Ann: Share Purchase Plan Offer Booklet, page-59

Just checked… there are about 11,000 Paladin shareholders. If every shareholder were to apply for the full $30k, that would raise $330m. The planned $15m is 4.5% of this amount.

if we assume that one third of shareholders apply (on average) for one third of the $30k max, then the total applied for would be $37m, implying a 58% scaleback, assuming the $15m is not increased. Shareholders with larger holdings may get their full application, while those with smaller holdings will have a bigger scaleback. Obviously these numbers change with different assumptions, eg if half of shareholders apply for half the max, the on average the scaleback would be 82% to hit $15m.

As @graymatter pointed out… maths!
