Activities: Capital Adequacy

Manual (pdf format) can be downloaded from the Federal Reserve's web
site)
As with all risk-bearing activities, the
risk exposures a banking organization assumes in its trading, derivative,
and capital-markets activities should be fully supported by an adequate
capital position. Accordingly, banking organizations should ensure that
their capital positions are sufficiently strong to support all trading
and capital-markets risks on a fully consolidated basis and that adequate
capital is maintained in all affiliated entities engaged in these activities.
Institutions with significant trading activities should have reasonable
methods to measure the risks of their activities and allocate capital
against the economic substance of those risks. To that extent, regulatory
capital requirements should be viewed as minimum requirements, and those
institutions exposed to a high or inordinate degree of risk or forms of
risk that may not be fully addressed in regulatory requirements are expected
to operate above minimum regulatory standards consistent with the economic
substance of the risks entailed.
As the baseline for capital-adequacy assessment, bank supervisors first
consider an organization's risk-based capital ratio; that is, the ratio
of qualifying capital to assets and off-balance-sheet items that have
been ''risk weighted'' according to perceived credit risk. Supervisors
also focus on the tier 1 leverage ratio to help assess capital adequacy.
For banking organizations with significant trading activities, the risk-based
capital ratio also takes into account an institution's exposure to market
risk.1
RISK-BASED CAPITAL MEASURE
The principal objectives of the risk-based
capital measure2
are to (1) make regulatory capital requirements generally sensitive to
differences in risk profiles among banking organizations; (2) factor off-balance-sheet
exposures into the assessment of capital adequacy; (3) minimize disincentives
to holding liquid, low-risk assets; and (4) achieve greater consistency
in the evaluation of the capital adequacy of major banks throughout the
world. The risk-based capital measure focuses primarily on the credit
risk associated with the nature of banking organizations' on- and off-balance-sheet
exposures and on the type and quality of their capital. It provides a
definition of capital and a framework for calculating risk-weighted assets
by assigning assets and off-balance-sheet items to broad categories of
credit risk. A banking organization's risk-based capital ratio is calculated
by dividing its qualifying capital by its risk-weighted assets. The risk-based
capital measure sets forth minimum supervisory capital standards that
apply to all banking organizations on a consolidated basis.
The risk-based capital ratio focuses principally on broad categories of
credit risk. For most banking organizations, the ratio does not incorporate
other risk factors that may affect the organization's financial condition.
These factors may include overall interest-rate exposure; liquidity, funding,
and market risks; the quality and level of earnings; investment or loan
portfolio concentrations; the effectiveness of loan and investment policies;
the quality of assets; and management's ability to monitor and control
financial and operating risks. An overall assessment of capital adequacy
must take into account these other factors and may differ significantly
from conclusions that might be drawn solely from the level of an organization's
risk-based capital ratio.
Definition of Capital
For risk-based capital purposes, a banking organization's capital consists
of two major components: core capital elements (tier 1 capital) and supplementary
capital elements (tier 2 capital). Core capital elements include common
equity including capital stock, surplus, and undivided profits; qualifying
non-cumulative perpetual preferred stock (or, for bank holding companies,
cumulative perpetual preferred stock, the aggregate of which may not exceed
25 percent of tier 1 capital); and minority interest in the equity accounts
of consolidated subsidiaries. Tier 1 capital is generally defined as the
sum of core capital elements less goodwill, unrealized holding losses
in the available-for-sale equity portfolio, and other intangible assets
that do not qualify within capital, as well as any other investments in
subsidiaries that the Federal Reserve determines should be deducted from
tier 1 capital. Tier 1 capital represents the highest form of capital,
namely permanent equity. Tier 2 capital consists of a limited amount of
the allowance for loan and lease losses, perpetual preferred stock that
does not qualify as tier 1 capital, mandatory convertible securities and
other hybrid capital instruments, long-term preferred stock with an original
term of 20 years or more, and limited amounts of term subordinated debt,
intermediate-term preferred stock, and unrealized holding gains on qualifying
equity securities. See section 3020.1, ''Assessment of Capital Adequacy,''
in the Commercial Bank Examination Manual for a complete definition of
capital elements.
Capital investments in unconsolidated banking and finance subsidiaries
and reciprocal holdings of other banking organizations' capital instruments
are deducted from an organization's capital. The sum of tier 1 and tier
2 capital less any deductions makes up total capital, which is the numerator
of the risk-based capital ratio.
In assessing an institution's capital adequacy, supervisors and examiners
should consider the capacity of the institution's paid-in equity and other
capital instruments to absorb economic losses. In this regard, it has
been the Federal Reserve's long-standing view that common equity (that
is, common stock and surplus and retained earnings) should be the dominant
component of a banking organization's capital structure and that organizations
should avoid undue reliance on non-common-equity capital elements.
3 Common equity allows an organization
to absorb losses on an ongoing basis and is permanently available for
this purpose. Further, this element of capital best allows organizations
to conserve resources when they are under stress because it provides full
discretion in the amount and timing of dividends and other distributions.
Consequently, common equity is the basis on which most market judgments
of capital adequacy are made.
Consideration of the capacity of an institution's capital structure to
absorb losses should also take into account how that structure could be
affected by changes in the institution's performance. For example, an
institution experiencing a net operating loss-perhaps because of realization
of unexpected losses-will face not only a reduction in its retained earnings,
but also possible constraints on its access to capital markets. These
constraints could be exacerbated should conversion options be exercised
to the detriment of the institution. A decrease in common equity, the
key element of tier 1 capital, may have further unfavorable implications
for an organization's regulatory capital position. The eligible amounts
of most types of tier 1 preferred stock and tier 2 or tier 3 capital elements
may be reduced, because current capital regulations limit the amount of
these elements that can be included in regulatory capital to a maximum
percentage of tier 1 capital. Such adverse magnification effects could
be further accentuated should adverse events take place at critical junctures
for raising or maintaining capital, for example, as limited-life capital
instruments are approaching maturity or as new capital instruments are
being issued.
Risk-Weighted Assets
Each asset and off-balance-sheet item is assigned to one of four broad
risk categories based on the obligor or, if relevant, the guarantor or
type of collateral. The risk categories are zero, 20, 50, and 100 percent.
The standard risk category, which includes the majority of items, is 100
percent. The appropriate dollar value of the amount in each category is
multiplied by the risk weight associated with that category. The weighted
values are added together and the resulting sum is the organization's
risk-weighted assets, the denominator of the risk-based capital ratio.4
Off-balance-sheet items are incorporated into the risk-based capital ratio
by first being converted into a ''credit-equivalent'' amount. To accomplish
this, the face amount of the item is multiplied by a credit conversion
factor (zero, 20, 50, or 100 percent). The credit-equivalent amount is
then assigned to a risk category in the same manner as on-balance-sheet
items. For over-the-counter derivative transactions, the credit-equivalent
amount is determined by multiplying the notional principal amount of the
underlying contract by a credit-conversion factor and adding the resulting
product (which is an estimate of potential future exposure) to the positive
mark-to-market value of the contract (which is the current exposure).
A contract with a negative mark-to-market value is treated as having a
current exposure of zero. (See ''Credit-Equivalent Computations for Derivative
Contracts'' below.)
The primary determinant of the appropriate risk category for a particular
off-balance-sheet item is the obligor. Collateral or guarantees may be
used to a limited extent to assign an item to a lower risk category than
would be available to the obligor. The forms of collateral generally recognized
for risk-based capital purposes are cash on deposit in the lending institution;
securities issued or guaranteed by central governments of the Organization
for Economic Cooperation and Development (OECD) countries,5
U.S. government agencies, or U.S. government-sponsored agencies; and securities
issued by multilateral lending institutions or regional development banks
in which the U.S. government is a shareholder or contributing member.
The only guarantees recognized are those provided by central or state
and local governments of the OECD countries, U.S. government agencies,
U.S. government-sponsored agencies, multilateral lending institutions
or regional development banks in which the United States is a shareholder
or contributing member, U.S. depository institutions, and foreign banks.
Banking organizations are expected to meet a minimum ratio of capital
to risk-weighted assets of 8 percent, with at least 4 percent taking the
form of tier 1 capital. Organizations that do not meet the minimum ratios,
or that are considered to lack sufficient capital to support their activities,
are expected to develop and implement capital plans acceptable to the
Federal Reserve for achieving adequate levels of capital.
TIER 1 LEVERAGE RATIO
The principal objective of the tier 1 leverage
measure is to place a constraint on the maximum degree to which a banking
organization can leverage its equity capital base.6
A banking organization's tier 1 leverage ratio is calculated by dividing
its tier 1 capital by its average total consolidated assets. Generally,
average total consolidated assets are defined as the quarterly average
total assets reported on the organization's most recent regulatory reports
of financial condition, less goodwill, certain other intangible assets,
investments in subsidiaries or associated companies, and certain excess
deferred-tax assets that are dependent on future taxable income.
The Federal Reserve has adopted a minimum tier 1 leverage ratio of 3 percent
for the most highly rated banks. A state member bank operating at or near
this level is expected to have well-diversified risk, including no undue
interest-rate-risk exposure; excellent asset quality; high liquidity;
good earnings; and in general be considered a strong banking organization
rated a composite 1 under the CAMELS rating system for banks. Other state
member banks are expected to have a minimum tier 1 leverage ratio of 4
percent. Bank holding companies rated a composite 1 under the BOPEC rating
system and those that have implemented the Board's risk-based capital
measure for market risk must maintain a minimum tier 1 leverage ratio
of 3 percent. Other bank holding companies are expected to have a minimum
tier 1 leverage ratio of 4 percent. In all cases, banking organizations
should hold capital commensurate with the level and nature of all risks
to which they are exposed.
1. The market-risk capital rules
are mandatory for certain banking organizations with significant exposure
to market risk beginning no later than January 1, 1998. See ''Market-Risk
Measure,'' below.
2. The risk-based capital measure is based on a framework developed jointly
by supervisory authorities from the G-10 countries. The Federal Reserve
implemented the risk-based measure in January 1989. This section provides
a brief overview of the current risk-based capital measure. More detailed
discussions can be found in the Federal Reserve's Commercial Bank Examination
Manual. Specific guidelines for calculating the risk-based capital ratio
are found in Regulation H (12 CFR 208, appendixes A and E) for state member
banks and in Regulation Y (12 CFR 225, appendixes A and E) for bank holding
companies.
3. The Basel Committee on Banking Supervision affirmed this view in a
release issued in October 1998, which stated that common shareholders'
funds are the key element of capital.
4. See the Commercial Bank Examination Manual for a complete discussion
of risk-weighted assets.
5. OECD countries are defined to include all full members of the Organization
for Economic Cooperation and Development regardless of entry date, as
well as countries that have concluded special lending arrangements with
the International Monetary Fund (IMF) associated with the IMF's General
Arrangements to Borrow, but excludes any country that has rescheduled
its external sovereign debt within the previous five years. As of May
1999, the OECD countries were Australia, Austria, Belgium, Canada, the
Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Japan, Korea, Luxembourg, Mexico, the Netherlands, New
Zealand, Norway, Poland, Portugal, Spain, Sweden, Switzerland, Turkey,
the United Kingdom, and the United States. Saudi Arabia has concluded
special lending arrangements with the IMF associated with the IMF's General
Arrangements to Borrow.
6. The tier 1 leverage measure, intended to be a supplement to the risk-based
capital measure, was adopted by the Federal Reserve in 1990. Guidelines
for calculating the tier 1 leverage ratio are found in Regulation H (12
CFR 208, appendix B) for state member banks and in Regulation Y (12 CFR
225, appendix D) for bank holding companies.
CREDIT-EQUIVALENT COMPUTATIONS FOR DERIVATIVE CONTRACTS
Applicable Derivative Contracts
Credit-equivalent amounts are computed for each of the following off-balance-sheet
contracts:
• interest-rate contracts
- single-currency interest-rate swaps
- basis swaps
- forward rate agreements
- interest-rate options purchased (including caps, collars, and floors
purchased) - any other instrument linked to interest rates that
gives rise to similar credit risks (including when-issued
securities and forward forward deposits accepted)
• exchange-rate contracts
- cross-currency interest-rate swaps
- forward foreign-exchange-rate contracts
- currency options purchased
- any other instrument linked to exchange rates that gives rise to similar
credit risks
• equity derivative contracts
- equity-linked swaps
- equity-linked options purchased
- forward equity-linked contracts
- any other instrument linked to equities that gives rise to similar credit
risks
• commodity (including precious metal) derivative contracts
- commodity-linked swaps
- commodity-linked options purchased
- forward commodity-linked contracts
- any other instrument linked to commodities that gives rise to similar
credit risks
• credit derivatives
- credit-default swaps
- total-rate-of-return swaps
- other types of credit derivatives
Exceptions
Exchange-rate contracts with an original maturity of 14 or fewer calendar
days and derivative contracts traded on exchanges that require daily receipt
and payment of cash variation margin may be excluded from the risk-based
ratio calculation. Gold contracts are accorded the same treatment as exchange-rate
contracts except that gold contracts with an original maturity of 14 or
fewer calendar days are included in the risk-based ratio calculation.
Over-the-counter options purchased are included and treated in the same
way as other derivative contracts.
Calculation of Credit-Equivalent Amounts
The credit-equivalent amount of a derivative contract (excluding credit
derivatives) that is not subject to a qualifying bilateral netting contract
is equal to the sum of-
• the current exposure (sometimes referred to as the replacement
cost) of the contract and
• an estimate of the potential future credit exposure of the contract.
The current exposure is determined by the mark-to-market value of the
contract. If the mark-to-market value is positive, then the current exposure
is equal to that mark-to-market value. If the mark-to-market value is
zero or negative, then the current exposure is zero. Mark-to-market values
are measured in dollars, regardless of the currency or currencies specified
in the contract, and should reflect changes in the relevant rates, as
well as in counterparty credit quality.
The potential future credit exposure of a contract, including a contract
with a negative mark-to-market value, is estimated by multiplying the
notional principal amount of the contract by a credit-conversion factor.
Banking organizations should use, subject to examiner review, the effective
rather than the apparent or stated notional amount in this calculation.
The conversion factors (in percent) are in table 1. The Board has noted
that these conversion factors, which are based on observed volatilities
of the particular types of instruments, are subject to review and modification
in light of changing volatilities or market conditions.
For a contract that is structured such that on specified dates any outstanding
exposure is settled and the terms are reset so that the market value of
the contract is zero, the remaining maturity is equal to the time until
the next reset date. For an interest-rate contract with a remaining maturity
of more than one year that meets these criteria, the minimum conversion
factor is 0.5 percent.
For a contract with multiple exchanges of principal, the conversion factor
is multiplied by the number of remaining payments in the contract. A derivative
contract not included in the definitions of interest-rate, exchange-rate,
equity, or commodity contracts is subject to the same conversion factors
as a commodity, excluding precious metals.
No potential future credit exposure is calculated for a single-currency
interest-rate swap in which payments are made based on two floating-rate
indexes, so-called floating/floating or basis swaps. The credit exposure
on these contracts is evaluated solely on the basis of their mark-to-market
values.
Examples of the calculation of credit-equivalent amounts for selected
instruments are in table 2.
Avoidance of Double Counting
In certain cases, credit exposures arising from derivative contracts may
be reflected, in part, on the balance sheet. To avoid double counting
these exposures in the assessment of capital adequacy and, perhaps, assigning
inappropriate risk weights, examiners may need to exclude counterparty
credit exposures arising from the derivative instruments covered by the
guidelines from balance-sheet assets when calculating a banking organization's
risk-based capital ratios. This exclusion will eliminate the possibility
that an organization could be required to hold capital against both an
off-balance-sheet and on-balance-sheet amount for the same item. This
treatment is not accorded to margin accounts and accrued receivables related
to interest-rate and exchange-rate contracts.
The aggregate on-balance-sheet amount excluded from the risk-based capital
calculation is equal to the lower of-
• each contract's positive on-balance-sheet amount or
• its positive market value included in the off-balance-sheet risk-based
capital calculation.
For example, a forward contract that is marked to market will have the
same market value on the balance sheet as is used in calculating the credit-equivalent
amount for off-balance-sheet exposures under the guidelines. Therefore,
the on-balance-sheet amount is not included in the risk-based capital
calculation. When either the contract's on-balance-sheet amount or its
market value is negative or zero, no deduction from on-balance-sheet items
is necessary for that contract.
If the positive on-balance-sheet asset amount exceeds the contract's market
value, the excess (up to the amount of the on-balance-sheet asset) should
be included in the appropriate risk-weight category. For example, a purchased
option will often have an on-balance-sheet amount equal to the fee paid
until the option expires. If that amount exceeds market value, the excess
of carrying value over market value would be included in the appropriate
risk-weight category for purposes of the on-balance-sheet portion of the
calculation.
