A well-known industrial firm has issued $1000 bonds that carry 4% nominal annual interest paid semiannually. The bonds mature 20 years from now, at which time the industrial firm will redeem them for face value plus the terminal semiannual interest payment. From the financial pages of your newspaper you learn that the bonds may be purchased for $715 each ($710 for the bond plus a $5 sales commission).What nominal annual rate of return would you receive if you purchased the bond now and held it to maturity 20 years from now? Solution: 1. NPW=PW of Benefits - PW of Costs=0 o Interest received every half year is A=$ o Number of compounding period na PW of Benefits-A(P/A, i, n)+F(P/F,i-,n); o PW of Costs - 2. Find out in using trial and error Try i-3%: NPW- Try i=3.5%: NPW- o Performing linear interpolation: i- 3. Find nominal and effective rate: Nominal rate % Effective rate - %
