* Earnings (loss) per share is computed independently for earnings (loss) per share from continuing operations and earnings (loss) per share from discontinued operations. The sum of earnings (loss) per share from continuing operations and earnings (loss) per share from discontinued operations does not equal earnings (loss) per share due to rounding.
