I think the sort of the smaller size of the investment initially for us is more a reflection of the fact that the cost of the first trial is not as big as the later stage trials, right? So, it's commensurate with the overall cost of the initial trial, the Phase 2b. And Marshall can add more things to that. But then regarding the question about capital deployment and the fact that the industry requires huge amounts of capital, whether you look at biotech or Big Pharma, and if you look at 5 or 10 years, but it's in the many several trillions of dollars. As I've explained in the past, we see our business with a more predictable, more stable capital deployment that comes from a lot of the deals that we're doing with biotechs – hybrid and synthetic royalties. And we feel confident that those deals, on a yearly basis, will probably allow us to deploy close to $2 billion, somewhere between $1.5 billion and $2 billion. And then, if you add to that one-off transactions that are larger, and you saw this year, one that's quite large with Trelegy or you saw last year another one that was quite large with MorphoSys, $2 billion, those one-offs will increase the overall capital deployment meaningfully. And so, getting from the #2 billion to $2.5 billion that we have guided for sort of $4 billion to $5 billion should happen over time and will also be a function of us having those larger one-off transactions included over the next three to five years, and I think it's likely that we will have those larger transactions. I don't know if every year, but, certainly, over a three to five year period, there will be several of those. But, Marshall, maybe if you want to add anything on the Merck transaction, Merck collaboration, question. And, Chris, if you want to add anything on the capital deployment, please go ahead.
