4. 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 and restricted stock awards, 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 weighted average shares outstanding		46,004		46,012		45,813		45,901
Effect of dilutive stock options and restricted stock		986		1,251		1,112		1,332

Diluted weighted average shares outstanding		46,990		47,263		46,925		47,233

Diluted weighted average shares outstanding exclude the incremental effect of shares that would be issued upon the assumed exercise of stock options and vesting of restricted stock. For the six months ended June 30, 2016 and 2015, approximately 434 and 345, 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 and restricted stock awards could be dilutive in the future.
