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$800,000,000 aggregate principal amount of floating rate notes due June 1, 2021 (the “2021 Notes”) and US$700,000,000 aggregate principal amount of floating rate notes due June 1, 2023 (the “2023 Notes”, and together with the 2021 Notes, the “Notes”).

The 2021 Notes will bear interest for each Interest Period (as defined herein) at a rate equal to Three-Month USD LIBOR plus 0.575% per annum, and the 2023 Notes will bear interest for each Interest Period at the rate equal to Three-Month USD LIBOR plus 0.775% per annum, in each case payable quarterly in arrears on March 1, June 1, September 1 and December 1 of each year. The first interest payment on the Notes will be made on September 1, 2018 in respect of the period from (and including) June 1, 2018 to (but excluding) September 1, 2018. Interest on the Notes will accrue from June 1, 2018 and will be computed on the basis of the actual number of days in the applicable Interest Period divided by 360. 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.

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

Listing

Applications 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. There can be no assurance that such listing will be obtained for the Notes. 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.

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. 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 S.A./N.V. (“Euroclear”) or Clearstream Banking,société anonyme(“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 any 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 the issuance would constitute a “qualified reopening” for U.S. federal income tax purposes or such additional debt securities would otherwise be part of the same “issue” for U.S. federal income tax purposes.

Delivery of the Notes

We expect to make delivery of the Notes, against payment insame-day funds on or about June 1, 2018, which we expect will be the sixth business day following the date of this prospectus supplement, referred to as “T+6.” You should note that initial trading of the Notes may be affected by the T+6 settlement. See “Underwriting—Delivery of the Notes.”

For the three months ended March 31, 2018, we had net income of ￦229 billion compared to net income of ￦423 billion for the three months ended March 31, 2017.

The principal factors for the decrease in net income in the first quarter of 2018 compared to the corresponding period of 2017 included:

• a decrease in reversal of provision for acceptances and guarantees to ￦114 billion in the first quarter of 2018 from ￦219 billion in the corresponding period of 2017, primarily due to a decrease in refund guarantees to shipbuilding companies, which resulted in an improvement in guarantee quality;

• an increase in provision for loan losses to ￦86 billion in the first quarter of 2018 from ￦14 billion in the corresponding period of 2017, primarily due to an increase innon-performing loans;

S-10

• a decrease in net interest income to ￦192 billion in the first quarter of 2018 from ￦245 billion in the corresponding period of 2017, primarily due to a decrease in interest income from loans as well as a decrease in interest expense from debentures;

• a decrease in net gain on commission to ￦74 billion in the first quarter of 2018 from ￦113 billion in the corresponding period of 2017, primarily due to a decrease in guarantees; and

• a decrease in dividend income to ￦7 billion in the first quarter of 2018 from ￦33 billion in the corresponding period of 2017, primarily due to a decrease in dividend income from our associates and subsidiaries.

The above factors were partially offset by a decrease in income tax expense to ￦74 billion in the first quarter of 2018 from ￦135 billion in the corresponding period of 2017, primarily due to a decrease in income before income tax to ￦303 billion in the first quarter of 2018 from ￦558 billion in the corresponding period of 2017.

As of March 31, 2018, our total assets increased to ￦84,594 billion from ￦83,946 billion as of December 31, 2017, primarily due to an increase in Loan Credits to ￦73,200 billion as of March 31, 2018 from ￦71,884 billion as of December 31, 2017.

As of March 31, 2018, our total liabilities increased to ￦72,294 billion from ￦71,433 billion as of December 31, 2017. The increase in liabilities was primarily due to an increase in accounts payable to ￦418 billion as of March 31, 2018 from ￦57 billion as of December 31, 2017 and an increase in debentures to ￦60,949 billion as of March 31, 2018 from ￦60,685 billion as of December 31, 2017.

The increase in assets and liabilities was primarily due to the increase in the volume of loans and debt, respectively. The appreciation of the Won against the U.S. dollar as of March 31, 2018 compared to December 31, 2017 partially offset the effect of the increase in the volume of loans and debt, as a majority of our assets and liabilities consisted of foreign currency loans and debt (including significant percentages in U.S. dollars).

As of March 31, 2018, our total shareholders’ equity decreased to ￦12,299 billion from ￦12,513 billion as of December 31, 2017, primarily due to net loss on valuation ofavailable-for-sale securities of ￦48 billion in the first quarter of 2018 compared to net gain on valuation ofavailable-for-sale securities to ￦199 billion as of December 31, 2017.

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 form of global note before deciding whether to invest in the Notes. We have filed a copy of these documents with the U.S. Securities and Exchange Commission as exhibits to the registration statement no.333-217916.

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.

Governed by Fiscal Agency Agreement

We will issue the Notes under the fiscal agency agreement, dated as of August 1, 1991, between us and The Bank of New York Mellon (formerly known as The Bank of New York) (as successor to JPMorgan Chase Bank, N.A.), as fiscal agent, as amended or supplemented from time to time (the “Fiscal Agency Agreement”). The fiscal agent will maintain a register for the Notes.

Payment of Principal and Interest

The 2021 Notes are initially limited to US$800,000,000 aggregate principal amount, and the 2023 Notes are initially limited to US$700,000,000 aggregate principal amount. The 2021 Notes will mature on June 1, 2021 (the “2021 Notes Maturity Date”), and the 2023 Notes will mature on June 1, 2023 (the “2023 Notes Maturity Date”, and together with the 2021 Notes Maturity Date, the “Maturity Dates”). The 2021 Notes will bear interest for each Interest Period (as defined below) at the rate equal to Three-Month USD LIBOR plus 0.575% per annum and the 2023 Notes will bear interest for each Interest Period at the rate equal to Three-Month USD LIBOR plus 0.775% per annum, in each case payable quarterly in arrears on March 1, June 1, September 1 and December 1 of each year (each an “Interest Payment Date”). The first interest payment on the Notes will be made on September 1, 2018 in respect of the period from (and including) June 1, 2018 to (but excluding) September 1, 2018. Interest on the Notes will accrue from June 1, 2018. If any Interest Payment Date or any Maturity Date falls on a day that is not a business day (as defined below), such date will be adjusted in accordance with the Modified Following Business Day Convention. The term “Modified Following Business Day Convention” means that the relevant date shall be postponed to the first following day that is a business day unless that day falls in the next calendar month in which case that date will be the first preceding day that is a business day. The term “business day” as used herein means a day other than a Saturday, a Sunday, or any other day on which banking institutions in The City of New York, London or Seoul are authorized or required by law or executive order to remain closed.

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 an Interest Payment Date for such Note. Interest on the Notes will be computed on the basis of the actual number of days in the applicable Interest Period (as defined herein) divided by 360. We will make principal and interest payments on the Notes in immediately available funds in U.S. dollars.

The term “Three-Month USD LIBOR” means, with respect to any Interest Determination Date (as defined below):

The Bank of New York Mellon will serve as the “Calculation Agent” for the Notes. In the absence of willful default, bad faith or manifest error, the Calculation Agent’s determination of Three-Month USD LIBOR and its calculation of the applicable interest rate for each Interest Period will be final and binding. The Calculation Agent will make available the interest rates for current and preceding Interest Periods by delivery of such notice through such medium as is available to participants in DTC, Euroclear and Clearstream, or any successor thereof, and in accordance with such applicable rules and procedures as long as the Notes are held in global form. In the event that the Notes are held in certificated form, the interest rates for current and preceding Interest Periods will be published in the manner described below under “—Notices”. We have the right to replace the Calculation Agent with the London office of another leading commercial bank or investment bank in New York or London. If the appointed office of the Calculation Agent is unable or unwilling to continue to act as the Calculation Agent or fails to determine the interest rate for any Interest Period, we have a duty to appoint the London office of such other leading commercial bank or investment bank in New York or London as may be approved in writing by the fiscal agent.

S-15

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 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 S.A./N.V. (“Euroclear”) or Clearstream Banking,société anonyme (“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.”

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 theSGX-ST and the rules of theSGX-ST so require, in the event that we issue the Notes in definitive form in the limited circumstances set forth in the accompanying prospectus, 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 we issue Notes in definitive form in the limited circumstances set forth in the accompanying prospectus, an announcement of such issue will be made by or on behalf of us through theSGX-ST. 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 any 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 the issuance would constitute a “qualified reopening” for U.S. federal income tax purposes or such additional debt securities would otherwise be part of the same “issue” for U.S. federal income tax purposes.

Notices

While the Notes are represented by the global note deposited with the custodian for DTC, notices to holders may be given by delivery to DTC, and such notices will be deemed to be given on the date of delivery to DTC. The fiscal agent may also mail notices by first-class mail, postage prepaid, to each registered holder’s last known address as it appears in the security register that the fiscal agent maintains. The fiscal agent will only mail these

S-16

notices to the registered holder of the Notes. You will not receive notices regarding the Notes directly from us unless we reissue the Notes to you in fully certificated form.

Neither the failure to give any notice to a particular holder, nor any defect in a notice given to a particular holder, will affect the sufficiency of any notice given to another holder.

