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 investing in aviation assets, including leasing, managing and selling commercial jet aircraft to airlines throughout the world and investing in aircraft related debt investments.

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 (“US GAAP”). We operate in a single segment.

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 US 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, 2012.

The Company’s management has reviewed and evaluated all events or transactions for potential recognition and/or disclosure since the balance sheet date of June 30, 2013 through the date on which the consolidated financial statements included in this Form 10-Q were issued.

Principles of Consolidation

The consolidated financial statements include the accounts of Aircastle and all of its subsidiaries. Aircastle consolidates eight 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.

Effective January 1, 2013, the Company adopted Financial Accounting Standards Board (the "FASB") Accounting Standards Update ("ASU") 2013-02 (“ASU 2013-02”) Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This ASU requires that companies present reclassification adjustments for each component of accumulated other comprehensive income (“AOCI”) either on the face of the financial statements or in the notes, provided that all required information is presented in a single location. ASU 2013-02 is effective for interim and annual reporting periods beginning after December 15, 2012 and should be applied prospectively. The adoption of ASU 2013-02 did not have a material impact on the Company's consolidated financial statements.

Effective January 1, 2013, the Company adopted ASU 2011-11 (“ASU 2011-11”) Balance Sheet (Topic 210) Disclosures about Offsetting Assets and Liabilities. This ASU requires that companies disclose information to enable users of its financial statements to evaluate the effect or potential effect of netting arrangements on its financial position. ASU 2011-11 is effective for interim and annual reporting periods beginning on or after January 1, 2013 and should be applied retrospectively for all

periods presented on the balance sheet. The adoption of ASU 2011-11 did not have a material impact on the Company's consolidated financial statements.

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. Market risk reflects the change in the value of derivatives and financings due to changes in interest rate spreads or other market factors, including the value of collateral underlying derivatives and financings. Aviation industry risk is the risk of a downturn in the commercial aviation industry which could adversely impact a lessee’s ability to make payments, increase the risk of unscheduled lease terminations and depress lease rates and the value of the Company’s aircraft. Capital market risk is the risk that the Company is unable to obtain capital at reasonable rates to fund the growth of our business or to refinance existing debt facilities.

Use of Estimates

The preparation of financial statements in conformity with US 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.

Proposed Accounting Pronouncements

In May 2013, the FASB issued re-exposure draft, “Leases” (the “Lease Re-ED”), which would replace the existing guidance in the Accounting Standards Codification (“ASC”) 840 (“ASC 840”), Leases. The FASB decided that leases would be classified as either leases of property (Type B) or leases of assets other than property (Type A). Leases of property will continue to use operating lease accounting. Leases of other than property would use the receivable residual approach. Under the receivable residual approach, a lease receivable would be recognized for the lessor's right to receive lease payments, a portion of the carrying amount of the underlying asset would be allocated between the right of use granted to the lessee and the lessor's residual value and profit or loss would only be recognized at commencement if it is reasonably assured. The comment period for the Lease Re-ED ends September 13, 2013. We anticipate that the final standard may have an effective date no earlier than 2017. When and if the proposed guidance becomes effective, it may have a significant impact on the Company's consolidated financial statements. Although we believe the presentation of our financial statements, and those of our lessees could change, we do not believe the accounting pronouncement will change the fundamental economic reasons for which the airlines lease aircraft. Therefore, we do not believe it will have a material impact on our business.

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.

(Dollars in thousands, except per share amounts)

June 30, 2013

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 and liabilities as of December 31, 2012 and June 30, 2013 that we measured at fair value on a recurring basis by level within the fair value hierarchy. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to their fair value measurement. 

			Fair Value Measurements at December 31, 2012 Using Fair Value Hierarchy
	Fair Value as of December 31, 2012		Quoted Prices In Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Valuation Technique

			Fair Value Measurements at June 30, 2013 Using Fair Value Hierarchy

Liabilities:
Derivative liabilities	$	46,946	$	—	$	46,946	$	—	Income

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 interest rate derivatives included in Level 2 consist of United States dollar-denominated interest rate derivatives, and their fair values are determined by applying standard modeling techniques under the income approach to relevant market interest rates (cash rates, futures rates, swap rates) in effect at the period close to determine appropriate reset and discount rates and incorporates an assessment of the risk of non-performance by the interest rate derivative counterparty in valuing derivative assets and an evaluation of the Company’s credit risk in valuing derivative liabilities.

For the three and six months endedJune 30, 2012, we had no transfers into or out of Level 3; however we did terminate all Level 3 interest rate derivatives during the second quarter of 2012. For the three and six months endedJune 30, 2013, we had no transfers into or out of Level 3; however we did settle the debt investment during the first quarter of 2013.

We measure the fair value of certain assets and liabilities on a non-recurring basis, when US 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 aircraft. We record aircraft at fair value when we determine the carrying value may not be recoverable. Fair value measurements for aircraft impaired are based on an income approach that uses Level 3 inputs, which include our assumptions and appraisal data as to future cash proceeds from leasing and selling aircraft.

During the second quarter of 2012, we impaired two aircraft, one Boeing Model 757-200 aircraft that we sold for less than its net book value and one Boeing Model 767-300ER aircraft which was returned to us following its scheduled lease expiration and which failed its recoverability assessment. For these two aircraft, we recorded impairment charges of $10,111, and we recorded $2,447 of maintenance during the three and six months endedJune 30, 2012.

During the first quarter of 2013, we impaired two aircraft, one Airbus A319-100 aircraft and one Boeing 767-300ER aircraft, each of which was returned to us early by the respective lessee. The decision was made to sell these aircraft and the net book value of each was written down to the expected sale price. For these two aircraft, we recorded impairment charges totaling $6,199 and recorded maintenance revenue of $9,019 and other revenue of $876 during the six months endedJune 30, 2013.

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

Note 5. Variable Interest Entities

Aircastle consolidates eight 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 18 aircraft discussed below.

Securitizations

In connection with Securitization No. 1, two of our subsidiaries, ACS Aircraft Finance Ireland plc (“ACS Ireland”) and ACS Aircraft Finance Bermuda Limited (“ACS Bermuda”) issued Class A-1 notes, and each has fully and unconditionally guaranteed the other’s obligations under the notes. In connection with Securitization No. 2, two of our subsidiaries, ACS Aircraft Finance Ireland 2 Limited (“ACS Ireland 2”) and ACS 2007-1 Limited (“ACS Bermuda 2”) issued Class A-1 notes and each has fully and unconditionally guaranteed the other’s obligations under the notes. ACS Bermuda and ACS Bermuda 2 are collectively referred to as the “ACS Bermuda Group.”

Aircastle is the primary beneficiary of ACS Ireland and ACS Ireland 2 (collectively, the “ACS Ireland VIEs”), as we have both 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 Class E-1 Securities. Although Aircastle has not guaranteed the ACS Ireland VIEs debt, Aircastle wholly owns the ACS Bermuda Group which has fully and unconditionally guaranteed the ACS Ireland VIEs obligations. The activity that most significantly impacts the economic performance is the leasing of aircraft. Aircastle Advisor (Ireland) Limited (Aircastle’s wholly owned subsidiary) is the remarketing servicer and is responsible for the leasing of the aircraft. An Irish charitable trust owns 95% of the common shares of the ACS Ireland VIEs. The Irish charitable trust’s risk is limited to its annual dividend of $2 per VIE. At June 30, 2013, the assets of the two VIEs include 11 aircraft transferred into the VIEs at historical cost basis in connection with Securitization No. 1 and Securitization No. 2.

The combined assets of the ACS Ireland VIEs as of June 30, 2013 are $325,611. The combined liabilities of the ACS Ireland VIEs, net of $72,068 Class E-1 Securities held by the Company, which is eliminated in consolidation, as of June 30, 2013 are $278,978.

ECA Term Financings

Aircastle, through various subsidiaries, each of which is owned by a charitable trust (such entities, collectively the “Air Knight VIEs”), entered into eleven different twelve-year term loans, which are supported by guarantees from Compagnie Francaise d’ Assurance pour le Commerce Exterieur, (“COFACE”), the French government sponsored export credit agency (“ECA”). These loans provided for the financing for eleven new Airbus Model A330-200 aircraft. In June 2011, we repaid one of these loans from the proceeds of the sale of the related aircraft. In June 2013, we repaid two of these loans from the proceeds of the sale of the related aircraft. We sold an additional aircraft in June 2013, and we posted cash, which is reflected in restricted cash and cash equivalents on the consolidated balance sheet, as collateral for the related term loan until we pay-off the loan or substitute an aircraft. At June 30, 2013, Aircastle had eight outstanding term loans with guarantees from COFACE. We refer to these COFACE-supported financings as “ECA Term Financings.”

June 30, 2013

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 and deferred financing costs. The related aircraft, with a net book value as of June 30, 2013 were $585,646, are included in our flight equipment held for lease. The consolidated debt outstanding of the Air Knight VIEs as of June 30, 2013 is $515,034.

During the second quarter of 2013, we wrote off $3,825 of deferred financing fees which is reflected in interest expense on the consolidated statement of income. We sold an additional aircraft in June 2013, and we posted cash, which is reflected in restricted cash and cash equivalents on the consolidated balance sheet, as collateral for the related term loan until we pay-off the loan or substitute an aircraft.

Bank Financings

In May 2013, we assumed three floating rate loans and one fixed rate loan totaling $91,797 in connection with the acquisition of two Airbus Model A320-200 aircraft and two Boeing Model 737-800 aircraft. At June 30, 2013, these four loans had a weighted average interest rate of 1.65% and mature in 2018 and 2020.

We include these loan facilities in “Bank Financings”. Aircastle Limited has guaranteed the repayment of these Bank Financings.

As of June 30, 2013, we are in compliance with all applicable covenants in all of our financings.

Note 8.  Shareholders' Equity

During January 2013, we repurchased 679,292 common shares at an aggregate cost of $8,579 including commissions. The remaining dollar value of common shares that may be purchased under the repurchase program approved by the Company's Board of Directors on November 5, 2012 is $30,000.

Note 9. 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.

Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings allocated to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, distributed and undistributed earnings are allocated to both common shares and restricted common shares based on the total weighted average shares outstanding during the period as follows: 

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2013		2012		2013
Weighted-average shares:
Common shares outstanding	71,723,014		67,828,919		71,709,976		67,862,513
Restricted common shares	589,163		631,368		609,601		508,288
Total weighted-average shares	72,312,177		68,460,287		72,319,577		68,370,801
Percentage of weighted-average shares:
Common shares outstanding	99.19	%	99.08	%	99.16	%	99.26	%
Restricted common shares	0.81	%	0.92	%	0.84	%	0.74	%
Total	100.00	%	100.00	%	100.00	%	100.00	%

The amount of restricted share forfeitures for all periods present is immaterial to the allocation of distributed and undistributed earnings.

(b) For the three and six months endedJune 30, 2012 and 2013, we had no dilutive shares.

Note 10. Income Taxes

Income taxes have been provided for based upon 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 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.

The sources of income from continuing operations before income taxes for the three and six months endedJune 30, 2012 and 2013 were as follows: 

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2013		2012		2013
U.S. operations	$	357	$	791	$	681	$	1,196
Non-U.S. operations	17,313		35,795		52,520		62,038
Total	$	17,670	$	36,586	$	53,201	$	63,234

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

18

Aircastle Limited and Subsidiaries

Notes to Unaudited Consolidated Financial Statements

(Dollars in thousands, except per share amounts)

June 30, 2013

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. We also 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.

The consolidated income tax expense for the three and six months endedJune 30, 2012 and 2013 was determined based upon estimates of the Company's consolidated effective income tax rates for the years ending December 31, 2012 and 2013, respectively.

The Company's effective tax rate for the three and six months endedJune 30, 2012 was 7.6% and 8.0%, respectively, compared to 10.2% and 11.6%, respectively, for the three and six months endedJune 30, 2013. Movements in the effective tax rates are due primarily to changes in the proportion of the Company's earnings in taxable and non-tax jurisdictions. Because the geographic mix of pre-tax profits and losses in interim periods may not be reflective of full year results, this distorts our interim period effective tax rate.

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

	Three Months Ended June 30,						Six Months Ended June 30,
	2012			2013			2012			2013
Notional U.S. federal income tax expense (benefit) at the statutory rate	$	6,184		$	12,805		$	18,620		$	22,132
U.S. state and local income tax, net	25			52			49			86

Note 12. Commitments and Contingencies

At June 30, 2013, we had commitments to acquire three aircraft during the remainder of 2013 for $141,000.

Note 13. Derivatives

The objective of our hedging policy is to adopt a risk averse position with respect to changes in interest rates. Accordingly, we have entered into a number of interest rate derivatives to hedge the current and expected future interest rate payments on our variable rate debt. Interest rate derivatives are agreements in which a series of interest rate cash flows are exchanged with a third party over a prescribed period. The notional amount on an interest rate derivative is not exchanged. Our interest rate derivatives typically provide that we make fixed rate payments and receive floating rate payments to convert our floating rate borrowings to fixed rate obligations to better match the largely fixed rate cash flows from our investments in flight equipment.

We held the following interest rate derivatives as of June 30, 2013: 

	Derivative Liabilities
Hedged Item	Current Notional Amount		Effective Date	Maturity Date	Future Maximum Notional Amount		Floating Rate	Fixed Rate	Balance Sheet Location	Fair Value
Interest rate derivatives designated as cash flow hedges:
Securitization No. 1	$	227,698	Jun-06	Jun-16	$	227,698	1M LIBOR + 0.27%	5.78%	Fair value of derivative liabilities	$	29,191
Securitization No. 2	525,806		Jun-12	Jun-17	525,806		1M LIBOR	1.26% to 1.28%	Fair value of derivative liabilities	6,265
Total interest rate derivatives designated as cash flow hedges	$	753,504			$	753,504				$	35,456
Interest rate derivatives not designated as cash flow hedges:
Securitization No. 1	89,627		Jun-06	Jun-16	89,627		1M LIBOR + 0.27%	5.78%	Fair value of derivative liabilities	11,490
Total interest rate derivatives not designated as cash flow hedges	89,627				89,627					11,490
Total interest rate derivative liabilities	$	843,131			$	843,131				$	46,946

The weighted average interest pay rates of these derivatives at December 31, 2012 and June 30, 2013 were 2.91% and 2.97%, respectively.

For the six months endedJune 30, 2013, the amount of loss reclassified from accumulated other comprehensive income (“OCI”) into interest expense related to net interest settlements on active interest rate derivatives was $9,241. The amount of loss expected to be reclassified from OCI into interest expense over the next 12 months related to net interest settlements on active interest rate derivatives is $16,375.

June 30, 2013

Our interest rate derivatives involve counterparty credit risk. As of June 30, 2013, our interest rate derivatives are held with the following counterparties: JP Morgan Chase Bank NA, Citibank Canada NA, and Wells Fargo Bank NA. All of our counterparties or guarantors of these counterparties are considered investment grade (senior unsecured ratings of Baa2 or above) by Moody’s Investors Service. All are also considered investment grade (long-term foreign issuer ratings of A- or above) by Standard and Poor’s. We do not anticipate that any of these counterparties will fail to meet their obligations.

In addition to the derivative liability above, another component of the fair value of our interest rate derivatives is accrued interest. As of June 30, 2013, accrued interest payable included in accounts payable, accrued expenses, and other liabilities on our consolidated balance sheet was $802 related to interest rate derivatives designated as cash flow hedges and $185 related to interest rate derivatives not designated as cash flow hedges.

Following is the effect of interest rate derivatives on the statement of financial performance for the six months endedJune 30, 2013: 

Effective Portion				Ineffective Portion
Derivatives in ASC 815 Cash Flow Hedging Relationships	Amount of Gain or (Loss) Recognized in OCI on Derivative (a)	Location of Gain or (Loss) Reclassified from Accumulated OCI into Income	Amount of Gain or (Loss) Reclassified from Accumulated OCI into Income (b)	Location of Gain or (Loss) Recognized in Income on Derivative	Amount of Gain or (Loss) Recognized in Income on Derivative (c)
Interest rate derivatives	$2,959	Interest expense	$(26,979)	Interest expense	$(106)

(a) This represents the change in fair market value of our interest rate derivatives since year end, net of taxes, offset by the amount of actual cash paid related to the net settlements of the interest rate derivatives for the six months endedJune 30, 2013.

(b) This represents the amount of actual cash paid, net of taxes, related to the net settlements of the interest rate derivatives for the six months endedJune 30, 2013 plus any effective amortization of net deferred interest rate derivative losses.

(c) This represents both realized and unrealized ineffectiveness incurred during the six months endedJune 30, 2013.

Derivatives Not Designated as Hedging Instruments under ASC 815	Location of Gain or (Loss) Recognized in Income On Derivative	Amount of Gain or (Loss) Recognized in Income on Derivative
Interest rate derivatives	Other income (expense)	$	2,872

On an ongoing basis, terminated swap notionals are evaluated against debt forecasts. To the extent that interest payments are deemed remote to occur, deferred gains or losses are accelerated into interest expense as applicable.

For the six months endedJune 30, 2013, the amount of deferred net loss (including $2,027 of accelerated amortization driven by aircraft sales in 2013) reclassified from OCI into interest expense related to our terminated interest rate derivatives was $17,240. The amount of deferred net loss expected to be reclassified from OCI into interest expense over the next 12 months related to our terminated interest rate derivatives is $25,782 of which $16,899 relates to Term Financing No. 1 interest rate derivatives terminated in 2012, $1,373 relates to Term Financing No. 1 derivatives terminated in 2008, $6,166 relates to ECA Term Financings for New A330 Aircraft and $1,344 relates to other financings.

For the six months endedJune 30, 2013, the amount of effective deferred loss reclassified from OCI into interest expense related to our undesignated active interest rate derivative was $745. The amount of effective deferred loss expected to be reclassified from OCI into interest expense over the next 12 months related to our undesignated active interest rate derivative under our Securitization No. 1 is $1,678.

The following table summarizes amounts charged directly to the consolidated statement of income for the three and six months endedJune 30, 2012 and 2013, respectively, related to our interest rate derivatives:

OVERVIEW

We acquire, lease, and sell high-utility commercial jet aircraft. High-utility aircraft are generally modern, operationally efficient jets with many operators and long useful lives. As of June 30, 2013, our portfolio consisted of 158 aircraft leased to 67 lessees located in 36 countries. Our aircraft fleet is managed by an experienced team based in the United States, Ireland and Singapore. Typically, our aircraft are subject to net leases whereby the lessee is generally responsible for maintaining the aircraft and paying operational, maintenance and insurance costs, although in a majority of cases, we are obligated to pay a portion of specified maintenance or modification costs. From time to time, we also make investments in other aviation assets, including debt investments secured by commercial jet aircraft. Our revenues and net income for the three and six months endedJune 30, 2013 were $170.4 million and $32.9 million, and $346.6 million and $55.9 million, respectively.

The commercial jet aircraft market has grown 41% over the past 10 years and, in response, production levels for new aircraft by Boeing and Airbus have increased significantly during this time. For the first six months of 2013, air traffic data demonstrated improvement in both the passenger markets and the air cargo markets. According to the International Air Transport Association, global passenger traffic increased by 4.8% while air cargo traffic, measured in freight ton kilometers, increased 0.1% as compared to the same period in 2012. Increasing global GDP levels together with a proliferation of passenger air travel in emerging economies has driven the long-term growth in the commercial passenger jet aircraft market. On the other hand, the air cargo market has been sluggish since 2011, reflecting very low levels of world trade growth during this time.

The share of the world's commercial jet aircraft owned by leasing companies has expanded to 40% as compared to 25% ten years ago. The growing share of the world's aircraft fleet owned by aircraft lessors reflects more efficient and plentiful access to capital enjoyed by leasing companies in general, together with increased investment opportunities set resulting from higher new aircraft production levels. However, competition for aircraft investments, particularly for certain models such as newer, narrow-body aircraft, has increased over the past two years with the entrance of several new players as well as increased activity from many existing lessors.

The overall financing environment has improved over the past two to three years and aircraft owners have generally benefited from the low interest rate environment. Particularly strong conditions in the debt capital markets have provided select borrowers with access to such markets attractively priced, flexible financing that gives them a competitive advantage over airlines and lessors that lack similar access. Moreover, traditional asset-based financing for aircraft from banks remains limited, particularly for older aircraft.

