The purpose of BIPRU 7.9 is to provide guidance on the appropriate regulator's policy for granting CAD 1 model waivers under section 138A of the Act (Modification or waiver of rules). The policy recognises that CAD 1 models may vary across firms but, as a minimum, the appropriate regulator will need to be satisfied:(1) about the quality of the internal controls and risk management relating to the model (see BIPRU 7.9.19G - BIPRU 7.9.23G for further details);(2) about the quality

The output and how it is used in the PRR calculation

Depending on the type of model and the requirements in the CAD 1 model waiver granted, the outputs from an options risk aggregation model are used as an input to the market risk capital requirement calculation.

Depending on the type of model and the requirements in the CAD 1 model waiver granted, the individual sensitivity figures produced by this type of CAD 1 model are either input into the calculation of interest rate PRR under the interest rate duration method (see BIPRU 7.2.63R) or are converted into notional position and input into the calculation of interest rate PRR under the interest rate maturity method (see BIPRU 7.2.59R).

A review by a skilled person may be used before a CAD 1 model waiver is granted to supplement the waiver process or after the waiver has been granted to review the CAD 1 model.
No changes should be made to a CAD 1 model unless the change is not material. Material changes to a CAD 1 model will require a renewed waiver to be issued. Materiality is measured from the time that the waiver is granted or, if the waiver has been varied in accordance with section 138A of the Act, any later time that may be specified in the waiver for these purposes. If a firm is considering making material changes to its CAD 1 model, then it should notify the appropriate regulator
(1) A firm should have a conceptually sound risk management system which is implemented with integrity and should meet the minimum standards set out in this paragraph.(2) A firm should have a risk control unit that is independent of business trading units and reports directly to senior management. The unit should be responsible for designing and implementing the firm's risk management system. It should produce and analyse daily reports on the risks run by the business and on the
In using the scenario matrix approach, none of the steps followed will take specific account of a firm's exposure to rho risk. Where a firm can demonstrate that for interest rate-related options the rho sensitivity is effectively included in the delta sensitivities produced, there is no separate capital requirement relating to rho. For all other options except commodity options, a firm should calculate a rho sensitivity ladder by currency using its CAD 1 model and either feed
