Independent Auditor’s Report

(English Translation of a Report Originally Issued in Korean)

To the Board of Directors and Shareholders of Kookmin Bank

Opinion

We have audited the separate financial statements of Kookmin Bank(the “Company”) which comprise the separate statements of financial position as at December 31, 2025 and 2024, and the separate statements of comprehensive income, separate statements of changes in equity and separate statements of cash flows for the years then ended, and notes to the separate financial statements, including material accounting policy information.

In our opinion, the accompanying separate financial statements present fairly, in all material respects, the separate financial position of Kookmin Bank as at December 31, 2025 and 2024, and its separate financial performance and its separate cash flows for the years then ended in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (Korean IFRS).

Basis for Opinion

We conducted our audits in accordance with Korean Standards on Auditing. Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Financial Statements section of our report. We are independent of the Company in accordance with the ethical requirements of the Republic of Korea that are relevant to our audit of the separate financial statements and we have fulfilled our other ethical responsibilities in accordance with the ethical requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Other Matter

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

Responsibilities of Management and Those Charged with Governance for the separate Financial Statements

Management is responsible for the preparation and fair presentation of the separate financial statements in accordance with Korean IFRS, and for such internal control as management determines is necessary to enable the preparation of separate financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the separate financial statements, management is responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Company or to cease operations.

Those charged with governance are responsible for overseeing the Company’s financial reporting process.

Auditor’s Responsibilities for the Audit of the separate Financial Statements

Our objectives are to obtain reasonable assurance about whether the separate financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with Korean Standards on Auditing will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these separate financial statements.

 

1

As part of an audit in accordance with Korean Standards on Auditing, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

 

•

Identify and assess the risks of material misstatement of the separate financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

 

•

Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control.

 

•

Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.

 

•

Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the separate financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Company to cease to continue as a going concern.

 

•

Evaluate the overall presentation, structure and content of the separate financial statements, including the disclosures, and whether the separate financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December 31, 2025 and 2024

1. The Bank

Kookmin Bank (the “Bank”) was incorporated in 1963 under the Citizens National Bank Act to provide banking services to the general public and to small and medium-sized enterprises. Pursuant to the Repeal Act of the Citizens National Bank Act, effective January 5, 1995, the Bank’s status changed to a financial institution which operates under the Banking Act and Commercial Act.

The Bank merged with Korea Long Term Credit Bank on December 31, 1998, and with its subsidiaries, Daegu, Busan, Jeonnam Kookmin Mutual Savings & Finance Co., Ltd., on August 22, 1999. Pursuant to the directive from the Financial Services Commission related to the Structural Improvement of the Financial Industry Act in 1998, the Bank acquired certain assets, including performing loans, and assumed most of the liabilities of Daedong Bank on June 29, 1998. Also, the Bank completed the merger with Housing and Commercial Bank (“H&CB”) on October 31, 2001, and merged with Kookmin Credit Card Co., Ltd., a majority-owned subsidiary, on September 30, 2003. Meanwhile, the Bank spun off its credit card business segment on February 28, 2011, and KB Kookmin Card Co., Ltd. became a subsidiary of KB Financial Group Inc.

The Bank listed its shares on the Stock Market Division of the Korea Exchange (“KRX”) in September 1994. As a result of the merger with H&CB, the shareholders of the former Kookmin Bank and H&CB received new common shares of the Bank which were relisted on the KRX on November 9, 2001. In addition, H&CB listed its American Depositary Shares (“ADS”) on the New York Stock Exchange (“NYSE”) on October 3, 2000, prior to the merger. Following the merger with H&CB, the Bank listed its ADS on the NYSE on November 1, 2001. The Bank became a wholly owned subsidiary of KB Financial Group Inc. through a comprehensive stock transfer on September 29, 2008. Subsequently, the Bank’s shares and its ADS, each listed on the KRX and the NYSE, were delisted on October 10, 2008 and September 26, 2008, respectively. As of December 31, 2025, the Bank’s paid-in capital is W 2,021,896 million.

The Bank engages in the banking business in accordance with the Banking Act, trust business in accordance with the Financial Investment Services and Capital Markets Act, mobile virtual network business in accordance with Special Act on Support for Financial Innovation, and other relevant businesses. As of December 31, 2025, the Bank operates its Seoul headquarters and 771 domestic branches, and 11 overseas branches (excluding 5 subsidiaries).

2. Basis of Preparation

2.1 Application of Korean IFRS

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

The separate financial statements of the Bank 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 separate financial statements requires the use of certain critical accounting estimates. Management also needs to exercise judgment in applying the Bank’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 separate financial statements have been prepared in accordance with Korean IFRS No.1027 Separate Financial Statements.

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December 31, 2025 and 2024

2.1.1 The Bank has applied the following amended standards for the first time for its annual reporting period commencing January 1, 2025.

- Amendments 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 Bank 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 Bank is exposed. These amendments do not have a significant impact on the financial statements.

2.1.2 The following new and amended standards have been published that are not mandatory for December 31, 2025 reporting period and have not been adopted by the Bank.

- Amendments of Korean IFRS No.1109 “Financial Instruments” and No.1107 “Financial Instruments: Disclosures”

The amendments respond to recent questions arising in practice. The amendments will be applicable from the accounting year beginning on or after January 1, 2026, and early adoption is permitted. The main changes are as follows. The Bank is reviewing the impact of these amendments on the financial statements. These amendments do not have a significant impact on the financial statements.

 

•

allow the consideration of a financial liability as settled (derecognized) through an electronic payment system before the settlement date if certain criteria are met;

 

•

clarify and provide additional guidance for assessing whether a financial asset meets the solely payments of principal and interest (SPPI) criterion;

2.1.2 The following new and amended standards have been published that are not mandatory for December 31, 2025 reporting period and have not been adopted by the Bank. (cont’d)

- Korean IFRS No.1118 Presentation and Disclosures in Financial Statements

Korean IFRS No.1118 replaces Korean IFRS No.1001, carrying forward many of the requirements in Korean IFRS No.1001 unchanged and complementing them with new requirements. In addition, some paragraphs from Korean IFRS No.1001 have been moved to Korean IFRS No.1008 and Korean IFRS No.1107. Furthermore, minor amendments have been made to Korean IFRS No.1007 and Korean IFRS No.1033 Earnings per Share.

Korean IFRS No.1118 introduces new requirements to:

 

•

Present specified categories and defined subtotals in the statement of profit or loss

 

•

Provide disclosures on management-defined performance measures (MPMs) in the notes to the financial statements

 

•

Improve aggregation and disaggregation.

The Bank is required to apply Korean IFRS No.1118 for annual reporting periods beginning on or after January 1, 2027, with earlier application permitted. The amendments to Korean IFRS No.1007 and Korean IFRS No.1033, as well as the revised Korean IFRS No.1008 and Korean IFRS No.1107, become effective when The Bank applies Korean IFRS No.1118. Korean IFRS No.1118 requires retrospective application with specific transition provisions. The Bank is reviewing the impact of these amendments on the financial statements.

2.2 Measurement Basis

The separate 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 the Bank are measured using the currency of the primary economic environment in which the Bank operates (“functional currency”). The separate financial statements are presented in Korean won, which is the Bank’s functional and presentation currency.

2.4 Critical Accounting Estimates

The Bank applies accounting policies and uses judgments, accounting estimates, and assumptions that may have a significant impact on the assets (liabilities) and incomes (expenses) in preparing the separate financial statements. Management’s estimates of outcomes may differ from actual outcomes if management’s estimates and assumptions based on management’s best judgment 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 that may result in material adjustments to the separate financial statements are as follows:

2.4.1 Income taxes

As the income taxes on the Bank’s taxable income is calculated by applying the tax laws of various countries and the decisions of tax authorities, there is uncertainty in calculating the final tax effect.

