Subregulation (11) Method 1 : Calculation of credit risk exposure in terms of the foundation IRB approach

Subregulation (11)(d) Risk-weighted exposure

 

(d) Risk-weighted exposure

 

(i) Unless specifically otherwise provided in this paragraph (d), in order to calculate its risk-weighted credit exposure, a bank that adopted the foundation IRB approach for the measurement of the bank's exposure to credit risk in respect of positions held in the bank's banking book—
(A) shall in the case of exposures other than retail exposures and purchased retail receivables calculate its own estimate of probability of default ("PD") in respect of each relevant borrower grade or credit exposure;
(B) shall in the case of retail exposures and purchased retail receivables calculate its own estimate of PD in respect of each relevant pool of retail exposures;
(C) shall in the case of exposures other than retail exposures and purchased retail receivables apply standardised estimates in respect of loss-given-default ( "LGD"), exposure-at-default ("EAD") and maturity ("M"), which standardised estimates—
(i) are specified below in respect of each relevant asset class; or
(ii) shall be determined by the Registrar;
(D) shall in the case of retail exposures and purchased retail receivables calculate its own estimates of LGD and EAD;
(E) shall apply the risk-weight functions and risk components in respect of the various exposure categories envisaged in paragraph (c) above in ccordance with the relevant requirements specified in this paragraph (d);
(F) shall in the case of securitisation exposures apply the risk-weight functions and risk components in respect of the various types of securitisation exposure in accordance with the relevant requirements specified in paragraphs (e) to (p) below.

 

(ii) Corporate, sovereign and bank exposures

 

A bank that adopted the foundation IRB approach for the measurement of the bank's exposure to credit risk shall calculate its risk-weighted assets in respect of corporate, sovereign or bank exposures through the application of the formula and risk components specified below:

 

(A) In the case of an exposure other than an exposure to a small or medium sized entity ("SME"), which exposure is not in default, as follows:

 

RWA = K x 12,5 x EAD

 

where:

 

RWA is the risk weighted asset amount.

 

K is the capital requirement, which capital requirement shall be calculated through the application of the formula specified below

 

K = [LGD x N [(1 - R)^-0.5 x G (PD) + (R/(1 - R))^0.5 x G(0.999)] - PD x LGD] x (1 - 1.5 x b)^ -1 x (1 + (M - 2.5) x b)

 

Provided that when the calculation of K results in a negative capital requirement in respect of a particular exposure, the bank shall apply a capital requirement equal to zero in respect of the relevant exposure.

 

PD is the probability of default, and constitutes a ratio

 

In the case of exposures to—

(i) corporate institutions or banks, the PD ratio shall be equal to the higher of the one-year PD associated with the relevant internal grade to which the exposure is assigned, or 0.03 per cent;
(ii) sovereigns, the PD ratio shall be the one-year PD ratio associated with the relevant internal grade to which the exposure is assigned;
(iii) intragroup banks or other formally regulated intragroup financial entities with capital requirements similar or equivalent to these Regulations, which banks or entities are included in the consolidated amounts calculated in accordance with the relevant requirements specified in these Regulations in respect of consolidated supervision, the PD ratio shall be deemed to be equal to zero.

 

LGD is the loss-given-default ratio

 

In the case of—

(i) senior claims not secured by eligible collateral, a bank shall apply a ratio of 45 per cent;
(ii) subordinated claims, that is, a facility that is expressly subordinated to another facility, a bank shall apply a ratio of 75 per cent.

 

M is the effective maturity of the relevant exposure, which maturity shall be regarded as being equal to 2.5 years unless the exposure relates to a repurchase or resale transaction in which case an effective maturity equal to six months shall apply, provided that—
(i) the Registrar may require; or
(ii) on prior written application by the reporting bank and subject to such conditions as may be specified in writing, the Registrar may allow,

a bank to calculate the effective maturity of a particular exposure in accordance with the relevant requirements specified in subregulation (13)(d)(ii)(B) below

 

R is the relevant correlation, which correlation shall be calculated through the application of the formula specified below

 

R = 0.12 x (1 - EXP (-50 x PD)) / (1 - EXP (-50)) + 0.24 x [1 - (1 - EXP(-50 x PD))/(1 - EXP(-50))]

 

Provided that the bank shall apply a multiplication factor of 1.25 to the aforesaid correlation parameter "R", such that correlation RFI = 1.25 x R1 in respect of all relevant exposures to financial institutions, as follows:

(i) any regulated financial institution with total assets greater than or equal to R700 billion,
(aa) which asset amount shall be based on the most recent consolidated audited financial statements of the relevant parent company and its relevant subsidiaries;
(bb) which regulated financial institutions shall for purposes of these Regulations include any parent institution and its subsidiaries, where any relevant substantial legal entity in the consolidated group is supervised by a regulator that imposes prudential requirements consistent with such international norms as may be specified in writing by the Registrar, which institutions shall include, but are not limited to, prudentially regulated insurance companies, broker/dealers and banks;
(ii) any unregulated financial institution, regardless of size, which unregulated financial institutions shall for purposes of these Regulations include legal entities of which the main business includes—
(aa) the management of financial assets;
(bb) lending;
(cc) factoring;
(dd) leasing;
(ee) provision of credit enhancements;
(ff) securitisation or resecuritisation;
(gg) investments;
(hh) financial custody;
(ii) central counterparty services;
(jj) proprietary trading; or
(kk) such other financial services activities as may be specified or directed in writing by the Registrar

 

b is the relevant maturity adjustment, which maturity adjustment shall be calculated through the application of the formula specified below

 

b = (0.11852 - 0.05478 x In (PD))^2

 

In denotes the natural logarithm

 

EXP is the inverse of the natural logarithm, In

 

N(x) denotes the cumulative distribution function for a standard normal random variable, that is, the probability that a normal random variable with a mean equal to zero and variance of one is less than or equal to x.

 

G(z) denotes the inverse cumulative distribution function for a standard normal random variable, that is, the value of x such that N(x) = z.

 

EAD is the exposure at default, which exposure shall be measured gross of any specific credit impairment raised or partial write-offs made by the reporting bank.

 

A bank shall measure its exposure at default in accordance with the relevant requirements specified below:

(i) In the case of any drawn amounts, the exposure at default shall be equal to the sum of the drawn amounts after the effect of set-off in accordance with the relevant requirements specified in regulation 13 has been recognised, provided that the said exposure shall not be less than the sum of—
(aa) the amount by which the bank's capital requirement would be reduced when the exposure amounts are written off in full; and
(bb) any specific credit impairment raised or partial write-off made by the reporting bank in respect of the relevant exposure amounts.
(ii) In the case of off-balance-sheet items other than unsettled derivative contracts, the exposure at default shall be equal to the sum of committed but undrawn amounts multiplied by the relevant credit conversion factors specified in subregulation (6)(g), provided that—
(aa) in the case of any irrevocable undrawn commitment, note-issuance facility or revolving underwriting facility, instead of the credit conversion factors specified in subregulation (6)(g), the bank shall apply a credit-conversion factor of 75 per cent irrespective of the maturity of such commitments, note-issuance facilities or revolving underwriting facilities, unless the said exposures or a portion of the said exposures constitutes an uncommitted or revocable facility in which case the bank shall apply a credit–conversion factor equal to zero per cent in respect of the said uncommitted or revocable exposure, provided that in the case of—
(i) a constraining condition in respect of an unused committed facility, such as a limit on the available amount, which limit may relate to the financial position of the relevant obligor at a point in time, the bank shall apply the relevant credit-conversion factor to the lower amount of the unused committed facility and the said constraining limit;
(ii) a facility with a constraining condition as envisaged in item (i) above, the reporting bank shall have in place sufficiently robust line monitoring and management procedures that demonstrate to the satisfaction of the Registrar the ability of the bank to enforce the said constraining limit;
(iii) any uncommitted or revocable facility the reporting bank shall demonstrate to the satisfaction of the Registrar that the bank actively monitors the financial condition of the relevant obligor and that the internal control systems of the bank are adequate to cancel a facility upon receiving evidence of a deterioration in the credit quality of the relevant obligor;
(bb) when a commitment is obtained in respect of another off-balance-sheet exposure, the bank shall apply to the relevant exposure the lower of the relevant credit-conversion factors.
(cc) In the case where the bank has securitised the drawn balances of revolving facilities, the bank shall continue to hold required capital against the undrawn balances associated with the securitised exposures.

[Regulation 23(11)(d)(ii)(A)(cc) inserted by section 2(z) of Notice No. 2561, GG46996, dated 30 September 2022 - effective 1 October 2022]

RWA = K x12,5 x EAD

 

(ii) a bank shall assign to the relevant exposure a PD ratio equal to 100 per cent.

 

(C) In the case of an exposure to an SME borrower, which SME borrower would otherwise be categorised as a corporate exposure, the bank shall make an adjustment to the formula specified in item (A) above, which adjustment shall be calculated through the application of the formula specified below, provided that the reported sales for the consolidated group of which the SME borrower is a member shall be less than R400 million, provided that, subject to such conditions as may be specified in writing, the Registrar may specify in writing a different threshold amount and/or specify in writing to substitute sales for assets as the base.

(i) the bank shall comply with the relevant minimum requirements relating to retail exposures specified in paragraphs (b)(v)(D), (b)(vi)(B), (b)(viii)(D), (b)(viii)(E) and (c) (iv) above;
(ii) the bank may use external and internal reference data to estimate the PD ratio and LGD ratio relating to the relevant exposure;
(iii) when the bank complies with the relevant minimum requirements in respect of retail exposure as envisaged in sub-item (i) above, the bank may apply the "top-down" approach envisaged in paragraph (b)(vi)(F) above in order to calculate the said estimates of PD and LGD, provided that the bank shall in addition to the said requirements in respect of retail exposure comply with the relevant requirements relating to the "top-down" approach, specified in paragraph (b)(vi)(F) above.

 

(C) Purchased corporate receivables

(aa) when the bank is unable to decompose the expected loss ratio into its PD and LGD components, the bank—
(i) shall determine the risk weight in respect of the purchased corporate receivable from the corporate risk-weight function using a LGD ratio of 45 per cent provided that the exposures exclusively consist of senior claims in respect of corporate borrowers;
(ii) shall calculate the PD ratio by dividing the expected loss ratio by the LGD ratio of 45 per cent;
(iii) shall calculate the EAD amount as the outstanding amount minus the capital requirement relating to the risk of dilution, before the bank takes into consideration the effect of any risk mitigation instrument, provided that in the case of a revolving facility the EAD amount shall be equal to the purchased receivable amount plus 75 per cent of any undrawn purchased commitments minus the capital requirement relating to the risk of dilution;
(iv) shall in all cases other than the exposures already specified in this sub-item (aa), use a PD ratio equal to the expected loss ratio, a LGD ratio equal to 100 per cent and an EAD amount equal to the outstanding amount minus the capital requirement relating to the risk of dilution, before the bank takes into consideration the effect of any risk mitigation instrument;
(bb) when the bank is able to estimate the PD ratio in a reliable manner, the bank shall determine the risk weight in respect of the relevant exposure from the corporate risk weight function, based on the relevant requirements relating to LGD and M;
(ii) Subject to the prior written approval of and such conditions as may be specified in writing by the Registrar, a bank may apply the "top-down" approach envisaged in paragraph (b)(vi)(F) above in order to calculate the risk weight relating to default risk in respect of a pool of purchased corporate receivables, provided that—
(aa) the bank's programme in respect of purchased corporate receivables shall comply with the relevant requirements specified in paragraph (b)(vi)(F) above;
(bb) the receivables—
(i) shall be purchased from unrelated, third party sellers, that is, the receivables shall not be originated, either directly or indirectly, by the reporting bank;
(ii) shall be generated on an arm's-length basis between the seller and the relevant obligor;
(cc) the bank—
(i) shall have a claim in respect of all proceeds from the pool of receivables or a relevant pro rata interest in the proceeds, which claim shall exclude any first-loss or second-loss positions, that is, the cash flows arising from the purchased corporate receivables shall be the reporting bank's primary protection against default risk;
(ii) shall estimate the pool's one-year expected loss ratio for default risk, expressed as a percentage of the exposure amount, that is, the total EAD amount due to the bank by all obligors in the pool of purchased receivables;
(iii) shall estimate the expected loss ratio in respect of the purchased receivables on a stand-alone basis, that is, without regard to any assumption of recourse or guarantees from the seller or other parties;
(iv) shall, based on the pool's estimated one-year expected loss ratio for default risk, calculate the risk weight for default risk in accordance with the risk-weight function for corporate exposures specified in subparagraph (ii) above;
(v) shall utilise relevant external and internal data to estimate the required PD ratios and LGD ratios;
(vi) shall follow the directives specified in sub-item (i)(aa) above when the bank is unable to decompose the expected loss ratio into its PD and LGD components;
(dd) the Registrar shall grant approval to apply the "topdown" approach only in exceptional cases when the calculation of the bank's risk-weighted exposure in respect of purchased corporate receivables in accordance with the requirements specified in subparagraph (ii) relating to corporate exposure is likely to place an undue burden on the reporting bank;

 

(D) Purchase price discounts in respect of purchased receivables

 

A bank—

(i) shall risk weight any purchase price discount relating to purchased receivables which purchase price discount provides first-loss protection for defaulted loss, dilution losses or both in accordance with the securitisation framework, where to the extent that a portion of such a purchase price discount may be refunded to the seller based on the performance of the receivables –
(aa) the purchaser may recognise this refundable amount as first-loss protection;
(bb) the seller providing such a refundable purchase price discount, treat the refundable amount as a first-loss position.

Regulation 23(11)(d)(vi)(D)(i) substituted by section 2(bb) of Notice No. 2561, GG46996, dated 30 September 2022 - effective 1 October 2022]

(ii) shall ignore any purchase price discounts that were granted in respect of purchased corporate or retail receivables, other than purchase price discounts envisaged in sub-item (i), when the bank calculates its risk-weighted exposure or credit impairments relating to expected loss provided that the said discounts shall constitute non refundable amounts, that is, the said discounts shall not be paid or repaid to the relevant seller of the receivable amounts.
(iii) shall treat collateral or partial guarantees obtained on receivables that provide first-loss protection, that is the mitigants cover default losses, dilution losses or both, in accordance with the securitisation framework;

Provided that—

(aa) When the same mitigant covers both default and dilution risk, banks using the SEC-IRBA should calculate an exposure-weighted LGD as defined in subregulation (23)(11)(k).
