Okay. Great. Yeah. So, let me take the first part on the shape of the recovery from the market aspect. And then I'll let Don talk about kind of the shape of the recovery from the API perspective in light of the transformation that we're going through. So, that's how it will help get to that answer. I think when it comes to the jet engine materials, you're right. Our isothermal forgings are really kind of the leader of the pack for us in terms of the jet engine business. We've started to see -- I guess, during the downturn, our jet engine customers were pretty aggressive at adjusting their supply chain inventories and the demand pretty quickly. And so, we don't see tremendous amount of inventory in the pipeline. We have a little bit of stranded inventory ourselves that we're working through. But you're right, the isothermal forgings will go -- will kind of pace with increases in demand pretty quickly. Lead times being what they are. We're starting to see real demand coming back. I think, it will accelerate through mid-year and be stronger in the back half, that's coupled with some share gains that we have coming into 2021 as well. So, I think that the isothermal forgings will be our leader of the pack. We have some smaller aerospace forgings that will go along with that. We're not in the castings business anymore, so we don't have quite as much visibility there, but I would expect they'll follow a similar trend. When it comes to billet, bar, ingot, we're starting to see what I'd call emerging demand. One of the things that happened in the downturn was that every company -- I hate to say every man for himself, but every company was doing what they thought they needed to do to manage their cash. So not everyone in the supply chain that we supply is well-positioned for an uptake. So we'll see it a little lumpy. There should be some good emergency demand, and we think we're well-positioned to respond to that. And you didn't ask specifically about airframe, but I think -- by mid-year, I think the billet, ingot, bar will be moving in the right direction for us. We'll start to see it tracking with engines. But I think the airframe side plate, in particular titanium plate, could be slow for most of 2021 before it starts to kind of work its way. And then 2022, we should start to see some increase there. So, hopefully that helps on the jet engine side. But I think the worst of it for us was Q4, and Q1 is still a little bit of stabilization. We're not seeing the ups and downs that we saw in the order book before. So, Don, maybe I'll turn it over to you and you can talk a little bit about the transformation.
