You plan to tender in cash for 100% of Company T's shares\nbut are unsure how high a price to offer. The main complication is this:\nthe value of Company T depends directly on the outcome of a major oil\nexploration project it is currently undertaking. Indeed, the very\nviability\nof Company T depends on the exploration outcome. If the project fails, the\ncompany under current management will be worth nothing--$0/share. But if\nthe project succeeds, the value of the company under current management\ncould be as high as $100/share. All share values between $0 and $100 are\nconsidered equally likely. By all estimates, the company will be worth\nconsiderably more in the hands of Company A than under current management.\nIn fact, whatever the ultimate value under current management, the company\nwill be worth fifty percent more under the management of A than under\nCompany T. If the project fails, the company is worth $0/share under\neither\nmanagement. If the exploration project generates a $50/share value under\ncurrent management, the value under Company A is $75/share. Similarly, a\n$100/share value under Company T implies a $150/share value under Company\nA,\nand so on.\n\n The board of directors of Company A has asked you to determine the\nprice\nthey should offer for Company T's shares. This offer must be made now,\nbefore the outcome of the drilling project is known. From all indications,\nCompany T would be happy to be acquired by Company A, provided it is at a\nprofitable price. Moreover, Company T wishes to avoid, at all cost, the\npotential of a takeover bid by any other firm. You expect Company T to\ndelay a decision on your bid until the results of the project are in, then\naccept or reject your offer before the news of the drilling results reaches\nthe press.\n\n Thus, you (Company A) will not know the results of the exploration\nproject\nwhen submitting your price offer, but Company T will know the results when\ndeciding whether or not to accept your offer. In addition, Company T will\naccept any offer by Company A that is greater than the (per share) value of\nthe company under current management. Thus, if you offer $50/share, for\ninstance, Company T will accept if the value of the company to Company T is\nanything less than $50.\n\n As the representative of Company A, you are deliberating over price\noffers\nin the range of $0/share (this is tantamount to making no offer at all) to\n$150/share.

In addition, Company T will\naccept any offer by Company A that is greater than the (per share) value of\nthe company under current management. Thus, if you offer $50/share, for\ninstance, Company T will accept if the value of the company to Company T is\nanything less than $50.\n\n As the representative of Company A, you are deliberating over price\noffers\nin the range of $0/share (this is tantamount to making no offer at all) to\n$150/share. What price offer per share would you tender for Company T's\nstock?\n\n $______ per/share\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n", "subject": "RE: Extra credit", "date": "2001-05-13 09:16:00-07:00", "from": "john.arnold@enron.com", "to": "epao@mba2002.hbs.edu"}
