Revenue recognition

On April 1, 2018, Nomura adopted Accounting Standards Update 2014-09 “Revenue from Contracts with Customers” and replaced existing revenue recognition guidance with a new prescriptive model. As a result of this adoption based on the modified retrospective application, the beginning balance of Retained earnings has been adjusted.

Changes of offsetting of derivatives

Nomura collects and remits cash margin between its clients and central clearing houses in its execution and clearing services of exchange-traded derivative transactions. Cash margin collected from clients and remitted to central clearing houses was reflected on Nomura’s consolidated balance sheets. However, with effect from April 1, 2018, revisiting nature of the transactions, Nomura has revised its accounting policy for when such balances are recognized on Nomura’s consolidated group balance sheet and as a result, certain cash margin amounts held on behalf of clients as well as an equivalent amount reflecting the obligation to return such amounts to clients are no longer recognized on the balance sheet if certain criteria are met. Nomura has restated previously reported amounts of Receivables from other than customers decreased by 237.0 billion yen and Payables to other than customers decreased by 237.0 billion yen, respectively, to conform to the current presentation.

Daily variation margin for certain derivative transactions traded in Japan was reflected on Nomura’s consolidated balance sheets. However, from April 1, 2018, Nomura changed its accounting policy as a result of amendment of the rules of a specific central clearing house and daily variation margin is now off-balanced. Nomura has restated previously report amounts of Trading assets decreased by 4.9 billion yen, Receivables from other than customers decreased by 5.5 billion yen and Trading liabilities decreased by 10.4 billion yen respectively to conform to the current presentation.

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 25, 2018) and Form 20-F (the annual report filed with the U.S. Securities and Exchange Commission on June 25, 2018) for the year ended March 31, 2018.