We plan to grow our business and profits over the long-term by continuing to employ the following elements of our fundamental business strategy:

• Investing in additional commercial jet aircraft and other aviation assets when attractively priced opportunities and cost effective financing are available. We believe the large and growing aircraft market, together with ongoing fleet replacements, will provide significant acquisition opportunities. We regularly evaluate potential aircraft acquisitions and expect to continue our investment program through additional passenger and cargo aircraft purchases when attractively priced opportunities and cost effective financing are available.

• Maintaining efficient access to financing from multiple sources. We finance our aircraft acquisitions using various long-term debt structures obtained through several different markets to obtain cost effective financing. In this regard, we believe having corporate credit ratings from Standard & Poor’s and Moody’s enables us to access a broader pool of capital than many of our peers, enhancing our competitiveness and ability to source attractive investment opportunities. This, in turn, will allow us to grow our business and profits.

• Leveraging our efficient operating platform and strong operating track record. We believe our team's capabilities in the global aircraft leasing market place us in a favorable position to explore new income-generating activities and we intend to continue to focus our efforts in areas where we believe we have competitive advantages

25

and on transactions that offer attractive risk/return profiles after taking into consideration available financing options.

• Reinvesting a portion of the cash flows generated by our business in additional aviation assets and/or our own debt and equity securities. Aircraft have finite useful lives, but typically provide reliable cash flows. Our strategy is to reinvest a portion of our cash flows from operations and asset sales in our business to grow our asset base and earnings bases.

• Selling assets when attractive opportunities arise and for portfolio management purposes. We pursue asset sales as opportunities over the course of the business cycle with the aim of realizing profits and reinvesting proceeds where 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 and also to exit from an investment when a sale or part-out would provide the greatest expected cash flow for us.

We intend to pay quarterly dividends to our shareholders based on the company’s sustainable earnings levels; however, our ability to pay quarterly dividends will depend upon many factors, including those as previously disclosed in Aircastle’s 2012 Annual Report on Form 10-K. On February 18, 2013, our board of directors declared a regular quarterly dividend of $0.165 per common share, or an aggregate of $11.3 million, for the three months ended March 31, 2013, which was paid on March 15, 2013 to holders of record on March 4, 2013. On May 1, 2013, our board of directors declared a regular quarterly dividend of $0.165 per common share, or an aggregate of $11.3 million for the three months ended June 30, 2013, which was paid on June 14, 2013 to holders of record on May 31, 2013. These dividends may not be indicative of the amount of any future dividends.

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 leases.

Typically, our aircraft are subject to net operating leases whereby the lessee pays lease rentals and is generally responsible for maintaining the aircraft and paying operational, maintenance and insurance costs, although in a majority of cases we are obligated to pay a portion of specified maintenance or modification costs. 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 credit-worthiness of our lessees and the occurrence of delinquencies, 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

26

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.

When we acquire a leased aircraft, determining the fair value of the attached lease requires us to make assumptions regarding the current fair value of that lease. In doing so, we estimate a range of current lease rates of like aircraft in order to determine if the relevant lease is within a fair value range. If the lease rental is below or above the range of current lease rates, we present value the estimated amount below or above the fair value range over the remaining term of the lease. The resulting lease discount or premium is recorded as a liability or asset and is amortized into lease rental income over the remaining term of the lease.

2013 Lease Expirations and Lease Placements

We started the year with 19 aircraft having scheduled lease expirations in 2013 and we have leased, extended or sold 14 of these aircraft. The remaining 5 aircraft that we are marketing for lease or sale represented 1.8% of our total net book value of flight equipment (including flight equipment held for lease and net investment in finance leases) at June 30, 2013 and are expected to return to us off-lease in the fourth quarter of 2013. In the first half of 2013, we also leased or sold seven aircraft that were off-lease earlier in the year.

2014-2017 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 2014-2017 representing the percentage of our net book value of flight equipment (including flight equipment held for lease and net investment in finance leases) at June 30, 2013 specified below:

• 2014: 37 aircraft, representing 17%;

• 2015: 19 aircraft, representing 7%;

• 2016: 26 aircraft, representing 12%; and

• 2017: 27 aircraft, representing 21%.

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 have obtained an assurance from the Minister of Finance of Bermuda under the Exempted Undertakings Tax Protection Act 1966 that, in the event that 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 and the United States.

27

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. We also 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, those subsidiaries that are resident in Ireland are subject to Irish tax.

Acquisitions and Disposals

Thus far in 2013, we invested in ten aircraft for $454.8 million as follows:

• three aircraft for $294.8 million with ages of less than five years;

• four aircraft for $108.1 million between five and ten years in age;

• two aircraft for $40.1 million between ten and fifteen years in age; and

• one aircraft for $11.8 million with an age of over fifteen years.

As of June 30, 2013, we had commitments to acquire three aircraft for $141.0 million. Since June 30, 2013, we made additional commitments to acquire four aircraft for $371.2 million, for total commitments of $512.2 million.

During the first six months of 2013, the aggregate sales price for flight equipment sold was $253.9 million, which resulted in a net gain of $22.5 million. We repaid debt associated with this flight equipment in the amount of $154.7 million.

Finance

We intend to fund new investments through cash on hand, cash flows from operations and potentially through medium- to longer-term financings on a secured or unsecured basis. 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.

Revenues:

Total revenues decreased by 1.1%, or $1.8 million for the three months endedJune 30, 2013 as compared to the three months endedJune 30, 2012, primarily as a result of the following:

Lease rental revenue. The increase in lease rental revenue of $4.3 million for the three months endedJune 30, 2013 as compared to the same period in 2012 was primarily the result of:

• $22.9 million of revenue reflecting the full quarter impact of 16 aircraft purchased in 2012 and nine aircraft purchased in 2013; and

• $4.2 million due to lease extensions and transitions.

This increase was offset partially by a decrease in lease rental revenue of:

• $13.3 million from the effect of lease terminations and other changes; and

• $9.5 million due to aircraft sales and disposals.

Finance lease revenue: For the three months endedJune 30, 2013, $4.1 million of interest income from finance leases was recognized as compared to $1.0 million of interest income from finance leases recorded for the same period in 2012.

31

Amortization of net lease premiums, discounts and lease incentives.

	Three Months Ended June 30,
	2012			2013
	(Dollars in thousands)
Amortization of lease incentives	$	2,260		$	(6,829	)
Amortization of lease premiums	(672		)	(2,184		)
Amortization of lease discounts	456			304
Amortization of net lease premiums, discounts and lease incentives	$	2,044		$	(8,709	)

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, the amortization of lease incentives generally increases and, conversely, if a related lease terminates, the related unused lease incentive liability will reduce the amortization of lease incentives. The decrease in amortization of lease incentives of $9.1 million was primarily attributable to the reversal of $6.6 million of lease incentive amortization in the second quarter of 2012 related to two unscheduled lease transitions and one scheduled lease transition, resulting in lower amortization of lease incentives for the three months endedJune 30, 2012 as compared to the same period in 2013.

As more fully described above under “Revenues”, lease premiums represent the present value of the amount above current lease rates for acquired aircraft with attached leases. The increase in amortization of lease premiums of $1.5 million for the three months endedJune 30, 2013 as compared to the same period in 2012 primarily resulted from additional amortization on 11 aircraft purchased during 2012.

Maintenance revenue.

	Three Months Ended June 30,
	2012			2013
	Dollars (in  thousands)		Number of Leases	Dollars (in thousands)		Number of Leases
Unscheduled lease terminations	$	4,952	2	$	3,235	1
Scheduled lease terminations	8,583		3	9,950		4
Maintenance revenue	$	13,535	5	$	13,185	5

Unscheduled lease terminations. For the three months endedJune 30, 2012, we recorded maintenance revenue from unscheduled lease terminations of $5.0 million primarily associated with two aircraft returned in 2012. Comparatively, for the same period in 2013, we recorded maintenance revenue totaling $3.2 million from unscheduled lease terminations primarily associated with one aircraft returned in the second quarter of 2013 resulting from an early termination agreement with the lessee.

Scheduled lease terminations. For the three months endedJune 30, 2012, we recorded maintenance revenue from scheduled lease terminations of $8.6 million primarily associated with three scheduled lease terminations. Comparatively, for the same period in 2013, we recorded $10.0 million, primarily associated with maintenance revenue from four scheduled lease terminations.

Other revenue. For the three months endedJune 30, 2012, other revenue was $2.0 million comprised of $1.1 million of interest on our debt investments and $0.8 million recognized in additional fees paid by lessees in connection with early termination of two leases. For the three months endedJune 30, 2013, other revenue was $3.9 million which represents additional fees paid by one lessee in connection with the early termination of one lease.

Operating expenses:

Total operating expenses were flat for the three months endedJune 30, 2013 as compared to the three months endedJune 30, 2012, primarily as a result of the following:

32

Depreciation expense increased by 7.4%, or $5.0 million for the three months endedJune 30, 2013 as compared to the same period in 2012. The net increase is primarily the result of :

• a $7.0 million increase in depreciation for aircraft acquired; and

• a $4.0 million increase due to changes in asset lives and residual values.

This increase was partially offset by:

• a $5.5 million decrease in depreciation for aircraft disposals.

Interest, net consisted of the following:

	Three Months Ended June 30,
	2012			2013
	(Dollars in thousands)
Interest on borrowings, net settlements on interest rate derivatives, and other liabilities	$	48,798		$	50,823
Hedge ineffectiveness losses (gains)	1,885			(24		)
Amortization of interest rate derivatives related to deferred losses	8,866			9,711
Amortization of deferred financing fees and notes discount	4,975			6,346
Interest Expense	64,524			66,856
Less interest income	(173		)	(200		)
Less capitalized interest	(230		)	—
Interest, net	$	64,121		$	66,656

Interest, net increased by $2.5 million, or 4.0%, over the three months endedJune 30, 2012. The net increase is primarily a result of:

• a $2.0 million increase in interest expense on our borrowings driven by loan breakage fees in connection with the early repayment of two ECA loans of $3.0 million and the impact of higher weighted average debt outstanding ($3.51 billion for the three months endedJune 30, 2013 as compared to $3.19 billion for the three months endedJune 30, 2012), offset by lower interest due to lower weighted average interest rate, $6.0 million (5.5% for the three months endedJune 30, 2013 as compared to 6.2% for the three months endedJune 30, 2012);

• a $1.9 million decrease in hedge ineffectiveness resulting from changes in our debt forecast;

• a $1.4 million increase in amortization of deferred financing fees primarily due to the write-off of fees related to the early repayment of two ECA loans in June 2013; and

• a $0.8 million increase in amortization of deferred losses reflecting swap loss amortization related to the early repayment of two ECA Loans.

