Earnings Per Share |
Earnings Per Share | 13. Earnings Per Share Basic earnings per share (EPS) excludes dilution and is computed by dividing net income available for common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS is computed by dividing net income by the weighted average number of common shares outstanding and potential common stock equivalent shares for the period. The Company includes as potential common shares the weighted average dilutive effects of outstanding stock options and restricted stock units using the treasury stock method. The following table sets forth a reconciliation of the denominators for basic and diluted earnings per share:
|  | Three Months Ended |  | Six Months Ended |
|  | March 31, 2014 |  | March 31, 2013 |  | March 31, 2014 |  | March 31, 2013 |
|  | (in millions) |
Denominator for basic earnings per share |  | 97.0 |  | 100.4 |  | 96.7 |  | 102.8 |
Potential common shares |  | 1.3 |  | 1.4 |  | 1.3 |  | 1.1 |
Denominator for diluted earnings per share |  | 98.3 |  | 101.8 |  | 98.0 |  | 103.9 |
EPS includes the effect of repurchased shares, which are discussed in Note 3 herein. For the six months ended March 31, 2014 and 2013, options excluded from the calculation of potential common shares were not significant.
