Thanks Howard. Hello everyone and thank you for joining today's call. I'm very pleased to announce that we closed out 2018 well ahead of our ambitious targets. Building on our strong results in the fourth quarter, we exceeded the high-end of each of the projections we provided in our latest guidance last year. Let me start by quoting out Garena's success. Our Digital Entertainment adjusted revenue for the full year of 2018 reached $661 million, exceeding the high-end of our guidance by $41 million. In the fourth quarter, we recorded adjusted revenue of $231.4 million, up 50% from the third quarter and it is expected to show further robust growth in the first quarter of 2019. And our adjusted EBITDA margin for the quarter grows to 45.5% compared to 37.2% for the previous quarter. It is expected to improve further in the first quarter of 2019. We believe Garena's consistent strong performance underlines our success in executing our core strategy to materially expand our Digital Entertainment business from being a PC-focused regional publisher to a global developer and publisher, with core strengths in mobile games and the key focus on emerging markets, which greatly expands our total addressable market size. Free Fire is now one of the most popular battle royale games in the world. We recently hit a new record high of more than 350 million registered users and the more than 40 million peak daily active users. According to App Annie, for the full year of 2018, Free Fire was the fourth most downloaded mobile game in the world across the Apple App Store and the Google Play Store combined. It has also hit the milestone of recording more than 100 million monthly active users. Importantly, we are also making excellent progress on monetizing Free Fire's massive and highly active user base. And this is reflected in our adjusted revenue growth and EBITDA margin improvement. One of the crucial factors in Free Fire's growth is the fast growing and engaged global community of players. Building on this strong community sentiment, from late 2018 we have been rolling out the Free Fire World Cup a global eSports tournament. We believe this global tournament will help to drive sustained excitement and solidify Free Fire's position as one of the leading games in that genre globally. As Free Fire's success has demonstrated, we believe that Garena has built a unique set of capabilities in developing and publishing global hit games that also address the needs of gamers in faster growth emerging markets. We have a deep understanding of the unique profiles and the needs of gamers in such market and unrivaled access to data and insights about these gamers because of our huge user base. We are also deeply rooted in these markets with strong local operations capabilities, and not only in our core markets, but also in other major markets like Latin America. More importantly, with our strong technology and execution capabilities, we are able to quickly identify and take advantage of market opportunities. We now have a strong and growing game development team with more than 200 developers in our games studio in Shanghai. We're working on enhancing Free Fire and on building out our self-developed games pipeline. Free Fire is a great example of how quickly we're able to identify and tap into new market opportunities. It was one of the first mobile battle royale games to come to market. At the same time, our game publishing business continues to grow from strength to strength as global IP holders recognize our unrivaled ability to tap into the faster growing game communities in our region. For instance, we have begun loading out Speed Drifters as the first game that we are publishing under our right of first refusal arrangement with Tencent that we announced last quarter. And I'm pleased to say that we have agreed with PUBG Corporation to bring into our key markets in Southeast Asia PUBG LITE, a PC game adapted from their global hit game PUBG tailored to our region. Looking to the year ahead, we intend to continue to drive growth in our Digital Entertainment business as we continue to build out a world class in-house game development arm and strengthening our publishing capabilities. Turning to E-commerce. Our goals for Shopee in 2018 were to continue to strengthen its market leadership position across its key markets with increasing efficiency and to ramp up monetization, and I'm pleased to say that we have delivered on all fronts. E-commerce GMV for the fourth quarter was $3.4 billion representing, 27% growth on the $2.7 billion in the third quarter. During the quarter, we recorded 206.9 million orders, up 31% from the third quarter. Meanwhile, during the 24 hours of our 11.11 Sale in 2018, we hit a new record for Shopee of over 11 million orders in a single day. And just one month later, during our 12.12 sale we broke that again recording over 12 million orders in 24 hours on December 12. On top of those 12 million orders, approximately 5.4 million came from our largest market Indonesia. Shopee's continuing solidification of leadership in Indonesia is a powerful demonstration of the strong flywheel effect it enjoys. In the fourth quarter, Shopee recorded total orders of 83.8 million or a daily average of 0.9 million in Indonesia, further extending its leadership as the largest E-commerce platform there. For the full year of 2018, Shopee achieved $10.3 billion in GMV, which was above the high end of the recent guidance of $9.7 billion. We provided in the third quarter. Reaching $10 billion in annual GMV was an important milestone for Shopee and an impressive achievement for platform that is just a three years old. You can see the sustained improvements in the efficiency of our sales and the marketing spend. In the fourth quarter, sales and marketing expenses as a percentage of GMV fell once again to 5.4% down from 5.7% last quarter and 8.5% for the same period a year ago. In fact, shipping subsidies declined in absolute dollar terms in the fourth quarter compared to the third quarter. It is important to note that Shopee achieved this sustained improvement in marketing efficiency while its GMV grew by 27% and orders grew by 31% quarter-on-quarter, demonstrating that we are able to both grow our platform, while increasing efficiency at the same time. We are able to do this because of the durable leadership position we have achieved. We expect the sales and marketing expenses to start trending down in absolute dollar terms this year, as we continue to scale with greater efficiency, benefit from strong organic user growth and solidify our market leadership in the region. On the monetization front, E-commerce adjusted revenue grew over 16x year-on-year to $290.7 million for 2018 as ramp up our monetization efforts during the year. And in the fourth quarter adjusted revenue grew more than 78%, compared to the third quarter to $126.9 million. Moreover, we expect Shopee to record a positive quarterly of adjusted EBITDA before allocation of the headquarters' common expenses for the first time in the first quarter of 2019 in Taiwan. We see the same dynamics around network effects that accrued to clear leader in a two-sided marketplace model starting to play out in our other markets. Shopee's ability to grow rapidly over a short period of time to achieve regional market leadership is a testament to its successful strategy and ability to execute that strategy efficiently and effectively. Shopee has been focusing on building a mobile-centric socially engaging marketplace with an emphasis on high margin products from a highly diverse seller base. In addition to that, Shopee has also combined its marketplace offering with integrated payments, logistics, infrastructure and the comprehensive seller services. And looking to the year ahead, we believe this strategic focus and our proven track record of successfully executing on our strategies we'll continue to drive growth at Shopee. In 2019, we intend to focus on growing with efficiency, while looking to further ramp up monetization through deeper engagement with our sellers and the buyers. To sum up, I'm very proud of our performance in the fourth quarter and the full year of 2018. Across the business, 2018 was a transformative year as Shopee extended its lead in E-commerce and Garena emerged as the leading global game developer and publisher. We enter into 2019 in a stronger position than ever before, poised for growth on all fronts. We are hugely excited for the year ahead and have once again set ambitious growth targets for ourselves as reflected in our guidance for 2019. With that, I will invite Tony to share more about the financials.
