Earnings Per Share [Abstract] |
Earnings Per Share | Earnings (Loss) Per Share Basic earnings per share is calculated by dividing income available to common shareholders by the weighted average number of common shares outstanding and restricted stock grants that vested or are likely to vest during the period. Diluted earnings per share is calculated by dividing income available to common shareholders by the weighted average number of basic common shares outstanding, adjusted to reflect potentially dilutive securities. Diluted earnings per share is calculated using the treasury stock method.
