1. This guidance supplements
the final rule published jointly by the U.S. federal banking agencies
1 in the
Federal Register on December 7, 2007 (advanced approaches rule).
2 The advanced approaches rule implements a
new risk-based capital framework encompassing three pillars:
- minimum risk-based capital requirements (Pillar 1),
- supervisory review (Pillar 2), and
- market discipline through enhanced public disclosures
(Pillar 3).
The minimum risk-based capital requirements
in Pillar 1 of the advanced approaches rule apply to a bank’s calculation
of minimum risk-based capital requirements for credit risk and operational
risk.
3 If the bank
is also subject to the market risk rule,
4 then the minimum risk-based capital requirements
in that rule would apply.
5 2. This document addresses
the process for supervisory review in the advanced approaches rule.
As described in this guidance, supervisory review covers three main
areas:
- comprehensive supervisory review of capital adequacy,
- compliance with regulatory capital requirements,
and
- internal capital adequacy assessment process (ICAAP).
3. The process of supervisory review described
in this guidance reflects a continuation of the longstanding approach
employed by the agencies in their supervision of banks. However, because
implementation of the advanced approaches rule affects certain
aspects of supervisory review, this guidance highlights areas of existing
supervisory review that are being augmented or more clearly defined
to support
implementation of the advanced approaches rule by U.S. banks.
4. The supervisory review process described in this document
is intended to help ensure overall capital adequacy by
- confirming a bank’s compliance with regulatory capital
requirements;
- addressing the limitations of minimum risk-based
capital requirements as a measure of a bank’s full risk profile—including
risks not covered or not adequately addressed or quantified in Pillar
1;
- ensuring that each bank is able to assess its own
capital adequacy (beyond minimum risk-based capital requirements)
based on its risk profile and business model; and
- encouraging banks to develop and use better techniques
to identify and measure risk.
5. This guidance neither supersedes nor alters
the functioning of the existing prompt corrective action requirements.
6 Similarly, this
guidance does not affect any other requirements for compliance with
existing regulations and supervisory standards related to risk-management
practices or other areas. The supervisory review process described
in this guidance supports the supervisors’ existing ability to
- require an individual bank to take measures to prevent
its capital from falling below the level needed to adequately support
its risks, or
- otherwise intervene to ensure that the bank’s capital
levels are adequate.
Comprehensive Supervisory Review
of Capital Adequacy6. Capital helps protect
individual banks from insolvency, thereby promoting safety and soundness
in the overall U.S. banking system. Minimum risk-based capital requirements
establish a threshold below which a sound bank’s risk-based capital
must not fall. Risk-based capital ratios permit some comparative analysis
of capital adequacy across banks because they are based on certain
common assumptions. However, supervisors must perform a more comprehensive
review of capital adequacy that considers the risks that are specific
to each individual bank, including those not incorporated in risk-based
capital requirements. In short, supervisors must ensure that a bank’s
overall capital does not fall below the level required to support
its entire risk profile.
7. Supervisors generally
expect banks to hold capital above their minimum risk-based capital
levels, commensurate with their individual risk profiles, to account
for all material risks. Going forward under the advanced approaches
rule, supervisors will continue to review the overall capital adequacy
of any bank through a comprehensive evaluation that considers all
relevant available information. In determining the extent to which
banks should hold capital in excess of risk-based capital minimums,
supervisors will consider: the combined implications of a bank’s compliance
with qualification requirements for regulatory capital standards;
the quality and results of a bank’s own process for determining whether
capital is adequate (the ICAAP); and the bank’s risk-management processes,
control structure, and other relevant information relating to the
bank’s risk profile and capital level.
7 This review is consistent with current supervisory practice,
under which the agencies assess a bank’s overall capital adequacy
through a comprehensive evaluation of all relevant information.
8. The supervisory review process assesses whether
a bank has a satisfactory process to determine that its overall capital
is adequate and that the bank maintains adequate capital on an ongoing
basis as underlying conditions change. For example, changes in a bank’s
risk profile or in relevant capital measures are areas of particular
focus that are effectively addressed through the supervisory review
process. Generally, a bank should hold more capital for material increases
in risk that are not otherwise mitigated, unless the bank already holds capital
at a level exceeding what its internal processes and supervisors would
regard as adequate. Conversely, a bank may be able to reduce overall
capital (to a level still above regulatory minimums) if the supervisory
review supports the conclusion that the bank’s inherent risk has materially
declined or that it has been appropriately mitigated.
9. As a result of its comprehensive supervisory review,
a bank’s primary federal supervisor may take action if it is not satisfied
that capital is adequate. The primary federal supervisor may require
the bank to take actions to address identified supervisory concerns,
which may include requiring the bank to hold additional capital to
bring capital to levels that the supervisor deems commensurate with
the bank’s risk profile. In addition, the primary federal supervisor
may, under its enforcement authority, require a bank to modify or
enhance risk-management and internal-control processes, reduce its
exposure to risk, or take any action deemed necessary to address identified
supervisory concerns.
Compliance
with Regulatory Capital Requirements 10.
In order to use the advanced approaches rule to calculate minimum
risk-based capital requirements, a bank must meet certain process
and systems requirements. As part of the supervisory review process,
the agencies will ensure that each bank meets these requirements.
The advanced approaches rule provides an explanation of these qualification
requirements for any systems and processes used.
11. A bank using the advanced approaches rule must comply with the
rule’s qualification requirements for both initial and ongoing qualification.
A bank that falls out of compliance with the qualification requirements
would be required to establish a plan to return to compliance that
satisfies its primary federal supervisor.
12.
Supervisors will ensure that each bank using the advanced approaches
rule complies with the qualification requirements both at the consolidated
level and at any subsidiary bank that uses the advanced approaches
rule. Thus, each bank that applies the advanced approaches rule must
have appropriate risk-measurement and risk-management processes and
systems that meet the rule’s qualification requirements.
The ICAAP 13. The qualification
requirements in the advanced approaches rule state that “a bank must
have a rigorous process for assessing its overall capital adequacy
in relation to its risk profile and a comprehensive strategy for maintaining
an appropriate level of capital.”
8 Because minimum risk-based capital requirements are based on certain
assumptions and address only a subset of risks faced by an individual
bank, each bank must conduct an internal assessment of whether its
capital is adequate, given its risk profile. A bank must conduct this
assessment, using the ICAAP, in addition to its calculation of minimum
risk-based capital requirements.
9
Accordingly, a bank’s capital should exceed the level
required by its minimum risk-based capital requirements, and also
should be adequate according to its own ICAAP.
14. The fundamental objectives of a sound ICAAP are
- identifying and measuring material risks,
- setting and assessing internal capital adequacy goals
that relate directly to risk, and
- ensuring the integrity of internal capital adequacy
assessments.
15. Assessing overall capital adequacy through
the ICAAP requires thorough identification of all material risks,
measurement of those that can be reliably quantified, and systematic assessment
for the limitations of minimum risk-based capital requirements. The
ICAAP should address the capital implications arising from both on-
and off-balance-sheet positions, as well as from provisions of explicit
or implicit support. Material risks include those that in isolation
do not appear to be material at first, but when combined with other
risks could lead to material losses. In this manner, the ICAAP should
contribute broadly to the development of better risk management within
the organization at both the individual entity and consolidated levels.
16. Each bank implementing the advanced approaches
rule should have an ICAAP that is appropriate for its unique risk
characteristics and should not rely solely upon the assessment of
capital adequacy at the parent company level. This does not preclude
the use of a consolidated ICAAP as an important input to a subsidiary
bank’s own ICAAP, provided that each entity’s board and senior management
ensure that the ICAAP is appropriately modified to address the unique
structural and operating characteristics and risks of the subsidiary
bank.
17. In general, the ICAAP will likely go
beyond the assumptions built into minimum risk-based capital requirements.
However, in certain instances, a bank’s ICAAP—when supported by proper
justification and evidence—may build upon and utilize the methods,
practices, and results it uses to determine minimum risk-based capital
requirements. For example, in developing the ICAAP, a bank may choose
to use data, ratings, or estimates from internal ratings-based approaches
for credit risk; or a bank may choose to use the advanced measurement
approaches as the basis for its internal assessment of operational
risk. Furthermore, although the ICAAP should be a distinct and comprehensive
process that produces its own capital measures, in some cases a bank
may be able to demonstrate that minimum risk-based capital measures
appropriately reflect certain aspects of a bank’s risk profile and
thus are appropriate for use in its ICAAP.
