Microsoft issued a short, murky statement Sunday afternoon saying it has suggested a limited alignment with Yahoo. It does not explain its proposal. Perhaps it's thinking along the lines of the deal Yahoo is supposed to be negotiating with Google, perhaps a partial acquisition (perhaps Yahoo's Panama platform).

Microsoft also said in its statement that it could reopen talks to acquire the whole of the company depending...depending apparently on Yahoo being open to a friendly takeover.

“In light of developments since the withdrawal of the Microsoft proposal to acquire Yahoo! Inc., Microsoft announced that it is continuing to explore and pursue its alternatives to improve and expand its online services and advertising business. Microsoft is considering and has raised with Yahoo! an alternative that would involve a transaction with Yahoo! but not an acquisition of all of Yahoo! Microsoft is not proposing to make a new bid to acquire all of Yahoo! at this time, but reserves the right to reconsider that alternative depending on future developments and discussions that may take place with Yahoo! or discussions with shareholders of Yahoo! or Microsoft or with other third parties.

“There of course can be no assurance that any transaction will result from these discussions.”

“Yahoo! has confirmed with Microsoft that it is not interested in pursuing an acquisition of all of Yahoo! at this time. Yahoo! and its Board of Directors continue to consider a number of value maximizing strategic alternatives for Yahoo!, and we remain open to pursuing any transaction which is in the best interest of our stockholders. Yahoo!'s Board of Directors will evaluate each of our alternatives, including any Microsoft proposal, consistent with its fiduciary duties, with a focus on maximizing stockholder value.”
