Yes, great question. The reality is the growth of our options is accelerating growth in our future. As we mentioned before, it's a sticky value proposition for customers that are using options in their portfolio hedging and the cross margin efficiencies they can't get anywhere else. To your question on the kind of spread of participation across our client segments, this is a broad set of participants that's driving growth. We -- as I mentioned before, buy side, in a record quarter for us, our buy side participation in options was up over 40%. Props are up in kind of the mid-20%. We saw growth in retail. We saw commercials and banks participate. So, this is broad-based participation. As I mentioned before, I can't stress enough that the reason the customers are using options here is because they're adding increasing amounts of that to their portfolios out across the curve. So, Tim mentioned the position that we have in open interest in the equity side of the business. We're seeing that growth across all asset classes as well. What I think was mentioned briefly before that with the overall franchise being up at record levels, our non-US growth is even faster than our growth inside the US, growing at 30%. So, we see growth across client segments. We see growth across geographies. When you actually look at the rates of growth out across the board, we saw our EMEA options business up 41%, our LatAm options customer business, up 29%, and our Asia-Pacific business, up 16%. So, as it relates to the sustainability, it relates to the client efforts, it relates to the front-end work we've done in CME Direct, which is our own front end. We've got record participation and record revenue generation through our own front end, which is expanding access to client base, either directly through our connection to us or for our partners as well. On top of that, we've been continuing to build option-specific sales assets in our regions in Europe and Asia. We're seeing the fruits of that. Julie can speak to the sales campaigns that we execute in any given year and the staff that we have that's out not only training customers on how to access our front end but with a significant amount of educational resources that were put in place in Europe and Asia to draw more customers US to increase their participation in options across the board. So, hopefully, that addresses the kind of the growth and scale of the opportunity set. We continue to see outsized growth outside the US. And we'll continue to grow and develop those products that suit customer needs.
