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 or current expectationsof our management with respect to our financial condition and future results of operations. In many cases, but notall, 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 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 andthe impact of the dislocation in the global financial markets;3•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 Management Policy and other strategic initiatives andmeasures 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 anduncertainties. 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. Informationon 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) Net income (loss) attributable to noncontrolling interests was relocated from minority interest in consolidated
subsidiaries included within noninterest expenses in the fiscal year ended March 31, 2010 as we adopted ASC 810. For
purposes of comparability, the figures of the previous fiscal years are adjusted accordingly.
(2) Under the central book-entry transfer system in Japan, which became effective in January 2009, fractional shares are noteligible for book-entry transfer. Accordingly, an allotment of shares or fractions of a share without consideration wasmade to all shareholders and holders of fractional shares at the rate of 999 shares per 1 share and 9.99 shares per every
0.01 of a share, effective on January 4, 2009. The amounts per share for the fiscal years ended March 31, 2006, 2007,2008 and 2009 have been adjusted to reflect such allotment.
(3) Yen amounts for cash dividends per share for the fiscal years ended March 31, 2006, 2007, 2008, 2009 and 2010 are
expressed in U.S. dollars at the rate of ¥117.48 = $1.00, ¥117.56 = $1.00, ¥99.85 = $1.00, ¥99.15 = $1.00 and ¥93.40 =$1.00, respectively. These rates are the noon buying rates on March 31, 2006, 2007, 2008, 2009 and 2010 in New York
City for cable transfers in yen as certified for customs purposes by the Federal Reserve Bank of New York.

Under Japanese GAAP, refund of income taxes formerly included within current income taxes is separately presented
from the fiscal year ended March 31, 2010 due to increased materiality. Current income taxes for the fiscal year ended
March 31, 2010 in the above table include refund of income taxes for purposes of comparability with figures fromprevious years.
In accordance with certain amendments to Regulation on Terminology, Forms and Preparation of Financial Statements
and other regulations which may be applied at our option from the fiscal year ended March 31, 2010, based on“Accounting Standard for Consolidated Financial Statements” (ASBJ Statement No. 22, December 26, 2008), we havestarted to present “Income before minority interests” from the fiscal year ended March 31, 2010. For reference
purposes, we have also included the figures of the same for the fiscal years ended March 31, 2006, 2007, 2008 and2009 in the table above.
Under the central book-entry transfer system in Japan, which became effective in January 2009, fractional shares are
not eligible for book-entry transfer. Accordingly, an allotment of shares or fractions of a share without consideration
was made to all shareholders and holders of fractional shares at the rate of 999 shares per 1 share and 9.99 shares per
every 0.01 of a share, effective on January 4, 2009. Net income (loss) per share through the fiscal year ended
March 31, 2008, and cash dividends per share declared through the fiscal year ended March 31, 2009, in the table
above do not reflect such allotment.
Diluted net income per share is not shown due to net loss per share for the fiscal year ended March 31, 2009.
Yen amounts are expressed in U.S. dollars at the rate of, ¥117.48 = $1.00, ¥117.56 = $1.00, ¥99.85 = $1.00,¥99.15 = $1.00 and ¥93.40 = $1.00 for the fiscal years ended March 31, 2006, 2007, 2008, 2009 and 2010,
respectively. These rates are the noon buying rates on the respective fiscal year-end dates in New York City for cabletransfers in yen as certified for customs purposes by the Federal Reserve Bank of New York.
In June 2010, we declared and paid annual dividends of ¥8 per share of common stock, ¥20 per share of eleventh seriesclass XI preferred stock and ¥30 per share of thirteenth series class XIII preferred stock for the fiscal year ended
March 31, 2010.
Bills discounted refers to a form of financing in Japan under which promissory notes obtained by corporations throughtheir regular business activities are purchased by banks prior to their payment dates at a discount based on prevailinginterest rates.
Includes negotiable certificates of deposit.
On December 9, 2005, the Accounting Standards Board of Japan issued a new accounting standard for presentation of
net assets in the balance sheet, which is effective for fiscal years ending on or after May 1, 2006. Under the new
accounting standard, the line item previously presented as “shareholders’ equity” is now presented as “net assets,” andthe line items “minority interests” and “net deferred hedge gains or losses, net of taxes” are now presented ascomponents of net assets. Accordingly, the presentations of net assets in the balance sheets as of March 31, 2007, 2008,2009 and 2010 are not directly comparable to the presentation of shareholders’ equity in the balance sheet as ofMarch 31, 2006.

Risk-adjusted capital data for the fiscal years ended March 31, 2007, 2008, 2009 and 2010 were calculated under BaselII basis while those through the fiscal year ended March 31, 2006 were calculated under Basel I basis. We adopted theadvanced internal ratings-based approach (the “AIRB approach”) for the calculation of risk-weighted assets associatedwith 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
FSA 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, real estate sales and leasebacks, land revaluation, business combinations,non-interest-earning deposits made under government-led restructuring, pension liabilities, consolidation ofvariable interest entities and deferred taxes. See “Item 5. Operating and Financial Review andProspects—Reconciliation with Japanese GAAP.” In addition, under Japanese GAAP, a restatement of prior year
financial statements reflecting the effect of a change in accounting principles is not permitted, unlike under U.S.
GAAP, which generally requires a restatement upon a voluntary change in accounting principles.

10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 andrelated 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 thefactors 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 therisks faced by us described below and elsewhere in this annual report. See “Forward-Looking Statements.”
Risks Relating to Our BusinessWe 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 realestate, banks and other financial institutions, and wholesale and retail industries is relatively high. We manage ourcredit 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 alsoutilize credit derivatives for hedging and credit risk mitigation purposes. In addition, we regularly assess the valueof collateral and guarantees. However, depending on trends in the domestic and global economic environment, thebusiness 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 weare the primary bank lender, other major customers or customers belonging to industries to which we havesignificant credit exposure, and the value of collateral and guarantees could decline. For example, in the fiscal year
ended March 31, 2009, our credit-related costs increased as a result of the deteriorating performance of ourcorporate customers in and outside of Japan due to the worsening economic environment and the effects of thedislocation in global financial markets as well as the provision for loan losses based on revised assumptions amid
the uncertainty regarding the future economic environment. There can be no assurance that credit-related and othercosts 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 listedcompanies. In addition to the partial hedges that we apply as we deem necessary in recent years, we sold aportion of such investments, and we may make further sales in the future. However, significant declines inJapanese 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.
For example, in the fiscal year ended March 31, 2009, we incurred significant impairment and other losses as aresult of the decline in Japanese and other stock markets. In addition, net unrealized gains and losses on suchinvestments, 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 suchinvestments would negatively affect such ratios. As a result, 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,
11

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 utilizationof derivatives and other hedging methods to reduce our exposure to interest rate risk. However, in the event ofsignificant changes in interest rates, including as a result of a change in Japanese monetary policy 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.
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. For example, in thefiscal years ended March 31, 2008 and 2009, we incurred significant losses related to declines in the value of ourinvestments in securitization products and other assets as a result of significant decrease in the market liquidity
amidst the dislocation in global financial markets. See “Item 5. Operating and Financial Review and Prospects—
Overview—Business Trends.” If the market liquidity of our assets decreases significantly in the future, including
as a result of the dislocation in global financial markets mentioned above, our financial condition and results ofoperations 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 andprojected benefit obligations. As a result, our financial condition and results of operations could be materiallyand adversely affected.
A decline in deferred tax assets due to a change in our estimation of future taxable income could adversely
affect our financial condition and results of operations.
We recorded deferred tax assets based on a reasonable estimation of future taxable income in accordancewith applicable accounting standards. Our financial condition and results of operations could be materially andadversely affected if our deferred tax assets decline due to a change in our estimation of future taxable income
and other factors.
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 financialtransactions that we enter into for hedging and credit risk mitigation purposes are not always consistent with the12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 aneffect on net income for such period. As a result, our financial condition and results of operations could bematerially and adversely affected during the period.
Failure to maintain capital adequacy ratios above minimum required levels, as a result of thematerialization 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 tostandards set forth by Japan’s Financial Services Agency and based on Japanese GAAP, taking into account ourplans 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 therisks enumerated in these “Risk Factors” and changes to the methods we use to calculate capital adequacy ratios.
Also, the maximum amount of net deferred tax assets that can be recorded for the purpose of calculating capital
adequacy ratios without diminishing the amount of Tier 1 capital under Japanese capital adequacy regulations is
20% of Tier 1 capital. Our or our banking subsidiaries’ regulatory capital and capital adequacy ratios could
decline due to such regulations.
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 2009, the Basel Committee on
Banking Supervision announced a package of proposals to strengthen global capital and liquidity regulations. See“Item 5. Operating and Financial Review and Prospects—Capital Adequacy.”
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 asuspension of a portion of our business operations. In addition, some of our banking subsidiaries are subject tocapital 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 othersubsidiaries 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.
Our business will be adversely affected if we encounter difficulties in raising funds.
We rely principally on deposits and debentures as our funding sources. In addition, we also raise funds inthe 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 to13

prevent significant increases in our funding costs or 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•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 otherfactors.

Our Medium-term Management Policy 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 May 2010, we announced
our new Medium-term Management Policy for the three fiscal years ending March 31, 2013, in which we set
forth various strategic initiatives and measures and also established a number of key target figures that we aim toachieve by the end of the fiscal year ending March 31, 2013. See “Item 4.B. Business Overview—General.”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 anticipatedeffects. In addition, we may not be able to meet the key target figures announced in the Medium-termManagement Policy 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 Management Policy 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, securities, trust and other services. As theneeds 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 maintainrisk management policies that we believe are appropriate to address such risks, if a risk materializes in a manneror to a degree outside of our expectations, our business, financial condition and results of operations could bematerially and adversely affected.
We are subject to various laws and regulations, and violations could result in penalties and otherregulatory actions.
Our business and employees in Japan are subject to various laws and regulations, including those applicableto 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 thelaws 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 andregulations, but they may not be effective in preventing all future violations. For example, in October 2007,
Mizuho Securities Co., Ltd. received a business improvement order from the Financial Services Agency relating
to the receipt of non-public information from its parent bank and the use of such information for customer
solicitation. 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 riskof various operational errors and misconduct, including those caused by employees. Our measures to reduce14employee errors, including establishment of operational procedures, regular reviews regarding compliance withthese 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 ofoperations could be materially and adversely affected.
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 ourbusiness 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 ofcontingency 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 and development and renewal ofcomputer 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 areunable 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 Law of Japan, may not be effective in preventing all suchproblems. Leakage of important information in the future could result in liabilities and regulatory actions andmay also lead to significant harm to our reputation. As a result, our business, financial condition and results ofoperations 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 andto operate our business efficiently. We may not be successful in attracting and retaining sufficient skilledemployees through our hiring efforts and training programs aimed to maintain and enhance the skills andexpertise 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 ourinternal controls over financial reporting, as required, in our annual report on Form 20-F. In addition, ourmanagement is required to report on our internal control over financial reporting, and our independent registeredpublic accounting firm is required to provide its opinion concerning the report of our management, in accordancewith the Financial Instruments and Exchange Law of Japan. To the extent any issues are identified through theforegoing 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,15

our independent registered public accounting firm may still be unable to issue a report that concludes that ourinternal control over financial reporting are effective. In either case, we may lose investor confidence in thereliability of our financial statements.
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 aresubject 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 unanticipatedrisks.
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 ouruse 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 bematerially and adversely affected.
Transactions with counterparties in Iran and other countries designated by the U.S. Department of Stateas state sponsors of terrorism may lead some potential customers and investors to avoid doing businesswith us or investing in our securities.
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 includes Iran, Cuba,
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,maintenance of correspondent banking accounts and interbank money market transactions. In addition, we
maintain a representative office in Iran and provide project financing to entities in Iran. We also maintaincorrespondent banking accounts for and with, a number of Iranian banks that the U.S. Office of Foreign Assets
Control identifies as “specially designated nationals.” 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.
We are aware of initiatives by U.S. governmental entities and U.S. institutional investors, such as pension
funds, to adopt laws, regulations or policies prohibiting transactions with or investment in, or requiring
divestment from, entities doing business with Iran and other Designated Countries. It is possible that suchinitiatives may result in our being unable to retain or acquire entities that are subject to such prohibitions as
customers or investors in our securities. In addition, depending on socio-political developments, our reputation
may suffer due to our association with the Designated Countries. The above circumstances could have asignificant adverse effect 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 byrequesting 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, theprice of our common stock could decline.
16

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 allof our income. As a result of restrictions, such as those on distributable amounts under Japan’s Company Law, orotherwise, 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
payments on the preferred securities issued by our overseas special purpose companies due to the deterioration of
our results of operations and financial condition and/or the restrictions under the Company Law or due to thestrengthening of bank capital regulations. For more information on restrictions to dividend payments under theCompany Law, 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 andAsia. 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 qualityof our assets. For example, in recent years, we incurred significant losses related to declines in the value of ourinvestments in securitization products, an increase in credit-related costs, an increase in impairment of equity
securities and others as a result of the impact of the dislocation in global financial markets and the worsening
economic environment. 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 andoutside of Japan. We are also subject to various laws and regulations applicable to financial institutions such as
the Banking Law, 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 inbusiness activities that we currently conduct, our business, financial condition and results of operations could bematerially and adversely affected. For example, in December 2009, the Basel Committee on Banking Supervisionannounced a package of proposals to strengthen global capital and liquidity regulations, which could materiallyand adversely affect our business, financial condition and results of operations. See “Item 5. Operating and
Financial Review and Prospects—Capital Adequacy.”
The market for financial services in Japan is increasingly competitive.
Ongoing deregulation in Japan has significantly lowered the barriers to entry with respect to the provision ofbanking, securities, trust and other financial services. While such deregulation has the effect of increasing ourown business opportunities, it also allows other major financial groups, foreign financial institutions, non-bankfinance companies, government-affiliated entities such as Japan Post Bank and other financial services providers
to enter into new business areas or expand existing businesses. As a result, competition in the financial services
industry has been intensifying in recent years and could intensify further in the future. If we are unable torespond effectively to current or future competition, our business, financial condition and results of operations
could be adversely affected.
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 otherfacilities are subject to the risk of damage from natural disasters such as earthquakes and typhoons as well asfrom acts of terrorism and other criminal acts. In addition, our business could be materially disrupted as a resultof an epidemic such as influenza A (H1N1). Our business, financial condition and results of operations could be
adversely affected if our recovery efforts, including our implementation of contingency plans that we havedeveloped such as establishing back-up offices, are not effective in preventing significant disruptions to ourbusiness operations caused by natural disasters and criminal acts.
17

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,
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 Company Law govern our
corporate affairs. Legal principles relating to such matters as the validity of corporate procedures, directors’ andofficers’ fiduciary duties and shareholders’ rights may be different from or less clearly defined than those thatwould apply if we were incorporated in another jurisdiction. For example, under the Company Law, 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 thelaw of jurisdictions within the United States or other countries. For more information on the rights ofshareholders 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, senior management or corporate auditors, 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 theUnited States.
We are a joint stock corporation incorporated under the laws of Japan. Almost all of our directors, senior
management and corporate auditors 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 originalactions 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 andexercising 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 thesame 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 toholders of our ADSs.
Market prices for our ADSs may fall if the value of the yen declines against the U.S. dollar. In addition, theU.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, 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 ourthree predecessor banks were realigned through a corporate split and merger process under Japanese law into awholesale banking subsidiary, Mizuho Corporate Bank, and a banking subsidiary serving primarily retail andsmall and medium-sized enterprise customers, Mizuho Bank. As an additional step for realigning the groupstructure, Mizuho Financial Group was established on January 8, 2003 as a corporation organized under the lawsof 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 theMizuho 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 ofrevitalization or restructuring and to separate the oversight of restructuring borrowers from the normal credit
origination function. In July 2003, our three principal banking subsidiaries, Mizuho Corporate Bank, 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. completed a merger. The merged entity,
Mizuho Securities, is our subsidiary and listed on the Tokyo Stock Exchange and other Japanese stock
exchanges. Through the merger, we aim to improve our service-providing capabilities to our clients and to offer

31

In global markets, we face competition with other commercial banks and other financial institutions,particularly major global banks and the leading domestic 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 July 27, 2010): (i) ordinarybanks, of which there were 127, not including foreign commercial banks with banking operations in Japan; and(ii) trust banks, of which there were 19, including Japanese subsidiaries of foreign financial institutions andsubsidiaries of Japanese financial institutions.
Ordinary banks consist mainly of city banks and regional banks. City banks, including Mizuho Corporate
Bank and Mizuho Bank, are based in large cities, operate domestically on a nation-wide scale through networksof branch offices and have strong links with large corporate customers in Japan. In light of deregulation and othercompetitive 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 the 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 June 28, 2010, there were 58 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 privatebanking institutions, have been in the process of business and organizational restructuring in recent years. In
October 2008, some of the government financial institutions were consolidated to form Japan FinanceCorporation, which mainly provides financing for small and medium-sized enterprises and those engaged inagriculture, 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, whichmainly 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 thesecuritization of such loans.
Another distinctive element of the Japanese banking system was the role of the postal savings system. Postal
savings deposits were gathered through the network of governmental post offices scattered throughout Japan, andtheir 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 wastransferred to Japan Post, a government-owned entity established in the same year, and in 2007, Japan Post wastransformed into a joint stock corporation holding four operating companies including Japan Post Bank, whichcurrently operates as an ordinary bank. Privatization of banking and insurance subsidiaries, which was originallyplanned to be completed by 2017, was suspended in December 2009.
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 thismarket through their subsidiaries. In addition, foreign financial institutions have been active in this market.
32Supervision and Regulation
Japan
Pursuant to the Banking Law (Ginkou Hou) (Law 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 theCommissioner of the Financial Services Agency. The Bank of Japan also has supervisory authority over banks inJapan, 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 bygovernment 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 theCommissioner of the Financial Services Agency and to support the Prime Minister.
Under the Banking Law, 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 inwhole 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 thecase 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 ofits business operations.
Under the prompt warning system introduced in December 2002, the Financial Services Agency may takeprecautionary measures to maintain and promote the sound operations of financial institutions, even before thosefinancial 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 JapanThe Bank of Japan is Japan’s central bank and serves as the principal instrument for the execution ofJapan’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 rediscounting bills with, the Bank ofJapan. Moreover, most banks in Japan maintain current accounts under agreements with the Bank of Japanpursuant 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 andother financial institutions, thereby contributing to the maintenance of an orderly financial system, whereas thesupervisory 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 Law 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 theircompliance 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, theFinancial Services Agency takes the “better regulation” approach in its financial regulation and supervision. Thisconsists 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 and33

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 toindividual 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 ofJapan 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 theirfinancial instruments business activities in accordance with the Financial Instruments and Exchange Law ofJapan (Kinyu Shouhin Torihiki Hou) (Law No. 25 of 1948, as amended).
Examination and Reporting Applicable to Shareholders
Under the Banking Law, 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 suchmeasures as the Financial Services Agency deems necessary.
Furthermore, under the Banking Law, 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 forthin reports previously filed, with some exceptions.
Deposit Insurance System
Under the Deposit Insurance Law (Yokin Hoken Hou) (Law No. 34 of 1971, as amended), depositors areprotected 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 amount of
which is, from April 2010, equivalent to 0.107% of the deposits that bear no interest, are redeemable upon
demand and are used by depositors primarily for payment and settlement purposes, and 0.082% of other deposits.
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 ofprincipal 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 areprotected in full.
Participation in the deposit insurance system is compulsory for city banks (including Mizuho Corporate
Bank and Mizuho Bank), regional banks, long-term credit banks, trust banks (including Mizuho Trust &Banking), credit associations and co-operatives, labor banks and other financial institutions.
34

Governmental Measures to Treat Troubled Institutions
Under the Deposit Insurance Law, 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 betransferred 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 totransfer the bank’s assets to another financial institution or dissolve the bank. The financial aid provided by the
Deposit Insurance Corporation 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 loss sharing. Where it is anticipatedthat the failure of a bank may cause an extremely grave problem in maintaining the financial order in Japan or thearea where such bank is operating, the following measures may be taken: (i) the Deposit Insurance Corporation
may subscribe for the shares or other instruments of the relevant bank in order to enhance capital adequacy of thebank; (ii) if the bank fails or suffers a capital deficit, financial aid exceeding the pay-off cost may be available tosuch bank; and (iii) in the case where the systematic risk cannot be avoided by the measure mentioned in(ii) above, the Deposit Insurance Corporation may acquire the bank’s shares.
Capital Injection by the Government
The Strengthening Financial Functions Law (Kinyu Kinou no Kyouka no tame no Tokubetsu Sochi ni
kansuru Houritsu) (Law No. 128 of 2004) was enacted on June 18, 2004 in order to establish a scheme of publicmoney 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 Law 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 thesoundness of such financial institutions but also loans or other forms of credit extended to small and mediumsized enterprises in order to revitalize local economies.
Bank Holding Companies
Under the Banking Law, a bank holding company is prohibited from carrying out businesses other thanadministrating 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 Law (Shiteki Dokusen no Kinshi oyobi Kousei Torihiki no Kakuho ni kansuru Houritsu)(Law 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 generalshareholding restrictions under the Anti-Monopoly Law. The Banking Law does, however, prohibit a bankholding 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 Law
The Financial Instruments and Exchange Law (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 byquarterly and extraordinary reports.

35

Under the Financial Instruments and Exchange Law, 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, Mizuho Corporate Bank and Mizuho Trust & Banking, are required toprovide customers with detailed disclosure regarding the financial products they offer and take other measures toprotect 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 supervisionof 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 SurveillanceCommission, 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 suchinspection may result in such registrants being subject to criminal penalty under the Financial Instruments andExchange Law.
Certain amendments to the Financial Instruments and Exchange Law and the Banking Law, which cameinto 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 toestablish systems for managing conflicts of interest in order to protect customers’ interests and expandedbusiness 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 complicatedproducts, can now be more freely marketed to customers. In response to this, the Law of Sales of Financial
Products (Kinyu Shouhin no Hanbai tou ni kansuru Houritsu) (Law 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 theperiod for rescission, unless the customers fall within the ambit of professional investors or express their intent tothe contrary; and holding financial service providers liable for damages caused by a failure to follow thoserequirements. 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 toendeavor 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 programthat complies with the Inspection Manual issued by the Financial Services Agency and related laws such as the
Financial Reconstruction Law (Kinyu Kinou no Saisei no tameno Kinkyu Sochi ni kansuru Houritsu) (Law
No. 132 of 1998, as amended). Financial institutions are required to analyze their assets, giving due considerationto accounting principles and other applicable rules and to classify their assets into four categories according toasset 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 accountthe 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 Manualissued 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.
36

Credit Limits
The Banking Law restricts the aggregate amount of loans to any single customer or customer group for the
purposes of avoiding excessive concentration of credit risks and promoting the fair and extensive utilization ofbank credit. The limits applicable to a bank holding company and bank with respect to their aggregate lending to
any single customer or customer group are established by a cabinet order and by the Banking Law. The current
limits are 25% of the total qualifying capital of the bank holding company or bank and its subsidiaries andaffiliates with respect to a single customer and 40% of the total qualifying capital of the bank holding company
or bank and its subsidiaries and affiliates with respect to a customer group.
Restriction on Shareholdings
The Law Concerning Restriction on Shareholdings by Banks (Ginkou tou no Kabushiki tou no Hoyu no
Seigen tou ni kansuru Houritsu) (Law No. 131 of 2001, as amended) requires Japanese banks (including bankholding 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 purchaseshares from banks and other financial institutions until September 30, 2006 pursuant to the Law Concerning
Restriction on Shareholdings by Banks. This law was further amended effective March 10, 2009 to allow the
Bank’s Shareholdings Purchase Corporation 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, 2012. The Bank’s Shareholdings Purchase Corporation purchased¥449.2 billion of shares during the period from March 12, 2009 through June 30, 2010. The Bank’s
Shareholdings Purchase Corporation will dispose of the purchased shares by March 31, 2022 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 thepurchased shares until March 31, 2012. The Bank of Japan will dispose of the purchased shares by September 30,
2017 by taking into consideration the effects on the stock market.
Capital Adequacy
The capital adequacy guidelines applicable to Japanese banks and bank holding companies withinternational 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 andstability of Japanese banks. Under the risk-based capital framework of these guidelines, balance sheet assets andoff-balance-sheet exposures are assessed according to broad categories of relative risk, based primarily on thecredit risk of the counterparty, country transfer risk and the risk regarding the category of transactions.
With regard to capital, these guidelines are in accordance with the standards of the Bank for International
Settlements for a target minimum standard capital adequacy ratio of 8% (at least half of which must consist ofCore Capital (Tier 1), a Core Capital ratio of 4%) on both a consolidated and non-consolidated basis for bankswith international operations, such as Mizuho Corporate Bank, or on a consolidated basis for bank holding
companies with international operations, such as Mizuho Financial Group.
Banks and bank holding companies are required to measure and apply capital charges with respect to theirmarket risks in addition to their credit risks. Market risk is defined as the risk of losses in on- and off-balance
sheet positions arising from movements in market prices such as the risks pertaining to interest rate related
instruments and equities.
37

Japanese banks with only domestic operations, such as Mizuho Bank, and bank holding companies thesubsidiaries of which operate only within Japan are subject to Japanese capital adequacy requirements that are
similar to those discussed above, except that those banks and holding companies are required to have a minimum
capital adequacy ratio of 4%, at least half of which must consist of Tier 1 capital and are not required to apply
capital charges to their market risks.
Under the capital adequacy guidelines, the maximum amount of net deferred tax assets under Japanese
GAAP that major Japanese banks, including bank holding companies, can record without diminishing the amountof Tier 1 capital for purposes of calculating capital adequacy is 20% of Tier 1 capital.
In June 2004, the Basel Committee on Banking Supervision announced amended rules with respect tominimum capital requirements, which include amended risk weight calculations that introduce an internal ratingsbased approach and the inclusion of operational risk in the calculations, as well as an emphasis on supervisory
review and market discipline through effective disclosure. The amendments adopt variable risk weights according to
the credit rating given to the obligor of the risk-weighted assets. The better the credit rating of an obligor is, thelower the risk weight applicable to the risk-weighted assets owed by it. Also, the new rules require financial
institutions to establish an internal risk management system, to make thorough disclosure of relevant informationand to set an appropriate reserve against the operational risk based upon fair evaluation thereof. The new Financial
Services Agency guidelines, which follow the amended rules, became effective on March 31, 2007, except for the
introduction of the advanced methodologies to calculate capital requirements for risks which took effect on
March 31, 2008. Under the new 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.
In December, 2009, the Basel Committee on Banking Supervision announced a package of proposals tostrengthen global capital and liquidity regulations with the goal of promoting a more resilient banking sector.
The Basel Committee on Banking Supervision’s proposals cover the following key areas:•

Raising the quality, consistency and transparency of the capital base;•Strengthening the risk coverage of the capital framework;•

Introducing a leverage ratio as a supplementary measure to the Basel II risk-based framework with aview to migrating to a minimum capital requirements treatment based on appropriate review andcalibration;•

Introducing a series of measures to promote the build-up of capital buffers in good times that can be
drawn upon in periods of stress; and•Introducing a global minimum liquidity standard for internationally active banks that includes a 30-day
liquidity coverage ratio requirement underpinned by a longer-term structural liquidity ratio.

The fully calibrated set of standards will be developed by the end of 2010 to be phased in as financial
conditions improve and the economic recovery is assured, with the aim of implementation by the end of 2012.
For further information of the proposals, see “Item 5. Operating and Financial Review and Prospects—Capital
Adequacy—Regulatory Capital Requirements.”
Protection of Personal Information
The Personal Information Protection Law (Kojin Jouhou no Hogo ni kansuru Houritsu) (Law No. 57 of2003, 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 totake necessary measures to comply with the law subjects us to criminal and/or administrative sanctions.
38

Prevention of Money Laundering
Under the Law Preventing Transfer of Profits Generated from Crime (Hanzai ni yoru Syueki no Iten Boushi
ni kansuru Houritsu) (Law 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.
Law Concerning Protection of Depositors from Illegal Withdrawals Made by Forged or Stolen Cards
The Law 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) (Law No. 94 of 2005, as amended),requires financial institutions to establish internal systems to prevent illegal withdrawals of deposits made 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.
Law Concerning Temporary Measures to Facilitate Financing for Small and Medium-Sized Enterprises (SMEs),
etc.
The Law Concerning Temporary Measures to Facilitate Financing for Small and Medium-Sized Enterprises(SMEs), etc. (Chuushoukigyousha tou ni taisuru Kinyuu no Enkatsuka wo Hakaru tameno Rinjisochi ni kansuru
Houritsu) (Law No. 96 of 2009) was enacted on November 30, 2009. The legislation requires financial
institutions, among other things, to make an effort to reduce their customers’ burden of loan repayments byemploying methods such as modifying the terms of loans at the request of eligible borrowers including SMEs
and individual home loan borrowers. The legislation also requires financial institutions to internally establish asystem to implement the requirements of the legislation and periodically make disclosure of and report to therelevant authority on the status of implementation. These measures are effective until March 2011.
United States
As a result of our operations in the United States, we are subject to extensive U.S. federal and statesupervision and regulation. We engage in U.S. banking activities through Mizuho Corporate Bank’s New York,
Chicago and Los Angeles branches and Houston and Atlanta representative offices. We also own two banks in
the United States, Mizuho Corporate Bank (USA) and Mizuho Corporate Bank of California, as well as
controlling interests in several other subsidiaries, including Mizuho Trust & Banking Co. (USA), which isengaged 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. The
enactment of the PATRIOT Act and other events have resulted in heightened scrutiny of compliance with the
Bank Secrecy Act and anti-money laundering rules by federal and state regulatory and law enforcement
authorities.
Mizuho Financial Group and Mizuho Corporate 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”). Under current Federal Reserve Board policy, these threecompanies are expected to act as a source of financial strength to Mizuho Corporate Bank (USA), Mizuho
Corporate Bank of California, and Mizuho Trust & Banking Co. (USA). The BHCA generally prohibits us fromacquiring, directly or indirectly, the ownership or control of more than 5% of any class of voting shares of any
39

company engaged in the United States in activities other than banking or activities that are financial in nature orincidental 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 under our merchant banking authority. In addition, U.S. regulatory approval is generally required for us toacquire more than 5% of any class of voting shares of a U.S. bank or savings association.
Mizuho Financial Group and Mizuho Corporate Bank became FHCs in December 2006. FHC status underthe 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 UnitedStates.
As a financial holding company, we are also subject to additional regulatory requirements. For example,
each of our U.S. insured depository institution subsidiaries with operations in the United States must be “wellcapitalized,” meaning a Tier 1 risk-based capital ratio of at least 6% and a total risk-based capital ratio of at least
10%. 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 Corporate Bank must also meet suchcapital standards as calculated under its home country standards (which must be comparable to the capitalrequired 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, anddivestiture or termination of certain business activities, or termination of our U.S. branches and agencies, may berequired 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 alsosupervised and regulated, by either a state banking authority or by the Office of the Comptroller of the Currency,
the 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 Corporate Bank is statelicensed. 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 Corporate Bank is subject to supervision, examination and regulation by
the New York State Banking Department as well as by the Federal Reserve Board. Except for the prohibition onsuch branch accepting retail deposits, a state-licensed branch generally has the same powers as a state-charteredbank in such state. New York State has an asset pledge requirement for branches equal to 1% of third party
liabilities with a cap of $400 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
Banking Department may require higher amounts for supervisory reasons. Each U.S. branch and representative
office of Mizuho Corporate Bank is subject to regulation and examination by the state banking authority of thestate in which it is located.
The deposits of Mizuho Corporate Bank (USA) are insured by the Federal Deposit Insurance Corporation(FDIC), and it is a state-chartered bank that is a member of the Federal Reserve System. As such, Mizuho
Corporate Bank (USA) is subject to regulation, supervision and examination by the Federal Reserve Board andthe New York State Banking Department, as well as to relevant FDIC regulation. The deposits of Mizuho
Corporate Bank of California are FDIC-insured, and it is a state-chartered bank that is not a member of theFederal Reserve System. As such, Mizuho Corporate Bank of California is subject to regulation, supervision and40examination by the FDIC and the California Department of Financial Institutions. The deposits of Mizuho
Trust & Banking Co. (USA) are also FDIC-insured, and it is a state-chartered bank and trust company that is nota member of the Federal Reserve System. As such, Mizuho Trust & Banking Co. (USA) is subject to regulation,
supervision and examination by the FDIC and the New York State Banking Department.
In the United States, U.S.-registered broker-dealers are regulated by the U.S. Securities and Exchange
Commission. 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 andsafekeeping 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 WallStreet Reform and Consumer Protection Act (the “Dodd Frank Act”), was signed into law by President Obamaon July 21, 2010. The Dodd-Frank Act will have far-reaching implications across the financial services
industry. 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 also creates a Bureau of Consumer Financial Protection with broad authority toregulate consumer financial products and services and imposes new regulation of the over-the-counter
derivatives market.
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 GroupWe provide a broad range of financial services in domestic and overseas markets through three Global

The Global Corporate Group provides wholesale and international banking and securities services,principally through Mizuho Corporate Bank and Mizuho Securities;•

The Global Retail Group provides retail and SME and middle-market corporation banking and securities
services in Japan, principally through Mizuho Bank and Mizuho Investors Securities; and•The Global Asset & Wealth Management Group provides trust and asset management services andprivate banking products and services, principally through Mizuho Trust & Banking, Trust & Custody

We also provide other services such as research services through Mizuho Research Institute, information

March 31, 2011 and make Orico an equity method affiliate of ours. See “Item 4.B. Information on the
Company—Business Overview.”

For a further discussion of our business and group organization, see “Item 4.B. Information on the
Company—Business Overview.”
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 interestearning 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 (suchas payables under repurchase agreements and payables under securities lending transactions) and debentures.
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 fees and commissions, investment gains (losses)—net, trading
account gains—net and foreign exchange gains (losses)—net.
Fees and commissions include the following:•

fees and commissions from deposits, debentures and lending business, which consist mostly of fees andcommissions related to our loan businesses, including fees related to the arrangement of syndicatedloans and other financing transactions such as arrangement fees related to management buy-outtransactions and fees related to deposits such as account transfer charges;•

fees and commissions from remittance business, including service charges for domestic andinternational funds transfers and collections;•

fees and commissions from securities-related business, including brokerage fees and commissions
related to securities underwriting and other securities-related activities;•

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 include primarily net gains 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.
45

Trading account gains—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 tocapture gains arising from short-term changes in market value. Trading account gains—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 andliabilities, as well as gains and losses related to changes in the fair value of foreign currency-denominatedavailable-for-sale securities that are elected for fair value treatment under ASC 825. For further information on
the fair value option, see note 29 to our consolidated financial statements included elsewhere in this annual
report.
Foreign exchange gains (losses)—net include mainly 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 include primarily salaries and employee benefits, general and administrative expenses,
occupancy expenses and fees 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 fees and commission expenses are fees and commission expenses for
remittance services, which include mainly commission expenses paid in connection with remittance transactions
and securities-related businesses, which include mainly 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.
After years of persistent weakness beginning in the 1990s, the Japanese economy had gradually improved over
the years by confronting structural issues such as deflationary pressures, excess capacity, excess employment andexcess leverage. However, since the fiscal year ended March 31, 2008, the global economy has weakened due
mainly to the effects of the dislocation in the global financial markets. The global economy continued to worsen
in the fiscal year ended March 31, 2009, and financial results in the financial and industrial sectors deteriorated
significantly.
In the fiscal year ended March 31, 2010, the actions taken to stabilize the financial system and stimulate theeconomy by major countries in cooperation with each other in response to the financial crisis have been effective,
and the global economy has emerged from its worst and is maintaining a gradual recovery. As for the Japanese
economy, it has entered a mild deflationary state with a severe employment and income environment continuing,and prospects of a self-sustaining recovery in domestic private-sector demand remain weak. However, exports
and personal consumption, especially of durable goods, continue to strengthen, reflecting improvements in theforeign economic environment and the effectiveness of economic stimulus packages, and the economy is
beginning to recover, with a return to positive real gross domestic product growth from the second quarter of46

calendar year 2009 compared to the preceding quarter. Although the annualized real gross domestic productincreased by 5.0% in the first quarter of calendar year 2010, compared to the preceding quarter (seasonallyadjusted), in a situation where causes for concern exist, such as the effects of the cessation of economic stimulus
packages, worsening employment and the aggravation of the financial condition of certain nations in Europe andother areas, it remains uncertain whether the global economy will be capable of maintaining growth going
forward as the risk that the global economy will continue to stagnate still remains. Key indicators of economic
conditions in recent periods include the following:•

Japan’s real gross domestic product on a year-on-year basis continued to increase by 2.3%, 2.3%, 1.8%
in the fiscal years ended March 31, 2006, 2007 and 2008, respectively, but decreased by 3.7% and 2.0%
in the fiscal years ended March 31, 2009 and 2010, respectively. After showing a gradual reduction in
the rate of decline in each quarter of calendar 2009, Japan’s real gross domestic product on a quarterly
basis, compared to the corresponding period of the previous year, increased by 4.6% in the first quarterof calendar 2010. The Japanese Government stated in its monthly economic reports for January andFebruary 2010 that although the economy has been picking up, it is short of autonomous factors andremains in a difficult situation such as a high unemployment rate. From March through May 2010, thereports began to reflect improvement of the economic situation and stated that, although the economy
has been picking up steadily, it is only weakly self-sustaining and remains in a difficult situation such asa high unemployment rate. In the June 2010 report, it added that a foundation for a self-sustaining
recovery is being laid, although the difficult situation such as the high unemployment rate remains.
Japan’s core nationwide consumer price index increased by 0.1%, 0.1%, 0.3% and 1.2% in the fiscal
years ended March 31, 2006, 2007, 2008 and 2009, respectively but decreased by 1.6% in the fiscal year
ended March 31, 2010. The Japanese Government stated in its monthly economic reports from
November 2009 onwards that the Japanese economy is in a mild deflationary phase. The following chartshows 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 2005 through the first quarter of 2010:(%)

The Bank of Japan, following its announcement on March 9, 2006 to end its “quantitative easing”
monetary policy that it had maintained since March 2001, announced on July 14, 2006 and on
February 21, 2007 that it raised its target for the uncollateralized overnight call rate from 0% to 0.25%
and from 0.25% to 0.5%, respectively, but it lowered its target for the uncollateralized overnight callrate from 0.5% to 0.3% in October 2008 and to 0.1% in December 2008. In December 2009, the Bank ofJapan announced that it would provide approximately ¥10 trillion in short-term funds to commercial
banks at a low fixed rate in order to boost liquidity and recover stability in the financial markets and that
it would increase the amount to approximately ¥20 trillion in March 2010. In addition, in June 2010, theBank of Japan announced that it would introduce a fund-provisioning measure under which it would
provide long-term funds to commercial banks at a low fixed rate in order to support the strengthening of
the foundations for economic growth. The measure is expected to be implemented beginning around theend of August 2010. The following charts show movements in long-term rates from January 2007
through June 2010, represented by the yield on newly issued 10-year Japanese government bonds, andin short-term interest rates from January 2007 through June 2010, represented by the three-month Tokyo

Capital Improvements
All yen figures in this subsection are truncated. Accordingly, the total of each column of figures may not be
equal to the total of the individual items.
Our basic policy is to pursue “disciplined capital management,” by which we pursue an optimal balance
between “strengthening of stable capital base” and “steady returns to shareholders” in accordance with changes
in the business environment, our financial condition and other factors.
Shift of Priority
While our basic policy remains unchanged, we have been putting more priority on strengthening our stable
capital base from the second half of the fiscal year ended March 31, 2009, having recognized the importance ofcapital during the financial dislocation and global economic downturn. Measures we took for responding to theabove priority include the following:•

We suspended repurchases and cancellation of shares of our common stock since the second half of the
fiscal year ended March 31, 2009.

•

We paid cash dividends for the fiscal year ended March 31, 2010 of ¥8 per share of common stock, a
year-on-year decrease of ¥2 per share.

•

In June, August and September 2009, we issued ¥139.5 billion, ¥72.5 billion and ¥25.0 billion,
respectively, of non-dilutive preferred securities through our overseas special purpose companies toenhance our Tier 1 capital and improve the flexibility of our future capital strategy.

•

In July and August 2009, we issued an aggregate of ¥529.2 billion in common stock through a global
offering to strengthen our “prime capital,” as such term is defined in “—Capital Adequacy—Prime
Capital,” in order to build a solid and sufficient capital buffer.

Announcement of Proposals Regarding New Bank Capital Regulations
In December 2009, the Basel Committee announced a package of proposals, covering key areas such as
raising the quality of the capital base, establishing a countercyclical capital framework and introducing a global
minimum liquidity standard, with the goal of promoting a more resilient banking sector. The proposals are
subject to further discussion of details. The proposal regarding raising the quality of the capital base aims toensure that the banking system is in a better position to absorb losses. The specific levels of minimum regulatory
capital requirement including that for the “Common Equity” component of Tier 1 capital, together with the fully
calibrated set of standards, are currently scheduled to be determined by the end of calendar year 2010 after acomprehensive impact assessment, with the aim of implementation by the end of 2012 as financial conditions
improve and the economic recovery is assured. The Basel Committee also stated that it will consider appropriate
phase-in measures and grandfathering arrangements for a sufficiently long period to ensure a smooth transition to
the new standards.
While closely monitoring the ongoing global discussions with respect to capital, we took the following
measures to further strengthen our capital base:•

In April 2010, we redeemed all of the $1.5 billion of perpetual subordinated bonds.

52

•In May 2010, we announced our plan to reduce dividends on our common stock for the fiscal year
ending March 31, 2011 by ¥2 per share compared to the previous fiscal year to ¥6 per share. The
foregoing statement constitutes a forward-looking statement and is subject to risks, uncertainties andassumptions. See “Forward-looking Statements” and “Item 3.D. Key Information—Risk Factors.”•

In addition to the above measures, in July 2010, we issued an aggregate of ¥751.62 billion in common
stock (including the shares to be issued pursuant to the exercise of the over-allotment option in Japan)
through a global offering to establish capital base as a cornerstone for our sustainable growth for the
future, in anticipation of the revision of capital regulations, and thereby ensuring capital flexibility for
us to expand our business areas with high growth potential and to promote customer-related businesses
further.

We will continue to pursue optimal balance between “strengthening of stable capital base” and “steadyreturns to shareholders.” Following this basic policy, we will take various measures in anticipation of the revisionof capital regulations. See “Item 4.B. Information on the Company—Business Overview—The Transformation
Program (Aiming at Sustainable Growth).”Business Trends
Based on our current operating environment and management focus, we believe that the trends that are mostsignificant to our current and future results of operations include the following:
Loans and Deposits
Loan volume
Our total loan balance decreased on a year-on-year basis in the fiscal year ended March 31, 2010 due mainly
to decreases in loans to Deposit Insurance Corporation of Japan, the Japanese government, overseas borrowers
and large Japanese corporations despite our continuing efforts to meet the financing needs of domestic
borrowers.
Margins between loans and deposits
The Bank of Japan announced on July 14, 2006 and on February 21, 2007 that it raised its target for theuncollateralized overnight call rate from 0% to 0.25% and from 0.25% to 0.5%, respectively. Reflecting theseraises, the average yield on domestic loans increased from 1.54% in the fiscal year ended March 31, 2007 to
1.77% in the fiscal year ended March 31, 2008, and the average rate on domestic interest-bearing deposits
increased from 0.38% to 0.52%. The increase of 0.23% in average yield on domestic loans in the fiscal year
ended March 31, 2008 compared to the previous fiscal year was larger than the increase of 0.14% in the averagerate on domestic interest-bearing deposits over the same period, resulting in a widening of the difference between
such average yield and average rate. In response to the weakening economic environment, the Bank of Japanannounced a reduction of its target for the uncollateralized overnight call rate from 0.5% to 0.3% in October
2008 and to 0.1% in December 2008. Reflecting these reductions, the average yield on domestic loans decreased
from 1.72% in the fiscal year ended March 31, 2009 to 1.51% in the fiscal year ended March 31, 2010, and theaverage rate on domestic interest-bearing deposits decreased from 0.43% to 0.21%. In the fiscal year ended
March 31, 2010, the difference between the decrease of 0.21% in the average yield on domestic loans and thedecrease of 0.22% in the average rate on domestic interest-bearing deposits was not significant.
Provision (credit) for loan losses
Provision for loan losses decreased by ¥345 billion from the previous fiscal year to ¥222 billion for the
fiscal year ended March 31, 2010. The decrease in provision for loan losses was due mainly to an improvementin economic conditions and our efforts for appropriate credit management. 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 be53

affected by the domestic and global economic environment and other factors, and changes in the value ofcollateral on our loans. If worldwide demand for Japanese products and services declines and if weakness in theJapanese and global economy worsens or if another financial crisis develops, there can be no assurance that theamount of provision for loan losses will not increase significantly in future periods due to further declines in thecredit quality of our customers both in and outside of Japan.
Fees and Commissions
Fees and commissions from corporate and retail customers have been significantly affected by the domestic
and global economic environment. Until the fiscal year ended March 31, 2006, we experienced a period ofsignificant increases in fees and commissions due to an expansion in various fee businesses that we offer to our
corporate customers, such as fees from syndicated loans, other forms of financing arrangements and various
advisory services, as demand for such products and services grew among Japanese corporations. Fees andcommissions from retail customers had also increased due to growth in sales commissions related to various
investment products as Japanese individuals increased the proportion of investments other than deposits within
their total financial assets as interest rates on deposits maintained historically low levels. Despite our expectation
at the time for continued growth in fees and commissions, a weak economic environment and turmoil in the
global financial market, as well as increased competition within the domestic financial services industry, drove adecline in fees and commissions in the fiscal year ended March 31, 2008, and the decline accelerated in the fiscal
year ended March 31, 2009. Fees and commissions earned from businesses involving corporate customers
decreased in the fiscal year ended March 31, 2009 due to increased competition and the dislocation in the global
financial markets which negatively impacted areas such as overseas leveraged buyout and other financings.
Under unstable market conditions, sales of investment products to retail customers were negatively affected due
mainly to the growing risk aversion of individuals. Although this trend may continue while the current global anddomestic economic uncertainty continues, we do not believe that the general trend in recent years of Japaneseindividuals to shift their financial assets from savings to investments was only short term and instead believe thatthe trend will return over the long term.
Fees and commissions income increased by ¥25 billion from the previous fiscal year to ¥586 billion in thefiscal year ended March 31, 2010 due mainly to an increase at Mizuho Securities, while those of our principal
banking subsidiaries continued to decrease. However, the rate of decrease of our principal banking subsidiaries’
fees and commissions has slowed as the Japanese economy has begun to recover.
Debt and Equity Securities Portfolio
The amount of our funding through deposits and debentures significantly exceeds our total loans. As aresult, we allocate a significant portion of such excess among investments in debt securities, including Japanese
government bonds and credit and alternative investments, which we promote to diversify our risks and to expand
our income sources, and we also hold investments in equity securities consisting mainly of common stock ofJapanese listed company customers.
The fair value of available-for-sale marketable equity securities within our investments was ¥3,284 billion,or ¥2,007 billion based on cost, as of March 31, 2010. 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 andlosses related to changes in the fair value of available-for-sale marketable equity securities are reflected inaccumulated 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. Although we expect the size of our portfolioof marketable equity securities to continue to be significant, we are reducing our holdings of marketable equity
securities and have achieved our former medium-term target to lower the acquisition cost of marketable equity
securities to 50% of our Tier 1 capital as of March 31, 2010 (the ratio of the acquisition cost to Tier 1 capital asof March 31, 2010 was 49%). We will continue to make efforts to lower the acquisition cost of marketable equity
securities. See “Item 4.B. Information on the Company—Business Overview—The Transformation Program(Aiming at Sustainable Growth).”54

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, while decreases in long-term interest
rates generally lead to an increase in fair value of the portfolio. As of March 31, 2010, we had a total of ¥34,517
billion of available-for-sale debt securities within our investments, of which ¥28,229 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 toincome as an impairment loss. We had ¥24,685 billion and ¥34,517 billion of available-for-sale debt securities asof March 31, 2009 and 2010, respectively, and unrealized losses of ¥26 billion and unrealized gains of ¥9 billion
were reflected in accumulated other comprehensive income, net of tax as of such dates, respectively. In the fiscal
year ended March 31, 2010, we incurred investment losses related to bonds of ¥2 billion compared to losses of¥178 billion in the fiscal year ended March 31, 2009. The decrease was due mainly to the absence of impairment
losses on Japanese government bonds as we adopted ASC 320 which amends the other-than-temporary
impairment model for debt securities.
Trading Account Gains—Net
Trading account gains—net increased by ¥300 billion from the previous fiscal year to ¥422 billion in thefiscal year ended March 31, 2010. The increase was due mainly to the gains earned by consolidated VIEs, suchas stock investment trusts, as a result of a positive change in market conditions, an increase in gains related tochanges in the fair value of derivative financial instruments used to hedge market risks, mainly interest rate risk,that are not eligible for hedge accounting under U.S. GAAP and an increase in gains related to changes in the fairvalue of foreign currency denominated available-for-sale securities for which the fair value option was elected.
Costs and Expenses
In the fiscal year ended March 31, 2010, salaries and employee benefits increased by ¥96 billion from theprevious fiscal year to ¥592 billion due mainly to the effect of increased employee retirement benefit expenses asa result of a decline in expected return on plan assets, which reflects various aspects of long-term prospects forthe economy, historical performance of investments of plan assets and the market environment, including stock
market conditions, at the beginning of the fiscal period, and the amortization of net actuarial loss, whichprimarily reflects past declines in the value of plan assets. Occupancy expenses and general and administrative
expenses decreased by ¥6 billion and ¥2 billion, respectively, due mainly to our efforts to enhance our cost
efficiency through detailed reviews. Although expenses related to employee retirement benefits reflect the market
environment including stock markets conditions, we plan to continue our efforts to reduce general andadministrative expenses and occupancy expenses through detailed reviews for the entire group. See“Item 4.B. Information on the Company—Business Overview—The Transformation Program (Aiming at
Sustainable Growth).”Impact of the Dislocation in the Global Financial Markets
All figures in this subsection are approximate amounts used for risk monitoring purposes that aremanagerial accounting compilations of Japanese GAAP-based figures.
The global financial market dislocation, which had caused not only significant liquidity problems anddeclines in value with respect to securitization products such as residential mortgage backed securities (RMBS)
and collateralized debt obligations (CDOs) backed by RMBS but also adverse impacts on various markets, had
thereby adversely affected our financial condition and results of operations in recent years. However, in the fiscal
year ended March 31, 2010, due primarily to our efforts to reduce the balances of our securitization products
through sales and other measures and to reinforce our risk management platform for securitization products andthe gradual market recovery, the negative impact of the dislocation became more limited, and the losses incurred
decreased significantly compared to the previous fiscal year. This subsection sets forth information relating tosuch impact.

Note:
(1) Our other principal securities subsidiary, Mizuho Investors Securities, held only a negligible amount of
securitization products as of March 31, 2009 and 2010, and its related gains (losses) were also negligible.
The figures do not include reserves for counterparty risks associated with the amount to be claimed atsettlement of the CDS related to securitization products described in the table titled “Credit default swaps
related to foreign currency-denominated securitization products held by Mizuho Securities (including its
overseas subsidiaries)” on page 58.
Securitization Products
We continue to hold a significant amount of securitization products. The balance (fair value) (banking
account) of securitization products held by our principal banking subsidiaries (including their overseas
subsidiaries, but excluding subsidiaries of Mizuho Securities) was approximately ¥2,469 billion, of whichapproximately ¥487 billion was foreign currency-denominated as of March 31, 2010. Similarly, the net balance(fair value) (trading account) held by Mizuho Securities (including its overseas subsidiaries) was approximately¥149 billion, of which approximately ¥21 billion was foreign currency-denominated as of March 31, 2010.

Notes:(1) Except for the securitization products which were the reference assets of our securitization schemes for transferring
credit risk to third parties (hedged portion), a reserve for possible losses on investments has been provided against
unrealized losses on securitization products related to the discontinuation of business regarding credit investments
primarily in Europe, which had been made as an alternative to loans. The balance of the reserve was approximately ¥15billion as of March 31, 2010. Since securities were recognized at fair value on the consolidated balance sheet, thebalances as of March 31, 2010 were those after being offset by the amount of reserve for possible losses on investments.
(2) With respect to the vast majority of credit investments in securitization products made as an alternative to loans by theEuropean, North American and other offices, we have been applying reasonably calculated prices based on thereasonable estimates of our management as fair value since the fiscal year ended March 31, 2009.
(3) The approximate proportions of balances (fair value) of the securitization products, as of March 31, 2010, which were
the reference assets of our securitization schemes (with CDS and other means) for transferring credit risk to third parties
until maturity. In some of the securitization schemes, a portion of credit risk of the reference assets remained with us
through our retaining a small first loss position and a portion of senior tranches.
<Reference> Status of CDS counterparties (notional amount basis; ratings were based on the lowest external ratings as ofMarch 31, 2010): Financial services subsidiary (A-rating) of a multi-line insurance company: approximately ¥144
billion; Government-affiliated financial institution (AA-rating): approximately ¥91 billion.
(4) All of them were securitization products backed by original assets (non-securitized assets).

57(5) Excluding U.S. government-owned corporation bonds and government-sponsored enterprise bonds. As of March 31,
2010, U.S. government-owned corporation bonds and government-sponsored enterprise bonds held by us were as
follows:
Principal banking subsidiaries (including their overseas subsidiaries, but excluding subsidiaries of Mizuho Securities):
U.S. government-owned corporation (Ginnie Mae) bonds and government-sponsored enterprise (Fannie Mae and FreddieMac) bonds were approximately ¥583 billion (fair value), of which almost all consisted of RMBS guaranteed by Ginnie
Mae, with approximately ¥9 billion of unrealized gains. Mizuho Securities (including its overseas subsidiaries):
approximately ¥40 billion (fair value) of RMBS issued or guaranteed by Ginnie Mae or government-sponsored enterprise(Fannie Mae and Freddie Mac) and approximately ¥171 billion (fair value) of corporate bonds issued by Fannie Mae andFreddie Mac were held for the purpose of, among other things, market-making activities in the U.S.

Loans Held for Sale for which Reserve for Possible Losses on Sales of Loans was Recorded (the Principal
Banking Subsidiaries (including their Overseas Subsidiaries, but excluding Subsidiaries of Mizuho Securities))
As of March 31, 2010, we had a total of approximately ¥61 billion in loans held for sale. We recorded
approximately ¥15 billion of reserve for possible losses on sales of loans against these loans held for sale as ofMarch 31, 2010 at a reserve ratio of approximately 25%. These figures exclude those related to intensive control
obligors classification or below. The reserve ratio would be approximately 25%, if including the balances ofloans held for sale to such obligors and the amounts of both reserves for possible losses on loans and reserve forcontingencies in relation to the relevant balances.
The total balance of leveraged loans, primarily including LBO financing and MBO financing, includingloans held for sale and loans held within our loan portfolio, was approximately ¥1.0 trillion of which59approximately ¥0.05 trillion was included in loans held for sale as of March 31, 2010. The balances include
commitments that had not been drawn but for which documentation had been concluded.
Overseas Asset-backed Commercial Paper Programs (the Principal Banking Subsidiaries (including theirOverseas Subsidiaries, but excluding Subsidiaries of Mizuho Securities))
As of March 31, 2010, the balance of the total assets acquired by overseas asset-backed commercial paper
conduits was approximately ¥59 billion, which included approximately ¥32 billion of securitization products
backed by credit card receivables and account receivables. Of the total balance of ¥59 billion, credit card
receivables constituted 31%, account receivable constituted 29%, loans against auto dealers constituted 25% andothers constituted 15%.
Loans Guaranteed by U.S. Monoline Insurers (the Principal Banking Subsidiaries (including their Overseas
Subsidiaries, but excluding Subsidiaries of Mizuho Securities))
As of March 31, 2010, approximately ¥16 billion of loan commitments to overseas infrastructure projects(of which approximately ¥8 billion was drawn) was guaranteed by U.S. monoline insurers.
Outstanding Loan Balances to U.S. Mortgage Lenders (the Principal Banking Subsidiaries (including theirOverseas Subsidiaries, but excluding Subsidiaries of Mizuho Securities))
As of March 31, 2010, we had a total of approximately ¥10 billion in outstanding loans to U.S. mortgage
lenders.
As shown in this subsection, we continue to hold a significant amount of assets that are exposed to the risk
of further declines in value or that may otherwise lead to further losses. While we will endeavor to continue
reducing the amount of foreign currency-denominated securitization products through sales or other measures,
our exposure to assets that are subject to such risks may increase in the future depending on market conditions
and other factors.
Our Special Purpose Entities
Our use of special purpose entities relates mainly to variable interest entities, or VIEs, and qualifying special
purpose entities, or QSPEs. The following sets forth information regarding our VIEs and QSPEs.
Variable Interest Entities (VIEs)
Our VIEs are distinguished between those that are consolidated for purposes of our consolidated financial
statements and those that are not. VIEs are consolidated if we are deemed to be the primary beneficiary of those
VIEs. With respect to certain unconsolidated VIEs, we determined that, while we were not the primary
beneficiary, they were “significant or sponsored unconsolidated variable interest entities” due to our significant
variable interests. In the normal course of business, we are involved with VIEs primarily through the following
types of transactions:•asset-backed commercial paper/loan programs;•

asset-backed securitizations;•investments in securitization products;•

investment funds; and•trust arrangements and other.

Note:(1) Maximum exposure to loss is the contractual or notional amounts of liquidity facilities and otheroff-balance-sheet credit related support or principal amount of financing or investments, and is notindicative of the ongoing exposure which is managed within our risk management framework.
Asset-backed commercial paper/loan programs in the above table consist of multi-seller programs that wemanage, which provide our clients with off-balance-sheet and/or cost-effective financing. Asset-backed
securitizations in the above table consist of non-multi-seller programs that we arrange, which include various
types of structured financings to meet clients’ various off-balance-sheet financing needs (referred to as singleseller programs in this subsection) and CDOs, CLOs or other repackaged instruments that are issued by VIEs tomeet clients’ or investors’ financial needs.
We generally provide liquidity and credit support facilities and other financing to VIEs related to the multiand single-seller programs, and as a result, these VIEs are generally treated as consolidated VIEs.
See note 27 in our consolidated financial statements included elsewhere in this annual report for further
descriptions regarding the above transaction types including those other than the two described above.
Asset-backed commercial paper/loan programs
VIEs categorized under asset-backed commercial paper/loan programs consist of conduits for multi-seller
programs. These VIEs purchase receivables from participating clients and other financial assets to meet
off-balance-sheet or liquidity needs. The following tables show certain information related to such multi-seller
asset-backed commercial paper/loan programs and their acquired assets as of March 31, 2010. All figures in thetables below and in the accompanying footnotes are approximate amounts based on a managerial accounting

Note:
(1) Credit ratings are based on internal credit ratings.
Asset-backed securitizations
VIEs categorized under asset-backed securitizations include several single-seller programs used for the
purpose of off-balance-sheet financing for our corporate customers, to which we provide liquidity and credit
support facilities and other financing and are thus generally consolidated. Typically, VIEs related to single-seller
programs purchase corporate claims such as account receivables from our corporate customers and provide
factoring services. Those claims are generally generated in the normal course of the on-going businesses of ourJapanese corporate customers in Japan, and thus we view the risks related to our providing liquidity and credit
support facilities and other financing to be relatively limited under current circumstances. The aggregate amountof assets of such single-seller VIEs was ¥81 billion as of March 31, 2010.
VIEs categorized under asset-backed securitizations also include VIEs that issue CDOs, CLOs or otherrepackaged instruments that we arrange. The aggregate amounts of assets held by VIEs that issue CDOs
categorized as consolidated VIEs and significant or sponsored unconsolidated VIEs were ¥12 billion and¥77 billion, respectively. Our maximum exposure to loss with respect to such significant or sponsoredunconsolidated VIEs was negligible.
Losses relating to VIEs that issue such CDOs, CLOs or other repackaged instruments due to the dislocationin the global financial markets in the fiscal year ended March 31, 2010 are generally reflected in our financial
statements either through consolidation in the case of consolidated VIEs or through a decline in the value of ourinterest in VIEs in the case of unconsolidated VIEs.
Qualifying Special Purpose Entities (QSPEs)
QSPEs are passive entities designed to purchase assets and pass through the cash flows from those assets tothe investors and, subject to specified conditions, are generally exempt from consolidation pursuant to ASC 810.
The total assets of our QSPEs were ¥308 billion as of March 31, 2010. The acquired assets of such QSPEs wereprimarily residential mortgage loans in Japan.

Critical Accounting Estimates
Note 1 to our consolidated financial statements included elsewhere in this annual report contains a summaryof 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 criticalaccounting 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 toperiod. 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 ourlending 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 toextend 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 expected cash flows discounted at theloans’ initial effective interest rates, or as a practical expedient, using the observable market prices 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. Management
identifies impaired loans through the credit quality review process, in which the debtor’s ability toservice its debt is assessed. The difference between our evaluation of the value of the impaired loan andits 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 formulabased 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 andother non-homogenous loans which 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 fromthird-party sources. The estimation of the formula allowance is back-tested on a periodic basis bycomparing 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 notdeemed 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 using the same categories and evaluation methods as loans.
We similarly assess probable loss amounts for loan commitments, taking into account the probability ofdrawdowns.
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,64

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 affectour financial condition and results of operations. For example, if our current judgment with respect to expected
future cash flows differ from actual results, including as a result of an unexpected adverse change in theeconomic environment in Japan or a sudden and unanticipated failure of a large borrower, or if the value ofcollateral declines, we may need to increase the allowances with additional charges to earnings.
Valuation of Financial Instruments
ASC 820, “Fair Value Measurements and Disclosures” (“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 andliabilities include debt securities with quoted prices that are traded less frequently than exchangetraded instruments. If no quoted market price is available, the fair values of debt securities and overthe-counter derivative contracts in this category are determined using a pricing model with inputs thatare 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 thefair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose
value is 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 offair 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 inconnection therewith, see note 29 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 amountsof 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 and future reversals of existing taxable temporary
differences. 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. For example, variances in future projected operating performance or tax law
changes that impact our tax planning strategies could result in a change in the valuation allowance. If we are notable 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 such determination is made, and this could materially andadversely affect our financial condition and results of operations.
65

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 andaccrued liabilities are computed based on a number of actuarial assumptions, including mortality, withdrawals,
discount rates, expected long-term rates of return on our plan assets and rates of increase in future compensationlevels.
Actual results that differ from the assumptions are accumulated and amortized over future periods andtherefore generally affect future pension expenses. While management believes that the assumptions used areappropriate, 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 governmental andcorporate bonds that received a rating of AA(Aa) or higher from rating agencies. The durations of such bonds
closely match that of the pension benefit obligation. Assumed discount rates were reevaluated at eachmeasurement 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 benefits, see note 22 to the consolidated financial statements
included elsewhere in this annual report.

Executive Summary
Fiscal Year Ended March 31, 2010 Compared to Fiscal Year Ended March 31, 2009
Net interest income decreased by ¥178 billion, or 13.9%, from the previous fiscal year to ¥1,104 billion in
the fiscal year ended March 31, 2010 due to a decrease in net foreign interest and dividend income of ¥186
billion. The decrease was due mainly to a decrease of ¥521 billion in foreign interest and dividend income offset
in part by a decrease of ¥335 billion in foreign interest expense. The decrease in foreign interest and dividend
income was due mainly to decreases in interest from foreign loans and income from foreign call loans and funds
sold, and receivables under resale agreements and securities borrowing transactions, both of which reflect generaldeclines in U.S. dollar and euro interest rate levels. The decrease in foreign interest expense was due mainly todecreases in interest expense on foreign short-term borrowings and foreign interest-bearing deposits. These
decreases were due mainly to the decrease in average interest rates, reflecting general declines in U.S. dollar andeuro interest rate levels. Domestic interest and dividend income and domestic interest expense both declined
significantly due to declines in yen interest rate levels, but net domestic interest and dividend income showed aslight increase due to the amounts of decline being similar.
Noninterest income increased by ¥879 billion from the previous fiscal year to ¥1,331 billion in the fiscal
year ended March 31, 2010. The increase was due mainly to gains in investment gains (losses)—net of ¥67
billion in the fiscal year ended March 31, 2010, compared to losses in investment gains (losses)—net of ¥462
billion in the fiscal year ended March 31, 2009 and an increase in trading account gains—net of ¥300 billion. The
increase in investment gains (losses)—net was due mainly to investment gains related to bonds and investment
gains related to equity securities. Investment gains related to bonds in the fiscal year ended March 31, 2010 weredue mainly to an absence of impairment losses on Japanese government bonds as we adopted ASC 320 whichamends the other-than-temporary impairment model for debt securities. Investment gains related to equity
securities were due mainly to a decrease in impairment losses on equity securities as a result of a recovery in thestock markets. The increase in trading account gains—net was due mainly to the gains earned by consolidated
VIEs, such as stock investment trusts, as a result of a positive change in market conditions, an increase in gains
related to changes in the fair value of derivative financial instruments used to hedge market risks, mainly interest
rate risk, that are not eligible for hedge accounting under U.S. GAAP and 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 waselected.
Noninterest expenses in the fiscal year ended March 31, 2010 was almost the same level compared to theprevious fiscal year. Salaries and employee benefits increased by ¥96 billion in the fiscal year ended March 31,
2010, offset in part by provision (credit) for losses on off-balance-sheet instruments being a credit of ¥24 billion
in the fiscal year ended March 31, 2010 compared to a provision of ¥84 billion in the previous fiscal year. The
increase in salaries and employee benefits were due mainly to the effect of increased employee retirement benefit
expenses as a result of a decline 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 period, and the amortization of net actuarial loss,
which primarily reflects past declines in the value of plan assets. The decrease was due mainly to a decrease inallowance for losses on off-balance-sheet transactions primarily as a result of the decrease in the balance ofguarantees to overseas obligors.
As a result of the foregoing, income (loss) before income tax expense (benefit) was income of ¥687 billion
in the fiscal year ended March 31, 2010 compared to a loss of ¥358 billion in the fiscal year ended March 31,
2009. We had an income tax benefit of ¥360 billion in the fiscal year ended March 31, 2010 compared to an
income tax expense of ¥762 billion in the fiscal year ended March 31, 2009. The benefit was the result of anincrease in deferred tax assets.
Net income (loss) was income of ¥1,047 billion in the fiscal year ended March 31, 2010 compared to a lossof ¥1,120 billion in the fiscal year ended March 31, 2009. Net income (loss) attributable to noncontrolling67

interests was income of ¥47 billion in the fiscal year ended March 31, 2010 compared to a loss of ¥62 billion in
the fiscal year ended March 31, 2009. As a result, net income (loss) attributable to MHFG shareholders wasincome of ¥1,000 billion in the fiscal year ended March 31, 2010 compared to a loss of ¥1,058 billion in thefiscal year ended March 31, 2009.
Fiscal Year Ended March 31, 2009 Compared to Fiscal Year Ended March 31, 2008
Net interest income increased by ¥84 billion, or 7.0%, from the previous fiscal year to ¥1,282 billion in thefiscal year ended March 31, 2009 due to an increase in net foreign interest and dividend income of ¥47 billion
and an increase in net domestic interest and dividend income of ¥37 billion. The increase in net foreign interestand dividend income was due mainly to decreases in interest expense on foreign short-term borrowings andforeign interest-bearing deposits as a result of decrease in the average interest rates, offset in part by a decrease ininterest and dividend income from foreign call loans and funds sold, and receivables under resale agreements andsecurities borrowing transactions as a result of decrease in the average yields, both of which reflect generaldeclines in U.S. dollar and euro interest rate levels. The increase in net domestic interest and dividend income
was due mainly to a decrease in interest expense on domestic interest-bearing deposits, reflecting a decrease in
the average interest rate as a result of a decline in yen interest rate levels, offset in part by a decrease in interestand dividend income from domestic investments and a decrease in interest income from interest-bearing deposits
in other banks. The decrease in interest and dividend income from domestic investments was due to a decrease in
the average balance of domestic investments due mainly to the decrease in the balance of equity securities
reflecting declines in domestic stock prices and the balance of debt securities as a result of the turmoil in thefinancial markets, and the decrease in interest income from interest-bearing deposits in other banks was due
mainly to a decrease in average yields as a result of a decline in yen interest rate levels. We had a provision forloan losses of ¥567 billion compared to a credit of ¥58 billion in the previous fiscal year due mainly to declines
in the financial condition of domestic SMEs and middle-market corporations, the effect of the collapse of
Lehman Brothers on our exposures to related entities and the weakening credit status of overseas loans reflecting
the global economic downturn, as well as increased estimated loss rates related to normal obligors.
Noninterest income decreased by ¥643 billion, or 58.7%, from the previous fiscal year to ¥452 billion in thefiscal year ended March 31, 2009 due mainly to a decrease in foreign exchange gains—net, an increase ininvestment losses—net and a decrease in fees and commissions. The decrease in foreign exchange gains—net
was due mainly to translation gains with respect to foreign currency-denominated liabilities in the fiscal year
ended March 31, 2008 that were funded and incurred to offset foreign exchange risk related to foreign
currency-denominated available-for-sale securities. The increase in investment losses—net was due mainly toinvestment losses related to equity securities in the fiscal year ended March 31, 2009, compared to investment
gains related to equity securities in the previous fiscal year, as a result of an increase in impairment losses on anda decrease in gains on sales of equity securities reflecting declines in domestic and overseas stock markets. The
decrease in fees and commissions was due mainly to a decrease in fees for other customer services and adecrease in fees and commissions from securities-related business. The decrease in fees for other customer
services was due mainly to a decrease in trust business-related fees other than those included in trust fees such as
brokerage fees related to real estate transactions and other fees and commissions such as sales agency fees related
to insurance products including individual annuities. The decrease in fees and commissions from securitiesrelated business was due mainly to decreases in underwriting commissions related to private offerings of debt
securities and sales commissions related to investment trusts which were negatively impacted by adverse market
conditions, including declines in domestic stock markets.
Noninterest expenses increased by ¥21billion, or 1.4%, from the previous fiscal year to ¥1,525 billion in thefiscal year ended March 31, 2009 due mainly to an increase in the provision for losses on off-balance-sheet
instruments and an increase in salaries and employee benefits, offset in part by a decrease in impairment of
goodwill and a decrease in other noninterest expenses. The increase in provision for losses on off-balance-sheet
instruments was due mainly to an increase in allowance for losses on off-balance-sheet transactions primarily asa result of downgrades in credit ratings of some obligors reflecting declines in their financial condition. The
68

increase in salaries and employee benefits was due mainly to the effect of increased employee retirement benefit
expenses as a result of a decline in expected return on plan assets and the amortization of net actuarial loss in thefiscal year ended March 31, 2009 compared to the amortization of net actuarial gain in the previous fiscal year.
The decrease in impairment of goodwill was due to impairment of goodwill incurred in the fiscal year ended
March 31, 2008 as a result of the carrying amount of Mizuho Investors Securities and Mizuho Securities
exceeding their fair value. The decrease in other noninterest expenses was due mainly to the decrease invaluation losses related to loans held for sale mainly in connection with overseas leveraged buyout financings.
As a result of the foregoing, income (loss) before income tax expense was a loss of ¥358 billion in the fiscal
year ended March 31, 2009 compared to income of ¥847 billion in the previous fiscal year. Income tax expense
increased by ¥90 billion to ¥762 billion in the fiscal year ended March 31, 2009 due mainly to an increase indeferred income tax expense. Income (loss) attributable to noncontrolling interests was a loss of ¥62 billion. As aresult, net income (loss) attributable to MHFG shareholders was a loss of ¥1,058 billion in the fiscal year ended
March 31, 2009 compared to income of ¥229 billion in the previous fiscal year.

Fiscal Year Ended March 31, 2010 Compared to Fiscal Year Ended March 31, 2009
Interest and dividend income decreased by ¥752 billion, or 31.5%, from the previous fiscal year to¥1,632 billion in the fiscal year ended March 31, 2010. Domestic interest and dividend income accounted for¥1,141 billion of the total amount, a decrease of ¥231 billion from the previous fiscal year, and foreign interestand dividend income accounted for ¥491 billion, a decrease of ¥521 billion from the previous fiscal year.
The decrease in domestic interest and dividend income was due mainly to the decrease in interest income
from domestic loans. The decrease in interest income from domestic loans was due mainly to the decrease inaverage yield, reflecting a decline in yen interest rate levels. Changes in average yields on domestic
interest-earning assets contributed to an overall decrease in interest and dividend income of ¥222 billion, andchanges in average balances of domestic interest-earning assets contributed to an overall decrease in interest anddividend income of ¥9 billion, resulting in the ¥231 billion decrease in domestic interest and dividend income.
The decrease in foreign interest and dividend income was due mainly to decreases in interest from foreignloans and income from foreign call loans and funds sold, and receivables under resale agreements and securities
borrowing transactions. The decreases in interest income from foreign loans and from foreign call loans andfunds sold, and receivables under resale agreements and securities borrowing transactions were due mainly to adecrease in average yields, reflecting general declines in U.S. dollar and euro interest rate levels. Changes inaverage yields on foreign interest-earning assets contributed to an overall decrease in interest and dividend
income of ¥515 billion, and changes in average balances of foreign interest-earning assets contributed to an
overall decrease in interest and dividend income of ¥6 billion, resulting in the ¥521 billion decrease in foreigninterest and dividend income.
Interest expense decreased by ¥574 billion, or 52.1%, from the previous fiscal year to ¥528 billion in thefiscal year ended March 31, 2010. Domestic interest expense accounted for ¥401 billion of the total amount, adecrease of ¥239 billion from the previous fiscal year, and foreign interest expense accounted for ¥127 billion of
the total amount, a decrease of ¥335 billion from the previous fiscal year.
The decrease in domestic interest expense was due mainly to decreases in interest expense on domestic
interest-bearing deposits and short-term borrowings. The decreases in interest expense on domestic
interest-bearing deposits and short-term borrowings were due mainly to a decrease in the average interest rate,
reflecting a decline in yen interest rate levels. The changes in average interest rates on domestic interest-bearing
liabilities contributed to an overall decrease in interest expense of ¥256 billion, and the changes in averagebalances of domestic interest-bearing liabilities contributed to an overall increase in interest expense of ¥17billion, resulting in the ¥239 billion decrease in domestic interest expense.
The decrease in foreign interest expense was due mainly to decreases in interest expense on foreign
short-term borrowings and foreign interest-bearing deposits. These decreases were due mainly to the decrease inaverage interest rates, reflecting general declines in U.S. dollar and euro interest rate levels. The changes inaverage interest rates on foreign interest-bearing liabilities contributed to an overall decrease in interest expenseof ¥338 billion, and the changes in average balances of foreign interest-bearing liabilities contributed to an
overall increase in interest expense of ¥3 billion, resulting in the ¥335 billion decrease in foreign interest
expense.
The decrease of 0.49% in the average yield on loans in the fiscal year ended March 31, 2010 compared to
the fiscal year ended March 31, 2009 was larger than the decrease of 0.40% in the average rate on interestbearing deposits over the same period. Taking into account only domestic loans and domestic deposits, thedifference between the decrease of 0.21% in the average yield on domestic loans and the decrease of 0.22% in
the average rate on domestic interest-bearing deposits was not significant.
As a result of the foregoing, net interest income decreased by ¥178 billion, or 13.9%, from the previous
fiscal year to ¥1,104 billion. Average interest rate spread decreased by 0.12% to 0.75%, with the domestic
71average interest rate spread remaining unchanged due mainly to a comparable decrease in the average interest
rate on deposits and the decrease in average yield on loans, both of which reflect declining yen interest ratelevels, and foreign average interest rate spread decreasing by 0.15% due mainly to the effect of the decrease inaverage yield on loans exceeding the effect of the decrease in average interest rate on deposits, both of whichreflects declining U.S. dollar and euro interest rate levels.
Fiscal Year Ended March 31, 2009 Compared to Fiscal Year Ended March 31, 2008
Interest and dividend income decreased by ¥726 billion, or 23.3%, from the previous fiscal year to ¥2,384
billion in the fiscal year ended March 31, 2009. Domestic interest and dividend income accounted for ¥1,372
billion of the total amount, a decrease of ¥38 billion from the previous fiscal year, and foreign interest anddividend income accounted for ¥1,012 billion, a decrease of ¥688 billion from the previous fiscal year.
The decrease in domestic interest and dividend income was due mainly to the decrease in interest anddividend income from domestic investments and interest-bearing deposits in other banks. The decrease in interestand dividend income from domestic investments was due to a decrease in the average balance of domestic
investments of ¥1,428 billion, due mainly to the decrease in the balance of equity securities reflecting declines indomestic stock prices and the balance of debt securities as a result of the turmoil in the financial markets. The
decrease in interest income from domestic interest-bearing deposits in other banks was due mainly to thedecrease in average yield, reflecting a decline in yen interest rate levels. The changes in the average yields on
domestic interest-earning assets contributed to an overall decrease in interest and dividend income of ¥50 billion,
and the changes in average balances of domestic interest-earning assets contributed to an overall increase ininterest and dividend income of ¥12 billion, resulting in the ¥38 billion decrease in domestic interest anddividend income.
The decrease in foreign interest and dividend income was due mainly to decreases in interest and dividend
income from foreign call loans and funds sold, and receivables under resale agreements and securities borrowing
transactions and foreign investments, offset in part by an increase in interest income from foreign trading accountassets. The decrease in interest income from foreign call loans and funds sold, and receivables under resaleagreements and securities borrowing transactions was due mainly to a decrease in average yields, reflecting
general declines in U.S. dollar and euro interest rate levels. The decrease in interest and dividend income fromforeign investments and the increase in interest income from foreign trading account assets was due mainly to thereclassification from investments to trading account assets of foreign currency denominated available-for-salesecurities that were elected for fair value treatment under ASC 825 as of April 1, 2008. For further informationon the fair value option, see note 29 to our consolidated financial statements included elsewhere in this annual
report. The changes in average yields on foreign interest-earning assets contributed to an overall decrease ininterest and dividend income of ¥508 billion, and the changes in average balances of foreign interest-earning
assets contributed to an overall decrease in interest and dividend income of ¥180 billion, resulting in the ¥688
billion decrease in foreign interest and dividend income.
Interest expense decreased by ¥810 billion, or 42.3%, from the previous fiscal year to ¥1,102 billion in thefiscal year ended March 31, 2009. Domestic interest expense accounted for ¥640 billion of the total amount, adecrease of ¥75 billion from the previous fiscal year, and foreign interest expense accounted for ¥462 billion of
the total amount, a decrease of ¥735 billion from the previous fiscal year.
The decrease in domestic interest expense was due mainly to a decrease in interest expense on domestic
interest-bearing deposits. The decrease in interest expense on domestic interest-bearing deposits was due to adecrease in the average interest rate, reflecting a decline in yen interest rate levels. The changes in averageinterest rates on domestic interest-bearing liabilities contributed to an overall decrease in interest expense of ¥102
billion, and the changes in average balances of domestic interest-bearing liabilities contributed to an overall
increase in interest expense of ¥27 billion, resulting in the ¥75 billion decrease in domestic interest expense.
72

The decrease in foreign interest expense was due mainly to decreases in interest expense on foreign shortterm borrowings and foreign interest-bearing deposits. These decreases were due mainly to the decrease inaverage interest rates, reflecting general declines in U.S. dollar and euro interest rate levels. The changes inaverage interest rates on foreign interest-bearing liabilities contributed to an overall decrease in interest expenseof ¥519 billion, and the changes in average balances of foreign interest-bearing liabilities contributed to an
overall decrease in interest expense of ¥216 billion, resulting in the ¥735 billion decrease in foreign interest
expense.
The decrease of 0.27% in the average yield on loans in the fiscal year ended March 31, 2009 compared to
the fiscal year ended March 31, 2008 was smaller than the decrease of 0.36% in the average rate on interestbearing deposits over the same period. Taking into account only domestic loans and domestic deposits, thedifference between the decrease of 0.05% in the average yield on domestic loans and the decrease of 0.09% in
the average rate on domestic interest-bearing deposits was not significant.
As a result of the foregoing, net interest income increased by ¥84 billion, or 7.0%, from the previous fiscal
year to ¥1,282 billion. Average interest rate spread rose by 0.12% to 0.87%, with domestic average interest rate
spread rising by 0.06%, due mainly to a decrease in average interest rate on deposits, which more than offset theeffect of a decrease in average yield on loans, both of which reflect declining yen interest rate levels, and foreign
average interest rate spread rising by 0.58% due mainly to the effect of the decrease in average interest rate on
deposits exceeding the effect of the decrease in average yield on loans, both of which reflects declining U.S.
dollar and euro interest rate levels.
Provision (Credit) for Loan Losses
Fiscal Year Ended March 31, 2010 Compared to Fiscal Year Ended March 31, 2009
Provision for loan losses decreased by ¥345 billion, or 60.8%, from the previous fiscal year to ¥222 billion
in the fiscal year ended March 31, 2010. The decrease was due mainly to an improvement in economic
conditions and our efforts for appropriate credit management. See “—Financial Condition—Assets—Allowancefor Loan Losses—Provision for loan losses.”
Fiscal Year Ended March 31, 2009 Compared to Fiscal Year Ended March 31, 2008
We had a provision for loan losses of ¥567 billion in the fiscal year ended March 31, 2009 compared to acredit for loan losses of ¥58 billion in the previous fiscal year. The provision for loan losses was due mainly todeclines in the financial condition of domestic SMEs and middle-market corporations, the effect of the collapseof Lehman Brothers on our exposures to related entities and the weakening credit status of overseas loans
reflecting the global economic downturn, as well as increased estimated loss rates related to normal obligors. See“—Financial Condition—Assets—Allowance for Loan Losses—Provision (credit) for loan losses.”73

Fiscal Year Ended March 31, 2010 Compared to Fiscal Year Ended March 31, 2009
Noninterest income increased by ¥879 billion from the previous fiscal year to ¥1,331 billion in the fiscal
year ended March 31, 2010. The increase was due mainly to gains in investment gains (losses)—net of ¥67
billion in the fiscal year ended March 31, 2010 compared to losses in investment gains (losses)—net of ¥462
billion in the previous fiscal year and an increase in trading account gains—net of ¥300 billion.
Fees and commissions
Fees and commissions income increased by ¥25 billion, or 4.5%, from the previous fiscal year to ¥586
billion in the fiscal year ended March 31, 2010. The increase was due mainly to an increase of ¥58 billion in fees
and commissions from securities-related business, offset in part by a decrease of ¥15 billion in fees andcommissions from deposits, debentures and lending business. The increase in fees and commissions fromsecurities-related business was due mainly to an increase in fees of our securities subsidiaries as a result of apositive change in market conditions.
Foreign exchange gains (losses)—net
Foreign exchange gains (losses)—net was a loss of ¥2 billion in the fiscal year ended March 31, 2010
compared to a gain of ¥24 billion in the previous fiscal year. The change was due mainly to fluctuations inforeign exchange rates in the fiscal year ended March 31, 2010.
Trading account gains—net
Trading account gains—net increased by ¥300 billion from the previous fiscal year to ¥422 billion in thefiscal year ended March 31, 2010. The increase was due mainly to the gains earned by consolidated VIEs, suchas stock investment trusts, as a result of a positive change in market conditions, an increase in gains related tochanges in the fair value of derivative financial instruments used to hedge market risks, mainly interest rate risk,74

that are not eligible for hedge accounting under U.S. GAAP and an increase in gains related to changes in the fairvalue of foreign currency denominated available-for-sale securities for which the fair value option was elected.
For further information on the fair value option, see note 29 to our consolidated financial statements included
elsewhere in this annual report.
Investment gains (losses)—net
Investment gains (losses)—net was a gain of ¥67 billion in the fiscal year ended March 31, 2010 compared
to a loss of ¥462 billion in the previous fiscal year. The change was due mainly to investment gains related toequity securities of ¥55 billion recorded in the fiscal year ended March 31, 2010 compared to investment losses
related to equity securities of ¥282 billion in the previous fiscal year as well as a decrease of ¥176 billion in
investment losses related to bonds compared to the previous fiscal year. The change in investment gains (losses)
related to equity securities between the fiscal year ended March 31, 2009 and the fiscal year ended March 31,
2010 was due mainly to a decrease in impairment losses on equity securities as a result of a recovery of the stock
markets. The decrease in investment losses related to bonds in the fiscal year ended March 31, 2010 was due
mainly to the absence of impairment losses on Japanese government bonds as we adopted ASC 320 whichamends the other-than-temporary impairment model for debt securities. For further information, see notes 2 and
5 to our consolidated financial statements included elsewhere in this report.
Gains on disposal of premises and equipment
Gains on disposal of premises and equipment increased by ¥5 billion, or 21.7%, from the previous fiscal
year to ¥28 billion in the fiscal year ended March 31, 2010 due mainly to increased gains on the sale of realestate.
Other noninterest income
Other noninterest income increased by ¥46 billion, or 25.0%, from the previous fiscal year to ¥230 billion in
the fiscal year ended March 31, 2010. The increase was due mainly to a gain relating to the merger of Mizuho
Securities and Shinko Securities.
Fiscal Year Ended March 31, 2009 Compared to Fiscal Year Ended March 31, 2008
Noninterest income decreased by ¥643 billion, or 58.7%, from the previous fiscal year to ¥452 billion in thefiscal year ended March 31, 2009. The decrease was due mainly to a decrease in foreign exchange gains—net of¥273 billion, an increase in investment losses—net of ¥271 billion and a decrease in fees and commissions of¥72 billion.
Fees and commissions
Fees and commissions income decreased by ¥72 billion, or 11.5%, from the previous fiscal year to ¥561
billion in the fiscal year ended March 31, 2009. The decrease was due mainly to a decrease of ¥43 billion in feesfor other customer services and a decrease of ¥38 billion in fees and commissions from securities-related
business, offset in part by an increase of ¥22 billion in fees and commissions from deposits, debentures andlending business. The decrease in fees for other customer services was due mainly to a decrease in trust businessrelated fees other than those included in trust fees such as brokerage fees related to real estate transactions andother fees and commissions such as sales agency fees related to insurance products including individual
annuities. The decrease in fees and commissions from securities-related business was due mainly to decreases inunderwriting commissions related to private offerings of debt securities and sales commissions related toinvestment trusts which were negatively impacted by adverse market conditions, including declines in domestic
stock markets. The increase in fees and commissions from deposits, debentures and lending business was due
mainly to recognition of deferred fees in connection with the loans reclassified from the held-for-sale accountduring this fiscal year and an increase in fee income associated with domestic syndicated loans reflecting theincreased funding needs of domestic corporate customers.

Foreign exchange gains (losses)—net
Foreign exchange gains—net decreased by ¥273 billion, or 92.0%, from the previous fiscal year to ¥24
billion in the fiscal year ended March 31, 2009. The decrease was due mainly to translation gains with respect toforeign currency denominated liabilities in the fiscal year ended March 31, 2008 that were funded and incurred tooffset foreign exchange risk related to foreign currency denominated available-for-sale securities. In the fiscal
year ended March 31, 2009, the translation gains with respect to foreign currency denominated liabilities wereoffset by translation losses on foreign currency denominated available-for-sale securities as a result of thereclassification of foreign currency denominated available-for-sale securities from investments to trading accountassets following the adoption of the fair value option under ASC 825 as of April 1, 2008. In the previous fiscal
year, the translation losses on foreign currency denominated available-for-sale securities were recorded in othercomprehensive income. For further information on the fair value option, see note 29 to our consolidated financial
statements included elsewhere in this annual report.
Trading account gains—net
Trading account gains—net decreased by ¥14 billion, or 10.3%, from the previous fiscal year to ¥122 billion
in the fiscal year ended March 31, 2009. The decrease was due mainly to the decrease in gains related to changes
in the fair value of derivative financial instruments used to hedge market risks, mainly interest rate risk, that are
not eligible for hedge accounting under U.S. GAAP and the losses incurred by consolidated VIEs, such as stock
investment trusts, due mainly to declines in the stock markets. Trading account gains—net also include losses
related to changes in the fair value of foreign currency denominated available-for-sale securities that were elected
for fair value treatment under ASC 825 as of April 1, 2008. For further information on the fair value option, seenote 29 to our consolidated financial statements included elsewhere in this annual report. The increase in theselosses was offset in part by the decrease in the trading losses on securitization products incurred by Mizuho
Securities, including overseas subsidiaries, in connection with the dislocation in the global financial markets. See“—Overview—Impact of the Dislocation in the Global Financial Markets.”
Investment losses—net
Investment losses—net increased by ¥271 billion from the previous fiscal year to ¥462 billion in the fiscal
year ended March 31, 2009. The increase was due mainly to investment losses related to equity securities of ¥282
billion in the fiscal year ended March 31, 2009, compared to investment gains related to equity securities of ¥121
billion in the previous fiscal year, offset in part by a decrease in investment losses related to bonds of ¥136
billion from the previous fiscal year to ¥178 billion in the fiscal year ended March 31, 2009. The investment
losses related to equity securities in the fiscal year ended March 31, 2009 were due mainly to an increase inimpairment losses on and a decrease in gains on sales of equity securities reflecting declines in domestic andoverseas stock markets. The decrease in investment losses related to bonds was due mainly to reclassification of
investment losses related to foreign currency denominated available-for-sale securities from investments gains(losses) to trading account gains (losses) following the adoption of the fair value option under ASC 825 as ofApril 1, 2008. Investment losses related to bonds for both fiscal years also include the losses on sales of, andimpairment losses on various types of, securitization products due to the impact of the dislocation in the global
financial markets. See “—Overview—Impact of the Dislocation in the Global Financial Markets.”

Salaries and employee benefits
Salaries and employee benefits increased by ¥96 billion, or 19.4%, from the previous fiscal year to ¥592
billion in the fiscal year ended March 31, 2010 due mainly to the effect of increased employee retirement benefit
expenses as a result of a decline 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 period, and the amortization of net actuarial loss,
which primarily reflects past declines in the value of plan assets. Additional information regarding pension andother employee benefit plans is included in note 22 to our consolidated financial statements included elsewherein this annual report.
General and administrative expenses
General and administrative expenses decreased by ¥2 billion, or 0.4%, from the previous fiscal year to ¥497
billion in the fiscal year ended March 31, 2010. The decrease was due mainly to our efforts to enhance our cost
efficiency through detailed reviews.

Noninterest expenses increased by ¥21 billion, or 1.4%, from the previous fiscal year to ¥1,525 billion in thefiscal year ended March 31, 2009. The increase was due mainly to an increase in provision for losses on
off-balance-sheet instruments of ¥79 billion and an increase in salaries and employee benefits of ¥60 billion,
offset in part by a decrease in impairment of goodwill of ¥50 billion and a decrease in other noninterest expensesof ¥35 billion.
Salaries and employee benefits
Salaries and employee benefits increased by ¥60 billion, or 13.7%, from the previous fiscal year to ¥496
billion in the fiscal year ended March 31, 2009 due mainly to the effect of increased employee retirement benefit

billion in the fiscal year ended March 31, 2009. The decrease was due mainly to our efforts to enhance our cost

further enhancement to our infrastructure to promote our domestic consulting activities with individuals.
Impairment of goodwill
We did not record impairment of goodwill in the fiscal year ended March 31, 2009. Impairment of goodwillof ¥50 billion was incurred in the fiscal year ended March 31, 2008 due to the carrying amount of Mizuho
Investors Securities and Mizuho Securities, each a subsidiary of ours, exceeding their fair value as a result of adecrease in the market price of common stock of Mizuho Investors Securities and decreased future cash flows
estimation of Mizuho Securities. Additional information regarding the impairment of goodwill is included in note
9 to our consolidated financial statements included elsewhere in this annual report.
Occupancy expenses
Occupancy expenses decreased by ¥19 billion, or 9.7%, from the previous fiscal year to ¥178 billion in thefiscal year ended March 31, 2009. The decrease was due mainly to an increase in depreciation expenses in thefiscal year ended March 31, 2008 as a result of a change in the declining-balance method for depreciating
premises and equipment, along with a reduction of the estimated salvage values of the relevant assets.
Provision (credit) for losses on off-balance-sheet instruments
Provision for losses on off-balance-sheet instruments increased by ¥79 billion from the previous fiscal yearto ¥84 billion in the fiscal year ended March 31, 2009. The increase was due mainly to an increase in allowance
for losses on off-balance-sheet transactions primarily as a result of downgrades in credit ratings of some obligors
reflecting declines in their financial condition.
Other noninterest expenses
Other noninterest expenses decreased by ¥35 billion, or 17.1%, from the previous fiscal year to ¥162 billion
in the fiscal year ended March 31, 2009. The decrease was due mainly to the decrease in valuation losses related
to loans held for sale mainly in connection with overseas leveraged buyout financings from ¥60 billion in the78

previous fiscal year to ¥38 billion in the fiscal year ended March 31, 2009 as a result of the decrease in theoutstanding balance of loans held for sale which remained unsold due to the impact of the dislocation in the
global financial markets.

Business Segments Analysis
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 theperformance of each of our operating segments primarily in terms of “net business profits” following internalmanagerial accounting rules and practices. Net business profits is used as a measure of the profitability of corebanking operations in Japan 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 andadministrative expenses (excluding non-recurring expenses). Measurement by net business profits is required forregulatory 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 31 to our consolidated financial statements included
elsewhere in this annual report.

Fiscal year ended March 31, 2010 compared to the fiscal year ended March 31, 2009
Gross profits for Mizuho Corporate Bank for the fiscal year ended March 31, 2010 were ¥642.3 billion, an
increase of ¥114.1 billion, or 21.6%, compared to the fiscal year ended March 31, 2009. This increase was due toan increase in gross profits from trading and others of ¥116.6 billion (including an increase of approximately ¥61
billion (which is eliminated upon consolidation) due to the effect of, based on the structure of our capital raising84

through the issuance of preferred debt securities by our special purpose companies, Mizuho Financial Group,
instead of Mizuho Corporate Bank, providing funds for the dividend payments made on such preferred debt
securities specifically during the fiscal year ended March 31, 2010) as a result of an absence of losses on credit
investments, such as equity investment trusts, we recorded in the fiscal year ended March 31, 2009 and robust
profits from flexible and timely asset-and-liability management operations, and an increase in gross profits fromdomestic operations of ¥10.5 billion due primarily to an increase in non-interest income due to absence ofimpairment losses related to alternative investments recorded in the previous year and an increase in interest
income as a result of a widening of the domestic average loan interest rate spread. This increase was offset in partby a decrease of ¥13.0 billion in gross profits from international operations, due mainly to a decrease in
non-interest income reflecting increased valuation losses from credit default swaps related to credit investments
in Europe and a decrease in interest income reflecting a decline in total loan balance.
General and administrative expenses of Mizuho Corporate Bank for the fiscal year ended March 31, 2010
were ¥246.9 billion, which was unchanged from the fiscal year ended March 31, 2009, due mainly to the effect of
the appreciation of the Japanese yen in addition to our group-wide cost reduction efforts offset in part by anincrease in expenses related to employee retirement benefits.
As a result, net business profits of Mizuho Corporate Bank for the fiscal year ended March 31, 2010 were¥395.4 billion, an increase of ¥114.1 billion, or 40.6%, compared to the fiscal year ended March 31, 2009.
Net business profits of Mizuho Securities for the fiscal year ended March 31, 2010 were ¥24.4 billion, an
increase of ¥15.6 billion compared to the fiscal year ended March 31, 2009 due mainly to an increase incommission and fee income and improved trading profits, including the effects of the merger between the former
Shinko Securities and the former Mizuho Securities on May 7, 2009.
As a result mainly of the foregoing, net business profits for the Global Corporate Group for the fiscal year
ended March 31, 2010 increased by ¥122.9 billion, or 39.9%, compared to the fiscal year ended March 31, 2009
to ¥430.6 billion.
Fiscal year ended March 31, 2009 compared to fiscal year ended March 31, 2008
Gross profits for Mizuho Corporate Bank for the fiscal year ended March 31, 2009 decreased by ¥78.2
billion, or 12.9%, from the previous fiscal year to ¥528.2 billion. This decrease was due to a decrease of ¥11.3
billion in domestic operations reflecting a decrease in domestic loan interest income and a decrease of ¥10.9
billion in international operations as a result of a decrease in non-interest income due to the dislocation in global
financial markets. Given the severe market environment, losses in credit investments such as on equity
investment trusts and a ¥11.4 billion decrease in dividends from Mizuho Securities resulted in a decrease of¥56.0 billion in gross profits of trading and others. These decreases were offset in part by an increase in fees fromsyndicated loans due to our responding promptly and appropriately to the needs of our customers that required
substitutes for commercial paper and corporate bond financing.
General and administrative expenses of Mizuho Corporate Bank for the fiscal year ended March 31, 2009
increased by ¥10.7 billion, or 4.5%, from the previous fiscal year to ¥246.9 billion due mainly to an increase inemployee retirement benefit expenses.
Mizuho Securities recorded net business profits of ¥8.8 billion compared to net business losses of ¥30.3
billion due mainly to the increase in bond trading profits and the effects of its business reform program that
decreased general and administrative expenses offset in part by a decrease in stock and corporate bondcommissions as a result of sluggish market environment.
Net business profits for “others” were ¥17.6 billion compared to net business losses of ¥398.0 billion in theprevious fiscal year due mainly to the losses incurred in the CDO business in the previous fiscal year by anoverseas subsidiary of Mizuho Securities.
85

As a result mainly of the foregoing, net business profits for the Global Corporate Group for the fiscal year
ended March 31, 2009 were ¥307.7 billion compared to net business losses of ¥58.1 billion in the previous fiscal
year.

Fiscal year ended March 31, 2010 compared to fiscal year ended March 31, 2009
Gross profits for Mizuho Bank for the fiscal year ended March 31, 2010 decreased by ¥8.9 billion, or 1.1%,
from the fiscal year ended March 31, 2009 to ¥818.8 billion. The decrease was due mainly to a decrease in grossprofits of ¥64.0 billion from retail banking, reflecting a decrease in loan interest income and deposit income andincome from sales of individual annuities, offset in part by an increase in sales of investment trusts. Gross profits
from corporate banking also decreased by ¥49.4 billion, reflecting a decrease in loan interest income and deposit
income as well as a decrease in non-interest income such as from our solutions business and foreign exchange
business such as currency options. These decreases were offset in part by an increase in gross profits of ¥104.5
billion from trading and others (including an increase of approximately ¥17 billion (which is eliminated upon
consolidation) due to the effect of, based on the structure of our capital raising through the issuance of preferreddebt securities by our special purpose companies, Mizuho Financial Group, instead of Mizuho Bank, providing
funds for the dividend payments made on such preferred debt securities specifically during the fiscal year ended
March 31, 2010) as a result of robust profits from flexible and timely asset-and-liability management operations
mainly in Japanese yen in response to interest rate movements.
General and administrative expenses for Mizuho Bank decreased by ¥0.7 billion, or 0.1%, compared to thefiscal year ended March 31, 2009 to ¥570.4 billion due mainly to our group-wide cost reduction efforts offset inpart by an increase in expenses related to employee retirement benefits.
As a result, net business profits of Mizuho Bank for the fiscal year ended March 31, 2010 were ¥248.4
billion, a decrease of ¥8.2 billion, or 3.2%, compared to the fiscal year ended March 31, 2009.
Mizuho Investors Securities recorded net business profits of ¥7.6 billion for the fiscal year ended March 31,
2010, compared to net business losses of ¥12.7 billion for the fiscal year ended March 31, 2009, due mainly to anincrease in commission income such as equity-related income and sales of investment trust and an increase in
trading income with the absence of the negative impact of the global financial crisis incurred in the previous
fiscal year and a decrease in general and administrative expenses through cost-cutting efforts.
As a result mainly of the foregoing, net business profits for the Global Retail Group for the fiscal year ended
March 31, 2010 increased by ¥10.1 billion, or 3.7%, compared to the fiscal year ended March 31, 2009 to ¥280.7

Fiscal year ended March 31, 2009 compared to fiscal year ended March 31, 2008
Gross profits for Mizuho Bank for the fiscal year ended March 31, 2009 decreased by ¥115.1 billion, or
12.2%, from the previous fiscal year to ¥827.7 billion. This decrease was due to a decrease in gross profits of¥1.2 billion from retail banking, reflecting decreases in income from loans and fee income from sales ofinvestment trusts and individual annuities due to the weakness in stock markets, and a decrease of ¥61.1 billion
from corporate banking, reflecting decreases in income from loans and net noninterest income from our solutions
business, foreign exchange business and others. In addition, gross profits from trading and others decreased by¥52.8 billion due mainly to a decline in trading income and from our conservative asset-and-liabilitymanagement operations. These decreases were offset in part by an improvement in the profitability of deposits
due to an increase in outstanding balances and other factors.
General and administrative expenses for Mizuho Bank increased by ¥33.9 billion, or 6.3%, from theprevious fiscal year to ¥571.1 billion due mainly to an increase in employee retirement benefit expenses.
Mizuho Investors Securities incurred net business losses of ¥12.7 billion compared to net business profits of¥7.8 billion in the previous fiscal year due mainly to a decrease in commission income from its stock brokeragebusiness as a result of weak domestic stock markets, sluggish foreign bond sales and write-downs of
yen-denominated samurai bonds issued by Lehman Brothers.
As a result mainly of the foregoing, net business profits for the Global Retail Group for the fiscal year ended
March 31, 2009 decreased by ¥173.7 billion, or 39.1%, from the previous fiscal year to ¥270.6 billion.

Fiscal Year Ended March 31, 2010 Compared to Fiscal Year Ended March 31, 2009
In the fiscal year ended March 31, 2010, 74.9% of our net income was derived from Japan, 14.3% from theAmericas, 6.3% from Europe and 4.5% from Asia/Oceania, excluding Japan, and others. At March 31, 2010,
76.8% of total assets were allocated to Japan, 13.9% to the Americas, 6.4% to Europe and 2.9% to Asia/Oceania,
excluding Japan, and others.
Total revenue in Japan increased by ¥457 billion from the previous fiscal year due primarily to the change
from investment losses—net to investment gains—net, as a result of a decrease in impairment losses on equity
securities reflecting a recovery of the domestic stock markets, and absence of impairment losses on Japanese
government bonds as we adopted ASC 320 which amends the other-than-temporary impairment model for debt
securities. Total expenses decreased by ¥517 billion due to a decrease in provision for loan losses, reflecting an
improvement in Japanese economic conditions, and a decrease in interest expense on domestic interest-bearing
deposits, reflecting a decline in yen interest rate levels. In addition, we had an income tax benefit of ¥367 billion
in Japan in the fiscal year ended March 31, 2010 compared to an income tax expense of ¥720 billion in theprevious fiscal year. The tax benefit was due mainly to an increase in deferred tax assets, net of valuation
allowance, reflecting primarily changes in our estimation of future taxable income as a result of the increase in
net unrealized gains on available-for-sale securities, reflecting primarily the rise in domestic stock markets. As aresult, net income in Japan increased by ¥2,061 billion. Total assets in Japan increased by ¥5,967 billion due
primarily to increases in investments, especially Japanese government bonds, and trading account assets, offset inpart by a decrease in loans.
In the Americas, total revenue decreased by ¥140 billion due primarily to a decrease in interest income fromreceivables under resale agreements, investments and loans, reflecting general declines in U.S. dollar interest ratelevels, offset in part by the change from trading account losses—net to trading account gains—net. Total
expenses decreased by ¥129 billion due primarily to a decrease in interest expenses from receivables under resaleagreements reflecting general declines in U.S. dollar interest rate levels. As a result, net income in the Americas
increased by ¥18 billion. Total assets in the Americas decreased by ¥3,044 billion due primarily to a decrease in
trading account assets, consisting mainly of those regarding derivative contracts and the effect of the depreciationof U.S. dollars against the Japanese yen.
In Europe, total revenue decreased by ¥117 billion due primarily to a decrease in interest income fromloans, investments and receivables under resale agreements, reflecting general declines in euro interest ratelevels, offset in part by a decrease in trading account losses—net. Total expenses decreased by ¥201 billion due
primarily to decreases in interest expense on interest-bearing deposits and interest expense from receivables
under resale agreements, reflecting general declines in euro interest rate levels. As a result, net income in Europe
increased by ¥86 billion. Total assets in Europe increased by ¥363 billion due primarily to increases ininvestments and receivables under resale agreements, partially offset by decreases in trading account assets andloans and the effect of the depreciation of the euro against the Japanese yen.
In Asia/Oceania excluding Japan, and others, total revenue decreased by ¥73 billion due primarily to adecrease in loan interest income. Total expenses decreased by ¥71 billion due primarily to decreases in interest
expenses and provision for loan losses. As a result, net income in Asia/Oceania excluding Japan, and others
increased by ¥2 billion. Total assets in Asia/Oceania excluding Japan, and others decreased by ¥18 billion due
primarily to decreases in trading account assets and loans, partially offset by an increase in investments.
Fiscal Year Ended March 31, 2009 Compared to Fiscal Year Ended March 31, 2008
In the fiscal year ended March 31, 2009, we recorded a net loss in Japan and Europe. Among thegeographical regions in which we recorded net income, 73.9% of the net income was derived from the Americas
and 26.1% from Asia/Oceania, excluding Japan, and others. At March 31, 2009, 74.5% of total assets wereallocated to Japan, 16.1% to the Americas, 6.3% to Europe and 3.1% to Asia/Oceania, excluding Japan, andothers.
91

Total revenue in Japan decreased by ¥1,148 billion from the previous fiscal year due primarily to anincrease in investment losses—net, as a result of an increase in impairment losses on, and a decrease in gains onsales of, equity securities reflecting declines in domestic stock markets, and a decrease in foreign exchange gains
as a result of translation gains with respect to foreign currency denominated liabilities that were funded andincurred to offset foreign exchange risk related to foreign currency denominated available-for-sale securities in
the fiscal year ended March 31, 2008. In the fiscal year ended March 31, 2009, the translation gains with respect
to foreign currency denominated liabilities were offset by translation losses on foreign currency denominatedavailable-for-sale securities as a result of the reclassification of foreign currency denominated available-for-salesecurities from investments to trading account assets following the adoption of the fair value option under ASC
825 as of April 1, 2008. In the previous fiscal year, the translation losses on foreign currency denominatedavailable-for-sale securities were recorded in other comprehensive income. Total expenses increased by ¥522
billion due to an increase in provision for loan losses, reflecting the effects of the rapid deterioration ofmacroeconomic conditions in Japan as a result of the global recession, worsening business environment andeconomic condition surrounding domestic companies, and abrupt bankruptcies of real estate companies. As aresult, net income in Japan decreased by ¥1,754 billion. Total assets in Japan decreased by ¥126 billion due
primarily to decreases in receivables under securities borrowing transactions and trading account assets, offset inpart by an increase in loans as corporate borrowing increased during the financial market turmoil.
In the Americas, total revenue decreased by ¥409 billion due primarily to a decrease in interest income as aresult of decreases in average yields reflecting general declines in U.S. dollar interest rate levels, offset in part bya decrease in investment losses—net, as the impairment losses on various types of securitization products due tothe impact of the dislocation in the global financial markets significantly decreased compared to the previous
fiscal year. Total expenses decreased by ¥446 billion due primarily to a decrease in interest expenses reflecting
general declines in U.S. dollar interest rate levels. As a result, net income in the Americas increased by ¥27
billion. Total assets in the Americas increased by ¥5,969 billion due primarily to an increase in trading accountassets, consisting mainly of those regarding derivative contracts, offset in part by a decrease in investments due
primarily to the reclassification to trading account assets as a result of the adoption of the fair value option under
ASC 825.
In Europe, total revenue increased by ¥254 billion due primarily to the decrease in losses incurred in the
trading account and investments during the previous fiscal year affected by the impact of the dislocation in the
global financial markets, offset in part by a decrease in interest income as a result of decreases in average yields
reflecting general declines in euro interest rate levels. Total expenses decreased by ¥216 billion due primarily toa decrease in interest expenses reflecting general declines in euro interest rate levels. As a result, net income inEurope increased by ¥471 billion. Total assets in Europe decreased by ¥1,674 billion due primarily to a decrease
in investments, which included a reclassification to trading account assets as a result of the adoption of ASC 825,
and a decrease in receivables under resale agreements, partially offset by an increase in trading account assets.
In Asia/Oceania excluding Japan, and others, total revenue decreased by ¥66 billion due primarily todecreases in interest income and trading account gains—net, offset in part by an increase in foreign exchange
gains—net. Total expenses decreased by ¥24 billion due primarily to a decrease in interest expenses, offset inpart by an increase in provision for loan losses. As a result, net income in Asia/Oceania excluding Japan, andothers decreased by ¥39 billion. Total assets in Asia/Oceania excluding Japan, and others decreased by ¥404
billion due primarily to a decrease in investments which included reclassification as a result of the adoption of
ASC 825, and a decrease in loans, partially offset by an increase in trading account assets.

¥72,657¥63,783¥(8,874)1.0

100.0% (8,884) —Notes:(1) Following the revision of Japan Standard Industrial Classification, we partially changed the classification ofindustries as of March 31, 2010. The change consisted primarily of a reclassification of loans to private
lessors of apartments, which were previously primarily categorized by the industry of the relevant borrower,
to “real estate.” Amounts as of March 31, 2009 have been reclassified to conform to the presentation as ofMarch 31, 2010.
(2) “Other industries” within domestic and “other” within foreign include trade receivables and leasereceivables of consolidated VIEs.
Total loans before allowance for loan losses decreased by ¥8,874 billion from the end of the previous fiscal
year to ¥63,783 billion as of March 31, 2010. Domestic loans decreased by ¥6,868 billion to ¥54,578 billion due
mainly to a decrease in loans to government and public institutions attributable mainly to loans to the Japanese
government. Domestic loans decreased in almost all of the industries as funding needs of large corporate
borrowers, their affiliates and others eased compared to the end of the previous fiscal year.

94

Loans to foreign borrowers decreased by ¥2,016 billion from the end of the previous fiscal year to ¥9,283
billion as of March 31, 2010. Foreign loans decreased in all of the categories due mainly to the translation impactof the strengthening of the Japanese yen and our appropriate credit management reflecting the continuing
stagnation of overseas economies.
Within our loan portfolio, loans to domestic borrowers increased from 84.5% to 85.5% while loans toforeign borrowers decreased from 15.5% to 14.5%.
Impaired Loans
Japanese banks are required to categorize obligors into the groups listed below based on their financial
condition and other factors and then to classify loans and off-balance-sheet instruments against obligors, taking
into consideration the risk of collection and risk of impairment. We refer to this categorization and classification
process as the self-assessment procedures which are conducted in conjunction with our credit rating system.
Through the self-assessment procedures, we categorize obligors into the following categories:•

normal: Obligors for which business conditions are favorable and are deemed not to have any particular
problems in terms of their financial position.

•

watch: Obligors that require observation going forward because of either concerns regarding theirfinancial position or weak or unstable business conditions.

•special attention: Among watch obligors, those having difficulty meeting loan conditions, such as
reduced or suspended interest payments, or those in default of payment obligations such as failure to
make principal or interest payments beyond a specified period.

•

intensive control: Obligors that are not yet bankrupt but are in financial difficulties and are deemed
likely to become bankrupt in the future because of failure to make progress in implementing their
management improvement plans or other measures (including obligors that are receiving ongoingsupport from financial institutions).

•

substantially bankrupt: Obligors that have not yet become legally or formally bankrupt but are
effectively insolvent because they are in serious financial difficulties and are deemed to be not capableof restructuring.

•bankrupt: Obligors that have become legally or formally bankrupt.

We consider both loans that are subject to impairment under ASC 310, “Receivables” and small balance,
homogeneous loans to be impaired when it is probable that we will be unable to collect all the scheduled
payments of principal and interest when due according to the contractual terms of the loan. Restructured loans
and loans that are 90 days or more delinquent are generally considered to be impaired. We determine loans to
special attention, intensive control, substantially bankrupt and bankrupt obligors as impaired loans in connection
with our consideration of collectibility mentioned above. All of our impaired loans are designated as nonaccrualloans. See “Item 11. Quantitative and Qualitative Disclosures about Market Risk—Credit Risk Management” fordescriptions of our self-assessment procedures and our internal credit rating system.
We endeavor to remove impaired loans from our balance sheet within three years of their being so
categorized through methods such as collection, charge-offs, disposal and improving the borrowers’ credit rating
through restructuring efforts.

Impaired loans decreased by ¥28 billion, or 1.9%, from the end of the previous fiscal year to ¥1,404 billion
as of March 31, 2010. Domestic impaired loans decreased by ¥43 billion due primarily to decreases in impairedloans to borrowers in the real estate industry, the services industry and the construction industry, each due
primarily to charge-offs, restructurings and collections, related to large borrowers, offset in part by an increase in
the manufacturing industry due primarily to downgrades in internal credit ratings to large borrowers, and anincrease in individuals. Foreign impaired loans increased by ¥15 billion, reflecting the continuing stagnation ofoverseas economies.
The percentage of impaired loans within gross total loans increased from 2.0% as of March 31, 2009 to
2.2% as of March 31, 2010. The percentage of impaired loans net of allowance to gross total loans net ofallowance increased from 0.78% as of March 31, 2009 to 0.83% as of March 31, 2010, as the percentage
decrease of gross total loans was larger than that of impaired loans.
Allowance for Loan Losses
Calculation of allowance for loan losses
Our self-assessment and credit-rating procedures serve as the basis for determining the amount of theallowance for loan losses. The specific methods of calculating the allowance for each category of obligors are as
follows:
Normal and watch obligors . . . . . . . . . . . A formula allowance is calculated separately for obligors with smallbalance, homogenous loans and for each credit rating category ofcorporate obligors by multiplying the loan balance with the applicable
default ratio (based on internal historical data as well as data provided
by third-party credit rating agencies) and the applicable average
impairment ratio on defaulted loans (based on internal historicaldata).
96

Special attention obligors . . . . . . . . . . . . The allowance for special attention obligors is generally calculated
individually based on the present value of expected future cash flows
discounted at the loan’s initial effective interest rate. A formula
allowance for certain special attention obligors is calculated bygrouping the loans to such obligors and applying the formula
described above for normal and watch obligors but using the default
ratio and average impairment ratio specific to this category.
Intensive control obligors . . . . . . . . . . . . The allowance for intensive control obligors is generally calculated
individually based on the present value of expected future cash flows
discounted at the loan’s initial effective interest rate, based on the
loan’s observable market price, or based on the fair value of thecollateral if the loan is collateral dependent. The allowance for certain
intensive control obligors is calculated by grouping the loans to suchobligors and multiplying the amount of loans less estimated collateralvalue by the default ratio and average impairment ratio specific to thiscategory.
Substantially bankrupt and bankrupt
obligors . . . . . . . . . . . . . . . . . . . . . . . . The allowance is calculated individually and is equal to loan balance,
less estimated collateral value.

Allowance for loan losses increased by ¥10 billion from the end of the previous fiscal year to ¥880 billion asof March 31, 2010. This increase was due to an increase of ¥15 billion in the allowance for loan losses on otherloans, primarily as a result of increased estimated loss rates related to normal obligors, offset in part by adecrease of ¥5 billion in the allowance for loan losses on impaired loans. As a result, the percentage of total
allowance for loan losses against gross total loans increased by 0.2% to 1.4%, and the percentage of allowance
for loan losses on impaired loans against the balance of impaired loans requiring an allowance increased by 0.9%
to 39.3%.

Available-for-sale securities increased by ¥10,246 billion from the end of the previous fiscal year to ¥37,801
billion at March 31, 2010. This increase was due primarily to an increase in medium- to long-term Japanese
government bonds with relatively shorter remaining periods to maturity for the purpose of earning interest
income. Equity securities increased by ¥414 billion from March 31, 2009 to ¥3,284 billion at March 31, 2010 due
mainly to the recovery in Japanese stock prices as of March 31, 2010 compared to March 31, 2009, while thoseon an amortized cost basis decreased as we sold a portion of our equity portfolio in our efforts to reduce the risks
involved in holding stocks. See note 5 to our consolidated financial statements included elsewhere in this annual
report for details of other investments included within investments.
Cash and Due from Banks
Cash and due from banks increased by ¥666 billion from the end of the previous fiscal year to ¥3,399 billion
at March 31, 2010. The increase was due to net cash provided by financing activities of ¥4,105 billion being
offset in part by net cash used in investing activities of ¥2,424 billion and net cash used in operating activities of¥1,014 billion.

Total liabilities increased by ¥973 billion from the end of the previous fiscal year to ¥155,019 billion atMarch 31, 2010. This increase was due primarily to an increase of ¥5,121 billion in short-term borrowings, offset
in part by a decrease of ¥2,106 billion in trading account liabilities and a decrease of ¥1,413 billion in otherliabilities, primarily accounts payable to brokers, dealers and customers for securities transactions. Short-termborrowings include due to trust accounts, call money and funds purchased, payables under repurchaseagreements, payables under securities lending transactions, commercial paper and other short-term borrowings.

Non-interest-bearing deposits, mainly from Japanese companies, decreased by ¥742 billion due primarily to a
decline in the amounts that corporations secured for fiscal-year-end funding, and interest-bearing deposits,
100mainly from individuals, increased by ¥22 billion. Foreign deposits increased by ¥420 billion from the end of theprevious fiscal year to ¥8,538 billion due mainly to an increase in interest-bearing deposits affected by the goodand stable market conditions overseas offset in part by the impact of the appreciation of the yen.
Debentures
Debentures decreased by ¥782 billion from the end of the previous fiscal year to ¥1,518 billion at March 31,
2010. In Japan, certain banks are entitled to issue discount and coupon debentures in the domestic market underapplicable banking laws. Mizuho Corporate Bank and Mizuho Bank benefit from such entitlement originally heldby The Industrial Bank of Japan, one of our predecessor banks. While the two bank subsidiaries have thisentitlement through March 2012, we have been reducing our reliance on debentures in recent years and areshifting to other sources of financing, including mainly bonds.

Equity increased by ¥2,295 billion from the end of the previous fiscal year to ¥3,332 billion due mainly to adecrease in accumulated deficit, increase in common stock and the change from accumulated othercomprehensive loss, net of tax to accumulated other comprehensive income, net of tax, offset in part by adecrease in preferred stock.
Accumulated deficit decreased by ¥969 billion from the end of the previous fiscal year to ¥2,325 billion.
This decrease was due primarily to net income attributable to MHFG shareholders for the fiscal year ended
March 31, 2010 of ¥1,000 billion, offset in part by dividend payments of ¥131 billion.
Common stock increased by ¥937 billion from the end of the previous fiscal year to ¥4,324 billion atMarch 31, 2010 as a result of the issuance of new shares of common stock through a global offering and throughthe conversion of preferred stock. See “—Overview—Capital Improvements.”
Accumulated other comprehensive income (loss), net of tax, improved by ¥626 billion from the end of theprevious fiscal year to income of ¥436 billion at March 31, 2010 due primarily to an increase in unrealized net
gains on available-for-sale securities of ¥506 billion and a decrease in pension liability adjustments of¥203 billion.
Preferred stock decreased by ¥413 billion from the end of the previous fiscal year to ¥536 billion atMarch 31, 2010 as a result of the conversion of preferred stock to common stock.
Treasury stock, at cost, decreased by ¥1 billion from ¥6 billion at the end of the previous fiscal year to¥5 billion at March 31, 2010 due primarily to reissuances from treasury stock related to stock-based
compensation.
Noncontrolling interests increased by ¥175 billion from the end of the previous fiscal year to ¥366 billion atMarch 31, 2010 due primarily to the effect of the business combination of Mizuho Securities and Shinko
Securities. See note 3 to our consolidated financial statements included elsewhere in this annual report for detailsof the business combination.
Liquidity
We continuously endeavor to enhance the management of our liquidity profile and strengthen our capitalbase to meet our customers’ loan requirements and deposit withdrawals and respond to unforeseen situations
such as adverse movements in stock, foreign currency, interest rate and other markets or changes in generaldomestic or international conditions.
Deposits and debentures, based on our broad customer base and brand recognition in Japan, have been our
primary sources of liquidity. Our total deposits and debentures decreased by ¥1,082 billion, or 1.2%, from theend of the previous fiscal year to ¥88,294 billion as of March 31, 2010. As shown in the following table, ouraverage balance of deposits and debentures combined for the fiscal year ended March 31, 2010 exceeded our
average balance of loans for the same period by ¥19,742 billion. We invested the excess portion primarily inmarketable securities and other high liquidity assets.

We will no longer be able to issue debentures beginning April 2012 due to applicable regulations. Mizuho
Corporate Bank ceased issuing debentures, which were issued mainly to institutional investors, in April 2006 andstarted to issue senior straight bonds each quarter. We also ceased all new issuances of debentures by Mizuho
Bank through its retail branch network in April 2007. The balance of our debentures has been decreasing
significantly in recent years as a result.

Secondary sources of liquidity include short-term borrowings such as call money and funds purchased andpayables under repurchase agreement. We also issue long-term debt, including both senior and subordinated debt,
as additional sources for liquidity. We utilize short-term borrowings to diversify our funding sources and to
manage our funding costs. We raise subordinated long-term debt mainly for purposes of enhancing our capital
adequacy ratios. We believe we are able to access such sources of liquidity on a stable and flexible basis based on
our current credit ratings. The following table shows credit ratings assigned to our principal banking subsidiaries
by S&P and Moody’s as of June 30, 2010:

We source our funding in foreign currencies primarily from foreign governments, financial institutions andinstitutional investors, through short-term and long-term financing, under terms and pricing commensurate withour credit ratings above. In the event of future declines in our credit quality or that of Japan in general, we expect
to be able to purchase foreign currencies in sufficient amounts using the yen funds raised through our domestic
customer base. As further measures to support our foreign currency liquidity, we hold foreign debt securities,
maintain credit lines and swap facilities denominated in foreign currencies and pledge collateral to the U.S.
Federal Reserve Bank to support future credit extensions.
We maintain management and control systems to support our ability to access liquidity on a stable and costeffective basis. For a description of our management of liquidity risk, see “Item 11. Quantitative and Qualitative
Disclosures about Market Risk—Market and Liquidity Risk Management.”
Capital Adequacy
All yen figures and percentages in this subsection are truncated. Accordingly, the total of each column offigures may not be equal to the total of the individual items.
Regulatory Capital Requirements
Mizuho Financial Group and its principal banking subsidiaries are subject to regulatory capital requirements
administered by the FSA in accordance with the provisions of the Banking Law and related regulations. Failure
to meet minimum capital requirements may initiate certain mandatory actions by regulators that, if undertaken,
could have a direct material effect on our consolidated financial statements.
The capital adequacy guidelines applicable to Japanese banks and bank holding companies withinternational operations supervised by the FSA closely follow the risk-adjusted approach proposed by the Bankfor International Settlements (“BIS”) and are intended to further strengthen the soundness and stability ofJapanese banks. Effective March 31, 2007, new guidelines were implemented by the FSA to comply with the
new capital adequacy requirements set by BIS called Basel II. The framework of Basel II is based on thefollowing three pillars: minimum capital requirements; supervisory review; and market discipline.
Under the first pillar, the capital ratio is calculated by dividing regulatory capital by risk-weighted assets.
With respect to the calculation of risk-weighted assets, Mizuho Financial Group adopted the advanced internalratings-based approach (“AIRB approach”) instead of the foundation internal ratings-based approach (“FIRB
approach”) in the fiscal year ended March 31, 2009. Under the AIRB approach, balance sheet assets and103

off-balance sheet exposures, calculated under Japanese GAAP, are assessed in terms of credit risk according torisk components such as the probability of default and loss given default, which are derived from our own
internal credit experience. Under the FIRB approach, only the probability of default was derived by our own
internal credit experience. In addition to credit risk, banks are required to measure and apply capital charges withrespect to their market risks. Market risk is defined as the risk of losses in on- and off-balance-sheet positions
arising from movements in market prices. Operational risk, which was introduced under Basel II with respect toregulatory capital requirements, is the risk of loss resulting from inadequate or failed internal processes, people
and systems or from external events. Mizuho Financial Group adopted the advanced measurement approach(“AMA”) instead of the standardized approach (“TSA”) as of September 30, 2009 for the measurement ofoperational risk equivalent by taking account of the following four elements: internal loss data; external loss data;
scenario analysis; and business environment and internal control factors (“BEICFs”).
With regard to risk-based capital, these guidelines are consistent with the original BIS framework, orBasel I, in requiring a target minimum standard capital adequacy ratio of 8%, at least half of which must consistof Tier 1 capital, on both a consolidated and non-consolidated basis for banks with international operations, suchas Mizuho Corporate Bank and Mizuho Trust & Banking, or on a consolidated basis for bank holding companies
with international operations, such as Mizuho Financial Group.
Risk-based capital, calculated from financial statements prepared under Japanese GAAP, is classified into
the following three tiers: Tier 1 capital; Tier 2 capital; and Tier 3 capital. Tier 1 capital generally consists ofshareholders’ equity less any recorded goodwill, unrealized losses on other securities (net of taxes) (if any),
consolidation adjustment accounts and others. Tier 2 capital generally consists of the following components:•

general reserve for possible losses on loans, equaling the sum of (i) the excess of the amount of qualified
reserves over the amount of expected losses and (ii) the amount of general reserves calculated based on
the TSA;•

45% of each of the unrealized gains on valuation of certain securities classified as “other securities”
under Japanese GAAP, if any, and the unrealized appreciation in the value of land;•

the balance of subordinated perpetual debt; and•the balance of subordinated term debt with an original maturity of over five years and preferred termshares up to 50% of Tier 1 capital.

Tier 2 capital may be included in a bank’s risk-based capital up to the amount equivalent to Tier 1 capital,
less Tier 3 capital if market risk is taken into account in the capital adequacy ratio calculation. Tier 3 capitalconsists of the balance of subordinated term debt with original maturity of at least two years. Tier 3 capital may
be included in total risk-based capital subject to certain conditions, depending on the measure for market risk
equivalent and the amount of Tier 1 capital.
Japanese banks are also required to comply with the supervisory review process (second pillar) anddisclosure requirements for market discipline (third pillar). Under the second pillar, banks are required tomaintain adequate capital to support all of the major risks in their business and are encouraged to develop anduse better risk management techniques in monitoring and managing such risks. Under the third pillar, banks are
required to enhance disclosure, including disclosure of details of the capital adequacy ratio, the amount of eachtype of risk and the method of calculation used so that the market may make more effective evaluations.
Japanese banks with only domestic operations, such as Mizuho Bank, are subject to Japanese capital
adequacy requirements that are similar to those discussed above, except that domestic banks are required tomaintain a minimum capital adequacy ratio of 4%, at least half of which must consist of Tier 1 capital, on both aconsolidated and non-consolidated basis.
In December 2008, the FSA implemented special temporary measures, applicable through March 2012,
which (i) allow Japanese banks and bank holding companies with international operations to elect not to add
104unrealized gains on valuation of bonds with a zero risk weighting to Tier 2 capital and not to deduct unrealized
losses on valuation of bonds with a zero risk weighting from Tier 1 capital, and (ii) require Japanese banks andbank holding companies with only domestic operations not to deduct unrealized losses on valuation of “othersecurities” under Japanese GAAP (including equity securities) from Tier 1 capital. The Japanese capital
adequacy requirements applicable to Japanese banks and bank holding companies with only domestic operations
do not allow unrealized gains on “other securities” to be added to Tier 2 capital before or after this special
temporary measures.
If the capital adequacy ratio of a financial institution falls below the required level, the FSA may, depending
upon the extent of capital deterioration, take certain corrective action, including requiring the financial institution
to submit an improvement plan to strengthen its capital base, reduce its total assets, restrict its business
operations or other actions that could have a material effect on its financial statements.
In the wake of the recent global financial crisis, in July 2009, the Basel Committee approved a package ofmeasures to strengthen the rules governing trading book capital and enhance the Basel II framework, including
an introduction of higher capital requirements to capture the credit risk of complex trading activities andresecuritization exposures, which will take effect at the end of 2010. Further, in December 2009, the BaselCommittee issued a consultative document entitled “Strengthening the resilience of the banking sector” that
contains a package of proposals on measures to strengthen global bank capital. The Basel Committee’s proposals
focus on raising the quality, consistency and transparency of the regulatory capital base through measures
including the application of the following requirements:•

the predominant form of Tier 1 capital must be common shares and retained earnings;•

the remainder of the Tier 1 capital base must be comprised of instruments that are subordinated, havefully discretionary noncumulative dividends or coupons and have neither a maturity date nor an
incentive to redeem;•

regulatory adjustments, including deductions of the amount of net deferred tax assets which rely on the
future profitability, are to be applied to the common equity generally; and•an additional disclosure requirement regarding regulatory capital levels.

The proposals of the Basel Committee also focus on strengthening the capital requirements for counterparty
credit risk exposures arising from derivatives, repos and securities financing activities and introduce measures tomitigate excessive reliance on external ratings. Other areas of focus include the following:•

introduction of an internationally harmonized leverage ratio as a supplementary measure to the Basel II
risk-based framework;•

proposal of a framework for countercyclical capital buffers established above the regulatory minimum
capital requirements, including constraints on distributions such as ordinary dividends and sharebuybacks;•

promotion of more forward-looking provisioning based on expected losses; and•measures to address the systemic risk arising from the interconnectedness of banks and other financial
institutions.

At the same time, the Basel Committee published a consultative document containing proposals on the
introduction of a global minimum liquidity standard for internationally active banks that includes a 30-day
liquidity coverage ratio requirement underpinned by a longer-term structural liquidity ratio.
The proposals contained in the two consultative documents are subject to further discussion of details. The
Basel Committee is carrying out a comprehensive impact assessment of the proposed standards and plans todevelop by the end of 2010 a fully calibrated set of standards, including minimum requirements for the overall
105

level of capital, Tier 1 capital and the predominant form of Tier 1 capital, to be phased in as financial conditions
improve and the economic recovery is assured, with the aim of implementation by the end of 2012. The BaselCommittee also stated that it will consider appropriate phase-in measures and grandfathering arrangements for a
sufficiently long period to ensure a smooth transition to the new standards. Once the new standards are adopted,
the Japanese capital ratio framework, which is based on Basel II, is likely to be revised to implement the more
stringent requirements in accordance with the new standards. While closely monitoring the ongoing global
discussions with respect to capital, we will take various measures in anticipation of the revision of capital
regulations to be globally agreed.

Our capital adequacy ratio as of March 31, 2010 was 13.46%. Our Tier 1 capital ratio as of March 31, 2010
was 9.09%, which significantly improved from March 31, 2009 due to an increase in Tier 1 capital as well as adecrease in our risk-weighted assets. Tier 1 capital increased as a result of the issuance of common stock in Julyand August 2009, the absence of unrealized losses on other securities, the effect of the merger between theformer Shinko Securities and the former Mizuho Securities, issuance of non-dilutive preferred securities throughoverseas special purpose companies and increase in retained earnings as a result of recording net income for the
fiscal year ended March 31, 2010, which was offset in part by redemption of non-dilutive preferred securities
issued through overseas special purpose companies. Risk-weighted assets decreased by ¥2,192.9 billion to¥56,863.2 billion as of the end of the fiscal year ended March 31, 2010 due mainly to a decrease in balance ofloans to large Japanese corporations and overseas borrowers. We believe that we were in compliance with all
capital adequacy requirements to which we were subject as of March 31, 2010.

Our Tier 1 capital increased by ¥1,408.4 billion from ¥3,765.0 billion as of March 31, 2009 to ¥5,173.4
billion as of March 31, 2010. This increase was due mainly to the issuance of common stock of ¥529.2 billion,
the absence of unrealized losses on other securities of ¥516.0 billion, the effect of the merger between the former
Shinko Securities and the former Mizuho Securities, issuance of non-dilutive preferred securities throughoverseas special purpose companies and an increase in retained earnings as a result of recording net income of¥239.4 billion for the fiscal year ended March 31, 2010, which was offset in part by redemption of non-dilutive
preferred securities issued through overseas special purpose companies.
Minority interest in consolidated subsidiaries included within our Tier 1 capital includes non-dilutive
preferred securities issued by our overseas special purpose companies to investors. As of March 31, 2010, theamount of minority interest in consolidated subsidiaries within our Tier 1 capital that was attributable to suchnon-dilutive preferred securities was ¥1,937.8 billion. Although such non-dilutive preferred securities areperpetual in term, they are redeemable at our option, subject to prior approval from regulatory authorities, on,
and on specified dates after, the relevant initial optional redemption date. The following table shows the initial
optional redemption dates for the non-dilutive preferred securities included within our Tier 1 capital as ofMarch 31, 2010 and the total amount of non-dilutive preferred securities with each such initial optional

Notes:(1) Preferred stock as of March 31, 2006 includes public funds, or preferred stock we issued to the Resolution
and Collection Corporation, in the amount of ¥600.0 billion. We completed repayment of all public funds inJuly 2006.
(2) Excludes treasury stock.
(3) Tier 1 capital on a Basel I basis was used for March 31, 2006 figures, and that on a Basel II basis was used
for March 31, 2007, 2008, 2009 and 2010 figures.
(4) During the period from April 1, 2010 to June 30, 2010, holders of our eleventh series class XI preferredstock converted 6,500,000 shares (or ¥ 6.5 billion) by requesting us to acquire the preferred stock and issuecommon stock to them.
In relation to the components of Tier 1 capital, changes to the definition of capital such as the predominant
form of Tier 1 are proposed in the consultative document issued by the Basel Committee in December 2009. See“—Capital Adequacy—Regulatory Capital Requirements.”
Our Tier 2 capital included as qualifying capital as of March 31, 2010 was ¥2,725.4 billion, a decrease of¥67.7 billion compared to March 31, 2009. The decrease was due mainly to the decreases in debt capital.
As a result of the above, together with deductions of ¥240.8 billion, total risk-based capital as ofMarch 31, 2010 was ¥7,658.0 billion, an increase of ¥1,434.3 billion compared to March 31, 2009.
Prime Capital
Alongside the regulatory capital requirements supervised by the FSA, we calculate and monitor“prime capital” as our important management indicator. Prime capital represents capital items with a stronger
ability to absorb losses. Prime capital is calculated as Tier 1 capital less the sum of the preferred securities andpreferred stock (excluding mandatory convertible preferred stock), and prime capital ratio is the ratio of prime
capital against risk-weighted assets. We aim to increase our prime capital ratio to 8% or above, as calculated
under current Basel II rules, by the end of the fiscal year ending March 31, 2013. The foregoing statements
constitute forward-looking statements and are subject to risks, uncertainties and assumptions. See “Forwardlooking Statements” and “Item 3.D. Key Information—Risk Factors.”
Prime capital differs in certain significant respects from the predominant form of Tier 1 capital as proposedin the consultative document issued by the Basel Committee in December 2009.

Risk-weighted assets as of March 31, 2010 were ¥56,863.2 billion, representing a decrease of ¥2,192.9
billion compared to March 31, 2009. Credit risk assets decreased by ¥2,322.9 billion to ¥51,908.7 billion due
mainly to a decrease in balance of loans to large Japanese corporations and overseas borrowers. Market risk
equivalent assets decreased by ¥44.2 billion to ¥1,297.9 billion. Operational risk equivalent assets increased by¥174.1 billion to ¥3,656.5 billion due mainly to the merger between the former Shinko Securities and the former
Mizuho Securities offset in part by the effect of application of AMA instead of TSA.

Note:
(1) BIS standards apply only to banks with international operations. Because Mizuho Bank does not operate
overseas, it is subject solely to domestic capital adequacy requirements. As such, information based on the
BIS standards is included for reference purpose only.
We believe each of our principal banking subsidiaries was in compliance with all capital adequacy
requirements to which it was subject as of March 31, 2010.
Our securities subsidiaries in Japan are also subject to the capital adequacy requirement under the Financial
Instruments and Exchange Law. Under this requirement, securities firms must maintain a minimum capital
adequacy ratio of 120% calculated on a non-consolidated basis as a percentage of capital accounts less certain
assets, as determined in accordance with Japanese GAAP, against amounts equivalent to market, counterparty
and basic risks. Specific guidelines are issued as a ministerial ordinance that details the definition of essential
components of the capital ratios, including capital, disallowed assets and risks, and related measures. Failure to
maintain a minimum capital ratio will trigger mandatory regulatory actions. A capital ratio of less than 140% willcall for regulatory reporting and a capital ratio of 100% or less may lead to a temporary suspension of all or partof the business operations and cancellation of the license to act as a securities broker and dealer. Further, on
May 19, 2010, certain amendments to the Financial Instruments and Exchange Law were promulgated, including
introduction of a minimum capital adequacy regulation on a consolidated basis applicable to securities firms
whose total assets exceed certain threshold. The amendments relevant to such regulation will become effectiveby May 2011. We believe, as of March 31, 2010, that our securities subsidiaries in Japan are in compliance withall capital adequacy requirements to which they are subject.

110Off-balance-sheet Arrangements
We engage in various types of off-balance-sheet arrangements in the ordinary course of our business to meetthe financing needs of our customers. These arrangements include various guarantees and commitments. The
following tables show the contractual or notional amounts of our guarantees and undrawn commitments as ofMarch 31, 2009 and 2010:

See note 25 to our consolidated financial statements included elsewhere in this annual report for a
description of the nature of the various types of guarantees and commitments.
The contractual or notional amounts of these instruments generally represent the maximum potential
amounts of future payments without consideration of possible recoveries under recourse provisions or fromcollateral held. For example, the amount under commitments to extend credit does not necessarily equal theimpact that such commitment will have on our future cash flow, because many of these commitments expire
without our making actual credit extensions up to the full commitment amount or at all. Also, many of theagreements related to the commitments to extend credit include terms that allow us to refuse, or reduce theamount of, credit extensions based on changes in the financial environment, declines in the obligor’s credit
quality and other reasons. Finally, we receive collateral such as real estate and securities at the time of contract as
we deem necessary, and we regularly review the credit quality of the customer based on internal guidelines andrevise the terms of the contract as we deem necessary to manage credit risk.
Some of our off-balance-sheet arrangements are related to activities of special purpose entities, most ofwhich are variable interest entities, including those that do not meet the consolidation requirements under ASC
810 “Consolidation.” These off-balance-sheet arrangements include the types of transactions discussed below.
Asset-backed Commercial Paper/Loan Programs
We manage several asset-backed commercial paper/loan programs that provide our clients’ off-balancesheet and cost-effective financing. The variable interest entities used in the programs purchase assets, primarily
receivables, from clients participating in the programs and provide liquidity through the issuance of commercial
paper or borrowings from us backed by the assets. While customers normally continue to service the transferred
receivables, we underwrite, distribute and make a market in commercial paper issued by the variable interest
111

entities. We typically provide program-wide liquidity and credit support facilities and, in some instances,financing to the variable interest entities. We determined that we absorb a majority of expected losses or
expected residual returns through the facilities and, therefore, consolidated this type of variable interest entities.
Asset-backed Securitizations
We act as an arranger of various types of structured finance to meet clients’ various off-balance-sheet
financing needs. In substantially all of these structured financing transactions, the transfer of the asset by theclient is structured to be bankruptcy remote by use of a bankruptcy remote entity, which is deemed to be avariable interest entity because its equity holder does not have decision-making rights. We receive fees forstructuring and/or distributing the securities sold to investors. In some cases, we ourselves purchase the securities
issued by the entities and/or provide loans to the variable interest entities.
In addition, from time to time we establish single-issue and multi-issue special purpose entities that issue
collateralized debt obligations or collateralized loan obligations, synthetic collateralized debt obligations orcollateralized loan obligations or other repackaged instruments to meet clients’ and investors’ needs. We also
arrange securitization transactions including commercial mortgage-backed securities and residential mortgagebacked securities mainly in Japan and others. In these transactions, we act as an underwriter, placement agent,asset manager, derivatives counterparty and/or investor for debt and equity instruments.
In certain variable interest entities, where we provide liquidity and credit support facilities, write credit
protection or invest in debt or equity instruments, we determined that we absorb a majority of expected losses or
expected residual returns and, therefore, consolidated the variable interest entities.
Investments in Securitization Products
We invest in, among other things, various types of collateralized debt obligations and collateralized loan
obligations, synthetic collateralized debt obligations and collateralized loan obligations and repackaged
instruments, commercial mortgage-backed securities and residential mortgage-backed securities arranged bythird parties for the purpose of current income or capital appreciations, which all utilize entities that are deemedvariable interest entities.
By design, such investments were investment grade at issuance and held by a diverse group of investors. We
usually take into consideration the seniority and the share of our investments by each tranche to evaluate whether
we are the primary beneficiary. The loss amount of securities and loans is generally limited to the amountinvested because we have no contractual involvement in such variable interest entities beyond our investments.
However, we consolidated some variable interest entities, mostly where the transactions were tailored by thethird party arrangers to meet our needs as a sole investor.
Investment Funds
We invest in various investment funds, including securities investment trusts that invest in equity and debt
securities such as listed Japanese securities and investment grade bonds. Investment advisory companies or fundmanagement companies, including our subsidiaries and affiliates, administer and make the investment decisions
with respect to such investment funds. We consolidate certain investment funds where we are deemed to be theprimary beneficiary.
Trust Arrangements
We offer a variety of asset management and administration services under trust arrangements, including
security investment trusts, pension trusts and trusts used in the securitization of assets originated by andtransferred to third parties. We receive trust fees for providing services as an agent or fiduciary on behalf ofbeneficiaries.
112

With respect to guaranteed principal money trust products, we assume certain risks by providing guarantees
for the repayment of principal as required by the trust agreements or relevant Japanese legislation. We manage
entrusted funds primarily through the origination of high-quality loans and other credit-related products,
investing in high-grade marketable securities such as Japanese government bonds and placing cash with our
subsidiary trust banks to maintain liquidity and for cash management purposes. We have determined throughexpected loss calculation that we do not absorb a majority of the expected losses or expected residual returns inconnection with these trust arrangements but had significant variable interests and, therefore, the trust accounts
are not included in our consolidated financial statements but are disclosed in the tables below regarding
significant or sponsored unconsolidated VIEs.

Asset-backed commercial paper/loan programs include multi-seller programs managed by us, under which
the related conduits purchase various types of assets from our clients, consisting mainly of account and note
receivables as well as credit card receivables, auto loans, leases and other receivables. Our involvement with
conduits for multi-seller programs is generally more significant than other types of conduits in terms of liquidity
support and credit enhancement obligations. All of the conduits for our asset-backed commercial paper/loan
programs to which we provided liquidity support or credit enhancements were consolidated VIEs as of March 31,
2010. See “—Overview—Our Special Purpose Entities—Variable Interest Entities (VIEs)” for more informationon our VIEs.
Other Types of Off-balance-sheet Arrangements

Recent Accounting Pronouncements
Accounting pronouncements issued but not yet effective
In June 2007, the American Institute of Certified Public Accountants (“AICPA”) issued Statement of
Position (“SOP”) No.07-1, “Clarification of the Scope of the Audit and Accounting Guide Investment
Companies and Accounting by Parent Companies and Equity Method Investors for Investments in Investment
Companies,” which is now included in ASC 946, “Financial Services—Investment Companies” (“ASC 946”),and provides guidance for determining whether an entity is within the scope of the AICPA Audit and Accounting
Guide Investment Companies (“the Guide”). The statement was expected to be effective for fiscal years
beginning on or after December 15, 2007, with earlier application encouraged. However, in February 2008, the
FASB issued FSP No.SOP07-1-1, “Effective Date of AICPA Statement of Position 07-1,” which is now included
in ASC 946 as well, to delay the effective date of SOP No.07-1 indefinitely in order to address implementation
issues. We dos not expect that the current form of the statement will have a material impact on our consolidated
results of operations or financial condition.
In June 2009, the FASB issued SFAS No.166, “Accounting for Transfers of Financial Assets—anamendment of FASB Statement No.140,” which is now included in ASC 860. The statement requires more
information about transfers of financial assets, including securitization transactions, where enterprises havecontinuing exposure to the risks related to the transferred financial assets. The statement eliminates the conceptof qualifying SPE and modifies the requirements for derecognizing financial assets. The statement is effective asof the beginning of the first fiscal year that begins after November 15, 2009. Early adoption is prohibited.
In June 2009, the FASB issued SFAS No.167, “Amendments to FASB Interpretation No.46(R),” which is
now included in ASC 810. The statement provides a new guidance how an enterprise determines whether theenterprise’s variable interests give it a controlling financial interest in VIEs. The determination is based on,among other things, VIE’s purpose and design, an enterprise’s ability to direct the activities of the VIE that mostsignificantly impact the entity’s economic performance, and if an enterprise has the obligation to absorb losses ofor the right to receive benefits from the VIE that could be significant. The statement is effective as of the
beginning of the first fiscal year that begins after November 15, 2009. Early adoption is prohibited. In February
2010, the FASB issued ASU No.2010-10, “Consolidation (Topic 810)—Amendments for Certain Investment
Funds” (“ASU No.2010-10”). The ASU provides that the consolidation requirements of SFAS No.167 aredeferred for an entity that has all the attributes of an investment company (or similar entity). On April 1, 2010,
we adopted SFAS No.167, together with SFAS No.166, which primarily resulted in the consolidation of certain
former qualifying SPEs, guaranteed principal money trust products and collateral loan obligations (“CLO”)
where we act as an asset manager. The impact of adoption of SFAS No.166 and SFAS No.167 was a net increasein assets of approximately ¥460 billion, with no material impact on equity as of April 1, 2010.
114

In January 2010, the FASB issued ASU No.2010-06, “Fair Value Measurements and Disclosures (Topic820)—Improving Disclosures about Fair Value Measurements” (“ASU No.2010-06”). The ASU provides
amendments to ASC 820-10 that require new disclosures regarding (1) transfers in and out of Levels 1 and 2 and(2) more detailed activity in Level 3. The ASU also provides amendments to ASC 820-10 that clarify existing
disclosures regarding (1) level of disaggregation and (2) inputs and valuation techniques. The ASU is effective
for interim and annual reporting periods beginning after December 15, 2009, except for the new disclosuresrelated to the activity in Level 3, which do not become effective until fiscal years beginning after December 15,
2010, and for interim periods within those fiscal years. ASU No.2010-06 is an accounting principle which
expands disclosure requirements, and has no impact on our consolidated results of operations or financial
condition.
In March 2010, the FASB issued ASU No.2010-11, “Derivatives and Hedging (Topic 815)—Scope
Exception Related to Embedded Credit Derivatives” (“ASU No.2010-11”). The ASU clarifies the scope
exception for embedded credit derivative features related to the transfer of credit risk, which are subject topotential bifurcation, and indicate circumstances which do not qualify for the scope exception. The ASU is
effective at the beginning of the first fiscal quarter beginning after June 15, 2010. Early adoption is permitted.
We are currently evaluating the potential impact that the adoption of ASU No.2010-11 will have on ourconsolidated results of operations and financial condition.
In July 2010, the FASB issued ASU No.2010-20, “Receivables (Topic 310)—Disclosures about the Credit
Quality of Financing Receivables and the Allowance for Credit Losses” (“ASU No.2010-20”). The ASU requires
disclosures that facilitate financial statement users’ evaluation of (1) the nature of credit risk inherent in theentity’s portfolio of financing receivables, (2) how that risk is analyzed and assessed in arriving at the allowancefor credit losses, and (3) the changes and reasons for those changes in the allowance for credit losses. The new
disclosures required include (1) aging of past due receivables, (2) credit quality indicators, and (3) modificationsof financing receivables. It is also required that the certain existing disclosures should be provided on adisaggregated basis. The disclosures as of the end of a reporting period are effective for interim and annual
reporting periods ending on or after December 15, 2010, whereas the disclosures about activity that occurs during
a reporting period are effective for interim and annual reporting periods beginning on or after December 15,
2010. ASU No.2010-20 is an accounting principle which expands disclosure requirements, and has no impact on
our consolidated results of operations or financial condition.

Reconciliation with Japanese GAAP
Our consolidated financial statements are prepared in accordance with accounting principles and policies assummarized in note 1 to our consolidated financial statements included elsewhere in this annual report. These
principles and policies differ in some respects from Japanese GAAP. Under Japanese banking regulations, we are
required to report our annual financial results using financial statements prepared under Japanese GAAP. In
addition, pursuant to the requirements of the Tokyo Stock Exchange, we prepare quarterly financial statements
which are also under Japanese GAAP. To show the major reconciling items between our U.S. GAAP financial
statements and our Japanese GAAP financial statements, we have provided below, with respect to our mostrecent fiscal year, a reconciliation of consolidated net income and shareholders’ equity under U.S. GAAP withthose amounts under Japanese GAAP.

¥3,515.4¥ 239.4

The following is a summary of the significant adjustments made to consolidated shareholders’ equity andnet income, as shown in the above table, to reconcile the U.S. GAAP results with Japanese GAAP. The
paragraphs below refer to the corresponding items set forth in the table above.
1.

Derivative financial instruments and hedging activities

Under U.S. GAAP, for a derivative to qualify for hedge accounting, it must be highly effective at achieving
offsetting changes in fair values or variable cash flows from the hedged items attributable to the particular risk
being hedged. The hedging relationship must be designated and formally documented at inception. Suchdocumentation must include the particular risk management objective and strategy for the hedge, theidentification of the derivative used as the hedging instrument, the hedged item and the risk exposure being
hedged and the method for assessing the hedge effectiveness. The criteria for designation and measurement ofhedge effectiveness under U.S. GAAP are more rigorous than under Japanese GAAP. As a result, most of theeligible hedge derivatives under Japanese GAAP are accounted for as trading account assets or liabilities under
U.S. GAAP with changes in fair value of the derivatives recognized in earnings.

116Requirements for bifurcation of embedded derivatives differ between Japanese GAAP and U.S. GAAP.
Embedded derivatives that are deemed to be clearly and closely related to their host contract are not bifurcatedunder U.S. GAAP, while Japanese GAAP allows an entity to bifurcate embedded derivatives if the entity
manages the risk of the embedded derivatives and host contracts separately. Bifurcated derivatives are recordedon the balance sheet at fair value with changes in fair value recognized in earnings under both Japanese GAAP
and U.S. GAAP.
2.

Investments

The cost basis of certain investments differs between Japanese GAAP and U.S. GAAP primarily due to thefollowing reasons:Certain sales and subsequent repurchases of available-for-sale securities under Japanese GAAP do not meetthe sale accounting criteria under U.S. GAAP. These sales and subsequent repurchases resulted in realized gains
or losses being recognized in earnings under Japanese GAAP. Under U.S. GAAP, these gains or losses arerecognized as unrealized gains or losses within accumulated other comprehensive income, net of tax.
Under U.S. GAAP, declines in the fair value of available-for-sale securities below cost that are deemed tobe “other-than-temporary” are recorded in earnings. Both quantitative and qualitative factors are considered todetermine whether the impairment is “other-than-temporary,” including the duration and extent of the decline,
near-term prospects of the issuer, as well as our ability and intent to hold the investments until an anticipatedmarket price recovery or maturity. Under Japanese GAAP, significant declines in the fair value of securities
below cost that are deemed to be “other-than-temporary” are recorded in earnings unless short term recovery isreasonably expected. A decline in fair value of a security of 50% or more of its cost is a strong indicator of another-than-temporary decline, which requires compelling evidence to prove otherwise. A decline in fair value of
30% or more but less than 50% of its cost is an indicator of an other-than-temporary decline in which case theprobability of recovery must be evaluated to determine whether an other-than-temporary decline has occurred.
Generally, if the decline in fair value is less than 30%, it is not considered to be an other-than-temporary decline.
Under U.S. GAAP, the election of the fair value option for financial assets and liabilities is permitted
according to ASC 825, while it is not permitted under Japanese GAAP. As we elected the fair value option forforeign currency denominated available-for-sale securities under U.S. GAAP, these securities were reclassified
as trading securities and the entire amount of changes in their fair value are now recognized in earnings, while
under Japanese GAAP, only the changes attributable to movements in foreign currency exchange rates arerecognized in earnings.
Reconciliation amounts for investments in the above table are presented net of taxes.
3.

Loans

Under U.S. GAAP, loan origination fees, net of certain direct origination costs, are deferred and recognized
in interest income over the contractual life of the relevant loan using the interest method, while under Japanese
GAAP, fees and costs are recognized in earnings at the time the loan is originated.
In addition, certain loan participations and sales of loans to special purpose vehicles in connection with asset
securitization transactions under Japanese GAAP do not meet sales criteria under U.S. GAAP due to different
applicable criteria, and therefore the relevant loans are recognized on the balance sheet under U.S. GAAP.
4.

Allowances for loan losses and off-balance-sheet instruments

Under both Japanese GAAP and U.S. GAAP, the allowance for loan losses for specifically identified
impaired loans is based on the present value of expected future cash flows discounted at the loan’s initial117effective interest rate or as a practical expedient, the loan’s observable market price or the fair value of thecollateral if the loan is collateral dependent. For certain impaired loans which are aggregated for the purpose ofmeasuring impairment, pools of smaller balance homogeneous loans and other non-homogenous loans that havenot been identified as impaired, the allowance for loan losses is determined based on a formula allowance
utilizing historical loss factors, as adjusted, considering recent trends.
The differences between Japanese GAAP and U.S. GAAP arise from the difference in application of theformula allowance and the scope of the loans that are subject to the individual and portfolio impairment analysis.
In addition to these effects based on differences between Japanese GAAP and U.S. GAAP, provision (credit) forloan losses may differ between Japanese GAAP and U.S. GAAP due to the difference in the timing of accounting
closings between our consolidated financial statements under U.S. GAAP and those under Japanese GAAP.
This reconciling item also includes the differences between U.S. GAAP and Japanese GAAP relating to theallowance for off-balance-sheet instruments. We generally use the same methodology to reserve for losses onthese instruments as we do for loans.
5.

Premises and equipment

Under U.S. GAAP, the fair value of a non-monetary asset acquired in exchange for another non-monetary
asset is generally deemed to be the new cost of the asset acquired in the exchange, and a gain or loss isrecognized on the exchange. Under Japanese GAAP, the cost of the asset surrendered is assigned to the newly
acquired asset in certain types of exchange transactions, resulting in no gains or losses. In addition, the differencein carrying value of assets acquired in a non-monetary exchange results in a difference in the depreciation
schedule between U.S. GAAP and Japanese GAAP.
6.

Real estate sales and leasebacks

Our principal banking subsidiaries entered into sale and leaseback transactions in prior years with respect toland and buildings used as their headquarters. Each sale of such real estate is accounted for as a sale underJapanese GAAP with profits on the sale recorded in earnings. Under U.S. GAAP, the profits are deferred andamortized within the respective lease periods as the subsidiaries continue to occupy the buildings under operatingleases.
7.

Land revaluation

Under Japanese GAAP, we revalued our holdings of land during the fiscal year ended March 31, 1998
pursuant to the Law Concerning Revaluation of Land (Law No. 34 of 1998). The revaluation gains are recorded
directly in equity, and the related deferred tax liabilities are also recognized. Under U.S. GAAP, there is no
applicable provision that allows for the revaluation of land other than for impairments, and accordingly therevaluation gains are reversed.
8.

Business combinations

U.S. GAAP and Japanese GAAP differ with regard to accounting for business combinations, primarily inaccounting for goodwill. Under U.S. GAAP, goodwill is not amortized and an impairment loss is recorded to theextent the carrying amount of the goodwill exceeds its estimated fair value at the measurement date. Under
Japanese GAAP, goodwill is amortized over an appropriate period not to exceed 20 years and an impairment loss
is recorded only if the effects of the goodwill are no longer expected. In the fiscal year ended March 31, 2010,
the merger between former Mizuho Securities and Shinko Securities which consummated in May 2009 affected
net income differently.
9.

Non-interest-bearing deposits made under government-led restructuring program

In connection with the government-led restructuring program for seven failed housing loan companies, wemade non-interest bearing deposits of ¥359,017 million in the fiscal year ended March 31, 1997. Under Japanese118

GAAP, these deposits are recorded at cost. Under U.S. GAAP, these deposits are discounted to their present
value at the time of deposit, and the discount is subsequently accreted to income over the expected period tomaturity.
10.

Pension liabilities

Under Japanese GAAP, we adopted as of April 1, 2000, pension accounting that is based on the actuarial
present value of accrued benefit obligations. The cumulative effect of the accounting change has been amortized
and actuarial gains and losses are deferred and amortized. Under U.S. GAAP, we recalculated the benefit
obligation at April 1, 2004 and accounted for the obligation as if we had adopted the accounting method in
accordance with ASC 715, “Compensation—Retirement Benefits,” beginning in the fiscal year ended March 31,
1990, as permitted for a foreign private issuer. The cumulative effect of the accounting change, as well as
actuarial gains and losses since the adoption, had been fully amortized by April 1, 2004.
Under U.S. GAAP, an employer is required to recognize the overfunded or underfunded status of a defined
benefit plan as an asset or liability in its consolidated balance sheets, according to ASC 715. Under ASC 715,
actuarial gains or losses and prior service costs or benefits that have not yet been recognized through earnings as
net periodic benefit cost are recognized in other comprehensive income, net of tax, until they are amortized as acomponent of net periodic benefit cost based on corridor approach. Under Japanese GAAP, they are notimmediately recognized in the consolidated balance sheets and are instead amortized over a specified number ofyears. This results in a difference in the amount of the shareholders’ equity between U.S. GAAP and Japanese
GAAP. See note 22 to our consolidated financial statements included elsewhere in this annual report for further
discussion.
11.

Consolidation of variable interest entities

Under U.S. GAAP, variable interest entities are to be consolidated if we are deemed to be the primary
beneficiary of the variable interest entity. Under Japanese GAAP, consolidation is not based on variable interests.
We consolidate certain variable interest entities, such as entities related to asset-backed commercial paper/loan
programs, asset-backed securitizations, investments in securitization products and investment funds. See note 27
to our consolidated financial statements included elsewhere in this annual report for further discussion.
12.

Deferred taxes

Under U.S. GAAP, all available evidence, both positive and negative, must be considered to determine
whether, based on the weight of that evidence, deferred tax assets are realizable or whether a valuation allowanceis needed. Possible sources of taxable income, which are considered to determine whether deferred tax assets are
realizable, include unrealized gains on available-for-sale securities. The sources also include tax planning
strategies that are prudent and feasible. Under Japanese GAAP, the assessment as to whether deferred tax assets
are realizable is primarily based on estimates of future taxable income.
Additionally, differences in the carrying amount of assets and liabilities between U.S. GAAP and Japanese
GAAP create temporary differences that result in differences in deferred tax assets and liabilities.

Officers currently in office will expire at the close of the first meeting of our board of directors after the ordinary
general meeting of shareholders.
No family relationship exists among any of our directors, executive officers or corporate auditors.
6.B. Compensation
In accordance with the Company Law, compensation for our directors and corporate auditors, including
bonuses, retirement allowances and incentive stock options, must be approved at our general meeting ofshareholders, unless otherwise specified in our articles of incorporation in the future. The shareholders’ approval
may specify the upper limit of the aggregate amount of compensation or calculation methods, but if
compensation includes benefits in kind, the shareholders’ approval must include the description of such benefits.
Compensation for a director or corporate auditor is fixed by our board of directors or by consultation among ourcorporate auditors in accordance with our internal regulations and practice and, in the case of retirement
allowances, generally reflects the position of the director or corporate auditor at the time of retirement, the lengthof his service as a director or corporate auditor and his contribution to our performance.
The aggregate compensation, including bonuses and stock compensation-type stock options (stockacquisition rights) but excluding retirement allowances, paid by Mizuho Financial Group and its subsidiaries tothe directors and corporate auditors of Mizuho Financial Group during the fiscal year ended March 31, 2010 was¥602 million and ¥79 million, respectively.
Beginning the fiscal year ended on or after March 31, 2010, listed companies in Japan are required under
Cabinet Office Ordinance on Disclosure of Corporate Affairs, etc., to disclose the compensation provided to theirdirectors and corporate auditors for the relevant fiscal year if the aggregate annual compensation per the director/
corporate auditor equals or exceeds ¥100 million (including any compensation provided by major subsidiaries of129such listed company as directors and corporate auditors of such subsidiaries). The following table sets forth

Mizuho Financial Group and some of its subsidiaries, including Mizuho Bank and Mizuho Corporate Bank,

obtained shareholders’ approval for a payment of lump sum retirement allowances for directors and corporate
auditors (other than those elected after such shareholders’ meeting) at the time of their respective retirement.
In conjunction with the abolishment of the retirement allowance program, we obtained shareholder’sapproval for the introduction of stock acquisition rights for the directors (excluding outside directors) at theordinary general meeting of shareholders held on June 26, 2008. On January 30, 2009, our board of directors
resolved to issue stock acquisition rights to directors and executive officers and subsequently allotted anaggregate of 5,409 stock acquisition rights on February 16, 2009. As the directors of Mizuho Financial Group,
our directors received 435 stock acquisition rights. Each stock acquisition right represents a right to purchase1,000 shares of our common stock at ¥1 per share of common stock. The period during which the stockacquisition rights may be exercised shall be until February 16, 2029. Their exercise is conditioned on the holder
losing his or her status as director or executive officer. The book value of each stock acquisition right was¥190,910 as of March 31, 2010.
On September 3, 2009, our board of directors resolved to issue stock acquisition rights to directors andexecutive officers and subsequently allotted an aggregate of 5,835 stock acquisition rights on September 25,

6.C. Board Practices
Pursuant to our articles of incorporation, we maintain a corporate governance system consisting of general
meetings of shareholders, individual directors, board of directors, individual corporate auditors, board ofcorporate auditors and an accounting auditor as its primary components.
Our board of directors has the ultimate responsibility for the administration of our affairs. Our articles ofincorporation provide for a board of directors consisting of not more than 15 members, in order to facilitate
efficient and responsive decision making, and provide for not more than six corporate auditors. All directors andcorporate auditors are appointed by our shareholders at general meetings. The normal term of office is two years
for directors and four years for corporate auditors after their respective appointment, but directors and corporate
auditors may serve any number of consecutive terms. Our board of directors designates, from among its
members, representative directors and appoints a president. Our board of directors may also appoint a chairman,a deputy chairman, deputy presidents, senior managing directors and managing directors. Each representative
director has the authority to represent us in the conduct of our affairs.
While one of our corporate auditors is a certified public accountant, our corporate auditors are not required
to be certified public accountants. None of the corporate auditors may at the same time be directors, accounting
participants, executive officers, or managers or employees of the company or any of its subsidiaries and at least
one-half of them must be persons who have not been directors, accounting participants, executive officers or any
other employees of us or any of our subsidiaries at any time prior to their appointment as corporate auditors.
Each corporate auditor has a statutory duty to audit the directors’ performance of their duties and to audit theaccounting records and the business reports submitted by the directors to general meetings of shareholders.
Corporate auditors shall attend each meeting of the board of directors and, when necessary, state their opinion at
the meeting, but are not entitled to vote.
The board of corporate auditors is composed of all corporate auditors. The board of corporate auditors has astatutory duty to prepare and submit an audit report to the directors each year. If any corporate auditor has an
opinion that is different from the opinion of the board of corporate auditors, such opinion shall also be describedin the audit report. The board of corporate auditors shall determine policies regarding audits, the method ofinvestigation by the corporate auditors into the status of corporate affairs and financial position and other mattersrelating to the performance of the corporate auditors’ duties, provided, however, that a resolution of the board ofcorporate auditors may not prevent any corporate auditor from exercising his or her own power.
None of our directors or corporate auditors has service contracts with us providing for benefits upon
termination of service.
Our articles of incorporation, in accordance with the Company Law, allow us to enter into an agreementwith outside directors and outside corporate auditors that limits their liabilities incurred in connection with theirservice. The limitation of the liabilities under such agreement must be the higher of either (i) a pre-determinedamount not less than ¥20 million or (ii) the amount prescribed in laws and regulations, which is currently
equivalent to two times the annual compensation to such outside director or outside corporate auditor. Pursuant
to the provisions, we have entered into such agreements with all of our outside directors and outside corporate
auditors that were in office at any time after June 2006.
Based on an amendment to the rules of the Tokyo Stock Exchange and the Osaka Securities Exchange,
companies listed on those stock exchanges are required to have at least one member of the board of directors or131

the board of corporate auditors to be “independent” by the date of the general meeting of shareholders withrespect to the fiscal year ended on or after March 1, 2010. Currently, three of our directors and three of ourcorporate auditors meet such independence requirements.
To ensure transparency and objectivity in personnel matters relating to directors, we have established anominating committee and a compensation committee. Each committee is comprised of six members, of whomthree are outside directors.
For additional information on our directors and corporate auditors and our board practices, see“Item 6.A. Directors and Senior Management—Directors and Corporate Auditors” and “Item 10.B. Additional
Information—Memorandum and Articles of Association” in this annual report.
The rights of holders of American Depositary Receipts, or ADRs, which evidence ADSs, including such
ADR holders’ rights relating to corporate governance practices, are governed by the deposit agreement, which isincluded as Exhibit 2.3 to this annual report.
Corporate Governance Practices
Companies listed on the New York Stock Exchange, or NYSE, must comply with certain standards
regarding corporate governance under Section 303A of the NYSE Listed Company Manual. However,
NYSE-listed companies that are foreign private issuers meeting certain criteria, such as us, are permitted tofollow home country practices in lieu of certain provisions of Section 303A, and we are relying on thisexemption. See “Item 16.G. Corporate Governance” for a summary of significant ways in which our corporate
governance practices differ from those followed by NYSE-listed U.S. companies.
6.D. Employees
As of March 31, 2008, 2009 and 2010, we had 49,114, 50,191 and 57,014 employees, respectively, on aconsolidated basis, including overseas local staff but excluding advisers and temporary employees. We also had

FINANCIAL INFORMATION

8.A. Consolidated Statements and Other Financial Information
Financial Statements
Our consolidated financial statements are set forth in this annual report under “Item 18. Financial
Statements.”
Legal Proceedings
We are involved in normal collection proceedings initiated by us and other legal proceedings in the ordinary
course of our business.
An Indonesian subsidiary of ours acts as collateral agent for the trustee of bond issuances made bysubsidiaries of Asia Pulp & Paper Company Ltd. (“APP”). In that role, the subsidiary is involved in disputes
between the bondholders and such APP subsidiaries in their capacities as the issuers, guarantors and/or pledgorsof security for the bonds relating to foreclosure proceedings on the collateral and has been named as a defendantin lawsuits brought by the obligors under the bonds in Indonesia. Our consolidated financial statements do notinclude a reserve in relation to these disputes because we do not believe the resolution of this matter will have asignificant impact on our consolidated financial condition or results of operations, although there can be noassurance as to the foregoing.
Dividend Policy
We have pursued “strengthening of stable capital base” and “steady returns to shareholders” as our“disciplined capital management,” and have been putting more priority on “strengthening of stable capital base,”considering global discussions about capital adequacy and the uncertainty of economic and market trends.
Based on the above policy, we paid cash dividends for the fiscal year ended March 31, 2010 of ¥8 per shareof common stock, a decrease of ¥2 from the previous fiscal year. With respect to each class of preferred stock,
we made dividend payments for the fiscal year ended March 31, 2010 as prescribed.
Although our articles of incorporation provide for our ability to distribute an interim dividend toshareholders of record as of September 30 in each year pursuant to Article 454 Paragraph 5 of the Company Law,
we have been distributing dividends only once per year.
The distribution of surplus for the fiscal year end is subject to the authorization by a general meeting ofshareholders, while the distribution of surplus for the interim period is made by resolution of our board of
directors.
We will apply retained earnings to funds for strengthen our financial condition and to the development ofour business going forward.
8.B. Significant Changes
Except as disclosed in note 34 to our consolidated financial statements, no significant change in our
financial position has occurred since the date of the financial statements included in this annual report.

ADDITIONAL INFORMATION

10.B. Memorandum and Articles of Association
Objects and Purposes in our Articles of Incorporation
Our corporate purpose, as specified in article 2 of our articles of incorporation, which is included in thisannual report as Exhibit 1.1, is to engage in the following businesses as a bank holding company:•

operation and management of bank holding companies, banks, long-term credit banks, specialized
securities companies and other companies which we may own as our subsidiaries under the Banking
Law; and•any other business incidental to the foregoing.

Our Board of Directors
There is no provision in our articles of incorporation as to our directors’ power to vote on a proposal,
arrangement or contract in which a director is materially interested. The Company Law, however, requires suchdirector to refrain from voting on such matters at meetings of the board of directors.
The Company Law provides that compensation for directors be determined at a general meeting ofshareholders. Our board of directors will determine the compensation for each director without exceeding theupper limit on the aggregate amount of compensation for directors as a group approved by the general meeting ofshareholders. Our board of directors may, by its resolution, leave this decision to the discretion of our president.
The Company Law provides that the board of directors must approve significant loans from any third party
to the company.
Neither the Company Law nor our articles of incorporation set a mandatory retirement age for our directors.
There is no requirement concerning the number of shares an individual must hold to qualify as a director
under the Company Law or our articles of incorporation.
Common Stock
GeneralSet forth below is information concerning our shares of common stock, including brief summaries of certain
provisions of our articles of incorporation, our share handling regulations and the Company Law (Kaisha Hou)
(Law No. 86 of 2005, as amended) relating to joint stock corporations (kabushiki kaisha) and certain related
legislation, all as currently in effect.
Where relevant to the common stock, provisions of our preferred stock are also described below.
Distribution of Surplus
GeneralUnder the Company Law, distribution of cash or other assets by a joint stock corporation to its shareholders,
including dividends, takes the form of distribution of Surplus (as defined in “—Restriction on Distribution of
Surplus”). We are permitted to make distributions of Surplus to our shareholders any number of times per fiscal
year pursuant to resolutions of our general meeting of shareholders, subject to certain limitations described in141

“—Restriction on Distribution of Surplus.” Distributions of Surplus are required in principle to be authorized bya resolution of a general meeting of shareholders. Distributions of Surplus are, however, permitted pursuant to a
resolution of the board of directors if:(1) our articles of incorporation so provide (our current articles of incorporation do not have suchprovision);(2) the normal term of office of our directors is one year; and(3) our non-consolidated annual financial statements and certain documents for the latest fiscal year
fairly present our assets and profit and loss, as required by an ordinance of the Ministry of Justice.
In an exception to the above rule, even if the requirements described in (1) through (3) are not met, we are
permitted to make distributions of Surplus in cash to our shareholders by resolutions of the board of directors
once per fiscal year if our articles of incorporation so provide. Our current articles of incorporation provide such
distribution of Surplus as interim dividends, the record date for which is September 30 each year.
Distributions of Surplus may be made in cash or in kind in proportion to the number of shares of common
stock held by each shareholder. A resolution of a general meeting of shareholders or the board of directors
authorizing a distribution of Surplus must specify the kind and aggregate book value of the assets to be
distributed, the manner of allocation of such assets to shareholders, and the effective date of the distribution. If a
distribution of Surplus is to be made in kind, we may, pursuant to a resolution of a general meeting ofshareholders or (as the case may be) the board of directors, grant the right to our shareholders to require us tomake such distribution in cash instead of in kind. If no such right is granted to shareholders, the relevant
distribution of Surplus must be approved by a special resolution of a general meeting of shareholders (see“—Voting Rights” with respect to a “special resolution”).
Under our articles of incorporation, the record date for annual dividends and interim dividends is March 31 and
September 30, respectively, in each year. In Japan, the “ex-dividend date” (the date from which purchasers of sharesthrough Japanese stock exchanges will not be entitled to the dividends to be paid to registered shareholders as of any
record date) and the record date for dividends precede the date of determination of the amount of the dividend to be
paid. The ex-dividend date of the shares of common stock is generally the second business day prior to the record
date. Under our articles of incorporation, we are not obligated to pay any distribution of Surplus to be made in cash
which has not been received after the lapse of five years from the commencement date of such distribution.
Restriction on Distribution of Surplus
Payment of annual dividends on shares of common stock is subject to the prior payment of dividends onshares of preferred stock of ¥20 per share of eleventh series class XI preferred stock and ¥30 per share ofthirteenth series class XIII preferred stock. Payment of an interim dividend on shares of our common stock isalso subject to the prior payment of an interim preferred dividend of one-half the annual preferred dividend
amount on the shares of the two series of preferred stock.
In making a distribution of Surplus, we must set aside in our additional paid-in capital and/or legal reserve
an amount equal to one-tenth of the amount of Surplus so distributed, until the sum of its additional paid-in
capital and legal reserve reaches one-quarter of its stated capital.
The amount of Surplus at any given time must be calculated in accordance with the following formula:
A + B + C + D - (E + F + G)
In the above formula:“A” = the total amount of other capital surplus and other retained earnings, each such amount being thatappearing on our non-consolidated balance sheet as of the end of the last fiscal year
“B” = (if we have disposed of our treasury stock after the end of the last fiscal year) the amount of theconsideration for such treasury stock received by us less the book value thereof142

“C” = (if we have reduced our stated capital after the end of the last fiscal year) the amount of such
reduction less the portion thereof that has been transferred to additional paid-in capital or legal reserve (ifany)“D” = (if we have reduced our additional paid-in capital or legal reserve after the end of the last fiscal year)
the amount of such reduction less the portion thereof that has been transferred to stated capital (if any)“E” = (if we have cancelled our treasury stock after the end of the last fiscal year) the book value of suchtreasury stock“F” = (if we have distributed Surplus to our shareholders after the end of the last fiscal year) the total bookvalue of the Surplus so distributed“G” = certain other amounts set forth in an ordinance of the Ministry of Justice, including:•

if we have reduced Surplus and increased our stated capital, additional paid-in capital or legal reserve
after the end of the last fiscal year, the amount of such reduction; and•if we have distributed Surplus to shareholders after the end of the last fiscal year, the amount set aside in
our additional paid-in capital or legal reserve, if any, as required by ordinances of the Ministry ofJustice.

The aggregate book value of Surplus distributed by us may not exceed a prescribed distributable amount(the “Distributable Amount”), as calculated on the effective date of such distribution. The Distributable Amountat any given time shall be the amount of Surplus less the aggregate of (a) the book value of our treasury stock,(b) the amount of consideration for any of our treasury stock disposed of by us after the end of the last fiscal year
and (c) certain other amounts set forth in an ordinance of the Ministry of Justice, including (if the sum of
one-half of our goodwill and deferred assets exceeds the total of the stated capital, additional paid-in capital andlegal reserve, each such amount being the amount in our non-consolidated balance sheet as of the end of the last
fiscal year) all or certain part of such exceeding amount as calculated in accordance with the ordinances of the
Ministry of Justice.
If we have become at our option a company with respect to which its consolidated balance sheet should also
be considered in the calculation of the Distributable Amount (renketsu haito kisei tekiyo kaisha), we shall further
deduct from the amount of Surplus the excess amount, if any, of (x) the total amount of the shareholders’ equity
appearing on our non-consolidated balance sheet as of the end of the last fiscal year and certain other amounts set
forth by an ordinance of the Ministry of Justice over (y) the total amount of the shareholders’ equity and certain
other amounts set forth by an ordinance of the Ministry of Justice appearing on our consolidated balance sheet asof the end of the last fiscal year. We did not opt for becoming such a company with respect to the fiscal year
ended March 31, 2010.
If we have prepared interim financial statements as described below, and if such interim financial statements
have been approved by the board of directors or (if so required by the Company Law) by a general meeting ofshareholders, then the Distributable Amount must be adjusted to take into account the amount of profit or loss,
and the amount of consideration for any of our treasury stock disposed of by us, during the period in respect ofwhich such interim financial statements have been prepared. We may prepare non-consolidated interim financial
statements consisting of a balance sheet as of any date subsequent to the end of the last fiscal year and an income
statement for the period from the first day of the current fiscal year to the date of such balance sheet. Interim
financial statements so prepared by us must be audited by our corporate auditors and/or outside accounting
auditor, as required by an ordinance of the Ministry of Justice.
Capital and Reserves
We may reduce our additional paid-in capital or legal reserve generally by resolution of a general meetingof shareholders and, if so decided by the same resolution, may account for the whole or any part of the amount ofsuch reduction as stated capital. On the other hand, we may reduce our stated capital generally by special
resolution of a general meeting of shareholders and, if so decided by the same resolution, may account for the143whole or any part of the amount of such reduction as additional paid-in capital or legal reserve. In addition, we
may reduce our Surplus and increase either (i) stated capital or (ii) additional paid-in capital and/or legal reserveby the same amount, in either case by resolution of a general meeting of shareholders.
Stock Splits
We may at any time split shares of common stock into a greater number of shares of common stock byresolution of the board of directors. When a stock split is to be made, so long as our only class of outstanding
stock is the common stock, we may increase the number of authorized shares in the same ratio as that of suchstock split by amending our articles of incorporation, of which amendment may be effected by resolution of theboard of directors without approval by shareholders.
Abolishment of Fractional Share System
With the implementation of the electronic share certificate system for listed shares under the Law for Partial
Amendments to the Law Concerning Book-entry Transfer of Corporate Bonds and Other Securities for the
Purpose of Streamlining the Settlements of Trades of Stocks and Other Securities (Law No. 88 of 2004) whichbecame effective on January 5, 2009, all listed shares became eligible for book-entry transfer. However, because
fractional shares are not eligible for book-entry transfer and are not handled under the new “book-entry transfer
system”, we implemented the allotment of shares or fractions of a share without consideration to the shareholders
or the holders of fractional shares in order to abolish all the fractional shares. The shares and fractions of a share
were allotted on January 4, 2009 in proportion to the number of shares of common stock, shares of each class ofpreferred stock and fractional shares held by the holders thereof, in each case without any additional
consideration, at the rate of 999 shares per 1 share and 9.99 shares per every 0.01 of a share. As a result, currently
there are no outstanding fractional shares.
Unit Share System
We have adopted the unit share system under which shareholders will have one voting right for each unit ofshares consisting of 100 shares held by them at general meetings of shareholders or at meetings of holders of aparticular class of shares, and shares constituting less than a full unit will carry no voting rights. See “—Preferred
Stock—Voting Rights” for information on the voting rights that holders of preferred stock may have at general
meetings of shareholders. Our articles of incorporation provide that the holders of shares constituting less than afull unit will not have shareholder rights, except for those specified in an ordinance of the Ministry of Justicewhich include rights (i) to receive dividends, (ii) to receive cash or other assets in case of a consolidation or splitof shares, share exchange or share transfer, or merger or (iii) to be allotted rights to subscribe for free for new
shares and stock acquisition rights when such rights are granted to shareholders. Holders of shares constituting
less than a full unit may at any time request us to purchase such shares constituting less than a full unit (a) at thecurrent market price as determined pursuant to the Company Law in cases of such shares having a market price(such as our common stock) or (b) at the price as determined through negotiations between the holders of sharesconstituting less than a full unit and us in cases where such shares have no market price (such as our preferredstock), which request may not be withdrawn without our consent. In addition, holders of shares constituting lessthan a full unit may require us to sell them such number of shares, which, when combined with the number ofshares already held by such holder, shall constitute a whole unit of shares; provided that we will be obliged tocomply with such request only when we own a sufficient number of shares to accommodate such request. As
prescribed in our share handling regulations, such requests shall be made through an account managing
institution at which such shareholder has its account and Japan Securities Depository Center, Inc. (“JASDEC”)
pursuant to the rules of JASDEC, without going through the notification procedure required for the exercise ofshareholders’ rights entitled regardless of record dates as described in “—Transfer of Shares. ” The board of
directors may reduce the number of shares constituting one unit of shares or cease to use the unit share system byamendments to the articles of incorporation without a special resolution of the general meeting of shareholders
which would otherwise be required.
144

General Meetings of Shareholders
The ordinary general meeting of shareholders shall be held no later than three months from the last day ofeach business year and is normally held in June of each year. In addition, we may hold an extraordinary general
meeting of shareholders whenever necessary. Notice of a general meeting of shareholders stating the place, thetime and the purpose thereof must be given to each shareholder having voting rights (or, in the case of a
non-resident shareholder, to its standing proxy or mailing address in Japan) at least two weeks prior to the dateset for the meeting. The record date for an ordinary general meeting of shareholders is March 31 of each year.
Any shareholder holding at least 300 voting rights or 1% of the total number of voting rights for six months
or longer may propose a matter to be considered at a general meeting of shareholders by submitting a request to arepresentative director at least eight weeks prior to the date of such meeting. Any of the minimum percentages,
time periods and number of voting rights necessary for exercising the minority shareholder rights describedabove may be decreased or shortened if our articles of incorporation so provide.
Voting Rights
Our shareholders have one voting right for each unit of shares held by them (regarding the voting rights heldby holders of preferred stock, see “—Preferred Stock—Voting Rights”).
Except as otherwise provided by law or in our articles of incorporation, a resolution shall be adopted at a
general meeting of shareholders by a majority of the voting rights held by the shareholders present at themeeting. Our articles of incorporation provide that the quorum for election of directors and corporate auditors is
one-third of the total number of voting rights. Our shareholders are not entitled to cumulative voting in theelection of directors. A shareholder may exercise its voting rights in writing or through a proxy, provided that theproxy shall also be a holder of our shares having voting rights at such meeting.
The Company Law provides that certain important matters shall be approved by a “special resolution” of ageneral meeting of shareholders. Under our articles of incorporation, the quorum for a special resolution is
one-third of the total number of voting rights, and the approval of not less than two-thirds of the voting rights
held by the shareholders present at the meeting is required for adopting a special resolution. Such importantmatters include:
1.

any amendment to our articles of incorporation (except for such amendments that may be authorized by
the board of directors under the Company Law such as (i) an increase of the number of authorizedshares in the same ratio as that of a stock split, (ii) a reduction of the number of shares per unit ofshares and (iii) abolishing the unit share system);2.

dismissal of a corporate auditor;

3.

our dissolution, merger or consolidation requiring shareholders’ approval;

4.

establishment of a parent and wholly-owned subsidiary relationship by way of a share transfer(kabushiki-iten) or share exchange (kabushiki-kokan) requiring shareholders’ approval;

5.

transfer of the whole or a substantial part of our business;

6.

taking over of the whole of the business of another company requiring shareholders’ approval;

7.

our corporate split requiring shareholders’ approval;

8.

consolidation of shares of common stock;9.

acquisition of shares of common stock by us from a specific shareholder other than our subsidiary;

10. distribution of Surplus in kind (except when shareholders are granted the right to require to make such
distribution in cash instead of in kind);145

11. issuance or transfer of new shares or existing shares held by us as treasury stock to persons other than
the shareholders at a “specially favorable” price; and12. issuance of stock acquisition rights (including those incorporated in bonds with stock acquisitionrights) to persons other than the shareholders at a “specially favorable” price or under “speciallyfavorable” conditions.
Liquidation Rights
In the event of our liquidation, the assets remaining after payment of all debts, liquidation expenses, taxes
and distributions of residual assets relating to the then outstanding preferred stock will be distributed among
holders of common stock in proportion to the respective numbers of shares held by them. See “—Preferred
Stock—Liquidation Rights.”
Issue of Additional Shares and Pre-emptive Rights
Holders of the common stock have no pre-emptive rights. Authorized but unissued shares of common stock
may be issued at such times and upon such terms as the board of directors determines, subject to the limitations
as to the issuance of new shares of common stock at a “specially favorable” price mentioned in “—Voting
Rights.” In the case of an issuance or transfer of shares or stock acquisition rights by way of an allotment to athird party which would dilute the outstanding voting shares by 25% or more or change the controllingshareholder, in addition to a board resolution, the approval of the shareholders or an affirmative opinion from aperson independent of our management is generally required pursuant to the regulations of the stock exchanges
in Japan. The board of directors may, however, determine that shareholders of a particular class of stock shall begiven subscription rights to new shares of the same class, in which case they must be given on uniform terms toall shareholders of that class as of a record date of which not less than two weeks’ prior public notice must be
given. Each of the shareholders to whom such rights are given must also be given at least two weeks’ prior noticeof the date on which such rights expire (but see “—Preferred Stock—Issue of Additional Shares and Pre-emptive
Rights” regarding our preferred stock).
Stock Acquisition Rights
We may issue stock acquisition rights (shinkabu yoyakuken). Holders of stock acquisition rights are entitledto acquire shares from us, upon payment of the applicable exercise price, and subject to other terms andconditions thereof. We may also issue bonds with stock acquisition rights (shinkabu yoyakuken-tsuki shasai). The
issuance of stock acquisition rights and bonds with stock acquisition rights may be authorized by the board of
directors unless it is made at a “specially favorable” price or under “specially favorable” conditions, as describedin “—Voting Rights.”
Record Date
As mentioned above, March 31 is the record date for the payment of annual dividends and the determinationof shareholders entitled to vote at the ordinary general meeting of shareholders. September 30 is the record date
for the payment of interim dividends. In addition, by a resolution of the board of directors and after giving atleast two week’s prior public notice, we may at any time set a record date in order to determine the shareholders
who are entitled to certain rights pertaining to our stock.
JASDEC is required to give us notice of the names and addresses of our shareholders, the numbers of shares
held by them and other relevant information as of such record date promptly after we set each record date.

146

Acquisition by Us of Common Stock
We may acquire shares of common stock:1.

by way of purchase on any Japanese stock exchange on which the shares of our common stock arelisted or by way of tender offer (in either case pursuant to a resolution of the board of directors as
currently authorized by our articles of incorporation);2.

from a specific shareholder other than any of our subsidiaries (pursuant to a special resolution of ageneral meeting of shareholders); or

3.

from any of our subsidiaries (pursuant to a resolution of the board of directors).

In the case of 2. above, any other shareholder may make a request to a representative director to be included as aseller in the proposed purchase, unless the purchase price or any other consideration to be received by therelevant specific shareholder will not exceed the last trading price of the shares on the relevant stock exchange on
the day immediately preceding the date on which the resolution mentioned in 2. above was adopted (or, if there isno trading in the shares on the stock exchange or if the stock exchange is not open on such day, the price atwhich the shares are first traded on such stock exchange thereafter).
The total amount of the purchase price of shares of common stock may not exceed the Distributable
Amount, as described in “—Distribution of Surplus—Restriction on Distribution of Surplus.”
We may hold the shares of common stock acquired, and may generally transfer or cancel such shares byresolution of the board of directors.
Disposal of Shares of Common Stock Held by Shareholders whose Location is Unknown
We are not required to send notices to a shareholder if notices given by us to such shareholder fail to arrive forfive consecutive years or more at its address registered in our register of shareholders or otherwise notified to us.
In the above case, if the relevant shareholder also fails to receive dividends on the shares continuously forfive years or more at its address registered in our register of shareholders or otherwise notified to us, then we
may in general dispose of such shares at their then market price and hold or deposit the proceeds of suchdisposition on behalf of the relevant shareholder.
Reporting of Substantial Shareholders
The Financial Instruments and Exchange Law and its related regulations require any person who has
become, beneficially and solely or jointly, a holder of more than 5% of the total issued shares of capital stock of
a company that is listed on any Japanese stock exchange to file a report with the Director of the relevant Local
Finance Bureau of the Ministry of Finance within five business days. With certain exceptions, a similar reportmust also be filed in respect of any subsequent change of 1% or more in the holding or of any change in material
matters set forth in any previously filed reports. For this purpose, shares issuable to such person upon conversionof convertible securities or exercise of share subscription warrants or stock acquisition rights are taken into
account in determining both the number of shares held by the holder and the company’s total issued share capital.
Copies of each report must also be furnished to the company issuing the shares and to all the Japanese stock
exchanges on which the shares are listed.
There are other reporting requirements under the Banking Law. See “Item 4.B. Information on the
Company—Business Overview—Supervision and Regulation—Japan—Examination and Reporting Applicableto Shareholders.”

147

Holding of Shares of Our Common Stock by Foreign Investors
There are no limitations imposed by the laws of Japan, our articles of incorporation or our other constituent
documents on the rights of non-residents or foreign shareholders to hold or exercise voting rights on our shares ofcommon stock or preferred stock.
Transfer of Shares
At present, JASDEC is the only institution that is designated by the relevant authorities as a clearing house
which is permitted to engage in the clearing operations of listed shares under the Law Concerning Book-Entry
Transfer of Corporate Bonds, Stocks, etc. (Law No. 75 of 2001, including regulations promulgated thereunder;
the “Book-entry Law”). Under the clearing system above, in order for any person to hold, sell or otherwise
dispose of listed shares, such person must have an account at an account managing institution unless such person
has an account at JASDEC. “Account managing institutions” are financial instruments business operators (i.e.,
securities companies), banks, trust companies and certain other financial institutions which meet therequirements prescribed by the Book-entry Law, and only those financial institutions that meet further stringent
requirements of the Book-entry Law can open accounts directly at JASDEC. Under the Book-entry Law, anytransfer of shares is effected through book entry, and title to the shares passes to the transferee at the time when
the transferred number of the shares is recorded at the transferee’s account at an account managing institution.
The holder of an account at an account managing institution is presumed to be the legal owner of the shares heldin such account. Under the Company Law and the Book-entry Law, in order to assert shareholders’ rights towhich shareholders as of record dates are entitled (such as the rights to vote at a general meeting of shareholders
or receive dividends) against us, a shareholder must have its name and address registered in our register ofshareholders. Under the clearing system, such registration is made upon our receipt of necessary informationfrom JASDEC. On the other hand, in order to assert shareholders’ rights to which shareholders are entitledregardless of record dates such as minority shareholders’ rights including the right to propose a matter to beconsidered at a general meeting of shareholders, except for shareholders’ rights to request us to purchase or sellshares constituting less than a full unit (as described in “—Unit Share System”), upon the shareholder’s request,
JASDEC shall issue a notice of certain information, including the name and address of such shareholder, to us.
Thereafter, such shareholder is required to present us a receipt of the request of the notice in accordance with ourshare handling regulations. Under the Book-entry Law, the shareholder shall exercise such shareholders’ rightwithin four weeks after the notice above. Non-resident shareholders are required to appoint a standing proxy inJapan or provide a mailing address in Japan. Each such shareholder must give notice of such standing proxy or
mailing address to the relevant account managing institution. Such notice will be forwarded to us through
JASDEC. Japanese securities companies and commercial banks customarily act as standing proxies and provide
related services for standard fees. Notices from us to non-resident shareholders are delivered to such standing
proxies or mailing addresses.
Under the clearing system, shares constituting less than one unit are transferable. Under the rules of theJapanese stock exchanges, however, shares constituting less than one unit do not comprise a trading unit, except
in limited circumstances, and accordingly may not be sold on Japanese stock exchanges.
Our transfer agent is Mizuho Trust & Banking, located at 2-1, Yaesu 1-chome, Chuo-ku, Tokyo 103-8670,
Japan.

As of March 31, 2010, 914,752,000 shares of eleventh series class XI preferred stock and 36,690,000 sharesof thirteenth series class XIII preferred stock were issued and there were no fractional shares of each series ofpreferred stock.
Preferred Dividends
Payment of annual dividends on shares of common stock is subject to the prior payment on shares ofpreferred stock. The amount of preferred dividends for each type of outstanding preferred stock is as follows:•

Eleventh series class XI preferred stock bears an annual non-cumulative dividend of ¥20 per share, andin the event we pay an interim dividend, holders are entitled to receive ¥10 per share in preference tocommon stock.

•Thirteenth series class XIII preferred stock bears an annual non-cumulative dividend of ¥30 per share,and in the event we pay an interim dividend, holders are entitled to receive ¥15 per share in preference
to common stock.

The amount of any preferred interim dividend will be deducted from the preferred dividend payable onpreferred stock in respect of the same fiscal year.
No payment of dividends on our preferred stock or any other stock may be made unless we have sufficient
Distributable Amount and a resolution to pay such dividend is obtained at the relevant ordinary general meetingof shareholders, in the case of annual dividends or at the board of directors, in the case of preferred interim
dividends.
Dividends on our preferred stock are non-cumulative. If the full amount of any dividend is not declared on
our preferred stock in respect of any fiscal year, holders of our preferred stock do not have any right to receive
dividends in respect of the deficiency in any subsequent fiscal year, and we will have no obligation to pay the
deficiency or to pay any interest regardless of whether or not dividends are paid in respect of any subsequentfiscal year. The holders of our preferred stock are not entitled to any further dividends or other participation in or
distribution of surplus.
Liquidation Rights
In the event of our voluntary or involuntary liquidation, holders of our preferred stock will be entitled,equally in rank as among themselves and in preference over shares of common stock, to receive a distribution of¥1,000 per share out of our residual assets upon our liquidation in the case of eleventh series class XI and

•from the close of any ordinary general meeting of shareholders if a proposed resolution to declare apreferred dividend is not approved at such meeting,until in each case such time as a resolution of an ordinary general meeting of shareholders declaring a preferred
dividend is approved.
A separate resolution of a meeting of the holders of the preferred stock is required in order to approve thefollowing matters which would prejudice the interests of the holders of the relevant preferred stock:(i)an amendment to the articles of incorporation to add new classes of shares to be issued, alter theterms of the shares or increase the number of authorized number of shares or authorized number ofany class of shares, with certain exceptions;(ii)

Such separate resolution is not required when the articles of incorporation so provide, except in the case of(i) above.
Ranking
We will not (unless the requisite sanction has been given by holders of preferred stock) create or issue anyother shares ranking, as regards order of participation in the profits or assets of us on a liquidation or otherwise,in priority to the preferred stock in issue, but we may issue, without obtaining the consent of holders of thepreferred stock in issue, other preferred stock ranking pari passu with the preferred stock in issue as regards theorder of such participation in profits or assets of us and carrying such rights as to rates of preferred dividends orterms of conversion as the board of directors may determine, subject to the limitations set forth in our articles ofincorporation and the Company Law.
Acquisition of Preferred Stock
We may, if required, subject to regulatory approval, acquire any shares of the preferred stock thenoutstanding at any time out of the Distributable Amount (as defined in “—Common Stock—Restriction on
Distribution of Surplus”). We may also, acquire all or a portion of the thirteenth series class XIII preferred stockon or after April 1, 2013 at a price of ¥1,000 per share, with the equivalent amount of preferred dividends
accrued to such acquisition, without consent of the holders of such preferred stock. When a portion of a certainclass of preferred stock is acquired, such acquisition shall be made from each holder thereof in number of shares
determined by way of a lot or pro rata allocation.
Stock Splits
Our articles of incorporation provide that no stock split, stock consolidation or free distribution of stock
shall be made in respect of the preferred stock unless otherwise provided for in any law or regulation.
150

Issue of Additional Shares and Pre-emptive Rights
Our articles of incorporation provide that no holder of our preferred stock has any pre-emptive right tosubscribe for or purchase shares, stock acquisition rights or bonds with stock acquisition rights in the event of anissuance of additional shares or bonds and that no free distribution of stock acquisition rights may be made to theholders of our preferred stock.
Conversion
Our articles of incorporation provide that holders of class XI or XII (currently not in issue) preferred stock
may, at their option, convert their shares to common stock by requesting us to acquire such shares and issue ortransfer common stock to them. Other classes of our preferred stock outstanding are non-convertible.
Our articles of incorporation also provide that class XI or XII (currently not in issue) preferred stock
outstanding on the last day of the acquisition period will be mandatorily acquired by us on the immediately
following day (the “mandatory conversion date”) in consideration of shares of common stock of which number
shall be calculated at the then-current market price per share of our common stock (the “mandatory conversion
price”).
Eleventh series class XI preferred stock may, at the option of the holder thereof, be acquired at any timefrom July 1, 2008 to June 30, 2016 in consideration of shares of common stock of which number shall becalculated at ¥286.20 per share, subject to anti-dilution adjustments due to, among other things, issuance of newshares of our common stock at issue price below the market price. For the purpose of determining the mandatory
conversion price and the conversion price adjusted pursuant to the anti-dilution clause, the market price shallmean the average price of daily closing prices of our common stock on the Tokyo Stock Exchange for the 30
consecutive trading days commencing on the 45th trading day prior to the mandatory conversion date or the dateon which the conversion price after the adjustment becomes effective, respectively. Anti-dilution adjustments are
triggered upon an issuance of common stock at prices that are lower than the then current market price, stock
splits and free allotments of common stock, and other similar events, so that the impact of these events areproperly reflected in the conversion price.
The anti-dilution adjustments will generally be made in accordance with the following formula.

“acquisition” is used in lieu of “conversion” in our articles of incorporation.
10.C. Material Contracts
There were no material contracts entered into by us for the two years preceding the filing of this annual
report that were not entered into in the ordinary course of business.

151

10.D. Exchange Controls
Foreign Exchange and Foreign Trade Law
The Foreign Exchange and Foreign Trade Law of Japan and the cabinet orders and ministerial ordinances
incidental thereto, collectively the Foreign Exchange Law, set forth, among other matters, the regulations relating
to the receipt by non-residents of Japan of payment with respect to shares to be issued by us and the acquisitionand holding of shares by non-residents of Japan and foreign investors, both as defined below. It also applies insome cases to the acquisition and holding of ADSs representing such shares acquired and held by non-residents
of Japan and by foreign investors. Generally, the Foreign Exchange Law currently in effect does not affect theright of a non-resident of Japan to purchase or sell ADSs outside Japan for non-Japanese currency.
“Non-residents of Japan” are defined as individuals who are not resident in Japan and corporations whose
principal offices are located outside Japan. Generally, the branches and offices of non-resident corporations thatare located in Japan are regarded as residents of Japan while the branches and offices of Japanese corporations
located outside Japan are regarded as non-residents of Japan.
“Foreign investors” are defined as:•

individuals not resident in Japan;•

judicial persons or other organizations that are organized under the laws of foreign countries or whose
principal offices are located outside Japan;•

corporations of which 50% or more of the shares are held by individuals not resident of Japan and/or
judicial persons or other organizations that are organized under the laws of foreign countries or whose
principal offices are located outside Japan; and•judicial persons or other organizations, a majority of officers (or a majority of officers having the powerof representation) of which are non-resident individuals.

Dividends and Proceeds of Sales
Under the Foreign Exchange Law, dividends paid on, and the proceeds of sales in Japan of, shares held by
non-residents of Japan may in general be converted into any foreign currency and repatriated abroad. The
acquisition of our shares by non-residents of Japan by way of a stock split is not subject to any notification orreporting requirements.
Acquisition of Shares
In general, a non-resident of Japan who acquires shares from a resident of Japan is not subject to any priorfiling requirement, although the Foreign Exchange Law empowers the Minister of Finance of Japan to requireprior approval for any such acquisition in certain limited circumstances. While such prior approval is not
required in general, in the case where a resident of Japan transfers shares of a Japanese company forconsideration exceeding ¥100 million to a non-resident of Japan, the resident of Japan that transfers the shares isrequired to report the transfer to the Minister of Finance of Japan within 20 days from the date of the transfer,
unless the transfer is made through a bank or financial instruments business operator licensed or registered underJapanese law.
If a foreign investor acquires our shares and, together with parties who have a special relationship with that
foreign investor, holds 10% or more of our issued shares as a result of such acquisition, the foreign investor mustfile a report of such acquisition with the Minister of Finance and any other competent Minister on or before the15th day of the month following the month in which the acquisition was made, in principle. In certain limited
circumstances, however, a prior notification of such acquisition must be filed with the Minister of Finance andany other competent Minister, who may modify or prohibit the proposed acquisition.
152

Deposit and Withdrawal under American Depositary Facility
The deposit of shares with Mizuho Corporate Bank, in its capacity as custodian and agent for the depositary,in Tokyo, the issuance of ADSs by the depositary to a non-resident of Japan in respect of the deposit and thewithdrawal of the underlying shares upon the surrender of the ADR are not subject to any of the formalities or
restrictions referred to above. However, where as a result of a deposit or withdrawal the aggregate number ofshares held by the depositary, including shares deposited with Mizuho Corporate Bank as custodian for thedepositary, or the holder surrendering the ADR, as the case may be, would be 10% or more of the total
outstanding shares, a report will be required, and in specified circumstances, a prior notification may be required,
as noted above.
10.E. Taxation
Japanese Taxation
The following is a general summary of major Japanese tax consequences (limited to national tax) to holdersof shares of our common stock or ADSs representing shares of our common stock who are non-residents of Japanor non-Japanese corporations without a permanent establishment in Japan, which we refer to as “non-resident
holders” in this section. The statements regarding Japanese tax laws set forth below are based on the laws inforce and as interpreted by the Japanese tax authorities as at the date of this Annual Report and are subject tochanges in the applicable Japanese laws or tax treaties, conventions or agreements, or interpretations thereof,
occurring after that date. This summary is not exhaustive of all possible tax considerations that may apply to aparticular investor, and potential investors are advised to satisfy themselves as to the overall tax consequences of
the acquisition, ownership and disposition of shares of our common stock or ADSs, including specifically the tax
consequences under Japanese law, the laws of the jurisdiction of which they are resident, and any tax treaty,
convention or agreement between Japan and their country of residence, by consulting their own tax advisers.
For the purpose of Japanese tax law and the tax treaty between the United States and Japan, a U.S. holder of
ADSs will generally be treated as the owner of the shares underlying the ADSs evidenced by the ADRs.
Generally, a non-resident holder of shares of our common stock or ADSs is subject to Japanese income tax
collected by way of withholding on dividends paid by us, and such tax will be withheld prior to payment ofdividends. Stock splits are, in general, not a taxable event.
In the absence of any applicable tax treaty, convention or agreement reducing the maximum rate of Japanese
withholding tax or allowing exemption from Japanese withholding tax, the rate of Japanese withholding tax
applicable to dividends paid by Japanese corporations on their shares of stock to non-resident holders is generally
20% under Japanese tax law. However, with respect to dividends paid on listed shares issued by a Japanese
corporation (such as shares of our common stock or ADSs) to non-resident holders, other than any individual
shareholder who holds 5% or more of the total number of shares issued by the relevant Japanese corporation, theaforementioned 20% withholding tax rate is reduced to (i) 7% for dividends due and payable on or before
December 31, 2011 and (ii) 15% for dividends due and payable on or after January 1,2012.
Under the income tax treaty between the United States and Japan, the maximum rate of Japanese
withholding tax which may be imposed on dividends paid to a qualified United States resident eligible to enjoy
treaty benefits that is either a corporation owning, directly or indirectly, less than 10% of the voting stock of aJapanese corporation or an individual is generally reduced to 10% of the gross amount actually distributed,
except where such United States resident conducts business in Japan through a permanent establishment situatedtherein and the holding in respect of which the dividends are paid is effectively connected with such permanentestablishment. Dividends paid to pension funds which are qualified United States residents eligible to enjoy
treaty benefits are exempt from Japanese income taxation by way of withholding or otherwise unless such
dividends are derived from the carrying on of a business, directly or indirectly, by such pension funds. Under
Japanese tax law, any reduced maximum rate applicable under a tax treaty shall be available when such153

maximum rate is below the rate otherwise applicable under the Japanese tax law referred to in the preceding
paragraph with respect to the dividends to be paid by us on shares of our common stock or ADSs. A non-resident
holder of shares of our common stock who is entitled, under any applicable tax treaty, to a reduced rate ofJapanese withholding tax, or exemption therefrom, as the case may be, is required to submit an Application Formfor Income Tax Convention Regarding Relief from Japanese Income Tax on Dividends (together with any otherrequired forms and documents) in advance, through the withholding agent, to the relevant tax authority before
payment of dividends. A standing proxy for a non-resident holder may provide such application service. With
respect to ADSs, this reduced rate or exemption will be applicable to non-resident holders of ADSs if the
Depositary or its Agent submits two Application Forms (one before payment of dividends and the other withineight months after the record date concerning such payment of dividends ), together with certain otherdocuments. To claim this reduced rate or exemption, non-resident holders of ADSs will be required to file a
proof of taxpayer status, residence and beneficial ownership, as applicable, and to provide other information or
documents as may be required by the Depositary. Non-resident holders who are entitled, under any applicable tax
treaty, to a reduced rate of Japanese withholding tax below the rate otherwise applicable under Japanese tax law,or exemption therefrom, as the case may be, but fail to submit the required application in advance may
nevertheless be entitled to claim a refund from the relevant Japanese tax authority of withholding taxes withheld
in excess of the rate under an applicable tax treaty (if such non-resident holders are entitled to a reduced treaty
rate under the applicable tax treaty) or the full amount of tax withheld (if such non-resident holders are entitled toan exemption under the applicable tax treaty), as the case may be, by complying with a certain subsequent filingprocedure.
We do not assume any responsibility to ensure withholding at the reduced rate, or exemption therefrom, for
non-resident holders who would be so eligible under an applicable tax treaty but where the required proceduresas stated above are not followed.
Gains derived from the sale or other disposition of shares of our common stock or ADSs outside Japan by anon-resident holder, who is a portfolio investor, are not, in general, subject to Japanese income tax or corporation tax.
Any deposits or withdrawals of shares of our common stock by a non-resident holder in exchange for ADSs
are, in general, not subject to Japanese income or corporation tax.
Japanese inheritance and gift taxes, at progressive rates, may be payable by an individual who has acquired
our shares of our common stock or ADSs from an individual, as a legatee, heir or donee, even if none of theacquiring individual, the decedent or the donor is a Japanese resident.
U.S. Taxation
The following sets forth the material United States federal income tax consequences of the ownership ofshares and ADSs as of the date hereof. The discussion set forth below is applicable to U.S. holders (as defined
below) (i) who are residents of the United States for purposes of the current income tax treaty between Japan andthe United States (the “Treaty”), (ii) whose shares or ADSs are, for purposes of the Treaty, neither effectively
connected with nor attributable to a permanent establishment in Japan and (iii) who otherwise qualify for the full
benefits of the Treaty.
The following summary is not a complete analysis or description of all potential U.S. federal income tax
consequences to a particular U.S. holder. It does not address all U.S. federal income tax considerations that may be
relevant to all categories of potential purchasers, certain of which (such as banks or other financial institutions,insurance companies, dealers in securities or currencies, tax-exempt entities, non-U.S. persons, persons holding ashare or an ADS as part of a “straddle,” “hedge,” conversion or integrated transaction, partnerships or other passthrough entities for U.S. federal income tax purposes, traders in securities who have elected the mark-to-market
method of accounting for their securities, regulated investment companies, real estate investment trusts, holders
whose “functional currency” is not the U.S. dollar, holders liable for alternative minimum tax and holders of 10% or154more of our voting shares) are subject to special tax treatment. This summary does not address any foreign, state,
local or other tax consequences of investments in our shares or ADSs.
This summary addresses only shares or ADSs held as capital assets.
As used herein, a “U.S. holder” is a beneficial owner of shares or ADSs, as the case may be, that is, for U.S.
federal income tax purposes:•

an individual citizen or resident of the United States;•

a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created ororganized in or under the laws of the United States or any political subdivision thereof;•an estate, the income of which is subject to U.S. federal income tax regardless of its source; or•a trust if it (1) is subject to the primary supervision of a court within the United States and the control of
one or more U.S. persons as described in Section 7701(a)(30) of the Code or (2) has a valid election in
effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

If a partnership holds shares or ADSs, the tax treatment of a partner will generally depend on the status of
the partner and the activities of the partnership. If you are a partner of a partnership holding shares or ADSs, you
should consult your tax advisor.
The discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended (the“Code”), and regulations, rulings and judicial decisions thereunder as of the date hereof, and such authorities
may be replaced, revoked or modified so as to result in U.S. federal income tax consequences different fromthose discussed below. In addition, this summary is based, in part, upon representations made by the depositary
to us and assumes that the deposit agreement, and all other related agreements, will be performed in accordancewith their terms.
We urge U.S. holders to consult their own tax advisors concerning the U.S. federal, state and local and othertax consequences to them of the purchase, ownership and disposition of shares or ADSs.
The U.S. Treasury has expressed concerns that parties through whom ADSs are pre-released may be taking
actions that are inconsistent with the claiming of foreign tax credits by U.S. holders of ADSs. Such actions would
also be inconsistent with the claiming of the reduced rate of tax, described in “—U.S. Taxation—Taxation of
Dividends” below, applicable to dividends received by certain non-corporate holders. Accordingly, the analysisof the creditability of Japanese taxes and the availability of the reduced tax rate for dividends received by certain
non-corporate holders, each described in “—U.S. Taxation—Taxation of Dividends” below, could be affected byactions taken by parties through whom the ADSs are released.
ADSs
If a U.S. holder holds ADSs, for U.S. federal income tax purposes, such holder will generally be treated as
the owner of the underlying shares that are represented by such ADSs. Accordingly, deposits or withdrawals ofshares in exchange for ADSs are not subject to U.S. federal income tax.
Taxation of Dividends
Subject to the discussion under “—U.S. Taxation-Passive Foreign Investment Company Rules” below, thegross amount of any distribution received with respect to our shares or ADSs (including amounts withheld to reflect
Japanese withholding taxes), will be taxable as dividends, to the extent paid out of the current or accumulated
earnings and profits (as determined for U.S. federal income tax purposes). The amount of distribution of property
other than cash will be the fair market value of such property on the date of the distribution. Such cash or non-cash
155

income, including withheld taxes, will be includable in a U.S. holder’s gross income as ordinary income on the day
actually or constructively received by such U.S. holder in the case of shares, or by the depositary, in the case of
ADSs. Such dividends received by a U.S. holder will not be eligible for the “dividends-received deduction” allowed
to U.S. corporations in respect of dividends received from other U.S. corporations. To the extent that an amountreceived by a U.S. holder exceeds such holder’s allocable share of our current and accumulated earnings and profits,
such excess will be applied first to reduce such holder’s tax basis in its shares or ADSs, thereby increasing theamount of gain or decreasing the amount of loss recognized on a subsequent disposition of the shares or ADSs.
Then, to the extent such distribution exceeds such U.S. holder’s tax basis, such excess will be treated as capital gain.
However, we do not expect to keep earnings and profits in accordance with U.S. federal income tax principles.
Therefore, U.S. holders should expect that a distribution will generally be treated as a dividend.
The amount of the dividend paid in Japanese yen will be the U.S. dollar value of the Japanese yen payments
received. This value will be determined at the spot Japanese yen/U.S. dollar rate on the date the dividend isreceived by the depositary in the case of U.S. holders of ADSs, or by the shareholder in the case of U.S. holdersof shares, regardless of whether the dividend payment is in fact converted into U.S. dollars at that time. If theJapanese yen received as a dividend are not converted into U.S. dollars on the date of receipt, a U.S. holder will
have basis in such Japanese yen equal to their dollar value on the date of receipt, and any foreign currency gains
or losses resulting from the conversion of the Japanese yen will generally be treated as U.S. source ordinary
income or loss.
The maximum rate of withholding tax on dividends paid to you pursuant to the Treaty is 10%. As discussed
under “—Japanese Taxation” above, if the Japanese statutory rate is lower than the maximum applicable treaty
rate, the Japanese statutory rate will be applicable. If the statutory rate applicable to you is higher than the
maximum Treaty rate, you will be required to properly demonstrate to us and the Japanese tax authorities yourentitlement to the reduced withholding rate under the Treaty. Subject to certain limitations, the Japanese tax
withheld may be creditable against the U.S. holder’s U.S. federal income tax liability or may be claimed as adeduction from the U.S. holder’s federal adjusted gross income provided that the U.S. holder elects to deduct all
foreign taxes paid on the same taxable year. For foreign tax credit limitation purposes, the dividend will beincome from sources outside the United States. The limitation on foreign taxes eligible for credit is calculated
separately with respect to specific classes of income. For this purpose, dividends we pay will generally constitute“passive category income.” Further, in certain circumstances, if a U.S. holder:•

has held shares or ADSs for less than a specified minimum period during which such U.S. holder is notprotected from the risk of loss; or•is obligated to make payments related to the dividends,

such U.S. holder will not be allowed a foreign tax credit for foreign taxes imposed on dividends paid on shares or
ADSs. The rules governing U.S. foreign tax credits are very complex and U.S. holders should consult their tax
advisors regarding the availability of foreign tax credits under their particular circumstances.
With respect to non-corporate U.S. investors, certain dividends received in taxable years beginning before
January 1, 2011 from a qualified foreign corporation may be subject to reduced rates of taxation. A qualified
foreign corporation includes a corporation that is eligible for the benefits of a comprehensive income tax treaty
with the United States which the U.S. Treasury Department determines to be satisfactory for these purposes andwhich includes an exchange of information provision. The U.S. Treasury Department has determined that theTreaty meets these requirements. In addition, it is expected that we will be eligible for the benefits of the Treaty.
A foreign corporation is also treated as a qualified foreign corporation with respect to individuals paid by that
corporation on shares (or ADSs backed by such shares) that are readily tradable on an established securities
market in the United States. United States Treasury Department guidance indicates that our ADSs (which arelisted on the New York Stock Exchange), but not the shares, are readily tradable on an established securities
market in the United States. There can be no assurance that our ADSs will be considered readily tradable on an
established securities market in later years. Non-corporate holders who do not meet a minimum holding period156

requirement during which they are not protected from a risk of loss or that elect to treat the dividend income as“investment income” pursuant to Section 163(d)(4) of the Code will not be eligible for the reduced rates oftaxation. In addition, the rate reduction will not apply to dividends if the recipient of a dividend is obligated tomake related payments with respect to positions in substantially similar or related property. This disallowance
applies even if the minimum holding period has been met. U.S. holders should consult their own tax advisors
regarding the application of the foregoing rules to their particular circumstances.
Taxation of Capital Gains
Subject to the discussion under “—U.S. Taxation-Passive Foreign Investment Company Rules” below, upona sale or other disposition of shares or ADSs, a U.S. holder will recognize gain or loss in an amount equal to thedifference between the U.S. dollar value of the amount realized and the U.S. holder’s tax basis, determined in
U.S. dollars, in such shares or ADSs. Such gain or loss will be capital gain or loss and will be long-term capitalgain or loss if the U.S. holder’s holding period for such shares or ADSs exceeds one year. A U.S. holder’s tax
basis in its shares or ADSs will generally be the cost to the holder of such shares or ADSs. Any such gain or loss
realized by a U.S. holder upon disposal of the shares or ADSs will generally be income or loss from sources
within the United States for foreign tax credit limitation purposes. The deductibility of capital losses is subject tolimitations.
Passive Foreign Investment Company Rules
Based on our projected composition of income and valuation of assets, including goodwill, we do notbelieve that we will be a passive foreign investment company (“PFIC”) for this year and do not expect to become
one in the future, although there can be no assurance in this regard. However, PFIC status is a factual
determination that is made annually. Accordingly, it is possible that we may become a PFIC in the current or any
future taxable year due to changes in valuation or composition of our income or assets. In addition, thisdetermination is based in part upon certain proposed U.S. Treasury regulations that are not yet in effect (the“Proposed Regulations”) and are subject to change in the future. The Proposed Regulations and otheradministrative pronouncements from the Internal Revenue Service (the “IRS”) provide special rules fordetermining the character of income and assets derived in the banking business for purposes of the PFIC rules.
Although we believe we have adopted a reasonable interpretation of the Proposed Regulations and administrative
pronouncements, there can be no assurance that the IRS will follow the same interpretation.
In general, a foreign corporation is considered a PFIC for any taxable year if either:•at least 75% of its gross income is passive income; or•at least 50% of the value of its assets is attributable to assets that produce or are held for the productionof passive income.

The 50% of value test is based on the average of the value of our assets for each quarter during the taxable
year. If we own at least 25% by value of another company’s stock, we will be treated, for purposes of the PFIC
rules, as owning the proportionate share of the assets and receiving our proportionate share of the income of thatcompany.
If we are a PFIC for any taxable year during which a U.S. holder holds shares or ADSs, the U.S. holder will
be subject to special tax rules with respect to any “excess distribution” that the U.S. holder receives and any gain
the U.S. holder realizes from the sale or other disposition (including a pledge) of shares or ADSs. Additionally,
non-corporate U.S. holders will not be eligible for reduced rates of taxation on any dividends received from us intaxable years beginning prior to January 1, 2011, if we are a PFIC in the taxable year in which such dividends arepaid or in the preceding taxable year.
These special tax rules generally will apply even if we cease to be a PFIC in future years. Distributions U.S.
holders receive in a taxable year that are greater than 125% of the average annual distributions they received
157

during the shorter of the three preceding taxable years or their holding period for shares or ADSs will be treatedas excess distributions. Under these special tax rules:•

the excess distribution or gain will be allocated ratably over the U.S. holder’s holding period for sharesor ADSs;•

the amount allocated to the current taxable year, and any taxable year prior to the first taxable year inwhich we were a PFIC, will be treated as ordinary income; and•the amount allocated to each other year will be subject to tax at the highest tax rate in effect for thatyear, and the interest charge generally applicable to underpayments of tax will be imposed on the
resulting tax attributable to each such year.

Alternatively, a U.S. holder could make a mark-to-market election provided that shares or ADSs are
regularly traded on a qualified exchange. Under current law, the mark-to-market election may be available to
U.S. holders of ADSs because the ADSs are listed on the New York Stock Exchange which constitutes aqualified exchange, although there can be no assurance that the ADSs will be “regularly traded” for purposes ofthe mark-to-market election. Under current law, the mark-to-market election may be available to U.S. holders ofshares because the shares are listed on the Tokyo Stock Exchange, which constitutes a qualified exchange,
although there can be no assurance that the shares will be “regularly traded” for purposes of the mark-to-market
election. In addition, a U.S. holder of shares in a PFIC can sometimes avoid the rules described above by electing
to treat the company as a “qualified electing fund” under Section 1295 of the Code. This option is not available to
U.S. holders of shares because we do not intend to comply with the requirements necessary to permit U.S.
Holders to make this election.
If a U.S. holder holds shares or ADSs in any year in which we are classified as a PFIC, such holder would
be required to file IRS Form 8621.
U.S. holders should consult their own tax advisors concerning the determination of our PFIC status and the
U.S. federal income tax consequences of holding shares or ADSs if we are considered a PFIC in any taxable
year.
Information Reporting and Backup Withholding
In general, information reporting requirements will apply to dividends in respect of the shares or ADSs or
the proceeds from the sale, exchange or redemption of the shares or ADSs paid within the United States, and, insome cases, outside of the United States, to you, unless you are an exempt recipient, such as a corporation. In
addition, backup withholding tax may apply to those amounts if you fail to provide an accurate taxpayer
identification number or fail either to report interest and dividends required to be shown on your U.S. federal
income tax returns or make certain certifications. The amount of any backup withholding from a payment to you
will be allowed as a refund or credit against your U.S. federal income tax liability, provided you furnish therequired information to the IRS.
Recently enacted legislation requires certain U.S. holders to report information with respect to theirinvestment in shares not held in an account maintained by a financial institution to the IRS. Investors who fail toreport required information could become subject to substantial penalties. Potential investors are urged to consult
with their own tax advisors regarding the possible implications of this legislation on their investment in shares.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Progress in financial deregulation and internationalization has led to growth in the diversity and complexityof banking operations, exposing financial institutions to various risks, including credit, market operations,information technology, legal, settlement and other risks. We recognize the conducting of operations tailored to
the risks and managing such risks as a key issue relating to overall management. In order to implement ourbusiness strategy while maintaining our financial stability, we maintain comprehensive risk management andcontrol measures. We maintain basic policies for risk management established by our board of directors that are
applicable to the entire Mizuho group. These policies clearly define the kinds of risks to be managed, set forth
the organizational structure and provide for the human resources training necessary for appropriate levels of risk
management. The policies also provide for audits to measure the effectiveness and suitability of the risk
management structure. In line with these basic policies, we maintain various measures to strengthen and enhance
the sophistication of our risk management system. All yen figures and percentages in this item are truncated.
Accordingly, the total of each column of figures may not be equal to the total of the individual items.
Approach to Basel II
The BIS Regulations, the regulations for international standards of the health of banks first implemented in
1992, have been revised in light of developments in risk management methods in order to better reflect the actual
substance of the risks. These amended regulations, known as “Basel II,” focus on three main points. The first is
minimum capital requirements relating to risk which should be maintained by banks, with respect to which thecalculation method for credit risk was changed and operational risk was added. The second includes asupervisory review process with respect to assessment of risks that cannot be fully addressed through minimum
capital requirements alone. The third is market discipline allowing for assessment by the market throughappropriate disclosure. We have obtained the necessary approvals from government authorities on calculation
methods for each type of risk and have been calculating capital adequacy ratios based on Basel II from March 31,
2007, when the Basel II was implemented in Japan. With regard to credit risk, we have been applying the AIRB
approach, the most sophisticated of the three methods provided for by Basel II, from March 31, 2009. In addition,
we have been applying the AMA for the calculation of operational risk from September 30, 2009.
Overview of Risk Management
Risk Management Structure
Each of our subsidiaries adopts appropriate risk management measures for its business based on the size andnature of its risk exposures, while Mizuho Financial Group controls risk management for the Mizuho group as awhole. Mizuho Financial Group regularly receives reports and applications concerning the risk management
situation from our principal banking subsidiaries and other core group companies and gives them appropriate
instructions concerning risk management. Our principal banking subsidiaries and other core group companies
each maintains its own system for managing various types of risk, regularly receiving reports on the status of risk
at their respective subsidiaries, and gives them appropriate instructions concerning risk management.
Basic Approach
We classify our risk exposures according to the various kinds of risk, including credit risk, market risk,
liquidity risk and operational risk, and manage each type of risk according to its characteristics. In addition to
managing each type of risk individually, we have established a risk management structure to identify andevaluate overall risk and, where necessary, to devise appropriate responses to keep risk within limits that aremanagerially acceptable in both qualitative and quantitative terms. In line with the basic policies relating tooverall risk management laid down by Mizuho Financial Group, companies within the Mizuho group identify
risk broadly and take a proactive and sophisticated approach to risk management, including methodologies for
operations that involve exposures to multiple categories of risk such as settlement and trust businesses.

160

Risk Capital Allocation
We endeavor to obtain a clear grasp of the group’s overall risk exposure and have implemented measures tokeep such risks within the group’s financial base in accordance with the risk capital allocation framework. Morespecifically, we allocate risk capital to our principal banking subsidiaries, including their respective subsidiaries,
and other core group companies to control risk within the limits set for each company. We also control risk
within managerially acceptable limits by working to ensure that the overall risk we hold on a consolidated basis
does not exceed shareholders’ equity and other measures of financial strength. To ensure the ongoing financial
health of Mizuho Financial Group, our principal banking subsidiaries and other core group companies, weregularly monitor the manner in which risk capital is being used in order to obtain a proper grasp of the risk
profile within this framework. Reports are also submitted to the board of directors and other committees of eachcompany. Risk capital is allocated to Mizuho Corporate Bank, Mizuho Bank, Mizuho Securities and Mizuho
Trust & Banking by risk category, and is further allocated within their respective business units based on
established frameworks.
Credit Risk Management
We define credit risk as the Mizuho group’s exposure to the risk of losses that may be incurred due to a
decline in, or total loss of, the value of assets (including off-balance-sheet instruments), as a result of
deterioration in obligors’ financial position. We have established the methods and structures necessary forgrasping and managing credit risk, which has become increasingly complex due to financial deregulation,internationalization and the growing sophistication of transactions. Mizuho Financial Group manages credit risk
for the Mizuho group as a whole. More specifically, we have adopted two different but mutually complementary
approaches in credit risk management. The first approach is “credit management,” in which we manage theprocess for each individual transaction and individual obligor from execution until collection, based on ourassessment of the credit quality of the customer. Through this process, we curb losses in the case of a credit
event. The second is “credit portfolio management,” in which we utilize statistical methods to assess the potential
for losses related to credit risk. Through this process, we identify credit risk and respond appropriately.
Credit Risk Management Structure
Credit Risk Management of the Mizuho GroupOur board of directors determines the Mizuho group’s key matters pertaining to credit risk management. In
addition, the portfolio management committee of Mizuho Financial Group discusses and coordinates the basic
policies in connection with credit risk management and matters in connection with overall credit portfolio
management and credit risk monitoring for the Mizuho group. Under the control of the Chief Risk Officer ofMizuho Financial Group, the Risk Management Division and the Credit Risk Management Division jointly
monitor, analyze and submit suggestions concerning credit risk and formulate and execute plans in connection
with basic matters pertaining to credit risk management.
Credit Risk Management at Our Principal Banking Subsidiaries and Other Core Group Companies
Our principal banking subsidiaries and other core group companies manage their credit risk according to thescale and nature of their exposures in line with basic policies set forth by Mizuho Financial Group. The board of
directors of each company determines key matters pertaining to credit risk management. Their respective
business policy committees are responsible for discussing and coordinating overall management of theirindividual credit portfolios and transaction policies towards obligors. The Chief Risk Officer of each principal
banking subsidiary and core group company is responsible for matters relating to planning and implementing
credit risk management. The credit risk management division of each principal banking subsidiary is responsible
for planning and administering credit risk management and conducting credit risk measuring and monitoring, andsuch division regularly presents reports regarding its risk management situation to Mizuho Financial Group. Eachcredit division determines policies and approves/disapproves individual transactions in terms of credit review,161credit management and collection from customers in accordance with the lines of authority set forth by eachprincipal banking subsidiary. In addition, from the standpoint of internal controls, each of our principal banking
subsidiaries has established internal audit divisions that are independent of the business divisions in order toensure appropriate credit risk management.
Individual Credit Management
Our principal banking subsidiaries use a unified credit rating system and credit risk measurement tools toascertain and monitor the status of their portfolios. They are also improving their credit decisions and posttransaction management functions by examining individual transactions from these viewpoints, providing
internal audits and risk management guidance to individual business promotion offices. Mizuho Securities andother core group companies follow credit risk management procedures that suit the characteristics of theirrespective business sectors.
Credit codes
The basic code of conduct for all of our officers and employees engaged in the credit business is set forth inour credit code. Seeking to fulfill the bank’s public and social role, our basic policy for credit business isdetermined in light of fundamental principles focusing on public welfare, safety, growth and profitability.
Internal rating system
One of the most important elements of the risk management infrastructure of our principal banking
subsidiaries is the use of an internal rating system that consists of credit ratings and pool allocations. Credit
ratings consist of obligor ratings which represent the level of credit risk of the obligor, and transaction ratings
which represent the possibility of ultimately incurring losses related to each individual claim by taking into
consideration the nature of any collateral or guarantee and the seniority of the claim. In principle, obligor ratings
apply to all obligors and are subject to regular reviews at least once a year to reflect promptly the fiscal period
end financial results of the obligors, as well as special reviews as required whenever a obligor’s credit standing
changes. This enables our principal banking subsidiaries to monitor both individual obligors and the status of theoverall portfolio in a timely fashion. Because we consider obligor ratings to be an initial phase of the selfassessment process regarding the quality of our loans and off-balance-sheet instruments, such obligor ratings areclosely linked to the obligor classifications and are an integral part of the process for determining the provision
for loan losses and charge-offs in our self-assessment of loans and off-balance-sheet instruments.
Pool allocations are applied to small claims that are less than a specified amount by pooling customers andclaims with similar risk characteristics and assessing and managing the risk for each such pool. We efficiently
manage credit risk and credit screening by dispersing a sufficient number of small claims within each pool. We
generally review the appropriateness and effectiveness of our approach to obligor ratings and pool allocations
once a year in accordance with predetermined procedures.
Self-assessment, provision for loan losses and off-balance-sheet instruments and charge-offs
We conduct self-assessment of assets to ascertain the status of assets both as an integral part of credit risk
management and in preparation for appropriate accounting treatment, including provision for loan losses andoff-balance-sheet instruments and charge-offs. During the process of self-assessment, obligors are categorized
into certain groups taking into consideration their financial condition and their ability to make payments, andcredit ratings are assigned to all obligors, in principle, to reflect the extent of their credit risks. The related assets
are then categorized into certain classes based on the risk of impairment. This process allows us to identify andcontrol the actual quality of assets and determine the appropriate accounting treatment, including provision forloan losses and off-balance-sheet instruments and charge-offs. Specifically, the credit risk management divisionof each of our principal subsidiaries is responsible for the overall control of the self-assessment of assets of the162respective banking subsidiaries, cooperating with the administrative divisions specified for each type of asset,
including loan portfolios and securities, in executing and managing self-assessments.
Credit review
Prevention of new impaired loans through routine credit management is important in maintaining the qualityof our overall loan assets. Credit review involves analysis and screening of each potential transaction within therelevant business division. In case the screening exceeds the authority of the division, the credit division at
headquarters carries out the review. The credit division has specialist departments for different industries,
business sizes and regions, carries out timely and specialized examinations based on the characteristics of thecustomer and its market, and provides appropriate advice to the business division. In addition, in the case ofobligors with low credit ratings and high downside risks, the business division and credit division jointly clarify
their credit policy and in appropriate cases assist obligors at an early stage in working towards credit soundness.
Collection and disposal of impaired loans
With respect to collection and disposal of impaired loans, our specialist unit maintains central control andpursues corporate restructuring or collection efforts, as appropriate, toward taking the impaired loans off-balance.
Specifically, we believe that supporting the restructuring efforts of corporations is an important role for financial
institutions, and we support corporations undergoing restructuring by reviewing business plans, advising on
restructuring methods and utilizing corporate restructuring schemes such as divestitures and mergers andacquisitions, taking advantage of our group-wide resources. These efforts have been steadily producing
satisfactory results. In addition, we work on final disposal of impaired loans efficiently and swiftly by conducting
bulk sales and by utilizing Mizuho Servicing Co., Ltd., our subsidiary that specializes in performing debt
collection services for our group companies.
Portfolio Management
Risk Measurement
We use statistical methods to manage the possibility of losses by measuring the expected average loss for a
one-year risk horizon (“Expected Loss”) , the maximum loss within a certain confidence interval (“credit VaR”).
The difference between expected loss and credit VaR is measured as the credit risk amount (“ Unexpected
Loss”).
In establishing transaction spread guidelines for credit transactions, we aim to ensure an appropriate returnfrom the transaction in light of the level of risk by utilizing credit cost data as a reference. Also, we monitor ourcredit portfolio from various perspectives and set certain limits so that losses incurred through a hypotheticalrealization of the full credit VaR would be within the amount of risk capital and loan loss reserves.
Risk Control Methods
We recognize two types of risk arising from allowing too large a proportion of overall credit risk to beallocated in certain areas. One type is “credit concentration risk,” which stems from granting excessive credit tocertain individual counterparties. The other type is “chain-reaction default risk,” which arises from granting
excessive credit to certain corporate groups, industrial sectors and other groupings. We make appropriate
management to control these risks in line with our specific guidelines for each. The individual risk management
divisions of our principal banking subsidiaries are responsible for monitoring adherence to these guidelines andreporting to their respective business policy committees.
Portfolios of Our Principal Banking Subsidiaries and Certain Other Core Group Companies
Mizuho Bank’s portfolio is diversified among relatively small accounts centered on individuals, domestic
corporations including mainly small and medium-sized enterprises and middle-market corporations, public sector
entities and other customers in Japan. While Mizuho Corporate Bank’s credit portfolio consists primarily of loans163to Japanese public companies and other major Japanese enterprises, it also includes a significant proportion ofloans to overseas corporations, including foreign subsidiaries of Japanese corporations, that are diversified interms of the regions in which the borrowers are located. While retaining the principal features of each of the twobanking subsidiaries’ respective portfolios, we aim to reduce expected losses while simultaneously utilizing
sophisticated financial tools based on which they make strategic acquisitions and sales of assets. While closely
monitoring the potential for unexpected losses, they also aim to raise overall group capital efficiency, boost
profitability and shareholder value, and enhance the sophistication of their credit risk management.
Market and Liquidity Risk Management
We define market risk as the risk of losses incurred by the group due to fluctuations in interest rates, stock
prices and foreign exchange rates. Our definition includes the risk of losses incurred when it becomes impossible
to execute transactions in the market because of market confusion or losses arising from transactions at pricesthat are significantly less favorable than usual. We define liquidity risk as the risk of losses arising from funding
difficulties due to a deterioration in our financial position that makes it difficult for us to raise necessary funds orthat forces us to raise funds at significantly higher interest rates than usual. Mizuho Financial Group manages
market and liquidity risk for the Mizuho group as a whole.

Market Risk Management StructureMarket Risk Management of the Mizuho GroupOur board of directors determines key matters pertaining to market risk management policies. The ALM &market risk management committee of Mizuho Financial Group broadly discusses and coordinates mattersrelating to basic asset and liability management policies, risk planning and market risk management and proposes
responses to emergencies such as sudden market changes. The Chief Risk Officer of Mizuho Financial Group is
responsible for matters relating to market risk management planning and operations.
The Risk Management Division of Mizuho Financial Group is responsible for monitoring market risk,
reports and analyses, proposals, setting limits and guidelines, and formulating and implementing plans relating tomarket risk management. The Risk Management Division assesses and manages the overall market risk of theMizuho group. It also receives reports from our principal banking subsidiaries and other core group companies
on their market risk management that enable it to obtain a solid grasp of the risk situation, submitting reports tothe chief executive officer on a daily basis and to our board of directors and the executive management
committee of Mizuho Financial Group on a regular basis.
To manage market risk, we set limits that correspond to risk capital allocations according to the risk profilesof our principal banking subsidiaries and other core group companies and thereby prevent market risk fromexceeding our ability to withstand losses based on our financial strength represented by capital, etc. The amountof risk capital allocated to market risk corresponds to VaR and additional costs that may arise in order to close
relevant positions. For trading and banking activities, we set limits for VaR and for losses. For banking activities,
we set position limits based on interest rate sensitivity as needed.
These limits are discussed and coordinated by the ALM & market risk management committee, discussed
further by the executive management committee, then determined by the chief executive officer. Various factors
are taken into account including business strategies, historical limit usage ratios, risk-bearing capacity (profits,
total capital and risk management systems), profit targets and the market liquidity of the products involved.
Market Risk Management at Our Principal Banking Subsidiaries and Other Core Group Companies
Our principal banking subsidiaries and Mizuho Securities which account for most of the Mizuho group’s
exposure to market risk have formulated their basic policies in line with the basic policies determined by Mizuho
Financial Group. Their boards of directors determine important matters relating to market risk management while
their chief executive officers are responsible for controlling market risk. Their respective business policy
committees, including their ALM & market risk management committees, are responsible for overall discussion
and coordination of market risk management. Specifically, these committees discuss and coordinate mattersrelating to basic asset and liability management policies, risk planning and market risk management and propose
responses to emergencies such as sudden market changes. The Chief Risk Officer of each subsidiary is
responsible for matters pertaining to planning and implementing market risk management. Based on a common
Mizuho group risk capital allocation framework, the above-mentioned companies manage market risk by setting
limits according to the risk capital allocated to market risk by Mizuho Financial Group.
These companies have established specialized company-wide market risk management divisions to provide
integrated monitoring of market risk, submit reports, analyses and proposals, set limits and formulate andimplement plans relating to market risk management. The risk management divisions of each company submit
reports on the status of market risk management to their respective chief executive officers and top management
on a daily basis, and to their board of directors and executive management committee on a regular basis. They
also provide regular reports to Mizuho Financial Group. To provide a system of mutual checks and balances inmarket operations, they have established middle offices specializing in risk management that are independent of
their front offices, which engage in market transactions, and their back offices, which are responsible for bookentries and settlements. When VaR is not adequate to control risk, the middle offices manage risk using165

additional risk indices, carry out stress tests and set stop loss limits as needed. They monitor their market
liquidity risk for individual financial products in the market while taking turnover and other factors into
consideration.
Liquidity Risk Management Structure
Liquidity Risk Management of the Mizuho Group
Our liquidity risk management structure is generally the same as the market risk management structure
described above. However, the head of the Financial Control & Accounting Group of Mizuho Financial Group isadditionally responsible for matters relating to planning and running cash flow management operations, while the
Financial Planning Division is responsible for monitoring and adjusting the cash flow management situation andfor planning and implementing cash flow management. Reports on the cash flow situation are submitted to the
ALM & market risk management committee, the executive management committee and the chief executive
officer.
We measure liquidity risk using indices pertaining to cash flow, such as limits on funds raised in the market.
Limits on liquidity risk are discussed and coordinated by the ALM & market risk management committee,
discussed further by the executive management committee and determined by the chief executive officer. We
have established classifications for the cash flow conditions affecting the group, ranging from “normal” to “cause
for concern” and “critical,” and have established procedures for dealing with cases which are deemed to fall into
the “cause for concern” or “critical” categories. In addition, we have constructed a system under which we will
be able to respond smoothly in the event of emergency situations that affect our funding by establishing actionplans.
Liquidity Risk Management at Our Principal Banking Subsidiaries and Other Core Group Companies
The liquidity risk management structures of Mizuho Corporate Bank, Mizuho Bank, Mizuho Trust &Banking and Mizuho Securities are generally the same as the aforementioned market risk management structures,
but the senior executives responsible for risk management are responsible for matters pertaining to planning andconducting liquidity risk management, while the senior executives of the asset and liability management andtrading units are responsible for matters pertaining to planning and conducting cash flow management.
The methodologies used for ensuring precise control of liquidity risk include the formulation ofmanagement indices pertaining to cash flow, such as limits on funds raised in the market. As with Mizuho
Financial Group, the above-mentioned companies have established classifications for the cash flow affecting
them, ranging from “normal” to “cause for concern” and “critical,” and have established procedures for cases
which are deemed to fall into the “cause for concern” or “critical” categories.
Each subsidiary has adopted stringent controls that call for the submission of reports on liquidity risk
management and cash flow management to the ALM & market risk management committee and other business
policy committees, the executive management committee and the chief executive officer of each subsidiary.

Back Testing and Stress Testing
In order to evaluate the effectiveness of market risk measurements calculated using the value-at-risk
method, we carry out regular back tests to compare value-at-risk with assumptive profits and losses. Assumptive
profits and losses accounts for general market risk. The graph below shows daily value-at-risk of trading
activities for the fiscal year ended March 31, 2010, and the corresponding paired distribution of profits andlosses:Back Testing for the fiscal year ended March 31, 2010

VaR (billions of yen)

We had no case where profits/losses exceeded value-at-risk during the period.
Because the value-at-risk method is based on statistical assumptions, we conduct stress testing to simulate
the levels of losses that could be incurred in cases where the market moves suddenly to levels that exceed theseassumptions. The stress testing methods we use include the calculation of losses on the basis of the largest
fluctuations occurring over a period of more than five years and the calculation of losses based on market
fluctuations occurring during historical market events. In addition, we conduct stress testing based on a sharp
drop in the price of securitization and other products due to diminished market liquidity. The table below shows
the assumed maximum loss results of stress testing in trading activities using the methods described above:

Outlier Criteria
As part of the new capital adequacy requirements under Basel II, the losses arising from a banking book in
hypothetical interest rate shock scenarios under certain stress conditions are calculated and compared with thesum of Tier 1 and Tier 2 capital. If the interest rate risk of the banking book leads to an economic value declineof more than 20% of the sum of Tier 1 and Tier 2 capital, we will be deemed an “outlier” and may be required toreduce the banking book risk or adopt other responses. We measure losses arising from our banking book eachmonth as a part of our stress tests.
167

The table below shows the results of calculations of losses in the banking book in cases where interest rate
fluctuations occur under stress conditions. The results of calculations of losses in the banking book show thatthey are 8.8% of broadly-defined capital. Because the amount of risk on the banking book is therefore well underthe 20% threshold and within controllable limits, we do not fall under the “outlier” category. The loss ratio tocapital increased from the previous fiscal year due mainly to the expansion of interest rate risk related to the U.S.
dollar for the fiscal year ended March 31, 2010.

Notes:(1) In the above results of calculations of losses, a part of demand deposits without fixed intervals for amending
applicable interest rates is deemed core deposits and is treated accordingly in the calculation.
(2) For the interest rate shock scenario used in connection with the above figures, we generate annual rate
fluctuation data for five years derived from daily raw historical interest rate data of the past six years andthen apply the actual fluctuation data, which show a rise in interest rates, at a 99.0% confidence level to theshock scenario.
Value-at-Risk
We use the value-at-risk (the “VaR”) method, supplemented with stress testing, as our principal tool tomeasure market risk. The VaR method measures the maximum possible loss that could be incurred due to market
movements within a certain time period (or holding period) and degree of probability (or confidence interval).
Trading Activities
VaR related to our trading activities is based on the following:•

variance co-variance model for linear risk and Monte-Carlo simulation for non-linear risk;•

confidence interval: one-tailed 99.0%;•

holding period of one day; and•historical observation period of one year.

The following tables show the VaR related to our trading activities by risk category for the fiscal years
ended March 31, 2008, 2009 and 2010 and as of March 31, 2008, 2009 and 2010:

VaR is a commonly used market risk management technique. However, VaR models have the following
shortcomings:•

By its nature as a statistical approach, VaR estimates possible losses over a certain period at a particularconfidence level using past market movement data. Past market movement, however, is not necessarily
a good indicator of future events, particularly potential future events that are extreme in nature.

•

VaR may underestimate the probability of extreme market movements.

•

The use of a 99.0% confidence level does not take account of, nor makes any statement about, any
losses that might occur beyond this confidence level.

•

VaR does not capture all complex effects of various risk factors on the value of positions and portfolios
and could underestimate potential losses.

170

We also conduct interest sensitivity analyses of interest risk, our main source of market risk. The following
table shows sensitivity to yen interest risk in our banking activities as of the dates indicated. As shown in thetable, we have reduced overall sensitivity to the risk of future increases in interest rates. Interest rate sensitivity(10 BPV) shows how much net present value varies when interest rates rise by 10 basis (0.1%), and it explains
the impact of interest rate movements on net present value when short- and long-term interest rates behave
differently.

Market Risk Equivalent
In order to calculate the amount of capital necessary to meet the capital requirements relating to market risk(the “market risk equivalent”), we apply internal models to calculate general market risk (risks related to factorsthat apply generally to the market, e.g., interest rates, foreign exchange rates) and the standardized measurement
method to calculate specific risks (risks other than general market risk, e.g., credit quality and market liquidity of
an individual security or instrument). In addition, our internal models are applied to trading transactions withmarket liquidity based on the relevant holding period. Under the internal models, the market risk equivalent iscalculated by taking the greater of (i) VaR on the calculation date and (ii) the average VaR for the preceding 60
business days (including the calculation date) multiplied by a multiplication factor ranging from 3.00 to 4.00 thatis determined based on the number of times VaR is exceeded upon back testing.
The following table shows total market risk equivalent as of the dates indicated calculated using thestandardized measurement method and internal models:

Operational Risk Management
We define operational risk as the risk of loss that we may incur resulting from inadequate or failed internal
processes, people and systems or from external events. We recognize that operational risk includes information
technology risk, operations risk, legal risk, human resources risk, tangible asset risk, regulatory change risk andreputational risk. We have determined risk management policies concerning risk management structures andmethods for each kind of risk. Mizuho Corporate Bank, Mizuho Bank, Mizuho Trust & Banking, Mizuho
Securities, Mizuho Investors Securities and Trust & Custody Services Bank respectively manage operational riskin an appropriate manner pursuant to risk management policies determined by Mizuho Financial Group.
Mizuho Financial Group, Mizuho Corporate Bank, Mizuho Bank, Mizuho Trust & Banking, Mizuho
Securities, Mizuho Investors Securities and Trust & Custody Services Bank share common rules for data
gathering, and we measure operational risk on a regular basis, taking into account possible future loss events andthe changes in the business environment and internal management.
We have established and are strengthening management methods and systems to appropriately identify,
assess, measure, monitor and control the operational risks which arise from the growing sophistication anddiversification of financial operations and developments relating to information technology by utilizing control
self-assessments and improving measurement methods.
Definition of Risks and Risk Management Methods
As shown in the table below, we have defined each component of operational risk and we apply appropriate
risk management methods in accordance with the scale and nature of each risk.

Measurement of operational risk equivalent
Implementation of the AMA
We have been implementing the AMA from September 30, 2009, in place of the gross profit allocation
approach (The Standardized Approach (TSA)) that we had been using previously, for the calculation ofoperational risk equivalent in association with capital adequacy ratios based on Basel II. However, we use the
Basic Indicator Approach (BIA) for entities that are deemed to be less important in the measurement ofoperational risk equivalent and for entities that are preparing to implement the AMA. The measurement results
under the AMA are used not only as the operational risk equivalent in the calculation of capital adequacy ratios
but also as Operational VAR for internal risk management purposes for implementing action plans to reduce
operational risk, etc.
Outline of the AMA•

Outline of measurement system
We have established the model by taking account of four elements: internal loss data; external loss data;
scenario analysis and business environment; and internal control factors (BEICFs). A statistical
approach (one year holding period / one-tailed 99.9 percentile confidence interval) is taken for the
calculation of operational risk equivalent, employing both internal loss data (i.e., actually experienced
operational loss events) and scenario data to reflect unexperienced potential future loss events in themeasurement.
In the measurement of operational risk equivalent as of March 31, 2010, we did not exclude expected
losses and also did not recognize the risk mitigating impact of insurance. In addition, we did not take
into account the events related to credit risk in measuring operational risk equivalent.

•

Outline of measurement model
Operational risk equivalent is calculated as a simple sum of those related to the seven loss event types
defined by Basel II, large-scale natural disasters and litigation. In the measurement of operational risk
equivalent as of March 31, 2010, we did not reflect the correlation effects among operational risk related
to each of the seven loss event types.

•

Operational risk by the loss event type
Loss Distribution (Compound Poisson Distribution) Approach (LDA) is adopted for the calculation ofoperational risk. LDA is based on the assumption that Poisson Distribution applies to the occurrence
frequency of operational risk events, and loss severity is expressed through a separate distribution.
Operational risk is calculated for each of the seven loss event types employing both internal loss data,
based on our actual experience as operational loss events and scenario data. Scenario data, expressed as
numerical values of occurrence frequency and loss severity, reflects external loss data and BEICFs, inorder to estimate unexperienced potential future loss events (of low frequency and high severity).
“Frequency Distribution” and “Severity Distribution” are estimated employing the above mentioned
internal loss data and scenario data, and Monte-Carlo simulations are then applied to these distributions
to measure operational risk. The detailed steps of creation of scenario data are explained later in “(3)Scenario Analysis.”•

Estimation of “Frequency Distribution” and “Loss Severity Distribution”“Frequency Distribution” is estimated by applying information on occurrence frequency of both internal
loss data and scenario data to Poisson Distribution. “Loss Severity Distribution” is generated as theresult of combining, through a statistical approach (Extreme Value Theory), of the actual distribution forthe low severity distribution portion created by internal loss data and another loss distribution (Lognormal Distribution or Generalized Pareto Distribution) for the high severity distribution portion createdby scenario data.
174

•

Operational risk of large-scale natural disasters
Monte-Carlo simulation is applied to the datasets expressed as a combination of the probability ofoccurrence of large-scale natural disasters and the probable loss amount in case of such occurrence, as
opposed to estimating “Frequency Distribution” and “Loss Severity Distribution.”•

Operational risk of litigation
Each litigation is converted into data according to the profile of the individual litigation to which
Monte-Carlo simulation is applied, as opposed to estimating “Frequency Distribution” and “LossSeverity Distribution.” In the measurement process, we assume that final decisions will be made on all
litigation within one year.

•

Verification
We confirm the appropriateness of the measurement model by verifying it, in principle, semi-annually.

Scenario analysis•

Outline of scenario analysis
In the process of scenario analysis, scenario data is created as numerical values of occurrence frequency
and loss severity reflecting external loss data and BEICFs, in order to estimate unexperienced potential
future operational risk events (of low frequency and high severity).
As for external loss data, we refer to data publicly reported by domestic and overseas media, and suchdata are reflected in the estimation of occurrence frequency and loss severity distribution in the processof scenario analysis. In addition, BEICFs are utilized as indices to adjust occurrence frequency and loss
severity distribution in the process of scenario analysis.
We categorize scenario analyses into four approaches in accordance with the characteristics of each loss
event type and risk management structures.
Approach

Loss event type(s) to be applied

A

Internal fraud / External fraud / Clients, products and business practices/ Execution, delivery and process management
Employment practices and workplace safety
Damage to physical assets
Business disruption and system failure

BCD

At Mizuho Financial Group, loss event types to which Approach A is applied account for a considerable
amount of operational risk. The detailed process of Approach A is explained below as a typical exampleof scenario analysis.
•

Setting units for scenario analysis
In order to ensure completeness and sufficiency, we set units that are commonly applied across group
entities that adopt AMA (the “Group Entities”) by referencing and categorizing risk scenarios
recognized through control self-assessment, internal loss data of the Group Entities and external loss
data, etc. Then each of the Group Entities selects the unit on which scenario analysis is conducted fromthe units established on a groupwide basis in accordance with its business activities and operational risk
profile.

•Estimation of occurrence frequency
Basic occurrence frequency (once a year) is calculated for each scenario analysis unit. If a certain
scenario analysis unit has relative internal loss data of a pre-determined threshold amount or above, its
basic occurrence frequency is calculated based on such data, and if not, the basic occurrence frequency175

(the occurrence frequency per year of losses at or above a pre-determined threshold) is calculated withreference to the situation of occurrence of internal loss data of less than the threshold amount and/or
external loss data. The basic occurrence frequency is then adjusted within a pre-determined range for the
purpose of reflecting the most recent BEICF to determine the final occurrence frequency.
•

Estimation of loss severity distribution
In order to estimate loss severity distribution, we use a pre-determined series of severity ranges. Basicloss severity distribution is calculated for each scenario analysis unit as an occurrence ratio (inpercentile figures) of loss at each severity range when losses at or above a pre-determined thresholdoccurred, with reference to transaction amount data, external loss data, etc. Then the basic severity
distribution is adjusted, if necessary, from the viewpoint of statistical data processing to determine thefinal loss severity distribution.

•

Creation of scenario data
For each scenario analysis unit, scenario data is generated as a series of combinations of occurrence
frequency per year at each severity range, based on the final occurrence frequency and the final loss
severity distribution.

Certification of Information Security Management System
Mizuho Financial Group obtained certifications for the Information Security Management Systems of alldivisions of the company under both the Conformity Assessment Scheme, “ISO/IEC27001: 2005,” theinternational standard, and “JIS Q 27001: 2006,” the domestic standard. Mizuho Bank also obtained the same
certifications for its “Planning, promotion and sales supporting divisions of financial products and services forindividuals, corporate and public sector customers” of the head office. Mizuho Financial Group, as the holding
company for the Mizuho group, is responsible for the planning, design and promotion of information security
management of its group companies and has implemented various measures to enhance our management of
information security, including protection of personal information. Mizuho Financial Group will encourage its
other group companies to obtain similar certifications and will continue to make efforts to further strengthen
information security management of the entire group.
Compliance
As one of Japan’s leading comprehensive financial groups, we remain conscious of the importance of oursocial responsibilities and public mission at all times. We define compliance as “the strict observance of all laws
and regulations and the pursuit of fair and honest corporate activities that conform to the norms accepted bysociety” and view ongoing compliance as one of the basic principles of sound business management. Each of ourgroup companies maintains its own compliance structure in line with the basic policies established by Mizuho
Financial Group.
Compliance Structure
The chief executive officer of Mizuho Financial Group, Mizuho Corporate Bank and Mizuho Bank eachgenerally oversees compliance matters of the respective company, and such chief executive officers also head
their respective compliance committees at which important matters concerning compliance are discussed. The
three companies also have individual compliance divisions under a chief compliance officer. These divisions are
responsible for compliance planning and implementation and control overall compliance management at therespective companies. At the level of each organizational unit (such as branches and divisions) at the threecompanies, the head of the unit is responsible for guidance and implementation related to compliance matterswithin such unit, and the compliance officer or the compliance administrator at each unit reviews the status ofcompliance.
Other core group companies such as Mizuho Trust & Banking and Mizuho Securities have also establishedcompliance structures adapted to the characteristics of their respective businesses.
176

Mizuho Financial Group monitors the status of compliance of the Mizuho group through reports submitted
by our principal banking subsidiaries and other core group companies and adopts appropriate responses whennecessary.
Compliance at subsidiaries of our principal banking subsidiaries and other core group companies ismonitored and managed by their respective parent.
Compliance Activities
We have established the “Mizuho Code of Conduct,” which sets forth clear and concrete standards of ethicalbehavior, and distributed it to all directors, senior management and employees of the Mizuho group so that they
are well aware of its content and act accordingly.
Each of our group companies has also prepared a compliance manual, which serves as a practical guidebook
for rigorous compliance enforcement and clarifies the laws and regulations that the group companies mustobserve in pursuing their business activities and the compliance activities they are required to follow.
We conduct compliance training for directors, senior management and employees so that they are fullyacquainted with the contents of the manual. We monitor the status of compliance levels through self assessments
conducted by individual organizational units and monitoring conducted by the compliance division of eachcompany.
Every fiscal year, each of our group companies establishes a compliance program, which contains concretemeasures for compliance enforcement such as measures related to the management of the complianceframework, training and assessments. Progress regarding the implementation of the compliance program ismonitored every six months.
Internal Audit
Internal audits are designed as an integrated process, independent from other business operations, forevaluating the extent to which internal control achieves its objectives in key areas, including appropriate risk
management, efficient and effective business operations, reliable financial reporting and compliance with laws,
regulations and internal rules. We conduct internal audits from an objective and comprehensive standpoint,
independent of operational reporting lines, and offer advice and remedial recommendations in connection withany problems that may be identified. Through this process, internal audits assist the boards of directors of each of
our group companies to fulfill their managerial duties efficiently and effectively.
In line with the Basic Policy for Internal Audit established by Mizuho Financial Group, our principal
banking subsidiaries and other core group companies conduct internal audits, which include the auditing of theirrespective subsidiaries. In addition, with respect to the management of risks applicable across the Mizuho group,
we coordinate internal audits throughout the group to assess the risk management status of the group as a whole.
Internal Audit Management Structure
Mizuho Financial Group
Our internal audit committee determines all important matters concerning internal audits. The committee ischaired by our president and chief executive officer and is independent of our other business operations.
Our internal audit committee monitors and manages internal audits at our principal banking subsidiaries andother core group companies through internal audit reports submitted by such subsidiaries. Our internal audit
committee discusses and makes decisions regarding internal audits at our principal banking subsidiaries and othercore group companies and submits the results, together with the results of their examination of the internal audit
reports, to our board of directors.
177

Mizuho Corporate Bank and Mizuho Bank
Mizuho Corporate Bank and Mizuho Bank have also established internal audit committees that are
independent of their other business operations.
Mizuho Corporate Bank and Mizuho Bank have established internal audit divisions and credit review
divisions to conduct internal audits at their respective domestic and overseas business offices, head officedivisions and group companies. Specifically, the internal audit divisions assess the suitability and effectiveness ofbusiness activities associated with compliance and risk management. The credit review divisions audit credit
ratings and the status of credit management in addition to auditing the self-assessment of assets to verify theaccuracy and suitability of matters deemed necessary to assure the soundness of assets.
Other Core Group Companies
Mizuho Trust & Banking, Mizuho Securities and our other core group companies have also establishedeffective and efficient internal audit structures adapted to the characteristics of their respective businesses.

CONTROLS AND PROCEDURES

Disclosure Controls and Procedures
We carried out an evaluation under the supervision and with the participation of our management, including
our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of ourdisclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934) asof March 31, 2010. There are inherent limitations to the effectiveness of any system of disclosure controls andprocedures, including the possibility of human error and the circumvention or overriding of the controls andprocedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable, notabsolute, assurance of achieving their control objectives. Also, projections of any evaluation of effectiveness tofuture periods are subject to the risk that controls may become inadequate because of changes in conditions, orthat the degree of compliance with the policies or procedures may deteriorate. Based upon the evaluation referred
to above, our Chief Executive Officer and Chief Financial Officer concluded that the design and operation of ourdisclosure controls and procedures as of March 31, 2010 were effective to provide reasonable assurance that
information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded,
processed, summarized and reported within the time periods specified in the SEC’s rules and forms.
Management’s Annual Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial
reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934. Our internal control overfinancial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting andthe preparation of financial statements for external purposes in accordance with applicable generally accepted
accounting principles. Our internal control over financial reporting includes those policies and procedures that:(i)pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect thetransactions and dispositions of our assets;(ii)

provide reasonable assurance that transactions are recorded as necessary to permit preparation offinancial statements in accordance with generally accepted accounting principles, and that ourreceipts and expenditures are being made only in accordance with authorizations of management anddirectors; and(iii)

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition,use or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with thepolicies or procedures may deteriorate.
Our management evaluated the effectiveness of our internal control over financial reporting as of March 31,
2010 based on the criteria established in “Internal Control—Integrated Framework” issued by the Committee ofSponsoring Organizations of the Treadway Commission (COSO). Based on the evaluation, management has
concluded that we maintained effective internal control over financial reporting as of March 31, 2010.

181Pre-Approval Policies and Procedures
We established the pre-approval policies and procedures required by the Sarbanes-Oxley Act on April 1,
2006. Under the procedures, Mizuho Financial Group and its subsidiaries must apply to our corporate auditors
for pre-approval before entering into an agreement regarding audit and permitted non-audit services with E&Y.
We follow two types of pre-approval policies and procedures:
General pre-approval . . . . . . . . . . . . . . . .

General pre-approval is required for services which are
expected to be performed during a given fiscal year. Ourboard of corporate auditors reviews the fees for eachservice and the maximum amount of aggregate fees that
may be incurred and authorizes pre-approval at the
beginning of each fiscal year.

Specific pre-approval . . . . . . . . . . . . . . .

For those services which have not been approved pursuant
to the general pre-approval procedure, specific preapproval by our corporate auditors is required prior toeach engagement. With respect to such services, two fulltime corporate auditors must provide pre-approval andreport such pre-approval at the monthly meeting of theboard of corporate auditors.

ITEM 16D. EXEMPTIONS FROM THE LISTING STANDARDS FOR AUDIT COMMITTEES
Mizuho Financial Group does not have an audit committee. We are relying on the general exemption
contained in Rule 10A-3(c)(3) under the Exchange Act, which provides an exemption from the NYSE’s listing
standards relating to audit committees for foreign companies that have a board of corporate auditors that meet therequirements set forth in Rule 10A-3(c)(3). Our reliance on Rule 10A-3(c)(3) does not, in our opinion, materiallyadversely affect the ability of our board of corporate auditors to act independently and to satisfy the otherrequirements of Rule 10A-3.

None.
ITEM 16G. CORPORATE GOVERNANCE
Our corporate governance practices are governed by applicable Japanese law, specifically the Company
Law and Financial Instruments and Exchange Law of Japan, and our Articles of Incorporation. Also, because ourshares are registered with the U.S. Securities and Exchange Commission and are listed on the New York Stock
Exchange (“NYSE”), we are subject to corporate governance requirements applicable to NYSE-listed foreign
private issuers. NYSE-listed companies that are foreign private issuers meeting certain criteria are permitted tofollow home country practices in lieu of certain provision of Section 303A, and we are relying on this exemption.

183

A NYSE-listed foreign private issuer is required to provide to its US investors, a brief, general summary of
the significant differences of corporate governance practices that differ from US companies under NYSE listing
standards. The following is a summary of the significant ways in which our corporate governance practices differ
from NYSE standards followed by U.S. companies:•

A NYSE-listed U.S. company is required to have a majority of directors, and an audit committee
composed entirely of directors, that meet the independence requirements under Section 303A of the
NYSE’s Listed Company Manual. Under the Japanese Company Law, we are required to have a
corporate governance system based on either (i) a board of corporate auditors or (ii) committees. We
adopt a corporate governance system based on a board of corporate auditors. The basic function of theboard of corporate auditors is similar to that of independent directors, including those who are membersof the audit committee, of a NYSE-listed U.S. company, i.e., to monitor the performance of the directors
and review and express opinions on the method of auditing by the independent public accounting firmand on such accounting firm’s audit reports for the protection of the company’s shareholders. Under theCompany Law, we are required to have at least half of our corporate auditors be outside corporate
auditors who meet the independence requirements under the Company Law. Currently, three of our fivecorporate auditors are outside corporate auditors who meet such independence requirements. In
addition, none of the corporate auditors may at the same time be directors, managers or employees of
the company or any subsidiaries, or accounting participants or executive officers of such subsidiaries.
While the Company Law does not require corporate auditors to have expertise in accounting or otherspecial knowledge and experience, one of our corporate auditors is a certified public accountant. We
rely on an exemption from the audit committee requirements imposed by Rule 10A-3 of the U.S.
Securities Exchange Act of 1934, as amended, which is available to foreign private issuers with a boardof auditors (or similar body) meeting specified criteria. With respect to our board of corporate auditors,
the criteria that we meet include the following:•

responsible, to the extent permitted by law, for the appointment, retention and supervision of thework of a registered public accounting firm engaged for the purpose of preparing or issuing an audit
report or performing other audit, review or attestation services for us;•

subject to procedures for the receipt, retention and treatment of complaints and the confidential,
anonymous submission of concerns by employees regarding the status of our internal control systemon accounting and financial reporting and internal and external audits;•each corporate auditor has the authority to engage independent counsel and other advisers if suchengagement is necessary to carry out his or her duties; and•each corporate auditor has the ability to require us to pay any and all expenses necessary forcarrying out his or her duties.

Under the Company Law, companies that adopt a corporate governance system based on a board ofcorporate auditors, such as us, are note required to maintain directors that are outside directors who meetthe independence requirements under the Company Law. However, three of our nine directors areoutside directors who meet such requirements.
•

A NYSE-listed U.S. company is required to have a nominating/corporate governance committee and acompensation committee, all of which must be composed entirely of independent directors. While we, acompany that has corporate auditors, are not required to establish a nominating committee or acompensation committee under Japanese law, we voluntarily established similar committees, each withsix members, three of which are outside directors, to advise the board of directors on these matters inorder to ensure transparency and impartiality in matters of personnel decisions affecting the board of
directors and directors’ compensation.

•

A NYSE-listed U.S. company must hold regularly scheduled executive sessions where participants arelimited to non-management directors. Under the Company Law, Japanese corporations are not obliged
to hold executive sessions where participants are limited to non-management directors.

•

The Company Law of Japan requires that the aggregate amount of remuneration to be paid to all
directors and the aggregate amount of remuneration to be paid to all corporate auditors to be determinedby a resolution of a general meeting of shareholders, unless their remuneration is provided for in thearticles of incorporation. Such remuneration includes bonuses, retirement allowances and incentive
stock options. Based on the above resolution, the distribution of remuneration among directors is
broadly delegated to our board of directors, which takes into consideration of the advisory opinion by
the compensation committee, and the distribution of remuneration among corporate auditors isdetermined by consultation among our corporate auditors.

•

A NYSE-listed U.S. company must adopt a code of business conduct and ethics and must post the codeon its website. While we are not required to adopt such code under Japanese law or the rules of stock
exchanges in Japan on which we are listed, we maintain the “Mizuho Code of Conduct” as our standard
for corporate conduct to be observed by our directors, officers and employees.

SELECTED STATISTICAL DATA
In preparing the selected statistical data set forth below, foreign activities are defined as business transactions
that involve customers residing outside of Japan. However, as the operations of Mizuho Financial Group, Inc.
and its subsidiaries (“the MHFG Group” or “the Group”) are highly integrated globally, the MHFG Group has
made certain estimates and assumptions in allocating assets, liabilities, income and expense between domestic
and foreign operations. The Group considers domestic and foreign activities determined by such methods to be
representative of the Group’s operations.

I. Distribution of assets, liabilities and equity; interest rates and interest differential
Average balances of balance sheet items, interest and dividend income, interest expense and average yields andrates

income, Interest expense, average yields on interest-earning assets, and average rates on interest-bearing
liabilities for the fiscal years ended March 31, 2008, 2009 and 2010. Average balances are generally based on adaily average. Month-end or quarter-end averages are used for certain average balances where it is notpracticable to obtain applicable daily averages. The average balances determined by such methods are considered
to be representative of the MHFG Group’s operations.

Impaired loans
The MHFG Group considers both loans that are subject to impairment under ASC 310, “Receivables”(“ASC 310)” and small balance, homogenous loans to be impaired when it is probable that the MHFG Group will
be unable to collect all the scheduled payments of principal and interest when due according to the contractual
terms of the loan. Restructured loans and loans that are 90 days or more delinquent are generally considered to be
impaired. All of the MHFG Group’s impaired loans are designated as nonaccrual loans. The following tableshows the distribution of impaired loans at March 31, 2006, 2007, 2008, 2009 and 2010 by domicile and industryof borrower:

The Board of Directors and Shareholders

These financial statements are the responsibility of the Company’s management. Our responsibility is to express
an opinion on these financial statements based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing theaccounting principles used and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated
financial position of Mizuho Financial Group, Inc. and subsidiaries at March 31, 2010 and 2009, and theconsolidated results of their operations and their cash flows for each of the three years in the period ended
March 31, 2010, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board(United States), the Company’s internal control over financial reporting as of March 31, 2010, based on criteria
established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of

Report of Independent Registered Public Accounting Firm
The Board of Directors and Shareholders
of Mizuho Financial Group, Inc.
We have audited Mizuho Financial Group, Inc. and subsidiaries’ (the “Company”) internal control over financial
reporting as of March 31, 2010, based on criteria established in Internal Control—Integrated Framework issued
by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). The
Company’s management is responsible for maintaining effective internal control over financial reporting, and for
its assessment of the effectiveness of internal control over financial reporting included in the accompanying
Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an
opinion on the Company’s internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether effective internal control over financial reporting was maintained in all material respects. Our audit
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on theassessed risk, and performing such other procedures as we considered necessary in the circumstances. We believethat our audit provides a reasonable basis for our opinion.
A company’s internal control over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes inaccordance with generally accepted accounting principles. A company’s internal control over financial reporting
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonableassurance that transactions are recorded as necessary to permit preparation of financial statements in accordancewith generally accepted accounting principles, and that receipts and expenditures of the company are being madeonly in accordance with authorizations of management and directors of the company; and (3) provide reasonableassurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of thecompany’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that

information.
The accompanying consolidated financial statements have been prepared in accordance with the accounting
principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial
statements are stated in Japanese yen, the currency of the country in which MHFG is incorporated and principally
operates.
The accompanying consolidated financial statements include the accounts of MHFG and its subsidiaries. The
consolidated financial statements also include the accounts of the variable interest entities (“VIEs”) for which
MHFG or its subsidiaries have been determined to be the primary beneficiary under the Financial AccountingStandards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, “Consolidation” (“ASC 810”). All
significant intercompany transactions and balances have been eliminated in consolidation. The MHFG Groupaccounts for investments in entities over which it has significant influence using the equity method of
accounting. These investments are included in Other investments and the Group’s proportionate share of income
or loss is included in Investment gains (losses)—net.
Use of estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management tomake estimates and assumptions that affect reported amounts and related disclosures. Specific areas, among
others, requiring the application of management’s estimates and judgment include assumptions pertaining to theallowance for loan losses, allowance for losses on off-balance-sheet instruments, deferred tax assets, derivative
financial instruments, investments and pension and other employee benefits. Actual results could differ fromestimates and assumptions made.
Definition of cash and due from banks
For purposes of the consolidated statements of cash flows, Cash and due from banks include cash on hand, cash
items in the process of collection and noninterest-bearing deposits with banks.
Translation of foreign currency financial statements and foreign currency transactions
Financial statements of overseas entities are prepared using the functional currency of each entity and translated
into Japanese yen for consolidation purposes. Assets and liabilities are translated using the fiscal-year-end
exchange rate of each functional currency, and income and expense using the average rate of each functional
currency for the period.

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Foreign currency translation gains and losses related to the financial statements of overseas entities of the MHFG
Group, net of related income tax effects, are credited or charged directly to Foreign currency translation
adjustments, a component of Accumulated other comprehensive income (loss), net of tax. Tax effects of gains
and losses on foreign currency translation of financial statements of overseas entities are not recognized unless it
is apparent that the temporary differences will reverse in the foreseeable future.
Assets and liabilities denominated in foreign currencies are translated into Japanese yen at the fiscal-year-end
foreign exchange rates, and gains and losses resulting from such translation are included in Foreign exchange
gains (losses)—net, as appropriate. Foreign currency denominated income and expenses are translated using
average exchange rates for the period.
Call loans and call money
Call loans and call money represent lending/borrowing through the Japanese short-term money market to/fromother financial institutions such as banks, insurance companies, and securities brokerage houses.
Repurchase and resale agreements, securities lending and borrowing and other secured financing transactions
Securities sold under agreements to repurchase (“repurchase agreements”), securities purchased underagreements to resell (“resale agreements”) and securities lending and borrowing transactions are accounted for as
secured financing or lending transactions when control over the underlying securities is not deemed to be
surrendered by the transferor. Otherwise, they are recorded as sales of securities with related forward repurchasecommitments or purchases of securities with related forward resale commitments in accordance with ASC 860“Transfers and Servicing” (“ASC 860”).
Under resale agreements, securities borrowing and certain derivatives transactions, the MHFG Group receives
collateral in the form of securities. In many cases, the MHFG Group is permitted to sell or repledge the securities
obtained as collateral. Disclosures of such collateral are presented in Note 10 “Pledged assets and collateral”.
With respect to securities lending, repurchase agreements, and certain derivative transactions, counterparties may
have the right to sell or repledge securities that the MHFG Group has pledged as collateral. The MHFG Groupseparately discloses those pledged securities in the consolidated balance sheets.
The MHFG Group monitors credit exposure arising from resale agreements, repurchase agreements, securities
borrowing and securities lending transactions on a daily basis, and additional collateral is obtained from orreturned to counterparties as appropriate.
Trading securities and trading securities sold, not yet purchased
Trading securities consist of securities and money market instruments that are bought and held principally for the
purpose of reselling in the near term with the objective of generating profits on short-term fluctuations in price.
Trading securities sold, not yet purchased, are securities and money market instruments sold to third parties that
the MHFG Group does not own and is obligated to purchase at a later date to cover the short position. Trading
securities and trading securities sold, not yet purchased, are classified at the date of commitment or purchase.
Trading securities and trading securities sold, not yet purchased, are recorded at fair value in the consolidatedbalance sheets in Trading account assets and Trading account liabilities with realized and unrealized gains andlosses recorded on a trade date basis in Trading account gains—net in earnings. Interest and dividends on trading
account debt and equity securities, including securities sold, not yet purchased, are recorded in Interest anddividend income or Interest expense on an accrual basis.
F-13

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Investments
Debt securities that the MHFG Group has both the positive intent and ability to hold to maturity are classified as
Held-to-maturity securities and carried at amortized cost. Debt securities that the MHFG Group may not hold tomaturity as well as any marketable equity securities, other than those classified as trading account securities, areclassified as Available-for-sale securities, and are carried at fair value, with unrealized gains and losses reported
in Accumulated other comprehensive income (loss), net of tax. Available-for-sale securities also include retained
subordinated beneficial interests in a securitization transaction that can contractually be repaid or otherwise
settled in such a way that the holder would not recover substantially all of its recorded investments.
Prior to April 1, 2009, declines in the fair value of Held-to-maturity and Available-for-sale securities below theiramortized cost, that were deemed to be other-than-temporary, were all reported in Investment gains (losses)—
net. Effective April 1, 2009, the MHFG Group adopted new accounting guidance for impairments of debt
securities that are deemed to be other-than-temporary. Under the new impairment model, the credit component ofan other-than-temporary impairment of a debt security is reported in Investment gains (losses)—net and thenoncredit component is reported in Other comprehensive income (loss). See Note 5 “Investments” for further
discussion of the new impairment model for debt securities. In addition, other-than-temporary declines inbeneficial interests purchased or retained in a securitization transaction which are classified as available-for-saledebt securities are recognized if there has been an adverse change in the cash flows as of the balance sheet date.
Interest and dividends, as well as amortization of premiums and accretion of discounts, are reported in Interestand dividend income. Amortization of premiums and accretion of discounts on debt securities are recognizedover the remaining maturity under the interest method. Gains and losses on disposition of investments arecomputed using the first-in first-out method for debt securities and the average method for equity securities, andare recorded on the trade date.
Other investments include marketable and non-marketable equity securities accounted for using the equity
method, marketable and non-marketable investments held by consolidated investment companies which are heldat fair value under specialized industry accounting principles for investment companies, and othernon-marketable equity securities carried at cost, less other-than-temporary impairment, if any.
Derivative financial instruments
Derivative financial instruments are bought and held principally for the purpose of market making for customers,
proprietary trading in order to generate trading revenues and fee income, and also to manage the MHFG Group’s
exposure to interest rate, credit and market risks related to asset and liability management. Such derivative
financial instruments include interest rate, commodity, foreign currency, equity and credit default swap
agreements, options, caps and floors, and financial futures and forward contracts.
Derivatives bought and held for trading purposes are recorded in the consolidated balance sheets at fair value inTrading account assets and Trading account liabilities. The fair value of derivatives in a gain position and a loss
position are reported as Trading account assets and Trading account liabilities, respectively.
Derivatives used for asset and liability management include contracts that qualify for hedge accounting under
ASC 815, “Derivatives and Hedging” (“ASC 815”). To be eligible for hedge accounting, derivative instruments
must be highly effective in achieving offsetting changes in fair values or variable cash flows from the hedged
items attributable to the particular risk being hedged. All qualifying hedging derivatives are valued at fair value
and included in Trading account assets or Trading account liabilities. Derivatives that do not qualify for hedge
accounting under ASC 815 are treated as trading positions and are accounted for as such. The fair value amounts
recognized for such derivatives are not offset against the amounts recognized for the right to reclaim cash
collateral or the obligation to return cash collateral under master netting agreement with the same counterparty.
F-14

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
The fair value of derivative financial instruments is based on quoted market prices or broker-dealer quotes. If
quoted market prices or broker-dealer quotes are not available, the fair value is estimated using quoted market
prices for similar instruments, option or binomial pricing models or present value cash flow analysis, applying
current observable market information, where available. The determination of fair value includes various factors
such as exchange or over-the-counter market quotes, time value and volatility factors for options and warrants,
observed prices for similar or synthetic instruments, and counterparty credit quality including potential exposure.
Changes in fair value of all derivatives are recorded in earnings, except for derivatives qualifying as net
investment hedges under ASC 815 which are recorded in Accumulated other comprehensive income (loss), net oftax. The fair value changes of all derivatives relating to foreign currency exchange rates are included in Foreignexchange gains (losses)—net. Other elements of the fair value changes, including interest rate, equity and credit
related components except that of certain credit derivatives hedging the credit risk in corporate loan portfolio, arerecognized in Trading account gains—net. The net gain (loss) resulting from changes in the fair values of certain
credit derivatives where the Group purchases protection to mitigate its credit risk exposure related to its corporateloan portfolio is recorded in Other noninterest income (expenses).
Certain financial and hybrid instruments often contain embedded derivative instruments that possess implicit or
explicit contract terms in a manner similar to that of a derivative instrument. Such derivative instruments are
required to be fair-valued separately from the host contracts if they meet the criteria of an embedded derivative.
Such criteria include whether the entire instrument is not marked to market through earnings, the economics ofthe embedded terms are not clearly and closely related to those of the host contract and the embedded terms
would meet the definition of a derivative on a stand-alone basis.
Loans
Loans are generally carried at the principal amount adjusted for unearned income and deferred net nonrefundable
loan fees and costs. Loan origination fees, net of certain direct origination costs are deferred and recognized overthe contractual life of the loan as an adjustment of yield using a method that approximates the interest method.
Interest income on performing loans is accrued and credited to income as it is earned. Unearned income anddiscounts or premiums on purchased loans are deferred and recognized over the life of the loan using a methodthat approximates the interest method.
Loans are considered impaired when, based on current information and events, it is probable that the MHFG
Group will be unable to collect all the scheduled payments of principal and interest when due according to thecontractual terms of the loan. Factors considered by management in determining if a loan is impaired include
delinquency status and the ability of the debtor to make payment of the principal and interest when due.
Loans are designated as nonaccrual when management determines them to be impaired based on all the relevantfacts and circumstances. When a loan is placed on nonaccrual status, interest accrual and amortization of net
origination fees are suspended and the capitalized interest is written off. Cash received on nonaccrual loans isaccounted for as reduction of the loan principal if the ultimate collectibility of the principal amount is uncertain,otherwise, as interest income. Loans are not restored to accrual status until interest and principal payments are
current and future payments are reasonably assured.
Fees received in connection with a modification of the terms of a restructured loan that meet the definition oftroubled debt restructurings in accordance with ASC 310, “Receivables” (“ASC 310”) are applied as a reductionof the recorded investment in the loan. All related costs, including direct loan origination costs, are charged to
expense as incurred.
F-15

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Loans that have been identified to be sold are classified as loans held for sale within Other assets and areaccounted for at the lower of cost or fair value. If management decides to retain certain loans held for sale for theforeseeable future or until maturity or payoff, such items are transferred to Loans at the lower of cost or fairvalue.
Securitization
The MHFG Group engages in securitization activities related to mortgage loans and other loans in the normal
course of business. The MHFG Group records a loan securitization as a sale when the transferred loans arelegally isolated from the Group’s creditors and the accounting criteria for a sale are met in accordance with ASC
860. Otherwise, the transfer is accounted for as a collateralized borrowing. Gains or losses on securitization
depending in part on the carrying amount of the loans are allocated between the loans derecognized and theretained interests based on their relative fair values at the date of the transfer. Interests in loans sold throughsecuritization may be retained by the Group in the form of subordinated beneficial interests. The MHFG Groupestimates fair value of these subordinated beneficial interests based on the present value of future expected cash
flows, using management’s best estimates of the key assumptions, such as default rates, discount rates, andprepayment rates, and records them as available-for-sale debt securities.
Allowance and provision (credit) for loan losses
The MHFG Group maintains an appropriate amount of allowance for loan losses to absorb probable losses
inherent in the loan portfolio and makes adjustments to such allowance through Provision (credit) for loan losses
in the consolidated statements of income. Loan principal which management judges to be uncollectible, based on
detailed loan reviews and a credit quality assessment, is charged off against the allowance for loan losses.
Subsequent recoveries of previously charged-off loan balances are recorded as an increase to the allowance forloan losses as the recoveries are received.
The credit quality review process and the credit rating process serve as the basis for determining the allowance
for loan losses. Through such processes loans are categorized into groups to reflect the probability of default,
whereby the MHFG Group’s management assesses the ability of borrowers to service their debt, taking into
consideration current financial information, ability to generate cash, historical payment experience, analyses of
relevant industry segments and current trends. In determining the appropriate level of the allowance, the MHFG
Group evaluates the probable loss by category of loan based on its risk type and characteristics.
The allowance for loan losses is determined in accordance with ASC 310 and ASC 450, “Contingencies”(“ASC 450”). The MHFG Group measures the impairment of a loan, based on the present value of expected
future cash flows discounted at the loan’s initial effective interest rate, the loan’s observable market price, or thefair value of the collateral if the loan is collateral dependent, when it is probable that the MHFG Group will be
unable to collect all amounts due according to the contractual terms of the loan agreement. Certain impairedloans are aggregated for the purpose of measuring impairment and a formula allowance utilizing historical loss
factors is applied. The formula allowance is also applied to groups of small balance, homogeneous loans that arecollectively evaluated for impairment and for non-homogeneous loans that have not been identified as impaired.
The evaluation of inherent loss for these loans involves a high degree of uncertainty, subjectivity and judgment
because probable loan losses are not easily identifiable or measurable. In determining the formula allowance, theMHFG Group therefore relies on a statistical analysis that incorporates loss rates based on its own historical loss
experience and third party data. The estimation of the formula allowance is back-tested on a periodic basis bycomparing the allowance with the actual results subsequent to the balance sheet date.

F-16

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
The historical loss rate is adjusted, where appropriate, to reflect current factors, such as general economic andbusiness conditions affecting the key lending areas of the MHFG Group, credit quality trends, specific industry
conditions within portfolio segments, and recent loss experience in particular segments of the portfolio.
Allowance and provision (credit) for losses on off-balance-sheet instruments
The MHFG Group maintains an allowance for losses on off-balance-sheet credit instruments, such as guarantees,
standby letters of credit, commitments to invest in securities and commitments to extend credit, in the samemanner as the allowance for loan losses. The allowance is recorded in Other liabilities. Net changes in theallowance for losses on off-balance-sheet instruments are accounted for in the Provision (credit) for losses on
off-balance-sheet instruments in the consolidated statements of income.
Premises and equipment
Premises and equipment are stated at historical cost, and depreciation and amortization are recorded over theestimated useful lives of the assets, except for leasehold improvements, which are amortized over the shorter ofthe estimated useful lives of the assets or the lease term. Depreciation and amortization are principally computed
under the straight-line method with respect to buildings and leasehold improvements and under the decliningbalance method with respect to other premises and equipment.
The useful lives of premises and equipment are as follows:
Years

Buildings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 to 50
Equipment and furniture . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 to 20
Leasehold improvements . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 to 50
Regular repairs and maintenance costs that do not extend the estimated useful life are charged to expense as
incurred. Upon sale or disposition of premises and equipment, the cost and related accumulated depreciation oramortization are removed from the accounts, and any gains or losses on disposal are included in Gains on
disposal of premises and equipment or Occupancy expenses.
Impairment of long-lived assets
The MHFG Group’s long-lived assets that are held for use are reviewed periodically for events or changes incircumstances that indicate possible impairment. The Group’s impairment review is based on an undiscounted
cash flow analysis of a group of assets, combined with associated liabilities, at the lowest level for which
identifiable cash flows exist. Impairment occurs when the carrying value of the asset group exceeds the future
undiscounted cash flows that the asset group is expected to generate. When there is impairment, the future cash
flows are then discounted to determine the estimated fair value of the asset group and an impairment charge isrecorded for the difference between the carrying value and the estimated fair value of the asset group. The longlived assets to be disposed of by sale are carried at the lower of the carrying amount or fair value, less estimatedcost to sell.
Software
Internal and external costs incurred in connection with developing and obtaining software for internal use that
occur during the application development stage are capitalized. Such costs include salaries and benefits for
employees directly involved with and who devote time to the project, to the extent such time is incurred directly
F-17

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
on the internal use software project. The capitalization of software ceases when the software project has been
substantially completed. The capitalized software is amortized on a straight-line basis over the estimated usefullife, generally 5 years. Impairment of internal use software is assessed and recognized periodically when
triggering events occur.
Goodwill
Goodwill represents the excess of the cost of an acquisition over the fair value of the MHFG Group’s share of net
identifiable assets acquired at the date of acquisition in a business combination. The Group accounts for goodwillin accordance with ASC350, “Intangibles—Goodwill and Other” (“ASC 350”). Goodwill is recorded at adesignated reporting unit level for the purpose of assessing impairment. An impairment loss is recorded to theextent the carrying amount of goodwill exceeds its estimated fair value.
Intangible assets
Intangible assets having definite useful lives are amortized over their estimated useful lives under the straightline method. Intangible assets acquired by the merger of MHSC and Shinko Securities Co., Ltd. (“Shinko”)
consist primarily of customer relationship intangibles, and are amortized over a weighted-average amortization
period of 16 years. Intangible assets having indefinite useful lives are not amortized and are subject toimpairment tests. An impairment loss is recorded to the extent the carrying amount of indefinite-lived intangible
asset exceeds its estimated fair value. For intangible assets subject to amortization, an impairment loss isrecorded if the carrying amount is not recoverable and exceeds its estimated fair value.
Pension and other employee benefits
MHFG and certain subsidiaries including MHBK, MHCB, and MHTB sponsor severance indemnities andpension plans, which provide defined benefits to retired employees. Periodic expense and accrued liabilities arecomputed based on the actuarial present value of benefits, net of investment returns expected from plan assets
and their fair values at the balance sheet date. Net periodic expense is charged to Salaries and employee benefits.
Debentures and long-term debt
Premiums, discounts and issuance costs of debentures and long-term debt are amortized based on a method thatapproximates the interest method over the terms of the debentures and long-term debt.
Obligations under guarantees
The MHFG Group provides customers with a variety of guarantees and similar arrangements, including standby
letters of credit, financial and performance guarantees, credit protections, and liquidity facilities. The MHFG
Group recognizes guarantee fees income over the guarantee period. The MHFG Group receives such a guarantee
fee at the inception of the guarantee or by installment, and in either case approximates the fair value of theguarantee.
Fair Value Measurements
The MHFG Group carries certain of its financial assets and liabilities at fair value on a recurring basis. These
financial assets and liabilities are primarily composed of trading account assets, trading account liabilities andavailable-for-sale securities. In addition, the Group measures certain financial assets and liabilities, at fair value
on a non-recurring basis. Those assets and liabilities primarily include items that are measured at the lower ofcost or fair value such as loans held for sale, and items that were initially measured at cost and have been written
down to fair value for impairment such as loans and other investments.
F-18

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderlytransaction between market participants at the measurement date. In accordance with ASC 820, “Fair Value
Measurements and Disclosures” (“ASC 820”), the Group classifies its financial assets and liabilities into the fairvalue hierarchy (Level 1, 2, and 3). See Note 29 “Fair value” for the detailed definition of each level.
When determining fair value, the MHFG Group considers the principal or most advantageous market in which
the Group would transact and consider assumptions that market participants would use when pricing the asset or
liability. The Group maximizes the use of observable inputs and minimizes the use of unobservable inputs whenmeasuring fair value. See Note 29 “Fair value” for descriptions of valuation methodologies used for its assets andliabilities by product.
Fees and commissions
Fee revenue is recognized when all of the following criteria have been met: persuasive evidence of an agreement
exists, services have been rendered, the price is fixed or determinable, and collectibility is reasonably assured.
Trust fees are recognized on an accrual basis and are usually based on the volume of assets under custody or
management. Performance-related fees associated with certain trust products are recognized on an accrual basis.
Fees on funds transfer and collection services are generally recognized as revenue when the related services are
performed. Revenues from investment banking services are recorded at the time the underlying transactions aresubstantially completed and there are no other contingencies associated with the fees. Fees from trade-related
financing services are recognized over the period of the financing.
Fees and commissions are presented on a gross basis.
Income taxes
Income taxes are accounted for in accordance with ASC 740, “Income Taxes” (“ASC 740”). 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 those corresponding amounts used for income tax purposes, and(2) operating loss and tax credit carryforwards. A valuation allowance for any portion of the deferred tax assets isrecorded unless it is more likely than not that the deferred tax assets will be realized. Deferred income tax benefit
or expense is recognized for the changes in the net deferred tax asset or liability between periods.
Earnings per common share
Basic earnings per common share are computed by dividing net income attributable to MHFG commonshareholders by the weighted average number of common shares outstanding during the fiscal year. Diluted
earnings per common share reflect the possible exercise of all convertible securities, such as convertible
preferred stock to the extent they are not anti-dilutive. See Note 20 “Earnings per common share” for thecomputation of basic and diluted earnings per common share.
2. Recently issued accounting pronouncements
Recently adopted accounting pronouncements
On July 1, 2009, the ASC was officially launched. The ASC, which reorganized the thousands of U.S. GAAP
pronouncements into roughly 90 accounting topics, is the single source of authoritative U.S. GAAP for
nongovernmental entities.
In July 2006, the FASB issued FASB Interpretation (“FIN”) No.48, “Accounting for Uncertainty in Income
Taxes”, which is now included in ASC 740. The interpretation creates a single model to address uncertainty in all
F-19

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
tax positions and clarifies the accounting for income taxes by prescribing the minimum recognition threshold atax position is required to meet before being recognized in the financial statements. The interpretation also
provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim
periods, disclosure and transition. The MHFG Group adopted the interpretation as of April 1, 2007, which
resulted in an increase to the beginning balance of Accumulated deficit of ¥2,597 million.
In September 2006, the FASB issued Statement of Financial Accounting Standards (“SFAS”) No.157, “Fair
Value Measurements” which is now included in ASC 820. The statement clarifies the definition of fair value andthe method used to measure fair value and expands the disclosure requirements about fair value measurements.
The statement establishes a fair value hierarchy that distinguishes between (1) market participant assumptions
developed based on market data obtained from sources independent of the reporting entity and (2) the reporting
entity’s own assumptions about market participant assumptions developed based on the best information
available in the circumstances. The statement nullifies certain guidance provided for in the FASB Emerging
Issues Task Force (“EITF”) Issue No.02-3, “Issues Involved in Accounting for Derivative Contracts Held for
Trading Purposes and Contracts Involved in Energy Trading and Risk Management Activities”, and the related
provisions of SFAS No.133. The statement is effective for fiscal years beginning after November 15, 2007. In
February 2008, the FASB issued FASB Staff Position (“FSP”) No.FAS157-1, “Application of FASB Statement
No.157 to FASB Statement No.13 and Other Accounting Pronouncements That Address Fair Value
Measurements for Purposes of Lease Classification or Measurement under Statement 13” and FSP No.FAS157-2,“Effective Date of FASB Statement No.157”, which are now included in ASC 820, and partially delay theeffective date of the statement for one year for certain nonfinancial assets and liabilities and remove certain
leasing transactions from its scope. In October 2008, the FASB issued FSP No. FAS157-3, “Determining the Fair
Value of a Financial Asset When the Market for That Asset Is Not Active”, which is now included in ASC 820,
and clarifies the application of the statement in markets that are not active and provides an example to illustrate
key considerations in determining the fair value of a financial asset when the market for that financial asset is not
active. In April 2009, the FASB issued FSP No.FAS157-4, “Determining Fair Value When the Volume andLevel of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are
Not Orderly”, which is now included in ASC 820, and provides additional guidance for estimating fair value
when the volume and level of activity for the asset or liability have significantly decreased and for identifying
circumstances that indicate a transaction is not orderly, as well as requires detailed disclosures for debt andequity securities. The impact of adoption of the statement was a decrease of ¥1,464 million to the beginningbalance of Accumulated deficit as of April 1, 2008.
In February 2007, the FASB issued SFAS No.159, “The Fair Value Option for Financial Assets and Financial
Liabilities Including an amendment of FASB Statement No.115”, which is now included in ASC 825, “Financial
Instruments” (“ASC 825”). The statement allows entities to choose, at specified election dates, to measureeligible financial assets and liabilities and certain other items at fair value that are not otherwise required to bemeasured at fair value. If a company elects the fair value option for an eligible item, changes in that item’s fairvalue in subsequent reporting periods must be recognized in current earnings. The statement is effective for fiscal
years beginning after November 15, 2007. The financial assets or liabilities for which the MHFG Group elected
the fair value option as of April 1, 2008 are primarily foreign currency denominated available-for-sale securities
and certain hybrid financial instruments that contain embedded derivatives that had not been previously electedor eligible for fair value treatment. The impact of adoption of the statement was a decrease of ¥26,373 million to
the beginning balance of Accumulated deficit as of April 1, 2008.
In April 2007, the FASB issued FSP No.FIN39-1, “Amendment of FASB Interpretation No.39” which is now
included in ASC 815. The pronouncement amends FIN No.39, “Offsetting of Amounts Related to Certain
Contracts—an interpretation of APB Opinion No.10 and FASB Statement No.105”, to permit a reporting entity
to offset fair value amounts recognized for the right to reclaim cash collateral (a receivable) or the obligation to
return cash collateral (a payable) against fair value amounts recognized for derivative instruments executed with
F-20

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
the same counterparty under the same master netting arrangement. The adoption of the pronouncement did nothave an impact on the MHFG Group’s consolidated results of operations or financial condition, as the Group did
not adopt such offsets.
In December 2007, the FASB issued SFAS No.141 (revised 2007), “Business Combinations”, which is now
included in ASC 805, “Business Combinations” (“ASC 805”). The statement establishes principles andrequirements for how the acquirer (1) recognizes and measures in its financial statements the identifiable assets
acquired, the liabilities assumed, and any noncontrolling interests in the acquiree, (2) recognizes and measures
goodwill acquired in the business combination or a gain from a bargain purchase, and (3) determines what
information to disclose to enable users of the financial statements to evaluate the nature and financial effects ofthe business combination. The statement applies prospectively to business combinations for which the acquisition
date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. In
April 2009, the FASB issued FSP No.FAS141(R)-1, “Accounting for Assets Acquired and Liabilities Assumed
in a Business Combination That Arise from Contingencies”, which is now included in ASC 805. The
pronouncement provides the guidance for initial recognition and measurement of all assets acquired andliabilities assumed in a business combination that arise from contingencies as well as subsequent measurement
and accounting of such assets and liabilities. As a result of the transaction discussed in Note 3 “Business

The statement establishes general standards of accounting for and disclosureof events that occur after the balance sheet date but before financial statements are issued or are available to beissued. The statement is effective for interim or annual financial periods ending after June 15, 2009. In February
2010, the FASB issued Accounting Standards Update (“ASU”) No.2010-09, “Subsequent Events (Topic 855)—
Amendments to Certain Recognition and Disclosure Requirements” (“ASU No.2010-09”). The ASU removes therequirement for a U.S. Securities and Exchange Commission (“SEC”) filer to disclose the date through which

condition.
In August 2009, the FASB issued ASU No.2009-05, “Fair Value Measurements and Disclosures (Topic 820)—
Measuring Liabilities at Fair Value” (“ASU No.2009-05”). The ASU provides new guidance clarifying how tomeasure the fair value of liabilities, particularly in circumstances in which a quoted price in an active market for
the identical liability is not available. It also clarifies that a restriction preventing the transfer of a liability should
not be considered as a separate input or adjustment in measurement of the fair value. The ASU is effective for the
first reporting period, including interim periods, beginning after issuance. The adoption of ASU No.2009-05 did
not have a material impact on the MHFG Group’s consolidated results of operations or financial condition.
In September 2009, the FASB issued ASU No.2009-12, “Fair Value Measurements and Disclosures (Topic820)—Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)” (“ASUNo.2009-12”). The ASU permits, as a practical expedient, a reporting entity to measure the fair value of analternative investment on the basis of the net asset value per share (“NAV”), if certain criteria are met. The ASU
only applies to investments that do not have a readily determinable fair value in investment companies or similar
F-23

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
entities. The ASU also provides guidance on the clarification of fair value hierarchy for such investments andrequires enhanced disclosures by each major category of those investments. The ASU is effective for interim andannual reporting periods ending after December 15, 2009. The adoption of ASU No.2009-12 did not have amaterial impact on the MHFG Group’s consolidated results of operations or financial condition.
In January 2010, the FASB issued ASU No.2010-02, “Consolidation (Topic 810)—Accounting and Reporting for
Decreases in Ownership of a Subsidiary—a Scope Clarification” (“ASU No.2010-02”). The ASU amends ASC
810-10 and related guidance within U.S. GAAP to clarify the scope of decreases in ownership. The ASU also
expands disclosure requirements about (1) the valuation techniques used to measure the fair value of retained
investments in the former subsidiary and (2) the nature of continuing involvement and related party relationships.
The ASU is effective beginning in the first interim or annual reporting period ending on or after December 15,
2009 and the amendments should be applied retrospectively to the first period that SFAS No.160 was adopted.
The adoption of ASU No.2010-02 did not have a material impact on the MHFG Group’s consolidated results ofoperations or financial condition.
Accounting pronouncements issued but not yet effective
In June 2007, the American Institute of Certified Public Accountants (“AICPA”) issued Statement of Position(“SOP”) No.07-1, “Clarification of the Scope of the Audit and Accounting Guide Investment Companies andAccounting by Parent Companies and Equity Method Investors for Investments in Investment Companies”,
which is now included in ASC 946, “Financial Services—Investment Companies” (“ASC 946”), and provides
guidance for determining whether an entity is within the scope of the AICPA Audit and Accounting Guide
Investment Companies (“the Guide”). The statement was expected to be effective for fiscal years beginning on orafter December 15, 2007, with earlier application encouraged. However, in February 2008, the FASB issued FSP
No.SOP07-1-1, “Effective Date of AICPA Statement of Position 07-1”, which is now included in ASC 946 as
well, to delay the effective date of SOP No.07-1 indefinitely in order to address implementation issues. The
MHFG Group does not expect that the current form of the statement will have a material impact on its
consolidated results of operations or financial condition.
In June 2009, the FASB issued SFAS No.166, “Accounting for Transfers of Financial Assets—an amendment of
FASB Statement No.140”, which is now included in ASC 860. The statement requires more information abouttransfers of financial assets, including securitization transactions, where enterprises have continuing exposure to
the risks related to the transferred financial assets. The statement eliminates the concept of qualifying SPE andmodifies the requirements for derecognizing financial assets. The statement is effective as of the beginning of thefirst fiscal year that begins after November 15, 2009. Early adoption is prohibited.
In June 2009, the FASB issued SFAS No.167, “Amendments to FASB Interpretation No.46(R)”, which is now
included in ASC 810. The statement provides a new guidance how an enterprise determines whether theenterprise’s variable interests give it a controlling financial interest in VIEs. The determination is based on,among other things, VIE’s purpose and design, an enterprise’s ability to direct the activities of the VIE that mostsignificantly impact the entity’s economic performance, and if an enterprise has the obligation to absorb losses ofor the right to receive benefits from the VIE that could be significant. The statement is effective as of the
beginning of the first fiscal year that begins after November 15, 2009. Early adoption is prohibited. In February
2010, the FASB issued ASU No.2010-10, “Consolidation (Topic 810)—Amendments for Certain Investment
Funds” (“ASU No.2010-10”). The ASU provides that the consolidation requirements of SFAS No.167 aredeferred for an entity that has all the attributes of an investment company (or similar entity). On April 1, 2010,
The MHFG Group adopted SFAS No.167, together with SFAS No.166, which primarily resulted in the
consolidation of certain former qualifying SPEs, guaranteed principal money trust products and collateral loan
F-24

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
obligations (“CLO”) where the MHFG Group acts as an asset manager. The impact of adoption of SFAS No.166
and SFAS No.167 was a net increase in assets of approximately ¥460 billion, with no material impact on equity
as of April 1, 2010.
In January 2010, the FASB issued ASU No.2010-06, “Fair Value Measurements and Disclosures (Topic 820)—
Improving Disclosures about Fair Value Measurements” (“ASU No.2010-06”). The ASU provides amendments
to ASC 820-10 that require new disclosures regarding (1) transfers in and out of Levels 1 and 2 and (2) moredetailed activity in Level 3. The ASU also provides amendments to ASC 820-10 that clarify existing disclosures
regarding (1) level of disaggregation and (2) inputs and valuation techniques. The ASU is effective for interim
and annual reporting periods beginning after December 15, 2009, except for the new disclosures related to theactivity in Level 3, which do not become effective until fiscal years beginning after December 15, 2010, and forinterim periods within those fiscal years. ASU No.2010-06 is an accounting principle which expands disclosure
requirements, and has no impact on the MHFG Group’s consolidated results of operations or financial condition.
In March 2010, the FASB issued ASU No.2010-11, “Derivatives and Hedging (Topic 815)—Scope Exception
Related to Embedded Credit Derivatives” (“ASU No.2010-11”). The ASU clarifies the scope exception forembedded credit derivative features related to the transfer of credit risk, which are subject to potential
bifurcation, and indicate circumstances which do not qualify for the scope exception. The ASU is effective at the
beginning of the first fiscal quarter beginning after June 15, 2010. Early adoption is permitted. The MHFG Group
is currently evaluating the potential impact that the adoption of ASU No.2010-11 will have on its consolidated
results of operations and financial condition.
In July 2010, the FASB issued ASU No.2010-20, “Receivables (Topic 310)—Disclosures about the Credit
Quality of Financing Receivables and the Allowance for Credit Losses” (“ASU No.2010-20”). The ASU requires
disclosures that facilitate financial statement users’ evaluation of (1) the nature of credit risk inherent in theentity’s portfolio of financing receivables, (2) how that risk is analyzed and assessed in arriving at the allowancefor credit losses, and (3) the changes and reasons for those changes in the allowance for credit losses. The new
disclosures required include (1) aging of past due receivables, (2) credit quality indicators, and (3) modificationsof financing receivables. It is also required that the certain existing disclosures should be provided on adisaggregated basis. The disclosures as of the end of a reporting period are effective for interim and annual
reporting periods ending on or after December 15, 2010, whereas the disclosures about activity that occurs during
a reporting period are effective for interim and annual reporting periods beginning on or after December 15,
2010. ASU No.2010-20 is an accounting principle which expands disclosure requirements, and has no impact on
the MHFG Group’s consolidated results of operations or financial condition.
3. Business Combination
Shinko was a broker and dealer in securities and an equity method affiliate of the MHFG Group in which theGroup owned 27.32 percent of the voting equity interests immediately before the business combination. On
May 7, 2009, MHFG exchanged 30.30 percent of the voting equity interests in MHSC for 32.19 percent of thevoting equity interests in Shinko and merged the two entities, in order to strengthen the Group’s securities arm so
it is more competitive in a market with high uncertainty, improve its service providing capabilities and enable it
to offer financial services to clients on a global basis.
This transaction was accounted for as a bargain purchase because the opening market price of Shinko’s commonshares on the acquisition date was less than the fair value of net assets per common share. As a result, a pretax
gain of ¥106,310 million is recorded in Other noninterest income during the fiscal year ended March 31, 2010.

The MHFG Group recognized a gain of ¥364 million as a result of remeasuring to fair value its 27.32 percent of
the voting equity interests in Shinko held before the business combination. The gain is included in Other

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
The MHFG Group performs periodic reviews to identify impaired securities. Impairment is evaluatedconsidering the length of time and extent to which the fair value has been below cost, the financial condition andnear-term prospects of the issuer, as well as the MHFG Group’s ability and intent to hold the investments for anadequate period of time until an anticipated market price recovery or maturity.
Effective April 1, 2009, the MHFG Group adopted ASC 320, which amends the other-than-temporary
impairment model for debt securities. Under the new model, if an entity has the intent to sell a debt security or
more likely than not will be required to sell a debt security before recovery of its amortized cost basis, the fullamount of an other-than-temporary impairment loss shall be recognized immediately through earnings. Other
than either case described above, an entity must evaluate expected cash flows to be received and determine if acredit loss exists, and if so, the amount of other-than-temporary impairment related to the credit loss shall berecognized in earnings, while the remaining decline in fair value shall be recognized in other comprehensive
income, net of applicable taxes. As ASC 320 does not affect the other-than-temporary impairment model for
equity securities, equity securities deemed other-than-temporarily impaired are written down to fair value, withthe full decline recognized in earnings.
For certain Japanese government bonds held at April 1, 2009 for which an other-than-temporary impairment waspreviously recognized, the MHFG Group recorded the cumulative effect of initially applying ASC 320 as adecrease to the beginning balance of Accumulated deficit with a corresponding adjustment to Accumulated othercomprehensive income (loss), net of tax. Considering the factors that the MHFG Group does not intend to sell
those securities, it is not more likely than not that the Group will be required to sell them before recovery of theiramortized cost basis, and no credit deterioration exists in those securities, ¥99,910 million of other-thantemporary impairment charges previously recorded through earnings are reclassified to Accumulated othercomprehensive income (loss), net of tax (pre-tax amount of ¥141,212 million offset by tax effect of¥33,775 million and noncontrolling interests of ¥7,527 million).
The MHFG Group has determined that the unrealized losses on investments in a continuous loss position for 12months or more at March 31, 2010, are not other-than-temporary, because such losses have resulted primarily
from reduced liquidity, not due to credit deterioration, the Group has no intent to sell nor is it more likely than
not the Group will be required to sell those securities before recovery of their amortized costs, and the present
value of cash flows expected to be collected is not less than the amortized cost basis of the security.
For the fiscal years ended March 31, 2008, 2009 and 2010, losses resulting from write-downs for other-thantemporary impairment on available-for-sale securities were ¥661,088 million, ¥462,909 million and¥92,497 million, respectively. No impairment losses were recorded on held-to-maturity securities for those fiscal
years. For the fiscal year ended March 31, 2010, all the other-than-temporary impairment losses were recorded
through earnings, not other comprehensive income.
For the fiscal years ended March 31, 2008, 2009 and 2010, proceeds from sales of available-for-sale securities
were ¥67,553 billion, ¥47,039 billion and ¥39,430 billion, respectively. Gross realized gains on those sales were¥597,361 million, ¥212,500 million and ¥248,254 million, respectively, and gross realized losses on those sales
were ¥142,455 million, ¥120,324 million and ¥26,492 million, respectively, for the fiscal years ended March 31,
2008, 2009 and 2010.

Equity method investments
Investments in investees over which the MHFG Group has the ability to exert significant influence are accounted
for using the equity method of accounting. Such investments included marketable equity securities carried at¥49,694 million and ¥5,057 million, at March 31, 2009 and 2010, respectively. The aggregated market values of
those marketable equity securities were ¥50,132 million and ¥7,695 million, respectively.
Investments held by consolidated investment companies
The MHFG Group consolidates certain investment companies for which it has control either through ownershipor other means. Investment companies are subject to specialized industry accounting which requires investments
to be carried at fair value, with changes in fair value recorded in earnings. The MHFG Group maintains thisspecialized industry accounting for investments held by consolidated investment companies, which consist of
marketable and non-marketable investments.
Other equity interests
Other equity interests consist primarily of non-marketable equity securities outside the scope of ASC 320, forwhich the MHFG Group has neither significant influence nor control over the investees. These securities arestated at acquisition cost, with other-than-temporary impairment, if any, included in earnings. The fair values ofthese securities at March 31, 2009 and 2010 were not readily determinable. The MHFG Group monitors thestatus of each investee, including its credit rating, to determine whether impairment losses should be recognized.

Notes:(1) The amount was equal to the accumulated impairment losses.
(2) The gross amount of goodwill was ¥65,274 million at March 31, 2008, 2009 and 2010.
Goodwill in the Global Retail Group is entirely related to the MHIS operating segment. Due to an adverse change
in the business climate during the fiscal year ended March 31, 2008, it was determined that the carrying amountof the segment exceeded its fair value, which was calculated based on the quoted market price of MHIS’scommon stock, as of March 31, 2008, the date of the annual impairment test. Therefore, a goodwill impairment
loss of ¥24,543 million was recognized in the Global Retail Group during the fiscal year ended March 31, 2008.
Goodwill in the Global Corporate Group was acquired through MHCB’s subscriptions of the third-party
allocations by its subsidiary, MHSC, in December 2007 and January 2008 (Refer to Note 26 “Noncontrollinginterests”). Since the estimation of future cash flows of the MHSC operating segment was revised downwardreflecting the overall economic outlook of MHSC, it was determined that the carrying amount of the segment
exceeded its fair value as of March 31, 2008, the date of the annual impairment test. Therefore, a goodwill
impairment loss of ¥25,715 million was recognized in the Global Corporate Group during the fiscal year ended
March 31, 2008.

Financial Stabilization Funds
The Financial Stabilization Funds were initiated in 1996 by the Japanese government in connection with theliquidation of certain failed housing-loan companies. Several financial institutions including the BOJ wererequired by the Japanese government to invest in these Funds in an effort to stabilize the effects on the Japanese
economy. The returns from the investment of the Funds are first to be used to make up for a part of the losses
incurred as the housing-loan companies’ loans are collected and disposed of. The Funds are principally invested
in Japanese government bonds, but the investment income earned by the Funds does not accrue to the MHFG
Group, and as a result, the deposits are noninterest-bearing.
F-42

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
The MHFG Group made deposits with the Funds amounting to ¥359,017 million during the fiscal year ended
March 31, 1997. The deposits are expected to mature in 15 years from the deposit date. The deposits werediscounted to their present value at the time of the deposit and the discount is being accreted over the expectedperiod to maturity using the interest method. The carrying amount of the deposits as of March 31, 2009 and 2010was ¥306,511 million and ¥318,112 million, respectively.
Unearned income
Unearned income is primarily comprised of refundable fees received from consumer loan customers at the time
the loan was made, which is being deferred and recognized in earnings as earned.
Matured debentures
Matured debentures represent the principal balance of debentures that have reached maturity but have not yet
been repaid to customers.
16. Preferred stock
On January 4, 2009, MHFG abolished the fractional share system and adopted the unit share system concurrently
with the allotment of shares or fractions of a share without consideration. The allotment was made at the rate of
999 shares per one share and 9.99 shares per every 0.01 of a share. Therefore, as a result of the allotment, thenumber of shares has increased a thousandfold.

18. Dividends
The amount available for dividends under the Company Law is based on the amount recorded in MHFG’s
non-consolidated general books of account, maintained in accordance with accounting principles generally
accepted in Japan (“Japanese GAAP”) and adjusted by post period-end changes. Therefore, the consolidated
shareholders’ equity under U.S. GAAP has no effect on the determination of the amount available for dividends.
On March 31, 2010, MHFG’s capital stock, capital surplus, and retained earnings were ¥1,805,565 million,¥649,842 million, and ¥1,559,325 million, respectively, under Japanese GAAP.
In making a distribution of retained earnings, an entity must set aside in its legal reserve an amount equal to
one-tenth of the amount of retained earnings so distributed, until its legal reserve reaches to one-quarter of its
capital stock. MHFG’s legal reserve at March 31, 2010 was ¥654,192 million, of which ¥649,842 million was
included in capital surplus and ¥4,350 million in retained earnings.
In addition to the provision that requires an appropriation for legal reserve, the Company Law and the Banking
Law impose certain limitations on the amount available for dividends. Under the Company Law, MHFG’s
maximum amount available for dividends, at March 31, 2010, was ¥1,549,746 million, based on the amountrecorded in MHFG’s general books of account under Japanese GAAP. Under the Banking Law and related
regulations, MHFG has to meet the minimum capital adequacy requirements. Distributions of retained earnings,
which are otherwise distributable to shareholders, are restricted in order to maintain the minimum 4.0% Tier 1
capital for capital adequacy purposes. See Note 19 “Regulatory matters” for further discussion of regulatory
capital requirements.
Payment of dividends on shares of common stock is also subject to the prior payment of dividends on shares ofpreferred stock.

19. Regulatory matters
Regulatory capital requirements
MHFG, MHCB, MHBK, and MHTB are subject to regulatory capital requirements administered by the Financial
Services Agency (“FSA”) in accordance with the provisions of the Banking Law and related regulations. Failure
to meet minimum capital requirements may initiate certain mandatory actions by regulators that, if undertaken,
could have a direct material effect on the MHFG Group’s consolidated financial statements.
The capital adequacy guidelines applicable to Japanese banks and bank holding companies with international
operations supervised by the FSA closely follow the risk-adjusted approach proposed by the Bank forInternational Settlements (“BIS”) and are intended to further strengthen the soundness and stability of Japanesebanks. Effective March 31, 2007, new guidelines were implemented by the FSA to comply with the new capital
adequacy requirements set by BIS called Basel II. The framework of Basel II is based on the following threepillars: minimum capital requirements; supervisory review; and market discipline.
F-47

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Under the first pillar, the capital ratio is calculated by dividing regulatory capital by risk-weighted assets. With
respect to the calculation of risk-weighted assets, the MHFG Group adopts the advanced internal ratings-based
approach. Under such approach, balance sheet assets and off-balance sheet exposures, calculated under Japanese
GAAP, are assessed in terms of credit risk according to risk components such as probability of default (“PD”)
and loss given default (“LGD”) which are derived by the Group’s own internal credit experience. In addition tocredit risk, banks are required to measure and apply capital charges with respect to their market risks. Market risk
is defined as the risk of losses in on- and off-balance-sheet positions arising from movements in market prices.
Operational risk, which was introduced under Basel II with respect to regulatory capital requirements, is the riskof loss resulting from inadequate or failed internal processes, people and systems or from external events. The
Group adopted the advanced measurement approach instead of the standardized approach as of September 30,
2009 for the measurement of operational risk equivalent by taking account of the following four elements:
internal loss data; external loss data; scenario analysis; and business environment and internal control factors.
With regard to risk-based capital, these guidelines are consistent with the original BIS framework (Basel I) in
requiring a target minimum standard capital adequacy ratio of 8%, at least half of which must consist of core
capital, on both a consolidated and non-consolidated basis for banks with international operations, such as
MHCB and MHTB, or on a consolidated basis for bank holding companies with international operations, such as
MHFG.
Risk-based capital, calculated from financial statements prepared under Japanese GAAP, is classified into thefollowing three tiers: core capital (Tier 1 capital); supplementary capital (Tier 2 capital); and juniorsupplementary capital (Tier 3 capital). Tier 1 capital generally consists of shareholders’ equity less any recorded
goodwill and consolidation adjustment accounts. Tier 2 capital generally consists of: general loan-loss reserves;
45% of each of the unrealized gains on valuation of certain securities classified as “other securities” underJapanese GAAP which is similar to available-for-sale securities under U.S. GAAP, and the unrealized
appreciation in the value of land; the balance of subordinated perpetual debt; and the balance of subordinatedterm debt with an original maturity of over five years and preferred term shares up to 50% of Tier 1 capital. Tier
2 capital may be included in a bank’s risk-based capital up to the amount equivalent to Tier 1 capital, less Tier 3
capital if market risk is taken into account in the capital adequacy ratio calculation. Tier 3 capital consists of thebalance of subordinated term debt with original maturity of at least two years. Tier 3 capital may be included in
total risk-based capital subject to certain conditions, depending on the measure for market risk and the amount ofTier 1 capital.
Japanese banks are also required to comply with the supervisory review process (second pillar) and disclosure
requirements for market discipline (third pillar). Under the second pillar, banks are required to maintain adequate
capital to support all of the major risks in their business and are encouraged to develop and use better risk
management techniques in monitoring and managing such risks. Under the third pillar, banks are required toenhance disclosure, including disclosure of details of the capital adequacy ratio, the amount of each type of risk
and the method of calculation used, so that the market may make more effective evaluations.
Japanese banks with only domestic operations, such as MHBK, are subject to Japanese capital adequacy
requirements that are similar to those discussed above, except that domestic banks are required to maintain aminimum capital adequacy ratio of 4%, at least half of which must consist of Tier 1 capital, on both aconsolidated and non-consolidated basis.
If the capital adequacy ratio of a financial institution falls below the required level, the FSA may, depending
upon the extent of capital deterioration, take certain corrective action including requiring the financial institution
to submit an improvement plan to strengthen its capital base, reduce its total assets, restrict its business
operations, or other actions that could have a material effect on the MHFG Group’s financial statements.

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
MHFG’s securities subsidiaries in Japan are also subject to the capital adequacy rules of the FSA under the
Financial Instrument and Exchange Law. This rule requires securities firms to maintain a minimum capital
adequacy ratio of 120% calculated as a percentage of capital accounts less certain assets, as determined inaccordance with Japanese GAAP, against amounts equivalent to market, counterparty, and basic risks. Specificguidelines are issued as a ministerial ordinance which details the definition of essential components of the capitalratios, including capital, disallowed assets and risks, and related measures. Failure to maintain a minimum capitalratio will trigger mandatory regulatory actions. A capital ratio of less than 140% will call for regulatory reporting
and a capital ratio of 100% or less may lead to a temporary suspension of all or part of the business operations
and cancellation of the license to act as a securities broker and dealer.
Management believes, as of March 31, 2010, that MHFG, MHCB, MHBK, MHTB, and their securities
subsidiaries in Japan are in compliance with all capital adequacy requirements to which they are subject.
20. Earnings per common share
Basic earnings per common share are computed by dividing net income by the weighted average number ofcommon shares outstanding during the fiscal year. Diluted earnings per common share reflect the assumed
conversion to common shares of all convertible securities such as convertible preferred stock.
On January 4, 2009, MHFG abolished the fractional share system and adopted the unit share system concurrently
with the allotment of shares or fractions of a share without consideration. The allotment was made at the rate of
999 shares per one share and 9.99 shares per every 0.01 of a share. Therefore, as a result of the allotment, thenumber of shares has increased a thousandfold. The computations of basic and diluted earnings per commonshare are adjusted retroactively.
The following table sets forth the computation of basic and diluted earnings per common share for the fiscal
years ended March 31, 2008, 2009 and 2010:2008

Deferred tax assets and deferred tax liabilities within the same tax jurisdiction have been netted for presentationin the consolidated balance sheets.
In assessing the realizability of deferred tax assets, management considered whether it was more likely than notthat some portion or all of the deferred tax assets would not be realized. The ultimate realization of deferred tax
assets is dependent upon the generation of future taxable income during the periods in which those temporary
differences become deductible. Management considered the scheduled reversal of deferred tax liabilities,
projected future taxable income, and tax planning strategies available in making this assessment. Based upon thelevel of historical taxable income and projections for future taxable income over the periods in which thedeferred tax assets were deductible, management believed it was more likely than not that the MHFG Groupwould realize the benefits of these deductible differences, net of the existing valuation allowances at March 31,
2009 and 2010.
At March 31, 2010, the MHFG Group had net operating loss carryforwards totaling ¥5,002 billion. These net
operating losses are scheduled to expire as follows:

Included in net operating loss carryforwards in the above table are carryforwards of the holding company and a
subsidiary of ¥3,515 billion resulting mainly from intercompany capital transactions. The tax effect of thesecarryforwards is offset by a full valuation allowance.
The total amount of unrecognized tax benefits including ¥1,943 million and ¥602 million interest and penalties
was ¥11,639 million and ¥4,193 million at March 31, 2009 and 2010, respectively, of which ¥11,639 million and¥2,596 million would, if recognized, affect the Group’s effective tax rate, respectively. The Group classifies

The MHFG Group is currently subject to ongoing tax audits in some jurisdictions. The oldest years open to tax
audits in Japan, the United States and the United Kingdom are 2002, 1999 and 2002, respectively. The MHFG
Group does not anticipate that increases or decreases of unrecognized tax benefits within the next twelve months
would have a material effect on its consolidated results of operations or financial condition.
22. Pension and other employee benefit plans
Severance indemnities and pension plans
MHFG and certain subsidiaries, including MHBK, MHCB, and MHTB, sponsor and offer their employees otherthan directors and corporate auditors, contributory and non-contributory defined benefit plans. Under these plans,
employees are provided with lump-sum cash payments upon leaving the company. The amount of benefits under
the plans is principally determined based on the position, the length of service and the reason for retirement.
When employees meet certain conditions including the length of service, they may opt to receive annuity
payments instead of lump-sum payments at retirement. MHFG and certain subsidiaries also offer special
termination benefits to former employees whose contributions during their career were deemed meritorious andto those with particular circumstances.
Some of MHFG’s subsidiaries offer closed Tax-Qualified Pension Plans (closed “TQPPs”). These plans are
non-contributory defined benefit plans which provide retired employees other than directors and corporate
auditors with retirement benefits that are determined based on certain factors that include the length of service.
Under the TQPPs, employers enter into contracts with financial institutions such as trust banks or life insurersthat administer employer contributions and benefit payments.
Certain foreign offices and subsidiaries have defined contribution plans and/or defined benefit plans, of which
disclosures are combined with those for domestic benefit plans, as they are not significant.
MHFG and certain subsidiaries have several defined contribution plans. The costs recognized for contributions to
the plans for the fiscal years ended March 31, 2008, 2009 and 2010 were ¥1,785 million, ¥1,987 million and¥3,391 million, respectively.
Pension plans are not fully integrated among subsidiaries of MHFG and plan assets are managed separately byeach plan.
Net periodic benefit cost and funded status

In estimating the discount rate, the MHFG Group used interest rates on high-quality fixed-income governmental
and corporate bonds that received a rating of AA(Aa) or higher from rating agencies. The durations of suchbonds closely match that of the benefit obligation. Assumed discount rates were reevaluated at each measurement
date. The expected rate of return for each asset category is based primarily on various aspects of long-term
prospects for the economy that include historical performance and the market environment.

Investment policies and asset allocation
In managing plan assets, the MHFG Group determines the appropriate levels of risk that the Group can assume
under the given circumstances to maximize the investment returns from a long-term perspective while ensuringthat the sufficient funds will be available to plan participants and beneficiaries. Generally, the investment returns
are relative to the risks involved. In considering the maximum levels of risk that the MHFG Group can assume, it
primarily considers the following factors; the employers’ burden of maintaining the benefit plans based on thedesign of the plans and future plan contributions, the age distribution of the plan participants and beneficiaries,
the financial conditions of the employers, and the employers’ ability to absorb future variability in plan
premiums. The long-term asset allocation is based on optimal portfolios, which are estimated by expected returnand risk according to each asset category such as Japanese equity securities, Japanese debt securities, foreign
equity securities and foreign debt securities. Additionally, the asset allocation is reviewed whenever there arelarge fluctuations in pension plan liabilities caused by modifications of pension plans, or there are changes in themarket environment. When selecting an investment in each asset category, the MHFG Group takes into
consideration credit standing of an investee, concentration of credit risk to a certain investee, liquidity of anfinancial instrument, etc. The investments in each asset category are further diversified across funds, strategies,
sectors, etc. There is no significant investment in a single investee except Japanese government bonds.
Certain subsidiaries of MHFG established employee retirement benefit trusts and transferred their assets to thetrusts as plan assets. These assets are separated from employer’s proprietary assets for the payment to the plan
beneficiaries. The assets held in these trusts are primarily Japanese equity securities and have been entrusted
directly with qualified trustees including trust banks.
The plan assets designated to the TQPPs have been invested in assets with low investment risk because the plans
have already been closed to new participants.

23. Stock-based compensation
Concurrently with the abolishment of, and as an alternative to the retirement allowances program for directors
and executive officers of MHFG, MHBK, MHCB, and MHTB, the MHFG Group introduced stockcompensation-type stock options, in the form of stock acquisition rights, for directors (excluding the outside
directors) and executive officers of the respective companies (hereinafter referred to collectively as the“Directors”) in June 2008. The Group also introduced similar stock compensation-type stock options for
MHSC’s Directors in June 2009.
The Group maintains following three types of stock-based compensation plan.
In each plan, 1,000 shares of common stock of the designated company (i.e. MHFG common stock for Directorsof MHFG, MHBK and MHCB, MHTB common stock for Directors of MHTB, and MHSC common stock for
Directors of MHSC) shall be issued or transferred upon exercise of each of the stock acquisition rights. The
amount to be paid upon exercise shall be 1 yen per share.
The contractual term of the stock acquisition rights of each plan is 20 years. A holder may exercise the stockacquisition rights only after the date on which such holder loses the status as a Director of MHFG, MHBK,MHCB, MHTB or MHSC. In case of MHSC, if a holder assumes the status as a Director of the company
immediately after losing the status as a Director of the company, the holder may exercise the stock acquisitionrights only after losing such status finally and definitely.

There are no non-vested stock options remaining as of March 31, 2010.
The following table presents the assumptions to estimate the fair value of stock acquisition rights on the date of
grant used in the Black-Scholes option pricing model. The risk-free interest rate is based on the Japanese
government bonds yield curve for the expected remaining term in effect at the date of grant. The expectedvolatility is based on the historical trading data of MHFG common stock. The expected remaining term is basedon the average service period of Directors of MHFG, MHBK, and MHCB, which represents the period of timethat stock acquisition rights granted are expected to be outstanding. The expected dividend yield is based on thedividend rate of MHFG common stock at the date of grant.

24. Derivative financial instruments
The MHFG Group uses derivative financial instruments in response to the diverse needs of customers, to control
the risk related to the assets and liabilities of the MHFG Group, as part of its asset and liability management, andfor proprietary trading purposes. The MHFG Group is exposed primarily to market risk associated with interest
rate, commodity, foreign currency, and equity products. Market risk arises from changes in market prices orindices, interest rates and foreign exchange rates that may result in an adverse change in the market value of thefinancial instrument or an increase in its funding costs. Exposure to market risk is managed by imposing position
limits and monitoring procedures and by initiating hedging transactions. In addition to market risk, the MHFG
Group is exposed to credit risk associated with counterparty default or nonperformance on transactions. Credit
risk arises from counterparty failure to perform according to the terms and conditions of the contract and thevalue of the underlying collateral held, if applicable, is not sufficient to recover resulting losses. The exposure tocredit risk is measured by the fair value of all derivatives in a gain position and its potential increase at thebalance sheet dates. The exposure to credit risk is managed by entering into legally enforceable master netting
agreements to mitigate the overall counterparty credit risk, requiring underlying collateral and guarantees basedon an individual credit analysis of each obligor and evaluating credit features of each instrument. In addition,
credit approvals, limits and monitoring procedures are also imposed.

Notes:(1) Notional amount represents the sum of gross long and gross short third-party contracts.
(2) Derivative receivables and payables are recorded in Trading account assets and Trading account liabilities,
respectively.
The MHFG Group provided and/or accepted cash collateral for derivative transactions under master netting
arrangements. Those collateral, not offset against derivative positions, was included in Other assets and Otherliabilities, respectively, of which amounts were ¥1,237 billion and ¥814 billion at March 31, 2009, and ¥853
billion and ¥498 billion at March 31, 2010, respectively.
Hedging activities
In order to qualify for hedge accounting, a derivative must be considered highly effective at reducing the risk
associated with the exposure being hedged. Each derivative must be designated as a hedge, with documentationof the risk management objective and strategy, including identification of the hedging instrument, the hedged
item and the risk exposure, and how effectiveness is to be assessed prospectively and retrospectively. The extent
to which a hedging instrument is effective at achieving offsetting changes in fair value or cash flows must be
assessed at least quarterly. Any ineffectiveness must be reported immediately in earnings. The MHFG Group’s
hedging activities include fair value and net investment hedges.
Fair value hedges
The MHFG Group primarily uses bond options to modify exposure to changes in fair value of available-for-saledebt securities. For qualifying fair value hedges, all changes in the fair value of the derivative and thecorresponding hedged item relating to the risk being hedged are recognized in earnings in Investment gains(losses)—net. The change in fair value of the portion of the hedging instruments excluded from the assessment ofhedge effectiveness is recorded in Trading account gains (losses)—net. No ineffectiveness exists because the
MHFG Group chooses to exclude changes in the option’s time value from the effectiveness test. If the hedge
relationship is terminated, the fair value adjustment to the hedged item continues to be reported as part of thebasis of the item and is amortized to earnings as a yield adjustment.

for the fiscal years ended March 31, 2008 and 2009, respectively. No ineffectiveness was recognized in earnings
for those fiscal years.
Net investment hedges
The MHFG Group uses forward foreign exchange contracts and foreign currency-denominated debt instruments
to protect the value of net investments in non-Japanese subsidiaries from foreign currency exposure. Under net
investment hedges, both derivatives and nonderivative financial instruments qualify as hedging instruments. For
net investment hedges, the changes in the fair value of a hedging derivative instrument or nonderivative hedging
financial instrument is recorded in Foreign currency translation adjustments within Accumulated othercomprehensive income (loss), provided that the hedging instrument is designated and is effective as a hedge ofthe net investment. The portion of the hedging instruments excluded from the assessment of hedge effectivenessis recorded in Foreign exchange gains (losses)—net in earnings.

Derivative instruments not designated or qualifying as hedges
The MHFG Group enters into the following derivative transactions that do not qualify for hedge accounting witha view to implementing risk management hedging strategies: (1) interest-rate swap transactions for the purpose

AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)of hedging interest-rate risks in deposits, loans etc., (2) currency swap transactions for the purpose of hedging theforeign exchange risk of these assets, and (3) credit derivatives for the purpose of hedging the credit risk in loans,residential mortgage-backed securities (“RMBS”), commercial mortgage-backed securities (“CMBS”),
collateralized loan obligations (“CLO”) and other similar assets. Such derivatives are accounted for as trading
positions. The change in fair value of those instruments except certain credit derivatives hedging the credit risk inloans are recorded in Trading account gains (losses)—net, even though they are used to mitigate or transform therisk of exposures arising from banking activities. The net loss resulting from changes in the fair values of certain
credit derivatives where the Group purchases protection to mitigate its credit risk exposure, related to its
corporate loan portfolio, is recorded in Other noninterest expenses.

Credit derivatives
A credit derivative is a bilateral contract between a seller and a buyer of protection against the credit risk of aparticular entity. Credit derivatives generally require that the seller of credit protection make payments to thebuyer upon the occurrence of predefined credit events, which include bankruptcy, dissolution or insolvency of
the referenced entity. The MHFG Group either purchases or writes protection on either a single name or aportfolio of reference credits. The Group enters into credit derivatives to help mitigate credit risk in its corporateloan portfolio and other cash positions, to take proprietary trading positions, and to facilitate client transactions.
The notional amount of credit derivatives represents the maximum potential amount of future payments the seller
could be required to make. If the predefined credit event occurs, the seller will generally have a right to collect on
the underlying reference credit and any related cash flows, while being liable for the full notional amount ofcredit protection to the buyer. The Group manages credit risk associated with written protection by purchasingprotection with identical or similar underlying reference credit, which substantially offsets its exposure. Thus, thenotional amount is not a reliable indicator of the Group’s actual loss exposure.

Note: The maximum potential amount of future payment is the notional amount of the credit derivatives where
the Group wrote the credit protection, and it has not been reduced by the Group’s right of collection overthe underlying assets and the related cash flows, nor netted against that of credit protection purchased.
Credit-related contingent features
Certain of the MHFG Group’s derivative instruments contain provisions that require the Group’s debt tomaintain an investment grade credit rating from the major credit rating agencies. If the Group’s debt were to fall
below investment grade, the counterparties to the derivative instruments could request immediate payment or
demand immediate and ongoing full overnight collateralization on derivative instruments in the Group’s net
liability positions. The aggregate fair value of all derivative instruments with such credit-risk-related contingent
features in liability positions on March 31, 2010 was ¥2,170 billion. As the Group has provided ¥1,736 billion as
collateral to the counterparties in its normal course of business, if the contingent features described above were
triggered on March 31, 2010, the amount immediately required to settle would be ¥434 billion.

25. Commitments and contingencies
Obligations under guarantees
The MHFG Group provides guarantees or indemnifications to counterparties to enhance their credit standing andenable them to complete a variety of business transactions. The guarantee represents an obligation to makepayments to third parties if the counterparty fails to fulfill its obligation under a borrowing arrangement or othercontractual obligation.
The Group records all guarantees and similar obligations subject to ASC 460, “Guarantees” (“ASC 460”) at fairvalue on the consolidated balance sheets at the inception of the guarantee. The carrying amount of guarantees andsimilar obligations at March 31, 2009 and 2010 was ¥18 billion and ¥15 billion, respectively, and was included in
Other liabilities.
The types of guarantees under ASC 460 provided by the MHFG Group are described below.
Performance guarantees
Performance guarantees are issued to guarantee customers’ performance under contractual arrangements such asa tender bid on a construction project or the completion of a construction project.
Guarantees on loans
Guarantees on loans include an obligation to guarantee the customer’s borrowing contracts. The MHFG Group isrequired to make payments to the guaranteed parties in the event that customers fail to fulfill obligations under
the contracts.
Guarantees on securities
Guarantees on securities include an obligation to guarantee securities, such as bonds issued by customers.
Other guarantees
Other guarantees include an obligation to guarantee customers’ payment, such as tax payments.
Guarantees for the repayment of trust principal
The MHFG Group provides certain trust products with guarantees for the repayment of trust principal, e.g., loan
trusts and certain jointly operated designated money trusts. Pursuant to Japanese trust-related laws, trustees areprohibited from compensating beneficiaries for any loss in the beneficial interests in each trust. However, under aspecial condition of the Japanese trust-related laws, trust banks as trustees are allowed to enter into an agreement
to compensate for any loss in the principal of the trust. The MHFG Group manages and administers the trust
assets to minimize exposures against losses from the guarantees for the repayment of trust principal, including
writing-off impaired loans and charging it to the trust account profits. In performing its fiduciary duties, theMHFG Group also manages the trust assets separately from its own proprietary assets on behalf of customers andkeeps separate records for the trust activities. The contract amounts of guarantees for repayment of trust principal
were presented in the tables below. Part of the trust account profits is set aside as a reserve in trust accounts toabsorb losses in the trust asset portfolios in accordance with relevant Japanese laws concerning the trust business
and/or trust agreements. Statutory reserves for loan trusts and reserves for jointly operated designated money
trusts are calculated based on the trust principal or the balance of loans and other assets in the trust accounts.
Since the probability of principal indemnification is judged to be remote, the MHFG Group had no related
reserve for credit losses recorded in its consolidated financial statements.
F-67

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Liabilities of trust accounts
The MHFG Group, as trustee, may enter into an agreement with a third party who is not the party to the relevant
trust agreement to the extent necessary to handle the trust affairs for the purpose of fulfilling the objectives of thetrust and, as such, the trustee shall be allowed to assume certain liabilities. Pursuant to Japanese trust-relatedlaws, the trustee is ultimately liable to pay those liabilities out of its proprietary assets in the event that the trust
assets are insufficient to cover those liabilities and the trust beneficiary is unable to compensate the shortfall. To
avoid the demand for payment out of the proprietary assets, the trustee can enter into a special covenant oflimited liability under which the trust creditors agree to limit the trustee’s liability to the value of the trust assets
and to waive the right for compulsory execution against the trustee’s proprietary assets. The amount of trust
liabilities rarely exceeds the amount of trust assets and, therefore, those liabilities are covered by thecorresponding trust assets. However, in the event that the trust assets cannot cover all the trust liabilities and thetrustee has to pay out of its proprietary assets, the trustee can require the trust beneficiary to compensate for such
trust liabilities under the Trust Law. The MHFG Group regularly monitors the condition of trust accounts tominimize exposures against making such payment.
The amounts of such liabilities in the trust accounts excluding those with the special covenant of limited liability
were presented in the tables below. Liabilities of trust accounts principally include obligations to return collateral
under security lending transactions and others.
Derivative financial instruments
Certain written options and credit default swaps are deemed guarantees pursuant to the definition of guarantees in
ASC 460 if (i) these contracts require the MHFG Group to make payments to counterparties based on changes inan underlying instrument or index, (ii) the contract cannot be cash-settled, and (iii) it is probable that thecounterparty held the underlying instrument at inception of the contract. Because it is difficult in practice todetermine whether condition (iii) exists, the MHFG Group has decided to include all credit default swaps andcertain written options, excluding written options outside the scope of ASC 460 such as written call options, inthe mandatory guarantee disclosures, irrespective of whether the counterparty has the asset or liability relating to
the underlying.
Maximum exposure under guarantee contracts
The table below summarizes the remaining term and maximum potential amount of future payments by type ofguarantee at March 31, 2009 and 2010. The maximum potential amount of future payments disclosed below
represents the contractual amounts that could be repaid in the event of guarantees execution, without
consideration of possible recoveries under recourse provisions or from collateral held. With respect to written
options included in derivative financial instruments in the table below, in theory, the MHFG Group is exposed tounlimited losses; therefore, the table shows notional amounts of the contracts as a substitute for the maximum
exposure.

F-68

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
The MHFG Group, when necessary, requires collateral such as cash, investment securities and real estate or
third-party guarantees depending on the amount of credit risk involved, and employs means such as
sub-participation to reduce the credit risk associated with guarantees. The maximum exposure or notionalamounts below does not represent the expected losses from the execution of the guarantees.

Note: Investment grade in the internal rating scale is generally corresponding to BBB– or above in externalrating scale.
Other off-balance-sheet instruments
In addition to guarantees, the MHFG Group issues other off-balance-sheet instruments to its customers, such as
lending-related commitments and commercial letters of credit. Under the terms of these arrangements, theMHFG Group is required to extend credit or make certain payments upon the customers’ request.

F-69

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Commitments to extend credit
Commitments to extend credit are legally binding agreements to lend to customers on demand. They usually
have set maturity dates. These agreements differ from guarantees in that they are generally revocable or containprovisions that enable the MHFG Group to avoid payment or reduce the amount of credit extended under certain
conditions, such as the deterioration of the borrower’s financial condition or other reasonable conditions. The
MHFG Group monitors the financial condition of the potential borrowers throughout the commitment period todetermine whether additional collateral or changes in the terms of the commitment are necessary. Since many ofthese commitments to extend credit expire without being drawn upon, the total commitment amounts do notnecessarily represent future cash requirements.
Commitments to invest in securities
Commitments to invest in securities include legally binding contracts to make additional contributions toinvestment funds, such as venture capital funds or corporate recovery funds in accordance with the terms ofinvestment agreements.
Commercial letters of credit
Commercial letters of credit are issued in connection with customers’ trade transactions. Normally, the customers
cannot receive the goods until they make payment to a bank, and therefore these commercial letters of credit arecollateralized by the underlying goods. Upon issuance of commercial letters of credit, the MHFG Group monitors
the credit risk associated with these transactions to determine if additional collateral is required.
The table below summarizes the contractual amounts with regard to these undrawn commitments at March 31,
2009 and 2010:

Total rental expense for the fiscal years ended March 31, 2008, 2009 and 2010 was ¥99,339 million,¥104,605 million and ¥106,177 million, respectively.
During prior years, the MHFG Group’s major banking subsidiaries sold their head offices (including land,buildings, facilities and equipment) to third parties. Concurrent with the sales, these subsidiaries leased theproperties back for periods of 5 and 10 years at total lease payment for the whole period of ¥214,690 million,
which then decreased to ¥211,186 million, as the terms of certain lease agreements were changed during the
fiscal year ended March 31, 2009. The MHFG Group recorded the transactions as operating leases. The future
minimum lease payments under the terms of the related lease agreements were ¥94,655 million, ¥69,947 millionand ¥54,735 million at March 31, 2008, 2009 and 2010, respectively.
Legal proceedings
The MHFG Group is involved in normal collection proceedings initiated by the Group and other legal
proceedings in the ordinary course of business.
The Group’s Indonesian subsidiary acts as collateral agent for the trustee of bond issuances made by subsidiaries
of Asia Pulp & Paper Company Ltd. (“APP”). In that role, the subsidiary is involved in disputes between thebondholders and such APP subsidiaries in their capacities as the issuers, guarantors and/or pledgors of security
for the bonds relating to foreclosure proceedings on the collateral and has been named as a defendant in lawsuitsbrought by the obligors under the bonds in Indonesia. The Group’s consolidated financial statements do notinclude a reserve in relation to these disputes because the Group does not believe that the resolution of this matter
will have a significant impact on the consolidated financial condition or results of operations of the Group,
although there can be no assurance as to the foregoing.
26. Noncontrolling interests in consolidated subsidiaries
Noncontrolling interests represent the equity for the remaining outstanding voting stock of subsidiaries not
owned by the MHFG Group. The changes in noncontrolling interests in fiscal years ended March 31, 2008, 2009,
F-71

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
and 2010 consisted of noncontrolling interests in net income or loss of subsidiaries, noncontrolling interests inchanges in other comprehensive income of subsidiaries and changes resulting from changes in the ownership
percentage of the Group in certain subsidiaries.
During the fiscal year ended March 31, 2008, MHCB subscribed to new share issuances in total of ¥400 billion
through third-party allocations by its subsidiary, MHSC. The purpose of the increases in capital by MHSC was tostrengthen the capital base and business platform for the entire MHSC group. As a result of these transactions,
the Group’s ownership in MHSC was increased to 89.81% at March 31, 2008.
During the fiscal year ended March 31, 2010, MHFG exchanged certain voting equity interests in MHSC for
those in Shinko, which had been an equity method affiliate of the Group, and merged the two entities. As a resultof the transaction, the Group’s ownership in MHSC was decreased to 59.22% at March 31, 2010. See Note 3“Business Combination” for further details of the merger.
27. Variable interest entities and securitizations
Variable interest entities
In the normal course of business, the MHFG Group is involved with VIEs primarily through the following typesof transactions: asset-backed commercial paper/loan programs, asset-backed securitizations, investment funds,
trust arrangements, and structured finance. The Group consolidated certain of these VIEs, where the Group wasdeemed to be the primary beneficiary through participation in a majority of expected losses, expected residual
returns or both. There are also other VIEs, where the Group determined that it was not the primary beneficiary
but had significant variable interests. In evaluating the significance of the variable interests, the Group
comprehensively takes into consideration the extent of its involvement with each VIE, such as the seniority of its
investments, the share of its holding in each tranche and the variability it expects to absorb, as well as otherrelevant facts and circumstances. The likelihood of loss is not necessarily relevant to the determination ofsignificance, and therefore, “significant” does not imply that there is high likelihood of loss. The maximum
exposure to loss that is discussed in this section is the contractual or notional amounts of liquidity facilities andother off-balance-sheet credit related support or principal amount of financing or investments, and it is notindicative of the ongoing exposure which is managed within the Group’s risk management framework.
The tables below show consolidated assets of the Group’s consolidated VIEs as well as total assets and maximum
exposure to loss for its significant or sponsored unconsolidated VIEs, as of March 31, 2009 and 2010:

Asset-backed commercial paper/loan programs
The MHFG Group manages several asset-backed commercial paper/loan programs that provide its clients’
off-balance-sheet and/or cost-effective financing. The VIEs used in the programs purchase financial assets,
primarily receivables, from clients participating in the programs and provide liquidity through the issuance ofcommercial paper or borrowings from the MHFG Group backed by the financial assets. While customers
normally continue to service the transferred receivables, the MHFG Group underwrites, distributes, and makes amarket in commercial paper issued by the conduits. The MHFG Group typically provides program-wide liquidity
and credit support facilities and, in some instances, financing to the VIEs. The MHFG Group determined that it
absorbs a majority of expected losses or expected residual returns through the facilities and, therefore,
consolidated this type of VIEs.
Asset-backed securitizations
The MHFG Group acts as an arranger of various types of structured finance to meet clients’ various off-balancesheet financing needs. In substantially all of these structured financing transactions, the transfer of the financial
asset by the client is structured to be bankruptcy remote by use of a bankruptcy remote entity, which is deemed to
be a VIE because its equity holder does not have decision making rights. The MHFG Group receives fees forstructuring and/or distributing the securities sold to investors. In some cases, the MHFG Group itself purchases
the securities issued by the entities and/or provides loans to the VIEs.
In addition, the MHFG Group establishes several single-issue and multi-issue special purpose entities that issue
collateralized debt obligations (“CDO”) or CLO, synthetic CDO/CLO or other repackaged instruments to meetclients’ and investors’ financial needs. The MHFG Group also arranges securitization transactions including
CMBS, RMBS and others. In these transactions, the MHFG Group acts as an underwriter, placement agent, asset
manager, derivatives counterparty, and/or investor to debt and equity instruments.
In certain VIEs, where the MHFG Group provides liquidity and credit support facilities, writes credit protection
or invests in debt or equity instruments, the Group determined that it absorbs a majority of expected losses or
expected residual returns and, therefore, consolidated such VIEs.
F-74

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Investments in securitization products
The MHFG Group invests in, among other things, various types of CDO/CLO, synthetic CDO/CLO andrepackaged instruments, CMBS and RMBS arranged by third parties for the purpose of generating current
income or capital appreciation, which all utilize entities that are deemed to be VIEs. By design, such investments
were investment grade at issuance and held by a diverse group of investors. The Group usually takes into
consideration the seniority and the share of its investments by each tranche to evaluate whether it is the primary
beneficiary. The loss amount of securities and loans is generally limited to the amount invested because theGroup has no contractual involvement in such VIEs beyond its investments. However, the Group consolidated
some VIEs, mostly where the transactions were tailored by the third party arrangers to meet the Group’s needs asa sole investor.
Investment funds
The MHFG Group invests in various investment funds including securities investment trusts, which collectively
invest in equity and debt securities that include listed Japanese securities and investment grade bonds. Investment
advisory companies or fund management companies, including the Group’s subsidiaries and affiliates, administerand make investment decisions over such investment funds. The Group consolidates certain investment funds
where it is deemed to be the primary beneficiary.
Trust arrangements
The MHFG Group offers a variety of asset management and administration services under trust arrangements
including security investment trusts, pension trusts and trusts used in the securitization of assets originated byand transferred to third parties. The Group receives trust fees for providing services as an agent or fiduciary on
behalf of beneficiaries.
With respect to guaranteed principal money trust products, the MHFG Group assumes certain risks by providing
guarantees for the repayment of principal as required by the trust agreements or relevant Japanese legislation.
The MHFG Group manages entrusted funds primarily through the origination of high quality loans and othercredit-related products, investing in investment grade marketable securities such as Japanese government bonds
and placing cash with the MHFG Group’s subsidiary trust banks (Refer to Note 13 “Due to trust accounts”). The
MHFG Group determined that it does not absorb a majority of expected losses or expected residual returns inconnection with these trust arrangements but had significant variable interests and, therefore, the trust accounts
are not included in the consolidated financial statements of the MHFG Group but are disclosed in the tables
above as significant or sponsored unconsolidated VIEs. See Note 25 “Commitments and contingencies” for thebalances of guaranteed trust principal at March 31, 2009 and 2010.
With respect to non-guaranteed trust arrangements, the MHFG Group manages and administers assets on behalfof its customers (trust beneficiaries) in the capacity of a trustee and fiduciary, and does not assume risks
associated with the entrusted assets. For substantially all non-guaranteed trust arrangements, the trust
beneficiaries receive the majority of expected residual returns and absorb the majority of expected losses basedon the performance of the trust assets and, therefore, such trust accounts are not included in the consolidated
financial statements of the MHFG Group.
Special purpose entities created for structured finance
The MHFG Group is involved in real estate, commercial aircraft and other vessel and machinery and equipment
financing to VIEs. However, the Group determined that it does not absorb a majority of the expected losses or
F-75

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
expected residual returns in these entities based on an internally developed model. Furthermore, taking into
consideration that the Group typically only provides senior financing with credit enhanced by subordinatedinterests and, if necessary, may act as an interest rate swap counterparty, the Group’s variable interests in these
entities are considered not to be significant.
Securitization
The MHFG Group had no significant transfers of financial assets, recognized no significant gains or losses andretained no significant interests in securitization transactions accounted for as sales during the periods sinceApril 1, 2005. The MHFG Group had securitized mortgage loans during a previous fiscal year. In connection
with such securitization transaction, the Group provides servicing for and holds retained interests in the
securitized mortgage loans. The Group’s retained interests consist of subordinated beneficial interests andretained credit exposure. The values of the subordinated beneficial interests are subject to credit risk, interest raterisk and prepayment risk on the securitized financial assets. The retained credit exposure is in the form of aguarantee by a subsidiary of the Group. The carrying amount of this retained credit exposure was not consideredmaterial at March 31, 2009 and 2010. No servicing assets or liabilities were recorded as a result of thistransaction since the Group received adequate compensation.
The following information is related to a mortgage loan securitization transaction executed during the fiscal year
ended March 31, 2005. Because the entity utilized is structured as a qualifying SPE as defined in ASC 860, it isexempt from consolidation and the transfer is accounted for as a sale.
Key economic assumptions used in measuring the fair value of the subordinated beneficial interests at the date of
securitization were as follows:

These sensitivities are hypothetical and should be used with caution. As the figures indicate, changes in fair value
based on a 10 percent variation in assumptions generally cannot be extrapolated because the relationship of thechange in assumption to the change in fair value may not be linear. Also, in this table, the effect of a variation ina particular assumption on the fair value of the subordinated beneficial interests is calculated without changing
any other assumption; in reality, changes could be correlated and changes in one factor may result in changes inanother (for example, increases in market interest rates may result in lower prepayments and increased credit
losses), which might magnify or counteract the sensitivities.

29. Fair value
Fair value measurements
ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability(an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction
between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which
requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs whenmeasuring fair value. Additionally, ASC 820 precludes (1) deferral of gains and losses at inception of certain
derivative contracts whose fair value was not evidenced by market-observable data, and (2) use of block
discounts when measuring the fair value of instruments traded in an active market, which were previously
applied to large holdings of publicly traded financial instruments.
Fair value hierarchy
ASC 820 specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques
are observable or unobservable. The standard describes three levels of inputs that may be used to measure fairvalue:
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 andliabilities include debt securities with quoted prices that are traded less frequently than exchangetraded instruments. If no quoted market price is available, the fair values of debt securities and overthe-counter derivative contracts in this category are determined using a pricing model with inputs thatare observable in the market or can be derived principally from or corroborated by observable market
data.
F-78

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Level 3

Unobservable inputs that are supported by little or no market activity and that are significant to the fairvalue of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value
is determined using pricing models, discounted cash flow methodologies, or similar techniques, as wellas instruments for which the determination of fair value requires significant management judgment or
estimation.

Following is a description of valuation methodologies used for assets and liabilities measured at fair value on arecurring basis, including the general classification of such instruments pursuant to the fair value hierarchy and
the Group’s valuation techniques used to measure fair values. During the fiscal year ended March 31, 2010, there
were no material changes made to the Group’s valuation techniques and related inputs.
Trading securities and trading securities sold, not yet purchased
When quoted prices for identical securities are available in an active market, the Group uses the quoted prices tomeasure fair values of securities and such securities are classified in Level 1 of the fair value hierarchy. Level 1
securities include highly liquid government bonds and Ginnie Mae securities. When quoted prices for identicalsecurities are available, but not actively traded, such securities are classified in Level 2 of the fair value
hierarchy. When no quoted market price is available, the Group estimates fair values by using a pricing modelwith inputs that are observable in the market and such securities are classified in Level 2 of the fair value
hierarchy. Level 2 securities include Japanese local government bonds, corporate bonds, and commercial paper.
When less liquidity exists for securities, the quoted prices are stale or the prices from independent sources vary,such securities are generally classified in Level 3 of the fair value hierarchy. Level 3 securities include
securitization products such as RMBS, CDO, asset-backed securities (“ABS”), and CLO.
The investment funds are classified in either Level 1, Level 2, or Level 3 of the fair value hierarchy. Among
those funds, exchange-traded funds (“ETF”) are classified in Level 1, while the others are classified in Level 2 orLevel 3. Investment trust and hedge funds are generally classified in Level 2, since those funds are measured at
NAV per share and the MHFG Group has the ability to redeem its investment with the investees at NAV pershare at the measurement date or within the near term. Private equity funds and real estate funds measured at
NAV per share are generally classified in Level 3, since the Group never has the ability to redeem its investment
with the investees at NAV per share, nor can it redeem its investment with the investees at NAV per share at themeasurement date or within the near term.
Derivative financial instruments
Exchange-traded derivatives are valued using quoted market prices and so are classified in Level 1 of the fairvalue hierarchy. However, the majority of derivatives entered into by the Group are executed over-the-counterand so are valued using internal valuation techniques as no quoted market price is available for such instruments.
The valuation techniques depend on the type of derivatives. The principal techniques used to value these
instruments are discounted cash flow models and the Black-Scholes option pricing model, which are widely
accepted in the financial services industry. The key inputs vary with the type of derivatives and the nature of theunderlying instruments and include interest rate yield curves, foreign exchange rates, the spot price of theunderlying, volatility and correlation. Each item is placed in either Level 2 or Level 3 depending on theobservability of the significant inputs to the model. Level 2 derivatives include plain vanilla interest rate andcurrency swaps and option contracts. Derivative contracts valued using significant unobservable correlation orvolatility are classified in Level 3 of the fair value hierarchy.

Investments
Fair values of available-for-sale securities are determined primarily using the same procedures described for
trading securities. Level 1 securities include highly liquid government bonds and listed stocks. Though Level 3
securities include most securitization products such as RMBS, CMBS, CDO, ABS, and CLO, certain
securitization products such as Japanese RMBS are classified in Level 2, if their fair values are quoted prices inmarkets that are not active, or determined using a pricing model that can be corroborated by observable market
data.
Other investments, except investments held by consolidated investment companies, have not been measured atfair value on a recurring basis. Investments held by consolidated investment companies consist of marketable andnon-marketable equity securities. The fair value of the marketable equity securities is based upon quoted market
prices. The fair value of the non-marketable equity securities is based upon significant management judgment, asvery limited quoted prices exist. When evaluating such securities, the Group firstly considers recent market
transactions of the identical security, if applicable. Otherwise, the Group uses commonly accepted valuation
techniques such as earnings multiples based on comparable public securities. Non-marketable equity securities
are generally classified in Level 3 of the fair value hierarchy.
Long-term debt
Where fair value accounting has been elected for structured notes, the fair values of those are determined byincorporating the fair values of embedded derivatives primarily derived from the same procedures described forderivative financial instruments. Such instruments are classified in Level 2 or Level 3 depending on theobservability of significant inputs to the model of the embedded derivatives. Where fair value accounting has
been elected for non-structured notes issued by consolidated VIEs, the fair values of those are determinedprimarily based upon the fair values of the underlying assets held by consolidated VIEs. Such instruments areclassified in Level 3 because the underlying assets held by consolidated VIEs are securitization products
classified in Level 3.

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Loans held-for-sale in the table above are accounted for at the lower of cost or fair value at the end of the fiscal
year. The items of which fair values are determined by using actual or contractually determined selling price data
are classified as Level 2. Due to the lack of current observable market information, the determination of fairvalue for items other than above requires significant adjustment based on management judgment and estimation,
which leads such items into Level 3.
Other investments in the table above have been impaired and written down to fair value. Other investments
consist of non-marketable equity securities outside the scope of ASC 320, which have no readily available quoted
price. The fair value of these impaired non-marketable equity securities is determined primarily by using aliquidation value technique. As significant management judgment or estimation is required, these items areclassified as Level 3.
Other liabilities in the table above represent amounts recorded for loan commitments where loans drawn under
the commitment will be held for sale. The losses were measured in the same manner as loans held-for-sale above.
Fair value option
The MHFG Group elected the fair value option for certain eligible financial instruments described below.
Foreign currency denominated available-for-sale securities
Prior to the adoption of ASC 825, the changes in fair value of available-for-sale securities had been accounted forin Accumulated other comprehensive income (loss), net of tax, while the changes in fair value caused by foreignexchange fluctuation of foreign currency denominated financial liabilities had been accounted for in earnings.
The MHFG Group elected the fair value option for those securities to mitigate the volatility in earnings due to thedifference in the recognition of foreign exchange risk between available-for-sale securities and financial
liabilities. Following the election of the fair value option, these securities have been reported as trading securities
in Trading account assets.
Certain hybrid financial instruments
The MHFG Group issues structured notes as part of its client-driven activities. Structured notes are debt
instruments that contain embedded derivatives. The Group elected the fair value option for certain structured
notes to mitigate accounting mismatches and to achieve operational simplifications. Following the election of thefair value option, those structured notes continue to be reported in Long-term debt and interest on thosestructured notes continues to be reported in Interest expense on long-term debt. The differences between theaggregate fair value of those structured notes for which the fair value option has been elected and the aggregate
unpaid principal balance of such instruments were ¥31 billion and ¥40 billion at March 31, 2009 and 2010,
respectively. The net unrealized gains resulting from changes in fair values of those structured notes of ¥3 billionand ¥9 billion were recorded in Other noninterest income for the fiscal years ended March 31, 2009 and 2010,
respectively.
Financial assets and liabilities held by consolidated VIEs
The MHFG Group consolidates certain VIEs that issue CDOs where MHFG or its subsidiaries have been
determined to be the primary beneficiary. The Group elected the fair value option for certain assets held andnotes issued by those VIEs to eliminate the divergence between accounting income and economic income. The
assets were reported in Trading account assets, while the notes were reported in Long-term debt. The fair value
F-84

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
option enabled the Group to recognize the gains or losses attributing to only the notes that the Group held. The
differences between the aggregate fair value of those notes for which the fair value option has been elected andthe aggregate unpaid principal balance of such instruments were ¥60 billion and ¥57 billion at March 31, 2009
and 2010, respectively. The net unrealized gains resulting from changes in fair values of those notes of ¥2 billion
were recorded in Trading account gains (losses)—net, for the fiscal year ended March 31, 2009. There was no
significant change in fair values of those notes during the fiscal year ended March 31, 2010.
Fair value of financial instruments
ASC 825 requires the disclosure of the estimated fair value of financial instruments. Fair value of financial
instruments is the amount that would be exchanged between willing parties, other than in a forced sale or
liquidation. Quoted market prices, if available, are best utilized as estimates of the fair values of financial
instruments. However, since no quoted market prices are available for certain financial instruments, fair values
for such financial instruments have been estimated based on management’s assumptions, discounted cash flow
models or other valuation techniques. Such estimation methods are described in more detail below. Theseestimates could be significantly affected by different sets of assumptions. There are certain limitations tomanagement’s best judgment in estimating fair values of financial instruments and inherent subjectivity involvedin estimation methodologies and assumptions used to estimate fair value. Accordingly, the net realizable or
liquidation values could be materially different from the estimates presented below.
ASC 825 does not require the disclosure of the fair value of nonfinancial instruments.
The carrying amounts and fair values of certain financial instruments, excluding the financial instruments outside
the scope of ASC 825 such as the equity method investments and lease contracts as defined in ASC 840,

MIZUHO FINANCIAL GROUP, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Following is a description of valuation methodologies used for estimating fair value for financial assets andliabilities not carried at fair value on the Group’s consolidated balance sheets.
Cash and due from banks, call loans and funds sold, and receivables under resale agreements and securities
borrowing transactions
The carrying value of short-term financial assets, such as cash and due from banks, interest-bearing deposits inother banks, call loans and funds sold, and receivables under resale agreements and securities borrowing
transactions approximates the fair value of these assets since they generally involve limited losses from credit
risk or have short-term maturities with interest rates that approximate market.
Investments
Fair values of held-to-maturity securities are determined primarily using the same procedures described for
trading securities and available-for-sale securities aforementioned in this section. The fair values of other equity
interests, which primarily comprise non-marketable equity securities, are not readily determinable, and theircarrying amounts of ¥639 billion and ¥568 billion at March 31, 2009 and 2010, respectively, are not included in
the disclosure.
Loans
Performing loans have been fair valued as groups of similar loans based on the type of loan, credit quality,
prepayment assumptions and remaining maturity. The fair value of performing loans is estimated based on
discounted cash flows using interest rates approximating the MHFG Group’s current rates for similar loans,adjusting for inherent credit risk. The carrying amounts of impaired loans, net of allowance for loan losses,
approximate the fair values since allowance for loan losses for impaired loans is estimated based on an individual
basis to reflect the value of uncollectible amounts. During the fiscal year ended March 31, 2010, the Group haschanged the discounted cash flow methodologies and assumptions used for performing loans especially foradjusting inherent credit risk. There were no material impacts on the fair value of performing loans by suchchanges.
Other financial assets
The carrying value of other financial assets, such as accrued interest receivable and accounts receivable frombrokers, dealers, and customers for securities transactions, approximates the fair value of these assets since theygenerally involve limited losses from credit risk or have short-term maturities with interest rates that approximate
market.
Noninterest-bearing deposits, call money and funds purchased, and payables under repurchase agreements andsecurities lending transactions
The carrying value of short-term financial liabilities, such as noninterest-bearing deposits, call money and funds
purchased, and payables under repurchase agreements and securities lending transactions approximates the fairvalue of these liabilities since they generally have short-term maturities with interest rates that approximate
market.
Interest-bearing deposits
The carrying value of demand deposits approximates the fair value since it represents the amount payable on
demand at the balance sheet date. The fair value of time deposits and certificates of deposit is primarily estimatedbased on discounted cash flow analysis using current interest rates for instruments with similar maturities. The
carrying value of short-term certificates of deposit approximates the fair value.

Debentures
Debentures are fair valued using quoted market prices, if available. Otherwise, the fair value of debentures is
estimated based on discounted cash flow analysis using current interest rates for instruments with similar
maturities.
Due to trust accounts
The carrying value of due to trust accounts approximates the fair value since they generally have short-term
maturities with interest rates that approximate market.
Commercial paper and other short-term borrowings
The carrying value of the majority of short-term borrowings approximates the fair value since they generally
have short-term maturities with interest rates that approximate market. The fair value of certain borrowings isestimated based on discounted cash flow analysis using interest rates approximating the MHFG Group’s
incremental borrowings with similar maturities.
Long-term debt
Long-term debt is fair valued using quoted market prices, if available. Otherwise, the fair value of long-term debt
is estimated based on discounted cash flow analysis using interest rates approximating the MHFG Group’s
incremental borrowings with similar maturities. The valuation techniques of fair value of certain long-term debt
elected for fair value option under ASC 815-15-25 or ASC 825 are described separately in this section.
Other financial liabilities
The fair value of other financial liabilities, such as accrued interest payable and accounts payable to brokers,
dealers, and customers for securities transactions, approximates the carrying amounts.
The fair values of certain off-balance-sheet financial instruments, such as commitments to extend credit andcommercial letters of credit, are not considered material to the consolidated balance sheets at March 31, 2009 and2010.

31. Business segment information
Under U.S. GAAP, companies report segment information based on the way management disaggregates thecompany for making operating decisions. The MHFG Group’s operating segments are based on the nature of the
products and services provided, the type of customer and the Group’s management organization. The businesssegment information, set forth below, is derived from the internal management reporting systems used bymanagement to measure the performance of the Group’s business segments. The management measures theperformance of each of the operating segments primarily in terms of “net business profits” in accordance withinternal managerial accounting rules and practices. Net business profits is used as a measure of the profitabilityof core banking operations in Japan, and is defined as gross profits (or the sum of net interest income, fiduciaryincome, net fee and commission income, net trading income and net other operating income) less general andadministrative expenses (excluding non-recurring expenses). Measurement by net business profits is required forregulatory reporting to the FSA. Therefore, the format and information are presented primarily on the basis ofJapanese GAAP and are not consistent with the consolidated financial statements prepared in accordance with
U.S. GAAP. A reconciliation is provided for the segments’ total net business profits with Income (loss) before
income tax expense (benefit) under U.S. GAAP.
