Yes. I mean, I think it's a fair point. I would highlight the following which is, when we made acquisitions, our acquisitions not necessarily had meaningfully higher EBITDA margins, right? They're reaching the 12% to 14% because of the synergies that we're bringing to bear, right? So for example, CarePoint I think was in the single-digit margins, right? And so, through our efforts in terms of the supply -- renegotiating the supply costs and the drug costs, our efforts around leveraging our corporate overhead infrastructure and through our efforts around consolidating overlapping locations, that's what's driving those margins up for InfuScience, for HomeChoice, for CarePoint. Point in fact, for example, InfuScience -- I mean, sorry, HomeChoice's EBITDA margins were kind of in the mid- to low-single digits, right? So we are generating that value by leveraging our corporate overhead. With that said, I mean, your point about our targets over the next -- and I think we gave ourselves 3 to 5 years to get there. I think that -- as a reminder, we've mentioned people that the way we believe we're going to get there, because our closest comp to that is the numbers that people see from quorum, is twofold, right? The first is that we have to get our mix up, right? And mix is a big driver of margin for us, and that's why we're so focused, Rick is focused, on the trends around core mix, right? Core mix in the fourth quarter in 2012 is about 22%, and the fourth quarter 2013 we're at about 37%. And I think as you heard Rick just answered, we're targeting -- approaching 40% by the end of 2014. So -- and then the second is scale, right. Coram is meaningfully larger than us, right? And that's the operating leverage we keep talking about. Can we continue to grow and, in fact, we keep something like our corporate overhead effectively flat? And if we can do that, then we're going to drive some very meaningful operating leverage.
