First off, Charles, I would say that in the rand piece that, that was more of a research recommendation than an actually a firm positioning play. And so it was our analysts going out with what they believed was a recommendation around that. And so that shouldn't be read as the firm necessarily having that position. Independent research came out with that. On your second piece, I think as you look at FICC trading, for us, if you look at the fourth quarter and the numbers that we've posted, I think you should look in there, I think relative strength in terms of credit and credit spread products, again, as we measure that against our rates and currencies business, it's not as large. It's still a meaningful business for us but not as large. Some of that other people have spoken to as having outsized, quite significant returns in the leverage lending space. We're not as large in that space. And I think as we look at our trading revenues, we tend to look at those over not just quarter but longer cycles. And if you look at The Street research today, it's indicating that the trading wallet for 2020 was up somewhere in the neighborhood of mid-20s. As you look at our trading revenues for 2020, we're probably up somewhere in the mid-30s. So again, quarter-to-quarter, less important. But again, for us continuing to take share in there and the underlying mix tends to kind of bounce that around a little bit. But again, I think we feel pretty good about our position and the dialogues where we are. I think as we think forward, I think it's unlikely to think that we're going to see wallets up to the same degree, certainly in the trading space that we saw this year. We think seasonality will resume. But as Mark said, as we kind of started and it's early in the new year, we have seen activity remain high. And as I think we see more potential stimulus or governmental programs coming out, the Fed and others continuing to take stances on rates and trajectory and where things go, that could keep trading volumes, keep creating volumes relatively high. So again, we think we're pretty well positioned, and we're in dialogue around those, but we clearly can't escape all of the market dynamics of where the wallets go.
