11.  NET LOSS PER SHARE
 
Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted net loss attributable to common stockholders per share is computed by dividing net loss attributable to common stockholders, as adjusted, by the sum of the weighted average number of shares of common stock and the dilutive potential common stock equivalents then outstanding.  Potential common stock equivalents consist of stock options and warrants.  Since there is a net loss attributable to common stockholders for the years ended December 31, 2017 and 2016, the inclusion of common stock equivalents in the computation for those periods would be antidilutive. Accordingly, basic and diluted net loss per share is the same for all periods presented.
 
The following potentially dilutive securities have been excluded from the computation of diluted net loss per share since their inclusion would be antidilutive:
