I sincerely hope you're not trying to enlighten me with your comprehension skills.
The "certain assets" have already been clearly defined.
Also clearly defined, your shares remain with Delaware 4612067, you remember what that is, yes?
That is the former company that used to (past tense) own & carry out business under the trade name BioAmber.
That trade name was sold as part of those "certain assets" (All assets) along with the intangibles, IP and everything else.
Also clearly defined, the former company no longer has an exchange listing, or ticker & has had it's cusip identifier suspended due to bankruptcy liquidation.
I would imagine that causes a few "complications" for former shareholders expecting a payout.🤔
With all due respect, ignoring the secured creditors were left impaired at the completion of the liquidation process to the tune of +$101,000,000 plus in outstanding money owed.
