Hi. Thanks for the question. Two quick ones on IP with DMD. Obviously, there's an interference going on in the U.S., I think you made some comments, but if there is a situation where obviously you win and both drugs are approved, how should we expect you to proceed? You've mentioned the word blocking and that kind of stuff, but what would be the scenarios that you would take in that situation if both were approved? And then my second question for Hank was, in gene therapy, can you just reiterate, again, how you picked the dose and whether you're confirming that there would be disclosure on data, yes or no, whatever it shows by the end of the year? Thanks.
Henry J. Fuchs - Chief Medical Officer & Executive Vice President: Well, let me – I think J.J. wants me to start first. So, we picked the dose based on an extensive study in mice and then in non-human primates evaluating different capsid types, different codon optimization schemes, different vector constructions. And then, we looked at the relative efficacy achieved as a function of dose across the spectrum of mice and monkeys for factor IX to get a sense of base – I'm sorry for, yeah, for factor IX. So, based on sort of the three dots of mice, monkey, man in factor IX, we're estimating for factor VIII for the capsid type, the gene construct, the codon optimization, and the promoter, we're estimating what the target efficacy would be for a given dose level administered to humans. That's – and as I said previously, the goal would be that the first dose would actually be an efficacious dose. But, of course, that's an extrapolation based on factor IX and that extrapolation may or may not hold up for factor VIII. I think we'll announce first patient in when that happens and I think during my prepared comments I said that we expect that to be imminently. So, I think if you hear an efficacy statement from us by the end of the year, you can conclude what you can conclude from that efficacy statement. I think if you're not hearing anything about conclusions to the experiment, we're still at work, would be the conclusion to draw.
