VIDEO TRANSCRIPT

Vincent A. Forlenza: BD is doing this transaction to bring together two great companies to improve a very important process in the hospital – that’s medication management. It’s an area of big concern for hospitals. Both companies have complementary products that can be brought together to simplify this process and improve it. This is a perfect fit. It’s a perfect fit for BD, it’s a perfect fit for our customers.

The second reason is these companies are a perfect fit from a geographical standpoint. BD has invested in a global infrastructure, CareFusion has been very U.S. focused and trying to build out that infrastructure, but this accelerates that strategy for both of the companies. So all of these elements together are very exciting.

Kieran T. Gallahue: It’s a great example of taking two very aligned organizations from a cultural perspective, but that have complementary strengths. Whether it’s a geographic perspective or whether it’s from a product perspective – and we fit together like really truly wonderful pieces of a puzzle.

You know our, at CareFusion our focus has been on lowering the cost of care while improving patient safety, and doing so in a way to try to touch patients around the globe. This helps accelerate that vision.

VF: Together, we can improve healthcare both in medication management and in procedural solutions. Both of those opportunities are exciting for BD and CareFusion and within the global context.

Both companies have tremendous clinical knowledge, and we can bring that knowledge to bear around the globe – whether it’s in China or Brazil, in Europe or in the US, and when you bring that knowledge together we’re going to improve healthcare. We believe we can do that together and we can do it better together.

KG: You know, hospitals around the globe, healthcare systems around the globe, are struggling with the reality that they need to do more with less. They need to be able to manage a demographic which suggests aging populations, more on developing economies, be able to reach more patients that, to date, have not been able to have access to quality care.

VF: BD is a stronger company today, with more opportunity for people across the entire company. We remain focused and committed to our businesses on the diagnostic and bioscience side of the business. We have major R&D programs that will continue to move ahead. We see great opportunity within those businesses to grow and we are going to drive those strategies.

So my vision for BD is a more innovative, more global, more impactful company, and today we get up and we have more capability to fulfill that vision than we had yesterday – in fact, tremendously more capability. So as I look to the future, I see a company that has the ability to impact problems in healthcare around the globe with a scale that we did not have before – to help all people live healthy lives and do it faster and more impactful.
