ANNEX
1. Annex I is amended as follows:
(a) In Paragraph 4, the last sentence is deleted and the following subparagraph is added:
'The competent authorities may allow the capital requirement for an exchange-traded future to be equal to the margin required by the exchange if they are fully satisfied that it provides an accurate measure of the risk associated with the future and that it is at least equal to the capital requirement for a future that would result from a calculation made using the method set out in the remainder of this Annex or applying the internal models method described in Annex VIII. Until 31 December 2006 the competent authorities may also allow the capital requirement for an OTC derivatives contract of the type referred to in this paragraph cleared by a clearing house recognised by them to be equal to the margin required by the clearing house if they are fully satisfied that it provides an accurate measure of the risk associated with the derivatives contract and that it is at least equal to the capital requirement for the contract in question that would result from a calculation made using the method set out in the remainder of this Annex or applying the internal models method described in Annex VIII`.
(b) In paragraph 5, the third subparagraph is replaced by the following:
'The competent authorities shall require that the other risks, apart from the delta risk, associated with options are safeguarded against. The competent authorities may allow the requirement against a written exchange-traded option to be equal to the margin required by the exchange if they are fully satisfied that it provides an accurate measure of the risk associated with the option and that it is at least equal to the capital requirement against an option that would result from a calculation made using the method set out in the remainder of this Annex or applying the internal models method described in Annex VIII. Until 31 December 2006 the competent authorities may also allow the capital requirement for an OTC option cleared by a clearing house recognised by them to be equal to the margin required by the clearing house if they are fully satisfied that it provides an accurate measure of the risk associated with the option and that it is at least equal to the capital requirement for an OTC option that would result from a calculation made using the method set out in the remainder of this Annex or applying the internal models method described in Annex VIII. In addition they may allow the requirement on a bought exchange-traded or OTC option to be the same as that for the instrument underlying it, subject to the constraint that the resulting requirement does not exceed the market value of the option. The requirement against a written OTC option shall be set in relation to the instrument underlying it`.
(c) Paragraph 6 is replaced by the following:
'6. Warrants relating to debt instruments and equities shall be treated in the same way as options under paragraph 5`.
(d) Paragraph 33(i) is replaced by the following:
'(i) the equities shall not be those of issuers which have issued only traded debt instruments that currently attract an 8 % requirement in Table 1 appearing in paragraph 14 or that attract a lower requirement only because they are guaranteed or secured`.
2. Annex II is amended as follows:
(a) Paragraph 1 is replaced by the following:
'1. In the case of transactions in which debt instruments, equities and commodities (excluding repurchase and reverse repurchase agreements and securities or commodities lending and securities or commodities borrowing) are unsettled after their due delivery dates, an institution must calculate the price difference to which it is exposed. This is the difference between the agreed settlement price for the debt instrument, equity or commodity in question and its current market value, where the difference could involve a loss for the institution. It must multiply this difference by the appropriate factor in column A of the table appearing in paragraph 2 in order to calculate its capital requirement`.
(b) Paragraphs 3.1 and. 3.2 are replaced by the following:
'3.1. An institution shall be required to hold capital against counterparty risk if:
(i) it has paid for securities or commodities before receiving them or it has delivered securities or commodities before receiving payment for them;
and
(ii) in the case of cross-border transactions, one day or more has elapsed since it made that payment or delivery.
3.2. The capital requirement shall be 8 % of the value of the securities or commodities or cash owed to the institution multiplied by the risk weighting applicable to the relevant counterparty`.
(c) The heading before paragraph 4.1 and the first subparagraph of paragraph 4.1 are replaced by the following:
'Repurchase and reverse repurchase agreements, securities or commodities lending and borrowing
4.1. In the case of repurchase agreements and securities or commodities lending based on securities or commodities included in the trading book the institution shall calculate the difference between the market value of the securities or commodities and the amount borrowed by the institution or the market value of the collateral, where that difference is positive. In the case of reverse repurchase agreements and securities or commodities borrowing, the institution shall calculate the difference between the amount the institution has lent or the market value of the collateral and the market value of the securities or commodities it has received, where that difference is positive`.
3. Annex III is amended as follows:
(a) Paragraph 1 is replaced by the following:
'1. If the sum of an institution's overall net foreign-exchange position and its net gold position, calculated in accordance with the procedure set out below, exceeds 2 % of its total own funds, it shall multiply the sum of its net foreign-exchange position and its net gold position by 8 % in order to calculate its own-funds requirement against foreign-exchange risk.
Until 31 December 2004, the competent authorities may allow institutions to calculate their own-funds requirement by multiplying by 8 % the amount by which the sum of the overall net foreign-exchange position and the net gold position exceeds 2 % of the total own funds`.
(b) Paragraphs 3.1 and 3.2 are replaced by the following:
'3.1. Firstly, the institution's net open position in each currency (including the reporting currency) and in gold shall be calculated. This position shall consist of the sum of the following elements (positive or negative):
- the net spot position (i. e. all asset items less all liability items, including accrued interest, in the currency in question or, for gold, the net spot position in gold),
- the net forward position (i. e. all amounts to be received less all amounts to be paid under forward exchange and gold transactions, including currency and gold futures and the principal on currency swaps not included in the spot position),
- irrevocable guarantees (and similar instruments) that are certain to be called and likely to be irrecoverable,
- net future income/expenses not yet accrued but already fully hedged (at the discretion of the reporting institution and with the prior consent of the competent authorities, net future income/expenses not yet entered in accounting records but already fully hedged by forward foreign-exchange transactions may be included here). Such discretion must be exercised on a consistent basis,
- the net delta (or delta-based) equivalent of the total book of foreign-currency and gold options,
- the market value of other (i. e. non-foreign-currency and non-gold) options,
- any positions which an institution has deliberately taken in order to hedge against the adverse effect of the exchange rate on its capital ratio may be excluded from the calculation of net open currency positions. Such positions should be of a non-trading or structural nature and their exclusion, and any variation of the terms of their exclusion, shall require the consent of the competent authorities. The same treatment subject to the same conditions as above may be applied to positions which an institution has which relate to items that are already deducted in the calculation of own funds.
3.2. The competent authorities shall have the discretion to allow institutions to use the net present value when calculating the net open position in each currency and in gold`.
(c) Paragraph 4, first sentence, is replaced by the following:
'4. Secondly, net short and long positions in each currency other than the reporting currency and the net long or short position in gold shall be converted at spot rates into the reporting currency`.
(d) Paragraph 7 is replaced by the following:
'7. Secondly, until 31 December 2004, the competent authorities may allow institutions to apply an alternative method to those outlined in paragraphs 1 to 6 for the purposes of this Annex. The capital requirement produced by this method must be sufficient to exceed 2 % of the net open position as measured in paragraph 4 and, on the basis of an analysis of exchange-rate movements during all the rolling 10-working-day periods over the preceding three years, to exceed the likely loss 99 % or more of the time.
The alternative method described in the first subparagraph may only be used under the following conditions:
(i) the calculation formula and the correlation coefficients are set by the competent authorities, based on their analysis of exchange-rate movements;
(ii) the competent authorities review the correlation coefficients regularly in the light of developments in foreign-exchange markets`.
4. Annex V is amended as follows:
(a) Paragraph 2, first sentence, is replaced by the following:
'Notwithstanding paragraph 1, the competent authorities may permit those institutions which are obliged to meet the own-funds requirements laid down in Annexes I, II, III, IV, VI, VII and VIII to use an alternative definition when meeting those requirements only`.
(b) Paragraph 4 is replaced by the following:
'4. The subordinated loan capital referred to in paragraph 2(c) may not exceed a maximum of 150 % of the original own funds left to meet the requirements laid down in Annexes I, II, III, IV, VI, VII, and VIII and may approach that maximum only in particular circumstances acceptable to the relevant authorities`.
