Operating results for the periods presented are not necessarily indicative of the results that may be expected for the entire year. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been omitted in accordance with the rules and regulations of the SEC; however,SEC. However, we believe that the disclosures are adequate to make the information presented not misleading. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.February 28, 2021.
Effective January 1, 2017, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2016-18, Statement of Cash Flows (Topic 230), Restricted Cash. For the nine months ended September 30, 2017, the Company revised the presentation in our Consolidated Statements of Cash Flows to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents. For the nine months ended September 30, 2016, our Consolidated Statement of Cash Flows reflected: (1) changes in restricted cash related to the sale of flight equipment within investing activities; and (2) changes in restricted cash and restricted cash equivalents related to rents, maintenance payments and security deposits within financing activities. Therefore, the amounts included for the nine months ended September 30, 2016 have been reclassified to conform to the current period presentation.
The Company’s management has reviewed and evaluated all events or transactions for potential recognition and/or disclosure sincesubsequent to the balance sheet date of September 30, 2017May 31, 2021, through the date on which the consolidated financial statements included in this Form 10-Q were issued.
Principles of Consolidation
The consolidated financial statements include the accounts of Aircastle and all of its subsidiaries. Aircastle consolidates foursubsidiaries, including any Variable Interest EntitiesEntity (“VIEs”VIE”) of which Aircastle is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation.
We consolidate VIEsRisk and Uncertainties
In the normal course of business, Aircastle encounters several significant types of economic risk including credit, market, aviation industry and capital market risks. Credit risk is the risk of a lessee’s inability or unwillingness to make contractually required payments and to fulfill its other contractual obligations to Aircastle. Market risk reflects the change in the value of financings due to changes in interest rate spreads or other market factors, including the value of collateral underlying financings. Aviation industry risk is the risk of a downturn in the commercial aviation industry which we have determined that we arecould adversely impact a lessee’s ability to make payments, increase the primary beneficiary. We use judgment when deciding: (a) whether an entity is subject to consolidation as a VIE; (b) whorisk of unscheduled lease terminations and depress lease rates and the variable interest holders are; (c) the potential expected losses and residual returnsvalue of the variable interest holders; and (d) which variable interest holderCompany’s aircraft. Capital market risk is the primary beneficiary. When determining which enterpriserisk that the Company is unable to obtain capital at reasonable rates to fund the primary beneficiary, we consider: (1) the entity’s purpose and design; (2) which variable interest holder has the powergrowth of its business or to direct the activities that most significantly impact the entity’s economic performance; and (3) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. When certain events occur, we reconsider whether we are the primary beneficiary of VIEs. We do not reconsider whether we are a primary beneficiary solely because of operating losses incurred by an entity.

Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. While Aircastle believes that the estimates and related assumptions used in the preparation of the consolidated financial statements are appropriate, actual results could differ from those estimates.
Recent Accounting Pronouncements
On February 25, 2016, the FASB issued Accounting Standards Codification (“ASC”) 842 (“ASC 842”), “Leases,” which replaced the existing guidance in ASC 840, Leases. The accounting for leases by lessors basically remained unchanged from the concepts that existed in ASC 840 accounting. The FASB decided that lessors would be precluded from recognizing selling profit and revenue at lease commencement for any sales-type or direct finance lease that does not transfer control of the underlying asset to the lessee. This requirement aligns the notion of what constitutes a sale in the lessor accounting guidance with that in the forthcoming revenue recognition standard, which evaluates whether a sale has occurred from the customer’s perspective. The standard will be effective for public entities beginning after December 15, 2018. The standard is applied on a modified retrospective approach. We plan to adopt the standard on its required effective date of January 1, 2019. We are evaluating the impact that ASC 842 will have on our consolidated financial statements and related disclosures. We do not believe that the adoption of the standard will significantly impact our existing or potential lessees' economic decisions to lease aircraft.
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. The standard affects entities holding financial assets and net investment in leases that are not accounted for at fair value through net income. The amendments affect loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The standard is applied on a modified retrospective approach. The standard is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted as early as the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are in the process of determining the impact the standard will have on our consolidated financial statements and related disclosures.
In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments. The standard clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. The guidance also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The update should be applied using a retrospective transition method to each period presented. The standard is effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The standard will not have a material impact on our consolidated financial statements and related disclosures.
On May 28, 2014, the FASB and the International Accounting Standards Board (the “IASB”) (collectively, “the Boards”), jointly issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) and related updates. Lease contracts within the scope of ASC 840, Leases, are specifically excluded from ASU No. 2014-09. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. The standard is effective for public entities beginning after December 15, 2017. The standard allows for either “full retrospective” adoption, meaning the standard is applied to all of the periods presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements. We plan to adopt the standard on its required effective date of January 1, 2018, using the modified retrospective approach. We do not expect the impact of this standard to be material to our consolidated financial statements and related disclosures.
In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718), Scope of Modification Accounting. The standard clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Entities will apply the modification accounting guidance if the value, vesting

COVID-19 Pandemic
conditionsCOVID-19 has had an unprecedented negative impact on the aviation sector, resulting in a dramatic slowdown in air traffic. While there have been some improvements in certain markets recently, according to IATA, as of May 31, 2021, air travel was still down to approximately 37% of normal levels and a full recovery to pre-pandemic levels is not expected for several years. Substantially all the world’s airlines have experienced financial difficulties and liquidity challenges, including many of our customers. While we believe long-term demand for air travel will return to historical trends over time, the near-term impacts of COVID-19’s economic shock are material; the extent and duration of those impacts cannot currently be determined.
As the airline industry begins to recover, airlines continue to seek support from their respective governments, raise debt and equity, delay or classificationcancel new aircraft orders, furlough employees, request concessions from lessors, and in certain cases, seek judicial protection. As of July 9, 2021, we have agreed to $111,720 in total deferrals of lease payments with NaN customers. These deferrals have been granted for an average of six to nine months of lease rentals and represent 19% of Lease rental and Direct financing and sales-type lease revenues for the twelve months ended May 31, 2021. Of the total deferrals, $89,400 is included in Accounts receivable or Other assets as of May 31, 2021, with the balance representing future lease payments. Approximately 76% of our total deferrals as of July 9, 2021, have been agreed to as part of broader lease restructurings. These generally include term extensions, better security packages, or other valuable consideration in exchange for near-term economic concessions. Some have repayment terms that extend beyond twelve months and in a limited number of situations, we have agreed to broader lease restructurings that do not include the full repayment of all of lease payments.
If air traffic remains depressed and if our customers are unable to obtain sufficient funds from private, governmental or other sources, we may need to grant additional deferrals to some of our customers or extend the period of repayment for deferrals we have already made. We may ultimately not be able to collect all the amounts we have deferred.
As of July 9, 2021, 6 of our customers are subject to judicial insolvency proceedings or similar protection. These customers lease 22 aircraft, which represent 13% of our net book value of flight equipment (including Flight equipment held for lease and Net investment in leases, or “net book value”) and 11% of our Lease rental and direct financing and sales-type lease revenue as of and for the twelve months ended May 31, 2021. LATAM, our second largest customer, is included in this group and represents 8% of our net book value of flight equipment and 7% of our Lease rental revenue as of and for the twelve months ended May 31, 2021. We are actively engaged in these judicial proceedings to protect our economic interests. However, the outcome of these proceedings is uncertain and could result in these customers negotiating reductions in aircraft lease rentals, rejecting their leases or taking other actions that could adversely impact us or the value of our aircraft. Based on historic experience, the judicial process can take up to twelve to eighteen months to be resolved. As a result of these proceedings, the recognition of lease rental revenue for certain customers may be done on a cash basis of accounting rather than the accrual method depending on the customers’ lease security arrangements.
Lease Revenue Recognition
We lease flight equipment under net operating leases with lease terms typically ranging from three to seven years. We generally do not offer renewal terms or purchase options in our leases, although certain of our operating leases allow the lessee the option to extend the lease for an additional term. Operating leases with fixed rentals and step rentals are recognized on a straight-line basis over the term of the award changes. initial lease, assuming no renewals.
In addition, when applicable, disclosurecertain instances, we may provide lease concessions to customers, generally in the form of lease rental deferrals. While these deferral arrangements affect the timing of lease rental payments, the total amount of lease rental payments required over the lease term is generally the same as that which was required under the original lease agreement. We account for the deferrals as if no modifications to indicatethe lease agreements were made and record the deferred rentals as a receivable within Other assets.
Should we determine that compensation expense hasthe collectability of rental payments is no longer probable (including any deferral thereof), we will recognize lease rental revenue using a cash basis of accounting rather than an accrual method. In the

period we conclude that collection of lease payments is no longer probable, we recognize any difference between revenue amounts recognized to date under the accrual method and payments that have been collected from the lessee, including security deposit amounts held, as a current period adjustment to lease rental revenue.
Impairment of Flight Equipment
We perform an annual recoverability assessment of all aircraft in our fleet, on an aircraft-by-aircraft basis. A recoverability assessment is also performed whenever events or changes in circumstances, or indicators, suggest that the carrying amount or net book value of an asset may not changed.be recoverable. Indicators may include, but are not limited to, a significant lease restructuring or early lease termination, significant change in aircraft model’s storage levels, the introduction of newer technology aircraft or engines, an aircraft type is no longer in production or a significant airworthiness directive is issued. When we perform a recoverability assessment, we measure whether the estimated future undiscounted net cash flows expected to be generated by the aircraft exceed its net book value. The updateundiscounted cash flows consist of cash flows from currently contracted lease rental and maintenance payments, future projected lease rates and maintenance payments, transition costs, estimated down time, and estimated residual or scrap values for an aircraft. In the event that an aircraft does not meet the recoverability test, the aircraft will be adjusted to fair value, resulting in an impairment charge. See Note 2 – Fair Value Measurements.
Management develops the assumptions used in the recoverability analysis based on current and future expectations of the global demand for a particular aircraft type and historical experience in the aircraft leasing market and aviation industry, as well as information received from third party industry sources. The factors considered in estimating the undiscounted cash flows are impacted by changes in future periods due to changes in projected lease rental and maintenance payments, residual values, economic conditions, technology, airline demand for a particular aircraft type and other factors.
We continue to closely monitor the impact of COVID-19 on our customers, air traffic, lease rental rates, and aircraft valuations, and have and will continue to perform additional customer and aircraft specific reviews should changes in facts and circumstances arise that may impact the recoverability of our aircraft. We will focus on our customers that have entered judicial insolvency proceedings and any additional customers that may become subject to similar-type proceedings, aircraft with near-term lease expirations, and certain aircraft variants that are more susceptible to the impact of COVID-19 and value deterioration.
Recent Accounting Pronouncements
In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2020-04, Reference Rate Reform Topic 848 (“ASC 848”), in response to the market transition from the LIBOR and other interbank offered rates (“IBORs”) to alternative reference rates. U.S. GAAP requires entities to evaluate whether a contract modification, such as the replacement or change of a reference rate, results in the establishment of a new contract or continuation of an existing contract. ASC 848 allows an entity to elect not to apply certain modification accounting requirements to contracts affected by reference rate reform. The standard provides this temporary election through December 31, 2022, and cannot be applied using a prospective transition method to each period presented.contract modifications that occur after December 31, 2022. Reference rate reform will primarily impact our lease and debt arrangements for which floating-rate lease rentals and interest expense are based on LIBOR. As of May 31, 2021, less than 1% of our fleet have floating-rate lease rentals and, for the three months ended May 31, 2021, 5% of our interest expense was derived from floating-rate debt which is referenced to LIBOR. We have not adopted ASC 848 and are currently evaluating the election available to us under the standard.
Effective, March 1, 2021, the Company adopted FASB ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes. The standardguidance aims to simplify the accounting for income taxes by removing certain exceptions to the general principles within the current guidance and by clarifying and amending the current guidance. The guidance is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2017, including interim periods within those fiscal years. Early2020. This adoption is permitted. The standard willdid not have a material impact on our consolidated financial statementsstatements.

Note 2. Fair Value Measurements
Fair value measurements and disclosures require the use of valuation techniques to measure fair value that maximize the use of observable inputs and minimize use of unobservable inputs. These inputs are prioritized as follows:
Level 1: Observable inputs such as quoted prices in active markets for identical assets or liabilities.
Level 2: Inputs other than quoted prices included within Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities or market corroborated inputs.
Level 3: Unobservable inputs for which there is little or no market data and which require us to develop our own assumptions about how market participants price the asset or liability.
The valuation techniques that may be used to measure fair value are as follows:
The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.
The income approach uses valuation techniques to convert future amounts to a single present amount based on current market expectation about those future amounts.
The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost).
The following tables set forth our financial assets as of September 30, 2017May 31, 2021 and December 31, 2016February 28, 2021 that we measured at fair value on a recurring basis by level within the fair value hierarchy. Assets measured at fair value are classified in their entirety based on the lowest level of input that is significant to their fair value measurement.

Our cash and cash equivalents, along with ourand restricted cash and cash equivalents balances, consist largely of money market securities that are considered to be highly liquid and easily tradable. These securities are valued using inputs observable in active markets for identical securities and are therefore classified as Level 1 within ourthe fair value hierarchy. Our interest rate derivative included in Level 2 consists of United States dollar-denominated interest rate cap, and the fair value is based on market comparisons for similar instruments. We also considered the credit rating and risk of the counterparty providing the interest rate cap based on quantitative and qualitative factors.
For the three and nine months ended September 30, 2017 and the year ended DecemberMay 31, 2016,2021, we had no0 transfers into or out of Level 3.
We measure the fair value of certain assets and liabilities on a non-recurring basis, when U.S. GAAP requires the application of fair value, including events or changes in circumstances that indicate that the carrying amounts of these assets may not be recoverable. Assets subject to these measurements include our investmentsinvestment in unconsolidated joint ventures and aircraft. We account for our investments in unconsolidated joint ventures under the equity method of accounting and record impairment when its fair value is less than its carrying value. We record aircraft at fair value when we determine the carrying value may not be recoverable. Fair value measurements for aircraft in impairment tests are based on the average of the market approach that uses Level 2 inputs, which include third party appraisal data and an income approach whichthat uses Level 3 inputs, which include the Company’s assumptions and appraisal data as to future cash proceeds from leasing and selling aircraft.aircraft discounted using the Company’s weighted average cost of capital.
We account for our investment in unconsolidated joint ventures under the equity method of accounting. Investments are recorded at cost and are adjusted by undistributed earnings and losses and the distributions of dividends and capital. These investments are also reviewed for impairment whenever events or changes in circumstances indicate the fair value is less than its carrying value and the decline is other-than-temporary.

We have and will focus on our customers that have entered judicial insolvency proceedings and any additional customers that may become subject to similar-type proceedings, aircraft with near-term lease expirations, and certain aircraft variants that are more susceptible to the impact of the COVID-19 pandemic and value deterioration.
The recoverability assessment is a comparison of the carrying value of each aircraft to its undiscounted expected future cash flows. We develop the assumptions used in the recoverability assessment, including those relating to current and future demand for each aircraft type, based on management’s experience in the aircraft leasing industry, as well as information received from third-party sources. Estimates of the undiscounted cash flows for each aircraft type are impacted by changes

in contracted and future expected lease rates, residual values, expected scrap values, economic conditions and other factors.
Management believes that the net book value of each aircraft is currently supported by the estimated future undiscounted cash flows expected to be generated by that aircraft, and accordingly, no aircraft were impaired as a consequence of our annual recoverability assessment. However, ifIf our estimates or assumptions change, including those related to our customers that have entered judicial insolvency proceedings, we may revise our cash flow assumptions and record future impairment charges. While we believe that the estimates and related assumptions used in the annualour recoverability assessmentassessments are appropriate, actual results could differ from those estimates.
Financial Instruments
Our financial instruments, other than cash, consist principally of cash equivalents, restricted cash and cash equivalents, accounts receivable, accounts payable and amounts borrowed under financings and interest rate derivatives.financings. The fair value of cash, cash equivalents, restricted cash and cash equivalents, accounts receivable and accounts payable approximates the carrying value of these financial instruments because of their short-term nature.
The fair value of our senior notes is estimated using quoted market prices. The fair values of all our other financings are estimated using a discounted cash flow analysis, based on our current incremental borrowing rates for similar types of borrowing arrangements.

Note 6. Variable Interest Entities
Aircastle consolidates four VIEs of which it is the primary beneficiary. The operating activities of these VIEs are limited to acquiring, owning, leasing, maintaining, operating and, under certain circumstances, selling the six aircraft discussed below.
ECA Financings
Aircastle, through various subsidiaries, each of which is owned by a charitable trust (such entities, collectively the “Air Knight VIEs”), has entered into six different twelve-year term loans, which are supported by guarantees from Compagnie Française d'Assurance pour le Commerce Extérieur, (“COFACE”), the French government sponsored export credit agency (“ECA”). We refer to these COFACE-supported financings as “ECA Financings.”
Aircastle is the primary beneficiary of the Air Knight VIEs, as we have the power to direct the activities of the VIEs that most significantly impact the economic performance of such VIEs and we bear the significant risk of loss and participate in gains through a finance lease. The activity that most significantly impacts the economic performance is the leasing of aircraft of which our wholly owned subsidiary is the servicer and is responsible for managing the relevant aircraft. There is a cross collateralization guarantee between the Air Knight VIEs. In addition, Aircastle guarantees the debt of the Air Knight VIEs.
The only assets that the Air Knight VIEs have on their books are financing leases that are eliminated in the consolidated financial statements. The related9 aircraft with a net book value as of September 30, 2017 of $417,439, were included in our flight equipment held for lease. The consolidated debt outstanding, net of debt issuance costs, of the Air Knight VIEs as of September 30, 2017 is $230,858.$308,640 at May 31, 2021.

In applying the two-class method, distributed and undistributed earnings are allocated to both common shares and restricted common shares based on the total weighted-average shares outstanding during the period.

OVERVIEW
Aircastle acquires, leases, and sells commercial jet aircraft to airlines throughout the world. As of September 30, 2017,May 31, 2021, we owned and managed on behalf of our joint ventures 205259 aircraft leased to 7177 lessees located in 3843 countries. Our aircraft are managed by an experienced team based in the United States, Ireland and Singapore. Our aircraft are generally subject to net leases whereby the lessee is generally responsible for maintaining the aircraft and paying operational, maintenance and insurance costs. InHowever, in many cases however, we are obligated to pay a specified portion of specified maintenance or modification costs. As of September 30, 2017,May 31, 2021, the net book value of our flight equipment (including flight equipment held for lease and net investment in finance and sales-type leases, or "net“net book value"value”) was $5.98$6.58 billion compared to $6.51$6.69 billion at December 31, 2016.February 28, 2021. Our total revenues, net loss and net incomeAdjusted EBITDA were $165.8 million, $9.8 million and $148.3 million for the three and nine months ended September 30, 2017 were $191.4May 31, 2021, and $282.5 million, $26.5 million and $57.4$268.2 million and $619.2 million and $92.8 million,for the three months ended May 31, 2020, respectively.
GrowthHistorically, growth in commercial air traffic is broadlyhas been correlated with world economic activity. In recent years, it has been expandingPrior to the COVID-19 pandemic, commercial air traffic growth expanded at a rate one and a half1.3 to two2 times that of global GDP growth. TheThis expansion of air travel has driven a risethe growth in the world aircraft fleet. Therefleet; and there are currently approximately 20,00024,000 commercial mainline passenger and freighter aircraft in operation worldwide. Thisthe world fleet is expectedtoday. Aircraft leasing companies own approximately 52% of the world’s commercial jet aircraft. Under normal circumstances, we would expect the global fleet to continue expanding at threea two to four percent average annual rate overrate.
COVID-19 has had an unprecedented negative impact on the next twentyaviation sector, resulting in a dramatic slowdown in air traffic. While there have been some improvements in certain markets recently, according to IATA, as of May 31, 2021, air travel was still down to approximately 37% of normal levels and a full recovery to pre-pandemic levels is not expected for several years. Aircraft leasing companies own approximately 41% ofSubstantially all the world’s commercial jet aircraft.
Notwithstanding the sector’sairlines have experienced financial difficulties and liquidity challenges, including many of our customers. While we believe long-term growth, the aviation markets have been, and are expected to remain, subject to economic variability due to changes in macroeconomic variables such as fuel price levels and foreign exchange rates. The aviation industry is also susceptible to external shocks, such as regional conflicts and terrorist events. Mitigating this risk is the portability of the assets, allowing aircraft to be redeployed to locations where demand is higher.
Air traffic data for the past several years has shown strong passenger market growth.  According to the International Air Transport Association, during the first eight months of 2017, global passenger traffic increased 7.9% compared to the same period in 2016. During the first eight months of 2017, air cargo traffic increased 10.5% compared to the same period in 2016, and capacity increased 3.8%, resulting in an increase in load factors to 43.3%.
Demand for air travel varies considerably by region. Emerging market economies have generally been experiencing greater increases in air traffic, driven by rising levels of per capita income. Air traffic growth is also being driven by the proliferation of low cost carriers, which have stimulated demand through lower prices. Mature markets, such as North America and Western Europe, are likelywill return to grow more slowly in tandem with their economies. Persian Gulf-based Emirates, Qatar Airways and Etihad Airways are also showing signs of reaching maturity. Airlines operating in areas with political instability or weakening economies are under pressure, and their near-term outlook is more uncertain. On balance, we believe air travel will increasehistorical trends over time, the near-term impacts of COVID-19’s economic shock are material; the extent and as a result, we expect demand for modern aircraft willduration of those impacts cannot currently be determined.
As the airline industry begins to recover, airlines continue to remain strong over the long-term.
Low fuel prices and interest rates have had a substantial effect on our industry. The price of oil dropped by $67 to $36 per barrel in the four years prior to December 2015. This allowed airlines to reduce ticket prices and stimulate aircraft traffic while retaining enough of this benefit to achieve record profit levels. A low interest rate environment and the strong overall performance of the aircraft financing sector attracted significant new capital, increasing competition for new investments. The downward trend in fuel prices and interest rates appears to have ended as fuel prices started rising in 2016. In 2017, the price of fuel has averaged approximately $50 per barrel. Likewise, interest rates have started to rise in the U.S., with Federal Reserve guidance suggesting multiple future rate hikes subsequent to the December 2016 increase in the Federal Funds rate.
Capital availability for aircraft has varied over time, and we consider this variability to be a basic characteristic of our business. If pursued properly, this represents an important source of opportunity. Bothseek support from their respective governments, raise debt and equity, marketsdelay or cancel new aircraft orders, furlough employees, request concessions from lessors, and in certain cases, seek judicial protection. As of July 9, 2021, we have improved globally overagreed to $111.7 million in total deferrals of lease payments with 22 customers. These deferrals have been granted for an average of six to nine months of lease rentals and represent 19% of Lease rental and Direct financing and sales-type lease revenues for the past several yearstwelve months ended May 31, 2021. Of the total deferrals, $89.4 million is included in Accounts receivable or Other assets as of May 31, 2021, with the recovery from the global financial crisis. Strong U.S. debt capital market conditions benefited borrowers by permitting accessbalance representing future lease payments. Approximately 76% of our total deferrals as of July 9, 2021, have been agreed to financing at historic lows while higher feesas part of broader lease restructurings. These generally include term extensions, better security packages, or other valuable consideration in exchange for near-term economic concessions. Some have driven down ECA demand. Recently, ECA availability has been curtailed, both in the U.S.repayment terms that extend beyond twelve months and in Europe, duea limited number of situations, we have agreed to political issuesbroader lease restructurings that do not include the full repayment of all of lease payments.
If air traffic remains depressed and an investigation into possible irregularities, respectively. Commercial bank debt continuesif our customers are unable to play a critical role for aircraft finance, althoughobtain sufficient funds from private, governmental or other sources, we believe regulatory pressures may limit its role over time.
While financial markets conditions are currently attractive, heightened volatility stemming from global growth concerns and various geopolitical issues may increase capital costs and limit availability going forward. We believe these market forces should generate attractive new investment and trading opportunities for which we are well placedneed to capitalize given our accessgrant additional deferrals to different financing sources, our limited capital commitments and our reputation as a reliable trading partner.

Over the longer term, our strategy is to achieve an investment grade credit rating, which we believe will reduce our borrowing costs and enable more reliable access to debt capital throughout the business cycle.
We believe our business approach is differentiated from those of other large leasing companies. Our investment strategy is to seek out the best risk-adjusted return opportunities across the commercial jet market, so our acquisition targets and growth rates will vary with market conditions. We prefer to have capital resources available to capture investment opportunities that arise in the context of changing market circumstances. As such, we limit large, long-term capital commitments and are therefore much less reliant on orders for new aircraft from aircraft manufacturers as a source of new investments.
We plan to grow our business and profits over the long-term while maintaining a countercyclical orientation, a bias towards limiting long-dated capital commitments and a conservative and flexible capital structure. Our business strategy entails the following elements:
Pursuing a disciplined and differentiated investment strategy. In our view, aircraft values change in different ways over time. We carefully evaluate investments across different aircraft models, ages, lessees and acquisition sources and re-evaluate these choices as market conditions and relative investment values change. We believe the financing flexibility offered through unsecured debt and our team’s experience with a wide range of asset types enables our value oriented strategy and provides us with a competitive advantage. We view orders from equipment manufacturers to be partsome of our investment opportunity set, but choose to limit long term capital commitments unless we believe there is an adequate return premium to compensatecustomers or extend the period of repayment for risks and opportunity costs. This approach sets us apart from most other large aircraft leasing companies.
Originating investments from many different sources across the globe.Our strategy is to seek out worthwhile investments by leveraging our team’s wide range of contacts around the world. We utilize a multi-channel approach to sourcing acquisitions and have purchased aircraft from a large number of airlines, lessors, original equipment manufacturers, lenders and other aircraft owners. Since our formation in 2004,deferrals we have acquiredalready made. We may ultimately not be able to collect all the amounts we have deferred.
As of July 9, 2021, six of our customers are subject to judicial insolvency proceedings or similar protection. These customers lease 22 aircraft, from 86 different sellers.
Selling assets when attractive opportunities arise. We sell assets with the aimwhich represent 13% of realizing profitsour net book value of flight equipment (including Flight equipment held for lease and reinvesting proceeds when a sale generates the greatest expected cash flowNet investment in leases, or when more accretive investments are available. We also use asset sales for portfolio management purposes, such as reducing lessee specific concentrations“net book value”) and lowering residual value exposures to certain aircraft types.
Maintaining efficient access to capital from a wide set11% of sources while targeting an investment grade credit rating. We believe the aircraft investment market is influenced by the business cycle. Our strategy is to increase our purchase activity when prices are lowLease rental and to emphasize asset sales when competition for assets is high. To implement this approach, we believe it is important to maintain access to a wide variety of financing sources. Our objective is to improve our corporate credit ratings to an investment grade level by maintaining strong portfolio and capital structure metrics while achieving a critical size through accretive growth. We believe improving our credit rating will not only reduce our borrowing costs but also facilitate more reliable access to both secured and unsecured debt capital throughout the business cycle.
Leveraging our strategic relationships. We intend to capture the benefits provided through the extensive global contacts and relationships maintained by Marubeni, which is our biggest shareholder and one of the largest Japanese trading companies. Marubeni has already enabled greater access to Japanese-baseddirect financing and helped sourcesales-type lease revenue as of and developfor the twelve months ended May 31, 2021.

We are actively engaged in these judicial proceedings to protect our economic interests. However, the outcome of these proceedings is uncertain and could result in these customers negotiating reductions in aircraft leased to premier airlines, providing Aircastle with increased access to this market sector and to these customers.

on a cash basis of accounting rather than the accrual method depending on the customers’ lease security arrangements.
We believe that our long-standing business strategy of maintaining conservative leverage, limiting long-term financial commitments and focusing our portfolio on more liquid narrow-body aircraft will enable us to manage through the COVID-19 crisis. Our portfolio of primarily mid-life, narrow-body aircraft should remain attractive relative to new technology aircraft due to their lower capital costs in an environment of tight airline margins and low fuel prices.
In addition, we believe that we have sufficient liquidity to meet our contractual obligations over the next twelve months and as of July 1, 2021, total liquidity of $2.88 billion includes $1.38 billion of undrawn credit facilities, $1.02 billion of unrestricted cash, $103 million of contracted asset sales and $375 million of projected operating cash flows through June 30, 2022. As of May 31, 2021, we have commitments to acquire 23 aircraft for $779.4 million between 2021-2025.
We also believe our platform and strong operating track record. We believe our team’s capabilitiespersonnel position us to effectively manage through the COVID-19 crisis and will enable us to take advantage of new investment opportunities when they arise. Our Company employs a team of experienced senior professionals with extensive industry and financial experience. Our leadership team members have an average of more than twenty years of relevant industry experience, including managing through prior downturns in the aviation industry, like the 2008 global aircraft leasing market places us in a favorable position to source and manage new income-generating activities. We intend to continue to focus our efforts in areas where we believe we have competitive advantages, including new direct investments as well as ventures with strategic business partners.
Intending to pay quarterly dividends to our shareholders based on the Company’s sustainable earnings levels. Aircastle has paid dividends each quarter since our initial public offering in 2006. On August 4, 2017, our Board of Directors declared a regular quarterly dividend of $0.26 per common share, or an aggregate of $20.5 million for the three months ended September 30, 2017, which was paid on September 15, 2017 to holders of record on August 31, 2017. These dividends may not be indicative of the amount of any future dividends. Our ability to

