AI Summary of Article 261 Calculation of risk-weighted exposure amounts under the Standardised Approach (SEC-SA)

This summary addresses the risk-weighted exposure calculations for securitisation positions under the SEC-SA framework. It mandates that institutions multiply the exposure value of a securitisation position by an appropriate risk weight, which is subject to a minimum floor of 15%. The risk weight is determined by the proportion of underlying exposures that are in default, defined by specific delinquency conditions.

Furthermore, institutions may apply an inferred risk weight to derivative positions linked to securitisation, reflecting the risk weight of the corresponding reference position. Should the delinquency status for more than 5% of underlying exposures remain unknown, a higher risk weight of 1,250% applies to the securitisation position, underscoring the critical importance of comprehensive exposure assessments.

Article 261 Calculation of risk-weighted exposure amounts under the Standardised Approach (SEC-SA)

1. Under the SEC-SA, the risk-weighted exposure amount for a position in a securitisation shall be calculated by multiplying the exposure value of the position as calculated in accordance with Article 248 by the applicable risk weight determined as follows, in all cases subject to a floor of 15 %:

where:

2. For the purposes of paragraph 1, KA shall be calculated as follows:

where:

(a) the sum of the nominal amount of underlying exposures in default, to

(b) the sum of the nominal amount of all underlying exposures.

For these purposes, an exposure in default shall mean an underlying exposure which is either: (i) 90 days or more past due; (ii) subject to bankruptcy or insolvency proceedings; (iii) subject to foreclosure or similar proceeding; or (iv) in default in accordance with the securitisation documentation.
