The HCU is unsecured sub debt and an SPV trust preferred.
The HCQ is a Corporate.
Could HCU be related to CTs? They have a different expiry.
Are the bond tranches $1B each? No share amounts are given but it's a guess.
The most deceiving statements on the POR are about "Satisfied in Full" or "Paid in Full"; if the debt is carried, face value does not have to be paid until maturity or they are called.
It is the excuse to loot and abscond with guarantees while trading the CTs for the NOL requirement.
