Yahoo (NSDQ: YHOO) has filed a copy of a letter CEO Jerry Yang and Chairman Roy Bostock sent to the troops late on Friday. The message: pretty much the same as the rest of the company’s time-buying public statements: “First, we want to emphasize that absolutely no decisions have been made — and, despite what some people have tried to suggest, there’s certainly no integration process underway. this proposal is just that — a proposal. And it was only made in the last 24 hours. You can be sure the board is going to review it thoughtfully and carefully, and do what’s right for our great company. Microsoft’s proposal is one of many options that we’re evaluating in order to maximize value for our shareholders and employees over the long-term. That’s why we will respond to Microsoft (NSDQ: MSFT) after our board has completed a careful review of all of our strategic alternatives.”
