PRESENTATION OF FINANCIAL AND OTHER INFORMATION

In this annual report, “we,” “us,” and “our” refer to Mizuho Financial Group, Inc. and, unless the context indicates otherwise, its consolidated subsidiaries. “Mizuho Financial Group” refers to Mizuho Financial Group, Inc. Furthermore, unless the context indicates otherwise, these references are intended to refer to us as if we had been in existence in our current form for all periods referred to herein.

On July 1, 2013, a merger between the former Mizuho Bank, Ltd. and the former Mizuho Corporate Bank, Ltd. came into effect with the former Mizuho Corporate Bank as the surviving entity, which was renamed Mizuho Bank upon the merger. In this annual report, “Mizuho Bank” refers to the post-merger entity, while the “former Mizuho Bank” and the “former Mizuho Corporate Bank” refer to pre-merger Mizuho Bank and pre-merger Mizuho Corporate Bank, respectively.

In this annual report, “our principal banking subsidiaries” refer to Mizuho Bank and Mizuho Trust & Banking Co., Ltd. (or with respect to references as of a date, or for periods ending, before July 1, 2013, to the former Mizuho Bank, the former Mizuho Corporate Bank and Mizuho Trust & Banking).

In this annual report, references to “U.S. dollars,” “dollars” and “$” refer to the lawful currency of the United States and those to “yen” and “¥” refer to the lawful currency of Japan.

In this annual report, yen figures and percentages have been rounded to the figures shown. However, in some cases, figures presented in tables have been adjusted to match the sum of the figures with the total amount, and such figures may also be referred to in the related text. In addition, yen figures and percentages in “Item 3.A. Key Information—Selected Financial Data—Japanese GAAP Selected Consolidated Financial Information” and others that are specified have been truncated to the figures shown.

Our fiscal year end is March 31. References to years not specified as being fiscal years are to calendar years.

Unless otherwise specified, for purposes of this annual report, we have presented our financial information in accordance with accounting principles generally accepted in the United States, or U.S. GAAP. Unless otherwise stated or the context otherwise requires, all amounts in our financial statements are expressed in yen.

We usually hold the ordinary general meeting of shareholders of Mizuho Financial Group in June of each year in Chiyoda-ku, Tokyo.

FORWARD-LOOKING STATEMENTS

We may from time to time make written or oral forward-looking statements. Written forward-looking statements may appear in documents filed with the Securities and Exchange Commission, including this annual report, and other reports to shareholders and other communications.

The U.S. Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking information to encourage companies to provide prospective information about themselves. We rely on this safe harbor in making these forward-looking statements.

This annual report contains forward-looking statements regarding the intent, belief, current expectations and targets of our management with respect to our financial condition and future results of operations. In many cases, but not all, we use such words as “aim,” “anticipate,” “believe,” “endeavor,” “estimate,” “expect,” “intend,” “may,” “plan,” “probability,” “project,” “risk,” “seek,” “should,” “strive,” “target” and similar expressions in relation to us or our management to identify forward-looking statements. You can also identify forward-looking

3

statements by discussions of strategy, plans or intentions. These statements reflect our current views with respect to future events and are subject to risks, uncertainties and assumptions. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, our actual results may vary materially from those we currently anticipate. Potential risks and uncertainties include, without limitation, the following:

• incurrence of significant credit-related costs;

• declines in the value of our securities portfolio, including as a result of the declines in stock markets and the impact of the dislocation in the global financial markets;

• changes in interest rates;

• foreign exchange rate fluctuations;

• decrease in the market liquidity of our assets;

• revised assumptions or other changes related to our pension plans;

• a decline in our deferred tax assets;

• the effect of financial transactions entered into for hedging and other similar purposes;

• failure to maintain required capital adequacy ratio levels;

• downgrades in our credit ratings;

• our ability to avoid reputational harm;

• our ability to implement our Medium-term Business Plan and other strategic initiatives and measures effectively;

• the effectiveness of our operation, legal and other risk management policies;

• the effect of changes in general economic conditions in Japan and elsewhere; and

• amendments and other changes to the laws and regulations that are applicable to us.

Our forward-looking statements are not guarantees of future performance and involve risks and uncertainties. Actual results may differ from those in the forward-looking statements as a result of various factors. We identify in this annual report in “Item 3.D. Key Information—Risk Factors,” “Item 4.B. Information on the Company—Business Overview,” “Item 5. Operating and Financial Review and Prospects” and elsewhere, some, but not necessarily all, of the important factors that could cause these differences.

We do not intend to update our forward-looking statements. We are under no obligation, and disclaim any obligation, to update or alter our forward-looking statements, whether as a result of new information, future events or otherwise.

Notes:

(1) For the fiscal year ended March 31, 2012, certain items in expenses regarding stock transfer agency business and pension management business, which had been recorded as “General and administrative expenses” by Mizuho Trust & Banking until the previous fiscal year, have been included in “Net fee and commission income” as “Fee and commission expenses,” and reclassification of prior year figures has been made accordingly.

(2) Includes refund of income taxes.

(3) Yen amounts are expressed in U.S. dollars at the rate of ¥82.76 = $1.00, ¥82.41 = $1.00, ¥94.16 = $1.00, ¥102.98 = $1.00 and ¥119.96 = $1.00 for the fiscal years ended March 31, 2011, 2012, 2013, 2014 and 2015, respectively. These rates are the noon buying rates on the respective fiscal year-end dates in New York City for cable transfers in yen as certified for customs purposes by the Federal Reserve Bank of New York.

(4) In June 2015, we declared and paid annual dividends of ¥7.5 per share of common stock and ¥20 per share of eleventh series class XI preferred stock for the fiscal year ended March 31, 2015.

(5) On July 11, 2013, we acquired and subsequently cancelled all of the thirteenth series class XIII preferred stock. Accordingly, cash dividend payments related to the thirteenth series class XIII preferred stock for the fiscal year ended March 31, 2014 were not be made during the fiscal year ending March 31, 2015.

(6) Bills discounted refer to a form of financing in Japan under which promissory notes obtained by corporations through their regular business activities are purchased by banks prior to their payment dates at a discount based on prevailing interest rates.

(7) Includes negotiable certificates of deposit.

(8) Risk-adjusted capital data are calculated on a Basel II basis until the fiscal year ended March 31, 2012, and on a Basel III basis from the fiscal year ended March 31, 2013. We adopted the advanced internal ratings-based approach (the “AIRB approach”) for the calculation of risk-weighted assets associated with credit risk from the fiscal year ended March 31, 2009. We also adopted the advanced measurement approach (the “AMA”) for the calculation of operational risk from the fiscal year ended March 31, 2010. For more details on capital adequacy requirements set by the Bank for International Settlements (“BIS”), and the guideline implemented by the Financial Services Agency in compliance thereto, see “Item 5. Operating and Financial Review and Prospects—Capital Adequacy.”

There are certain differences between U.S. GAAP and Japanese GAAP. The differences between U.S. GAAP and Japanese GAAP applicable to us primarily relate to the accounting for derivative financial instruments and hedging activities, investments, loans, allowances for loan losses and off-balance-sheet instruments, premises and equipment, land revaluation, business combinations, pension liabilities, consolidation of variable interest entities, deferred taxes and foreign currency translation. See “Item 5. Operating and Financial Review and Prospects—Reconciliation with Japanese GAAP.”

3.D. Risk Factors

Investing in our securities involves a high degree of risk. You should carefully consider the risks described below as well as the other information in this annual report, including our consolidated financial statements and related notes, “Item 5. Operating and Financial Review and Prospects,” “Item 11. Quantitative and Qualitative Disclosures about Market Risk” and “Selected Statistical Data.”

Our business, financial condition and operating results could be materially adversely affected by any of the factors discussed below. The trading price of our securities could decline due to any of these factors. This annual report also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including the risks faced by us described below and elsewhere in this annual report. See “Forward-Looking Statements.”

10

Risks Relating to Our Business

We may incur significant credit-related and other costs in the future due to problem loans.

We are the primary bank lender for a large number of our corporate customers, and the amount of our loans and other claims to each of our major customers is significant. In addition, while we have made efforts to diversify our credit exposure along industry lines, the proportion of credit exposure to customers in the construction and real estate, banks and other financial institutions, and wholesale and retail industries is relatively high. We manage our credit portfolio by regularly monitoring the credit profile of each of our customers, the progress made on restructuring plans and credit exposure concentrations in particular industries or corporate groups, and we also utilize credit derivatives for hedging and credit risk mitigation purposes. In addition, we regularly assess the value of collateral and guarantees. However, depending on trends in the domestic and global economic environment, the business environment in particular industries and other factors, the amount of our problem loans and other claims could increase significantly, including as a result of the deterioration in the credit profile of customers for which we are the primary bank lender, other major customers or customers belonging to industries to which we have significant credit exposure, and the value of collateral and guarantees could decline. There can be no assurance that credit-related and other costs will not increase in the future as a result of the foregoing or otherwise.

Our equity investment portfolio exposes us to market risks that could adversely affect our financial condition and results of operations.

We hold substantial investments in marketable equity securities, mainly common stock of Japanese listed companies. In addition to the partial hedges that we apply as we deem necessary in recent years, we sold a portion of such investments, and we may make further sales in the future. However, significant declines in Japanese stock prices in the future would lead to unrealized losses, losses on impairment and losses from sales of equity securities which could have a material adverse effect on our financial condition and results of operations. In addition, net unrealized gains and losses on such investments, based on Japanese GAAP, are taken into account when calculating the amount of capital for purposes of the calculation of our capital adequacy ratios, and as a result, a decline in the value of such investments would negatively affect such ratios. Accordingly, our financial condition and results of operations could be materially and adversely affected.

Changes in interest rates could adversely affect our financial condition and results of operations.

We hold a significant amount of bonds, consisting mostly of Japanese government bonds, and other instruments primarily for the purpose of investment. As a result of such holdings, an increase in interest rates, primarily yen interest rates, could lead to unrealized losses of bonds or losses from sales of bonds. In addition, due mainly to differences in maturities between financial assets and liabilities, changes in interest rates could have an adverse effect on our average interest rate spread. We manage interest rate risk under our risk management policies, which provide for adjustments in the composition of our bond portfolio and the utilization of derivatives and other hedging methods to reduce our exposure to interest rate risk. However, in the event of significant changes in interest rates, including as a result of a change in Japanese monetary policy, increased sovereign risk due to deterioration of public finances and market trends, our financial condition and results of operations could be materially and adversely affected.

Our financial condition and results of operations could be adversely affected by foreign exchange rate fluctuations.

A portion of our assets and liabilities is denominated in foreign currencies, mainly the U.S. dollar. The difference between the amount of assets and liabilities denominated in foreign currencies leads to foreign currency translation gains and losses in the event of fluctuations in foreign exchange rates. Although we hedge a portion of our exposure to foreign exchange rate fluctuation risk, our financial condition and results of operations could be materially and adversely affected if future foreign exchange rate fluctuations significantly exceed our expectations.

11

We may incur further losses relating to decreases in the market liquidity of assets that we hold.

The market liquidity of the various marketable assets that we hold may decrease significantly due to turmoil in financial markets and other factors, and the value of such assets could decline as a result. If factors such as turmoil in global financial markets or the deterioration of economic or financial conditions cause the market liquidity of our assets to decrease significantly, our financial condition and results of operations could be materially and adversely affected.

Our pension-related costs could increase as a result of revised assumptions or changes in our pension plans.

Our pension-related costs and projected benefit obligations are calculated based on assumptions regarding projected returns on pension plan assets and various actuarial assumptions relating to the plans. If actual results differ from our assumptions or we revise our assumptions in the future, due to changes in the stock markets, interest rate environment or otherwise, our pension-related costs and projected benefit obligations could increase. In addition, any future changes to our pension plans could also lead to increases in our pension-related costs and projected benefit obligations. As a result, our financial condition and results of operations could be materially and adversely affected.

A decrease in deferred tax assets, net of valuation allowance, due to a change in our estimation of future taxable income or change in Japanese tax policy could adversely affect our financial condition and results of operations.

We recorded deferred tax assets, net of valuation allowance, based on a reasonable estimation of future taxable income in accordance with applicable accounting standards. Our financial condition and results of operations could be materially and adversely affected if our deferred tax assets decrease due to a change in our estimation of future taxable income, a change in tax rate as a result of tax system revisions or other factors. Because we consider the sale of available-for-sale securities to be a qualifying tax-planning strategy, turmoil in financial markets such as significant declines in stock prices could lead to a decrease in our estimated future taxable income.

Financial transactions entered into for hedging and other similar purposes could adversely affect our financial condition and results of operations.

The accounting and valuation methods applied to credit and equity derivatives and other financial transactions that we enter into for hedging and credit risk mitigation purposes are not always consistent with the accounting and valuation methods applied to the assets that are being hedged. Consequently, in some cases, due to changes in the market or otherwise, losses related to such financial transactions during a given period may adversely affect net income, while the corresponding increases in the value of the hedged assets do not have an effect on net income for such period. As a result, our financial condition and results of operations could be materially and adversely affected during the period.

Failure to maintain capital adequacy ratios above minimum required levels, as a result of the materialization of risks or regulatory changes, could result in restrictions on our business activities.

We endeavor to maintain sufficient levels of capital adequacy ratios, which are calculated pursuant to standards set forth by Japan’s Financial Services Agency and based on Japanese GAAP, taking into account our plans for investments in risk-weighted assets, the efficiency of our capital structure and other factors. However, our capital adequacy ratios could decline in the future, including as a result of the materialization of any of the risks enumerated in these “Risk Factors” and changes to the methods we use to calculate capital adequacy ratios. Also, there are regulatory adjustments such as goodwill and other intangibles, deferred tax assets, investments in the capital of banking, financial and insurance entities etc., that are deducted from our regulatory capital under certain conditions. Our or our banking subsidiaries’ regulatory capital and capital adequacy ratios could decline due to such regulations.

12

In addition, if the framework set by the Basel Committee on Banking Supervision, upon which the Financial Services Agency’s rules concerning banks’ capital adequacy ratios are based, is changed or if the Financial Services Agency otherwise changes its banking regulations, we might not be able to meet the minimum regulatory requirements for capital adequacy ratios. For example, in December 2010, the Basel Committee on Banking Supervision issued its Basel III rules text, which presents the details of global regulatory standards on bank capital adequacy and liquidity. In March 2012, the Financial Services Agency published revisions to its capital adequacy guidelines which generally reflect rules in the Basel III text and became effective as of March 31, 2013. Furthermore, the Financial Stability Board (the “FSB”) named us as one of 30 global systemically important banks (“G-SIBs”) in November 2014. As a G-SIB, we will be subject to additional capital requirements. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations of Mizuho Financial Group—Capital Adequacy” and “Supervision and Regulation—Capital Adequacy.” The group of G-SIBs will be updated annually and published by the FSB each November.

If the capital adequacy ratios of us and our banking subsidiaries fall below specified levels, the Financial Services Agency could require us to take corrective actions, including, depending on the level of deficiency, submission of an improvement plan that would strengthen our capital base, a reduction of our total assets or a suspension of a portion of our business operations. In addition, some of our banking subsidiaries are subject to capital adequacy regulations in foreign jurisdictions such as the United States, and our business could be adversely affected if their capital adequacy ratios fall below specified levels.

Downgrades in our credit ratings could have negative effects on our funding costs and business operations.

Credit ratings are assigned to Mizuho Financial Group, our banking subsidiaries and a number of our other subsidiaries by major domestic and international credit rating agencies. The credit ratings are based on information furnished by us or obtained by the credit rating agencies from independent sources and are also influenced by credit ratings of Japanese government bonds and general views regarding the Japanese financial system as a whole. The credit ratings are subject to revision, suspension or withdrawal by the credit rating agencies at any time. A downgrade in our credit ratings could result in, among other things, the following:

• increased funding costs and other difficulties in raising funds;

• the need to provide additional collateral in connection with financial market transactions; and

• the termination or cancellation of existing agreements.

As a result, our business, financial condition and results of operations could be materially and adversely affected.

For example, the additional collateral requirement in connection with our derivative contracts, absent other changes, assuming a downgrade occurred on March 31, 2015, would have been approximately $33 million for a one-notch downgrade and approximately $109 million for a two-notch downgrade.

Our business will be adversely affected if we encounter difficulties in raising funds.

We rely principally on deposits and bonds as our funding sources. In addition, we also raise funds in the financial markets. Our efforts to maintain stable funding, such as setting maximum limits on financial market funding and monitoring our liquidity position to apply appropriate funding policies, may not be sufficient to prevent significant increases in our funding costs or, in the case mainly of foreign currencies, cash flow problems if we encounter difficulties in attracting deposits or otherwise raising funds. Such difficulties could result, among other things, from any of the following:

• adverse developments with respect to our financial condition and results of operations;

• downgrading of our credit ratings or damage to our reputation; or

13

• a reduction in the size and liquidity of the debt markets due for example to the decline in the domestic and global economy, concerns regarding the financial system or turmoil in financial markets and other factors.

Our Medium-term Business Plan and other strategic initiatives and measures may not result in the anticipated outcome.

We have been implementing strategic initiatives and measures in various areas. In February 2013, we announced our new Medium-term Business Plan for the three fiscal years ending March 31, 2016, in which we set forth various strategic initiatives and measures and also established a number of key target figures that we aim to achieve by the end of the fiscal year ending March 31, 2016.

However, we may not be successful in implementing such initiatives and measures, or even if we are successful in implementing them, the implementation of such initiatives and measures may not have their anticipated effects. In addition, we may not be able to meet the key target figures announced in the Medium-term Business Plan due to these or other factors, including, but not limited to, differences in the actual economic environment compared to our assumptions underlying the Medium-term Business Plan, as well as the risks enumerated in these “Risk Factors.”

We will be exposed to new or increased risks as we expand the range of our products and services.

We offer a broad range of financial services, including banking, trust, securities and other services. As the needs of our customers become more sophisticated and broader in scope, and as the Japanese financial industry continues to be deregulated, we have been entering into various new areas of business, including through various business and equity alliances, which expose us to new risks. While we have developed and intend to maintain risk management policies that we believe are appropriate to address such risks, if a risk materializes in a manner or to a degree outside of our expectations, our business, financial condition and results of operations could be materially and adversely affected.

We are subject to various laws and regulations, and violations could result in penalties and other regulatory actions.

Our business and employees in Japan are subject to various laws and regulations, including those applicable to financial institutions as well as general laws applicable to our business activities, and we are under the regulatory oversight of the Financial Services Agency. Our businesses outside of Japan are also subject to the laws and regulations of the jurisdictions in which they operate and are subject to oversight by the regulatory authorities of those jurisdictions.

