2.  Earnings per Common Share

 

Basic earnings per common share is computed using the weighted average number of common shares outstanding, including unvested 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 and unvested non-participating restricted stock units and contingently issuable performance stock awards.

 

The computation of basic and diluted earnings per common share is presented in the following table.

The effect of dilutive potential common shares does not include the effect of 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.  Options to purchase 8.4 million and 17.8 million Allstate common shares, with exercise prices ranging from $41.16 to $62.42 and $31.41 to $62.84, were outstanding for the three-month periods ended September 30, 2013 and 2012, respectively, but were not included in the computation of diluted earnings per common share in those periods.  Options to purchase 13.0 million and 22.1 million Allstate common shares, with exercise prices ranging from $39.05 to $62.42 and $26.56 to $62.84, were outstanding for the nine-month periods ended September 30, 2013 and 2012, respectively, but were not included in the computation of diluted earnings per common share in those periods.
