An EGU Evaluation System Model To Assist Insurance Companies In Decision-Making During ExtremeWeather Events
Comprehensive AI Analysis for Insurance Risk Management
This study develops a comprehensive underwriting risk evaluation system (EGU) for insurance companies facing increased uncertainty from extreme weather events. Integrating the Z-score model, consistency detection, portfolio weighting, weighted TOPSIS, and ROC-Youden methods, it provides a robust cross-regional risk assessment. The model classifies countries into low-, medium-, and high-risk zones based on economic resilience, governance, and natural hazard exposure, offering a quantifiable basis for strategic decision-making in underwriting, risk pricing, and capital allocation.
Executive Impact & Key Findings
The EGU evaluation system provides critical insights for insurers to navigate climate-driven risks and optimize operational strategies.

Model Construction
The EGU system integrates various models: the Z-score model assesses insurer financial stability, while a three-tier EGU indicator system (Economic, Government, Uncontrollable factors) is validated for consistency. A combined weighting method (AHP, EWM, CVM) balances subjective and objective data for indicator weights. This ensures a robust, interpretable, and practical risk classification foundation.
Evaluation Methodology
The weighted TOPSIS model is used to calculate final risk scores, achieving unified quantification of multidimensional indicators. Subsequently, the ROC-Youden method determines optimal risk thresholds by maximizing the Youden index. This enhances the interpretability and practical applicability of classification results, providing a clear basis for risk-tiered underwriting decisions.
Results & Implications
The model demonstrates excellent discrimination (AUC = 1.00) with an optimal threshold of 0.0866. Countries like the US, Germany, and Japan are low-risk due to strong economic resilience and governance. India, Nigeria, and South Africa are medium-risk due to economic volatility or natural hazards. The framework provides a quantitative basis for regional deployment, risk pricing, and capital allocation.

Strategic Underwriting in Low-Risk Regions
In countries like the United States, characterized by high economic resilience and strong governance, insurance companies can pursue strategies focused on market expansion and optimizing product diversification. The lower overall risk level allows for competitive pricing and a higher concentration of capital allocation, maximizing returns while maintaining solvency.
The robust disaster response mechanisms and mature institutional frameworks in these regions significantly reduce the long-term claims volatility, making them attractive for stable, growth-oriented underwriting portfolios. Companies can leverage this stability to innovate in product offerings, such as parametric insurance solutions for specific extreme weather events.
Managing Underwriting in Moderate-Risk Regions
For regions such as India and Nigeria, classified as moderate risk due to economic volatility and natural hazards, a more cautious underwriting approach is warranted. Insurance companies should prioritize stricter risk controls, detailed localized hazard assessments, and potentially higher premium rates to compensate for elevated exposure.
Investment in local infrastructure and partnerships with government agencies for disaster preparedness can also contribute to mitigating risks. Capital allocation in these regions should be carefully managed, with an emphasis on diversified portfolios and robust reinsurance programs to buffer against potential large-scale losses from extreme weather events.
