So let me try to address the -- your question, I'm not quite sure I fully understood it. But as I commented, both with Andrew and with Kevin, we haven't seen any kind of market shift in the composition of cases, in the complexity of cases that we've been addressing. What we know as a firm is that, if we could keep SG&A at 13% and we're operating in the mid-70s of utilization, we will enjoy really, really strong profitability like that, that has been delivered now over the last several quarters. But I can't say that we're doing anything different. But one thing that the virtual world has introduced, and we're really quite excited about it continuing, I think we're working across borders, by that, I mean, offices, geographies, more efficiently during this pandemic period than we ever have as an enterprise. So, I think that provides real exciting revenue opportunities, profit enhancing opportunities going forward. And the reason it's profit enhancing is that we are seamlessly using capacity irrespective of where it exists. By capacity, I mean, consulting capacity within the organization, irrespective of whether I'm sitting here in Boston today, whether that is residing in our San Francisco or Berkeley office, or whether it's residing in a practice other than the one I'm situated in. So, all of these kind of efforts does create for a more optimal delivery model, but that is really the only positive progression to speak of. Other than that, it's been business as usual, which is pretty damn good.
