Yahoo and AOL are in discussions to combine their web operations reports the WSJ. The move is aimed at thwarting Microsoft’s bid to acquire Yahoo.

The terms being discussed between AOL would fold into Yahoo and make a cash investment in return for about 20% of the combined entity. The deal which does not include AOL’s dial-up access business values AOL at about $10 billion. Yahoo would use the AOL cash investment and put up additional funds to buy back several billion dollars worth of its own stock at a price somewhere in the middle of the range between $30 and $40 a share reports the WSJ.
