Notes to Quarterly Consolidated Financial Statements

Changes in Accounting Policies

(Accounting Standard for Revenue Recognition and Others)

MHFG has applied “Accounting Standard for Revenue Recognition” (ASBJ Statement No.29, March 31, 2020) and others from the beginning of the first quarter ended June 30, 2021.

In accordance with “Accounting Standard for Revenue Recognition”, MHFG recognizes revenue at the time of the transfer of promised goods or services to the customer in an amount that reflects the consideration to which MHFG expects to be entitled in exchange for those goods or services.

In accordance with transitional treatment set out in the proviso of Article 84 of “Accounting Standard for Revenue Recognition”, the cumulative effects arising from the retroactive application of these new accounting policies to all the previous fiscal years were reflected in Retained Earnings as of April 1, 2021, and the new accounting policies are applied from the beginning of the fiscal year.

As a result, Retained Earnings decreased by ¥724 million as of April 1, 2021. The impact on the quarterly consolidated statement of income for the nine months ended December 31, 2021 is immaterial.

In accordance with transitional treatment set out in the Article 28-15 of “Accounting Standard for Quarterly Financial Reporting and its Implementation Guidance” (ASBJ Statement No.12, March 31, 2020), the breakdown of revenue from contracts with customers for the nine months ended December 31, 2020 is not presented.

Additional Information

The Board Benefit Trust (“BBT”) Program

Since MHFG operates its business to contribute to the creation of value for diverse stakeholders and realize improved corporate value through the continuous and stable growth of MHFG group pursuant to MHFG’s basic management policy defined under the Mizuho Financial Group’s Corporate Identity, MHFG has introduced a stock compensation program using a trust (the “Program”) that functions as an incentive for each Director, Group Executive Officer, and Operating officers to exert maximum effort in performing his or her duties, and also as consideration for such exertion of effort.

(1) Outline of the Program

The Program has adopted the Board Benefit Trust (“BBT”) framework. MHFG’s shares on the stock market will be acquired through a trust established based on the underlying funds contributed by MHFG, and MHFG’s shares will be distributed to Directors, Executive Officers, and Operating officers of MHFG, Mizuho Bank, Ltd., Mizuho Trust & Banking Co., Ltd., and Mizuho Securities Co., Ltd. (the “Company Group”) and other entities in accordance with the Rules on Distribution of Shares to be prescribed in advance. The framework consists of the stock compensation program based on the Company Group Officer’s responsibilities and others in their respective company (“Stock Compensation I”), the stock compensation program based on the performance evaluation of the Company Group (“Stock Compensation II”) and the stock compensation program based on Company Group Officer’s responsibilities in their respective company and the performance evaluation of the Company Group, which distributes MHFG’s shares to Operating officers of MHFG and certain consolidated subsidiaries (“Stock Benefit”).

Stock Compensation I will be paid at the time of retirement in the form of shares of MHFG calculated based on their responsibilities and others. A system is adopted which enables a decrease or forfeiture of the amount depending on the performance of the company or the individual.

Stock Compensation II will be paid in the form of shares of MHFG and will be deferred over three years, which is calculated based on the status of achieving our Five-Year Business Plan. A system is adopted which enables a decrease or forfeiture of the amount depending on the performance of the company or the individual.

Stock Benefit will be paid in the collective form of MHFG’s share which is based on responsibilities in their respective company and the performance evaluation of the Company Group. Reduction and forfeit of the benefit can be occurred in the program.

Upon the payment of stock compensation under the Program, MHFG may, for a certain portion, pay a monetary amount equivalent to the market value of its stock in lieu of stock compensation in accordance with the Rules on Distribution of Shares.

Voting rights related to MHFG’s shares belonging to the trust assets under the trust shall not be exercised.

(2) MHFG’s Shares Outstanding in the Trust

MHFG’s shares outstanding in the trust are recognized as Treasury Stock under Net Assets at the carrying amount (excluding the amount of incidental expenses) in the trust. The carrying amount of such Treasury Stock as of December 31, 2021 was ¥4,949 million for 3,079 thousand shares (the carrying amount as of March 31, 2021 was ¥4,144 million for 2,554 thousand shares).

Reserves for Possible Losses on Loans

In light of the principles set forth in the report entitled “Japanese Financial Services Agency (“JFSA”)’s supervisory approaches to lending business and loan loss provisioning” published by JFSA on December 18, 2019, we have reflected the potential impact of the spread of COVID-19 and its prolongation on Reserves for Possible Losses on Loans for some credit. More specifically, we have estimated the expected loss amount that reflects the impact of the prolongation of COVID-19. The estimate includes the future prospect of business environment of each industry and the forecasted GDP growth rate as major assumptions. There are no material changes in the methods of the above accounting estimates and the major assumptions used in the quarterly consolidated financial statements from those of the previous fiscal year.

Adoption of the Consolidated Taxation System

MHFG and some domestic consolidated subsidiaries of the Group apply the Consolidated Taxation System from the first quarter ended June 30, 2021.

Application of tax-effect accounting to the Transition from the Consolidated Taxation System to the Group Aggregation System

MHFG and some domestic consolidated subsidiaries of the Group record amounts of deferred tax assets and deferred tax liabilities based on the provisions of tax laws prior to amendment under the treatment in Paragraph 3 of “Treatment of the application of the tax-effect accounting in relation to the transition from the consolidated tax system to the aggregate group system” (Practical Solutions No.39 March 31, 2020), without applying the provisions of Paragraph 44 of “Guidance on Accounting Standard for tax-effect accounting” (Implementation Guidance No.28 February 16, 2018), regarding the tax items for which review of the non-consolidated Tax Payment System was implemented in accordance with the transition to the aggregated group system established under the “Act for Partial Revision of the Income Tax Act, etc.” (Act No. 8 of 2020) and the transition to the aggregated group system.
