Basic and Diluted Net Loss per Share

Basic and Diluted Net Loss per Share

Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per common share is computed giving effect to all dilutive potential common shares that were outstanding during the period. Diluted potential common shares consist of incremental shares issuable upon exercise of stock options, restricted stock units, warrants and preferred stock.

For the three month period ended March 31, 2020, the effect of the beneficial conversion charge related to the Series A preferred stock is included in the calculation of net loss attributable to common stockholders. No adjustments have been made to the weighted average outstanding common shares figures for the three month periods ended March 31, 2020 or March 31, 2019 as the assumed conversion of preferred stock and exercise of outstanding options, warrants and restricted stock units would be anti-dilutive.

As of March 31, 2020, there were 4,884,117 outstanding shares of preferred stock, 1,741,022 outstanding options, 51,373,394 outstanding warrants, and 285,595 unvested restricted stock units that were excluded from the calculation of diluted net loss per common share as the effect of including these instruments would have been anti-dilutive.
