Exhibit 12.1

Calculation of Ratios of Earnings of Fixed Charges

The following table sets forth, for each of the periods presented, the historical ratio of earnings to fixed charges. The historical ratios are prepared on a consolidated basis.

The ratio of earnings to fixed charges for each of the periods presented is determined by dividing earnings by fixed charges. Earnings consist of income (loss) from operations before income taxes and fixed charges. Fixed charges consist of interest incurred, amortization of debt discount and debt issuance costs, and an estimate of the interest portion of rent expense.
