Yes, Humphrey, what probably would help is if I give you a little bit of color on the 2020 expense actions, and then view into fourth quarter as well as 2021. So again, we continue to reiterate, as we did last quarter, that we expect about $250 million from what we anticipated coming into the year, and we've experienced probably about $200 million of that materialize through the end of the third quarter. That does ignore any adjustments to variable expenses that naturally flow with revenue changes, such as investment management fees, bonus pools and alike. We think about half of that reduction is what we would call staff-related expenses, so that can come from lower incentive comp, lower benefits, reduced hiring, as well as salary actions that we took earlier in the year. And the remainder is non-staff related. So that's where your travel, your contracting, consulting spend, advertising spend would come in. If you take the -- we had $200 million year-to-date, $250 million. You're correct that some of that, third quarter, we think will be the high point of that expense management. But we actually do still see that some of this persists in the fourth quarter as well as into 2021. Just a reminder that we do have seasonality that always causes fourth quarter expenses to be higher and we do think that will be somewhat muted, but we still expect that to be -- show that seasonality as we go into fourth quarter. As we think about 2021 and I think about what is causing and leading to the expense management picture that we have, you're correct, some things will reset. Probably the perfect examples of those is incentive compensation and salary levels. But other items like staffing and travel will increase, but at a lower level than what we would have anticipated pre-crisis. And so if I kind of do the exercise, the same way I calculated the $250 million, which is how do we think 2021 expenses will look relative to what we would have thought pre-pandemic? they're about down about $100 million from what we would have expected. So that implies that about 40% of that $250 million remains as we go into 2021 and that some items will reset at the beginning of the year, and others will trend up as we go throughout the year. This is an early look at expenses for 2021. And obviously, we've had a lot of volatility in revenue over the last 6 months. So we'll continue to evaluate, we'll continue to refine. And our ultimate aim is to align expenses with revenue and ultimately generate the targeted margins that we've shared with you and the investors.
