United States Dollar Floating Rate Bonds due August 2028

Export Development Canada will pay interest on the bonds quarterly in arrears on February 1, May 1, August 1 and November 1 of each year, commencing on November 1, 2024. Interest will accrue from August 1, 2024. EDC cannot redeem the bonds prior to maturity unless certain events occur involving Canadian taxation as further described in “Description of Bonds—Maturity, Redemption and Purchases”. The bonds will mature on August 1, 2028.

The bonds will constitute direct unconditional obligations of EDC and as such will carry the full faith and credit of Canada and will constitute direct unconditional obligations of and by Canada.

Application has been made for the bonds offered by this prospectus supplement to be admitted to the Official List of the Luxembourg Stock Exchange and for such bonds to be admitted to trading on the Euro MTF Market of the Luxembourg Stock Exchange. Unless the context otherwise requires, references in this prospectus supplement to the bonds being “listed” shall mean that the bonds have been admitted to trading on the Euro MTF Market and have been admitted to the Official List of the Luxembourg Stock Exchange. The Euro MTF Market of the Luxembourg Stock Exchange is not a regulated market for purposes of the Markets in Financial Instruments Directive 2014/65/EU (“MiFID II”). The Underwriters will purchase all of the bonds if any are purchased.

(1) Plus accrued interest from August 1, 2024, if settlement occurs after such date.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

This prospectus supplement is not an approved prospectus pursuant to Regulation (EU) 2017/1129 (the “Prospectus Regulation”) or Regulation (EU) 2017/1129 as it forms part of United Kingdom domestic law by virtue of the European Union (Withdrawal) Act 2018 (“EUWA”) (the “UK Prospectus Regulation”), as applicable. In the European Economic Area (the “EEA”) the bonds may only be offered to qualified investors (as defined in the Prospectus Regulation). In the United Kingdom (the “UK”) the bonds may only be offered to qualified investors (as defined in the UK Prospectus Regulation). This prospectus supplement together with the prospectus dated March 14, 2022 does, however, constitute an admission document for the purposes of admission of the bonds to the Official List of the Luxembourg Stock Exchange and admission to trading of the bonds on the Euro MTF Market in accordance with the rules and regulations of the Luxembourg Stock Exchange.

We expect that the bonds will be ready for delivery in book-entry form only through The Depository Trust Company, CDS Clearing and Depository Services Inc., Clearstream Banking S.A. or Euroclear Bank SA/NV, as the case may be, on or about August 1, 2024.

Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the bonds has led to the conclusion that: (i) the target market for the bonds is eligible counterparties and professional clients only, each as defined in MiFID II; and (ii) all channels for distribution of the bonds to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the bonds (a “distributor”) should take into consideration the manufacturers’ target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the bonds (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

Solely for the purposes of the product approval process of any relevant underwriter that considers itself a manufacturer pursuant to the FCA Handbook Product Intervention and Product Governance Sourcebook (the “UK MiFIR Product Governance Rules”) (each a “UK Manufacturer” and, together, the “UK Manufacturers”), the target market assessment in respect of the bonds has led to the conclusion that: (i) the target market for the bonds is only eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook (“COBS”), and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of United Kingdom domestic law by virtue of the European Union (Withdrawal) Act 2018 (“UK MiFIR”); and (ii) all channels for distribution of the bonds to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the bonds (a “UK distributor”) should take into consideration the manufacturers’ target market assessment; however, a distributor subject to the UK MiFIR Product Governance Rules is responsible for undertaking its own target market assessment in respect of the bonds (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

RISK FACTORS

Compounded SOFR with respect to a particular interest period will only be capable of being determined near the end of the relevant interest period.

The level of Compounded SOFR applicable to a particular interest period and, therefore, the amount of interest payable with respect to such interest period will be determined on the interest determination date for such interest period.

Because each such date is near the end of such interest period, you will not know the amount of interest payable with respect to a particular interest period until shortly prior to the related interest payment date and it may be difficult for you to reliably estimate the amount of interest that will be payable on each such interest payment date. In addition, some investors may be unwilling or unable to trade the bonds without changes to their information technology systems. An inability to reliably estimate accrued and unpaid interest as well as potential need for some investors to change their information technology systems could both adversely impact the liquidity and trading price of the bonds.

S-6

DESCRIPTION OF BONDS

General

The United States Dollar Floating Rate Bonds due August 2028 in the initial aggregate principal amount of U.S. $1,000,000,000 will be issued subject to a fiscal and paying agency agreement to be dated as of August 1, 2024 (the “Fiscal Agency Agreement”) between EDC and Citibank, N.A., as fiscal agent, calculation agent, transfer agent, registrar and principal paying agent (the “Registrar”).

The terms and conditions of the bonds are summarized below and are subject to the detailed provisions of the Fiscal Agency Agreement and the exhibits thereto, including the form of the global bonds, a copy of which will be incorporated by reference as an exhibit to registration statement no. 333-261836. The bonds and the Fiscal Agency Agreement together constitute a contract, all of the terms and conditions of which the registered holder, by acceptance of the bonds, assents to and is deemed to have notice of. Additional terms of the bonds are described in the accompanying basic prospectus under the heading “Description of the Debt Securities”.

References to principal and interest in respect of the bonds shall be deemed also to refer to any Additional Amounts which may be payable. See “Description of the Debt Securities—Payment of Additional Amounts” in the accompanying basic prospectus.

Status of the Bonds

The bonds will constitute direct unconditional obligations of EDC and as such will carry the full faith and credit of Canada and will constitute direct unconditional obligations of and by Canada. Payments of the principal of and interest on the bonds will constitute a charge on and be payable out of the Consolidated Revenue Fund of Canada. The obligations of EDC under the bonds rank equally with all of EDC’s other unsecured and unsubordinated indebtedness and obligations from time to time outstanding.

Form, Denomination and Registration

The bonds will be issued in the form of one or more fully registered global bonds registered in the name of Cede & Co., as nominee of DTC. Beneficial interests in the global bonds will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may elect to hold interests in the global bonds directly through any of DTC (in the United States), CDS (in Canada) or Clearstream, Luxembourg or Euroclear (in Europe) if they are participants in such systems, or indirectly through organizations which are participants in such systems. CDS will hold interests on behalf of its participants directly through its account at DTC, and Clearstream, Luxembourg and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositaries (the “U.S. Depositaries”), which in turn will hold such interests in customers’ securities accounts in the names of the U.S. Depositaries on the books of DTC. Except in the limited circumstances described herein, owners of beneficial interests in the global bonds will not be entitled to have bonds registered in their names, will not receive or be entitled to receive physical delivery of bonds in definitive form and will not be considered owners or holders thereof under the Fiscal Agency Agreement. See “Title” and “Definitive Certificates”.

Bonds will only be sold in minimum denominations of U.S. $5,000 and integral multiples of U.S. $5,000.

All bonds will be recorded in a register maintained by the Registrar, and will be registered in the name of Cede & Co., for the benefit of owners of beneficial interests in the global bonds, including participants in DTC, CDS, Clearstream, Luxembourg and Euroclear.

The Registrar will be responsible for (i) maintaining a record of the aggregate holdings of the global bonds of Cede & Co.; (ii) ensuring that payments of principal and interest in respect of the global bonds received by the Registrar from EDC are duly credited to Cede & Co.; and (iii) transmitting to EDC any notices from the registered holders of bonds.

S-7

The Registrar will not impose any fees in respect of the bonds, other than reasonable fees for the replacement of lost, stolen, mutilated or destroyed bonds. However, owners of beneficial interests in the global bonds may incur fees payable in respect of the maintenance and operation of the book-entry accounts in which such interests are held with the clearing systems.

Title

Subject to applicable law and the terms of the Fiscal Agency Agreement, EDC and the Registrar will treat the persons in whose name a global bond is registered, initially Cede & Co., as nominee for DTC, as the owner of such global bond for the purpose of receiving payments of principal and interest on the bonds and for all other purposes whatsoever, except in respect of the payment of Additional Amounts. Therefore, neither EDC nor the Registrar has any direct responsibility or liability for the payment of principal or interest on the bonds to owners of beneficial interests in a global bond.

Interest

The bonds will bear interest from August 1, 2024 at a floating rate per annum equal to Compounded SOFR plus 0.33%. Interest on the bonds will be payable in four quarterly installments in arrears on February 1, May 1, August 1 and November 1 of each year (each an “interest payment date”), commencing November 1, 2024. If any interest payment date would otherwise fall on a day which is not a business day, then such date shall be postponed to the next day which is a business day. In this paragraph “business day” means a day on which banking institutions in the City of New York, the City of London, England, the City of Toronto are not authorized or obligated by law or executive order to be closed.

Interest will be payable to the persons in whose names the bonds are registered at the close of business on January 15, April 15, July 15, or October 15 (the regular record dates), as the case may be, preceding the applicable interest payment date. Interest on the bonds will cease to accrue on the date fixed for redemption or repayment unless payment of principal is improperly withheld or refused. Any overdue principal or interest on the bonds shall bear interest at the rate of Compounded SOFR plus 0.33% per annum (before as well as after judgment) until paid, or if earlier, when the full amount of the moneys payable has been received by the Registrar and notice to that effect has been given in accordance with “Notices” below.

