The ratio of earnings (loss) to fixed charges is computed by dividing fixed charges into income (loss) before income taxes less equity in the income (loss) of investments plus fixed charges less the preference securities dividend requirement of consolidated subsidiaries. Fixed charges include, as applicable, interest expense, amortization of debt issuance costs, the estimated interest component of rent expense (calculated as one-third of net rent expense) and the preference securities dividend requirement of consolidated subsidiaries.
