Note 1. Summary of Significant Accounting Policies
Organization and Basis of Presentation
Aircastle Limited (“Aircastle,” the “Company,” “we,” “us” or “our”) is a Bermuda exempted company that was incorporated on October 29, 2004, under the provisions of Section 14 of the Companies Act of 1981 of Bermuda. Aircastle’s business isconsists of acquiring, leasing, managing and selling commercial jet aircraft.
The Company is controlled by affiliates of Marubeni Corporation (“Marubeni”) and Mizuho Leasing Company, Limited (“Mizuho Leasing” and, together with Marubeni, our “Shareholders”).
Aircastle is a holding company thatand conducts its business through subsidiaries. Aircastlesubsidiaries that are wholly owned, either directly or indirectly, owns allby Aircastle.
Basis of the outstanding common sharesPresentation and Principles of its subsidiaries. Consolidation
The consolidated financial statements presented are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The Company manages, analyzes and reports on its business and results of operations on the basis of one operating segment: leasing, financing, selling and managing commercial flight equipment. Our chief executive officer is the chief operating decision maker.
The accompanying consolidated financial statements are unaudited and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial reporting and, in our opinion, reflect all adjustments, including normal recurring items, which are necessary to present fairly the results for interim periods. 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.
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 since the balance sheet date of September 30, 2017 through the date on which the consolidated financial statements included in this Form 10-Q were issued.
Principles of ConsolidationFebruary 28, 2023.
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 VIEsmanage and analyze our business and report on our results of operations based on one operating segment: leasing, financing, selling and managing commercial flight equipment. Our Chief Executive Officer is the chief operating decision maker.
The Company’s management has reviewed and evaluated all events or transactions for potential recognition and/or disclosure subsequent to the balance sheet date of August 31, 2023, through the date on which the consolidated financial statements included in this Form 10-Q were issued.
Risk 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 early 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.refinance existing debt facilities.

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,In March 2020, the FASBFinancial Accounting Standards Board (“FASB”) issued Accounting Standards CodificationStandard Update (“ASC”ASU”) 8422020-04, Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASC 842”848”), “Leases,” which replaced the existing guidance in. ASC 840, Leases. The accounting848 provides temporary optional expedients and exceptions to certain U.S. GAAP contract modification requirements for leasescontracts affected by lessors basically remained unchangedreference rate reform as entities transition away 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 assetLondon Interbank Offered Rate (“LIBOR”) 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 afteralternative reference rates. In 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 2016,2022, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement2022-06 to defer the sunset date of Credit Losses on Financial InstrumentsASC 848 from December 31, 2022, to December 31, 2024, after which entities will no longer be permitted to apply the optional expedients in ASC 848.
The ICE Benchmark Administration Limited, LIBOR’s administrator, has ceased publishing all LIBOR settings, including the Overnight, 1-month, 3-month, 6-month, and 12-month USD LIBOR U.S. dollar settings. Effective March 1, 2023, we adopted ASC 848 and commenced the transition of our LIBOR-based contracts to the Secured Overnight Financing Rate (“SOFR” or “Term SOFR”). The standard affects entities holding financial assets and net investment inAs of August 31, 2023, we had no aircraft leases that are not accountedor debt financings 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 fromwhich 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 earlyassociated lease rental revenue or interest expense used LIBOR as the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are in the processapplicable reference rate. The adoption 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 willASC 848 did not have a material impact on our consolidated financial statements and related disclosures.statements.
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

conditions or classification of the award changes. In addition, when applicable, disclosure is required to indicate that compensation expense has not changed. The update should be applied using a prospective 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.
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 the 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, 2017August 31, 2023 and December 31, 2016February 28, 2023 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 our 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 (Level 1). Our investments in debt and equity securities consist of notes and shares received as a result of claims settlements from various airline customers that had entered into bankruptcy proceedings or similar-type restructurings.

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 investmentsaircraft and investment 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. venture.
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 (Level 2), which includes third party appraisal data, and an income approach (Level 3), which uses Level 3 inputs, which includeincludes the Company’s assumptions and appraisal data as to future cash proceeds from leasing and selling aircraft.

During the third quarter of 2017, we sold one production freighter and one converted freighter aircraft. We expect to sell one production freighter aircraft in the first quarter of 2018.

Management believes that the net book value of each aircraftdecline 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 our estimates or assumptions change, we may revise our cash flow assumptions and record future impairment charges. While we believe that the estimates and related assumptions used in the annual recoverability assessment are appropriate, actual results could differ from those estimates.other-than-temporary.

Annual Recoverability Assessment
We plan to perform our annual recoverability assessment of all our aircraft during the third quarter of 2023.
Additional customer and aircraft specific recoverability assessments are also performed whenever indicators suggest the carrying amount of an asset may not be recoverable. Indicators may include, but are not limited to, a significant lease restructuring or early lease termination, a significant change in an 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. We have focused and will continue to focus on aircraft with near-term lease expirations, customers that have entered judicial insolvency proceedings and any additional customers that may become subject to similar-type proceedings, and certain other customers or aircraft variants that are more susceptible to value deterioration.
The recoverability assessment is a comparison of the carrying value of an aircraft to its estimated undiscounted future cash flows. We develop 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 revenue earned from flight equipment heldand maintenance payments, residual values, economic conditions, technology, airline demand for lease wasa particular aircraft type and other factors, such as follows:

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 of $278.5 million at August 31, 2023.

OVERVIEW
Aircastle acquires, leases, and sells commercial jet aircraft to airlines throughout the world. As of September 30, 2017, we owned and managed on behalf of our joint ventures 205 aircraft leased to 71 lessees located in 38 countries. Our aircraft are managed by an experienced team based in the United States, Ireland and Singapore. Our aircraft are 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. During the six months ended August 31, 2023, we purchased 8 aircraft and sold 10 aircraft and other flight equipment. As of September 30, 2017,August 31, 2023, we owned and managed on behalf of our joint venture 248 aircraft leased to 74 airline customers located in 43 countries. As of August 31, 2023, the net book value (including flight equipment heldNet Book Value of our fleet was $6.8 billion. The weighted average age of our fleet was 9.7 years, and the weighted average remaining lease term was 5.2 years. As of August 31, 2023, we had commitments to acquire 12 aircraft for lease$402.4 million, which included estimated amounts for pre-delivery deposits, contractual price escalations and net investment in finance and sales-type leases, or "net book value") was $5.98 billion compared to $6.51 billion at December 31, 2016. other adjustments.
Our total revenues, and net income and Adjusted EBITDA were $386.4 million, $28.3 million and $343.1 million, respectively, for the three and ninesix months ended September 30, 2017 were $191.4August 31, 2023. Cash flow provided by operating activities was $186.4 million for the six months ended August 31, 2023. Our leadership team and $57.4 million,other senior professionals have extensive industry and $619.2 million and $92.8 million, respectively.financial experience, including managing through downturns in the aviation industry.
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 half to two times that of global GDP growth. TheThis expansion of air travel has driven a risegrowth in the world aircraft fleet. Therefleet; and there are currently approximately 20,00026,000 commercial mainline passenger and freighter aircraft in operation worldwide. Thisthe world fleet is expected to continue expanding at three to four percent average annual rate over the next twenty years.today. Aircraft leasing companies own approximately 41%49% of the world’s commercial jet aircraft. Under normal circumstances, we would expect the global fleet to continue expanding at a 2 to 3% average annual rate.
Notwithstanding the sector’sAs a leading secondary market investor, we believe that our long-standing business strategy of maintaining conservative leverage and limiting long-term growth, the aviation markets have been,financial commitments has enabled us to manage through recent crises. Our portfolio, primarily comprised of a balanced mix of new technology and are expectedmid-life, narrow-body aircraft, should remain attractive assets for our airline customers 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.  Accordingrespond to the International Air Transport Association, during the first eight monthsgrowing demand 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 likely 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 increase over time, and as a result, we expect demand for modern aircraft will 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. Both debt and equity markets have improved globally over the past several years with the recovery from the global financial crisis. Strong U.S. debt capital market conditions benefited borrowers by permitting access to financing at historic lows while higher fees have driven down ECA demand. Recently, ECA availability has been curtailed, both in the U.S. and in Europe, due to political issues and an investigation into possible irregularities, respectively. Commercial bank debt continues to play a critical role for aircraft finance, although 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 placed to capitalize given our access 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.travel.
We believe that we have sufficient liquidity to meet our business approach is differentiated from thosecontractual obligations over the next twelve months and as 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 targetsOctober 6, 2023, total liquidity of $2.8 billion includes $1.9 billion of undrawn facilities, $0.5 billion of projected adjusted operating cash flow and growth rates will vary with market conditions. We prefer to have capital resources available to capture investment opportunities that arise in the contextcontracted asset sales, $0.3 billion of changing market circumstances. As such, we limit large, long-term capitalequity commitments and are therefore much less reliant on orders for new aircraft from aircraft manufacturers as a source$0.1 billion of new investments.unrestricted cash through October 1, 2024.
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 part of our investment opportunity set, but choose to limit long term capital commitments unless we believe there is an adequate return premium to compensate 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, we have acquired aircraft from 86 different sellers.
Selling assets when attractive opportunities arise. We sell assets with the aim of realizing profits and reinvesting proceeds when a sale generates the greatest expected cash flow or when more accretive investments are available. We also use asset sales for portfolio management purposes, such as reducing lessee specific concentrations and lowering residual value exposures to certain aircraft types.
Maintaining efficient access to capital from a wide set 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 low 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-based financing and helped source and develop our joint venture with IBJL (“IBJ Air”). IBJ Air is targeted at newer narrow-body aircraft leased to premier airlines, providing Aircastle with increased access to this market sector and to these customers. Our joint venture with Teachers’ (“Lancaster”) provides us with an opportunity to pursue larger transactions, manage portfolio concentrations and improve our return on deployed capital.
Capturing the value of our efficient operating platform and strong operating track record. We believe our team’s capabilities in the 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 lease 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.
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.

