Yes. So, Scott, you're right on the progress collections. We have built up that progress collections liability as we've increased our orders particularly in Turbomachinery. But as we talked about specifically we look to keep those projects free cash flow positive over the life of the project. So look, I don't expect this decline in the liability to be a materially large cash drain in 2021 or 2022 at this point. And a few things to think through. Look, the increase that you have seen will draw down over the next two, two and half years, as we mentioned. Look, you can still clearly see the progress liability on the balance sheet, but what's harder for you to kind of untangle or partial offsets is just on the asset side. Typically, when we get an upfront payment, we place orders for long lead items, we bring inventory in and build up inventory on our project. In addition, there will be some receivables associated with that project as well. So it's not exactly a one-for-one in terms of the cash flow impact that you see in the progress collections line. Another consideration, as you mentioned, is what the future awards are going to be like over the next couple of years. So look, based on the project cycle, where we are, how each of those projects should perform from a free cash flow standpoint. Again, I don't see that being a major drag as we go into next year. And then around OFS, you're right, as activity levels increase, typically, you do see a working capital drag. A couple of things I would highlight. As part of the work we've been doing in OFS over the last couple of years to really drive better free cash flow performance we've made a step-function change in both the collections and order to remittance process, as well as the inventory input process. And feel good about the new processes that we have in place and that we'll be able to manage incremental volume while continuing to improve our inventory turns, as well as our days sales outstanding. I mean, we've made great improvements since coming together in 2017 and there's more that can come there. So we're all incentivized on free cash flow. It's the largest piece of our short-term incentive plan. And we've got pretty good processes in place to capitalize on that as volume returns. The other thing I would mention here is OFE, in particular. We're in a cycle in OFE that's probably been more of a draw on working capital just given where the projects are in their execution phase and that should turn around as we go into next year as well.
