Final answer:
When KSA is 100% equity financed, the after-tax cash flow in year 1 is $60 million. The current market value of KSA in this case is $400 million.
Step-by-step explanation:
To calculate the after-tax cash flow for KSA in year 1 when it is 100% equity financed, we need to consider the corporate tax rate. The after-tax cash flow can be calculated as the net cash flow multiplied by (1 - tax rate). In this case, the after-tax cash flow would be $80 million x (1 - 0.25) = $60 million.
To calculate the current market value of KSA when it is 100% equity financed, we can use the formula: Market value = After-tax cash flow / Expected rate of return. In this case, the market value would be $60 million / 0.15 = $400 million.
If KSA is financed by both debt and equity and has an outstanding loan of $40 million, the total after-tax cash flow in year 1 would be the sum of the net cash flow and the interest savings from the loan. In this case, it would be $80 million + ($40 million x 0.05) = $82 million.
