Earnings Per Share [Abstract]  
Earnings per Common Share
Earnings per Common Share

Basic earnings per share is calculated based upon the weighted average number of outstanding common shares for the period, plus the effect of deferred vested shares. Diluted earnings per share is calculated consistent with the basic earnings per share calculation plus the effect of dilutive unissued common shares related to stock-based employee compensation programs. For all periods presented, anti-dilutive stock options were excluded from the calculation of diluted earnings per share. Cumulative treasury stock acquired, less cumulative shares reissued, have been excluded in determining the average number of shares outstanding.

Earnings per share are calculated as follows (share information in thousands):
