Principles of Consolidation—We consolidate all entities in which we have a controlling financial interest and control over significant operating decisions, as well as variable interest entities (“VIEs”) in which we are the primary beneficiary. All intercompany transactions and balances have been eliminated. The ownership interest of other investors in consolidated subsidiaries is recorded as non-controlling interest.

We use the equity method of accounting for investments in entities in which we exercise significant influence, but which do not meet the requirements for consolidation. Under the equity method, we record our proportionate share of the underlying net income (loss) of these entities as well as the proportionate interest in adjustments to other comprehensive income (loss).

Use of Estimates—The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Risks and Uncertainties—In the normal course of business, we encounter several significant types of economic risk including credit, market, and capital market risks. Credit risk is the risk of the inability or unwillingness of a lessee, customer, or derivative counterparty to make contractually required payments or to fulfill its other contractual obligations. Market risk reflects the risk of a downturn or volatility in the underlying industry segments in which we operate, which could adversely impact the pricing of the services offered by us or a lessee’s or customer’s ability to make payments, increase the risk of unscheduled lease terminations and depress lease rates and the value of our leasing equipment or operating assets. Capital market risk is the risk that we are unable to obtain capital at reasonable rates to fund the growth of our business or to refinance existing debt facilities. We, through our subsidiaries, also conduct operations outside of the United States; such international operations are subject to the same risks as those associated with our United States operations as well as additional risks, including unexpected changes in regulatory requirements, heightened risk of political and economic instability, potentially adverse tax consequences and the burden of complying with foreign laws. We do not have significant exposure to foreign currency risk as all of our leasing arrangements are denominated in U.S. dollars.

Property, Plant and Equipment, Leasing Equipment and Depreciation—Property, plant and equipment and leasing equipment are stated at cost (inclusive of capitalized acquisition costs, where applicable) and depreciated using the straight-line method, over estimated useful lives, to estimated residual values which are summarized as follows:

Asset

Range of Estimated Useful Lives

Residual Value Estimates

Aircraft

25 years from date of manufacture

Generally not to exceed 15% of manufacturer’s list price when new

Aircraft engines

2 - 6 years, based on maintenance adjusted service life

Sum of engine core salvage value plus the estimated fair value of life limited parts

Aviation tooling and equipment

3 - 6 years from date of purchase

Scrap value at end of useful life

Offshore energy vessels

25 years from date of manufacture

10% of new build cost

Furniture and fixtures

3 - 6 years from date of purchase

None

Computer hardware and software

2 - 5 years from date of purchase

None

Construction in progress

N/A

Major improvements and modifications incurred in connection with the acquisition of property, plant and equipment and leasing equipment that are required to get the asset ready for initial service are capitalized and depreciated over the remaining life of the asset. Project costs of major additions and betterments, including capitalizable engineering costs and other costs directly related to the development or construction of project, are capitalized and depreciation commences once it is placed into service. Interest costs directly related to and incurred during the construction period of property, plant and equipment are capitalized.

For planned major maintenance or component overhaul activities for aviation equipment off lease, the cost of such major maintenance or component overhaul event is capitalized and depreciated on a straight-line basis over the period until the next maintenance or component overhaul event is required.

Our offshore energy vessels are required to be drydocked periodically for recertifications or major repairs and maintenance that cannot be performed while the vessels are operating. Normal repairs and maintenance are expensed as incurred. We capitalize the costs associated with the drydockings and amortize them on a straight-line basis over the period between drydockings, usually during a 60 month time span.

In accounting for leasing equipment, we make estimates about the expected useful lives, residual values and the fair value of acquired in-place leases and acquired maintenance liabilities (for aviation equipment). In making these estimates, we rely upon observable market data for the same or similar types of equipment and, in the case of aviation equipment, our own estimates with respect to a lessee’s anticipated utilization of the aircraft or engine. When we acquire leasing equipment subject to an in-place lease, determining the fair value of the in-place lease requires us to make assumptions regarding the current fair values of leases for identical or similar equipment, in order to determine if the in-place lease is within a fair value range of current lease rates. If a lease is below or above the range of current lease rates, the resulting lease discount or premium is recognized as a lease intangible and amortized into lease income over the remaining term of the lease.

Capitalized Interest—The interest cost associated with major development and construction projects are capitalized and included in the cost of the project. Interest capitalization ceases once a project is substantially complete or no longer undergoing construction activities to prepare it for its intended use. We capitalized interest of $2.7 million, $2.4 million and $1.0 million during the years ended December 31, 2022, 2021 and 2020, respectively.

Repairs and Maintenance—Repair and maintenance costs that do not extend the lives of the assets are expensed as incurred. Our repairs and maintenance expense was $7.2 million, $3.2 million and $1.3 million during the years ended December 31, 2022, 2021 and 2020, respectively, and are included in Operating expenses in the Consolidated Statements of Operations.

Impairment of Long-Lived Assets—We perform a recoverability assessment of each of our long-lived assets whenever events or changes in circumstances, or indicators, indicate that the carrying amount or net book value of an asset may not be recoverable. Indicators may include, but are not limited to, a significant lease restructuring or early lease termination; significant traffic decline; a significant change in market conditions; or the introduction of newer technology aircraft, vessels or engines. When performing a recoverability assessment, we measure whether the estimated future undiscounted net cash flows expected to be generated by the asset exceeds its net book value. The undiscounted cash flows consist of cash flows from currently contracted leases and contracts, future projected leases, transition costs, estimated down time and estimated residual or scrap values. In the event that an asset does not meet the recoverability test, the carrying value of the asset will be adjusted to fair value resulting in an impairment charge.

Management develops the assumptions used in the recoverability analysis based on its knowledge of active contracts, current and future expectations of the global demand for a particular asset and historical experience in the leasing markets, as well as information received from third party industry sources. The factors considered in estimating the undiscounted cash flows are impacted by changes in future periods due to changes in contracted lease rates, residual values, economic conditions, technology, demand for a particular asset type and other factors.

Maintenance Payments—Typically, under an operating lease of aircraft, the lessee is responsible for performing all maintenance and is generally required to make maintenance payments to us for heavy maintenance, overhaul or replacement of certain high-value components of the aircraft or engine. These maintenance payments are based on hours or cycles of utilization or on calendar time, depending on the component, and are generally required to be made monthly in arrears. If a lessee is making monthly maintenance payments, we would typically be obligated to reimburse the lessee for costs they incur for heavy maintenance, overhaul or replacement of certain high-value components to the extent of maintenance payments received in respect of the specific maintenance event, usually shortly following the completion of the relevant work.

We record the portion of maintenance payments paid by the lessee that are expected to be reimbursed as maintenance deposit liabilities in the Consolidated Balance Sheets. Reimbursements made to the lessee upon the receipt of evidence of qualifying maintenance work are recorded against the maintenance deposit liability.

In certain acquired leases, we or the lessee may be obligated to make a payment to the other party at lease termination based on redelivery conditions stipulated at the inception of the lease. When the lessee is required to return the aircraft in an improved maintenance condition, we record a maintenance right asset, as a component of other assets, for the estimated value of the end-of-life maintenance payment at acquisition. We recognize payments received as end-of-lease compensation adjustments, within lease income or as a reduction to the maintenance right asset, when payment is received or collectability is assured. In the event we are required to make payments at the end of the lease for redelivery conditions, amounts are accrued as additional maintenance liability and expensed when we are obligated and can reasonably estimate such payments.

Lease Incentives and Amortization—Lease incentives, which include lease acquisition costs related to reconfiguration of the aircraft cabin, other lessee specific modifications and other direct costs, are capitalized and amortized as a reduction of lease income over the primary term of the lease, assuming no lease renewals.

In accounting for acquired leasing equipment, we make estimates about the fair value of the acquired leases. In determining the fair value of these leases, we make assumptions regarding the current fair values of leases for identical or similar equipment in order to determine if the acquired lease is within a fair value range of current lease rates. If a lease is below or above the range of current lease rates, the resulting lease discount or premium is recognized as a lease intangible and amortized into lease income over the remaining term of the lease. Acquired lease intangibles are amortized on a straight-line basis over the remaining lease terms, which collectively had a weighted-average remaining amortization period of approximately 59 months as of December 31, 2022, and are recorded as a component of revenues in the accompanying Consolidated Statements of Operations.

Deferred Financing Costs—Costs incurred in connection with obtaining long term financing are capitalized and amortized to interest expense over the term of the underlying loans. Unamortized deferred financing costs of $29.4 million and $43.0 million as of December 31, 2022 and 2021, respectively, are included in Debt, net in the Consolidated Balance Sheets.

Discontinued Operations—A disposal of an entity or component of an entity is reported in discontinued operations if the disposal represents a strategic shift that has or will have a material impact on our operations and financial results. See Note 3 for additional information related to our discontinued operations.

Operating Leases—We lease equipment pursuant to operating leases. Operating leases with fixed rentals and step rentals are recognized on a straight-line basis over the term of the lease, assuming no renewals. Revenue is not recognized when collection is not reasonably assured. When collectability is not reasonably assured, the customer is placed on non-accrual status and revenue is recognized when cash payments are received.

Generally, under our aircraft lease and engine agreements, the lessee is required to make periodic maintenance payments calculated based on the lessee’s utilization of the leased asset or at the end of the lease. Typically, under our aircraft lease agreements, the lessee is responsible for maintenance, repairs and other operating expenses throughout the term of the lease. These periodic maintenance payments accumulate over the term of the lease to fund major maintenance events, and we are contractually obligated to return maintenance payments to the lessee up to the cost of maintenance events paid by the lessee. In the event the total cost of maintenance events over the term of a lease is less than the cumulative maintenance payments, we are not required to return any unused or excess maintenance payments to the lessee.

recorded as Maintenance revenues. Estimates in recognizing revenue include mean time between removal, projected costs for engine maintenance and forecasted utilization of aircraft which are affected by historical usage patterns and overall industry, market and economic conditions. Significant changes to these estimates could have a material effect on the amount of revenue recognized in the period.

For purchase and lease back transactions, we account for the transaction as a single arrangement. We allocate the consideration paid based on the relative fair value of the aircraft and lease. The fair value of the lease may include a lease premium or discount, which is recorded as a favorable or unfavorable lease intangible.

Finance Leases—From time to time we enter into finance lease arrangements that include a lessee obligation to purchase the leased equipment at the end of the lease term, a bargain purchase option, or provides for minimum lease payments with a present value that equals or exceeds substantially all of the fair value of the leased equipment at the date of lease inception. Net investment in finance leases represents the minimum lease payments due from lessee, net of unearned income. The lease payments are segregated into principal and interest components similar to a loan. Unearned income is recognized on an effective interest method over the lease term and is recorded as finance lease income. The principal component of the lease payment is reflected as a reduction to the net investment in finance leases. Revenue is not recognized when collection is not reasonably assured. When collectability is not reasonably assured, the customer is placed on non-accrual status and revenue is recognized when cash payments are received.

Asset sales revenue—Asset sales revenue primarily consists of the transaction price related to the sale of aircraft and aircraft engines from our Aviation Leasing segment. From time to time, the Company may also assign the related lease agreements to the customer as part of the sale of these assets. We routinely sell leasing equipment to customers and such transactions are considered recurring and ordinary in nature to our business. As such, these sales are accounted for within the scope of ASC 606. Revenue is recognized when a performance obligation is satisfied by transferring control over an asset to a customer. Revenue is recorded with corresponding costs of sales, presented on a gross basis in the Consolidated Statements of Operations. See Note 10 for additional information.

Aerospace Products revenue—Aerospace Products revenue primarily consists of the transaction price related to the sale of repaired CFM56-7B and CFM56-5B engines, engine modules, spare parts and used material inventory, and are accounted for within the scope of ASC 606. Revenue is recognized when a performance obligation is satisfied by transferring control over the related asset to a customer. Revenue is recorded with corresponding costs of sales, presented on a gross basis in the Consolidated Statements of Operations.

Leasing Arrangements—At contract inception, we evaluate whether an arrangement is or contains a lease for which we are the lessee (that is, arrangements which provide us with the right to control a physical asset for a period of time). Operating lease right-of-use (“ROU”) assets and lease liabilities are included in Other assets and Other liabilities in our Consolidated Balance Sheets, respectively. Finance lease ROU assets are recognized in Other assets and lease liabilities are recognized in Other liabilities in our Consolidated Balance Sheets.

All lease liabilities are measured at the present value of the unpaid lease payments, discounted using our incremental borrowing rate based on the information available at commencement date of the lease. ROU assets, for both operating and finance leases, are initially measured based on the lease liability, adjusted for prepaid rent and lease incentives. Operating lease ROU assets are subsequently measured at the carrying amount of the lease liability adjusted for prepaid or accrued lease payments and lease incentives. The finance lease ROU assets are subsequently amortized using the straight-line method.

Operating lease expenses are recognized on a straight-line basis over the lease term. With respect to finance leases, amortization of the ROU asset is presented separately from interest expense related to the finance lease liability and is recorded in Operating expenses in the Consolidated Statements of Operations. Variable lease payments, which are primarily based on usage, are recognized when the associated activity occurs.

We have elected to combine lease and non-lease components for all lease contracts where we are the lessee. Additionally, for arrangements with lease terms of 12 months or less, we do not recognize ROU assets, and lease liabilities and lease payments are recognized on a straight-line basis over the lease term with variable lease payments recognized in the period in which the obligation is incurred.

Concentration of Credit Risk—We are subject to concentrations of credit risk with respect to amounts due from customers. We attempt to limit our credit risk by performing ongoing credit evaluations. No single customer accounted for greater than 10% of total revenue during the year ended December 31, 2022. We earned 11% and 11% of our revenue from one customer in the Aviation Leasing segment during the years ended December 31, 2021, and 2020, respectively.

We maintain cash and restricted cash balances, which generally exceed federally insured limits, and subject us to credit risk, in high credit quality financial institutions. We monitor the financial condition of these institutions and have not experienced any losses associated with these accounts.

Allowance for Doubtful Accounts—We determine the allowance for doubtful accounts based on our assessment of the collectability of our receivables on a customer-by-customer basis. Provision in credit losses is included in Operating expenses in the Consolidated Statement of Operations. The activity in the allowance for doubtful accounts is as follows:

Economic sanctions and export controls against Russia and Russia’s aviation industry were imposed due to its invasion of Ukraine during the first quarter of 2022. As a result of the sanctions imposed on Russian airlines, we terminated all lease agreements with Russian airlines during the first quarter of 2022 and recognized approximately $47.1 million in provision for credit losses during the year ended December 31, 2022. Our allowance for doubtful accounts at December 31, 2022 includes all accounts receivable exposure to Russian and Ukrainian customers.

Comprehensive Income (Loss)—Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances, excluding those resulting from investments by and distributions to owners. Our comprehensive income (loss) represents net income (loss), as presented in the Consolidated Statements of Operations, adjusted for fair value changes for pensions and other postretirement benefits of discontinued operations, and other comprehensive income related to cash flow hedges of our equity method investees of discontinued operations. These changes are also recorded in Accumulated other comprehensive loss in our Consolidated Balance Sheets. The cash flow impact of derivative contracts held by the equity method investees that are not designated as hedging instruments is recognized in Equity in losses (earnings) in unconsolidated entities in our Consolidated Statements of Cash Flows, and the cash flow impact of commodity derivatives held by our consolidated subsidiaries is recognized in Change in fair value of non-hedge derivatives in our Consolidated Statements of Cash Flows.

Other Assets—Other assets is primarily comprised of lease incentives of $37.9 million and $46.9 million, purchase deposits of $6.7 million and $13.7 million, notes receivable of $49.2 million and $22.4 million, operating lease right-of-use assets, net of $3.0 million and $3.8 million, and finance leases, net of $6.4 million and $7.6 million, maintenance right assets of $6.8 million and $5.1 million, prepaid expenses of $1.9 million and $4.0 million as of December 31, 2022 and 2021, respectively. As a result of the sanctions imposed on Russian airlines, we terminated all lease agreements with Russian airlines and recognized approximately $7.5 million in amortization for the remaining lease incentives during the year ended December 31, 2022.

Additionally, the Board of Directors declared cash dividends on the Series A Preferred Shares of $2.06, $2.06 and $2.06 per share for the years ended December 31, 2022, 2021, and 2020, respectively, the Series B Preferred Shares of $2.00,$2.00 and $2.10 per share for the years ended December 31, 2022, 2021 and 2020, respectively, and the Series C Preferred Shares of $2.06 and $1.49 per share for the year ended December 31, 2022 and 2021, respectively.

Recent Accounting Pronouncements—In July 2021, the FASB issued ASU 2021-05, Leases (Topic 842): Lessors—Certain Leases with Variable Lease Payments. This ASU requires lessors to classify and account for a lease with variable lease payments that do not depend on a reference index or a rate as an operating lease if (i) the lease would have been classified as a sales-type lease or a direct financing lease under Topic 842 and (ii) the lessor would have otherwise recognized a day-one loss. This standard is effective for all reporting periods beginning after December 15, 2021. We adopted this guidance in the first quarter of 2022, which did not have a material impact on our consolidated financial statements.
