Earnings Per Share [Abstract]  
Earnings per Common Share
Note 2Earnings per Common Share
Basic earnings per common share is computed using the weighted average number of common shares outstanding, including vested unissued participating restricted stock units. Diluted earnings per common share is computed using the weighted average number of common and dilutive potential common shares outstanding.
For the Company, dilutive potential common shares consist of outstanding stock options, unvested
non-participating restricted stock units and contingently issuable performance stock awards. The effect of dilutive potential common shares does not include options with an anti-dilutive effect on earnings per common share because their exercise prices exceed the average market price of Allstate common shares during the period or for which the unrecognized compensation cost would have an anti-dilutive effect.
