And Sterling, this is Jim. I would just add to that, you know, there's always a baseline funding that we make available and increase just simply because a huge aspect of what we do is cybersecurity, which is very difficult to predict. The threat environment is constantly evolving. It's generally always intensifying and increasing. And so, there are constant investments we make in training, education, new hires, people, technology, hardening our infrastructure and proving its resiliency that are ongoing. In addition, there are responses that we have to make to new threats that are anticipated. These just are routine and happen all the time, but the precise nature, the precise response, and therefore the price – the precise budgetary aspect of the response is difficult to predict. What you're seeing is our best estimates based on a long history of experience of doing these kinds of things. In addition, we fund research and that research evolves. And we recently identified, for example, a huge number of queries that were coming into the root servers, a massive spike in queries that were literally the result of unintentional activities, with a browser behavior that we were able to actually highlight point out, and help rectify, and eliminate a huge amount of volume that was that was hitting [indiscernible] root servers. There's quite a bit of this research that we do and publish, we've done work and name collisions. We do a lot of good instrumentation that helps manage and improve performance and security across the net. We identified domains that are the source of [botnets], and other sorts of cyber attacks. We share those with different companies, government agencies. So the teams that are working on that are always evolving, growing training, hiring additional folks. That's our primary mission. We address it many Broadway's, but it's our top priority. So, it shouldn't be a surprise. There are times, you're going to see increased spending on it. It's just the nature of the business that we're in. And that's our expertise. And that's our mission.
