Earnings (Loss) Per Share

8. Earnings (Loss) Per Share

Earnings (loss) per share is computed in accordance with U.S. GAAP. Basic earnings (loss) per share is computed on the basis of weighted average outstanding common shares. Diluted earnings (loss) per share is computed on the basis of basic weighted average outstanding common shares adjusted for the dilutive effect of stock options and other outstanding dilutive securities.

The following table reconciles the average share amounts used to compute both basic and diluted loss per share (in thousands):

Diluted weighted average shares outstanding		34,254		33,500		34,120		33,612

For the three and six months ended June 30, 2010, 6.7 million options to purchase shares, restricted share awards, common stock warrants and contingently issuable shares were excluded from the diluted earnings per share computation as their effect would be anti-dilutive.
