Applications can only be made by giving IBHK electronic instructions via Client Portal, to act as your agent and cause HKSCC Nominees, or any other Nominee Companies instructed by Interactive Brokers Hong Kong, to make an application on your behalf. Any successfully allocated shares will be allocated in the name of the common nominee and deposited in IBHK's HKSCC account making them available to you in your IBHK account on the listing date.
If you would like to make a paper based application please refer to the "How to Apply for Public Offer Shares" section of the listing company's prospectus for details.
