We have to see a really sharp deterioration, both in Q2 performance and performance outlook for the second half of the year. We've run a variety of models and scenarios for the second quarter to get a sense of what that end of Q2 cash balance would be. And then on top of that run a set of scenarios for the second half of the year. And you have to believe our worst of Q2 assumptions and/or worst of the second half of the year assumption to the end the year was a zero cash balance. And at that point in time, we still haven't touched our ADL, which probably is going to be valued at much higher level, because what would contribute towards a lower second half performance would be rising prices, and so the value of that would be higher. So, we got to believe the worst of the second quarter and the second half scenarios to do that, the challenge of course with CapEx flexibility is every 30 to 60 days that goes by, you've already now committed and started on product, projects or it's too late to pull back on certain projects. So we're looking at Q2 very closely. Everything is going very positively from that standpoint versus our scenarios. And then as we come towards the end of Q2, seeing where we're at then we can then make a decision on, okay, are we going to be in a situation where we need to do that. But I would handicap that as the lowest possible scenario right now. We just wanted to note that we do have that flexibility should the need arise, but that flexibility goes away the longer into the year, certainly you've got 2021 CapEx flexibility, if this thing went on and on and on. And what I would say is, we're starting to see signs of the economy reopening. We don't know if exactly when and how this is going to play out. I will note that, just one day if you look at the government stimulus impact and tax payers receiving checks. Yesterday, we only had four states where our volume was below 70% on a planned basis, and our own state of Arkansas was at 95.7% of plan with dozen states over 80%. So, it's just kind of a note that says, okay, that was stimulus to the economy and tax payers got a check and they went and spent it, and they spent a lot of it with us. But it does give you a sense that, there's a lot of pent-up demand out there. And when it comes back, we expect to see it come roaring back like this and we will get more than our fair share of it, because of how we've treated customers and work with customers to keep them safe and give them value during this period.
