[424B2] BARCLAYS BANK PLC Prospectus Supplement

Rhea-AI Filing Summary

Barclays Bank PLC launched a preliminary pricing supplement for Market Linked Securities—Auto-Callable with Contingent Downside due November 4, 2030, linked to the lowest performing of the Dow Jones Industrial Average, Russell 2000, and S&P 500.

Each security has a $1,000 principal amount, original offering price of $1,000, agent discount of $28.25, and proceeds to the issuer of $971.75 per security. The notes may be automatically called on scheduled dates if the lowest performing index is at or above its 90% call level, paying the principal plus a call premium that steps up at least ~7.20% per annum (e.g., at least $1,072.00 on Nov 4, 2026, up to at least $1,360.00 on Oct 30, 2030). Investors do not participate in index upside beyond the fixed call premiums.

If not called, at maturity holders receive $1,000 if the lowest performing index is at or above its 75% threshold level; otherwise, repayment equals $1,000 times the index performance factor, exposing principal to losses that can reach zero. The securities are unsecured, unsubordinated obligations of Barclays Bank PLC and are subject to the U.K. Bail‑in Power. Pricing date is October 30, 2025; issue date is November 4, 2025.

The information in this preliminary pricing supplement is not complete and may be changed. This preliminary pricing supplement and the accompanying prospectus, prospectus supplement, product supplement and underlying supplement do not constitute an offer to sell the securities and we are not soliciting an offer to buy the securities in any state where the offer or sale is not permitted.

Global Medium-Term Notes, Series A

Market Linked Securities—Auto-Callable with Contingent Downside

Principal at Risk Securities Linked to the Lowest Performing of the Dow Jones Industrial Average^®, the Russell 2000^® Index and the S&P 500^® Index due November 4, 2030

n  Linked to the lowest performing of the Dow Jones Industrial Average^®, the Russell 2000^® Index and the S&P 500^® Index (each referred to as an “Index”)

n  Unlike ordinary debt securities, the securities do not pay interest, do not repay a fixed amount of principal at stated maturity and are subject to potential automatic call upon the terms described below. Whether the securities are automatically called for a fixed call premium and, if the securities are not automatically called, whether you are repaid the principal amount of your securities at stated maturity will depend in each case on the closing level of the lowest performing Index on the relevant call date. The lowest performing Index on any call date is the Index that has the lowest performance factor on that call date, calculated for each Index as the closing level of that Index on that call date divided by its starting level.

n  Automatic Call. If the closing level of the lowest performing Index on any call date (occurring quarterly, beginning after approximately one year and ending at stated maturity) is greater than or equal to its call level, the securities will be automatically called for the principal amount plus the call premium applicable to the relevant call date. The call premium applicable to each call date will be a percentage of the principal amount that increases for each call date based on a simple (non-compounding) return of at least approximately 7.20% per annum (to be determined on the pricing date). Please see “Terms of the Securities—Call Dates and Call Premiums” below for the call dates and call premiums.

n  Potential Loss of Principal. If the securities are not automatically called, you will receive the principal amount at stated maturity if the closing level of the lowest performing Index on the final calculation day is greater than or equal to its threshold level. If the closing level of the lowest performing Index on the final calculation day is less than its threshold level, you will lose more than 25%, and possibly all, of the principal amount of your securities.

n  The call level of each Index is equal to 90% of its starting level.

n  The threshold level of each Index is equal to 75% of its starting level.

n  Any positive return on the securities will be limited to the applicable call premium, even if the closing level of the lowest performing Index on the applicable call date significantly exceeds its starting level. You will not participate in any appreciation of any Index.

n  Your return on the securities will depend solely on the performance of the Index that is the lowest performing Index on each call date. You will not benefit in any way from the performance of the better performing Indices. Therefore, you will be adversely affected if any Index performs poorly, even if the other Indices perform favorably.

n  Any payment on the securities, including any repayment of principal, is subject to the creditworthiness of Barclays Bank PLC and is not guaranteed by any third party. If Barclays Bank PLC were to default on its payment obligations or become subject to the exercise of any U.K. Bail-in Power (as described on page PPS-7 of this pricing supplement) by the relevant U.K. resolution authority, you might not receive any amounts owed to you under the securities. See “Selected Risk Considerations” and “Consent to U.K. Bail-in Power” in this pricing supplement and “Risk Factors” in the accompanying prospectus supplement.

n  No periodic interest payments or dividends

n  No exchange listing; designed to be held to maturity

See “Additional Information about the Issuer and the Securities” on page PPS-5 of this pricing supplement. The securities will have the terms specified in the prospectus dated May 15, 2025, the prospectus supplement dated May 15, 2025, the product supplement no. WF-1 dated May 20, 2025 and the underlying supplement dated May 15, 2025, as supplemented or superseded by this pricing supplement.

The securities have complex features and investing in the securities involves risks not associated with an investment in conventional debt securities. See “Selected Risk Considerations” on page PPS-11 herein, “Risk Factors” beginning on page PS-3 of the product supplement and “Risk Factors” beginning on page S-9 of the prospectus supplement.

The securities constitute our unsecured and unsubordinated obligations. The securities are not deposit liabilities of Barclays Bank PLC and are not covered by the U.K. Financial Services Compensation Scheme or insured by the U.S. Federal Deposit Insurance Corporation or any other governmental agency or deposit insurance agency of the United States, the United Kingdom or any other jurisdiction.

Neither the U.S. Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of these securities or determined that this pricing supplement is truthful or complete. Any representation to the contrary is a criminal offense.

Notwithstanding and to the exclusion of any other term of the securities or any other agreements, arrangements or understandings between Barclays Bank PLC and any holder or beneficial owner of the securities (or the trustee on behalf of the holders of the securities), by acquiring the securities, each holder or beneficial owner of the securities acknowledges, accepts, agrees to be bound by, and consents to the exercise of, any U.K. Bail-in Power by the relevant U.K. resolution authority.

Principal at Risk Securities Linked to the Lowest Performing of the Dow Jones Industrial Average^®, the Russell 2000^® Index and the S&P 500^® Index due November 4, 2030

Additional Information Regarding Our Estimated Value of the Securities 

The final terms for the securities will be determined on the date the securities are initially priced for sale to the public (the “pricing date”) based on prevailing market conditions on or prior to the pricing date and will be communicated to investors orally and/or in a final pricing supplement.

Our internal pricing models take into account a number of variables and are based on a number of subjective assumptions, which may or may not materialize, typically including volatility, interest rates and our internal funding rates. Our internal funding rates (which are our internally published borrowing rates based on variables, such as market benchmarks, our appetite for borrowing and our existing obligations coming to maturity) may vary from the levels at which our benchmark debt securities trade in the secondary market. Our estimated value on the pricing date is based on our internal funding rates. Our estimated value of the securities might be lower if such valuation were based on the levels at which our benchmark debt securities trade in the secondary market.

Our estimated value of the securities on the pricing date is expected to be less than the original offering price of the securities. The difference between the original offering price of the securities and our estimated value of the securities is expected to result from several factors, including any sales commissions expected to be paid to Barclays Capital Inc. or another affiliate of ours, any selling concessions, discounts, commissions or fees expected to be allowed or paid to non-affiliated intermediaries, the estimated profit that we or any of our affiliates expect to earn in connection with structuring the securities, the estimated cost that we may incur in hedging our obligations under the securities, and estimated development and other costs that we may incur in connection with the securities.

Our estimated value on the pricing date is not a prediction of the price at which the securities may trade in the secondary market, nor will it be the price at which Barclays Capital Inc. may buy or sell the securities in the secondary market. Subject to normal market and funding conditions, Barclays Capital Inc. or another affiliate of ours intends to offer to purchase the securities in the secondary market but it is not obligated to do so.

Assuming that all relevant factors remain constant after the pricing date, the price at which Barclays Capital Inc. may initially buy or sell the securities in the secondary market, if any, and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed our estimated value on the pricing date for a temporary period expected to be approximately five months after the initial issue date of the securities because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the securities and other costs in connection with the securities that we will no longer expect to incur over the term of the securities. We made such discretionary election and determined this temporary reimbursement period on the basis of a number of factors, which may include the tenor of the securities and/or any agreement we may have with the distributors of the securities. The amount of our estimated costs that we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the initial issue date of the securities based on changes in market conditions and other factors that cannot be predicted.

We urge you to read the “Selected Risk Considerations” beginning on page PPS-11 of this pricing supplement.

You may revoke your offer to purchase the securities at any time prior to the pricing date. We reserve the right to change the terms of, or reject any offer to purchase, the securities prior to their pricing date. In the event of any changes to the terms of the securities, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes in which case we may reject your offer to purchase.

Consent to U.K. Bail-in Power 

Notwithstanding and to the exclusion of any other term of the securities or any other agreements, arrangements or understandings between us and any holder or beneficial owner of the securities (or the trustee on behalf of the holders of the securities), by acquiring the securities, each holder or beneficial owner of the securities acknowledges, accepts, agrees to be bound by and consents to the exercise of, any U.K. Bail-in Power by the relevant U.K. resolution authority.

Under the U.K. Banking Act 2009, as amended, the relevant U.K. resolution authority may exercise a U.K. Bail-in Power in circumstances in which the relevant U.K. resolution authority is satisfied that the resolution conditions are met. These conditions include that a U.K. bank or investment firm is failing or is likely to fail to satisfy the Financial Services and Markets Act 2000 (the “FSMA”) threshold conditions for authorization to carry on certain regulated activities (within the meaning of section 55B FSMA) or, in the case of a U.K. banking group company that is a European Economic Area (“EEA”) or third country institution or investment firm, that the relevant EEA or third country relevant authority is satisfied that the resolution conditions are met in respect of that entity.

The U.K. Bail-in Power includes any write-down, conversion, transfer, modification and/or suspension power, which allows for (i) the reduction or cancellation of all, or a portion, of the principal amount of, or interest on, or any other amounts payable on, the securities; (ii) the conversion of all, or a portion, of the principal amount of, or interest on, or any other amounts payable on, the securities into shares or other securities or other obligations of Barclays Bank PLC or another person (and the issue to, or conferral on, the holder or beneficial owner of the securities of such shares, securities or obligations); (iii) the cancellation of the securities and/or (iv) the amendment or alteration of the maturity of the securities, or the amendment of the amount of interest or any other amounts due on the securities, or the dates on which interest or any other amounts become payable, including by suspending payment for a temporary period; which U.K. Bail-in Power may be exercised by means of a variation of the terms of the securities solely to give effect to the exercise by the relevant U.K. resolution authority of such U.K. Bail-in Power. Each holder and beneficial owner of the securities further acknowledges and agrees that the rights of the holders or beneficial owners of the securities are subject to, and will be varied, if necessary, solely to give effect to, the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority. For the avoidance of doubt, this consent and acknowledgment is not a waiver of any rights holders or beneficial owners of the securities may have at law if and to the extent that any U.K. Bail-in Power is exercised by the relevant U.K. resolution authority in breach of laws applicable in England.

For more information, please see “Selected Risk Considerations—Risks Relating to the Issuer—You May Lose Some or All of Your Investment If Any U.K. Bail-in Power Is Exercised by the Relevant U.K. Resolution Authority” in this pricing supplement as well as “U.K. Bail-in Power,” “Risk Factors—Risks Relating to the Securities Generally—Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail, including the exercise by the relevant U.K. resolution authority of a variety of statutory resolution powers, could materially adversely affect the value of any securities” and “Risk Factors—Risks Relating to the Securities Generally—Under the terms of the securities, you have agreed to be bound by the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority” in the accompanying prospectus supplement.

Investor Considerations 

The securities are not appropriate for all investors. The securities may be an appropriate investment for you if all of the following statements are true:

· You do not seek an investment that produces periodic interest or coupon payments or other sources of current income.

· You anticipate that the closing level of the lowest performing Index will be greater than or equal to its call level on one of the call dates.

· You do not anticipate that the ending level of the lowest performing Index on the final calculation day will be less than its threshold level, and you are willing and able to accept the risk that, if it is, you will lose more than 25%, and possibly all, of the principal amount of your securities at stated maturity.

· You are willing and able to accept the individual market risk of each Index and you understand that poor performance by any Index over the term of the securities may negatively affect your return and will not be offset or mitigated by any positive performance by the other Indices.

· You are willing and able to forgo participation in any appreciation of any Index, and you understand that any return on your investment will be limited to any call premium that may be payable on the securities.

· You are willing and able to accept the risks associated with an investment linked to the performance of the lowest performing Index, as explained in more detail in the “Selected Risk Considerations” section of this pricing supplement.

· You understand and accept that you will not be entitled to receive dividends or distributions that may be paid to holders of the securities composing the Indices, nor will you have any voting rights with respect to the securities composing the Indices.

· You are willing and able to accept the risk that the securities may be automatically called prior to stated maturity and that you may not be able to reinvest your money in an alternative investment with comparable risk and yield.

· You do not seek an investment for which there will be an active secondary market and you are willing and able to hold the securities to stated maturity if the securities are not automatically called.

· You are willing and able to assume our credit risk for all payments on the securities.

· You are willing and able to consent to the exercise of any U.K. Bail-in Power by any relevant U.K. resolution authority.

The securities may not be an appropriate investment for you if any of the following statements are true:

· You seek an investment that produces periodic interest or coupon payments or other sources of current income.

· You seek an investment that provides for the full repayment of principal at stated maturity.

· You anticipate that the closing level of the lowest performing Index will be less than its call level on each call date.

· You anticipate that the ending level of the lowest performing Index on the final calculation day will be less than its threshold level, or you are unwilling or unable to accept the risk that, if it is, you will lose more than 25%, and possibly all, of the principal amount of your securities at stated maturity.

· You are unwilling or unable to accept the individual market risk of each Index or the risk that poor performance by any Index over the term of the securities may negatively affect your return and will not be offset or mitigated by any positive performance by the other Indices.

· You seek exposure to any upside performance of the Indices or you seek an investment with a return that is not limited to any call premium that may be payable on the securities.

· You are unwilling or unable to accept the risks associated with an investment linked to the performance of the lowest performing Index, as explained in more detail in the “Selected Risk Considerations” section of this pricing supplement.

· You seek an investment that entitles you to dividends or distributions on, or voting rights related to, the securities composing the Indices.

· You are unwilling or unable to accept the risk that the securities may be automatically called prior to stated maturity and that you may not be able to reinvest your money in an alternative investment with comparable risk and yield.

· You seek an investment for which there will be an active secondary market and/or you are unwilling or unable to hold the securities to stated maturity if they are not automatically called.

· You are unwilling or unable to assume our credit risk for all payments on the securities.

· You are unwilling or unable to consent to the exercise of any U.K. Bail-in Power by any relevant U.K. resolution authority.

The considerations identified above are not exhaustive. Whether or not the securities are an appropriate investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the appropriateness of an investment in the securities in light of your particular circumstances. You should also review carefully the “Selected Risk Considerations” beginning on page PPS-11 of this pricing supplement and the “Risk Factors” beginning on page PS-3 of the accompanying product supplement and the “Risk Factors” beginning on page S-9 of the accompanying prospectus supplement for risks related to an investment in the securities.

Determining Payment on a Call Settlement Date and at Maturity 

On each call settlement date, whether the securities are automatically called and whether you receive a call premium will each be determined based on the closing level of the lowest performing Index on the related call date.

Step 1: Determine which Index is the lowest performing Index on the relevant call date. The lowest performing Index on any call date is the Index that has the lowest performance factor on that call date, calculated for each Index as the closing level of that Index on that call date divided by its starting level.

Step 2: Determine if the securities are automatically called and whether a call premium is paid on the applicable call settlement date, based on the closing level of the lowest performing Index on the relevant call date, as follows:

On the stated maturity date, if the securities have not been automatically called, you will receive a cash payment per security calculated as described below.

Step 1: Determine which Index is the lowest performing Index on the final calculation day. The lowest performing Index on the final calculation day is the Index that has the lowest performance factor on the final calculation day, calculated for each Index as its ending level divided by its starting level.

Step 2: Calculate the maturity payment amount based on the ending level of the lowest performing Index on the final calculation day, as follows:

Selected Risk Considerations 

An investment in the securities involves significant risks. Investing in the securities is not equivalent to investing directly in any or all of the Indices or their components. Some of the risks that apply to an investment in the securities are summarized below, but we urge you to read the more detailed explanation of risks relating to the securities generally in the “Risk Factors” sections of the product supplement and prospectus supplement. You should not purchase the securities unless you understand and can bear the risks of investing in the securities.

Risks Relating to the Securities Generally

· If The Securities Are Not Automatically Called, You May Lose Some Or All Of The Principal Amount Of Your Securities At Stated Maturity — We will not repay you a fixed amount on your securities at stated maturity. If the securities are not automatically called, you will receive a maturity payment amount that will be equal to or less than the principal amount, depending on the ending level of the lowest performing Index on the final calculation day.

If the ending level of the lowest performing Index on the final calculation day is less than its threshold level, the maturity payment amount will be less than the principal amount and you will have full downside exposure to the decrease in the level of the lowest performing Index from its starting level. The threshold level for each Index is 75% of its starting level. For example, if the securities are not automatically called and the lowest performing Index on the final calculation day has declined by 25.1% from its starting level to its ending level, you will not receive any benefit of the contingent downside protection feature and you will lose 25.1% of the principal amount. As a result, you will not receive any protection if the level of the lowest performing Index on the final calculation day declines significantly and you may lose some, and possibly all, of the principal amount of your securities at stated maturity, even if the level of the lowest performing Index is greater than or equal to its call level or its threshold level at certain times during the term of the securities.

· Your Return Will Be Limited To The Applicable Call Premium And May Be Lower Than The Return On A Direct Investment In The Securities Composing Any Or All Of The Indices — You will not participate in the possible increases in the level of the lowest performing Index through an investment in the securities. Any positive return on the securities will not exceed the applicable call premium, regardless of any increase in the level of the lowest performing Index, which may be significant. Furthermore, if the securities are called on an earlier call date, you will receive a lower call premium than if the securities were called on a later call date, and accordingly, if the securities are called on one of the earlier call dates, you will not receive the highest potential call premium.

· No Periodic Interest Will Be Paid On The Securities — No periodic payments of interest will be made on the securities.

· The Securities Are Subject To The Full Risks Of Each Index And Will Be Negatively Affected If Any Index Performs Poorly, Even If The Other Indices Perform Favorably — You are subject to the full risks of each Index. If any Index performs poorly, you will be negatively affected, even if the other Indices perform favorably. The securities are not linked to a basket composed of the Indices, where the better performance of some Indices could offset the poor performance of others. Instead, you are subject to the full risks of whichever Index is the lowest performing Index on each call date. As a result, the securities are riskier than an alternative investment linked to only one of the Indices or linked to a basket composed of each Index. You should not invest in the securities unless you understand and are willing to accept the full downside risks of each Index.

· You May Be Fully Exposed To The Decline In The Lowest Performing Index On The Final Calculation Day From Its Starting Level, But Will Not Participate In Any Positive Performance Of Any Index — Even though you will be fully exposed to a decline in the level of the lowest performing Index on the final calculation day if the securities are not automatically called and the ending level of the lowest performing Index on the final calculation day is below its threshold level, you will not participate in any increase in the level of any Index over the term of the securities. Your maximum possible return on the securities will be limited to any call premium you may receive. Consequently, your return on the securities may be significantly less than the return you could achieve on an alternative investment that provides for participation in an increase in the level of any or each Index.

· Your Return On The Securities Will Depend Solely On The Performance Of The Index That Is The Lowest Performing Index On Each Call Date, And You Will Not Benefit In Any Way From The Performance Of The Better Performing Indices — Your return on the securities will depend solely on the performance of the Index that is the lowest performing Index on each call date. Although it is necessary for each Index to close at or above its respective call level on the relevant call date in order for you to receive a call premium or, if the securities are not called, at or above its respective threshold level on the final calculation day in order for you to be repaid the principal amount of your securities at maturity, you will not benefit in any way from the performance of the better performing Indices. The securities may underperform an alternative investment linked to a basket composed of the Indices, since in such case the performance of the better performing Indices would be blended with the performance of the lowest performing Index, resulting in a better return than the return of the lowest performing Index alone.

Principal at Risk Securities Linked to the Lowest Performing of the Dow Jones Industrial Average^®, the Russell 2000^® Index and the S&P 500^® Index due November 4, 2030

· Higher Call Premium Rates Are Associated With Greater Risk — The securities offer call premiums at a higher rate, if paid, than the fixed rate we would pay on conventional debt securities of the same maturity. These higher potential call premiums are associated with greater levels of expected risk as of the pricing date as compared to conventional debt securities, including the risk that you may not receive a call premium on any call settlement date and the risk that you may lose a substantial portion, and possibly all, of the principal amount at maturity. The volatility of the Indices and the correlation among the Indices are important factors affecting this risk. Volatility is a measure of the degree of variation in the levels of the Indices over a period of time. Volatility can be measured in a variety of ways, including on a historical basis or on an expected basis as implied by option prices in the market. The correlation of a pair of Indices represents a statistical measurement of the degree to which the returns of those Indices are similar to each other over a given period in terms of timing and direction. Greater expected volatility of the Indices or lower expected correlation among the Indices as of the pricing date may result in higher call premiums, but it also represents a greater expected likelihood as of the pricing date that the closing level of at least one Index will be less than its call level on each call date, such that you will not receive any call premium during the term of the securities, and that the closing level of at least one Index will be less than its threshold level on the final calculation day such that you will lose a substantial portion, and possibly all, of the principal amount at maturity. In general, the higher the call premiums are relative to the fixed rate we would pay on conventional debt securities, the greater the expected risk that you will not receive any call premium during the term of the securities and that you will lose a substantial portion, and possibly all, of the principal amount at maturity.

· You Will Be Subject To Reinvestment Risk — If your securities are automatically called, the term of the securities may be reduced to as short as approximately one year. There is no guarantee that you would be able to reinvest the proceeds from an investment in the securities at a comparable return for a similar level of risk in the event the securities are automatically called prior to maturity.

· You Will Be Subject To Risks Resulting From The Relationship Between The Indices — The correlation of a pair of Indices represents a statistical measurement of the degree to which the returns of those Indices are similar to each other over a given period in terms of timing and direction. By investing in the securities, you assume the risk that the returns of the Indices will not be correlated. The less correlated the Indices, the more likely it is that any one of the Indices will be performing poorly at any time over the term of the securities. All that is necessary for the securities to perform poorly is for one of the Indices to perform poorly; the performance of the better performing Indices is not relevant to your return on the securities. It is impossible to predict what the relationship between the Indices will be over the term of the securities. The Indices may represent different equity markets, and those equity markets may not perform similarly over the term of the securities.

· Any Payment On The Securities Will Be Determined Based On The Closing Levels Of The Indices On The Dates Specified — Any payment on the securities will be determined based on the closing levels of the Indices on the dates specified. You will not benefit from any more favorable values of the Indices determined at any other time.

· Owning The Securities Is Not The Same As Owning The Securities Composing Any Or All Of The Indices — The return on your securities may not reflect the return you would realize if you actually owned the securities composing any or all of the Indices. For instance, as a holder of the securities, you will not have voting rights or rights to receive cash dividends or other distributions or any other rights that holders of the securities composing any Index would have.

· No Assurance That The Investment View Implicit In The Securities Will Be Successful — It is impossible to predict whether and the extent to which the level of any Index will rise or fall. There can be no assurance that the level of any Index will not close below its call level on each call date or, if the securities are not called, below its threshold level on the final calculation day. The level of each Index will be influenced by complex and interrelated political, economic, financial and other factors that affect that Index and the securities composing that Index. You should be willing to accept the downside risks associated with equities in general and each Index in particular, and the risk of losing a significant portion or all of the principal amount.

· The U.S. Federal Income Tax Consequences Of An Investment In The Securities Are Uncertain — There is no direct legal authority regarding the proper U.S. federal income tax treatment of the securities, and we do not plan to request a ruling from the Internal Revenue Service (the “IRS”). Consequently, significant aspects of the tax treatment of the securities are uncertain, and the IRS or a court might not agree with the treatment of the securities as prepaid forward contracts, as described below under “Tax Considerations.” If the IRS were successful in asserting an alternative treatment for the securities, the tax consequences of the ownership and disposition of the securities could be materially and adversely affected.

In addition, in 2007 the Treasury Department and the IRS released a notice requesting comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. Any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect. You should review carefully the sections of the accompanying prospectus supplement entitled “Material U.S. Federal Income Tax Consequences—Tax Consequences to U.S. Holders—Notes Treated as Prepaid Forward Contracts” and, if you are a non-U.S. holder, “—Tax Consequences to Non-U.S. Holders,” and consult your tax advisor regarding the U.S. federal tax consequences of an investment in the securities (including possible alternative treatments and the issues presented by the 2007 notice), as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Risks Relating to the Issuer

· The Securities Are Subject To The Credit Risk Of Barclays Bank PLC — The securities are unsecured and unsubordinated debt obligations of the issuer, Barclays Bank PLC, and are not, either directly or indirectly, an obligation of any third party. Any payment to be made on the securities, including any repayment of principal, is subject to the ability of Barclays Bank PLC to satisfy its obligations as they come due and is not guaranteed by any third party. As a result, the actual and perceived creditworthiness of Barclays Bank PLC may affect the market value of the securities and, in the event Barclays Bank PLC were to default on its obligations, you might not receive any amount owed to you under the terms of the securities.

· You May Lose Some Or All Of Your Investment If Any U.K. Bail-In Power Is Exercised By The Relevant U.K. Resolution Authority — Notwithstanding and to the exclusion of any other term of the securities or any other agreements, arrangements or understandings between Barclays Bank PLC and any holder or beneficial owner of the securities (or the trustee on behalf of the holders of the securities), by acquiring the securities, each holder or beneficial owner of the securities acknowledges, accepts, agrees to be bound by, and consents to the exercise of, any U.K. Bail-in Power by the relevant U.K. resolution authority as set forth under “Consent to U.K. Bail-in Power” in this pricing supplement. Accordingly, any U.K. Bail-in Power may be exercised in such a manner as to result in you and other holders and beneficial owners of the securities losing all or a part of the value of your investment in the securities or receiving a different security from the securities, which may be worth significantly less than the securities and which may have significantly fewer protections than those typically afforded to debt securities. Moreover, the relevant U.K. resolution authority may exercise the U.K. Bail-in Power without providing any advance notice to, or requiring the consent of, the holders and beneficial owners of the securities. The exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the securities will not be a default or an Event of Default (as each term is defined in the senior debt securities indenture) and the trustee will not be liable for any action that the trustee takes, or abstains from taking, in either case, in accordance with the exercise of the U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the securities. See “Consent to U.K. Bail-in Power” in this pricing supplement as well as “U.K. Bail-in Power,” “Risk Factors—Risks Relating to the Securities Generally—Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail, including the exercise by the relevant U.K. resolution authority of a variety of statutory resolution powers, could materially adversely affect the value of any securities” and “Risk Factors—Risks Relating to the Securities Generally—Under the terms of the securities, you have agreed to be bound by the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority” in the accompanying prospectus supplement.

Risks Relating to the Indices

· The Securities Are Subject To Small-Capitalization Companies Risk With Respect To The RTY Index — The RTY Index tracks companies that are considered small-capitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies, and therefore securities linked to the RTY Index may be more volatile than an investment linked to an index with component stocks issued by large-capitalization companies. Stock prices of small-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business and economic developments. In addition, small-capitalization companies are typically less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Small-capitalization companies are often subject to less analyst coverage and may be in early, and less predictable, periods of their corporate existences. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products.

· Each Index Reflects The Price Return Of The Securities Composing That Index, Not The Total Return — The return on the securities is based on the performance of the Indices, which reflects changes in the market prices of the securities composing each Index. Each Index is not a “total return” index that, in addition to reflecting those price returns, would also reflect dividends paid on the securities composing the applicable Index. Accordingly, the return on the securities will not include such a total return feature.

· We Cannot Control Actions Of Any Of The Unaffiliated Companies Whose Securities Are Included As Components Of The Indices — Actions by any company whose securities are components of an Index may have an adverse effect on the price of its security, the closing level of such Index on any call date, the ending level of such Index and the value of the securities. These unaffiliated companies will not be involved in the offering of the securities and will have no obligations with respect to the securities, including any obligation to take our or your interests into consideration for any reason. These companies will not receive any of the proceeds of the offering of the securities and will not be responsible for, and will not have participated in, the determination of the timing of, prices for, or quantities of, the securities to be issued. These companies will not be involved with the administration, marketing or trading of the securities and will have no obligations with respect to any amounts to be paid to you on the securities.

· We And Our Affiliates Have No Affiliation With Any Index Sponsor And Have Not Independently Verified Their Public Disclosure Of Information — We, our affiliates and WFS and its affiliates are not affiliated in any way with any index sponsor and have no ability to control or predict their actions, including any errors in or discontinuation of disclosure regarding the methods or policies relating to the calculation of the applicable Index. We have derived the information about each Index contained in this pricing supplement and the accompanying underlying supplement from publicly available information, without independent verification. You, as an investor in the securities, should make your own investigation into each Index and the index sponsors. The

Market Linked Securities—Auto-Callable with Contingent Downside

index sponsors will not be involved in the offering of the securities made hereby in any way, and the index sponsors do not have any obligation to consider your interests as an owner of the securities in taking any actions that might affect the value of the securities.

· Adjustments To The Indices Could Adversely Affect The Value Of The Securities And The Amount You Will Receive At Maturity — The sponsor of an Index (an “index sponsor”) may add, delete, substitute or adjust the securities composing that Index or make other methodological changes to that Index that could affect its performance. The calculation agent will calculate the value to be used as the closing level of an Index in the event of certain material changes in or modifications to that Index. In addition, an index sponsor may also discontinue or suspend calculation or publication of that Index at any time. Under these circumstances, the calculation agent may select a successor index that the calculation agent determines to be comparable to the discontinued index or, if no successor index is available, the calculation agent will determine the value to be used as the closing level of that Index. Any of these actions could adversely affect the level of the relevant Index and, consequently, the value of the securities. See “General Terms of the Securities—Certain Terms for Securities Linked to an Index—Adjustments to an Index” and “—Discontinuance of an Index” in the accompanying product supplement.

· The Historical Performance Of The Indices Is Not An Indication Of Their Future Performance — The historical performance of the Indices should not be taken as an indication of the future performance of the Indices. It is impossible to predict whether the closing levels of the Indices will fall or rise during the term of the securities, in particular in the environment in the last several years, which has been characterized by volatility across a wide range of asset classes. Past fluctuations and trends in the levels of the Indices are not necessarily indicative of fluctuations or trends that may occur in the future.

Risks Relating to Conflicts of Interest

· Potentially Inconsistent Research, Opinions Or Recommendations By Barclays Capital Inc., WFS Or Their Respective Affiliates — Barclays Capital Inc., WFS or their respective affiliates may publish research from time to time on financial markets and other matters that may influence the value of the securities or express opinions or provide recommendations that are inconsistent with purchasing or holding the securities. Any research, opinions or recommendations expressed by Barclays Capital Inc., WFA or their respective affiliates may not be consistent with each other and may be modified from time to time without notice. You should make your own independent investigation of each Index and the merits of investing in the securities.

· We, Our Affiliates And Any Other Agent And/Or Participating Dealer May Engage In Various Activities Or Make Determinations That Could Materially Affect Your Securities In Various Ways And Create Conflicts Of Interest — We, our affiliates, WFS and any dealer participating in the distribution of the securities (a “participating dealer”) may play a variety of roles in connection with the issuance of the securities, as described below. In performing these roles, our economic interests and the economic interests of our affiliates, WFS and any participating dealer are potentially adverse to your interests as an investor in the securities.

In connection with our normal business activities and in connection with hedging our obligations under the securities, we and our affiliates make markets in and trade various financial instruments or products for our accounts and for the account of our clients and otherwise provide investment banking and other financial services with respect to these financial instruments and products. These financial instruments and products may include securities, derivative instruments or assets that may relate to the Indices or their components. In any such market making, trading and hedging activity, investment banking and other financial services, we or our affiliates may take positions or take actions that are inconsistent with, or adverse to, the investment objectives of the holders of the securities. We and our affiliates have no obligation to take the needs of any buyer, seller or holder of the securities into account in conducting these activities. Such market making, trading and hedging activity, investment banking and other financial services may negatively impact the value of the securities. Participating dealers may also engage in such activities that may negatively impact the value of the securities.

In addition, the role played by Barclays Capital Inc., as the agent for the securities, could present significant conflicts of interest with the role of Barclays Bank PLC, as issuer of the securities. For example, Barclays Capital Inc. or its representatives may derive compensation or financial benefit from the distribution of the securities and such compensation or financial benefit may serve as an incentive to sell the securities instead of other investments. Furthermore, we and our affiliates establish the offering price of the securities for initial sale to the public, and the offering price is not based upon any independent verification or valuation.

Furthermore, if any dealer participating in the distribution of the securities or any of its affiliates conducts hedging activities for us in connection with the securities, that participating dealer or its affiliates will expect to realize a projected profit from such hedging activities, and this projected profit will be in addition to any selling concession and/or any fee that the participating dealer realizes for the sale of the securities to you. This additional projected profit may create a further incentive for the participating dealer to sell the securities to you.

In addition to the activities described above, Barclays Bank PLC will also act as the calculation agent for the securities. As calculation agent, we will determine any levels of the Indices and make any other determinations necessary to calculate any payments on the securities. In making these determinations, we may be required to make discretionary judgments, including those described in the accompanying product supplement and under “—Risks Relating to the Indices” above. In making these discretionary judgments, our economic interests are potentially adverse to your interests as an investor in the securities, and any of these determinations may adversely affect any payments on the securities. Absent manifest error, all determinations of the calculation agent will be final and

binding, without any liability on the part of the calculation agent. You will not be entitled to any compensation from Barclays Bank PLC for any loss suffered as a result of any determinations made by the calculation agent with respect to the securities.

Risks Relating to the Estimated Value of the Securities and the Secondary Market

· The Securities Will Not Be Listed On Any Securities Exchange And We Do Not Expect A Trading Market For The Securities To Develop — The securities will not be listed on any securities exchange. Barclays Capital Inc. and other affiliates of Barclays Bank PLC intend to make a secondary market for the securities but are not required to do so, and may discontinue any such secondary market making at any time, without notice. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. Because other dealers are not likely to make a secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which Barclays Capital Inc. and other affiliates of Barclays Bank PLC are willing to buy the securities. The securities are not designed to be short-term trading instruments. Accordingly, you should be willing and able to hold your securities to maturity.

· The Value Of The Securities Prior To Maturity Will Be Affected By Numerous Factors, Some Of Which Are Related In Complex Ways — Structured notes, including the securities, can be thought of as securities that combine a debt instrument with one or more options or other derivative instruments. As a result, the factors that influence the values of debt instruments and options or other derivative instruments will also influence the terms and features of the securities at issuance and their value in the secondary market. Accordingly, in addition to the levels of the Indices on any day, the value of the securities will be affected by a number of economic and market factors that may either offset or magnify each other, including:

· the expected volatility of the Indices;

· correlation (or lack of correlation) of the Indices;

· the time to maturity of the securities;

· the market prices of, and dividend rates on, the securities composing the Indices;

· interest and yield rates in the market generally;

· supply and demand for the securities;

· a variety of economic, financial, political, regulatory and judicial events; and

· our creditworthiness, including actual or anticipated downgrades in our credit ratings.

· The Estimated Value Of Your Securities Is Expected To Be Lower Than The Original Offering Price Of Your Securities — The estimated value of your securities on the pricing date is expected to be lower, and may be significantly lower, than the original offering price of your securities. The difference between the original offering price of your securities and the estimated value of the securities is expected as a result of certain factors, such as any sales commissions, selling concessions, discounts, commissions or fees expected to be allowed or paid to Barclays Capital Inc., another affiliate of ours, WFS or its affiliates or other non-affiliated intermediaries, the estimated profit that we or any of our affiliates expect to earn in connection with structuring the securities, the estimated cost that we may incur in hedging our obligations under the securities, and estimated development and other costs that we may incur in connection with the securities.

· The Estimated Value Of Your Securities Might Be Lower If Such Estimated Value Were Based On The Levels At Which Our Debt Securities Trade In The Secondary Market — The estimated value of your securities on the pricing date is based on a number of variables, including our internal funding rates. Our internal funding rates may vary from the levels at which our benchmark debt securities trade in the secondary market. As a result of this difference, the estimated values referenced above might be lower if such estimated values were based on the levels at which our benchmark debt securities trade in the secondary market.

· The Estimated Value Of The Securities Is Based On Our Internal Pricing Models, Which May Prove To Be Inaccurate And May Be Different From The Pricing Models Of Other Financial Institutions — The estimated value of your securities on the pricing date is based on our internal pricing models, which take into account a number of variables and are based on a number of subjective assumptions, which may or may not materialize. These variables and assumptions are not evaluated or verified on an independent basis. Further, our pricing models may be different from other financial institutions’ pricing models and the methodologies used by us to estimate the value of the securities may not be consistent with those of other financial institutions that may be purchasers or sellers of securities in the secondary market. As a result, the secondary market price of your securities may be materially different from the estimated value of the securities determined by reference to our internal pricing models.

