    Moodys Approach to Rating Consumer LoanABS TransactionsConsumer Loan / Global

    Background

    This report details our approach to rating securitisation transactions that are backed by

    unsecured consumer loan receivables (defined as personal or purpose loans) and builds

    on our previously published reports, such as The Lognormal Method Applied to ABS

    Analysis, in June 2000.

    This methodology does not apply to revolving credit products (e.g., credit cards), secured

    auto loans/leases or other particular consumer products, which require a different analytical

    approach given the specifics of these assets.1

    We have rated consumer loan asset-backed securities (ABS) since the 1990s, when the

    securitisation of consumer loans in Europe, the Middle East and Africa (EMEA), Asia/Pacific

    and Latin America began in earnest. This type of securitisation provides funding and

    regulatory capital relief to the specialised lenders and banks that originate unsecuredconsumer loans.

    This report discusses the main risks of a typical transaction and describes the ratings process

    in five incremental steps:

    In the first section, we introduce a typical consumer loan securitisation structure anddiscuss the effect that specific key structural features may have on the credit

    enhancement levels of a hypothetical transaction.

    In the second section, we summarise the main product types and loan characteristics ofthe securitised portfolios.

    In the third section, we focus on the quantitative analysis performed in determiningratings for a consumer loan ABS transaction. This includes defining the asset-side modelinputs and describing our cash flow modelling processes.

    In the fourth section, we examine the legal risks found in consumer loan ABS. Finally, in section five, we identify the principal sources of uncertainty and ratings

    volatility relevant to this methodology.

    This report has been republished on October 12, 2012. The reference to the triangular distribution of losses in Latin

    American transactions has been deleted because we will use a lognormal distribution of losses for these transactions going

    forward. In addition, reference to Brazilian transactions being excluded from this methodology has been deleted.

    2 OCTOBER 12, 2012 RATING METHODOLOGY: MOODYS APPROACH TO RATING CONSUMER LOAN ABS TRANSACTIONS

    STRUCTURED FINANCE

    Executive SummaryA typical consumer loan portfolio is made up of personal

    loans and purpose loans. The former are usually granted to

    individuals to bridge a temporary liquidity need, finance

    one-off expenses or simply to refinance existing unsecured

    indebtedness (although the bank may or may not require aspecific purpose to be disclosed). The latter are usually

    originated at point of sale to finance the purchase of a

    specific item (e.g., durable goods, furniture or auto

    vehicles). Granularity and a short weighted-average life are

    also characteristic of such portfolios. Securitised loans are

    usually unsecured.

    The first step in rating a transaction backed by a portfolio

    of unsecured consumer loans is to parameterise the expected

    default distribution based on the historical performance

    data. We generally assume that defaults of a granular asset

    portfolio are lognormally distributed.

    Portfolio default distribution

    The lognormal default distribution for the relevant

    portfolio is defined by two key inputs: the mean and the

    standard deviation. From these two parameters, we derive

    the coefficient of variation (CoV), a measure of the

    portfolios volatility relative to the mean.

    Cumulative mean default assumption

    For each securitised pool, we typically receive historical

    performance data in the form of static cumulative default

    ratios by vintage of origination. As recently originated

    vintages have limited data points, we extrapolate the default

    rates of these vintages to derive the expected lifetime mean

    cumulative default rate. The average cumulative default

    probability (DP) across the cohorts provides a starting

    point mean DP of the portfolio. This value is then

    adjusted to take into account different factors including:

    observed performance trends in recent vintages,

    underwriting and servicing quality of the originator, and

    macroeconomic factors.

    A timing of default curve is associated with the meancumulative DP for the portfolio. This curve describes the

    proportion of defaults that occur in each modelled period.

    Standard deviation and CoV

    Historically observed cumulative default curves are used in

    deriving the standard deviation and hence the CoV of the

    lognormal distribution. A higher CoV implies a fatter tail

    of the distribution (i.e., a higher likelihood of high default

    scenarios materialising).

    In order to better understand whether the parameterisation

    of the lognormal distribution is appropriate and/orconsistent with other rated unsecured loan transactions, we

    will benchmark the deal mean and CoV assumptions

    against values assumed in other unsecured loan ABS and

    secured RMBS transactions and calculate the portfolio

    implied asset correlation and benchmark this against other

    similar transactions as well as the Basel II standard.

    Recovery rate

    We give limited benefit to recoveries in modelling, due to

    the unsecured nature of the loans backing the ABS notes.

    Assumed recovery rates are usually in the 0%-30% range,

    generally lower than the mean recovery rates assumed for

    secured loans or leases (such as RMBS or auto ABS

    transactions).

    Other asset-based inputs to the model

    Other key asset-based model inputs include the portfolio

    prepayment rate, its weighted average yield and

    amortisation profile.

    The cash flow model

    We aim to replicate the transaction structure in a cash flow

    model, such as ABS ROM. A simplified version of the

    model is available onwww.moodys.com.

    In addition to the asset-side modelling assumptions as

    described above, other important transaction-specific inputs

    include the hedging mechanism and the transaction specific

    triggers.

    ABS ROM basically produces a series of default scenarios.

    In each default scenario, the corresponding loss for each

    class of notes is calculated given the incoming cash flows

    from the assets and the outgoing payments to third parties

    and noteholders.

    The expected loss (EL) for each tranche is the sum product

    of: (i) the probability of occurrence of each default scenario;

    and (ii) the loss expected in each default scenario for each

    tranche.

    The EL of each tranche is associated with a particular time

    horizon in order to compare the EL to our benchmark for

    that time horizon (Moodys Idealised Expected Loss table).

    The relevant time horizon is the weighted-average life of the

    tranche, which is calculated based on the timing of paymentof principal to the tranche under each default scenario.

    We also run sensitivities to a variety of key asset inputs and

    structural features in order to test the sensitivity of the notes

    ratings.

    Key legal and operational risks

    As part of our analysis, we will review legal opinions to

    obtain external comfort in relation to key legal risks in a

    transaction. Each jurisdiction has different types of risk that

    need to be assessed but the three main legal issues

    commonly analysed in an unsecured consumer loan ABSinclude: (i) national consumer protection law; (ii) set-off

    risk; and (iii) commingling risk. In our analysis of the

    STRUCTURED FINANCE

    transaction, we will take into account any risk on which we

    have not received any legal comfort or that is not mitigated

    structural features.

    Finally, we will carefully assess the deal operational risk.2

    Indeed the performance of a securitisation also depends on

    the effective performance by various parties such as

    servicers, calculation agents, trustees and cash managers

    (i.e., operational risk). When not adequately covered, this

    risk may preclude the transaction from achieving the

    highest rating.

    Main Risks of Typical Transaction

    We believe the following are the main risk drivers in a

    consumer loan securitisation transaction:

    Portfolio Credit Quality: An accurate assessment of thecollateral credit quality is the first key element toproject the potential losses on the structured notes.

    Underwriting and servicing policies (originator

    specific) together with the current and forecast

    macroeconomic environment represent key elements in

    our analysis. Furthermore, specific loan characteristics

    (e.g., repayment method) may also affect the pool

    credit profile.

    Transaction Structure: Specific features make the dealstructure more or less efficient from an investor

    perspective. For example, a stringent principal

    deficiency ledger definition will lessen leakage of excess

    spread in case of performance deterioration or an early

    cash trapping trigger would ensure a quicker

    deleveraging of the transaction. When modelling the

    transaction, we endeavour to reproduce the main

    structural features described in the deal documentation,

    where possible .

    Counterparty Risk: We will assess whether each dealcounterparty has a clearly defined role and

    responsibilities. Specific roles (e.g., swap counterparty)are more sensitive than other, as such we carefully

    evaluate the level of delinkage of the transaction.

    Legal Risk: Finally we would assess the likelihood ofany legal issue to affect deal performance. The most

    common risks for consumer loan transactions include

    set-off and commingling risk, which we expand upon

    later in this report.

    1. Structural Features and Effect on CreditEnhancement Levels

    A typical consumer loan transaction would have the

    following structural features:

    Cash structure with quarterly paying notes with avariable interest rate

    Two distinct waterfalls (interest and principal) withsequential principal payment3

    Cash reserve to ensure a liquidity buffer and creditsupport

    Hedging mechanism to cover for potential interest ratemismatch

    More specifically, differing structural features within a

    consumer loan ABS transaction can have a significant effecton the ratings of ABS bonds and/or the levels of credit

    enhancement required for target ratings. Structural features

    that typically have a rating impact include:

    Transaction default definition Revolving versus static portfolio Early amortisation triggers Availability of excess spreadFor the purposes of our example below, we have used asimplified structure with the following characteristics:4

    Three classes of rated notes Linear amortisation with fully sequential payment of

    interest and principal

    Constant excess spreadTransaction default definition: In most transactions, the

    default definition is objectively defined (e.g., borrowers

    enter into default if they are more than six months in

    arrears). If the default definition is vague (e.g., at the

    servicers discretion), we will assume the default definition

    is long-dated. Long-dated implies a longer period in

    which excess spread is not used to cover defaults because

    these defaults have not been recognised. This assumption

    will typically result in higher amounts of credit

    enhancement required for a given target rating compared

    with a transaction where a tight default definition is used.

    Defaults need to be registered in the transaction before cash

    flows can be used to cover these defaults. This is often

    effected via the inclusion of a principal deficiency ledger

    (PDL) in the structure, whereby the principal balance ofdefaulted loans is debited against the PDL on each interest

    payment date and excess spread (if available) is credited to

    the PDL up to the amount debited. Excess spread credited

    STRUCTURED FINANCE

    to the PDL is used to purchase additional eligible assets

    during the revolving period and is passed through to

    noteholders during the amortisation period. The

    mechanism described is in place to re-balance any mismatch

    in performing assets and liabilities due to asset defaults.

    Consequently, the earlier the defaults are recognised, theearlier available cash flows can be used to fill the gap

    between the performing portfolio and the outstanding notes

    balance, thus avoiding excess spread leakage.

    Exhibit 1 shows the effect on the model output using: (i) a

    six-month default definition; and (ii) an 18-month default

    definition.

    * Additional credit enhancement required to achieve a Aaa model output on Class A: 2%.

    Revolving versus static portfolios: Unsecured consumer

    loans usually have relatively short terms (two to six years).

    As a result, most consumer loan ABS transactions have a

    revolving period during which incoming principalcollections are used to purchase new receivables rather than

    to amortise notes. Adding new receivables to the pool can

    result in portfolio credit deterioration if riskier assets are

    added. This risk may be partly mitigated by tight eligibility

    criteria so that the quality of added portfolios remains in

    line with that of the original portfolio. Among other things,

    eligibility criteria may stipulate the maximum sub-pool5

    weights in the total pool, limits to geographical

    concentrations, minimum seasoning, or may exclude the

    addition of delinquent receivables.

    Early amortisation triggers: These are typically linked to

    the portfolio performance and are common features used to

    mitigate investors exposure to worsening portfolio quality

    over the revolving period.6

    Exhibit 2 shows the impact on the model output for a

    hypothetical consumer loan transaction of: (i) the inclusion

    of a revolving period; and (ii) the introduction of early

    Availability of excess spread: Excess spread is typicallycalculated, and in fact modelled as, interest collections net

    of senior expenses (e.g., servicing fees, bank account fees)

    and interest paid on the notes. As interest rates charged on

    unsecured consumer loans are generally relatively high,

    excess spread is often an important source of credit

    enhancement. In certain transactions, excess spread is

    guaranteed via certain interest rate swap mechanisms.

    The following example (Exhibit 3) shows that the reduction

    of excess spread has a negative impact on all tranches and

    junior notes are more sensitive to excess spread levels than

    senior notes.

    The benefit to noteholders provided by excess spread can

    vary depending on the timing of defaults modelled. In

    order to test the robustness of ratings, we will run model

    sensitivities with different timings of default.

    2. Main Characteristics of Securitised ConsumerLoan Portfolios

    Exhibit 4 summarises the main characteristics of securitised

    consumer loan portfolios:

    EXHIBIT 4

    Main Characteristics of Securitised Consumer LoanPortfoliosa

    Loan Purpose

    Personal loans: Usually granted to individuals tobridge a temporary liquidity gap, for one-off largeexpenses or to refinanceb existing unsecured

    indebtedness.c

    Purpose loans (also known as point-of-saleloans): Loans originated at point of sale to financethe purchase of a specific item (e.g., vehicles,ddurable goods or furniture).

    Granularity The largest borrower generally represents amaximum five basis points (bps) of the pool, with

    the average loan size seldom exceeding anequivalent amount between 5,000 and 10,000.e

    Maturity Tenor is seldom longer than six years.f

    Amortisation Profile Predominantly French amortisation profile (i.e.,fixed instalment up to maturity date).

    Payment Flexibility Not a widespread feature in securitised pools. Theborrower may have the right to request asuspension of payment for a limited period (e.g.,suspending payments for up to three monthlyinstalments - payment holiday) or an extensionof the loan maturity date.

    GeographicalDistribution

    Countries portfolios are usually spread out acrossdifferent regions. A pools geographicaldistribution can have a significant influence on thecredit quality of borrowers if certain areas aremore susceptible to or more affected by amacroeconomic downturn than others.

    Origination Channel Loans are usually originated either by the lenderdirectly (branches) or by dealers. Direct channelorigination tends to result in better quality loanportfolios than portfolios originated throughbrokers. However, we seldom have access toperformance data split by channel of origination.

    a Exhibit 4 lists the most common characteristics of consumer loan portfoliossecuritised so far. Specific portfolio or loan characteristics - not listed in the exhibit -may require specific consideration and adjustments in our assumptions, in additionto those listed in this report. In such cases, a detailed description of our analysis willbe included in the relevant Pre-Sale Report/New Issue Report.

    b This product traditionally has not necessarily been marketed as a means ofrefinancing delinquent positions. Indeed, many lenders routinely offer those clientswith no negative credit records the option to consolidate different exposures to

    better manage their finances. In fact, most past consumer loan securitisations donot have collateral composed of re-performing unsecured loans or re-aged loans.

    c Unsecured loans granted to individuals where the loan purpose was to purchase orrefurbish residential properties or even purchase a commercial activity maysometimes fall under the personal loan category. This is the case most notably inSpain where, as a consequence, the maximum size of a securitised loan can exceed200,000.

    d Auto loans included in consumer loan portfolios do not usually benefit from anyform of security as the title of the vehicle remains with the obligor and it is notpledged/transferred in favour of/to the lender, hence the issuer.

    e Please note that securitised portfolios may occasionally include large-sized loans.For instance, the FTA Santander Financiacion-4 securitised pool included a 2.5million loan. These are clearly exceptions and typically require further analysis tounderstand the nature and credit risk of such outlier loans.

    f Exceptions to this are represented, for instance, by the Dutch deal Chapel 2007 in which the weighted-average original maturity of the pool was 15 years. (For more

    details please refer to Chapel 2007 pre sale).

    3. Our Modelling Approach to Rating ConsumerLoan Transactions

    The first step in rating a transaction backed by a portfolio

    of unsecured consumer loans is to parameterise the expected

    default distribution based on the historical performancedata, any appropriate benchmarks and any qualitative

    adjustments as further described below. We assume that

    defaults of a granular asset portfolio are lognormally

    distributed.7

    EXHIBIT 5

    Characteristics of a Lognormal Default Distribution

    To date, we have assumed that granular portfolio defaults

    are lognormally distributed.However, we note that one drawback of assuming that

    defaults follow a lognormal distribution is that they are not

    bound at 100% (i.e., default scenarios above 100% have a

    probability greater than zero under the lognormal law). As

    long as the mean default and standard deviation are

    relatively low, the probability assigned to these extreme

    scenarios (i.e., default greater than 100%) is close to zero.

    In contrast, when either the mean or standard deviation is

    high, extreme scenarios with default levels above 100% may

    be assigned a relevant probability. In such cases, we may

    adjust the distribution parameters and re-run the modelusing an inverse normal default distribution and compare

    the results.

    Exhibit 6 illustrates the shape of the lognormal distribution

    Each default scenario is then fed through a cash flow model

    (ABS ROMTM 8 or other excel-based cash flow models that

    reflect the structural features of the deal and run through

    cash flow allocations in each period during the transaction.

    The loss and life for each class of notes is calculated in each

    default scenario and a corresponding rating is derived.

    Key Asset-Based Inputs to the Model

    Default distribution: Mean default and standard deviation

    The lognormal default distribution for the relevant

    portfolio is defined by two key inputs: the mean and the

    standard deviation. From these two parameters, we derive

    the CoV, a measure of the portfolios volatility relative to

    the mean. This allows better comparison of the variability

    between different lognormal distributions.9

    Deriving the cumulative mean default assumption

    For each securitised pool, we typically receive historical

    performance data specifically, static cumulative default

    ratios reported by vintage of origination.10 This data should

    be as representative as possible of the product being

    securitised.11

    To be statistically relevant, each quarterly vintage should

    include a sufficiently large number of loans (typically at

    least 1,000 originated loans - please refer to Appendix 2 for

    a detailed description of the Moodys Data Template for

    consumer loan transactions). The historical data forms the

    starting point in defining the mean cumulative DP and

    CoV for the portfolio.

    Given that recently originated vintages tend to have limited

    data points, we extrapolate the default of these vintages to

    derive the expected lifetime mean cumulative default rate.12

    The average cumulative DP across the cohorts provides a

    starting point mean DP for the portfolio.

    This starting point means DP is then adjusted to take into

    account: (i) observed performance trends; (ii) portfolio

    composition; (iii) underwriting and servicing quality of the

    originator; (iv) internal scoring model PD assumptions; (v)

    amount of historical data provided; and (vi)

    macroeconomic factors.13

    i. Observed performance trends

    a) Performance trends in recent vintages

    b)

    : A

    worsening trend in the younger vintages could

    prompt us to increase the mean DP assumption.

    Conversely, a clear improving trend could prompt

    us to decrease the assumption.

    Dynamic delinquency data:

    us to adjust the mean default assumption. In

    general, increasing delinquencies would lead us to

    increase the mean DP assumption and an

    improving delinquency trend would likely lead us

    to adjust the mean DP downward.

    Early- and mid-stage14

    delinquency trends might not yet be reflected in

    the vintage default data provided, and could lead

    c)

    Unrepresentative vintages

    ii.

    : Certain cohorts of

    origination may be eliminated when calculating

    the mean DP if they are thought to be

    unrepresentative. For instance, vintages with very

    few points of observation, very low origination

    volumes or different underwriting techniques may

    not be relevant when deriving the expected mean

    default for a securitised pool.

    Portfolio composition:

    iii.

    If the securitised portfolio is

    composed of different sub-pools with different

    characteristics, we will ideally receive performance datafor each individual sub-pool (e.g., by type of

    product/origination channel). The mean cumulative

    DP may be calculated as a blend of each sub-pools

    cumulative default assumption based on the mix of

    each sub-pool in the portfolio. For revolving

    transactions, the mean DP assumed for subsequent

    portfolios added to the securitisation may be increased

    or decreased to take into account the possible

    migration in credit quality allowed by a transactions

    eligibility criteria.15

    Underwriting and servicing quality of the originator:

    We thus form an opinion on the originator/servicer

    quality and adjusts the mean DP accordingly. For

    instance, if an originator states that it has changed its

    strategy to target a vastly riskier section of the market

    (e.g., employees on temporary contracts), we will very

    likely adjust the mean DP upwards from the data-

    observed average. We will also compare the originators

    historical performance with historical data provided by

    its peers to better understand its risk appetite in thecontext of the relevant market. Appendix 1 provides

    further details on typical loan underwriting and

    servicing procedures and how we assess them.

    The quality of the lenders underwriting procedures a

    key component in our analysis is assessed during an

    operating review that we attend at the start of the

    rating process. Among other things, we are particularly

    keen to understand: (i) the originators target

    population and risk appetite; (ii) the predominant

    channel of origination; (iii) the size and trend of refusal

    rate (how many applications are rejected and the

    rationale); (iv) the originators underwriting

    mechanisms, their understanding of the target market

    and the interplay between risk and returns; and (v) thegrowth rate of lenders portfolio (i.e., fast growing

    portfolio volume could signal aggressive underwriting).

    iv. Internal scoring model PD assumptions

    v.

