La structure de données comprend également un modèle de données de facteur de risque qui contient des données représentant des facteurs de risque utilisés pour déterminer un risque de base pour au moins un des actifs critiques. La structure de données comprend en outre un modèle de données de risque central contenant des données de risque central pour déterminer un risque central pour l'actif critique en utilisant le risque de base pour l'actif critique.
