And your next question comes from the line of Brian Singer with Goldman Sachs. Your line is open.
Brian Singer - Goldman Sachs & Co.: Good afternoon.
John J. Christmann - President, Chief Executive Officer & Director: Hello, Brian.
Brian Singer - Goldman Sachs & Co.: With regards to the CapEx and activity reductions, when we think about your cost base and your lowered cost, including on the SG&A side, when it's time to ramp back up, what is your operational and scale flexibility to do this? And what flexibility, if any, may be reduced, at least, temporarily? I mean, in other words, if you wanted to take the Permian and bring it back to a 10 or 15 or 20 rig count again, would this require re-staffing and the passage of time to make that happen?
John J. Christmann - President, Chief Executive Officer & Director: Brian, with the way we've done our staffing, we strategically designed this organization for a $50 plus world. So, we do not envision needing to add a lot of staff to be able to flex back up. Clearly, I think if you get into a significantly lower time period where you've got lower prices, 24 months, 36 months out at that point you'd probably reduce further. But, we've maintained the flexibility so we can ramp up our capital programs when appropriate.
Brian Singer - Goldman Sachs & Co.: Great. Thanks so much. My follow-up is actually a follow-up to Pearce's question on exploration. You made a couple of references to adding exploration opportunities. Was that specifically the Suriname reference that you've already kind of spoken to here or are there other opportunities including the onshore that you're pursuing from a more exploratory perspective? And can you give us more color beyond Suriname if the answer is yes to that?
John J. Christmann - President, Chief Executive Officer & Director: Well, I mean, it obviously includes Suriname. We did a good job of highlighting our North Sea exploration program last November, so we've got some exploration wells to drill in the North Sea. We brought on two discoveries late-2014 in Egypt in Ptah and Berenice, so we have active exploration programs both North Sea, both Egypt, Suriname and then obviously in North America. We have acknowledged that we acquired some acreage last year at some low prices that we think can be prospective. And while we've shut down for the most part our development drilling in North America, we will be doing some strategic testing in and around our existing asset base, and on some acreage that we've picked up.
