We consolidate all companies in which we have effective control and all variable interest entities (“VIEs”) for which we are deemed the Primary Beneficiary (“PB”) under Accounting Standards Codification (“ASC”) 810. All intercompany balances and transactions with consolidated subsidiaries are eliminated. The results of consolidated entities are included from the effective date of control or, in the case of VIEs, from the date that we are or become the PB. The results of subsidiaries sold or otherwise deconsolidated are excluded from the date that we cease to control the subsidiary or, in the case of VIEs, when we cease to be the PB. Our Consolidated Financial Statements are stated in U.S. dollars, which is our functional currency. Due to rounding, numbers presented throughout this document may not add up precisely to the totals provided and percentages may not precisely reflect the absolute figures. 2. Basis of presentation (continued) 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. 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, intangible assets, investment in finance leases, net, investments, trade receivables and notes receivable, deferred tax assets, income tax accruals and maintenance liabilities. Actual results may differ from our estimates under different conditions, sometimes materially. Risk and Uncertainties In the normal course of business, we encounter several significant types of economic risk, including credit risk, market risk and risks associated with exposure to the aviation industry. Credit risk is the risk of a lessee’s inability or unwillingness to make contractually required payments and to fulfill its other contractual obligations. Market risk reflects the change in the value of financings due to changes in interest rate spreads or other market factors, including the value of collateral underlying financings. Risks associated with exposure to the aviation industry include the risk of a downturn in the commercial aviation industry, which could adversely impact lessee ability to make payments, increase the risk of unscheduled lease terminations and depress lease rates and the value of the Company’s flight equipment. The Covid-19 pandemic continues to pose a range of risks to our business. The emergence of new variants, developments in the public health situation, the reimposition or continuation of travel restrictions, and other pandemic-related complications could have a negative impact on our business. We face significant competition and our business may be adversely affected if market participants change as a result of restructuring or bankruptcies, mergers and acquisitions, or new entities entering or exiting the industry. After a sustained period of relatively low inflation rates, current rates of inflation are above or near recent historical highs in the United States, the European Union, the United Kingdom, and other countries. High rates of inflation may have a number of adverse effects on our business. Inflation may increase the costs of goods, services and labor used in our operations, thereby increasing our expenses. Increased global inflation has contributed to rising interest rates, which may affect our lease revenues, our interest expense, the market value of our interest rate derivatives, and the market value of our flight equipment. We are exposed to geopolitical, economic and legal risks associated with the international operations of our business and those of our lessees, including many of the economic and political risks associated with emerging markets. We are exposed to concentrated political and economic risks in certain geographical regions in which our lessees are concentrated. The Russian invasion of Ukraine and the impact of resulting sanctions by the United States, the European Union, the United Kingdom and other countries has adversely affected and may continue to affect our business and financial condition, results and cash flows.

Accounting Policies [Abstract]
Summary of significant accounting policies	Summary of significant accounting policies Cash and cash equivalents Cash and cash equivalents include cash and highly liquid investments with original maturities 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 maintain the aircraft securing the debt and to provide debt service payments of principal and interest. Trade receivables Trade receivables represent unpaid, current lessee rental obligations under existing lease contracts. Flight equipment held for operating leases, net Flight equipment held for operating leases is stated at cost less accumulated depreciation and impairment. Flight equipment is depreciated to its estimated residual value on a straight-line basis over the useful life of the asset. The costs of improvements to flight equipment are normally recorded as leasing expenses unless the improvement increases the long-term value of the flight equipment. In that case, the capitalized improvement cost is depreciated over the estimated remaining useful life of the asset. Useful Life (a) Residual Value (b) Passenger aircraft 25 years 15 % Freighter aircraft 35 years 15 % Helicopters 30 years 20 % Engines 20 years 60 % (a) Useful life may be determined to be a different period depending on the disposition strategy. (b) Estimated industry price, except where more relevant information indicates that a different residual value is more appropriate. We periodically review the estimated useful lives and residual values of our flight equipment based on our industry knowledge, external factors, such as current market conditions, and changes in our disposition strategies, to determine if they are appropriate, and record adjustments to depreciation rates prospectively on an individual asset basis, as necessary. We test flight equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. The quarterly impairment assessments are primarily triggered by potential sale transactions, leasing transactions, early terminated leases, credit events impacting lessees or forecasted significant and permanent declines in the demand for asset types. The quantitative impairment test is performed at the lowest level for which identifiable cash flows are largely independent of other groups of assets, which is the individual asset, including the lease-related assets and liabilities of that asset, such as the maintenance rights assets, lease incentives, and maintenance liabilities (the “Asset Group”). If the sum of the expected undiscounted future cash flows is less than the Asset Group, an impairment loss is recognized. The loss is measured as the excess of the carrying value of the Asset Group over its estimated fair value. Fair value reflects the present value of future cash flows expected to be generated from the assets, including its expected residual value, discounted at a rate commensurate with the associated risk. Future cash flows are assumed to occur under 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 assets and industry trends. On an annual basis, we also perform an assessment of all assets older than five years and held for operating leases to identify potential impairment by reference to estimated future cash flows at the Asset Group level, and perform a quantitative impairment test. We apply significant judgment in assessing whether an impairment is necessary and in estimating significant input assumptions including the future lease rates, maintenance cash flow forecasts, the residual value and the discount rate when performing quantitative impairment tests. During the lease term, our leases require that the lessee maintain our flight equipment and either provide periodic maintenance rental payments during the lease or provide EOL compensation payments based on the maintenance usage of the flight equipment. In addition, upon lease expiry, the flight equipment undergoes inspection to verify compliance with lease return conditions. We believe that the requirement that the lessee compensate us for the maintenance usage of the flight equipment and our emphasis on maintenance and inspection helps preserve residual values and generally helps us to recover our investment in our leased flight equipment. Capitalization of interest We capitalize interest on prepayments of forward order flight equipment and add such amounts to prepayments on flight equipment. The amount of interest capitalized is the amount of interest costs which could have been avoided in the absence of such prepayments. Investment in finance, sales-type and leveraged leases, net (“Investment in finance leases, net”) Finance leases include direct financing leases, sales-type leases and leveraged leases. If a lease meets specific criteria under U.S. GAAP, we recognize the lease in investment in finance leases, net in our Consolidated Balance Sheets and de-recognize the asset from flight equipment held for operating lease. For sales-type leases, we recognize the difference between the asset carrying value and the amount recognized in investment in finance leases, net in net gain on sale of assets in our Consolidated Income Statements. The amounts recognized for finance and sales-type leases consist of lease receivables and the estimated unguaranteed residual value of the flight equipment on the lease termination date, less the unearned income and net of the allowance for credit losses. Expected unguaranteed residual values are based on our assessment of the values of the flight equipment and, if applicable, the estimated EOL payments expected at the expiration of the lease. The unearned income is recognized as lease revenue over the lease term, using the interest method to produce a constant yield over the life of the lease. Finance leases that are mainly financed at commencement with non-recourse borrowings and that meet certain criteria are accounted for as leveraged leases. Leveraged leases are recorded at the aggregate of rentals receivable, net of that portion of the rental applicable to principal and interest on the non-recourse debt, plus the estimated residual value of the leased asset less unearned income. Unearned income is recognized as lease interest income at a level rate of return on the leveraged lease net investment. Definite-lived intangible assets We recognize intangible assets acquired in a business combination at fair value on the date of acquisition. Amortization of definite-lived intangible assets is either event-driven or is at a rate based on the period over which we expect to derive economic benefits from such assets. Maintenance rights and lease premium, net Maintenance rights assets are recognized when we acquire flight equipment subject to existing leases. These assets represent the contractual right to receive the aircraft in a specified maintenance condition at the end of the lease under lease contracts with EOL payment provisions, or our right to receive the aircraft in better maintenance condition due to aircraft maintenance events performed by the lessee either through reimbursement of maintenance deposit rents held under lease contracts with maintenance reserve provisions, or through a lessor contribution to the lessee. For leases with EOL maintenance provisions, upon lease termination, we recognize receipt of EOL cash compensation as lease revenue to the extent those receipts exceed the EOL maintenance rights asset, and we recognize leasing expenses when the EOL maintenance rights asset exceeds the EOL cash received. For leases with maintenance reserve payment provisions, we recognize maintenance rights expense at the time the lessee submits a reimbursement claim and provides the required documentation related to the cost of a qualifying maintenance event that relates to pre-acquisition usage. Lease premium assets represent the value of an acquired lease where the contractual rental payments are above the market rate. We amortize the lease premium assets on a straight-line basis over the term of the lease as a reduction of lease revenue. Other definite-lived intangible assets, net Other definite-lived intangible assets primarily consist of customer relationships recorded at fair value when we acquired International Lease Finance Corporation (“ILFC”). Intangible assets are amortized over the period during which we expect to derive economic benefits from such assets. The amortization expense is recorded in depreciation and amortization. We evaluate definite-lived intangible assets for impairment when events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. Associated companies Unconsolidated investments where we do not have a controlling financial interest, but over which we have significant influence, are accounted for using the equity method of accounting. Under the equity method of accounting, we recognize our share of earnings and losses based on our ownership percentage of such investments in equity in net earnings (losses) of investments accounted for under the equity method in our Consolidated Income Statements. The carrying amount of the equity method investment is included in Associated companies on our Consolidated Balance Sheets. Refer to Note 11— Associated companies for further details. Distributions received from equity method investees are classified using the cumulative earnings approach. Under this approach, distributions received are considered returns on investment and are classified as cash inflows from operating activities, unless the cumulative distributions received, less distributions received in prior periods that were determined to be returns of investment, exceed cumulative equity in earnings recognized. When such an excess occurs, the current-period distribution up to this excess is deemed to be a return of investment, and is classified as cash inflows from investing activities. Other assets Other assets consist of debt issuance costs, lease incentives, loans receivable, notes receivable, operating lease right-of-use (“ROU”) assets, derivative assets, other tangible fixed assets, straight-line rents, prepaid expenses, inventory, investments and other receivables. Lease incentives 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 Notes receivable primarily arise from the restructuring and deferral of trade receivables from lessees experiencing financial difficulties. Loans Loans are classified as held for investment (“HFI”) when the Company has the intent and ability to hold the loan for the foreseeable future or until maturity. Loans classified as HFI are recorded at amortized cost. Loan origination fees and certain direct origination costs are deferred and recognized as adjustments to interest income over the contractual lives of the related loans. If we no longer have the intent and ability to hold a loan for the foreseeable future, then the loan is transferred to assets held for sale (“HFS”) at the lower of carrying value or estimated fair value less costs to sell. Once classified as HFS, the amount by which the carrying value exceeds fair value is recognized in our Consolidated Income Statements as an impairment loss. In a purchase and leaseback transaction where the seller/lessee effectively retains control of the flight equipment asset, the purchase and leaseback is accounted for as a loan financing. Derivative financial instruments We use derivative financial instruments to manage our exposure to interest rate risks. Derivatives are carried in our Consolidated Balance Sheets at fair value. When cash flow hedge accounting treatment is applied, the changes in fair values related to the effective portion of the derivatives are recorded in accumulated other comprehensive income (loss) (“AOCI”), and the ineffective portion is recognized immediately in interest expense. Amounts reflected in AOCI related to the effective portion are reclassified into interest expense in the same period or periods during which the hedged transaction affects interest expense. 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 the 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 recognize the changes in the fair value in current-period earnings. The remaining balance in AOCI at the time we discontinue hedge accounting is not recognized in our Consolidated Income Statements unless it is probable that the forecasted cash flows will not occur. Such amounts are recognized in interest expense when the hedged transaction affects interest expense. When cash flow hedge accounting treatment is not applied, the changes in fair values related to interest rate-related derivatives between periods are recognized in interest expense in our Consolidated Income Statements. Net cash received or paid under derivative contracts is classified as operating cash flows in our Consolidated Statements of Cash Flows. Other tangible fixed assets Other tangible fixed assets consist primarily of leasehold improvements, computer equipment and office furniture, and are recorded at historical acquisition cost and depreciated at various rates over the asset’s estimated useful life on a straight-line basis. Depreciation expense on other tangible fixed assets is recorded in depreciation and amortization in our Consolidated Income Statements. Investments Equity securities without readily determinable fair values are carried at cost less impairment. We account for our investments with readily determinable fair values at fair value with all changes in fair value recognized in our Consolidated Income Statements. Income taxes Income tax expense is comprised of both current and deferred taxes. We recognize income tax expense in our Consolidated Income Statements, our Consolidated Statements of Comprehensive Income, and in our Consolidated Statements of Equity to the extent that it relates to items recognized directly in equity. We recognize the benefit of tax positions 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. We release tax effects from AOCI using a separate identification approach. We recognize interest and penalties related to underpayment of income taxes in income tax benefit (expense) in our Consolidated Income Statements and as a liability in accounts payable, accrued expenses and other liabilities in our Consolidated Balance Sheets. Deferred tax assets and liabilities We recognize deferred taxes resulting from temporary differences between the financial statement carrying amount and the tax basis 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 losses carried forward or deductible temporary differences are reduced by a valuation allowance to the amount that is more likely than not to be realized. Accrued maintenance liability We use the expense as incurred model for planned major maintenance. Under this method, the estimated maintenance costs are expensed in the period incurred. In many instances, there is a short-term timing difference between when we incur the expense and the actual payment of this liability to the third-party maintenance provider. When these timing differences occur, we recognize an expense and accrue the corresponding liability in the Accrued maintenance liability line item on our Consolidated Balance Sheets. When we lease a used aircraft, the maintenance condition of the aircraft generally will be less than 100% as a result of maintenance life usage by the prior lessee. For the next lessee of the used aircraft, we generally agree to reimburse the cost of the maintenance usage from the prior lessee, if and when the next lessee performs a qualifying maintenance event. These additional payments to our lessees related to prior lessee maintenance usage are generally referred to as “top-up” or lessor contribution payments which are considered to be a lessor cost and are expensed in the period incurred. These payments are in addition to our reimbursements of supplemental maintenance rents received from the current lessee during the lease period based on utilization. In cases of a lessor contribution, where an aircraft is subject to lease, we consider the maintenance event to be incurred when the maintenance event is completed by the lessee and we confirm that the maintenance event qualifies for reimbursement under the lease provisions. In cases where the aircraft is not subject to lease and we are directing the maintenance activity, we consider the maintenance to be incurred over the period the maintenance activity is performed. For all lease contracts acquired as part of the GECAS and ILFC transactions, 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 amounts are recorded as increases to interest expense in our Consolidated Income Statements. Debt and deferred debt issuance costs Long-term debt is carried at the principal amount borrowed, including unamortized discounts and premiums, fair value adjustments and debt issuance costs, where applicable. We amortize the amount of discounts, premiums 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. Debt issuance costs related to our line-of-credit arrangements are presented within other assets. 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 and our investments at fair value on a recurring basis and measure the fair value of flight equipment, goodwill and definite-lived intangible assets on a non-recurring basis. Refer to Note 31— Fair value measurements . Assets acquired and liabilities assumed as part of the GECAS Transaction were measured at their fair values on the acquisition date. Refer to Note 4— GECAS Transaction . Revenue recognition We lease flight equipment principally under operating leases and recognize basic lease rental income 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 uneven rental payments on a straight-line basis. The amount of the difference between basic lease rental revenue recognized and cash received is included in other assets, or in the event it is a liability, in accounts payable, accrued expenses and other liabilities. Lease agreements where rent is based on floating interest rates are included in minimum lease payments based on the floating interest rate that existed at the commencement of the lease. Increases or decreases in lease payments that result from subsequent changes in the floating interest rate are considered 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. We periodically evaluate the collectability of our operating lease contracts to determine the appropriate revenue recognition and measurement model to apply to each lessee. Accrual-based revenue recognition ceases on an operating lease contract when the collection of the rental payments is no longer probable and thereafter rental revenues are recognized using a cash receipts basis (“Cash Accounting”). In the period when collection of lease payments is no longer probable, any difference between revenue amounts recognized to date under the accrual method and payments that have been collected from the lessee, including security deposit amounts held, is recognized as a current period adjustment to lease revenue. Subsequently, revenues are recognized based on the lesser of the straight-line rental income or the lease payments collected from the lessee until such time that collection is probable. We apply significant judgment in assessing at each reporting date whether operating rental payments are probable of collection by reference to the credit status of each lessee, including lessees in bankruptcy-type arrangements, the extent of overdue balances and other relevant factors. Revenue from investment in finance leases is recognized using the interest method to produce a constant yield over the life of the lease and is included in basic lease rents for investment in finance leases and other income for loans. Most of our lease contracts require rental payments in advance. Rental payments received but unearned are recorded as deferred revenue in our Consolidated Balance Sheets. Under our flight equipment leases, the lessee is responsible for maintenance, repairs and other operating 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 lease revenue all supplemental maintenance rent receipts not expected to be reimbursed to the lessee. We estimate the total amount of maintenance reimbursements for the lease term and only record maintenance revenue after we have received sufficient maintenance rents to cover the total amount of estimated maintenance reimbursements during the remaining lease term. In most lease contracts not requiring the payment of supplemental maintenance rents, and to the extent that the aircraft is redelivered in a different condition than at acceptance, we generally receive EOL cash compensation for the difference at redelivery. Upon lease termination, we recognize receipt of EOL cash compensation as lease revenue to the extent those receipts exceed the EOL maintenance rights asset, and we recognize leasing expenses when the EOL maintenance rights asset exceeds the EOL cash received. The accrued maintenance liability existing at lease termination, if any, is recognized as lease revenue net of the MR contract maintenance rights asset. When flight equipment is sold, the portion of the accrued maintenance liability not specifically assigned to the buyer is released net of any maintenance rights asset balance and is included in net gain on sale of assets. Other income consists of proceeds from claims sales, interest revenue, management fee revenue, insurance proceeds and income related to other miscellaneous activities. We recognize revenue from bankruptcy claim sales when collectability of sales proceeds is reasonably assured and contingencies, if any, are resolved. Interest revenue from notes receivable and other interest-bearing instruments is recognized using the effective yield method as interest accrues under the associated contracts. Management fee revenue is recognized as income as it accrues 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 revenue recognition criteria are met. Net gain on sales of assets We sell flight equipment in the normal course of our operations to manage our fleet and to realize the residual value of the assets at the end of their economic lives. These sales may include aircraft, engines or helicopters on lease to airlines as well as assets that are not on lease. In some cases, the terms and conditions of asset sale transactions may include continuing equity or debt investments in the asset, post-sale performance guarantees of asset cash flows or servicing arrangements. The presence of any of these terms and conditions requires us to determine whether control of the underlying asset has been transferred to the buyer, and whether we no longer have significant ownership risk in the asset, both of which are required for a sale and resulting gain or loss to be recognized. Total loss write-offs Total loss write-offs result from the loss of an asset because of an unforeseen event (for example, an airplane crash incident, physical loss by wrongful deprivation, asset seizure, or other loss event). These events may be insured through the lessee’s insurance policies where we are named as the insured, and under our own insurance policies where the lessee’s insurance policy fails to indemnify us. We recognize an insurance receivable to the extent we have a claim from a loss from a total loss write-off event and the likelihood of recovering such loss or portion of the loss is probable at the balance sheet date. We recognize insurance proceeds in excess of the loss recognized when all contingencies are resolved, which generally occurs when we receive a non-refundable cash payment from the insurers, or when we execute a binding settlement agreement with the insurers where a non-refundable payment will be made. Unusual or infrequently occurring events or transactions A material event or transaction that we consider to be unusual in nature or that is expected to occur infrequently, or both, is reported separately in our Consolidated Income Statements, gross of income taxes. Allowance for credit losses We are exposed to credit losses on our investment in finance leases, net, and loans and notes receivable (collectively “Financing Receivables”). The credit exposure of our Financing Receivables reflects the risk that our customers fail to meet their payment obligations and the risk that the aircraft value in an investment in finance lease, net is less than the unguaranteed residual value. We estimate the expected risk of loss of our Financing Receivables over the remaining life using a probability of default and net exposure analysis. The probability of default is estimated based on historical cumulative default data, adjusted for current conditions of similarly risk-rated counterparties over the contractual term. The net exposure is estimated based on the exposure, net of the estimated aircraft value in the instance of investment in finance leases, net, and other cash collateral, including security deposits and maintenance-related deposits, over the contractual term. We also estimate the expected risk of loss on the unguaranteed residual value based on the estimated value of the aircraft at the expiry of the finance lease. Current expected credit loss provisions are classified as leasing expenses in our Consolidated Income Statements, with a corresponding allowance for credit loss amount reported as a reduction in the carrying amount of the related balance sheet amount. A write-off is recorded when all or part of the Financing Receivable is deemed uncollectable. Write-offs are charged against previously established allowances for credit losses. Partial or full recoveries of amounts previously written off are generally recognized as a reduction in the provision for credit losses. Refer to Note 26— Allowance for credit losses for further details. Share-based compensation Employees may receive AerCap share-based awards, consisting of restricted stock units or restricted stock. Share-based compensation expense is determined by reference to the fair value of the restricted stock units or restricted stock on the grant date and is recognized on a straight-line basis over the requisite service period. Share-based compensation expense is classified in selling, general and administrative expenses. Foreign currency Foreign currency transactions are translated into U.S. dollars at the exchange rate prevailing at the time of the transaction. Receivables or payables denominated in foreign currencies are remeasured into U.S. dollars at the exchange rate prevailing at the balance sheet date. All resulting exchange gains and losses are recorded in selling, general and administrative expenses in our Consolidated Income Statements. Foreign currency exchange gains or losses on our investments at fair value are recorded in gain (loss) on investments at fair value in our Consolidated Income Statements. 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 variable interest entity (“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 VIE’s 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. Earnings per share Basic Earnings (Loss) Per Share (“EPS”) is computed by dividing income available to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. For the purposes of calculating diluted EPS, the denominator includes both the weighted average number of ordinary shares outstanding during the period and the weighted average number of potentially dilutive ordinary shares, such as restricted stock units, restricted stock and stock options. In a period where a net loss is recognized, the denominator of the dilutive EPS calculation does not include potentially dilutive ordinary shares. 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 flight equipment. Accounting standards adopted during the year ended December 31, 2022 Reference Rate Reform In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASC 848”). ASC 848 provided temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to reduce the financial reporting burden in light of the market transition from London Interbank Offered Rates (“LIBOR”) and other reference interest rates to alternative reference rates. During the fourth quarter of 2022, we adopted ASC 848 (effective October 1, 2022). The adoption has not and is not expected to have a material impact on our financial statements. We have certain debt instruments, derivative contracts, and leases that reference LIBOR. LIBOR is a benchmark interest rate calculated based on information contributed by a panel of large international banks. LIBOR’s administrator announced in March 2021 that it intends to stop publishing the Overnight, 1-month, 3-month, 6-month and 12-month USD LIBOR settings after June 30, 2023. In anticipation of that cessation, we commenced the transition of our LIBOR based instrumen