    : The majority

    of lenders use an internal scoring model to underwrite

    new loans, while some calculate a loans one-year

    default probability. If we have access to the securitised

    portfolios weighted-average default probability, it can

    be useful to compare this to our mean DPassumption.16 If there is significant divergence between

    these two values, we would endeavour to investigate the

    drivers of such gap.

    Amount of historical data provided:

    vi.

    In certain cases,

    the historical data provided may be extremely scarce.

    This might occur if the originator has only recently

    started originating the consumer loan product or if an

    originator has greatly changed its target market or

    underwriting strategy. In this latter case, any

    performance data relating to a previously marketed

    product or underwriting strategy would not be relevantto the transaction being rated. If there is limited

    performance data available, we would benchmark the

    portfolio against peers and take a conservative mean

    DP assumption for the pool.

    Macroeconomic factors

    Macroeconomic variables are a key driver of default risk

    in a consumer loan portfolio, even more so in Latin

    American countries that are usually subject to higher

    macroeconomic volatility than EMEA or Asia/Pacific.

    Moreover, we have observed that default rates are

    usually highly correlated with a countrys GDP growth

    rate, unemployment rate, and interest rate fluctuations.

    In a benign economic environment, defaults are mainly

    driven by idiosyncratic risks (e.g., divorce, health

    problems, deterioration in a servicers collection

    capabilities) whilst during a time of economic crisis,systemic factors such as general unemployment and

    personal bankruptcy levels, as well as wage growth,

    have a significant influence on a portfolios observed

    defaults. A rise in unemployment levels in a country

    will affect many debtors within a pool, and this risk

    driver tends to prevail over others.17 Consequently, our

    portfolios mean DP assumption would also factor in

    our expectation of likely future economic scenarios.

    Most likely, the mean DP assumption would be

    adjusted upwards if historical performance data

    provided covered a buoyant economic period whilstGDP was forecast to contract over the life of the

    transaction, resulting in an increase in the

    unemployment rate.

    : Historical portfolio default

    data applied to derive the mean DP assumption should

    ideally cover an entire economic cycle. However, as this

    is seldom the case, we may rely on other portfolios with

    data that covers a whole economic cycle to assess how

    default rates move as economic conditions change.

    Case Study: Spain

    For illustrative purposes, we consider Spain one of the

    main consumer loan securitisation markets in EMEA.

    In the following exhibits (Exhibit 8 and Exhibit 9), we haveplotted the problematic loans (PL) ratio for Spanish

    financial institutions consumer lending and other

    household lending (approximately three-month

    delinquencies) against GDP growth and the unemployment

    rate. The PL ratio observed in Q1 2011 (flat year-on-year

    GDP growth was recorded in this period, after a severe

    contraction) is around 3.5 times the median observed over

    the period 2000-2006 (an average yearly GDP growth rate

    of 3.6% was observed during this period), indicating that

    the PL ratio tends to be negatively correlated with GDP.

    On the other hand, as expected, Exhibit 9 shows a positive

    correlation between PL ratios and unemployment.

    If the portfolios provided default data shows a worsening

    trend due to a deteriorating economic environment, the

    portfolios declining credit profile will generally be capturedwhen extrapolating the default data. However, if the trend

    is recent and the extrapolation exercise does not result in a

    higher mean DP than generally observed over a benign

    economic period, we will stress the mean DP upwards,

    taking into account both the economic forecast and data

    from previous recessions.

    Deriving the Standard Deviation and CoV

    We use observed cumulative default curves to ascertain the

    standard deviation and hence the CoV of the lognormaldistribution. A higher CoV implies a fatter tail of the

    distribution (i.e., a higher likelihood of high default

    scenarios materialising).

    Generally, the CoV may be adjusted for the same reasons

    that the mean default is adjusted (as described in points (i)

    to (vi) above). The CoV is usually adjusted upwards to

    capture uncertainties in the economic environment at the

    time the transaction is launched, as well as to capture any

    lack of depth in the historical performance data provided.Similarly, when making qualitative adjustments to the

    mean default and CoV, we need to ensure that we do not

    over-penalise or double-count the impact of given factors by

    adjusting both the mean and the CoV.

    The following verification is appropriate to better

    understand whether the parameterisation of the lognormal

    distribution is appropriate and/or consistent with other

    rated unsecured and secured loan transactions:

    1. Benchmark the mean and CoV against assumptions used

    for other unsecured loan ABS and secured RMBStransactions. Regularly updated EMEA Consumer Loan

    Indices reports18 provide an efficient tool to benchmark

    performance assumptions against other securitised

    portfolios.

    2. Calculate the portfolio implied asset correlation19 and

    benchmark this against other similar transactions, as

    well as the Basel II standard. By calculating the

    portfolio implied asset correlation, we measure the

    degree of pair-wise linear correlation between assets in

    the portfolio. A high asset correlation means that

    defaults tend to cluster. As such, a high assetcorrelation implies a higher volatility in the portfolio

    default distribution, which would, in turn, lead to

    higher credit enhancement levels.

    Asset correlation allows us to benchmark different

    portfolios against each other using a single metric. A

    value that is considered relatively standard for

    consumer lending is 4.0%.This number corresponds to

    the asset correlation parameter for revolving facilities as

    defined in the Basel II Accord. 20 Although the assets

    analysed are not revolving facilities, we deem the

    underlying borrowers to be similar.

    In the following exhibit, we provide an indication of

    the CoV for different mean DPs if we set the asset

    correlation at 4%:

    Timing of Defaults

    Having determined the mean cumulative DP for the

    portfolio, we define a timing of default curve and enter it

    into the cash flow model. This curve describes the

    proportion of defaults that occur in each period modelled.

    The timing of defaults has an effect on the notes rating

    levels as it determines how many defaults will occur in a

    given period and, as such, how many of these defaults will

    be covered by available excess cash flow or spread.

    If defaults are modelled to occur when excess spread is at its

    lowest levels (often the case towards the end of a transaction

    when the portfolio balance has extensively amortised), fewer

    defaults will be covered by excess spread. Therefore, we

    tend to find that the EL on a note is higher when defaults

    are back-loaded in the cash flow modelling.

    Empirical evidence suggests that defaults tend to

    concentrate during the early life of the loan (i.e., the first

    12-24 months), gradually decreasing after this period.19

    However, due to the sensitivity of ratings to the default

    timing assumption, we often test a variety of default timing

    curves to measure the ratings sensitivities observed.

    Several default timing assumptions are shown in Exhibit 15.

    The solid line (base case) reflects a typical default timing

    curve observed for an unsecured consumer loan portfolio.

    Recovery Rate and Timing

    Typically, we give limited benefit to recoveries in

    modelling, due to the unsecured nature of the loans backing

    the ABS notes.22 Recovery rates are usually in the 0%-30%

    range and, as expected, generally lower than the mean

    recovery rates assumed for secured loans or leases (such as

    RMBS or auto ABS transactions). We use historicalcumulative recovery rates by vintage of default data

    provided by the originator/servicer as a starting point to

    determine the recovery assumption.

    The recovery rate assumption is necessarily a function of the

    specific transaction default definition, which generally

    varies across jurisdictions (see Transaction default

    definition).

    For instance, a shorter definition of default (e.g., 90 days)

    would typically be associated with a higher recovery rate, as

    opposed to a longer definition of default (i.e., 18 months).In fact, early defaults may be driven by a more temporary

    aspect (e.g., temporary liquidity shortfall) in such

    circumstances, the defaulted position may return to

    perform or the servicer may effectively recover the position

    through debt restructuring.

    Additional difficulties may arise when reviewing recovery

    data because:

    Recovery figures provided may include interest andfees, as well as the principal component of the loan. Asa result, inflated recovery figures may be reported (in

    some circumstances, recoveries in excess of 100% of

    principal outstanding).

    The defaulted loan may be restructured or sold, and arecovery value of 100% recorded. This is clearly

    misleading, as we have no assurance that the debtor will

    maintain the restructured repayment plan and thus

    make a full recovery23 or that the originator will always

    be able to sell this loan at par in the future. Structures

    can be sensitive to recovery timing, especially in highdefault scenarios, where the time lag between defaults

    and cash flows from recoveries may result in a cash

    shortfall in certain periods. We assume that recoveries

    are either spread out over a certain period (e.g., half

    occur in the first year and the remainder over the

    following two years) or concentrated in a given period.

    Economic downturn: in stressed economic times, theaverage recovery rate would be negatively affected. We

    stress the mean recovery rate observed to take into

    consideration this specific factor.

    The main factors that influence our assumptions on

    recovery timing include the efficiency of the servicers

    operations, its collection procedures and the historically

    observed speed of recovery.

    Prepayment Rate24

    and Asset Yield

    We are provided with dynamic25 historical prepayment data

    by the originator and we test different prepayment scenarios

    in the cash flow modelling. On the one hand, prepayments

    are generally higher in a decreasing interest rate

    environment or highly competitive market, where cheap

    refinancing is readily available. During economic recessions,

    tightening credit conditions tend to lead to a decrease in

    prepayments made by borrowers. Conversely, deal-specific

    prepayment rates may be driven up if lenders choose to

    restructure loans for commercial reasons and, as such,

    repurchase these loans from the securitisation vehicle.

    High levels of prepayments may depress the cash yield

    received in a transaction (and hence decrease available

    excess spread) if higher yielding loans prepay first, as

    debtors would have greater incentives to prepay when their

    debt burden is elevated or if competitors are able to offercheaper re-financing options.26 The higher the dispersion of

    the interest rates in the portfolio, the higher the impact of

    high-yield-loan prepayments on the available excess spread.

    We typically stress the available excess spread in the

    transaction if the portfolio has a widely dispersed interest

    profile (please see a simplified example in Exhibit 17).

    However, prepayments can also have a positive credit effect

    given that borrowers who prepay their debt in full cannot

    also default. In any case, we will take into account anyspecificity of the market under analysis. If prepayments are

    not particularly sensitive to changes in interest rates (e.g., in

    Latin America), we would not apply the above approach,

    but would assess, for instance, the impact that the ease of

    refinancing may have on prepayments.

    Once we have calculated the initial asset portfolios

    weighted-average yield, it can be entered directly into the

    cash flow model, which will make adjustments to the

    incoming interest collections for delinquencies and defaults.

    Alternatively, we may be provided with an initial portfolioyield vector based on scheduled amortisation. However, as

    discussed above, various factors including a portfolios

    yield dispersion, prepayments, defaults and receivables

    additions may cause yield to differentiate from the

    projections provided over the life of the transaction. As

    such, we will examine the dispersion of interest rates within

    a pool together with the relevant eligibility criteria27 in

    order to decide whether to use the flat-charged yield, a flat-

    stressed yield, the yield vector provided or a stressed yield

    vector. If we choose to model a stressed yield, we are

    effectively also stressing down the available excess spread.EXHIBIT 17

    How We Stress Portfolio Yield to Take Into AccountPrepayment Rates

    In a decreasing interest rate environment, high interest rate

    loans would tend to prepay more quickly than low interest

    rate loans.

    Having defined the constant prepayment rate (CPR)

    assumption (e.g., 15%), we will assume that the whole

    percentage is applied to loans that pay the highest rates and

    will consequently calculate the appropriate portfolio yieldhaircut.

    Please refer to the following example:

    % Portfolio % Yield

    yield 4% (these loans have, for simplicity, been sized to

    match the 15% CPR assumption). As a result, the portfolio

    STRUCTURED FINANCE

    would ultimately yield 3% (i.e., 15bps lower than the

    original portfolio).

    Portfolio Scheduled Amortisation28

    The final asset-based key model input is the portfolio

    amortisation profile. The initial portfolio amortisationschedule is provided by the originator. If subsequent

    portfolios are sold, we may either use the same amortisation

    profile as per the initial pool or simulate different

    amortisation schedules based on eligibility criteria. These

    vectors determine the principal cash flows to be received by

    the issuer in the absence of defaults and prepayments.

    Final maturity of the deal is given by the issuer and

    modelled accordingly. It usually falls a few years after the

    maturity date of the longest maturing loan. This gap takes

    into account the recovery lag of the latest defaults in the

    deal.

    The Cash Flow Model

    We aim to replicate the transaction structure in a cash flow

    model, such as ABS ROM. A simplified version of the

    model is available onwww.moodys.com.9.

    Once we have determined the asset-side modelling

    assumptions, other transaction-specific inputs need to be

    inserted into the cash flow model.

    Transaction expenses: These include (i) fees to be paid to

    transaction parties such as the trustee, cash manager, and

    servicer; and (ii) note coupons. We will stress the charged

    servicing fee upwards if the level is not in line with market

    rates, and we generally use a minimum servicing fee

    assumption of 50bps. This is to ensure that the transaction

    can withstand paying a market rate servicing fee if the

    original and cheaper servicing contract were to be

    terminated over the life of the transaction.

    Hedging: Interest rate swaps are modelled as relevant in

    the cash flow model and may impact yield and excess spreadassumptions.

    Triggers: When breached, these portfolio performance-

    based triggers result in early amortisation of the notes or an

    alteration of the priority of payments. Where the trigger is

    linked to a variable that we model (e.g., defaults or reserve

    fund levels), we can include this trigger in the cash flow

    modelling.

    Once all of the asset-side modelling assumptions and

    transaction-specific inputs are implemented, ABS ROM

    produces a series of default scenarios. In each defaultscenario, the corresponding loss for each class of notes is

    calculated given the incoming cash flows from the assets

    and the outgoing payments to third parties and

    noteholders.

    The expected loss or EL for each tranche is the sum product

    of (i) the probability of occurrence of each default scenario;

    and (ii) the loss expected in each default scenario for each

    tranche.

    The EL of each tranche is associated with a particular time

    horizon in order to compare the EL to our benchmark for

    that time horizon (Moodys Idealised Expected Loss table).

    The relevant time horizon is the weighted-average life of the

    tranche, which is calculated based on the timing of payment

    of principal to the tranche under each default scenario. In

    addition, we identify the default scenario under the current

    modelling assumptions under which each rated tranche

    suffers its first loss. An illustrative example is shown in

    Exhibit 18.EXHIBIT 18

    First Loss Suffered by Each Tranche

    The rating of each class of notes indicates the EL level for

    the relevant class of notes over the weighted-average life of

    the notes.

    As a further step, it is useful to ascertain the lowest default

    scenario in which each class of notes suffers its first loss, as

    well as at what speed the loss increases in each subsequent

    default scenario. We endeavour to publish a graph similar

    to Exhibit 19 in each New Issue Report, which associates

    the default scenario with the level of losses of each class of

    rated notes.

    Default Distribution and Expected Loss Level for EachTranche

    We also run sensitivities to a variety of key asset inputs

    (e.g., mean DP, CoV, prepayments) and structural features

    (e.g., turning triggers on and off) in order to test thesensitivities of note ratings. In particular, we publish

    STRUCTURED FINANCE

    Parameter sensitivities provide a quantitative, model

    indicated calculation of the number of notches that a

    structured finance security rated by us may vary if certain

    input parameters used in the initial rating process differed.

    Please note that rating models are just one tool used in the

    ratings process and are not exclusively relied upon to assign

    ratings. Ratings are determined collectively through the

    exercise of qualitative judgment by rating committees

    alongside the consideration of model results.

    4. Key Legal and Operational Risks Applicableto Consumer Loan Securitisation Transactions

    As part of our analysis, we will review legal opinions to

    obtain external comfort in relation to key legal risks in a

    transaction. Each jurisdiction has different types of risk thatneed to be assessed. Three main risks commonly analysed in

    unsecured consumer loan ABS are discussed below.

    Consumer protection laws

    Most jurisdictions have consumer protection laws in place

    to ensure that consumers are treated fairly by lenders. A

    lenders failure to comply with these regulations could

    potentially void the consumer loan contracts it has

    originated and borrowers could consequently withhold

    payments under the contract.

    We will rely on legal opinions, which provide comfort thatthe securitised credit agreements are highly unlikely to be

    challenged under consumer protection law. We would also

    rely on an originators representations and covenants as to

    the fairness of its procedures for dealing with customers,

    specifically in cases where the originator is highly rated and

    supervised by the central bank.

    Set-off risk

    Set-off risk arises if the loan originator who is a deposit-

    taking institution becomes insolvent. For instance, if a

    borrower holds deposits with the bank and also owes moneyto the bank under a loan contract, a borrower might be

    entitled to set off the deposit amounts he or she has lost

    against the outstanding loan amount. We would rely on a

    jurisdiction-specific legal opinion to understand whether

    borrowers have the right to set-off amounts against

    securitised loans and, if so, the amounts that could be set

    off. If borrowers set off amounts against a securitised loan

    receivable, this would translate into reduced collections for

    the ABS transaction.

    However, in certain jurisdictions, we expect that deposit

    guarantee schemes will ensure that consumers do not losetheir deposits following the insolvency of a bank (typically

    up to a certain limit). As such, potential set-off loss may be

    reduced and this is reviewed on a case-by-case basis.30

    If set-off risk is not fully mitigated through structural

    protections (e.g., reserved against on a dynamic basis), we

    will conservatively estimate the potential set-off exposure in

    modelling this risk. In modelling set-off risk, we use the

    originators rating to model the likelihood of originator

    default and will assume that all borrowers who are able toassert the right of set-off risk will do so following an

    originators insolvency. We typically assume that there is a

    50%-100% correlation between asset default scenarios and

    originator default.

    Exhibit 20 shows the incremental credit enhancement

    required to target Aaa ABS ratings for an Aa2-rated, Baa2-

    rated and B2-rated originator with a 10% set-off exposure.

    * Additional credit enhancement required to obtain a Aaa model output on class A** For lowly rated originators, Aaa(sf) would be achievable if set off exposure is fullycovered (i.e., via a dedicated reserve)

    Commingling risk

    If cash belonging to the issuer passes throughcollections

    accounts in the name of the originator/servicer, as part of

    our analysis, we must ascertain whether in an

    originator/service insolvency scenario, the deal would be

    exposed to the risk of either: (i) cash belonging to the

    special purpose vehicle (SPV) becoming unavailable for a

    given period of time (i.e., liquidity risk); or (ii) the SPVhaving only an unsecured claim against this cash in the

    bankruptcy estate of the originator/servicer (credit risk).

    Unless we are satisfied that the originator will not receive

    any collections after it becomes insolvent or that any

    collections received by it will be excluded from the

    insolvency estate, we generally assume that a certain amount

    of collections will be subject to commingling. The assumed

    amount of commingling loss is determined for each

    transaction and is based on the frequency of the transfer of

    collections from the originator/servicer account into the

    SPV account as well as the arrangements in place to ensure

    that borrowers stop paying into the insolvent servicers

    account and switch payments to either the issuer SPV or the

    STRUCTURED FINANCE

    successor servicers account. Assuming daily sweep of

    collections into the SPV account, we generally assume that

    a minimum of one month of collections will be

    commingled. However, this minimum will vary depending

    (among other things) on the means and frequency of

    payment of the borrowers in the pool and the country ofthe assets. Unless commingling exposure is suitably fully

    enhanced for, we model the rating impact, having regard

    for among other factors the originators senior

    unsecured rating.

    Collections may also be lost if the collections account bank

    holding the SPVs cash becomes insolvent. This risk is

    typically mitigated by the requirement that a bank holding

    any cash belonging to the issuer has a minimum required

    short-term rating of P-1. If the collections account bank is

    downgraded below this rating level, the servicer would be

    obliged to find another collections account bank or anunconditional, first-demand guarantee on its obligations

    provided by a P-1 rated institution.

    As far as EMEA jurisdictions are concerned, a detailed

    description of the risk and our approach on how to treat

    this risk can be found in our Special Report Cash

    Commingling Risk in EMEA ABS and RMBS

    Transactions: Moodys Approach, published in November

    2006 (SF85241).

    Operational risk

    The performance of a securitisation transaction depends not

    only on the creditworthiness of the underlying portfolio but

    also on the effective performance by various parties such as

    servicers, calculation agents, trustees, and cash managers

    (i.e., operational risk). When not adequately covered, this

    risk may preclude the transaction from achieving the

    highest rating. Please refer to Global Structured Finance

    Operational Risk Guidelines: Moodys Approach to

    Analysing Performance Disruption Risk (published March

    2011).

    5. Principal Sources of Uncertainty in thisMethodology

    The key uncertainties in rating unsecured consumer loan

    ABS arise from:

    Limitations of historical data:We are typically provided

    with static vintage default and recovery data covering five to

    seven years. We often do not receive data over a stressed

    economic period. Furthermore, historical data will not help

    predict very severe potential portfolio credit migration due

    to a change in a lenders underwriting practices.

    No third-party assessment of obligors creditworthiness:

    We are generally provided with the lenders historical

    portfolio data and, in certain cases, with the lenders

    expected portfolio PD and (loss given default) LGD.

    However, we very rarely receive borrower or portfolio credit

    bureau scores, which would allow us to benchmark aportfolios credit quality against others using a uniform

    metric.

    Originator governance influence on loan performance:Originators/servicers often retain the equity piece, and

    sometimes a number of subordinated tranches. Especially in

    revolving transactions, an originators underwriting risk

    appetite has a significant influence over the pool

    composition and its resultant performance. Originators

    with a vested interest in the transaction may have an

    increased interest in achieving a more conservative risk

    profile and maximising collections from the asset portfolio.If the originator/servicer has no exposure to the ABS

    transaction, investors may be more at risk of a worsening

    portfolio risk profile or less effective servicing.

    6. Monitoring a Consumer Loan BackedTransaction

    As a first step, during the rating process, we will review the

    transactcion reports as proposed to check all relevant

    information is included. Any perceived deficiency would bedisclosed to the market. It is essential we are provided with

    collateral performance data, including period and

    cumulative default, delinquencies, prepayments, recoveries,

    as well as data on loan restructuring and modifications.

    A description of the payment allocation is regularly

    provided, together with level of triggers and compliance

    with such triggers.

    We endeavour to monitor any rated transaction on an

    ongoing basis to ensure performance is in line with

    expectation. We will also check all supporting ratings.

    In addition, at least once a year, we perform a detailed

    review of each existing transaction to assess its performance

    and potential rating effects.

    Our quarterly EMEA Consumer Loan ABS Indices18 allows

    investors to compare the performance of any particular

    transaction with the market performance, as well as market

    performance of different jurisdictions.

    STRUCTURED FINANCE

    Appendix 1: Consumer Loan Underwriting andServicing

    Underwriting procedures for unsecured consumer loans

    tend to be more streamlined than those of other assets such

    as mortgage loans. This is generally due to the low amountstypically financed (on average equivalent amount of

    10,000) and the unsecured nature of these loans, which

    means that security does not have to be evaluated.

    A large part of the credit approval process is often carried

    out automatically, specifically by credit models developed

    by the lender. Manual intervention may be periodically

    requested, for instance in cases where the loan amount is

    unusually large.

    Underwriting procedures generally take into account:

    Borrowers repayment capability: This is assessed bychecking a borrowers credit history and outstanding

    debt as well as verifying his/her sources of income

    Scorecard results History of relationship with the lender (where relevant) Loan terms Product characteristicsThe adjudication process also aims to determine whether

    the borrowers credit profile is in line with the lendersdesired borrower credit profile.

    This is a function of each lenders risk appetite: lenders with

    large books and diversified business activities may be ready

    to assume higher risk, which is generally counterbalanced

    by higher pricing.

    A prudent lender will aim to continuously validate and

    adjust its credit model, in order to take into account

    changing economic conditions, applicant and product

    characteristics.

    Notwithstanding the substantial differences between anunsecured consumer loan and other loan products (e.g.,

    mortgage loans), these consumer loan products tend to be

    affected by systemic factors (macroeconomic environment)

    or life factors (e.g., death, health or divorce). However,

    the severity of the impact of such events on an unsecured

    consumer loan versus a mortgage loans performance may

    vary, as it is arguable that a borrower who has both anunsecured consumer loan and mortgage loan exposure

    would tend to pay off the mortgage loan in order to avoid

    the risk of house repossession. The above is clearly a

    function of the specific legal environment within each

    country.

    We also note that the credit assessment carried out by a

    bank before extending a mortgage loan is considerably more

    detailed than the analysis carried out when offering a

    consumer loan, given the larger amount and longer contract

    length of a typical mortgage. Indeed, for the lender, the

    impact of a consumer loan default would be less severe andcumbersome to manage than a mortgage loan default.

    We note that the purpose of a loan may play a significant

    part in determining a consumer loan portfolios

    performance. Personal loans tend to perform worse than

    loans granted to finance the acquisition of durable goods

    (e.g., household appliances). An unsecured new vehicle loan

    tends to perform better than a used vehicle loan, most likely

    a result of differing borrower characteristics.

    Furthermore, loan origination channel appears to be

    another driver of portfolio performance, with broker-originated loans showing worse performance than that

    recorded by loans originated at the lenders branches.

    On the one hand, as regards the servicing of consumer loan

    portfolios, the process tends to be generally less aligned

    across lenders, and there is generally a considerable reliance

    on external and specialised parties to manage early-stage

    delinquencies. Conversely, focusing on the lenders general

    response to a deteriorating performance due to negative

    economic environment, we note that there is a general

    strengthening of the early-stage delinquencies activity (such

    as the anticipated time of action), while, in some

    circumstances, loan terms can be renegotiated (such as

    lengthening the loan tenor).

    Appendix 2: Our Data Template for ConsumerLoan Transactions

    For the analysis of unsecured consumer loan transactions

    we typically requests the following:

    Historical information: Defaults and recoveries (vintagedata)

    Filters applied to obtain the data sample Data should ideally cover a full economic cycle Data sample should be representative of the portfolio

    being securitised. If possible, data samples should be

    split by channel of origination and type of product (or

    any other relevant variable impacting performance)

    Loans should be split by quarter of origination(vintage) in order to track the performance of eachvintage through time. Each vintage should contain

    enough loans for the sample to be statistically

    significant (as a general rule, at least 1,000 loans)

    If the transaction is multi-originator, each originatorshould provide its own performance data

    The vintages provided should cover the longest possiblematurity of the assets included in the pool

    Default definition and sources of recoveries should beincluded

    Performance data on defaultsThe static cumulative default rate exhibit should indicate

    the cumulative default rate for each period since

    origination. This rate is calculated as the ratio between the

    total outstanding amount of loans that have defaulted since

    their origination up to the relevant period and the volume

    of origination corresponding to the vintage under analysis.

    Performance data on recovery

    The static cumulative recovery rate exhibit should indicate

    the cumulative recovery rate for each period since default.This rate is calculated as the ratio between the total

    outstanding amount of recoveries received up to the

    relevant period (coming from the same vintage of defaulted

    loans) and the volume of default corresponding to the

    vintage under analysis.

    Historical information: Arrears information

    On a quarterly basis, ideally covering a full economic cycle.

    Ageing by bucket: e.g., 1-30 days overdue (first bucket), 31-

    60 days overdue (second bucket), and 61-91 days overdue

    (third bucket). This is calculated as the ratio between thetotal outstanding amount of loans in a certain bucket at the

    end of each period and total portfolio outstanding amount

    at the beginning of the period.

    Roll-rate analysis (i.e., percentage of delinquent receivables

    in one bucket (as previously defined) that passes to the

    successive bucket in the following month).

    Prepayment rates (CPR)

    On a quarterly basis, ideally covering a full economic cycle.This is calculated as the ratio between total principal

    prepaid during the period and the total outstanding balance

    of the portfolio at the beginning of the period.

    Appendix 3

    EXHIBIT 21

    Simplified Example: Derivation of Mean Default Rate andVolatility Assumption

    Let us assume that we have received the historical data as

    summarised in Exhibits 22, 23, and 24. We also assume

    that: (i) around 70% of the portfolio has been originated

    after 2006; (ii) the portfolio is highly granular in terms of

    debtor exposure and geographical distribution; and (iii) the

    portfolio weighted-average life is equal to two years.

    The cumulative mean default rate derived from the raw

    data depicted in Exhibit 22 would be around 7%, whereas

    the extrapolated mean default rate is equal to 10%.The

    higher value of the latter is the result of the worsening trend

    of the younger vintages. We will also take into account thefollowing elements to derive the mean PD assumption:

    i. The data set does not cover a full economic cycle.

    ii. There is a clear negative trend in the younger vintages.

    Vintages prior to 2006 reflect positive economic

    conditions, whilst new vintages show higher default

    rates due to stressed economic conditions. However,

    these vintages are still too young to allow for a

    meaningful result based on extrapolation over two

    years. The deteriorating trend can clearly be observed

    in Exhibit 23, in which vintages from 2006 onwardsexhibit higher default rates than the previous vintages

    over the same period following origination.

    iii. The macroeconomic forecast. If it is negative, this may

    further accentuate the negative trend.

    iv. The worse-than-average performance of an outstanding

    transaction with the same originator and servicer as

    shown in Exhibit 24.

    After consideration of these elements, we would modify the

    results obtained from extrapolating the historical data and

    would likely assume a mean cumulative default of 13%-15%.

    With regard to the volatility assumption, the CoV

    calculated incorporating the full data sample is 40%.

    However, if we only consider data from 2006 onwards

    (origination period that is more representative of the

    portfolio being securitised), the CoV decreases to 35%.

    Given the high granularity of the portfolio, the short

    average life and the fact that we have already applied several

    stressful adjustments to the mean DP, we would likely

    assume a CoV of 35%, which implies an asset correlationequal to 4.5%-5.0%.

    1 For example, Japan installment sales loan receivables are not specifically covered by this methodology. Analysis of portfolio made up of such assets would require

    (operational leasing)). Italian cessione del quinto (i.e., 20% salary assignment loans) and similar type of loans ( e.g. loans to employees of French electricity

    and gas companies ) also require further analysis of a set of risks and protective features not covered by this report (e.g. amongst others: the creditworthiness of the

    Sub-pools are generally made up of personal loans, purpose loans and unsecured auto loans.6 Most effective triggers are usually net excess spread trigger, unpaid PDL, and triggers linked to arrears levels.7 Please refer to The Lognormal Method Applied to ABS Analysis, July 2000.8 Moodys ABSROM v.1.0 User Guide, May 2006 available onwww.moodys.com. Please note that more recent versions of the model are used internally but

    are currently not publicly available.9 The advantage of using the CoV (instead of the standard deviation) is that the CoV is a relative measure, as opposed to an absolute value. All other assumptions

    being the same, a higher CoV implies a wider distribution, and therefore a higher credit enhancement.10 Cumulative defaults as a percentage of originated receivables balance for each cohort originated.11 Historical performance data provided should, where possible, relate to a portfolio with similar characteristics to those being securitised, including among other

    things uniform underwriting criteria, loan tenors and loan purposes. If this is not possible, proxies can be supplied, but greater uncertainties arising from this

    will likely be reflected via a qualitative adjustment to our assumptions.12 This procedure is fully described in our report Historical Default Data Analysis for ABS Transactions in EMEA, November 2005.13 An additional possible adjustment may be triggered by renegotiation limits included in the deal documentation. Generally, there are constraints on the servicer's

    ability to renegotiate loan terms and conditions, including maturity extension. For instance, the servicer may be able to renegotiate the maturity of only 2% of the

    portfolio and cannot extend it beyond the final maturity date of the deal. As such, no adjustments are required to Moodys assumptions. In the case of less strict

    renegotiation limits, we may adjust our DP assumption to take into account the potential higher volatility on the portfolio performance.14 Early and mid-stage delinquencies generally refer to 1- 60 days in arrears.15 More precisely, we typically derive the portfolio mean DP for revolving transactions assuming the worst possible portfolio composition given the eligibility

    criteria. For example, let us assume that the portfolio is made of personal loans (30% of total portfolio) and auto loans (70% of total portfolio), with a mean DP

    equal to 6% and 3%, respectively. The mean DP assumption for the portfolio securitised at closing will be 3.9%. However, if according to documentation,

    personal loans may come to represent up to 50% in the portfolios purchased during the revolving period, then we will assume a mean DP of 4.5% for such new

    portfolios.16 We expect internal scoring systems to have gone through validation processes (preferably by the central bank).17 Modelling Credit Risk of Portfolio of Consumer Loans, Madhur Malik and Lyn Thomas; 2006 CORMSIS-07-12. ISSN 1356-3548.18 Please refer to Moodys EMEA Consumer Loan ABS Indices, regularly published.19 Assuming that the portfolio defaults follow an inverse-normal distribution, the implied asset correlation can be derived from the following formula

    Where,

    p: mean default

    : standard deviation: asset correlation

    : standard bivariate normal cumulative distribution function20 Basel Committee on Banking Supervision, International Convergence of Capital Measurement and Capital Standards A Revised Framework, (2005), Bank

    for International Settlements.. Basel II determined asset correlation parameter for revolving facilities is 4%, whereas for other retail it is defined by a PD-

    dependent formula, the results of which range from 3% to 16% (the higher the DP, the lower the correlation):

    - 18 transactions outstanding: 8 closed pre-2008; 10 closed post-2008 (2008 included).

    - Eleven originators with consumer loan ABS outstanding in the market.

    - Average transaction size is 1 billion.

    - Ten transactions had their DP assumptions revised upwards in 2009/2010.

    - Increase in DP assumptions in Spain driven by stressed economic environment in 2008 and 2009.
