5. Net Income Per Common Share

Basic earnings 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	46,808	47,920	47,051	47,833
Effect of dilutive stock options and restricted stock	287	417	285	484
Diluted weighted average shares outstanding	47,095	48,337	47,336	48,317

Diluted weighted average shares outstanding excludes the incremental effect of unvested restricted stock and shares that would be issued upon the assumed exercise of stock options in accordance with the treasury stock method. For the three month periods ended September 30, 2020 and 2019, approximately 79 and 0, respectively, and for the nine month periods ended September 30, 2020 and 2019, approximately 148 and 0, respectively, of the Company’s restricted stock awards 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.
