(1) The ratio of earnings to fixed charges is computed by dividing the sum of pre-tax income from continuing operations (before adjustment for minority interests in consolidated subsidiaries and loss from equity investees) plus fixed charges, by fixed charges. Fixed charges consist of interest charges, whether expensed or capitalized, and that portion of rental expense we believe to be representative of interest.
