Article 401
Calculating the effect of the use of credit risk mitigation techniques
1.
For calculating the value of exposures for the purposes of Article 395(1), an institution may use the fully adjusted exposure value (E*) as calculated under Chapter 4 of Title II of Part Three, taking into account the credit risk mitigation, volatility adjustments and any maturity mismatch referred to in that Chapter.
2.
With the exception of institutions using the Financial Collateral Simple Method, for the purposes of the first paragraph, institutions shall use the Financial Collateral Comprehensive Method, regardless of the method used for calculating the own funds requirements for credit risk.
By way of derogation from paragraph 1, institutions with permission to use the methods referred to in Section 4 of Chapter 4 of Title II of Part Three and Section 6 of Chapter 6 of Title II of Part Three, may use those methods for calculating the exposure value of securities financing transactions.
3.
In calculating the value of exposures for the purposes of Article 395(1), institutions shall conduct periodic stress tests of their credit-risk concentrations, including in relation to the realisable value of any collateral taken.
The 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 those risks.
Institutions shall include the following in their strategies to address concentration risk:
(a)
(b)
policies and procedures relating to concentration risk arising from the application of credit risk mitigation techniques, in particular from large indirect credit exposures, for example, exposures to a single issuer of securities taken as collateral.
4.
Where an institution reduces an exposure to a client using an eligible credit risk mitigation technique in accordance with Article 399(1), the institution, in the manner set out in Article 403, shall treat the part of the exposure by which the exposure to the client has been reduced as having been incurred for the protection provider rather than for the client.
