Most large commercial banks have brokers authorized to operate in the financial market. However, by regulatory determination, the broker is a legally separate entity from the bank. When you “trade shares through a bank,” you are actually trading through the bank’s broker. The rules that apply to these brokers are the same as the others.

Custody is the custody (and related services) of bonds, securities and financial assets, such as stocks, for example. The custodian registers the shares in the name of those who bought them, guaranteeing their ownership. Petrobras ‘shares may be held in custody directly at Banco Bradesco, Petrobras’ primary custodian or in the Brazilian Liquidation and Custody Company (CBLC), when the investment is made through a securities broker.

Generally, shares are traded according to a standard lot, in quantities fixed by the stock exchange. In the case of Petrobras, the standard lot is 100 shares. There is, however, the possibility of trading fewer shares than the standard lot, in the so-called fractional market, where the codes of Petrobras shares are PETR3F and PETR4F.

Banco Bradesco, which is the managing agent of Petrobras’ share system, sends the statement of its shareholding position to the shareholder address, when shares are moved, when dividends are paid and for income tax purposes. For this reason, it is essential that the shareholder update his address at any branch of Bradesco. In addition, the shareholder may, at any time, attend a branch of Banco Bradesco and request an extract of its shareholding position in Petrobras.

Petrobras has minimum mandatory dividends corresponding to 25% of the Adjusted Net Income. In addition, preferred shares are entitled to a minimum dividend of 5% (five percent) calculated on the share of capital represented by this type of shares, or 3% (three percent) of the share’s equity value – the largest always prevails.

In addition, the Company’s Shareholder Remuneration Policy provides that when the gross indebtedness, including commitments related to leasing, exceeds US $ 60 billion, the Company may distribute to its shareholders the minimum mandatory dividends provided for by law and in the Bylaws, mentioned above.

When the gross indebtedness, including commitments related to leasing, is less than US $ 60 billion, the Company may distribute to its shareholders 60% of the difference between operating cash flow and investments: Remuneration = 60% x (FCO – CAPEX). In this formula, the following are not considered as CAPEX: (a) the proceeds from the sale of assets; (b) payments for participation in the bidding rounds for oil and natural gas exploration and production; and (c) payments related to the acquisition of companies or equity interests.

Petrobras may also, in exceptional cases, make the payment of extraordinary dividends, exceeding the annual amount established above.

Preferred shares will participate, not cumulatively, on equal terms with common shares, in the distribution of dividends, when higher than the minimum percentage guaranteed to them.

Important: In order for the Petrobras shareholder to receive the dividends to which he is entitled, it is essential that he keep his registration data updated, informing Banco Bradesco or its securities broker any change of address or bank account for credit of dividends.

We also remind you that, according to the Brazilian Corporate Law, dividends expire in three years from the date on which they were made available to the shareholder.

For those shareholders whose shares are held in custody directly at Banco Bradesco, dividends and interest on equity will be deposited directly into their checking account. If you have not received your dividends, your current account data is likely to be out of date. To update them, just look for any branch of Banco Bradesco, in possession of your personal documents.

Shareholders who have their investments in a securities broker will receive in their account with that institution.
