Exhibit 12.1

STATEMENT REGARDING COMPUTATION OF RATIO OF EARNINGS TO FIXED CHARGES

The following illustrates the computation of the historical ratio of earnings to fixed charges (amounts in thousands except ratios). While there are preference securities outstanding for all periods presented, such preference securities do not accrue or otherwise pay any dividends. Therefore, the ratio of earnings to combined fixed charges and preference dividends are identical to the ratios of earnings to fixed charges.

* Interest component of rental expense is estimated to equal 1/3 of such expense, which is considered a reasonable approximation of the interest factor.
