Go to the last earnings report and read the "about Ambec" section it will explain what happens to the existing shareholders of ABKFQ. In short the shares still trade under that symbol but once they come out of BK those shareholders will be canceled. It is in the report. The fraction of a penny traders will trade until that time but who ever is standing without a chair to sit in at the end of the musical chair tune will hold the bag of worthless stock. Those are the facts, unfortunately I have been there and done that, it never ends well.
