Thank you very much, Vasant. An official public welcome from all of us. First of all, let me start with commenting that we're very pleased with the quarterly results. We think of them as solid and consistent and certainly gratifying in the face of some of the more challenging economic conditions and geopolitical concerns that we see around the world. Net revenue grew 9% nominally. FX impact hurt growth by two and a half points. Operating income growth of 11%, payments volume increased 11% on a constant dollar basis and cross-border volume growing at 8% on constant dollar basis, are all very solid numbers. We see very little change in the overall global economy, with some exceptions and we see more short-term risk than we see up side. Consumer spend in the U.S. specifically continues at reasonable levels but is not accelerating. Gasoline prices continue to negatively impact both credit and debit. Outside the U.S., we see continued weakness in Russia and Brazil, but we do see strength in China and our Middle East and North Africa region. And the effect of the strong U.S. dollar, as Vasant pointed out, is meaningful. We see this through the FX translation impact, but additionally, the benefit of that we see of U.S. spenders outside of the U.S. is outweighed by the negative impact on the non-U.S. spenders spending less in the United States. Away from the economic growth environment, we continue to feel terrific about our activities to drive growth which I will talk more about. We continue to make excellent progress on our evolving technology initiatives which include everything we're doing in the digital space, mobile specifically, Visa Checkout and the work we're doing in our global merchant services and solutions groups. We continue to have a strong flow of significant client wins and renewals. I will speak a little more on several of these points in a moment, but in sum, while we remain appropriately cautious in the short-term, we remain quite bullish on the medium to long term and continue to believe there are tremendous opportunities for years to come. Let me just amplify some of the comments that Vasant made regarding payment volume for a second. First, the negative impact of gasoline on our U.S. payment volume is significant, at three percentage points. Though the initial impact on payment volumes was felt in our first quarter, the full impact did not hit until the second quarter and so the revenue impact will not be fully felt until our third quarter, because of the quarter lag on service revenues. In an update to our March quarter, Visa Insight Survey, things haven't changed much with consumers. About 30% tell us they're spending more in other categories, up from 25% last quarter. The two categories that continue to stand out are the lower ticket categories, groceries and quick service restaurants. As I said last quarter, the lag time between lower prices and spending we think is about six to nine months, as consumers accumulate enough to feel comfortable making larger purchases. Keep in mind, consumer confidence and confidence in sustained lower gas prices will impact their willingness to spend. Cross-border volume remains steady at 8% in the quarter, as we said. And as I have mentioned and Vasant mentioned, the effect of the strong U.S. dollar against certain global currencies is negatively influencing cross-border spend and ultimately revenue growth. The U.S. cardholders are spending more outside the U.S. as a result of the stronger dollar, resulting in higher transaction and payment volume growth on a constant dollar basis at international merchants. However, given currency translations and generally lower acquiring fees in foreign countries, that volume is not as lucrative as what we would have enjoyed on an inbound basis. The strengthening of the U.S. dollar has hurt in-bound spend to the U.S., primarily from the Canadian, European, Brazilian and Japanese corridors. As Vasant mentioned, higher currency volatility has offset some of this. Let me just turn now and talk about some important client activity. Starting with the U.S., we renewed a multi-year credit issue agreement with U.S. Bank, a great partner and one of our leading issuers and the fifth largest commercial bank in the United States. U.S. bank has been a long time Visa partner and we lack further to building further upon the exciting things we've done with them, in terms of innovation, new product development and security. In the U.S. co-brand space, Best Buy, the world's largest retailer, will convert their consumer credit card portfolio to Visa later this summer. We also renewed a multi-year credit agreement with BP. BP has been a longtime Visa partner and launched its first co-brand in 2006. We're thrilled with our new agreement with Costco. We're very pleased to have been selected to replace American Express as the credit card network for its U.S. warehouse clubs and gasoline locations, beginning April 2016. A strategic benefit for all Visa issuers and their cardholders. We're also excited to be partnering with Citi on the new Costco Visa co-brand credit card. We view Costco as truly unique opportunity and very strategic. As I said, it is good for Visa, but an even bigger benefit for all of our clients. They're one of the largest and best retailers in the world. The third largest merchant in the U.S. according to the national retail federation, someone who historically did not accept our credit product and we now have an opportunity to gain acceptance where MasterCard and American Express are not accepted in the credit space. We also love that this is a truly long term acceptant [Technical Difficulty] and co-brand partnership. For all of our clients and their consumer and business clients, it will be the first time in 16 years they gain access to the tens and tens of billions of dollars of annual credit payments volume that heretofore went to American Express. It is a great opportunity to drive incremental usage. It should help all Visa issuers drive their cards towards the top of the wallet and increase new account and card holder acquisition opportunities. This was a very competitive process and there has been much discussion of what drove the outcome here. I don't want to speak for Costco, but let me say that I have not met a retailer that cares more for their clients, their members more. Going forward, Costco will be entrusting their clients, their members, these precious relationships to Visa. If it were me, money wouldn't win the day. The best brand with the best capabilities would win. I've consistently said price matters, but cannot win the strategic relationship. So our strategy is not to be the low-cost provider. As I think about what drove the decision here, I look at a series of things, including a view that we're the premier brand for Costco members, the belief that our brand will help Costco grow more than all the others, clear, strong brand preference among their members and target market, specifically with the higher growth affluent and millennial holders which in this case will drive membership and sales growth directly for Costco. Our broad global acceptance, our superior data and analytics capabilities and our leadership on innovation. I would also point out that we feel that all the benefits I've outlined, plus what our issuers bring to the table, can create more value than others. Specifically and quite simply, we, our issuing partner and the co-brand can make more and provide greater value to our clients than smaller, closed loop networks. As a remainder, the implementation of these agreements is subject to the purchase of the existing co-brand credit portfolio by Citi. Turning to our business outside the U.S., let me first start with China. Before I turn to market opening which I know is a topic that you all want to hear about, I want to talk for a second about our existing business. It is doing extremely well. We have a significant and fast growing business, with relationships that have been growing and deepening. We're the market share leader versus non-Chinese providers and that share has been steady since 2013. We continue to sign contracts and be awarded new issuant business from Chinese Banks. As examples, this quarter we renewed and expanded our agreement with China Civic Bank, one of the largest partners in China. The program will now include issuance of Visa only branded companion cards, in addition to the dual branded program in place. China Everbright Bank, one of China's largest financial institutions renewed their credit agreement with Vise. Regarding the market opening news, clearly this is a significant and positive step. The facts as we've read them thus far are consistent with our expectations and we're very excited to see more specifics which obviously will be important. We do intend to apply for a license. As I've said, we have a strong business today with great local relationships which have only become stronger over the past several years. We're excited to participate in one of the most important markets in the world. And for Visa to help in the growth of domestic Chinese marketplace, working with Chinese companies and the Chinese government. To be clear, we're not pursuing this for the short-term profit opportunity. This is a long term commitment which will pay off over the long term. We intend to prove our value as a partner within China, so bringing our value added capabilities to help grow the Chinese economy will come before our revenue and profit growth for quite some time. Regardless of when we start to participate domestically in China, we do not expect this to be a meaningful contributor to our financial results for many years to come. Turning away from China, First-Ran Bank, a large issue in South Africa and our largest issuer in sub-Saharan Africa, extended their contract with Visa. We also renewed our partnership with Desjardins, the leading financial group in Canada and the fourth largest cooperative financial group in the world and lastly Banorte, one of Mexico's oldest and largest national institutions, renewed their credit agreement with Visa. On the other side of the equation, Citibank and Itau will be moving their business away from Visa. In certain regions around the world, we have contacts with Citi which will continue to run for quite some time. In terms of how quickly these conversions commence and ultimately how long it takes has not been made clear to us and we will let you know as we learn more. While losing any business is disappointing to us, we know that we're not going to win everything, as we operate in a very competitive environment. We've always been very thoughtful and strategic about choosing for which clients we want to be aggressive in this competitive process and we feel great about our portfolio of client relationships. Importantly to us, we remain disciplined in our approach to negotiations and the net of these recent wins and losses leaves Visa and our partners in a better strategic position for the long term than would have otherwise been the case. A couple of other quick updates on the regulatory and legal fronts. First of all, in Russia, we have been actively working with the national payment card system and central bank to achieve full migration of Russian domestic Visa transactions with minimal disruptions. All domestic Visa transactions will continue to be processed in accordance with the national payment system law. And in the U.S., on the merchant litigation case, we continue to make good progress in settling the opt-out cases. Fiscal year to date, we've paid out $321 million and additional settlements are progressing nicely. And we continue to lead the world to the world of digital commerce. Visa Checkout continues to make great strides. We now have 260 financial institution partners and 140 merchants live globally. To date we have over 4 million registered users, over $46 billion in total addressable volume accepts Visa Checkout and we continue to add