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 0.6 million and 0.7 million as of
June 30, 2019 and 2018, respectively.
