NOTE 7 - Net Income Per Share

There were no material adjustments to net income in calculating diluted net income per share. The table below reconciles basic weighted shares outstanding to diluted weighted average shares outstanding (in thousands):

                                                           
              Three Months Ended January 31,           Six Months Ended January 31,        
              2012           2011           2012           2011        
  Basic weighted average shares outstanding           64,153           81,240           64,935           82,492        
  Effect of dilutive securities - stock options           1,642           715           1,413           688        
  Diluted weighted average shares outstanding           65,795           81,955           66,348           83,180        

Excluded from the dilutive earnings per share calculation were 1,155,000 and 1,575,097 stock options for the three months ended January 31, 2012 and 2011, respectively, because their effect would have been anti-dilutive and excluded from the dilutive earnings per share calculation were 1,133,215 and 3,962,032 stock options for the six months ended January 31, 2012 and 2011, respectively, because their effect would have been anti-dilutive.
