Yes. I mean, I think that what we try to highlight in the outlook section, I think, kind of gets right at that question, Brooks. I mean, I think that clearly, we benefit from the acquisition here, right? We've got the full year of InfuScience that's coming in. We'll have some contribution, obviously, from the HomeChoice acquisition on top of the recovery from Sandy and then the organic growth on top of that, right? So -- but in terms of the risk and the opportunities, I think therapy mix is always going to have an impact, right? And both could be positive, right, as well as negative from margin percentage prospective. I don't think it's negative in terms our ability to create operating leverage, so long as we can still grow the dollars, right, at the gross profit line. The lingering effects of Sandy, we've talked about. We believe that, that's primarily the first quarter but we'll have a better assessment as we move along here. And then the other opportunities, right, for us are things like additional acquisitions that may impact the number, de novos, right, that might -- if we decide to move beyond the 8 that we've got kind of in our pipeline right now, that would be a bit of a drag for us, or -- but that could be offset by better performance from the 8 that we're bringing online, right? And then the integration of HomeChoice is also a variable for us, right, to the extent that we do better than, I think, what I guided to, which was on the last call, 9 to 12 months to fully integrate, then I think, that we'll clearly have some upside there.
Brooks G. O'Neil - Dougherty & Company LLC, Research Division: That's great. And then just one last question. I'm curious, I think you mentioned in the press release the impact of competitive bidding and you might have also mentioned it here. Could you just highlight what's going on with competitive bidding and how it might impact the company in 2013?
