Cybersecurity Risk Management Strategy And Governance [Line Items]
Cybersecurity Risk Management Processes For Assessing Identifying And Managing Threats [Text Block]	Cybersecurity Risk Management and Strategy The Corporation recognizes the significance of cybersecurity in the financial industry and the potential risks associated, such as the risks arising from the loss of confidentiality, integrity, or availability of information systems. The Corporation’s processes to identify, assess, and monitor material risks from cybersecurity threats are part of its Enterprise Risk Management (“ERM”) Program, under which the Corporation has implemented a comprehensive Corporate Information Security Program (“CISP”). Cybersecurity risk is managed as part of the overall information technology risk, under the direction of the Corporate Security Office (“CSO”) led by the Corporate Security Officer (“CSO Officer”), who directly reports to the Chief Operations Officer. The CSO Officer also serves as Chief Information Security Officer (“CISO”). The CISP outlines the Corporation’s overall vision, direction, and governance to protect the confidentiality, integrity, and availability of customer information and seeks to prevent unauthorized access as required by regulatory guidelines and industry security best practices. The CISP is based on well-renowned frameworks such as the International Organizational Standard ISO 27000 series and the NIST Cybersecurity Framework. As such, it serves as a guide for the implementation of security safeguards across the Corporation and its subsidiaries. The CISP also addresses cybersecurity breaches and procedures for appropriate response efforts, including any required notification, depending on the severity of the specific security incident. In addition, the CISP incorporates a risk-based approach to ensure that risk is treated in a consistent and effective matter and is designed to protect classified information to prevent disclosure to unauthorized individuals; prioritize the use of information security resources by concentrating on critical business applications; develop quality, cost-effective, and reliable systems; ensure the proper and secure disposal of sensitive information; and implement adequate processes to ensure compliance. The ERM Program includes a Corporate Incident Response Program, which features a risk-based escalation process to manage corporate incidents, including cybersecurity incidents, and notify the Risk Committee of the Board of Directors and applicable stakeholders as appropriate. The Corporation incorporates the Information Technology (“IT”) Risk Unit of the ERM Department, which is comprised of several members such as IT Risk Managers and the ERM Director who is part of senior management, as well as external expertise, in the review of its processes, including an independent internal assessment of cybersecurity measures and controls. The Corporation also invests in threat intelligence, vulnerability management, and incident response drills. Furthermore, all of the Corporation’s employees and consultants with access to the Corporation’s network are required to complete a comprehensive cybersecurity awareness program on an annual basis. Additionally, awareness and training on information technology and cybersecurity risk is provided to the Board on a regular basis. The Corporation has a Vendor Management Program and a Third-Party Risk Management function to manage the cybersecurity risks associated with conducting business with third-party vendors, which includes the requirement for third-party vendors to implement appropriate measures to ascertain security and confidentiality of the Corporation’s resources. The Corporation places vendors into tiers based on the inherent risk due to the nature of the relationship with that vendor to determine any additional security requirements commensurate to such level of risk. The Corporation does not believe that risks from cybersecurity threats or attacks, including as a result of any previous cybersecurity incidents, have materially affected the Corporation’s business strategy, results of operations or financial condition as of December 31, 2024. While the Corporation continues to closely monitor cyber risk and has implemented processes that are intended to assess, identify, and manage material risks from cybersecurity threats, security controls, no matter how well designed or implemented, may only partially mitigate and not fully eliminate these risks. Events, when detected by security tools or third parties, may not always be immediately understood or acted upon. See Item 1A, “Risk Factors – Risks Relating to Cybersecurity and Technology” for more information on how cybersecurity risk could adversely affect the Corporation, which should be read in conjunction with this Item 1C.