(c) Paragraphs 6 and 7 are replaced by the following:
'6. The competent authorities may permit investment firms to exceed the ceiling for subordinated loan capital prescribed in paragraph 4 if they judge it prudentially adequate and provided that the total of such subordinated loan capital and the items referred to in paragraph 5 does not exceed 200 % of the original own funds left to meet the requirements imposed in Annexes I, II, III, IV, VI, VII and VIII or 250 % of the same amount where investment firms deduct item 2(d) referred to in paragraph 2 when calculating own funds.
7. The competent authorities may permit the ceiling for subordinated loan capital prescribed in paragraph 4 to be exceeded by a credit institution if they judge it prudentially adequate and provided that the total of such subordinated loan capital and the items referred to in paragraph 5 does not exceed 250 % of the original own funds left to meet the requirements imposed in Annexes I, II, III, VI, VII and VIII`.
5. The following Annexes are added:
'ANNEX VII
COMMODITIES RISK
1. Each position in commodities or commodity derivatives shall be expressed in terms of the standard unit of measurement. The spot price in each commodity shall be expressed in the reporting currency.
2. Positions in gold or gold derivatives shall be considered as being subject to foreign-exchange risk and treated according to Annex III or Annex VIII, as appropriate, for the purpose of calculating market risk.
3. For the purposes of this Annex, positions which are purely stock financing may be excluded from the commodities risk calculation only.
4. The interest-rate and foreign-exchange risks not covered by other provisions of this Annex shall be included in the calculation of general risk for traded debt instruments and in the calculation of foreign-exchange risk.
5. When the short position falls due before the long position, institutions shall also guard against the risk of a shortage of liquidity which may exist in some markets.
6. For the purpose of paragraph 19, the excess of an institution's long (short) positions over its short (long) positions in the same commodity and identical commodity futures, options and warrants shall be its net position in each commodity. The competent authorities shall allow positions in derivative instruments to be treated, as laid down in paragraphs 8, 9 and 10, as positions in the underlying commodity.
7. The competent authorities may regard the following positions as positions in the same commodity:
- positions in different sub-categories of commodities in cases where the sub-categories are deliverable against each other,
and
- positions in similar commodities if they are close substitutes and if a minimum correlation of 0,9 between price movements can be clearly established over a minimum period of one year.
Particular instruments
8. Commodity futures and forward commitments to buy or sell individual commodities shall be incorporated in the measurement system as notional amounts in terms of the standard unit of measurement and assigned a maturity with reference to expiry date. The competent authorities may allow the capital requirement for an exchange-traded future to be equal to the margin required by the exchange if they are fully satisfied that it provides an accurate measure of the risk associated with the future and that it is at least equal to the capital requirement for a future that would result from a calculation made using the method set out in the remainder of this Annex or applying the internal models method described in Annex VIII. Until 31 December 2006 the competent authorities may also allow the capital requirement for an OTC commodity derivatives contract of the type referred to in this paragraph cleared by a clearing house recognised by them to be equal to the margin required by the clearing house if they are fully satisfied that it provides an accurate measure of the risk associated with the derivatives contract and that it is at least equal to the capital requirement for the contract in question that would result from a calculation made using the method set out in the remainder of this Annex or applying the internal models method described in Annex VIII.
9. Commodity swaps where one side of the transaction is a fixed price and the other the current market price shall be incorporated into the maturity ladder approach as a series of positions equal to the notional amount of the contract, with one position corresponding with each payment on the swap and slotted into the maturity ladder set out in the table appearing in paragraph 13. The positions would be long positions if the institution is paying a fixed price and receiving a floating price and short positions if the institution is receiving a fixed price and paying a floating price.
Commodity swaps where the sides of the transaction are in different commodities are to be reported in the relevant reporting ladder for the maturity ladder approach.
10. Options on commodities or on commodity derivatives shall be treated as if they were positions equal in value to the amount of the underlying to which the option refers, multiplied by its delta for the purposes of this Annex. The latter positions may be netted off against any offsetting positions in the identical underlying commodity or commodity derivative. The delta used shall be that of the exchange concerned, that calculated by the competent authorities or, where none of those is available or for OTC options, that calculated by the institution itself, subject to the competent authorities being satisfied that the model used by the institution is reasonable.
However, the competent authorities may also prescribe that institutions calculate their deltas using a methodology specified by the competent authorities.
The competent authorities shall require that the other risks, apart from the delta risk, associated with commodity options are safeguarded against. The competent authorities may allow the requirement for a written exchange-traded commodity option to be equal to the margin required by the exchange if they are fully satisfied that it provides an accurate measure of the risk associated with the option and that it is at least equal to the capital requirement against an option that would result from a calculation made using the method set out in the remainder of this Annex or applying the internal models method described in Annex VIII. Until 31 December 2006 the competent authorities may also allow the capital requirement for an OTC commodity option cleared by a clearing house recognised by them to be equal to the margin required by the clearing house if they are fully satisfied that it provides an accurate measure of the risk associated with the option and that it is at least equal to the capital requirement for an OTC option that would result from a calculation made using the method set out in the remainder of this Annex or applying the internal models method described in Annex VIII. In addition they may allow the requirement on a bought exchange-traded or OTC commodity option to be the same as that for the commodity underlying it, subject to the constraint that the resulting requirement does not exceed the market value of the option. The requirement for a written OTC option shall be set in relation to the commodity underlying it.
11. Warrants relating to commodities shall be treated in the same way as commodity options under paragraph 10.
12. The transferor of commodities or guaranteed rights relating to title to commodities in a repurchase agreement and the lender of commodities in a commodities lending agreement shall include such commodities in the calculation of its capital requirement under this Annex.
(a) Maturity ladder approach
13. The institution shall use a separate maturity ladder in line with the following table for each commodity. All positions in that commodity and all positions which are regarded as positions in the same commodity pursuant to paragraph 7 shall be assigned to the appropriate maturity bands. Physical stocks shall be assigned to the first maturity band.
>TABLE>
14. Competent authorities may allow positions which are, or are regarded pursuant to paragraph 7 as, positions in the same commodity to be offset and assigned to the appropriate maturity bands on a net basis for:
- positions in contracts maturing on the same date,
and
- positions in contracts maturing within 10 days of each other if the contracts are traded on markets which have daily delivery dates.
15. The institution shall then work out the sum of the long positions and the sum of the short positions in each maturity band. The amount of the former (latter) which are matched by the latter (former) in a given maturity band shall be the matched positions in that band, while the residual long or short position shall be the unmatched position for the same band.
16. That part of the unmatched long (short) position for a given maturity band that is matched by the unmatched short (long) position for a maturity band further out shall be the matched position between two maturity bands. That part of the unmatched long or unmatched short position that cannot be thus matched shall be the unmatched position.
17. The institution's capital requirement for each commodity shall be calculated on the basis of the relevant maturity ladder as the sum of the following:
(i) the sum of the matched long and short positions, multiplied by the appropriate spread rate as indicated in the second column of the table appearing in paragraph 13 for each maturity band and by the spot price for the commodity;
(ii) the matched position between two maturity bands for each maturity band into which an unmatched position is carried forward, multiplied by 0,6 % (carry rate) and by the spot price for the commodity;
(iii) the residual unmatched positions, multiplied by 15 % (outright rate) and by the spot price for the commodity.
18. The institution's overall capital requirement for commodities risk shall be calculated as the sum of the capital requirements calculated for each commodity according to paragraph 17.
(b) Simplified approach
19. The institution's capital requirement for each commodity shall be calculated as the sum of:
(i) 15 % of the net position, long or short, multiplied by the spot price for the commodity;
(ii) 3 % of the gross position, long plus short, multiplied by the spot price for the commodity.
20. The institution's overall capital requirement for commodities risk shall be calculated as the sum of the capital requirements calculated for each commodity according to paragraph 19.
ANNEX VIII
INTERNAL MODELS
1. The competent authorities may, subject to the conditions laid down in this Annex, allow institutions to calculate their capital requirements for position risk, foreign-exchange risk and/or commodities risk using their own internal risk-management models instead of or in combination with the methods described in Annexes I, III and VII. Explicit recognition by the competent authorities of the use of models for supervisory capital purposes shall be required in each case.
2. Recognition shall only be given if the competent authority is satisfied that the institution's risk-management system is conceptually sound and implemented with integrity and that, in particular, the following qualitative standards are met:
(i) the internal risk-measurement model is closely integrated into the daily risk-management process of the institution and serves as the basis for reporting risk exposures to senior management of the institution;
(ii) the institution has a risk control unit that is independent from business trading units and reports directly to senior management. The unit must be responsible for designing and implementing the institution's risk-management system. It shall produce and analyse daily reports on the output of the risk-measurement model and on the appropriate measures to be taken in terms of trading limits;
(iii) the institution's board of directors and senior management are actively involved in the risk-control process and the daily reports produced by the risk-control unit are reviewed by a level of management with sufficient authority to enforce both reductions of positions taken by individual traders as well as in the institution's overall risk exposure;
(iv) the institution has sufficient numbers of staff skilled in the use of sophisticated models in the trading, risk-control, audit and back-office areas;
(v) the institution has established procedures for monitoring and ensuring compliance with a documented set of internal policies and controls concerning the overall operation of the risk-measurement system;
(vi) the institution's models have a proven track record of reasonable accuracy in measuring risks;
(vii) the institution frequently conduct a rigorous programme of stress testing and the results of these tests are reviewed by senior management and reflected in the policies and limits it sets;
(viii) the institution must conduct, as part of its regular internal auditing process, an independent review of its risk-measurement system. This review must include both the activities of the business trading units and of the independent risk-control unit. At least once a year, the institution must conduct a review of its overall risk-management process. The review must consider:
- the adequacy of the documentation of the risk-management system and process and the organisation of the risk-control unit,
- the integration of market risk measures into daily risk management and the integrity of the management information system,
- the process the institution employs for approving risk-pricing models and valuation systems that are used by front and back-office personnel,
- the scope of market risks captured by the risk-measurement model and the validation of any significant changes in the risk-measurement process,
- the accuracy and completeness of position data, the accuracy and appropriateness of volatility and correlation assumptions, and the accuracy of valuation and risk sensitivity calculations,
- the verification process the institution employs to evaluate the consistency, timeliness and reliability of data sources used to run internal models, including the independence of such data sources,
and
- the verification process the institution uses to evaluate back-testing that is conducted to assess the model's accuracy.
3. The institution shall monitor the accuracy and performance of its model by conducting a back-testing programme. The back-testing has to provide for each business day a comparison of the one-day value-at-risk measure generated by the institution's value by the end of the subsequent business day. Competent authorities shall examine the institution's capability to perform back-testing on both actual and hypothetical changes in the portfolio's value. Back-testing on hypothetical changes in the portfolio's value is based on a comparison between the portfolio's end-of-day value and, assuming unchanged positions, its value at the end of the subsequent day. Competent authorities shall require institutions to take appropriate measures to improve their back-testing programme if deemed deficient.
4. For the purpose of calculating capital requirements for specific risk associated with traded debt and equity positions, the competent authorities may recognise the use of an institution's internal model if in addition to compliance with the conditions in the remainder of this Annex the model:
- explains the historical price variation in the portfolio,
- captures concentration in terms of magnitude and changes of composition of the portfolio,
- is robust to an adverse environment,
- is validated through back-testing aimed at assessing whether specific risk is being accurately captured. If competent authorities allow this back-testing to be performed on the basis of relevant sub-portfolios, these must be chosen in a consistent manner.
5. Institutions using internal models which are not recognised in accordance with paragraph 4 shall be subject to a separate capital charge for specific risk as calculated according to Annex I.
6. For the purpose of paragraph 10(ii) the results of the institution's own calculation shall be scaled up by a multiplication factor of at least 3.
7. The multiplication factor shall be increased by a plus-factor of between 0 and 1 in accordance with the following table, depending on the number of overshootings for the most recent 250 business days as evidenced by the institution's back-testing. Competent authorities shall require the institutions to calculate overshootings consistently on the basis of back-testing either on actual or on hypothetical changes in the portfolio's value. An overshooting is a one-day change in the portfolio's value that exceeds the related one-day value-at-risk measure generated by the institution's model. For the purpose of determining the plus-factor the number of overshootings shall be assessed at least quarterly.
