An employee leaked sensitive market information.
The FSA found significant inadequacies at Nomura Holdings and Nomura Securities, including inadequate information control systems and insufficient improvement of operations based on past administrative actions.
Nomura announced measures, including temporarily cutting the pay of Nagai and other executives, to prevent a recurrence of such incidents.
