Basel ii Accord Sections 538 to 559

IV. Credit Risk — Securitisation Framework
A. Scope and definitions of transactions covered under the securitisation
framework
 
538. Banks must apply the securitisation framework for determining regulatory capital
requirements on exposures arising from traditional and synthetic securitisations or similar
structures that contain features common to both. Since securitisations may be structured in
many different ways, the capital treatment of a securitisation exposure must be determined
on the basis of its economic substance rather than its legal form.
 
Similarly, supervisors will look to the economic substance of a transaction to determine whether it should be subject to the securitisation framework for purposes of determining regulatory capital. Banks are encouraged to consult with their national supervisors when there is uncertainty about whether a given transaction should be considered a securitisation. For example, transactions involving cash flows from real estate (e.g. rents) may be considered specialised lending exposures, if warranted.
 
539. A traditional securitisation is a structure where the cash flow from an underlying pool
of exposures is used to service at least two different stratified risk positions or tranches
reflecting different degrees of credit risk. Payments to the investors depend upon the
performance of the specified underlying exposures, as opposed to being derived from an
obligation of the entity originating those exposures.
 
The stratified/tranched structures that characterise securitisations differ from ordinary senior/subordinated debt instruments in that junior securitisation tranches can absorb losses without interrupting contractual payments to more senior tranches, whereas subordination in a senior/subordinated debt structure is a matter of priority of rights to the proceeds of liquidation.
 
540. A synthetic securitisation is a structure with at least two different stratified risk
positions or tranches that reflect different degrees of credit risk where credit risk of an
underlying pool of exposures is transferred, in whole or in part, through the use of funded
(e.g. credit-linked notes) or unfunded (e.g. credit default swaps) credit derivatives or
guarantees that serve to hedge the credit risk of the portfolio. Accordingly, the investors’
potential risk is dependent upon the performance of the underlying pool.
 
541. Banks’ exposures to a securitisation are hereafter referred to as “securitisation
exposures”. Securitisation exposures can include but are not restricted to the following:
asset-backed securities, mortgage-backed securities, credit enhancements, liquidity facilities, interest rate or currency swaps, credit derivatives and tranched cover as described in paragraph 199. Reserve accounts, such as cash collateral accounts, recorded as an asset
by the originating bank must also be treated as securitisation exposures.
 
542. Underlying instruments in the pool being securitised may include but are not
restricted to the following: loans, commitments, asset-backed and mortgage-backed
securities, corporate bonds, equity securities, and private equity investments. The underlying pool may include one or more exposures.
 
B. Definitions and general terminology
 
1. Originating bank
 
543. For risk-based capital purposes, a bank is considered to be an originator with regard
to a certain securitisation if it meets either of the following conditions:
 
(a) The bank originates directly or indirectly underlying exposures included in the
securitisation;
or The bank serves as a sponsor of an asset-backed commercial paper (ABCP)
conduit or similar programme that acquires exposures from third-party entities. In
the context of such programmes, a bank would generally be considered a sponsor
and, in turn, an originator if it, in fact or in substance, manages or advises the
programme, places securities into the market, or provides liquidity and/or credit
enhancements.
 
2. Asset-backed commercial paper (ABCP) programme
 
544. An asset-backed commercial paper (ABCP) programme predominately issues
commercial paper with an original maturity of one year or less that is backed by assets or
other exposures held in a bankruptcy-remote, special purpose entity.
 
3. Clean-up call
 
545. A clean-up call is an option that permits the securitisation exposures (e.g. assetbacked
securities) to be called before all of the underlying exposures or securitisation
exposures have been repaid. In the case of traditional securitisations, this is generally
accomplished by repurchasing the remaining securitisation exposures once the pool balance
or outstanding securities have fallen below some specified level. In the case of a synthetic
transaction, the clean-up call may take the form of a clause that extinguishes the credit
protection.
 
4. Credit enhancement
 
546. A credit enhancement is a contractual arrangement in which the bank retains or
assumes a securitisation exposure and, in substance, provides some degree of added
protection to other parties to the transaction.
 
5. Credit-enhancing interest-only strip
 
547. A credit-enhancing interest-only strip (I/O) is an on-balance sheet asset that (i)
represents a valuation of cash flows related to future margin income, and (ii) is subordinated.
 
6. Early amortisation
 
548. Early amortisation provisions are mechanisms that, once triggered, allow investors
to be paid out prior to the originally stated maturity of the securities issued. For risk-based
capital purposes, an early amortisation provision will be considered either controlled or noncontrolled.
 
A controlled early amortisation provision must meet all of the following conditions.
 
(a) The bank must have an appropriate capital/liquidity plan in place to ensure that it
has sufficient capital and liquidity available in the event of an early amortisation.
 
(b) Throughout the duration of the transaction, including the amortisation period, there
is the same pro rata sharing of interest, principal, expenses, losses and recoveries
based on the bank’s and investors’ relative shares of the receivables outstanding at
the beginning of each month.
 
(c) The bank must set a period for amortisation that would be sufficient for at least 90%
of the total debt outstanding at the beginning of the early amortisation period to have
been repaid or recognised as in default; and
 
The pace of repayment should not be any more rapid than would be allowed by
straight-line amortisation over the period set out in criterion (c).
 
549. An early amortisation provision that does not satisfy the conditions for a controlled
early amortisation provision will be treated as a non-controlled early amortisation provision.
 
7. Excess spread
 
550. Excess spread is generally defined as gross finance charge collections and other
income received by the trust or special purpose entity (SPE, specified in paragraph 552)
minus certificate interest, servicing fees, charge-offs, and other senior trust or SPE
expenses.
 
8. Implicit support
 
551. Implicit support arises when a bank provides support to a securitisation in excess of
its predetermined contractual obligation.
 
9. Special purpose entity (SPE)
 
552. An SPE is a corporation, trust, or other entity organised for a specific purpose, the
activities of which are limited to those appropriate to accomplish the purpose of the SPE, and
the structure of which is intended to isolate the SPE from the credit risk of an originator or
seller of exposures. SPEs are commonly used as financing vehicles in which exposures are
sold to a trust or similar entity in exchange for cash or other assets funded by debt issued by
the trust.
 
C. Operational requirements for the recognition of risk transference
 
553. The following operational requirements are applicable to both the standardised and
IRB approaches of the securitisation framework.
 
1. Operational requirements for traditional securitisations
 
554. An originating bank may exclude securitised exposures from the calculation of riskweighted assets only if all of the following conditions have been met. Banks meeting these conditions must still hold regulatory capital against any securitisation exposures they retain.
 
(a) Significant credit risk associated with the securitised exposures has been
transferred to third parties.
 
(b) The transferor does not maintain effective or indirect control over the transferred
exposures. The assets are legally isolated from the transferor in such a way (e.g.
through the sale of assets or through subparticipation) that the exposures are put
beyond the reach of the transferor and its creditors, even in bankruptcy or
receivership. These conditions must be supported by an opinion provided by a
qualified legal counsel.
 
The transferor is deemed to have maintained effective control over the transferred
credit risk exposures if it:
(i) is able to repurchase from the transferee the previously transferred exposures in order to realise their benefits; or
(ii) is obligated to retain the risk of the transferred exposures. The transferor’s retention of servicing rights to the exposures will not necessarily constitute indirect control of the exposures.
 
(c)The securities issued are not obligations of the transferor. Thus, investors who
purchase the securities only have claim to the underlying pool of exposures.
 
(d) The transferee is an SPE and the holders of the beneficial interests in that entity
have the right to pledge or exchange them without restriction.
 
(e) Clean-up calls must satisfy the conditions set out in paragraph 557.
 
(f) The securitisation does not contain clauses that (i) require the originating bank to
alter systematically the underlying exposures such that the pool’s weighted average
credit quality is improved unless this is achieved by selling assets to independent
and unaffiliated third parties at market prices; (ii) allow for increases in a retained
first loss position or credit enhancement provided by the originating bank after the
transaction’s inception; or (iii) increase the yield payable to parties other than the
originating bank, such as investors and third-party providers of credit enhancements, in response to a deterioration in the credit quality of the underlying pool.
 
2. Operational requirements for synthetic securitisations
 
555. For synthetic securitisations, the use of CRM techniques (i.e. collateral, guarantees
and credit derivatives) for hedging the underlying exposure may be recognised for risk-based capital purposes only if the conditions outlined below are satisfied:
 
(a) Credit risk mitigants must comply with the requirements as set out in Section II.D of
this Framework.
 
(b) Eligible collateral is limited to that specified in paragraphs 145 and 146. Eligible
collateral pledged by SPEs may be recognised.
 
(c) Eligible guarantors are defined in paragraph 195. Banks may not recognise SPEs as
eligible guarantors in the securitisation framework.
 
(d) Banks must transfer significant credit risk associated with the underlying exposure to
third parties.
 
(e) The instruments used to transfer credit risk may not contain terms or conditions that
limit the amount of credit risk transferred, such as those provided below:
 
Clauses that materially limit the credit protection or credit risk transference (e.g.
significant materiality thresholds below which credit protection is deemed not to be
triggered even if a credit event occurs or those that allow for the termination of the
protection due to deterioration in the credit quality of the underlying exposures);
 
Clauses that require the originating bank to alter the underlying exposures to
improve the pool’s weighted average credit quality;
 
Clauses that increase the banks’ cost of credit protection in response to
deterioration in the pool’s quality;
 
Clauses that increase the yield payable to parties other than the originating bank,
such as investors and third-party providers of credit enhancements, in response to a
deterioration in the credit quality of the reference pool; and
 
Clauses that provide for increases in a retained first loss position or credit
enhancement provided by the originating bank after the transaction’s inception.
An opinion must be obtained from a qualified legal counsel that confirms the
enforceability of the contracts in all relevant jurisdictions.
 
(g) Clean-up calls must satisfy the conditions set out in paragraph 557.
 
556. For synthetic securitisations, the effect of applying CRM techniques for hedging the
underlying exposure are treated according to paragraphs 109 to 210. In case there is a
maturity mismatch, the capital requirement will be determined in accordance with paragraphs 202 to 205.
 
When the exposures in the underlying pool have different maturities, the longest
maturity must be taken as the maturity of the pool. Maturity mismatches may arise in the
context of synthetic securitisations when, for example, a bank uses credit derivatives to
transfer part or all of the credit risk of a specific pool of assets to third parties. When the
credit derivatives unwind, the transaction will terminate.
 
This implies that the effective maturity of the tranches of the synthetic securitisation may differ from that of the underlying exposures. Originating banks of synthetic securitisations must treat such maturity mismatches in the following manner. A bank using the standardised approach for securitisation must deduct all retained positions that are unrated or rated below investment grade.
 
A bank using the IRB approach must deduct unrated, retained positions if the
treatment of the position is deduction specified in paragraphs 609 to 643. Accordingly, when
deduction is required, maturity mismatches are not taken into account. For all other
securitisation exposures, the bank must apply the maturity mismatch treatment set forth in
paragraphs 202 to 205.
 
3. Operational requirements and treatment of clean-up calls
 
557. For securitisation transactions that include a clean-up call, no capital will be required
due to the presence of a clean-up call if the following conditions are met:
(i) the exercise of the clean-up call must not be mandatory, in form or in substance, but rather must be at the discretion of the originating bank;
(ii) the clean-up call must not be structured to avoid allocating losses to credit enhancements or positions held by investors or otherwise structured to provide credit enhancement; and
(iii) the clean-up call must only be exercisable when 10% or less of the original underlying portfolio, or securities issued remain, or, for synthetic securitisations, when 10% or less of the original reference portfolio value remains.
 
558. Securitisation transactions that include a clean-up call that does not meet all of the
criteria stated in paragraph 557 result in a capital requirement for the originating bank. For a
traditional securitisation, the underlying exposures must be treated as if they were not
securitised. Additionally, banks must not recognise in regulatory capital any gain-on-sale, as
defined in paragraph 562.
For synthetic securitisations, the bank purchasing protection must hold capital against the entire amount of the securitised exposures as if they did not benefit from any credit protection. If a synthetic securitisation incorporates a call (other than a cleanup
call) that effectively terminates the transaction and the purchased credit protection on a
specific date, the bank must treat the transaction in accordance with paragraph 556 and
paragraphs 202 to 205.
 
559. If a clean-up call, when exercised, is found to serve as a credit enhancement, the
exercise of the clean-up call must be considered a form of implicit support provided by the
bank and must be treated in accordance with the supervisory guidance pertaining to
securitisation transactions.
