Hi, how do I subscribe for SIA’s rights issue if my SIA shares are held in a Standard Chartered Custodian Account and not a CDP account?

Standchart will either send you a letter or an sms with the information. You will have to call them and tell them your instructions.

Do note that oversubscription request is not confirmed and may not be fulfilled subject to the company decision. Only your entitlement is confirmed.

This was the process for one of my stocks when there was a rights issue.
