Item 1C. Cybersecurity.

ITEM 1C. CYBERSECURITY Risk Management and Strategy Our risk management program is designed to identify, assess, and mitigate risks across various aspects of our company, including financial, operational, regulatory, reputational, and legal. Cybersecurity is a critical component of this program, given the increasing reliance on technology and potential of cyber threats. Our Chief Information Security Officer is primarily responsible for this cybersecurity component and is a key member of the risk management organization, reporting directly to the Chief Risk Officer and, as discussed below, periodically to the Technology Committee of our board of directors. Our objective for managing cybersecurity risk is to avoid or minimize the impacts of external threat events or other efforts to penetrate, disrupt or misuse our systems or information. The structure of our information security program is designed around the National Institute of Standards and Technology ( NIST ) Cybersecurity Framework, regulatory guidance, and other industry standards. In addition, we leverage certain industry and government associations, third-party benchmarking, audits, and threat intelligence feeds to facilitate and promote program effectiveness. Our Chief Information Security Officer and our Chief Information Officer, who reports directly to our Chief Consumer Banking Officer, along with key members of their teams, regularly collaborate with peer banks, industry groups, and policymakers to discuss cybersecurity trends and issues and identify best practices. The information security program is periodically reviewed by such personnel with the goal of addressing changing threats and conditions. We employ an in-depth, layered, defensive strategy that embraces a trust by design philosophy when designing new products, services, and technology. We leverage people, processes, and technology as part of our efforts to manage and maintain cybersecurity controls. We also employ a variety of preventative and detective tools designed to monitor, block, and provide alerts regarding suspicious activity, as well as to report on suspected advanced persistent threats. We have established processes and systems designed to mitigate cyber risk, including regular and on-going education and training for employees, preparedness simulations and tabletop exercises, and recovery and resilience tests. We engage in regular assessments of our infrastructure, software systems, and network architecture, using internal cybersecurity experts and third-party specialists. We also maintain a third-party risk management program designed to identify, assess, and manage risks, including cybersecurity risks, associated with external service providers and our supply chain. We also actively monitor our email gateways for malicious phishing email campaigns and monitor remote connections as a significant portion of our workforce has the option to work remotely. We leverage internal and external auditors and independent external partners to periodically review our processes, systems, and controls, including with respect to our information security program, to assess their design and operating effectiveness and make recommendations to strengthen our risk management program. We maintain an Incident Response Plan that provides a documented framework for responding to actual or potential cybersecurity incidents, including timely notification of and escalation to the appropriate Board-approved management committees, as discussed further below, and to the Technology Committee of our board of directors. The Incident Response Plan is coordinated through the Chief Information Security Officer and key members of management are embedded into the Plan by its design. The Incident Response Plan facilitates coordination across multiple parts of our organization and is evaluated at least annually. Notwithstanding our defensive measures and processes, the threat posed by cyber-attacks is severe. Our internal systems, processes, and controls are designed to mitigate loss from cyber-attacks and, while we have experienced cybersecurity incidents in the past, to date, risks from cybersecurity threats have not materially affected our company. For further discussion of risks from cybersecurity threats, see the section captioned Our Information Systems May Experience Failure, Interruption Or Breach In Security in Item 1A. Risk Factors. Governance Our Chief Information Security Officer is accountable for managing our enterprise information security department and delivering our information security program. The responsibilities of this department include cybersecurity risk assessment, defense operations, incident response, vulnerability assessment, threat intelligence, identity access governance, third-party risk management, and business resilience. The foregoing responsibilities are covered on a day-to-day basis by a first line of defense function, and our second line of defense function, including the Chief Information Security Officer, provides guidance, oversight, monitoring and challenge of the first line s activities. The second line of defense function is separated from the first line of defense function through 35 Table of Contents organizational structure and ultimately reports directly to the Chief Risk Officer. The department, as a whole, consists of information security professionals with varying degrees of education and experience. Individuals within the department are generally subject to professional education and certification requirements. In particular, our Chief Information Security Officer has substantial relevant expertise and formal training in the areas of information security and cybersecurity risk management. Our board of directors has approved management committees including the Information Technology Risk Committee, which focuses on technology impact, and the Information Security Oversight Committee, which focuses on business impact. These committees provide oversight and governance of the technology program and the information security program. These committees are chaired by managers within the enterprise information security department and include the Chief Information Security Officer and Chief Information Officer as well as their direct reports and other key departmental managers from throughout the entire company. These committees generally meet monthly to provide oversight of the risk management strategy, standards, policies, practices, controls, and mitigation and prevention efforts employed to manage security risks. More frequent meetings occur from time to time in accordance with the Incident Response Plan in order to facilitate timely informing and monitoring efforts. The Chief Information Security Officer reports summaries of key issues, including significant cybersecurity and/or privacy incidents, discussed at committee meetings and the actions taken to the Technology Committee of our board of directors on a quarterly basis (or more frequently as may be required by the Incident Response Plan). The Technology Committee of our board of directors is responsible for overseeing our information security and technology programs, including management s actions to identify, assess, mitigate, and remediate or prevent material cybersecurity issues and risks. Our Chief Information Security Officer and our Chief Information Officer provide quarterly reports to the Technology Committee of our board of directors regarding the information security program and the technology program, key enterprise cybersecurity initiatives, and other matters relating to cybersecurity processes. The Technology Committee of our board of directors reviews and approves our information security and technology budgets and strategies annually. Additionally, the Risk Committee of our board of directors reviews our cyber security risk profile on a quarterly basis. The Technology Committee and Risk Committee of our board of directors each provide a report of their activities to the full board of directors at each board meeting.
