14.EARNINGS PER SHARE

Basic earnings per share are determined by dividing net income by the weighted-average common shares outstanding during the year. The calculation of diluted earnings per share includes the dilutive effect of unexercised non-qualified stock options and non-vested stock units. The computation of weighted average dilutive shares outstanding excluded a nominal amount of anti-dilutive non-qualified stock options for each of the years 2019, 2018 and 2017.

The denominators used to compute basic and diluted earnings per share for the years ended December 31, 2019, 2018 and 2017 are as follows:
