The uses that are made of securities have changed over time, both for the issuer and for the holder. Though the purpose of capital raising has sometimes been taken to be a defining characteristic of securities, its uses have expanded greatly in modern times.
They are often represented by a certificate. They include shares of corporate stock or mutual funds, bonds issued by corporations or governmental agencies, stock options or other options, other derivative securities, limited partnership units, and various other formal "investment instruments." Banknotes, checks, and some bills of exchange do not fall into this category. Commodities like Oil, Food grains can also be referred to as Securities. One can enter into contracts to buy or sell various quantities of such commodity securities in various commodity exchanges.
Concept of "security"Originally the term "securities" was used to denote security interests (such as mortgages and charges) supporting the payment of a debt or other obligation. In Early modern Europe, companies and government agencies began to raise capital from the public using secured debt oligations, which came to be known as "securities". As shares became more readily transferrable from the Victorian era, their functional similarity to debt securities became clearer, and both forms of investment became known as "securities". More recently, the term has also been extended to include units in investment funds and other forms of readily transferrable investment.
The concept of "securities" should be distinguished from "interest in securities". The latter are the assets of a client from whom an intemediary holds securities on an unallocated basis, commingled with the interests in securities of other clients. The distinction between securities and interests in securities is often overlooked in practice, although it is a source of legal risk.
Uses of securities
For the issuer
Issuers of securities include commercial companies, government agencies, local authorities and international and supranational organisations (such as the World Bank). Debt securities issued by government (called sovereign debt) generally carries a lower interest rate than corporate debt issued by commercial companies. Repackaged securities are usually issued by a company established for the purpose of the repackaging - called a special purpose vehicle (SPV).
New capital: Commercial enterprises have traditionally used securities as a means of raising new capital. Securities are an attractive option relative to bank loans, which tend to be relatively expensive and short term. Another disadvantage of bank loans as a source of financing is that the bank may seek a measure of control over the business of the borrower via financial covenants. Through securities, capital is provided by investors who purchase the securities. In a similar way, government will raise capital from securities (see government debt) if taxation and other income are insufficient to meet public expenditure. This will result in a budget deficit.
Repackaging: In recent decades securities have been issued to repackage existing assets. In a traditional securitisation, a financial institution may wish to remove assets from its balance sheet in order to achieve regulatory capital efficiencies or to accelerate its receipt of cash flow from the original assets. Alternatively, an intermediary may wish to make a profit by acquiring financial assets and repackaging them in a way which makes them more attractive to investors.
For the holder
Investors in securities may be retail, i.e. members of the public investing other than by way of business. The greatest part in terms of volume of investment is wholesale, i.e. by financial institutions acting on their own account, or on behalf of clients. Important institutional investors include investment banks, insurance companies, pension funds and other managed funds.
Investment: The traditional economic function of the purchase of securities is investment, with the view to receiving income and/or achieving capital gain. Debt securities generally offer a higher rate of interest than bank deposits, and equities may offer the prospect of capital growth. Equity investment may also offer control of the business of the issuer.
Collateral: The last decade has seen an enormous growth in the use of securities as collateral. Where A is owed a debt or other obligation by B, A may require B to deliver property rights in securities to A. These property rights enable A to satisfy its claims in the event that B becomes insolvent. Collateral arranagments are divided into two broad categories, namely security interests and outright collateral transfers. Commonly, commercial banks, investment banks and government agencies are significant collateral takers.
Types of securities
Securities are traditionally divided into debt securities and equities.
The holder of a debt security is owed a debt by the issuer and is entitled to the payment of principal and interest, together with other personal rights under the terms of the issue, such as the right to receive certain information. Debt securities are generally issued for a fixed term and redeemable by the issuer at the end of that term.
Treasury bonds are medium or long term debt securities issued by sovereign governments or their agencies. Typically they carry a lower rate of interest than corporate bonds. In addition to serving as a source of finance for governments, treasuries are used to manage the money supply in the money market operations of central banks.
Money market instruments are short term debt instruments, such as certificates of deposit, commercial paper and certain bills of exchange. They are highly liquid and are sometimes referred to as "near cash".
Eurosecurities are securities issued internationally outside their domestic market. They include eurobonds and euronotes. Eurobonds are characterically underwritten, and not secured, and interest is paid gross. A euronote may take the form of euro-commercial paper (ECP) or euro-certificates of deposit.
- Mortgage Backed Securities
An equity is an ordinary share in a company. The holder of an equity is a shareholder, owning a share, or fractional part of the issuer.
