Thanks, Kathryn. There was a lot wrapped up in the question. I think that the first part of it was related to the trends that we're seeing in the marketplace and a sort of belief in our optimism. Look, obviously, we said that we believe that volumes will be down year-over-year. We think that, as we indicated in prior calls as well, that is primarily related to new residential construction that we think will be down double digit plus. We do think the reroof market on the residential side will be down mid-single digits, give or take. And commercial, we still believe that we're going to see about a flat market. We are anticipating we've had lower levels of storm over the past couple of years, and we're expecting that. The way we're forecasting it is to return to the 10-year average. So we see a little bit of it lift in that. And obviously, with the storms we saw in Florida at the end of last year, the weather that we've seen in California over the winter and sort of continuation of some of the storms that hit the Midwest, the Upper Midwest last year. We expect all of those markets to be relatively stronger. Obviously, the sentiment coming out of the first month of the year. I think there was a lot of commentary about the builder show being much more positive. Certainly, our contacts in the builders in the building community are much more positive than they were perhaps two or three months ago. So we're seeing that trend come through. I would say we're not seeing that in the business today. It's still obviously down, but it is also February. But I think, overall, what we're also seeing is execution on our initiatives. We're seeing the traction that we expected to see that we got from the plans that we announced and the actions that we've been taking. We're seeing great results. We're seeing terrific results from the acquisitions. We were terrifically pleased to add 10 green -- sorry, 12 greenfields in the fourth quarter. I don't know that we can keep up that target pace for a whole year. I'm not sure that would be the right answer either. But those are going to contribute more this year than they did last year, and we're going to add additional greenfields in this year. So we've got lifts from those activities as well. So overall, I feel like we're executing very, very well. I think that we're seeing the customers respond to the improved service levels we're delivering on. And overall, it's a healthy market. I mean, the overall levels of market demand, while down from the last year, 2 years, there's high levels relative to pre-pandemic and we think they're constructive markets. I'll let Frank weigh in on inventory levels. But overall, it's pretty positive.
