(1)
Excludes 1.1 million and 4.0 million shares of unvested restricted stock or restricted stock units and stock options for the years ended December 31, 2014 and 2013, respectively, because including the effect would have been anti-dilutive.
(2)
The effect of unvested restricted stock or restricted stock units and stock options has not been included in the calculation of shares outstanding for diluted EPS for the year ended December 31, 2012, as their effect would have been anti-dilutive. Had we recognized income from continuing operations for that year, incremental shares attributable to the assumed vesting of unvested restricted stock and restricted stock units and the assumed exercise of outstanding stock options would have increased diluted weighted-averages shares outstanding by 0.7 million shares for the year ended December 31, 2012.
(3)
The numerator includes an adjustment of $20 million related to the repurchase of preferred shares of a now wholly-owned subsidiary, which reduces net income (loss) for purposes of earnings per share for the year ended December 31, 2013. The subsidiary is part of our continuing operations. See Note 16, "Related Party Transaction," for additional information.
