No. So the -- again, so the 20 basis points at current revenue growth rates, we think is doable. That's what our plan is calling for, for 2014. The interesting thing is that, yes, while it was for the quarter, it was down a little bit 5 basis points. And that -- and, Glen, that 5 excludes acquisition impact. But on a full year basis, it was actually up slightly, excluding acquisitions. It wasn't quite the 20 basis points. It was high single basis points. It was 7 or 8 basis points improvement for the full year. One thing I'll point out that impacted Q4 is if you look at all the acquisition activity that we announced in early Q1, a lot of expenses set in Q4 to drive that acquisition expense -- to drive those acquisition activities in Q1. So we record the diligence cost, the professional fees, all of those acquisition, of course, as incurred. So they're always incurred prior to the acquisition being completed. So we're a little bit heavy in Q4 on those expenses because we did have a lot of activity that was announced in early Q1. The interesting thing also is that when you look at Q4, there was a lot of mix impact because when I look at the individual businesses, Dental, Medical, Animal Health and Technology, and this may sound like a contradiction but it's not. Each of them had margin expansion in Q4, each of them. And yet because of mix, it was down 5 basis points. So I guess the short answer to conclude is that we do believe that we can get operating margin expansion in 2014, and that's what our internal plans call for.
Glen J. Santangelo - Crédit Suisse AG, Research Division: And Steve, maybe if I can just ask a follow-up question on some of these recent acquisitions. It seems like you obviously trimmed your fiscal '14 guidance a little bit a few weeks ago when you announced these deals. And I'm kind of curious, I mean, what's driving that near-term dilution? Is it mostly the amortization related to these acquisitions? If we were to look at it x the amortization, would these deals be accretive in year 1 or is there something -- is there a new trend with respect to -- we seen any inflation in the purchase prices for these assets. Can you just give us a little bit more color? It would be helpful.
