Dear Sir/Madam,
Revised Banking Returns – Capital Adequacy Ratio (Form MA(BS)3) (“CAR Return”), Leverage Ratio (Form MA(BS)27) (“LR Return”), Liquidity Position (Form MA(BS)1E) (“Liquidity Position Return”) and Stable Funding Position (Form MA(BS)26) (“Stable Funding Position Return”) I am writing to inform you that, following previous industry consultations, we have finalised the revisions to the CAR Return, LR Return and their respective Completion Instructions (“CIs”), as enclosed. Changes since the last version in use are highlighted for ease of reference. The revisions are mainly for implementing the Banking (Capital) (Amendment) Rules 2023 (“BCAR”) that are intended to come into effect on 1 January 2025. In addition, a few minor consequential amendments arising from the implementation of the BCAR have been made to the Stable Funding Position Return and its CIs, and the CIs for the Liquidity Position Return, as highlighted in the relevant enclosures. The STET software for the CAR Return, LR Return and Stable Funding Position Return will be available for downloading from the HKMA’s supervisory communication website (http://www.stet.iclnet.hk) in early January 2025. Reporting institutions should submit the CAR Return, LR Return, and Stable Funding Position Return based on the revised CIs to the HKMA, via the STET system, starting from the reporting position as of 31 March 2025, and the Liquidity Position Return starting from the reporting position as of 31 January 2025.

Completion Instructions
Return of Capital Adequacy Ratio
Forms MA(BS)3(I) to 3(VI)
Introduction

1. This return collects information on the capital adequacy position of authorized
   institutions incorporated in Hong Kong.
2. The return comprises 5 Parts 1
   , with Part III further divided into 5 sections for reporting institutions to report the risk-weighted amounts of their credit exposures under different approaches.

   I Summary certificate on capital adequacy ratios MA(BS)3(I) II Capital base MA(BS)3(II) III a Risk-weighted amount for credit risk – basic approach MA(BS)3(IIIa) b Risk-weighted amount for credit risk – standardized (credit risk) approach MA(BS)3(IIIb) c Risk-weighted amount for credit risk – internal ratings-based approach MA(BS)3(IIIc) d Risk-weighted amount for credit risk – securitization exposures MA(BS)3(IIId) e Risk-weighted amount for credit risk – central counterparties MA(BS)3(IIIe) V Risk-weighted amount for operational risk MA(BS)3(V) VI Risk-weighted amount for sovereign concentration risk MA(BS)3(VI) General Instructions Layout and application
3. Instructions provided under this section apply to all forms contained in this Return.
   Specific instructions relating to individual forms are separately provided. Reporting institutions should complete the forms that are relevant to them in accordance with these instructions, having regard to the Banking (Capital) Rules (BCR), as well as other relevant supervisory policy/guidance related to the capital adequacy framework issued by the HKMA.
4. In completing Part VI of this Return, reporting institutions should additionally have
   regard to the Banking (Exposure Limits) Rules as well as other relevant supervisory policy guidance related to the large exposure framework issued by the HKMA.

1 Part IV is intentionally omitted.

MA(BS)3(Introduction)/P.2 (03/2025)
5. Parts I, II and V are applicable to all reporting institutions. For Parts IIIa to IIIc on
Credit Risk, reporting institutions are required to submit form(s) for the approach(es) being used by them to risk-weight their non-securitization exposures. Parts IIId to IIIe and VI are applicable only if the institutions have exposures that are the subject of these Parts. Combined / consolidated return
6. Where applicable, the forms should be completed both on a solo (or solo-consolidated)
basis (i.e. the Combined Return) and on a consolidated basis (i.e. the Consolidated Return). Reporting institutions should make reference to the respective provisions of the BCR when reporting their solo, solo-consolidated or consolidated position (i.e. sections 29, 30 and 31 of the BCR respectively).
7. A reporting institution should include positions in the return as follows:
Solo basis All positions of the institution and its local and overseas branches / offices. Solo-consolidated basis All positions of the institution, its local and overseas branches / offices and its solo-consolidated subsidiaries as defined in section 4 of the BCR. Consolidated basis All positions of the institution’s consolidation group (including local and overseas branches) as defined in
section 4 of BCR.
Reporting institutions should obtain the necessary approvals from the Monetary Authority (MA) and follow the requirements that are relevant to their choice of calculation approaches as set out in Part 2 of the BCR. Instructions applicable to consolidated basis
8. If every member of a reporting institution’s consolidation group uses the same
approach in calculating the risk-weighted amount for a particular risk (i.e. credit, market, CVA, operational or sovereign concentration risk), the consolidation group should be treated as one single entity. The positions of individual members within the institution’s consolidation group with respect to each of the risk types should be aggregated. The consolidated risk-weighted amounts should be calculated according to the approaches as selected for credit risk, market risk and CVA risk and the approach as prescribed for operational risk. The consolidated risk-weighted amount for sovereign concentration risk should be calculated according to Part 10 of the BCR.
9. With the prior consent of the MA, members of a reporting institution’s consolidation
group may use different approaches in calculating the risk-weighted amount for a particular risk (i.e. credit, market or CVA risk). Where different approaches are used, the consolidated risk-weighted amount should be calculated by aggregating the risk￾weighted amounts for each of the members calculated separately (1) according to the approaches used by the member concerned for credit risk, market risk and CVA risk and (2) according to Part 10 of the BCR in respect of sovereign concentration risk.

MA(BS)3(Introduction)/P.3 (03/2025)
10. Any inter-company balances, transactions, income and expenses, as the case may be,
among members of the consolidation group shall be eliminated in the calculation.
11. With the prior consent of the MA, a reporting institution may be allowed to calculate
the capital charge for exposures of its one or more than one subsidiary incorporated in overseas countries in accordance with the capital adequacy standards adopted by the host supervisors of these subsidiaries. Submission dates

Completion Instructions
Return of Capital Adequacy Ratio
Part I – Summary Certificate on Capital Adequacy Ratios
Form MA(BS)3(I)
Introduction

1. Form MA(BS)3(I) is divided into three divisions:
   (a) Divisions A and C – to be completed by all reporting institutions (reporting AIs); (b) Division B – to be completed by reporting AIs subject to the output floor requirement (except for the filtering question that all reporting AIs are required to answer).
2. Division A is for a reporting AI to provide summary information on its quarter-end
   Common Equity Tier 1 capital ratio, Tier 1 capital ratio and Total capital ratio and the relevant aggregate figures (mainly extracted from other parts of the Return) for computing the ratios. Division B collects information relating to the output floor by a reporting AI using a model-based approach to calculate its credit risk or market risk or both. Division C is for a reporting AI to report information relating to capital buffer requirements applicable to it.
3. This return and its completion instructions should be read in conjunction with the
   Banking (Capital) Rules (BCR) and the relevant supervisory policy/guidance on the capital adequacy framework. Specific Instructions Division A: Calculation of Capital Adequacy Ratios
4. The figures reported for items 1.1 to 1.3, 2.1 to 2.4 1
   , 2.6(i) and (ii), 2.8, 2.8a, 2.9 and
   2.9a should be extracted from other parts of the Return. See Annex I-A for a mapping
   table on items in this Form and the corresponding items in other Forms.
5. For reporting AIs that are subject to the output floor requirement, the figure reported
   for item 2.10 should be equal to item 4 of Division B.
6. Item 2.12(i) must be completed by the reporting AI if regulatory reserve for general
   banking risks and collective provisions have been made for or apportioned to— (a) its non-securitization exposures that are risk-weighted by using the basic approach (BSC approach) or the standardized (credit risk) approach (STC approach); or

Item 2.5 is intentionally omitted.

MA(BS)3(I)/P.2 (03/2025)
(b) its securitization exposures that are risk-weighted by using the securitization external ratings-based approach (SEC-ERBA), securitization standardized approach (SEC-SA) and securitization fall-back approach (SEC-FBA). The AI must report in this item the amount of the above regulatory reserve for general banking risks and collective provisions that exceeds 1.25% of the credit RWA reported under items 2.1, 2.2 and 2.6(ii). To avoid doubts, risk-weighted amount for CCP, if any, is excluded for the calculation of this 1.25% cap.
7. Item 2.12(ii) refers to the portion of cumulative fair value gains arising from the
revaluation of the AI’s holdings of land and buildings (except land and buildings mortgaged to the reporting AI to secure a debt) which is not included in Tier 2 Capital. For this purpose, whether such amount should be net or gross of deferred tax liabilities will be based on the prevailing accounting standards applicable within a given jurisdiction. Division B: Calculation of Output Floor
8. All reporting AIs should answer the filtering question at the top of Division B by
inputting either “Yes” or “No” to indicate whether the institution is subject to the output floor requirement as at the reporting date.
9. Reporting AIs using any of the model-based approaches stipulated in section 355 of the
BCR are subject to the calculation of the output floor and should answer “Yes” for the filtering question and complete the rest of Division B. Other reporting AIs should go directly to Division C. (A) Calculation of floor risk-weighted amount and actual risk-weighted amount for the application of output floor
10. A reporting AI which is subject to the output floor should calculate the difference
between:
(a) the floor risk-weighted amount for credit risk, market risk, CVA risk and operational risk as calculated in accordance with section 356 of the BCR (details to be reported under items 1(i) to (iv) respectively); and (b) the actual risk-weighted amount for credit risk, market risk, CVA risk and operational risk as calculated in accordance with section 357 of the BCR (details to be reported under items 2(i) to (iv) respectively). A reporting AI is required to report the difference in item 3 and, if any, the additional risk-weighted amount due to the application of output floor in item 4 (see section 358 of the BCR).

MA(BS)3(I)/P.3 (03/2025)
(B) Output Floor Level
11. A 5-year phase-in arrangement is adopted for the implementation of the output floor
level (see the table below). A reporting AI is required to report its applicable output floor level according to section 356(8) 2 of the BCR in item 1(vi). Calendar Year Output floor level 2025 50% 2026 55% 2027 60% 2028 65% 2029 70% 2030 onwards 72.5% (C) Treatment of concerned exposures
12. To determine the floor risk-weighted amount, section 356(4) of the BCR provides an
optional method to risk-weight concerned exposures under section 356(4) of the BCR (in general, unrated general corporate exposures other than those (i) extended to small business corporates, (ii) subject to section 61(3) or (4) of the BCR, and (iii) exempted from the use of the IRB approach) according to the loan classification categories (i.e. loan classification method) alternate to the use of risk-weight for 100% set out in
section 61(2)(a) of the BCR. Concerning this Form, the reporting AIs chosen for the
loan classification method are required to report the exposure amount (as defined in
section 51(1) of the BCR) and the risk-weighted amount of those concerned exposures
in memorandum items 5 and 6 respectively.
13. Once a reporting AI chooses the loan classification method, it must apply the method
consistently over time and must not change the method without the MA’s prior consent under section 356(5) of the BCR. Also, the reporting AIs which select to use the loan classification method are expected to be capable of mapping these exposures to the loan classification categories by referencing the loan classification criteria in the Guideline on Loan Classification System 3 , internal provisioning policies and practices, and the assessment with the institution’s rating system (where appropriate).

2 According to section 356(9), the MA may require a reporting AI to apply an output floor level specified in a notice under certain circumstances. 3 Section 5 of the Guideline clarifies that the criteria therein could be extended to credit exposures beyond “loans”, including “exposures arising from credit commitments and contingent liabilities”. Without limiting the reporting AI’s practice of mapping, as a general reference, the institution may consider an outline of an exemplified mapping –

MA(BS)3(I)/P.4 (03/2025)
Division C: Capital Buffer Requirements
14. A reporting AI is required to observe the following in reporting under this Division:
Item Reporting

1. Net CET1 capital
   ratio 4
   Report the ratio, expressed as a percentage, of (a) the amount of the AI’s CET1 capital less the amount of CET1 capital that the AI requires for maintaining (i) the minimum CET1 capital ratio, Tier 1 capital ratio and Total capital ratio applicable to it as set out in section 3B of the BCR and as varied by the MA under section 97F of the Banking Ordinance and (ii) the minimum external or internal LAC risk-weighted ratio (as the case requires) that the AI is required to maintain under the Financial Institutions (Resolution) (Loss-absorbing Capacity Requirements – Banking Sector) Rules, to (b) the sum of the AI’s risk-weighted amount for credit risk, risk-weighted amount for market risk, risk-weighted amount for CVA risk, risk-weighted amount for operational risk and risk-weighted amount for sovereign concentration risk, as determined in accordance with the BCR (i.e. the Total risk-weighted amount as reported under item 2.13 in Division A). Please refer to the illustrative examples in Annex I-B on how to calculate the net CET1 capital ratio.
2. Buffer level Report the buffer level that is applicable to an AI,
   expressed as a percentage and calculated according to
   section 3G of the BCR –
   (a) if the AI is a G-SIB or a D-SIB –
   Item 2.1 + 2.2 + 2.3 in this Division; or
   (b) in any other cases –
   Item 2.1 + 2.2 in this Division.
   2.1 Capital
   conservation buffer ratio (CB ratio)
   Report the CB ratio for calculating an AI’s buffer level under section 3G of the BCR as at the reporting date.
   2.2 Countercyclical
   capital buffer ratio
   (CCyB ratio)
   Report the CCyB ratio for calculating an AI’s buffer level under section 3G of the BCR as at the reporting date.

(a) if, apart from off-balance sheet exposures, the reporting AI also has a loan exposure to that particular unrated corporate obligor, it can apply the same loan classification grade of the loan exposure, where appropriate, to the off-balance sheet exposures, with adjustments to transactional characteristics as appropriate; and (b) if not, the reporting AI could categorise the off-balance sheet exposures based on the underlying principle of loan classification (for example, an institution may consider classifying an exposure to a Pass grade by mirroring the characteristics of a Pass “loan” that the obligor or the counterparty is “current in meeting commitments and the financial standing is not in doubt”). 4 Reporting reflects calculation requirement under section 3E(2) of the BCR.

MA(BS)3(I)/P.5 (03/2025)
Item Reporting
The CCyB ratio reported in this item should be consistent with the ratio reported in the cell labelled “CCyB ratio” in column (8) of the Quarterly Reporting on the Countercyclical Capital Buffer (Form MA(BS)25).
2.3 Higher loss
absorbency ratio
(HLA ratio)
Report the HLA ratio notified by the MA as applicable to the AI, if any, for calculating the AI’s buffer level under section 3G of the BCR as at the reporting date. Hong Kong Monetary Authority March 2025

Illustrative examples to calculate the net CET1 capital ratio Scenario 1 Suppose Bank A is classified as a resolution entity under the Financial Institutions (Resolution) (Loss-absorbing Capacity Requirements – Banking Sector) Rules (AI LAC Rules). Bank A’s risk-weighted amount is 100 units and it has 15 units of Total capital (comprising 14 units of CET1 capital and 1 unit of Tier 2 capital) and 8 units of non-capital LAC debt resources. Therefore, the CET1 capital ratio, Tier 1 capital ratio, Total capital ratio and external LAC risk￾weighted ratio of Bank A are 14%, 14%, 15% and 23% respectively. Taking into account Bank A’s minimum capital adequacy and loss-absorbency capacity (LAC) requirements (assuming 5.3%, 7.1%, 9.5% and 19% for CET1 capital ratio, Tier 1 capital ratio, Total capital ratio and external LAC risk-weighted ratio respectively in this scenario), the calculation of the net CET1 capital ratio includes the following steps:

(as varied under s.97F of the BO)
CET1 capital required to meet Bank A’s capital requirement Remarks CET1 capital 14.0% 5.3% 5.3 units Tier 1 capital 14.0% 7.1% = 5.3 + (7.1 - 5.3) = 5.3 + 1.8 = 7.1 units Since Bank A has no Additional Tier 1 capital, the bank must make use of an additional 1.8 unit of CET1 capital to meet its Tier 1 capital requirement Total capital 15.0% 9.5% = 7.1 + [(9.5 - 7.1) - 1] = 7.1+1.4 = 8.5 units Since Bank A has only 1 unit of Tier 2 capital and no Additional Tier 1 capital, the bank must make use of an additional 1.4 unit of CET1 capital to meet its total capital requirement

Therefore, the CET1 capital ratio, Tier 1 capital ratio, Total capital ratio and external LAC risk-weighted ratio of Bank B are 14%, 16%, 18% and 26% respectively. Taking into account Bank B’s minimum capital adequacy and LAC requirements (assuming 5.3%, 7.1%, 9.5% and 19% for CET1 capital ratio, Tier 1 capital ratio, Total capital ratio and external LAC risk-weighted ratio respectively in this scenario), the calculation of the net CET1 capital ratio includes the following steps:

Item Nature of item
Part II Capital Base
5. For the purpose of calculating the institution’s CAR, the
capital base of the institution shall be the sum of the institution’s Tier 1 capital (being the sum of the Common Equity Tier 1 (CET1) capital and Additional Tier 1 capital) and Tier 2 capital, calculated in Hong Kong dollars after taking into account items excluded under section 38(2) and regulatory deductions specified in Part 3 Division 4 of the BCR.

6. The institution shall include in its CET1 capital, Additional
   Tier 1 capital or Tier 2 capital the proceeds of eligible instruments only to the extent that the instruments have been paid-up and are immediately available to the issuer of the instrument; or in the case of Additional Tier 1 or Tier 2 capital instruments are not issued out of an operating entity or any holding company of the institution, an operating entity or the holding company of the institution, as the case may be.
7. As outlined in paragraphs 55 and 78, if the institution has
   insufficient capital in a particular tier from which to make the required deductions, the remainder of the deduction amount (i.e. after bringing the net capital for that tier to zero) should be deducted from the next higher tier of capital. There are specific line items on the return to accommodate these transfers in deductions up the tiers.

(d) Disclosed reserves 2
12. Report the institution’s disclosed reserves in item (d). The
amount of revaluation reserves in relation to financial assets at fair value through other comprehensive income that has been included in item (d) should be separately reported in item (d)(i). (e) Minority interests arising from CET1 capital instruments issued by the consolidated bank subsidiaries of the institution and held by third parties
13. Where the MA requires under section 3C of the BCR that the

Schedule 4D (Requirements to be Met for Minority Interests
and Capital Instruments Issued by Consolidated Bank Subsidiaries and Held by Third Parties to be Included in Authorized Institution’s Capital Base) of the BCR.
14. The maximum amount of minority interests in the bank
subsidiary that can be included in the CET1 capital of the institution on a consolidated basis is calculated as:
A – (B * C) where:
A gross amount of total qualifying CET1 capital instruments of the bank subsidiary issued to third parties B (If the bank subsidiary is incorporated in Hong Kong) surplus CET1 capital of the subsidiary = CET1 capital of the bank subsidiary (after taking into account items under

(Item ii. corresponds to the portion, calculated as the consolidated minimum CET1 capital requirement plus the buffer level applicable to the institution) Or (If the bank subsidiary is not incorporated in Hong Kong) surplus CET1 capital of the subsidiary = CET1 capital of the bank subsidiary (after taking into account items under
section 38(2) and deductions under sections 43 to 46 of
the BCR) less –
iii. the portion of the sum of risk-weighted amount for
credit risk, market risk, CVA risk, operational risk

MA(BS)3(II)/P.6 (03/2025) and sovereign concentration risk of the institution calculated on a consolidated basis, that relates to the bank subsidiary, multiplied by the percentage equal to the sum of – (I) the minimum CET1 capital ratio that the institution must comply with on a consolidated basis, under section 3B of the BCR and, if applicable, as varied by the MA under section 97F of the Banking Ordinance (specified minimum ratio); and (II) the buffer level applicable to the institution under section 3G of the BCR. (Item iii. corresponds to the portion, calculated as the consolidated minimum CET1 capital requirement plus the buffer level applicable to the institution) Note:
An institution may choose to use 4.5% (substitute percentage) instead of the specified minimum ratio referred to in items B.i.(I), B.ii.(I) and B.iii.(I) above. C percentage of CET1 capital instruments of the bank subsidiary held by third parties
15. The calculation as shown above must be undertaken for each
individual bank subsidiary separately. If the institution has chosen to use the substitute percentage, it must not, without the MA’s prior consent, use the specified minimum ratio subsequently. In addition, an institution must use only either the specified minimum ratio or the substitute percentage in respect of all of its bank subsidiaries that are members of its consolidation group.
16. Annex II-A is an illustrative example on how to calculate the
applicable amount of minority interests and capital instruments issued by consolidated bank subsidiaries and held by third parties to be included in an institution’s capital base.

17. This is the sum of items (a) to (e) in Column 2.
Regulatory deductions from CET1 Capital
18. The institution must exclude/deduct items (f)(i) to (f)(xxii)
from its CET1 capital, if applicable, in accordance with the provisions set out in Part 3 of the BCR. With respect to the regulatory deduction of an institution’s LAC investments in capital instruments issued by or non￾capital LAC liabilities of financial sector entities and capital investments in commercial entities, Annex II-B provides an illustration showing the relevant components of different types of LAC investments and loans, facilities or credit exposures that are required to be deducted from CET1 capital, Additional Tier 1 capital and Tier 2 capital under the BCR. (f)(i) Cumulative cash flow hedge reserves that relate to the hedging of financial instruments that are not fair-valued on the balance sheet
19. Report the amount of cumulative cash flow hedge reserves
that relates to the hedging of financial instruments that are not fair-valued on the balance sheet (including projected cash flows) in this item. Net fair value losses on revaluation of cash flow hedge should be added back to the institution’s CET1 capital and reported in item (f)(i) with a negative sign.

In this connection, the HKMA will generally follow the applicable accounting treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the institution holding a capital position upon completion of the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the institution, it may treat the uncompleted transaction as not constituting a potential future holding.

(f)(xvii) Reciprocal cross holdings in CET1 capital instruments
38. Report the amount of any direct, indirect and synthetic

In this connection, the HKMA will generally follow the applicable accounting

MA(BS)3(II)/P.14 (03/2025) treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the institution holding a capital position upon completion of the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the institution, it may treat the uncompleted transaction as not constituting a potential future holding.
43. The applicable amount to be deducted from the institution’s
CET1 capital under paragraph 41 above should be determined by the formula in the first column of the following table:
Applicable Amount Reference to Schedule
4F of the BCR
(For deduction of holdings by an institution that is a “section 2 institution” as defined in section 2 of Schedule 4F to the BCR 6 ) Excess(10% threshold)(net long) * CET1 percentage Sections 1, 2, 4 (For deduction of holdings by an institution that is a “section 3 institution” (within the meaning of section 3 of Schedule 4F to the BCR) or treated as such by virtue of section 2(2) of Schedule 4F) Excess(10% threshold)(net long) * CET1 percentage Sections 1, 3, 4

(i) exclude holdings of capital instruments issued by financial sector entities that are not included within regulatory capital in the relevant financial sectors in which those entities operate; (ii) reduce the amount to be deducted under item (f)(xx) by any amount of goodwill (related to any holdings of shares falling within such item) already deducted under section 43(1)(a) of the BCR; and (iii) include in the amount to be deducted under item (f)(xx) potential future holdings that the institution could be contractually obliged to purchase. In this connection, the HKMA will generally follow the applicable accounting treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the

MA(BS)3(II)/P.16 (03/2025) institution holding a capital position upon completion of the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the institution, it may treat the uncompleted transaction as not constituting a potential future holding.

53. For the purposes of paragraph 52(i) above, the institution
must:
(i) exclude holdings of capital instruments issued by financial sector entities that are not included within regulatory capital in the relevant financial sectors in which those entities operate; (ii) reduce the amount to be deducted under item (f)(xxi) by any amount of goodwill (related to any holdings of shares falling within such item) already deducted under section 43(1)(a) of the BCR; and (iii) include in the amount to be deducted under item (f)(xxi) potential future holdings that the institution could be contractually obliged to purchase. In this connection, the HKMA will generally follow the applicable accounting treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the institution holding a capital position upon completion of the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the institution, it may treat the uncompleted transaction as not constituting a potential future holding.
54. Report separately in item (f)(xxi)(1) the amount of any loans,
facilities or other credit exposures described in paragraph 52(ii) above that is included in the amount reported in item (f)(xxi). (f)(xxii) Regulatory deductions applied to CET1 capital due to insufficient

MA(BS)3(II)/P.18 (03/2025)
Additional Tier 1 capital to cover the required deductions

(Item iii. corresponds to the portion, calculated as the consolidated minimum Tier 1 capital requirement plus the buffer level applicable to the institution) Note:
An institution may choose to use 6% (substitute

MA(BS)3(II)/P.22 (03/2025) percentage) instead of the specified minimum ratio referred to in items B.i.(I), B.ii.(I) and B.iii.(I) above. C percentage of Tier 1 capital instruments of the bank subsidiary held by third parties
63. The amount of Tier 1 capital recognized in the Additional Tier
1 capital of an institution on a consolidated basis must exclude the portion that has been recognized in the consolidated CET1 capital under paragraph 13 above.
64. The calculation as shown above must be undertaken for each
individual bank subsidiary separately. If the institution has chosen to use the substitute percentage, it must not, without the MA’s prior consent, use the specified minimum ratio subsequently. In addition, the institution must use only either the specified minimum ratio or the substitute percentage in respect of all of its bank subsidiaries that are members of its consolidation group.
65. Annex II-A is an illustrative example on how to calculate the
applicable amount of minority interests and capital instruments issued by consolidated bank subsidiaries and held by third parties to be included in the institution’s capital base.

through a special purpose vehicle via a consolidated bank subsidiary of the institution and - (i) the special purpose vehicle is consolidated with the bank subsidiary; (ii) the capital instruments meet the AT1 Qualifying Criteria set out in Schedule 4B of the BCR; and (iii) the only asset of the special purpose vehicle is its investment in the capital of the bank subsidiary in a form that meets the AT1 Qualifying Criteria set out in
Schedule 4B of the BCR 8
, the institution may treat the capital instruments as if the bank subsidiary itself had issued the capital instrument directly to the third parties, and may include the capital instruments in determining the applicable amount of the capital instruments to be included in the Additional Tier 1 capital of the institution on a consolidated basis as stipulated in paragraph 61 above.

Regulatory deductions from Additional Tier 1 Capital
68. The institution must deduct the following items from its
Additional Tier 1 capital in accordance with the provisions set out in Part 3 of the BCR. With respect to the regulatory deduction of an institution’s LAC investments in capital instruments issued by and non￾capital LAC liabilities of financial sector entities and capital investments in commercial entities, Annex II-B provides an illustration showing the relevant components of different types of LAC investments and loans, facilities or credit exposures that are required to be deducted from CET1 capital, Additional Tier 1 capital and Tier 2 capital under the BCR. (i)(i) Investments in own Additional Tier 1 capital instruments
69. Report the amount of any direct, indirect and synthetic
holdings by the institution of its own Additional Tier 1 capital instruments, unless already derecognized under applicable accounting standards, calculated in accordance with the provisions of Schedule 4E of the BCR. For this purpose, the institution must:

In this connection, the HKMA will generally follow the applicable accounting treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the institution holding a capital position upon completion of

MA(BS)3(II)/P.24 (03/2025) the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the institution, it may treat the uncompleted transaction as not constituting a potential future holding.

of the institution’s direct, indirect and synthetic holdings of Additional Tier 1 capital instruments issued by financial sector entities, calculated in accordance with Schedule 4F of the BCR, if – (a) the entities are not the subject of consolidation under a section 3C requirement imposed on the

MA(BS)3(II)/P.25 (03/2025) institution; (b) the holdings are insignificant LAC investments; and (c) the holdings do not otherwise fall within items (i)(i) and (i)(ii) above. For this purpose, the institution must:
(i) exclude holdings of capital instruments issued by financial sector entities that are not included within regulatory capital in the relevant financial sectors in which those entities operate; (ii) reduce the amount to be deducted under item (i)(iii) by any amount of goodwill (related to any holdings of Additional Tier 1 capital instruments falling within such item) already deducted under section 43(1)(a) of the BCR; and (iii) include in the amount to be deducted under item (i)(iii) potential future holdings that the institution could be contractually obliged to purchase. In this connection, the HKMA will generally follow the applicable accounting treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the institution holding a capital position upon completion of the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the institution, it may treat the uncompleted transaction as not constituting a potential future holding.
72. The applicable amount to be deducted from the institution’s
Additional Tier 1 capital under paragraph 71 above should be determined by the formula in the first column of the following
table:

MA(BS)3(II)/P.26 (03/2025)
Applicable amount
Reference to Schedule
4F of the BCR
(For deduction of holdings by an institution that is a “section 2 institution” as defined in section 2 of Schedule 4F to the BCR 9 ) Excess(10% threshold)(net long) * AT1 percentage Sections 1, 2, 4 (For deduction of holdings by an institution that is a “section 3 institution” (within the meaning of section 3 of Schedule 4F to the BCR) or treated as such by virtue of section 2(2) of Schedule 4F) Excess(10% threshold)(net long) * AT1 percentage Sections 1, 3, 4
Annex II-D is an illustrative example on how to calculate the
applicable amount of insignificant and significant LAC investments to be deducted from CET1 capital, Additional Tier 1 capital and Tier 2 capital.
73. The amount of insignificant LAC investments issued by
financial sector entities that do not exceed the 10% threshold referred to in paragraph 72 above, and therefore not deducted from an institution’s Additional Tier 1 capital, is to continue to be risk-weighted in accordance with the applicable risk￾weight under one or more of Parts 4, 5, 6 and 8 of the BCR, as the case requires. (i)(iv) Significant LAC investments in Additional Tier 1 capital instruments issued by financial sector entities that are not subject to consolidation under a section 3C requirement
74. Subject to paragraph 75 below, report the amount of the
institution’s direct, indirect and synthetic holdings of Additional Tier 1 capital instruments issued by financial sector entities, calculated in accordance with Schedule 4G of the BCR, if – (a) the entities are not the subject of consolidation under a section 3C requirement imposed on the institution; (b) the holdings are significant LAC investments; and (c) the holdings do not otherwise fall within items (i)(i) and (i)(ii) above. For this purpose, the institution must:
(i) exclude holdings of capital instruments issued by financial sector entities that are not included within regulatory capital in the relevant financial sectors in which those entities operate;

(Viz., a resolution entity or material subsidiary but exclude any material subsidiary that has obtained the MA’s prior consent to be treated as a “section 3 institution” (within the meaning of section 3 of Schedule 4F)).

