Yes. So I mean I'm not going to really rephrase that as an impairment that Ken's said. I mean so, you know, these models are trying to predict, you know, human behavior where lot of things go with the human behavior that aren't necessarily picked out in these models. And I think in particular what you had in the first quarter or second quarter coming in, if you had to converse substantial volatility in the tenure. So everyone thought, oh gosh, you know, we missed the bottom of the rates. And so that actually, based on the models, it shouldn't see a slowdown in prepayment behavior because rates are higher. But no, that's not what happened, here the acceleration of prepayment behavior, and to me, my closest analogy is it's like last call, it's like, you know what it's 2:00 a.m., you got to get in here otherwise you're going to miss out on the lowest rates, you know what in generation. But then what happened, while, we thought that, you know the tenure get up to 190 and now we're back to, you know, ones in the 130 range. And so we're getting now with even an echo wave of that, so these prepayment speeds, you know, have come in higher than we thought, that resulted in, you know accelerated amortization, I'm not going to necessarily call these impairments, but getting to your point, a more normalized level, we would be looking for about a $10 million quarterly positive in that servicing line. You can't just say, oh gosh, it's under by 30 million on a run rate basis though because of kind of common adjust made in terms of, you know, the gain on sale number is better, probably because the servicing revenue was impaired, servicing revenue being impaired, means there's a lot of refi business going on, there's a lot more activity generating in the system. And so the cost opportunity, gain on sale opportunity is a bit higher. So it's not kind of a one for one deal, but yeah on, you know a steady state, we'd look for about a plus 10 in that, I mean it's, you know, it's in the revenue, it's a contra-revenue for a reason because it's not supposed to be a contra.
