So, we haven't guided [indiscernible] cash flow, but let me make some, Andrew, comments to help give you some incremental perspective and insight as it relates to that. In our numbers for the year 2019, at the end, there was a chunk of cash that openly went out excluding the receipt of the proceeds from ECR, but a lot of the other cash, whether it was restructuring or taxes or whatnot, probably at the end of the day, over $450 million for the full year. So, that's another point that's going to, obviously, start to significantly go away. I would say Q1 is still going to be a fairly large investment profile in the restructuring and efforts to disassociate and separate the businesses as we exit from our TSA arrangement with Worley. So, a big chunk of cash will go out in the first quarter and that will start to tail off in the second quarter. Probably have another $50 million plus of costs mostly in – I would say in the fourth quarter, I would say – our excuse me, our first quarter of 2020. CH2M is effectively dwindling to not much. And then really what we're talking about is the incremental stuff associated with KeyW and Wood, which we've already talked about in terms of what those one-time costs are.So, while there still is a chunk of, let's call it, restructuring related activities, less than 100 probably, but certainly a heck of a lot less than what the numbers that we incorporated in 2019. So, our cash flow as we enter into 2020 and then get to the end of the 2020 is going to become much cleaner and more operationally oriented.If you kind of peel away all of the one-time items that were associated with our significant transformation, and I would say 2019 is the year where all what's happening at the same time, finishing up CH, driving ECR, that fundamentally, if you'd peel way all of that, we were kind of approaching 85% maybe of conversion factor relative to the income levels, the net income levels associated with that after adding back amortization. So, that is a baseline in my mind in terms of how we would think about driving our business going forward from the cash flow.I said to you in the past and I think that's certainly our view is that, our expectation is that, over the course of 2020, we're going to be able to get to that conversion factor that we've talked about at 1 times.
