For purposes of calculating our ratio of earnings to fixed charges, earnings consist of earnings from continuing operations before income taxes, extraordinary items and before adjustment for noncontrolling interests, adjusted for the portion of fixed charges deducted from the earnings, plus amortization of capitalized interest. Fixed charges consist of interest on all indebtedness, including capitalized interest, and amortization of debt issuances costs.
