Question

The yield to maturity for 15-year bonds is as follows for four different bond rating categories. Use Appendix B and Appendix D for an approximate answer but calculate your final answer using the formula and financial calculator methods. Aaa 8.60% Aa1 8.80% Aa2 9.00% Aa3 10.00%

The bonds of Falter Corporation were rated as Aa1 and issued at par a few weeks ago. The bonds have just received a new rating of Aa3. Determine the new price of the bonds, assuming a 15-year maturity and semiannual interest payments

Explanation / Answer

Answer

With a Aa1 rating at issue, the coupon rate is 8.80.0% annually or 4.40% semiannually. With a downgrading to Aa3, the new yield to maturity is 10% or 5% semiannually

Present value of interest payments

PV A = A × PV IFA (n = 30, i = 5%)

PV A = $44 × 15.37245= $676.39

Present value of principal payment at maturity

PV = FV × PV IF (n = 30, i = 5%)

PV = $1,000 × 0.2314= $231.40

Total present value or price of a bond = PV of interest payments 9+ pV of principal = $907.80
