Life Disability-Morbidity Risk

Overview

This calculator implements the gross capital requirement for the Life Disability-Morbidity Risk sub-module within the Solvency II standard formula.^[1] The Life Disability-Morbidity Risk requirement is defined as the economic capital necessary to cover the loss in basic own funds resulting from a 1-in-200 year stress event affecting inception and recovery rates for disability and morbidity obligations.^[2]

Input Terms

• Basic Own Funds (Pre-Stress): The undertaking's basic own funds before the application of the disability shocks.
• Scenario Shock (Assets/Liabilities): The instantaneous change in the value of assets and technical provisions resulting from the prescribed disability and recovery rate shocks.^[1]
• LAC TP / LACDT (Scenario-Specific): The reduction in the gross scenario loss provided by the loss-absorbing capacity of technical provisions and deferred taxes.

Technical Rationale

The Life Disability-Morbidity Risk sub-module is calibrated to a 99.5% confidence level over a one-year horizon. It captures the sensitivity of the undertaking’s basic own funds to an adverse increase in disability inception rates and a decrease in recovery rates for policies where health-related events are a risk driver (e.g., income protection or disability cover).^[1]

The calculation follows a stressed-own-funds approach, measuring the capital requirement as the reduction in net asset value (NAV) after applying several scenarios, including high-intensity first-year inception shocks (35%) and persistent long-term increases (25%), alongside a 20% decrease in recovery rates. This method ensures that the requirement reflects the real economic loss after claims, reserves, and potential tax offsets have all reacted to the change in disability assumptions. The final result represents the gross disability underwriting component before diversification in Life Risk.

Important Notes

• Morbidity Sensitivity Bound: Only policies that are sensitive to a disability or morbidity event are included in the shock. The module covers risks relating to sickness, disability, and medical expenses when managed under life technical provisions.^[3]
• Inception vs. Recovery: For many portfolios, the recovery-rate shock (decrease in people returning to health) is the binding driver, leading to higher long-term payouts even if the initial number of disability claims remains stable.
• Gross vs. Net SCR: This calculator determines the standalone Life Disability-Morbidity Risk SCR on the visible stressed basis. Even where the page already reflects direct own-funds or tax effects, Solvency II risk is only finalized as a net impact on Basic Own Funds after diversification in Life Risk, then within BSCR, and after the top-level LAC TP and LACDT 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.^[4]
• Reporting: The displayed result is intended to support the corresponding standard-formula component feeding the S.25.01 standard-formula reporting view.^[5]
