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   Six Months Ended
    June 30,   June 30,

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 both the
three
- and
six
-month periods ended
June 30, 2019
, the number of stock awards excluded from the computation of diluted earnings per share for this reason was
16,536
.
For the
three
- and
six
-month periods ended
June 
30,
2018
, the number of stock awards excluded from the computation of diluted earnings per share for this reason was
24,280
and
25,344,
respectively.
