Yes, I mean, that's a good question, Brian. I mean, I think that in terms of the outlook itself, what I tried to highlight in my prepared remarks was the level of conservatism or -- even that we place in terms of the low end of range, right? And it has been a difficult year to project when we look at the trends in our non-core businesses, particularly the PBM business. Volume has clearly continued to decline. On top of that, we have the pricing impact that we had alluded to on Investor Day coming into play in the fourth quarter. So I think that -- from the PBM perspective, I think the pricing impact has been reflected in the current guidance. The volumes are always difficult to project, but we try to reflect the current trends, and we tried to reflect that at Investor Day as well, but volumes continue to decline, so we try to be more conservative on the volumes as well. So that is reflected in the low end of the guidance here. On top of that less [ph] with regards to our Infusion business, our Infusion business continues to do well from organic growth perspective. Clearly, it's less of a revenue issue, as we indicated, and it's a challenge for us on the cost side. We have highlighted here the fact that we had implemented, not that we just identified or develop, but we've actually already began implementing a cost reduction program to get at those costs, right, and to improve our margins. But in the low end of the range, all we've done is taken the September run rate number. And September -- the actual September performance for Infusion kind of back out all the onetime nonrecurring elements, multiplied that by 3 and made a modest adjustment for seasonality. We believe that is conservative, and that's our approach in terms of looking at the numbers now. And hopefully, we'll give investors confidence that we've been conservative enough. In terms of rebuilding credibility, that's a very good point. I mean, I think, for us, it is about getting the company streamlined throughout the fourth quarter and ready and prepared to go into 2014 more efficient, leaner and with good growth prospects, right? And that's all that we're looking for right now. And if we do that and we can end the year hitting these revised numbers, I think that we'll be able to be -- continue to have a more conservative approach towards guidance in 2014 that will enable us to meet or exceed expectations.
