Trying to Add Value - Buying and Selling Divisions"

Three large local companies (PepsiCo, Frontier, and General Electric) have all announced major acquisitions or divestitures in the last 10 days.For every buyer there is a seller and vice-versa, and each side of the transaction must be thinking that the transaction will create EVA (Economic Value will be Added for the Enterprise), else they wouldn't do it.Look at these three situations. What is common and what is different for the firms making the analysis?You could wrote a dissertation here... Please comment in the narrow framework using the formula for EVA (NPV of cash flows is less than NPV of cash spent, or if selling, the NPV of cash received is more than the NPV of cash you would have received in the future).
