Cybersecurity Risk Management, Strategy, and Governance [Abstract]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Risk Management and Strategy We have implemented security measures and will continue to devote resources to address security vulnerabilities in an effort to prevent cyberattacks. All employees receive cybersecurity training and other education regarding their use of computers, information technology, and sensitive data. We utilize third parties to support our information technology, or IT, resources, including disaster recovery intended to safeguard our ability to access and use our IT resources during a disaster or cyber incident. Our business continuity plans are evaluated against evolving security and service level standards, which includes evaluating those cybersecurity threats associated with our use of key third party service providers. Our cybersecurity management process consists of utilizing a combination of employee education, preventative controls, detective controls, and periodic third-party cybersecurity testing. We have installed and utilize enterprise scale technology to support an appropriate cybersecurity posture including: endpoint detection and response, firewalls, security information and event management, email security, multifactor authentication, and vulnerability management. We receive cybersecurity related alerts from our membership in a number of industry groups. These alerts are evaluated and in the event an alert requires action within our environment, such actions are taken promptly. Our process and cybersecurity posture are refined based on the results of periodic third party cybersecurity assessments. We engage with the Cybersecurity and Infrastructure Security Agency through their cyber hygiene service offerings. Cybersecurity is addressed in IT’s reports to the Corporate Automation Steering Committee, which consists of all Officers and the Director of Customer Service, as well as in IT’s reports to the Board of Directors. Should a cyber event occur, depending on the severity of an event, our cyber incident reporting process includes informing, as early as practicable, our senior corporate management.
