Brian, this is Jeff, and I appreciate the question. So the big drivers of that, there are two components. Obviously, cost per BOE, there's the cost side. And so if you look at the details, you can see things like our downhole maintenance, the things we're doing from an artificial lift standpoint to finding effective artificial lift systems for very high-rate horizontal wells. We're seeing our downhole maintenance cost come down because we're getting much better at finding the right lift systems. And then when things do fail, which they do from artificial lift, getting them fixed cheaper and faster. So that's one area. If you look at what we're doing on the water recycling side, the chemicals side, getting trucks off the road, infrastructure in place, so all the things that we do from our initial developments to where we start planning, how do we need to operate these fields, start to translate into the cost side. The second part of that component is obviously the barrels. We're making a lot more barrels. We're making a lot more lower-cost barrels. So when you look at the cost per BOE of these new barrels we're bringing on, the high-rate unconventional barrels, they're much lower than the legacy barrels, so that helps drive that cost down as well. And Vicki mentioned it, but that's one area we're very excited about. As the unconventional business matures, that's one area where we think based on what we've done in our EOR business and the core capabilities we've built, we'll be able to use that and further differentiate ourselves when it comes to getting margin, by not just good development cost but excellent operating cost, and I think this is a testament to that.
Brian Singer - Goldman Sachs & Co. LLC: Great, thank you. And then my follow-up is with regards to the allocation of free cash flow. You've highlighted the case for free cash flow well in excess of dividends out to 2022. And when you think about the needs for allocation, what if any is needed to advance the portfolio, either from new projects or via M&A versus what you see as returnable to shareholders? And then tangentially, Cedric mentioned $200 million that would have been invested in Qatar is going to be redeployed. Can you just talk more to where that's going, or maybe that was the point that you were making with regards to Colombia and Oman?
