SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q contains certain forward-looking statements, including, without limitation, statements concerning the conditions in our industry, our operations, our economic performance and financial condition, including, in particular, statements relating to our business, operations, growth strategy and service development efforts and potential impact of the COVID-19 pandemic on the Company's business, operating results and financial condition. The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for certain forward-looking statements so long as such information is identified as forward-looking and is accompanied by meaningful cautionary statements identifying important factors that could cause actual results to differ materially from those projected in the information. When used in this Quarterly Report on Form 10-Q, the words “may,” “might,” “should,” “estimate,” “project,” “plan,” “anticipate,” “expect,” “intend,” “outlook,” “believe” and other similar expressions are intended to identify forward-looking statements and information. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of their dates. These forward-looking statements are based on estimates and assumptions by our management that, although we believe to be reasonable, are inherently uncertain and subject to a number of risks and uncertainties. These risks and uncertainties include, without limitation, those in our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the Securities and Exchange Commission (“SEC”) on March 15, 2021, this quarterly report on Form 10-Q for the three and six months ended June 30, 2021, and our other reports filed with the SEC. We undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law. Reference is also made to such risks and uncertainties detailed from time to time in our other filings with the SEC.

WILLIS LEASE FINANCE CORPORATION
AND SUBSIDIARIES
Notes to Condensed Consolidated Financial Statements
June 30, 2021
(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, 2020 (the “2020 Form 10-K”). There have been no significant changes in the Company’s significant accounting policies for the six months ended June 30, 2021.
(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 2020 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 2020 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. Additionally, operating results for interim periods are not necessarily indicative of the results that can be expected for a full year.
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 the inputs into management's estimates and judgment consider the economic implications of the COVID-19 pandemic 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, allowance for doubtful accounts, inventory and estimated income taxes. Actual results may differ materially from these estimates under different assumptions or conditions. Given the uncertainty in the rapidly changing market and economic conditions related to the COVID-19 pandemic, 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 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 entity when it has a majority of voting interests in such entity. Intercompany transactions and balances have been eliminated in consolidation.
(c) Risks and Uncertainties
As a result of the COVID-19 pandemic, the Company has temporarily closed its headquarters and other offices, required its employees and contractors to predominately work remotely, and implemented travel restrictions, all of which represent a significant disruption in how the Company operates its business. The Company has also taken various proactive actions in an attempt to mitigate the financial impact of the COVID-19 pandemic. During 2020, 9% of our employees were either furloughed, or subject to a form of reduced compensation which was subsequently reversed in 2021. The operations of the Company’s partners and customers have
10

Table of Contents
likewise been disrupted. The worldwide spread of the COVID-19 virus has resulted in a global slowdown of economic activity. While the duration and extent of the COVID-19 pandemic depends on future developments that cannot be accurately predicted at this time, such as the extent and effectiveness of containment actions, it has had an adverse effect on the global economy and the ultimate societal and economic impact of the COVID-19 pandemic remains unknown. In particular, the ongoing COVID-19 pandemic has caused significant disruptions to the airline industry and has resulted in a dramatic reduction in demand for air travel domestically and abroad, which is likely to continue for the foreseeable future. Lower demand for air travel in turn presents significant risks to the Company, resulting in impacts which have adversely affected the Company’s business, results of operation, and financial condition. Lower demand for spare parts and engine and airframe leasing has negatively impacted collections of accounts receivable, caused the Company’s lessee customers to not enter into new leases, resulted in reduced spending by new and existing customers for leases or spare parts or equipment, resulted in lower usage fees, caused some of the Company’s customers to go out of business, and limited the ability of the Company’s personnel to travel to customers and potential customers. The Company is not able to evaluate or foresee the full extent of these impacts at the current time. During the three and six months ended June 30, 2021, the Company experienced declining average utilization and a corresponding decrease in revenue as compared to the prior year comparable period. Additionally, as of June 30, 2021, the Company has, in certain situations, agreed to rent concessions which resulted in a total reduction to rent revenues of $0.1 million during the three months ended June 30, 2021 and $0.2 million during the six months ended June 30, 2021. Rent concessions for the three and six months ended June 30, 2020 resulted in a total reduction of rent revenue of $3.1 million, respectively. The rent concessions provide lessees with payment deferral options or reduced rent, where the revised cash flows are substantially the same or less (i.e., the rights of the lessor and obligations of the lessee have not substantially increased) as the original lease agreements. There is no impact on the timing of revenue recognition for rent concessions that result in short term payment deferrals. The rent concessions with reduced rent qualify for the COVID-19 practical expedient to account for the rent concessions outside of the modification framework. Due to the impact of recent events, including challenges from declines in market conditions, the Company performed quarterly interim impairment analyses. The results of the analyses indicated $0.3 million additional impairments in the three and six months ended June 30, 2021.
Other than what has been reflected in the Unaudited Condensed Consolidated Financial Statements, the Company is not aware of any specific event or circumstance related to the COVID-19 pandemic that would require it to update its estimates or judgments or adjust the carrying value of its assets or liabilities. Actual results could differ from those estimates and any such differences may be material to the Unaudited Condensed Consolidated Financial Statements.
(d) Recent Accounting Pronouncements
Recent Accounting Pronouncements Adopted by the Company
In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. ASU 2019-12 also improves consistent application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The Company adopted this guidance effective January 1, 2021 and it did not materially impact our consolidated financial statements and related disclosures.
In March 2021, the FASB issued ASU No. 2021-01, “Reference Rate Reform (Topic 848), Scope”, which clarifies certain optional expedients to all derivatives affected by the discounting transition, regardless of whether the derivatives reference the London Interbank Offered Rate (“LIBOR”) or another rate expected to be discounted or whether the modification replaces or has the potential to replace the reference rate expected to be discounted. The amendments in this guidance are effective upon issuance through December 31, 2022. The Company adopted this guidance upon issuance. When the transition occurs, the Company expects to apply this expedient to its existing debt instruments and interest rate swaps that reference LIBOR, and to any other new transactions that reference LIBOR or another reference rate that is discontinued, through December 31, 2022. The adoption of this ASU did not impact the Company’s consolidated financial statements.
Recent Accounting Pronouncements To Be Adopted by the Company
In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). 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. In November 2018, the FASB issued ASU 2018-19, “Codification Improvements to Topic 326, Financial Instruments – Credit Losses.” This ASU clarifies receivables from operating leases are accounted for using the lease guidance and not as financial instruments. In April 2019, the FASB issued ASU 2019-04, “Codification Improvements to Topic 326, Financial Instruments – Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial
11

