	DIRECTIONS
(1)	If there are a number of substantial holders with similar or related interests (eg. a corporation and its related corporations, or the
	manager and
	trustee of an equity trust), the names could be included in an annexure to the form. If the relevant interests of a group of persons are
	essentially
	similar, they may be referred to throughout the form as a specifically named group if the membership of each group, with the names
	and addresses
	of members is clearly set out in paragraph 7 of the form.
(2)	See the definition of “associate” in section 9 of the Corporations Act 2001.
(3)	See the definition of “relevant interest” in sections 608 and 671B(7) of the Corporations Act 2001.
(4)	The voting shares of a company constitute one class unless divided into separate classes.
(5)	The total number of votes attached to all the voting shares in the company or voting interests in the scheme (if any) that the person
	or an
	Associate has a relevant interest in.
(6)	The person’s votes divided by the total votes in the body corporate or scheme multiplied by 100.
(7)	Include details of:
	(a)any relevant agreement or other circumstances by which the relevant interest was acquired. If subsection 671B(4) applies, a
	copy of
	any document setting out the terms of any relevant agreement, and a statement by the person giving full and accurate
	details of any contract,
	scheme or arrangement, must accompany this form, together with a written statement certifying this contract, scheme or
	arrangement; and
	(b)any qualification of the power of a person to exercise, control the exercise of, or influence the exercise of, the voting powers
	or disposal of the
	securities to which the relevant interest relates (indicating clearly the particular securities to which the qualification applies).
	See the definition of “relevant agreement” in section 9 of the Corporations Act 2001.
(8)	If the substantial holder is unable to determine the identity of the person (eg. if the relevant interest arises because of an option) write
	“unknown”.
(9)	Details of the consideration must include any and all benefits, moneys and other, that any person from whom a relevant interest has
	acquired has, or
	may, become entitled to receive in relation to that acquisition. Details must be included even if the benefit is conditional on the
	happening or not of a
	contingency. Details must be included of any benefit paid on behalf of the substantial holder of its associate in relation to the
	acquisitions, even if they are not paid directly to the person from whom the relevant interest was acquired.
