Basic earnings per share is determined by dividing net income by the weighted-average common shares outstanding during the period. The calculation of diluted earnings per share includes the dilutive effect of unexercised non-qualified stock options and non-vested restricted stock units. The computation of basic and diluted earnings per share for the three and nine months ended September 30, 2019 and 2018, are as follows:
