I mean the demand in the fourth quarter was still up on a global basis over the prior year and the prior year was a very strong fourth quarter. But as Al said I've said, I mean, we've seen some moderating. And also the market was very heavily to started last year because of the -- again, because of the price increases, some manufacturers are putting in place where people were pulling forward orders. So again, global demand was up a couple of percent, the Americas was down in the fourth quarter, but we're not overly worried about that. Again, because we saw very strong quarters earlier in the year in order to beat the price increase. Our markets in Brazil, which was an important market for us, is really recovering nicely, was up almost 40% in the year-over-year. The European markets were up, Western Europe was up a little, Eastern Europe was up a lot, Middle East and Africa was down and even the JAPIC markets, China was up a couple of percent in the fourth quarter, I mean significantly down on the growth rates we've seen of late. So we see markets moderating, but as be probably see markets continuing to moderate going into 2019, but we're still looking at a very strong market. And as far as the Big Truck demand is concerned, I mean it was very strong in 2018 and we expected to continue to be strong, maybe is not quite at the levels of '18 into '19. But again, we saw a very strong demand from around the world. And we look at it by segments to Al's point, so we look at what's happening in ports and terminals, we look at what's happening in steel, we look at what's happening in mining, we look at what's happening in concrete, we look at what's happening in a model. And most of those segments are still very robust. And so we don't really see any decline, significant decline in our demand. In fact, as we're stopping in our lead times and as we go through the first and second quarters, we're hoping that's going to actually provide us a stimulus going into the second half.
