Loss Per Share	Loss Per Share Basic loss per share equals net loss divided by the weighted average common shares outstanding during the period. Diluted loss per share equals net loss divided by the sum of the weighted average common shares outstanding during the period plus dilutive common stock equivalents. The calculation of loss per common share on a basic and diluted basis was the same for the three and nine month periods ended September 30, 2017 and 2016, because the inclusion of dilutive common stock equivalents - the A&R Warrant (1,317,289 shares), the 10% Warrant (326,052 shares), the 2017 Private Offering Warrants (2,187,500 shares), and the August Warrant (450,000 shares) (all as defined in Note 8 to the condensed consolidated financial statements), would have been anti-dilutive for all periods presented. The Company has granted options to purchase shares of the Company's common stock through employee stock plans with the weighted average options outstanding as of September 30, 2017 and 2016, of 1,335,511 and 356,288, respectively, all of which were outstanding as of September 30, 2017, but are anti-dilutive because the Company is in a net loss position.

Loss Per Share

Basic loss per share equals net loss divided by the weighted average common shares outstanding during the period. Diluted loss per share equals net loss divided by the sum of the weighted average common shares outstanding during the period plus dilutive common stock equivalents. The calculation of loss per common share on a basic and diluted basis was the same for the three and nine month periods ended September 30, 2017 and 2016, because the inclusion of dilutive common stock equivalents - the A&R Warrant (1,317,289 shares), the 10% Warrant (326,052 shares), the 2017 Private Offering Warrants (2,187,500 shares), and the August Warrant (450,000 shares) (all as defined in Note 8 to the condensed consolidated financial statements), would have been anti-dilutive for all periods presented. The Company has granted options to purchase shares of the Company's common stock through employee stock plans with the weighted average options outstanding as of September 30, 2017 and 2016, of 1,335,511 and 356,288, respectively, all of which were outstanding as of September 30, 2017, but are anti-dilutive because the Company is in a net loss position.
