Summary of Significant Accounting Policies	2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The principal accounting policies applied in the preparation of the consolidated financial statements are set out below. These policies have been consistently applied to all the fiscal years presented, unless otherwise stated. Basis of Preparation Compliance with International Financial Reporting Standards The consolidated financial statements of the Group have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). Basis of measurement The consolidated financial statements have been prepared under the historical cost basis except for the following: • trading assets and liabilities are measured at fair value; • derivative financial instruments are measured at fair value; • financial assets and liabilities at fair value through profit or loss are measured at fair value; • investment securities at fair value through other comprehensive income are measured at fair value; and • liabilities and the assets recognized in consolidated statements of financial position in respect of defined benefit plans are the present value of the defined benefit obligation less the fair value of plan assets. Functional and presentation currency The consolidated financial statements are presented in Japanese yen, which is also the Company’s functional currency. All financial information presented in Japanese yen has been rounded to the nearest million, except as otherwise indicated. Critical accounting estimates and judgments The preparation of the consolidated financial statements in accordance with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise judgment in the process of applying the accounting policies. Actual results may differ from these estimates. The notes to the consolidated financial statements set out areas involving a higher degree of judgment or complexity, or areas where assumptions are significant to the consolidated financial statements, such as allowance for loan losses (Notes 10, 33), fair value of financial instruments (Note 44), impairment of property, plant and equipment (Note 12), impairment of intangible assets (Note 14), provision for interest repayment (Note 21), retirement benefits (Note 24) and deferred tax assets (Note 23). Refer to Note 3 “Critical Accounting Estimates and Judgments” for further information. New and Amended Accounting Standards Adopted by the Group During the fiscal year ended March 31, 2022, a number of amendments to standards have become effective; however, they have not resulted in any material changes to the Group’s accounting policies, except as described below. Interest Rate Benchmark Reform—Phase 2 (Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16) In August 2020, the IASB issued “Interest Rate Benchmark Reform—Phase 2: Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16” in response to the reform of interest rate benchmarks such as interbank offered rates (“IBORs”). The amendments supplement the amendments to IFRS 9 “Financial Instruments,” IAS 39 “Financial Instruments: Recognition and Measurement” and IFRS 7 “Financial Instruments: Disclosures” issued in 2019 and focus on the effects on entities’ financial statements when entities replace the previous interest rate benchmark with an alternative interest rate benchmark as a result of the reform. The amendments provide a practical expedient for modifications of financial assets and financial liabilities required as a direct consequence of the reform and made on an economically equivalent basis and a temporary exception to specific hedge accounting requirements, and support entities in providing useful information to users of financial statements. The amendments are effective for annual periods beginning on or after January 1, 2021. On April 1, 2021, the Group adopted the amendments. Consolidation Subsidiaries Subsidiaries are all entities controlled by the Group. The Group controls an entity when it is exposed, or has rights, to variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. The Group considers all facts and circumstances whether it controls an entity. Where the relevant activities are directed through voting or similar rights, the Group considers that it controls an entity if it has the existing rights that give it the current ability to direct the operating and financing policies of the entity, in general by having a shareholding of more than 50% of the voting rights. The existence and effect of potential voting rights that are deemed to be substantive are taken into account when assessing whether the Group controls another entity. Where the voting rights are not the dominant factor in deciding who controls the entity, the assessment of control is more complex and requires greater use of judgment. The Group assesses whether it controls an entity considering all facts and circumstances, such as the purpose and design of the entity, the relevant activities and how to make decisions about those activities. The Group also determines whether it is acting as an agent or a principal parties and therefore does not control the entity. To make such judgments, the Group considers the overall relationship, especially all of the following factors: the scope of its decision-making authority over the entity, the rights held by other parties, the remuneration to which it is entitled in accordance with the remuneration agreement, and its exposure to variability of returns from other interests that it holds in the entity. The Group reassesses whether it controls an entity if facts and circumstances indicate that there are changes to one or more of the elements of control. Subsidiaries are fully consolidated from the date on which the Group obtains control. They are deconsolidated from the date on which the Group loses control. The acquisition method is used to account for the business combinations including the acquisition of subsidiaries by the Group. The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the acquisition-date fair values of the assets transferred, the liabilities incurred and the equity interests issued. Identifiable assets acquired and liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. The Group’s previously held equity interest in the acquiree is remeasured at fair value at the acquisition date and any gain or loss is recognized in profit or loss. For each business combination, the Group measures any non-controlling non-controlling non-controlling non-controlling Inter-company transactions, balances and unrealized gains on transactions between the Group companies are eliminated on consolidation. Unrealized losses are also eliminated unless the transaction provides evidence of impairment of the asset transferred. The accounting policies of subsidiaries have been adjusted where necessary to ensure consistency with the accounting policies adopted by the Group. Non-controlling Changes in the Group’s ownership interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions. Interests in the equity of subsidiaries not attributable to the Group are reported in the consolidated statements of financial position as a separate component of equity as non-controlling non-controlling Associates and joint ventures An associate is an entity over which the Group has significant influence, but does not control the financial and operating policy decisions of the entity. Significant influence is generally presumed to exist when the Group holds 20% or more, but less than 50%, of the voting rights. Entities that are jointly controlled by more than one party, including the Group, may be determined to be a joint venture. The Group accounts for investments in associates and joint ventures using the equity method from the date on which they become associates or joint ventures. The Group discontinues the use of the equity method from the date on which the Group ceases to have significant influence or joint control over the investees. Under the equity method, the Group’s investments in associates and joint ventures are initially recognized at cost. The carrying amount of the investments are subsequently increased or decreased to recognize the Group’s share of the post-acquisition profit or loss of the associate or joint venture and other movements included directly in the equity of the associate or joint venture. The Group’s share of the results of associates and joint ventures is based on the financial statements of its associates and joint ventures, adjusted to conform with the accounting policies of the Group. Profits on transactions between the Group and its associates and joint ventures are eliminated to the extent of the Group’s interest in the associates or joint ventures. Losses are also eliminated to the extent of the Group’s interest in the associates or joint ventures unless the transaction provides evidence of impairment in the asset transferred. The carrying amounts of the investments in associates and joint ventures include goodwill (net of any accumulated impairment loss) arising on the acquisition of the interests in the entities. Because goodwill arising on the acquisition of the interest in an associate or joint venture is not separately recognized, it is not tested for impairment separately. Instead, the entire carrying amount of the investment in an associate or joint venture is tested for impairment as a single asset by comparing its recoverable amount, which is the higher of value in use and fair value less costs to sell, with its carrying amount, whenever there is any objective evidence that the investment is impaired. An impairment loss recognized in prior periods for the investment is reversed only if there has been a change in the estimates used to determine the recoverable amount of the investment since the last impairment loss was recognized. If this is the case, the carrying amount of the investment is increased to its recoverable amount. That increase is a reversal of an impairment loss. When the Group’s share of losses in an associate or joint venture exceeds the Group’s carrying amount of the investment, the Group does not recognize further losses, unless it has a binding obligation or has made payments on behalf of the entity. Segment Reporting The Group determines its operating segments based on the management approach, which requires operating segments to be identified on the basis of internal reports about components of the entity that are regularly reviewed by management, in order to allocate resources to a segment and to assess its performance. Foreign Currency Translation Items included in the financial statements of each of the Group companies are measured using the currency of the primary economic environment in which the company operates (“the functional currency”). The consolidated financial statements are presented in Japanese yen, which is also the Company’s functional currency. Transactions and balances Foreign currency transactions that are denominated or settled in a foreign currency are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Monetary items denominated in foreign currencies are translated using the exchange rate at the end of the reporting period. Foreign exchange gains and losses resulting from the retranslation and settlement of monetary items are recognized in the consolidated income statements. Non-monetary Non-monetary functional Foreign operations The assets and liabilities of foreign operations are translated into the presentation currency of the Group using the exchange rate at the end of the reporting period, and their income statements are translated using the exchange rates at the dates of the transactions or average exchange rates where these approximate to actual rates. The exchange differences arising on the translation of a foreign operation are included in other comprehensive income within equity and subsequently included in profit or loss on the disposal or partial disposal of the operation. Financial Assets Regular way purchases and sales of financial assets are recognized and derecognized on the trade date—the date on which the Group commits to purchase or sell the assets. Financial assets are derecognized when the contractual rights to receive cash flows from the financial assets have expired or where the Group has transferred substantially all the risks and rewards of ownership of the financial assets at a consolidated level. The Group consolidates all subsidiaries in accordance with IFRS 10 “Consolidated Financial Statements” before determining derecognition of financial assets. IFRS 9 requires all financial assets, including entire hybrid instruments, to be classified into three measurement categories, namely, amortized cost, fair value through other comprehensive income (“FVOCI”) and fair value through profit or loss (“FVPL”), based on the business model within which they are held and their contractual cash flow characteristics. The Group has assessed the business models based on facts and circumstances at a portfolio level. Factors that are considered in determining the business model include policies and objectives for the relevant portfolio, how the performance and risks of the portfolio are managed, evaluated and reported to management, and the level of sales activity. The Group has assessed the contractual cash flow characteristics of financial assets with reference to whether the contractual cash flows are solely payments of principal and interest (“SPPI”). Principal is defined as the fair value of the financial asset at initial recognition but it may change over the life of the financial asset as amounts are repaid. Interest is defined as consideration for the time value of money and the credit risk associated with the principal amount outstanding during a particular period of time. It can also include consideration for other basic lending risks such as liquidity risk and costs such as administrative costs associated with holding the financial asset for a particular period of time, as well as a profit margin. In assessing whether the contractual cash flows meet the conditions for SPPI, the Group considers the contractual terms of the financial asset. This includes assessing whether the financial asset contains a contractual term that could change the contractual cash flows so that it would not meet the conditions for SPPI, including leverage features, contingent events that would change the amount or timing of cash flows, contractual terms that limit the Group’s claim to cash flows from specified assets, and features that modify consideration of the time value of money. Financial assets measured at amortized cost Financial assets are measured at amortized cost if they are held within a business model whose objective is to hold the assets in order to collect contractual cash flows, and their contractual cash flows are SPPI. These financial assets are mainly included in “Loans and advances” and also in “Investment securities” in the consolidated statements of financial position. They are initially recognized at fair value plus transaction costs that are directly attributable to the acquisition of the financial assets, and are subsequently measured at amortized cost using the effective interest method. Interest income on these financial assets using the effective interest method is recognized Financial assets measured at fair value through other comprehensive income Financial assets are measured at FVOCI if they are held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets, and their contractual cash flows are SPPI. Financial assets measured at FVOCI are included in “Investment securities” in the consolidated statements of financial position. They are initially recognized at fair value plus transaction costs that are directly attributable to the acquisition of the financial assets, and are subsequently measured at fair value. Gains and losses arising from changes in the fair value of these financial assets are recognized in other comprehensive income, until they are derecognized. At the time of derecognition, the cumulative gains or losses previously recognized in other comprehensive income are reclassified to profit or loss and are recognized in “Net investment income” in the consolidated income statements. Interest income calculated using the effective interest method, foreign currency gains and losses, and impairment gains and losses are recognized in “Net interest income,” “Net trading income” and “Impairment charges on financial assets” in the consolidated income statements, respectively. In addition, the Group makes an irrevocable election at initial recognition, for particular non-trading Financial assets measured at fair value through profit or loss Any financial assets that do not meet the criteria of amortized cost or FVOCI are classified as FVPL, unless the Group makes an irrevocable election for non-trading Financial assets are classified as held for trading and are included in “Trading assets” in the consolidated statements of financial position, if they are acquired principally for the purpose of selling in the near term or if they are part of a portfolio of identified financial instruments that are managed together and for which there is evidence of a recent actual pattern of short-term profit-taking. Derivatives which are not designated as hedging instruments are classified as held for trading, and all derivatives are included in “Derivative financial instruments” in the consolidated statements of financial position. All derivatives are carried as assets when the fair value is positive and as liabilities when the fair value is negative. Financial assets mandatorily measured at FVPL, other than those held for trading and derivatives, are included in “Financial assets at fair value through profit or loss” in the consolidated statements of financial position. The financial assets mentioned above are initially recognized at fair value with transaction costs being recognized in profit or loss, and are subsequently measured at fair value. Gains and losses arising from changes in the fair values of trading assets and derivatives held for trading, and interest and dividend income on trading assets are included in “Net trading income” in the consolidated income statements. Gains or losses arising from financial assets mandatorily measured at FVPL are included in “Net income (loss) from financial assets and liabilities at fair value through profit or loss” in the consolidated income statements. Additionally, financial assets measured at amortized cost or FVOCI can be designated at initial recognition to be measured at FVPL in order to eliminate or significantly reduce a measurement or recognition inconsistency. The Group does not make this designation. Financial Liabilities Financial liabilities measured at amortized cost Financial liabilities, except for financial liabilities measured at FVPL Financial liabilities measured at fair value through profit or loss Financial liabilities measured at FVPL consist of financial liabilities held for trading, derivatives whose fair values are negative and financial liabilities designated at FVPL. Financial liabilities are classified as held for trading if they are incurred principally for the purpose of repurchasing in the near term or if they are part of a portfolio of identified financial instruments that are managed together and for which there is evidence of a recent actual pattern of short-term profit-taking. Financial liabilities held for trading are included in “Trading liabilities” in the consolidated statements of financial position. Trading liabilities are initially recognized at fair value with transaction costs being recognized in profit or loss, and are subsequently measured at fair value. Gains and losses arising from changes in the fair values of trading liabilities and interest expense on trading liabilities are included in “Net trading income” in the consolidated income statements. For derivatives other than the component of hybrid instrument, refer to “Financial assets measured at fair value through profit or loss.” The derivative component of a hybrid instrument containing both a derivative and non-derivative The Group applies a fair value option to certain financial liabilities which were issued by the Group’s securities subsidiary. As part of risk management, the Group enters into derivative transactions to offset the profit or loss of financial liabilities containing embedded derivatives, designated at FVPL under the fair value option. The Group can make an irrevocable election for each individual financial liability at initial recognition to designate it as measured at FVPL, if it meets one of the following criteria: • The designation eliminates or significantly reduces a measurement or recognition inconsistency (referred to as “an accounting mismatch”) that would otherwise arise from measuring assets or liabilities or recognizing the gains and losses on them on different bases; • A group of financial liabilities or financial assets and financial liabilities is managed, and its performance is evaluated on a fair value basis, in accordance with a documented risk management or investment strategy, and information about the group is provided internally on that basis to the board of directors; or • The financial liability contains one or more embedded derivatives which significantly modify the cash flows and it is not clear with no analysis that separation is prohibited. The financial liabilities designated at FVPL are presented as “Financial liabilities designated at fair value through profit or loss” in the consolidated statements of financial position. Those liabilities are initially recognized at fair value with transaction costs being recognized in profit or loss, and are subsequently measured at fair value. The amount of changes in their fair values that is attributable to changes in own credit risk of the liabilities is recognized in other comprehensive income and subsequently not transferred to profit or loss. The amount of changes in their fair values except for the effects of changes in their own credit risk, gains or losses on derecognition and interest expense are included in “Net income (loss) from financial assets and liabilities at fair value through profit or loss” in the consolidated income statements. Financial liabilities are derecognized when they have been redeemed or otherwise extinguished. Hedge Accounting The Group applies fair value hedge accounting and hedge accounting of net investments in foreign operations, in order to reflect the effect of risk management activities on its consolidated financial statements. Fair value hedges The Group applies fair value hedge accounting in order to reflect in its consolidated financial statements the effect of risk management activities to mitigate the risk of changes in the fair value of certain fixed rate financial assets and liabilities. The Group designates certain interest rate derivatives as hedging instruments. Changes in fair values of hedging instruments are recognized in the consolidated income statements, together with changes in fair value of the hedged item attributable to the hedged risk. The hedging gain or loss on the hedged item held at amortized cost adjusts the carrying amount of the hedged item, and is recognized in “Net trading income” in the consolidated income statements. If the hedged item is a financial asset measured at FVOCI, the hedging gain or loss on the hedged item is recognized in “Net trading income” in the consolidated income statements. If the hedge no longer meets the criteria for hedge accounting for reasons other than the derecognition of the hedged item, the adjustment to the hedged item for which the effective interest method is used, is amortized to profit or loss over the period to maturity of the hedged item. When the hedged item is derecognized, the adjustment is recognized immediately in the consolidated income statements. The Group also applies fair value hedge accounting in order to reflect in its consolidated financial statements the effect of risk management activities to mitigate the risk of changes in fair values of certain equity instruments elected to be measured at FVOCI. The Group designates equity derivatives as hedging instruments. Both the effective portion and ineffective portion of changes in the fair value of the hedging instruments are recognized in other comprehensive income, and amounts presented in other comprehensive income are not subsequently transferred to profit or loss. Hedges of net investments in foreign operations The Group applies hedge accounting of net investments in foreign operations in order to reflect in its consolidated financial statements the effect of risk management activities to mitigate the foreign currency risk of exchange differences arising from the translation of net investments in foreign operations. The Group designates currency derivatives and foreign currency denominated financial liabilities as hedging instruments. The effective portion of the gain or loss on the hedging instruments is recognized in other comprehensive income, whereas the ineffective portion of the gain or loss on the hedging instruments is recognized in “Net trading income” in the consolidated income statements. The cumulative gain or loss recognized in other comprehensive income is reclassified to profit or loss on the disposal or partial disposal of foreign operations. For further information about hedge accounting, see Note 7 “Derivative Financial Instruments and Hedge Accounting—Hedge accounting.” Interest Rate Benchmark Reform The Group applies “Interest Rate Benchmark Reform, Amendments to IFRS 9, IAS 39 and IFRS 7.” The amendments provide reliefs from applying specific hedge accounting requirements to hedging relationships directly affected by the interest rate benchmark reform only if the reform gives rise to uncertainties. The reliefs aim to ensure that the interest rate benchmark reform does not result in the discontinuance of hedge accounting. In accordance with the transition provisions, the amendments have been adopted retrospectively to hedging relationships that existed at the beginning of the reporting period or were designated thereafter. The reliefs adopted by the Group are described below. • Prospective assessments The Group has assumed that the interest rate benchmarks on which the hedged risk or the cash flows of the hedging instrument is based are not altered as a result of the interest rate benchmark reform in assessing whether there is an economic relationship between the hedged item and the hedging instrument. • Hedge of a non-contractually The Group has assessed whether a non-contractually Offsetting Financial Instruments Financial assets and liabilities are offset and the net amount is reported in the consolidated statements of financial position, only if the Group currently has a legally enforceable right to set off the recognized amounts and intends to settle on a net basis or to realize the asset and settle the liability simultaneously. In all other situations, they are presented on a gross basis. Fair Value Measurement Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining the fair value, the Group gives the highest priority to a quoted price in an active market for identical assets or liabilities. A market is regarded as active if transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis. If there is no active market for the asset or liability, the Group uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure the fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. In cases where the Group manages a group of financial assets and financial liabilities on the basis of its net credit risk exposure, the fair value of the group of financial assets and financial liabilities is measured on the basis of the price that would be received to sell a net long position (i.e., an asset) or paid to transfer a net short position (i.e., a liability) for the credit risk exposure provided that certain criteria set forth in IFRS 13 “Fair Value Measurement” are met. Details of fair value measurement are described in Note 44 “Fair Value of Financial Assets and Liabilities.” Recognition of Deferred Day One Profit and Loss The best evidence of the fair value of a financial instrument at initial recognition is normally the transaction price (i.e., the fair value of the consideration given or received). However, if the fair value at initial recognition is not evidenced by a quoted price in an active market for an identical asset or liability nor based on a valuation technique that uses only data from observable markets, the difference between the fair value at initial recognition and the transaction price, commonly referred to as “day one profit and loss,” is not recognized as a gain or loss but is adjusted to be deferred. The Group has certain financial instruments, such as derivatives, hybrid financial instruments and certain loans and advances classified as FVPL where fair value is determined using valuation techniques for which not all inputs are observable in a market. Such a financial instrument is initially recognized at the transaction price which may be different from the fair value, and the day one profit and loss is not recognized as a gain or loss. The timing of recognition of the deferred day one profit and loss is determined on an instrument by instrument basis. It is either amortized over the life of the transaction, deferred until fair value of the instrument can be determined using data from observable markets, or realized due to redemption or sales of the instrument . Repurchase and Reverse Repurchase Agreements, and Securities Borrowing and Lending Agreements In the ordinary course of business, the Group lends or sells securities under agreements to repurchase them at a predetermined price on a future date (“repos”). Since substantially all the risks and rewards of ownership are retained by the Group, the securities remain on the consolidated statements of financial position and a liability is recorded in respect of the consideration received. On the other hand, the Group borrows or purchases securities under agreements to resell them at a predetermined price on a future date (“reverse repos”). Since the Group does not retain the risks and rewards of ownership of the financial assets, these transactions are treated as collateralized loans and the securities are not included in the consolidated statements of financial position. The Group measures repos and reverse repos at amortized cost. The difference between the sale and purchase price is accrued over the life of the transactions. Securities lent to counterparties remain on the consolidated statements of financial position. Securities borrowed are not recognized in the consolidated statements of financial position, unless these are sold to third parties, at which point the obligation to repurchase the securities is measured at fair value and included in “Trading liabilities” in the consolidated statements of financial position and any subsequent gain or loss is included in “Net trading income” in the consolidated income statements. For the fiscal years ended March 31, 2022 and 2021, there were no transactions pursuant to repurchase agreements, securities lending transactions or other transactions involving the transfer of financial assets with an obligation to repurchase such transferred assets that were treated as sales and hence derecognized for accounting purposes. Impairment of Financial Assets The expected credit losses (“ECL”) model is used for the recognition of impairment loss under IFRS 9. The ECL model applies to financial assets measured at amortized cost, and debt instruments at FVOCI, lease receivables, certain loan commitments and financial guarantee contracts. Under the ECL model, an entity is

