Have shares left in your account?
Then the company has not sold. In order to buy the company, they'd have to buy the shares. Plus, the monitor has been clear that only the assets were sold in the liquidation, and there are no transactions that have occurred or are occurring involving the shares.
No matter now many times these irrelevant snippets of documents are posted up, the whole story is that, after the asset liquidation, BioAmber is an empty shell with no operations and no income to even put a dent in its massive debt. All that anybody has to do is read the whole of the 10th and 11th monitor's reports (the latest status of the proceedings and the financial state of the company) to conclude this company will no longer exist at the conclusion of the bankruptcy proceedings.
Companies that are in bankruptcy proceedings with large debt and no sources of income don't survive. Ever.
