Yahoo! has issued a press release responding to Microsoft concerning may of the issues that appear to be keeping the two apart. But at the end, Yahoo! states that it all comes down to money. In the statement it says:

In conclusion, please allow us to restate our position, so there can be no confusion. We are open to all alternatives that maximize stockholder value. To be clear, this includes a transaction with Microsoft if it represents a price that fully recognizes the value of Yahoo! on a standalone basis and to Microsoft, is superior to our other alternatives, and provides certainty of value and certainty of closing. Lastly, we are steadfast in our commitment to choosing a path that maximizes stockholder value and we will not allow you or anyone else to acquire the company for anything less than its full value.

Seems like Yahoo has made their position clear. Now it is up to Microsoft to make the next move.
