10. Earnings Per Share

Basic earnings per share is computed on the basis of weighted average outstanding common shares. Diluted earnings 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):

The diluted earnings (loss) per share computation excludes 1.4 million and 5.9 million options to purchase shares, restricted share awards, common stock warrants and contingently issuable shares during the three and nine months ended September 30, 2012, respectively, as their effect would be anti-dilutive. The diluted earnings per share computation for the three and nine months ended September 30, 2011, excludes 3.2 million options to purchase shares, restricted share awards, common stock warrants and contingently issuable shares as their effect would be anti-dilutive.
