Accounting Policies [Abstract]
General	General Our Condensed 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. Unconsolidated investments where we have significant influence are reported using the equity method of accounting. Our Condensed Consolidated Financial Statements are stated in U.S. dollars, which is our functional currency. Our interim financial statements have been prepared pursuant to the rules of the U.S. Securities and Exchange Commission (“SEC”) and U.S. GAAP for interim financial reporting, and reflect all adjustments that are necessary to fairly state the results for the interim periods presented.

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 June 30, 2023, we had $5.8 billion of floating rate debt outstanding linked to a SOFR index, and $3.1 billion of floating rate debt outstanding linked to three-month U.S. dollar LIBOR. As of June 30, 2023, we had approximately $3.1 billion notional amount of floating rate derivatives outstanding linked to a SOFR index and $3.1 billion notional amount of floating rate derivatives outstanding linked to either one-month or three-month U.S. dollar LIBOR. 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, has not and is not expected to have a material impact on our financial statements.

Our Condensed 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.

Unconsolidated investments where we have significant influence are reported using the equity method of accounting.

Our Condensed Consolidated Financial Statements are stated in U.S. dollars, which is our functional currency.

Our interim financial statements have been prepared pursuant to the rules of the U.S. Securities and Exchange Commission (“SEC”) and U.S. GAAP for interim financial reporting, and reflect all adjustments that are necessary to fairly state the results for the interim periods presented. Certain information and footnote disclosures required by U.S. GAAP for complete annual financial statements have been omitted and, therefore, our interim financial statements should be read in conjunction with our Annual Report on Form 20-F for the year ended December 31, 2022, filed with the SEC on March 2, 2023. The results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of those for a full fiscal year.

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.

Use of estimates

The preparation of Condensed 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 the reported carrying values of flight equipment, intangible assets, investment in finance leases, net, investments, trade receivables, notes receivables, deferred tax assets, income tax accruals and maintenance liabilities. Actual results may differ from our estimates under different conditions, sometimes materially.

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.
