3. Earnings (Loss) Per Share

Earnings (loss) per common share is computed based on the weighted-average number of common shares outstanding and, when appropriate, dilutive potential common stock outstanding during the period. Stock options are considered to be potential common stock. The computation of diluted earnings (loss) per share does not assume exercise or conversion of securities that would have an anti-dilutive effect.

Basic earnings (loss) per common share is the amount of net earnings (loss) for the period available to each weighted-average share of common stock outstanding during the reporting period. Diluted earnings (loss) per common share is the amount of earnings (loss) for the period available to each weighted-average share of common stock outstanding during the reporting period and to each share of potential common stock outstanding during the period, unless inclusion of potential common stock would have an anti-dilutive effect.

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