Critical Accounting Estimates and Judgments	3 CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS The consolidated financial statements are influenced by estimates and management judgments, which necessarily have to be made in the course of preparation of the consolidated financial statements. Estimates and judgments are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances, and which are continually evaluated. Allowance for Loan Losses The allowance for loan losses is measured under the ECL model which requires the use of complex models and significant assumptions about future economic conditions and credit behavior. A number of significant judgments are also required in applying the accounting requirements for measuring ECL, such as: • qualitative assessment in determining obligor grades; • determining criteria for a significant increase in credit risk since initial recognition; • measuring ECL by choosing appropriate models and assumptions; • incorporating forward-looking information into the ECL measurement by obligor grading, forecast range of macroeconomic scenarios, and additional ECL adjustments if the current circumstances, events or conditions at relevant portfolio level are not fully reflected in the ECL model; and • estimating the expected future cash flows by taking into account factors such as historical loss information, the appropriateness of the borrower’s business plan or operational improvement plan, the status of progress of its plan, the overall support from financial institutions, and the realizable value of any collateral held. For the fiscal year ended March 31, 2022, the obligor grading, macroeconomic factors and additional ECL adjustments used to determine the final ECL reflected the current and forward-looking impact of the situation in Russia and Ukraine and the COVID-19 The obligor grades were reviewed based on the most recent information available as appropriate. For the fiscal year ended March 31, 2022, the obligor grades of a number of Russian borrowers affected by the situation in Russia and Ukraine and certain large borrowers were downgraded to the extent that the credit risk on loans and advances to such borrowers was determined to be significantly increased since initial recognition and their allowance for loan losses was measured at an amount equal to the lifetime ECL. The macroeconomic scenarios for incorporating forward-looking information in the ECL measurement were updated, reflecting the recent economic forecasts. Although the Group understands that there is significant uncertainty in predicting the severity and duration of Russia’s aggression against Ukraine, the timing of the economic recovery from the COVID-19 Group assumed that the Japanese and global economy will continue to recover from the COVID-19 For the fiscal year ending March 31, 2023 2024 (%) Japanese GDP 2.8 1.9 Global GDP 3.9 3.3 In determining the need for making additional ECL adjustments, the Group considered whether there is an increase in the credit risk for some portfolios which had a material adverse impact resulting from the sanctions imposed in connection with Russia’s aggression against Ukraine or from the COVID-19 COVID-19 Management estimates and judgments may change from time to time as the economic environment changes or new information becomes available. Changes in these estimates and judgments will result in a different allowance for loan losses and may have a direct impact on impairment charges. Allowance for loan losses amounted to ¥993,054 million and ¥849,287 million at March 31, 2022 and 2021, respectively. For additional information, refer to Note 10 “Loans and Advances.” Fair Value of Financial Instruments The fair values of financial instruments where no active market exists or where quoted prices are not otherwise available are determined by using valuation techniques. In these cases, inputs to valuation techniques are based on observable data with respect to similar financial instruments or by using models. Where observable inputs are not available, the fair value is estimated based on appropriate assumptions that a market participant would take into account. Where valuation techniques (for example, models) are used to determine fair values, they are validated and periodically reviewed. The Group certifies significant valuation models before they are used, and calibrates them to ensure that outputs reflect actual data and comparative market prices. To the extent practical, models use only observable data; however, inputs such as credit risk (both own and counterparty), volatilities and correlations require management to make estimates. Changes in assumptions about these factors could affect the fair values of these financial instruments. More details about the Group’s valuation techniques, significant unobservable inputs used in determining fair values and sensitivity analyses are given in Note 44 “Fair Value of Financial Assets and Liabilities.” Impairment of Property, Plant and Equipment The Group has property, plant and equipment, which consist of assets for rent, land, buildings, right of use assets and others. Property, plant and equipment are tested for impairment if events or changes in circumstances indicate that it may not be recoverable at the end of each reporting period. If any such indication exists, then its recoverable amount is estimated. The process to determine the recoverable amount is inherently uncertain because such recoverable amount is determined based on management estimates and judgments. Changes in management judgments may result in different impairment test results and different impairment amounts recognized. For the fiscal years ended March 31, 2022, 2021 and 2020, impairment losses on property, plant and equipment were ¥43,708 million, ¥10,959 million and ¥79,947 million, respectively. For additional information, refer to Note 12 “Property, Plant and Equipment.” Impairment of Intangible Assets Impairment of goodwill Goodwill is tested for impairment on an annual basis or more frequently if events or changes in circumstances indicate that it may not be recoverable. If any such indication exists, then its recoverable amount is estimated. The process to determine the recoverable amount is inherently uncertain because such recoverable amount is determined based on a number of management estimates and judgments. The Group determines the recoverable amount using the estimated future cash flows, pre-tax pre-tax Impairment of other intangible assets The Group has other intangible assets, not including goodwill, which consist of software, contractual customer relationships, trademarks and others. These are divided into other amortizing intangible assets and other non-amortizing non-amortizing Provision for Interest Repayment Provision for interest repayment represents management’s estimate of future claims for the refund of so-called Restriction Act (ranging from 15% to 20%) up to the 29.2% maximum rate permitted under the Act Regulating the Receipt of Contributions, Receipt of Deposits and Interest Rates), taking into account historical experience such as the number of customer claims for a refund, the amount of repayments and the characteristics of customers, and the length of the period during which claims are expected to be received in the future. Management estimates and judgments may change from time to time as the legal environment and market conditions change or new information becomes available. Changes in these estimates and judgments could affect the balance of provision for interest repayment. Provision for interest repayment is recorded in provisions as a liability, and it totaled ¥135,123 million and ¥141,201 million at March 31, 2022 and 2021, respectively. For additional information, refer to Note 21 “Provisions.” Retirement Benefits The Group has defined benefit plans such as defined benefit pension plans and lump-sum The difference between the fair value of the plan assets and the present value of the defined benefit obligation at the end of the reporting period is recognized as assets and liabilities in the consolidated statements of financial position. When this calculation for each plan results in a benefit to the Group, the recognized asset is limited to the present value of any economic benefits available in the form of refunds from the plan or reductions in future contributions to the plan (“asset ceiling”). An economic benefit is available to the Group, if it is realizable during the life of the plan or on settlement of the plan obligation. The net total of assets and liabilities in the consolidated statements of financial position amounted to net assets of ¥508,496 million and ¥480,053 million at March 31, 2022 and 2021, respectively. For additional information, refer to Note 24 “Retirement Benefits.” Deferred Tax Assets Deferred tax assets relating to tax losses carried forward and deductible temporary differences are recognized, only to the extent that it is probable that future taxable profit will be available against which the tax losses carried forward and the deductible temporary differences can be utilized. This assessment requires significant management estimates and judgments. Future taxable profit is estimated based on, among other relevant factors, forecasted results of operations, which are based on historical financial performance and the business plans that management believes to be prudent and feasible. While the Group carefully assesses the realization of tax losses carried forward and deductible temporary differences, the actual taxable profit in the future may be less than the forecast. The deferred tax assets amounted to ¥58,981 million and ¥28,958 million in the consolidated statements of financial position at March 31, 2022 and 2021, respectively, while the net total of deferred tax assets and liabilities amounted to net liabilities of ¥200,299 million and ¥ million at March 31, 2022 and 2021, respectively.

Segment Analysis	4 SEGMENT ANALYSIS Business Segments The Group’s business segment information is prepared based on the internal reporting system utilized by management to assess the performance of its business segments. The Group has four main business segments: the Wholesale Business Unit, the Retail Business Unit, the Global Business Unit, which was renamed from the International Business Unit in April 2020, and the Global Markets Business Unit, with the remaining operations recorded in Head office account and others. Wholesale Business Unit The Wholesale Business Unit provides comprehensive solutions primarily for corporate clients in Japan that respond to wide-ranging client needs in relation to financing, investment management, risk hedging, settlement, M&A and other advisory services, digital services and leasing services. This business unit mainly consists of the wholesale businesses of SMBC, SMBC Trust Bank Ltd. (“SMBC Trust Bank”), Sumitomo Mitsui Finance and Leasing Company, Limited (“SMFL”), SMBC Nikko Securities, Sumitomo Mitsui Card Company, Limited (“Sumitomo Mitsui Card”) and SMBC Finance Service Co., Ltd. (“SMBC Finance Service”), which changed its corporate name from Cedyna Financial Corporation upon merger with former SMBC Finance Service Co., Ltd. on July 1, 2020. Retail Business Unit The Retail Business Unit provides financial services to consumers residing in Japan and mainly consists of the retail business of SMBC, SMBC Trust Bank, SMBC Nikko Securities, Sumitomo Mitsui Card, SMBC Finance Service and SMBC Consumer Finance Co., Ltd. This business unit offers a wide range of products and services for consumers, including wealth management services, settlement services, consumer finance and housing loans, in order to address the financial needs of all individual customers. Global Business Unit The Global Business Unit supports the global businesses of a diverse range of clients, such as Japanese companies operating overseas, non-Japanese Global Markets Business Unit The Global Markets Business Unit offers solutions through foreign exchange products, derivatives, bonds, stocks, and other marketable financial products and also undertakes asset liability management operations, which help comprehensively control balance sheet liquidity risks and interest rate risks. This business unit consists of the Treasury Unit of SMBC and the global markets businesses of SMBC Nikko Securities. Head office account and others The Head office account and others represent the difference between the aggregate of the Wholesale Business Unit, the Retail Business Unit, the Global Business Unit and the Global Markets Business Unit, and the Group as a whole. It mainly consists of administrative expenses related to headquarters operations and profit or loss from other subsidiaries including The Japan Research Institute, Limited and Sumitomo Mitsui DS Asset Management Company, Limited. It also includes the elimination items related to internal transactions between the Group companies. Measurement of Segment Profit or Loss The business segment information is prepared under the management approach. Consolidated net business profit is used as a profit indicator of banks in Japan. Consolidated net business profit of each segment is calculated by deducting general and administrative expenses (i.e., the total of personnel expense, non-personnel Information regarding the total assets of each segment is not used by management in deciding how to allocate resources and assess performance. Accordingly, total assets are not included in the business segment information. Segmental Results of Operations The following tables show the Group’s results of operations by business segment for the fiscal years ended March 31, 2022, 2021 and 2020.

Under IFRS, the Group applies hedge accounting for certain fixed rate debt securities in issue, borrowings, and debt instruments at fair value through other comprehensive income (“FVOCI”), certain equity instruments elected to be measured at FVOCI and net investments in foreign operations. Derivative financial instruments designated as hedging instruments are also categorized as “Risk Management.” Hedge accounting The Group applies fair value hedge accounting and hedge accounting of net investments in foreign operations in order to reflect the effect of risk management activities on its consolidated financial statements. Fair value hedges The Group applies fair value hedge accounting to mitigate the risk of changes in the fair value of certain fixed rate financial assets and liabilities, and the risk of changes in the fair value of certain equity instruments elected to be measured at FVOCI. Changes in the fair value of the assets and the liabilities that are designated as hedged items would not be recognized in profit or loss and those of the equity derivatives that are designated as hedging instruments would be recognized in profit or loss if it did not apply hedge accounting. For more information about the interest rate benchmarks to which the Group’s hedging relationships are exposed, see “Interest Rate Benchmark Reform” in this note. For fair value hedge of interest rate risk, the Group designates as hedging instruments certain interest rate derivatives and establishes a hedge ratio by matching the notional of the derivative financial instruments with the principal amount of the hedged items. The Group assesses hedge effectiveness qualitatively by considering whether the critical terms of the hedged items and hedging instruments closely align. The Group further assesses hedge effectiveness quantitatively by comparing changes in the fair value of the hedged items held at amortized cost arising from changes in the interest rate benchmarks with those of the hedging instruments. If the hedged item is a financial asset measured at FVOCI, in the quantitative assessment, the Group compare changes in the fair value of the hedged items with those of the hedging instruments. Sources of hedge ineffectiveness include basis risk, timing differences between the hedged items and hedging instruments and the effect of the counterparty or the Group’s own credit risk on the fair value of the interest rate derivatives, which is not reflected in the fair value of the hedged item. The gain or loss on the hedging instrument is recognized in “Net trading income” in the consolidated income statements. The hedging gain or loss on the hedged item held at amortized cost adjusts the carrying amount of the hedged item, and is recognized in “Net trading income” in the consolidated income statements. If the hedged item is a financial asset measured at FVOCI, the hedging gain or loss on the hedged item is recognized in “Net trading income” in the consolidated income statements. If the hedge no longer meets the criteria for hedge accounting for reasons other than the derecognition of the hedged item, the adjustment to the hedged item for which the effective interest method is used is amortized to profit or loss over the period to maturity of the hedged item. When the hedged item is derecognized, the adjustment is recognized immediately in the consolidated income statements. For fair value hedge of stock price risk, the Group designates as hedging instruments equity derivatives with underlying instruments identical to the hedged items and establishes a hedge ratio by aligning the number of shares of hedged items with that of equity derivatives used as hedging instruments. The Group assesses hedge effectiveness qualitatively by considering whether the critical terms of the hedged items and hedging instruments closely align and quantitatively by comparing changes in the fair value of the hedged items with those of the hedging instruments. Hedge ineffectiveness may arise from the effect of the counterparty or the Group’s own credit risk on the fair value of the equity derivatives and interest rate risk on the equity derivatives. There are no other sources of hedge ineffectiveness in the hedging relationships. Both the effective portion and ineffective portion of changes in the fair value of the hedging instruments are recognized in other comprehensive income, and amounts presented in other comprehensive income are not subsequently transferred to profit or loss. The tables below represent the amounts related to items designated as hedging instruments at March 31, 2022 and 2021. Line item in the consolidated At March 31, 2022 For the fiscal year Notional (1) Carrying amounts Change in value used Assets Liabilities (In millions) Interest rate risk Interest rate swaps Derivative financial ¥ 8,117,678 ¥ 110,604 ¥ 246,482 ¥ (209,287 ) Interest rate options Derivative financial 170,150 — 3,214 (9,551 ) Stock price risk Equity swaps Derivative financial 19,720 — 2,031 5,191 (1) At March 31, 2022, the notional amount of interest rate swaps with remaining maturities more than 12 months that are designated hedging instruments against interest rate risk is ¥7,355,644 million out of ¥8,117,678 million in total, and that of interest rate options with remaining maturities more than 12 months that are designated hedging instruments against interest rate risk is ¥170,150 million Line item in the consolidated At March 31, 2021 For the fiscal year Notional (1) Carrying amounts Change in value used Assets Liabilities (In millions) Interest rate risk Interest rate swaps Derivative financial ¥ 6,199,507 ¥ 222,553 ¥ 46,666 ¥ (122,874 ) Stock price risk Equity swaps Derivative financial 33,675 — 2,690 (19,215 ) (1) At March 31, 2021, the notional amount of interest rate swaps with remaining maturities more than 12 months that are designated hedging instruments against interest rate risk is ¥5,317,746 million out of ¥6,199,507 million in total, and that of equity swaps with remaining maturities more than 12 months that are designated hedging instruments against stock price risk is ¥33,675 million, equal to the total notional amount. The amounts related to items designated as hedged items at March 31, 2022 and 2021 were as follows: Line item in the consolidated At March 31, 2022 For the fiscal year Carrying amounts Change in value used (In millions) Interest rate risk Debt instruments at FVOCI Investment securities ¥ 1,256,768 ¥ (82,016 ) Debt securities in issue Debt securities in issue 6,569,461 294,332 Borrowings Borrowings 106,489 6,842 Stock price risk Equity instruments at fair value through other comprehensive income Investment securities 21,355 (5,313 ) Line item in the consolidated At March 31, 2021 For the fiscal year Carrying amounts Change in value used (In millions) Interest rate risk Debt securities in issue Debt securities in issue ¥ 6,252,899 ¥ 116,793 Borrowings Borrowings 85,376 2,017 Stock price risk Equity instruments at fair value through other comprehensive income Investment securities 74,564 18,994 As for interest rate risk, the accumulated amount of fair value hedge adjustments on the hedged items was a loss of ¥83,788 million for assets at March 31, 2022 and were a profit of million for liabilities at March 31, 2022 and 2021, respectively. There wer balances remaining in the consolidated statements of financial position for any hedged items that had ceased to be adjusted for hedging gains and losses at March 31, 2022 and 2021. As for interest rate risk, hedge ineffectiveness was included in “Net trading income” in the consolidated income statements, and amounted to a profit of ¥320 Interest Rate Benchmark Reform Interest rate benchmark reform has been undertaken globally to replace or reform interest rate benchmarks such as interbank offered rates (“IBORs”) with alternative rates. This reform gives rise to uncertainties about the timing or the amount of interest rate benchmark-based cash flows of hedged items or of hedging instruments. As a response, the IASB issued in September 2019 “Interest Rate Benchmark Reform: Amendments to IFRS 9, IAS 39 and IFRS 7” that provide temporary relief from applying specific hedge accounting requirements to hedging relationships directly affected by interest rate benchmark reform. The reliefs aim to ensure that the interest rate benchmark reform does not result in the discontinuance of hedge accounting. The Group’s fair value hedge relationships where IBOR-linked derivatives are designated as hedging instruments are directly affected by the interest rate benchmark reform. Those hedging instruments offset the risk exposure the Group aims to manage through hedge relationships. USD LIBOR is the significant interest rate benchmark to which hedging relationships are exposed. The notional amounts of hedging instruments directly affected by the interest rate benchmark reform were ¥5,669,889 million and ¥5,102,495 million at March 31, 2022 and 2021, respectively. The Group put in place a Group-wide IBOR transition project team in May 2019 involving all the Group’s business lines and functions. This project team’s objective was to provide smooth and efficient global coordination for the transition from LIBOR to alternative reference rates, expected to take place by the end of 2021 or the mid-2023. At March 31, 2022, the Group has assumed that remaining financial instruments, referencing USD LIBOR setting, are still exposed to uncertainty about the timing or the amount of interest rate benchmark-based cash flows of hedging instruments. Hedges of net investments in foreign operations The Group applies hedge accounting of net investments in foreign operations to mitigate the foreign currency risk of exchange differences arising from the translation of net investments in foreign operations. The Group hedges the risk of changes in its equity, arising from the movement in the U.S. dollar exchange rate or other exchange rates against Japanese yen. Changes in foreign exchange rates would have an impact on the equity of the Group if it did not apply the hedge accounting. The Group designates as hedging instruments foreign exchange forward contracts and foreign currency denominated financial liabilities. When the hedging instruments are foreign exchange forward contracts, the Group establishes a hedge ratio where the notional amounts on the foreign exchange forward contracts match the carrying amount of the hedged items. The Group designates as hedging instruments only the changes in the fair value of the spot element of the foreign exchange forward contracts, and assesses hedge effectiveness and calculates hedge ineffectiveness by comparing the changes in the carrying amounts of the hedging instruments that are attributable to a change in the spot rate with the changes in the net investments in foreign operations due to a movement in the spot rate. Therefore, the only sources of hedge ineffectiveness that is expected to arise from these hedging relationships are due to the effect of the counterparty or the Group’s own credit risk on the changes in the fair value of the hedging instruments. There are no other sources of hedge ineffectiveness in these hedge relationships. When the hedging instruments are foreign currency denominated financial liabilities, the Group designates them as hedging instruments to the extent that the amounts do not exceed those of the hedged items, and establishes the hedge ratio by aligning the amounts of the hedging instruments with those of the hedged items. The Group assesses hedge effectiveness and calculates hedge ineffectiveness by comparing the changes in the carrying amounts of the liabilities that are attributable to a change in the spot rate with the changes in the net investments in foreign operations due to a movement in the spot rate. Therefore, no hedge ineffectiveness arises. The effective portion of the gain or loss on the hedging instruments is recognized in other comprehensive income, whereas the ineffective portion of the gain or loss on the hedging instruments is recognized in “Net trading income” in the consolidated income statements. The cumulative gain or loss recognized in other comprehensive income is reclassified to profit or loss on the disposal or partial disposal of the foreign operations. On the other hand, changes in the fair value of the forward element of the foreign exchange forward contracts are recognized in “Net trading income” in the consolidated income statements because the Group designates as hedging instruments only the changes in the fair value of the spot element of the foreign exchange forward contracts, as stated above. The tables below represents the amounts related to items designated as hedging instruments at March 31, 2022 and 2021.

