Yes. I would actually think that right now, particularly given the volatility in the world and answering the question that Rich had posed earlier, with the demands of central counterparties and counterparties on a bilateral basis for more margin and costs, that scale is more than ever a premium. And so firms that are subscale or limited to an asset class are going to continue to, in my view, to be really challenged. And it is very, very difficult to get trading credit, to get capital, to have PBs and FCMs in this marketplace where there's been some well-publicized losses from FCMs and clearing brokers. They're going to be very loath, I would think, to take on new competitors, and they're going to be -- they're going to be looking at their client lists, as every bank and broker is in the world, and we do, right, to cull from that client list, smaller firms that are subscale, undercapitalized and pose outsized risk/reward returns to those clearing brokers. So I think, again, the winners of, as I've said many times on these calls, I think the winners of -- ultimately of this race, if you will, is going to be the large-scaled, multi-asset class, integrated financial institutions that provide market making services, execution services across asset classes and geographies. It's no different than any other business because we take this massive fixed-cost plant that we have built across all these different exchanges, and we're now using it both for -- on an agency and a principal basis. And we're using that same DNA for our workflow products as well, the backbone of Triton and analytics are in process of being ubiquitous with the backbone of what we do in Triton. That type of scale, I think, is going to be paramount for success in an ever-increasing competitive marketplace where you just need that scale to invest and continue to keep improving. I mean, we don't separately break out what our R&D is, right? I mean, obviously, we have a CapEx budget and we expense what we spend, but we spend hundreds of millions of dollars a year, in my view, on technology, both in terms of gear, but also in highly talented engineers that do nothing but try to make us more efficient and able to provide a better service either as a principal or an agent. And that R&D spend is spread across all and current future products that we have, not just equities, but all these other products where we think we can scale our opportunities.