Table of Contents
Instruments.” This ASU clarifies various scoping and other issues arising from ASU 2016-13. In March 2020, the FASB issued ASU 2020-03, “Codification Improvements to Financial Instruments.” This ASU improves the Codification and amends the interaction of Topic 842 and Topic 326. The amendments in ASU 2016-13 are effective for the Company on January 1, 2023, with early adoption permitted. The Company expects to adopt this accounting standard update effective January 1, 2023. The Company is evaluating the potential effects on the consolidated financial statements.

In June 2021, WLFC entered into Amendment No. 2 to the Fourth Amended and Restated Credit Agreement dated as of June 7, 2019, which updates the provisions relating to the future discontinuance of the LIBOR and sets forth the mechanics for establishing the Secured Overnight Financing Rate (“SOFR”) as a benchmark replacement rate.
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 covenants such as liens, advances, change in business, sales of assets, dividends and stock repurchases. These covenants are tested either monthly, quarterly or annually and the Company was in full compliance with all financial covenant requirements at June 30, 2021.
6. Derivative Instruments
The Company periodically holds interest rate derivative instruments to mitigate exposure to changes in interest rates, predominantly one-month LIBOR, with $688.0 million and $783.1 million of variable rate borrowings at June 30, 2021 and December 31, 2020, respectively. As a matter of policy, management does not use derivatives for speculative purposes. As of June 30, 2021, the Company had five interest rate swap agreements. During the first quarter of 2021, the Company entered into four additional fixed-rate interest swap agreements, each having notional amounts of $100.0 million, two with remaining terms of 31 months and two with remaining terms of 55 months as of June 30, 2021. 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 36 months as of June 30, 2021. One interest rate swap agreement which the Company entered into in 2016 expired in April 2021. 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 June 30, 2021.
The Company estimates the fair value of derivative instruments using a discounted cash flow technique and has used creditworthiness inputs that corroborate observable market data when evaluating the Company’s and counterparty’s risk of non-performance. 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 June 30, 2021 was $1.8 million, representing an asset of $3.9 million and a liability of $2.1 million. The net fair value of the interest rate swaps as of December 31, 2020 was $4.0 million, representing a liability. The Company recorded interest expense of $0.5 million and $0.6 million during the three months ended June 30, 2021 and 2020, respectively, and $1.4 million and $0.6 million during the six months ended June 30, 2021 and 2020, respectively, from derivative instruments.

Effect of Derivative Instruments on Earnings in the Statements of Income and on Comprehensive Income
The following tables provide additional information about the financial statement effects related to the cash flow hedges for the three and six months ended June 30, 2021 and 2020:

Derivatives in Cash Flow Hedging Relationships |  | Amount of (Loss) Gain Recognized in OCI on Derivatives (Effective Portion)
| Three Months Ended June 30, |  | Six Months Ended June 30,
| 2021 |  | 2020 |  | 2021 |  | 2020
|  | (in thousands) |  | (in thousands)
Interest rate contracts |  | $ | (769) |  |  | $ | (454) |  |  | $ | 5,727 |  |  | $ | (3,772) |
Total |  | $ | (769) |  |  | $ | (454) |  |  | $ | 5,727 |  |  | $ | (3,772) |

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 or it is probable that the forecasted transaction will not 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 possessed investment grade credit ratings. Based on these ratings, the Company believes that the counterparties were credit-worthy and that their continuing performance under the hedging agreements was probable and did not require the counterparties to provide collateral or other security to the Company.
7. Income Taxes
Income tax benefit for the three and six months ended June 30, 2021 was $1.9 million and $2.3 million, respectively. The effective tax rate for the three and six months ended June 30, 2021 was 103.1% and 64.1%, respectively. Income tax expense for the three and six months ended June 30, 2020 was $4.4 million and $8.6 million, respectively. The effective tax rate for the three and six months ended June 30, 2020 was 44.8% and 47.1%, respectively. The increase in the effective tax rate was predominantly due to executive compensation exceeding $1.0 million as defined in IRS code Section 162(m).
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, state taxes, the amount of executive compensation exceeding $1.0 million as defined in IRS code Section 162(m) and numerous other factors, including changes in tax law.
The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted on March 27, 2020 in the U.S., and includes several provisions related to employment and income taxes, including provisions for the deferral of the employer portion of social security taxes through December 31, 2020. On December 27, 2020, the U.S. government enacted the Consolidated Appropriations Act, 2021, which enhances and expands certain provisions of the CARES Act. The Company qualified for the Employment Retention Credit (“ERC”) and recognized a credit of $0.7 million and $1.4 million for the three and six months ended June 30, 2021, respectively, as a reduction to social security tax.
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:
17

