IMPORTANT NOTICE TO PROSPECTIVE INVESTORS

Prospective investors should be aware that certain intermediaries in the context of this offering of the Notes, including certain underwriters, are “capital market intermediaries” (“CMIs”) subject to Paragraph 21 of the SFC Code of Conduct for Persons Licensed by or Registered with the Securities and Futures Commission of Hong Kong (the “SFC Code”). This notice to prospective investors is a summary of certain obligations the SFC Code imposes on such CMIs, which require the attention and cooperation of prospective investors. Certain CMIs may also be acting as “overall coordinators” (“OCs”) for this offering and are subject to additional requirements under the SFC Code.

Prospective investors who are the directors, employees or major shareholders of The Korea Development Bank (the “Issuer”), a CMI or its group companies would be considered under the SFC Code as having an association (“Association”) with the Issuer, the CMI or the relevant group company. Prospective investors associated with the Issuer or any CMI (including its group companies) should specifically disclose this when placing an order for the Notes and should disclose, at the same time, if such orders may negatively impact the price discovery process in relation to this offering.

Prospective investors who do not disclose their Associations are hereby deemed not to be so associated. Where prospective investors disclose their Associations but do not disclose that such order may negatively impact the price discovery process in relation to this offering, such order is hereby deemed not to negatively impact the price discovery process in relation to this offering. Prospective investors should ensure, and by placing an order prospective investors are deemed to confirm, that orders placed are bona fide, are not inflated and do not constitute duplicated orders (i.e., two or more corresponding or identical orders placed via two or more CMIs). If a prospective investor is an asset management arm affiliated with any underwriter, such prospective investor should indicate when placing an order if it is for a fund or portfolio where the underwriter or its group company has more than a 50% interest, in which case it will be classified as a “proprietary order” and subject to appropriate handling by CMIs in accordance with the SFC Code and should disclose, at the same time, if such “proprietary order” may negatively impact the price discovery process in relation to this offering.

Prospective investors who do not indicate this information when placing an order are hereby deemed to confirm that their order is not a “proprietary order”. If a prospective investor is otherwise affiliated with any underwriter, such that its order may be considered to be a “proprietary order” (pursuant to the SFC Code), such prospective investor should indicate to the relevant underwriter when placing such order. Prospective investors who do not indicate this information when placing an order are hereby deemed to confirm that their order is not a “proprietary order”. Where prospective investors disclose such information but do not disclose that such “proprietary order” may negatively impact the price discovery process in relation to this offering, such “proprietary order” is hereby deemed not to negatively impact the price discovery process in relation to this offering.

Prospective investors should be aware that certain information may be disclosed by CMIs (including private banks) which is personal and/or confidential in nature to the prospective investor. By placing an order, prospective investors are deemed to have understood and consented to the collection, disclosure, use and transfer of such information by the underwriters and/or any other third parties as may be required by the SFC Code, including to the Issuer, any OCs, relevant regulators and/or any other third parties as may be required by the SFC Code, it being understood and agreed that such information shall only be used for the purpose of complying with the SFC Code, during the bookbuilding process for this offering. Failure to provide such information may result in that order being rejected.

SUMMARY OF THE OFFERING

This summary highlights selected information from this prospectus supplement and the accompanying prospectus and may not contain all of the information that is important to you. To understand the terms of our Notes, you should carefully read this prospectus supplement and the accompanying prospectus.

The Notes

We are offering US$1,000,000,000 aggregate principal amount of 4.125% notes due October 16, 2027 (the “Notes”).

The Notes will bear interest at a rate of 4.125% per annum, payable semi-annually in arrear on April 16 and October 16 of each year, beginning on April 16, 2025. Interest on the Notes will be computed based on a 360-day year consisting of twelve 30-day months. See “Description of the Notes—Payment of Principal and Interest.”

The Notes will be issued in minimum denominations of US$200,000 principal amount and integral multiples of US$1,000 in excess thereof. The Notes will be represented by one or more global securities registered in the name of a nominee of The Depository Trust Company (“DTC”), as depositary.

The payment of interest and the repayment of principal on the Notes will not be guaranteed by the Government.

We do not have any right to redeem the Notes prior to maturity.

Listing

Application will be made to the SGX-ST for the listing and quotation of the Notes on the SGX-ST. Settlement of the Notes is not conditioned on obtaining the listing. For so long as the Notes are listed on the SGX-ST and the rules of the SGX-ST so require, the Notes, if traded on the SGX-ST, will be traded in a minimum board lot size of S$200,000 (or its equivalent in foreign currencies). Accordingly, the Notes, if traded on the SGX-ST, will be traded in a minimum board lot size of US$200,000.

In addition, application will be made to list the Notes on the Luxembourg Stock Exchange and to have the Notes admitted to trading on the Euro MTF Market of the Luxembourg Stock Exchange. Application will also be made for listing of the Notes to the International Securities Market of the London Stock Exchange. No assurance can be given that such applications will be approved or that such listings will be maintained.

Form and Settlement

We will issue each series of the Notes in the form of one or more fully registered global notes, registered in the name of a nominee of DTC, as depositary. Except as described in the accompanying prospectus under “Description of the Securities—Description of Debt Securities—Global Securities,” the global notes will not be exchangeable for Notes in definitive registered form, and will not be issued in definitive registered form. Financial institutions, acting as direct and indirect participants in DTC, will represent your beneficial interests in the global notes. These financial institutions will record the ownership and transfer of your beneficial interest through book-entry accounts. You may hold your beneficial interests in the Notes through Euroclear Bank SA/NV (“Euroclear”) or Clearstream Banking, S.A. (“Clearstream”) if you are a participant in such systems, or indirectly through organizations that are participants in such systems. Any secondary market trading of book-entry interests in the Notes will take place through DTC participants, including Euroclear and Clearstream. See “Clearance and Settlement—Transfers Within and Between DTC, Euroclear and Clearstream”.

S-6

Further Issues

We may from time to time, without the consent of the holders of the Notes, create and issue additional debt securities with the same terms and conditions as either series of the Notes in all respects so that such further issue shall be consolidated and form a single series with the relevant series of the Notes. We will not issue any such additional debt securities unless such additional securities have less than a de minimis amount of original issue discount or such issuance would otherwise constitute a “qualified reopening” for U.S. federal income tax purposes.

Delivery of the Notes

We expect to make delivery of the Notes, against payment in same-day funds on or about October 16, 2024, which we expect will be the fifth business day following the date of this prospectus supplement, referred to as “T+5,” for the Notes. You should note that initial trading of the Notes may be affected by the T+5 settlement. See “Underwriting—Delivery of the Notes”.

Underwriting

KDB Asia Limited, one of the underwriters, is our affiliate and has agreed to offer and sell the Notes only outside the United States to non-U.S. persons. See “Underwriting—Relationship with the Underwriters”.

S-7

USE OF PROCEEDS

The net proceeds from the issue of the Notes, after deducting the underwriting discount but not estimated expenses, will be US$994,570,000. We will use the net proceeds from the sale of the Notes for our general operations, including extension of foreign currency loans and repayment of our maturing debt and other obligations.

S-10

Six Months Ended June 30, 2024

In the first half of 2024, we had net income ofW1,673.8 billion compared to net income ofW2,814.6 billion in the corresponding period of 2023, on a separate basis. The principal factors for the decrease in net income included:

• a significant decrease in reversal of impairment loss on investments in subsidiaries and associates toW374.3 billion in the first half of 2024 fromW1,044.9 billion in the corresponding period of 2023, primarily due to a comparatively smaller increase in the recoverable amount of our investment in Hanwha Ocean Co., Ltd. (formerly, DSME), resulting from a smaller increase in the fair value of such investment in the first half of 2024 compared to the corresponding period of 2023;

• a significant decrease in reversal of provisions for loan loss allowance toW69.1 billion in the first half of 2024 fromW636.7 billion in the corresponding period of 2023, primarily due to a decrease in the reversal of provisions for loan loss allowance for Hanwha Ocean Co., Ltd.;

• a decrease in net interest income toW562.8 billion in the first half of 2024 fromW874.2 billion in the corresponding period of 2023, due to an increase in interest expense toW5,562.5 billion in the first half of 2024 fromW4,699.2 billion in the corresponding period of 2023, which outpaced the increase in interest income toW6,125.2 billion in the first half of 2024 fromW5,573.4 billion in the corresponding period of 2023, primarily due to an increase in recent periods of the portion of low-interest loans provided pursuant to Government support programs as a percentage of our overall loans; and

• an increase in net loss on derivatives toW414.4 billion in the first half of 2024 fromW129.9 billion in the corresponding period of 2023, primarily due to a change in net gain (loss) on hedging purpose currency derivatives to a net loss in the first half of 2024 from a net gain in the corresponding period of 2023, resulting from fluctuations in interest rates, foreign exchange rates and the prices of derivatives.

The above factors were partially offset by the following factors:

• a decrease in income tax expense toW358.5 billion in the first half of 2024 fromW610.8 billion in the corresponding period of 2023, primarily due to a decrease in our profit before income taxes toW2,032.3 billion in the first half of 2024 fromW3,425.4 billion in the corresponding period of 2023; and

• an increase in net gain on foreign currency transactions toW571.4 billion in the first half of 2024 fromW356.9 billion in the corresponding period of 2023, primarily due to increased fluctuations in foreign currency exchange rates in the first half of 2024 compared to the corresponding period of 2023.

Allowances for Loan Losses and Loans in Arrears

As of June 30, 2024, we had established allowances ofW2,807.7 billion for loan losses under K-IFRS.

Certain of our customers have restructured loans with their creditor banks. As of June 30, 2024, we have provided loans ofW731.8 billion for companies under workout, court receivership, court mediation and other restructuring procedures. As of June 30, 2024, we had established allowances ofW307.0 billion for loan losses with respect to such companies. We cannot assure you that actual credit losses from the loans to these customers will not exceed the allowances established.

S-11

The following table provides information on our loan loss allowances.

		As of June 30,  2024(1)
		Loan Amount		Loan Loss Allowances
		(in billions of won, except percentages)
Loan Classification	Normal(2)	W	205,111.7	W	2,115.0
	Precautionary		484.0		89.4
	Substandard		496.4		173.8
	Doubtful		290.2		136.9
	Expected Loss		401.7		292.6
	Total	W	206,784.1	W	2,807.7

(1) These figures include loans for facility development, loans for working capital, loans for households, inter-bank loans, private loans, off-shore loan receivables, bills bought in foreign currencies, advance payments on acceptances and guarantees and other loans.

(2) Includes loans guaranteed by the Government. Under K-IFRS, we establish loan loss allowances for all loans including loans guaranteed by the Government.

As of June 30, 2024, our non-performing loans totaledW1,188.4 billion, representing 0.6% of our outstanding loans as of such date. Non-performing loans are defined as loans that are classified as substandard or below. On June 30, 2024, our legal reserve wasW3,725.5 billion, representing 1.8% of our outstanding loans as of such date.

Loans to Financially Troubled Companies

We have credit exposure to a number of financially troubled Korean companies including HMM Company Limited (formerly, Hyundai Merchant Marine Co., Ltd.), HJ Shipbuilding & Construction Co., Ltd. (formerly, Hanjin Heavy Industries and Construction Co., Ltd.), Daehan Shipbuilding Co., Ltd., K Shipbuilding Co., Ltd., GM Korea Company and Taeyoung E&C. As of June 30, 2024, our credit extended to these companies totaledW10,833.0 billion, accounting for 3.3% of our total assets as of such date.

The following table provides the loan amounts (including loans classified as substandard or below and equity investment classified as estimated loss or below) extended to these companies as of the dates indicated:

Company	As of December 31, 2023	As of June 30, 2024	Primary Reason for Change
	(billions of won)
HMM Company Limited	W6,549.4	W 7,362.1	Increase due to a reversal of impairment loss resulting from an increase in the value of shares of HMM Company Limited
HJ Shipbuilding & Construction	1,195.7	1,078.7	Decrease due to decreases in refund guarantees and working capital loans
Daehan Shipbuilding	977.2	1,074.8	Increase due to an increase in refund guarantees
K Shipbuilding	645.2	681.0	Increase due to an increase in refund guarantees
GM Korea Company	455.9	442.6	Decrease due to a decrease in the value of stocks
Taeyoung E&C	138.0	193.7	Increase due to increases in working capital loan and equity investment
Total	W 9,961.4	W10,833.0

S-12

As of June 30, 2024, we established allowances ofW0.8 billion for HMM Company Limited,W127.4 billion for HJ Shipbuilding & Construction,W70.9 billion for Daehan Shipbuilding,W40.5 billion for K Shipbuilding, none for GM Korea Company andW10.5 billion for Taeyoung E&C.

In July 2016, HMM Company Limited executed a debt-to-equity swap with us and other creditors, as part of its continued restructuring led by us as its largest creditor, and affiliates of the Hyundai group reduced their shareholdings in HMM Company Limited, which resulted in us becoming the largest shareholder of HMM Company Limited. In October 2018, we injectedW1 trillion in emergency aid into HMM Company Limited in order to normalize its operations by purchasing bonds with warrants and convertible bonds issued by HMM Company Limited. We also concurrently entered into an agreement to jointly manage HMM Company Limited together with Korea Ocean Business Corporation until December 2020, which was subsequently extended to January 2022. In June 2021, we exercised our right to convertW300 billion of our convertible bonds into 60 million common shares of HMM Company Limited. Following an improvement in the financial performance of HMM Company Limited, we ended our joint management of HMM Company Limited in January 2022, upon which Korea Ocean Business Corporation became its sole manager. We and Korea Ocean Business Corporation are each pursuing the sale of our respective equity shares in HMM Company Limited. In July 2023, we and Korea Ocean Business Corporation jointly announced a combined sale of an aggregate of approximately 38.9% of the equity interest in HMM Company Limited through a competitive bidding process. Although a consortium led by Harim Group was initially selected as the preferred bidder in December 2023, we concluded our negotiations with them in February 2024 upon failure to reach an agreement on certain commercial issues. In May and June 2024, we exercised our right to convertW100 billion andW50 billion of our convertible bonds into 20 million and 10 million common shares of HMM Company Limited, respectively. As of June 30, 2024, our equity stake in HMM Company Limited amounted to 30.9%.

In the first half of 2024, we sold non-performing loans worthW387.4 billion to Hana F&I Co., Ltd.

The Bank is engaged in the banking industry under The Korea Development Bank Act and other applicable statutes, and in the fiduciary in accordance with the Financial Investment Services and Capital Markets Act.

Korea Finance Corporation (“KoFC”), the former ultimate parent company, and KDB Financial Group Inc. (“KDBFG”), the former immediate parent company, were established by spin-offs of divisions of the Bank as of October 28, 2009. KoFC and KDBFG were merged into the Bank, effective as of December 31, 2014. Issued capital isW26,131,559 million with 5,226,311,768 shares of issued and outstanding as of June 30, 2024 and 100% of the Bank’s shares are owned by the government of the Republic of Korea.

2. Basis of Preparation

(1) Application of accounting standards

These interim financial statements have been prepared in accordance with the Korean International Financial Reporting Standards (“K-IFRS”) 1034 Interim Financial Reporting and provide less information as compared with its annual financial statements. The interim financial statements have been prepared in accordance with K-IFRS effective as of June 30, 2024 and the significant accounting policies applied in the preparation of these interim financial statements have been consistently applied to all periods presented unless otherwise specified.

(2) Changes and disclosures of accounting policies

(i) New and amended standards adopted

The Bank newly applied the following amended and enacted standards for the annual period beginning on January 1, 2024. The nature and the impact of each new standard or amendment are described below:

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

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

2. Basis of Preparation, Continued

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

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

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

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

Amendment of Korean IFRS No.1001 Presentation of Financial Statements—Disclosure of Virtual Asset

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

Amendments to Korean IFRS No.1012 Income Taxes—International Tax Reform—Pillar Two Model Rules

The Bank applies K-IFRS 1012 Income Taxes, which addresses income taxes arising from tax law enacted or substantively enacted to implement the Pillar Two model rules published by the Organization for Economic Co-operation and Development (“Pillar Two income taxes”). The amendments introduce a temporary exception to the requirements to recognize and disclose information about deferred tax assets and liabilities related to Pillar Two income taxes.

The Bank is still in the process of assessing the potential exposure to Pillar Two income taxes as of June 30, 2024, and expects no significant impact on the financial statements. Meanwhile, the recognition and disclosure of deferred taxes have been applied using the temporary exception.

(ii) New standards and interpretations issued but not effective

The following new standards, interpretations and amendments to existing standards have been issued but not effective for annual periods beginning after January 1, 2024, and the Bank has not early adopted them. The nature and the impact of each new standard, amendment and enactments are described below:

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

The amendments require the 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. This amendment will be applied to the financial statements for the accounting year beginning on or after January 1, 2025. These amendments do not have a significant impact on the financial statements.

2. Basis of Preparation, Continued

(3) Basis of measurement

The financial statements have been prepared on the historical cost basis except for the following material items in the statement of financial position:

• Derivative financial instruments measured at fair value

• Financial instruments measured at fair value through profit or loss

• Financial instruments measured at fair value through other comprehensive income

• Fair value hedged financial instruments with changes in fair value, due to hedged risks, recognized in profit or loss

• Liabilities for defined benefit plans, which are recognized as net of the total present value of defined benefit obligations less the fair value of plan assets.

(4) Functional and presentation currency

These financial statements are presented in Korean won (“W”), which is the Bank’s functional currency and the currency of the primary economic environment in which the Bank operates.

(5) Use of estimates and judgments

The preparation of the financial statements in conformity with K-IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Management’s estimates of outcomes may differ from actual outcomes if management’s estimates and assumptions based on management’s best judgment at the reporting date are different from the actual environment.

Estimates and assumptions are continually evaluated and any change in an accounting estimate is recognized prospectively by including it in profit or loss in the period of the change, if the change affects that period only.

The following are the key assumptions concerning the future and other key sources of estimation uncertainty at the end of the reporting period that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year:

(i) Fair value of financial instruments

Financial instruments measured at fair value through profit or loss and other comprehensive income, and derivative instruments are recognized and measured at fair value. If the market for a financial instrument is not active, 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, willing parties, if available, referencing to the current fair value of another instrument that is substantially the same, discounted cash flow analysis and option pricing models.

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 and assumptions in price determination and other risks.

(In millions of won)

2. Basis of Preparation, Continued

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.

(ii) Credit losses allowance

The Bank tests impairment and recognizes loss allowances on financial assets classified at amortized cost, debt instruments measured at fair value through other comprehensive income and recognizes provisions for payment guarantee, financial guarantee and unused commitments. Accuracy of allowances and provisions for credit losses is dependent upon estimation of expected cash flows of the borrower for individually assessed allowances of loans, and upon assumptions and methodology used for collectively assessed allowances for groups of loans, guarantees and unused loan commitments.

(iii) Deferred taxes

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date. Deferred income tax assets are recognised to the extent that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Actual income taxes in the future may not be identical to the recognised deferred tax assets and liabilities.

(iv) Defined benefit liabilities

The Bank operates a defined benefit plan. Defined benefit liability is calculated by annual actuarial valuations as of the reporting date. To perform the actuarial valuations, assumptions for discount rates, future salary increases and others are required to be estimated. Defined benefit plans contain significant uncertainties in estimations due to its long-term nature.

3. Significant Accounting Policies

The significant accounting policies applied by the Bank in preparation of its separate financial statements are included below. The accounting policies set out below have been applied consistently to all periods presented in these separate financial statements.

(1) Investments in subsidiaries and associates

The accompanying financial statements are separate financial statements in accordance with K-IFRS 1027 ‘Separate Financial Statements’ and investments in subsidiaries and associates are accounted for at cost, not by performance and net asset reported by the investee.

Dividends received from subsidiaries and associates are recognised as income as of the time the right to receive the dividends is established.

(2) Business combination of entities under common control

The assets and liabilities acquired under business combinations under common control are recognised at the carrying amounts recognised previously in the consolidated financial statements of the ultimate parent. The

difference between consideration transferred and carrying amounts of net assets acquired is recognised as part of share premium.

(3) Operating segments

The Bank makes decisions regarding allocation of resources to segments and categorizes segments, based on internal reports reviewed periodically by the chief operating decision maker, to assess performance. Information on segments reported to the chief operating decision maker includes items directly attributable to segments as well as those that can be allocated on a reasonable basis. Unallocated items mainly comprise corporate assets (such as the Bank Headquarters), head office expenses, and income tax assets and liabilities. The Bank recognises the CEO as the chief operating decision maker.

(4) Foreign exchange

(i) Foreign currency transactions

Transactions in foreign currencies are translated to the functional currency of the Bank, at exchange rates of the dates of transactions. Monetary assets and liabilities denominated in foreign currencies at the reporting date are translated to the functional currency at the exchange rate at that date. The foreign currency gain or loss on monetary items is the difference between amortized cost in the functional currency at the beginning of the period, adjusted for effective interest and payments during the period, and the amortized cost in foreign currency translated at the exchange rate at the end of the reporting period. Non-monetary assets and liabilities denominated in foreign currencies that are measured at fair value are translated to the functional currency at the exchange rate at the date that the fair value was determined.

Foreign currency differences arising on transactions and translations of monetary items are recognised in profit or loss, except for differences arising on the translation of a financial instruments designated as hedges of the net investment in foreign operations, or cash flow hedge, which are recognised in other comprehensive income.

When a gain or loss on a non-monetary item is recognised in other comprehensive income, any exchange component of that gain or loss is recognised in other comprehensive income. Conversely, when a gain or loss on a non-monetary item is recognised in profit or loss, any exchange component of that gain or loss shall be recognised in profit or loss.

(ii) Foreign operations

If the presentation currency of the Bank is different from a foreign operation’s functional currency, the financial statements of the foreign operation are translated into the presentation currency using the following methods:

Unless the functional currency of foreign operations is in a state of hyperinflation, assets and liabilities of foreign operations are translated at the closing exchange rate at the end of the reporting period. Revenues and expenses on the statement of comprehensive income are translated at the exchange rates of the date of transaction. Foreign currency differences that arise from translation are recognized as other comprehensive income, and the disposal of a foreign operation is re-categorized as profit or loss as of the moment of the disposal profit or loss is recognized.

(In millions of won)

3. Significant Accounting Policies, Continued

Any goodwill arising on the acquisition of a foreign operation, and any adjustments in fair value to the carrying amounts of assets and liabilities due to such acquisition, are treated as assets and liabilities of the foreign operation. Therefore, such are expressed in the functional currency of the foreign operations and, alongside other assets and liabilities of the foreign operation, translated at the closing exchange rate.

In the case of the disposal of a foreign operation, cumulative amounts of exchange difference regarding the foreign operation, recognized separately from other comprehensive income, are re-categorized from assets to profit or loss as of the disposal profit or loss is recognized.

(iii) Foreign exchange of net investment in foreign operations

Monetary items receivable from or payable to a foreign operation, with none or little possibility of being settled in the foreseeable future, are considered a part of the net investment in the foreign operation. Therefore, the exchange difference is recognised as comprehensive income or loss in the financial statement and re-categorized to profit or loss as of the disposal of the related net investment.

(5) Recognition and measurement of financial instruments

(i) Initial recognition

The Bank recognizes a financial asset or a financial liability in its separate statement of financial position when the Bank becomes a party to the contractual provisions of the instrument. A regular way purchase or sale of financial assets is recognized and derecognized using trade date accounting. The Bank classifies 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 on the basis of the Bank’s business model for managing the financial assets and the contractual cash flow characteristics of the financial assets. The Bank classifies financial liabilities as financial liabilities at fair value through profit or loss, or financial liabilities at amortized cost.

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.

(ii) Subsequent measurement

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

Amortized cost

The amortized cost 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.

Fair value

Fair values, which the Bank primarily uses for the measurement of financial instruments, are the published price quotations based on market prices or dealer price quotations of financial instruments traded in an active

market where available. These are the best evidence 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, an entity in the same industry, pricing service or regulatory agency, and those prices represent actual and regularly occurring market transactions on an arm’s length basis.

If the market for a financial instrument is not active, 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, willing parties, if available, referencing to 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. For more complex instruments, the Bank uses internally developed models, which are usually based on valuation methods and techniques generally used within the industry, or a value measured by an independent external valuation institution as the fair values if all or some of the inputs to the valuation models are not market observable and therefore it is necessary to estimate fair value based on certain assumptions.

If the valuation technique does not reflect all factors which market participants would consider in setting a price, the fair value is adjusted to reflect those factors. Those factors include counterparty credit risk, bid-ask spread, liquidity risk and others.

The chosen valuation technique makes maximum use of market inputs and relies as little as possible on entity-specific inputs. It incorporates all factors that market participants would consider in setting a price 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.

(iii) Derecognition

Derecognition is the removal of a previously recognized financial asset or financial liability from the statement of financial position. The Bank derecognizes a financial asset or a financial liability when, and only when:

Derecognition of financial assets

Financial assets are derecognized when the contractual rights to the cash flows from the financial assets expire or the financial assets have been transferred and substantially all the risks and rewards of ownership of the financial assets are also transferred, or all the risks and rewards of ownership of the financial assets are neither substantially transferred nor retained and the Bank has not retained control. If the Bank neither transfers nor disposes of substantially all the risks and rewards of ownership of the financial assets, 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.

