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 months ended March 31, 2015, the weighted average number of stock options and restricted stock units excluded from the computation of diluted earnings per share were 299 and 0, respectively. For the three months ended March 31, 2014, all outstanding stock options and restricted stock units totaling 739 and 1,377, respectively, were excluded from the computation of diluted loss per share because the effect in the periods would be anti-dilutive. 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 anti-dilutive.
The Company’s basic and diluted earnings (loss) per share amounts are as follows:
