From Diversity Comes Strength

As a multi-specialty health care company, one of Allergan’s unique strengths is our diversity of product lines that include specialty pharmaceuticals, biologics, medical devices and over-the-counter consumer products. But we are not diverse for diversity’s sake. Rather, we are rigorous in deciding which markets to invest in and grow based on our organic R&D, our track record of leadership, and our assessment of unmet medical needs and consumer wants. At the same time, we recognize there are clear benefits to our multi-specialty focus, especially in today’s challenging health care environment.

For instance, approximately one-third of our revenues are derived from medical aesthetics and health products that are electively paid for out-of-pocket by the patient or consumer. In our experience, these expenditures have shown minimal response to shifts in economic cycles because demand has existed across a wide swath of income levels and demographics. Perhaps more significantly, however, this product mix diversifies our risk by providing some protection from increasingly restrictive pricing and reimbursement practices in the United States, Europe and other leading global markets.

In this environment, we are committed to ensuring patients have access to the best medical therapies they need and deserve. We are proud of our investment and effort in reimbursement and of our results. We have high medical coverage for many of our therapeutic products by Medicare Part D and with other payors in the United States, as well as in national formularies, thanks to our strong market positions in therapeutic areas such as ophthalmology and neurosciences.
