Yes. Betsy its Eric. The opportunity set is broad and it's a set of initiatives that we had underway. And in the spirit of -- when things are tougher, you've got to act more dramatically, is I think the theme that I share with you. So, if you think about the different areas of our expense base, the compensation benefits line won't be as much of a tailwind as we've, I think, made a very conscious and appropriate choice on protecting our people. But if you think about the expense base, that's only about half of the expense base. And even within the compensation benefits line, for example, there are contractors, there's significant amount of contractors that we employ. And if you think about it, if we're going to end up with a larger employee workforce than we expected, right? Contractors could be an area that we -- where we adjust. So, it's that kind of action. Occupancy is another natural one, whoever thought that you could run a company at a 80% or 90% work from home, but it does give us a real perspective as we have lease rollovers or where we might have been planning on taking additional leases, and there's always a role instead of either potential exits or ads that you're doing as you load balance. You can imagine, we've got lease ads on a complete moratorium. And where we had rollovers, you can imagine, we're now starting to move in the opposite direction and say, hey, why can't I let this space go? And when employees do come back, I want all my employees back, but we clearly have more flexibility than we ever would. So, that's another example. Third one might be around all the other expenses in technology, there's software, there's hardware purchases, et cetera. While our teams are spending time on supporting clients and literally hourly daily basis, it's also a natural time for us to slow some of our purposes of capital equipment or software, doesn't say we won't come back and naturally think about outspending some of that in the future, but it does mean that we can slow some of those purchases because it's -- we've shifted some of our time and energy to more immediate situation as opposed to some of the medium term investments. So, I think that's the other one, which is the -- kind of the reinvestment. We'll naturally slow to some extent. And if you remember the chart we did at the fourth quarter earnings call in January, we showed expenses down 1%. Now, we're saying down 1% to 2%. But within that, there was 3% or 4% increase in investments of expenses due to investments and 4% to 5% decrease going in the other direction. And so part of what we're doing is also, I think, being more disciplined about those reinvestments that we're doing now and pacing them.
