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 millions except ratios). We have one share of Series A Voting Preferred Stock outstanding, which does not entitle the holder to have any dividend rights. As a result, the ratio of earnings to combined fixed charges and preference dividends are identical to the ratios of earnings to fixed charges.
