Yes. I would mention a few things. One, I think our brand continues to improve and as -- on notoriety as a result as our brand improves, we were able to work on more transactions and bigger transactions with bigger fees. And that, I think, has just been part of the DNA for years. Two, as asset values have increased, the size of businesses that we're selling today are just bigger than they were six months ago, a year ago, five years ago. So part of that is just the escalation of asset valuations. In terms of the productivity per se as it comes down to whether you do this per MD, per employee, so I think we and others have clearly benefited by the lack of travel. You just get a lot more done. Effectively once the marketplace is willing to do transactions remotely, then our bankers were able to do everything remotely, and they didn't have to go to the airport. They didn't have to be on the planes. They weren't going to meetings. And we do expect some of that's going to come back. So all other things being equal, it will eat a little bit into productivity when that occurs, but I do think there's probably some longer-term fundamental shift where the method and types of in-person meetings are needed. We may never come back completely to where we were pre-pandemic, but hard to believe that fiscal '22, '23, '24, et cetera, is going to look like it was in '21. So I think some of those things are still positive to our productivity level. The efficiency level of people, you have to assume at some point, we will start traveling again, which is a negative. And the last thing I'd say is as the last class of new hires that we had, especially with the junior level, we train them as best we could, but training them remotely is never as good as an in-person. So I actually think the most junior of our team members will get much better once we're all back in the office and once they can more easily work with their colleagues, and that probably has an improvement in productivity.