MA(BS)3(II)/P.27 (03/2025)
(ii) reduce the amount to be deducted under item (i)(iv) by any amount of goodwill (related to any holdings of Additional Tier 1 capital instruments falling within such item) already deducted under section 43(1)(a) of the BCR; and (iii) include in the amount to be deducted under item (i)(iv) potential future holdings that the institution could be contractually obliged to purchase. In this connection, the HKMA will generally follow the applicable accounting treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the institution holding a capital position upon completion of the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the institution, it may treat the uncompleted transaction as not constituting a potential future holding.
75. All significant LAC investments in capital instruments issued
by financial sector entities that are not in the form of CET1 capital instruments must be fully deducted from an authorized institution’s Additional Tier 1 capital or Tier 2 capital, as the case requires, by reference to the tier of capital for which the capital instruments would qualify if they were issued by the institution itself.
Annex II-D is an illustrative example on how to calculate the
applicable amount of insignificant and significant LAC investments to be deducted from CET1 capital, Additional Tier 1 capital and Tier 2 capital. (i)(v) Direct holdings of Additional Tier 1 capital instruments issued by financial sector entities that are members of the institution’s consolidation group
76. Item (i)(v) is applicable only for institution who calculates its
CAR on a solo/solo-consolidated basis under a section 3C requirement.
77. Report the amount of the institution’s direct holdings of
Additional Tier 1 capital instruments issued by financial sector entities that are members of the institution’s consolidation group. For this purpose, the institution must:
(i) exclude holdings of capital instruments issued by financial sector entities that are not included within regulatory capital in the relevant financial sectors in

MA(BS)3(II)/P.28 (03/2025) which those entities operate; (ii) reduce the amount to be deducted under item (i)(v) by any amount of goodwill (related to any holdings of Additional Tier 1 capital instruments falling within such item) already deducted under section 43(1)(a) of the BCR; and (iii) include in the amount to be deducted under item (i)(v) potential future holdings that the institution could be contractually obliged to purchase. In this connection, the HKMA will generally follow the applicable accounting treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the institution holding a capital position upon completion of the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the institution, it may treat the uncompleted transaction as not constituting a potential future holding. (i)(vi) Regulatory deductions applied to Additional Tier 1 capital due to insufficient Tier 2 capital to cover the required deductions
78. The institution is required to make from its Tier 2 capital any
regulatory deductions by virtue of section 48 of the BCR.
Such deductions must be applied to Additional Tier 1 capital in case Tier 2 capital of the institution is not sufficient to cover the required deductions.
79. If the institution’s Tier 2 capital before deductions (F) is less
than the sum of deduction items (r)(i) to (r)(viii), then:

• report “0” in Tier 2 capital after deductions (G); and
• report the sum of items (r)(i) to (r)(viii) minus Tier 2
  capital before deductions (F) in item (i)(vi).
  Additional Tier 1 Capital After Deductions (D)

80. This is the sum of items (g) and (h) in Column 2 after making
    the deductions specifically required from Additional Tier 1 capital (i.e. items (i)(i) to (i)(vi)). However, if an institution’s Additional Tier 1 capital before deductions (C) is less than the sum of deduction items (i)(i) to (i)(vi), then report “0” in Additional Tier 1 capital deductions (D) and follows the

MA(BS)3(II)/P.29 (03/2025) instructions set out in paragraph 56.
81. This is also the figure to be reported in item 1.1(ii) of Division
A of Form MA(BS)3(I).
Tier 1 Capital (E)
82. This is the sum of CET1 capital after deductions (B) and
Additional Tier 1 capital after deductions (D).

85. Tier 2 capital instruments issued to third parties by the
institution through a special purpose vehicle may be included in the Tier 2 capital of the institution on a consolidated basis as if the institution itself had issued the capital instruments to third parties, provided that:
(i) the special purpose vehicle is consolidated with the institution; (ii) the capital instruments meet the qualifying criteria set out in Schedule 4C of the BCR; and (iii) the only asset of the special purpose vehicle is its investment in the capital of the institution in a form that meets the Tier 2 Qualifying Criteria set out in Schedule 4C of the BCR 10 . (k) Applicable amount of capital instruments issued by the consolidated bank subsidiaries of the institution and held by third parties
86. Where the MA requires under section 3C of the BCR that the
CAR of the institution is to be calculated on a consolidated basis in respect of the institution’s bank subsidiaries, report in item (k) the applicable amount of capital instruments issued by the consolidated bank subsidiaries of the institution and held by third parties, which is recognized as Tier 2 capital of the institution on a consolidated basis, and calculated in accordance with sections 2(2) and 5 of Schedule 4D (Requirements to be Met for Minority Interests and Capital Instruments Issued by Consolidated Bank Subsidiaries and held by Third Parties to be included in Authorized Institution’s Capital Base) of the BCR.

87. The maximum amount of all capital instruments (i.e. CET1
capital instruments, Additional Tier 1 capital instruments and Tier 2 capital instruments) issued by the bank subsidiary to third parties that can be included in the Total capital of the institution on a consolidated basis is calculated as:
A – (B * C) where:
A gross amount of total qualifying capital instruments of the bank subsidiary issued to third parties B (If the bank subsidiary is incorporated in Hong Kong) surplus Total capital of the subsidiary = Total capital of the subsidiary (after taking into account items under section 38(2) and deductions under sections 43 to 48 of the BCR) less the lower of –

Note:
An institution may choose to use 8% (substitute percentage) instead of the specified minimum ratio referred to in items B.i.(I), B.ii.(I) and B.iii.(I) above. C percentage of total capital instruments of the subsidiary held by third parties
88. The amount of Total capital recognized in the Tier 2 capital of
an institution on a consolidated basis must exclude the portion that has been recognized in the consolidated Tier 1 capital under paragraphs 13 and 61 above.
89. The calculation as shown above must be undertaken for each
individual bank subsidiary separately. If the institution has chosen to use the substitute percentage, it must not, without the MA’s prior consent, use the specified minimum ratio subsequently. In addition, the institution must use only either the specified minimum ratio or the substitute percentage in respect of all the bank subsidiaries of the institution that are members of its consolidation group.
90. Annex II-A is an illustrative example on how to calculate the
applicable amount of minority interests and capital instruments issued by consolidated bank subsidiaries and held by third parties to be included in authorized institution’s capital base.
91. If the institution issues Tier 2 capital instrument to third
parties through a special purpose vehicle via a consolidated bank subsidiary and - (i) the special purpose vehicle is consolidated with the bank subsidiary; (ii) the capital instruments meet the Tier 2 Qualifying Criteria set out in Schedule 4C of the BCR; and (iii) the only asset of the special purpose vehicle is its investment in the capital of the bank subsidiary in a form that meets the Tier 2 Qualifying Criteria set out in Schedule 4C of the BCR 11 , the institution may treat the capital instruments as if the bank subsidiary itself had issued the capital instrument directly to third parties, and may include the capital instruments in

12 According to sections 29, 30 and 31 of the BCR, the institution is allowed to deduct the portion of reserves not recognized in Tier 2 capital (i.e. the amount of the 55% haircut) from the institution’s total risk￾weighted amount. Such deductible amount should be reported in item 2.12(ii) of Division A of Form MA(BS)3(I).

MA(BS)3(II)/P.35 (03/2025) endorsed in writing by an independent professional valuer; (e) any revaluation of the institution’s holdings of land and buildings is approved by the institution’s external auditors of the institution and explicitly reported in the institution’s audited accounts; and (f) the fair value gains relating to paragraphs 92(i) to (iii) above are recognized in accordance with applicable accounting standards and any such gains not recognized in the financial statements of the institution are excluded.

paragraphs 92(i) to (iii) above, which may be included in Tier 2 capital, shall not exceed 45% of each of such fair value gains (i.e. applying a haircut of 55% to each of such gains).
95. The institution must not, in calculating its Tier 2 capital, set￾off losses in respect of the institution’s own use land and
buildings where such losses are recognized in the institution’s profit or loss against unrealized gains that are reflected directly in the institution’s equity through the statement of changes in equity.
96. The institution must deduct from its CET1 capital any
cumulative losses of the institution arising from the institution’s holdings of land and buildings below the depreciated cost value (whether or not any such land and buildings are held for the institution’s own-use or for investment purposes). Such amount, if any, is to be reported in item (f)(xiv) above.

98. For an institution which uses only the STC approach or BSC
approach to calculate its credit risk for non-securitization exposures, the institution must– (i) report its regulatory reserve for general banking risks in item (m) and collective provisions in item (n); and (ii) report the total of items (m) and (n) in item (o) up to an amount not exceeding 1.25% of the institution’s aggregate risk-weighted amount for credit risk calculated by using the STC approach or BSC approach and by using any of the SEC-ERBA, SEC-SA and SEC-FBA. However, the risk-weighted amounts of exposures to CCPs, if any, are excluded.
99. For an institution which uses only the IRB approach, or a
combination of the STC approach and IRB approach, to calculate its credit risk for non-securitization exposures, the institution must– (i) apportion its regulatory reserve for general banking risks and collective provisions between the STC approach, IRB approach, SEC-IRBA, SEC-ERBA, SEC-SA and SEC-FBA in accordance with section 42(2)(a) or (b) of the BCR, as the case may be. However, the risk￾weighted amounts of exposures to CCPs, if any, are excluded for the operation of paragraph 99; and (ii) after it has carried out the apportionment referred to in sub-paragraph (i) above – (a) report its regulatory reserve for general banking risks apportioned to the STC approach, SEC￾ERBA, SEC-SA and SEC-FBA (relevant approaches) in item (m) and its collective provisions apportioned to the relevant approaches in item (n); (b) report the total of items (m) and (n) in item (o) up to an amount not exceeding 1.25% of its

(p) Surplus provisions (for exposures calculated by using IRB approach)
100. For the institution that adopts the IRB approach for credit risk,
if its total EL amount is less than its total eligible provisions, the institution may include the amount of the excess of the total eligible provisions over the total EL amount (i.e. the surplus provisions) in its Tier 2 capital up to 0.6% of its risk￾weighted amount for credit risk calculated by using the IRB approach (that is to say, the credit RWA should exclude risk￾weighted amountsfor exposures to CCPs, if any). The amount to be reported in item (p) of Part II should be consistent with the figure reported in item 9 of Division F of Form MA(BS)3(IIIc).

(r)(i) Investments in own Tier 2 capital instruments
104. Report the amount of any direct, indirect and synthetic
holdings by the institution of its own Tier 2 capital instruments, unless already derecognized under applicable accounting standards, calculated in accordance with the requirements specified in Schedule 4E of the BCR. For this purpose, the institution must:
(i) exclude holdings of capital instruments issued by financial sector entities that are not included within regulatory capital in the relevant financial sectors in which those entities operate; and (ii) include in the amount to be deducted under item (r)(i) potential future holdings that the institution could be contractually obliged to purchase. In this connection, the HKMA will generally follow the applicable accounting treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the institution holding a capital position upon completion of the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the institution, it may treat the uncompleted transaction as not constituting a potential future holding.

MA(BS)3(II)/P.39 (03/2025)
(ii) include in the amount to be deducted under item (r)(ii) potential future holdings that the institution could be contractually obliged to purchase. In this connection, the HKMA will generally follow the applicable accounting treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the institution holding a capital position upon completion of the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the institution, it may treat the uncompleted transaction as not constituting a potential future holding. (r)(iii) Insignificant LAC investments in Tier 2 capital instruments issued by and non-capital LAC liabilities of financial sector entities that are not subject to consolidation under a section 3C requirement and not covered by either the 5% or the 10% threshold
106. Subject to paragraph 107 below, report the applicable amount
of the institution’s direct, indirect and synthetic holdings of Tier 2 capital instruments issued by and non-capital LAC liabilities of financial sector entities, calculated in accordance with Schedule 4F of the BCR, if – (a) the entities are not the subject of consolidation under a section 3C requirement imposed on the institution (or not within the same banking group as the institution in the case of holdings of non-capital LAC liabilities); (b) the holdings are insignificant LAC investments; and (c) the holdings do not otherwise fall within items (r)(i) and (r)(ii) above. For this purpose, the institution must:
(i) exclude holdings of capital instruments issued by financial sector entities that are not included within regulatory capital in the relevant financial sectors in which those entities operate; and (ii) include in the amount to be deducted under item (r)(iii) potential future holdings that the institution could be contractually obliged to purchase. In this connection, the HKMA will generally follow the applicable accounting treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the institution holding a capital position upon completion of the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the

MA(BS)3(II)/P.40 (03/2025) institution, it may treat the uncompleted transaction as not constituting a potential future holding.
107. The applicable amount to be deducted from the institution’s
Tier 2 capital under paragraph 106 above should be determined by the formula in the first column of the following
table:

  Annex II-D is an illustrative example on how to calculate the
  applicable amount of insignificant and significant LAC investments to be deducted from CET1 capital, Additional Tier 1 capital and Tier 2 capital.

108. The amount of insignificant LAC investments issued by
     financial sector entities that do not exceed the 10% threshold or the 5% threshold referred to in paragraph 107 above and therefore not deducted from an institution’s Tier 2 capital, is continue to be risk-weighted in accordance with the applicable risk weight under one or more of Parts 4, 5, 6 and 8 of the BCR, as the case requires.

110. For avoidance of doubt, the holdings in the institution’s
investments in non-capital LAC liabilities which have been designated under section 2(3)(a) of Schedule 4F to the BCR must not subsequently be included within the 10% threshold under paragraph 107. (r)(v) Significant LAC investments in Tier 2 capital instruments issued by financial sector entities that are not subject to consolidation under a
section 3C requirement
111. Subject to paragraph 112 below, report the amount of the
institution’s direct, indirect and synthetic holdings of Tier 2 capital instruments issued by financial sector entities, calculated in accordance with Schedule 4G of the BCR, if – (a) the entities are not the subject of consolidation under a
section 3C requirement imposed on the institution; (b) the
holdings are significant LAC investments; and (c) the holdings do not otherwise fall within items (r)(i) and (r)(ii) above. For this purpose, the institution must:
(i) exclude holdings of capital instruments issued by financial sector entities that are not included within regulatory capital in the relevant financial sectors in which those entities operate; and (ii) include in the amount to be deducted under item (r)(v) potential future holdings that the institution could be contractually obliged to purchase. In this connection, the HKMA will generally follow the applicable accounting treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the institution holding a capital position upon completion of the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the institution, it may treat the uncompleted transaction as not constituting a potential future holding.
112. All significant LAC investments in capital instruments issued
by financial sector entities that are not in the form of CET1 capital instruments must be fully deducted from an institution’s Additional Tier 1 capital and Tier 2 capital, as the case requires, by reference to the tier of capital for which the

MA(BS)3(II)/P.42 (03/2025) capital instruments would qualify if they were issued by the institution itself.
Annex II-D is an illustrative example on how to calculate the
applicable amount of insignificant and significant LAC investments to be deducted from CET1 capital, Additional Tier 1 capital and Tier 2 capital. (r)(vi) Significant LAC investments in non-capital LAC liabilities of financial sector entities that are not subject to consolidation under a
section 3C requirement
113. Report the amount of the institution’s direct, indirect and
synthetic holdings of non-capital LAC liabilities of financial sector entities, calculated in accordance with Schedule 4G of the BCR, if – (a) the entities are neither the subject of consolidation under a section 3C requirement imposed on the institution nor within the same banking group as the institution; (b) the holdings are significant LAC investments; and (c) the holdings do not otherwise fall within item (r)(ii) above.
114. For this purpose, the institution must include in the amount to
be deducted under item (r)(vi) potential future holdings that the institution could be contractually obliged to purchase. In this connection, the HKMA will generally follow the applicable accounting treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the institution holding a capital position upon completion of the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the institution, it may treat the uncompleted transaction as not constituting a potential future holding. (r)(vii) Direct holdings of Tier 2 capital instruments issued by financial sector entities that are members of the institution’s consolidation group
115. Item (r)(vii) is applicable only for institution who calculates
its CAR on a solo/solo-consolidated basis under a section 3C requirement.
116. Report the amount of the institution’s direct holdings of Tier
2 capital instruments issued by financial sector entities that are members of the institution’s consolidation group. For this purpose, the institution must:

MA(BS)3(II)/P.43 (03/2025)
(i) exclude holdings of capital instruments issued by financial sector entities that are not included within regulatory capital in the relevant financial sectors in which those entities operate; and (ii) include in the amount to be deducted under item (r)(vii) potential future holdings that the institution could be contractually obliged to purchase. In this connection, the HKMA will generally follow the applicable accounting treatment. In case there are areas where the regulatory treatment is different from the accounting treatment, the HKMA will consider each scenario on a case by case basis. The general principle is that if a transaction is subject to conditions precedent which will lead to the institution holding a capital position upon completion of the transaction where the fulfilment of any of the outstanding conditions is beyond the control of the institution, it may treat the uncompleted transaction as not constituting a potential future holding. (r)(viii) Regulatory deductions applied to Tier 2 capital to cover the required deductions falling within section 48(1)(g) of BCR
117. For institution that maintains any non-capital LAC debt
resources, report the amount by which the total amount of the institution’s holdings of non-capital LAC liabilities falling within section 48A of the BCR exceeds the institution’s non￾capital LAC debt resources. Those holdings of non-capital LAC liabilities that are not deducted from the institution’s Tier 2 capital is to continue to be risk-weighted in accordance with the applicable risk-weights under one or more of Parts 4, 5, 6 and 8, as the case requires.
118. For institution that does not maintain any non-capital LAC
debt resources, report the total amount of the institution’s holdings of non-capital LAC debt liabilities falling within
section 48A of the BCR.
Tier 2 Capital After Deductions (G)
119. This is the sum of items (j), (k), (l), (o) (p) and (q) in Column
2 after making the deductions specifically required from Tier 2 capital (i.e. items (r)(i) to (r)(viii)).
120. If the institution’s Tier 2 capital before deductions (F) is less
than the sum of deduction items (r)(i) to (r)(viii), then:

• report “0” in Tier 2 capital after deductions (G); and

MA(BS)3(II)/P.44 (03/2025)

• report the sum of items (r)(i) to (r)(viii) minus Tier 2
  capital before deductions (F) in item (i)(vi).

Annex II-A
Illustrative example to calculate the applicable amount of minority interests / Additional Tier 1 and Tier 2 capital instruments issued by consolidated bank subsidiaries and held by third parties to be recognized in CET1 capital, Additional Tier 1 capital and Tier 2 capital of an authorized institution Suppose a bank subsidiary (Bank S) issued ordinary shares, Additional Tier 1 and Tier 2 capital instruments of $100, $40 and $20 respectively, and third parties own 30% of the ordinary share, 50% of Additional Tier 1 capital instruments and 75% of Tier 2 capital instruments. If Bank S has $1,000 of total risk-weighted assets, its minimum CET1, Tier 1 and total capital requirements (including applicable buffer level 1 ) are assumed to be $90, $105 and $125 (i.e. corresponding to a 9% CET1 capital ratio, 10.5% Tier 1 capital ratio and a 12.5% Total capital ratio) 2 respectively. Therefore, the applicable amount of minority interests is calculated as follows:
(a) (b) (c) (d) (e) (f) (g) (h)
Capital issued by
Bank S
(gross of regulatory deductions)
Capital owned by third parties
Amount of minority interests
Minimum capital ratio (incl. applicable buffer level) Minimum capital requirement (incl. applicable buffer level) Surplus capital of subsidiary (net of deductions, if any) Surplus capital of subsidiary attributable to third parties Minority interests recognized = ((a) * (b)) = (RWA * (d)) = ((a) – (e)) =((f) * (b)) = ((c) – (g)) CET1 $100 30% $30 9% $90 $10 $3 $27 AT1 $40 50% $20 $10.5 Tier 1 $140 35.7% $50 10.5% $105 $35 $12.5 $37.5 Tier 2 $20 75% $15 $13.3 Total capital $160 40.6% $65 12.5% $125 $35 $14.2 $50.8 C A B

1 Assuming buffer level applicable under section 3G of the BCR is 4.5%, consisting of 2.5% capital conservation buffer, 1% countercyclical capital buffer and 1% higher loss absorbency requirement. 2 The three percentage figures here are for illustrative purposes only. The exact figures to be used in reality will depend on whether Bank S is locally incorporated in Hong Kong or outside Hong Kong according to Schedule 4D of the BCR.

MA(BS)3(II) Annex/P.2 (03/2025)
In this example, by using the formula [A – (B * C)] as stipulated in paragraph 13 of the completion instructions, the amount of minority interest that can be recognized in the institution’s consolidated CET1 capital is $27 (i.e. $30 – ($10 * 30%)). Similarly, following the same formula above, the amount of Tier 1 capital instruments (including both CET1 and AT1 capital instruments) held by third parties that can be recognized in the institution’s consolidated Tier 1 capital equals to $37.5 (i.e. $50 – ($35 * 35.7%)). Since $27 has been recognized in the consolidated CET1 capital of the institution, only $10.5 (i.e. $37.5 - $27) of such Tier 1 capital instruments can be included in its consolidated Additional Tier 1 capital. The calculation of the applicable amount of Tier 2 capital instruments held by third parties to be included in an institution’s Tier 2 follows the same methodology as shown above.

Annex II-C
Regulatory Treatment of Expected Loss Provisions under Hong Kong Financial Reporting Standard 9 (HKFRS 9) Basel Committee on Banking Supervision (BCBS) interim standard

1. The BCBS regulatory capital standard requires banks to categorize accounting provisions
   made into general provisions (GP) and specific provisions (SP) for the purpose of capital treatment. Authorized institutions (AIs) using the standardised approach and basic approach for credit risk can include GP as Tier 2 capital up to 1.25% of credit RWAs while SP are netted off from risk-weighted exposures. For AIs using the IRB approach, the total eligible provisions (EP) (which include all accounting provisions) are compared with the regulatory measure of expected loss (EL) calculated based on predetermined parameters. Any shortfall of EP vis-a-vis EL is deducted from CET1 capital, and any excess of EP over EL is counted as Tier 2 capital up to 0.6% of credit RWAs.
2. As an interim measure for capital adequacy purposes pending the design and development
   of a longer-term solution, the BCBS issued on 29 March 2017 an interim standard on the regulatory treatment of accounting provisions 3 , under which the current requirement to categorise banks’ provisions into GP and SP and their respective treatment for regulatory capital calculation (as mentioned in paragraph 1 above) will remain unchanged when the “expected loss” provisioning model under International Financial Reporting Standard 9 (IFRS 9) comes into effect from 1 January 2018. Capital treatment of expected loss provisions under the Banking (Capital) Rules (BCR)
3. To align with the expected loss provisions under the new HKFRS 9 (IFRS 9 equivalent),
   existing definitions for “collective provisions” (i.e. essentially GP) and “specific provisions” set out in section 2(1) of the BCR have been updated. The HKFRS 9 categories financial assets into three stages in terms of credit impairment. For capital calculation, impairment provisions pertaining to exposures classified under the first two stages (i.e. Stage 1 and Stage 2) will be treated as GP, and those pertaining to exposures classified under Stage 3 as SP. With respect to provisions made for purchased or originated credit-impaired financial assets under which any changes in lifetime expected credit losses will be recognized in profit or loss account as an impairment gain or loss, the HKMA regards that such provisions to be similar in nature to SP and hence will be treated as such for capital adequacy purposes. Determination of Regulatory Reserve (RR) under HKFRS 9
4. The following two-step approach should be adopted for determining whether any RR is
   required to be maintained by an AI on top of the provisions made by it under the new accounting standard (please refer to the HKMA’s consultation paper “Regulatory Treatment of Provisions under HKFRS 9” (CP 17.02) 4 for details):

3 http://www.bis.org/bcbs/publ/d401.pdf Following the issuance of the interim standard, the BCBS continues to work on the development of a final standard to reflect expected loss provisioning within the regulatory capital framework. 4 The consultation paper is available at http://www.hkma.gov.hk/media/eng/doc/key-functions/banking￾stability/basel-3/CP_17_02_HKFRS9.pdf

MA(BS)3(II) Annex/P.5 (03/2025)
(a) Step 1 – calculating a benchmark regulatory provision for unidentified expected loss (benchmark) for each AI as the product of (i) a predetermined institution￾specific “target rate” of the AI 5 and (ii) the AI’s total loans and advances (to non￾banks) 6 ; (b) Step 2 – comparing the benchmark with the relevant portion of HKFRS 9 provisions made for the AI’s total loans and advances to non-banks categorised into Stage 1 and Stage 2 under HKFRS 9 which, by definition, are not credit￾impaired (i.e. they are provisions for unidentified expected loss); and (i) where the benchmark is greater than the relevant portion of HKFRS 9 provisions, the “shortfall” will continue to be earmarked from retained earnings and maintained as RR; (ii) where, on the other hand, the benchmark is equal to or smaller than relevant portion of HKFRS 9 provisions so that there is no “shortfall” or an “excess” of accounting provisions, no RR will be required.

5 Please also refer to any circulars issued by the HKMA for the latest announcement in relation to the RR calculation mechanism including the one issued on 8 April 2020 (which is available at https://www.hkma.gov.hk/media/eng/doc/key-information/guidelines-and-circular/2020/20200408e1.pdf, https://www.hkma.gov.hk/media/eng/doc/key-information/guidelines-and-circular/2020/20200408e1a1.pdf). 6 Exposures arising from IPO financing which fall within sections 64A, 113A or 202B of the BCR are excluded from the base in calculating regulatory reserve.

Steps Calculations

1. Determine the 10% and 5% concessionary threshold

• Less: deductions
  CET1 capital after deductions 8
  $7,000
  ($1,000)
  $6,000
  5% concessionary threshold:
  = $6,000 * 5%
  = $300 (f)
  10% concessionary threshold:
  = $6,000 * 10%
  = $600 (g)

2. Determine the amount of investments in NCLAC that are
   currently designated under section 2(3)(a) of Schedule 4F but are in excess of the 5% threshold (i.e. “Excess(5% threshold)(gross long)”) = ((e) – (f)) = $350 - $300 = $50 Not applicable
3. Determine the total amount of investments in capital
   instruments and NCLAC on a net long basis that will be covered by or exceed the 10% threshold Not applicable = (a) + (b) + (c) + (d) = $650 + $400 + $300 + $200 = $1,550 (h)
4. Determine the amount of investments in capital instruments
   and NCLAC that are in excess of the 10% threshold (i.e.
   “Excess(10% threshold)(net long)”
   Not applicable
   = ((h) – (g))
   = $1,550 - $600
   = $950
   4a. Apportion the amount of investments in CET1 capital instruments to be deducted from CET1 capital Not applicable = $950* ($650 / $1,550) = $398 4b. Apportion the amount of investments in AT1 capital instruments to be deducted from AT1 capital Not applicable = $950 * ($400 / $1,550) = $245

8 The CET1 capital after deductions for the calculation of the 10% and 5% threshold must take into account any deduction applied to CET1 capital due to insufficient AT1 capital and T2 capital, if any.

MA(BS)3(II) Annex/P.8 (03/2025)
4c. Apportion the amount of (i) investments in T2 capital instruments and (ii) investments in NCLAC that are neither currently designated under section 2(3)(a) of Schedule 4F nor were formerly designated (i.e. “Inv(NvDsg NCLAC")” to be deducted from T2 capital Not applicable = $950 * (($300 + $200) / $1,550) = $307 Consequently, Bank A’s holding of insignificant LAC investments in excess of 10% concessionary threshold is $950, being $1,550 minus $600. The pro-rata calculation of respective amounts subject to (i) deduction from each tier of capital, and (ii) risk-weighting in accordance with the applicable risk-weights under one or more of Parts 4, 5, 6 and 8 of the BCR, as the case requires, will be as follows –
Table 1
(A)
Amount subject to deduction Amount subject to risk-weighting Total from CET1 = $950 * ($650/$1,550) = $398 = $600 * ($650/$1,550) = $252 $650 from AT1 = $950 * ($400/$1,550) = $245 = $600 * ($400/$1,550) = $155 $400 from T2 = $950 * (($300 + $200)/$1,550) = $307 = $600 * (($300 + $200)/$1,550) = $193 $500 $950 $600 $1,550

MA(BS)3(II) Annex/P.9 (03/2025)
Hence, the balance of CET1 capital, AT1 capital and T2 capital of Bank A after the deduction of insignificant LAC investments in Part I will be –

Part II (significant LAC investments)
According to sections 1(2), (3) and (3A) of Schedule 4G to the BCR, with respect to significant LAC investments, the concessionary threshold only applies to the institution’s capital investments in the form of CET1 capital instruments. Any holdings of AT1 capital instruments and T2 capital instruments issued by and non-capital LAC liabilities of financial sector entities must be fully deducted from the institution’s AT1 capital or T2 capital.

