Net Income Per Share
5. Net Income Per Share

Basic net income per share is calculated using the weighted-average number of common shares outstanding during the period. Diluted net income per share is calculated using the sum of weighted-average number of common shares outstanding during the period, plus the dilutive effect of shares issuable through stock options.

The shares used in calculating basic and diluted net income per share for the condensed consolidated statements of operations included within this report are reconciled as follows (in thousands) :

Weighted average shares outstanding for basic net income per share

Dilutive effect of stock options and restricted stock units

Weighted average shares outstanding for diluted net income per share
  22,486   22,679   23,324   22,969 

Options covering approximately 3.7 million and 3.4 million shares for the three month periods ended November 30, 2011 and 2010, and approximately 1.8 million and 1.6 million shares for the nine month periods ended November 30, 2011 and 2010, respectively, were excluded from the computation of average shares outstanding for diluted net income per share because their effects were antidilutive.
