See response from Pitcher Partners regarding shares being removed from my holdings on Comsec:
I advise that as trading in KAB has been suspended for 60 business days, the ASX has revoked approval of these securities with the effect of transferring them from the CHESS sub register to the issuer’s sub register. In this regard, as a shareholder you are unable to view your shares on your trading platform.
This is standard procedure and the shares are still yours, you are just unable to deal with them at this stage. You may wish to refer to the below guide issued by ASIC for further information regarding insolvency and how it affects shareholders.
