Basic earnings per share$1.79  $1.31  
Diluted earnings per share$1.78  $1.30  
Anti-dilutive options are not included in the computation of diluted earnings per share because the options’ exercise price was greater than the average market price of the common shares and therefore, the effect would have been anti-dilutive. Anti-dilutive options were not significant for any of the periods shown above.
