(1) The ratio of earnings to fixed charges was calculated by dividing (i) net income (loss) before income taxes and fixed charges by (ii) fixed charges which consist of interest expense incurred, including amortization of debt expense and discount, and one-third of rental expense, which approximates the interest portion of our rental expense. For the years ended December 31, 2000 and 2002, our earnings were not sufficient to cover our fixed charges by $58.9 million and $20.0 million, respectively.
