In our assumption for purposes of trying to assess development activity, we're still in roughly $55 a barrel. And to put little bit of a finer point on it, with the exception of the Permian, we're basically assuming that producers grow within cash flow. So, if that $55 turned out to be $50, we would moderate our assumptions of the rate of development. If it went up, we would expect them probably to get a little enthusiastic. In the Permian, I don’t think we took a very long lead off first, but we assume basically that they would out-spend 5% in the aggregate of cash flow. And it's the rate that we're seeing right now that may be a conservative assumption. Again, I don’t think it affects our 2017 performance, but it may put a big smile on our face in 2018. As far as prices, we're we don’t have any better crystal ball, in fact we have a lot of data. And there is a trade-off out there. OPEC needs to do, what they said they are going to do. And if they do, we should come into alignment somewhere in 2017. Inventory levels are high, but they tend to be concentrated in the U.S. And even if more so but we’ve also become probably the manufacturing center for gasoline worldwide. We’re exporting probably this year total products, including propane about 1 million barrels a day of what we did last year, about half of that is gasoline. And so you need more inventory to be able to be an effective manufacturing operation. As far as the border adjustment tax, I got to say, it's an average so many things about how it's going to work, or how it's not going to work, ask them to come in. I think we’re just going to stay tuned. And once we think it will have the biggest impact on obviously and these are refiners unless there is an exclusion there, how it affects them will create both opportunities and headaches for mid-stream. But we get paid to move barrels. And whether it's an imported barrel or a domestically produced barrel, I think we’re indifferent. Obviously, we want to see as much in Permian as possible. But as I said in my earlier comments, we think the Permian probably perseveres, almost no matter what happens with price, but we’ll supply demand balances, because it's just such an economic barrel.
