Firm Yahoo has attracted the attention of Firm Verizon because of its poor operating performance. Firm Verizon believes that the way Firm Yahoo is managed is inefficient and that replacing the current management team would increase the cash flow of Yahoo by $25,000 every year up to perpetuity. Firm Yahoo has 50,000 shares outstanding and is not listed.

Firm Verizon has 250,000 shares outstanding that are currently trading at $40/share. Firm Verizon already owns a 1% stake in Firm Yahoo. Firm Yahoo has two other shareholders, ABC and DEF. Both of them hold a 49.5% stake in Firm Yahoo. To change the management team, Firm Verizon needs to get control of Firm Yahoo (at least 50% of shares).

Firm Verizon hires Levan Brothers, a prestigious investment bank, to get advice on the transaction. Levan Brothers estimates that the value of one share of Firm Yahoo under the current management team is $15 per share. They also advise Firm Verizon to pay a premium for the acquisition of Yahoo and to offer ABC and DEF $17 in cash for every share of Firm Yahoo. Fees charged by Levan Brothers to Firm Verizon are $6,000. Assume that there are no taxes and markets are perfectly efficient. The appropriate annual discount rate is 10%. 

**Note: that Investment bankers usually receive a success fee, i.e., they are paid only if the transaction takes place, their fees are not a sunk cost and the fee is typically paid by the acquiring firm.

 how do I compute the maximum price per share that Firm Verizon is willing to pay to acquire the remaining 99% of Firm Yahoo via an all-cash offer.

after that how can I compute ABC's gains if it accepts the all-cash offer of $17/share. and if ABC believes that DEF will accept the offer and tender its shares. What is the optimal strategy for ABC: should they accept the offer or decline the offer? then What will happen if DEF also believes that ABC will tender its shares and what's the minimum share price Firm Verizon should offer to ABC and/or DEF to avoid that. at the end how do I compute the gains or losses per share for Firm Verizon if an all-cash offer to acquire 99% of Firm Yahoo is made at a price of $20. and if we assume that ABC always believes that DEF will accept the cash offer and vice versa, what is the likelihood that the inefficient management team is replaced some day?
