Great, thanks for the questions, just two here. First, maybe a question for John, just updated thoughts on the M&A landscape. I guess specifically, do you see this market volatility as creating some opportunities for Lilly to get more aggressive and look at some assets? And just what's the focus when we think about business development? My second question was on the BACE inhibitors. And just elaborate a little bit more about how you think about the tradeoff of I guess time to market versus the level of BACE inhibition and dosing when you look at prioritizing the Astra BACE versus the internal low-dose BACE that you have as well. Thanks very much.
Philip L. Johnson - Vice President, Investor Relations, Eli Lilly & Co.: Great, Chris. Thank you for the questions. John, you for the M&A. And then, Dave, do you want to take the BACE question, please? John?
John C. Lechleiter - Chairman, President & Chief Executive Officer: Chris, I think the current volatility and generally lower valuations in the biotech sector doesn't change our basic strategy. We continue to look for small to midsized opportunities that complement the therapeutic areas that we're already in that we know well, so I don't think that has changed. We're certainly not interested in any large-scale M&A. At the same time, there's no question that valuations are more attractive today. There are some different dynamics going on. As you know, biotech is not biotech. There's big biotech. There's medium size, and there's nascent or smaller. And so we're looking across that whole spectrum. And if opportunity presents itself based on attractive valuation and what we think would represent good value for the company, we have the wherewithal to move on that.
Philip L. Johnson - Vice President, Investor Relations, Eli Lilly & Co.: Great. Dave, on the BACE?
David A. Ricks - President-Bio Medicines & Senior Vice President: Yeah, so I think your question is how are we thinking about the two programs and decision-making. I think you were there on December 8, Chris, and we spoke about the theoretical differences in the projects. We do know that the AZ BACE and the Lilly BACE that's in the clinic have different chemistry. We really like this target because it's rare to find a genetic validation like this in any disease, let alone Alzheimer's, which has so much unmet need. And so we're investing in two different ways to get there. At the end of the day, the decision-making, though, is going to have to be based on empirical data, because the theoretical differences need to play out in man. So we're collecting those data. A part of that is the AMARANTH Phase 2 program we're running now and the Phase 1 effort on our own BACE. And we'll have to see the data before we make a final determination.
Philip L. Johnson - Vice President, Investor Relations, Eli Lilly & Co.: Great, thank you, Dave. Val, next caller, please.
