Note 3 – Loss Per Share Available to Common Stockholders

Basic loss per share is computed by dividing the loss available to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Basic loss per share excludes potential dilution of securities or other contracts to issue shares of common stock. Diluted loss per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the income of the Company. For each of the three and six months ended June 30, 2020 and 2019, basic net loss per share available to common stockholders is the same as diluted loss per share.

The following table sets forth the computation of the Company’s basic and diluted net loss per share during the three and six months ended June 30, 2020 and 2019:

Diluted loss per share excludes all dilutive potential shares if their effect is anti-dilutive. As of June 30, 2020 and 2019, the following potential common stock equivalents were excluded from the calculation of diluted loss per share as their effect was anti-dilutive:

The terms of certain of the warrants, convertible preferred stock and convertible debentures issued by the Company provide for reductions in the per share exercise prices of the warrants and the per share conversion prices of the debentures and preferred stock (if applicable and subject to a floor in certain cases), in the event that the Company issues common stock or common stock equivalents (as that term is defined in the agreements) at an effective exercise/conversion price that is less than the then exercise/conversion prices of the outstanding warrants, preferred stock or debentures, as the case may be. In addition, many of these equity-based securities contain exercise or conversion prices that vary based upon the price of the Company’s common stock on the date of exercise/conversion (see Notes 11, 12 and 13). These provisions have resulted in significant dilution of the Company’s common stock and have given rise to reverse splits of the Company’s common stock, including the Reverse Stock Split effected on July 31, 2020, which is more fully discussed in Note 1.
