The Board of Directors is responsible for oversight of the Company’s information security program, which is designed and implemented by management under the direction of the Chief Information Officer. In addition, the Internal Auditor and Risk Management Officer consider cybersecurity threat risks alongside other company risks as part of our overall risk assessment and management process. The Chief Information Officer supervises the information security team, which is responsible for maintaining and implementing our enterprise-wide cybersecurity strategy, policy, standards, and architecture processes. The Information Security Officer, in coordination with compliance and human resources, conducts annual and ongoing company-wide information security awareness training.

We have developed processes to identify and oversee risks from cybersecurity threats associated with third-party service providers, which include the information security team assessing cybersecurity robustness during third-party vendor onboarding, the inclusion of protective provisions in third-party vendor agreements, and risk-based monitoring of third-party vendors on an ongoing basis.

The Company also engages with key third-party vendors, industry participants, government agencies, and intelligence and law enforcement communities as part of our efforts, which are reported to the Technology Steering Committee and Board of Directors. The Company has experienced and expects that it will continue to experience cyber-based attempts to compromise its information systems, although none, to its knowledge, has had a material adverse effect on its business, financial condition, or results of operations. Like all financial institutions, the Company faces the risks of such threats, the consequences of which could be material. See Item 1A – Risk Factors – “Cybersecurity breaches and technological discussions could damage our reputation and profitability,” above. In addition, given the constant and evolving threat of cyber-based attacks, the Company incurs significant costs in its efforts to detect and prevent security breaches and incidents, and these costs may increase in the future.
