EarningsPerShareTextBlock | Loss Per Common Share. Basic loss per common share (“Basic EPS”) is computed by dividing net loss available to common stock holders (the “numerator”) by the weighted average number of common shares outstanding (the “denominator”) during the period. Diluted loss per common share (“Diluted EPS”) is similar to the computation of Basic EPS 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 had been issued. In addition, in computing the dilutive effect of convertible securities, the numerator is adjusted to add back the after-tax amount of interest recognized in the period associated with any convertible debt. The computation of Diluted EPS does not assume exercise or conversion of securities that would have an anti-dilutive effect on net earnings per share. The following is a reconciliation of the denominator of the basic loss per common share computation to the denominator of the diluted loss per common share computations, for the years ended December 3 1 |
