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 is acquiring, leasing, managing and selling commercial jet aircraft.

Aircastle is a holding company that conducts its business through subsidiaries. Aircastle directly or indirectly owns all of the outstanding common shares of its subsidiaries. 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, we believe that the disclosures are adequate to make 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, 2018 .

Effective January 1, 2019, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 842, Leases (“ASC 842”) which, together with all subsequent amendments, replaced the existing guidance in ASC 840, Leases (“ASC 840”). The accounting for leases by lessors remained largely unchanged from the concepts that existed in ASC 840. The FASB decided that lessors would be precluded from recognizing selling profit and revenue at lease commencement for any sales-type or direct financing 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 revenue recognition standard, which evaluates whether a sale has occurred from the customer’s perspective.

As a result of the Company’s adoption of ASC 842, we have recognized right-of-use assets and lease liabilities on our Consolidated Balance Sheet as of March 31, 2019, for our office leases classified as operating leases under ASC 842, existing at, or entered into after, January 1, 2019. We adopted the standard using the required “modified retrospective” approach and the available practical expedients. The standard did not have a material impact on our consolidated financial statements and related disclosures.

As part of the Company’s adoption of ASC 842, we classified collections on direct financing and sales-type leases within operating activities on our Consolidated Statement of Cash Flows for the three months ended March 31, 2019 . This had previously been included within investing activities. The presentation for the three months ended March 31, 2018 , has also been reclassified to conform to the current period presentation:



	Three Months Ended March 31, 2018
Net cash and restricted cash provided by operating activities as previously reported	$	142,412
Collections on direct financing and sales-type leases	6,493
Net cash and restricted cash provided by operating activities	$	148,905

The Company’s management has reviewed and evaluated all events or transactions for potential recognition and/or disclosure since the balance sheet date of March 31, 2019 , through the date on which the consolidated financial statements included in this Form 10-Q were issued.

March 31, 2019

Principles of Consolidation

The consolidated financial statements include the accounts of Aircastle and all of its subsidiaries. Aircastle consolidates four Variable Interest Entities (“VIEs”) of which Aircastle is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation.

We consolidate VIEs in which we have determined that we are the primary beneficiary. We use judgment when deciding: (a) whether an entity is subject to consolidation as a VIE; (b) who the variable interest holders are; (c) the potential expected losses and residual returns of the variable interest holders; and (d) which variable interest holder is the primary beneficiary. When determining which enterprise is the primary beneficiary, we consider: (1) the entity’s purpose and design; (2) which variable interest holder has the power 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.

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 initial lease, assuming no renewals. Operating lease rentals that adjust based on a London Interbank Offered Rate (“LIBOR”) index are recognized on a straight-line basis over the lease term using the prevailing rate at lease commencement. Changes to rate-based lease rentals are recognized in the statement of income in the period of change.

Flight Equipment Held for Lease and Depreciation

Estimated residual values are generally determined to be approximately 15% of the manufacturer’s estimated realized price for passenger aircraft when new and 5% to 10% for freighter aircraft when new. Management may make exceptions to this policy on a case-by-case basis when, in its judgment, the residual value calculated pursuant to this policy does not appear to reflect current expectations of value or when events or changes in circumstances, or indicators, suggest that the carrying amount or net book value of an asset may not be recoverable.

In June 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments and related updates. The standard affects entities holding financial assets and net investments 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 replaces today’s incurred loss model with an expected loss model that requires entities to consider a broader range of information to estimate expected credit losses over the lifetime of the asset. Under the new standard, an allowance for credit losses is recorded which represents amounts not expected to be collected. 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 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement . The standard modifies certain disclosure requirements for fair value measurements as part of its disclosure framework project. The standard is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of determining the impact the standard will have on our related disclosures.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40), Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. The standard requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use-software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. The standard is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. We are in the process of determining the impact the standard will have on our consolidated financial statements and related disclosures.

In October 2018, the FASB issued ASU No. 2018-17, Consolidation (Topic 810), Targeted Improvements to Related Party Guidance for Variable Interest Entities . The standard changes how all entities evaluate decision-making fees under the variable interest entity guidance. The standard is applied retrospectively with a cumulative-effect adjustment to retained earnings at the beginning of the earliest period presented. The standard is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of determining the impact the standard will have 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 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 March 31, 2019 and December 31, 2018 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.

Total	$	172,739	$	167,853	$	4,886	$	—

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 and are therefore classified as Level 1 within our fair value hierarchy. Our derivative assets included in Level 2 consist of United States dollar-denominated interest rate caps, 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 months ended March 31, 2019 and the year ended December 31, 2018 , we had no 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 assets may not be recoverable. Assets subject to these measurements include our investments 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 and the Company determines that the decline is other than temporary. 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 an income approach which uses Level 3 inputs, which include the Company’s assumptions and appraisal data as to future cash proceeds from leasing and selling aircraft.

On April 10, 2019, the Company early terminated the leases for seven Boeing 737NG aircraft on lease to Jet Airways (India) Limited due to lessee default. As a result of these lease terminations, the Company will recognize net maintenance revenue of $17,554 and impairment charges of $7,404 in the second quarter of 2019.

Financial Instruments

Our financial instruments, other than cash, consist principally of cash equivalents, restricted cash and cash equivalents, accounts receivable, accounts payable, amounts borrowed under financings and interest rate derivatives. 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.

The carrying amounts and fair values of our financial instruments at March 31, 2019 and December 31, 2018 were as follows:



	March 31, 2019				December 31, 2018

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 our net investment in direct financing and sales-type leases. 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 related aircraft, with a net book value as of March 31, 2019 of $390,233 , 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 March 31, 2019 is $175,963 .

Unsecured Debt Financings:

Unsecured Term Loan

On February 27, 2019, we entered into an aggregate $215,000 floating rate loan commitment with Development Bank of Japan Inc. and certain other banks (the “Unsecured Term Loan”). This loan is split into two tranches: Tranche A for $60,000 with a three -year term; and Tranche B for $155,000 with a five -year term. The loan contains a $750,000 minimum net worth covenant, along with other customary provisions similar to our revolving credit facilities. This loan was funded in March 2019.

The new Unsecured Term Loan replaces our existing term loan of $120,000 that matured on April 28, 2019.

Revolving Credit Facility

On December 27, 2018, we entered into a $250,000 three -year, unsecured revolving credit facility with a group of banks based in Asia. This new facility can be increased to a maximum of $350,000 . On January 25, 2019, we increased the facility by $30,000 to $280,000 . The facility bears interest at a rate of LIBOR plus 1.50% and matures in December

Aircastle Limited and Subsidiaries

(Dollars in thousands, except per share amounts)

March 31, 2019

2021. The facility contains provisions similar to our existing credit facilities, including a $750,000 minimum net worth covenant.

As a condition to this new facility, on January 9, 2019, we terminated our existing $135,000 revolving credit facility with a group of banks based in Asia.

At March 31, 2019 , we had $375,000 outstanding under our revolving credit facilities and had $705,000 available for borrowing.

As of March 31, 2019 , we were in compliance with all applicable covenants in our financings.

Note 8. Shareholders' Equity and Share-Based Payment

During the three months ended March 31, 2019 , the Company granted 268,331 restricted common shares and granted 287,342 performance share units (“PSUs”). These awards were made under the Aircastle Limited Amended and Restated 2014 Omnibus Incentive Plan. We repurchased 156,876 shares totaling $2,915 from our employees and directors to settle tax obligations related to share vesting.

During the three months ended March 31, 2019 , the Company incurred share-based compensation expense of $1,257 related to restricted common shares and $1,469 related to PSUs.

As of March 31, 2019 , there was $8,690 of unrecognized compensation cost related to unvested restricted common share-based payments and $10,643 of unrecognized compensation cost related to unvested PSU share-based payments that are expected to be recognized over a weighted-average remaining period of 1.94 years .

During the three months ended March 31, 2019 , we repurchased 496,920 common shares at an aggregate cost of $8,733 , including commissions. At March 31, 2019 , the remaining dollar value of common shares that may be purchased under the repurchase program is $76,019 .

Note 10. Earnings per Share

We include all common shares granted under our incentive compensation plan which remain unvested (“restricted common shares”) and contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid (“participating securities”), in the number of shares outstanding in our basic earnings per share calculations using the two-class method. All of our restricted common shares are currently participating securities. Our PSUs are contingently issuable shares which are included in our diluted earnings per share calculations which do not include voting or dividend rights.

