NET INCOME PER SHARE - Note 5

5. NET INCOME PER SHARE

 

Basic net income per share is computed by dividing net income available to common stockholders (numerator) by the weighted average number of vested, unrestricted common shares outstanding during the period (denominator). Diluted net income per share is computed on the basis of the weighted average number of shares of common stock outstanding plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include shares issuable upon exercise of outstanding stock options and under the ESPP.
