A model risk manager is creating a materiality threshold for AI model risk classification. Which factor MOST justifies classifying an AI model as 'high materiality'?
Select an answer to reveal the explanation.
Short Explanation
Here's the deal — b is correct because materiality in model risk is primarily driven by the consequence of model errors, not model complexity alone. A model that directly drives binding credit, pricing, or underwriting decisions affecting customers at scale has high materiality because errors propagate directly into consequential outcomes.
Full Explanation
B is correct because materiality in model risk is primarily driven by the consequence of model errors, not model complexity alone. A model that directly drives binding credit, pricing, or underwriting decisions affecting customers at scale has high materiality because errors propagate directly into consequential outcomes. Complexity (A) is a factor in validation difficulty but not in materiality. Vendor source (C) is a third-party risk factor. Lack of recent validation (D) is a governance control deficiency that may increase risk but is not what determines inherent materiality.