(In millions of won)

3. Significant Accounting Policies, Continued

Derecognition of financial liabilities

Financial liabilities are derecognized from the statement of financial position when the obligation specified in the contract is discharged, cancelled or expires.

(iv) Offsetting

Financial assets and liabilities are offset and the net amount reported in the separate statements of financial position where there is a legally enforceable right to offset the recognized amounts and there is an intention to settle on a net basis or realize the assets and settle the liability simultaneously.

(6) Cash and cash equivalents

Cash and cash equivalents comprise balances with original maturities of three months or less from the date of acquisition that are subject to an insignificant risk of changes in their fair value, including cash on hand, deposits held at call with banks and other highly liquid short-term investments with original maturities of three months or less.

(7) Non-derivative financial assets

(i) Financial assets at fair value through profit or loss

Any non-derivative financial asset classified as held for trading or not classified as financial assets at fair value through other comprehensive income or financial assets measured at amortized cost is categorized under financial assets at fair value through profit or loss.

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 the fair value are recognized in profit or loss. Interest income and dividend income from financial assets at fair value through profit or loss are also recognized in profit or loss.

(ii) Financial assets at fair value through other comprehensive income

The Bank classifies financial assets as financial assets at fair value through other comprehensive income if they meet the following conditions: 1) debt instruments that are a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets, and consistent with representing solely payments of principal and interest on the principal amount outstanding or 2) equity instruments, not held for trading with the objective of generating a profit from short-term fluctuations in price or dealer’s margin, designated as financial assets at fair value through other comprehensive income. After initial recognition, a financial asset at fair value through other comprehensive income is measured at fair value. Gain and loss from changes in fair value, other than dividend income and interest income amortized using effective interest method and exchange differences arising on monetary items which are recognized directly in profit or loss, are recognized as other comprehensive income in equity.

(In millions of won)

3. Significant Accounting Policies, Continued

At disposal of financial assets at fair value through other comprehensive income, cumulative gain or loss is recognized as profit or loss for the reporting period. However, cumulative gain or loss of equity instrument designated as fair value through other comprehensive income are not recycled to profit or loss at disposal.

Financial assets at fair value through other comprehensive income denominated in foreign currencies are translated at the closing rate. Exchange differences resulting from changes in amortized cost are recognized in profit or loss, and other changes are recognized as equity.

(iii) Financial assets measured at amortized cost

A financial asset, which are held within the business model whose objective is to hold assets in order to collect contractual cash flows and consistent with representing solely payments of principal and interest on the principal amount outstanding, are classified as a financial asset at amortized cost. Financial assets at amortized cost are subsequently measured at amortized cost using the effective interest method after initial recognition and interest income is recognized using the effective interest method.

(8) Expected credit loss of financial assets

The Bank measures expected credit loss and recognizes loss allowance at the end of the reporting period for financial assets measured at amortized cost and fair value through other comprehensive income with the exception of financial asset measured at fair value through profit or loss.

The expected credit loss (“ECL”) is the weighted average amount of possible outcomes within a certain range, reflecting the time value of money, estimates on the past, current and future situations, and information accessible without excessive cost of effort.

The Bank uses the following three measurement techniques in accordance with K-IFRS:

• General approach: for financial assets and off-balance-sheet unused credit line that are not applied below two approaches

• Simplified approach: for receivables, contract assets and lease receivables

• Credit-impaired approach: for purchased or originated credit-impaired financial assets

The general approach is applied differently depending on the significance of the increase of the credit risk. If, at the reporting date, the credit risk on a financial instrument has not increased significantly since initial recognition, an entity shall measure the loss allowance for that financial instrument at an amount equal to 12-month expected credit losses. If the credit risk on that financial instrument has increased significantly since initial recognition, an entity shall measure the loss allowance for a financial instrument at an amount equal to the lifetime expected credit losses at each reporting date.

The Bank applies the simplified approach to 1) trade receivables and contract assets that do not have a significant financing component or 2) trade receivables, contract assets and lease receivables upon determining the Bank’s accounting policies as the application of the simplified approach. The approach requires expected lifetime losses to be recognized from initial recognition of the financial assets. Under credit-impaired approach, the Bank shall only recognize the cumulative changes in lifetime expected credit losses since initial recognition as a loss allowance for purchased or originated credit-impaired financial assets.

3. Significant Accounting Policies, Continued

The following non-exhaustive list of information may be relevant in assessing changes in credit risk:

• Significant changes in internal price indicators of credit risk as a result of a change in credit risk since inception

• Other changes in the rates or terms of an existing financial instrument that would be significantly different if the instrument was newly originated or issued at the reporting date

• An actual or expected significant change in the financial instrument’s external credit rating

• An actual or expected internal credit rating downgrade for the borrower or decrease in behavioural scoring used to assess credit risk internally

• An actual or expected significant change in the operating results of the borrower

• Past due information

(i) Forward-looking information

The Bank uses forward-looking information, when it determines whether the credit risk has increased significantly since initial recognition and measures expected credit losses.

The Bank assumes the risk component has a certain correlation with the business cycle, and calculates the expected credit loss by reflecting the forward-looking information with macroeconomic variables on the measurement inputs.

Forward looking information used in calculation of expected credit loss is derived after comprehensive consideration of a variety of factors including scenario in management planning, worst-case scenario used for stress testing, third party forecast, and others.

(ii) Measuring expected credit losses on financial assets at amortized cost

The amount of the loss on financial assets at amortized cost is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows discounted at the financial asset’s original effective interest rate. The Bank estimates expected future cash flows for financial assets that are individually significant (individual assessment of impairment).

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

Individual assessment of impairment

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

Collective assessment of impairment

Collective assessment of loss allowance involves historical loss experience along with incorporation of forward-looking information. Such process incorporates factors such as type of collateral, product and borrowers, credit rating, size of portfolio and recovery period and applies probability of default on a group of assets and loss

given default by type of recovery method. Also, the expected credit loss model involves certain assumption to determine input based on loss experience and forward-looking information. These models and assumptions are periodically reviewed to reduce gap between loss estimate and actual loss experience.

The expected credit loss for financial assets measured at amortized cost is recognized as the loss allowance, and when the financial asset is determined to be irrecoverable, the carrying amount and loss allowance are decreased. If financial assets previously written off are recovered, the loss allowance is increased and the difference is recognized in the current profit or loss.

(iii) Measuring expected credit losses on financial assets at fair value through other comprehensive income

Measuring method of expected credit losses on financial assets at fair value through other comprehensive income is equal to the method of financial assets at amortized cost, except for changes in loss allowances that are recognized as other comprehensive income. Amounts recognized in other comprehensive income for sale or repayment of financial assets at fair value through other comprehensive income are reclassified to profit or loss.

(9) Derivative financial instruments including hedge accounting

Derivative financial instruments are initially recognised at fair value at the inception of the contract and re-estimated at fair value subsequently. The recognition of profit or loss due to changes in fair value of derivative instruments is as described below:

(i) Hedge accounting

Derivative financial instruments are accounted differently depending on whether hedge accounting is applied, and therefore, are classified into trading purpose derivatives and hedging purpose derivatives.

Upon the transaction of hedging purpose derivatives, two different types of hedge accounting are applied; a fair value hedge, and a cash flow hedge. A fair value hedge is a hedge of the exposure to changes in fair value of a recognised asset or liability or an unrecognised firm commitment, or an identified portion of such an asset, liability or firm commitment, that is attributable to a particular risk and could affect profit or loss. A cash flow hedge is a hedge of the exposure to variability in cash flows that (i) is attributable to a particular risk associated with a recognised asset or liability (such as all or some future interest payments on variable rate debt) or a highly probable forecast transaction and (ii) could affect profit or loss.

At the inception of the hedge relationship, the Bank formally documents the relationship between the hedged item and the hedging instrument, including the nature of the risk, the objective and strategy for undertaking the hedge, and the method that will be used to assess the effectiveness of the hedging relationship.

Fair value hedge

For designated and qualifying fair value hedges, the change in the fair value of a hedging derivative is recognised in profit or loss in the statement of comprehensive income. Meanwhile, the change in the fair value of the hedged item, attributable to the risk hedged, is recorded as part of the carrying value of the hedged item and is also recognised in profit or loss in the statement of comprehensive income. When the hedge no longer meets the criteria for hedge accounting, the hedge relationship is terminated. For hedged item recorded at amortized

3. Significant Accounting Policies, Continued

cost, the difference between the carrying value of the hedged item on termination and the face value is amortized over the remaining term of the original hedge using the EIR.

Cash flow hedge

For designated and qualifying cash flow hedges, the effective portion of gain or loss on the hedging instruments is initially recognised directly in equity. The ineffective portion of the gain or loss on the hedging instrument is recognised immediately in the statement of comprehensive income. When the hedged cash flow affects the profit or loss in statement of comprehensive income, the gain or loss on the hedging instrument is recorded in the corresponding income or expense line in profit or loss in the statement of comprehensive income.

When a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognised when the hedged forecasted transaction is ultimately recognised in the statement of comprehensive income. When a forecasted transaction is no longer expected to occur, the cumulative gain and loss that was reported in equity is immediately transferred to profit or loss in the statement of comprehensive income.

Hedges of net investments in foreign operations

The Bank designates non-derivative financial instruments as hedging instruments for foreign currency risk arising from net investments in foreign operations and recognises the portion of the gain or loss on the hedging instrument that is determined to be an effective hedge in other comprehensive income. The cumulative amounts recognised in other comprehensive income relating to both the foreign exchange differences arising on translation of the results and financial position of the foreign operation and the gain or loss on the hedging instrument that is determined to be an effective hedge of the net investment are reclassed from equity to profit or loss as a reclassification adjustment when the Bank disposes of the foreign operation.

(ii) Trading purpose derivatives

For trading purpose derivatives transaction, changes in the fair value of derivatives are recognised in net income.

(10) Day one profit or loss recognition

For financial instruments classified as level 3 on the fair value level hierarchy measured using assess variables not observable in the market, the difference between the fair value at initial recognition and the transaction price, which is equivalent to Day one profit or loss, is amortized by using the straight-line method over time.

(11) Property and equipment

The Bank’s property and equipment are recognised at the carrying amount at historical costs less accumulated depreciation and accumulated impairment in value. Historical costs include the expenditures directly related to the acquisition of assets.

Subsequent costs are recognised in the carrying amount of assets or, if appropriate, as separate assets if the probabilities future economic benefits associated with the assets will flow into the Bank and the costs can be

measured reliably; the carrying amount of the replaced part is derecognised. Furthermore, any other repairs or maintenances are charged to profit or loss as incurred.

Land is not depreciated. Depreciation on other assets is calculated using the straight-line method to the amount of residual value less acquisition cost over the following estimated useful lives:

Type	Useful lives (years)
Buildings	20 ~ 50
Structure	10 ~ 40
Movable property	4

Property and equipment are impaired when the carrying amount exceeds the recoverable amount. The Bank assesses residual value and economic life of its assets at each reporting date and adjusts useful lives when necessary. Any gain or loss arising from the disposal of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is recognised in non-operating income (expense) in the statement of comprehensive income.

(12) Investment property

The Bank classifies property held for rental income or benefits from capital appreciation as investment property. Investment property is measured initially at cost, including transaction costs. Subsequent to initial recognition, the cost model is applied. Subsequent to initial recognition, an item of investment property is carried at its cost less any accumulated depreciation and any accumulated impairment loss.

Investment properties are derecognised either when they have been disposed of or when the investment property is permanently withdrawn from use and no future economic benefit is expected from its disposal. The difference between the net disposal proceeds and the carrying amount of the asset is recognised in the statement of comprehensive income in the period of de-recognition. Reclassification to other account is made if there is a change in use of corresponding investment property.

Depreciation of investment property is calculated using the straight-line method over its estimated useful lives as follows:

Type	Useful lives (years)
Buildings		20 ~ 50
Structure		10 ~ 40

(13) Intangible assets

An intangible asset is recognised only when its cost can be measured reliably, and the probabilities future economic benefits from the asset will flow into the Bank are high. Separately acquired intangible assets are recognised at the acquisition cost, and subsequently, the cost less accumulated depreciation and accumulated impairment is recognised as the carrying amount.

Intangible assets with finite lives are amortized over the four-year to 30-year period of useful economic lives using the straight-line method. At the end of each reporting period, the Bank reviews intangible assets for any evidence that indicate impairment, and upon the presence of such evidence, the Bank estimates the amount recoverable and recognises the loss accordingly.

(In millions of won)

3. Significant Accounting Policies, Continued

Intangible assets with indefinite useful lives are not amortized but are tested for impairment annually. Furthermore, the Bank reviews such intangible assets to determine whether it is appropriate to consider these assets to have indefinite useful lives. If in the case the Bank concludes an asset is not qualified to be classified as non-finite, prospective measures are taken to consider such an asset as finite.

(14) Leases

The Bank recognizes a right-of-use asset representing its right to use the underlying leased asset and a lease liability representing its obligation to make lease payments at the commencement date of the lease. The Bank elected not to apply the requirements to the short-term leases and leases of low value assets.

Right-of-use asset

The right-of-use asset is measured at its cost less subsequent accumulated depreciation and accumulated impairment loss with adjustments reflected arising from remeasurements of the lease liability. The cost of the right-of-use asset comprise the amount of the initial measurement of the lease liability, any initial direct costs incurred by the lessee and any lease payments made at or before the commencement date, less any lease incentive received. The right-of-use asset is depreciated over the shorter of the asset’s useful life and the lease term on a straight-line basis from the commencement date of the lease.

Lease liabilities

At the commencement date, the lease liability is measured at present value of the lease payments that are not paid at that date. Lease payments include 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 variable lease payments that do not depend on an index or a rate are recognized as an expense in the period in which the event or condition that triggers those payments occurs.

When measuring the present value, the lease payments are discounted using the interest rate implicit in the lease. If such implicit rate cannot be readily determined, the Bank uses the Bank’s incremental borrowing rate. The lease liability is subsequently increased by the amount of interest expenses recognized on the lease liability and reduced by the lease payments made.

Short-term lease and lease of low-value assets

The Bank does not apply the requirements of lessee accounting to short-term leases and leases of low-value assets. The Bank recognizes the lease payments associated with these leases as expenses on a straight-line basis over the lease term.

(15) Impairment of non-financial assets

The Bank tests for any evidence of impairment in assets and reviews whether the impairment has taken place by estimating the recoverable amount, at the end of each reporting period. The recoverable amount is the higher of the fair value less cost and value in use of an asset.

S-37

Korea Development Bank

Notes to the Interim Separate Financial Statements

June 30, 2024 and 2023 (Unaudited), and December 31, 2023

(In millions of won)

3. Significant Accounting Policies, Continued

Except for impairment losses in respect of goodwill which are never reversed, an impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. The reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount, nor exceeds the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognised for the asset in prior years.

(16) Assets held for sale

Non-current assets, or disposal groups comprising assets and liabilities, that are expected to be recovered primarily through sale rather than through continuing use, are classified as held for sale. To be classified as held for sale, the asset (or disposal group) must be available for immediate sale in its present condition and its sale must be highly probable. The assets or disposal group that are classified as assets held for sale are measured at the lower of their carrying amount and fair value less cost to sell. The Bank recognizes an impairment loss for any initial or subsequent write-down of an asset (or disposal group) to fair value less costs to sell, and a gain for any subsequent increase in fair value less costs to sell, up to the cumulative impairment loss previously recognized.

Non-current assets that are classified as held for sale or part of a disposal group classified as held for sale are not depreciated (or amortized).

(17) Non-derivative financial liabilities

The Bank classifies non-derivative 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 liability. The Bank recognizes these financial liabilities in the statement of financial position when the Bank becomes a party to the contractual provisions of the financial liability.

(i) Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated at FVTPL upon initial recognition. Financial liabilities and derivatives are classified as financial instruments held for trading if they are acquired for repurchasing soon. Financial liabilities are classified as financial liabilities at FVTPL upon initial recognition, if the profit or loss from the liabilities indicates to be more purpose-appropriate to be recognised as profit or loss. Financial liabilities at FVTPL are designated at fair value in subsequent measurements, and any related un-realized profit or loss is recognised as profit or loss. In addition, for the amount of change in the fair value of the financial liability that is attributable to changes in the credit risk of that liability, the Bank present this change in other comprehensive income, and does not recycle this other comprehensive income to profit or loss, subsequently.

(ii) Financial liabilities measured at amortized cost

Financial liabilities measured at amortized cost are recognised at fair value less cost less transaction cost upon initial recognition, and subsequently at amortized costs. The difference between the proceeds (net of transaction cost) and the redemption value is recognised in the statement of comprehensive income over the periods of the liabilities using the effective interest method.

3. Significant Accounting Policies, Continued

Fees paid on the establishment of a loan facility are recognised as transaction costs of the loan, if the probability that some or all the facility will be drawn down is high. If, however, there is not enough evidence to conclude a draw-down of some or all the facility will occur, the fee is capitalized as a prepayment for liquidity services and amortized over the period of the facility to which it relates.

(18) Employee benefits

(i) Short-term employee benefits

Short-term employee benefits are employee benefits that are due to be settled wholly before 12 months after the end of the period in which the employees render the related service. When an employee has rendered service to the Bank during an accounting period, the Bank recognises the undiscounted amount of short-term employee benefits expected to be paid in exchange for that service.

(ii) Retirement benefits: defined contribution plans

A defined contribution plan is a pension plan under which the Bank pays fixed contributions into a separate fund. The Bank is no longer responsible for any foreseeable future liability after a certain amount or percentage of money is set aside for defined contribution plans. If the pension plan allows for early retirement, payments are recognised as employee benefits. If the contribution already paid exceeds the contribution due for service before the end of the reporting period, the Bank recognises that excess as an asset to the extent that the prepayment will lead to a reduction in future payments or a cash refund.

(iii) Retirement benefits: defined benefit plans

The Bank classifies all the pensions as defined benefit plans except defined contribution plans. The Bank’s net obligation in respect of defined benefit plans is calculated by estimating the amount of future benefit that employees have earned in the current and prior periods, discounting that amount and deducting the fair value of any plan assets. The calculation of defined benefit obligations is performed annually by a qualified actuary using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid and have terms to maturity like the terms of the related pension liability.

Remeasurements of the net defined benefit liabilities (assets), which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognised immediately in other comprehensive income.

(19) Provisions

Provisions are recognized when the Bank has a present legal or constructive obligation because of a past event, 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.

(20) Financial guarantees

Financial guarantee contracts are contracts that require the issuer (the Bank) to make specified payments to reimburse the holder for a loss it incurs because a specified debtor fails to make payments when due, in

3. Significant Accounting Policies, Continued

accordance with the original or changed terms of a debt instrument. Financial guarantees are initially recognized in the financial statements at fair value on the date the guarantee was given. Subsequent to initial recognition, the Bank’s liabilities under such guarantees are measured at the higher of:

• The amount determined in accordance with K-IFRS 1109 ‘Financial Instruments’ and

• The initial amount recognized, less, when appropriate, cumulative amortization recognized in accordance with K-IFRS 1115 ‘Revenue from Contracts with Customers’.

(21) Securities under resale or repurchase agreements

Securities purchased under agreements to resell are recorded as other loans and receivables and the related interest from these securities is recorded as interest income; securities sold under agreements to repurchase are recorded as other borrowings, and the related interest from these securities is recorded as interest expense.

(22) Interest income and expense

Interest income and expense are recognized in profit or loss using the effective interest method. The effective interest method measures the amortized costs of financial instruments and allocates the interest income or expense during the related period.

Upon the calculation of the effective interest rate, the Bank estimates future cash flows by taking into consideration all contractual terms of the financial instrument, but not future credit loss. The calculation also reflects any fees or points paid or received, transaction costs and any related premiums or discounts. In the case that the cash flow and expected duration of a financial instrument cannot be estimated reliably, the effective interest rate is calculated by the contractual cash flow during the contract period.

Once an impairment loss has been recognized on a financial asset or a group of similar assets, subsequent interest income is recognized on the interest rate that was used to discount future cash flow for measuring the impairment loss.

(23) Fees and commission income

Fees and commission income and expense are classified as follows according to related regulations:

(i) Fees and commission from financial instruments

Fees and commission income and expense that are integral to the effective interest rate on a financial asset or liability are included in the measurement of the effective interest rate. It includes those related to evaluation of the borrowers’ financial status, guarantee, collateral, other agreements and related evaluation as well as business transaction, rewards for activities, such as document preparation and recording and setup fees incurred during issuance of financial liabilities. However, when financial instruments are classified as financial instruments at fair value through profit or loss, fees and commission are recognized as revenue upon initial recognition.

(ii) Fees and commission from services

Fees and commission income charged in exchange for services to be performed during a certain period of time such as asset management fees, consignment fees and assurance service fees are recognized as the related

services are performed. When a loan commitment is not expected to result in the draw-down of a loan and K-IFRS 1039 ‘Financial Instrument: Recognition and Measurement’ is not applied for the commitment, the related loan commitment fees are recognized as revenue proportionally to time over the commitment period.

(iii) Fees and commission from significant transaction

Fees and commission from significant transactions, such as trading stocks and other securities, negotiation and mediation activities for third parties, for instance business transfer and takeover, are recognized when transactions are completed.

(24) Dividend income

Dividend income is recognized upon the establishment of the Bank’s right to receive the payment.

(25) Income tax expense

Income tax expense comprises current and deferred income tax. Current income tax and deferred income tax are recognized in profit or loss except to the extent that the tax arises from a transaction or event, which is recognized in other comprehensive income or directly in equity, or a business combination.

The Bank recognizes deferred income tax liabilities for all taxable temporary differences associated with investments in subsidiaries, associates, except to the extent that the Bank can control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. The Bank recognizes deferred income tax assets for all deductible temporary differences arising from investments in associates, to the extent that it is probable that the temporary difference will reverse in the foreseeable future and taxable profit will be available against which the temporary difference can be utilized.

Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply to the reporting period when the assets are realized, or the liabilities 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 assets and liabilities reflects the income tax effects 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 carrying amount of a deferred income tax asset is reviewed at the end of each reporting period and reduced 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 off-set only if the Bank has a legally enforceable right to off-set the related current income tax assets and liabilities, and the assets and liabilities relate to income tax levied by the same tax authority and are intended to be settled on a net basis.

(26) Accounting for trust accounts

The Bank, for financial reporting, differentiates trust assets from identifiable assets according to the Financial Investment Services and Capital Markets Act. Furthermore, the Bank receives trust fees from the application, management and disposal of trust assets, and appropriates such amounts for fees from trust accounts.

(In millions of won)

3. Significant Accounting Policies, Continued

Meanwhile, in the case the fee from an unspecified principal or interests guaranteed money in trust does not meet the principal or interest amount, even after appropriating deficit with trust fees and special reserve, the Bank fills in the remaining deficit in the trust account and appropriates such amounts for losses on trust accounts.

(27) Regulatory reserve for credit losses

When the total sum of allowance for possible credit losses is lower than the amount prescribed in Article 29(1) of the Regulations on Supervision of Banking Business, the Bank records the difference as regulatory reserve for credit losses at the end of each reporting period.

In the case that the existing regulatory reserve for credit losses exceeds the amount needed to be set aside at the reporting date, the surplus may be reversed. Furthermore, in the case that undisposed deficit exists, regulatory reserve for credit losses is saved from the time the undisposed deficit is disposed.

(28) Earnings per share

The Bank represents its diluted and basic earnings per common share in the separate statement of comprehensive income. Basic earnings per share (EPS) is calculated by dividing net profit attributable to shareholders of the Bank by the weighted average number of common shares outstanding during the reporting period. Diluted earnings per share is calculated by adjusting net profit attributable to common shareholders of the Bank, considering dilution effects from all potential common shares, and the weighted average number of common shares outstanding.

(29) Corrections of errors

Prior period errors shall be corrected by retrospective restatement in the first set of financial statements authorised for issue after their discovery except to the extent that it is impracticable to determine either the period-specific effects or the cumulative effect of the error.

10. Derivative Financial Instruments

The Bank’s derivative financial instruments consist of trading derivatives and hedging derivatives, depending on the nature of each transaction. The Bank enters into hedging derivative transactions mainly for the purpose of hedging risk related to changes in fair values of the underlying assets and liabilities and future cash flows.

The Bank enters into trading derivative transactions such as futures, forwards, swaps and options for arbitrage transactions by speculating on the future value of the underlying asset. Derivatives held-for trading transactions include contracts with the Bank’s clients and its liquidation position.

For the purpose of hedging the exposure to the variability of fair values and cash flows of funds in Korean won by changes in interest rate, the Bank mainly uses interest swaps or currency swaps. The main counterparties are foreign financial institutions and local banks. In addition, to hedge the exposure to the variability of fair values of bonds in foreign currencies by changes in interest rate or foreign exchange rate, the Bank mainly uses interest swaps or currency swaps.

The Bank applies net investment hedge accounting by designating non-derivative financial instruments as hedging instruments and any gain or loss on the hedging instruments relating to the effective portion of the hedge is recognised in other comprehensive income and accumulated in the foreign currency translation reserve.

Gains and losses on the hedging instrument accumulated in the foreign currency translation reserve are reclassified to profit or loss on the disposal or partial disposal of the foreign operation.

(*1) The investees are financed by the Bank and managed by KDB Infrastructure Investments Asset Management Co., Ltd. They were included in the scope of consolidation even though the Bank holds less than half of the voting rights because the Bank is exposed to variable returns and has the ability to affect those returns through its power over the investee.

(*2) Although the Bank’s shareholding in the investee is less than 50%, it controls the investee since it is exposed, or has right to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee.

(*3) Although the Bank’s shareholding is less than 20%, the Bank has significant influence considering the right to elect the investees’ directors and the Bank classifies the companies as associates.

(*4) Although the Bank’s shareholding is less than 20%, as the main creditor bank, the Bank have initiated management procedures that designate the Bank as the managing institution. Consequently, the Bank have acquired significant influence, such as the ability to participate in the financial and operating policies of the company, and have classified it as an associate.

16. Financial Liabilities Measured at FVTPL

(1) Financial liabilities designated at fair value through profit or loss as of June 30, 2024 and December 31, 2023 are as follows:

	June 30, 2024		December 31, 2023

Changes in fair value of structured debentures and deposits which hedge accounting are applied, are recognized in profit or loss, but structured debentures with no hedge accounting applied to, are measured at amortized costs. Therefore, such structured debentures and deposits, not applied to hedge accounting, have been designated at FVTPL to eliminate mismatch in measurements of accounting profit and loss.

(2) The difference between the carrying amount and contractual cash flow amount of financial liabilities designated at fair value through profit or loss as of June 30, 2024 and December 31, 2023 are as follows:

The Bank classifies and discloses fair value of the financial instruments into the following three-level hierarchy:

• Level 1: Financial instruments measured at quoted prices from active markets are classified as level 1.

• Level 2: Financial instruments measured using valuation techniques where all significant inputs are observable market data are classified as level 2.

• Level 3: Financial instruments measured using valuation techniques where one or more significant inputs are not based on observable market data are classified as level 3.

of increase in property disposal price (-1~1%), only when they consist of real properties. Other than that, it is difficult to measure the sensitivity amounts of beneficiary certificates for practical reasons. Also, for financial instruments categorized within level 3 as of June 30, 2024 and December 31, 2023,W23,801,542 million andW21,479,411 million, respectively, are excluded from the sensitivity disclosure because it is impossible to calculate the sensitivity due to changes in unobservable variables for practical reasons.

(*2) Sensitivity amounts of loans measured at FVTPL and derivatives financial instruments are calculated by increasing and decreasing the correlation coefficient and volatility (-10~10%) which are significant unobservable inputs.

(2) Fair value hierarchy of financial instruments measured at amortized cost

(i) The Bank’s policies for measuring fair value of financial instruments at amortized costs are as follows:

- Cash and due from banks: Fair value of cash is considered equivalent to the carrying amount. In the case of due from banks on demand, which do not have a set maturity and can be realized instantly, the carrying amount is a close estimate of the fair value and is assumed so. In the case of other ordinary due from banks, the cash flow discount method is used to estimate the fair value.

- Securities measured at amortized cost: The fair value of securities measured at amortized cost is computed by widely-accepted appraisal agencies upon request.

- Loans measured at amortized cost: The fair value of loans measured at amortized cost is the expected future cash flows, reflecting premature redemption ratio, discounted by the market interest rate, adjusted by a spread sheet considering the probability of default. Exceptions to this method include loans with credit line facilities, loans with a maturity of three months or less left and impaired loans, which the Bank assumes the carrying amount as the fair value.

- Deposits: The fair value of deposits is computed using the discounted cash flow method. However, for deposits, whose cash flows cannot be estimated reasonably, the Bank assumes the carrying amount as the fair value.

- Borrowings: The fair value of industrial financial debentures is computed using the discounted cash flow method by the Bank’s Fair Value Evaluation System. However, for borrowings including call money whose contractual maturity is three months or less, the Bank assumes the carrying amount as the fair value.

- Debentures: The fair value of industrial financial debentures is computed using the discounted cash flow method by the Bank’s Fair Value Evaluation System.

- Other financial assets and liabilities: The fair value of other financial assets and liabilities is computed using the discounted cash flow method. However, in cases cash flow cannot be estimated reasonably, the Bank assumes the carrying amount as the fair value.

(vii) Response to Basel

The Korean financial authorities have implemented Basel II since January 2008, and the Standardized Approach and the Foundation Internal Ratings-Based Approach for calculating credit risk are applicable.

In conformity with the implementation roadmap of Basel II, the Bank obtained the approval to use the Foundation Internal Ratings-Based Approach on credit risk from the FSS in July 2008 and has applied the approach since late June 2008. The Bank applies the Standardized Approach on market risks and operational risks.

The Bank completed the Basel III standard risk management system in preparation of the adoption of the Basel III regulations announced on December 1, 2013. Starting from 2013 year-end, the BIS capital adequacy ratio has been measured in accordance to the Basel III regulations.

Responding to the requirements of the financial authorities, the Bank recognizes interest rate risk, liquidity risk, credit bias risk and reputation risk besides Pillar I risks (credit risk, market risk and operational risk). The Bank has actively responded to the Pillar 2 regulation, including additional capital requirements based on comprehensive assessment of risk management levels since 2015. In addition, from the end of 2015, the Bank has applied the uniform standards for the public announcement of financial business for Basel compliance.

The Bank completed revised standards such as capital requirements for banks’ investments in funds in 2017, capital requirements for securitization in 2018, and the Standardised Approach for measuring counterparty credit risk (SA-CCR) in 2019.

To comply with the amended regulation relating to risk-weighted assets under Basel III, the Bank completed the consultation and the development of the relevant systems and the amended regulation has been applied since the calculation of the BIS ratio at the end of 2020.

The Bank has completed IT consulting and system development related to Market Risk Regulation (Fundamental Review of the Trading Book , FRTB) and Operational Risk Regulation under Basel III during the second half of 2022.

(viii) Internal capital adequacy assessment process

Internal capital adequacy assessment process is defined as the process that the Bank aggregates significant risks, calculates its internal capital, compares the internal capital with the available capital and assesses its internal capital adequacy. The internal capital adequacy report including the assessment results at the end of the year is prepared and reported to the Risk Management Policy Committee.

• Internal capital adequacy assessment

For the internal capital adequacy assessment, the Bank calculates its aggregated internal capital by evaluating all significant risks and available capital considering the quality and components of capital, and then assesses the internal capital adequacy by comparing the aggregated internal capital with the available capital.

In addition, the Bank conducts periodic stress tests more than once every six months to assess potential weakness in crisis situations and uses its results to assess the internal capital adequacy. The Bank assumes the macroeconomic situation as three stages of ‘normal- pessimistic-serious’ and is preparing countermeasures such as checking the adequacy of capital by each stage.

• Goal setting of internal capital management

The Bank sets up and manages an internal capital limit on an annual basis, through the approval of the Risk Management Committee, to maintain internal capital adequacy by managing internal capital (integrated risks) within the extent of available capital.

The prior year’s internal capital, analysis of domestic and foreign environment changes in the current year, and the direction and size of operations are all reflected in the goal setting of internal capital management to calculate the integrated internal capital scale. Moreover, Bank for International Settlements(BIS) capital adequacy ratio and risk appetite are taken into consideration in the goal setting of internal capital management.

• Allocation of internal capital

The Bank’s Risk Management Committee approves entire internal capital and the Risk Management Policy Committee allocates the capital to each segment and department, considering the extent of possible risk faced and size of operations. The allocated internal capital is monitored regularly and

48. Risk Management, Continued

managed using various management methods. The results of monitoring and managing the allocated internal capital are reported to the Risk Management Committee. In case of any material changes in the Bank’s business plan or risk operation strategy, the Bank adjusts the allocations elastically.

• Composition of internal capital

Internal capital comprises all the significant risks of the Bank and is composed of quantifiable and non-quantifiable risks. Quantifiable risks are composed of credit risk, market risk, interest rate risk, operational risk and credit concentration risk, foreign currency settlement risk, and are risks measured quantitatively by applying reasonable methodology using objective data. Non-quantifiable risks are composed of strategy risk, reputation risk, residual risk on asset securitization and furthermore. Non-quantifiable risks are those risks that cannot be measured quantitatively because of lack of data or the absence of appropriate measuring methodologies.

(2) Credit Risk

(i) Concept

Credit risk can be defined as potential loss resulting from the refusal to perform obligations or default of counterparties. More generally, it is used to refer to the possibility of loss from engaged bonds that cannot be redeemed properly or from substitute payments.

(ii) Approach to credit risk management

Summary of credit risk management

The Bank regards credit risk as the most significant risk area in its business operations, and accordingly, closely monitors its credit risk exposure. The Bank manages both credit risks at portfolio level and at individual credit level. At portfolio level, the Bank reduces credit concentration and restructures the portfolio in such a way to maximize profitability considering the risk level. To avoid credit concentration on a particular sector, the Bank manages credit limits by client, group, and industry. The Bank also resets exposure management directives for each industry by conducting an industry credit evaluation twice a year.

At the individual credit level, the relationship manager (RM), the credit officer (CO) and the Credit Review Committee manage each borrowers’ credit risk.

Post management and insolvent borrower management

The Bank monitors the borrower’s credit rating from the date of the loan to the date of the final collection of debt consistently and inspects the borrower’s status regularly and frequently to prevent the generation of new bad debts and to stabilize the number of debt recoveries.

In addition, an early warning system is operated to spot borrowers that are highly likely to be insolvent. The early warning system provides financial information, financial transaction information, public information and market information of the borrower, and such information is used by the RM and the CO to monitor and manage changes in the borrower’s credit rating.

48. Risk Management, Continued

A borrower that is likely to be insolvent is classified as an early warning borrower or a precautionary borrower, depending on the level of insolvency risk. The Bank sets up a specific and applicable stabilization plan for such a borrower considering the borrower’s characteristics. Furthermore, sub-standard borrowers are classified as insolvent borrowers, and are managed intensively by the Bank, which takes legal proceedings, disposals or corporate turnaround measures if necessary.

Classification of asset soundness and provision of allowance for loss

Classification of asset soundness is fulfilled by the analysis and assessment of credit risk. The classification is used to provide an appropriate allowance, prevent further occurrences of insolvent assets and promote the normalization of existing insolvent assets to enhance the stabilization of asset operations.

Based on the Financial Supervisory Regulations of the Republic of Korea, the Bank has established standards and guidelines on the classification of asset soundness, according to the Forward-Looking Criteria, which reflects not only the borrower’s past records of repayment but also their future debt repayment capability.

In conformity with these standards, the Bank classifies the soundness of its assets as “normal”, “precautionary”, “substandard”, “doubtful”, or “estimated loss” and differentiates the coverage ratio by the level of classification.

Details of loans by credit rating as of June 30, 2024 and December 31, 2023 are as follows:

(iii) Measurement methodology of credit risk

Pursuant to Basel III, the Bank selects the measurement methodology of credit risk considering the complexity of measurement, measurement factors, estimating methods and others. Measurement approaches are divided into Standardized Approach and Internal Ratings-Based Approach.

Standardized Approach (“SA”)

In the case of the Standardized Approach, the risk weights are applied according to the credit rating assessed by External Credit Assessment Institution (“ECAI”). Risk weights in each credit rating are as follows:

Credit rating	Corporate	Country	Bank
AAA ~ AA-	20.0%	0.0%	20.0%
A+ ~ A-	50.0%	20.0%	30.0%
BBB+ ~ BBB-	75.0%	50.0%	50.0%
BB+ ~ BB-	100.0%	100.0%	100.0%
B+ ~ B-	150.0%	100.0%	100.0%
Below B-	150.0%	150.0%	150.0%
Unrated	100.0% (*)	100.0%	Rating based on due diligence

(*) In case of small and medium-sized business, 85.0% is applied.

The OECD is designated as foreign ECAI and Korea Investrors Service Co., Ltd., NICE Investors Services Co., Ltd. and the Korea Ratings Co., Ltd. are designated as domestic ECAI.

The Bank applies the credit rating based on the corresponding loan and same borrower’s unsecured senior loans. In the case the borrower’s risk weight is higher than the unrated exposure’s risk weight (100%), the higher weight is applied. In the case the borrower has more than one rating, the higher weight of the two lowest weights (Second Best Criteria) is applied.

Internal Ratings-Based Approach (IRB)

To use the Internal Ratings-Based Approach, a bank must be approved by the FSS and should also meet the requirement pre-set by the FSS.

In relation to Basel II that has been adopted domestically as of January 2008, the Bank gained approval from the FSS to use the Foundation Internal Ratings-Based Approach in July 2008. The Bank has calculated credit risk-weighted assets using the approach since late June 2008.

Measurement method of credit risk-weighted asset

The Bank calculates credit risk-weighted assets of corporate exposures and asset securitization exposures using the Foundation Internal Ratings-Based Approach as of June 30, 2024.

