Learning Module 17 Fixed-Income Securitization
50 questions available
Securitization delivers benefits: for issuers, off-balance-sheet funding, capital efficiency, fee income, and expanded lending capacity; for investors, tailored risk/return and maturity choices and enhanced liquidity; for markets and economies, improved liquidity, diversified funding channels, and capital allocation efficiency. Examples include whole-business securitizations, solar ABS, auto ABS, and corporate receivable securitizations.
Key Points
- Securitization transfers assets to an SPE that issues ABS to investors.
- SPEs aim to be bankruptcy-remote so investor cash flows depend on collateral.
- Covered bonds keep assets on the issuer balance sheet and provide dual recourse.
- Benefits accrue to issuers (capital efficiency), investors (tailored risk), and markets (liquidity).
Credit enhancement reduces expected loss to investors. Internal enhancements include subordination/credit tranching (waterfall), overcollateralization (collateral larger than issued debt), and excess spread (margin between collateral coupon and security coupon). External enhancements include guarantees, letters of credit, and cash collateral accounts. These mechanisms determine ratings and investor remuneration. Tranching redistributes both credit and prepayment risk: junior tranches absorb first losses; senior tranches have lower LGD exposure and often higher ratings.
Key Points
- Pass-through versus tranched ABS (senior/subordinated) allocate cash by priority.
- Internal credit enhancements: subordination, overcollateralization, excess spread.
- External enhancements: guarantees, LOCs, cash accounts.
- MBS, CMOs, and non-mortgage ABS differ by collateral and payment mechanics.
Key Points
- Prepayment risk has contraction (shortening) and extension (lengthening) components.
- Time tranching creates tranches with different expected maturities to reallocate prepayment risk.
- PACs and support tranches stabilize cash flows; Z-tranches defer interest.
- PO and IO securities isolate principal or interest cash flows and react differently to prepayments.
Commercial mortgage-backed securities (CMBS) are backed by income-producing property loans. CMBS often include call protection at the structural or loan level through lockouts, prepayment penalties, or defeasance and are more like corporate bonds in behavior. Many commercial loans are balloon loans, creating balloon risk (a form of extension risk) if borrowers cannot refinance or repay at maturity. CMBS pools tend to be concentrated; therefore, single-loan defaults can significantly affect investors. Key credit metrics include LTV and DSCR (NOI divided by debt service).
Key Points
- Covered bonds provide dual recourse and keep collateral on issuer balance sheet.
- CMBS provide call protection and often feature balloon payments, raising extension/balloon risk.
- CMBS pools can be concentrated, so investors must analyze individual loans and properties.
- DSCR and LTV are critical for CMBS credit assessment.
Key Points
- CDOs/CLOs redistribute diversified debt cash flows into tranches; CLOs are actively managed.
- Collateral managers and covenant triggers affect cash allocation and deleveraging.
- True-sale legal effectiveness and bankruptcy remoteness differ across jurisdictions.
- Real-world examples highlight market, structural, and issuer-specific risks.
