Only those who have directly entered into a financial interest agreement in their own name with the local telephone company are entitled to shareholder rights.
The change of ownership of the telephone line does not necessarily grant the buyer rights over shares, given that they are different assets. Shareholder rights originate from the financial interest the promising subscriber acquired from the telephone company. As not all telephone lines were purchased under a financial interest agreement, telephone lines do not necessarily confer rights to shares.
Please note that the transfer of shares is only carried out with the express authorization of the shareholder, either directly at the depository institution or through a public power of attorney.
To find out if you still have shares, you should make an inquiry at any Banco do Brasil branch upon presentation of personal documents and proof of residence.