Table of Contents
Level 1 - Quoted prices in active markets for identical assets or liabilities.
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 June 30, 2021 and December 31, 2020 was estimated to have a fair value of approximately $198.0 million and $159.2 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).
•Debt obligations: The carrying amount of the Company’s outstanding balance on its Debt obligations as of June 30, 2021 and December 31, 2020 was estimated to have a fair value of approximately $1,926.8 million and $1,691.0 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
As of June 30, 2021 and December 31, 2020, 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 and has used creditworthiness inputs that corroborate observable market data evaluating the Company’s and counterparties’ risk of non-performance. The net fair value of the interest rate swaps as of June 30, 2021 was $1.8 million, representing a net asset of $3.9 million and a net liability of $2.1 million. The net fair value of the interest rate swaps as of December 31, 2020 was $4.0 million, representing a net liability. The Company recorded interest expense of $0.5 million and $0.6 million during the three months ended June 30, 2021 and 2020, respectively, and $1.4 million and $0.6 million during the six months ended June 30, 2021 and 2020, respectively, from derivative instruments.
Assets Measured and Recorded at Fair Value on a Nonrecurring Basis
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.

| Total Losses
| Three Months Ended June 30, |  | Six Months Ended June 30,
| 2021 |  | 2020 |  | 2021 |  | 2020
| (in thousands) |  | (in thousands)
Equipment held for lease | $ | 2,246 |  |  | $ | 6,997 |  |  | $ | 4,113 |  |  | $ | 9,056 |
Equipment held for sale | — |  |  | — |  |  | — |  |  | 70 |
Total | $ | 2,246 |  |  | $ | 6,997 |  |  | $ | 4,113 |  |  | $ | 9,126 |

Write-downs of equipment to their estimated fair values totaled $2.2 million for the three months ended June 30, 2021, reflecting an adjustment of the carrying value of four impaired engines. Write-downs of equipment to their estimated fair values totaled $4.1 million for the six months ended June 30, 2021 reflecting an adjustment of the carrying value of four impaired engines and one airframe. As of June 30, 2021, included within equipment held for lease and equipment held for sale was $40.7 million in remaining book values of 23 assets which were previously written down.

A write-down of $7.0 million was recorded during the three months ended June 30, 2020 due to a management decision to monetize three engines either by sale to a third party or for part-out and two engines as a result of our impairment analysis. A write-down of $9.1 million was recorded during the six months ended June 30, 2020 due to a management decision to monetize five engines either by sale to a third party or for part-out and two engines as a result of our impairment analysis.
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 six months ended June 30, 2021. There were 0.2 million anti-dilutive shares excluded from the computation of diluted weighted average earnings per common share for the three months ended June 30, 2020. There were no anti-dilutive shares for the six months ended June 30, 2020.
The following table presents the calculation of basic and diluted EPS (in thousands, except per share data):

| Three Months Ended June 30, |  | Six Months Ended June 30,
| 2021 |  | 2020 |  | 2021 |  | 2020
Net (loss) income attributable to common shareholders | $ | (774) |  |  | $ | 4,540 |  |  | $ | (2,928) |  |  | $ | 7,995 |

10. Equity
Common Stock Repurchase
Effective December 31, 2018, the Board of Directors approved the renewal of the existing common stock repurchase plan extending the plan through December 31, 2020 and amending the plan to allow for repurchases of up to $60.0 million of the Company's common stock until such date. Effective December 31, 2020, the Board of Directors approved the renewal of the existing common stock repurchase plan extending the plan through December 31, 2022. Repurchased shares are immediately retired. No shares were repurchased during the six months ended June 30, 2021. During the six months ended June 30, 2020, the Company repurchased a total of 54,626 shares of common stock for approximately $1.5 million at a weighted average price of $27.79 per share.
Redeemable Preferred Stock
Dividends: The Company’s Series A-1 Preferred Stock and Series A-2 Preferred Stock accrue quarterly dividends at the rate per annum of 6.5% per share.

| 2021 |  | 2020 |  | 2021 |  | 2020
| (in thousands) |  | (in thousands)
2007 Stock Incentive Plan | $ | 957 |  |  | $ | 703 |  |  | $ | 1,642 |  |  | $ | 1,728 |
2018 Stock Incentive Plan | 3,507 |  |  | 2,237 |  |  | 5,506 |  |  | 3,297 |
Employee Stock Purchase Plan | 72 |  |  | 75 |  |  | 150 |  |  | 107 |
Total Stock Compensation Expense | $ | 4,536 |  |  | $ | 3,015 |  |  | $ | 7,298 |  |  | $ | 5,132 |

The significant stock compensation plans are described below.
The 2007 Stock Incentive Plan (the “2007 Plan”) was adopted in May 2007. Under the 2007 Plan, a total of 2,800,000 shares were authorized for stock-based compensation available in the form of either restricted stock awards (“RSAs”) or stock options. The RSAs are subject to service-based vesting, typically between one and four years, where a specific period of continued employment must pass before an award vests. 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 June 30, 2021, there were no stock options outstanding under the 2007 Plan.
The 2018 Stock Incentive Plan (the “2018 Plan”) was adopted in May 2018. Under the 2018 Plan, a total of 800,000 shares are authorized for stock-based compensation, plus the number of shares remaining under the 2007 Plan and any future forfeited awards under the 2007 Plan, in the form of RSAs. The RSAs are subject to service and performance-based vesting, typically between one and four years, where a specific period of continued employment or service must pass before an award vests. 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 June 30, 2021, the Company had granted 885,300 RSAs under the 2018 Plan and had 9,296 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 restricted stock activity under the 2007 and 2018 Plans during the six months ended June 30, 2021:

| Shares
Balance as of December 31, 2020 | 581,715 |
Shares granted | 286,550 |
Shares forfeited | — |
Shares vested | (339,657) |
Balance as of June 30, 2021 | 528,608 |

