(2) Other fixed charges represent mainly the estimated interest component within rental expense.
For the purposes of calculating our ratio of earnings to fixed charges, earnings consist of income from continuing operations before taxes, to which we add back fixed charges and exclude income or loss from equity-accounted companies. Fixed charges consist of interest expense, the amortization of premiums, discounts and capitalized expenses related to indebtedness, and the portion of rental expense deemed representative of an interest factor. Interest expense excludes tax-related interest expense.
