NET INCOME PER SHARE
NOTE 14.  NET INCOME PER SHARE

The following is a reconciliation of the weighted average number of common shares outstanding used in calculating basic and diluted net income per share (in thousands, except share and per share data):

Numerator:
         
  Net income
 $27,459  $13,091  $14,537 
Denominator:
            
  Weighted average common shares outstanding - basic
  21,946,000   22,084,000   22,365,000 
  Weighted average effect of dilutive securities:
            
    Stock options
  89,000   130,000   294,000 
    Restricted stock units
  318,000   230,000   197,000 
    Warrants
  28,000   18,000   2,000 
  Weighted average common shares outstanding - diluted
  22,381,000   22,462,000   22,858,000 
Net income per share:
            
  Basic net income per share
 $1.25  $0.59  $0.65 
  Diluted net income per share
 $1.23  $0.58  $0.64 

Stock options and warrants are excluded from the computation of diluted weighted average shares outstanding if the exercise price of the stock options and warrants is greater than the average market price of our common stock during the period because the inclusion of these stock options and warrants would be antidilutive to net income per share.  There were no stock options and warrants excluded from the computation of diluted weighted average shares outstanding during fiscal 2013, 2012 and 2011.

We excluded the following restricted stock units from the computation of diluted weighted average shares outstanding because the inclusion of these awards would be antidilutive to net income per share:

   
Year Ended March 31,
 
   
2013
  
2012
  
2011
 
Weighted average number of shares underlying antidilutive restricted stock units
  2,000   267,000   213,000 

If the performance criteria for our restricted stock unit awards (performance vesting) are achieved, these awards will be considered outstanding for the purpose of computing diluted net income per share if the effect is dilutive.  Starting with the first quarter of fiscal 2013, we granted 21,000 restricted stock unit awards (performance vesting), with vesting based on the achievement of certain pre­established corporate annual performance related goals.  The performance criteria for our restricted stock unit awards (performance vesting) were achieved during fiscal 2013 and were included in the computation of diluted weighted average shares outstanding.  There were no restricted stock unit awards (performance vesting) excluded from the computation of diluted weighted average shares outstanding during fiscal 2013.
