MHFG is a holding company for Mizuho Bank, Ltd. (“MHBK”), Mizuho Trust & Banking Co., Ltd. (“MHTB”), Mizuho Securities Co., Ltd. (“MHSC”), Asset Management One Co., Ltd. (“Asset Management One”), and other subsidiaries. MHFG, through its subsidiaries (“the MHFG Group,” or “the Group”), provides domestic and international financial services in Japan and other countries. For a discussion of the Group’s segment information, see Note 20 “Business segment information.” MHFG and its domestic subsidiaries as well as its foreign subsidiaries maintain their accounting records in accordance with the accounting standards of Japan and those standards of the countries in which they are domiciled. Certain adjustments and reclassifications have been incorporated in the accompanying consolidated financial statements to conform them to 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. MHFG’s interim financial reporting period ends on September 30. Certain of MHFG’s subsidiaries have different interim financial reporting periods than September 30. For those subsidiaries with interim financial reporting periods within three months of MHFG’s interim financial reporting period, the effect of intervening events that materially affect the financial position or results of operations through the date of each of the periods presented in the MHFG’s consolidated financial statements have been considered for adjustment and/or disclosure. When determining whether to consolidate investee entities, the MHFG Group performs an analysis of the facts and circumstances of the particular relationships between the MHFG Group and the investee entities as well as the ownership of voting shares. The consolidated financial statements also include the accounts of VIEs for which MHFG or its subsidiaries have been determined to be the primary beneficiary in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, “Consolidation” (“ASC 810”). All significant intercompany transactions and balances have been eliminated upon consolidation. The MHFG Group accounts for investments in entities over which it has significant influence by 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 Equity in earnings (losses) of equity method investees-net. On October 1, 2020, a 1-for-10 The unaudited interim consolidated financial statements should be read in conjunction with the audited financial statements and related notes included in the MHFG Group’s most recent annual report on Form 20-F for the fiscal year ended March 31, 2021. Certain financial information that is normally included in annual financial statements prepared in accordance with U.S. GAAP, but is not required for interim reporting purposes, has been condensed or omitted. The financial statements reflect all normal and recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods. Use of estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make 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 the allowance for credit losses, valuation of deferred tax assets, valuation of derivative financial instruments, valuation of investments, valuation of certain long-term debt where the fair value option has been elected, valuation of pension and other employee benefits, and impairment of long-lived assets. During times of pandemics, such as COVID-19, Financial instruments—current expected credit losses (“CECL”) The adoption of this guidance established a single allowance framework for all financial assets measured at amortized cost and certain off-balance-sheet losses available-for-sale further impact Allowance and provision (credit) for credit losses on loans Effective April 1, 2020, the allowance for credit losses on loans is established for current expected credit losses on the MHFG Group’s loan portfolio in accordance with ASC 326. Additionally, as of April 1, 2020, the Group did not elect the fair value option for financial assets measured at amortized cost basis. Prior to April 1, 2020, the allowance for credit losses on loans was established The MHFG Group makes adjustments to the allowance for credit losses on loans through Provision (credit) for credit losses in the consolidated statements of income in each reporting period. Loan principal that management judges to be uncollectible, based on detailed loan reviews and a credit quality assessment, is charged off against the allowance for credit losses on loans. In general, the Group charges off loans when the Group determines that the obligor should be classified as substantially bankrupt or bankrupt. See Note 4 “Loans” for the definitions of obligor categories. Obligors in the retail portfolio segment are generally determined when they are past due for more than six months, and as for obligors in the corporate portfolio segment, the Group separately monitors the credit quality of each obligor without using time-based triggers. The MHFG Group maintains an appropriate allowance for credit losses on loans to represent management’s estimate of the expected credit losses in the Group’s loan portfolio. Management evaluates the appropriateness of the allowance for credit losses on loans semi-annually. The allowance considers expected credit losses over the remaining expected lives of the applicable ratings When determining expected credit losses, a single forward-looking macroeconomic scenario is considered over a reasonable and supportable forecast period. This forward-looking macroeconomic scenario is consistent to what is used in the MHFG Group’s stress testing and is in line with the scenario used for the Group’s business plan. If the scenario does not reflect a sudden change in economic conditions adequately, adjustments may be made to the scenario. After the forecast period, the Group reverts to long-term historical loss experience with a certain graduated transition period, to estimate losses over the remaining lives of financial assets measured at amortized cost and certain off-balance-sheet In terms of the internal risk ratings, for the corporate portfolio segment, the credit quality review process and the credit rating process serve as the basis for determining the allowance for credit losses on loans. 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, analysis of relevant industry segments and current trends. For the retail portfolio segment, the different categories of past due status of loans are primarily utilized in the credit quality review and the credit rating processes as the basis for determining the allowance for credit losses on loans. In general, the MHFG Group estimates expected credit losses collectively on the loans in the case of normal and watch obligors, considering the risk associated with a particular pool and the probability that the exposures within the pool will deteriorate or default. The allowance for credit losses on nonaccrual loans includes the allowance for groups of loans which were collectively evaluated for expected credit losses, in addition to the allowance for those loans that were individually evaluated for expected credit losses. See Note 4 “Loans” for the definitions of obligor categories and classification of nonaccrual loans. The estimation of expected credit losses that are evaluated collectively begins with a quantitative calculation that considers the likelihood of the borrower changing delinquency status or moving from one obligor category or rating to another. The quantitative calculation covers expected credit losses over an instrument’s expected life and is estimated by applying credit loss factors to the MHFG Group’s estimated exposure at default. The credit loss factors incorporate the probability of default as well as the loss given default based on the historical loss rates. To supplement the historical loss data for overseas obligors, external credit ratings such as S&P are also used evaluated collectively are analyzed on a periodic basis by comparing the estimated values with the actual results subsequent to the balance sheet date. The MHFG Group divides its overall portfolio into domestic and foreign portfolios and categorizes the domestic portfolio into four portfolio segments according to their risk profiles: corporate, retail, sovereign, and banks and financial institutions. The corporate portfolio segment consists of loans originated primarily by MHBK and MHTB, and includes mainly business loans such as those used for working capital and capital expenditure, as well as loans for which the primary source of repayment of the obligation is income generated by the relevant assets such as project finance, asset finance and real estate finance. The corporate portfolio segment is divided into two classes based on their risk characteristics: large companies, and small and medium-sized The retail portfolio segment consists mainly of residential mortgage loans originated by MHBK, and it is divided into two classes based on their risk characteristics: housing loan and others. For the retail portfolio segment, the Japanese unemployment rate is applied as a key factor. As it pertains to troubled debt restructuring (“TDR”) loans in the retail portfolio segment, the restructuring itself, as well as subsequent payment defaults, if any, are considered in determining obligor categories. Expected credit loss estimates also include consideration of expected cash recoveries on loans previously charged-off, The allowance recorded for individually evaluated loans is based on (1) the present value of expected future cash flows, after considering the restructuring effect and subsequent payment default with respect to TDRs, discounted at the loan’s initial effective interest rate, (2) the loan’s observable market price, or (3) the fair value of the collateral if the loan is collateral dependent. The collateral that the MHFG Group obtains for loans consists primarily of real estate. In obtaining the collateral, the Group evaluates the fair value of the collateral and its legal enforceability. The Group also performs subsequent re-evaluations The MHFG Group’s methodology for determining the appropriate allowance for credit losses on loans also considers the imprecision inherent in the methodologies used. As a result, the amounts determined under the methodologies described above could be adjusted by management to consider the potential impact of other qualitative factors which include, but are not limited to, imprecision in macroeconomic scenario assumptions and emerging risks related to changes in the environment that are affecting specific portfolio segments. Considering internal and external factors affecting the credit quality of the portfolio, the Group incorporated the estimated impact of COVID-19 Allowance and provision (credit) for credit losses on off-balance-sheet The MHFG Group maintains an allowance for credit losses on off-balance-sheet assesses the expected loss amounts for commitments to invest in securities and commitments to extend credit, considering the probability of drawdowns. The allowance is recorded in Other liabilities.

All Japanese agency mortgage-backed securities are issued by Japan Housing Finance Agency, a Japanese government-sponsored enterprise. At September 30, 2021, the MHFG Group did not intend to sell the debt securities in an unrealized loss position and it was not more likely than not that the Group would be required to sell them before the recovery of their amortized cost bases. For Japanese government bonds, U.S. Treasury bonds and federal agency securities and Agency mortgage-backed securities, their entire amortized cost bases were expected to be recovered since the unrealized losses had not resulted from credit deterioration, but primarily from changes in interest rates. For the debt securities other than those described above, except for the securities for which credit losses have been recognized in income, the Group determined that their entire amortized cost bases were expected to be recovered, after considering various factors such as the extent to which their fair values were below their amortized cost bases, the external and/or internal ratings and the present values of cash flows expected to be collected. Based on the aforementioned evaluation, except for the securities for which credit losses have been recognized in income, the Group determined that the debt securities in an unrealized loss position were not considered credit losses.

(2) Other industries of domestic includes trade receivables and lease receivables of consolidated VIEs. (3) Commercial and industrial of foreign includes ¥221,908 million and ¥221,144 million of lease receivables that are receivables arising from direct financing leasing at March 31, 2021 and September 30, 2021, respectively. (4) Banks and other financial institutions of foreign includes mainly banks and financial services companies. 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 over the 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 and discounts or premiums on purchased loans are deferred and recognized over the life of the loan using a method that approximates the interest method. Net losses on sales of loans were ¥1,178 million and ¥1,674 million for the six months ended September 30, 2020 and 2021, respectively. These net losses include unrealized gains and losses from making loans classified as held for sale to the lower of cost or fair value at the end of each reporting period. The gains and losses on sales of loans are recorded in Other noninterest income and expenses, respectively. Credit quality information In accordance with the MHFG Group’s credit risk management policies, the Group uses an internal rating system that consists of credit ratings for the corporate portfolio segment and pool allocations for the retail portfolio segment as the basis of its risk management infrastructure. Credit ratings consist of obligor ratings which represent the level of credit risk of the obligor, and transaction ratings which represent the ultimate possibility of losses expected on individual loans by taking into consideration various factors such as collateral or guarantees involved. In principle, obligor ratings are applied to all obligors except those to which pool allocations are applied and are subject to regular review at least once a year as well as special review which is required whenever the obligor’s credit standing changes. Pool allocations are applied to small loans that are less than a specified amount by pooling customers and loans with similar risk characteristics, and the risk is assessed mainly based on past due status and managed according to such pools. The Group generally reviews the appropriateness and effectiveness of the approach to obligor ratings and pool allocations once a year in accordance with predetermined policies and procedures. The Group does not record expected credit losses for accrued interest receivables because uncollectible accrued interest is reversed through interest income in a timely manner in line with the Group’s nonaccrual and past due policies for loans. The amount of accrued interest receivables at September 30, 2021 was ¥73,807 million and included in Accrued income. The table below presents credit quality information of loans based on the MHFG Group’s internal rating system at March 31, 2021 and September 30, 2021: Obligor category (1)(2) Obligor rating Definition Normal A Obligors whose certainty of debt fulfillment is very high, hence their level of credit risk is very low. B Obligors whose certainty of debt fulfillment poses no problems for the foreseeable future, and their level of credit risk is low. C Obligors whose certainty of debt fulfillment and their level of credit risk pose no problems for the foreseeable future. D Obligors whose current certainty of debt fulfillment poses no problems, however, their resistance to future economic environmental changes is low. Watch E1 Obligors that require observation going forward because of either minor concerns regarding their financial position, or their somewhat weak or unstable business conditions. E2 Obligors that require special observation going forward because of problems with their borrowings such as reduced or suspended interest payments, problems with debt fulfillment such as failure to make principal or interest payments, or problems with their financial position as a result of their weak or unstable business conditions. Intensive control F Obligors that are not yet bankrupt but are in financial difficulties and are deemed likely to become bankrupt in the future because of insufficient progress in implementing their management improvement plans or other measures (including obligors that are receiving ongoing support from financial institutions). Substantially bankrupt G Obligors that have not yet become legally or formally bankrupt but are substantially insolvent because they are in serious financial difficulties and are deemed to be incapable of being restructured. Bankrupt H Obligors that have become legally or formally bankrupt. Notes: (1) Special attention obligors are watch obligors with debt in TDR or 90 days or more delinquent debt. Loans to such obligors are considered nonaccrual. (2) The Group classifies loans to special attention, intensive control, substantially bankrupt and bankrupt obligors as nonaccrual loans.

90 days or more delinquent debt. Loans to such obligors are considered nonaccrual. (2) The primary component of the retail portfolio segment is housing loans to individuals which obligor category is classified based on past due status. The trigger to reclassify obligors from normal obligors to watch obligors excluding special attention obligors is when the past due status is more than 30 days. (3) There were no significant revolving line of credit arrangements that converted to term loans during the six months ended September 30, 2021. (4) Banks and other financial institutions of domestic includes mainly banks and securities companies (5) Banks and other financial institutions of foreign includes mainly banks. Nonaccrual loans Loans are considered nonaccrual 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 the contractual terms of the loans. Factors considered by management in determining if a loan is nonaccrual include delinquency status and the ability of the debtor to make payment of the principal and interest when due. The Group classifies loans to special attention, intensive control, substantially bankrupt and bankrupt obligors as nonaccrual loans. Nonaccrual loans include loans past due for 90 days or more and restructured loans that meet the definition of a TDR in accordance with ASC 310. There are no loans that are 90 days past due and still accruing. The Group does not have any loans to borrowers that cause management to have serious doubts as to the ability of such borrowers to comply with the present In March 2020, the Coronavirus, Aid, Relief, and Economic Security Act (“the CARES Act”) was approved. The CARES Act and U.S. banking agencies have among other items, provided optional, temporary relief related to accounting for certain TDRs. The temporary TDR relief is available to banks for loan modifications related to obligors who were adversely impacted by COVID-19. With regard to nonaccrual loans, interest accruals and the amortization of net origination fees are suspended, and capitalized interest is written off. Cash received on nonaccrual loans is accounted for as a reduction of the loan principal if the ultimate collectability of the principal amount is in doubt, otherwise, as interest income. Loans are not restored to accrual status until interest and principal payments are current and future payments are reasonably assured. Nonaccrual loans are restored to accrual status, when the MHFG Group determines that the borrower poses no concerns regarding current certainty of debt fulfillment. In general, such determination is made if the borrower qualifies for an obligor rating of E2 or above and is not classified as a special attention obligor. With respect to loans restructured in a TDR, in general, such loans are restored to accrual status, when the borrower qualifies for an obligor rating of D or above.

Troubled debt restructurings The MHFG Group considers a loan modification to be a TDR when, for economic or legal reasons related to the obligor’s financial difficulties, it grants a concession to the obligor that it would not otherwise consider. The Group considers the relevant obligor to be in financial difficulty generally when its obligor rating is E2 or below.

Loans held for sale Loans that have been identified for sale are classified as loans held for sale within O Collateral Dependent Loans The MHFG Group uses, as a practical expedient, the fair value of the collateral when recording the net carrying amounts of loans and determining the allowance for credit losses of such loans, for which the repayment is expected to be provided substantially through the operation or sale of the collateral, when the borrower is experiencing financial difficulty based on the assessment as of the reporting date. As of September 30, 2021, collateral relating to these loans comprised of real estate, exchange traded equity securities and deposits, etc., and primarily collateral type was real estate. There were no significant changes in the extent to which collateral secures these loans during this fiscal year and no significant concentration of collateral against any portfolio segment. |

Allowance for credit losses on loans | 5. Allowance for credit losses on loans The MHFG Group divides its overall portfolio into domestic and foreign portfolios, and categorizes the domestic portfolio into four portfolio segments according to their risk profiles: corporate, retail, sovereign, and banks and financial institutions. When management estimates current expected credit losses to determine the allowance for credit losses, small balance, homogeneous loans are classified in the retail portfolio segment, and loans other than these are classified in the corporate portfolio segment. The corporate portfolio segment consists of loans originated primarily by MHBK and MHTB, and includes mainly business loans such as those used for working capital and capital expenditure, as well as loans for which the primary source of repayment of the obligation is income generated by the relevant assets such as project finance, asset finance and real estate finance. The corporate portfolio segment also includes loans of subsidiaries other than MHBK and MHTB, such as consolidated VIEs and overseas subsidiaries. The corporate portfolio segment is divided into two classes based on their risk characteristics: large companies, and small and medium-sized Changes in Allowance for credit losses on loans by portfolio segment for the six months ended September 30, 2020 and 2021 are shown below: Corporate Retail Total (in millions of yen) Six months ended September 30, 2020 Balance at beginning of period 413,026 27,829 440,855 April 1, 2020 adoption of CECL 77,514 78,241 155,755 Adjusted Balance at beginning of period 490,540 106,070 596,610 Provision (credit) for credit losses on loans 64,133 (11,051 ) 53,082 Charge-offs (28,417 ) (3,446 ) (31,863 ) Recoveries 5,260 479 5,739 Net charge-offs (23,157 ) (2,967 ) (26,124 ) Others (Note) (997 ) (45 ) (1,042 ) Balance at end of period 530,519 92,007 622,526 Six months ended September 30, 2021 Balance at beginning of period 562,470 88,379 650,849 Provision (credit) for credit losses on loans 49,695 (1,490 ) 48,205 Charge-offs (38,473 ) (2,423 ) (40,896 ) Recoveries 5,827 664 6,491 Net charge-offs (32,646 ) (1,759 ) (34,405 ) Others (Note) 579 — 579 Balance at end of period 580,098 85,130 665,228 Note: Others includes primarily foreign exchange translation. |

Regulatory matters Regulatory capital requirements MHFG, MHBK, and MHTB are subject to regulatory capital requirements administered by the Financial Services Agency in accordance with the provisions of Japan’s Banking Act and related regulations. Certain foreign banking subsidiaries are subject to regulation and control by local supervisory authorities, including central banks. Capital adequacy ratios and leverage ratios of MHFG, MHBK, and MHTB as of March 31, 2021 and September 30, 2021 calculated in accordance with Japanese GAAP and the guidelines established by the Financial Services Agency are set forth in the following table: March 31, 2021 September 30, 2021 Amount Ratio Amount Ratio (in billions of yen, except percentages) Consolidated: MHFG: Common Equity Tier 1 capital: Required (1) 5,405 8.01 5,379 8.01 Actual 7,850 11.63 8,244 12.27 Tier 1 capital: Required (1) 6,418 9.51 6,386 9.51 Actual 9,702 14.37 10,098 15.03 Total risk-based capital: Required (1) 7,767 11.51 7,729 11.51 Actual 11,385 16.87 11,927 17.76 Leverage Ratio (2) Required 6,016 3.00 6,108 3.00 Actual 9,702 4.83 10,098 4.96 MHBK: Common Equity Tier 1 capital: Required 2,823 4.50 2,794 4.50 Actual 6,972 11.11 7,340 11.82 Tier 1 capital: Required 3,764 6.00 3,726 6.00 Actual 8,819 14.05 9,187 14.79 Total risk-based capital: Required 5,019 8.00 4,967 8.00 Actual 10,400 16.57 10,924 17.59 Leverage Ratio (2) Required 5,660 3.00 5,700 3.00 Actual 8,819 4.67 9,187 4.83 MHTB: Common Equity Tier 1 capital: Required 82 4.50 81 4.50 Actual 527 28.94 479 26.70 Tier 1 capital: Required 109 6.00 108 6.00 Actual 527 28.94 479 26.70 Total risk-based capital: Required 146 8.00 144 8.00 Actual 527 28.94 479 26.71 Leverage Ratio (2) Required 138 3.00 129 3.00 Actual 527 11.41 479 11.17 March 31, 2021 September 30, 2021 Amount Ratio Amount Ratio (in billions of yen, except percentages) Non-consolidated: MHBK: Common Equity Tier 1 cap i Required 2,648 4.50 2,619 4.50 Actual 6,561 11.14 6,790 11.66 Tier 1 capital: Required 3,531 6.00 3,492 6.00 Actual 8,406 14.28 8,635 14.83 Total risk-based capital: Required 4,708 8.00 4,656 8.00 Actual 9,987 16.96 10,355 17.79 Leverage Ratio (2) Required 5,343 3.00 5,373 3.00 Actual 8,406 4.72 8,635 4.82 MHTB: Common Equity Tier 1 capital: Required 82 4.50 80 4.50 Actual 519 28.63 465 26.03 Tier 1 capital: Required 109 6.00 107 6.00 Actual 519 28.63 465 26.03 Total risk-based capital: Required 145 8.00 143 8.00 Actual 519 28.64 465 26.04 Leverage Ratio (2) Required 135 3.00 125 3.00 Actual 519 11.51 465 11.15 Notes: (1) The required ratios disclosed above, at March 31, 2021 and September 30, 2021, include the capital conservation buffer of 2.5%, the countercyclical capital buffer of 0.01%, and the additional loss absorbency requirements for global systemically important banks (“G-SIBs”) (“D-SIBs”) (2) The required and actual amounts disclosed above at March 31, 2021 and September 30, 2021 exclude amounts of deposits to the Bank of Japan. MHFG’s securities subsidiary in Japan is also subject to the capital adequacy requirement under Japan’s Financial Instruments and Exchange Act. Failure to maintain a minimum capital ratio will trigger mandatory regulatory actions. Management believes, as of each latest balance sheet date, that MHFG, MHBK, MHTB, and their securities subsidiary in Japan and foreign banking subsidiaries were in compliance with all capital adequacy requirements to which they were subject. Business improvement orders In September and November 2021, MHFG and MHBK received business improvement orders from the Financial Services Agency of Japan, pursuant to the provisions of Article 52-33, Paragraph 1 and Article 26, Paragraph 1 of the Banking Act of Japan, in regard to the series of IT system failures that have occurred from February to September 2021. MHFG and MHBK has been and will be formulating and implementing the business improvement plans and measures so that further similar incidents will be prevented. See Note 14 “Commitments and contingencies” for further information on the impact that these orders have on the consolidated financial statements. |

Earnings per common share | 10. Earnings per common share Basic earnings per common share are computed by dividing net income attributable to MHFG common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share reflect all dilutive potential common shares such as stock options and the common shares of MHFG under the stock compensation programs. The following table sets forth the computation of basic and diluted earnings per common share for the six months ended September 30, 2020 and 2021: Six months ended September 30, 2020 2021 (in millions of yen) Net income: Net income attributable to MHFG common shareholders 315,886 312,657 Effect of dilutive securities — — Net income attributable to common shareholders after assumed conversions 315,886 312,657 Six months ended September 30, 2020 2021 (thousands of shares) Shares: Weighted average common shares outstanding 2,537,272 2,536,902 Effect of dilutive securities: Stock options and the common shares of MHFG under the stock compensation programs (Note) 93 119 Weighted average common shares after assumed conversions 2,537,365 2,537,021 Six months ended September 30, 2020 2021 (in yen) Earnings per common share: Basic net income per common share 124.50 123.24 Diluted net income per common share (Note) 124.49 123.24 Note: For the six months ended September 30, 2020, the performance-based plan under the stock compensation programs could potentially dilute earnings per common share but were not included in the computation of diluted earnings per common share due to their antidilutive effects. |

Income taxes | 11. Income taxes The following table presents the components of Income tax expense for the six months ended September 30, 2020 and 2021: Six months ended 2020 2021 (in millions of yen) Current tax expense 79,954 67,822 Deferred tax expense (benefit) 57,807 (28,200 ) Total income tax expense 137,761 39,622 The preceding table does not reflect the tax effects of items recorded directly in Equity for the six months ended September 30, 2020 and 2021. The detailed amounts recorded directly in Equity are as follows: Six months ended 2020 2021 (in millions of yen) Net unrealized gains (losses) on available-for-sale Unrealized gains (losses) 579 926 Less: reclassification adjustments 306 (213 ) Total 885 713 Pension liability adjustments: Unrealized gains (losses) 83,994 (2,144 ) Less: reclassification adjustments 321 (3,875 ) Total 84,315 (6,019 ) Own credit risk adjustments: Unrealized gains (losses) (2,351 ) (2,638 ) Less: reclassification adjustments (1,259 ) 219 Total (3,610 ) (2,419 ) Total tax effect before allocation to noncontrolling interests 81,590 (7,725 ) The statutory tax rates were both 30.62% as of September 30, 2020 and 2021. The effective tax rates, 25.15% and 10.34 % for the six months ended September 30, 2020 and 2021, respectively, differed from the statutory tax rates. The difference of the tax rates for the six months ended September 30, 2020 resulted mainly from the effect of noncontrolling interest income of consolidated VIEs. The significant difference of the tax rate for the six months ended September 30, 2021 resulted mainly from the reversal of an outside basis difference related to the share buyback conducted by MHSC in response to improving the capital position and aligning to the MHFG Group’s capital policy, and was partially offset by an increase in the valuation allowance. At September 30, 2021, the MHFG Group had net operating loss carryforwards totaling ¥788 billion. The total amount of unrecognized tax benefits was ¥4,492 million at September 30, 2021, which would, if recognized, affect the Group’s effective tax rate. The Group classifies interest and penalties accrued relating to unrecognized tax benefits as Income tax expense. A portion of unrecognized tax benefits at March 31, 2021 was resolved in the six months period ended September 30, 2021, of which the amount was immaterial. The amount of additional unrecognized tax benefits for the period related to the tax positions taken was also immaterial. 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. |

In accordance with ASC 715, “Compensation—Retirement Benefits” (“ASC 715”), any change in projected benefit obligations due to a plan amendment is required to be recognized as prior service benefits (cost) as of the amendment date. Accordingly, the MHFG Group recognized ¥73,998 million of prior service benefits for the six months ended September 30, 2020. |

Derivative financial instruments | 13. Derivative financial instruments The MHFG Group enters into derivative financial instruments in response to the diverse needs of customers, to manage the risk related to the assets and liabilities of the Group, as part of its asset and liability management, and for proprietary trading purposes. The 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 or indices, interest rates and foreign exchange rates that may result in an adverse change in the market value of the financial 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 Group is exposed to credit risk associated with counterparty default or nonperformance in respect of transactions. Counterparty credit risk arises when a counterparty fails to perform according to the terms and conditions of the contract and the value of the underlying collateral held, if applicable, is not sufficient to recover resulting losses. The exposure to counterparty credit risk is measured by the fair value of all derivatives and its potential exposure at the balance sheet dates. The exposure to counterparty credit risk is managed by entering into legally enforceable master netting agreements to mitigate the overall counterparty credit risk, requiring underlying collateral and guarantees based on an individual credit analysis of each obligor and evaluating the credit features of each instrument. In addition, credit approvals, limits and monitoring procedures are also imposed. Notional and fair value amounts of derivative instruments The following table summarizes the notional and fair value amounts of derivative instruments outstan d Fair value Derivative receivables (2) Derivative payables (2) March 31, 2021 Notional amount (1) Designated as hedges Not designated as hedges Designated as hedges Not designated as hedges (in billions of yen) Interest rate contracts 1,174,835 — 4,639 — 4,476 Foreign exchange contracts 182,809 — 3,328 — 3,246 Equity-related contracts 7,865 — 531 — 384 Credit-related contracts 10,431 — 94 — 113 Other contracts 413 — 33 — 33 Total 1,376,353 — 8,625 — 8,252 Fair value Derivative receivables (2) Derivative payables (2) September 30, 2021 Notional amount (1) Designated as hedges Not designated as hedges Designated as hedges Not designated as hedges (in billions of yen) Interest rate contracts 1,061,161 — 3,404 — 3,245 Foreign exchange contracts 192,620 — 2,487 — 2,383 Equity-related contracts 9,782 — 495 — 328 Credit-related contracts 11,478 — 116 — 136 Other contracts 528 — 63 — 65 Total 1,275,569 — 6,565 — 6,157 Notes: (1) Notional amount includes 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 agreements. The cash collateral, which was not offset against derivative positions, was included in Other assets and Other liabilities, respectively, of which the amounts were ¥1,108 billion and ¥764 billion at March 31, 2021, and ¥900 billion and ¥722 billion at September 30, 2021, 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 documentation of 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. The MHFG Group’s hedging activities include net investment hedges. 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 The following table summarizes gains and losses information related to net investment hedges for the six months ended September 30, 2020 and 2021: Gains (losses) recorded in other for six months ended September 30, 2020 2021 (in millions of yen) Financial instruments hedging foreign exchange risk 1,538 (1,241 ) Total 1,538 (1,241 ) Note: No amount related to the net investment hedges was reclassified from Accumulated other comprehensive income to earnings for the six months ended September 30, 2021. Related to the net investment hedges, gains (losses) of ¥(1,312) million was reclassified from Accumulated other comprehensive income to earnings for the six months ended September 30, 2020. Derivative instruments not designated or qualifying as hedges The MHFG Group enters into the following derivative transactions that do not qualify for hedge accounting with a view to implementing risk management strategies: (1) interest-rate swap transactions for the purpose of economically managing the interest-rate risks in deposits, loans , The following table summarizes gains and losses on derivatives not designated or qualifying as hedges during the six months ended September 30, 2020 and 2021: Gains (losses) recorded in income for six months ended September 30, 2020 2021 (in millions of yen) Interest rate contracts 32,791 20,602 Foreign exchange contracts 26,277 7,407 Equity-related contracts (31,999 ) 33,504 Credit-related contracts (Note) (29,219 ) (15,599 ) Other contracts 26,692 6,875 Total 24,542 52,789 Note: Amounts include the net gains (losses) of ¥(1,221) million and ¥(395) million on the credit derivatives economically managing the cr e Credit derivatives A credit derivative is a bilateral contract between a seller and a buyer of protection against the credit risk of a particular entity. Credit derivatives generally require that the seller of credit protection make payments to the buyer 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 a portfolio of reference credits. The Group enters into credit derivatives to help mitigate credit risk in its corporate loan 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 the related cash flows, while being liable for the full notional amount of credit protection to the buyer. The Group manages credit risk associated with written protection by purchasing protection with identical or similar underlying reference credits, which substantially offsets its exposure. Thus, the notional amount is not necessarily a reliable indicator of the Group’s actual loss exposure. The following table summarizes the notional and fair value amounts of credit derivatives at March 31, 2021 and September 30, 2021: March 31, 2021 September 30, 2021 Notional amount Fair value Notional amount Fair value (in billions of yen) Credit protection written: Investment grade 3,687 71 4,150 86 Non-investment 872 17 916 22 Total 4,559 88 5,066 108 Credit protection purchased 5,872 (107 ) 6,412 (128 ) Note: The rating scale is based upon either the external ratings or the internal ratings of the underlying reference credit.

If the Group’s debt credit rating 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 which are in net liability positions for the Group.

Commitments and contingencies | 14. Commitments and contingencies Obligations under guarantees The MHFG Group provides guarantees or indemnifications to counterparties to enhance their credit standing and enable them to complete a variety of business transactions. A guarantee represents an obligation to make payments to third parties if the counterparty fails to fulfill its obligation under a borrowing arrangement or other contractual obligation. The Group records all guarantees and similar obligations subject to ASC 460, “Guarantees” (“ASC 460”) at fair value in the consolidated balance sheets at the inception of the guarantee. The table below summarizes the maximum potential amount of future payments by type of guarantee at March 31, 2021 and September 30, 2021.

Variable interest entities and securitizations | 15. 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 types of transactions: asset-backed commercial paper/loan programs, asset-backed securitizations, investments in securitization products, investment funds, trust arrangements, structured finance, and funding vehicles. The Group consolidates certain of these VIEs, where the Group is deemed to be the primary beneficiary because it has both (1) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (2) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The MHFG Group reassesses whether it is the primary beneficiary on an ongoing basis as long as the Group has any continuing involvement with the VIE. There are also other VIEs, where the Group has determined that it is not the primary beneficiary but has significant variable interests. In evaluating the significance of the variable interests, the Group 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 other relevant facts and circumstances. The likelihood of loss is not necessarily relevant to the determination of significance, and therefore, “significant” does not imply that there is high likelihood of loss. The maximum exposure to loss that is discussed in this section refers to the maximum loss that the Group could possibly be required to record in its consolidated statements of income as a result of its involvement with the VIEs. This represents exposures associated with both on-balance-sheet off-balance-sheet The table below shows the consolidated assets of the Group’s consolidated VIEs as well as total assets and maximum exposure to loss for its significant unconsolidated VIEs, in which the Group has determined that its maximum exposure to loss is greater than specific thresholds or meets certain other criteria as of March 31, 2021 and September 30, 2021: Consolidated VIEs Significant unconsolidated VIEs March 31, 2021 Consolidated assets Total assets Maximum exposure to (in billions of yen) Asset-backed commercial paper/loan programs 2,628 — — Asset-backed securitizations 921 127 48 Investments in securitization products 390 — — Investment funds 2,299 3,219 768 Trust arrangements and other 5,535 — — Total 11,773 3,346 816 Consolidated VIEs Significant unconsolidated VIEs September 30, 2021 Consolidated assets Total assets Maximum exposure to (in billions of yen) Asset-backed commercial paper/loan programs 2,537 — — Asset-backed securitizations 1,198 138 57 Investments in securitization products 394 — — Investment funds 2,146 3,052 716 Trust arrangements and other 5,525 — — Total 11,800 3,190 773 As of March 31, 2021 and September 30, 2021, the noncontrolling interests in consolidated VIEs amounted to ¥464 billion and ¥564 billion, respectively, and are included in the Group’s equity-classified noncontrolling interests. The Group has not provided financial or other support to consolidated or unconsolidated VIEs that the Group was not previously contractually required to provide. The tables below present the carrying amounts and classification of assets and liabilities on the MHFG Group’s balance sheets that relate to its variable interests in significant unconsolidated VIEs, as of March 31, 2021 and September 30, 2021: Assets on balance sheets related to unconsolidated VIEs: March 31, 2021 September 30, 2021 (in billions of yen) Trading account assets 127 130 Investments 513 464 Loans 66 68 Total 706 662 Liabilities on balance sheets and maximum exposure to loss related to unconsolidated VIEs: March 31, 2021 September 30, 2021 (in billions of yen) Payables under securities lending transactions 53 55 Trading account liabilities 2 2 Total 55 57 Maximum exposure to loss (Note) 816 773 Note: This represents the maximum amount the Group could possibly be required to record in its consolidated statements of income associated with on-balance-sheet off-balance-sheet In the table above the nature of the Group’s variable interest can take different forms, as described further in the notes below. Additionally the Group’s exposure to the obligations of VIEs is generally limited to its interest in these entities. In certain instances the Group provides undrawn commitments to the VIEs. The Group’s maximum exposure to loss presented in the table above does not include the benefit of offsetting financial instruments that are held to mitigate the risks associated with these variable interests. Furthermore, the Group’s maximum exposure to loss presented in the table above is not reduced by the amount of collateral held as part of the transaction with the VIE or any party to the VIE directly against a specific exposure to loss. Asset-backed commercial paper/loan programs The MHFG Group manages several asset-backed commercial paper/loan programs that provide its clients with off-balance-sheet market 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 has the power to determine which assets will be held by the VIEs and has an obligation to monitor these assets. The Group is also responsible for liability management. In addition, through the liquidity and credit support facilities provided to the VIEs, the Group has the obligation to absorb losses that could potentially be significant to the VIEs. Therefore, the Group consolidates such VIEs. Asset-backed securitizations The MHFG Group acts as an arranger of various types of structured finance schemes to meet its clients’ needs for off-balance-sheet 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 meet clients’ 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 in debt and equity instruments. In these cases, the MHFG Group consider s off-balance The MHFG Group established certain VIEs to securitize its own mortgage loans. The Group provides servicing for and holds retained subordinated beneficial interests in the securitized mortgage loans. In addition, the Group retains credit exposure in the form of guarantees on these loans. In its role as a servicer, the Group has the power to direct the entity’s activities that most significantly impact the entity’s economic performance by managing defaulted mortgage loans. In addition, through its retained interests and its aforementioned involvement as a guarantor, the Group has the obligation to absorb losses and the right to receive benefits that could potentially be significant to the entity. Therefore, the Group consolidates such VIEs. The MHFG Group started Tender Option Bond (“TOB”) programs in the fiscal year ended March 31, 2020, which are associated with trusts that hold highly-rated, fixed-rate and tax-exempt non-customer non-customer Both types of TOB trusts are deemed to be VIEs because its equity holder does not have decision making rights. The MHFG Group considers that it is a “significant” variable interest when the Group has the residuals as a sponsor and/or provides liquidity and credit support facilities. The Group often commits to provide liquidity to customer TOB trusts and the residual holders of customer TOB trusts are obligated to reimburse the Group for any payment the Group makes under those liquidity and credit support facilities. In non-customer Investments in securitization products The MHFG Group invests in, among other things, va r CLO 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, administer and make investment decisions about such investment funds. The Group considers that it is a “significant” variable interest when the Group’s investment share is greater than threshold. The Group consolidates certain investment funds where it is deemed to be the primary beneficiary. The Group determines whether it is the primary beneficiary by evaluating whether it has both (1) the power to make investment decisions about the investment funds and (2) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the 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 by and transferred to third parties. The Group receives trust fees for providing services as an agent or fiduciary on behalf of beneficiaries. In these cases, the MHFG Group considers that these variable interests are not significant except for its specific involvement as noted below; With respect to guaranteed principal money trust products, the MHFG consolidates With respect to non-guaranteed non-guaranteed The MHFG Group has established a trust in August 2020, which holds the Group’s housing loans and in turn issues beneficiary interests to the Group, as a result from Special Funds-Supplying Operations implemented by the Bank of Japan to facilitate financing in response to COVID-19. 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 and financing in securitized receivable. As the Group typically only provides senior financing with credit enhanced by subordinated interests and may sometimes act as an interest rate swap counterparty, the Group has determined that it does not have the power to direct the activities of the VIEs that most significantly impact the VIEs’ economic performance, or it does not have significant variable interests. Therefore, the Group does not consolidate such VIEs. Funding Vehicles The MHFG Group has established several wholly-owned off-shore sufficient equity to finance their activities; however, the MHFG Group’s investment in the vehicles’ equity is not a variable interest because the investment is not considered to be at risk as the entire amount raised by the vehicles was used to purchase debt instruments issued by the MHFG Group. Because the MHFG Group does not have variable interests in these vehicles, the MHFG Group does not consolidate these entities. Debt instruments issued by the MHFG Group, which are included in Long-term debt, were ¥332 billion and ¥336 billion at March 31, 2021 and September 30, 2021, respectively. Securitization The MHFG Group engages in securitization activities and securitizes mortgage loans, other loans, government and corporate securities and other types of financial assets in the normal course of business. In these securitization transactions, the Group records the transfer of a financial asset as a sale when all the accounting criteria for a sale under ASC 860, “Transfers and Servicing” (“ASC860”) are met. These criteria are (1) the transferred financial assets are legally isolated from the Group’s creditors, (2) the transferee or beneficial interest holder has the right to pledge or exchange the transferred financial assets, and (3) the Group does not maintain effective control over the transferred financial assets. If all the criteria are not met, the transfer is accounted for as a secured borrowing. For the six months ended September 30, 2020 and 2021, the MHFG Group neither made significant transfers of financial assets nor recognized significant gains or losses in securitization transactions accounted for as sales. The Group did not retain significant interests in securitization transactions accounted for as sales as of March 31, 2021 and September 30, 2021. There are certain transactions where transfers of financial assets do not qualify for the aforementioned sales criteria and are accounted for as secured borrowings. These transferred assets continue to be carried on the consolidated balance sheets of the MHFG Group. Such assets are associated with securitization transactions and loan participation transactions, which amounted to ¥176 billion and ¥181 billion as of March 31, 2021, and ¥153 billion and ¥179 billion as of September 30, 2021, respectively. Liabilities associated with securitization and loan participation transactions are presented as Payables under securities lending transactions and Other short-term borrowings or Long-term debt, respectively, on the consolidated balance sheets. |

Fair value

Fair value | 17. Fair value Fair value measurements ASC 820, “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 when measuring fair value. In addition, ASC 820 precludes (1) the deferral of gains and losses at inception of certain derivative contracts whose fair value was not evidenced by market-observable data, and (2) the 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 fair value: Level 1 Quoted prices in active markets for identical assets or liabilities. Level 1 assets and liabilities include debt and equity securities and derivative contracts that are traded in an active exchange market. Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments. If no quoted market prices are available, the fair values of debt securities and over-the-counter Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Valuation process The MHFG Group has established valuation policies which govern the principles of fair value measurements and the authority and duty of each department. The Group has also established procedure manuals which describe valuation techniques and related inputs for determining the fair values of various financial instruments. The policies require that the measurement of fair values be carried out in accordance with the procedures performed by the risk management departments or the back offices which are independent from the front offices. The policies also require the risk management departments to check and verify whether the valuation methodologies defined in the procedure manuals are fair and proper and the internal audit departments to periodically review the compliance with the procedures throughout the Group. Although the valuation methodologies and related inputs are consistently used from period to period, a change in the market environment sometimes leads to a change in the valuation methodologies and the inputs. For instance, a change in market liquidity due to a delisting or a new listing is one of the key drivers of revisions to the valuation methodologies and the inputs. The key drivers also include the availability or the lack of market observable inputs and the development of new valuation methodologies. Price verification performed through the Group’s internal valuation process has an important role in identifying whether the valuation methodologies and the inputs need to be changed. The internal valuation process over the prices broker-dealers provide, primarily for Japanese securitization products, is described in more detail below in Available-for-sale The following is a description of valuation methodologies and inputs used for assets and liabilities measured at fair value on a recurring basis, including the general classification of such instruments pursuant to the fair value hierarchy and the MHFG Group’s valuation techniques used to measure fair values. During the six months ended September 30, 2021, there were no significant 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 to measure the 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 equity securities. When quoted prices for identical securities are available, but not actively traded, such securities are classified in Level 2 of the fair value hierarchy. When no quoted market prices are available, the Group estimates fair values by using pricing models with 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 liquid market conditions exist for securities, the quoted prices are stale or the prices from independent sources vary significantly, such securities are generally classified in Level 3 of the fair value hierarchy. The fair values of securitization products such as RMBS, CMBS, ABS, and CLO are determined primarily by using a discounted cash flow model. The key inputs used for the model include default rates, recovery rates, prepayment rates, and discount rates. In the event that certain key inputs are unobservable or cannot be corroborated by observable market data, these financial instruments are classified in Level 3. Hedge funds the Group invests in are primarily multi strategy funds that employ a fundamental bottom-up start-up ten-year Derivative financial instruments Exchange-traded derivatives are valued using quoted market prices and consequently are classified in Level 1 of the fair value hierarchy. However, the majority of derivatives entered into by the Group are executed over-the-counter over-the-counter severity factors that are developed from market credit spreads and other related market information. Also, the Group records funding valuation adjustments to reflect the impact of funding on uncollateralized over-the-counter Available-for-sale The fair values of available-for-sale non-binding Equity securities Equity securities mainly consist of marketable equity securities. The fair values of the marketable equity securities are based upon quoted market prices for identical equity securities trading as securities in an active market. Equity securities also include investments in certain investment funds measured using the NAV per share practical expedient including private equity funds and real estate funds. These securities are determined primarily using the same procedures described under Trading securities and trading securities sold, not yet purchased Other investments Other investments consist of investments held by consolidated investment companies. These companies typically hold investments in marketable and non-marketable non-marketable such securities, the Group firstly considers recent market transactions of identical securities, if applicable. Thereafter, the Group uses commonly accepted valuation techniques such as earnings multiples based on comparable public securities. Non-marketable Long-term debt Fair value accounting is elected for certain long-term debt instruments with embedded derivatives. The fair values are determined using a discounted cash flow model that considers the embedded derivatives and the terms and payment structures of the notes. The fair values of the derivatives embedded in such notes are primarily derived by using the same procedures described in Derivative financial instruments Items measured at fair value on a recurring basis Assets and liabilities measured at fair value on a recurring basis at March 31, 2021 and September 30, 2021, including those for which the MHFG Group has elected the fair value option, are summarized below: March 31, 2021 Level 1 Level 2 Level 3 Assets/ Liabilities measured at fair value (in billions of yen) Assets: Trading securities (1) Japanese government bonds 1,923 11 — 1,934 Japanese local government bonds — 120 — 120 U.S. Treasury bonds and federal agency securities 3,544 604 — 4,148 Other foreign government bonds 775 500 — 1,275 Agency mortgage-backed securities — 4,727 — 4,727 Residential mortgage-backed securities — — 9 9 Certificates of deposit and commercial paper — 1,204 — 1,204 Corporate bonds and other (2) 34 1,638 1,033 2,705 Equity securities 1,220 326 29 1,575 Trading securities measured at net asset value (3) 431 Derivative financial instruments: Interest rate contracts 63 4,564 12 4,639 Foreign exchange contracts — 3,304 24 3,328 Equity-related contracts 170 339 22 531 Credit-related contracts — 91 3 94 Other contracts 10 6 17 33 Available-for-sale Japanese government bonds 20,598 323 — 20,921 Japanese local government bonds — 463 — 463 U.S. Treasury bonds and federal agency securities 911 — — 911 Other foreign government bonds 535 972 — 1,507 Agency mortgage-backed securities — 521 — 521 Residential mortgage-backed securities — 48 23 71 Commercial mortgage-backed securities — — 716 716 Japanese corporate bonds and other debt securities — 1,539 365 1,904 Foreign corporate bonds and other debt securities — 707 132 839 Equity securities: Equity securities with readily determinable fair values 3,375 104 — 3,479 Equity securities measured at net asset value (3) 121 Other investments 2 — 53 55 Total assets measured at fair value on a recurring basis 33,160 22,111 2,438 58,261 Liabilities: Trading securities sold, not yet purchased 2,138 488 — 2,626 Derivative financial instruments: Interest rate contracts 64 4,408 4 4,476 Foreign exchange contracts — 3,245 1 3,246 Equity-related contracts 224 117 43 384 Credit-related contracts — 112 1 113 Other contracts 7 9 17 33 Long-term debt (4) — 1,990 713 2,703 Total liabilities measured at fair value on a recurring basis 2,433 10,369 779 13,581 September 30, 2021 Level 1 Level 2 Level 3 Assets/ Liabilities measured at fair value (in billions of yen) Assets: Trading securities (1) Japanese government bonds 2,612 9 — 2,621 Japanese local government bonds — 74 — 74 U.S. Treasury bonds and federal agency securities 4,900 770 — 5,670 Other foreign government bonds 760 527 — 1,287 Agency mortgage-backed securities — 4,715 — 4,715 Residential mortgage-backed securities — — 8 8 Certificates of deposit and commercial paper — 1,121 — 1,121 Corporate bonds and other (2) 58 1,780 826 2,664 Equity securities 1,961 227 30 2,218 Trading securities measured at net asset value (3) 374 Derivative financial instruments: Interest rate contracts 31 3,363 10 3,404 Foreign exchange contracts — 2,464 23 2,487 Equity-related contracts 189 283 23 495 Credit-related contracts — 113 3 116 Other contracts 26 4 33 63 Available-for-sale Japanese government bonds 18,807 196 — 19,003 Japanese local government bonds — 495 — 495 U.S. Treasury bonds and federal agency securities 1,074 — — 1,074 Other foreign government bonds 444 887 — 1,331 Agency mortgage-backed securities — 599 — 599 Residential mortgage-backed securities — 44 20 64 Commercial mortgage-backed securities — 1 766 767 Japanese corporate bonds and other debt securities — 1,637 347 1,984 Foreign corporate bonds and other debt securities — 764 117 881 Equity securities: Equity securities with readily determinable fair values 3,717 106 — 3,823 Equity securities measured at net asset value (3) 160 Other investments 3 — 53 56 Total assets measured at fair value on a recurring basis 34,582 20,179 2,259 57,554 Liabilities: Trading securities sold, not yet purchased 2,172 805 — 2,977 Derivative financial instruments: Interest rate contracts 30 3,210 5 3,245 Foreign exchange contracts — 2,382 1 2,383 Equity-related contracts 167 99 62 328 Credit-related contracts — 134 2 136 Other contracts 18 15 32 65 Long-term debt (4) — 2,111 752 2,863 Total liabilities measured at fair value on a recurring basis 2,387 8,756 854 11,997 Notes: (1) Trading securities include foreign currency denominated securities for which the MHFG Group elected the fair value option.

(5) Gains (losses) in Earnings are reported in Other noninterest income (expenses). (6) Amounts represent total gains or losses recognized in earnings and OCI during the period. These gains or losses were attributable to the change in fair value relating to assets and liabilities classified as Level 3 that were still held at September 30, 2020 and 2021. The amounts of unrealized gains (losses) in OCI are related to Available-for-sale securities and Long-term debt, which were ¥7 billion and ¥(8) billion, respectively, at September 30, 2020, and ¥nil billion and billion, respectively, at September 30, 2021. Transfers During the six months ended September 30, 2020, the transfers into Level 3 included ¥1 billion of net Derivative assets and ¥19 billion of Long-term debt. Transfers into Level 3 for net Derivative assets were primarily due to changes in the observability of the inputs used to measure fair value of certain credit-related derivatives. Transfers into Level 3 for Long-term debt were primarily due to changes in the observability of the default rate when valuing certain structured notes. During the six months ended September 30, 2020, the transfers out of Level 3 included ¥1 billion of Trading securities, ¥1 billion of net Derivative liabilities and ¥35 billion of Long-term debt. Transfers out of Level 3 for Trading securities were primarily due to increased price transparency for certain Japanese corporate bonds. Transfers out of Level 3 for net Derivative liabilities were primarily due to changes in the observability of the inputs used to measure fair value of certain credit-related derivatives. Transfers out of Level 3 for Long-term debt were primarily due to changes in the observability of the default rate when valuing certain structured notes. During the six months ended September 30, 2021, the transfers into Level 3 included ¥1 billion of net Derivative liabilities and ¥1 billion of Long-term debt. Transfers into Level 3 for net Derivative liabilities were primarily due to changes in the observability of the inputs used to measure fair value of certain credit-related derivatives. Transfers into Level 3 for Long-term debt were primarily due to changes in the observability of the default rate when valuing certain structured notes. During the six months ended September 30, 2021, the transfers out of Level 3 included ¥1 billion of Trading securities and ¥1 billion of Long-term debt. Transfers out of Level 3 for Trading securities were primarily due to increased price transparency for certain foreign bonds. Transfers out of Level 3 for Long-term debt were primarily due to changes in the observability of the default rate when valuing certain structured notes .

(2) This input is mainly used for determining the fair values of Japanese corporate bonds and foreign corporate bonds. (3) Internal valuation model includes discounted cash flow models and the Black-Scholes option pricing model. (4) This input represents the counterparty default rate derived from the MHFG Group’s own internal credit analyses. (5) Averages are calculated by weighting each input by the relative fair value of the respective financial instruments except for derivative related inputs where medians are used. IR = Interest rate FX = Foreign exchange Uncertainty of fair value measurements relating to unobservable inputs and interrelationships among unobservable inputs The following is a description of the uncertainty of the fair value measurements from the use of significant unobservable inputs and a description of interrelationships of the significant unobservable inputs used to measure the fair values of Level 3 assets and liabilities. (1) Prepayment rate The prepayment rate is the estimated rate at which voluntary unscheduled repayments of the principal of the underlying assets are expected to occur. The movement of the prepayment rate is generally negatively correlated with borrower delinquency. A change in prepayment rate would impact the valuation of the fair values of financial instruments either positively or negatively, depending on the structure of financial instruments. (2) Default rate The default rate is an estimate of the likelihood of not collecting contractual payments. An increase in the default rate would generally be accompanied by a decrease in the recovery rate and an increase in the discount margin. It would also generally impact the valuation of the fair values of financial instruments negatively. (3) Recovery rate The recovery rate is an estimate of the percentage of contractual payments that would be collected in the event of a default. An increase in recovery rate would generally be accompanied by a decrease in the default rate. It would also generally impact the valuation of the fair values of financial instruments positively. (4) Discount margin The discount margin is the portion of the interest rate over a benchmark market interest rate such as Tokyo Interbank Offered Rate (“TIBOR”) or swap rates. It primarily consists of a risk premium component which is the amount of compensation that market participants require due to the uncertainty inherent in the financial instruments’ cash flows resulting from credit risk. An increase in discount margin would generally impact the valuation of the fair values of financial instruments negatively. (5) Correlation Correlation is the likelihood of the movement of one input relative to another based on an established relationship. The change in correlation would impact the valuation of derivatives either positively or negatively, depending on the nature of the underlying assets. (6) Volatility Volatility is a measure of the expected change in variables over a fixed period of time. Some financial instruments benefit from an increase in volatility and others benefit from a decrease in volatility. Generally, for a long position in an option, an increase in volatility would result in an increase in the fair values of financial instruments. Items measured at fair value on a nonrecurring basis Certain assets and liabilities are measured at fair value on a nonrecurring basis. These assets and liabilities primarily include items that are measured at the lower of cost or fair value, and items that were initially measured at cost and have been written down to fair value as a result of impairment. The following table shows the fair value hierarchy for these items as of March 31, 2021 and September 30, 2021: March 31, 2021 Total Level 1 Level 2 Level 3 Aggregate cost (in billions of yen) Assets: Loans 85 — 3 82 167 Loans held-for-sale 22 — 21 1 23 Equity securities (without readily determinable fair values) 3 — — 3 4 Premises and equipment-net — — — — 7 Other assets 24 — — 24 34 Total assets measured at fair value on a nonrecurring basis 134 — 24 110 235 September 30, 2021 Total Level 1 Level 2 Level 3 Aggregate cost (in billions of yen) Assets: Loans 57 — — 57 102 Loans held-for-sale 21 — 11 10 22 Equity securities (without readily determinable fair values) 24 — 16 8 10 Other investments 3 3 — — 5 Total assets measured at fair value on a nonrecurring basis 105 3 27 75 139 Note: The fair values may not be current as of the dates indicated, but rather as of the da t Loans in the table above became nonaccrual and are measured based upon the observable market price of the loan, which is classified as Level 2, or the fair value of the underlying collateral, which is classified as Level 3. Loans held-for-sale Equity securities (without readily determinable fair values) in the table above consist of non-marketable non-marketable non-marketable non-marketable Other investments in the table above include certain equity method investments which have been impaired and written down to fair value. The fair values of the impaired marketable equity method investments are determined by their quoted market prices. As the securities are traded on an active exchange market, they are classified as Level 1. There were no other investments measured at fair value on a nonrecurring basis as of March 31, 2021. Premises and equipment—net and Other assets in the table above have been impaired and written down to fair value. There were no premises and equipment—net and other assets measured at fair value on a nonrecurring basis as of September 30, 2021. Fair value option The MHFG Group elected the fair value option for certain eligible financial instruments described below. Foreign currency denominated debt securities The MHFG Group elected the fair value option for foreign currency denominated debt securities to mitigate the volatility in earnings due to the difference in the recognition of foreign exchange risk between foreign currency denominated debt securities and financial liabilities. Following the election of the fair value option, these debt securities are 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. Fair value option has only been elected for part of the portfolio as the Group would not achieve operational simplifications. In addition, the Group measures certain notes that contain embedded derivatives at fair value under the practicability exception. These notes continue to be reported in Long-term debt and interest on these notes continues to be reported in Interest expense on long-term debt based on the contractual rates. Only an immaterial amount included in Long-term debt in the statement of financial position is not eligible for fair value option. The differences between the aggregate fair value of these notes and the aggregate unpaid principal balance of such instruments were ¥14 billion and ¥11 billion at March 31, 2021 and September 30, 2021, respectively. The net unrealized gains (losses) resulting from changes in fair values of these notes recorded in Other noninterest income (expenses) were of ¥17 billion and ¥(30) billion for the six months ended September 30, 2020 and 2021, respectively. Changes in fair value resulting from changes in instrument-specific credit risk were estimated by incorporating the Company’s current credit spreads observable in the bond market. Fair value of financial instruments ASC 825, “Financial Instruments” (“ASC 825”), requires the disclosure of the estimated fair value of financial instruments. The 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. These estimates could be significantly affected by different sets of assumptions. There are certain limitations to management’s best judgment in estimating fair values of financial instruments and inherent subjectivity involved in 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. The following is a description of the valuation methodologies used for estimating the fair value of financial assets and liabilities not carried at fair value on the MHFG Group’s consolidated balance sheets. Cash and due from banks, interest-bearing deposits in other 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 |

Offsetting of financial assets and financial liabilities | 18. Offsetting of financial assets and financial liabilities Derivatives The MHFG Group enters into master netting arrangements such as International Swaps and Derivatives Association, Inc. (“ISDA”) or similar agreements with counterparties to manage mainly credit risks associated with counterparty default. If the predetermined events including counterparty default occur, these enforceable master netting arrangements or similar agreements give the Group the right to offset derivative receivables and derivative payables and related financial collateral such as cash and securities with the same counterparty. Repurchase and resale agreements and securities lending and borrowing transactions Repurchase and resale agreements and securities lending and borrowing transactions are generally covered by industry standard master repurchase agreements and industry standard master securities lending agreements with netting terms to manage mainly credit risks associated with counterparty default. In the event of default by the counterparty, these agreements with netting terms provide the Group with the right to offset receivables and payables related to such transactions with the same counterparty, and to liquidate the collateral held. The following table provides information about the offsetting of financial assets and financial liabilities at March 31, 2021 and September 30, 2021. The table includes derivatives, repurchase and resale agreements, and securities lending and borrowing transactions that are subject to enforceable master netting arrangements or similar agreements irrespective of whether or not they are offset on the Group’s consolidated balance sheets.

For securities lending transactions, the Group receives collateral in the form of cash. These contracts involve risks, including (1) the counterparty may fail to return the securities at maturity and (2) the fair value of the securities posted may decline below the amount of the Group’s obligation and therefore the counterparty may require additional amounts. The Group attempts to mitigate these risks by entering into transactions mainly with central counterparty clearing houses which revalue assets and perform margin maintenance activities on a regular basis, diversifying the maturities and counterparties, and using mainly highly liquid securities. The amounts or composition of assets pledged as collateral for borrowings and for other purposes have not changed significantly since March 31, 2021.

Basis of presentation | 1. Basis of presentation Mizuho Financial Group, Inc. (“MHFG”) is a joint stock corporation with limited liability under the laws of Japan. MHFG is a holding company for Mizuho Bank, Ltd. (“MHBK”), Mizuho Trust & Banking Co., Ltd. (“MHTB”), Mizuho Securities Co., Ltd. (“MHSC”), Asset Management One Co., Ltd. (“Asset Management One”), and other subsidiaries. MHFG, through its subsidiaries (“the MHFG Group,” or “the Group”), provides domestic and international financial services in Japan and other countries. For a discussion of the Group’s segment information, see Note 20 “Business segment information.” MHFG and its domestic subsidiaries as well as its foreign subsidiaries maintain their accounting records in accordance with the accounting standards of Japan and those standards of the countries in which they are domiciled. Certain adjustments and reclassifications have been incorporated in the accompanying consolidated financial statements to conform them to 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. MHFG’s interim financial reporting period ends on September 30. Certain of MHFG’s subsidiaries have different interim financial reporting periods than September 30. For those subsidiaries with interim financial reporting periods within three months of MHFG’s interim financial reporting period, the effect of intervening events that materially affect the financial position or results of operations through the date of each of the periods presented in the MHFG’s consolidated financial statements have been considered for adjustment and/or disclosure. When determining whether to consolidate investee entities, the MHFG Group performs an analysis of the facts and circumstances of the particular relationships between the MHFG Group and the investee entities as well as the ownership of voting shares. The consolidated financial statements also include the accounts of VIEs for which MHFG or its subsidiaries have been determined to be the primary beneficiary in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, “Consolidation” (“ASC 810”). All significant intercompany transactions and balances have been eliminated upon consolidation. The MHFG Group accounts for investments in entities over which it has significant influence by 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 Equity in earnings (losses) of equity method investees-net. On October 1, 2020, a 1-for-10 The unaudited interim consolidated financial statements should be read in conjunction with the audited financial statements and related notes included in the MHFG Group’s most recent annual report on Form 20-F for the fiscal year ended March 31, 2021. Certain financial information that is normally included in annual financial statements prepared in accordance with U.S. GAAP, but is not required for interim reporting purposes, has been condensed or omitted. The financial statements reflect all normal and recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods. |
Use of estimates | Use of estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make 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 the allowance for credit losses, valuation of deferred tax assets, valuation of derivative financial instruments, valuation of investments, valuation of certain long-term debt where the fair value option has been elected, valuation of pension and other employee benefits, and impairment of long-lived assets. During times of pandemics, such as COVID-19, |
Financial instruments—current expected credit losses ("CECL") | Financial instruments—current expected credit losses (“CECL”) The adoption of this guidance established a single allowance framework for all financial assets measured at amortized cost and certain off-balance-sheet losses available-for-sale further impact |
Allowance and provision (credit) for credit losses on loans | Allowance and provision (credit) for credit losses on loans Effective April 1, 2020, the allowance for credit losses on loans is established for current expected credit losses on the MHFG Group’s loan portfolio in accordance with ASC 326. Additionally, as of April 1, 2020, the Group did not elect the fair value option for financial assets measured at amortized cost basis. Prior to April 1, 2020, the allowance for credit losses on loans was established The MHFG Group makes adjustments to the allowance for credit losses on loans through Provision (credit) for credit losses in the consolidated statements of income in each reporting period. Loan principal that management judges to be uncollectible, based on detailed loan reviews and a credit quality assessment, is charged off against the allowance for credit losses on loans. In general, the Group charges off loans when the Group determines that the obligor should be classified as substantially bankrupt or bankrupt. See Note 4 “Loans” for the definitions of obligor categories. Obligors in the retail portfolio segment are generally determined when they are past due for more than six months, and as for obligors in the corporate portfolio segment, the Group separately monitors the credit quality of each obligor without using time-based triggers. The MHFG Group maintains an appropriate allowance for credit losses on loans to represent management’s estimate of the expected credit losses in the Group’s loan portfolio. Management evaluates the appropriateness of the allowance for credit losses on loans semi-annually. The allowance considers expected credit losses over the remaining expected lives of the applicable ratings When determining expected credit losses, a single forward-looking macroeconomic scenario is considered over a reasonable and supportable forecast period. This forward-looking macroeconomic scenario is consistent to what is used in the MHFG Group’s stress testing and is in line with the scenario used for the Group’s business plan. If the scenario does not reflect a sudden change in economic conditions adequately, adjustments may be made to the scenario. After the forecast period, the Group reverts to long-term historical loss experience with a certain graduated transition period, to estimate losses over the remaining lives of financial assets measured at amortized cost and certain off-balance-sheet In terms of the internal risk ratings, for the corporate portfolio segment, the credit quality review process and the credit rating process serve as the basis for determining the allowance for credit losses on loans. 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, analysis of relevant industry segments and current trends. For the retail portfolio segment, the different categories of past due status of loans are primarily utilized in the credit quality review and the credit rating processes as the basis for determining the allowance for credit losses on loans. In general, the MHFG Group estimates expected credit losses collectively on the loans in the case of normal and watch obligors, considering the risk associated with a particular pool and the probability that the exposures within the pool will deteriorate or default. The allowance for credit losses on nonaccrual loans includes the allowance for groups of loans which were collectively evaluated for expected credit losses, in addition to the allowance for those loans that were individually evaluated for expected credit losses. See Note 4 “Loans” for the definitions of obligor categories and classification of nonaccrual loans. The estimation of expected credit losses that are evaluated collectively begins with a quantitative calculation that considers the likelihood of the borrower changing delinquency status or moving from one obligor category or rating to another. The quantitative calculation covers expected credit losses over an instrument’s expected life and is estimated by applying credit loss factors to the MHFG Group’s estimated exposure at default. The credit loss factors incorporate the probability of default as well as the loss given default based on the historical loss rates. To supplement the historical loss data for overseas obligors, external credit ratings such as S&P are also used evaluated collectively are analyzed on a periodic basis by comparing the estimated values with the actual results subsequent to the balance sheet date. The MHFG Group divides its overall portfolio into domestic and foreign portfolios and categorizes the domestic portfolio into four portfolio segments according to their risk profiles: corporate, retail, sovereign, and banks and financial institutions. The corporate portfolio segment consists of loans originated primarily by MHBK and MHTB, and includes mainly business loans such as those used for working capital and capital expenditure, as well as loans for which the primary source of repayment of the obligation is income generated by the relevant assets such as project finance, asset finance and real estate finance. The corporate portfolio segment is divided into two classes based on their risk characteristics: large companies, and small and medium-sized The retail portfolio segment consists mainly of residential mortgage loans originated by MHBK, and it is divided into two classes based on their risk characteristics: housing loan and others. For the retail portfolio segment, the Japanese unemployment rate is applied as a key factor. As it pertains to troubled debt restructuring (“TDR”) loans in the retail portfolio segment, the restructuring itself, as well as subsequent payment defaults, if any, are considered in determining obligor categories. Expected credit loss estimates also include consideration of expected cash recoveries on loans previously charged-off, The allowance recorded for individually evaluated loans is based on (1) the present value of expected future cash flows, after considering the restructuring effect and subsequent payment default with respect to TDRs, discounted at the loan’s initial effective interest rate, (2) the loan’s observable market price, or (3) the fair value of the collateral if the loan is collateral dependent. The collateral that the MHFG Group obtains for loans consists primarily of real estate. In obtaining the collateral, the Group evaluates the fair value of the collateral and its legal enforceability. The Group also performs subsequent re-evaluations The MHFG Group’s methodology for determining the appropriate allowance for credit losses on loans also considers the imprecision inherent in the methodologies used. As a result, the amounts determined under the methodologies described above could be adjusted by management to consider the potential impact of other qualitative factors which include, but are not limited to, imprecision in macroeconomic scenario assumptions and emerging risks related to changes in the environment that are affecting specific portfolio segments. Considering internal and external factors affecting the credit quality of the portfolio, the Group incorporated the estimated impact of COVID-19 |
