IPO - QEM Limited, page-20

Can I ask you, when you applying for IPO not via internet portals like OM and RB, which transferring your allocation to your existing HIN, but via brokers like Hartley, Shaw etc, are you keeping your new allocation with them or doing transfer to other brokers account like Commsecure, Nabtrade etc? Or you initially providing them with your preferred broker's account and allocation going directly to this account?
I am asking, because I am not very comfortable to keep my shares in a lot of different places under different HIN.
But somebody told me, that if I will not keep allocation with small company, who help me initially to get IPO allocation, next time they will not counted me as a client for popular IPOs, because it's not very profitable for them ,. They would like to make money in a future from your shares and pushing you to keep shares with them. I even heard that your adviser can reject continue to work with you, if you not happy to keep your stock with them.
Can you comment, please.
