Chris, I'd like to just add to some of Terry's comments and I'll just start by saying that from our perspective, investors analysts have expressed some concern about a potential impact to Royalty Pharma from issues with our CF royalties. Personally I believe it's so overblown the concern for many reasons that Terry already talked some, but I'm going to add some color. So just thinking of timelines, which are really critical here, we're in 2021. If we look at what might take to develop this triple thinking of a trial that is probably going to take a couple of years to enroll, and then 48-week follow-up on patients. So we're talking about two to three years, more likely three years, so 2022, 2023, 2024. Then the trial be completed. It takes time to go through data to file FDA approval. So we're talking about mid-2025, late 2025 for a potential launch. And then obviously, we're not conceding one bit that there's going to be an issue with Kalydeco. We're super comfortable. You have to also just think of the fact that we've been following this for a very long time since we made the investment in 2014. We actually invested a lot more last year when we bought the residual interest and did an incredibly thorough analysis of everything around this investment, which gave us a very significant level of confidence to go ahead and make this additional 600 or some million investment. So we're not considering anything. But just thinking of what may happen, if there is a small shortfall in revenue, when you look at what analysts have projected for CF in our numbers, which is somewhere in the $800 million plus revenue, and if there is a smaller shortfall, just think about this launch in 2025, 2026, for it to get some traction, we're probably looking at the latter half of this decade. And by then, Royalty Pharma will be much, much bigger, just think of the revenues that analysts have projected, analysts estimates by 2025 of around $2.7 billion. And then think, and that's based on what we have today, the portfolio we have today, as you know, we're going to be very active adding much more capital deployed more revenue to our top-line. And we went through the figures of what every billion dollars of investment adds to our top-line. So now if we think of where our revenue might be, by the end of the decade, we're probably looking at something north of $3 billion, somewhere in the $3 billion to $4 billion, maybe more. So if you think of a potential shortfall in one asset of a couple hundred million dollars, it is really immaterial, we're talking about a couple percentage points to the top-line. So that's why I think, this issue has been overblown. And maybe just in summary, I think I'd like to mention a couple of important concepts here. This is an industry that has uncertainty, whether it is competition, clinical study results, patents et cetera. So focusing on any one issue for any one product in our portfolio misses the bigger picture, which is that the strength of our business model and the unique role we play in this industry really makes Royalty Pharma such a highly diversified business with some of the most attractive assets in the industry, and with very high predictable growth. And again just to put this in context, my last slide showed that over the past five years, every billion we deployed resulted in an average of around $170 million in adjusted cash receipts five years later. We've announced over 5 billion transactions since the beginning of 2020, a year-and-a-half. So I think if we project into the future, I think it's important to just realize what's going to happen with this business as we continue to deploy billions of capital every year. And I think I'll just finish by saying that, we went public, we tried to come out with conservative assumptions. But there's no question that looking now, a year-and-a-half, or a year after our public offering, we have a feeling in our, among myself and the team that this opportunity set for us is pretty big. And that's why we're so confident on our long-term growth prospects. So concerns about any single product in our portfolio misses the most important driver of our business. That we add in enough therapies to our portfolio year-in and year-out growing and diversifying our revenue base. I'm sorry to extend myself, but I just wanted to make sure that I share this views with you.