Under the Employee Stock Purchase Plan (“ESPP”), as amended and restated effective April 1, 2018, 325,000 shares of common stock have been reserved for issuance. Eligible employees may designate not more than 10% of their cash compensation to be deducted each pay period for the purchase of common stock under the ESPP. Participants may purchase not more than 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. In the six months ended June 30, 2021 and 2020, 8,307 and 3,892 shares of common stock, respectively, were issued under the ESPP. The Company issues new shares through its transfer agent upon 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):

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 June 30, 2021, all 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. As of June 30, 2021, we had 68 lessees in 40 countries. Our portfolio is continually changing due to equipment acquisitions and sales. As of June 30, 2021, $1,889.9 million of equipment held in our operating lease portfolio and $195.6 million of notes receivable represented 300 engines, eight aircraft, one marine vessel and other leased parts and equipment. As of June 30, 2021, we also managed 487 engines, aircraft and related equipment on behalf of other parties.
Our wholly owned 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 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.
As previously disclosed, on March 16, 2021, we received a non-binding indication of interest (the “Indication of Interest”) to acquire all of the outstanding shares of the Company’s common stock not already owned by Charles F. Willis IV, the Company’s Chief Executive Officer and largest stockholder (individually and together with an entity controlled by him), and Austin C. Willis, the Company’s Senior Vice President, Corporate Development (together, the “Group”), in exchange for cash consideration of $42.00 per share. The Indication of Interest was filed as an exhibit to a Schedule 13D/A filed by the Group on March 17, 2021. The Indication of Interest did not provide details on how the Group proposed to finance its proposed acquisition. On June 25, 2021, the Company’s Chief Executive Officer delivered a letter (the “Letter”) to the Special Committee of the Board of Directors reaffirming interest in acquiring all of the Company’s common stock not already owned by the Group in exchange for cash consideration of $42.00 per share (the “Offer Price”) and clarifying that he does not intend to increase the Offer Price.
On March 19, 2021, the Board of Directors of the Company formed a committee (the “Independent Committee”) comprised solely of independent directors to review, evaluate and negotiate any proposal from the Group. The Independent Committee is currently in negotiations with the Group regarding its Indication of Interest that could result in our becoming a privately-held company. See “Risk Factors” in Part II, Item 1A of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2021, and our other filings with the SEC.
COVID-19 Impact
Throughout the remainder of the year, we plan to continue to stay focused on cost control and remain prudent with our capital expenditures. We have temporarily closed our headquarters and other offices, required our employees and contractors to predominately work remotely, and implemented travel restrictions, all of which represent a significant disruption in how we operate our business. We have taken various proactive actions in an attempt to mitigate the financial impact of the COVID-19 pandemic. Additionally, during 2020, 9% of our employees were either furloughed, or subject to a form of reduced compensation which was subsequently reversed in 2021. The operations of our partners and customers have likewise been disrupted. The worldwide spread of the COVID-19 virus has resulted in a global slowdown of economic activity. While the duration and extent of the COVID-19 pandemic depends on future developments that cannot be accurately predicted at this time, such as the extent and effectiveness of

containment actions, it has had an adverse effect on the global economy and the ultimate societal and economic impact of the COVID-19 pandemic remains unknown. In particular, the ongoing COVID-19 pandemic has caused significant disruptions to the airline industry that has resulted in a dramatic reduction in demand for air travel domestically and abroad, which is likely to continue for the foreseeable future. Lower demand for air travel in turn presents significant risks to our Company, resulting in impacts that have adversely affected our business, results of operations, and financial condition. Lower demand for spare parts and engine and airframe leasing has negatively impacted collections of accounts receivable, caused our lessee customers to not enter into new leases, resulted in reduced spending by new and existing customers for leases or spare parts or equipment, resulted in lower usage fees, caused some of our customers to go out of business, and limited the ability of our personnel to travel to customers and potential customers. During the three and six months ended June 30, 2021, we experienced declining average utilization and a corresponding decrease in revenue as compared to the prior year comparable period. Additionally, as of June 30, 2021, the Company has, in certain situations, agreed to rent concessions which resulted in a total reduction to rent revenues of $0.1 million during the second quarter of 2021 and $0.2 million year-to-date. Rent concessions for the three and six months ended June 30, 2020 resulted in a total reduction of rent revenue of $3.1 million, respectively. The rent concessions provide lessees with payment deferral options or reduced rent, where the revised cash flows are substantially the same or less (i.e., the rights of the lessor and obligations of the lessee have not substantially increased) as the original lease agreements. There is no impact on the timing of revenue recognition for rent concessions that result in short term payment deferrals. The rent concessions with reduced rent qualify for the COVID-19 practical expedient to account for the rent concessions outside of the modification framework. Due to the impact of recent events, including challenges from declines in market conditions, we performed quarterly interim impairment analyses. The results of the analyses indicated $0.3 million additional impairments in the three and six months ended June 30, 2021.
The scope and nature of the impact of COVID-19 on the airline industry, and in turn our business, continue to evolve and the outcomes are uncertain. Given the uncertainty in the rapidly changing market and economic conditions related to COVID-19, we will continue to evaluate the nature and extent of the impact to our business and financial position. The ultimate extent of the effects of the COVID-19 pandemic on our Company will depend on future developments, and such effects could exist for an extended period of time.

