fwh, my brother has TD Ameritrade also and I looked at his account and I received the same information as you regarding GE. Other than a technology malfunction, I have no idea.
Now you do know that GE is selling to Blackstone billions in real estate holdings and stranger things have happened or dare I let the mind wonder here?
We know thing for sure and that is to use 6 billion in tax attributes and IMHO, really more like 10 to 25 billion in total tax attributes, then WMIH would have to be the purchaser of a very large company if they were only buying one company in the near future.
