See Note 2 “Issued accounting pronouncements” for further details.The primary component of the retail portfolio segment is mortgage loans to individuals which obligor category is classified based on past due status. The trigger to reclassify obligors from normal obligors to watch obligors excluding special attention obligors is when the past due status is more than 30 days.Non-impaired loans held by subsidiaries other than MHBK and MHTB constitute other, since their portfolio segments are not identical to those of MHBK and MHTB.Special attention obligors are watch obligors with debt in TDR or 90 days or more delinquent debt. Loans to such obligors are considered impaired.Other industries of domestic includes trade receivables and lease receivables of consolidated VIEs.Impaired loans to foreign borrowers decreased by ¥15,960 million due mainly to the sale of certain loans, partly offset by deterioration of credit status of certain other borrowers.Amounts represent the outstanding balances of nonaccrual loans. The MHFG Group’s policy for placing loans in nonaccrual status corresponds to the Group’s definition of impaired loans.These impaired loans do not require an allowance for loan losses because the MHFG Group has sufficient collateral to cover probable loan losses.The allowance for loan losses on impaired loans includes the allowance for groups of loans which were collectively evaluated for impairment, in addition to the allowance for those loans that were individually evaluated for impairment. The total carrying amount of the groups of loans which were collectively evaluated for impairment at March 31, 2019 and 2020 was ¥257,099 million and ¥260,596 million, respectively.Amounts represent the amount of interest income on impaired loans recognized on a cash basis and included in Interest income on loans in the consolidated statements of income.The majority of total foreign consist of commercial and industrial loans.Amounts represent the book values of loans immediately after the restructurings.Others includes primarily foreign exchange translation.Amounts represent loan balances before deducting unearned income and deferred loan fees.Receivables from brokers, dealers and customers for securities transactions included ¥555,938 million and ¥3,136 million of such receivables of consolidated VIEs at March 31, 2019 and 2020, respectively.

Unearned income is primarily comprised of loan fees received from consumer loan customers when loans are made. This income is deferred and recognized in earnings over the life of the loan.See Note 2 “Issued accounting pronouncements” for further details of the cumulative-effect adjustment for AOCI.The MHFG Group adopted ASU No.2016-01 on April 1, 2018.

The amounts of unfunded commitments related to these investments at March 31, 2019 and 2020 were ¥37 billion and ¥47 billion, respectively.Amounts represent items for which the Group elected the fair value option or for which it applied the practicability exception.Gains (losses) in Earnings are reported in Trading account gains (losses)—net, Foreign exchange gains (losses)—net or Other noninterest income (expenses).Amounts represent total gains or losses recognized in earnings during the period.

In connection with the use of the new allocation methods, the presentation of “Net business profits” has changed to “Net business profits (losses) + Net gains (losses) related to ETFs and others.” Before the change, “Net gains (losses) related to ETFs and others” were included in “Gross profits” of each segment and eliminated in “Others.” In addition, “Amortization of goodwill and others” has been presented as a new item. Figures for the fiscal year ended March 31, 2018 have been restated for the new allocation methods. These changes more appropriately reflect the performance of each of the operating segments in accordance with internal managerial accounting rules and practices. Income and expenses of foreign branches of MHBK and foreign subsidiaries with functional currencies other than Japanese Yen have been translated for purposes of segment reporting using the budgeted foreign currency rates. Prior period comparative amounts for such foreign currency income and expenses have been translated using current period budgeted foreign currency rates.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 plus equity in earnings (losses) of equity method investees—net and others. Measurement of net business profits (losses) is required for regulatory reporting to the Financial Services Agency of Japan.“Gross profits + Net gains (losses) related to ETFs and others” is reported instead of sales reported by general corporations. Gross profits is defined as the sum of net interest income, fiduciary income, net fee and commission income, net trading income and net other operating income. Net gains (losses) related to ETFs and others consist of net gains (losses) on ETFs held by MHBK and MHTB on their non-consolidated basis and net gains (losses) on operating investment securities of MHSC on its consolidated basis.

ROU assets are recognized on balance sheets in connection with the adoption of ASU No.2016-02 on April 1, 2019.This figure includes a leverage ratio buffer required to be met at 50% of the additional loss absorbency requirements applied to the Group as a G-SIB under the finalized Basel III reforms.These inputs are mainly used for determining the fair values of securitization products such as CDO, CLO and ABS, other than RMBS and CMBS.This input is mainly used for determining the fair values of Japanese corporate bonds and foreign corporate bonds.Internal valuation model includes discounted cash flow models and the Black-Scholes option pricing model.This input represents the counterparty default rate derived from the MHFG Group’s own internal credit analyses.Weighted averages are calculated by weighting each input by the relative fair value of the respective financial instruments.ROU assets and lease liabilities are included in Other assets and Other liabilities, respectively, on the consolidated balance sheets.Short-term notes are issued under the laws of Japan in the form of commercial paper.The amounts of commercial paper and short-term notes issued by MHFG’s subsidiaries were ¥941,182 million and ¥333,200 million, respectively, at March 31, 2019, and ¥411,089 million and ¥319,000 million, respectively, at March 31, 2020.On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act, which includes a reduction in the U.S. federal corporate income tax rate from 35% to 21%.
