It's good that at least one poster is looking for factual information. The timely disclosure of interests held by directors and substantial shareholders is important to investors :
Failure to Lodge Forms
Under section 671C a person who contravenes the Substantial Shareholder
obligations and/or notice requirements may be liable for any loss or damage caused
to another party, but they may have a defence if the contravention was due to:
- inadvertence or mistake
- being unaware of a relevant fact or occurrence.
NOTE: these obligations lie with the Substantial Shareholder – there is no obligation
on the Company to ensure a Form is lodged nor any ramifications for the Company if
it is not lodged. However, a Company may offer to ‘assist’ the Substantial
Shareholder’s stock exchange lodgement requirement by offering to lodge on his
behalf through the Company’s on-line lodgement facility.
