Correction 27.5m partly paid shares. 20c to pay. They got a world of pain coming.
The question remains when?

Companies can also choose to offer shares where only a portion of the face value of the share is payable up-front. These are known as partly paid or contributing shares. For example, let's say Company XYZ sells shares for $50. If the company has received $50, it becomes a fully paid share, but if less than $50 has been collected, it is a partly paid share.
The company may set a date for the remaining payment or can opt to inform shareholders of the "call-up" date when it needs the funds. Owners of these shares are legally obligated to pay the balance when the company requests it. When these monies are received by the company, the partly paid shares become ordinary fully paid shares.
