Q. A 77-year $1,000\$1,000 bond has coupons paid quarterly at a rate of 9%9\%. The bond can be redeemed early in 33 years at a price of $1,070\$1,070. If the bond is valued at $900\$900, what is the highest and lowest return an investor can get and under what conditions?
  1. Calculate Total Coupon Payments: Calculate the total coupon payments received if held for 77 years.\newlineQuarterly interest rate is 9%9\% per year, so each quarter it's 9%/4=2.25%9\% / 4 = 2.25\%.\newlineEach quarter, the payment is ($1,000×2.25%)=($22.50)(\$1,000 \times 2.25\%) = (\$22.50).\newlineThere are 44 quarters in a year, so for 77 years, there are 4×7=284 \times 7 = 28 quarters.\newlineTotal coupon payments = 28×($22.50)=($630)28 \times (\$22.50) = (\$630).
  2. Calculate Total Return: Calculate the total return if the bond is held to maturity (7 ext{ years}\(\newline)).\newlineTotal return = Total coupon payments + Redemption value - Purchase price.\newlineRedemption value at maturity is the face value, which is \$\$1,000\).\(\newline\)Total return = \(\$630\) + \(\$1,000\) - \(\$900\) = \(\$730\).
  3. Calculate Annualized Return: Calculate the annualized return if held for \(7\) years.\(\newline\)Annualized return = \((\text{Total return} / \text{Purchase price}) / \text{Number of years}\).\(\newline\)Annualized return = \((\$(730) / \$(900)) / 7\).\(\newline\)Annualized return = \(0.0811\) or \(8.11\)\%.
  4. Calculate Total Return Early Redemption: Calculate the total return if the bond is redeemed early after \(3\) years.\(\newline\)Total coupon payments for \(3\) years = \(3\) years \(\times\) \(4\) quarters/year \(\times\) \(\$22.50\) = \(\$270\).\(\newline\)Total return = Total coupon payments for \(3\) years + Early redemption value - Purchase price.\(\newline\)Early redemption value is \(\$1,070\).\(\newline\)Total return = \(\$270\) + \(\$1,070\) - \(\$900\) = \(\times\)\(0\).
  5. Calculate Annualized Return Early Redemption: Calculate the annualized return if redeemed early after \(3\) years.\(\newline\)Annualized return = \((\text{Total return} / \text{Purchase price}) / \text{Number of years}\).\(\newline\)Annualized return = \((\$(440) / \$(900)) / 3\).\(\newline\)Annualized return = \(0.1622\) or \(16.22\%\).
  6. Determine Highest and Lowest Return: Determine the highest and lowest return. The highest return is if the bond is redeemed early at \(16.22\%\). The lowest return is if the bond is held to maturity at \(8.11\%\).
