Net Income Per Share |
Net Income Per Share | (6) Net Income Per Share Basic net income per common share (“Basic EPS”) is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per common share (“Diluted EPS”) reflects the potential dilution that could occur if stock options or other contracts to issue common stock were exercised or converted into common stock. The computation of Diluted EPS does not assume exercise or conversion of securities that would have an anti-dilutive effect on net loss per common share. The following is a reconciliation of the numerator and denominator of Basic EPS to the numerator and denominator of Diluted EPS for the three months ended March 31, 2013 and 2012:
|  | Three Months Ended March 31, |
|  | 2013 |  | 2012 |
Net income |  | $ | 4,864 |  | $ | 7,228 |
Basic weighted average shares outstanding |  | 15,822 |  | 15,578 |
Basic net income per common share |  | $ | 0.31 |  | $ | 0.46 |
Diluted shares outstanding |  |  |  |  |
Basic weighted average shares outstanding |  | 15,822 |  | 15,578 |
Stock options |  | 134 |  | 268 |
Diluted weighted average shares outstanding |  | 15,956 |  | 15,846 |
Diluted net income per common share |  | $ | 0.30 |  | $ | 0.46 |
Potentially dilutive shares excluded from diluted per share amounts: |  |  |  |  |
Stock options |  | 45 |  | 251 |
Potentially anti-dilutive shares excluded from diluted per share amounts: |  |  |  |  |
Stock options |  | 1,124 |  | 135 |
Potentially dilutive shares excluded from diluted-per-share amounts include performance-based options to purchase shares of common stock for which certain earnings metrics have not been achieved. Potentially anti-dilutive shares excluded from diluted-per-share amounts include both non-qualified stock options and unearned performance-based options to purchase shares of common stock with exercise prices greater than the weighted-average share price during the period and shares that would be anti-dilutive to the computation of diluted net income (loss) per share for the three months ended March 31, 2013 and 2012.
