All material aspects of the rating and estimation processes must be approved by the firm'sgoverning body or a designated committee thereof and senior management. These parties must possess a general understanding of the firm'srating systems and detailed comprehension of its associated management reports.[Note: BCD Annex VII Part 4 point 124]
(1) A firm'sgoverning body or designated committee may choose to approve only material aspects of the firm'srating systems and material changes to the firm'srating systems.(2) Where a firm'sgoverning body or designated committee chooses to approve only material aspects of the firm'srating systems and material changes to the firm'srating systems:(a) the firm'sgoverning body or designated committee should define the firm's overall approach to material aspects of rating and estimation
Where the firm'srating systems are used on a unified basis for the parent undertaking and its subsidiary undertakings under BIPRU 4.2.3 R, and approval and reporting of the ratings systems are carried out at the group level, the governance requirements in BIPRU 4.3.9 R and BIPRU 4.3.11 R may be met if:(1) the subsidiary undertakings have delegated to the governing body or designated committee of the EEA parent institution or EEA parent financial holding company responsibility
Senior management must have a good understanding of the rating system's designs and operations. Senior management must ensure on an ongoing basis that the rating systems are operating properly. Senior management must be regularly informed by the credit risk control units about the performance of the rating process, areas needing improvement, and the status of efforts to improve previously identified deficiencies.[Note:BCD Annex VII Part 4 point 126]
The credit risk control unit must be independent from the personnel and management functions responsible for originating or renewing exposures and report directly to senior management. The unit must be responsible for the design or selection, implementation, oversight and performance of the rating systems. It must regularly produce and analyse reports on the output of the rating systems.[Note:BCD Annex VII Part 4 point 128]
The areas of responsibility for the credit risk control unit(s) must include the following:(1) testing and monitoring grades and pools;(2) production and analysis of summary reports from the firm'srating systems;(3) implementing procedures to verify that grade and pool definitions are consistently applied across departments and geographic areas;(4) reviewing and documenting any changes to the rating process, including the reasons for the changes;(5) reviewing the rating criteria
Notwithstanding BIPRU 4.3.16 R, a firm using pooled data according to BIPRU 4.3.92 R - BIPRU 4.3.94 R (Overall requirements for estimation) may outsource the following tasks:(1) production of information relevant to testing and monitoring grades and pools;(2) production of summary reports from the firm'srating systems;(3) production of information relevant to review of the rating criteria to evaluate if they remain predictive of risk;(4) documentation of changes to the rating
A firm must document the design and operational details of its rating systems. The documentation must evidence compliance with the minimum IRB standards and the firm'sIRB permission, and address topics including portfolio differentiation, rating criteria, responsibilities of parties that rate obligors and exposures, frequency of assignment reviews, and management oversight of the rating process.[Note:BCD Annex VII Part 4 point 31]
A firm must ensure that all documentation relating to its rating systems or otherwise required by the rules governing the IRB approach are stored, arranged and indexed in such a way that the firm would be able to make them all available to the FSA, or to make any class or description of them specified by the FSA available to the FSA, immediately on demand or within a short time thereafter.
A rating system comprises all of the methods, processes, controls, data collection and IT systems that support the assessment of credit risk, the assignment of exposures to grades or pools (rating), and the quantification of default and loss estimates for a certain type of exposure.[Note:BCD Annex VII Part 4 point 1]
A firm must have robust systems in place to validate the accuracy and consistency of rating systems, processes, and the estimation of all relevant risk parameters (PD, LGD, conversion factors and EL). A firm must be able to demonstrate to the FSA that the internal validation process enables it to assess the performance of internal rating and risk estimation systems consistently and meaningfully.[Note:BCD Annex VII Part 4 point 110]
(1) A firm must validate its rating systems. Its validation process must include, as a minimum, the elements set out in (2) - (8).(2) A firm must establish and define standards of objectivity, accuracy, stability and conservatism that it designs its ratings systems to meet. It must have processes that establish whether its rating systems meet those standards.(3) A firm must establish and define standards of accuracy of calibration (i.e. whether outcomes are consistent with estimate)
(1) This paragraph sets out guidance on assessing the adequacy of a rating system's discriminative power (see BIPRU 4.3.30 R (3) on the meaning of discriminative power).(2) A firm should be able to explain the performance of its rating systems against its chosen measure (or measures) of discriminative power. In making this comparison a firm should rely primarily on actual historic default experience where this is available. In particular, a firm should be able to explain:(a) the
A firm must also use other appropriate quantitative validation tools and comparisons with relevant external data sources. The analysis must be based on data that is appropriate to the portfolio, is updated regularly, and covers a relevant observation period. A firm's internal assessments of the performance of its rating systems must be based on as long a period as possible.[Note:BCD Annex VII Part 4 point 112]
Internal audit or another comparable independent auditing unit must review at least annually the firm'srating systems and its operations, including the operations of the firm and the estimation of PDs, LGDs, ELs and conversion factors. Areas of review must include adherence to all applicable minimum requirements.[Note:BCD Annex VII Part 4 point 131]
The grade or pool definitions and criteria must be sufficiently detailed to allow those charged with assigning ratings consistently to assign obligors or facilities posing similar risk to the same grade or pool. This consistency must exist across lines of business, departments and geographic locations within each rating system.[Note:BCD Annex VII Part 4 point 17 (part)]
(1) This paragraph contains guidance on BIPRU 4.3.43 R and more general guidance about the governance of rating systems.(2) In determining the assignment referred to in BIPRU 4.3.43 R, a firm should have regard to the sensitivity of the rating to movements in fundamental risk drivers.(3) A firm should, for any rating system, be able to demonstrate that it acts appropriately or has an appropriate policy, as applicable, with respect to:(a) any deficiencies caused by its not being
For grade and pool assignments a firm must document the situations in which human judgement may override the inputs or outputs of the assignment process and the personnel responsible for approving these overrides. A firm must document these overrides and the personnel responsible. A firm must analyse the performance of the exposures whose assignments have been overridden. This analysis must include assessment of the performance of exposures whose rating has been overridden by
(1) This paragraph applies to the use of statistical models and/or other mechanical methods to assign exposures to obligor grades, obligor pools, facility grades or facility pools.(2) A firm must be able to demonstrate to the FSA that the model has good predictive power and that capital requirements are not distorted as a result of its use.(3) The input variables to the model must form a reasonable and effective basis for the resulting predictions. The model must not have material
(1) This paragraph contains guidance on BIPRU 4.3.51 R (7).(2) BIPRU 4.3.51 R (7) does not require that each individual assignment of an exposure to a pool or grade should be the subject of an open-ended review by reference to factors not covered by the model if:(a) that is not necessary in order to meet the requirements of BIPRU 4 about the ability of the rating system to predict and to discriminate (as referred to in BIPRU 4.3.29 R to BIPRU 4.3.30 R (Validation of internal estimates));
A firm should ensure that IT systems relevant to the operation of its rating systems are sound and robust. A firm's IT systems should provide rapid availability of databases and appropriate archiving. Adequate controls should be in place to prevent unauthorised changes to data being made. Contingency processes and plans should be in place to deal with events of system failure. A firm should document work-flows and procedures related to data collection and storage.
A firm should be able to demonstrate to the FSA:(1) how, with respect to each rating system, both assignment of ratings and estimates of PD, LGD and conversion factors are affected by:(a) movements in the economic cycle; and(b) other cyclical effects which are material to levels of default, loss or the amount of exposures at default for the exposures covered by the rating system; and(2) the level of conservatism inherent in its ratings, as provided for by BIPRU.
Estimation of PD through the use of a technique set out in BIPRU does not remove the need to make conservative adjustments, where necessary, related to the expected range of estimation errors so that capital requirements produced by the relevant model or other rating system are not understated.
If a firm uses data that is pooled across institutions it must be able to demonstrate to the FSA that:(1) the rating systems and criteria of other firms in the pool are similar to its own;(2) the pool is representative of the portfolio for which the pooled data is used; and(3) the pooled data is used consistently over time by the firm for its permanent estimates.2[Note:BCD Annex VII Part 4 point 57]
If a firm uses data that is pooled across institutions it remains responsible for the integrity of its rating systems. If a firm uses such data it must be able to demonstrate to the FSA that it has sufficient in-house understanding of its rating systems, including effective ability to monitor and audit the rating process.[Note:BCD Annex VII Part 4 point 58]
(1) If:(a) a firm's internal experience of exposures of a type covered by a model or other rating system is 20 defaults or fewer; and(b) in the firm's view, reliable estimates of PD cannot be derived from external sources of default data, including the use of market price related data, for all the exposures covered by the rating system;the firm must estimate PD for exposures covered by that rating system in accordance with this rule.(2) A firm must use a statistical technique
A firm must use LGD estimates that are appropriate for an economic downturn if those are more conservative than the long-run average. To the extent a rating system is expected to deliver constant realised LGDs by grade or pool over time, a firm must make adjustments to its estimates of risk parameters by grade or pool to limit the capital impact of an economic downturn.[Note:BCD Annex VII Part 4 point 74]
A firm must use conversion factor estimates that are appropriate for an economic downturn if those are more conservative than the long-run average. To the extent a rating system is expected to deliver realised conversion factors at a constant level by grade or pool over time, a firm must make adjustments to its estimates of risk parameters by grade or pool to limit the capital impact of an economic downturn.[Note:BCD Annex VII Part 4 point 88]
A firm's systems for the management and rating of credit risk exposures must be sound and implemented with integrity and, in particular, they must meet the following standards in accordance with the minimum IRB standards:(1) the firm'srating systems provide for a meaningful assessment of obligor and transaction characteristics, a meaningful differentiation of risk and accurate and consistent quantitative estimates of risk;(2) internal ratings and default and loss estimates used
(1) This guidance sets out the basis on which a firm may rely upon a rating system or data provided by another member of its group.(2) A firm may rely upon a rating system or data provided by another member of its group if the following conditions are satisfied:(a) the firm only does so to the extent that it is appropriate, given the nature and scale of the firm's business and portfolios and the firm's position within the group;(b) the group is an EEA banking and investment group;(c)
(1) This paragraph provides guidance on BIPRU 4.2.2 R and in particular BIPRU 4.2.2 R (1).(2) The information that a firm produces or uses for the purpose of the IRB approach should be reliable and take proper account of the different users of the information produced (customers, shareholders, regulators and other market participants).(3) A firm should establish quantified and documented targets and standards, against which it should test the accuracy of data used in its rating
This paragraph provides further guidance on BIPRU 4.2.2 R and in particular BIPRU 4.2.2 R (2). In the FSA's view risk management has an essential role in informing risk decisions. However, an essential role does not necessarily mean an exclusive role or even always a primary role. There may be justifiable differences between the IRB approach and the firm's use of rating systems for its internal purposes as referred to in BIPRU 4.2.2 R (2). For example, internal standards and policies
A firm must be able to demonstrate that it has been using for the IRB exposure classes in question rating systems that were broadly in line with the minimum IRB standards for internal risk measurement and management purposes for at least three years prior to the date of its IRB permission.[Note:BCD Article 84(3)]
In meeting the experience requirement under BIPRU 4.2.11 R, the FSA would expect a firm to be able to demonstrate that it has been:(1) operating an internal rating system with estimates of PD;(2) meeting the standards in BIPRU 4 for senior management knowledge and reporting; and(3) meeting the standards in BIPRU 4 relating to the use of rating systems in its business;for the required minimum 3 year period.
In meeting the experience requirement under BIPRU 4.2.13 R, the FSA would expect a firm to be able to demonstrate that it has been:(1) operating an internal rating system with estimates of LGD and with conversion factors; and(2) compliant with BIPRU 4.2.11 R as applied to the advanced IRB approach.for the required minimum 3 year period.
(1) To the extent that its IRB permission permits this, a firm permitted to use the IRB approach in the calculation of risk weighted exposure amounts and expected loss amounts3 for one or more IRB exposure classes may apply the standardised approach in accordance with this rule.3(2) A firm may apply the standardised approach to the IRB exposure class referred to in BIPRU 4.3.2 R (1) (Sovereigns) where the number of material counterparties is limited and it would be unduly burdensome
An obligor grade means for the purpose of BIPRU 4 as it applies to the sovereign, institution and corporate IRB exposure class a risk category within a rating system's obligor rating scale, to which obligors are assigned on the basis of a specified and distinct set of rating criteria, from which estimates of PD are derived. A firm must document both the relationship between obligor grades in terms of the level of default risk each grade implies and the criteria used to distinguish
In addition to complying with the material in BIPRU 4.3.54 R (Data maintenance) a firm must collect and store:(1) complete rating histories on obligors and recognised guarantors;(2) the dates the ratings were assigned;(3) the key data and methodology used to derive the rating;(4) the person responsible for the rating assignment;(5) the identity of obligors and exposures that defaulted;(6) the date and circumstances of such defaults;(7) data on the PDs and realised default rates
To the extent that a firm uses data on internal default experience for the estimation of PDs it must be able to demonstrate in its analysis that the estimates are reflective of underwriting standards and of any differences in the rating system that generated the data and the current rating system. Where underwriting standards or rating systems have changed, a firm must add a greater margin of conservatism in its estimate of PD.[Note:BCD Annex VII Part 4 point 63]
1A facility grade means for the purpose of the advanced IRB approach a risk category within a rating system's facility scale to which exposures are assigned on the basis of a specified and distinct set of rating criteria from which own estimates of LGDs are derived. The grade definition must include both a description of how exposures are assigned to the grade and of the criteria used to distinguish the level of risk across grades.[Note:BCD Annex VII Part 4 point 10]
(1) The FSA will only grant an IRB permission if it is satisfied that the firm's systems for the management and rating of credit risk exposures are sound and implemented with integrity and, in particular, that they meet the standards in BIPRU 4.2.2 R in accordance with the minimum IRB standards.(2) Under BIPRU 4.2.11 R, a firm applying for an IRB permission is required to demonstrate that it has been using for the IRB exposure classes in question rating systems that were broadly
An IRB permission will set out firm-specific material. This will generally include:(1) details about the firm's methodology for carrying out the IRB approach, including the models and rating systems that a firm should use;(2) reporting requirements; and(3) requirements about internal control structure.
In addition to complying with BIPRU 4.3.54 R (Data maintenance) a firm must collect and store:(1) data used in the process of allocating exposures to grades or pools;(2) data on the estimated PDs, LGDs and conversion factors associated with grades or pools of exposures;(3) the identity of obligors and exposures that defaulted;(4) for defaultedexposures, data on the grades or pools to which the exposure was assigned over the year prior to default and the realised outcomes on LGD
(1) If a firm applies for an IRB permission or for a variation of an IRB permission that permits the treatment in BIPRU 4.5.10 R it should demonstrate that its standards exceed those of the slotting criteria provided for in BIPRU 4.5 and result in ratings that are stronger than the benchmarks referred to in (3).(2) If a firm has an IRB permission that permits the treatment in BIPRU 4.5.10 R it should continue to be able to demonstrate the matters in (1) to the FSA if asked.(3)
A firm calculating risk weighted exposure amounts in accordance with the IRB approach must disclose the following information:(1) the scope of the firm'sIRB permission;(2) an explanation and review of:(a) the structure of internal rating systems and relation between internal and external ratings;(b) the use of internal estimates other than for calculating risk weighted exposure amounts in accordance with the IRB approach;(c) the process for managing and recognising credit risk
The governance arrangements that apply to the governing body, the senior management and any designated committee of a firm in relation to the IRB approach or the AMA also apply to the body or persons with equivalent powers with respect to the UK consolidation group or non-EEA sub-group. Where the parent undertaking and its subsidiary undertakings use rating systems on a unified basis, the approval and reporting process described in BIPRU 4.3.12 G (Approval and reporting arrangements
