Sure. So Advanced Materials, oil is sort of - ultimately drives a lot of the raw material costs for pretty much the entire segment outside of the cellulosic products, Duffy. And so in that area, you have that potential. So far, we've seen great price stability through all last year, right? Paraxylene was a tailwind all last year. Prices have been holding up relatively well. Starting to give some back. To be clear, as we've said in many calls in the past, you don't hold on to all of it, right? You've got to treat your customers with respect and share some of the raw material value, and we're going to do that. But still, net, I think it's going to hold up quite well from what we can see. And things like Tritan, where we're the only competitor in the world, we've got a lot of control over pricing. On the auto-related markets. Interlayers is annual contracts. So those prices got established last year. So they don't have a lot of movement to them when it comes to raw materials within the year. And then in performance films, it's also very price stable. They - it's a consumer product, and our prices are pretty stable there. The value that we present in performance films is not remotely connected to raw materials. So overall, I'd say that segment, it's going to have some prices come down a bit this year with raws, but hold up really well. In AFP, if you go to the two third of AFP that we called out. So coatings, specialty fluids, Care Chemicals, crop, et cetera, that's actually going to have pretty good price stability, has had good price ability through last year and expect it to continue to have really good price stability this year. There are some cost pass-through contracts in Care Chemicals and coatings that we'll pass on some of those raws, but the spreads will be stable, which is in the end, all we want from a long-term point of view. But you'll see some of that impact. That's about 2% of the 6% for the overall segment as those cost pass-through contracts for the first quarter, as an example. We will see some increased price competitive behavior in adhesives and tires in the one third, but that's also sort of stabilized. They got very competitive by the back end of last year. And I don't think spreads are going to compress a lot more from that to this year. So overall, I'd say we're in pretty good shape Duffy, to either neutral or improving, even in this environment. And that portfolio, Fibers, is totally different, as you know, where those prices at 1% down will be that for the year. And in CI, I think I've already addressed.
