Recognition and measurement of financial assets and financial liabilities

On April 1, 2016, Nomura early adopted the presentation change of own credit adjustments provided by Accounting Standards Update 2016-01 “Recognition and Measurement of Financial Assets and Financial Liabilities.” Accordingly, unrealized changes in the fair value of financial liabilities elected for the fair value option attributable to instrument-specific credit risk (“own credit adjustments”) are now presented separately in other comprehensive income rather than through earnings. As a result of this adoption based on the modified retrospective application, the beginning balance of Retained earnings has been adjusted.

Consolidation analysis

On April 1, 2016, Nomura adopted Accounting Standard Update 2015-02 “Amendments to the Consolidation Analysis.” Accordingly, the consolidation guidance applied to certain investment companies, money market funds, qualifying real estate funds and similar entities has been changed. As a result of this adoption based on the modified retrospective application, the beginning balance of Noncontrolling interests has been adjusted.

Presentation of debt issuance costs

On April 1, 2016, Nomura adopted Accounting Standard Update 2015-03 “Simplifying the Presentation of Debt Issuance Costs.” Accordingly, debt issuance costs related to a recognized debt liability, which used to be presented as a separate asset, are now presented as a direct deduction from the carrying amount of that debt liability. These accounting changes have not had a material impact on Nomura’s consolidated financial statements.

The quarterly consolidated financial information herein has been prepared in accordance with Nomura’s accounting policies which are disclosed in the notes to the consolidated financial statements of Nomura Holdings, Inc.’s Annual Securities Report (the annual report filed in Japan on June 23, 2016) and Form 20-F (the annual report filed with the U.S. Securities and Exchange Commission on June 23, 2016) for the year ended March 31, 2016.
