A change in the risk profile would be the most important information to communicate to stakeholders after an annual risk assessment is completed, as it indicates how the risk landscape of the organization has changed over time, and how it affects the achievement of the business goals and objectives. A decrease in threats, an increase in reported vulnerabilities, and an increase in identified risk scenarios are also important information, but they are not the most important, as they are specific aspects of the risk profile, and do not provide a holistic view of the risk exposure and appetite of the organization. References = CRISC Review Manual, 7th Edition, page 109.
