Ng will be required upon returning to the US to begin his prison term, prosecutors said in an earlier letter to the judge.

Roger Ng was convicted in March 2022 on bribery and money laundering conspiracy charges.

Ng is permanently banned from performing any regulated activity under the Securities and Futures Act.

The judge says Ng 'played a role in one of the largest financial crimes of all time'.

A forfeiture amount will be determined later, the Department of Justice says.

Ng spent six months in a Malaysian prison before waiving his right to contest extradition to the US in 2018.

Roger Ng's lawyers ask the court to show mercy and to sentence him to the prison time he has already served in Malaysia.

The prosecution says this is to avoid any waste of time although it is still open to pursuing the case in the future.

Ng is accusing Leissner of repeatedly lying in order to steal his investments in energy drink maker Celsius Holdings and artificial intelligence company Sentient Technologies.

The Kuala Lumpur High Court says the case should not be on hold for too long.

Case mention will now be heard on Oct 19 given that his sentencing in the US is scheduled on Sept 13.

The jury convicted Ng of two counts of conspiracy to violate the Foreign Corrupt Practices Act and one count of conspiracy to commit money laundering.
