “Fair Value Measurements”.
Maintenance Rights | Maintenance Rights The Company identifies, measures, and accounts for maintenance right assets and liabilities associated with its acquisitions of aircraft with in-place leases. A maintenance right asset represents the fair value of the Company’s contractual right under a lease to receive an aircraft in an improved maintenance condition as compared to the maintenance condition on the acquisition date. A maintenance right liability represents the Company’s obligation to pay the lessee for the difference between the lease end contractual maintenance condition of the aircraft and the actual maintenance condition of the aircraft on the acquisition date. The Company’s aircraft are typically subject to triple-net leases pursuant to which the lessee is responsible for maintenance, which is accomplished through one of two types of provisions in its leases: (i) end of lease return conditions (“EOL Leases”) or (ii) periodic maintenance payments (“MR Leases”). (i) EOL Leases Under EOL Leases, the lessee is obligated to comply with certain return conditions which require the lessee to perform maintenance on the aircraft or make cash compensation payments at the end of the lease to bring the aircraft into a specified maintenance condition. Maintenance right assets in EOL Leases represent the difference in value between the contractual right to receive an aircraft in an improved maintenance condition as compared to the maintenance condition on the acquisition date. Maintenance right liabilities exist in EOL Leases if, on the acquisition date, the maintenance condition of the aircraft is greater than the contractual return condition in the lease and the Company is required to pay the lessee in cash for the improved maintenance condition. Maintenance right assets are recorded as a component of Flight equipment subject to operating leases on the Consolidated Balance Sheets. When the Company has recorded maintenance right assets with respect to EOL Leases, the following accounting scenarios exist: (i) the aircraft is returned at lease expiry in the contractually specified maintenance condition without any cash payment to the Company by the lessee, the maintenance right asset is relieved, and an aircraft improvement is recorded to the extent the improvement is substantiated and deemed to meet the Company’s capitalization policy; (ii) the lessee pays the Company cash compensation at lease expiry in excess of the value of the maintenance right asset, the maintenance right asset is relieved, and any excess is recognized as end of lease income; or (iii) the lessee pays the Company cash compensation at lease expiry that is less than the value of the maintenance right asset, the cash is applied to the maintenance right asset, and the balance of such asset is relieved and recorded as an aircraft improvement to the extent the improvement is substantiated and meets the Company’s capitalization policy. Any aircraft improvement will be depreciated over a period to the next scheduled maintenance event in accordance with the Company’s policy with respect to major maintenance and included in Depreciation of flight equipment on the Company’s Consolidated Statements of Operations. When the Company has recorded maintenance right liabilities with respect to EOL Leases, the following accounting scenarios exist: (i) the aircraft is returned at lease expiry in the contractually specified maintenance condition without any cash payment by the Company to the lessee, the maintenance right liability is relieved, and end of lease income is recognized; (ii) the Company pays the lessee cash compensation at lease expiry of less than the value of the maintenance right liability, the maintenance right liability is relieved, and any difference is recognized as end of lease income; or (iii) the Company pays the lessee cash compensation at lease expiry in excess of the value of the maintenance right liability, the maintenance right liability is relieved, and the excess amount is recorded as an aircraft improvement to the extent that it meets our capitalization policy. (ii) MR Leases Under MR Leases, the lessee is required to make periodic payments to us for maintenance based upon planned usage of the aircraft. When a Qualifying Event occurs during the lease term, the Company is required to reimburse the lessee for the costs associated with such an event. At the end of lease, the Company is entitled to retain any cash receipts in excess of the required reimbursements to the lessee. Maintenance right assets in MR Leases represent the right to receive an aircraft in an improved condition relative to the actual condition on the acquisition date. The aircraft is improved by the performance of a Qualifying Event paid for by the lessee who is reimbursed by the Company from the periodic maintenance payments that it receives. Maintenance right assets are recorded as a component of Flight equipment subject to operating leases on the Consolidated Balance Sheets. When the Company has recorded maintenance right assets with respect to MR Leases, the following accounting scenarios exist: (i) the aircraft is returned at lease expiry and no Qualifying Event has been performed by the lessee since the acquisition date, the maintenance right asset is offset by the amount of the associated maintenance payment liability, and any excess is recorded as end of lease income; or (ii) the Company has reimbursed the lessee for the performance of a Qualifying Event, the maintenance right asset is relieved, and an aircraft improvement is recorded to the extent that it meets our capitalization policy. As of December 31, 2024 and 2023, there were no maintenance right liabilities for MR Leases. When flight equipment is sold, maintenance rights are included in the calculation of the disposition gain or loss.
Flight equipment held for sale | Flight equipment held for sale Management evaluates all contemplated aircraft sale transactions to determine whether all the required criteria have been met under Generally Accepted Accounting Principles (“GAAP”) to classify aircraft as flight equipment held for sale. Management uses judgment in evaluating these criteria. Due to the significant uncertainties of potential sale transactions, the held for sale criteria generally will not be met unless the aircraft is subject to a signed sale agreement, or management has made a specific determination and obtained appropriate approvals to sell a particular aircraft or group of aircraft. Aircraft classified as flight equipment held for sale are recognized at the lower of their carrying amount or estimated fair value less estimated costs to sell. At the time aircraft are classified as flight equipment held for sale, depreciation expense is no longer recognized.
