Segment Information
We operate in two business segments—human pharmaceutical products and animal health. Our business
segments are distinguished by the ultimate end user of the product—humans or animals. Performance is
evaluated based on profit or loss from operations before income taxes. The accounting policies of the
individual segments are the same as those described in the summary of significant accounting policies in
Note 1 to the consolidated financial statements.
Our human pharmaceutical products segment includes the discovery, development, manufacturing,
marketing, and sales of human pharmaceutical products worldwide in the following therapeutic areas:
neuroscience, endocrinology, oncology, cardiovascular, and other. Our neuroscience group of products
includes Cymbalta, Zyprexa, Strattera, and Prozac. Endocrinology products consist primarily of Humalog,
Humulin, Forteo, Evista, Humatrope, Byetta, and Actos. Oncology products consist primarily of Alimta, Erbitux,
and Gemzar. Cardiovascular products consist primarily of Cialis, Effient, and ReoPro. The other
pharmaceuticals category includes anti-infectives, primarily Vancocin and Ceclor, and other miscellaneous
pharmaceutical products and services.
Our animal health segment, operating through our Elanco animal health division, includes the development,
manufacturing, marketing, and sales of animal health products worldwide for both food and companion
animals. Animal health products include Rumensin, Tylan, Posilac, Paylean, and other products for livestock
and poultry, as well as Trifexis, Comfortis, and other products for companion animals.
Most of our pharmaceutical products are distributed through wholesalers that serve pharmacies, physicians
and other health care professionals, and hospitals. For the years ended December 31, 2012, 2011, and 2010,
our three largest wholesalers each accounted for between 10 percent and 16 percent of consolidated total
revenue. Further, they each accounted for between 9 percent and 14 percent of accounts receivable as of
December 31, 2012 and 2011. Animal health products are sold primarily to wholesale distributors.
We manage our assets on a total company basis, not by operating segment, as the assets of the animal health
business are intermixed with those of the pharmaceutical products business. Therefore, our chief operating
decision maker does not review any asset information by operating segment and, accordingly, we do not
report asset information by operating segment.
We are exposed to the risk of changes in social, political, and economic conditions inherent in foreign
operations, and our results of operations and the value of our foreign assets are affected by fluctuations in
foreign currency exchange rates.