Under the two-class method, earnings per common share is computed by dividing the sum of distributed earnings allocated to common shareholders and undistributed earnings allocated to common shareholders by the weighted-average

(1)	For the three months ended March 31, 2019 and 2018 , distributed and undistributed earnings to restricted shares were 0.58% and 0.55% , respectively, of net income. The amount of restricted share forfeitures for all periods presented are immaterial to the allocation of distributed and undistributed earnings.


(2)	For all periods presented, dilutive shares represented contingently issuable shares.

Note 11. Income Taxes

Income taxes have been provided based on the tax laws and rates in countries in which our operations are conducted and income is earned. 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 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 and the United States.

Our aircraft-owning subsidiaries that are recognized as corporations for U.S. tax purposes are primarily non-U.S. corporations. These subsidiaries generally earn income from sources outside the United States and typically are not subject to U.S. federal, state or local income taxes. The aircraft owning subsidiaries resident in Ireland, Mauritius and the U.S. are subject to tax in those respective jurisdictions.

We have a U.S. based subsidiary which provides management services to our 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.

The consolidated income tax expense for the three months ended March 31, 2019 and 2018 was determined based upon estimates of the Company’s consolidated effective income tax rates for the years ending December 31, 2019 and 2018, respectively.

The Company’s effective tax rate (“ETR”) for the three months ended March 31, 2019 was 8.1% , compared to (1.5)% , for the three months ended March 31, 2018 . The first quarter of 2018 included a $2,779 tax benefit related to the Singapore rate reduction from 10% to 8% , which was treated as a discrete item. Excluding this tax benefit, the ETR would have been 3.6% for the three months ended March 31, 2018 . Movements in the ETR are generally caused by changes in the proportion of the Company’s pre-tax earnings in taxable and non-tax jurisdictions. During the three months ended March 31, 2019, we reported a significant decrease in Bermuda income primarily relating to Avianca Brazil.

Differences between statutory income tax rates and our effective income tax rates applied to pre-tax income from continuing operations consisted of the following:

OVERVIEW

Aircastle acquires, leases, and sells commercial jet aircraft to airlines throughout the world. As of March 31, 2019 , we owned and managed on behalf of our joint ventures 274 aircraft leased to 86 lessees located in 47 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. In many cases we are, however, obligated to pay a specified portion of maintenance or modification costs. As of March 31, 2019 , the net book value (including flight equipment held for lease and net investment in direct financing and sales-type leases, or “net book value”) was $7.64 billion compared to $7.40 billion at December 31, 2018 . Our revenues and net income for the three months ended March 31, 2019 were $213.9 million and $34.8 million , respectively.

Growth in commercial air traffic is broadly correlated with world economic activity. In recent years, commercial air traffic growth has expanded at a rate 1.5 to 2 times that of global GDP growth. The expansion of air travel has driven a rise in the world aircraft fleet. There are currently approximately 22,000 commercial mainline passenger and freighter aircraft in operation worldwide. This fleet is expected to continue expanding at a three to four percent average annual rate over the next twenty years. Aircraft leasing companies own approximately 44% of the world’s commercial jet aircraft.

2019 continues to show strong growth in air traffic. According to the International Air Transport Association, during the first two months of 2019 , global passenger traffic increased 5.9% compared to the same period in 2018 . Demand for air travel varies by region. Emerging market economies have generally been experiencing greater increases in air traffic, driven by rising levels of per capita income leading to an increased propensity to fly. Mature markets, such as North America and Western Europe, have been growing more slowly in tandem with their economies. Air traffic growth is also being driven by the proliferation of low cost carriers, which have stimulated demand through lower prices. The outlook for airlines operating in areas with political instability or weakening economies 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.

Notwithstanding the sector’s long-term growth, the aviation market is subject to economic variability due to changes in macroeconomic variables, such as interest rates, 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 there is demand.

Fuel prices and interest rates have had a substantial effect on our industry. After dropping to a low of $36 per barrel in December 2015, the price of fuel has risen to an average of $60 per barrel during 2019. While still below historic highs, higher fuel prices have impacted airline profitability. The prolonged low interest rate environment and the strong overall performance of the aircraft financing sector attracted significant new capital, increasing competition for new investments and putting pressure on margins and returns. After the Federal Reserve increased interest rates in the U.S. during 2018, guidance has recently shifted back to a neutral position.

