I have referenced this already. The value you are looking at in your account is nothing more than the limbo we find ourselves in waiting for the liquidation to complete. The shares have in fact been deleted, this is not disputable. You can't sell them, you can't trade them, you can't get certificates for them - because they do not exist.
What is disputable is whether or not the previously existing shares will have liquidity value upon the total liquidation of Humanigens assets in the process of paying off creditors.