GECAS Transaction

GECAS Transaction	12 Months Ended

Business Combination and Asset Acquisition [Abstract]
GECAS Transaction	GECAS Transaction AerCap completed the acquisition of 100% of GECAS, GE’s commercial aviation lessor and financier, on the Closing Date. Under the terms of the transaction agreement, GE received 111.5 million newly issued AerCap shares, $23 billion of cash and $1 billion of AerCap senior notes. Immediately following the completion of the GECAS Transaction, GE held approximately 46% of our issued and outstanding ordinary shares. AerCap is now the global leader across all areas of aviation leasing. The total consideration paid to GE had a value of $30.2 billion based on AerCap’s closing price per share of $59.04 on October 29, 2021. On the Closing Date, immediately after completing the GECAS Transaction, all GECAS assets were transferred substantially as an entirety to AerCap, and AerCap assumed substantially all of the liabilities of GECAS. In connection with the GECAS Transaction, on October 29, 2021, AerCap Global Aviation Trust (“AerCap Trust”) and AerCap Ireland Capital Designated Activity Company (“AICDC”) co-issued an aggregate principal amount of $21 billion of senior unsecured notes (the “GECAS Acquisition Notes”). The proceeds from the issuance of the GECAS Acquisition Notes were used to fund a portion of the cash consideration to be paid in the GECAS Transaction, and to pay related fees and expenses, with any excess proceeds to be used for general corporate purposes. On November 1, 2021, AerCap Trust and AICDC also co-issued an aggregate principal amount of $1 billion of 1.90% senior unsecured notes due 2025 to a subsidiary of GE in connection with the closing of the GECAS Transaction. Refer to Note 16— Debt . Immediately following the completion of the GECAS Transaction, GE held approximately 46% of our issued and outstanding ordinary shares. The GE shares were subject to a lock-up period which expired on February 1, 2023. GE has entered into agreements with AerCap regarding voting restrictions, standstill provisions and certain registration rights. The consideration transferred to effect the GECAS Transaction consisted of the following: Cash consideration $ 22,583,992 111,500,000 AerCap ordinary shares issued multiplied by AerCap closing share price per share of $59.04 on October 29, 2021 6,582,960 AerCap notes issued to GE 1,000,000 Consideration transferred $ 30,166,952 The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the Closing Date: Final Amounts Recognized as of the Closing Date Cash and cash equivalents $ 151,554 Restricted cash 4,850 Flight equipment held for operating leases, net 23,108,835 Investment in finance leases, net 1,165,382 Prepayments on flight equipment 2,990,414 Maintenance rights and lease premium, net (a) 3,984,212 Associated companies 555,212 Accrued maintenance liability (1,234,857) Deferred tax liabilities (1,195,168) Other assets and liabilities (b) 636,518 Estimate of fair value of net assets acquired $ 30,166,952 Consideration Transferred $ 30,166,952 Goodwill $ — (a) Included $2.8 billion maintenance rights asset and $1.2 billion lease premium asset, net. (b) The fair value of the assets acquired included current trade receivables of $245 million. The gross amount due under the contracts was $463 million. AerCap reported transaction and integration-related expenses related to the GECAS Transaction as provided in the table below.

The following unaudited pro forma summary presents consolidated information of AerCap as if the business combination had occurred on January 1, 2020: Year Ended December 31, 2021 2020 Total revenues and other income $ 7,866,898 $ 8,062,582 Net income 1,935,570 11,845 The most significant pro forma adjustments were to reflect the (net of tax) impact of: (i) the amortization of lease premium as an adjustment to revenue; (ii) the expensing of the maintenance rights asset, 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, 2020; (vi) other interest expense adjustments relating to the maintenance and security deposit liabilities; and (vii) nonrecurring transaction and integration-related expenses, as if they had been incurred as of January 1, 2020 instead of 2021. The above unaudited pro forma financial information is for informational purposes only and does not necessarily reflect the actual results of operations had the GECAS Transaction been completed on January 1, 2020. The pro forma information did not adjust for gain on sales and impairment charges. These pro forma amounts are not designed to represent the future expected financial results of AerCap. The GECAS Transaction resulted in significant increases of our asset and liabilities, as well as revenues and expenses.

Net charges related to Ukraine Conflict	Net charges related to Ukraine Conflict On February 24, 2022, Russia launched a large-scale military invasion of Ukraine and has since been engaged in a broad military conflict with Ukraine (the “Ukraine Conflict”). In response to the Ukraine Conflict and ongoing related hostilities, the United States, the European Union, the United Kingdom and other countries have imposed broad, far-reaching sanctions against Russia, certain Russian persons and certain activities involving Russia or Russian persons. These sanctions include prohibitions regarding the supply of aircraft and aircraft components to Russian persons or for use in Russia (the “Sanctions”). At the time of Russia’s launch of the Ukraine Conflict, we had 135 owned aircraft on lease to Russian airlines, as well as 14 owned engines on lease to Russian airlines, which represented approximately 5% of AerCap’s fleet by net book value as of December 31, 2021. Basic lease rents from our owned aircraft and engines leased to Russian airlines were approximately $33 million for the month of December 2021. We had no helicopters on lease to Russian customers. We have sought to repossess all of our aircraft and engines from Russian airlines and remove them from Russia. As of December 31, 2022, we had recovered 22 of our 135 owned aircraft and three of our 14 owned engines outside of Russia. While we continue to hold title to the aircraft that remain in Russia, we have concluded that it is not likely we will regain possession of these assets. In addition, at the time of Russia’s launch of the Ukraine Conflict, we had seven owned aircraft on lease to Ukrainian airlines. As of December 31, 2022, five of these aircraft were in temporary storage outside of Ukraine. As of December 31, 2022, the remaining two aircraft are grounded in Ukraine, but the exact status of these aircraft remains difficult to ascertain. In compliance with all applicable sanctions in March 2022, we terminated the leasing of all of our aircraft and engines with Russian airlines. These terminations have resulted in reduced revenues and operating cash flows. The Ukraine Conflict, the Sanctions and the actions of our former Russian lessees and the Russian government together represent an unusual and infrequent event and therefore the related net charges are classified separately on our Consolidated Income Statements. During 2022, we recognized a pre-tax net charge of $2.7 billion to our earnings, comprised of write-offs and impairments of flight equipment, which were partially offset by the derecognition of lease-related assets and liabilities (including maintenance rights and lease premium intangible assets, maintenance liabilities, security deposits and other balances) and the collection of letter of credit proceeds. We recognized a total loss write-off with respect to our assets that remain in Russia and Ukraine, and impairment losses with respect to the assets we have recovered from Russian and Ukrainian airlines. The impairments recognized with respect to assets recovered from Russian and Ukrainian airlines were based on the expected commercial strategy and corresponding cash flow estimates for each asset. Year ended December 31, 2022 (U.S. Dollars in millions) Write-offs and impairments of flight equipment (a) $ 3,160 Derecognition of lease-related assets and liabilities (237) Letters of credit receipts (257) Net charges related to Ukraine Conflict $ 2,666 (a) Includes $2.9 billion and $295 million of write-offs and impairments of flight equipment, respectively. We had letters of credit related to our aircraft and engines leased to Russian airlines as of February 24, 2022 of approximately $260 million, all confirmed by financial institutions in Western Europe. We presented requests for payment to all of these institutions. As of December 31, 2022, we had received payments of $257 million related to these letters of credit. Our lessees are required to provide insurance coverage with respect to leased aircraft and we are named as insureds under those policies in the event of a total loss of an aircraft or engine. We also purchase contingent and possessed insurance (“C&P Policy”) which provides us with coverage when our flight equipment is not subject to a lease or where a lessee’s policy fails to indemnify us. In March 2022, we submitted an insurance claim for approximately $3.5 billion under our C&P Policy with respect to all aircraft and engines remaining in Russia. In June 2022, we commenced legal proceedings in London, England to recover up to $3.5 billion in connection with our previously submitted claim under the C&P Policy. Refer to Note 30— Commitments and Contingencies for further details.

Discontinued Operations and Disposal Groups [Abstract]
Flight equipment held for sale	Flight equipment held for sale Generally, flight equipment is classified as held for sale when the sale is probable, the asset is available for sale in its present condition, and it is expected to be sold within one year. Flight equipment assets are reclassified from flight equipment held for operating leases to flight equipment held for sale at the lower of the asset carrying value or fair value, less costs to sell. Depreciation is no longer recognized for flight equipment classified as held for sale. As of December 31, 2022, flight equipment with a total net book value of $292.8 million was classified as flight equipment held for sale in our Consolidated Balance Sheet. Aggregate maintenance and security deposit amounts received from lessees of approximately $67 million will be assumed by the buyers of these assets upon consummation of the individual sale transactions.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative financial instruments	Derivative financial instruments We have entered into interest rate derivatives to hedge the current and future interest rate payments on our variable rate debt. These derivative financial instruments can include interest rate swaps, caps, floors, options and forward contracts. As of December 31, 2022, we had interest rate caps and swaps outstanding, with underlying variable benchmark interest rates ranging from one six During 2022, we transitioned a number of our longer-dated derivative instruments from LIBOR to Term SOFR. We applied an optional expedient under ASC 848 that allowed us to account for the contract modifications as a continuation of the existing contract without further analysis, and to continue cash flow hedging relationships without dedesignation. Some of our agreements with derivative counterparties require a two-way cash collateralization of derivative fair values. As of December 31, 2022 and 2021, we had cash collateral of $4.6 million and $0.3 million, respectively, from various counterparties and the obligation to return this collateral was recorded in accounts payable, accrued expenses and other liabilities. We had not advanced any cash collateral to counterparties as of December 31, 2022 or 2021. The counterparties to our interest rate derivatives are primarily major international financial institutions. We continually monitor our positions and the credit ratings of the counterparties involved and limit the amount of credit exposure to any one party. We could be exposed to potential losses due to the credit risk of non-performance by these counterparties. We have not experienced any losses to date. Our derivative assets are recorded in other assets and our derivative liabilities are recorded in accounts payable, accrued expenses and other liabilities in our Consolidated Balance Sheets.

Maturities of our debt financings (excluding fair value adjustments, debt issuance costs, debt discounts and debt premium) as of December 31, 2022 were as follows: Maturities of debt financing (a) 2023 $ 6,162,330 2024 8,343,844 2025 5,832,335 2026 7,542,036 2027 2,669,525 Thereafter 16,250,047 $ 46,800,117 (a) For further detail on debt maturities, please refer to “Item 5. Operating and Financial Review and Prospects—Contractual obligations.” During the years ended December 31, 2022, 2021 and 2020, we amortized as interest expense debt issuance costs, debt discounts and debt premium of $82.4 million, $65.8 million and $57.2 million, respectively. AerCap Trust & AICDC Notes From time to time, AerCap Trust and AICDC have co-issued additional senior unsecured notes (the “AGAT/AICDC Notes”). The following table provides a summary of the outstanding AGAT/AICDC Notes as of December 31, 2022: Maturities of AGAT/AICDC Notes 2023 $ 4,100,000 2024 6,800,000 2025 3,650,000 2026 5,250,000 2027 1,600,000 Thereafter 11,300,000 $ 32,700,000 All of the AGAT/AICDC Notes bear interest at fixed rates ranging from 0.68% to 6.50%. The AGAT/AICDC Notes are jointly and severally and fully and unconditionally guaranteed by AerCap Holdings N.V. and by AerCap Ireland Limited (“AerCap Ireland”), AerCap Aviation Solutions B.V., ILFC and AerCap U.S. Global Aviation LLC. Except as described below, the AGAT/AICDC Notes are not subject to redemption prior to their stated maturity and there are no sinking fund requirements. We may redeem each series of the AGAT/AICDC 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. 16. Debt (Continued) The indentures governing the AGAT/AICDC Notes contain customary covenants that, among other things, restrict our, and our restricted subsidiaries’, ability to incur liens on assets and to 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 AGAT/AICDC Notes, the failure to comply with covenants and agreements specified in the indentures, 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. On May 25, 2022, AerCap Trust and AICDC completed the redemption of all $500 million outstanding aggregate principal amount of the 4.625% Senior Notes due 2022. GECAS Acquisition Notes AerCap Trust and AICDC co-issued an aggregate principal amount of $21 billion of senior unsecured notes (the “GECAS Acquisition Notes”) in connection with the GECAS Transaction on October 29, 2021. The GECAS Acquisition Notes consist of $1.75 billion aggregate principal amount of 1.15% Senior Notes due 2023, $3.25 billion aggregate principal amount of 1.65% Senior Notes due 2024, $1.0 billion aggregate principal amount of 1.75% Senior Notes due 2024, $3.75 billion aggregate principal amount of 2.45% Senior Notes due 2026, $3.75 billion aggregate principal amount of 3.0% Senior Notes due 2028, $4.0 billion aggregate principal amount of 3.3% Senior Notes due 2032, $1.5 billion aggregate principal amount of 3.4% Senior Notes due 2033, $1.5 billion aggregate principal amount of 3.85% Senior Notes due 2041 and $500 million aggregate principal amount of Floating Rate Senior Notes due 2023. The GECAS Acquisition Notes are fully and unconditionally guaranteed on a senior unsecured basis by AerCap and certain other AerCap subsidiaries. The proceeds from the issuance of the GECAS Acquisition Notes were used to fund a portion of the cash consideration paid in the GECAS Transaction, and to pay related fees and expenses, with any excess proceeds used for general corporate purposes. On November 1, 2021, AerCap Trust and AICDC also co-issued an aggregate principal amount of $1 billion of 1.90% senior unsecured notes due 2025 to a subsidiary of GE in connection with the closing of the GECAS Transaction. Revolving credit facilities In March 2018, AerCap entered into a $950 million unsecured revolving and term loan agreement (the “Asia Revolver”) with a maturity of March 2022. In August 2021, AerCap amended and extended the Asia Revolver, reducing its size to $684 million and extending its maturity to February 2024. In March 2014, AICDC entered into a senior unsecured revolving credit facility (the “Citi Revolver I”). In October 2019, AICDC amended the Citi Revolver I, increased the size to $4 billion (with an option for AerCap to increase the size by an additional $0.5 billion) and extended the maturity to February 2024. In February 2023, AICDC amended and extended the Citi Revolver I, extending its maturity to February 2027. On March 30, 2021, AerCap and AICDC entered into a $4.35 billion unsecured revolving credit agreement (the “Citi Revolver II”) with a syndicate of lenders and Citibank N.A., as administrative agent, and a maturity of September 30, 2025. On March 30, 2021, the Citi Revolver I was amended such that the terms of both the Citi Revolver I and the Citi Revolver II are the same (the “Citi Revolvers”). In February 2023, the terms of the Citi Revolvers were amended to replace LIBOR with Term SOFR as the relevant reference rate. The obligations under the revolving credit facilities are guaranteed by AerCap Holdings N.V. and certain of its subsidiaries. Availability of borrowings under the revolving credit facilities is subject to the satisfaction of customary conditions precedent. We have the right to terminate or cancel, in whole or in part, the unused portions of the commitment amounts. Availability of borrowings under the Citi Revolver II commenced upon the Closing Date. The Revolving credit facilities contain covenants customary for unsecured financings of this type, including financial covenants that require us to maintain compliance with a maximum ratio of consolidated indebtedness to shareholders’ equity, a minimum fixed charge coverage ratio and a maximum ratio of unencumbered assets to certain financial indebtedness. The facilities also contain covenants that, among other things, restrict, subject to certain exceptions, the ability of AerCap to sell assets, make certain restricted payments and incur certain liens. 16. Debt (Continued) Export credit facilities The principal amounts under the export credit facilities amortize over ten The obligations under the export credit facilities are guaranteed by AerCap Holdings N.V. and/or certain of its subsidiaries, as well as various export credit agencies. Institutional secured term loans and secured portfolio loans The following table provides details regarding the terms of our outstanding institutional secured term loans and secured portfolio loans: As of December 31, 2022 2021 Collateral (Number of aircraft) (a) Amount outstanding Weighted average Maturity Amount outstanding Institutional secured term loans Setanta 78 $ 2,000,000 6.73 % 2028 $ 2,000,000 Hyperion 71 1,050,000 6.48 % 2023 1,050,000 Secured portfolio loans Celtago & Celtago II 24 731,480 4.14 % 2027 869,550 Cesium 15 658,580 5.27 % 2025 726,398 Goldfish 13 560,084 6.13 % 2025 616,649 Scandium 10 517,577 5.31 % 2025 573,770 Rhodium 11 459,599 4.27 % 2026 506,202 Other secured facilities 42 1,522,019 3.85 % 2024-2032 2,085,965 264 $ 7,499,339 $ 8,428,534 (a) These loans are secured by a combination of aircraft and the equity interests in the borrower and certain special purpose entity (“SPE”) subsidiaries of the borrower that own the aircraft. Institutional secured term loans The Hyperion institutional term loan was originally entered into in 2014. The obligations of the borrowers of the loan are guaranteed by AerCap Holdings N.V. and certain of its subsidiaries. A $2 billion institutional secured term loan (“Setanta”) was entered into on November 5, 2021. The obligations of the borrowers of the loan are guaranteed by AerCap Holdings N.V. and AerCap Ireland. Both the Hyperion loan and the Setanta loan contain customary covenants and events of default for financings of this type, including covenants that limit the ability of the subsidiary borrowers and their subsidiaries to incur additional indebtedness and create liens, and covenants that limit the ability of the guarantors, the subsidiary borrowers and their subsidiaries to consolidate, merge or dispose of all or substantially all of their assets and enter into transactions with affiliates. 16. Debt (Continued) Secured portfolio loans The obligations of each of the respective borrowers under each secured portfolio loan are guaranteed by AerCap Holdings N.V. and certain of its subsidiaries. These loans contain customary covenants and events of default for financings of this type, including covenants that limit the ability of the borrower and its subsidiaries to incur additional indebtedness and create liens, and covenants that limit the ability of the guarantors and the borrower and its subsidiaries to consolidate, merge or dispose of all or substantially all of their assets or enter into transactions with affiliates. During the fourth quarter of 2022, the terms of the Celtago and Cesium facilities were amended to replace LIBOR with Term SOFR as the relevant reference rate. The margin on these facilities remains unchanged, and the maturity on the Celtago facility has been extended to December 2027. The terms of the Scandium, Rhodium and Celtago II facilities were also amended to replace LIBOR with Term SOFR as the relevant reference rate. These amendments will become effective during the first quarter of 2023. We applied an optional expedient under ASC 848 that allowed us to account for the contract modifications as a continuation of the existing contract without further analysis. AerFunding Revolving Credit Facility AerFunding 1 Limited (“AerFunding”) is an SPE whose share capital is owned 95% by a charitable trust and 5% by AerCap Ireland. AerFunding is a consolidated subsidiary formed for the purpose of acquiring aircraft assets. In April 2006, AerFunding entered into a non-recourse senior secured revolving credit facility. In December 2020, this facility was amended to extend its revolving period to June 2022, following which there is a 32-month term out period. Borrowings under the AerFunding Revolving Credit Facility are secured by, among other things, security interests in and pledges or assignments of equity ownership and beneficial interests in all of the subsidiaries of AerFunding, as well as by AerFunding’s interests in the leases of its assets. In March 2022, AerFunding amended this facility, extending the revolving period to September 2024, following which there is a 30-month term-out period. The final maturity date of the AerFunding Revolving Credit Facility is March 2027. Other secured debt AerCap has entered into a number of financings, provided by a range of banks and non-bank financial institutions, to fund the purchase of aircraft and for general corporate purposes. The majority of the financings are guaranteed by AerCap and are secured by, among other things, a pledge of the shares of the subsidiaries owning the related aircraft and, in certain cases, a mortgage on the applicable aircraft. All of our financings contain affirmative covenants customary for secured financings of this type. Subordinated debt The following table provides a summary of the outstanding subordinated debt as of December 31, 2022: As of December 31, 2022 2021 Amount Weighted average interest rate Maturity Amount ECAPS Subordinated Notes (a) $ 1,000,000 6.39 % 2065 $ 1,000,000 2045 Subordinated Notes 500,000 6.50 % 2045 500,000 2079 Subordinated Notes 750,000 5.88 % 2079 750,000 $ 2,250,000 $ 2,250,000 (a) Enhanced Capital Advantaged Preferred Securities (“ECAPS”). 16. Debt (Continued) ECAPS Subordinated Notes In December 2005, ILFC issued two tranches of subordinated notes in an aggregate principal amount of $1 billion. Both the $400 million and $600 million tranches have a floating interest rate, with margins of 1.80% and 1.55% respectively, plus the highest of three-month LIBOR, ten-year constant maturity U.S. Treasury, and 30-year constant maturity U.S. Treasury. Upon consummation of the ILFC Transaction, the subordinated notes were assumed by AerCap Trust, and AerCap Holdings N.V. and certain of its subsidiaries became guarantors. ILFC remains a co-obligor under the indentures governing the subordinated notes. The addition of these subsidiary guarantors did not affect the subordinated ranking of these notes. The ECAPS contain customary financial tests, including a minimum ratio of equity to total managed assets and a minimum fixed charge coverage ratio. 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’s or ILFC’s capital stock 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. 2045 Junior Subordinated Notes In June 2015, AerCap Trust issued $500 million of junior subordinated notes due 2045 (the “2045 Junior Subordinated Notes”). The 2045 Junior Subordinated Notes currently bear interest at a fixed interest rate of 6.5% and, beginning in June 2025, will bear interest at the three-month benchmark rate plus 4.3%. The 2045 Junior Subordinated Notes are guaranteed by AerCap Holdings N.V. and certain of its subsidiaries. We may defer any interest payments on the 2045 Junior Subordinated Notes for up to five consecutive deferral periods. At the end of five years following the commencement of any deferral period, we must pay all accrued and unpaid deferred interest, including compounded interest. We may at our option redeem the 2045 Junior Subordinated Notes before their maturity in whole or in part, at any time and from time to time, on or after June 15, 2025 at 100% of their principal amount plus any accrued and unpaid interest thereon. The 2045 Junior Subordinated Notes are junior subordinated unsecured obligations, rank equally with all of the issuer’s and the guarantors’ future equally ranking junior subordinated indebtedness, if any, and are subordinate and junior in right of payment to all of the issuer’s and the guarantors’ existing and future unsubordinated indebtedness. 16. Debt (Continued) 2079 Junior Subordinated Notes In October 2019, AerCap Holdings N.V. issued $750 million of junior subordinated notes due 2079 (the “2079 Junior Subordinated Notes”). The 2079 Junior Subordinated Notes currently bear interest at a fixed interest rate of 5.875% and, from October 2024, will bear interest at a rate equal to the five-year U.S. Treasury Rate plus 4.535%, to be reset on each subsequent five-year anniversary. We may forgo payment of interest on the 2079 Junior Subordinated Notes for any interest period. Upon a forgoing of interest, we will have no obligation to pay the forgone interest on the payment date or at any future date. The 2079 Junior Subordinated Notes are guaranteed by certain of AerCap Holdings N.V.’s subsidiaries. We may at our option redeem the 2079 Junior Subordinated Notes before their maturity in whole or in part on October 10, 2024 (the “First Call Date”) and on each subsequent five-year anniversary of the First Call Date, at 100% of their principal amount plus any accrued and unpaid interest thereon for the then-current six-month interest period. The 2079 Junior Subordinated Notes are junior subordinated unsecured obligations, rank equally with all of the issuer’s and the guarantors’ future equally ranking junior subordinated obligations, if any, and are subordinate and junior in right of payment to all of the issuer’s and the guarantors’ present and future creditors (i) who are unsubordinated creditors, (ii) who are subordinated only to the claims of unsubordinated creditors, or (iii) who are subordinated creditors except those whose claims rank equally with or junior to the 2079 Junior Subordinated Notes. As of December 31, 2022, the 2079 Junior Subordinated Notes rank senior only to the issuer’s and the guarantors’ common and preferred stock. Subordinated debt issued by VIEs

Income Tax Disclosure [Abstract]
Income taxes	Income taxes Our subsidiaries are subject to income taxation in a number of tax jurisdictions, principally Ireland and the United States. Loss before income taxes and income of investments accounted for under the equity method for 2022 includes a loss of $1.1 billion relating to Ireland. Income before income taxes and income of investments accounted for under the equity method for 2021 includes $1.1 billion relating to Ireland.

(c) The 2022 permanent differences included other permanent differences of $3.7 million. (d) The 2021 permanent differences included non-deductible expenses of $152.8 million, non-taxable income of $151.2 million and other permanent differences of $116.9 million.

The calculation of income for income tax purposes differs significantly from financial statement income. Deferred tax is provided to reflect the impact of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and such amounts as measured under tax law in the various jurisdictions. Operating loss carryforwards and accelerated tax depreciation on flight equipment held for operating leases give rise to our most significant temporary differences. The following tables provide details regarding the principal components of our deferred tax liabilities and assets by significant jurisdiction as of December 31, 2022 and 2021: As of December 31, 2022 Ireland United States Other Total Flight equipment $ (3,315,574) $ (47,505) $ (4,290) $ (3,367,369) Intangibles (295,480) 17,268 1 (278,211) Accrued maintenance liability (11,451) 1,179 1,432 (8,840) Associated companies — (3,973) — (3,973) Deferred losses on sale of assets — 13,509 — 13,509 Valuation allowance (16,285) (87,509) (16,167) (119,961) Operating loss and tax credit carryforwards 1,828,473 140,970 33,449 2,002,892 Other (222,308) 109 388 (221,811) Net deferred tax (liabilities) assets $ (2,032,625) $ 34,048 $ 14,813 $ (1,983,764) As of December 31, 2021 Ireland United States Other Total Flight equipment $ (3,091,396) $ 214,404 $ (7,103) $ (2,884,095) Intangibles (390,846) (7,092) — (397,938) Accrued maintenance liability (20,286) 292 — (19,994) Obligations under capital leases and debt obligations (2,079) (178,299) — (180,378) Associated companies — (10,507) — (10,507) Deferred losses on sale of assets — 17,079 — 17,079 Valuation allowance (10,664) (112,177) (29,236) (152,077) Operating loss and tax credit carryforwards 1,726,510 87,199 27,314 1,841,023 Other (185,787) 9,863 (848) (176,772) Net deferred tax (liabilities) assets $ (1,974,548) $ 20,762 $ (9,873) $ (1,963,659) The net deferred tax liabilities as of December 31, 2022 of $2.0 billion were recognized in our Consolidated Balance Sheet as deferred tax assets of $210.3 million (consisting of deferred tax assets of $330.2 million less valuation allowances of $120.0 million) and as deferred tax liabilities of $2.2 billion. The net deferred tax liabilities as of December 31, 2021 of $2.0 billion were recognized in our Consolidated Balance Sheet as deferred tax assets of $121.6 million (consisting of deferred tax assets of $273.7 million less valuation allowances of $152.1 million) and as deferred tax liabilities of $2.1 billion. The following table presents the movements in the valuation allowance for deferred tax assets during the years ended December 31, 2022 and 2021: Year Ended December 31, 2022 2021 Valuation allowance at beginning of period $ 152,077 $ 79,393 GECAS Transaction — 61,263 (Decrease) Increase of allowance included in income tax expense (32,116) 11,421 Valuation allowance at end of period $ 119,961 $ 152,077 The Company has assessed, on a jurisdictional basis, the realization of its deferred tax assets, including the ability to carry back net operating losses, the existence of taxable temporary differences, the availability of tax planning strategies and available sources of future taxable income. The Company has concluded that based on cumulative taxable income and future taxable income that it will be able to realize a benefit for its deferred tax assets in certain jurisdictions. In addition, the Company has concluded that a valuation allowance on its deferred tax assets in Ireland, the U.S. and certain other jurisdictions continues to be appropriate considering income projections and uncertainty with respect to future taxable income. During the year ended December 31, 2022, the Company released a net valuation allowance of $32.1 million as an income tax benefit, made up of gross decreases of $37.9 million and gross increases of $5.8 million. The Company determined that the positive evidence outweighed the negative evidence, resulting in the valuation allowance release. It is possible that within the next 12 months there may be sufficient positive evidence to release a portion of the remaining valuation allowance. Release of a portion of the remaining valuation allowance would result in a benefit to income tax expense for the period the release is recorded, which could have an impact on net earnings. The timing and amount of the potential valuation allowance release are subject to significant management judgment, as well as prospective earnings in Ireland, the United States and certain other foreign entities and jurisdictions As of December 31, 2022 and 2021, we had $31.8 million and $37.5 million, respectively, of unrecognized tax benefits. Substantially all of the unrecognized tax benefits as of December 31, 2022, 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. Our major tax jurisdictions are Ireland and the United States. Our tax returns are open for examination in Ireland from 2018 forward and in the United States from 2018 forward. Global Tax Reform On October 8, 2021, 136 countries, including Ireland, approved a statement, known as the OECD BEPS Inclusive Framework (“IF”), providing a framework for BEPS 2.0, which builds upon the Blueprints. The IF and revised Pillar Two Blueprint include a global minimum effective tax rate of 15% for groups with a global turnover in excess of €750 million, subject to certain exclusions. The OECD published detailed rules to assist in the implementation of the Pillar 2 rules involving 137 countries on December 20, 2021, and again on March 14, 2022. These detailed rules should allow some countries to introduce the Pillar 2 rules into domestic legislation during the course of 2023. On December 22, 2021, the European Commission published a proposed EU Directive to incorporate the Pillar 2 tax rules into EU law, and has also issued further publications since that date. On December 12, 2022, the EU council unanimously agreed to adopt this Directive giving EU countries until December 31, 2023 to transpose the Directive into domestic legislation. Further guidance is expected from the OECD and the EU as to how certain aspects of the Pillar Two Blueprint and the Directive will operate mechanically, and as such it is difficult to determine the degree to which these changes may result in an increase in our effective tax rate and cash tax liabilities in future periods. Overall, these developments make it more likely that this initiative will have an adverse impact on our effective tax rate and cash tax liabilities in future periods. Ireland Since 2006, the enacted Irish corporate income tax rate has been 12.5%. Some of our Irish tax-resident operating subsidiaries have significant operating loss carryforwards as of December 31, 2022, which give rise to deferred tax assets. The availability of these operating loss carryforwards of $14.6 billion does not expire with time. In addition, the vast majority of all of our Irish tax-resident subsidiaries are entitled to accelerated aircraft depreciation for income tax purposes and to shelter net taxable income with the surrender of losses on a current year basis within the Irish tax group. Based on projected taxable profits in our Irish subsidiaries, we expect to recover the majority of the value of our Irish deferred tax assets and have not recognized a valuation allowance against such assets, with the exception of $16.3 million, as of December 31, 2022. There are also $11.7 million of tax credit carryforwards available in Ireland. A valuation allowance has been recognized in full against these tax credit carryforwards. United States Our U.S. subsidiaries are assessable to federal and state income taxes. We have one significant group of U.S. companies that file a consolidated return. The blended federal and state statutory income tax rate applicable to our combined U.S. group was 21.5% for the year ended December 31, 2022. Our U.S. federal net operating loss carryforwards generated in tax years beginning before December 31, 2017 of $230.7 million expire between 2028 and 2038. The U.S. federal net operating loss carryforwards generated in tax years beginning after December 31, 2017 of $154.2 million have an unlimited carryforward period.

