Net Income (Loss) Per Share [Abstract]

Earnings Per Share [Text Block]

Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding, while diluted net income (loss) per share is computed by dividing net income (loss) attributable to common shareholders by the sum of the weighted average number of common shares outstanding and all dilutive potential common shares outstanding. Dilutive potential common shares relate to our stock-based compensation arrangements and our outstanding convertible senior notes. For all calculations, the determination of whether potential common shares are dilutive or anti-dilutive is based on net income (loss) from continuing operations.

The calculation of the basic and diluted net income (loss) per share was as follows:
