Notes to Condensed Consolidated Financial Statements
September 30, 2023
(Unaudited)
Unless the context requires otherwise, references to the “Company,” “WLFC,” “we,” “us” or “our” in this Quarterly Report on Form 10-Q refer to Willis Lease Finance Corporation and its subsidiaries.
1.  Summary of Significant Accounting Policies

The significant accounting policies of the Company were described in Note 1 to the Audited Consolidated Financial Statements included in the Company’s Form 10-K for the fiscal year ended December 31, 2022 (the “2022 Form 10-K”). There have been no significant changes in the Company’s significant accounting policies for the nine months ended September 30, 2023.

(a)   Basis of Presentation

The accompanying Unaudited Condensed Consolidated Financial Statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”), consistent in all material respects with those applied in the 2022 Form 10-K, for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission. Therefore, they do not include all information and footnotes normally included in annual consolidated financial statements and should be read in conjunction with the consolidated financial statements and notes thereto included in the 2022 Form 10-K. In the opinion of management, the Unaudited Condensed Consolidated Financial Statements contain all adjustments (consisting principally of normal recurring accruals) necessary for a fair presentation of the Condensed Consolidated Balance Sheets, Statements of Income, Statements of Comprehensive Income, Statements of Redeemable Preferred Stock and Shareholders’ Equity and Statements of Cash Flows for such interim periods presented. Operating results for interim periods are not necessarily indicative of the results that can be expected for a full year. Additionally, certain reclassifications have been made to the prior year presentation to conform to the current year presentation. These reclassifications had no effect on the reported results of operations. An adjustment has been made to the Condensed Consolidated Statements of Income for the three and nine months ended September 30, 2022 as the “Interest revenue” balance has been reported on a separate line item apart from “Other revenue” in the current period financial statements.

In accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements, giving due consideration to materiality. These estimates and judgments are based on historical experience and other assumptions that management believes are reasonable and take into account the economic implications of the recent COVID-19 pandemic and the current high interest rate and inflationary environment on the Company’s critical and significant accounting estimates. However, application of these accounting policies involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, actual results could differ materially from these estimates. The significant estimates made in the accompanying Unaudited Condensed Consolidated Financial Statements include certain assumptions related to intangible assets, long-lived assets, equipment held for sale, allowances for doubtful accounts and credit losses, inventory, deferred in-substance fixed payment use fees included in “Unearned revenue” on the Condensed Consolidated Balance Sheets, and estimated income taxes. Actual results may differ materially from these estimates under different assumptions or conditions. Given the uncertainty in the current high interest rate and inflationary environment, the Company will continue to evaluate the nature and extent of the impact to its business, results of operations and financial condition.

(b) Principles of Consolidation

The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries, including variable interest entities (“VIEs”), where the Company is the primary beneficiary in accordance with consolidation guidance. The Company first evaluates all entities in which it has an economic interest to determine whether for accounting purposes the entity is either a VIE or a voting interest entity. If the entity is a VIE, the Company consolidates the financial statements of that entity if it is the primary beneficiary of such entity’s activities. If the entity is a voting interest entity, the Company consolidates the financial statements of that entity when it has a majority of voting interests in such entity. Intercompany transactions and balances have been eliminated in consolidation.

Table of Contents
The scope and nature of the impact of COVID-19 on the airline industry, and in turn on the Company’s business, continue to evolve and the outcomes are uncertain. Additionally, given the uncertainty in the rapidly changing market and economic conditions related to the current high interest rate and inflationary environment, we will continue to evaluate the nature and extent of the impact on the Company’s business and financial position. The ultimate extent of the effects of the recent COVID-19 pandemic and the current high interest rate and inflationary environment on the Company will depend on future developments, and such effects could exist for an extended period of time.

(d)   Recent Accounting Pronouncements

Recent Accounting Pronouncements Adopted by the Company

At the beginning of January 2023, the Company adopted Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments – Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 revises the measurement of credit losses for financial assets measured at amortized cost from an incurred loss methodology to an expected loss methodology. ASU 2016-13 affects trade receivables, debt securities, net investment in leases, and most other financial assets that represent a right to receive cash. Additional disclosures about significant estimates and credit quality are also required. There was not a significant impact on the Unaudited Condensed Consolidated Financial Statements upon adoption of the standard.

Notes receivable and investments in sales-type leases, net of allowances, represent the current remaining balances we expect to collect for our failed sale-leaseback transactions and sales-type leases. We establish allowances for credit losses to cover probable but specifically unknown losses existing in the portfolio. In doing so, we categorize our financial assets by pools with similar risk characteristics, including whether the financial asset is collateral-backed and whether the customer is placed on non-accrual status. A write-off is recorded when all or part of the financial asset is deemed uncollectible. Write-offs are charged against previously established allowances for credit losses. Partial or full recoveries of amounts previously written off are generally recognized as a reduction in the allowances for credit losses.

Receivables, net of allowances, include amounts billed to customers where the right to payment is unconditional. We maintain an allowance for our trade receivables to provide for the estimated amount that will not be collected, even when the risk of loss is remote. The allowance is measured on a collective pool basis when similar risk characteristics exist and is established as a percentage of accounts receivable. The percentage is based on all available and relevant information including age of outstanding receivables, historical payment experience and loss history, current economic conditions, and, when reasonable and supportable factors exist, management’s expectation of future economic conditions. A write-off is recorded when all or part of the receivable is deemed uncollectible. Write-offs are charged against the previously established allowance for credit losses. Partial or full recoveries of amounts previously written off are generally recognized as a reduction in the allowance for credit losses.

Recent Accounting Pronouncements To Be Adopted by the Company

In August 2023, the FASB issued ASU 2023-05, “Business Combinations – Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement.” The amendments in this ASU apply to the formation of a joint venture, and under this ASU, a joint venture formation is the creation of a new reporting entity that would trigger a new basis of accounting. This ASU requires net assets contributed to the joint venture in a formation transaction to be measured at fair value at the formation date. The amendments in this ASU are effective for all joint ventures within the ASU’s scope that are formed on or after January 1, 2025, with early adoption permitted. Joint ventures formed on or after the effective date of ASU 2023-05 will be required to apply the new guidance prospectively. Joint ventures formed before the ASU’s effective date are permitted to apply the new guidance (1) retrospectively if they have “sufficient information” to do so or (2) prospectively if financial statements have not yet been issued (or made available for issuance). The Company expects to adopt this accounting standard update effective January 1, 2025 and is currently evaluating the potential effects on the consolidated financial statements.

Virtually all of the above debt requires ongoing compliance with certain financial covenants, including debt/equity ratios, minimum tangible net worth and minimum interest coverage ratios, and other eligibility criteria including customer and geographic concentration restrictions. The Company also has certain negative financial covenant obligations that relate to such items as liens, advances, changes in business, sales of assets, dividends and stock repurchases. Compliance with these covenants is tested either monthly, quarterly or annually, as required, and the Company was in full compliance with all financial covenant requirements at September 30, 2023.
6.  Derivative Instruments

The Company periodically holds interest rate derivative instruments to mitigate exposure to changes in interest rates, predominantly one-month term SOFR, with $730.0 million and $727.0 million of variable rate borrowings at September 30, 2023 and December 31, 2022, respectively. As a matter of policy, management does not use derivatives for speculative purposes. As of September 30, 2023, the Company had five interest rate swap agreements. During 2021, the Company entered into four fixed-rate interest swap agreements, each having notional amounts of $100.0 million, two with remaining terms of four months and two with remaining terms of 28 months as of September 30, 2023. One interest rate swap agreement was entered into during 2019 which has a notional outstanding amount of $100.0 million with a remaining term of nine months as of September 30, 2023. The derivative instruments were each designated as cash flow hedges at inception and recorded at fair value.

The Company evaluated the effectiveness of the swap agreements to hedge the interest rate risk associated with its variable rate debt and concluded at the swap inception dates that each swap was highly effective in hedging that risk. The Company evaluates the effectiveness of the hedging relationships on an ongoing basis and concluded there was no ineffectiveness in the hedges for the period ended September 30, 2023.

The Company estimates the fair value of derivative instruments using a discounted cash flow technique. Valuation of the derivative instruments requires certain assumptions for underlying variables and the use of different assumptions would result in a different valuation. Management believes it has applied assumptions consistently during the period. The Company applies hedge accounting and accounts for the change in fair value of its cash flow hedges through other comprehensive income for all derivative instruments.

The net fair value of the interest rate swaps as of September 30, 2023 was $25.1 million, representing an asset and is reflected within “Other assets” on the Condensed Consolidated Balance Sheets. The net fair value of the interest rate swaps as of December 31, 2022 was $34.8 million, representing an asset and reflected within “Other assets” on the Condensed Consolidated Balance Sheets. The Company recorded an adjustment to interest expense of $(6.3) million and $(2.7) million during the three months ended September 30, 2023 and 2022, respectively, and $(17.4) million and $(3.3) million during the nine months ended September 30, 2023 and 2022, respectively, from derivative instruments.

Effect of Derivative Instruments on Earnings in the Condensed Consolidated Statements of Income and Comprehensive Income 

The following table provides additional information about the financial statement effects related to the cash flow hedges for the three and nine months ended September 30, 2023 and 2022:

Total$(3,627)$8,049 $(9,647)$29,145 

The effective portion of the change in fair value on a derivative instrument designated as a cash flow hedge is reported as a component of other comprehensive income and is reclassified into earnings in the period during which the transaction being hedged affects earnings when it is determined to be improbable that the forecasted transaction will occur. The ineffective portion of the hedges, if any, is recorded in earnings in the current period.

Counterparty Credit Risk

The Company evaluates the creditworthiness of the counterparties under its hedging agreements. The counterparties for the interest rate swaps are large financial institutions that possess investment grade credit ratings. Based on these ratings, the Company believes that the counterparties are credit-worthy and that their continuing performance under the hedging agreements is probable and do not require the counterparties to provide collateral or other security to the Company.
7.  Income Taxes

Income tax expense for the three and nine months ended September 30, 2023 was $5.7 million and $13.3 million, respectively. The effective tax rate for the three and nine months ended September 30, 2023 was 28.1% and 28.9%, respectively. Income tax expense for the three and nine months ended September 30, 2022 was $2.0 million and $0.5 million, respectively. The effective tax rate for the three and nine months ended September 30, 2022 was 23.6% and (5.9)%, respectively. The Company’s effective tax rates differed from the U.S. federal statutory rate of 21.0% primarily due to executive compensation exceeding $1.0 million as defined in Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), and a discrete item recorded in the quarter ended March 31, 2022 associated with a write-down of engines due to the Russia and Ukraine conflict. Refer to Note 8 “Fair Value Measurements” for further detail on the write-downs related to Russia.

The Company records tax expense or benefit for unusual or infrequent items discretely in the period in which they occur. The Company’s tax rate is subject to change based on changes in the mix of assets leased to domestic and foreign lessees, the proportion of revenue generated within and outside of California, the amount of executive compensation exceeding $1.0 million as defined in Section 162(m) of the Code, and numerous other factors, including changes in tax law.

8. Fair Value Measurements

The fair value of a financial instrument represents the amount at which the instrument could be exchanged in a current transaction between willing parties in contrast to a forced sale or liquidation. Fair value estimates are made at a specific point in time, based on relevant market information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of judgment, and therefore cannot be determined with precision.

Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Accounting standards establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value and also establishes the following three levels of inputs that may be used to measure fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

18

Table of Contents
Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The following methods and assumptions were used by the Company in estimating fair value disclosures for financial instruments:

Cash and cash equivalents, restricted cash, receivables, and accounts payable: The amounts reported in the accompanying Condensed Consolidated Balance Sheets approximate fair value due to their short-term nature.

Notes receivable: The carrying amount of the Company’s outstanding balance on its Notes receivable as of September 30, 2023 and December 31, 2022 was estimated to have a fair value of approximately $88.6 million and $83.5 million, respectively, based on the fair value of estimated future payments calculated using interest rates that approximate prevailing market rates at each period end (Level 2 inputs).

Investments in sales-type leases: The carrying amount of the Company’s outstanding balance on its Investments in sales-type leases as of September 30, 2023 and December 31, 2022 was estimated to have a fair value of approximately $5.3 million and $6.4 million, respectively, based on the fair value of estimated future payments calculated using interest rates that approximate prevailing market rates at each period end (Level 2 inputs).

Debt obligations: The carrying amount of the Company’s outstanding balance on its Debt obligations as of September 30, 2023 and December 31, 2022 was estimated to have a fair value of approximately $1,482.6 million and $1,540.2 million, respectively, based on the fair value of estimated future payments calculated using interest rates that approximate prevailing market rates at each period end (Level 2 inputs).

Assets Measured and Recorded at Fair Value on a Recurring Basis and a Nonrecurring Basis

As of September 30, 2023 and December 31, 2022, the Company measured the fair value of its interest rate swap agreements based on Level 2 inputs, due to the usage of inputs that can be corroborated by observable market data. The Company estimates the fair value of derivative instruments using a discounted cash flow technique. The net fair value of the interest rate swaps as of September 30, 2023 was $25.1 million, representing an asset. The net fair value of the interest rate swaps as of December 31, 2022 was $34.8 million, representing an asset. The Company recorded an adjustment to interest expense of $(6.3) million and $(2.7) million during the three months ended September 30, 2023 and 2022, respectively, and $(17.4) million and $(3.3) million during the nine months ended September 30, 2023 and 2022, respectively, from derivative instruments.

Goodwill is assessed for impairment annually, at each year end by comparing the fair values of the reporting units to their carrying amounts. The Company first assesses qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test.

The Company determines fair value of long-lived assets held and used, such as Equipment held for operating lease and Equipment held for sale, by reference to independent appraisals, quoted market prices (e.g. an offer to purchase) and other factors. An impairment charge is recorded when the carrying value of the asset exceeds its fair value. The Company uses Level 2 inputs to measure write-downs of equipment held for lease and equipment held for sale.

Write-downs of equipment to their estimated fair values totaled $0.7 million for the three months ended September 30, 2023, reflecting the adjustment of the carrying values of one engine and two airframes. Write-downs of equipment to their estimated fair values totaled $2.4 million for the nine months ended September 30, 2023, reflecting the adjustment of the carrying values of three engines and two airframes. As of September 30, 2023, included within equipment held for lease and equipment held for sale was $28.9 million in remaining book values of 15 assets which were previously written down.

Write-downs of equipment to their estimated fair values totaled $0.7 million for the three months ended September 30, 2022, reflecting the adjustment of the carrying value of one impaired engine. Write-downs of equipment to their estimated fair values totaled $21.8 million for the nine months ended September 30, 2022, reflecting the adjustment of the carrying values of four impaired engines. Of this write-down, $20.4 million reflects the impairment of two engines located in Russia which were determined, due to the Russia and Ukraine conflict, to be unrecoverable. The remaining write-downs were in the ordinary course of business.
9.  Earnings Per Share

Basic earnings per common share is computed by dividing net income, less preferred stock dividends and accretion of preferred stock issuance costs, by the weighted average number of common shares outstanding for the period. Treasury stock is excluded from the weighted average number of shares of common stock outstanding. Diluted earnings per share attributable to common stockholders is computed based on the weighted average number of shares of common stock and dilutive securities outstanding during the period. Dilutive securities are common stock equivalents that are freely exercisable into common stock at less than market prices or otherwise dilute earnings if converted. The net effect of common stock equivalents is based on the incremental common stock that would be issued upon the vesting of restricted stock using the treasury stock method. Common stock equivalents are not included in diluted earnings per share when their inclusion is antidilutive. Additionally, redeemable preferred stock is not convertible and does not affect dilutive shares.

There were no anti-dilutive shares for the three and nine months ended September 30, 2023. There were no anti-dilutive shares excluded from the computation of diluted weighted average earnings per share for the three months ended September 30, 2022. There were 0.2 million anti-dilutive shares excluded from the computation of diluted weighted average loss per share for the nine months ended September 30, 2022.

Redemption: The Preferred Stock has no stated maturity date, however the holders of the Preferred Stock have the option to require the Company to redeem all or any portion of the Preferred Stock for cash upon occurrence of any significant changes in operating results, ownership structure, or liquidity events as defined in the Preferred Stock purchase agreements. The redemption price is $20.00 per share plus dividends accrued but not paid. The Company is accreting the Preferred Stock to redemption value over the period from the date of issuance to the date first callable by the Preferred Stockholders (September 2024 for both of the Series A Preferred Stock and Series A-2 Preferred Stock, as a result of the First Amendment to Second Amended and Restated Certificate of Designations, Preferences, and Relative Rights and Limitations of Series A Cumulative Redeemable Preferred Stock dated as of September 26, 2023), such that the carrying amounts of the securities will equal the redemption amounts at the earliest redemption dates.
11.  Stock-Based Compensation Plans

The components of stock-based compensation expense were as follows:
Three months ended September 30,Nine months ended September 30,
2023202220232022
(in thousands)(in thousands)
2023 Incentive Stock Plan$3,843 $3,098 $10,557 $10,732 
Employee Stock Purchase Plan28 48 113 84 
Total Stock Compensation Expense$3,871 $3,146 $10,670 $10,816 

The 2023 Incentive Stock Plan (the “2023 Plan”) amended and restated the prior 2021 Incentive Stock Plan. The 2023 Plan authorized 1,750,000 shares for issuance, plus the number of shares remaining for issuance under the prior stock plan and any future forfeited awards under the prior plan. Stock-based compensation is in the form of restricted stock awards (“RSAs”). The RSAs are subject to either service-based vesting, which is typically between one and four years, in which a specific period of continued employment must pass before an award vests, or performance-based vesting, which is typically between one and two years. The expense associated with these awards is recognized on a straight-line basis over the respective vesting period, with forfeitures accounted for as they occur. For any vesting tranche of an award, the cumulative amount of compensation cost recognized is equal to the portion of the grant‑date fair value of the award tranche that is actually vested at that date.

As of September 30, 2023, the Company had granted 1,591,800 RSAs under the 2023 Plan and had 2,052,796 shares available for future issuance. The fair value of the restricted stock awards equaled the stock price at the grant date.

The following table summarizes the restricted stock activity during the nine months ended September 30, 2023:

Under the Employee Stock Purchase Plan (“ESPP”), as amended and restated effective November 2021, 425,000 shares of common stock have been reserved for issuance. Eligible employees may designate no more than 10% of their base cash compensation to be deducted each pay period for the purchase of common stock under the ESPP. Participants may purchase the lesser of 1,000 shares or $25,000 of common stock in any one calendar year. Each January 31 and July 31, shares of common stock are purchased with the employees’ payroll deductions from the immediately preceding six months at a price per share of 85% of the lesser of the market price of the common stock on the purchase date or the market price of the common stock on the date of entry into an offering period. During the nine months ended September 30, 2023 and 2022, 9,832 and 19,789 shares of common stock, respectively, were issued under the ESPP. The Company issues new shares through its transfer agent upon an employee stock purchase.
12. Reportable Segments

The Company has two reportable segments: (i) Leasing and Related Operations, which involves acquiring and leasing, primarily pursuant to operating leases, commercial aircraft, aircraft engines, and other aircraft equipment, and the selective purchase and resale of commercial aircraft engines and other aircraft equipment, and other related businesses and (ii) Spare Parts Sales, which involves the purchase and resale of after-market engine parts, whole engines, engine modules, and portable aircraft components.

The Company evaluates the performance of each of the segments based on profit or loss after general and administrative expenses. While the Company believes there are synergies between the two business segments, the segments are managed separately because each requires different business strategies.

The following tables present a summary of the reportable segments (in thousands):

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the Unaudited Condensed Consolidated Financial Statements and notes thereto included under Part I, Item 1 of this Quarterly Report on Form 10-Q. In addition, reference should be made to our Audited Consolidated Financial Statements and notes thereto and related “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Form 10-K for the fiscal year ended December 31, 2022 (the “2022 Form 10-K”). In addition to historical consolidated financial information, the following discussion contains forward-looking statements that reflect our plans, estimates and beliefs, including potential impacts of the recent COVID-19 pandemic and the current high interest rate and inflationary environment on our business, results of operations and financial condition. Our actual results may differ materially from those contained in or implied by any forward-looking statements. The financial information included in this discussion and in our consolidated financial statements may not be indicative of our consolidated financial position, operating results, changes in equity and cash flows in the future. See “Special Note Regarding Forward-Looking Statements” included earlier in this report.
Overview

Our core business is acquiring and leasing commercial aircraft and aircraft engines and related aircraft equipment pursuant to operating leases, all of which we sometimes collectively refer to as “equipment.” As of September 30, 2023, the majority of our leases were operating leases, with the exception of certain failed sale-leaseback transactions classified as notes receivable under the guidance provided by Accounting Standards Codification (“ASC”) 842 and investments in sales-type leases. As of September 30, 2023, we had 73 lessees in 40 countries. Our portfolio is continually changing due to equipment acquisitions and sales. As of September 30, 2023, we had $2,171.0 million of equipment held in our operating lease portfolio, $94.0 million of notes receivable, $13.4 million of maintenance rights, and $5.5 million of investments in sales-type leases, which represented 351 engines, 12 aircraft, one marine vessel, and other leased parts and equipment. As of September 30, 2023, we also managed 194 engines, aircraft and related equipment on behalf of other parties.

Our wholly-owned and vertically-integrated subsidiary Willis Asset Management Limited (“Willis Asset Management”) is focused on the engine management and consulting business. Willis Aeronautical Services, Inc. (“Willis Aero”) is a wholly-owned and vertically-integrated subsidiary whose primary focus is the sale of aircraft engine parts and materials through the acquisition or consignment of aircraft and engines.

We actively manage our portfolio and structure our leases to maximize the residual values of our leased assets. Our leasing business focuses on popular Stage IV commercial jet engines manufactured by CFMI, General Electric, Pratt & Whitney, Rolls Royce and International Aero Engines. These engines are the most widely used engines in the world, powering Airbus, Boeing, Bombardier and Embraer aircraft.

Risks and Uncertainties

The scope and nature of the impact of COVID-19 on the airline industry, and in turn the Company’s business, continue to evolve and the outcomes are uncertain. Additionally, given the uncertainty in the rapidly changing market and economic conditions related to the current high interest rate and inflationary environment, we will continue to evaluate the nature and extent of the impact to the Company’s business and financial position. The ultimate extent of the effects of the recent COVID-19 pandemic and the current high interest rate and inflationary environment on the Company will depend on future developments, and such effects could exist for an extended period of time.
Critical Accounting Policies and Estimates

There have been no material changes to our critical accounting policies and estimates from the information provided in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our 2022 Form 10-K.