pay quarterly dividends will depend upon many factors, including those as described in Item 1A. “Risk Factors” and elsewhere in our 2016 Annual Report on Form 10-K.
Revenues
Our revenues are comprised primarily of operating lease rentals on flight equipment held for lease, revenue from retained maintenance payments related to lease expirations, lease termination payments, lease incentive amortization and interest recognized from finance and sales-type leases.
Typically, our aircraft are subject to net leases whereby the lessee pays lease rentals and is generally responsible for maintaining the aircraft and paying operational, maintenance and insurance costs arising during the term of the lease. Our aircraft lease agreements generally provide for the periodic payment of a fixed amount of rent over the life of the leasefinancial crisis and the amount of the contracted rent will depend upon the type, age, specification and condition of the aircraft and market conditions at the time the lease is committed. The amount of rent we receive will depend on a number of factors, including the creditworthiness of our lessees and the occurrence of restructurings and defaults. Our lease rental revenues are also affected by the extent to which aircraft are off-lease and our ability to remarket aircraft that are nearing the end of their leases in order to minimize their off-lease time. Our success in re-leasing aircraft is affected by market conditions relating to our aircraft and by general industry conditions and trends. An increase in the percentage of off-lease aircraft or a reduction in lease rates upon remarketing would negatively impact our revenues.September 11, 2001 terror attacks.
Under an operating lease, the lessee will be responsible for performing maintenance on the relevant aircraft and will typically be required to make payments to us for heavy maintenance, overhaul or replacement of certain high-value components of the aircraft. These maintenance payments are based on hours or cycles of utilization or on calendar time, depending upon the component, and would be made either monthly in arrears or at the end of the lease term. For maintenance payments made monthly in arrears during a lease term, we will typically be required to reimburse all or a portion of these payments to the lessee upon their completion of the relevant heavy maintenance, overhaul or parts replacement. We record maintenance payments paid by the lessee during a lease as accrued maintenance liabilities in recognition of our obligation in the lease to refund such payments, and therefore we do not recognize maintenance revenue during the lease. Maintenance revenue recognition would occur at the end of a lease, when we are able to determine the amount, if any, by which reserve payments received exceed the amount we are required under the lease to reimburse to the lessee for heavy maintenance, overhaul or parts replacement. The amount of maintenance revenue we recognize in any reporting period is inherently volatile and is dependent upon a number of factors, including the timing of lease expiries, including scheduled and unscheduled expiries, the timing of maintenance events and the utilization of the aircraft by the lessee.
Many of our leases contain provisions which may require us to pay a portion of the lessee’s costs for heavy maintenance, overhaul or replacement of certain high-value components. We account for these expected payments as lease incentives, which are amortized as a reduction of revenue over the life of the lease. We estimate the amount of our portion for such costs, typically for the first major maintenance event for the airframe, engines, landing gear and auxiliary power units, expected to be paid to the lessee based on assumed utilization of the related aircraft by the lessee, the anticipated cost of the maintenance event and the estimated amounts the lessee is responsible to pay.
This estimated lease incentive is not recognized as a lease incentive liability at the inception of the lease. We recognize the lease incentive as a reduction of lease revenue on a straight-line basis over the life of the lease, with the offset being recorded as a lease incentive liability which is included in maintenance payments on the balance sheet. The payment to the lessee for the lease incentive liability is first recorded against the lease incentive liability and any excess above the lease incentive liability is recorded as a prepaid lease incentive asset which is included in other assets on the balance sheet and continues to amortize over the remaining life of the lease.

2017Fiscal Year 2021 Lease Expirations and Lease Placements
At September 30, 2017,May 31, 2021, the Company had seventeen off-lease aircraft and 22 aircraft with scheduled lease expirations in fiscal 2021.

Operating Expenses

Operating expenses are comprised of depreciation of flight equipment held for lease, interest expense, selling, general and administrative expenses, aircraft impairment charges and maintenance and other costs. Because our operating lease terms generally require the lessee to pay for operating, maintenance and insurance costs, our portion of maintenance and other costs relating to aircraft reflected in our statement of income primarily relates to expenses for unscheduled lease terminations.

Income Tax Provision
We obtained an assurance from the Minister of Finance of Bermuda under the Exempted Undertakings Tax Protection Act 1966 that, in the event any legislation is enacted in Bermuda imposing any tax computed on profits or income, or computed on any capital asset, gain or appreciation or any tax in the nature of estate duty or inheritance tax, such tax shall not, until March 2035, be applicable to us or to any of our operations or to our shares, debentures or other obligations except insofar as such tax applies to persons ordinarily resident in Bermuda or to any taxes payable by us in respect of real property owned or leased by us in Bermuda. Consequently, the provision for income taxes recorded relates to income earned by certain subsidiaries of the Company which are located in, or earn income in, jurisdictions that impose income taxes, primarily Ireland, Singapore and the United States.
All of our aircraft-owning subsidiaries that are recognized as corporations for U.S. tax purposes are non-U.S. corporations. These non-U.S. subsidiaries generally earn income from sources outside the United States and typically are not subject to U.S. federal, state or local income taxes, unless they operate within the U.S., in which case they may be subject to federal, state and local income taxes. The aircraft owning subsidiaries resident in Ireland, Mauritius and Singapore are subject to tax in those respective jurisdictions.
We have a U.S.-based subsidiary which provides management services to our non-U.S. subsidiaries and is subject to U.S. federal, state and local income taxes. We also have Ireland and Singapore based subsidiaries which provide management services to our non-U.S. subsidiaries and are subject to tax in those respective jurisdictions.
Acquisitions and Sales
During the first ninethree months of 2017,ended May 31, 2021, we acquired 28two aircraft for $635.1$63.9 million. As of OctoberJuly 9, 2021, we acquired one additional aircraft. At May 31, 2017, we have acquired 37 aircraft for approximately $760 million. At September 30, 2017,2021, we had commitments to acquire 64 additional23 aircraft for $1.80 billion, including$779.4 million. Of this amount, approximately $134.5 million represents commitments for the acquisitionremainder of 25 new E-Jet E2 aircraft from Embraer, which are scheduled to deliver in 2019 tofiscal year 2021. As of October 31, 2017, we have commitments to acquire 55 aircraft for $1.68 billion.
During the first ninethree months of 2017,ended May 31, 2021, we sold 29three aircraft and other flight equipment for $765.0net proceeds of $63.4 million, which resulted in aand recognized net gaingains on sales of $35.9$9.0 million. During October 2017,As of July 9, 2021, we have sold one narrow-body aircraft and one classic narrow-bodyadditional aircraft.