Selling, general and administrative expenses for the three months endedJune 30, 2013 increased slightly over the same period in 2012. Non-cash share based expense was $0.9 million and $1.1 million for the three months endedJune 30, 2012 and 2013, respectively.

Other income:

Total other income for the three months endedJune 30, 2013 was $24.3 million as compared to $3.6 million for the same period in 2012. The increase was due to a $18.5 million increase on gain on sale of flight equipment and a $0.9 million increase related to the mark to market value of an undesignated interest rate derivative.

Income tax provision

Our provision for income taxes for the three months endedJune 30, 2012 and 2013 was $1.3 million and $3.7 million, respectively. Income taxes have been provided based on the applicable tax laws and rates of those countries in which

33

operations are conducted and income is earned, primarily Ireland and the United States. The increase in our income tax provision of approximately $2.4 million for the three months endedJune 30, 2013 as compared to the same period in 2012 was primarily attributable to an increase in operating income subject to tax in the U.S. and Ireland.

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. We also 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, those subsidiaries that are resident in Ireland are subject to Irish tax.

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.

Other comprehensive income:

	Three Months Ended June 30,
	2012		2013
	(Dollars in thousands)
Net income	$	16,324	$	32,854
Net change in fair value of derivatives, net of tax expense of $139 and $193, respectively	5,799		8,127
Derivative loss reclassified into earnings	8,866		9,711
Total comprehensive income	$	30,989	$	50,692

Other comprehensive income was $50.7 million for the three months endedJune 30, 2013, an increase of $19.7 million from the $31.0 million of other comprehensive income for the three months endedJune 30, 2012. Other comprehensive income for the three months endedJune 30, 2013 primarily consisted of:

• $32.9 million of net income;

• $8.1 million gain from a change in fair value of interest rate derivatives, net of taxes which is due primarily to net settlements for the three months endedJune 30, 2013 partially offset by a slight loss due to a downward shift in the one-month LIBOR forward curve; and

• $9.7 million of amortization of deferred net losses reclassified into earnings related to terminated interest rate derivatives.

Other comprehensive income for the three months endedJune 30, 2012 primarily consisted of:

• $16.3 million of net income;

• a $5.8 million gain from a change in fair value of interest rate derivatives, net of taxes which is due primarily to net settlements for the three months endedJune 30, 2012, partially offset by a slight loss due to a downward shift in the one-month LIBOR forward curve; and

• $8.9 million of amortization of deferred net losses reclassified into earnings related to terminated interest rate derivatives.

Revenues:

Total revenues increased by 2.8%, or $9.5 million for the six months endedJune 30, 2013 as compared to the six months endedJune 30, 2012, primarily as a result of the following:

Lease rental revenue. The increase in lease rental revenue of $8.6 million for the six months endedJune 30, 2013 as compared to the same period in 2012 was primarily the result of:

• $44.9 million of revenue reflecting the full quarter impact of 17 aircraft purchased in 2012 and nine aircraft purchased in 2013; and

• $9.9 million due to lease extensions and transitions.

This increase was offset partially by a decrease in lease rental revenue of:

• $27.7 million from the effect of lease terminations and other changes; and

• $18.4 million due to aircraft sales and disposals.

Finance lease revenue: For the six months endedJune 30, 2013, $8.0 million of interest income from finance leases was recognized as compared to $1.0 million of interest income from finance leases recorded for the same period in 2012.

35

Amortization of net lease premiums, discounts and lease incentives.

	Six Months Ended June 30,
	2012			2013
	(Dollars in thousands)
Amortization of lease incentives	$	1,323		$	(12,186	)
Amortization of lease premiums	(1,914		)	(4,126		)
Amortization of lease discounts	1,037			522
Amortization of net lease premiums, discounts and lease incentives	$	446		$	(15,790	)

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, the amortization of lease incentives generally increases and, conversely, if a related lease terminates, the related unused lease incentive liability will reduce the amortization of lease incentives. The decrease in amortization of lease incentives of $13.5 million was primarily attributable to the reversal of $9.6 million of lease incentive amortization in the six months endedJune 30, 2012 related to three unscheduled lease transitions and two scheduled lease transitions, resulting in lower amortization of lease incentives for the six months endedJune 30, 2012 as compared to the same period in 2013.

As more fully described above under “Revenues”, lease premiums represent the present value of the amount above current lease rates for acquired aircraft with attached leases. The increase in amortization of lease premiums of $2.2 million for the six months endedJune 30, 2013 as compared to the same period in 2012 primarily resulted from additional amortization on 11 aircraft purchased during 2012.

Maintenance revenue.

	Six Months Ended June 30,
	2012			2013
	Dollars (in  thousands)		Number of Leases	Dollars (in thousands)		Number of Leases
Unscheduled lease terminations	$	14,811	4	$	19,995	7
Scheduled lease terminations	11,371		4	10,056		4
Maintenance revenue	$	26,182	8	$	30,051	11

Unscheduled lease terminations. For the six months endedJune 30, 2012, we recorded maintenance revenue from unscheduled lease terminations of $14.8 million primarily associated with four aircraft returned in 2012. Comparatively, for the same period in 2013, we recorded maintenance revenue totaling $20.0 million from unscheduled lease terminations primarily associated with seven aircraft returned in the first half of 2013 resulting from early termination agreements with those lessees.

Scheduled lease terminations. For the six months endedJune 30, 2012, we recorded maintenance revenue from scheduled lease terminations of $11.4 million associated with four scheduled lease terminations. Comparatively, for the same period in 2013, we recorded $10.1 million, associated with maintenance revenue from four scheduled lease terminations.

Other revenue. For the six months endedJune 30, 2012, other revenue was $3.6 million primarily comprised of $2.3 million of additional fees paid by lessees in connection with early termination of five leases and $1.2 million of interest on our debt investments. For the six months endedJune 30, 2013, other revenue was $9.8 million which was comprised of $1.6 million of interest on our debt investments and $8.0 million recognized in additional fees paid by six lessees in connection with the early termination of eight leases.

Operating expenses:

Total operating expenses increased by 7.8%, or $22.5 million for the six months endedJune 30, 2013 as compared to the six months endedJune 30, 2012, primarily as a result of the following:

36

Depreciation expense increased by 7.9%, or $10.4 million for the six months endedJune 30, 2013 as compared to the same period in 2012. The net increase is primarily the result of:

•a $14.1 million increase in depreciation for aircraft acquired; and

•a $5.7 million increase due to changes to asset lives and residual values.

This increase was offset by:

•a $9.1 million decrease in depreciation for aircraft disposals.

Interest, net consisted of the following:

	Six Months Ended June 30,
	2012			2013
	(Dollars in thousands)
Interest on borrowings, net settlements on interest rate derivatives, and other liabilities	$	93,767		$	99,414
Hedge ineffectiveness losses	366			104
Amortization of interest rate derivatives related to deferred losses	12,937			17,985
Amortization of deferred financing fees and notes discount	7,691			8,781
Interest Expense	114,761			126,284
Less interest income	(344		)	(476		)
Less capitalized interest	(1,315		)	—
Interest, net	$	113,102		$	125,808

Interest, net increased by $12.7 million, or 11.2%, over the six months endedJune 30, 2012. The net increase is primarily a result of:

• a $5.6 million increase in interest expense on our borrowings driven by driven by loan breakage fees of $3.0 million in connection with the early repayment of two ECA Loans and the impact of higher weighted average debt outstanding ($3.53 billion for the six months endedJune 30, 2013 as compared to $3.07 billion for the six months endedJune 30, 2012) of $13.9 million, partially offset by the effect of lower interest rates during the same period in the prior year of $11.2 million;

• a $5.0 million increase in amortization of deferred losses primarily due to deferred swap loss amortization related to the repayment of Term Financing No. 1 in April 2012 and the repayment of two ECA loans in June 2013;

• a $1.1 million increase in amortization of deferred financing fees primarily due to the write-off of fees related to the early repayment of two ECA loans in June 2013; and

• a $1.3 million decrease in capitalized interest reflecting the final aircraft delivery from our A330 program in April 2012.

Selling, general and administrative expenses for the six months endedJune 30, 2013 increased slightly over the same period in 2012. Non-cash share based expense was $2.1 million and $1.9 million for the six months endedJune 30, 2012 and 2013, respectively.

Impairment of aircraft was $6.2 million for the six months endedJune 30, 2013 as compared to $10.1 million for the six months endedJune 30, 2012. See "Summary of Impairments" below for a detailed discussion of the related impairment charges for these aircraft.

37

Other income:

Total other income for the six months endedJune 30, 2013 was $26.7 million as compared to $3.7 million for the same period in 2012. The increase was due to a $19.5 million increase on gain on sale of flight equipment and a $2.3 million increase related to the mark to market value of an undesignated interest rate derivative.

Income tax provision

Our provision for income taxes for the six months endedJune 30, 2012 and 2013 was $4.3 million and $7.3 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 $3.0 million for the six months endedJune 30, 2013 as compared to the same period in 2012 was primarily attributable to an increase in operating income subject to tax in the U.S. and Ireland.

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. We also 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, those subsidiaries that are resident in Ireland are subject to Irish tax.

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.

Other comprehensive income was $85.9 million for the six months endedJune 30, 2013, an increase of $1.7 million from the $84.1 million of other comprehensive income for the six months endedJune 30, 2012. Other comprehensive income for the six months endedJune 30, 2013 primarily consisted of:

• $55.9 million of net income;

• $12.0 million gain from a change in fair value of interest rate derivatives, net of taxes which is due primarily to net settlements for the six months endedJune 30, 2013 partially offset by a slight loss due to a downward shift in the one-month LIBOR forward curve; and

• $18.0 million of amortization of deferred net losses reclassified into earnings related to terminated interest rate derivatives.

Other comprehensive income for the six months endedJune 30, 2012 primarily consisted of:

• $48.9 million of net income;

• a $22.3 million gain from a change in fair value of interest rate derivatives, net of taxes which is due primarily to net settlements for the six months endedJune 30, 2012 partially offset by a slight loss due to a downward shift in the one-month LIBOR forward curve; and

• $12.9 million of amortization of deferred net losses reclassified into earnings related to terminated interest rate derivatives.

Summary of impairments

Recurring recoverability assessments are performed whenever events or changes in circumstances indicate that the net book value of our aircraft may not be recoverable, which may require us to change our assumptions related to future undiscounted cash flows. Events or changes in circumstances that we consider in our recoverability assessment include potential sales, lease amendments, extensions or transitions, aircraft portfolio considerations, aircraft type demand, emerging aircraft technology, residual values, useful lives and economic and market factors. Management evaluates a recoverability assessment of aircraft and performs this assessment annually during the third quarter of each year for all aircraft in our fleet on an aircraft-by-aircraft basis.

During the second quarter of 2012, we impaired two aircraft, one Boeing Model 757-200 aircraft that we sold for less than its net book value and one Boeing Model 767-300ER aircraft which was returned to us following its scheduled lease expiration and which failed its recoverability assessment. For these two aircraft, we recorded impairment charges of $10.1 million, and we recorded $2.4 million of maintenance revenue during the three and six months endedJune 30, 2012.

During the first quarter of 2013, we impaired two aircraft, one Airbus A319-100 aircraft and one Boeing 767-300ER aircraft, each of which was returned to us early by the respective lessee. The decision was made to sell these aircraft and the net book value of each was written down to the expected sale price. For these two aircraft, we recorded impairment charges totaling $6.2 million, and we recorded maintenance revenue of $9.0 million and other revenue of $0.9 million during the six months ended June 30, 2013.

At June 30, 2013, we had a total of 12 aircraft with a total net book value of $273.7 million (accounting for 5.7% of the total net book value of our flight equipment held for lease) that we consider more susceptible to failing our recoverability assessment. The recoverability in the value of these aircraft is more sensitive to changes in contractual cash flows, future cash flow estimates and aircraft residual or scrap values. These aircraft fall into the categories as shown in the table below:

Aircraft Type	Number of Aircraft	Percent of Net Book Value
Narrowbody	6	2.1%
Midbody	3	1.0%
Freighters	3	2.6%

PROPOSED ACCOUNTING PRONOUNCEMENTS

In May 2013, the Financial Accounting Standards Board (the "FASB") issued re-exposure draft, “Leases” (the “Lease Re-ED”), which would replace the existing guidance in the Accounting Standards Codification (“ASC”) 840 (“ASC 840”), Leases. The FASB decided that leases would be classified as either leases of property (Type B) or leases of assets other than property (Type A). Leases of property will continue to use operating lease accounting. Leases of other than property would use the receivable residual approach. Under the receivable residual approach, a lease receivable would be recognized for the lessor's right to receive lease payments, a portion of the carrying amount of the underlying asset would be allocated between the right of use granted to the lessee and the lessor's residual value and profit or loss would only be recognized at commencement if it is reasonably assured. The comment period for the Lease Re-ED ends September 13, 2013. We anticipate that the final standard may have an effective date no earlier than 2017. When and if the proposed guidance becomes effective, it may have a significant impact on the Company's consolidated financial statements. Although we believe the presentation of our financial statements, and those of our lessees could change, we do not believe the accounting pronouncement will change the fundamental economic reasons for which the airlines lease aircraft. Therefore, we do not believe it will have a material impact on our business.

LIQUIDITY AND CAPITAL RESOURCES

Our primary sources of liquidity currently are cash on hand, cash generated by our aircraft leasing operations, loans secured by new aircraft we acquire and unsecured borrowings. Our business is very capital intensive, requiring significant investments in order to expand our fleet during periods of growth and investments in maintenance and improvements on our existing portfolio. Our business also generates a significant amount of cash from operations, primarily from lease rentals and maintenance collections. These sources have historically provided liquidity for these investments and for other uses, including the payment of dividends to our shareholders. In the past, we have also met our liquidity and capital resource needs by utilizing several sources, including:

• lines of credit, our securitizations, term financings, secured borrowings supported by export credit agencies for new aircraft acquisitions and bank financings secured by aircraft purchases;

• unsecured indebtedness, including an unsecured revolving credit facility and unsecured senior notes;

• public offerings of common shares; and

• asset sales.

In early August 2013, we amended and restructured our existing $150.0 million 2012 Revolving Credit Facility with a new unsecured revolving credit facility (“the 2013 Revolving Credit Facility”).  The 2013 Revolving Credit Facility was initially sized at $335.0 million and can be increased to a maximum of $400.0 million.  The 2013 Revolving Credit Facility has a term of three years and is scheduled to expire in August 2016. The lending group consists of Citibank, N.A., Goldman Sachs Bank USA, JPMorgan Chase Bank, N.A., Royal Bank of Canada, DBS Bank Ltd., Los Angeles Agency, Credit Agricole and Investment Bank and Union Bank, N.A.

.

While the financing structures for our securitizations include liquidity facilities, these liquidity facilities are primarily designed to provide short-term liquidity to enable the financing vehicles to remain current on interest payments during periods when the relevant entities incur substantial unanticipated expenditures. Because these facilities have priority in the payment waterfall and therefore must be repaid quickly, and because we do not anticipate being required to draw on these facilities to cover operating expenses, we do not view these liquidity facilities as an important source of liquidity for us.

As of June 30, 2013, we are in compliance with all applicable covenants in our financings.

We believe that cash on hand, funds generated from operations, maintenance payments received from lessees, and proceeds from any 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 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

Net cash flow provided by operating activities	$	192,108		$	193,439
Net cash flow used in investing activities	(438,542		)	(45,408		)
Net cash flow (used in) provided by financing activities	241,974			(335,978		)

Operating Activities:

Cash flow from operations was $192.1 million and $193.4 million for the six months endedJune 30, 2012 and June 30, 2013, respectively. The increase in cash flow from operations of approximately $1.3 million for the six months endedJune 30, 2013 versus the same period in 2012 was primarily a result of:

• a $7.0 million increase in cash from finance leases;

40

• a $5.2 million increase in cash from working capital;

• a $2.7 million increase in cash from maintenance revenue; and

• a $1.1 million decrease in cash paid for taxes.

These inflows were offset partially by:

• a $17.2 million increase in cash paid for interest.

Investing Activities:

Cash used in investing activities was $438.5 million and $45.4 million for the six months endedJune 30, 2012 and June 30, 2013, respectively. The decrease in cash flow used in investing activities of $393.1 million for the six months endedJune 30, 2013 versus the same period in 2012, was primarily a result of:

• a $217.9 million increase in the proceeds from the sale of flight equipment;

• a $82.5 million decrease in the net investment in finance leases;

• a $43.6 million decrease in purchase of debt investments;

• a $38.8 million increase in principal repayments on debt investments; and

• a $22.1 million decrease in aircraft purchase deposits and progress payments.

These inflows were offset partially by:

• a $6.2 million increase in the acquisition and improvement of flight equipment; and

• a $4.8 million decrease in restricted cash and cash equivalents related to sale of flight equipment.

Financing Activities:

Cash provided by financing activities was $242.0 million for the six months endedJune 30, 2012 as compared to cash used in financing activities of $336.0 million for the six months endedJune 30, 2013. The net increase in cash flow used in financing activities of $578.0 million for the six months endedJune 30, 2013 versus the same period in 2012 was a result of:

• a $877.1 million of lower proceeds from notes and debt financings;

• a $186.6 million of lower restricted cash and cash equivalents related to security deposits and maintenance payments; and

• a $5.8 million of increased purchases of our common shares.

The increases were offset partially by:

• a $394.4 million of lower securitization and term debt repayments primarily due to the repayment of $583.1 million for Term Financing No. 1 in April 2012;

•a $50.8 million of lower payments for terminated cash flow hedges;

•a $21.6 million of higher maintenance deposits received net of maintenance deposits returned;

•a $17.2 million of lower deferred financing costs; and

•a $8.5 million of higher security deposits received net of security deposits returned.

ECA Term Financings

In June 2013, we repaid in full the outstanding principal balances on two of our ECA term financings in the total amount of $111.7 million, plus accrued interest, interest rate derivative breakage fees of $3.0 million, and accrued interest on the terminated interest rate derivatives. During the second quarter of 2013, we wrote off $3.8 million of deferred financing fees which is reflected in interest expense on the consolidated statement of income. We sold an additional aircraft in June 2013, and we posted cash, which is reflected in restricted cash and cash equivalents on the consolidated balance sheet, as collateral for the related term loan until we pay-off the loan or substitute an aircraft.

Bank Financings

In May 2013, we assumed three floating rate loans and one fixed rate loan totaling $91.8 million in connection with the acquisition of two Airbus Model A320-200 aircraft and two Boeing Model 737-800 aircraft. At June 30, 2013, these four loans had a weighted average interest rate of 1.65% and mature in 2018 and 2020.

We include these loan facilities in “Bank Financings”. Aircastle Limited has guaranteed the repayment of these Bank Financings.

As of June 30, 2013, we are in compliance with all applicable covenants in all of our financings.

Contractual Obligations

Our contractual obligations consist of principal and interest payments on variable and fixed rate liabilities, interest payments on interest rate derivatives, other aircraft acquisition and conversion agreements and rent payments pursuant to our office leases. Total contractual obligations decreased from $4.64 billion at December 31, 2012 to approximately $4.47 billion at June 30, 2013 due primarily to:

•an increase in purchase obligations for three aircraft to be acquired during the remainder of 2013; and

•an increase in the amount of bank financings for the purchase of four aircraft in May 2013.

This increase was partially offset by principal and interest payments made under our securitizations, ECA term financings and our Bank financings and the pay-off of two ECA term financings in June 2013.

(1) Estimated principal payments for these non-recourse financings are based on excess cash flows available from forecasted lease rentals, net maintenance funding and proceeds from asset dispositions after the payment of forecasted operating expenses and interest payments, including interest payments on existing interest rate derivative agreements and policy provider fees.

(2) Includes scheduled principal payments based upon eight fixed rate, 12-year, fully amortizing loans and one floating rate loan.

(3) Includes principal payments based upon individual loan amortization schedules.

(4) Future interest payments on variable rate, LIBOR-based debt obligations are estimated using the interest rate in effect at June 30, 2013.

(5) Future interest payments on derivative financial instruments are estimated using the spread between the floating interest rates and the fixed interest rates in effect at June 30, 2013.

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

(7) At June 30, 2013, we had commitments to acquire three aircraft. Since June 30, 2013, we made additional commitments to acquire four aircraft for $371.2 million, for total commitments of $512.2 million.

Capital Expenditures

We make capital expenditures from time to time in connection with improvements made to 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 six months endedJune 30, 2012 and 2013, we incurred a total of $24.2 million and $11.2 million, respectively, of capital expenditures (including lease incentives) related to the acquisition and improvement of aircraft.

As of June 30, 2013, the weighted average age (by net book value) of our aircraft was approximately 10.8 years. In general, the costs of operating an aircraft, including maintenance expenditures, increase with the age of the aircraft. Under our leases, the lessee is 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. At June 30, 2013, we had a $400.2 million maintenance payment liability on our balance sheet, which is a $20.8 million increase from December 31, 2012. The increase consisted of net maintenance cash inflows of $16.5 million and an increase in lease incentive liabilities of $4.3 million. 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.

44

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.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of June 30, 2013.

Foreign Currency Risk and Foreign Operations

At June 30, 2013, 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 six months endedJune 30, 2013, expenses, such as payroll and office costs, denominated in currencies other than the U.S. dollar aggregated approximately $6.3 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, it is likely that our international operations and our exposure to foreign currency risk will 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 six months endedJune 30, 2012 and 2013, we incurred insignificant net gains and losses on foreign currency transactions.

Hedging

The objective of our hedging policy is to adopt a risk averse position with respect to changes in interest rates. Accordingly, we have entered into a number of interest rate derivatives to hedge the current and expected future interest rate payments on our variable rate debt. Interest rate derivatives are agreements in which a series of interest rate cash flows are exchanged with a third party over a prescribed period. The notional amount on an interest rate derivative is not exchanged. Our interest rate derivatives typically provide that we make fixed rate payments and receive floating rate payments to convert our floating rate borrowings to fixed rate obligations to better match the largely fixed rate cash flows from our investments in flight equipment.

We held the following interest rate derivatives as of June 30, 2013: 

45

	Derivative Liabilities
Hedged Item	Current Notional Amount		Effective Date	Maturity Date	Future Maximum Notional Amount		Floating Rate	Fixed Rate	Balance Sheet Location	Fair Value
	(Dollars in thousands)
Interest rate derivatives designated as cash flow hedges:
Securitization No. 1	$	227,698	Jun-06	Jun-16	$	227,698	1M LIBOR + 0.27%	5.78%	Fair value of derivative liabilities	$	29,191
Securitization No. 2	525,806		Jun-12	Jun-17	525,806		1M LIBOR	1.26% to 1.28%	Fair value of derivative liabilities	6,265
Total interest rate derivatives designated as cash flow hedges	$	753,504			$	753,504				$	35,456
Interest rate derivatives not designated as cash flow hedges:
Securitization No. 1	89,627		Jun-06	Jun-16	89,627		1M LIBOR + 0.27%	5.78%	Fair value of derivative liabilities	11,490
Total interest rate derivatives not designated as cash flow hedges	89,627				89,627					11,490
Total interest rate derivative liabilities	$	843,131			$	843,131				$	46,946

The weighted average interest pay rates of these derivatives at December 31, 2012 and June 30, 2013 were 2.91%, and 2.97%, respectively.

For the six months endedJune 30, 2013, the amount of loss reclassified from accumulated other comprehensive income (“OCI”) into interest expense related to net interest settlements on active interest rate derivatives was $9.2 million. The amount of loss expected to be reclassified from OCI into interest expense over the next 12 months related to net interest settlements on active interest rate derivatives is $16.4 million.

Our interest rate derivatives involve counterparty credit risk. As of June 30, 2013, our interest rate derivatives are held with the following counterparties: JP Morgan Chase Bank NA, Citibank Canada NA, and Wells Fargo Bank NA. All of our counterparties or guarantors of these counterparties are considered investment grade (senior unsecured ratings of Baa2 or above) by Moody’s Investors Service. All are also considered investment grade (long-term foreign issuer ratings of A- or above) by Standard and Poor’s. We do not anticipate that any of these counterparties will fail to meet their obligations.

In addition to the derivative liability above, another component of the fair value of our interest rate derivatives is accrued interest. As of June 30, 2013, accrued interest payable included in accounts payable, accrued expenses, and other liabilities on our consolidated balance sheet was $0.8 million related to interest rate derivatives designated as cash flow hedges and $0.2 million related to interest rate derivatives not designated as cash flow hedges.

On an ongoing basis, terminated interest rate derivative notionals are evaluated against debt forecasts. To the extent that interest payments are deemed remote to occur, deferred gains or losses are accelerated into interest expense as applicable.

The following table summarizes the deferred (gains) and losses and related amortization into interest expense for our terminated interest rate derivative contracts for the six months endedJune 30, 2012 and 2013:

(1) On April 4, 2012, upon the repayment of Term Financing No. 1, both interest rate derivatives were terminated resulting in a net deferred loss of $50,429 which is being amortized into interest expense using the interest rate method.

For the six months endedJune 30, 2013, the amount of deferred net loss (including $2.0 million of accelerated amortization driven by aircraft sales in 2013) reclassified from OCI into interest expense related to our terminated interest rate derivatives was $17.2 million. The amount of deferred net loss expected to be reclassified from OCI into interest expense over the next 12 months related to our terminated interest rate derivatives is $25.8 million of which $16.9 million relates to Term Financing No. 1 interest rate derivatives terminated in April 2012, $1.4 million relates to Term Financing No. 1 interest rate derivatives terminated in 2008, $6.2 million relates to ECA Term Financings for New A330 Aircraft and $1.3 million relates to other financings.

For the six months endedJune 30, 2013, the amount of effective deferred loss reclassified from OCI into interest expense related to our undesignated active interest rate derivative was $0.7 million. The amount of effective deferred loss expected to be reclassified from OCI into interest expense over the next 12 months related to our undesignated active interest rate derivative under our Securitization No. 1 is $1.7 million.

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-US 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 and six months endedJune 30, 2012 and 2013, respectively.

Management’s Use of Adjusted Net Income (“ANI”)

Beginning with our report for the quarter ended March 31, 2012, management, to be more consistent with reporting practices of peer aircraft leasing companies, has revised the calculation of ANI to no longer exclude gains (losses) on sales of assets, and to exclude non-cash share based payment expense in the calculation of ANI. Beginning with our quarterly report for the quarter ended June 30, 2012, we also excluded Term Financing No. 1 hedge loss amortization charges which will be reported in Interest, net on our consolidated statement of income from the calculation of ANI. The calculation of ANI for the three and six months endedJune 30, 2012 has been revised to be comparable with the current period presentation.

Management believes that ANI, when viewed in conjunction with the Company’s results under US GAAP and the below reconciliation, provides useful information about operating and period-over-period performance, and provides 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 and gains or losses related to flight equipment and debt investments.

The table below shows the reconciliation of net income to ANI for the three and six months endedJune 30, 2012 and 2013, respectively.

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-US GAAP measures to supplement our US 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 US GAAP measures of earnings. Material limitations in making the adjustments to our earnings to calculate EBITDA, Adjusted EBITDA and ANI, and using these non-US GAAP measures as compared to US GAAP net income, income 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;

50

• 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 related to Term Financing No. 1; 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, income from operations or cash flows provided by or used in operations as calculated and presented in accordance with US GAAP. You should not rely on these non-US GAAP measures as a substitute for any such US GAAP financial measure. We strongly urge you to review the reconciliations to US GAAP net income, 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 US 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

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.

As of June 30, 2013, a hypothetical 100-basis point increase/decrease in our variable interest rate on our borrowings would result in an interest expense increase/decrease of $2.2 million and $0.7 million, respectively, net of amounts received from our interest rate derivatives, over the next twelve months.

51

Item 4.    Controls and Procedures

Management’s Evaluation of Disclosure Controls and Procedures

The term “disclosure controls and procedures” is defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. 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 June 30, 2013. 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 June 30, 2013.

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting that occurred during the quarter ended June 30, 2013 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

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.

Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings allocated to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, distributed and undistributed earnings are allocated to both common shares and restricted common shares based on the total weighted average shares outstanding during the period as follows: 

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2013		2012		2013
Weighted-average shares:
Common shares outstanding	71,723,014		67,828,919		71,709,976		67,862,513
Restricted common shares	589,163		631,368		609,601		508,288
Total weighted-average shares	72,312,177		68,460,287		72,319,577		68,370,801
Percentage of weighted-average shares:
Common shares outstanding	99.19	%	99.08	%	99.16	%	99.26	%
Restricted common shares	0.81	%	0.92	%	0.84	%	0.74	%
Total	100.00	%	100.00	%	100.00	%	100.00	%

The calculations of both basic and diluted earnings per share are as follows: 

	Three Months Ended June 30,						Six Months Ended June 30,

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

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 and liabilities as of December 31, 2012 and June 30, 2013 that we measured at fair value on a recurring basis by level within the fair value hierarchy. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to their fair value measurement. 

			Fair Value Measurements at December 31, 2012 Using Fair Value Hierarchy

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 interest rate derivatives included in Level 2 consist of United States dollar-denominated interest rate derivatives, and their fair values are determined by applying standard modeling techniques under the income approach to relevant market interest rates (cash rates, futures rates, swap rates) in effect at the period close to determine appropriate reset and discount rates and incorporates an assessment of the risk of non-performance by the interest rate derivative counterparty in valuing derivative assets and an evaluation of the Company’s credit risk in valuing derivative liabilities.

The following tables reflect the activity for the classes of our assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three and six months endedJune 30, 2012 and 2013, respectively:

For the three and six months endedJune 30, 2012, we had no transfers into or out of Level 3; however we did terminate all Level 3 interest rate derivatives during the second quarter of 2012. For the three and six months endedJune 30, 2013, we had no transfers into or out of Level 3; however we did settle the debt investment during the first quarter of 2013.

We measure the fair value of certain assets and liabilities on a non-recurring basis, when US 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 aircraft. We record aircraft at fair value when we determine the carrying value may not be recoverable. Fair value measurements for aircraft impaired are based on an income approach that uses Level 3 inputs, which include our assumptions and appraisal data as to future cash proceeds from leasing and selling aircraft.

