Item 2. Operating and Financial Review

1. Risk Factors

Significant changes in our Risk Factors which were described on the annual securities report are stated below. The titles below correspond to the titles of “Part I Corporate Information—Item 2. Operating and Financial Review—2. Risk Factors” in the annual securities report.

The discussion below contains future matters that are based on the assessments made as of the date of submission of this report (November 14, 2018), unless noted separately.

Our business is subject to substantial legal, regulatory and reputational risks

Extensive regulation of our businesses limits our activities and may subject us to significant penalties and losses

The financial services industry is subject to extensive regulation. We are subject to increasing regulation by governmental and self-regulatory organizations in Japan and in virtually all other jurisdictions in which we operate, and such governmental and regulatory scrutiny may increase as our operations expand or as laws change. In addition, while regulatory complexities increase, possibilities of extra-territorial application of a regulation in one jurisdiction to business activities outside of such jurisdiction may also increase. These regulations are broadly designed to ensure the stability of financial systems and the integrity of the financial markets and financial institutions, and to protect clients and other third parties who deal with us, and often limit our activities and/or affect our profitability, through net capital, client protection and market conduct requirements. In addition, on top of traditional finance-related legislation, the scope of laws and regulations applying to, and/or impacting on, our operations may become wider depending on the situation of the wider international political and economic environment or policy approaches taken by governmental authorities in respect of regulatory application or law enforcement. In particular, the number of investigations and proceedings against the financial services industry by governmental and self-regulatory organizations has increased substantially and the consequences of such investigations and proceedings have become more severe in recent years, and we are subject to face the risk of such investigations and proceedings. For example, the U.S. Department of Justice (the “DOJ”) conducted an investigation regarding residential mortgage-backed securities securitized by some of our U.S. subsidiaries prior to 2009. On October 15, 2018, the U.S. subsidiaries settled the investigation with the DOJ and agreed to pay USD 480 million. Although we have policies in place to prevent violations of such laws and regulations, we may not always be able to prevent violations, and we could be fined, prohibited from engaging in some of our business activities, ordered to improve our internal governance procedures or be subject to revocation of our license to conduct business. Our reputation could also suffer from the adverse publicity that any administrative or judicial sanction against us may create, which may negatively affect our business opportunities and ability to secure human resources. As a result of any such sanction, we may lose business opportunities for a period of time, even after the sanction is lifted, if and to the extent that our clients, especially public institutions, decide not to engage us for their financial transactions. In addition, certain market participants may refrain from investing in or entering into transactions with us if we engage in business activities in regions subject to international sanctions, even if our activities do not constitute violations of sanctions laws and regulations.

2. Operating, Financial and Cash Flow Analyses by Management

(1) Operating Results

Nomura reported net revenue of ¥554.9 billion, non-interest expenses of ¥540.8 billion, income before income taxes of ¥14.1 billion, and net loss attributable to NHI shareholders of ¥6.0 billion for the six months ended September 30, 2018.

The breakdown of net revenue and non-interest expenses on the consolidated statements of income are as follows:

3

Business Segment Information

Results by business segment are noted below.

Reconciliations of Net revenue and Income (loss) before income taxes on segment results of operations and the consolidated statements of income are set forth in Item 4. Financial Information, 1. Consolidated Financial Statements, Note 15. “Segment and geographic information.”

Net revenue

Retail

Net revenue was ¥178.5 billion primarily due to deterioration of retail investors’ sentiment. Non-interest expenses were ¥146.4 billion and income before income taxes was ¥32.1 billion. Retail client assets were ¥122.8 trillion as of September 30, 2018, a ¥5.1 trillion increase from March 31, 2018.

Asset Management

Net revenue was ¥50.8 billion. Non-interest expenses were ¥31.6 billion and income before income taxes was ¥19.2 billion. Assets under management were ¥52.8 trillion as of September 30, 2018, a ¥2.8 trillion increase from March 31, 2018, primarily due to market appreciation and net inflow into funds such as ETF.

4

Wholesale

Net revenue was ¥284.9 billion. Non-interest expenses were ¥287.5 billion and loss before income taxes was ¥2.5 billion.

The breakdown of net revenue for Wholesale is as follows:

Global Markets net revenue was ¥236.0 billion. Fixed Income net revenue decreased from ¥169.2 billion in the previous year to ¥127.2 billion because of uncertain markets and turmoil in emerging markets which led to a tough environment for the trading business. Equities net revenue decreased from ¥116.4 billion in the previous year to ¥108.7 billion due to a decrease in trading volume in the cash markets. Investment banking net revenue was ¥49.0 billion.

Nomura established Client Financing and Solutions (“CFS”) in April, 2018. In CFS, Global Markets and Investment Banking co-work and revenue generated from CFS is allocated to Global Markets and Investment Banking in a certain manner. Accordingly, we reclassified a part of net revenue which previously belonged to Global Markets to Investment Banking.

Other Operating Results

Other operating results include net gain (loss) related to economic hedging transactions, realized gain (loss) on investments in equity securities held for operating purposes, equity in earnings of affiliates, corporate items, and other financial adjustments. Other operating results for the six months ended September 30, 2018 include losses of ¥0.8 billion from changes in the fair value of derivative liabilities attributable to the change in its own creditworthiness and losses of ¥0.2 billion from changes in counterparty credit spread. Net revenue was ¥39.7 billion, non-interest expenses were ¥75.4 billion and loss before income taxes was ¥35.7 billion for the six months ended September 30, 2018.

Cyber Security Incident

One of our foreign subsidiaries recently experienced a cyber incident that resulted in the unauthorized access to certain of its systems including client information. We may suffer financial loss through reputational damage, legal liability and enforcement actions against us, and expect to incur increased costs for our operations generally, resulting from and in connection with the remediation of this incident and to strengthen and enhance cyber security within other Nomura group companies.

Geographic Information

Please refer to Item 4. Financial Information, 1. Consolidated Financial Statements, Note 16. “Segment and geographic information” for net revenue and income (loss) before income taxes by geographic allocation.

Cash Flow Information

Please refer to “(6) Liquidity and Capital Resources.”

(2) Assets and Liabilities Associated with Investment and Financial Services Business

1) Exposure to Certain Financial Instruments and Counterparties

Market conditions continue to impact numerous products to which we have certain exposures. We also have exposures to Special Purpose Entities (“SPEs”) and others in the normal course of business.

Leveraged Finance

We provide loans to clients in connection with leveraged buy-outs and leveraged buy-ins. As this type of financing is usually initially provided through a commitment, we have both funded and unfunded exposures on these transactions.

The following table sets forth our exposure to leveraged finance by geographic location of the target company as of September 30, 2018.

Special Purpose Entities

Our involvement with these entities includes structuring, underwriting, as well as, subject to prevailing market conditions, distributing and selling debt instruments and beneficial interests issued by these entities. In the normal course of securitization and equity derivative activities business, we also act as a transferor of financial assets to, and underwriter, distributor and seller of repackaged financial instruments issued by these entities. We retain, purchase and sell variable interests in SPEs in connection with our market-making, investing and structuring activities. Our other types of involvement with SPEs include guarantee agreements and derivative contracts.

For further discussion on Nomura’s involvement with variable interest entities (“VIEs”), see Item 4. Financial Information, 1. Consolidated Financial Statements, Note 7. “Securitizations and Variable Interest Entities.”

2) Fair Value of Financial Instruments

A significant amount of our financial instruments are carried at fair value, with changes in fair value recognized through the consolidated statements of income or the consolidated statements of comprehensive income on a recurring basis. Use of fair value is either specifically required under U.S. GAAP or we make an election to use fair value 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 accordance with Accounting Standard Codification (“ASC”) 820 “Fair Value Measurements and Disclosures”, all financial instruments measured at fair value have been categorized into a three-level hierarchy based on the transparency of inputs used to establish fair value.

6

Level 3 financial assets as a proportion of total financial assets, carried at fair value on a recurring basis was 4% as of September 30, 2018 as listed below:

Please refer to Item 4. Financial Information, 1. Consolidated Financial Statements, Note 2. “Fair value measurements” for further information.

(3) Trading Activities

Assets and liabilities for trading purposes

Please refer to Item 4. Financial Information, 1. Consolidated Financial Statements, Note 2. “Fair value measurements” and Note 3. “Derivative instruments and hedging activities” regarding the balances of assets and liabilities for trading purposes.

Risk management of trading activity

We adopt Value at Risk (“VaR”) for measurement of market risk arising from trading activity.

(4) Deferred Tax Assets Information

Details of deferred tax assets and liabilities

The following table presents details of deferred tax assets and liabilities reported within Other assets—Other and Other liabilities, respectively, in the consolidated balance sheets as of September 30, 2018.

Calculation method of deferred tax assets

In accordance with U.S. GAAP, we recognize deferred tax assets to the extent we believe that it is more likely than not that a benefit will be realized. A valuation allowance is provided for tax benefits available to us, which are not deemed more likely than not to be realized.

(5) Qualitative Disclosures about Market Risk

1) Risk Management

Nomura defines risks as (i) the potential erosion of Nomura’s capital base due to unexpected losses arising from risks to which its business operations are exposed, such as market risk, credit risk, operational risk and model risk, (ii) liquidity risk, the potential lack of access to funds or higher cost of funding than normal levels due to a deterioration in Nomura’s creditworthiness or deterioration in market conditions, and (iii) business risk, the potential failure of revenues to cover costs due to a deterioration in the earnings environment or a deterioration in the efficiency or effectiveness of its business operations.

A fundamental principle established by Nomura is that all employees shall regard themselves as principals of risk management and appropriately manage these risks. Nomura seeks to promote a culture of proactive risk management throughout all levels of the organization and to limit risks to the confines of its risk appetite. The risk management framework that Nomura uses to manage these risks consists of its risk appetite, risk management governance and oversight, the management of financial resources, the management of all risk classes, and processes to measure and control risks.

2) Global Risk Management Structure

The Board of Directors has established the “Structure for Ensuring Appropriate Business of Nomura Holdings, Inc.” as the Company’s basic principle and set up a framework for managing the risk of loss based on this. In addition, they are continuously making efforts to improve, strengthen and build up our risk management capabilities under this framework. Moreover, the Group Integrated Risk Management Committee (“GIRMC”), upon delegation from the Executive Management Board (“EMB”), has established the Risk Management Policy, describing Nomura’s overall risk management framework including the fundamental risk management principles followed by Nomura.

Market Risk Management

Market risk is the risk of loss arising from fluctuations in the value of financial assets and liabilities (including off-balance sheet items) due to fluctuations in market factors (interest rates, foreign exchange rates, prices of securities and others). Effective management of market risk requires the ability to analyze a complex and evolving portfolio in a constantly changing global market environment, identify problematic trends and ensure that appropriate action is taken in a timely manner.

Nomura uses a variety of statistical risk measurement tools to assess and monitor market risk on an ongoing basis, including, but not limited to, VaR, Stressed VaR (“SVaR”) and Incremental Risk Charge (“IRC”). In addition, Nomura uses sensitivity analysis and stress testing to measure and analyze its market risk. Sensitivities are measures used to show the potential changes to a portfolio due to standard moves in market risk factors. They are specific to each asset class and cannot usually be aggregated across risk factors. Stress testing enables the analysis of portfolio risks or tail risks, including non-linear behaviors and can be aggregated across risk factors at any level of the group hierarchy, from group level to business division, units or desk levels. Market risk is monitored against a set of approved limits, with daily reports and other management information provided to the business units and senior management.

Credit Risk Management

Credit risk is the risk of loss arising from an obligor’s default, insolvency or administrative proceeding which results in the obligor’s failure to meet its contractual obligations in accordance with agreed terms. This includes both on and off-balance sheet exposures. It is also the risk of loss arising through a credit valuation adjustment (“CVA”) associated with deterioration in the creditworthiness of a counterparty.

Nomura manages credit risk on a global basis and on an individual Nomura legal entity basis.

The measurement, monitoring and management of credit risk at Nomura are governed by a set of global policies and procedures. Credit Risk Management (“CRM”), a global function within the Risk Management Division, is responsible for the implementation and maintenance of these policies and procedures. These policies are authorized by the GIRMC and/or Global Risk Strategic Committee (“GRSC”), prescribe the basic principles of credit risk management and set delegated authority which enables CRM personnel to set Credit limits.

Credit risk is managed by CRM together with various global and regional risk committees. This ensures transparency of material credit risks and compliance with established credit limits, the approval of material extensions of credit and the escalation of risk concentrations to appropriate senior management.

9

CRM operates as a credit risk control function within the Risk Management Division, reporting to the Chief Risk Officer. The process for managing credit risk at Nomura includes:

For regulatory capital calculation purposes, Nomura has been applying the Foundation Internal Rating Based Approach in calculating credit risk weighted asset since the end of March 2011. The Standardized Approach is applied to certain business units or asset types, which are considered immaterial to the calculation of credit risk weighted assets.

The exposure calculation model used for counterparty credit risk management has also been used for the Internal Model Method based exposure calculation for regulatory capital reporting purposes since the end of December 2012.

Operational Risk Management

Operational risk is the risk of loss resulting from inadequate or failed internal processes, people, and systems or from external events. It excludes strategic risk (the risk of loss as a result of poor strategic business decisions), but includes the risk of breach of legal and regulatory requirements, and the risk of damage to Nomura’s reputation if caused by an operational risk.

Nomura adopts the industry standard “Three Lines of Defence” for the management of operational risk, comprising the following elements:

An Operational Risk Management Framework has been established in order to allow Nomura to identify, assess, manage, monitor and report on operational risk. The GIRMC, with delegated authority from the EMB has formal oversight over the management of operational risk.

Nomura uses the Standardized Approach for calculating regulatory capital for operational risk. This involves using a three-year average of gross income allocated to business lines, which is multiplied by a fixed percentage (“Beta Factor”) determined by the Financial Services Agency of Japan (“FSA”), to establish the amount of required operational risk capital.

Model Risk Management

Nomura uses risk models for regulatory and economic capital calculations and valuation models for pricing and sensitivity calculations of positions. Model risk is the risk of loss arising from model errors or incorrect or inappropriate model application with regard to valuation models and risk models. Errors can occur at any point from model assumptions through to implementation. In addition, the quality of model outputs depends on the quality of model parameters and any input data. Even a fundamentally sound model producing accurate outputs consistent with the design objective of the model may exhibit high model risk if it is misapplied or misused. To address these risks, Nomura has established its model risk appetite.

Nomura has documented policies and procedures in place, approved by the GIRMC and/or GRSC, which define the process and validation requirements for implementing changes to valuation and risk models. Before these models are put into official use, the Model Validation Group (“MVG”) is responsible for validating their integrity and comprehensiveness independently from those who design and build them. All models are also subject to an annual re-approval process by MVG to ensure they remain suitable. In addition, a Model Performance Monitoring process has been established to identify and assess specific events, that can indicate that a Model is not performing as it should or is potentially unsuitable and to determine what actions (for example, additional validation work) might be necessary. For changes with an impact above certain materiality thresholds, model approval is required.

(6) Liquidity and Capital Resources

Funding and Liquidity Management

Overview

We define liquidity risk as the risk of loss arising from difficulty in securing the necessary funding or from a significantly higher cost of funding than normal levels due to deterioration of the Nomura Group’s creditworthiness or deterioration in market conditions. This risk could arise from Nomura-specific or market-wide events such as inability to access the secured or unsecured debt markets, a deterioration in our credit ratings, a failure to manage unplanned changes in funding requirements, a failure to liquidate assets quickly and with minimal loss in value, or changes in regulatory capital restrictions which may prevent the free flow of funds between different group entities. Our global liquidity risk management policy is based on liquidity risk appetite formulated by the Executive Management Board (“EMB”). Nomura’s liquidity risk management, under market-wide stress and in addition, under Nomura-specific stress, seeks to ensure enough continuous liquidity to meet all funding requirements and unsecured debt obligations across one year and 30-day periods, respectively, without raising funds through unsecured funding or through the liquidation of assets. We are required to meet regulatory notice on the liquidity coverage ratio issued by the FSA.

We have in place a number of liquidity risk management frameworks that enable us to achieve our primary liquidity objective. These frameworks include (1) Centralized Control of Residual Cash and Maintenance of Liquidity Portfolio; (2) Utilization of Unencumbered Assets as Part of Our Liquidity Portfolio; (3) Appropriate Funding and Diversification of Funding Sources and Maturities Commensurate with the Composition of Assets; (4) Management of Credit Lines to Nomura Group Entities; (5) Implementation of Liquidity Stress Tests; and (6) Contingency Funding Plan.

Our EMB has the authority to make decisions concerning group liquidity management. The Chief Financial Officer (“CFO”) has the operational authority and responsibility over our liquidity management based on decisions made by the EMB.

1. Centralized Control of Residual Cash and Maintenance of Liquidity Portfolio.

We centrally control residual cash held at Nomura Group entities for effective liquidity utilization purposes. As for the usage of funds, the CFO decides the maximum amount of available funds, provided without posting any collateral, for allocation within Nomura and the EMB allocates the funds to each business division. Global Treasury monitors usage by businesses and reports to the EMB.

In order to enable us to transfer funds smoothly between group entities, we limit the issuance of securities by regulated broker-dealers or banking entities within the Nomura Group and seek to raise unsecured funding primarily through the Company or through unregulated subsidiaries. The primary benefits of this strategy include cost minimization, wider investor name recognition and greater flexibility in providing funding to various subsidiaries across the Nomura Group.

To meet any potential liquidity requirement, we maintain a liquidity portfolio, managed by Global Treasury apart from other assets, in the form of cash and highly liquid, unencumbered securities that may be sold or pledged to provide liquidity. As of September 30, 2018, our liquidity portfolio was ¥4,953.4 billion which sufficiently met liquidity requirements under the stress scenarios.

2. Utilization of Unencumbered Assets as Part of Our Liquidity Portfolio.

In addition to our liquidity portfolio, we had unencumbered assets comprising mainly of unpledged trading assets that can be used as an additional source of secured funding. Global Treasury monitors other unencumbered assets and can, under a liquidity stress event when the contingency funding plan has been invoked, monetize and utilize the cash generated as a result. The aggregate of our liquidity portfolio and other unencumbered assets was sufficient against our total unsecured debt maturing within one year.

3. Appropriate Funding and Diversification of Funding Sources and Maturities Commensurate with the Composition of Assets

We seek to maintain a surplus of long-term debt and equity above the cash capital requirements of our assets. We also seek to achieve diversification of our funding by market, instrument type, investors, currency, and staggered maturities in order to reduce unsecured refinancing risk.

We diversify funding by issuing various types of debt instruments—these include both structured loans and structured notes with returns linked to interest rates, currencies, equities, commodities, or related indices. We issue structured loans and structured notes in order to increase the diversity of our debt instruments. We typically hedge the returns we are obliged to pay with derivatives and/or the underlying assets to obtain funding equivalent to our unsecured long-term debt.

11

3.1 Short-Term Unsecured Debt

Our short-term unsecured debt consists of short-term bank borrowings (including long-term bank borrowings maturing within one year), other loans, commercial paper, deposit at banking entities, certificates of deposit and debt securities maturing within one year. Deposits at banking entities and certificates of deposit comprise customer deposits and certificates of deposit of our banking subsidiaries. Short-term unsecured debt includes the current portion of long-term unsecured debt.

The following table presents an analysis of our short-term unsecured debt by type of financial liability as of March 31, 2018 and September 30, 2018.

3.2 Long-Term Unsecured Debt

We meet our long-term capital requirements and also achieve both cost-effective funding and an appropriate maturity profile by routinely funding through long-term debt and diversifying across various maturities and currencies.

Our long-term unsecured debt includes senior and subordinated debt issued through U.S. registered shelf offerings and our U.S. registered medium-term note programs, our Euro medium-term note programs, registered shelf offerings in Japan and various other debt programs.

