• | Japan’s real gross domestic product on a quarterly basis, compared to the corresponding period of the previous year, increased by 1.5% in the third quarter of calendar year 2023. Japan’s real gross domestic product on a quarterly basis, compared to the corresponding period of the previous year, decreased consecutively from the fourth quarter of calendar year 2019 through the first quarter of calendar year 2021, and increased consecutively from the second quarter of calendar year 2021 through the third quarter of calendar year 2023. |
• | In September 2016, the Bank of Japan introduced “quantitative and qualitative monetary easing with yield curve control” by strengthening its two previous policy frameworks, namely “quantitative and qualitative monetary easing (“QQE”)” and “QQE with a negative interest rate.” These policies aimed to drive the observed consumer price index to a level exceeding the price stability target of 2% and to maintain the index above that target in a stable manner. Under the new policy framework, the BOJ set a guideline for market operations: regarding short-term interest rates, the BOJ will apply an interest rate of negative 0.1% to certain excess balances in current accounts held by financial institutions at the BOJ; and regarding long-term interest rates, it would purchase Japanese government bonds to control long-term interest rates so that the yield of 10-year Japanese government bonds will remain at around 0%. |
• | The yield on newly issued 10-year Japanese government bonds, which is a key long-term interest rate indicator, was 0.351% as of March 31, 2023 and increased to 0.765% as of September 29, 2023. Thereafter, the yield decreased to 0.672% as of November 30, 2023. |
• | The Nikkei Stock Average, which is an average of the price of 225 stocks listed on the Tokyo Stock Exchange, increased by 13.6% to ¥31,857.62 as of September 29, 2023 compared to March 31, 2023. Thereafter, the Nikkei Stock Average increased further to ¥33,486.89 as of November 30, 2023. |
• | The yen to U.S. dollar spot exchange rate, according to the BOJ, was ¥133.13 to $1.00 as of March 31, 2023 and weakened to ¥148.77 to $1.00 as of September 29, 2023. Thereafter, the yen strengthened to ¥147.06 to $1.00 as of November 30, 2023. |
• | According to Teikoku Databank, a Japanese research institution, in Japan, there were 3,123 corporate bankruptcies in the six months ended September 30, 2022, involving approximately ¥1.8 trillion in total liabilities, 3,676 corporate bankruptcies in the six months ended March 31, 2023, involving approximately ¥0.6 trillion in total liabilities, and 4,208 corporate bankruptcies in the six months ended September 30, 2023, involving approximately ¥1.6 trillion in total liabilities. The number of corporate bankruptcies in the six months ended September 30, 2023 was higher than the corresponding period of the previous year for two consecutive years and exceeded 4,000 corporate bankruptcies for the first time since 2020. |

For the six months ended September 30, 2022 and 2023, net gains (losses) related to ETFs and others amounted to ¥billion are included in GMC, respectively. |
(3) | “General and administrative expenses” excludes non-allocated gains (losses), net. |
(4) | Net business profits (losses) is used in Japan as a measure of the profitability of core banking operations, and is defined as gross profits (as defined above) less general and administrative expenses (excluding non-allocated gains (losses), net) plus equity in earnings (losses) of equity method investees-net less amortization of goodwill and others. Measurement of net business profits (losses) is required for regulatory reporting to the Financial Services Agency of Japan. |
(5) | “Fixed assets” is presented based on Japanese GAAP and corresponds to the total amount of the following U.S. GAAP accounts: Premises and equipment-net; Goodwill; Intangible assets; and right-of-use |
(6) | “Others” includes the following items: |
• | profits and expenses pertaining to consolidated subsidiaries that are not subject to allocation; |
• | consolidating adjustments, including elimination of internal transaction between each segment; |

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. Certain comparative amounts for the prior period have been reclassified in order to conform to the current period’s presentation. 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, 2023. 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 loans held-for-sale, Financial instruments—current expected credit losses (“CECL”) CECL established a single allowance framework for all financial assets measured at amortized cost and certain off-balance-sheet instrument exposures. This framework requires management’s estimate to reflect credit losses over the instrument’s remaining expected life and consider expected future changes in macroeconomic conditions. ASC 326, “Financial Instruments—Credit Losses” (“ASC 326”), replaced the incurred loss impairment methodology in prior U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of information such as relevant information about past events including historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amount, for the purpose of informing credit loss estimates. This ASC requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. This ASC also requires that credit losses on available-for-sale Allowance and provision (credit) for credit losses on loans 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 to be substantially bankrupt 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 instruments. The expected life of each instrument is determined by considering expected prepayments, contractual terms and cancellation features. The allowance for credit losses involves significant judgments on a number of matters including expectations of future economic conditions, assignment of obligor ratings, valuation of collateral, and the development of qualitative adjustments. 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 in line with the scenario used for the Group’s business plan. If the scenarios are not reflective of management’s expectation, 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 instruments. The macroeconomic scenario is updated semi-annually in principle and is reviewed to reflect current economic conditions and the Group’s expectation of future conditions on a timely basis. For March 31, 2023 and September 30, 2023, the Group used the most recent macroeconomic scenario available during the Group’s credit loss estimation process. 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 generally includes 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 to calculate the probability of default. The model and inputs used to determine credit losses on loans that are 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 companies. For the corporate portfolio segment, the MHFG Group considers key economic factors such as gross domestic products for Japan and each relevant foreign location, where the portfolio is significant, and the interest rates in Japan when estimating the credit loss. 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 modified 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, or expected recoveries on collateral dependent loans where recovery is expected through sale of the collateral. 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 modified loans, discounted at the loan’s post-modification contractual 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 at least once a year. As it pertains to real estate collateral, valuation is generally performed by an appraising subsidiary which is independent from the Group’s loan origination departments by using generally accepted valuation techniques such as (1) the replacement cost approach, (2) the sales comparison approach or (3) the income approach. In the case of large real estate collateral, the Group generally engages third-party appraisers to perform the valuation. 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 including segments impacted by the Russia-Ukraine situation, the deterioration of relations between the US and China adversely impacting the global economy and particularly certain business sectors, including the semiconductor industry, in addition to the recovery of inbound tourist demand following the end of COVID-19, and the inflation of import prices due to the depreciation of the yen. Considering internal and external factors affecting the credit quality of the portfolio, the Group incorporated the estimated impact of the Russia-Ukraine situation, current relations between the US and China, energy prices, financial variables including interest rates and exchange rates, increased labor costs, the downturn of the semiconductor market and its potential prolongation and other factors contributing to economic uncertainty into the macroeconomic scenario by using assumptions such as the future outlook of the business environment for specific portfolio segments and the current forecast for the growth rate of gross domestic product. In terms of the Russia-Ukraine situation, considering the country risk arising from the continued sanctions against Russia and the downgrading of their credit rating, the MHFG Group incorporated the estimated impact of the Russia-Ukraine situation into the macroeconomic scenario used for determining the allowance for credit losses on loans. Allowance and provision (credit) for credit losses on off-balance-sheet instruments The MHFG Group maintains an allowance for credit losses on off-balance-sheet instruments, such as guarantees and standby letters of credit in the same manner as the allowance for credit losses on loans. The Group similarly 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. Net changes in the allowance for credit losses on off-balance-sheet instruments are accounted for in Provision (credit) for credit losses on off-balance-sheet instruments in the consolidated statements of income. Allowance and provision (credit) for credit losses on available-for-sale The MHFG Group performs periodic reviews to identify impaired securities in accordance with ASC 326.

Issued accounting pronouncements | 2. Issued accounting pronouncements Adopted accounting pronouncements In March 2020, the FASB issued ASU No.2020-04, “Reference Rate Reform (Topic 848)—Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU No.2020-04”). The ASU provides optional expedients and exceptions for contracts, hedging relationships, and other transactions affected by reference rate reform. In January 2021, the FASB issued ASU No.2021-01, “Reference Rate Reform (Topic 848)—Scope” (“ASU No.2021-01”). The ASU clarifies that certain optional expedients and exceptions for contract modifications and hedge accounting apply to derivatives that are affected by the transition. In December 2022, the FASB issued ASU No.2022-06, “Reference Rate Reform (Topic 848)—Deferral of the Sunset Date of Topic 848” (“ASU No.2022-06”). The ASU amends the sunset date of Topic 848 from December 31, 2022 to December 31, 2024. ASU No.2020-04 is effective as of March 12, 2020 through December 31, 2024. ASU No.2021-01 is effective as of January 7, 2021 through December 31, 2024. ASU No.2022-06 is effective as of December 21, 2022 through December 31, 2024. The MHFG Group has elected the practical expedient for modifications of contracts. The practical expedient provides an election to account for certain contract amendments related to reference rate reform without the requirement to assess the significance of the modifications. The main reason for applying the practical expedient is to ease the administrative burden of accounting for contracts impacted by reference rate reform. This election has not had, and is expected to not have, a material impact on the Group’s consolidated results of operations or financial condition. In March 2022, the FASB issued ASU No.2022-02, “Financial Instruments—Credit Losses (Topic 326)—Troubled Debt Restructurings and Vintage Disclosures” (“ASU No.2022-02”). The amendments in this update eliminate the accounting guidance for troubled debt restructurings (“TDR”s) by creditors in Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. The amendments in this update also require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Topic 326. The MHFG Group adopted ASU No.2022-02 on April 1, 2023. The adoption of ASU No.2022-02 did not have a material impact on its consolidated results of operations or financial condition. The amendments related to disclosures are required to be applied prospectively beginning as of the date of adoption. See Note 4 “Loans” for new disclosures for periods beginning on and after April 1, 2023. |

Notes:
Contractual maturities The amortized cost, net of allowance for credit losses, and fair value of available-for-sale held-to-maturity
Credit losses The MHFG Group did not recognize allowance for credit losses on available-for-sale available-for-sale held-to-maturity held-to-maturity Continuous unrealized loss position The following table shows the gross unrealized losses, net of allowance for credit losses, and fair value of available-for-sale
Available-for-sale securities are considered impaired if the fair value is less than the amortized cost. The MHFG Group recognizes impairment losses in earnings if the Group has the intent to sell the debt security, or if it is more likely than not that the Group will be required to sell the debt security before recovery of its amortized cost. For Japanese government bonds, U.S. Treasury bonds and federal agency securities and Agency mortgage-backed securities, their entire amortized cost bases are 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 are 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. Realized gains and losses The following table shows the realized gains and losses on sales of available-for-sale
Equity securities Equity securities include securities which have readily determinable fair values, securities which qualify for the practical expedient to estimate fair value using the net asset value per share (or its equivalent), and securities which are without readily determinable fair values. Equity securities which have readily determinable fair values mainly consist of common stock of Japanese listed companies. Equity securities which are measured based on the net asset value per share (or its equivalent) consist of private equity and real estate funds. Equity securities without readily determinable fair values include non-marketable stock including preferred stock issued by equity method investees. Net gains and losses The following table shows the details of the net gains and losses on Equity securities for the six months ended September 30, 2022 and 2023:
Equity securities without readily determinable fair values The following table shows carrying amounts of equity securities without readily determinable fair values, for which the measurement alternative is used, and cumulative amounts due to downward adjustments and impairments and upward adjustments, at March 31, 2023 and September 30, 2023:
The following table shows amounts recognized in earnings during the period due to downward adjustments and impairments and upward adjustments for equity securities without readily determinable fair values.
The MHFG Group elected to measure all equity securities without readily determinable fair values, which do not qualify for the practical expedient to estimate fair value, using the measurement alternative, which is made on an instrument-by-instrument minus changes resulting from observable price changes in orderly transactions for the identical or similar securities of the same issuer. In addition, the Group assesses whether these equity securities are impaired. Impairment is primarily based on a liquidation value technique that considers the financial condition, credit ratings, and near-term prospects of the issuers. When the observable price changes or impairments exist, the securities are adjusted to fair value, with the full difference between the fair value of the security and its carrying amount recognized in earnings. Other investments The following table summarizes the composition of Other investments at March 31, 2023 and September 30, 2023:
Equity method investments Investments in investees over which the MHFG Group has the ability to exert significant influence are accounted for using the equity method of accounting. Such investments included marketable equity securities with carrying values of ¥268,736 million and ¥306,734 million, at March 31, 2023 and September 30, 2023, respectively. The aggregate market values of these marketable equity securities were ¥503,171 million and ¥601,763 million, respectively. non-marketable equity securities such as Matthews International Capital Management, LLC, Custody Bank of Japan, Ltd. and Rakuten Securities, Inc. of which the Group’s proportionate share of the total outstanding common stock were 18.27%, 27.00% and 20.00%, respectively. Investments held by consolidated investment companies The MHFG Group consolidates certain investment companies over which it has control through either ownership or other means. Investment companies are subject to specialized industry accounting which requires investments to be carried at fair value, with changes in fair value recorded in earnings. The Group maintains this specialized industry accounting for investments held by consolidated investment companies, which consist of marketable and
non-marketable investments. |

Loans | 4. Loans 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 receivables included in Accrued income was ¥198 billion and ¥252 billion at March 31, 2023 and September 30, 2023, respectively. The Group does not believe that its exposure to any particular geographic area and business sector results in a significant concentration of credit risk. The table below presents the MHFG Group’s definition of obligor ratings used by MHBK and MHTB, and equivalent obligor ratings are determined for the other subsidiaries:
Notes:
The table below presents credit quality information of loans based on the MHFG Group’s internal rating system at March 31, 2023 and September 30, 2023:
Notes:
The table below presents gross charge-offs recognized for the six months ended September 30, 2023 :
Note: The majority of total foreign consist of corporate. 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. Unearned income and deferred loan fees was ¥238 billion and ¥251 billion at March 31, 2023 and September 30, 2023, respectively. The 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, 2023, collateral relating to these loans was primarily comprised of real estate. There were no significant changes in the extent to which collateral secures these loans during this period and no significant concentration of collateral against any portfolio segment. 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 payments 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 modified loans to borrowers experiencing financial difficulty. 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 loan repayment terms for the periods presented other than those already designated as nonaccrual loans. The majority of nonaccrual loans have no contractual delinquency due to interest reductions and/or postponement of principal and interest. In case loans are designated as 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 loans and 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 modified loans to borrowers experiencing financial difficulty, in general, such loans are restored to accrual loans, and accrual status, when the borrower qualifies for an obligor rating of D or above. The table below presents nonaccrual loans information at March 31, 2023 and September 30, 2023:
Notes:
The remaining balance of nonaccrual loans that have been partially charged off, was ¥11,314 million and ¥10,111 million as of March 31, 2023 and September 30, 2023, respectively.

Regulatory matters | 9. Regulatory matters Regulatory capital requirements MHFG, MHBK, and MHTB are subject to regulatory capital requirements supervised 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. Failure to meet minimum capital requirements may initiate certain mandatory actions by regulators that, if undertaken, could have a direct material effect on the MHFG Group’s consolidated financial condition and results of operations. Capital adequacy ratios and leverage ratios of MHFG, MHBK, and MHTB as of March 31, 2023 and September 30, 2023 calculated in accordance with Japanese GAAP and the guidelines established by the Financial Services Agency are set forth in the following table:
Notes:
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.

Income taxes | 11. Income taxes The following table presents the components of Income tax expense (benefit) for the six months ended September 30, 2022 and 2023:
The preceding table does not reflect the tax effects of items recorded directly in Equity for the six months ended September 30, 2022 and 2023. The detailed amounts recorded directly in Equity are as follows:
The statutory tax rates were both 30.62% as of September 30, 2022 and 2023. The effective tax rates, 30.55% and 30.18% for the six months ended September 30, 2022 and 2023, respectively, differed from the statutory tax rates. The differences between the tax rates for the six months ended September 30, 2022 and 2023 were immaterial. At September 30, 2023, the MHFG Group had net operating loss carryforwards totaling ¥446 billion. The total amount of unrecognized tax benefits was ¥ 9,224 million at September 30, 2023, 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. An immaterial portion of unrecognized tax benefits at March 31, 2023 was resolved in the six months period ended September 30, 2023. The amount of additional unrecognized tax benefits for the period 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. |

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 outstanding as of March 31, 2023 and September 30, 2023. The fair values of derivatives are presented on a gross basis; derivative receivables and payables are not offset. In addition, they are not offset against the amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral under master netting agreements in the consolidated balance sheets, or the table below.
Notes:
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 ¥989 billion and ¥1,008 billion at March 31, 2023, and ¥1,486 billion and ¥1,615 billion at September 30, 2023, 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 subsidiaries from foreign currency exposure. Under net investment hedges, both derivatives and nonderivative financial instruments qualify as hedging instruments. The foreign currency-denominated debt instruments qualifying as hedging instruments include deposits and long-term debt, of which the carrying amounts of the portion designated as net investment hedges are included within the respective items in the consolidated balance sheets as well as relevant accompanying notes. For net investment hedges, the entire change in the fair value of a hedging derivative instrument or nonderivative hedging financial instrument is recorded in Foreign currency translation adjustments within Accumulated other comprehensive income (loss), provided that the hedging instrument is designated as a hedge of the net investment. The gains and losses recorded in other comprehensive income (loss) related to net investment hedges were immaterial. 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, etc., (2) currency swap transactions for the purpose of economically managing the foreign exchange risk of these assets, (3) equity-related derivatives for the purpose of economically managing the risk of stock price fluctuation involved in holding equity products, and (4) credit derivatives for the purpose of economically managing the credit risk in loans, residential mortgage-backed securities (“RMBS”), commercial mortgage-backed securities (“CMBS”), collateralized loan obligations (“CLO”) and other similar assets. Such derivatives are accounted for as trading positions. The changes in fair value of these instruments are primarily recorded in Trading account gains (losses)—net, even though they are used to mitigate or transform the risk of exposures arising from banking activities. The net gains (losses) resulting from changes in the fair value of certain credit derivatives where the Group purchases protection to mitigate its credit risk exposure, related to its corporate loan portfolio, is recorded in Other noninterest income (expenses). The following table summarizes gains and losses on derivatives not designated or qualifying as hedges during the six months ended September 30, 2022 and 2023:
C redit 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, 2023 and September 30, 2023:
The following table shows the maximum potential amount of future payments for credit protection written by expiration period at March 31, 2023 and September 30, 2023:
Credit-related contingent features Certain of the MHFG Group’s derivative instruments contain provisions that require the Group’s debt to maintain an investment grade credit rating from the major credit rating agencies. 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. The following table shows the quantitative information about derivative instruments with credit-risk-related contingent features at March 31, 2023 and September 30, 2023:

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, 2023 and September 30, 2023. The maximum potential amount of future payments disclosed below represents the contractual amounts that could be required to be repaid in the event of the guarantees being executed, without consideration of possible recoveries under recourse provisions or from collateral held. With respect to written options included in derivative financial instruments in the table below, in theory, the MHFG Group is exposed to unlimited losses; therefore, the table shows the notional amounts of the contracts as a substitute for the maximum exposure.
The table below presents the maximum potential amount of future payments of performance guarantees, guarantees on loans, guarantees on securities and other guarantees classified based on internal ratings at March 31, 2023 and September 30, 2023:
Other off-balance-sheet instruments In addition to guarantees, the MHFG Group issues other off-balance-sheet instruments to its customers, such as lending-related commitments and commercial letters of credit. Under the terms of these arrangements, the MHFG Group is required to extend credit or make certain payments upon the customers’ requests.The table below summarizes the contractual amounts with regard to these undrawn commitments at March 31, 2023 and September 30, 2023:
Legal proceedings and investigations The MHFG Group is involved in normal collection proceedings initiated by the Group, other legal proceedings and investigations in the ordinary course of business. In accordance with ASC 450, “Contingencies” (“ASC 450”), the Group recognizes a liability for loss contingencies arising from such proceedings and investigations when a loss is probable and the loss amount or the range of the loss can be reasonably estimated. However, if a loss is reasonably possible but the range of loss is not probable and reasonably estimable, the Group does not recognize a liability but discloses the detail of such proceedings and investigations. Based on the information available as of the date of the consolidated financial statements, the Group believes that the outcome of the collection, legal proceedings and investigations will not have a significant adverse effect on the consolidated financial statements. |

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 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 assets and off-balance-sheet liabilities related to the VIEs. Further, this maximum potential loss is disclosed regardless of the probability of such losses and, therefore, it is not indicative of the ongoing exposure which is managed within the Group’s risk management framework. The table below shows the consolidated assets of the MHFG 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, 2023 and September 30, 2023:
As of March 31, 2023 and September 30, 2023, the noncontrolling interests in consolidated VIEs amounted to ¥719 billion and ¥802 billion, respectively, and are included in the MHFG Group’s equity-classified noncontrolling interests. The MHFG 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, 2023 and September 30, 2023:
In the table above the nature of the MHFG 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 MHFG 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 and/or cost-effective financing. The VIEs used in the programs purchase financial assets, primarily receivables, from clients participating in the programs and provide liquidity through the issuance of commercial paper or borrowings from the Group backed by the financial assets. While customers normally continue to service the transferred receivables, the Group underwrites, distributes, and makes a market in commercial paper issued by the conduits. The Group typically provides program-wide liquidity and credit support facilities and, in some instances, financing to the VIEs. The 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 financing. In substantially all of these structured financing transactions, the transfer of the financial asset by the client is structured to be bankruptcy remote by use of a bankruptcy remote entity, which is deemed to be a VIE because its equity holder does not have decision making rights. The Group receives fees for structuring and/or distributing the securities sold to investors. In some cases, the Group itself purchases the securities issued by the entities and/or provides loans to the VIEs. In addition, the MHFG Group establishes several single-issue and multi-issue special purpose entities that issue collateralized debt obligations (“CDO”) or CLO, synthetic CDO/CLO or other repackaged instruments to meet clients’ and investors’ financial needs. The Group also arranges securitization transactions including CMBS, RMBS and others. In these transactions, the 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 considers that these variable interests are not significant as the Group does not have material balance sheet or off-balance exposure at risk related to these variable interests. However, when the Group has invested in securities issued by the VIEs and/or provides loans to the VIEs and its investment is most part of shares, such variable interests are deemed to be “significant.” In certain VIEs, where the Group provides liquidity and credit support facilities, writes credit protection or invests in debt or equity instruments in its role as an arranger, servicer, administrator or asset manager, etc., the Group has the power to determine which assets will be held by the VIEs or to manage and monitor these assets. In addition, through the variable interests above, the Group has the obligation to absorb losses and the right to receive benefits that could potentially be significant to the VIEs. Therefore, the Group consolidates such VIEs. The MHFG Group manages Tender Option Bond (“TOB”) programs which are associated with trusts that hold highly-rated, fixed-rate and tax-exempt municipal bonds. The trust finances the purchase of their municipal bonds by issuing two types of certificates: (1) short-term puttable and floating-rate certificates (“floaters”), typically purchased by money market funds and (2) certificates that earn all excess cash flow received by the trust after floaters and fees are paid (“residuals”), purchased by the transferor of the municipal bond to the trust as a sponsor. The Group is engaged in two types of TOB trusts: customer TOB trusts and non-customer TOB trusts. Customer TOB trusts are those for which the residuals are purchased by customers of the Group, whereas the residuals issued by non-customer TOB trusts are purchased by the Group. Both types of TOB trusts are deemed to be VIEs because its equity holder does not have decision making rights. The 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 TOB trusts, where the Group holds the residuals as a sponsor, the Group has the power to determine which assets will be held by the VIEs or to manage and monitor these assets. In addition, through the variable interests above, the Group has the obligation to absorb losses and the right to receive benefits that could potentially be significant to the VIEs. Therefore, the Group consolidates such VIEs. Customer TOB trusts are not consolidated in the financial statements of the Group, as the residuals are held by customers and the Group does not have power to determine which assets will be held by the VIEs or to manage and monitor these assets. Investments in securitization products The MHFG Group invests in, among other things, various types of CDO/CLO, synthetic CDO/CLO and repackaged instruments, CMBS and RMBS arranged by third parties for the purpose of generating current income or capital appreciation, which all utilize entities that are deemed to be VIEs. By design, such investments were investment grade at issuance and held by a diverse group of investors. The potential loss amounts of the securities and the loans are generally limited to the amounts invested because the Group has no contractual involvement in such VIEs beyond its investments. Since the Group is involved in these VIEs only as an investor, the Group does not ordinarily have the power to direct the VIEs’ activities that most significantly impact the VIEs’ economic performance. Similar to the criteria noted in the asset-backed securitization section, the Group views this investment activity to be “significant” when it has a large investment share and/or provides loans to the VIEs. The Group consolidates VIEs, where the transactions are tailored by the third-party arrangers to meet the Group’s needs as a main investor, who is ultimately deemed to have the power to determine which assets are to be held by the VIEs. The Group also invests in certain beneficial interests issued by VIEs which hold real estate that the Group utilizes. In addition to these variable interests, when the Group has the power including the sole unilateral ability to liquidate the VIEs, the Group consolidates such VIEs. 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 MHFG 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 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 Group assumes certain risks by providing guarantees for the repayment of principal as required by the trust agreements or relevant Japanese legislation. The Group manages entrusted funds primarily through the origination of high-quality loans and other credit-related products, investing in investment grade marketable securities such as Japanese government bonds and placing cash with the Group’s subsidiary trust banks. The Group has the power to determine which assets will be held by the VIEs or to manage these assets. In addition, through the principal guarantee agreements, the Group has the obligation to absorb losses that could potentially be significant to the VIEs. Therefore, the Group consolidates such VIEs. However, the Group does not consolidate certain guaranteed principal money trusts, which invest all the entrusted funds in the Group itself, as the Group has determined that it has no variable interests. See Note 14 “Commitments and contingencies” for the balances of guaranteed trust principal that are not consolidated at March 31, 2023 and September 30, 2023. With respect to non-guaranteed trust arrangements, the MHFG Group manages and administers assets on behalf of its customers (trust beneficiaries) in the capacity of a trustee and fiduciary. For substantially all non-guaranteed trust arrangements, the Group generally does not have the power to direct the activities of the VIEs that most significantly impact the VIEs’ economic performance or has neither the obligation to absorb losses nor the right to receive benefits that could potentially be significant to the VIEs. Therefore, such trust accounts are not included in the consolidated financial statements of the Group. The MHFG Group established a trust in August 2020, which holds the Group’s housing loans and in turn issues beneficiary interests to the Group. The Group pledges the beneficiary interests as a collateral for borrowing from the Bank of Japan. In its role as a servicer, the Group has power to direct the entity’s activities that most significantly impact the entity’s economic performance by managing mortgage loans owned by a trust. The Group considers that it is a “significant” variable interest since the Group can determine which assets will be held by the VIE. In addition, through the beneficiary interest, the Group has the obligation to absorb losses and the right to receive benefits that could potentially be significant to the VIE. Therefore, the Group consolidates the VIE. 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 established a wholly-owned off-shore vehicle which issued subordinated bonds that are fully guaranteed by the Group, to investors unrelated to the Group to fund purchases of subordinated bonds issued by the Group. The entity is considered VIE because it lacks sufficient equity to finance its activities; however, the Group’s investment in the vehicle’s equity is not a variable interest because the investment is not considered to be at risk as the entire amount raised by the vehicle was used to purchase subordinated bonds issued by the Group. Because the Group does not have variable interests in the vehicle, the Group does not consolidate the entity. Subordinated bonds issued by the Group, which are included in Long-term debt, were ¥ 200 billion and ¥ 224 billion at March 31, 2023 and September 30, 2023, 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, 2022 and 2023, 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, 2023 and September 30, 2023. |

Noninterest income | 16. Noninterest income Details of Noninterest income for the six months ended September 30, 2022 and 2023 are as follows:
Notes:
Certain Fee and commission income, Trading account gains (losses)-net and Other noninterest income outlined in the table above are considered to be revenues from contracts that are within the scope of ASC 606. The MHFG Group disaggregates Fee and commission income, which is the main part of revenues within the scope of ASC 606, by type of business or service in the table above. Fee and commission income For the MHFG Group’s accounting policy for the recognition of Fee and commission income, see Note 1 “Basis of presentation and summary of significant accounting policies” to the consolidated financial statements in the Group’s most recent Form 20-F. Trust-related business fees consist of trust fees earned primarily through fiduciary asset management and administrative service and other trust-related fees, which amounted to ¥27 billion and ¥30 billion for the six months ended September 30, 2022, respectively, and ¥28 billion and ¥34 billion for the six months ended September 30, 2023, respectively. Trading account gains (losses)-net and Other noninterest income In addition to Fee and commission income, Trading account gains (losses)-net and Other noninterest income include certain revenues within the scope of ASC 606. Underwriting fees from trading securities, which amounted to ¥24 billion and ¥40 billion for the six months ended September 30, 2022 and 2023, respectively, are within the scope of ASC 606 and accounted for in Trading account gains (losses)-net. Underwriting fees are primarily recognized on the date which all the considerations of the transaction are fixed. For the six months ended September 30, 2022 and 2023, approximately ¥9 billion and ¥12 billion, respectively, of Other noninterest income were within the scope of ASC 606. Credit card interchange fees are within the scope of ASC 606 and accounted for in Other noninterest income. Credit card interchange fees are earned on credit card transactions conducted through payment networks and recognized upon settlement of the credit card payment transactions. Contract balances relating to revenues from contracts with customers subject to ASC 606 Contract assets and receivables from contracts with customers subject to ASC 606 are recognized in Accrued income or accounts receivable of Other assets. As of March 31, 2023 and September 30, 2023, the balance of contract assets was not material. Contract liabilities are recognized in unearned income of Other liabilities. As of March 31, 2023 and September 30, 2023, the balance of contract liabilities was not material. Remaining performance obligations relating to revenues from contracts with customers subject to ASC 606 Remaining performance obligations are services that the MHFG Group has committed to provide in the future in connection with its contracts with customers.

Fair value | 17. Fair value Fair value measurements ASC 820, “Fair Value Measurement ” (“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 :
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 assess 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 applied 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, 2023, 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. Though most securitization products are classified in Level 2, if the significant 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 investment approach across various asset classes globally. Hedge funds are measured at the net asset value (“NAV”) per share and the Group has the ability to redeem its investment with the investees at the NAV per share at the measurement date or within the near term. Private equity funds have specific investment objectives in connection with their acquisition of equity interests in new and emerging firms in need of capital. Employing venture capital strategies, they provide financing and other support to start-up businesses, medium and small entities in particular geographical areas, and to companies with certain technologies or companies in high-growth industries. Real estate funds invest globally and primarily in real estate companies, debt recapitalizations and direct property. Private equity funds and real estate funds are measured using the NAV per share practical expedient and the Group does not have the ability to redeem its investment in the investees at the NAV per share at the measurement date or within the near term. It is estimated that the underlying assets of the funds would be liquidated within a ten-year period. 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 Group calculates these credit-risk valuation adjustments using modeled expected exposure, and default probabilities and 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 quoted prices from broker-dealers. Such quotes are validated through the Group’s internal processes and controls. In rare instances where the Group finds the quoted prices to be invalid through its internal valuation process, it adjusts those prices or alternatively estimates their fair values by using a discounted cash flow model to incorporate the Group’s estimates of key inputs such as the most recent value of each underlying asset, cash flows of the underlying assets, and discount margin. The validation of such prices varies depending on the nature and type of the products. For the majority of RMBS and ABS, broker quotes are validated by investigating significant unusual monthly valuation fluctuations and comparing to prices internally computed through discounted cash flow models using assumptions and parameters provided by brokers such as the cash flows of underlying assets, yield curve, prepayment speed and credit spread. For the majority of CMBS, the Group validates broker quotes through a review process that includes the investigation of significant unusual monthly valuation fluctuations and/or a review of underlying assets with significant differences between the valuations of the Group and the broker-dealers being identified. Though most securitization products are classified in Level 2, if the significant inputs are unobservable or cannot be corroborated by observable market data, these financial instruments are classified in Level 3. 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 equity securities and debt securities. The fair value of the marketable equity securities is based upon quoted market prices. The fair value of the non-marketable equity securities is based upon significant management judgment, as very limited quoted prices exist. When evaluating 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 equity securities are generally classified in Level 3 of the fair value hierarchy. The fair value of the debt securities is estimated using a discounted cash flow model, since they have no quoted market prices. Those debt securities are classified in Level 3, because the credit risk is unobservable. Long-term debt and Other short-term borrowings Fair value accounting is elected for certain 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, 2023 and September 30, 2023, including those for which the MHFG Group has elected the fair value option, are summarized below:
Notes:
Items measured at fair value on a recurring basis using significant unobservable inputs (Level 3) The following table presents a reconciliation for all assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the six months ended September 30, 2022 and 2023:
Notes:
Transfers between levels During the six months ended September 30, 2022, the transfers into Level 3 included ¥8 billion of Trading securities and ¥1 billion of Long-term debt. Transfers into Level 3 for Trading securities were primarily due to decreased liquidity for certain foreign bonds. 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, 2022, the transfers out of Level 3 included ¥1 billion of Trading securities and ¥9 billion of Available-for-sale transparency for certain foreign bonds. securities . During the six months e nded September 30, 2023, the transfers into Leve l 3 included 1 billion of Long-term debt. Transfers into Level 3 for Long-term debt were primarily due to changes in the observability of the default rate when valuing certain structured loans. During the six months ended September 30, 2023, the transfers out of Level 3 included 4 billion of Trading securities, billion of Available-for-sale securities and 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 Available-for-sale securities were primarily due to increased price transparency for certain Foreign corporate bonds and other debt securities. Transfers out of Level 3 for Long-term debt were primarily due to changes in the observability of the defau lt rate when valuing certain structured notes.Quantitative information about Level 3 fair value measurements The following table presents information about significant unobservable inputs related to the MHFG Group’s material classes of Level 3 assets and liabilities at March 31, 2023 and September 30, 2023:
Notes:
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, 2023 and September 30, 2023:
Loans in the table above are classified as nonaccrual and are measured based upon the observable market price of the loan, which are classified as Level 2, or the fair value of the underlying collateral, which are classified as Level 3. Loans held-for-sale held-for-sale Equity securities (without readily determinable fair values) in the table above consist of non-marketable equity securities which are measured at fair value on a nonrecurring basis, using the measurement alternative for non-marketable equity securities. These equity securities are on a nonrecurring basis either (1) written down to fair value as a result of impairment or (2) adjusted upward or downward to fair value as a result of transactions observed for the identical or similar securities of the same issuer. The fair values of the impaired non-marketable equity securities are determined primarily by using a liquidation value technique. As significant management judgment or estimation is required in the determination of the fair values of non-marketable equity securities, they are classified as Level 3. The fair values of non-marketable equity securities adjusted based on observed transaction prices are mainly classified as Level 2. 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. The fair values of the impaired non-marketable equity method investments are determined primarily by using a liquidation value technique. As significant management judgment or estimation is required in the determination of the fair values of non-marketable equity method investments, they are classified as Level 3. There were no other investments measured at fair value on a nonrecurring basis as of September 30, 2023. Premises and equipment—net and Other assets in the table above have been impaired and written down to fair value. There were no other assets measured at fair value on a nonrecurring basis as of March 31, 2023 and no premises and equipment—net measured at fair value on a nonrecurring basis as of September 30, 2023. 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 Other short-term borrowings and Long-term debt. The interest on these notes continues to be reported in Interest expense on other short-term borrowings and long-term debt based on the contractual rates. Only an immaterial amount included in Other short-term borrowings and 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 ¥161 billion and ¥146 billion at March 31, 2023 and September 30, 2023, respectively. The net unrealized gains (losses) resulting from changes in fair values of these notes recorded in Other noninterest income (expenses) were of ¥128 billion and ¥34 billion for the six months ended September 30, 2022 and 2023, 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, interest-bearing deposits in other banks, call loans and funds sold, and receivables under resale agreements and securities borrowing transactions approximates the fair value of these assets since they generally involve limited losses from credit risk or have short-term maturities with interest rates that approximate market rates. Investments The fair value of held-to-maturity available-for-sale non-marketable equity securities is not readily determinable, nor practicable to estimate, due to the lack of available information. Their carrying amounts of ¥208 billion and ¥351 billion at March 31, 2023 and September 30, 2023, respectively, were not included in the disclosure. Loans Loans have been fair valued based on the type of loan, credit quality, prepayment assumptions and remaining maturity. The fair value of loans is determined based on discounted cash flows using interest rates approximating the MHFG Group’s current rates for similar loans. The fair value of collateral dependent nonaccrual loans is determined based on the fair value of the underlying collateral. Other financial assets The carrying value of other financial assets, which primarily consist of accounts receivable from brokers, dealers, and customers for securities transactions, accrued income and collateral provided for derivative transactions, approximates the fair value of these assets since they generally involve limited losses from credit risk or have short-term maturities with interest rates that approximate market rates. The majority of other financial assets is classified as Level 2, and included in the table in Note 6 “Other assets and liabilities.” Noninterest-bearing deposits, call money and funds purchased, and payables under repurchase agreements and securities lending transactions The carrying value of short-term financial liabilities, such as noninterest-bearing deposits, call money and funds purchased, and payables under repurchase agreements and securities lending transactions approximates the fair value of these liabilities since they generally have short-term maturities with interest rates that approximate market rates. Interest-bearing deposits The carrying value of demand deposits approximates the fair value since it represents the amount payable on demand at the balance sheet date. The fair value of time deposits and certificates of deposit is primarily estimated based on discounted cash flow analysis using current interest rates for instruments with similar maturities. The carrying value of short-term certificates of deposit approximates the fair value. Due to trust accounts The carrying value of due to trust accounts approximates the fair value since they generally have short-term maturities with interest rates that approximate market rates. Other short-term borrowings The carrying value of the majority of other short-term borrowings approximates the fair value since they generally have short-term maturities with interest rates that approximate market rates. The fair value of certain borrowings is estimated based on discounted cash flow analysis using interest rates approximating the MHFG Group’s incremental borrowing rates for instruments with similar maturities. Long-term debt Long-term debt is fair valued using quoted market prices, if available. Otherwise, the fair value of long-term debt is estimated based on discounted cash flow analysis using interest rates approximating the MHFG Group’s incremental borrowing rates for instruments with similar maturities. Other financial liabilities The carrying value of other financial liabilities, which primarily consist of accounts payable to brokers, dealers, and customers for securities transactions, accrued expenses and collateral accepted for derivative transactions, approximates the fair value since they generally have short-term maturities with interest rates that approximate market rates. The majority of other financial liabilities is classified as Level 2, and included in the table in Note 6 “Other assets and liabilities.” The fair value of certain off-balance-sheet financial instruments, such as commitments to extend credit and commercial letters of credit, was not considered material to the consolidated balance sheets at March 31, 2023 and September 30, 2023. The following table shows the carrying amounts and fair values at March 31, 2023 and September 30, 2023, of certain financial instruments, excluding financial instruments which are carried at fair value on a recurring basis and those outside the scope of ASC 825 such as equity method investments as defined in ASC 323, “Investments-Equity Method and Joint Ventures” (“ASC 323”) and lease contracts as defined in ASC 842, “Leases” (“ASC 842”):

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, 2023 and September 30, 2023. 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.

Repurchase agreements and securities lending transactions accounted for as secured borrowings | 19. Repurchase agreements and securities lending transactions accounted for as secured borrowings The following table shows the gross amounts of liabilities associated with repurchase agreements and securities lending transactions, by remaining contractual maturity at March 31, 2023 and September 30, 2023:
The following table shows the gross amounts of liabilities associated with repurchase agreements and securities lending transactions, by class of underlying collateral at March 31, 2023 and September 30, 2023:
The MHFG Group is required to post securities as collateral with a fair value equal to or in excess of the principal amount of the cash borrowed under repurchase agreements. 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, 2023. See Note 8 “Pledged assets and collateral” to the consolidated financial statements in the MHFG Group’s annual report on
Form 20-F for the year ended March 31, 2023 for additional information. |

Business segment information | 20. Business segment information The MHFG Group consists of the following five in-house companies which are categorized based on a customer segment: the Retail & Business Banking Company (“RBC”), the Corporate & Investment Banking Company (“CIBC”), the Global Corporate & Investment Banking Company (“GCIBC”), the Global Markets Company (“GMC”), and the Asset Management Company (“AMC”). These customer segments are regarded as operating segments and constitute reportable segments. The services that each in-house company is in charge of are as follows. RBC This company provides financial services for individual customers, small and medium-sized enterprises and middle market firms in Japan. CIBC This company provides financial services for large corporations, financial institutions and public corporations in Japan. GCIBC This company provides financial services for Japanese overseas affiliated corporate customers and non-Japanese corporate customers. GMC This company invests in financial products with market risk, such as interest rate risk, equity risk, and credit risk. AMC This company develops financial products and provides financial services that match the asset management needs of its wide range of customers from individuals to institutional investors. The reportable segment information, set forth below, is derived from the internal management reporting systems used by management to measure the performance of the Group’s operating segments. Management measures the performance of each of the operating segments in accordance with internal managerial accounting rules and practices. In addition, the format and information are presented primarily on the basis of Japanese GAAP. Therefore, they are not consistent with the consolidated financial statements prepared in accordance with U.S. GAAP. A reconciliation is provided for the total amount of all business segments’ “Net business profits (losses) + Net gains (losses) related to ETFs and others” with income before income tax expense under U.S. GAAP, and the total amount of all business segments’ “Fixed assets” with the total amount of Premises and equipment-net, Goodwill, Intangible assets, and right-of-use Effective as of April 1, 2023, MHFG partially restructured its in-house company system. CIBC was newly established by the integration of the Corporate & Institutional Company and the investment banking functions of the Global Products Unit. With the establishment of CIBC, the Global Corporate Company changed its name to GCIBC. Following such partial restructuring of our in-house company system and the associated changes in allocation method for transactions between each segment and “Others” (as such term is used in the tables, including the notes thereto) made in April 2023, reclassification was made regarding the figures for the six months ended September 30, 2022.
Notes:
Reconciliation As explained above, the measurement bases of the internal management reporting systems and the income and expenses items included are different from the accompanying consolidated statements of income. Therefore, it is impracticable to present reconciliations of all the business segment’s information, other than net business profits (losses), to the corresponding items in the accompanying consolidated statements of income. A reconciliation of “Net business profits (losses) + Net gains (losses) related to ETFs and others” for the six months ended September 30, 2022 and 2023 presented above to income (loss) before income tax expense (benefit) shown on the consolidated statements of income and a reconciliation of “Fixed assets” at September 30, 2022 and 2023 to the total amount of Premises and equipment-net, Goodwill, Intangible assets, and right-of-use

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. Certain comparative amounts for the prior period have been reclassified in order to conform to the current period’s presentation. 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, 2023. 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 loans held-for-sale, |
Financial instruments—current expected credit losses ("CECL") | Financial instruments—current expected credit losses (“CECL”) CECL established a single allowance framework for all financial assets measured at amortized cost and certain
off-balance-sheet instrument exposures. This framework requires management’s estimate to reflect credit losses over the instrument’s remaining expected life and consider expected future changes in macroeconomic conditions. ASC 326, “Financial Instruments—Credit Losses” (“ASC 326”), replaced the incurred loss impairment methodology in prior U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of information such as relevant information about past events including historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amount, for the purpose of informing credit loss estimates. This ASC requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. This ASC also requires that credit losses on available-for-sale |
Allowance and provision (credit) for credit losses on loans | Allowance and provision (credit) for credit losses on loans 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 to be substantially bankrupt 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 instruments. The expected life of each instrument is determined by considering expected prepayments, contractual terms and cancellation features. The allowance for credit losses involves significant judgments on a number of matters including expectations of future economic conditions, assignment of obligor ratings, valuation of collateral, and the development of qualitative adjustments. 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 in line with the scenario used for the Group’s business plan. If the scenarios are not reflective of management’s expectation, 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 instruments. The macroeconomic scenario is updated semi-annually in principle and is reviewed to reflect current economic conditions and the Group’s expectation of future conditions on a timely basis. For March 31, 2023 and September 30, 2023, the Group used the most recent macroeconomic scenario available during the Group’s credit loss estimation process. 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 generally includes 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 to calculate the probability of default. The model and inputs used to determine credit losses on loans that are 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 companies. For the corporate portfolio segment, the MHFG Group considers key economic factors such as gross domestic products for Japan and each relevant foreign location, where the portfolio is significant, and the interest rates in Japan when estimating the credit loss. 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 modified 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, or expected recoveries on collateral dependent loans where recovery is expected through sale of the collateral. 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 modified loans, discounted at the loan’s post-modification contractual 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 at least once a year. As it pertains to real estate collateral, valuation is generally performed by an appraising subsidiary which is independent from the Group’s loan origination departments by using generally accepted valuation techniques such as (1) the replacement cost approach, (2) the sales comparison approach or (3) the income approach. In the case of large real estate collateral, the Group generally engages third-party appraisers to perform the valuation. 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 including segments impacted by the Russia-Ukraine situation, the deterioration of relations between the US and China adversely impacting the global economy and particularly certain business sectors, including the semiconductor industry, in addition to the recovery of inbound tourist demand following the end of COVID-19, and the inflation of import prices due to the depreciation of the yen. Considering internal and external factors affecting the credit quality of the portfolio, the Group incorporated the estimated impact of the Russia-Ukraine situation, current relations between the US and China, energy prices, financial variables including interest rates and exchange rates, increased labor costs, the downturn of the semiconductor market and its potential prolongation and other factors contributing to economic uncertainty into the macroeconomic scenario by using assumptions such as the future outlook of the business environment for specific portfolio segments and the current forecast for the growth rate of gross domestic product. In terms of the Russia-Ukraine situation, considering the country risk arising from the continued sanctions against Russia and the downgrading of their credit rating, the MHFG Group incorporated the estimated impact of the Russia-Ukraine situation into the macroeconomic scenario used for determining the allowance for credit losses on loans. |
Allowance and provision (credit) for credit losses on off-balance-sheet instruments | Allowance and provision (credit) for credit losses on off-balance-sheet instruments The MHFG Group maintains an allowance for credit losses on off-balance-sheet instruments, such as guarantees and standby letters of credit in the same manner as the allowance for credit losses on loans. The Group similarly 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. Net changes in the allowance for credit losses on
off-balance-sheet instruments are accounted for in Provision (credit) for credit losses on off-balance-sheet instruments in the consolidated statements of income. |
Allowance and provision (credit) for credit losses on available-for-sale securities | Allowance and provision (credit) for credit losses on available-for-sale The MHFG Group performs periodic reviews to identify impaired securities in accordance with ASC 326.

Reportable Segment Information Derived from Internal Management Reporting Systems, on Basis of Japanese GAAP | The reportable segment information, set forth below, is derived from the internal management reporting systems used by management to measure the performance of the Group’s operating segments. Management measures the performance of each of the operating segments in accordance with internal managerial accounting rules and practices. In addition, the format and information are presented primarily on the basis of Japanese GAAP. Therefore, they are not consistent with the consolidated financial statements prepared in accordance with U.S. GAAP. A reconciliation is provided for the total amount of all business segments’ “Net business profits (losses) + Net gains (losses) related to ETFs and others” with income before income tax expense under U.S. GAAP, and the total amount of all business segments’ “Fixed assets” with the total amount of Premises and equipment-net, Goodwill, Intangible assets, and right-of-use Effective as of April 1, 2023, MHFG partially restructured its in-house company system. CIBC was newly established by the integration of the Corporate & Institutional Company and the investment banking functions of the Global Products Unit. With the establishment of CIBC, the Global Corporate Company changed its name to GCIBC. Following such partial restructuring of our in-house company system and the associated changes in allocation method for transactions between each segment and “Others” (as such term is used in the tables, including the notes thereto) made in April 2023, reclassification was made regarding the figures for the six months ended September 30, 2022.
