Net Loss Per Common Share

Note 5. 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 6,255,757 and 1,284,154 shares for the three and six-month periods ended June 30, 2018 and 2017, respectively. For the three and six month periods ended June 30, 2018 and 2017, diluted loss per common share was the same as basic loss per common share as all options and all warrants that were exercisable into shares of the Company’s common stock were excluded from the calculation of diluted earnings attributable to common shareholders per common share as their effect would have been anti-dilutive.
