Thank you, Forrest. Within digital entertainment, we continued to strengthen our market leadership. Forrest has outlined adjusted revenue and adjusted EBITDA results. Garena continues to deliver significant free cash flow. Our digital entertainment adjusted EBITDA margin rose to 38% in the first quarter of 2018 compared to 36% in the same period in 2017, revealing further margin leverage as Garena benefits from greater scale.
I would like to share with you one more facet of Garena's expanding role in the mobile edge. As smartphones continued to improve access to gaming, a greater number of people are gaining access to better forms of entertainment. This will lead to an increase in demand from mobile gamers for high-quality content and as a result, we expect to see sustained growth in the popularity of leading multi-year mobile game franchises, similar to what we've seen for PC. And as the game franchises grow, their ancillary ecosystem starts to develop as well, which will, in turn, spark greater demand from increasingly sophisticated mobile gamers for better on-the-ground game services and community building. Given our position as a leading gaming platform, our geographic reach, our long-running on-the-ground presence in these markets and our track record of success, we believe that Garena is well-positioned to provide such services.
These factors are also key enablers to our dominance in eSports. We have become one of the region's most fully integrated eSports operators, since our inception in 2009. Critical to our successes, the extensive network of community leaders we've attracted across various markets. We work closely with them to run thousands of local eSports events. On top of this infrastructure, we have a suite of capabilities, supporting eSports content production, particularly in our largest markets. We're pretty clearly excited about the rapid expansion in eSports activities around Arena of Valor, which, with Honor of Kings, constituted the world's largest grossing gaming franchise, based on the latest data available. We also expect the inclusion of League of Legends and AOV as eSports at the Asian games in Jakarta to generate additional enthusiasm in gameplay around these titles.
In terms of operational results, quarterly active users, or QAU, meanwhile, grew 125% year-on-year and 44% quarter-on-quarter to $126.7 million, largely driven by existing games such as Arena of Valor and Free Fire. Meanwhile, average revenue per user, or ARPU, came in at $1.20 compared to $1.80 for the first quarter of 2017 and $1.60 for the fourth quarter of 2017. The easing in ARPU is mainly due to rapid user growth around Free Fire, which resulted in faster QAU compared to quarterly-paying users, or QPUs. QPUs remained stable at $7.2 million in the first quarter of 2018. As Forrest has mentioned, our focus for Free Fire, right now, is to build up a pool of long-term gamers. We are, indeed, experimenting with different monetization tools in parallel albeit at a gradual pace.
With regards to e-commerce, the markets in our region continue to grow strongly. Frost & Sullivan, for instance, just released its quarterly e-commerce report, which estimated that first quarter 2018 GMV for Southeast Asia and Taiwan grew 45% year-on-year to USD 10 billion. Based on their analysis of our region, Shopee is the largest e-commerce platform by orders in all markets other than Singapore. Once again, Shopee had an outstanding quarter with GMV reaching $1.9 billion, almost triple the GMV for the first quarter of 2017 and representing quarter-on-quarter growth of 23%. Shopee's gross orders reached $111.4 million, which more than tripled year-on-year.
Our ability to grow at such a rapid pace and an increasingly competitive market is testament to the Shopee management team's outstanding execution. In fact, Shopee's pace of growth is ahead of our already ambitious expectation and as we disclosed in our release, we've adjusted our revenue and GMV guidance for the full year 2018 to reflect our confidence in sustaining this strong momentum.
Our sales and marketing expenses declined in absolute terms from $135 million in the fourth quarter of 2017 to $127 million in the first quarter of 2018, reflecting how well we are managing our spending while still driving strong GMV growth. As S&M as a percentage of GMV decline from 8.5% in the fourth quarter to 6.6% in the first quarter. In addition, we are pleased to share with you that this quarter, we have value-added services contributing to our e-commerce adjusted revenue. Forrest touched on these offerings and Tony will go into greater detail around these items in his remarks. Our ability to offer such value-added services, is in many ways, driven by: One, the unique characteristics of the markets we serve; two, the less-developed e-commerce value chains found in our region; and three, our unique and growing skill set in servicing sellers. We expect these value-added services to grow and the business model to improve with the rising scale, efficiency and constant service improvement.
We also continue to cultivate our direct sales business, which has contributed to growth in product revenue. As we have referenced on previous calls, we have begun to offer direct sale service to select sellers, particularly larger brands. We view these services as an effective strategy to improve many aspects of our marketplace. They are, for instance, ideal for fast-moving SKUs with demanding fulfillment needs. With regards to our digital financial services business, we continue to focus our efforts on strengthening our infrastructure to support our existing platforms.
With that, I will pass on to Tony to talk more about the financials.
