Definition of ABS (Asset-Backed Security)

What is an ABS?

An Asset-Backed Security (ABS) is a type of non-mortgage-backed security that is derived from and backed by a variety of financial assets, excluding real estate and mortgages.

Key Elements of ABS:

• Underlying Assets: Typically include loans, leases, credit card debt, or other receivables.
• Tranches: ABS are often divided into different classes known as tranches, each with varying risks and returns.
• Issuer: Usually, a Special Purpose Vehicle (SPV) is established to issue ABS and collect the income from the underlying assets.

Types of ABS

Common Types of Asset-Backed Securities

• Credit Card Receivables: Securities backed by pools of credit card debt handled by financial institutions.
• Auto Loans: Bonds collateralized by car loans.
• Student Loans: ABS collateralized by loans given to students.
• Equipment Leases: Securities backed by payments made for leasing equipment.
• Home Equity Loans: Loans taken with home equity as collateral, excluding primary mortgage loans.

Historical Context of ABS

Evolution

The ABS market began to flourish in the 1980s, following the development of Mortgage-Backed Securities (MBS). This trend gained traction as financial institutions sought diverse means of funding and risk management. The advent of ABS provided a way for banks to offload risk from their balance sheets while supplying investors with attractive returns.

Structure and Mechanism

Securitization Process

• Pooling of Assets: A financial institution pools various assets like loans or receivables.

2. Special Purpose Vehicle (SPV): An SPV is created to hold the pool of assets.

• Issuance of ABS: The SPV issues securities backed by these assets.
• Income Flow: Investors receive income from the amortization and interest payments of the underlying assets.

$$ \text{ABS\ Value} = \sum_{i=1}^{n} CF_i \cdot (1 + r)^{-i} $$

Where \( CF_i \) denotes the cash flows at time \( i \) and \( r \) is the discount rate.

Examples of Asset-Backed Securities

• Credit Card ABS: Securities backed by revolving credit card payments.
• Auto Loan ABS: Include bonds backed by car loans.
• Collateralized Debt Obligations (CDOs): Structured ABS backed by a diversified pool of debt instruments.

Applicability and Considerations

Risk and Return

• Credit Risk: The possibility of default by the borrowers of the underlying assets.
• Prepayment Risk: Risk that the underlying assets get prepaid, affecting the yield.
• Liquidity Risk: Risk associated with the ease of buying/selling the ABS in the market.

Regulations

ABS are subject to various regulations to ensure transparency and mitigate systemic risks, including comprehensive disclosure requirements.

Related Terms

• Mortgage-Backed Security (MBS): A type of ABS that is secured by a mortgage or collection of mortgages.
• Tranche: A piece or slice of a pool of securities, each with varying risk and return features.
• Special Purpose Vehicle (SPV): A subsidiary created by a parent company to isolate financial risk.