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 investment opportunity. Strong U.S. debt capital market conditions benefit borrowers by permitting access to financing at historic lows. Commercial bank debt also continues to play a critical role for aircraft finance. Export credit agency availability, however, has been curtailed due to political issues, both in the U.S. and in Europe. While financial market conditions remain attractive, geopolitical issues may increase capital costs and limit availability going forward.

We believe capital market developments should generate attractive additional 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. During 2018, we achieved investment grade credit ratings from Moody’s, Standard & Poor’s and Fitch. We believe being an investment grade issuer will reduce our borrowing costs and enable more reliable access to debt capital throughout the business cycle.

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 the nature and volume of assets we buy will vary over time with market conditions. We plan to grow our business and profits over the long-term while maintaining a conservative, flexible capital structure. 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 less reliant on orders for new aircraft from aircraft manufacturers as a source of new investments than many of our competitors.

Our business strategy entails the following elements:

•

Pursuing a disciplined and differentiated investment strategy. In our view, the relative values of different aircraft change over time. We continually 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 our team’s experience with a wide range of asset types and the financing flexibility offered through unsecured debt provides us with a competitive advantage. We view orders from equipment manufacturers to be part of our investment opportunity set, but choose to keep our long term capital commitments limited.

•

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. 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 94 different sellers.


•	Selling assets when attractive opportunities arise. We sell assets with the aim of realizing profits and reinvesting proceeds. We also use asset sales for portfolio management purposes, such as reducing lessee specific concentrations and lowering residual value exposures to certain aircraft types. Since our formation, we have sold aircraft to 67 buyers.

•

Maintaining efficient access to capital from a wide set of sources and leveraging our recent 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 prices are high. To implement this approach, we believe it is important to maintain access to a wide variety of financing sources. During 2018, we achieved our objective of improving 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 our improved credit rating will not only reduce our borrowing costs, but also facilitate more reliable access to both unsecured and secured 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 is one of the largest Japanese trading companies. Marubeni has enabled greater access to Japanese-based financing and helped source and develop our joint venture with the leasing arm of the Industrial Bank of Japan, Limited.

•

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 February 8, 2019 , our Board of Directors declared a regular quarterly dividend of $0.30 per common share, or an aggregate of $22.5 million for the three months ended March 31, 2019 , which was paid on March 15, 2019 to holders of record on February 28, 2019 . 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 2018 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, interest recognized from direct financing and sales-type leases and gains from aircraft sales.

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 or near 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.

On April 10, 2019, the Company early terminated the leases for seven Boeing 737NG aircraft on lease to Jet Airways (India) Limited equipped with CFM56-7B engines. The Company has repossessed all seven aircraft and is in the process of transitioning them to a new lessee. As a result of the lease terminations of these seven aircraft, the Company will recognize net maintenance revenue of $17.6 million and impairment charges of $7.4 million in the second quarter of 2019. For more information regarding risks associated with our lessees see Item 1A. “Risk Factors - Risks Related to Our Lessees” in our 2018 Annual Report on Form 10-K.

2019 Lease Expirations and Lease Placements

At March 31, 2019 , the Company had twelve aircraft off-lease and eighteen aircraft with scheduled lease expirations in 2019. As of April 30, 2019 , we have three aircraft which account for 1.5% of our net book value at March 31, 2019, still to be placed or sold.

2020-2023 Lease Expirations and Lease Placements

Taking into account lease and sale commitments, we currently have the following number of aircraft with lease expirations scheduled in the period 2020-2023, representing the percentage of our net book value of flight equipment (including flight equipment held for lease and net investment in direct financing and sales-type leases) at March 31, 2019 , specified below:


•	2020: 22 aircraft, representing 6%;


•	2021: 27 aircraft, representing 8%;


•	2022: 30 aircraft, representing 9%; and


•	2023: 32 aircraft, representing 10%.

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 scheduled transitions and 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 the United States and Ireland.

Acquisitions and Sales

During the first three months of 2019 , we acquired fourteen aircraft for $444.7 million . As of April 30, 2019 , we have acquired two additional aircraft. At March 31, 2019 , we had commitments to acquire 37 additional aircraft for $1.36 billion , including the acquisition of 25 new E-Jet E2 aircraft from Embraer, with delivery beginning in the third quarter of 2020. Of this amount, approximately $426.9 million represents commitments for the remainder of 2019 . As of April 30, 2019 , we have commitments to acquire 35 aircraft for $1.28 billion .

During the first three months of 2019 , we sold four aircraft for net proceeds of $56.3 million , and recognized net gains on sales of $12.0 million, comprised of $8.3 million from the sale of these aircraft and $3.7 million resulting from the transition of two aircraft from operating to net investment in direct financing and sales-type leases. As of April 30, 2019 , we have sold no additional aircraft.

The following table sets forth certain information with respect to the aircraft owned by us as of March 31, 2019 :

Finance

We believe that cash on hand, payments received from lessees and other funds generated from operations, 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. 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.

See “Liquidity and Capital Resources” below.

Revenues

Total revenues increased by $11.2 million for the three months ended March 31, 2019 as compared to the three months ended March 31, 2018 .

Lease rental revenue . The increase in lease rental revenue of $3.8 million for the three months ended March 31, 2019 as compared to the same period in 2018 was primarily the result of increases in revenue of $38.6 million, reflecting the partial period impact of thirteen aircraft purchased in 2019, and the full period impact due to the acquisition of 37 aircraft since January 1, 2018. This increase was offset by:


•	a $25.2 million decrease due to lease extensions, amendments, transitions and other changes ($15.9 million of which is attributable to Avianca Brazil and Jet Airways), and


•	a $9.6 million decrease due to the sale of eleven aircraft since January1, 2018.

Direct financing and sales-type lease revenue. For the three months ended March 31, 2019 , $8.4 million of interest income from direct financing and sales-type leases was recognized as compared to $9.4 million for the same period in 2018 due to the sale of two aircraft and the termination of one direct financing lease, partially offset by the acquisition of one aircraft and the reclassification of two aircraft from operating to direct financing leases since January 1, 2018.

Amortization of lease premiums, discounts and lease incentives consisted of the following:



	Three Months Ended March 31,
	2019			2018
	(Dollars in thousands)
Amortization of lease incentives	$	(3,100	)	$	(2,682	)
Amortization of lease premiums	(4,037		)	(2,439		)
Amortization of lease discounts	1,426			1,993

Amortization of lease premiums, discounts and incentives	$	(5,711	)	$	(3,128	)

Lease premiums represent the present value of the amount above current market lease rates for acquired aircraft with attached leases. The increase in amortization of lease premiums of $1.6 million for the three months ended March 31, 2019 , as compared to the same period in 2018 , resulted primarily from a net increase in amortization resulting from net aircraft acquisitions.

Maintenance revenue. For the three months ended March 31, 2019 , we recorded $16.4 million of maintenance revenue, primarily due to the transition of one narrow-body aircraft and two wide-body aircraft, in addition to cash maintenance revenue received for ten narrow-body aircraft. For the same period in 2018 , we recorded $12.0 million of maintenance revenue primarily due to the transition of one freighter aircraft.

Gain on sale of flight equipment increased by $6.2 million to $12.0 million for the three months ended March 31, 2019 , as compared to gains of $5.8 million for the same period in 2018 . During the three months ended March 31, 2019 , we sold four aircraft with higher gains on sale, as compared to the sale of four aircraft during the same period in 2018 . We also recognized gains totaling $3.7 million resulting from the transition of two aircraft from operating to net investment in direct financing and sales-type leases.

Operating expenses

Total operating expenses increased by $22.7 million for the three months ended March 31, 2019 as compared to the three months ended March 31, 2018 .

Depreciation expense increased by $9.7 million for the three months ended March 31, 2019 as compared to the same period in 2018 . The increase is primarily the result of higher depreciation of $14.1 million due to the effect of 50 aircraft acquired since January 1, 2018. These increases were partially offset by a decrease of $5.2 million in depreciation due to thirteen aircraft sold.

Interest, net consisted of the following:



	Three Months Ended March 31,
	2019			2018
	(Dollars in thousands)
Interest on borrowings and other liabilities	$	60,279		$	53,978
Amortization of deferred losses related to interest rate derivatives	184			301
Amortization of deferred financing fees and debt discount	3,364			3,532
Interest expense	63,827			57,811
Less: Interest income	(364		)	(703		)

Interest, net	$	63,463		$	57,108

Interest, net increased by $6.4 million as compared to the three months ended March 31, 2018 . This increase was the result of higher weighted average debt outstanding.

Selling, general and administrative expenses for the three months ended March 31, 2019 were flat as compared to the same period in 2018 .

Maintenance and other costs were $7.4 million for the three months ended March 31, 2019 , an increase of $6.4 million compared to the same period in 2018 . T he net increase is primarily attributable to higher than projected lessor contributions towards the cost of maintenance events for aircraft acquired with attached leases of $3.4 million, scheduled transitions, and lease terminations for the three months ended March 31, 2019 versus the same period in 2018.

Other income (expense)

Total other income (expense) decreased by $5.2 million for the three months ended March 31, 2019 as compared to the three months ended March 31, 2018 . The net decrease in other income was primarily attributable to mark-to-market adjustments on our interest rate caps.

Income tax provision (benefit)

Our income tax provision (benefit) for the three months ended March 31, 2019 and 2018 was $3.1 million and $(0.8) 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 and the United States. The increase in our income tax provision of approximately $3.9 million for the three months ended March 31, 2019 , as compared to the same period in 2018 , was primarily attributable to changes in operating income subject to tax in Ireland, the United States and other jurisdictions. Pre-tax earnings for the three months ended March 31, 2018 included the recording of the discrete item of a $2.8 million tax benefit related to the Singapore rate reduction from 10% to 8%.

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.

Aircraft Monitoring List

At March 31, 2019 , no aircraft were on our monitoring list. We monitor our fleet for aircraft that are more susceptible to failing our recoverability assessments within one year due to their sensitivity to changes in contractual cash flows, future cash flow estimates and aircraft residual or scrap values.

RECENTLY UNADOPTED ACCOUNTING PRONOUNCEMENTS

See Note 1 - “Summary of Significant Accounting Policies – Recent Accounting Pronouncements” in the Notes to Unaudited Consolidated Financial Statements above.

LIQUIDITY AND CAPITAL RESOURCES

Our business is very capital intensive, requiring significant investments in order to expand our fleet and to maintain and improve our existing portfolio. Our operations generate a significant amount of cash, primarily from lease rentals and maintenance collections. We have also met our liquidity and capital resource needs by utilizing several sources over time, including:


•	unsecured indebtedness, including our current unsecured revolving credit facilities, term loan and senior notes;


•	various forms of borrowing secured by our aircraft, including bank term facilities, limited recourse securitization financings, and ECA-backed financings for new aircraft acquisitions;


•	asset sales; and


•	sales of common 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 three months of 2019 , we met our liquidity and capital resource needs with $106.4 million of cash flow from operations, $215.0 million of gross proceeds from the Unsecured Term Loan and $56.3 million of cash from aircraft sales.

As of March 31, 2019 , the weighted-average maturity of our secured and unsecured debt financings was 3.2 years and we were in compliance with all applicable covenants.

We believe that cash on hand, payments received from lessees and other funds generated from operations, 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.

Cash Flows



	Three Months Ended March 31,
	2019			2018
	(Dollars in thousands)
Net cash flow provided by operating activities	$	106,360		$	148,905
Net cash flow used in investing activities	(286,246		)	(50,612		)
Net cash flow provided by (used in) financing activities	120,241			(99,811		)

Operating Activities:

Cash flow provided by operations was $106.4 million and $148.9 million for the three months ended March 31, 2019 and 2018 , respectively. The decrease in cash flow provided by operations of $42.5 million for the three months ended March 31, 2019 versus the same period in 2018 was primarily a result of a $17.7 million increase in cash paid for interest, a $10.1 million decrease in cash received from maintenance revenue, an $8.2 million decrease in cash from working capital and a $6.4 million increase in cash paid for maintenance.