(2) The Group recognized goodwill of ¥179,197 million in Head office account and others resulting from the acquisition of Fullerton India Credit Company Limited (“Fullerton India”) on November 30, 2021. For additional information, refer to Note 50 “Acquisitions.” The Group has four main business segments: the Wholesale Business Unit, the Retail Business Unit, the Global Business Unit and the Global Markets Business Unit, with the remaining operations recorded in the Head office account and others. Impairment testing of goodwill Allocating goodwill to cash-generating units For the purpose of impairment testing, goodwill is allocated to cash-generating units or group of cash-generating units, which represent the lowest level within the entity at which goodwill is monitored for internal purposes. At March 31, 2022, the Group allocated goodwill to the Retail Business Unit of SMBC Consumer Finance Co., Ltd. (“SMBC Consumer Finance”) amounting to ¥56,692 million and to the Head office account and others of SMBC Nikko Securities Inc. (“SMBC Nikko Securities”), Sumitomo Mitsui DS Asset Management Company, Limited (“SMDAM”) and Fullerton India amounting to ¥109,629 million and ¥12,678 million and ¥190,986 million, respectively. At March 31, 2021, the Group allocated goodwill to the Retail Business Unit of SMBC Consumer Finance amounting to ¥56,692 million and to the Head office account and others of SMBC Nikko Securities and SMDAM amounting to ¥109,629 million and ¥12,678 million, respectively. The aggregate amounts of other goodwill were ¥26,294 million and ¥24,892 million at March 31, 2022 and 2021, respectively, and they were not considered individually significant. Timing of impairment tests The Group performs impairment tests at least annually and whenever there is an indication that the cash-generating unit may be impaired. Recoverable amount of cash-generating units To determine whether an impairment loss shall be recognized, the carrying amount of a cash-generating unit is compared to its recoverable amount. The recoverable amount of a cash-generating unit is the higher of its fair value less costs to sell and its value in use. Fair value less costs to sell Value in use The financial plans, which are used to estimate the cash flow projections of the cash-generating units, cover three to five years. The cash flow projections beyond the period covered by the financial plans are extrapolated by applying the appropriate growth rates in perpetuity. Key assumptions used in impairment testing The key assumptions used for the value in use calculations for the fiscal years ended March 31, 2022 and 2021 were as follows: SMBC SMBC SMDAM Fullerton For the fiscal year ended March 31, 2022: Pre-tax 8.80 % 9.53 % 12.40 % 17.00 % Growth rate 1.00 % 1.00 % 1.00 % 8.30 % For the fiscal year ended March 31, 2021: Pre-tax 8.42 % 9.73 % 12.80 % — % Growth rate 1.00 % 1.00 % 1.00 % — % Management considers that the pre-tax Pre-tax pre-tax Growth rate Management believes that there were no reasonably possible changes in any of the key assumptions that would lead to the recoverable amounts of the cash-generating units being below these carrying amounts for the fiscal years ended March 31, 2022 and 2021. Recognition of Impairment Losses If the recoverable amount of the cash-generating unit is less than its carrying amount, the carrying amount of the cash-generating unit is reduced to its recoverable amount, and this reduction is recognized as impairment loss of goodwill. The recoverable amount of SMDAM was determined based on the value in use. For the fiscal year ended March 31, 2021, the value in use of SMDAM decreased to less than its carrying amount, primarily due to the revision of the business plan and the key assumptions. As a result, the Group recognized an impairment loss of ¥42,398 million on the goodwill relating to SMDAM for the fiscal year ended March 31, 2021. The impairment losses on goodwill are included in “Other expenses” in the consolidated income statements. Other intangible assets The table below shows the changes in other intangible assets for the fiscal years ended March 31, 2022 and 2021.

The amounts of research and development expenditure recognized as expenses for the fiscal years ended March 31, 2022, 2021 and 2020 were ¥35 million, ¥60 million and ¥78 million, respectively, and they were included in “General and administrative expenses” in the consolidated income statements. Other intangibles at March 31, 2022 and 2021 include leasehold rights, amounting to ¥6,639 million and ¥6,619 million, respectively, which are rights to use land for the purpose of owning the buildings. Since the Group has a long history of renewal, these contracts are not expected to be terminated in the foreseeable future. Leasehold rights are expected to generate cash flows for an indefinite period of time. They are not amortized but are tested for impairment annually, irrespective of whether there is any indication of impairment. Recognition of Impairment Losses The Group recognized impairment losses software belonging to the SMBC retail banking unit and impairment losses for software belonging to the SMBC Trust Bank’s retail banking business unit. For the fiscal year ended March 31, 2022, the COVID-19 . In addition, the Group recognized impairment losses on software belonging to the SMBC Trust Bank’s retail banking business unit. The Group recognized the software as corporate assets. To determine whether they might be impaired, the Group allocated the software to the group of cash-generating units, which is the SMBC Trust Bank’s retail banking business unit, and compared the carrying amount of that group of cash-generating units, including the carrying amount of the software allocated to that group of units, with the recoverable amount of that group of units. The recoverable amount was determined based on the value in use considering the estimated future cash flows. The discount rate used to estimate the value in use of SMBC Trust Bank’s retail banking business unit was approximately %.

Provisions	21 PROVISIONS The following table presents movements by class of provisions for the fiscal years ended March 31, 2022 and 2021. Provision for Other provisions Total (In millions) Balance at April 1, 2020 ¥ 143,429 ¥ 56,624 ¥ 200,053 Additional provisions 39,000 34,374 73,374 Amounts used (40,572 ) (8,418 ) (48,990 ) Unused amounts reversed (559 ) (27 ) (586 ) Amortization of discount and effect of change in discount rate (97 ) 147 50 Others — 373 373 Balance at March 31, 2021 141,201 83,073 224,274 Additional provisions 32,000 20,725 52,725 Amounts used (37,674 ) (10,648 ) (48,322 ) Unused amounts reversed — (655 ) (655 ) Amortization of discount and effect of change in discount rate (404 ) 145 (259 ) Others — 21 21 Balance at March 31, 2022 ¥ 135,123 ¥ 92,661 ¥ 227,784 Provision for Interest Repayment Japan has two laws restricting interest rates on loans. The Interest Rate Restriction Act sets the maximum interest rates on loans ranging from 15% to 20%. The Act Regulating the Receipt of Contributions, Receipt of Deposits and Interest Rates capped the interest rate on loans at 29.2% up to June 2010. Interest rates on loans greater than the range of 15-20% In January 2006, judicial decisions strictly interpreted the conditions under which consumer finance companies may retain gray zone interest. As a result, claims for refunds of gray zone interest have increased, and consumer lending and credit card companies have recorded a provision for claims for refunds of gray zone interest. In December 2006, the Government of Japan made amendments to laws regulating money lenders to implement regulatory reforms affecting the consumer finance industry. As a result, in June 2010, the maximum legal interest rates on loans were reduced to the range of 15-20%, The provision for interest repayment is calculated by estimating the future claims for the refund of gray zone interest, taking into account historical experience such as the number of customer claims for a refund, the amount of repayments and the characteristics of customers, and the length of the period during which claims are expected to be received in the future. Of these historical experiences, the number of customer claims for the refund has a significant effect on the amount of the provision, and the historical number of customer claims to the Group was 91 thousand, 89 thousand and 95 thousand for the fiscal years ended March 31, 2022, 2021 and 2020, respectively. The timing of the settlement of these claims is uncertain. The decrease in the provision for interest repayment for the fiscal year ended March 31, 2022 was primarily due to the use of the provision during the year, which was partially offset by additional provisions as a result of the estimation of the future claims for the refund. Other Provisions Other provisions include asset retirement obligations and provisions for loan commitments, reimbursement of deposits, point programs and litigation claims. Most of these provisions occurred in the normal course of business and none of them were individually significant at March 31, 2022 and 2021.

The Company had adopted the consolidated corporate-tax corporate-tax the parent company and its wholly owned domestic subsidiaries (a “tax consolidated group”), and any unused tax losses carried forward, except for certain specified consolidated tax losses carried forward, by one company could be used by another company within the tax consolidated group for Japanese national corporation tax purposes. Therefore, the deferred tax assets relating to deductible temporary differences and tax losses carried forward were recognized on a consolidated basis, but only to the extent that it was probable that future consolidated taxable profits would be available against which the deductible temporary differences and tax losses carried forward could be utilized. On March 31, 2020, the Government of Japan promulgated an amendment to the Corporation Tax Act, which revised the consolidated corporate-tax The deferred tax assets of the Company and its wholly owned domestic subsidiaries, which adopted the consolidated corporate-tax The following table shows the amounts of deductible temporary differences and tax losses carried forward by expiration date at March 31, 2022 and 2021 for which no deferred tax assets were recognized.

The amount of those deductible temporary differences was ¥833 billion and ¥1,041 billion at March 31, 2022 and 2021, respectively. At March 31, 2022 and 2021, the taxable temporary differences associated with investments in subsidiaries, associates and joint ventures for amounted to ¥3,307 billion and ¥2,787 billion, respectively.

Retirement Benefits	24 RETIREMENT BENEFITS Defined Benefit Plans SMBC and some of the Company’s other subsidiaries have various defined benefit plans such as defined benefit pension plans and lump-sum SMBC’s defined benefit plans account for the vast majority of the defined benefit obligations and plan assets in the Group. SMBC has a corporate defined benefit pension plan and a lump-sum Defined benefit pension plans SMBC’s corporate defined benefit pension plan is a funded defined benefit pension plan, which is regulated by the Corporate Defined Benefit Pension Plan Law, one of the Japanese pension laws. Benefits are paid in exchange for services rendered by employees who worked for more than a specified period considering their years of service and the degree of their contribution to SMBC. SMBC’s pension fund is a special entity established in accordance with the pension laws, and SMBC has an obligation to make contributions to it. It has a board of directors which consists of an equal number of members elected from both the management and employees of SMBC. These board members have a fiduciary duty to administer and manage the pension fund. The objective of SMBC’s pension fund is to earn a return over the long term which is sufficient to pay future benefits to participants of the corporate defined benefit pension plan, including pension benefit plans, lump-sum The Corporate Defined Benefit Pension Plan Law requires a pension fund to review the assumptions and remeasure the required contribution at least every fifth fiscal year, in order to ensure that it maintains sufficient assets for future benefit payments. On the other hand, the present value of the defined benefit obligation is calculated annually based on actuarial valuations that are dependent upon a number of assumptions, including discount rates, mortality rates and future salary (benefit) increases, in accordance with IAS 19 “Employee Benefits.” Other types of defined benefit pension plans operated by the Group are generally established and operated in the same manner as described above. Lump-sum SMBC and some of the Company’s other subsidiaries have lump-sum lump-sum SMBC and a number of the Company’s other subsidiaries in Japan established retirement benefit trusts and contributed some of their marketable securities to these trusts in order to isolate these assets for retirement benefits by entering into contracts with trust banks. Retirement benefit trusts are voluntary funds that are used either to contribute assets to the pension funds or to directly settle retirement benefits. Among the Group, retirement benefit trusts are set up for the defined benefit pension plans, as well as for the lump-sum The assets belonging to the retirement benefit trusts are available to be used only to pay or fund retirement benefits, and practically held by an entity that is legally separated from the Group. Therefore, they are not available to the Group’s creditors even in bankruptcy and cannot be returned to the Group, unless either the remaining assets are sufficient to meet all the related obligations or the entities (funds) reimburse to the Group the retirement benefits which are already paid by the Group. Therefore, these assets are accounted for as plan assets. The following tables provide detailed information for the defined benefit plans. The amounts of the retirement benefit liabilities and the retirement benefit assets recognized in the consolidated statements of financial position at March 31, 2022 and 2021 were determined as follows: At March 31, 2022 2021 (In millions) Present value of unfunded obligations ¥ (32,948 ) ¥ (32,872 ) Present value of funded obligations (1,083,182 ) (1,114,185 ) Fair value of plan assets 1,642,554 1,627,110 Net retirement benefit assets (liabilities) before the asset ceiling ¥ 526,424 ¥ 480,053 Effect of the asset ceiling 17,928 — Net retirement benefit assets (liabilities) ¥ 508,496 ¥ 480,053 Of which retirement benefit liabilities included in “Other liabilities” ¥ (44,622 ) ¥ (38,881 ) Of which retirement benefit assets included in “Other assets” ¥ 553,118 ¥ 518,934 The movements in the defined benefit obligations for the fiscal years ended March 31, 2022 and 2021 were as follows: For the fiscal year ended 2022 2021 (In millions) At beginning of period ¥ 1,147,057 ¥ 1,188,097 Current service cost 30,658 32,099 Interest cost 7,077 6,352 Actuarial losses (gains)—demographic assumptions (689 ) 1,510 Actuarial losses (gains)—financial assumptions (30,384 ) (6,348 ) Actuarial losses (gains)—experience 10,780 2,630 Benefits paid (42,272 ) (41,933 ) Lump-sum (15,099 ) (12,463 ) Past service cost (1) 7,175 (28,023 ) Acquisition of subsidiaries and businesses — 46 Others 1,827 5,090 At end of period ¥ 1,116,130 ¥ 1,147,057 (1) During the fiscal year ended March 31, 2021, SMBC made an amendment to its terms of defined benefit pension plans. Primarily as a result of the amendment, the defined benefit obligation decreased by ¥28,023 million and a corresponding past service cost was recognized as profit for the fiscal year ended March 31, 2021. The movements in the fair value of plan assets for the fiscal years ended March 31, 2022 and 2021 were as follows: For the fiscal year ended 2022 2021 (In millions) At beginning of period ¥ 1,627,110 ¥ 1,318,073 Interest income 9,920 7,767 Return on plan assets excluding interest income 30,716 325,474 Contributions by employer 12,718 11,752 Benefits paid (42,272 ) (41,933 ) Others 4,362 5,977 At end of period ¥ 1,642,554 ¥ 1,627,110 The movements in the effect of the asset ceiling for the fiscal years ended March 31, 2022 and 2021 were as follows: For the fiscal year ended 2022 2021 (In millions) At beginning of period ¥ — ¥ — Change in the asset ceiling 17,928 — At end of period ¥ 17,928 ¥ — The amounts recognized in “General and administrative expenses” in the consolidated income statements for the fiscal years ended March 31, 2022, 2021 and 2020 were as follows: For the fiscal year ended March 31, 2022 2021 2020 (In millions) Current service cost ¥ 30,658 ¥ 32,099 ¥ 37,775 Net interest cost (2,843 ) (1,415 ) (1,254 ) Past service cost 7,175 (28,023 ) — Total ¥ 34,990 ¥ 2,661 ¥ 36,521 The plan assets at March 31, 2022 and 2021 were composed as follows: At March 31, 2022 2021 Quoted in Other Total Quoted in Other Total (In millions) Plan assets retained in the pension funds: Equity instruments ¥ 223,856 ¥ 134,300 ¥ 358,156 ¥ 248,064 ¥ 157,910 ¥ 405,974 Debt instruments 10,790 212,974 223,764 14,552 218,610 233,162 General account of life insurance companies 222 41,075 41,297 117 40,216 40,333 Other investments and short-term assets 38,051 402,958 441,009 48,178 295,104 343,282 Plan assets retained in the retirement benefit trusts: Equity instruments 488,762 2,357 491,119 530,485 2,211 532,696 Other short-term assets 78,318 8,891 87,209 63,324 8,339 71,663 Total ¥ 839,999 ¥ 802,555 ¥ 1,642,554 ¥ 904,720 ¥ 722,390 ¥ 1,627,110 The assets in the pension funds included common stocks issued by the Group at March 31, 2022 and 2021. The amounts of these stocks were not significant. The assets in retirement benefit trusts were primarily composed of Japanese equity instruments. Most of the plan assets held by the Group are invested in Japanese equity and debt instruments. Accordingly, the Group may be exposed to market risk arising from the domestic markets. The Group retained the voting rights of some of these equity instruments with fair values of ¥479,874 million and ¥515,890 million ( The principal actuarial assumptions used at March 31, 2022, 2021 and 2020 were as follows: At March 31, 2022 2021 2020 Discount rates 0.8 % 0.6 % 0.5 % Discount rates are weighted on the basis of the defined benefit obligations. The assumptions for future mortality are based on the official mortality table generally used for actuarial assumptions in Japan. The current average remaining life expectancy of an individual retiring at age 60 was 24 years for males and 29 years for females under the mortality table used at March 31, 2022 and 2021, and 23 years for males and 28 years for females under the mortality table used at March 31, 2020. The sensitivity analyses of the effect of changes in key assumptions on the defined benefit obligations at March 31, 2022 and 2021 were as follows: At March 31, 2022 2021 Increase/(decrease) Increase/(decrease) (In millions) Discount rates: Increase by 5 0 ¥ (61,869 ) ¥ (65,357 ) Decrease by 5 0 69,733 73,727 Average life expectancy at age 60: Increase of one year ¥ 34,064 ¥ 35,200 Each increase and decrease in the table above assumes that only one assumption is changed, with all other assumptions remaining unchanged. In practice, however, changes in multiple assumptions may occur in a mutually interrelated manner. The weighted average durations of defined benefit plans for the fiscal years ended March 31, 2022, 2021 and 2020 were as follows: At March 31, 2022 2021 2020 (Years) Lump-sum 12.7 12.9 10.5 Defined benefit pension plans 18.4 18.5 17.5 Funding Policy for Plan Assets The pension funds review the funding status of plan assets every year. If any funding deficit is identified, a measure to cover such deficit will be implemented, for example, by increasing the amount of contributions by the employer. Expected contribution Expected contributions to the defined benefit plans for the fiscal year ending March 31, 2023 are ¥14,478 million. Defined Contribution Plans SMBC and some of the Company’s other subsidiaries provide defined contribution plans. The amounts recognized as expenses for the defined contribution plans were ¥11,997 million, ¥10,994 million and ¥11,139 million for the fiscal years ended March 31, 2022, 2021 and 2020, respectively, which were included in “General and administrative expenses” in the consolidated income statements. Employees’ Pension Insurance Plan In Japan, the Government of Japan operates the Employees’ Pension Insurance Plan which covers most of the private entities’ employees. The amounts of contributions charged to expense for the Employees’ Pension Insurance Plan were ¥39,263 million, ¥37,692 million and ¥37,990 million for the fiscal years ended March 31, 2022, 2021 and 2020, respectively, which were included in “General and administrative expenses” in the consolidated income statements.

All issued shares are fully paid. The details of the stock options and the restricted shares outstanding are described in Note 40 “Share-Based Payment.” On May 15, 2019, the Company’s board of directors resolved to repurchase shares of its common stock and cancel all the repurchased shares. The resolution authorized the repurchase of up to the lesser of (i) an aggregate of 32,000,000 shares of its common stock and (ii) an aggregate of ¥100 billion between May 16, 2019 and August 30, 2019. On August 9, 2019, the Company completed the repurchase, acquiring 26,502,400 shares of its common stock for ¥100 billion in aggregate. The Company cancelled all of the repurchased shares on September 20, 2019. On November 12, 2021, the Company’s board of directors resolved to repurchase shares of its common stock and cancel all the repurchased shares. The resolution authorized the repurchase of up to the lesser of (i) an aggregate of 33,000,000 shares of its common stock and (ii) an aggregate of ¥100 billion between November 15, 2021 and November 11, 2022. The cancellation of the repurchased shares is scheduled on December 20, 2022. Preferred Stock The following table shows the number of shares of preferred stock at March 31, 2022 and 2021. At March 31, 2022 At March 31, 2021 Authorized Issued Authorized Issued Type 5 preferred stock 167,000 — 167,000 — Type 7 preferred stock 167,000 — 167,000 — Type 8 preferred stock 115,000 — 115,000 — Type 9 preferred stock 115,000 — 115,000 — All the preferred stocks have no stated value. There was no movement in preferred stock during the fiscal years ended March 31, 2022, 2021 and 2020. Capital stock, Capital surplus and Treasury stock “Capital stock” represents share capital under the Companies Act of Japan (“Companies Act”) adjusted by the amount corresponding to the preferred stock which is accounted for as a liability under IFRS. Purchases of treasury stock are recognized at cost in “Treasury stock.” Any additional paid-in Restriction on the Payment of Dividends The amount of the capital surplus and retained earnings of the Company that can be paid out as dividends is subject to restrictions under the Companies Act. These amounts are calculated based on the Company’s nonconsolidated statement of financial position prepared in accordance with Japanese GAAP. Therefore, the adjustments made to prepare the IFRS consolidated financial statements have no impact on the calculation. The total amount that the Company can pay out as a dividend was ¥2,199 billion at March 31, 2022. Other than the restriction by the Companies Act, the Company is required to maintain a risk-weighted capital ratio as per the Banking Act of Japan (“Banking Act”). The detail of the restriction is described in Note 46 “Financial Risk Management.” Therefore, the Company would not be able to pay a dividend if the ratio were to fall below the minimum amount as a result of the payment of the dividends. Since the Company is a holding company, its earnings rely mostly on dividend income from SMBC, and the Company’s other subsidiaries and associates. SMBC is subject to some restrictions on its dividend payment by the Companies Act and the Banking Act, similar to those applied to the Company’s. Other Reserves Remeasurements of defined benefit plans reserve Remeasurements of the defined benefit plans reserve includes the accumulated actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions, and return on plan assets excluding interest income.

The accumulated gains and losses related to equity instruments measured at FVOCI are transferred to retained earnings when the assets are derecognized. In addition, when the decline in the fair value of an equity instrument measured at FVOCI is above the threshold to qualify for a tax deduction, the accumulated losses related to the equity instrument are transferred to retained earnings.

