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. Fixed charges include debt expense (interest expense and the amortization of deferred financing costs), the estimated interest component of rent expense on operating leases, and capitalized interest.
