Note I - Computation of Earnings Per Share

Basic earnings per share were computed by dividing net income by the weighted-average number of common shares outstanding for each respective period.  Diluted earnings per share were calculated by dividing net income by the weighted-average of all potentially dilutive common shares that were outstanding during the years presented.

The calculation of basic and diluted earnings per share for the year ended December 31 was as follows:

For the year ended December 31, 2020, 2019 and 2018, 37,919, 15,041 and 260 stock options, respectively, were excluded from the calculation of diluted earnings per share as the effect would have been anti-dilutive.
