Residual risk exposure (A) is the most important factor to emphasize because senior management is responsible for accepting or rejecting risk on behalf of the organization. CISM guidance stresses that executives are less concerned with technical details and more focused on what risk remains after controls are applied and whether it exceeds risk appetite. Threat details (B), architectural gaps (C), and industry breaches (D) can provide context, but they do not directly answer the key governance question: What level of risk does the organization still face? Presenting residual risk enables informed decision-making about whether additional controls are justified.
