In structured finance, a tranche is one of a number of related securities offered as part of the same transaction. In the financial sense of the word, each bond is a different slice of the deal's risk. Transaction documentation (see indenture) usually defines the tranches as different "classes" of notes, each identified by letter (e.g., the Class A, Class B, Class C securities) with different bond credit ratings.
The word tranche means a division or portion of a pool or whole [1] and is derived from the French for 'slice', 'section', 'series', or 'portion', and is also a cognate of the English 'trench' ('ditch').
The term tranche is used in fields of finance other than structured finance (such as in straight lending, where multi-tranche loans are commonplace), but the term's use in structured finance may be singled out as particularly important. Use of "tranche" as a verb is limited almost exclusively to this field.
All the tranches together make up what is referred to as the deal's capital structure or liability structure. They are generally paid sequentially from the most senior to most subordinate (and generally unsecured), although certain tranches with the same security may be paid pari passu . The more senior rated tranches generally have higher bond credit ratings (ratings) than the lower rated tranches. For example, senior tranches may be rated AAA, AA or A, while a junior, unsecured tranche may be rated BB. However, ratings can fluctuate after the debt is issued, and even senior tranches could be rated below investment grade (less than BBB). The deal's indenture (its governing legal document) usually details the payment of the tranches in a section often referred to as the waterfall (because the monies flow down).
Tranches with a first lien on the assets of the asset pool are referred to as senior tranches and are generally safer investments. Typical investors of these types of securities tend to be conduits, insurance companies, pension funds and other risk averse investors.
Tranches with either a second lien or no lien are often referred to as "junior notes". These are more risky investments because they are not secured by specific assets. The natural buyers of these securities tend to be hedge funds and other investors seeking higher risk/return profiles.
"Market information also suggests that the more junior tranches of structured products are often bought by specialist credit investors, while the senior tranches appear to be more attractive for a broader, less specialised investor community". [2] Here is a simplified example to demonstrate the principle:
Tranching offers the following benefits:
Tranching poses the following risks:
The cardinal principle in the mortgage crisis is a very old one. You are almost always better off restructuring a loan in a crisis with a borrower than going to a foreclosure. In the past that was never at issue because the loan was always in the hands of someone acting as a fiduciary. The bank, or someone like a bank owned them, and they always exercised their best judgement and their interest. The problem now with the size of securitization and so many loans are not in the hands of a portfolio lender but in a security where structurally nobody is acting as the fiduciary.
In finance, a derivative is a contract that derives its value from the performance of an underlying entity. This underlying entity can be an asset, index, or interest rate, and is often simply called the underlying. Derivatives can be used for a number of purposes, including insuring against price movements (hedging), increasing exposure to price movements for speculation, or getting access to otherwise hard-to-trade assets or markets.
In finance, a high-yield bond is a bond that is rated below investment grade by credit rating agencies. These bonds have a higher risk of default or other adverse credit events but offer higher yields than investment-grade bonds in order to compensate for the increased risk.
A credit rating agency is a company that assigns credit ratings, which rate a debtor's ability to pay back debt by making timely principal and interest payments and the likelihood of default. An agency may rate the creditworthiness of issuers of debt obligations, of debt instruments, and in some cases, of the servicers of the underlying debt, but not of individual consumers.
In finance, a credit derivative refers to any one of "various instruments and techniques designed to separate and then transfer the credit risk" or the risk of an event of default of a corporate or sovereign borrower, transferring it to an entity other than the lender or debtholder.
A collateralized mortgage obligation (CMO) is a type of complex debt security that repackages and directs the payments of principal and interest from a collateral pool to different types and maturities of securities, thereby meeting investor needs.
A mortgage-backed security (MBS) is a type of asset-backed security which is secured by a mortgage or collection of mortgages. The mortgages are aggregated and sold to a group of individuals that securitizes, or packages, the loans together into a security that investors can buy. Bonds securitizing mortgages are usually treated as a separate class, termed residential; another class is commercial, depending on whether the underlying asset is mortgages owned by borrowers or assets for commercial purposes ranging from office space to multi-dwelling buildings.
Structured finance is a sector of finance — specifically financial law — that manages leverage and risk. Strategies may involve legal and corporate restructuring, off balance sheet accounting, or the use of financial instruments.
