Notes to Quarterly Consolidated Financial Statements

Changes in Accounting Policies

MHFG has applied “Leases” (IFRS 16 and ASU 2016-02) at some consolidated subsidiaries from the first quarter ended June 30, 2019. Accordingly, lessees recognize assets and liabilities for all leases as a general rule.

In accordance with transitional treatment, MHFG has recognized the impact of this accounting standard cumulatively as of the date of adoption for balances at the beginning of the first quarter ended June 30, 2019.

The impact on the consolidated financial statements for the first quarter ended June 30, 2019 is immaterial.

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, Executive Officer, and Specialist Officer 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 Specialist Officers of MHFG, Mizuho Bank, Ltd., Mizuho Trust & Banking Co., Ltd., and Mizuho Securities Co., Ltd. (the “Company Group”) 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 position in their respective company (“Stock Compensation I”) and the stock compensation program based on the performance evaluation of the Company Group (“Stock Compensation II”).

Stock Compensation I will be paid at the time of retirement in the form of shares of MHFG calculated based on their position. 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 Company Group’s performance, the performance of organizations (in-house companies and units, etc.) that each Company Group Officer is in charge of and the performance of each Company Group Officer. A system is adopted which enables a decrease or forfeiture of the amount depending on the performance of the company or the individual.

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 June 30, 2019 was ¥3,457 million for 18,323 thousand shares (the carrying amount as of March 31, 2019 was ¥3,569 million for 18,917 thousand shares).

(Notes)	1.	Unrealized Gains (Losses) include ¥30,128 million and ¥38,000 million, which were recognized in the statements of income for the year ended March 31, 2019 and the three months ended June 30, 2019, respectively, by applying the fair-value hedge method.
	2.	As for the quarterly consolidated balance sheet amount (consolidated balance sheet amount), fair value of Japanese stocks with a quoted market price is determined based on the average quoted market price, or other reasonable value during the last month of the three months ended June 30, 2019 (last month of the fiscal year ended March 31, 2019), and fair value of securities other than Japanese stocks is determined at the quoted market price if available, or other reasonable value as of June 30, 2019 (March 31, 2019).
	3.	Certain Securities other than Trading Securities (excluding Securities for which it is deemed to be extremely difficult to determine the fair value) are devalued to the fair value, and the difference between the acquisition cost and the fair value is treated as the loss for the three months ended June 30, 2019 (the fiscal year ended March 31, 2019) (impairment (devaluation)), if the fair value (primarily the closing market price as of June 30, 2019 (March 31, 2019)) has significantly deteriorated compared with the acquisition cost (including amortized cost), and unless it is deemed that there is a possibility of a recovery in the fair value.
		The amount of impairment (devaluation) for the fiscal year ended March 31, 2019 was ¥4,736 million.
		The amount of impairment (devaluation) for the three months ended June 30, 2019 was ¥4,995 million.
		The criteria for determining whether a security’s fair value has “significantly deteriorated” are outlined as follows:
		•   Securities whose fair value is 50% or less of the acquisition cost
		•   Securities whose fair value exceeds 50% but is 70% or less of the acquisition cost and the quoted market price maintains a certain level or lower
	4.	Floating-rate Japanese Government Bonds
		Fair values of Floating-rate Japanese Government Bonds, according to our determination that current market prices may not reflect the fair value, are based on the reasonably calculated prices as book value on the quarterly consolidated balance sheet (consolidated balance sheet).
		In deriving the reasonably calculated prices, we used the Discounted Cash Flow method as well as other methods. The price decision variables include the yield of 10-year Japanese Government Bonds and the volatilities of interest rate swap options for 10-year Japanese Government Bonds as underlying assets.
