Patrick, relative to the global efficiency program in Massera, so let's go with Massera first. As you know, every quarter I used to tell you how many patients that we had now with multiple doses. We were at about 130,000 patients at the end of Q2. We sit here today at about 131 to 132, so we've had the majority of the conversion take place. I think there'll be some movement in and out perhaps as we go through further quarters. With our GEP program, we are on track for that. We should exit 2016 at a $300 million savings rate. And we do have projects that look into outer years. As I've said before, some of these projects that are built around efficiency in our clinics, in our supply chain, things of that nature, will take a little longer. We're pushing harder. I don't want to say we picked all the low-hanging fruit, but we pick those trees pretty hard. But, we're going to continue to push on that, and I think we'd have to get a little more clarity. Perhaps when we give guidance for ‘17, we can give you some sense of what may be going on with GEP. But, the whole mental process and the effort of being more efficient and looking at all of the types of things that we could find, we'll continue to do that. And your last question, the RFI, here's what I think we can do. Let's not speculate, because I really can't begin to think about what may or may not happen, but let's go back to the facts, as you said, and I appreciate that you brought it up. We've been very clear about the fact we don't steer patients. We don't have a practice or policy that would allow us to do that, and our employees don't do it. We're very transparent in our RFI. We laid everything out for you. I appreciate the fact that you recognize that. We today have not had any walk-across or blowback or impact from what's been happening with other companies, or other providers, in any discussion that we've had with our insurers. Our communications have continued to be good, the relationships strong, and we'll take it from there. But, at this point, we just think we need to keep doing what we're doing and keep our discipline, but I appreciate the fact that you recognize we were the only company that was transparent enough to list exactly what we had to make it clear for you folks and investors that they had nothing to fear from us in that regard.
