Yes, I mean I think, Mark mentioned that system is flushed with liquidity and we try not to cake a view on such large macro factors like overall volatility, where overall credit spreads are moving, with rare exceptions obviously in 2009, when Ellington Financial in fact having preserved capital through 2007, 2008, the toughest time in the mortgage market, and we did take the view that we needed to take a strong view that spreads were way too odd. But we - I think in terms of the more - the bigger sort of as much a two sub-sectors of the market, we're not so keen to just load up on those at huge leverage, right. And then, we've been in fact move in the opposite direction, which is you're moving to shorter duration assets, for example, consumer loans, for example, the small balance commercial distressed loans that we love. And we think that by moving into sectors like that, which is shorter duration and uncorrelated, we can hopefully insulate ourselves from - if this trend does reverse itself and nothing goes on forever, right, where volatility increases and maybe spreads widen a lot. But we don't want to - we never wanted to overleverage and we surely don't want to overleverage in a tighter spread environment. But volatility is low, has - it's always good news, bad news, right. It's - you're right, in terms of our trading strategies. As Lisa mentioned, we're turning over the portfolio a little less, that's combination of both, I'd say three factors. We've got more capital to deploy, to ramp up the portfolio where it needs to be and of course following our debt issuance. So, we're just trying to not necessarily shrink the portfolio, but grow it obviously. We are also not turning over as much, because it's just the nature of the assets that we're - now, more and more of our portfolio is less liquid, albeit shorter duration, which is obviously a mitigant to less liquidity. So, factors like that. I think you'll continue to see our turnover in those strategies of ours to be lower than maybe they were in the past, when we were 80% non-agency RMBS, which was much more able to trade actively and generate additional returns that way.
