Sure. So, I mean, it's an important question. We are obviously, in a very mature cycle. I went through the market economics for CRE right now and they -- when you say they can’t get better, they get better. And then they get better. So we're not seeing any weakness in the CRE industry however, just common senses says that we’re not at the end of cycles. So, we -- one of the things I do like is that if you look at the CoStar information revenue stream, it is -- a lot of that revenue is now coming from banks and major owners. And when you go into a cycle, banks stepped up. They're buying typically. They don't reduce it. So, that is a stabilizing influence. And we are -- we continue having gone through 2008. We continue to discourage salespeople putting a lot of energy into plant, water and companies, and moving companies, and other companies that evaporate in the cycle. And we put effort into major owners, banks, investors, who tend to have more demand in the cycle. Now, we operated Showcase and we can observe LoopNet in a cycle. And there's a little bit of counter cyclicality there, where when you've got $150 million, but that looses a tenant, you're willing to spend thousands a month to try to replace that vacancy. And what we hear from people who have operated the apartment business through cycles is that, this is actually the worst cycle to be in, right. These are so low and, well, they can increase people's budgets, go up for marketing apartments. That makes sense. You do in a cycle get complete bankruptcies. But then, that's quickly followed by someone picking up the asset with an unlimited marketing budget, which is a wonderful thing to see. The STR revenue, we believe is very resilient. The renewal rates there are shockingly high. So we think there's some resilience there. And it's a basic operating metric being used by the hotels between their -- from their sales manager, general manager to the flags, brands and investors. It's something that is a utility. And it's not something that they have the optionality to shut off in a down cycle, even if -- unless they just simply don't exist anymore. So, we've done well in past cycles. We don't -- I think, we drop -- CoStar's sales drop 3% in 2008, which is remarkable, given the scope of it. And I think we're pretty diversified and pretty resilient when the next one comes. And there's the offsetting thought, which is, when you go into a cycle, it's a wonderful time to buy really good companies at a big discount, which we really look forward to.
