Note 9. Earnings per Share Reconciliation of the numerators and denominators of the earnings per share calculations  — The share count for diluted earnings per share is computed on the basis of the weighted-average number of common shares  outstanding plus the effects of dilutive common stock equivalents (CSEs) outstanding during the period.  We excluded 0.3  million and 1.1 million CSEs from the calculations of diluted earnings per share for the years  2013 and 2012 as the effect of  including them would have been anti-dilutive. In addition, we excluded CSEs that satisfied the definition of potentially dilutive  shares of 1.5 million for 2013 since there was no net income available to common stockholders for this period. We excluded 12.2 million shares related to the assumed conversion of our Series  A preferred stock for 2013 and  39.9  million shares related to the assumed conversion of our Series B preferred stock for 2013, along with the adjustment for the  related dividend requirements, as the conversions would have been anti-dilutive for the period. Our 2012 Omnibus Incentive Plan (the Plan), as approved by our stockholders, authorizes the grant of stock options, stock  appreciation rights (SARs), RSUs and performance share units (PSUs) through  April 2022. Cash-settled awards do not count  against the maximum aggregate number . At December 31, 2014, there were 5.0 million shares available for future grants. 59 Options SARs RSUs PSUs Weighted- Average Weighted- Average Weighted- Average Grant-Date Weighted- Average Grant-Date Outstanding at Shares Exercise Price Shares Exercise Price Shares Fair  Value Shares Fair  Value December 31, 2013 2.6 $ 13.85 0.5 $ 15.46 1.3 $ 16.29 — $ — Granted 0.7 21.20 0.3 24.36 Exercised or vested (0.6) 11.48 (0.1) 16.49 (0.4) 16.99 Forfeited or expired (0.1) 15.89 (0.1) 14.91 December 31, 2014 1.9 $ 14.46 0.4 $ 15.18 1.5 $ 18.18 0.3 $ 24.36 2014 2013 2012 Income from continuing operations $ 343 $ 261 $ 315 Less: Noncontrolling interests 9 16 15 Less: Preferred stock dividend requirements 7 25 31 Less: Preferred stock redemption premium 232 Income (loss) from continuing operations available to common stockholders - Numerator basic 327 (12) 269 Preferred stock dividend requirements 7 31 Numerator diluted $ 334 $ (12) $ 300 Net income (loss) available to common stockholders - Numerator basic $ 312 $ (13) $ 269 Preferred stock dividend requirements 7 31 Numerator diluted $ 319 $ (13) $ 300 Weighted-average number of shares outstanding - Denominator basic 158.0 146.4 148.0 Employee compensation-related shares, including stock options 1.2 2.0 Conversion of preferred stock 14.3 64.7 Denominator diluted 173.5 146.4 214.7 Note 10.
