All financial information reflects the following as discontinued operations for 2006, 2005 and 2004: the Consumer Healthcare business; certain European generics businesses; and for 2004: our in-vitro allergy and autoimmune diagnostics testing, and surgical ophthalmics.

^(a) Interest expense includes amortization of debt premium, discount and expenses. Interest expense does not include interest related to uncertain tax positions of $333 million for 2008; $331 million for 2007; $200 million for 2006; $203 million for 2005; and $201 million for 2004.

^(b) Preferred stock dividends are from our Series A convertible perpetual preferred stock held by an Employee Stock Ownership Plan assumed in connection with our acquisition of Pharmacia in 2003.

^(c) Rents included in the computation consist 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.
