Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Item 16K. Cybersecurity Our management and Board recognize the critical importance that a robust cybersecurity program and processes play in maintaining the integrity of our information technology networks and systems, which we rely upon to securely process, transmit and store electronic information and to communicate among our locations and with our customers and partners. We identify and address information security risks by employing a defense-in-depth methodology that provides multiple, redundant defensive measures in case a security control fails or a vulnerability is exploited. Our policies include procedures for handling urgent problems, accident classification standards, and internal audit standards for information security. We have passed Information Security Management Systems (ISMS) certifications such as ISO27001 and ISO27701, and we follow these and other international standards to assess, identify and manage cybersecurity threats. In addition to our internal resources, we also leverage external resources to mitigate cybersecurity threats to the Company, including partnering with third parties to conduct penetration testing, attack and defense exercises; perform annual audits and certifications of our cybersecurity and information technology processes and performance; and supply us with defensive tools. We have processes in place to oversee and identify risks that may arise from cybersecurity threats associated with our use of third-party service providers, including contract review procedures that apply to third party vendors handling or having access to company information. Our security team conducts additional cybersecurity due diligence on certain vendors involved in customer data sharing. Oversight of cybersecurity risk is integrated into our overall enterprise risk management framework. At the management level, our Chief Information Officer (“CIO”) oversees our cybersecurity program and risks, with more than 15 years of experience in the online advertising and fintech industry, including significant engineering experience and responsibility for building trading systems, anti-fraud systems, and risk management systems. Our CIO holds a M.S. degree in Computer Science from Institute of Software, Chinese Academy of Sciences, and a B.S. degree from Huazhong University of Science and Technology. Our CIO oversees our research and development (“R&D”) department, which is responsible for detecting, identifying, monitoring, and remediating IT and cybersecurity risks. The security team within the R&D department prepares and disseminates to vice presidents, team leaders and licensed entity team leaders a security monthly report regarding our security posture, critical business security metrics, security incidents, security audits, and other security-related matters. At the Board level, cybersecurity risk oversight has been delegated to our Operation Committee, which is a sub-committee of the Board of Directors composed of our non-independent directors. The Operation Committee meets weekly, and our CIO reports to the Operation Committee in the event any significant risks or incidents have been identified. In addition, the Operations Committee has an online working group where the CIO will promptly report any cybersecurity incidents and risks. To date, we have not identified any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that have, or are likely to, materially affect us, our business strategy, results of operation or financial condition.
