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 June
30, 2021, 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 1.8 million
and 1.3 million as of June 30, 2021 and 2020, respectively.
