Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Air Group’s management and Board consider cybersecurity to be a critical component of the Company’s risk management plan. Our systems are subject to increasing and evolving cybersecurity risks. Unauthorized parties have attempted and continue to attempt to gain access to our systems and information, including through fraudulent misrepresentation and other means of deception. The systems of our suppliers, vendors, and other business partners are also at risk. The threat of cybersecurity incidents is included within our company’s annual Enterprise Risk Management (ERM) program that assesses the most significant risks to the enterprise. Because of the industry in which we operate, we are subject to extensive cybersecurity regulation, including but not limited to those regulations overseen by the FAA, TSA, and DOT. As a result, it is imperative our cybersecurity risk management is well-planned and sufficiently robust to maintain compliance with these regulations. As part of our annual review of our cybersecurity risk management, we engage third-parties for a variety of processes including external audits, vulnerability assessments, and penetration tests. These processes help ensure our overarching strategy remains effective over time.
