EARNINGS PER-SHARE |
EARNINGS PER-SHARE | 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 2018, 2017, and 2016. The denominator used to compute basic and diluted earnings per share for the years ended December 31, 2018, 2017 and 2016 are as follows:
|  | Year Ended December 31, 2018 |  | Year Ended December 31, 2017 |  | Year Ended December 31, 2016 |
