Biopharmaceutical Revenues

Biopharmaceutical revenues contributed approximately 86% of our total revenues in 2010 and 91% of our total revenues in 2009 and 2008.

These products represented 60% of our Biopharmaceutical revenues in 2010, 56% of our Biopharmaceutical revenues in 2009 and 60% of our Biopharmaceutical revenues in 2008. We did not record more than $1 billion in revenues for any individual legacy Wyeth product in 2009 as the Wyeth acquisition date was October 15, 2009. While Wyeth’s revenues are not included in our 2008 amounts, as Wyeth had not yet been acquired, Wyeth had five products with direct product revenues of more than $1 billion in 2008.
