Basic and Diluted Net Income (Loss) Per Common Share 
2. Basic and Diluted Net Income (Loss) per
Common Share
Basic net income (loss) per share is calculated
by dividing the net income (loss) by the weightedaverage number of common shares outstanding for the period, without consideration
for common stock equivalents. Diluted net loss per share is calculated by dividing the net loss by the weightedaverage number
of common share equivalents outstanding for the period that are determined to be dilutive. Common stock equivalents are primarily
comprised of preferred stock and warrants for the purchase of common stock. For the three months ended September 30, 2020, there
is no difference in the number of shares and net loss used to calculate basic and diluted shares outstanding because their effect
would have been antidilutive. The Company had potentially dilutive securities, totaling approximately 1.6 million and 0.5
million as of September 30, 2020 and 2019, respectively.
