(1) Interest expense includes amortization of deferred financing costs. Interest expense also includes an amount related to our capital lease with TV Azteca.

(2) For the purposes of this calculation, “earnings” consists of income from continuing operations before income taxes, income on equity method investments, fixed charges (excluding interest capitalized and amortization of interest capitalized). “Fixed charges” consists of interest expensed and capitalized, amortization of debt discounts and premiums and related issuance costs and the component of rental expense associated with operating leases believed by management to be representative of the interest factor thereon.
