Article 401

Description
Calculating the effect of the use of credit risk mitigation techniques
Main content

1. For calculating the value of exposures for the purposes of Article 395(1) an institution may use the “fully adjusted exposure value” as calculated under Part Three, Title II, Chapter 4 taking into account the credit risk mitigation, volatility adjustments, and any maturity mismatch (E*).

2. An institution permitted to use own estimates of LGDs and conversion factors for an exposure class under Part Three, Title II, Chapter 3 may, subject to a permission by the competent authorities recognise the effects of financial collateral in calculating the value of exposures for the purposes of Article 395(1).

Competent authorities shall grant the permission referred to in preceding subparagraph only if the institution can estimate the effects of financial collateral on their exposures separately from other LGD-relevant aspects.

The estimates produced by the institution shall be sufficiently suitable for reducing the exposure value for the purposes of compliance with the provisions of Article 395.

Where an institution is permitted to use its own estimates of the effects of financial collateral, it shall do so on a basis consistent with the approach adopted in the calculation of the own funds requirements in accordance with this Regulation.

Institutions permitted to use own estimates of LGDs and conversion factors for an exposure class under Part Three, Title II, Chapter 3, which do not calculate the value of their exposures using the method referred to in the first subparagraph of this paragraph, may use the Financial Collateral Comprehensive Method or the approach set out in Article 403(1)(b) for calculating the value of exposures.

3. An institution that makes use of the Financial Collateral Comprehensive Method or is permitted to use the method described in paragraph 2 of this Article in calculating the value of exposures for the purposes of Article 395(1) shall conduct periodic stress tests of their credit-risk concentrations, including in relation to the realisable value of any collateral taken.

These periodic stress tests referred to in the first subparagraph shall address risks arising from potential changes in market conditions that could adversely impact the institutions' adequacy of own funds and risks arising from the realisation of collateral in stressed situations.

The stress tests carried out shall be adequate and appropriate for the assessment of such risks.

In the event that the periodic stress test indicates a lower realisable value of collateral taken than would be permitted to be taken into account while making use of the Financial Collateral Comprehensive Method or the method described in paragraph 2 as appropriate, the value of collateral permitted to be recognised in calculating the value of exposures for the purposes of Article 395(1) shall be reduced accordingly.

Institutions referred to in the first subparagraph shall include the following in their strategies to address concentration risk:

(a) policies and procedures to address risks arising from maturity mismatches between exposures and any credit protection on those exposures;

(b) policies and procedures in the event that a stress test indicates a lower realisable value of collateral than taken into account while making use of the Financial Collateral Comprehensive Method or the method described in paragraph 2;

(c) policies and procedures relating to concentration risk arising from the application of credit risk mitigation techniques, and in particular large indirect credit exposures, for example to a single issuer of securities taken as collateral.