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 ninesix months of 2017,ended August 31, 2023, we acquired 288 aircraft for $635.1$341.7 million. As of OctoberAugust 31, 2017, we have acquired 37 aircraft for approximately $760 million. At September 30, 2017,2023, we had commitments to acquire 64 additional12 aircraft for $1.80 billion, including$402.4 million, with delivery through the acquisitionsecond quarter of 25 new E-Jet E2 aircraft from Embraer,2025, which are scheduled to deliver in 2019 to 2021.includes estimated amounts for pre-delivery deposits, contractual price escalations and other adjustments. As of October 31, 2017,6, 2023, we have acquired 2 additional aircraft and have commitments to acquire 5512 aircraft for $1.68 billion.$400.2 million.
During the first ninesix months of 2017,ended August 31, 2023, we sold 2910 aircraft and other flight equipment for $765.0net proceeds of $126.0 million which resulted inand recognized a net gain on sale of $35.9 million.

Finance
We believe thatoperate in a capital-intensive industry and have a demonstrated track record of raising substantial amounts of capital from debt and equity investors. Since our inception in late 2004, we have raised $2.3 billion in equity capital from private and public investors. We also raised $20.7 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, and other funds generated from operations,unsecured bond offerings, borrowings secured borrowings forby our aircraft, borrowingsdraws under 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, theThe amortization of lease incentives generally increasesincreased $1.6 million, primarily due to the transition of aircraft to new lessees.

Depreciation expense increased $4.2 million primarily attributable to an increase of $9.6 million related unused lease incentive liability will reduce the amortizationto 29 aircraft acquired since June 1, 2022, partially offset by a decrease of lease incentives. The$5.5 million related to 20 aircraft sold since June 1, 2022.
Interest, net increased $6.4 million due to a higher average cost of borrowing and higher weighted average debt outstanding of $247.7 million.
Selling, general and administrative expenses increased $1.5 million, primarily due to an increase in amortizationpersonnel costs and ongoing Russian litigation expenses.
Impairment of aircraft. We recorded an impairment charge of $1.1 million during the three months ended August 31, 2023.

