Ann: Change in substantial holding, page-4

These requirements apply when the votes attached to securities, in which a

person and any of their associates have a relevant interest (as a proportion of

all voting shares or interests), increase above one of the following two

thresholds:

(a) the 5% substantial holding threshold—after which a person must

provide substantial holding notices relating to movements above or

below the threshold, and any change of 1% or more (Pt 6C.1); and

(b) the 20% takeover threshold—after which acquisitions and offers to

acquire relevant interests in voting shares or interests are only permitted

through certain transactions or in certain circumstances (Ch 6).
