(1) For purposes of determining the ratio of earnings to fixed charges, earnings include income from continuing operations before income taxes adjusted for fixed charges and equity in earnings of unconsolidated subsidiaries and related distributions. Fixed charges consist of interest on debt, including amortization of debt issuance costs, and one-fourth of rent expenses, which we estimate as the interest component of such rentals.
