Basic and Diluted Earnings (Loss) per Share

Basic earnings (loss) per common share is computed using the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per common share is computed using the weighted average number of common shares and potential dilutive common shares that were outstanding during the period. Potential dilutive common shares consist of outstanding stock options, outstanding stock warrants, and convertible preferred stock.

The following table sets forth the computation of basic and diluted earnings (loss) per share:
