Sure, Stephen. On data, we use data in three or four different ways. As I said, we've got almost $215 billion of closed transaction data which is highly valuable. The first way to use it every day is in risk-decisioning. What has enabled eBay and PayPal to allow transactions on the web and now on mobile seamlessly, quickly, often cross-border, stranger to stranger, is the data and our ability to leverage that data to provide superior risk-decisioning, and it's what now enables PayPal to underwrite transactions no one else could, and it's what enables eBay to offer a money-back guarantee through the eBay Buyer Protection. Second area we're leveraging our data is credit. In particular, PayPal has been combining BML's traditional credit storing mechanisms with the PayPal data, and that's fueling BML's ability to grow in transactional credit with superior loss performance. So again, we're using it to extend BML's reach. We're also using both eBay and PayPal merchant data together to begin experimenting, extending small merchant credit with PayPal. So, again it's an example where we have more data about a given merchant especially that happens to be an eBay seller, so we can more easily extend credit confidently, seamlessly and conveniently. Third area is marketing, and here I would say we're just beginning to scratch the surface as we do simple things like cross-selling, when we know a PayPal user that hasn't recently transacted on eBay or we know someone's buying in certain categories and we can use our -- the category level detail we have on eBay to help promote a cross-category transaction on PayPal. So, in this era of big data we are leveraging our consumer data more and more as we go. Then last area where we use the data is in our customer support. When people have a problem, they have a concern; we can take a holistic view of the customer when they contact one of our CS teammates around the world. So, the data has been an important part traditionally, I would say in risk-decisioning and it's growing in its importance in credit, marketing and the customer experience. With respect to the rewards program, we've taken a philosophy that we want to enable other's rewards programs, so that if someone's got a credit card rewards programs or debit card or increasingly merchant rewards and loyalty programs, they'd be able to be integrated into the PayPal wallet. So rather than creating confusion with our own rewards program, what we're doing is taking that same money we could invest in our rewards program and investing it in technology, investing it in lower take rates to enable others to provide rewards and we think that's the better way to get PayPal's ubiquitous extension across the web, mobile and over time offline.
