Firms A and B are competitors with very similar assets and business risks. Both are all-equity firms with after-tax cash flows of $10 per year forever, and both have an overall cost of capital of 10 per cent. Firm A is thinking of buying Firm B. The after-tax cash flow from the merged firm would be $21 per year. Does the merger generate synergy? What is V_B? What is ΔV?