2.4.2 Fair value of financial instruments

The fair value of financial instruments where no active market exists or where quoted prices are not otherwise available is determined by using valuation techniques. Financial instruments, which are not actively traded in the market and those with less transparent market prices, will have less objective fair values and require broad judgment on liquidity, concentration, uncertainty in market factors, assumptions in fair value determination, and other risks.

As described in the significant accounting policies in Note 3.3 Recognition and Measurement of Financial Instruments, diverse valuation techniques are used to determine the fair value of financial instruments, from generally accepted market valuation models to internally developed valuation models that incorporate various types of assumptions and variables.

2.4.3 Allowances and provisions for credit losses

The Bank recognizes and measures allowances for credit losses of debt instruments measured at amortized cost and debt instruments measured at fair value through other comprehensive income. Also, the Bank recognizes and measures provisions for credit losses of acceptances and guarantees, and unused loan commitments. Accuracy of allowances and provisions for credit losses is dependent upon estimation of expected cash flows of the borrower subject to individual assessment of impairment, and upon assumptions and variables of model used in collective assessment of impairment and estimation of provisions for credit losses of acceptances and guarantees, and unused loan commitments.

- Allowances and provisions for credit losses (Allowances, acceptances and guarantees, and unused commitments)

Economic uncertainty persists due to government regulations affecting the real estate market and the downturn in the construction sector driven by oversupply, while prolonged high interest rates increase repayment burdens and may lead to a deterioration in asset quality. Accordingly, the Bank has reflected the potential impact on expected credit losses though a management overlay, based on a comprehensive review of vulnerable sectors in the event that COVID-19 related support measures expire. In addition, the Bank estimates relevant risk parameters based on a holistic review and incorporates forward-looking economic information into those parameters. The Bank will continue to monitor the impact of economic uncertainty and government policies on expected credit losses. Further details of the impact on expected credit losses are presented in Note 11.1 Changes in allowances for credit losses of loans measured at amortized cost and Note 22.2 Changes in provisions for credit losses of unused loan commitments, and

acceptances and guarantees.

2.4.4 Net defined benefit asset (liability)

The present value of the net defined benefit asset(liability) is affected by changes in the various factors determined by the actuarial method.

2.4.5 Impairment of goodwill

The recoverable amounts of cash-generating units are determined based on value-in-use calculations to test whether impairment of goodwill has occurred.

3. Material Accounting Policies

The principal accounting policies applied in the preparation of these separate financial statements are set out below. These policies have been consistently applied to all the years presented, unless otherwise stated.

3.1 Investments in Associates and Subsidiaries

Associates are entities over which the Bank has significant influence over the financial and operating policy decisions. Generally, if the Bank holds 20% or more of the voting power of the investee, it is presumed that the Bank has significant influence.

Subsidiaries are companies that are controlled by the Bank. The Bank controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Also, the existence and effects of potential voting rights that are currently exercisable or convertible are considered when assessing whether the Bank controls the investee. Subsidiaries are fully consolidated from the date when control is transferred to the Bank and de-consolidated from the date when control is lost.

Investments in associates and subsidiaries are accounted for at cost in accordance with Korean IFRS No.1027. However, beneficiary certificates in private equity fund which is consolidated is classified as financial assets at fair value through profit or loss in accordance with Korean IFRS No.1109 and measured at fair value in accordance with Korean IFRS No.1113.

The Bank determines at each reporting period whether there is any objective evidence that the investments in the associates and subsidiaries that are accounted for by cost method are impaired. If this is the case, the Bank calculates the amount of impairment as the difference between the recoverable amount of the associate or subsidiary and its carrying amount and recognizes the amount as non-operating expenses in the statement of comprehensive income.

3.2 Foreign Currency

3.2.1 Foreign currency transactions

A foreign currency transaction is recorded, at initial recognition in the functional currency, by applying to the foreign currency amount the spot exchange rate between the functional currency and the foreign currency at the date of the transaction. At the end of each reporting period, foreign currency monetary items are translated using the closing rate which is the spot exchange rate at the end of the reporting period. Non-monetary items that are measured at fair value in a foreign currency are translated using the exchange rate at the date when the fair value was measured and non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rate at the date of the transaction.

Except for the exchange differences for the net investment in a foreign operation and the financial liability designated as a hedging instrument of net investment, exchange differences arising on the settlement of monetary items or on translating monetary items are recognized in profit or loss. When a gain or loss on a non-monetary item is recognized in other comprehensive income, any exchange component of that gain or loss is recognized in other comprehensive income. Conversely, when a gain or loss on a non-monetary item is recognized in profit or loss, any exchange component of that gain or loss is recognized in profit or loss.

3.2.2 Foreign operations

The results and financial position of a foreign operation, whose functional currency differs from the Bank’s presentation currency, are translated into the Bank’s presentation currency based on the following procedures.

If the functional currency of a foreign operation is not the currency of a hyperinflationary economy, assets and liabilities for each statement of financial position presented (including comparatives) are translated at the closing rate at the end of the reporting period, income and expenses for each statement of comprehensive income presented (including comparatives) are translated using the average exchange rates for the period. All resulting exchange differences are recognized in other comprehensive income.

Any goodwill arising on the acquisition of a foreign operation and any fair value adjustments to the carrying amounts of assets and liabilities arising on the acquisition of that foreign operation are treated as assets and liabilities of the foreign operation. Thus, they are expressed in the functional currency of the foreign operation and are translated into the presentation currency at the closing rate.

On the disposal of a foreign operation, the cumulative amount of the exchange differences relating to that foreign operation, recognized in other comprehensive income and accumulated in the separate component of equity, is reclassified from equity to profit or loss (as a reclassification adjustment) when the gain or loss on disposal is recognized. On the partial disposal of a subsidiary that includes a foreign operation, the Bank re-attributes the proportionate share of the cumulative amount of the exchange differences recognized in other comprehensive income to the non-controlling interests in that foreign operation. In any other partial disposal of a foreign operation, the Bank reclassifies to profit or loss only the proportionate share of the cumulative amount of the exchange differences recognized in other comprehensive income.

3.2.3 Translation of the net investment in a foreign operation

A monetary item that is receivable from or payable to a foreign operation, for which settlement is neither planned nor likely to occur in the foreseeable future is, in substance, a part of the Bank’s net investment in that foreign operation. The foreign currency difference arising from that monetary item is recognized in other comprehensive income and shall be reclassified to profit or loss on disposal of the net investment.

3.3 Recognition and Measurement of Financial Instruments

3.3.1 Initial recognition

The Bank recognizes a financial asset or a financial liability in its statement of financial position when the Bank becomes party to the contractual provisions of the instrument. A regular way purchase or sale of financial assets (a purchase or sale of a financial asset under a contract whose terms require delivery of the asset within the time frame established generally by regulation or convention in the marketplace concerned) is recognized and derecognized using trade date accounting.

For financial reporting purpose, the Bank classifies (a) financial assets as financial assets at fair value through profit or loss, financial assets at fair value through other comprehensive income, or financial assets at amortized cost and (b) financial liabilities as financial liabilities at fair value through profit or loss, or other financial liabilities. These classifications are based on the business model for managing financial instruments and the contractual cash flow characteristics of the financial instrument at initial recognition.

 

12

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December 31, 2025 and 2024

 

At initial recognition, a financial asset or financial liability is measured at its fair value plus or minus, in the case of a financial asset or financial liability not at fair value through profit or loss, transaction costs that are directly attributable to the acquisition or issue of the financial asset or financial liability. The 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 fair value of a financial instrument on initial recognition is normally the transaction price (that is, the fair value of the consideration given or received) in an arm’s length transaction.

3.3.2 Subsequent measurement

After initial recognition, financial instruments are measured at amortized cost or fair value based on classification at initial recognition.

3.3.2.1 Amortized cost

The amortized cost of a financial asset or financial liability is the amount at which the financial asset or financial liability is measured at initial recognition minus the principal repayments, plus or minus the cumulative amortization using the effective interest method of any difference between that initial amount and the maturity amount and, for financial assets, adjusted for any loss allowance.

3.3.2.2 Fair value

The Bank uses quoted price in an active market which is based on listed market price or dealer price quotations of financial instruments traded in an active market as best estimate of fair value. A financial instrument is regarded as quoted in an active market if quoted prices are readily and regularly available from an exchange, dealer, broker, industry group, pricing service or regulatory agency, and those prices represent actual and regularly occurring market transactions on an arm’s length basis.

If there is no active market for a financial instrument, fair value is determined either by using a valuation technique or independent third-party valuation service. Valuation techniques include using recent arm’s length market transactions between knowledgeable and willing parties, if available, referencing the current fair value of another instrument that is substantially the same, discounted cash flow analysis, and option pricing models.

The Bank uses valuation models that are commonly used by market participants and customized for the Bank to determine fair values of common over-the-counter (“OTC”) derivatives such as options, interest rate swaps, and currency swaps which are based on the inputs observable in markets. However, for some complex financial instruments that require fair value measurement by valuation techniques based on certain assumptions because some or all inputs used in the model are not observable in the market, the Bank uses internal valuation models developed from general valuation models or valuation results from independent external valuation institutions.

In addition, the fair value information recognized in the statement of financial position is classified into the following fair value hierarchy, reflecting the significance of the input variables used in the fair value measurement.

 

Level 1 :		Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Bank can access at the measurement date
Level 2 :		Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly
Level 3 :		Unobservable inputs for the asset or liability

 

13

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December 31, 2025 and 2024

 

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. For this purpose, the significance of an input is assessed against the fair value measurement in its entirety.

If a fair value measurement uses observable inputs that require significant adjustment using unobservable inputs, that measurement is a Level 3 measurement.

The Bank’s Fair Value Evaluation Committee, which consists of the risk management department, trading department and accounting department, reviews the appropriateness of internally developed valuation models, and approves the selection and changing of the external valuation institution and other considerations related to fair value measurement. The results of regular verification of the internally developed valuation models are reported to the Market Risk Management Subcommittee.

If the valuation technique does not reflect all factors which market participants would consider in pricing the asset or liability, the fair value is adjusted to reflect those factors. Those factors include counterparty credit risk, liquidity risk, and others.

The Bank uses a valuation technique which maximizes the use of market inputs and minimizes the use of entity-specific inputs. It incorporates all factors that market participants would consider in pricing the asset or liability and is consistent with economic methodologies applied for pricing financial instruments. Periodically, the Bank calibrates the valuation technique and tests its validity using prices of observable current market transactions of the same instrument or based on other relevant observable market data.

3.3.3 Derecognition

Derecognition is the removal of a previously recognized financial asset or financial liability from the statement of financial position. The derecognition criteria for financial assets and financial liabilities are as follows:

3.3.3.1 Derecognition of financial assets

A financial asset is derecognized when the contractual rights to the cash flows from the financial assets expire or the Bank transfers substantially all the risks and rewards of ownership of the financial asset, or the Bank neither transfers nor retains substantially all the risks and rewards of ownership of the financial asset and the Bank has not retained control. Therefore, if the Bank does not transfer substantially all the risks and rewards of ownership of the financial asset, the Bank continues to recognize the financial asset to the extent of its continuing involvement in the financial asset.

If the Bank transfers the contractual rights to receive the cash flows of the financial asset but retains substantially all the risks and rewards of ownership of the financial asset, the Bank continues to recognize the transferred asset in its entirety and recognize a financial liability for the consideration received.

The Bank writes off a financial asset when the Bank has no reasonable expectations of recovering a financial asset in its entirety or a portion thereof. In general, the Bank considers write-off when it is determined that the debtor does not have sufficient funds or income to cover the principal and interest. The write-off decision is made in accordance with internal policy. After the write-off, the Bank can continue to collect the written-off loans according to the internal policy. Recovered amounts from financial assets previously written-off are recognized in profit or loss.

3.3.3.2 Derecognition of financial liabilities

A financial liability is derecognized from the statement of financial position when it is extinguished (i.e., the obligation specified in the contract is discharged, canceled or expires).

3.3.4 Offsetting

A financial asset and a financial liability are offset, and the net amount is presented in the statement of financial position when, and only when, the Bank currently has a legally enforceable right to offset the recognized amounts and intends either to settle on a net basis, or to realize the asset and settle the liability simultaneously. The legally enforceable right must not be contingent on a future event and must be legally enforceable in the normal course of business, the event of default, and the event of insolvency or bankruptcy of the Bank and all of the counterparties.

3.4 Cash and Due from Financial Institutions

Cash and due from financial institutions include cash on hand, foreign currency, and short-term, highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value, and due from financial institutions. Cash and due from financial institutions are measured at amortized cost.

3.5 Non-derivative Financial Assets

3.5.1 Financial assets at fair value through profit or loss

Financial assets are classified as financial assets at fair value through profit or loss unless they are classified as financial assets at amortized cost or at fair value through other comprehensive income.

The Bank may designate certain financial assets upon initial recognition as at fair value through profit or loss when the designation eliminates or significantly reduces a measurement or recognition inconsistency (sometimes 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.

After initial recognition, a financial asset at fair value through profit or loss is measured at fair value and gains or losses arising from a change in fair value are recognized in profit or loss. Interest income using the effective interest method and dividend income from financial assets at fair value through profit or loss are also recognized in profit or loss.

3.5.2 Financial assets at fair value through other comprehensive income

The Bank classifies below financial assets as financial assets at fair value through other comprehensive income:

Debt instruments that are held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets, and where the assets’ cash flows solely represent payments of principal and interest on the principal amount outstanding and; Equity instruments that are not held for short-term trading but held for strategic investment, and designated as financial assets at fair value through other comprehensive income

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December 31, 2025 and 2024

 

After initial recognition, a financial asset at fair value through other comprehensive income is measured at fair value. Gains or losses arising from a change in fair value, other than dividend income, interest income calculated using the effective interest method and exchange differences arising on monetary items which are recognized directly in profit or loss, are recognized in other comprehensive income in equity.

When the financial assets at fair value through other comprehensive income is disposed of, the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to profit or loss. However, cumulative gain or loss of equity instruments designated at fair value through other comprehensive income is reclassified to retained earnings not to profit or loss at disposal.

A financial asset at fair value through other comprehensive income denominated in foreign currency is translated at the closing rate. Exchange differences resulting from changes in amortized cost are recognized in profit or loss, and other changes are recognized in equity.

3.5.3 Financial assets at amortized cost

A financial asset, which is held within the business model whose objective is achieved by collecting contractual cash flows, and where the assets’ cash flows represent solely payments of principal and interest on the principal amount outstanding, is classified as a financial asset at amortized cost. After initial recognition, a financial asset at amortized cost is measured at amortized cost using the effective interest method and interest income is calculated using the effective interest method.

3.6 Expected Credit Losses of Financial Assets (Debt Instruments)

The Bank recognizes loss allowances for expected credit losses at the end of the reporting period for financial assets at amortized cost and fair value through other comprehensive income except for financial assets at fair value through profit or loss.

