"Zelko Lendich commenced in the role of an “interim general manager” on 23^rd April."

An extract from:

Sadly the controlling directors didn't see why they should advise shareholders of this appointment which is the most senior in the company. Optiscan Corporate Governance Policy includes:
"5.5 Types of Disclosure
Examples of formal releases of material information include announcements concerning significant contracts or major projects which will have a material effect on the price or value of company securities, joint ventures or changes in joint ventures, key management or Board changes, and acquisitions."

I point you to the words "changes in........key management".
