(Loss) Earnings per Common Share
Basic earnings per share is calculated using the weighted average number of shares outstanding for the period. Diluted earnings per share is computed on the basis of the weighted average basic shares outstanding plus the dilutive effect of our stock-based compensation plans using the “treasury stock” method. Unvested restricted stock and treasury shares are excluded from the calculation of weighted average number of common stock outstanding because they do not participate in dividends. Once restricted stock vests, it is included in our common stock outstanding.
The following table sets forth the computation of the weighted average basic and diluted income (loss) per share:
