Earnings Per Share
Note 7 − Earnings Per Share

Basic earnings per share are based on the weighted average number of shares outstanding for a period. Diluted earnings per share are based upon the weighted average number of shares and potentially dilutive common shares outstanding. Potential common shares outstanding principally include stock options, under our stock plan and warrants. During 2019, and 2018 we incurred losses; therefore, the effect of any common stock equivalent would be anti-dilutive during those periods.

The table below sets forth the basic and diluted loss per share calculations:
