Sure. So, let me start, I think, first and foremost, Mike, by talking about demand. The demand environment has been softer, particularly in Europe and China. And we have a significant presence in both regions, and in particular in China. China makes around 40% of the world's silicones and, of course, fumed silica is tightly linked to that chain. So, weaker demand in Europe and China and in key end markets like automotive and construction has been a significant impact. In calendar 2019, we estimate the market in fumed silica globally actually contracted. So, this is a market that over time has grown pretty consistently 4% or 5% a year. It actually contracted in 2019, and that was, of course, pre-COVID. So, the further demand weakness is, I think, exacerbating things and driving up competitive intensity in the region. In addition, some supply has come onstream recently, and so the combination of weaker demand and supply coming onstream, which tends to be somewhat lumpy in terms of when it comes on, thereby pressuring the near term pricing. So, while these factors certainly present near-term challenges, I think the fundamentals of the business remain attractive. The business, as you point out, has historically been a business with very strong profitability and high EBITDA margins. And again, demand has grown in this business over time above GDP and that sort of 4% to 5% level because silicones have pretty strong performance characteristics in terms of demand substitution. And then, finally, feedstock access and strategic integration, I think, will continue to determine long-term growth and profit levels. And on this front, I think we're really well positioned with our strategic fence line partners, Dow Silicones. This industry has historically been well balanced between feedstock in Wuhai and silica demand, leading to pretty limited new entrant risk. Now, I think feedstock, as you know, is a byproduct of both silicones production and polycrystalline silicon production. And so, these fence line relationships are pretty critical. You can't just go to the market and buy this feedstock. But capacity additions can definitely be a bit lumpy, given the economic scale of investment here, and demand growth has historically soaked that capacity up in a relatively short period of time. So, I think it's a question of how demand responds, but the sort of industry structure and industry fundamentals remain intact from our perspective. So, it's a demand question, Mike.
