WMIIC was a "Guarantor" of the original "Financing Agreement" dated as of March 19, 2012 between WMI Holdings Corp and Owl Creek, Appaloosa, Centerbridge, Aurelius.
That "Financing Agreement" was terminated in January 2015, in lieu of the $600 million "Offering".
I have seen no filings that show WMIIC being a "Guarantor" for the $600 million "Offering".
