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 |

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 |

Denominator diluted | 173.5 |  |  | 146.4 |  |  | 214.7 |
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.
