What is an 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.

ADRs were specifically designed to facilitate trading of non-U.S. securities by U.S. investors. ADRs trade, clear, and settle in accordance with U.S. market regulations and permit prompt dividend payments and corporate action notification. If an ADR is exchange-listed, investors also benefit from readily available price and trading information.
