If something gets foreclosed on the assets go to a receiver, the shares would be worthless so I don't think that is who's buying. Hasn't been enough shares to get excited about anyways. Getting control of the shell does have some value though, as tarnished as it will be.
Opinions posted by me are just that, my opinion. This is in no way a suggestion to buy or sell any security. Consult your own financial advisors for investment advice.
