For purposes of calculating the ratio of earnings to fixed charges, “earnings” have been computed by adding earnings before income taxes and minority interest, amortization of capitalized interest and fixed charges, and excludes equity investee income or loss and capitalized interest. “Fixed charges” consist of interest costs, whether expensed or capitalized, and a reasonable approximation of the interest factor deemed to be included in rental expense for all facilities and equipment.
