Yes, sure. No problem, Catie. So the net carrying value of $3.1 billion and you can see this on Slide 6 that I went through, but that incorporates the net book value of the assets, maintenance rights asset and other things, lease premium assets that I mentioned. And it also incorporates the maintenance reserves of roughly $700 million. So those are the reserves that we got for it. And then in addition to that, we've got that $260 million of letters of credit, which are also protections that we have, and we're drawing on them, but we don't put them on our balance sheet because it's not a cash reserve that we hold, it's just a letter of credit that we can draw on. And so if you -- the way I would look at it is, I'd say, take that $3.1 billion carrying value, subtract the amounts of letters of credit that we've received to date, and we expect to continue to get these, and then subtract the carrying value of the aircraft that we've removed from Russia, so roughly $400 million and that gets you to around $2.5 billion. So that's what I would look at as the net exposure there. And in terms -- and I guess maybe just to frame it, in terms of what does that mean for us, right? So if we had to write down that entire amount, let's just say we had to write down that entire amount in the first quarter, the impact on us would likely be to take our leverage ratio up to about three to one, right? So obviously, that's a setback from where we were today, which is just under 2.7 to 1. But we have to keep in mind it is about 5% of the fleet or a little under given those offsets. And so, we would expect to de-lever during the course of the year back towards our target level of 2.7 to 1. So I think that from that standpoint, while as I said a setback, it's a manageable one and the overall trajectory of the business isn't really affected. I should say also because we have gotten some questions in terms of financial covenants, that's really unimpacted as well, well below any thresholds on that front. So now, in terms of the insurance recoveries, so let's say, if you had to take that, if we took that write-down during the first quarter, then any insurance recoveries coming in would just come in as other income. So it's not necessarily a gain. It's just other income that you would be recognizing, when you receive it or when it's probable or receive.
