Article 254
Hierarchy of methods
1.
Institutions shall use one of the methods set out in Subsection 3 to calculate risk-weighted exposure amounts in accordance with the following hierarchy:
(a)
where the conditions set out in Article 258 are met, an institution shall use the SEC-IRBA in accordance with Articles 259 and 260;
(b)
where the SEC-IRBA may not be used, an institution shall use the SEC-SA in accordance with Articles 261 and 262;
(c)
where the SEC-SA may not be used, an institution shall use the SEC-ERBA in accordance with Articles 263 and 264 for rated positions or positions in respect of which an inferred rating may be used.
2.
For rated positions or positions in respect of which an inferred rating may be used, an institution shall use the SEC-ERBA instead of the SEC-SA in each of the following cases:
(a)
where the application of the SEC-SA would result in a risk weight higher than 25 % for positions qualifying as positions in an STS securitisation;
(b)
where the application of the SEC-SA would result in a risk weight higher than 25 % or the application of the SEC-ERBA would result in a risk weight higher than 75 % for positions not qualifying as positions in an STS securitisation;
(c)
for securitisation transactions backed by pools of auto loans, auto leases and equipment leases.
3.
In cases not covered by paragraph 2, and by way of derogation from point (b) of paragraph 1, an institution may decide to apply the SEC-ERBA instead of the SEC-SA to all of its rated securitisation positions or positions in respect of which an inferred rating may be used.
For the purposes of the first subparagraph, an institution shall notify its decision to the competent authority no later than 17 November 2018.
Any subsequent decision to further change the approach applied to all of its rated securitisation positions shall be notified by the institution to its competent authority before the 15th November immediately following that decision.
In the absence of any objection by the competent authority by 15 December immediately following the deadline referred to in the second or third subparagraph, as appropriate, the decision notified by the institution shall take effect from 1 January of the following year and shall be valid until a subsequently notified decision comes into effect. An institution shall not use different approaches in the course of the same year.
4.
By way of derogation from paragraph 1, competent authorities may prohibit institutions, on a case by case basis, from applying the SEC-SA when the risk-weighted exposure amount resulting from the application of the SEC-SA is not commensurate to the risks posed to the institution or to financial stability, including but not limited to the credit risk embedded in the exposures underlying the securitisation. In the case of exposures not qualifying as positions in an STS securitisation, particular regard shall be had to securitisations with highly complex and risky features.
5.
Without prejudice to paragraph 1 of this Article, an institution may apply the Internal Assessment Approach to calculate risk-weighted exposure amounts in relation to an unrated position in an ABCP programme or ABCP transaction in accordance with Article 266, provided that the conditions set out in Article 265 are met. Where an institution has received permission to apply the Internal Assessment Approach in accordance with Article 265(2), and a specific position in an ABCP programme or ABCP transaction falls within the scope of application covered by such permission, the institution shall apply that approach to calculate the risk-weighted exposure amount of that position.
6.
For a position in a re-securitisation, institutions shall apply the SEC-SA in accordance with Article 261, with the modifications set out in Article 269.
7.
In all other cases, a risk weight of 1 250 % shall be assigned to securitisation positions.
8.
The competent authorities shall inform the EBA of any notification made pursuant to paragraph 3 of this Article. The EBA shall monitor the impact of this Article on capital requirements and the range of supervisory practices in connection with paragraph 4 of this Article, and shall report annually to the Commission on its findings and issue guidelines in accordance with Article 16 of Regulation (EU) No 1093/2010.
