And thank you. Our next question comes from Chi Chow with Tudor, Pickering, Holt.
Chi Chow - Tudor, Pickering, Holt & Co. Securities, Inc.: Hey, thanks. Good morning.
Joseph W. Gorder - Chairman, President & Chief Executive Officer: Hi, Chi.
Chi Chow - Tudor, Pickering, Holt & Co. Securities, Inc.: Hi, Joe. This question may be the same as Paul's, couple questions ago. But just this RIN issue is kind of cropping back up this year. Do you think there's any vulnerability to the merchant refining model that you have longer term, given the RIN issue or anything else that may be out there?
Joseph W. Gorder - Chairman, President & Chief Executive Officer: Well, it would probably be hard to say that the RIN was helpful to the merchant refining model. Okay? Obviously, it's not. But then you get into what are the options for dealing with it, and I think I mentioned those earlier, Chi. Specifically from Valero's perspective, the retail marketing business isn't something that's currently on our radar screen. We believe there's better ways to deal with the issue. And so I really don't have anything to add to that, but I think certainly it's an issue that we're working very hard to deal with because it does. It puts an expense on the merchant refiner that he shouldn't be bearing today. And so that creates a real problem. It creates an unlevel playing field in the marketplace, and that's never good. So, anyway, we'll continue to address it the way we are.
Chi Chow - Tudor, Pickering, Holt & Co. Securities, Inc.: Yeah. Thanks, Joe, for those thoughts. Maybe a question on Aruba. There's been a lot of industry chatter about Venezuela's interest in Aruba lately. But you've written the whole asset off at this point. So are you suggesting that there's no option going forward to sell or transfer the plant to another operator?
Joseph W. Gorder - Chairman, President & Chief Executive Officer: I'm looking at Jay to see what we say about this.
Jay D. Browning - Executive Vice President & General Counsel: The option to transfer, it's still there. I mean, it's just a function of the financial requirements we've chosen to write off.
Chi Chow - Tudor, Pickering, Holt & Co. Securities, Inc.: Okay. So you can still transfer, but for free basically, is that kind of what you're signaling?
Joseph W. Gorder - Chairman, President & Chief Executive Officer: Yeah, I guess so.
Chi Chow - Tudor, Pickering, Holt & Co. Securities, Inc.: Okay. Great. Thanks for that.
Joseph W. Gorder - Chairman, President & Chief Executive Officer: Okay, Chi.
