Agency Pass-Throughs

Introduction

We will look into the realm of pass-through securities in this tutorial. These financial instruments, such as mortgage- and asset-backed securities, give investors access to the cash flows from a collection of underlying assets. We have talked about aspects of them including pro-rata distribution, asset pooling, and cash flow pass-through. We will also emphasize the dangers, such as prepayment, interest rate, credit, and liquidity dangers. Investors considering including pass-through securities in their investment strategy must fully comprehend these factors. Let us explore the world of pass-through securities, including characteristics, risks, and benefits for investors.

Defining Pass Through Securities

A group of underlying assets, such as mortgages or other loans, can pool their cash flows through the use of investment vehicles called pass-through securities. The investors get periodic payments, usually interest and principal, in the form of the cash flows generated from the underlying assets.

Mortgage-backed securities (MBS) and Asset-Backed Securities (ABS) are two examples of pass-through securities. Pass-through security holders share in the cash flows based on the amount they invested in the security.

How Pass-through Securities Work?

By combining the cash flows from a number of underlying assets, such as mortgages or loans, pass-through securities function. The investors in the securities are given the cash flows, which include principal and interest payments. Based on their investment in the pass-through security, investors receive a portion of the cash flows. The profitability of the underlying assets and the borrowers' repayment habits both influence the payments investors get.

How Pass-through Certificates Work? – Explained with example

A pass-through certificate is a kind of security that shows ownership in a collection of assets, like loans or mortgages. The certificate holders get interest and principal payments from the cash flows produced by the underlying assets. According to their ownership percentage, the holders of the certificates receive a portion of the revenue and principal repayments. These certificates, which are frequently issued by special purpose entities, give investors exposure to the cash flows of the underlying assets, enabling diversification and income production.

A special purpose vehicle (SPV), such as a pool of underlying assets like mortgages or loans, is how pass-through certificates operate. Investors who purchase certificates from the SPV signify their ownership stake in the underlying assets. The cash flows are gathered by the SPV as borrowers pay interest and principal on the assets. The SPV then distributes these cash flows to the certificate holders according to their ownership stake in a pro rata manner. Based on how well the underlying assets perform, the certificate holders get regular payments, usually in the form of interest and principal. Investors can gain from the revenue and repayment streams of the underlying assets thanks to the pass-through structure.

Characteristics of Pass Through Securities

• Cash flow pass-through − Pass-through securities pay interest and capital to investors in exchange for the cash flows produced by the underlying assets.

• Asset pooling − Pass-through securities combine several underlying assets, including loans or mortgages, to produce a diversified investment portfolio.

• Pro-rata distribution − Cash flows are allocated to investors according to their ownership stake in the pass-through securities on a pro-rata basis.

• Reliance on performance of underlying assets − Investors' cash flows are directly impacted by the efficiency and repayment habits of the underlying assets.

• Distributed by vehicles with special purposes − Special purpose vehicles, which are distinct legal entities established to keep and manage the underlying assets, frequently issue pass-through securities

Risks Involved in Pass Through Securities

Pass-through securities carry certain risks that investors should consider −

• Prepayment risk − If borrowers opt to pay off their debts ahead of schedule, it will affect the cash flows that investors might expect.

• Interest rate risk − Because interest rates have an impact on borrowers' decisions, they can change the value of pass-through assets, especially mortgage-backed securities.

• Credit risk − The performance of the assets and the likelihood of receiving full repayment can both be impacted by the creditworthiness of the underlying borrowers.

• Liquidity risk − It may be difficult to buy or sell pass-through assets at desired prices due to the secondary market's possible lack of liquidity.

• Market risk − The performance and pricing of pass-through securities can be impacted by general market conditions, macroeconomic factors, and regulatory changes.

• Extension risk − Borrowers may be less reluctant to refinance in an environment with dropping interest rates, thus extending the investment's lifespan.

Investors should carefully assess these risks before investing in pass-through securities.

Examples of Pass Through Securities

Mortgage-backed securities (MBS) and asset-backed securities (ABS) are two examples of pass-through securities. MBS are a collection of residential mortgages that pass on to investors the cash flows from mortgage payments. Contrarily, ABS include a range of assets like auto loans, credit card receivables, or student loans.

Investors receive a share of a pooled cash flow from these underlying assets. Collateralized debt obligations (CDOs) and collateralized mortgage obligations (CMOs), which also use a pass-through structure, are more instances.

Conclusion

Pass-through securities, such as mortgage- and asset-backed securities, give investors exposure to a pool of the cash flows from the underlying assets. Based on how well the underlying assets perform, the certificate holders get regular payments, usually in the form of interest and principal. Investors can gain from the revenue and repayment streams of the underlying assets thanks to the pass-through structure.

Cash flows are allocated to investors according to their ownership stake in the pass-through securities on a pro-rata basis. Special purpose vehicles, which are distinct legal entities established to keep and manage the underlying assets, frequently issue pass-through securities.