Whenever it is necessary to compute any amount of accrued interest in respect of the bonds for a period of less than one full year, other than with respect to regular quarterly interest payments, such interest shall be calculated on the basis of a 360-day year and the actual number of days in the Observation Period (as defined below).

The rate of interest applicable for an interest period will be determined on the applicable interest determination date by the Calculation Agent as further described herein.

Secured Overnight Financing Rate and the SOFR Index

SOFR is published by the Federal Reserve Bank of New York and is intended to be a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities.

The SOFR Index is published by the Federal Reserve Bank of New York and measures the cumulative impact of compounding SOFR on a unit of investment over time, with the initial value set to 1.00000000 on April 2, 2018, the first value date of SOFR. The SOFR Index value reflects the effect of compounding SOFR each business day and allows the calculation of compounded SOFR averages over custom time periods.

The Federal Reserve Bank of New York notes on its publication page for the SOFR Index that use of the SOFR Index is subject to important limitations, indemnification obligations and disclaimers, including that the Federal Reserve Bank of New York may alter the methods of calculation, publication schedule, rate revision practices or availability of the SOFR Index at any time without notice. The interest rate for any interest period will not be adjusted for any modifications or amendments to the SOFR Index or SOFR data that the Federal Reserve Bank of New York may publish after the interest rate for that interest period has been determined.

S-8

Compounded SOFR

“Compounded SOFR” will be determined by the Calculation Agent in accordance with the following formula (and the resulting percentage will be rounded, if necessary, to the fifth decimal place, with 0.000005 being rounded upwards):

where:

“d_c” is the number of calendar days in the relevant Observation Period;

“SOFR Index_Start” = For periods other than the initial interest period, the SOFR Index value on the preceding Interest Payment Determination Date, and, for the initial interest period, the SOFR Index value on July 25, 2024;

“SOFR Index_End” = The SOFR Index value on the Interest Payment Determination Date relating to the applicable Interest Payment Date (or in the final interest period, relating to the applicable maturity date).

For the purposes of determining Compounded SOFR:

“Interest Payment Determination Date” means the date five (5), U.S. Government Securities Business Days before each Interest Payment Date.

“Observation Period” means, in respect of each interest period, the period from, and including, the date five (5) U.S. Government Securities Business Days preceding the first date in such interest period to, but excluding, the date five (5) U.S. Government Securities Business Days preceding the interest payment date for such interest period (or in the final interest period, preceding the applicable maturity date).

“SOFR Index” means with respect to any U.S. Government Securities Business Day:

SOFR Index Unavailable

If under clause (2)(i) of the definition of “SOFR Index” the SOFR Index value does not appear and if we (upon notification from the Calculation Agent where appropriate) determine that a Benchmark Transition Event has not occurred in relation to a Benchmark when the rate of interest (or any component part thereof) remains to be determined by reference to that Benchmark, then the following provisions of this subsection shall apply.

If a SOFR Index_Startor SOFR Index_End is not published on the associated Interest Payment Determination Date and a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, “SOFR” means, for the applicable interest period for which such index is not available, the rate

S-9

of return on a daily compounded interest investment calculated in accordance with the formula for SOFR Averages, and definitions required for such formula, published on the SOFR Administrator’s Website at https://www.newyorkfed.org/markets/treasury-repo-reference-rates-information. For the purposes of this provision, references in the SOFR Averages compounding formula and related definitions to “calculation period” shall be replaced with “Observation Period” and the words “that is, 30-, 90-, or 180- calendar days” shall be removed. If SOFR does not so appear for any day, “i” in the Observation Period, SOFR_i for such day “i” shall be SOFR published in respect of the first preceding U.S. Government Securities Business Day for which SOFR was published on the SOFR Administrator’s Website.

Effect of a Benchmark Transition Event

If we or our designee determine that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time (as defined below) in respect of any determination of the Benchmark on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the floating rate notes in respect of such determination on such date and all determinations on all subsequent dates.

In connection with the implementation of a Benchmark Replacement, we or our designee will have the right to make Benchmark Replacement Conforming Changes from time to time.

Any determination, decision or election that may be made by us or our designee pursuant to the benchmark replacement provisions described herein, including any determination with respect to tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection:

Any determination, decision or election pursuant to the benchmark replacement provisions shall be made by us or our designee (which may be our affiliate) on the basis as described above. The Calculation Agent shall have no liability for not making any such determination, decision or election.

Certain Defined Terms

“Benchmark” means, initially, SOFR; provided that if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to SOFR (or the published SOFR Index used in the calculation thereof) or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by us or our designee as of the Benchmark Replacement Date:

S-10

“Benchmark Replacement Adjustment” means the first alternative set forth in the order below that can be determined by us or our designee as of the Benchmark Replacement Date:

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definitions or interpretations of interest period, the timing and frequency of determining rates and making payments of interest, the rounding of amounts or tenors, and other administrative matters) that we or our designee decide may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if we or our designee decide that adoption of any portion of such market practice is not administratively feasible or if we or our designee determine that no market practice for use of the Benchmark Replacement exists, in such other manner as we or our designee determine is reasonably practicable).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then- current Benchmark (including any daily published component used in the calculation thereof):

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark (including the daily published component used in the calculation thereof):

S-11

“ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment.

“Reference Time” with respect to any determination of the Benchmark means (1) if the Benchmark is Compounded SOFR, the SOFR Index Determination Time, as such time is defined above, and (2) if the Benchmark is not Compounded SOFR, the time determined by us or our designee in accordance with the Benchmark Replacement Conforming Changes.

S-12

(60) days’ written notice to us. All determinations made by the Calculation Agent shall, in the absence of manifest error, be conclusive for all purposes and binding on us and the holders of the floating rate notes. So long as Compounded SOFR is required to be determined with respect to the floating rate notes, there will at all times be a Calculation Agent. In the event that any then acting Calculation Agent shall be unable or unwilling to act, or that such Calculation Agent shall fail duly to establish Compounded SOFR for any interest period, or we propose to remove such Calculation Agent, we shall appoint another Calculation Agent.

None of the Registrar and the Calculation Agent shall be under any obligation (i) to monitor, determine or verify the unavailability or cessation of SOFR or the SOFR Index, or whether or when there has occurred, or to give notice to any other transaction party of the occurrence of, any Benchmark Transition Event or related Benchmark Replacement Date, (ii) to select, determine or designate any Benchmark Replacement, or other successor or replacement benchmark index, or whether any conditions to the designation of such a rate or index have been satisfied, (iii) to select, determine or designate any Benchmark Replacement Adjustment, or other modifier to any replacement or successor index, or (iv) to determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing.

None of the Registrar and the Calculation Agent shall be liable for any inability, failure or delay on its part to perform any of its duties set forth in this preliminary prospectus supplement as a result of the unavailability of SOFR, the SOFR Index or other applicable Benchmark Replacement, including as a result of any failure, inability, delay, error or inaccuracy on the part of any other transaction party in providing any direction, instruction, notice or information required or contemplated by the terms of this preliminary prospectus supplement and reasonably required for the performance of such duties.

Payments

Principal of and interest on the bonds (including bonds in definitive form issued in exchange for the global bond as described under “Definitive Certificates”) are payable by EDC in United States dollars to the persons in whose names the bonds are registered on the record date preceding any interest payment date or at maturity, as the case may be. The Registrar will act as EDC’s principal paying agent for the bonds pursuant to the Fiscal Agency Agreement. In the event definitive bonds are issued, EDC will appoint and maintain a transfer and paying agent in Luxembourg as further described under “Definitive Certificates”. Ownership positions within each clearing system will be determined in accordance with the normal conventions observed by such system. Neither EDC nor the Registrar will have any responsibility or liability for any aspect of the records of DTC, CDS, Clearstream, Luxembourg or Euroclear relating to or payments made by such clearing systems on account of beneficial interests in a global bond or for maintaining, supervising or reviewing any records of such clearing systems relating to such beneficial interests.

If any date for payment in respect of any bond is not a business day, the holder thereof shall not be entitled to payment until the next following business day. In this paragraph “business day” means a day on which banking institutions in the City of New York, the City of London, England, the City of Toronto or in the applicable place of payment are not authorized or obligated by law or executive order to be closed.

All funds held by the Registrar or any paying agent for payment of principal or interest and any Additional Amounts shall be held in trust for the registered holders of bonds. Any such moneys remaining unclaimed at the end of two years after the date on which such principal, interest or Additional Amounts shall have become due and payable shall be repaid to EDC, as provided and in the manner set forth in the bonds.

Further Issues

EDC may from time to time, without notice to or the consent of the registered holders of the bonds, create and issue further bonds ranking equally with the bonds being issued pursuant to this prospectus supplement in all

respects (or in all respects except for the payment of interest accruing prior to the issue date of such further bonds or except for the first payment of interest following the issue date of such further bonds) and so that such further bonds shall be consolidated and form a single series with the bonds and shall have the same terms as to status,

S-13

redemption or otherwise as the bonds. Any further bonds shall be issued subject to an agreement supplemental to the Fiscal Agency Agreement.

EDC will not issue any additional bonds that have the same CUSIP, ISIN or other identifying number as the outstanding bonds offered hereby unless the additional bonds and the outstanding bonds are fungible for Canadian and U.S. federal income tax purposes.

Maturity, Redemption and Purchases

The principal amount of the bonds shall be due and payable on August 1, 2028. The bonds are not subject to any sinking fund, are not redeemable at the option of EDC prior to maturity unless certain events occur involving Canadian taxation as provided below and are not repayable at the option of the holder prior to maturity.

The bonds may be redeemed at the option of EDC in whole, but not in part, at any time, on giving not less than 10 days’ and not more than 60 days’ notice to registered holders of bonds in accordance with “Notices” below (which notice shall be irrevocable), at 100% of the principal amount thereof, together with accrued and unpaid interest thereon to the date fixed for redemption, if (a) EDC has or will become obliged to pay Additional Amounts as provided in the accompanying basic prospectus under the caption “Description of the Debt Securities—Payment of Additional Amounts” as a result of any change in, or amendment to, the laws or regulations of Canada, or any province or political subdivision thereof, or any authority thereof or agency therein having power to tax, or any change in the application or official interpretation of such laws or regulations, which change or amendment becomes effective on or after the date of this prospectus supplement, and (b) such obligation cannot be avoided by EDC taking reasonable measures available to it, provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which EDC would be obliged to pay such Additional Amounts were a payment in respect of the bonds then due. Prior to the publication of any notice of redemption pursuant to this paragraph, EDC shall deliver to the Registrar a certificate signed by an officer of EDC stating that EDC is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of EDC so to redeem have occurred.

EDC may, if not in default under the bonds, at any time purchase bonds in the open market, or by tender or by private contract at any price and may cause the Registrar to cancel any bonds so purchased.

Definitive Certificates

No beneficial owner of bonds will be entitled to receive physical delivery of bonds in definitive form except in the limited circumstances described below.

If DTC notifies EDC that it is unwilling or unable to continue as depositary in connection with the global bonds or ceases to be a recognized clearing agency registered under the U.S. Securities Exchange Act of 1934, as amended, and a successor depositary is not appointed by EDC within 90 days after receiving such notice or becoming aware that DTC is no longer so registered, EDC will issue or cause to be issued fully registered bonds in definitive form upon registration of, transfer of, or in exchange for, the global bonds. EDC may also at any time and in its sole discretion determine not to have any of the bonds held in the form of a global bond and, in such event, will issue or cause to be issued fully registered bonds in definitive form upon registration of, transfer of, or in exchange for, such global bond. In the event definitive bonds are issued and for so long as the bonds are listed on the Luxembourg Stock Exchange, and the rules of the Luxembourg Stock Exchange so require, EDC will appoint and maintain a transfer and paying agent in Luxembourg and notice of such appointment will be published in a leading newspaper having general circulation in Luxembourg (which is expected to be the Luxemburger Wort) or on the Luxembourg Stock Exchange website at www.luxse.com.

Fully registered bonds in definitive form may be presented at the office of the Luxembourg transfer agent, for registration of transfer or exchange by the Registrar in accordance with the Fiscal Agency Agreement. Payments of interest on fully registered bonds in definitive form will be made by the Registrar by cheque or wire transfer in accordance with the Fiscal Agency Agreement. Fully registered bonds in definitive form may be surrendered at the office of the Luxembourg paying agent or such other paying agent appointed by EDC for payment of principal at maturity or on the date fixed for redemption.

S-14

Modification

The Fiscal Agency Agreement and the bonds may be amended or supplemented by EDC on the one hand, and the Registrar, on the other hand, without notice to or the consent of the registered holder of any bond, for the purpose of curing any ambiguity, or curing, correcting or supplementing any defective provisions contained therein, or effecting the issue of further bonds as described under “Further Issues” above, or in any other manner which EDC may deem necessary or desirable and which, in the reasonable opinion of EDC, on the one hand, and the Registrar, on the other hand, will not adversely affect the interests of the holders of bonds.

The Fiscal Agency Agreement will contain provisions for convening meetings of registered holders of bonds to modify or amend by Extraordinary Resolution (as defined below) the Fiscal Agency Agreement (except as provided in the immediately preceding paragraph) and the bonds (including the terms and conditions thereof). An Extraordinary Resolution in the form of a resolution duly passed at any such meeting shall be binding on all holders of bonds, whether present or not, and an Extraordinary Resolution in the form of an instrument signed by the holders of the bonds in accordance with the definition below shall be binding on all holders of the bonds; provided, however, that no such modification or amendment to the Fiscal Agency Agreement or to the terms and conditions of the bonds may, without the consent of the registered holder of each such bond affected thereby: (a) change the stated maturity of any such bond or change any interest payment date; (b) reduce the principal amount of any such bond or the rate of interest payable thereon; (c) change the currency of payment of any such bond; (d) impair the right to institute suit for the enforcement of any payment on or with respect to any such bond; or (e) reduce the percentage of the principal amount of bonds necessary for the taking of any action, including modification or amendment of the Fiscal Agency Agreement or the terms and conditions of the bonds, or reduce the quorum required at any meeting of registered holders of bonds.

The term “Extraordinary Resolution” will be defined in the Fiscal Agency Agreement as a resolution passed at a meeting of registered holders of bonds by the affirmative vote of the registered holders of not less than 66²⁄₃% of the principal amount of the bonds represented at the meeting in person or by proxy and voted on the resolution or as an instrument in writing signed by the registered holders of not less than 66²⁄₃% in principal amount of the outstanding bonds. The quorum at any such meeting for passing an Extraordinary Resolution will be one or more registered holders of bonds present in person or by proxy who represent at least a majority in principal amount of the bonds at the time outstanding, or at any adjourned meeting called by EDC or the Registrar, one or more persons being or representing registered holders of bonds whatever the principal amount of the bonds so held or represented.

So long as the bonds are listed on the Luxembourg Stock Exchange, notice of any amendment will be published in a leading newspaper having general circulation in Luxembourg (which is expected to be the Luxemburger Wort) or on the Luxembourg Stock Exchange website at www.luxse.com.

Amendments to the Basic Prospectus

The terms and conditions of the debt securities described in the accompanying basic prospectus under the caption “Description of the Debt Securities—Payment of Additional Amounts” will be amended to delete subparagraph (a) and replace it with the following:

Governing Law

The bonds and the Fiscal Agency Agreement will be governed by, and interpreted in accordance with, the laws of the Province of Ontario, Canada and the laws of Canada applicable therein.

S-15

Notices

All notices to the registered holders of bonds will be mailed or delivered to such holders at their addresses indicated in records maintained by the Registrar and, as long as the bonds are listed on the Luxembourg Stock Exchange, and the rules of the Luxembourg Stock Exchange so require, notices will be published in a leading newspaper having general circulation in Luxembourg (which is expected to be the Luxemburger Wort) or on the Luxembourg Stock Exchange website at www.luxse.com. Any such notice shall be deemed to have been given on the date of such delivery or publication, as the case may be, or in the case of mailing, on the second business day after such mailing.

Prescription

EDC’s obligation to pay the principal and interest on the bonds will cease if the bonds are not presented for payment within a period of two years, and a claim for interest is not made within two years, from the date on which such principal or interest, as the case may be, becomes due and payable.

S-16

CLEARING AND SETTLEMENT

Links have been established among DTC, CDS, Clearstream, Luxembourg and Euroclear to facilitate the initial issuance of the bonds and cross-market transfers of the bonds associated with secondary market trading. DTC will be directly linked to CDS, and indirectly linked to Clearstream, Luxembourg and Euroclear through the DTC accounts of their respective U.S. Depositaries.

The Clearing Systems

The clearing systems have advised EDC as follows:

DTC. DTC is a limited-purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the U.S. Securities Exchange Act of 1934, as amended. DTC was created to hold securities for DTC participants (“DTC Participants”) and to facilitate the clearance and settlement of transactions between DTC Participants through electronic book-entry changes in accounts of DTC Participants, thereby eliminating the need for physical movement of certificates. DTC Participants include certain of the Underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Indirect access to the DTC system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (“Indirect DTC Participants”).

Transfers of ownership or other interests in bonds in DTC may be made only through DTC Participants. Indirect DTC Participants are required to effect transfers through a DTC Participant. In addition, beneficial owners of bonds in DTC will receive all distributions of principal of and interest on the bonds through such DTC Participants to the extent received by DTC. Distributions in the United States will be subject to tax reporting in accordance with relevant United States tax laws and regulations. See “Tax Matters—Certain U.S. Federal Income Tax Considerations” in the accompanying basic prospectus.

Because DTC can only act on behalf of DTC Participants, who in turn act on behalf of Indirect DTC Participants, and because beneficial owners holding through DTC will hold interests in the bonds through DTC Participants or Indirect DTC Participants, the ability of such beneficial owners to pledge bonds to persons or entities that do not participate in DTC, or otherwise take actions with respect to such bonds, may be limited.

CDS. CDS was formed in November 2006 pursuant to the restructuring of The Canadian Depository for Securities Limited (“CDS Ltd.”). After the restructuring, CDS Ltd., founded in 1970, remains the holding company for CDS and two other operating subsidiaries and is Canada’s national securities clearing and depositary services organization. Functioning as a service utility for the Canadian financial community, CDS provides a variety of computer-automated services for financial institutions and investment dealers active in domestic and international capital markets. CDS participants (“CDS Participants”) include banks (including their Canadian subcustodians), investment dealers and trust companies and may include certain of the Underwriters. Indirect access to CDS is available to other organizations that clear through or maintain a custodial relationship with a CDS Participant. Transfers of ownership and other interests, including cash distributions, in the bonds in CDS may only be processed through CDS Participants and will be completed in accordance with existing CDS rules and procedures. CDS operates in Montreal, Toronto, Calgary and Vancouver to centralize securities clearing functions through a central securities depositary.

CDS is wholly owned by CDS Ltd., a private corporation wholly owned by the TMX Group Limited. CDS is the exclusive clearing house for equity trading on the Toronto Stock Exchange and also clears a substantial volume of “over the counter” trading in equities and bonds.

Clearstream, Luxembourg. Clearstream, Luxembourg is incorporated under the laws of Luxembourg as a registered bank. Clearstream, Luxembourg holds securities for its participating organizations (“Clearstream, Luxembourg Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream, Luxembourg Participants through electronic book-entry changes in accounts of Clearstream, Luxembourg Participants, thereby eliminating the need for physical movement of certificates. Clearstream,

S-17

Luxembourg provides to Clearstream, Luxembourg Participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream, Luxembourg interfaces with domestic markets in several countries. As a registered bank in Luxembourg, Clearstream, Luxembourg is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream, Luxembourg Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations and may include the Underwriters. Indirect access to Clearstream, Luxembourg is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream, Luxembourg Participant either directly or indirectly.

Distributions with respect to interests in the bonds held beneficially through Clearstream, Luxembourg will be credited to cash accounts of Clearstream, Luxembourg Participants in accordance with its rules and procedures, to the extent received by the U.S. Depositaries for Clearstream, Luxembourg. Clearstream, Luxembourg has established an electronic bridge with Euroclear in Brussels to facilitate settlement of trades between Clearstream, Luxembourg and Euroclear.

Euroclear. Euroclear was created in 1968 to hold securities for participants of Euroclear (“Euroclear Participants”) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear includes various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank SA/NV (the “Euroclear Operator”), under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the “Cooperative”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the Underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

The Euroclear Operator is regulated and examined by the Belgian Banking and Finance Commission. Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants, and has no record of or relationship with persons holding through Euroclear Participants.

Distributions with respect to bonds held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions, to the extent received by the U.S. Depositary for Euroclear.

Global Clearance and Settlement Procedures

Secondary market trading between DTC Participants will occur in the ordinary way in accordance with DTC rules. Secondary market trading between CDS Participants will be in accordance with market conventions applicable to transactions in book-based Canadian domestic bonds. Secondary market trading between Clearstream, Luxembourg Participants and/or Euroclear Participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream, Luxembourg and Euroclear.

Transfers Between DTC and CDS, Clearstream, Luxembourg or Euroclear.  Cross-market transfers between persons holding directly or indirectly through DTC Participants, on the one hand, and directly or

S-18

indirectly through CDS Participants, Clearstream, Luxembourg Participants or Euroclear Participants, on the other, will be effected in DTC in accordance with DTC rules; however, such cross-market transactions will require delivery of instructions to the relevant clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines. The relevant clearing system will, if the transaction meets its settlement requirements, deliver instructions to DTC directly or through its U.S. Depositary to take action to effect final settlement on its behalf by delivering or receiving bonds in DTC, and making or receiving payment in accordance with normal procedures for settlement in DTC. CDS Participants, Clearstream, Luxembourg Participants and Euroclear Participants may not deliver instructions directly to DTC or the respective U.S. Depositary of Clearstream, Luxembourg or Euroclear.

Because of time-zone differences, credits of bonds received in Clearstream, Luxembourg or Euroclear as a result of a transaction with a DTC Participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in such bonds settled during such processing will be reported to the relevant Clearstream, Luxembourg Participant or Euroclear Participant on such business day. Cash received in Clearstream, Luxembourg or Euroclear as a result of sales of bonds by or through a Clearstream, Luxembourg Participant or a Euroclear Participant to a DTC Participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream, Luxembourg or Euroclear cash account only as of the business day following settlement in DTC.

Transfers Between Clearstream, Luxembourg, Euroclear and CDS. Cross-market transfers between Clearstream, Luxembourg Participants, Euroclear Participants and CDS Participants will be effected in DTC.

When bonds are to be transferred from the account of a CDS Participant to the account of a Clearstream, Luxembourg Participant or Euroclear Participant, the CDS Participant will transmit instructions to CDS on settlement date. The Clearstream, Luxembourg Participant or Euroclear Participant will transmit instructions to Clearstream, Luxembourg or Euroclear at least one business day prior to settlement date. One business day prior to settlement date Clearstream, Luxembourg, and on settlement date Euroclear, will transmit trade instructions to its respective U.S. Depositary. The beneficial interests in the bonds and payments for such beneficial interests will be transferred in DTC by CDS and the respective U.S. Depositary for Clearstream, Luxembourg and Euroclear.

Although DTC, CDS, Clearstream, Luxembourg and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of bonds among participants of DTC, CDS, Clearstream, Luxembourg and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be changed or discontinued at any time.

TAX MATTERS

Canadian Federal Income Tax Consequences

The following summary supplements the discussion under “Tax Matters—Canadian Federal Income Tax Consequences” in the accompanying base prospectus, to which reference is hereby made.

In the opinion of Stikeman Elliott LLP, Canadian counsel for the Underwriters, the following is a fair summary of the principal Canadian federal income tax considerations generally applicable at the date hereof to a person who acquires beneficial ownership of a bond pursuant to this prospectus supplement and who at all relevant times, for purposes of the Income Tax Act (Canada) (the “Tax Act”) holds the bond as capital property and deals at arm’s length with EDC and any prospective purchaser of the bond. Generally, a bond will be considered to be capital property to a person provided that the person does not hold the bond in the course of carrying on a business of buying and selling securities and has not acquired the bond as an adventure in the nature of trade (“Holder”).

This summary is based upon: (a) the current provisions of the Tax Act and the regulations thereunder (the “Regulations”) in force as of the date hereof, (b) all specific proposals to amend the Tax Act or the Regulations that have been publicly announced by, or on behalf of, the Minister of Finance (Canada) prior to the date hereof (the “Tax Proposals”), and (c) counsel’s understanding of the published administrative policies and assessing practices of the Canada Revenue Agency (the “CRA”). This summary assumes that the Tax Proposals will be enacted as currently proposed, but no assurance can be given that this will be the case. This summary is not exhaustive of all possible Canadian federal income tax considerations and, except for the Tax Proposals, does not take into account or anticipate any changes in law or in the administrative or assessing policies and practices of the CRA, whether by legislative, governmental or judicial action, nor does it take into account provincial, territorial or foreign tax considerations. No assurances can be given that changes in the law or administrative practices or future court decisions will not affect the Canadian federal income tax treatment of a Holder. This summary discusses the tax considerations applicable to persons who purchase bonds upon their initial offering and does not discuss the tax considerations applicable to subsequent purchasers of bonds. The discussion does not address debt securities issued with original issue discount or other special features and investors should consult their own tax advisors in this regard.

In general, for the purposes of the Tax Act, all amounts not otherwise expressed in Canadian dollars must be converted into Canadian dollars based on the daily average exchange rate as quoted by the Bank of Canada for the applicable day or such other rate of exchange that is acceptable to the CRA.

This summary is of a general nature only and is not intended to be, nor should it be considered to be, legal or tax advice to any particular Holder and no representation with respect to the consequences to any particular Holder is made. Therefore, each Holder should consult its own tax advisors for advice regarding its particular circumstances.

Investors Resident in Canada

The following section of this summary is applicable to a Holder who, at all relevant times, is a resident of Canada for purposes of the Tax Act (a “Resident Holder”).

Interest

A Resident Holder (other than a corporation, partnership, unit trust or any trust of which a corporation or a partnership is a beneficiary) will be required to include in computing its income for a taxation year any interest on a bond that becomes receivable or is received by it before the end of the year (depending upon the method regularly followed by the Resident Holder in computing income), except to the extent that such interest was included in computing the Resident Holder’s income for a preceding taxation year. In addition, if at any time a bond is, or becomes, an “investment contract” (as defined in the Tax Act) in relation to such Resident Holder, the Resident Holder will be required to include in computing its income for a taxation year any interest that accrues

S-20

to the Canadian investor on the bond to the end of any “anniversary day” (as defined in the Tax Act) in that taxation year to the extent such interest was not otherwise included in the Resident Holder’s income for that taxation year or a preceding taxation year.

A Resident Holder that is a corporation, partnership, unit trust or any trust of which a corporation or a partnership is a beneficiary will be required to include in computing its income for a taxation year any interest on a bond that accrues to it to the end of that year, or that becomes receivable or is received by it before the end of the year, except to the extent that such interest was included in computing the Resident Holder’s income for a preceding taxation year.

If the offering price of a bond includes unpaid interest from the issue date to the time of its acquisition by a Resident Holder, the amount of such unpaid interest may be deducted by the Resident Holder in a taxation year to the extent that the amount was included in the Resident Holder’s income for the taxation year, and the amount so deductible will reduce the adjusted cost base of the debt security to the Resident Holder.

Dispositions

A Resident Holder will generally be required to include in computing its income for the taxation year in which a disposition of a bond occurs (or is deemed to occur) the amount of interest that accrues to it to the date of the disposition, except to the extent that such amount has otherwise been included in income.

In general, a disposition or deemed disposition of a bond will give rise to a capital gain (or capital loss) equal to the amount by which the proceeds of disposition, net of any accrued interest and any reasonable costs of disposition, exceed (or are less than) the Resident Holder’s adjusted cost base of such bond immediately before the disposition. One-half of any such capital gain (a “taxable capital gain”) realized by a Resident Holder in a taxation year will be included in computing the Resident Holder’s income for the year. One-half of the amount of any capital loss (an “allowable capital loss”) realized by a Resident Holder in a taxation year must be deducted from taxable capital gains realized by the Resident Holder in the year. Allowable capital losses in excess of taxable capital gains realized in the year may be carried back and deducted against net taxable gains realized in the three preceding taxation years or in any subsequent taxation year, to the extent and under the circumstances described in the Tax Act.

Certain Tax Proposals released on June 10, 2024 (the “Capital Gains Increase Proposals”) will, if enacted in their current form, increase the capital gains inclusion rate for capital gains realized on or after June 25, 2024, from one-half to two-thirds for (i) corporations and trusts, and (ii) individuals on the portion of capital gains realized in a year that exceeds Cdn. $250,000. The Capital Gains Increase Proposals also provide for corresponding adjustments to the inclusion rate of capital losses and capital losses carried forward from prior years (such that a capital loss realized prior to the rate change would fully offset an equivalent capital gain realized after the rate change), as well as for transitional rules and other consequential amendments. Canadian investors should consult their own tax advisers with respect to their particular circumstances.

Additional Refundable Tax

A Resident Holder that is: (i) a “Canadian-controlled private corporation” (as defined in the Tax Act) throughout the year or, (ii) a “substantive CCPC” (as defined in the Tax Act) at any time in the year, may be liable to pay an additional refundable tax on certain investment income, including an amount in respect of interest and taxable capital gains.

Investors Not Resident in Canada

The following section of this summary is applicable to a Holder who, at all relevant times, for the purposes of the Tax Act, is, or is deemed to be, a non-resident of Canada and who does not hold or is not deemed to use or hold the debt securities in carrying on business in Canada (a “Non-Resident Holder”). Special rules, which are not discussed in this summary, may apply to a non-resident that is an insurer carrying on business in Canada and elsewhere. This summary assumes that no amount paid or payable in respect of the bonds will be the deduction

S-21

component of a “hybrid mismatch arrangement” under which the payment arises within the meaning of paragraph 18.4(3)(b) of the Tax Act. In general terms, a payment may be considered to arise under a “hybrid mismatch arrangement” in certain circumstances, including if (i) a payer of the payment does not deal at “arm’s length” with, or is a “specified entity” in respect of, a recipient of the payment, or (ii) the payment arises under, or in connection with, a “structured arrangement” (each within the meaning of the Tax Act), in each case, where certain additional conditions are met. Two entities will generally be treated as specified entities in respect of one another if one entity, directly or indirectly, holds a 25% equity interest in the other entity, or a third entity, directly or indirectly, holds a 25% equity interest in both entities. Prospective investors should note that the rules in the Tax Act relating to hybrid mismatch arrangements are highly complex and there remains significant uncertainly as to their interpretation and application.

Interest paid or credited or deemed to be paid or credited by EDC to a Non-Resident Holder on a bond will be exempt from Canadian non-resident withholding tax and EDC will not be required to deduct or withhold tax from interest or principal paid or credited or deemed to be paid or credited by EDC to the Non-Resident Holder on the bond. Generally, there are no other Canadian income taxes that would be payable by a Non-Resident Holder as a result of holding or disposing of a bond (including for greater certainty, any gain realized by a Non-Resident Holder on a disposition of a bond).

Certain U.S. Federal Income Tax Considerations

The following summary supplements the discussion under “Tax Matters—Certain U.S. Federal Income Tax Considerations” in the accompanying basic prospectus, to which reference is hereby made. The description reflects present law, which is subject to prospective and retroactive changes. The following summary deals only with initial purchasers that beneficially own the bonds, are United States Persons (as defined below) and hold the bonds as capital assets for U.S. federal income tax purposes. It does not deal with the tax considerations relevant to certain holders, such as banks, traders who elect to mark to market, life insurance companies, regulated investment companies, real estate investment trusts, persons holding bonds as a hedge, straddle, conversion or integrated transaction, persons subject to any alternative minimum tax, persons whose functional currency is not the U.S. dollar and certain taxpayers who file applicable financial statements required to recognize income when the associated revenue is reflected on such financial statements. In addition to other qualifications set forth in the accompanying basic prospectus, the following summary does not address any U.S. federal tax consequences other than U.S. federal income tax consequences (such as the estate and gift tax) nor does it address the Medicare tax on net investment income.

Prospective purchasers of bonds should consult their own tax advisors concerning the application of the U.S. federal, state and local tax laws to their particular situations, as well as the application of the tax laws of other jurisdictions.

For purposes of this discussion, “United States Person” means a citizen or resident of the United States, a corporation (including a publicly traded partnership or other person that is treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any political subdivision thereof, an estate the income of which is subject to U.S. federal income taxation regardless of its source or a trust that is either subject to the control of one or more U.S. persons and the primary supervision of a U.S. court or has validly elected to be treated as a U.S. person.

Interest Payments

Interest on a bond received or accrued by holders, including Additional Amounts as defined in the accompanying basic prospectus, if any, and any Canadian income tax withheld, will be taxable to such holder as ordinary interest income at the time it is accrued or is paid, in accordance with such holder’s usual method of accounting for U.S. federal income tax purposes. The bonds are expected to be issued without original issue discount for U.S. federal income tax purposes. If Canadian income tax is withheld, a holder may, subject to certain limitations and holding period and other requirements, be entitled to a foreign tax credit against its U.S. federal income tax liability for any such Canadian withholding taxes or, at the election of such holder, a deduction in respect of the amount so withheld. The rules governing foreign tax credits are complex. United

S-22

States Persons should consult their tax advisors regarding the application of such rules to the particular circumstances of such holder.

Dispositions

A holder’s tax basis in a bond generally will be the purchase price of such bond. Upon the sale, exchange, redemption or other taxable disposition of a bond, a holder generally will recognize gain or loss equal to the difference between the amount realized on the sale, exchange, redemption or other taxable disposition (other than accrued but unpaid interest and Additional Amounts, if any) and the holder’s tax basis in such bond. Gain or loss so recognized will be capital gain or loss. Any such capital gain or loss will be long-term capital gain or loss if the bond has been held for more than one year. Prospective investors should consult their tax advisors regarding the treatment of capital gains (which may be taxed at lower rates than ordinary income tax for certain non-corporate taxpayers including individuals) or losses (the deductibility of which is subject to limitations).

S-23

UNDERWRITING

Subject to the terms and conditions set forth in the Underwriting Agreement dated as of July 24, 2024 (the “Underwriting Agreement”), each of the underwriters named below (the “Underwriters”), for whom BMO Capital Markets Corp., HSBC Bank plc, Scotia Capital (USA) Inc. and Wells Fargo Securities, LLC are acting as representatives (the “Representatives”), has severally agreed to purchase, and EDC has agreed to sell to each of them severally, the respective principal amounts of bonds set forth opposite its name below. Under the terms and conditions of the Underwriting Agreement, the Underwriters are committed to take and pay for all of the bonds, if any are taken. The Underwriters may act through their respective U.S. affiliates or other U.S. broker-dealers when offering any bonds in the United States.

The Underwriters have advised EDC that they propose initially to offer the bonds directly to the public at the initial public offering price set forth on the cover page of this prospectus supplement. After the initial public offering, the public offering price may be changed.

The bonds are offered for sale in the United States, Canada and those jurisdictions in Europe and Asia where it is legal to make such offers.

Purchasers may be required to pay stamp duties or taxes and other charges in accordance with the laws and practices of the country of purchase in addition to the issue price set forth above.

The bonds are a new issue of securities with no established trading market. EDC has been advised by the Representatives that some of the Underwriters intend to make a market in the bonds, but they are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of, or the trading markets for, the bonds.

EDC has agreed to indemnify the several Underwriters against certain liabilities, including liabilities under the U.S. Securities Act of 1933, as amended.

EDC will pay its issuing expenses estimated at U.S. $150,000. EDC’s estimated net proceeds from the issuance of the bonds will be approximately U.S. $998,725,000.

Certain of the Underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with EDC or its affiliates. Certain of the Underwriters and their affiliates have received, or may in the future receive, customary fees and commissions for these transactions.

In addition, in the ordinary course of their business activities, certain of the Underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of EDC or its affiliates. Certain of the Underwriters or their affiliates that have a lending relationship with EDC routinely hedge, and certain other of those Underwriters or their affiliates may hedge, their credit exposure to EDC consistent with their customary risk management policies. Typically, such Underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in EDC securities, including potentially the bonds offered hereby. Any such short positions could adversely affect future trading prices of the bonds offered hereby. Certain of the Underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

S-24

We expect that delivery of the bonds will be made against payment therefor on or about August 1, 2024, which is six business days following the date of pricing of the bonds (this settlement cycle being referred to as “T+6”). Under Rule 15c6-1 of the U.S. Securities Exchange Act, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade their bonds prior to the initial T+6 settlement may be required, by virtue of the fact that the bonds settle on a delayed basis, to specify an alternate settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisers.

Each of the Underwriters has agreed that it has not offered, sold or delivered and it will not offer, sell or deliver, directly or indirectly, any of the bonds or distribute this prospectus supplement, the accompanying basic prospectus or any other offering material relating to the bonds, in or from any jurisdiction except under circumstances that will, to the best of its knowledge and belief, result in compliance with the applicable laws and regulations thereof and which will not impose any obligations on EDC except as contained in the Underwriting Agreement.

In relation to each Member State of the EEA (a “Relevant State”), each Underwriter has represented and agreed that it has not made and will not make an offer of bonds which are the subject of the offering contemplated by this prospectus supplement and the accompanying basic prospectus to the public in that Relevant State other than:

provided that no such offer of bonds shall require EDC or any Underwriter to publish a prospectus pursuant to Article 3 of the Prospectus Regulation or supplement a prospectus pursuant to Article 23 of the Prospectus Regulation. For the purposes of this provision, the expression an “offer of bonds” in relation to any bonds in any Relevant State means the communication in any form and by any means of sufficient information on the terms of the offer and the bonds to be offered so as to enable an investor to decide to purchase or subscribe for the bonds. For greater certainty, EDC’s intention is that EDC’s offer ends with the offer by the Underwriters of the bonds to their customers.

Each Underwriter has represented, warranted and agreed that it has not made and will not make an offer of the bonds to the public in the UK except that it may make an offer of the bonds in the UK:

For the purposes of this provision, the expression “an offer of the bonds to the public” in relation to any bonds in the UK means the communication in any form and by any means of sufficient information on the terms of the offer and the bonds to be offered so as to enable an investor to decide to purchase or subscribe for the bonds. For greater certainty, EDC’s intention is that EDC’s offer ends with the offer by the Underwriters of the bonds to their customers.

EXPORT DEVELOPMENT CANADA

History and Purpose

EDC was established on October 1, 1969, by the Export Development Act, a statute of the Parliament of Canada.

EDC supports and develops, directly or indirectly, Canada’s export trade and Canadian capacity to engage in that trade and to respond to international business opportunities. EDC offers financing, guarantee, insurance, equity, connections and knowledge products and services to Canadian exporters and investors and their international buyers. To the greatest extent possible, EDC operates on a financially self-sustaining basis in accordance with commercial principles.

EDC may also provide support in the domestic market without the requirement for ministerial approval. In line with EDC’s export-related mandate, regulations under the Export Development Act allow EDC to provide domestic support (financing, guarantees and insurance) to companies that have at least 50% of their total annual sales in the export and foreign markets. EDC is required to ensure that its domestic transactions complement those of the Business Development Bank of Canada and private sector institutions.

In March 2020, in response to the COVID-19 pandemic crisis, the Government of Canada suspended certain regulations concerning domestic support and broadened EDC’s mandate to allow EDC, on a temporary basis, to support and develop, directly or indirectly, domestic business in a manner that complements the products and

2

services available from private sector institutions. The Government of Canada also made certain changes to EDC’s Act concerning contingent liability and its authorized capital limits to allow EDC greater financial flexibility.

With this additional flexibility, EDC anticipates bringing enhanced capacity to domestic transactions such as:

In addition, for the purposes of creating the Development Finance Institute of Canada (DFIC) Inc. (“FinDev Canada”), the Government of Canada broadened EDC’s mandate and scope of activity in May 2017 to include providing, directly or indirectly, development financing and other forms of development support in a manner that is consistent with Canada’s international development priorities. FinDev Canada has been established as a wholly-owned subsidiary of EDC.

The Head Office of EDC is located at 150 Slater Street, Ottawa, Ontario, Canada K1A 1K3 (Telephone: (613) 598-2500). Regional Offices are in Brossard, Calgary, Charlottetown, Drummondville, Edmonton, Halifax, Kitchener, Laval, London (Ontario), Mississauga, Moncton, Montréal, Québec City, Regina, Sherbrooke, St. John’s, Toronto, Vancouver, Windsor and Winnipeg. In addition, EDC operates one branch office in Singapore and Foreign Representations in Atlanta, Beijing, Bogotá, Chicago, Dubai, Düsseldorf, Hong Kong, Istanbul, Johannesburg, Lima, London, Mexico City, Mumbai, New Delhi, Rio de Janeiro, San Pedro Garza Garcia, Santiago, São Paulo, Shanghai and Sydney.

Status as a Crown Corporation

EDC is an agent of Her Majesty in right of Canada and is a Crown corporation whose shares shall be held in trust for Her Majesty. Crown corporations are established by the Parliament of Canada for many purposes, including the administering and managing of public services in which business enterprise and public accountability can be combined. EDC is ultimately accountable for the conduct of its affairs to Parliament through the Minister of International Trade.

TRADE UPDATES

Canada and the United States

Canada and the United States are each other’s most important trading partners, reflecting the physical proximity of the two countries and their close economic and financial relationship. In 2021, trade with the United States accounted for 75.0% of the value of Canada’s merchandise exports and 62.2% of the value of Canada’s merchandise imports. According to the United States Census Bureau, trade with Canada accounted for 17.5% of the United States’ exports and 12.5% of its imports in 2021.

At the regional level, the Canada-United States-Mexico Agreement (“CUSMA”) entered into force between Canada, the U.S. and Mexico on July 1, 2020. The CUSMA preserves the essential trade benefits of the North American Free Trade Agreement (“NAFTA”), including existing tariff commitments, and incorporates new and updated provisions that seek to address 21st century trade issues. The three parties continue to collaborate in ensuring the full implementation of commitments under the Agreement, especially through regular engagement in the CUSMA Free Trade Commission and related committees. The CUSMA is also serving to support the management of regional trade issues, including, for example, U.S. duties on Canadian softwood lumber, Canada’s administration of import quotas for U.S. dairy products, and the interpretation of certain rules of origin for automotive goods.

Canada and China

China is Canada’s second-largest trading partner overall and third largest merchandise export market, after the U.S. and the EU-27. In 2021, 4.6% of Canada’s total exports went to China. Canadian merchandise exports to China in 2021 were $28.8 billion, and imports from China were $85.7 billion. The strong rebound in Canadian exports to China in 2021 follows a 16.4% decrease in 2019. As a result, it was only in 2021 that Canada’s exports returned to the level they were at in 2018.

The Canada-China Foreign Investment Protection and Promotion Agreement (FIPA) entered into force in October 2014. It affords investors protections against discriminatory and arbitrary practices, increases transparency, provides investors with certain guaranteed rights of treatment, and includes dispute settlement procedures. To date, no claims have been initiated against Canada under the FIPA’s dispute resolution mechanism. While Canada and China do not have a bilateral free trade agreement, both are members of the World Trade Organization (WTO). When trade irritants arise, Canada’s approach with China, as with other trading partners, is to try to resolve them through bilateral consultations. If this approach is not successful, Canada may then resort to exercising its rights under the WTO. While Canadian exports to China have increased, there have been a number of trade irritants in the relationship, particularly for agriculture/agri-food exports and air services. As an example, when China blocked shipments of canola seed from two Canadian companies in 2019 citing the discovery of pests in shipments as the grounds for their actions, Canada sought to resolve the issue through technical consultations. When it became apparent that this issue could not be resolved through technical consultations, Canada requested a WTO panel, which has since been established to adjudicate the trade dispute.

USE OF PROCEEDS

The net proceeds of the debt securities to which this prospectus relates will be used for general corporate purposes unless otherwise stated in an applicable prospectus supplement.

DESCRIPTION OF THE DEBT SECURITIES

The following is a brief summary of the terms and conditions of the debt securities and the fiscal agency agreement under which the debt securities will be issued. Copies of the forms of debt securities and the form of fiscal agency agreement are or will be filed or incorporated by reference as exhibits to the registration statement of which this prospectus is a part. This summary does not purport to be complete and is qualified in its entirety by reference to such exhibits and to any applicable prospectus supplement. You should read the form of fiscal agency agreement, the forms of debt securities and any applicable prospectus supplement before making your investment decision.

The debt securities may be issued in one or more series as may be authorized from time to time by EDC. Reference is made to the applicable prospectus supplement for the following terms of debt securities offered thereby: (i) the designation, aggregate principal amount, any limitation on such principal amount and authorized denominations; (ii) the percentage of their principal amount at which such debt securities will be issued; (iii) the maturity date or dates; (iv) the interest rate, if any, which rate may be fixed, variable or floating; (v) the dates and paying agencies when and where interest payments, if any, will be made; (vi) any optional or mandatory redemption terms or repurchase or sinking fund provisions; (vii) whether such debt securities will be in bearer form with interest coupons, if any, or in registered form, or both, and restrictions on the exchange of one form for another, (viii) the currency in which the principal of and interest, if any, on the debt securities will be payable; (ix) any terms for conversions; (x) the exchange or exchanges, if any, on which application for listing of the debt securities may be made; and (xi) other specific provisions.

There will be a fiscal agent or agents for EDC in connection with the debt securities whose duties with respect to any series will be governed by the fiscal agency agreement applicable to such series. EDC may appoint

4

different fiscal agents for different series of debt securities and may vary or terminate the appointment of any fiscal agent from time to time. EDC may maintain deposit accounts and conduct other banking and financial transactions with the fiscal agent. The fiscal agent is the agent of EDC, is not a trustee for the holders of debt securities, and does not have the same responsibilities or duties to act for such holders as would a trustee.

References to principal and interest in respect of the debt securities shall be deemed also to refer to any Additional Amounts which may be payable. See “Payment of Additional Amounts”.

Status

The debt securities will constitute direct unconditional obligations of EDC and as such will carry the full faith and credit of Canada and will constitute direct unconditional obligations of and by Canada. Payments of the principal of and interest, if any, on the debt securities will constitute a charge on and be payable out of the Consolidated Revenue Fund of Canada. The obligations of EDC under each debt security will rank equally with all of EDC’s other unsecured and unsubordinated indebtedness and obligations from time to time outstanding.

Payment of Additional Amounts

All payments of, or in respect of, principal of and interest on the debt securities will be made without withholding of or deduction for, or on account of, any present or future taxes, duties, assessments or charges of whatsoever nature imposed or levied by or on behalf of the Government of Canada, or any province or political subdivision thereof, or any authority thereof or agency therein having power to tax, unless such taxes, duties, assessments or charges are required by law or by the administration or interpretation thereof to be withheld or deducted. In that event, unless otherwise provided in an applicable prospectus supplement, EDC (subject to its rights of redemption) will pay to the registered holders of the debt securities such additional amounts (the “Additional Amounts”) as will result (after withholding or deduction of the said taxes, duties, assessments or charges) in the payment to the holders of debt securities of the amounts which would otherwise have been payable in respect of the debt securities in the absence of such taxes, duties, assessments or charges, except that no such Additional Amounts shall be payable with respect to any debt security:

5

Global Securities

The debt securities may be issued in the form of one or more fully registered global debt securities. The specific terms of the depositary arrangement with respect to any series of debt securities to be issued in the form of a global debt security will be described in the prospectus supplement relating to such series.

Governing Law and Enforceability

The debt securities and the fiscal agency agreement will provide that they are to be governed by, and interpreted in accordance with, the laws of the Province of Ontario and the laws of Canada applicable therein, except as otherwise specified in the prospectus supplement.

No applicable law requires the consent of any public official or authority for proceedings to be brought in Canada or judgment to be obtained in any such proceedings against EDC or Canada arising out of or relating to obligations under the debt securities, nor is any immunity from jurisdiction available to EDC or Canada in any such proceedings, irrespective of whether a party to the proceedings or the holder of the debt security is or is not a resident within or a citizen of Canada. A judgment obtained in an action brought against Her Majesty in right of Canada in the Federal Court of Canada is not capable of being enforced by execution but is payable out of the Consolidated Revenue Fund of Canada. Pursuant to the Currency Act (Canada), a judgment by a court in Canada must be awarded in Canadian currency, and such judgment may be based on a rate of exchange in existence on a day other than the day of payment.

Neither EDC nor Canada has agreed to waive any immunity from jurisdiction or has appointed an agent in the United States upon which process may be served for any purpose. In the absence of a waiver of immunity by EDC or Canada, it would be possible to obtain a United States judgment in an action against EDC or Canada, as the case may be, only if a court were to determine that the United States Foreign Sovereign Immunities Act of 1976 precludes the granting of sovereign immunity. However, even if a United States judgment could be obtained in any such action under that Act, it may not be possible to obtain in Canada a judgment based on such a United States judgment. Moreover, execution upon property of EDC or Canada located in the United States to enforce a judgment obtained under that Act may not be possible except under the limited circumstances specified in that Act.

TAX MATTERS

Canadian Federal Income Tax Consequences

The following constitutes a summary of the principal Canadian federal income tax consequences for an investor who acquires debt securities pursuant to an offering by EDC, is the beneficial owner of the debt securities, at all times for the purposes of the Income Tax Act (Canada) (the “Tax Act”) holds the debt securities as capital property within the meaning of the Tax Act, and deals at arm’s length with EDC and any prospective purchaser of the debt securities.

Generally the debt securities will be considered to be capital property to an investor provided that the investor does not hold the debt securities in the course of carrying on a business of buying and selling securities and has not acquired them as part of an adventure or concern in the nature of trade. This summary does not apply to a financial institution (as defined in Section 142.2(1) of the Tax Act), an investor an interest in which is a “tax shelter investment” (as defined in the Tax Act), or an investor who has elected to report its “Canadian tax results” (as defined in the Tax Act) in a currency other than the Canadian currency.

This summary is based upon the provisions of the Tax Act, the regulations thereunder and the Canada Revenue Agency’s (the “CRA”) published administrative and assessing policies as of the date of this prospectus. It also takes into account specific proposals to amend the Tax Act and the regulations thereunder publicly announced by the Canadian federal Minister of Finance prior to the date of this prospectus, but there is no certainty that such proposals will be enacted in the form proposed, if at all. This summary does not otherwise

6

take into account or anticipate any changes in law, whether by way of legislative, judicial or governmental action or interpretation, nor does it address any provincial or foreign income tax considerations. This summary discusses the tax considerations applicable to persons who purchase debt securities upon their initial offering and does not discuss the tax considerations applicable to subsequent purchasers of the debt securities. The discussion does not address debt securities issued with original issue discount or other special features. The prospectus supplement or pricing supplement applicable to an issue of debt securities with such special features will address the federal income tax considerations relevant to investing in such debt securities and the discussion below is subject to any discussion of federal income tax considerations in an applicable prospectus supplement or pricing supplement.

In general, for the purpose of the Tax Act, all amounts not otherwise expressed in Canadian dollars must be converted into Canadian dollars based on the daily exchange rate as quoted by the Bank of Canada for the applicable day or such other rate of exchange that is acceptable to the CRA.

THIS SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, NOR SHOULD IT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY PARTICULAR INVESTOR CONCERNING THE CONSEQUENCES OF ACQUIRING, HOLDING OR DISPOSING OF DEBT SECURITIES. INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS.

Investors Resident in Canada

The following section of this summary is applicable to an investor holding debt securities who, at all relevant times, is a resident of Canada for purposes of the Tax Act (a “Canadian investor”).

Interest

A Canadian investor (other than a corporation, partnership, unit trust or any trust of which a corporation or a partnership is a beneficiary) will be required to include in computing its income for a taxation year any interest on debt securities that becomes receivable or is received by it before the end of the year (depending upon the method regularly followed by the Canadian investor in computing income), except to the extent that such interest was included in computing the Canadian investor’s income for a preceding taxation year. In addition, if at any time a debt security is, or becomes, an “investment contract” (as defined in the Tax Act) in relation to such Canadian investor, the Canadian investor will be required to include in computing its income for a taxation year any interest that accrues to the Canadian investor on the debt security to the end of any “anniversary day” (as defined in the Tax Act) in that taxation year to the extent such interest was not otherwise included in the Canadian investor’s income for that taxation year or a preceding taxation year.

A Canadian investor that is a corporation, partnership, unit trust or any trust of which a corporation or a partnership is a beneficiary will be required to include in computing its income for a taxation year any interest on debt securities that accrues to it to the end of that year, or that becomes receivable or is received by it before the end of the year, except to the extent that such interest was included in computing the Canadian investor’s income for a preceding taxation year.

If the offering price of a debt security includes unpaid interest from the issue date to the time of its acquisition by a Canadian investor, the amount of such unpaid interest may be deducted by the Canadian investor in a taxation year to the extent that the amount was included in the Canadian investor’s income for the taxation year, and the amount so deductible will reduce the adjusted cost base of the debt security to the Canadian investor.

Dispositions

A Canadian investor will generally be required to include in computing its income for the taxation year in which a disposition of a debt security occurs (or is deemed to occur) the amount of interest that accrues to it to the date of the disposition, except to the extent that such amount has otherwise been included in income.

7

In general, a disposition or deemed disposition of a debt security will give rise to a capital gain (or capital loss) equal to the amount by which the proceeds of disposition, net of any accrued interest and any reasonable costs of disposition, exceed (or are less than) the Canadian investor’s adjusted cost base of such debt security immediately before the disposition. One-half of any such capital gain (a “taxable capital gain”) realized by a Canadian investor in a taxation year will be included in computing the Canadian investor’s income for the year. One-half of the amount of any capital loss (an “allowable capital loss”) realized by a Canadian investor in a taxation year must be deducted from taxable capital gains realized by the Canadian investor in the year. Allowable capital losses in excess of taxable capital gains realized in the year may be carried back and deducted against net taxable gains realized in the three preceding taxation years or in any subsequent taxation year, to the extent and under the circumstances described in the Tax Act.

Additional Refundable Tax

A Canadian investor that is throughout the year a “Canadian-controlled private corporation” (as defined in the Tax Act) may be liable to pay an additional refundable tax on certain investment income, including an amount in respect of interest and taxable capital gains.

Investors Not Resident in Canada

The following section of this summary is applicable to an investor holding debt securities who, at all relevant times, for the purposes of the Tax Act, is, or is deemed to be, a non-resident of Canada and who does not hold or is not deemed to use or hold the debt securities in, or in the course of, carrying on a business in Canada (a “non-resident investor”). Special rules, which are not discussed in this summary, may apply to a non-resident that is an insurer carrying on business in Canada and elsewhere.

A non-resident investor will not be subject to Canadian non-resident withholding tax on any interest paid or credited on the debt securities, provided that none of the interest (other than on a “prescribed obligation” described below) so payable is contingent or dependent on the use of, or production from, property in Canada or is computed by reference to revenue, profit, cash flow, commodity price or any other similar criterion or by reference to dividends paid or payable to shareholders of any class or series of shares of the capital stock of a corporation. A “prescribed obligation” is a debt obligation the terms or conditions of which provide for an adjustment to an amount payable in respect of the obligation for a period during which the obligation was outstanding which adjustment is determined by reference to a change in the purchasing power of money and no amount payable in respect thereof, other than an amount determined by reference to a change in the purchasing power of money, is contingent or dependent upon, or computed by reference to, any of the criteria described in the preceding sentence.

If applicable, the normal rate of Canadian non-resident withholding tax is 25% but such rate may be reduced under the terms of an applicable income tax treaty.

No other Canadian taxes on income, including taxable capital gains on the disposition of a debt security, are payable by a non-resident investor in respect of a debt security.

Certain U.S. Federal Income Tax Considerations

The following is a summary of certain material U.S. federal income tax considerations relating to the purchase, ownership and disposition of the debt securities by U.S. Holders (as defined below), but does not purport to be a complete analysis of all of the potential tax considerations. This summary is based on the provisions of the Code, applicable Treasury Regulations promulgated or proposed thereunder, judicial authority and current administrative rulings and practice, all of which are subject to change, possibly on a retroactive basis. This summary addresses only investors that will hold the debt securities as “capital assets”, and does not address tax considerations applicable to investors that are subject to special tax rules including those applicable to banks, tax-exempt organizations, insurance companies, dealers, traders in securities or other persons who are required or who elect to mark to market, persons that will hold debt securities as a position in a hedging, straddle, conversion

8

or integrated transaction, persons that have a functional currency other than the U.S. dollar and certain taxpayers who file applicable financial statements required to recognize income when the associated revenue is reflected on such financial statements. This summary discusses the tax considerations applicable to persons who purchase debt securities from the underwriters upon their initial offering and does not discuss the tax considerations applicable to subsequent purchasers of the debt securities. The discussion does not address debt securities issued in bearer form or with original issue discount or other special features (such as floating rate debt securities, short-term debt securities or debt securities that are subject to the rules for contingent payment debt instruments) or warrants to purchase debt securities. The prospectus supplement applicable to an issue of debt securities with such special features will address the U.S. federal income tax considerations relevant to your investment in such debt securities and the discussion below is subject to any discussion of U.S. federal income tax considerations in an applicable pricing supplement. If a partnership holds a debt security, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership or a partner of a partnership holding a debt security, you should consult your own tax advisor. This summary does not address any U.S. federal tax consequences other than U.S. federal income tax consequences (such as the estate and gift tax or the Medicare tax on net investment income). This summary does not cover any State or local or foreign tax implications of the acquisition, ownership, or disposition of the debt securities.

WE ENCOURAGE YOU TO CONSULT YOUR OWN TAX ADVISOR WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL TAX LAWS TO YOUR PARTICULAR SITUATION AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

As used herein, the term “U.S. Holder” means the beneficial owner of a debt security that for U.S. federal income tax purposes is (i) a citizen or individual resident of the United States, (ii) a corporation created or organized in the United States or under the laws of the United States or of any State or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of source, or (iv) a trust if a court within the United States is able to exercise primary supervision over the trust’s administration and one or more U.S. persons have authority to control all of the trust’s substantial decisions (or for certain trusts formed prior to August 20, 1996, if such trust has a valid election in effect under U.S. law to be treated as a U.S. person).

Interest Payments

The term “interest” as used in this section “Certain U.S. Federal Income Tax Considerations” includes any Additional Amounts required to be paid under the terms of a debt security. Interest on a debt security that you receive or accrue (whether received in U.S. dollars or a currency other than the U.S. dollar (“foreign currency”)) will be taxable to you as ordinary interest income at the time it is accrued or paid, in accordance with your method of accounting for U.S. federal income tax purposes. Interest received or accrued by you on a debt security generally will be income from sources outside the United States for purposes of computing the foreign tax credit limitation. For foreign tax credit limitation purposes, the income will generally be “passive category income” or, in the case of certain U.S. Holders, “general category income”. The rules regarding the availability of foreign tax credits are complex and your ability to credit foreign taxes may be subject to various limitations. You should discuss the foreign tax credit rules with your own tax advisor. If you are a cash basis taxpayer and you receive an interest payment in foreign currency, you will be required to include in income the U.S. dollar value of such payment determined on the date such payment is received, regardless of whether the payment is in fact converted to U.S. dollars at that time.

If you are an accrual basis holder of a debt security denominated in a foreign currency, you will be required to include in income the U.S. dollar value of the amount of interest income that has accrued with respect to an interest accrual period, determined by translating such income at the average rate of exchange for the relevant interest accrual period or, with respect to an interest accrual period that spans two taxable years, at the average rate for the portion of such interest accrual period within the taxable year. The average rate of exchange for an interest accrual period (or portion thereof) is the simple average of the spot exchange rates for each business day of such period (or such other average that is reasonably derived and consistently applied). You may elect to translate interest income on debt securities denominated in a foreign currency using the exchange rate on the last

9

day of an interest accrual period (or the last day of the taxable year for the portion of such period within the taxable year). In addition, you may elect to use the exchange rate on the date of receipt for such purpose if such date is within five business days of the last date of an interest accrual period. The election must be made in a statement filed with your return, and is applicable to all debt instruments for such year and thereafter unless changed with the consent of the Internal Revenue Service (the “IRS”).

Upon receipt of an interest payment (whether in a foreign currency or U.S. dollars), if you are an accrual basis taxpayer, you will recognize ordinary income or loss with respect to accrued interest income in an amount equal to the difference between the U.S. dollar value of the payment received (determined on the date such payment is received) in respect of such interest accrual period and the U.S. dollar value of the interest income that you accrued during such interest accrual period (as determined in the preceding paragraph). Any such income or loss generally will not be treated as interest income or expense, except to the extent provided by administrative pronouncements of the IRS.

Dispositions

Your tax basis in a debt security generally will be the U.S. dollar value of your purchase price of such debt security on the date of purchase. Upon the sale, exchange, retirement or redemption of a debt security, you generally will recognize gain or loss equal to the difference between the amount realized on the sale, exchange, retirement or redemption (or the U.S. dollar value of the amount if it is realized in a foreign currency) and your tax basis in such debt security. Except with respect to gains or losses attributable to changes in exchange rates, as described in the next paragraph, gain or loss so recognized will be capital gain or loss. Any such capital gain or loss will be long-term capital gain or loss if the debt has been held for more than one year. You should consult your tax advisor regarding the treatment of capital gains (which may be taxed at lower rates than ordinary income for certain taxpayers) or losses (the deductibility of which is subject to limitations).

Gain or loss attributable to changes in exchange rates with respect to the amount received in respect of or the principal amount of a debt security generally will equal the difference, if any, between the U.S. dollar value of your foreign currency purchase price for the debt security determined at the spot rate on the date you dispose of the debt security and the U.S. dollar value of your foreign currency purchase price for the debt security determined at the spot rate on the date you purchased such debt security. In addition, upon the sale, exchange, retirement or redemption of a debt security, you may realize exchange gain or loss attributable to amounts received with respect to accrued and unpaid interest, which will be treated as discussed above under “Interest Payments”.

Such foreign currency gain or loss is recognized on the sale, exchange, retirement or redemption of a debt security only to the extent of total gain or loss recognized on the sale, exchange, retirement or redemption of such debt security. Gain or loss recognized on the sale, exchange, retirement or redemption of a debt security that is attributable to changes in the rate of exchange between the U.S. dollar and a foreign currency generally will be treated as ordinary income or loss and generally will be U.S. source gain or loss for purposes of computing the foreign tax credit limitation.

Transactions in Foreign Currency

Foreign currency received as a payment of interest on, or on the sale, exchange, retirement or redemption of, a debt security will have a tax basis equal to its U.S. dollar value at the time such interest is received or at the time payment is received in consideration of such sale, exchange, retirement or redemption. The amount of gain or loss recognized on a sale or other disposition of such foreign currency will be equal to the difference between (i) the amount of U.S. dollars, or the fair market value in U.S. dollars of the other currency or property received in such sale or other disposition, and (ii) the tax basis of the recipient in such foreign currency and will be ordinary gain or loss.

Backup Withholding and Information Reporting

In general, payments of interest on, and the proceeds of a sale, redemption or other disposition of, a debt security, payable to you by a U.S. paying agent or other U.S. intermediary will be reported to the IRS and to you

10

as required under applicable regulations. Backup withholding may apply to these payments if you fail to provide an accurate taxpayer identification number or certification of exempt status or fail to report all interest and dividends required to be shown on your U.S. federal income tax return. Certain U.S. Holders (including, among others, corporations) are not subject to backup withholding. You should consult your tax advisor as to your qualification for exemption from backup withholding and the procedure for obtaining an exemption. Backup withholding may be refunded or allowed as a credit against your U.S. federal income tax liabilities if the required information is timely furnished to the IRS.

Certain U.S. holders that own “specified foreign financial assets” with an aggregate value in excess of U.S.$50,000 are generally required to file an information statement along with their tax returns, currently on Form 8938, with respect to such assets. “Specified foreign financial assets” include any financial accounts held at a non-U.S. financial institution, as well as securities issued by a non-U.S. issuer that are not held in accounts maintained by financial institutions Investors who fail to report required information may be subject to substantial penalties. You should consult your tax advisor regarding this and other reporting obligations relating to an investment in the debt securities.
