Report on Review of Condensed Consolidated Interim Financial Statements

(English Translation of a Report Originally Issued in Korean)

To the Shareholders and the Board of Directors of

KB Financial Group Inc.

Reviewed Financial Statements

We have reviewed the accompanying condensed consolidated interim financial statements of KB Financial Group Inc. and its subsidiaries (collectively referred to as the “Group”). These condensed consolidated interim financial statements consist of the consolidated interim statement of financial position of the Group as at June 30, 2024, and the related consolidated interim statements of comprehensive income for the three-month and six month periods ended June 30, 2024 and 2023, and consolidated interim statements of changes in equity and cash flows for the six-month periods ended June 30, 2024 and 2023, and material accounting policy information and other selected explanatory notes, expressed in Korean Won.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and presentation of these condensed consolidated interim financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“Korean IFRS”) No. 1034 Interim Financial Reporting, and for such internal control as management determines is necessary to enable the preparation of condensed consolidated interim financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express a conclusion on these condensed consolidated interim financial statements based on our review.

We conducted our review in accordance with quarterly or semi-annual review standards established by the Securities and Futures Commission of the Republic of Korea. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Korean Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe the accompanying condensed consolidated interim financial statements are not prepared, in all material respects, in accordance with Korean IFRS No. 1034 Interim Financial Reporting.

1

Other Matters

We have audited the consolidated statement of financial position of the Group as at December 31, 2023, and the related consolidated statements of comprehensive income, changes in equity and cash flows for the year then ended, not presented herein, in accordance with Korean Standards on Auditing. We expressed an unqualified opinion on those financial statements in our audit report dated March 6, 2024. The consolidated statement of financial position as at December 31, 2023, presented herein for comparative purposes, is consistent, in all material respects, with the above audited statement of financial position as at December 31, 2023.

Review standards and their application in practice vary among countries. The procedures and practices used in the Republic of Korea to review such financial statements may differ from those generally accepted and applied in other countries.

2. Basis of Preparation

2.1 Application of Korean IFRS

The Group maintains its accounting records in Korean won and prepares statutory consolidated financial statements in the Korean language (Hangul) in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“Korean IFRS”). The accompanying consolidated financial statements have been translated into English from the Korean language consolidated financial statements.

The consolidated financial statements of the Group have been prepared in accordance with Korean IFRS. Korean IFRS are the standards and related interpretations issued by the International Accounting Standards Board (“IASB”) that have been adopted by the Republic of Korea.

The preparation of the consolidated financial statements requires the use of certain critical accounting estimates. Management also needs to exercise judgment in applying the Group’s accounting policies. The areas that require a more complex and higher level of judgment or areas that require significant assumptions and estimations are disclosed in Note 2.4.

The Group’s condensed consolidated interim financial statements for the six-month period ended June 30, 2024, have been prepared in accordance with Korean IFRS No.1034 Interim Financial Reporting and contain less information than is required in annual consolidated financial statements. Selected explanatory notes include descriptions of transactions or events that are significant in understanding change in financial position and financial performance of the Group since the end of the previous annual reporting period. These condensed consolidated interim financial statements have been prepared in accordance with Korean IFRS which is effective or early adopted as of June 30, 2024.

2.1.1 The Group has applied the following new and amended standards for the first time for its annual reporting period commencing January 1, 2024.

- Amendment of Korean IFRS No.1001 “Presentation of Financial Statements”—Classification of Liabilities into Current and Non-Current and Non-current Liabilities with Covenants

Liabilities are classified as current or non-current based on their substantive rights existing at the end of the reporting period, without considering the possibility of exercising the right to delay the payment or management’s expectations. Also, if the transfer of equity instruments is included in the payment of liabilities, it is excluded if the option to pay with equity instruments is recognized separately from the liability in a compound financial instrument and meets the definition of equity instruments. These amendments do not have a significant impact on the financial statements.

- Amendment of Korean IFRS No.1007 “Statement of Cash Flows” and No.1107 “Financial Instruments: Disclosures” – Disclosure of Supplier Finance Arrangements

The amendments require disclosure of the effects of supplier finance arrangements on the Group’s liabilities, cash flows and exposure to liquidity risk. These amendments do not have a significant impact on the financial statements.