Investing Activities:

Cash flow used in investing activities was $286.2 million and $50.6 million for the three months ended March 31, 2019 and 2018 , respectively. The increase in cash flow used in investing activities of $235.6 million for the three months ended March 31, 2019 versus the same period in 2018 was primarily a result of a $257.1 million increase in the acquisition and improvement of flight equipment and net investments in direct financing and sales-type leases.

These outflows were primarily offset by a $12.4 million increase in aircraft proceeds from the sale of flight equipment.

Financing Activities:

Cash flow provided by financing activities was $120.2 million for the three months ended March 31, 2019 as compared to cash flow used in financing activities of $99.8 million for the three months ended March 31, 2018 . The net increase in cash flow provided by financing activities of $220.1 million for the three months ended March 31, 2019 versus the same period in 2018 was primarily a result of a $215.0 million increase in proceeds from secured and unsecured financings and a $25.6 million decrease in securitization and term debt financing repayments.

These inflows were offset by a $16.2 million decrease in maintenance payments and security deposits received, net of returns.

Debt Obligations

For complete information on our debt obligations, please refer to Note 7 - “Secured and Unsecured Debt Financings” in the Notes to Unaudited Consolidated Financial Statements above.

Contractual Obligations

Our contractual obligations consist of principal and interest payments on debt, other aircraft acquisition agreements and rent payments related to our office leases. Total contractual obligations increased to $7.09 billion at March 31, 2019 from $6.95 billion at December 31, 2018 , due primarily to an increase in aircraft purchase obligations, partially offset by debt amortization.

The following table presents our actual contractual obligations and their payment due dates as of March 31, 2019 :

(2)	Represents contractual payment obligations for our office leases in Stamford, Connecticut; Dublin, Ireland and Singapore.


(3)	At March 31, 2019 , we had commitments to acquire 37 aircraft for $1.36 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 April 30, 2019 , we have commitments to acquire 35 aircraft for $1.28 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 three months ended March 31, 2019 and 2018 , we incurred a total of $7.9 million and $1.6 million, respectively, of capital expenditures (including lease incentives) related to the improvement of aircraft.

As of March 31, 2019 , the weighted average age by net book value of our aircraft was approximately 9.4 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 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 of 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 2018 Annual Report on Form 10-K.

Off-Balance Sheet Arrangements

We entered into two joint venture arrangements in order to help expand our base of new business opportunities. None of these joint ventures qualifies for consolidated accounting treatment. The assets and liabilities of these entities 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 March 31, 2019 , the net book value of our two joint ventures’ fifteen aircraft was $685.6 million . We recognized our share of the undistributed loss in our joint venture with Teachers’ of $0.7 million during the quarter ended March 31, 2019 , the loss of which is attributable to a fair value impairment recorded by the joint venture as a result of a confirmed letter of intent to sell its aircraft to a third party buyer.

Foreign Currency Risk and Foreign Operations

At March 31, 2019 , 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 three months ended March 31, 2019 , expenses, such as payroll and office costs, denominated in currencies other than the U.S. dollar aggregated approximately $4.4 million in U.S. dollar equivalents and represented approximately 24% 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 three months ended March 31, 2019 and 2018 , we incurred insignificant net gains and losses on foreign currency transactions.

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.

The table below shows the reconciliation of net income to EBITDA and Adjusted EBITDA for the three months ended March 31, 2019 and 2018 :

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.

The table below shows the reconciliation of net income to ANI for the three months ended March 31, 2019 and 2018 :

Limitations of EBITDA, Adjusted EBITDA and ANI

An investor or potential investor may find EBITDA, 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, 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, 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;


•	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.

EBITDA, 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, Adjusted EBITDA and ANI are not measures of financial performance under U.S. GAAP and are susceptible to varying calculations, EBITDA, 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 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.

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 our variable interest rates would increase/decrease the minimum contracted rentals on our portfolio as of March 31, 2019 by $4.3 million and $4.3 million , respectively, over the next twelve months. As of March 31, 2019 , a hypothetical 100-basis point increase/decrease in our variable interest rate on our borrowings would result in an interest expense increase/decrease of $7.5 million and $8.3 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 to hedge a portion of our floating rate interest exposure. The interest rate cap is set at 2% and has a current notional balance of $365.0 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 March 31, 2019 . 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 March 31, 2019 .

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 March 31, 2019 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