Share-Based Payment Arrangement, Noncash Expense [Abstract]
Share-based compensation	Share-based compensation Under our equity incentive plans, we grant restricted stock units and restricted stock to directors, officers and employees to attract and retain them on competitive terms, and to incentivize superior performance with a view to creating long-term value for the benefit of the Company, its shareholders and other stakeholders. AerCap equity grants In March 2012, we implemented an equity incentive plan (the “Equity Incentive Plan 2012”) which provides for the grant of equity awards to participants of the plan selected by the Nomination and Compensation Committee of our Board of Directors. The maximum number of equity awards available under the plan is equivalent to 8,064,081 ordinary shares. The Equity Incentive Plan 2012 is not open for equity awards to our directors. On May 14, 2014, we implemented an equity incentive plan (the “Equity Incentive Plan 2014”) which provides for the grant of equity awards to participants of the plan selected by the Nomination and Compensation Committee of our Board of Directors. The maximum number of equity awards initially available under the plan was equivalent to 4,500,000 ordinary shares. The 2021 AGM increased the number of equity awards available under the plan to 8,500,000 ordinary shares. The Equity Incentive Plan 2014 is open for equity awards to our directors. The Equity Incentive Plan 2014 and Equity Incentive Plan 2012 are collectively referred to herein as “AerCap Equity Plans.” The terms and conditions, including the vesting conditions, of the equity awards granted under AerCap Equity Plans are determined by the Nomination and Compensation Committee and, for our directors, by the Board of Directors in line with the remuneration policies approved by the General Meeting of Shareholders. The vesting periods of the majority of equity awards range between three In 2021, we granted certain restricted stock units the terms of which provided that those units would only vest if the average closing price of AerCap’s ordinary shares on the New York Stock Exchange is at least $75 or $90 for any 30 calendar day period to April 30, 2026 (the “Market Condition RSUs”). As discussed below, the Ukraine Conflict, the Sanctions and the actions of our former Russian lessees and the Russian government together represent an unusual and infrequent event that required us to recognize a pre-tax net charge of $2.7 billion to our earnings. Refer to Note 5— Net charges related to Ukraine Conflict to our Consolidated Financial Statements included in this annual report for further details. After considering the impact of the foregoing, our Board of Directors determined that, if we are unable to successfully collect on our claims under the C&P policy or the Russian airlines’ policies, the share price targets for the Market Condition RSUs would no longer effectively serve their purpose of retaining and properly incentivizing our key employees. Our Board of Directors therefore determined that, to ensure that the Market Condition RSUs served as an effective retention and incentive tool, the share price targets for the Market Condition RSUs should be adjusted to reflect the impact on the Company of the net charges related to Ukraine Conflict. The adjustments also provide that the revised share price targets will be appropriately raised if we collect on any of our claims under the C&P Policy or the Russian airlines’ policies, with the targets potentially resetting to or exceeding their original levels. The following table presents movements in the outstanding restricted stock units and restricted stock under the AerCap Equity Plans during the year ended December 31, 2022: Year Ended December 31, 2022 Number of service-based restricted stock units and restricted stock Number of performance-based restricted stock units and restricted stock Weighted average grant date fair value of service-based grants ($) Weighted average grant date fair value of performance-based grants ($) Number at beginning of period 3,140,879 5,009,792 $ 47.80 $ 51.15 Granted (a) 505,843 295,311 50.00 51.68 Vested (b) (689,780) (1,269,994) 40.77 51.31 Forfeited (27,357) (24,118) 46.23 46.91 Number at end of period 2,929,585 4,010,991 $ 49.94 $ 51.18 (a) Includes 390,659 shares of restricted stock granted under the AerCap Equity Plans, of which 282,532 shares of restricted stock were issued, with the remaining 108,127 ordinary shares being withheld and applied to pay the taxes involved. As part of the 108,127 ordinary shares withheld to pay for taxes, 56,041 ordinary shares were treated as granted and subsequently vested on the grant date under specific Irish tax legislation. As a result, we recognized an expense of $2.6 million on the grant dates associated with these ordinary shares. (b) 424,608 restricted stock units, which were previously granted under the AerCap Equity Plans, vested. In connection with the vesting of the restricted stock units, the Company issued, in full satisfaction of its obligations, 262,106 ordinary shares to the holders of these restricted stock units, with the remainder being withheld and applied to pay the taxes in respect of those awards. Restrictions on 1,479,126 shares of restricted stock (1,242,598 shares of restricted stock net of withholding for taxes) lapsed during the period. In addition, 56,041 ordinary shares were treated as granted and subsequently vested on the grant dates, as described in (a) above. In general, the amount of share-based compensation expense is determined by reference to the fair value of the restricted stock units or restricted stock on the grant date, based on the trading price of the Company’s shares on the grant date and reflective of the probability of vesting. The share-based compensation expense was $102.8 million and $96.1 million, and the related income tax benefit was $13.1 million and $10.5 million for the years ended December 31, 2022 and 2021, respectively. The following table presents our expected share-based compensation expense based on existing grants, assuming that the established performance criteria are met and that no forfeitures occur: Expected share-based compensation expense (U.S. Dollars in millions) 2023 $ 82.0 2024 67.8 2025 33.1 2026 5.9

During the year ended December 31, 2021, we increased our credit provision, classified in leasing expenses by $83.7 million primarily due to a customer settlement, the increase in finance leases, notes receivable and loan balances due to the GECAS Transaction and to reflect the ongoing credit risk due to the Covid-19 pandemic. Substantially all our Financing Receivables portfolio is secured lending and we assess the overall quality of the portfolio based on Financing Receivables by airline customer risk rating as defined below. Our internal risk ratings process is an important source of information in determining our allowance for credit losses and represents a comprehensive approach to evaluating risk in our Financing Receivables portfolio. We stratify our Financing Receivables portfolio into three categories: A, B and C. An internal risk rating is developed for our airline customers, which is based upon our proprietary model using data derived from the airline customer financial statements and other relevant data points that may impact our airline customer’s ability to honor its financial commitments. The frequency of rating updates is established by our credit risk policy, which requires periodic monitoring and at least an annual review. The latest credit rating review was performed as of December 31, 2022. 26.

Earnings Per Share [Abstract]
Earnings per share	Earnings per share Basic EPS is calculated by dividing net (loss) income by the weighted average number of our ordinary shares outstanding, which excludes 4,837,602, 5,822,811 and 2,552,346 shares of unvested restricted stock as of December 31, 2022, 2021 and 2020, respectively. In general, for the calculation of diluted EPS, the weighted average of our ordinary shares outstanding for basic EPS is adjusted by the effect of dilutive securities provided under our equity compensation plans. Due to the reported loss for the year ended December 31, 2022, basic EPS was not adjusted by the effect of dilutive securities. The number of ordinary shares under our equity compensation plans which could dilute EPS in the future was 3,099,221 for the year ended December 31, 2022. The number of shares excluded from diluted shares outstanding was 122,237 for the year ended December 31, 2021, because the effect of including those shares in the calculation would have been anti-dilutive. Due to the reported loss for the year ended December 31, 2020, basic EPS was not adjusted by the effect of dilutive securities. The number of ordinary shares under our equity compensation plans which could dilute EPS in the future was 2,630,066 for the year ended December 31, 2020. The computations of basic and diluted EPS for the years ended December 31, 2022, 2021 and 2020 were as follows: Year Ended December 31, 2022 2021 2020 Net (loss) income for the computation of basic EPS $ (726,041) $ 1,000,507 $ (298,566) Weighted average ordinary shares outstanding—basic 240,486,849 146,421,188 127,743,828 Basic EPS $ (3.02) $ 6.83 $ (2.34) Year Ended December 31, 2022 2021 2020 Net (loss) income for the computation of diluted EPS $ (726,041) $ 1,000,507 $ (298,566) Weighted average ordinary shares outstanding—diluted 240,486,849 149,005,981 127,743,828 Diluted EPS $ (3.02) $ 6.71 $ (2.34) The computations of ordinary shares outstanding, excluding shares of unvested restricted stock, as of December 31, 2022, 2021 and 2020 were as follows: As of December 31, 2022 2021 2020 Number of ordinary shares Ordinary shares issued 250,347,345 250,347,345 138,847,345 Treasury shares (4,416,070) (4,951,897) (8,448,807) Ordinary shares outstanding 245,931,275 245,395,448 130,398,538 Shares of unvested restricted stock (4,837,602) (5,822,811) (2,552,346) Ordinary shares outstanding, excluding shares of unvested restricted stock 241,093,673 239,572,637 127,846,192

Variable Interest Entities [Abstract]
Variable interest entities	Variable interest entities We use many forms of entities to achieve our leasing and financing 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 of the VIE’s activities, or being the sole shareholder of the VIE. During the year ended December 31, 2022, we did not provide any financial support to any of our VIEs that we were not contractually obligated to provide. Consolidated VIEs As of December 31, 2022 and 2021, substantially all assets and liabilities presented in our Consolidated Balance Sheets were held in consolidated VIEs. We have determined that we are the PB of these entities because we control and manage all aspects of these entities, including directing the activities that most significantly affect the entities’ economic performance, absorb the majority of the risks and rewards of these entities and guarantee the activities of these entities. The assets of our consolidated VIEs that can only be used to settle obligations of these entities, and the liabilities of these VIEs for which creditors do not have recourse to our general credit, are disclosed in our Consolidated Balance Sheets under Supplemental balance sheet information. Further details of debt held by our consolidated VIEs are disclosed in Note 16— Debt . Wholly-owned ECA and Ex-Im financing vehicles We have created certain wholly-owned subsidiaries for the purpose of purchasing flight equipment and obtaining financing secured by such flight equipment. The secured debt is guaranteed by the European ECAs and the Export-Import Bank of the United States. These 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. Other secured financings We have created a number of wholly-owned subsidiaries for the purpose of obtaining secured financings. These 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. Wholly-owned leasing entities We have created wholly-owned subsidiaries for the purpose of facilitating aircraft leases with airlines. These 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, which serve as equity. Limited recourse financing structures We have established entities to obtain secured financings for the purchase of aircraft in which we have variable interests. These 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. The loans of these entities are non-recourse to us except under limited circumstances. As of December 31, 2022, these entities had aggregate subordinated debt outstanding of $54.4 million, consisting of $27.2 million due to us and $27.2 million due to our joint venture partner. AerFunding We hold a 5% equity investment and 100% of the subordinated notes (“AerFunding Class E-1 Notes”) in AerFunding.

Related Party Transactions [Abstract]
Related party transactions	Related party transactions GE As described in Note 4— GECAS Transaction , AerCap completed the acquisition of 100% of GECAS, GE’s commercial aviation lessor and financier, on November 1, 2021. Under the terms of the transaction agreement, GE received 111.5 million newly issued AerCap shares, $23 billion of cash and $1 billion of AerCap senior notes. Immediately following the completion of the GECAS Transaction, GE held approximately 46% of our issued and outstanding ordinary shares. Consequently, GE became a related party upon the Closing Date of the GECAS Transaction. We may purchase, sell or lease flight equipment from/to GE and GE provides services to AerCap under a transition services agreement. During the year ended December 31, 2022, AerCap recognized rental income from engines on lease to GE of approximately $143 million and purchases from and provision of services from GE of approximately $150 million. During the year ended December 31, 2022, AerCap recognized sales to GE of approximately $27 million.

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Commitments and contingencies Flight equipment on order As of December 31, 2022, we had commitments to purchase 435 new aircraft for delivery through 2027, excluding aircraft for which we have cancellation rights that we expect to exercise. These commitments are primarily based upon purchase agreements with Boeing, Airbus and Embraer S.A. (“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, 2022, we also had commitments to purchase 47 new engines and 18 new helicopters for delivery through 2025. As of December 31, 2022, we had made non-refundable deposits on these purchase commitments (exclusive of capitalized interest and fair value adjustments) of approximately $3.5 billion. A portion of the aggregate purchase price for the acquisition of flight equipment will be funded by incurring additional debt. The amount of the indebtedness to be incurred will depend on the final purchase price of the asset, which can vary due to a number of factors, including inflation. Prepayments on flight equipment include prepayments of our forward order flight equipment and other balances held by the flight equipment manufacturers. Movements in prepayments on flight equipment during the years ended December 31, 2022 and 2021 were as follows: Year Ended December 31, 2022 2021 Prepayments on flight equipment at beginning of period $ 4,586,848 $ 2,111,659 GECAS Transaction — 2,990,414 Prepayments and additions during the period, net 244,937 136,655 Interest paid and capitalized during the period 104,191 30,827 Prepayments and capitalized interest applied to the purchase of flight equipment (1,129,374) (682,707) Prepayments on flight equipment at end of period $ 3,806,602 $ 4,586,848 During the year ended December 31, 2022, we incurred $104 million of interest expense which was fully capitalized. The following table presents our contractual commitments for the purchase of flight equipment as of December 31, 2022: 2023 2024 2025 2026 2027 Thereafter Total (U.S. Dollars in millions) Purchase obligations (a) $ 6,821.9 $ 7,302.3 $ 5,725.0 $ 3,367.9 $ 835.0 $ — $ 24,052.1 (a) As of December 31, 2022, we had commitments to purchase 435 aircraft (including 17 purchase and leaseback transactions and excluding aircraft for which we have cancellation rights that we expect to exercise), 47 engines, 18 helicopters and other commitments through 2027. The timing of our purchase obligations is based on current estimates and incorporates expected delivery delays into the table above. In addition, we have the right to reschedule the delivery dates of certain of our aircraft to future dates. Legal proceedings General 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 indemnities and insurance coverage, where applicable. Based on information currently available, we believe the potential outcome of those cases where we are able to estimate reasonably possible losses, and our estimate of the reasonably possible losses exceeding amounts already recognized, on an aggregated basis, is immaterial to our Consolidated Financial Statements. Contingent and Possessed Insurance Policy Litigation During the year ended December 31, 2022, we submitted an insurance claim for approximately $3.5 billion under our contingent and possessed insurance policy (the “C&P Policy”) with respect to 135 aircraft and 14 engines which had been on lease to Russian airlines at the time of the invasion of Ukraine, the vast majority of which remain in Russia. On June 9, 2022, AerCap Ireland Limited (as representative claimant on its own behalf and on behalf of all other insureds under the C&P Policy) commenced a claim in the Commercial Court in London, England (i) in the amount of approximately $3.5 billion against AIG Europe S.A. (on its own behalf and on behalf of all underwriters subscribing to the Aircraft Hull and Spares and Equipment Coverage section of the C&P Policy) and (ii) in the alternative, in the amount of $1.2 billion against Lloyds Insurance Company S.A. (on its own behalf and on behalf of all underwriters subscribing to the Aviation “War and Allied Perils” Coverage section of the C&P Policy), in respect of AerCap’s aircraft and engines lost in Russia. Fidelis Insurance Ireland DAC was joined as a defendant to the action on January 13, 2023 and is no longer represented by AIG Europe S.A. or Lloyds Insurance Company S.A for its respective interests under the C&P Policy. We intend to continue to vigorously pursue our claims under the C&P Policy. However, the collection, timing and amount of any potential recoveries are uncertain and we have not recognized any claim receivables as of December 31, 2022. VASP litigation We are party to a group of related cases arising from the leasing of 13 aircraft and three spare engines to Viação Aerea de São Paulo (“VASP”), a Brazilian airline. In 1992, VASP defaulted on its lease obligations and we commenced litigation against VASP to repossess our equipment and obtained a preliminary injunction for the repossession and export of 13 aircraft and three spare engines from VASP. We repossessed and exported the aircraft and engines. VASP appealed and in 1996, the Appellate Court of the State of São Paulo (“TJSP”) ruled that the aircraft and engines should be returned or that VASP could recover proven damages arising from the repossession. We have defended this case in the Brazilian courts through various motions and appeals. In 2004, the Superior Court of Justice (the “STJ”) dismissed our then-pending appeal. In 2005, we filed an extraordinary appeal with the Federal Supreme Court (the “STF”). On June 24, 2020, the STF reversed its earlier contrary rulings and granted our extraordinary appeal, ordering a new panel of the STJ to review the merits of our challenge against TJSP’s original order. VASP’s final appeal has been denied and we expect the case to return to the STJ for a ruling on the merits of our original appeal. In 2006, VASP commenced a related proceeding to calculate the amount of alleged damages owed under the TJSP’s 1996 judgment. In 2017, the court decided that VASP had suffered no damages even if the TJSP’s 1996 judgment regarding liability were affirmed. On April 20, 2018, VASP appealed this decision. We believe, however, and we have been advised, that it is not probable that VASP will ultimately be able to recover damages from us even if VASP prevails on the issue of liability. The outcome of the legal process is, however, uncertain. The ultimate amount of damages, if any, payable to VASP cannot reasonably be estimated at this time. We continue to actively pursue all courses of action that may reasonably be available to us and intend to defend our position vigorously. In 2006, we brought actions against VASP in English and Irish courts seeking damages arising from the 1992 lease defaults. These actions resulted in judgments by the English court in the aggregate amount of approximately $40 million plus interest and judgments by the Irish court in the aggregate amount of approximately $36.9 million, all in our favor. VASP had meanwhile in 2008 been adjudicated as insolvent by a Brazilian bankruptcy court, which commenced bankruptcy proceedings. We have caused the English and Irish judgment to be domesticated in Brazil and submitted them as claims in the bankruptcy proceeding. The bankruptcy court has allowed the claims in the amount of $40 million in respect of the English judgments and $24 million in respect of the Irish judgments. We have been advised that it is not probable that VASP’s bankruptcy estate will have funds to pay its creditors but our court-approved claims may be used to offset any damages that VASP might be awarded in the Brazilian courts if for any reason we are not successful in defending ourselves against VASP’s claim for damages. Transbrasil litigation We are party to a group of related actions arising from the leasing of various aircraft and engines to Transbrasil S/A Linhas Areas (“Transbrasil”), a now-defunct Brazilian airline. By 1998, Transbrasil had defaulted on various obligations under its leases with AerCap-related companies (the “AerCap Lessors”), along with other leases it had entered into with General Electric Capital Corporation (“GECC”) and certain of its affiliates (collectively with GECC, the “GE Lessors”). GECAS was the servicer for all these leases at the time. Subsequently, Transbrasil issued promissory notes (the “Notes”) to the AerCap Lessors and GE Lessors (collectively, the “Lessors”) in connection with restructurings of the leases. Transbrasil defaulted on the Notes and the Lessors individually, brought enforcement actions against Transbrasil in 2001 (GECC also filed an action for the involuntary bankruptcy of Transbrasil). Transbrasil brought a lawsuit against the Lessors in February 2001 (the “Transbrasil Lawsuit”), claiming that the Notes had in fact been paid at the time the Lessors brought the enforcement actions. In 2007, the trial judge ruled in favor of Transbrasil and the Lessors appealed. In April 2010, the appellate court published a judgment (the “2010 Judgment”) rejecting the Lessors’ appeal, ordering them to pay Transbrasil statutory penalties equal to double the face amount of the Notes (plus interest and monetary adjustments) as well as damages for any losses incurred as a result of the attempts to collect on the Notes. The 2010 Judgment provided that the amount of such losses would be calculated in separate proceedings in the trial court (the “Indemnity Claim”). In June 2010, the Lessors filed special appeals before the STJ in Brazil. In October 2013, the STJ granted the special appeals filed by the GE Lessors, effectively reversing the 2010 Judgment in most respects as to all of the Lessors. Transbrasil appealed this order, but the appellate panel in November 2016 rejected Transbrasil’s appeal, preserving the 2013 reversal of the 2010 Judgment. All appeals in respect of the Transbrasil Lawsuit based on the merits of the dispute have now concluded. However, in July 2011, while the various appeals of the 2010 Judgment were pending, Transbrasil brought three actions for provisional enforcement of the 2010 Judgment (the “Provisional Enforcement Actions”): one to enforce the award of statutory penalties; a second to recover attorneys’ fees related to that award, and a third to enforce the Indemnity Claim. Transbrasil submitted its alleged calculation of statutory penalties, which, according to Transbrasil, amounted to approximately $210 million in the aggregate against all defendants, including interest and monetary adjustments. In light of the STJ’s ruling in October 2013, the trial court has ordered the dismissal of the Transbrasil Provisional Enforcement Actions. The TJSP has since affirmed the dismissals of the actions seeking statutory penalties and attorneys’ fees. Lessors’ motion to clarify relating to the dismissal of the Provisional Enforcement Action with respect to the Indemnity Claim remains pending. We believe we have strong arguments to convince the court that Transbrasil suffered no material damage as a result of the defendants’ attempts to collect on the Notes. The only matters remaining to be resolved are: (i) a motion to clarify relating to the dismissal of a lower court appeal with respect to the Indemnity Claim and (ii) a number of court-mandated legal fee assessments for (a) proofs of claim filed by the Lessors against the Transbrasil bankruptcy estate and (b) various otherwise-concluded enforcement proceedings, including the Provisional Enforcement Proceedings.

Fair value measurements

Fair Value Disclosures [Abstract]
Fair value measurements	Fair value measurements The Company determines fair value based on the 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. It is our policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements, in accordance with the fair value hierarchy as described below. Where limited or no observable market data exists, fair value measurements for assets and liabilities are primarily based on management’s own estimates and are calculated based upon the economic and competitive environment, the characteristics of the asset or liability and other such factors. Therefore, the results may not be realized in actual sale or immediate settlement of the asset or liability. The degree of judgment used in measuring the fair value of a financial and non-financial asset or liability generally correlates with the level of pricing observability. We classify our fair value measurements based on the observability and significance of the inputs used in making the measurement, as provided below: Level 1—Quoted prices available in active markets for identical assets or liabilities as of the reported date. Level 2—Observable market data. Inputs include quoted prices for similar assets, liabilities (risk adjusted) and market-corroborated inputs, such as market comparables, interest rates, yield curves and other items that allow value to be determined. Level 3—Unobservable inputs from our own assumptions about market risk developed based on the best information available, subject to cost benefit analysis. Inputs may include our own data. Fair value measurements are classified in their entirety based on the lowest level of input that is significant to their fair value measurement. Assets and liabilities measured at fair value on a recurring basis As of December 31, 2022 and 2021, our derivative portfolio consisted of interest rate swaps and caps. The fair value of derivatives is based on dealer quotes for identical instruments. We have also considered the credit rating and risk of the counterparty of the derivative contract based on quantitative and qualitative factors. As such, the valuation of these instruments was classified as Level 2. As of December 31, 2022 and 2021, we held investments at fair value of $59.1 million and $38.4 million, respectively. The valuation of these investments were primarily classified as Level 1, based on quoted market price. During the year ended December 31, 2022, we recognized losses on investments at fair value of $17.7 million. During the years ended December 31, 2021, and 2020 we recognized a gain on investment at fair value of $2.3 million and a loss on investment of $143.5 million, respectively. The following tables present our financial assets and liabilities that we measured at fair value on a recurring basis by level within the fair value hierarchy as of December 31, 2022 and 2021: December 31, 2022 Total Level 1 Level 2 Level 3 Assets Investments, at fair value $ 59,081 $ 39,081 $ — $ 20,000 Derivative assets 211,993 — 211,993 — December 31, 2021 Total Level 1 Level 2 Level 3 Assets Investment, at fair value $ 38,367 $ 38,367 $ — $ — Derivative assets 16,909 — 16,909 — Liabilities Derivative liabilities $ 71,197 $ — $ 71,197 $ — Assets and liabilities measured at fair value on a non-recurring basis We measure the fair value of certain definite-lived intangible assets and our flight equipment on a non-recurring basis, when U.S. GAAP requires the application of fair value, including when events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable. Management develops the assumptions used in the fair value measurements. Therefore, the fair value measurements of definite-lived intangible assets and flight equipment are classified as Level 3 valuations. Flight equipment Inputs to non-recurring fair value measurements categorized as Level 3 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. Key inputs to the income statement approach include the discount rate, current contractual lease cash flows, projected future non-contractual lease or sale cash flows, extended to the end of the aircraft’s estimated holding period in its highest and best use, and a contractual or estimated disposition value. 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 the airframe and engine configuration of the aircraft. The projected non-contractual lease cash flows are applied to follow-on lease terms, which are estimated based on the age of the aircraft at the time of re-lease and are assumed through the estimated holding period of the aircraft. The estimated holding period is the period over which future cash flows are assumed to be generated. Shorter holding periods can result when a potential sale or future disassembly of an aircraft for the sale of its parts (“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 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 disposition value assumed is based on an estimated part-out value or the contracted sale price. The estimated future cash flows, as described above, are then discounted to present value. The discount rate used is based on the aircraft type and incorporates assumptions market participants would use regarding the likely debt and equity financing components, and the required returns of those financing components. For flight equipment that we measured at fair value on a non-recurring basis, as a result of aircraft that were impaired, during the year ended December 31, 2022, the following table presents the fair value of such flight equipment that were impaired as of the measurement date, the valuation technique and the related unobservable inputs: Fair value Valuation technique Unobservable input Weighted average Flight equipment $ 459,883,544 Income approach Discount rate 7 % Non-contractual cash flows as a % of total cash flows 93 % The significant unobservable inputs utilized in the fair value measurement of flight equipment are the discount rate and the non-contractual cash flows. The discount rate is affected by movements in the aircraft funding markets, including fluctuations in required rates of return in debt and equity, and loan to value ratios. The non-contractual cash flows represent management’s estimate of the non-contractual cash flows over the remaining life of the aircraft. An increase in the discount rate would decrease the fair value measurement of the aircraft, while an increase in the estimated non-contractual cash flows would increase the fair value measurement of the aircraft. Fair value disclosures of financial instruments The fair value of restricted cash and cash and cash equivalents approximates their carrying value because of their short-term nature (Level 1). The fair value of our long-term unsecured debt is estimated using quoted market prices for similar or identical instruments, depending on the frequency and volume of activity in the market. The fair value of our long-term secured debt is estimated using a discounted cash flow analysis based on current market interest rates and spreads for debt with similar characteristics (Level 2). Derivatives are recognized in our Consolidated Balance Sheets at their fair value. The fair value of derivatives is based on dealer quotes for identical instruments. We have also considered the credit rating and risk of the counterparties of the derivative contracts based on quantitative and qualitative factors (Level 2). As of December 31, 2022 and 2021, we held investments at fair value of $59.1 million and $38.4 million, respectively. The valuation of these investments were primarily classified as Level 1, based on quoted market price. As of December 31, 2022 and 2021 loans receivable and notes receivable carried at amortized cost had estimated fair values of $329.7 million and $486.2 million, and $403.4 million and $616.9 million respectively, and were classified as Level 3. All of our financial instruments are carried at amortized cost, other than our derivatives and investments which are measured at fair value on a recurring basis. The carrying amounts and fair values of our most significant financial instruments as of December 31, 2022 and 2021 were as follows: December 31, 2022 Carrying value Fair value Level 1 Level 2 Level 3 Assets Cash and cash equivalents $ 1,597,147 $ 1,597,147 $ 1,597,147 $ — $ — Restricted cash 159,623 159,623 159,623 — — Loans receivable 351,357 329,650 — — 329,650 Notes receivable 486,223 486,223 — — 486,223 Investments, at fair value 59,081 59,081 39,081 — 20,000 Derivative assets 211,993 211,993 — 211,993 — $ 2,865,424 $ 2,843,717 $ 1,795,851 $ 211,993 $ 835,873 Liabilities Debt $ 46,801,683 (a) $ 42,525,932 $ — $ 42,525,932 $ — $ 46,801,683 $ 42,525,932 $ — $ 42,525,932 $ — (a) Excludes debt issuance costs, debt discounts and debt premium.

Subsequent Events [Abstract]
Subsequent events	Subsequent events Share repurchase program In March 2023, our Board of Directors approved a share repurchase program authorizing total repurchases of up to $500 million of AerCap ordinary shares through September 30, 2023. Repurchases under the program may be made through open market purchases or privately negotiated transactions in accordance with applicable U.S. federal securities laws. The timing of repurchases and the exact number of common shares to be purchased will be determined by the Company's management, in its discretion, and will depend upon market conditions and other factors. The program will be funded using the Company's cash on hand and cash generated from operations. The program may be suspended or discontinued at any time. Revolving credit facility amendment and extension In March 2014, AICDC entered into a senior unsecured revolving credit facility (the “Citi Revolver I”) which was subsequently upsized and amended. In February 2023, AICDC extended the Citi Revolver I, extending its maturity to February 2027. Insurance claims relating to aircraft remaining in Ukraine In January 2023, we submitted insurance claims for $100 million under our C&P Policy for our two aircraft which remain in Ukraine. We intend to continue to vigorously pursue such claims under the C&P Policy. However, the collection, timing and amount of any potential recoveries are uncertain.

Accounting Policies [Abstract]
General	General Our Consolidated Financial Statements are presented in accordance with Accounting Principles Generally Accepted in the United States of America (“U.S. GAAP”). We consolidate all companies in which we have effective control and all variable interest entities (“VIEs”) for which we are deemed the Primary Beneficiary (“PB”) under Accounting Standards Codification (“ASC”) 810. All intercompany balances and transactions with consolidated subsidiaries are eliminated. The results of consolidated entities are included from the effective date of control or, in the case of VIEs, from the date that we are or become the PB. The results of subsidiaries sold or otherwise deconsolidated are excluded from the date that we cease to control the subsidiary or, in the case of VIEs, when we cease to be the PB. Our Consolidated Financial Statements are stated in U.S. dollars, which is our functional currency.
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.
Risk and Uncertainties	Risk and Uncertainties In the normal course of business, we encounter several significant types of economic risk, including credit risk, market risk and risks associated with exposure to the aviation industry. Credit risk is the risk of a lessee’s inability or unwillingness to make contractually required payments and to fulfill its other contractual obligations. Market risk reflects the change in the value of financings due to changes in interest rate spreads or other market factors, including the value of collateral underlying financings. Risks associated with exposure to the aviation industry include the risk of a downturn in the commercial aviation industry, which could adversely impact lessee ability to make payments, increase the risk of unscheduled lease terminations and depress lease rates and the value of the Company’s flight equipment. The Covid-19 pandemic continues to pose a range of risks to our business. The emergence of new variants, developments in the public health situation, the reimposition or continuation of travel restrictions, and other pandemic-related complications could have a negative impact on our business. We face significant competition and our business may be adversely affected if market participants change as a result of restructuring or bankruptcies, mergers and acquisitions, or new entities entering or exiting the industry. After a sustained period of relatively low inflation rates, current rates of inflation are above or near recent historical highs in the United States, the European Union, the United Kingdom, and other countries. High rates of inflation may have a number of adverse effects on our business. Inflation may increase the costs of goods, services and labor used in our operations, thereby increasing our expenses. Increased global inflation has contributed to rising interest rates, which may affect our lease revenues, our interest expense, the market value of our interest rate derivatives, and the market value of our flight equipment. We are exposed to geopolitical, economic and legal risks associated with the international operations of our business and those of our lessees, including many of the economic and political risks associated with emerging markets. We are exposed to concentrated political and economic risks in certain geographical regions in which our lessees are concentrated. The Russian invasion of Ukraine and the impact of resulting sanctions by the United States, the European Union, the United Kingdom and other countries has adversely affected and may continue to affect our business and financial condition, results and cash flows.

Flight equipment is depreciated to its estimated residual value on a straight-line basis over the useful life of the asset. The costs of improvements to flight equipment are normally recorded as leasing expenses unless the improvement increases the long-term value of the flight equipment. In that case, the capitalized improvement cost is depreciated over the estimated remaining useful life of the asset.

(b) Estimated industry price, except where more relevant information indicates that a different residual value is more appropriate. We periodically review the estimated useful lives and residual values of our flight equipment based on our industry knowledge, external factors, such as current market conditions, and changes in our disposition strategies, to determine if they are appropriate, and record adjustments to depreciation rates prospectively on an individual asset basis, as necessary. We test flight equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. The quarterly impairment assessments are primarily triggered by potential sale transactions, leasing transactions, early terminated leases, credit events impacting lessees or forecasted significant and permanent declines in the demand for asset types. The quantitative impairment test is performed at the lowest level for which identifiable cash flows are largely independent of other groups of assets, which is the individual asset, including the lease-related assets and liabilities of that asset, such as the maintenance rights assets, lease incentives, and maintenance liabilities (the “Asset Group”). If the sum of the expected undiscounted future cash flows is less than the Asset Group, an impairment loss is recognized. The loss is measured as the excess of the carrying value of the Asset Group over its estimated fair value. Fair value reflects the present value of future cash flows expected to be generated from the assets, including its expected residual value, discounted at a rate commensurate with the associated risk. Future cash flows are assumed to occur under 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 assets and industry trends. On an annual basis, we also perform an assessment of all assets older than five years and held for operating leases to identify potential impairment by reference to estimated future cash flows at the Asset Group level, and perform a quantitative impairment test. We apply significant judgment in assessing whether an impairment is necessary and in estimating significant input assumptions including the future lease rates, maintenance cash flow forecasts, the residual value and the discount rate when performing quantitative impairment tests. During the lease term, our leases require that the lessee maintain our flight equipment and either provide periodic maintenance rental payments during the lease or provide EOL compensation payments based on the maintenance usage of the flight equipment. In addition, upon lease expiry, the flight equipment undergoes inspection to verify compliance with lease return conditions. We believe that the requirement that the lessee compensate us for the maintenance usage of the flight equipment and our emphasis on maintenance and inspection helps preserve residual values and generally helps us to recover our investment in our leased flight equipment.
Capitalization of interest	Capitalization of interest We capitalize interest on prepayments of forward order flight equipment and add such amounts to prepayments on flight equipment. The amount of interest capitalized is the amount of interest costs which could have been avoided in the absence of such prepayments.
Investment in finance and sales-type leases, net	Investment in finance, sales-type and leveraged leases, net (“Investment in finance leases, net”)Finance leases include direct financing leases, sales-type leases and leveraged leases. If a lease meets specific criteria under U.S. GAAP, we recognize the lease in investment in finance leases, net in our Consolidated Balance Sheets and de-recognize the asset from flight equipment held for operating lease. For sales-type leases, we recognize the difference between the asset carrying value and the amount recognized in investment in finance leases, net in net gain on sale of assets in our Consolidated Income Statements. The amounts recognized for finance and sales-type leases consist of lease receivables and the estimated unguaranteed residual value of the flight equipment on the lease termination date, less the unearned income and net of the allowance for credit losses. Expected unguaranteed residual values are based on our assessment of the values of the flight equipment and, if applicable, the estimated EOL payments expected at the expiration of the lease. The unearned income is recognized as lease revenue over the lease term, using the interest method to produce a constant yield over the life of the lease. Finance leases that are mainly financed at commencement with non-recourse borrowings and that meet certain criteria are accounted for as leveraged leases. Leveraged leases are recorded at the aggregate of rentals receivable, net of that portion of the rental applicable to principal and interest on the non-recourse debt, plus the estimated residual value of the leased asset less unearned income. Unearned income is recognized as lease interest income at a level rate of return on the leveraged lease net investment.
Definite-lived intangible assets	Definite-lived intangible assets We recognize intangible assets acquired in a business combination at fair value on the date of acquisition. Amortization of definite-lived intangible assets is either event-driven or is at a rate based on the period over which we expect to derive economic benefits from such assets. Maintenance rights and lease premium, net Maintenance rights assets are recognized when we acquire flight equipment subject to existing leases. These assets represent the contractual right to receive the aircraft in a specified maintenance condition at the end of the lease under lease contracts with EOL payment provisions, or our right to receive the aircraft in better maintenance condition due to aircraft maintenance events performed by the lessee either through reimbursement of maintenance deposit rents held under lease contracts with maintenance reserve provisions, or through a lessor contribution to the lessee. For leases with EOL maintenance provisions, upon lease termination, we recognize receipt of EOL cash compensation as lease revenue to the extent those receipts exceed the EOL maintenance rights asset, and we recognize leasing expenses when the EOL maintenance rights asset exceeds the EOL cash received. For leases with maintenance reserve payment provisions, we recognize maintenance rights expense at the time the lessee submits a reimbursement claim and provides the required documentation related to the cost of a qualifying maintenance event that relates to pre-acquisition usage. Lease premium assets represent the value of an acquired lease where the contractual rental payments are above the market rate. We amortize the lease premium assets on a straight-line basis over the term of the lease as a reduction of lease revenue. Other definite-lived intangible assets, net Other definite-lived intangible assets primarily consist of customer relationships recorded at fair value when we acquired International Lease Finance Corporation (“ILFC”). Intangible assets are amortized over the period during which we expect to derive economic benefits from such assets. The amortization expense is recorded in depreciation and amortization. We evaluate definite-lived intangible assets for impairment when events or changes in circumstances indicate that the carrying value of the asset may not be recoverable.
Associated companies	Associated companies Unconsolidated investments where we do not have a controlling financial interest, but over which we have significant influence, are accounted for using the equity method of accounting. Under the equity method of accounting, we recognize our share of earnings and losses based on our ownership percentage of such investments in equity in net earnings (losses) of investments accounted for under the equity method in our Consolidated Income Statements. The carrying amount of the equity method investment is included in Associated companies on our Consolidated Balance Sheets. Refer to Note 11— Associated companies for further details. Distributions received from equity method investees are classified using the cumulative earnings approach. Under this approach, distributions received are considered returns on investment and are classified as cash inflows from operating activities, unless the cumulative distributions received, less distributions received in prior periods that were determined to be returns of investment, exceed cumulative equity in earnings recognized. When such an excess occurs, the current-period distribution up to this excess is deemed to be a return of investment, and is classified as cash inflows from investing activities.
Other assets	Other assets Other assets consist of debt issuance costs, lease incentives, loans receivable, notes receivable, operating lease right-of-use (“ROU”) assets, derivative assets, other tangible fixed assets, straight-line rents, prepaid expenses, inventory, investments and other receivables.
Lease incentives	Lease incentives 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 receivables	Notes receivableNotes receivable primarily arise from the restructuring and deferral of trade receivables from lessees experiencing financial difficulties.
Loans	Loans Loans are classified as held for investment (“HFI”) when the Company has the intent and ability to hold the loan for the foreseeable future or until maturity. Loans classified as HFI are recorded at amortized cost. Loan origination fees and certain direct origination costs are deferred and recognized as adjustments to interest income over the contractual lives of the related loans. If we no longer have the intent and ability to hold a loan for the foreseeable future, then the loan is transferred to assets held for sale (“HFS”) at the lower of carrying value or estimated fair value less costs to sell. Once classified as HFS, the amount by which the carrying value exceeds fair value is recognized in our Consolidated Income Statements as an impairment loss. In a purchase and leaseback transaction where the seller/lessee effectively retains control of the flight equipment asset, the purchase and leaseback is accounted for as a loan financing.
Derivative financial instruments	Derivative financial instruments We use derivative financial instruments to manage our exposure to interest rate risks. Derivatives are carried in our Consolidated Balance Sheets at fair value. When cash flow hedge accounting treatment is applied, the changes in fair values related to the effective portion of the derivatives are recorded in accumulated other comprehensive income (loss) (“AOCI”), and the ineffective portion is recognized immediately in interest expense. Amounts reflected in AOCI related to the effective portion are reclassified into interest expense in the same period or periods during which the hedged transaction affects interest expense. 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 the 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 recognize the changes in the fair value in current-period earnings. The remaining balance in AOCI at the time we discontinue hedge accounting is not recognized in our Consolidated Income Statements unless it is probable that the forecasted cash flows will not occur. Such amounts are recognized in interest expense when the hedged transaction affects interest expense. When cash flow hedge accounting treatment is not applied, the changes in fair values related to interest rate-related derivatives between periods are recognized in interest expense in our Consolidated Income Statements.
Other tangible fixed assets	Other tangible fixed assets Other tangible fixed assets consist primarily of leasehold improvements, computer equipment and office furniture, and are recorded at historical acquisition cost and depreciated at various rates over the asset’s estimated useful life on a straight-line basis. Depreciation expense on other tangible fixed assets is recorded in depreciation and amortization in our Consolidated Income Statements.
Investments	InvestmentsEquity securities without readily determinable fair values are carried at cost less impairment. We account for our investments with readily determinable fair values at fair value with all changes in fair value recognized in our Consolidated Income Statements.
Income taxes	Income taxesIncome tax expense is comprised of both current and deferred taxes. We recognize income tax expense in our Consolidated Income Statements, our Consolidated Statements of Comprehensive Income, and in our Consolidated Statements of Equity to the extent that it relates to items recognized directly in equity. We recognize the benefit of tax positions 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. We release tax effects from AOCI using a separate identification approach. We recognize interest and penalties related to underpayment of income taxes in income tax benefit (expense) in our Consolidated Income Statements and as a liability in accounts payable, accrued expenses and other liabilities in our Consolidated Balance Sheets.
Deferred tax assets and liabilities	Deferred tax assets and liabilities We recognize deferred taxes resulting from temporary differences between the financial statement carrying amount and the tax basis 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 losses carried forward or deductible temporary differences are reduced by a valuation allowance to the amount that is more likely than not to be realized.
Accrued maintenance liability	Accrued maintenance liability We use the expense as incurred model for planned major maintenance. Under this method, the estimated maintenance costs are expensed in the period incurred. In many instances, there is a short-term timing difference between when we incur the expense and the actual payment of this liability to the third-party maintenance provider. When these timing differences occur, we recognize an expense and accrue the corresponding liability in the Accrued maintenance liability line item on our Consolidated Balance Sheets. When we lease a used aircraft, the maintenance condition of the aircraft generally will be less than 100% as a result of maintenance life usage by the prior lessee. For the next lessee of the used aircraft, we generally agree to reimburse the cost of the maintenance usage from the prior lessee, if and when the next lessee performs a qualifying maintenance event. These additional payments to our lessees related to prior lessee maintenance usage are generally referred to as “top-up” or lessor contribution payments which are considered to be a lessor cost and are expensed in the period incurred. These payments are in addition to our reimbursements of supplemental maintenance rents received from the current lessee during the lease period based on utilization. In cases of a lessor contribution, where an aircraft is subject to lease, we consider the maintenance event to be incurred when the maintenance event is completed by the lessee and we confirm that the maintenance event qualifies for reimbursement under the lease provisions. In cases where the aircraft is not subject to lease and we are directing the maintenance activity, we consider the maintenance to be incurred over the period the maintenance activity is performed.
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, fair value adjustments and debt issuance costs, where applicable. We amortize the amount of discounts, premiums 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. Debt issuance costs related to our line-of-credit arrangements are presented within other assets.
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 and our investments at fair value on a recurring basis and measure the fair value of flight equipment, goodwill and definite-lived intangible assets on a non-recurring basis. Refer to Note 31— Fair value measurements
Revenue recognition	Revenue recognition We lease flight equipment principally under operating leases and recognize basic lease rental income 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 uneven rental payments on a straight-line basis. The amount of the difference between basic lease rental revenue recognized and cash received is included in other assets, or in the event it is a liability, in accounts payable, accrued expenses and other liabilities. Lease agreements where rent is based on floating interest rates are included in minimum lease payments based on the floating interest rate that existed at the commencement of the lease. Increases or decreases in lease payments that result from subsequent changes in the floating interest rate are considered 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. We periodically evaluate the collectability of our operating lease contracts to determine the appropriate revenue recognition and measurement model to apply to each lessee. Accrual-based revenue recognition ceases on an operating lease contract when the collection of the rental payments is no longer probable and thereafter rental revenues are recognized using a cash receipts basis (“Cash Accounting”). In the period when collection of lease payments is no longer probable, any difference between revenue amounts recognized to date under the accrual method and payments that have been collected from the lessee, including security deposit amounts held, is recognized as a current period adjustment to lease revenue. Subsequently, revenues are recognized based on the lesser of the straight-line rental income or the lease payments collected from the lessee until such time that collection is probable. We apply significant judgment in assessing at each reporting date whether operating rental payments are probable of collection by reference to the credit status of each lessee, including lessees in bankruptcy-type arrangements, the extent of overdue balances and other relevant factors. Revenue from investment in finance leases is recognized using the interest method to produce a constant yield over the life of the lease and is included in basic lease rents for investment in finance leases and other income for loans. Most of our lease contracts require rental payments in advance. Rental payments received but unearned are recorded as deferred revenue in our Consolidated Balance Sheets. Under our flight equipment leases, the lessee is responsible for maintenance, repairs and other operating 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 lease revenue all supplemental maintenance rent receipts not expected to be reimbursed to the lessee. We estimate the total amount of maintenance reimbursements for the lease term and only record maintenance revenue after we have received sufficient maintenance rents to cover the total amount of estimated maintenance reimbursements during the remaining lease term. In most lease contracts not requiring the payment of supplemental maintenance rents, and to the extent that the aircraft is redelivered in a different condition than at acceptance, we generally receive EOL cash compensation for the difference at redelivery. Upon lease termination, we recognize receipt of EOL cash compensation as lease revenue to the extent those receipts exceed the EOL maintenance rights asset, and we recognize leasing expenses when the EOL maintenance rights asset exceeds the EOL cash received. The accrued maintenance liability existing at lease termination, if any, is recognized as lease revenue net of the MR contract maintenance rights asset. When flight equipment is sold, the portion of the accrued maintenance liability not specifically assigned to the buyer is released net of any maintenance rights asset balance and is included in net gain on sale of assets. Other income consists of proceeds from claims sales, interest revenue, management fee revenue, insurance proceeds and income related to other miscellaneous activities. We recognize revenue from bankruptcy claim sales when collectability of sales proceeds is reasonably assured and contingencies, if any, are resolved. Interest revenue from notes receivable and other interest-bearing instruments is recognized using the effective yield method as interest accrues under the associated contracts. Management fee revenue is recognized as income as it accrues 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 revenue recognition criteria are met.
Net gain on sales of assets	Net gain on sales of assetsWe sell flight equipment in the normal course of our operations to manage our fleet and to realize the residual value of the assets at the end of their economic lives. These sales may include aircraft, engines or helicopters on lease to airlines as well as assets that are not on lease. In some cases, the terms and conditions of asset sale transactions may include continuing equity or debt investments in the asset, post-sale performance guarantees of asset cash flows or servicing arrangements. The presence of any of these terms and conditions requires us to determine whether control of the underlying asset has been transferred to the buyer, and whether we no longer have significant ownership risk in the asset, both of which are required for a sale and resulting gain or loss to be recognized.
Total loss write-offs	Total loss write-offs Total loss write-offs result from the loss of an asset because of an unforeseen event (for example, an airplane crash incident, physical loss by wrongful deprivation, asset seizure, or other loss event). These events may be insured through the lessee’s insurance policies where we are named as the insured, and under our own insurance policies where the lessee’s insurance policy fails to indemnify us. We recognize an insurance receivable to the extent we have a claim from a loss from a total loss write-off event and the likelihood of recovering such loss or portion of the loss is probable at the balance sheet date.
Unusual or infrequently occurring events or transactions	Unusual or infrequently occurring events or transactions A material event or transaction that we consider to be unusual in nature or that is expected to occur infrequently, or both, is reported separately in our Consolidated Income Statements, gross of income taxes.
Allowance for credit losses	Allowance for credit losses We are exposed to credit losses on our investment in finance leases, net, and loans and notes receivable (collectively “Financing Receivables”). The credit exposure of our Financing Receivables reflects the risk that our customers fail to meet their payment obligations and the risk that the aircraft value in an investment in finance lease, net is less than the unguaranteed residual value. We estimate the expected risk of loss of our Financing Receivables over the remaining life using a probability of default and net exposure analysis. The probability of default is estimated based on historical cumulative default data, adjusted for current conditions of similarly risk-rated counterparties over the contractual term. The net exposure is estimated based on the exposure, net of the estimated aircraft value in the instance of investment in finance leases, net, and other cash collateral, including security deposits and maintenance-related deposits, over the contractual term. We also estimate the expected risk of loss on the unguaranteed residual value based on the estimated value of the aircraft at the expiry of the finance lease.
Share-based compensation	Share-based compensation Employees may receive AerCap share-based awards, consisting of restricted stock units or restricted stock. Share-based compensation expense is determined by reference to the fair value of the restricted stock units or restricted stock on the grant date and is recognized on a straight-line basis over the requisite service period. Share-based compensation expense is classified in selling, general and administrative expenses.
Foreign currency	Foreign currency Foreign currency transactions are translated into U.S. dollars at the exchange rate prevailing at the time of the transaction. Receivables or payables denominated in foreign currencies are remeasured into U.S. dollars at the exchange rate prevailing at the balance sheet date. All resulting exchange gains and losses are recorded in selling, general and administrative expenses in our Consolidated Income Statements. Foreign currency exchange gains or losses on our investments at fair value are recorded in gain (loss) on investments at fair value in our Consolidated Income Statements.
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 variable interest entity (“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 VIE’s 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.
Earnings per share	Earnings per share Basic Earnings (Loss) Per Share (“EPS”) is computed by dividing income available to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. For the purposes of calculating diluted EPS, the denominator includes both the weighted average number of ordinary shares outstanding during the period and the weighted average number of potentially dilutive ordinary shares, such as restricted stock units, restricted stock and stock options. In a period where a net loss is recognized, the denominator of the dilutive EPS calculation does not include potentially dilutive ordinary shares.
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 flight equipment.
Recent accounting standards adopted during the years December 31, 2022 & 2020 and future application of accounting standards	Accounting standards adopted during the year ended December 31, 2022 Reference Rate Reform In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASC 848”). ASC 848 provided temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to reduce the financial reporting burden in light of the market transition from London Interbank Offered Rates (“LIBOR”) and other reference interest rates to alternative reference rates. During the fourth quarter of 2022, we adopted ASC 848 (effective October 1, 2022). The adoption has not and is not expected to have a material impact on our financial statements. We have certain debt instruments, derivative contracts, and leases that reference LIBOR. LIBOR is a benchmark interest rate calculated based on information contributed by a panel of large international banks. LIBOR’s administrator announced in March 2021 that it intends to stop publishing the Overnight, 1-month, 3-month, 6-month and 12-month USD LIBOR settings after June 30, 2023. In anticipation of that cessation, we commenced the transition of our LIBOR based instruments, contracts and leases to Secured Overnight Financing Rate (“SOFR”) in October 2022 and expect to conclude the transition by June 2023. Topic 848 provides several optional expedients that permit an entity to not apply otherwise applicable U.S. GAAP to contracts or transactions modified or otherwise affected due to reference rate reform, provided the conditions for the respective expedients are met. Before we commenced the transition of these instruments, contracts and leases to reference SOFR instead of LIBOR, we applied optional expedients under Topic 848. When we modified those agreements, we applied optional expedients that allowed us to (a) account for the contract modifications as continuations of the existing contracts without further accounting assessment that might otherwise be required and (b) continue cash flow hedging relationships without dedesignation when changes are made to hedge documentation, contractual terms of the hedging instrument or forecasted transaction, hedged risk, and effectiveness assessment method. As of December 31, 2022, we had $3.2 billion of floating rate debt outstanding linked to a SOFR index, and $5.1 billion of floating rate debt outstanding linked to either one three six one three six In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which extends the sunset date of Topic 848 from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the optional expedients in Topic 848. The adoption of ASU 2022-06, which was effective upon issuance, did not have a material effect on the Company’s consolidated financial statements. Recent accounting standards adopted during the year ended December 31, 2020: Allowance for credit losses In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (“ASC 326”). ASC 326 replaced the incurred loss methodology with an expected loss methodology referred to as the current expected credit loss (“CECL”) methodology. The CECL methodology utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses for most financial assets measured at amortized cost and certain other instruments, including loan and other receivables and investment in finance and sales-type leases, net. Our investment in finance and sales-type leases, net and notes receivable are the primary financial assets within the scope of ASC 326. Our trade receivables related to aircraft operating leases are not within the scope of ASC 326. On January 1, 2020, we adopted ASC 326 under a modified retrospective approach. The cumulative effect of measuring the allowance for credit losses under the CECL methodology, as a result of adopting ASC 326 on January 1, 2020, was an increase to the allowance for credit losses of $30.3 million and a decrease to retained earnings of $25.8 million, net of tax. Accounting for lease concessions related to the effects of the Covid-19 pandemic In April 2020, the FASB issued an interpretive guidance Staff Q&A Accounting for lease concessions related to the effects of the Covid-19 pandemic (the “Q&A”). The Q&A is applicable to companies whose leases are affected by the economic disruptions caused by the Covid-19 pandemic. The Q&A provides that a company may elect to account for lease concessions as though those concessions existed regardless of whether the enforceable rights and obligations for the concessions explicitly exist in the contract. As a result, an entity is not required to analyze each contract to determine whether enforceable rights and obligations for concessions exist in the contract and can elect to apply or not apply the lease modification guidance in ASC 842, Leases, to those contracts. This election is available for concessions that result in the total payments required by the modified contract being substantially the same as or less than the total payments required by the original contract. Effective beginning in the period ended March 31, 2020, we have elected to account for lease concessions related to the effects of the Covid-19 pandemic consistently with how those concessions would be accounted for under ASC 842 as though enforceable rights and obligations for those concessions existed (regardless of whether those enforceable rights and obligations for the concessions explicitly exist in the contract). This election is available for concessions related to the effects of the Covid-19 pandemic that do not result in a substantial increase in the rights of the lessor or the obligations of the lessee.