Netting of Swaps and Similar Contracts
Netting refers to the offsetting of positive and negative mark-to-market
values in the determination of a current exposure to be used in the calculation
of a credit-equivalent amount. Any legally enforceable form of bilateral
netting (that is, netting with a single counterparty) of derivative contracts
is recognized for purposes of calculating the credit-equivalent amount
provided that-
• the netting is accomplished under a written netting contract
that creates a single legal obligation, covering all included individual
contracts, with the effect that the organization would have a claim to
receive, or an obligation to receive or pay, only the net amount of the
sum of the positive and negative mark-to-market values on included individual
contracts if a counterparty, or a counterparty to whom the contract has
been validly assigned, fails to perform due to default, insolvency, liquidation,
or similar circumstances;
• the banking organization obtains written and reasoned legal opinions
that in the event of a legal challenge-including one resulting from default,
insolvency, liquidation, or similar circumstances-the relevant court and
administrative authorities would find the banking organization's exposure
to be such a net amount under-
-the law of the jurisdiction in which the counterparty is chartered or
the equivalent location in the case of non-corporate entities, and if
a branch of the counterparty is involved, then also under the law of the
jurisdiction in which the branch is located; -the law that governs the
individual contracts covered by the netting contract; and -the law that
governs the netting contract;
• the banking organization establishes and maintains procedures
to ensure that the legal characteristics of netting contracts are kept
under review in light of possible changes in relevant law; and
• the banking organization maintains documentation in its files
that is adequate to support the netting of rate contracts, including a
copy of the bilateral netting contract and necessary legal opinions.
A contract containing a walkaway clause is not eligible for netting for
purposes of calculating the credit-equivalent amount.
By netting individual contracts for the purpose of calculating credit-equivalent
amounts of derivative contracts, a banking organization represents that
it has met the requirements of the risk-based measure of the capital adequacy
guidelines for bank holding companies and that all the appropriate documents
are in the organization's files and available for inspection by the Federal
Reserve. The Federal Reserve may determine that a banking organization's
files are inadequate or that a netting contract, or any of its underlying
individual contracts, may not be legally enforceable. If such a determination
is made, the netting contract may be disqualified from recognition for
risk-based capital purposes, or underlying individual contracts may be
treated as though they are not subject to the netting contract.
The credit-equivalent amount of contracts that are subject to a qualifying
bilateral netting contract is calculated by adding-
• the current exposure of the netting contract (net current exposure)
and
• the sum of the estimates of the potential future credit exposures
on all individual contracts subject to the netting contract (gross potential
future exposure) adjusted to reflect the effects of the netting contract.
The net current exposure of the netting contract is determined by summing
all positive and negative mark-to-market values of the individual contracts
included in the netting contract. If the net sum of the mark-to-market
values is positive, then the current exposure of the netting contract
is equal to that sum. If the net sum of the mark-to-market values is zero
or negative, then the current exposure of the netting contract is zero.
The Federal Reserve may determine that a netting contract qualifies for
risk-based capital netting treatment even though certain individual contracts
may not qualify. In these instances, the non-qualifying contracts should
be treated as individual contracts that are not subject to the netting
contract.
Gross potential future exposure or Agross is calculated by summing the
estimates of potential future exposure for each individual contract subject
to the qualifying bilateral netting contract. The effects of the bilateral
netting contract on the gross potential future exposure are recognized
through the application of a formula that results in an adjusted add-on
amount (Anet). The formula, which employs the ratio of net current exposure
to gross current exposure (NGR), is expressed as:
Anet = (0.4 × Agross) + 0.6(NGR × Agross)
The NGR may be calculated in accordance with either the counterparty-by-counterparty
approach or the aggregate approach. Under the counterparty-by-counterparty
approach, the NGR is the ratio of the net current exposure for a netting
contract to the gross current exposure of the netting contract. The gross
current exposure is the sum of the current exposures of all individual
contracts subject to the netting contract. Net negative mark-to-market
values for individual netting contracts with the same counterparty may
not be used to offset net positive mark-to-market values for other netting
contracts with the same counterparty.
Under the aggregate approach, the NGR is the ratio of the sum of all the
net current exposures for qualifying bilateral netting contracts to the
sum of all the gross current exposures for those netting contracts (each
gross current exposure is calculated in the same manner as in the counterparty-by-counterparty
approach). Net negative mark-to-market values for individual counterparties
may not be used to offset net positive current exposures for other counterparties.
A banking organization must consistently use either the counterparty-by-counterparty
approach or the aggregate approach to calculate the NGR. Regardless of
the approach used, the NGR should be applied individually to each qualifying
bilateral netting contract to determine the adjusted add-on for that netting
contract.
In the event a netting contract covers contracts that are normally excluded
from the risk-based ratio calculation-for example, exchange-rate contracts
with an original maturity of 14 or fewer calendar days or instruments
traded on exchanges that require daily payment of cash variation margin-an
institution may elect to either include or exclude all mark-to-market
values of such contracts when determining net current exposure, provided
the method chosen is applied consistently.
Examiners are to review the netting of off-balance-sheet derivative contractual
arrangements used by banking organizations when calculating or verifying
risk-based capital ratios to ensure that the positions of such contracts
are reported gross unless the net positions of those contracts reflect
netting arrangements that comply with the netting requirements listed
previously.
CAPITAL TREATMENT OF CREDIT DERIVATIVES
Credit derivatives are off-balance-sheet
arrangements that allow one party (the beneficiary) to transfer credit
risk of a reference asset-which the beneficiary may or may not own-to
another party (the guarantor). Many banks increasingly use these instruments
to manage their overall credit-risk exposure. In general, credit derivatives
have three distinguishing features:
1. the transfer of the credit risk associated with a reference asset through
contingent payments based on events of default and, usually, the prices
of instruments before, at, and shortly after default (reference assets
are most often traded sovereign and corporate debt instruments or syndicated
bank loans)
2. the periodic exchange of payments or the payment of a premium rather
than the payment of fees customary with other off-balance-sheet credit
products, such as letters of credit
3. the use of an International Swap Derivatives Association (ISDA) master
agreement and the legal format of a derivatives contract
For risk-based capital purposes, total-rate-of-return swaps and credit-default
swaps generally should be treated as off-balance-sheet direct credit substitutes.7
The notional amount of a contract should be converted at 100 percent to
determine the credit-equivalent amount to be included in the risk-weighted
assets of a guarantor. 8
A bank that provides a guarantee through a credit derivative transaction
should assign its credit exposure to the risk category appropriate to
the obligor of the reference asset or any collateral. On the other hand,
a bank that owns the underlying asset upon which effective credit protection
has been acquired through a credit derivative may, under certain circumstances,
assign the unamortized portion of the underlying asset to the risk category
appropriate to the guarantor (for example, the 20 percent risk category
if the guarantor is an OECD bank).9
Whether the credit derivative is considered an eligible guarantee for
purposes of risk-based capital depends on the degree of credit protection
actually provided, which may be limited depending on the terms of the
arrangement. For example, a relatively restrictive definition of a default
event or a materiality threshold that requires a comparably high percentage
of loss to occur before the guarantor is obliged to pay could effectively
limit the amount of credit risk actually transferred in the transaction.
If the terms of the credit derivative arrangement significantly limit
the degree of risk transference, then the beneficiary bank cannot reduce
the risk weight of the ''protected'' asset to that of the guarantor. On
the other hand, even if the transfer of credit risk is limited, a banking
organization providing limited credit protection through a credit derivative
should hold appropriate capital against the underlying exposure while
the organization is exposed to the credit risk of the reference asset.
Banking organizations providing a guarantee through a credit derivative
may mitigate the credit risk associated with the transaction by entering
into an offsetting credit derivative with another counterparty, a so-called
''back-to-back'' position. Organizations that have entered into such a
position may treat the first credit derivative as guaranteed by the offsetting
transaction for risk-based capital purposes. Accordingly, the notional
amount of the first credit derivative may be assigned to the risk category
appropriate to the counterparty providing credit protection through the
offsetting credit derivative arrangement (for example, to the 20 percent
risk category if the counterparty is an OECD bank).
In some instances, the reference asset in the credit derivative transaction
may not be identical to the underlying asset for which the beneficiary
has acquired credit protection. For example, a credit derivative used
to offset the credit exposure of a loan to a corporate customer may use
a publicly traded corporate bond of the customer as the reference asset,
whose credit quality serves as a proxy for the on-balance-sheet loan.
In such a case, the underlying asset will still generally be considered
guaranteed for capital purposes as long as both the underlying asset and
the reference asset are obligations of the same legal entity and have
the same level of seniority in bankruptcy. In addition, banking organizations
offsetting credit exposure in this manner would be obligated to demonstrate
to examiners that there is a high degree of correlation between the two
instruments; the reference instrument is a reasonable and sufficiently
liquid proxy for the underlying asset so that the instruments can be reasonably
expected to behave similarly in the event of default; and, at a minimum,
the reference asset and underlying asset are subject to mutual cross-default
provisions. A banking organization that uses a credit derivative which
is based on a reference asset that differs from the protected underlying
asset must document the credit derivative being used to offset credit
risk and must link it directly to the asset or assets whose credit risk
the transaction is designed to offset. The documentation and the effectiveness
of the credit derivative transaction are subject to examiner review. Banking
organizations providing credit protection through such arrangements must
hold capital against the risk exposures that are assumed.
Some credit derivative transactions provide credit protection for a group
or basket of reference assets and call for the guarantor to absorb losses
on only the first asset in the group that defaults. Once the first asset
in the group defaults, the credit protection for the remaining assets
covered by the credit derivative ceases. If examiners determine that the
credit risk for the basket of assets has effectively been transferred
to the guarantor and the beneficiary banking organization owns all of
the reference assets included in the basket, then the beneficiary may
assign the asset with the smallest dollar amount in the group-if less
than or equal to the notional amount of the credit derivative-to the risk
category appropriate to the guarantor. Conversely, a banking organization
extending credit protection through a credit derivative on a basket of
assets must assign the contract's notional amount of credit exposure to
the highest risk category appropriate to the assets in the basket. In
addition to holding capital against credit risk, a bank that is subject
to the market-risk rule (see below) must hold capital against market risk
for credit derivatives held in its trading account. (For a description
of market-risk capital requirements, see SR-97-18).
7. Unlike total-rate-of-return swaps
and credit-default swaps, credit-linked notes are on-balance-sheet assets
or liabilities. A guarantor bank should assign the on-balance-sheet amount
of the credit-linked note to the risk category appropriate to either the
issuer or the reference asset, whichever is higher. For a beneficiary
bank, cash consideration received in the sale of the note may be considered
as collateral for risk-based capital purposes.
8. A guarantor bank that has made cash payments representing depreciation
on reference assets may deduct such payments from the notional amount
when computing credit-equivalent amounts for capital purposes.
9. In addition to holding capital against credit risk, a bank that is
subject to the market-risk rule (see ''Market-Risk Measure,'' below) must
hold capital against market risk for credit derivatives held in its trading
account.
CAPITAL TREATMENT OF SYNTHETIC COLLATERALIZED
LOAN OBLIGATIONS
Credit derivatives can be used to synthetically
replicate collateralized loan obligations (CLOs). Banking organizations
can use CLOs and their synthetic variants to manage their balance sheets
and, in some instances, transfer credit risk to the capital markets. These
transactions allow economic capital to be allocated more efficiently,
resulting in, among other things, improved shareholders' returns. A CLO
is an asset-backed security that is usually supported by a variety of
assets, including whole commercial loans, revolving credit facilities,
letters of credit, banker's acceptances, or other asset-backed securities.
In a typical CLO transaction, the sponsoring banking organization transfers
the loans and other assets to a bankruptcy-remote special-purpose vehicle
(SPV), which then issues asset-backed securities consisting of one or
more classes of debt. The CLO enables the sponsoring institution to reduce
its leverage and risk-based capital requirements, improve its liquidity,
and manage credit concentrations.
The first synthetic CLO issued in 1997 used credit-linked notes (CLNs).10
Rather than transferring assets to the SPV, the sponsoring bank issued
CLNs to the SPV, individually referencing the payment obligation of a
particular company or ''reference obligor.'' In that particular transaction,
the notional amount of the CLNs issued equaled the dollar amount of the
reference assets the sponsor was hedging on its balance sheet. Since that
time, other structures have evolved that also use credit-default swaps
to transfer credit risk and create different levels of risk exposure,
but that hedge only a portion of the notional amount of the overall reference
portfolio. In most traditional CLO structures, assets are actually transferred
into the SPV. In synthetic securitizations, the underlying exposures that
make up the reference portfolio remain in the institution's banking book.
The credit risk is transferred into the SPV through credit-default swaps
or CLNs. In this way, the institution is able to avoid sensitive client-relationship
issues arising from loan-transfer notification requirements, loan-assignment
provisions, and loan-participation restrictions. Client confidentiality
also can be maintained.
Under the risk-based capital guidelines, corporate credits are typically
assigned to the 100 percent risk category and are assessed 8 percent capital.
In the case of high-quality investment-grade corporate exposures, the
8 percent capital requirement may exceed the economic capital that a bank
sets aside to cover the credit risk of the transaction. Clearly, one of
the motivations behind CLOs and other securitizations is to more closely
align the sponsoring institution's regulatory capital requirements with
the economic capital required by the market. The introduction of synthetic
CLOs has raised questions about their treatment for purposes of calculating
the leverage and risk-based capital ratios of the Federal Reserve and
other banking agencies.11
In this regard, supervisors and examiners should consider the capital
treatment of synthetic CLOs from the perspective of both investors and
sponsoring banking organizations for three types of transactions: (1)
the sponsoring banking organization, through a synthetic CLO, hedges the
entire notional amount of a reference asset portfolio; (2) the sponsoring
banking organization hedges a portion of the reference portfolio and retains
a high-quality, senior risk position that absorbs only those credit losses
in excess of the junior-loss positions; and (3) the sponsoring banking
organization retains a subordinated position that absorbs first losses
in a reference portfolio. Each of these transactions is explained more
fully below.
Entire Notional Amount of the Reference Portfolio Hedged
In a synthetic securitization that hedges the entire notional amount of
the reference portfolio, an SPV acquires the credit risk on a reference
portfolio by purchasing CLNs issued by the sponsoring banking organization.
The SPV funds the purchase of the CLNs by issuing a series of notes in
several tranches to third-party investors. The investor notes are in effect
collateralized by the CLNs. Each CLN represents one obligor and the bank's
credit-risk exposure to that obligor, which may take the form of, for
example, bonds, commitments, loans, and counterparty exposures. Since
the note-holders are exposed to the full amount of credit risk associated
with the individual reference obligors, all of the credit risk of the
reference portfolio is shifted from the sponsoring bank to the capital
markets. The dollar amount of notes issued to investors equals the notional
amount of the reference portfolio. If there is a default of any obligor
linked to a CLN in the SPV, the institution will call the individual note
and redeem it based on the repayment terms specified in the note agreement.
The term of each CLN is set such that the credit exposure to which it
is linked matures before the maturity of the CLN. This ensures that the
CLN will be in place for the full term of the exposure to which it is
linked.
An investor in the notes issued by the SPV is exposed to the risk of default
of the underlying reference assets, as well as to the risk that the sponsoring
institution will not repay principal at the maturity of the notes. Because
of the linkage between the credit quality of the sponsoring institution
and the issued notes, a downgrade of the sponsor's credit rating most
likely will result in the notes also being downgraded. Thus, a banking
organization investing in this type of synthetic CLO should assign the
notes to the higher of the risk categories appropriate to the underlying
reference assets or the issuing entity.
For purposes of risk-based capital, the sponsoring banking organizations
may treat the cash proceeds from the sale of CLNs that provide protection
against underlying reference assets as cash collateralizing these assets.12
This treatment would permit the reference assets, if carried on the sponsoring
institution's books, to be assigned to the zero percent risk category
to the extent that their notional amount is fully collateralized by cash.
This treatment may be applied even if the cash collateral is transferred
directly into the general operating funds of the institution and is not
deposited in a segregated account. The synthetic CLO would not confer
any bene-fits to the sponsoring banking organization for purposes of calculating
its tier 1 leverage ratio because the reference assets remain on the organization's
balance sheet.
10. CLNs are obligations whose principal repayment is conditioned upon
the performance of a referenced asset or portfolio. The assets' performance
may be based on a variety of measures, such as movements in price or credit
spread, or the occurrence of default.
11. For more information, see SR-99-32, ''Capital Treatment for Synthetic
Collateralized Obligations.''
