how much can you invest?, page-9

I may be wrong here but in my understanding we have two separate beasts being confused.
Firstly we had a "non-renounceable rights issue".
Now we have a "share purchase plan" (spp).
Both are different.
I believe that what the guide is referring to is that if there were to be another spp within 12 months of this one or if there had been a previous spp less than 12 months ago then you would only be entitled to a maximum of 15k worth of shares.
The shares purchased on the "rights issue", as I understand it, do not come into the equation.
I may be barking up the wrong tree so do you own research.

Good luck and good buying.
