Corporate Governance The Board recognizes the importance of developing, implementing, and maintaining appropriate cybersecurity measures to safeguard Century’s information systems and protect the confidentiality, integrity, and availability of Century’s data. The Board is actively involved in oversight of Century’s risk management program, and cybersecurity represents an important component of Century’s overall approach to enterprise risk management.
