Exhibit 12.1

RATIO OF EARNINGS TO FIXED CHARGES 

The following table sets forth our ratio of earnings to fixed charges on a reported basis for the periods indicated. Earnings consist of income from continuing operations plus fixed charges. Fixed charges consist of interest expense, amortization of deferred financing costs and costs related to retiring certain debt early. We have calculated the ratio of earnings to fixed charges by adding net income from continuing operations to fixed charges and dividing that sum by such fixed charges.