18.
The design and operation of any systems used to meet the ICAAP requirements
will likely differ, depending on the complexity of each bank’s operations
and risk profile. Many banks employ “economic capital” measures for
some elements of risk management, such as limit setting, or for evaluating
performance or determining aggregate capital needs.
10 In some cases, economic
capital measures may relate directly to a bank’s assessment of capital
adequacy under the ICAAP; however, in other cases, a bank may be using
economic capital measures that are not intended for capital adequacy
assessments. In the latter case, a bank does not necessarily need
to change its existing process or systems, but it may need to build
upon or adjust its economic capital measures for use in the ICAAP,
and the bank would have to demonstrate clearly how it does so. Notably,
economic capital is not the only means to meet the ICAAP requirement.
Regardless of the specific implementation method(s) chosen, the bank’s
ICAAP should address the three ICAAP objectives listed in paragraph.
Identifying and Measuring Material
Risks 19. The first objective of the
ICAAP is to identify all material risks. Risks that can be reliably
measured and quantified should be treated as rigorously as data and
methods allow. The appropriate means and methods to measure and quantify
those material risks are likely to vary across banks. The key point
is for a bank to be able to identify all material risks and measure
those that can be reliably quantified in order to determine how those
risks affect the bank’s overall capital adequacy.
20. Some of the risks to which a bank may be exposed include credit
risk, market risk, operational risk, interest-rate risk in the banking
book, and liquidity risk (as outlined be
low).
11 Other risks, such as reputational risk, business
or strategic risk, and country risk, may also be material for a bank
and, in such cases, should be given equal consideration to the more
formally defined risk types.
12 Additionally,
if a bank employs risk-mitigation techniques, it should understand
the risk to be mitigated and the potential effects of that mitigation
(including enforceability and effectiveness).
Credit risk: A bank should have the
ability to assess credit risk at the portfolio level in addition to
the exposure or counterparty level. In making this assessment, the
bank should be particularly attentive to identifying any credit risk
concentrations and ensuring that their effects are adequately assessed.
The bank should consider the various types of dependence among exposures,
and the credit-risk effects of extreme outcomes, stress events, and
shocks to assumptions about portfolio and exposure behavior. The bank
should also carefully assess concentrations in counterparty credit
exposures, including those that result from trading in less liquid
markets, and determine the effect that these exposures might have
on capital adequacy.
Market risk: A bank should be able to identify risks in trading
and capital markets activities resulting from a movement in market
prices and rates. This determination should consider factors such
as illiquidity of instruments, leverage, concentrated positions, one-way
markets, non-linear or deep out-of-the money option positions as well
as embedded optionality, and the potential for significant shifts
in correlations or other types of dependence structures. Assessments
that incorporate extreme events, idiosyncratic variations, credit
migrations or changes in credit spreads, defaults, and shocks should
also be tailored to capture key portfolio vulnerabilities.
Operational risk: A bank
should be able to assess the potential risks resulting from inadequate
or failed internal processes, people, and systems, as well as from
events external to the bank.
13 This assessment should include
the effects of extreme events and shocks relating to operational risk.
Extreme events could include a substantial or sudden increase in failed
processes across business units or a significant incidence of failed
internal controls.
Interest-rate
risk in the banking book: A bank should incorporate interest-rate
risk in the banking book into its assessment of capital adequacy.
In making this assessment, the bank should identify the risks associated
with changes in interest rates that impact both on- and off-balance-sheet
exposures in the banking book from a short- and long-term perspective.
This might include the impact of changes due to parallel yield curve
shocks, yield curve twists, yield curve inversions, changes in the
adjustment of rates earned and paid on different financial instruments
with otherwise similar repricing characteristics (basis risk), and
other relevant scenarios, including some that incorporate stress events,
extreme outcomes, and shocks to assumptions. The bank should be able
to support any assumptions it has made with respect to the behavioral
characteristics of servicing rights, non-maturity deposits, positions
subject to prepayment risk, and other assets and liabilities, especially
for those exposures characterized by embedded optionality.
