Net loss per common share:
Net Loss per Common Share	Net loss per common share is computed based on the weighted-average number of common shares outstanding and, when appropriate, dilutive potential common stock outstanding during the period. Stock options, convertible preferred stock and warrants are considered to be potential common stock. The computation of diluted net loss per common share does not assume exercise or conversion of securities that would have an anti-dilutive effect. Basic net loss per common share is the amount of net income for the period available to each weighted-average share of common stock outstanding during the reporting period. Diluted net loss per common share is the amount of net loss for the period available to each weighted-average share of common stock outstanding during the reporting period and to each share of potential common stock outstanding during the period, unless inclusion of potential common stock would have an anti-dilutive effect. All outstanding options, warrants and convertible preferred stock for common shares are not included in the computation of diluted net loss per common share because they are anti-dilutive. For the three months ended March 31, 2021, and 2020, shares underlying such options, warrants, and convertible preferred stock totaled 10,187,500 and 10,946,022, respectively, and for the nine months ended March 31, 2021, and 2020, totaled 10,337,390 and 11,452,544, respectively.
