Under the wikipedia topic of Insurance in general, theres a few interesting things that may apply to this case. I haven't really followed this, as I haven't invested in anyone, but I know the jist. Feel free to read through the link, but heres a few things that caught my attention.
http://en.wikipedia.org/wiki/Insurance"Utmost good faith – the insured and the insurer are bound by a good faith bond of honesty and fairness.
Material facts must be disclosed."
if the fact that he was investing in Pirate was not disclosed, that goes against that aspect.
"Insurance scholars have typically used morale hazard to refer to the increased loss due to unintentional carelessness and moral hazard to refer to increased risk due to intentional carelessness or indifference. Insurers attempt to address carelessness through inspections, policy provisions requiring certain types of maintenance, and possible discounts for loss mitigation efforts."
"The policyholder may hire their own public adjuster to negotiate the settlement with the insurance company on their behalf."
Very Interesting here - "Business interruption insurance
covers the loss of income, and the expenses incurred, after a covered peril interrupts normal business operations."
What I did learn here though is, just by saying that the asset is insured, that by default gives it EVERY type of possible insurance (including those odd ones such as kidnap insurance, nuclear insurance, etc) as long as they are related to the business model HK had. So if you owe someone money, that you have tied up in your HK account, and you are kidnapped because of this, HK is liable for this as well, and by law are required to pay for any damages that may result. But either way, look into it yourselves, very interesting concepts.
Then again, how you would get this enforced is above me, but I'm just providing a bit of insight that you can interpret any way you like.
