AI Summary of Article 283 Permission to use the Internal Model Method

The competent authorities may authorise an institution to utilise the Internal Model Method (IMM) for calculating exposure values for specified transactions, provided the institution demonstrates compliance with established requirements. This includes a verification of robust counterparty credit risk (CCR) management systems.

Institutions are permitted to sequentially implement the IMM across transaction types, while still adhering to alternative methods for non-IMM transactions until full compliance is achieved. However, should an institution fail to maintain compliance, it must notify the authorities and either present a remedial plan or establish the immateriality of the non-compliance.

Article 283 Permission to use the Internal Model Method

1. Provided that the competent authorities are satisfied that the requirement in paragraph 2 have been met by an institution, they shall permit that institution to use the Internal Model Method (IMM) to calculate the exposure value for any of the following transactions:

(a) transactions in Article 273(2)(a);

(b) transactions in Article 273(2)(b), (c) and (d);

(c) transactions in Article 273(2)(a) to (d),

Where an institution is permitted to use the IMM to calculate exposure value for any of the transactions mentioned in points (a) to (c) of the first subparagraph, it may also use the IMM for the transactions in Article 273(2)(e).

Notwithstanding the third subparagraph of Article 273(1), an institution may choose not to apply this method to exposures that are immaterial in size and risk. In such case, an institution shall apply one of the methods set out in Sections 3 to 5 to these exposures where the relevant requirements for each approach are met.
