Income Per Share
 
Basic income per share is based on the weighted average number of shares of common stock outstanding. Diluted income per share is based upon the weighted average number of common shares outstanding and dilutive common stock equivalent shares outstanding during each period.
 
The weighted average number of shares used to compute basic and diluted net income per share consisted of the following (in thousands):
 
    Three Months Ended
March 31,
    2018   2017
Basic weighted average common shares outstanding    
7,300
     
7,216
 
Weighted average common equivalent shares due to stock options and RSUs    
78
     
81
 
Diluted weighted average common shares outstanding    
7,378
     
7,297
 
 
The computation of diluted earnings per share excludes the effect of the potential exercise of stock awards, including stock options, when the average market price of the common stock is lower than the exercise price of the related options during the period. These outstanding stock awards are
not
included in the computation of diluted income per share because the effect would be antidilutive. For the
three
-month periods ended
March 
31,
2018
and
2017
, the number of stock awards excluded from the computation of diluted earnings per share for this reason was
15,000
and
35,193,
respectively.
