If you see a dividend reflected on your recent account Activity that displays a negative dollar value, what you are seeing is an American Depositary Receipt (ADR) fee.
ADRs allow US investors to invest in foreign securities. When you own an ADR, a custodian is in charge of holding the ADR and maintaining the records. The custodian collects the dividends paid out the foreign issuer, converts it into US dollars and deposits into your account. The custodian charges a fee for all these services and this fee is called the ADR fee.
