Ann: Information Required Under ASX LR 3.10.5A-CAZ.AX, page-2

Maybe I missed it but under ASX Listing Rule 3.10.5A - point B where the equity is issued for cash, provide a statement as to why do the placement under rule 7.1A and not as a pro rata issue or other type of issue which existing ordinary security holders would have been eligible to participate?
They seem to just give a reason for what the funds will be used for. Does anyone know reason for not giving existing shareholders a look here instead of diluting the holdings a further 16%. Already duilted 5% late december with the 6.8mln share placement.
