Thanks, Jamie. Again, overall, if we look at the AWP business, we believe they built momentum over the year, culminating with a stronger Q4. And what we're seeing is, stronger underlying markets, our customers, are really seeing improvement in their utilization in the rental rates. We also believe that - Matt has talked about the replacement cycle now for many years, that replacement cycles trough is winning and we're entering a period of growth. And really, as we see it, looking at the backlog, that's really a broad-based growth across North America, Europe and Asia is driving that. And so, as we look to the margin side, the markets do remain competitive, but clearly there is a more favorable pricing environment, especially compared to recent years. We're able to get a modest price improvement in 2018, especially in our national account agreements, as compared to negative pricing that we saw in 2017. So, the margin improvements are going to come from some modest price increases, improved productivity on the higher volume, is what's going to drive the incremental margin improvement. And last, I'd say, the team has been working hard, Matt's team on the commercial excellence side, really trying to have the process discipline managing the pricing waterfall to ensure that we're not having any leakage on the pricing given that the dynamics in the market place is challenge. So, we're getting the modest price increase to cover some higher input cost. Matt and the team are focused on meeting the needs of the customer while expanding margins. And then Jamie, I think on the last question, clearly, we're just trying to give 2018 guidance, and I'm trying to give 2019 guidance, but in the AWP, Aerial space, this replacement cycle, we've talked about it now for years, and as you look into 2019, if this replacement cycle is waning and that's our current look, it would require that we'd build the little bit ahead if you will of inventory in the fourth quarter. And so, we're trying to provide full year cash guidance. And so, we thought that would call out that we needed to produce a little bit higher. Again, that's based on our current view of the world in the replacement cycle coming to an end.