As a globally competitive financial services group in Japan, we have access to multiple global markets and major funding centers. The Company, Nomura Securities Co. Ltd., Nomura Europe Finance N.V., Nomura Bank International plc, and Nomura International Funding Pte. Ltd. are the main group entities that borrow externally, issue debt instruments and engage in other funding activities. By raising funds to match the currencies and liquidities of our assets or by using foreign exchange swaps as necessary, we pursue optimization of our funding structures.

We use a wide range of products and currencies to ensure that our funding is efficient and well diversified across markets and investor types. Our unsecured senior debt is mostly issued without financial covenants, such as covenants related to adverse changes in our credit ratings, cash flows, results of operations or financial ratios, which could trigger an increase in our cost of financing or accelerate repayment of the debt.

The following table presents an analysis of our long-term unsecured debt by type of financial liability as of March 31, 2018 and September 30, 2018.

12

3.3 Maturity Profile

We also seek to maintain an average maturity for our plain vanilla debt securities and borrowings greater than or equal to three years. A significant amount of our structured loans and structured notes are linked to interest rates, currencies, equities, commodities, or related indices. These maturities are evaluated based on internal models and monitored by Global Treasury. Where there is a possibility that these may be called prior to their scheduled maturity date, maturities are based on our internal stress option adjusted model. The model values the embedded optionality under stress market conditions in order to determine when the debt securities or borrowings are likely to be called.

3.4 Secured Funding

We typically fund our trading activities through secured borrowings, repurchase agreements and Japanese “Gensaki Repo” transactions. We believe such funding activities in the secured markets are more cost-efficient and less credit-rating sensitive than financing in the unsecured market. Our secured funding capabilities depend on the quality of the underlying collateral and market conditions. While we have shorter term secured financing for highly liquid assets, we seek longer terms for less liquid assets. We also seek to lower the refinancing risks of secured funding by transacting with a diverse group of global counterparties and delivering various types of securities collateral. In addition, we reserve an appropriate level of liquidity portfolio for the refinancing risks of secured funding maturing in the short term for less liquid assets. For more detail of secured borrowings and repurchase agreements, see Note 5 “Collateralized transactions” in our consolidated financial statements.

4. Management of Credit Lines to Nomura Group Entities

We maintain and expand credit lines to Nomura Group entities from other financial institutions to secure stable funding. We ensure that the maturity dates of borrowing agreements are distributed evenly throughout the year in order to prevent excessive maturities in any given period.

5. Implementation of Liquidity Stress Tests

We maintain our liquidity portfolio and monitor the sufficiency of our liquidity based on an internal model which simulates changes in cash outflow under specified stress scenarios to comply with our above mentioned liquidity management policy.

We assess the liquidity requirements of the Nomura Group under various stress scenarios with differing levels of severity over multiple time horizons. We evaluate these requirements under Nomura-specific and broad market-wide events, including potential credit rating downgrades at the Company and subsidiary levels. We call this risk analysis our Maximum Cumulative Outflow (“MCO”) framework.

The MCO framework is designed to incorporate the primary liquidity risks for Nomura and models the relevant future cash flows in the following two primary scenarios:

We assume that Nomura will not be able to liquidate assets or adjust its business model during the time horizons used in each of these scenarios. The MCO framework therefore defines the amount of liquidity required to be held in order to meet our expected liquidity needs in a stress event to a level we believe appropriate based on our liquidity risk appetite.

As of September 30, 2018, our liquidity portfolio exceeded net cash outflows under the stress scenarios described above.

We constantly evaluate and modify our liquidity risk assumptions based on regulatory and market changes. The model we use in order to simulate the impact of stress scenarios includes the following assumptions:

13

6. Contingency Funding Plan

We have developed a detailed contingency funding plan to integrate liquidity risk control into our comprehensive risk management strategy and to enhance the quantitative aspects of our liquidity risk control procedures. As a part of our Contingency Funding Plan (“CFP”), we have developed an approach for analyzing and quantifying the impact of any liquidity crisis. This allows us to estimate the likely impact of both Nomura-specific and market-wide events; and specifies the immediate action to be taken to mitigate any risk. The CFP lists details of key internal and external parties to be contacted and the processes by which information is to be disseminated. This has been developed at a legal entity level in order to capture specific cash requirements at the local level—it assumes that our parent company does not have access to cash that may be trapped at a subsidiary level due to regulatory, legal or tax constraints. We periodically test the effectiveness of our funding plans for different Nomura-specific and market-wide events. We also have access to central banks including, but not exclusively, the Bank of Japan, which provide financing against various types of securities. These operations are accessed in the normal course of business and are an important tool in mitigating contingent risk from market disruptions.

Liquidity Regulatory Framework

In 2008, the Basel Committee published “Principles for Sound Liquidity Risk Management and Supervision.” To complement these principles, the Committee has further strengthened its liquidity framework by developing two minimum standards for funding liquidity. These standards have been developed to achieve two separate but complementary objectives.

The first objective is to promote short-term resilience of a financial institution’s liquidity risk profile by ensuring that it has sufficient high-quality liquid assets to survive a significant stress scenario lasting for 30 days. The Committee developed the Liquidity Coverage Ratio (“LCR”) to achieve this objective.

The second objective is to promote resilience over a longer time horizon by creating additional incentives for financial institutions to fund their activities with more stable sources of funding on an ongoing basis. The Net Stable Funding Ratio (“NSFR”) has a time horizon of one year and has been developed to provide a sustainable maturity structure of assets and liabilities.

These two standards are comprised mainly of specific parameters which are internationally “harmonized” with prescribed values. Certain parameters, however, contain elements of national discretion to reflect jurisdiction-specific conditions.

In Japan, the regulatory notice on the LCR, based on the international agreement issued by the Basel Committee with necessary national revisions, was published by Financial Services Agency (on October 31, 2014). The notices have been implemented since the end of March 2015 with phased-in minimum standards. Average of Nomura’s LCRs for the three months ended September 30, 2018 was 191.1%, and Nomura was compliant with requirements of the above notices. As for the NSFR, it is not yet implemented in Japan.

Cash Flows

Cash, cash equivalents, restricted cash and restricted cash equivalents’ balance as of September 30, 2017 and as of September 30, 2018 were ¥2,667.8 billion and ¥2,975.9 billion, respectively. Cash flows from operating activities for the six months ended September 30, 2017 outflows of ¥312.1 billion due primarily to a decrease in Securities purchased under agreements to resell, net of securities sold under agreements to repurchase and for the comparable period in 2018 were inflows of ¥108.9 billion due primarily to an increase in Securities borrowed, net of securities loaned. Cash flows from investing activities for the six months ended September 30, 2017 were inflows of ¥74.7 billion due primarily to a decrease in Other, net and for the comparable period in 2018 were inflows of ¥28.4 billion due primarily to a decrease in non-trading debt securities, net. Cash flows from financing activities for the six months ended September 30, 2017 were inflows of ¥359.0 billion due primarily to an increase in Long-term borrowings and for the comparable period in 2018 were inflows of ¥414.5 billion due primarily to an increase in Long-term borrowings.

Balance Sheet and Financial Leverage

Total assets as of September 30, 2018, were ¥45,360.3 billion, an increase of ¥5,016.4 billion compared with ¥40,343.9 billion as of March 31, 2018, primarily due to an increase in Securities purchased under agreements to resell. Total liabilities as of September 30, 2018, were ¥42,514.3 billion, an increase of ¥4,970.2 billion compared with ¥37,544.1 billion as of March 31, 2018, primarily due to an increase in Securities sold under agreements to repurchase. NHI shareholders’ equity as of September 30, 2018, was ¥2,800.8 billion, an increase of ¥51.5 billion compared with ¥2,749.3 billion as of March 31, 2018, primarily due to an increase in Accumulated other comprehensive income.

Due to the changes in our accounting policy which Nomura adopted on April 1, 2018, certain reclassifications of previously reported amounts have been made to conform to the current year presentation. Please refer to Item 4. Financial Information, 1. Consolidated Financial Statements, Note 1. “Basis of Accounting” for further details.

We seek to maintain sufficient capital at all times to withstand losses due to extreme market movements. The EMB is responsible for implementing and enforcing capital policies. This includes the determination of our balance sheet size and required capital levels. We continuously review our equity capital base to ensure that it can support the economic risk inherent in our business. There are also regulatory requirements for minimum capital of entities that operate in regulated securities or banking businesses.

