Sure. Thanks for taking my question. I have two. First one may be relatively simple. Has your house view of CGRP market size changed post the PCSK9 pricing we saw last week? And secondly, on EBITDA, so right now my understanding is, Teva EBITDA is about $6 billion. Allergan Generics got you about $4.1 billion, so that makes it $10.1 billion. The slides on Monday mentioned $11.6 billion as being the EBITDA in 2018 meaning, between now and 2018, EBITDA goes up something like $2 billion. So I just wanted to understand how you think about the key drivers of $2 billion in EBITDA increase between now and 2018. Thank you.
Erez Vigodman - President, Chief Executive Officer & Director: So maybe the first one, Umer, we are okay with $10 billion market at this stage, although we believe that the commercial opportunity is even bigger. I don't think that there are good enough tools today to approximate the commercial opportunity here, so I believe that over time, we'll realize that it goes beyond that $10 billion bar (31:04). And that's something which is good enough, given also the way we see our position, and even leading position, in that space. Michael, you would like to add something?
Michael R. Hayden - President-Global Research & Development: I think the one way just to look about this is to think about the number of people with migraine in the United States, for example, let's just start here: 70 million globally, a big, by the way, population in Japan as well, very frequent. And in the U.S., around 40 million, of whom 5 million have chronic migraine. So the important thing in looking at the market size is firstly, thinking about the population that suffers from this and secondly, the competitive landscape. And certainly, besides CGRP, a lot of the medications are being poorly taken up, not really providing efficacy, and also with some significant side effects. So we believe that this whole field will revolutionize the field of migraine, just like statins revolutionized the treatment of high cholesterol, and we believe, in just looking at the numbers and also, at the present time, the safety of these drugs. Early days, but still this has been very safe, particularly for the anti-ligand. There's always concerns with the receptor about hepatotoxicity. The market has the potential to be significantly higher than what's stated. But I think we will – obviously lots of studies going on to understand the acceptability, the needs in the patients and – not only in the U.S. but this is huge in Europe and also Japan.
Erez Vigodman - President, Chief Executive Officer & Director: And Umer, on the second one, $0.7 billion from synergies, and the rest is coming from the growth of top line and bottom line of the legacy Teva's and Allergan businesses.
