Thanks, Yanjun. Hello everyone and thank you as always for joining today's call. I'm really pleased to report that we had another great quarter. Across the business we saw sustained strong growth and further improvement on the top and bottom lines. For Sea as a whole, our adjusted revenue tripled year-on-year to reach $665.4 million and our adjusted EBITDA improved once again to negative $11 million. Our results for the quarter show that we continued to drive revenue growth and improved efficiencies across our business. We're increasingly able to fuel our growth with cash generated through operations which we believe positions us well to continue driving long-term sustainable growth. As you know at the start of the year we set ourselves some very ambitious targets for adjusted revenue growth in 2019. With our very strong performance in the first half of the year, we have decided to raise our guidance for our full year adjusted revenue for both digital entertainment and e-commerce. For digital entertainment, we now expect full year 2019 adjusted revenue to be between $1.6 billion and $1.7 billion, representing 142.0% to 157.2% growth from 2018. This compares to the previous guidance of between $1.2 billion and $1.3 billion, representing 81.5% to 96.7% year-on-year growth. We are also increasing our guidance for full year adjusted revenue for e-commerce to between $780 million and $820 million [ph] which represents 168.3% to 182.1% growth from 2018. This compares to the previously stated guidance of between $630 million and $660 million, representing 116.7% to 127.0% year-on-year growth. Our increased full year targets reflect our confidence in both the growth opportunities ahead and in our ability to execute our strategies to capture those opportunities. Let me start with Garena where we saw healthy growth across key metrics in the second quarter. On the topline adjusted revenue for the digital entertainment business more than tripled year-on-year to $443.2 million. In terms of the bottom-line adjusted EBITDA for digital entertainment was up 443% year-on-year to $263.8 million. Adjusted EBITDA margins further increased to 59.5% for the second quarter of 2019 from 34.9% for the second quarter of 2018. Our quarterly active user numbers, or QAU, almost doubled from a year ago to reach more than 310.5 million. The paid user ratio which quarterly -- which is quarterly paying users as a percentage of QAUs more than doubled from 4.1% a year ago to 8.4% in the second quarter. There are three key highlights to Garena's success this quarter. First, we continued to drive strong organic growth in active users globally. In particular, Free Fire, our self-developed smash hit game was the third most downloaded mobile game and the most downloaded battle royale game globally across the Google Play and the iOS App Store in the second quarter according to App Annie. We are excited to see continued user growth across our core markets of Southeast Asia and Latin America as well as in other growth markets like India, Russia, Turkey, and the Middle East. Second, we are strengthening our foothold in Latin America. As we mentioned in previous quarters, the huge success of Free Fire in Latin America is opening up opportunities for Garena in this high-growth market of more than 600 million people. I'm pleased to report that in late July, we launched the Garena Speed Drifters across Latin America. This is the first third-party licensed game that we are publishing in Latin America and it is an important step forward in expanding our footprint in this very exciting market. Finally, we continue to deepen our engagement with our gamers, while driving monetization across our game portfolio. For example throughout June, we ran a series of themed competition in Free Fire and offered a wide range of in-game items based on campaign themes, which were very popular with our gamers. This translated into both user number and revenue growth for the game. At the same time our esports and community building efforts are also enhancing engagement across our titles. In Brazil, for example, we hosted our largest ever esports tournament for Free Fire in that market in July which attracted over 12 million views online. During the grand final of the tournament, the peak on current views on YouTube alone exceeded 800,000. In June and July, we also hosted Arena of Valor World Championship in Vietnam. This was the first time that this global tournament was held in Southeast Asia and it was a huge success. We recorded cumulative online views of over 74 million with over 850,000 concurrent views at the peak. We believe that this showcases Arena of Valor’s popularity as one of the region’s top mobile MOBA games. Looking to the quarters ahead, our pipeline remains strong. For example, we recently launched pre-registration for Call of Duty: Mobile in our core markets in Southeast Asia. We also see plenty of headroom for our existing titles to continue growing. In particular, as we further deepen engagement with Free Fire’s growing global user base, we believe that this game and the battle royale genre in general are still young and evolving. For the upcoming quarters, we believe that Garena is in a great position for long-term growth. This is also reflected