So in terms of the sites TAC rate, a couple of things, we have discussed this previous -- on previous calls. We have expected the year-on-year growth in the TAC rate would begin to slow, starting in the second quarter last year and you saw that through the balance of 2018. And this quarter, the constant TAC rate versus last year reflects ongoing growth in mobile, but it also benefited from growth in YouTube, where the associated content and cost are included in other cost of sales, and so, that’s the most important thing to point to. The other is -- we have previously discussed is, TAC as a percentage of revenues is also affected by a number of other factors, such as changes in product mix, device mix, partner mix, et cetera. So I’d really point you to the first point there. And then, as it relates to Waymo, I guess, a couple of things. We continue to be most focused on the ride sharing business here. We are pleased with the expansion and the number of Waymo riders that we have added since the last quarter. But as we have talked about on prior calls, we do continue to pursue a number of other opportunities, long-haul trucking we have talked about, logistics, deliveries, personal use vehicles, last mile solutions for cities, and then probably more to your question, licensing our technology and we did announced in March that we are making one of our 3D-LiDAR sensors available to companies outside of the self-driving car service, beginning with robotics and physical security. In other words in, for warehouse use or for farming and our view was that, that can provide further operating leverage to our business. So we are actually looking at a number of different ways, but their primary focus continues to be on developing the ride hailing business.
