So I'll take the portfolio questions and address one part of leverage as well. So you ask your first question was about the hedges and what we're thinking about there? In general, I think we're favoring Treasury based hedges. Treasury based hedges are liquid. That's something that that we think in general, really offers us a lot of 24/7 flexibility to trade. So futures, is something that you should see be a very big part of our hedging strategy, we've chosen to put our hedges in the back end of the yield curve, given our slight lean towards a steeper curve here to protect the portfolio. So that should also be a consistent theme. I think we've been very successful with using Treasury options and shorter dated options as a -- I would say relatively inexpensive way to manage this rise in yields up to now. In the fourth quarter, we shifted that strategy to including longer dated options into the mix. So we did that a little bit last year, that's something again, that's on the table. As the shorter dated options mature, or expire to go into next year. So you should see that shift happening just as we're rebalancing the portfolio here, In terms of specified pools, into a steeper curve, you should see specified pools start to cheapen as the expectation for prepayments flows and the relative value of a specified pool starts to diminish relative to TBAs. So once we see that type of cheapness come back into the market, I think that'll be a situation where spec starts to look interesting, again. By our metrics, a lot of the spec pools are trading very [sort] [ph] with the theoretical pay ups at this point. And I think there's some risk to -- of higher rate scenarios to those players coming down. So that's what it would take for us to get back in there. And then, in terms of the leverage the way we think about it is, when we returns are sitting in the 8% to 9% range, our leverage will be somewhat in the 6%, 6.5% area, as returns get higher, you should see the balance sheet start to grow. I think that we're prepared, regardless of how this scenario evolves, right? So, for example, if we have a grinding spread scenario, you can invest in that scenario, when there are imbalances between supply and demand. We expect to be able to invest capital and better returns there. None of this precludes our ability to quickly put the money to work, should we believe the opportunity exists to really earn that total economic return over the long-term. So there's a lot of flexibility and upside here. Byron, I don't know if you wanted to add anything to that.
