⁽¹⁾		The ratio of earnings to fixed charges is computed by dividing loss before taxes plus fixed charges by fixed charges. Fixed charges consist of interest expense (including interest expense from capital leases) and the estimated portion of rental expense deemed by the Company to be representative of the interest factor of rental payments under operating leases. Earnings were insufficient to cover fixed charges by the amounts sent forth in the table above under the heading “Deficiency in the coverage of fixed charges.”
