(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, “Earnings” represents net income (or loss) adjusted for income taxes (benefits) and fixed charges excluding capitalized interest.  “Fixed charges” represent the aggregate of interest charges on long-term debt (whether expensed or capitalized) and the portion of rental expense deemed attributable to interest.