Liquidity risk: A bank
should incorporate liquidity risk into the assessment of its capital
adequacy. A bank should evaluate whether capital is adequate given
its own funding liquidity profile and given the liquidity of the markets
in which it operates. This assessment should incorporate various types
of liquidity environments and include an evaluation of the potential for
a material disruption in the sources of liquidity typically relied
on by the bank as a result of bank-specific as well as systemic events.
A bank should consider the capital adequacy implications of lacking
a well-diversified funding base, relying predominantly on wholesale
credit markets for its funding, or relying heavily on volatile funding
sources. A bank involved in securitization activities should consider
the capital adequacy implications of relying on market liquidity to
distribute warehoused assets, including the potential for disruptions
that would cause a bank to bring certain items onto its balance sheet.
In its assessment of the impact of liquidity risk on capital adequacy,
the bank should also challenge assumptions built into its definition
of liquid products.
The risk factors discussed above are not an exhaustive
list of those affecting any given bank. A well-developed ICAAP should
include an assessment of all relevant factors that present a material
source of risk to capital and should account for concentrations within
each risk type.
21. A bank should assess whether
its capital is sufficient to absorb any losses that may arise from
activities that expose the bank to multiple risks within and across
business lines or create concentrations across risk types.
14 A bank should
recognize that losses could arise in several risk dimensions at the
same time, stemming from the same event or a common set of factors.
For example, a localized natural disaster could generate losses from
credit, market, and operational risks. Additionally, the ICAAP should
focus on any complex activities that give rise to multiple risks,
and to their interaction. These activities can involve instruments
that may be complex, illiquid, or difficult to value. For example,
securitization activities expose a bank to a variety of risks that
can affect capital adequacy at the same time, including credit, market,
liquidity, and reputational risks; structured products can have multiple
embedded risks that interact in complex ways and can present losses
in multiple risk areas across different business lines at the same
time. In general, the ICAAP should include an assessment of the potential
effects of convergence of risks within and across business lines and
their combined impact on capital adequacy.
22.
The ICAAP should take into consideration the linkage between capital
adequacy and damage or potential damage to a bank’s reputation. A
bank might incur losses affecting capital adequacy because of damage
to its reputation, or the bank might incur losses trying to prevent
or mitigate damage to its reputation. In assessing the linkage between
reputational risk and capital adequacy, a bank should assess risks
associated with both on-balance-sheet and off-balance-sheet exposures
and activities, as well as risks associated with affiliates, subsidiaries,
counterparties, clients, or other third parties. The assessment should
include activities for which the bank acts as a sponsor or advisor
and cases in which the bank provides explicit or implicit support.
A bank should also assess the risk of having to assume the losses
of a third party to prevent or mitigate damage to the bank’s reputation.
23. The bank’s ICAAP should assess risks associated
with new products, markets, and activities. In making this assessment,
the bank should account for any uncertainty in the valuation of new
products, whether by the bank or a third party, which could be more
challenging if the new products are particularly complex or do not
have liquid markets. The ICAAP should take into consideration changing
dynamics in markets for new products and uncertainty as to how new
markets might respond to stress conditions. The ICAAP should also
assess the challenges presented by new business lines or strategic
acquisitions in terms of their impact on capital adequacy.
24. All measurements of risk should incorporate both
quantitative and qualitative elements. Generally, a quantitative approach
should form the foundation of a bank’s measurement framework.
Quantitative approaches that focus on most likely outcomes for budgeting,
forecasting, or performance measurement purposes may not be fully
applicable for assessing capital adequacy, which also should take
less likely outcomes into account.
25. In some
cases, quantitative tools can include the use of large historical
databases. These databases are most applicable when they are fully
reflective of all relevant risk characteristics, incorporate appropriate
variability, and have adequate granularity and history; for example,
they should include data-based not just on benign but also more-stressful
economic periods or operating environments. When internal data are
not available or do not reflect a bank’s risk profile, a bank may
rely on external data for risk measurements but should ensure that
external data have applicability to the bank’s own activities and
risk profile.
