The ratio of earnings to fixed charges is computed by dividing income or loss before taxes plus fixed charges by fixed charges. Fixed
charges consist of interest expense and the estimated portion of rental expense deemed by us to be representative of the interest factor of rental payments under operating leases. The dollar amount of deficiency in earnings available for fixed
charges for a one-to-one ratio for 2005 was $14,840.
