Net Income Per Common Share [Abstract]

3. Net Income Per Common Share

Basic net income per common share is calculated by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per common share reflects the assumed conversion of all potentially dilutive securities, consisting of stock options, for which the estimated fair value exceeds the exercise price, less shares which could have been purchased with the related proceeds, unless anti-dilutive. For employee equity awards, repurchased shares are also included for any unearned compensation adjusted for tax.

The table below reflects the calculation of the weighted average number of common shares outstanding, on an as if converted basis, used in computing basic and diluted earnings per common share.

Denominator:

Basic common shares outstanding		44,658		45,724		45,122		45,699
Effect of dilutive stock options and restricted stock		360		833		429		742

Diluted common shares outstanding		45,018		46,557		45,551		46,441

Diluted weighted average shares outstanding exclude the incremental effect of shares that would be issued upon the assumed exercise of stock options. For the six months ended June 30, 2011 and 2010, approximately 2,735 and 690, respectively, of the University’s stock options outstanding were excluded from the calculation of diluted earnings per share as their inclusion would have been anti-dilutive. These options could be dilutive in the future.
