Thank you all for taking the time to join our fourth quarter and full year 2019 results conference call today. First, I would like to send my greetings to those in Wuhan and all around the world as we are going through this difficult time. We grieve for the families that have been affected by it, and we salute those who have been or are still on the front lines fighting against the outbreak. As I mentioned in my letter to our colleagues, all of us play an important part in fighting this outbreak, and we expect the situation in China to stabilize soon as we are on track for business recovery. During the outbreak, we've made conscious efforts to support our borrowers in the heavily affected areas by loosening their repayment terms. Now to our business update. Even though 2019 has been a challenging year for the industry with rapidly evolving market conditions and a tightening regulatory environment, we have made significant progress in our strategic transformation to reposition our business as we enter 2020. First, we have completed the full operational integration of Yirendai with CreditEase inclusive finance and online wealth management business to form Yiren Digital, the leading fintech platform providing full spectrum of credit products to consumers and asset allocation-based wealth management services to mass affluent clients in China. Second, we made good progress in expanding our credit tax business model into loan facilitation as well as licensed lending operation model. Lastly, our online wealth management business has built a strong foundation and posed for significant growth in the years to come with strong momentum. For the full year of 2019, we have achieved RMB 8.6 billion net revenue, RMB 1.2 billion net profit and ended the year with RMB 3.6 billion usable cash, which puts us on a solid footing to weather near-term market volatilities and capture market opportunities as business activities recover. For our credit tax business, we are rolling out new product services and expanding customer acquisition channels to better reach and serve our borrowers. We launched a new micro credit loan product in November 2019 with smaller loan size and a short tenure, which is a preferred asset by our institutional bank partners. On top of that, in 2020, we plan to roll out a revolving line of credit products to better meet our borrowers' everyday financing needs. To fully leverage our nationwide service network coverage, we will be rolling out auto loans targeted at second-handed cars, which typically have a better risk profile than unsecured consumer loans. On customer acquisition front, we are looking to partner with large traffic channels like Xiaomi and work together to offer consumer credit services to their user base at the point of consumption. Next, to wealth management. We are seeing our non-P2P wealth management business gaining strong traction. In the fourth quarter of 2019, asset under advisory for non-P2P products grew 64% quarter-over-quarter and the sales volume grew 232% quarter-over-quarter. In particular, AUA for bank-structured deposit products exceeded RMB 600 million in November 2019. The number of current investors investing in non-P2P products increased to 21,000 as of December 31, 2019, from 15,000 as of prior year-end. To better serve our customers, we partnered with OneConnect and have on-boarded a selection of bank deposit products on our platform. In August 2019, we launched a team of 50 online financial advisers to provide one-on-one wealth management consulting services to fulfill each investor's diversified allocation needs. As of December 31, 2019, the number of investors that have invested in more than one type of asset on our platform increased over 60% from September 2019. For mutual funds, total asset and advisory of mutual fund has increased to RMB 287 million as of December 31, 2019, from RMB 222 million in previous quarter. And we are seeing a steady increase in average AUA per investor from RMB 23,000 in June 2019 to RMB 30,000 in December 2019. For insurance, GMV of insurance products increased 6x quarter-over-quarter, and we expect to see a further increase in demand for insurance products post the coronavirus outbreak. In 2020, we expect to maintain a strong growth momentum for our wealth management business as we continue to roll out more non-P2P products and services, including bond funds and savings space insurance through working with leading partners. Recently, we have entered into a strategic cooperation agreement with Principal Global Investors, a subsidiary of Principal Financial Group, a global investment management leader offering asset management, retirement services and insurance solutions to institutional clients, businesses and individuals. The partnership will open up a comprehensive strategic business deployment in China's retirement financial services market, helping China's mass affluent population better prepare for retirement. In addition, in Q4 2019, we obtained a Hong Kong stock brokerage license, and our stock trading app was officially launched in December 2019. We plan to roll out stock trading and consulting services in Q2 2020. Today, we also announced changes in our management team. Mr. Michael Ji will assume Chief Risk Officer of the company. Michael brings over 18 years of experiences in risk management and decision science with multiple top financial organizations, including Citigroup, JPMorgan Chase and Fleet Boston Bank. Mr. Jiangxu Xiang will be assuming the position of Chief Technology Officer of the company. Prior to joining us, Jiangxu had held multiple tech-related senior management roles at Suning, Microsoft and Cisco. In light of new regulatory guidelines for P2P companies, in 2020, we will be transitioning under different [tops] simultaneously. First, we will increasingly use our existing nationwide online micro lending license to lend. We are also considering applying for new financial licenses. Second, we will continue to expand our partnerships with licensed financial institutions to diversify funding sources. We have made strong progress in onboarding institutional funding this quarter, with RMB 40 billion line of credit secured and expect to further increase significantly in 2020 as we continue to expand our funding partners beyond commercial banks to trust and licensed consumer finance companies. Third, we are looking to make strategic investments in consumer finance company as well as potentially commercial bank. We are also applying for local financial guarantee license to ensure that our business will be fully licensed and compliant. Lastly, I would like to talk about how the coronavirus has impacted us. Over the past two months, we have proactively controlled loan volume growth as we started to see volatilities in delinquencies, largely impacted by a slow economy as well as disruption to our workforce, especially with our call center being based in Wuhan. As of the first week of March, 81% of our off-line workforce have returned to work and 85% of our call center have returned to work, and of which 65% are working from home due to ongoing traffic control in Wuhan. We expect business to gradually recover starting in April, and we are fully prepared to ramp up our business and expect a strong second half 2020. Now I'd like to turn over the call to our CFO, Zhong Bi, who will discuss our financial results for the quarter.
