Earnings Per Share [Abstract]
Loss per Share	Loss per Share Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed using the weighted average number of common shares plus potentially dilutive common shares. Potentially dilutive common shares include employee stock options and restricted share units and warrants and debt that are convertible into the Company’s common stock. Because the Company incurred net losses in the three and nine months ended September 30, 2017 and 2016, the effect of potentially dilutive securities has been excluded in the computation of diluted loss per share as their impact would be anti-dilutive. Potentially dilutive common stock equivalents excluded were 2.0 million shares during the three and nine months ended September 30, 2017. Potentially dilutive common stock equivalents excluded were 4.8 million and 4.3 million shares during the three and nine months ended September 30, 2016, respectively.

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed using the weighted average number of common shares plus potentially dilutive common shares. Potentially dilutive common shares include employee stock options and restricted share units and warrants and debt that are convertible into the Company’s common stock.

Because the Company incurred net losses in the three and nine months ended September 30, 2017 and 2016, the effect of potentially dilutive securities has been excluded in the computation of diluted loss per share as their impact would be anti-dilutive. Potentially dilutive common stock equivalents excluded were 2.0 million shares during the three and nine months ended September 30, 2017. Potentially dilutive common stock equivalents excluded were 4.8 million and 4.3 million shares during the three and nine months ended September 30, 2016, respectively.
