A waiver or other permission allowing the use of models in the calculation of PRR will be considered with regards to CAD and any VaR model permission which is granted will be considered with regards to CAD.4 Accordingly, the appropriate regulator is likely only to grant a waiver or other permission allowing the use of models in the calculation of PRR if it is a VaR model permission or a CAD 1 model waiver.
BIPRU 7.10 sets out the minimum standards that the appropriate regulator expects firms to meet before granting a VaR model permission. The appropriate regulator will not grant a VaR model permission unless it is satisfied that the requirements of BIPRU 7.10 are met and it is satisfied about the procedures in place at a firm to calculate the model PRR. In particular the appropriate regulator will not normally grant a VaR model permission unless it is satisfied about the quality
The appropriate regulator recognises that the nature of VaR models will vary between firms. The scope of and the requirements and conditions set out in a VaR model permission may therefore differ in substance or detail from BIPRU 7.10 in order to address individual circumstances adequately. The FCA will consider any differences by having regard to the CAD.4 A VaR model permission will implement any such variation by modifying BIPRU 7.10. A VaR model permission may also include
BIPRU 7.10.10GRP
Details of the general process for applying for a VaR model permission are set out in BIPRU 1.3 (Applications for advanced approaches). Because of the complexity of a VaR model permission, it is recommended that a firm discuss its proposed application with its usual contact at the appropriate regulator before it makes the application.
BIPRU 7.10.11GRP
In order for a VaR model permission to be granted, the appropriate regulator is likely to undertake a review to ensure that it is adequate and appropriate for the PRR calculation.
BIPRU 7.10.12GRP
The VaR model review process may be conducted through a series of visits covering various aspects of a firm's control and IT environment. Before these visits the appropriate regulator may ask the firm to provide some information relating to the firm'sVaR model permission request accompanied by some specified background material. The VaR model review visits are organised on a timetable that allows the firm being visited sufficient time to arrange the visit and provide the appropriate
BIPRU 7.10.15GRP
The appropriate regulator may complement its own review of a VaR model permission request with one or more reviews by a skilled person under section 166 of the Act (Reports by skilled persons). Such a review may also be used where a VaR model permission has been granted to ensure that the requirements BIPRU 7.10 and of the VaR model permission continue to be met.
3The stressed VaR measure must be based on inputs calibrated to historical data from a continuous twelve-month period of significant financial stress relevant to the firm's portfolio. The choice of that historical period will be subject to the appropriate regulator's approval and will form part of a firm'sVaR model permission.
BIPRU 7.10.37RRP
In aggregating VaR measures across risk or product categories, a firm must not use the square root of the sum of the squares approach unless the assumption of zero correlation between these categories is empirically justified. If correlations between risk categories are not empirically justified, the VaR measures for each category must simply be added in order to determine its aggregate VaR measure. But to the extent that a firm'sVaR model permission provides for a different way
3A firm with a VaR model permission must justify to the appropriate regulator any omissions of risk factors from its VaR model, if they are included in its pricing model.
