Accounting Policies [Abstract]

Description of business

Description of business—

Nomura Holdings, Inc. (“Company”) and its broker-dealer, banking and other financial services subsidiaries provide investment, financing and related services to individual, institutional and government clients on a global basis. The Company and other entities in which it has a controlling financial interest are collectively referred to as “Nomura” within these consolidated financial statements.

Nomura operates its business through various divisions based upon the nature of specific products and services, its main client base and its management structure. On April 1, 2021, the Asset Management Division and the Merchant Banking Division were combined and the Investment Management Division was established. Nomura reports operating results through three business segments: Retail, Investment Management, and Wholesale.

In its Retail segment, Nomura provides investment consultation services mainly to individual clients in Japan. In its Investment Management segment, Nomura mainly provides various investment management services such as establishing and managing investment trusts, discretionary investment services for domestic and overseas investors, investment and management for investment corporation and for funds for institutional investors, and management of Tokumei kumiai (silent partnerships). In its Wholesale segment, Nomura engages in the sales and trading of debt and equity securities, foreign exchange contracts and derivatives globally, and provides investment banking services such as the underwriting and distribution of debt and equity securities as well as mergers and acquisitions and financial advisory.

Basis of presentation

Basis of presentation—

The accounting and financial reporting policies of Nomura conform to accounting principles generally accepted in the United States (“U.S. GAAP”) as applicable to broker-dealers.

These consolidated financial statements include the financial statements of the Company and other entities in which it has a controlling financial interest. Nomura initially determines whether it has a controlling financial interest in an entity by evaluating whether the entity is a variable interest entity (“VIE”) under Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) 810 “Consolidation”. VIEs are entities in which equity investors do not have the characteristics of a controlling financial interest or which do not have sufficient equity at risk for the entities to finance their activities without additional subordinated financial support. Nomura consolidates VIEs where Nomura is the primary beneficiary, which is where (1) Nomura has power to direct the activities of the VIE that is most significantly impact the VIE’s economic performance; and (2) through Nomura’s interest in the VIE, the right to receive benefits or the obligation to absorb losses that could potentially be significant to the VIE, provided that Nomura is not acting as a fiduciary for other interest holders.

For entities other than VIEs, Nomura is generally determined to have a controlling financial interest in an entity when it owns a majority of the voting interests.

Equity investments in entities in which Nomura has significant influence over operating and financial decisions (generally defined as a holding of 20 to 50 percent of the voting stock of a corporate entity, or at least 3 percent of a limited partnership) are accounted for under the equity method of accounting (“equity method investments”) and reported within Other assets—Investments in and advances to affiliated companies or at fair value by electing the fair value option permitted by ASC 825“Financial Instruments”(“ASC 825”) and reported within Trading assets, Private equity and debt investments or Other assets—Other in consolidated balance sheets depending on the nature and purpose of the investments.

Equity investments in which Nomura has neither control nor significant influence are carried at fair value, with changes in fair value recognized through the consolidated statements of income and reported within Trading assets, Private equity and debt investments or Other assets—Other in consolidated balance sheets depending on the nature or purpose of the investments.

Certain consolidated entities are investment companies under ASC 946 “Financial Services—Investment Companies” (“ASC 946”). Nomura carries all of their investments at fair value, with changes in fair value recognized through the consolidated statements of income.

The Company’s principal subsidiaries include Nomura Securities Co., Ltd. (“NSC”), Nomura Securities International, Inc. (“NSI”), Nomura International plc (“NIP”) and Nomura Financial Products & Services, Inc. (“NFPS”).

All material intercompany transactions and balances have been eliminated on consolidation.

Use of estimates

Use of estimates—

Nomura uses accounting estimates to prepare these consolidated financial statements and they require difficult, subjective and complex judgments by management. Such estimates determined by management to be material include estimates regarding the fair value of financial instruments and litigation provisions. Estimates, by their nature, are based on underlying assumptions which require management judgment and depend on the extent of available information. Actual results in future periods may differ from current estimates, which could have a material impact on these consolidated financial statements.

Various references are made throughout the notes to these consolidated financial statements where critical accounting estimates based on management judgment have been made, the nature of the estimates, the underlying assumptions made by management used to derive those estimates and how these estimates affect the amounts reported in these consolidated financial statements.

Fair value of financial instruments

Fair value of financial instruments—

A significant amount of Nomura’s financial assets and financial liabilities are carried at fair value, with changes in fair value recognized through the consolidated statements of income and/ or the consolidated statements of comprehensive income. Use of a fair value measurement is either specifically required under U.S. GAAP or Nomura makes an election to use a fair value measurement for certain eligible items under the fair value option.

