Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	We maintain a cybersecurity program designed to protect our systems and data from information security risks, including regular oversight of our programs for security monitoring. Gen has a process for identifying and assessing material risks from cybersecurity threats on a regular basis that operates alongside our broader overall risk assessment process, covering all identified enterprise wide risks. Cybersecurity risk is reviewed quarterly with management and with the board of directors. In addition, we regularly perform evaluations (including independent third-party evaluations) of our security program and our information technology infrastructure and information security management systems. A retained independent third-party firm reviews the maturity of our information security program and the results are discussed annually in the Technology and Cybersecurity Committee of the Board. Our processes also address risk and identification of cybersecurity threat risks from our use of third-party service providers. This involves, among other things, conducting pre-engagement risk-based diligence, reviewing security and controls reports, implementing contractual security and notification provisions, and ongoing monitoring as needed.
