A key risk indicator (KRI) is a metric that provides information on the level of exposure to a given risk.
Changes in risk trend data indicate that the likelihood or probability of a risk occurring has changed.
Therefore, the frequency of risk occurrence should be updated in the risk register to reflect the current risk profile. The impact, cost, and legal aspects of risk realization are not directly affected by the changes in risk trend data, unless the nature or severity of the risk has also changed.
