Yahoo had to do this. They had been hanging onto the belief that the IRS wouldn't tax their Alibaba spin out, a belief that they and their tax accountants alone believed. Most telling is that Yahoo was up after the markets closed on this news. Heck Bloomberg just sent me a note saying the sentiment of the news on Yahoo was very positive, even the machines like this news:) Sadly this probably means 3 things are going…
Isn't Yahoo Japan being spun off from the Alibaba portion? Ie. all that remains of the current "Yahoo" company will be its Alibaba stake.