Results of Operations
Three months ended June 30, 2021 compared to the three months ended June 30, 2020
Revenue is summarized as follows:

| Three Months Ended June 30,
| 2021 |  | 2020 |  | % Change
| (dollars in thousands)
Lease rent revenue | $ | 32,431 |  |  | $ | 38,454 |  |  | (15.7) | %
Maintenance reserve revenue | 17,278 |  |  | 29,986 |  |  | (42.4) | %
Spare parts and equipment sales | 3,569 |  |  | 2,855 |  |  | 25.0 | %
Loss on sale of leased equipment | — |  |  | (700) |  |  | (100.0) | %
Asset transition fee | 6,256 |  |  | — |  |  | 100.0 | %
Other revenue | 6,938 |  |  | 4,388 |  |  | 58.1 | %
Total revenue | $ | 66,472 |  |  | $ | 74,983 |  |  | (11.4) | %

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 decreased by $6.0 million, or 15.7%, to $32.4 million in the three months ended June 30, 2021 from $38.5 million for the three months ended June 30, 2020. The decrease is primarily due to lower average utilization directly related to continued impacts of the COVID-19 pandemic, when compared to the prior year period. During the three months ended June 30, 2021, we purchased equipment (including capitalized costs) totaling $37.3 million, which consisted of five engines and one aircraft purchased for our lease portfolio. During the three months ended June 30, 2020, we purchased equipment (including capitalized costs) totaling $1.3 million, which consisted of other parts and equipment purchased for our lease portfolio.
One customer accounted for more than 10% of total lease rent revenue during the three months ended June 30, 2021 and 2020, respectively.

Table of Contents
The aggregate net book value of equipment held for lease at June 30, 2021 and 2020 consisted of $1,889.9 million and $195.6 million notes receivable and $1,653.7 million and $170.4 million notes receivable, respectively. Average utilization (based on net book value) was approximately 81% and 86% for the three months ended June 30, 2021 and 2020, respectively.
Maintenance Reserve Revenue. Maintenance reserve revenue decreased $12.7 million, or 42.4%, to $17.3 million for the three months ended June 30, 2021 from $30.0 million for the three months ended June 30, 2020. 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. Long-term maintenance revenue was $14.8 million for the three months ended June 30, 2021 compared to $27.2 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 $2.5 million of short-term maintenance revenues compared to $2.8 million in the comparable prior period, resulting from the decline in global flight traffic related to the COVID-19 pandemic.
Spare Parts and Equipment Sales. Spare parts sales increased by $0.7 million, or 25.0%, to $3.6 million for the three months ended June 30, 2021 compared to $2.9 million for the three months ended June 30, 2020. The increase in spare parts sales for the second quarter of 2021 was driven by an increase in industry wide demand compared to the prior year period which was impacted by the COVID-19 pandemic. There were no equipment sales for the three months ended June 30, 2021 or 2020.
Loss on Sale of Leased Equipment. There were no sales of leased equipment during the three months ended June 30, 2021. D uring the three months ended June 30, 2020, we sold three engines and two airframes from the lease portfolio for a net loss of $0.7 million.
Asset Transition Fee. Asset transition fee of $6.3 million during the three months ended June 30, 2021 reflects a settlement received from the close out of an engine transition program. There was no asset transition fee in the three months ended June 30, 2020.
Other Revenue. Other revenue increased by $2.6 million, to $6.9 million in the three months ended June 30, 2021 from $4.4 million in the three months ended June 30, 2020. The increase primarily reflects increases of $1.6 million in service related fees and $0.9 million in interest income from our notes receivable.
Depreciation and Amortization Expense. Depreciation and amortization expense decreased by $0.4 million, or 1.8%, to $23.3 million for the three months ended June 30, 2021 compared to $23.8 million for the three months ended June 30, 2020. The slight decrease reflects the change in mix of portfolio as compared to the prior year period.
Cost of Spare Parts and Equipment Sales. Cost of spare parts sales increased by $0.6 million, or 23.8%, to $3.3 million for the three months ended June 30, 2021 compared to $2.6 million for the three months ended June 30, 2020. There was no equipment or cost of equipment sales for the three months ended June 30, 2021 and 2020.
Write-down of Equipment. Write-down of equipment was $2.2 million for the three months ended June 30, 2021, reflecting the write-down of four engines. Write-down of equipment was $7.0 million for the three months ended June 30, 2020, reflecting the write-down of five engines, two of which resulted from the Company’s interim impairment analysis which indicated the carrying values of two engines were in excess of their respective fair value by $0.5 million.
General and Administrative Expenses. General and administrative expenses increased by $4.3 million, or 28.0%, to $19.5 million for the three months ended June 30, 2021 compared to $15.2 million for the three months ended June 30, 2020. The increase primarily reflects increased stock-based compensation as compared to the prior year period which was primarily driven by an increase in stock price compared to the prior year period.
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 $0.8 million, or 56.4%, to $2.3 million for the three months ended June 30, 2021 compared to $1.5 million for the three months ended June 30, 2020. The increase is primarily due to an increase in engine repairs, partly offset by a decrease in technical support services driven by lower industry-wide demand due to the continued impact of the COVID-19 pandemic.
Net Finance Costs. Net finance costs increased $0.9 million, or 5.6%, to $17.0 million for the three months ended June 30, 2021 compared to $16.1 million for the three months ended June 30, 2020. The increase is due to higher interest expense as compared to the prior year period. Net finance costs are also influenced by the execution of the WEST VI transaction, which temporarily increases total leverage and interest expense at the Company. Debt obligations outstanding, net of unamortized debt issuance costs, as of June 30, 2021 and 2020, were $1,911.2 million and $1,520.2 million, respectively. After adjustment for interest rate derivative instruments, $188.0 million and $353.0 million as of June 30, 2021 and 2020, respectively, were tied to one-month LIBOR. As of June 30, 2021 and 2020, we held $500 million and $200 million of interest rate derivative instruments on this debt and one-month LIBOR was 0.10% and 0.16% respectively.