Total revenue$105,745 $76,891 37.5 %

Lease Rent Revenue. Lease rent revenue consists of rental income from long-term and short-term engine leases, aircraft leases, and other leased parts and equipment. Lease rent revenue increased by $14.1 million, or 35.6%, to $53.6 million in the three months ended September 30, 2023 from $39.5 million for the three months ended September 30, 2022. The increase is due to an increase in the number of engines acquired and placed on lease, including an increase in utilization compared to that of the prior period. During the three months ended September 30, 2023, we purchased equipment (including capitalized costs) totaling $31.0 million, which consisted of five engines and other parts and equipment purchased for our lease portfolio. During the three months ended September 30, 2022, we purchased equipment (including capitalized costs) totaling $139.4 million, which consisted of 37 engines and other parts and equipment purchased for our lease portfolio.

One customer accounted for more than 10% of total lease rent revenue during each of the three months ended September 30, 2023 and 2022, respectively.

At September 30, 2023, the Company had $2,171.0 million of equipment held in our operating lease portfolio, $94.0 million of notes receivable, $13.4 million of maintenance rights, and $5.5 million of investments in sales-type leases. At September 30, 2022, the Company had $2,078.8 million of equipment held in our operating lease portfolio, $82.5 million of notes receivable, $21.4 million of maintenance rights, and $6.7 million of investments in sales-type leases. Average utilization (based on net book value) was approximately 85% and 80% for the three months ended September 30, 2023 and 2022, respectively.

Maintenance Reserve Revenue. Maintenance reserve revenue increased $17.3 million, or 84.4%, to $37.7 million for the three months ended September 30, 2023 from $20.4 million for the three months ended September 30, 2022. Long-term maintenance revenue is influenced by end of lease compensation and the realization of long-term maintenance reserves associated with engines coming off lease. There was $3.3 million long-term maintenance revenue recognized for the three months ended September 30, 2023, compared to $4.5 million in the comparable prior period. “Non-reimbursable” maintenance reserve revenue is directly influenced by on lease engine flight hours and cycles. Engines out on lease with “non-reimbursable” usage fees generated $34.4 million of short-term maintenance revenues, compared to $16.0 million in the comparable prior period. As of September 30, 2023, there was $24.7 million of deferred in-substance fixed payment use fees included in “Unearned revenue.” These deferred in-substance fixed payment use fees represent portfolio utilization beyond the maintenance reserve revenues reflected in our Condensed Consolidated Statements of Income.

Spare Parts and Equipment Sales. Spare parts and equipment sales decreased by $3.6 million, or 51.8%, to $3.4 million for the three months ended September 30, 2023 compared to $7.0 million for the three months ended September 30, 2022. The decrease in spare parts sales for the three months ended September 30, 2023 reflects variations in the timing of sales. There were no equipment sales for the three months ended September 30, 2023. Equipment sales for the three months ended September 30, 2022 were $0.4 million for the sale of one engine.

Interest Revenue. Interest revenue increased by $0.3 million, to $2.1 million for the three months ended September 30, 2023 from $1.8 million in 2022. The increase is primarily the result of an increase in notes receivable of $11.5 million, partially offset by a decrease in investments in sales-type leases of $1.2 million.

Table of Contents
Gain on Sale of Leased Equipment. During the three months ended September 30, 2023, we sold one engine and one airframe from the lease portfolio for a net gain of $0.8 million. During the three months ended September 30, 2022, we sold two engines from the lease portfolio for a net gain of $0.9 million.
Other Revenue. Other revenue increased by $1.0 million, or 13.8%, to $8.2 million for the three months ended September 30, 2023 from $7.2 million for the three months ended September 30, 2022. Other revenue consists primarily of management fee income, lease administration fees, third party consignment commissions earned, service fee revenue, and other discrete revenue items. The increase in the third quarter of 2023 compared to the prior year period primarily reflects increased managed service revenue.
Depreciation and Amortization Expense. Depreciation and amortization expense increased by $1.0 million, or 4.7%, to $23.1 million for the three months ended September 30, 2023 compared to $22.1 million for the three months ended September 30, 2022. The increase reflects the growth in the portfolio as compared to the prior year period.
Cost of Spare Parts and Equipment Sales. Cost of spare parts and equipment sales decreased by $2.2 million, or 51.9%, to $2.0 million for the three months ended September 30, 2023 compared to $4.2 million for the three months ended September 30, 2022, reflecting the decline in spare part sales. There was no equipment or cost of equipment sales for the three months ended September 30, 2023. Cost of equipment sales were $43 thousand for the three months ended September 30, 2022.
Write-down of Equipment. Write-down of equipment was $0.7 million for the three months ended September 30, 2023, reflecting the write-down of one engine and two airframes. Write-down of equipment was $0.7 million for the three months ended September 30, 2022, reflecting the write-down of one engine.
General and Administrative Expenses. General and administrative expenses increased by $11.2 million, or 49.2%, to $34.0 million for the three months ended September 30, 2023 compared to $22.8 million for the three months ended September 30, 2022. The increase primarily reflects a $7.1 million increase in personnel costs. Additionally, a $1.4 million increase in outside service fees and a $1.1 million increase in aviation hull war insurance as a result of the Russia and Ukraine conflict further contributed to the increased general and administrative expenses.

Technical Expense. Technical expense consists of the non-capitalized cost of engine repairs, engine thrust rental fees, outsourced technical support services, sublease engine rental expense, engine storage and freight costs. Technical expense increased by $4.7 million to $6.9 million for the three months ended September 30, 2023 compared to $2.1 million for the three months ended September 30, 2022, primarily due to a higher level of engine repair activity.

Net Finance Costs. Net finance costs increased $2.7 million, or 16.9%, to $19.1 million for the three months ended September 30, 2023 compared to $16.3 million for the three months ended September 30, 2022, primarily due to an increase in short-term interest rates, which drive borrowing costs in our revolving credit facility.