Transfers of Financial Assets	38 TRANSFERS OF FINANCIAL ASSETS In the normal course of business, the Group transfers financial assets mainly through repurchase agreements, securities lending transactions and securitizations. Depending on the nature of the transactions, the transfers may either result in financial assets being derecognized or continuing to be recognized on the consolidated statements of financial position. Full derecognition occurs when the Group transfers its contractual rights to receive cash flows from financial assets, or retains the contractual rights to receive the cash flows, but assumes a contractual obligation to pay the cash flows to another party, and transfers substantially all the risks and rewards of ownership, including credit risk, prepayment risk and interest rate risk. Derecognition does not occur when the Group retains substantially all the risks and rewards of ownership of the financial assets, where the contractual rights to receive cash flows from the financial assets are transferred, or the rights are retained but obligations to pay the cash flows are assumed. The following tables show the carrying amounts and fair values of transferred financial assets that did not qualify for derecognition and their associated financial liabilities at March 31, 2022 and 2021: At March 31, 2022 Repurchase Loans and advances Residential Corporate (In millions) Carrying amount of assets ¥ 13,217,653 ¥ 1,517,316 ¥ 874,174 Carrying amount of associated liabilities 10,842,730 1,196,264 807,532 For those liabilities that have recourse only Fair value of assets ¥ — ¥ 1,696,689 ¥ 877,258 Fair value of associated liabilities — 1,241,195 807,532 Net position ¥ — ¥ 455,494 ¥ 69,726 At March 31, 2021 Repurchase Loans and advances Residential Corporate (In millions) Carrying amount of assets ¥ 9,837,768 ¥ 1,522,945 ¥ 849,842 Carrying amount of associated liabilities 8,561,981 1,207,662 788,300 For those liabilities that have recourse only Fair value of assets ¥ — ¥ 1,720,956 ¥ 855,254 Fair value of associated liabilities — 1,263,296 788,300 Net position ¥ — ¥ 457,660 ¥ 66,954 Repurchase Agreements and Securities Lending Transactions The Group lends or sells securities under agreements to repurchase them at a predetermined price on a future date. Since substantially all the risks and rewards of ownership of the securities are retained by the Group, the securities remain on the consolidated statements of financial position and their associated financial liabilities are recorded. The recourse of the counterparties to their associated financial liabilities is not limited to the underlying securities. Loans and Advances The Group transfers its loans and advances, including residential mortgages and corporate loans, mainly to bankruptcy-remote structured entities for securitizations whereby the structured entities issue debt securities to the Group for subordinated tranches and to investors for senior tranches. The investors have only recourse to the underlying financial assets due to their bankruptcy-remoteness. Since the Group retains substantially all the risks and rewards of ownership, the transferred financial assets do not qualify for derecognition. The Group therefore continues to recognize these transferred financial assets as loans and advances, and recognizes their associated financial liabilities arising from issuing debt securities to investors on the consolidated statements of financial position.

Share-based Payment	40 SHARE-BASED PAYMENT Stock Option Plans SMFG had introduced compensation-type stock options to directors, corporate auditors, and executive officers of SMFG and SMBC (“SMFG Stock Acquisition Rights”), which served as an incentive for them to further contribute to the equity appreciation and achieve better corporate performance through sharing the benefits and risks of the share price performance with the shareholders. The following table provides an overview of the significant terms and conditions of the stock option plan. Title of grantees Exercise period Requisite service period Method of settlement SMFG Stock Acquisition Rights Directors, corporate auditors and executive officers of SMFG and SMBC Not exceeding 30 years from the date of allocation of stock acquisition rights (1) One year from the date of the ordinary general meeting of shareholders of SMFG to the closing of the next ordinary general meeting of shareholders of SMFG Common stock of SMFG (1) A stock acquisition rights holder can exercise the rights from the day they are relieved of their positions either as a director, a corporate auditor or an executive officer (“Start of Exercise Date”) to 20 years from the Start of Exercise Date. The number and the weighted average exercise prices of stock options for the fiscal years ended March 31, 2022 and 2021 were as follows: For the fiscal year ended March 31, 2022 2021 Number of (1) Weighted Number of (1) Weighted Outstanding at beginning of period 634,700 ¥ 1 722,500 ¥ 1 Exercised (96,800 ) 1 (87,800 ) 1 Outstanding at end of period 537,900 ¥ 1 634,700 ¥ 1 Exercisable at end of period 332,200 ¥ 1 346,700 ¥ 1 (1) Number of options is the number of SMFG’s common stock granted by the exercise of stock options. In June 2017, SMFG and SMBC resolved to discontinue the issuance of new stock options. Thereafter, SMFG has not issued any new stock options. The weighted average stock price at the date of exercise was ¥3,886 and ¥2,903 for the fiscal years ended March 31, 2022 and 2021, respectively. Summarized information about stock options outstanding at March 31, 2022 and 2021 was as follows: At March 31, 2022 2021 Exercise Number of Remaining Number of Remaining SMFG Stock Acquisition Rights ¥ 1 537,900 21.3 634,700 22.4 Compensation Plans Utilizing Restricted Stock In July 2017, the SMFG compensation committee resolved to revise the executive compensation policy and to introduce new stock compensation plans that utilize restricted stock. The plans consist of Stock Compensation Plan I (“Plan I”), which determines remuneration primarily based on the medium-term performance, Stock Compensation Plan II (“Plan II”), which determines remuneration primarily based on the annual performance and Stock Compensation Plan III (“Plan III”), which determines remuneration primarily based on corporate title. Plan I (medium-term performance share plan) has an evaluation period of three years, corresponding with SMFG’s medium-term management plan. Executives are initially allotted shares of restricted stock equivalent to the monetary amount determined based on the executive’s corporate title. After the completion of the evaluation period, the compensation committee reviews the progress of the medium-term management plan, performance of SMFG’s common stock, and results of customer satisfaction surveys, qualitative indicators related to environment, social, and governance (“ESG”) initiatives and other factors, to determine the final amount to be released from transfer restrictions. In case the final amount falls below the initial amount, SMFG retrieves all or part of the allotted shares at no cost. Under Plan II (annual performance share plan), executives are allotted shares of restricted stock equivalent to a certain portion of the monetary amount determined based on the annual performance of SMFG and SMBC, as well as on the individual performance of the executives reviewed both from short-term and medium-to-long-term Under Plan III (promotion reward plan), executives are allotted shares of restricted stock equivalent to pre-determined The eligible executives for the plans are directors (excluding outside directors), corporate executive officers and executive officers, etc. of SMFG, directors (excluding outside directors) and executive officers, etc. of SMBC and representative corporate executive officers of certain of the Company’s subsidiaries. As part of the executive compensation policy, SMFG and SMBC introduced provisions for forfeiture and claw-back of vested stock under the plans in order to restrain excessive risk-taking and foster a prudent risk culture expected of a financial institution. The number of restricted shares and the fair value of restricted shares at the measurement date for the fiscal years ended March 31, 2022 and 2021 were as follows: For the fiscal year ended 2022 2021 Outstanding at beginning of period 1,266,013 923,425 Allotted 322,041 868,505 Released (179,557 ) (486,964 ) Forfeited (8,817 ) (38,953 ) Outstanding at end of period 1,399,680 1,266,013 Fair value at measurement date ¥ 3,749 ¥ 3,015 The fair value of restricted shares is based on the market price of SMFG common stock. If any granted conditions exist, the terms and conditions upon which the shares were granted, are taken into account when estimating both the number of shares expected to vest and the fair value of the shares granted. The amount of restricted shares recognized as expenses was measured based on the fair value of the restricted shares granted, which were ¥1,296 million and ¥927 million for the fiscal years ended March 31, 2022 and 2021, respectively, and included in “General and administrative expenses” in the consolidated income statements.

The Group does not expect that the outcome of these proceedings will have a significant adverse effect on the consolidated financial statements of the Group. The Group has recorded adequate provisions with respect to litigation arising out of normal business operations. The Group has not disclosed any contingent liability associated with these legal actions because it cannot reliably be estimated. In addition, the Group’s wholly-owned broker-dealer subsidiary, SMBC Nikko Securities Inc (“SMBC Nikko Securities”), is involved in ongoing legal proceedings in Japan. On March 24 and April 13, 2022, the Tokyo District Public Prosecutors Office brought charges against SMBC Nikko Securities and several of its former and current officers and employees, on allegations of illegal stabilization transactions in violation of the Financial Instruments and Exchange Act of Japan (“FIEA”). A criminal proceeding is ongoing before the Tokyo District Court, which could result in monetary penalties for SMBC Nikko Securities as an entity, although the expected duration and outcome of the proceedings are uncertain. Capital Commitments At March 31, 2022 and 2021, the Group had ¥6,587 million and ¥8,532 million, respectively, of contractual commitments to acquire property, plant and equipment. The Group’s management is confident that future net revenues and funding will be sufficient to cover these commitments. Loan Commitments and Financial Guarantees and Other Credit-related Contingent Liabilities Loan commitment contracts on overdrafts and loans are agreements to lend up to a prescribed amount to customers, as long as there is no violation of any condition established in the contracts. However, since many of these loan commitments are expected to expire without being drawn down, the total amount of unused commitments does not necessarily represent an actual future cash flow requirement. Many of these loan commitments include clauses under which the Group can reject an application from customers or reduce the contract amounts in cases where economic conditions change, the Group needs to secure claims, or some other significant event occurs. Financial guarantees are contracts that require the issuer to make specified payments to reimburse the holder for a loss it incurs because a specified debtor fails to make payments when due in accordance with the terms of the debt instrument. Other credit-related contingent liabilities include performance bonds, which are contracts that provide compensation if another party fails to perform the contractual obligation. The table below shows the nominal amounts of undrawn loan commitments, and financial guarantees and other credit-related contingent liabilities at March 31, 2022 and 2021. At March 31, 2022 2021 (In millions) Loan commitments ¥ 73,246,384 ¥ 71,677,806 Financial guarantees and other credit-related contingent liabilities 11,722,240 9,872,696 Total ¥ 84,968,624 ¥ 81,550,502

Analysis of Financial Assets and Liabilities by Measurement Basis	43 ANALYSIS OF FINANCIAL ASSETS AND LIABILITIES BY MEASUREMENT BASIS After initial recognition, financial assets and liabilities are measured either at fair value or amortized cost, within the measurement categories as defined in IFRS 9. The summary of significant accounting policies in Note 2 describes how these categories of financial assets and liabilities are measured, and how income and expenses are recognized either in profit or loss, or in other comprehensive income. The following tables present the carrying amounts of the financial assets and liabilities, by category and by line item, of the consolidated statements of financial position. At March 31, 2022 Financial assets and Financial assets and Debt instruments at Equity instruments at Total (In millions) Financial assets: Cash and deposits with banks ¥ — ¥ 75,697,521 ¥ — ¥ — ¥ 75,697,521 Call loans and bills bought — 1,965,135 — — 1,965,135 Reverse repurchase agreements and cash collateral on securities borrowed — 11,303,930 — — 11,303,930 Trading assets 3,736,296 — — — 3,736,296 Derivative financial instruments 6,443,748 — — — 6,443,748 Financial assets at fair value through profit or loss 1,695,585 — — — 1,695,585 Investment securities — 83,954 28,066,966 4,598,485 32,749,405 Loans and advances — 104,635,815 — — 104,635,815 Other financial assets (1) — 5,309,839 — — 5,309,839 Total ¥ 11,875,629 ¥ 198,996,194 ¥ 28,066,966 ¥ 4,598,485 ¥ 243,537,274 Financial liabilities: Deposits (2) ¥ (8,569 ) ¥ 162,602,061 ¥ — ¥ — ¥ 162,593,492 Call money and bills sold — 1,130,000 — — 1,130,000 Repurchase agreements and cash collateral on securities lent — 20,113,162 — — 20,113,162 Trading liabilities 3,181,992 — — — 3,181,992 Derivative financial instruments 6,966,336 — — — 6,966,336 Financial liabilities designated at fair value through profit or loss 455,734 — — — 455,734 Borrowings (2) (138 ) 20,584,789 — — 20,584,651 Debt securities in issue (2) 5,721 11,422,716 — — 11,428,437 Other financial liabilities (1) 851 7,808,826 — — 7,809,677 Total ¥ 10,601,927 ¥ 223,661,554 ¥ — ¥ — ¥ 234,263,481 At March 31, 2021 Financial assets and Financial assets and Debt instruments at Equity instruments at Total (In millions) Financial assets: Cash and deposits with banks ¥ — ¥ 73,090,816 ¥ — ¥ — ¥ 73,090,816 Call loans and bills bought — 2,553,468 — — 2,553,468 Reverse repurchase agreements and cash collateral on securities borrowed — 11,738,072 — — 11,738,072 Trading assets 3,140,736 — — — 3,140,736 Derivative financial instruments 5,521,617 — — — 5,521,617 Financial assets at fair value through profit or loss 1,744,848 — — — 1,744,848 Investment securities — 72,015 26,392,635 4,586,811 31,051,461 Loans and advances — 97,714,938 — — 97,714,938 Other financial assets (1) — 4,250,454 — — 4,250,454 Total ¥ 10,407,201 ¥ 189,419,763 ¥ 26,392,635 ¥ 4,586,811 ¥ 230,806,410 Financial liabilities: Deposits (2) ¥ (2,004 ) ¥ 155,495,658 ¥ — ¥ — ¥ 155,493,654 Call money and bills sold — 1,368,515 — — 1,368,515 Repurchase agreements and cash collateral on securities lent — 18,509,906 — — 18,509,906 Trading liabilities 2,080,826 — — — 2,080,826 Derivative financial instruments 4,949,433 — — — 4,949,433 Financial liabilities designated at fair value through profit or loss 239,519 — — — 239,519 Borrowings (2) 514 19,422,841 — — 19,423,355 Debt securities in issue (2) 9,596 11,219,004 — — 11,228,600 Other financial liabilities (1) 1,045 8,416,003 — — 8,417,048 Total ¥ 7,278,929 ¥ 214,431,927 ¥ — ¥ — ¥ 221,710,856 (1) Other financial assets and liabilities comprise of those included in other assets and liabilities, which meet the definition of a financial asset and liability.

Fair Value of Financial Assets

Fair Value of Financial Assets and Liabilities	12 Months Ended

Text block [abstract]
Fair Value of Financial Assets and Liabilities	44 FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair values stated below represent the best estimates based on a range of methods and assumptions. In determining the fair value of financial assets and liabilities, the Group gives the highest priority to a quoted market price in an active market. If such prices are not available, it establishes fair value using valuation techniques. The valuation techniques, if used, make maximum use of observable inputs, and rely as little as possible on unobservable inputs. Financial Assets and Liabilities Carried at Fair Value Valuation Process The Group undertakes a valuation process based on its valuation control framework, which governs internal control standards, methodologies and procedures to ensure that the fair values are determined or validated independently of the front office. The Group uses valuation techniques commonly used by market participants to price the financial instruments and they have been demonstrated to provide reliable estimates of prices obtained in actual market transactions. The valuation techniques include the DCF method, option pricing models and reference to the current fair value of another instrument that is substantially the same. Key adjustments, such as liquidity risk and credit risk adjustments are also taken into account to derive fair values. Where valuation techniques are used to determine fair values, they are validated and reviewed. In principal subsidiaries, their risk management departments, which are independent from the business units, review significant valuation methodologies at least once a year, and recalibrate model parameters and inputs by comparing fair values derived from the valuation techniques to the external market data such as broker quotes. Where the data obtained from third-party sources such as brokers and pricing service providers are utilized in determining fair values, those departments also examine those data, taking into account the consistency among the different sources, the aging of the data and other factors. In addition, accounting departments in those principal subsidiaries are responsible for ensuring that the accounting policies and procedures to determine fair values are in compliance with relevant accounting standards. Fair Value Hierarchy Financial assets and liabilities measured at fair value are classified into one of three levels within a fair value hierarchy based on the inputs used in the fair value measurement. The three levels of the fair value hierarchy are as follows: • quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity can access at the measurement date (Level 1); • inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly (Level 2); and • significant unobservable inputs for the asset or liability (Level 3). The following tables present the carrying amounts of financial assets and liabilities carried at fair value based on the three levels of the fair value hierarchy at March 31, 2022 and 2021. At March 31, 2022 Level 1 (1) Level 2 (1) Level 3 Total (In millions) Financial assets: Trading assets: Debt instruments ¥ 2,860,215 ¥ 629,043 ¥ — ¥ 3,489,258 Equity instruments 245,186 1,852 — 247,038 Total trading assets 3,105,401 630,895 — 3,736,296 Derivative financial instruments: Interest rate derivatives 612,246 2,981,691 6 3,593,943 Currency derivatives 101 2,697,933 5,951 2,703,985 Equity derivatives 74,820 689 26,804 102,313 Commodity derivatives 1,413 20,127 — 21,540 Credit derivatives — 21,318 649 21,967 Total derivative financial instruments 688,580 5,721,758 33,410 6,443,748 Financial assets at fair value through profit or loss: Debt instruments 516,455 447,738 693,013 1,657,206 Equity instruments 2,375 120 35,884 38,379 Total financial assets at fair value through profit or loss 518,830 447,858 728,897 1,695,585 Investment securities at fair value through other comprehensive income: Japanese government bonds 15,774,197 — — 15,774,197 U.S. Treasury and other U.S. government agency bonds 5,681,789 — — 5,681,789 Other debt instruments 1,378,880 5,232,100 — 6,610,980 Total debt instruments 22,834,866 5,232,100 — 28,066,966 Equity instruments 4,117,832 11,940 468,713 4,598,485 Total investment securities at fair value through other comprehensive 26,952,698 5,244,040 468,713 32,665,451 Total ¥ 31,265,509 ¥ 12,044,551 ¥ 1,231,020 ¥ 44,541,080 Financial liabilities: Trading liabilities: Debt instruments ¥ 3,026,965 ¥ 125,078 ¥ — ¥ 3,152,043 Equity instruments 23,339 6,610 — 29,949 Total trading liabilities 3,050,304 131,688 — 3,181,992 Derivative financial instruments: Interest rate derivatives 218,193 3,547,303 7,168 3,772,664 Currency derivatives 204 2,983,028 4,299 2,987,531 Equity derivatives 145,021 2,676 11,420 159,117 Commodity derivatives 202 19,342 — 19,544 Credit derivatives — 27,352 128 27,480 Total derivative financial instruments 363,620 6,579,701 23,015 6,966,336 Financial liabilities designated at fair value through profit or loss — 164,648 291,086 455,734 Others (2)(3) — 917 (3,052 ) (2,135 ) Total ¥ 3,413,924 ¥ 6,876,954 ¥ 311,049 ¥ 10,601,927 At March 31, 2021 Level 1 (1) Level 2 (1) Level 3 Total (In millions) Financial assets: Trading assets: Debt instruments ¥ 2,121,065 ¥ 611,415 ¥ — ¥ 2,732,480 Equity instruments 403,556 4,700 — 408,256 Total trading assets 2,524,621 616,115 — 3,140,736 Derivative financial instruments: Interest rate derivatives 47,289 3,049,703 289 3,097,281 Currency derivatives 104 2,325,254 507 2,325,865 Equity derivatives 48,283 2,908 15,411 66,602 Commodity derivatives 1,043 6,267 — 7,310 Credit derivatives — 22,702 1,857 24,559 Total derivative financial instruments 96,719 5,406,834 18,064 5,521,617 Financial assets at fair value through profit or loss: Debt instruments 486,073 619,641 561,450 1,667,164 Equity instruments 44,836 71 32,777 77,684 Total financial assets at fair value through profit or loss 530,909 619,712 594,227 1,744,848 Investment securities at fair value through other comprehensive income: Japanese government bonds 14,293,611 — — 14,293,611 U.S. Treasury and other U.S. government agency bonds 5,564,944 — — 5,564,944 Other debt instruments 1,007,148 5,526,932 — 6,534,080 Total debt instruments 20,865,703 5,526,932 — 26,392,635 Equity instruments 4,123,247 15,959 447,605 4,586,811 Total investment securities at fair value through other comprehensive income 24,988,950 5,542,891 447,605 30,979,446 Total ¥ 28,141,199 ¥ 12,185,552 ¥ 1,059,896 ¥ 41,386,647 Financial liabilities: Trading liabilities: Debt instruments ¥ 1,951,218 ¥ 51,373 ¥ — ¥ 2,002,591 Equity instruments 59,887 18,348 — 78,235 Total trading liabilities 2,011,105 69,721 — 2,080,826 Derivative financial instruments: Interest rate derivatives 22,165 2,623,917 3,877 2,649,959 Currency derivatives 10 2,169,202 5,848 2,175,060 Equity derivatives 79,008 3,211 8,279 90,498 Commodity derivatives 510 4,861 — 5,371 Credit derivatives — 28,454 91 28,545 Total derivative financial instruments 101,693 4,829,645 18,095 4,949,433 Financial liabilities designated at fair value through profit or loss — 72,623 166,896 239,519 Others (2)(3) — 8,047 1,104 9,151 Total ¥ 2,112,798 ¥ 4,980,036 ¥ 186,095 ¥ 7,278,929 (1) Transfers between levels of the fair value hierarchy are deemed to have occurred at the beginning of the period.

(2) Transfers between levels of the fair value hierarchy are deemed to have occurred at the beginning of the period. For the fiscal year ended March 31, 2022 , primarily due to an increase in observability of certain financial liabilities designated at fair value through profit or loss. On the other hand, for the fiscal year ended March 31, 2021, those amounted to ¥27,377 million primarily due to an increase in observability of certain investment funds. (3) Derivatives embedded in financial liabilities, except for financial liabilities designated at fair value through profit or loss, are separately accounted for, but presented together with the host contract in the consolidated statements of financial position. In these tables, the separated embedded derivatives whose host contracts are carried at amortized cost are presented within others. Although the separated embedded derivatives may have a positive or a negative fair value, they have been presented in these tables as liabilities to be consistent with the host contract. The following table presents total gains or losses included in profit or loss for the Level 3 financial assets and liabilities, and changes in unrealized gains or losses included in profit or loss related to those financial assets and liabilities held at March 31, 2022 and 2021 by line item of the consolidated income statements.

The difference between the transaction price and the fair value that would be determined at initial recognition using a valuation technique is referred to as “day one profit and loss,” which is not recognized immediately in the consolidated income statements. The table above shows the day one profit and loss balances, all of which are derived from derivative financial instruments, financial assets at fair value through profit or loss and financial liabilities designated at fair value through profit or loss. The release to profit or loss results from the realization due to redemption or sales, and the amortization of the deferred day one profit and loss with the passage of time over the life of the instruments. Valuation Techniques Financial instruments which are classified as trading assets and liabilities, derivative financial instruments, financial assets at fair value through profit or loss, investment securities at fair value through other comprehensive income and financial liabilities designated at fair value through profit or loss are measured at fair value in the consolidated statements of financial position. These instruments are measured at fair value using a quoted market price, if they are traded in an active market, or, for others, using the fair value measurement techniques as discussed below. Trading assets and trading liabilities Debt and equity instruments traded in an active market are measured at fair value using a quoted market price in such a market and they are categorized within Level 1. If a quoted market price is not available, they are measured by using a price quoted by a third party, such as a pricing service or broker, or by reference to the current fair value of another instrument that is substantially the same, based on inputs such as prices obtained from brokers, observable interest rates and spreads. These financial instruments are categorized within Level 2. Debt instruments measured at fair value using the DCF method, where primary inputs are observable interest rates and credit spreads, inferred from the prevailing market rates, are also categorized within Level 2. Derivative financial instruments (including embedded derivatives) Listed derivatives (including interest rates, bonds, currencies, stocks and commodities) are measured at fair value using the settlement price announced by the major exchange on which transactions are traded because the settlement price in the exchange reflects the most current transaction price, and is readily and regularly available from the exchange. Listed derivatives are categorized within Level 1. OTC derivatives (non-exchange-traded are not directly observable in the market, including historical correlation coefficients, historical volatilities and prepayment rates. If the impact of these unobservable inputs is significant to the fair value for those transactions, the Group categorizes the transactions within Level 3. The credit loss protection scheme which the Group offered to Goldman Sachs (“GS”) was considered to be a credit derivative, where the underlying reference entities were the American and European corporate entities covered in the commitment line portfolio of the GS group. The fair value of this derivative was determined using an ordinary collateralized debt obligation (“CDO”) pricing model, commonly used in the financial markets. The Group took some portions of the positions in subordinated and mezzanine tranches, which covered the first and second credit losses from the portfolio. The major inputs for this derivative were credit default swap (“CDS”) spread rates, correlation ratios of CDS indices for similar portfolios, and the expected additional commitment withdrawal ratio. Although CDS spread rates and correlation ratios were observable in an active market or available from brokers, this whole scheme was categorized within Level 3 as the expected additional withdrawal ratio, which was considered to be a significant input, was not observable in the market. Furthermore, this scheme was terminated in December 2021. In addition, the fair value of OTC derivatives incorporates both counterparty credit risk in relation to OTC derivative assets and own credit risk in relation to OTC derivative liabilities. The Group calculates the credit risk adjustments by applying the probability of default that reflects the counterparty’s or its own credit risk to the OTC derivative exposures and multiplying the result by the loss expected in the event of default. For the probability of default, the Group uses observable market data, where possible. The fair value of OTC derivatives also incorporates adjustments reflecting funding costs to uncollateralized components of these derivatives, based on market-observable spreads on the Group’s funding transactions. The OTC derivative exposures used are determined taking into consideration the effect of master netting agreements and collateral. As the Group manages the OTC derivatives on the basis of its net credit risk exposure, the credit risk adjustments of those OTC derivatives are measured on a portfolio basis in accordance with the exception set forth in IFRS 13. Financial assets at fair value through profit or loss Non-trading Publicly traded stocks, investment trusts and funds are measured at fair value using the market price and are categorized within Level 1 if they are traded in an active market. Instruments whose prices are not available in the market, such as privately offered investment trusts, are measured at fair value based on the unit price, which is usually regarded as an exit price, obtained from the fund administrator or investment management firm. In such a case, these investment trusts and funds are categorized within Level 2. Other investment funds included in financial assets at fair value through profit or loss, such as private equity funds and real estate investment funds, are generally measured at fair value based on net asset value, which includes significant unobservable inputs. These funds are categorized within Level 3. Certain loans and advances are measured at fair value using discounted cash flow models taking into account certain factors including counterparties’ credit ratings, pledged collateral and market interest rates, which include significant unobservable inputs, and are categorized within Level 3. Some equity and debt instruments in this category are hybrid instruments which have both equity and debt features. These include preferred stocks which are measured at fair value using the Monte Carlo Simulation valuation model, if they are indexed to the market prices in a stock exchange. The valuation model uses the historical volatility of the listed stocks as an input, which are not observable in the market, resulting in these instruments being categorized within Level 3. Other types of preferred stocks and other non-hybrid instruments are evaluated using valuation techniques for unlisted stocks, which are normally used for private equity investments. The Group calculates the fair values of these instruments based on the market approach using market multiples or others in which significant unobservable inputs are used. These instruments are categorized within Level 3. Investment securities at fair value through other comprehensive income Debt instruments are measured at fair value using a quoted market price and categorized within Level 1 if they are traded in an active market. Debt instruments are categorized within Level 2 if they are measured at fair value using a price quoted by a third party, such as a pricing service or broker, or by reference to the current fair value of another bond that is substantially the same based on inputs such as prices obtained from brokers, observable interest rates and spreads. As for equity instruments, listed stocks are measured at fair value based on the market price at a stock exchange and categorized within Level 1 if they are traded in an active market. Unlisted common and preferred stocks in this category are measured at fair value based on the market approach using market multiples or others in which significant unobservable inputs are used. These instruments are categorized within Level 3. Financial liabilities designated at fair value through profit or loss Certain financial liabilities containing embedded derivatives are measured at fair value using valuation techniques. The host contracts of those liabilities are measured at fair value based on the present values of the contractual cash flows for expected remaining maturities, using the relevant credit-adjusted rates based on observable market data on the Group’s funding transactions. The embedded derivatives, which forms part of the contractual cash flows, are measured at fair value by using the same procedures as described in “Derivative financial instruments (including embedded derivatives).” Those financial liabilities are measured at fair value by combining the fair values of the host contracts and embedded derivatives. The valuation techniques for most of those liabilities use inputs which are not directly observable in the market, including historical correlation coefficients and historical volatilities. If the impact of these unobservable inputs is significant to the fair value for those liabilities, the Group categorizes those liabilities within Level 3. Significant Unobservable Inputs The following tables present quantitative information about significant unobservable inputs used in the fair value measurement for Level 3 financial assets and liabilities at March 31, 2022 and 2021. At March 31, 2022 Assets Liabilities Valuation (1) Significant unobservable inputs (1) Range of (1) (In millions) Derivative financial instruments: Interest rate derivatives ¥ 6 ¥ 7,168 Option model Interest rate to interest rate correlation 16%-99% Quanto correlation 7%-30% Currency derivatives 5,951 4,299 Option model Interest rate to interest rate correlation 29%-99% Quanto correlation 7%-49% Foreign exchange volatility 11%-39% DCF model Prepayment rate 22 % Equity derivatives 26,804 11,420 Option model Equity to equity correlation 45%-92% Quanto correlation (16 )%- Equity volatility 17%-79% Credit derivative s 649 128 Credit Default model Quanto correlation 15%-25% Financial assets at fair value through profit or loss: Debt instruments 693,013 — Monte Carlo Simulation Equity volatility 17%-38% Option model Foreign exchange volatility 12%-41% DCF model Probability of default rate 0%-23% Loss given default rate 10%-100% Net asset value (2) — — Equity instruments 35,884 — DCF model Probability of default rate 0%-2% Loss given default rate 90% See note (3) below — — Investment securities at fair value through other comprehensive income: Equity instruments 468,713 — Market multiples Price/Earnings multiple 9.3x-48.5x Price/Book value multiple 0.3x-2.2x EV/EBITDA multiple 5.8x-15.5x Liquidity discount 20% See note (3) below — — Financial liabilities designated at fair value through — 291,086 Option model Equity to equity correlation 43%-93% Interest rate to interest rate correlation 29%-30% Quanto correlation (16 )%- Equity volatility 13%-57% Credit Default model Quanto correlation 15%-25% Others (4) — (3,052 ) Option model Equity to equity correlation 57%-93% Interest rate to interest rate correlation 16%-99% Quanto correlation 7%-49% Equity volatility 17%-49% Foreign exchange volatility 12%-41% Credit Default model Quanto correlation 15%-90% At March 31, 2021 Assets Liabilities Valuation (1) Significant unobservable inputs (1) Range of (1) (In millions) Derivative financial instruments: Interest rate derivatives ¥ 289 ¥ 3,877 Option model Interest rate to interest rate correlation 15%-98% Quanto correlation 8%-30% Currency derivatives 507 5,848 Option model Interest rate to interest rate correlation 27%-98% Quanto correlation 7%-48% Foreign exchange volatility 7%-31% Equity derivatives 15,411 8,279 Option model Equity to equity correlation 36%-97% Quanto correlation (33)%-35% Equity volatility 17%-61% Credit derivatives 1,857 91 CDO pricing model Additional withdrawal ratio 45% Credit Default model Quanto correlation 15%-90% Financial assets at fair value through profit or loss: Debt instruments 561,450 — Monte Carlo Simulation Equity volatility 26%-41% Option model Foreign exchange volatility 9%-32% DCF model Probability of default rate 0%-12% Loss given default rate 10%-100% Net asset value (2) — — Equity instruments 32,777 — DCF model Probability of default rate 0%-2% Loss given default rate 90% See note (3) below — — Investment securities at fair value through other comprehensive income: Equity instruments 447,605 — Market multiples Price/Earnings multiple 9.4x-63.6x Price/Book value multiple 0.2x-2.9x EV/EBITDA multiple 3.1x-14.8x Liquidity discount 20% See note (3) below — — Financial liabilities designated at fair value through profit or loss — 166,896 Option model Equity to equity correlation 36%-93% Interest rate to interest rate correlation 27%-98% Quanto correlation (33)%-48% Equity volatility 17%-50% Credit Default model Quanto correlation 15%-30% Others (4) — 1,104 Option model Equity to equity correlation 48%-97% Interest rate to interest rate correlation 15%-98% Quanto correlation (27)%-48% Equity volatility 17%-53% Foreign exchange volatility 9%-32% Credit Default model Quanto correlation 15%-90% (1) Valuation techniques and unobservable inputs for insignificant Level 3 financial assets and liabilities are excluded. (2) The Group has determined that the net asset value represents fair values of certain investment funds. (3) Fair values of certain equity instruments such as unlisted stocks are estimated on the basis of an analysis of the investee’s financial position and results, risk profile, prospects and other factors. A range of key inputs is not provided in these tables as it is not practical to do so given the nature of such valuation techniques. (4) Derivatives embedded in financial liabilities, except for financial liabilities designated at fair value through profit or loss, are separately accounted for, but presented together with the host contract in the consolidated statements of financial position. In these tables, the separated embedded derivatives whose host contracts are carried at amortized cost are presented within others. Although the separated embedded derivatives may have a positive or a negative fair value, they have been presented in these tables as liabilities to be consistent with the host contract. Correlation Correlation represents a measure of the relationship between the movements of two variables, which is expressed as a number between plus and minus one. A positive correlation indicates that two variables move in the same direction while a negative correlation indicates that they move in opposite directions. Correlations could be any combination of variables such as interest rates, foreign exchange rates, CDS spread and stock price movements. Thus, both same-asset correlation and cross-asset correlation are used. Interest rate correlation between two different tenors is an example of same-asset correlations while quanto correlation which is the correlation between foreign exchange rates and another variable is an example of cross-asset correlation. These correlations are used in the valuation techniques of complex derivatives and estimated based on historical data. In general, a significant increase in the correlation in isolation would result in either a significantly higher or lower fair value measurement, depending on the terms of the instruments. Volatility Volatility represents a measure of how much a particular instrument, parameter or index is expected to change in value over time. The volatilities used in the valuation of some type of derivative instruments with optionality refer to the potential change in price or level of the underlying interest rates, foreign exchange rates or equity instruments. The volatilities of underlying listed stocks are used in the valuation of preferred stocks containing optionality. These volatilities are estimated based on historical data or information provided by third-party sources, together with other analytical techniques. In general, a significant increase in the volatility in isolation would result in a significantly higher fair value measurement. Additional withdrawal ratio Additional withdrawal ratio represented the expected additional withdrawal ratio of unfunded commitment lines in the reference portfolio (mainly revolving credit facilities for commercial paper backup) concerning the credit loss protection scheme offered to GS. The expected additional withdrawal ratio was estimated based on historical data of actual funded amounts at default for similar portfolios. In general, a significant increase in the additional withdrawal ratio in isolation would have a significant unfavorable impact (i.e., an increase in derivative liabilities or a decrease in derivative assets) on the fair value measurement. Prepayment rates Prepayment rate represents the ratio of principal that is assumed to be paid prematurely in each period. Prepayment rates change the future cash flows. In general, a significant increase in the prepayment rate in isolation would result in a significantly lower or higher fair value measurement. Probability of default and loss given default rates Probability of default rate represents the probability of default that reflects the counterparty’s credit risk while loss given default rate represents the loss expected in the event of default. Those are estimated based on historical experiences. In general, a significant increase in probability of default rate or loss given default rate in isolation would result in a significantly lower fair value measurement. Price/Earnings, price/book value multiples Price/Earnings (“P/E”) multiple represents the ratio of the equity value to the net income, while price/book value (“P/B”) multiple represents the ratio of the equity value to the book value. These multiples are estimated based on comparable listed companies. In general, a signi

Financial Risk Management	46 FINANCIAL RISK MANAGEMENT The Group classifies risks into the following categories: credit risk, market risk, liquidity risk, operational risk and conduct risk. This note presents information about the Group’s exposure to credit risk, market risk, and liquidity risk, and its policies and processes for measuring and managing these risks. Risk Management System Based on the recognition of the importance of risk management, top management is actively involved in the risk management process, and systems are in place for verifying the effectiveness and appropriateness of this process. Specifically, the Group-wide basic policies for risk management are determined by the Management Committee before being authorized by the board of directors, and regular reports are issued to the board of directors by the Group Chief Risk Officer (“CRO”) with regard to the status of risk management based on these policies. Three lines of defense have been defined, and the Group has clarified related roles and responsibilities of relevant divisions. With these provisions in place, risk management systems have been established based on the characteristics of particular businesses, and measures are being put in place to strengthen and improve the effectiveness of these systems in accordance with these basic policies for risk management. Furthermore, the Group is strengthening Group-wide risk management systems through the Group CRO Committee and the Global CRO Committee. The diagram below represents the risk management system of the Group. Credit Risk Credit risk is the risk of incurring losses from decline or loss of the value of an asset (including off-balance off-balance Credit risk management system Credit risk is the most significant risk to which the Group is exposed. The purpose of credit risk management is to keep the credit risk exposure to a permissible level relative to capital, to maintain the quality of assets and to ensure returns commensurate with risk. At the Group, the Group CRO formulates credit risk management policies each year on the basis of Group-wide basic policies for risk management. The Credit & Investment Planning Department, responsible for the comprehensive management of credit risk, drafts and administers credit risk regulations including the Group credit policies, manages non-performing The following chart shows the credit risk management system of SMBC, the Group’s significant banking subsidiary. At SMBC, the Credit & Investment Planning Department within the Risk Management Unit is responsible for the comprehensive management of credit risk. This department drafts and administers credit policies, the internal rating system, credit authority guidelines, and credit application guidelines, and manages NPLs, including impaired loans, and other aspects of credit portfolio management. The department also cooperates with the Corporate Risk Management Department in quantifying credit risk (risk capital and risk-weighted assets) and controls SMBC’s entire credit risk. Further, the Credit Portfolio Management Department within the Credit & Investment Planning Department strives to stabilize the credit portfolio and manage the risk through credit derivatives, loan asset sales and other instruments. The credit departments, in cooperation with branches, conduct credit risk management for loans and manage portfolios. The credit limits they use are based on the baseline amounts that the Credit & Investment Planning Department establishes for each grading category, with particular attention paid to evaluating and managing customers or loans perceived to have particularly high credit risk. The Corporate Research Department engages in research on industries and analyzes the business and financial conditions of borrower enterprises to detect early signs of problems or growth potential. The Credit Administration Department is responsible for handling NPLs of borrowers classified as potentially bankrupt or lower, and formulates plans for workouts, including write-offs, and corporate rehabilitation. The department closely liaises with SMBC Servicer Co., Ltd., a Group company, which engages in related services to efficiently reduce the amount of NPLs, including through the sales of loans. The Internal Audit Unit of SMBC, operating independently of the business units, audits asset quality, accuracy of grading and state of credit risk management, and reports the results directly to the board of directors, the Management Committee and audit & supervisory committee. SMBC has established the Credit Risk Committee to undertake control of credit risk and to ensure the overall soundness of the loan operations. Credit risk management methods To effectively manage the risk involved in individual loans as well as the credit portfolio as a whole, the Group first acknowledges that every loan entails credit risk, assesses the credit risk posed by each borrower and loan using an internal rating system, and quantifies that risk for control purposes. Credit risk evaluation At SMBC, the Credit & Investment Planning Department manages an internal rating system for each asset control category set according to portfolio characteristics. For example, credits to commercial and industrial (“C&I”) companies, individuals for business purposes (domestic only), sovereigns, public sector entities, and financial institutions are assigned an “obligor grade,” which indicates the borrower’s creditworthiness, and/or “facility grade,” which indicates the collectability of assets taking into account the transaction conditions such as guarantee/collateral, and tenor. The business units determine an obligor grade by first assigning a financial grade using a financial strength grading model and data obtained from the obligor’s financial statements, including net worth and cash flows. The financial grade is then adjusted taking into account the actual state of the obligor’s financial position and qualitative factors to derive the obligor grade. The qualitative factors mainly include the expected future cash flows taking into account factors such as historical loss information, the appropriateness of the borrower’s business plan or operational improvement plan, the status of progress of its plan, and the overall support from financial institutions. In the event that the borrower is domiciled overseas, internal ratings for credit are made after taking into consideration the country rank, which represents an assessment of the credit quality of each country based on its political and economic situation, as well as its current account balance and external debt. Obligor grades and facility grades are reviewed once a year and as otherwise necessary, such as when there are changes in the credit situation. The Group’s subsidiaries carry out credit risk evaluations in line with SMBC. The tables below show the corporate obligor grading system of SMBC. Obligor Grade Definition Borrower Category Domestic (C&I), etc. J1 Very high certainty of debt repayment Normal J2 High certainty of debt repayment J3 Satisfactory certainty of debt repayment J4 Debt repayment is likely but this could change in cases of significant changes in economic trends or business environment depending on the situation J5 No problem with debt repayment over the short term, but not satisfactory over the mid to long term and the situation could change in cases of any changes in economic trends or business environment J6 Currently no problem with debt repayment, but it is highly likely that this could change in cases of significant changes in economic trends or business environment J7 Close monitoring is required due to problems in meeting loan terms and conditions, sluggish/unstable business, or financial problems Borrowers Requiring J7R Obligors with loans that are more than three months past due or with restructured loans within the “Borrowers Requiring Caution” category Substandard J8 Currently not bankrupt, but experiencing business difficulties, making insufficient progress in restructuring, and highly likely to go bankrupt Potentially Bankrupt J9 Though not yet legally or formally bankrupt, has serious business difficulties and rehabilitation is unlikely; thus, effectively bankrupt Virtually Bankrupt J10 Legally or formally bankrupt Bankrupt Borrowers Obligor Grade Definition Borrower Category Overseas (C&I), etc. G1 Very high certainty or high certainty of debt repayment Normal G2 Satisfactory certainty of debt repayment G3 Debt repayment is likely but this could change in cases of significant changes in economic trends or business environment depending on the situation G4 Debt repayment is likely but this could change in cases of significant changes in economic trends or business environment G5 No problem with debt repayment over the short term, but not satisfactory over the mid to long term and the situation could change in cases of any changes in economic trends or business environment G6 Currently no problem with debt repayment, but it is highly likely that this could change in cases of significant changes in economic trends or business environment G7 Close monitoring is required due to problems in meeting loan terms and conditions, sluggish/unstable business, or financial problems Borrowers Requiring G7R Obligors with loans that are more than three months past due or with restructured loans within the “Borrowers Requiring Caution” category Substandard G8 Currently not bankrupt, but experiencing business difficulties, making insufficient progress in restructuring, and highly likely to go bankrupt Potentially Bankrupt G9 Though not yet legally or formally bankrupt, has serious business difficulties and rehabilitation is unlikely; thus, effectively bankrupt Virtually Bankrupt G10 Legally or formally bankrupt Bankrupt Borrowers There are also grading systems for loans to individuals such as housing loans and structured finance including project finance, where the repayment source is limited to the cash flows generated by a particular business or asset. For example, the obligor grade of housing loans is determined taking into account various relevant factors such as proportion of the repayment to revenue, proportion of down payment to the value and past due information. The Credit & Investment Planning Department of SMBC centrally manages the internal rating systems, and designs, operates, supervises and validates the grading models. It validates the grading models (including statistical validation) of main assets following the procedure manual once a year to ensure their effectiveness and suitability. Quantification of credit risk At SMBC, credit risk quantification refers to the process of estimating the degree of credit risk of a portfolio or individual loan taking into account not just the obligor’s probability of default (“PD”), but also the concentration of risk in a specific customer or industry and the loss impact of fluctuations in the value of collateral, such as real estate and securities. Specifically, the PD by grade, loss given default (“LGD”), credit quality correlation among obligors, and other parameter values are estimated using the historical data of obligors and facilities stored in a database to calculate the credit risk. Then, based on these parameters, SMBC runs a simulation of simultaneous default using the Monte Carlo Simulation to calculate SMBC’s maximum loss exposure to the estimated amount of the maximum losses that may be incurred. Based on these quantitative results, SMBC allocates risk capital. Risk quantification is also executed for purposes such as to determine the portfolio’s risk concentration or to simulate economic movements (stress tests), and the results are used for making optimal decisions across the whole range of business operations, including formulating business plans and providing a standard against which individual credit applications are assessed. Credit assessment At SMBC, the credit assessment of corporate loans involves a variety of financial analyses, including cash flows, to predict an enterprise’s capability of loan repayment and its growth prospects. These quantitative measures, when combined with qualitative analyses of industrial trends, the enterprise’s research and development capabilities, the competitiveness of its products or services, and its management caliber, result in a comprehensive credit assessment. The loan application is analyzed in terms of the intended utilization of the funds and the repayment schedule. In the assessment of housing loans for individuals, SMBC employs a credit assessment model based on credit data amassed and analyzed by SMBC over many years, taking into account various relevant factors including proportion of the repayment to revenue, proportion of down payment to the value and past due information. Credit monitoring At SMBC, in addition to analyzing loans at the application stage, the Credit Monitoring System is utilized to reassess obligor grades, and review credit policies for each obligor so that problems can be detected at an early stage, and quick and effective action can be taken. The system includes annual monitoring that is carried out each time the financial results of the obligor enterprise are obtained, as well as ad-hoc Credit portfolio management Risk-taking within the scope of capital To keep the credit risk exposure to a permissible level relative to capital, the Corporate Risk Management Department of the Group sets a credit risk capital limit for internal control purposes. Under this limit, sub-limits Controlling concentration risk As the Group’s equity capital may be materially impaired in the event that the credit concentration risk becomes apparent, the Credit & Investment Planning Department of the Group therefore takes measures to manage concentration risks, such as introducing large exposure limits and conducting intensive loan reviews for obligors with large exposures, with an increased focus on industrial sectors with an excessive concentration of credit risk. Further, to manage country risk, SMBC’s Planning Department of the Global Banking Unit has credit limit guidelines based on each country’s creditworthiness. Toward active portfolio management SMBC’s Credit Portfolio Management Department makes use of credit derivatives, loan asset sales, and other instruments to proactively and flexibly manage its portfolio to stabilize credit risk. Maximum exposure to credit risk before collateral held or other credit enhancements The following table shows the maximum exposure to credit risk before taking into account any collateral held or other credit enhancements at March 31, 2022 and 2021. At March 31, 2022 2021 (In millions) Credit risk exposures relating to assets on the consolidated statements of financial position: Deposits with banks ¥ 74,780,886 ¥ 72,311,473 Call loans and bills bought 1,965,135 2,553,468 Reverse repurchase agreements and cash collateral on securities borrowed 11,303,930 11,738,072 Trading assets 3,489,258 2,732,480 Derivative financial instruments 6,443,748 5,521,617 Financial assets at fair value through profit or loss 1,657,206 1,667,164 Investment securities: Debt instruments at amortized cost 83,954 72,015 Debt instruments at FVOCI 28,066,966 26,392,635 Loans and advances 104,635,815 97,714,938 Other financial assets 5,309,839 4,250,454 Credit risk exposures relating to off-balance (1) Loan commitments 73,246,384 71,677,806 Financial guarantees and other credit-related contingent liabilities 11,722,240 9,872,696 Total ¥ 322,705,361 ¥ 306,504,818 (1) The off-balance Based on the table above, excluding loan commitments (refer to Note 42 “Contingency and Capital Commitments”), the majority of the total exposure to credit risk is derived from “Loans and advances.” Collateral and other credit enhancements The Group considers the acquisition of collateral and guarantees as a secondary repayment source to further enhance loan recovery and minimize credit risk. Based on the assessment of a borrower’s real financial condition and potential future cash flows, the Group shall analyze the borrower’s repayment ability and require sufficient collateral in the form of an asset or third-party obligation. This serves to mitigate the inherent credit risk in the exposure, by either improving recoveries in the event of a default or transferring the borrower’s obligation to guarantors. Collateral received is mainly segregated into (1) financial collateral such as cash, deposits and securities, (2) real estate collateral such as land and buildings, and (3) guarantees received from sovereigns, municipal corporations, credit guarantee corporations and other public entities, financial institutions, and other companies. The Group’s credit risk management is mainly based on an analysis of the repayment ability from the cash flows of the borrower’s business performance, and the collateral and other credit enhancements are considered as secondary repayment sources in the Group’s business practice. At the time of the primary lending decision, the Group evaluates the collateral on an individual borrower basis to consider its financial effect for mitigating credit risk. The re-evaluation The following table shows the financial effect of collateral and other credit enhancements on impaired loans and advances at March 31, 2022 and 2021. The maximum collateral amounts included in the disclosure are limited to the carrying value of loans and advances where the credit exposure is over-collateralized.

(2) The increase in the balance of the total ECL allowance at March 31, 2021 is primarily due to both an increase in loans and advances to corporate borrowers who were severely affected by the COVID-19 (3) Charge-offs for lifetime ECL credit-impaired are primarily related to those for consumer loans. (4) Others mainly include foreign exchange translations. (5) The increase in the balance of the total ECL allowance at March 31, 2022 was primarily due to an increase in the provision for loan losses related to the Group’s corporate customers adversely affected by the situation in Russia and Ukraine and the downgrades of certain large borrowers, which was partially offset by a decrease in the provision recognized in the previous fiscal year related to the Group’s corporate customers affected by the COVID-19 pandemic, as a result of their recovery in the current fiscal year. For additional information, refer to Note 3 “Critical Accounting Estimates and Judgments.” For the fiscal year ended March 31, 2022, the ECL allowance increased by ¥ million from ¥ million at March 31, 2021 to ¥ million at March 31, 2022. The increase was primarily due to an increase in the provision for loan losses related to the Group’s corporate customers adversely affected by the situation in Russia and Ukraine and the downgrades of certain large borrowers, which was partially offset by a decrease in the provision recognized in the previous fiscal year related to the Group’s corporate customers affected by the COVID-19 pandemic, as a result of their recovery in the current fiscal year. For the fiscal year ended March 31, 2022, the obligor grades of a number of Russian borrowers affected by the situation in Russia and Ukraine were downgraded to the extent that the credit risk on loans and advances to such borrowers was determined to be significantly increased since initial recognition and their allowance for loan losses was measured at an amount equal to the lifetime ECL. In addition, the Group evaluated the forward-looking impact on credit risks and losses based on factors such as the possibility that payment of principal or interest would be delayed or requests for loan restructuring would be made due to the prolonged impact of sanctions targeting Russia imposed by the Japanese government and authorities in several other jurisdictions, and Russia’s measures to defend its economy and mitigate the effect of sanctions. For further information about the Group’s critical accounting estimates, see Note 3 “Critical Accounting Estimates and Judgments.” As for the allowance for 12-month for the fiscal year ended March 31, 2022, due to a release of part of the ECL allowance as a result of the recovery from the COVID-19 pandemic. As for the allowance for lifetime ECL not credit-impaired, it decreased by million for the fiscal year ended March 31, 2022, due to an increase in the ECL allowance as a result of the downgrades of certain large borrowers.

(2) There were no debt instruments at amortized cost or debt instruments at fair value through other comprehensive income subject to lifetime ECL at March 31, 2022 and 2021. Credit risk from derivative financial instruments The Group maintains control limits on derivative positions, by both amount and term. At any one time, the amount subject to credit risk is limited to the fair value of derivative financial instruments that are favorable to the Group (i.e., assets where their fair value is positive). The Group’s credit risk from derivatives is mitigated where possible through netting agreements whereby derivative assets and liabilities with the same counterparty can be offset. Netting agreements, such as the ISDA master agreement, allow the netting of obligations arising under all of the derivative transactions that the agreement covers upon the counterparty’s default, regardless of maturity and currency, resulting in a single net claim against the counterparty. The Group’s credit risk is also mitigated by collateral arrangements through the credit support annex, resulting in collateral delivered or received regularly based on the replacement costs of derivatives. Market Risk and Liquidity Risk Market risk is the possibility that fluctuations in interest rates, foreign exchange rates, stock prices or other market prices will change the market value of financial products, leading to a loss. The purpose of market risk management is to keep the market risk exposure to a permissible level relative to capital. Liquidity risk is defined as the uncertainty around the ability to meet debt obligations without incurring unacceptably large losses. An example of such risk is the possible inability to meet current and future cash flow/ collateral needs, both ex

Structured Entities	49 STRUCTURED ENTITIES A structured entity is an entity that has been designed so that voting or similar rights are not the dominant factor in deciding who controls the entity. It often has some or all of the following features or attributes: • restricted activities; • a narrow and well-defined objective; • insufficient equity to permit the structured entity to finance its activities without subordinated financial support; or • financing in the form of multiple contractually linked instruments to investors that create concentrations of credit or other risks (tranches). During the normal course of business, the Group engages in numerous transactions involving structured entities. These structured entities are primarily used to provide the Group and its clients with efficient access to funds or investment opportunities, mainly through securitizations, investment funds and structured finance. Consolidated Structured Entities Structured entities are consolidated if they are controlled by the Group in accordance with the accounting policy as described in Note 2 “Summary of Significant Accounting Policies.” The consolidated structured entities include asset backed commercial paper (“ABCP”) conduits which purchase financial assets such as trade accounts receivable and lease receivables by issuing commercial paper to third-party investors. The Group has contractual agreements to provide liquidity and credit enhancement facilities which can be utilized by those structured entities upon their request. At March 31, 2022 and 2021, the consolidated ABCP conduits had total assets of ¥806,524 million and ¥786,433 million, respectively. The total notional amounts of the liquidity and credit enhancement facilities provided by the Group to the consolidated ABCP conduits at March 31, 2022 and 2021 were ¥1,364,128 million and ¥1,226,930 million, respectively, all were undrawn .

The goodwill was attributable to the profitability of the acquired business and the synergies expected to arise after the acquisition. None of the goodwill recognized is expected to be deductible for income tax purposes. The revenue and profit or loss since the acquisition date to March 31, 2022 and pro forma financial information relating to Fullerton India are immaterial to the consolidated financial statements. The owner of non-controlling Cash consideration paid and cash acquired by obtaining control of the subsidiaries The total amount of cash consideration paid and cash acquired by obtaining control of subsidiaries during the fiscal year ended March 31, 2022 were as follows: For the fiscal year ended (In millions) Cash consideration paid ¥ (230,315 ) Cash and cash equivalents transferred as a result of the acquisitions 14,621 Cash consideration paid, net of cash and cash equivalents acquired by obtaining control of the subsidiaries ¥ (215,694 ) The amounts of assets and liabilities other than cash or cash equivalents in these subsidiaries were ¥387,899 million and ¥334,272 million, respectively. Fiscal Year Ended March 31, 2021 There were no material acquisitions that were accounted for as business combinations during the fiscal year ended March 31, 2021. Fiscal Year Ended March 31, 2020 Daiwa SB Investments Ltd. (currently merged into Sumitomo Mitsui DS Asset Management Company, Limited) On April 1, 2019, Sumitomo Mitsui Asset Management Company, Limited (“SMAM”), the Group’s subsidiary, merged with Daiwa SB Investments Ltd. (“DSBI”), previously the Group’s associate, to form Sumitomo Mitsui DS Asset Management Company, Limited (“SMDAM”). The Group’s equity interest in SMDAM resulting from the merger is 50.12%, and as such, SMDAM is the Group’s subsidiary. This merger was made for the purpose of establishing an asset management company that combines the strengths and expertise of SMAM and DSBI, and offers high quality investment management performance and services in order to properly address client needs. The fair values of assets and liabilities of DSBI at the date of acquisition and the consideration paid were as follows: At April 1, 2019 (In millions) Assets: (1) Cash and deposits with banks ¥ 22,798 Intangible assets 20,078 Trading assets 14,019 All other assets 8,284 Total assets ¥ 65,179 Liabilities ¥ 18,038 Net assets ¥ 47,141 Non-controlling (23,093 ) Net assets acquired 24,048 Goodwill 17,022 Consideration ¥ 41,070 Consideration: Fair value of total consideration transferred ¥ 959 Fair value of the equity interest in DSBI held before the acquisition 40,111 Total ¥ 41,070 Acquisition related costs recognized as an expense in “General and administrative expenses” in the consolidated income statement ¥ 9 (1) The fair value of DSBI’s assets at the date of acquisition included the outstanding balance arising from the transactions made between the Group and DSBI, which included deposits with the Group amounting to ¥21 billion.

The Group’s interest in SMAM decreased from 51.19% to 50.12% and its interest in DSBI increased from 48.96% to 50.12% substantially as a result of a stock issuance from SMDAM to the shareholders of DSBI at the date of the business combination. The goodwill was attributable to the profitability of the acquired business and the synergies expected to arise after the acquisition. None of the goodwill recognized is expected to be deductible for income tax purposes. The Group recognized a profit of ¥21,998 million on this step acquisition, which was included in “Other income” in the consolidated income statements.

Text block [abstract]
Basis of Preparation	Basis of Preparation Compliance with International Financial Reporting Standards The consolidated financial statements of the Group have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). Basis of measurement The consolidated financial statements have been prepared under the historical cost basis except for the following: • trading assets and liabilities are measured at fair value; • derivative financial instruments are measured at fair value; • financial assets and liabilities at fair value through profit or loss are measured at fair value; • investment securities at fair value through other comprehensive income are measured at fair value; and • liabilities and the assets recognized in consolidated statements of financial position in respect of defined benefit plans are the present value of the defined benefit obligation less the fair value of plan assets. Functional and presentation currency The consolidated financial statements are presented in Japanese yen, which is also the Company’s functional currency. All financial information presented in Japanese yen has been rounded to the nearest million, except as otherwise indicated. Critical accounting estimates and judgments The preparation of the consolidated financial statements in accordance with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise judgment in the process of applying the accounting policies. Actual results may differ from these estimates. The notes to the consolidated financial statements set out areas involving a higher degree of judgment or complexity, or areas where assumptions are significant to the consolidated financial statements, such as allowance for loan losses (Notes 10, 33), fair value of financial instruments (Note 44), impairment of property, plant and equipment (Note 12), impairment of intangible assets (Note 14), provision for interest repayment (Note 21), retirement benefits (Note 24) and deferred tax assets (Note 23). Refer to Note 3 “Critical Accounting Estimates and Judgments” for further information.
New and Amended Accounting Standards Adopted by the Group	New and Amended Accounting Standards Adopted by the Group During the fiscal year ended March 31, 2022, a number of amendments to standards have become effective; however, they have not resulted in any material changes to the Group’s accounting policies, except as described below. Interest Rate Benchmark Reform—Phase 2 (Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16) In August 2020, the IASB issued “Interest Rate Benchmark Reform—Phase 2: Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16” in response to the reform of interest rate benchmarks such as interbank offered rates (“IBORs”). The amendments supplement the amendments to IFRS 9 “Financial Instruments,” IAS 39 “Financial Instruments: Recognition and Measurement” and IFRS 7 “Financial Instruments: Disclosures” issued in 2019 and focus on the effects on entities’ financial statements when entities replace the previous interest rate benchmark with an alternative interest rate benchmark as a result of the reform. The amendments provide a practical expedient for modifications of financial assets and financial liabilities required as a direct consequence of the reform and made on an economically equivalent basis and a temporary exception to specific hedge accounting requirements, and support entities in providing useful information to users of financial statements. The amendments are effective for annual periods beginning on or after January 1, 2021. On April 1, 2021, the Group adopted the amendments.
Consolidation	Consolidation Subsidiaries Subsidiaries are all entities controlled by the Group. The Group controls an entity when it is exposed, or has rights, to variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. The Group considers all facts and circumstances whether it controls an entity. Where the relevant activities are directed through voting or similar rights, the Group considers that it controls an entity if it has the existing rights that give it the current ability to direct the operating and financing policies of the entity, in general by having a shareholding of more than 50% of the voting rights. The existence and effect of potential voting rights that are deemed to be substantive are taken into account when assessing whether the Group controls another entity. Where the voting rights are not the dominant factor in deciding who controls the entity, the assessment of control is more complex and requires greater use of judgment. The Group assesses whether it controls an entity considering all facts and circumstances, such as the purpose and design of the entity, the relevant activities and how to make decisions about those activities. The Group also determines whether it is acting as an agent or a principal parties and therefore does not control the entity. To make such judgments, the Group considers the overall relationship, especially all of the following factors: the scope of its decision-making authority over the entity, the rights held by other parties, the remuneration to which it is entitled in accordance with the remuneration agreement, and its exposure to variability of returns from other interests that it holds in the entity. The Group reassesses whether it controls an entity if facts and circumstances indicate that there are changes to one or more of the elements of control. Subsidiaries are fully consolidated from the date on which the Group obtains control. They are deconsolidated from the date on which the Group loses control. The acquisition method is used to account for the business combinations including the acquisition of subsidiaries by the Group. The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the acquisition-date fair values of the assets transferred, the liabilities incurred and the equity interests issued. Identifiable assets acquired and liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. The Group’s previously held equity interest in the acquiree is remeasured at fair value at the acquisition date and any gain or loss is recognized in profit or loss. For each business combination, the Group measures any non-controlling non-controlling non-controlling non-controlling Inter-company transactions, balances and unrealized gains on transactions between the Group companies are eliminated on consolidation. Unrealized losses are also eliminated unless the transaction provides evidence of impairment of the asset transferred. The accounting policies of subsidiaries have been adjusted where necessary to ensure consistency with the accounting policies adopted by the Group. Non-controlling Changes in the Group’s ownership interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions. Interests in the equity of subsidiaries not attributable to the Group are reported in the consolidated statements of financial position as a separate component of equity as non-controlling non-controlling Associates and joint ventures An associate is an entity over which the Group has significant influence, but does not control the financial and operating policy decisions of the entity. Significant influence is generally presumed to exist when the Group holds 20% or more, but less than 50%, of the voting rights. Entities that are jointly controlled by more than one party, including the Group, may be determined to be a joint venture. The Group accounts for investments in associates and joint ventures using the equity method from the date on which they become associates or joint ventures. The Group discontinues the use of the equity method from the date on which the Group ceases to have significant influence or joint control over the investees. Under the equity method, the Group’s investments in associates and joint ventures are initially recognized at cost. The carrying amount of the investments are subsequently increased or decreased to recognize the Group’s share of the post-acquisition profit or loss of the associate or joint venture and other movements included directly in the equity of the associate or joint venture. The Group’s share of the results of associates and joint ventures is based on the financial statements of its associates and joint ventures, adjusted to conform with the accounting policies of the Group. Profits on transactions between the Group and its associates and joint ventures are eliminated to the extent of the Group’s interest in the associates or joint ventures. Losses are also eliminated to the extent of the Group’s interest in the associates or joint ventures unless the transaction provides evidence of impairment in the asset transferred. The carrying amounts of the investments in associates and joint ventures include goodwill (net of any accumulated impairment loss) arising on the acquisition of the interests in the entities. Because goodwill arising on the acquisition of the interest in an associate or joint venture is not separately recognized, it is not tested for impairment separately. Instead, the entire carrying amount of the investment in an associate or joint venture is tested for impairment as a single asset by comparing its recoverable amount, which is the higher of value in use and fair value less costs to sell, with its carrying amount, whenever there is any objective evidence that the investment is impaired. An impairment loss recognized in prior periods for the investment is reversed only if there has been a change in the estimates used to determine the recoverable amount of the investment since the last impairment loss was recognized. If this is the case, the carrying amount of the investment is increased to its recoverable amount. That increase is a reversal of an impairment loss. When the Group’s share of losses in an associate or joint venture exceeds the Group’s carrying amount of the investment, the Group does not recognize further losses, unless it has a binding obligation or has made payments on behalf of the entity.
Segment Reporting	Segment Reporting The Group determines its operating segments based on the management approach, which requires operating segments to be identified on the basis of internal reports about components of the entity that are regularly reviewed by management, in order to allocate resources to a segment and to assess its performance.
Foreign Currency Translation	Foreign Currency Translation Items included in the financial statements of each of the Group companies are measured using the currency of the primary economic environment in which the company operates (“the functional currency”). The consolidated financial statements are presented in Japanese yen, which is also the Company’s functional currency. Transactions and balances Foreign currency transactions that are denominated or settled in a foreign currency are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Monetary items denominated in foreign currencies are translated using the exchange rate at the end of the reporting period. Foreign exchange gains and losses resulting from the retranslation and settlement of monetary items are recognized in the consolidated income statements. Non-monetary Non-monetary functional Foreign operations The assets and liabilities of foreign operations are translated into the presentation currency of the Group using the exchange rate at the end of the reporting period, and their income statements are translated using the exchange rates at the dates of the transactions or average exchange rates where these approximate to actual rates. The exchange differences arising on the translation of a foreign operation are included in other comprehensive income within equity and subsequently included in profit or loss on the disposal or partial disposal of the operation.
Financial Assets	Financial Assets Regular way purchases and sales of financial assets are recognized and derecognized on the trade date—the date on which the Group commits to purchase or sell the assets. Financial assets are derecognized when the contractual rights to receive cash flows from the financial assets have expired or where the Group has transferred substantially all the risks and rewards of ownership of the financial assets at a consolidated level. The Group consolidates all subsidiaries in accordance with IFRS 10 “Consolidated Financial Statements” before determining derecognition of financial assets. IFRS 9 requires all financial assets, including entire hybrid instruments, to be classified into three measurement categories, namely, amortized cost, fair value through other comprehensive income (“FVOCI”) and fair value through profit or loss (“FVPL”), based on the business model within which they are held and their contractual cash flow characteristics. The Group has assessed the business models based on facts and circumstances at a portfolio level. Factors that are considered in determining the business model include policies and objectives for the relevant portfolio, how the performance and risks of the portfolio are managed, evaluated and reported to management, and the level of sales activity. The Group has assessed the contractual cash flow characteristics of financial assets with reference to whether the contractual cash flows are solely payments of principal and interest (“SPPI”). Principal is defined as the fair value of the financial asset at initial recognition but it may change over the life of the financial asset as amounts are repaid. Interest is defined as consideration for the time value of money and the credit risk associated with the principal amount outstanding during a particular period of time. It can also include consideration for other basic lending risks such as liquidity risk and costs such as administrative costs associated with holding the financial asset for a particular period of time, as well as a profit margin. In assessing whether the contractual cash flows meet the conditions for SPPI, the Group considers the contractual terms of the financial asset. This includes assessing whether the financial asset contains a contractual term that could change the contractual cash flows so that it would not meet the conditions for SPPI, including leverage features, contingent events that would change the amount or timing of cash flows, contractual terms that limit the Group’s claim to cash flows from specified assets, and features that modify consideration of the time value of money. Financial assets measured at amortized cost Financial assets are measured at amortized cost if they are held within a business model whose objective is to hold the assets in order to collect contractual cash flows, and their contractual cash flows are SPPI. These financial assets are mainly included in “Loans and advances” and also in “Investment securities” in the consolidated statements of financial position. They are initially recognized at fair value plus transaction costs that are directly attributable to the acquisition of the financial assets, and are subsequently measured at amortized cost using the effective interest method. Interest income on these financial assets using the effective interest method is recognized Financial assets measured at fair value through other comprehensive income Financial assets are measured at FVOCI if they are held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets, and their contractual cash flows are SPPI. Financial assets measured at FVOCI are included in “Investment securities” in the consolidated statements of financial position. They are initially recognized at fair value plus transaction costs that are directly attributable to the acquisition of the financial assets, and are subsequently measured at fair value. Gains and losses arising from changes in the fair value of these financial assets are recognized in other comprehensive income, until they are derecognized. At the time of derecognition, the cumulative gains or losses previously recognized in other comprehensive income are reclassified to profit or loss and are recognized in “Net investment income” in the consolidated income statements. Interest income calculated using the effective interest method, foreign currency gains and losses, and impairment gains and losses are recognized in “Net interest income,” “Net trading income” and “Impairment charges on financial assets” in the consolidated income statements, respectively. In addition, the Group makes an irrevocable election at initial recognition, for particular non-trading Financial assets measured at fair value through profit or loss Any financial assets that do not meet the criteria of amortized cost or FVOCI are classified as FVPL, unless the Group makes an irrevocable election for non-trading Financial assets are classified as held for trading and are included in “Trading assets” in the consolidated statements of financial position, if they are acquired principally for the purpose of selling in the near term or if they are part of a portfolio of identified financial instruments that are managed together and for which there is evidence of a recent actual pattern of short-term profit-taking. Derivatives which are not designated as hedging instruments are classified as held for trading, and all derivatives are included in “Derivative financial instruments” in the consolidated statements of financial position. All derivatives are carried as assets when the fair value is positive and as liabilities when the fair value is negative. Financial assets mandatorily measured at FVPL, other than those held for trading and derivatives, are included in “Financial assets at fair value through profit or loss” in the consolidated statements of financial position. The financial assets mentioned above are initially recognized at fair value with transaction costs being recognized in profit or loss, and are subsequently measured at fair value. Gains and losses arising from changes in the fair values of trading assets and derivatives held for trading, and interest and dividend income on trading assets are included in “Net trading income” in the consolidated income statements. Gains or losses arising from financial assets mandatorily measured at FVPL are included in “Net income (loss) from financial assets and liabilities at fair value through profit or loss” in the consolidated income statements. Additionally, financial assets measured at amortized cost or FVOCI can be designated at initial recognition to be measured at FVPL in order to eliminate or significantly reduce a measurement or recognition inconsistency. The Group does not make this designation.
Financial Liabilities	Financial Liabilities Financial liabilities measured at amortized cost Financial liabilities, except for financial liabilities measured at FVPL Financial liabilities measured at fair value through profit or loss Financial liabilities measured at FVPL consist of financial liabilities held for trading, derivatives whose fair values are negative and financial liabilities designated at FVPL. Financial liabilities are classified as held for trading if they are incurred principally for the purpose of repurchasing in the near term or if they are part of a portfolio of identified financial instruments that are managed together and for which there is evidence of a recent actual pattern of short-term profit-taking. Financial liabilities held for trading are included in “Trading liabilities” in the consolidated statements of financial position. Trading liabilities are initially recognized at fair value with transaction costs being recognized in profit or loss, and are subsequently measured at fair value. Gains and losses arising from changes in the fair values of trading liabilities and interest expense on trading liabilities are included in “Net trading income” in the consolidated income statements. For derivatives other than the component of hybrid instrument, refer to “Financial assets measured at fair value through profit or loss.” The derivative component of a hybrid instrument containing both a derivative and non-derivative The Group applies a fair value option to certain financial liabilities which were issued by the Group’s securities subsidiary. As part of risk management, the Group enters into derivative transactions to offset the profit or loss of financial liabilities containing embedded derivatives, designated at FVPL under the fair value option. The Group can make an irrevocable election for each individual financial liability at initial recognition to designate it as measured at FVPL, if it meets one of the following criteria: • The designation eliminates or significantly reduces a measurement or recognition inconsistency (referred to as “an accounting mismatch”) that would otherwise arise from measuring assets or liabilities or recognizing the gains and losses on them on different bases; • A group of financial liabilities or financial assets and financial liabilities is managed, and its performance is evaluated on a fair value basis, in accordance with a documented risk management or investment strategy, and information about the group is provided internally on that basis to the board of directors; or • The financial liability contains one or more embedded derivatives which significantly modify the cash flows and it is not clear with no analysis that separation is prohibited. The financial liabilities designated at FVPL are presented as “Financial liabilities designated at fair value through profit or loss” in the consolidated statements of financial position. Those liabilities are initially recognized at fair value with transaction costs being recognized in profit or loss, and are subsequently measured at fair value. The amount of changes in their fair values that is attributable to changes in own credit risk of the liabilities is recognized in other comprehensive income and subsequently not transferred to profit or loss. The amount of changes in their fair values except for the effects of changes in their own credit risk, gains or losses on derecognition and interest expense are included in “Net income (loss) from financial assets and liabilities at fair value through profit or loss” in the consolidated income statements. Financial liabilities are derecognized when they have been redeemed or otherwise extinguished.
Hedge Accounting	Hedge Accounting The Group applies fair value hedge accounting and hedge accounting of net investments in foreign operations, in order to reflect the effect of risk management activities on its consolidated financial statements. Fair value hedges The Group applies fair value hedge accounting in order to reflect in its consolidated financial statements the effect of risk management activities to mitigate the risk of changes in the fair value of certain fixed rate financial assets and liabilities. The Group designates certain interest rate derivatives as hedging instruments. Changes in fair values of hedging instruments are recognized in the consolidated income statements, together with changes in fair value of the hedged item attributable to the hedged risk. The hedging gain or loss on the hedged item held at amortized cost adjusts the carrying amount of the hedged item, and is recognized in “Net trading income” in the consolidated income statements. If the hedged item is a financial asset measured at FVOCI, the hedging gain or loss on the hedged item is recognized in “Net trading income” in the consolidated income statements. If the hedge no longer meets the criteria for hedge accounting for reasons other than the derecognition of the hedged item, the adjustment to the hedged item for which the effective interest method is used, is amortized to profit or loss over the period to maturity of the hedged item. When the hedged item is derecognized, the adjustment is recognized immediately in the consolidated income statements. The Group also applies fair value hedge accounting in order to reflect in its consolidated financial statements the effect of risk management activities to mitigate the risk of changes in fair values of certain equity instruments elected to be measured at FVOCI. The Group designates equity derivatives as hedging instruments. Both the effective portion and ineffective portion of changes in the fair value of the hedging instruments are recognized in other comprehensive income, and amounts presented in other comprehensive income are not subsequently transferred to profit or loss. Hedges of net investments in foreign operations The Group applies hedge accounting of net investments in foreign operations in order to reflect in its consolidated financial statements the effect of risk management activities to mitigate the foreign currency risk of exchange differences arising from the translation of net investments in foreign operations. The Group designates currency derivatives and foreign currency denominated financial liabilities as hedging instruments. The effective portion of the gain or loss on the hedging instruments is recognized in other comprehensive income, whereas the ineffective portion of the gain or loss on the hedging instruments is recognized in “Net trading income” in the consolidated income statements. The cumulative gain or loss recognized in other comprehensive income is reclassified to profit or loss on the disposal or partial disposal of foreign operations. For further information about hedge accounting, see Note 7 “Derivative Financial Instruments and Hedge Accounting—Hedge accounting.” Interest Rate Benchmark Reform The Group applies “Interest Rate Benchmark Reform, Amendments to IFRS 9, IAS 39 and IFRS 7.” The amendments provide reliefs from applying specific hedge accounting requirements to hedging relationships directly affected by the interest rate benchmark reform only if the reform gives rise to uncertainties. The reliefs aim to ensure that the interest rate benchmark reform does not result in the discontinuance of hedge accounting. In accordance with the transition provisions, the amendments have been adopted retrospectively to hedging relationships that existed at the beginning of the reporting period or were designated thereafter. The reliefs adopted by the Group are described below. • Prospective assessments The Group has assumed that the interest rate benchmarks on which the hedged risk or the cash flows of the hedging instrument is based are not altered as a result of the interest rate benchmark reform in assessing whether there is an economic relationship between the hedged item and the hedging instrument. • Hedge of a non-contractually The Group has assessed whether a non-contractually
Offsetting Financial Instruments	Offsetting Financial Instruments Financial assets and liabilities are offset and the net amount is reported in the consolidated statements of financial position, only if the Group currently has a legally enforceable right to set off the recognized amounts and intends to settle on a net basis or to realize the asset and settle the liability simultaneously. In all other situations, they are presented on a gross basis.
Fair Value Measurement	Fair Value Measurement Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining the fair value, the Group gives the highest priority to a quoted price in an active market for identical assets or liabilities. A market is regarded as active if transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis. If there is no active market for the asset or liability, the Group uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure the fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. In cases where the Group manages a group of financial assets and financial liabilities on the basis of its net credit risk exposure, the fair value of the group of financial assets and financial liabilities is measured on the basis of the price that would be received to sell a net long position (i.e., an asset) or paid to transfer a net short position (i.e., a liability) for the credit risk exposure provided that certain criteria set forth in IFRS 13 “Fair Value Measurement” are met. Details of fair value measurement are described in Note 44 “Fair Value of Financial Assets and Liabilities.”
Recognition of Deferred Day One Profit and Loss	Recognition of Deferred Day One Profit and Loss The best evidence of the fair value of a financial instrument at initial recognition is normally the transaction price (i.e., the fair value of the consideration given or received). However, if the fair value at initial recognition is not evidenced by a quoted price in an active market for an identical asset or liability nor based on a valuation technique that uses only data from observable markets, the difference between the fair value at initial recognition and the transaction price, commonly referred to as “day one profit and loss,” is not recognized as a gain or loss but is adjusted to be deferred. The Group has certain financial instruments, such as derivatives, hybrid financial instruments and certain loans and advances classified as FVPL where fair value is determined using valuation techniques for which not all inputs are observable in a market. Such a financial instrument is initially recognized at the transaction price which may be different from the fair value, and the day one profit and loss is not recognized as a gain or loss. The timing of recognition of the deferred day one profit and loss is determined on an instrument by instrument basis. It is either amortized over the life of the transaction, deferred until fair value of the instrument can be determined using data from observable markets, or realized due to redemption or sales of the instrument .
Repurchase and Reverse Repurchase Agreements, and Securities Borrowing and Lending Agreements	Repurchase and Reverse Repurchase Agreements, and Securities Borrowing and Lending Agreements In the ordinary course of business, the Group lends or sells securities under agreements to repurchase them at a predetermined price on a future date (“repos”). Since substantially all the risks and rewards of ownership are retained by the Group, the securities remain on the consolidated statements of financial position and a liability is recorded in respect of the consideration received. On the other hand, the Group borrows or purchases securities under agreements to resell them at a predetermined price on a future date (“reverse repos”). Since the Group does not retain the risks and rewards of ownership of the financial assets, these transactions are treated as collateralized loans and the securities are not included in the consolidated statements of financial position. The Group measures repos and reverse repos at amortized cost. The difference between the sale and purchase price is accrued over the life of the transactions. Securities lent to counterparties remain on the consolidated statements of financial position. Securities borrowed are not recognized in the consolidated statements of financial position, unless these are sold to third parties, at which point the obligation to repurchase the securities is measured at fair value and included in “Trading liabilities” in the consolidated statements of financial position and any subsequent gain or loss is included in “Net trading income” in the consolidated income statements. For the fiscal years ended March 31, 2022 and 2021, there were no transactions pursuant to repurchase agreements, securities lending transactions or other transactions involving the transfer of financial assets with an obligation to repurchase such transferred assets that were treated as sales and hence derecognized for accounting purposes.
Impairment of Financial Assets	Impairment of Financial Assets The expected credit losses (“ECL”) model is used for the recognition of impairment loss under IFRS 9. The ECL model applies to financial assets measured at amortized cost, and debt instruments at FVOCI, lease receivables, certain loan commitments and financial guarantee contracts. Under the ECL model, an entity is required to account for expected credit losses from initial recognition of financial instruments and to recognize full lifetime expected losses on a timely basis. Determining significant increase in credit risk At each reporting date, credit risk on a financial asset is assessed and a loss allowance is measured at an amount equal to the ECL resulting from default events that are possible within the next 12 months, if the credit risk has not increased significantly since initial recognition (“Stage 1”). A loss allowance is measured at an amount equal to the ECL resulting from all possible default events over the expected life of the financial assets which are assessed to have experienced a significant increase in credit risk since initial recognition (“Stage 2”) or the credit-impaired financial assets (“Stage 3”). The expected life of a financial asset is the maximum contractual period over which it is exposed to credit risk. However, for certain revolving facilities including both a loan and an undrawn component, such as retail overdrafts and credit card facilities, the contractual ability to demand repayment and cancel the undrawn commitment does not limit the exposure to credit losses to the contractual notice period. The expected life of these revolving facilities is derived from the behavioral life calculated based on historical Assessments on significant increases in credit risk are performed on an individual financial asset basis. The Group performs ECL recognition and measurement on a collective basis or an individual basis using reasonable and supportable information that is available without undue cost or effort, such as asset type, credit risk ratings, collateral collectability, past-due The Group determines whether there has been a significant increase in credit risk by comparing the risk of a default occurring on a financial instrument at the reporting date with that at the date of initial recognition, based on quantitative and qualitative assessments. As for the quantitative assessment, the Group measures increase of probability of default (“PD”) since initial recognition. If an obligor gets downgraded to a certain degree which reflects an increase of PD exceeding the threshold defined, a significant increase in credit risk is recognized. For example, origination obligor grade getting down by one to four grades is taken as a significant increase in credit risk where PD has increased since initial recognition. Numbers of obligor grade deterioration taken to identify significant increase in credit risk depend on credit quality at origination. The origination obligor grade with lower credit rating takes less downgrades to identify significant increase in credit risk than those with higher credit rating, due to the difference in increase of PD. Refer to Note 46 “Financial Risk Management” for information on obligor grading system of SMBC. As for the qualitative assessment, the Group evaluates credit risk characteristics of financial assets in accordance with the Group’s credit risk management practices. For example, certain financial assets that meet high credit risk criteria are transferred to Stage 2 from Stage 1. Moreover, financial assets whose principal and/or interest payments are more than 30 days past due are transferred to Stage 2. If there is no longer any observation of a significant increase in credit risk, the financial instrument will be transferred to Stage 1. Determining credit-impaired financial assets A financial asset is credit-impaired and classified to Stage 3 when one or more events that have a detrimental impact on the estimated future cash flows of that financial asset have occurred. The criteria that the Group uses to determine that a financial asset is credit-impaired include: • significant financial difficulty of an issuer or a borrower; • a default or delinquency as more than 90 days past due in interest or principal payments; • restructuring of a financial asset by the Group due to the borrower’s financial difficulties; • indications that a borrower or issuer will enter bankruptcy; and • the disappearance of an active market for that financial asset because of the borrower’s financial difficulties. If a financial asset is no longer credit-impaired, it will be transferred to Stage 2 or Stage 1. The definition of default used for ECL recognition and measurement is consistent with that used for the Group’s internal credit risk management purposes. The Group manages credit risk with an internal credit rating system, which is consisted of the borrower categories to substandard borrowers, potentially bankrupt borrowers, virtually bankrupt borrowers, and bankrupt borrowers defined as default for ECL application (see Note 46 “Financial Risk Management”). Purchased or originated credit-impaired financial assets (“POCI”) are financial assets considered credit-impaired at the time of initial recognition. They are measured at fair value on initial recognition and therefore no credit loss allowance is initially recognized. Subsequently, lifetime expected credit losses for POCI are measured as the difference between the financial asset’s amortized cost and the present value of future cash flows discounted at the financial asset’s credit-adjusted effective interest rate changes Measurement of Expected Credit Losses The Group measures ECL of a financial asset in a way that reflects an unbiased and probability-weighted amount, the time value of money, and reasonable and supportable information that is available at the reporting date about past events, current conditions and forecasts of future economic conditions. The ECL models have been built by leveraging the PD, loss given default (“LGD”) and exposure at default (“EAD”) used in the Basel III regulatory framework, for instance by adjusting certain conservative factors in those PDs and LGDs. For financial assets at Stage 1 and Stage 2, the Group uses the 12-month 12-month The DCF method is used to measure the ECL, which is the difference between the financial asset’s carrying amount and the present value of estimated future cash flows discounted at the financial asset’s original effective interest rate. If financial assets have a variable interest rate, the discount rate for measuring any impairment loss is the effective interest rate determined under the contract, for the current period. The estimated future cash flows are individually calculated taking into account factors including historical loss information, the appropriateness of the borrower’s business plan or operational improvement plan, the status of progress of its plan, the overall support from financial institutions, and the realizable value of any collateral held. Cash flows are probability-weighted by reference to different scenarios. The Group incorporates forward-looking information into the ECL measurement by obligor grading, macroeconomic factors and additional ECL adjustments as appropriate. Obligor-specific forward-looking information is reflected in the obligor grade as a qualitative assessment. Refer to Note 46 “Financial Risk Management” for information on obligor grading system of SMBC. To incorporate forward-looking information into the ECL models, the Group introduces an approach based on multiple scenarios. In this approach, three scenarios (base, upside and downside scenarios) are modelled to ensure an unbiased ECL calculation. Information considered in the development of the base scenario is aligned with information used for strategic planning, budgeting and risk management of the Group, and includes not only internal information but external information including economic data and forecasts publicly provided by Japanese governmental bodies, research institutes of the private-sector and international organizations conducting economic analysis and projections. The downside scenario is the adverse scenario and based on the stressed business environments such as serious economic recession and financial market disruption. Both the downside scenario and the upside scenario, which is the favorable scenario, are developed based on the premises of the base scenario and the past macroeconomic experiences. The Group has lower weights for the downside scenario and the upside scenario compared with the base scenario. Furthermore, additional ECL adjustments are applied in cases where known or expected risk factors or information have not been specifically considered in the ECL model and thus the ECL does not fully reflect current circumstances, events or conditions at relevant portfolio level. The Group has identified the key macroeconomic drivers impacting the credit ECLs are recognized through loss allowance accounts. Changes in the carrying amount of the loss allowance accounts are recognized as an impairment gain or loss and included in “Impairment charges on financial assets” in the consolidated income statements. If a financial asset is determined to be uncollectible, it is written off against the related allowance for loan impairment. Uncollectible financial assets are normally written off when there is no reasonable expectation of further recovery after any collateral is foreclosed and the amount of the loss has been determined. Those assets primarily include loans to borrowers that have been legally or formally declared bankrupt and borrowers that may not have been legally or formally declared bankrupt but are essentially bankrupt. If contractual terms of a loan have been modified, it is required to recalculate the gross carrying amount of that loan and recognize a modification gain or loss in profit or loss. Moreover, it is required to assess whether there has been a significant increase since initial recognition and the Group conducts analysis to monitor the change in credit risk subsequent to modification. However, if the new contractual terms are considered substantially different from the existing contractual terms, a new loan will be recognized at fair value and the existing loan will be derecognized.
Property, Plant and Equipment	Property, Plant and Equipment All property, plant and equipment are stated at cost less accumulated depreciation and accumulated impairment losses, if any. Additions and subsequent expenditures are capitalized only to the extent that they enhance the future economic benefits expected to be derived from the assets. Repairs and maintenance costs are expensed as incurred. Land is not depreciated. Depreciation of other assets is calculated using the straight-line method to allocate their cost to their residual values over their estimated useful lives, as follows: • Buildings: 7–50 years; • Right of use assets: the shorter of the lease term and the estimated useful life, which is generally 1–20 years; and • Assets for rent and others: 2–40 years. The residual values and useful lives are reviewed and adjusted, if appropriate, at the end of each reporting period. Gains and losses on disposal are determined by comparing the proceeds with the carrying amount. These are included in “Other income” and “Other expenses” in the consolidated income statements.
Intangible Assets	Intangible Assets Goodwill Goodwill represents the excess of the aggregate non-controlling Software Purchased software is carried at cost less accumulated amortization and accumulated impairment losses, if any. Expenditure on internally generated software is recognized as an asset if the Group can demonstrate its intention and ability to complete the development and use the software in a manner that will generate future economic benefits and it can reliably measure the costs to complete the development. Internally generated software is carried at capitalized cost less accumulated amortization and accumulated impairment losses, if any. Costs associated with maintaining software are expensed as incurred. Software is amortized using the straight-line method over the estimated useful life, which is generally 5 to 10 years. Contractual customer relationships and trademarks Contractual customer relationships and trademarks acquired in a business combination are recognized at fair value at the acquisition date. Contractual customer relationships and trademarks are carried at cost less accumulated amortization or impairment losses, if any. Contractual customer relationships and trademarks are amortized using the straight-line method over their estimated useful lives, which are generally 5 to 20 years. Other intangible assets Other intangible assets primarily consist of leasehold rights. They are recognized only when the Group legally obtains the rights and can reliably measure the fair value. Leasehold rights have an indefinite useful life and they are not amortized but are tested for impairment annually.
Impairment of Non-Financial Assets	Impairment of Non-Financial Non-financial For the purposes of conducting impairment reviews, assets are grouped into cash-generating units to which the assets belong. Non-financial
Assets Held for Sale	Assets Held for Sale Non-current
Leases	Leases The Group assesses whether the contract is, or contains, a lease at the inception of a contract. A lease is a contract that conveys the right to control the use of an identified asset for a period of time in exchange for consideration As lessee At the commencement date, the Group recognizes a lease liability and measures it at the present value of the lease payments that are not paid at that date. The lease payments are discounted using the interest rate implicit in the lease, or the Group’s incremental borrowing rate if the interest rate implicit in the lease cannot be readily determined. After the commencement date, the Group measures the lease liability by increasing the carrying amount to reflect interest on the lease liability and reducing the carrying amount to reflect the lease payments made. The lease liabilities are included in “Borrowings” in the consolidated statements of financial position. The Group also recognizes a right of use asset and measures it at cost at the commencement date. The cost of the right of use asset comprises the amount of the initial measurement of the lease liability, any lease payments made at or before the commencement date, less any lease incentives received and any initial direct costs incurred. After the commencement date, the Group measures the right of use asset applying a cost model. The right of use asset is depreciated from the commencement date to the earlier of the end of the useful life of the right of use asset or the end of the lease term. The lease term is determined as the non-cancellable As lessor A lease is classified as a finance lease if it transfers substantially all the risks and rewards incidental to ownership of an underlying asset. A lease is classified as an operating lease if it does not transfer substantially all the risks and rewards incidental to ownership of an underlying asset. When the Group acted as a lessor in an operating lease, the underlying assets were included in “Property, plant and equipment” in the consolidated statements of financial position and were depreciated over their expected useful lives on a basis consistent with similar assets in property, plant and equipment. Lease payment from operating leases as income was recognized on a straight-line basis over the lease term and included in “Other income” in the consolidated income statements. Initial direct costs incurred in obtaining an operating lease were added to the carrying amount of the underlying assets and recognized as an expense on a straight-line basis over the lease term. When the Group was a lessor in a finance lease, the lease receivables were recognized at an amount equal to the net investment in the lease and included in “Loans and advances” in the consolidated statements of financial position. Finance income was recognized over the lease term based on a pattern reflecting a constant periodic rate of return on the net investment in the finance lease and included in “Interest income” in the consolidated income statements. Sale and leaseback A sale and leaseback qualifies as a sale if the buyer-lessor obtains control of the underlying amount of the asset that relates to the right of use retained. The seller-lessee recognizes only the amount of any gain or loss that relates to the rights transferred to the buyer-lessor. If the fair value of the consideration for the sale of an asset does not equal the fair value of the asset or if the lease payments are not at market rates, the difference is accounted for as either a prepayment of lease payments (if the purchase price is below market terms) or an additional financing (if the purchase price is above market terms) to measure the sale proceeds at fair value.
Cash and Cash Equivalents	Cash and Cash Equivalents For the purposes of the consolidated statements of cash flows, cash and cash equivalents include cash on hand, demand deposits, and other short-term highly liquid financial assets with original maturities of three months or less, which are subject to insignificant risk of changes in their fair value.
Provisions	Provisions A provision is recognized if, as a result of a past event, the Group has a present legal or constructive obligation that can be estimated reliably and it is probable that an outflow of economic benefits will be required to settle the obligation. Provisions are determined by discounting the expected future cash flows at a pre-tax
Financial Guarantee Contracts	Financial Guarantee Contracts Financial guarantee contracts are contracts that require the issuer to make specified payments to reimburse the holder for a loss it incurs when a specified debtor fails to make payments due in accordance with the original or modified terms of a debt instrument. Such financial guarantees are given to banks, financial institutions and other bodies on behalf of customers to secure loans, overdrafts and other banking facilities. Financial guarantees are initially recognized at fair value on the date the guarantee is given. Financial guarantees are subsequently measured at the higher of the loss allowance and the amount initially recognized less the cumulative income recognized at the reporting date, and is included in “Other liabilities” in the consolidated statements of financial position. Any change in the loss allowance relating to financial guarantee contracts is included in “Impairment charges on financial assets” in the consolidated income statements.
Employee Benefits	Employee Benefits The Group operates various retirement benefit plans and other employee benefit plans. Retirement benefits The Group has defined benefit plans, such as defined benefit pension plans and lump-sum Defined benefit plans The liabilities and the assets recognized in the consolidated statements of financial position in respect of defined benefit plans are the present value of the defined benefit obligation less the fair value of plan assets. The present value of the defined benefit obligation is calculated annually by qualified actuaries. In calculating the present value of the defined benefit obligations, the related current service cost, and past service cost, the Group attributes the retirement benefits to years of service under the benefit formula. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using market yields of AA credit-rated corporate bonds that have terms to maturity approximating those of the related obligations. In cases where there is no deep market in corporate bonds with a sufficiently long maturity to match the estimated maturity of the benefit payments, the Group uses current market rates of the appropriate term to discount shorter term payments and estimates the discount rates for longer maturities by extrapolating current market rates along the yield curve. Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions in the year, and return on plan assets excluding interest income are recognized in other comprehensive income and are never reclassified to profit or loss. Past service costs are recognized immediately in the consolidated income statements. When the calculations above result in a benefit to the Group, the recognized asset is limited to the present value of any economic benefits available in the form of any refunds from the plan or reductions in future contributions to the plan (“asset ceiling”). An economic benefit is available to the Group if it is realizable during the life of the plan or on settlement of the plan obligations. Defined contribution plans Contributions to defined contribution plans are recognized as an expense in the consolidated income statements when they are due. Other long-term employee benefits The Group’s net obligation with respect to long-term employee benefits other than retirement benefits is the amount of future benefit that employees have earned in return for their service in the current and prior periods; that benefit is discounted to determine its present value and the fair value of any related assets is deducted. The discount rates are market yields of AA credit-rated corporate bonds that have terms to maturity approximating those of the related obligations. The calculation of obligations is performed using the projected unit credit method. Any actuarial gains or losses and past service costs are recognized in the consolidated income statements in the period in which they arise. Short-term employee benefits Short-term employee benefits, such as salaries, paid absences and other benefits are accounted for on an accrual basis over the period in which employees have provided services. Bonuses are recognized to the extent that the Group has a present obligation to its employees that can be measured reliably.
Income Tax	Income Tax Income tax expense comprises current and deferred taxes. Income tax expense is recognized in the consolidated income statements except for that related to items recognized directly in equity. In such case, the income tax expense is recognized in equity. Current tax is the expected tax payable or receivable on the taxable profit or loss for the fiscal year. Deferred taxes are recognized, using the balance sheet liability method, for temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. Deferred taxes are determined using tax rates (and laws) that have been enacted or substantially enacted by the end of the reporting period Deferred tax assets principally arise from tax losses carried forward, impairment of investment securities and loans, and the allowance for loan losses. Deferred taxes are not recognized for the following temporary differences: (a) the initial recognition of goodwill; (b) the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss; and (c) the temporary differences associated with investments in subsidiaries, associates, and joint ventures, when the parent investor is able to control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax assets relating to tax losses carried forward and deductible temporary differences are recognized, only to the extent that it is probable that future taxable profit will be available against which the tax losses carried forward and the deductible temporary differences can be utilized.
Debt and equity securities in issue	Debt and equity securities in issue On initial recognition, financial instruments issued by the Group are classified in accordance with the substance of the contractual agreement as financial liabilities where the contractual arrangement results in the Group having an obligation to either deliver cash or another financial asset to the holder, or to satisfy the obligation other than by delivering a fixed number of equity shares in exchange for a fixed amount of cash or another financial asset. The instruments or their components are classified as equity where they do not meet the definition of a liability and show evidence of a residual interest in the entity’s assets after deducting all of its liabilities. Compound financial instruments that contain both liability and equity elements are accounted for separately with the equity component being assigned the residual amount after deducting from the entire value of the compound financial instrument the fair value of the liability component which has been determined separately.
Shareholders' Equity	Shareholders’ Equity Stock issuance costs Incremental costs directly attributable to the issuance of new shares or options including those issued as a result of a business combination transaction are deducted from the proceeds and shown in equity, net of tax. Dividends on common stock and preferred stock Dividends on common stock and preferred stock are recognized in equity in the period in which they are approved by the shareholders. Dividends for the fiscal year that are declared after the reporting period are described in Note 41 “Dividends Per Share.” Treasury stock Where the Company or any other member of the Group companies purchase the Company’s common or preferred stock, the consideration paid is deducted from equity as treasury stock until they are cancelled or sold. No gain or loss is recognized on the purchase, sale, or cancellation of the Company’s own equity instruments and the consideration paid or received is recognized in equity.
Interest Income and Expense	Interest Income and Expense Interest income and expense for all financial instruments, except for those The effective interest method is a method of calculating the amortized cost of a financial asset or a financial liability and of allocating the interest income or interest expense over the relevant period. The effective interest rate is the rate that discounts the estimated future cash payments or receipts through the expected life of the financial instrument or, when appropriate, a shorter period to the gross carrying amount of a financial asset or to the amortized cost of a financial liability. When calculating the effective interest rate, the Group estimates cash flows, considering the contractual terms of the financial instrument but not including ECL. The calculation includes fees paid or received between parties to the contract that are an integral part of the effective interest rate of the financial instrument, transaction costs and other premiums or discounts. The effective interest method is used for calculating interest income by applying the effective interest rate to the gross carrying amount of a financial asset. However, for credit-impaired financial assets subsequent to initial recognition, interest income is calculated by applying the effective interest rate to the amortized cost of the financial assets.
Fee and Commission Income	Fee and Commission Income The Group recognizes fee and commission income in accordance with the five-step model. This model requires the Group to (i) identify the contract with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. Fee and commission income arises from a diverse range of services that the Group provides to its customers. Fee and commission income can be divided into two categories: fee and commission income from transaction services which is recognized at the point in time when the transaction takes place, and fee and commission income from services which is recognized over the time as the services are provided. Fee and commission income from transaction services includes fees on credit card business, fees and commissions on the securities business, underwriting fees, brokerage fees, investment trusts sales commissions, fees on funds transfer and collection services, loan syndication fees for arranging a loan and fee and commission income from other services. Fee and commission income from services that are provided over a period of time includes fiduciary fees, investment fund management fees, loan commitments fees from which specific lending is unlikely to be drawn down and fee and commission income from other services.
Net Trading Income	Net Trading Income Net trading income consists of margins made on market-making and customer business, as well as changes in fair value of trading assets and liabilities and derivative financial instruments, caused by movements in interest rates, exchange rates, equity prices and other market variables. It also includes net interest and dividend income on trading assets and liabilities.
Net Income (Loss) from Financial Assets and Liabilities at Fair Value through Profit or Loss	Net Income (Loss) from Financial Assets and Liabilities at Fair Value through Profit or Loss Net income (loss) from financial assets and liabilities at fair value through profit or loss includes all gains and losses arising from changes in the fair value of financial assets mandatorily measured at FVPL other than trading assets and derivative financial instruments, disposal of such assets, and interest and dividend income on these financial assets. It also includes gains and losses arising from changes in the fair values of financial liabilities designated at FVPL except for the effects of changes in their own credit risk, gains or losses arising from the derecognition and interest expense on these financial liabilities.
Net Investment Income	Net Investment Income Net investment income includes gains and losses on the disposal of debt instruments
Earnings Per Share	Earnings Per Share The Group presents basic and diluted earnings per share (“EPS”) data for its common stock. Basic EPS is calculated by dividing the profit or loss attributable to common shareholders of the Group by the weighted average number of common stock outstanding during the period. Diluted EPS is determined by adjusting the profit or loss attributable to common shareholders and the weighted average number of common stock outstanding for the effects of all dilutive potential common stock including share options and other convertible instruments.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Group is currently assessing the impact of the following standards, amendments to standards, and interpretations that are not yet effective and have not been early adopted: Sale or Contribution of Assets between an Investor and its Associate or Joint Venture (Amendments to IFRS 10 and IAS 28) In September 2014, the IASB issued the narrow-scope amendments to IFRS 10 and IAS 28 “Investments in Associates and Joint Ventures” to address an acknowledged inconsistency between the requirements in IFRS 10 and those in IAS 28, in dealing with the sale or contribution of assets between an investor and its associate or joint venture. The effective date of applying the amendments was January 1, 2016 when they were originally issued, however, in December 2015, the IASB issued Effective Date of Amendments to IFRS 10 and IAS 28 Reference to the Conceptual Framework (Amendments to IFRS 3) In May 2020, the IASB issued narrow-scope amendments to IFRS 3 “Business Combinations” to update a reference in IFRS 3 to the “Conceptual Framework for Financial Reporting” without changing the accounting requirements for business combinations. The amendments are effective for annual periods beginning on or after January 1, 2022 and are not expected to have a material impact on the Group’s consolidated financial statements. Property, Plant and Equipment: Proceeds before Intended Use (Amendments to IAS 16) In May 2020, the IASB issued narrow-scope amendments to IAS 16 “Property, Plant and Equipment.” The amendments prohibit an entity from deducting from the cost of property, plant and equipment amounts received from selling items produced while the entity is preparing the asset for its intended use. Instead, an entity will recognize such sales proceeds and related cost in profit or loss. The amendments are effective for annual periods beginning on or after January 1, 2022 and are not expected to have a material impact on the Group’s consolidated financial statements. Onerous Contracts: Cost of Fulfilling a Contract (Amendments to IAS 37) In May 2020, the IASB issued narrow-scope amendments to IAS 37 “Provisions, Contingent Liabilities and Contingent Assets” to specify which costs an entity includes when assessing whether a contract will be loss-making. The amendments are effective for annual periods beginning on or after January 1, 2022 and are not expected to have a material impact on the Group’s consolidated financial statements. Annual Improvements to IFRSs 2018–2020 In May 2020, the IASB issued Annual Improvements to IFRSs 2018-2020, which is amendments to IFRS 1 “First-time Adoption of International Financial Reporting Standards,” IFRS 9, IAS 41 “Agriculture” and the “Illustrative Examples” accompanying IFRS 16 “Leases.” These are minor amendments that clarify, simplify or remove redundant wordings in the standards. The amendments are effective for annual periods beginning on or after January 1, 2022 and are not expected to have a material impact on the Group’s consolidated financial statements. IFRS 17 “Insurance Contracts” In May 2017, the IASB published IFRS 17 “Insurance Contracts,” which establishes principles for the recognition, measurement, presentation and disclosure of insurance contracts, replacing IFRS 4 “Insurance Contracts.” IFRS 4 provided entities dispensation to carry on accounting for insurance contracts using national accounting standards, resulting in a multitude of different approaches. IFRS 17 requires all insurance contracts to be accounted for in a consistent manner. Insurance obligations will be accounted for by using present values instead of historical cost. In June 2020, the IASB issued amendments to IFRS 17 to help entities implement the standard and make it easier for them to explain their financial performance. The fundamental principles introduced when the IASB first issued IFRS 17 in May 2017 remain unaffected. The mandatory effective date of applying IFRS 17 was January 1, 2021 when it was originally issued but deferred to annual periods beginning on or after January 1, 2023. The Group is currently evaluating the potential impact that the adoption of the standard will have on its consolidated financial statements. Classification of Liabilities as Current or Non-current In January 2020, the IASB issued narrow-scope amendments to IAS 1 “Presentation of Financial Statements” to clarify how to classify debt and other liabilities as current or non-current. non-current. Disclosure of Accounting Policies (Amendments to IAS 1 and IFRS Practice Statement 2) In February 2021, the IASB issued narrow-scope amendments to IAS 1 and IFRS Practice Statement 2 “Making Materiality Judgements” to support entities improve accounting policy disclosures for users of financial statements. The amendments to IAS 1 require entities to disclose their material accounting policy information rather than their significant accounting policies. The amendments to IFRS Practice Statement 2 provide guidance on how to apply the concept of materiality to accounting policy disclosures. The amendments are effective for annual periods beginning on or after January 1 Definition of Accounting Estimates (Amendments to IAS 8) In February 2021, the IASB issued narrow-scope amendments to IAS 8 “Accounting Policies, Changes in Accounting Estimates and Errors.” The amendments introduce the definition of accounting estimates and clarify how entities should distinguish changes in accounting policies from changes in accounting estimates. The amendments are effective for annual periods 1 Deferred Tax related to Assets and Liabilities arising from a Single Transaction (Amendments to IAS 12) In May 2021, the IASB issued narrow-scope amendments to IAS 12 “Income Taxes” to specify how entities should account for deferred tax on transactions such as leases and decommissioning obligations. The aim of the amendments is to reduce diversity in the reporting of deferred tax on such transactions. The amendments are effective for annual periods beginning on or after January 1, 2023. The Group is currently evaluating the potential impact that the adoption of the standard will have on its consolidated financial statements. Initial Application of IFRS 17 and IFRS 9—Comparative Information (Amendment to IFRS 17) In December 2021, the IASB issued a narrow-scope amendment to the transition requirements in IFRS 17 to help entities avoid temporary accounting mismatches between financial assets and insurance contract liabilities caused by the different transition requirements between IFRS 17 and IFRS 9. The amendment is effective for annual periods beginning on or after January 1, 2023. The Group is currently evaluating the potential impact that the adoption of the amendment will have on its consolidated financial statements.

(2) Transfers between levels of the fair value hierarchy are deemed to have occurred at the beginning of the period. For the fiscal year ended March 31, 2022 , primarily due to an increase in observability of certain financial liabilities designated at fair value through profit or loss. On the other hand, for the fiscal year ended March 31, 2021, those amounted to ¥27,377 million primarily due to an increase in observability of certain investment funds. (3) Derivatives embedded in financial liabilities, except for financial liabilities designated at fair value through profit or loss, are separately accounted for, but presented together with the host contract in the consolidated statements of financial position. In these tables, the separated embedded derivatives whose host contracts are carried at amortized cost are presented within others. Although the separated embedded derivatives may have a positive or a negative fair value, they have been presented in these tables as liabilities to be consistent with the host contract.

(2) The Group has determined that the net asset value represents fair values of certain investment funds. (3) Fair values of certain equity instruments such as unlisted stocks are estimated on the basis of an analysis of the investee’s financial position and results, risk profile, prospects and other factors. A range of key inputs is not provided in these tables as it is not practical to do so given the nature of such valuation techniques. (4) Derivatives embedded in financial liabilities, except for financial liabilities designated at fair value through profit or loss, are separately accounted for, but presented together with the host contract in the consolidated statements of financial position. In these tables, the separated embedded derivatives whose host contracts are carried at amortized cost are presented within others. Although the separated embedded derivatives may have a positive or a negative fair value, they have been presented in these tables as liabilities to be consistent with the host contract.
Impact of Valuation Sensitivity	The fair value of certain financial assets and liabilities are measured using valuation techniques based on inputs such as prices and rates that are not observable in the market. The following tables present the impact of the valuation sensitivity, if these inputs fluctuate to the extent deemed reasonable and the volatility of such inputs has a significant impact on the fair value.

Sensitivity of embedded derivatives related to these transactions is presented as derivative financial instruments or financial assets at fair value through profit or loss, according to the presentation of the financial instruments arising from these transactions. (2) Derivatives embedded in financial liabilities, except for financial liabilities designated at fair value through profit or loss, are separately accounted for, but presented together with the host contract in the consolidated statements of financial position. In these tables, the separated embedded derivatives whose host contracts are carried at amortized cost are presented within others. Although the separated embedded derivatives may have a positive or a negative fair value, they have been presented in these tables as liabilities to be consistent with the host contract.
Financial Assets and Liabilities Not Carried at Fair Value	The tables below present the carrying amounts and fair values by level within the fair value hierarchy, as described in “Financial Assets and Liabilities Carried at Fair Value—Fair Value Hierarchy,” of financial assets and liabilities not carried at fair value on the Group’s consolidated statements of financial position at March 31, 2022 and 2021. They do not include the carrying amounts and fair values of financial assets and liabilities whose carrying amounts are reasonable approximations of fair values.

The fair values of debt instruments at amortized cost are determined using quoted prices in active markets or observable inputs other than quoted prices in active markets. b. (i) The carrying amounts of loans with no specified repayment dates represent a reasonable estimate of fair value, considering the nature of these financial instruments. (ii) Short-term financial assets: The carrying amounts represent a reasonable estimate of fair value. (iii) Long-term financial assets: Except for impaired loans and advances, the fair values are mostly determined using discounted cash flow models taking into account certain factors including counterparties’ credit ratings, pledged collateral, and market interest rates. The fair values of impaired loans and advances are generally determined by discounting the estimated future cash flows over the time period they are expected to be recovered, and may be based on the appraisal value of underlying collateral as appropriate. c. Note that some of the financial liabilities in this category include embedded derivatives, which are separately accounted for, but presented together with the host contract. (i) The carrying amounts of demand deposits and deposits without maturity represent a reasonable estimate of fair value, considering the nature of these financial instruments. (ii) Short-term financial liabilities: The carrying amounts represent a reasonable estimate of fair value. (iii) Long-term financial liabilities: The fair values are, in principle, based on the present values of future cash flows calculated using the funding costs for the remaining maturities. The fair values of debt securities in issue are based on a price quoted by a third party, such as a pricing service or broker, or the present values of future cash flows calculated using the rate derived from yields of bonds issued by SMFG, SMBC and other subsidiaries and publicly offered subordinated bonds published by securities firms. (iv) The carrying amounts and fair values of lease liabilities are not included in these tables.
