General
Our Consolidated Financial Statements are presented in accordance with U.S. GAAP.
We consolidate all companies in which we have direct and indirect legal or effective control and all VIEs for which we are deemed the PB under 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 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.
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 the reported carrying values of flight equipment, intangible assets, net investment in finance and sales-type leases, investments, trade receivables and notes receivable, deferred income tax assets and accruals and reserves. Actual results may differ from our estimates under different conditions, sometimes materially.