2.1.1 The Group has applied the following new and amended standards for the first time for its annual reporting period commencing January 1, 2024. (cont’d)

- Amendment of Korean IFRS No.1116 “Leases”—Lease Liability in a Sale and Leaseback

The amendments require a seller-lessee to subsequently measure lease liabilities arising from a leaseback in a way that it does not recognize any amount of the gain or loss that relates to the right of use it retains. These amendments do not have a significant impact on the financial statements.

- Amendment of Korean IFRS No.1001 “Presentation of Financial Statements” – Disclosure of Virtual Asset

The amendments require additional disclosure for virtual assets held by the Group, virtual assets entrusted by customers to the Group, and the issuance and transfer of virtual assets. These amendments do not have a significant impact on the financial statements.

2.1.2 The following are the accounting standards that have been established or announced but have not yet been implemented, which the Group has not applied

- Amendment of Korean IFRS No.1021 “The Effects of Changes in Foreign Exchange Rates” and Korean IFRS No.1101 “First-time Adoption of International Financial Reporting Standards”—Lack of exchangeability

The amendments require the Group to determine a spot exchange rate when exchangeability is lacking, and to disclose information on the nature and financial effects of the currency not being exchangeable into the other currency, the spot exchange rate(s) used, the estimation process, and the risks to which the Group is exposed. This amendment will be applied to the financial statements for the accounting year beginning on or after January 1, 2025. These amendments do not have a significant impact on the financial statements.

2.1.3 Restatement of financial statements for the six-month period ended June 30, 2023 for the application of “Variable Fee Approach”

The Group has initially applied on December 31, 2023, guidelines for calculating policy reserves and recognizing revenue for insurance companies announced by Financial Supervisory Service (FSS) in South Korea. Under these guidelines, the Group applied the “Variable Fee Approach” to the financial statements as of December 31, 2023 and year then ended. The effects of this change have been retrospectively applied to the comparative disclosure for past periods as a “change in accounting policy.” The condensed consolidated interim financial statements as of June 30, 2023 and the six-month period then ended, presented herein for the comparative purpose, have been restated to reflect the impact of this retrospective application. The effect of the change in accounting policy to the previous consolidated financial statements is as follows.

2.2 Measurement Basis

The consolidated financial statements have been prepared based on the historical cost accounting model unless otherwise specified.

2.3 Functional and Presentation Currency

Items included in the financial statements of each entity of the Group are measured using the currency of the primary economic environment in which the entity operates (“functional currency“). The consolidated financial statements are presented in Korean won, which is the Parent Company‘s functional and presentation currency.

2.4 Critical Accounting Estimates

The Group applies accounting policies and uses judgements, accounting estimates and assumptions that may have a significant impact on the assets (liabilities) and incomes (expenses). Management’s estimates of outcomes may differ from actual outcomes if management’s estimates and assumptions based on management’s best judgment at the reporting date are different from the actual environment.

Estimates and underlying assumptions are continually evaluated, and changes in accounting estimates are recognized in the period in which the estimates are changed and in any future periods affected.

Uncertainties in estimates and assumptions with significant risks used in the preparation of these condensed consolidated interim financial statements are the same as 2023 financial statements, except for the method of estimating income tax expense.

3. Material Accounting Policies

The material accounting policies and calculation methods applied in the preparation of these consolidated interim financial statements are the same as those applied to the consolidated financial statements for the year ended December 31, 2023, except for the impact of changes due to adopting new and amended standards and interpretations described in Note 2.1 and below paragraph.

The Group is subject to Pillar2 income taxes, and has applied a temporary exemption provision regarding the recognition and disclosure of deferred taxes related to the Pillar 2 rules. Income tax expense for the interim period is measured applying the expected average annual income tax rate applicable on expected total annual income.

4. Financial Risk Management

4.1 Summary

4.1.1 Overview of financial risk management policy

The financial risks that the Group is exposed to are credit risk, market risk, liquidity risk, operational risk, and others.

This note regarding financial risk management provides information about the risks that the Group is exposed to and about its objectives, policies, risk assessment and management procedures, and capital management. Additional quantitative information is disclosed throughout the consolidated financial statements.

The Group’s risk management system focuses on efficiently supporting long-term strategy and management decisions of the Group by increasing risk transparency, preventing risk transfer between subsidiaries and preemptive response to rapidly changing financial environments. Credit risk, market risk, operational risk, interest rate risk, insurance risk, liquidity risk, credit concentration risk, strategy risk, and reputation risk are recognized as the Group’s significant risks and measured and managed by quantifying them in the form of internal capital or Value at Risk (“VaR”) using statistical methods.

4.1.2 Risk management organization

4.1.2.1 Risk Management Committee

The Risk Management Committee, as the ultimate decision-making body, deals with risk-related issues, such as establishing risk management strategies in accordance with the strategic direction determined by the Board of Directors, determining the affordable level of risk appetite, reviewing the level of risk and the status of risk management activities, approving the application of risk management systems, methodologies, and major improvements, and establishing and approving risk management policies and procedures to timely recognize, measure, monitor, and control risks arising from various transactions by the Group.

4.1.2.2 Risk Management Council

The Risk Management Council is responsible for consulting on matters delegated by the Risk Management Committee and requests for review by the Management Executive Committee, consulting on details of each subsidiary’s risk management policies and procedures, monitoring the Group’s risk management status, and establishing and implementing necessary measures.

4.2 Credit Risk

4.2.1 Overview of credit risk

Credit risk is the risk of loss from the portfolio of assets held due to the counterparty’s default, breach of contract, and deterioration of credit quality. For risk management purposes, the Group manages all factors of credit risk exposure, such as default risk of individual borrowers, country risk, and risk of specific sectors in an integrated way.

4.2.2 Credit risk management

The Group measures the expected loss and internal capital for the assets subject to credit risk management, including on-balance and off-balance assets, and uses them as management indicators. The Group allocates and manages credit risk internal capital limits.

In addition, to prevent excessive concentration of exposures by borrower and industry, the total exposure limit at the Group level is introduced, applied, and managed to control the credit concentration risk.

All of the Kookmin Bank’s loan customers (individuals and corporates) are assigned a credit rating and managed by a comprehensive internal credit evaluation system. For individuals, the credit rating is evaluated by utilizing personal information, income and job information, asset information, and bank transaction information. For corporates, the credit rating is evaluated by analyzing and utilizing financial and non-financial information which measures current and future corporate value and ability to repay the debt. Also, the extent to which corporates have the ability to meet debt obligations is comprehensively considered.

The credit rating, once assigned, serves as the fundamental instrument in Kookmin Bank’s credit risk management, and is applied in a wide range of credit risk management processes, including credit approval, credit limit management, loan pricing, and assessment of allowances for credit losses. For corporates, Kookmin Bank conducts a regular credit evaluation at least once a year, and the review and supervision departments regularly validate the adequacy of credit ratings to manage credit risks.

KB Kookmin Card Co., Ltd.’s credit scoring system is divided into Application Scoring System (“ASS”) and Behavior Scoring System (“BSS”). For applications that meet the eligibility criteria for card issuance, the card will be issued only if the ASS credit rating is above the standard. KB Kookmin Card Co., Ltd.’s internal information, external information from the credit bureau company and others, and personal information on the application are used to calculate the ASS credit rating. The BSS, which is recalculated on a weekly basis, predicts the delinquency probability of cardholders, and utilizes it to monitor cardholders and portfolio risk.

In order to establish a credit risk management system, the Group manages credit risk by forming a separate risk management organization. In particular, independently of the Sales Group, the Credit Management & Analysis Group of Kookmin Bank, a subsidiary, is in charge of loan policy, loan system, credit rating, credit analysis, follow-up management, and corporate restructuring. The Risk Management Group of Kookmin Bank is responsible for establishing policies on credit risk management, measuring and limiting internal capital of credit risk, setting credit limits, credit review, and verification of credit rating models.

