The current yield on a bond is equal to the annual interest divided by the d. current market price.
Issue price: This is the price at which the bond was originally sold. It doesn't reflect the current market price, which may be different.
Maturity value: This is the face value of the bond that the issuer will pay back at maturity. It also doesn't reflect the current market price.
Face amount: This is the amount of money the issuer will pay back at maturity, and it's usually the same as the maturity value. It still doesn't reflect the current market price, which is what matters for calculating current yield.
Current market price: This is the price at which the bond is currently trading in the market. This is the relevant price for calculating current yield because it represents the actual cost of investing in the bond.
Current par value: This is the same as the face value and doesn't reflect the current market price.
Therefore, the correct answer is d. current market price.
