Yeah, thank you for your question, Mark. Let’s take them in row. First on the apps revenue recognition policy, let me explain what happened there, and I’ll use it with an example if you don’t mind. If you – and the way we did it is, we changed the revenue recognition. So if you say, you buy an app for $1 on the PlayStore, $0.70 of that dollar will be paid to the developer and does not impact on P&L, it didn’t before and it still doesn’t today. So that hasn’t changed. In the past though, we would have booked the remaining $0.30 on a net of payments to carriers and OEM and then booked that as gross revenue. Beginning in Q1, however, the entire $0.30 is now booked as gross and the payments for the carriers and the OEMs are now booked on other cost of revenue. So that’s the big change that has happened and basically the reason why we did this is as part, we were looking to the second half of 2012, we were seeing these used to be kind of immaterial numbers for us. And then when we saw through the second half of 2012, we decided to kind of tune our accounting policies and made that change in Q1. So that’s the issue what’s going on the revenue recognition. So you’ll see the impact both on gross and then as I said on other cost of revenue and then you get the net. So on a net basis, it doesn't change. On the TAC issue that you’ve raised, Mark, the answer is pretty simple, right? If TAC is dropped overall, because of the change in our ad policies that we’ve done through Q4 and Q1, so in pushing hard on implementation of our ad policies to the benefit of the user, the impact of that is actually that it lowered our network revenue, but it also lowered our TAC, which is tied to AdSense partners in that role. On Google sites, you have noticed that it continues to grow, and it grows because of mobile growth. So the volume of mobile in our mix is driving TAC to go up. So, overall TAC is down for the quarter as an aggregate basis. The ad policy changes have driven them down and then our mobile for our own sites continue to drive them up. But that’s a good story because it means mobile has really continued to be on fire. So that’s the pieces of the puzzle. Thanks for your questions because it wasn’t that easy to understand at first. But I hope that clarifies the point. Thank you, Mark. Sean, to our next question please?