Basic Approach
Form MA(BS)3(IIIa)
Introduction

1. Form MA(BS)3(IIIa) of Part III should be completed by each authorized institution (AI)
   incorporated in Hong Kong using the basic approach (BSC approach) to calculate credit risk under Part 5 of the Banking (Capital) Rules (BCR).
2. This Form covers the following exposures of a reporting AI:
   (a) all on-balance sheet exposures and off-balance sheet exposures booked in its banking book; (b) all default risk exposures to counterparties under securities financing transactions (SFTs) and derivative contracts booked in its trading book; (c) all credit exposures to counterparties in respect of transactions (other than repo￾style transactions) in securities, foreign exchange or commodities booked in its trading book that remain outstanding after the settlement dates in respect of the transactions; (d) all credit exposures to counterparties in respect of unsegregated collateral posted by the AI and held by the counterparties for transactions or contracts booked in AI’s trading book; and (e) if applicable, the AI’s market risk positions that are exempted from section 17 under section 22 of the BCR, except for its total net open position in foreign exchange exposures as derived in accordance with section 296 of the BCR.
3. This Form does not cover the following exposures:
   (a) portions of exposures (which may be all of the exposures) that are required to be deducted from any of the AI’s CET1 capital, Additional Tier 1 capital and Tier 2 capital under Division 4 of Part 3 of the BCR (which should be reported in Form MA(BS)3(II)); (b) securitization exposures (which should be reported in Form MA(BS)3(IIId)); (c) the underlying exposures of eligible traditional securitization transactions if the AI opts to apply the treatment under section 230(1) of the BCR to the underlying exposures; (d) default fund contributions made to qualifying CCPs and non-qualifying CCPs (which should be reported in Form MA(BS)3(IIIe));

MA(BS)3(IIIa)/P.2 (03/2025)
(e) default risk exposures to qualifying CCPs (which should be reported in Form MA(BS)3(IIIe)); and (f) exposures that are risk-weighted as if they were default risk exposures to qualifying CCPs under Division 4 of Part 6A (which should be reported in Form MA(BS)3(IIIe)).
4. This Form and these completion instructions should be read in conjunction with the
BCR and the relevant supervisory policy/guidance related to the capital adequacy framework.
Section A: Definitions and Clarification
5. In these instructions⸺
(a) “gross sum of the stated notional amounts” refers to the sum of the stated notional amounts of all relevant contracts, without the stated notional amounts of contracts with positive replacement costs being reduced by the stated notional amounts of contracts with negative or zero replacement costs, regardless of whether the contracts are subject to recognized netting. (b) “recognized CRM” refers to recognized collateral, recognized netting, recognized guarantees and recognized credit derivative contracts. To avoid doubt, guarantees issued by other offices of the reporting AI are not regarded as recognized credit risk mitigation. Debt securities which are re-securitization exposures (whether rated or not) cannot be recognized as collateral (see section 125(2) of the BCR). (c) “stated notional amount” means the nominal notional amount of a derivative contract. It should not be confused with any effective notional amount or adjusted notional calculated for the derivative contract under Part 6A of the BCR. (d) “Tier 1 country” has the meaning given by the Banking Ordinance, that is, Hong Kong and any country or place other than Hong Kong which⸺ (i) is a member of the Organization for Economic Co-operation and Development (OECD); or (ii) has concluded special lending arrangements with the International Monetary Fund associated with the International Monetary Fund’s General Arrangements to Borrow, but excludes any such country or place which⸺ (iii) has rescheduled its external sovereign debt, whether to central government or non-central government creditors, within the previous five years; or (iv) is specified by the Monetary Authority (MA) by notice published in the Gazette as being a country or place that is not to be regarded as a Tier 1 country for the purposes of this definition.

6. AIs and banks include their head offices and branches outside Hong Kong. For
example, a placement with a Tier 2 country incorporated AI or its branch outside Hong Kong should be classified as an exposure to an AI regardless of the jurisdiction of its incorporation or location of its branch. A placement with a Tier 1 country incorporated bank’s branch, regardless of its location, should be classified as an exposure to a bank incorporated in Tier 1 country.
7. Double counting of exposures arising from the same contract or transaction should be
avoided. For example, only the undrawn portion of a loan commitment should be reported as an off-balance sheet exposure while the actual amount which has been lent out should be reported as an on-balance sheet exposure. Trade-related contingencies, such as trust receipts and shipping guarantees, which have already been reported as letters of credit issued or loans against import bills etc. should not be counted again as off-balance sheet exposures.
8. In certain cases, exposures to counterparties arising from derivative contracts entered
into by the reporting AI with those counterparties may already be reflected, in part, on the reporting AI’s balance sheet. For example, the AI may have recorded the fair value of a derivative contract on its balance sheet. To avoid double counting, such amount should be excluded from on-balance sheet exposures and treated as off-balance sheet exposures for the purposes of this Form.
9. Accruals on an exposure should be classified and risk-weighted in the same way as the
exposure. Accruals which cannot be so classified should, with the prior consent of the MA, be included in Class XII (Other Exposures).

1 The list is provided for reference only and may not be up-to-date. AIs must visit the website of the OECD (https://www.oecd.org) regularly to verify whether a sovereign to which the AIs have exposures is an OECD member.

MA(BS)3(IIIa)/P.4 (03/2025)
10. For specified SFTs booked in the reporting AI’s banking book⸺
(a) if the assets underlying the SFTs are non-securitization exposures, the AI’s credit exposures to the assets underlying the SFTs should be reported in Division A of this Form (see also section 117C(2) of the BCR); (b) if the assets underlying the SFTs are securitization exposures, the AI’s credit exposures to the assets underlying the SFTs should be risk-weighted in accordance with Part 7 of the BCR and reported in Form MA(BS)3(IIId) (see also section 117C(3) of the BCR).
11. For specified SFTs booked in the reporting AI’s trading book, the AI’s exposures to the
assets underlying the SFTs are market risk exposures. Hence, the AI only needs to calculate the risk-weighted amounts (RWAs) of its market risk exposures to the assets in accordance with Part 8 of the BCR (see section 117C(4) of the BCR) and reports the exposures in the corresponding Return Form for market risk. The AI is not required to calculate any RWA for the credit risk of the assets. However, if the AI is granted an exemption under section 22 of the BCR, the AI should comply with section 117C(2) instead of section 117C(4) of the BCR in calculating the RWAs of its exposures to the assets, and report the exposures in this Form instead.
12. An originating institution of a non-eligible securitization transaction must report the
RWA of the underlying exposures of the transaction in this Form as if the exposures were not securitized. If the credit risk mitigation (CRM) afforded to the underlying exposures of an eligible synthetic securitization transaction is not in the form of tranched credit protection, the underlying exposures must be reported in this Form in the same manner as a non-eligible securitization transaction except that the CRM for transferring the credit risk of the underlying exposures to the other parties to the transaction can be taken into account in the RWA calculation and therefore should also be included in the reporting. However, if the CRM is in the form of tranched credit protection, both the underlying exposures and the CRM effect must be reported in Form MA(BS)3(IIId) (please see paragraph 15(b) of the completion instructions for Form MA(BS)3(IIId)). For cases which are not specified in these instructions or in any other supervisory guidance relevant to securitization transactions, reporting AIs should consult the HKMA on the reporting arrangements.
Section B: Reporting arrangements for Division A of Part IIIa
B.1 Exposure Classification
13. Division A of this Form is organized according to the following standard exposure
classes into which on-balance sheet and off-balance sheet exposures should be classified under the BSC approach:
Class I Sovereign Exposures
Class II Public Sector Entity (PSE) Exposures Class III Multilateral Development Bank (MDB) Exposures Class IV Unspecified Multilateral Body Exposures Class V Bank Exposures Class VI Eligible Covered Bond Exposures

MA(BS)3(IIIa)/P.5 (03/2025)
Class VII IPO Financing
Class VIII Cash and Gold
Class IX Exposures to Items in the Process of Clearing or Settlement Class XA Regulatory Residential Real Estate Exposures Class XB Other Real Estate Exposures Class XIA Equity Exposures Class XIB Significant Capital Investments in Commercial Entities Class XIC Insignificant and Significant LAC Investments Class XID Subordinated Debts Class XII Other Exposures Class XIII Collective Investment Scheme Exposures (CIS exposures)
14. The exposure classes are mutually exclusive and therefore each exposure should be
reported under only one of them. However, it should be noted that a single transaction may give rise to more than one exposure. For example, a derivative contract booked in the banking book has an exposure to the counterparty to the derivative contract and may also have a credit exposure to the asset underlying the derivative contract.
15. Classification of credit-linked notes (CLNs) held
(a) A single-name CLN held by the reporting AI should be reported in Division A under⸺ (i) the exposure class applicable to the issuer of the CLN if the CLN is allocated the risk-weight determined by risk-weighting the CLN as an exposure to the issuer; or (ii) the exposure class applicable to the reference obligation of the CLN if the CLN is allocated the risk-weight attributable to the reference obligation. (b) A multiple-name CLN (e.g. a first-to-default CLN) should be reported in Class XII item 12c.
16. Classification of off-balance sheet exposures
Off-balance sheet exposures must be classified into exposure classes in the same manner as on-balance sheet exposures (i.e. based on the source of credit risk). In particular— (a) in the case of an asset sale with recourse, a sale and repurchase agreement (other than a repo-style transaction) or a forward asset purchase, since the credit risk is arising from the asset that could be repurchased or is to be purchased in the future, the exposure should be classified into the exposure class within which the asset sold/to be purchased (e.g. equities) would fall if the asset were held by the reporting AI; (b) in the case of partly paid-up shares and securities, since the credit risk associated with the shares or securities is in effect passed to the reporting AI, the exposure should be classified into the exposure class within which the relevant shares or securities would fall if they were on-balance sheet exposures of the reporting AI;

MA(BS)3(IIIa)/P.6 (03/2025)
(c) in the case of a direct credit substitute arising from the selling of credit protection in the form of total return swap or credit default swap booked in the reporting AI’s banking book, the exposure should be classified into the exposure class within which the relevant reference obligation of the swap would fall if the reference obligation were an on-balance sheet exposure of the reporting AI. If the swap provides credit protection to a basket of reference obligations, the exposure should be classified into Class XII; and (d) in the case of default risk exposures, the exposures should be classified into the exposure classes within which the counterparties to the derivative contracts or SFTs concerned fall. B.2 Specific Instructions for Selected Exposure Classes
17. Class I Sovereign Exposures
(a) Deposits placed with, and loans made to, the Government (including those for the account of the Exchange Fund and the clearing balances with the Exchange Fund) should be reported in item 1a. (b) Market makers who have short positions in Exchange Fund Bills/Notes may report their net holdings of such instruments provided that the short positions are covered by the Sale and Repurchase Agreements with the HKMA. The following steps should be taken in determining the amount to be reported:
(i) the long and short positions of instruments with a residual maturity of less than 1 year may be offset with each other; (ii) the long and short positions of instruments with a residual maturity of not less than 1 year may be offset with each other; (iii) if the net positions of both (i) and (ii) above are long, the positions should be reported in items 1b and 1c respectively; (iv) if the net positions in (i) is long and the net position in (ii) is short, or the other way round, the two positions can be netted with each other on a dollar for dollar basis. The resultant net long position, if any, should be reported in item 1b or 1c as appropriate. (c) An off-balance sheet exposure to a sovereign may be reported in item 1b, 1c, 1d, 1e, 1g, 1h, 1i or 1j only if it is a credit exposure arising from fixed rate or floating rate debt securities issued or guaranteed by the sovereign, e.g. a forward asset purchase to buy a fixed rate government bond.

MA(BS)3(IIIa)/P.7 (03/2025)
18. Class V Bank Exposures
For the purposes of this exposure class, clean 2 export trade bills negotiated under other banks’ letters of credit may be reported as exposures to the issuing banks of the letters of credit.
19. Class VII IPO Financing
Only exposures arising from IPO financing that are eligible for 0% risk-weight are reported in this exposure class. After payments for allotted securities are made to the relevant receiving bank, any outstanding loan amounts should be reported in the exposure classes to which the obligors belong (e.g. Class XII if the obligor is an individual).
20. Class VIII Cash and Gold
(a) Items 8c to 8e - Gold bullion
(i) Gold bullion held in safe custody for other entities or customers, which does not expose the reporting AI to any credit risk, is not required to be included in this Form. (ii) Gold bullion held on an unallocated basis by a third party for the reporting AI backed by gold liabilities should be reported in item 8d. Column A5 of item 8d is for reporting the weighted average of the attributed risk-weights of the third parties. (iii) Gold bullion held not backed by gold liabilities (i.e. all other holdings of gold bullion not included in items 8c and 8d) should be reported in item 8e. (b) Item 8f – Exposures collateralized by cash collateral (i) This item captures exposures collateralized by the following assets (collectively referred to as “cash collateral”)⸺ (A) cash on deposit with the reporting AI; or (B) certificates of deposit, or comparable instruments, issued by the reporting AI. (ii) However, when the cash collateral is held at a third-party bank in a non￾custodial arrangement and unconditionally and irrevocably pledged or assigned to the reporting AI, the credit protection covered portion concerned must be reported as an exposure to that third-party bank under Class V and therefore must not be reported in item 8f.

2 This includes cases where discrepancies have been accepted by the issuing bank concerned.

MA(BS)3(IIIa)/P.8 (03/2025)
21. Class IX Exposures to Items in the Process of Clearing or Settlement
(a) Item 9c refers to the amount of cheques, drafts and other items drawn on other banks that are payable to the account of the reporting AI immediately upon presentation and in the process of collection, and includes— (i) cheques and drafts against which the AI has paid to its customers (i.e. by purchasing or discounting the cheques or drafts presented by the customers) and in respect of which it now seeks payment from the drawee banks; but excludes— (ii) import and export trade bills held by the AI that are in the process of collection (they should be risk-weighted and reported as exposures to the counterparties concerned); (iii) unsettled clearing items that are being processed through any interbank clearing system in Hong Kong (which should be reported in item 9a); and (iv) receivables arising from transactions in securities (other than repo-style transactions), and transactions in foreign exchange and commodities, that are not yet due for settlement (which should be reported in item 9b). (b) Item 9d captures any transaction in securities (other than repo-style transaction), or any transaction in foreign exchange or commodities, that is entered into on a delivery-versus-payment (DvP) basis 3 where payment / delivery has not yet taken place after the settlement date. (c) Item 9e captures any transaction in securities (other than repo-style transaction), or any transaction in foreign exchange or commodities, that is entered into on a non￾DvP basis where payment / delivery from the counterparty concerned has not yet taken place after the settlement date. The amount of the payment made or the current market value of the thing delivered by the reporting AI, plus any positive current exposure associated with the transaction, should be reported as an exposure in item 9e(i) or (ii), as the case requires. The amount reported in item 9e(i) should be risk-weighted as a loan to the counterparty to the transaction.
22. Class XA Regulatory Residential Real Estate Exposures
(a) Regulatory residential real estate exposures that are risk-weighted in accordance with section 115B of the BCR should be reported in items 10a(i) to 10b(iii). (b) Real estate exposures (other than ADC exposures) secured by residential properties outside Hong Kong that are risk-weighted in accordance with section 115C of the BCR, where the exposures are regulatory residential real estate exposures under the capital adequacy standards of the jurisdictions concerned, should be reported in item 10c.

3 DvP transactions include payment-versus-payment (PvP) transactions.

MA(BS)3(IIIa)/P.9 (03/2025)
(c) See paragraph 29(d) for the reporting arrangement of regulatory residential real estate exposures guaranteed by Hong Kong Housing Authority or insured by HKMC Insurance Limited.
23. Class XB Other Real Estate Exposures
(a) ADC exposures should be reported in item 10d.
(b) Real estate exposures (other than ADC exposures) that are risk-weighted in accordance with section 115D of the BCR should be reported in item 10e. (c) Real estate exposures (other than ADC exposures) secured by residential properties outside Hong Kong that are risk-weighted in accordance with section 115C of the BCR, where the exposures are not regulatory residential real estate exposures under the capital adequacy standards of the jurisdictions concerned, should be reported in item 10f.
24. Class XIC Insignificant and Significant LAC Investments
(a) Items 11g(i) and 11g(iii) – Significant LAC investments Items 11g(i) and 11g(iii) are intended for reporting instruments that can be excluded from the calculation of the applicable amount mentioned in section 47(1)(d) and section 48(1)(d) of the BCR (e.g. capital instruments mentioned in
section 47(2)(a) and section 48(2)(a) of the BCR, and underwriting positions
mentioned in section 1(4)(c) of Schedule 4G to the BCR), where the risk-weight applicable to the instruments is not 250%. (b) Item 11h – Holdings of non-capital LAC liabilities This item is for reporting holdings that fall within section 115G(3) of the BCR. (c) Apart from the holdings that are risk-weighted in accordance with section 115G of the BCR, CIS exposures (or any part of the exposures) to which section 117F(3) of the BCR applies must also be reported under this exposure class.
25. Class XII Other Exposures
Included in this exposure class are exposures— (a) that are subject to credit risk capital requirements; and (b) that have not been included in Classes I to XI and Class XIII in this Form. Item no. Nature of item 12a. Exposures to corporates or individuals not elsewhere reported This refers to exposures to corporates or individuals that have not been included in other exposure classes and items 12c to 12f below.

MA(BS)3(IIIa)/P.10 (03/2025)
12b. Premises, plant and equipment, other fixed assets for own use, and other interest in land Included are— (a) investments in premises, plant and equipment and all other fixed assets of the reporting AI which are held for own use; a right-of-use asset recognized by the reporting AI as a lessee in accordance with the prevailing accounting standards issued by Hong Kong Institute of Certified Public Accountants where the asset leased is a tangible asset; and (b) other interests in land which are neither occupied by the reporting AI nor used in the operation of the AI’s business. 12c. Multiple-name credit-linked notes / sold credit protection to basket of exposures This item refers to— (a) multiple-name CLNs (e.g. first-to-default CLNs) for which the applicable risk-weights are determined according to section 117(2) of the BCR; and (b) sold credit protection to a basket of reference obligations, where the protection is in the form of total return swap or credit default swap booked in the reporting AI’s banking book and the risk-weight applicable to the protection is determined according to section 117B(1), (2), (3) or (4) of the BCR. 12d. First loss portion of credit protection This item refers to the portion of an exposure that is below the materiality threshold mentioned in section 135(9) of the BCR. 12e. Other exposures not elsewhere reported whose risk-weight is 100% This item refers to investments or exposures that are risk-weighted at 100% and have not been reported in Classes I to XI, items 12a to 12c and Class XIII. 12f. Other exposures not elsewhere reported (a) This item refers to investments or exposures that have a risk-weight other than 100% and have not been reported in Classes I to XI, items 12c and 12d) and Class XIII. (b) If necessary, the MA may specify a risk-weight that is greater than 100% for an exposure falling within section 116 of the BCR. Such an exposure should be reported in this item. (c) This item also includes credit protection covered portions of exposures that are—

MA(BS)3(IIIa)/P.11 (03/2025)
 secured by recognized collateral for which the applicable risk￾weights are determined under Part 7 of the BCR; or  covered by recognized credit derivative contracts eligible for a risk-weight of 2% or 4% under section 134(6) of the BCR (the credit protection covered portions should be reported as a separate item from the credit protection covered portions mentioned in the first bullet and other exposures reported in this item). To avoid doubt, if the recognized credit derivative contracts concerned fall within section 226BI(b), 226I(b) or 226MC(b) of the BCR, the default risk exposures in respect of the contracts are regarded as zero for the purposes of Form MA(BS)3(IIIe).
26. Class XIII Collective Investment Scheme Exposures (CIS exposures)
Use of a single approach
(a) If a CIS exposure is risk-weighted only by using one approach, the exposure should be reported in— (i) any of items 13a(i) to 13a(vi) if either the look-through approach (LTA) or the third-party approach is used; (ii) any of items 13b(i) to 13b(vi) if the mandate-based approach (MBA) is used; or (iii) item 13c(i) if the fall-back approach (FBA) is used. (b) “Risk-weight” referred to in items 13a(i) to 13c(i) means the effective risk-weight applicable to a CIS exposure determined under Division 2 of Part 6B of the BCR. Use of a combination of approaches (c) If a CIS exposure to a collective investment scheme (CIS) is risk-weighted by using more than one approach, e.g. LTA for on-balance sheet assets held by the CIS and FBA for off-balance sheet exposures incurred by the CIS, the exposure should be reported in any of items 13d(i) to 13d(vi). (d) “Risk-weight” referred to in items 13d(i) to 13d(vi) is the effective risk-weight (RW) of a CIS exposure calculated as follows:
𝑅𝑊 =
∑𝑎 𝑅𝑊𝐴𝑎
𝑇𝐴 ∙ 𝐿 where—
(i) RWAa is the RWA of that portion of the underlying exposures of a CIS which is determined by using approach a; (ii) TA is the total assets of the CIS; and

MA(BS)3(IIIa)/P.12 (03/2025)
(iii) L is the leverage of the CIS calculated in accordance with section 226ZJ(2)(b) of the BCR. (See Part IIIa and IIIb – Annex B for numerical examples) B.3 Reporting of On-balance Sheet Exposures – Column A1 in Division A
27. If an on-balance sheet exposure is not covered by any recognized CRM, the whole
principal amount (after deduction of specific provisions 4 ) of the exposure should be reported in column A1 of the row for the exposure class and risk-weight applicable to the exposure.
28. If an on-balance sheet exposure is covered fully or partially by recognized CRM, the
exposure should be reported in column A1 in accordance with paragraphs 29 to 30 below.
29. CRM treatment by substitution of risk-weights (applicable to collateral, guarantees and
credit derivative contracts)
(a) The whole principal amount (after deduction of specific provisions) of the exposure should be divided into the credit protection covered portion(s) and the credit protection uncovered portion. (b) Each credit protection covered portion should be reported in column A1 of the row for the exposure class and risk-weight applicable to the credit protection concerned. That is, the credit protection covered portion should be allocated the risk-weight of the collateral, or, in the case of guarantee or credit derivative contract, the attributed risk-weight of the credit protection provider (or the risk-weight of 2% or 4% if the credit derivative contract falls within section 134(6) of the BCR). (c) The credit protection uncovered portion of the exposure, if any, should be reported in column A1 of the row for the exposure class and risk-weight applicable to the exposure. (d) In the case of⸺ (i) mortgage loans granted for the purchase of flats under the Home Ownership Scheme, Private Sector Participation Scheme, Tenants Purchase Scheme and other similar schemes which are covered by guarantees issued by Hong Kong Housing Authority; (ii) reverse mortgage loans granted under the Reverse Mortgage Programme of HKMC Insurance Limited; and (iii) mortgage loans granted under Mortgage Insurance Programme of HKMC Insurance Limited,

4 For the purposes of the BSC approach, “specific provisions”, as defined in section 105 of the BCR, includes partial write-offs.

MA(BS)3(IIIa)/P.13 (03/2025) the credit protection uncovered portion, if any, of the mortgage loans should be reported in column A1 under Class XA. The credit protection covered portion of the mortgage loans in relation to a guarantee provided by Hong Kong Housing Authority or an insurance provided by HKMC Insurance Limited should be reported in Class II and column A1 of item 2a if the guarantee or insurance concerned meets all the criteria set out in section 132 of the BCR.
30. CRM treatment by reduction of principal amount of exposures(applicable to on-balance
sheet netting)
The net credit exposure calculated under section 130 of the BCR should be reported in the exposure class to which the exposure belongs and in column A1 of the row for the risk-weight applicable to the exposure. B.4 Reporting of Off-balance Sheet Exposures other than Default Risk Exposures – Columns A2 and A3 in Division A
31. Off-balance sheet exposures (except default risk exposures and credit exposures arising
from unsegregated collateral posted)
(a) If an off-balance sheet exposure is not covered by any recognized CRM, the whole principal amount (net of specific provisions if applicable) of the exposure and its credit equivalent amount (CEA) should be reported respectively in column A2 and column A3 of the row for the exposure class and risk-weight applicable to the exposure. (b) If an off-balance sheet exposure is covered fully or partially by recognized CRM— (i) the whole principal amount (net of specific provisions if applicable) of the exposure should be reported in column A2 of the row for the exposure class and risk-weight applicable to the exposure; (ii) the amount reported in column A2 should be divided into the credit protection covered and uncovered portions and each of these portions should be multiplied by the credit conversion factor (CCF) applicable to the exposure; (iii) the CEA of each credit protection covered portion should be reported in column A3 of the row for the exposure class and risk-weight applicable to the credit protection concerned; and (iv) the CEA of the credit protection uncovered portion should be reported in column A3 of the row for the exposure class and risk-weight applicable to the exposure.
32. Off-balance sheet exposures arising from unsegregated collateral posted by reporting
AI
In the case of off-balance sheet exposures to which section 118(2) of the BCR applies, the reporting AI should report the whole principal amount (net of specific provisions if applicable) of the collateral in columns A2 and A3 of the row for the exposure class and risk-weight applicable to the person holding the collateral.

MA(BS)3(IIIa)/P.14 (03/2025)
B.5 Reporting of Off-balance Sheet Exposures that are Default Risk Exposures – Columns A2 and A4 in Division A
33. For any derivative contracts or SFTs entered into by the reporting AI with a
counterparty, the AI should report the amounts listed below in column A2 of the row for the exposure class and risk-weight applicable to the default risk exposures to the counterparty:
(a) in the case of derivative contracts—the gross sum of the stated notional amounts of the derivative contracts entered into with the counterparty; (b) in the case of SFTs— (i) the principal amounts of any securities sold or lent to the counterparty by the AI under the SFTs; (ii) the principal amounts of any money paid or lent to the counterparty by the AI under the SFTs; and (iii) the principal amounts of any securities or money provided to the counterparty as collateral by the AI under the SFTs.
34. For any default risk exposure that is calculated by using the SA-CCR approach or the
IMM(CCR) approach⸺
(a) if the exposure is not covered by any recognized CRM 5 , the outstanding default risk exposure of the netting set (or the default risk exposure if the netting set contains SFTs only), net of specific provisions if applicable, should be reported in column A4 of the row for the exposure class and risk-weight applicable to the exposure; (b) if— (i) the exposure is covered fully or partially by recognized collateral and falls within section 126(1A)(c) of the BCR; (ii) the exposure is covered fully or partially by a recognized guarantee or recognized credit derivative contract; or (iii) the exposure falls within both subparagraphs (i) and (ii), the reporting arrangement for column A4 is as follows:

5
In the case of SFTs, “recognized CRM” refers to recognized guarantees and recognized credit derivative contracts as securities or money received by the AI under the SFTs have already been taken into account in the calculations under the IMM(CCR) approach, they should not be taken into account again under Part 5. In the case of derivative contracts, “recognized CRM” refers to recognized collateral whose credit risk mitigation effect can be taken into account under section 126(1A)(c) of the BCR, recognized guarantees and recognized credit derivative contracts.

MA(BS)3(IIIa)/P.15 (03/2025)
(iv) the outstanding default risk exposure or default risk exposure, as the case may be, net of specific provisions if applicable, should be divided into the credit protection covered and uncovered portions; (v) each credit protection covered portion should be reported in column A4 of the row for the exposure class and risk-weight applicable to the credit protection concerned; and (vi) the credit protection uncovered portion should be reported in column A4 of the row for the exposure class and risk-weight applicable to the exposure.
35. For any default risk exposure that is calculated by using the current exposure method⸺
(a) if the exposure is not covered by any recognized CRM, the outstanding default risk exposure of the derivative contract concerned, net of specific provisions if applicable, should be reported in column A4 of the row for the exposure class and risk-weight applicable to the exposure; (b) if the exposure is covered fully or partially by one or more than one type of recognized CRM, the outstanding default risk exposure of the derivative contract concerned should be reported in column A4 in the same manner as set out in paragraph 34(b)(iv) to (vi).
36. Any default risk exposure that is calculated for an SFT in accordance with section
226MJ of the BCR and covered fully or partially by one or more than one type of recognized CRM should be reported in column A4 in the same manner as set out in paragraph 34(b)(iv) to (vi).
37. If the reporting AI issues a CLN to cover a default risk exposure, the amount of the
proceeds received from the issuance of the CLN should not be included in the calculation of the amount of the default risk exposure under Division 1A, 2, 2A or 2B of Part 6A of the BCR. The AI may only take into account the CRM effect of the proceeds in the calculation of the RWA of the default risk exposure in accordance with
section 135(8) of the BCR.
B.6 Reporting of Risk-weighted Amount – Column A6 in Division A
38. For all items in Division A, the RWA reported in column A6 is calculated by
multiplying the sum of the amounts reported in columns A1, A3 and A4 by the risk￾weight in column A5.
Section C: Reporting arrangements for Division B of Part IIIa
C.1 General Instructions
39. Unless otherwise stated in these completion instructions, the reporting AI is not required
to report in Parts II, III, IV and V of Division B any derivative contract or SFT that is outside the scope of Divisions 1A, 2, 2A and 2B of Part 6A of the BCR (please refer to the “Q&As on exposures to counterparty credit risk and central counterparties” for more information). Default risk exposures reported in columns B12, B21, B27 and B36

MA(BS)3(IIIa)/P.16 (03/2025) should not be reduced by any CVA loss or specific provisions made. Outstanding default risk exposures in respect of derivative contracts and any specific provisions made for default risk exposures should be reported in Column A4 in Division A of this Form.
40. Breakdown of CEAs and default risk exposures by exposure class in Division B should
be consistent with the exposure classes into which the off-balance sheet exposures concerned are classified for the purposes of Division A. C.2 Part I of Division B - Off-balance Sheet Exposures other than Default Risk Exposures
41. The reporting AI should classify each of its off-balance sheet exposures other than
default risk exposures into the appropriate standard items listed in paragraph 42 and report the exposures in Part I of Division B of this Form.
42. CCFs for items 1 to 11 are set out in Schedule 6 to the BCR.
Item no. Nature of item

1. Direct credit substitutes
2. Transaction-related contingencies
3. Trade-related contingencies
4. Asset sales with recourse
5. Sale and repurchase agreements (excluding repo-style transactions)
6. Forward asset purchases
   This item also captures off-balance sheet exposures arising from the reporting AI’s commitments to subscribe to CISs’ future capital calls. To avoid doubt, forward start repo-style transactions should be reported in item 10b or c instead of this item.
7. Partly paid-up shares and securities
8. Forward forward deposits placed
   This refers to a commitment of the reporting AI to place a forward forward deposit. If the reporting AI has contracted to receive a forward forward deposit, failure to deliver by the counterparty will result in an unanticipated change in the AI’s interest rate exposure and may involve a replacement cost. Such exposure should therefore be regarded as default risk

MA(BS)3(IIIa)/P.17 (03/2025) exposures arising from interest rate contracts and reported in Part II, III or V of Division B, as the case requires.
9. Note issuance and revolving underwriting facilities
10a. to c. Other commitments
Included is the undrawn portion of any arrangement that falls within the definition of “commitment” defined in section 2 of Schedule 6 to the BCR and does not fall within any of items 1 to 9. A commitment is regarded as being created no later than the acceptance in writing by the customer of the facility offered. In the case of an off-balance sheet exposure (exposure A) arising from a commitment the drawdown of which will give rise to another off-balance sheet exposure (exposure B) falling within any of items 1 to 9 and 11, the CCF applicable to exposure A should be the lower of— (a) the CCF applicable to exposure A according to Schedule 6 to the BCR; and (b) the CCF applicable to exposure B according to that Schedule. 10a. Exempt commitments 10b. Other commitments (CCF at 10%) This item captures commitments (other than exempt commitments) that— (a) may be cancelled at any time unconditionally by the reporting AI concerned without prior notice; or (b) provide for automatic cancellation due to deterioration in the creditworthiness of the persons to whom the reporting AI has made the commitments. 10c. Other commitments (CCF at 40%) This item captures commitments that do not fall within items 10a and 10b. 11a. to d. Off-balance sheet exposures not specified above 11a. This item captures off-balance sheet exposures that do not fall within items 1 to 10c and that are subject to a CCF of 100%. Such exposures include, but not limited to⸺ (a) off-balance sheet exposures to the credit risk of the underlying assets of cash-settled derivative contracts (e.g. equity forward contracts) booked in the reporting AI’s banking book; and

MA(BS)3(IIIa)/P.18 (03/2025)
(b) credit exposures to persons holding unsegregated collateral posted by the reporting AI (other than collateral posted that is included in the default risk exposures reported in Part II, III, IV or V of Division B of this Form and Form MA(BS)3(IIIe)) (see section 118(2) of the BCR). 11b. to d. These items capture off-balance sheet exposures that do not fall within items 1 to 10c and that are subject to a CCF specified in Part 2 of Schedule 1 to the BCR. For other off-balance sheet exposures not mentioned above, the reporting AI should consult the HKMA on the reporting arrangements.
43. The reporting AI should report each of its off-balance sheet exposures as follows:
(a) report in column B2 the principal amount (net of specific provisions if applicable) of the exposure; (b) report in column B3 the CEA of the exposure (i.e. the product of the amount reported in column B2 and the applicable CCF specified in column B1); and (c) report the CEA of the exposure in one of columns B4 to B10 6 if the exposure falls within any one of the following exposure classes⸺ (i) Class I Sovereign Exposures; (ii) Class II Public Sector Entity (PSE) Exposures; (iii) Class III Multilateral Development Bank (MDB) Exposures 7 ; (iv) Class IV Unspecified Multilateral Body Exposures 7 ; (v) Class V Bank Exposures; (vi) Class XA Regulatory Residential Real Estate Exposures 8 ; (vii) Class XB Other Real Estate Exposures 8 ; (viii) Class XII Other Exposures; and (ix) Class XIII Collective Investment Scheme Exposures (CIS exposures).

6 Only breakdown by major exposure classes is required. As a result, for each row, the total amount reported in column B3 would be greater than or equal to the sum of the total amounts reported in columns B4 to B10. 7 To be reported in column B6. 8 To be reported in column B8.

MA(BS)3(IIIa)/P.19 (03/2025)
C.3 Part II of Division B - Default Risk Exposures in respect of Derivative Contracts 9 (Current Exposure Method)
44. If the reporting AI uses the current exposure method to calculate default risk exposures,
itshould report the exposuresso calculated in the appropriate items in Part II of Division B. Item no. Nature of item
12. Interest rate contracts
13. Exchange rate contracts
14. Credit-related derivative contracts
15. Equity-related derivative contracts
16. Commodity-related derivative contracts
17. Other derivative contracts not specified above
18. Of which: Offsetting or CCP-related transactions with clearing
members or clearing clients
This item is for reporting the amounts captured under items 12 to 17 that are related to offsetting transactions or CCP-related transactions entered into by the reporting AI with clearing members or clearing clients (see Part IIIe – Annex A and paragraph 5 of the completion instructions for Form MA(BS)3(IIIe) for more information on exposures related to centrally cleared transactions that should be reported in this Form).
45. The reporting AI should report each of its derivative contracts entered into with a
counterparty as follows:
(a) report in column B11 the stated notional amount of the derivative contract; (b) report in column B12 the default risk exposure of the derivative contract calculated under the current exposure method; and (c) report the default risk exposure of the derivative contract in one of columns B13 to B17 10 if the counterparty to the contract is a sovereign, PSE, MDB, unspecified multilateral body, bank, corporate or individual.

9 Derivative contracts include long settlement transactions that fall within paragraph (c) or (d) of the definition of “derivative contract” in section 2(1) of the BCR. For example, a long settlement transaction that is a FX spot transaction must be reported as an exchange rate contract. 10 Only breakdown by major exposure classes is required. As a result, for each row, the total amount reported in column B12 would be greater than or equal to the sum of the total amounts reported in columns B13 to B17.

MA(BS)3(IIIa)/P.20 (03/2025)
46. The total of all stated notional amounts reported in column B11 of each of items 12 to
18 should be the gross sum of the stated notional amounts.
47. To avoid doubt, sold options falling within section 226MB(2) of the BCR should also
be reported. However, the reporting AI is not required to report credit derivative contracts falling within section 226MC of the BCR in Part II of Division B 11 . C.4 Part III of Division B - Default Risk Exposures in respect of Derivative Contracts 12 (SA-CCR approach)
48. If the reporting AI uses the SA-CCR approach to calculate default risk exposures, it
should report the exposures so calculated in the appropriate items in Part III of Division B (See Part IIIa and IIIb – Annex A for numerical examples). Item no. Nature of item
19. Unmargined contracts not covered by recognized netting
This item captures derivative contracts—
(a) that fall within the definition of unmargined contract in section 226BA of the BCR; and (b) that are not covered by recognized netting. The following contracts should also be reported in this item— (a) contracts that fall within section 226BH(2) or (4) of the BCR; and (b) contracts that have been removed from the netting sets concerned under section 226BH(3)(b) or (5) of the BCR.
20. Margined contracts not covered by recognized netting
This item captures derivative contracts—
(a) that fall within the definition of margined contract in section 226BA of the BCR; and (b) that are not covered by recognized netting.
21. Contracts covered by recognized netting
This item captures derivative contracts (whether they are margined contracts or not) covered by recognized netting.

11 This is to avoid double counting as the notional amounts of the contracts concerned are somehow reflected in the amounts reported in Division A (e.g. credit protection covered portions) or Part I of Division B (e.g. direct credit substitutes). 12 See footnote 9.

MA(BS)3(IIIa)/P.21 (03/2025)
22. Out of the amounts reported in items 19, 20 and 21, the amounts for
offsetting or CCP-related transactions with clearing members or clearing clients This item is for reporting the amounts captured under items 19 to 21 that are related to offsetting transactions or CCP-related transactions entered into by the reporting AI with clearing members or clearing clients (see
Part IIIe – Annex A and paragraph 5 of the completion instructions for
Form MA(BS)3(IIIe) for more information on exposures related to centrally cleared transactions that should be reported in this Form).
49. For all items in Part III of Division B—
(a) if a netting set contains a credit derivative contract that falls within section 226BI of the BCR and the reporting AI has— (i) treated the default risk exposure of such credit derivative contract as zero; and (ii) removed such credit derivative contract from the netting set (i.e. the default risk exposure of the netting set is calculated as if the credit derivative contract did not exist), the reporting AI is not required to report such credit derivative contract in Part III of Division B 13; (b) the amount reported in column B18 is the gross sum of the stated notional amounts of the relevant derivative contracts.
50. For item 19—
(a) report in column B19 the replacement cost of a derivative contract calculated in accordance with Division 1A of Part 6A of the BCR by using the formula applicable to the contract. In the case of a sold option whose default risk exposure is set to zero under 226BH(2) or (3) of the BCR, the replacement cost of the option may be reported as zero; (b) report in column B20 the potential future exposure of the derivative contract calculated in accordance with Division 1A of Part 6A of the BCR by using the formulas applicable to the asset class into which the contract falls. In the case of a sold option whose default risk exposure is set to zero under section 226BH(2) or (3) of the BCR, the potential future exposure of the option may be reported as zero; (c) report in column B21 the default risk exposure of the derivative contract (i.e. the sum of the amounts reported in columns B19 and B20 multiplied by 1.4); and

13 See footnote 11.

MA(BS)3(IIIa)/P.22 (03/2025)
(d) report the default risk exposure of the derivative contract in one of columns B22 to B26 14 if the counterparty to the contract is a sovereign, PSE, MDB, unspecified multilateral body, bank, corporate or individual.
51. The reporting arrangements mentioned in paragraph 50 also apply to item 20. Also—
(a) if the default risk exposure calculated for a margined contract on an unmargined basis is regarded as the default risk exposure of the contract, the default risk exposure calculated on an unmargined basis should be reported in column B21 (see
section 226BH(1) of the BCR);
(b) if more than one derivative contract is covered by a single variation margin agreement— (i) the stated notional amount of each of the derivative contracts should be reported in column B18 of item 20a, 20b, 20c, 20d or 20e, as the case requires; (ii) there is no need to report the replacement cost, potential future exposure and default risk exposure calculated for these contracts by type of contract. The amounts calculated under sections 226BE(3), 226BS and 226BE(2) of the BCR should be reported in columns B19, B20 and B21 of item 20f respectively.
52. For item 21, the replacement cost, potential future exposure and default risk exposure
of a netting set or a group of netting sets, as the case may be, should be reported in the row “SUBTOTAL” of columns B19, B20 and B21 respectively. The reporting arrangements mentioned in paragraphs 50(c) and 50(d) and paragraph 51(a) apply to the netting set or the group of netting sets as they apply to a single derivative contract. C.5 Part IV of Division B - Default Risk Exposures in respect of SFTs (Non-IMM(CCR) Approach)
53. If the reporting AI calculates default risk exposures in respect of SFTs under Division
2B of Part 6A of the BCR, it should report the exposures so calculated in the appropriate items in Part IV of Division B as follows:
(a) Under item 23a, for each of the SFTs entered into by the reporting AI— (i) report in column B27 the default risk exposure of the SFT calculated under
section 226MJ of the BCR; and
(ii) report the default risk exposure in one of columns B28 to B32 15 if the counterparty to the SFT is a sovereign, PSE, MDB, unspecified multilateral body, bank, corporate or individual. (b) Item 23b is for reporting the amounts captured under item 23a that are related to offsetting transactions or CCP-related transactions entered into by the reporting AI with clearing members or clearing clients (see Part IIIe – Annex A and paragraph

14 Only breakdown by major exposure classes is required. As a result, for each row, the total amount reported in column B21 would be greater than or equal to the sum of the total amounts reported in columns B22 to B26. 15 Only breakdown by major exposure classes is required. As a result, for each row, the total amount reported in column B27 would be greater than or equal to the sum of the total amounts reported in columns B28 to B32.

MA(BS)3(IIIa)/P.23 (03/2025)
5 of the completion instructions for Form MA(BS)3(IIIe) for more information on exposures related to centrally cleared transactions that should be reported in this Form). C.6 Part V of Division B - Default Risk Exposures (IMM(CCR) Approach)
54. If the reporting AI uses the IMM(CCR) approach to calculate default risk exposures, it
should report the exposures so calculated in the appropriate items in Part V of Division B. Item no. Nature of item
24. Portfolio-level risk-weighted amount based on current market data
The portfolio-level RWA calculated under section 226D(1)(a) and (2)(a) of the BCR should be reported in this item.
25. Portfolio-level risk-weighted amount based on stress calibration
The portfolio-level RWA calculated under section 226D(1)(b) and (2)(b) of the BCR should be reported in this item. Only the higher of item 24 and item 25 will be used in the calculation of the total RWA for credit risk under the BSC approach.
26. to 29. Items 26 to 29 capture the breakdown of the default risk exposures
included in the portfolio-level RWA that will be used in the capital adequacy ratio calculation. In other words, if the portfolio-level RWA calculated using current market data is larger, the default risk exposures reported in items 26 to 29 should be those used in calculating the RWA reported in item 24.
26. Netting sets (not subject to recognized netting)
This item captures transactions—
(a) that are not subject to recognized netting; or (b) that are required to be treated as a separate netting set under section 226J(1) of the BCR. If the reporting AI’s IMM(CCR) approval covers one or more than one of the following categories of transactions:
(a) derivative contracts (excluding long settlement transactions (LSTs)); (b) SFTs (excluding LSTs); and (c) LSTs, the AI should report each of its transactions in item 26a, 26b or 26c based on the category within which the transaction falls.

MA(BS)3(IIIa)/P.24 (03/2025)
27. Netting sets (subject to valid bilateral netting agreements)
This item captures transactions—
(a) that are subject to valid bilateral netting agreements; and (b) that are not required to be treated as a separate netting set under
section 226J(1) of the BCR.
Derivative contracts and SFTs covered by the reporting AI’s IMM(CCR) approval must be reported in items 27a and 27b respectively. The amounts reported in these two items will include derivative contracts and SFTs that are LSTs unless these LSTs are not covered by the IMM(CCR) approval. If the reporting AI’s IMM(CCR) approval only covers LSTs, the AI should report the LSTs in item 27c.
28. Netting sets (subject to valid cross-product netting agreements)
This item captures transactions—
(a) that are subject to valid cross-product netting agreements; and (b) that are not required to be treated as a separate netting set under
section 226J(1) of the BCR.
LSTs are included unless the IMM(CCR) approval of the reporting AI does not cover LSTs.
29. Out of the amounts reported in items 26, 27 and 28, the amounts for
offsetting or CCP-related transactions with clearing members or clearing clients This item is for reporting the amounts captured under items 26 to 28 that are related to offsetting transactions or CCP-related transactions entered into by the reporting AI with clearing members or clearing clients (see
Part IIIe – Annex A and paragraph 5 of the completion instructions for
Form MA(BS)3(IIIe) for more information on exposures related to centrally cleared transactions that should be reported in this Form).
55. The reporting AI should report the default risk exposures calculated under the
IMM(CCR) approach in Part V of Division B of this Form as follows:
(a) report in column B34 of items 26a, 26c, 27a, 27c, 28a and 29a the gross sum of the stated notional amounts of the derivative contracts and LSTs concerned; (b) report in column B35 of items 26b, 26c, 27b, 27c, 28b, 28c and 29a the principal amounts of the securities sold, lent or delivered, or the money paid, by the AI to the counterparties under the SFTs and LSTs concerned;

MA(BS)3(IIIa)/P.25 (03/2025)
(c) report in column B36 of items 26a to 27c, 28 and 29a the default risk exposures of the netting sets concerned calculated under section 226E of the BCR. In the case of item 26, the netting set only contains one transaction; and (d) report the default risk exposure of each of the netting sets reported in column B36 in one of columns B37 to B41 16 if the counterparty to the netting set is a sovereign, PSE, MDB, unspecified multilateral body, bank, corporate or individual.
56. If a netting set contains a credit derivative contract that falls within section 226I of the
BCR and the reporting AI has—
(a) treated the default risk exposure of such credit derivative contract as zero; and (b) removed such credit derivative contract from the netting set (i.e. the default risk exposure of the netting set is calculated as if the credit derivative contract did not exist), the reporting AI is not required to report such credit derivative contract in Part V of Division B of this Form 17 . C.7 Multiple Credit Risk Mitigation
57. If an exposure is covered by two or more forms of recognized CRM (e.g. with both
collateral and guarantee partially covering the exposure), the treatments for the recognized CRM are set out in section 136(1) and (2) of the BCR. The calculation of the RWA of each portion will be done separately.
58. Unless otherwise stated in the BCR (e.g. section 126(1C)), the reporting AI may
determine, at its discretion, how recognized CRM that is shared by two or more on￾balance sheet and/or off-balance sheet exposures are allocated to each of the exposures for the purpose of RWA calculation, as long as the AI’s allocation is not inconsistent with the terms and conditions of the relevant legal documentation. C.8 Maturity Mismatches
59. If the credit protection provided has a residual maturity which is shorter than the
residual maturity of the exposure, the reporting AI must not take into account the CRM effect of that credit protection. Hong Kong Monetary Authority March 2025

16 Only breakdown by major exposure classes is required. As a result, for each row, the total amount reported in column B36 would be greater than or equal to the sum of the total amounts reported in columns B37 to B41. 17 See footnote 11.

MA(BS)3(IIIb)/P.1 (03/2025)
Completion Instructions
Return of Capital Adequacy Ratio
Part IIIb – Risk-weighted Amount for Credit Risk
Standardized (Credit Risk) Approach
Form MA(BS)3(IIIb)
Introduction

1. Form MA(BS)3(IIIb) of Part III should be completed by each authorized institution (AI)
   incorporated in Hong Kong using the standardized (credit risk) approach (STC approach) to calculate credit risk under Part 4 of the Banking (Capital) Rules (BCR).
2. This Form covers the following exposures of a reporting AI:
   (a) all on-balance sheet exposures and off-balance sheet exposures booked in its banking book; (b) all default risk exposures to counterparties under securities financing transactions (SFTs) and derivative contracts booked in its trading book; (c) all credit exposures to counterparties in respect of transactions (other than repo-style transactions) in securities, foreign exchange or commodities booked in its trading book that remain outstanding after the settlement dates in respect of the transactions; (d) all credit exposures to counterparties in respect of unsegregated collateral posted by the AI and held by the counterparties for transactions or contracts booked in AI’s trading book; and (e) if applicable, the AI’s market risk exposures that are exempted from section 17 under
   section 22 of the BCR, except for its total net open position in foreign exchange
   exposures as derived in accordance with section 296 of the BCR.
3. This Form does not cover the following exposures:
   (a) portions of exposures (which may be all of the exposures) that are required to be deducted from any of the AI’s CET1 capital, Additional Tier 1 capital and Tier 2 capital under Division 4 of Part 3 of the BCR (which should be reported in Form MA(BS)3(II)); (b) securitization exposures (which should be reported in Form MA(BS)3(IIId)); (c) the underlying exposures of eligible traditional securitization transactions if the AI opts to apply the treatment under section 230(1) of the BCR to the underlying exposures; (d) default fund contributions made to qualifying CCPs and non-qualifying CCPs (which should be reported in Form MA(BS)3(IIIe));

MA(BS)3(IIIb)/P.2 (03/2025)
(e) default risk exposures to qualifying CCPs (which should be reported in Form MA(BS)3(IIIe)); and (f) exposures that are risk-weighted as if they were default risk exposures to qualifying CCPs under Division 4 of Part 6A (which should be reported in Form MA(BS)3(IIIe)).
4. This Form and these completion instructions should be read in conjunction with the BCR
and the relevant supervisory policy/guidance related to the capital adequacy framework.
Section A: Definitions and Clarification
5. In these instructions—
(a) “gross sum of the stated notional amounts” refers to the sum of the stated notional amounts of all relevant contracts, without the stated notional amounts of contracts with positive replacement costs being reduced by the stated notional amounts of contracts with negative or zero replacement costs, regardless of whether the contracts are subject to recognized netting. (b) “recognized CRM” refers to recognized collateral, recognized netting, recognized guarantees and recognized credit derivative contracts. To avoid doubt, guarantees issued by other offices of the reporting AI are not regarded as recognized credit risk mitigation. Debt securities which are re-securitization exposures (whether rated or not) cannot be recognized as collateral (see sections 79(2) and 80(2) of the BCR). (c) “stated notional amount” means the nominal notional amount of a derivative contract. It should not be confused with any effective notional amount or adjusted notional calculated for the derivative contract under Part 6A of the BCR.
6. Double counting of exposures arising from the same contract or transaction should be
avoided. For example, only the undrawn portion of a loan commitment should be reported as an off-balance sheet exposure while the actual amount which has been lent out should be reported as an on-balance sheet exposure. Trade-related contingencies, such as trust receipts and shipping guarantees, which have already been reported as letters of credit issued or loans against import bills etc. should not be counted again as off￾balance sheet exposures.
7. In certain cases, exposures to counterparties arising from derivative contracts entered into
by the reporting AI with those counterparties may already be reflected, in part, on the reporting AI’s balance sheet. For example, the AI may have recorded the fair value of a derivative contract on its balance sheet. To avoid double counting, such amount should be excluded from on-balance sheet exposures and treated as off-balance sheet exposures for the purposes of this Form.
8. Accruals on an exposure should be classified and risk-weighted in the same way as the
exposure. Accruals which cannot be so classified should, with the prior consent of the Monetary Authority (MA), be included in Class XV (Other Exposures which are not Defaulted Exposures).
9. For specified SFTs booked in the reporting AI’s banking book⸺

MA(BS)3(IIIb)/P.3 (03/2025)
(a) if the assets underlying the SFTs are non-securitization exposures, the AI’s credit exposures to the assets underlying the SFTs should be reported in Division A of this Form (see also section 68C(2) of the BCR); (b) if the assets underlying the SFTs are securitization exposures, the AI’s credit exposures to the assets underlying the SFTs should be risk-weighted in accordance with Part 7 of the BCR and reported in Form MA(BS)3(IIId) (see also section 68C(3) of the BCR).
10. For specified SFTs booked in the reporting AI’s trading book, the AI’s exposures to the
assets underlying the SFTs are market risk exposures. Hence, the AI only needs to calculate the risk-weighted amounts (RWAs) of its market risk exposures to the assets in accordance with Part 8 of the BCR (see section 68C(4) of the BCR) and reports the exposures in the corresponding Return Form for market risk. The AI is not required to calculate any RWA for the credit risk of the assets. However, if the AI is granted an exemption under section 22 of the BCR, the AI should comply with section 68C(2) instead of section 68C(4) of the BCR in calculating the RWAs of its exposures to the assets, and report the exposures in this Form instead.
11. An originating institution of a non-eligible securitization transaction must report the
RWA of the underlying exposures of the transaction in this Form as if the exposures were not securitized. If the credit risk mitigation (CRM) afforded to the underlying exposures of an eligible synthetic securitization transaction is not in the form of tranched credit protection, the underlying exposures must be reported in this Form in the same manner as a non-eligible securitization transaction except that the CRM for transferring the credit risk of the underlying exposures to the other parties to the transaction can be taken into account in the RWA calculation and therefore should also be included in the reporting. However, if the CRM is in the form of tranched credit protection, both the underlying exposures and the CRM effect must be reported in Form MA(BS)3(IIId) (please see paragraph 15(b) of the completion instructions for Form MA(BS)3(IIId)). For cases which are not specified in these instructions or in any other supervisory guidance relevant to securitization transactions, reporting AIs should consult the HKMA on the reporting arrangements.
Section B: Reporting arrangements for Division A of Part IIIb
B.1 Exposure Classification
12. Division A of this Form is organized according to the following standard exposure classes
into which on-balance sheet and off-balance sheet exposures should be classified under the STC approach:
Class I Sovereign Exposures
Class II Public Sector Entity Exposures
Class III Multilateral Development Bank (MDB) Exposures Class IV Unspecified Multilateral Body Exposures Class V Bank Exposures Class VI Eligible Covered Bond Exposures

MA(BS)3(IIIb)/P.4 (03/2025)
Class VII Qualifying Non-bank Financial Institution (QNBFI) Exposures Class VIII Corporate Exposures Class IX Retail Exposures Class X IPO Financing Class XIA Regulatory Residential Real Estate Exposures Class XIB Regulatory Commercial Real Estate (CRE) Exposures Class XIC Real Estate Exposures other than Regulatory Real Estate Exposures Class XID Land Acquisition, Development and Construction Exposures Class XIIA Equity Exposures Class XIIB Significant Capital Investments in Commercial Entities Class XIIC Insignificant and Significant LAC Investments Class XIID Subordinated Debts Class XIII Cash and Gold Class XIV Exposures to Items in the Process of Clearing or Settlement Class XV Other Exposures which are not Defaulted Exposures Class XVI Defaulted Exposures Class XVII Collective Investment Scheme Exposures (CIS exposures)
13. The exposure classes are mutually exclusive and therefore each exposure should be
reported under only one of them. However, it should be noted that a single transaction may give rise to more than one exposure. For example, a derivative contract booked in the banking book has an exposure to the counterparty to the derivative contract and may also have a credit exposure to the asset underlying the derivative contract.
14. Classification of credit-linked notes (CLNs) held
(a) A single-name CLN that has an ECAI issue specific rating should be reported in Division A under— (i) the exposure class applicable to the issuer of the CLN if the CLN is allocated the risk-weight determined in accordance with section 68(1)(b) of the BCR; or (ii) the exposure class applicable to the reference obligation of the CLN if the CLN is allocated the risk-weight attributable to the reference obligation determined in accordance with section 68(1)(c) of the BCR. If no scale of credit quality grades is applicable to the ECAI issue specific rating of the CLN (e.g. the rating is issued by a Type B ECAI but the use of the ECAI ratings issued by such Type B ECAI to risk-weight the CLN is prohibited by a restriction published by the MA under section 4B(3) of the BCR), the AI should classify the CLN into an exposure class in accordance with paragraph (b). (b) A single-name CLN without an ECAI issue specific rating should be reported in Division A under—

MA(BS)3(IIIb)/P.5 (03/2025)
(i) the exposure class applicable to the issuer of the CLN if the CLN is allocated the risk-weight determined in accordance with section 68(2)(a) of the BCR; or (ii) the exposure class applicable to the reference obligation of the CLN if the CLN is allocated the risk-weight attributable to the reference obligation determined in accordance with section 68(2)(b) of the BCR. (c) A multiple-name CLN (e.g. a first-to-default CLN) should be reported in Class XV item 15b regardless of whether the CLN has an ECAI issue specific rating or not.
15. Classification of off-balance sheet exposures
Off-balance sheet exposures must be classified into exposure classes in the same manner as on-balance sheet exposures (i.e. based on the source of credit risk). In particular— (a) in the case of an asset sale with recourse, a sale and repurchase agreement (other than a repo-style transaction) or a forward asset purchase, since the credit risk is arising from the asset that could be repurchased or is to be purchased in the future, the exposure should be classified into the exposure class within which the asset sold/to be purchased (e.g. equities) would fall if the asset were held by the reporting AI; (b) in the case of partly paid-up shares and securities, since the credit risk associated with the shares or securities is in effect passed to the reporting AI, the exposure should be classified into the exposure class within which the relevant shares or securities would fall if they were on-balance sheet exposures of the reporting AI; (c) in the case of a direct credit substitute arising from the selling of credit protection in the form of total return swap or credit default swap booked in the reporting AI’s banking book, the exposure should be classified into the exposure class within which the relevant reference obligation of the swap would fall if the reference obligation were an on-balance sheet exposure of the reporting AI. If the swap provides credit protection to a basket of reference obligations, the exposure should be classified into Class XV; and (d) in the case of default risk exposures, the exposures should be classified into the exposure classes within which the counterparties to the derivative contracts or SFTs concerned fall. B.2 Specific Instructions related to the Use of ECAI Ratings
16. The latest list of external credit assessment institutions (ECAIs) and the mapping tables
of these ECAIs’ ratings with credit quality grades are published on the HKMA’s website.
17. The use of ECAI ratings assigned by Type B ECAIs are subject to one or more than one
restriction published by the MA under section 4B(3) of the BCR. AIs should refer to the HKMA’s website for the restriction(s) imposed on each Type B ECAI.
18. If an exposure does not have any ECAI issue specific rating, but the obligor of the
exposure has at least one ECAI issuer rating and/or any of its other debt obligations has

MA(BS)3(IIIb)/P.6 (03/2025) at least one long-term ECAI issue specific rating, the reporting AI should apply section 54E to determine which of these ECAI ratings must be used for the purpose of determining the risk-weight applicable to the exposure. B.3 Specific Instructions for Selected Exposure Classes
19. Class I Sovereign Exposures
Item 1a - domestic currency exposures to the Government (a) Only exposures to the Government, such as deposits placed with, and loans made to, the Government (including those for the account of the Exchange Fund and the clearing balances with the Exchange Fund), that are denominated and funded in Hong Kong dollars can be reported in item 1a(i). Foreign currency exposures to the Government should be reported in item 1b. (b) The credit protection covered portion of a repo-style transaction secured by debt securities denominated in Hong Kong dollars issued by the Government should be reported in item 1a(iii) if the reporting AI uses the simple approach to take into account the CRM effect of the debt securities and any one or more of the conditions set out in section 82(4) of the BCR are not met. (c) Market makers who have short positions in Exchange Fund Bills/Notes may report their net holdings of such instruments provided that the short positions are covered by the Sale and Repurchase Agreements with the HKMA.

(ii) The reporting AI should report the credit protection covered portion of the exposures in— (A) item 13f—  if the exposures are default risk exposures arising from repo-style transactions that do not fall within section 82(3) of the BCR; or  if the exposures are not default risk exposures and there is currency mismatch between the cash collateral and the exposures (i.e. section 82(5) of the BCR does not apply); (B) item 13g if the exposures are default risk exposures arising from repo￾style transactions that fall within section 82(3)(b) of the BCR; or (C) item 13h—  if the exposures are default risk exposures arising from repo-style transactions that fall within section 82(3)(a) of the BCR; or  if the exposures are not default risk exposures and there is no currency mismatch between the cash collateral and the exposures (i.e. section 82(5) of the BCR applies).

MA(BS)3(IIIb)/P.11 (03/2025)
(iii) However, when the cash collateral is held at a third-party bank in a non-custodial arrangement and unconditionally and irrevocably pledged or assigned to the reporting AI, the credit protection covered portion concerned must be reported as an exposure to that third-party bank under Class V and therefore must not be reported in items 13f to 13h.

(b) Item 14d captures any transaction in securities (other than repo-style transaction), or any transaction in foreign exchange or commodities, that is entered into on a delivery-versus-payment (DvP) basis 2 where payment / delivery has not yet taken place after the settlement date. (c) Item 14e captures any transaction in securities (other than repo-style transaction), or any transaction in foreign exchange or commodities, that is entered into on a non￾DvP basis where payment / delivery from the counterparty concerned has not yet taken place after the settlement date. The amount of the payment made or the current market value of the thing delivered by the reporting AI, plus any positive current exposure associated with the transaction, should be reported as an exposure in item 14e(i) or (ii), as the case requires. The amount reported in item 14e(i) should be risk￾weighted as an exposure to the counterparty to the transaction.
34. Class XV Other Exposures which are not Defaulted Exposures

To avoid doubt, if the recognized credit derivative contracts concerned fall within section 226BI(b) or 226I(b) of the BCR, the default risk exposures in respect of the contracts are regarded as zero for the purposes of Form MA(BS)3(IIIe).
35. Class XVI Defaulted Exposures
Included in this exposure class are defaulted exposures and their credit protection covered portions (if any). In other words, the credit protection covered portions of defaulted exposures should not be reported in the exposure class applicable to the credit protection (see also paragraphs 37, 39 and 40).

MA(BS)3(IIIb)/P.14 (03/2025)
Use of a combination of approaches
(c) If a CIS exposure to a collective investment scheme (CIS) is risk-weighted by using more than one approach, e.g. LTA for on-balance sheet assets held by the CIS and FBA for off-balance sheet exposures incurred by the CIS, the exposure should be reported in any of items 17d(i) to 17d(vi). (d) “Risk-weight” referred to in items 17d(i) to 17d(vi) is the effective risk-weight (RW) of a CIS exposure calculated as follows:
𝑅𝑊 =
∑𝑎 𝑅𝑊𝐴𝑎
𝑇𝐴 ∙ 𝐿 where—
(i) RWAa is the RWA of that portion of the underlying exposures of a CIS which is determined by using approach a; (ii) TA is the total assets of the CIS; and (iii) L is the leverage of the CIS calculated in accordance with section 226ZJ(2)(b) of the BCR. (See Part IIIa and IIIb – Annex B for numerical examples) B.4 Reporting of On-balance Sheet Exposures – Columns A1 and A2 in Division A
37. If an on-balance sheet exposure is not covered by any recognized CRM, the whole
principal amount (after deduction of specific provisions3 ) of the exposure should be reported in both columns A1 and A2 of the row for the exposure class and risk-weight applicable to the exposure. If the exposure is a defaulted exposure, the whole principal amount (after deduction of specific provisions) should be reported in columns A1 and A2 of item 16a or 16b, as the case requires, under Class XVI.
38. If an on-balance sheet exposure is covered fully or partially by recognized CRM—
(a) the whole principal amount (after deduction of specific provisions) of the exposure should be reported in column A1 of the row for the exposure class and risk-weight applicable to the exposure; and (b) column A2 should be filled in as set out in paragraphs 39 and 40 below.

39. CRM treatment by substitution of risk-weights (applicable to collateral under the simple
approach 4
, guarantees and credit derivative contracts) (a) The amount reported in column A1 should be divided into the credit protection covered portion(s) and the credit protection uncovered portion. (b) Each credit protection covered portion of the exposure should be reported in column A2 as follows— (i) if the exposure is not a defaulted exposure, it should be reported in the row for the exposure class and risk-weight applicable to the credit protection concerned. That is— (A) in the case of collateral, the credit protection covered portion should be allocated the risk-weight of the collateral (the risk-weight is subject to a floor of 20% unless otherwise stated in the BCR); or (B) in the case of a guarantee or credit derivative contract, the credit protection covered portion should be allocated the attributed risk-weight of the credit protection provider (or the risk-weight of 2% or 4% if the credit derivative contract falls within section 100(7) of the BCR); or (ii) if the exposure is a defaulted exposure, it should be reported in item 16c(i), (ii), (iii) or (iv) of Class XVI (Defaulted Exposures), depending on the range within which the risk-weight applicable to the credit protection falls. (c) The credit protection uncovered portion of the exposure, if any, should be reported in column A2 of the row for the exposure class and risk-weight applicable to the exposure. (d) In the case of— (i) mortgage loans granted for the purchase of flats under the Home Ownership Scheme, Private Sector Participation Scheme, Tenants Purchase Scheme and other similar schemes which are covered by guarantees issued by Hong Kong Housing Authority; (ii) reverse mortgage loans granted under the Reverse Mortgage Programme of HKMC Insurance Limited; and (iii) mortgage loans granted under Mortgage Insurance Programme of HKMC Insurance Limited, the credit protection uncovered portion, if any, of the mortgage loans should be reported in column A2 under Class XIA. The credit protection covered portion of the mortgage loans in relation to the guarantee provided by Hong Kong Housing Authority or the insurance provided by HKMC Insurance Limited should be reported in Class II and column A2 of the item for the risk-weight applicable to domestic

under the comprehensive approach and on-balance sheet netting) The net credit exposure calculated under section 87 or 94 of the BCR, as the case requires should be reported in the exposure class to which the exposure belongs and in column A2 of the row for the risk-weight applicable to the exposure. To avoid doubt, if the net credit exposure calculated under section 94 is a defaulted exposure, the AI should report the exposure in column A2 of item 16a or 16b in Class XVI, as the case requires. B.5 Reporting of Off-balance Sheet Exposures other than Default Risk Exposures – Columns A3 and A4 in Division A
41. Off-balance sheet exposures (except default risk exposures and credit exposures arising
from unsegregated collateral posted)

46. If the reporting AI issues a CLN to cover a default risk exposure, the amount of the
proceeds received from the issuance of the CLN should not be included in the calculation of the amount of the default risk exposure under Division 1A, 2 or 2B of Part 6A of the BCR. The AI may only take into account the CRM effect of the proceeds in the calculation of the RWA of the default risk exposure in accordance with section 101(8) of the BCR.

   This item also captures off-balance sheet exposures arising from the reporting AI’s commitments to subscribe to CISs’ future capital calls. To avoid doubt, forward start repo-style transactions should be reported in item 10b or c instead of this item.
7. Partly paid-up shares and securities

MA(BS)3(IIIb)/P.21 (03/2025)
8. Forward forward deposits placed
This refers to a commitment of the reporting AI to place a forward forward deposit. If the reporting AI has contracted to receive a forward forward deposit, failure to deliver by the counterparty will result in an unanticipated change in the AI’s interest rate exposure and may involve a replacement cost. Such exposure should therefore be regarded as default risk exposures arising from interest rate contracts and reported in Part II or IV of Division B, as the case requires.
9. Note issuance and revolving underwriting facilities
10a. to c. Other commitments
Included is the undrawn portion of any arrangement that falls within the definition of “commitment” defined in section 2 of Schedule 6 to the BCR and does not fall within any of items 1 to 9. A commitment is regarded as being created no later than the acceptance in writing by the customer of the facility offered. In the case of an off-balance sheet exposure (exposure A) arising from a commitment the drawdown of which will give rise to another off-balance sheet exposure (exposure B) falling within any of items 1 to 9 and 11, the CCF applicable to exposure A should be the lower of— (a) the CCF applicable to exposure A according to Schedule 6 to the BCR; and (b) the CCF applicable to exposure B according to that Schedule. 10a. Exempt commitments 10b. Other commitments (CCF at 10%) This item captures commitments (other than exempt commitments) that— (a) may be cancelled at any time unconditionally by the reporting AI concerned without prior notice; or (b) provide for automatic cancellation due to deterioration in the creditworthiness of the persons to whom the reporting AI has made the commitments. 10c. Other commitments (CCF at 40%) This item captures commitments that do not fall within items 10a and 10b. 11a. to d. Off-balance sheet exposures not specified above

MA(BS)3(IIIb)/P.22 (03/2025)
11a. This item captures off-balance sheet exposures that do not fall within items 1 to 10c and that are subject to a CCF of 100%. Such exposures include, but not limited to— (a) off-balance sheet exposures to the credit risk of the underlying assets of cash-settled derivative contracts (e.g. equity forward contracts) booked in the reporting AI’s banking book; and (b) credit exposures to persons holding unsegregated collateral posted by the reporting AI (other than collateral posted that is included in the default risk exposures reported in Part II, III or IV of Division B of this Form and Form MA(BS)3(IIIe)) (see section 71(2) of the BCR). 11b. to d. These items capture off-balance sheet exposures that do not fall within items 1 to 10c and that are subject to a CCF specified in Part 2 of Schedule 1 to the BCR. For other off-balance sheet exposures not mentioned above, the reporting AI should consult the HKMA on the reporting arrangements.
53. The reporting AI should report each of its off-balance sheet exposures as follows:
(a) report in column B2 the principal amount (net of specific provisions if applicable) of the exposure; (b) report in column B3 the CEA of the exposure (i.e. the product of the amount reported in column B2 and the applicable CCF specified in column B1); and (c) report the CEA of the exposure in one of columns B4 to B12 8 if the exposure falls within any one of the following exposure classes— (i) Class I Sovereign Exposures; (ii) Class II Public Sector Entity Exposures; (iii) Class III Multilateral Development Bank (MDB) Exposures 9 ; (iv) Class IV Unspecified Multilateral Body Exposures 9 ; (v) Class V Bank Exposures; (vi) Class VII Qualifying Non-bank Financial Institution (QNBFI) Exposures; (vii) Class VIII Corporate Exposures; (viii) Class IX Retail Exposures; (ix) Class XIA Regulatory Residential Real Estate Exposures 10;

8 Only breakdown by major exposure classes is required. As a result, for each row, the total amount reported in column B3 would be greater than or equal to the sum of the total amounts reported in columns B4 to B12. 9 To be reported in column B6. 10 To be reported in column B11.

C.3 Part II of Division B - Default Risk Exposures in respect of Derivative Contracts 11 (SA-CCR Approach)
54. If the reporting AI uses the SA-CCR approach to calculate default risk exposures, it
should report the exposures so calculated in the appropriate items in Part II of Division B (please see Part IIIa and IIIb – Annex A for numerical examples). Item no. Nature of item
12. Unmargined contracts not covered by recognized netting
This item captures derivative contracts—
(a) that fall within the definition of unmargined contract in section 226BA of the BCR; and (b) that are not covered by recognized netting. The following contracts should also be reported in this item— (a) contracts that fall within section 226BH(2) or (4) of the BCR; and (b) contracts that have been removed from the netting sets concerned under
section 226BH(3)(b) or (5) of the BCR.
13. Margined contracts not covered by recognized netting
This item captures derivative contracts—
(a) that fall within the definition of margined contract in section 226BA of the BCR; and (b) that are not covered by recognized netting.
14. Contracts covered by recognized netting
This item captures derivative contracts (whether they are margined contracts or not) covered by recognized netting.

11 Derivative contracts include long settlement transactions that fall within paragraph (c) or (d) of the definition of “derivative contract” in section 2(1) of the BCR. For example, a long settlement transaction that is a FX spot transaction must be reported as an exchange rate contract.

MA(BS)3(IIIb)/P.24 (03/2025)
15. Out of the amounts reported in items 12, 13 and 14, the amounts for
offsetting or CCP-related transactions with clearing members or clearing clients This item is for reporting the amounts captured under items 12 to 14 that are related to offsetting transactions or CCP-related transactions entered into by the reporting AI with clearing members or clearing clients (see Part IIIe – Annex A and paragraph 5 of the completion instructions for Form MA(BS)3(IIIe) for more information on exposures related to centrally cleared transactions that should be reported in this Form).
55. For all items in Part II of Division B—
(a) if a netting set contains a credit derivative contract that falls within section 226BI of the BCR and the reporting AI has— (i) treated the default risk exposure of such credit derivative contract as zero; and (ii) removed such credit derivative contract from the netting set (i.e. the default risk exposure of the netting set is calculated as if the credit derivative contract did not exist), the reporting AI is not required to report such credit derivative contract in Part II of Division B 12; (b) the amount reported in column B13 is the gross sum of the stated notional amounts of the relevant derivative contracts.
56. For item 12—
(a) report in column B14 the replacement cost of a derivative contract calculated in accordance with Division 1A of Part 6A of the BCR by using the formula applicable to the contract. In the case of a sold option whose default risk exposure is set to zero under 226BH(2) or (3) of the BCR, the replacement cost of the option may be reported as zero; (b) report in column B15 the potential future exposure of the derivative contract calculated in accordance with Division 1A of Part 6A of the BCR by using the formulas applicable to the asset class into which the contract falls. In the case of a sold option whose default risk exposure is set to zero under section 226BH(2) or (3) of the BCR, the potential future exposure of the option may be reported as zero; (c) report in column B16 the default risk exposure of the derivative contract (i.e. the sum of the amounts reported in columns B14 and B15 multiplied by 1.4); and

12 This is to avoid double counting as the notional amount of the credit derivative contracts is somehow reflected in the amount reported in Division A (e.g. credit protection covered portion) or Part I of Division B (e.g. direct credit substitute).

MA(BS)3(IIIb)/P.25 (03/2025)
(d) report the default risk exposure of the derivative contract in one of columns B17 to B23 13 if— (i) the counterparty to the contract is a sovereign, PSE, MDB, unspecified multilateral body, bank, QNBFI or corporate; or (ii) the default risk exposure falls within Class IX Retail Exposures.
57. The reporting arrangements mentioned in paragraph 56 also apply to item 13. Also—
(a) if the default risk exposure calculated for a margined contract on an unmargined basis is regarded as the default risk exposure of the contract, the default risk exposure calculated on an unmargined basis should be reported in column B16 (see section 226BH(1) of the BCR); (b) if more than one derivative contract is covered by a single variation margin agreement— (i) the stated notional amount of each of the derivative contracts should be reported in column B13 of item 13a, 13b, 13c, 13d or 13e, as the case requires; (ii) there is no need to report the replacement cost, potential future exposure and default risk exposure calculated for these contracts by type of contract. The amounts calculated under sections 226BE(3), 226BS and 226BE(2) of the BCR should be reported in columns B14, B15 and B16 of item 13f respectively.
58. For item 14, the replacement cost, potential future exposure and default risk exposure of
a netting set or a group of netting sets, as the case may be, should be reported in the row “SUBTOTAL” of columns B14, B15 and B16 respectively. The reporting arrangements mentioned in paragraphs 56(c) and 56(d) and paragraph 57(a) apply to the netting set or the group of netting sets as they apply to a single derivative contract. C.4 Part III of Division B - Default Risk Exposures in respect of SFTs (Non-IMM(CCR) Approach)
59. If the reporting AI calculates default risk exposures in respect of SFTs under Division 2B
of Part 6A of the BCR, it should report the exposures so calculated in the appropriate items in Part III of Division B as follows:
(a) The principal amount of the securities sold or lent, or the money paid or lent, or the securities or money provided as collateral, by the reporting AI under an SFT should be reported in column B24 of item 16a or 16b, as the case requires. (b) Under item 16a, if any one of section 226MJ(1)(a), (b)(i) or (b)(ii) is applicable to the reporting AI or its SFT, the AI’s SFT should be reported as follows—

13 Only breakdown by major exposure classes is required. As a result, for each row, the total amount reported in column B16 would be greater than or equal to the sum of the total amounts reported in columns B17 to B23.

MA(BS)3(IIIb)/P.26 (03/2025)
(i) report in column B25 the default risk exposure of the SFT calculated under
section 226MJ of the BCR; and
(ii) report the default risk exposure in one of columns B26 to B31 14 if the counterparty to the SFT is a sovereign, PSE, MDB, unspecified multilateral body, bank, QNBFI or corporate. (c) Under item 16b, nettable 15 SFTs with a counterparty should be reported as follows— (i) report in column B25 the default risk exposure of the nettable SFTs calculated under section 226MK of the BCR; and (ii) report the default risk exposure in one of columns B26 to B31 16 if the counterparty to the nettable SFTs is a sovereign, PSE, MDB, unspecified multilateral body, bank, QNBFI or corporate. (d) Item 16c is for reporting the amounts captured under items 16a and 16b that are related to offsetting transactions or CCP-related transactions entered into by the reporting AI with clearing members or clearing clients (see Part IIIe – Annex A and paragraph 5 of the completion instructions for Form MA(BS)3(IIIe) for more information on exposures related to centrally cleared transactions that should be reported in this Form). C.5 Part IV of Division B - Default Risk Exposures (IMM(CCR) Approach)
60. If the reporting AI uses the IMM(CCR) approach to calculate default risk exposures, it
should report the exposures so calculated in the appropriate items in Part IV of Division B. Item no. Nature of item
17. Portfolio-level risk-weighted amount based on current market data
The portfolio-level RWA calculated under section 226D(1)(a) and (2)(a) of the BCR should be reported in this item.
18. Portfolio-level risk-weighted amount based on stress calibration
The portfolio-level RWA calculated under section 226D(1)(b) and (2)(b) of the BCR should be reported in this item. Only the higher of item 17 and item 18 will be used in the calculation of the total RWA for credit risk under the STC approach.

14 Only breakdown by major exposure classes is required. As a result, for each row, the total amount reported in column B25 would be greater than or equal to the sum of the total amounts reported in columns B26 to B31. 15 For the purposes of this Form, an SFT is regarded as not nettable if the SFT is covered by recognized netting but the reporting AI uses the simple approach to take into account the CRM effect of the recognized collateral received under the SFT. 16 See footnote 14.

MA(BS)3(IIIb)/P.27 (03/2025)
19. to 22. Items 19 to 22 capture the breakdown of the default risk exposures included
in the portfolio-level RWA that will be used in the capital adequacy ratio calculation. In other words, if the portfolio-level RWA calculated using current market data is larger, the default risk exposures reported in items 19 to 22 should be those used in calculating the RWA reported in item 17.
19. Netting sets (not subject to recognized netting)
This item captures transactions—
(a) that are not subject to recognized netting; or (b) that are required to be treated as a separate netting set under section 226J(1) of the BCR. If the reporting AI’s IMM(CCR) approval covers one or more than one of the following categories of transactions:
(a) derivative contracts (excluding long settlement transactions (LSTs)); (b) SFTs (excluding LSTs); and (c) LSTs, the AI should report each of its transactions in item 19a, 19b or 19c based on the category within which the transaction falls.
20. Netting sets (subject to valid bilateral netting agreements)
This item captures transactions—
(a) that are subject to valid bilateral netting agreements; and (b) that are not required to be treated as a separate netting set under section 226J(1) of the BCR. Derivative contracts and SFTs covered by the reporting AI’s IMM(CCR) approval must be reported in items 20a and 20b respectively. The amounts reported in these two items will include derivative contracts and SFTs that are LSTs unless these LSTs are not covered by the IMM(CCR) approval. If the reporting AI’s IMM(CCR) approval only covers LSTs, the AI should report the LSTs in item 20c.
21. Netting sets (subject to valid cross-product netting agreements)
This item captures transactions—
(a) that are subject to valid cross-product netting agreements; and (b) that are not required to be treated as a separate netting set under section 226J(1) of the BCR.

MA(BS)3(IIIb)/P.28 (03/2025)
LSTs are included unless the IMM(CCR) approval of the reporting AI does not cover LSTs.
22. Out of the amounts reported in items 19, 20 and 21, the amounts for
offsetting or CCP-related transactions with clearing members or clearing clients This item is for reporting the amounts captured under items 19 to 21 that are related to offsetting transactions or CCP-related transactions entered into by the reporting AI with clearing members or clearing clients (see Part IIIe –
Annex A and paragraph 5 of the completion instructions for Form
MA(BS)3(IIIe) for more information on exposures related to centrally cleared transactions that should be reported in this Form).
61. The reporting AI should report the default risk exposures calculated under the IMM(CCR)
approach in Part IV of Division B of this Form as follows:
(a) report in column B33 of items 19a, 19c, 20a, 20c, 21a and 22a the gross sum of the stated notional amounts of the derivative contracts and LSTs concerned; (b) report in column B34 of items 19b, 19c, 20b, 20c, 21b, 21c and 22a the principal amounts of the securities sold, lent or delivered, or the money paid, by the AI to the counterparties under the SFTs and LSTs concerned; (c) report in column B35 of items 19a to 20c, 21 and 22a the default risk exposures of the netting sets concerned calculated under section 226E of the BCR. In the case of item 19, the netting set only contains one transaction; and (d) report the default risk exposure of each of the netting sets reported in column B35 in one of columns B36 to B41 17 if the counterparty to the netting set is a sovereign, PSE, MDB, unspecified multilateral body, bank, QNBFI or corporate.
62. If a netting set contains a credit derivative contract that falls within section 226I of the
BCR and the reporting AI has—
(a) treated the default risk exposure of such credit derivative contract as zero; and (b) removed such credit derivative contract from the netting set (i.e. the default risk exposure of the netting set is calculated as if the credit derivative contract did not exist), the reporting AI is not required to report such credit derivative contract in Part IV of Division B of this Form 18 .

17 Only breakdown by major exposure classes is required. As a result, for each row, the total amount reported in column B35 would be greater than or equal to the sum of the total amounts reported in columns B36 to B41. 18 See footnote 12.

MA(BS)3(IIIb)/P.29 (03/2025)
C.6 Multiple Credit Risk Mitigation
63. If an exposure is covered by two or more forms of recognized CRM (e.g. with both
collateral and guarantee partially covering the exposure), the treatments for the recognized CRM are set out in section 102(1) and (2) of the BCR. The calculation of the RWA of each portion will be done separately.
64. If an exposure is covered by credit protection provided by a single credit protection
provider but the credit protection has different maturities, the treatment for the credit protection is set out in section 102(3) of the BCR. The RWA of each portion should be calculated separately.
65. Unless otherwise stated in the BCR (e.g. section 78(1C)), the reporting AI may determine,
at its discretion, how recognized CRM that is shared by two or more on-balance sheet and/or off-balance sheet exposures are allocated to each of the exposures for the purpose of RWA calculation, as long as the AI’s allocation is not inconsistent with the terms and conditions of the relevant legal documentation. C.7 Maturity Mismatches
66. If a credit protection in the form of collateral, guarantee, credit derivative contract or on￾balance sheet netting has maturity mismatch referred to in section 103(1) of the BCR, a
reporting AI should determine whether the credit protection can be taken into account in the RWA calculation (see section 103(2) of the BCR for details) and whether the value of the credit protection should be adjusted (see Formula 12 in section 103(1) of the BCR). Adjustment to the value of credit protection does not apply to collateral without a finite maturity (e.g. equities). The maturity of a credit protection should be determined in accordance with section 103(3) and (4) of the BCR. Hong Kong Monetary Authority March 2025

Part IIIa and IIIb – Annex A
Examples of calculation of default risk exposure under the SA-CCR approach  The counterparty of the derivative contracts in each of the cases below is an unrated corporate that is not a small business and the AI concerned has not made use of any recognized guarantee or recognized credit derivative contract to mitigate the default risk exposure to the corporate arising from these contracts. Case 1: Unmargined contracts not covered by recognized netting In this case, since the derivative contracts entered into by the AI with the corporate are not covered by recognized netting, each contract forms a single netting set. Also, neither the AI nor the counterparty has posted collateral for the contracts.

𝑆𝐷𝐴1 =
𝑒𝑥𝑝(−0.05∗0)−𝑒𝑥𝑝(−0.05∗0.25)

Step 2.2: Calculation of effective notional amount (Di) at the level of hedging set For unmargined contract i not subject to recognized netting, the effective notional amount of a hedging set is equivalent to the effective notional amount of contract i and is given by the following formula:
𝐷𝑖 = 𝛿𝑖 ∗ 𝑑𝑖 ∗ 𝑀𝐹𝑖
(𝑢𝑛𝑚𝑎𝑟𝑔𝑖𝑛𝑒𝑑) where 𝑀𝐹𝑖
(𝑢𝑛𝑚𝑎𝑟𝑔𝑖𝑛𝑒𝑑) is the maturity factor applicable to contract i given by the following formula (Mi is subject to a floor of 10 business days):

Step 2.3: Calculation of add-on at the level of netting set For an interest rate1 or credit-related2 derivative contract not covered by recognized netting, the add-on for the netting set concerned is calculated as follows:

For a netting set that contains only one contract, if the contract is an interest rate contract, Formulas 23AS and 23AT in §226BU(2) of the BCR should result in the same effective notional amount for the contract. That is- 𝐸𝑓𝑓𝑒𝑐𝑡𝑖𝑣𝑒 𝑁𝑜𝑡𝑖𝑜𝑛𝑎𝑙(𝐼𝑅) = |𝐷 (𝑀𝐵) | where D (MB) is the effective notional amount for the maturity bucket in which the contract falls. However, since there is only one maturity bucket in the netting set, the actual calculation does not require allocation of the contract into a maturity bucket. 2 For a netting set that contains only one contract, if the contract is a credit-related derivative contract, Formula 23AQ in §226BT(3) of the BCR will be reduced to – 𝐴𝑑𝑑𝑂𝑛(𝑐𝑟𝑒𝑑𝑖𝑡) = [𝐴𝑑𝑑𝑂𝑛(𝐸𝑛𝑡𝑖𝑡𝑦𝑘 ) 2 ]

For netting set B− 𝑚𝑢𝑙𝑡𝑖𝑝𝑙𝑖𝑒𝑟𝑛𝑒𝑡𝑡𝑖𝑛𝑔 𝑠𝑒𝑡 𝐵 = min {1; 5% + (1 − 5%) ∗ 𝑒𝑥𝑝 ( −25 2∗(1−5%)∗221.2 )} = 0.945

As there are multiple netting sets covered by the same variation margin agreement, the potential future exposure of each of Contract A4 and Contract A5 must be calculated in a manner as if the contracts were unmargined contracts (see §226BS of the BCR). Accordingly, the maturity factor of each of the contracts is calculated by using the formula for unmargined contracts. 𝑀𝐹𝑖 (𝑢𝑛𝑚𝑎𝑟𝑔𝑖𝑛𝑒𝑑) = √ 𝑚𝑖𝑛{𝑀𝑖 ; 1 𝑦𝑒𝑎𝑟} 1 𝑦𝑒𝑎𝑟 𝑀𝐹𝐴4 (𝑢𝑛𝑚𝑎𝑟𝑔𝑖𝑛𝑒𝑑) = √ 𝑚𝑖𝑛{0.25; 1} 1 = 0.5 𝑀𝐹𝐴5 (𝑢𝑛𝑚𝑎𝑟𝑔𝑖𝑛𝑒𝑑) = √ 𝑚𝑖𝑛{0.4; 1} 1 = 0.6325 Step 2.3: Calculation of add-on at the level of netting set Contract Effective notional amount (Di) (HK$’000) (a) Supervisory factor (SF) (b) Add-on3 (HK$’000) = (a) × (b) A4 69 32% 22.03 A5 4,984 4% 199.36

Step 3: Calculation of potential future exposure (PFE) of netting sets covered by margin agreement MA Step 3.1: Calculation of multiplier of each netting set As the same collateral is shared by four netting sets and the AI in this example is a net receiver of collateral (C>0), netting sets with positive market values must first be allocated collateral up to the amount of those market values. Only after all positive market values have been compensated may surplus collateral be attributed freely among all netting sets. Also, the allocated parts must add up to the total collateral available for the margin agreement. Apart from these limitations, AIs may allocate available collateral at their discretion. The following
table shows the multipliers calculated by using one of the possible collateral allocations.

*The allocation is for illustrative purpose only and does not represent any preference of the HKMA. From Case 1, the multiplier of netting set B is 0.945. The multipliers of other netting sets are calculated as follows:

Case 3: Unmargined contracts covered by recognized netting In this case, the contracts involved are the same as contracts A1, A2 and A3 in Case 1, except that the three contracts are covered by recognized netting and therefore fall within the same netting set. Also, neither the AI nor the counterparty has posted collateral for the contracts.

The effective notional amount of the hedging set that contains contracts A1 and A2 is calculated by using Formula 23AS in §226BU(2) of the BCR as follows:
𝐸𝑓𝑓𝑒𝑐𝑡𝑖𝑣𝑒 𝑁𝑜𝑡𝑖𝑜𝑛𝑎𝑙ℎ𝑒𝑑𝑔𝑖𝑛𝑔 𝑠𝑒𝑡 = [(𝐷𝐴1 ) 2 + (𝐷𝐴2 ) 2 + 1.4 ∙ 𝐷𝐴1 ∙ 𝐷𝐴2 ] 0.5 = [(1,242) 2 + (−44,240) 2 + 1.4 ∗ (1,242) ∗ (−44,240)]
0.5 = 43,379.67

16
Step 2.2: Calculation of add-on at the level of asset class Given the effective notional amounts calculated under Step 2.1, the add-on for each asset class is calculated as follows:

Case 4: Margined contracts covered by recognized netting In this case, the contracts involved are the same as Case 2 and subject to the same margin agreement as described in Case 2, except that the contracts are covered by the same valid bilateral netting agreement and therefore fall within the same netting set.
I. Calculation of default risk exposure
Step 1: Calculation of replacement cost (RC) at the level of netting set RC = max (V – C ; TH + MTA – 𝑁𝐼𝐶𝐴; 0) 𝑉 = 10 − 25 + 11 + 16 = 12 RC = max (12 – 500 ; 0 + 5 – 450; 0) = 0 Step 2: Calculation of add-on at the level of netting set Step 2.1: Calculation of contract-level effective notional amount (Di) From Cases 1 and 2, we have the following information on each of the derivative contracts:

A4 NA +0.588 234 0.3 41.31
A5 NA +1 7,881 0.3 2,364.17
The maturity factor for margined transactions depends on the margin period of risk (MPOR). For daily re-margining, the MPOR is at least 10 business days. In this example, the contracts are not centrally cleared and the requirements in §226BZE(3), (4) and (6) do not apply to the contracts. Hence, the maturity factor for the contracts in the netting set is as follows (the convention of 250 business days in a year is used):

250 = 0.3
Step 2.2: Calculation of effective notional amount (Di) at the level of hedging set Contracts A1 and A2 are in the same hedging set but in different maturity buckets. The effective notional amount of the hedging set is calculated by using Formula 23AS in §226BU(2) of the BCR as follows:
𝐸𝑓𝑓𝑒𝑐𝑡𝑖𝑣𝑒 𝑁𝑜𝑡𝑖𝑜𝑛𝑎𝑙 = [(𝐷𝐴1 ) 2 + (𝐷𝐴2 ) 2 + 1.4 ∙ 𝐷𝐴1 ∙ 𝐷𝐴2 ] 0.5 = [(745.33) 2 + (−13,271.95) 2 + 1.4 ∗ (745.33) ∗ (−13,271.95)]
0.5 = 12,761.33
In the case of Contracts A4 and A5, each contract forms its own hedging set. Hence, the effective notional amount of each hedging set is same as the contract-level effective notional amount. Step 2.3: Calculation of add-on at the level of asset class Given the effective notional amounts calculated under Step 2.2, the add-on for each asset class is calculated as follows:

Examples of calculation of risk-weighted amount of CIS exposure with portion constituting deductible holding The following examples deliberately incorporate certain assumptions for the sake of simplicity and ease of illustration. When determining the amount of capital deduction and the amount subject to risk-weighting for capital instruments or non-capital LAC liabilities in an actual case, AIs should always refer to and follow the relevant provisions set out in Division 4 of Part 3 (including the relevant schedules) of the BCR. The reporting arrangements are intended to illustrate what principal amounts should be reported when the collective investment scheme concerned has a leverage level of more than 1. Although risk-weights under the STC approach are used in the examples for illustration, the calculation steps illustrated also apply to the BSC approach. Example 1: Capital instruments held by a Level 1 CIS Consider a Level 1 CIS that has the following balance sheet:
Asset
Cash $20
CET1 capital instruments issued by:
— financial sector entity A $100
— financial sector entity B $100
Debt securities (A rated) issued by sovereigns $280 Listed equities issued by — Commercial entity A $100 — Other commercial entities $400 Liabilities Note payable $50 Equity Shares $950 Moreover, assume the following:
 an AI using the STC approach owns 20% of the shares of the Level 1 CIS and the principal amount of the AI’s equity investment in the Level 1 CIS (PCIS exposure) is $190;

2
 financial sector entities A and B and commercial entity A have the following relationship with the AI:
— the AI owns less than 10% of the issued ordinary share capital of financial sector entity A and owns more than 10% of the issued ordinary share capital of financial sector entity B. Both financial sector entities are not subject to a section 3C requirement and they are not affiliates of the AI; and — commercial entity A is an affiliate of the AI; and  none of the listed equities held by the Level 1 CIS are required to be deducted from the AI’s CET1 capital under §43 of the BCR. Moreover, the other commercial entities are not affiliates of the AI and the AI does not have any shareholdings in them. Portion of the AI’s CIS exposure that constitutes deductible holding (§70A) Given— (a) total amount of regulatory deductible items held by the Level 1 CIS (PRDI) = $100 + $100 = $200; (b) total assets of the Level 1 CIS (TA) = $1000; and (c) equity of the Level 1 CIS (TE) = $950, amount of the AI’s CIS exposure to the Level 1 CIS that constitutes deductible holding (PDH) is calculated as follows:
𝑃𝐷𝐻 =
(𝑃𝑅𝐷𝐼)
(𝑇𝐴)
∙ 𝑃𝐶𝐼𝑆 𝑒𝑥𝑝𝑜𝑠𝑢𝑟𝑒
=
(200)
(1000)
∙ (190) = 38
However, since the Level 1 CIS uses leverage, the AI’s actual exposure to the regulatory deductible items = leverage of Level 1 CIS × PDH = (1000) (950) ∙ (38) = 40 Alternatively, the AI may calculate the amount of its indirect holding of the regulatory deductible items by multiplying PRDI by 20% = 200 × 20% = 40

3
Amount of the AI’s deductible holding subject to capital deduction After applying all the relevant provisions in Division 4 of Part 3 (including relevant schedules) of the BCR, the AI determines that the total amount of the deductible holding that must be deducted from its CET1 capital is $34. RWA of the AI’s deductible holding not subject to capital deduction RWA = (4×250%) + (2×250%) = $15 Principal amount Risk￾weight RWA Capital deduction CET1 capital instruments issued by:
— financial sector entity A

Example 2: Capital instruments held by a Level 2 CIS Consider a Level 1 CIS that has the following balance sheet:
Asset
Cash $20
CIS exposure to a Level 2 CIS $40
Debt securities (A rated) issued by sovereigns $580 Listed equities $360 Liabilities Note payable $50 Equity Shares $950 Moreover, assume the following:
 an AI using the STC approach owns 20% of the shares of the Level 1 CIS and the principal amount of the AI’s equity investment in the Level 1 CIS (PCIS exposure) is $190; and  the AI is able to use the LTA to calculate the RWAs of the underlying exposures of the Level 1 CIS and the Level 2 CIS. The following is the balance sheet of the Level 2 CIS:
Asset
Cash $10
CET1 capital instruments issued by financial sector entity A $200 Debt securities (A rated) issued by sovereigns $190 Listed equities $400 Liabilities Note payable $0 Equity Shares $800  The AI owns less than 10% of the issued ordinary share capital of financial sector entity A which is neither an entity subject to a section 3C requirement nor an affiliate of the AI.

7
 None of the listed equities held by the Level 1 CIS and the Level 2 CIS are required to be deducted from the AI’s CET1 capital under §43 of the BCR. Moreover, none of these equities are issued by commercial entities that are affiliates of the AI. The AI also does not have any shareholdings in the commercial entities. Step 1: Level 1 CIS’s CIS exposure to Level 2 CIS Under the LTA, the RWA of the Level 1 CIS’s CIS exposure to the Level 2 CIS (RWA CIS expo 2) is calculated as follows:
𝑅𝑊𝐴𝐶𝐼𝑆 𝑒𝑥𝑝𝑜 2 =
𝑃𝑅𝐷𝐼∙𝑅𝑊𝑅𝐷𝐼+𝑅𝑊𝐴𝑛𝑜𝑛−𝑅𝐷𝐼
𝑇𝐴2

(a) PRDI is the amount of regulatory deductible items held by the Level 2 CIS; (b) RWRDI is the risk-weight1 applicable to the regulatory deductible items; (c) RWAnon-RDI is the RWA of the underlying exposures of the Level 2 CIS that are not regulatory deductible items; (d) TA2 is the total assets of the Level 2 CIS; (e) TE2 is the equity of the Level 2 CIS; and (f) PCIS expo 2 is the CIS exposure of the Level 1 CIS to the Level 2 CIS. By rearranging equation (1) above, the CIS exposure to the Level 2 CIS and its RWA can be divided into two portions— 𝑅𝑊𝐴𝐶𝐼𝑆 𝑒𝑥𝑝𝑜 2 = 𝑃𝑅𝐷𝐼 ∙ 𝑅𝑊𝑅𝐷𝐼 𝑃𝑅𝐷𝐼 ∙ 𝑇𝐴2 𝑇𝐸2 ∙ ( 𝑃𝑅𝐷𝐼 𝑇𝐴2 ∙ 𝑃𝐶𝐼𝑆 𝑒𝑥𝑝𝑜 2) + 𝑅𝑊𝐴𝑛𝑜𝑛−𝑅𝐷𝐼 𝑃𝑛𝑜𝑛−𝑅𝐷𝐼 ∙ 𝑇𝐴2 𝑇𝐸2 ∙ ( 𝑃𝑛𝑜𝑛−𝑅𝐷𝐼 𝑇𝐴2 ∙ 𝑃𝐶𝐼𝑆 𝑒𝑥𝑝𝑜 2) = 𝑃𝑅𝐷𝐼 ∙ 𝑅𝑊𝑅𝐷𝐼 ∙ %𝐿1 𝐶𝐼𝑆 + 𝑅𝑊𝐴𝑛𝑜𝑛−𝑅𝐷𝐼 𝑃𝑛𝑜𝑛−𝑅𝐷𝐼 ∙ 𝑇𝐴2 𝑇𝐸2 ∙ ( 𝑃𝑛𝑜𝑛−𝑅𝐷𝐼 𝑇𝐴2 ∙ 𝑃𝐶𝐼𝑆 𝑒𝑥𝑝𝑜 2)… (2) where— (a) %L1 CIS is the share of the Level 1 CIS in the equity of the Level 2 CIS; and (b) Pnon-RDI is the amount of underlying exposures (other than regulatory deductible items) held by the Level 2 CIS.

In order to illustrate how to identify the portion of a CIS exposure that contributes to the deductible holding of the AI, capital deduction is represented by the application of a risk-weight (i.e. 1250%) in the equations in this example.

For the portion of the CIS exposure in relation to underlying exposures other than regulatory deductible items (i.e. the portion that is subject to Part 6B of the BCR, where the regulatory deductible items are excluded in accordance with §226ZX(2)), the RWA of that portion is calculated as follows:

Part IIIb – Annex A
Illustrations on Reporting of Recognized Credit Risk Mitigation All monetary figures in HK$ million unless otherwise stated. Case 1: On-balance sheet exposure – collateralized loan  Exposure: A 5-year term loan of $1,000 to an unrated corporate, which is not a small business, incorporated in Hong Kong.  Collateral: Debt securities that are− — issued by a bank; — denominated in Euro; — rated AA by the Standard & Poor’s; and — maturing in 7 years.  The collateral is subject to daily revaluation and presently has a market value of $1,050. Simple Approach

1. Calculation of Risk-weighted Amount
    Exposure: Applicable risk-weight (RW) is 100% (see §61(2)(a) of the BCR).  Collateral: An AA-rating is mapped to a RW of 20% (see §59 (Table 3) of the BCR and the LT ECAI Rating Mapping Table for Type A ECAIs.  Credit protection covered portion: $1,000  Credit protection uncovered portion: $0  RWA of the loan calculated by substituting the RW of the corporate with the RW of the collateral: $1,000 × 20% = $200

    Standard supervisory haircut for currency mismatch: 8% (see item 3 in Table C in Schedule 7).  As the above standard supervisory haircuts only assume a 10-day holding period, they have to be scaled up to haircuts for 20-day holding period (which is the minimum holding period assumed for secured lending transactions) using Formula 5A in §91(3) of the BCR and Formula 33 in §3 of Schedule 7:

Case 2: Off-balance sheet exposure - collateralized loan commitment Now assuming that the corporate borrower in Case 1 has not yet drawn down the loan facility and the facility has an original maturity of 2 years (i.e. the borrower has to draw down the loan within 2 years). It is also assumed that the loan facility is not an exempt commitment and cannot be cancelled by the AI unconditionally. Simple approach

1. Calculation of Risk-weighted Amount
    CCF applicable to a commitment with an original maturity over 1 year: 40% (see item 12 of the Table in §1 of Schedule 6 to the BCR).  CEA of the commitment = $1,000 × 40% = $400  RWA of the commitment (with the RW of the corporate replaced by the RW of the collateral): $400 × 20% = $80

Case 3: Collateralized derivative contract covered by recognized guarantee  Interest rate contract with a notional of $1,000 with a four-year residual maturity.  Not subject to margin agreement and netting agreement.  The counterparty is an unrated corporate that is not a small business.  The contract is covered by a guarantee of $8 provided by a bank with an “A1” Moody’s rating.  It is assumed that the replacement cost and potential future exposure of the contract calculated under the SA-CCR approach are $1 and $18 respectively.

1. Calculation of Risk-weighted Amount
   Default risk exposure in respect of the interest rate contract is calculated as follows:
   𝐷𝑒𝑓𝑎𝑢𝑙𝑡 𝑅𝑖𝑠𝑘 𝐸𝑥𝑝𝑜𝑠𝑢𝑟𝑒 = 𝑎𝑙𝑝ℎ𝑎 ∗ (𝑅𝐶 + 𝑃𝐹𝐸) = 1.4 ∗ (1 + 18) = 26.6  RW applicable to the bank guarantee: 30%.  RWA of credit protection covered portion = $8 × 30% = $2.4  RWA of credit protection uncovered portion = ($26.6 - $8) × 100% = $18.6  Total RWA = $2.4 + $18.6 = $21

4. This return and its completion instructions should be read in conjunction with the BCR
and the relevant supervisory policy/guidance on the capital adequacy framework.

MA(BS)3(IIIc) /P.3 (03/2025)
Section A: General Instructions
I. Scope of the IRB Return
5. A reporting AI is required to report in this return its credit exposures subject to the IRB
approach in accordance with section 141 of the BCR.
6. To avoid doubt, a reporting AI using a combination of the standardized (credit risk)
approach (STC approach) and the IRB approach should report those exposures under the STC approach in Form MA(BS)3(IIIb) according to the reporting requirements.
II. Classification of Exposures
7. In reporting the IRB return, the reporting AI should classify each of its credit exposures
into one of the six IRB classes and then sub-classify each of these exposures into one of the twenty six IRB subclasses as shown in Table 16 to section 142 of the BCR and replicated below in accordance with the definitions given in paragraphs 13 to 21:

III. Choice of IRB Calculation Approaches
9. Under the IRB approach, a reporting AI may use the following IRB calculation
approaches (setting out in Table 17 to section 147 of the BCR) for each of the six IRB classes, provided that the relevant criteria and qualifying conditions are met:
IRB class IRB calculation approaches available Corporate exposures Foundation IRB approach Advanced IRB approach Supervisory slotting criteria approach Sovereign exposures Foundation IRB approach Advanced IRB approach Bank exposures Foundation IRB approach Retail exposures Retail IRB approach CIS exposures CIS calculation approach Other exposures Specific risk-weight approach
IV. Structure of the IRB Return
10. The IRB return consists of the following six divisions:
Division A: Summary of Risk-weighted Amount for Credit Risk under IRB Approach – showing the risk-weighted amount by IRB class/subclass and a breakdown of the risk-weighted amount for selected types of exposures; Division B: Risk-weighted Amount by IRB Class/Subclass – providing information on the credit risk components and risk-weighted amount of individual IRB subclasses or, where applicable, individual portfolio types; Division C: LGD for Corporate, Sovereign, Bank and Retail Exposures – providing supplementary information to Division B on LGD of individual IRB subclasses or, where applicable, individual portfolio types for corporate, sovereign and bank exposures under the foundation IRB approach or corporate and sovereign exposures under the advanced IRB approach;

MA(BS)3(IIIc) /P.6 (03/2025) and retail exposures under the retail IRB approach; Division D: Off-Balance Sheet Exposures (Other than Default Risk Exposure in respect of Derivative Contracts and SFTs) under IRB Approach – providing supplementary information to Division B by giving a breakdown of off-balance sheet exposures (other than derivative contracts and SFTs) for corporate, sovereign, bank and retail exposures; Division E: Default Risk Exposures in respect of Derivative Contracts and SFTs – providing supplementary information to Division B by giving a breakdown of derivative contracts and SFTs for corporate, sovereign, bank and retail exposures; and Division F: EL-EP Calculation under IRB Approach – providing a breakdown of the respective EL amount and eligible provisions for corporate, sovereign, bank and retail exposures and calculating the difference between the two, if any, for the computation of the capital base.
11. There are multiple Forms in Divisions B, C and E of this return for the reporting of
different IRB subclasses of exposures or exposures subject to different calculation methods. A list showing the reporting Forms under various divisions is given at Annex IIIc-B. For Divisions A, D and F, a reporting AI is required to report the positions of all relevant IRB classes/subclasses in one single Form. For Divisions B and C, the position of each IRB subclass (or, where applicable, each portfolio type) should be reported separately in the Form applicable to that IRB subclass (or that portfolio type). For Division E, the positions should be reported separately according to the methods the reporting AI adopts for the calculation of default risk exposures in respect of derivative contracts and SFTs.
12. Where a reporting AI uses more than one rating system for an IRB class/subclass 1
, the institution should split the exposures into portfolios according to the rating systems used and report each portfolio in one Form under Division B (and, where applicable, Division C). In addition, the reporting AI should provide a brief description of the nature of the portfolio under the item “portfolio type” of each separate Form. A reporting AI should consult with the HKMA on the appropriate reporting treatment if it has difficulties to report its exposures by portfolio in the above manner.
V. Definitions and Clarification
(A) Definition of IRB Classes and Subclasses Corporate Exposures
13. A reporting AI should, according to sections 143 and 197 of the BCR, classify each of
its exposures to corporates, including purchased corporate receivables, into one of the following IRB subclasses:

1 For example, a reporting AI may have more than one internal rating system for its qualifying revolving retail exposures (revolver), such as having separate scorecards for credit card lending and personal revolving loans.

(ix) other corporates Section 143(5)
Sovereign Exposures
14. According to section 142 of the BCR, sovereign exposures 2
include exposures which fall within one of the following IRB subclasses:
(i) sovereigns;
(ii) sovereign foreign public sector entities (SFPSEs); and (iii) multilateral development banks (MDBs). Bank Exposures
15. According to section 142 of the BCR, bank exposures include exposures which fall
within one of the following IRB subclasses:
(i) banks (excluding covered bonds);
(ii) qualifying non-bank financial institutions; (iii) public sector entities (PSEs) that are not SFPSEs; (iv) unspecified multilateral bodies; and (v) covered bonds.

2 Holdings of notes and coins should be reported as cash items under the IRB class of other exposures (see paragraph 21).

MA(BS)3(IIIc) /P.8 (03/2025)
Retail Exposures
16. In accordance with section 144(1) of the BCR, exposures to individuals which,
regardless of exposure size, are managed by the reporting AI on a pooled or portfolio basis should be classified as retail exposures. Retail exposures to individuals usually include residential mortgage loans, revolving credits (e.g. credit cards and overdrafts) and other personal loans (e.g. instalment loans, auto loans, tax loans, personal finance and other retail credits with similar characteristics). For those exposures which are not managed by the reporting AI on a pooled or portfolio basis, an institution should treat them as corporate exposures as per section 144(6) of the BCR.
17. Exposures to corporates may also be classified as retail exposures, provided that the
criteria set out in section 144(2) and (3)(b) of the BCR are met.
18. A reporting AI should, in accordance with sections 144 and 197 of the BCR, classify
each of its retail exposures, including purchased retail receivables, into one of the following IRB subclasses:
IRB subclass BCR reference
(i) small business retail exposures Section 144(2) (ii) residential mortgages (RM) to individuals
Section 144(3)
(iii) RM to property-holding shell companies (iv) qualifying revolving retail exposures (QRRE) (transactor)
Section 144(4)
(v) QRRE (revolver) Section 144(4A)
(vi) other retail exposures to individuals Section 144(5) CIS Exposures
19. A reporting AI must use the CIS calculation approach to calculate the risk-weighted
amount of a CIS exposure not constituting a deductible holding in accordance with Part 6B of the BCR.
20. For a CIS exposure constituting a deductible holding that is not deducted from the
capital base of the reporting AI under Division 4 of Part 3 of the BCR, the institution must calculate the risk-weighted amount of the exposure in accordance with section 183 of the BCR. Other Exposures
21. According to section 146 of the BCR, a reporting AI should classify under the IRB class
of other exposures any of its exposures which do not fall within the IRB class of corporate, sovereign, bank, retail or CIS exposures. These exposures include:
(i) cash items, the types of exposures covered are set out in the table under paragraph 88; and

MA(BS)3(IIIc) /P.9 (03/2025)
(ii) other items, which are other exposures that do not fall within the IRB subclass of cash items, e.g. premises, plant and equipment and other fixed assets for own use (see paragraph 90). (B) Clarification
22. Figures of percentage or year should be rounded up to two decimal points.
23. A reporting AI should report in the columns of “Exposures before recognized
guarantees / credit derivative contracts” the EAD of its on-balance sheet exposures and off-balance sheet exposures before adjusting for the credit risk mitigating effects of any recognized guarantee and recognized credit derivative contract. For instance:
(i) in respect of on-balance sheet exposures, the institution should report the EAD of such exposures both before and after adjusting for the credit risk mitigating effects of any recognized netting; (ii) in respect of off-balance sheet exposures (other than derivative contracts and SFTs), the institution should report the credit equivalent amount of such exposures; and (iii) in respect of off-balance sheet exposures which are derivative contracts and SFTs, the institution should report the default risk exposures of such transactions after adjusting for the credit risk mitigating effects of any recognized netting.
24. A reporting AI should report in the columns of “Exposures after recognized guarantees
/ credit derivative contracts” the EAD of its on-balance sheet exposures and off-balance sheet exposures after adjusting for the credit risk mitigating effects of any recognized netting, recognized guarantee and recognized credit derivative contract.
25. Principal amount, in respect of an off-balance sheet exposure, should be reported
without deduction of specific provisions and partial write-offs.
26. Double counting of exposures arising from the same contract or transaction should be
avoided. For example, only the undrawn portion of a loan commitment should be reported as an off-balance sheet exposure while the actual amount drawn should be reported as an on-balance sheet exposure. Trade-related contingencies, such as trust receipts and shipping guarantees, which have already been reported as letters of credit issued or loans against import bills etc. should not be counted again as off-balance sheet exposures.
27. In certain cases, counterparty default risk exposures arising from derivative contracts
may already be reflected, in part, on the reporting AI’s balance sheet. For example, a reporting AI may have recorded the fair value of a derivative contract on its balance sheet. To avoid double counting, such amount should be excluded from on-balance sheet exposures and treated as off-balance sheet exposures for the purposes of this return.
28. The accrued interest of a credit exposure should form part of the EAD of the credit

MA(BS)3(IIIc) /P.10 (03/2025) exposure. A reporting AI should therefore classify and risk-weight the accrued interest receivables in the same way as the principal amount of the respective credit exposures.

MA(BS)3(IIIc) /P.11 (03/2025)
Section B: Calculation of Risk-weighted Amount for Credit Risk under IRB Approach
I. Risk-weighted Amount under IRB Approach
29. The IRB approach is based on measures of unexpected loss (UL) and expected loss
(EL). The risk-weight functions in this section produce capital requirements for the UL portion. EL is treated separately as outlined in Section C.
30. A reporting AI should calculate the risk-weighted amount for the UL of its credit
exposures under the IRB approach as follows:
(i) the institution should calculate the risk-weighted amount of each exposure (except CIS exposures to which item (ii) applies and counterparty credit risk exposures to which item (iii) applies) by multiplying the EAD of each such exposure by the relevant risk-weight; (ii) in respect of a CIS exposure not constituting a deductible holding, the institution must calculate its risk-weighted amount in accordance with Part 6B of the BCR; (iii) in respect of derivative contracts or SFTs, the institution must calculate the risk￾weighted amount of the counterparty credit risk exposure - (a) if the institution has an IMM(CCR) approval 3 for its transactions or contracts, by aggregating -  the IMM(CCR) risk-weighted amount of the transactions or contracts concerned that are covered by the IMM(CCR) approval; and  the sum of the SA-CCR risk-weighted amount 4 or SFT risk-weighted amount 5 of the transactions or contracts concerned that are (i) not covered by the IMM(CCR) approval; or (ii) covered by the IMM(CCR) approval but fall within section 10B(5) or (7) of the BCR; (b) if the institution does not have an IMM(CCR) approval for any of its transactions or contracts, by aggregating -  the sum of the SA-CCR risk-weighted amount; and  the SFT risk-weighted amount; (iv) the institution should aggregate the risk-weighted amount figures derived from items (i), (ii) and (iii) to arrive at the total risk-weighted amount for credit risk under the IRB approach.

3 The term “IMM(CCR)” in “IMM(CCR) approval” refers to the internal models (counterparty credit risk) approach (IMM(CCR) approach) - see definitions in section 2(1) of the BCR. 4 The term “SA-CCR” in “SA-CCR risk-weighted amount” refers to the standardized (counterparty credit risk) approach - see definition in section 2(1) of the BCR. 5 See the definition of “SFT risk-weighted amount” in section 139(1) of the BCR.

MA(BS)3(IIIc) /P.12 (03/2025)
31. For the purposes of paragraph 30(iii), a reporting AI may, in the case of a default risk
exposure in respect of long settlement transactions (LSTs), determine the exposure’s relevant risk-weight using the STC approach on a permanent basis.
32. A reporting AI may reduce the risk-weighted amount of an exposure by taking into
account the effect of any recognized credit risk mitigation through adjusting the PD, LGD or EAD, as the case may be, in accordance with Part XIII of this section.
II. General Requirements for All IRB Classes
(A) General Requirements
33. There are three key elements for the calculation of the risk-weighted amount for the UL
portion under the IRB approach, including:
(i) credit risk components – these are estimates of PD, LGD, EAD, EL and M made by a reporting AI, or supervisory estimates specified in the BCR; (ii) risk-weight functions – these are the formulae by which credit risk components are transformed into risk-weighted amount and therefore capital requirements; and (iii) minimum requirements - the minimum standards which a reporting AI should meet for the use of the IRB approach 6 .
34. A reporting AI should use the risk-weight functions provided in sections 156 and 176
of the BCR for the purpose of calculating the risk-weighted amount, unless otherwise specified. In applying such risk-weight functions, PD and LGD are measured as decimals, EAD is measured in HK$ and M is measured in years.
35. For the purposes of calculating the EAD of an exposure (whether held on- or off￾balance sheet) that is measured at fair value, a reporting AI should comply with the
prudent valuation and valuation adjustment requirements in section 4A of the BCR. (B) Corporate, Sovereign and Bank Exposures
36. Under the foundation IRB approach, section 156(1)(a) of the BCR indicates a reporting
AI should provide its own estimates of PD associated with each of its obligor grades, but should use supervisory estimates for other credit risk components (i.e. LGD, EAD and M 7 ).
37. Under the advanced IRB approach, a reporting AI should provide its own estimates of
PD, LGD and EAD and calculate M according to section 156(1)(b) of the BCR.

6 Please refer to Part 6 and Schedule 2 of the BCR and the relevant supervisory policy/guidance relating to the IRB approach. 7 See footnote 13 for an optional alternative treatment for M.

MA(BS)3(IIIc) /P.13 (03/2025)
38. In respect of SL under the supervisory slotting criteria approach, a reporting AI should,
in accordance with section 156(1)(c) of the BCR, apply the supervisory estimate of a risk-weight that is applicable to a supervisory rating grade in calculating the risk￾weighted amount of such SL. (C) Retail Exposures
39. Under the retail IRB approach, section 170(1) of the BCR sets out that a reporting AI
should provide its own estimates of PD, LGD and EAD associated with each pool of retail exposures. There is no distinction between a foundation approach and an advanced approach for retail exposures. (D) CIS Exposures
40. The CIS calculation approach must be used to calculate a reporting AI’s risk-weighted
amount of CIS exposures.
(E) Other Exposures
41. Under the specific risk-weight approach, a reporting AI should apply a specific risk￾weight applicable to an exposure which falls within the IRB subclass of cash items (see
paragraph 88) or the IRB subclass of other items (see paragraph 90) in calculating the risk-weighted amount of the exposure according to sections 195 and 196 of the BCR.
III. Specific Requirements for Certain Exposure Portfolios
(A) Purchased Receivables (sections 197 to 200 of the BCR)
42. “Purchased receivables” straddles corporate and retail IRB classes. For purchased
corporate receivables, both the foundation IRB approach and the advanced IRB approach are available subject to the relevant minimum requirements being met. Like other retail exposures, there is no distinction between a foundation approach and an advanced approach for purchased retail receivables. For purchased receivables (whether corporate or retail), a reporting AI is required to calculate the risk-weighted amount for default risk and, if material, dilution risk of such purchased receivables (see
Part VIII of this section).
(B) Leasing Transactions (section 201 of the BCR)
43. There is a distinct treatment for calculating the risk-weighted amount of exposures
arising from leases with residual value risk (see Part IX of this section). Leases without any residual value risk will be accorded the same treatment as exposures collateralized by the underlying leased assets. (C) Securities Financing Transactions (SFTs) (section 202 of the BCR)
44. The calculation of the risk-weighted amount for SFTs depends on the economic
substance of the transaction and whether the transaction is booked in the banking book

MA(BS)3(IIIc) /P.14 (03/2025) or the trading book (see Part X of this section). (D) Credit-linked Notes (section 202A of the BCR)
45. The calculation of the risk-weighted amount for a credit-linked note depends on the
risk-weight attributable to the reference obligation or basket of reference obligations of the note, the note issuer, and the reporting AI’s maximum liability under the note (see Part XI of this section). (E) IPO financing (section 202B of the BCR)
46. A reporting AI may opt to apply section 64A of the BCR to its relevant corporate, bank
and retail exposures arising from IPO financing (pursuant to section 202B of the BCR). Under this option, the exposures arising from IPO financing eligible for 0% risk-weight should be reported as a separate portfolio type of the respective IRB subclass, by distinguishing such exposures from others as “IPO financing under BCR202B” in Divisions B and C. To attain a 0% risk-weight, the reporting AI should input a LGD of 0% and provide its own estimates or supervisory estimates for other credit risk components as appropriate. Note that this treatment is not applicable to any outstanding loan amounts after payments for allotted securities are made to the relevant receiving bank.
IV. Corporate, Sovereign and Bank Exposures
(A) Risk-weight Function for Derivation of Risk-weighted Amount
47. The calculation of the risk-weighted amount of a corporate, sovereign or bank exposure
is dependent on the estimates of PD, LGD, EAD and, in some cases, M, of a given exposure. (a) Non-defaulted exposures
48. Subject to paragraph 59, for corporate, sovereign and bank exposures that are not in
default, the risk-weighted amount is calculated by Formula 16 to section 156 of the BCR replicated as follows 8, 9 :
Correlation (R)
= 0.12 × (1 - EXP (-50 × PD)) / (1 - EXP (-50)) + 0.24 × [1 - (1 - EXP (-50 × PD)) / (1 - EXP (-50))] Maturity adjustment (b)

8 EXP denotes exponential and ln denotes the natural logarithm.
9 N(x) denotes the cumulative distribution function for a standard normal random variable (i.e. the probability that a normal random variable with mean 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 (i.e. the value of x such that N(x) = z). The normal cumulative distribution function and the inverse of the normal cumulative distribution function are, for example, available in Excel as the functions NORMSDIST and NORMSINV.

MA(BS)3(IIIc) /P.15 (03/2025)

49. According to section 156(4) of the BCR, a reporting AI should use the same risk-weight
function set out in paragraph 48 to calculate the risk-weighted amount of its corporate, sovereign and bank exposures which are in default (i.e. a default of the obligor in respect of the exposure has occurred by virtue of section 149(1) or (5A) of the BCR), except that the capital charge factor (K) for a defaulted corporate, sovereign or bank exposure should be equal to the greater of:
(i) zero; or
(ii) the figure resulting from the subtraction of the institution’s best estimate of the EL 11 from the LGD of the defaulted exposure. (c) SME corporates - Firm-size adjustment
50. For exposures to an SME corporate, a firm-size adjustment (i.e. 0.04 x (1 - (S-50) /
450)) according to section 157(1) of the BCR must be applied to the relevant risk￾weight function as set out in paragraph 48 for the calculation of the correlation:
Correlation (R)
= 0.12 × (1 - EXP (-50 × PD)) / (1 - EXP (-50)) + 0.24 × [1 - (1 - EXP (-50 × PD)) / (1 - EXP (-50))] - 0.04 × (1 - (S - 50) / 450) where S is expressed as the total annual sales of the SME corporate (or the consolidated total annual sales of the group of which the SME corporate is a member) in millions of HK$ with the value of S falling within the range from HK$50 million to HK$500 million. Total annual sales of less than HK$50 million will be deemed as equivalent to HK$50 million for the purpose of the firm-size adjustment. In the case where total annual sales do not accurately reflect a corporate’s scale of business, the MA may, on an exceptional basis, allow a reporting AI to substitute the corporate’s total assets for the total annual sales in calculating the firm-size adjustment for the SME corporate in

10 If this calculation results in a negative capital charge for any individual sovereign exposure, a reporting AI should apply a zero capital charge for that exposure. 11 With the prior consent of the MA, a reporting AI which uses the foundation IRB approach may use the supervisory estimate for the LGD as the EL for its corporate, sovereign and bank exposures which are in default in accordance with section 220(2)(c) of the BCR.

MA(BS)3(IIIc) /P.16 (03/2025) accordance with section 157(4) of the BCR. (d) Exposures to certain financial institutions – Correlation adjustment by way of asset value correlation multiplier
51. As stated in section 157A(1) and (2) of the BCR, for a reporting AI’s corporate,
sovereign or bank exposure to an obligor that is (i) a large regulated financial institution; or (ii) a financial institution that is not supervised by a financial regulator, the institution must multiply the correlation (R) in the risk weight function set out in paragraph 48 by 1.25.
52. To ensure that the information used for determining whether a financial institution is a
large regulated financial institution is timely and accurate, the reporting AI should obtain the total assets figures from the most recent audited financial statements of the financial institution or its wider group, as the case requires.
53. For the avoidance of doubt, if an SME corporate that is subject to the firm-size
adjustment mentioned in paragraph 50 is also a financial institution to which the asset value correlation multiplier requirements mentioned in paragraph 51 apply, a reporting AI should apply the adjustments mentioned in both paragraphs to the correlation (R) in the risk-weight function set out in paragraph 48 in accordance with section 157(5) of the BCR. (e) SL
54. The capital treatments set out in this subsection apply to all types of SL unless otherwise
specified.
55. Based on section 158(1) of the BCR, a reporting AI that meets the requirements for PD
estimation under the IRB approach for its SL should use the foundation IRB approach (or the advanced IRB approach, where the institution can also provide the estimates of other credit risk components) to calculate the risk-weighted amount for such SL, according to the relevant risk-weight functions set out in paragraphs 47 to 53.
56. The use of the foundation IRB approach or the advanced IRB approach by a reporting
AI in respect of its HVCRE exposures is subject to the additional requirements set out in section 158(1A), (1B) and (1C) of the BCR.
57. Subject to paragraph 56, a reporting AI may make a firm-size adjustment as described
in paragraph 50 to an HVCRE exposure that meets the size criteria for SME corporates.
58. In respect of SL under the supervisory slotting criteria approach, a reporting AI should
apply the risk-weight specified in Tables 18 and 18A and section 158(3) and (4) of the BCR for the relevant supervisory rating grade to which a SL is assigned in calculating the risk-weighted amount of that SL. (f) LSTs arising from derivative contracts and SFTs
59. A reporting AI may calculate the risk-weighted amount of the default risk exposure in
respect of LSTs by multiplying the EAD of the exposure by the relevant risk-weight

MA(BS)3(IIIc) /P.17 (03/2025) attributable to that exposure determined under the STC approach in accordance with
Part 4 of the BCR. However, the positions of such exposures should still be reported
in Form MA(BS)3(IIIc).
(B) Credit Risk Components
Probability of Default (PD)
60. For its corporate, sovereign and bank exposures, a reporting AI should rate on an
individual basis each legal entity to which the institution is exposed. In assigning a PD to individual obligors in a connected group, a reporting AI may assign the same obligor grade in respect of exposures to these obligors (such an obligor grade reflects the benefits of group support in accordance with the established policy of the institution and is thus likely to be more favourable than if the individual obligors were rated on a standalone basis), provided the requirements of section 154(d) of the BCR are met. A reporting AI is also required to set out in policies and put into operation a process for the identification of specific wrong-way risk for each legal entity to which the institution is exposed.
61. A reporting AI should follow the requirements set out in section 159 of the BCR to
determine the PD of its obligor grades, including- (i) For corporate and bank exposures, the PD of an exposure is the greater of the PD associated with the internal obligor grade to which that exposure is assigned, or 0.05%. (ii) For sovereign exposures, the PD of an exposure is the PD associated with the internal obligor grade to which that exposure is assigned (i.e. without any PD floor). (iii) For corporate, sovereign and bank exposures, the PD of an exposure assigned to a default grade (i.e. a default of the obligor in respect of the exposure has occurred by virtue of section 149(1) or (5A) of the BCR) is 100%. Loss Given Default (LGD)
62. A reporting AI should provide an estimate of the LGD for each corporate, sovereign
and bank exposure. There are two approaches for deriving this LGD estimate: the foundation IRB approach or the advanced IRB approach. LGD under foundation IRB approach
63. A reporting AI should follow the requirements set out in section 160 of the BCR to
determine the LGD applicable to its corporate, sovereign and bank exposures.

64. Except for the exposures specified in paragraph 66, a reporting AI using the advanced
IRB approach is allowed to use its own internal estimates of LGD for corporate and sovereign exposures subject to general requirements specified in section 161 of the BCR. The LGD should be measured as a percentage of the EAD.
65. The LGD estimated by a reporting AI must not be less than the LGD floor set out in
section 161(1)(ba) to (bd) of the BCR, where applicable 12
.
66. For a facility type that comprises default risk exposures in respect of single-name credit
default swaps that fall within the description in section 160(1)(c)(i) or (ii) of the BCR or transactions that fall within the description in section 160(1)(d)(i) and (ii) of the BCR, a reporting AI must comply with section 160(1)(c) or (d) of the BCR as if the institution were an institution that uses the foundation IRB approach. Exposure at Default (EAD)
67. The EAD of an exposure is measured without deduction of specific provisions and
partial write-offs.
68. The EAD applicable to a corporate exposure must be not less than the floor set out in
section 164(4A) and (4B) of the BCR.
69. In relation to an on-balance sheet exposure, in accordance with sections 163(1) and
164(1) and (4B) of the BCR, a reporting AI should use the current drawn amount of the exposure (for an exposure that is measured at fair value, the current drawn amount is the value determined in accordance with section 4A of the BCR), after taking into account the credit risk mitigating effect of any recognized netting, as an estimate of the EAD of the exposure such that the EAD of the exposure is not less than the sum of:
(i) the amount by which the institution’s CET1 capital would be reduced if the exposure were fully written-off; and (ii) any specific provisions and partial write-offs in respect of the exposure. Where the amount by which a reporting AI’s estimate of EAD in respect of an exposure

12 The LGD floor does not apply to the portion of a corporate exposure that is covered by a recognized guarantee issued by a sovereign (as per section 164(4C) of the BCR). Furthermore, the existence of the floor does not imply any waiver of the requirements of LGD estimation.

MA(BS)3(IIIc) /P.19 (03/2025) exceeds the sum of items (i) and (ii) of the exposure, this amount is termed a discount. The calculation of the risk-weighted amount should be independent of any discounts. In calculating the eligible provisions for the purpose of the EL-eligible provisions calculation as set out in Section C, any discounts attributed to defaulted exposures should be included.
70. In relation to the calculation of EAD of off-balance sheet exposures, a reporting AI
should refer to Part XII of this section.
Effective Maturity (M)
(a) M under foundation IRB approach
71. In accordance with section 167(1) of the BCR, for a reporting AI using the foundation
IRB approach for corporate, sovereign and bank exposures, M will be 2.5 years except for repo-style transactions where M will be 6 months 13 . (b) M under advanced IRB approach
72. A reporting AI using the advanced IRB approach for corporate and sovereign exposures
is required to calculate M for each exposure in accordance with section 168 of the BCR.
V. Retail Exposures
(A) Risk-weight Function for Derivation of Risk-weighted Amount
73. In line with section 176 of the BCR, there are three separate risk-weight functions for
retail exposures as set out in paragraphs 74 to 76. The risk-weights for retail exposures are based on separate assessments of PD and LGD as inputs to the risk-weight functions. The calculation of the risk-weighted amount for retail exposures does not require the input of M. (a) Non-defaulted exposures RM
74. For retail exposures which fall within the IRB subclass of RM to individuals or RM to
property-holding shell companies that are not in default (whether secured or partially secured 14), the risk-weighted amount is calculated by Formula 21 to section 176 of the BCR stipulated as follows:
Correlation (R) = 0.15

13 Subject to the fulfilment of the notification requirement under section 167(2) of the BCR, a reporting AI using the foundation IRB approach may calculate the M of all its corporate, sovereign and bank exposures in accordance with section 168 of the BCR. 14 This means that the risk-weight also applies to the unsecured portion of such RMs.

MA(BS)3(IIIc) /P.20 (03/2025)
Capital charge factor (K)

75. For retail exposures which fall within the IRB subclasses of QRRE (transactor) and
QRRE (revolver) that are not in default, the risk-weighted amount is calculated by Formula 22 to section 176 of the BCR stipulated as below:
Correlation (R) = 0.04
Capital charge factor (K)
= LGD × N[(1 - R)^-0.5 × G (PD) + (R / (1 - R))^0.5 × G (0.999)] - PD x LGD Risk-weight (RW) = K x 12.5 Risk-weighted amount = RW x EAD Small Business Retail Exposures and Other Retail Exposures to Individuals
76. For retail exposures which fall within the IRB subclasses of small business retail
exposures or other retail exposures to individuals that are not in default, the risk￾weighted amount is calculated by Formula 23 to section 176 of the BCR stipulated as below:
Correlation (R) 15
= 0.03 × (1 - EXP (-35 × PD)) / (1 - EXP (-35)) + 0.16 × [1 - (1 - EXP (-35 × PD)) / (1 - EXP (-35))] Capital charge factor (K) = LGD × N[(1 - R)^-0.5 × G (PD) + (R / (1 - R))^0.5 × G (0.999)] - PD x LGD Risk-weight (RW) = K x 12.5 Risk-weighted amount = RW x EAD (b) Defaulted exposures
77. Corresponding to section 176(5) of the BCR, a reporting AI should use the same risk￾weight function set out in paragraph 74, 75 or 76, as the case may be, to calculate the
risk-weighted amount of a retail exposure which is in default (i.e. a default of the obligor in respect of the exposure has occurred by virtue of section 149(1) or (5A) of the BCR), except that the capital charge factor (K) for a defaulted retail exposure should be equal to the greater of:

15 Correlation (R) is allowed to vary with PD.

(i) zero; or
(ii) the figure resulting from the subtraction of the institution’s best estimate of the EL from the LGD of the exposure. (B) Credit Risk Components Probability of Default (PD) and Loss Given Default (LGD)
78. For each pool of retail exposures, a reporting AI using the retail IRB approach should
provide an estimate of the PD and LGD associated with the pool. The PD for a retail exposure that is not defaulted is the long run average of one-year default rates for obligors which fall within the pool to which the estimate relates, subject to a floor of 0.1% (if it falls within the IRB subclass of QRRE (revolver)) or 0.05% (in any other cases) (per section 177(1)(b) and (ba) of the BCR). The PD of a retail exposure assigned to a pool of retail exposures in default is 100% (per section 177(1)(c) of the BCR).
79. The estimate of LGD of a retail exposure must not be less than the LGD floor set out
in section 178(c) to (ce) of the BCR, where applicable 16 .
Exposure at Default (EAD)
80. The EAD of an exposure is measured without deduction of specific provisions and
partial write-offs.
81. The EAD applicable to a retail exposure must not be less than the floor set out in section
164(4A) and (4B) of the BCR, with all necessary modifications, as per section 179 of the BCR.
82. In relation to an on-balance sheet exposure, a reporting AI should, according to sections
164(1) and (4B) of the BCR, use the current drawn amount of the exposure (for an exposure that is measured at fair value, the current drawn amount is the value determined in accordance with section 4A of the BCR), after taking into account the credit risk mitigating effect of any recognized netting, as an estimate of the EAD of the exposure such that the EAD of the exposure is not less than the sum of:
(i) the amount by which an institution’s CET1 capital would be reduced if the exposure were fully written-off; and (ii) any specific provisions and partial write-offs in respect of the exposure. Where the amount by which a reporting AI’s estimate of EAD in respect of an exposure exceeds the sum of items (i) and (ii) of the exposure, this amount is termed a discount.

16 The LGD floor does not apply to the portion of a retail exposure that is covered by a recognized guarantee issued by a sovereign (as per section 178(1)(d) of the BCR). Furthermore, the existence of the floor does not imply any waiver of the requirements of LGD estimation.

MA(BS)3(IIIc) /P.22 (03/2025)
The calculation of the risk-weighted amount should be independent of any discounts. In calculating the eligible provisions for the purpose of the EL-eligible provisions calculation as set out in Section C, any discounts attributed to defaulted exposures should be included.

83. In relation to the calculation of EAD of off-balance sheet exposures, a reporting AI
    should refer to Part XII of this section.
    VI. CIS Exposures
84. A reporting AI must determine the risk-weighted amount of a CIS exposure to a
    collective investment scheme not constituting a deductible holding in accordance with
    Part 6B of the BCR.
85. A reporting AI which uses the IRB approach to calculate the risk-weighted amount for
    its CIS exposure 17 should particularly note the specific capital treatments that apply to each individual circumstance by referring to the relevant sections in the BCR set out in the table below:

17 This refers to “IRB AI” in Part 6B of the BCR. A reporting AI which uses the IRB approach to calculate its credit risk for some of its non-securitization exposures but uses the STC approach to calculate the risk-weighted amounts of its CIS exposures is classified as an “exempted IRB AI” in Part 6B of the BCR. The capital treatment of CIS exposures for exempted IRB AIs is generally the same as that for STC AIs and exempted IRB AIs should report the return data of their CIS exposures in Form MA(BS)3(IIIb).

86. To avoid doubt,
(i) if a reporting AI’s CIS exposure to a Level 1 CIS or Level n+1 CIS (or any part of such CIS exposure) constitutes one or more than one deductible holding of the institution, such CIS exposure must continue to be subject to the requirements set out in Division 4 of Part 3 and section 183 of the BCR, where appropriate; and (ii) if a reporting AI that uses TPA to determine the risk-weighted amount of the underlying exposures of a Level 1 CIS has sufficient information that its CIS exposure to a Level 1 CIS (or any part of such CIS exposure) constitutes one or more than one deductible holding of the institution, such CIS exposure must continue to be subject to the requirements set out in Division 4 of Part 3 and
section 183 of the BCR, where appropriate.
87. A reporting AI may refer to Part IIIa and IIIb – Annex B for examples illustrating how
the risk-weighted amount of CIS exposures should be determined. Although risk￾weights under the STC approach are used in the examples for illustration, the calculation steps illustrated also apply to the IRB approach, except that the institution should determine the risk-weighted amount of its CIS exposure constituting deductible holdings and the amount of capital deduction in accordance with section 183 or Division 4 of Part 3 of the BCR.
VII. Other Exposures
(A) Cash Items
88. The risk-weighted amount of cash items is calculated by multiplying the EAD (i.e., the

MA(BS)3(IIIc) /P.24 (03/2025) principal amount) of each item by an applicable risk-weight as specified below:

of the BCR the amount of the payment made or the current market value of the thing delivered by the reporting AI, plus any positive current exposure associated with the transactions. However, if the EAD of a transaction is immaterial (i.e. less than HK$10 million), the reporting AI may choose to report such exposures under this item and apply a uniform 100% risk-weight to them in order to avoid performing a full credit assessment.
8. Amount due from transactions entered into on
a basis other than a DvP basis and which remain unsettled for 5 or more business days after the settlement date This item refers to any non-DvP transactions in securities, or transactions in foreign exchange and commodities, that have remained unsettled after the contractual date of payment or delivery to the reporting AI for 5 or more business days. The EAD of such transactions should be the amounts of payment made or the current market value of the thing delivered by the reporting AI, plus any positive current exposure associated with the transactions. 1250% Paragraph (j)
89. Unless otherwise specified in Part 6A of the BCR, cash items falling within items 5(b),

Certified Public Accountants where the asset leased is a tangible asset. Other interests in land which are not occupied or used in the operation of the reporting AI’s business should also be reported here.
2. Exposures subject to the IRB approach which are not
elsewhere specified
This item includes exposures that are not classified under the IRB class of corporate, sovereign, bank, retail or CIS exposures or the IRB subclass of cash items. 100% unless otherwise specified by the MA
VIII. Purchased Receivables
(A) Derivation of Risk-weighted Amount for Default Risk
91. In accordance with section 197(1) of the BCR, purchased receivables should be
classified as retail or corporate exposures, according to the nature of the receivables. For receivables belonging unambiguously to one IRB subclass, the risk-weight for default risk is based on the risk-weight function applicable to that particular IRB subclass, as long as the reporting AI can meet the relevant requirements for the use of that particular risk-weight function. For example, if a reporting AI cannot comply with the criteria for QRRE (revolver), the institution should use the risk-weight function for other retail exposures to individuals. Where a reporting AI purchases a hybrid pool of receivables containing a mixture of exposures, the institution should, if it cannot separate the receivables into different IRB subclasses, apply the risk-weight function that will result in the highest risk-weighted amount of the exposures in the pool of purchased receivables. (a) Purchased retail receivables
92. A reporting AI may use the “top-down” approach for its purchased retail receivables as
for other retail exposures (i.e. estimation of credit risk components on a pooled basis) set out in section 198(3) of the BCR, provided that the institution meets the relevant requirements for retail exposures as set out in the BCR, and, in the case of calculation of default risk, it meets the requirements referred to in section 200(d) of the BCR. The reporting AI may utilize external and internal reference data to estimate the PD and LGD in respect of its purchased retail receivables at the pool level (i.e. the institution is not required to estimate PDs and LGDs or EL for individual retail receivables within the pool). The estimates for PD and LGD (or EL) should be calculated for the purchased retail receivables on a stand-alone basis, that is, without regard to any recourse to, or guarantees from, the seller or other parties. (b) Purchased corporate receivables
93. A reporting AI which purchases corporate receivables should use the “bottom-up”

MA(BS)3(IIIc) /P.28 (03/2025) approach to estimate the credit risk components for individual receivables for the calculation of the risk-weighted amount (i.e. consistent with the treatment of the institution’s corporate exposures) set out in section 198(2) of the BCR. In other words, the reporting AI is not allowed to use the “top-down” approach to its purchased corporate receivables. The estimates for PD and LGD (or EL) should be calculated for each of the purchased corporate receivables on a stand-alone basis, that is, without regard to any recourse to, or guarantees from, the seller or other parties. (B) Derivation of Risk-weighted Amount for Dilution Risk
94. Dilution refers to the possibility that the amount of a receivable is reduced through cash
or non-cash credits to the receivable’s obligor 18 . A reporting AI must follow the requirements set out in section 199 of the BCR to calculate the risk-weighted amount for dilution risk.
IX. Leasing Transactions
(A) Leases without Residual Value Risk
95. In accordance with section 201(1) of the BCR, exposures arising from leasing
arrangements, other than those exposing the reporting AI to residual value risk (see paragraph 96), should be treated as exposures secured by the leased assets. A reporting AI may recognize the credit risk mitigating effect of the leased assets as recognized collateral if the relevant requirements set out in the BCR are met. (B) Leases with Residual Value Risk
96. Exposures arising from leasing arrangements that expose the reporting AI to residual
value risk should be treated in accordance with section 201(2) of the BCR as follows:
(i) risk-weighted amount for default risk – a reporting AI should calculate the risk￾weighted amount for default risk in respect of the exposure by multiplying the discounted lease payment stream (i.e. EAD) by a risk-weight derived by using the risk-weight function applicable to the IRB subclass within which an exposure to the lessee falls (the PD and LGD as those which the institution assigns to the exposure); and (ii) risk-weighted amount for residual value risk – a reporting AI should calculate the risk-weighted amount for residual value risk in respect of the exposure by multiplying the residual value of the leased asset by a risk-weight of 100%.
X. Securities Financing Transactions

18 Examples include offsets or allowances arising from returns of goods sold, disputes regarding product quality, possible debts of the borrower to a receivable’s obligor, and any payment or promotional discounts offered by the borrower (e.g. a credit for cash payments within 30 days).

MA(BS)3(IIIc) /P.29 (03/2025)
97. If the securities underlying the SFTs are securitization issues, the reporting AI should
determine the risk-weight attributable to the securities in accordance with Part 7 of the BCR and report the securities in Form MA(BS)3(IIId) accordingly.
98. Subject to paragraph 99, the default risk exposures in respect of SFTs (including
centrally cleared trades that are treated as bilateral trades) booked in the banking book or trading book of reporting AIs and the associated risk-weighted amount are determined in the following manner:
(i) institutions with the MA’s approval to use the IMM(CCR) approach to calculate the default risk exposures in respect of SFTs (and also any LST arising from those transactions where covered by the IMM(CCR) approval) should report the exposures in Form IRB_OBSD_IMM. The instructions set out in paragraphs 121 to 124 on the use of the IMM(CCR) approach in respect of derivative contracts apply to SFTs (see also section 202(2) of the BCR); (ii) institutions that do not have an IMM(CCR) approval to calculate the default risk exposures in respect of SFTs should calculate the exposures in accordance with Division 2B of Part 6A of the BCR and report the exposures in Form IRB_OBSD_SFT_N_IMM (see also section 202(1) and (3) of the BCR).
99. Subject to paragraph 100, where a reporting AI applies Division 2 or 2B of Part 6A of
the BCR, as the case requires, to an SFT, the institution must determine the risk-weight to be allocated to its exposure under the SFT in accordance with section 202(6) of the BCR.
100. For LSTs arising from SFTs, a reporting AI may determine the relevant risk-weight
using the STC approach on a permanent basis.
101. The SFT risk-weighted amount of a reporting AI referred to in paragraph 30(iii) is the
sum of the default risk risk-weighted amounts for all counterparties to the SFTs of the institution where the default risk risk-weighted amount for each of the counterparties is calculated as the sum of the risk-weighted amounts of the default risk exposures across all the SFTs with the counterparty calculated in accordance with section 202 of the BCR.
XI. Credit-linked Notes (CLNs)
102. A CLN held by the reporting AI should be allocated a risk-weight, as determined by
the applicable risk-weight function, which is the higher of the risk-weight attributable to the reference obligation(s) of the note as if the institution had a direct exposure to the reference obligation(s), or the risk-weight attributable to the note as set out in section 202A(1) of the BCR. However, a reporting AI is not required to provide regulatory capital for its exposure to a CLN held by it in excess of the institution’s maximum liability under the note according to section 202A(2) of the BCR.
XII. Calculation of Risk-weighted Amount of Off-balance Sheet Exposures

MA(BS)3(IIIc) /P.30 (03/2025)
(A) Classification of Off-balance Sheet Exposures
103. A reporting AI is required to categorize its off-balance sheet exposures into one of the
following two types:
(i) off-balance sheet exposures (other than default risk exposures in respect of derivative contracts and SFTs) in the banking book; (ii) default risk exposures in respect of derivative contracts and SFTs in both the banking book and trading book. (B) Derivation of Risk-weighted Amount of Off-balance Sheet Exposures
104. Except as specified in paragraphs 106 and 107, for the calculation of the risk-weighted
amount of off-balance sheet exposures, a reporting AI should:
(i) convert an off-balance sheet exposure into credit equivalent amount (i.e. EAD) by:
 applying an applicable credit conversion factor (CCF) to the principal amount of the off-balance sheet exposure (other than derivative contracts and SFTs) in the banking book; and  using the IMM(CCR) approach, the SA-CCR approach or the methods referred to in section 10A(1)(b) of the BCR, as permitted under the BCR, in respect of the derivative contract and SFT, as the case may be (the resultant EAD estimate is termed “default risk exposure”); and (ii) multiply the credit equivalent amount of the off-balance sheet exposure by an applicable risk-weight.
105. Regarding default risk exposure, this Part mainly illustrates the capital treatments of
those derivative contracts using the IMM(CCR) approach or the SA-CCR approach. For specific instructions regarding default risk exposures with respect to SFTs, the reporting AI should refer to paragraph 98(i) for those that are subject to the IMM(CCR) approach, and paragraph 98(ii) for those that are not.
106. For LSTs arising from derivative contracts or SFTs, a reporting AI may determine the
relevant risk-weight using the STC approach on a permanent basis.
107. If a reporting AI issues a CLN to cover a default risk exposure, the amount of the
proceeds received from the issuance of the CLN should not be included in the calculation of the amount of the default risk exposure under Division 1A, 2 or 2B of
Part 6A of the BCR.
108. Under the SA-CCR approach and the IMM(CCR) approach, the default risk exposures
of credit derivative contracts falling within the following categories can be regarded as zero:

MA(BS)3(IIIc) /P.31 (03/2025)
(i) credit default swaps that have been reported as “direct credit substitutes” in item 1 of Division D (i.e. the reporting AI has already held capital against the credit risk of the reference obligations underlying the swaps); (ii) recognized credit derivative contracts held by the reporting AI as protection buyer in respect of which the credit risk mitigation effects have already been taken into account in accordance with Division 10 of Part 6 of the BCR for the purposes of risk-weighted amount calculation. Off-balance Sheet Exposures (Other than Default Risk Exposures in respect of Derivative Contracts and SFTs) (a) CCFs and EAD
109. A reporting AI using the foundation IRB approach should classify each of its off￾balance sheet exposures (other than default risk exposures) in the banking book as one
of the items and apply the CCF listed in Table 20 under section 163(2) and (2AA) of the BCR.
110. A reporting AI using the advanced IRB approach for corporate and sovereign exposures
or the retail IRB approach for retail exposures is allowed to provide its own estimates of CCFs for off-balance sheet exposures only if the exposures are revolving in nature and not subject to a CCF of 100% in accordance with section 164(3)(a) and (3A). Otherwise, the reporting AI must apply the CCF listed in Table 20 under section 163(2) and (2AA) of the BCR to determine the EAD of such exposures.
111. For off-balance sheet exposures arising from unsegregated collateral posted to the
counterparty by a reporting AI, the institution using the foundation IRB approach should refer to section 163(2A) and (2B) of the BCR to estimate the EAD of the exposures, while the institution using the advanced IRB approach should refer to
section 164(2)(b), (4) and (4A) of the BCR to estimate the EAD of the exposures.
112. For corporate, sovereign and bank exposures, the principal amount to which the CCF
is applied is the lower of:
(i) the amount of the unused committed credit line; or (ii) the amount that reflects any possible constraining availability of the facility (e.g. the existence of a ceiling on the potential lending amount subject to the borrower’s reported cash flow). If the facility is constrained in this manner, the reporting AI should have sufficient monitoring and management procedures to support this treatment.
113. For retail exposures with an uncertain future drawdown (e.g. credit cards), a reporting
AI should take into account the drawdown and repayment history and the expectation of additional drawings by the obligors prior to default in its overall calibration of loss estimates. In particular, where a reporting AI does not reflect CCFs for undrawn lines in its EAD estimates, it should reflect in its LGD estimates the likelihood of additional drawings prior to default. Conversely, if an institution does not incorporate the

MA(BS)3(IIIc) /P.32 (03/2025) possibility of additional drawings in its LGD estimates, it should do so in its EAD estimates.
114. When only the drawn balances of retail facilities have been securitized, a reporting AI
should ensure that it continues to hold required capital against the undrawn balances associated with the securitization exposures under the IRB approach for commitment. (b) Calculation of risk-weighted amount
115. In calculating the risk-weighted amount of off-balance sheet exposures (other than
default risk exposures) in the banking book, the applicable risk-weight to an exposure should be derived from the risk-weight function for the IRB class/subclass within which the exposure falls. Default Risk Exposures in respect of Derivative Contracts (including centrally cleared trades that are treated as bilateral trades) using SA-CCR approach (a) Calculation of EAD
116. A reporting AI using the foundation IRB approach or the advanced IRB approach must
determine the outstanding default risk exposures in respect of its derivative contracts booked in the banking book or trading book of the institution based on the default risk exposures calculated for the contracts by using the SA-CCR approach in accordance with Division 1A of Part 6A of the BCR.
117. The default risk exposure in respect of a derivative contract should be adjusted for the
credit risk mitigating effect of any recognized netting.
118. Where a reporting AI enters into no less than one derivative contract with a
counterparty, the applicable default risk exposure in respect of the transactions and contracts with that counterparty (the outstanding default risk exposure) is the greater of:
(i) zero; or
(ii) the difference between –
(A) the sum of the amounts of the default risk exposures across all netting sets with the counterparty; and (B) the CVA loss in respect of that counterparty. (b) Calculation of risk-weighted amount
119. The SA-CCR risk-weighted amount in respect of derivative contracts of a reporting AI
is the sum of the default risk risk-weighted amounts for all the counterparties to the contracts where the default risk risk-weighted amount for each of the counterparties is calculated as the product of:
(i) the outstanding default risk exposure to the counterparty as calculated under paragraph 118; and

MA(BS)3(IIIc) /P.33 (03/2025)
(ii) the applicable risk-weight to the exposure derived from the risk-weight function for the IRB class/subclass within which the counterparty of the exposure falls.
120. For the calculation of the risk-weighted amount for LSTs arising from derivative
contracts, a reporting AI may determine the relevant risk-weight using the STC approach on a permanent basis. Default risk exposures in respect of derivative contracts and SFTs (including centrally cleared trades that are treated as bilateral trades) under the IMM(CCR) approach (a) Calculation of EAD and risk-weighted amount
121. A reporting AI may use the IMM(CCR) approach to calculate the default risk exposures
in respect of bilateral trades (including centrally cleared trades that are treated as bilateral trades) arising from derivative contracts and SFTs (including any LST arising from those transactions or contracts) if it has an IMM(CCR) approval for those transactions, contracts or LSTs, as the case may be.
122. A reporting AI must calculate -
(i) the portfolio-level risk-weighted amount of the relevant exposures based on current market data in accordance with sections 226D(1)(a) and (2)(a) of the BCR; and (ii) the portfolio-level risk-weighted amount of the relevant exposures based on stress calibration in accordance with sections 226D(1)(b), (2)(b) and (3) of the BCR.
123. For the calculation of the risk-weighted amounts referred to in paragraph 122(i) and (ii)
in respect of LSTs arising from derivative contracts and SFTs, a reporting AI may determine the relevant risk-weight using the STC approach on a permanent basis.
124. The higher of the portfolio-level risk-weighted amount calculated under paragraph
122(i) and (ii) is the IMM(CCR) risk-weighted amount in respect of the derivative contracts and SFTs of the reporting AI that are covered by its IMM(CCR) approval. Accordingly, the default risk exposures of the derivative contracts and SFTs to be reported in Form IRB_OBSD_IMM are those calculated in accordance with sections 226E to 226M of the BCR that give rise to the IMM(CCR) risk-weighted amount (i.e. the higher of the number calculated under paragraph 122(i) and (ii)).
XIII. Credit Risk Mitigation
125. Subject to section 203(1A), (1B) and (2) of the BCR, a reporting AI may take into
account the effect of recognized credit risk mitigation in its calculation of risk-weighted amount of exposures in accordance with Division 10 of Part 6 of the BCR, including:

MA(BS)3(IIIc) /P.34 (03/2025)
(i) recognized collateral (sections 139, 204 to 208 of the BCR); (ii) recognized netting (section 209 of the BCR); and (iii) recognized guarantees and recognized credit derivative contracts (sections 210 to 219 of the BCR). (A) Capital Treatment of Recognized Collateral
126. Under the IRB approach, collateral is recognized through the determination of LGD for
corporate, sovereign, bank and retail exposures in accordance with section 204 of the BCR. The details of the different types of recognized collateral under the foundation IRB approach and the advanced IRB / retail IRB approach are stipulated in sections 139, 204 to 208 of the BCR. (B) Capital Treatment of Recognized Netting
127. If a reporting AI is entitled pursuant to a valid bilateral netting agreement or valid cross￾product netting agreement to net amounts owed by the institution to a counterparty
against amounts owed by the counterparty to the institution, the institution may take into account the credit risk mitigating effect of the recognized netting in calculating the EAD of its exposure to the counterparty in accordance with section 209 of the BCR.
128. In respect of on-balance sheet netting for sovereign exposures, the market makers who
have short positions in Exchange Fund Bills/Notes may report their net holdings of such

MA(BS)3(IIIc) /P.35 (03/2025) instruments provided that the short positions are covered by the Sale and Repurchase Agreements with the HKMA. The following steps should be taken in determining the amount to be reported:
(i) the long and short positions of instruments with a residual maturity of less than one year may be offset with each other; (ii) the long and short positions of instruments with a residual maturity of not less than one year may be offset with each other; (iii) if the net positions of both items (i) and (ii) above are long, the positions should be reported; and (iv) if the net position in item (i) is long and the net position in item (ii) is short, or the other way round, the positions can be netted with each other on a dollar for dollar basis. The resultant net long position, if any, should be reported. (C) Capital Treatment of Recognized Guarantees and Recognized Credit Derivative Contracts
129. Under the IRB approach, a reporting AI may use the substitution framework to take
into account the credit risk mitigating effects of recognized guarantees and recognized credit derivative contracts in calculating the risk-weighted amount of an exposure in accordance with the BCR provisions set out in the following table:
Exposures BCR reference
(i) Corporate, sovereign and bank exposures under the foundation IRB approach Sections 210, 211, 213, 214, 215 and 216 (ii) Corporate and sovereign exposures under the advanced IRB approach Sections 210, 212, 213, 214, 215 and 217 (iii) Retail exposures under the retail IRB approach (iv) Purchased receivables Sections 210 and 219 Specifically, if a recognized guarantee is provided to a reporting AI or a recognized credit derivative contract is entered into by the institution, and the institution uses the foundation IRB approach to calculate its credit risk for corporate or sovereign exposures to the guarantor or counterparty (where applicable), the institution should allocate to the covered portion of an underlying exposure a relevant risk-weight attributable to that portion of the underlying exposure determined using the foundation IRB approach according to section 217(1A), (1B) and (3A) of the BCR. In the case of an uncovered portion of an underlying exposure, a reporting AI must allocate risk-weight calculated of the underlying exposure (e.g. advanced IRB approach) in accordance with section 217(6) of the BCR.
130. For the substitution framework under the foundation IRB approach, a reporting AI must
adjust the amount of the credit protection in accordance with section 216(5) and (6) if

MA(BS)3(IIIc) /P.36 (03/2025) there is a currency mismatch or maturity mismatch between an underlying exposure of the institution and a recognized guarantee or recognized credit derivative contract covering the underlying exposure.
131. Pursuant to section 213(1) of the BCR, an internal risk transfer used by a reporting AI
to transfer the credit risk of one or more credit exposures booked in the institution’s banking book to its trading book may be recognized for the purposes of calculating the risk-weighted amount of the protected credit exposure if there is an external hedge that meets all the conditions specified in section 213(2) of the BCR.
132. Where a reporting AI issues a CLN to cover the credit risk of an underlying exposure
(i.e. the AI buys credit protection), the maximum amount of protection is the amount of the funds received from issuing that note. The protected amount should be treated as an exposure collateralized by cash deposits while the remaining unprotected amount, if any, should be treated as an exposure to the issuer of the underlying asset.

MA(BS)3(IIIc) /P.37 (03/2025)
Section C: Treatment of Expected Losses and Eligible Provisions under IRB Approach
I. Determination of Total EL Amount
133. A reporting AI should sum the EL amount (i.e. EL x EAD) attributed to its corporate,
sovereign, bank and retail exposures that are subject to the IRB approach to obtain a total EL amount. Please refer to section 220 of the BCR for details.
134. To determine EL, a reporting AI should follow the requirements set out in
(i) section 220(2) of the BCR for exposure other than SL under supervisory slotting criteria approach, and (ii) section 220(3) to (5) of the BCR for SL that are under the supervisory slotting criteria approach.
II. Determination of Total Eligible Provisions
135. “Total eligible provisions” is defined as the sum of eligible provisions that are attributed
to corporate, sovereign, bank and retail exposures that are subject to the IRB approach, where eligible provisions means the sum of the reporting AI’s specific provisions, partial write-offs, regulatory reserve for general banking risks and collective provisions attributed to non-securitization exposures that are subject to the IRB approach and any discounts referred to in paragraphs 69 and 82 on the aforesaid IRB exposures that are in default (see section 139(1) of the BCR). (A) A Portion of Exposures subject to STC Approach to Credit Risk
136. A reporting AI using only the IRB approach, or both the IRB approach and the STC
approach, to calculate its credit risk for non-securitization exposures, either on a transitional basis, or on a permanent basis if the exposures subject to the STC approach are exempted from the IRB approach, should determine the portion of regulatory reserve for general banking risks and collective provisions that is attributed to exposures under the STC approach, IRB approach, securitization internal ratings-based approach (SEC-IRBA), securitization external ratings-based approach (SEC-ERBA), securitization standardized approach (SEC-SA) and securitization fall-back approach (SEC-FBA). The treatment of such reserves and provisions attributed to exposures under these approaches is set out in the completion instructions of Form MA(BS)3(II) (see paragraphs 99 and 100), with elaborations on apportionment method in paragraphs 137 and 138.
137. A reporting AI should attribute its total regulatory reserve for general banking risks and
collective provisions on a pro rata basis according to the proportion of the risk-weighted amount calculated by using the STC approach, IRB approach, SEC-IRBA, SEC-ERBA, SEC-SA or SEC-FBA, as the case requires (which does not include exposures to CCPs calculated under Part 6A of the BCR). However, with the prior consent of the MA under
section 42(2)(b) of the BCR, a reporting AI may use its own method to apportion its
total regulatory reserve for general banking risks and collective provisions among the various credit risk calculation approaches. For example, when one approach to determining the risk-weighted amount (e.g. STC approach or IRB approach) is used exclusively within an entity of the reporting AI’s consolidation group, the regulatory

MA(BS)3(IIIc) /P.38 (03/2025) reserve for general banking risks and collective provisions booked within the entity using the STC approach may be attributed to exposures under the STC approach. Similarly, the regulatory reserve for general banking risks and collective provisions booked within an entity using the IRB approach may be attributed to the total eligible provisions.
138. The MA may, on a case-by-case basis, consider whether there are particular
circumstances that justify a reporting AI using its internal allocation methodology for allocating the reserves for general banking risks and collective provisions for recognition in capital under the STC approach, IRB approach, SEC-IRBA, SEC-ERBA, SEC-SA and SEC-FBA. The reporting AI should obtain the MA’s prior consent before such a method can be used.
III. Treatment of Total EL Amount and Total Eligible Provisions
139. A reporting AI using the IRB approach should compare the amount of total eligible
provisions with the total EL amount in accordance with section 220(1) of the BCR.
140. Where the total EL amount exceeds the total eligible provisions, the reporting AI should
deduct the difference from its CET1 capital, in accordance with section 43(1)(i) of the BCR.
141. Where the total EL amount is less than the total eligible provisions, the reporting AI
may include the difference in its Tier 2 capital, up to a maximum of 0.6% of the risk￾weighted amount (excluding securitization exposures) calculated under the IRB approach (which does not include exposures to CCPs calculated under Part 6A of the BCR).

MA(BS)3(IIIc) /P.40 (03/2025) approach which should be reported in Form IRB_SLSLOT 19). In each reporting Form, a reporting AI should state whether the foundation IRB approach or advanced IRB approach is used, the IRB class and subclass for which the Form is completed, and the portfolio type when more than one Form is reported for an IRB subclass. Item Nature of item Columns (1) & (2) Obligor grade A reporting AI using the IRB approach is required to have a minimum of seven grades for non-defaulted obligors and one for defaulted obligors in its rating systems. The reporting AI can insert additional grades into column (1) if its internal obligor grades are more than eight. Under column (2), enter “N” for a non-defaulted obligor grade and “D” for a defaulted obligor grade. The obligor grades should be presented in an ascending order of their associated average PD. For consistency purposes, a reporting AI should report every obligor grade within its rating systems in each Form even though there is no exposure falling within a particular obligor grade. Columns (3), (4) & (5) PD range A reporting AI should report a distribution of PD bands as is currently used for internal purposes. For each obligor grade, report the average PD (in percentage) under column (5). This estimate will be used for calculation of the risk-weighted amount for each exposure. The average PD for corporate, sovereign and bank exposures that are not in default is the PD associated with the internal obligor grade to which that exposure is assigned, with a PD floor for corporate and bank exposures of 0.05%. For defaulted exposures, report 100% as the average PD for corporate, sovereign and bank exposures. Report the lower bound and upper bound of the PD band for each obligor grade under columns (3) and (4) respectively. The average PD must lie between the lower and upper boundaries except for the otherwise caused by the PD floor mentioned above. Where a reporting AI uses a single PD estimate for each obligor grade (i.e. no PD range), the institution should enter the same PD estimate as the upper and lower bounds of the range (i.e. the same PD estimates for all columns (3), (4) and (5)). In cases where a reporting AI calculates its risk-weighted amount for both default risk and dilution risk of its purchased corporate receivables, only the PD estimate for default risk should be reported. Columns (6) to (11) EAD calculation For each obligor grade, give a breakdown of the exposures before recognized guarantees/credit derivative contracts by:

19 To avoid doubt, this means that a reporting AI should capture its SL under the foundation IRB approach or advanced IRB approach in Form IRB_CSB, and those under the supervisory slotting criteria approach in Form IRB_SLSLOT.

(i) Example 1 (Corporate exposure with on-balance sheet netting) Corporate A, classified as grade 5 under the Bank XYZ’s internal rating system, borrowed a senior (i.e. not subordinated) loan of HK$100 Mn from Bank XYZ. Corporate A has also placed a pledged deposit of HK$10 Mn with Bank XYZ. Both the loan and the pledged deposit are subject to a valid bilateral netting agreement. Given:
 Corporate A’s group total annual sales = HK$500 Mn or more  Specific provision = HK$1 Mn  No currency and maturity mismatch between the loan and the pledged deposit Workings:
 Estimated PD (grade 5) for Corporate A = 3%  LGD = 40%  RW = 114.17%  M = 2.5 years (a) Exposures before recognized guarantees/credit derivative contracts:
(1) On-balance sheet exposures before netting = HK$100 Mn (2) On-balance sheet exposures after netting = max [0, exposures - liabilities x (1 - Hfx)] = HK$100 Mn - HK$10 Mn = HK$90 Mn (b) Exposures after recognized guarantees/credit derivative contracts (on-balance sheet exposures after netting) = HK$90 Mn (i.e. EAD) (c) Risk-weighted amount of the exposure to Corporate A = EAD x RW = HK$90 Mn x 1.1417 = HK$102.753 Mn (d) EL-eligible provisions calculation:
(1) EL amount
= EAD x PD x LGD
= HK$90 Mn x 0.03 x 0.40
= HK$1.08 Mn
(2) Eligible provisions = HK$1 Mn

Corporate B:
 Estimated PD (grade 5) for Corporate B = 3%  LGD of the uncovered portion = 75%  RW = 162.63%  M = 2.5 years (a) Exposures before recognized guarantees/credit derivative contracts (on-balance sheet exposures before/after netting) = HK$100 Mn (b) Exposures after recognized guarantees/credit derivative contracts (on-balance sheet exposures after netting) = HK$100 - HK$40 Mn = HK$60 Mn (i.e. EAD) (c) Risk-weighted amount for the exposure to Corporate B (i.e. portion not covered by the guarantee issued by Bank C) = EAD x RW = HK$60 Mn x 1.6263 = HK$97.578 Mn (d) EL-eligible provisions calculation:
(1) EL amount
= EAD x PD x LGD
= HK$60 Mn x 0.03 x 0.75

(2) Eligible provisions

(1) EL amount
= EAD x PD x LGD
= HK$40 Mn x 0.0025 x 0.45
= HK$0.045 Mn
(2) Eligible provisions
= HK$1.72 Mn x 40/100 (or a risk-weighted basis, such as based on the EL amount i.e. 0.045/(1.35 + 0.045)) = HK$0.688 Mn (iii) Example 3 (Secured corporate exposure fully guaranteed by a sovereign) Corporate D, classified as grade 5 under the Bank XYZ’s internal rating system, borrowed a senior loan of HK$100 Mn from Bank XYZ. The transaction is secured by a BBB rated six-year corporate bond of HK$40 Mn and another recognized IRB collateral of HK50 Mn. Also, the exposure is fully guaranteed by Central Bank E which is classified as grade 4 under the Bank XYZ’s internal rating system. Given:
 Corporate D’s group total annual revenue = HK$500 Mn or more  Haircut for the BBB rated six-year corporate bond (i.e. credit quality grade 3 of residual maturity >5 years) = 12%  Haircut for recognized IRB collateral = 40%  No currency and maturity mismatch between the transaction and the collateral/guarantee  No specific provisions made Workings:
Corporate D:
 Estimated PD (grade 5) for Corporate D = 3%  M = 2.5 years

 Specific provisions = HK$40 Mn
 Best estimate of EL = 35%
Workings:
 Estimated PD (grade 8) for Corporate F = 100%  LGD = 40% (a) Exposures before/after recognized guarantees/credit derivative contracts (on￾balance sheet exposures before/after netting) = HK$100 Mn (i.e. EAD) (b) Risk-weighted amount of the exposure to Corporate F = max [0, LGD - EL] x 12.5 x EAD = (40% - 35%) x 12.5 x HK$100 Mn = HK$62.5 Mn (c) EL-eligible provisions calculation:

1. The above table provides illustrative risk-weights for UL calculated for the IRB class of corporate
   exposures and the IRB subclasses of retail exposures under the IRB approach. Each set of risk￾weights is produced using the appropriate risk-weight functions. The inputs used to calculate the illustrative risk weights include measures of PD and LGD and an assumed M of 2.5 years.
2. A firm-size adjustment applies to exposures falling within the IRB subclass of small-and-medium
   sized corporates (defined as exposures to a corporate where the reported total annual sales for the consolidated group of which the corporate is a part is less than HK$500 million). Accordingly, the firm-size adjustment is made in determining the second set of risk-weights provided in the second column of corporate exposures given that the annual sales of the corporate receiving the exposure is assumed to be HK$50 million.

Return of Capital Adequacy Ratio
Part IIId – Risk-weighted Amount for Credit Risk
(Securitization Exposures)
Form MA(BS)3(IIId)
Introduction

1. Form MA(BS)3(IIId) of Part III should be completed by each authorized
   institution (“AI”) incorporated in Hong Kong that has securitization exposures 1 booked in its banking book.
2. This Form contains the following Divisions:
   (a) Division A is a summary table showing the total risk-weighted amounts (“RWAs”) of the securitization exposures of a reporting AI and the capital deduction required in respect of its securitization transactions or securitization exposures; (b) Division B captures securitization exposures (other than re-securitization exposures) that are subject to the securitization internal ratings-based approach (SEC-IRBA); (c) Division C1 captures securitization exposures (other than re-securitization exposures) that are subject to the securitization external ratings-based approach (SEC-ERBA) where the risk-weights are determined based on— (i) long-term ECAI issue specific ratings or long-term inferred ratings; or (ii) (if the reporting AI has an IAA approval to use the internal assessment approach (IAA)) internal credit ratings mapped to equivalent long￾term ECAI issue specific ratings; (d) Division C2 captures securitization exposures (other than re-securitization exposures) that are subject to the SEC-ERBA where the risk-weights are determined based on— (i) short-term ECAI issue specific ratings or short-term inferred ratings; or

1 For example, asset-backed securities, mortgage-backed securities, credit enhancements, liquidity facilities, interest rate or currency swaps, credit derivative contracts, tranched credit protection, and reserve accounts, such as cash collateral accounts, recorded as an asset by the originating institution.

MA(BS)3(IIId)/P.2 (03/2025)
(ii) (if the reporting AI has an IAA approval to use the IAA) internal credit ratings mapped to equivalent short-term ECAI issue specific ratings; (e) Division D1 captures securitization exposures (other than re-securitization exposures) that are subject to the securitization standardized approach (SEC-SA); (f) Division D2 captures re-securitization exposures that are subject to the SEC￾SA; and (g) Division E captures securitization exposures (including re-securitization exposures) that are subject to the securitization fall-back approach (SEC￾FBA).
3. In each of Divisions B, D1, D2 and E, columns (1) to (3) are for reporting of on￾balance sheet securitization exposures while columns (4) to (7) are for reporting
of off-balance sheet securitization exposures. In Divisions C1 and C2, on￾balance sheet securitization exposures and off-balance sheet securitization exposures must be reported in columns (1) to (3a) and columns (4) to (7a) respectively. Columns (3a) and (7a) are subsets of columns (3) and (7).
4. This Form and its completion instructions should be read in conjunction with the
Banking (Capital) Rules (“BCR”) and the relevant supervisory policy/guidance related to the capital adequacy framework (in particular, the SPM module CR￾G-12 “Credit Risk Transfer Activities” (to the extent related to credit assessments and significant credit risk transfer) and the Q&As on the securitization framework).
Section A: Definitions and General Instructions
In this Form—
5. “Exposure Amount before CRM” means the exposure amount of a securitization
exposure before taking into account any Part 7 credit risk mitigation (“Part 7 CRM”) obtained for the exposure, but net of any amounts that are permitted to be deducted from the exposure amount (e.g. specific provisions, write-offs and non-refundable purchase price discounts) under section 236(3) of the BCR.
6. “Principal Amount” of an off-balance sheet exposure has the meaning given by
paragraph (b) of the definition of principal amount in section 227(1) of the BCR. However, if the off-balance sheet exposure concerned is a default risk exposure arising from a derivative contract, “Principal Amount” means the nominal notional amount of the contract, which should not be confused with any effective notional amount or adjusted notional calculated for the contract under Part 6A of the BCR.
7. “Senior exposures” means securitization exposures in senior tranches (See
Annex IIId-A for more information on the determination of seniority).
8. “Non-senior exposures” means securitization exposures in non-senior tranches.

MA(BS)3(IIId)/P.3 (03/2025)
9. “Senior long-term securitization exposures” means senior exposures that have a
long-term ECAI issue specific rating or a long-term inferred rating.
10. “Non-senior long-term securitization exposures” means non-senior exposures
that have a long-term ECAI issue specific rating or a long-term inferred rating.
11. “Senior short-term securitization exposures” means senior exposures that have a
short-term ECAI issue specific rating or a short-term inferred rating.
12. “Non-senior short-term securitization exposures” means non-senior exposures
that have a short-term ECAI issue specific rating or a short-term inferred rating.
13. “Risk-weight” means—
(a) in the case of a securitization exposure (other than an NPL securitization exposure or a re-securitization exposure)—the risk-weight applicable to the exposure determined by using the SEC-IRBA, SEC-ERBA, SEC-SA or SEC-FBA— (i) after taking into account the risk-weight floor of 15% (see section 240(1) of the BCR) and, if applicable, the risk-weight floor set out in section 240(3) or (4) and the risk-weight cap for senior tranches (see section 241 of the BCR); and (ii) without taking into account any Part 7 CRM; (b) in the case of an NPL securitization exposure—the risk-weight applicable to the exposure determined in accordance with Division 11 of Part 7 of the BCR without taking into account any Part 7 CRM; (c) in the case of a re-securitization exposure—the risk-weight applicable to the exposure determined by using the SEC-SA or SEC-FBA— (i) after taking into account the risk-weight floor of 100% (see section 240(2) of the BCR) and if applicable, the risk-weight floor set out in
section 240(4) of the BCR; and
(ii) without taking into account any Part 7 CRM; (d) in the case of Part 7 CRM obtained for a securitization exposure—the risk￾weight applicable to— (i) the recognized collateral concerned determined in accordance with Part 4, 6 or 7 and in compliance with Division 5 of Part 7 of the BCR; or (ii) the credit protection provider of the recognized guarantee or recognized credit derivative contract concerned, as the case may be, determined in accordance with Part 4 or 6 and in compliance with Division 5 of Part 7 of the BCR; (e) in the case of assets held by a special purpose entity (SPE) in an eligible synthetic securitization transaction described in section 230(2A) of the

MA(BS)3(IIId)/P.4 (03/2025)
BCR—the weighted-average risk-weight of the assets determined in accordance with Part 4 of the BCR. A.1 Reporting of underlying exposures of securitization transaction where reporting AI is originating institution
14. The AI must report the underlying exposures of a non-eligible securitization
transaction as follows—
(a) report the underlying exposures in Form MA(BS)3(IIIa), Form MA(BS)3(IIIb) or Form MA(BS)3(IIIc) (if the underlying exposures are non-securitization exposures) or this Form (if the underlying exposures are securitization exposures), as if the underlying exposures had not been securitized; and (b) if the transaction is a synthetic securitization transaction, the underlying exposures must be reported without taking into account the effect of any credit risk mitigation (“CRM”) used for transferring the credit risk of the underlying exposures to other parties to the transaction.
15. If the AI has served a notice to the HKMA under section 230(3) of the BCR for
applying the treatment set out in section 230(1), (2) or (2A) of the BCR to the underlying exposures of an eligible securitization transaction— (a) in the case where the transaction is a traditional securitization transaction, the AI is not required to report the underlying exposures in any of Form MA(BS)3(IIIa), Form MA(BS)3(IIIb), Form MA(BS)3(IIIc) and this Form; (b) in the case where the transaction is a synthetic securitization transaction— (i) subject to subparagraph (ii), the AI must report the underlying exposures and the effect of the CRM used for transferring the credit risk of the underlying exposures in Form MA(BS)3(IIIa), Form MA(BS)3(IIIb) or Form MA(BS)3(IIIc) (if the underlying exposures are non-securitization exposures) or this Form (if the underlying exposures are securitization exposures); (ii) if tranched credit protection is obtained by the AI for the underlying exposures, the AI must report the underlying exposures and the effect of the CRM used for transferring the credit risk of the underlying exposures in this Form in accordance with paragraphs 16, 17, 35 and 36 below. A.2 Decomposition of exposures covered by tranched credit protection
16. Subject to paragraph 17, if a securitization exposure or non-securitization
exposure is covered by tranched credit protection (“protected exposure”), no matter whether the protection is provided or obtained by the reporting AI, the

MA(BS)3(IIId)/P.5 (03/2025) protected exposure must be decomposed 2 into a protected sub-tranche and an unprotected sub-tranche. The sub-tranches resulted from decomposing a non￾securitization exposure must be treated as securitization exposures for the purposes of calculating their RWAs.
17. When decomposing an exposure for which the AI has obtained tranched credit
protection, the decomposition must take into account— (a) if there is a maturity mismatch—the adjustment to the value of the credit protection required under section 246 of the BCR; and (b) if the tranched credit protection is in the form of recognized collateral and the reporting AI uses the comprehensive approach or Formula 18 or 19 in
Part 6 of the BCR to take into account the credit risk mitigation effect (“CRM
effect”) of the collateral—the adjustment to the value of the credit protection resulted from any applicable standard supervisory haircuts applied to the collateral. A.3 Reporting of derivative contracts entered into under securitization transactions
18. If a reporting AI’s securitization exposure is a default risk exposure arising from
a derivative contract and the risk-weight of the exposure is determined by using the SEC-IRBA, SEC-ERBA, SEC-SA or SEC-FBA, the default risk exposure must be reported in this Form. A.4 Reporting of eligible ABCP exposures risk-weighted by using the IAA
19. A reporting AI with an IAA approval to risk-weight eligible ABCP exposures by
using the IAA must include the eligible ABCP exposures in the amounts reported in columns (1) to (3) and (4) to (7) of Divisions C1 and C2, and the RWAs of the eligible ABCP exposures must also be reported separately in columns (3a) and (7a) of those Divisions. A.5 Treatment of default risk and dilution risk in respect of purchased receivables under SEC-IRBA
20. For cases where the default and dilution risks are not treated in an aggregated
manner, a reporting AI must determine in a prudent manner how the KIRB of the entire pool of the underlying exposures concerned should be calculated in order to adequately reflect the extent to which the AI is exposed to the two risks (see
section 252(3) of the BCR). Reporting AIs may refer to paragraphs 99.4 to 99.19
of Chapter CRE99 of the Basel Framework 3 for guidance.

2 The sub-tranches resulted from the decomposition are not considered as re-securitization exposures for capital adequacy purposes. 3 https://www.bis.org/basel_framework/chapter/CRE/99.htm?inforce=20230101&published=20200327
