A Bond (not James) is considered as various things – in this case, a loan in which the lender is a common everyday consumer and the borrower is the government, an agency, or a company. The U.S. Treasury, municipalities, and companies, issue or sell Bonds to obtain large amounts of money for the advancement of the agency. Purchase of Bonds enables the borrower to invest cash with the purpose of gaining interest on the amount of the Bond, although some Bonds don’t produce interest. A Bond is considered a security (like a stock) but it is rated as a debt, whereas a stock is regarded as equity.   

Because Bonds are in actuality loans, the amount of the Bond is the principle, and interest is paid on the principle: usually at a fixed rate. Bond Insurance is protection for the lender against default. A premium for the insurance is paid for by the issuer of the Bond.  Insurance companies commit to pay the principle and interest of a Bond if the issuer is unable to meet the requirements of the agreement. Some insurance companies deal exclusively with Bond Insurance.

Classification of Bonds is made with regard to whether or not they are secure or unsecure, maturity rating, tax status, quality, and safety in terms of whether or not the issuer is financially reliable to repay the Bond. Bond Insurance, therefore, will correspond to the rating of the Bond and is calculated as the possible of risk of failure to repay the Bond. The only Bonds that are not usually insured are Government Bonds, since the risk of failure to repay is negligible.
