Thank you, Mike. Happy to take the question on competition. Look, first of all, we have delivered an outstanding 2024 with 11% growth operationally at revenue of 15% adjusted income. If you look across our key major franchises, we delivered double-digit growth across all three of those major franchises in derm. And we're -- in the context of derm, more than a decade in, we're delivering 17% operational growth. Actually, as we usually do with our guidance as we start the year, we take into consideration a number of factors. We have multiple sources of growth. And while we're not providing individual product guidance, what we're saying is these three major franchise areas, we expect to drive double-digit growth for us in 2025, and we see the underlying trends that drove our performance in 2024, carry us into 2025 with momentum. Now, in terms of competition, we are factoring in various scenarios in terms of what competition might look like. In the case of derm, we expect those -- that to be in the second half of the year, again, not providing individual guidance on derm specifically, but certainly, long term, we expect to continue to drive substantial growth in these categories. If you look at derm, for example, we're estimating 20 million dogs globally that are not treated or undertreated. We're treating about 12 million today with Apoquel and Cytopoint, there's still 7 million that are on other therapies like steroids, for example, another 13 that are not getting a prescription choice. So clearly, the opportunity that remains here is actually pretty vast and that gives us a lot of confidence in terms of our long-term growth. In terms of investments, look, I think you've seen us do this quite well. At the same time, we are leveraging other investments we made in our field force, et cetera, to drive operational leverage through the P&L. In the case of putting support behind our key brands, whether it's DTC, whether it's education of veterinarians, et cetera, that's something we have demonstrated an ability to do, and they have great returns for us when we do that. We have significant measurements that shows that. And those are areas that we are factoring into our guidance from a spend standpoint.
