 |  Ladies and Gentlemen:  Bank One Corporation is pleased to offer comment on the interagency 
        document - `Advance Notice of Proposed Rulemaking' (ANPR) - outlining 
        the proposed implementation of the new Basel Capital Accord in the 
        United States. Our response highlights specific areas within the 
        proposal that differ from industry best practice. Primary issues of 
        concern center on Pillar I calibration, the securitization framework, 
        operational risk and disclosure requirements.  We understand the need to balance the complexity required for better 
        risk differentiation with the simplicity required to ensure consistent 
        implementation. As such, we offer practical alternatives that provide a 
        framework more consistent with industry practice without sacrificing the 
        spirit of the proposal. Finally, an appendix contains more detailed 
        responses to some of the questions raised within the ANPR that are most 
        important to Bank One.  True Minimum Standard  Note: We agree with the recently reported change to the Basel 
        framework that excludes expected loss from capital requirements. 
        Presumably the modification will reduce risk-weighted assets by 12.5 
        times expected loss. In addition, reserve adequacy should be based on 
        one year expected loss to capture the fact reserves are replenished 
        over time through margin income and will become available to cover 
        expected losses beyond one year.  The fundamental premise of Pillar I is that it should establish a 
        true minimum capital standard (i.e., represent the lowest solvency 
        standard tolerable for regulated firms), relying on Pillars II and III 
        to motivate firms to operate at an appropriate level of capitalization. 
        There are numerous instances in the proposal where minimums and limits 
        introduce a degree of conservatism to the capital calculation. These 
        include limited recognition of risk mitigation tools, limited 
        recognition of collateral on certain loans, and minimum risk weights for 
        certain assets. The cumulative effect of this conservatism produces a 
        capital standard well above a true minimum.  Proper calibration of the risk weight functions is critical to a 
        regulatory framework in order to avoid non-economic incentives or 
        barriers to fair competition. Current calibration results in regulatory 
        capital requirements that exceed Bank One's internal estimates of 
        economic capital for certain assets. The root cause appears to be the 
        adoption of pre-defined asset value correlation (AVC) for each asset 
        type on the balance sheet. The discrepancy arises from the assumed 
        relationship between probability of default (PD) and AVC embedded in the 
        risk weight function. While we accept that low risk borrowers typically 
        hold larger, more diversified asset portfolios leading to higher AVC, 
        analysis of our retail and commercial data has not produced the 
        magnitude of the inverse relationship the risk weight formulas suggest. 
        A more accurate level of capital would result from using an 
        institution's internal estimate of AVC and volatility as inputs to a 
        single risk weight function.  The following three examples illustrate our calibration concerns:  
Prime Credit Card Assets - (regulatory requirements exceed 
          economic capital estimates) - The loss volatility in our prime credit 
          card portfolio data is too low to support the level of capital 
          resulting under the proposal. This is particularly true for highest 
          quality exposures, which represents the majority of our portfolio. Our 
          credit card data stressed to three times its observed volatility fails 
          to produce economic capital factors as high as those implied by the 
          risk weight function. Quantifying the difference, credit card assets 
          with PD less than five percent attract economic capital between one 
          and three percent using the stressed Bank One loss volatility, where 
          the proposal indicates regulatory capital requirements of more than 
          five percent.  Second Lien Home Equity Loans - (asset type directed to 
          wrong risk weight function) - The residential mortgage curve is 
          calibrated for traditional first mortgages rather than high combined 
          loan-to-value (CLTV) second mortgages or home equity loans. Given the 
          higher loss severity on these loans relative to traditional first 
          mortgages, the mortgage risk weight function produces unusually high 
          capital requirements. As a result, the capital requirement for a high 
          CLTV second mortgage is greater than it is for an unsecured credit 
          card loan to the same borrower.  The mortgage risk weight function uses a constant 15% AVC across PD 
          to capture the influence of housing values on losses. High CLTV second 
          mortgages with very little collateral protection are much less 
          susceptible to changes in the underlying housing value than 
          traditional first mortgages. The highest CLTV second mortgages, 
          particularly those subordinate to high loan to value first mortgages, 
          are effectively unsecured loans.  Analysis of internal data demonstrates that borrowers in the 
          extreme circumstance of abandoning their residence rarely continue to 
          pay their credit card bill. In other words, a mortgage is not 
          subordinate to a credit card. As LTV increases and collateral 
          protection goes away, capital requirements for a second mortgage 
          should approach but never exceed the capital requirement for an 
          unsecured credit card loan to the same borrower.  Wholesale Lending - (regulatory requirements exceed 
          economic capital estimates) - The wholesale risk weight function 
          produces capital requirements 25 to 50 percent higher than economic 
          capital estimates for investment grade assets. This, too, is a result 
          of the magnitude of the inverse relationship between PD and AVC 
          assumed in the risk weight function. We have not found evidence to 
          support this assumption for wholesale assets. Our analysis does show a 
          statistically significant relationship between an obligor's sales 
          volume and AVC, but little statistical significance to the 
          relationship between sales volume and PD.  Securitization - Multi-Seller CP Conduits  Another recently announced change to the Basel II framework is the 
        elimination of the supervisory formula approach for unrated 
        securitization exposures funded through commercial paper conduits. With 
        the elimination of the supervisory formula, we support a ratings based 
        approach (RBA) using internally assigned ratings. Monitored under Pillar 
        II, internal ratings will directly recognize credit enhancements 
        provided by over-collateralization and other structural components 
        resulting in a comprehensive view of the risk of the transaction. This 
        will align regulatory capital requirements with industry risk 
        measurement practices.  Internal ratings would be mapped to the RBA risk weight tables to 
        determine capital, but the existing tables do not provide for low loss 
        given default tranches such as the senior, very thick tranches generally 
        present in conduit transactions. The existing tables also fail to 
        recognize risk mitigation structures, which include asset quality tests 
        that protect the liquidity bank from funding defaulted assets in the 
        event of liquidity draw and 364-day renewable liquidity facilities that 
        allow for annual re-evaluation and tightening of the structural features 
        in the transaction when necessary. These risk mitigation tools 
        significantly reduce the risk of a conduit transaction versus similarly 
        rated transactions in the term ABS market. Supplementing the currently 
        proposed risk weight table with an additional column and/or credit 
        conversion factor would provide proper risk differentiation for these 
        types of assets.  The original proposal included a separate evaluation of dilution 
        risk. As internal ratings implicitly recognize all structural risks 
        including dilution risk, it would be a double count to include a 
        separate explicit analysis of dilution risk within an internal ratings 
        based approach. Internal ratings capture not only exposure to dilution 
        risk, but also the impact of the mitigating structural components such 
        as recourse to the seller, reserves and over-collateralization.  Program wide credit enhancement provides umbrella coverage to 
        multiple conduit securitizations and `overlaps' coverage provided by 
        deal specific liquidity facilities. As currently proposed, the 
        regulatory capital requirement is established based on the riskiest of 
        the overlapping pieces. Specifically, the proposal sets aggregate 
        capital for the combined exposure based on the worst rated deal covered 
        by the program wide credit enhancement. It would be more accurate to 
        measure the capital requirement for the program wide credit enhancement 
        against the weighted average risk of all assets covered under the 
        protection. Using the rating of the worst quality asset leads to a large 
        overstatement of capital requirements for some umbrella coverage and 
        could discourage banks from investing in this mitigation tool.  Securitization - Revolving Assets  Previously we noted that the risk weight function for credit card 
        assets produces capital requirements too high for the given risk. At the 
        same time, the proposal to provide capital relief for credit card 
        securitizations understates the risk retained by the originating firm. 
        While the effect of the two may offset, individually they may drive 
        non-economic decisions.  The treatment of revolving securitizations is inconsistent with the 
        stated objective of providing capital relief only when meaningful risk 
        transference occurs. This form of securitization functions primarily as 
        a financing vehicle, which utilizes structural mechanisms to insulate 
        the investor from the credit risk of the receivables in all but 
        catastrophic events. The proposed framework for revolving structures 
        creates a `cliff effect' requiring increased capital as spread income 
        deteriorates on the securitized pool of assets. This is the only place 
        in Basel where capital is required as the capital event approaches and 
        forces originators to raise capital when it becomes too expensive or is 
        the least available.  Operational Risk  Bank One supports directly addressing operational risk within the 
        regulatory framework. Implementation under the AMA guidelines is an 
        important step towards a principles-based internal model approach. 
        Nevertheless, it will be important to coordinate regulatory oversight 
        with other governmental guidance such as FDICIA and Sarbanes-Oxley. The 
        following points highlight our concerns with the current proposal:  
Definition of Capital - Removal of expected loss from the 
          definition of capital should extend to operational risk capital as 
          well. The connection between spread or other income and operational 
          loss expense is less clear than it is for credit risk; however, banks 
          budget, reserve and pay for expected operational losses through the 
          normal course of business. As written, the proposal casts doubt on a 
          bank's ability to demonstrate that EL is accounted for through 
          reserves, operational costs and pricing.  Analytic Limitations - The nature of operational risk data 
          and the amount of data currently available limit the ability to 
          objectively infer robust capital factors using purely statistical 
          methods. Establishing meaningful event correlation and populating the 
          `tail' of operational loss distributions will require input beyond 
          tangible loss data.  
A standard of "substantiated judgment", with Pillar II oversight, 
          should enhance or replace direct statistical analysis.  Disclosure  We support the notion of market discipline through increased 
        disclosure in conjunction with a true minimum regulatory capital 
        standard established through Pillar I. However, we are concerned about 
        potential competitive inequalities arising from the Pillar III 
        requirements, as financial service companies falling under its 
        governance will disclose information that other less regulated 
        industries will not.  Given its complexity, the disclosure mandated by the proposal is not 
        likely to benefit the majority of investors. As the markets have 
        demonstrated an ability to drive increased transparency with minimal 
        impetus from regulatory bodies, we advocate a market discipline that 
        strikes an appropriate balance between the informational value of 
        disclosure and the benefit of reduced capital.  Disclosure is appropriate only when industry consensus around 
        definitions and measurement standards has been achieved. While the 
        proposal provides recommended disclosure formats, it does not ensure 
        comparability across institutions, as much of the underlying data is 
        subjective in nature. The lack of comparability may lead to 
        misinterpretation and make meaningful comparisons across firms 
        difficult. This issue is already apparent in disclosures surrounding 
        interest rate risk. We encourage the re-examination of the balance 
        between supervisory oversight under Pillar II and market disclosure 
        under Pillar III as one means to address these concerns. The appendix 
        highlights several specific concerns regarding the Pillar III draft 
        paper as currently written.  Conclusion  While we agree with recent changes announced regarding treatment of 
        expected loss and the supervisory formula, we remain concerned about 
        calibration of the minimum standard and certain details of the treatment 
        of securitizations. The implementation detailed in the ANPR represents 
        significant progress toward the common goal of establishing a more 
        robust riskbased capital standard for the financial services industry. 
        We are optimistic that the remaining issues can be resolved 
        satisfactorily for the industry  Sincerely,  Heidi Miller Executive Vice President and Chief Financial Officer

   APPENDIX  General Framework 
 ANPR: What are commenters' views on the relative pros and 
          cons of a bifurcated regulatory framework versus a single regulatory 
          framework? What are the competitive implications for community and 
          mid-size regional banks?  If regulatory minimum capital requirements declined under the 
          advanced approaches, would the dollar amount of capital these banking 
          organizations hold also be expected to decline?  The Agencies seek comment on whether changes should be made to 
          the existing general risk-based capital rules to enhance the 
          risk-sensitivity or to reflect changes in the business lines or 
          activities of banking organizations without imposing undue regulatory 
          burden or complication. In particular, the Agencies seek comment on 
          whether any changes to the general risk-based capital rules are 
          necessary or warranted to address any competitive equity concerns 
          associated with the bifurcated framework.  ONE: 
        We support the move to a more risk sensitive regulatory framework; 
        however, we continue to view Pillar I as a true minimum capital 
        standard. Whether an institution operates as an advanced bank or a 
        non-advanced bank, their internally estimated economic capital should be 
        higher than the Pillar I standard. Pillars II and III will function to 
        drive banks to the appropriate capital levels.  Bank One understands the practical value of a bifurcated 
        implementation of Basel II, however, there are potential issues with 
        this varied approach. To avoid penalizing advanced banks, the proposal 
        should not require a substantial amount of overhead for the sole purpose 
        of meeting A-IRB requirements. Also, in many local markets where 
        nonadvanced banks are in price competition with advanced banks, there 
        may be a competitive disadvantage that results from adverse market 
        perceptions of being a "nonadvanced" bank.  Bank One recommends that in a bifurcated framework, non-advanced 
        banks use the new standardized approach for Pillar I. The standardized 
        approach is more risk sensitive than the current regulatory framework 
        and also includes explicit recognition of operational risks. Adopting 
        the standardized approach will help move and encourage non-advanced 
        banks in the direction of the advanced framework.  ANPR: The Agencies are interested in comment on the extent to which 
        alternative approaches to regulatory capital are implemented across 
        national boundaries might create burdensome implementation costs for the 
        US. subsidiaries of foreign banks.  ONE: 
 The home supervisor, rather than the host country's supervisor, 
        should have jurisdiction over the regulatory capital rules for 
        internationally active banks in order to minimize the number of 
        regulations those banks must follow. In the event that the host 
        supervisory is given jurisdiction for Basel implementation, using a 
        standardized approach for assets under foreign jurisdiction should have 
        no negative impact on our advanced status within the United States.
 ANPR:
 Given the general principle that the advanced approaches are expected 
        to be implemented at the same time across all material portfolios, 
        business lines, and geographic regions, to what degree should the 
        Agencies be concerned that, for example, data may not be available for 
        key portfolios, business lines, or regions? Is there a need for further 
        transitional arrangements? Please be specific, including suggested 
        durations for such transitions.
 ONE: 
 Assuming there are no major changes to the structure of the 
        framework, Bank One will meet the standard for becoming an IRB bank by 
        the projected implementation date. Although the retail and operational 
        risk frameworks are less developed, we do not foresee any issues 
        regarding these areas that will prevent Bank One from meeting the 
        deadline. Throughout the implementation process, Bank One will continue 
        to engage in constructive dialogue with Supervisors as issues arise. 
        Beyond the implementation date, we expect to continue to refine and 
        enhance our analysis to ensure that our capital levels will be 
        indicative of the most accurate assessment of risk available.
 ANPR:
 What are the advantages and disadvantages of the A-IRB approach 
        relative to alternatives, including those that would allow greater 
        flexibility to use internal models and those that would be more cautious 
        in incorporating statistical techniques (such as greater use of credit 
        ratings by external rating agencies)?
 ONE:
 It is difficult to capture accurately the full spectrum of risk 
        across products and lines of business with only one wholesale and three 
        retail risk weight functions. Calibration will help with the overall 
        capital level, but regulatory requirements for some risk segments will 
        be too high and others too low. A more accurate alternative is to allow 
        advanced firms to provide their own estimates for asset value 
        correlation and volatility. Advanced banks already produce parameter 
        driven, risk sensitive economic capital requirements based on sophisticated internal models. Using asset value correlation 
        assumptions in the regulatory framework is the next logical step to 
        capital requirements fully based on internal models.
 ANPR:
 Should the A-IRB capital regime be based on a framework that 
        allocates capital to EL plus UL, or to UL only? Which approach would 
        more closely align the regulatory framework to the internal capital 
        allocation techniques currently used by large institutions?
 
 ONE:
 We applaud Basel II's recent change excluding EL from capital, as it 
        will help to align the Accord with industry practice. Given the removal 
        of EL from capital, we agree with the adjustments to the treatment of 
        FMI and reserves.  Wholesale Exposures   ANPR:  If the Agencies include a SME adjustment, are the $50 million 
        threshold and the proposed approach to measurement of borrower size 
        appropriate? What standards should be applied to the borrower size 
        measurement (for example, frequency of measurement, use of size buckets 
        rather than precise measurements)?   ONE:
 A framework that includes internally estimated AVC as an input avoids 
        the need for the $50 million threshold. We observe in our data a 
        significant correlation between an obligor's sales size and AVC. This 
        means that smaller firms have lower AVC and subsequently less capital 
        directly achieving the objective intended by the threshold without 
        resorting to arbitrary means. However, if the proposal uses a threshold 
        to recognize the size effect, there should be a smooth transition across 
        it (as in the current proposal) rather than a stair-step or on-off 
        transition. The phase-in of the size benefit embedded in the current 
        proposal minimizes the risk of gaming the formula.
 
 ANPR:
 
 The Agencies invite comment on the competitive impact of treating 
        defined classes of CRE differently. What are commenters' views on an 
        alternative approach where there is only one risk weight function for 
        all CRE? If a single asset correlation treatment were considered, what 
        would be the appropriate asset correlations to employ within a single 
        risk-weight function applied to all CRE exposures?
 ONE:  Given that a small percentage of commercial real estate loans will be 
        considered HVCRE, Bank One is not in favor of lumping all commercial 
        real estate together and subjecting this aggregated portfolio to a 
        higher capital formula. However, Bank One welcomes the consolidation of 
        commercial real estate exposure if such exposures could utilize the 
        standard A-IRB formula. We propose that an acceptable approach to 
        commercial real estate is to require that the LGD either incorporate the 
        high correlation to PD or that a conservative approach to real estate 
        values be used for the LGD factor.  Retail Exposures   ANPR:  The Agencies are interested in comment on whether the proposed $1 
        million threshold provides the appropriate dividing line between those 
        SME exposures that banking organizations should be allowed to treat on a 
        pooled basis under the retail A-IRB framework and those SME exposures 
        that should be rated individually and treated under the wholesale A-IRB 
        framework. 
 ONE:
 Rather than a dollar amount threshold, regulatory treatment should be 
        aligned with how these assets are underwritten and managed. Bank One 
        underwrites small business loans both using credit scoring tools similar 
        to consumer loans and incorporating judgmental underwriting similar to 
        commercial loans. The proposal should provide banks the flexibility to 
        decide which risk management method is appropriate for each asset.  ANPR:
 The Agencies are seeking comment on the proposed definitions of the 
        retail A-IRB exposure category and sub-categories. Do the proposed 
        categories provide a reasonable balance between the need for 
        differential treatment to achieve risk-sensitivity and the desire to 
        avoid excessive complexity in the retail A-IRB framework?
 ONE:
 As noted previously, it is difficult to distill retail risk down to 
        three risk weight functions. We would prefer a framework where AVC is a 
        direct input to the capital formula. However, without directly 
        addressing AVC, Bank One supports the possibility of adding exposure 
        categories or sub-categories if the industry data suggests that there is 
        indeed separation of asset value correlation between product groups. 
        Calibrating the AVC curves for retail is essential towards deriving 
        meaningful minimum capital requirements, since they will be the main 
        driver of any differences between regulatory and internal economic 
        capital factors.
 ANPR:  The Agencies are interested in comments and specific proposals 
        concerning methods for incorporating undrawn credit card lines that are 
        consistent with the risk characteristics and loss and default histories 
        of this line of business.   The Agencies are interested in further information on market 
        practices in this regard, in particular the extent to which banking 
        organizations remain exposed to risks associated with such accounts. 
        More broadly, the Agencies recognize that undrawn credit card lines are 
        significant in both of the contexts discussed above, and are 
        particularly interested in views on the appropriate retail IRB treatment 
        of such exposures. 
 ONE:
 The risk of undrawn retail commitments should be addressed directly 
        through estimates of EAD rather than incorporating the risk into LGD 
        estimates. To use LGD adjustments properly, they must be a function of 
        the size of the unfunded commitment, which is basically the same as 
        estimating EAD. Conversely, if LGD estimates are independent of the size 
        of the unfunded commitment then the estimate will not properly 
        differentiate similar commitments with the same outstanding balance but 
        significantly different unfunded lines.  Our data suggests that EAD is significantly correlated to PD. Using 
        EAD as a function of PD ensures that EAD is sensitive to current 
        utilization, without creating a more complex framework.  Whether securitized or not, unused commitments represent exposure to 
        the originating institution. Investors in card securitizations are not 
        required to fund additional draws and are protected by structural tests 
        for spread accounts and early amortization.  ANPR:
 The Agencies are also seeking views on the proposed approach to 
        defining the risk inputs for the retail A-IRB framework. Is the proposed 
        degree offlexibility in their calculation, including the application 
        ofspecific floors, appropriate? What are views on the issues associated 
        with undrawn retail lines of credit described here and on the proposed 
        incorporation ofFMI in the QRE capital determination process?
