Asset-Backed Security
An asset-backed security is a debt or beneficial-interest claim supported primarily by cash flows from a defined pool of financial assets.
Structured-credit concepts for tracing asset and bond pools through issuing vehicles, tranches, waterfalls, enhancement, servicing, and investor claims.
Structured-credit vehicles convert asset or contract cash flows into investor claims governed by legal transfer, servicing, enhancement, triggers, and payment priority. The transaction must be analyzed as a system: collateral performance alone does not determine which class receives cash or absorbs loss.
Asset-Backed Security follows cash flows from pooled receivables to investor securities. Collateralized Bond Obligation narrows that analysis to a bond-backed CDO and its senior, mezzanine, and first-loss tranches. Special Purpose Vehicle separates legal form, bankruptcy remoteness, recourse, and accounting consolidation. Structured Finance explains tranches, waterfalls, enhancement, and triggers.
| Layer | Main question |
|---|---|
| Collateral | Which loans, receivables, leases, contracts, or reference exposures generate risk and cash? |
| Transfer | Were assets validly transferred, perfected, and isolated under the intended structure? |
| Vehicle | What can the issuing entity own, owe, guarantee, or do? |
| Servicing | Who collects, advances, modifies, reports, and recovers cash? |
| Waterfall | Which fees and classes are paid first, and how does priority change after triggers? |
| Enhancement | Which subordination, reserves, excess spread, guarantees, or facilities absorb stress? |
| Investor claim | What are the tranche’s attachment point, maturity, average life, coupon, rights, and recourse? |

|---|---|
| Asset-Backed Security | Receivable and loan pools, servicing, enhancement, and tranche cash flows. |
| Collateralized Bond Obligation | Bond collateral, CDO capital structure, coverage tests, and loss allocation. |
| Special Purpose Vehicle | Legal entity, asset isolation, recourse, control, and consolidation questions. |
| Structured Investment Vehicle | Historical leveraged vehicles funded with short- and medium-term liabilities. |
Review normal and stressed waterfalls, not only headline collateral and rating. Verify sponsor, servicer, trustee, account bank, hedge and liquidity counterparties, legal opinions, consolidation disclosures, trigger cushions, and current investor reports.
A separate vehicle does not eliminate credit risk, guarantee sponsor support, or automatically produce off-balance-sheet treatment. A senior tranche can be protected from early losses while remaining exposed to severe collateral stress, extension, liquidity, model, legal, and counterparty risk.
Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.
An asset-backed security is a debt or beneficial-interest claim supported primarily by cash flows from a defined pool of financial assets.
A collateralized bond obligation is a CDO backed primarily by bonds and divided into senior, mezzanine, and first-loss tranches.
A special purpose vehicle is a legally distinct, limited-purpose entity used to hold assets, issue claims, or isolate a financing transaction.
Structured finance reshapes asset cash flows and risk through special-purpose entities, tranches, enhancement, triggers, and payment waterfalls.
A structured investment vehicle was a leveraged funding entity that invested in longer-term assets using shorter-term debt and subordinated capital.
