A bank pools auto loans into a bankruptcy-remote trust that issues senior, mezzanine, and equity notes. That structure, and how it differs from a covered bond sitting on the issuer's balance sheet, is the heart of this reading, which goes on to describe the typical credit enhancement structures securitizations use, the main non-mortgage ABS types, and CDOs.
A covered bond is a debt security issued by a bank and backed by a segregated cover pool of mortgages or public-sector loans. Investors get dual recourse: a claim on the issuing bank AND on the pool. The assets stay on the bank's balance sheet.
In an ABS, the originator sells the pool to a special purpose entity (SPE) that is bankruptcy-remote. The SPE issues notes whose only recourse is the pool. If the originator fails, the SPE's assets are insulated.
KEY: Dual recourse + on-balance-sheet + dynamic pool = covered bond. Single recourse + off-balance-sheet SPE + static pool = ABS.
The cover pool is dynamic: defaulted or prepaid assets are replaced to maintain overcollateralization. ABS pools are static.
Common mistakes
- Treating covered bonds as ABS. Covered bonds stay on the issuer's balance sheet with dual recourse. ABS pools sit in a bankruptcy-remote SPE. Trap: assuming the SPE structure applies to covered bonds because "both are pool-backed."
- Mixing internal and external credit enhancement. Subordination, OC, excess spread, and reserve accounts are internal. Letters of credit, surety bonds, and third-party guarantees are external. Trap: classifying a reserve account funded from excess spread as external because cash sits aside.
- Forgetting the credit card lockout. During lockout, principal is reinvested and investors receive interest only. Trap: assuming a credit card ABS amortizes from day one like an auto-loan ABS.
Bottom line
- Covered bonds: dual recourse (issuer + cover pool), on-balance-sheet, dynamic pool, usually bullet. ABS: recourse to the SPE pool only, off-balance-sheet, static pool.
- ABS sits in a bankruptcy-remote SPE, insulating investors from originator failure. Covered bonds have no SPE because they stay on the issuer's balance sheet.
- Internal credit enhancement = tranching, overcollateralization, excess spread, reserve account. External = surety bond, letter of credit, third-party guarantee.
- External enhancement adds counterparty risk: monoline insurer downgrades cascade to every bond they wrap, as seen in 2008.
Exam shortcut
For covered bond vs. ABS: "Dual recourse plus dynamic pool = covered. Single recourse plus static SPE = ABS." For credit enhancement: internal is structural, external is third party (and brings counterparty risk). For non-mortgage ABS: amortizing (auto) versus revolving with lockout (credit card), with residual value risk added for leases. For CDOs: senior pays first and loses last; equity is the residual claim and the arbitrage earner.