The Company recognized $6.1 million of maintenance revenue for this 1 aircraft.
Maintenance and other costs increased $3.6 million, primarily attributable to higher aircraft insurance premiums and higher costs due to the timing of transition of aircraft to new lessees.Higher transition costs are largely related to aircraft for which the previous lease was terminated early, and the aircraft was repossessed from the prior operator.
Other income
Total other income was $3.4 million and $2.1 million for the three months ended September 30, 2017, as compared to the same period in 2016, wasAugust 31, 2023 and 2022, respectively, and primarily attributable to the reversalconsists of lease incentives associated with one freighter aircraft due to changes in estimate and the reclassification of one aircraft from an operating lease to a finance lease.

Revenues
Total revenues increased $37.3 million, attributable to:
Lease rental revenue increased $6.4 million, primarily attributable to changes in operating income subject to tax in Ireland, Singapore, the United States and other jurisdictions.
Allan increase 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.

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 is amortized over the life of the related lease. As we enter into new leases, theThe 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 increase in amortization of lease incentives ofincreased $3.1 million, fordue to the ninetransition of aircraft to new lessees.
Maintenance revenue. For the six months ended September 30, 2017 as compared to the same period in 2016 was primarily attributable to the reversal of lease incentives associated with two freighter aircraft due to changes in estimate and the reclassification of one aircraft from an operating lease to a finance lease.

Annual Recoverability Assessment
We completedplan to perform our annual recoverability assessment of all our aircraft induring the secondthird quarter this year. Weof 2023.
Additional customer and aircraft specific recoverability assessments are also performed aircraft-specific analyses where there were changeswhenever indicators suggest the carrying amount of an asset may not be recoverable. Indicators may include, but are not limited to, a significant lease restructuring or early lease termination, a significant change in circumstances, such as approachingan 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. We have focused and will continue to focus on aircraft with near-term lease expirations. Other than the transactional impairments discussed above, noexpirations, customers that have entered judicial insolvency proceedings and any additional customers that may become subject to similar-type proceedings, and certain other impairments were recorded as a result of our annual recoverability assessment.customers or aircraft variants that are more susceptible to value deterioration.
The recoverability assessment is a comparison of the carrying value of eachan aircraft to its estimated undiscounted expected future cash flows. We develop the assumptions used in the recoverability assessment, including those relating toanalysis based on current and future expectations of the global demand for eacha particular aircraft type based on management’sand historical experience in the aircraft leasing market and aviation industry, as well as information received from third-party industry sources. Estimates ofThe factors considered in estimating the undiscounted cash flows for each aircraft type are impacted by changes in contractedfuture periods due to changes in projected lease rental and future expected lease rates,maintenance payments, residual values, expected scrap values, economic conditions, technology, airline demand for a particular aircraft type and other factors.
Management believes thatfactors, such as the net book valuelocation 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, ifaccessibility to records and technical documentation.
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.
Aircraft Monitoring List

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, term financings and 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
salesissuance of common and preference 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 ninesix months of 2017,ended August 31, 2023, we met our liquidity and capital resource needs with $393.5$186.4 million of cash flowflows from operations $500.0and $126.0 million in grossof proceeds from the issuancesale of our Senior Notes due 2024aircraft and $765.0 million of cash from aircraft sales.other flight equipment.
As of September 30, 2017,August 31, 2023, the weighted-average maturity of our secured and unsecured debt financings was 3.92.7 years, and we arewere in compliance with all applicable covenants.
We believe that we have sufficient liquidity to meet our contractual obligations over the next twelve months and as of October 6, 2023, total liquidity of $2.8 billion includes $1.9 billion of undrawn facilities, $0.5 billion of projected adjusted operating cash on hand,flow and contracted asset sales, $0.3 billion of equity commitments and $0.1 billion of unrestricted cash through October 1, 2024. In addition, we believe payments received from lessees and other funds generated from operations, unsecured bond offerings, borrowings secured borrowings forby our 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.payments.

Excluding the impact of these letters of credit, cash provided by operating activities decreased slightly, primarily a result of:
a $30.7 million increase in cash received from maintenance revenue;
a $12.0 million increase in cash from lease rentals, net of finance and sales-type leases; and
a $9.3 million decrease in cash paid for taxes.
These inflows were offset by a $10.9 million decrease in cash from working capital and a $14.8 million increase in cash paid for interest.due to higher interest costs on our debt financings.

