Sure, Kurt. Yes. The $600 million to $700 million is combined for 2019 and 2020. But we won't stop there, I mean, the end objective as Tony and I have repeatedly stated is that we want to get to the low $2 billion mark in terms of net debt, but we still have a ways to go. So, in the first quarter, I mean as you have seen in prior years, our cash flow for the course is fairly seasonal. Last year in the first quarter we had about over $200 million of net debt increase. This year, we paired that to about $100 million. In the first quarter, we do have a significant amount of expenses that don't recur in the remainder of the year as I stated in my prepared remarks. If we take out in the second quarter the $80 million of interest expense, $80 million of dividend, reduction in CapEx, the absence of those one-time events in the first quarter plus the improved, EBITDA, we think just those things give us an improvement of $200 million over the first quarter. And then we also are accounting and targeting some working capital reductions, where we have made some efforts to reduce our receivables, we saw some of that in the first quarter, but we expect to get much more in the second quarter. So all that together means, that we feel that we'd be in very good position in mid-year basically on the plus side, that is reducing net debt by somewhat versus the end of last year. And then in the second half, we expect a very strong cash flow as our results continue to improve. And again we expect a very strong quarter like we did last year. If we compare this first quarter to last year's first quarter, just to give you an idea of the progress we've made Kurt, our operating cash flow from the cash flow statement, as you will see in the Q is about $150 million better than last year. We did spend a little bit more of CapEx this year than the first quarter of last year, maybe some $50 million, but again that's just related to our plans for the year where we had targeted about seven to eight – or total of nine operations in the first half of the year and none [ph] in the second half of the year. So you'll see the second quarter have a very, very strong cash flow generation and we expect to deliver for the full year. Again, the fact that our interest payments are semiannual in first and third quarter, it doesn't really allow us to have like smooth quarter-on-quarter cash flow generation. But again, if you take that into account, you'll see that our operating cash flow is progressing and should be stronger by the end of the year.