in our decision to raise the full year outlook for the digital entertainment business. Turning to Shopee. In the second quarter, we continued to deliver on our strategy to scale with efficiency to capture market share and deepen monetization. Looking first at growth, Shopee further strengthened its market leadership. In the second quarter, it ranked the highest in the Shopping category by both average monthly active users, and by app downloads across the Google Play and iOS App Stores, in both Southeast Asia and Taiwan, and ranked the third in app downloads in the same category globally, according to App Annie. Gross orders for the quarter increased more than 90% year-on-year to 246.3 million, and GMV for the quarter increased 72.3% year-on-year to $3.8 billion. These data points underline our success in building and sustaining a strong and engaged user base across the region and continuing to capture market share. As we scale, we also continue to improve on growth efficiency. Shopee’s adjusted EBITDA loss per order decreased by $0.46, or 31.3%, compared to the same period in 2018. More importantly, we continue to see sustained improvements in monetization and take rate and adjusted revenue more than tripled year-on-year to $177.4 million dollars. Adjusted revenue as a percentage of total GMV increased to 4.6% in the second quarter, up from 2.6% for the same period a year ago. And adjusted marketplace revenue as a percentage of total GMV reached 3.6% in the quarter. Indonesia, the biggest e-commerce market in Southeast Asia and also Shopee’s biggest market, our growth accelerated in the second quarter as we further extended our market leadership. We reached over 110 million orders for the quarter, which represents a daily average of over 1.2 million orders. In Taiwan, Shopee continued to record a positive quarterly adjusted EBITDA before allocation of the headquarters’ common expenses for the second quarter. This is a powerful demonstration of the long-term profit potential of our e-commerce model. Our focus for Shopee is not only on the quantity of growth, but also on quality. We believe that long-term success for Shopee is based on capturing the hearts and minds of shoppers in our region, and translating that into deep and sustained user engagement. That’s why one metric that we track closely is total time in app, which we believe is a measure of our ability to attract, and deepen engagement with our users. By this metric, Shopee was once again number one in the second quarter in Southeast Asia as a whole and in each of our five biggest markets on Android, according to App Annie. From the beginning, we designed the Shopee experience to be highly engaging and social, by pioneering in-app live chats, games and social features in our region. And we are constantly working on new ways to enhance the user experience. For instance, we rolled out our new livestreaming feature across all of our markets by the second quarter. This feature offers a new and powerful way for consumers to engage with our platform, brands and sellers through live video streams created by Shopee or by the sellers themselves. As consumers discover new products through this feature, they can make immediate purchases without leaving the stream. We also employed AI and AR technologies to further enhance consumer experience on our platform. For example, our new AI and AR powered tools, which were introduced in partnership with L’Oreal, enable our users to try different shades of make-up or get personalized, professional skincare advice in the Shopee app. In addition, we leveraged our unique strengths in both digital entertainment and social commerce by introducing esports streaming on the Shopee platform. This has helped us attract and better engage with an even broader audience across market segments. And just last week, we announced the world-famous footballer Cristiano Ronaldo as Shopee’s new brand ambassador in Southeast Asia and Taiwan. Ronaldo is one of the world’s best known athletes and an icon across our region. We are confident that our partnership with him will resonate with consumers and deepen their engagement with the Shopee brand. We believe that our focus on keeping our users engaged and entertained gives Shopee unique strengths in better attracting and retaining users. It also offers us numerous opportunities to better understand our users’ needs and preferences to help them discover more new products on our platform. To conclude, looking to the second half of the year, we believe we are in a great position to drive sustained growth across both e-commerce and digital entertainment, and to do so with increasing efficiency. That said, we are still very much in growth mode across our businesses. We have a great opportunity ahead of us to grow our markets over the long term and we are very well placed to capture the largest slice of this growing pie. As we have always said, we believe scale and strong market leadership will translate into long-term profitability. Our results for the second quarter demonstrate that our businesses become increasingly efficient as we scale, and we are committed to continuing scaling up to maximize those efficiencies. With that, I will invite Tony to share more about the financials.
