保険引受業務における AI
Insurance underwriting evaluates information about a policy or exposure.
このガイドを聴くAIによるナレーション · ~2 min
概要
This guide uses named examples documented by Progressive and Zurich, a simplified expected-loss illustration, and NAIC guidance on insurer responsibility for AI systems.
ディープダイブ
In a simplified example, expected loss is claim probability multiplied by claim severity; actual insurance pricing and underwriting depend on product, jurisdiction and additional factors. Progressive documents telematics signals such as time of day, hard braking or acceleration, and amount driven. Zurich and Nearmap describe aerial imagery that provides property and roof-condition or maintenance indicators. NAIC guidance says insurer decisions made or supported by AI must comply with applicable insurance laws and describes governance and risk-management expectations. A variable correlated with a protected trait can be a proxy risk worth testing, but correlation alone does not prove discrimination. SHAP attributes a prediction to model inputs; it does not establish causality or fairness.

保険引受業務における AI の未来
Evaluate the actual data, decision process and subgroup outcomes for each product. Prescription, credit, motor-vehicle and location data are jurisdiction- and product-specific and should not be treated as universal practice without direct evidence.

よくある質問
保険引受業務における AI とは何ですか?
Insurance underwriting evaluates information about a policy or exposure. This guide uses named examples documented by Progressive and Zurich, a simplified expected-loss illustration, and NAIC guidance on insurer responsibility for AI systems.
In a simplified hypothetical risk model, how is expected loss for one exposure calculated?
Expected loss is the probability-weighted average claim amount in this simplified example. It is a basic modeling definition, not a claim about every insurer’s production pricing formula.
Why might a regulated insurer document model inputs and validation?
NAIC’s AI guidance discusses governance, risk management, documentation and oversight. This does not imply that one model family is universally preferred for regulated underwriting.
Under the NAIC model bulletin, who remains responsible for AI-supported insurance decisions complying with applicable law?
The NAIC model bulletin places responsibility on the insurer using an AI system to ensure decisions comply with applicable laws. This is guidance context, not a statement that one rule applies identically in every jurisdiction.
What fairness risk should be tested when a model uses variables correlated with protected traits?
NAIC’s AI guidance highlights governance and unfair discrimination risks. A correlated variable can be a concern to evaluate; ZIP code is not asserted here to be a universal proxy in every product.
In an underwriting model, what is a feature?
A feature is a model input. Feature attribution methods such as SHAP describe how inputs contribute to a model prediction, but do not prove causation.
