In accordance with Article 46 of the Federal Law "On Joint-Stock Companies," the rights to shares are confirmed through issuance of an extract from the register of company shareholders.
To obtain information about the number of RusHydro shares you hold, we recommend that you contact the Company Registrar (VTB Registrar JSC)  to receive an extract from the Shareholder Register.
The cost of one extract from the Shareholder Register is:
If your shares are stored in a depository, you need to contact it to get a securities account statement.
The absence of a shareholder's correct personal information with the Company, its Registrar, or the Depository (if shares are kept in a securities account) is the main reason why a shareholder does not receive dividends and voting ballots.
To update your details, you need to update your Questionnaire of a Registered Person. To do this, you must submit a request at the place where your shares are stored (Registrar or Depository).
If your shares are stored in the RusHydro Shareholder Register, you can familiarize yourself with the list of documents required for updating the Questionnaire from the Registrar's website at https://www.vtbreg.com/shareholder/operations/operations-109/.
Please note that you cannot simply submit copies of documents to RusHydro to update your Questionnaire. You must submit such documents to the Registrar or your Depository in person or through your authorized representative.
The Registrar or the Depository (if your shares are stored in the securities account) probably do not have your correct contact or bank details.
Please see the answer to Question 2 to learn how to update your Questionnaire.
