Holdco did not pay all of the $ 5.2 B in Cash/Securities to SHC. Much of the $ 5.2 B Sale was a cancellation of DEBT and the assumption of certain LIABILITIES that were on SHC’s balance sheet.
The SHLDQ equity interests are in the Assets of SHC. If Holdco receives some or all of the NOLs, that could cancel out some or all of the Cash/Securities SHC received from the Sale.
