Earnings Per Share, Basic and Diluted [Abstract]

Earnings Per Share [Text Block]

Net Income (Loss) per Share

Basic net income (loss) per share is computed using the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is calculated using the weighted average number of shares of common stock plus, when dilutive, potential shares of common stock outstanding using the treasury-stock method. Potential shares of common stock outstanding include stock options, unvested restricted stock awards and restricted stock units, and warrants.

The components of basic and diluted earnings per share were as follows (in thousands, except share and per share information):
