Securitization: Risk and Prospects

The basic motivation behind any Securitized transaction is:

Efficient Financing

Better Risk Management through risk transfers and delinking of credit risk of originator from

credit risk of asset

Improved Balance Sheet Structure removes illiquid assets, improves capital structure and

capital adequacy

The figure above depicts pictorially how various stake holders are involved and in very simple

language, securitization can be understood as conversion of existing illiquid assets like loans,

advances and receivables into tradable security. The basic benefit as highlighted above is that illiquid

assets are converted into marketable securities and thus provide alternate funding source. Any type

of assets with a reasonably predicted cash flow can be securitized. The nature and amount depends

on the risks of the securitization as determined by the Rating Agencies, Underwriters/PlacementAgents and Investors. The intention is to reduce the risks to the Investors and thereby increase the

rating of the securities ultimately lowering the costs to the Originator.

Current Indian Scenario on Securitization

Globally the securitization market is huge and for the financial year 2011-12, the numbers of

transactions were around 620 with issuance volume around $366 Bn. [1]

In comparison to global markets, Indian markets are miniscule, amounting to Rs 36,603 crore in

FY2011-12 even after growth of over 15% as compared the fiscal 2010-11, according to ICRARatings. [2]

The detailed guidelines for securitization were issued in Feb 2006, which is where RBI provided

details and criteria for true sale of assets in securitization. There were provisions for credit

enhancements to be provided either by banks or by third party credit enhancers. Post regulations, the

typical originators were transport companies, commercial vehicle and commercial equipment

companies.

Main asset classes in India securitization market:The main asset classes used in Indian markets are:

1. ABS (CV/CE) - Commercial Vehicle (CV) and Construction Equipment (CE) loans are the key

asset class accounting for two-thirds of the total ABS volumes. The main reason for such high

volume is long and comparatively stable track record of CV / CE lending in the country (also

demonstrated through good performance of the past pools). In addition the relatively larger

size of CV / CE loan portfolios in the industry have been the key factors for the popularity of

this asset segment in securitization.

2. RMBS- The number of Resident Mortgage- Backed Securitization (RMBS) issuances are theother products which consist of major securitization market.

The considerable jump in the volume in the last financial year in overall securitized issuances was

primarily due to the 26% surge in securitisation of retail loans, which consists of asset-backed

securitisation (ABS) as well as residential mortgage backed securitisation (RMBS). As per ICRA-

ASSOCHAM study during the financial year (FY) 2012, while the asset-backed securitization (ABS)

issues have increased by 58%, the residential mortgage-backed securitization (RMBS) registered

increase of 53%.

The main mechanisms used by investing banks have been direct assignments i.e., direct sale of a

selected l oan pool by the Originator to the Purchaser (or Assignee) together with limited credit

support, as against securitisation which involves the sale of receivables to a special purpose vehicle

(SPV) and issuance of Pass Through Certificates (PTCs) by the SPV. Over the past four years i.e.

since FY2009, about 75-80% of the total number of ABS and RMBS transactions has been in the

nature of direct assignment transactions, wherein no specific instrument is issued even as the


4/12

assignee payouts are rated. The main reason investing banks used securitized bilateral transactions

to acquire loan pools was to meet their Priority Sector Lending (PSL) targets. Another motivation for

outright purchase of loan by banks is the treatment on balance sheet, since PTCs by virtue of them

being investments would need to be marked to market, and loans and advances do not have this

requirement.A major factor of concern though is no participation by mutual funds investments. For instance, while

MFs can invest only in instruments , unlike banks which prefer to acquire loan portfolios outright.

There is some ambiguity regarding taxation on returns earned on these investments by MFs, which is

detailed further in the document. Accordingly, banks were typically the investors in these transactions.

Despite higher issuances seen in the year, the traditional obstacles to RMBS in India, viz., long

tenure of RMBS paper, the lack of secondary market liquidity, high stamp duty on transfer of security,

tenure uncertainty, interest rate risk and prepayment risk, continued to hinder the growth of thissegment. Nevertheless, regulatory requirements certain category of home loans qualify as priority

sector lending provide the motive for trading in home loans too. Some of these issues are detailed

again further in the document.

Though limited, but it is worth mentioning Indian governments efforts in terms of developing the

securitization at least for RMBS through National Housing Board. NHB has been playing a lead role in

starting up Mortgage Backed Securitisation and development of a secondary mortgage market in the

country. NHB launched the pilot issues of Mortgage Backed Securities (MBS) in August 2000 in theIndian financial market. Support to Mortgage Backed Securitisation has been a major policy initiative

of the Government as manifested in its National Housing and Habitat Policy announced in 1998. The

policy has enjoined upon National Housing Bank (NHB) to play a lead role in starting mortgage

backed securitisation and development of a secondary mortgage market in the country.

Latest RBI Guidelines (May 2012):

The RBI, on 7 May 2012, has put out the final guidelines on securitisation and direct assignment of

loan receivables. This is the first time the RBI has issued separate guidelines for Direct Assignmenttransactions. These guidelines are largely similar to the draft guidelines released in September 2011,

other than some differences the key ones pertain to Minimum Holding Period (MHP) requirement and

credit enhancement reset. Under the Guidelines, no credit enhancement is permitted for these

transactions. Given the prohibition on credit enhancement, the investing banks will be exposed to the

entire credit risk on the assigned portfolio, which most banks may not be comfortable with. Hence the

volume of such assignment transactions is expected to be severely affected in coming times. As


5/12

mentioned previously almost 75% of the market of securitized products was through direct

assignments last year and the trend was similar in previous years. But, with new regulation on

prohibition of credit enhancement through these transaction would impact the future market. On the

upside, the new MHP and MRR guidelines are slightly helpful. The MHP is a credit positive event as

it will establish some payment track record and provide some credible information on ability as well aswillingness of original borrowers. It is therefore expected that keeping in view the new Guidelines,

bilateral assignments are likely to be far fewer, as parts of erstwhile bilateral assignments market

would move to Securitisation route.

Risks related to securitization in India

Risks:

Typical risks associated with any securitized transaction are listed below. The risks particular toIndian market are detailed further in this section.

Risk retention rules

Conflict of Interest

Disclosure and Transparency

Credit ratings

Regulatory Capital

Compensation

Tax issues relating to PTC : The seemingly lack of clarity on true sale criteria set by RBI imposes

taxation issues. The regulation mandates that all risk and rewards related to securitized asset shall be

effectively transferred and originator has no control of assets. The main issue in securitisation is can

the originator derecognize the transferred assets? The RBI guidelines contradict with the accounting

guidelines laid by Indian GAAP and IFRS, RBI proposes gain to be amortized over the life of

securities issued or to be issued by the SPV, whereas accounting standards suggest recognizing

gains immediately along with some other complications, which exactly opposite of RBI treatment.

Another issue related to taxation is regarding income from pass through certificates (PTCs). The tax

authorities contest that interest income should be regarded as business income of the trust and

taxed at maximum marginal rate. The SPVs in turn pass tax to investors i.e. mutual funds that are

basically exempt from tax. The mutual fund houses contested it with the courts and the Mumbai high

court issues a stay providing a huge relief to the investors but its a matt er of concern for MFs to

invest in securitized products. Some industry experts believe that determinate trust structure and


6/12

revocable trust structure as the twin defenses to the current tax issues facing securitisation. The

explanation of such structure is beyond the scope of this document.

Legal Issues: As applicable to tax consideration, the categorization of securitized transaction as true

sale has many legal impacts and along with it, the next major question is what is the applicablestamp duty and other taxes. Stamp Duties on transfer of assets in such transactions can often make

a transaction impractical. The Working Group of RBI has recommended a uniform rate of 0.1% duty

on all transactions, which is still not approved.

Listing of PTC: Another big open ended challenge is whether PTCs can be listed or not and it still

remains an unresolved issue. The debt security as defined under FII Regulations, include

Securitisation instruments or not too needs clarification and these uncertainties will always hinder

growth of securitized transactions in India.

Lack of Debt Secondary Market: The demand for trades for PTCs as well as other securitized

securities can be seen as a proxy of corporate bond market. The primary market for corporate debt is

mainly dominated by private placements (93 per cent of total issuance in 2011-12) as corporates

prefer this route to public issues because of operational ease, i.e., minimum disclosures, low cost,

tailor made structures and speed of raising funds. This has impact on other fixed income products

and unless this market grows, other products will not see further growth. Corporate bonds issued in

India usually carry a rating of AAA indicating lack of interest in bonds of lower rated borrowers in thedebt market. One way to further develop this market is to come up with different products for different

investors. Tranching is one mechanism to create products for different appetite customers, where a

specific class of bonds within an offering wherein each tranche offers varying degrees of risk to the

investor. Most ABS and RMBS transactions in FY2012 had simple structures with a single tranche

(while some transactions had two tranches), and the credit enhancement in the structures was

primarily in the form of cash collateral.

Further details of tranching is discussed in Annex-I.

Prospects of Securitization:

As briefly mentioned in the beginning of this write-up, the biggest benefit of securitization is spreading

of risk and greater market participation. Once the securities are available for trade it helps to not only

increase the liquidity but also helps to determine the market price. A market for Mortgage backed

Securities (MBS) in India can help large Indian housing finance companies (HFCs) in churning their


7/12

portfolios and focus on what they know best i.e. fresh asset origination. Indian HFCs have traditionally

relied on bond finance and loans from the National Housing Bank (NHB). MBS can provide a vital

source of funds for the HFCs. Another major benefit is lowering of mortgage rates, while individual

rates are still largely tied to a person's credit rating; mortgage rates as a whole are made lower

because securitization allows lenders to reduce costs. Therefore the advantage of securitization formortgage holders is that a more liquid mortgage market and a spreading out of risk eventually lead to

lower interest rates on home loans.

In order to further develop and build a successful securitisation environment, the major requirements

are:

Robust financial infrastructure

The Legal Environment

The Accounting Environment

The Regulatory EnvironmentThe Taxation Environment

Back-office Systems

Legal issues concerning Stamp Duty, Registration Act, Tax law, RBI Regulations, SEBI rules which

are not addressed in the current regulations sufficiently. The coordination between these laws is very

important to encourage the securitization transactions in India. Hence, the regulatory framework must

be framed to be a workable scheme of law. Apart from domestic legal issues, it is important to have

the law feasible and in coherence with the international standards, so that in future when the law on

securitization widens its horizon, there will be no difficulty in its transition.

It can be concluded that a well-developed securitization market can help in many ways including but

not limited to:

(i) enabling efficient allocation of funds,

(ii) facilitating infrastructure financing,

(iii) improving the health of the corporate balance sheets,

(iv) promoting financial inclusion for the Small and Medium Enterprises (SMEs) and the retail

investors

Therefore securitization can play a huge role in financial markets for diversifying risk, enhancing

financial stability, and for better matching of risk-return preferences of the borrowers.

Annexure - I

Tranching A primer

1. Objective

Financial institutions and investors can realise many benefits by using securitized products providedthat proper regulation and monitoring mechanism is in place. Hence, Indian financial institution should

actively trade in securitized products. Objective of this exercise is to find out how securitization can be

made more attractive to Indian investors and crate primary as well as secondary market of securitized

products in India. Though there are few extrinsic bottlenecks like regulations, taxation etc., banks and

SPVs can use tranching as a tool to make securitize product attractive to different kind of investors

by fulfilling specific needs of target investor group.

Through tranching, asset classes with different level of risk and return parameters can be created tofulfil investor needs. Senior tranch can have higher credit rating suitable for pension fund, insurance

companies etc., who are required to invest in investment grade securities by law. In this exercise a

pool of home loan was taken as underlying asset and divided the risk and return in three (3) tranches.

Return of most senior tranch resembles return of fixed deposit products. The middle tranch resemble

risk and return parameter of equity investment and the most junior tranch got highest credit risk with

return higher than equity investment, something in which Hedge funds might be interested.

Through this exercise analysis is performed to match risk-return profile expected by different types ofinvestors and assign appropriate credit rating to tranches to make securitized product more attractive

to Indian Investors.

2. Approach

The attached excel demonstrates the analysis of risk and return from a pool of mortgage backed

asset as divided it into 3 tranches resembling return form fixed deposit (Tranch A), equity (Tranch-B)

and high risk investment (Tranch C).

For the purpose of quantitative analysis, following variables are used. Variables can bealtered to analyse their impact on overall tranching framework.

Net Loan: The total loan amount of underlying mortgage asset at the beginning of the

contract. It is assumed initial loan amount to be $10 Million.

Maximum Loss Giving Default: This is the maximum principal amount which might be

written off due to credit default. Though the default rates are high, banks usually recover 60%


9/12

of the defaulted principal and rest 40% principal is written off. This variable represent the

actual loss happened during the lifetime of loan.

Interest Rate: It is the interest rate paid by the borrower of the underlying asset. Assumed

12.5 % interest as typical interest rate of mortgage in India. Percentage of Principal Amount: This variable indicates % principal contributed by every

tranch. This has been taken so that sum of the % of all 3 tranch should equal to 100% always.

For calculation it is assumed that 50% principal contributed by Tranch-A, 30% by Tranch-B

and rest 20% by Tranch-C.

Tranch Interest Rate: Interest rate promised to investors of different tranch depending on

their risk profile. The interest is calculated every month on principal outstanding at the

beginning of the month after accounting for pre-payment and default.

3. Assumptions

Following Assumptions are made for the purpose of quantitative analysis

The underlying loan will be re-paid fully within 5 years.

Any pre-payment will be repaid to all 3 tranches equally. So all 3 tranches assume equal

reinvestment risk. Pre-payment amount will be deducted from principal every month.

Tranch C (the most junior Junk Bond tranch) assumes initial default risk. Principal of Tranch-

B will be impacted only after principal of Tranch-C cease to exist. Similarly principal of Tranch-

A will be impacted only after Tranch- Bs principal is exhausted. Defaults are assumed to be uniformly spread over 60 months.

SPV charges 15 basis point as service fees for facilitating the securitized transaction.

Originator charges 20 basis point as service fees for facilitating collections etc.

4. Analysis

4.1 Tranches

To depict how principal, interest etc. are changing in every period due to pre-payment and defaults,

calculation of every tranch for all the periods during life(60 months in this case) of the loan aredepicted. Change in every tranch is shown in a set of columns. Meaning of each column and

approach used for calculation is given bellow

Period: This is the indicator of age of the loan in months. As our security period is 60 months,

period starts from 0 (beginning of the security) and ends at 59. A row corresponding to a

period indicates status of the tranch at that period.


10/12

Initial Principal: Principal amount of a tranch at the beginning of a period after deducting

prepayment and default occurred in the previous period. Interest paid to a tranch in a period is

calculated on the outstanding principal at the beginning of the period. Initial principal at the

following period is same as principal left at the end of previous period.

Interest Paid: Amount of interest paid to a tranch at any particular period. Interest amount is

calculated according to promised interest rate and the initial principal in the tranch at the

beginning of the period.

PMT : This is the per month payment (consist of interest as well as principal) as received by a

tranch considering initial principal, promised interest rate and number of period left for the

security to mature. Excel PMT function is used to calculate this.

Principal Paid: This is the amount of principal paid every period as estimated by PMT

calculation. This is calculated by deduction interest amount from corresponding PMT value.This column doesnt consider any pre -payment or default.

Principal Left: This column contain amount of principal left in every tranch at the end of a

period. To calculate this column, deduction of Principal Paid in a period from Initial Principal

of that period is done. Also deduction of pre-payment amount assigned to the tranch is done.

If principal of subordinate tranches are exhausted due to credit default, then immediate senior

tranch start absorbing any further loss due to default. Also the default amount was deducted,

as well to calculate principal amount left in a tranch.

Investor Got Back: This is the amount that investors of a tranch got back in a period. Thiswas arrived by adding pre-payment amount allocated to a tranch with PMT amount.

4.2 Cash Flow

This worksheet matches cash in-flow from the underlying loan with cash out-flow to different tranches

for every period. Difference between total cash in-flow and out-flow can be source of revenue for

SPV.

4.3 Sensitivity Analysis The worksheet Sensitivity Analysis depicts how net cash flow of a tranch will be impacted due to

change in different economic parameters. 3 factors are used Interest Rate, Prepayment Rate and

Default Rate as these factors are most susceptible to change in economic climate and will severely

impact return realised by a tranch.

Sensitivity analysis shows that the most junior tranch start losing money as soon as loss giving

default become 7.5% of the original principal.


11/12

4.4 Default Rate

Poisson distribution is used to calculate probability of default. It is assumed that on an average loan

consist of 30% of the principal amount will be defaulted. The first column contain % of principal

amount that will be defaulted and Probability of Default column contain cumulative probability thatdefault rate will be less than the said principal %. The last column contains loss giving default as % of

original principal amount. Considering 40% of the defaulted principal is written off, it can be concluded

with 80% confidence that even with 10% average default rate, the most junior tranch will be able to

recover its principal.

5. Conclusions

From quantitative analysis (Please refer to the attached excel) it can be conclude that tranching will

help to grow securitization market in India by fulfilling appetite of different types of investors even after

providing margin to originator / SPV. With realistic assumptions, outcomes of quantitative analysis are

In most optimistic scenario with no default and no prepayment the speculative tranch earn as

high as 17.8%, equity tranch earns 13.8% and fixed deposit tranch earns 10.75%.

In a more likely scenario where it is assumed 5% loss giving default and 10% pre-payment

risk, speculative tranch annual IRR drop to 6.38%. This was computed with 86% confidence

that loss giving default will be less than 5% and realised return will be higher.

In worst case scenario with 99.9% confidence level and 9.2% loss giving default, speculative

grade tranch may lose 3.4% while other tranches still realise positive return.

So from the above analysis, it is evident that tranching will help to offer different grades of

investment option and will help further grow the securitization market in India.
