On 4 September 2018 ING announced that it entered into a settlement agreement with the Dutch Public Prosecution Service (DPPS) relating to previously disclosed investigations regarding various requirements for client on-boarding and the prevention of money laundering and corrupt practices.

As previously noted, in connection with the investigations ING also received information requests from the US Securities and Exchange Commission (SEC). ING has received a formal notification from the SEC that it has concluded its investigation. In the letter the Division of Enforcement states that, based on information as of this date, it does not intend to recommend an SEC enforcement action against ING.