4.2.4 Credit risk of loans

The Group maintains allowances for loan losses associated with credit risk of loans to manage its credit risk.

The Group assesses expected credit losses and recognizes loss allowances of financial assets at amortized cost and financial assets at fair value through other comprehensive income. Financial assets at fair value through profit or loss are excluded. Expected credit losses are a probability-weighted estimate of possible credit losses occurring in a certain range by reflecting reasonable and supportable information that is reasonably available at the end of the reporting period without undue cost or effort, including information about past events, current conditions, and forecasts of future economic conditions. The Group measures the expected credit losses of loans classified as financial assets at amortized cost, by deducting allowances for credit losses. The expected credit losses of loans classified as financial assets at fair value through other comprehensive income are presented in other comprehensive income in the consolidated financial statements.

4.3 Liquidity Risk

4.3.1 Overview of liquidity risk

Liquidity risk is a risk that the Group becomes insolvent due to the mismatch between the inflow and outflow of funds, unexpected cash outflows, or a risk of loss due to financing funds at a high interest rate or disposing of securities at an unfavorable price due to lack of available funds. The Group manages its liquidity risk through analysis of the contractual maturity of interest-bearing assets and liabilities, assets and liabilities related to the other inflows and outflows of funds, and off-balance sheet items related to the inflows and outflows of funds such as currency derivative instruments and others.

4.3.2 Liquidity risk management and indicator

The liquidity risk is managed by risk management policies and liquidity risk management guidelines set forth in these policies that apply to all risk management policies and procedures that may arise throughout the overall business of the Group.

The Group calculates and manages liquidity ratio and others for all transactions and off-balance transactions related to liquidity, that affect the cash flows in Korean won and foreign currency funds raised and operated for the management of liquidity risks and periodically reports them to the Risk Management Committee.

4.3.3 Analysis of remaining contractual maturity of financial liabilities

The cash flows disclosed in the maturity analysis are undiscounted contractual amounts including principal and future interest payments; as such, amounts in the table below do not match with those in the consolidated statements of financial position which are based on discounted cash flows. The future interest payments for floating-rate liabilities are calculated on the assumption that the current interest rate is the same until maturity.

¹  Financial liabilities measured or designated at fair value through profit or loss and derivatives held for trading are not managed by contractual maturity because they are expected to be traded or redeemed before maturity. Therefore, the carrying amounts of those financial instruments are included in the ‘On demand’ category.

² Cash flows of derivatives held for hedging are shown at net amount of cash inflows and outflows by remaining contractual maturity.

³ Deposits that are contractually repayable on demand or on short notice are included in the ‘On demand’ category.

⁴ Commitments are included in the ‘On demand’ category because payments can be requested at any time.

⁵ Cash flows under financial guarantee contracts are classified based on the earliest period that the contract can be executed.

4.4 Market Risk

4.4.1 Concept

Market risk refers to risks that can result in losses due to changes in market factors such as interest rate, stock price, and foreign exchange rate, etc., which arise from securities, derivatives, and others. The most significant risks associated with trading positions are interest rate risk, currency risk, and additional risks include stock price risk. The non-trading position is also exposed to interest rate risk. The Group manages the market risks by dividing them into those arising from the trading position and those arising from the non-trading position.

4.4.2 Risk management

The Group sets and monitors internal capital limits for market risk and interest rate risk to manage the risks of trading and non-trading positions. In order to manage market risk efficiently, the Group maintains risk management systems and procedures such as trading policies and procedures, market risk management guidelines for trading positions, and interest rate risk management guidelines for non-trading positions. The entire process is carried out through consultation with the Risk Management Council and approval by the Risk Management Committee of the Group. However, insurance companies that are engaged in the insurance business are not subject to these guidelines and are monitored by setting internal capital limits for market risk and interest rate risk based on K-ICS.

In the case of Kookmin Bank, a major subsidiary, the Risk Management Council establishes and enforces overall market risk management policies for market risk management and decides to establish position limits, loss limits, VaR limits, and approves non-standard new products. In addition, the Market Risk Management Subcommittee, chaired by Chief Risk Officer (“CRO”), is a practical decision-making body for market risk management and determines position limits, loss limits, VaR limits, sensitivity limits, and scenario loss limits for each department of the business group.