Income Tax (Benefit) Expense. Income tax (benefit) expense was $(1.9) million for the three months ended June 30, 2021 compared to $4.4 million for the three months ended June 30, 2020. The effective tax rate for the second quarter of 2021 was 103.1% compared to 44.8% in the prior year period. The increase in the effective tax rate was predominantly due to executive compensation exceeding $1.0 million as defined in IRS code Section 162(m).
Six months ended June 30, 2021 compared to the six months ended June 30, 2020
Revenue is summarized as follows:

| Six Months Ended June 30,

Total revenue | $ | 127,597 |  |  | $ | 156,592 |  |  | (18.5) | %

Lease Rent Revenue. Lease rent revenue decreased by $20.9 million, or 24.6%, to $64.0 million for the six months ended June 30, 2021, compared to $84.8 million for the six months ended June 30, 2020. The decrease is primarily due to lower utilization directly related to the COVID-19 pandemic, when compared to the prior year period. During the six months ended June 30, 2021, we purchased equipment (including capitalized costs) totaling $63.8 million, which primarily consisted of seven engines, one aircraft and other parts and equipment purchased for our lease portfolio. During the six months ended June 30, 2020, we purchased equipment (including capitalized costs) totaling $77.0 million, which primarily consisted of four engines and other parts and equipment purchased for our lease portfolio.
One customer accounted for more than 10% of total lease rent revenue during the six months ended June 30, 2021 and 2020, respectively.
The aggregate net book value of equipment held for lease at June 30, 2021 and 2020, was $1,889.9 million and $195.6 million notes receivable and $1,653.7 million and $170.4 million notes receivable, respectively. Average utilization (based on net book value) was approximately 80% and 86% for the six months ended June 30, 2021 and 2020, respectively.
Maintenance Reserve Revenue. Maintenance reserve revenue decreased $13.4 million, or 26.6%, to $37.1 million for the six months ended June 30, 2021 from $50.5 million for the six months ended June 30, 2020. Long-term maintenance revenue was $31.9 million for the six months ended June 30, 2021 compared to $35.8 million in the comparable prior period. Engines out on lease with “non-reimbursable” usage fees generated $5.2 million of short-term maintenance revenues compared to $14.7 million in the comparable prior period, resulting from the decline in global flight traffic related to the COVID-19 pandemic.
Spare Parts and Equipment Sales. Spare parts and equipment sales decreased by $3.8 million, or 32.0%, to $8.1 million for the six months ended June 30, 2021 compared to $12.0 million in the prior year period. Spare parts sales for the six months ended June 30, 2021 were $8.1 million, compared to $11.1 million in the comparable period in 2020. The decline in spare parts sales paralleled the slowdown in global flight traffic, which was directly affected by impacts of the COVID-19 pandemic. There were no equipment sales during the six months ended June 30, 2021, compared to $0.9 million for the sale of one engine in the comparable period of 2020.
Gain on Sale of Leased Equipment. There were no sales of leased equipment during the six months ended June 30, 2021. During the six months ended June 30, 2020 we sold 10 engines and two airframes from the lease portfolio for a net gain of $1.4 million.
Asset Transition Fee. Asset transition fee was $6.3 million in the six months ended June 30, 2021 reflecting the settlement received from the close out of an engine transition program. There was no asset transition fee in the six months ended June 30, 2020.
Other Revenue. Other revenue increased by $4.3 million, or 53.9%, to $12.2 million for the six months ended June 30, 2021 from $7.9 million for the six months ended June 30, 2020. The increase primarily reflects increases of $1.4 million in service related fees and $2.8 million in interest income from our notes receivable.

