Document Overview
AI Summary of Article 236a Calculating risk-weighted exposure amounts and expected loss amounts under the substitution approach where the guaranteed exposure is treated under the IRB Approach using own estimates of LGD and a comparable direct exposure to the protection provider is treated under the IRB Approach
This document outlines the regulatory framework for institutions applying the Internal Ratings-Based (IRB) Approach to exposures with unfunded credit protection. Institutions are mandated to determine the covered part of the exposure based on the lower of the exposure value and the adjusted value of the unfunded credit protection. The risk-weighted exposure amount and expected loss calculations must align with the institution's estimates for comparable direct exposures to the protection provider.
Additionally, where applicable, institutions must apply the appropriate loss given default (LGD) and risk weight functions, ensuring compliance with regulations governing maturity calculations. The treatment of any uncovered parts of the exposure must adhere to relevant adjustments related to credit risk, further ensuring regulatory fidelity.

Article 236a Calculating risk-weighted exposure amounts and expected loss amounts under the substitution approach where the guaranteed exposure is treated under the IRB Approach using own estimates of LGD and a comparable direct exposure to the protection provider is treated under the IRB Approach
1. For an exposure with unfunded credit protection to which an institution applies the IRB Approach set out in Chapter 3 using its own estimates of LGD and where comparable direct exposures to the protection provider are treated under the IRB Approach set out in Chapter 3, but without using its own estimates of LGD, the institution shall determine the covered part of the exposure as the lower of the exposure value (E) and the adjusted value of the unfunded credit protection (GA), calculated in accordance with Article 235a(1). The institution shall calculate the risk-weighted exposure amount and the expected loss amount for the covered part of the exposure value by using the PD, the LGD and the same risk weight function as the ones used for a comparable direct exposure to the protection provider, and shall, where applicable, use the maturity (M) related to the underlying exposure, calculated in accordance with Article 162.
