Flood Grouped Sum Insured

1Step 1

Weight each flood group by the highest risk weight in that group

Weightedi=SumInsuredi×RiskWeightiWeighted_i=SumInsured_i\times RiskWeight_i

Sum weighted groups to produce the grouped sum insured simplification

Understand the Non-Life Flood Risk Grouping Simplification

Overview

Article 90b permits grouped natural catastrophe exposure data where the highest applicable risk weight is retained for each group.[1]

Input Terms

  • Flood Group Sum Insured: The sum insured for each flood exposure group used in the Article 90b natural catastrophe simplification.[1][2]
  • Flood Group Highest Risk Weight: The highest applicable flood risk weight assigned to the exposure group.[1][2]

Technical Rationale

For flood, the grouped exposure remains Article 123-compliant only when each group retains the highest applicable flood-zone weight.[2]

Important Notes

  • Grouping condition: The simplification should not understate flood exposure by combining zones with different risk weights unless the Article 90b highest-risk-weight rule is preserved.[1]
