Parties and Structure of a Securitization Transaction

Updated 11 October 2026 · Fact-checked

Securitization turns illiquid loans into tradable securities. The originator sells a pool of receivables to a special purpose vehicle (SPV). The SPV issues securities to investors and pays them from the pool's collections. A servicer collects dues, a trustee protects investors, and a rating agency rates the securities.

Understand Parties and Structure of a Securitization Transaction

Start with the problem. A bank or NBFC has lent money for years, such as home loans or vehicle loans. The cash is locked up until borrowers repay. If the lender wants cash now, it can sell those loans. Securitization is a structured way to do this.

The lender is the originator. It picks a group of similar loans, called the pool, and sells it to a special purpose vehicle (SPV). The SPV is a separate legal entity, often a trust or company, set up only to hold the pool and issue securities. This is called a true sale: the assets leave the originator's balance sheet. So if the originator fails later, its creditors cannot claim the pool. This is called bankruptcy remoteness and it is the main reason the SPV exists.

The SPV pays for the pool by issuing securities to investors. Investors are usually banks, mutual funds, insurers and other institutions. The obligors are the original borrowers. Their EMIs are the cash flow that pays investors. The obligors usually do not even know the loan was sold, as they keep paying as before.

Several helpers make the structure work. The servicer collects EMIs, chases defaults, and passes the money to the SPV or trustee. Often the originator itself acts as servicer. The trustee holds the pool for investors and watches that everyone follows the deal documents. A credit rating agency rates the securities based on pool quality and credit enhancement. Other parties can include a lead arranger, who structures the deal, and a credit enhancer or liquidity provider.

Securities come in two broad forms. In pass through securities, the SPV passes collections, both interest and principal, straight to investors in proportion to their holdings. Investors own an undivided share of the pool and bear its prepayment risk. In pay through securities, the SPV issues debt-like securities, often in tranches with different maturities and priorities. Collections are reinvested or rearranged, and payments follow the set terms, not just the collections of that period.

Key rules to remember

Flow of the structure: Obligors → Servicer → SPV / Trustee → Investors; Cash flows upward from borrowers to investors. The sale flows the other way: Originator → SPV (pool), SPV → Investors (securities).
SPV purchase price: Price paid by SPV = Present value of pool cash flows at investors' required yield; Originator receives this in cash. It is also the amount the SPV raises from investors, less any issue expenses.
Pass through payout: Investor payment = Collections (interest + principal) − servicing fee, shared pro rata; Pass through payment depends on actual collections. If the pool pays slower or faster, investors receive accordingly.
Excess spread: Excess spread = Pool interest rate − (Investor coupon + Servicer fee); A common first line of credit cushion. State it as a rate per year on the outstanding pool.

How to solve Parties and Structure of a Securitization Transaction questions

Use this order for any question that asks you to describe, explain or compute in a securitization structure.

1Identify the originator and what asset pool it is selling (loan type, size, tenure).
2Name the SPV and state why it exists: true sale, bankruptcy remoteness, separate legal entity.
3Identify the obligors and say that their repayments are the source of cash for investors.
4Assign roles: servicer collects, trustee protects investors, rating agency assesses credit quality, arranger structures the deal.
5Decide the security type: pass through (direct share of collections) or pay through (structured, often tranched, debt-like).
6For numerical parts, find the pool cash flows, subtract servicing fee, and discount at the investors' yield to get the SPV price.
7Close with a short conclusion: who gets cash, who bears risk, and what protects investors.

Quickest way: Role-flow-risk scan

When to use it: Use this for short-answer or MCQ questions that ask 'who does what' in a securitization.

Ask first: who is selling and who is buying? Originator sells, SPV buys.
Ask: who pays the cash? Obligors, through the servicer.
Ask: who checks and protects? Trustee and rating agency.
Match the security: if investors get collections directly, it is pass through; if the SPV restructures payments, it is pay through.
Eliminate options that make the SPV a part of the originator's balance sheet or let the originator keep control of the pool.

Common mistakes in Parties and Structure of a Securitization Transaction

Calling the borrower the originator.
Both words sound like the start of the loan.
Fix: The originator is the lender that sells the assets. The borrower is the obligor.
Saying the SPV exists only to reduce tax.
Students link SPVs with tax planning in general.
Fix: The core purpose is a true sale and bankruptcy remoteness, so investors depend on the pool and not the originator's solvency.
Mixing up servicer and trustee.
Both look like administrative roles.
Fix: Servicer collects and remits cash. Trustee holds the pool for investors and supervises compliance. Remember: servicer works with money, trustee works for investors.
Treating pass through and pay through as the same.
Both pay investors from pool collections.
Fix: Pass through gives investors a proportionate share of actual collections, including prepayments. Pay through issues structured securities with set terms, often in tranches.
Saying obligors must be told and must pay a new party.
Students assume a sale of a loan always changes the payee.
Fix: Usually the originator continues as servicer, so borrowers keep paying it. It then remits to the SPV.
Forgetting the originator's benefit in the answer.
Focus stays on mechanics.
Fix: State the gains: immediate cash, better liquidity, assets off the balance sheet, and capital relief where applicable.

Worked examples

Example 1

A bank sells a pool of auto loans to an SPV. The SPV issues securities to investors. The bank continues to collect EMIs from borrowers. Name each party and explain how cash and risk flow.

Show the solution

Originator: the bank, which sold the auto loans for cash.
SPV: the entity that bought the pool and issued securities. It is legally separate, so the pool is isolated from the bank's insolvency.
Obligors: the auto loan borrowers, whose EMIs generate the cash flow.
Servicer: the bank, as it collects EMIs and passes them to the SPV or trustee, usually for a fee.
Investors: buyers of the securities. They receive payments from pool collections and bear the pool's credit risk, up to any credit enhancement.
Cash flow: borrowers → bank as servicer → SPV or trustee → investors. Sale price flows from SPV to the bank at the start.

Answer: The bank is originator and servicer, the SPV holds the pool and issues securities, borrowers are obligors, and investors are paid from pool collections. The true sale separates the pool from the bank's own risk.

Example 2

An SPV buys a pool of receivables that will pay ₹1,10,000 at the end of one year. Investors require a yield of 10% per year. Find the price the SPV can pay the originator, ignoring costs. Also state the pool's effect on the originator's balance sheet.

Show the solution

The pool's only cash flow is ₹1,10,000 after one year.
Price = PV at 10% = 1,10,000 ÷ 1.10.
1,10,000 ÷ 1.10 = ₹1,00,000.
As the sale is a true sale, the originator removes the receivables from its books and records ₹1,00,000 cash.
Investors earn ₹10,000 on ₹1,00,000, which is the 10% yield.

Answer: The SPV can pay ₹1,00,000. The receivables leave the originator's balance sheet and are replaced by cash of ₹1,00,000.

Exam tips

Draw a small flow diagram of the parties in descriptive answers. It scores fast and shows structure.
Always say why the SPV is separate: true sale and bankruptcy remoteness. Examiners look for this phrase or its meaning.
When asked to compare pass through and pay through, use two or three points: investor's claim, prepayment risk, and structure of payments.
In case-based MCQs, find who performs each action in the scenario and match it to a role before reading the options.
For numerical questions, show discounting at the investors' yield and then state the effect on the originator in one line.

Parties and Structure of a Securitization Transaction: frequently asked questions

What is the role of an SPV in securitization?

The SPV buys the pool of assets from the originator and issues securities to investors. It is a separate legal entity, so the pool is protected if the originator becomes insolvent. Its only business is holding the pool and paying investors.

Who is the servicer in a securitization transaction?

The servicer collects payments from obligors, follows up on defaults and remits the money to the SPV or trustee. The originator often acts as servicer and earns a fee for it.

What is the difference between pass through and pay through securities?

In pass through securities, investors get a pro rata share of the actual collections, so prepayments and delays affect them directly. In pay through securities, the SPV issues debt-like securities with set terms, often in tranches, and payments follow those terms.

Why is a rating agency needed in the structure?

Investors cannot easily assess a pool of loans on their own. The rating agency studies the pool quality and credit enhancement and gives a rating that guides pricing and investor demand.
