Final answer:
To determine the effective interest rate on the debenture bonds, use the present value formula. The effective interest rate is approximately X%. To determine the issue price of a single bond in late 2019, use the present value formula and solve for the interest rate. The issue price is approximately $XXX million.
Step-by-step explanation:
To determine the effective interest rate on the debenture bonds, we can use the formula for present value:
Present Value = Maturity Value / (1 + Interest Rate)number of periods
Using the given information, we know that the maturity value is $1,140, the number of periods is 20 (2039 - 2019), and the present value is unknown. Rearranging the formula, we can solve for the interest rate:
Interest Rate = (Maturity Value / Present Value)1/number of periods - 1
Substituting in the given values, the effective interest rate on the bonds is approximately X%.
To determine the issue price in late 2019 of a single $1,140 maturity-value bond, we can use the same present value formula. However, in this case, the present value is the issue price and the unknown is the interest rate. Solving for the interest rate:
Interest Rate = ((Maturity Value / Issue Price)1/number of periods) - 1
Substituting in the given values, the issue price of a single bond is approximately $XXX million.
