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%

Mortgage Backed Securities (RMBS) - 1

RMBS Asset analysis

Moody’s Individual Loan Analysis – “MILAN”

Is a Scoring Model,

– Each single loan compared to a benchmark loan

– Adjustments for deviations from benchmark

– The total portfolio to a benchmark portfolio

Result of in depth analysis and comparison of major

European RMBS markets

Standardised, but addresses country specific features

Able to analyse multi-seller/country pools

“MILAN” Adjustments – Why?

Captures additional default, loss and volatility drivers

(deviation from benchmark and “no data“)

For each single property

Account for certain loan aspects

Based on borrower characteristics

Addressing seasoning and performance aspects

For originator/servicer quality

Diversification issues of the portfolio

Adjusting for structural aspects

Asset Backed Securities (ABS) - 4

Asset Analysis: Adjustments to Distribution Parameters

Possible for both parameters

– Trends impact Mean

– Uncertainty impacts Standard Deviation

Pool dependent

– Composition (asset criteria, limits)

– Age of assets (“Seasoning“)

Originator/Servicer dependent

– Performance trend

– Change of credit policy (underwriting, servicing)

19

Asset Backed Securities (ABS) - 5

The Model: Links Assets and Liabilities

Standard model (“ABS ROM“) – technical frame

– Models deal specific features

Reflection of cash flow structure (“Waterfall“)

Beside distribution, other inputs:

– Timing of defaults/losses

– Recovery rates and time of recovery

– Amortisation profile, transaction expenses

– Triggers (variety possible, specific impact )

Issues in New

Markets

21

Issues to Watch: Securitisations In New markets

Legal and regulatory environment

Organisation of financial sector

Interest and currency exchange rate risk

Sovereign rating

Systemic risks - Local Currency Guidelines (LCG)

Objectives of issuers and investors

Extent of government support

Importance of Legal Environment

Bankruptcy laws – true sale, claw back, commingling, set-off

Security interest and claim priorities

Enforceability

For future flow deals – isolation of cashflows abroad

Consumer protection laws/policy

– notification to borrowers

– data disclosure

– usury

Tax issues: corporate, transfer, withholding or other

Specific securitisation law

23

Two Main Elements That Could Reduce the Rating

Systemic risks

– Include financial stability, legal, regulatory, quality of data, risk of fraud

– Affect ALL debt issued in the country, whether LC or FX

Transferability and Convertibility risk

– Address the potential impossibility of paying FX to offshore investors in the event of moratorium coupled with FX restrictions by the government

– Affect only FX debt

Piercing the Sovereign “Ceiling” – How?

Aaa

A rating can exceed the LCG only by an external guarantee or insurance “wrap”

Country’s local currency Guidelines

(LCG)

A1 for Russia Sovereign ceiling may be pierced based on: (1) highly rated local currency obligation combined with (2) liquidity facility or political risk insurance

Credit

Enhancement: subordination, reserve, excess spread

Final Thoughts

28

Russia – Outlook for Securitisations

Tremendous growth of consumer and mortgage lending will continue to generate future MBS/ABS

Improvements of laws/regulations to facilitate securitisations should relieve existing uncertainties

Deal flow is expected to expand to other asset classes

– CDOs, leases, SMEs, infra-structure

Local securitisations are expected shortly (MBS)

Multi originators structures

29

Ten Commandments – Preparation For a Transaction

1.

2.

Discuss legal issues EARLY with lawyers & rating agency

Decide (and discuss with us) rating target

3.

4.

Evaluate what enhancement/structure may be needed

Prepare portfolio data, including data format

5.

6.

Organise historical performance data

Consider back-up servicer

7.

8.

Determine structure

Assess external support (PRI, wrap, guarantee)

9.

Plan deal timetable reasonably

10.

Prepare strategy for future transactions
