Yes, yes, a good question. I mean, so actually what you see is that -- so I started by saying that we see a very solid growth -- actually, accelerating growth on the medical side, and our medical markets are very strong. So Vision being predominantly medical-focused will be a significant contributor to growth in 2019. And so we expect all the businesses in there to be a solid contributor, right? So let's start with that. And so then Precision Motion, of course, comes off a spectacular year, right, at 25% growth. I mean, that's -- so we have tough comps and it's hard to continue that. In addition, there is some softness there in search and microelectronics markets, right? So overall, at the company level, microelectronics is less than 10% of our revenue, right? But that market is soft or down, right? So that's a modest headwind for us. A bit more of a headwind, I would say, in Precision Motion. So in other words, Precision Motion will -- growth will moderate as a result of both the tough comps as well as this microelectronics, call it, softness. But we still anticipate that it will be a solid contributor to Novanta's overall growth, right? We're not going to get into numbers but we still think it's a solid contributor. And Photonics is basically a tale of 2 stories, right? One is continued solid performance in actually our Synrad and the Cambridge Technology business. And then we're just fighting that headwind in the first half of Laser Quantum that will subside in the second half, right, and for the full year, right? So that's going to be the story there. But I think underlying the message that we want to make is that actually, even within industrial, right, there are many segments that are growing very, very nicely and we're part of those, right? So there are certain pockets, like we indicated, that are softer or down, but the beauty is the diversification of our portfolio, right? We're firing on multiple cylinders. And if one cylinder is not as firing as rapidly, we have multiple others to compensate. And you kind of see the power of the model here that at any particular moment, there might be some launch dynamics, there might be certain softness, but then there's other markets or other technology cycles that will help lift us again. So you kind of see us compensating very nicely, and I think the company's pretty resilient in kind of some of these macroeconomic backdrops.
