Finance

Finance studies and addresses the ways in which individuals, businesses, and organizations raise, allocate, and use monetary resources over time, taking into account the risks entailed in their projects. The term finance may thus incorporate any of the following:
The study of money and other assets; The management and control of those assets; Profiling and managing project risks; The science of managing money; As a verb, "to finance" is to provide funds for business or for an individual's large purchases (car, home, etc.). The activity of finance is the application of a set of techniques that individuals and organizations (entities) use to manage their financial affairs, particularly the differences between income and expenditure and the risks of their investments.
An entity whose income exceeds its expenditure can lend or invest the excess income. On the other hand, an entity whose income is less than its expenditure can raise capital by borrowing or selling equity claims, decreasing its expenses, or increasing its income. The lender can find a borrower, a financial intermediary, such as a bank or buy notes or bonds in the bond market. The lender receives interest, the borrower pays a higher interest than the lender receives, and the financial intermediary pockets the difference.
A bank aggregates the activities of many borrowers and lenders. A bank accepts deposits from lenders, on which it pays the interest. The bank then lends these deposits to borrowers. Banks allow borrowers and lenders, of different sizes, to coordinate their activity. Banks are thus compensators of money flows in space.
A specific example of corporate finance is the sale of stock by a company to institutional investors like investment banks, who in turn generally sell it to the public. The stock gives whoever owns it part ownership in that company. If you buy one share of XYZ Inc, and they have 100 shares outstanding (held by investors), you are 1/100 owner of that company. Of course, in return for the stock, the company receives cash, which it uses to expand its business in a process called "equity financing". Equity financing mixed with the sale of bonds (or any other debt financing) is called the company's capital structure.
Finance is used by individuals (personal finance), by governments (public finance), by businesses (corporate finance), etc., as well as by a wide variety of organizations including schools and non-profit organizations. In general, the goals of each of the above activities are achieved through the use of appropriate financial instruments, with consideration to their institutional setting.
Finance is one of the most important aspects of business management. Without proper financial planning a new enterprise is unlikely to be successful. Managing money (a liquid asset) is essential to ensure a secure future, both for the individual and an organization.

Bond

In finance, a bond is a debt security, in which the authorized issuer owes the holders a debt and is obliged to repay the principal and interest (the coupon) at a later date, termed maturity. Other stipulations may also be attached to the bond issue, such as the obligation for the issuer to provide certain information to the bond holder, or limitations on the behavior of the issuer. Bonds are generally issued for a fixed term (the maturity) longer than ten years. U.S Treasury securities issue debt with life of ten years or more, which is a bond. New debt between one year and ten years is a note, and new debt less than a year is a bill.
A bond is simply a loan, but in the form of a security, although terminology used is rather different. The issuer is equivalent to the borrower, the bond holder to the lender, and the coupon to the interest. Bonds enable the issuer to finance long-term investments with external funds. Certificates of deposit (CDs) or commercial paper are considered money market instruments.
In some nations, both bonds and notes are used irrespective of the maturity. Market participants normally use bonds for large issues offered to a wide public, and notes for smaller issues originally sold to a limited number of investors. There are no clear demarcations. There are also "bills" which usually denote fixed income securities with three years or less, from the issue date, to maturity. Bonds have the highest risk, notes are the second highest risk, and bills have the least risk. This is due to a statistical measure called duration, where lower durations have less risk, and are associated with shorter term obligations.
Bonds and stocks are both securities, but the difference is that stock holders own a part of the issuing company (have an equity stake), whereas bond holders are in essence lenders to the issuer. Also bonds usually have a defined term, or maturity, after which the bond is redeemed whereas stocks may be outstanding indefinitely. An exception is a consol bond, which is a perpetuity (i.e. bond with no maturity).

Goverment bond

A government bond is a bond issued by a national government denominated in the country's own currency. Bonds issued by national governments in foreign currencies are normally referred to as sovereign bonds.
RiskGovernment bonds are usually referred to as risk-free bonds, because the government can raise taxes or simply print more money to redeem the bond at maturity. Some counter examples do exist where a government has defaulted on its domestic currency debt, such as Russia in 1998- the "ruble crisis" , though this is very rare.
As an example, in the US, Treasury securities are denominated in US dollars and are the safest US dollar investments. In this instance, the term risk-free means free of credit risk. However, other risks still exist: such as currency risk for foreign investors (for example non-US investors of US Treasuries would have received lower returns in 2004 because the value of the US dollar declined against most other currencies). Secondly, there is inflation risk - in that the principal repaid at maturity will have less purchasing power than anticipated if the inflation outturn is higher than expected. Many governments issue inflation-indexed bonds, which protect investors against inflation risk.
An example of somewhat risky bonds issued by a government can be given with countries that have less than perfect capabilities of conducting financial policies. Such an example is Bulgaria due to its being dependent on the world economy and economic institutions much more than, say, the US. Some of this country's bonds were only given an A-scale rating after 2004. As of February 2006 Standard & Poor's rates Bulgaria's long-term debt denominated in domestic currency at BBB+. And this rating is the result of almost a decade of constantly decreasing risk (and increasing ratings). We should also note that this country's short-term debt is in fact currently rated A.
IssuanceGovernment bonds are issued through agencies that are part of the government's treasury department, for example
Bunds are bonds issued by the German Finance Agency, denominated in euros Gilts are bonds issued by the UK Debt Management Office and are denominated in sterling US Treasuries are issued by the Bureau of the Public Debt

Performance bond

A performance bond is a surety bond issued by an insurance company to guarantee satisfactory completion of a project by a contractor.
For example, a contractor may cause a performance bond to be issued in favor of a client for whom the contractor is constructing a building. If the contractor fails to construct the building according to the specifications laid out by the contract (most often due to the bankruptcy of the contractor), the client is guaranteed compensation for any monetary loss up to the amount of the performance bond.
Performance bonds are commonly used in the development of real property, where an owner or investor may require the developer to assure that contractors or project managers procure such bonds in order to guarantee that the value of the work will not be lost in the case of an unfortunate event (such as insolvency of the contractor).
The term is also used to denote a collateral deposit intended to secure a Futures contract, commonly known as margin.
Performance bonds have been around since 2,750 BC and more recently, the Romans developed laws of surety around 150 AD the principles of which, still exist.
