Yes, Charles. We're not giving any guide on first half, second half like we have before. I think because we are entering a new dynamic from what we've all experienced over, let's say, the last three years, 2020 through 2022. Right now, I've been in the business 10-plus years and I'd say, it does feel like we are back to what we would call normal seasonality. I'll also caveat that by, there's never been a normal season in the business when you think about the weather impact and late spring or early spring and same thing with the winners in the fall months. But what I can say is, if we rewind the 4Q last year, let's set that as an anchor point, where that felt like a normal 4Q for the business going back pre-2020 timeframe. 1Q and what we've laid out for guidance, again, kind of when you think about revenue on a percentage basis of the full year, where we're sitting for 1Q with the guide, taking into account seasonality, but more importantly, does that continued destocking of the package pool piece of the business, 1Q would kind of frame back up to a normal quarter for us. So if you use those two anchor points, both peak building season for us in 2Q, 3Q with 2Q typically being a little better than Q3, first half-second half dynamics, I've seen them swing by 4 to 6 points over the year. That's why we don't want to quote it. I think we want to just really get through the first quarter here. And see how the macro environment plays, how the demand pull-through for our dealers and consumers happens and then when do we start to see restocking orders in the packaged pool world. And, look, we're going to continue to drive fiberglass far; we get a lot of new deals we signed up last year and this year and that will be a big focus for us to try to deliver what we've put out there for 2023. And just quickly touch on the EBITDA aspect of that seasonality from the revenue, if you think about the cost basis of this business on the fixed side and the variable, right, we do carry higher cost in 1Q than 4Q on those much lower volumes, which is kind of knocking down the EBITDA level that we saw last year in 4Q and that we're indicating here in 1Q. And then, clearly, there's a strong bounce back in Q2 and Q3 when the volume picks back up, running through the plants for us.
Charles Perron-Piché: Thanks for the color. Appreciate it.