>TABLE>
The competent authorities can, in individual cases and owing to an exceptional situation, waive the requirement to increase the multiplication factor by the plus-factor according to the above table, if the institution has demonstrated to the satisfaction of the competent authorities that such an increase is unjustified and that the model is basically sound.
If numerous overshootings indicate that the model is not sufficiently accurate, the competent authorities shall revoke the model's recognition or impose appropriate measures to ensure that the model is improved promptly.
In order to allow competent authorities to monitor the appropriateness of the plus-factor on an ongoing basis, institutions shall notify promptly, and in any case no later than within five working days, the competent authorities of overshootings that result form their back-testing programme and that would according to the above table imply an increase of a plus-factor.
8. If the institution's model is recognised by the competent authorities in accordance with paragraph 4 for the purpose of calculating capital requirements for specific risk, the institution shall increase its capital requirement calculated pursuant to paragraphs 6, 7 and 10 by a surcharge in the amount of either:
(i) the specific risk portion of the value-at-risk measure which should be isolated according to supervisory guidelines; or, at the institution's option,
(ii) the value-at-risk measures of sub-portfolios of debt and equity positions that contain specific risk.
Institutions using option (ii) are required to identify their sub-portfolio structure beforehand and should not change it without the consent of the competent authorities.
9. The competent authorities may waive the requirement pursuant to paragraph 8 for a surcharge if the institution demonstrates that in line with agreed international standards its model accurately captures also the event risk and default risk for its traded debt and equity positions.
10. Each institution must meet a capital requirement expressed as the higher of:
(i) its previous day's value-at-risk number measured according to the parameters specified in this Annex;
(ii) an average of the daily value-at-risk measures on each of the preceding 60 business days, multiplied by the factor mentioned in paragraph 6, adjusted by the factor mentioned in paragraph 7.
11. The calculation of value-at-risk shall be subject to the following minimum standards:
(i) at least daily calculation of value-at-risk;
(ii) a 99th percentile, one-tailed confidence interval;
(iii) a 10-day equivalent holding period;
(iv) an effective historical observation period of at least one year except where a shorter observation period is justified by a significant upsurge in price volatility;
(v) three-monthly data set updates.
12. The competent authorities shall require that the model captures accurately all the material price risks of options or option-like positions and that any other risks not captured by the model are covered adequately by own funds.
13. The competent authorities shall require that the risk-measurement model captures a sufficient number of risk factors, depending on the level of activity of the institution in the respective markets. As a minimum, the following provisions shall be respected:
(i) for interest rate risk, the risk-measurement system shall incorporate a set of risk factors corresponding to the interest rates in each currency in which the institution has interest rate sensitive on- or off-balance sheet positions. The institution shall model the yield curves using one of the generally accepted approaches. For material exposures to interest-rate risk in the major currencies and markets, the yield curve shall be divided into a minimum of six maturity segments, to capture the variations of volatility of rates along the yield curve. The risk-measurement system must also capture the risk of less than perfectly correlated movements between different yield curves;
(ii) for foreign-exchange risk, the risk-measurement system shall incorporate risk factors corresponding to gold and to the individual foreign currencies in which the institution's positions are denominated;
(iii) for equity risk, the risk-measurement system shall use a separate risk factor at least for each of the equity markets in which the institution holds significant positions;
(iv) for commodity risk, the risk-measurement system shall use a separate risk factor at least for each commodity in which the institution holds significant positions. The risk-measurement system must also capture the risk of less than perfectly correlated movements between similar, but not identical, commodities and the exposure to changes in forward prices arising from maturity mismatches. It shall also take account of market characteristics, notably delivery dates and the scope provided to traders to close out positions.
14. The competent authorities may allow institutions to use empirical correlations within risk categories and across risk categories if they are satisfied that the institution's system for measuring correlations is sound and implemented with integrity`.