merchants, including small and medium size retailers, where our acquiring partners are helping us grow acceptance. We're also deploying Visa Checkout outside of the U.S.. As an example, we launched Visa checkout in China at the end of March, China Merchant Bank is the first institution in China to introduce Visa checkout to its customers. In the coming months, we're working with other Chinese institutions to deploy checkout. In April, we kicked off consumer marketing campaigns in both Australia and Canada, in partnership with some of the biggest merchants in those regions. We're on track to be live in a total of 16 markets this year. ComScore conducted a study last month to evaluate our progress with merchants since launching Visa Checkout last July. The findings are very clear. Visa Checkout customers convert to buyers 69% of the time. This is 66% higher than conversion rates reported with traditional on-line checkout. The product is doing exactly what we said it would do, solving the on-line friction problem at a rate that's higher than the competitive solutions we surveyed. In the digital solutions space, a few comments. In my time here at Visa, it is amazing the amount of companies that are working and talking about the future of payments in the role, some very young, some very established. Regardless of tenure, it's clear to me that they fall to two categories. Those that talk about being innovative and those that are actually driving innovation in way that truly drives incremental value and can scale. I'm proud of the work of the Visa team and proud to be leading the industry into this digital world. When we launched tokenization, we told you it was more than a set of just security standards. We said it was a platform to enable new commerce experiences, then came Apple Pay. When we participated in the Apple Pay launch, we said it was just the beginning and there would be more solutions that leverage our digital platforms. Since then, Samsung has announced the new Galaxy S6 payments experience and Google's Android operating system supporting host card emulation. And we have several clients developing new HCE based applications in our sandbox as we speak. As the industry leader, a Visa partnership gives the chance for these experiences to be successful because of our technology, our scale and our leadership. Our innovation is not something every consumer sees, but it is the things that we do as a platform that others can build upon and it is our platform that becomes embedded in all sorts of devices, operating systems and mobile apps. Essentially we're enabling our partners to take advantage of one common payment platform and set of standards, but still able to customize their solutions to their specific client needs appropriate to their markets, with their preferred user experiences. Great companies come to Visa first because they know we understand the technology of payments better than anyone else and we understand the needs of their users. And we continue to build out our capabilities to support our merchant partners. We completed our acquisition of TrialPay this quarter. It is a platform that we've worked with before and one that proved its value proposition before we decided to acquire the company. Combined with our broader merchant capabilities across Visa Analytics, Loyalty Products and VisaNet capabilities, this is a platform that we intend to use to help merchants improve their marketing and thereby drive their incremental sales. During the last six months, we introduced to the market three new products and solutions specifically designed to help our merchant partners. First, we created a customer intelligence dashboard, a custom analytic dashboard for merchants to enable them to understand who is shopping with them at the store level. We're helping merchants not only understand the sales trends, but also who is shopping, their demographics, where they live, where else they shop, et cetera. The platform is helping our gasoline merchants better predict demand, airlines to optimize routes and load factors and many others to optimize marketing campaigns. The second solution is a digital marketing measurement product. Earlier this year, we launched a new platform which enables our merchant clients to measure their digital market spend with an entirely new level of accuracy. When a merchant runs a digital campaign, we're able to show them in real time how many of those impressions led to specific sales using a Visa card. For many years merchants have taken a big leap of faith that clicks led to real sales. For the first time ever, we're now helping them measure the actual sales. The final example is a pilot program but one that we're excited about. Platform that actually drives new customers into our client's store. The platform is powered by Trial Pay, where we place targeted merchant offers on the web and on mobile apps. For example, you're checking into a flight, you will see an offer to get 500 miles if you shop at Pete's coffee in the next week. When the customer comes in to buy their coffee, they're notified in real time that they've received their bonus. Miles, in this case. Also we track the purchases and show the merchant in real time how many of the customers are coming into which specific stores. Early days, but client interest remains very strong. As you can see, these are products which we believe over a period of time changes our dialogue with merchants as we help them grow their business. So just to wrap up, we're very pleased with our performance for the first half of the fiscal year, especially in light of some of the challenging aspects of the economic environment. It continues to be a very exciting time in payments, as you can tell from all the recent announcements. We remain bullish on our future and we continue to broaden and deepen our work relationships with issuers, acquirers, merchants, governments and other third parties. With that, Vasant and I will be pleased to take your questions.