Table of Contents
Depreciation and Amortization Expense. Depreciation and amortization expense increased by $0.3 million, to $47.5 million for the six months ended June 30, 2021 compared to $47.2 million for the six months ended June 30, 2020. The increase reflects the larger net book value of the lease portfolio and the change in mix of portfolio to new generation engines, 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 24.1%, to $7.1 million for the six months ended June 30, 2021 compared to $9.3 million for the six months ended June 30, 2020. Cost of spare parts for the six months ended June 30, 2021 were $7.1 million compared to $9.2 million in the prior year period due to lower spare parts sales. The reduced sales were driven by lower industry wide demand resulting from the impacts of the COVID-19 pandemic. There was no cost of equipment sales for the six months ended June 30, 2021, compared to $0.1 million in the prior year period.
Write-down of Equipment. Write-down of equipment was $4.1 million for the six months ended June 30, 2021, primarily reflecting the write-down of four engines and one airframe. Write-down of equipment was $9.1 million for the six months ended June 30, 2020 reflecting the write-down of seven engines, two of which resulted from the Company’s interim impairment analysis which indicated the carrying values of two engines were in excess of their respective fair value by $0.5 million.
General and Administrative Expenses. General and administrative expenses increased by $0.9 million, or 2.5%, to $35.7 million for the six months ended June 30, 2021 compared to $34.8 million for the six months ended June 30, 2020. The increase primarily reflects increased stock-based compensation as compared to the prior year period which was primarily driven by an increase in stock price.
Technical Expense. Technical expense increased by $1.0 million, or 39.0%, to $3.6 million for the six months ended June 30, 2021 compared to $2.6 million for the six months ended June 30, 2020. The increase primarily reflects the increase in engine repairs.
Net Finance Costs. Net finance costs decreased by $4.5 million, or 12.2%, to $32.0 million for the six months ended June 30, 2021 compared to $36.5 million for the six months ended June 30, 2020. The decrease was primarily due to a loss on debt extinguishment of $4.7 million recognized in the prior year period.
Income Tax (Benefit) Expense. Income tax (benefit) expense was $(2.3) million for the six months ended June 30, 2021 compared to $8.6 million for the six months ended June 30, 2020. The effective tax rate for the six months ended June 30, 2021 was 64.1% compared to 47.1% in the prior year period. The increase in the effective tax rate was predominantly due to Section 162(m) limitation.
Financial Position, Liquidity and Capital Resources
Liquidity
At June 30, 2021, the Company had $229.2 million of cash, cash equivalents and restricted cash, of which $16.5 million was unrestricted. We fund our operations primarily from cash provided by our leasing activities. We finance our growth through borrowings secured by our equipment lease portfolio. Cash of approximately $395.7 million and $690.2 million for the six months ended June 30, 2021 and 2020, respectively, was derived from our borrowing activities. In these same time periods, $175.8 million and $419.5 million, respectively, was used to pay down related debt.
The impact of the 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.
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 anticipate that we may hedge additional amounts of our floating rate debt in the future.
Cash Flows Discussion
Cash flows provided by operating activities was $42.8 million and $43.0 million for the six months ended June 30, 2021 and 2020, 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
28

Table of Contents
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 78%, by book value, of our assets were on-lease as of June 30, 2021 and December 31, 2020, respectively. The average utilization rate (based on net book value) for the six months ended June 30, 2021 and 2020 was approximately 80% and 86%, 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 was $101.5 million for the six months ended June 30, 2021 and primarily reflected $42.5 million related to leases entered into during the first half of 2021 which were classified as notes receivable under ASC 842 and $63.8 million for the purchase of equipment held for operating lease (including capitalized costs and prepaid deposits made in the period). Cash flows used in investing activities was $193.7 million in the six months ended June 30, 2020, and primarily reflected $136.0 million related to eight leases entered into during the first half of 2020 which were classified as notes receivable under ASC 842 and $77.0 million for the purchase of equipment held for operating lease (including capitalized costs and prepaid deposits made in the period), partly offset by $17.7 million in proceeds from sales of equipment (net of selling expenses).
Cash flows provided by financing activities was $208.9 million for the six months ended June 30, 2021 and primarily reflected $395.7 million in proceeds from debt obligations, partially offset by $175.8 million in principal payments. Cash flows provided by financing activities was $258.5 million for the six months ended June 30, 2020 and primarily reflected $690.2 million in proceeds from debt obligations, partially offset by $419.5 million in principal payments and $8.2 million in debt issuance and prepayment costs.
Preferred Stock Dividends
The Company’s Series A-1 Preferred Stock and Series A-2 Preferred Stock accrue quarterly dividends at the rate per annum of 6.5% per share. During the six months ended June 30, 2021 and 2020, the Company paid total dividends of $1.6 million, respectively, on the Series A-1 and Series A-2 Preferred Stock.
Debt Obligations and Covenant Compliance
In June 2021, WLFC entered into Amendment No. 2 to the Fourth Amended and Restated Credit Agreement dated as of June 7, 2019, which updates the provisions relating to the future discontinuance of the London Interbank Offered Rate (“LIBOR”) and sets forth the mechanics for establishing the Secured Overnight Financing Rate as a benchmark replacement rate.
In May 2021, WLFC and its direct, wholly-owned subsidiary Willis Engine Structured Trust VI (“WEST VI”), closed its offering of $336.7 million aggregate principal amount of fixed rate notes (“WEST VI Notes”). The WEST VI Notes were issued in three series, with the Series A Notes issued in an aggregate principal amount of $278.6 million, the Series B Notes issued in an aggregate principal amount of $38.7 million and the Series C Notes issued in an aggregate principal amount of $19.4 million. The WEST VI Notes are secured by, among other things, WEST VI’s direct and indirect ownership interests in a portfolio of 29 aircraft engines and one airframe which WEST VI will acquire from the WLFC pursuant to an asset purchase agreement.
The Series A Notes have a fixed coupon of 3.104%, an expected maturity of approximately eight years and a final maturity date in May 2046, the Series B Notes have a fixed coupon of 5.438%, an expected maturity of approximately eight years and a final maturity date in May 2046 and the Series C Notes have a fixed coupon of 7.385%, an expected maturity of approximately eight years and a final maturity date in May 2046. The Series A Notes were issued at a price of 99.99481% of par, the Series B Notes were issued at a price of 99.99996% of par and the Series C Notes were issued at a price of 99.99869% of par. Principal on the WEST VI Notes is payable monthly to the extent of available cash in accordance with a priority of payments included in the indenture.
The assets of WEST VI are not available to satisfy the Company’s obligations other than the obligations specific to WEST VI. WEST VI is consolidated for financial statement presentation purposes. WEST VI’s ability to make distributions and pay dividends to the Company is subject to the prior payments of its debt and other obligations and WEST VI’s maintenance of adequate reserves and capital. Under WEST VI’s indenture, cash is collected in a restricted account, which is used to service the debt and any remaining amounts, after debt service and defined expenses, are distributed to the Company. Additionally, a portion of maintenance reserve payments and lease security deposits are formulaically accumulated in restricted accounts and are available to fund future maintenance events and to secure lease payments, respectively. The WEST VI indenture requires that a minimum threshold of maintenance reserve and security deposit balances be held in restricted cash accounts.
In May 2021, WLFC repaid an existing note payable that was secured by two engines.
In March 2020, WLFC and its direct, wholly-owned subsidiary Willis Engine Structured Trust V (“WEST V”) (formerly known as Willis Engine Securitization Trust II (“WEST II”)), closed its offering of $366.2 million aggregate principal amount of fixed rate notes (the “WEST V Notes”). The WEST V Notes were issued in three series, with the Series A Notes issued in an aggregate principal

amount of $303.0 million, the Series B Notes issued in an aggregate principal amount of $42.1 million and the Series C Notes issued in an aggregate principal amount of $21.1 million. The WEST V Notes are secured by, among other things, WEST V’s direct and indirect ownership interests in a portfolio of 54 aircraft engines and three airframes, including 25 aircraft engines and three airframes which WEST V acquired from WLFC pursuant to an asset purchase agreement.
The Series A Notes have a fixed coupon of 3.228%, an expected maturity of approximately eight years and a final maturity date of March 15, 2045, the Series B Notes have a fixed coupon of 4.212%, an expected maturity of approximately eight years and a final maturity date of March 15, 2045 and the Series C Notes have a fixed coupon of 6.657%, an expected maturity of approximately eight years and a final maturity date of March 15, 2045. The Series A Notes were issued at a price of 99.99859% of par, the Series B Notes were issued at a price of 99.99493% of par and the Series C Notes were issued at a price of 99.99918% of par. Principal on the WEST V Notes is payable monthly to the extent of available cash in accordance with a priority of payments included in the indenture for the WEST V Notes.
The assets of WEST V are not available to satisfy the Company’s obligations other than the obligations specific to WEST V. WEST V is consolidated for financial statement presentation purposes. WEST V’s ability to make distributions and pay dividends to the Company is subject to the prior payments of its debt and other obligations and WEST V’s maintenance of adequate reserves and capital. Under WEST V’s indenture, cash is collected in a restricted account, which is used to service the debt and any remaining amounts, after debt service and defined expenses, are distributed to the Company. Additionally, a portion of maintenance reserve payments and lease security deposits are formulaically accumulated in restricted accounts and are available to fund future maintenance events and to secure lease payments, respectively. The WEST V indenture requires that a minimum threshold of maintenance reserve and security deposit balances be held in restricted cash accounts.
We recognized a $4.7 million loss on debt extinguishment upon the repayment of the WEST II Series A 2012 term notes in March 2020.
At June 30, 2021, debt obligations consisted of loans totaling $1,911.2 million, net of unamortized issuance costs, payable with interest rates varying between approximately 1.9% 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.
At June 30, 2021, 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 4.50 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 June 30, 2021, 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 June 30, 2021, 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 June 30, 2021:

|  |  | Payment due by period (in thousands)
| Total |  | Less than 1 Year |  | 1-3 Years |  | 3-5 Years |  | More than 5 Years
Debt obligations | $ | 1,932,788 |  |  | $ | 68,414 |  |  | $ | 816,632 |  |  | $ | 124,602 |  |  | $ | 923,140 |

Purchase obligations | 543,994 |  |  | 118,033 |  |  | 425,961 |  |  | — |  |  | — |

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 have purchased three new LEAP-1B engines and are currently committed to purchasing 17 additional new LEAP-1B engines. 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 is 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 May 2021, we entered into a commitment for future maintenance services which are anticipated to cost $24.0 million by 2024.
In June 2021, we entered into definitive agreements for the purchase and leaseback of 20 International Aero Engines AG V2500 aircraft engines. We completed the purchase and leaseback of four of the aircraft engines and anticipate closing on the remaining 16 aircraft engines by September 2021.
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 $70.2 million and $112.0 million by 2030.
We have estimated the interest payments due under debt obligations by applying the interest rates applicable at June 30, 2021 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 for one-month and LIBOR.
Recent Accounting Pronouncements
The most recent adopted accounting pronouncements and accounting pronouncements to be adopted by the Company are described in Note 1 to our Unaudited Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
Our primary market risk exposure is that of interest rate risk. A change in LIBOR 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 June 30, 2021, $688.0 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 $1.9 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 six months ended June 30, 2021 and 2020, 55% and 79%, 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) 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) of 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 June 30, 2021 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 controls over financial reporting. There has been no change in our internal control over financial reporting during our fiscal quarter ended June 30, 2021 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, 2020 filed with the SEC on March 15, 2021, our Quarterly Report on Form 10-Q for the quarter ended March 31, 2021, 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, 2020 and Form 10-Q for the period ended March 31, 2021.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
(a) None.
(b) None.
(c) Issuer Purchases of Equity Securities. Effective December 31, 2018, the Board of Directors approved the renewal of the existing common stock repurchase plan extending the plan through December 31, 2020 and amending the plan to allow for repurchases of up to $60.0 million of the Company’s common stock until such date. Effective December 31, 2020, the Board of Directors approved the renewal of the existing common stock repurchase plan extending the plan through December 31, 2022.
