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 no preference securities outstanding for the following periods. Therefore, the ratio of earnings to combined fixed charges and preference dividends are identical to the ratios of earnings to fixed charges.
