Bonderman converted to commons in order to help WMI (not WMB or fsb like some suggest), I repeat, to help WMI sell itself.
I suggest you familiarize yourself with what assets were part of the bank, because the Providian Bank/Card business now belong to JPM and those assets were indeed part of WMB, now JPM.
JPM got everything they wanted, and they will not be buying WMI.
Killinger should have sold when he had the chance.