12. The CLNs should not contain terms that would significantly limit the
credit protection provided against the underlying reference assets, for
example, a materiality threshold that requires a relatively high percentage
of loss to occur before CLN payments are adversely affected, or a strucEagle
Tradersg of CLN post-default payments that does not adequately pass through
credit-related losses on the reference assets to investors in the CLNs.
High-Quality, Senior Risk Position in the Reference Portfolio Retained
In some synthetic CLOs, the sponsoring banking organization uses a combination
of credit-default swaps and CLNs to essentially transfer the credit risk
of a designated portfolio of its credit exposures to the capital markets.
This type of transaction allows the sponsoring institution to allocate
economic capital more efficiently and to significantly reduce its regulatory
capital requirements. In this structure, the sponsoring banking organization
purchases default protection from an SPV for a specifically identified
portfolio of banking-book credit exposures, which may include letters
of credit and loan commitments. The credit risk on the identified reference
portfolio (which continues to remain in the sponsor's banking book) is
transferred to the SPV through the use of credit-default swaps. In exchange
for the credit protection, the sponsoring institution pays the SPV an
annual fee. The default swaps on each of the obligors in the reference
portfolio are structured to pay the average default losses on all senior
unsecured obligations of defaulted borrowers. To support its guarantee,
the SPV sells CLNs to investors and uses the cash proceeds to purchase
Treasury notes from the U.S. government. The SPV then pledges the Treasuries
to the sponsoring banking organization to cover any default losses.13
The CLNs are often issued in multiple tranches of differing seniority
and in an aggregate amount that is significantly less than the notional
amount of the reference portfolio. The amount of notes issued typically
is set at a level sufficient to cover some multiple of expected losses,
but well below the notional amount of the reference portfolio being hedged.
There may be several levels of loss in this type of synthetic securitization.
The first-loss position may be a small cash reserve, sufficient to cover
expected losses, that accumulates over a period of years and is funded
from the excess of the SPV's income (that is, the yield on the Treasury
securities plus the credit-default-swap fee) over the interest paid to
investors on the notes. The investors in the SPV assume a second-loss
position through their investment in the SPV's senior and junior notes,
which tend to be rated AAA and BB, respectively. Finally, the sponsoring
banking organization retains a high-quality, senior risk position that
would absorb any credit losses in the reference portfolio that exceed
the first- and second-loss positions. Typically, no default payments are
made until the maturity of the overall transaction, regardless of when
a reference obligor defaults. While operationally important to the sponsoring
banking organization, this feature has the effect of ignoring the time
value of money. Thus, when the reference obligor defaults under the terms
of the credit derivative and the reference asset falls significantly in
value, the sponsoring banking organization should, in accordance with
generally accepted accounting principles, make appropriate adjustments
in its regulatory reports to reflect the estimated loss relating to the
time value of money.
For risk-based capital purposes, banking organizations investing in the
notes must assign them to the risk weight appropriate to the underlying
reference assets.14
A banking organization sponsoring such a transaction must include in its
risk-weighted assets its retained senior exposures in the reference portfolio,
to the extent these are held in its banking book. The portion of the reference
portfolio that is collateralized by the pledged Treasury securities may
be assigned a zero percent risk weight. The remainder of the portfolio
should be risk weighted according to the obligor of the exposures, unless
certain stringent minimum conditions are met. When the sponsoring institution
has virtually eliminated its credit-risk exposure to the reference portfolio
through the issuance of CLNs, and when the other stringent minimum requirements
are met, the institution may assign the uncollateralized portion of its
retained senior position in the reference portfolio to the 20 percent
risk weight. To the extent that the reference portfolio includes loans
and other balance-sheet assets in the banking book, a banking organization
that sponsors this type of synthetic securitization would not realize
any benefits with respect to the determination of its leverage ratio.
The stringent minimum requirements, which are discussed more fully in
the annex to SR-99-32, include (1) the probability of loss on the retained
senior position is extremely low due to the high credit quality of the
reference portfolio and the amount of prior credit protection; 2) market
discipline is injected into the process through the sale of CLNs into
the market, the most senior of which must be rated AAA by a nationally
recognized credit rating agency; and 3) the sponsoring institution performs
rigorous and robust stress testing and demonstrates that the level of
credit enhancement is sufficient to protect itself from losses under scenarios
appropriate to the specific transaction. The Federal Reserve may impose
other requirements as deemed necessary to ensure that the sponsoring institution
has virtually eliminated all of its credit exposure. Furthermore, supervisors
and examiners retain the discretion to increase the risk-based capital
requirement assessed against the retained senior exposure in these structures,
if the underlying asset pool deteriorates significantly.
Based on a qualitative review, Federal Reserve staff will determine on
a case-by-case basis whether the senior retained portion of a sponsoring
banking organization's synthetic securitization qualifies for the 20 percent
risk weight. The sponsoring institution must be able to demonstrate that
virtually all of the credit risk of the reference portfolio has been transferred
from the banking book to the capital markets. As is the case with organizations
engaging in more traditional securitization activities, examiners must
carefully evaluate whether the institution is fully capable of assessing
the credit risk it retains in its banking book and whether it is adequately
capitalized given its residual risk exposure. Supervisors will require
the sponsoring organization to maintain higher levels of capital if it
is not deemed to be adequately capitalized given the retained residual
risks. In addition, an institution sponsoring synthetic securitizations
must adequately disclose to the marketplace the effect of the transaction
on its risk profile and capital adequacy. A failure on the part of the
sponsoring banking organization to require the investors in the CLNs to
absorb the credit losses that they contractually agreed to assume may
be considered an unsafe and unsound banking practice. In addition, this
failure generally would constitute ''implicit recourse'' or support to
the transaction that would result in the sponsoring banking organization
losing the preferential capital treatment on its retained senior position.
