The shares are dead due to the liquidations outcome. They do not need to be canceled as the company was liquidated, sold off all assets and was shut down years ago. Let’s not forget its nameless voided debt ridden shell too. Makes no difference that the CUSIP was suspended as the shares are attached to a dead shell with 100 mil of debt attached to it
The CUSIP was suspended and the ticker deleted. They will never trade again. The issuer, BioAmber, Inc., had its corporate charter revoked by the state, so it isn't even a company on paper anymore and for years.
"Cancelled" is a distinction without a difference.
