Understand the Non-Life Windstorm Region Risk

Non-Life Windstorm Region Risk

Article 121 defines windstorm risk through region-specific loss amounts built from zone weighted sums insured and zone correlations.[1] This regional calculation establishes the Windstorm Region SCR for the selected Annex V region before the Article 121 regional aggregation step.

Inputs

  • Annex V Region: The windstorm region being calculated. The selected region preserves traceability to the Article 121 regional aggregation basis.
  • Windstorm Zone Inputs: Each zone input selects an Annex IX zone and one zone WSI amount. Non-Life Windstorm Zone WSI provides the calculation path from sums insured, risk weights, and any lower amount cap.
  • Zone Correlations: Zone-pair coefficients are deduced from Annex XXII for the selected region and selected zones. They are Article 121 legal parameters rather than independent assumptions.

Calculation

The specified windstorm loss is calculated from the zone weighted sums insured and the Annex XXII zone correlations.

Article 121 applies the gross event-sequence factor to the specified loss. For windstorm, the two Article 121 event sequences both sum to 120% of the specified loss before reinsurance and SPV recoveries. Because this page does not model recoveries event by event, it displays the result as a gross event-sequence uplift, not as separate scenario losses.

Important Notes

The Windstorm Region SCR output is the regional amount used in the Article 121 windstorm-risk aggregation. This page models the gross regional formula path. It does not calculate how reinsurance contracts or special purpose vehicles respond to the ordered event sequence; that would require a separate reinsurance-aware event model.

  • Gross vs. Net SCR: This calculator determines the standalone Non-Life Windstorm Region Risk SCR. Solvency II risk is only finalized as a net impact on Basic Own Funds after diversification in Non-Life Risk, then within BSCR, and after the top-level LAC TP and LAC DT adjustments.
  • Regulatory deviation: Material deviation from standard-formula assumptions at this layer may support a capital add-on or a move toward an internal model where justified.[2]
  • Reporting: The displayed result is intended to support the corresponding standard-formula component for the S.25.01.01 standard-formula reporting view.[3]
