Loss Per Share

9 Months Ended

Sep. 30, 2018

Note 11. Loss Per Share

Basic and diluted loss per share is computed by dividing loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted weighted average shares outstanding for the nine months ended September 30, 2018 and 2017 excludes shares underlying stock options, warrants, convertible notes and convertible preferred because the effects would be anti-dilutive. Accordingly, basic and diluted loss per share is the same. Such excluded shares are summarized as follows:
