1. Increases/Decreases of Capital.

If the issuer undertakes any change to the securities issued in any of the methods specified above, the issuer must inform the SDC in writing at least ten (10) days before the action date to make the changes required, specifying the corporate action, the date of the register's closure and the effective date. The SDC will make the required changes to the deposited securities whether registered in the investors’ accounts at the SDC or the investors’ accounts under the jurisdiction of any of its members. The SDC provides the issuer with the Shareholders’ Register containing the names of securities owners, the number of securities owned by each owner and any details required by the issuer as of the date of the register's closure.

A public shareholding company should inform the SDC of the date of its general assembly meeting at least fifteen (15) days before the meeting via a written letter specifying the date of the meeting and the date of the register's closure. The SDC in turn provides the issuer with the Shareholders’ Register of deposited securities on the date specified by the issuer.
