A bond is an instrument of indebtedness (fixed-income securities) under which the issuer owes the holders a debt and, is obliged to pay them interest (the coupon) or to repay the principal at a specific date. Interest is payable at fixed intervals (usually semiannual or annual). Usually the bond is negotiable, i.e. the ownership of the instrument can be transferred in the secondary market.