BIPRU 7.10.45GRP
(1) This paragraph contains guidance on the inclusion of CIUs in a VaR model.(2) The appropriate regulator may allow all types of CIU to be included within the scope of a firm'sVaR model permission.(3) BIPRU 7.10 does not distinguish between specific risk and general market risk for positions in CIUs. Therefore even if specific risk is not otherwise included within the scope of a firm'sVaR model permission, a firm should be able to demonstrate that its VaR model captures specific
3As part of its VaR model permission, the appropriate regulator may authorise a firm to use the all price risk measure to calculate an additional capital charge in relation to positions in its correlation trading portfolio if it meets the following minimum standards:(1) it adequately captures all price risks at a 99.9% confidence interval over a capital horizon of one year under the assumption of a constant level of risk, and adjusted, where appropriate, to reflect the impact
BIPRU 7.10.102GRP
The appropriate regulator will review as part of a firm'sVaR model permission application the processes and documentation relating to the derivation of profit and loss used for backtesting. A firm's documentation should clearly set out the basis for cleaning profit and loss. To the extent that certain profit and loss elements are not updated every day (for example certain reserve calculations) the documentation should clearly set out how such elements are included in the profit
BIPRU 7.10.106GRP
(1) This paragraph gives guidance on the process for excluding backtesting exceptions as referred to in BIPRU 7.10.103R.(2) The appropriate regulator will respond flexibly to backtesting exceptions. However, the appropriate regulator's starting assumption will be that a backtesting exception should be taken into account for the purpose of the calculation of plus factors. If the firm believes that a backtesting exception should not count for that purpose, then it should seek a
BIPRU 7.10.110GRP
Where backtesting reveals severe problems with the basic integrity of the VaR model, the appropriate regulator may withdraw model recognition. In particular, if ten or more backtesting exceptions are recorded in a 250 business day period, the appropriate regulator may apply a plus factor greater than one or the appropriate regulator may consider revoking a firm'sVaR model permission. The appropriate regulator may also consider revoking a firm'sVaR model permission if ten or more
3The definition of hypothetical profit and loss figure may be amended or replaced in an individual VaR model permission if the firm can demonstrate to the appropriate regulator that the alternative method meets the spirit and purpose of the provisions in BIPRU 7.10 about the hypothetical profit and loss figure.
BIPRU 7.10.120GRP
The minimum multiplication factor, for VaR and stressed VaR,3 will never be less than three. If the appropriate regulator does set the minimum multiplication factor, for VaR and stressed VaR,3 above three the VaR model permission will have a table that sets out the reasons for that add on and specify how much of the add on is attributable to each reason (see BIPRU 7.10.121R). If there are weaknesses in the VaR model that may otherwise be considered a breach of the minimum standards
BIPRU 7.10.122GRP
Typically, any add on will be due to a specific weakness in systems and controls identified during the appropriate regulator's review that the appropriate regulator does not consider material enough to justify withholding overall model recognition. The firm will be expected to take action to address the reasons for any add on. The appropriate regulator will then review these periodically and, where satisfactory action has been taken, the add on will be removed through a variation
BIPRU 7.10.128GRP
A VaR model permission will contain requirements for what the firm should report to the appropriate regulator and the procedures for reporting. The precise requirements will vary from VaR model permission to VaR model permission. BIPRU 7.10.129R-BIPRU 7.10.130R set out what the appropriate regulator regards as the standard requirements.
BIPRU 7.10.129RRP
A firm must, no later than the number of business days after the end of each quarter specified in the VaR model permission for this purpose, submit, in respect of that quarter, a report to the appropriate regulator about the operation of the VaR model, the systems and controls relating to it and any changes to the VaR model and those systems and controls. Each report must outline as a minimum the following information in respect of that quarter:(1) methodological changes and developments
BIPRU 7.10.132GRP
The information in BIPRU 7.10.131G will vary over time. It is therefore not included in a VaR model permission as a rule but for information only. The appropriate regulator will update that information regularly in accordance with information supplied under BIPRU 7.10.129R. That updating will not amount to a variation of the VaR model permission.
BIPRU 7.10.134GRP
By modifying GENPRU 2.1.52 R (Calculation of the market risk capital requirement) to allow the firm to use the VaR model to calculate all or part of its PRR for certain positions, the appropriate regulator is treating it like an application rule. The modification means that the PRR calculation set out in BIPRU 7.10 supersedes the standard market risk PRR rules for products and risks coming within the scope of the VaR model permission.
BIPRU 7.10.147GRP
If a firm ceases to meet any of the requirements set out in BIPRU 7.10, the appropriate regulator's policy is that the VaR model permission should cease to have effect. In part this will be achieved by making it a condition of a firm'sVaR model permission that it complies at all times with the minimum standards referred to in BIPRU 7.10.26R - BIPRU 7.10.53R. Even if they are not formally included as conditions, the appropriate regulator is likely to consider revoking the VaR model
BIPRU 7.10.148RRP
If a firm ceases to meet the conditions or requirements in its VaR model permission or BIPRU 7.10 it must notify the appropriate regulator at once.
