What is an American Depositary Receipt (ADR)?

Depositary receipts (DRs) are negotiable U.S. securities issued by a U.S. bank, referred to as a “depositary bank,” that typically represent a non-U.S. company’s equity. DRs trade freely in global markets and can be listed on major stock exchanges including NASDAQ.

DRs facilitate cross-border trading and may help non-U.S. companies raise capital in global equity offerings or be used as acquisition currency for mergers and acquisitions. DRs allow non-U.S. companies to make their shares available outside their home markets and allow investors in the U.S. and elsewhere to easily invest in companies on a more global basis.
