wowalters, unfortunately that is a misunderstanding. The confusion comes from the early WMIH industry code having it listed as a 'Federally Chartered Bank' -- that was a carry-forward of the former WMI classification. But just having a database error (or hadn't been updated) is far from actually having a charter.
The reality is, upon seizure by the OTS, WMI lost it's banking charter - as, obviously, the bank was seized. More recent 'industry code' updates have WMIH as an 'Insurance Company' categorization (which, at the moment, that's what it's sole operating business WMMRC) is. The corrective update has been made. And now it should be clear.