As leverage ratios are commonly used by other financial institutions similar to us, we voluntarily provide a Leverage ratio and Adjusted leverage ratio primarily for benchmarking purposes so that users of our annual report can compare our leverage against other financial institutions. Adjusted leverage ratio is a non-GAAP financial measure that Nomura considers to be a useful supplemental measure of leverage.

The following table sets forth NHI shareholders’ equity, total assets, adjusted assets and leverage ratios:

Total assets increased by 12.4% reflecting primarily an increase in Securities purchased under agreements to resell. NHI shareholders’ equity increased by 1.9% primarily due to an increase in Accumulated other comprehensive income. As a result, our leverage ratio rose from 14.7 times as of March 31, 2018 to 16.2 times as of September 30, 2018.

Adjusted assets increased primarily due to an increase in Trading assets. As a result, our adjusted leverage ratio rose from 8.8 times as of March 31, 2018 to 9.1 times as of September 30, 2018.

Consolidated Regulatory Capital Requirements

The FSA established the “Guideline for Financial Conglomerates Supervision” (“Financial Conglomerates Guideline”) in June 2005 and set out the rules on consolidated regulatory capital. We started monitoring our consolidated capital adequacy ratio in accordance with the Financial Conglomerates Guideline from April 2005.

The Company has been assigned by the FSA as a Final Designated Parent Company who must calculate a consolidated capital adequacy ratio according to the Capital Adequacy Notice on Final Designated Parent Company in April 2011. Since then, we have been calculating our consolidated capital adequacy ratio according to the Capital Adequacy Notice on Final Designated Parent Company. The Capital Adequacy Notice on Final Designated Parent Company has been revised to be in line with Basel 2.5 and Basel III since then. We have calculated a Basel III-based consolidated capital adequacy ratio from the end of March 2013. Basel 2.5 includes significant change in calculation method of market risk and Basel III includes redefinition of capital items for the purpose of requiring higher quality of capital and expansion of the scope of credit risk-weighted assets calculation.

In accordance with Article 2 of the Capital Adequacy Notice on Final Designated Parent Company, our consolidated capital adequacy ratio is currently calculated based on the amounts of common equity Tier 1 capital, Tier 1 capital (sum of common equity Tier 1 capital and additional Tier 1 capital), total capital (sum of Tier 1 capital and Tier 2 capital), credit risk-weighted assets, market risk and operational risk. As of September 30, 2018, our common equity Tier 1 capital ratio (common equity Tier 1 capital divided by risk-weighted assets) was 17.00%, Tier 1 capital ratio (Tier 1 capital divided by risk-weighted assets) was 18.11% and consolidated capital adequacy ratio (total capital divided by risk-weighted assets) was 18.52% and we were in compliance with the requirement for each ratio set out in the Capital Adequacy Notice on Final Designated Parent Company (required level as of September 30, 2018 was 6.79% for common equity Tier 1 capital ratio, 8.29% for Tier 1 capital ratio and 10.29% for consolidated capital adequacy ratio).

The following table presents the Company’s consolidated capital adequacy ratios as of September 30, 2018.

Consolidated Leverage Ratio Requirements

In March 2015, the FSA set out requirements for the calculation and disclosure of a consolidated leverage ratio, through amendments to revising “Specification of items which a final designated parent company should disclose on documents to show the status of its sound management” (2010 FSA Regulatory Notice No. 132; “Notice on Pillar 3 Disclosure”) and the publication of “Consolidated Leverage Ratio prescribed by Commissioner of Financial Services Agency in accordance with Article 3, paragraph 1 of Pillar 3 Notice” (2015 FSA Regulatory Notice No. 11; “Notice on Consolidated Leverage Ratio”). We started calculating and disclosing a consolidated leverage ratio from March 31, 2015 in accordance with the Notice on Pillar 3 Disclosure and Notice on Consolidated Leverage Ratio. Management receives and reviews this consolidated leverage ratio on a regular basis. As of September 30, 2018, our consolidated leverage ratio was 4.45%.