Expected credit losses are estimated at present value of probability-weighted amount that is determined by evaluating a range of possible outcomes. The Bank measures expected credit losses by reflecting all reasonable and supportable information that is available without undue cost or effort at the reporting date about past events, current conditions, and forecasts of future economic conditions.

The approaches of measuring expected credit losses in accordance with Korean IFRS are as follows:

 

•

General approach: for financial assets and unused loan commitments not subject to the below approach

 

•

Credit-impaired approach: for financial assets that are credit-impaired at the time of acquisition

Application of general approach is differentiated depending on whether credit risk has increased significantly after initial recognition. If the credit risk on a financial instrument has not increased significantly since initial recognition, the Bank measures loss allowances for that financial instrument at an amount equal to 12-month expected credit losses, whereas if the credit risk on a financial instrument has increased significantly since initial recognition, the Bank measures loss allowances for a financial instrument at an amount equal to the lifetime expected credit losses. Lifetime is the period until the contractual maturity date of financial instruments and means the expected life.

The Bank assesses whether the credit risk has increased significantly using the following criteria, and if one or more of the following criteria are met, it is deemed as significant increase in credit risk. If the contractual cash flows of a financial asset have been renegotiated or modified, the Bank assesses whether the credit risk has increased significantly using the same following criteria.

3.6.1 Forward-looking information

The Bank uses forward-looking information, when determining whether credit risk has increased significantly and measuring expected credit losses.

The Bank assumes that the risk components have a constant correlation with the economic cycle and uses statistical methodologies to estimate the relation between key macroeconomic variables and risk components for the expected credit losses. The Bank has derived a correlation between the time series data of 15 years or more and the key macroeconomic variables and calculates the expected credit losses by reflecting the results of the correlation on the risk component.

The correlation between the major macroeconomic variables and the credit risk are as follows:

 

Key macroeconomic variables		Correlation between the major macroeconomic variables and the credit risk
Benchmark interest rate		(+)
AA- rated corporate bond (3-year)		(+)
BBB- rated corporate bond (3-year)		(+)
Composite stock index		(-)
Rate of increase in housing transaction price index (Whole Country)		(-)
Rate of increase in housing transaction price index (Metropolitan Area)		(-)
WTI crude oil price		(+)

Forward-looking information used in the calculation of expected credit losses is based on the macroeconomic forecasts utilized by management of the Bank for its business plan considering reliable external agency’s forecasts and others. The forward-looking information is generated by KB Research with a comprehensive approach to capture the possibility of various economic forecast scenarios that are derived from the internal and external viewpoints of the macroeconomic situation. The Bank determines the macroeconomic variables to be used in forecasting future conditions of the economy, considering the direction of the forecast scenario based on GDP growth and the significant relationship between macroeconomic variables and time series data. Some macroeconomic variables used are different than those used in the previous year.

Notes to the Separate Financial Statements

December 31, 2025 and 2024

 

As of December 31, 2025, the Bank measures expected credit losses by applying both the worse scenario and the crisis scenario, taking into consideration the potential credit risk resulting from the uncertain financial environment locally and globally and the rapid economic recession.

If we assume a probability weight of 100% for each scenario, the impact on expected credit loss allowances and provisions would be as follows.

 

(In millions of Korean won)
Scenario		Applied probability weight		Assumption of 100%				Difference from the book value
Deterioration		80%			1,656,592				(873,402)
Crisis situation		20%			6,036,819				3,506,825

3.6.2 Measuring expected credit losses on financial assets at amortized cost

The expected credit losses of financial assets at amortized cost are measured as present value of the difference between the contractual cash flows to be received and the cash flows expected to be received. The Bank estimates expected future cash flows for financial assets that are individually significant. The Bank selects the individually significant financial assets by comprehensively considering quantitative and qualitative factors (such as debt restructuring or negative net assets, etc.) when the credit risk has increased significantly or the financial asset in credit-impaired (individual assessment of impairment).

For financial assets that are not individually significant, the Bank collectively estimates expected credit losses by grouping loans with a homogeneous credit risk profile (collective assessment of impairment).

3.6.2.1 Individual assessment of impairment

Individual assessment of impairment losses is performed using management’s best estimate on the present value of expected future cash flows. The Bank uses all the available information including financial condition of the borrower such as operating cash flow and net realizable value of any collateral held.

3.6.2.2 Collective assessment of impairment

Collective assessment of impairment losses is performed by using a methodology based on historical loss experience and reflecting forward-looking information. Such a process incorporates factors such as type of collateral, type of product, type of borrower, credit rating, size of portfolio, and recovery period and applies Probability of Default (“PD”) on a group of assets and Loss Given Default (“LGD”) by type of recovery method. Also, the Bank applies certain assumptions to model expected credit losses assessment and to determine input based on loss experience and forward-looking information. These models and assumptions are periodically reviewed to reduce the gap between loss estimate and actual loss experience.

The lifetime expected credit losses are measured by applying the PD to the carrying amount, which is calculated by deducting the expected principal repayment amount from the carrying amount as of the reporting date, and the LGD adjusted to reflect changes in the carrying amount.

3.6.3 Measuring expected credit losses on financial assets at fair value through other comprehensive income

The Bank measures expected credit losses on financial assets at fair value through other comprehensive income in a manner that is consistent with the requirements that are applicable to financial assets at amortized cost. However, loss allowances are recognized in other comprehensive income. Upon disposal or repayment of financial assets at fair value through other comprehensive income, the amount of loss allowances is reclassified from other comprehensive income to profit or loss.

3.7 Derivative Financial Instruments

The Bank enters into numerous derivative financial instrument contracts such as currency forwards, interest rate swaps, currency swaps, and others for trading purposes or to manage its interest rate risk, currency risk, and others. The Bank’s derivative financial instruments business focuses on addressing the needs of the Bank’s corporate clients to hedge their risk exposure and to hedge the Bank’s risk exposure that results from such client contracts. These derivative financial instruments are presented as derivative financial instruments in the financial statements irrespective of transaction purpose and subsequent measurement requirement.

The Bank designates certain derivative financial instruments as hedging instruments to hedge the risk of changes in fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge) and the risk of changes in cash flow (cash flow hedge).

At the inception of the hedging relationship, there is formal designation and documentation of the hedging relationship and the Bank’s risk management objective and strategy for undertaking the hedge. This documentation includes identification of the hedging instrument, the hedged item, the nature of the risk being hedged, the inception date of hedging relationship and how the Bank will assess the hedging instrument’s effectiveness in offsetting the changes in the hedged item’s fair value or cash flows attributable to the hedged risk.

Derivative financial instruments are initially recognized at fair value. After initial recognition, derivative financial instruments are measured at fair value, and changes therein are accounted for as described below.

3.7.1 Derivative financial instruments held for trading

All derivative financial instruments, except for derivatives that are designated and qualify for hedge accounting, are measured at fair value. Gains or losses arising from changes in fair value are recognized in profit or loss as part of net gains or losses on financial instruments at fair value through profit or loss.

3.7.2 Derivative financial instruments for fair value hedges

If derivative financial instruments are designated and qualify for fair value hedges, changes in fair value of the hedging instrument and changes in fair value of the hedged item attributable to the hedged risk are recognized in profit or loss as part of other operating income or expenses. If the hedged items are equity instruments for which the Bank has elected to present changes in fair value in other comprehensive income, changes in fair value of the hedging instrument and changes in fair value of the hedged item attributable to the hedged risk are recognized in other comprehensive income.

Fair value hedge accounting is discontinued prospectively if the hedging instrument expires or is sold, terminated or exercised, or the hedging relationship ceases to meet the qualifying criteria. Once fair value hedge accounting is discontinued, the adjustment to the carrying amount of a hedged item is amortized to profit or loss by the maturity of the financial instrument using the effective interest method.

3.7.3 Derivative financial instruments for cash flow hedges

The effective portion of changes in fair value of derivative financial instruments that are designated and qualify for cash flow hedges is recognized in other comprehensive income, limited to the cumulative change in fair value (present value) of the hedged item (the present value of the cumulative change in the hedged expected future cash flows) from inception of the hedge. The ineffective portion is recognized in profit or loss as other operating income or expenses. The associated gains or losses that were previously recognized in other comprehensive income are reclassified from equity to profit or loss (other operating income or expenses) as a reclassification adjustment in the same period or periods during which the hedged forecast cash flows affect profit or loss. Cash flow hedge accounting is discontinued prospectively if the Bank’s risk management strategy or objective changes, or if the hedging instrument expires, is sold, terminated or exercised, or the hedging relationship ceases to meet the qualifying criteria. When the cash flow hedge accounting is discontinued, the cumulative gains or losses on the hedging instrument that have been recognized in other comprehensive income are reclassified to profit or loss over the period in which the forecast transaction occurs. If the forecast transaction is no longer expected to occur, the cumulative gains or losses that have been recognized in other comprehensive income are immediately reclassified to profit or loss.

3.7.4 Risk management strategy

Interest rate risk arises from changes in fair value resulting from changes in the discount rate of fixed rate financial instruments and changes in cash flows resulting from changes in the nominal interest rate of floating rate financial instruments.

The Bank hedges the interest rate risk in its entirety. At inception of the hedge relationship, the Bank reviews the hedge effectiveness; and periodically reviews the effectiveness in order to confirm that economic relationship between the hedged item and the hedging instrument exists. The requirement that an economic relationship exists means that the hedging instrument and the hedged item have values that generally move in the opposite direction due to the same risk, which is the hedged risk. The Bank designates the exposure of hedged item opposite to the exposure of hedging instruments in order to meet economic relationship requirement.

The Bank designates the hedge relationship at a one-on-one ratio between the nominal amount of the hedging instrument and the nominal amount of the hedged item.

Hedge ineffectiveness could arise because of differences in the underlying parameters (acquisition date, credit risk or liquidity and others) or other differences between the hedging instrument and the hedged item that the Bank accepts in order to achieve a cost-effective hedging relationship.

The Bank avoids the cash flow variability of its floating rate debt securities by using interest rate swaps. Both are linked to the same interest rate; however, the paid amount of the floating rate may be set on different dates. Even if the variability of interest rate related cash flows (as a risk factor) is designated as a hedged item, the difference in set-up dates creates a hedge ineffectiveness.

The Bank avoids the variability of fair values of its fixed rate debt securities by using interest rate swaps. The method of calculating the number of dates for paying fixed-rate interest can be different between hedging instruments and hedged items. Even if the variability of the fair value due to the benchmark interest rate (as a risk factor) is designated as a hedged item, the difference in the method of calculating the number of the dates creates a hedge ineffectiveness.

3.7.5 Embedded derivatives

An embedded derivative is separated from the host contract and accounted for as a derivative if, and only if, (a) the economic characteristics and risks of the embedded derivative are not closely related to those of the host contract, (b) a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative and (c) the hybrid contract contains a host that is not a financial asset and is not designated as at fair value through profit or loss. Gains or losses arising from a change in fair value of an embedded derivative separated from the host contract are recognized in profit or loss as part of net gains or losses on financial instruments at fair value through profit or loss.

3.7.6 Day one gains or losses

If the Bank uses a valuation technique that incorporates unobservable inputs for the fair value of the OTC derivatives at initial recognition, there may be a difference between the transaction price and the amount determined using that valuation technique. In these circumstances, 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. If the fair value is subsequently determined using observable inputs, the remaining deferred amount is recognized in profit or loss as part of net gains or losses on financial instruments at fair value through profit or loss or other operating income or expenses.

3.8 Property and Equipment

3.8.1 Recognition and measurement

Property and equipment that qualify for recognition as an asset are measured at cost and subsequently carried at its cost less any accumulated depreciation and any accumulated impairment losses.

The cost of property and equipment includes any costs directly attributable to bringing the asset to the location and the asset’s condition necessary for it to be capable of operating in the manner intended by management and the initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located.

Subsequent expenditures are capitalized only when they prolong the useful life or enhance values of the assets, but the costs of the day-to-day servicing of the assets such as repair and maintenance costs are recognized in profit or loss as incurred. When part of an item of property and equipment has a useful life different from that of the entire asset, it is recognized as a separate asset.

3.8.2 Depreciation

Land is not depreciated, whereas other property and equipment are depreciated using the method that reflects the pattern in which the asset’s future economic benefits are expected to be consumed by the Bank. The depreciable amount of an asset is determined after deducting its residual value.

Each part of an item of property and equipment with a cost that is significant in relation to the total cost of the item is depreciated separately.

The depreciation method and estimated useful life of property and equipment are as follows:

 

Property and equipment		Depreciation method		Estimated useful life
Buildings		Straight-line		40 years
Leasehold improvements		Diminishing-balance		4 years
Equipment and vehicles		Diminishing-balance		4 years

Kookmin Bank (A wholly owned subsidiary of KB Financial Group Inc.)

Notes to the Separate Financial Statements

December 31, 2025 and 2024

 

The residual value, the useful life, and the depreciation method applied to an asset are reviewed at each financial year-end and, if expectations differ from previous estimates, the changes are accounted for as a change in an accounting estimate.

3.9 Investment Properties

3.9.1 Recognition and measurement

Properties held to earn rentals or for capital appreciation or both are classified as investment properties. Investment properties are measured initially at their cost and subsequently the cost model is used.

3.9.2 Depreciation

Land is not depreciated, whereas other investment properties are depreciated using the method that reflects the pattern in which the asset’s future economic benefits are expected to be consumed by the Bank. The depreciable amount of an asset is determined after deducting its residual value.

The depreciation method and estimated useful life of investment properties are as follows:

 

Investment properties		Depreciation method		Estimated useful life
Buildings		Straight-line		40 years

The residual value, the useful life, and the depreciation method applied to an asset are reviewed at each financial year-end and, if expectations differ from previous estimates, the changes are accounted for as a change in an accounting estimate.

3.10 Intangible Assets

Intangible assets are measured initially at cost and subsequently carried at their cost less any accumulated amortization and any accumulated impairment losses.

Intangible assets, except for goodwill and membership rights, are amortized using the straight-line method with no residual value over their estimated useful life since the assets are available for use.

 

Intangible assets		Amortization method		Estimated useful life
Industrial property rights		Straight-line		5 years
Software		Straight-line		4~5 years
Others		Straight-line		1~13 years

The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at each financial year-end. Where an intangible asset is not being amortized because its useful life is indefinite, the Bank carries out a review in each accounting period to confirm whether events and circumstances still support an indefinite useful life assessment. If they do not, the change in the useful life assessment from indefinite to finite is accounted for as a change in an accounting estimate.

3.10.1 Goodwill

3.10.1.1 Recognition and measurement

Goodwill related to business combinations before January 1, 2010, is stated at its carrying amount, which was recognized under the Bank’s previous accounting policy, prior to the transition to Korean IFRS.

Goodwill acquired from business combinations after January 1, 2010, is initially measured as the excess of the consideration transferred over the fair value of net identifiable assets acquired and liabilities assumed. If the fair value of net identifiable assets acquired and liabilities assumed exceeds the consideration transferred, the difference is recognized in profit or loss.