Kookmin Bank’s Asset-Liability Management Committee (“ALCO”) determines interest rate and commission operating standards and Asset Liability Management (“ALM”) operation policies and enacts and revises relevant guidelines. The Risk Management Committee and the Risk Management Council monitor the establishment and enforcement of ALM risk management policies and enact and revise ALM risk management guidelines. Interest rate risk limits are set based on future asset and liability positions and expected interest rate volatility, which reflect annual business plans. The Financial Planning Department and the Risk Management Department regularly measure and monitor interest rate risk and report the status and limit of interest rate risk including changes in Economic Value of Equity (“ΔEVE”), changes in Net Interest Income (“ΔNII”), and duration gap to the ALCO and the Risk Management Council on a monthly basis, and to the Risk Management Committee on a quarterly basis. To ensure the adequacy of interest rate risk and liquidity risk management, the Risk Management Department assigns the limits, monitors and reviews the procedures and tasks of ALM operations conducted by the ALM department, and reports related matters to the management independently.

Kookmin Bank is closely monitoring the outputs of various industry groups and markets that manage the transition to the new interest rate benchmark, including announcements by regulation authority and various consultative bodies related to the transition to alternative interest rate. In response to these announcements, Kookmin Bank has completed most of the transition and replacement plans according to LIBOR transition programs and plans consisting of major business areas such as finance, accounting, tax, legal, IT, and risk. The program is under the control of the CFO and related matters are reported to the Board of Directors and consultative bodies with senior management as members. Kookmin Bank continues its efforts as a market participant to actively express opinions so that the index interest rate benchmark reform can be carried out in the direction of minimizing the financial and non-financial impacts and operational risks and minimizing confusion among stakeholders.

4.5 Operational Risk

4.5.1 Concept

Operational risk of the Group refers to the risk of loss that may occur due to improper or incorrect internal procedures, personnel, systems or external events. Operational risk management plays a role in enhancing the stability and soundness of financial institutions by managing the appropriate level of capital and supplementing the internal control system.

4.5.2 Risk management

The purpose of operational risk management is not only to comply with supervisory and regulatory requirements, but also to spread risk management culture, strengthen internal control, improve processes, and provide timely feedback to management and all employees. The Parent Company manages the Group’s overall operational risk, and each subsidiary establishes and implements operational risk management policies according to its own risk level and implements and operates related systems. The Group Risk Management Committee establishes and allocates risk capital of operational risk for each subsidiary, and subsidiaries manage operational risks at an appropriate level within the allocated risk capital.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The Group discloses the fair value of each class of assets and liabilities in a way that permits it to be compared with its carrying amount at the end of each reporting period. The best evidence of fair value of financial instruments is a quoted price in an active market.

6.1.1 Carrying amount and fair value of financial assets and liabilities by category as of June 30, 2024 and December 31, 2023, are as follows: (cont’d)

Methods of determining fair value of financial instruments are as follows:

Cash and due from financial institutions	Fair value of cash is same as carrying amount. Carrying amount of demand deposit and settlement deposit is a reasonable approximation of fair value because these financial instruments do not have a fixed maturity and are receivable on demand. Fair value of general deposit is measured using Discounted Cash Flow (“DCF”) Model.
Securities	Fair value of securities and others that are traded in an active market is determined using the quoted prices. If there is no quoted price, fair value is determined using external professional valuation institutions. The institutions use one or more valuation techniques that are deemed appropriate considering the characteristics of the financial instruments among DCF Model, Free Cash Flow to Equity Model, Comparable Company Analysis, Dividend Discount Model, Risk Adjusted Discount Rate Method, and Net Asset Value Method.
Loans	Fair value of loans is determined using DCF Model discounting the expected cash flows, which are contractual cash flows adjusted by the expected prepayment rate, at an appropriate discount rate.
Derivatives and financial instruments at fair value through profit or loss	Fair value of exchange traded derivatives is determined using quoted price in an active market, and fair value of OTC derivatives is determined using valuation techniques. The Group uses internally developed valuation models that are widely used by market participants to determine fair value of plain vanilla OTC derivatives including options, interest rate swaps, and currency swaps, based on observable market parameters. However, some complex financial instruments are valued using appropriate models developed from generally accepted market valuation models including Finite Difference Method (“FDM”), MonteCarlo Simulation, Black-Scholes Model, Hull-white Model, Closed Form, and Tree Model or valuation results from independent external professional valuation institutions.
Deposits	Carrying amount of demand deposits is a reasonable approximation of fair value because they do not have a fixed maturity and are payable on demand. Fair value of time deposits is determined using DCF Model discounting the expected cash flows, which are contractual cash flows adjusted by the expected prepayment rate, at an appropriate discount rate.
Borrowings	Carrying amount of overdrafts in foreign currency is a reasonable approximation of fair value because they do not have a fixed maturity and are payable on demand. Fair value of other borrowings is determined using DCF Model.
Debentures	Fair value is determined using valuation results of external professional valuation institutions, which are calculated using market inputs.
Other financial assets and other financial liabilities	Carrying amount is a reasonable approximation of fair value because other financial assets and other financial liabilities are temporary accounts used for other various transactions and their maturities are relatively short or not defined.

6.1.2 Fair value hierarchy

The Group believes that valuation techniques used for measuring the fair value of financial instruments are reasonable and that the fair value recognized in the consolidated statement of financial position is appropriate. However, the fair value of the financial instruments recognized in the consolidated statement of financial position may be different if other valuation techniques or assumptions are used. Additionally, as there are a variety of valuation techniques and assumptions used in measuring fair value, it may be difficult to reasonably compare the fair value with that of other financial institutions.

The Group classifies and discloses fair value of the financial instruments into the three fair value levels as follows:

Level 1: The fair values are based on quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity can access at the measurement date.

Level 2: The fair values are based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3: The fair values are based on unobservable inputs for the asset or liability.

The fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement. If an observable input requires an adjustment using an unobservable input and that adjustment results in a significantly higher or lower fair value measurement, the resulting measurement would be categorized within Level 3 of the fair value hierarchy.

6.2 Disclosure of Fair Value Hierarchy Level 3

6.2.1 Valuation policy and process of Level 3 fair value

The Group uses external, independent and qualified valuation service in addition to internal valuation models to determine the fair value of financial instruments at the end of every reporting period.

If the changes in situation and events which cause transfers between the fair value hierarchy level for a financial asset or liability occur, the Group’s policy is to recognize such transfers as having occurred at the beginning of the reporting period.

6.2.3.2 Sensitivity analysis of changes in unobservable inputs

Sensitivity analysis of financial instruments is performed to measure favorable and unfavorable changes in fair value of financial instruments which are affected by unobservable parameters, using a statistical technique. When the fair value is affected by more than one input parameter, the amounts represent the most favorable or most unfavorable outcome. Level 3 financial instruments subject to sensitivity analysis are (a) equity-related derivatives, currency-related derivatives, and interest rate related derivatives whose fair value changes are recognized in profit or loss, (b) financial liabilities designated at fair value through profit or loss, and (c) due from financial institutions, debt securities (including beneficiary certificates), equity securities, and loans whose fair value changes are recognized in profit or loss or other comprehensive income or loss. If the overlay approach according to Korean IFRS No. 1104 is applied, the fair value changes of financial assets at fair value through profit or loss are recognized as other comprehensive income.

Results of the sensitivity analysis of changes in unobservable inputs as of June 30, 2024 and December 31, 2023, are as follows:

(In millions of Korean won)	June 30, 2024

¹  For financial instruments at fair value through profit or loss, changes in fair value are calculated by shifting principal unobservable input parameters such as discount rate, recovery rate, liquidation value by ±1%p and volatility of underlying asset, growth rate by ±1%p or ±10% and correlation coefficient by ±10%.

²  For derivative financial instruments, changes in fair value are calculated by shifting principal unobservable input parameters such as price of underlying asset and volatility by ± 10%.

