All right. Good afternoon, everyone, and thanks for joining. Q2 marked another strong quarter for Airbnb. We had 125 million nights and experiences booked. Revenue increased 11% year-over-year to $2.75 billion. Net income was $555 million representing a net income margin of 20% and we generated $1 billion of free cash flow. Our total trailing 12 month free cash flow was $4.3 billion, our highest ever, and our strong cash flow allowed us to repurchase $749 million of our shares in the quarter. And as of the end of Q2, we had $5.25 billion remaining on our share repurchase authorization program. Now during Q2, we continue to make progress on our three strategic priorities, which again are making hosting mainstream, perfecting our core service and expanding beyond the core. So I’ll share a few highlights on each. First, we are making hosting mainstream. Last year, we shared a commitment to make hosting just as popular as travelling in Airbnb. We've been focused on raising awareness around the benefits of hosting and providing better tools for hosts. In Q2, we surpassed 8 million active listings driven by continued growth across all regions and market types. We're not just growing supply and we're also committed to ensuring that it's high quality supply. Since launching our updated host quality system last April, we’ve removed over 200,000 listings that failed to meet our guests expectations. And we'll continue to raise the overall quality of listings on Airbnb so we can consistently deliver high quality stays. Second, we're perfecting our core service. We remain focused on making Airbnb more reliable, affordable and a overall better service for hosting guests. We’ve rolled out hundreds of new features and upgrades over the past two years to do this. This includes launching major reliability initiatives like guest favorites which make it easy for guests to find the best listings in Airbnb. Now since launch, last November, we've seen over a 150 million nights booked at guest favorite listings. We've also made dozens of smaller changes that have led to improved usability and booking conversion. These include things like simplified set up and login, improved map, clear cancellation policies and so much more. Now we've made tremendous progress and we'll never stop improving Airbnb. We're going to continue this commitment. And finally, perhaps most excitingly, we are expanding beyond our core. We continue to drive growth by investing in underpenetrated markets. In Q2, growth of gross nights booked on an origin basis in our expansion markets significantly outperformed our core markets on average. Our core markets again are US, UK, France, Australia and Canada. This is largely due to the success of our global expansion playbook which includes a more localized product and marketing approach. We're also expanding Airbnb’s brand positioning beyond travel accommodations with the launch and roll out of Airbnb Icons which is a new category of extraordinary experiences that we launched in May. Now since launch, we see nearly 40 million views of Icons on our site. Helping people understand that Airbnb offers more than accommodations will be critical as we expand our offerings in the coming years. Now, looking back to Q2, we saw a number of positive business highlights. First, guests are increasingly booking on the Airbnb app. We've continued to optimized our mobile website’s app downloads and we believe our approach is working. Nights booked in our app during Q2 increased 19% year-over-year. Now these bookings now comprise 55% of total nights booked and this is up from 50% in the prior year period. Now in addition to our success of mobile downloads and bookings, we're continuing to see growth of first-time bookers on our platform with the highest levels of growth seen in the youngest age demographic. Second, Airbnb is uniquely positioned for special events where continuously more guests choose Airbnb for major holidays and events. The week of July 4th for example represented our single highest week of revenue ever in North America and we saw similar trends in Europe. Now in anticipation of the Olympics which is in Paris, nights booked in Paris through Q2 were more than double what they were this time last year. Additionally, cities hosting matches during the recent Euro Cup in Germany saw an average of more than 20% year-over-year increase in nights booked. And supply has increased to meet the higher demand. So we have 37% increase in active listings in Paris in Q2 compared to the year ago. And these events, what they really do is they highlight Airbnb’s unique ability to disperse travel and spread economic benefits by allowing people stay in local neighborhoods where there are no hotels. Finally, supply growth is improving on Airbnb. We made huge strides for supply growth, we remain just as focus on supply quality. As we improve quality, we believe more people will try Airbnb unlocking even more growth. We have two major initiatives underway to help us do this. First, we're removing low quality supply. As I shared earlier, we've removed over 200,000 listings since April of last year. Second, we're making it easier for guests to find the best stays on Airbnb. We launched guest favorites as well as top listing highlights, which show the top 1%, 5% and 10% of eligible homes on Airbnb. These new features make it easy for guests to find the highest quality homes on Airbnb. In Q2, we also saw active listing managed by Superhosts, some of our highest quality hosts, increase 26% year-over-year. We're proud of our Q2 results. Now, turning to Q3, we're looking forward to another record summer travel season. We're encouraged by the excitement around the Olympics and the Euro Cup and we're also encouraged by the relative strength of Latin America and Asia Pacific which continue to be our fastest growing regions. However, we are seeing shorter looking lead times globally and some signs of slowing demand from US guests and our Q3 outlook incorporate these recent trends. We are watching these trends closely along with the impact any macroeconomic pressures might be causing. And we're continuing to execute against our growth strategy by improving our service, expanding in less penetrated markets and introducing new offerings. We believe this growth strategy will over the long term offset any transitory macro trends. So with that, Ellie and I look forward to answering your questions.
