Catastrophe Scenario Brief

A structured brief for catastrophe risk scenarios, exposure, vulnerability, financial terms, and uncertainty.

1. Decision and peril

State the management decision and the peril or hazard in scope.

2. Event representation

Define whether the analysis uses historical events, synthetic events, return-period concepts, deterministic stresses, or another scenario set.

3. Exposure quality

Assess geocoding, insured values, construction, occupancy, policy terms, missing fields, and concentration.

4. Vulnerability

Document damage or loss assumptions and their relationship to event intensity and insured characteristics.

5. Financial terms

Specify deductibles, limits, layers, attachment points, occurrence/aggregate terms, and reinsurance as relevant.

6. Uncertainty

Present alternative assumptions, data limitations, model limitations, and ranges separately from any central estimate.

Important: The correct actuarial, legal, regulatory, privacy, security, accounting, or other specialist review depends on the actual use case and jurisdiction.
