Yeah, Julian. I would characterize it this way. You may recall, in the last quarter conference call, we kind of outlined what we are doing this year, you know, there's $80 million kind of cost reduction take out for 2020. And we characterize that as kind of three components, which was the discretionary, variable, structural, permanent type of cost savings. And if you look at those specifically on the permanent structural cost savings, to answer your question, we've been added, you know, pretty solidly, I'd say, over the last couple of quarters. We're now hitting, I'd say a full stride, in terms of the cost takeout associated with that. We've identified some additional measures as well, that will help us into 2021. So there's carryover benefit, particularly in the first half of 2021, that will help mitigate some of these variable components that Boomerang back next year. So I look at those, you know, maybe we're a little upside down. If you kind of look at those two independently and sum them up. We will continue to evaluate our cost structure going forward and adjust as necessary. Basis of future demands are always looking at that. However, we will continue to invest in the business, that's a core part of our strategy, particularly on the seamless access and growth opportunities associated with that, to really position us well on the growth prospects associated with that going forward, as we exit COVID-19. So there's going to be some pressure there relative to those components, and then you're going to have unfortunately, unfavorable mix associated with strength in residential, better than anticipated and some continued softness associated with the no-residential markets.
