NatWest Group PLC said Thursday that it has pleaded guilty to breaches of money-laundering regulations and warned of booking a provision in its third-quarter results in relation to a potential fine.

The U.K. bank said that it failed to comply with Financial Conduct Authority regulations from 2012 to 2016, acknowledging that it didn't monitor the accounts of a U.K. incorporated customer as it should have.

The FTSE 100 company said that it has cooperated fully with the FCA since it opened the investigation, adding that the U.K. regulator has confirmed it won't take action against any current or former employees of NatWest.

The case has been remitted to the Crown Court for sentencing, which will be determined at a hearing expected to take place in four-to-eight weeks time, it added.

NatWest said a provision will be made in its third-quarter financial accounts in anticipation of a potential fine.

"We deeply regret that NatWest failed to adequately monitor and therefore prevent money laundering by one of our customers between 2012 and 2016. NatWest has a vital part to play in detecting and preventing financial crime and we take extremely seriously our responsibility to prevent money laundering by third parties," NatWest Chief Executive Alison Rose said.