Acquisition-related costs incurred to effect a business combination are charged to expenses in the periods in which the costs are incurred and the services are received, except for the costs to issue debt or equity securities.

3.10.1.2 Subsequent measurement

Goodwill is not amortized and is stated at cost less accumulated impairment losses. Goodwill that forms part of the carrying amount of an investment in associates and subsidiaries is not separately recognized, and an impairment loss recognized is not allocated to any asset, including goodwill, which forms part of the carrying amount of the investment in the associates.

3.10.2 Subsequent expenditures

Subsequent expenditures are capitalized only when they enhance values of the assets. Internally generated intangible assets, such as goodwill and trade name, are not recognized as assets but expensed as incurred.

3.11 Impairment of Non-financial Assets

The Bank assesses at the end of each reporting period whether there is any indication that a non-financial asset, except for (a) deferred income tax assets, (b) assets arising from employee benefits and (c) non-current assets (or group of assets to be sold) classified as held for sale, may be impaired. If any such indication exists, the Bank estimates the recoverable amount of the asset. However, irrespective of whether there is any indication of impairment, the Bank tests (a) goodwill acquired in a business combination, (b) intangible assets with an indefinite useful life and (c) intangible assets not yet available for use for impairment annually by comparing their carrying amount with their recoverable amount.

The recoverable amount is estimated for the individual asset. If it is not possible to estimate the recoverable amount of the individual asset, the Bank determines the recoverable amount of the cash-generating unit to which the asset belongs. A cash-generating unit is the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. The recoverable amount of an asset is the higher of its fair value less costs of disposal and its value in use. Value in use is the present value of the future cash flows expected to be derived from an asset or cash-generating unit that are discounted by a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the future cash flow estimates have not been adjusted.

If the recoverable amount of an asset is less than its carrying amount, the carrying amount of the asset is reduced to its recoverable amount. That reduction is an impairment loss and recognized immediately in profit or loss. For the purpose of impairment testing, goodwill acquired in a business combination is allocated to each of the cash-generating units that is expected to benefit from the synergies of the combination. The impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the cash-generating unit and then to the other assets of the unit pro rata on the basis of the carrying amount of each asset in the unit.

An impairment loss recognized for goodwill is not reversed in a subsequent period. The Bank assesses at the end of each reporting period whether there is any indication that an impairment loss recognized in prior periods for an asset, other than goodwill, may no longer exist or may have decreased, and an impairment loss recognized in prior periods for an asset other than goodwill shall be reversed if, and only if, there has been a change in the estimates used to determine the asset’s recoverable amount since the last impairment loss was recognized. The increased carrying amount of an asset other than goodwill attributable to a reversal of an impairment loss cannot exceed the carrying amount that would have been determined (net of amortization or depreciation) had no impairment loss been recognized for the asset in prior years.

3.12 Non-current Assets Held for Sale

A non-current asset or disposal group is classified as held for sale if its carrying amount will be recovered principally through a sale transaction rather than through continuing use. For this to be the case, the asset (or disposal group) must be available for immediate sale in its present condition and its sale must be highly probable. A non-current asset (or disposal group) classified as held for sale is measured at the lower of (a) its carrying amount measured in accordance with the applicable Korean IFRS, immediately before the initial classification of the asset (or disposal group) as held for sale and (b) fair value less costs to sell.

A non-current asset is not depreciated (or amortized) while it is classified as held for sale or is part of a disposal group classified as held for sale.

Impairment loss is recognized for any initial or subsequent write-down of the asset (or disposal group) to fair value less costs to sell. Gain is recognized for any subsequent increase in fair value less costs to sell of an asset, but not in excess of the cumulative impairment loss that has been recognized.

3.13 Financial Liabilities

The Bank classifies financial liabilities into financial liabilities at fair value through profit or loss or other financial liabilities in accordance with the substance of the contractual arrangement and the definitions of financial liabilities. The Bank recognizes financial liabilities in the statement of financial position when the Bank becomes a party to the contractual provisions of the financial liability.

3.13.1 Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading or designated as such at initial recognition. After initial recognition, financial liabilities at fair value through profit or loss are measured at fair value, and changes therein are recognized in profit or loss. At initial recognition, transaction costs that are directly attributable to the acquisition are recognized in profit or loss as incurred.

In relation to securities lending or borrowing transactions, when the Bank borrows securities from the Korea Securities Depository and others, these transactions are managed as off-balance sheet items. The borrowed securities are treated as financial liabilities at fair value through profit or loss when they are sold. Changes in fair value at the end of the reporting period and difference between carrying amount at redemption and purchased amount are recognized in profit or loss.

3.13.2 Other financial liabilities

Non-derivative financial liabilities other than financial liabilities at fair value through profit or loss are classified as other financial liabilities. Other financial liabilities include deposits, borrowings, debentures, and others. At initial recognition, other financial liabilities are measured at fair value minus transaction costs that are directly attributable to the acquisition. After initial recognition, other financial liabilities are measured at amortized cost, and its interest expense is recognized, using the effective interest method.

When an asset is sold under repurchase agreement, the Bank continues to recognize the asset with the amount sold being accounted for as borrowings. The Bank derecognizes a financial liability from the statement of financial position only when it is extinguished (i.e., when the obligation specified in the contract is discharged, canceled or expires).

3.14 Provisions

Provisions are recognized when the Bank has a present obligation (legal or constructive) as a result of a past event and it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Inevitable risks and uncertainties surrounding related events and circumstances are considered in measuring the best estimate of the provisions, and where the effect of the time value of money is material, the amount of provisions is the present value of the expenditures expected to be required to settle the obligation.

Provisions for confirmed and unconfirmed acceptances and guarantees, and unused credit lines of consumer and corporate loans are recognized using a valuation model that applies the credit conversion factor, PD, and LGD.

Provisions are reviewed at the end of each reporting period and adjusted to reflect the current best estimate. If it is no longer probable that an outflow of resources embodying economic benefits will be required to settle the obligation, the provisions are reversed.

An onerous contract is a contract in which the unavoidable costs of meeting the obligations under the contract exceed the economic benefits expected to be received under it. The unavoidable costs under a contract reflect the least net cost of exiting from the contract, which is the lower of the cost of fulfilling it and any compensation or penalties arising from failure to fulfill it. If the Bank has a contract that is onerous, the present obligation under the contract is recognized and measured as provisions.

3.15 Financial Guarantee Contracts

Financial guarantee contracts 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 original or modified terms of a debt instrument.

Financial guarantee contracts are initially recognized at fair value, and classified as other liabilities and are amortized over the contractual term. After initial recognition, financial guarantee contracts are measured at the higher of:

 

•

The amount determined in accordance with Korean IFRS No.1109 Financial Instruments and

 

•

The amount initially recognized less, when appropriate, the cumulative amount of income recognized in accordance with Korean IFRS No.1115 Revenue from Contracts with Customers.

3.16 Equity Instrument Issued by the Bank

An equity instrument is any contract or agreement that evidences a residual interest in the assets of an entity after deducting all of its liabilities.

3.16.1 Ordinary shares

Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new shares or the exercise of stock option are deducted from the equity, net of any tax effects.

3.16.2 Hybrid securities

The financial instruments can be classified as either financial liabilities or equity in accordance with the terms of the contract. The Bank classifies hybrid securities as an equity if the Bank has the unconditional right to avoid any contractual obligation to deliver cash or another financial asset in relation to the financial instruments.

