Thanks, Jimmy. Hello, everyone, and thank you for joining our earnings call. I'm Tiezheng Li, Co-Founder of the company and it's a pleasure today and speak with all of you today. I'm deeply honored to take on the role of Chief Executive Officer and excited to explore the great opportunities and the prospects ahead for FinVolution. We are happy to speak with you today following the conclusion of another turbulent year on a strong note. 2022 was a complicated year given the complex macro environment. The situation in the domestic market has been very challenging with the pandemic resurgence throughout the year, leading to varying degrees of lockdown across multiple cities. The Shanghai lockdown was particularly difficult for us as most of our core teams are based here. However, despite all these challenges, we continue to build on our priority technologies in industry-leading digital capabilities, delivering resilient growth each quarter and ultimately producing another set of record-breaking operational and financial results to close out the year. We have invested wisely in the technologies throughout the year and are pleased to share that as of December 2022. We have successfully registered 212 software copyrights and filed 162 patents in fintech-related areas. For full year 2022, we achieved our total transaction volume target with RMB 175.4 billion in total transactions, representing a year-over-year increase of 28%. Our total transaction volume in the fourth quarter reached RMB 48.6 billion, representing a year-over-year increase of 25% and a sequential increase of 7%. Notably, our full year domestic loan volume grew to RMB 171 billion, a year-over-year increase of 28%, and the fourth quarter volume rose to RMB 47 billion, a year-over-year increase of 24% and a sequential increase of 6%. Thanks to our effective local focus, global outlook strategy. International loan volume for the full year also climbed to RMB 4.3 billion, representing a year-over-year increase of 16% where loan volume for the fourth quarter reached RMB 1.4 billion, representing an increase of 41% year-over-year. Concurrently, our total outstanding loan balance stands at RMB 64.6 billion, a year-over-year increase of 28%. Our outstanding loan finance in China totaled RMB 63.8 billion, an increase of 28% year-over-year. And the international markets, this number has soared to RMB 0.8 billion, representing a year-over-year increase of 167%. Solid management experience as well as excellent execution throughout the year helped us to overcome the year's challenging period, leveraging our cutting-edge technologies such as RTA for new borrowers acquisition. Our Octopus system for operation of advertisement targeting high-quality borrowers, our Magic Mirror for credit risk assessment and our Ming Mirror for fraud detection. We delivered robust operational and financial results, fostered by our prudent approach to risk management and our advanced credit risk assessment model. Our vintage delinquency rates remained stable and healthy between 2.3% to 2.4% throughout 2022. In 2023, as China reopens, we expect further improvements in these metrics. We also maintained a strong loan collection recovery rate of approximately 90% in the fourth quarter, even in some turbulence surrounding the easing of Zero COVID policy in December 2022. With our ongoing efforts to acquire better quality borrowers, our proportion of category A and B borrowers in the domestic market further increased to 77% of our total borrowers in the fourth quarter from 63% in the same period last year. Coupled with a larger proportion of better quality borrowers, we have also completely paid our price transition. Our average borrowing rate was 23% in the fourth quarter, reaffirming our commitment to financial inclusion where bolstering our compliance level and alignment with regulatory directives. Looking ahead, we expect borrowing rates to be in the range of 22% to 23% in 2023 due to the increase in the proportion of category A and B borrowers. Notably, the transition to better quality borrowers has also helped us to reduce our funding costs, which dipped below 7% in the fourth quarter of 2022 compared with 7.8% in the same period last year. We have cumulatively incorporated with 75 financial institutions and our pipeline of potential partners remains robust. Looking ahead, we are confident we can achieve progressive improvements in our funding costs as our proportion of category A and B borrowers continue to rise. Moving on to our second growth driver, our international expansion. We are thrilled to report that during the fourth quarter, improvement across multiple operational fronts led to a revenue contribution of RMB 395 million from this segment, representing a 13% contribution to total revenue as well as an increase of 122% from the same period last year and a sequential increase of 13% from the previous year -- quarter. For full year 2022, revenue from the international segment was RMB 1.15 billion or 10.3% of total revenue, a remarkable accomplishment given the international contribution to total revenue just reached a double-digit level for the first time in the third quarter. Indonesia continued to be the major international market in 2022, although pandemic-related rules and restrictions have relaxed in many countries. We remain cautious and we'll adjust our strategy according to suite local circumstances. Since 2021, we have been targeting better quality borrowers with attractive interest rates in Indonesia. And our efforts have been recognized by well-known local financial institutions such as Bank Jago, Bank Permata and the OCBC NISP. Among others, growing fruitful collaboration with these local partners have led to a rapid increase in our proportion of loan funded by local banks to 63% in the fourth quarter of 2022 compared to 48% in the previous quarter and merely 10% in the same period last year. Our success in Indonesian market is sparing and has strengthened our confidence as we expand into additional countries. For example, our outstanding loan financing in the Philippines during the fourth quarter grew over 110% year-over-year. Going forward, we plan to accelerate our pace of penetration in Indonesia and the Philippines, while evaluating other potential opportunities in the region. Based on our current assessment, we believe revenue contributions from the international markets will continue to climb in 2023, rising to between 15% to 20% of total revenue, further diversifying our revenue sales. Last but not least, I'd like to briefly update you on our ESG performance. We published our fourth annual ESG report in 2022, providing a snapshot of our forward-looking thinking efforts and initiatives aimed at driving sustainability and enhancing value creation for our stakeholders. We also joined the United Nations Global Compact program, a voluntary initiative to implement universal sustainability practice, demonstrating our corporate value and the long-standing dedication of fulfilling our social responsibilities. Furthermore, we were proud to receive a low-risk ESG rating from Sustainalytics for the second consecutive year, a powerful testament to our vision for the future of ESG as well as our current accessibility policies and practices. Going forward, we will strive to promote our aspects of ESG in our operations, including corporate governance and behavior, data privacy and security, human capital development, environment protection and corporate social responsibility. To ensure alignment with the international best practice and enhance our holistic approach to ESG, we plan to expand to our cooperation with additional independent ESG rating platforms in 2023. In summary, our outstanding overall performance in 2022 underscores our strength and stability as well as our team's ability to overcome challenges. We have built a firm foundation that will empower us to drive long-term sustainable quality growth as we forge ahead in 2023, we will continue to embrace our local focus, global outlook strategy, building on our domestic strength and success with an emphasis on serving better quality borrowers while evaluating more countries and regions to advance our global expansion. Meanwhile, we will remain dedicated to expanding our healthy customer base, optimizing our product mix and leveraging our technology or logical capabilities to further refine our risk assessment and management framework. With these advantages, we believe that we are well situated the capital life and on the massive opportunities that lie at a height and create greater value for our customers, shareholders and all of our stakeholders.
