Article 1 

1. Competent authorities carrying out annual assessments of the quality of the internal approaches of institutions in accordance with Article 78(3) of Directive 2013/36/EU shall share those assessments with all other relevant competent authorities and the European Banking Authority (EBA) within three months after the circulation of the report produced by EBA referred to in the second subparagraph of Article 78(3) of that Directive.
2. Upon receipt of the assessments referred to in paragraph 1, EBA shall share them with the relevant competent authorities responsible for the supervision of institutions belonging to a group subject to consolidated supervision where the competent authorities that prepared those assessments have not already done so.
Article 2 
When sharing assessments made in accordance with Article 78(3) of Directive 2013/36/EU, competent authorities shall provide the following information:

((a)) the conclusions and rationale of their assessment, based on the application of the assessment standards referred to in Articles 3 to 11;
((b)) their views on the level of potential underestimation of own fund requirements stemming from the internal approaches used by institutions.
Article 3 

1. When carrying out the assessment referred to in the first subparagraph of Article 78(3) or Directive 2013/36/EU, competent authorities shall identify the internal approaches that need specific assessment in a manner which is proportionate to the nature, scale and complexity of the risks inherent in the business model as well as the relevance of the portfolios included in Implementing Regulation (EU) 2016/2070 for the institution in relation to the risk profile of the institution. They shall also take into account the analysis provided in the EBA report referred to in the second subparagraph of Article 78(3) of Directive 2013/36/EU as follows:
(a) they shall treat values resulting from modelling which are considered as extreme in the EBA report as an indication of significant differences in own funds requirements in accordance with the first subparagraph of Article 78(3) of Directive 2013/36/EU;
(b) they shall treat values resulting from modelling and the standard deviation of those values for exposures in the same benchmark portfolio or similar benchmarking portfolios identified in the EBA report as a preliminary indication of significant differences and low or high diversity, as applicable, in own funds requirements in accordance with the first subparagraph of Article 78(3) of Directive 2013/36/EU;
(c) they shall treat potential differences computed in accordance with Article 4 of this Regulation as a preliminary indication of significant and systematic underestimation of own funds requirements in accordance with the first subparagraph of Article 78(3) of Directive 2013/36/EU;
(d) they shall treat potential differences between estimated risk parameters reported by the institutions under Implementing Regulation (EU) 2016/2070 and the historically observed risk parameters (‘outturns’) reported by the institutions in accordance with that Implementing Regulation as a preliminary indication of significant differences in own funds requirements in accordance with the first subparagraph of Article 78(3) of Directive 2013/36/EU;
(e) they shall treat potential differences between the own funds requirements for credit risk as reported by the institutions under Implementing Regulation (EU) 2016/2070 and the own funds requirements for credit risk that result from the use of outturns by the institutions in accordance with that Implementing Regulation or computed by EBA in its report referred to in the second subparagraph of Article 78(3) of Directive 2013/36/EU as a preliminary indication of significant and systematic underestimation of own funds requirements in accordance with the first subparagraph of Article 78(3) of that Directive. When using the report provided by EBA, competent authorities may take into account possible data limitations and reflect this in their assessment as deemed appropriate.
2. When carrying out the assessment referred to in paragraph 1 of this Article, competent authorities shall apply the assessment standards referred to in Articles 6 to 11.
Article 4 

1. Competent authorities shall compute the potential differences referred to in point (c) of Article 3(1) by subtracting the own funds requirements for credit risk as reported by the institutions under Implementing Regulation (EU) 2016/2070 from the own funds requirements for credit risk that result from the application of the standardised approach. In addition, they shall calculate the benchmark statistics regarding those differences as follows:
(a) for low-default portfolios (LDPs), at the portfolio level excluding the exposures to Member States' central government and central banks denominated and funded in the domestic currency as referred to in Article 114(4) of Regulation (EU) No 575/2013;
(b) for high-default portfolios (HDPs), at the portfolio level.
2. For the computation of benchmark statistics referred to in paragraph 1 of this Article, competent authorities shall use the own funds requirements for credit risk adjusted at the level applied for the computation of the transitional Basel I floor based on Article 500 of Regulation (EU) No 575/2013.
Article 5 
For the purposes of point (d) and (e) of Article 3(1), competent authorities shall use both one-year and five-year average outturns for computing the differences.
Article 6 

1. When carrying out the assessment referred to in Article 3(1) of this Regulation, competent authorities shall assess the compliance of institutions with the requirements of Implementing Regulation (EU) 2016/2070, where institutions have exercised the option of Article 3(2) of that Implementing Regulation in order to submit more limited reporting under that Implementing Regulation. Competent authorities shall do so by confirming the rationale and justification behind any limitations in the reporting that these institutions have provided under that Implementing Regulation.
2. When carrying out the assessment referred to in Article 3(1), competent authorities shall investigate the reasons for the significant and systematic underestimation and for the high or low diversity in the own funds requirements referred to in that paragraph, as follows:
(a) for assessments relating to credit risk approaches, by applying the standards referred to in Articles 7 and 8;
(b) for assessments relating to market risk approaches, by applying the standards referred to in Articles 9 to 11.
Article 7 

1. When carrying out an assessment referred to in Article 3(1) relating to credit risk approaches, competent authorities shall use at least the information on the internal approaches applied to the supervisory benchmarking portfolios which is contained in the following documents, where relevant:

(b) the institution's regular validation reports;
(c) model documentation including manuals, documentation on the development and calibration of the model and methodology for the internal approaches;
(d) reports regarding on-site visits.
2. When carrying out an assessment referred to in Article 3(1) relating to credit risk approaches, competent authorities shall take into account the following elements, where relevant:
(a) whether the institution uses own estimates of loss given default (LGD) and conversion factors in accordance with Article 143 of Regulation (EU) No 575/2013;
(b) the model's application perimeter and the representativeness of the benchmarking portfolios;
(c) key characteristics of the models such as distinguishing between models designed and calibrated at the centralised group level (global) and models designed and calibrated only at the level of the host jurisdiction (local), vendor and institution models, models developed and calibrated using internal data and models developed and calibrated using external data;

(f) the comparison of predicted downturn LGDs with observed LGDs;
(g) the comparison of estimated and observed exposures at default;
(h) the length of the time series used and, as applicable, the inclusion of distressed years or nature and materiality of any adjustment for capturing downturn conditions and adding margins of conservatism in the models' calibration;
(i) recent changes in the composition of the portfolio of the institution to which the internal approach is applied;
(j) the micro- and macroeconomic situation of the institution's portfolio, the risk and business strategy as well as internal process, such as recovery procedures for defaulted assets (‘workout procedures’);

Competent authorities shall collect the additional information in the way they deem to be most appropriate, including through questionnaires, interviews and ad hoc on-site visits.
Article 8 

1. When carrying out an assessment referred to in Article 3(1) relating to the LDP counterparties set out in template 101 of Annex I of Implementing Regulation (EU) 2016/2070, competent authorities shall assess whether the differences between the own funds requirements for credit risk of an institution and those of its peers are driven by any of the following:
(a) different rank ordering of the counterparties included in the LDP samples or different PD levels assigned to each grade;
(b) specific facility types, collateral instruments or location of the counterparties;
(c) heterogeneity in the PDs, LGDs, maturities or conversion factors;
(d) collateralisation practices;

Article 10 

1. When carrying out an assessment referred to in Article 3(1) relating to market risk approaches, competent authorities shall apply the standards set out in paragraphs 2 to 8 of this Article.
2. When assessing the causes of the differences for VaR values, competent authorities shall consider both of the following:
(a) any alternative homogenised VaR calculations that EBA may provide in its report referred to in the second subparagraph of Article 78(3) of Directive 2013/36/EU, using available profit-and-loss data;
(b) the dispersion observed in the VaR metric provided by institutions under Implementing Regulation (EU) 2016/2070.
3. For institutions using historical simulation, competent authorities shall assess the variability observed both in the alternative homogenised VaR calculations and in the VaR data reported by institutions referred to in paragraph 2, in order to determine the effect of the different options applied by those institutions within the historical simulation.
4. Competent authorities shall assess the dispersion among institutions in relation to particular risk factors included in each one of the non-aggregated benchmark portfolios using the observed volatility and the observed correlation in the profit-and-loss vector provided by institutions applying historical simulation for non-aggregated portfolios.
5. Competent authorities shall analyse VaR models of an institution for portfolios which might show a profit-and-loss time-series that significantly diverges from the profit-and-loss time-series of the institution's peers, as identified in the EBA report referred to in the second subparagraph of Article 78(3) of Directive 2013/36/EU, even where the final own funds requirement for that particular portfolio is similar to the one provided by the institution's peers in absolute terms.
6. In addition, for VaR, sVaR, IRC and models used for correlation trading activities, competent authorities shall assess the effect of regulatory variability drivers using the data provided by the EBA report referred to in the second subparagraph of Article 78(3) of Directive 2013/36/EU by clustering the metric outcomes by the different modelling options.
7. Once the causes of variability stemming from the different regulatory options have been assessed, competent authorities shall assess whether the remaining variability and underestimation of own funds requirements is driven by one or more of the following:
(a) misunderstandings regarding the positions or risk factors involved;
(b) incomplete model implementation;
(c) missing risk factors;
(d) differences in calibration or data series used in modelling simulation;
(e) additional risk factors incorporated in the model;
(f) alternative model assumptions applied;
(g) differences attributable to the methodology applied by the institution.
8. Competent authorities shall carry out a comparison between the outcomes obtained from portfolios, which only differ in a specific risk factor, to determine whether institutions have incorporated such a risk factor into their internal models consistently with their peer institutions.
Article 11 

1. Where assessing the level of own funds of each institution, competent authorities shall take into account both of the following:
(a) the level of own funds by non-aggregated portfolio;
(b) the effect of the diversification benefit applied by each institution in aggregated portfolios, by comparing the sum of own funds of the non-aggregated portfolios referred to in point (a) of this paragraph with the level of own funds provided for the aggregated portfolio, as provided in the EBA report referred to in the second subparagraph of Article 78(3) of Directive 2013/36/EU.
2. Where assessing the level of own funds by institution, competent authorities shall also take into account both of the following:
(a) the effect of the supervisory add-ons;
(b) the effect of the supervisory actions not contemplated in the data collected by EBA.
Article 12
