Article 236a 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.
