| Net Loss per Common Share |
4. Net Loss per Common Share Basic net loss per share was determined by dividing net loss by the weighted average common shares outstanding during the period. Diluted net loss per share was determined by dividing net loss by diluted weighted average shares outstanding. Diluted weighted average shares reflect the dilutive effect, if any, of common stock options based on the treasury stock method. For all financial statement periods presented the number of basic and diluted weighted average shares outstanding was the same because any increase in the number of shares of common stock equivalents for any period presented would be antidilutive based on the net loss for the period. For the six months ended June 30, 2016 and 2015, approximately 5.9 million and 0.9 million weighted average shares subject to stock options and warrants, respectively, as calculated using the treasury stock method, were excluded from the calculation of diluted weighted average common shares outstanding as their effect would have been antidilutive. |
