Earnings (Loss) Per Share [Abstract]  
Earnings Per Share [Text Block]
Earnings (Loss) Per Share
Basic earnings (loss) per share is calculated using the weighted average number of shares of common stock outstanding during the period.  Diluted earnings per share is computed in the same manner and also gives effect to all dilutive common equivalent shares outstanding during the period.  Potential common shares that would have the effect of increasing diluted earnings per share are considered to be antidilutive. In accordance with U.S. GAAP, these shares were not included in calculating diluted earnings per share. For the three and nine months ended September 30, 2014, all outstanding restricted stock units of 1,247 and stock options of 654 were excluded from the computation of diluted loss per share because the effect in the period would be antidilutive. For the three and nine months ended September 30, 2013, the weighted average number of stock options and restricted stock units excluded from the computation of diluted earnings per share totaled 672 and 731, respectively, because their effect was antidilutive. Diluted earnings per share-weighted average shares outstanding do not include any effect resulting from assumed conversion of the Notes and warrants as their impact would be antidilutive.
The Company’s basic and diluted earnings (loss) per share amounts are as follows:
