Yeah. I think that there's at least a small amount of seasonality. And that has to do with things like SEC filing fees, annual fees, our audit costs, our training costs for the analysts and associates that arrive, et cetera. And so, I think there's at least a small amount of seasonality in that figure. And you mentioned travel. There's also upward pressure, right? And so, travel in the most recent quarter was -- and this is measured by number of trips, it's about 95% of where we were in the first part of 2019, the pre-COVID year, by 95%. Now that has to be adjusted for the fact that our headcount is up about 23%. And so, what that -- on a headcount-adjusted basis, our travel is at about 73% of where it was pre-COVID. And we're closely monitoring that and trying to form a view on where we think that will ultimately reach full normalization. Might be -- there may be some continued normalization as we move forward, but as you mentioned, we're happy to see that kind of activity because that means we're out there servicing our clients. And so that's one thing. Second thing is there are professional expenses that are related to increased revenues. And that's another type of expense we're happy to occur, which is expenses that are around the winning of new business and the execution of deals. Lastly, what I would mention is, and this will get to your answer as to how you ought to think about it going forward. There's a very close correlation if you look at it over a number of years with respect to headcount and non-comp costs, right? And so, it's not perfect in the short term. But in the medium to longer term, there's a very significant correlation. If you look at that metric for us from pre-COVID period, which is 2019 through the present, the increase is about 7%. That's non-comp cost per employee. If you look at that on an annual basis, that would be less than 2%, which is below the rate of inflation. So, we feel like we've done a solid job to-date. And we, of course, realize that with certain upward pressures, and we talked about travel and professional costs and there will also be some investment in technology and information services cost adds a little pressure. So, you can rest assured that internally, we've mobilized our troops and are exercising significant discipline as we think about those non-comp costs moving forward.