During the second quarter of 2012, we impaired two aircraft, one Boeing Model 757-200 aircraft that we sold for less than its net book value and one Boeing Model 767-300ER aircraft which was returned to us following its scheduled lease expiration and which failed its recoverability assessment. For these two aircraft, we recorded impairment charges of $10,111, and we recorded $2,447 of maintenance during the three and six months endedJune 30, 2012.

During the first quarter of 2013, we impaired two aircraft, one Airbus A319-100 aircraft and one Boeing 767-300ER aircraft, each of which was returned to us early by the respective lessee. The decision was made to sell these aircraft and the net book value of each was written down to the expected sale price. For these two aircraft, we recorded impairment charges totaling $6,199 and recorded maintenance revenue of $9,019 and other revenue of $876 during the six months endedJune 30, 2013.

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 values of our securitizations which contain third party credit enhancements are estimated using a discounted cash flow analysis, based on our current incremental borrowing rates of borrowing arrangements that do not contain third party credit enhancements. The fair values of our ECA term financings and bank financings are estimated using a discounted cash flow analysis, based on our current incremental borrowing rates for similar types of borrowing arrangements. The fair value of our Senior Notes is estimated using quoted market prices.

 The carrying amounts and fair values of our financial instruments at December 31, 2012 and June 30, 2013 are as follows:

	December 31, 2012						June 30, 2013
	Carrying  Amount of Asset (Liability)			Fair Value of Asset (Liability)			Carrying  Amount of Asset (Liability)			Fair Value of Asset (Liability)
Securitizations and term debt financings	$	(1,082,368	)	$	(962,960	)	$	(934,335	)	$	(861,778	)

Senior Notes	(1,750,642		)	(1,905,565		)	(1,750,585		)	(1,874,190		)

All of our financial instruments are classified as Level 2 with the exception of our Senior Notes, which are classified as Level 1.

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

Income taxes have been provided for based upon 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 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.

The sources of income from continuing operations before income taxes for the three and six months endedJune 30, 2012 and 2013 were as follows: 

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2013		2012		2013
U.S. operations	$	357	$	791	$	681	$	1,196
Non-U.S. operations	17,313		35,795		52,520		62,038
Total	$	17,670	$	36,586	$	53,201	$	63,234

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. We also 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.

The consolidated income tax expense for the three and six months endedJune 30, 2012 and 2013 was determined based upon estimates of the Company's consolidated effective income tax rates for the years ending December 31, 2012 and 2013, respectively.

The Company's effective tax rate for the three and six months endedJune 30, 2012 was 7.6% and 8.0%, respectively, compared to 10.2% and 11.6%, respectively, for the three and six months endedJune 30, 2013. Movements in the effective tax rates are due primarily to changes in the proportion of the Company's earnings in taxable and non-tax jurisdictions. Because the geographic mix of pre-tax profits and losses in interim periods may not be reflective of full year results, this distorts our interim period effective tax rate.

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

	Three Months Ended June 30,						Six Months Ended June 30,
	2012			2013			2012			2013
Notional U.S. federal income tax expense (benefit) at the statutory rate	$	6,184		$	12,805		$	18,620		$	22,132

Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Organization and Basis of Presentation

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 investing in aviation assets, including leasing, managing and selling commercial jet aircraft to airlines throughout the world and investing in aircraft related debt investments.

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 (“US GAAP”). We operate in a single segment.

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 US 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, 2012.

The Company’s management has reviewed and evaluated all events or transactions for potential recognition and/or disclosure since the balance sheet date of June 30, 2013 through the date on which the consolidated financial statements included in this Form 10-Q were issued.

Principles of Consolidation

Principles of Consolidation

The consolidated financial statements include the accounts of Aircastle and all of its subsidiaries. Aircastle consolidates eight 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.

Effective January 1, 2013, the Company adopted Financial Accounting Standards Board (the "FASB") Accounting Standards Update ("ASU") 2013-02 (“ASU 2013-02”) Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This ASU requires that companies present reclassification adjustments for each component of accumulated other comprehensive income (“AOCI”) either on the face of the financial statements or in the notes, provided that all required information is presented in a single location. ASU 2013-02 is effective for interim and annual reporting periods beginning after December 15, 2012 and should be applied prospectively. The adoption of ASU 2013-02 did not have a material impact on the Company's consolidated financial statements.

Effective January 1, 2013, the Company adopted ASU 2011-11 (“ASU 2011-11”) Balance Sheet (Topic 210) Disclosures about Offsetting Assets and Liabilities. This ASU requires that companies disclose information to enable users of its financial statements to evaluate the effect or potential effect of netting arrangements on its financial position. ASU 2011-11 is effective for interim and annual reporting periods beginning on or after January 1, 2013 and should be applied retrospectively for all periods presented on the balance sheet. The adoption of ASU 2011-11 did not have a material impact on the Company's consolidated financial statements.

Risk and Uncertainties

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. Market risk reflects the change in the value of derivatives and financings due to changes in interest rate spreads or other market factors, including the value of collateral underlying derivatives and financings. Aviation industry risk is the risk of a downturn in the commercial aviation industry which could adversely impact a lessee’s ability to make payments, increase the risk of unscheduled lease terminations and depress lease rates and the value of the Company’s aircraft. Capital market risk is the risk that the Company is unable to obtain capital at reasonable rates to fund the growth of our business or to refinance existing debt facilities.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with US 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.

Description of New Accounting Pronouncements Not yet Adopted [Text Block]

Proposed Accounting Pronouncements

In May 2013, the FASB issued re-exposure draft, “Leases” (the “Lease Re-ED”), which would replace the existing guidance in the Accounting Standards Codification (“ASC”) 840 (“ASC 840”), Leases. The FASB decided that leases would be classified as either leases of property (Type B) or leases of assets other than property (Type A). Leases of property will continue to use operating lease accounting. Leases of other than property would use the receivable residual approach. Under the receivable residual approach, a lease receivable would be recognized for the lessor's right to receive lease payments, a portion of the carrying amount of the underlying asset would be allocated between the right of use granted to the lessee and the lessor's residual value and profit or loss would only be recognized at commencement if it is reasonably assured. The comment period for the Lease Re-ED ends September 13, 2013. We anticipate that the final standard may have an effective date no earlier than 2017. When and if the proposed guidance becomes effective, it may have a significant impact on the Company's consolidated financial statements. Although we believe the presentation of our financial statements, and those of our lessees could change, we do not believe the accounting pronouncement will change the fundamental economic reasons for which the airlines lease aircraft. Therefore, we do not believe it will have a material impact on our business.

In July 2013, we issued 12,320,000 of our common shares, par value US$0.01, at a price of $17.00 per share to an affiliate of Marubeni Corporation, a Japanese corporation (the "Investor"). In June 2013, we also entered into a Shareholder Agreement with the Investor, which became effective in July 2013 upon the closing of the issuance.

In early August 2013, we amended and restructured our existing $150,000 2012 Revolving Credit Facility with a new unsecured revolving credit facility (“the 2013 Revolving Credit Facility”).  The 2013 Revolving Credit Facility was initially sized at $335,000 and can be increased to a maximum of $400,000.  The 2013 Revolving Credit Facility has a term of three years and is scheduled to expire in August 2016. The lending group consists of Citibank, N.A., Goldman Sachs Bank USA, JPMorgan Chase Bank, N.A., Royal Bank of Canada, DBS Bank Ltd., Los Angeles Agency, Credit Agricole Corporate and Investment Bank and Union Bank, N.A.

Summary of Significant Accounting Policies

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 investing in aviation assets, including leasing, managing and selling commercial jet aircraft to airlines throughout the world and investing in aircraft related debt investments.

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 (“US GAAP”). We operate in a single segment.

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 US 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, 2012.

The Company’s management has reviewed and evaluated all events or transactions for potential recognition and/or disclosure since the balance sheet date of June 30, 2013 through the date on which the consolidated financial statements included in this Form 10-Q were issued.

Principles of Consolidation

The consolidated financial statements include the accounts of Aircastle and all of its subsidiaries. Aircastle consolidates eight 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.

Effective January 1, 2013, the Company adopted Financial Accounting Standards Board (the "FASB") Accounting Standards Update ("ASU") 2013-02 (“ASU 2013-02”) Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This ASU requires that companies present reclassification adjustments for each component of accumulated other comprehensive income (“AOCI”) either on the face of the financial statements or in the notes, provided that all required information is presented in a single location. ASU 2013-02 is effective for interim and annual reporting periods beginning after December 15, 2012 and should be applied prospectively. The adoption of ASU 2013-02 did not have a material impact on the Company's consolidated financial statements.

Effective January 1, 2013, the Company adopted ASU 2011-11 (“ASU 2011-11”) Balance Sheet (Topic 210) Disclosures about Offsetting Assets and Liabilities. This ASU requires that companies disclose information to enable users of its financial statements to evaluate the effect or potential effect of netting arrangements on its financial position. ASU 2011-11 is effective for interim and annual reporting periods beginning on or after January 1, 2013 and should be applied retrospectively for all periods presented on the balance sheet. The adoption of ASU 2011-11 did not have a material impact on the Company's consolidated financial statements.

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. Market risk reflects the change in the value of derivatives and financings due to changes in interest rate spreads or other market factors, including the value of collateral underlying derivatives and financings. Aviation industry risk is the risk of a downturn in the commercial aviation industry which could adversely impact a lessee’s ability to make payments, increase the risk of unscheduled lease terminations and depress lease rates and the value of the Company’s aircraft. Capital market risk is the risk that the Company is unable to obtain capital at reasonable rates to fund the growth of our business or to refinance existing debt facilities.

Use of Estimates

The preparation of financial statements in conformity with US 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.

Proposed Accounting Pronouncements

In May 2013, the FASB issued re-exposure draft, “Leases” (the “Lease Re-ED”), which would replace the existing guidance in the Accounting Standards Codification (“ASC”) 840 (“ASC 840”), Leases. The FASB decided that leases would be classified as either leases of property (Type B) or leases of assets other than property (Type A). Leases of property will continue to use operating lease accounting. Leases of other than property would use the receivable residual approach. Under the receivable residual approach, a lease receivable would be recognized for the lessor's right to receive lease payments, a portion of the carrying amount of the underlying asset would be allocated between the right of use granted to the lessee and the lessor's residual value and profit or loss would only be recognized at commencement if it is reasonably assured. The comment period for the Lease Re-ED ends September 13, 2013. We anticipate that the final standard may have an effective date no earlier than 2017. When and if the proposed guidance becomes effective, it may have a significant impact on the Company's consolidated financial statements. Although we believe the presentation of our financial statements, and those of our lessees could change, we do not believe the accounting pronouncement will change the fundamental economic reasons for which the airlines lease aircraft. Therefore, we do not believe it will have a material impact on our business.

During the second quarter of 2013, we wrote off $3,825 of deferred financing fees which is reflected in interest expense on the consolidated statement of income. We sold an additional aircraft in June 2013, and we posted cash, which is reflected in restricted cash and cash equivalents on the consolidated balance sheet, as collateral for the related term loan until we pay-off the loan or substitute an aircraft.

Bank Financings

In May 2013, we assumed three floating rate loans and one fixed rate loan totaling $91,797 in connection with the acquisition of two Airbus Model A320-200 aircraft and two Boeing Model 737-800 aircraft. At June 30, 2013, these four loans had a weighted average interest rate of 1.65% and mature in 2018 and 2020.

We include these loan facilities in “Bank Financings”. Aircastle Limited has guaranteed the repayment of these Bank Financings.

As of June 30, 2013, we are in compliance with all applicable covenants in all of our financings.

Variable Interest Entities

Aircastle consolidates eight 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 18 aircraft discussed below.

Securitizations

In connection with Securitization No. 1, two of our subsidiaries, ACS Aircraft Finance Ireland plc (“ACS Ireland”) and ACS Aircraft Finance Bermuda Limited (“ACS Bermuda”) issued Class A-1 notes, and each has fully and unconditionally guaranteed the other’s obligations under the notes. In connection with Securitization No. 2, two of our subsidiaries, ACS Aircraft Finance Ireland 2 Limited (“ACS Ireland 2”) and ACS 2007-1 Limited (“ACS Bermuda 2”) issued Class A-1 notes and each has fully and unconditionally guaranteed the other’s obligations under the notes. ACS Bermuda and ACS Bermuda 2 are collectively referred to as the “ACS Bermuda Group.”

Aircastle is the primary beneficiary of ACS Ireland and ACS Ireland 2 (collectively, the “ACS Ireland VIEs”), as we have both 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 Class E-1 Securities. Although Aircastle has not guaranteed the ACS Ireland VIEs debt, Aircastle wholly owns the ACS Bermuda Group which has fully and unconditionally guaranteed the ACS Ireland VIEs obligations. The activity that most significantly impacts the economic performance is the leasing of aircraft. Aircastle Advisor (Ireland) Limited (Aircastle’s wholly owned subsidiary) is the remarketing servicer and is responsible for the leasing of the aircraft. An Irish charitable trust owns 95% of the common shares of the ACS Ireland VIEs. The Irish charitable trust’s risk is limited to its annual dividend of $2 per VIE. At June 30, 2013, the assets of the two VIEs include 11 aircraft transferred into the VIEs at historical cost basis in connection with Securitization No. 1 and Securitization No. 2.

The combined assets of the ACS Ireland VIEs as of June 30, 2013 are $325,611. The combined liabilities of the ACS Ireland VIEs, net of $72,068 Class E-1 Securities held by the Company, which is eliminated in consolidation, as of June 30, 2013 are $278,978.

ECA Term Financings

Aircastle, through various subsidiaries, each of which is owned by a charitable trust (such entities, collectively the “Air Knight VIEs”), entered into eleven different twelve-year term loans, which are supported by guarantees from Compagnie Francaise d’ Assurance pour le Commerce Exterieur, (“COFACE”), the French government sponsored export credit agency (“ECA”). These loans provided for the financing for eleven new Airbus Model A330-200 aircraft. In June 2011, we repaid one of these loans from the proceeds of the sale of the related aircraft. In June 2013, we repaid two of these loans from the proceeds of the sale of the related aircraft. We sold an additional aircraft in June 2013, and we posted cash, which is reflected in restricted cash and cash equivalents on the consolidated balance sheet, as collateral for the related term loan until we pay-off the loan or substitute an aircraft. At June 30, 2013, Aircastle had eight outstanding term loans with guarantees from COFACE. We refer to these COFACE-supported financings as “ECA Term 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 and deferred financing costs. The related aircraft, with a net book value as of June 30, 2013 were $585,646, are included in our flight equipment held for lease. The consolidated debt outstanding of the Air Knight VIEs as of June 30, 2013 is $515,034.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

Derivatives

The objective of our hedging policy is to adopt a risk averse position with respect to changes in interest rates. Accordingly, we have entered into a number of interest rate derivatives to hedge the current and expected future interest rate payments on our variable rate debt. Interest rate derivatives are agreements in which a series of interest rate cash flows are exchanged with a third party over a prescribed period. The notional amount on an interest rate derivative is not exchanged. Our interest rate derivatives typically provide that we make fixed rate payments and receive floating rate payments to convert our floating rate borrowings to fixed rate obligations to better match the largely fixed rate cash flows from our investments in flight equipment.

We held the following interest rate derivatives as of June 30, 2013: 

	Derivative Liabilities
Hedged Item	Current Notional Amount		Effective Date	Maturity Date	Future Maximum Notional Amount		Floating Rate	Fixed Rate	Balance Sheet Location	Fair Value
Interest rate derivatives designated as cash flow hedges:
Securitization No. 1	$	227,698	Jun-06	Jun-16	$	227,698	1M LIBOR + 0.27%	5.78%	Fair value of derivative liabilities	$	29,191
Securitization No. 2	525,806		Jun-12	Jun-17	525,806		1M LIBOR	1.26% to 1.28%	Fair value of derivative liabilities	6,265
Total interest rate derivatives designated as cash flow hedges	$	753,504			$	753,504				$	35,456
Interest rate derivatives not designated as cash flow hedges:
Securitization No. 1	89,627		Jun-06	Jun-16	89,627		1M LIBOR + 0.27%	5.78%	Fair value of derivative liabilities	11,490
Total interest rate derivatives not designated as cash flow hedges	89,627				89,627					11,490
Total interest rate derivative liabilities	$	843,131			$	843,131				$	46,946

The weighted average interest pay rates of these derivatives at December 31, 2012 and June 30, 2013 were 2.91% and 2.97%, respectively.

For the six months endedJune 30, 2013, the amount of loss reclassified from accumulated other comprehensive income (“OCI”) into interest expense related to net interest settlements on active interest rate derivatives was $9,241. The amount of loss expected to be reclassified from OCI into interest expense over the next 12 months related to net interest settlements on active interest rate derivatives is $16,375.

Our interest rate derivatives involve counterparty credit risk. As of June 30, 2013, our interest rate derivatives are held with the following counterparties: JP Morgan Chase Bank NA, Citibank Canada NA, and Wells Fargo Bank NA. All of our counterparties or guarantors of these counterparties are considered investment grade (senior unsecured ratings of Baa2 or above) by Moody’s Investors Service. All are also considered investment grade (long-term foreign issuer ratings of A- or above) by Standard and Poor’s. We do not anticipate that any of these counterparties will fail to meet their obligations.

In addition to the derivative liability above, another component of the fair value of our interest rate derivatives is accrued interest. As of June 30, 2013, accrued interest payable included in accounts payable, accrued expenses, and other liabilities on our consolidated balance sheet was $802 related to interest rate derivatives designated as cash flow hedges and $185 related to interest rate derivatives not designated as cash flow hedges.

Following is the effect of interest rate derivatives on the statement of financial performance for the six months endedJune 30, 2013: 

Effective Portion				Ineffective Portion
Derivatives in ASC 815 Cash Flow Hedging Relationships	Amount of Gain or (Loss) Recognized in OCI on Derivative (a)	Location of Gain or (Loss) Reclassified from Accumulated OCI into Income	Amount of Gain or (Loss) Reclassified from Accumulated OCI into Income (b)	Location of Gain or (Loss) Recognized in Income on Derivative	Amount of Gain or (Loss) Recognized in Income on Derivative (c)
Interest rate derivatives	$2,959	Interest expense	$(26,979)	Interest expense	$(106)

(a) This represents the change in fair market value of our interest rate derivatives since year end, net of taxes, offset by the amount of actual cash paid related to the net settlements of the interest rate derivatives for the six months endedJune 30, 2013.

(b) This represents the amount of actual cash paid, net of taxes, related to the net settlements of the interest rate derivatives for the six months endedJune 30, 2013 plus any effective amortization of net deferred interest rate derivative losses.

(c) This represents both realized and unrealized ineffectiveness incurred during the six months endedJune 30, 2013.

Derivatives Not Designated as Hedging Instruments under ASC 815	Location of Gain or (Loss) Recognized in Income On Derivative	Amount of Gain or (Loss) Recognized in Income on Derivative
Interest rate derivatives	Other income (expense)	$	2,872

On an ongoing basis, terminated swap notionals are evaluated against debt forecasts. To the extent that interest payments are deemed remote to occur, deferred gains or losses are accelerated into interest expense as applicable.

For the six months endedJune 30, 2013, the amount of deferred net loss (including $2,027 of accelerated amortization driven by aircraft sales in 2013) reclassified from OCI into interest expense related to our terminated interest rate derivatives was $17,240. The amount of deferred net loss expected to be reclassified from OCI into interest expense over the next 12 months related to our terminated interest rate derivatives is $25,782 of which $16,899 relates to Term Financing No. 1 interest rate derivatives terminated in 2012, $1,373 relates to Term Financing No. 1 derivatives terminated in 2008, $6,166 relates to ECA Term Financings for New A330 Aircraft and $1,344 relates to other financings.

For the six months endedJune 30, 2013, the amount of effective deferred loss reclassified from OCI into interest expense related to our undesignated active interest rate derivative was $745. The amount of effective deferred loss expected to be reclassified from OCI into interest expense over the next 12 months related to our undesignated active interest rate derivative under our Securitization No. 1 is $1,678.

The following table summarizes amounts charged directly to the consolidated statement of income for the three and six months endedJune 30, 2012 and 2013, respectively, related to our interest rate derivatives:
