Item 1C. Cybersecurity.

Item 1C. Cybersecurity Cybersecurity Risk Management, Strategy and Governance Disclosures 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 various cybersecurity frameworks and guidelines. This does not imply that we meet any particular technical standards, specifications, or requirements, only that we use these frameworks and guidelines as a guide to help us identify, assess, and manage cybersecurity risks relevant to our business. Our cybersecurity risk management program is integrated into our overall risk management program, and shares common methodologies, reporting channels and governance processes that apply across the risk management program to other legal, compliance, strategic, operational, and financial risk areas. Key elements of our cybersecurity risk management program include the following: - risk assessments designed to help identify material risks from cybersecurity threats to our critical systems and information; - a dedicated information security team principally responsible for managing (1) our cybersecurity risk assessment processes, (2) our security controls, and (3) our response to cybersecurity incidents; - the use of external service providers, where appropriate, to assess, test or otherwise assist with aspects of our security processes and controls; - cybersecurity awareness training of our employees, including 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 based on our assessment of their criticality to our operations and respective risk profile. 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, financial condition, or results of operations. We face risks from cybersecurity threats that, if realized, are reasonably likely to materially affect us, including our operations, business strategy, financial condition, or results of operations. See Part I, Item 1A. "Risk Factors-Risks Relating to Our Business and Industry - Security breaches of our IT Systems, improper or unauthorized access to or disclosure of our Confidential Information, other hacking and social engineering or phishing attacks on our IT Systems or service, or other cyber incidents could disrupt our services or compromise Confidential Information related to our business and expose us to liability, which could harm our reputation and materially adversely affect our business.". Cybersecurity Governance Our Board considers cybersecurity risk as part of its risk oversight function and is assisted by its Audit Committee (the "Committee"), which regularly reviews our cybersecurity program with management and reports to the Board . Cybersecurity reviews by the Committee generally occur quarterly or more frequently as determined to be advisable. Committee members also receive presentations on cybersecurity topics and trends from our Information Security Management Leader, internal cybersecurity staff or external experts as part of the Committee's continuing education on topics that impact public companies. Our management team oversees our cybersecurity risk management through our Information Security Management System Governance Council, which is chaired by our Information Security Management Leader and includes our Chief Technology Officer, Chief Engineering Officer, and General Counsel , along with employee subject matter experts in law, privacy, engineering, and cybersecurity. This Governance Council also includes our Head of Information Security, who with our dedicated Information Security Team, manages the day-to-day activities needed to prevent, detect, and mitigate cybersecurity incidents, and reports to senior management through the Governance Council. This Head of Information Security has served in various roles within the cybersecurity field for over 15 years, including security leadership roles in multiple organizations and holds an undergraduate degree in information security and forensics. Our management team supervises efforts to prevent, detect, mitigate, and remediate cybersecurity risks and incidents through various means, which may include briefings from internal security personnel; threat intelligence and other information obtained from governmental, public or private sources, including external consultants engaged by us; and alerts and reports produced by security tools deployed in the IT environment.
