(B) “Fixed charges” are defined as interest on borrowings (whether expensed or capitalized), the portion of rental expense applicable to interest, and amortization of debt issuance costs.

(C) Due to the company’s pre-tax loss, the ratio of earnings to fixed charges was less than 1:1 for the six months ended March 31, 2005. Additional earnings of $41 million would have been required to make the ratio 1:1.
