Earnings Per Share [Abstract] |
Earnings per Common Share | Earnings per Share Basic income per share is based on the weighted-average number of shares of common stock outstanding. Diluted income per share is based upon the weighted-average number of shares of common stock outstanding plus all potentially dilutive securities that were assumed to be converted into common shares at the beginning of the period under the treasury stock method. This method requires the effect of potentially dilutive common stock equivalents be excluded from the calculation of diluted earnings per share for the periods in which net losses are reported because the effect is anti-dilutive.
