Nomura Holdings Inc. has recently updated its risk disclosures in a regulatory filing in the US. This update was made in response to the arrest of a former employee in Japan who is facing serious charges, including robbery, arson, and attempted murder.

The company's 6-K report submitted to the US Securities and Exchange Commission now includes the potential risk of employees or others engaging in "criminal or other unlawful actions against customers or their families." Alongside this addition, Nomura also includes its standard warnings about business misconduct and the improper use of information.

This incident has raised concerns about employee conduct and the potential impact it could have on the firm's reputation and operations in the financial sector.
