(1)                                For purposes of determining the ratio of earnings to fixed charges, earnings are defined as income from continuing operations before income taxes and non-controlling interest, plus fixed charges and amortization of capitalized interest, less capitalized interest. Fixed charges consist of interest incurred (whether expensed or capitalized), amortization of deferred financing costs and an estimate of the interest within rental expense.  All reported periods of the calculation of the ratio of earnings to fixed charges exclude discontinued operations.