If an organization sponsoring a synthetic securitization does not meet
the stringent minimum criteria outlined in SR-99-32, it still may reduce
the risk-based capital requirement on the senior risk position retained
in the banking book by transferring the remaining credit risk to a third-party
OECD bank through the use of a credit derivative. Provided the credit
derivative transaction qualifies as a guarantee under the risk-based capital
guidelines, the risk weight on the senior position may be reduced from
100 percent to 20 percent. Institutions may not enter into non-substantive
transactions that transfer banking-book items into the trading account
to obtain lower regulatory capital requirements.15
13. The names of corporate obligors
included in the reference portfolio may be disclosed to investors in the
CLNs.
14. Under this type of transaction, if a structure exposes investing banking
organizations to the creditworthiness of a substantive issuer (for example,
the sponsoring institution), then the investing institutions should assign
the notes to the higher of the risk categories appropriate to the underlying
reference assets or the sponsoring institution.
15. For instance, a lower risk weight would not be applied to a non-substantive
transaction in which the sponsoring institution enters into a credit derivative
to pass the credit risk of the senior retained portion held in its banking
book to an OECD bank, and then enters into a second credit derivative
transaction with the same OECD bank in which it reassumes into its trading
account the credit risk initially transferred.
16. Because the credit risk of the senior position is not transferred
to the capital markets but, instead, remains with the intermediary bank,
the sponsoring banking organization should ensure that its counterparty
is of high credit quality, for example, at least investment grade.
Retention of a First-Loss Position
In certain synthetic transactions, the sponsoring banking organization
may retain the credit risk associated with a first-loss position and,
through the use of credit-default swaps, pass the second and senior-loss
positions to a third-party entity, most often an OECD bank. The third-party
entity, acting as an intermediary, enters into offsetting credit-default
swaps with an SPV, thus transferring its credit risk associated with the
second-loss position to the SPV.16
As described in the second transaction type described above, the SPV then
issues CLNs to the capital markets for a portion of the reference portfolio
and purchases Treasury collateral to cover some multiple of expected losses
on the underlying exposures.
Two alternative approaches could be used to determine how the sponsoring
banking organization should treat the overall transaction for risk-based
capital purposes. The first approach employs an analogy to the low-level
capital rule for assets sold with recourse. Under this rule, a transfer
of assets with recourse that is contractually limited to an amount less
than the effective risk-based capital requirements for the transferred
assets is assessed a total capital charge equal to the maximum amount
of loss possible under the recourse obligation. If this rule was applied
to a sponsoring banking organization retaining a one percent first-loss
position on a synthetically securitized portfolio that would otherwise
be assessed 8 percent capital, the organization would be required to hold
dollar-for-dollar capital against the one percent first loss risk position.
The sponsoring institution would not be assessed a capital charge against
the second and senior risk positions.17
The second approach employs a literal reading of the capital guidelines
to determine the sponsoring banking organization's risk-based capital
charge. In this instance, the one percent first-loss position retained
by the sponsoring institution would be treated as a guarantee, that is,
a direct credit substitute, which would be assessed an 8 percent capital
charge against its face value of one percent. The second-loss position,
which is collateralized by Treasury securities, would be viewed as fully
collateralized and subject to a zero percent capital charge. The senior-loss
position guaranteed by the intermediary bank would be assigned to the
20 percent risk category appropriate to claims guaranteed by OECD banks.18
It is possible that this approach may result in a higher risk-based capital
requirement than the dollar-for-dollar capital charge imposed by the first
approach- depending on whether the reference portfolio consists primarily
of loans to private obligors, or undrawn long-term commitments. These
commitments generally have an effective risk-based capital requirement
that is one-half the requirement for loans, since they are converted to
an on-balance-sheet credit-equivalent amount using the 50 percent conversion
factor. If the reference pool consists primarily of drawn loans to commercial
obligors, then the capital requirement on the senior-loss position would
be significantly higher than if the reference portfolio contained only
undrawn long-term commitments. As a result, the capital charge for the
overall transaction could be greater than the dollar-for-dollar capital
requirement set forth in the first approach.
Sponsoring institutions are required to hold capital against a retained
first-loss position in a synthetic securitization. The capital should
equal the higher of the two capital charges resulting from the sponsoring
institution's application of the first and second approaches outlined
above. Further, although the sponsoring banking organization retains only
the credit-risk associated with the first-loss position, it still should
continue to monitor all the underlying credit exposures of the reference
portfolio to detect any changes in the credit-risk profile of the counterparties.
This is important to ensure that the institution has adequate capital
to protect against unexpected losses. Examiners should determine whether
the sponsoring bank has the capability to assess and manage the retained
risk in its credit portfolio after the synthetic securitization is completed.
For risk-based capital purposes, banking organizations investing in the
notes must assign them to the risk weight appropriate to the underlying
reference assets.19
17. A banking organization that sponsors
this type of synthetic securitization would not realize any benefits in
the determination of its leverage ratio since the reference assets themselves
remain on the sponsoring institution's balance sheet.
18. If the intermediary is a banking organization, then it could place
both sets of credit-default swaps in its trading account and, if subject
to the Federal Reserve's market-risk capital rules, use its general market-risk
model and, if approved, specific-risk model to calculate the appropriate
risk-based capital requirement. If the specific-risk model has not been
approved, then the sponsoring banking organization would be subject to
the standardized specific-risk capital charge.
19. Under this type of transaction, if a structure exposes investing banking
organizations to the creditworthiness of a substantive issuer (for example,
the sponsoring institution), then the investing institutions should assign
the notes to the higher of the risk categories appropriate to the underlying
reference assets or the sponsoring institution.
