Exhibit 12.1

STATEMENT REGARDING COMPUTATION OF RATIO OF EARNINGS TO FIXED CHARGES AND PREFERENCE DIVIDENDS

The following illustrates the computation of the historical ratio of earnings to fixed charges (amounts in thousands except ratios). There were either no preference securities outstanding for each of the following periods, or in the case of the period ended December 31, 2009, no preference dividends accrued or payable on preference securities outstanding. Therefore, the ratio of earnings to combined fixed charges and preference dividends are identical to the ratios of earnings to fixed charges.
