The ownership could be stated as WMI on paper but since safe harbor assets were bankruptcy remote there is a possibility that it might not be covered by POR7.
Do you want to take a risk by sitting on our ass hoping that it will come back to us automatically? What if we need to claim it to get it back. There is a risk it might go "unclaimed" when the asset comes out of safe harbor because the "owner" WMI is considered deceased.
I'm not saying this is a fact. I'm just saying I'm not a legal expert and this could be similar to a person dying without a will -- where next of kin may have to file a claim or the assets might go unclaimed and return to state.
