It looks like the receivers office is the government arm that oversees trustee activities. My first thought was possibly that of Porters as well - with Jimmie gone the licence to practice has been revoked or halted. After reading a bit more though, it seems like it could be something totally different such as:

Regulatory Investigation
Fraud or Misconduct Investigation
Insolvency Proceedings

Not sure which of these or something else would be the lesser evil/least damaging if any. I'm thinking not fraud or misconduct because wouldn't CI1 pause or notify the market before going to the receivers office? I think insolvency proceedings is unlikely as CI1 has the cash.

Pure speculation I guess until we see the letter.

DYOR. My opinion only.