Finance
We believe thatoperate in a capital-intensive industry and have a demonstrated track record of raising substantial amounts of capital over the last sixteen years. Since our inception in late 2004, we have raised $2.1 billion in equity capital from private and public investors. We also raised $18.9 billion in debt capital from a variety of sources including export credit agency-backed debt, commercial bank debt, the aircraft securitization markets and the unsecured bond market. The diversity and global nature of our financing sources demonstrates our ability to adapt to changing market conditions and seize new growth opportunities.
We intend to fund new investments through cash on hand, funds generated from operations, maintenance payments received from lessees, secured and other funds generated from operations, securedunsecured borrowings for aircraft, borrowings underdraws on our revolving credit facilities and other borrowings and proceeds from any future aircraft sales will be sufficient to satisfy our liquidity and capital resource needs over the next twelve months.sales. We may repay all or a portion of such borrowings from time to time with the net proceeds from subsequent long-term debt financings, additional equity offerings or cash generated from operations and asset sales. Therefore, our ability to execute our business strategy, particularly the acquisition of additional commercial jet aircraft or other aviation assets, depends to a significant degree on our ability to obtain additional debt and equity capital on terms we deem attractive.

As more fully described above under “Revenues,” lease incentives represent our estimated portion of the lessee’s cost for heavy maintenance, overhaul or replacement of certain high-value components, which are amortized over the life of the related lease. As we enter into new leases, the amortization of lease incentives generally increases and, conversely, if a related lease terminates, the related unused lease incentive liability will reduce the amortization of lease incentives. The increasedecrease in amortization of lease incentivespremiums of $1.9$2.2 million for the three months ended September 30, 2017,May 31, 2021 as compared to the same period in 2016,three months ended May 31, 2020, was primarily attributable to the reversal of lease incentives associated with one freighter aircraft due to changes in estimate and the reclassification of one aircraft from an operatingearly lease to a finance lease.terminations.

During the third quarter of 2016, we recorded gains totaling $7.8 million and losses totaling $7.9 million, primarily due to a loss of $5.2 million for a wide-body aircraft’s lease extension classified as a sales-type lease.
Income tax provision
Our provision for income taxes for the three months ended September 30, 2017 and 2016 was $6.2 million and $2.5 million, respectively. Income taxes have been provided based on the applicable tax laws and rates of those countries in which operations are conducted and income is earned, primarily Ireland, Singapore and the United States. The increase in our income tax provision of approximately $3.7 million for the three months endedSeptember 30, 2017, as compared to the same period in 2016, wasthree months ended May 31, 2020, primarily attributable to changes in operating income subject to tax in Ireland, Singapore, the United Stateshigher costs for scheduled and other jurisdictions.unscheduled transitions.
All of our aircraft-owning subsidiaries that are recognized as corporations for U.S. tax purposes are non-U.S. corporations. These non-U.S. subsidiaries generally earn income from sources outside the United States and typically are not subject to U.S. federal, state or local income taxes unless they operate within the U.S., in which case they may be subject to federal, state and local income taxes. The aircraft owning subsidiaries resident in Ireland, Mauritius and Singapore are subject to tax in those respective jurisdictions.
We have a U.S.-based subsidiary which provides management services to our non-U.S. subsidiaries and is subject to U.S. federal, state and local income taxes. In addition, we have Ireland and Singapore based subsidiaries which provide management services to our non-U.S. subsidiaries and are subject to tax in those respective jurisdictions.
The Company received an assurance from the Bermuda Minister of Finance that it would be exempted from local income, withholding and capital gains taxes until March 2035. Consequently, the provision for income taxes recorded relates to income earned by certain subsidiaries of the Company which are located in, or earn income in, jurisdictions that impose income taxes, primarily the United States and Ireland.

Maintenance revenue. For the nine months ended September 30, 2017, we recorded $55.7 million of maintenance revenue primarily due to the transition of four narrow-body, four wide-body and one freighter aircraft for $50.6 million. For the same period in 2016, we recorded $20.6 million of maintenance revenue from one scheduled lease termination for $6.9$8.3 million and maintenance reserves taken into income for three freighter aircraft and one wide-body aircraft totaling $13.2 million.
Other revenue. For the nine months ended September 30, 2017, we recorded $4.5 million of other revenue, primarily from fees earned from two lessees in connection with the early terminations of two leases. For the same period in 2016, we recorded $2.4 million of other revenue.
Operating expenses
Total operating expenses increased by $60.6 million for the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016.
Depreciation expense decreased by $0.5 million for the nine months ended September 30, 2017 as compared to the same period in 2016. The decrease is primarily the result of lower depreciation of $44.0 million due to 55 aircraft sold.
This decrease was partially offset by increases of:
$40.2 million due to 64 aircraft acquisitions, and;
$3.3 million due to changes in asset lives, residual values and other changes.

We also performed aircraft-specific analyses where there werecontinue to closely monitor the impact of COVID-19 on our customers, air traffic, lease rental rates, and aircraft valuations, and have and will continue to perform additional customer and aircraft specific reviews should changes in facts and circumstances such as approaching lease expirations. Other thanarise that may impact the transactional impairments discussed above, no other impairments were recorded as a resultrecoverability of our annual recoverability assessment.aircraft. We have and will focus on our customers that have entered judicial insolvency proceedings and any additional customers that may become subject to similar-type proceedings, aircraft with near-term lease expirations, and certain aircraft variants that are more susceptible to the impact of the COVID-19 pandemic and value deterioration.
The recoverability assessment is a comparison of the carrying value of each aircraft to its undiscounted expected future cash flows. We develop the assumptions used in the recoverability assessment, including those relating to current and future demand for each aircraft type, based on management’s experience in the aircraft leasing industry, as well as information received from third-party sources. Estimates of the undiscounted cash flows for each aircraft type are impacted by changes in contracted and future expected lease rates, residual values, expected scrap values, economic conditions and other factors.
Management believes that the net book value of each aircraft is currently supported by the estimated future undiscounted cash flows expected to be generated by that aircraft, and accordingly, no aircraft were impaired as a consequence of our annual recoverability assessment. However, if

If our estimates or assumptions change, including those related to our customers that have entered judicial insolvency proceedings, we may revise our cash flow assumptions and record future impairment charges. While we believe that the estimates and related assumptions used in the annualour recoverability assessmentassessments are appropriate, actual results could differ from those estimates.

At September 30, 2017, we considered one Boeing 747-400 production freighter model and five Airbus A330 passenger aircraft with a total net book value of $407.3 million, or 6.8%, to be more susceptible to failing our recoverability assessments due to their sensitivity to changes in contractual cash flows, future cash flow estimates and aircraft residual or scrap values.

