American Depositary Receipt (ADR)

What is an American Depositary Receipt (ADR)?

An ADR is a negotiable U.S. certificate representing ownership of shares in a non-U.S. corporation. ADRs are quoted and traded in U.S. dollars in the U.S. securities market. Also, the dividends are paid to investor in U.S.dollars. ADRs were specifically designed to facilitate the purchase, holding and sale of non-U.S. securities by U.S. investor, and to provide a corporate finance vehicle for non-U.S. companies.


What are the benefits of ADRs to US investors?

US investors generally prefer to purchase ADRs rather than ordinary shares in the issuer’s home market because ADRs trade, clear and settle according to US market conventions. One of ADRs’ main advantages is the facilitation of diversification into foreign securities. ADRs also allow easy comparison to securities of similar companies as well as access to price and trading information, if listed. ADR holders also appreciate dollar dividend payments and receiving corporate action notifications.

What is the difference between a Registered holder and a Beneficial ADR holder?

A registered holder is one whose name appears on the books of the depositary. The registered holder is considered the owner of record. A beneficial holder is one whose holdings are registered in a name other than their own, such as in the name of a broker, bank or nominee.


How are ADR dividends paid and taxed?

Dividends are paid in U.S. dollars and are generally taxable, just like dividends on U.S. shares. In addition, taxes may be withheld by the ADR company's local government. Depending on individual circumstances, foreign taxes withheld might be applied as a credit against U.S. taxes, or tax reclaim opportunities may be offered. Please contact BNY Mellon to learn more.

How can I convert ordinary shares in CGG into CGG ADRs?

A shareholder wishing to convert Paris Stock Exchange-listed ordinary shares in to ADRs should, in the first instance, request that their broker contact the ADR Broker Desk at The Bank of New York Mellon. Contact details can be found below:

Alternatively, the shareholder may contact the ADR Broker Desk at BNY Mellon directly.

  1. When contacting the ADR Broker Desk, the broker will be asked to confirm the following information:
    • the number of ordinary shares the shareholder wishes to convert into ADRs (based on the current ratio of 1 ordinary share equal to 1 ADR);
    • the custodian name, account name and account number of the account in France from which the ordinary shares will be delivered;
    • the number of the DTC account in the US to which the shareholder wishes their ADRs to be credited. If the shareholder does not have a DTC account, they will need to appoint a nominee (e.g. a broker) to hold the ADRs on their behalf.
  2. Once these details have been confirmed, the broker (or shareholder) should instruct the delivery of the ordinary shares from their custody account in France.
  3. On the day that the local custodian confirms to BNY Mellon that the ordinary shares have settled in BNY Mellon’s account, BNY Mellon will instruct the delivery of the equivalent amount of ADRs to the requested DTC account.
  4. A fee per ADR issued is payable to BNY Mellon upon the delivery of the ADRs. Most commonly, when BNY Mellon delivers the ADRs to the specified DTC account, this is done on a delivery versus payment (DVP) instruction against the conversion fee. If an alternative method of payment is required, please contact the ADR Broker Desk for further details. Where the DTC account is operated by a broker on behalf of a shareholder, the broker should confirm to the shareholder that it has received the ADRs and is holding them on his/her behalf.
