Sure, Lisa. Clearly, we have to continue to evolve our model as our customers aggregate together perhaps in larger practices, or as you said, some of them have chosen to sell their practices to hospitals or to IDNs. What's great about McKesson is we have a very, I think, a strong relationship and an understanding for the acute side of the business. As you may recall, we had an acute Med-Surg business at one point, which we sold. But our knowledge of that marketplace, in how hospitals operate and hospital GPOs operate, I think, has benefited us as we've evolved our model to provide service and solutions to customers who either are existing customers who are being acquired and want to remain with McKesson or -- and frankly, new customers that have been acquired by hospitals, where hospitals are struggling with a more unified approach to their supply chain requirements. Clearly, the acute care distributors stand in a position to compete with us for that business, but because they have a position in the hospital space. But we also think there's an opportunity for us to continue to service these customers, and we have had very little customer attrition through an acquisition by a health system or a hospital. And I think the priority for those health systems, frankly, is not the 1% or 2% of the supply chain cost that those physicians may represent of their entire medical-surgical spend, I think they're more focused on the productivity and efficiency and alignment those physicians might have with the enterprise, particularly if they're trying to build a at-risk ACO or PCMH kind of a model. And so I think that to the extent that they can put the logistics and supply chain requirements behind them and not have to disrupt that productivity by making significant changes in distribution, they benefit. So we have successfully navigated with our customers these changes in their ownership models, and I think we're well positioned to handle the scale requirements that are necessary for hospital customers. Having said that, clearly, we have competitors on the acute care side that have an avenue into this marketplace, and we have to be vigilant on our value proposition.
Lisa C. Gill - JP Morgan Chase & Co, Research Division: And then just as a follow-up, John, for you or Jeff. How do we think about the synergies that you talked about, the $100 million, is that just cost? Or do you think that there's some level of revenue synergies, especially from an IT perspective? My understanding is that today, Athena has a relationship with PSS. So do you see that as a future revenue relationship opportunity?
