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.
The Government National Mortgage Association (GNMA), or Ginnie Mae, is a government-owned corporation of the United States Federal Government within the Department of Housing and Urban Development (HUD). It was founded in 1968 and works to expand affordable housing by guaranteeing housing loans (mortgages) thereby lowering financing costs such as interest rates for those loans. It does that through guaranteeing to investors the on-time payment of mortgage-backed securities (MBS) even if homeowners default on the underlying mortgages and the homes are foreclosed upon.
A repurchase agreement, also known as a repo, RP, or sale and repurchase agreement, is a form of short-term borrowing, mainly in government securities. The dealer sells the underlying security to investors and, by agreement between the two parties, buys them back shortly afterwards, usually the following day, at a slightly higher price.
Fixed income refers to any type of investment under which the borrower or issuer is obliged to make payments of a fixed amount on a fixed schedule. For example, the borrower may have to pay interest at a fixed rate once a year and repay the principal amount on maturity. Fixed-income securities — more commonly known as bonds — can be contrasted with equity securities – often referred to as stocks and shares – that create no obligation to pay dividends or any other form of income. Bonds carry a level of legal protections for investors that equity securities do not — in the event of a bankruptcy, bond holders would be repaid after liquidation of assets, whereas shareholders with stock often receive nothing.
An interest-only loan is a loan in which the borrower pays only the interest for some or all of the term, with the principal balance unchanged during the interest-only period. At the end of the interest-only term the borrower must renegotiate another interest-only mortgage, pay the principal, or, if previously agreed, convert the loan to a principal-and-interest payment (amortizing) loan at the borrower's option.
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.
Hypothec, sometimes tacit hypothec, is a term used in civil law systems or mixed legal systems to refer to a registered non-possessory real security over real estate, but under some jurisdictions it may sometimes also denote security on other collaterals such as securities, intellectual property rights or corporeal movable property, either ships only as opposed to other movables covered by a different type of right (pledge) in the legal systems of some countries, or any movables in legal systems of other countries. The common law has two equivalents to the term, namely mortgage and non-possessory lien.
A government-sponsored enterprise (GSE) is a type of financial services corporation created by the United States Congress. Their intended function is to enhance the flow of credit to targeted sectors of the economy, to make those segments of the capital market more efficient and transparent, and to reduce the risk to investors and other suppliers of capital. The desired effect of the GSEs is to enhance the availability and reduce the cost of credit to the targeted borrowing sectors primarily by reducing the risk of capital losses to investors: agriculture, home finance and education. Well known GSEs are the Federal National Mortgage Association, known as Fannie Mae, and the Federal Home Loan Mortgage Corporation, or Freddie Mac.
Fixed-income arbitrage is a group of market-neutral-investment strategies that are designed to take advantage of differences in interest rates between varying fixed-income securities or contracts. Arbitrage in terms of investment strategy, involves buying securities on one market for immediate resale on another market in order to profit from a price discrepancy.
Prepayment is the early repayment of a loan by a borrower, in part or in full, often as a result of optional refinancing to take advantage of lower interest rates.
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.
In finance, securities lending or stock lending refers to the lending of securities by one party to another.
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.
In finance, subprime lending is the provision of loans to people in the United States who may have difficulty maintaining the repayment schedule. Historically, subprime borrowers were defined as having FICO scores below 600, although this threshold has varied over time.
An Alt-A mortgage, short for Alternative A-paper, is a type of U.S. mortgage that, for various reasons, is considered riskier than A-paper, or "prime", and less risky than "subprime," the riskiest category. For these reasons, as well as in some cases their size, Alt-A loans are not eligible for purchase by Fannie Mae or Freddie Mac. Alt-A interest rates, which are determined by credit risk, therefore tend to be between those of prime and subprime home loans, although there is no single accepted definition of Alt-A. Typically Alt-A mortgages are characterized by borrowers with less than full documentation, average credit scores, higher loan-to-values, and more investment properties and secondary homes. A-minus is related to Alt-A, with some lenders categorizing them the same, but A-minus is traditionally defined as mortgage borrowers with a FICO score of below 680 while Alt-A is traditionally defined as loans lacking full documentation. Alt-A mortgages may have excellent credit but may not meet underwriting criteria for other reasons. During the past decade, a significant amount of Alt-A mortgages resulted from refinancings, rather than property purchases.
Bonds securitizing mortgages are usually treated as a separate class, termed residential mortgage-backed security (RMBS). In that sense, making reference to the general package of financial agreements that typically represents cash yields that are paid to investors and that are supported by cash payments received from homeowners who pay interest and principal according to terms agreed to with their lenders; it is a funding instrument created by the "originator" or "sponsor" of the mortgage loan; without cross-collateralizing individual loans and mortgages, it is a funding instrument that pools the cash flow received from individuals and pays these cash receipts out with waterfall priorities that enable investors to become comfortable with the certainty of receipt of cash at any point in time.
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.
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).
