Sure. So I know we tend not to continue to reiterate the point but when you look at premium this quarter, in General Insurance, you have to keep in mind that we're comparing those the first quarter of 2020, where there were still growth in those premiums, and it was pre-pandemic. So with the premiums fell commensurately with the reduction and exposures in the three quarters of 2020 as well as the first quarter of 2021. But we stopped we -- it but it bottomed out in the third and fourth quarters and start started to come back in the first quarter. So our view is that as the economy rebounds and reopens that exposure unit, particularly and workers compensation will increase fairly rapidly. And, like I say, once we get out into the second, third and fourth quarters and we're comparing those to 2020quarters, those premium levels, I think will be will be greater, perhaps significantly greater. So we are seeing exposure return, as I say their workers compensation exposures bottomed out in the third or fourth quarter, what we saw in auto exposures were a drop off in the second quarter of 2020. And then, and then things have picked up in in auto exposures in the rest of last year, and again this quarter. So, exposures are definitely coming back, we would expect them to come back in a much more robust way, as we move throughout the year, and the economy continues to, to improve. So, right now, it's a mixed bag, Greg, but the, what you're seeing in that, that increase is, is just the effects of coming off a reduced exposure base from 2020. And rebuilding that exposure base as we go forward. And then of course, you're getting, you're also getting lift from rate, but the exposure base is going to have much more of a contribution, the exposure base increase is going to have much more of a contribution to top line as we go through 2021 after the first quarter.