various forms of borrowing secured by our aircraft, including bank term facilities, limited recourse securitization financings, and ECA-backed financings for new aircraft acquisitions;
unsecured indebtedness, including our current unsecured revolving credit facilities, term loan and senior notes;
asset sales; and
sales of common and preferred shares.
Going forward, we expect to continue to seek liquidity from these sources and other sources, subject to pricing and conditions we consider satisfactory.
During the first ninethree months of 2017,ended May 31, 2021, we met our liquidity and capital resource needs with $393.5$70.0 million of cash flow from operations $500.0 million in gross proceeds from the issuance of our Senior Notes due 2024 and $765.0$63.4 million of cash from the sale of aircraft sales.and other flight equipment.
As of September 30, 2017,May 31, 2021, the weighted-average maturity of our secured and unsecured debt financings was 3.93.5 years and we arewere in compliance with all applicable covenants.
We have agreed to defer lease payments with certain of our airline customers. As of July 9, 2021, we have agreed to defer approximately $111.7 million of lease payments with 22 airlines, which they are obligated to repay over time. If air traffic remains depressed over an extended period and if our customers are unable to obtain sufficient funds from private, government or other sources, we may need to extend further deferrals to some of our other customers or to extend the deferrals we have previously granted. We may ultimately be unable to collect all the amounts we have deferred. As of May 31, 2021, we hold $78.3 million in security deposits, $524.0 million in maintenance payments and $147.9 million in letters of credit from our lessees.
We believe thatwe have sufficient liquidity to meet our contractual obligations over the next twelve months and as of July 1, 2021, total liquidity of $2.88 billion includes $1.38 billion of undrawn credit facilities, $1.02 billion of unrestricted cash, on hand,$103 million of contracted asset sales and $375 million of projected operating cash flows through June 30, 2022. In addition, we believe payments received from lessees and other funds generated from operations, unsecured bond offerings, secured borrowings for aircraft, borrowings under our revolving credit facilities and other borrowings and proceeds from future aircraft sales will be sufficient to satisfy our liquidity and capital resource needs over the next twelve months. Our liquidity and capital resource needs include payments due under our aircraft purchase obligations, required principal and interest payments under our long-term debt facilities, expected capital expenditures, lessee maintenance payment reimbursements and lease incentive payments over the next twelve months.

Operating Activities:
The COVID-19 pandemic has severely impacted the demand for air travel over the past fifteen months, which has negatively impacted our customers’ financial performance. The impact of COVID-19, together with lease concessions given to many of our airline customers in the form of lease rental deferrals, has resulted in slower cash collections during the three months ended May 31, 2021 and 2020.
Cash flow provided by operations was $393.5$70.0 million and $367.4 million for the ninethree months ended September 30, 2017 and 2016, respectively. May 31, 2021 as compared to cash flow used in operations of $44.5 million for the three months ended May 31, 2020. The net increase in cash flow provided by operations of approximately $26.0$114.5 million for the nine months endedSeptember 30, 2017 versus the same period in 2016 was primarily a result of:
a $30.7$98.7 million decrease in accounts receivable and other assets, primarily due to deferred lease rentals;
a $32.1 million increase in cash receivedas the three months ended May 31, 2020, included higher banking and legal costs resulting from maintenance revenue;the Merger; and

a $9.3 million decrease in cash paid for taxes.recognized into revenue, primarily due to lease terminations.
These inflows were offset by a $10.9$39.9 million decrease in cash due to lower lease rental revenue resulting from working capitalearly lease terminations and the recognition of lease rental revenue for certain customers using a $14.8 million increase in cash paid for interest.basis of accounting rather than an accrual method.
Investing Activities:
Cash flow provided by investing activities was $173.8$4.5 million and $17.8 million for the ninethree months ended September 30, 2017 as compared to cash flow used in investing activities of $395.5 million for the nine months endedSeptember 30, 2016.May 31, 2021 and 2020, respectively. The net increasedecrease in cash flow provided by investing activities of $569.4$13.3 million for the nine months endedSeptember 30, 2017 versus the same period in 2016 was primarily a result of:
of a $280.1$42.4 million net decreaseincrease in the acquisition and improvement of flight equipment and net investments in finance and sales-type leases;equipment.
These outflows were offset by a $276.2$17.2 million increase in aircraft purchase deposits and progress payments, net of returned deposits and an $11.5 million increase in aircraft proceeds from the sale of flight equipment; and
a $12.7 million decrease in unconsolidated equity method investments.equipment.
Financing Activities:
Cash flow used in financing activities was $392.9$9.5 million for the ninethree months ended September 30, 2017 May 31, 2021 as compared to cash flow provided by financing activities of $484.3$186.2 million for the ninethree months endedSeptember 30, 2016. May 31, 2020. The net increase in cash flow used in financing activitiesdecrease of $877.2$195.8 million for the nine months ended September 30, 2017 versus the same period in 2016 was primarily a result of:
of a $499.4$253.3 million decrease in proceeds from secured and unsecured financings;financings, net of repayments.
These outflows were offset by a $363.3$38.1 million increase in securitization and term debt financing repayments; and

Capital Expenditures
From time to time, we make capital expenditures to maintain or improve our aircraft. These expenditures include the cost of major overhauls necessary to place an aircraft in service and modifications made at the request of lessees. For the ninethree months ended September 30, 2017May 31, 2021 and 2016,2020, we incurred a total of $24.4$6.5 million and $27.0$7.1 million, respectively, of capital expenditures (including lease incentives) related to the acquisition and improvement of aircraft.
As of September 30, 2017,May 31, 2021, the weighted average age by net book value of our aircraft was approximately 8.710.8 years. In general, the costs of operating an aircraft, including maintenance expenditures, increase with the age of the aircraft. Our lease agreements call for the lessee to be primarily responsible for maintaining the aircraft. We may incur additional maintenance and modification costs in the future in the event we are required to remarket an aircraft, such as lessee default, or a lessee fails to meet its maintenance obligations under the lease agreement. These maintenance reserves are paid by the lessee to provide for future maintenance events. Provided a lessee performs scheduled maintenance of the aircraft, we are required to reimburse the lessee for scheduled maintenance payments. In certain cases, we are also required to make lessor contributions, in excess of amounts a lessee may have paid, towards the costs of maintenance events performed by or on behalf of the lessee.
Actual maintenance payments to us by lessees in the future may be less than projected as a result of a number ofseveral factors, including defaults by the lessees. Maintenance reserves may not cover the entire amount of actual maintenance expenses

incurred and, where these expenses are not otherwise covered by the lessees, there can be no assurance that our operational cash flow and maintenance reserves will be sufficient to fund maintenance requirements, particularly as our aircraft age. See Item 1A. “Risk Factors - Risks Related to Our Business - Risks related to our leases - If lessees are unable to fund their maintenance obligations on our aircraft, we may incur increased costs at the conclusion of the applicable lease” in our 2016 Annual Report on Form 10-K.10-K for the year ended February 28, 2021.

Off-Balance Sheet Arrangements
We entered into twoa joint venture arrangementsarrangement in order to help expand our base of new business opportunities. None of theseThis joint ventures qualifiesventure does not qualify for consolidated accounting treatment. The assets and liabilities of these entitiesthis entity are not included in our Consolidated Balance Sheets and we record our net investment under the equity method of accounting. See Note 5 - “Unconsolidated Equity Method Investments” in the Notes to Unaudited Consolidated Financial Statements above.
We hold a 30% equity interest in our Lancaster joint venture and a 25% equity interest in our IBJ Air joint venture. At September 30, 2017,venture with Mizuho Leasing and as of May 31, 2021, the net book value of our two joint ventures’ thirteenits nine aircraft was approximately $661$308.6 million.
Foreign Currency Risk and Foreign Operations
At September 30, 2017,May 31, 2021, all of our leases are payable to us in U.S. dollars. However, we incur Euro and Singapore dollar-denominated expenses in connection with our subsidiaries in Ireland and Singapore. For the ninethree months endedSeptember 30, 2017, May 31, 2021, expenses, such as payroll and office costs, denominated in currencies other than the U.S. dollar aggregated approximately $14.2$4.5 million in U.S. dollar equivalents and represented approximately 26%28.9% of total selling, general and administrative expenses. Our international operations are a significant component of our business strategy and permit us to more effectively source new aircraft, service the aircraft we own and maintain contact with our lessees. Therefore, our international operations and our exposure to foreign currency risk will likely increase over time. Although we have not yet entered into foreign currency hedges because our exposure to date has not been significant, if our foreign currency exposure increases, we may enter into hedging transactions in the future to mitigate this risk. For the ninethree months ended September 30, 2017 May 31, 2021 and 2016,2020, we incurred insignificant net gains and losses on foreign currency transactions.
Hedging

