Basic earnings (loss) per share is computed by dividing net income or loss by the weighted-average number of common shares outstanding. Diluted earnings (loss) per share is computed similar to basic earnings (loss) per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the dilutive potential common shares from share-based compensation arrangements had been issued.

Potentially dilutive shares arise from non-qualified stock options to purchase common stock and non-vested restricted stock. The treasury stock method is applied to determine the number of potentially dilutive shares for non-vested restricted stock and stock options assuming that the shares of non-vested restricted stock are issued for an amount based on the grant date market price of the shares and that the outstanding stock options are exercised. These amounts were excluded because the effect would be anti-dilutive.