Our compliance and legal risk management structures are designed to prevent violations of such laws and regulations, but they may not be effective in preventing all future violations. Future violations of laws and regulations could result in regulatory action and harm our reputation, and our business, financial condition and results of operations could be materially and adversely affected.

Employee errors and misconduct could subject us to losses and reputational harm.

Because we process a large number of transactions in a broad range of businesses, we are subject to the risk of various operational errors and misconduct, including those caused by employees. Our measures to reduce employee errors, including establishment of operational procedures, regular reviews regarding compliance with these procedures, employee training and automation of our operations, may not be effective in preventing all employee errors and misconduct. Significant operational errors and misconduct in the future could result in losses, regulatory actions or harm to our reputation. As a result, our business, financial condition and results of operations could be materially and adversely affected.

14

Problems relating to our information technology systems could significantly disrupt our business operations.

We depend significantly on information technology systems with respect to almost all aspects of our business operations. Our information technology systems network, including those relating to bank accounting and cash settlement systems, interconnects our branches and other offices, our customers and various clearing and settlement systems located worldwide. Our efforts to sustain stable daily operations and development of contingency plans for unexpected events, including the implementation of backup and redundancy measures, may not be effective in preventing significant disruptions to our information technology systems caused by, among other things, human error, accidents, hacking, computer viruses, cyber attacks, and development and renewal of computer systems. In the event of any such disruption, our business, financial condition and results of operations could be materially and adversely affected due to disruptions in our business operations, liability to customers and others, regulatory actions or harm to our reputation.

Our reputation could be harmed and we may be subject to liabilities and regulatory actions if we are unable to protect personal and other confidential information.

We handle various confidential or non-public information, including those of our individual and corporate customers, in the ordinary course of our business. The information management policies we maintain and enforce to prevent information leaks and improper access to such information, including those designed to meet the strict requirements of the Personal Information Protection Act of Japan, may not be effective in preventing all such problems. Leakage of important information in the future could result in liabilities and regulatory actions and may also lead to significant harm to our reputation. As a result, our business, financial condition and results of operations could be materially and adversely affected.

Our business would be harmed if we are unable to attract and retain skilled employees.

Many of our employees possess skills and expertise that are important to maintain our competitiveness and to operate our business efficiently. We may not be successful in attracting and retaining sufficient skilled employees through our hiring efforts and training programs aimed to maintain and enhance the skills and expertise of our employees, in which event our competitiveness and efficiency could be significantly impaired. As a result, our business, financial condition and results of operations could be materially and adversely affected.

Our failure to establish, maintain and apply adequate internal controls over financial reporting could negatively impact investor confidence in the reliability of our financial statements.

As a New York Stock Exchange-listed company and an SEC registrant, we have developed disclosure controls and procedures and internal control over financial reporting pursuant to the requirements of the Sarbanes-Oxley Act of 2002 and rules and regulations of the SEC promulgated pursuant thereto. Our management reports on, and our independent registered public accounting firm attests to, the effectiveness of our internal controls over financial reporting, as required, in our annual report on Form 20-F. In addition, our management is required to report on our internal control over financial reporting, and our independent registered public accounting firm is required to provide its opinion concerning the report of our management, in accordance with the Financial Instruments and Exchange Act of Japan. To the extent any issues are identified through the foregoing processes, there can be no assurance that we will be able to address them in a timely manner or at all. Furthermore, even if our management concludes that our internal control over financial reporting are effective, our independent registered public accounting firm may still be unable to issue a report that concludes that our internal control over financial reporting are effective. In either case, we may lose investor confidence in the reliability of our financial statements.

15

We are subject to risk of litigation and other legal proceedings.

As a financial institution engaging in banking and other financial businesses in and outside of Japan, we are subject to the risk of litigation for damages and other legal proceedings in the ordinary course of our business. Adverse developments related to future legal proceedings could have a material adverse effect on our financial condition and results of operations.

Our risk management policies and procedures may not adequately address unidentified or unanticipated risks.

We devote significant resources to strengthening our risk management policies and procedures. Despite this, and particularly in light of the rapid evolution of our operations, our policies and procedures designed to identify, monitor and manage risks may not be fully effective. Some of our methods of managing risks are based upon our use of observed historical market behavior. As a result, these methods may not accurately predict future risk exposures, which could be significantly greater than the historical measures indicate. If our risk management policies and procedures do not function effectively, our financial condition and results of operations could be materially and adversely affected.

Transactions with counterparties in Iran and other countries designated by the U.S. Department of State as state sponsors of terrorism may lead some potential customers and investors to avoid doing business with us or investing in our securities or have other adverse effects.

U.S. law generally prohibits U.S. persons from doing business with countries designated by the U.S. Department of State as state sponsors of terrorism (the “Designated Countries”), which currently includes Iran, Sudan and Syria and we maintain policies and procedures to comply with U.S. law. Our non-U.S. offices engage in transactions relating to the Designated Countries on a limited basis and in compliance with applicable laws and regulations, including trade financing with respect to our customers’ export or import transactions and maintenance of correspondent banking accounts. In addition, we maintain a representative office in Iran. We do not believe our operations relating to the Designated Countries are material to our business, financial condition or results of operations. We maintain policies and procedures to ensure compliance with applicable Japanese and U.S. laws and regulations.

The laws and regulations applicable to dealings involving the Designated Countries are subject to further strengthening or changes. If the U.S. government considers that our compliance measures are inadequate, we may be subject to regulatory action which could materially and adversely affect our business. In addition, we may become unable to retain or acquire customers or investors in our securities, or our reputation may suffer, potentially having adverse effects on our business or the price of our securities.

Our common stock may be subject to dilution as a result of conversion of our convertible preferred stock.

Holders of our eleventh series class XI preferred stock may convert their shares to common stock by requesting us to acquire such shares and issue or transfer common stock to them at any time between July 1, 2008 and June 30, 2016, with mandatory conversion on July 1, 2016. Due to the dilution of our common stock that occurs as a result of the increase in the number of outstanding shares of common stock upon such conversion, the price of our common stock could decline.

We may be subject to risks related to dividend distributions.

As a holding company, we rely on dividend payments from our banking and other subsidiaries for almost all of our income. As a result of restrictions, such as those on distributable amounts under Japan’s Companies Act, or otherwise, our banking and other subsidiaries may decide not to pay dividends to us. In addition, we may experience difficulty in making, or become unable to make, dividend payments to our shareholders and dividend or interest payments on capital securities issued by our group due to the deterioration of our results of operations

16

and financial condition and/or the restrictions under the Companies Act or due to the strengthening of bank capital regulations. For more information on restrictions to dividend payments under the Companies Act, see “Item 10.B. Additional Information—Memorandum and Articles of Association.”

We may be adversely affected if economic or market conditions in Japan or elsewhere deteriorate.

We conduct business operations in Japan as well as overseas, including in the United States, Europe and Asia. If general economic conditions in Japan or other regions were to deteriorate or if the financial markets become subject to turmoil, we could experience weakness in our business, as well as deterioration in the quality of our assets. Future deterioration in general economic conditions or financial market turmoil could materially and adversely affect our financial condition and results of operations.

Amendments and other changes to the laws and regulations that are applicable to us could have an adverse effect on us.

We are subject to general laws, regulations and accounting rules applicable to our business activities in and outside of Japan. We are also subject to various laws and regulations applicable to financial institutions such as the Banking Act, including capital adequacy requirements, in and outside of Japan. If the laws and regulations that are applicable to us are amended or otherwise changed, such as in a way that restricts us from engaging in business activities that we currently conduct, our business, financial condition and results of operations could be materially and adversely affected.

Intensification of competition in the market for financial services in Japan could have an adverse effect on us.

Ongoing deregulation in Japan has lowered the barriers to entry with respect to the provision of banking, trust, securities and other financial services. While such deregulation has the effect of increasing our own business opportunities, it also allows other major financial groups, foreign financial institutions, non-bank finance companies, government-affiliated entities such as Japan Post Bank and other financial services providers to enter into new business areas or expand existing businesses, resulting in the intensification of competition in the financial services industry. If we are unable to respond effectively to current or future competition, our business, financial condition and results of operations could be adversely affected. In addition, intensifying competition and other factors could lead to reorganization within the financial services industry, and this could have an adverse effect on our competitive position or otherwise adversely affect the price of our securities.

Our business could be significantly disrupted due to natural disasters, accidents or other causes.

Our headquarters, branch offices, information technology centers, computer network connections and other facilities are subject to the risk of damage from natural disasters such as earthquakes and typhoons as well as from acts of terrorism and other criminal acts. In addition, our business could be materially disrupted as a result of an epidemic such as new or reemerging influenza infections. Our business, financial condition and results of operations could be adversely affected if our recovery efforts, including our implementation of contingency plans that we have developed such as establishing back-up offices, are not effective in preventing significant disruptions to our business operations caused by natural disasters and criminal acts. Additionally, massive natural disasters such as the March 2011 Great East Japan Earthquake may have various adverse effects, including a deterioration in economic conditions, declines in the business performance of many of our corporate customers and declines in stock prices. As a result, our financial condition and results of operations could be materially and adversely affected due to an increase in the amount of problem loans and credit-related costs as well as an increase in unrealized losses on, or losses from sales of, equity securities and financial products.

Negative rumors about us could have an adverse effect on us.

Our business depends on maintaining the trust of depositors and other customers and market participants. Negative rumors about us, spread through media coverage, communications between market participants,

17

Internet postings or otherwise, could lead to our customers and market participants believing factually incorrect information about us and harm our reputation. In the event we are unable to dispel such rumors or otherwise restore our reputation, our business, financial condition, results of operations and the price of our securities could be materially and adversely affected.

Risks Related to Owning Our Shares

Rights of shareholders under Japanese law may be more limited than under the law of other jurisdictions.

Our articles of incorporation, our regulations of board of directors and Japan’s Companies Act govern our corporate affairs. Legal principles relating to such matters as the validity of corporate procedures, directors’ and officers’ fiduciary duties and shareholders’ rights may be different from or less clearly defined than those that would apply if we were incorporated in another jurisdiction. For example, under the Companies Act, only holders of 3% or more of the total voting rights or total outstanding shares are entitled to examine our accounting books and records. Shareholders’ rights under Japanese law may not be as extensive as shareholders’ rights under the law of jurisdictions within the United States or other countries. For more information on the rights of shareholders under Japanese law, see “Item 10.B. Additional Information—Memorandum and Articles of Association.”

It may not be possible for investors to effect service of process within the United States upon us or our directors, executive officers or senior management, or to enforce against us or those persons judgments obtained in U.S. courts predicated upon the civil liability provisions of the federal securities laws of the United States.

We are a joint stock corporation incorporated under the laws of Japan. Almost all of our directors, executive officers and senior management reside outside the United States. Many of the assets of us and these persons are located in Japan and elsewhere outside the United States. It may not be possible, therefore, for U.S. investors to effect service of process within the United States upon us or these persons or to enforce, against us or these persons, judgments obtained in the U.S. courts predicated upon the civil liability provisions of the federal securities laws of the United States. We believe that there is doubt as to the enforceability in Japan, in original actions or in actions to enforce judgments of U.S. courts, of claims predicated solely upon the federal securities laws of the United States.

Risks Related to Owning Our ADSs

As a holder of ADSs, you have fewer rights than a shareholder and you must act through the depositary to exercise these rights.

The rights of our shareholders under Japanese law to take actions such as voting their shares, receiving dividends and distributions, bringing derivative actions, examining our accounting books and records and exercising appraisal rights are available only to shareholders of record. Because the depositary, through its custodian, is the record holder of the shares underlying the ADSs, a holder of ADSs may not be entitled to the same rights as a shareholder. In your capacity as an ADS holder, you are not able to bring a derivative action, examine our accounting books and records or exercise appraisal rights, except through the depositary.

Foreign exchange rate fluctuations may affect the U.S. dollar value of our ADSs and dividends payable to holders of our ADSs.

Market prices for our ADSs may fall if the value of the yen declines against the U.S. dollar. In addition, the U.S. dollar amount of cash dividends and other cash payments made to holders of our ADSs would be reduced if the value of the yen declines against the U.S. dollar.

ITEM 4. INFORMATION ON THE COMPANY

4.A. History and Development of the Company

The Mizuho Group

The Mizuho group was created on September 29, 2000 through the establishment of Mizuho Holdings, Inc. as a holding company of our three predecessor banks, The Dai-Ichi Kangyo Bank, The Fuji Bank and The Industrial Bank of Japan. On October 1, 2000, the respective securities subsidiaries of the predecessor banks merged to form Mizuho Securities Co., Ltd. and the respective trust bank subsidiaries merged on the same date to form Mizuho Trust & Banking.

A further major step in the Mizuho group’s development occurred in April 2002 when the operations of our three predecessor banks were realigned through a corporate split and merger process under Japanese law into a wholesale banking subsidiary, the former Mizuho Corporate Bank, and a banking subsidiary serving primarily retail and small and medium-sized enterprise customers, the former Mizuho Bank. As an additional step for realigning the group structure, Mizuho Financial Group was established on January 8, 2003 as a corporation organized under the laws of Japan, and on March 12, 2003, it became the holding company for the Mizuho group through a stock-for-stock exchange with Mizuho Holdings, which became an intermediate holding company focused on management of the Mizuho group’s banking and securities businesses. The legal and commercial name of the company is Mizuho Financial Group, Inc.

In May 2003, we initiated a project to promote early corporate revitalization of customers in need of revitalization or restructuring and to separate the oversight of restructuring borrowers from the normal credit origination function. In July 2003, our three principal banking subsidiaries, the former Mizuho Corporate Bank, the former Mizuho Bank and Mizuho Trust & Banking each transferred loans, equity securities and other claims outstanding relating to approximately 950 companies to new subsidiaries that they formed. In October 2005, based on the significant reduction in the balance of impaired loans held by these new subsidiaries, which we call the “revitalization subsidiaries,” we deemed the corporate revitalization project to be complete, and each of the revitalization subsidiaries was merged into its respective banking subsidiary parent.

In the fiscal year ended March 31, 2006, we realigned our entire business operations into a Global Corporate Group, Global Retail Group and Global Asset and Wealth Management Group. In October 2005, in connection with this realignment, we established Mizuho Private Wealth Management Co., Ltd., a private banking subsidiary, and converted Mizuho Holdings on October 1, 2005 from an intermediate holding company into Mizuho Financial Strategy Co., Ltd., an advisory company that provides advisory services to financial institutions.

In May 2009, Mizuho Securities and Shinko Securities Co., Ltd. conducted their merger, with the aim of improving our service-providing capabilities to our clients and to offer competitive cutting-edge financial services on a global basis.

In September 2011, Mizuho Trust & Banking became a wholly-owned subsidiary of Mizuho Financial Group, Mizuho Securities became an unlisted subsidiary of the former Mizuho Corporate Bank and Mizuho Investors Securities became a wholly-owned subsidiary of the former Mizuho Bank, through their respective stock-for- stock exchanges. The purpose of these stock-for-stock exchanges is to further enhance the “group collective capabilities” by integrating group-wide business operations and optimizing management resources such as workforce and branch network.

In January 2013, Mizuho Securities and Mizuho Investors Securities merged in order to provide integrated securities services as the full-line securities company of the Mizuho group. Mizuho Securities aims to further strengthen collaboration among banking, trust banking and securities businesses of the group, expand the company’s customer base to enhance the domestic retail business, and rationalize and streamline management infrastructure.

19

In April 2013, we turned Mizuho Securities, a consolidated subsidiary of Mizuho Financial Group, into a directly-held subsidiary of Mizuho Financial Group, whereby we moved to a new group capital structure, placing banking, trust banking, securities and other major group companies under the direct control of the holding company.

In July 2013, the former Mizuho Bank and the former Mizuho Corporate Bank merged, and the former Mizuho Corporate Bank, the surviving company, changed its trade name to Mizuho Bank, Ltd. The purpose of the merger is to become able to provide directly and promptly diverse and functional financial services to both the former Mizuho Bank and the former Mizuho Corporate Bank customers, utilizing the current “strengths” and “advantages” of the former Mizuho Bank and the former Mizuho Corporate Bank, and to continue to improve customer services by further enhancing group collaboration among the banking, trust and securities functions and, at the same time, to realize further enhancement of the consolidation of group-wide business operations and optimization of management resources, such as workforce and branch network, by strengthening group governance and improving group management efficiency.

4.B. Business Overview

General

We engage in banking, trust banking, securities and other businesses related to financial services.

Since the fiscal year 2013, we have been promoting “One MIZUHO New Frontier Plan—Stepping up to the Next Challenge—,” the three year medium-term business plan.

This medium-term business plan is a proactive plan aimed at launching the new Mizuho toward the “new frontier” of the next generation of finance, in response to structural and regulatory changes in the economy and society both in Japan and overseas. In the medium-term business plan, we have developed five basic policies reflecting our vision for our future, the necessary elements for the new frontier of finance and our future direction based on an analysis of our current situation, and to add more detail to these five basic policies, we have also developed ten basic strategies in terms of business strategy as well as business management and management foundations, etc., as follows.

Mizuho’s Vision

The most trusted financial services group with a global presence and a broad customer base, contributing to the prosperity of the world, Asia and Japan.

• The most trusted financial services group

• The best financial services provider

• The most cohesive financial services group

Five Basic Policies

• Further develop integrated strategies across the group for each customer segment to respond to the diverse needs of our customers.

• Contribute to sustainable development of the world and Japan by proactively responding to change.

• Mizuho Means Asia: accelerate globalizations.

20

• Build strong financial and management foundations to support the essence of Mizuho.

• Form strong corporate governance and culture in the spirit of One MIZUHO.

Ten Basic Strategies

Business Strategy

• Strengthen integrated financial services by unifying banking, trust banking and securities functions to respond to finely delineated corporate and personal banking segments.

• Perform consulting functions taking advantage of our industry and business knowledge and forward-looking perspective.

• Support formation of personal financial assets in Japan and invigorate their investment.

• Strengthen proactive risk-taking functions for growth industries and corporations.

• Strengthen and expand Asia-related business in Japan and on a global basis.

• Cultivate multi-level transactions by capturing the accelerating global capital and trade flows.

Business Management, Management Foundations, etc.

• Strengthen stable financial foundations based on abundant liquidity and appropriate capital levels.

• Establish the optimal management foundations (human resources and business infrastructure) to support business strategy.

• Further strengthen proactive governance and risk management.

• Embed the new Mizuho corporate identity toward forming a common culture throughout the group and take actions toward becoming the best financial services provider.

During the fiscal year 2014, the second fiscal year of the medium-term business plan, we have been striving to realize our commitment to become the most trusted financial services group.

Specifically, we have pursued unified strategies across the group-wide banking, trust banking and securities business areas with the intent of developing the cross-organizational financial know-how and industry knowledge of the group companies and thereby providing various financial services in a prompt manner through group-wide collaboration in response to various customer needs.

In addition, together with regional financial institutions, we have undertaken various regional revitalization activities, which include regional economic revitalization. We have also actively executed our policies to achieve even greater progress through, among other things, the execution of an agreement for the acquisition of a credit portfolio in respect of the wholesale market in North America from The Royal Bank of Scotland Group plc and the launch of preparations and discussions for integrating the asset management group companies in order to strengthen our asset management business.

With respect to corporate governance, we have endeavored to establish a corporate governance structure suitable for a global systemically important financial institution (“G-SIFI”), such as strengthening the functions of the holding company, as well as transforming Mizuho Financial Group into a Company with Three Committees (a Company with Committees under the Companies Act before the amendments thereto became effective as of May 1, 2015) in June 2014.

With respect to legal compliance, in conjunction with further enhancing its framework for the severance of business relations with anti-social elements, Mizuho Financial Group has intensified various efforts, including countermeasures against money laundering and terrorist financing.

21

We consider the fiscal year ending March 31, 2016, which is the last fiscal year of the medium-term business plan, to be the year to concentrate our efforts on strengthening our competitive advantage and will further advance the unified strategies across the group-wide banking, trust banking and securities business areas in order to realize the purpose of the plan. At the same time, we will strive to further strengthen our corporate governance.

As part of this approach, we determined to prioritize the following four business areas: “transactions with family-owned companies,” “transactions with large corporate customers,” “transactions with non-Japanese blue-chip companies” and “asset management business.” We established a system to focus on these areas by assigning the Officers in charge of Strategic Planning (Priority Assignments) to these areas. We will steadily promote this strategy and strive to secure its competitive advantage in these areas.

Enhancing of Corporate Governance

We will continue to endeavor to enhance the sophistication of the corporate governance structure that is suitable for a G-SIFI in consideration of requirements both in Japan and overseas for a strong corporate governance.

In addition, in June 2015, we filed our “Corporate Governance Report,” which describes our actions in response to the Corporate Governance Code, with the Tokyo Stock Exchange. After considering each principle of the code based on our intent and spirit, we have decided to comply with all of the principles.

Furthermore, we will commit ourselves to continue to conduct our business operations appropriately, in compliance with the structure for ensuring appropriate conduct of operations (internal control system) determined by a resolution of the Board of Directors.

Establishment of the Risk Appetite Framework

Starting this fiscal year, we have introduced a risk appetite framework, in light of enhancement of corporate values through the integrated group-wide operation of business strategies, financial strategies and risk controls. Specifically, we have established a policy on risk-taking, decided on the risk limits based on specific risk categories, and provided them to the units responsible for planning and advancing our business strategies. The risk-taking policy was set separately for each of the three categories: “universal risk-taking category,” “medium- to long-term objectives” and “current fiscal year objectives.” We will continue to promote effective business operations in accordance with our risk-taking policy, by nurturing a sound risk culture within the organization and by taking actions to raise the awareness of all officers and employees.

Establishment of Data Management Division and Assignment of Chief Data Officer

Against the backdrop of the tightening of financial regulations and the development of information technology world-wide, we established the Data Management Division in July 2014, and the officer in charge was the Chief Data Officer (“CDO”), in consideration of the importance of the collection and analysis, and the management of data that is applied to our business operations. The CDO is responsible for promoting data management and will centrally manage data for the banking, trust banking and securities businesses and will enhance marketing efforts through strong risk management and effective application of big data.

Establishment of Corporate Culture

We will continue to take initiatives to establish a strong corporate culture that will support corporate governance. Specifically, we will further strengthen continued actions related to each initiative by having each division and branch create its own visions and supporting the initiatives towards realizing these visions, commencing discussion sessions with senior management, and off-site meetings for general managers of head office divisions and marketing offices in Japan and overseas.

22

Further Market Penetration of Mizuho Brand

We have adopted the brand slogan, “One MIZUHO: Building the future with you,” to indicate our commitment to become “The most trusted financial services group with a global presence and a broad customer base, contributing to the prosperity of the world, Asia and Japan.” In order to further the market penetration of the Mizuho brand, we will strive to achieve the business plans for the fiscal year ending March 31, 2016 and make efforts to practice communication of the Mizuho brand. Specifically, we have started, since April 2015, the social contribution project, “Mizuho Heartful Action,” such as registering Mizuho branches as children’s refuge centers, increasing branches with interpreting services for non-Japanese speaking customers, providing tablet banking services that allow users to fill out forms online, and conducting voluntary activities within local communities. Moreover, we will continue to implement measures to further improve the value of the Mizuho brand.

Competition

We engage in banking, trust banking, securities and other businesses related to financial services and face strong competition in all of those areas of businesses partly due to deregulation of the Japanese financial industry.

30

Our major competitors in Japan include:

• Japan’s other major banking groups: Mitsubishi UFJ Financial Group and Sumitomo Mitsui Financial Group.

• Other banking institutions: These include city banks, trust banks, regional banks, shinkin banks (or credit associations), credit cooperatives, agricultural cooperatives, foreign banks and retail-oriented online banks.

• Securities companies and investment banks: These include both domestic securities companies and the Japanese affiliates of global investment banks.

• Government financial institutions: These include Japan Finance Corporation, Japan Post Bank, Development Bank of Japan and Japan Bank for International Cooperation.

In global markets, we face competition with other commercial banks and other financial institutions, particularly major global banks and the leading local banks in those financial markets outside Japan in which we conduct business.

Japanese Banking and Securities Industry

Private banking institutions in Japan are normally classified into two categories (the following numbers are based on information published by the Financial Services Agency, available as of May 7, 2015): (i) ordinary banks, of which there were 125, not including foreign commercial banks with banking operations in Japan; and (ii) trust banks, of which there were 16, including Japanese subsidiaries of foreign financial institutions and subsidiaries of Japanese financial institutions.

Ordinary banks consist mainly of city banks and regional banks. City banks, including Mizuho Bank, are based in large cities, operate domestically on a nation-wide scale through networks of branch offices and have strong links with large corporate customers in Japan. In light of deregulation and other competitive factors, however, many of these banks have placed increasing emphasis on other markets, including retail banking, small and medium-sized enterprise banking, international operations and investment banking. Regional banks are based in one of the prefectures of Japan and are generally much smaller in terms of total assets than city banks. In recent years, some regional banks have allied with each other and formed holding companies to operate in several prefectures. Customers of regional banks, other than local retail customers, include mostly regional enterprises and local public utilities, although regional banks also lend to large corporations. In addition to these types of banks, new retail-oriented banks have emerged in recent years, including Internet banks and banks specializing in placing their ATMs in convenience stores and supermarkets without maintaining a branch network.

Trust banks, including Mizuho Trust & Banking, are engaged in trust services in relation to, among others, money trust, pension trust and real estate trust services, in addition to banking business.

As of May 7, 2015, there were 54 foreign banks operating banking businesses in Japan. These banks are subject to a statutory framework similar to the regulations applicable to Japanese domestic banks. Their principal sources of funds come from their overseas head offices or other branches.

A number of government financial institutions, organized in order to supplement the activities of the private banking institutions, have been in the process of business and organizational restructuring in recent years. In

31

October 2008, some of the government financial institutions were consolidated to form Japan Finance Corporation, which mainly provides financing for small and medium-sized enterprises and those engaged in agriculture, forestry and fishery, and also provides export financing for Japanese corporations. In October 2008, Development Bank of Japan, which mainly engages in corporate financing, and Shoko Chukin Bank, which mainly engages in financing for small and medium-sized enterprises, were transformed into joint stock corporations. Japan Housing Finance Agency supports housing loans of private institutions through the securitization of such loans.

In April 2012, Japan Bank for International Cooperation, which provides policy-based finance with a mission to contribute to the sound development of Japan and the international economy and society, was spun off from Japan Finance Corporation and was established as a joint stock company wholly owned by the Japanese government.

Another distinctive element of the Japanese banking system is the role of the postal savings system. Postal savings deposits are gathered through the network of governmental post offices scattered throughout Japan, and their balance of deposits totaled over 200 trillion yen in the past. In recent years, the governmental postal business has been in the process of organizational restructuring. In 2003, the governmental postal business was transferred to Japan Post, a government-owned entity established in the same year, and in 2007, Japan Post was transformed into a government-owned joint stock corporation holding four operating companies including Japan Post Bank, which currently operates as an ordinary bank. Privatization of the banking and insurance subsidiaries, which was originally planned to be completed by 2017, was suspended in December 2009. In April 2012, a law was enacted under which Japan Post was retransformed into a joint stock corporation holding three operating companies in October 2012, and the deadline of the privatization of banking and insurance subsidiaries was abolished and replaced with a statement that the privatization is to be conducted in the near future. In December 2014, Japan Post Holdings published a plan for the listing of the three main companies of the Japan Post group, in accordance with which Japan Post Holdings will implement a secondary offering of the shares of the banking and insurance subsidiaries and list their shares in or after the middle of the fiscal year ending March 31, 2016, concurrently with the secondary offering of the shares of Japan Post Holdings held by the Japanese government and the listing of Japan Post Holdings. Japan Post Holdings, in the beginning, plans to gradually dispose of the two subsidiaries’ shares down to approximately 50% ownership, although Japan Post Holdings has not indicated a concrete schedule for the complete disposal of the two subsidiaries’ shares.

In the Japanese securities market, a large number of registered entities are engaged in securities businesses, such as sales and underwriting of securities, investment advisory and investment management services. As deregulation of the securities market progressed, several of the country’s banking groups have entered into this market through their subsidiaries. In addition, foreign financial institutions have been active in this market.

Supervision and Regulation

Japan

Pursuant to the Banking Act (Ginkou Hou) (Act No. 59 of 1981, as amended), the Prime Minister of Japan has authority to supervise banks in Japan and delegates certain supervisory control over banks in Japan to the Commissioner of the Financial Services Agency. The Bank of Japan also has supervisory authority over banks in Japan, based primarily on its contractual agreements and transactions with the banks.

Financial Services Agency

Although the Prime Minister has supervisory authority over banks in Japan, except for matters prescribed by government order, this authority is generally entrusted to the Commissioner of the Financial Services Agency. Additionally, the position of Minister for Financial Services was established by the Cabinet to direct the Commissioner of the Financial Services Agency and to support the Prime Minister.

32

Under the Banking Act, the Prime Minister’s authority over banks and bank holding companies in Japan extends to various areas, including granting and cancellation of licenses, ordering the suspension of business in whole or in part and requiring submission of business reports or materials. Under the prompt corrective action system, the Financial Services Agency, acting on behalf of the Prime Minister, may take corrective action in the case of capital deterioration of banks, their subsidiaries and companies having special relationships prescribed by the cabinet order. These actions include requiring a financial institution to formulate and implement reform measures, requiring it to reduce assets or take other specific actions and issuing an order to suspend all or part of its business operations.

Under the prompt warning system introduced in December 2002, the Financial Services Agency may take precautionary measures to maintain and promote the sound operations of financial institutions, even before those financial institutions become subject to the prompt corrective action system. These measures require a financial institution to reform profitability, credit risk management, stability and cash flow.

The Bank of Japan

The Bank of Japan is Japan’s central bank and serves as the principal instrument for the execution of Japan’s monetary policy. The principal measures by which the Bank of Japan implements monetary policy are the adjustment of its discount rate, its operations in the open market and the imposition of deposit reserve requirements. Banks in Japan are allowed to obtain borrowings from, and rediscount bills with, the Bank of Japan. Moreover, most banks in Japan maintain current accounts under agreements with the Bank of Japan pursuant to which the Bank of Japan is entitled to supervise, examine and audit the banks. The supervisory functions of the Bank of Japan are intended to enable it to ensure smooth settlement of funds among banks and other financial institutions, thereby contributing to the maintenance of an orderly financial system, whereas the supervisory practices of the Prime Minister or the Commissioner of the Financial Services Agency are intended to maintain the sound operations of banks and promote the security of depositors.

Examination of Banks

The Banking Act authorizes the Prime Minister to inspect banks and bank holding companies in Japan at any time. By evaluating banks’ systems of self-assessment, auditing their accounts and reviewing their compliance with laws and regulations, the Financial Services Agency monitors the financial soundness of banks, including the status and performance of their control systems for business activities. The inspection of banks is performed pursuant to a Financial Inspection Manual published by the Financial Services Agency. Currently, the Financial Services Agency takes the “better regulation” approach in its financial regulation and supervision. This consists of four pillars: optimal combination of rules-based and principles-based supervisory approaches; timely recognition of priority issues and effective response; encouraging voluntary efforts by financial institutions and placing greater emphasis on providing them with incentives; and improving the transparency and predictability of regulatory actions, in pursuit of improvement of the quality of financial regulation and supervision. In addition to individual financial institutions, the Financial Services Agency also supervises financial groups as financial conglomerates based on its Guidelines for Financial Conglomerates Supervision that focus on management, financial soundness and operational appropriateness of a financial conglomerate as a whole.

The Bank of Japan also conducts examinations of banks similar to those undertaken by the Financial Services Agency. The examinations are normally conducted once every few years, and involve such matters as examining asset quality, risk management and reliability of operations. Through these examinations, the Bank of Japan seeks to identify problems at an early stage and give corrective guidance where necessary.

In addition, the Securities and Exchange Surveillance Commission examines banks in connection with their financial instruments business activities in accordance with the Financial Instruments and Exchange Act of Japan (Kinyu Shouhin Torihiki Hou) (Act No. 25 of 1948, as amended).

33

Examination and Reporting Applicable to Shareholders

Under the Banking Act, a person who intends to hold 20% (in certain exceptional cases, 15%) or more of the voting rights of a bank is required to obtain prior approval of the Commissioner of the Financial Services Agency. In addition, the Financial Services Agency may request reports or submission of materials from, or inspect, any principal shareholder who holds 20% (in certain exceptional cases, 15%) or more of the voting rights of a bank, if necessary in order to secure the sound and appropriate operation of the business of such bank. Under limited circumstances, the Financial Services Agency may order such principal shareholder to take such measures as the Financial Services Agency deems necessary.

Furthermore, under the Banking Act, any person who becomes a holder of more than 5% of the voting rights of a bank holding company or bank must report its ownership of voting rights to the director of the relevant local finance bureau within five business days. In addition, a similar report must be made in respect of any subsequent change of 1% or more in any previously reported holding or any change in material matters set forth in reports previously filed, with some exceptions.

Deposit Insurance System

Under the Deposit Insurance Act (Yokin Hoken Hou) (Act No. 34 of 1971, as amended), depositors are protected through the Deposit Insurance Corporation in cases where financial institutions fail to meet their obligations. The Deposit Insurance Corporation is supervised by the Prime Minister and the Minister of Finance. Subject to limited exceptions, the Prime Minister’s authority is entrusted to the Commissioner of the Financial Services Agency.

The Deposit Insurance Corporation receives annual insurance premiums from insured banks. The effective premium rate from April 2010, which is the weighted average of the rates for deposits that bear no interest, are redeemable upon demand and are used by depositors primarily for payment and settlement purposes, and for other deposits, was 0.084%. However, for the fiscal years ended March 31, 2013, 2014 and 2015, because there were no insured bank failures, the effective premium rate of 0.07% was applied retroactively from the beginning of such fiscal years, and the amount paid in excess of such rates was respectively reimbursed to insured banks without interest. The effective premium rate from April 1, 2015 was changed to 0.042%.

The insurance money may be paid out in case of a suspension of deposits repayments, banking license revocation, dissolution or bankruptcy of the bank. Pay outs are generally limited to a maximum of ¥10 million of principal amount, together with any interest accrued with respect to each depositor. Only non-interest bearing deposits, redeemable on demand and used by depositors primarily for payment and settlement functions are protected in full.

Participation in the deposit insurance system is compulsory for city banks (including Mizuho Bank), regional banks, trust banks (including Mizuho Trust & Banking), credit associations and co-operatives, labor banks and other financial institutions.

Governmental Measures to Treat Troubled Institutions

Under the Deposit Insurance Act, a Financial Reorganization Administrator can be appointed by the Prime Minister if the bank is unable to fully perform its obligations with its assets or may suspend or has suspended repayment of deposits. The Financial Reorganization Administrator will take control of the assets of the bank, dispose of the assets and search for another institution willing to take over its business. Its business may also be transferred to a “bridge bank” established by the Deposit Insurance Corporation for the purpose of the temporary maintenance and continuation of operations of these types of institutions, and the bridge bank will seek to transfer the bank’s assets to another financial institution or dissolve the bank. The financial aid provided by the Deposit Insurance Corporation to assist another financial institution with succeeding the failed bank’s business may take the form of a monetary grant, loan or deposit of funds, purchase of assets, guarantee or assumption of debts, subscription of preferred stock or subordinated bonds, lending of subordinated loan, or loss sharing.

34

Where the Prime Minister recognizes that the failure of a bank which falls into any of (i) through (iii) below may cause an extremely grave problem in maintaining the financial order in Japan or the region where such bank is operating (“systemic risk”), without taking any of the measures described in (i) through (iii) below, the Prime Minister may confirm (nintei) to take any of the following measures, after the deliberation at the Financial Crisis Management Meeting: (i) if the bank does not fall into either of the banks described in (ii) or (iii), the Deposit Insurance Corporation may subscribe for shares or subordinated bonds of, or lend subordinated loans to the bank, or subscribe for shares of the bank holding company of the bank, in order to enhance capital adequacy of the bank; (ii) if the bank may suspend or has suspended repayment of deposits or is unable to fully perform its obligations with its assets, financial aid exceeding the pay-off cost may be available to such bank; and (iii) if the bank may suspend or has suspended repayment of deposits and is unable to fully perform its obligations with its assets, and the systemic risk cannot be avoided by the measure mentioned in (ii) above, the Deposit Insurance Corporation may acquire all of the bank’s shares. The expenses for implementation of the above measures will be borne by the bank industry, with an exception under which the Government of Japan may provide partial subsidies for such expenses.

New orderly and effective resolution regimes for financial institutions have been discussed internationally and “Key Attributes of Effective Resolution Regimes for Financial Institutions” was published by the Financial Stability Board in November 2011 and endorsed by the G20 leaders at the Cannes summit held in November 2011. Reflecting this global trend, pursuant to certain amendments to the Deposit Insurance Act that were promulgated in June 2013 and became effective on March 6, 2014, a new resolution regime was introduced in Japan.

Under the new resolution regime stipulated in the amendments to the Deposit Insurance Act and implementing ordinances thereunder, which became effective on March 6, 2014, financial institutions, including banks, insurance companies and securities companies and their holding companies, are subject to the regime.

Further, under the new resolution regime, among other things, where the Prime Minister recognizes that the failure of a financial institution which falls into either of (a) or (b) below may cause significant disruption in the financial markets or other financial systems in Japan without taking any of the measures described in (a) (specified item 1 measures)(tokutei dai ichigo sochi) or the measures described in (b) (specified item 2 measures)(tokutei dai nigo sochi), the Prime Minister may confirm (specified confirmation)(tokutei nintei) to take any of the following measures, after the deliberation at the Financial Crisis Management Meeting; (a) if the financial institution does not fall into a financial institution which is unable to fully perform its obligations with its assets, the Deposit Insurance Corporation shall supervise the operation of the business of and the management and disposal of assets of that financial institution (tokubetsu kanshi), and may provide it with loans or guarantees necessary to avoid the risk of significant disruption in the financial systems in Japan (shikin no kashitsuke tou), or subscribe for shares or subordinated bonds of, or lend subordinated loans to the financial institutions (tokutei kabushiki tou no hikiuke tou), in each case to be taken as necessary taking into consideration of the financial conditions of the financial institution; and (b) if the financial institution is or is likely to be unable to fully perform its obligations with its assets or has suspended or is likely to suspend repayment of its obligations, the Deposit Insurance Corporation shall supervise that financial institution (tokubetsu kanshi), and may provide financial aid necessary to assist merger, business transfer, corporate split or other reorganization in respect to such failed financial institution (tokutei shikin enjo). The expenses for implementation of the measures under this regime will be borne by the financial industry, with an exception under which the Government of Japan may provide partial subsidies for such expenses. If a measure set out in (b) above is determined to be taken with respect to a financial institution, the Prime Minister may order that the financial institution’s operation and assets be under the control of the Deposit Insurance Corporation. The business or liabilities of the financial institution subject to the supervision (tokubetsu kanshi) by the Deposit Insurance Corporation as set forth above may also be transferred to a “bridge bank” established by the Deposit Insurance Corporation for the purpose of the temporary maintenance and continuation of operations of, or repayment of the liabilities of, such financial institutions, and the bridge bank will seek to transfer the bank’s business or liabilities to another financial institution or dissolve the bank. The financial aid provided by the Deposit Insurance Corporation to assist merger, business transfer,

35

corporate split or other reorganization in respect to the financial institution set out in (b) may take the form of a monetary grant, loan or deposit of funds, purchase of assets, guarantee or assumption of debts, subscription of preferred stock or subordinated bonds, lending of subordinated loan, or loss sharing.

Recovery and Resolution Plan

In November 2014, the Financial Stability Board published the latest list of G-SIFIs. The list is annually updated by the Financial Stability Board each November, and the list as of November 2014 includes us. A recovery and resolution plan must be put in place for each G-SIFI, and be regularly reviewed and updated. In Japan, under the Comprehensive Guidelines for Supervision of Financial Instruments Business Operators, etc., as part of crisis management, financial institutions identified as G-SIFIs must prepare and submit a recovery plan, which includes the triggers to implement the recovery plan and an analysis of recovery options, to the Financial Services Agency, and the Financial Services Agency must prepare a resolution plan for each G-SIFI.

Capital Injection by the Government

The Strengthening Financial Functions Act (Kinyu Kinou no Kyouka no tame no Tokubetsu Sochi ni kansuru Houritsu) (Act No. 128 of 2004) was enacted on June 18, 2004 in order to establish a scheme of public money injection into financial institutions and thereby enhance the soundness of such financial institutions on or prior to March 31, 2008 and revitalize economic activities in the regions where they do business. On December 17, 2008, certain amendments to the Strengthening Financial Functions Act took effect. These amendments relaxed certain requirements for public money injection into Japanese banks and bank holding companies and other financial institutions under the prior scheme and extended the period of application therefor, which had expired on March 31, 2008, to March 31, 2012. These amendments aim to promote not only the soundness of such financial institutions but also the extension of loans or other forms of credit to small and medium-sized enterprises in order to revitalize local economies. In response to the Great East Japan Earthquake, the law was amended in June 2011 to extend the period for application to March 31, 2017 and to include special exceptions for disaster-affected financial institutions. None of the financial institutions within the Mizuho group are subject to such special exceptions.

Bank Holding Companies

Under the Banking Act, a bank holding company is prohibited from carrying out businesses other than administrating the businesses of its subsidiaries and matters incidental to such businesses. Business activities for subsidiaries of bank holding companies are limited to finance-related businesses and incidental businesses.

The Anti-Monopoly Act (Shiteki Dokusen no Kinshi oyobi Kousei Torihiki no Kakuho ni kansuru Houritsu) (Act No. 54 of 1947, as amended) prohibits a bank from holding more than 5% of another company’s voting rights. This does not apply to a bank holding company, although the bank holding company is subject to general shareholding restrictions under the Anti-Monopoly Act. The Banking Act does, however, prohibit a bank holding company and its subsidiaries, on an aggregate basis, from holding more than 15% (in contrast to 5% in the case of a bank and its subsidiaries) of the voting rights of certain types of companies not permitted to become subsidiaries of bank holding companies.

Financial Instruments and Exchange Act

The Financial Instruments and Exchange Act (Kinyu Shouhin Torihiki Hou) requires Mizuho Financial Group to file with the Director General of the Kanto Local Finance Bureau an annual securities report including consolidated and non-consolidated financial statements in respect of each financial period, supplemented by quarterly and extraordinary reports.

Under the Financial Instruments and Exchange Act, registered Financial Instruments Business Operators (kinyu-shouhin torihiki gyousha), such as Mizuho Securities, as well as Registered Financial Institutions (touroku kinyu kikan), such as Mizuho Bank and Mizuho Trust & Banking, are required to provide customers with detailed

36

disclosure regarding the financial products they offer and take other measures to protect investors, including a delivery of explanatory documents to such customers prior to and upon the conclusion of transactional agreements.

Financial Instrument Business Operators and Registered Financial Institutions are subject to the supervision of the Financial Services Agency pursuant to delegation by the Prime Minister of Japan. Some of the supervisory authority of the Financial Services Agency is further delegated to the Securities and Exchange Surveillance Commission, which exercises its supervisory power over such registered institutions by conducting site inspections and requesting information necessary for such inspections. Non-compliance or interference with such inspection may result in such registrants being subject to criminal penalty under the Financial Instruments and Exchange Act.

Certain amendments to the Financial Instruments and Exchange Act and the Banking Act, which came into effect on June 1, 2009, revamped the firewall regulations regarding the holding of concurrent offices or posts among banks, securities firms and insurance firms and required banks, securities firms and insurance firms to establish systems for managing conflicts of interest in order to protect customers’ interests and expanded the types of business services that banks and certain other financial firms can provide.

Sales of Financial Products

As a result of financial deregulation, more financial products, including highly structured and complicated products, can now be more freely marketed to customers. In response to this, the Act of Sales of Financial Products (Kinyu Shouhin no Hanbai tou ni kansuru Houritsu) (Act No. 101 of 2000, as amended), effective from April 2001, introduced measures to protect financial service customers by: requiring financial service providers to provide customers with certain important information, including risks with respect to deficit of principal associated with the financial products they offer and any restrictions on the period for exercising rights or the period for rescission, unless the customers fall within the ambit of professional investors or express their intent to the contrary; and holding financial service providers liable for damages caused by a failure to follow those requirements. The amount of loss of principal is refutably presumed to be the amount of damages. Additionally, the law requires financial service providers to follow certain regulations on solicitation measures as well as to endeavor to solicit customers in an appropriate manner and formulate and publicize a solicitation policy.

Self-Assessment and Reserves

The prompt corrective action system requires financial institutions to establish a self-assessment program that complies with the Inspection Manual issued by the Financial Services Agency and related laws such as the Financial Reconstruction Act (Kinyu Kinou no Saisei no tameno Kinkyu Sochi ni kansuru Houritsu) (Act No. 132 of 1998, as amended). Financial institutions are required to analyze their assets, giving due consideration to accounting principles and other applicable rules and to classify their assets into four categories according to asset recovery risk and risk of impairment based on the classification of the obligor (normal obligors, watch obligors, intensive control obligors, substantially bankrupt obligors and bankrupt obligors) taking into account the likelihood of repayment and the risk of impairment to the value of the assets. The results of self-assessment should be reflected in the write-off and allowance according to the standard established by financial institutions pursuant to the guidelines issued by the Japanese Institute of Certified Public Accountants and Inspection Manual issued by the Financial Services Agency. Based on the results of the self-assessment, financial institutions may establish reserve amounts for their loan portfolio as may be considered adequate at the relevant balance sheet date, even if all or part of such reserves may not be immediately tax deductible under Japanese tax law.

Based on the accounting standards for banks issued by the Japanese Bankers Association, a bank is required to establish general reserves, specific reserves and reserves for probable losses on loans relating to restructuring countries.

37

Credit Limits

The Banking Act restricts the aggregate amount of exposure to any single customer or customer group for the purposes of avoiding excessive concentration of credit risks and promoting the fair and extensive utilization of bank credit. The limits applicable to a bank holding company and bank with respect to their aggregate exposure to any single customer or customer group are established by the Banking Act and regulations thereunder. The Banking Act and the related regulations were amended, which became effective from December 2014, to tighten the previous restrictions to meet international standards. As a result of these amendments, the current credit limit for a single customer or a customer group is 25% of the total qualifying capital, with certain adjustments, of the bank holding company or bank and its subsidiaries and affiliates,.

Restriction on Shareholdings

The Act Concerning Restriction on Shareholdings by Banks (Ginkou tou no Kabushiki tou no Hoyu no Seigen tou ni kansuru Houritsu) (Act No. 131 of 2001, as amended) requires Japanese banks (including bank holding companies) and their subsidiaries to limit the aggregate market value (excluding unrealized gains, if any) of their holdings in equity securities to an amount equal to 100% of their Tier 1 capital in order to reduce exposure to stock price fluctuations.

Share Purchase Program

The Banks’ Shareholdings Purchase Corporation was established in January 2002 in order to purchase shares from banks and other financial institutions until September 30, 2006 pursuant to the Law Concerning Restriction on Shareholdings by Banks. The Bank’s Shareholdings Purchase Corporation is allowed to resume purchases of shares held by financial institutions as well as shares of financial institutions held by non-financial institutions, up to a maximum amount of ¥20 trillion between March 12, 2009 and March 31, 2017. The Bank’s Shareholdings Purchase Corporation purchased ¥1,026.5 billion of shares during the period from March 12, 2009 through May 31, 2015. The Bank’s Shareholdings Purchase Corporation will dispose of the purchased shares by March 31, 2027 by taking into consideration the effects on the stock market.

The Bank of Japan also purchased ¥387.8 billion of shares held by banks and other financial institutions during the period from February 23, 2009 through April 30, 2010. The Bank of Japan generally will not sell the purchased shares until March 31, 2016. The Bank of Japan will dispose of the purchased shares by September 30, 2021 by taking into consideration the effects on the stock market.

Capital Adequacy

The capital adequacy guidelines applicable to Japanese banks and bank holding companies with international operations supervised by the Financial Services Agency closely follow the risk-adjusted approach proposed by the Bank for International Settlements and are intended to further strengthen the soundness and stability of Japanese banks. Under the risk-based capital framework of these guidelines, balance sheet assets and off-balance-sheet exposures are assessed according to broad categories of relative risk, based primarily on the credit risk of the counterparty, country transfer risk and the risk regarding the category of transactions.

In December 2010, the Basel Committee on Banking Supervision issued its Basel III rules text, which builds on the International Convergence of Capital Measurement and Capital Standards document (“Basel II”), to strengthen the regulation, supervision, and risk management of the banking sector. Basel III text presents the details of global regulatory standards on bank capital adequacy and liquidity. The rules text sets out higher and better-quality capital, better risk coverage, the introduction of a leverage ratio as a backstop to the risk-based requirement, measures to promote the build-up of capital that can be drawn down in periods of stress, and the introduction of two global liquidity standards. For further information of the leverage ratio and the two global liquidity standards, see “Leverage Ratio” and “Liquidity” below, respectively.

38

The Financial Services Agency’s revisions to its capital adequacy guidelines became effective from March 31, 2013, which generally reflect rules in the Basel III text that have been applied from January 1, 2013.

Under the revised guidelines, the minimum capital adequacy ratio is 8% on both a consolidated and non-consolidated basis for banks with international operations, such as Mizuho Bank, or on a consolidated basis for bank holding companies with international operations, such as Mizuho Financial Group. Within the minimum capital adequacy ratio, the Common Equity Tier 1 capital requirement is 4.5% and the Tier 1 capital requirement is 6.0%.

Japanese banks with only domestic operations and bank holding companies the subsidiaries of which operate only within Japan are subject to the revised capital adequacy guidelines that have been applied from March 31, 2014, and those banks and bank holding companies are required to have a minimum Core Capital ratio of 4%. However, those banks and bank holding companies that apply the internal rating based approach are required to have a minimum Common Equity Tier 1 ratio of 4.5% on both a consolidated and non-consolidated basis, calculated on the assumption that the banks and bank holding companies are those with international operations.

Under the revised capital adequacy guidelines based on the Basel III rules that have been applied to banks and bank holding companies each with international operations from March 31, 2013, there are regulatory adjustments such as goodwill and other intangibles, deferred tax assets, investments in the capital of banking, financial and insurance entities etc. shall be deducted under certain conditions for the purpose of calculating capital adequacy ratios, and the requirements of regulatory adjustments were enhanced under the revised capital adequacy guidelines. For example, under the capital adequacy guidelines prior to the revision thereto under the Basel III rules, the maximum amount of net deferred tax assets under Japanese GAAP that major Japanese banks, including bank holding companies, could record without diminishing the amount of Tier 1 capital for purposes of calculating capital adequacy ratio was 20% of Tier 1 capital. Under the revised capital adequacy guidelines based on the Basel III rules, deferred tax assets that arise from temporary differences will be recognized as part of Common Equity Tier 1 capital, with recognition capped at 10% of Common Equity Tier 1 capital under certain conditions, while other deferred tax assets, such as those relating to net loss carryforwards, will be deducted in full from Common Equity Tier 1 capital net of deferred tax liabilities. These regulatory adjustments based on the Basel III rules began at 20% of the required deductions in the calculation of Common Equity Tier 1 capital in March 2014 and will be increased by 20% increments per year through March 2018 when the regulatory adjustments reach 100%.

The revised capital adequacy guidelines related to other requirements under the Basel III rules, such as the capital conservation buffer, have not yet been published.

Under the capital adequacy guidelines, banks and bank holding companies each with international operations are required to measure and apply capital charges with respect to their credit risks, market risks and operational risks.

Under the guidelines, banks and bank holding companies have several choices for the methodologies to calculate their capital requirements for credit risk, market risk and operational risk. Approval of the Financial Services Agency is necessary to adopt advanced methodologies for calculation, and Mizuho Financial Group started to apply the AIRB approach for the calculation of credit risk from the fiscal year ended March 31, 2009 and also apply the AMA for the calculation of operational risk from September 30, 2009.

The Basel Committee on Banking Supervision issued a consultative document on the risk management, capital treatment and supervision of interest rate risk in the banking book in June 2015. The document presents two options for the capital treatment of interest rate risk in the banking book; (i) a standardised Pillar 1 (minimum capital requirements) approach and (ii) an enhanced Pillar 2 approach. A standardised Pillar 1 approach is the adoption of a uniformly applied Pillar 1 measure for calculating minimum capital requirements

39

for interest rate risk, which would have the benefit of promoting greater consistency, transparency and comparability. An enhanced Pillar 2 approach, which includes quantitative disclosure of interest rate risk in the banking book based upon the proposed Pillar 1 approach, would better accommodate differing market conditions and risk management practices across jurisdictions. The schedule of the implementation is not stated explicitly.

For further information of the capital adequacy, see “Item 5. Operating and Financial Review and Prospects—Capital Adequacy—Regulatory Capital Requirements.”

Leverage Ratio

The leverage ratio framework is critical and complementary to the risk-based capital framework that will help ensure broad and adequate capture of both on- and off-balance sheet sources of banks’ leverage. This simple, non-risk-based measure will restrict the build-up of excessive leverage in the banking sector to avoid destabilizing deleveraging processes that can damage the broader financial system and the economy. Any final adjustments to the definition and calibration of the leverage ratio will be made by the Basel Committee on Banking Supervision by 2017, with a view to migrate to a Pillar 1 (minimum capital requirements) treatment on January 1, 2018, based on appropriate review and calibration.

For further information regarding the leverage ratio, see “Item 5. Operating and Financial Review and Prospects—Capital Adequacy—Regulatory Capital Requirements.”

Liquidity

Two minimum standards for funding liquidity will be introduced. The liquidity coverage ratio (“LCR”) is intended to promote resilience to potential liquidity disruptions over a thirty-day horizon and help ensure that global banks have sufficient, unencumbered, high-quality liquid assets (“HQLA”) to offset the net cash outflows it could encounter under an acute short-term stress scenario. The Group of Governors and Heads of Supervision agreed on a revised LCR standard on January 6, 2013, and the Basel Committee on Banking Supervision issued the text of the revised LCR standard on January 7, 2013. The LCR guidelines of the Financial Services Agency, which reflect the rules in such text, have been applied to banks and bank holding companies with international operations from March 31, 2015, under the LCR guidelines, LCR is defined as the ratio obtained by dividing the sum of the amounts of High-Quality liquid assets by the amount of net cash outflows, each as defined in and calculated pursuant to such guidelines. In accordance with the LCR standard under the LCR guidelines, the stock of unencumbered HQLA is to constitute “level 1” assets, which include cash, central bank reserves and certain marketable securities backed by sovereigns and central banks, and “Level 2” assets, which include certain government securities covered bonds, corporate debt securities and, to a limited extent, lower-rated corporate bonds, residential mortgage-backed securities and equities that meet certain conditions. “Level 2” assets are subject to certain haircuts based on types of securities and credit ratings. The minimum LCR under the LCR guidelines is 100% on both a consolidated and non-consolidated basis for banks with international operations or on a consolidated basis for bank holding companies with international operations, while it is subject to phase-in arrangements pursuant to which the LCR is introduced with a minimum requirement of 60% during the period from March 31 to December 31, 2015, which subsequently rises in equal annual steps of 10 percentage points to reach 100% on January 1, 2019. The Basel Committee on Banking Supervision issued final requirements for LCR-related disclosures on January 12, 2014, and the LCR disclosure guidelines of the Financial Services Agency, which reflect such requirements, have been applied to banks and bank holding companies with international operations from June 30, 2015. The LCR disclosure guidelines require such banks and bank holding companies to disclose their LCR in common templates starting from information as of June 30, 2015.

The net stable funding ratio (“NSFR”) requires a minimum amount of stable sources of funding at a bank relative to the liquidity profiles of the assets, as well as the potential for contingent liquidity needs arising from off-balance sheet commitments, over a one-year horizon. The Basel Committee on Banking Supervision finalized the NSFR framework in October 2014, and the NSFR will scheduled to be introduced as a minimum standard by the Financial Securities Agency by January 1, 2018.

Total Loss Absorbing Capacity

Related to capital adequacy, in November 2014, the Financial Stability Board issued for public consultation policy proposals consisting of a set of principles and a detailed term sheet on the adequacy of loss-absorbing and recapitalization capacity of G-SIBs. Under the proposal, G-SIBs are required to meet a new requirement for total loss absorbing capacity (“TLAC”), which should consist only of liabilities that can be effectively written down or converted into equity during resolution of a G-SIB without disrupting the provision of critical functions. The Financial Stability Board proposes that a minimum Pillar 1 common TLAC requirement be set within the range of 16-20% of risk-weighted assets and at least twice the Basel 3 leverage ratio requirement, and authorities may set additional Pillar 2 TLAC requirements for individual firms above the minimum Pillar 1 common TLAC requirement. The proposals will be finalized to form a new minimum standard for TLAC taking account of the results of the consultation and of the impact assessments. The final version is scheduled to be delivered to the G20 Leaders’ Summit scheduled to be held in November 2015.

Protection of Personal Information

The Personal Information Protection Act (Kojin Jouhou no Hogo ni kansuru Houritsu) (Act No. 57 of 2003, as amended) and related guidelines impose various requirements on businesses, including us, that use databases containing personal information, such as appropriate custody of such information and restrictions on information sharing with third parties. Non-compliance with the order issued by the Financial Services Agency to take necessary measures to comply with the law will subject us to criminal and/or administrative sanctions.

Prevention of Money Laundering

Under the Act Preventing Transfer of Profits Generated from Crime (Hanzai ni yoru Syueki no Iten Boushi ni kansuru Houritsu) (Act No. 22 of 2007, as amended), which addresses money laundering and terrorism concerns, financial institutions and other entities such as credit card companies are required to perform customer identification, submit suspicious transaction reports and maintain records of transactions. Certain amendments to the law became effective in April 2013, which tightened, among other things, customer identification requirements. Further amendments to the law were promulgated in November 2014 and will become effective by November 2016 for clarification of the judgment method of suspicious transactions, strict verification at the time of the conclusion of correspondence contracts and expansion of the obligation for business operators to make efforts to develop necessary systems.

Act Concerning Protection of Depositors from Illegal Withdrawals Made by Forged or Stolen Cards

The Act Concerning Protection of Depositors from Illegal Withdrawals Made by Forged or Stolen Cards (Gizou Kaado tou oyobi Tounan Kaado tou wo Mochiite Okonawareru Fuseina Kikaishiki Yochokin Haraimodoshi tou karano Yochokinsha no Hogo tou ni kansuru Houritsu) (Act No. 94 of 2005, as amended) requires financial institutions to establish internal systems to prevent illegal withdrawals of deposits using forged or stolen bank cards. The law also requires financial institutions, among other matters, to compensate depositors for any amount illegally withdrawn using forged bankcards, unless the financial institution can verify that it acted in good faith without negligence and that there was gross negligence on the part of the relevant account holder.

United States

As a result of our operations in the United States, we are subject to extensive U.S. federal and state supervision and regulation. We engage in U.S. banking activities through Mizuho Bank’s New York, Chicago and Los Angeles branches and Houston and Atlanta representative offices. We also own one bank in the United States, Mizuho Bank (USA), as well as controlling interests in several other subsidiaries, including Mizuho Trust & Banking Co. (USA), which is engaged primarily in the trust and custody business, and Mizuho Securities USA Inc., a U.S. broker dealer engaged in the securities business.

The USA PATRIOT Act of 2001 (the “PATRIOT Act”) contains measures to prevent, detect and prosecute terrorism and international money laundering by imposing significant compliance and due diligence obligations, creating new crimes and penalties and expanding the extraterritorial jurisdiction of the United States. In recent years, federal and state regulatory and law enforcement authorities have closely scrutinized the compliance by financial institutions with the Bank Secrecy Act and anti-money laundering rules.

Mizuho Financial Group and Mizuho Bank are financial holding companies (“FHCs”), and Mizuho Trust & Banking is a bank holding company, within the meaning of the U.S. Bank Holding Company Act of 1956, as amended (the “BHCA”), and are subject to regulation and supervision thereunder by the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”). As a matter of law, these three companies are required to act as a source of financial strength to Mizuho Bank (USA) and Mizuho Trust & Banking Co. (USA). The BHCA generally prohibits us from acquiring, directly or indirectly, the ownership or control of more than 5% of any class of voting shares of any company engaged in the United States in activities other than banking or activities that are financial in nature or incidental or complementary to financial activity. This general prohibition is subject to certain exceptions, including an exception that permits us to acquire up to 100% of the voting interests in any company engaged in nonfinancial activities that we do not routinely manage, generally for a period of up to 10 years, under our merchant banking authority. In addition, U.S. regulatory approval is generally required for us to acquire more than 5% of any class of voting shares of a U.S. bank, savings association or bank holding company.

Mizuho Financial Group and the former Mizuho Corporate Bank, now Mizuho Bank, became FHCs in December 2006. FHC status under the BHCA permits banking groups in the United States to engage in comprehensive investment banking businesses, such as the underwriting of and dealing in corporate bonds, equities and other types of securities. FHC status enables our group to promote our investment banking business on a broader basis in the United States.

As a financial holding company, we are also subject to additional regulatory requirements. For example, we and each of our U.S. insured depository institution subsidiaries with operations in the United States must be “well capitalized,” meaning a Tier 1 risk-based capital ratio of at least 6%, a total risk-based capital ratio of at least 10% and a leverage ratio of at least 5%. We and each of our U.S. insured depository institution subsidiaries must also be “well managed,” including that they maintain examination ratings that are at least satisfactory. Further, Mizuho Financial Group and Mizuho Bank must also meet such capital standards as calculated under their home country standards (which must be comparable to the capital required for a U.S. bank) and must be well managed under standards comparable to those required for a U.S. bank. Failure to comply with such requirements would require us to prepare a remediation plan, and we would not be able to undertake new business activities or acquisitions based on our status as a financial holding company during any period of noncompliance without the prior approval of the Federal Reserve Board, and divestiture or termination of certain business activities, or termination of our U.S. branches and agencies, may be required as a consequence of failing to correct such conditions within 180 days.

U.S. branches, agencies and representative offices of foreign banks must be licensed, and are also supervised and regulated, by either a state banking authority or by the Office of the Comptroller of the Currency, the U.S. federal bank regulatory agency that charters and regulates national banks and federal branches and agencies of foreign banks. Each branch and representative office in the United States of Mizuho Bank is state-licensed. Under U.S. federal banking laws, state-licensed branches and agencies of foreign banks may engage only in activities that would be permissible for their federally-licensed counterparts, unless the Federal Reserve Board determines that the additional activity is consistent with sound practices. U.S. federal banking laws also subject state-licensed branches and agencies to the single-borrower lending limits that apply to federal branches and agencies, which generally are the same as the lending limits applicable to national banks, but are based on the capital of the entire foreign bank.

The New York branch of Mizuho Bank is subject to supervision, examination and regulation by the New York State Department of Financial Services as well as by the Federal Reserve Board. Except for a prohibition

42

on such branch accepting retail deposits, a state-licensed branch generally has the same powers as a state-chartered bank in such state. New York State has an asset pledge requirement for branches equal to the greater of 1% of average total liabilities for the previous month or $2 million, provided that an institution designated as a “well-rated foreign banking corporation” is permitted to maintain a reduced asset pledge with a cap of $100 million. The New York State Department of Financial Services may require higher amounts for supervisory reasons. Each U.S. branch and representative office of Mizuho Bank is subject to regulation and examination by the state banking authority of the state in which it is located.

Mizuho Bank (USA) is a state-chartered bank that is a member of the Federal Reserve System whose deposits are insured by the Federal Deposit Insurance Corporation (“FDIC”). As such, Mizuho Bank (USA) is subject to regulation, supervision and examination by the Federal Reserve Board and the New York State Department of Financial Services, as well as to relevant FDIC regulation.

Mizuho Trust & Banking Co. (USA) is a state-chartered bank and trust company that is not a member of the Federal Reserve System, but whose deposits are insured by the FDIC. As such, Mizuho Trust & Banking Co. (USA) is subject to regulation, supervision and examination by the FDIC and the New York State Department of Financial Services.

In the United States, U.S.-registered broker-dealers are regulated by the U.S. Securities and Exchange Commission (the “SEC”). As a U.S.-registered broker-dealer, Mizuho Securities USA is subject to regulations that cover all aspects of the securities business, including sales methods, trade practices among broker-dealers, use and safekeeping of customers’ funds and securities, capital structure, recordkeeping, the financing of customers’ purchases and the conduct of directors, officers and employees.

In the United States, comprehensive financial regulatory reform legislation, titled the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd Frank Act”), was signed into law by President Obama on July 21, 2010. Among other things, the Dodd-Frank Act directs the federal banking regulators to establish minimum leverage and risk-based capital requirements for insured depository institutions and depository institution holding companies.

The Dodd-Frank Act provides regulators with tools to impose greater capital, leverage and liquidity requirements and other prudential standards, particularly for financial institutions that pose significant systemic risk and bank holding companies with greater than $50 billion in consolidated assets. In imposing such heightened prudential standards on foreign banking organizations such as Mizuho Bank, the Federal Reserve Board is directed to take into account the principle of national treatment and equality of competitive opportunity, and the extent to which the foreign bank holding organization is subject to comparable home country standards. On February 18, 2014, the Federal Reserve Board finalized regulations that will impose enhanced prudential standards on certain large foreign banking organizations having a U.S. presence, such as Mizuho Bank. In particular, large foreign banking organizations, including us, and their U.S. operations are subject to risk management requirements, risk-based capital and leverage limits, capital stress testing requirements, liquidity requirements and, in certain circumstances, asset management requirements. Additionally, the Federal Reserve Board expects to finalize single counterparty credit limits and early remediation requirements for foreign banking organizations at a later date. In addition, foreign banking organizations with consolidated U.S. assets of $50 billion or more (excluding the assets of U.S. branches and agencies) will be required to create a separately capitalized top-tier U.S. intermediate holding company (“IHC”) that will hold all of its U.S. subsidiaries and be subject to certain capital, liquidity and other enhanced prudential standards on an IHC consolidated basis.

Under Section 619 of the Dodd-Frank Act, also known as the so-called “Volcker Rule,” any insured depository institution; any insured depository institution holding company; any non-U.S. bank with branches in the United States, such as Mizuho Bank; and any affiliate or subsidiary of such entities (each, a “banking entity”) will be prohibited from engaging in proprietary trading or from investing in or sponsoring private equity or hedge funds, subject to certain limited exceptions. U.S. financial regulators approved final rules implementing Section 619 of the Dodd-Frank Act on December 10, 2013. At the time of their release, these final rules included

43

an initial conformance period requiring banking entities to bring their activities and investments into compliance by July 21, 2015, absent further extension by the Federal Reserve Board. On December 18, 2014, the Federal Reserve Board announced an extension to the Volcker Rule conformance period, to give banking entities until July 21, 2016 to conform investments in and relationships with covered funds and foreign funds that were in place prior to December 31, 2013 (“legacy covered funds”). The Federal Reserve Board also announced its intention to act in the future to grant banking entities an additional one-year extension of the conformance period until July 21, 2017, to conform ownership interests in and relationships with these legacy covered funds. The Federal Reserve did not act to extend the conformance period for proprietary trading activities.

Disclosure Pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act

Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 (“Section 219”) added Section 13(r) to the U.S. Securities Exchange Act of 1934, requiring each SEC reporting issuer to disclose in its annual and, if applicable, quarterly reports whether it or any of its affiliates have knowingly engaged in specified activities, transactions or dealings relating to Iran or with the Government of Iran or certain designated persons or entities involved in terrorism or the proliferation of weapons of mass destruction during the period covered by such filing. Section 219 requires disclosure even of certain activities not prohibited by U.S. or other law and even if such activities were conducted outside the United States by non-U.S. affiliates in compliance with local law.

Our affiliate Mizuho Bank is our only affiliate to have engaged in activity that is relevant for this purpose. Mizuho Bank maintains compliance policies and procedures to conform its operations to all applicable economic sanctions laws and regulations, and is increasing resources dedicated to this effort. In that context, and only after confirming that such transactions did not involve prohibited or sanctionable activity under U.S. or other economic sanctions, non-U.S. branches of Mizuho Bank engaged in a limited number of activities reportable under Section 219 during the period covered by this annual report, as described below. No U.S. branches of Mizuho Bank were involved in any of these activities.

Legacy guarantees and loan obligations

During the period covered by this disclosure, Mizuho Bank was party to two legacy counter guarantees that were opened in connection with activities of its customers for the benefit of Iranian banks. When such guarantees were entered into, the banks in question had not been designated under U.S. Executive Orders (“E.O.”) 13224 or 13382, although they were subsequently so designated. Mizuho Bank maintained these guarantees post-designation only after confirming that such transactions did not involve prohibited or sanctionable activity under U.S. or other economic sanctions. As contractual obligations, these guarantees cannot be exited by Mizuho Bank unilaterally until there is full performance under the contract that is supported by the counter guarantees. In the fiscal year ended March 31, 2015, Mizuho Bank received fees of approximately ¥0.7 million attributable to these guarantees and net profits of less than that amount. Mizuho Bank did not pay guarantee fees to Iranian banks during this period. Mizuho Bank continues to seek to terminate these counter guarantees. Mizuho Bank has no intention to enter into any further similar guarantees.

Activities through correspondent banking accounts

In the fiscal year ended March 31, 2015, Mizuho Bank conducted a limited number of fund transfers through accounts it maintains for or at a limited number of Iranian banks designated under E.O. 13224 or 13382 and a limited number of other banks related to the Government of Iran. Mizuho Bank processed these transfers only after confirming that such transactions did not involve prohibited or sanctionable activity under U.S. or other economic sanctions and obtaining licenses issued by Japan’s Ministry of Finance where necessary. Estimated gross revenue to Mizuho Bank in the fiscal year ended March 31, 2015 attributable to this activity, excluding the humanitarian transactions described below, was approximately ¥0.2 million, with a net profit of less than that amount. Mizuho Bank will continue processing transfers through these accounts only under the limited circumstances where the transfer would conform to Mizuho Bank’s compliance policies and procedures, applicable international sanctions laws, and after obtaining a license issued by Japan’s Ministry of Finance where necessary.

44

Humanitarian transactions through correspondent banking accounts

In addition, in accordance with the Joint Plan of Action (JPOA) agreed between EU3+3 (France, Germany, the United Kingdom, China, Russia and the United States) and Iran in November 2013, Mizuho Bank has been providing settlement services in connection with humanitarian trade to assist in meeting Iran’s domestic needs, namely food, agricultural commodities, medicines and medical devices, since March 2014. The overall framework for these settlement services is based on an agreement between U.S. and Japanese authorities, and the relevant U.S. regulator authorizes that the settlement services are in compliance with applicable U.S. laws and regulations. The purchasers of the humanitarian goods were entities in or affiliated with Iran, including the Iranian government. The sellers of the humanitarian goods were entities permitted by U.S. and Japanese regulators. These transactions did not involve U.S. dollars nor clearing services of U.S. banks for the settlement of payments. These transactions were conducted through the use of special purpose yen accounts maintained with Mizuho Bank outside of the United States by Iranian financial institutions that are controlled by the Iranian government. Estimated gross revenue to Mizuho Bank in the fiscal year ended March 31, 2015 attributable to this activity was approximately ¥36.7 million, with a net profit of less than that amount.

Mizuho Bank intends to continue to provide these remittance and other settlement services in connection with the exports of humanitarian goods to Iran in close coordination with U.S. and Japanese authorities.

Other Jurisdictions

Our operations elsewhere in the world are subject to regulation and control by local supervisory authorities, including local central banks.

Overview

The Mizuho Group

We provide a broad range of financial services in domestic and overseas markets. The principal activities and subsidiaries are the following:

• Mizuho Bank provides a wide range of financial products and services mainly in relation to deposits, lending and exchange settlement to individuals, SMEs, large corporations, financial institutions, public sector entities and foreign corporations, including foreign subsidiaries of Japanese corporations;

• Mizuho Trust & Banking provides products and services related to trust, real estate, securitization and structured finance, pension and asset management and stock transfer agency; and

• Mizuho Securities provides full-line securities services to individuals, corporations, financial institutions and public sector entities.

We also provide products and services such as those related to trust and custody, asset management, private banking, research services, information technology-related services and advisory services for financial institutions through various subsidiaries and affiliates.

In July 2013, the former Mizuho Bank and the former Mizuho Corporate Bank merged, and the former Mizuho Corporate Bank, the surviving company, changed its trade name to Mizuho Bank. The purpose of the merger was to become able to provide directly and promptly diverse and functional financial services to customers of both banks, utilizing the current “strengths” and “advantages” and to continue to improve customer services by further enhancing group collaboration among the banking, trust and securities functions. At the same time, we aim to realize further enhancements of the consolidation of group-wide business operations and optimization of management resources, such as work force and branch network, by strengthening group governance and improving group management efficiency.

In June 2014, we transformed into a “Company with Three Committees,” as defined in the Companies Act, in order to further enhance corporate governance through strengthening the supervisory function of the Board of Directors over the execution of our business and improving the transparency of management processes, and in order to enhance the flexibility of management by facilitating swifter decision making.

Principal Sources of Income and Expenses

Net Interest Income

Net interest income arises principally from the lending and deposit-taking and securities investment activities of our banking subsidiaries and is a function of:

• the amount of interest-earning assets and interest-bearing liabilities;

• the average interest rate spread (the difference between the average yield of interest earned on interest-earning assets and the average rate of interest paid on interest-bearing liabilities); and

• the general level of interest rates.

Principal items constituting interest-earning assets include loans, investments, trading account assets, receivables under resale agreements and receivables under securities borrowing transactions. Principal items constituting interest-bearing liabilities include deposits, trading account liabilities, short-term borrowings (such as payables under repurchase agreements and payables under securities lending transactions) and long-term debt.

Provision (Credit) for Loan Losses

Provision (credit) for loan losses is charged against (or credited to) income to keep the allowance for loan losses at a level that is appropriate to absorb probable losses inherent in the credit portfolio. For a description of the approach and methodology used to establish the allowance for loan losses, see “—Financial Condition—Allowance for loan losses.”

Noninterest Income

Noninterest income consists mainly of fee and commission, investment gains (losses)—net, trading account gains (losses)—net and foreign exchange gains (losses)—net.

Fee and commission include the following:

• fee and commission from securities-related business, including brokerage fee and commission related to securities underwriting, fee and commission related to investment trusts and individual annuities and other securities-related activities;

• fee and commission from deposits and lending business, which consist mostly of fee and commission related to our loan businesses, including fees related to the arrangement of syndicated loans and other financing transactions such as arrangement fees related to management buy-out transactions and fees related to deposits such as account transfer charges;

• fee and commission from remittance business, including service charges for domestic and international funds transfers and collections;

• trust fees, including trust fees earned primarily through fiduciary asset management and administration services for corporate pension plans and investment funds; and

• fees for other customer services, including fees related to our agency businesses, such as administration fees related to Japan’s principal public lottery program, as well as guarantee fees and others.

Investment gains (losses)—net primarily include net gains and losses on sales of marketable securities, such as equity and bond investments. In addition, impairment losses are recognized when management concludes that declines in fair value of investments are other-than-temporary.

Trading account gains (losses)—net include gains and losses from transactions undertaken for trading purposes, including both market making for customers and proprietary trading, or transactions through which we seek to capture gains arising from short-term changes in market value. Trading account gains (losses)—net also include gains and losses related to changes in the fair value of derivatives and other financial instruments not eligible for hedge accounting under U.S. GAAP that are utilized to offset mainly interest rate risk related to our various assets and liabilities, as well as gains and losses related to changes in the fair value of foreign currency-denominated available-for-sale securities that are elected for fair value treatment under ASC 825. For further information on the fair value option, see note 27 to our consolidated financial statements included elsewhere in this annual report.

Foreign exchange gains (losses)—net mainly include translation gains and losses related to our foreign currency-denominated assets and liabilities and gains and losses related to foreign exchange trading activities, including market making for customers and proprietary trading.

Noninterest Expenses

Noninterest expenses primarily include salaries and employee benefits, general and administrative expenses, occupancy expenses and fee and commission expenses.

Salaries and employee benefits include expenses incurred for salaries, bonuses and compensation to directors and employees. They also include expenses related to pension and other employee retirement benefit plans.

The principal items included in general and administrative expenses are amortization of software, tax expenses such as consumption tax and property tax that are not income taxes and other expenses, including premiums for deposit insurance.

The principal items included in occupancy expenses are expenses related to premises and equipment, including depreciation, losses on disposal and lease expenses.

The principal items included in fee and commission expenses are fee and commission expenses for remittance services, which mainly include commission expenses paid in connection with remittance transactions and securities-related businesses, which mainly include transactions costs such as brokerage fees paid.

Operating Environment

We operate principally in Japan, and our performance has generally tracked the macro economy of Japan.

Since the fiscal year ended March 31, 2013, the gradual recovery in the global economy has continued, although some weaknesses in the recovery have been seen in some regions. In the fiscal year ended March 31, 2015, this recovery continued particularly in the major industrialized countries, but it remained necessary to monitor the economic outlook for Europe, China and emerging countries, geopolitical risks, and the effect of the decline in crude oil prices. In the United States, the economy continues to recover as employment conditions improved and consumer spending picked up. It is expected that the steady recovery in the economy will continue, while the possible effects of movements toward normalization of monetary policy requires continued monitoring. In Europe, the economies of the Euro area continued to recover gradually, in addition to steady recovery in the United Kingdom. Although it is expected that the economies of the region will continue to follow a track to recovery, the effect of the consequence of debt problems (including developments in Greece), high unemployment rates, the effect of the slowdown of the Russian economy and conflicts in Ukraine and trends in monetary policy require continued monitoring. In Asia, overall economic growth lacked momentum, partially due to the weakening in exports. In the coming year, it is expected that regional demand will increase supported by low crude oil prices. However, because there are still uncertainties in the global economy, such as the

50

potential interest rate hike in the United States which could draw capital out from the region, it is expected that growth of the regional economy will remain gradual. In China, although the economy continued to grow in a stable manner, the pace of economic growth was significantly slower. The Chinese government itself described the current situation of China’s economy as the “New Normal,” under which it is expected to continue to grow at a medium to high rate. However, a possibility of a slowdown in growth rate began to be recognized mainly due to the issues of excess equipment in the manufacturing sector and weakness in the real estate market. In addition, the Shanghai stock exchange composite index has recently been showing significant volatility and requires continued monitoring. In Japan, as the gradual economic recovery trend continued, there were improvements in employment conditions and companies’ earnings. As for the future outlook of the Japanese economy, while due attention is required for the risk of the slowing down of overseas economies, the Japanese economy can be expected to continue picking up, supported by such factors as growth in consumer spending backed by a recovery in employee wages and increased exports due to the continued trend of depreciation of the yen against other major currencies.

Key indicators of Japanese economic conditions in recent periods include the following:

• Japan’s real gross domestic product on a year-on-year basis increased by 1.0% and 2.1% in the fiscal years ended March 31, 2013 and 2014, respectively, and decreased by 0.9% in the fiscal year ended March 31, 2015. Japan’s real gross domestic product on a quarterly basis, compared to the corresponding period of the previous year, increased consecutively from the first quarter of calendar 2013 through the first quarter of calendar 2014 and decreased consecutively from the second quarter of calendar 2014 through the first quarter of calendar 2015.

• The Japanese government has been stating in its monthly economic reports that “the Japanese economy is on a moderate recovery,” while noting that “weakness can be seen in private consumption” in January and February 2015 and that “improvement can be seen in the corporate sector” in March and April 2015. The reports in May and June 2015 further noted that “private consumption is showing signs of picking up” and that “consumer prices are rising moderately.” The June 2015 report also noted that “business investment is picking up recently.”

• Japan’s core nationwide consumer price index decreased by 0.2% in the fiscal year ended March 31, 2013, but increased by 0.8%, 2.8% in the fiscal year ended March 31, 2014 and 2015.

The following chart shows the growth rates of Japan’s gross domestic product on a year-on-year basis and Japan’s core nationwide consumer price indices from the first quarter of 2012 through the first quarter of 2015:

• In January 2013, the Bank of Japan announced that it would set a “price stability target” at 2% in terms of the year-on-year rate of change in the consumer price index and introduced the “open-ended asset purchasing method” under the asset purchase program, pursuant to which financial assets will be purchased on a monthly basis without setting any termination date, for the purpose of taking additional steps to provide monetary accommodation decisively. Furthermore, the Japanese government and the Bank of Japan released a joint statement that they would strengthen their policy coordination and work together in order to overcome deflation early and achieve sustainable economic growth with price stability. In April 2013, the Bank of Japan announced that it would introduce the “quantitative and qualitative monetary easing” to enter a new phase of monetary easing and that it would continue with the easing which aims to achieve the price stability target of 2% until that target is maintained in a stable manner. Under the easing, the Bank of Japan changed the main operating target for money market operations from the uncollateralized overnight call rate to the monetary base, and announced that it would double the monetary base and the amounts outstanding of Japanese government bonds as well as Exchange-traded funds (“ETFs”) in two years and more than double the average remaining maturity of Japanese government bonds purchases. In October 2014, for the purpose of pre-empting manifestation of the risk that the conversion of deflationary mindsets might be delayed and maintaining the improving momentum of expectation formation, the Bank of Japan announced that it would expand the “quantitative and qualitative monetary easing.” In particular, the Bank of Japan also announced that it would expand the monetary base to be increased at an annual pace of about ¥80 trillion (an addition of about ¥10-20 trillion compared with the past). The Bank of Japan also announced that it would expand the purchases of Japanese government bonds to be increased at an annual pace of about ¥80 trillion (an addition of about ¥30 trillion compared with the past) and expand the purchases of ETFs and Japan real estate investment trusts so that their amounts outstanding would be increased at an annual pace of ¥3 trillion (tripled compared with the previously announced amount) and ¥90 billion (tripled compared with the previously announced amount), respectively. Additionally, the Bank of Japan announced it would make ETFs that track the JPX-Nikkei Index 400 eligible for purchase.

Capital Improvements

All yen figures and percentages in this subsection are truncated.

We have been implementing disciplined capital management by pursuing the optimal balance between strengthening of stable capital base and steady returns to shareholders as described below.

Strengthening of Stable Capital Base

In the fiscal year ended March 31, 2015, we strengthened our capital base mainly as a result of earning ¥611.9 billion of consolidated net income (under Japanese GAAP).

With respect to redemptions of previously issued securities, since April 2014, we have redeemed various securities that are eligible Tier 1/Tier 2 capital instruments subject to phase-out arrangements under Basel III upon their respective initial optional redemption dates or their respective maturity dates. With respect to Tier 1 capital, in June 2014, we redeemed $850.0 million and ¥139.5 billion of non-dilutive Tier 1 preferred securities issued by our overseas special purpose companies in February 2009 and June 2009, respectively. In June 2015, we redeemed ¥355.0 billion, ¥72.5 billion and ¥25.0 billion of non-dilutive Tier 1 preferred securities issued by our overseas special purpose companies in December 2008, August 2009 and September 2009, respectively. With respect to Tier 2 capital, in April 2014, we redeemed $1.5 billion of dated subordinated bonds issued by our overseas special purpose company. We redeemed ¥66.0 billion, ¥60.0 billion, ¥55.0 billion and ¥60.0 billion of dated subordinated bonds in June 2014, August 2014, September 2014 and February 2015, respectively, all of which were issued by our subsidiary bank.

With respect to new issuances, we issued ¥100.0 billion, ¥50.0 billion and ¥50.0 billion of dated subordinated bonds with a write-down feature that are Basel III-eligible Tier 2 capital instruments through public offerings to wholesale investors in Japan in July 2014, December 2014 and June 2015, respectively. In addition, on July 17, 2015, we announced our decision to issue, to qualified institutional investors in Japan, ¥300.0 billion of Additional Tier 1 perpetual subordinated bonds with optional-redemption clause and write-down clause.

Our Common Equity Tier 1 capital ratio under Basel III was 8.80% and 9.43% as of March 31, 2014 and 2015, respectively. We aim to strengthen our capital base, by March 31, 2016, to the level that enables us to stably secure our Common Equity Tier 1 capital ratio under Basel III of 8% or higher (on a fully-effective basis and including the outstanding balance of the eleventh series class XI preferred stock, which was ¥213.1 billion as of March 31, 2015, that will become mandatorily converted into common stock, and will thus be fully recognized as Common Equity Tier 1 capital, by July 2016). We believe that we will be able to secure a sufficient Common Equity Tier 1 capital ratio under Basel III as of March 31, 2019 when it becomes fully effective pursuant to its phase-in implementation. The foregoing target is based on capital regulations that have been announced to date.

The foregoing statements include forward-looking statements and are subject to risks, uncertainties and assumptions. See “Forward-looking Statements” and “Item 3.D. Key Information—Risk Factors.”

56

Steady Returns to Shareholders

We paid cash dividends with respect to the fiscal year ended March 31, 2015 of ¥7.5 per share of common stock (including interim dividend payments of ¥3.5 per share), an increase of ¥1.0 per share from the previous fiscal year.

We continuously consider the optimal balance between strengthening of stable capital base and steady returns to shareholders. We will comprehensively consider the business environment such as the Mizuho group’s business results, profit base, capital, and domestic and international regulation trends such as the Basel framework and determine cash dividend payments for each term.

Business Trends

Based on our current operating environment and management focus, we believe that the trends that are most significant to our current and future results of operations include the following:

Loans and Deposits

Loan volume

Our total loan balance increased on a year-on-year basis in the fiscal year ended March 31, 2015 due mainly to an increase in overseas loans. The increase in overseas loans was due mainly to an increase in loans to commercial and industrial and banks and other financial institutions, mainly in Americas and Asia.

Margins between loans and deposits

In April 2013, the Bank of Japan announced that it would introduce the “quantitative and qualitative monetary easing” to enter a new phase of monetary easing both in terms of quantity and quality, and the uncollateralized overnight call rate has been maintained at around 0 to 0.1% for several years. Reflecting a decline in short-term interest rate levels of the yen, the average yield on domestic loans decreased from 1.17% in the fiscal year ended March 31, 2014 to 1.09% in the fiscal year ended March 31, 2015, and the average rate on domestic interest-bearing deposits decreased from 0.07% to 0.06%.

Provision (credit) for loan losses

Credit for loan losses decreased by ¥66 billion from the previous fiscal year to ¥60 billion in the fiscal year ended March 31, 2015 due primarily to an increase in allowance for loan losses on impaired loans related to certain domestic borrowers, although we continued to record a credit for loan losses and recorded a decrease in allowance for loan losses on non-impaired loans as a result of upgrades in the obligor categories of a broad range of borrowers, reflecting the continuing gradual recovery of the Japanese economy. The amount of provision for loan losses in future fiscal years will depend largely on trends in the credit quality of borrowers, which in turn will be affected by the domestic and global economic environment and other factors, and changes in the value of collateral on our loans.

Fee and Commission

For the fiscal year ended March 31, 2014, fee and commission increased by ¥63 billion from the previous fiscal year to ¥676 billion due mainly to an increase in fee and commission from securities-related business, such as those related to investment trusts and individual annuities as a result of the upturn in domestic stock markets, and an increase in fees for other customer services. For the fiscal year ended March 31, 2015, fee and commission increased by ¥40 billion from the previous fiscal year to ¥716 billion due mainly to an increase in fee and commission from deposits and lending business as a result of our increased involvement in large overseas transactions, and an increase in fee and commission from other customer services, due mainly to an increase in fees related to real estate in our trust and asset management business of a principal banking subsidiary.

57

Debt and Equity Securities Portfolio

The amount of our funding through deposits significantly exceeds our total loans. As a result, we allocate a significant portion of such excess among investments in debt securities, including Japanese government bonds and investments in equity securities consisting mainly of common stock of Japanese listed company customers. We also hold some credit and alternative investments for the purpose of diversifying our risks and expanding our income sources.

Increases in long-term interest rates generally lead to a decline in the fair value of our portfolio of debt securities, a vast majority of which consists of Japanese government bonds. As of March 31, 2015, we had a total of ¥22,674 billion of available-for-sale debt securities within our investments, of which ¥17,414 billion was Japanese government bonds. Changes in fair value of such available-for-sale debt securities are reflected in accumulated other comprehensive income, net of tax in equity or, in the case of other-than-temporary impairments, charged to income as an impairment loss. We had ¥27,227 billion and ¥22,674 billion of available-for-sale debt securities as of March 31, 2014 and 2015, respectively, and net unrealized gains of ¥60 billion and ¥73 billion were reflected in accumulated other comprehensive income, net of tax as of such dates, respectively. We earned investment gains related to bonds of ¥60 billion in the fiscal year ended March 31, 2014 and ¥104 billion in the fiscal year ended March 31, 2015. The increase in investment gains related to bonds was due mainly to an increase in gains on sales of bonds, which reflected a decline in long-term interest rates. As the Bank of Japan announced a “price stability target” of 2% in January 2013 and the changes in interest rates that could result may have a substantial impact on the value of our Japanese government bond portfolio, in order to prepare for the risk of sudden and significant future interest rate rise, we continue to manage our Japanese government bond portfolio conservatively by managing the average remaining period of our portfolio and strengthening risk management including through the use of internal stress tests.

Because the size of our portfolio of marketable equity securities is substantial, we are subject to significant equity market risk, as increases in unrealized gains and losses related to changes in the fair value of available-for-sale marketable equity securities are reflected in accumulated other comprehensive income, net of tax in equity or, in the case of other-than-temporary impairments to fair value, charged to income as an impairment loss. As of March 31, 2013, 2014 and 2015, we recorded net unrealized gains related to marketable equity securities of ¥1,440 billion, ¥1,754 billion and ¥2,699 billion, respectively, in accumulated other comprehensive income, net of tax in equity. For the fiscal years ended March 31, 2013, 2014 and 2015, impairment losses on available-for-sale securities were ¥76 billion, ¥5 billion and ¥1 billion, respectively, of which impairment losses on marketable equity securities were ¥72 billion, ¥4 billion and ¥1 billion, respectively. We plan to continue managing the size of our stock portfolio in light of the equity market risk that it subjects us to.

Exposure to Certain European Countries (GIIPS)

In Europe, fiscal problems in certain countries, including Greece, Ireland, Italy, Portugal and Spain, have affected the financial system and the real economy, and the uncertainty concerning European economic activity continues to present a risk of a downturn in the world economy. As of March 31, 2015, our exposure to obligors in such countries was not significant. Specifically, our principal banking subsidiaries (including their overseas subsidiaries) had a total of approximately $6.4 billion in exposure to obligors in such countries. The breakdown by country and by type of obligor was as follows:

	As of March 31,				Increase (decrease)

Notes:

(1) Figures in the above table are on a managerial accounting basis. The difference between the exposure based on U.S. GAAP and that based on managerial accounting is attributable mainly to the netting of derivatives exposure as described in footnote 2 below and does not have a material impact on total exposure amounts set forth in the above table.

(2) Figures in the above table represent gross exposure except for derivatives exposure which takes into consideration legally enforceable master netting agreements.

Exposure to Russia and Ukraine

As for our exposure to obligors in Russia, our principal banking subsidiaries (including their overseas subsidiaries) had a total of approximately $5.3 billion in exposure as of March 31, 2014, which decreased to $3.5 billion as of March 31, 2015. Our principal banking subsidiaries (including their overseas subsidiaries) had no exposure to obligors in Ukraine as of March 31, 2014 and 2015. The exposure amounts are on a managerial accounting basis, and footnotes 1 and 2 to the table immediately above are similarly applicable to these amounts.

Critical Accounting Estimates

Note 1 to our consolidated financial statements included elsewhere in this annual report contains a summary of our significant accounting policies. These accounting policies are essential to understanding our financial condition and results of operations. Certain of these accounting policies require management to make critical accounting estimates that involve complex and subjective judgments and the use of assumptions, some of which may be for matters that are inherently uncertain and susceptible to change. Such critical accounting estimates are based on information available to us as of the date of the financial statements and could change from period to period. Critical accounting estimates could also involve estimates for which management could have reasonably used another estimate for the relevant accounting period. The use of different estimates could have a material impact on our financial condition and results of operations. The following is a discussion of significant accounting policies for which critical accounting estimates are used.

Allowance for Loan Losses and Allowance for Losses on Off-Balance-Sheet Instruments

The allowance for loan losses is based on management’s estimate of probable credit losses existing in our lending portfolio, and the allowance for losses on off-balance-sheet instruments is based on management’s estimate of probable losses related to off-balance-sheet arrangements such as guarantees and commitments to extend credit.

The allowance for loan losses is categorized and evaluated using the following methods:

• Allowance based on ASC 310. In accordance with ASC 310, “Receivables” (“ASC 310”), we measure the value of specifically identified impaired loans based on the present value of expected cash flows discounted at the loans’ initial effective interest rate, or as a practical expedient, using the observable market price or the fair value of collateral if the loan is collateral dependent, when it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. The collateral that we obtain for loans consists primarily of real estate or listed securities. In obtaining the collateral, we evaluate the value of the collateral and its legal enforceability, and we also perform subsequent re-evaluations at least once a year. As to collateral of loans that are collateral dependent, in the case of real estate, valuation is generally performed by an appraising subsidiary that is independent from our loan origination sections by using generally accepted valuation techniques such as (i) the replacement cost approach, or (ii) the sales comparison approach or (iii) the income approach, although in the case of large real estate collateral, we generally engage third-party appraisers to perform the valuation. In the case of securities, such securities are typically those of listed companies and observable market prices are used for valuation. Management identifies impaired loans through the credit quality review process, in which the ability of borrowers to service their debt is assessed. The difference between our evaluation of the value of the impaired loan and its principal amount is the amount of the impairment which is recorded in the allowance for loan losses. Estimation of future cash flows is based on a comprehensive analysis of the borrower’s ability to service the debt, any progress made on the borrower’s rehabilitation program and the assumptions used therein.

• Allowance based on ASC 450. In accordance with ASC 450, “Contingencies” (“ASC 450”), a formula-based allowance utilizing historical loss factors is applied to certain impaired loans which are aggregated for purposes of measuring impairment, groups of small balance, homogeneous loans and other non-homogeneous loans that have not been identified as impaired. The determination of expected losses is based on a statistical analysis of our historical default and loan loss data, as well as data from third-party sources. The estimation of the formula allowance is back-tested on a periodic basis by comparing the allowance with the actual results subsequent to the balance sheet date.

• Adjustment of ASC 450 Allowance. In addition to the allowance for loan losses based on historical loss factors, the historical loss rate is adjusted, where appropriate, to reflect current factors, such as general economic and business conditions affecting key lending areas, credit quality trends, specific industry conditions and recent loss experience in the segments of the loan portfolio. For loans which are not

60

deemed to be impaired under ASC 310 but to which special isolated risks apply, management assesses each loan individually to determine appropriate allowance amounts in lieu of mechanically applying the ASC 450 formula-based allowance.

We assess probable loss amounts for guarantees by using the same categories and evaluation methods as loans. We similarly assess probable loss amounts for loan commitments, taking into account the probability of drawdowns.

The determination of the allowance for loan losses and the allowance for losses on off-balance-sheet instruments requires a great deal of judgment and the use of estimates as discussed above. Furthermore, information available at the time of the determination is limited, and it is not possible to eliminate uncertainty. Significant changes in any of the factors underlying our determination of the allowances could materially affect our financial condition and results of operations. For example, if our current judgment with respect to expected future cash flows differs from actual results, including as a result of an unexpected adverse change in the economic environment in Japan or a sudden and unanticipated failure of a large borrower, or if the value of collateral declines, we may need to increase the allowances with additional charges to earnings.

Valuation of Financial Instruments

ASC 820, “Fair Value Measurement” (“ASC 820”) specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. The standard describes the following three levels of inputs that may be used to measure fair value:

Level 1	Quoted prices in active markets for identical assets or liabilities. Level 1 assets and liabilities include debt and equity securities and derivative contracts that are traded in an active exchange market.
Level 2	Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments. If no quoted market prices are available, the fair values of debt securities and over-the-counter derivative contracts in this category are determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data.
Level 3	Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques.

For assets and liabilities classified in Level 1 and 2 of the hierarchy, where inputs are principally based on observable market data, there is less judgment or estimate in determining fair value, while the determination of fair value of Level 3 assets and liabilities involves more significant management judgments and estimates. For further information, including valuation methodologies and the use of management estimates and judgments in connection therewith, see note 27 to the consolidated financial statements included elsewhere in this annual report.

Valuation of Deferred Income Taxes

Deferred income taxes reflect the net tax effects of (1) temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, and (2) operating loss and tax credit carryforwards. Pursuant to ASC 740, “Income Taxes” (“ASC 740”), a valuation allowance is recognized for any portion of the deferred tax assets where it is considered more likely than not that

it will not be realized, based on projected future income, future reversals of existing taxable temporary differences and tax-planning strategies. Because we have not opted to be subject to consolidated taxation, deferred tax assets and liabilities are calculated separately for each member of our consolidated group.

The determination of a valuation allowance is an inherently uncertain process due to the use of projected future taxable income and subjective assessments in the effectiveness of our available tax-planning strategies provided for under ASC 740. Variances in future projected operating performance or tax law changes could result in a change in the valuation allowance. Variances in the net unrealized gains on available-for-sale securities could also affect a change in the valuation allowance, because we consider the sales of available-for-sale securities to be a qualifying tax-planning strategy that is a possible source of future taxable income mainly with respect to our principal banking subsidiaries in Japan. Although we evaluate that this tax-planning strategy is prudent and feasible, it has limitations and risks such as the resulting decrease in net unrealized gains on available-for-sale securities that are available to be utilized in the future. If we are not able to realize all or part of our net deferred tax assets in the future, an adjustment to our valuation allowance would be charged to income tax expense in the period when such determination is made, and this could materially and adversely affect our financial condition and results of operations.

Pension and Other Employee Benefit Plans

Mizuho Financial Group, its principal banking subsidiaries and certain other subsidiaries sponsor severance indemnities and pension plans, which provide defined benefits to retired employees. Periodic expense and accrued liabilities are computed based on a number of actuarial assumptions, including mortality, withdrawals, discount rates, expected long-term rates of return on plan assets and rates of increase in future compensation levels.

Actual results that differ from the assumptions are accumulated and amortized over future periods and therefore generally affect future pension expenses. While management believes that the assumptions used are appropriate, differences in actual experience or changes in assumptions may adversely affect pension expenses in the future.

In estimating the discount rates, we use interest rates on high-quality fixed-income government and corporate bonds that received a rating of AA (Aa) or higher from rating agencies. The durations of such bonds closely match those of the benefit obligations. Assumed discount rates are reevaluated at each measurement date.

The expected rate of return for each asset category is based primarily on various aspects of the long-term prospects for the economy that include historical performance and the market environment.

For further information on our pension and other employee benefits, see note 20 to the consolidated financial statements included elsewhere in this annual report.

Executive Summary

Fiscal Year Ended March 31, 2015 Compared to Fiscal Year Ended March 31, 2014

Net interest income increased by ¥25 billion, or 2.4%, from the previous fiscal year to ¥1,046 billion in the fiscal year ended March 31, 2015 due to an increase in net foreign interest and dividend income of ¥69 billion, offset in part by a decrease in net domestic interest and dividend income of ¥44 billion. The increase in net foreign interest and dividend income was due mainly to increases in interest income from foreign loans and foreign investments as a result of an increase in average balance, mainly in Americas and Asia. The decrease in net domestic interest and dividend income was due mainly to decreases in interest income from domestic loans as a result of a decrease in the average yield, and domestic investments as a result of a decrease in interest income on interest on securities, both reflecting declines in interest rate levels of yen. Credit for loan losses decreased by ¥66 billion from the previous fiscal year to ¥60 billion in the fiscal year ended March 31, 2015 due primarily to an increase in allowance for loan losses on impaired loans related to certain domestic borrowers, although we continued to record a credit for loan losses and recorded a decrease in allowance for loan losses on non-impaired loans as a result of upgrades in the obligor categories of a broad range of borrowers, reflecting the continuing gradual recovery of the Japanese economy.

Noninterest income increased by ¥718 billion, or 66.3%, from the previous fiscal year to ¥1,801 billion in the fiscal year ended March 31, 2015. The increase was due mainly to trading account gains—net of ¥690 billion compared to trading account losses—net of ¥60 billion in the previous fiscal year, offset in part by a decrease in foreign exchange losses—net of ¥35 billion compared to foreign exchange gains—net of ¥26 billion in the previous fiscal year. The change in trading account gains (losses)—net was due mainly to an increase in gains related to changes in the fair value of foreign currency-denominated available-for-sale securities for which the fair value option was elected and an increase in gains related to changes in the fair value of derivative financial instruments used to hedge market risks that are not eligible for hedge accounting under U.S. GAAP. The decrease in foreign exchange gains (losses)—net was due mainly to fluctuations in foreign exchange rates in the fiscal year ended March 31, 2015.

Noninterest expenses increased by ¥135 billion, or 9.0%, from the previous fiscal year to ¥1,639 billion in the fiscal year ended March 31, 2015. The increase was due mainly to increases in general administrative

63

expenses of ¥43 billion, salaries and employee benefits of ¥18 billion and occupancy expenses of ¥17 billion. The increase in general administrative expenses was due mainly to increases in domestic consumption tax, reflecting the rise in the consumption tax rate, IT-related costs and advertising expenses. The increase in salaries and employee benefits was due mainly to an increase in overseas personnel expenses, offset in part by a decrease in employee retirement benefit expenses. The increase in occupancy expenses was due mainly to increases in rent expenses and depreciation expenses of tangible fixed assets.

As a result of the foregoing, income before income tax expense increased by ¥542 billion, or 74.7%, from the previous fiscal year to ¥1,268 billion in the fiscal year ended March 31, 2015. Income tax expense increased by ¥212 billion from the previous fiscal year to ¥438 billion in the fiscal year ended March 31, 2015, due to increases in both current tax expense and deferred tax expense.

Net income increased by ¥330 billion, or 66.0%, from the previous fiscal year to ¥830 billion in the fiscal year ended March 31, 2015. Net income attributable to noncontrolling interests increased by ¥25 billion from the previous fiscal year to ¥27 billion in the fiscal year ended March 31, 2015. As a result, net income attributable to MHFG shareholders increased by ¥305 billion, or 61.2%, from the previous fiscal year to ¥803 billion in the fiscal year ended March 31, 2015.

Fiscal Year Ended March 31, 2014 Compared to Fiscal Year Ended March 31, 2013

Net interest income increased by ¥10 billion, or 1.0%, from the previous fiscal year to ¥1,021 billion in the fiscal year ended March 31, 2014 due to an increase in net foreign interest and dividend income of ¥60 billion, offset in part by a decrease in net domestic interest and dividend income of ¥50 billion. The increase in net foreign interest and dividend income was due mainly to an increase in interest income from foreign loans as a result of an increase in the average balance, mainly in Asia, offset in part by an increase in interest expense on foreign deposits as a result of an increase in the average balance and an increase in interest expense on foreign trading account liabilities as a result of an increase in the average interest rate, reflecting a rise in long-term interest rate levels of major currencies, as well as an increase in the average balance. The decrease in net domestic interest and dividend income was due mainly to a decrease in interest income from domestic loans as a result of a decrease in the average yield, reflecting a decline in short-term interest rate levels of yen and a decrease in interest and dividend income from domestic investments as a result of a decrease in the average balance as a result of sales and redemptions of Japanese government bonds. These effects were offset in part by a decrease in interest expense on domestic short-term borrowings as a result of a decrease in the average balance and a decrease in the average rate, reflecting a decline in short-term interest rate levels of yen. We recorded a credit for loan losses of ¥126 billion in the fiscal year ended March 31, 2014 compared to a provision for loan losses of ¥140 billion in the previous fiscal year. The change was due primarily to a decrease in allowance for loan losses on domestic impaired loans as a result of upgrades and collections related to some borrowers and allowance for loan losses on non-impaired loans reflecting upgrades in the obligor categories of a broad range of borrowers mainly through our credit management activities, including business revitalization support for borrowers, reflecting the continuing gradual recovery of the Japanese economy.

Noninterest income decreased by ¥356 billion, or 24.7%, from the previous fiscal year to ¥1,083 billion in the fiscal year ended March 31, 2014. The decrease was due mainly to trading account losses—net of ¥60 billion compared to trading account gains—net of ¥534 billion in the previous fiscal year, offset in part by an increase in investment gains—net of ¥145 billion and an increase in fee and commission income of ¥63 billion. The change in trading account gains (losses)—net was due mainly to an increase in losses related to changes in the fair value of foreign currency-denominated available-for-sale securities for which the fair value option was elected and an increase in losses related to changes in the fair value of derivative financial instruments used to hedge market risks that are not eligible for hedge accounting under U.S. GAAP. The increase in investment gains—net was due mainly to an increase in investment gains related to equity securities and other investment gains recorded in the fiscal year ended March 31, 2014 compared to other investment losses in the previous fiscal year, offset in part by a decrease in investment gains related to bonds. The increase in investment gains related to equity securities

64

was due mainly to a decrease in impairment losses on equity securities and an increase in gains on sales of equity securities, both of which were results of an upturn in domestic stock market conditions. The decrease in investment gains related to bonds was due mainly to a decrease in gains on sales of bonds, which reflected a rise in long-term interest rates of the yen and certain other major currencies. The increase in fee and commission was due mainly to an increase in fee and commission from securities-related business, as a result of upturn in domestic stock markets, and an increase in fees for other customer services.

Noninterest expenses increased by ¥79 billion, or 5.5%, from the previous fiscal year to ¥1,504 billion in the fiscal year ended March 31, 2014. The increase was due mainly to an increase in general and administrative expenses of ¥47 billion and an increase in salaries and employee benefits of ¥15 billion. The increase in general and administrative expenses was due mainly to increases in IT-related costs and advertising expenses. The increase in salaries and employee benefits was due mainly to an increase in overseas personnel expenses, offset in part by the effect of decreased employee retirement benefit expenses.

As a result of the foregoing, income before income tax expense decreased by ¥159 billion, or 18.0%, from the previous fiscal year to ¥726 billion in the fiscal year ended March 31, 2014. Income tax expense increased by ¥222 billion from the previous fiscal year to ¥226 billion in the fiscal year ended March 31, 2014 due mainly to deferred tax expense of ¥90 billion compared to deferred tax benefit of ¥44 billion in the previous fiscal year and an increase in current tax expense of ¥88 billion.

Net income decreased by ¥381 billion, or 43.2%, from the previous fiscal year to ¥500 billion in the fiscal year ended March 31, 2014. Net income attributable to noncontrolling interests decreased by ¥4 billion, or 66.7% from the previous fiscal year to ¥2 billion in the fiscal year ended March 31, 2014. As a result, net income attributable to MHFG shareholders decreased by ¥377 billion, or 43.1%, from the previous fiscal year to ¥498 billion in the fiscal year ended March 31, 2014.

Fiscal Year Ended March 31, 2015 Compared to Fiscal Year Ended March 31, 2014

Interest and dividend income increased by ¥35 billion, or 2.5%, from the previous fiscal year to ¥1,458 billion in the fiscal year ended March 31, 2015. Domestic interest and dividend income accounted for ¥780 billion of the total amount, a decrease of ¥53 billion from the previous fiscal year, and foreign interest and dividend income accounted for ¥678 billion, an increase of ¥88 billion from the previous fiscal year.

The decrease in domestic interest and dividend income was due mainly to decreases in interest income from domestic loans and in interest and dividend income from domestic investments. The decrease in interest income from domestic loans was due mainly to a decrease in the average yield, and the decrease in interest and dividend income from domestic investments was due mainly to a decrease in interest income on interest on securities, both reflecting declines in interest rate levels of yen. Changes in the average yields on domestic interest-earning assets contributed to an overall decrease in interest and dividend income of ¥48 billion, and changes in the average balances of domestic interest-earning assets contributed to an overall decrease in interest and dividend income of ¥5 billion, resulting in the ¥53 billion decrease in domestic interest and dividend income.

The increase in foreign interest and dividend income was due mainly to increases in interest income from foreign loans and in interest and dividend income from foreign investments. The increases in interest income from foreign loan and interest and dividend income from foreign investments were due mainly to an increase in the average balance mainly in Americas and Asia. Changes in the average yields on foreign interest-earning assets contributed to an overall decrease in interest and dividend income of ¥18 billion, and changes in the average balance of foreign interest-earning assets contributed to an overall increase of ¥106 billion, resulting in the ¥88 billion increase in foreign interest and dividend income.

Interest expense increased by ¥10 billion, or 2.5%, from the previous fiscal year to ¥412 billion in the fiscal year ended March 31, 2015. Domestic interest expense accounted for ¥263 billion of the total amount, a decrease of ¥9 billion from the previous fiscal year, and foreign interest expense accounted for ¥149 billion of the total amount, an increase of ¥19 billion from the previous fiscal year.

The decrease in domestic interest expense was due mainly to decreases in interest expense on domestic short-term borrowings, domestic deposits and long-term debt. The decrease in interest expense on domestic short-term borrowings was due mainly to decreases in the average balance and in the average interest rate, reflecting a decline in short-term interest rate levels of yen. The decreases in domestic deposits and long-term debt were due mainly to a decrease in the average yields reflecting a decline in interest rate levels of yen, offset in part by the effect of an increase in the average balance of long-term debt. The changes in the average interest rates on domestic interest-bearing liabilities contributed to an overall decrease in interest expense of ¥46 billion, and the changes in the average balance of domestic interest-bearing liabilities contributed to an overall increase in interest expense of ¥37 billion, resulting in the ¥9 billion decrease in domestic interest expense.

The increase in foreign interest expense was due mainly to an increase in interest expense on foreign deposits. The increase in foreign interest expense on foreign deposits was due mainly to an increase in the average balance. The changes in the average interest rates on foreign interest-bearing liabilities contributed to an overall decrease in interest expense of ¥8 billion, and the changes in the average balance of foreign interest-bearing liabilities contributed to an overall increase in interest expense of ¥27 billion, resulting in the ¥19 billion increase in foreign interest expense.

As a result of the foregoing, net interest income increased by ¥25 billion, or 2.4%, from the previous fiscal year to ¥1,046 billion. The average interest rate spread declined by 0.01% from the previous fiscal year to 0.61% in the fiscal year ended March 31, 2015. The decline of the average interest rate spread was not significant because both the average yields on total interest-earning assets and the average interest rates on total interest-bearing liabilities generally leveled out between these periods.

67

Fiscal Year Ended March 31, 2014 Compared to Fiscal Year Ended March 31, 2013

Interest and dividend income was ¥1,423 billion in the fiscal year ended March 31, 2014, which was the same level as the previous fiscal year. Domestic interest and dividend income accounted for ¥833 billion of the total amount, a decrease of ¥61 billion from the previous fiscal year, and foreign interest and dividend income accounted for ¥590 billion, an increase of ¥61 billion from the previous fiscal year.

The decrease in domestic interest and dividend income was due mainly to decreases in interest income from domestic loans and in interest and dividend income from domestic investments. The decrease in interest income from domestic loans was due mainly to a decrease in the average yield, reflecting a decline in short-term interest rate levels of yen, offset in part by the effect of an increase in the average balance of domestic loans. The decrease in interest and dividend income from domestic investments was due mainly to a decrease in the average balance of domestic investments as a result of sales and redemptions of Japanese government bonds. Changes in the average yields on domestic interest-earning assets contributed to an overall decrease in interest and dividend income of ¥52 billion, and changes in the average balances of domestic interest-earning assets contributed to an overall decrease in interest and dividend income of ¥9 billion, resulting in the ¥61 billion decrease in domestic interest and dividend income.

The increase in foreign interest and dividend income was due mainly to an increase in interest income from foreign loans, offset in part by decreases in interest income from foreign call loans and funds sold, and receivable under resale agreements and securities borrowing transactions and in interest income from foreign trading account assets. The increase in interest income from foreign loans was due mainly to an increase in the average balance, mainly in Asia. The decreases in interest income from call loans and funds sold, and receivable under resale agreements and securities borrowing transactions and in interest income from foreign trading account assets were due mainly to a decrease in average yield, reflecting a decline in short-term interest rate levels of major currencies. Changes in the average yields on foreign interest-earning assets contributed to an overall decrease in interest and dividend income of ¥15 billion, and changes in the average balance of foreign interest-earning assets contributed to an overall increase in interest and dividend income of ¥76 billion, resulting in the ¥61 billion increase in foreign interest and dividend income.

Interest expense decreased by ¥10 billion, or 2.4%, from the previous fiscal year to ¥402 billion in the fiscal year ended March 31, 2014. Domestic interest expense accounted for ¥272 billion of the total amount, a decrease of ¥11 billion from the previous fiscal year, and foreign interest expense accounted for ¥130 billion of the total amount, an increase of ¥1 billion from the previous fiscal year.

The decrease in domestic interest expense was due mainly to a decrease in interest expense on domestic short-term borrowings, offset in part by an increase in interest expense on long-term debt. The decrease in interest expense on domestic short-term borrowings was due mainly to a decrease in the average balance and a decrease in the average interest rate, reflecting a decline in short-term interest rate levels of yen. The increase in interest expense on long-term debt was due mainly to an increase in the average balance, offset in part by a decrease in the average interest rates as a result of an increase in low interest rate debt from the Bank of Japan. The changes in the average interest rates on domestic interest-bearing liabilities contributed to an overall decrease in interest expense of ¥22 billion, and the changes in the average balance of domestic interest-bearing liabilities contributed to an overall increase in interest expense of ¥11 billion, resulting in the ¥11 billion decrease in domestic interest expense.

The increase in foreign interest expense was due mainly to increases in interest expense on foreign deposits and foreign trading account liabilities, offset in part by a decrease in interest expense on foreign short-term borrowings. The increase in foreign interest expense on foreign deposits was due mainly to an increase in the average balance. The increase in interest expense on foreign trading account liabilities was due mainly to an increase in the average interest rate, reflecting a rise in long-term interest rate levels of major currencies, as well as an increase in the average balance. The decrease in foreign interest expense on foreign short-term borrowings was due mainly to a decrease in the average interest rate, reflecting a decline in short-term interest rate levels of

68

major currencies. The changes in the average interest rates on foreign interest-bearing liabilities contributed to an overall decrease in interest expense of ¥25 billion, and the changes in the average balance of foreign interest-bearing liabilities contributed to an overall increase in interest expense of ¥26 billion, resulting in the ¥1 billion increase in foreign interest expense.

As a result of the foregoing, net interest income increased by ¥10 billion, or 1.0%, from the previous fiscal year to ¥1,021 billion. The average interest rate spread declined by 0.01% from the previous fiscal year to 0.62% in the fiscal year ended March 31, 2014. The decline of the average interest rate spread was not significant because both the average yields on total interest-earning assets and the average interest rates on total interest-bearing liabilities generally leveled out between these periods.

Provision (Credit) for Loan Losses

Fiscal Year Ended March 31, 2015 Compared to Fiscal Year Ended March 31, 2014

Credit for loan losses decreased by ¥66 billion from the previous fiscal year to ¥60 billion in the fiscal year ended March 31, 2015 due primarily to an increase in allowance for loan losses on impaired loans related to certain domestic borrowers, although we continued to record a credit for loan losses and recorded a decrease in allowance for loan losses on non-impaired loans as a result of upgrades in the obligor categories of a broad range of borrowers, reflecting the continuing gradual recovery of the Japanese economy.

Fiscal Year Ended March 31, 2014 Compared to Fiscal Year Ended March 31, 2013

We recorded a credit for loan losses of ¥126 billion in the fiscal year ended March 31, 2014 compared to a provision for loan losses of ¥140 billion in the previous fiscal year. The change was due primarily to a decrease in allowance for loan losses on domestic impaired loans as a result of upgrades and collections related to some borrowers and allowance for loan losses on non-impaired loans reflecting upgrades in the obligor categories of a broad range of borrowers mainly through our credit management activities, including business revitalization support for borrowers, reflecting the continuing gradual recovery of the Japanese economy as described in “—Overview—Operating Environment.”

The increase was due mainly to trading account gains—net of ¥690 billion compared to trading account losses—net of ¥60 billion in the previous fiscal year, offset in part by a decrease in foreign exchange losses—net of ¥35 billion compared to foreign exchange gains—net of ¥26 billion in the previous fiscal year.

Fee and commission

Fee and commission increased by ¥40 billion, or 5.9%, from the previous fiscal year to ¥716 billion in the fiscal year ended March 31, 2015. The increase was due mainly to an increase in fee and commission from deposits and lending business of ¥17 billion and an increase in fees for other customer services of ¥19 billion. The increase in fee and commission from deposits and lending business was due mainly to our increased involvement in large overseas transactions, and the increase in fee and commission from other customer services was due mainly to an increase in fees related to real estate in the trust and asset management business of a principal banking subsidiary.

Foreign exchange gains (losses)—net

Foreign exchange gains (losses)—net was a loss of ¥35 billion in the fiscal year ended March 31, 2015 compared to a gain of ¥26 billion in the previous fiscal year. The change was due mainly to fluctuations in foreign exchange rates in the fiscal year ended March 31, 2015.

Trading account gains (losses)—net

Trading account gains (losses)—net was a gain of ¥690 billion in the fiscal year ended March 31, 2015 compared to a loss of ¥60 billion in the previous fiscal year. The change was due mainly to an increase in gains related to changes in the fair value of foreign currency-denominated available-for-sale securities for which the fair value option was elected, reflecting a decline in long-term interest rates, and an increase in gains related to changes in the fair value of derivative financial instruments used to hedge market risks, mainly interest rate risks, that are not eligible for hedge accounting under U.S. GAAP. For further information on the fair value option, see note 27 to our consolidated financial statements included elsewhere in this annual report.

Investment gains (losses)—net

Investment gains—net increased by ¥33 billion, or 13.9%, from the previous fiscal year to ¥271 billion in the fiscal year ended March 31, 2015. The increase was due mainly to an increase in investment gains related to bonds of ¥44 billion, or 73.3%, from the fiscal year ended March 31, 2014 to ¥104 billion in the fiscal year ended March 31, 2015, offset in part by a decrease in investment gains related to equity securities of ¥12 billion, or 6.9%, from the fiscal year ended March 31, 2014 to ¥163 billion in the fiscal year ended March 2015. The increase in investment gains related to bonds was due mainly to an increase in gains on sales of bonds in the fiscal year ended March 31, 2015 as a result of a decline in long-term interest rates. The decrease in investment gains related to equity securities was due mainly to a decrease in gains on sales of investment account equity securities in the fiscal year ended March 31, 2015.

Fiscal Year Ended March 31, 2014 Compared to Fiscal Year Ended March 31, 2013

Noninterest income decreased by ¥356 billion, or 24.7%, from the previous fiscal year to ¥1,083 billion in the fiscal year ended March 31, 2014. The decrease was due mainly to trading account losses—net of ¥60 billion compared to trading account gains—net of ¥534 billion in the previous fiscal year, offset in part by an increase in investment gains—net of ¥145 billion and an increase in fee and commission income of ¥63 billion.

70

Fee and commission

Fee and commission increased by ¥63 billion, or 10.3%, from the previous fiscal year to ¥676 billion in the fiscal year ended March 31, 2014. The increase was due mainly to an increase in fee and commission from securities-related business of ¥37 billion and an increase in fees for other customer services of ¥19 billion. The increase in fee and commission from securities-related business was due mainly to an increase in fee and commission related to investment trusts and individual annuities as a result of the upturn in domestic stock markets during the fiscal year ended March 31, 2014 compared to the previous fiscal year.

Trading account gains (losses)—net

Trading account gains (losses)—net was a loss of ¥60 billion in the fiscal year ended March 31, 2014 compared to a gain of ¥534 billion in the previous fiscal year. The change was due mainly to an increase in losses related to changes in the fair value of foreign currency-denominated available-for-sale securities for which the fair value option was elected, reflecting a rise in long-term interest rates, and an increase in losses related to changes in the fair value of derivative financial instruments used to hedge market risks, mainly interest rate risks, that are not eligible for hedge accounting under U.S. GAAP. For further information on the fair value option, see note 27 to our consolidated financial statements included elsewhere in this annual report.

Investment gains (losses)—net

Investment gains—net increased by ¥115 billion, or 93.5%, from the previous fiscal year to ¥238 billion in the fiscal year ended March 31, 2014. The increase was due mainly to an increase in investment gains related to equity securities of ¥119 billion, offset in part by a decrease in investment gains related to bonds of ¥31 billion. The increase in investment gains related to equity securities was due mainly to a decrease in impairment losses on equity securities and an increase in gains on sales of equity securities, both of which were results of an upturn in domestic stock market conditions during the fiscal year ended March 31, 2014. The decrease in investment gains related to bonds was due mainly to a decrease in gains on sales of bonds in the fiscal year ended March 31, 2014, which reflected a rise in long-term interest rates of the yen and certain other major currencies during the fiscal year ended March 31, 2014 compared to the previous fiscal year.

Total noninterest expenses	¥	1,425	¥	1,504	¥	1,639

Fiscal Year Ended March 31, 2015 Compared to Fiscal Year Ended March 31, 2014

Noninterest expenses increased by ¥135 billion, or 9.0%, from the previous fiscal year to ¥1,639 billion in the fiscal year ended March 31, 2015. The increase was due mainly to an increase in general and administrative expenses of ¥43 billion, an increase in salaries and employee benefit expenses of ¥18 billion and an increase in occupancy expenses of ¥17 billion.

71

Salaries and employee benefits

Salaries and employee benefits increased by ¥18 billion, or 3.1%, from the previous fiscal year to ¥605 billion in the fiscal year ended March 31, 2015 due mainly to an increase in personnel expenses, offset in part by a decrease in employee retirement benefit expenses. The increase in personnel expenses was due mainly to an increase in overseas personnel expenses, which partly reflected the depreciation of the yen against other major currencies. The decrease in employee retirement benefit expenses was due mainly to a decrease in interest costs on projected benefit obligation, which primarily reflects past decline in discount rate and a decrease in the amortization of net actuarial loss, which primarily reflects past recoveries of the fair value of plan assets. Additional information regarding pension and other employee benefit plans is included in note 20 to our consolidated financial statements included elsewhere in this annual report.

General and administrative expenses

General and administrative expenses increased by ¥43 billion, or 8.8%, from the previous fiscal year to ¥530 billion in the fiscal year ended March 31, 2015. The increase was due mainly to increases in domestic consumption tax, reflecting the rise in the consumption tax rate, IT-related costs and advertising expenses.

Occupancy expenses

Occupancy expenses increased by ¥17 billion, or 9.9%, from the previous fiscal year to ¥189 billion in the fiscal year ended March 31, 2015. The increase was due mainly to increases in rent expenses and depreciation expenses of tangible fixed assets.

Fiscal Year Ended March 31, 2014 Compared to Fiscal Year Ended March 31, 2013

Noninterest expenses increased by ¥79 billion, or 5.5%, from the previous fiscal year to ¥1,504 billion in the fiscal year ended March 31, 2014. The increase was due mainly to an increase in general and administrative expenses of ¥47 billion and an increase in salaries and employee benefits of ¥15 billion.

Salaries and employee benefits

Salaries and employee benefits increased by ¥15 billion, or 2.6%, from the previous fiscal year to ¥587 billion in the fiscal year ended March 31, 2014. The increase was due mainly to an increase in overseas personnel expenses, offset in part by the effects of decreased employee retirement benefit expenses as a result of a decrease in the amortization of net actuarial loss, which primarily reflects past recoveries of the fair value of plan assets and an increase in expected return on plan assets, which reflects various aspects of long-term prospects for the economy, historical performance of investments of plan assets and the market environment, including stock market conditions, at the beginning of the fiscal year. Additional information regarding pension and other employee benefit plans is included in note 20 to our consolidated financial statements included elsewhere in this annual report.

General and administrative expenses

General and administrative expenses increased by ¥47 billion, or 10.7%, from the previous fiscal year to ¥487 billion in the fiscal year ended March 31, 2014. The increase was due mainly to an increase in IT-related costs as a result of the commencement of depreciation relating to the common operational infrastructure of the new IT systems platform, as well as an increase in overseas and advertising expenses.

Income Tax Expense

The following table shows the components of income tax expense (benefit) for the fiscal years ended March 31, 2013, 2014 and 2015:

	Fiscal years ended March 31,

Total income tax expense	¥	4		¥	226		¥	438

Fiscal Year Ended March 31, 2015 Compared to Fiscal Year Ended March 31, 2014

Income tax expense increased by ¥212 billion from the previous fiscal year to ¥438 billion in the fiscal year ended March 31, 2015, due to an increase in current tax expense of ¥120 billion and an increase in deferred tax expense of ¥92 billion. The increase in current tax expense was due mainly to an increase in the taxable income of a principal banking subsidiary. The increase in deferred tax expense was due mainly to accelerated decreases in the temporary differences of our subsidiaries, offset in part by a benefit caused by tax rate reductions.

We consider the sales of available-for-sale securities to be a qualifying tax-planning strategy that is possible source of future taxable income to the extent necessary in the future mainly with respect to our principal banking subsidiaries in Japan. Our principal banking subsidiaries in Japan reduced the reliance on this tax-planning strategy from approximately one-fifth to immaterial levels of overall deferred tax assets during the fiscal year ended March 31, 2015, due mainly to the aforementioned decreases in the temporary differences of our subsidiaries, while the reliance was reduced from approximately one-third to approximately one-fifth of overall deferred tax assets during the fiscal year ended March 31, 2014.

Fiscal Year Ended March 31, 2014 Compared to Fiscal Year Ended March 31, 2013

Income tax expense increased by ¥222 billion from the previous fiscal year to ¥226 billion in the fiscal year ended March 31, 2014 due mainly to deferred tax expense of ¥90 billion compared to deferred tax benefit of ¥44 billion in the previous fiscal year and an increase in current tax expense of ¥88 billion.

We consider the sales of available-for-sale securities to be a qualifying tax-planning strategy that is possible source of future taxable income to the extent necessary in the future mainly with respect to our principal banking subsidiaries in Japan. In the fiscal year ended March 31, 2013, deferred tax assets, net of valuation allowance, increased with a corresponding net deferred tax benefit that resulted from the significant increase in net unrealized gains on available-for-sale securities which led to a reduction of valuation allowance for our principal banking subsidiaries in Japan. In the fiscal year ended March 31, 2014, deferred tax assets, net of valuation allowance, decreased with a corresponding net deferred tax expense. With regard to our principal banking subsidiaries in Japan, this overall deferred tax impact was the result of deferred tax expense arising from the decrease in gross deductible temporary differences in excess of the deferred tax benefit arising from the release of valuation allowance. In turn, this valuation allowance release was caused by the combined impact of a decrease in gross deductible temporary differences and a further increase in net unrealized gains on available-for-sale securities. Our principal banking subsidiaries in Japan reduced the reliance on this tax-planning strategy

73

from approximately one-third to approximately one-fifth of overall deferred tax assets during the fiscal year ended March 31, 2014, while there was no significant change in such reliance during the fiscal year ended March 31, 2013. The increase in current tax expense was due mainly to an increase in the taxable income of a principal banking subsidiary.

Business Segments Analysis

Our operating segments are based on the nature of the products and services provided, the type of customer and our management organization. The business segment information set forth below is derived from the internal management reporting systems used by management to measure the performance of our business segments. We measure the performance of each of our operating segments primarily in terms of “net business profits” in accordance with internal managerial accounting rules and practices. Net business profits is used in Japan as a measure of the profitability of core banking operations and is defined as gross profits (or the sum of net interest income, fiduciary income, net fee and commission income, net trading income and net other operating income) less general and administrative expenses. Measurement of net business profits is required for regulatory reporting to the Financial Services Agency. Therefore, the format and information are presented primarily on the basis of Japanese GAAP and are not consistent with the consolidated financial statements prepared in accordance with U.S. GAAP. A reconciliation of total net business profits with income before income tax expense under U.S. GAAP is provided in note 30 to our consolidated financial statements included elsewhere in this annual report.

We engage in banking, trust banking, securities and other businesses through consolidated subsidiaries and affiliates. As these subsidiaries and affiliates are in different industries and regulatory environments, we disclose business segment information based on the relevant principal consolidated subsidiaries such as Mizuho Bank (the former Mizuho Bank and the former Mizuho Corporate Bank), Mizuho Trust & Banking and Mizuho Securities for investors to measure the present and future cash flows properly.

The operating segments of Mizuho Bank are aggregated based on the type of customer characteristics and are aggregated into the following seven reportable segments: Personal Banking; Retail Banking; Corporate Banking (Large Corporations); Corporate Banking; Financial Institutions & Public Sector Business; International Banking; and Trading and others.

For a brief description of our each business segment, see note 30 to our consolidated financial statements included elsewhere in this annual report.
