Sure, so let me start with that one. Because I think there was some questions around maybe with their turnaround time suffered, and we didn't get the $25 fee that comes with some of the government payers couple the current pairs. And actually, not really, AWR in Q4 was absolutely similar to what has been in the previous quarters. And our turnaround time performance was outstanding. We did in January when the surge came, we did a little bit, we did have a little bit of a hit to our turnaround time. But obviously, that's all contemplated in the guidance that we just provided and it wasn't a huge amount. When you -- back to the early question, bonuses, and the bonuses, when we look at the bonuses, you know, most of it is really our 50,000 employees. So people think about bonuses, must be senior management. Most of the cost is really, we pay 3% bonus to even our wage workers. And then obviously, we have other staff members that you know, at higher targets. And every year we budget for what we call, one x whatever that target is. So for most of the people do 3%. And based on performance, and we feel we've had reasonable stretch performances, when we had historically, we have not paid significantly above 1x. And we've had a number of years where it's below 1x. But the COVID, unpredictability and the surge in revenues, enabled us to pay our employees significant bonuses, in 2020. And again, in 2021. And so if you look at, without getting too specific, and we've shared a number in the past, a $3 billion wage bill, that's gone up in the last couple of years as we've grown the company. So you can kind of as a floor, say 3%, obviously a little higher, because if people want a higher bonus, that's about 1x. And then, we're paying a bonus that's substantially higher than that, in 2021, like we did in 2020. The other thing is, we did pay out a $500 payment to the majority of our employees to compensate them for COVID expenses. In 2020, we adjusted it out of our adjusted earnings, because we were seeing COVID as temporal and extraordinary. But once you get to your second time doing it, even though I still think it's extraordinary, we just decided not to adjust it out. So we did have over a $20 million payment, late in the year, $500 to our wage employee and some of our lower compensated professionals as well. So those are a couple of things that would go away and not be repeated like somehow, we had another surprising COVID year in 2022 like we had in 2021
