Basis of Presentation - Consolidation

The accompanying unaudited condensed consolidated financial statements of AAG should be read in conjunction with the consolidated financial statements contained in AAG's Annual Report on Form 10-K for the year ended December 31, 2013. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Principal subsidiaries include American and, effective December 9, 2013, US Airways Group. Because the Merger did not occur until December 2013, the unaudited condensed consolidated financial statements presented do not include the accounts of US Airways Group for the three months ended March 31, 2013. Certain prior period amounts have been reclassified to conform to the current year financial statement presentation as described below. All significant intercompany transactions have been eliminated.

Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the unaudited condensed consolidated financial statements for the interim periods presented. The preparation of financial statements in accordance with accounting principles generally accepted in the United States requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, impairment of goodwill, impairment of long-lived and intangible assets, the frequent traveler programs, pensions and retiree medical and other benefits and the deferred tax asset valuation allowance.

Chapter 11 Matters

In accordance with U.S. Generally Accepted Accounting Principles (GAAP), the Debtors (as defined in Note 2 below) applied ASC 852 "Reorganizations" (ASC 852) in preparing the condensed consolidated financial statements for periods subsequent to the Chapter 11 Cases (as defined in Note 2 below). ASC 852 requires that the financial statements distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the business. Accordingly, certain revenues, expenses (including professional fees), realized gains and losses and provisions for losses that are realized or incurred in the Chapter 11 Cases for the 2013 period are recorded in Reorganization items, net on the accompanying unaudited condensed consolidated statement of operations.
