Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Overview of Cybersecurity Risk Management The Company maintains a cybersecurity program that is designed to identify, prevent, detect, respond to, and recover from cybersecurity threats, and protect the confidentiality, integrity, and availability of our information technology, including the information residing on such systems. The Company has established the role of Chief Information Security Officer (“CISO”) with overall responsibility for developing and implementing the global cyber strategy, risk management, and operational initiatives. The Company's former CISO departed at the end of 2025. An active search for a qualified replacement is in process. In the interim, the Chief Information Officer (“CIO”), a member of the executive leadership who has over 30 years of enterprise IT experience and to whom the CISO role has reported since 2019, is managing the CISO responsibilities. The Company leverages recognized cybersecurity frameworks to organize, improve, and assess its cybersecurity program and to manage and reduce cybersecurity risk. The global information security team, under the direction of the CISO, develops, implements, and manages cybersecurity-related internal controls and risk processes for the Company, with internal controls consisting of a mix of administrative, technical, and physical controls. We deploy, configure, and maintain numerous technologies to enforce security policies, detect and protect against cybersecurity threats, and help safeguard the Company’s information systems and assets. We operate a Security Operation Center (“SOC”) to monitor cybersecurity threats, coordinate incident response resources, and reduce response times. Our internal SOC team is augmented by a third-party managed security services provider. The Company maintains a cybersecurity incident response plan that provides a structured approach for the Company’s response to cybersecurity incidents. Under the plan, cybersecurity incidents are escalated based on a defined incident severity scale, including to the Board of Directors as appropriate. To improve preparedness for a cybersecurity incident, we conduct tabletop exercises multiple times throughout the year. These exercises are conducted by internal team members and in some instances with assistance from third-party experts. The Company’s cybersecurity program also includes regular cybersecurity trainings for staff. We actively evaluate the training effectiveness and adjust the trainings based on the evaluations. The Company’s cybersecurity program is periodically reviewed and adjusted by the CISO's office so that it can remain flexible and responsive as circumstances evolve, new cybersecurity threats emerge, and regulations change. Engagement of Third Parties We engage third-party cybersecurity consultants and experts to supplement staffing of our SOC as well as to assess, validate, and enhance our security practices, including conducting cybersecurity maturity assessments, vulnerability assessments, and penetration tests. As part of the incident response process described above, we engage third-party experts as needed to support the incident response team, such as external legal advisors, cybersecurity forensic firms, and other specialists. Third Party Service Provider Risk Management Vendor risk assessment is part of the Company’s cybersecurity program, which facilitates management of third-party service providers’ IT-related risks. Third-party service providers that have access to the Company’s network, data and information are subject to a cybersecurity due diligence process and the corresponding security contractual and control requirements based on the nature of the engagement. The vendor risk assessment process is reviewed at least annually. Risks from Material Cybersecurity Threats Cybersecurity risk and the failure to maintain the integrity of our operational or security systems or infrastructure, or those of third parties with which we do business, could have a material adverse effect on our business, consolidated financial condition, results of operations, or cash flows.
