Cybersecurity Risk Management, Strategy, and Governance [Line Items] |
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | We maintain a cyber risk management program to identify, assess, manage, mitigate, and respond to cybersecurity threats. We design and assess our program based on the National Institute of Standards and Technology Cybersecurity Framework (NIST CSF) and use the NIST CSF as a guide to help us identify, assess, and manage cybersecurity risks relevant to our business. The program is integrated within our enterprise risk management system and addresses our IT networks and related systems that are essential to the operation of our business. We maintain controls and procedures, including third-party oversight procedures, and cybersecurity training for all employees on an annual basis, which are designed to ensure prompt escalation of cybersecurity incidents so that decisions regarding public disclosure and reporting of such incidents can be made by management in a timely manner. We work with third parties that assist us to identify, assess, and manage cybersecurity risks, including professional services firms, consulting firms, threat intelligence service providers, and penetration testing firms. Our cybersecurity program and designated incident response team are comprised of key employees, and third-party information security experts from leading cybersecurity incident response firms, who are responsible for efficiently and effectively responding to cybersecurity incidents. We have established comprehensive incident response and recovery plans and continue to evaluate the effectiveness of those plans. We have not identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected us, including our operations, business strategy, results of operations, or financial condition. We face risks from cybersecurity threats that, if realized, are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. See “Risk Factors – We rely on information technology in our operations, and any material failure, inadequacy, interruption or security failure of that technology could harm our business.”