48. Risk Management, Continued

The Standardized Approach is applied to country exposures, public institution exposures and bank exposures permanently and applied to overseas subsidiary and the Bank’s branch pursuant to prior consultation with the FSS.

<Approved measurement method>
Measurement method		Exposure
Standardized Approach	Permanent SA	— Countries, public institutions, banks, equity
	SA	— Overseas subsidiaries and branches, and other assets, retail, residential mortgage, commercial properties
Foundation Internal Ratings-Based Approach		— Corporate, small and medium enterprises, asset securitization (at each credit level)
Application of IRB by phase		— Special lending, non-residence and others

The mitigated effect of credit risks reflects the related policies which consider eligible collateral and guarantees. The Bank calculates the credit risk-weighted assets using the capital adequacy ratio.

Upon the calculation of credit risk-weighted assets for derivatives, the Bank takes into consideration the set-off effects of transactions under legally enforceable rights to set-off to calculate exposures.

Credit rating model

The results of credit rating are presented as grades through an assessment of the debt repayment capacity that the principal and interest of debt securities or loans are redeemed while complying with contractual redemption schedule.

Using the Bank’s internal credit rating model, the Bank classifies debtors’ credit rating into 14 grades (AAA~D). To distinguish the difference between credits in the same grade, the Bank uses 20 stages as auxiliaries to 14 grades.

The Bank’s regular credit rating process is carried out once a year and in the case of the change of debtor’s credit condition, the credit rating is frequently adjusted as necessary to retain the adequacy of credit rating.

The results of credit rating are applied to various areas such as discrimination of loan processes, loan limit, loan interest rate, post loan management standard process, credit risk measurement, and allowance for loan losses assessment.

Credit rating process control structure

According to the Principle of Checks and Balances, the Bank has established the credit rating process control structure by which the credit rating system operates appropriately.

• Independent assessment of credit rating: The Bank’s business segment (RM) and credit rating assessment segment (Senior Rating Officer) are independently operated.

• Independent control of credit rating system: The control of credit rating system including the development of credit rating model is independently implemented by the Bank’s Risk Management Department.

• Independent verification of credit rating system: Credit rating system is independently verified by Risk Validation Team of the Financial Planning Department.

• Internal audit of credit rating process: Credit rating process is regularly audited by the Bank’s internal audit department.

• Role of the Board of Directors and the Bank’s management: Major issues relating to credit process are approved by the Board of Directors and are regularly monitored by the Bank’s top management.

The Bank reviews debt repayability based on a credit analysis when handling loans. Depending on the results, credit loan preservation is executed as necessary using such methods as interest rate preservation due to credit risk.

The Bank evaluates the value of the collateral, performing ability and legal validity of the guarantee at the initial acquisition. The Bank re-evaluates the provided collateral and guarantees regularly for them to be reasonably preserved.

For guarantees, the Bank demands a corresponding written guarantee according to loan handling standards and the guarantor’s credit rating is independently calculated when in conformance with the credit rating endowment method.

The quantification of the extent to which collateral and other credit enhancements mitigate credit risk of impaired financial assets as of June 30, 2024 and December 31, 2023 are as follows:

	June 30, 2024		December 31, 2023

The equity capital ratio and equity capital according to the standards of the Bank for International Settlements are calculated for such disclosure. The equity capital ratio and equity capital are calculated on a consolidated basis. In conformity with the Banking Act, which is based on the implementation of Basel III on December 1, 2013, the regulatory capital is divided into the following two categories.

Tier 1 capital

- Common Equity Tier 1

Regulatory capital that represents the most subordinated claim in liquidation of the Bank, takes the first and proportionately greatest share of any losses as they occur, and which principal is never repaid outside of liquidation meets the criteria for classification as common equity, including capital stock, capital surplus, retained earnings and accumulated other comprehensive income as common equity Tier 1.

- Additional Tier 1 capital

Capital stock and capital surplus related to issuance of capital securities that are subordinated, have non-cumulative and conditional dividends or interests, and have no maturity or step-up conditions.

Tier 2 capital (Supplementary Tier 2 capital)

Regulatory capital that fulfills supplementary capital adequacy requirements, and includes subordinated debt with maturities over 5 years and allowance for loan losses in conformity with external regulatory standards and internal standards.

(4) Market risk

(i) Concept

Market risk is defined as the possibility of potential loss resulting from fluctuations in interest rates, foreign exchange rates and the price of stocks and commodities. Trading position is exposed to risks, such as interest rate, stock price, and foreign exchange rate, etc. Non-trading position is mostly exposed to interest rates. Accordingly, the Bank classifies market risks into those exposed from trading position or those exposed from non-trading position.

(ii) Market risks of trading positions

Management method on market risks arising from trading positions

In response to the full implementation of Basel III market risk regulations, the Bank has been calculating and managing market risk capital in accordance with the Standardized Approach under Basel III since January 2023. The Standardized Approach under Basel III measures market risk by three components: sensitivity risk, default risk and residual risk. Sensitivity risk measures the market risk by five risk classes, which are general interest rate, credit spread, equity, foreign exchange and commodity. Default risk quantifies losses in the event of a default that exceeds normal market price fluctuations. Lastly, residual risk quantifies risk that cannot be measured by sensitivity risk and default risk. These components are then simply added together to calculate the total required capital.

The Bank sets total limit of market risk based on annual business plan, risk appetite and others and monitors Market Risk limit of each trading department on a daily basis.

Capital Requirements for Market risk

The Bank’s Capital Requirements for Market risk as of June 30, 2024 and December 31, 2023 are as follows:

	June 30, 2024		December 31, 2023
Sensitivity risk:
General interest rate	W	99,817		112,612
Credit spread		105,582		84,971
Equity		726		815
Foreign exchange (FX)		6,542		8,383
Commodity		558		120
		213,225		206,901
Default risk		4,266		7,696
Residual risk		4,773		3,901

(iii) Market risks of non-trading positions

Management method on market risks arising from non-trading positions

The most critical market risk that arises in non-trading position is the interest rate risk. Interest rate risk is defined as the likely loss resulting from the unfavorable fluctuation of interest rate in the Bank’s financial condition and is measured by IRRBB (Interest Rate Risk in Banking Book), ΔEVE (change in Economic Value of Equity) and ΔNII (change in Net Interest Income).

ΔEVE represents fluctuations in the economic value of equity capital that may occur due to changes in interest rates affecting the present values of assets, liabilities and off-balance sheet items. ΔNII represents changes in net interest income that may occur over a certain period of time (e.g. one year) in the future due to changes in interest rates.

The Bank’s Risk Management Committee sets and manages interest rate risk limits on a yearly basis and interest rate risk is monthly measured and monitored.

ΔEVE and ΔNII of the Bank’s non-trading positions as of June 30, 2024 and December 31, 2023 are as follows:

	June 30, 2024		December 31, 2023
ΔEVE	W	1,405,114		1,920,912
ΔNII		479,416		583,853

(v) Interest rate risk management

The Bank is closely monitoring the outputs prepared by the industrial working groups which is managing the transition to alternative benchmark rates and the markets related the rates. The outputs include the information published by regulatory authorities related to IBORs. The authorities have made it clear that after the end of 2021, they will no longer persuade or force banks to submit IBORs. Responding the transition, the Bank organized a task force led by the head of the risk management division and the task force has established the LIBOR transition plan that consists of work flows such as alternative interest rate determination, application development, customer communication management, risk management, taxation, finance, legal, and accounting system establishment. The important progress of the plan is reported to the management and may also be reported to the board of directors if necessary. The purpose of the task force is to review where exposure to IBOR occurs within the Bank’s business, and to develop and implement the plan to transit to the alternative benchmark rates. As of June 30, 2024, we have finalized the introduction of conversion and replacement rates for the majority of our U.S. dollar-denominated contracts. However, we aim to complete the conversion of certain unconverted contracts with maturities after June 2024 by the first interest rate rebalancing date that occurs.

(5) Liquidity risk management

(i) Concept

Liquidity risk is defined as the possibility of potential loss due to a temporary shortage in funds caused by a maturity mismatch or an unexpected capital outlay. Liquidity risk soars when funding rates rise, assets are sold below a normal price, or a good investment opportunity is missed.

(ii) Approach to liquidity risk management

The Bank manages its liquidity risks as follows:

Allowable limit for liquidity risk

• The allowable limit for liquidity risk sets LCR, NSFR and Mid- to long-term foreign currency fund management ratio

• The management standards with regards to the allowable limit for liquidity risk should be set using separate and stringent set ratios in accordance with the FSS guidelines.

<Measurement Methodology>

• LCR: (High quality liquid assets / Total net cash outflows over the next 30 calendar days) X 100

• NSFR: Available Stable Funding / Required Stable Funding X 100

• Mid- to long-term foreign currency fund management ratio: Foreign currency funding being repaid after 1 year / Foreign currency lending being collected after 1 year X 100

Early warning indicator

To identify prematurely and cope with worsening liquidity risk trends, the Bank has set up 15 indexes such as the “Foreign Exchange Stabilization Bond CDS Premium,” and measures the trend monthly as a means for establishing the allowable liquidity risk limit complementary measures.

Stress-Test analysis and contingency plan

• The Bank evaluates the effects on the liquidity risk and identifies the inherent flaws. In the case where an unpredictable and significant liquidity crisis occurs, the Bank executes risk situation analysis quarterly based on crisis specific to the Bank, market risk and complex emergency, and reports to the Risk Management Committee for the Bank’s solvency securitization.

• The Bank established detailed contingency plan to manage the liquidity risks at every risk situations.

THE REPUBLIC OF KOREA

The Economy

Gross Domestic Product

Based on preliminary data, GDP growth in the first half of 2024 was 2.3% at chained 2020 year prices, primarily due to an 8.7% increase in exports of goods and services and a 1.3% increase in aggregate private and general government consumption expenditures, the effects of which were offset in part by a 2.7% increase in imports of goods and services and a 0.7% decrease in gross domestic fixed capital formation, each compared with the corresponding period of 2023.

Principal Sectors of the Economy

Prices, Wages and Employment

Based on preliminary data, the inflation rate was 2.7% and the unemployment rate was 2.9% in the first half of 2024.

The Financial System

Securities Markets

The Korea Composite Stock Price Index was 2,797.82 on June 28, 2024, 2,770.69 on July 31, 2024, 2,674.31 on August 30, 2024, 2,593.27 on September 30, 2024 and 2,569.71 on October 4, 2024.

Monetary Policy

Foreign Exchange

The market average exchange rate between the Won and the U.S. Dollar (in Won per one U.S. Dollar) as announced by the Seoul Money Brokerage Service Ltd. was Won 1,389.2 to US$1.00 on June 28, 2024, Won 1,384.6 to US$1.00 on July 31, 2024, Won 1,335.3 to US$1.00 on August 30, 2024, Won 1,319.6 to US$1.00 on September 30, 2024 and Won 1,320.1 to US$1.00 on October 4, 2024.

Balance of Payments and Foreign Trade

Balance of Payments

Based on preliminary data, the Republic’s current account surplus in the first half of 2024 increased to US$37.7 billion from the current account surplus of US$1.2 billion in the corresponding period of 2023, primarily due to a change from a deficit to a surplus from the goods account and a decrease in deficit from the services account, the effects of which were offset in part by a decrease in surplus from the income account.

Trade Balance

Based on preliminary data, the Republic recorded a trade surplus of US$23.1 billion in the first half of 2024. Exports increased by 9.0% to US$334.8 billion in the first half of 2024 from US$307.0 billion in the corresponding period of 2023, primarily due to an improvement in the domestic economic conditions of the Republic’s major trading partners. Imports decreased by 6.5% to US$311.7 billion in the first half of 2024 from US$333.3 billion in the corresponding period of 2023, primarily due to a decrease in energy and commodity prices, which also led to decreased unit prices of other major raw materials.

Foreign Currency Reserves

The amount of the Government’s foreign currency reserves was US$415.9 billion as of August 31, 2024.

DESCRIPTION OF THE NOTES

The following is a description of some of the terms of the Notes we are offering. Since it is only a summary, we urge you to read the fiscal agency agreement described below and the forms of global note before deciding whether to invest in the Notes. We have filed a copy of these documents with the United States Securities and Exchange Commission as exhibits to the registration statement no. 333-280021.

The general terms of our Notes are described in the accompanying prospectus. The description in this prospectus supplement further adds to that description or, to the extent inconsistent with that description, replaces it.

The Notes

We are offering US$1,000,000,000 aggregate principal amount of 4.125% notes due October 16, 2027 (the “Notes”).

Governed by Fiscal Agency Agreement

We will issue the Notes under the fiscal agency agreement, dated as of February 15, 1991, as amended and supplemented from time to time, between us and The Bank of New York (now The Bank of New York Mellon), as fiscal agent (the “Fiscal Agency Agreement”). The fiscal agent will maintain a register for the Notes.

Payment of Principal and Interest

The Notes are initially limited to US$1,000,000,000 aggregate principal amount. The Notes will mature on October 16, 2027 (the “Maturity Date”). The Notes will bear interest at the rate of 4.125% per annum, payable semi-annually in arrear on April 16 and October 16 of each year (each, an “Interest Payment Date”), beginning on April 16, 2025. Interest on the Notes will accrue from October 16, 2024. If any Interest Payment Date or the Maturity Date shall be a day on which banking institutions in The City of New York or Seoul are authorized or obligated by law to close, then such payment will not be made on such date but will be made on the next succeeding day which is not a day on which banking institutions in The City of New York or Seoul are authorized or obligated by law to close, with the same force and effect as if made on the date for such payment, and no interest shall be payable in respect of any such delay. We will pay interest to the person who is registered as the owner of a Note at the close of business on the fifteenth day (whether or not a business day) preceding the related Interest Payment Date. Interest on the Notes will be computed on the basis of a 360-day year consisting of twelve 30-day months. We will make principal and interest payments on the Notes in immediately available funds in U.S. dollars.

Denomination

The Notes will be issued in minimum denominations of US$200,000 principal amount and integral multiples of US$1,000 in excess thereof.

Redemption

We may not redeem the Notes prior to maturity. At maturity, we will redeem the Notes at par.

Form and Registration

We will issue each series of the Notes in the form of one or more fully registered global notes, registered in the name of a nominee of and deposited with the custodian for DTC. Except as described in the accompanying prospectus under “Description of the Securities—Description of Debt Securities—Global Securities,” the global

S-147

notes will not be exchangeable for Notes in definitive registered form, and will not be issued in definitive registered form. Financial institutions, acting as direct and indirect participants in DTC, will represent your beneficial interests in the global notes. These financial institutions will record the ownership and transfer of your beneficial interest through book-entry accounts. You may hold your beneficial interests in the Notes through Euroclear or Clearstream if you are a participant in such systems, or indirectly through organizations that are participants in such systems. Any secondary market trading of book-entry interests in the Notes will take place through DTC participants, including Euroclear and Clearstream. See “Clearance and Settlement—Transfers Within and Between DTC, Euroclear and Clearstream.”

General

The fiscal agent will not charge you any fees for the Notes, other than reasonable fees for the replacement of lost, stolen, mutilated or destroyed Notes. However, you may incur fees for the maintenance and operation of the book-entry accounts with the clearing systems in which your beneficial interests are held.

For so long as the Notes are listed on the SGX-ST and the rules of the SGX-ST so require, in the event that any of the global notes are exchanged for Notes in definitive registered form, we will appoint and maintain a paying agent in Singapore, where the certificates representing the Notes may be presented or surrendered for payment or redemption. In addition, in the event that any of the global notes are exchanged for Notes in definitive registered form, an announcement of such exchange will be made through the SGX-ST by or on behalf of us. Such announcement will include all material information with respect to the delivery of the certificates representing the Notes, including details of the paying agent in Singapore.

Further Issues

We may from time to time, without the consent of the holders of the Notes, create and issue additional debt securities with the same terms and conditions as either series of the Notes in all respects so that such further issue shall be consolidated and form a single series with the relevant series of the Notes. We will not issue any such additional debt securities unless such additional securities have less than a de minimis amount of original issue discount or such issuance would otherwise constitute a “qualified reopening” for U.S. federal income tax purposes.

Notices

All notices regarding the Notes will be published by us in London in the Financial Times and in New York in The Wall Street Journal (U.S. Edition). If we cannot, for any reason, publish notice in any of those newspapers, we will choose an appropriate alternate English language newspaper of general circulation, and notice in that newspaper will be considered valid notice. Notice will be considered made on the first date of its publication.

S-148

CLEARANCE AND SETTLEMENT

We have obtained the information in this section from sources we believe to be reliable, including DTC, Euroclear and Clearstream. We accept responsibility only for accurately extracting information from such sources. DTC, Euroclear and Clearstream are under no obligation to perform or continue to perform the procedures described below, and they may modify or discontinue them at any time. Neither we nor the registrar will be responsible for DTC’s, Euroclear’s or Clearstream’s performance of their obligations under their rules and procedures. Nor will we or the registrar be responsible for the performance by direct or indirect participants of their obligations under their rules and procedures.

Introduction

The Depository Trust Company

DTC is:

• a limited-purpose trust company organized under the New York Banking Law;

• a “banking organization” under the New York Banking Law;

• a member of the Federal Reserve System;

• a “clearing corporation” under the New York Uniform Commercial Code; and

• a “clearing agency” registered under Section 17A of the Securities Exchange Act of 1934.

DTC was created to hold securities for its participants and facilitate the clearance and settlement of securities transactions between its participants. It does this through electronic book-entry changes in the accounts of its direct participants, eliminating the need for physical movement of securities certificates.

Euroclear and Clearstream

Like DTC, Euroclear and Clearstream hold securities for their participants and facilitate the clearance and settlement of securities transactions between their participants through electronic book-entry changes in their accounts. Euroclear and Clearstream provide various services to their participants, including the safekeeping, administration, clearance and settlement and lending and borrowing of internationally traded securities. Participants in Euroclear and Clearstream are financial institutions such as underwriters, securities brokers and dealers, banks and trust companies. Some of the underwriters participating in this offering are participants in Euroclear or Clearstream. Other banks, brokers, dealers and trust companies have indirect access to Euroclear or Clearstream by clearing through or maintaining a custodial relationship with a Euroclear or Clearstream participant.

Ownership of the Notes through DTC, Euroclear and Clearstream

We will issue the Notes in the form of one or more fully registered global notes, registered in the name of a nominee of DTC. Financial institutions, acting as direct and indirect participants in DTC, will represent your beneficial interests in the global notes. These financial institutions will record the ownership and transfer of your beneficial interests through book-entry accounts. You may hold your beneficial interests in the global notes through Euroclear or Clearstream, if you are a DTC participant in such systems, or indirectly through organizations that are DTC participants in such systems. Euroclear and Clearstream will hold their Euroclear/Clearstream participants’ beneficial interests in the global notes in their customers’ securities accounts with their depositaries. These depositaries of Euroclear and Clearstream in turn will hold such interests in their customers’ securities accounts with DTC.

We and the fiscal agent generally will treat the registered holder of the Notes, initially Cede & Co., as the absolute owner of the Notes for all purposes. Once we and the fiscal agent make payments to the registered holder, we and the fiscal agent will no longer be liable on the Notes for the amounts so paid. Accordingly, if you

S-149

own a beneficial interest in the global notes, you must rely on the procedures of the institutions through which you hold your interests in the Notes, including DTC, Euroclear, Clearstream and their respective participants, to exercise any of the rights granted to holders of Notes. Under existing industry practice, if you desire to take any action that Cede & Co., as the holder of the global notes, is entitled to take, then Cede & Co. would authorize the DTC participant through which you own your beneficial interest to take such action. The DTC participant would then either authorize you to take the action or act for you on your instructions.

DTC may grant proxies or authorize its DTC participants, or persons holding beneficial interests in the Notes through such DTC participants, to exercise any rights of a holder or take any actions that a holder is entitled to take under the Fiscal Agency Agreement or the Notes. Euroclear’s or Clearstream’s ability to take actions as holder under the Notes or the Fiscal Agency Agreement will be limited by the ability of their respective depositaries to carry out such actions for them through DTC. Euroclear and Clearstream will take such actions only in accordance with their respective rules and procedures.

The fiscal agent will not charge you any fees for the Notes, other than reasonable fees and indemnity satisfactory to the fiscal agent for the replacement of lost, stolen, mutilated or destroyed Notes. However, you may incur fees for the maintenance and operation of the book-entry accounts with the clearing systems in which your beneficial interests are held.

Transfers Within and Between DTC, Euroclear and Clearstream

Trading Between DTC Purchasers and Sellers

DTC participants will transfer interests in the Notes among themselves in the ordinary way according to DTC rules. Participants will pay for such transfers by wire transfer. The laws of some states require certain purchasers of securities to take physical delivery of the securities in definitive form. These laws may impair your ability to transfer beneficial interests in the global notes to such purchasers. DTC can act only on behalf of its direct participants, who in turn act on behalf of indirect participants and certain banks. Thus, your ability to pledge a beneficial interest in the global notes to persons that do not participate in the DTC system, and to take other actions, may be limited because you will not possess a physical certificate that represents your interest.

Trading Between Euroclear and/or Clearstream Participants

Participants in Euroclear and Clearstream will transfer interests in the Notes among themselves according to the rules and operating procedures of Euroclear and Clearstream.

Trading Between a DTC Seller and a Euroclear or Clearstream Purchaser

When the Notes are to be transferred from the account of a DTC participant to the account of a Euroclear or Clearstream participant, the purchaser must first send instructions to Euroclear or Clearstream through a participant at least one business day prior to the settlement date. Euroclear or Clearstream will then instruct its depositary to receive the Notes and make payment for them. On the settlement date, the depositary will make payment to the DTC participant’s account, and the Notes will be credited to the depositary’s account. After settlement has been completed, DTC will credit the Notes to Euroclear or Clearstream, Euroclear or Clearstream will credit the Notes, in accordance with its usual procedures, to the participant’s account, and the participant will then credit the purchaser’s account. These securities credits will appear the next day (European time) after the settlement date. The cash debit from the account of Euroclear or Clearstream will be back-valued to the value date, which will be the preceding day if settlement occurs in New York. If settlement is not completed on the intended value date (i.e., the trade fails), the cash debit will instead be valued at the actual settlement date.

Participants in Euroclear and Clearstream will need to make funds available to Euroclear or Clearstream to pay for the Notes by wire transfer on the value date. The most direct way of doing this is to pre-position funds (i.e., have funds in place at Euroclear or Clearstream before the value date), either from cash on hand or existing

S-150

lines of credit. Under this approach, however, participants may take on credit exposure to Euroclear and Clearstream until the Notes are credited to their accounts one day later.

As an alternative, if Euroclear or Clearstream has extended a line of credit to a participant, the participant may decide not to pre-position funds, but to allow Euroclear or Clearstream to draw on the line of credit to finance settlement for the Notes. Under this procedure, Euroclear or Clearstream would charge the participant overdraft charges for one day, assuming that the overdraft would be cleared when the Notes were credited to the participant’s account. However, interest on the Notes would accrue from the value date. Therefore, in many cases the interest income on the Notes which the participant earns during that one-day period will substantially reduce or offset the amount of the participant’s overdraft charges. Of course, this result will depend on the cost of funds (i.e., the interest rate that Euroclear or Clearstream charges) to each participant.

Since the settlement will occur during New York business hours, a DTC participant selling an interest in the Notes can use its usual procedures for transferring global securities to the depositories of Euroclear or Clearstream for the benefit of Euroclear or Clearstream participants. The DTC seller will receive the sale proceeds on the settlement date. Thus, to the DTC seller, a cross-market sale will settle no differently than a trade between two DTC participants.

Finally, day traders who use Euroclear or Clearstream and who purchase Notes from DTC participants for credit to Euroclear participants or Clearstream participants should note that these trades will automatically fail unless one of three steps is taken:

• borrowing through Euroclear or Clearstream for one day, until the purchase side of the day trade is reflected in the day trader’s Euroclear or Clearstream account, in accordance with the clearing system’s customary procedures;

• borrowing the Notes in the United States from DTC participants no later than one day prior to settlement, which would allow sufficient time for the Notes to be reflected in the Euroclear or Clearstream account in order to settle the sale side of the trade; or

• staggering the value dates for the buy and sell sides of the trade so that the value date for the purchase from the DTC participant is at least one day prior to the value date for the sale to the Euroclear or Clearstream participant.

Trading Between a Euroclear or Clearstream Seller and a DTC Purchaser

Due to time-zone differences in their favor, Euroclear and Clearstream participants can use their usual procedures to transfer Notes through their depositaries to a DTC participant. The seller must first send instructions to Euroclear or Clearstream through a participant at least one business day prior to the settlement date. Euroclear or Clearstream will then instruct its depositary to credit the Notes to the DTC participant’s account and receive payment. The payment will be credited in the account of the Euroclear or Clearstream participant on the following day, but the receipt of the cash proceeds will be back-valued to the value date, which will be the preceding day if settlement occurs in New York. If settlement is not completed on the intended value date (i.e., the trade fails), the receipt of the cash proceeds will instead be valued at the actual settlement date.

If the Euroclear or Clearstream participant selling the Notes has a line of credit with Euroclear or Clearstream and elects to be in debit for the Notes until it receives the sale proceeds in its account, then the back-valuation may substantially reduce or offset any overdraft charges that the participant incurs over that period.

Settlement in other currencies between DTC and Euroclear and Clearstream is possible using free-of-payment transfers to move the Notes, but funds movement will take place separately.

UNDERWRITING

Relationship with the Underwriters

We and the underwriters named below (the “Underwriters”) have entered into a Terms Agreement dated October 8, 2024 (the “Terms Agreement”) with respect to the Notes relating to the Underwriting Agreement—Standard Terms (together with the Terms Agreement, the “Underwriting Agreement”) filed as an exhibit to the registration statement. Subject to the terms and conditions set forth in the Underwriting Agreement, we have agreed to sell to each of the Underwriters, severally and not jointly, and each of the Underwriters has, severally and not jointly, agreed to purchase, the following principal amount of the Notes set out opposite its name below:

Names of the Underwriters	Principal Amount of the Notes
BNP Paribas		US$200,000,000
J.P. Morgan Securities plc		200,000,000
KDB Asia Limited		200,000,000
Nomura Singapore Limited		200,000,000
UBS AG Hong Kong Branch		200,000,000
Total		US$1,000,000,000

KDB Asia Limited, one of the underwriters, is our affiliate and has agreed to offer and sell the Notes only outside the United States to non-U.S. persons.

Under the terms and conditions of the Underwriting Agreement, if the Underwriters take any series of the Notes, then the Underwriters are obligated to take and pay for all of the Notes of such series.

The Underwriters initially propose to offer the Notes directly to the public at the offering price described on the cover page of this prospectus supplement. After the initial offering of the Notes, the Underwriters may from time to time vary the offering price and other selling terms.

If a jurisdiction requires that the offering be made by a licensed broker or dealer and the Underwriters or any affiliate of the Underwriters is a licensed broker or dealer in that jurisdiction, the offering shall be deemed to be made by that Underwriter or its affiliate on our behalf in such jurisdiction.

The Notes are a new class of securities with no established trading market. Application will be made to the SGX-ST for the listing and quotation of the Notes on the SGX-ST. In addition, application will be made to list the Notes on the Luxembourg Stock Exchange and to have the Notes admitted to trading on the Euro MTF Market of the Luxembourg Stock Exchange. Application will also be made for listing of the Notes to the International Securities Market of the London Stock Exchange. No assurance can be given that such applications will be approved or that such listings will be maintained. The Underwriters have advised us that they intend to make a market in the Notes. However, they are not obligated to do so and they may discontinue any market making activities with respect to the Notes at any time without notice. Accordingly, we cannot assure you as to the liquidity of any trading market for the Notes.

We have agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments which the Underwriters may be required to make in respect of any such liabilities.

The amount of our net proceeds from the Notes is US$994,570,000 after deducting underwriting discounts but not estimated expenses. Expenses associated with the Notes offering are estimated to be US$100,000. The Underwriters have agreed to pay certain of our expenses incurred in connection with the offering of the Notes.

S-153

The Underwriters and certain of their affiliates may have performed certain commercial banking, investment banking and advisory services for us and/or our affiliates from time to time for which they have received customary fees and expenses and may, from time to time, engage in transactions with and perform services for us and/or our affiliates in the ordinary course of their business.

The Underwriters or certain of their affiliates may purchase Notes and be allocated Notes for asset management and/or proprietary purposes but not with a view to distribution. The Underwriters or their respective affiliates may purchase Notes for their own account and enter into transactions, including credit derivatives, such as asset swaps, repackaging and credit default swaps relating to Notes and/or other securities of us or our subsidiaries or affiliates at the same time as the offer and sale of Notes or in secondary market transactions. Such transactions would be carried out as bilateral trades with selected counterparties and separately from any existing sale or resale of Notes to which this prospectus supplement relates (notwithstanding that such selected counterparties may also be purchasers of Notes).

Important Notice to CMIs (including private banks)

This notice to CMIs (including private banks) is a summary of certain obligations the SFC Code imposes on CMIs, which require the attention and cooperation of other CMIs (including private banks). Certain CMIs may also be acting as OCs for this offering and are subject to additional requirements under the SFC Code.

Prospective investors who are the directors, employees or major shareholders of the Issuer, a CMI or its group companies would be considered under the SFC Code as having an Association with the Issuer, the CMI or the relevant group company. CMIs should specifically disclose whether their investor clients have any Association when submitting orders for the Notes. In addition, private banks should take all reasonable steps to identify whether their investor clients may have any Associations with the Issuer or any CMI (including its group companies) and inform the Underwriters accordingly.

CMIs are informed that the marketing and investor targeting strategy for this offering includes institutional investors, sovereign wealth funds, pension funds, hedge funds, family offices and high net worth individuals, in each case, subject to the selling restrictions set out elsewhere in this prospectus supplement.

CMIs should ensure that orders placed are bona fide, are not inflated and do not constitute duplicated orders (i.e., two or more corresponding or identical orders placed via two or more CMIs). CMIs should enquire with their investor clients regarding any orders which appear unusual or irregular. CMIs should disclose the identities of all investors when submitting orders for the Notes (except for omnibus orders where underlying investor information may need to be provided to any OCs when submitting orders). Failure to provide underlying investor information for omnibus orders, where required to do so, may result in that order being rejected. CMIs should not place “X-orders” into the order book.

CMIs should segregate and clearly identify their own proprietary orders (and those of their group companies, including private banks as the case may be) in the order book and book messages.

CMIs (including private banks) should not offer any rebates to prospective investors or pass on any rebates provided by the Issuer. In addition, CMIs (including private banks) should not enter into arrangements which may result in prospective investors paying different prices for the Notes.

The SFC Code requires that a CMI disclose complete and accurate information in a timely manner on the status of the order book and other relevant information it receives to targeted investors for them to make an informed decision. In order to do this, those Underwriters in control of the order book should consider disclosing order book updates to all CMIs.

S-154

When placing an order for the Notes, private banks should disclose, at the same time, if such order is placed other than on a “principal” basis (whereby it is deploying its own balance sheet for onward selling to investors). private banks who do not provide such disclosure are hereby deemed to be placing their order on such a “principal” basis. Otherwise, such order may be considered to be an omnibus order pursuant to the SFC Code. private banks should be aware that placing an order on a “principal” basis may require the Underwriters to apply the “proprietary orders” of the SFC Code to such order and will require the Underwriters to apply the “rebates” requirements of the SFC Code (if applicable) to such order.

In relation to omnibus orders, when submitting such orders, CMIs (including private banks) that are subject to the SFC Code should disclose underlying investor information in respect of each order constituting the relevant omnibus order (failure to provide such information may result in that order being rejected). Underlying investor information in relation to omnibus orders should consist of:

• The name of each underlying investor;

• A unique identification number for each investor;

• Whether an underlying investor has any “Associations” (as used in the SFC Code);

• Whether any underlying investor order is a “Proprietary Order” (as used in the SFC Code);

• Whether any underlying investor order is a duplicate order.

Underlying investor information in relation to omnibus orders should be sent to: dl.asia.syndicate@asia.bnpparibas.com; Investor.info.hk.bond.deals@jpmorgan.com; kdb_syndicate@kdb.co.kr; ol-ubs-dcm-hk-syndicate@ubs.com.

To the extent information being disclosed by CMIs and investors is personal and/or confidential in nature, CMIs (including private banks) agree and warrant: (A) to take appropriate steps to safeguard the transmission of such information to any OCs; and (B) that they have obtained the necessary consents from the underlying investors to disclose such information to any OCs. By submitting an order and providing such information to any OCs, each CMI (including private banks) further warrants that they and the underlying investors have understood and consented to the collection, disclosure, use and transfer of such information by any OCs and/or any other third parties as may be required by the SFC Code, including to the Issuer, relevant regulators and/or any other third parties as may be required by the SFC Code, for the purpose of complying with the SFC Code, during the bookbuilding process for this offering. CMIs that receive such underlying investor information are reminded that such information should be used only for submitting orders in this offering. The Underwriters may be asked to demonstrate compliance with their obligations under the SFC Code, and may request other CMIs (including private banks) to provide evidence showing compliance with the obligations above (in particular, that the necessary consents have been obtained). In such event, other CMIs (including private banks) are required to provide the Underwriters with such evidence within the timeline requested.

Delivery of the Notes

We expect to make delivery of the Notes, against payment in same-day funds on or about October 16, 2024, which we expect will be the fifth business day following the date of this prospectus supplement. Under Rule 15c6-1 promulgated under the Securities Exchange Act of 1934, as amended, U.S. purchasers are generally required to settle trades in the secondary market in one business day, unless they and the other parties to any such trade expressly agree otherwise. Accordingly, if you wish to trade in the Notes on any day prior to the first business day from the settlement, because the Notes will initially settle in T+5, you may be required to specify an alternate settlement cycle at the time of your trade to prevent a failed settlement. Purchasers in other countries should consult with their own advisors.

Canada

Prospective Canadian investors are advised that the information contained within the prospectus supplement and the accompanying prospectus has not been prepared with regard to matters that may be of particular concern to Canadian investors. Accordingly, prospective Canadian investors should consult with their own legal, financial and tax advisers concerning the information contained within the prospectus supplement and the accompanying prospectus and as to the suitability of an investment in the Notes in their particular circumstances.

Each Underwriter has severally represented and agreed that the Notes may only be offered or sold in the provinces of Alberta, British Columbia, Ontario and Québec or to or for the benefit of a resident of these provinces pursuant to an exemption from the requirement to file a prospectus in such province in which such offer or sale is made, and only by a dealer duly registered under the applicable securities laws of that province or by a dealer that is relying in that province on the “international dealer” exemption provided by section 8.18 of National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations (NI 31-103). Furthermore, the Notes may only be offered or sold to or for the benefit of a resident of any such province provided that such resident is purchasing, or deemed to be purchasing, as principal and is both an “accredited investor” as defined in National Instrument 45-106 Prospectus Exemptions (NI 45-106) or subsection 73.3 (1) of the Securities Act (Ontario) and a “permitted client” as defined in NI 31-103. By purchasing any Notes and accepting delivery of a purchase confirmation a purchaser is representing to the underwriters and the dealer from whom the purchase confirmation is received that it is an “accredited investor” and “permitted client” as defined above. The distribution of the Notes in Canada is being made on a private placement basis only and any resale of the Notes must be made in accordance with applicable Canadian securities laws, which will vary depending on the relevant jurisdiction, and which may require resales to be made in accordance with prospectus and registration requirements or exemptions from the prospectus and registration requirements.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement or the accompanying prospectus (including any amendment hereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Under Canadian securities law, National Instrument 33-105 Underwriting Conflicts (NI 33-105) provides disclosure requirements with respect to potential conflicts of interest between an issuer and underwriters, dealers or placement agents, as the case may be. To the extent any conflict of interest between us and any of the Underwriters (or any other placement agent acting in connection with this offering) may exist in respect of this offering, the applicable parties to this offering are relying on the exemption from these disclosure requirements provided to them by section 3A.3 of NI 33-105 (exemption based on U.S. disclosure).

Upon receipt of this prospectus, each Canadian purchaser hereby confirms that it has expressly requested that all documents evidencing or relating in any way to the sale of the securities described herein (including for greater certainty any purchase confirmation or any notice) be drawn up in the English language only. Par la réception de ce prospectus, chaque acheteur canadien confirme par les présentes qu’il a expressément exigé que tous les documents faisant foi ou se rapportant de quelque manière que ce soit à la vente des valeurs mobilières décrites aux présentes (incluant, pour plus de certitude, toute confirmation d’achat ou tout avis) soient rédigés en anglais seulement.

Price Stabilization and Short Position

In connection with this offering, any of the Underwriters appointed and acting in its capacity as stabilizing manager (the “Stabilizing Manager”) or any person acting for it, on behalf of the Underwriters, may purchase and sell the Notes in the open market. These transactions may include over-allotment, covering transactions, penalty bids and stabilizing transactions. Over-allotment involves sales of the Notes in excess of the principal amount of Notes to be purchased by the Underwriters in this offering, which creates a short position for the Underwriters. Covering transactions involve purchases of the Notes in the open market after the distribution has been completed in order to cover short positions. A penalty bid occurs when a particular Underwriter repays to the Underwriters a portion of the underwriting discount received by it because the Underwriters or the Stabilizing Manager has repurchased Notes sold by or for the account of such Underwriter in stabilizing or short covering transactions. Stabilizing transactions consist of certain bids or purchases of Notes in the open market for the purpose of preventing or retarding a decline in the market price of the Notes while the offering is in progress. Any of these activities may have the effect of preventing or retarding a decline in the market price of the Notes. They may also cause the price of the Notes to be higher than the price that otherwise would exist in the open market in the absence of these transactions. The Stabilizing Manager may conduct these transactions in the over-the-counter market or otherwise. If the Stabilizing Manager commences any of these transactions, it may discontinue them at any time, and must discontinue them after a limited period.
