The term “fixed charge” means the sum of the following: interest expensed and capitalized, amortized premiums, discounts and capitalized expenses related to indebtedness; and an estimate of interest within rental expense (equal to one-third of rental expense). Management believes this is a reasonable approximation of the interest factor.

Where a dash appears, our earnings were negative and were insufficient to cover fixed charges during the period. Our deficiencies to cover fixed charges in each period presented were as follows:
