The share issued under an American Depositary Receipt agreement which is actually traded.
Represent the ADR and it is ADS that is actually traded. These two terms are often interchanged but technically it is the ADS that is traded. See also 'ADR' definition above.
Similar to an American Depositary Receipt, but the issuance is sponsored by the foreign company that issued the common stock, rather than the bank that holds the share on deposit.
