Thank you. Our next question is from the line of Sam Kemp from Piper Jaffray. Your question, please.
Samuel James Kemp - Piper Jaffray & Co. (Broker): Hey, thanks for taking the question. And congrats on the quarter. Can you characterize any changes you've been seeing in the cohorts you've been acquiring over the past couple of quarters? And I know it's early for your TV campaign at this point, but are you seeing any impact to your historical cohorts? And then Mike, can you give us an update on the marketing spend by region please? Thanks.
Richard Williams - Chief Executive Officer & Director: So, I'll start Sam. Thanks for the question. There is no major changes to call out in the cohorts. We obviously track them very, very closely. It's a huge piece of our strategy to invest in customer growth, but we've also held ourselves to a high bar of ROI there. So, lots in those cohorts like hawks and so far, it's really steady as she goes, they're right in plan, they're right on target with our ROI thresholds in 12 months to 18 months payback, and our customer acquisition costs are right in range as well. So, they continue to track, but again, we're watching them closely, because we're making an investment over time. With a threshold to 12-month to 18-month range, we need to watch them over longer stretches of time. Our oldest cohorts since starting this are eight months old. So, while they're trending in a great spot, we have time between now and their full paybacks to watch. So, nothing major on that front. The only thing that I'll call out on our historical cohorts is really, if you look at spend per customer, I think we're really happy that spend per customer as it stable as it is. We're adding obviously a large volume of new customers. And as a trailing 12-month metric, there's an inherent drag on something like spend per customer, because we're adding millions of people who have only had literally handful of months to spend on the platform and to see that number is stable as it is, I think that's very, very encouraging for us. The relationship with that to television, I'd say has nothing to do with it. I mean, it's just TV, while we're excited about the early response in returns, we really launched that moving into June. So, it only had a couple of weeks of runtime in June, so I wouldn't have expected that to have any material impact in Q2, or either that frequency overall of the customer cohorts or our spend per customer. That's something that obviously we're hopeful that it does reengage existing or previous Groupon buyers and that puts us more top-of-mind with more, but I think we're going to need a couple of quarters of time and performance and messaging with those customers in order to see that kind of thing play out.
