Operational Risk

Overview

This calculator is the SCR Final Integrator for the Operational Risk suite within the Solvency II standard formula.^[1] It consumes the two feeder outputs from the Volume Measure calculator, consumes the Unit-Linked Expense add-on, applies the 30% BSCR cap, and returns SCRop plus the cap status indicator.

Input Terms

• Premium_Charge: Output from the Operational Risk Volume Measure calculator.
• Provision_Charge: Output from the Operational Risk Volume Measure calculator.
• UL_Expense_AddOn: Output from the Operational Risk Unit-Linked Expense calculator.
• BSCR: The Basic Solvency Capital Requirement, used to apply the regulatory 30% cap on operational risk capital.^[1]

Technical Rationale

The Operational Risk module follows a 99.5% confidence level over a one-year horizon. Unlike underwriting or market modules, operational risk is determined using a volume-based formula rather than a specific scenario-driven shock. This approach recognizes that operational failures (people, processes, or systems) scale with the complexity and size of the undertaking's business.^[1]

The calculation is split into three connected calculators. The Volume Measure calculator derives Premium_Charge and Provision_Charge from premiums and technical provisions. The Unit-Linked Expense calculator derives UL_Expense_AddOn as 25% of unit-linked administrative expenses. This SCR Final Integrator then selects the higher of Premium_Charge and Provision_Charge, applies the 30% BSCR cap, and adds UL_Expense_AddOn to produce SCRop.

Unit-linked life business is shown separately from the net life base. The life premium and life technical-provision legs use Life minus Unit-Linked values, while the unit-linked expense add-on is applied only in the specialist module. This prevents unit-linked exposure from being charged twice.

Important Notes

• BSCR Cap Binding: If the calculated operational charge exceeds 30% of the BSCR, the calculator automatically floors the result at the regulatory maximum. A binding cap indicates a high volume of operational activity relative to the diversified insurance risk.
• Feeder alignment: Premium_Charge and Provision_Charge should come from the same valuation date and perimeter as the BSCR used in the cap test.
• Gross vs. Net SCR: This calculator determines the standalone Operational Risk SCR. Operational risk is added to BSCR at the top SCR layer, and the undertaking's final net SCR is only finalized 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 feeding the S.25.01.01 standard-formula reporting view.^[3]
