The following is a reconciliation of the weighted average common shares outstanding used for the computation of basic and diluted net income per common share:

Basic weighted average shares outstanding

      154,025,589         166,896,322         168,053,502   

Effect of dilutive options, non-vested shares and stock appreciation rights

      2,165,700         3,437,228         3,176,743   
  

 

 

     

 

 

     

 

 

  

Diluted weighted average common shares outstanding

For the fiscal years ended January 31, 2012, 2011 and 2010, awards to purchase 3,836,838 common shares ranging in price from $26.85 to $39.58, 1,324,238 awards to purchase common shares ranging in price from $32.89 to $39.58 and 4,331,650 awards to purchase common shares ranging in price from $16.58 to $37.51, were excluded from the calculation of diluted net income per common share because the impact would be anti-dilutive.

As of January 31, 2012, 2,533,950 contingently issuable awards were excluded from the calculation of diluted net income per common share as they did not meet certain performance criteria.
