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 one segment. The Company’s management has reviewed and evaluated all events or transactions for potential recognition and/or disclosure since the balance sheet date of December 31, 2012 through the date on which the consolidated financial statements included in this Form 10-K were issued. Effective January 1, 2012, the Company adopted Financial Accounting Standards Board (the “FASB”) Accounting Standards Update (“ASU”) ASU 2011-04 (“ASU 2011-04”), Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurements and Disclosure Requirements in U.S. GAAP and IFRSs, to improve the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with US GAAP and IFRS. The amendments in this update change the wording used to describe the requirements in US GAAP for measuring fair value and for disclosing information about fair value measurements which include (1) those that clarify the FASB's intent about the application of existing fair value measurement and disclosure requirements, and (2) those that change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurement. ASU 2011-04 is effective for interim and annual reporting periods beginning after December 15, 2011. The adoption of ASU 2011-04 did not have a material impact on the Company's consolidated financial statements. Also effective January 1, 2012, the Company adopted ASU 2011-12 (“ASU 2011-12”) Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05. This ASU defers the ASU 2011-05 requirement that companies present reclassification adjustments for each component of accumulated other comprehensive income (“AOCI”) in both net income and other comprehensive income (“OCI”) on the face of the financial statements. During the deferral period, there is no requirement to separately present or disclose the reclassification adjustments into net income. The FASB expects to issue a final standard in January 2013, with an effective date after December 15, 2012. ASU 2011-12 is effective for interim and annual reporting periods beginning after December 15, 2011 and should be applied retrospectively. The adoption of ASU 2011-12 did not have a material impact on the Company's consolidated financial statements. | ||||||||||||
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of Aircastle and all of its subsidiaries. Aircastle consolidates nine 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. | ||||||||||||
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. | ||||||||||||
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents | Cash and Cash Equivalents and Restricted Cash and Cash Equivalents Aircastle considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. Restricted cash and cash equivalents consists primarily of rent collections, maintenance payments and security deposits received from lessees pursuant to the terms of various lease agreements held in lockbox accounts in accordance with our financings. Changes in restricted cash and cash equivalents related to rent collections are reflected within operating activities of our consolidated statements of cash flows for non-cash trapped financings. Changes in restricted cash and cash equivalents related to rent collections are reflected within financing activities of our consolidated statements of cash flows for cash trapped financings. Changes in restricted cash related to the sale of flight equipment are reflected within investing activities of our consolidated statements of cash flows. Changes in restricted cash and cash equivalents related to maintenance payments and security deposits are reflected within financing activities of our consolidated statements of cash flows. Virtually all of our cash and cash equivalents and restricted cash and cash equivalents are held by four major financial institutions. | ||||||||||||
Flight Equipment Held for Lease and Depreciation | Flight Equipment Held for Lease and Depreciation Flight equipment held for lease is stated at cost and depreciated using the straight-line method, typically over a 25-year life from the date of manufacture for passenger aircraft and over a 30- to 35-year life for freighter aircraft, depending on whether the aircraft is a converted or purpose-built freighter, to estimated residual values. Estimated residual values are generally determined to be approximately 15% of the manufacturer’s estimated realized price for passenger aircraft when new and 5% - 10% for freighter aircraft when new. Management may make exceptions to this policy on a case-by-case basis when, in its judgment, the residual value calculated pursuant to this policy does not appear to reflect current expectations of value. Examples of situations where exceptions may arise include but are not limited to:
Major improvements and modifications incurred in connection with the acquisition of aircraft that are required to get the aircraft ready for initial service are capitalized and depreciated over the remaining life of the flight equipment. For planned major maintenance activities for aircraft off-lease, the Company capitalizes the actual maintenance costs by applying the deferral method. Under the deferral method, we capitalize the actual cost of major maintenance events, which are depreciated on a straight-line basis over the period until the next maintenance event is required. In accounting for flight equipment held for lease, we make estimates about the expected useful lives, the fair value of attached leases, acquired maintenance liabilities and the estimated residual values. In making these estimates, we rely upon actual industry experience with the same or similar aircraft types and our anticipated lessee’s utilization of the aircraft. When we acquire an aircraft with a lease, determining the fair value of attached leases requires us to make assumptions regarding the current fair values of leases for specific aircraft. We estimate a range of current lease rates of like aircraft in order to determine if the attached lease is within a fair value range. If a lease 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 amortized into lease rental income over the remaining term of the lease. | ||||||||||||
Impairment of Flight Equipment | Impairment of Flight Equipment We perform a recoverability assessment of all aircraft in our fleet, on an aircraft-by-aircraft basis, at least annually. In addition, a recoverability assessment is performed whenever events or changes in circumstances, or indicators, indicate that the carrying amount or net book value of an asset may not be recoverable. Indicators may include, but are not limited to, a significant lease restructuring or early lease termination, significant air traffic decline, the introduction of newer technology aircraft or engines, an aircraft type is no longer in production or a significant airworthiness directive is issued. When we perform a recoverability assessment, we measure whether the estimated future undiscounted net cash flows expected to be generated by the aircraft exceed its net book value. The undiscounted cash flows consist of cash flows from currently contracted leases, future projected lease rates, transition costs, estimated down time and estimated residual or scrap values for an aircraft. In the event that an aircraft does not meet the recoverability test, the aircraft will be adjusted to fair value, resulting in an impairment charge. See Note 2. — Fair Value Measurements. Management develops the assumptions used in the recoverability analysis based on current and future expectations of the global demand for a particular aircraft type and historical experience in the aircraft leasing market and aviation industry, as well as information received from third party industry sources. The factors considered in estimating the undiscounted cash flows are impacted by changes in future periods due to changes in contracted lease rates, residual values, economic conditions, technology, airline demand for a particular aircraft type and other factors. In monitoring the aircraft in our fleet for impairment charges, we identify those aircraft that are most susceptible to failing the recoverability assessment and monitor those aircraft more closely, which may result in more frequent recoverability assessments. The recoverability in the value of these aircraft is more sensitive to changes in contractual cash flows, future cash flow estimates and residual values or scrap values for each aircraft. These are typically older aircraft for which lessee demand is declining. | ||||||||||||
Net Investment in Finance Leases | Net Investment in Finance Leases If a lease meets specific criteria at the inception of a new lease or at any lease modification date, we recognize the lease as a Net investment in finance leases on our Consolidated Balance Sheets. The Net investment in finance leases consists of lease receivables, less the unearned income, plus the estimated unguaranteed residual value of the leased flight equipment at the lease end date. The unearned income is recognized as Other revenue in our Consolidated Statements of Income over the lease term in a manner that produces a constant rate of return on the Net investment in finance lease. Collectability of finance leases is evaluated periodically on an individual customer level. The evaluation of the collectability of the finance leases considers the credit of the lessee and the value of the underlying aircraft. An allowance for credit losses is established if there is evidence that we will be unable to collect all amounts due according to the original contractual terms of the Net investment in finance leases. At December 31, 2012, we had no allowance for credit losses for our Net investment in finance leases. | ||||||||||||
Capitalization of Interest | Capitalization of Interest We capitalize interest related to progress payments made in respect of flight equipment on forward order and on prepayments made in respect of the conversion of passenger-configured aircraft to freighter-configured aircraft, and add such amount to prepayments on flight equipment. The amount of interest capitalized is the actual interest costs incurred on funding specific assets or the amount of interest costs which could have been avoided in the absence of such payments for the related assets. | ||||||||||||
Security Deposits | Security Deposits Most of our operating leases require the lessee to pay Aircastle a security deposit or provide a letter of credit. Security deposits represent cash received from the lessee that is held on deposit until lease expiration. Aircastle’s operating leases also obligate the lessees to maintain flight equipment and comply with all governmental requirements applicable to the flight equipment, including without limitation, operational, maintenance, registration requirements and airworthiness directives. | ||||||||||||
Maintenance Payments | Maintenance Payments Typically, under an operating lease, the lessee is responsible for performing all maintenance but might be required to make deposit 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 are required to be made monthly in arrears or at the end of the lease term. Whether to permit a lessee to make maintenance payments at the end of the lease term, rather than requiring such payments to be made monthly, depends on a variety of factors, including the creditworthiness of the lessee, the level of security deposit which may be provided by the lessee and market conditions at the time we enter into the lease. If a lessee is making monthly maintenance payments, we would typically be obligated to reimburse the lessee for costs they incur for heavy maintenance, overhaul or replacement of certain high-value components to the extent of maintenance payments received in respect of the specific maintenance event, usually shortly following completion of the relevant work. We record maintenance payments paid by the lessee as accrued maintenance payments liabilities in recognition of our contractual commitment to refund such receipts. In these contracts, we do not recognize such maintenance payments as maintenance revenue during the lease. Reimbursements to the lessee upon the receipt of evidence of qualifying maintenance work are charged against the existing accrued maintenance payments liability. We currently defer maintenance revenue recognition of all maintenance reserve payments collected until the end of the lease, when we are able to determine the amount, if any, by which reserve payments received exceed costs to be incurred by the current lessee in performing scheduled maintenance. | ||||||||||||
Lease Incentives and Amortization | Lease Incentives and Amortization Many of our leases contain provisions which may require us to pay a portion of the lessee’s costs for heavy maintenance, overhaul or replacement of certain high-value components. We account for these expected payments as lease incentives, which are amortized as a reduction of revenue over the life of the lease. We estimate the amount of our portion for such costs, typically for the first major maintenance event for the airframe, engines, landing gear and auxiliary power units, expected to be paid to the lessee based on assumed utilization of the related aircraft by the lessee, the anticipated amount of the maintenance event cost 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. Lease acquisition costs related to reconfiguration of the aircraft cabin, other lessee specific modifications and other direct costs are capitalized and amortized into revenue over the initial life of the lease, assuming no lease renewals, and are included in other assets. | ||||||||||||
Income Taxes | Income Taxes Aircastle uses an asset and liability based approach in accounting for income taxes. Deferred income tax assets and liabilities are recognized for the future tax consequences attributed to differences between the financial statement and tax basis of existing assets and liabilities using enacted rates applicable to the periods in which the differences are expected to affect taxable income. A valuation allowance is established, when necessary, to reduce deferred tax assets to the amount estimated by us to be realizable. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities. We did not have any unrecognized tax benefits. | ||||||||||||
Derivative Financial Instruments | Derivative Financial Instruments In the normal course of business we utilize interest rate derivatives to manage our exposure to interest rate risks. Specifically, our interest rate derivatives are hedging variable rate interest payments on our various debt facilities. If certain conditions are met, an interest rate derivative may be specifically designated as a cash flow hedge. All of our designated interest rate derivatives are cash flow hedges. We have one interest rate derivative that is not designated for accounting purposes. On the date that we enter into an interest rate derivative, we formally document the intended use of the interest rate derivative and its designation as a cash flow hedge, if applicable. We also assess (both at inception and on an ongoing basis) whether the interest rate derivative has been highly effective in offsetting changes in the cash flows of the variable rate interest payments on our debt and whether the interest rate derivative is expected to remain highly effective in future periods. If it were to be determined that the interest rate derivative is not (or has ceased to be) highly effective as a cash flow hedge, we would discontinue cash flow hedge accounting prospectively. At inception of an interest rate derivative designated as a cash flow hedge, we establish the method we will use to assess effectiveness and the method we will use to measure any ineffectiveness. Historically, we have elected to use the “change in variable cash flows method” for both. This method involves a comparison of the present value of the cumulative change in the expected future cash flows on the variable leg of the interest rate derivative against the present value of the cumulative change in the expected future interest cash flows on the variable-rate debt. When the change in the interest rate derivative’s variable leg exceeds the change in the debt’s variable-rate interest cash flows, the calculated ineffectiveness is recorded in interest expense on our consolidated statement of income. Effectiveness is assessed by dividing the change in the interest rate derivative variable leg by the change in the debt’s variable-rate interest cash flows. We use the “hypothetical trade method” for interest rate derivatives designated as cash flow hedges subsequent to inception that did not qualify for the “change in variable cash flow method.” The calculation involves a comparison of the change in the fair value of the interest rate derivative to the change in the fair value of a hypothetical interest rate derivative with critical terms that reflect the hedged variable-rate debt. The effectiveness of these relationships is assessed by regressing historical changes in the interest rate derivative against historical changes in the hypothetical interest rate derivative. When the change in the interest rate derivative exceeds the change in the hypothetical interest rate derivative, the calculated ineffectiveness is recorded in interest expense on our consolidated statement of income. All interest rate derivatives are recognized on the balance sheet at their fair value. We determine fair value for our United States dollar-denominated interest rate derivatives by calculating reset rates and discounting cash flows based on cash rates, futures rates and swap rates in effect at the period close. We determine the fair value of our United States dollar-denominated guaranteed notional balance interest rate derivatives based on the upper notional band using cash flows discounted at relevant market interest rates in effect at the period close. See Note 2 — Fair Value Measurements for more information. For our interest rate derivatives designated as cash flow hedges, the effective portion of the interest rate derivative’s gain or loss is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the interest payments on the debt are recorded in earnings. The ineffective portion of the interest rate derivative is calculated and recorded in interest expense on our consolidated statement of income at each quarter end. For any interest rate derivative not designated as a cash flow hedge, the gain or loss is recognized in other income (expense) on our consolidated statement of income. We may choose to terminate certain interest rate derivatives prior to their contracted maturities. Any related net gains or losses in accumulated other comprehensive income at the date of termination are not reclassified into earnings if it remains probable that the interest payments on the debt will occur. The amounts in accumulated other comprehensive income are reclassified into earnings as the interest payments on the debt affect earnings. Terminated interest rate derivatives are reviewed periodically to determine if the forecasted transactions remain probable of occurring. To the extent that the occurrence of the interest payments on the debt are deemed remote, the related portion of the accumulated other comprehensive income balance is reclassified into earnings immediately. | ||||||||||||
Lease Revenue Recognition | Lease Revenue Recognition We lease flight equipment under net operating leases with lease terms typically ranging from 3 to 7 years. We generally do not offer renewal terms or purchase options in our leases, although certain of our operating leases allow the lessee the option to extend the lease for an additional term. Operating leases with fixed rentals and step rentals are recognized on a straight-line basis over the term of the initial lease, assuming no renewals. Operating lease rentals that adjust based on a London Interbank Offered Rate (“LIBOR”) index are recognized on a straight-line basis over the period the rentals are fixed and accruable. Revenue is not recognized when collection is not reasonably assured. When collectability is not reasonably assured, the customer is placed on non-accrual status, and revenue is recognized when cash payments are received. | ||||||||||||
Comprehensive Income | Comprehensive Income Comprehensive income consists of net income and other gains and losses, net of income taxes, if any, affecting shareholders’ equity that, under US GAAP, are excluded from net income. At December 31, 2012, such amount consists of the effective portion of fluctuations in the fair value of derivatives designated as cash flow hedges. | ||||||||||||
Share Based Compensation | Share Based Compensation Aircastle recognizes compensation cost relating to share-based payment transactions in the financial statements based on the fair value of the equity instruments issued. Aircastle uses the straight line method of accounting for compensation cost on share-based payment awards that contain pro-rata vesting provisions. | ||||||||||||
Deferred Financing Costs | Deferred Financing Costs Deferred financing costs, which are included in other assets in the Consolidated Balance Sheet, are amortized using the interest method for amortizing loans over the lives of the relevant related debt. | ||||||||||||
Leasehold Improvements, Furnishings and Equipment | Leasehold Improvements, Furnishings and Equipment Improvements made in connection with the leasing of office facilities are capitalized as leasehold improvements and are amortized on a straight line basis over the minimum lease period. Furnishings and equipment are capitalized at cost and are amortized over the estimated life of the related assets or remaining lease terms, which range between 3 and 5 years. | ||||||||||||
Recent Unadopted Accounting Pronouncements | Recent Unadopted Accounting Pronouncements In August 2010, the FASB issued an exposure draft, “Leases” (the “Lease ED”), which would replace the existing guidance in the Accounting Standards Codification (“ASC”) 840 (“ASC 840”), Leases. In June 2012, the FASB decided that leases would be classified as either leases of property or leases of assets other than property. 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 FASB completed all of its deliberations and decided to re-expose the Lease ED in the first half of 2013. We anticipate that the final standard may have an effective date no earlier than 2016. 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. |
