Answer 1.
Face Value of Bonds = $48,000,000
Annual Coupon Rate = 10.00%
Semiannual Coupon Rate = 5.00%
Semiannual Coupon = 5.00% * $48,000,000
Semiannual Coupon = $2,400,000
Time to Maturity = 20 years
Semiannual Period = 40
Annual Interest Rate = 12.00%
Semiannual Interest Rate = 6.00%
Issue Price of Bonds = $2,400,000 * PVA of $1 (6.00%, 40) +
$48,000,000 * PV of $1 (6.00%, 40)
Issue Price of Bonds = $2,400,000 * 15.04630 + $48,000,000 *
0.09722
Issue Price of Bonds = $40,777,680
Answer 2.
Face Value of Bonds = $48,000,000
Semiannual Coupon = $2,400,000
Semiannual Period = 40
Annual Interest Rate = 9.00%
Semiannual Interest Rate = 4.50%
Issue Price of Bonds = $2,400,000 * PVA of $1 (4.50%, 40) +
$48,000,000 * PV of $1 (4.50%, 40)
Issue Price of Bonds = $2,400,000 * 18.40158 + $48,000,000 *
0.17193
Issue Price of Bonds = $52,416,432
