Consider a corporation whose expected EBIT is $10M each year and for ever. Depreciation equals investment. The tax rate on EBIT is 30%. The corporation has only one piece of debt, a fully amortizing 30-year bond with fixed yearly payments and an interest rate of 10%. After the bond expires, the corporation plans to remain debt-free. Investors would require a 15% return from an unlevered investment in this corporation. The market value of the corporation is $51M. What is the face value of the debt? Use an APV approach given the fact that the capital stucture is not stable.
