About American Depositary Receipts (ADRs)
An ADR is a negotiable certificate that represents ownership in securities of a
non U.S. company. ADRs are issued by a sponsoring U.S. bank and denominated in
U.S. dollars. An ADR represents a specified number of shares (or one share) in
a foreign stock that is traded on a U.S. exchange.

ADRs allow foreign companies shares to be traded in a similar manner to shares
in U.S. companies on the New York Stock Exchange (NYSE), the American Stock
Exchange (AMEX), NASDAQ and the over-the-counter (OTC) market. ADRs enable U.S.
citizens to acquire shares in a foreign company without the need for cross
border or cross currency transactions. Any dividends and capital gains are in
U.S. dollars.
