Net Loss Per Common Share

Basic net loss per common share is calculated by dividing the net loss by the weighted average number of outstanding common shares during the period. Diluted net loss per common share includes the weighted average dilutive effect of stock options and warrants. Potential common shares outstanding as of March 31, 2021 and 2020:

	March 31, 2021		March 31, 2020
Warrants		0		0
Options		1,987,000		2,192,000
Total		1,987,000		2,192,000

The number of securities not included in the diluted net loss per share for the First Quarter 2021 and the First Quarter 2020 was 1,987,000 and 2,192,000, respectively, as their effect would have been anti-dilutive due to the net loss in the First Quarter 2021 and First Quarter 2020.
