Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
We have a global cybersecurity program designed to identify, protect, detect, respond to and recover from cybersecurity risks and threats. We regularly assess risks from cybersecurity and technology threats and monitor our information systems for potential vulnerabilities. We use a widely-adopted risk quantification model to identify, measure and prioritize cybersecurity and technology risks and develop related security controls and safeguards. We conduct regular reviews and tests of our cybersecurity program and also leverage audits by our internal audit team, penetration and vulnerability testing and other exercises to evaluate the effectiveness of our cybersecurity program and improve our security measures and planning.
Cybersecurity education is a priority for our employees and business partners. Employees complete cybersecurity training to help identify and respond to potential cybersecurity risks and reinforce safe behaviors. We also impose security requirements upon our third-party services and software providers, including: maintaining an effective security management program; abiding by information handling and asset management requirements; and notifying us in the event of any known or suspected cyber incident; however, we rely on such third parties to implement security programs commensurate with their risk, and their efforts may not be successful.
We have experienced targeted and non-targeted cybersecurity attacks and incidents in the past and we could in the future experience similar attacks. To date, no cybersecurity incident or attack, or any risk from cybersecurity threats, has materially affected or has been determined to be reasonably likely to materially affect the Company or our business strategy, results of operations, or financial condition.
