(1) Includes amortization of premiums, discounts, and capitalized debt expense and interest component of rent expense.

For the purpose of calculating the ratios of earnings to fixed charges, “Fixed charges” represent the aggregate of interest charges on short-term and long-term debt (whether expensed or capitalized), the portion of rental expense deemed to be attributable to interest, and the pre-tax preferred stock dividend requirement of SPPC.  “Earnings” represents pre-tax income from continuing operations before, solely with respect to the years ended December 31, 2006 and 2005, pre-tax preferred stock dividend requirement of SPPC plus fixed charges (excluding capitalized interest and the pre-tax preferred stock dividend requirement of SPPC for the years ended December 31, 2006 and 2005).
