(1) For the purpose of computing the ratio of earnings to fixed charges,
earnings consist of pre-tax income (loss) from continuing operations,
excluding minority interests in gains/losses of consolidated subsidiaries,
and fixed charges consist of pre-tax interest (including capitalized
interest) on all indebtedness, amortization of debt discount and expense,
and that portion of rental expense that we believe to be representative of
interest.
