with respect as fellow long...
Debt cannot be "cleared."
Debt can be paid, settled, or discharged.
In this case (in DD first provided by m0n), Exhibit D pp 18:
CANCELLATION OF SECURITY REGISTRATIONS
the shares issued to; Bridging Finance Inc; HSBC Bank Canada; and Comerica Bank et al, were all cancelled.
NO OTHER SHARES OR SHARE CLASSES WERE CANCELLED. Nor, were other (common) shares mentioned anywhere. This means, for the purposes of the Visolis transaction, those shares HAD VALUE and the rights were surrendered by the holders (obviously for payment). IMO, that means commons HAVE VALUE.
I can only assume these entities surrendered their collateral because their loans are paid in full, via the Visolis transaction. Those shares were then cancelled.
Enjoy! :-)
