[1] The sum of the amounts for the four quarters does not equal the total for the year due to rounding.

[2] Because earnings (loss) per share amounts are calculated using the weighted-average number of common and dilutive common equivalent shares outstanding during each quarter, the sum of the per-share amounts for the four quarters may not equal the total earnings (loss) per share amounts for the year.

[3] In April 2011, the Company obtained $2.2 billion of new debt financing. A portion of the proceeds from the new debt financing was used to purchase 26,150,000 shares of ACI’s common stock held by the Estate. The share repurchase reduced the Company’s outstanding shares by approximately 45%. The reduction in the Company’s weighted-average shares outstanding from the Repurchase Transaction benefited 2011 diluted earnings per share by $0.54.
