Answer:
The interest rate on corporate bond is 7.87 percent.
Explanation:
The yield on 7-year municipal bond = 4.8%
Given marginal tax rate = 39 percent
Now calculate the interest rate on 7 year corporate bond that has equal risk.
Use the below formula. Here, yield from both type of bond is equated that is yield from corporate bond and yield from municipal bond because it is given that both gives same return after tax.
Interest rate on corporate bond × (1-tax rate) = Municipal bond yield
Interest rate on corporate bond × (1- 0.39) = 4.8
