Net Loss per Common Share Basic loss per share is calculated based upon the net loss available to common shareholders divided by the weighted average number of common shares outstanding during the period. Diluted loss per share is calculated after adjusting the denominator of the basic earnings per share computation for the effects of all dilutive potential common shares outstanding during the period. The dilutive effects of preferred stock, options and warrants and their equivalents are computed using the treasury stock method. The total number of shares of common stock issuable upon exercise of warrants, stock option grants and equity awards were 4,595,990 shares for the six-month period ended June 30, 2019.

The total number of shares of common stock issuable upon exercise of warrants and equity awards was 6,255,757 shares for the three-month and six-month periods ended June 30, 2018.