3.16.3 Compound financial instruments

A compound financial instrument is classified as a financial liability or an equity instrument depending on the substance of the contractual arrangement of such financial instrument. The liability component of the compound financial instrument is measured at fair value of the similar liability without conversion option at initial recognition and subsequently measured at amortized cost using effective interest method until it is extinguished by conversion or matured. The equity component is initially measured at fair value of compound financial instrument in its entirety less fair value of liability component net of tax effect, and it is not remeasured subsequently.

3.17 Revenue Recognition

The Bank recognizes revenues in accordance with the following steps determined in accordance with Korean IFRS No.1115 Revenue from Contracts with Customers.

 

•

Step 1: Identify the contract with a customer.

 

•

Step 2: Identify the performance obligations in the contract.

 

•

Step 3: Determine the transaction price.

 

•

Step 4: Allocate the transaction price to the performance obligations in the contract.

 

•

Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.

3.17.1 Interest income and expense

Interest income and expense on debt securities at fair value through profit or loss (excluding beneficiary certificates, equity investments, and other debt instruments), loans, financial instruments at amortized cost, and debt securities at fair value through other comprehensive income are recognized in the statement of comprehensive income using the effective interest method in accordance with Korean IFRS No.1109 Financial Instruments. The effective interest method is a method of calculating the amortized cost of a financial asset or a financial liability and allocating the interest income or interest expense over the relevant period.

The effective interest rate is the rate that exactly discounts estimated future cash receipts or payments through the expected life of the financial instrument or, where 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 Bank estimates expected cash flows by considering all contractual terms of the financial instrument but does not consider expected credit losses. The calculation includes all fees and points paid (main components of effective interest rate only) or received between parties to the contract that are an integral part of the effective interest rate, transaction costs, and all other premiums or discounts. In those rare cases when it is not possible to reliably estimate the cash flows and the expected life of a financial instrument, the Bank uses the contractual cash flows over the full contractual term of the financial instrument.

Interest income on impaired financial assets is recognized using the interest rate used to discount the expected cash flows for the purpose of measuring the impairment loss. Interest income on debt securities at fair value through profit or loss is also classified as interest income in the statement of comprehensive income.

3.17.2 Fee and commission income

The Bank recognizes financial service fees in accordance with the purpose of charging the fees and the accounting standards of the financial instrument related to the fees earned.

3.17.2.1 Fees that are an integral part of the effective interest of a financial instrument

Such fees are generally treated as adjustments of effective interest rate. Such fees may include compensation for activities such as evaluating the borrower’s financial condition, evaluating and recording guarantees, collateral and other security arrangements, negotiating the terms of the instrument, preparing and processing documents, and closing the transaction and origination fees received on issuing financial liabilities at amortized cost. However, fees relating to the creation or acquisition of a financial instrument at fair value through profit or loss are recognized as revenue immediately.

3.17.2.2 Fees related to performance obligations satisfied over time

If the control of a good or service is transferred over time, the Bank recognizes revenue related to performance obligations over the period of performance obligations. Fees charged in return for the services for a certain period of time, such as asset management fees, consignment business fees, etc. are recognized over the period of performance obligations.

3.17.2.3 Fees related to performance obligations satisfied at a point in time

Fees earned at a point in time are recognized as revenue when a customer obtains control of a promised good or service and the Bank satisfies a performance obligation.

Commission on negotiation or participation in negotiation for the third party such as trading stocks or other securities, arranging merger and acquisition of business, is recognized as revenue when the transaction has been completed.

If the Bank arranges a syndicated loan but does not participate in the syndicated loan or participates in the syndicated loan with the same effective profit as other participants, a syndication arrangement fee is recognized as revenue at the completion of the syndication service.

3.17.3 Net gains or losses on financial instruments at fair value through profit or loss

Net gains or losses on financial instruments at fair value through profit or loss (including changes in fair value, dividends, and gains or losses from foreign currency translation) include gains or losses on financial instruments as follows:

 

•

Gains or losses relating to financial instruments at fair value through profit or loss (excluding interest income using the effective interest rate method)

 

•

Gains or losses relating to derivative financial instruments for trading (including derivative financial instruments for hedging purpose but do not qualify for hedge accounting)

3.17.4 Dividend income

Dividend income is recognized in profit or loss when the right to receive payment is established. Dividend income is recognized as net gains or losses on financial instruments at fair value through profit or loss or other operating income depending on the classification of equity securities.

3.18 Employee Compensation and Benefits

3.18.1 Post-employment benefits

3.18.1.1 Defined contribution plans

When an employee has rendered service to the Bank during a period, the Bank recognizes the contribution payable to a defined contribution plan in exchange for that service as post-employment benefits for the period.

3.18.1.2 Defined benefit plans

All post-employment benefits, other than defined contribution plans, are classified as defined benefit plans. The amount recognized as a net defined benefit liability is the present value of the defined benefit obligation less the fair value of plan assets at the end of the reporting period.

The present value of the defined benefit obligation is calculated annually by a qualified actuary using the projected unit credit method. The rate used to discount post-employment benefit obligations is determined by reference to market yields at the end of the reporting period on high quality corporate bonds. The currency and term of the corporate bonds are consistent with the currency and estimated term of the post-employment benefit obligations. Actuarial gains and losses resulting from changes in actuarial assumptions and experience adjustments are recognized in other comprehensive income.

When the present value of the defined benefit obligation minus the fair value of plan assets results in an asset, it is recognized to the extent of the present value of any economic benefits available in the form of refunds from the plan or reductions in future contributions to the plan.

Past service cost is the change in the present value of the defined benefit obligation for employee service in prior periods, resulting from the introduction or changes to a defined benefit plan. Such past service cost is immediately recognized as an expense for the period.

3.18.2 Short-term employee benefits

Short-term employee benefits are employee benefits that are expected to be settled wholly before twelve months after the end of the annual reporting period in which the employees render the related service. When an employee has rendered service to the Bank during an accounting period, the Bank recognizes the undiscounted amount of short-term employee benefits expected to be paid in exchange for that service as an expense for the period.

The expected cost of profit-sharing and bonus payments is recognized as liabilities when the Bank has a present legal or constructive obligation to make payments as a result of past events, such as service rendered by employees, and a reliable estimate of the obligation can be made.

3.18.3 Share-based payment

The Bank provides its executives and employees with stock grants and mileage stock programs. When stock grants are exercised, the Bank can either select to distribute shares of KB Financial Group Inc., the Parent Company or compensate in cash based on the share price. When mileage stock is exercised, the Bank pays the amount equivalent to share price of KB Financial Group Inc. in cash.

For a share-based payment transaction in which the terms of the arrangement provide the Bank with the choice of whether to settle in cash or by issuing equity instruments, the Bank accounts for the transaction in accordance with the requirements applying to cash-settled share-based payment transactions because the Bank determines that it has a present obligation to settle in cash based on a past practice and a stated policy of settling in cash. Therefore, the Bank measures the liability incurred as consideration for the service received at fair value and recognizes related expense and accrued expense over the vesting periods. For mileage stock, the Bank accounts for the transaction in accordance with the requirements applying to cash-settled share-based payment transactions, which are recognized as expenses and accrued expenses at the time of vesting.

Until the liability is settled, the Bank remeasures the fair value of the liability at the end of each reporting period and at the date of settlement, with any changes in fair value recognized in profit or loss as share-based payments.

3.18.4 Termination benefits

Termination benefits are payable when employment is terminated by the Bank before the normal retirement date, or an employee’s decision to accept an offer of benefits in exchange for the termination of employment. The Bank recognizes a liability and expense for termination benefits at the earlier of the following dates; when the Bank can no longer withdraw the offer of those benefits and when the Bank recognizes costs for a restructuring that is within the scope of Korean IFRS No.1037 and involves the payment of termination benefits. If the termination benefits are not expected to be settled wholly before twelve months after the end of the annual reporting period, then the termination benefits are discounted to present value.

3.19 Income Tax Expense

Income tax expense comprises current tax expense and deferred income tax expense. Current and deferred income taxes are recognized as income or expense and included in profit or loss for the period, except to the extent that the tax arises from (a) a transaction or event which is recognized, in the same or a different period, outside profit or loss, either in other comprehensive income or directly in equity and (b) a business combination.

3.19.1 Current income tax

Current income tax is the amount of income tax payable (recoverable) in respect of the taxable profit (tax loss) for a period. A difference between the taxable profit and accounting profit may arise when income or expense is included in accounting profit in one period but is included in taxable profit in a different period. Differences may also arise if there is revenue that is exempt from taxation, or expense that is not deductible in determining taxable profit (loss). Current income tax liabilities for the current and prior periods are measured using the tax rates that have been enacted or substantively enacted by the end of the reporting period.

The Bank offsets current income tax assets and current income tax liabilities if, and only if, the Bank (a) has a legally enforceable right to offset the recognized amounts and (b) intends either to settle on a net basis, or to realize the asset and settle the liability simultaneously.

3.19.2 Deferred income tax

Deferred income tax is recognized, using the asset-liability method, on temporary differences arising between the tax-based amount of assets and liabilities and their carrying amount in the financial statements. Deferred income tax liabilities are recognized for all taxable temporary differences and deferred income tax assets are recognized for all deductible temporary differences to the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilized. However, deferred income tax liabilities are not recognized if they arise from the initial recognition of goodwill; deferred income tax assets and liabilities are not recognized if they arise from the initial recognition of an asset or liability in a transaction that is not a business combination, and at the time of the transaction, affects neither accounting nor taxable profit or loss.

The carrying amount of a deferred income tax asset is reviewed at the end of each reporting period. The Bank reduces the carrying amount of a deferred income tax asset to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of that deferred income tax asset to be utilized.

Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred income tax liabilities and deferred income tax assets reflects the tax consequences that would follow from the manner in which the Bank expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

The Bank offsets deferred income tax assets and deferred income tax liabilities if, and only if the Bank has a legally enforceable right to offset current income tax assets against current income tax liabilities and the deferred income tax assets and the deferred income tax liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities which intend either to settle current income tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred income tax liabilities or assets are expected to be settled or recovered.

3.19.3 Uncertain tax positions

Uncertain tax positions arise from tax treatments applied by the Bank which may be challenged by the tax authorities due to the complexity of the transaction or different interpretation of the tax laws, such as a claim for rectification, a claim for a refund related to additional tax or a tax investigation by the tax authorities. The Bank recognizes its uncertain tax positions in the financial statements in accordance with Korean IFRS No.1012 and Interpretation of Korean IFRS No.2123. The income tax asset is recognized if a tax refund is probable for taxes levied by the tax authority, and the amount to be paid as a result of the tax investigation and others is recognized as the current tax payable. However, penalty tax and additional refund on tax are regarded as penalty or interest and are accounted for in accordance with Korean IFRS No.1037.

3.19.4 Global Minimum Tax

The Bank is subject to the global minimum tax under Pillar 2 legislation and has applied the exemption from recognizing and disclosing related deferred tax.

3.20 Transactions with the Trust Accounts

The Bank accounts for trust assets separately from its own assets in accordance with the Financial Investment Services and Capital Markets Act. The borrowings from trust accounts represent transfer of funds in trust accounts into banking accounts. Such borrowings from trust accounts are recorded as receivables from the banking accounts in the trust accounts and as borrowings from trust accounts in the banking accounts. The Bank earns trust fees from the trust accounts for its management of trust assets and operations. The reserves for future profits and losses are set up in the trust accounts for profits and losses related to those trust funds with a guarantee of the principal or of the principal and a certain minimum rate of return in accordance with the relevant laws and regulations applicable to trust operations. The reserves are used to provide for the losses on such trust funds and, if the losses incurred are in excess of the reserves, the excess losses are compensation paid as a loss on trust management in other operating expenses and the trust accounts recognize the corresponding compensation as compensation from banking accounts.

3.21 Leases

The Bank as a lessor recognizes lease payments from operating leases as income on a straight-line basis over the lease term. Initial direct costs incurred in obtaining an operating lease are added to the carrying amount of the underlying asset and recognized as expense over the lease term on the same basis as lease income. The respective leased assets are included in the statement of financial position based on their nature.

A lessee is required to recognize a right-of-use asset (lease assets) representing its right to use the underlying leased asset and a lease liability representing its obligation to make lease payments. Assets and liabilities arising from a lease are initially measured at the present value.

Lease liabilities include the net present value of the following lease payments:

 

•

Fixed payments (including in-substance fixed payments), less any lease incentives receivable

 

•

Variable lease payments that depend on an index or a rate

 

•

Amounts expected to be payable by the lessee under residual value guarantees

 

•

The exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and

 

•

Payments of penalties for terminating the lease, if the lease term reflects the lessee exercising an option to terminate the lease

The lease payments are discounted using the interest rate implicit in the lease if that rate can be readily determined. If that rate cannot be readily determined, the lessee’s incremental borrowing rate is used, which is the rate of interest that a lessee would have to pay to borrow over a similar term, and with a similar security, the funds necessary to obtain an asset of a similar value to the right-of-use asset in a similar economic environment.

Right-of-use assets are measured at cost comprising the following:

 

•

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

 

•

Any initial direct costs incurred by the lessee, and

 

•

An estimate of restoration costs

However, the Bank can elect not to apply the requirements of Korean IFRS No.1116 to short-term lease (lease that, at the commencement date, has a lease term of 12 months or less) and leases for which the underlying asset is of low value (for example, underlying leased asset under USD 5,000). The Bank applies the exemption of the standard for one time lease of real estate (for training purpose) and leases of low-value assets (underlying assets less than W 5 million or USD 5,000).

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.

For sale and leaseback transactions, the Bank applies the requirements of Korean IFRS No.1115 Revenue from Contracts with Customers, to determine whether the transfer of an asset is accounted for as a sale of that asset.

3.22 Operating Segments

The Bank identifies its operating segments based on internal reports which are regularly reviewed by the chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance. Segment information includes items which are directly attributable and can be allocated to the segment on a reasonable basis.

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 reporting purposes, the Bank considers all factors of credit risk exposure, such as default risk of individual borrowers, country risk, and risk of specific sectors. The Bank defines default as the definition applied to the calculation of Capital Adequacy Ratio under the new Basel Accord (Basel III).

4.2.2 Credit risk management

The Bank measures the expected loss and internal capital for the assets subject to credit risk management, including on-balance and off-balance sheet assets, and uses them as management indicators. The Bank 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 Bank level is introduced, applied, and managed to control the credit concentration risk.

All of the Bank’s loan customers (individuals and corporates) are assigned a credit rating and managed by a 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 the 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, the 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.

In order to establish a credit risk management system, the Bank manages credit risk by forming a separate risk management organization. In particular, independently of the Sales Group, the Credit Management & Analysis Group, Retail Customer Group and SME/SOHO Customer Group are in charge of loan policy, loan system, credit rating, credit analysis, follow-up management, and corporate restructuring. The Risk Management Group 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 Bank maintains allowances for loan losses associated with credit risk of loans to manage its credit risk.

The Bank assesses expected credit losses and recognizes loss allowances of financial assets at amortized cost and financial assets at fair value through other comprehensive income (debt instruments). 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 Bank measures the expected credit losses of loans classified as financial assets at amortized cost by deducting allowances for credit losses in the statements of financial position. 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 statements of financial position.
