The risk weighted exposure amounts for credit risk for exposures belonging to one of the exposure classes referred to in (1) to (4) must, unless deducted from capital resources, be calculated in accordance with the following provisions:(1) for exposures in the sovereign, institution and corporate IRB exposure class, BIPRU 4.4.57 R to BIPRU 4.4.60 R, BIPRU 4.4.79 R, BIPRU 4.5.8 R to BIPRU 4.5.10 R (for specialised lending exposures), BIPRU 4.9.3 R and BIPRU 4.8.16 R to BIPRU 4.8.17
The calculation of risk weighted exposure amounts for credit risk and dilution risk must be based on the relevant parameters associated with the exposure in question. These include probability of default (PD), loss given default (LGD), maturity (M) and the exposure value of the exposure. PD and LGD may be considered separately or jointly, in accordance with the provisions relating to PD and LGD in BIPRU 4.4, BIPRU 4.6, BIPRU 4.7 and BIPRU 4.8 at:(1) for exposures in the sovereign,
The expected loss amounts for exposures belonging to one of the IRB exposure classes referred to in (1) to (3) must be calculated in accordance with the methods set out in the following provisions:(1) for exposures in the sovereign, institution and corporate IRB exposure class, BIPRU 4.4.61 R to BIPRU 4.4.62 R and (for specialised lending exposures) BIPRU 4.5.13 R to BIPRU 4.5.15R;(2) for exposures in the retail exposure class, BIPRU 4.6.47 R to BIPRU 4.6.48 R;(3) for exposures
The calculation of expected loss amounts in accordance with BIPRU 4.3.6 R must be based on the same input figures of PD, LGD and the exposure value for each exposure as being used for the calculation of risk weighted exposure amounts in accordance with BIPRU 4. For defaultedexposures,where a firm uses its own estimate of LGDs, EL must be the firm's best estimate of expected loss (ELBE), for the defaultedexposure in accordance with BIPRU 4.3.122 R.[Note:BCD Article 88(2)]
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 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]
(1) A firm must regularly perform a credit risk stress test to assess the effect of certain specific conditions on its total capital requirements for credit risk. The test to be employed must be one chosen by the firm. The test to be employed must be meaningful and reasonably conservative. Stressed portfolios must contain the vast majority of a firm's total exposures covered by the IRB approach.(2) The stress test must be designed to assess the firm's ability to meet its capital
A firm must take all relevant information into account in assigning obligors and facilities to grades or pools. Information must be current and must enable the firm to forecast the future performance of the exposure. The less information a firm has, the more conservative must be its assignments of exposures to obligor and facility grades or pools. If a firm uses an external rating as a primary factor determining an internal rating assignment, the firm must ensure that it considers
(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
The following provisions also apply with respect to the definition of default:(1) for overdrafts, days past due commence once an obligor has breached an advised limit, has been advised a limit smaller than current outstandings, or has drawn credit without authorisation and the underlying amount is material;(2) an advised limit means a limit which has been brought to the knowledge of the obligor;(3) days past due for credit cards commence on the minimum payment due date;(4) in
(1) Elements to be taken as indications of unlikeliness to pay must include the items set out in this rule.(2) The firm putting the credit obligation on non-accrued status must be taken as an indication of unlikeliness to pay.(3) The firm making a value adjustment resulting from a significant perceived decline in credit quality subsequent to the firm taking on the exposure must be taken as an indication of unlikeliness to pay.(4) The firm selling the credit obligation at a material
If a firm considers that a previously defaultedexposure is such that no trigger of default continues to apply, the firm must rate the obligor or facility as it would for a non-defaultedexposure. Should the definition of default subsequently be triggered, another default must be deemed to have occurred.[Note:BCD Annex VII Part 4 point 47]
For the specific case of exposures already in default, a firm must use the sum of its best estimate of expected loss for each exposure given current economic circumstances and exposure status and the possibility of additional unexpected losses during the recovery period.[Note:BCD Annex VII Part 4 point 80]
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
(1) This rule, in accordance with BIPRU 4.3.57 R (4) (Definition of default), sets the exact number of days past due that a firm should abide by in the case of exposures to PSEs.(2) For counterparts that are PSEs situated within the United Kingdom the number of days past due is 180.(3) For counterparts that are PSEs situated in another EEA State the number of days past due is the lower of:(a) 180; and(b) the number of days past due fixed under the CRD implementation measure with
A firm must use the following LGD values:(1) senior exposures without eligible collateral, 45%;(2) subordinated exposures without eligible collateral, 75%;(3) a firm may recognise funded and unfunded credit protection in the LGD in accordance with BIPRU 5 (Credit risk mitigation), as modified by BIPRU 4.10;(4) covered bonds may be assigned an LGD value of 12.5%; and(5) for certain senior corporate exposure purchased receivables, for certain subordinated corporate exposure purchased
(1) The exposure value for the items set out in this rule must be calculated as the committed but undrawn amount multiplied by the applicable conversion factor set out in this rule.(2) For credit lines which are uncommitted, that are unconditionally cancellable at any time by the firm without prior notice, or that effectively provide for automatic cancellation due to deterioration in a borrower's credit worthiness, a conversion factor of 0 % applies. To apply a conversion factor
1Notwithstanding BIPRU 4.4.34 R and BIPRU 4.8.25 R, if a firm'sIRB permission permits it to use own LGD estimates under the advanced IRB approach for exposures to which BIPRU 4 applies and permits it to use the approach in this rule, unfunded credit protection may be recognised by adjusting PD and/or LGD estimates subject to the minimum IRB standards. A firm must not assign guaranteed exposures an adjusted PD or LGD such that the adjusted risk weight would be lower than that of
1If a firm uses its own estimates of conversion factors under the advanced IRB approach it must calculate the exposure value of off-balance sheet exposures calculated with the use of conversion factors by using its own estimates of conversion factors across different product types as mentioned in BIPRU 4.4.37 R and BIPRU 4.4.39 R (2) to BIPRU 4.4.39 R (4).[Note:BCD Annex VII Part 3 point 9 (part)]
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]
1For a firm permitted to use own estimates of LGDs or conversion factors under the advanced IRB approach, each exposure must be assigned to a facility grade as part of the credit approval process. This is in addition to the requirements in BIPRU 4.4.11 R - BIPRU 4.4.13 R.[Note:BCD Annex VII Part 4 point 20]
1As well as complying with BIPRU 4.3.54 R and BIPRU 4.4.21 R (Data maintenance), a firm using own estimates of LGDs and/or conversion factors under the advanced IRB approach must collect and store:(1) complete histories of data on the facility ratings and LGD and conversion factor estimates associated with each rating scale3;(2) the dates the ratings were assigned and the estimates were done;(3) the key data and methodology used to derive the facility ratings and LGD and conversion

In addition to BIPRU 5.8.2 R, where there is a maturity mismatch the credit protection must not be recognised where the exposure is a short term exposure specified in the firm'sIRB permission as being subject to a one-day floor rather than a one-year floor in respect of the maturity value (M) under BIPRU 4.4.68 R.[Note: BCD Annex VIII Part 4 point 2(b)]
Notwithstanding BIPRU 4.3.5 R (Relevant parameters), the calculation of risk weighted exposure amounts for credit risk for all exposures belonging to the equity exposureIRB exposure class must be calculated in accordance with one of the following ways:(1) the simple risk weight approach (see BIPRU 4.7.8 R;(2) the PD/LGD approach (see BIPRU 4.7.13 R); and(3) the internal models approach (see BIPRU 4.7.23 R);in accordance with BIPRU 4.7 and subject to the firm'sIRB permission.[Note:BCD
The expected loss amounts1 for equity exposures must be calculated according to the following formula:(1) expected loss amount = EL × exposure value; and(2) the EL values must be the following:(a) expected loss (EL) = 0.8% for private equity exposures in sufficiently diversified portfolios;(b) expected loss (EL) = 0.8% for exchange traded equity exposures; and(c) expected loss (EL) = 2.4% for all other equity exposures.[Note:BCD Annex VII Part 1 point 32]
The risk weighted exposure amounts must be calculated according to the formulas in BIPRU 4.4.58 R (Risk weighted exposure amounts for sovereigns, institutions and corporates). If a firm does not have sufficient information to use the definition of default a scaling factor of 1.5 must be assigned to the risk weights.[Note:BCD Annex VII Part 1 point 22]
A firm may recognise unfunded credit protection obtained on an equity exposure in accordance with the methods set out in BIPRU 5 (Credit risk mitigation) as modified by BIPRU 4.10. This must be subject to an LGD of 90% on the exposure to the provider of the hedge. For private equity exposures in sufficiently diversified portfolios an LGD of 65% may be used.[Note:BCD Annex VII Part 1 point 24]
PDs must be determined according to the methods for corporate exposures. The following minimum PDs must be applied:(1) 0.09% for exchange traded equity exposures where the investment is part of a long-term customer relationship;(2) 0.09% for non-exchange traded equity exposures where the returns on the investment are based on regular and periodic cash flows not derived from capital gains;(3) 0.40% for exchange traded equity exposures including other short positions as set out
The risk weighted exposure amount is the potential loss on the firm'sequity exposures as derived using internal value-at-risk models subject to the 99th percentile, one-tailed confidence interval of the difference between quarterly returns and an appropriate risk-free rate computed over a long-term sample period, multiplied by 12.5.

The data used must
A firm must have sound internal standards for situations where comparison of actual equity exposure returns with the models' estimates calls the validity of the estimates or of the models as such into question. These standards must take account of business cycles and similar systematic variability in equity exposure returns. All adjustments made to internal models in response to model reviews must be documented and consistent with the firm's model review standards.[Note:BCD Annex
To be eligible to be treated as a retail exposure, exposures must meet the following criteria:(1) they must be either to an individual person or persons, or to a small or medium sized entity, provided in the latter case that the total amount owed to the firm and parent undertaking and its subsidiary undertakings, including any past due exposure, by the obligor client or group of connected clients, but excluding claims or contingent claims secured on residential real estate collateral,
(1) A firm must consider the following risk drivers when assigning exposures to grades or pools:(a) obligor risk characteristics;(b) transaction risk characteristics, including product or collateral types or both; and(c) delinquency.(2) In the case of (1)(b) a firm must explicitly address cases where several exposures benefit from the same collateral.(3) However:(a) a firm need not consider delinquency if this is compatible with its IRB permission; and(b) (in the case of a firm
A firm must at least annually update obligor and facility assignments or review the loss characteristics and delinquency status of each identified risk pool whichever is applicable. A firm must also at least annually review in a representative sample the status of individual exposures within each pool as a means of ensuring that exposures continue to be assigned to the correct pool.[Note:BCD Annex VII Part 4 point 29]
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

For these exposures the number is 90 days.(3) For retail exposures to counterparts situated in another EEA State the number of days past due is the
If a firm derives long run average estimates of PD and LGD for retail exposures from an estimate of total losses, and an appropriate estimate of PD or LGD, the process for estimating total losses must meet the minimum IRB standards1 for estimation of PD and LGD, and the outcome must be consistent with the concept of LGD as set out in BIPRU 4.3.99 R (Default weighted average).[Note:BCD Annex VII Part 4 point 70]
(1) For qualifying revolving retail exposures a correlation (R) of 0.04 must replace the correlation formula in the table in BIPRU 4.6.42 R.(2) Retail exposures qualify as qualifying revolving retail exposures if they meet the following conditions:(a) the IRB permission of the firm in question does not disapply this paragraph;(b) the exposures are to individuals;(c) the exposures are revolving, unsecured, and, to the extent they are not drawn, immediately and unconditionally cancellable
Unfunded credit protection may be recognised as eligible by adjusting PD or LGD estimates subject to the minimum IRB standards as specified in BIPRU 4.10.43 R - BIPRU 4.10.48 R and in accordance with the IRB permission either in support of an individual exposure or a pool of exposures. A firm must not assign guaranteed exposures an adjusted PD or LGD such that the adjusted risk weight would be lower than that of a comparable, direct exposure to the guarantor.[Note:BCD Annex VII
If a firm derives long run average estimates of PDs and LGDs for corporate exposure purchased receivables from an estimate of EL, and an appropriate estimate of PD or LGD, the process for estimating total losses must meet the overall standards for estimation of PD and LGD set out in the minimum IRB standards,2 and the outcome must be consistent with the concept of LGD as set out in BIPRU 4.3.99 R.[Note: BCD Annex VII Part 4 point 61]
For its corporate exposure purchased receivables a firm must comply with the minimum requirements set out in BIPRU 4.8.11 R - BIPRU 4.8.15 R. For corporate exposure purchased receivables that comply in addition with the conditions set out in BIPRU 4.8.18 R, and where it would be unduly burdensome for a firm to use the risk quantification standards for corporate exposures as set out in the minimum IRB standards for these receivables, the risk quantification standards for retail
For corporate exposure purchased receivables, refundable purchase discounts, collateral or partial guarantees that provide first-loss protection for defaultlosses, dilution losses, or both, may be treated as first-loss positions under the provisions in BIPRU 9 (Securitisation) about the IRB approach.[Note: BCD Annex VII Part 1 point 8]
With respect to retail exposures, for purchased receivables, refundable purchase discounts, collateral or partial guarantees that provide first-loss protection for defaultlosses, dilution losses, or both, may be treated as first-loss positions under the provisions in BIPRU 9 (Securitisation) about the IRB approach.[Note: BCD Annex VII Part 1 point 15]
The risk weights for dilution risk for purchased receivables (both corporate exposures and retail exposures) must be calculated according to this rule. The risk weights must be calculated according to the formula in BIPRU 4.4.58 R. However, for the purposes of that formula, the total annual sales referred to in BIPRU 4.4.59 R are the weighted average by individual exposures of the pool. The input parameters PD and LGD and the exposure value must be determined under the applicable
For purchased corporate exposure receivables in respect of which a firm cannot demonstrate that its PD estimates meet the minimum IRB standards, the PDs for these exposures must be determined according to the following methods:(1) for senior claims on purchased corporate exposure receivables PD must be the firm's estimate of EL divided by LGD for these receivables;(2) for subordinated claims on purchased corporate exposure receivables PD must be the firm's estimate of EL; and1(3)
In the case of corporate exposures, for dilution risk of purchased receivables PD must be set equal to EL estimate for dilution risk. If a firm is under its IRB permission using the advanced IRB approach for LGD estimates for corporate exposures and it can decompose its EL estimates for dilution risk of purchased corporate exposure receivables into PDs and LGDs in a reliable manner, the PD estimate may be used. A firm may recognise unfunded credit protection in the PD in accordance
In the case of retail exposures, for dilution risk of purchased receivables PD must be set equal to EL estimates for dilution risk. If a firm can decompose its EL estimates for dilution risk of purchased receivables into PDs and LGDs in a reliable manner, the PD estimate may be used.[Note: BCD Annex VII Part 2 point 19]
The following LGD values apply for purchased corporate exposure receivables:(1) for senior purchased corporate exposure receivables exposures where a firm cannot demonstrate that its PD estimates meet the minimum IRB standards, the value is 45%;(2) for subordinated purchased corporate exposure receivables exposures where a firm cannot demonstrate that its PD estimates meet the minimum IRB standards, the value is 100%; and(3) for dilution risk of purchased corporate exposure receivables,
Notwithstanding BIPRU 4.4.34 R and BIPRU 4.8.25 R, for dilution risk and default risk if a firm is under its IRB permission using the advanced IRB approach for LGD estimates for corporate exposures and it can decompose its EL estimates for purchased corporate exposure receivables into PDs and LGDs in a reliable manner, the LGD estimate for purchased corporate exposure receivables may be used.[Note: BCD Annex VII Part 2 point 9]
(1) The exposure value for the items in (2) must be calculated as the committed but undrawn amount multiplied by a conversion factor.(2) For undrawn purchase commitments for revolving purchased receivables that are unconditionally cancellable or that effectively provide for automatic cancellation at any time by the firm without prior notice, a conversion factor of 0% applies. To apply a conversion factor of 0%, a firm must actively monitor the financial condition of the obligor,
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
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)]
To the extent that a firm'sIRB permission permits this, implementation may be carried out sequentially across the different IRB exposure classes within the same business unit, across different business units in the same group or for the use of own estimates of LGDs or conversion factors for the calculation of risk weights for the sovereign, institution and corporate IRB exposure class.3[Note:BCD Article 85(1) (part)]
(1) Implementation of the IRB approach as referred to in BIPRU 4.2.18 R must be carried out within a reasonable period of time as set out in the IRB permission.(2) The implementation must be carried out subject to strict conditions determined by the FSA and set out in the IRB permission.(3) A firm must not use the flexibility under BIPRU 4.2.18 R selectively with the purpose of achieving reduced minimum capital requirements in respect of those IRB exposure classes or business
Subject to BIPRU 4.2.17 R - BIPRU 4.2.20 R, BIPRU 4.2.22 R and BIPRU 4.2.26 R, a firm that has an IRB permission must not use the standardised approach for the calculation of risk weighted exposure amounts for the exposures to which the IRB approach applies under the IRB permission.[Note:BCD Article 85(4)]1
Subject to BIPRU 4.2.17 R - BIPRU 4.2.22 R and BIPRU 4.2.26 R, a firm whose IRB permission provides for the use of the advanced IRB approach for the calculation of LGDs and conversion factors for the sovereign, institution and corporate IRB exposure class must not use the LGD values and conversion factors applicable to the foundation IRB approach for the exposures to which the advanced IRB approach applies under the IRB permission.[Note:BCD Article 85(5)]
(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
For the purposes of BIPRU 4.2.26 R (4), the equity exposureIRB exposure class of a firm must be considered material if its aggregate value, excluding equity exposures incurred under legislative programmes as referred to in BIPRU 4.2.26 R (8) but including exposures in a CIU treated as equity exposures in accordance with BIPRU 4.9.11 R to BIPRU 4.9.15 R,4 exceeds, on average over the preceding year, 10% of the firm'scapital resources. If the number of those equity exposures is
(1) Where the credit risk mitigation used relies on the right of a firm to liquidate or retain assets, eligibility depends upon whether risk weighted exposure amounts, and, as relevant, expected loss amounts, are calculated under the standardised approach or the IRB approach.(2) Eligibility further depends upon whether the financial collateral simple method is used or the financial collateral comprehensive method.(3) In relation to repurchase transactions and securities or commodities
A firm may choose to use the supervisory volatility adjustments approach or the own estimates of volatility adjustments approach independently of the choice it has made between the standardised approach and the IRB approach for the calculation of risk weighted exposure amounts. However, if a firm seeks to use the own estimates of volatility adjustments approach, it must do so for the full range of instrument types, excluding immaterial portfolios where it may use the supervisory
The IRB approach is an alternative to the standardised approach for calculating a firm's credit risk capital requirements. It may be applied to all a firm'sexposures or to some of them, subject to various limitations on partial use as set out in BIPRU 4.2. Under the IRB approach capital requirements are based on a firm's own estimates of certain parameters together with other parameters set out in the Banking Consolidation Directive.
If a provision of the Handbook relating to the IRB approach says that a firm may do something if its IRB permission allows it, a firm may do that thing unless its IRB permission expressly says that it may not do so except that:(1) BIPRU 4.2.18 R - BIPRU 4.2.19 R (Sequential implementation of IRB approach) and BIPRU 4.2.26 R (1)-BIPRU 4.2.26R (5) (Combined use of standardised approach with IRB approach) only apply if expressly permitted by a firm'sIRB permission;(2) a firm may
For an originator, a sponsor, or for other firms which can calculate KIRB, the risk weighted exposure amounts calculated in respect of its positions in a securitisation may be limited to that which would produce an amount in respect of its credit risk capital requirement equal to the sum of 8% of the risk weighted exposure amount which would be produced if the securitised assets had not been securitised and were on the balance sheet of the firm plus the expected loss amounts of
(1) If:(a) a firm'sIRB permission allows it to use this treatment; and(b) the conditions in (2)(16) are satisfied,a firm may attribute to an unrated position in an asset backed commercial paper programme a derived rating as laid down in (3).(2) Positions in the commercial paper issued from the programme must be rated positions.(3) Under the ABCP internal assessment approach, the unrated position must be assigned by the firm to one of the rating grades described in (5). The position
(1) Subject to any permission of the type described in BIPRU 9.12.28 G, the risk weight to be applied to the exposure amount must be:12.5 (S[L+T] - S[L]) / T(2) The remaining provisions of this paragraph define the terms used in the formulae in (1) and (3).(3) 2(4) (5) (6) (7) (8) (9) (10) (11) (12) (13) (14) (15) In these expressions, Beta [x; a, b]refers to the cumulative beta distribution with parameters a and b evaluated at x.(16) T (the thickness of the tranche in which the
(1) When it is not practical for the firm to calculate the risk weighted exposure amounts for the securitised exposures as if they had not been securitised and the position does not qualify for the ABCP internal assessment approach, a firm may apply to the FSA for a variation of its IRB permission under which, on an exceptional basis, it may temporarily apply the method in (2) for the calculation of risk weighted exposure amounts for an unratedsecuritisation position in the form
Within the corporate exposureIRB exposure class, a firm must separately identify as specialised lending exposures, exposures which possess the following characteristics:(1) the exposure is to an entity which was created specifically to finance and/or operate physical assets;(2) the contractual arrangements give the lender a substantial degree of control over the assets and the income that they generate; and(3) the primary source of repayment of the obligation is the income generated
A firm may generally assign preferential risk weights of 50% to exposures in category 1, and a 70% risk weight to exposures in category 2 if:(1) its IRB permission allows this; and(2) the firm's underwriting characteristics and other risk characteristics are substantially strong for the relevant category.[Note:BCD Annex VII Part 1 point 6 (part)]
Where a firm'sIRB permission authorises it generally to assign preferential risk weights as outlined in BIPRU 4.5.10 R of 50% to exposures in category 1, and 70% to exposures in category 2, the EL value for exposures in category 1 must be 0%, and for exposures in category 2 must be 0.4%.[Note:BCD Annex VII Part 1 point 31 (part)]
(1) For firms using the IRB approach set out in BIPRU 4, this paragraph applies in place of BIPRU 9.13.4 R.(2) For the purposes of this section, originators interest means the sum of:(a) the exposure value of that notional part of a pool of drawn amounts sold into a securitisation, the proportion of which in relation to the amount of the total pool sold into the structure determines the proportion of the cash-flows generated by principal and interest collections and other associated
For firms using the IRB approach set out in BIPRU 4, this paragraph applies in place of BIPRU 9.13.5 R. The exposure of the originator associated with its rights in respect of that part of the originators interest described in BIPRU 9.13.6 R (2)(a) must not be treated as a securitisation position but as a pro rata exposure to the securitised drawn amounts as if they had not been securitised in an amount equal to that described in BIPRU 9.13.6 R (2)(a). The originator must also
A firm may determine exposures arising from long settlement transactions using any of the CCR mark to market method, the CCR standardised method and the CCR internal model method, regardless of the methods chosen for treating financial derivatives instruments and repurchase transactions, securities or commodities lending or borrowing transactions, and margin lending transactions. In calculating capital requirements for long settlement transactions, a firm that uses the IRB approach
When a firm purchases credit derivative protection against a non-trading book ,exposure or against a CCRexposure, it must compute its capital requirement for the hedged asset in accordance with:(1) BIPRU 5.7.16 R to BIPRU 5.7.25 R and BIPRU 4.10.49 R (4) to (6) (Unfunded credit protection: Valuation and calculation of risk-weighted exposure amounts and expected loss amounts); or1(2) 1where a firm calculates risk weighted exposure amounts in accordance with the IRB approach:1(a)
The following must be calculated in accordance with BIPRU 9 (Securitisation):(1) risk-weighted exposure amounts for securitisedexposures and for exposures belonging to the IRB exposure class referred to in BIPRU 4.3.2 R (6) (securitisation positions); and(2) the expected loss amounts for securitisedexposures.[Note: BCD Article 87(10) and Article 88(3)]
Where a firm obtains credit protection for a number of exposures under terms that the first default among the exposures will trigger payment and that this credit event will terminate the contract, the firm may modify the calculation of the risk weighted exposure amount and, as relevant, the expected loss amount of the exposure which would in the absence of the credit protection produce the lowest risk weighted exposure amount under the standardised approach or the IRB approach
A firm may use the master netting agreement internal models approach independently of the choice it has made between the standardised approach and the IRB approach for the calculation of risk weighted exposure amounts. However, if a firm uses the master netting agreement internal models approach, it must do so for all counterparties and securities, excluding immaterial portfolios where it may use the supervisory volatility adjustments approach or the own estimates of volatility
A firm must disclose the following information regarding compliance with BIPRU 3, BIPRU 4, BIPRU 6, BIPRU 7, BIPRU 10 and the overall Pillar 2 rule:(1) a summary of the firm's approach to assessing the adequacy of its internal capital to support current and future activities;(2) for a firm calculating risk weighted exposure amounts in accordance with the standardised approach to credit risk, 8% of the risk weighted exposure amounts for each of the standardised credit risk exposure
