The Group has an American Depositary Receipt (ADR) programme in the U.S., sponsored by Citibank. This helps to enhance the Company's corporate image and visibility in the U.S. and broaden its shareholder base.

An ADR is a form of negotiable certificate evidencing ownership of shares in a foreign company. They are attractive to U.S. investors because they are quoted and traded in U.S. dollars, and are governed by U.S. trading and settlement procedures. ADRs minimize the transaction cost to investors, thereby enhancing liquidity. The underlying shares which the ADRs represent remain on deposit in the issuer's home market.
