Instead of organizing a trip to china i would just love to sit down in a room for an hour with the two lead auditors from each accountant (MB & ?)assigned to NIV and ask where the problem lies with the company. Not sure if thats breaking some type of ethical or professional code of conduct but who gives a cr.p its my money. BTW i would by happy to pay someone for that service.
I think the same analysis would apply to the board as it would to the auditor, attorneys, consultants, etc., in that all of them will be bound by confidentiality to the company, and as such couldn't share anything with any of us.
I am by no means an expert in securities law, but generally any publically traded company is restricted against sharing non-public information with a selected class. Basically if it is information worth knowing, it has to be released in a filing.
By biggest worry is that any negative news will send the stock down to near zero. But at this point, I think there are really only two options: One sell your shares and take a significant haircut on your initial investment. Two, be patient and hope that the fraud, if any, is fairly insignificant as compared to the ability of the company to generate revenue.
You'll never know if you dont ask. WHY DONT WE ASK SOMEONE. At least we would know the name of the auditor. THe absolute worst thing that can happen is say No we can't share that info. at best you might get some kind of a clue as to where the problem lies.
