Securitisation process can be perceived as a two-stage process.

First stage: Transfer of mortgage debt from the primary lending institution (Originator) to a Special Purpose Vehicle (NHB SPV Trust set up by NHB through declaration) with or without the underlying security.

Second stage: The mortgage debt so acquired will be converted into tradable debt instruments (say in the form of Pass Through Certificates) without any recourse to the originator or the SPV.

Securitisation of Mortgage Debt : NHB SPV may purchase and convert the housing loans into securities/ PTCs concurrently and issue them in the capital market for investment by investing institutions.

Execution of Memorandum of Agreement with NHB
Based on the willingness to sell or securitise its portfolio of housing loans, the Primary Lending Institution is required to enter into an umbrella agreement (called Memorandum of Agreement) with NHB to sell/securitise its portfolio of housing loans. The Memorandum of Agreement encapsulates the entire MBS transaction and entitles NHB to take necessary steps to purchase or securitise an identified pool of housing loans, including circulation of the Information Memorandum and collection of subscription amount from investors, as the case may be.

Selection of Pool of Housing Loans
The pool of housing loans would be selected by the Primary Lending Institution from its existing housing loans based upon a ‘pool selection criteria’.


The home loans should satisfy the following standards for being considered for selection in the Mortgage Pool offered for securitization:

  • The borrower should be individual(s).
  • The home loans should be current at the time of selection/securitization.
  • The home loans should have a minimum seasoning of 12 months (excluding moratorium period).
  • The Maximum Loan to Value (LTV) Ratio permissible is 85%. Housing loans originally sanctioned with an LTV of more than 85% but where the present outstanding is within 85% of the value of the security, will be eligible.
  • The Maximum Instalment to (EMI) to Gross Income ratio permissible is 45%.
  • The loan should not have overdues outstanding for more than three months, at any time throughout the period of the loan.
  • The Quantum of Principal Outstanding Loan size should be in the range of Rs.0.50 lakh to Rs.100 lakhs.
  • The pool of housing loans may comprise of fixed and/or variable interest rates.
  • The Borrowers have only one loan contract with the Primary Lending Institution (PLI).
  • The loans should be free from any encumbrances/charge on the date of selection/securitization. The sole exception to this norm being loans refinanced by NHB (In such cases, the loans may be securitised subject to the originator substituting the same with other eligible housing loans conforming with the provisions of the refinance schemes of NHB).
  • The Loan Agreement in each of the individual housing loans, should have been duly executed and the security in respect thereof duly created by the borrower in favour of the PLI and all the documents should be legally valid and enforceable in accordance with the terms thereof.
  • The Bank/HFC has with respect to each of the housing loans valid and enforceable mortgage in the land/building/dwelling unit securing such housing loan and have full and absolute right to transfer and assign the same to NHB.
The Pool selection criteria may be modified by NHB from time to time at its sole discretion.
Submission of Pool Information
The Primary Lending Institution will be required to submit loan details relating to the pool as under (in prescribed formats attached).Due Diligence Audit
The Primary Lending Institution will get a due diligence review of the loan accounts conducted by Statutory Auditors of the Company or a firm of Chartered Accountants acceptable to NHB and shall submit a due diligence audit report to NHB after execution of the MoA certifying the following:-
  • Each of the housing loans in the pool conforms and satisfies the selection criteria laid down by NHB.
  • All the information furnished by the Primary Lending Agency to NHB with regard to the Borrower of the said agency is true and correct.
  • All the documents connected with the pool of housing loans proposed for sale to/securitisation through NHB are legally valid and enforceable and the said agency has good and assignable right to each of the housing loans free and clear of any set off, cross-claims, demands, encumbrance, equity, pledge, charge, claim or security interest thereon.
  • None of the housing loans has been sold, assigned, transferred or pledged to any person and the HFC is sole legal and full beneficial owner of these housing loans and has full right to transfer and assign the housing loans to NHB.
Valuation of the pool and Consideration of Assignment
NHB will consider making payment of purchase consideration to the Primary Lending Agency under the following methodology, with a view to obtain a sound and efficient pricing structure to the benefit of originators:(i) Par Pricing Methodology:
The consideration payable to the Primary Lender for transferring the pool would be equal to the total future outstanding principal balances of the individual loans on a Cut-Off Date.(ii) Premium Pricing Methodology: The consideration paid to the Primary Lender for transferring the pool would be decided and paid on the basis of discounting of future stream of net cashflows relating to the pool. It shall normally be higher than the total outstanding principal balances of the individual loans on a Cut-Off Date as the discounting rate used shall be lower than the weighted average coupon of the pool.(iii) Discount Pricing Methodology: The consideration paid to the Primary Lender for transferring the pool would be lower than the total outstanding principal balances of the individual loans on a Cut-Off Date as the discounting rate used shall be higher than the weighted average coupon of the pool due to higher risk perception.
Salient aspects of valuation:
  • The outstanding principal of the underlying home loans should not be less than the face value of the RMBS papers.
  • Pool Receivables: The HFC shall assign, transfer and convey to NHB (either in its corporate capacity or in the capacity of Trustee) for securitization the balance outstanding principal of these housing loans as on the cut off date and all future interest due thereon together with all its other rights, titles and interest in relation thereto and in the mortgage or other securities therefor.
  • As per the structure of the arrangement between NHB and the PLI, interest differential portion of the pool (i.e. Weighted Average Coupon of the pool less the Total Cost of the Transaction including coupon interest payable to the buyer of housing loans/investors in MBS, as the case may be), may be structured as continuous stream of subordinated cashflows in the form of either an “Excess Servicing Fee” or “Income on Investment in a particular class of MBS or in some other form.

In respect of (ii) and (iii) stated above, the net cashflows shall be arrived at by deducting the recurring expenses such as rating surveillance fee, trustee fee, registrar’s fee, listing fee, audit/out-of-pocket expenses, and any other form of credit enhancement measure as decided in the structure, from the gross cashflows. The discounting factor shall be determined on the basis of some realistic assessment of the prevalent rate of interest in the debt market in respect of similarly rated papers as well as risk being transferred under the transaction and the risk premium perceived thereagainst, including assessment of the capabilities / credit-worthiness of the service provider.
NHB will not purchase any overdue EMIs or penal interest/out-of-pocket expenses outstanding in the originator’s books as on the cut-off date. These amounts as and when collected from the respective borrowers will be retained by the originator or shall be allowed to be deducted from the first month’s collection after the cut off date as agreed to between parties.

Working out cut off date balances
The outstanding principal as on the cut-off date, may be worked out by adjusting the original loan amount to the extent of the principal component of the EMIs payable up to the cut-off date together with the adjustment for any prepayments received during this period. Any EMI/other charges remaining unpaid as on the cut off date shall be shown separately as the cut off date receivables.

Credit Enhancement
In order to maintain a AAA rating and to improve the performance of the pool as also to ensure uninterrupted cashflow for yielding the indicated coupon interest to the purchaser or subsequent investors in the MBS paper, the Rating Agency or NHB may insist for additional credit support (called credit enhancement) under the transaction. The credit enhancement may be provided in various forms such as setting aside a cash pool (called cash collateral account), limited corporate guarantee, third party guarantee, setting aside an additional mortgage pool (called over-collateralisation), investment in sub-ordinated MBS paper (in the event of securitisation) etc. In the event of securitisation of mortgage debt abinitio, credit support will be sought on the basis of recommendation of the credit rating agency.

Liquidity Adjustment Facility
In view of delayed receipt of instalments from some borrowers at times and grace periods allowed by the primary lending agencies to its borrowers, collection efficiencies may vary from month to month leading to inadequacy of cashflow required for servicing. In order to protect the purchaser of housing loans/investors in MBS from such uncertainties, there may be a need to set up a ‘Liquidity Adjustment Facility’ as a temporary stopgap arrangement. NHB may decide the size/quantum of such a facility and require the seller of housing loans to provide such a facility separately or in combination with the credit enhancement provided by them. NHB may also consider outsourcing such a facility at a cost to be borne by the seller or out of the pool cashflows depending on the structure of the arrangement.

Custody of Mortgage Documents
While the mortgage debt or the receivables pertaining to the MBS transaction will be legally transferred to NHB/SPV Trust, the originator (primary lending agency) will continue to physically hold the title documents in respect of the housing properties, obtained as security on the loans issued, in the capacity of a custodian to NHB/SPV Trust and deal with the same or all realisations therefrom only in accordance with the directions of NHB. Also, the originator shall , on being so advised by NHB, give notice to the Borrower/s and/or third parties and enforce the security/ies in its own name, if so required, for realisations of the outstanding due/s which is/are unpaid by the Borrowers and shall, when so advised by NHB in writing, transfer or deliver to the NHB all relative documents, records, contracts and writing and papers in respect of the housing loans and securities connected therewith.

Design of MBS Instruments
The mortgage debt will be purchased by NHB with a right to securitize them on the same/at a later date. However, irrespective of whether the proposal is for purchase of mortgage debt or for securitization of housing loans, NHB will be free to design and issue any kind of innovative instruments as it may deem fit.

Appointment of Various Agencies
In the event of securitization of mortgage debts by NHB, NHB may decide to get the MBS instrument(s) rated by one or more rating agencies, engage the services of one or more Issue Arrangers for preparation of the Memorandum of Information pertaining to the issue and placement of the issue on private placement or public issue basis, appoint the originator (Primary Lending Agency) or any other agency as the Servicing and Paying Agent under the transaction, engage the services of Registrar and Transfer Agent (in the event of securitization) and such other agencies as NHB may consider appropriate for smooth operation of the scheme.

NHB may consider getting the MBS instrument listed in one or more Stock Exchanges and dematerialized the same with any of the Depositories at its sole discretion.

Payment of Consideration
NHB will make payment of consideration for the purchase of mortgage debts (for holding it in its own book or for the purpose of securitization abinitio) after issue of allotment letters to investors or after execution of the legal documents relating to the transaction or on such date as mutually agreed to between the buyer and the seller.

Establishment of Special Purpose Vehicle for Issue of MBS
In the event of securitization of housing loans, NHB may set up one or more Special Purpose Vehicles (SPVs) in the form of Trust(s) or any other constitution for implementation of the scheme.

Post Issue Servicing and Reporting Requirements
The Servicing and Paying Agent appointed by NHB shall submit monthly reports in respect of collections in the transferred pool of mortgages and such other MIS Reports, Statement of Accounts and Trial Balances as prescribed by NHB from time to time. NHB or a firm of Chartered Accountants appointed by NHB in this behalf will have the right to carry out inspection and/or audit of the loan account to verify the correctness of the reports and statements.
