Moody’s Rating – Expected Loss

Ratings measure credit risk

Probability of a default

Severity of a loss

Expected loss = Probability of default x Severity

Example:

Prob. Def. = 5%

Severity of Loss = 20% (recovery rate = 80%)

EL = 5% x 20% = 1%

– And, if the average life of the security is 6 years…

Rating SME transactions

13

What are SMEs ?

Enterprise classification scheme from the EU:

– micro, small, medium-sized SMEs based on headcounts annual turnover or annual balance sheet total

Basel II:

– Corporates with total assets or an annual turnover below EUR 50 million, either classified as retail exposures or corporate exposures

Entities of all sizes are included in SME securitisations

Moody‘s uses the SME definition of the originating bank

14

Common Framework for risk heterogeneous SME portfolios

Portfolios may contain less than 100 obligors or many 1000s of obligors

Portfolios with many 1000s of obligors can show concentrations in terms of:

– Regions, industry, collateral types

– Effective number used as measure of granularity

15

Determining the methodology: default distribution

Concentrations in terms of obligors, industries or regions:

Key element of analysis is to find appropriate default rate distribution

Monte-Carlo simulation: Moody’s CDOROMTM

or STARFINDERTM

Granularity of the SME portfolio:

Inverse Normal distribution

16

Parameters that need to be estimated

Default rate:

– Distribution parameters: mean and volatility

– Timing of default

Recovery rate:

– Distribution parameters: mean and volatility

– Correlation parameters

Prepayment rate

17

Sources of information for our assumptions

Historical information (quarterly cohort data) easy and direct estimation of the expected cumulative

default rate

Originator’s internal Masterscale (if validated) and/ or RiskCalc expected default frequency

Country specific statistical information for SMEs

Benchmarking with similar deals + Moody’s corporate ratings/outlooks

Other qualitative and pool-derived aspects

1) and/or 2) tuned by the rest of sources

18

Limitations on historical information (DR & RR)

Lack of representation of historical sample for securitized pool

Historical period does not cover a full economic period + real estate crisis

Lack of granularity for some vintages

Observation period shorter than the term of the loans

Distortions caused by refinancing/restructuring

Historical information needs often to be complemented with other sources of

information

19

Default Rate analysis: Mapping Analysis

Infer the credit quality of a portfolio from the analysis of the originator’s internal rating system based on:- Originator‘s internal Masterscale (1 year- expected PD)- Observed yearly rating migration matrices;

Moody‘s KMV RiskCalc Results are compared to the Moody‘s idealised default probabilities

Determination of expected cum DR over the time horizon for the deal (i.e. WAL) based on Moody’s idealized cumulative default rate table

Ideally based on a combination of different sources & approaches

20

Default rate Standard Deviation

Historical information allows an easy and direct estimation of the DP standard deviation

If meaningful historical analysis is not available or portfolio shows concentrations → estimate on the basis of correlation parameters

– Global correlation: driven by geographical concentration

– Intra-industry correlation: driven by industry concentration Stress applied for high industry-concentrated

portfolios

21

Recovery Analysis

Moody’s moves from a fixed recovery to stochastic recoveries

input needed mean RR, standard deviation of RR, correlation between RR, correlation between DR and RR

For concentrated portfolios, Moody’s adopts a Beta distribution applied to each defaulted asset

For granular portfolios, Moody’s uses a Normal distribution applied on a portfolio basis

Moody’s uses a recovery distribution

22

Source of information for Recovery Analysis

Usage of historical recovery data

Originator’s Internal loss given default (LGD) estimations (if validated)

Collateralisation ratios and type of collateral on a loan-by-loan basis for the securitised portfolio. Analysis for mortgaged properties:

– Type of property (residential vs. commercial) / occupancy type (owner occupied vs. income producing real estate)

Detailed information on RR is important

23

Ideally securitised pool information needed:

Criteria used to select the portfolio

Amortisation profile

Spread vector

Loan-by-loan information with:

borrower information (e.g. group, type, industry)/ loan

characteristics (e.g. purpose, outstanding, amortization,

interest rate, etc.)/ collateral information / originator’s

internal estimations /behavioural data (e.g. arrears status)

Moody’s would like to see a detailed description of the loans securitised

24

Moody’s Guidelines for Operational Reviews

Purpose and scope of on-site Moody’s operational reviews is to

understand

- the Business of the originator;

- Risk (especially credit) management,

- Product types and characteristics,

- Origination & monitoring process & Collection and recovery

processes including the internal rating systems (PD and LGD)

Key aim is to understand originator’s business

25

Analytical tools

CDOROMTM: default and/or recovery distribution for concentrated portfolios

STARFINDERTM : obtain default distribution for portfolios not homogeneous in terms of size or credit risk

ABSROMTM: cash-flow allocation model

– Add-hoc cash flow models: deal specific aspects not incorporated in ABSROM

RiskCalcTM: web-based analytical solution for estimating default risk for privately held firms

– The model produces forward-looking default probabilities, as well as implied credit ratings for each obligor

26

Obtaining representative rating

27

Suggestions – Early Preparation For a Transaction

Discuss legal issues with lawyers & rating agency

Decide and discuss rating target

– See what enhancement/structure may be needed

Prepare portfolio data, including data format

Prepare historical performance data

Consider back-up servicer

Determine structure

– External support? (PRI, wrap, guarantee)
