RATIO OF EARNINGS TO FIXED CHARGES

The ratio of earnings to fixed charges is computed by dividing earnings by fixed charges. Earnings for this purpose are defined as pretax income from continuing operations adjusted by adding back fixed charges expensed during the period less pre-tax net income attributable to noncontrolling interests. Fixed charges include debt expense (interest expense, the amortization of deferred financing costs and the amortization of the cap premium), the estimated interest component of rent expense on operating leases, and capitalized interest.
