NOTE 10. EARNINGS PER SHARE

Basic and diluted net income per share are computed by dividing net income by the weighted-average number of common shares outstanding. Diluted net income per share reflects the dilutive effect of stock-based compensation.

The computation of dilutive shares from stock-based compensation does not include 5.6 million shares and 2.5 million shares for the three months ended March 31, 2019 and 2018, respectively, as their effect would have been anti-dilutive.