26. The confidence a bank places
in the results of its ICAAP should depend on the quality and robustness
of the associated risk assessments. When measuring risks, a bank should
understand that estimation and measurement errors are common and,
in many cases, are themselves difficult to quantify. In general, the
bank’s ICAAP should reflect an appropriate level of conservatism to
account for uncertainty in risk identification, risk mitigation or
control, and risk quantification. In most cases, appropriate conservatism
will result in greater capital needs.
27. In many
cases, risk assessments may rely to a significant degree on models
that use both qualitative and quantitative inputs. The use of models
can enhance the ICAAP, but it can also introduce challenges. Specifically,
models may fail to work as intended or expected, or they may be used
inappropriately for purposes not considered in their initial design.
These concerns apply to models purchased from third-party vendors
as well as to models that are internally developed. A bank using models
as part of the ICAAP should recognize these possibilities and ensure
that appropriate controls, such as rigorous initial and ongoing validation
and independent review, are in place to mitigate and manage any risks
related to model use. A bank should apply appropriate conservatism
to compensate for any risks associated with models. Additional conservatism
may be necessary to account for any uncertainties in the use of models
to value on- or off-balance-sheet exposures or for imperfections and
volatility in market-based valuations.
Additional conservatism may be necessary to compensate
for increased risk, for example, when models or applications are more
complex, or when they have a more significant influence on the ICAAP’s
results.
28. To gain a fuller understanding of
the risks beyond more-typical quantitative measures—such as those
based on certain parameter behavior or distributional assumptions—a
bank should also rely on other types of quantitative exercises. For
example, stress testing, including scenario analysis and sensitivity
analysis, is an additional quantitative exercise that a bank should
regularly apply to complement more-typical quantitative measures.
A bank may need to rely more heavily on such exercises when internal
or demonstrably relevant external data are scarce. These exercises
can help gauge the consequences of outcomes that are unlikely, but
would have a considerable impact on safety and soundness.
29. In addition to quantitative approaches for assessing
risk, a bank should also employ qualitative approaches that incorporate
management experience and judgment. Qualitative measures should be
employed not only for those cases in which scarce data or unproven
quantitative methods limit a full assessment of risk, but also more
generally to complement even sophisticated quantitative estimates
based on extensive and high-quality data.
30.
A bank should be cognizant that both quantitative and qualitative
approaches have their own inherent biases and assumptions that affect
risk assessment. Accordingly, a bank should recognize the biases and
assumptions embedded in, and the limitations of, the approaches used.
31. An effective ICAAP is comprehensive, assessing material
risks across the entire bank. Each bank should have systems capable
of aggregating across risk types. A bank should understand the challenges
presented by risk aggregation and the inherent uncertainty in quantitative
estimates used to aggregate risks (including the difficulty in estimating
concentrations across risk types as noted in paragraph 21). For example,
a bank is encouraged to consider the various interdependencies among
risk types, the different techniques used to identify such interdependencies,
and the channels through which those interdependencies might arise—across
risk types, within the same business line, and across different business
lines. Consistent with paragraph 26, any associated uncertainty in
aggregating capital estimates across risk types and business lines
should translate into greater capital needs.
32.
Management should be systematic and rigorous in considering possible
effects of diversification. Assumptions about diversification should
be identified at each level where diversification is recognized, supported
by analysis and evidence, and remain robust over time and under different
market environments, including stressed market conditions. For example,
a bank calculating the dependence structure within or among risk types
should consider data quality and consistency, such as the volatility
of correlations over time and during periods of market stress. In
general, a bank should consider a wide range of possible adverse outcomes
that have the potential to affect multiple risks at the same time
and to limit expected diversification benefits. Consistent with paragraph
26, uncertainty in diversification estimates should translate into
greater capital needs.
Setting
and Assessing Capital Adequacy Goals that Relate to Risk 33. The second objective of the ICAAP is to set and
assess capital adequacy goals in relation to all material risks. Under
this objective, a bank should have a well-defined process to translate
estimates of risk into an assessment of capital adequacy. In practice,
capital adequacy goals may be reflected in various ways. A bank may
choose to hold capital in excess of the level internal processes would
regard as adequate for any number of business or strategic reasons.
Excess capital may fluctuate over time. Each bank should recognize
that minimum risk-based capital requirements represent a floor below
which the bank’s overall capital level must not fall, even if bank
management believes that there is justification to maintain less capital.
34. A bank may establish its risk-tolerance level
to reflect a desired level of risk coverage and/or a certain degree
of creditworthiness, such as an explicit solvency standard. Accordingly,
assessments of risk and capital adequacy should reflect the chosen
risk tolerance of the bank. Because risk profiles and choices of risk
tolerance may differ across banks, capital targets may also differ.
However, if for internal capital adequacy purposes a bank were to
choose to apply a level of risk coverage or a solvency standard that
is less than that implied by minimum risk-based capital requirements,
the bank would have to be able to: identify and support the rationale
for a lower solvency standard; demonstrate clearly that its ICAAP
adequately addresses low-probability, high-severity events; and ensure
that there is sufficient capital to absorb losses associated with
such extreme events. Regardless of the solvency standard used, supervisors
expect banks to hold capital at a level above that established by
minimum risk-based capital requirements.
35. A
bank should consider external conditions and other factors that influence
its overall capital adequacy, including the potential impact of contingent
exposures and changing economic and financial environments. The ICAAP
should address the potential impact of broader market or systemic
events, which could cause risk to increase beyond the bank’s chosen
risk-tolerance level, and have appropriate contingency plans for such
outcomes. Such exercises may include stress testing, such as scenario
and sensitivity analysis; how
ever, in all cases they should incorporate both
quantitative and qualitative methods.
15 36. Through the ICAAP,
a bank should ensure that adequate capital is held against all material
risks and that capital remains adequate not just at a point in time,
but over time, to account for changes in a bank’s strategic direction,
evolving economic conditions, and volatility in the financial environment.
A bank should be cognizant of the impact of market-driven valuations
on the volatility of capital. Moreover, recognizing the sensitivity
of capital to economic and financial cycles should be a critical component
of a bank’s planning for current and future capital needs. For example,
a bank should consider the potential effects of a sudden, sustained
economic downturn. The level of capital deemed adequate by a bank
given its ICAAP might also be influenced by the bank’s intention to
hold additional capital to mitigate the impact of volatility in capital
requirements, its need to support acquisition plans, or its decision
to accommodate market perceptions of capital adequacy and their impact
on funding costs.
37. In analyzing capital adequacy,
a bank should evaluate the capacity of its capital to absorb losses.
Because various definitions of capital are used within the banking
industry, each bank should state clearly the definition of capital
used in any aspect of its ICAAP. Since components of capital are not
necessarily alike and have varying capacities to absorb losses, a
bank should be able to demonstrate the relationship between its internal
capital definition and its assessment of capital adequacy. If a bank’s
definition of capital differs from the regulatory definition, the
bank should reconcile such differences and provide an analysis to
support the inclusion of any capital instruments that are not recognized
under the regulatory definition. Although common equity is generally
the predominant component of a bank’s capital structure, a bank may
be able to support the inclusion of other capital instruments in its
internal definition of capital if it can demonstrate a similar capacity
to absorb losses. The bank should document any changes in its internal
definition of capital, and the reason for those changes.
38. An effective capital plan recognizes a bank’s short-
and long-term capital needs and objectives. Accordingly, a bank should
evaluate whether long-run capital targets are consistent with short-run
goals, based on current and planned changes in risk profiles. In developing
its capital plan, the bank also should recognize that accommodating
additional capital needs can require significant lead time, can be
costly, or can be quite difficult, especially during downturns or
other times of stress. A bank should have contingency plans to address
unexpected capital needs.
Ensuring Integrity of Internal Capital Adequacy Assessments 39. A satisfactory ICAAP comprises a complete process
with proper oversight and controls, and not just an ability to carry
out certain capital calculations. The various elements of a bank’s
ICAAP should complement and reinforce one another to achieve the overall
objective of assessing capital adequacy, taking into account the bank’s
risk profile.
40. A bank should maintain adequate
internal controls to ensure the integrity, objectivity, and consistent
application of the ICAAP. Decisions regarding the design and operation
of the ICAAP should reflect sound risk management and should not be
unduly influenced by competing business objectives. A bank should
identify any deficiencies in its ICAAP and plan and take remedial
actions to address the deficiencies in a timely manner. The principles
underlying a bank’s ICAAP should be incorporated into policies that
are reviewed and approved at appropriate levels within the organization.
41. A bank should maintain thorough documentation
of its ICAAP to ensure transparency. At a minimum, this should include
a description of the bank’s overall capital management process, including
the committees and individuals responsible for the ICAAP; the frequency
and distribution of ICAAP-related reporting; and the procedures for
the periodic evaluation of the appropriateness and adequacy of the
ICAAP. In addition, where applicable, ICAAP documentation should demonstrate
the bank’s sound use of quantitative methods (including model selection
and limitations) and data-selection techniques, as well as appropriate
maintenance, controls, and validation. A bank should document and
explain the role of third-party and vendor products, services, and
information—including methodologies, model inputs, systems, data,
and ratings—and the extent to which they are used within the ICAAP.
A bank should have a process to regularly evaluate the performance
of third-party and vendor products, services, and information. As
part of the ICAAP documentation, a bank should document the assumptions,
methods, data, information, and judgment used in its quantitative
and qualitative approaches.
42. The ICAAP should
be enhanced and refined over time, with learning and experience (both
quantitative and qualitative) contributing to its improvement. The
ICAAP should evolve with changes in the risk profile and activities
of the bank, as well as with advances in risk-measurement and -management
practices. For example, a bank should incorporate in its ICAAP the
introduction of new products and business lines and activities to
ensure that the bank’s capital plan is responsive to changes in the
operational and/or business environment.
43. The
board of directors and senior management have certain responsibilities
in developing, implementing, and overseeing the ICAAP. The board should
approve the ICAAP and its components. The board or its appropriately
delegated agent should review the ICAAP and its components on a regular
basis and approve any revisions. That review should encompass the
effectiveness of the ICAAP, the appropriateness of risk tolerance
levels and capital planning, and the strength of control infrastructures.
Senior management should continually ensure that the ICAAP is functioning
effectively and as intended, under a formal review policy that is
explicit and well documented. Additionally, a bank’s internal audit
function should play a key role in reviewing the controls and governance
surrounding the ICAAP on an ongoing basis.
44.
Each bank should ensure that the components of its ICAAP, including
any models and their inputs, are subject to the bank’s validation
policies and procedures. Validation should be independent of the development,
implementation, and operation of the ICAAP components, or the validation
process should be subject to an independent review of its adequacy
and effectiveness. Validation is generally defined as an ongoing process
that includes, but is not limited to, the collection and review of
developmental evidence, process verification, benchmarking, outcomes
analysis, and monitoring activities used to confirm that processes
are operating as designed. Validation policies and procedures should
reflect the bank’s business, structure, and sophistication, as well
as the relative importance of each component of the ICAAP. Accordingly,
a bank is encouraged to consult the agencies’ existing guidance on
validation.
45. A bank’s ICAAP should be aligned
with and be a part of the bank’s wider internal governance structure
and overall risk-management processes. The ICAAP should not be viewed
as simply a compliance exercise. Rather, it is a dynamic and evolving
process that is used by a bank to provide internal assurance that
capital is adequate given the bank’s risk profile. Management is responsible
for ensuring that the ICAAP is fully consistent with the overall risk-management
framework of the bank. Information derived through the ICAAP process
should influence decision making at both the consolidated and individual
business-line levels, and be used to inform other management processes
related to risk assessment, business planning and forecasting, pricing
strategies, and performance measurement.
46. As part
of the ICAAP, the board or its delegated agent, as well as appropriate
senior management, should periodically review the resulting assessment
of overall capital adequacy. This review, which should occur at least
annually, should include an analysis of how measures of internal capital
adequacy compare with other capital measures (such as regulatory,
accounting-based or market-determined). Upon completion of this review,
the board or its delegated agent should determine that, consistent
with safety and soundness, the bank’s capital takes into account all
material risks and is appropriate for its risk profile. However, in
the event a capital deficiency is uncovered (that is, if capital is
not consistent with the bank’s risk profile or risk tolerance), management
should consult and adhere to formal procedures to correct the capital
deficiency.