(3)At September 30, 2017, we had commitments to acquire 64 aircraft for $1.80 billion, including 25 new E-Jet E2 aircraft from Embraer S.A. These amounts include estimates for pre-delivery deposits, contractual price escalation and other adjustments. As of October 31, 2017, we have commitments to acquire 55 aircraft for $1.68 billion.
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 ninesix months ended September 30, 2017August 31, 2023 and 2016,2022, we incurred a total of $24.4$44.3 million and $27.0$49.4 million, respectively, of capital expenditures, (includingincluding lease incentives)incentives, related to the acquisition and improvement of aircraft.
As of September 30, 2017,August 31, 2023, the weighted average age by net book valueNet Book Value of our aircraft was approximately 8.79.7 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 weMaintenance reserves are required to remarket an aircraft or a lessee fails to meet its maintenance obligations under the lease agreement. These maintenance reserves aregenerally 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
32


events performed by or on behalf of the lessee. We may incur additional maintenance and modification costs in the future in the event we are required to remarket an aircraft, such as in the event of a lessee default or a lessee fails to meet its maintenance obligations under the lease agreement.
Actual maintenance payments to us by lessees in the future may be less than projected as a result of several factors, such as in the event of a number of factors, including defaults by the lessees.lessee default. 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, 2023.
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 Sheetsconsolidated balance sheets, and we record our net investment under the equity method of accounting. See Note 5 - “Unconsolidated Equity Method Investments”7 in the Notes to Unaudited Consolidated Financial Statements above.Statements.
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 August 31, 2023, the net book value of our two joint ventures’ thirteenits 9 aircraft was approximately $661$278.5 million.
Foreign Currency Risk and Foreign Operations
At September 30, 2017, allAugust 31, 2023, more than 99% of our leases arewere 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 ninesix months endedSeptember 30, 2017, August 31, 2023, expenses, such as payrollpersonnel and office costs, denominated in currencies other than the U.S. dollar aggregated approximately $14.2totaled $10.8 million in U.S. dollar equivalents and represented approximately 26%27% 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 ninesix months ended September 30, 2017 August 31, 2023 and 2016,2022, 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 interest expense, 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.

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 provision (benefit) provision generally represents charges (gains), which may significantly affect our financial results; and
elements of our interest rate derivative accounting may be used to evaluate the effectiveness of our hedging policy;
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 not 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, floating ratefloating-rate debt obligations and interest rate derivatives.obligations. Rent payments under our aircraft lease agreements typically do not vary
34


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.SOFR or an alternative reference rate. 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.
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.instruments. 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 our variable interest rates would increase/decrease the minimum contracted rentals on our portfolio as of September 30, 2017 by $2.3 million and $2.3 million, respectively, over the next twelve months. As of September 30, 2017,August 31, 2023, a hypothetical 100-basis point increase/decrease in our variable interest rate on our borrowings would result in an interest expense increase/decrease of $3.9$4.2 million and $5.3$4.2 million, respectively, net of amounts received from our interest rate derivatives, over the next twelve months. In September 2016, we purchased an interest rate cap for $2.3 million to hedge approximately 70% of our floating rate interest exposure. The interest rate cap is set at 2% and has a current notional balance of $405.0 million and reduces over time to $215.0 million. The cap matures in September 2021.

ITEM 4. CONTROLS AND PROCEDURES
Management’s Evaluation of Disclosure Controls and Procedures
The term “disclosure controls and procedures” is defined in Exchange Act Rules 13a-15(e) and 15d-15(e). This term refers to the controls and procedures of a company that are designed to ensure that information required to be disclosed by

a company in the reports that it files under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the SEC and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) as appropriate, to allow timely decisions regarding required disclosure. An evaluation was performed under the supervision and with the participation of the Company’s management, including the CEO and CFO, of the effectiveness of the Company’s disclosure controls and procedures as of September 30, 2017.August 31, 2023. Based on that evaluation, the Company’s management, including the CEO and CFO, concluded that the Company’s disclosure controls and procedures were effective as of September 30, 2017.August 31, 2023.
Changes in Internal Control over Financial Reporting
There were no changes in the Company’s internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f), that occurred during the quarter ended September 30, 2017August 31, 2023, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