 ONE:
 The proposal requires estimates of probability of default (PD) and 
        loss given default (LGD) independently, while the industry manages 
        exposure based on expected loss (EL) alone. The rules covering retail 
        assets are derived largely from the proposed commercial framework and 
        are not consistent with industry risk management practice. Bank One can 
        certainly calculate PDs, LGDs, and EAD for each of our product segments, 
        the exercise would be merely to fulfill regulatory capital requirements 
        and would add little value to the way we manage the risk of these 
        exposures.
 While a PD / LGD foundation is sound for commercial assets where 
        severity is observable on a transaction-by-transaction basis, the 
        framework does not apply well to retail assets. Retail assets typically 
        are managed on a pool basis where there is often a high correlation between the value of the underlying collateral and a 
        borrower's probability of default, making it difficult to separate 
        objectively losses into the components of frequency and severity. 
        Because of the link between PD and LGD, the industry measures and 
        manages risk based on portfolio EL and the volatility around it.  As currently written, the PD / LGD framework provides a potential 
        capital arbitrage based on a firm's definition of default. Since EL is 
        the product of PD and LGD, various combinations of the two parameters 
        are possible for the same EL. The capital requirement for each 
        combination is different, implying volatility around PD and LGD behave 
        differently. While this may be true, analysis to separate PD and LGD 
        behavior can be quite subjective and adds little value to current 
        practice. Accordingly, the retail industry does not measure PD and LGD 
        volatility separately, or the correlation between the two.  ANPR:
 The Agencies also seek comment on the competitive implications of 
        allowing PMI recognition for banking organizations using the A-IRB 
        approach but not allowing such recognition for general banks. In 
        addition, the Agencies are interested in data on the relationship 
        between PMI and LGD to help assess whether it may be appropriate to 
        exclude residential mortgages covered by PMI from the proposed 10 
        percent LGD floor. The Agencies request comment on whether or the extent 
        to which it might be appropriate to recognize PMI in LGD estimates.
 ONE:
 PMI is used as a prudent risk mitigation tool and should be 
        recognized as such. Most PMI providers are `AA' and `AAA'- rated 
        companies. We suggest that the LGD should be permitted to go below 10% 
        so long as the through-the-cycle historical data suggests it is 
        appropriate. In other words, the 10% LGD floor is arbitrary and 
        specifically inappropriate for low loan-to-value loans and loans covered 
        by PMI.
 Credit Risk Mitigation  ANPR:  Industry comment is sought on whether a more uniform method of 
        adjusting PD or LGD estimates should be adopted for various types of 
        guarantees to minimize inconsistencies in treatment across institutions 
        and, if so, views on what methods would best reflect industry practices. 
        In this regard, the Agencies would be particularly interested in 
        information on how banking organizations are currently treating various 
        forms of guarantees within their economic capital allocation systems and 
        the methods used to adjust PD, LGD, EAD, and any combination thereof.
          ONE:  The banking industry continues to struggle with the issue of joint 
        probability of default. It is particularly difficult to accurately 
        assess the correlation between individual (potentially related) 
        obligors. For guarantees we resort a `look through' approach on 100% 
        guarantees and a collateral adjustment for partial guarantees. Bank One 
        treats all 100% guarantees as impacting the PD and less than 100% 
        guarantees as factors used for the determination of LGD. In assigning 
        obligor ratings to a customer, credits that are 100%guaranteed are 
        assigned based on the financial condition of the guarantor  While this approach is consistent with ANPR's proposed treatment of 
        guarantees, we are concerned with a potential data capture requirement 
        stated in the ANPR. Under the Guarantees and Credit Derivative section, 
        the ANPR stated that, "The banking organization would be required to 
        assign the borrower and guarantor to an internal rating in accordance 
        with the minimum requirements set out for unguaranteed (unhedged) 
        exposures, both prior to adjustments and on an ongoing basis." We 
        question the need for an independent obligor rating absent the guarantee 
        and suggest that this statement be eliminated from the final rules.  Securitization   ANPR:  The Agencies seek comment on the proposed treatment of securitization 
        exposures under the RBA. For rated securitization exposures, is it 
        appropriate to differentiate risk weights based on tranche thickness and 
        pool granularity?   ONE:
 Calibration of RBA risk weights under the current proposal is based 
        on the Peretyatkin / Perraudin study* using a constant LGD of 50% 
        regardless of tranche thickness. While this may be appropriate for thin 
        mezzanine tranches, senior thick tranches demonstrate much lower LGD. 
        Appendix A of the American Securitization Forum ANPR response letter 
        dated November 3, 2003 contains a detailed study that shows that LGD 
        ranges from five to ten percent for thick tranches rated `A' or better. 
        This is true across a variety of asset classes including auto loans, 
        home equities and CDOs. RBA Risk weights for senior thick tranches 
        should be calibrated using the Perraudin and Peretyatkin model and the 
        lower LGD assumption.
 * Capital for Asset-Backed Securities, February 2003 by Vladislav 
        Peretyatkin and William Perraudin. A paper prepared for the 
        Securitization Sub-Group of the Basel Committee  ANPR:  The Agencies seek comment on the proposed methods for calculating 
        dilution risk capital requirements. Does this methodology produce 
        capital charges for dilution risk that seem reasonable in light of 
        available historical evidence? Is the corporate A-IRB capital formula 
        appropriate for computing capital charges for dilution risk?   In particular, is it reasonable to attribute the same asset 
        correlations to dilution risk as are used in quantifying the credit 
        risks of corporate exposures within the A-IRB framework? Are there 
        alternative method(s) for determining capital charges for dilution risk 
        that would be superior to that set forth above?   ONE:
 As proposed under the SFA approach, the inclusion of dilution in the 
        combined exposure fails to recognize recourse to the seller of the 
        receivables for the amount of dilution. When recourse is present, the 
        expected dilution amount is actually an unsecured loan to the seller. We 
        propose that regulatory capital requirements for this exposure be based 
        on the seller's PD and an unsecured LGD using the commercial risk weight 
        function. Dilution risk capital should be added to the results of the 
        SFA calculated for credit risk alone.
 Supervisory Standards   ANPR:  The Agencies also seek comment on the supervisory standards contained 
        in the draft guidance. Do the standards cover all of the key elements of 
        an A-IRB framework? Are there specific practices that appear to meet the 
        objectives of accurate and consistent ratings but that would be ruled 
        out by the supervisory standards related to controls and oversight? Are 
        there particular elements from the corporate guidance that should be 
        modified or reconsidered as the Agencies draft guidance for other types 
        of credit?   ONE:
 Bank One anticipates that historical data tracking will be a 
        particular challenge in regards to certain data elements and suggest 
        that the agencies be flexible in their requirements. For example, the 
        exact source of a recovery may not always be determinable, especially in 
        instances when pools of assets are being liquidated. Bank One also 
        suggests that language be modified to allow for the possibility of 
        certain missing data elements.
 Operational Framework   ANPR:  Does the broad structure that the Agencies have outlined incorporate 
        all the key elements that should be factored into the operational risk 
        framework for regulatory capital? If not, what other issues should be 
        addressed? Are any elements included not directly relevant for 
        operational risk measurement or management? The Agencies have not 
        included indirect losses (for example, opportunity costs) in the 
        definition of operational risk against which institutions would have to 
        hold capital; because such losses can be substantial, should they be 
        included in the definition of operational risk?   ONE:
 It will be difficult for institutions to demonstrate that explicit 
        and imbedded dependence (correlation) assumptions are appropriate as 
        insufficient data will be available to statistically validate these 
        assumptions across business lines and event types. Correlations likely 
        will be determined from qualitative reasoning based on the underlying 
        nature of the risks, and the proposal should recognize that qualitative 
        judgment will be necessary. Overly conservative criteria should not be 
        applied to correlation assumptions to avoid penalizing banks that use 
        more risk-sensitive "bottoms-up" approaches.
 ANPR:
 The Agencies seek comment on the extent to which an appropriate 
        balance has been struck between flexibility and comparability for the 
        operational risk requirement. If this balance is not appropriate, what 
        are the specific areas of imbalance and what is the potential impact of 
        the identified imbalance?
 ONE:
 Current supervisory practice around information requests is largely 
        unconstrained. First, given the broad implementation of an operational 
        risk management framework, compliance with vague information requests is 
        expensive. Second, specific reports from control self-assessments that 
        detail areas for improvement are likely to be frank when the reports are 
        used internally, but more guarded if regulators and supervisors are 
        allowed detailed access. The analysis and reporting of near misses, 
        potential legal liabilities and opportunity costs raise similar 
        concerns.
 ANPR:
 The Agencies are introducing the concept of an operational risk 
        management function, while emphasizing the importance of the roles 
        played by the board, management, lines of business, and audit. Are the 
        responsibilities delineated for each of these functions sufficiently 
        clear and would they result in a satisfactory process for managing the 
        operational risk framework?
 ONE:  The ANPR requires Board of Director approvals in their oversight and 
        approval of operational risk management frameworks and quantification. 
        Senior management typically provides oversight and approvals for the 
        development and implementation of risk management frameworks (credit, 
        market and operational) with updates provided periodically to the Board. 
        Banks should not be required to do something different under Basel II 
        requirements. The adequacy of corporate governance should be evaluated 
        as a Pillar II concept.  The roles of the Fed, OCC, FDIC, NASD and SEC overlap in the 
        supervision of operational risk management and should be further 
        clarified. It is important that the roles and responsibilities of the 
        various US supervisory bodies be delineated prior to the finalization of 
        operational risk supervisory guidance.  In addition, the ANPR overlaps other supervisory guidance such as 
        FDICIA and Sarbanes-Oxley. Different regulations should not only be 
        drafted for consistency, but also be explicitly evaluated for 
        contradictions. We urge the Supervisors to consider ways to take 
        advantage of these overlaps to reduce the overall regulatory burden of 
        these regulations.  ANPR:
 The Agencies seek comment on the reasonableness of the criteria for 
        recognition of risk mitggants in reducing an institution's operational 
        risk exposure. In particular, do the criteria allow for recognition of 
        common insurance policies? If not, what criteria is most binding against 
        current insurance products? Other than insurance, are there additional 
        risk mitigation products that should be considered for operational risk?
 ONE:
 The 20% ceiling on the amount of capital that can be offset by 
        insurance appears to be adequate until banks are able to demonstrate 
        that the number should be higher. Also insurance provided by captive 
        insurers should be allowed as a capital adjustment provided qualitative 
        criteria are met. The regulations should provide flexibility in allowing 
        recognition of other risk mitigation products that emerge in the future.
 Disclosure Requirements   ANPR:  The Agencies seek comment on the feasibility of such an approach to 
        the disclosure of pertinent information and also whether commenters have 
        any other suggestions regarding how best to present the required 
        disclosures.   Comments are requested on whether the Agencies' description of the 
        required formal disclosure policy is adequate, or whether additional 
        guidance would be useful. Comments are requested regarding whether any 
        of the information sought by the Agencies to be disclosed raises any 
        particular concerns regarding the disclosure of proprietary or 
        confidential information. If a commenter believes certain of the 
        required information would be proprietary or confidential, the Agencies 
        seek comment on why that is so and alternatives that would meet the 
        objectives of the required disclosure. The Agencies also seek comment 
        regarding the most efficient means for institutions to meet the 
        disclosure requirements. Specifically, the Agencies are interested in 
        comments about the feasibility of requiring institutions to provide all 
        requested information in one location and also whether commenters have 
        other suggestions on how to ensure that the requested information is 
        readily available to market participants.   ONE:
 The semi-annual reporting frequency set out in this proposal is 
        inconsistent with current reporting requirements and practices. We 
        recommend that a full disclosure be required on an annual basis, with 
        key changes highlighted quarterly. This reporting schedule would better 
        align with current disclosure requirements and would reduce the cost and 
        burden of compliance. Also, the United States already mandates board 
        oversight of financial disclosure, so a policy dictating governance and 
        compliance is unnecessary and would prove inflexible in light of ongoing 
        advancement in public reporting.
 We agree with the Committee's inclusion of a disclosure exemption for 
        proprietary and confidential information. In addition to the instances 
        cited in the draft, some of the details mandated by the disclosure 
        requirements may inadvertently result in customer information being 
        divulged, leading to privacy issues. This may be particularly true with 
        the requirement for industry data, from which customer information could 
        be distilled. As far as credit risk is concerned, disclosing any 
        geographic, industry, credit grade or other portfolio segmentation will 
        lead to inappropriate conclusions, and these alone do not define 
        portfolio risk. Proper use of the data requires an understanding of the 
        interrelationship between individual segments and the portfolio in 
        total, especially if comparisons across institutions are to be made. We 
        encourage a broadening of the exemption to additional circumstances as 
        warranted.
