For the purpose of computing the ratio of earnings to fixed charges, earnings consist of income before provision for income taxes and before adjustment for losses or earnings from equity investments plus fixed charges and dividends received from equity investments. Fixed charges consist of interest charges (whether expensed or capitalized), amortization of debt expense and that portion of rental expense we believe to be representative of interest. Note that prior to our fiscal year ended March 31, 2006, interest charges and that portion of rental expense representative of interest were immaterial.

As of the date of this registration statement, we have not issued any shares of preferred stock.
