Yes. So, Glen, that's why I made the comment because we do expect -- and there's a few reasons, one of which you stated, on why we do expect Q1 growth to really be the lowest and to accelerate throughout the year. Let me just go through the 3 or 4 reasons why we believe that. One, if you look at Q1 last year was a very strong quarter so it's a more difficult comparison. Two, we typically make a fair amount of investment spend in new hires beginning in -- at the beginning of the year for activities throughout the year so they don't start paying dividends until later in the year. Three is the point you mentioned, Glen. We think we may have cannibalized a little bit of equipment sales in Q1. Also, on equipment in Europe, as you know, the IDS show is at the end of Q1, and that typically delays equipment purchases in Europe to after the IDS show, so that will have some negative benefit in Q1 and positive benefit in Q2 and Q3. And so those are the 3 or 4 main reasons. Specifically with North American Dental equipment, we just had an outstanding quarter for equipment sales. Yes, we marketed to the tax benefits of buying this year. We do think that helped us. It's really hard to gauge how much it helped as. And again, when I look at the equipment sales growth, it was very broad-based, traditional equipment, CAD/CAM, other areas, but certainly we think we got some benefit because Section 179 was scheduled to expire so we were advising clients of that. As it turned out with a new tax law that's passed, it did not expire. In fact, the U.S. government increased Section 179 benefits to $500,000 so there may be some opportunities late in the year in 2013 to talk about that since they increased it. But clearly, we think we got some benefit because of the tax changes that we anticipated at the end of the year.
Glen J. Santangelo - Crédit Suisse AG, Research Division: Steve, maybe if I could just ask you one follow-up question. I mean, historically, we've tended to see some correlation in the direction of equipment sales and consumable sales as traffic sort of ebbs and flows through the dentist office and you kind of look this quarter and you saw your consumable numbers take another step back and we're kind of back to that growth rate in the 2009, early 2010 time frame. And I'm kind of curious to get your take, Stan, if you guys believe you're truly taking market share, what does that say about the growth rate in consumables? And are you surprised at the magnitude of the disconnect, I guess, between your equipment sales, your much stronger-than-expected equipment sales and potentially maybe slightly weaker than expected consumable numbers?
