it seems that they never released this information in their reports, only showed they invested in Japan? where is the money now? sorry for mistype?
I am not sure you are investors or shorts on Baidu. But whatever, it's not the game for you. If you shorted Baidu at 107, and you are worried too much, then you better cover as soon as possible.
Baidu don't put much money in Japan. Even if Japan disappear, not much difference for BIDU's next earning report. Don't worry.
Why do you check their 10-Q and 10-K? Yahoo message boards not responsible to your silly question. If you are a big investors for Baidu, and not happy with this company, you can sell your shares and go away.
