     For purposes of computing the ratios of earnings to fixed charges, earnings consist of pre-tax income from continuing operations before equity in (earnings) loss from unconsolidated affiliates plus fixed charges, amortization of capitalized interest and distributions from equity investees less capitalized interest and preference equity distributions. Fixed charges consist of interest expensed and capitalized, distributions on preference units and the estimated interest component of rent expense. Earnings were inadequate to cover fixed charges for the years ended December 31, 2004 by $1.3 million.
