According to sources familiar with the matter, Microsoft has signed NDA with Yahoo to begin talks about bidding for the assests of Yahoo reported New York Times today. Microsoft will join the private equity firms like Silver Lake, TPG Capital and others who were also signed similar NDA’s with Yahoo last month about buying Yahoo. Even though Microsoft has several year Search deal with the company, other assets of Yahoo will largely overlap with Microsoft assests. Some of them are Yahoo.com, Yahoo Mail, Yahoo Messenger, Yahoo News, etc,. Microsoft may not need those assets but they are closely related to search, so it may help other firms to buy Yahoo by financing the deal to keep its search deal in action as it is today. Lets see how the deal plays out..