Other financial assets and financial liabilities are carried at fair value on a nonrecurring basis, where the primary measurement basis is not fair value. Fair value is only used in specific circumstances after initial recognition, such as to measure impairment.

In both cases, fair value is generally determined in accordance with ASC 820 “Fair Value Measurements and Disclosures” (“ASC 820”) which defines fair value as the amount that would be exchanged to sell a financial asset or transfer a financial liability in an orderly transaction between market participants at the measurement date. It assumes that the transaction occurs in Nomura’s principal market, or in the absence of a principal market, the most advantageous market for the relevant financial asset or financial liability. See Note 2 “Fair value measurements” for further information regarding how Nomura estimates fair value for specific types of financial instruments used in the ordinary course of business.

The fair values of financial assets and financial liabilities of consolidated VIEs which meet the definition of collateralized financing entities are both measured using the more observable fair value of the financial assets and financial liabilities.

Allowance for current expected credit losses

Allowance for current expected credit losses—

Management recognizes allowance for current expected credit losses on financial assets not carried at fair value and certain off-balance sheet financial instruments including unfunded loan commitments not carried at fair value in accordance with ASC 326, “Financial Instruments—Credit Losses” (“ASC 326”) which Nomura initially adopted on April 1, 2020. Prior to such date, allowances for credit losses were recognized for incurred losses rather than expected credit losses based on management’s estimate of probable losses incurred within these financial assets and off-balance sheet financial instruments.

Current expected credit losses are calculated over the expected life of the financial instruments in scope of the requirements on an individual or a portfolio basis, considering all relevant, reasonable supportable information available about the collectability of cash flows, including information about past events, current conditions and future forecasts. Accrued interest receivables are excluded from the amortized cost basis of financing receivables when calculating current expected credit losses.

The methodology used by Nomura to determine allowances for current expected credit losses in accordance with the CECL impairment model primarily depends on the nature of the financial instrument and whether certain practical expedients permitted by ASC 326 are applied by Nomura.

Allowances for current expected credit losses against recognized financial instruments are reported in the consolidated balance sheets within Allowances for current expected credit losses while allowances for current expected credit losses against off-balance sheet financial instruments are reported in the consolidated balance sheets within Other liabilities. All movements in the allowances are reported in the consolidated statements of income within Other expenses.

See Note 7 “Financing receivables” for further information including how allowance for current expected credit losses are calculated.

Transfers of financial assets

Transfers of financial assets—

Nomura accounts for the transfer of a financial asset as a sale when Nomura relinquishes control over the asset by meeting the following conditions: (a) the asset has been isolated from the transferor (even in bankruptcy or other receivership), (b) the transferee has the right to pledge or exchange the asset received, or if the transferee is an entity whose sole purpose is to engage in securitization or asset-backed financing activities, if, the holders of its beneficial interests have the right to pledge or exchange the beneficial interests held and (c) the transferor has not maintained effective control over the transferred asset.

In connection with its securitization activities, Nomura utilizes special purpose entities (“SPEs”) to securitize commercial and residential mortgage loans, government and corporate securities or other types of financial assets. Nomura’s involvement with SPEs includes structuring and underwriting, distributing and selling debt instruments and beneficial interests issued by SPEs to investors. Nomura derecognizes financial assets transferred in securitizations provided that Nomura has relinquished control over such assets and does not consolidate the SPE. Nomura may obtain or retain an interest in the financial assets, including residual interests in the SPEs dependent upon prevailing market conditions. Any such interests are accounted for at fair value and reported within Trading assets in the consolidated balance sheets with the change in fair value reported within Revenue—Net gain on trading in the consolidated statements of income.

Foreign currency translation

Foreign currency translation—

The financial statements of the Company’s subsidiaries and operations are measured using their functional currency which is the currency of the primary economic environment in which the entity operates. All assets and liabilities of subsidiaries and operations which have a functional currency other than Japanese Yen are translated into Japanese Yen at exchange rates in effect at the balance sheet date, and all revenue and expenses are translated at the average exchange rates for the respective years and the resulting translation adjustments are accumulated and reported within Accumulated other comprehensive income (loss) in NHI shareholders’ equity.

Foreign currency assets and liabilities are translated at exchange rates in effect at the balance sheet date and the resulting translation gains or losses are credited or charged to the consolidated statements of income.

Revenue from services provided to clients

Revenue from services provided to clients—

Nomura earns revenue through fees and commissions from providing financial services to clients across all three business divisions. These services primarily include trade execution and clearing services, distribution of fund unit services, financial advisory services, underwriting and distribution services and asset management services.

Revenues are recognized when or as the client obtains control of the service provided by Nomura which depends on when each of the key distinct substantive promises made by Nomura within the contract with the client (“performance obligations”) are satisfied. Such performance obligations are generally satisfied at a particularly point in time or, if certain criteria are met, over a period of time.

Revenues from providing distribution of fund units and clearing services are reported in the consolidated statements of income within Revenue—Commissions, revenues from asset management services are reported in Revenue—Asset management and portfolio service fees and revenues from financial advisory services, underwriting and distribution services are reported in Revenue—Fees from investment banking.

Costs to obtain or fulfill the underlying contract to provide services to a client are deferred as assets if certain criteria are met. These deferred costs, which are reported in the consolidated balance sheets within Other assets are released to the consolidated statements of income when the related revenue from providing the service is also recognized or earlier if there is evidence that the costs are not recoverable and therefore impaired.

Trading assets and trading liabilities

Trading assets and trading liabilities—

Trading assets primarily comprise debt securities, equity securities and derivative assets which are recognized on the consolidated balance sheets on a trade date basis and loans which are recognized on the consolidated balance sheets on a settlement date basis.

Financial assets are classified as being held for trading when any of the following criteria are met:

• The financial assets are originated or acquired with the intention to generate profit through sale of the financial assets in the short-term;

• The financial assets are part of a portfolio of identified financial instruments that are managed together for the purposes of short-term profit or arbitrage profit-taking; or

• The financial assets are derivative assets.

Trading liabilities primarily comprise short sales of securities and derivative liabilities, which are recognized on the consolidated balance sheets on a trade date basis. Trading assets and liabilities are carried at fair value and changes in fair value are generally reported within Revenue—Net gain on trading in the consolidated statements of income.

Certain nonderivative trading liabilities are held to economically hedge the price risk of investments in equity securities held for operating purposes. Changes in fair value of these trading liabilities are reported within Revenue—Gain (loss) on investments in equity securities in the consolidated statements of income.

Collateralized agreements and collateralized financing

Collateralized agreements and collateralized financing—

Collateralized agreements consist of reverse repurchase agreements disclosed as Securities purchased under agreements to resell and securities borrowing transactions disclosed as Securities borrowed. Collateralized financing consists of repurchase agreements disclosed as Securities sold under agreements to repurchase, securities lending transactions disclosed as Securities loaned and certain other secured borrowings.

Reverse repurchase and repurchase agreements principally involve the buying or selling of securities under agreements with clients to resell or repurchase these securities to or from those clients, respectively. These transactions are generally accounted for as collateralized agreements or collateralized financing transactions and are recognized in the consolidated balance sheets at the amount for which the securities were originally acquired or sold. Certain reverse repurchase and repurchase agreements are carried at fair value through election of the fair value option.

Nomura also enters into Gensaki Repo transactions which are the standard type of repurchase agreement used in Japanese financial markets. Gensaki Repo transactions contain margin requirements, rights of security substitution, and certain restrictions on the client’s right to sell or repledge the transferred securities. Gensaki Repo transactions are accounted for as collateralized agreements or collateralized financing transactions and are recognized on the consolidated balance sheets at the amount that the securities were originally acquired or sold.

Securities borrowing and lending transactions are generally accounted for as collateralized agreements and collateralized financing transactions, respectively. These transactions are generally cash collateralized and are recognized on the consolidated balance sheets at the amount of cash collateral advanced or received. Allowances for current expected credit losses recognized against securities borrowing transactions are not significant due to an ongoing monitoring of collateral and the short expected life of these transactions. Where Nomura acts as lenders in securities borrowing and lending transactions and receives securities that can be sold or pledged as collateral, Nomura recognizes the securities received at fair value within Other assets—Other and the obligation to return those securities as a liability within Other liabilities.

See Note 7 “Financing receivables” for further information including how allowances for current expected credit losses under ASC 326 are determined and the impact of the COVID-19 pandemic on the approach to calculation of current expected credit losses during the years ended March 31, 2021 and 2022.

Offsetting of collateralized agreements and collateralized financings

Reverse repurchase agreements and repurchase agreements (including Gensaki Repo transactions) accounted for as collateralized agreements and collateralized financing transactions, respectively, entered into with the same counterparty and documented under a master netting agreement are offset in the consolidated balance sheets where the specific criteria defined by ASC 210-20 “Balance Sheet—Offsetting” (“ASC 210-20”) are met. These criteria include requirements around the maturity of the transactions, the underlying systems on which the collateral is settled, associated banking arrangements and the legal enforceability of close-out and offsetting rights under the master netting agreement. Similarly, securities borrowing and lending transactions accounted for as collateralized agreements and collateralized financing transactions, respectively, entered into with the same counterparty and documented under a master netting agreement are also offset in the consolidated balance sheets where the specific criteria defined by ASC 210-20 are met.

Other secured borrowings consist primarily of secured borrowings from financial institutions and central banks in the inter-bank money market, and are carried at contractual amounts due.

Trading balances of secured borrowings consist of liabilities related to transfers of financial assets that are accounted for as secured financing transactions rather than sales under ASC 860 “Transfers and Servicing” (“ASC 860”) and are reported in the consolidated balance sheets within Long-term borrowings. The fair value option is generally elected for these transactions, which are carried at fair value on a recurring basis. See Note 6 “Securitizations and Variable Interest Entities” and Note 11 “Borrowings” for further information regarding these transactions.

All Nomura-owned securities pledged to counterparties where the counterparty has the right to sell or repledge the securities, including collateral transferred under Gensaki Repo transactions, are reported parenthetically within Trading assets as Securities pledged as collateral in the consolidated balance sheets.

See Note 5 “Collateralized transactions” for further information.

Derivatives

Derivatives—

Nomura uses a variety of derivatives, including futures, forwards, swaps and options, for both trading and non-trading purposes. Freestanding financial instruments which meet the accounting definition of derivatives are carried at fair value in the consolidated balance sheets and reported within Trading assets or Trading liabilities depending on whether fair value at the balance sheet date is positive or negative, respectively. Certain derivatives embedded in hybrid financial instruments such as structured notes and certificates of deposit are bifurcated from the host contract and are also carried at fair value in the consolidated balance sheets and reported within Short-term borrowings or Long-term borrowings depending on the maturity of the underlying host contract. Changes in fair value are recognized either through the consolidated statements of income or the consolidated statements of comprehensive income depending on the purpose for which the derivatives are used.

Derivatives used for trading purposes

Derivatives used for trading purposes, including bifurcated embedded derivatives, are carried at fair value with changes in fair value reported in the consolidated statements of income within Revenue—Net gain on trading.

Derivatives held for non-trading purposes

In addition to its trading activities, Nomura uses derivatives for other than trading purposes such as to manage risk exposures arising from recognized assets and liabilities, forecasted transactions and firm commitments. Derivatives held for non-trading purposes comprise derivatives formally designated as fair value or net investment hedges under ASC 815 “Derivatives and Hedging” (“ASC 815”) or economic expense hedges as follows:

Fair value hedges

Nomura designates certain derivative as fair value hedges of interest rate risk and foreign exchange risk arising from specific financial liabilities and foreign currency denominated non-trading debt securities, respectively. These derivatives are effective in reducing the risk associated with the exposure being hedged and they are highly correlated with changes in the fair value of the underlying hedged items, both at inception and

throughout the life of the hedging relationship. Changes in fair value of the hedging derivatives are reported together with those of the hedged financial assets and liabilities through the consolidated statements of income within Interest expense and Revenue—Other, respectively.

Net investment hedges

Nomura designates certain derivatives as hedges of the net investment in foreign operations related to specific subsidiaries with non-Japanese Yen functional currencies. When determining the effectiveness of net investment hedges, the effective portion of the change in fair value of the hedging derivative is determined by changes in spot exchange rates. Changes in fair value of the hedging derivatives attributable to changes in the difference between the forward rate and spot rate is excluded from the measurement of hedge effectiveness and are reported in the consolidated statements of income within Revenue—Other. All other movements in fair value of highly effective net investment hedging derivatives are reported through NHI shareholders’ equity within Accumulated other comprehensive income (loss).

Economic expense hedges

Nomura designates certain derivatives as economic expense hedges to manage equity price risk or foreign currency risk of certain expenses arising from forecasted transactions or firm commitments. Changes in fair value of these derivatives are reported in the same line item in the consolidated statements of income where expenses arising from the hedged transactions are reported.

Offsetting of derivatives

Derivative assets and liabilities with the same counterparty documented under a legally enforceable master netting agreement and the related cash collateral receivables and payables are presented on a net basis in the consolidated balance sheets where the specific criteria defined by ASC 210-20 and ASC 815 are met.

Settlement-to-market derivatives

Exchange traded and centrally cleared OTC derivatives typically involve daily variation margin payments and receipts which reflect changes in the fair value of the related derivatives. Such variation margin amounts are accounted for as either a partial settlement of the derivative or as a separate cash collateral receivable or payable depending on the legal form of the arrangement with the relevant central clearing counterparty.

See Note 3 “Derivatives and hedging activities” for further information.

Loans receivable

Loans receivable—

Loans receivable are loans which management intends to hold for the foreseeable future. Loans receivable are either carried at fair value or at amortized cost. Interest earned on loans receivable is reported in the consolidated statements of income within Revenue—Interest and dividends.

Loans receivable carried at fair value

Certain loans which are risk managed on a fair value basis are carried at fair value through election of the fair value option. Nomura makes this election to mitigate volatility in the consolidated statements of income caused by the difference in measurement basis that would otherwise exist between the loans and the derivatives used to risk manage those loans. Changes in the fair value of loans receivable carried at fair value are reported in the consolidated statements of income within Revenue—Net gain on trading.

Loans receivable carried at amortized cost

Loans receivable which are not carried at fair value are carried at amortized cost. Amortized cost represents cost adjusted for deferred fees and direct costs, unamortized premiums or discounts on purchased loans and after deducting applicable allowances for current expected credit losses under ASC 326 which Nomura initially adopted from April 1, 2020.

Loan origination fees, net of direct origination costs, are amortized to Revenue—Interest and dividends as an adjustment to yield over the life of the loan.

Modifications of loans receivable where the borrower is in financial difficulty and Nomura has granted a financial concession are typically accounted for as troubled debt restructurings (“TDRs”). Consistent with guidance issued by U.S. banking regulators in March 2020 as a result of the COVID-19 pandemic, certain modifications of loans receivable which met the above criteria were not accounted for TDRs nor the loan classified as impaired provided the borrower was current with payments prior to the COVID-19 pandemic, the nature of the concession was short-term and only permitted a payment delay, waiver of fees or extension of repayment terms. Such guidance has no longer been applied by Nomura since October 1, 2020.

See Note 7 “Financing receivables” for further information including how allowances for current expected credit losses under ASC 326 are determined.

Other receivables

Other receivables—

Receivables from customers include amounts receivable on client securities transactions, amounts receivable from clients for failed to deliver securities and receivables for commissions receivable. Receivables from other than customers include amounts receivable from brokers and dealers for failed to deliver securities, margin deposits, cash collateral receivables for derivative transactions, and net receivables arising from unsettled securities transactions. The net receivable arising from unsettled securities transactions reported within Receivables from other than customers was ¥nil million and ¥nil as of March 31, 2021 and March 31, 2022, respectively.

These amounts are carried at contractual amounts due less any applicable allowance for current expected credit losses recognized under ASC 326 which Nomura initially adopted from April 1, 2020.

See Note 7 “Financing receivables” for further information including how allowances for current expected credit losses under ASC 326 are determined.

Loan commitments

Loan commitments—

Unfunded loan commitments written by Nomura are accounted for as either off-balance sheet instruments, or are carried at fair value on a recurring basis either as trading instruments or through election of the fair value option.

These loan commitments are generally accounted for in a manner consistent with the accounting for the loan receivable upon funding. Where the loan receivable will be classified as a trading asset or will be elected for the fair value option, the loan commitment is also generally held at fair value, with changes in fair value reported in the consolidated statements of income within Revenue—Net gain on trading. Loan commitment fees integral to the loan commitment are recognized as part of the fair value of the commitment.

For loan commitments where the loan will be held for the foreseeable future and will not be elected for the fair value option, Nomura recognizes allowances for current expected credit losses in accordance with ASC 326 which Nomura initially adopted from April 1, 2020. As of March 31, 2020, the allowance for incurred credit losses reflected management’s best estimate of probable losses expected incurred for these loan commitments. Loan commitment fees are generally deferred and recognized over the term of the loan when funded as an adjustment to yield. If drawdown of the loan commitment is considered remote, loan commitment fees are recognized over the commitment period as service revenue.

See Note 7 “Financing receivables” for further information including how allowances for current expected credit losses under ASC 326 are determined.

Payables and deposits

Payables and deposits—

Payables to customers include amounts payable on client securities transactions and are generally measured at contractual amounts due.

Payables to other than customers include payables to brokers and dealers for failed-to-receive securities, cash collateral payable for derivative transactions, certain collateralized agreements and financing transactions and net payables arising from unsettled securities transactions. Amounts are measured at contractual amounts due. The net payable arising from unsettled securities transactions reported within Payables to other than customers was ¥205,211 and ¥67,258 million as of March 31, 2021 and March 31, 2022, respectively.

Deposits received at banks represent amounts held on deposit within Nomura’s banking subsidiaries and are measured at contractual amounts due.

Office buildings, land, equipment and facilities

Office buildings, land, equipment and facilities—

Office buildings, land, equipment and facilities, owned and held for use by Nomura are stated at cost, net of accumulated depreciation and amortization, except for land, which is stated at cost. Significant renewals and additions are capitalized at cost. Maintenance, repairs and minor renewals are expensed as incurred in the consolidated statements of income.

Leases and subleases entered into by Nomura as either lessor or lessee are classified as either operating or finance leases on inception date in accordance with ASC 842 “Leases” which Nomura adopted from April 1, 2019. On lease commencement date, Nomura as lessee recognizes right-of-use (“ROU”) assets and lease liabilities which are reported within Other assets—Office buildings, land, equipment and facilities and Other liabilities, respectively in the consolidated balance sheets.

Lease liabilities are initially measured at present value of the future minimum lease payments over the expected lease term. The future minimum lease payments are discounted using a relevant Nomura incremental borrowing rate as derived from information available at lease commencement date. The expected lease term is generally determined based on the contractual maturity of the lease, and adjusted for periods covered by options to extend or terminate the lease when Nomura is reasonably certain to exercise those options. ROU assets are initially measured at the amount of lease liabilities, and adjusted for any prepaid lease payments, initial direct costs incurred and any lease incentives received.

After lease commencement date, for operating leases Nomura as lessee recognizes lease expense over the lease term generally on a straight-line basis within Occupancy and related depreciation or Information

processing and communications in the consolidated statements of income. While for finance leases, Nomura recognizes amortization charges of ROU assets over the lease term and interest expense on finance lease liabilities.

Depreciation and amortization charges of owned assets are generally computed using the straight-line method and recognized over the estimated useful lives of each asset. The estimated useful life of an asset takes into consideration technological change, normal deterioration and actual physical usage by Nomura. Leasehold improvements are depreciated over the shorter of their useful life or the term of corresponding lease.

The estimated useful lives for significant asset classes are as follows:

Office buildings	3 to 50 years
Equipment and facilities	2 to 20 years
Software	3 to 10 years

Long-lived assets, including ROU assets and software assets but excluding goodwill and indefinite-lived intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the estimated future undiscounted cash flows generated by the asset is less than the carrying amount of the asset, a loss is recognized to the extent that the carrying value exceeds its fair value.

See Note 8 “Leases” for further information.

Investments in equity securities

Investments in equity securities—

Nomura holds minority stakes in the equity securities of unaffiliated Japanese financial institutions and corporations in order to promote existing and potential business relationships. These companies often have similar investments in Nomura. Such cross-holdings are a customary business practice in Japan and provide a way for companies to manage shareholder relationships.

These investments, which Nomura refers to as being held for operating purposes, are carried at fair value and reported within Other assets—Investments in equity securities in the consolidated balance sheets, with changes in fair value reported within Revenue—Gain (loss) on investments in equity securities in the consolidated statements of income.

Other non-trading debt and equity securities

Other non-trading debt and equity securities—

Certain non-trading subsidiaries within Nomura hold debt securities and minority stakes in equity securities for non-trading purposes. Non-trading securities held by non-trading subsidiaries are carried at fair value and reported within Other assets—Non-trading debt securities and Other assets—Other in the consolidated balance sheets with changes in fair value reported within Revenue—Other in the consolidated statements of income. Realized gains and losses on non-trading securities are reported within Revenue—Other in the consolidated statements of income.

Short-term and long-term borrowings

Short-term and long-term borrowings—

Short-term borrowings are defined as borrowings which are due on demand, which have a contractual maturity of one year or less at issuance date, or which have a longer contractual maturity but which contain

features outside of Nomura’s control that allows the investor to demand redemption within one year from original issuance date. Short-term and long-term borrowings primarily consist of commercial paper, bank borrowings, and certain structured notes issued by Nomura and SPEs consolidated by Nomura, and financial liabilities recognized in transfers of financial assets which are accounted for as financings rather than sales under ASC 860 (“secured financing transactions”). Of these financial liabilities, certain structured notes and secured financing transactions are accounted for at fair value on a recurring basis through election of the fair value option. Other short and long-term borrowings are carried at amortized cost.

Structured notes are debt securities which contain embedded features (often meeting the accounting definition of a derivative) that alter the return to the investor from simply receiving a fixed or floating rate of interest to a return that depends upon some other variable(s) such as an equity or equity index, commodity price, foreign exchange rate, credit rating of a third party or more complex interest rate calculation. Structured borrowings are borrowings that have similar characteristics as structured notes.

All structured notes and certain structured borrowings issued by Nomura are carried at fair value on a recurring basis through election of the fair value option. This blanket election for structured notes and certain structured borrowings are made primarily to mitigate the volatility in the consolidated statements of income caused by differences in the measurement basis for structured notes and the derivatives used to risk manage those positions and to generally simplify the accounting Nomura applies to these financial instruments.

Changes in the fair value of structured notes elected for the fair value option are reported within Revenue—Net gain on trading in the consolidated statements of income, except for those attributable to Nomura’s own creditworthiness which are reported within Other comprehensive income in the consolidated balance sheets.

See Note 11 “Borrowings” for further information.

Income taxes

Income taxes—

Deferred tax assets and liabilities are recognized to reflect the expected future tax consequences of operating loss carryforwards, tax credit carryforwards and temporary differences between the carrying amounts for financial reporting purposes and the tax bases of assets and liabilities based upon enacted tax laws and tax rates. Nomura recognizes deferred tax assets to the extent it believes that it is more likely than not that a benefit will be realized. A valuation allowance is established against deferred tax assets for tax benefits available to Nomura that are not deemed more likely than not to be realized.

Deferred tax assets and deferred tax liabilities that relate to the same tax-paying component within a particular tax jurisdiction are offset in the consolidated balance sheets. Net deferred tax assets and net deferred tax liabilities are reported within Other assets—Other and Other liabilities in the consolidated balance sheets.

Nomura recognizes and measures unrecognized tax benefits based on Nomura’s estimate of the likelihood, based on technical merits, that tax positions will be sustained upon examination based on the facts and circumstances and information available at the end of each period. Nomura adjusts the level of unrecognized tax benefits when there is more information available, or when an event occurs requiring a change. The reassessment of unrecognized tax benefits could have a material impact on Nomura’s effective tax rate in the period in which it occurs.

Nomura reports income tax-related interest and penalties within Income tax expense in the consolidated statements of income.

See Note 15 “Income taxes” for further information.

Stock-based and other compensation awards

Stock-based and other compensation awards—

Stock-based awards issued by Nomura to senior management and other employees are classified as either equity or liability awards depending on the terms of the award.

Stock-based awards such as Stock Acquisition Rights (“SARs”) and Restricted Stock Units (“RSUs”) which are expected to be settled by the delivery of the Company’s common stock are classified as equity awards. For these awards, total compensation cost is generally fixed at the grant date and measured using the grant-date fair value of the award, net of any amount the employee is obligated to pay and estimated forfeitures.

Stock-based awards such as Notional Stock Units (“NSUs”) and Collared Notional Stock Units (“CSUs”) which are expected to be settled in cash are classified as liability awards. Liability awards are remeasured to fair value at each balance sheet date, net of estimated forfeitures with the final measurement of cumulative compensation cost equal to the settlement amount.

For both equity and liability awards, fair value is determined either by using option pricing models, the market price of the Company’s common stock or the price of the third party index, as appropriate. Compensation cost is recognized in the consolidated statements of income over the requisite service period, which generally is equal to the contractual vesting period. Where an award has graded vesting, compensation expense is recognized using the accelerated recognition method.

Certain deferred compensation awards include “Full Career Retirement” (“FCR”) provisions which permit recipients of the awards to continue to vest in the awards upon voluntary termination or by claiming FCR during a pre-defined election window if certain criteria based on corporate title and length of service within Nomura are met. The requisite service period for these awards ends on the earlier of the contractual vesting date and the date that the recipients become eligible for or claim FCR.

See Note 14 “Deferred compensation awards” for further information.

Earnings per share

Earnings per share—

The computation of basic earnings per share is based on the weighted average number of shares outstanding during the year. Diluted earnings per share reflects the assumed conversion of all dilutive securities based on the most advantageous conversion rate or exercise price available to the investors, and assuming conversion of convertible debt under the if-converted method.

See Note 12 “Earnings per share” for further information.

Cash and cash equivalents

Cash and cash equivalents—

Nomura defines cash and cash equivalents as cash on hand and demand deposits with banks.

Goodwill and intangible assets

Goodwill and intangible assets—

Goodwill is recognized upon completion of a business combination as the difference between the purchase price and the fair value of the net assets acquired. Subsequent to initial recognition, goodwill is not amortized but

is tested for impairment at a reporting unit level during the fourth quarter of each fiscal year, or more frequently during earlier interim periods if events or circumstances indicate there may be impairment. Nomura’s reporting units are at the same level as or one level below its business segments.

Nomura tests goodwill of each separate reporting unit by initially qualitatively assessing whether events and circumstances indicate that it is more likely than not (i.e., greater than 50% likelihood) that a reporting unit’s fair value is less than its carrying amount. If such assessment indicates fair value is not less than the carrying value, the reporting unit is deemed not to be impaired and no further analysis is required. If it is more likely than not that fair value of the reporting unit is below its carrying value, a quantitative test is then performed. Following the adoption of ASU 2017-04 “Simplifying the Test for Goodwill Impairment” effective from April 1, 2020, a goodwill impairment loss is now recognized through earnings as the excess of the carrying amount of a reporting unit, including goodwill, over its fair value but limited to the total amount of goodwill allocated to the reporting unit. Prior to such date, an impairment loss was only recognized if the estimated implied fair value of the goodwill is below its carrying value. Intangible assets not subject to amortization (“indefinite-lived intangible assets”) are tested for impairment on an individual asset basis during the fourth quarter of each fiscal year, or more frequently during earlier interim periods if events or circumstances indicate there may be impairment. Similar to goodwill, Nomura tests an indefinite-lived intangible asset by initially qualitatively assessing whether events or circumstances indicate that it is more likely than not that the fair value of the intangible asset is less than its carrying amount. If such assessment indicates fair value is not less than the carrying value, the intangible asset is deemed not to be impaired and no further analysis is required. If it is more likely than not that the fair value of the intangible asset is below its carrying value, the current estimated fair value of the intangible asset is compared with its carrying value. An impairment loss is recognized if the carrying value of the intangible asset exceeds its estimated fair value.

Intangible assets with finite lives (“finite-lived intangible assets”) are amortized over their estimated useful lives and tested for impairment either individually or with other assets (“asset group”) when events and circumstances indicate that the carrying value of the intangible asset (or asset group) may not be recoverable.

A finite-lived intangible asset is impaired when its carrying amount or the carrying amount of the asset group exceeds its fair value. An impairment loss is recognized only if the carrying amount of the intangible asset (or asset group) is not recoverable and exceeds its fair value.

For both goodwill and intangible assets, to the extent an impairment loss is recognized, the loss establishes a new cost basis for the asset which cannot be subsequently reversed.

See Note 10 “Other assets—Office buildings, land, equipment and facilities and Other / Other liabilities” for further information.

Nomura’s equity method investments are tested in their entirety for other-than-temporary impairment when there is an indication of impairment. The underlying assets associated with the equity method investments, including goodwill, are not tested separately for impairment.

Employee benefit plans

Employee benefit plans—

Nomura provides certain eligible employees with various benefit plans, including pensions and other post-retirement benefits. These benefit plans are classified as either defined benefit plans or defined contribution plans.

Plan assets and benefit obligations, as well as the net periodic benefit cost of a defined benefit pension or post-retirement benefit plan, are recognized based on various actuarial assumptions such as discount rates,

expected return on plan assets and future compensation levels at the balance sheet date. Actuarial gains and losses in excess of 10% of the greater of the projected benefit obligation or the fair value of plan assets and unrecognized prior service costs or credits are amortized to net periodic benefit cost on a straight-line basis over the average remaining service life of active employees expected to receive benefits. The overfunded or underfunded status of a plan is reported within Other assets—Other or Other liabilities in the consolidated balance sheets, and changes in funded status are reflected in net periodic benefit cost and Other comprehensive income (loss) on a net-of-tax basis in the consolidated statements of comprehensive income.

The net periodic pension and other benefit cost of defined contribution plans is recognized within Compensation and benefits in the consolidated statements of income when the employee renders service to Nomura, which generally coincides with when contributions to the plan are made.

See Note 13 “Employee benefit plans” for further information.