Capitalized interest | Capitalized interest The Company may borrow funds to finance deposits on new flight equipment purchases. The Company capitalizes interest expense on such borrowings. The capitalized amount is calculated using our composite borrowing rate and is recorded as an increase to the cost of the flight equipment on our Consolidated Balance Sheets at the time of purchase.
Fair value measurements | Fair value measurements Fair value is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company measures the fair value of certain assets on a non-recurring basis, principally our flight equipment, when GAAP requires the application of fair value, including events or changes in circumstances that indicate that the carrying amounts of assets may not be recoverable. The Company records flight equipment at fair value when we determine the carrying value may not be recoverable. The Company principally uses the income approach to measure the fair value of flight equipment. The income approach is based on the present value of cash flows from contractual lease agreements and projected future lease payments, including contingent rentals, net of expenses, which extend to the end of the aircraft’s economic life in its highest and best use configuration, as well as a disposition value based on expectations of market participants. These valuations are considered Level 3 valuations, as the valuations contain significant non-observable inputs.
Income taxes | Income taxes The Company uses the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred income taxes are recognized for the tax consequences of “temporary differences” by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities. The effect on deferred taxes of a change in the tax rates is recognized in income in the period that includes the enactment date. The Company records a valuation allowance for deferred tax assets when the probability of realization of the full value of the asset is less than 50%. The Company recognizes the impact of a tax position, if that position is more than 50% likely to be sustained on audit, based on the technical merits of the position. Recognized income tax positions are measured at the largest amount that is greater than 50% likely to be realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.
Deferred costs | Deferred costs The Company incurs debt issuance costs in connection with debt financings. Those costs are deferred and amortized over the life of the specific loan using the effective interest method and charged to interest expense. The Company also incurs costs in connection with equity offerings. Such costs are deferred until the equity offering is completed and either netted against the equity raised, or expensed if the equity offering is abandoned.
Aircraft under management | Aircraft under management As of December 31, 2024, the Company manages aircraft across three management platforms: (i) the Blackbird investment funds (ii) the Thunderbolt platform and (iii) on behalf of a financial institution. The Company manages aircraft on behalf of two investment funds, Blackbird Capital I, LLC (“Blackbird I”) and Blackbird Capital II, LLC (“Blackbird II”). The Company owns non-controlling interests in each fund representing 9.5% of the equity of each fund. These investments are accounted for using the equity method of accounting due to the Company’s level of influence and involvement. The investments are recorded at the amount invested net of the Company’s 9.5% share of net income or loss, less any distributions or return of capital received from the entities. Also, the Company manages aircraft that it has sold through its Thunderbolt platform. The Company’s Thunderbolt platform facilitates the sale of mid-life aircraft to investors while allowing the Company to continue the management of these aircraft for a fee. In connection with the sale of aircraft portfolios through the Company’s Thunderbolt platform, the Company has non-controlling interests of approximately 5.0% in two entities. These investments are accounted for using the cost method of accounting and are recorded at the amount invested less any return of capital received from the respective entity. Finally, the Company also manages aircraft for a financial institution for a fee. The Company does not have any equity interest in this financial institution.
Stock-based compensation | Stock-based compensation Stock-based compensation cost is measured at the grant date based on the fair value of the award. Stock-based compensation expense is recognized over the requisite service periods of the awards on a straight-line basis.
Use of estimates | Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Recently issued accounting pronouncements and Recently adopted accounting pronouncements | Recently issued accounting pronouncements In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023-09 Income Taxes (Topic 740) Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The new requirements will be effective for annual periods beginning after December 15, 2024. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. The Company is currently evaluating the impact of ASU 2023-09 on its financial statement disclosures. In November 2024, FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) (“ASU 2024-03”). In January 2025, the FASB issued Clarifying the Effective Date (“ASU 2025-01”) to add some clarity around the effective date of the guidance. ASU 2024-03 requires disaggregated information for specified categories of expenses, including inventory purchases, employee compensation, depreciation, amortization, and depletion, to be presented in certain expense captions on the face of the income statement. The new standard is effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments may be applied either prospectively, to financial statements issued after the effective date, or retrospectively, to all prior periods presented. The Company is currently evaluating the impact of ASU 2024-03 on its financial statement disclosures. Recently adopted accounting pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which requires all public entities, including public entities with a single reportable segment, to provide one or more measures of segment profit or loss used by the chief operating decision maker to allocate resources and assess performance in interim and annual periods. Additionally, the standard requires disclosures of significant segment expenses and other segment items as well as incremental qualitative disclosures. The Company has adopted ASU 2023-07 for our fiscal year 2024 annual financial statements and have applied this standard using the retrospective method. For further information, refer to the Segments section in Note 1 “Summary of Significant Accounting Policies”.
