Cybersecurity Risk Management and Strategy

We have developed and implemented a cybersecurity risk management program intended to protect the confidentiality, integrity and availability of our critical systems and information.We design and assess our program based on the National Institute of Standards and Technology Cybersecurity Framework, or  NIST CSF, and the MITRE ATT&CK® framework. This does not imply that we meet any particular technical standards, specifications or requirements, only that we use the NIST CSF and MITRE ATT&CK® as guides to help us identify, assess and manage cybersecurity risks relevant to our business.Our cybersecurity risk management program is integrated into our overall enterprise risk management program and shares common methodologies, reporting channels and governance processes that apply across the enterprise risk management program to other legal, compliance, strategic, operational, and financial risk areas.Key aspects of our cybersecurity risk management program include the following:•risk assessments designed to help identify material cybersecurity risks to our critical systems, information, products, services and our broader enterprise IT environment;•a security team principally responsible for managing; (i) our cybersecurity risk assessment processes, (ii) our security controls and (iii) our response to cybersecurity incidents;•the use of external service providers, where appropriate, to assess, test or otherwise assist with aspects of our security controls and processes;•cybersecurity awareness training of our employees, incident response personnel and senior management; •a cybersecurity incident response plan that includes procedures for responding to cybersecurity incidents; and•a third-party risk management process for key service providers, suppliers and vendors.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 certain cybersecurity threats that, if realized, are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. See Item 1A “Risk Factors – Cyberattacks or other security incidents that disrupt our operations or compromise data, may expose us to liability, harm our reputation or otherwise adversely affect our business.”
