Special types of bonds: The most important thing to consider when looking to invest in bonds is what organization is issuing the bond. This can affect the interest rates as well as the risk associated with the bond. The most common type of bond is the corporate bond. These can vary widely in terms of maturity date, and depending on the company’s credit rating, in interest rate as well. Some corporate bonds set out conditions in which they could be converted into stock in the company [1].
