Cash flow mapping is a method used in financial risk management to decompose the risk of a bond into the risk of each of the bond's cash flows. This method allows for a more granular analysis of the bond's risk profile, as it considers each cash flow as a separate risk factor. The present value of each cash flow is then mapped onto the risk factors for zero-coupon bonds of the same maturity. This approach provides a detailed understanding of the bond's risk exposure, making it easier to manage and mitigate potential losses.

Choice A is incorrect. Principal mapping is a method used to manage the risk associated with the principal repayment of a bond, not its individual cash flows. It does not break down the risk into each of the bond's individual cash flows.

Choice B is incorrect. Duration mapping involves assessing interest rate risk by considering how changes in interest rates affect a bond's duration, which represents the weighted average time until a bond's cash flows are received. While it does consider cash flows, it does not break down risks into each individual cash flow.

Choice D is incorrect. Present value mapping involves discounting future cash flows to their present value to assess their worth today. Although this method considers individual cash flows, it doesn't specifically map out the risks associated with each one.

Things to Remember

• Cash flow mapping helps in understanding the risk profile of a bond by analyzing each cash flow separately.
• It allows for a more detailed risk assessment compared to other methods like principal mapping or duration mapping.
• By mapping the present value of each cash flow onto the risk factors for zero-coupon bonds of the same maturity, a comprehensive risk exposure analysis can be conducted.
• Managing and mitigating potential losses becomes easier with a thorough understanding of the bond's risk through cash flow mapping.
