Sure. Great question. So look, we tend to look at, in simple terms, the M&A market is a function of availability, and financing, valuations, confidence level amongst CEOs, boards, investors, and then very importantly, what are the catalyst. Today, and, frankly, financing is available as ever, I think as you get higher interest rate, it really depends on whether or not that chokes off financing. If you're in a reasonably strong economic environment, unlikely to be the case, so that's something you know, to keep an eye on. But I think, you know, the economic environment probably remains strong through ‘22. So that probably means that we're in a reasonable financing environment then. Equity valuations, look, they're a little over the map, there are sectors that are heated, but then you see more equity being used in those sectors. There are others that have been behind and cash is still a very effective way to make deals work. Confidence levels are really improving with the improvement in the economic outlook. And that should be sustainable for a while. And then the other piece that I think is a real driver of M&A activity is the catalyst. And here we've got a couple now. One is been in place now for the last year or so which is this real technological change across every industry, and they need to really improve competitive positions through M&A to adjust for that. And the second, which is a Neuro One [ph] which we're starting to see quite a bit of activity around, especially in Europe is around the move towards a carbon-free world, and the adjustments that need to take place around that, and investments in core businesses or new businesses to better position. So I think those are going to be fundamentally strong factors. Obviously, if we start to see interest rates rise and markets close, that's something to keep an eye on. But for the moment, it feels pretty good. And the Fed and the central banks across the world are very focused on keeping those markets open. Tax rates, look, it's a little early to know. I think, you know, by and large, the corporate tax rate probably ends up going up a bit. But that doesn't look like it's going to have much impact on activity levels. Personal tax rates a little more uncertain, is that what happens there. And obviously big moving capital gains could have some shorter term or medium term impact on the market. And then the global tax rate, that's probably much further out because that probably - at least as I understand it, requires renegotiation of tax treaties. So it's not probably something that we start to feel the impact on in 2021, or even to 2022.
