Sure. I think Tom, what we've disclosed in the past is, if you look at the guarantee fees, it tends to run broad range 2.5 billion or so a year in terms of the guarantee fees we collect. It's very much dependent on terms of the market on how much of that we're spending. I think as we look at last year you could expect, we spent less than that because it was a very low [vol] year. And that came through in capital formation. We're part way through the quarter. So it's really too early to say exactly what's going on for this quarter, other than hedging costs would be up. Again probably no big surprise there, but with the [vix] running around 30, you can expect that we would have increased hedging costs, whether it's above the fees or not, or at or above or wherever. I'm not, not exactly sure at the moment. For the gain, because we haven't -- we don't have a quarter fully done yet, but I think it's very much within, as Marcia mentioned within the range of what we've seen historically. So we would expect to have that kind of performance, like we've seen historically. With respect to the interactions of how things are going. I think, you'd see the benefits from higher rates again, it's mentioned that there is good offset there. The quarter-to-date, as we're talking about you're kind of rebalancing hedges. We do have, as you mentioned, shorter dated hedges. So, we are subject to roll -- kind of the roll cost of those and are experiencing higher premiums that we'd have to pay for options bought. But I would also just keep in mind that a good chunk of our hedging book is off of futures. So, in some respects, as interest rates start moving up on the short end futures carry will start to reduce somewhat. So that'll be a little bit of tailwind eventually once the fed starts raising rates. And I think, the other thing I'd mentioned is just that, keep in mind, since we are -- our focus historically is been a on more instantaneous chops and risk limits that way, as opposed to an immunization strategy of GAAP earnings. We don't tend to be as responsive to the market maybe as some others might be. So as we see a lot of chop in the market, we're not rebalancing hedges maybe as quickly or as just kind of a immediate reaction as you might have to, if we operated a different way. So that does mitigate a little bit of the cost because we're not getting whip saw as much as you might otherwise get.
