Yes, I think a couple of things there. One, they do have - the things we work on, coker drums, reactor vessels, that's where our critical service value-add is really, where our technology comes into play in a big way. These are huge investments for refiners and oil companies, and so they are going to maintain them. They also can become safety hazards at a certain point. So they're definitely going to maintain them. And the question is - and quite frankly, a lot of them had been pushing their turnarounds on some of these components for a while already. So I think we're in a situation, it's only a matter of are they going to pull them down in the fall or are they going to wait till the spring? It's going to - and I think in most cases, it's one or the other. There's one school of thought that says, well, why not pull them down? Demand, low so they don't need the production. So pull them down, maintain them, they're good for three to eight years after that. So why not do it? On the other hand, it's like, well, but if you're margin constrained anyways, why not wait and save the maintenance cost? So those are the two schools of thought. I think every oil company's probably making those decisions around their particular set of conditions. Internationally, our only concern is where we do a lot of work, up in Canada, down in India, for instance, over in Southeast Asia, it's just a question of whether they allow the travel. It's - the one difficulty is on some of these sites, where they're not in highly populated areas, they have to have work camps. And so obviously, with work camps, you get concerned about the social distancing and the number of people in effect a Quonset Hut. So it's just tough. We're - I wish we could give you more color on it. We're seeing good quoting activity. We're seeing lots of the upfront work that usually goes on, that would preclude a good thought, but that's just kind of where we're at. I think that's about as much color as I can give you. We're - we should know - usually these things, if they're going to go in the fall, we'll know by the end of July or middle of August, when they start doing the engineering work and getting us to - a lot of these jobs takes two to four weeks to do the prev work to get the equipment ready and all that. So, we anticipate within - over the next four weeks or so, we're going to have a much better idea of how that falls stacking up.
