Basic and Diluted Net Loss Per Common Share 
2. Basic and Diluted Net Loss per Common
Share
Basic net loss per share is calculated by dividing
the net 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,
warrants for the purchase of common stock and stock options. The Company had potentially dilutive securities, totaling approximately
0.5 million and 0.8 million as of September 30, 2019 and 2018, respectively.
