Article 247
Calculation of risk-weighted exposure amounts
1.
Where an originator institution has transferred significant credit risk associated with the underlying exposures of the securitisation in accordance with Section 2, that institution may:
(a)
in the case of a traditional securitisation, exclude the underlying exposures from its calculation of risk-weighted exposure amounts, and, as relevant, expected loss amounts;
(b)
in the case of a synthetic securitisation, calculate risk-weighted exposure amounts, and, where relevant, expected loss amounts, with respect to the underlying exposures in accordance with Articles 251 and 252.
2.
Where the originator institution has decided to apply paragraph 1, it shall calculate the risk-weighted exposure amounts as set out in this Chapter for the positions that it may hold in the securitisation.
Where the originator institution has not transferred significant credit risk or has decided not to apply paragraph 1, it shall not be required to calculate risk-weighted exposure amounts for any position it may have in the securitisation but shall continue including the underlying exposures in its calculation of risk-weighted exposure amounts and, where relevant, expected loss amounts as if they had not been securitised.
3.
Where there is an exposure to positions in different tranches in a securitisation, the exposure to each tranche shall be considered a separate securitisation position. The providers of credit protection to securitisation positions shall be considered as holding positions in the securitisation. Securitisation positions shall include exposures to a securitisation arising from interest rate or currency derivative contracts that the institution has entered into with the transaction.
4.
Unless a securitisation position is deducted from Common Equity Tier 1 items pursuant to point (k) of Article 36(1), the risk-weighted exposure amount shall be included in the institution’s total of risk-weighted exposure amounts for the purposes of Article 92(3).
5.
The risk-weighted exposure amount of a securitisation position shall be calculated by multiplying the exposure value of the position, calculated as set out in Article 248, by the relevant total risk weight.
6.
The total risk weight shall be determined as the sum of the risk weight set out in this Chapter and any additional risk weight in accordance with Article 270a.