³  For equity securities, changes in fair value are calculated by shifting principal unobservable input parameters such as discount rate (-1%p~1%p) and growth rate (-1%p~1%p).

⁴  For beneficiary certificates, it is practically impossible to analyze sensitivity of changes in unobservable inputs. However, for beneficiary certificates whose underlying assets are real estates, changes in fair value are calculated by shifting rate of real estate price fluctuation by -1%p~1%p, and for beneficiary certificates whose underlying assets are equity investments, changes in fair value are calculated by shifting principal unobservable input parameters such as liquidation value by -1%p~1%p and discount rate by -1%p~1%p.

⁵  For loans, changes in fair value are calculated by shifting principal unobservable input parameters such as discount rate by -1%p~1%p.

6.2.4 Valuation gains and losses on transaction day

When the Group measures the fair value of OTC derivatives using inputs that are not based on observable market data, there could be a difference between the transaction price and the amount determined using that valuation technique. In these circumstances, the fair value of financial instruments is recognized as the transaction price, and the difference is not recognized in profit or loss but deferred and amortized using the straight-line method over the life of the financial instrument. When the fair value of the financial instruments is subsequently determined using observable market inputs, the remaining deferred amount is recognized in profit or loss.

Changes in deferred valuation gains and losses on transaction day for the six-month periods ended June 30, 2024 and 2023, are as follows:

(In millions of Korean won)	2024			2023
Balance at the beginning of the period	W	23,431		W	71,504
New transactions		28,940			62,086
Changes during the period		(42,666	)		(80,002	)
Balance at the end of the period	W	9,705		W	53,588

8. Derivative Financial Instruments and Hedge Accounting

The Group’s derivative operations focus on addressing the needs of the Group’s corporate clients to hedge their risk exposure and hedging the Group’s risk exposure that results from such client contracts. The Group also engages in derivative trading activities to hedge the interest rate risk and currency risk arising from the Group’s own assets and liabilities. In addition, the Group engages in proprietary trading of derivatives within the predetermined transaction limit.

The Group provides and trades a range of derivative financial instruments, including:

• Interest rate swaps relating to interest rate risk in Korean won

• Cross-currency swaps, forwards, and options relating to currency risk

• Stock index options linked with the Korea Composite Stock Price Index (“KOSPI”)

In particular, the Group applies fair value hedge accounting using interest rate swaps, currency forwards, and others to hedge the risk of changes in fair value due to the changes in interest rate and foreign exchange rate of structured debentures in Korean won, debentures in foreign currencies, structured deposits in foreign currencies, and others. The Group applies cash flow hedge accounting using interest rate swaps, currency swaps, and others to hedge the risk of changes in cash flows of floating rate debt securities in Korean won, borrowings in foreign currencies, group of loans measured at amortized cost, and others. In addition, the Group applies net investments in foreign operations hedge accounting by designating debentures in foreign currencies and cross currency forwards as hedging instruments to hedge the currency risk of net investments in foreign operations.

The net defined benefit liabilities recognized in the consolidated statement of financial position are calculated by the independent actuary in accordance with actuarial valuation method. The defined benefit obligation is calculated using the projected unit credit method. Assumptions based on market data and historical data such as discount rate, future salary increase rate, mortality, and consumer price index are used which are updated annually.

Actuarial assumptions may differ from actual results, due to changes in the market conditions, economic trends, and mortality trends which may affect net defined benefit liabilities and future payments.

28.2 Diluted Earnings per Share

Diluted earnings per share is calculated through increasing the weighted average number of ordinary shares outstanding by the weighted average number of additional ordinary shares that would have been outstanding assuming the conversion of all dilutive potential ordinary shares. The Group has dilutive potential ordinary shares such as stock grants and ordinary share exchange right of exchangeable bonds.

A calculation is done to determine the number of shares that could have been acquired at fair value (determined as the average market share price during the period) based on the monetary value of stock grants. The number of shares calculated above is compared with the number of shares that would have been issued assuming the settlement of stock grants.

Exchangeable bonds are included in potential ordinary shares from the exercisable date of the exchange right, and interest expense after tax for the period is added to profit for diluted earnings per share.

Company	Lawsuits	No. of cases	Amount		Description of the lawsuits	Status of the lawsuits
Kookmin Bank	Expropriation of long-term leasehold rights	1		347,300	Kookmin Bank invested assets entrusted by OO Asset Management Co., Ltd. in loans that are directly or indirectly collateralized by long-term leasehold rights of the building and the land (hereinafter referred to as “the real estate in this case”) of Union Station in Washington, D.C., the United States. The Plaintiff, who is the operator of the railway facility, filed this lawsuit against those concerned with the real estate in this case, including Kookmin Bank, to expropriate the real estate in this case and determine indemnity.	Kookmin Bank submitted the response letter and will proceed with the process in the future.
	Return of unjust enrichment	1		151,762	As MTS Bank, which was trading with Kookmin Bank through a foreign exchange account, was listed on the SDN (Specifically Designated Nationals) list of the Office of Foreign Assets Control (OFAC) under the U.S. Treasury Department, Kookmin Bank froze the foreign currency account in the name of MTS Bank. Accordingly, MTS Bank filed a lawsuit seeking the return of the account balance to the Moscow City Commercial Court in Russia.	Responding to local court trial schedule.
	Claim for damages	1		96,592	PT Bank KB Bukopin Tbk requested an auction of TMJ’s shares in order to collect the loan to TMJ (a distressed company); NKLI won the auction and then received a loan from the bank for the purpose of purchasing TMJ shares. NKLI’s intention was to take control over TMJ and launch mining business; however, NKLI was unable to take control and launch the business due to legal disputes with the bankruptcy trustee of TMJ and court-appointed mine management company, and also lost a lawsuit against the mine management company. As a result, NKLI filed a legal suit to PT Bank KB Bukopin Tbk stating that the bank’s recommendation to purchase TMJ’s shares was inappropriate since the bank did not intentionally share the legal issues and associated risks thereof.	A legal representative has been appointed to handle the case, and the first trial is in progress.

31.3 Other Matters (cont’d)

b) On April 7, 2023, Kookmin Bank entered into a new share subscription agreement with STIC Eugene Star Holdings Inc. (hereinafter referred to as “STIC”), under which STIC will acquire 31,900,000,000 shares at a price of IDR 3.19 trillion, which Kookmin Bank’s subsidiary, PT Bank KB Bukopin Tbk, issued. As a result of the agreement, Kookmin Bank will hold a call option to purchase the shares held by STIC, starting from 2 years and 6 months after the date of acquisition, for a period of 6 months. If Kookmin Bank does not exercise the call option during the designated period, STIC will have the right to sell the acquired shares back to the bank, also known as holding a put option right, within 1 year after the expiration of the call option exercise period.

c) Kookmin Bank is currently under investigation by the Fair-Trade Commission regarding the possibility of unfair joint actions by commercial banks. It is impossible to predict the outcome of the investigation.

d) As of June 30, 2024, KB Real Estate Trust Co., Ltd. may lend W 3,055,900 million to the trust accounts, which is part of the total project cost related to borrowing-type land trust contracts (including maintenance projects). Whether or not KB Real Estate Trust Co., Ltd. will lend to a trust account is not an unconditional payment obligation, and it is judged by considering all matters such as the fund balance plan of its own account and trust business.

e) KB Real Estate Trust Co., Ltd. is carrying out the completion guarantee management-type land trust project (50 cases, including Gonghang-dong Airport City, excluding construction project), that bears responsibility for the completion guarantee when the construction company fails to fulfill responsibility for the completion guarantee and bears responsibility for compensating for damages to lending financial institutions as of June 30, 2024. The total credit line of PF loan related to the completion guarantee management-type land trust project is W 4,348,600 million, and the used credit line is W 3,193,100 million as of June 30, 2024. The amount of compensation for damages charged to KB Real Estate Trust Co., Ltd. is measured after determining whether the damage occurred due to the company’s failure to fulfill the completion guarantee. Since the amount of loss cannot be measured reliably, this impact is not reflected in the Financial statements as of and for the six-month periods ended June 30, 2024. The Group plans to continuously monitor the process progress at each business site.
