Basic net income per share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common shares and potential common shares outstanding during the period. Potential common shares include the dilutive effects of outstanding stock options, vested and non-vested restricted stock, performance share units, and shares issued under the employee stock purchase plan, except where their inclusion would be anti-dilutive.

Anti-dilutive shares include non-vested restricted stock and outstanding stock options for which the sum of the assumed proceeds, including unrecognized compensation expense, exceeds the average stock price during the periods presented. Anti-dilutive shares associated with our stock options relate to those stock options with an exercise price higher than the average market value of our stock during the periods presented.
