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

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.
