Yes. Well, first off, I would tell you that I think there are a couple of big regulatory trends. And on both fronts, we are way out in front, I really like our position. And it's funny, I mean, some of the companies that you mentioned, whether it's the walled gardens or I think there's now a case study of how we performed on mobile apps and on Safari inventory live on our website. All these companies work with us. And it's because we built everything around consumer transparency and choice. If you have the consumer's consent and they have visibility into what's being done, then you generate much better marketing returns. If you don't, then you have to fall back to an alternative form of targeting, oftentimes contextual and they just don't perform nearly as effectively. What's interesting is if you look at the best contextual targeting and then you layer in addressability on the top of it, it becomes significantly better yet again. So there's a real place for addressability as new forms of targeting start to emerge. Now, I'd also say that there's been a real -- some negative news recently about some forms of targeting and they're all forms that we don't do because, again, everything we do relies on consumer consent. But anything that is a device ID or relies on fingerprinting or some kind of technology that allows you to build an identity without necessarily knowing the identity and obtaining consent, we think those are losers. And those are -- there's no place in the industry for that. The other big mega trend that we're seeing, Tim which has gotten some news recently is we've long been out front of the market and talked about the fact that we're neutral. We'll work with anyone and everyone who's ethical, including companies that have called themselves our competitors. We are interoperable; and I think you're seeing a trend now in regulation towards mandating the very kind of interoperability that we've long reached. And again, that's going to help us a lot, whether it be with the cloud providers, where we're increasingly working with many of them. It's not necessarily in our forecast but we think it's some nice upside as we scale that, whether it's with the thousands of publishers that we work with, whether it's the walled gardens, whether it's the CDPs, whether it's the marketing cloud, we'll continue to be interoperable because what we bring is so unique. What we bring isn't a clean room, isn't a CDP. What we bring is data access, identity, data activation and all the permission controls. And those capabilities are things that are best done at scale, neutrally and interoperably for the entire industry which is exactly our strategy.
