(a) Interest expense includes amortization of debt expenses.
(b) Rent expense included in the computation consists of one-third of rental expense, which we believe to be a conservative estimate of an interest factor in our leases, which are not material.
(c) Earnings were insufficient to cover fixed charges by $670.0 million for the year ended December 31, 2008, which included a non-cash pre-tax goodwill impairment charge of $717.5 million.
