finance review : Bond 1

In finance, a bond is a debt security, in which the authorized issuer owes the holders a debt and, depending on the terms of the bond, is obliged to pay interest (the coupon) and/or to repay the principal at a later date, termed maturity. It is a formal contract to repay borrowed money with interest at fixed intervals.[1]

Thus a bond is like a loan: the issuer is the borrower, the bond holder is the lender, and the coupon is the interest. Bonds provide the borrower with external funds to finance long-term investments, or, in the case of government bonds, to finance current expenditure. Certificates of deposit (CDs) or commercial paper are considered to be money market instruments and not bonds.

Bonds and stocks are both securities, but the major difference between the two is that stock-holders are the owners of the company (i.e., they have an equity stake), whereas bond holders are lenders to the issuers. Another difference is that 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).

Issuing bonds
Bonds are issued by public authorities, credit institutions, companies and supranational institutions in the primary markets. The most common process of issuing bonds is through underwriting. In underwriting, one or more securities firms or banks, forming a syndicate, buy an entire issue of bonds from an issuer and re-sell them to investors. The security firm takes the risk of being unable to sell on the issue to end investors. However government bonds are instead typically auctioned.

Features of bonds
The most important features of a bond are:

nominal, principal or face amount — the amount on which the issuer pays interest, and which has to be repaid at the end.
issue price — the price at which investors buy the bonds when they are first issued, which will typically be approximately equal to the nominal amount. The net proceeds that the issuer receives are thus the issue price, less issuance fees.
maturity date — the date on which the issuer has to repay the nominal amount. As long as all payments have been made, the issuer has no more obligations to the bond holders after the maturity date. The length of time until the maturity date is often referred to as the term or tenor or maturity of a bond. The maturity can be any length of time, although debt securities with a term of less than one year are generally designated money market instruments rather than bonds. Most bonds have a term of up to thirty years. Some bonds have been issued with maturities of up to one hundred years, and some even do not mature at all. In early 2005, a market developed in euros for bonds with a maturity of fifty years. In the market for U.S. Treasury securities, there are three groups of bond maturities:
short term (bills): maturities up to one year;
medium term (notes): maturities between one and ten years;
long term (bonds): maturities greater than ten years.
coupon — the interest rate that the issuer pays to the bond holders. Usually this rate is fixed throughout the life of the bond. It can also vary with a money market index, such as LIBOR, or it can be even more exotic. The name coupon originates from the fact that in the past, physical bonds were issued which had coupons attached to them. On coupon dates the bond holder would give the coupon to a bank in exchange for the interest payment.

Indentures and Covenants — An indenture is a formal debt agreement that establishes the terms of a bond issue, while covenants are the clauses of such an agreement. Covenants specify the rights of bondholders and the duties of issuers, such as actions that the issuer is obligated to perform or is prohibited from performing. In the U.S., federal and state securities and commercial laws apply to the enforcement of these agreements, which are construed by courts as contracts between issuers and bondholders. The terms may be changed only with great difficulty while the bonds are outstanding, with amendments to the governing document generally requiring approval by a majority (or super-majority) vote of the bondholders.
High yield bonds are bonds that are rated below investment grade by the credit rating agencies. As these bonds are more risky than investment grade bonds, investors expect to earn a higher yield. These bonds are also called junk bonds.
coupon dates — the dates on which the issuer pays the coupon to the bond holders. In the U.S. and also in the U.K. and Europe, most bonds are semi-annual, which means that they pay a coupon every six months.
Optionality: Occasionally a bond may contain an embedded option; that is, it grants option-like features to the holder or the issuer:
Callability — Some bonds give the issuer the right to repay the bond before the maturity date on the call dates; see call option. These bonds are referred to as callable bonds. Most callable bonds allow the issuer to repay the bond at par. With some bonds, the issuer has to pay a premium, the so called call premium. This is mainly the case for high-yield bonds. These have very strict covenants, restricting the issuer in its operations. To be free from these covenants, the issuer can repay the bonds early, but only at a high cost.
Putability — Some bonds give the holder the right to force the issuer to repay the bond before the maturity date on the put dates; see put option. (Note: "Putable" denotes an embedded put option; "Puttable" denotes that it may be putted.)
call dates and put dates—the dates on which callable and putable bonds can be redeemed early. There are four main categories.
A Bermudan callable has several call dates, usually coinciding with coupon dates.
A European callable has only one call date. This is a special case of a Bermudan callable.
An American callable can be called at any time until the maturity date.
A death put is an optional redemption feature on a debt instrument allowing the beneficiary of the estate of the deceased to put (sell) the bond (back to the issuer) in the event of the beneficiary's death or legal incapacitation. Also known as a "survivor's option".
sinking fund provision of the corporate bond indenture requires a certain portion of the issue to be retired periodically. The entire bond issue can be liquidated by the maturity date. If that is not the case, then the remainder is called balloon maturity. Issuers may either pay to trustees, which in turn call randomly selected bonds in the issue, or, alternatively, purchase bonds in open market, then return them to trustees.
convertible bond lets a bondholder exchange a bond to a number of shares of the issuer's common stock.
exchangeable bond allows for exchange to shares of a corporation other than the issuer.
