Thank you, Ripple. Good morning, and good evening to everyone, and thank you for joining us today. Frankly speaking, from the rapid expansion of our mono wafer production capacity during the second half of 2019, and our industry-leading integrated cost structure, we closed out the year with a very strong performance in which solar module shipments total revenue and gross profit all hit record highs for both the fourth quarter and the full year. EBITDA was $380 million in 2019. Non-GAAP net income for the year came in at $140 million, while gross margin expanded to 18.3% or significantly improved when compared to last year. 2019 marked a significant milestone in our corporate history in which we successfully completed our transformation into the most competitive solar manufacturer in the world. The efficient execution of our strategy throughout the second half of the year allowed us to rapidly transit operations and facilities from multi to mono production and steadily increase the proportion of products made through our fully integrated manufacturing process. This allowed us to rapidly begin mass production of our innovative solar products and distribute them to our growing customer base, eager to benefit from their increased efficiency. We also further refined management process to further optimize operational efficiency across our business and supply chains, which significantly reduced manufacturing costs. As a result, we closed out the year with a significantly expanded share of the global market, which ideally positions us to continue doing so in the year ahead, where we expect solar module shipments to increase by approximately 35%. New installations globally grew steadily throughout the year. New installations in Europe doubled in 2019, while ASPs in the United States remained high as a result of constrained supply. A number of emerging markets are flourishing with many of them approaching gigawatt levels, which we believe reflects the direction the market is headed with demand diversifying globally instead of being concentrated in a few large markets with great parity rapidly approaching. The long-term growth potential of the industry is rapidly opening up. Governments across the globe are increasingly devoting more resources towards the development of clean energy and are quickly rolling out plans with medium to long-term targets for clean energy production. We believe global demand in 2020 will continue generating strong growth momentum with newly added inspirations, expected to be in the range of 140 to 150 gigawatt, an increase of around 20% year-over-year. Turning to the domestic market, the delayed announcement of the government subsidy policy for PV projects in China in 2019 left little time for companies to plan and submit project divestment applications, which result in many of them being pushed back into 2020. The subsidy for 2020 is finalized earlier in the year. That was down last year, which will allow more time for project development, planning and application, and will result in higher overall completion rate. With a number of projects from 2019 delayed into 2020, total installations in China is expected to be in the range of 40 to 50 gigawatts in 2020, an increase of about 50% year-over-year. I will let Gener go into this in more detail later. Since the beginning of 2020, China has been fighting the outbreak of COVID-19. Local governments across the nation have implemented a series of comprehensive and stringent measures to prevent its spread and bring the outbreak under control. These measures included extending the Chinese New Year holiday, organizing and distributing medical resources and strict controls on transportation, which has impacted the solar industry. Based on our internal data, denying the return to work created a shortage of certain raw materials leading for production impacts, OEM capacity and creating logistics, bottlenecks and delays. This has affected the module shipments during the first quarter, which has been postponed to the second quarter. In response to the outbreak, we implemented a number of initiatives to ensure business continuity, including ensuring the safety and health of our employees and minimizing the impact on production and the delivery side impacting us on critical raw materials and optimizing production and logistics. The situation is gradually improving as the economy is gradually up. The temporary impact on our supply chain and logistics has improved, and our current capacity utilization rate has already reached 100%. We estimate that 400 to 500 megawatts of our solar module shipments in the first quarter will be delayed into the second quarter, which will cause shipments in the second quarter to increase significantly. Thanks to these measures we believe the impact on our shipments and capacity expansion plan for the full year of 2020 will not be impacted. Technology remains key to strengthening our competitive edge in the market. We increased our investment into R&D in 2019, which results in our product breaking sales, efficiency and module output world record, twice in June 2019 and once in January 2020. We recently appointed a Chief Technology Officer, who will lead and accelerate our R&D efforts and quickly apply them to the mass production of our solar product. In May 2019, we officially launched the latest addition to our range of premium Cheetah products, the "Swan" bifacial module with Clear DuPont Tedlar-based backsheet. The modules comprehensive performance, quality, innovative design and industry application was recognized with the receipt of the Intersolar award 2019. In October 2019, we set a new standard for the industry with the launch of a new high efficiency Tiger module using 9-busbar Mono PERC and Tiling Ribbon technology. We were the first in the industry to solve technical problems using Tiling Ribbon technology, and the first to begin mass production of high-efficiency modules with minimum cost. As part of our differentiated product strategy, we released a new generation of N-type modules tailored for the residential market, which has been widely adopted by customers for its ultra high-efficiency and cost effectiveness. These breakthroughs demonstrate our ability to lead the industry technologically in terms of power generation efficiency and energy density. Going forward, we will continue to allocate resources towards the development of cutting-edge technologies and accelerate the mass production of our innovative products, leveraging the significant advantage our fully integrated industrial chain provides. In 2019, our ability to constantly drive technological breakthroughs, coupled with our expanding production capacity for high-efficiency products continue to drive down manufacturing costs. Our integrated cost structure now needs the industry. On wafer side, we are applying our integrated monocrystal furnace controlling system, which is high, tiny, automated, and integral and intelligence to the production concept, which will further improve production quality and efficiency. On the sales side, we expanded and updated PERC capacity by 4 gigawatt within 4 months, breaking an industry record. We also lead the industry in the mass production of 500 megawatts ultra-high efficiency N-type sales with leading conversion efficiency currently available. On module side, we are maintaining our leading position in terms of module shipments, manufacturing cost and product quality, and leveraging our global footprint and fully integrated industrial chain. The competitiveness of products in the market today is driven by the technologies they incorporate. The ability to invest heavily in R&D and apply new technologies to the mass production is increasingly concentrating among a few players in the industry, who have the capacity, concentration and industrial scenarios needed to drive the process forward. We believe the market will continue to be concentrated among a few leading players going forward and will allow us to continue growing our market share over the next few years. On capacity side, our in-house mono wafer solar sale and high-efficiency solar module production capacity has now reached 11.5 gigawatt, 10.6 gigawatt and 16 gigawatt, respectively, at the end of the fourth quarter of 2019, given the rapid release of capacity as part of Phase 2 of the Leshan project and production and efficiency increase. From existing capacity, we expect our mono wafer capacity to reach 18 gigawatt in April 2020. Meanwhile, the 800 megawatt of ultra-high efficiency N-type sales project has reached full capacity in the fourth quarter of 2019. In addition, to meet growing demand of our innovative mass productive products, we will proactively expand mono -- expand module capacity by 9 gigawatt later from the second quarter of 2020. Before turning over to Gener, I would like to quickly go through our guidance for the first quarter of 2020. Based on current estimates and the impact from the outbreak of COVID-19, we expect total solar module shipment to be in the range of 3.4 gigawatt to 3.7 gigawatt for the first quarter of 2020. Total revenue for the first quarter is expected to be in the range of $1 billion to $1.08 billion. Gross margin for the first quarter is expected to be in the range of 19% to 21%. We will reiterate our guidance for full year 2020 shipments to be in the range of 18 gigawatt to 20 gigawatt.
