Sure. And Chris, so I'm going to steal a little bit of these from a couple of analyst reports I wrote, although I'm not saying this is the whole thing. So clearly, Q1 was a light quarter for us in the Americas. There's no question about that. I think it was 19% international and 4% Americas was the growth rate. One thing we did see and you remember the guidance in -- I'm going to go back to Q4 for a second here, but we guided 16.5% in Q4 midway through and then we came in with this crazy number of 17.9%, I believe. So we're 1.4% ahead of our guidance in Q4. It feels to me in retrospect now having had a chance to watch these 2 quarters next to each other, that we got a lot of sales and this holds true for the Americas as well as outside of the U.S., but I think the function was stronger in the Americas. We got a lot of sales that we didn't expect in Q4. Again, 1.4% beyond our guidance. And then we missed our guidance by $300,000 in Q1, feels to me like a lot of the sales were stolen from Q1 into Q4, we didn't know this at that time. There were a couple of contests running inside our company, but actually, I think, at a higher level and we've seen this in a couple of analyst reports, people believe that because ObamaCare was really [indiscernible] in January of 2014, that a lot of folks out there, a lot of patients out there, drove their procedures to happen in November and December so they didn't have to worry about what would happen in the new world of ObamaCare, where potentially, they wouldn't be able to visit their own doctors or their own hospitals. So we think we saw some of that, although, I hate to throw everything at external forces. And clearly, there's some issues at our company we need to work a lot harder. In the Americas, I'm excited to see going forward a lot more training. We haven't grown our salesforce in the U.S. for a while. So we need to get back on the horse on that. But I think those 2 things, as well as the GPO that we just signed with Premier, which started April 1, should encourage a little bit more American growth. So again, a couple of things. I feel like the ObamaCare thing did actually do something good for us in Q4 and maybe that took it out of Q1 and then secondarily, there are some things we need to work on.
