Issuer Sponsored holders are allocated two unique identification numbers – an SRN and a Holder Number. The SRN provides a higher level of security (similar to a credit card PIN); it is only shown on Issuer statements and must be provided to your broker when buying or selling CSR shares. The unique holder number is quoted on other correspondence and cannot be used to sell your holding in CSR. You can request your SRN by contacting the share registry by letter or fax. You must provide the following information: Full name(s) and address (old and new if changed) of the registered investor(s) Company/Trust in which the investments are held Number of shares/units held Signatures of the registered security holders: You may also obtain your SRN in person from the share registry upon production of a drivers licence or current passport.
