I imagine they (along with most sensible holders) must be pretty desperate to get out before the SP plummets. An unfortunate issue is that they will avoid making any concerns they have public because it would make exiting the company impossible. I know if I was in this company at a 50% loss atm, I would sell and be happy to walk away with half my money.
For the record, I haven't held shares since back in the ETC days of 2004, and have followed ETC/NBS as a middle ages housewife follows Days of Our Lives ;)
