Mega Service Corporation (MSC) is offering to exchange 2.5 shares of its own stock for each share of target firm Norman Corporation stock as consideration for a proposed merger. There are 10 million Norman Corp shares outstanding, and its stock price was $60 before the merger offer. MSCs pre-offer stock price was $30. What is the control premium percentage offered? Now suppose that, when the merger is consummated eight months later, MSCs stock drops to $25. At that point, what is the control premium percentage and total transaction value?
