7. Suppose company ABC will be worth either 180 M or 100 M depending on whether the economy is strong or weak in one year. Both states of the economy are equally likely. The current risk-free rate is 5% and the cost of equity if the company is 100% equity financed is 12%. Assume perfect world a) What is the current value of ABC if it is all-equity financed? b) What is the (before-tax) cost of debt, ra, if ABC borrows $80 M? Explain c) What is the (before tax) cost of debt if ABC borrows $ 99 M? Hint: determine whether the debt is risky or not. If "yes", estimate cost of risky debt a) What is the cost of equity if ABC borrows $ 99 M? If you have not completed part c) you may assume that r = 7% b) What is weighted average cost of capital (rwACC) if ABC borrows $ 99 M? a) (5 points) On the debt-to-value-ratio (as X) and Expected rate of return (as Y) plane draw graphs of r Iwace, IE, and ra Be specific, indicate on the graph all important / pivotal points / values. You may use Excel and include your spreadsheet or draw your graph on the grid paper and include scan of your graph
