Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | ​ Description of Processes for Assessing, Identifying and Managing Cybersecurity Risks ​ Vista’s system of internal controls includes consideration of cybersecurity risks. The Company uses technology and control procedures designed to mitigate cybersecurity risks, with our management team working to monitor, identify, assess, and respond to potential cybersecurity incidents that may threaten the Company. The system of controls also focuses on security awareness and training for employees and contractors with access to Company facilities or systems. Company management periodically reviews system and organization control reports (SOC 1, Type 2) for key outsourced information systems to ensure that third-party data processing is subject to appropriate controls and security measures. Cybersecurity risks for Vista include the potential for financial loss, loss of data, and business interruption. Vista maintains technology and non-technology-based system controls, a data backup program, and disaster recovery testing to mitigate these risks. ​ Our cybersecurity controls also follow defense in depth principles, which aim to implement various layered access control, detection, prevention, and response measures. We periodically engage with third parties to assess our vulnerabilities and help us mitigate cybersecurity-related risks.

Cybersecurity Risk Board of Directors Oversight [Text Block] | Board of Directors’ Oversight of Risks from Cybersecurity ​ Management, under supervision of the CEO and CFO, has developed a system of internal controls that identifies risks to the Company, designed controls intended to reduce risks to an appropriately low level, implemented control procedures, and subsequently tested such control procedures. Management presents an enterprise risk management assessment to the Audit Committee on a quarterly basis and provides the Audit Committee with frequent updates of specific financial statement risks. Risks associated with cybersecurity are included in these risk assessments, subjected to testing of key controls, and reflected in management’s reports to the Audit Committee. The Board of Directors receives periodic briefings on selected risk matters, and is invited to participate in each Audit Committee meeting and, as such, is provided with the same information presented to the Audit Committee.
