Basic (loss) earnings per common share amounts are calculated by dividing income available to common shareholders, after deducting preferred stock dividends, by the weighted average number of shares of common stock outstanding. Diluted (loss) earnings per common share amounts are calculated by dividing net income by the weighted average number of shares of common stock outstanding adjusted to give effect to potentially dilutive securities.

Diluted (loss) earnings per share includes the potential dilutive effect of common stock equivalents as if such securities were converted or exercised during the period when the effect is dilutive. Because the impact of these items is generally anti-dilutive during periods of net loss, there is no difference between basic and diluted loss per common share for periods with net losses.

Weighted average common share equivalents that have an anti-dilutive impact are excluded from the computation of diluted (loss) earnings per common share.