Income Tax Expense. Income tax expense was $5.7 million for the three months ended September 30, 2023 compared to income tax expense of $2.0 million for the three months ended September 30, 2022. The effective tax rate for the third quarter of 2023 was 28.1% compared to 23.6% in the prior year period. The Company’s effective tax rate differed from the U.S. federal statutory rate of 21.0% primarily due to executive compensation exceeding $1.0 million as defined in Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”).

Lease Rent Revenue. Lease rent revenue increased by $46.9 million, or 41.0%, to $161.2 million for the nine months ended September 30, 2023, compared to $114.3 million for the nine months ended September 30, 2022. The increase is due to an increase in the number of engines acquired and placed on lease, including an increase in utilization compared to the prior year period. During the nine months ended September 30, 2023, we purchased equipment (including capitalized costs) totaling $142.5 million, which consisted of 19 engines and other parts and equipment purchased for our lease portfolio. During the nine months ended September 30, 2022, we purchased equipment (including capitalized costs) totaling $220.7 million, which primarily consisted of 37 engines and other parts and equipment purchased for our lease portfolio.
Two customers and one customer accounted for more than 10% of total lease rent revenue during the nine months ended September 30, 2023 and 2022, respectively.
At September 30, 2023, the Company had $2,171.0 million of equipment held in our operating lease portfolio, $94.0 million of notes receivable, $13.4 million of maintenance rights, and $5.5 million of investments in sales-type leases. At September 30, 2022, the Company had $2,078.8 million of equipment held in our operating lease portfolio, $82.5 million of notes receivable, $21.4 million of maintenance rights, and $6.7 million of investments in sales-type leases. Average utilization (based on net book value) was approximately 85% and 82% for the nine months ended September 30, 2023 and 2022, respectively.
 
Maintenance Reserve Revenue. Maintenance reserve revenue increased $37.1 million, or 62.3%, to $96.6 million for the nine months ended September 30, 2023 from $59.5 million for the nine months ended September 30, 2022. Long-term maintenance revenue was $10.1 million for the nine months ended September 30, 2023 compared to $27.8 million in the prior year period. Engines out on lease with “non-reimbursable” usage fees generated $86.5 million of short-term maintenance revenues compared to $31.8 million in the comparable prior period. As of September 30, 2023, there was $24.7 million of deferred in-substance fixed payment use fees included in “Unearned revenue.” These deferred in-substance fixed payment use fees represent portfolio utilization beyond the maintenance reserve revenues reflected in our Condensed Consolidated Statements of Income.
 
Spare Parts and Equipment Sales. Spare parts and equipment sales decreased by $7.4 million, or 36.4%, to $13.0 million for the nine months ended September 30, 2023 compared to $20.4 million in the prior year period. The decrease in spare parts sales for the nine months ended September 30, 2023 reflects variations in the timing of sales. There were no equipment sales during the nine months ended September 30, 2023. Equipment sales for the nine months ended September 30, 2022 were $0.4 million for the sale of one engine.
 
Gain on Sale of Leased Equipment. During the nine months ended September 30, 2023, we sold five engines, one airframe, and other parts and equipment from the lease portfolio for a net gain of $5.1 million. During the nine months ended September 30, 2022, we sold 15 engines and other parts and equipment from the lease portfolio for a net gain of $3.7 million.
Gain on Sale of Financial Assets. There was no gain on sale of financial assets during the nine months ended September 30, 2023 as we did not sell any notes receivable. During the nine months ended September 30, 2022, we sold four notes receivable for a net gain of $3.1 million.

Other Revenue. Other revenue increased by $5.1 million, or 30.0%, to $22.0 million for the nine months ended September 30, 2023 from $16.9 million for the nine months ended September 30, 2022. Other revenue consists primarily of management fee income, lease administration fees, third party consignment commissions earned, service fee revenue, and other discrete revenue items. The increase for the nine months ended September 30, 2023 compared to the prior year period primarily reflects increased managed service revenue.

Depreciation and Amortization Expense. Depreciation and amortization expense increased by $2.7 million, or 4.0%, to $68.1 million for the nine months ended September 30, 2023 compared to $65.5 million for the nine months ended September 30, 2022. The increase reflects the growth in the portfolio as compared to the prior year period.
 
Cost of Spare Parts and Equipment Sales. Cost of spare parts and equipment sales decreased by $6.5 million, or 40.4%, to $9.6 million for the nine months ended September 30, 2023 compared to $16.1 million for the nine months ended September 30, 2022, reflecting the decline in pare part sales. There was no equipment or cost of equipment sales for the nine months ended September 30, 2023. Cost of equipment sales were $43 thousand for the nine months ended September 30, 2022.
 
Write-down of Equipment. Write-down of equipment was $2.4 million for the nine months ended September 30, 2023, primarily reflecting the write-down of three engines and two airframes. Write-down of equipment was $21.8 million for the nine months ended September 30, 2022, primarily reflecting the write-down of four engines. Of this write-down, $20.4 million reflects the impairment of two engines located in Russia which were determined due to the Russia and Ukraine conflict to be unrecoverable. The remaining write-downs were in the ordinary course of business.
 
General and Administrative Expenses. General and administrative expenses increased by $38.8 million, or 58.0%, to $105.6 million for the nine months ended September 30, 2023 compared to $66.8 million for the nine months ended September 30, 2022. The increase primarily reflects a $21.0 million increase in personnel costs. Additionally, a $2.6 million increase in outside service fees, a $3.5 million increase in aviation hull war insurance as a result of the Russia and Ukraine conflict, and a $3.2 million increase in other taxes due to an increase in business conducted in India further contributed to the increased general and administrative expenses.
 
Technical Expense. Technical expense increased by $3.4 million, or 30.3%, to $14.6 million for the nine months ended September 30, 2023 compared to $11.2 million for the nine months ended September 30, 2022, primarily due to a higher level of engine repair activity and thrust rental fees.
 
Net Finance Costs. Net finance costs increased by $7.3 million, or 14.9%, to $56.5 million for the nine months ended September 30, 2023 compared to $49.2 million for the nine months ended September 30, 2022, primarily due to an increase in short-term interest rates, which drive borrowing costs in our revolving credit facility.

Income Tax Expense. Income tax expense was $13.3 million for the nine months ended September 30, 2023 compared to $0.5 million for the nine months ended September 30, 2022. The effective tax rate for the nine months ended September 30, 2023 was 28.9% compared to (5.9)% in the prior year period. The Company’s effective tax rate differed from the U.S. federal statutory rate of 21.0% primarily due to executive compensation exceeding $1.0 million as defined in Section 162(m) of the Code and a discrete item recorded in 2022 associated with a write-down of engines due to the Russia and Ukraine conflict.
Financial Position, Liquidity and Capital Resources
Liquidity
At September 30, 2023, the Company had $5.4 million of cash and cash equivalents, and $50.3 million of restricted cash. We fund our operations primarily from cash provided by our leasing activities. We finance our growth through borrowings secured primarily by our equipment lease portfolio. Cash of approximately $159.8 million and $219.0 million for the nine months ended September 30, 2023 and 2022, respectively, was derived from our borrowing activities. In these same time periods, $221.9 million and $160.9 million, respectively, was used to pay down related debt.

The impact of the recent COVID-19 pandemic on the global business environment has caused and could result in additional customer bankruptcies, early lease returns, payment defaults, and rental concessions which could reduce rent or result in deferred customer payments, negatively impacting our financial results. Additionally, given the uncertainty in the rapidly changing market and economic conditions related to the current high interest rate and inflationary environment, we will continue to evaluate the nature and extent of the impact to the Company’s business and financial position.

For any interest rate swaps that we enter into, we will be exposed to risk in the event of non-performance of the interest rate hedge counter-parties. We may hedge additional amounts of our floating rate debt in the future.

Cash Flows Discussion
Cash flows provided by operating activities were $169.0 million and $82.6 million for the nine months ended September 30, 2023 and 2022, respectively.

Cash flows from operations are driven significantly by payments made under our lease agreements, which comprise lease revenue, security deposits and maintenance reserves, and are offset by interest expense and general and administrative costs. Cash received as maintenance reserve payments for some of our engines on lease are partially restricted by our debt arrangements. The lease revenue stream, in the short-term, is at fixed rates while a portion of our debt is at variable rates. If interest rates increase, it is unlikely we could increase lease rates in the short term and this would cause a reduction in our earnings and operating cash flows. Revenue and maintenance reserves are also affected by the amount of equipment off lease. Approximately 84% and 80%, by book value, of our assets were on-lease as of September 30, 2023 and December 31, 2022, respectively. The average utilization rate (based on net book value) for the nine months ended September 30, 2023 and 2022 was approximately 85% and 82%, respectively. If there is an increase in off-lease rates or deterioration in lease rates that are not offset by reductions in interest rates, there will be a negative impact on earnings and cash flows from operations.

Cash flows used in investing activities were $132.1 million for the nine months ended September 30, 2023 and primarily reflected $15.4 million related to leases which were classified as notes receivable under ASC 842 and $142.5 million for the purchase of equipment held for operating lease (including capitalized costs and prepaid deposits made in the period), partly offset by proceeds from sale of equipment (net of selling expenses) of $25.0 million. Cash flows used in investing activities were $144.1 million for the nine months ended September 30, 2022 and primarily reflected $15.3 million related to leases which were classified as notes receivable under ASC 842 and $220.7 million for the purchase of equipment held for operating lease (including capitalized costs and prepaid deposits made in the period), partly offset by proceeds from the sale of equipment and notes receivable (net of selling expenses) of $53.4 million and $40.7 million, respectively.
Cash flows used in financing activities were $70.2 million for the nine months ended September 30, 2023 and primarily reflected $221.9 million in principal payments, partially offset by $159.8 million in proceeds from debt obligations. Cash flows provided by financing activities were $47.2 million for the nine months ended September 30, 2022 and primarily reflected $219.0 million in proceeds from debt obligations, partially offset by $160.9 million in principal payments and $5.2 million of share repurchases.
Preferred Stock Dividends
The Company’s Series A-1 Preferred Stock accrue quarterly dividends at the rate per annum of 6.5% per share through October 15, 2023 and at the rate per annum of 8.5% per share thereafter. The Series A-2 Preferred Stock accrue quarterly dividends at the rate per annum of 6.5% per share. During each of the nine months ended September 30, 2023 and 2022, the Company paid total dividends of $2.4 million, on the Series A-1 and Series A-2 Preferred Stock.
Debt Obligations and Covenant Compliance
At September 30, 2023, debt obligations consisted of loans totaling $1,788.0 million, net of unamortized issuance costs, payable with interest rates varying between approximately 3.1% and 7.4%. Substantially all of our assets are pledged to secure our obligations to creditors. For further information on our debt instruments, see Note 5 “Debt Obligations” in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Virtually all of our debt requires our ongoing compliance with certain financial covenants including debt/equity ratios, minimum tangible net worth and minimum interest coverage ratios, and other eligibility criteria including customer and geographic concentration restrictions. Under our revolving credit facility, we can borrow no more than 85% of an engine’s net book value and 65% of an airframe’s, spare parts inventory’s or other assets net book value. Therefore, we must have other available funds for the balance of the purchase price of any new equipment to be purchased. Our revolving credit facility, certain indentures and other debt related agreements also contain cross-default provisions. If we do not comply with the covenants or eligibility requirements, we may not be permitted to borrow additional funds and accelerated payments may become necessary. Additionally, much of the debt is secured by engines and aircraft, and to the extent that engines or aircraft are sold, repayment of that portion of the debt could be required.

Table of Contents
At September 30, 2023, we were in compliance with the covenants specified in our revolving credit facility, including the Interest Coverage Ratio requirement of at least 2.25 to 1.00, and the Total Leverage Ratio requirement to remain below 4.00 to 1.00. The Interest Coverage Ratio, as defined in the credit facility, is the ratio of earnings before interest, taxes, depreciation and amortization (EBITDA) and other one-time charges to consolidated interest expense. The Total Leverage Ratio, as defined in the credit facility, is the ratio of total indebtedness to tangible net worth. At September 30, 2023, we were in compliance with the covenants specified in the WEST III, WEST IV, WEST V and WEST VI indentures and servicing and other debt related agreements.

Off-Balance Sheet Arrangements

As of September 30, 2023, we had no material off-balance sheet arrangements or obligations that have or are reasonably likely to have a current or future effect on our financial condition, change in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures, or capital resources that are material to investors.

Contractual Obligations and Commitments

Repayments of our gross debt obligations primarily consist of scheduled installments due under term loans and are funded by the use of unrestricted cash reserves and from cash flows from ongoing operations. The table below summarizes our contractual commitments at September 30, 2023:

Total$2,414,751 $919,563 $384,558 $835,892 $274,738 

From time to time we enter into contractual commitments to purchase engines directly from original equipment manufacturers. As of the date of this report we are committed to purchasing 18 additional new LEAP-1A engines for $282.8 million, and nine additional new LEAP-1B engines for $155.8 million. Our purchase agreements generally contain terms that allow the Company to defer or cancel purchase commitments in certain situations. These deferrals or conversions would not result in penalties or increased costs other than any potential increase due to the normal year-over-year change in engine list prices, which is akin to ordinary inflation. The Company continues to expect demand for LEAP-1B engines to increase as the 737 Max continues to be re-certified and aircraft (and their installed engines) that have been parked and in storage for more than one year begin the technical process of returning to service.

In December 2020, we entered into definitive agreements for the purchase of 25 modern technology aircraft engines. As part of the purchase, we have committed to certain future overhaul and maintenance services which are anticipated to range between $77.7 million and $112.0 million by 2030.

We have estimated the interest payments due under debt obligations by applying the interest rates applicable at September 30, 2023 to the remaining debt, adjusted for the estimated debt repayments identified in the table above. Actual interest payments made will vary due to changes in the rates.

We believe our equity base, internally generated funds and existing debt facilities are sufficient to maintain our level of operations for the next twelve months. A decline in the level of internally generated funds could result if the amount of equipment off-lease increases, there is a decrease in availability under our existing debt facilities, or there is a significant step-up in borrowing costs. Such decline would impair our ability to sustain our level of operations. We continue to discuss additions to our capital base with our commercial and investment banks. If we are not able to access additional capital, our ability to continue to grow our asset base consistent with historical trends will be impaired and our future growth limited to that which can be funded from internally generated capital.

Item 3. Quantitative and Qualitative Disclosures about Market Risk
Our primary market risk exposure is that of interest rate risk. A change in rates would affect our cost of borrowing. Increases in interest rates, which may cause us to raise the implicit rates charged to our customers, could result in a reduction in demand for our leases. Alternatively, we may price our leases based on market rates so as to keep the fleet on-lease and suffer a decrease in our operating margin due to interest costs that we are unable to pass on to our customers. As of September 30, 2023, $730.0 million of our outstanding debt is variable rate debt. We estimate that for every one percent increase or decrease in interest rates on our variable rate debt, net of our interest rate swaps, our annual interest expense would increase or decrease by $2.3 million.
We hedge a portion of our borrowings from time to time, effectively fixing the rate of these borrowings. This hedging activity helps protect us against reduced margins on longer term fixed rate leases. Such hedging activities may limit our ability to participate in the benefits of any decrease in interest rates but may also protect us from increases in interest rates. Furthermore, since lease rates tend to vary with interest rate levels, it is possible that we can adjust lease rates for the effect of changes in interest rates at the termination of leases. Other financial assets and liabilities are at fixed rates.
We are also exposed to currency devaluation risk. Substantially all of our leases require payment in U.S. dollars. During the nine months ended September 30, 2023 and 2022, 66% and 58%, respectively, of our lease rent revenues came from non-United States domiciled lessees. If these lessees’ currency devalues against the U.S. dollar, the lessees could potentially encounter difficulty in making their lease payments.
Item 4. Controls and Procedures

(a) Evaluation of disclosure controls and procedures. In accordance with Rule 13a-15(b) promulgated under the Securities Exchange Act of 1934, as amended (“Exchange Act”) we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness and design of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange Act), as of the end of the period covered by this report. Based on such evaluation, our CEO and CFO have concluded that as of September 30, 2023, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

(b) Inherent Limitations on Controls. Management, including the CEO and CFO, does not expect that our disclosure controls and procedures will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs.

(c) Changes in internal control over financial reporting. There has been no change in our internal control over financial reporting during our fiscal quarter ended September 30, 2023 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.
PART II — OTHER INFORMATION
Item 1A. Risk Factors
Investors should carefully consider the risks in the “Risk Factors” in Part 1: Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 10, 2023, and our other filings with the SEC. These risks are not the only ones facing the Company. Additional risks not currently known to us or that we currently believe are immaterial may also impair our business operations. Any of these risks could adversely affect our business, cash flows, financial condition and results of operations. The trading price of our common stock could fluctuate due to any of these risks, and investors may lose all or part of their investment. In assessing these risks, investors should also refer to the other information contained or incorporated by reference in this Quarterly Report on Form 10-Q. There have been no material changes in our risk factors from those discussed in our Annual Report on Form 10-K for the year ended December 31, 2022.