S-17

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. DTC is owned by a number of its direct participants and by the New York Stock Exchange Inc., the American Stock Exchange, Inc. and the National Association of Securities Dealers Inc.

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 Notes through DTC, Euroclear and Clearstream

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. Financial institutions, acting as direct and indirect participants in DTC, will represent your beneficial interests in the Notes. These financial institutions will record the ownership and transfer of your beneficial interests through book-entry accounts. You may also 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. Euroclear and Clearstream will hold their 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.

S-18

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 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 participant would then either authorize you to take the action or act for you on your instructions.

DTC may grant proxies or authorize its participants, or persons holding beneficial interests in the Notes through such 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.

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 topre-position funds (i.e., have funds in place at Euroclear or Clearstream before the value date), either from cash on hand or existing 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.

S-19

As an alternative, if Euroclear or Clearstream has extended a line of credit to a participant, the participant may decide not topre-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 Notes which the participant earns during thatone-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 usingfree-of-payment transfers to move the Notes, but funds movement will take place separately.

S-20

TAXATION

Korean Taxation

For a discussion of Korean tax considerations that may be relevant to you if you invest in the Notes, please refer to the section “Taxation—Korean Taxation” in the accompanying prospectus.

United States Tax Considerations

Stated interest on the Notes will be treated as qualified stated interest for U.S. federal income tax purposes. Under certain circumstances as described under “Taxation—Korean Taxation” in the accompanying prospectus, a U.S. holder may be subject to Korean withholding tax upon the sale or other disposition of Notes. A U.S. holder eligible for benefits of the Korea-U.S. tax treaty, which exempts capital gains from tax in Korea, would not be eligible to credit against its U.S. federal income tax liability any such Korean tax withheld. U.S. holders should consult their own tax advisers with respect to their eligibility for benefits under the Korea-U.S. tax treaty and, in the case of U.S. holders that are not eligible for treaty benefits, their ability to credit any Korean tax withheld upon sale of the Notes against their U.S. federal income tax liability.

For a discussion of additional U.S. federal income tax considerations that may be relevant to you if you invest in the Notes and are a U.S. holder, see “Taxation—United States Tax Considerations” in the accompanying prospectus.

UNDERWRITING

Relationship with the Underwriters

We and the underwriters named below (the “Underwriters”) have entered into a Terms Agreement dated May 23, 2018 (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 each of the Underwriters has severally agreed to purchase, the following principal amount of the Notes set out opposite its name below:

Name of the Underwriters	Principal Amount of 2021 Notes		Principal Amount of 2023 Notes
Citigroup Global Markets Inc.	US$	133,334,000	US$	116,666,000
ING Bank N.V., Singapore Branch		133,334,000		116,666,000
J.P. Morgan Securities LLC		133,333,000		116,667,000
The Korea Development Bank		133,333,000		116,667,000

KEXIM Bank (UK) Limited		—		—
	US$	800,000,000	US$	700,000,000

Each of The Korea Development Bank and KEXIM Bank (UK) Limited, both Underwriters, is an affiliate of ours 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 Notes of a series, 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. 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 behalf of us in such jurisdiction.

The Notes are a new class of securities with no established trading market. Applications will be made to the SGX-ST for the listing and quotation of the Notes on the SGX-ST. 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.

In connection with this offering, each of the Underwriters (the “Stabilizing Managers”) or any person acting on their behalf may purchase and sell the Notes in the open market. These transactions may include over-allotment, covering transactions and stabilizing transactions. Over-allotment involves sales of the Notes in excess

S-22

of the principal amount of the 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. Stabilizing transactions consist of certain bids or purchases of the Notes made 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 Managers may conduct these transactions in theover-the-counter market or otherwise. If the Stabilizing Managers commence any of these transactions, they may discontinue such transactions at any time, and must discontinue them after a limited period.

The amount of net proceeds from our 2021 Notes is US$797,600,000 after deducting underwriting discounts but not estimated expenses. Our expenses associated with the 2021 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 2021 Notes.

The amount of net proceeds from our 2023 Notes is US$697,900,000 after deducting underwriting discounts but not estimated expenses. Our expenses associated with the 2023 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 2023 Notes.

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 its or 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).

Delivery of the Notes

We expect to make delivery of the Notes, against payment insame-day funds on or about June 1, 2018, which we expect will be the sixth business day following the date of this prospectus supplement. Under Rule 15c6-l promulgated under the Securities Exchange Act of 1934, as amended, U.S. purchasers are generally required to settle trades in the secondary market in two business days, 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 second business day before the settlement date, because the Notes will initially settle in T+6, 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.
