Sure. I'll be happy to. First of all, we think -- Mark and I believe, along with the board, that our job in these earnings call is to not be cheerleaders for the company, as much as try to express the risks that we see potentially out there. But sometimes we may overemphasize things that are not as bad as they seem. But at the time, we think, "Okay, in hindsight, could we be viewed that we're not sharing as much as we could with our shareholders about the negative?" So last time, we did spend some time talking about the competitive environment. But obviously, that's always there. There's always price pressure there as you compete for market share, which is what we've been in competition for the last several years, close to GPOs opening up to Masimo in the U.S. But I can tell you that things are working fine. We're doing things that are going to reduce our costs, hopefully, more than the competition is going to reduce our ASP. So -- and if I just look at Q2, I can tell you, looking back at Q2, we felt that while prices have adjusted since several years ago when we first got on GPO contracts, it didn't feel like Q2, there was any more downward pressure than we felt any other time.
Lawrence Keusch - Morgan Keegan & Company, Inc.: Okay, great. And then lastly, I think you mentioned that hemoglobin sensor sales were up 50% year-over-year. Again, if you could just sort of speak to were they up sequentially, which I assume they were. And kind of, again, what's driving that big year-over-year increase?
