Thanks, David. So, look, we've always been a disciplined portfolio manager. It was a while ago when we had our significant portfolio transformation, but we've sold off a lot of underperforming businesses in our history, and we've had very successful acquisitions of great specialty businesses to give the portfolio the strength, not just in the stability of revenue that you're seeing this year, you know, and let's not forget, we started with the trade war and COVID. Over the last two years, we've shown I think, good resilience in the top line with this portfolio, but also tremendous cash flow with the value of the acquisitions. So I think we're good at being disciplined. And as we said, we saw two businesses, you know, tires, adhesives, that were developing instability, that was inconsistent with our strategy, especially as part of AFP, and needed to address that. I think we've made great progress on managing the cost structures, especially in tires, where we're going to take out a couple plants and improve its cost structure in a meaningful way. As well as - and that allows us to level up our new plant, at a much lower cost plant as well in tires. And then innovation is also going really well in both businesses. But you know, the reality is, the tires business is really challenged, and the competitive dynamics. The ADT tariffs that got put in place shoving China tires back into China, then the broader trade war with China kicked off by Trump just created, you know, huge drop in demand, while competitive capacity is coming online. And that just created, you know, a food fight at the tire company level, as you can see, and at our level, with our competitors in this business. So, you know, that's - the volume recovery has been great in the back half of this year. And the earnings, the back half of tires will be much better than the first half. But it's still a competitive environment and a headwind relative to ‘19. And so that's when - we're going to do everything we can to improve the business, innovation is giving us the ability to sustain premiums above our competitors, in a meaningful way. But it's a business where, you know, we're going to continue looking for either JV or divestiture options. And hopefully, we'll get to stability at some point here with COVID and be able to sort of pursue that. But we're committed to dealing with the portfolio. Adhesives is actually holding up relatively well in 2020, relative to ’19, volumes actually up about 5%, price is stable to the back half of ’19, managing costs are like everywhere else. That business is stable, innovations getting a lot of great traction, our IPOs are really winning in the marketplace with superior environmental footprint, as well as better superior ability and allows you to lose less resin. So great growth there. Great growth, we've talked to you a number of times about our low VOC resins that we've launched. So it's stabilizing, but we're also still looking for opportunities to improve its performance if we can, through partnership and how we continue to improve that business. So we're still working, it's not going as fast as we liked at the beginning of the year with COVID.
