Ann: Boral to return $3 billion to shareholders, page-16

"For shareholders who hold their shares on capital account for Australian income tax purposes, the cost base
(and reduced cost base) of each share will be reduced by $2.65 per share for the purposes of calculating any
capital gain or loss on the ultimate disposal of that share for Australian income tax purposes. An immediate
capital gain would arise for shareholders where their cost base of any share is less than $2.65."

Does this mean that instead of a $2.65 distribution the purchase price will be changed by deducting $2.65 from the initial purchase price? That's what I got from it, a little confusing and hope some of you here with more knowledge than I may be able to shed some light on this. Thanks
