Common stock equivalents, which are anti-dilutive, are excluded from the computation of diluted net income (loss) per share. (2) The ratio of earnings to fixed charges is computed by dividing fixed charges into earnings. Earnings is defined as pretax income from continuing operations adjusted by adding fixed charges and excluding interest capitalized during the period. Fixed charges means the total of interest expense and amortization of financing costs, the estimated interest component of rental expense on operating leases and preferred stock dividends. If the ratio of earnings to fixed charges is less than one-to-one, then the amount of the deficiency is presented. (3) Book value per share is computed using the number of outstanding shares of common stock at the end of each respective period. Book value per share does not include the effect of options or other common stock equivalents outstanding during the period.
