    (LOSS) INCOME PER COMMON AND COMMON STOCK EQUIVALENT SHARE
 
Basic (loss) income per share is computed based on the weighted-average number of common shares outstanding.  Diluted income per common share is calculated assuming the exercise of stock options except where the result would be anti-dilutive.  The following table reconciles the numerator and denominator used to calculate basic and diluted income per share:
