[1]	We recorded $10,053 during 2013 and $2,636 during 2012 in Paid-in capital for compensation expenses, legal expenses and other expenses paid by AIG on our behalf for which we were not required to reimburse. Additionally, we recorded $16,690, net of tax of $9,211, in Paid-in capital during 2012 when AIG contributed a corporate aircraft to us.
[2]	In 2013, we transferred shares of AIG stock with a carrying value, net of tax, of $0.9 million to AIG and recorded the transaction as a decrease to Retained earnings. In 2012, we recorded a decrease to Retained earnings of $25,379, net of tax of $11,866 when we transferred two corporate aircraft to AIG, and an increase to Retained earnings of $(4) for other miscellaneous adjustments.
[3]	The decrease to Retained earnings during the period beginning January 1, 2014 and ending May 13, 2014, included a special distribution of $600,000, which ILFC was required to pay to AIG prior to the completion of the AerCap Transaction in accordance with the Share Purchase Agreement. See Note 3bAerCap Transaction. The special distribution was recorded in Retained earnings as a dividend.
[4]	We recorded an increase of $296, net of tax of $161, in connection with settlement of the AIG Non-Qualified Income Plan liability, and a decrease of $233 for adjustments to state taxes payable.
[5]	The increase to Retained earnings during the period beginning January 1, 2014 and ending May 13, 2014, reflects a $9,626 receipt from AIG for certain expected separate company tax liabilities, as required under the AerCap sales agreement, partially offset by decreases in Retained earnings of $5,298, net of tax of $2,889, to record a non-cash dividend reflecting the difference between the proceeds received and the net carrying value of a corporate aircraft sold to AIG, and $1,370 recorded as a dividend, for a fee ILFC paid on behalf of AIG to satisfy a statutory law requirement.

Basis of Preparation	1. Basis of Preparation
	AerCap Trust, a Delaware statutory trust, was formed on February 5, 2014. On the Closing Date, immediately after completing the AerCap Transaction, all of ILFC's assets were transferred substantially as an entirety to, and substantially all of ILFC's liabilities were assumed by, AerCap Trust. AerCap Ireland Capital Limited, a wholly-owned subsidiary of AerCap Ireland Limited, and ILFC, an indirect wholly-owned subsidiary of AerCap Trust, are the sole beneficiaries of AerCap Trust. Neither AerCap Ireland Limited nor AerCap Ireland Capital Limited are consolidated into the financial statements presented herein, but are related parties to the consolidated AerCap Trust. AerCap Trust, AerCap Ireland Capital Limited, AerCap Ireland and ILFC are all direct or indirect wholly-owned subsidiaries of AerCap.
	In connection with the Reorganization, ILFC entered into amendments to certain of its debt agreements which, in part, provide that AerCap Trust succeed ILFC as the issuer under these debt agreements, while ILFC has also agreed to remain an obligor under the debt agreements.
	Prior to May 14, 2014, ILFC was an indirect wholly-owned subsidiary of AIG. On December 16, 2013, AIG entered into an agreement with AerCap and AerCap Ireland Limited, a wholly-owned subsidiary of AerCap, for the sale of 100 percent of ILFC's common stock.
	Following the completion of the AerCap Transaction, we measured the identifiable assets acquired, the liabilities assumed, and non-controlling interest at the Closing Date fair value by applying the acquisition method of accounting. Accordingly, a new basis of accounting was established and, for accounting purposes the old entity, the Predecessor, was terminated and a new entity, the Successor, was created. Predecessor represents ILFC and its consolidated subsidiaries' historical accounting basis and covers the time period prior to May 14, 2014. Successor represents AerCap Trust from its inception on February 5, 2014 and ILFC and its subsidiaries consolidated with AerCap Trust for the time period from May 14, 2014, reflecting the assets and liabilities at fair value by allocating the purchase price to the identifiable assets acquired and liabilities assumed and non-controlling interest pursuant to accounting guidance related to business combinations. The distinction between these periods has been indicated in this Annual Report by the inclusion of a vertical line between the Predecessor and Successor columns of our financial statements and in the notes thereto. These separate periods are presented in order to reflect our new accounting basis as of the Closing Date, after applying the acquisition method of accounting. Results presented for periods subsequent to the AerCap Transaction reflect Successor accounting policies. The timing and amount of revenues and expenses recognized in results of operations and the classification of amounts recorded in the financial statements in periods subsequent to the Closing Date may differ from Predecessor's presentation. Consequently, the financial statements and notes for the Predecessor periods are not comparable to the Successor periods. Despite the separate presentation, our core operations have not changed (see Note 3 for further information on the AerCap Transaction).
	The accompanying Consolidated Financial Statements include our accounts and accounts of all other entities in which we have a controlling financial interest. See Note 25—Variable Interest Entities for discussions of VIEs. All material intercompany accounts have been eliminated in consolidation.
	Predecessor results for the year ended December 31, 2013 include out of period adjustments related to prior periods, which decreased pre-tax loss by approximately $10.7 million and decreased after-tax loss by approximately $13.4 million. The pre-tax out of period adjustments for the year ended December 31, 2013, primarily relate to, among others, (i) $19.5 million decrease to pre-tax loss due to favorable adjustments to interest expense to correct and fully align amortization of deferred debt issuance costs and debt discounts in prior periods with the effective interest method; (ii) a $3.7 million increase to pre-tax loss to correctly reflect legal expenses previously paid by AIG on our behalf; and (iii) $5.5 million increase to pre-tax loss to correct lease revenue to fully align amortization of prepaid lease costs on certain leases with early termination options. After-tax results for the year ended December 31, 2013, were also favorably impacted by $8.3 million for the reversal of IRS audit interest expense amounts in the first quarter of 2013 that were incorrectly recognized in the fourth quarter 2011 tax provision.
	Management has determined, after evaluating the quantitative and qualitative aspects of these out of period adjustments, both individually and in the aggregate, that our current and prior period financial statements are not materially misstated.
	As discussed further in Note 3—AerCap Transaction, during the measurement period, following the Closing Date, we have made certain adjustments to the estimated fair values of identifiable assets acquired and liabilities assumed as of the Closing Date. The adjustments to the Successor opening balance sheet impacted financial results for the June and September 2014 unaudited interim periods. As a result, we have provided revised June and September 2014 financial information herein. See Note 3—AerCap Transaction and Note 30—Quarterly Financial Information (Unaudited).
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Certain amounts have been reclassified in the 2013 and 2012 Consolidated Statements of Operations and the Consolidated Statements of Cash Flows to conform to our Predecessor 2014 presentation. These reclassifications are not material to our financial statements. Certain information presented for Successor is not presented for Predecessor herein, as the information was not previously provided for the Predecessor in this format.

	Following the completion of the AerCap Transaction, the results reflect the Successor's accounting policies. The timing and amount of revenues and expenses recognized in results of operations and the classification of amounts recorded in the financial statements in periods subsequent to the Closing Date may differ from the Predecessor presentation. Accordingly, we have listed our significant accounting policies applicable to both the Successor and Predecessor below.
	Significant Accounting Policies of the Successor
	Principles of Consolidation: The accompanying consolidated financial statements include the results of all entities in which we have a controlling financial interest, including VIEs for which we are the PB. The PB is the entity that has both (i) the power to direct the activities of the VIE that most significantly affect the entity's economic performance and (ii) the obligation to absorb losses or the right to receive benefits that could be potentially significant to the VIE. See Note 25—Variable Interest Entities.
	Use of estimates: The preparation of Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. For us, the use of estimates is or could be a significant factor affecting acquisition accounting in a business combination, the reported carrying values of flight equipment, intangibles, investments, trade and notes receivable, deferred tax assets and accruals and reserves. Management considers information available from professional appraisers, where possible, to support estimates, particularly with respect to flight equipment. Despite management's best efforts to accurately estimate such amounts, actual results could materially differ from those estimates.
	Cash and cash equivalents: Cash and cash equivalents include cash and highly liquid investments with an original maturity of three months or less.
	Restricted cash: Restricted cash includes cash held by banks that is subject to withdrawal restrictions. Such amounts are typically restricted under secured debt agreements and can be used only to service the aircraft securing the debt and to make principal and interest payments on the debt.
	Trade receivables: Trade receivables represent unpaid, current lessee obligations under existing lease contracts. Allowances are provided for doubtful accounts where the risk of non-recovery is probable. The risk of non-recovery is primarily based on the extent to which amounts outstanding exceed the value of security held, together with an assessment of the financial strength and condition of a debtor and the economic conditions persisting in the debtor's operating environment.
	Flight equipment held for operating leases, net: Flight equipment held for operating leases, including aircraft, is stated at cost less accumulated depreciation and impairment. Flight equipment is depreciated to its estimated residual value using the straight-line method over the assets' useful life, generally 25 years from the date of manufacture, or different period depending on the disposition strategy. The costs of improvements to flight equipment are normally expensed unless the improvement increases the long-term value of the flight equipment or extends the useful life of the flight equipment. The capitalized cost is depreciated over the estimated remaining useful life of the aircraft. The current estimates for residual values for most aircraft types are 15 percent of original manufacture cost, in line with industry standards, except where more recent industry information indicates a different value is appropriate.
	We review estimated useful lives and residual values of aircraft periodically based on our knowledge and external factors coupled with market conditions to determine if they are appropriate and record adjustments to depreciation prospectively on an aircraft by aircraft basis as necessary.
	On a quarterly basis, we evaluate the need to perform a recoverability assessment when events or changes in circumstances indicate that the carrying value of our long-lived assets may not be recoverable. When a recoverability assessment is required, the review for recoverability includes an assessment of the estimated future cash flows associated with the use of an asset and its eventual disposal. The assets are grouped at the lowest level for which identifiable cash flows are largely independent of other groups of assets. In relation to flight equipment on operating lease, the impairment assessment is performed on each individual aircraft, including lease related assets and liabilities. If the sum of the expected undiscounted future cash flows is less than the carrying amount of the asset, an impairment is recognized. The loss is measured as the excess of the carrying amount of the impaired asset over its fair value.
	Fair value reflects the present value of cash expected to be generated from the aircraft in the future, including its expected residual value discounted at a rate commensurate with the associated risk. Future cash flows are assumed to occur under then current market conditions and assume adequate time for a sale between a willing buyer and a willing seller. Expected future lease rates are based on all relevant information available, including current contracted rates for similar aircraft, appraisal data and industry trends.
	Annually, we perform an impairment assessment for all of our aircraft, including a review of the undiscounted cash flows for aircraft 15 years of age, or older, as the cash flows supporting the carrying value of such older aircraft are more dependent upon current lease contracts, which leases are more sensitive to weaknesses in the global economic environment. Deterioration of the global economic environment and a decrease of aircraft values might have a negative effect on the undiscounted cash flows of older aircraft and might trigger impairments.
	Capitalization of interest: We capitalize interest on Prepayments on flight equipment in respect of flight equipment on forward order and add such amount to Prepayments on flight equipment. The amount of interest capitalized is the actual interest costs incurred on funding specific to the prepayments, if any, or the amount of interest costs which could have been avoided in the absence of such prepayments.
	Net investment in finance and sales-type leases: If a lease meets specific criteria under U.S. GAAP, we recognize the lease in Net investment in finance and sales-type leases on our Consolidated Balance Sheets and de-recognize the aircraft from Flight equipment held for operating leases. For sales-type leases, we recognize the difference between the aircraft carrying value and the Net investment in finance and sales-type leases as a gain on sale of assets or an impairment. The amounts recognized for finance and sales-type leases consist of lease receivables and the estimated unguaranteed residual value of the leased flight equipment on the lease termination date, less the unearned income. Expected unguaranteed residual values of leased flight equipment are based on our assessment and independent appraisals of the values of the leased flight equipment at expiration of the lease terms. The unearned income is recognized in Lease revenue on our Consolidated Statements of Operations, over the lease term, in a manner that produces a constant rate of return on the lease.
	Maintenance rights intangible and lease premium, net: The maintenance rights intangible asset arose from the application of the acquisition method of accounting to aircraft and leases which were acquired in the AerCap Transaction and represented the fair value of our contractual aircraft return rights under our leases at the Closing Date. The maintenance rights intangible asset represents the contractual right under our leases to receive the aircraft in a specified maintenance condition at the end of the lease (EOL contracts) or our right to an aircraft in better maintenance condition by virtue of our obligation to contribute towards the cost of the maintenance events performed by the lessee either through reimbursement of maintenance deposit rents held (MR contracts), or through a lessor contribution to the lessee. The maintenance rights represented the difference between the specified maintenance return condition in our leases and the actual physical condition of our aircraft at the Closing Date.
	For EOL contracts, maintenance rights expense is recognized upon lease termination, to the extent the lease end cash compensation paid to us is less than the maintenance rights intangible asset. Maintenance rights expense is included in Leasing expenses in our Consolidated Statements of Operations. To the extent the lease end cash compensation paid to us is more than the maintenance rights intangible asset, revenue is recognized in Lease revenue in our Consolidated Statement of Operations, upon lease termination. For MR contracts, maintenance rights expense is recognized at the time the lessee provides us with an invoice for reimbursement relating to the cost of a qualifying maintenance event that relates to pre-acquisition usage.
	The lease premium represents the value of an acquired lease where the contractual rent payments are above the market rate. We amortize the lease premium on a straight-line basis over the term of the lease as a reduction of Lease revenue.
	Other definite-lived intangible assets: These primarily represent customer relationships recorded at fair value as a result of the AerCap Transaction. The rate of amortization of these definite-lived intangible assets is estimated based on the period over which we expect to derive economic benefits from such assets. The amortization expense is recorded in Depreciation and amortization on our Consolidated Statements of Operations. We evaluate all definite-lived intangible assets for impairment when events or changes in circumstances indicate that an intangible asset value may not be recoverable.
	Derivative financial instruments: We may use derivative financial instruments to manage our exposure to interest rate risks and foreign currency risks. Derivatives are recognized on the balance sheet at their fair value, which includes consideration of the credit rating and risk attaching to the counterparty of the derivative contract. We have considered both the quantitative and qualitative factors when determining our counterparty credit risk. We currently do not apply hedge accounting to our derivatives. Changes in fair value of derivatives are recorded in Interest expense in our Consolidated Statements of Operations.
	Net cash received or paid under derivative contracts in any reporting period is classified as operating cash flows in our Consolidated Statements of Cash Flows.
	Fair Value Measurements: Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We measure the fair value of our derivatives on a recurring basis and measure the fair values of aircraft, investment in finance and sales-type leases and asset value guarantees on a non-recurring basis. See Note 26—Fair Value Measurements.
	Other assets: Other assets consist of inventory, lease incentives, prepaid expenses, debt issuance costs, notes receivable, other receivables and other tangible fixed assets.
	Inventory consists primarily of engine and airframe parts we sell through our subsidiary, AeroTurbine. Inventory is valued at the lower of cost or market value. Cost is primarily determined using the specific identification method for individual part purchases and on an allocated basis for engines and aircraft purchased for disassembly and for bulk purchases. Costs are allocated using the relationship of the cost of the engine, aircraft, or bulk inventory purchase to the estimated retail sales value at the time of purchase. At the time of sale this ratio is applied to the sales price of each individual part to determine its cost. We periodically evaluate this ratio and, if necessary, update sales estimates and make adjustments to this ratio. Generally, inventory that is held for more than four years is considered excess inventory and its carrying value is reduced to zero.
	We capitalize amounts paid or value provided to lessees as lease incentives. We amortize lease incentives on a straight-line basis over the term of the related lease as a reduction of Lease revenue.
	Notes receivable represent amounts advanced in the normal course of our operations and also arise from the restructuring and deferral of trade receivables from lessees experiencing financial difficulties. Allowances are made for doubtful accounts where the risk of non-recovery is probable. The assessment of the risk of non-recovery where lessees are experiencing financial difficulties is primarily based on the extent to which amounts outstanding exceed the value of security held, together with an assessment of the financial strength and condition of the debtor and the economic conditions persisting in the debtor's operating environment.
	Other tangible fixed assets consist primarily of computer equipment, leasehold improvements and office furniture, and are valued at acquisition cost and depreciated at various rates over the asset's estimated useful life using the straight-line method. Depreciation expense on other tangible fixed assets is recorded in Depreciation and amortization on our Consolidated Statements of Operations.
	Accrued maintenance liability: Under our aircraft leases, the lessee is responsible for maintenance and repairs and other operating expenses related to our flight equipment during the term of the lease. In certain instances, such as when an aircraft is not subject to a lease, we may incur maintenance and repair expenses for our aircraft. Maintenance and repair expenses are recorded in Leasing expenses in our Consolidated Statements of Operations, to the extent such expenses are incurred by us.
	We may be obligated to make additional payments to the lessee for maintenance related expenses primarily related to usage of major life-limited components existing at the inception of the lease ("lessor maintenance contributions"). For all lease contracts that were not part of the AerCap Transaction, we expense planned major maintenance activities such as lessor maintenance contributions when incurred. The charge is recorded in Leasing expenses in our Consolidated Statements of Operations. In the case we have established an accrual as an assumed liability for such payment in connection with the purchase of an aircraft with a lease attached, such payments are charged against the existing accrual.
	For all contracts outstanding at the Closing Date, we determined the fair value of our maintenance liability, including lessor maintenance contributions, using the present value of the expected cash outflows. The discounted amounts are accreted in subsequent periods to their respective nominal values, up until the expected maintenance event dates, using the effective interest method. The accretion is recorded as an increase to Interest expense in our Consolidated Statements of Operations.
	Debt and Deferred Debt Issuance Costs: Long-term debt is carried at the principal amount borrowed, including unamortized discounts and premiums and fair value adjustments, where applicable. The fair value adjustments reflect the application of the acquisition method of accounting to the debt outstanding on the Closing Date. We amortize the amount of discount or premium and fair value adjustments over the period the debt is outstanding using the effective interest method. The costs we incur for issuing debt are capitalized and amortized as an increase to Interest expense over the life of the debt using the effective interest method.
	Lessee Security Deposits: On the Closing Date, we discounted our lessee security deposits to their respective present values. We accrete these discounted amounts to their respective nominal values, over the period we expect to refund the security deposits to each lessee, using the effective interest method, recognizing an increase to Interest expense.
	Revenue recognition: We lease flight equipment principally under operating leases and recognize rental income on a straight-line basis over the life of the lease. At lease inception, we review all necessary criteria to determine proper lease classification. We account for lease agreements that include step rent clauses on a straight-line basis. The difference between rental revenue recognized and the cash received is included in Other assets, and in the event it is a liability in Accrued expenses, accounts payable and other liabilities. In certain cases, leases provide for rentals contingent on usage. The usage may be calculated based on hourly usage or on the number of cycles operated, depending on the lease contract. Revenue contingent on usage is recognized at the time the lessee reports the usage to us.
	Lease agreements for which base rent is based on floating interest rates are included in minimum lease payments based on the floating interest rate existing at the inception of the lease; any increases or decreases in lease payments that result from subsequent changes in the floating interest rate are contingent rentals and are recorded as increases or decreases in Lease revenue in the period of the interest rate change.
	Our lease contracts normally include default covenants, which generally obligate the lessee to pay us damages to put us in the position we would have been in had the lessee performed under the lease in full. There are no additional payments required which would increase the minimum lease payments. We cease revenue recognition on a lease contract when the collectability of such rentals is no longer reasonably assured. For past-due rentals that exceed related security deposits held, which have been recognized as revenue, provisions are established on the basis of management's assessment of collectability. Such provisions are recorded in Selling, general and administrative expenses on the Consolidated Statements of Operations.
	Revenues from Net investment in finance and sales-type leases are included in Lease revenue in our Consolidated Statements of Operations and are recognized using the interest method to produce a constant yield over the life of the lease.
	Most of our lease contracts require payment in advance. Rentals received, but unearned under these lease agreements are recorded as deferred revenue on the balance sheet.
	Under our aircraft leases, the lessee is responsible for maintenance and repairs of our flight equipment and related expenses during the term of the lease. Under the provisions of many of our leases, the lessee is required to make payments of supplemental maintenance rents which are calculated with reference to the utilization of the airframe, engines and other major life-limited components during the lease. We record as revenue all supplemental maintenance rent receipts not expected to be reimbursed to lessees. We estimate the total amount of maintenance reimbursements for the entire lease and only record revenue after we have received enough maintenance rents under a particular lease to cover the total amount of estimated maintenance reimbursements during the remaining lease term. In these leases, upon lessee presentation of invoices evidencing the completion of qualifying maintenance on the aircraft, we make a payment to the lessee to compensate for the cost of the maintenance, up to the maximum of the supplemental maintenance rent payments made with respect to the lease contract.
	In most lease contracts not requiring the payment of supplemental maintenance rents, the lessee is generally required to re-deliver the aircraft in a similar maintenance condition (normal wear and tear excepted) as when accepted under the lease, with reference to major life-limited components of the aircraft. To the extent that such components are redelivered in a different condition than at acceptance, there is generally EOL cash compensation for the difference at redelivery. We recognize receipts of EOL cash compensation as Lease revenue when received to the extent those receipts exceed the EOL contract maintenance rights intangible asset and receipts of EOL compensation as Leasing expenses to the extent those receipts do not exceed EOL contract maintenance intangible asset.
	For all of our MR contracts, any amounts of accrued maintenance liability existing at the end of a lease are released and recognized as Lease revenue at lease termination. When flight equipment is sold, the portion of the accrued maintenance liability which is not specifically assigned to the buyer is released from the balance sheet, net of any Maintenance rights intangible asset balance, and recognized as Net gain on sale of assets as part of the sale of the flight equipment.
	Net gain on sale of assets originates primarily from the sale of aircraft and engines and are recognized when the delivery of the relevant asset is complete and the risk of loss has transferred to the buyer.
	Other income consists of interest income, management fees, lease termination penalties, and inventory part sales. Income from secured loans, notes receivable and other interest bearing instruments is recognized using the effective yield method as interest accrues under the associated contracts. Lease management fees are recognized as income as they accrue over the life of the contract. Income from the receipt of lease termination penalties is recorded at the time cash is received or when the lease is terminated, if collection is reasonably assured.
	Share-based compensation: Prior to the AerCap Transaction, certain of our employees participated in various AIG share-based compensation plans, and the associated expense reflects costs allocated to us by AIG. Subsequent to the AerCap Transaction, certain employees received AerCap share-based awards, consisting of restricted stock units and restricted stock. The amount of such expense is determined by reference to the fair value of the restricted stock units or restricted stock on the grant date. The share-based compensation expense is recognized over the vesting period using the straight-line method. See Note 22—Employee Benefit Plans and Share-Based and Other Compensation Plans.
	Foreign currencies: Foreign currency transactions are translated into U.S. dollars at the exchange rate prevailing at the time the transaction took place. Receivables or payables arising from such foreign currency transactions are remeasured into U.S. dollars at the exchange rate on each subsequent balance sheet date. All resulting exchange gains and losses are recorded in Selling, general and administrative expenses on the Consolidated Statements of Operations.
	Variable interest entities: We consolidate VIEs in which we have determined that we are the PB. We use judgment when determining (i) whether an entity is a VIE; (ii) who are the variable interest holders; (iii) the elements and degree of control that each variable interest holder has; and (iv) ultimately which party is the PB. When determining which party is the PB, we perform an analysis which considers (i) the design of the VIE; (ii) the capital structure of the VIE; (iii) the contractual relationships between the variable interest holders; (iv) the nature of the entities' operations; and (v) the purposes and interests of all parties involved, including related parties. While we consider these factors, our conclusion about whether to consolidate ultimately depends on the breadth of our decision-making ability and our ability to influence activities that significantly affect the economic performance of the VIE. We continually re-evaluate whether we are the PB for VIEs in which we hold a variable interest.
	Income Taxes: We recognize an uncertain tax benefit only to the extent that it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position.
	Deferred income tax assets and liabilities: We report deferred taxes resulting from the temporary differences between the book values and the tax values of assets and liabilities using the liability method. The differences are calculated at nominal value using the enacted tax rate applicable at the time the temporary difference is expected to reverse. Deferred tax assets attributable to unutilized losses carried forward or other timing differences are reduced by a valuation allowance if it is more likely than not that such losses will not be utilized to offset future taxable income.
	Reportable segments: We manage our business and analyze and report our results of operations on the basis of one business segment: leasing, financing, sales and management of commercial aircraft and engines.
	Significant Accounting Policies of the Predecessor
	Principles of Consolidation: The accompanying consolidated financial statements include the results of all entities in which we have a controlling financial interest, including VIEs for which we are the PB. The PB is the entity that has both (i) the power to direct the activities of the VIE that most significantly affect the entity's economic performance and (ii) the obligation to absorb losses or the right to receive benefits that could be potentially significant to the VIE.
	Variable Interest Entities: We consolidate VIEs in which we have determined that we are the PB. We use judgment when determining (i) whether an entity is a VIE; (ii) who are the variable interest holders; (iii) the elements and degree of control that each variable interest holder has; and (iv) ultimately which party is the PB. When determining which party is the PB, we perform an analysis which considers (i) the design of the VIE; (ii) the capital structure of the VIE; (iii) the contractual relationships between the variable interest holders; (iv) the nature of the entities' operations; and (v) the purposes and interests of all parties involved, including related parties. While we consider these factors, our conclusion about whether to consolidate ultimately depends on the breadth of our decision-making ability and our ability to influence activities that significantly affect the economic performance of the VIE. We continually re-evaluate whether we are the PB for VIEs in which we hold a variable interest.
	Lease Revenue: We lease flight equipment principally under operating leases and recognize rental revenue on a straight line basis over the life of the lease. The difference between the rental revenue recognized and the cash received under the provisions of our leases is included in Lease receivables and other assets and, in the event it is a liability, in Security deposits, deferred overhaul rental and other customer deposits on our Consolidated Balance Sheets. Past-due rental revenue is recognized on the basis of management's assessment of collectability. Management monitors all lessees that are behind in lease payments and evaluates lessee operational and financial issues to determine the amount of rental revenue to recognize for past due amounts. Our customers are required to make lease payments in advance and we generally recognize rental revenue only to the extent we have received payments or hold security deposits. In certain cases, leases provide for additional flight hour revenue based on usage. The usage may be calculated based on hourly usage or on the number of cycles operated, depending on the lease contract. A cycle is defined as one take-off and landing. The usage is typically reported monthly by the lessee. Rental revenue received under the lease agreements, but unearned, is included in Security deposits, deferred overhaul rental and other customer deposits on our Consolidated Balance Sheets.
	Lease revenues from the rental of flight equipment are reduced by the amortization of lease incentives, which primarily consist of our maintenance contributions to lessees in connection with the lease of used aircraft.
	Under the provisions of our leases, lessees are generally responsible for maintenance and repairs, including major maintenance (overhauls) over the term of the lease. Under the provisions of many of our leases, we receive overhaul rentals based on the usage of the aircraft, calculated based on number of hours or cycles operated. The usage is typically reported monthly by the lessee. For certain airframe and engine overhauls incurred by our lessees, we reimburse the lessee for costs up to, but not exceeding, related overhaul rentals that the lessee has paid to us.
	We recognize overhaul rentals received, net of estimated overhaul reimbursements, as revenue. We estimate expected overhaul reimbursements during the life of the lease, which requires significant judgment. Management determines the reasonableness of the estimated future overhaul reimbursement rate considering quantitative and qualitative information including (i) changes in historical pay-out rates from period to period; (ii) trends in reimbursements made; (iii) trends in historical pay-out rates for expired leases; (iv) future estimates of pay-out rates on leases scheduled to expire in the near term; (v) changes in our business model and portfolio strategies and (vi) other factors affecting the future pay-out rates that may occur from time to time. Changes in the expected overhaul reimbursement estimate result in an adjustment to the cumulative deferred overhaul rental balance sheet amount, which is recognized in current period results. If overhaul reimbursements are different than our estimates, or if estimates of future reimbursements change, there could be a material impact on our results of operations in a given period.
	Additionally, in connection with a lease of a used aircraft, we generally agree to contribute to certain maintenance events the lessee incurs during the lease. At the time we pay the agreed upon maintenance reimbursement, we record the reimbursement against deferred overhaul rentals, to the extent we have received overhaul rentals from the lessee, and against return condition deficiency deposits, to the extent received from the prior lessee. We capitalize as lease incentives any amount of the actual maintenance reimbursement we pay in excess of overhaul rentals paid to us by the lessee and payments received from prior lessees for deficiencies in return conditions and amortize the lease incentives as a reduction of revenues from Rental of flight equipment over the remaining life of the lease.
	Capitalized Major Maintenance Costs: When an aircraft is repossessed or when a lessee defaults on its lease obligations, we may be required to perform major maintenance on the aircraft. In these instances, if we have not received sufficient overhaul rentals under the lease, we capitalize the costs of the overhaul, to the extent that those costs meet the recognition criteria of an asset, and amortize those costs over the period until the next estimated overhaul event.
	Return Condition Payments: We may receive payments from our lessees at the conclusion of a lease, rather than requiring them to make the required repairs to meet return conditions. These return condition payments are generally negotiated to facilitate an efficient return of the aircraft, which generally results in the aircraft being delivered to the next lessee in a condition less than anticipated during the lease negotiations. The return condition payments are initially recognized as a liability in Security deposits, deferred overhaul rental and other customer deposits on our Consolidated Balance Sheets.
	Lease Incentive Costs: We capitalize as lease incentives any amounts paid by us to lessees or other parties in connection with the lease transactions. These amounts include the actual maintenance reimbursement we pay in excess of overhaul rentals and payments received from prior lessees for deficiencies in return conditions and lessee-specific aircraft cabin modifications. We amortize the lease incentives as a reduction of revenues from Rental of flight equipment over the remaining life of the lease.
	Flight Equipment Marketing and Gain on Aircraft Sales: Flight equipment marketing and gain on aircraft sales consists of commissions generated from the leasing and sales of managed aircraft and gains generated from the sale of flight equipment. Flight equipment sales are recognized when substantially all of the risks and rewards of ownership have passed to the new owner. Retained lessee obligations, if any, are recognized as reductions to Flight equipment marketing and gain on aircraft sales at the time of the sale.
	Cash and Cash Equivalents: We consider cash and cash equivalents with original maturity dates of 90 days or less to be cash on hand and highly liquid investments. At December 31, 2013, cash and cash equivalents consisted of cash on hand and time deposits.
	Restricted Cash: All cash unavailable for use in our operations is considered restricted cash. Such amounts are typically restricted under secured debt agreements and can be used only to service the aircraft securing the debt and to make principal and interest payments on the debt.
	Foreign Currency: Assets and liabilities denominated in foreign currencies are translated into US dollars using the exchange rates at the balance sheet date. Foreign currency transaction gains or losses are translated into US dollars using the average exchange rate during the period.
	Flight Equipment: Flight equipment is stated at cost. Purchases, major additions and modifications and interest on deposits during the construction phase are capitalized. We generally depreciate aircraft using the straight-line method over a 25-year life from the date of manufacture to an estimated residual value. At times, management may change useful lives or residual values of certain aircraft, as appropriate. Any such changes are accounted for on a prospective basis. As of December 31, 2013, 104 of our aircraft, with a net book value of $1.1 billion, are being depreciated over useful lives of less than 25-years from the date of manufacture. The weighted average useful life of these aircraft, weighted by the net book value of such aircraft, is 16.9 years.
Vendor Payments: As part of the purchase of new aircraft, aircraft engines and related equipment, we will often obtain payments from our vendors in the form of cash and other consideration ("vendor payments"). Generally, vendor payments are recognized as a reduction in the purchase price of aircraft, unless facts and circumstances indicate that the vendor payment was provided as compensation for a service provided by us or as a reimbursement of costs incurred by us to sell the vendor's products.
Impairments on Flight Equipment Held for Use: Management evaluates quarterly the need to perform a recoverability assessment of held for use aircraft considering the requirements under GAAP and performs this assessment at least annually for all aircraft in our fleet. Recoverability assessments are performed whenever events or changes in circumstances indicate that the carrying amount of our aircraft may not be recoverable. Some of these events or changes in circumstances may include potential disposals of aircraft (sales or part-outs), changes in contracted lease terms, changes in the lease status of an aircraft (leased, re-leased, or not subject to lease), repossessions of aircraft, changes in portfolio strategies, changes in demand for a particular aircraft type and changes in economic and market circumstances. Economic and market circumstances include the risk factors affecting the airline industry. Any of these events would be considered when it occurs before the financial statements are issued, including lessee bankruptcies occurring subsequent to the balance sheet date.
Recoverability of an aircraft's carrying amount is measured by comparing the carrying amount of the aircraft to the estimated future undiscounted cash flows expected to be generated by the aircraft. The undiscounted cash flows used in the recoverability assessment include the current contractual lease cash flows and projected future non-contractual lease cash flows, both of which include estimates of net overhaul rental collections, where appropriate, extended to the end of our estimated holding period, and an estimated disposition value for each aircraft. If the future undiscounted cash flows are less than the aircraft carrying amount, the aircraft is impaired and is re-measured to fair value in accordance with our Fair Value Policy. The difference between the fair value and the carrying amount of the aircraft is recognized as an impairment loss separately in our Consolidated Statements of Operations. Management is active in the aircraft leasing industry and develops the assumptions used in the recoverability assessment.
As part of our recurring recoverability assessment process, we update the critical and significant assumptions used in the recoverability assessment, including projected lease rates and terms, estimated net overhaul rental collections, residual values, and estimated aircraft holding periods. In updating these critical and significant assumptions, we consider (i) current and future expectations of the global demand for a particular aircraft type; (ii) the impact of fuel price volatility and higher average fuel prices; (iii) the growing impact of new technology aircraft; (iv) the higher production rates sustained by manufacturers of more fuel-efficient newer generation aircraft during the recent economic downturn; (v) the unfavorable impact of low rates of inflation on aircraft values; (vi) current market conditions and industry outlook for future marketing of older mid-generation aircraft and aircraft that are out of production; (vii) decreasing number of lessees for older aircraft; (viii) end-of-life management capabilities provided by our subsidiary, AeroTurbine; and (ix) events occurring subsequent to our balance sheet date that affect the value of our fleet.
Flight Equipment Held for Sale: We classify aircraft as Flight equipment held for sale when all the criteria under GAAP are met. Such amounts are included in Lease receivables and other assets on our Consolidated Balance Sheets. Aircraft classified as Flight equipment held for sale are recognized at the lower of their carrying amount or estimated fair value less estimated costs to sell. If the carrying amount of the aircraft exceeds its estimated fair value, then a fair value adjustment is recognized separately in our Consolidated Statements of Operations.
Management uses judgment in evaluating these criteria. Due to the significant uncertainties of potential sale transactions, the held for sale criteria generally will not be met unless the aircraft is subject to a signed sale agreement or management has made a specific determination and obtained appropriate approvals to sell a particular aircraft or group of aircraft. At the time aircraft are classified as Flight equipment held for sale, we cease recognizing depreciation expense.
We designate an aircraft for part-out when the aircraft is subject to an executed consignment agreement. At that time, we reclassify the aircraft from Flight equipment to Lease receivables and other assets at the lower of its carrying amount or estimated fair value less estimated costs to sell. At the time aircraft are classified as Lease receivables and other assets, the cost and accumulated depreciation are removed from Flight equipment.
Investment in finance and sales-type leases: If a lease meets specific criteria under GAAP at the inception of the lease, we recognize the lease in Net investment in finance and sales-type leases on our Consolidated Balance Sheets. For sales-type leases, we de-recognize the aircraft and any lease-related assets or liabilities from our Consolidated Balance Sheets and recognize the difference between the aircraft carrying value, including the lease-related assets or liabilities, and the Net investment in finance and sales-type leases as a gain or loss in our Consolidated Statements of Operations. The amounts recognized for finance and sales-type leases consist of lease receivables and the estimated unguaranteed residual value of the leased flight equipment on the lease termination date, less the unearned income. The unearned income is recognized as Other income in our Consolidated Statements of Operations over the lease term in a manner that produces a constant rate of return on the lease.
Allowance for Credit Losses: An allowance for credit losses is established if it is probable that we will be unable to collect all amounts due according to the original contractual terms of the finance and sales-type receivables and notes receivable ("financing receivables"). Financing receivables consist of net investment in finance and sales-type leases recognized as the gross investment in the lease, less unearned income, and notes receivable recognized at cost. The allowance for credit losses is reported as a reduction of the financing receivables carrying value on the Consolidated Balance Sheets. Additions to the allowance for credit losses are recognized in our Consolidated Statements of Operations in Selling, general and administrative expenses.
Collectability of financing receivables is evaluated periodically on an individual note and customer level. Financing receivables are considered impaired when we determine that it is probable that we will not be able to collect all amounts due according to the original contractual terms. Individual credit exposures are evaluated based on the realizable value of any collateral, and payment history. The estimated recoverable amount is the value of the expected future cash flows, including amounts that may be realized from the value of the collateral. Allowances for specific credit losses are established for the difference between the carrying amount and the estimated recoverable amount. The accrual of interest income based on the original terms of the financing receivable is discontinued based on the facts and circumstances of the individual credit exposure, and any future interest income is recognized based on cash receipts. Any subsequent changes to the amounts and timing of the expected future cash flows compared with the prior estimates result in a change in the allowance for credit losses and are charged or credited to Selling, general and administrative expense. An allowance is generally reversed only when cash is received in accordance with the original contractual terms of the note. A write-off of the financing receivable is made when recoverability has been abandoned or amounts have been forgiven. Write-offs are charged against previously established allowances for credit losses. Partial or full recoveries of amounts previously written off are credited to the provision for credit loss.
We also evaluate other receivables from customers periodically for collectability on an individual customer level. Allowances for specific credit losses are established for the difference between the carrying amount and the estimated recoverable amount. A write-off of other receivables is made when recoverability has been abandoned or amounts have been forgiven. Write-offs are charged against previously established allowances for credit losses. Partial or full recoveries of amounts previously written off are credited to the provision for credit loss.
Capitalized Interest: We borrow funds to finance progress payments for the construction of flight equipment ordered and capitalize the interest incurred on such borrowings in the cost of the flight equipment. This amount is calculated using our composite borrowing rate.
Deferred Debt Issue Costs and Debt Discounts and Premiums: The costs we incur for issuing debt are capitalized and amortized as an increase to interest expense over the life of the debt using the effective interest method. If we issue debt at a discount or premium, we amortize the amount of discount or premium over the life of the debt using the effective interest method.
Derivative Financial Instruments: From time to time, we may employ a variety of derivative financial instruments to manage our exposure to interest rate risks and foreign currency risks. Derivatives are recognized on our Consolidated Balance Sheets at fair value. AIG Markets, Inc., a related party, is the counterparty to all our interest rate swaps and foreign currency swaps. We apply either fair value or cash flow hedge accounting when transactions meet specified criteria for hedge accounting treatment. If the derivative does not qualify for hedge accounting, the change in fair value of the derivative is immediately recognized in earnings. If the derivative qualifies for hedge accounting and is designated and documented as a hedge, changes in the fair value of the hedge are either recognized in income along with changes in the fair value of the item being hedged for fair value hedges, or recognized in OCI to the extent the hedge is effective for cash flow hedges. We have elected to classify the cash flows from derivative instruments that have been designated as fair value or cash flow hedges in accordance with GAAP in the same category as the cash flows from the items being hedged.
At the time the derivative is designated as a hedge, we formally document the relationship between the hedging instrument and hedged item including risk management objectives and strategies for undertaking the hedge transactions. This includes linking the derivative designated as a fair value, a cash flow, or a foreign currency hedge to a specific asset or liability on the balance sheet. We also assess, both at the hedge's inception and on an ongoing basis, whether the hedge has been and is expected to be highly effective in offsetting changes in the fair value or cash flow of hedged item. We use the "hypothetical derivative method" when we assess the effectiveness of a hedge. When it is determined that a hedge has ceased to be highly effective as a hedge, we discontinue hedge accounting.
We discontinue hedge accounting prospectively when (i) we determine that the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item; (ii) the derivative expires or is sold, terminated, or exercised; or (iii) management determines that designating the derivative as a hedging instrument is no longer appropriate.
In all situations in which hedge accounting is discontinued and the derivative remains outstanding, we carry the derivative at its fair value on the balance sheet, recognizing changes in the fair value in current-period earnings. The remaining balance in AOCI at the time we discontinue hedge accounting for cash flow hedges is amortized into income over the remaining life of the previously hedged item. If the expected cash flows of the previously hedged item are no longer expected to occur, any related amounts remaining in AOCI would be immediately recognized in earnings.
Inventory: Our inventory consists primarily of engine and airframe parts and rotable and consumable parts and is included in Lease receivables and other assets on our Consolidated Balance Sheets. We value our inventory at the lower of cost or market. Cost is primarily determined using the specific identification method for individual part purchases and on an allocated basis for engines and aircraft purchased for disassembly and for bulk inventory purchases. Costs are allocated using the relationship of the cost of the engine, aircraft or bulk inventory purchase to the estimated retail sales value at the time of purchase. At the time of sale, this ratio is applied to the sales price of each individual part to determine its cost. We periodically evaluate this ratio and, if necessary, update sales estimates and make adjustments to this ratio. Generally, inventory that is held for more than four years is considered excess inventory and its carrying value is reduced to zero.
Goodwill and Other Acquired Intangible Assets: As a result of our acquisition of AeroTurbine, we recognized goodwill and other intangible assets. Goodwill represents the excess of the cost of the acquired business over the fair value of identifiable assets acquired. Goodwill is not amortized, but is subject to impairment testing annually or more often when events or circumstances indicate that it is more likely than not it is impaired. We amortize the cost of other acquired intangible assets over their estimated useful lives on a straight-line basis. Amortizable intangible assets are tested for impairment based on undiscounted cash flows and, if impaired, written down to fair value based on discounted cash flows. Goodwill and other acquired intangible assets are included in Lease receivables and other assets on our Consolidated Balance Sheets.
Other Comprehensive Income (Loss): We report gains and losses associated with changes in the fair value of derivatives designated as cash flow hedges and unrealized gains and losses on marketable securities classified as "available-for-sale" in comprehensive income or loss.
Guarantees: In limited cases, we have previously contracted to provide aircraft asset value guarantees to financial institutions and other third parties for a fee. We recognize the guarantee fee paid to us in Accrued interest and other payables on our Consolidated Balance Sheets. The fee received is amortized into Flight equipment marketing and gain on aircraft sales in our Consolidated Statements of Operations over the guarantee period. When it becomes probable that we will be required to perform under a guarantee, we cease recognition of the guarantee fee income and accrue a liability based on an estimate of the loss we will incur to perform under the guarantee. The provision for losses on aircraft asset value guarantees represents changes made in the current period based on our estimate of the losses on asset value guarantees that are probable of being exercised. We reverse the liability only when it is no longer probable that we will incur a loss.
Fair Value Measurements: Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We measure the fair value of our derivatives on a recurring basis and measure the fair values of aircraft, investment in finance and sales-type leases and asset value guarantees on a non-recurring basis.
Income Taxes: ILFC is included in the consolidated federal income tax return of AIG as well as certain state tax returns where AIG files on a combined/unitary basis. Our provision for federal income taxes is calculated on a separate return basis, adjusted to give recognition to the effects of net operating losses, foreign tax credits and other tax benefits to the extent we estimate that they would be realizable in AIG's consolidated federal income tax return. Under our tax sharing agreement with AIG, we settle our current tax liability as if ILFC and its subsidiaries are each a separate standalone taxpayer. Thus, AIG credits us to the extent our net operating losses, foreign tax credits and other tax benefits (calculated on a separate return basis) are used in AIG's consolidated tax return and charges us to the extent of our tax liability (calculated on a separate return basis). To the extent the benefit of a net operating loss is not utilized in AIG's consolidated federal income tax return, AIG reimburses us upon the expiration of the loss carry-forward period as long as we are still included in AIG's consolidated federal income tax return and the benefit would have been utilized if we had filed a separate consolidated federal income tax return. Our provision for state income taxes includes California, in which we file with AIG using the unitary apportionment factors, and certain other states, in which we file separate tax returns.
We calculate our provision for income taxes using the asset and liability method. This method considers the future tax consequences of temporary differences between the financial reporting and the tax basis of assets and liabilities measured using currently enacted tax rates. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
We recognize an uncertain tax benefit only to the extent that it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position.
Share-based Compensation: We participate in AIG's share-based payment and liability award programs and our share of the calculated costs is allocated to us by AIG. Compensation expense is recognized over the period during which an employee is required to provide service in exchange for the share-based payment.
Recent Accounting Guidance
Accounting Standard Adopted during 2014:
Presentation of Unrecognized Tax Benefits
In July 2013, the FASB issued an accounting standard that requires a liability related to unrecognized tax benefits to be presented as a reduction to the related deferred tax asset for a net operating loss carryforward or a tax credit carryforward (the "Carryforwards"). When the Carryforwards are not available at the reporting date under the tax law of the jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit will be presented in the financial statements as a liability and will not be combined with the related deferred tax assets. This standard is effective for fiscal years and interim periods beginning after December 15, 2013. Upon adoption, the standard must be applied prospectively to unrecognized tax benefits that exist at the effective date. Predecessor adopted the standard prospectively on January 1, 2014 and reclassed Current income taxes and other tax liabilities of $127.4 million to Deferred income taxes as a result of the adoption.
Future Application of Accounting Guidance:
Reporting Discontinued Operations
In April 2014, the FASB issued an accounting standard that changes the requirements for presenting a component or group of components of an entity as a discontinued operation and requires new disclosures. Under the standard, the disposal of a component or group of components of an entity should be reported as a discontinued operation if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results. Disposals of equity method investments, or those reported as held-for-sale, will be eligible for presentation as a discontinued operation if they meet the new definition. The standard also requires entities to provide specified disclosures about a disposal of an individually significant component of an entity that does not qualify for discontinued operations presentation.
The standard is effective prospectively for all disposals of components (or classification of components as held for sale) of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods beginning on or after December 15, 2015. Early adoption is permitted, but only for disposals (or classifications of components as held for sale) that have not been reported in financial statements previously issued. We adopted the standard on January 1, 2015, and it did not have a material effect on our consolidated financial condition, results of operations or cash flows.
Revenue from Contracts with Customers
In May 2014, the FASB issued an accounting standard that provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The standard will require an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This update creates a five-step model that requires entities to exercise judgment when considering the terms of the contract(s) which include (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue when each performance obligation is satisfied.
This standard is effective for nonpublic entities for annual periods beginning after December 15, 2017 and interim periods beginning after December 15, 2018. Nonpublic entities are permitted to adopt for annual and interim periods beginning after December 15, 2016. We have the option to apply the provisions of the standard either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of applying this standard recognized at the date of initial application. We plan to early adopt the standard on January 1, 2017. We are evaluating the effect the adoption of the standard will have on our consolidated financial statements.
Disclosure of Going Concern Uncertainties
In August 2014, the FASB issued an accounting standard that requires management to assess an entity's ability to continue as a going concern, and to provide related footnote disclosure in certain circumstances. The new standard will be effective for all entities in the first annual period ending after December 15, 2016. Earlier adoption is permitted. We plan to adopt the standard on January 1, 2017.
Consolidation: Amendments to the Consolidation Analysis
In February 2015, the FASB issued an accounting standard that affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. Specifically, the amendments modify the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities; eliminate the presumption that a general partner should consolidate a limited partnership; affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds.
This standard will be effective for annual periods beginning after December 15, 2016 and for interim periods beginning after December 15, 2017 for nonpublic entities. Early adoption is permitted, including adoption in an interim period. The standard may be applied retrospectively or through a cumulative effect adjustment to equity as of the beginning of the year of adoption. We plan to adopt the standard on January 1, 2017. We are evaluating the effect the adoption of the standard will have on our consolidated financial condition, results of operations and cash flows.

AerCap Transaction	12 Months Ended
AerCap Transaction	Dec. 31, 2014
AerCap Transaction
AerCap Transaction	3. AerCap Transaction
	On May 14, 2014, AerCap and AerCap Ireland Limited, a wholly-owned subsidiary of AerCap, completed the purchase of 100 percent of ILFC's common stock from AIG. The total consideration paid to AIG on the Closing Date consisted of $2.4 billion in cash and 97,560,976 newly-issued AerCap common shares. Prior to the consummation of the AerCap Transaction, ILFC paid a special distribution to AIG in the amount of $600.0 million.
	The total consideration paid to AIG, excluding the special distribution of $600.0 million paid by ILFC to AIG on May 13, 2014, had a value of approximately $7.0 billion based on AerCap's closing price per share of $46.59 on May 14, 2014. On the Closing Date, immediately after completing the AerCap Transaction, all of ILFC's assets were transferred substantially as an entirety to, and substantially all of ILFC's liabilities were assumed by, AerCap Trust.
	In connection with the AerCap Transaction, AerCap Trust and AerCap Ireland Capital Limited, issued $2.6 billion aggregate principal amount of senior notes (the "Acquisition Notes"), consisting of three tranches of notes in varying tenor in a private placement, of which $2.4 billion was used to satisfy the cash consideration of the AerCap Transaction, and the remaining proceeds were used for expenses related to the AerCap Transaction and general corporate purposes. The Acquisition Notes are fully and unconditionally guaranteed on a senior unsecured basis by AerCap and certain of its subsidiaries, including ILFC. Additionally, in December 2013, AerCap Ireland Capital Limited entered into a credit agreement for a senior unsecured revolving credit facility with AIG. The revolving credit facility provides for an aggregate commitment of $1.0 billion and may be used for AerCap's general corporate purposes. AerCap Trust and ILFC are unconditional guarantors of the facility.
	On May 13, 2014 ILFC had $22.7 billion of indebtedness outstanding, primarily consisting of senior unsecured bonds, senior secured bonds, export credit facilities, secured term loans and commercial bank debt. In connection with the Reorganization described in Note 1—Basis of Preparation, under the amendments to ILFC's debt agreements, AerCap Trust assumed these obligations, and AerCap and certain of its subsidiaries guaranteed such obligations. Accordingly, AerCap Trust, by the terms of the indentures governing ILFC's secured and unsecured bonds, became the successor obligor under ILFC's indentures, including the bonds issued under ILFC's shelf registration statements filed with the SEC. ILFC also agreed to continue to be an obligor under these debt agreements, including the indentures.
	As a result of the AerCap Transaction, AIG owns approximately 46 percent of AerCap. A portion of the AIG shares remain subject to a lockup agreement providing for the staggered expiration of lockup periods beginning nine months and ending 15 months after the Closing Date. To date, no shares have been sold by AIG. AIG has entered into agreements with AerCap regarding voting restrictions, standstill provisions and certain registration rights.
	The consideration transferred to effect the AerCap Transaction consisted of the following:

			(In thousands except share
			and per share amounts)
	Cash consideration		$	2,400,000	(a)
	97,560,976 AerCap common shares issued multiplied by AerCap closing share price per share of $46.59 on May 14, 2014			4,545,366
	Stock compensation			12,275

	Consideration transferred		$	6,957,641




	(a)	Excludes the $600.0 million special distribution paid by ILFC to AIG prior to the Closing Date.
	The following is a summary of the preliminary and final allocation of the purchase price to the estimated fair values of the identifiable assets acquired, the liabilities assumed and non-controlling interest at the Closing Date. There were several measurement period adjustments recognized subsequent to the amounts initially recognized and reported. These measurement period adjustments were primarily the result of completing the fair value calculations of Maintenance right intangible assets and Accrued maintenance liabilities at a component level. The measurement period adjustments presented below were retrospectively recognized as adjustments to our May 14, 2014 opening Balance Sheet, and the second and third quarter 2014 Statements of Operations. The opening Balance Sheet has been adjusted to reflect these changes as provided below.
	As of December 31, 2014, we had finalized all known measurement period adjustments.

	(a)	These adjustments impacted the Successor's previously reported consolidated interim financial statements. See Note 30—Quarterly Financial Information (Unaudited).
	(b)	Includes $0.8 billion of Restricted Cash.
	(c)	Includes $4.0 billion maintenance rights intangible, and the remaining amount relates to lease premium.
	AerCap Trust reported Transaction and integration related expenses related to the AerCap Transaction of $47.0 million for the period beginning February 5, 2014 and ending December 31, 2014. Those expenses are included in the Successor's Consolidated Statements of Operations and consist primarily of severance and other compensation expenses.
	The acquired business contributed Total revenues and other income of $2,623.4 million and Net income of $687.8 million to AerCap Trust for the period beginning February 5, 2014 and ending December 31, 2014.
	The following unaudited pro forma summary presents consolidated information of AerCap Trust as if the AerCap Transaction had been consummated on January 1, 2013:

	(Dollars in thousands)		Pro Forma			Pro Forma
			Year Ended			Year Ended
			December 31,			December 31,
			2014			2013
	Total revenue and other income		$	4,244,704		$	4,394,515
	Net income (loss)			749,498			(263,994	)
	The most significant pro forma adjustments were to reflect the (net of tax) impact of: (i) the amortization of intangible lease premium component as an adjustment to revenue; (ii) the expensing of the maintenance rights intangible, which occurs when the lease ends for EOL contracts or when the lessee provides us with an invoice for reimbursement relating to the cost of a qualifying maintenance event that relates to pre-acquisition usage for MR contracts. The related pro forma adjustment was based on the estimated annual charge in the first full year after the acquisition; (iii) the depreciation and amortization expenses related to the fair value adjustments to aircraft and other intangibles; (iv) the interest expense on the existing debt taking into account the fair value adjustment to the debt as of the Closing Date; (v) the interest expense related to the acquisition financing, as if the financing occurred as of January 1, 2013; (vi) other interest expense adjustments relating to the maintenance and security deposit liabilities as well as the prepayments on flight equipment; and (vii) non-recurring transaction and integration related expenses, as if they had been incurred as of January 1, 2013 instead of 2014.
	The above unaudited pro forma financial information is for informational purposes only and may not necessarily reflect the actual results of operations had the AerCap Transaction been consummated on January 1, 2013. The pro forma information did not adjust for gain from sales, impairment charges and loss from early extinguishment of debt. These pro forma amounts are not designed to represent the future expected financial results of either AerCap Trust or AerCap.
	Application of the Acquisition Method of Accounting:
	We applied the acquisition method of accounting and measured the identifiable assets acquired, the liabilities assumed, and non-controlling interest at fair value on the Closing Date. These fair values were determined using the market and income approaches and were primarily based on inputs and assumptions that are not observable in the market, other than certain debt financing arrangements assumed in the AerCap Transaction. The fair value measurement of each major asset acquired and liability assumed is discussed separately below:
	Flight equipment: We determined the fair value of our Flight equipment as of the Closing Date using an income approach based on the present value of the expected future cash flows.
We measured the fair value of our Flight equipment as if unencumbered by any existing contractual lease terms and based on the estimated physical maintenance condition as of the Closing Date. The expected cash flows were estimated using current market lease rates for the remainder of the terms of the existing leases and future market lease rates for additional leases and an estimated residual value based on the aircraft type, age, and airframe and engine configuration of the aircraft. The aggregate cash flows were then discounted to present value. The discount rates were based on the type and age of aircraft (including the remaining useful life of the aircraft), and incorporated market participant assumptions regarding the likely debt and equity financing components and the required returns of those financing components. Key inputs and assumptions underlying the income approach and the projected cash flows were contracted leases, lease extensions and new lease assumptions, residual values and appropriate discount rates and are discussed further below:
(a)The contracted leases were adjusted to current market rents as appropriate, and accounted for approximately 50% of the flight equipment's fair value.
(b)For in-production, younger aircraft, residual values were assumed after the extension of the existing lease or new lease. The residual value assumption was based on inputs from third party appraisers. The residual values accounted for approximately 30% of the flight equipment's fair value.
(c)For most aircraft, an extension of the existing lease or a new lease was assumed based on our knowledge of the lessee's fleet plans and expected market lease rents. The extensions or new leases accounted for approximately 15% of the flight equipment's fair value.
(d)Out-of-production, older aircraft residual values that were at the end of their economic life, were assumed to be sold for parts at the conclusion of their respective leases. The residual value assumptions for sales of parts were based on market data and inputs from AeroTurbine, our wholly-owned subsidiary that specializes in sales of aircraft parts. Sales of parts residual values accounted for approximately 5% of the flight equipment's fair value.
(e)The discount rate assumptions are based on our knowledge of market returns and leverage, which vary depending on the type and age of the aircraft, and range between 6% and 10%. The average discount rate, weighted by the fair value of ILFC's fleet, was approximately 7%.
Forward order book: The fair value of the forward order book, which is included in Prepayments on flight equipment on the Successor's Consolidated Balance Sheet, was estimated based on the present value of the cash flows expected to be generated by the asset. Under this approach, fair value was determined by discounting the difference between the estimated fair value, as indicated by third party aircraft appraiser forward base values, and the contractual purchase prices for each forward order aircraft, at the respective future delivery dates. The difference was discounted at a required market rate of return that reflects the relative risk of achieving the asset's expected cash flows and the time value of money.
Prepayments on flight equipment at the Closing Date included the fair value of the forward order book of ILFC of 317 aircraft, many of which were placed at favorable prices compared to the current market. The positions that were subject to a fair value adjustment relate to contracts for 64 Boeing 787 aircraft, 27 Boeing 737-800 aircraft, 206 Airbus A320 series aircraft (models A320neo, A321neo, A321-200), and 20 Airbus A350-900 aircraft. We determined that the remainder of our forward order book was at market terms and therefore no fair value adjustment was recorded for these positions.
Maintenance rights intangible asset and lease premium, net: The fair value of the maintenance rights intangible assets associated with EOL contracts was determined based on the present value of the expected cash flows, measured as the difference between the aircraft physical maintenance condition at the Closing Date and the specified contractual return condition at the end of the respective lease term adjusted for the credit risk of the lessee. The fair value of the maintenance rights intangible assets associated with MR contracts was determined based on the present value of reimbursements to lessees for maintenance events relating to pre-acquisition usage expected during the remaining post-acquisition lease term. The expected cash flows of the EOL and MR contracts are discounted at a required market rate of return that reflects the relative risk of achieving the expected cash flows of the assets and the time value of money.
The fair value of the lease premium was determined based on the present value of the expected cash flows calculated as the difference between the contractual lease payments, adjusted for the credit risk of the lessee, and the lease payments that the aircraft could generate over the remaining lease term based on current market rates.
Other intangible assets: Primarily includes customer relationship intangible assets and other intangible assets. The fair value of the customer relationship intangible assets was determined using the excess earnings method. This method measures the value of an intangible asset by calculating the residual profit after subtracting the appropriate returns for all other complementary assets that benefit the business.
Accrued maintenance liability: Under our aircraft leases, the lessee is responsible for all operating expenses during the term of the lease, as well as for normal maintenance and repairs and major aircraft component maintenance events. Under the provisions of many of our leases, the lessee is required to make payments of supplemental maintenance rentals based on hours or cycles of utilization. If a lessee pays supplemental maintenance rentals, we are generally obligated to reimburse the lessee for costs they incur for certain qualified maintenance events. In connection with a lease of a used aircraft, we generally agree to contribute to certain maintenance events that the lessee incurs during the lease term (Lessor Contributions).
We determined the fair value of our maintenance liability relating to pre-acquisition usage based on the present value of expected cash outflows during the remaining lease term consisting of (i) expected reimbursements of supplemental maintenance rentals at the time of the forecasted maintenance event; and (ii) expected Lessor Contributions at the time of the forecasted maintenance event. These two cash flows were discounted to their respective present values using a market rate of return that reflects the relative risk of the cash flows and the time value of money.
Debt: The fair value of debt was estimated using quoted market prices where available. The fair value of certain debt without quoted market prices is estimated using discounted cash flow analyses based on current market prices for similar type debt instruments.
Non-controlling interests ("NCI"): NCI consists of Market Auction Preferred Stock ("MAPS") securities issued by ILFC. The MAPS are not convertible, and have a liquidation value of $100,000 per share, with 500 shares issued and outstanding for each of the MAPS Series A and B securities. The dividend rate, other than the initial rate, for each dividend period for each series is to be reset approximately every seven weeks (49 days) on the basis of orders placed in an auction, provided such auctions are able to occur. MAPS fair values were estimated using discounted cash flow analysis based on estimated market yield for similar instruments.
Income taxes: AerCap and AIG made an election under Section 338(h)(10) of the IRS code, which resulted in the AerCap Transaction being treated as a sale of the assets of ILFC and its subsidiaries for U.S. federal and state income tax purposes, except for our wholly-owned subsidiary, AeroTurbine, which was treated as a taxable share purchase. As a result of this election, the tax adjusted purchase price was allocated to our net assets which changed the tax basis used to derive the deferred tax assets and liabilities. At the Closing Date, but prior to the Reorganization, we had a net deferred tax liability of $23.3 million, compared to the Predecessor's net deferred tax liability of $4.1 billion immediately preceding the Closing Date. Immediately after consummation of the AerCap Transaction, the plan of Reorganization was executed and ILFC immediately began transferring its assets and liabilities to AerCap Trust, the majority of whose earnings are subject to Irish tax. We transferred a mix of assets and liabilities with various book tax basis differences to Ireland from May 14, 2014 to December 31, 2014. The U.S. federal and state tax liabilities for tax years prior to the Closing Date, including the assumed liabilities related to unrecognized tax benefits, remain with AIG.

	Related Parties: As described in Note 1—Basis of Preparation, prior to May 14, 2014 ILFC was an indirect wholly-owned subsidiary of AIG. On May 14, 2014, AIG sold ILFC to AerCap and AerCap Ireland Limited, a wholly-owned subsidiary of AerCap. On the Closing Date, immediately after completing the AerCap Transaction, ILFC's assets were transferred substantially as an entirety to, and substantially all of ILFC's liabilities were assumed by AerCap Trust, a statutory trust formed on February 5, 2014.The purchase price consideration paid for ILFC included 97,560,976 shares of AerCap common stock. As a result, AIG holds a significant ownership interest in AerCap subsequent to the sale of ILFC. Consequently, AIG and its subsidiaries are considered related parties both before and after the Closing Date. AerCap and its consolidated subsidiaries, including AerCap Ireland Limited, and AerCap Ireland Capital Limited are related parties after the Closing Date.
	Predecessor
	Related Party Allocations and Fees: Prior to May 14, 2014, we were party to cost sharing agreements, including with respect to tax, with AIG. Generally, these agreements provided for the allocation of corporate costs based upon a proportional allocation of costs to all subsidiaries. Our management believed the proportionate method used to allocate corporate costs was reasonable. It was not practicable to determine what the amounts of those expenses would have been had we operated on a standalone basis. Previously, we also paid other subsidiaries of AIG a fee related to management services provided for certain of our foreign subsidiaries and we continue to earn management fees from two trusts consolidated by AIG for the management of aircraft we sold to the trusts in prior years, (the "Castle Trusts"). For the period preceding our sale by AIG to AerCap, we were included in the consolidated federal income tax return of AIG as well as certain state tax returns, where AIG files on a combined/unitary basis. Settlement with AIG for taxes was determined in accordance with the tax sharing agreement the we had with AIG up to the Closing Date. Prior to the Closing Date, under the agreement AIG entered into with AerCap, net tax payments under the tax sharing agreement were temporarily suspended, and the tax sharing agreement with AIG was terminated upon consummation of the AerCap Transaction. Our U.S. federal and state tax liabilities for tax years prior to May 14, 2014, including the liability related to unrecognized tax benefits, remain with AIG.
	Dividends and Capital Contribution: On May 13, 2014, ILFC paid a special distribution of $600.0 million to AIG, which ILFC was required to pay prior to the completion of the AerCap Transaction in accordance with the Share Purchase Agreement. The special distribution was recorded in Retained earnings as a dividend. During the period beginning January 1, 2014 and ending May 13, 2014, an additional $1.4 million was recorded in Retained earnings as a dividend, when we paid a fee to satisfy a statutory law requirement on behalf of AIG. Additionally, we recorded a decrease in Retained earnings of $5.3 million, net of tax of $2.9 million, to record a non-cash dividend reflecting the difference between the proceeds received and the net carrying value of a corporate aircraft sold to AIG. We recorded an increase to Retained earnings of $9.6 million for a receipt from AIG for certain expected separate company tax liabilities, as required under the AerCap sales agreement.
	Expenses Paid by AIG on Our Behalf: AIG did not pay any expenses on our behalf during the period beginning January 1, 2014 and ending May 13, 2014. We recorded $10.1 million and $2.6 million in Paid-in capital for the years ended December 31, 2013 and 2012, respectively, for compensation, legal fees and other expenses paid by AIG on our behalf for which we were not required to reimburse.
	Derivatives and Insurance Premiums: The counterparty of all of our interest rate swap agreements as of December 31, 2013, was AIG Markets, Inc., a wholly-owned subsidiary of AIG. See Note 26—Fair Value Measurements and Note 27—Derivative Financial Instruments. In addition, we purchased insurance through a broker who may have placed part of our policies with AIG. Total insurance premiums were $2.2 million, $8.2 million, and $9.9 million for the beginning January 1, 2014 and ending May 13, 2014, and the years ended December 31, 2013 and 2012, respectively.
	Successor
	Derivatives: The counterparty of all of our interest rate swap agreements as of December 31, 2014, was AIG Markets, Inc., a wholly-owned subsidiary of AIG, and these swap agreements are guaranteed by AIG. See Note 26—Fair Value Measurements and Note 27—Derivative Financial Instruments.
	Management Fees: We earn management fees from two trusts consolidated by AIG for the management of aircraft we sold to the trusts in prior years, (the "Castle Trusts").
	Dividends and Capital Contribution: During the period beginning February 5, 2014 and ending December 31, 2014, we recorded $14.9 million in stock compensation for AerCap share-based awards, as a capital contribution in Paid-in-capital.
	Transactions with AerCap: Subsequent to the AerCap Transaction, AerCap provides us with certain managerial, finance, technical, marketing and support services which are essential to our business operations. We compensate AerCap for these services based on an arms-length price and in accordance with AerCap's global transfer pricing methodology. We had a net receivable from AerCap of $1,345.2 million at December 31, 2014 relating to operational activities of group entities including, but not limited to, the issuance and payoff of third-party debt, the purchase and transfer of aircraft, management fees allocated by AerCap and other cash transfers in the ordinary course of business.
	Aircraft Leased to AerCap: Some of our aircraft are on lease to AerCap, which leases the aircraft to airlines. We recorded commission to AerCap Ireland Limited of $0.7 million for the period beginning February 5, 2014 and ending December 31, 2014, related to those leases.

Debt	13. Debt
	Successor
	As of December 31, 2014, the principal amount of our outstanding indebtedness, which excludes fair value adjustments of $1.3 billion, was approximately $23.3 billion and primarily consisted of senior unsecured, subordinated and senior secured notes, export credit facilities, commercial bank debt, and revolving credit debt. As a result of applying the acquisition method of accounting, we adjusted the carrying amounts of our debt to fair value and eliminated any deferred debt discounts and premiums as of the Closing Date. Any debt issue cost capitalized by the Predecessor was also eliminated as of the Closing Date. (See Note 3—AerCap Transaction). These fair value adjustments are being amortized over the life of each associated debt instrument using the effective interest method.
	The following table provides a summary of our indebtedness at December 31, 2014:

The proceeds from the $800 million notes were advanced to AerCap Ireland Capital Limited and were used for general corporate purposes, including for AerCap Trust.
	(c)	As a result of applying the acquisition method of accounting, we adjusted the carrying amount of our debt to fair value as of the Closing Date. See Note 3—AerCap Transaction.

	2014 Successor Debt Issuances
	On May 14, 2014, AerCap Trust and AerCap Ireland Capital Limited co-issued $2.6 billion senior unsecured notes. Substantially all of the proceeds from the offering, net of offering costs, were used to finance the AerCap Transaction. On September 29, 2014, AerCap Trust and AerCap Ireland Capital Limited co-issued $800 million senior notes by a supplemental indenture to the May offering. The proceeds from the $800 million notes were advanced to AerCap Ireland Capital Limited and were used for general corporate purposes, including for AerCap Trust.
	Collateral Pledged for Secured Debt
	As of December 31, 2014, we had pledged as collateral 464 aircraft with an aggregate net book value of $11.8 billion. As of December 31, 2014, the outstanding balance before fair value adjustments on the secured debt was $7.6 billion, including the AeroTurbine revolving credit facility of $302.1 million. AeroTurbine's assets and the associated book value serves as collateral for the AeroTurbine revolving credit facility.
	Amendments to our Debt Agreements with Respect to the AerCap Transaction and Reorganization
	In connection with the Reorganization described in Note1—Basis of Preparation, ILFC entered into amendments to certain of its debt agreements in order to reflect the Reorganization. Under the amendments to ILFC's debt agreements for the 2004 Airbus ECA Facility, 2012 Ex-Im Capital Markets Facility, Hyperion facility, Vancouver facility, Temescal facility, Camden facility, AeroTurbine revolving credit facility, $2.3 billion revolving credit facility, AerCap Trust assumed these obligations and performance of certain covenants to be performed or observed by ILFC, and AerCap and certain of its subsidiaries guaranteed such obligations and the performance of certain covenants to be performed or observed by ILFC. Accordingly, AerCap Trust, by the terms of the indentures governing ILFC's secured and unsecured bonds, became the successor obligor under ILFC's indentures, including the bonds issued under ILFC's shelf registration statements filed with the SEC. As a result, AerCap Trust assumed ILFC's reporting obligations. ILFC also agreed to continue to be an obligor under these agreements, including the indentures.
	On March 11, 2014, AerCap Ireland Capital Limited entered into an agreement to replace ILFC's $2.3 billion revolving credit facility. The revolving credit facility became effective and the ILFC facility was terminated on the Closing Date.
Unsecured Notes
As of December 31, 2014, we had an aggregate outstanding principal amount of unsecured notes of approximately $14.6 billion.
ILFC Legacy Notes
As of December 31, 2014, we had an aggregate outstanding principal amount of senior unsecured notes of approximately $8.5 billion issued by ILFC pursuant to shelf registration statements prior to the AerCap Transaction ("ILFC Legacy Notes"). The ILFC Legacy Notes have maturities ranging through 2022. The fixed rate notes bear interest at rates ranging from 3.875% to 8.875%, and the floating rate notes bear interest at three-month LIBOR plus a margin of 1.95%, with the interest rate resetting quarterly. The notes are not subject to redemption prior to their stated maturity and there are no sinking fund requirements.
The indentures governing the ILFC Legacy Notes contain customary covenants that, among other things, restrict our, and our restricted subsidiaries', ability to (i) incur liens on assets; (ii) declare or pay dividends or acquire or retire shares of our capital share during certain events of default; (iii) designate restricted subsidiaries as non-restricted subsidiaries or designate non-restricted subsidiaries; (iv) make investments in or transfer assets to non-restricted subsidiaries; and (v) consolidate, merge, sell, or otherwise dispose of all or substantially all of our assets. The indentures also provide for customary events of default, including, but not limited to, the failure to pay scheduled principal and interest payments on the notes, the failure to comply with covenants and agreements specified in the indenture, the acceleration of certain other indebtedness resulting from non-payment of that indebtedness and certain events of insolvency. If any event of default occurs, any amount then outstanding under the indentures may immediately become due and payable.
Upon consummation of the AerCap Transaction, AerCap Trust became the successor issuer under the ILFC Legacy Notes indentures. ILFC also agreed to continue to be co-obligor. In addition, AerCap and certain of its subsidiaries became guarantors of the notes.
AerCap Trust & AerCap Ireland Capital Limited Senior Unsecured Notes
In May 2014, AerCap Trust and AerCap Ireland Capital Limited, co-issued $2.6 billion aggregate principal amount of senior unsecured notes, consisting of $400.0 million of 2.75% notes due 2017, $1.1 billion of 3.75% notes due 2019, and $1.1 billion of 4.50% notes due 2021 (collectively the "Acquisition Notes"). The proceeds from the offering were primarily used to finance the cash consideration paid in connection with the AerCap Transaction.
In September 2014, AerCap Trust and AerCap Ireland Capital Limited, co-issued $800.0 million aggregate principal amount of 5.00% senior notes (the "5.00% Notes," and together with the Acquisition Notes, the "AGAT/AICL Notes"). The proceeds from the offering were advanced to AerCap Ireland Capital Limited and were used for general corporate purposes. The final maturity date of the 5.00% Notes will be October 1, 2021.
The AGAT/AICL Notes are guaranteed by AerCap and certain of its subsidiaries. The AGAT/AICL Notes are not subject to redemption prior to their stated maturity and there are no sinking fund requirements.
The indenture governing the AGAT/AICL Notes contains customary covenants that, among other things, restrict our, and our restricted subsidiaries', ability to (i) incur liens on assets; (ii) declare or pay dividends or acquire or retire shares of our capital share during certain events of default; (iii) designate restricted subsidiaries as non-restricted subsidiaries or designate non-restricted subsidiaries; (iv) make investments in or transfer assets to non-restricted subsidiaries; and (v) consolidate, merge, sell, or otherwise dispose of all or substantially all of our assets. The indenture also provides for customary events of default, including, but not limited to, the failure to pay scheduled principal and interest payments on the notes, the failure to comply with covenants and agreements specified in the indenture, the acceleration of certain other indebtedness resulting from non-payment of that indebtedness and certain events of insolvency. If any event of default occurs, any amount then outstanding under the indenture may immediately become due and payable.
Redemption of Unsecured Notes: We may redeem each series of our unsecured notes, in whole or in part, at any time at a price equal to 100% of the aggregate principal amount plus the applicable "make-whole" premium plus accrued and unpaid interest, if any, to the redemption date. The "make-whole" premium is the excess of:
-1	the sum of the present value at such redemption date of all remaining scheduled payments of principal and interest on such note through the stated maturity date of the notes (excluding accrued but unpaid interest to the redemption date), discounted to the date of redemption using a discount rate equal to the Treasury Rate plus 50 basis points; over
-2	the principal amount of the notes to be redeemed.
Export Credit Facilities
2004 Airbus ECA Facility
In 1999 and 2004, ILFC entered into ECA facility agreements through certain wholly-owned subsidiaries. The 1999 and 2004 ECA facilities were used to fund purchases of certain Airbus family aircraft through 2001 and 2010, respectively. Each aircraft purchased was financed by a ten-year fully amortizing loan. New financings are no longer available under either ECA facility. The obligations of the subsidiary borrower were originally guaranteed by ILFC, and upon consummation of the AerCap Transaction, AerCap and certain of its subsidiaries were added as additional guarantors.
As of December 31, 2014, approximately $1.04 billion was outstanding under the 2004 ECA facility and no loans were outstanding under the 1999 ECA facility.
In February 2015, we entered into an amendment to the 2004 ECA facility allowing funds that previously were required to be segregated to be replaced by letters of credit, and releasing the security interest in respect of certain aircraft for which the associated loans had been repaid. Prior to entering into this amendment, we were required to segregate security deposits and overhaul rentals received under the leases related to the aircraft funded under the facility to the extent amounts remained outstanding under the relevant aircraft loan. The segregated funds were deposited into separate accounts pledged to and controlled by the security trustee of the 2004 ECA facility.
We must register mortgages on certain aircraft funded under the 2004 ECA facility in the local jurisdictions in which the respective aircraft are registered. The mortgages are required to be filed only with respect to aircraft that have outstanding loan balances.
2012 Ex-Im Capital Markets Facility
On December 19, 2012, ILFC issued through a consolidated entity pre-funded amortizing notes with an aggregate principal amount of $287.0 million. The notes mature in January 2025 and scheduled principal payments commenced in April 2013. The notes bear interest at a rate per annum equal to 1.492%. During the year ended December 31, 2013, ILFC used the proceeds from the notes to finance two Boeing 777-300ER aircraft, which serve as collateral for the notes. Upon consummation of the AerCap Transaction, AerCap and certain of its other subsidiaries guaranteed the Ex-Im financings. The Ex-Im financings are also guaranteed by the Export-Import Bank of the United States.
Senior Secured Notes
In August 2010, ILFC issued $3.9 billion of senior secured notes (the "Senior Secured Notes"), with $1.35 billion that matured in September 2014 and bore interest of 6.5%, $1.275 billion maturing in September 2016 and bearing interest of 6.75%, and $1.275 billion maturing in September 2018 and bearing interest of 7.125%. Upon consummation of the AerCap Transaction, AerCap Trust became the successor issuer under the indenture governing the Senior Secured Notes. ILFC also agreed to continue to be a co-obligor. In addition, AerCap and certain of its other subsidiaries became guarantors of the Senior Secured Notes. We can redeem the Senior Secured Notes at any time prior to their maturity, subject to a penalty of the greater of 1% of the outstanding principal amount and a "make-whole" premium. There is no sinking fund for the Senior Secured Notes.
The Senior Secured Notes are secured by a designated pool of aircraft, initially consisting of 174 aircraft and cash collateral when required. In addition, two of our subsidiaries, which either own or hold leases attached to the aircraft included in the pool securing the Senior Secured Notes, have guaranteed the notes. Following repayment of the $1.35 billion on the 6.5% Senior Secured Notes due 2014, certain collateral was released, and as of December 31, 2014, 146 aircraft secured the notes.
The indenture and the aircraft mortgage and security agreement governing the Senior Secured Notes contain customary covenants that, among other things, restrict our and our restricted subsidiaries' ability to (i) create liens; (ii) sell, transfer or otherwise dispose of the assets serving as collateral for the Senior Secured Notes; (iii) declare or pay dividends or acquire or retire shares of our capital share during certain events of default; (iv) designate restricted subsidiaries as non-restricted subsidiaries or designate non-restricted subsidiaries; and (v) make investments in or transfer assets to non-restricted subsidiaries.
The indenture also restricts our and the subsidiary guarantors' ability to consolidate, merge, sell or otherwise dispose of all, or substantially all, of our assets. The indenture also provides for customary events of default, including but not limited to, the failure to pay scheduled principal and interest payments on the notes, the failure to comply with covenants and agreements specified in the indenture, the acceleration of certain other indebtedness resulting from non-payment of that indebtedness, and certain events of insolvency. If any event of default occurs, any amount then outstanding under the Senior Secured Notes may immediately become due and payable.
Institutional Secured Term Loans
Hyperion Facility
In March 2014, one of ILFC's indirect, wholly-owned subsidiaries entered into a secured term loan agreement in the amount of $1.5 billion. The loan bears interest at LIBOR plus a margin of 2.75% with a 0.75% LIBOR floor, or, if applicable, a base rate plus a margin of 1.75%. The loan matures in March 2021. We can voluntarily prepay the loan at any time, subject to certain conditions.
The obligations of the subsidiary borrower were originally guaranteed by ILFC and certain of its subsidiaries, and upon consummation of the AerCap Transaction, AerCap and certain of its subsidiaries were added as additional guarantors.
The loan is secured by the equity interests in the borrower and certain SPE subsidiaries of the borrower. The SPEs hold title to 84 aircraft with an appraised value of approximately $2.28 billion as of December 31, 2014, representing a loan-to-value ratio of approximately 65.7%. The loan requires a loan-to-value ratio of no more than 70%. If the maximum loan-to-value ratio is exceeded, we will be required to prepay portions of the outstanding loans, deposit an amount in the cash collateral account or transfer additional aircraft to SPEs, subject to certain concentration criteria, so that the ratio is equal to or less than 70%.
The loan contains customary covenants and events of default, including covenants that limit the ability of the subsidiary borrower and its subsidiaries to incur additional indebtedness and create liens, and covenants that limit the ability of the guarantors, the subsidiary borrower and its subsidiaries to consolidate, merge or dispose of all or substantially all of their assets and enter into transactions with affiliates.
Vancouver Facility
In February 2012, one of ILFC's indirect, wholly-owned subsidiaries entered into a secured term loan agreement in the amount of $900.0 million. In April 2013, ILFC amended the agreement and simultaneously prepaid $150.0 million of the outstanding principal amount. The remaining outstanding principal amount of $750.0 million bears interest at an annual rate of LIBOR plus 2.75%, with a LIBOR floor of 0.75%, or, if applicable, a base rate plus a margin of 1.75%. The loan initially bore interest at LIBOR plus a margin of 4.0% with a 1.0% LIBOR floor, or, if applicable, a base rate plus a margin of 3.0%. The loan matures in June 2017. We can voluntarily prepay the loan at any time, subject to certain conditions.
The obligations of the subsidiary borrower were originally guaranteed by ILFC and certain of its subsidiaries, and upon consummation of the AerCap Transaction, AerCap and certain of its subsidiaries were added as additional guarantors.
The loan is secured by the equity interests in certain SPEs of the subsidiary borrower. The SPEs initially held title to 62 aircraft with an appraised value of approximately $1.66 billion as of December 31, 2011, equaling an initial loan-to-value ratio of approximately 54%. After giving effect to the 2013 amendment, certain collateral that had served as security for the secured term loan was released. As of December 31, 2014, the SPEs collectively own a portfolio of 56 aircraft with an appraised value of approximately $1.23 billion, equaling a loan-to-value ratio of approximately 61.2%. The loan requires a loan-to-value ratio of no more than 63%. If the maximum loan-to-value ratio is exceeded, we will be required to prepay a portion of the outstanding loan, deposit an amount in the cash collateral account or transfer additional aircraft to SPEs, subject to certain concentration criteria, so that the ratio is equal to or less than 63%.
The loan contains customary covenants and events of default, including covenants that limit the ability of the subsidiary borrower and its subsidiaries to incur additional indebtedness and create liens, and covenants that limit the ability of the guarantors, the subsidiary borrower and its subsidiaries to consolidate, merge or dispose of all or substantially all of their assets and enter into transactions with affiliates.
Temescal Facility
In March 2011, one of ILFC's indirect, wholly-owned subsidiaries entered into a secured term loan agreement with lender commitments in the amount of approximately $1.3 billion, which was subsequently increased to approximately $1.5 billion. As of December 31, 2014, approximately $1.1 billion was outstanding. The loan bears interest at LIBOR plus a margin of 2.75%, or, if applicable, a base rate plus a margin of 1.75%. The loan matures in March 2018. We can voluntarily prepay the loan at any time, subject to certain conditions.
The obligations of the subsidiary borrower were originally guaranteed by ILFC and certain of its subsidiaries, and upon consummation of the AerCap Transaction, AerCap and certain of its subsidiaries were added as additional guarantors.
The loan is secured by a portfolio of 54 aircraft and the equity interests in certain SPEs that own the pledged aircraft. The 54 aircraft had an initial appraised value of approximately $2.4 billion, representing a loan-to-value ratio of approximately 65%. The subsidiary borrower is required to maintain compliance with a maximum loan-to-value ratio, which declines over time, as set forth in the term loan agreement. If the maximum loan-to-value ratio is exceeded, we will be required to prepay portions of the outstanding loans, deposit an amount in the cash collateral account or transfer additional aircraft to the SPEs, subject to certain concentration criteria, so that the ratio is equal to or less than the maximum loan-to-value ratio.
The loan facility contains customary covenants and events of default, including covenants that limit the ability of the subsidiary borrower and its subsidiaries to incur additional indebtedness and create liens, and covenants that limit the ability of the guarantors, the subsidiary borrower and its subsidiaries to consolidate, merge or dispose of all or substantially all of their assets and enter into transactions with affiliates.
AeroTurbine Revolving Credit Agreement
In November 2014, AeroTurbine entered into an amended and restated credit facility providing for a maximum aggregate available amount of $550.0 million, subject to availability determined by a calculation utilizing AeroTurbine's aircraft assets and accounts receivable. As of December 31, 2014, AeroTurbine had approximately $302.1 million outstanding under the facility. Borrowings under the facility bear interest determined, with certain exceptions, based on LIBOR plus a margin of 2.5%. The facility will expire in November 2019.
AeroTurbine's obligations under the facility are guaranteed by AerCap and certain of its subsidiaries, including AeroTurbine's subsidiaries (subject to certain exclusions). AeroTurbine's obligations are secured by substantially all of the assets of AeroTurbine and its subsidiary guarantors.
The credit agreement contains customary events of default and covenants, including certain financial covenants. Additionally, the credit agreement imposes limitations on AeroTurbine's ability to pay dividends to us (other than dividends payable solely in common share).
Camden Facility
In March 2012, one of ILFC's indirect, wholly-owned subsidiaries entered into a $203 million term loan facility that was used to finance seven Boeing 737-800s. The principal of each senior loan issued under the facility will partially amortize over six years, with the remaining principal payable at the maturity date. At December 31, 2014, approximately $155.2 million was outstanding and the average interest rate on the loans was 4.73%. The loans are non-recourse to ILFC except under limited circumstances and are secured by the purchased aircraft and lease receivables. The subsidiary borrower can voluntarily prepay the loans at any time subject to a 1% prepayment fee prior to March 30, 2015. In March 2013, ILFC amended certain financial covenants under this term loan facility. The subsidiary borrower under the term loan facility is prohibited from: incurring additional debt; incurring additional capital expenditures; hiring employees; and negatively pledging the assets securing the facility. Upon consummation of the AerCap Transaction, AerCap and certain of its subsidiaries guaranteed certain obligations under the term loan.
Subordinated Debt
ECAPS Subordinated Notes
In December 2005, ILFC issued two tranches of subordinated notes in an aggregate principal amount of $1.0 billion. The $400.0 million tranche has a call option date of December 21, 2015 and has a fixed interest rate of 6.25% until the 2015 call option date. If we do not exercise the call option, the interest rate will change to a floating rate, reset quarterly, based on a margin of 1.80% plus the highest of three-month LIBOR, 10-year constant maturity treasury, and 30-year constant maturity treasury. We can call the $600.0 million tranche at any time. The interest rate on the $600.0 million tranche is a floating rate with a margin of 1.55% plus the highest of three-month LIBOR, 10-year constant maturity treasury, and 30-year constant maturity treasury. The interest rate resets quarterly. As of December 31, 2014, the interest rate was 4.37%.
In July 2013, ILFC amended the financial tests in both tranches of notes by changing the method of calculating the ratio of equity to total managed assets and the minimum fixed charge coverage ratio, making it less likely that we will fail to comply with such financial tests. Failure to comply with these financial tests will result in a "mandatory trigger event". If a mandatory trigger event occurs and we are unable to raise sufficient capital in a manner permitted by the terms of the subordinated debt to cover the next interest payment on the subordinated debt, a "mandatory deferral event" will occur, requiring us to defer all interest payments and prohibiting the payment of cash dividends on AerCap Trust or ILFC's capital share or its equivalent until both financial tests are met or we have raised sufficient capital to pay all accumulated and unpaid interest on the subordinated debt. Mandatory trigger events and mandatory deferral events are not events of default under the indenture governing the subordinated debt.
Upon consummation of the AerCap Transaction, the notes were assumed by AerCap Trust, and AerCap and certain of its subsidiaries became guarantors. ILFC remains a co-obligor under the indentures governing the notes.
Unsecured Revolving Credit Facilities
Citi Revolving Credit Facility
In March 2014, AerCap Ireland Capital Limited entered into a $2.75 billion four-year senior unsecured revolving credit facility (the "Citi Revolver"), which became effective upon the closing of the AerCap Transaction. The facility has an accordion feature option permitting increases to a maximum size of $4.0 billion. The facility matures in May 2018. The Citi Revolver replaced the $2.3 billion three-year senior unsecured revolving credit facility entered into by ILFC in October 2012, which was simultaneously terminated. The obligations under the Citi Revolver are guaranteed by AerCap and certain of its subsidiaries, including AerCap Trust and ILFC.
In September 2014, AerCap Ireland Capital Limited increased the size of the facility to $2.925 billion and in October 2014, AerCap Ireland Capital Limited further increased the size of the facility to $2.955 billion.
As of December 31, 2014, the facility was undrawn.
AIG Revolving Credit Facility
In December 2013, AerCap Ireland Capital Limited entered into a $1.0 billion five-year senior unsecured revolving credit facility (the "AIG Revolver"), with AIG as lender and administrative agent, which became effective upon the consummation of the AerCap Transaction. The facility matures on May 14, 2019. The obligations under the AIG Revolver are guaranteed by AerCap and certain of its subsidiaries, including AerCap Trust and ILFC.
As of December 31, 2014, there were no loans outstanding under the facility.
Loss on Extinguishment of Debt
2013. During the year ended December 31, 2013, we prepaid in full our $550 million secured term loan originally scheduled to mature in April 2016, the total outstanding under both tranches of the $106.0 million secured financing, and the total outstanding under the $55.4 million secured financing, and prepaid $150 million of the outstanding principal amount of our secured term loan due June 30, 2017. In connection with these prepayments, we recognized charges aggregating $17.7 million from the write off of unamortized deferred financing costs and deferred debt discount.
2012. During the year ended December 31, 2012, we prepaid the remaining $456.9 million outstanding under our secured credit facility dated October 13, 2006. We also prepaid in full our $750 million secured term loan and we refinanced our $550 million secured term loan at a lower interest rate. In connection with these prepayments and refinancing, we recognized charges aggregating $22.9 million from the write off of unamortized deferred financing costs and deferred debt discount.
Other
Under the terms of our subordinated debt, we may be restricted from paying cash dividends on our capital stock in the future if we fail to comply with certain covenants, as described above under "—ECAPS Subordinated Notes."

(a)	Of these amounts, $173.5 million (2013) was non-recourse to ILFC. These secured financings were incurred by VIEs, and consolidated into Predecessor consolidated financial statements.
(b)	During the year ended December 31, 2013, Predecessor recorded a $19.5 million adjustment to correct and fully align amortization of deferred debt issue costs and debt discounts in prior periods with the effective interest method, of which $4.4 million related to debt discounts and is reflected herein. See Note 1—Basis of Preparation.
For some of our secured debt financings, we created direct and indirect wholly-owned subsidiaries for the purpose of purchasing and holding title to aircraft, and we pledged the equity of those subsidiaries as collateral. These subsidiaries have been designated as non-restricted subsidiaries under our indentures and meet the definition of a VIE. We have determined that we are the PB of such VIEs and, accordingly, we consolidate such entities into Predecessor consolidated financial statements. See Note 25—Variable Interest Entities for more information on VIEs.

(a)	Amounts represent net book value and number of aircraft securing ILFC secured bank term debt and do not include the book value or number of AeroTurbine assets securing the AeroTurbine revolving credit agreement, under which $380.5 million is included in the total debt outstanding. ILFC guarantees the AeroTurbine revolving credit agreement on an unsecured basis.
Senior Secured Bonds
On August 20, 2010, we issued $3.9 billion of senior secured notes, with $1.35 billion maturing in September 2014 and bearing interest of 6.5%, $1.275 billion maturing in September 2016 and bearing interest of 6.75%, and $1.275 billion maturing in September 2018 and bearing interest of 7.125%. The notes are secured by a designated pool of aircraft, initially consisting of 174 aircraft, together with the attached leases and all related equipment, and cash collateral when required. In addition, two of our subsidiaries, which either own or hold leases attached to the aircraft included in the pool securing the notes, have guaranteed the notes. We can redeem the notes at any time prior to their maturity, provided we give notice between 30 to 60 days prior to the intended redemption date and subject to a penalty of the greater of 1% of the outstanding principal amount and a "make-whole" premium. There is no sinking fund for the notes.
The indenture and the aircraft mortgage and security agreement governing the senior secured notes contain customary covenants that, among other things, restrict our and our restricted subsidiaries' ability to: (i) create liens; (ii) sell, transfer or otherwise dispose of the assets serving as collateral for the senior secured notes; (iii) declare or pay dividends or acquire or retire shares of our capital stock during certain events of default; (iv) designate restricted subsidiaries as non-restricted subsidiaries or designate non-restricted subsidiaries and (v) make investments in or transfer assets to non-restricted subsidiaries. The indenture also restricts our and the subsidiary guarantors' ability to consolidate, merge, sell or otherwise dispose of all, or substantially all, of our assets.
The indenture provides for customary events of default, including but not limited to, the failure to pay scheduled principal and interest payments on the notes, the failure to comply with covenants and agreements specified in the indenture, the acceleration of certain other indebtedness resulting from non-payment of that indebtedness, and certain events of insolvency. If any event of default occurs, any amount then outstanding under the senior secured notes may immediately become due and payable.
ECA Financings
We entered into ECA facility agreements in 1999 and 2004 through certain direct and indirect wholly owned subsidiaries that have been designated as non-restricted subsidiaries under our indentures. The 1999 and 2004 ECA facilities were used to fund purchases of Airbus aircraft through 2001 and 2010, respectively. Each aircraft purchased was financed by a ten-year fully amortizing loan. New financings are no longer available to us under either ECA facility.
As of December 31, 2013, approximately $1.5 billion was outstanding under the 2004 ECA facility and no loans were outstanding under the 1999 ECA facility. The interest rates on the loans outstanding under the 2004 ECA facility are either fixed or based on LIBOR and ranged from 0.316% to 4.711% at December 31, 2013. The loans are guaranteed by various European ECAs. We have collateralized the debt with pledges of the shares of wholly owned subsidiaries that hold title to the aircraft financed under the facilities. The 2004 ECA facility contains customary events of default and restrictive covenants.
The 2004 ECA facility requires us to segregate security deposits, overhaul rentals and rental payments received under the leases related to the aircraft funded under the 2004 ECA facility (segregated rental payments are used to make scheduled principal and interest payments on the outstanding debt). The segregated funds are deposited into separate accounts pledged to and controlled by the security trustee of the 2004 ECA facility. At December 31, 2013, we had segregated security deposits, overhaul rentals and rental payments aggregating approximately $450.4 million related to aircraft funded under the 2004 ECA facility. The segregated amounts fluctuate with changes in security deposits, overhaul rentals, rental payments and principal and interest payments related to the aircraft funded under the 2004 ECA facility. In addition, if a default resulting in an acceleration of the obligations under the 2004 ECA facility were to occur, pursuant to the cross-collateralization agreement described below, we would have to segregate lease payments, overhaul rentals and security deposits received after such acceleration event occurred from the leases relating to all the aircraft funded under the 1999 ECA facility that remain as collateral, even though those aircraft are no longer subject to a loan at December 31, 2013.
In addition, we must register the existing individual mortgages on certain aircraft funded under both the 1999 and 2004 ECA facilities in the local jurisdictions in which the respective aircraft are registered. The mortgages are only required to be filed with respect to aircraft that have outstanding loan balances or otherwise as agreed in connection with the cross-collateralization agreement described below.
We have cross-collateralized the 1999 ECA facility with the 2004 ECA facility. As part of such cross-collateralization we (i) guaranteed the obligations under the 2004 ECA facility through our subsidiary established to finance Airbus aircraft under the 1999 ECA facility; (ii) granted mortgages over certain aircraft financed under the 1999 ECA facility and security interests over other collateral related to the aircraft financed under the 1999 ECA facility to secure the guaranty obligation; (iii) must maintain a loan-to-value ratio (aggregating the aircraft from the 1999 ECA facility and the 2004 ECA facility) of no more than 50%, in order to release liens (including the liens incurred under the cross-collateralization agreement) on any aircraft financed under the 1999 or 2004 ECA facilities or other assets related to the aircraft; and (iv) agreed to apply proceeds generated from certain disposals of aircraft to obligations under the 2004 ECA facility.
On May 8, 2013, we amended our 2004 ECA facility, effective immediately, to remove the minimum consolidated tangible net worth covenant. In addition, the amendment made permanent the requirement to segregate funds and to register individual mortgages in local jurisdictions. Prior to the amendment, this requirement would have fallen away if our long-term debt ratings rose above a certain level.
Ex-Im Financings
On December 19, 2012, through a consolidated entity, we issued pre-funded amortizing notes with an aggregate principal amount of $287.0 million. The notes mature in January 2025 and scheduled principal payments commenced in April 2013. The notes are guaranteed by the Export-Import Bank of the United States and bear interest at a rate per annum equal to 1.492%. During the year ended December 31, 2013, we used the proceeds from the notes to finance two Boeing 777-300ER aircraft, which serve as collateral for the notes.
Secured Bank Debt
2011 Secured Term Loan. On March 30, 2011, one of our indirect, wholly owned subsidiaries entered into a secured term loan agreement with lender commitments in the amount of approximately $1.3 billion, which was subsequently increased to approximately $1.5 billion. As of December 31, 2013, approximately $1.3 billion was outstanding under this agreement. The loan matures on March 30, 2018. The loan bears interest at LIBOR plus a margin of 2.75%, or, if applicable, a base rate plus a margin of 1.75%. The obligations of the subsidiary borrower are guaranteed on an unsecured basis by ILFC and on a secured basis by certain wholly owned subsidiaries of the subsidiary borrower. The security granted includes a portfolio of 54 aircraft, together with the attached leases and all related equipment, and the equity interests in certain SPEs that own the pledged aircraft, attached leases, and related equipment. The 54 aircraft had an initial aggregate appraised value, as defined in the loan agreement, of approximately $2.4 billion, which equaled a loan-to-value ratio of approximately 65%. The subsidiary borrower, subsidiary guarantors and SPEs have been designated as non-restricted subsidiaries under our indentures.
The subsidiary borrower is required to maintain compliance with a maximum loan-to-value ratio, which declines over time, as set forth in the term loan agreement. If the subsidiary borrower does not maintain compliance with the maximum loan-to-value ratio, it will be required to prepay portions of the outstanding loans, deposit an amount in the cash collateral account or transfer additional aircraft to the SPEs, subject to certain concentration criteria, so that the ratio is equal to or less than the maximum loan-to-value ratio.
The subsidiary borrower can voluntarily prepay the loan at any time. The loan facility contains customary covenants and events of default, including covenants that limit the ability of the subsidiary borrower and its subsidiaries to incur additional indebtedness and create liens, and covenants that limit the ability of ILFC, the subsidiary borrower and its subsidiaries to consolidate, merge or dispose of all or substantially all of their assets and enter into transactions with affiliates.
AeroTurbine Revolving Credit Agreement. AeroTurbine has a credit facility that expires on December 9, 2015 and provides for a maximum aggregate available amount of $430 million, subject to availability under a borrowing base calculated based on AeroTurbine's aircraft assets and accounts receivable. AeroTurbine has the option to increase the aggregate amount available under the facility by an additional $70 million, either by adding new lenders or allowing existing lenders to increase their commitments if they choose to do so. Borrowings under the facility bear interest determined, with certain exceptions, based on LIBOR plus a margin of 3.0%. AeroTurbine's obligations under the facility are guaranteed by ILFC on an unsecured basis and by AeroTurbine's subsidiaries (subject to certain exclusions) and are secured by substantially all of the assets of AeroTurbine and its subsidiary guarantors. The credit agreement contains customary events of default and covenants, including certain financial covenants. Additionally, the credit agreement imposes limitations on AeroTurbine's ability to pay dividends to us (other than dividends payable solely in common stock). As of December 31, 2013, AeroTurbine had approximately $380.5 million outstanding under the facility.
Secured Commercial Bank Financings. In May 2009, ILFC provided $39.0 million of subordinated financing to an indirect, wholly owned subsidiary that has been designated as non-restricted under our indentures. The entity used these funds and an additional $106.0 million borrowed from third parties to purchase an aircraft, which it leases to an airline. The loans had original maturity dates in May 2018 with interest rates based on LIBOR. On January 16, 2013, the subsidiary repaid both loans in full. In connection with the prepayment of these loans, we recognized losses aggregating $1.7 million from the write off of unamortized deferred financing costs.
In June 2009, ILFC borrowed $55.4 million through an indirect, wholly owned subsidiary that had been designated as non-restricted, under our indentures and that owns one aircraft leased to an airline. The loan partly amortized over five years with the remaining $27.5 million originally due in 2014 and the interest rate was fixed at 6.58%. On March 20, 2013, we repaid the loan in full. In connection with the prepayment of this loan, we recognized losses aggregating $0.8 million from the write off of unamortized deferred financing costs.
In March 2012, one of our indirect, wholly owned subsidiaries that had been designated as non-restricted under our indentures entered into a $203 million term loan facility that was used to finance seven Boeing 737-800s. The principal of each senior loan issued under the facility will partially amortize over six years, with the remaining principal payable at the maturity date. At December 31, 2013, approximately $173.5 million was outstanding and the average interest rate on the loans was 4.73%. The loans are non-recourse to ILFC except under limited circumstances and are secured by the purchased aircraft and lease receivables. The subsidiary borrower can voluntarily prepay the loans at any time subject to a 1% prepayment fee between March 30, 2014 and March 30, 2015. On March 29, 2013, we amended certain financial covenants under our $203 million term loan facility. The subsidiary borrower under the $203 million term loan facility is prohibited from: (i) incurring additional debt; (ii) incurring additional capital expenditures; (iii) hiring employees; and (iv) negatively pledging the assets securing the facility.
Institutional Secured Term Loans
In 2012, we entered into the following term loans:
•Secured Term Loan 2012-1: On February 23, 2012, one of our indirect, wholly owned subsidiaries that had been designated as non-restricted under our indentures entered into a secured term loan agreement in the amount of $900 million. The loan matures on June 30, 2017, and initially bore interest at LIBOR plus a margin of 4.0% with a 1.0% LIBOR floor, or, if applicable, a base rate plus a margin of 3.0%. On April 5, 2013, we amended this secured term loan and simultaneously prepaid $150 million of the outstanding principal amount. In connection with the partial prepayment of this secured term loan, we recognized losses aggregating approximately $2.9 million from the write off of unamortized deferred financing costs. The remaining outstanding principal amount of $750 million now bears interest at an annual rate of LIBOR plus 2.75%, with a LIBOR floor of 0.75%, or, if applicable, a base rate plus a margin of 1.75%. The obligations of the subsidiary borrower are guaranteed on an unsecured basis by ILFC and on a secured basis by certain wholly owned subsidiaries of the subsidiary borrower. The security granted includes the equity interests in certain SPEs of the subsidiary borrower that have been designated as non-restricted under our indentures. The SPEs initially held title to 62 aircraft, together with the attached leases and all related equipment, with an aggregate appraised value, as defined in the loan agreement, of approximately $1.66 billion as of December 31, 2011, equaling an initial loan-to-value ratio of approximately 54%. After giving effect to the amendment, certain collateral that had served as security for the secured term loan was released. As of December 31, 2013, the SPEs collectively own a portfolio of 52 aircraft, together with the attached leases and all related equipment, with an aggregated appraised value of $1.22 billion, equaling a loan-to-value ratio of approximately 61.5%. The loan requires a loan-to-value ratio of no more than 63%. If the subsidiary borrower does not maintain compliance with the maximum loan-to-value ratio, it will be required to prepay a portion of the outstanding loan, deposit an amount in the cash collateral account or transfer additional aircraft to SPEs, subject to certain concentration criteria, so that the ratio is equal to or less than the maximum loan-to-value ratio. The principal of the loan is payable in full at maturity with no scheduled amortization. We can voluntarily prepay the loan at any time. The loan contains customary covenants and events of default, including covenants that limit the ability of the subsidiary borrower and its subsidiaries to incur additional indebtedness and create liens, and covenants that limit the ability of ILFC, the subsidiary borrower and its subsidiaries to consolidate, merge or dispose of all or substantially all of their assets and enter into transactions with affiliates.
•Secured Term Loan 2012-2: On April 12, 2012, one of our indirect, wholly owned subsidiaries that had been designated as non-restricted under our indentures entered into a secured term loan agreement in the amount of $550 million. The loan had an original maturity date of April 12, 2016, and bore interest at LIBOR plus a margin of 3.75% with a 1% LIBOR floor. The obligations of the subsidiary borrower were guaranteed on an unsecured basis by ILFC and on a secured basis by certain wholly owned subsidiaries of the subsidiary borrower. We prepaid this loan in full on May 30, 2013, and in connection with the prepayment, we recognized losses aggregating approximately $12.3 million from the write-off of unamortized deferred discount and financing costs.
Unsecured Bonds and Medium-Term Notes
Shelf Registration Statement. Predecessor had an effective shelf registration statement filed with the SEC. We had an unlimited amount of debt securities registered for sale under the shelf registration statement.
At December 31, 2013, we had issued unsecured notes with an aggregate principal amount outstanding of approximately $9.5 billion under our current and previous shelf registration statements, including $750 million of 3.875% notes due 2018 and $500 million of 4.625% notes due 2021, each issued in March 2013; and $550 million of floating rate notes due 2016, issued in May 2013. The floating rate notes bear interest at three-month LIBOR plus a margin of 1.95%, with the interest rate resetting quarterly. At December 31, 2013, the interest rate was 2.193%. The debt securities outstanding under our shelf registration statements mature through 2022 and the fixed rate notes bear interest at rates ranging from 3.875% to 8.875%. The notes are not subject to redemption prior to their stated maturity and there are no sinking fund requirements.
Other Senior Notes. On March 22, 2010 and April 6, 2010, we issued a combined $1.25 billion aggregate principal amount of 8.625% senior notes due September 15, 2015, and $1.5 billion aggregate principal amount of 8.750% senior notes due March 15, 2017, pursuant to an indenture dated as of March 22, 2010. The notes are not subject to redemption prior to their stated maturity and there are no sinking fund requirements.
The indentures governing our unsecured notes contain customary covenants that, among other things, restrict our, and our restricted subsidiaries', ability to (i) incur liens on assets; (ii) declare or pay dividends or acquire or retire shares of our capital stock during certain events of default; (iii) designate restricted subsidiaries as non-restricted subsidiaries or designate non-restricted subsidiaries; (iv) make investments in or transfer assets to non-restricted subsidiaries; and (v) consolidate, merge, sell, or otherwise dispose of all or substantially all of our assets.
The indentures also provide for customary events of default including, but not limited to, the failure to pay scheduled principal and interest payments on the notes, the failure to comply with covenants and agreements specified in the indenture, the acceleration of certain other indebtedness resulting from non-payment of that indebtedness and certain events of insolvency. If any event of default occurs, any amount then outstanding under the relevant indentures may immediately become due and payable.
Unsecured Revolving Credit Agreement
2012 Credit Facility. On October 9, 2012, we entered into a $2.3 billion three-year unsecured revolving credit facility with a group of 10 banks that expires on October 9, 2015. Our revolving credit facility provides for interest rates based on either a base rate or LIBOR plus a margin, currently 2.00%, determined by reference to our ratio of consolidated indebtedness to shareholders' equity. The credit agreement contains customary events of default and restrictive covenants that, among other things, limit our ability to incur liens and transfer or sell assets. The credit agreement also contains financial covenants that require us to maintain a minimum interest coverage ratio and a maximum ratio of consolidated indebtedness to shareholders' equity. As of December 31, 2013, we had not drawn on our revolving credit facility.
In connection with our pending sale to AerCap, on January 28, 2014, we amended our $2.3 billion revolving credit facility. The amendment will only become effective upon the occurrence of certain conditions, including the consummation of the pending sale of us to AerCap. As part of the amendments to our revolving credit facility, AerCap and certain of its subsidiaries will be required to guarantee our obligations under the revolving credit facility and the cross-default provision will extend to defaults on certain indebtedness of AerCap or any of its subsidiaries that are guarantors at such time under the revolving credit agreement. The amendments to the revolving credit facility also add financial covenants and revise other financial and restrictive covenants. The new and revised financial covenants will be measured on a consolidated basis for AerCap and its subsidiaries.
Subordinated Debt
In December 2005, we issued two tranches of subordinated debt totaling $1.0 billion. Both tranches mature on December 21, 2065. The $400 million tranche has a call option date of December 21, 2015. The $400 million tranche has a fixed interest rate of 6.25% until the 2015 call option date. If we do not exercise the call option, the interest rate will change to a floating rate, reset quarterly, based on a margin of 1.80% plus the highest of (i) 3 month LIBOR; (ii) 10-year constant maturity treasury; and (iii) 30-year constant maturity treasury. We can call the $600 million tranche at any time. The interest rate on the $600 million tranche is a floating rate with a margin of 1.55% plus the highest of (i) 3 month LIBOR; (ii)10-year constant maturity treasury; and (iii) 30-year constant maturity treasury. The interest rate resets quarterly. At December 31, 2013, the interest rate was 5.46%. If we choose to redeem the $600 million tranche, we must pay 100% of the principal amount of the bonds being redeemed, plus any accrued and unpaid interest to the redemption date. If we choose to redeem only a portion of the outstanding bonds, at least $50 million principal amount of the bonds must remain outstanding.
Under the terms of the subordinated debt, failure to comply with a financial test requiring a minimum ratio of equity to total managed assets and a minimum fixed charge coverage ratio will result in a "mandatory trigger event". If a mandatory trigger event occurs and we are unable to raise sufficient capital through capital contributions from AIG or the sale of our stock (in the manner permitted by the terms of the subordinated debt) to cover the next interest payment on the subordinated debt, a "mandatory deferral event" will occur. If a mandatory deferral event occurs, we would be required to defer all interest payments on the subordinated debt and be prohibited from paying cash dividends on our capital stock (including our market auction preferred stock) until we are in compliance with both financial tests or have raised sufficient capital to pay all accumulated and unpaid interest on the subordinated debt. Mandatory trigger events and mandatory deferral events are not events of default under the indenture governing the subordinated debt.
On July 25, 2013, we amended the financial tests in both tranches of subordinated debt after a majority of the holders of the subordinated debt consented to such amendments. The financial tests were amended by (i) replacing the definition of "Tangible Equity Amount" used in calculating our ratio of equity to total managed assets with a definition for "Total Equity Amount" that does not exclude intangible assets from our total stockholders' equity as reflected on our consolidated balance sheet, and (ii) amending the calculation of the earnings portion of our minimum fixed charge coverage ratio by replacing the definition of "Adjusted Earnings Before Interest and Taxes" used in calculating such ratio with a definition for "Adjusted EBITDA" that excludes, among other items, interest, taxes, depreciation, amortization, all impairment charges and loss on extinguishment of debt. These amendments make it less likely that we will fail to comply with such financial tests.