Management’s Use of EBITDA and Adjusted EBITDA
We define EBITDA as income (loss) from continuing operations before income taxes, interest expense, and depreciation and amortization. We use EBITDA to assess our consolidated financial and operating performance, and we believe this non-U.S. GAAP measure is helpful in identifying trends in our performance.
This measure provides an assessment of controllable expenses and affords management the ability to make decisions which are expected to facilitate meeting current financial goals, as well as achieving optimal financial performance. It provides an indicator for management to determine if adjustments to current spending decisions are needed.
EBITDA provides us with a measure of operating performance because it assists us in comparing our operating performance on a consistent basis as it removes the impact of our capital structure (primarily interest charges on our outstanding debt) and asset base (primarily depreciation and amortization) from our operating results. Accordingly, this metric measures our financial performance based on operational factors that management can impact in the short-term, namely the cost structure, or expenses, of the organization. EBITDA is one of the metrics used by senior management and the Board of Directors to review the consolidated financial performance of our business.
We define Adjusted EBITDA as EBITDA (as defined above) further adjusted to give effect to adjustments required in calculating covenant ratios and compliance as that term is defined in the indenture governing our senior unsecured notes. Adjusted EBITDA is a material component of these covenants.

Management’s Use of Adjusted Net Income (“ANI”)
Management believes that ANI, when viewed in conjunction with the Company’s results under U.S. GAAP and the below reconciliation, provides useful information about operating and period-over-period performance and additional information that is useful for evaluating the underlying operating performance of our business without regard to periodic reporting elements related to interest rate derivative accounting, changes related to refinancing activity and non-cash share-based payment expense.

Limitations of EBITDA and Adjusted EBITDA and ANI
An investor or potential investor may find EBITDA and Adjusted EBITDA and ANI important measures in evaluating our performance, results of operations and financial position. We use these non-U.S. GAAP measures to supplement our U.S. GAAP results in order to provide a more complete understanding of the factors and trends affecting our business.
EBITDA and Adjusted EBITDA and ANI have limitations as analytical tools and should not be viewed in isolation or as substitutes for U.S. GAAP measures of earnings (loss). Material limitations in making the adjustments to our earnings (loss) to calculate EBITDA and Adjusted EBITDA, and ANI, and using these non-U.S. GAAP measures as compared to U.S. GAAP net income (loss), income (loss) from continuing operations and cash flows provided by or used in operations, include:
depreciation and amortization, though not directly affecting our current cash position, represent the wear and tear and/or reduction in value of our aircraft, which affects the aircraft’s availability for use and may be indicative of future needs for capital expenditures;
the cash portion of income tax (benefit) provision generally represents charges (gains), which may significantly affect our financial results;
elements of our interest rate derivative accounting may be used to evaluate the effectiveness of our hedging policy; and
hedge loss amortization charges; and
adjustments required in calculating covenant ratios and compliance as that term is defined in the indenture governing our senior unsecured notes.

notes which may not be comparable to similarly titled measures used by other companies.
EBITDA and Adjusted EBITDA and ANI are not alternatives to net income (loss), income (loss) from operations or cash flows provided by or used in operations as calculated and presented in accordance with U.S. GAAP. You should not rely on these non-U.S. GAAP measures as a substitute for any such U.S. GAAP financial measure. We strongly urge you to review the reconciliations to U.S. GAAP net income (loss), along with our consolidated financial statements included elsewhere in this report. We also strongly urge you to not rely on any single financial measure to evaluate our business. In addition, because EBITDA and Adjusted EBITDA and ANI are not measures of financial performance under U.S. GAAP and are susceptible to varying calculations, EBITDA and Adjusted EBITDA and ANI as presented in this report, may differ from and may not be comparable to similarly titled measures used by other companies.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest rate risk is the exposure to loss resulting from changes in the level of interest rates and the spread between different interest rates. These risks are highly sensitive to many factors, including U.S. monetary and tax policies, U.S. and international economic factors and other factors beyond our control. We are exposed to changes in the level of interest rates and to changes in the relationship or spread between interest rates. Our primary interest rate exposures relate to our lease agreements and floating rate debt obligations and interest rate derivatives. Rent payments under our aircraft lease agreements typically do not vary during the term of the lease according to changes in interest rates. However, our borrowing agreements generally require payments based on a variable interest rate index, such as LIBOR. Therefore, to the extent our borrowing costs are not fixed, increases in interest rates may reduce our net income by increasing the cost of our debt without any corresponding increase in rents or cash flow from our securities. If LIBOR is no longer available or in certain other circumstances as described in the borrowing agreements, the applicable borrowing agreements provide a mechanism for determining an alternative rate of interest. There is no assurance that any such alternative, successor or replacement reference rate will be similar to, or produce the same value or economic equivalence of, LIBOR.
Changes in interest rates may also impact our net book value as our interest rate derivatives are periodically marked-to-market through shareholders’ equity. Generally, we are exposed to loss on our fixed pay interest rate derivatives to the extent interest rates decrease below their contractual fixed rate.
The relationship between spreads on derivative instruments may vary from time to time, resulting in a net aggregate book value increase or decrease. Changes in the general level of interest rates can also affect our ability to acquire new investments and our ability to realize gains from the settlement of such assets.
Sensitivity Analysis
The following discussion about the potential effects of changes in interest rates is based on a sensitivity analysis, which models the effects of hypothetical interest rate shifts on our financial condition and results of operations. Although we believe a sensitivity analysis provides the most meaningful analysis permitted by the rules and regulations of the SEC, it is constrained by several factors, including the necessity to conduct the analysis based on a single point in time and by the inability to include the extraordinarily complex market reactions that normally would arise from the market shifts modeled. Although the following results of a sensitivity analysis for changes in interest rates may have some limited use as a benchmark, they should not be viewed as a forecast. This forward-looking disclosure also is selective in nature and addresses only the potential interest expense impacts on our financial instruments and, in particular, does not address the mark-to-market impact on our interest rate derivatives. It also does not include a variety of other potential factors that could affect our business as a result of changes in interest rates.
A hypothetical 100-basis point increase/decrease in interest rates on our leases subject to variable interestrental rates would increase/decrease the minimum contracted rentals onin our portfolio as of September 30, 2017May 31, 2021 by $2.3$0.5 million and $2.3$0.1 million, respectively, over the next twelve months. As of September 30, 2017,May 31, 2021, a hypothetical 100-basis point increase/decrease in interest rates on our variable interest rate on our borrowings would result in an interest expense increase/decrease of $3.9 million and $5.3$0.9 million, respectively, net of amounts received from our interest rate derivatives, over the next twelve months. In September 2016, we purchasedWe have an interest rate cap for $2.3 million to hedge approximately 70%a portion of our floating rate interest exposure. The interest rate capexposure which is set at 2% and has a current notional balance of $405.0$220.0 million and reduces over time to $215.0 million. The cap matures in September 2021.
