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.

The following table lists the weighted average number of stock options and restricted stock units excluded from computation of diluted earnings per share at December 31, 2012 and 2013 as there impact would be anti-dilutive:

	Year Ended December 31,
	2012	2013
Stock options	984	707
Restricted stock units	37	3

For the year ended December 31, 2014, all outstanding restricted stock units of 805 and stock options of 615 were excluded from the computation of diluted loss per shares because the effect in the period would be antidilutive.

Diluted earnings per share-weighted average shares outstanding do not include any effect resulting from assumed conversion of the Notes and warrants (as described in Note 8) as their impact would be anti-dilutive.

The computations of basic and diluted income per share for the years ended December 31, 2012, 2013, and 2014 are as follows:
