[1] To conform to current year presentation, certain operating revenue and expenses in prior years have been reclassified. As a result, prior year amounts may not agree to the amounts previously reported. See Note 4 for additional information.

[2] The Company’s weighted average diluted shares outstanding for all quarters presented include the weighted effect of shares outstanding for both the pre and post-merger periods. The shares outstanding for the pre-merger periods (January 1, 2012 through December 8, 2013) consist only of the AMR common stock formerly traded under the symbol: "AAMRQ". In accordance with GAAP, these former AAMRQ shares have been adjusted for all periods presented to retrospectively reflect the two initial distributions made to date pursuant to the Company’s Plan, whereby holders of AAMRQ received shares of AAG Common Stock on the Effective Date, January 9, 2014 and February 10, 2014. The shares outstanding for the 23 day post-merger period (December 9, 2013 through December 31, 2013) include the full amount of shares to be issued pursuant to the Plan over the 120 day distribution period adjusted for the approximate 13 million shares withheld by the Company in satisfaction of employee tax obligations.Former AAMRQ holders as of the Effective Date have and may in the future receive additional distributions based on the trading price of AAL common stock during the remaining 120 day period after the effective date and the total amount of allowed claims, in accordance with the terms of the Plan. Accordingly, the Company’s common shares outstanding and related GAAP basic and diluted EPS reported herein for all periods presented may change in the future, including amounts reported herein, to reflect additional retrospective adjustments for future common stock distributions to former holders of AAMRQ.

[3] The year ended December 31, 2013 does not include the impact of post-petition interest recorded in first quarter of 2013. If such amounts were included, results would have been anti-dilutive and conversion would not have been assumed.
