Yes. Lisa, it's Rice. Let me work backwards. When you look at the private bundled contracts today, they don't include the oral drugs. We've had some discussion with some commercial payors, if you will, about the opportunity to look at this. But let's also make sure we have a similar definition on the oral drug. We would be focused on renal-specific drugs only. Our pharmacy is really based on the renal drug. It's not the full complement necessarily of drugs that a dialysis patient takes. Let's see where the government goes in '16, where we end up with this. But what I would tell you is that we've had some discussions about it with payors. But there's not much going on with that right now. I think there's just too many fish to fry at the moment but certainly, something you can come back and ask us later on. But I don't know that I can give you much more color than that today. And then on the clinic piece, obviously, should we make a decision that we were going to close a clinic, we would believe, on average, if you look around the country where we are, the vast majority of those patients we would be able to get them in one of our clinics versus having them have to go someplace else. It would be probably one of the most intense looks that we would have at if a clinic closes, how do we make sure all of these patients have a place to go, and that they're going to continue to have continuity of care in some way. So that's something we've looked at pretty intensely. But I would say to you, if you don't like my word vast majority, if you're looking for numbers, I'd say, we're thinking 65%, 70%, 75% of them, we'd be able to manage that, and we would look at that upfront going into those kind of exercises, Lisa.
Lisa Bedell Clive - Sanford C. Bernstein & Co., LLC., Research Division: Okay, that's really helpful. And then last question on Fresenius Rx, just thinking about the number of patients you have in that program right now, I guess, what was it, you said 40,000 or 50,000 today. Are those mainly private patients? I'm just trying to understand, out of the 170,000 patients you treat in North America, how penetrated you are? And how -- and could you get to peak penetration? I mean, what is peak penetration? Could you actually provide Fresenius Rx services to all those patients over time?
