David, it's Raj. I'll take the first part of that in terms of the platform -- the broader platform and benefits through this time. And even before COVID, but just on a certainly an accelerated basis in COVID. I would highlight three areas that we -- that really ramped up that helps us, I think, navigate 2020, as you said, in a positive way, and I appreciate that comment. One is, keep in mind, BlackRock has a pretty notable presence, virtually of all the capital markets in all sectors, liquid, private, infrastructure, real estate and a lot of industry insight that's available in the platform, and I think harnessed quite well to take advantage of. And we were literally having cabs daily on cross-asset pricing, on trends tied to the virus and also implications to industries with a lot of internal industry and health care and just authoritative perspective that led us, I think, really put our own private capital portfolio in context, where we wanted to spend time, where we really needed to focus defensively where there might be opportunities. So I think that cross-asset perspective was very helpful in understanding risk and pricing for us in a way that we couldn't have on our own. BlackRock also at its core, is built on a risk management approach. There have -- we talked about this before, COVID and part of our integration. We have a dedicated overlay risk and quantitative analysis team that has, I think, put a lot of good rigor into how we look at our portfolio in addition to the underwriting, and that's just been on an ongoing basis that I think as managers of the portfolio, we appreciate. And finally, even on the liability side, you've seen some of the movement and the changes and the terming out of the right side of the balance sheet as you can imagine, BlackRock's presence with intermediaries both for sourcing, but also for issuing some of the liability and the debt doesn't hurt. So I think, hopefully, that's not just a COVID related activity, but an ongoing one. But in the latter part of 2020, we were able to take some advantage of those relationships to a successful completion of issuance. And I don't know, Howard has any comments on the regulatory side of it, but maybe I'll -- if he does, we can turn it over to him.
