WMIIC: WMIH owns the shell, and the releasing shareholders own the filling. If there had been anything left in WMIIC when it was dissolved, which I doubt, it wold have gone to the LT. But - as I said - I doubt there was anything left.
And WMIH was hardly an empty shell. It had $5.8 billion in NOLs that were enough to attract NSM to do the deal. Imagine the price advantage those NOLs provide. They allow the merged company to penetrate new markets.
