Certainly, David. What I'd say is we are seeing stable -- I mean stabilization, absolutely. So our guidance is built on thinking that primary demand this year is going to be similar to last year in the sort of discretionary markets. And in the stable markets like personal care, water treatment, consumer packaging, et cetera, we would expect sort of modest growth from last year. Now to be clear, last year's demand -- primary demand was low. We're not predicting an improvement in any meaningful way from those sort of low levels we were at from -- through last year. What I would say is -- and automotive, we actually are -- was growing last year and we think it's going to be more flattish this year. So that's sort of where we are in the primary demand as we sort of showed on the slide that we supplied to you guys. The key driver for pretty significant volume increase for us this year versus last year is really the sort of lack of destocking when you think about the sort of volume mix impact of last year, driving earnings down about $450 million. And what we said in October, I think it's still true. You assume about 1/3 of that is destocking, it's probably a bit more than that but to play it safe, we'll call it 1/3. That's $150 million of a lack of a demand headwind from last year relative to this year. It's like an easy comp. And we can see the evidence of that playing out already in the fourth quarter in some markets and certainly into the first. So for example, the durables business which -- consumer durables business which is the one that was most impacted from a demand drop last year. The second half of last year was 40% higher in volumes than the first half of last year. So you've already seen a lot of the -- into destocking that's occurring there. We're still not where we want to be, of course, from a market demand point of view but it's very clear destocking is over. Same is true in a lot of the stable markets, right? Destocking occurred in personal care, water treatment, things like that in the first half of the year. By the tentative back half of the year, we're already getting to sort of some modest market growth. So for the overall year, demand was relatively flat to '22 in some of those markets. Building construction, I think, is probably still the most challenged. It was tough last year. The expectation is it's going to be tough this year, maybe even slightly down in primary demand. And -- but again, I think most of the destocking in that market has played out. By the end of the fourth quarter, there may be little pieces and parts into the first quarter, so you still get that lack of destocking lift in coatings and interlayers across AFP and AM. So I think that, that sort of on a full year basis, sort of how we look at it. And I would note of that $150 million of lack of destocking, 2/3 of it is in Advanced Materials. And the progression, I would say, through the quarter is looking good. So we had a soft start to January, February is already stronger orders in January and March looks good at this point with what we can see. So that's another point to keep in mind is the first quarter is a pretty slow start, as you can clearly see in our guide. But there's a lot of upside as you move into the second quarter from seasonal build. So we do expect a normal seasonal pattern to demand this year. So even though -- we're not saying primary demand is going to be a lot better. First quarter is always softer. Second, third quarter, stronger fourth quarter obviously comes off in a normal pattern for us. And that is how we've built our forecast around that. So that helps a lot for why things get better in the second quarter. And then there's some timing issues as we've identified in Fibers and fluids where -- particularly low orders in Fluids for especially heat transfer fluids. And then Fibers is a customer buying pattern thing. So those orders get a lot better in second quarter. So there's several things come together along with some better spread improvements that make second quarter a lot better than first quarter, because I'm sure a lot of people have questions on that as you look at our forecast.
