An NBFC securitisation under the RBI September 2021 Master Direction transfers a pool of standard assets to an SPV and issues PTCs to investors. The originator stays as servicer and must, every month, reconcile pool collections against the contractual cash-flow waterfall, prove True-Sale and Minimum Retention Requirement compliance, and deliver an audit and rating-agency evidence pack — all without breaking the senior-tranche payout window.
Capture pool-level collections daily and aggregate at month-end. Apply the cash-flow waterfall in trust-deed order — senior expenses, senior interest, senior principal, mezzanine, credit-enhancement replenishment, originator excess spread. Compute and verify MRR retention. Generate the trustee, investor, and rating-agency reports from the same data lineage.
SPV trust-deed parameter set — tranche definitions, waterfall order, credit-enhancement structure, MRR percentage, payout date. Pool master with seasoning, original tenor, and asset class. Trustee account mapping for remittance reconciliation.
Monthly trustee remittance file accepted on the payout date, waterfall sign-off pack, MRR retention proof, True-Sale confirmation log, and audit-ready evidence chain for statutory auditors and rating agencies.
Securitisation has been a structural funding tool for Indian NBFCs since the late 1990s. The RBI Master Direction on Securitisation of Standard Assets, issued in September 2021, consolidated and modernised the framework — replacing the 2012 guidelines, aligning with Basel norms, and introducing Simple, Transparent, and Comparable (STC) securitisations. For an originator NBFC, the reconciliation discipline at each monthly cutoff is what makes securitisation work in practice. The transaction’s economics depend on the senior payout never breaking; the regulatory standing depends on True-Sale being defensible at every audit; and the rating depends on a clean monthly performance pack.
Quick reference: the structure
| Element | Role | NBFC’s relationship |
|---|---|---|
| Originator | NBFC selling the pool | The NBFC itself |
| SPV (trust) | Holds the assets, issues PTCs | Bankruptcy-remote, trustee-controlled |
| Servicer | Collects from underlying borrowers | Usually the originator NBFC |
| Trustee | Administers the SPV, holds investor interest | Independent — bank or corporate trustee |
| Credit enhancer | Provides over-collateralisation, cash collateral, or guarantee | Originator within MRR plus separate limit |
| Investors | Hold senior, mezzanine, and equity PTCs | Banks, mutual funds, NBFCs, FPIs |
True-Sale: the legal foundation that audit re-verifies each cutoff
True-Sale is not a one-time event at issuance. It must hold at every reporting cutoff for the transaction to remain off the originator’s balance sheet. The Master Direction prescribes the substance test: irrevocable transfer, no residual control, credit enhancement capped within prescribed limits, and clean break from insolvency risk of the originator. Statutory auditors revisit this at each cutoff. A re-acquisition of an underlying asset by the originator outside the contracted clean-up call provisions — even for genuine operational reasons — risks collapsing True-Sale on the entire pool.
The originator must therefore maintain a register of every asset removed from or added to the pool, the reason, and the contractual basis. Reconciliation against the trustee’s pool register confirms there is no unexplained re-acquisition.
Minimum Retention Requirement
The MRR rules under the 2021 Master Direction differ by asset class and original tenor. Broadly, for pools with original maturity above 24 months, the retention is 10% of the book value of the loans being securitised. The retention can be held in three forms:
- An undivided share in each loan in the pool
- A first-loss position
- The most subordinated tranche of the PTC structure
Reconciliation tracks closing pool balance, the format of retention, and the percentage retained against the regulatory floor. The retention is bound — it cannot be hedged, transferred, or used as collateral for another transaction during the life of the pool.
The monthly servicer reconciliation in four steps
Every month, on the contractual cutoff (typically the last calendar day), the servicer NBFC runs:
- Pool-level collection summary — aggregating every collection event by loan account, instalment, and category from the loan-management system. Includes principal, interest, prepayments, and any recoveries on overdue accounts.
- Waterfall application — applying collections to payment heads in trust-deed order. Trustee and statutory expenses go first; then senior tranche interest and principal as per the schedule; then mezzanine; then credit-enhancement replenishment; then originator excess spread.
- Credit-enhancement utilisation log — tracking any drawdown on cash collateral, over-collateralisation, or first-loss layer in the month. Replenishment requirements roll into the next month’s waterfall.
- Sign-off pack — shared with trustee, rating agency, and statutory auditor. Trustee uses it to authorise remittance; rating agency uses it to refresh the rating; auditor uses it to verify True-Sale and MRR compliance.
Try the cash-flow application logic against a sample month using the TDS mismatch estimator framework adapted to payout waterfalls — the same matching discipline (open ledger → applied amount → residual carry) applies.
DPD bucket movement and roll-rate
Investors and rating agencies focus heavily on roll-rates: the percentage of the pool that moves from current to 30 DPD, from 30 DPD to 60 DPD, from 60 DPD to 90 DPD, and from 90 DPD into NPA. A rising roll-rate is the leading indicator of pool deterioration. The servicer must therefore produce, every month:
- Closing pool balance by DPD bucket
- Roll-rate matrix for the month and rolling three months
- Prepayment rate (CPR or SMM)
- Loss-given-default and recovery experience to date
These tie into the trustee report and become public for STC-compliant structures.
Tax overlay: TDS on PTC interest
Interest paid to PTC investors is subject to TDS under the applicable section based on the investor’s status. The SPV (acting through the trustee) deducts and remits TDS, files the quarterly return, and issues Form 16A. The originator-servicer often runs this on the SPV’s behalf under the master agreement. Reconciliation must tie:
- Monthly interest accrued to investors
- TDS deducted and challan-paid
- Quarterly TDS return filed by the SPV
- Form 16A issued to investors
A break here surfaces only at the investor’s ITR-filing stage, by which point the operating data is months old. Tight monthly discipline avoids the year-end fire drill.
Audit and rating-agency evidence at each cutoff
A defensible securitisation operation produces, at each monthly cutoff:
- Pool performance report (collections, prepayments, DPD movements, roll-rates)
- Waterfall computation tied to actual remittance
- Credit-enhancement utilisation and replenishment log
- MRR retention proof with form of holding
- True-Sale confirmation log
- TDS deduction and remittance summary for PTC interest
- Variance log for any unexplained gap
Producing this monthly pack across multiple outstanding SPVs is the operational scaling challenge most originator NBFCs hit by their fourth or fifth live transaction.
How TransactIG handles the SPV servicing surface
TransactIG configures each SPV as a parameter set — tranche structure, waterfall order, credit-enhancement parameters, MRR, payout dates, trustee account mapping. The engine ingests daily collections from the loan-management system, aggregates at cutoff, applies the waterfall, computes credit-enhancement movements, generates the trustee remittance and investor-payout files, and produces the monthly audit and rating-agency pack from the same data lineage. New SPVs onboard as new configuration — no code fork per transaction.
