Admit I didn't grasp the answer at first, so it probably doesn't have a global answer. I'd expect it's protected by corporate interests in the US, but perhaps in places like India, more lenient to the public by the Right to Information Act?
In any case, if more of us were like Vod in demanding to see proof of insurance before joining a business, they'd be less scams happening. Reminding myself I'm invested in a few businesses I don't have full (or any) guarantees in... I wonder if proof of insurance could still retain privacy.
Vod's take on the issue is asking for personal insurance documents of the people involved in the business - typically that is something that's considered 'private info'.
If it were business insurance or auto insurance - then it'd be a different story because the information there is accessible to regulatory bodies and therefore to the public.
Yes - ask for insurance - but all I am saying is - don't be alarmed if the person you're asking isn't too enthusiastic about sharing that info - considering how that can be seen as a breach of privacy.
This can certainly be one yardstick for measurement - but not the only move at an investor's disposal.
