Tax benefit recognized on the outside basis differences for investment in subsidiaries and affiliates
during the year ended March 31, 2021 of approximately ¥21 billion (which decreased Nomura’s effective tax rate by 9.1%) arises from the recognition of deferred tax assets from the decision and commitment of Nomura management to liquidate a certain wholly-owned subsidiary within Nomura in the foreseeable future.
