Yes. Well, first of all, I would say it's early days and hope -- well, hopefully, it's late days, and this will all be behind us very soon. But it is early days. But if you look back to SARS, if you look back to other issues of this type in the marketplace, what you tend to see is there's a lot of noise in the market during that moment in time and you can see in areas that are particularly affected. Let's look at Hong Kong, at the moment, our transaction activity in Hong Kong was down in the fourth quarter. That doesn't surprise us, both with the protest and then with the issue with the coronavirus. But what you always see in these situations that we would expect to see here is a strong snap back when the issue goes away.
And so unlike some other economic drivers that are, I think, more structural, we would expect that what you lose, if you lose activity during the issue, that activity comes back, incremental to normal activity in the subsequent quarters. So at the moment, I wouldn't say we're sanguine, we're not. There's a lot of work we're doing right now to make sure our employees are safe and well taken care of and our clients are well taken care of. But we are not seeing, other than in Hong Kong, and I think that's both, as I mentioned, the protest and the coronavirus, we're not seeing any impact on activity right now.
I would also say that our business is one where transactions are worked on for a very long time, both in the leasing and in the capital markets space. People don't tend to stop those transactions over issues like this. They would -- people will slow down transactions in a real economic decline. So what we watch for is really the impact on GDP, and that is unknown at the moment. If this has -- if coronavirus has a material, sustained impact on GDP, we're going to see a slowdown in transaction activity. At the moment, that is not what's being forecast into the marketplace.
