1. This Decision specifies the criteria for the delegation of decision-making powers to the heads of work units of the ECB for the adoption of certain decisions on material changes or extensions to rating systems.
2. The delegation of decision-making powers is without prejudice to the supervisory assessment to be performed for the purposes of taking decisions granting permission for an early implementation of material changes or extensions to rating systems and decisions granting permission to implement material changes or extensions to rating systems after an investigation.
Delegation of decisions on prior permission to implement material changes or extensions to rating systems
1. In accordance with Article 4 of Decision (EU) 2017/933 (ECB/2016/40), the Governing Council hereby delegates to the heads of work units nominated by the Executive Board in accordance with Article 5 of that Decision the power to adopt decisions granting permission for an early implementation of material changes or extensions to rating systems which fulfil the delegation criteria set out in Article 4.
2. In accordance with Article 4 of Decision (EU) 2017/933 (ECB/2016/40), the Governing Council hereby delegates to the heads of work units nominated by the Executive Board in accordance with Article 5 of that Decision the power to adopt decisions granting permission to implement material changes or extensions to rating systems after an investigation which fulfil the criteria set out in Article 5.
3. Decisions referred to in paragraphs 1 and 2 shall not be adopted by means of a delegated decision if the supervisory assessment of those decisions has a direct impact on the supervisory assessment of another decision which is to be adopted under the non-objection procedure, or the complexity of the assessment or the sensitivity of the matter require that they are adopted under the non-objection procedure following a dedicated supervisory assessment.
4. Negative decisions on early implementation of material changes or extensions to rating systems and negative decisions on material changes or extensions to rating systems after an investigation shall not be adopted by means of a delegated decision.
Criteria for the adoption of delegated decisions on early implementation of material changes or extensions to rating systems
1. Decisions granting permission for an early implementation of material changes or extensions to rating systems shall be taken by means of a delegated decision if all of the following criteria are met:
(a)
the application package is complete;
(b)
the application package includes a review or an assessment of the application conducted by the supervised entity’s internal validation function or internal audit function which concludes that:
(i)
the material change to a rating system as described in the self-assessment questionnaire completed by the supervised entity fulfils the relevant requirements namely that no material deficiencies leading to a material change to a rating system have been detected; and
(ii)
obligations from past ECB decisions related to the rating system in scope of the application are fulfilled;
(c)
the supervised entity agrees in writing in the application to apply a limitation, in the form of a floor to its capital requirements as further specified in paragraphs 2 or 3, as applicable;
(d)
the supervised entity agrees in writing that it is ready to implement the proposed material change or extension within three months after the date of notification of the decision granting the permission.
2. Where a material change is requested, the floor referred to in paragraph 1, point (c), is applied to all exposures belonging to the range of application of the rating system for which the material change permission is requested. The floor is applied at the highest level of consolidation within participating Member States.
3. The floor applies to the ratio between the risk-weighted exposure amount and the underlying exposure value, and is calculated as the higher of:
(a)
the risk weight calculated using the rating system including the material change;
(b)
0,98 times the risk weight determined under paragraph 5.
4. Where a material extension is requested, the floor referred to in paragraph 1 is determined and applied separately at the level of each additional business unit, additional type of product or obligor, or additional exposures related to the lending decision of a third party to the group, to which the range of application of each rating system is requested to be extended. The floor is applied to the ratio between the risk-weighted exposure amount and the underlying exposure value, and is calculated as the higher of:
(a)
the risk weight calculated for the full rating system, including the business unit for which the material extension is requested;
(b)
the risk weight determined under paragraph 6.
5. For the purposes of the calculation of the floor described in paragraph 3, the supervised entity informs the ECB, as part of the application package, of the ratio between the risk-weighted exposure amount and the underlying exposure value for each rating system for which the material change is requested at the end of the last quarter preceding the date of submission of the application package to the ECB.
6. For the purposes of the calculation of the floor described in paragraph 4, the supervised entity, at the end of the last quarter preceding the submission of the application package to the ECB and as part of the application package, informs the ECB of the ratio between the risk-weighted exposure amount and the underlying exposure value for each additional business unit, additional type of product or obligor, or additional exposures related to the lending decision of a third party to the group, to which the range of application of each rating system is requested to be extended, according to the calculation method used for the additional exposures prior to the extension.
7. Where the application package consists of both a material change and a material extension on the scope of a rating system, the limitation applied by the supervised entity on that scope will be the higher of the floors determined under paragraphs 3 and 4.
Criteria for the adoption of delegated decisions on material changes or extensions to rating systems after an investigation
1. Decisions granting permission to implement material changes or extensions to rating systems after an investigation shall be taken by means of a delegated decision if all of the following criteria are met:
(a)
the proposed material change or extension has received a positive assessment from the ECB;
(b)
the Common Equity Tier 1 capital ratio at consolidated level of the supervised entity, after implementation of the proposed material change or extension to the rating system, does not increase or decrease by more than 20 basis points measured at the level of the range of application of the relevant rating system;
(c)
the decision does not impose limitations or conditions;
(d)
where the decision imposes obligations, the supervised entity has agreed in writing to those obligations in advance, and the obligations comply with all of the following:
(i)
where relevant, the obligations require the supervised entity to improve its rating systems, the use of the IRB Approach, the rating and exposure assignment process, the calculation of risk-weighted exposure amounts and loss exposure amounts, data and documentation, risk quantification, default detection, IT infrastructure or credit risk mitigation techniques in accordance with Part Three, Title II, Chapters 3 and 4, of Regulation (EU) No 575/2013, as required by the relevant regulatory technical standards and interpreted in accordance with the relevant European Banking Authority guidelines and ECB Guides;
(ii)
where relevant, the obligations require the supervised entity to improve its governance, control or validation activities in accordance with Part Three, Title II, Chapters 3 and 4, of Regulation (EU) No 575/2013, as required by the relevant regulatory technical standards and interpreted in accordance with the relevant European Banking Authority guidelines and ECB Guides;
(iii)
the obligations set deadlines of a minimum of 3 months and a maximum of 36 months.
2. The criteria set out in paragraph 1 shall also apply where the application package consists both of a material change and a material extension.
