mikkl666 writes "In response to an open letter from Steve Ballmer, Yahoo! posted a press release claiming that Microsoft's offer 'substantially undervalues Yahoo!' and is therefore not in the best interest of the company. They also bemoan that the letter 'mischaracterizes the nature of our discussions' and that the threat to make an offer directly to the shareholders is 'counterproductive and inconsistent with the stated objective of a friendly transaction'. Nevertheless, they explicitly point out that a transaction with Microsoft is still an option, but only if they are willing to pay 'a price that fully recognizes the value of Yahoo!'"
