Look on the FRE outlook, it's obviously positive. Stepping back, I think qualitatively there, four or so key fundamental drivers that most you're aware of to our FRE momentum. First is expansion of our existing strategies on vehicles, we continue to benefit from that in the first quarter. Second, as we talked about earlier, exceptional innovation of new businesses, which are scaling and beginning to contribute to profitability nicely BXG, BXLS being good examples of that. Third, potential capital, robust expansion, transformational effect on our earnings power given the perpetual and compounding nature of those assets. And then, fourth, your point, a strong margin position, which we'll talk a bit more about in a second. We put out a target once in Investor Day in 2018 as you know, as you all know, well, $2 for the full year 2021, we achieved that a year earlier than expected and one quarter into this year, we're at $2.20 LTM so 10% above that $2 level. So from here, we just say that we're very confident in our continued everyday momentum given the dynamics, I described. On margins, Bill, just to help you a bit, first quarter, looking at any one quarter, as you know, is there's always a bunch of different factors. The first quarter had a number of positive factors, strong operating leverage revenues growing well, in excess of expenses. We had comparisons against fee holidays in the prior year in private equity, the new business is ramping I mentioned. And then, the sort of COVID teeny effect or benefit, which we're all rooting for expecting to reverse later in the year. And in terms of the outlook, we don't want to focus on any one quarter but more over a full year period. If you look in that vein, at the LTM margin, it's approximately 54%, Bill. And I'd say that's a reasonable reflection of an approximate run rate for the full year at this point. So hopefully, that's been helpful.
