What is the “Over the Counter” market? Sponsored Level I ADRs are traded in the US Over the Counter (OTC) market with prices published in the "Pink Sheets". Establishment of a Sponsored Level I program does not require full SEC registration and the company does not have to report its accounts under US GAAP or provide full SEC disclosure. Essentially, a Sponsored Level I Depositary Receipt program allows companies to enjoy the benefits of a publicly traded security without changing its current reporting process. What is the difference between an ADR and an ADS? An ADR (American Depositary Receipt) is a negotiable certificate issued by a depositary bank representing a specific number of shares of a non-US company quoted and traded in US dollars in the US securities market. An ADS (American Depositary Share) is the share issued under the ADR agreement which is actually traded. In many cases the terms ADR and ADS are used interchangeably. Who is the depositary bank for TGS ADRs? The Bank of New York Mellon (BNYM). The depositary bank plays a key role in the process of issuance and cancellation of ADRs. It also maintains the ADR holder register and distributes the dividends in U.S. dollars. The Bank of New York Mellon is a DTC (Depositary Trust Company) participant as are brokers and dealers, other banks, trust companies and clearing houses.

Yes, you can buy TGS ADRs through a broker or investment advisor. How do I convert my ordinary shares into ADRs? Converting ordinary shares into ADRs must be done through a broker or an investment advisor. Can I purchase ADRs directly from TGS? No. 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 the record. A beneficial holder is one whose holdings are registered in a name other than his or her own, such as the name of a broker, bank or nominee. I did not receive a certificate with the purchase of my ADRs. How can I obtain a certificate? For registered owners, ownership is registered by the depositary bank and is evidenced by an account statement, provided by the depositary. Registered owners may request a physical certificate issued by the Depositary Bank and receive dividends, and proxy materials directly from The Bank of New York Mellon. To have a physical certificate issued, complete, sign and return the tear-off portion of the account statement or contact The Bank of New York Mellon as indicated above. Owners of TGS ADRs that are registered in the "nominee name" or "street name" of a bank, broker or other institution that holds such securities for the accounts of others are considered beneficial owners. ADRs held in this form are book-entry securities, where the beneficial owner’s interest is recorded in an account held by the institution rather than by registration with the ADR depositary. Major benefits of book-entry ownership are the elimination of problems associated with paper certificates such as storage, safety of securities or cost and inconvenience of replacement. Book-entry ADRs eliminate the requirement for physical movement of certificates at the time of sale or transfer of ownership. Investors purchasing ADRs through a broker who wish to become registered owners must specifically direct the broker to register the shares with the ADR depositary. If you choose to have a certificate issued, please contact The Bank of New York Mellon. What does the term “Direct Registration Receipts” mean? The term "Direct Registration Receipts" means ADRs not evidenced by Receipts that are evidenced by book entry notations recorded on the Direct Registration System and by periodic statements from the Depositary. How can I find out how many ADRs I have? Contact The Bank of New York Mellon as indicated above or for those holders who are not registered because their shares are held through a nominee account, please contact your nominee for information on your ADR holdings. What should I do if I lose an ADR certificate? If your certificate is lost, stolen, or destroyed, notify The Bank of New York Mellon investor hotline +1 888 737 2377. Please ensure you have your Social Security Taxpayer Identification number ready when calling. How do I register a change of address? It is important that you call The Bank of New York Mellon when you move so that your account records can be updated and your dividend check is sent to the right address. How are dividends paid? Dividends are paid in U.S. dollars, just like dividends on US shares. How can I replace a lost dividend check?
