The document outlines several types of risks associated with bond investments: 1) Interest rate risk, inflation risk, reinvestment risk, and credit risk pose the greatest threats as they relate to changes in rates that can decrease bond prices or the value of future cash flows. 2) Call risk, liquidity risk, and event risk also impact bond holders, such as the bond being paid off early, difficulty selling the bond, or external events negatively affecting the issuer. 3) Investors in foreign bonds face additional exchange rate risk if the foreign currency fluctuates against the domestic currency.
