Article 249
General treatment
In calculating risk-weighted exposure amounts for the securitised exposures, where the conditions in Article 244 are met, the originator institution of a synthetic securitisation shall, subject to Article 250, use the relevant calculation methodologies set out in this Section and not those set out in Chapter 2. For institutions calculating risk-weighted exposure amounts and expected loss amounts under Chapter 3, the expected loss amount in respect of such exposures shall be zero.
The requirements set out in the first subparagraph apply to the entire pool of exposures included in the securitisation. Subject to Article 250, the originator institution shall calculate risk-weighted exposure amounts in respect of all tranches in the securitisation in accordance with the provisions of this Section including those for which the institution recognises credit risk mitigation in accordance with Article 247, in which case the risk-weight to be applied to that position may be amended in accordance with Chapter 4, subject to the requirements laid down in this Chapter.
