Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	The Cybersecurity Incident Response Team (“CIRT”), which provides technical expertise, and/or the Crisis Management Team (“CMT”), which focuses on business response, impact, business continuity and risk mitigation, work together and utilize a Cybersecurity Incident Response Plan (the “CIRP”) and the Playbook to: (1) prepare for and protect against Incidents; (2) detect and analyze Incidents; and (3) contain, eradicate and appropriately report on Incidents. In the event of an Incident, the CIRP provides a framework to coordinate the response. The CIRP and Playbook also address escalation protocols to senior management with respect to disclosure determinations related to an Incident and provides for Executive Team briefings as appropriate. If the CIRT’s initial investigation of the facts of an Incident indicates the need for escalation for potential disclosure, the CMT will utilize the process in the Playbook and the Cyber Disclosure Procedure may be utilized. The Playbook provides understandable and flexible processes for analyzing and responding to Incidents. In the event of an Incident, the Playbook provides predefined steps for response and escalation. The Cyber Disclosure Procedure establishes a flexible and context-dependent process for determining whether an Incident constitutes a material Incident pursuant to the rules and regulations of the SEC. A committee of senior management personnel is established to assess potential Incidents. Standing members of the Cyber Disclosure Committee (“CDC”) include the President and Chief Executive Officer, Chief Financial Officer, General Counsel, Global Privacy Officer and Chief Technology Officer. When evaluating the materiality of an Incident, the CDC considers both the quantitative and qualitative impacts, including the nature, extent and potential magnitude of the risks to the Company related to the Incident, particularly as it may relate to any compromised information or the scope of Company operations. If the CDC determines the Board should be notified, a meeting will be called with the Executive Committee of the Board, the Audit Committee Chair, the Board’s cybersecurity expert or any combination or subset of the foregoing. EIS conducts periodic cybersecurity evaluations of (i) critical third-party providers as risk dictates and (ii) significant new third-party providers prior to onboarding. EIS monitors and manages vulnerabilities in third-party environments through its vulnerability management program. This program aggregates findings from the vulnerability detection and secure configuration management tools within a dashboard, which allows EIS personnel to focus on high-priority matters. EIS maintains a range of security controls, including multi-factor authentication, internal and external penetration testing, cybersecurity assessments, benchmarking, annual employee security training, and social engineering testing. To detect and prevent Incidents, the cybersecurity program uses automated event-detection technology monitored by the cyber defense team, notifications from employees, vendors or service providers, and other tools. The Company has relationships with a number of third-party service providers to assist with Incident response and containment and remediation efforts, including a forensic investigation firm, insurance providers, auditors, consultants, assessors and various law firms. While the Company maintains a robust cybersecurity program, the techniques used to infiltrate information technology systems continue to evolve. Accordingly, the Company operates with, and plans for, the notion that it is impossible to prevent or detect all Incidents, that Incidents will occur, and that the Company will not always be able to detect threats in a timely manner or anticipate and implement adequate security measures. For additional information, see Item 1A. “Risks Related to the Company’s Information Technology, Cybersecurity and Data Protection.” The Company is not aware of any Incidents or threats during the past fiscal year that met the threshold for materiality under SEC rules. However, the Company and its customers routinely face risks of Incidents, as the Company relies heavily on its information technology systems. Although the Company makes efforts to maintain the security and integrity of the Company’s information technology systems, these systems and the proprietary, confidential internal and customer information that resides on or is transmitted through them are subject to the risk of Incidents or disruption, and there can be no assurance that the Company’s or its third-party providers’ security measures will prevent all breakdowns or Incidents affecting the Company’s or the Company’s third-party providers’ information security environments, software or systems that could adversely affect the Company’s business.