	Successor
	The Successor, a Delaware statutory trust, is a pass-through entity that is not subject to tax in the U.S. or Ireland. Rather, its beneficiaries AerCap Ireland Capital Limited and ILFC, are subject to tax. As the majority of the Successor's income and expense is subject to tax by AerCap Ireland Capital Limited, an Irish limited company, the Successor is presented as an Irish tax resident whose earnings are subject to Irish corporate income tax.
	The Successor's effective tax rate for the period beginning February 5, 2014 and ending December 31, 2014, was 15.6%. The Successor's effective tax rate is lower than the Predecessor's primarily due to the effect of the Reorganization, which resulted in the majority of the Successor's earnings now being taxed at the lower Irish income tax rate. See Note 3—AerCap Transaction.
	The following table presents Successor income before income taxes for the locations in which such pre-tax income was earned or incurred.

Net Deferred Tax Liability		$	134,545


As of December 31, 2014, before any valuation allowance, the Successor had a U.S. deferred tax asset of $66.5 million, including $3.2 million U.S. federal net operating losses, which expire in 2034. Due to the Reorganization, we do not expect to generate sufficient sources of taxable income to fully realize our deferred tax asset, and have recorded a $25.0 million partial valuation allowance.
In addition, we have gross Irish net operating loss carryforwards of $1,749.9 million, as of December 31, 2014. Our Irish net operating loss carryforwards do not expire and were not impacted by the Reorganization. In Australia, because we do not expect to generate sufficient sources of taxable income to fully utilize our foreign net operating loss carryforwards and capital loss carryforward, we have recorded a valuation allowance against our entire deferred tax asset of $36.9 million as of December 31, 2014. Although it is reasonably possible that a change in the balance of our valuation allowance may occur within the next 12 months, based on the information currently available, we do not expect any change to be material to our consolidated financial condition.
In making our assessment of the realization of the deferred tax assets, including net operating loss carryforwards, we considered all available evidence, including (i) the projected amount, nature and timing of the realization of deferred tax liabilities; (ii) current and projected taxable income; (iii) implications of the tax sharing agreement with AIG for the Predecessor; and (iv) tax planning strategies.
The Successor is considered an Irish tax resident with a statutory tax rate of 12.5%. A reconciliation of the expected total provision at the statutory tax rate for income taxes to the amount recorded is as follows:

		Successor

Unrecognized tax benefits at beginning of period		$	5,421
Additions based on tax positions related to current period			7,027

Unrecognized tax benefits at end of period		$	12,448


Substantially all of the unrecognized tax benefits as of December 31, 2014, if recognized, would affect our effective tax rate. Although it is reasonably possible that a change in the balance of unrecognized tax benefits may occur within the next 12 months, based on the information currently available, we do not expect any change to be material to our consolidated financial condition. The unrecognized tax benefits and interest accrued during the Predecessor periods remain with AIG.
Interest and penalties related to unrecognized tax benefits are recognized in income tax expense. Successor did not recognize any interest or penalties related to unrecognized tax benefits during the period beginning February 5, 2014 and ending December 31, 2014.
We regularly evaluate adjustments proposed by taxing authorities. At December 31, 2014, such proposed adjustments would not have resulted in a material change to our consolidated financial condition, although it is possible that the effect could be material to our consolidated results of operations for an individual reporting period.
Although we operate in various countries throughout the world, the major tax jurisdictions in which we operate in are the United States and Ireland. The Successor's U.S. corporate subsidiaries will file their first U.S. federal income tax returns for tax year 2014, which is subject to examination. In Ireland, we are subject to examination for tax years from 2010 through 2013.

Our foreign entities are generally treated as foreign disregarded entities of a U.S. corporation for U.S federal income tax purposes in the Predecessor period. Accordingly, the foreign income is also subject to U.S. federal income tax on a current basis.

The Predecessor was included in the consolidated federal income tax return of AIG as well as certain state tax returns where AIG files on a combined/unitary basis. Under the tax sharing agreement with AIG, Predecessor settled the current tax liability as if the Predecessor and its subsidiaries were each a separate standalone taxpayer. Thus, AIG credited the Predecessor to the extent the net operating losses, foreign tax credits and other tax benefits (calculated on a separate return basis) were used in AIG's consolidated tax return and charged the Predecessor to the extent of the current tax liability (calculated on a separate return basis). Predecessor's tax sharing agreement with AIG was terminated upon consummation of the AerCap Transaction.
The net deferred tax liability consists of the following:

		Predecessor
(Dollars in thousands)		December 31,

In July 2013, the FASB issued an accounting standard that requires a liability related to unrecognized tax benefits to be presented as a reduction to the related deferred tax asset for a net operating loss carryforward or a tax credit carryforward. Predecessor adopted the standard prospectively on January 1, 2014. Prior to the adoption of the standard, U.S. federal net operating losses were generally presented gross of any unrecognized tax benefits and classified as deferred tax assets to the extent they exceeded the amount of the unrecognized tax benefit for that year. Due to the adoption of the standard, $127.4 million of Predecessor unrecognized tax benefits as of January 1, 2014 have been presented as a reduction of deferred tax assets for net operating losses instead of reported as a component within Current income taxes and other tax liabilities.
Predecessor U.S. federal net operating losses were generally classified as deferred tax assets due to uncertainties with regard to the timing of their future utilization in the consolidated tax return of AIG. On a separate tax return basis, Predecessor had U.S. federal gross net operating loss carryforwards of $779.9 million for December 31, 2013. Predecessor's U.S. federal net operating loss carryforwards expire beginning in 2028. In addition, as of December 31, 2013, Predecessor also had gross foreign net operating loss carryforwards of $300.7 million. The foreign net operating loss carryforwards do not expire. In Australia, because Predecessor did not expect to generate sufficient sources of taxable income to fully utilize our foreign net operating loss carryforwards, Predecessor have recorded a valuation allowance of $15.7 million, as of December 31, 2013, resulting in a deferred tax asset, net of valuation allowance, of $0 million at December 31, 2013. Predecessor had U.S. foreign tax credits carryforwards which begin to expire in 2018 and certain state net operating loss carryforwards which begin to expire in 2026.
In making our assessment of the realization of the deferred tax assets, including net operating loss carryforwards, we considered all available evidence, including (i) the projected amount, nature and timing of the realization of deferred tax liabilities; (ii) current and projected taxable income; (iii) implications of the tax sharing agreement with AIG for the Predecessor; and (iv) tax planning strategies.
A reconciliation of the expected total provision at the statutory tax rate for income taxes to the amount recorded is as follows:

The Predecessor was periodically advised of certain IRS and other adjustments identified in AIG's consolidated tax return which were attributable to our operations. Under the tax sharing arrangement with AIG, the Predecessor provided a charge or credit for the effect of the adjustments and the related interest in the period we were advised of such adjustments and interest. The Predecessor recognized $1.0 million, $(0.5) million and $(2.8) million of IRS audit adjustments in the Consolidated Statement of Operations for the period beginning January 1, 2014 and ending May 13, 2014, and for the years ended December 31, 2013 and 2012, respectively.
In May 2012, a decision in favor of a taxpayer was granted whereby the U.S. Court of Federal Claims held that in calculating the gain realized upon the sale of an asset under the Foreign Sales Corporation regime, the asset's adjusted tax basis should not be reduced by the amount of disallowed depreciation deductions allocable to tax-exempt foreign trade income. Based upon the decision reached in the case, the Predecessor adjusted its tax basis in certain flight equipment and recorded an income tax benefit of approximately $601 million and a corresponding reserve of $438.5 million for uncertain tax positions, resulting in a net tax benefit of $162.6 million.
A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

		Predecessor

Interest and penalties related to unrecognized tax benefits are recognized in income tax expense. Predecessor recognized $0.8 million, $8.5 million, and $2.7 million of interest, net of the federal benefit, in the Consolidated Statements of Operations for the period beginning January 1, 2014 and ending May 13, 2014, and for the years ended December 31, 2013 and 2012, respectively. At December 31, 2013, we had accrued $20.2 million for the payment of interest, net of the federal tax benefit. At December 31, 2013 and 2012, the amounts of unrecognized tax benefits that, if recognized, would favorably affect the tax rate were $809.0 million and $725.7 million, respectively.
We regularly evaluate adjustments proposed by taxing authorities. At May 13, 2014 and December 31, 2013, such proposed adjustments would not have resulted in a material change to our consolidated financial condition, although it is possible that the effect could be material to our consolidated results of operations for an individual reporting period. Although it is reasonably possible that a change in the balance of unrecognized tax benefits may occur within the next 12 months, based on the information currently available, we do not expect any change to be material to our consolidated financial condition.
Although we operate in various countries throughout the world, the major tax jurisdictions in which we operate in are the U.S. and Ireland. In the U.S., we were included in AIG's consolidated federal income tax return, which is currently under examination for tax years 2000 through 2006. The statute of limitation for all years prior to 2000 has expired for Predecessor consolidated federal tax return. In Ireland, we are subject to examination for tax years from 2009 through 2012.

	The MAPS have a liquidation value of $100,000 per share and are not convertible. The dividend rate, other than the initial rate, for each dividend period for each series is to be reset approximately every seven weeks (49 days) on the basis of orders placed in an auction, provided such auctions are able to occur. At December 31, 2013, the dividend rate for Series A MAPS was 0.193% and the dividend rate for Series B MAPS was 0.223%. During 2012, there was no ability to conduct such auctions. Therefore, the MAPS certificates of determination dictate that a "maximum applicable rate" (as calculated on each auction date pursuant to the certificates of determination) be paid on the MAPS.
	Paid-in Capital
	Successor
	During the period beginning February 5, 2014 and ending December 31, 2014, we recorded $14.9 million in stock compensation for AerCap share-based awards, as a capital contribution in Paid-in-capital.
	Predecessor
	During the period beginning January 1, 2014 and ending May 13, 2014, we recorded an increase of $0.3 million, net of tax of $0.2 million in connection with settlement of the AIG Non-Qualified Income Plan liability, and a decrease of $0.2 million for adjustments to state taxes payable.
	AIG did not pay any expenses on our behalf during the period beginning January 1, 2014 and ending May 13, 2014. Predecessor recorded approximately $10.1 million and $2.6 million in Paid-in capital for the years ended December 31, 2013 and 2012, respectively, for compensation, legal fees and other expenses paid by AIG on our behalf for which we were not required to reimburse.
	In addition, in 2012 Predecessor received one corporate aircraft from AIG and recorded $16.7 million, net of taxes of $9.2 million, as a capital contribution in Paid-in capital to reflect the transaction.
	Accumulated Other Comprehensive (Loss) Income
	Successor
	The balance in Accumulated other comprehensive loss as of the Closing Date was eliminated when we applied the acquisition method of accounting.
	Subsequent to the AerCap Transaction we sold all available-for-sale securities and our interest rate swaps no longer qualify for hedge accounting. As a result, at December 31, 2014, there is no remaining balance in AOCI.
	Predecessor
	Predecessor Accumulated other comprehensive loss consisted of changes in fair value of derivative instruments that qualified as cash flow hedges and unrealized gains and losses on marketable securities classified as "available-for-sale". The fair value of derivatives is based upon a model that employes current interest and volatility rates as well as other observable inputs, as applicable. The fair value of marketable securities was determined using quoted prices.
	The following table presents a rollforward of Accumulated other comprehensive loss for the Predecessor period beginning January 1, 2014 and ending May 13, 2014 and for the years ended December 31, 2013 and 2012:

Retained Earnings
Predecessor
On May 13, 2014, Predecessor paid a special distribution of $600.0 million, which it was required to pay to AIG prior to the completion of the AerCap Transaction, in accordance with the Share Purchase Agreement. The special distribution was recorded in Retained earnings as a dividend. An additional $1.4 million was recorded in Retained earnings as a dividend, when Predecessor paid a fee to satisfy a statutory law requirement on behalf of AIG. Additionally, Predecessor recorded a decrease in Retained earnings of $5.3 million, net of tax of $2.9 million, to record a non-cash dividend reflecting the difference between the proceeds received and the net carrying value of a corporate aircraft sold to AIG. Predecessor recorded an increase to Retained earnings of $9.6 million for a receipt from AIG for certain expected separate company tax liabilities, as required under the AerCap sales agreement.
Predecessor recorded the following as dividends charged to Retained Earnings for the following years: $0.9 million in 2013 when we transferred AIG stock to AIG and $25.4 million, net of taxes of $11.9 million in 2012, when we transferred two corporate aircraft to AIG.

Asset Impairment

20. Asset Impairment

We periodically dispose of aircraft from our fleet held for use prior to the conclusion of their economic useful life through either a sale or part-out. As part of the recoverability assessment of our fleet, management assesses potential transactions and the likelihood that each individual aircraft will continue to be held for use as part of our leased fleet or if the aircraft will be disposed of through either a sale or part-out. If management determines that it is more likely than not that an aircraft will be disposed of through either a sale or part-out as a result of a potential transaction, a recoverability assessment is performed by comparing the carrying amount of the aircraft to the estimated future undiscounted cash flows expected to be generated by the aircraft. If the future undiscounted cash flows are less than the aircraft carrying amount, the aircraft is impaired and is re-measured to fair value in accordance with our Fair Value Policy. See Note 26—Fair Value Measurements. The difference between the fair value and the carrying amount of the aircraft is recognized as an impairment or fair value adjustment in our Consolidated Statements of Operations. Further, if the aircraft meets the criteria to be classified as Flight equipment held for sale, we will reclassify the aircraft from Flight equipment into Flight equipment held for sale (subsequent to recording any necessary impairment charges or fair value adjustments).

Successor

Successor recorded impairments of $7.2 million for the period beginning February 5, 2014 and ending December 31, 2014, primarily related to six Boeing 757-200 aircraft that were returned early from our lessees, and four engines and one airframe, which were parted-out subsequent to the AerCap Transaction. The impairment was recognized as the net book values were no longer supported based on the latest cash flow estimates.

Predecessor

Aircraft Impairment Charges on Flight Equipment Held for Use

Year ended December 31, 2013

During the year ended December 31, 2013, Predecessor recorded impairment charges of $1.2 billion relating to 44 aircraft, primarily in connection with its third quarter of 2013 recoverability assessment whereby Predecessor concluded that the net book values of certain four-engine widebody aircraft in its fleet were no longer supportable based upon the latest cash flow estimates because the estimated holding periods were not likely to be as long as previously anticipated. The increasing number of aircraft operators looking to completely or partially replace their Airbus A340s and Boeing 747s is expected to increase the available supply of these aircraft types and diminish future lease placement opportunities. Sustained high fuel prices, the introduction of more fuel-efficient aircraft, and the success of competing aircraft models have resulted in a shrinking operator base for these aircraft types. These factors along with the latest updates to airline fleet plans and recent efforts to remarket these aircraft informed the Predecessor's conclusions. Approximately $1.0 billion of the $1.2 billion of impairment charges recorded for the year ended December 31, 2013, resulted from the four-engine widebody aircraft and in particular the Airbus A340-600s, which has a limited operator base.

In connection with our recoverability assessment of aircraft performed in the third quarter of 2013, Predecessor re-assessed the estimated holding period for certain aircraft types and, as a result, changed the estimated economic useful life of 55 aircraft in its fleet, including 32 aircraft that were impaired during the third quarter of 2013. In the fourth quarter of 2013, Predecessor started depreciating these aircraft using the straight-line method over their estimated remaining revised useful lives. This change accelerates the overall depreciation expense on these aircraft but will be partially offset by the reduction in the carrying values of the 32 aircraft for which impairment charges were recorded during the third quarter of 2013. These changes, absent any other changes to the carrying value of these aircraft in the ordinary course of business, would result in an increase in Predecessor 2014 depreciation expense for these aircraft of approximately $23 million. Beginning in 2015, depreciation expense for these aircraft is expected to decrease as these aircraft begin to reach the end of their respective estimated useful lives.

Year ended December 31, 2012

During the year ended December 31, 2012, Predecessor recorded impairment charges aggregating $102.7 million relating to ten aircraft. Of the $102.7 million in impairment charges recognized, $100.2 million related to the recurring recoverability assessments, and $2.5 million related to the repossession and early return of one aircraft that was leased to an airline that ceased operations during the year ended December 31, 2012.

Aircraft Impairment Charges and Fair Value Adjustments on Flight Equipment Sold or to be Disposed

We reported the following impairment charges and fair value adjustments on flight equipment sold or to be disposed for the period beginning January 1, 2014 and ending May 13, 2014 and during the years ended December 31, 2013, and 2012:

Employee Benefit Plans and Share-Based and Other Compensation Plans
Employee Benefit Plans and Share-Based and Other Compensation Plans	22. Employee Benefit Plans and Share-Based and Other Compensation Plans
	Prior to the AerCap Transaction, our employees participated in various AIG benefit plans, including a noncontributory qualified defined benefit retirement plan ("AIG Retirement Plan") and various share-based and other compensation plans. During 2012, ILFC set up its own voluntary savings plan ("ILFC 401(k) plan") and transferred all participating employee's savings from the 401(k) plan sponsored by AIG. Subsequent to the AerCap Transaction, changes were made to certain of these plans and some were replaced by other plans.
	Pension Plans
	Predecessor
	Pension plan expenses include amounts allocated to us by AIG for our U.S employees and pension plan expenses related to our employees working in foreign offices. AIG's U.S. benefit plans do not separately identify projected benefit obligations and plan assets attributable to employees of participating affiliates.
	AIG's projected benefit obligations exceeded the plan assets at December 31, 2013 by approximately $858 million.
	On April 1, 2012, the AIG Retirement Plan was converted from final average pay to cash balance formulas comprised of pay credits based on six percent of a plan participant's annual compensation (subject to IRS limitations) and annual interest credits. However, employees satisfying certain age and service requirements (i.e. grandfathered employees) remain covered under the old plan formula, which is based upon a percentage of final average compensation multiplied by years of credited service, up to 44 years.
	AIG also sponsors non-qualified unfunded defined benefit plans for certain employees, including key executives, designed to supplement pension benefits provided by the qualified plan. These include the AIG Non-Qualified Retirement Income Plan, which provides a benefit equal to the reduction in benefits payable to current and former employees under the qualified plan as a result of federal tax limitations on compensation and benefits payable.
	The ILFC 401(k) plan expense primarily represents our cost of matching employee contributions up to a fixed percentage limit.
	Pension plan and 401(k) plan expenses were $4.8 million for the period beginning January 1, 2014 and ending May 13, 2014, $9.5 million for 2013 and $4.9 million for 2012.
	Successor
	ILFC employees who had at least one year of service participated in the AIG Retirement Plan and their individual accounts became fully vested at the Closing Date. Such accounts will be managed directly by AIG. Subsequent to the AerCap Transaction, these ILFC employees ceased accruing benefits under the AIG Retirement Plan and instead will receive an additional contribution to their ILFC 401(k) plan. Employees who complete one year of service subsequent to the Closing Date will also receive an additional contribution to their ILFC 401(k) plan.
	In June 2014, AerCap paid AIG $19.8 million for the liability associated with our employees or former employees who were fully vested in the AIG Non-qualified Retirement Plan as of May 13, 2014. As a result of this payment, these plan participants' benefit obligation will be managed directly by AIG. The obligation for the participants with unvested balances in the AIG Non-qualified Retirement Plan were transferred to an AerCap non-qualified plan.
	Subsequent to the AerCap Transaction, the ILFC 401(k) plan expense also includes the additional contribution made in lieu of employees' participation in the AIG Retirement Plan.
	Pension plan and 401(k) plan expenses were not material to the Successor period.
	Share-Based and Other Compensation Plans
	Predecessor
	Prior to the AerCap Transaction, certain of our employees participated in the following AIG share-based and other compensation plans: (i) stock salary, variable stock plan and restricted stock unit awards; and (ii) short and long term incentive awards. For the period beginning January 1, 2014 and ending May 13, 2014, we recorded compensation expense of $1.8 million under the AIG's share-based programs, and $15.0 million for our short and long-term incentive plans. In addition, executives employed by ILFC as of a certain date were eligible for a bonus that was payable upon the closing of the AerCap Transaction. We began to accrue for this in December 2013 when the transaction was announced. During the period beginning January 1, 2014 and ending May 13, 2014, we accrued $32.3 million for this bonus. We recorded compensation expenses of $14.8 million and $15.4 million for our participation in AIG's share-based programs and $45.7 million and $33.2 million our short and long-term incentive plans for the years ended December 31, 2013 and 2012, respectively. The impact of all plans, both individually and in the aggregate, is immaterial to the consolidated financial statements.
	Successor
	We recorded the following compensation expense for share-based and other compensation plans for the Successor period:

Currency Risk
Our functional currency is U.S. dollars. Foreign exchange risk arises from our and our lessees' operations in multiple jurisdictions. All of our aircraft purchase agreements are negotiated in U.S. dollars, we currently receive substantially all of our revenue in U.S. dollars and we pay substantially all of our expenses in U.S. dollars. We currently have a limited number of leases denominated in foreign currencies, maintain part of our cash in foreign currencies, pay taxes in foreign currencies and incur some of our expenses in foreign currencies, primarily the Euro. A decrease in the U.S. dollar in relation to foreign currencies increases our expenses paid in foreign currencies and an increase in the U.S. dollar in relation to foreign currencies decreases our lease revenue received from foreign currency denominated leases. Because we currently receive most of our revenues in U.S. dollars and pay most of our expenses in U.S. dollars, a change in foreign exchange rates would not have a material impact on our results of operations or cash flows. We do not have any restrictions or repatriation issues associated with our foreign cash accounts.

Commitments and Contingencies.
Commitments and Contingencies	24. Commitments and Contingencies
	Aircraft Orders
	At December 31, 2014, we had commitments to purchase 347 new aircraft and 17 new spare engines scheduled for delivery through 2022 with aggregate estimated total remaining payments (including adjustments for certain contractual escalation provisions) of approximately $21.6 billion. The majority of these commitments to purchase new aircraft and engines are based upon agreements with each of Boeing, Airbus, Embraer and Pratt and Whitney.
	The Boeing aircraft (models 737 and 787), the Airbus aircraft (models A320neo, A321neo, A321 and A350XWB), and the Embraer E-Jets E2 aircraft are primarily being purchased pursuant to the terms of purchase agreements executed by us and Boeing, Airbus, or Embraer. These agreements establish the pricing formulas (including adjustments for certain contractual escalation provisions) and various other terms with respect to the purchase of aircraft. Under certain circumstances, we have the right to alter the mix of aircraft types ultimately acquired. As of December 31, 2014, we had made non-refundable deposits on these purchase commitments (exclusive of capitalized interest and fair value adjustments) of approximately $456.8 million, $188.4 million, and $7.5 million with Boeing, Airbus, and Embraer, respectively.
	Management anticipates that a portion of the aggregate purchase price for the acquisition of aircraft will be funded by incurring additional debt. The amount of the indebtedness to be incurred will depend upon the final purchase price of the aircraft, which can vary due to a number of factors, including inflation.
	Movements in Prepayments on flight equipment (including related capitalized interest) during the period beginning February 5, 2014 and ending December 31, 2014 were as follows:

	Asset Value Guarantees
	Successor
	ILFC had previously contracted to provide guarantees on a portion of the residual value of aircraft owned by third parties for a fee. These guarantees expire at various dates through 2023 and generally obligate us to pay the shortfall between the fair market value and the guaranteed value of the aircraft and, in certain cases, provide us with an option to purchase the aircraft for the guaranteed value. As of December 31, 2014, 13 guarantees were outstanding, of which three were exercised. In October 2014, we entered into agreements to sell two of those aircraft in 2015. Subsequent to December 31, 2014, two of the remaining outstanding asset value guarantees with an aggregate maximum exposure of $18.1 million were terminated by the guaranteed party. The terminations had no impact on our consolidated results or cash flows.
	Management regularly reviews the underlying values of the aircraft collateral to determine our exposure under asset value guarantees. We did not record any provisions for losses on asset value guarantees during period beginning February 5, 2014 and ending December 31, 2014.
	At December 31, 2014, the carrying value of the asset value guarantee liability was $133.5 million and was included in Accrued expenses, accounts payable and other liabilities on the Successor Consolidated Balance Sheet. The maximum aggregate potential commitment that we were obligated to pay under these guarantees, including those exercised, and without any offset for the projected value of the aircraft or other contractual features that may limit our exposure, was approximately $316.6 million.
	Predecessor
	We have previously contracted to provide guarantees on a portion of the residual value of certain aircraft to financial institutions and other third parties for a fee, some of which are still outstanding. As of December 31, 2013, we provided ten such guarantees that had not yet been exercised. These guarantees expire at various dates through 2023 and generally obligate us to pay the shortfall between the fair market value and the guaranteed value of the aircraft and provide us with an option to purchase the aircraft for the guaranteed value. During the year ended December 31, 2013, we purchased five used aircraft under guarantees previously exercised, three of which we subsequently sold. We may purchase one additional aircraft during 2015 under a separate previously exercised guarantee. At December 31, 2013, the total reserves related to these asset value guarantees we have contracted to provide aggregated $125.5 million and the maximum aggregate potential commitment that we were obligated to pay under these guarantees, without any offset for the projected value of the aircraft or other features that may limit our exposure, was approximately $330.6 million.
	We did not record any provisions for losses on asset value guarantees for the period beginning January 1, 2014 and ending May 13, 2014. We recorded provisions for losses on asset value guarantees of $100.5 million related to six asset value guarantees during 2013 and $31.3 million related to three asset value guarantees during 2012.
	The Predecessor carrying balance of asset value guarantees, which consisted of unamortized deferred premiums and reserves, was $128.7 million at December 31, 2013 and was included in Accrued interest and other payables on the Predecessor Consolidated Balance Sheet.
	Leases
	We have operating leases for office space extending through 2026. Rent expense was $11.1 million for the Successor period beginning February 5, 2014 and ending December 31, 2014. The leases provide for step rentals over the term and those rentals are considered in determining the amount of rent expense to be recorded on a straight-line basis over the term of the lease. Tenant improvement allowances received from lessors are capitalized and amortized in Selling, general and administrative expenses in our Consolidated Statements of Operations as a reduction of rent expense. Commitments for minimum rentals under the non-cancelable leases at December 31, 2014, are as follows:

	Year Ended		Successor
			(Dollars in thousands)
	2015		$	13,855
	2016			7,308
	2017			7,355
	2018			6,870
	2019			5,356
	Thereafter			27,827

	Total(a)		$	68,571




	(a)	Minimum rentals have not been reduced by future minimum sublease rentals of $0.7 million under non-cancelable subleases.
	Predecessor
	Rent expense was $6.7 million, $15.5 million, and $15.9 million for the period beginning January 1, 2014 and ending May 13, 2014, and for the years ended December 31, 2013 and 2012, respectively.
	Contingencies
	Legal Proceedings
	Successor
	In the ordinary course of our business, we are a party to various legal actions, which we believe are incidental to the operations of our business. The Company regularly reviews the possible outcome of such legal actions, and accrues for such legal actions at the time a loss is probable and the amount of the loss can be estimated. In addition, the Company also reviews the applicable indemnities and insurance coverage. Based on information currently available, we believe the potential outcome of these cases, and our estimate of the reasonably possible losses exceeding amounts already recognized on an aggregated basis is immaterial to our consolidated financial condition, results of operations or cash flows.
	Yemen Airways-Yemenia: ILFC is named in a lawsuit in connection with the 2009 crash of an Airbus A310-300 aircraft owned by ILFC and on lease to Yemen Airways-Yemenia, a Yemeni carrier ("Hassanati Action"). The Hassanati plaintiffs are families of deceased occupants of the flight and seek unspecified damages for wrongful death, costs, and fees. The Hassanati Action commenced in January 2011 and is pending in the United States District Court for the Central District of California. On February 18, 2014, the district court granted summary judgment in ILFC's favor and dismissed all of the Hassanati plaintiffs' remaining claims. The Hassanati plaintiffs have appealed the judgment. On August 29, 2014, a new group of plaintiffs filed a lawsuit against ILFC in the United States District Court for the Central District of California (the "Abdallah Action"). The Abdallah Action claims unspecified damages from ILFC on the same theory as does the Hassanati Action. We believe that ILFC has substantial defenses on the merits and is adequately covered by available liability insurance in respect of both the Hassanati Action and the Abdallah Action.
	Air Lease: On April 24, 2012, ILFC and AIG filed a lawsuit in the Los Angeles Superior Court against ILFC's former CEO, Steven Udvar Hazy, Mr. Hazy's current company, Air Lease Corporation (ALC), and a number of ALC's officers and employees who were formerly employed by ILFC. The lawsuit alleges that Mr. Hazy and the former officers and employees, while employed at ILFC, diverted corporate opportunities from ILFC, misappropriated ILFC's trade secrets and other proprietary information, and committed other breaches of their fiduciary duties, all at the behest of ALC.
	The complaint seeks monetary damages and injunctive relief for breaches of fiduciary duty, misappropriation of trade secrets, unfair competition, and various other violations of state law.
	On August 15, 2013 ALC filed a cross-complaint against ILFC and AIG. Relevant to ILFC, ALC's cross-complaint alleges that ILFC entered into, and later breached, an agreement to sell aircraft to ALC. Based on these allegations, the cross-complaint asserts a claim against ILFC for breach of contract. The cross-complaint seeks significant compensatory and punitive damages. We believe we have substantial defenses on the merits and will vigorously defend ourselves against ALC's claims.
	On April 23, 2014, ILFC filed an amended complaint adding as a defendant Leonard Green & Partners, L.P. The complaint adds claims against Leonard Green & Partners, L.P. for aiding and abetting the individual defendants' breaches of their fiduciary duties and duty of loyalty to ILFC and for unfair competition.

Variable Interest Entities
Variable Interest Entities	25. Variable Interest Entities
	Our leasing and financing activities require us to use many forms of entities to achieve our business objectives and we have participated to varying degrees in the design and formation of these entities. Our involvement in VIEs varies and includes being a passive investor in the VIE with involvement from other parties, managing and structuring all the activities, and being the sole shareholder of the VIE. See Note 13—Debt for more information related to our borrowing arrangements through subsidiaries that are considered VIEs.
	Non-Recourse Financing Structures
	We consolidate one entity in which we have a variable interest and was established to obtain secured financing for the purchase of aircraft. We have determined that we are the PB of the entity because we control and manage all aspects of the entity, including directing the activities that most significantly affect the economic performance of the entity, and we absorb the majority of the risks and rewards of the entity.
	Wholly-Owned ECA and Ex-Im Financing Vehicles
	We have created certain wholly-owned subsidiaries for the purpose of purchasing aircraft and obtaining financing secured by such aircraft. The secured debt is guaranteed by the European ECAs and the Export-Import Bank of the United States. The entities meet the definition of a VIE because they do not have sufficient equity to operate without subordinated financial support from us in the form of intercompany notes. We control and manage all aspects of these entities, including directing the activities that most significantly affect the entity's economic performance, we absorb the majority of the risks and rewards of these entities and we guarantee the activities of these entities. These entities are therefore consolidated into our Consolidated Financial Statements.
	Other Secured Financings
	We have created a number of wholly-owned subsidiaries for the purpose of obtaining secured financings. The entities meet the definition of a VIE because they do not have sufficient equity to operate without subordinated financial support from us in the form of intercompany notes. We control and manage all aspects of these entities, including directing the activities that most significantly affect the entity's economic performance, we absorb the majority of the risks and rewards of these entities and we guarantee the activities of these entities. These entities are therefore consolidated into our Consolidated Financial Statements.
	Wholly-Owned Leasing Entities
	We have created wholly-owned subsidiaries for the purpose of facilitating aircraft leases with airlines. The entities meet the definition of a VIE because they do not have sufficient equity to operate without subordinated financial support from us in the form of intercompany loans, which serve as equity. We control and manage all aspects of these entities, including directing the activities that most significantly affect the entity's economic performance, we absorb the majority of the risks and rewards of these entities and we guarantee the activities of the entities. These entities are therefore consolidated into our Consolidated Financial Statements.
	Other Variable Interest Entities
	We have variable interests in the following entities, in which we have determined we are not the PB because we do not have the power to direct the activities that most significantly affect the entity's economic performance: (i) one entity that we have previously sold aircraft to and for which we manage the aircraft, in which our variable interest consists of the servicing fee we receive for the management of those aircraft; and (ii) two affiliated entities, Castle Trusts, we sold aircraft to in 2003 and 2004, which aircraft we continue to manage, in which our variable interests consist of the servicing fee we receive for the management of those aircraft.

	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	Fair value is defined as price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. The degree of judgment used in measuring the fair value of financial instruments generally correlates with the level of pricing observability. Assets and liabilities recorded at fair value on our Consolidated Balance Sheets are measured and classified in a hierarchy for disclosure purposes consisting of three levels based on the observability of inputs available in the market place used to measure fair value.

	Level 1—		Quoted prices available in active markets for identical assets or liabilities as of the reported date.

	Level 2—		Fair values estimated using significant other observable inputs.

	Level 3—		Fair value estimates using significant unobservable inputs.
	At December 31, 2013, our derivative portfolio consisted of interest rate swap contracts. The fair value of these instruments was based upon a model that employed current interest and volatility rates, as well as other observable inputs as applicable. As such, the valuation of these instruments was classified as Level 2.
	The following tables summarize our financial assets and liabilities as of December 31, 2014 for Successor and December 31, 2013 for Predecessor that we measured at fair value on a recurring basis by level within the fair value hierarchy. As required by U.S. GAAP, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to their fair value measurement.

	(a)	The balance includes CVA and MVA adjustments of $0.01 million as of December 31, 2013.
	Assets and Liabilities Measured at Fair Value on a Non-recurring Basis
	We applied the acquisition method of accounting and measured the identifiable assets acquired, the liabilities assumed, and non-controlling interest at fair value on the Closing Date. See Note 3—AerCap Transaction.
	We measure the fair value of Flight equipment held under operating leases, when U.S. GAAP requires the application of fair value, including events or changes in circumstances that indicate that the carrying amount of the flight equipment may not be recoverable. We measure the fair value of flight equipment on a non-recurring basis when events or changes in circumstances indicate that the carrying amount of our aircraft may not be recoverable.
	The fair value of flight equipment is classified as a Level 3 valuation. Management evaluates quarterly the need to perform a recoverability assessment of flight equipment, and performs this assessment at least annually for all aircraft in our fleet. Recoverability assessments are performed whenever events or changes in circumstances indicate that the carrying amount of our flight equipment may not be recoverable, which may require us to change our assumptions related to future projected cash flows. Management is active in the aircraft leasing industry and develops the assumptions used in the recoverability assessment. As part of the recoverability process, we update the critical and significant assumptions used in the recoverability assessment. Fair value of flight equipment is determined using an income approach based on the present value of cash flows from contractual lease agreements, flight hour rentals, where appropriate, and projected future lease payments, which extend to the end of the aircraft's economic life in its highest and best use configuration, as well as a disposition value, based on the expectations of market participants.
	We recognized impairment charges and fair value adjustments for the Successor period beginning February 5, 2014 and ending December 31, 2014, the Predecessor period beginning January 1, 2014 and ending May 13, 2014, the Predecessor year ended December 31, 2013, and the Predecessor year ended December 31, 2012 as provided in Note 20—Asset Impairment.
	The following table presents the effect on our Consolidated Financial Statements as a result of the non-recurring impairment charges and fair value adjustments recorded to flight equipment during the Predecessor period beginning January 1, 2014 and ending May 13, 2014:

	(a)	Represents collections and prepaid lease costs applied against the finance and sales-type leases.
	Inputs to Non-Recurring Fair Value Measurements Categorized as Level 3
	We measure the fair value of certain assets and liabilities on a non-recurring basis when U.S. GAAP requires the application of fair value, including events or changes in circumstances that indicate that the carrying amounts of assets may not be recoverable. Assets subject to these measurements include flight equipment. The fair value of flight equipment is estimated when (i) aircraft held for use in our fleet is not recoverable; (ii) aircraft expected to be sold or parted-out is not recoverable; and (iii) aircraft is sold as part of a sales-type lease. We use the income approach to measure the fair value of flight equipment, which is based on the present value of estimated future cash flows. The key inputs to the income approach include the current contractual lease cash flows and the projected future non-contractual lease cash flows, extended to the end of the aircraft's estimated holding period in its highest and best use configuration, as well as a contractual or estimated disposition value. The determination of these key inputs in applying the income approach is discussed below.
	The current contractual lease cash flows are based on the in-force lease rates. The projected future non-contractual lease cash flows are estimated based on the aircraft type, age, and airframe and engine configuration of the aircraft. The projected non-contractual lease cash flows are applied to a follow-on lease term(s), which are estimated based on the age of the aircraft at the time of re-lease. Follow-on leases and related cash flows are assumed through the estimated holding period of the aircraft. The holding period assumption is the period over which future cash flows are assumed to be generated. We generally assume the aircraft will be leased over a 25-year estimated economic useful life from the date of manufacture unless facts and circumstances indicate the holding period is expected to be shorter. Shorter holding periods can result from our assessment of the continued marketability of certain aircraft types or when a potential sale or future part-out of an individual aircraft has been contracted for, or is likely. In instances of a potential sale or part-out, the holding period is based on the estimated or actual sale or part-out date. The disposition value is generally estimated based on aircraft type. In situations where the aircraft will be disposed of, the residual value assumed is based on an estimated part-out value or the contracted sale price.
	The aggregate cash flows, as described above, are then discounted to present value. The discount rate used is based on the aircraft type and incorporates market participant assumptions regarding the market attractiveness of the aircraft type and the likely debt and equity financing components and the required returns of those financing components. Management has identified the key elements affecting the fair value calculation as the discount rate used to present value the estimated cash flows, the estimated aircraft holding period, and the proportion of contractual versus non-contractual cash flows.
	For Flight equipment for which non-recurring impairment charges and fair value adjustments were recorded during the Predecessor period beginning January 1, 2014 and ending May 13, 2014, the following table presents the fair value of such Flight equipment as of the measurement date, the valuation technique, and the related unobservable inputs:

			Predecessor
			Fair Value			Valuation		Unobservable Inputs		Range
			Fair Value			Technique		Unobservable Inputs		(Weighted-Average)
			(Dollars in
millions)
Flight Equipment			$	67.8		Income Approach		Discount Rate		12.0% - 16.5% (13.2%)


							Remaining Holding Period		0 - 8 years (4 years)

							Present Value of Non-Contractual Cash Flows as a Percentage of Fair Value		0 - 100% (55%)
Sensitivity to Changes in Unobservable Inputs
We consider unobservable inputs to be those for which market data is not available and that we developed using the best information available to us related to assumptions market participants use when pricing the asset or liability. Relevant inputs vary depending on the nature of the asset or liability being measured at fair value. The effect of a change in a particular assumption is considered independently of changes in any other assumptions. In practice, simultaneous changes in assumptions may not always have a linear effect on inputs.
The significant unobservable inputs utilized in the fair value measurement of flight equipment are the discount rate, the remaining estimated holding period and the non-contractual cash flows. The discount rate is affected by movements in the aircraft funding markets, and can be impacted by fluctuations in required rates of return in debt and equity, and loan to value ratios. The remaining holding period and non-contractual cash flows represent management's estimate of the remaining service period of an aircraft and the estimated non-contractual cash flows over the remaining life of the aircraft. An increase in the discount rate applied would decrease the fair value of an aircraft, while an increase in the remaining estimated holding period or the estimated non-contractual cash flows would increase the fair value measurement.
Fair Value Disclosures of Financial Instruments
Successor
We used the following methods and assumptions in estimating our fair value disclosures for financial instruments:
Cash and Cash Equivalents: The carrying value reported on the balance sheet for cash and cash equivalents and restricted cash approximates its fair value.
Notes Receivable: The carrying value reported on the balance sheet for notes receivable approximates its fair value.
Debt Financing: The fair value of our debt financings consider the frequency and volume of quoted prices of our debt in active markets, where available. The fair value of our long-term unsecured fixed rate and floating rate debt is estimated using quoted market prices. The fair value of our long-term secured debt is estimated using discounted cash flow analysis based on current market prices for similar type debt.
Derivatives: At December 31, 2014, our derivative portfolio consisted of interest rate swap contracts. Fair values were based on the use of a valuation model that utilizes, among other things, current interest, foreign exchange and volatility rates, as applicable. As such, the valuation of these instruments is classified as Level 2.
Guarantees: Guarantees are included in Accrued expenses, accounts payable and other liabilities on our Consolidated Balance Sheets. Fair value is determined by reference to the underlying aircraft and guarantee amount. See Note 24—Commitments and Contingencies—Asset Value Guarantees.
The carrying amounts and fair values of our most significant financial instruments at December 31, 2014 are as follows:

(a)	Includes restricted cash of $421.2 million as of December 31, 2014.
Predecessor
We used the following methods and assumptions in estimating our fair value disclosures for financial instruments:
Cash and Cash Equivalents: The carrying value reported on the balance sheet for cash and cash equivalents and restricted cash approximated its fair value. We considered time deposits that were not readily available for immediate withdrawal as Level 2 valuations.
Notes Receivable: The fair values for notes receivable were estimated using discounted cash flow analyses, using market quoted discount rates that approximated the credit risk of the issuing party.
Debt Financing: The fair value of our debt financings, including the level within the fair value hierarchy, was determined at the end of each reporting period. We considered the frequency and volume of quoted prices of our debt in active markets, where available, in making our determination. The fair value of our long-term unsecured fixed-rate debt was estimated using a discounted cash flow analysis, based on our spread to U.S. Treasury bonds for similar debt. The fair value of our long-term unsecured floating rate debt was estimated using a discounted cash flow analysis based on credit default spreads. The fair value of our long-term secured debt was estimated using discounted cash flow analysis based on credit default spreads.
Derivatives: Fair values were based on the use of a valuation model that utilizes among other things, current interest, foreign exchange and volatility rates, as applicable.
Guarantees: Guarantees were included in Accrued interest and other payables on our Consolidated Balance Sheets. Fair value was determined by reference to the underlying aircraft fair value and guarantee amount.
The carrying amounts and fair values (as well as the level within the fair value hierarchy to which the valuation relates) of our financial instruments at December 31, 2013 were as follows:

	Successor
	From time to time, we employ a variety of derivatives to manage exposures to interest rate and foreign currency risks. At December 31, 2014, we had interest rate swap agreements maturing through 2015 that the predecessor previously entered into with a subsidiary of AIG.
	All of our interest rate swap agreements are subject to a master netting agreement, which would allow the netting of derivative assets and liabilities in the case of default under any one contract. Our interest rate swap agreements are recorded at fair value on our Consolidated Balance Sheets in Derivative liabilities (see Note 26—Fair Value Measurements). All of our derivatives were in a liability position at December 31, 2014. Our derivative contracts do not have any credit risk related contingent features and we are not required to post collateral under any of our existing derivative contracts.
	As of December 14, 2014 we do not apply hedge accounting and as a result we record changes in market values in income.
	Predecessor
	At December 31, 2013, we had interest rate swap agreements entered into with a related party that matured through 2015. During the year ended December 31, 2013, we also had two interest rate cap agreements with an unrelated counterparty in connection with a secured financing transaction that were scheduled to mature in 2018. We prepaid the debt related to our interest rate cap agreements during the year ended December 31, 2013 and terminated our interest rate cap agreements.
	All our interest rate swap and foreign currency swap agreements have been or were designated as cash flow hedges and changes in fair value of cash flow hedges are recorded in OCI. Where hedge accounting is not achieved, the change in fair value of the derivative is recorded in income. We did not designate the interest rate cap agreements as hedges, and all changes in fair value were recorded in income.
	We have previously de-designated and re-designated certain of our derivative contracts. The balance accumulated in AOCI at the time of the de-designation is amortized into income over the remaining life of the previously hedged item. If the expected cash flows of the previously hedged item are no longer expected to occur, any related amounts remaining in AOCI would be immediately recognized in earnings.
	All of our interest rate swap agreements are subject to a master netting agreement, which would allow the netting of derivative assets and liabilities in the case of default under any one contract. Our interest rate swap agreements are recorded at fair value on our Consolidated Balance Sheets in Derivative liabilities (see Note 26—Fair Value Measurements). All of our derivatives were in a liability position at December 31, 2013. Our derivative contracts do not have any credit risk related contingent features and we are not required to post collateral under any of our existing derivative contracts.
	Derivatives have notional amounts, which generally represent amounts used to calculate contractual cash flows to be exchanged under the contract. The following tables present notional amounts and fair values of derivatives outstanding at the following dates:

Summary of Significant Accounting Policies, Successor (Policies)	12 Months Ended
	Dec. 31, 2014
Summary of significant accounting policies
Principles of Consolidation	Principles of Consolidation: The accompanying consolidated financial statements include the results of all entities in which we have a controlling financial interest, including VIEs for which we are the PB. The PB is the entity that has both (i) the power to direct the activities of the VIE that most significantly affect the entity's economic performance and (ii) the obligation to absorb losses or the right to receive benefits that could be potentially significant to the VIE. See Note 25—Variable Interest Entities.

Use of estimates	Use of estimates: The preparation of Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. For us, the use of estimates is or could be a significant factor affecting acquisition accounting in a business combination, the reported carrying values of flight equipment, intangibles, investments, trade and notes receivable, deferred tax assets and accruals and reserves. Management considers information available from professional appraisers, where possible, to support estimates, particularly with respect to flight equipment. Despite management's best efforts to accurately estimate such amounts, actual results could materially differ from those estimates.

Cash and cash equivalents	Cash and cash equivalents: Cash and cash equivalents include cash and highly liquid investments with an original maturity of three months or less.

Restricted cash	Restricted cash: Restricted cash includes cash held by banks that is subject to withdrawal restrictions. Such amounts are typically restricted under secured debt agreements and can be used only to service the aircraft securing the debt and to make principal and interest payments on the debt

Trade receivables	Trade receivables: Trade receivables represent unpaid, current lessee obligations under existing lease contracts. Allowances are provided for doubtful accounts where the risk of non-recovery is probable. The risk of non-recovery is primarily based on the extent to which amounts outstanding exceed the value of security held, together with an assessment of the financial strength and condition of a debtor and the economic conditions persisting in the debtor's operating environment.

Capitalization of interest	Capitalization of interest: We capitalize interest on Prepayments on flight equipment in respect of flight equipment on forward order and add such amount to Prepayments on flight equipment. The amount of interest capitalized is the actual interest costs incurred on funding specific to the prepayments, if any, or the amount of interest costs which could have been avoided in the absence of such prepayments.

Net investment in finance and sales-type leases	Net investment in finance and sales-type leases: If a lease meets specific criteria under U.S. GAAP, we recognize the lease in Net investment in finance and sales-type leases on our Consolidated Balance Sheets and de-recognize the aircraft from Flight equipment held for operating leases. For sales-type leases, we recognize the difference between the aircraft carrying value and the Net investment in finance and sales-type leases as a gain on sale of assets or an impairment. The amounts recognized for finance and sales-type leases consist of lease receivables and the estimated unguaranteed residual value of the leased flight equipment on the lease termination date, less the unearned income. Expected unguaranteed residual values of leased flight equipment are based on our assessment and independent appraisals of the values of the leased flight equipment at expiration of the lease terms. The unearned income is recognized in Lease revenue on our Consolidated Statements of Operations, over the lease term, in a manner that produces a constant rate of return on the lease.

Maintenance rights intangible and lease premium, net and Other definite-lived intangible assets	Maintenance rights intangible and lease premium, net: The maintenance rights intangible asset arose from the application of the acquisition method of accounting to aircraft and leases which were acquired in the AerCap Transaction and represented the fair value of our contractual aircraft return rights under our leases at the Closing Date. The maintenance rights intangible asset represents the contractual right under our leases to receive the aircraft in a specified maintenance condition at the end of the lease (EOL contracts) or our right to an aircraft in better maintenance condition by virtue of our obligation to contribute towards the cost of the maintenance events performed by the lessee either through reimbursement of maintenance deposit rents held (MR contracts), or through a lessor contribution to the lessee. The maintenance rights represented the difference between the specified maintenance return condition in our leases and the actual physical condition of our aircraft at the Closing Date.
	For EOL contracts, maintenance rights expense is recognized upon lease termination, to the extent the lease end cash compensation paid to us is less than the maintenance rights intangible asset. Maintenance rights expense is included in Leasing expenses in our Consolidated Statements of Operations. To the extent the lease end cash compensation paid to us is more than the maintenance rights intangible asset, revenue is recognized in Lease revenue in our Consolidated Statement of Operations, upon lease termination. For MR contracts, maintenance rights expense is recognized at the time the lessee provides us with an invoice for reimbursement relating to the cost of a qualifying maintenance event that relates to pre-acquisition usage.
	The lease premium represents the value of an acquired lease where the contractual rent payments are above the market rate. We amortize the lease premium on a straight-line basis over the term of the lease as a reduction of Lease revenue.
	Other definite-lived intangible assets: These primarily represent customer relationships recorded at fair value as a result of the AerCap Transaction. The rate of amortization of these definite-lived intangible assets is estimated based on the period over which we expect to derive economic benefits from such assets. The amortization expense is recorded in Depreciation and amortization on our Consolidated Statements of Operations. We evaluate all definite-lived intangible assets for impairment when events or changes in circumstances indicate that an intangible asset value may not be recoverable.

Derivative financial instruments	Derivative financial instruments: We may use derivative financial instruments to manage our exposure to interest rate risks and foreign currency risks. Derivatives are recognized on the balance sheet at their fair value, which includes consideration of the credit rating and risk attaching to the counterparty of the derivative contract. We have considered both the quantitative and qualitative factors when determining our counterparty credit risk. We currently do not apply hedge accounting to our derivatives. Changes in fair value of derivatives are recorded in Interest expense in our Consolidated Statements of Operations.
	Net cash received or paid under derivative contracts in any reporting period is classified as operating cash flows in our Consolidated Statements of Cash Flows.

Fair Value Measurements	Fair Value Measurements: Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We measure the fair value of our derivatives on a recurring basis and measure the fair values of aircraft, investment in finance and sales-type leases and asset value guarantees on a non-recurring basis. See Note 26—Fair Value Measurements.

Other assets	Other assets: Other assets consist of inventory, lease incentives, prepaid expenses, debt issuance costs, notes receivable, other receivables and other tangible fixed assets.
	Inventory consists primarily of engine and airframe parts we sell through our subsidiary, AeroTurbine. Inventory is valued at the lower of cost or market value. Cost is primarily determined using the specific identification method for individual part purchases and on an allocated basis for engines and aircraft purchased for disassembly and for bulk purchases. Costs are allocated using the relationship of the cost of the engine, aircraft, or bulk inventory purchase to the estimated retail sales value at the time of purchase. At the time of sale this ratio is applied to the sales price of each individual part to determine its cost. We periodically evaluate this ratio and, if necessary, update sales estimates and make adjustments to this ratio. Generally, inventory that is held for more than four years is considered excess inventory and its carrying value is reduced to zero.
	We capitalize amounts paid or value provided to lessees as lease incentives. We amortize lease incentives on a straight-line basis over the term of the related lease as a reduction of Lease revenue.
	Notes receivable represent amounts advanced in the normal course of our operations and also arise from the restructuring and deferral of trade receivables from lessees experiencing financial difficulties. Allowances are made for doubtful accounts where the risk of non-recovery is probable. The assessment of the risk of non-recovery where lessees are experiencing financial difficulties is primarily based on the extent to which amounts outstanding exceed the value of security held, together with an assessment of the financial strength and condition of the debtor and the economic conditions persisting in the debtor's operating environment.
	Other tangible fixed assets consist primarily of computer equipment, leasehold improvements and office furniture, and are valued at acquisition cost and depreciated at various rates over the asset's estimated useful life using the straight-line method. Depreciation expense on other tangible fixed assets is recorded in Depreciation and amortization on our Consolidated Statements of Operations.

Accrued maintenance liability	Accrued maintenance liability: Under our aircraft leases, the lessee is responsible for maintenance and repairs and other operating expenses related to our flight equipment during the term of the lease. In certain instances, such as when an aircraft is not subject to a lease, we may incur maintenance and repair expenses for our aircraft. Maintenance and repair expenses are recorded in Leasing expenses in our Consolidated Statements of Operations, to the extent such expenses are incurred by us.
	We may be obligated to make additional payments to the lessee for maintenance related expenses primarily related to usage of major life-limited components existing at the inception of the lease ("lessor maintenance contributions"). For all lease contracts that were not part of the AerCap Transaction, we expense planned major maintenance activities such as lessor maintenance contributions when incurred. The charge is recorded in Leasing expenses in our Consolidated Statements of Operations. In the case we have established an accrual as an assumed liability for such payment in connection with the purchase of an aircraft with a lease attached, such payments are charged against the existing accrual.
	For all contracts outstanding at the Closing Date, we determined the fair value of our maintenance liability, including lessor maintenance contributions, using the present value of the expected cash outflows. The discounted amounts are accreted in subsequent periods to their respective nominal values, up until the expected maintenance event dates, using the effective interest method. The accretion is recorded as an increase to Interest expense in our Consolidated Statements of Operations.

Debt and Deferred Debt Issuance Costs	Debt and Deferred Debt Issuance Costs: Long-term debt is carried at the principal amount borrowed, including unamortized discounts and premiums and fair value adjustments, where applicable. The fair value adjustments reflect the application of the acquisition method of accounting to the debt outstanding on the Closing Date. We amortize the amount of discount or premium and fair value adjustments over the period the debt is outstanding using the effective interest method. The costs we incur for issuing debt are capitalized and amortized as an increase to Interest expense over the life of the debt using the effective interest method.

Lessee Security Deposits	Lessee Security Deposits: On the Closing Date, we discounted our lessee security deposits to their respective present values. We accrete these discounted amounts to their respective nominal values, over the period we expect to refund the security deposits to each lessee, using the effective interest method, recognizing an increase to Interest expense.

Revenue recognition	Revenue recognition: We lease flight equipment principally under operating leases and recognize rental income on a straight-line basis over the life of the lease. At lease inception, we review all necessary criteria to determine proper lease classification. We account for lease agreements that include step rent clauses on a straight-line basis. The difference between rental revenue recognized and the cash received is included in Other assets, and in the event it is a liability in Accrued expenses, accounts payable and other liabilities. In certain cases, leases provide for rentals contingent on usage. The usage may be calculated based on hourly usage or on the number of cycles operated, depending on the lease contract. Revenue contingent on usage is recognized at the time the lessee reports the usage to us.
	Lease agreements for which base rent is based on floating interest rates are included in minimum lease payments based on the floating interest rate existing at the inception of the lease; any increases or decreases in lease payments that result from subsequent changes in the floating interest rate are contingent rentals and are recorded as increases or decreases in Lease revenue in the period of the interest rate change.
	Our lease contracts normally include default covenants, which generally obligate the lessee to pay us damages to put us in the position we would have been in had the lessee performed under the lease in full. There are no additional payments required which would increase the minimum lease payments. We cease revenue recognition on a lease contract when the collectability of such rentals is no longer reasonably assured. For past-due rentals that exceed related security deposits held, which have been recognized as revenue, provisions are established on the basis of management's assessment of collectability. Such provisions are recorded in Selling, general and administrative expenses on the Consolidated Statements of Operations.
	Revenues from Net investment in finance and sales-type leases are included in Lease revenue in our Consolidated Statements of Operations and are recognized using the interest method to produce a constant yield over the life of the lease.
	Most of our lease contracts require payment in advance. Rentals received, but unearned under these lease agreements are recorded as deferred revenue on the balance sheet.
	Under our aircraft leases, the lessee is responsible for maintenance and repairs of our flight equipment and related expenses during the term of the lease. Under the provisions of many of our leases, the lessee is required to make payments of supplemental maintenance rents which are calculated with reference to the utilization of the airframe, engines and other major life-limited components during the lease. We record as revenue all supplemental maintenance rent receipts not expected to be reimbursed to lessees. We estimate the total amount of maintenance reimbursements for the entire lease and only record revenue after we have received enough maintenance rents under a particular lease to cover the total amount of estimated maintenance reimbursements during the remaining lease term. In these leases, upon lessee presentation of invoices evidencing the completion of qualifying maintenance on the aircraft, we make a payment to the lessee to compensate for the cost of the maintenance, up to the maximum of the supplemental maintenance rent payments made with respect to the lease contract.
	In most lease contracts not requiring the payment of supplemental maintenance rents, the lessee is generally required to re-deliver the aircraft in a similar maintenance condition (normal wear and tear excepted) as when accepted under the lease, with reference to major life-limited components of the aircraft. To the extent that such components are redelivered in a different condition than at acceptance, there is generally EOL cash compensation for the difference at redelivery. We recognize receipts of EOL cash compensation as Lease revenue when received to the extent those receipts exceed the EOL contract maintenance rights intangible asset and receipts of EOL compensation as Leasing expenses to the extent those receipts do not exceed EOL contract maintenance intangible asset.
	For all of our MR contracts, any amounts of accrued maintenance liability existing at the end of a lease are released and recognized as Lease revenue at lease termination. When flight equipment is sold, the portion of the accrued maintenance liability which is not specifically assigned to the buyer is released from the balance sheet, net of any Maintenance rights intangible asset balance, and recognized as Net gain on sale of assets as part of the sale of the flight equipment.
	Net gain on sale of assets originates primarily from the sale of aircraft and engines and are recognized when the delivery of the relevant asset is complete and the risk of loss has transferred to the buyer.
	Other income consists of interest income, management fees, lease termination penalties, and inventory part sales. Income from secured loans, notes receivable and other interest bearing instruments is recognized using the effective yield method as interest accrues under the associated contracts. Lease management fees are recognized as income as they accrue over the life of the contract. Income from the receipt of lease termination penalties is recorded at the time cash is received or when the lease is terminated, if collection is reasonably assured.

Share-based compensation	Share-based compensation: Prior to the AerCap Transaction, certain of our employees participated in various AIG share-based compensation plans, and the associated expense reflects costs allocated to us by AIG. Subsequent to the AerCap Transaction, certain employees received AerCap share-based awards, consisting of restricted stock units and restricted stock. The amount of such expense is determined by reference to the fair value of the restricted stock units or restricted stock on the grant date. The share-based compensation expense is recognized over the vesting period using the straight-line method. See Note 22—Employee Benefit Plans and Share-Based and Other Compensation Plans.

Foreign currencies	Foreign currencies: Foreign currency transactions are translated into U.S. dollars at the exchange rate prevailing at the time the transaction took place. Receivables or payables arising from such foreign currency transactions are remeasured into U.S. dollars at the exchange rate on each subsequent balance sheet date. All resulting exchange gains and losses are recorded in Selling, general and administrative expenses on the Consolidated Statements of Operations.

Variable interest entities	Variable interest entities: We consolidate VIEs in which we have determined that we are the PB. We use judgment when determining (i) whether an entity is a VIE; (ii) who are the variable interest holders; (iii) the elements and degree of control that each variable interest holder has; and (iv) ultimately which party is the PB. When determining which party is the PB, we perform an analysis which considers (i) the design of the VIE; (ii) the capital structure of the VIE; (iii) the contractual relationships between the variable interest holders; (iv) the nature of the entities' operations; and (v) the purposes and interests of all parties involved, including related parties. While we consider these factors, our conclusion about whether to consolidate ultimately depends on the breadth of our decision-making ability and our ability to influence activities that significantly affect the economic performance of the VIE. We continually re-evaluate whether we are the PB for VIEs in which we hold a variable interest.

Income Taxes and Deferred income tax assets and liabilities	Income Taxes: We recognize an uncertain tax benefit only to the extent that it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position.
	Deferred income tax assets and liabilities: We report deferred taxes resulting from the temporary differences between the book values and the tax values of assets and liabilities using the liability method. The differences are calculated at nominal value using the enacted tax rate applicable at the time the temporary difference is expected to reverse. Deferred tax assets attributable to unutilized losses carried forward or other timing differences are reduced by a valuation allowance if it is more likely than not that such losses will not be utilized to offset future taxable income.

Reportable segments	Reportable segments: We manage our business and analyze and report our results of operations on the basis of one business segment: leasing, financing, sales and management of commercial aircraft and engines.

Recent Accounting Guidance	Recent Accounting Guidance
	Accounting Standard Adopted during 2014:
	Presentation of Unrecognized Tax Benefits
	In July 2013, the FASB issued an accounting standard that requires a liability related to unrecognized tax benefits to be presented as a reduction to the related deferred tax asset for a net operating loss carryforward or a tax credit carryforward (the "Carryforwards"). When the Carryforwards are not available at the reporting date under the tax law of the jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit will be presented in the financial statements as a liability and will not be combined with the related deferred tax assets. This standard is effective for fiscal years and interim periods beginning after December 15, 2013. Upon adoption, the standard must be applied prospectively to unrecognized tax benefits that exist at the effective date. Predecessor adopted the standard prospectively on January 1, 2014 and reclassed Current income taxes and other tax liabilities of $127.4 million to Deferred income taxes as a result of the adoption.
	Future Application of Accounting Guidance:
	Reporting Discontinued Operations
	In April 2014, the FASB issued an accounting standard that changes the requirements for presenting a component or group of components of an entity as a discontinued operation and requires new disclosures. Under the standard, the disposal of a component or group of components of an entity should be reported as a discontinued operation if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results. Disposals of equity method investments, or those reported as held-for-sale, will be eligible for presentation as a discontinued operation if they meet the new definition. The standard also requires entities to provide specified disclosures about a disposal of an individually significant component of an entity that does not qualify for discontinued operations presentation.
	The standard is effective prospectively for all disposals of components (or classification of components as held for sale) of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods beginning on or after December 15, 2015. Early adoption is permitted, but only for disposals (or classifications of components as held for sale) that have not been reported in financial statements previously issued. We adopted the standard on January 1, 2015, and it did not have a material effect on our consolidated financial condition, results of operations or cash flows.
	Revenue from Contracts with Customers
	In May 2014, the FASB issued an accounting standard that provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The standard will require an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This update creates a five-step model that requires entities to exercise judgment when considering the terms of the contract(s) which include (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue when each performance obligation is satisfied.
	This standard is effective for nonpublic entities for annual periods beginning after December 15, 2017 and interim periods beginning after December 15, 2018. Nonpublic entities are permitted to adopt for annual and interim periods beginning after December 15, 2016. We have the option to apply the provisions of the standard either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of applying this standard recognized at the date of initial application. We plan to early adopt the standard on January 1, 2017. We are evaluating the effect the adoption of the standard will have on our consolidated financial statements.
	Disclosure of Going Concern Uncertainties
	In August 2014, the FASB issued an accounting standard that requires management to assess an entity's ability to continue as a going concern, and to provide related footnote disclosure in certain circumstances. The new standard will be effective for all entities in the first annual period ending after December 15, 2016. Earlier adoption is permitted. We plan to adopt the standard on January 1, 2017.
	Consolidation: Amendments to the Consolidation Analysis
	In February 2015, the FASB issued an accounting standard that affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. Specifically, the amendments modify the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities; eliminate the presumption that a general partner should consolidate a limited partnership; affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds.
	This standard will be effective for annual periods beginning after December 15, 2016 and for interim periods beginning after December 15, 2017 for nonpublic entities. Early adoption is permitted, including adoption in an interim period. The standard may be applied retrospectively or through a cumulative effect adjustment to equity as of the beginning of the year of adoption. We plan to adopt the standard on January 1, 2017. We are evaluating the effect the adoption of the standard will have on our consolidated financial condition, results of operations and cash flows.

Flight Equipment
Summary of significant accounting policies
Flight equipment held for operating leases, net	Flight equipment held for operating leases, net: Flight equipment held for operating leases, including aircraft, is stated at cost less accumulated depreciation and impairment. Flight equipment is depreciated to its estimated residual value using the straight-line method over the assets' useful life, generally 25 years from the date of manufacture, or different period depending on the disposition strategy. The costs of improvements to flight equipment are normally expensed unless the improvement increases the long-term value of the flight equipment or extends the useful life of the flight equipment. The capitalized cost is depreciated over the estimated remaining useful life of the aircraft. The current estimates for residual values for most aircraft types are 15 percent of original manufacture cost, in line with industry standards, except where more recent industry information indicates a different value is appropriate.
	We review estimated useful lives and residual values of aircraft periodically based on our knowledge and external factors coupled with market conditions to determine if they are appropriate and record adjustments to depreciation prospectively on an aircraft by aircraft basis as necessary.
	On a quarterly basis, we evaluate the need to perform a recoverability assessment when events or changes in circumstances indicate that the carrying value of our long-lived assets may not be recoverable. When a recoverability assessment is required, the review for recoverability includes an assessment of the estimated future cash flows associated with the use of an asset and its eventual disposal. The assets are grouped at the lowest level for which identifiable cash flows are largely independent of other groups of assets. In relation to flight equipment on operating lease, the impairment assessment is performed on each individual aircraft, including lease related assets and liabilities. If the sum of the expected undiscounted future cash flows is less than the carrying amount of the asset, an impairment is recognized. The loss is measured as the excess of the carrying amount of the impaired asset over its fair value.
	Fair value reflects the present value of cash expected to be generated from the aircraft in the future, including its expected residual value discounted at a rate commensurate with the associated risk. Future cash flows are assumed to occur under then current market conditions and assume adequate time for a sale between a willing buyer and a willing seller. Expected future lease rates are based on all relevant information available, including current contracted rates for similar aircraft, appraisal data and industry trends.
	Annually, we perform an impairment assessment for all of our aircraft, including a review of the undiscounted cash flows for aircraft 15 years of age, or older, as the cash flows supporting the carrying value of such older aircraft are more dependent upon current lease contracts, which leases are more sensitive to weaknesses in the global economic environment. Deterioration of the global economic environment and a decrease of aircraft values might have a negative effect on the undiscounted cash flows of older aircraft and might trigger impairments.

Summary of significant accounting policies
Principles of Consolidation	Principles of Consolidation: The accompanying consolidated financial statements include the results of all entities in which we have a controlling financial interest, including VIEs for which we are the PB. The PB is the entity that has both (i) the power to direct the activities of the VIE that most significantly affect the entity's economic performance and (ii) the obligation to absorb losses or the right to receive benefits that could be potentially significant to the VIE. See Note 25—Variable Interest Entities.

Variable Interest Entities	Variable interest entities: We consolidate VIEs in which we have determined that we are the PB. We use judgment when determining (i) whether an entity is a VIE; (ii) who are the variable interest holders; (iii) the elements and degree of control that each variable interest holder has; and (iv) ultimately which party is the PB. When determining which party is the PB, we perform an analysis which considers (i) the design of the VIE; (ii) the capital structure of the VIE; (iii) the contractual relationships between the variable interest holders; (iv) the nature of the entities' operations; and (v) the purposes and interests of all parties involved, including related parties. While we consider these factors, our conclusion about whether to consolidate ultimately depends on the breadth of our decision-making ability and our ability to influence activities that significantly affect the economic performance of the VIE. We continually re-evaluate whether we are the PB for VIEs in which we hold a variable interest.

Cash and Cash Equivalents	Cash and cash equivalents: Cash and cash equivalents include cash and highly liquid investments with an original maturity of three months or less.

Restricted Cash	Restricted cash: Restricted cash includes cash held by banks that is subject to withdrawal restrictions. Such amounts are typically restricted under secured debt agreements and can be used only to service the aircraft securing the debt and to make principal and interest payments on the debt

Foreign Currency	Foreign currencies: Foreign currency transactions are translated into U.S. dollars at the exchange rate prevailing at the time the transaction took place. Receivables or payables arising from such foreign currency transactions are remeasured into U.S. dollars at the exchange rate on each subsequent balance sheet date. All resulting exchange gains and losses are recorded in Selling, general and administrative expenses on the Consolidated Statements of Operations.

Investment in finance and sales-type leases	Net investment in finance and sales-type leases: If a lease meets specific criteria under U.S. GAAP, we recognize the lease in Net investment in finance and sales-type leases on our Consolidated Balance Sheets and de-recognize the aircraft from Flight equipment held for operating leases. For sales-type leases, we recognize the difference between the aircraft carrying value and the Net investment in finance and sales-type leases as a gain on sale of assets or an impairment. The amounts recognized for finance and sales-type leases consist of lease receivables and the estimated unguaranteed residual value of the leased flight equipment on the lease termination date, less the unearned income. Expected unguaranteed residual values of leased flight equipment are based on our assessment and independent appraisals of the values of the leased flight equipment at expiration of the lease terms. The unearned income is recognized in Lease revenue on our Consolidated Statements of Operations, over the lease term, in a manner that produces a constant rate of return on the lease.

Capitalized Interest	Capitalization of interest: We capitalize interest on Prepayments on flight equipment in respect of flight equipment on forward order and add such amount to Prepayments on flight equipment. The amount of interest capitalized is the actual interest costs incurred on funding specific to the prepayments, if any, or the amount of interest costs which could have been avoided in the absence of such prepayments.

Deferred Debt Issue Costs and Debt Discounts and Premiums	Debt and Deferred Debt Issuance Costs: Long-term debt is carried at the principal amount borrowed, including unamortized discounts and premiums and fair value adjustments, where applicable. The fair value adjustments reflect the application of the acquisition method of accounting to the debt outstanding on the Closing Date. We amortize the amount of discount or premium and fair value adjustments over the period the debt is outstanding using the effective interest method. The costs we incur for issuing debt are capitalized and amortized as an increase to Interest expense over the life of the debt using the effective interest method.

Derivative Financial Instruments	Derivative financial instruments: We may use derivative financial instruments to manage our exposure to interest rate risks and foreign currency risks. Derivatives are recognized on the balance sheet at their fair value, which includes consideration of the credit rating and risk attaching to the counterparty of the derivative contract. We have considered both the quantitative and qualitative factors when determining our counterparty credit risk. We currently do not apply hedge accounting to our derivatives. Changes in fair value of derivatives are recorded in Interest expense in our Consolidated Statements of Operations.
	Net cash received or paid under derivative contracts in any reporting period is classified as operating cash flows in our Consolidated Statements of Cash Flows.

Fair Value Measurements	Fair Value Measurements: Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We measure the fair value of our derivatives on a recurring basis and measure the fair values of aircraft, investment in finance and sales-type leases and asset value guarantees on a non-recurring basis. See Note 26—Fair Value Measurements.

Income Taxes	Income Taxes: We recognize an uncertain tax benefit only to the extent that it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position.
	Deferred income tax assets and liabilities: We report deferred taxes resulting from the temporary differences between the book values and the tax values of assets and liabilities using the liability method. The differences are calculated at nominal value using the enacted tax rate applicable at the time the temporary difference is expected to reverse. Deferred tax assets attributable to unutilized losses carried forward or other timing differences are reduced by a valuation allowance if it is more likely than not that such losses will not be utilized to offset future taxable income.

Share-based Compensation	Share-based compensation: Prior to the AerCap Transaction, certain of our employees participated in various AIG share-based compensation plans, and the associated expense reflects costs allocated to us by AIG. Subsequent to the AerCap Transaction, certain employees received AerCap share-based awards, consisting of restricted stock units and restricted stock. The amount of such expense is determined by reference to the fair value of the restricted stock units or restricted stock on the grant date. The share-based compensation expense is recognized over the vesting period using the straight-line method. See Note 22—Employee Benefit Plans and Share-Based and Other Compensation Plans.

Summary of significant accounting policies
Principles of Consolidation	Principles of Consolidation: The accompanying consolidated financial statements include the results of all entities in which we have a controlling financial interest, including VIEs for which we are the PB. The PB is the entity that has both (i) the power to direct the activities of the VIE that most significantly affect the entity's economic performance and (ii) the obligation to absorb losses or the right to receive benefits that could be potentially significant to the VIE.

Variable Interest Entities	Variable Interest Entities: We consolidate VIEs in which we have determined that we are the PB. We use judgment when determining (i) whether an entity is a VIE; (ii) who are the variable interest holders; (iii) the elements and degree of control that each variable interest holder has; and (iv) ultimately which party is the PB. When determining which party is the PB, we perform an analysis which considers (i) the design of the VIE; (ii) the capital structure of the VIE; (iii) the contractual relationships between the variable interest holders; (iv) the nature of the entities' operations; and (v) the purposes and interests of all parties involved, including related parties. While we consider these factors, our conclusion about whether to consolidate ultimately depends on the breadth of our decision-making ability and our ability to influence activities that significantly affect the economic performance of the VIE. We continually re-evaluate whether we are the PB for VIEs in which we hold a variable interest.

Lease Revenue	Lease Revenue: We lease flight equipment principally under operating leases and recognize rental revenue on a straight line basis over the life of the lease. The difference between the rental revenue recognized and the cash received under the provisions of our leases is included in Lease receivables and other assets and, in the event it is a liability, in Security deposits, deferred overhaul rental and other customer deposits on our Consolidated Balance Sheets. Past-due rental revenue is recognized on the basis of management's assessment of collectability. Management monitors all lessees that are behind in lease payments and evaluates lessee operational and financial issues to determine the amount of rental revenue to recognize for past due amounts. Our customers are required to make lease payments in advance and we generally recognize rental revenue only to the extent we have received payments or hold security deposits. In certain cases, leases provide for additional flight hour revenue based on usage. The usage may be calculated based on hourly usage or on the number of cycles operated, depending on the lease contract. A cycle is defined as one take-off and landing. The usage is typically reported monthly by the lessee. Rental revenue received under the lease agreements, but unearned, is included in Security deposits, deferred overhaul rental and other customer deposits on our Consolidated Balance Sheets.
	Lease revenues from the rental of flight equipment are reduced by the amortization of lease incentives, which primarily consist of our maintenance contributions to lessees in connection with the lease of used aircraft.
	Under the provisions of our leases, lessees are generally responsible for maintenance and repairs, including major maintenance (overhauls) over the term of the lease. Under the provisions of many of our leases, we receive overhaul rentals based on the usage of the aircraft, calculated based on number of hours or cycles operated. The usage is typically reported monthly by the lessee. For certain airframe and engine overhauls incurred by our lessees, we reimburse the lessee for costs up to, but not exceeding, related overhaul rentals that the lessee has paid to us.
	We recognize overhaul rentals received, net of estimated overhaul reimbursements, as revenue. We estimate expected overhaul reimbursements during the life of the lease, which requires significant judgment. Management determines the reasonableness of the estimated future overhaul reimbursement rate considering quantitative and qualitative information including (i) changes in historical pay-out rates from period to period; (ii) trends in reimbursements made; (iii) trends in historical pay-out rates for expired leases; (iv) future estimates of pay-out rates on leases scheduled to expire in the near term; (v) changes in our business model and portfolio strategies and (vi) other factors affecting the future pay-out rates that may occur from time to time. Changes in the expected overhaul reimbursement estimate result in an adjustment to the cumulative deferred overhaul rental balance sheet amount, which is recognized in current period results. If overhaul reimbursements are different than our estimates, or if estimates of future reimbursements change, there could be a material impact on our results of operations in a given period.
	Additionally, in connection with a lease of a used aircraft, we generally agree to contribute to certain maintenance events the lessee incurs during the lease. At the time we pay the agreed upon maintenance reimbursement, we record the reimbursement against deferred overhaul rentals, to the extent we have received overhaul rentals from the lessee, and against return condition deficiency deposits, to the extent received from the prior lessee. We capitalize as lease incentives any amount of the actual maintenance reimbursement we pay in excess of overhaul rentals paid to us by the lessee and payments received from prior lessees for deficiencies in return conditions and amortize the lease incentives as a reduction of revenues from Rental of flight equipment over the remaining life of the lease.Lease Revenue: We lease flight equipment principally under operating leases and recognize rental revenue on a straight line basis over the life of the lease.

We capitalize as lease incentives any amount of the actual maintenance reimbursement we pay in excess of overhaul rentals paid to us by the lessee and payments received from prior lessees for deficiencies in return conditions and amortize the lease incentives as a reduction of revenues from Rental of flight equipment over the remaining life of the lease.

Capitalized Major Maintenance Costs	Capitalized Major Maintenance Costs: When an aircraft is repossessed or when a lessee defaults on its lease obligations, we may be required to perform major maintenance on the aircraft. In these instances, if we have not received sufficient overhaul rentals under the lease, we capitalize the costs of the overhaul, to the extent that those costs meet the recognition criteria of an asset, and amortize those costs over the period until the next estimated overhaul event.

Return Condition Payments	Return Condition Payments: We may receive payments from our lessees at the conclusion of a lease, rather than requiring them to make the required repairs to meet return conditions. These return condition payments are generally negotiated to facilitate an efficient return of the aircraft, which generally results in the aircraft being delivered to the next lessee in a condition less than anticipated during the lease negotiations. The return condition payments are initially recognized as a liability in Security deposits, deferred overhaul rental and other customer deposits on our Consolidated Balance Sheets.

Lease Incentive Costs	Lease Incentive Costs: We capitalize as lease incentives any amounts paid by us to lessees or other parties in connection with the lease transactions. These amounts include the actual maintenance reimbursement we pay in excess of overhaul rentals and payments received from prior lessees for deficiencies in return conditions and lessee-specific aircraft cabin modifications. We amortize the lease incentives as a reduction of revenues from Rental of flight equipment over the remaining life of the lease.

Flight Equipment Marketing and Gain on Aircraft Sales	Flight Equipment Marketing and Gain on Aircraft Sales: Flight equipment marketing and gain on aircraft sales consists of commissions generated from the leasing and sales of managed aircraft and gains generated from the sale of flight equipment. Flight equipment sales are recognized when substantially all of the risks and rewards of ownership have passed to the new owner. Retained lessee obligations, if any, are recognized as reductions to Flight equipment marketing and gain on aircraft sales at the time of the sale.

Cash and Cash Equivalents	Cash and Cash Equivalents: We consider cash and cash equivalents with original maturity dates of 90 days or less to be cash on hand and highly liquid investments. At December 31, 2013, cash and cash equivalents consisted of cash on hand and time deposits.

Restricted Cash	Restricted Cash: All cash unavailable for use in our operations is considered restricted cash. Such amounts are typically restricted under secured debt agreements and can be used only to service the aircraft securing the debt and to make principal and interest payments on the debt.

Foreign Currency	Foreign Currency: Assets and liabilities denominated in foreign currencies are translated into US dollars using the exchange rates at the balance sheet date. Foreign currency transaction gains or losses are translated into US dollars using the average exchange rate during the period.

Flight Equipment	Flight Equipment: Flight equipment is stated at cost. Purchases, major additions and modifications and interest on deposits during the construction phase are capitalized. We generally depreciate aircraft using the straight-line method over a 25-year life from the date of manufacture to an estimated residual value. At times, management may change useful lives or residual values of certain aircraft, as appropriate. Any such changes are accounted for on a prospective basis. As of December 31, 2013, 104 of our aircraft, with a net book value of $1.1 billion, are being depreciated over useful lives of less than 25-years from the date of manufacture. The weighted average useful life of these aircraft, weighted by the net book value of such aircraft, is 16.9 years.

Vendor Payments	Vendor Payments: As part of the purchase of new aircraft, aircraft engines and related equipment, we will often obtain payments from our vendors in the form of cash and other consideration ("vendor payments"). Generally, vendor payments are recognized as a reduction in the purchase price of aircraft, unless facts and circumstances indicate that the vendor payment was provided as compensation for a service provided by us or as a reimbursement of costs incurred by us to sell the vendor's products.

Impairments on Flight Equipment Held for Use and Flight Equipment Held for Sale	Impairments on Flight Equipment Held for Use: Management evaluates quarterly the need to perform a recoverability assessment of held for use aircraft considering the requirements under GAAP and performs this assessment at least annually for all aircraft in our fleet. Recoverability assessments are performed whenever events or changes in circumstances indicate that the carrying amount of our aircraft may not be recoverable. Some of these events or changes in circumstances may include potential disposals of aircraft (sales or part-outs), changes in contracted lease terms, changes in the lease status of an aircraft (leased, re-leased, or not subject to lease), repossessions of aircraft, changes in portfolio strategies, changes in demand for a particular aircraft type and changes in economic and market circumstances. Economic and market circumstances include the risk factors affecting the airline industry. Any of these events would be considered when it occurs before the financial statements are issued, including lessee bankruptcies occurring subsequent to the balance sheet date.
	Recoverability of an aircraft's carrying amount is measured by comparing the carrying amount of the aircraft to the estimated future undiscounted cash flows expected to be generated by the aircraft. The undiscounted cash flows used in the recoverability assessment include the current contractual lease cash flows and projected future non-contractual lease cash flows, both of which include estimates of net overhaul rental collections, where appropriate, extended to the end of our estimated holding period, and an estimated disposition value for each aircraft. If the future undiscounted cash flows are less than the aircraft carrying amount, the aircraft is impaired and is re-measured to fair value in accordance with our Fair Value Policy. The difference between the fair value and the carrying amount of the aircraft is recognized as an impairment loss separately in our Consolidated Statements of Operations. Management is active in the aircraft leasing industry and develops the assumptions used in the recoverability assessment.
	As part of our recurring recoverability assessment process, we update the critical and significant assumptions used in the recoverability assessment, including projected lease rates and terms, estimated net overhaul rental collections, residual values, and estimated aircraft holding periods. In updating these critical and significant assumptions, we consider (i) current and future expectations of the global demand for a particular aircraft type; (ii) the impact of fuel price volatility and higher average fuel prices; (iii) the growing impact of new technology aircraft; (iv) the higher production rates sustained by manufacturers of more fuel-efficient newer generation aircraft during the recent economic downturn; (v) the unfavorable impact of low rates of inflation on aircraft values; (vi) current market conditions and industry outlook for future marketing of older mid-generation aircraft and aircraft that are out of production; (vii) decreasing number of lessees for older aircraft; (viii) end-of-life management capabilities provided by our subsidiary, AeroTurbine; and (ix) events occurring subsequent to our balance sheet date that affect the value of our fleet.
	Flight Equipment Held for Sale: We classify aircraft as Flight equipment held for sale when all the criteria under GAAP are met. Such amounts are included in Lease receivables and other assets on our Consolidated Balance Sheets. Aircraft classified as Flight equipment held for sale are recognized at the lower of their carrying amount or estimated fair value less estimated costs to sell. If the carrying amount of the aircraft exceeds its estimated fair value, then a fair value adjustment is recognized separately in our Consolidated Statements of Operations.
	Management uses judgment in evaluating these criteria. Due to the significant uncertainties of potential sale transactions, the held for sale criteria generally will not be met unless the aircraft is subject to a signed sale agreement or management has made a specific determination and obtained appropriate approvals to sell a particular aircraft or group of aircraft. At the time aircraft are classified as Flight equipment held for sale, we cease recognizing depreciation expense.
	We designate an aircraft for part-out when the aircraft is subject to an executed consignment agreement. At that time, we reclassify the aircraft from Flight equipment to Lease receivables and other assets at the lower of its carrying amount or estimated fair value less estimated costs to sell. At the time aircraft are classified as Lease receivables and other assets, the cost and accumulated depreciation are removed from Flight equipment.

Investment in finance and sales-type leases	Investment in finance and sales-type leases: If a lease meets specific criteria under GAAP at the inception of the lease, we recognize the lease in Net investment in finance and sales-type leases on our Consolidated Balance Sheets. For sales-type leases, we de-recognize the aircraft and any lease-related assets or liabilities from our Consolidated Balance Sheets and recognize the difference between the aircraft carrying value, including the lease-related assets or liabilities, and the Net investment in finance and sales-type leases as a gain or loss in our Consolidated Statements of Operations. The amounts recognized for finance and sales-type leases consist of lease receivables and the estimated unguaranteed residual value of the leased flight equipment on the lease termination date, less the unearned income. The unearned income is recognized as Other income in our Consolidated Statements of Operations over the lease term in a manner that produces a constant rate of return on the lease.

Allowance for Credit Losses	Allowance for Credit Losses: An allowance for credit losses is established if it is probable that we will be unable to collect all amounts due according to the original contractual terms of the finance and sales-type receivables and notes receivable ("financing receivables"). Financing receivables consist of net investment in finance and sales-type leases recognized as the gross investment in the lease, less unearned income, and notes receivable recognized at cost. The allowance for credit losses is reported as a reduction of the financing receivables carrying value on the Consolidated Balance Sheets. Additions to the allowance for credit losses are recognized in our Consolidated Statements of Operations in Selling, general and administrative expenses.
	Collectability of financing receivables is evaluated periodically on an individual note and customer level. Financing receivables are considered impaired when we determine that it is probable that we will not be able to collect all amounts due according to the original contractual terms. Individual credit exposures are evaluated based on the realizable value of any collateral, and payment history. The estimated recoverable amount is the value of the expected future cash flows, including amounts that may be realized from the value of the collateral. Allowances for specific credit losses are established for the difference between the carrying amount and the estimated recoverable amount. The accrual of interest income based on the original terms of the financing receivable is discontinued based on the facts and circumstances of the individual credit exposure, and any future interest income is recognized based on cash receipts. Any subsequent changes to the amounts and timing of the expected future cash flows compared with the prior estimates result in a change in the allowance for credit losses and are charged or credited to Selling, general and administrative expense. An allowance is generally reversed only when cash is received in accordance with the original contractual terms of the note. A write-off of the financing receivable is made when recoverability has been abandoned or amounts have been forgiven. Write-offs are charged against previously established allowances for credit losses. Partial or full recoveries of amounts previously written off are credited to the provision for credit loss.
	We also evaluate other receivables from customers periodically for collectability on an individual customer level. Allowances for specific credit losses are established for the difference between the carrying amount and the estimated recoverable amount. A write-off of other receivables is made when recoverability has been abandoned or amounts have been forgiven. Write-offs are charged against previously established allowances for credit losses. Partial or full recoveries of amounts previously written off are credited to the provision for credit loss.

Capitalized Interest	Capitalized Interest: We borrow funds to finance progress payments for the construction of flight equipment ordered and capitalize the interest incurred on such borrowings in the cost of the flight equipment. This amount is calculated using our composite borrowing rate.

Deferred Debt Issue Costs and Debt Discounts and Premiums	Deferred Debt Issue Costs and Debt Discounts and Premiums: The costs we incur for issuing debt are capitalized and amortized as an increase to interest expense over the life of the debt using the effective interest method. If we issue debt at a discount or premium, we amortize the amount of discount or premium over the life of the debt using the effective interest method.

Derivative Financial Instruments	Derivative Financial Instruments: From time to time, we may employ a variety of derivative financial instruments to manage our exposure to interest rate risks and foreign currency risks. Derivatives are recognized on our Consolidated Balance Sheets at fair value. AIG Markets, Inc., a related party, is the counterparty to all our interest rate swaps and foreign currency swaps. We apply either fair value or cash flow hedge accounting when transactions meet specified criteria for hedge accounting treatment. If the derivative does not qualify for hedge accounting, the change in fair value of the derivative is immediately recognized in earnings. If the derivative qualifies for hedge accounting and is designated and documented as a hedge, changes in the fair value of the hedge are either recognized in income along with changes in the fair value of the item being hedged for fair value hedges, or recognized in OCI to the extent the hedge is effective for cash flow hedges. We have elected to classify the cash flows from derivative instruments that have been designated as fair value or cash flow hedges in accordance with GAAP in the same category as the cash flows from the items being hedged.
	At the time the derivative is designated as a hedge, we formally document the relationship between the hedging instrument and hedged item including risk management objectives and strategies for undertaking the hedge transactions. This includes linking the derivative designated as a fair value, a cash flow, or a foreign currency hedge to a specific asset or liability on the balance sheet. We also assess, both at the hedge's inception and on an ongoing basis, whether the hedge has been and is expected to be highly effective in offsetting changes in the fair value or cash flow of hedged item. We use the "hypothetical derivative method" when we assess the effectiveness of a hedge. When it is determined that a hedge has ceased to be highly effective as a hedge, we discontinue hedge accounting.
	We discontinue hedge accounting prospectively when (i) we determine that the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item; (ii) the derivative expires or is sold, terminated, or exercised; or (iii) management determines that designating the derivative as a hedging instrument is no longer appropriate.
	In all situations in which hedge accounting is discontinued and the derivative remains outstanding, we carry the derivative at its fair value on the balance sheet, recognizing changes in the fair value in current-period earnings. The remaining balance in AOCI at the time we discontinue hedge accounting for cash flow hedges is amortized into income over the remaining life of the previously hedged item. If the expected cash flows of the previously hedged item are no longer expected to occur, any related amounts remaining in AOCI would be immediately recognized in earnings.

Inventory	Inventory: Our inventory consists primarily of engine and airframe parts and rotable and consumable parts and is included in Lease receivables and other assets on our Consolidated Balance Sheets. We value our inventory at the lower of cost or market. Cost is primarily determined using the specific identification method for individual part purchases and on an allocated basis for engines and aircraft purchased for disassembly and for bulk inventory purchases. Costs are allocated using the relationship of the cost of the engine, aircraft or bulk inventory purchase to the estimated retail sales value at the time of purchase. At the time of sale, this ratio is applied to the sales price of each individual part to determine its cost. We periodically evaluate this ratio and, if necessary, update sales estimates and make adjustments to this ratio. Generally, inventory that is held for more than four years is considered excess inventory and its carrying value is reduced to zero.

Goodwill and Other Acquired Intangible Assets	Goodwill and Other Acquired Intangible Assets: As a result of our acquisition of AeroTurbine, we recognized goodwill and other intangible assets. Goodwill represents the excess of the cost of the acquired business over the fair value of identifiable assets acquired. Goodwill is not amortized, but is subject to impairment testing annually or more often when events or circumstances indicate that it is more likely than not it is impaired. We amortize the cost of other acquired intangible assets over their estimated useful lives on a straight-line basis. Amortizable intangible assets are tested for impairment based on undiscounted cash flows and, if impaired, written down to fair value based on discounted cash flows. Goodwill and other acquired intangible assets are included in Lease receivables and other assets on our Consolidated Balance Sheets.

Other Comprehensive Income (Loss)	Other Comprehensive Income (Loss): We report gains and losses associated with changes in the fair value of derivatives designated as cash flow hedges and unrealized gains and losses on marketable securities classified as "available-for-sale" in comprehensive income or loss.

Guarantees	Guarantees: In limited cases, we have previously contracted to provide aircraft asset value guarantees to financial institutions and other third parties for a fee. We recognize the guarantee fee paid to us in Accrued interest and other payables on our Consolidated Balance Sheets. The fee received is amortized into Flight equipment marketing and gain on aircraft sales in our Consolidated Statements of Operations over the guarantee period. When it becomes probable that we will be required to perform under a guarantee, we cease recognition of the guarantee fee income and accrue a liability based on an estimate of the loss we will incur to perform under the guarantee. The provision for losses on aircraft asset value guarantees represents changes made in the current period based on our estimate of the losses on asset value guarantees that are probable of being exercised. We reverse the liability only when it is no longer probable that we will incur a loss.

Fair Value Measurements	Fair Value Measurements: Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We measure the fair value of our derivatives on a recurring basis and measure the fair values of aircraft, investment in finance and sales-type leases and asset value guarantees on a non-recurring basis.

Income Taxes	Income Taxes: ILFC is included in the consolidated federal income tax return of AIG as well as certain state tax returns where AIG files on a combined/unitary basis. Our provision for federal income taxes is calculated on a separate return basis, adjusted to give recognition to the effects of net operating losses, foreign tax credits and other tax benefits to the extent we estimate that they would be realizable in AIG's consolidated federal income tax return. Under our tax sharing agreement with AIG, we settle our current tax liability as if ILFC and its subsidiaries are each a separate standalone taxpayer. Thus, AIG credits us to the extent our net operating losses, foreign tax credits and other tax benefits (calculated on a separate return basis) are used in AIG's consolidated tax return and charges us to the extent of our tax liability (calculated on a separate return basis). To the extent the benefit of a net operating loss is not utilized in AIG's consolidated federal income tax return, AIG reimburses us upon the expiration of the loss carry-forward period as long as we are still included in AIG's consolidated federal income tax return and the benefit would have been utilized if we had filed a separate consolidated federal income tax return. Our provision for state income taxes includes California, in which we file with AIG using the unitary apportionment factors, and certain other states, in which we file separate tax returns.
	We calculate our provision for income taxes using the asset and liability method. This method considers the future tax consequences of temporary differences between the financial reporting and the tax basis of assets and liabilities measured using currently enacted tax rates. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
	We recognize an uncertain tax benefit only to the extent that it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position.

Share-based Compensation	Share-based Compensation: We participate in AIG's share-based payment and liability award programs and our share of the calculated costs is allocated to us by AIG. Compensation expense is recognized over the period during which an employee is required to provide service in exchange for the share-based payment.

[1]	We recorded an increase of $296, net of tax of $161, in connection with settlement of the AIG Non-Qualified Income Plan liability, and a decrease of $233 for adjustments to state taxes payable.
[2]	We recorded $10,053 during 2013 and $2,636 during 2012 in Paid-in capital for compensation expenses, legal expenses and other expenses paid by AIG on our behalf for which we were not required to reimburse. Additionally, we recorded $16,690, net of tax of $9,211, in Paid-in capital during 2012 when AIG contributed a corporate aircraft to us.
[3]	The decrease to Retained earnings during the period beginning January 1, 2014 and ending May 13, 2014, included a special distribution of $600,000, which ILFC was required to pay to AIG prior to the completion of the AerCap Transaction in accordance with the Share Purchase Agreement. See Note 3bAerCap Transaction. The special distribution was recorded in Retained earnings as a dividend.
[4]	The increase to Retained earnings during the period beginning January 1, 2014 and ending May 13, 2014, reflects a $9,626 receipt from AIG for certain expected separate company tax liabilities, as required under the AerCap sales agreement, partially offset by decreases in Retained earnings of $5,298, net of tax of $2,889, to record a non-cash dividend reflecting the difference between the proceeds received and the net carrying value of a corporate aircraft sold to AIG, and $1,370 recorded as a dividend, for a fee ILFC paid on behalf of AIG to satisfy a statutory law requirement.
[5]	In 2013, we transferred shares of AIG stock with a carrying value, net of tax, of $0.9 million to AIG and recorded the transaction as a decrease to Retained earnings. In 2012, we recorded a decrease to Retained earnings of $25,379, net of tax of $11,866 when we transferred two corporate aircraft to AIG, and an increase to Retained earnings of $(4) for other miscellaneous adjustments.

[1]	The increase to Retained earnings during the period beginning January 1, 2014 and ending May 13, 2014, reflects a $9,626 receipt from AIG for certain expected separate company tax liabilities, as required under the AerCap sales agreement, partially offset by decreases in Retained earnings of $5,298, net of tax of $2,889, to record a non-cash dividend reflecting the difference between the proceeds received and the net carrying value of a corporate aircraft sold to AIG, and $1,370 recorded as a dividend, for a fee ILFC paid on behalf of AIG to satisfy a statutory law requirement.
[2]	In 2013, we transferred shares of AIG stock with a carrying value, net of tax, of $0.9 million to AIG and recorded the transaction as a decrease to Retained earnings. In 2012, we recorded a decrease to Retained earnings of $25,379, net of tax of $11,866 when we transferred two corporate aircraft to AIG, and an increase to Retained earnings of $(4) for other miscellaneous adjustments.
[3]	We recorded an increase of $296, net of tax of $161, in connection with settlement of the AIG Non-Qualified Income Plan liability, and a decrease of $233 for adjustments to state taxes payable.
[4]	We recorded $10,053 during 2013 and $2,636 during 2012 in Paid-in capital for compensation expenses, legal expenses and other expenses paid by AIG on our behalf for which we were not required to reimburse. Additionally, we recorded $16,690, net of tax of $9,211, in Paid-in capital during 2012 when AIG contributed a corporate aircraft to us.

[1]	The decrease to Retained earnings during the period beginning January 1, 2014 and ending May 13, 2014, included a special distribution of $600,000, which ILFC was required to pay to AIG prior to the completion of the AerCap Transaction in accordance with the Share Purchase Agreement. See Note 3bAerCap Transaction. The special distribution was recorded in Retained earnings as a dividend.
[2]	The increase to Retained earnings during the period beginning January 1, 2014 and ending May 13, 2014, reflects a $9,626 receipt from AIG for certain expected separate company tax liabilities, as required under the AerCap sales agreement, partially offset by decreases in Retained earnings of $5,298, net of tax of $2,889, to record a non-cash dividend reflecting the difference between the proceeds received and the net carrying value of a corporate aircraft sold to AIG, and $1,370 recorded as a dividend, for a fee ILFC paid on behalf of AIG to satisfy a statutory law requirement.
[3]	In 2013, we transferred shares of AIG stock with a carrying value, net of tax, of $0.9 million to AIG and recorded the transaction as a decrease to Retained earnings. In 2012, we recorded a decrease to Retained earnings of $25,379, net of tax of $11,866 when we transferred two corporate aircraft to AIG, and an increase to Retained earnings of $(4) for other miscellaneous adjustments.