A collateralized debt obligation (CDO) is a type of structured asset-backed security (ABS). Originally developed as instruments for the corporate debt markets, after 2002 CDOs became vehicles for refinancing mortgage-backed securities (MBS). Like other private label securities backed by assets, a CDO can be thought of as a promise to pay investors in a prescribed sequence, based on the cash flow the CDO collects from the pool of bonds or other assets it owns. Distinctively, CDO credit risk is typically assessed based on a probability of default (PD) derived from ratings on those bonds or assets.
A syndicated loan is one that is provided by a group of lenders and is structured, arranged, and administered by one or several commercial banks or investment banks known as lead arrangers.
An asset-backed security (ABS) is a security whose income payments, and hence value, are derived from and collateralized by a specified pool of underlying assets.
Commercial mortgage-backed securities (CMBS) are a type of mortgage-backed security backed by commercial and multifamily mortgages rather than residential real estate. CMBS tend to be more complex and volatile than residential mortgage-backed securities due to the unique nature of the underlying property assets.
A real estate mortgage investment conduit (REMIC) is "an entity that holds a fixed pool of mortgages and issues multiple classes of interests in itself to investors" under U.S. Federal income tax law and is "treated like a partnership for Federal income tax purposes with its income passed through to its interest holders". REMICs are used for the pooling of mortgage loans and issuance of mortgage-backed securities and have been a key contributor to the success of the mortgage-backed securities market over the past several decades.
Single-tranche CDO or bespoke CDO is an extension of full capital structure synthetic CDO deals, which are a form of collateralized debt obligation. These are bespoke transactions where the bank and the investor work closely to achieve a specific target.
A structured investment vehicle (SIV) is a non-bank financial institution established to earn a credit spread between the longer-term assets held in its portfolio and the shorter-term liabilities it issues. They are simple credit spread lenders, frequently "lending" by investing in securitizations, but also by investing in corporate bonds and funding by issuing commercial paper and medium term notes, which were usually rated AAA until the onset of the financial crisis. They did not expose themselves to either interest rate or currency risk and typically held asset to maturity. SIVs differ from asset-backed securities and collateralized debt obligations in that they are permanently capitalized and have an active management team.
Credit enhancement is the improvement of the credit profile of a structured financial transaction or the methods used to improve the credit profiles of such products or transactions. It is a key part of the securitization transaction in structured finance, and is important for credit rating agencies when rating a securitization.
Collateralized loan obligations (CLOs) are a form of securitization where payments from multiple middle sized and large business loans are pooled together and passed on to different classes of owners in various tranches. A CLO is a type of collateralized debt obligation, or CDO.
A synthetic CDO is a variation of a CDO that generally uses credit default swaps and other derivatives to obtain its investment goals. As such, it is a complex derivative financial security sometimes described as a bet on the performance of other mortgage products, rather than a real mortgage security. The value and payment stream of a synthetic CDO is derived not from cash assets, like mortgages or credit card payments – as in the case of a regular or "cash" CDO—but from premiums paying for credit default swap "insurance" on the possibility of default of some defined set of "reference" securities—based on cash assets. The insurance-buying "counterparties" may own the "reference" securities and be managing the risk of their default, or may be speculators who've calculated that the securities will default.
Credit rating agencies and the subprime crisis is the impact of credit rating agencies (CRAs) in the American subprime mortgage crisis of 2007–2008 that led to the financial crisis of 2007–2008.
A renewable energy derivative is based on a new method of securitization, which is a structured finance process that pools and repackages cash-flow-producing financial assets into securities which are then sold to investors. The term "securitization" is derived from the fact that securities are used to obtain funds from investors.
Securitization is the financial practice of pooling various types of contractual debt such as residential mortgages, commercial mortgages, auto loans or credit card debt obligations and selling their related cash flows to third party investors as securities, which may be described as bonds, pass-through securities, or collateralized debt obligations (CDOs). Investors are repaid from the principal and interest cash flows collected from the underlying debt and redistributed through the capital structure of the new financing. Securities backed by mortgage receivables are called mortgage-backed securities (MBS), while those backed by other types of receivables are asset-backed securities (ABS).