Hybrid securities combine some of the characteristics of both debt and equity securities.
Preference shares form an intermediate class of security between equities and debt. If the issuer is liquidated, they carry the right to receive interest and/or a return of capital in priority to ordinary shareholders.
Convertibles are bonds which can be converted, at the election of the bondholder, into another sort of security such as equities.
Equity warrants are contractual entitlements to purchase shares on pre-determined terms. They are often issued together with bonds or existing equities, but are detachable from them and separately tradeable.
Primary and secondary markets
The securities markets can be divided into the primary markets and the secondary markets. Primary markets (also known as capital markets) comprise of new securities to their first holders. The issue of new securities is commonly known as an Initial Public Offering (IPO). Issuers usually retain investment banks to assist them in finding buyers for these issues, and in many cases, to buy any remaining interests themselves. This arrangement is known as underwriting. In recent years the business of managing or underwriting issues of securities has been concentrated in the hands of a small number of investment banks, the most prominent of which are Goldman Sachs, Morgan Stanley and Merrill Lynch. The International Primary Markets Association (IPMA) is the trade association of banks and other investment institutions who are active in the primary markets.
Transferrability is an essential characteristic of securities. This trading is called the aftermarket or secondary market. Secondary markets often consist of what is called an exchange to facilitate the meeting of buyers and sellers. They are often referred to as stock exchanges, even though there are exchanges such as the Chicago Board of Options Exchange, where no stocks are traded. The International Securities Market Association (ISMA) is the trade association for the banks and other investment institutions that are active in the secondary markets.
Public offers and private placements
In the primary markets, securities may be offered to the public in a public offer. Alternatively, they may be offered privately to a limited number of persons in a private placement. Often a combination of the two is used. The distinction between the two is important to securities regulation and company law.
Another category, sovereign debt, is generally sold by auction to a specialised class of dealers.
Listing and OTC dealing
Securities are often listed in a stock exchange, an organised and officially recognised market on which securities can be bought and sold. Issuers may seek listings for their securities in order to attract investors, by ensuring that there is a liquid and regulated market in which investors will be able to buy and sell securities.
Growth in informal electronic trading systems has challenged the traditional business of stock exchanges. Large volumes of securities are also bought and sold "over the counter" (OTC). OTC dealing involves buyers and sellers dealing with each other by telephone or electronically on the basis of prices that are displayed electrionically, usually by commercial information vendors such as Reuters and Bloombergs.
There are also eurosecurities, which are securities that are issued outside their domestic market into more than one jurisdiction. They are generally listed on the Luxembourg Stock Exchange or admitted to listing in London. The reasons for listing eurobonds include regulatory and tax considerations, as well as the investment restrictions.
International debt markets
London is the centre of the eurosecurities markets. There was a huge rise in the eurosecurities market in London in the early 1980s. Settlement of trades in eurosecurities is currently affected through two European computerised systems called Euroclear (in Belgium) and Clearstream (formerly Cedelbank in Luxembourg).
- Cash (Spot)
In the United States, the offer and sale of securities is either registered pursuant to a registration statement that is filed with the Securities and Exchange Commission (SEC) or are offered and sold pursuant to an exemption therefrom. Dealing in securities is heavily regulated by both the federal authorities (chiefly SEC) and state authorities. In addition the industry is heavily self policed by Self Regulatory Organizations (SRO's), such as the NASD or the MSRB.
Due to the difficulty of creating a general definition that covers all securities, the SEC attempts to define "securities" exhaustively (and not very precisely) as: "any note, stock, treasury stock, security future, bond, debenture, certificate of interest or participation in any profit-sharing agreement or in any oil, gas, or other mineral royalty or lease, any collateral-trust certificate, preorganization certificate or subscription, transferable share, investment contract, voting-trust certificate, certificate of deposit for a security, any put, call, straddle, option, or privilege on any security, certificate of deposit, or group or index of securities (including any interest therein or based on the value thereof), or any put, call, straddle, option, or privilege entered into on a national securities exchange relating to foreign currency, or in general, any instrument commonly known as a "security"; or any certificate of interest or participation in, temporary or interim certificate for, receipt for, or warrant or right to subscribe to or purchase, any of the foregoing; but shall not include currency or any note, draft, bill of exchange, or banker's acceptance which has a maturity at the time of issuance of not exceeding nine months, exclusive of days of grace, or any renewal thereof the maturity of which is likewise limited." - Section 3a item 10 of the 1934 Act.
