Okay, thanks. So I just want to add a couple of things to that Smedes, sorry. First of all I think Joan might have cited just now 26% of the hotels are closed, it's actually 26 hotels that are closed not 26% just to be clear about that. But the only other thing I would add is, we are operating in the same market that everyone else is. I think the key issue that we're focused on right now is how our teams are responding and how we can proactively engage and manage this situation. And I can tell you that we've come into 2020 with great momentum. We had significant share gains in the fourth quarter in China, the top five markets, which for us in China include Shanghai, Beijing, Shenzen, Guangzhou and Hangzhou, we were up almost six points of market share in the fourth quarter. If you look at China, excluding -- Greater China excluding Hong Kong, Macau and Taiwan, we were up almost four points in market share. And even including Hong Kong, Macau, which had a structural headwind for us, because of our casino room block, we were up, over two points of market share over 200 basis points. So, we've come into this year with tremendous momentum, in our relative performance. And in fact the first two weeks of January, were quite strong, throughout China. So, I guess what I would tell you is, yes we're going to focus on, how we can mitigate the impacts and so forth. The fact is we live in the market along with everyone else. And I think the key for us is, maintaining that the strength of our relationships, and the strength of our performance on a relative basis. And that's what, I think, you'll see from us, this year.
