A few things go in to it and I don't know the in an outs but bigger players ie Super funds/Financial institutions get a better crack at it. Less administration but also they will remember each other in the next float especially if it goes well, it how business works you scratch my back i scratch yours.

The fall of Latitude Financial was partially due to lack of institutional support. How much money you have with the broker , the amount of trades must also play a part. One thing that wont really matter is the date you expressed interest in participating in the IPO. They will look after their bigger and more profitable clients that is just life.