· The Estimated Value Of Your Securities Is Not A Prediction Of The Prices At Which You May Sell Your Securities In The Secondary Market, If Any, And Such Secondary Market Prices, If Any, Will Likely Be Lower Than The Original Offering Price Of Your Securities And May Be Lower Than The Estimated Value Of Your Securities — The estimated value of the securities will not be a prediction of the prices at which Barclays Capital Inc., other affiliates of ours or third parties may be willing to purchase the securities from you in secondary market transactions (if they are willing to purchase, which they are not obligated to do). The price at which you may be able to sell your securities in the secondary market at any time will be influenced by many factors that cannot be predicted, such as market conditions, and any bid and ask spread for similar sized trades, and may be substantially less than our estimated value of the securities. Further, as secondary market prices of your securities take into account the levels at which our debt securities trade in the secondary market, and do not take into account our various costs related to the securities such as fees, commissions, discounts, and the costs of hedging our obligations under the securities, secondary market prices of your securities will likely be lower than the original offering price of your securities.

Hypothetical Examples and Returns 

The payout profile, return tables and examples below illustrate hypothetical payments upon an automatic call or at stated maturity for a $1,000 principal amount security on a hypothetical offering of securities under various scenarios, with the assumptions set forth in the table below. Terms used for purposes of these hypothetical examples do not represent the actual starting level, call level, threshold level or ending level of any Index. The actual amount you receive at stated maturity or upon automatic call will depend on the actual terms of the securities. You should not take these examples as an indication or assurance of the expected performance of the securities. These examples are for purposes of illustration only. The values used in the examples may have been rounded for ease of analysis. The examples below do not take into account any tax consequences from investing in the securities.

Hypothetical Call Premiums:	Call Date	Call Premium*
	1st call date	7.20% of the principal amount
	2nd call date	9.00% of the principal amount
	3rd call date	10.80% of the principal amount
	4th call date	12.60% of the principal amount
	5th call date	14.40% of the principal amount
	6th call date	16.20% of the principal amount

	*Based on the minimum values specified for the call premiums
Hypothetical Starting Level:	For each Index, 100.00
Hypothetical Call Level:	For each Index, 90.00 (90% of its hypothetical starting level)
Hypothetical Threshold Level:	For each Index, 75.00 (75% of its hypothetical starting level)

The hypothetical starting level of 100.00 for each Index has been chosen for illustrative purposes only and does not represent the actual starting level for any Index. The actual starting level, call level and threshold level for each Index will be determined on the pricing date and will be set forth under “Terms of the Securities” above. For historical closing levels of the Indices, see the historical information set forth under the sections titled “The Dow Jones Industrial Average^®,” “The Russell 2000^® Index” and “The S&P 500^® Index” below. We cannot predict the closing level of the Index on any day during the term of the securities, including on any call date.

If the securities are not automatically called:

If the securities are not automatically called, the following table illustrates, for a range of hypothetical performance factors of the lowest performing Index on the final calculation day, the hypothetical maturity payment amount payable at stated maturity per security. The performance factor of the lowest performing Index on the final calculation day is calculated as its ending level divided by its starting level.

Hypothetical performance factor of lowest performing Index on final calculation day	Hypothetical maturity payment amount per security
89.99%	$1,000.00
85.00%	$1,000.00
75.00%	$1,000.00
74.99%	$749.90
70.00%	$700.00
60.00%	$600.00
50.00%	$500.00
40.00%	$400.00
30.00%	$300.00
20.00%	$200.00
10.00%	$100.00
0.00%	$0.00

Hypothetical Examples of Payment upon an Automatic Call or at Stated Maturity

Example 1. The closing level of the lowest performing Index on the first call date is greater than or equal to its call level. As a result, the securities are automatically called on the first call date.

	INDU Index	RTY Index	SPX Index
Hypothetical starting level:	100.00	100.000	100.00
Hypothetical closing level on first call date:	150.00	140.000	130.00
Hypothetical call level:	90.00	90.000	90.00
Performance factor on first call date (closing level on first call date divided by starting level):	150.00%	140.00%	130.00%

Step 1: Determine which Index is the lowest performing Index on the first call date.

In this example, the SPX Index has the lowest performance factor on the first call date and is, therefore, the lowest performing Index on the first call date.

Step 2: Determine the payment upon automatic call.

Because the hypothetical closing level of the lowest performing Index on the first call date is greater than or equal to its hypothetical call level, the securities are automatically called on the first call date and you will receive on the related call settlement date the principal amount of your securities plus a call premium of 7.20% of the principal amount. Even though the lowest performing Index appreciated by 30.00% from its starting level to its closing level on the first call date in this example, your return is limited to the call premium of 7.20% that is applicable to that call date.

On the call settlement date, you would receive $1,072.00 per security.

Example 2. The securities are not automatically called prior to the last call date (the final calculation day). The closing level of the lowest performing Index on the final calculation day is greater than or equal to its call level. As a result, the securities are automatically called on the final calculation day.

	INDU Index	RTY Index	SPX Index
Hypothetical starting level:	100.00	100.000	100.00
Hypothetical closing level on call dates prior to the final calculation day:	Various (at least one Index below call level)
Hypothetical closing level on final calculation day:	105.00	110.000	125.00
Hypothetical call level:	90.00	90.000	90.00
Performance factor on final calculation day (ending level divided by starting level):	105.00%	110.00%	125.00%

Step 1: Determine which Index is the lowest performing Index on the final calculation day.

In this example, the INDU Index has the lowest performance factor on the final calculation day and is, therefore, the lowest performing Index on the final calculation day.

Step 2: Determine the payment upon automatic call.

Because the hypothetical closing level of the lowest performing Index on each call date prior to the last call date (which is the final calculation day) is less than its hypothetical call level, the securities are not automatically called prior to the final calculation day. Because the hypothetical closing level of the lowest performing Index on the final calculation day is greater than or equal to its call level, the securities are automatically called on the final calculation day and you will receive on the related call settlement date (which is the stated maturity date) the principal amount of your securities plus a call premium of 36.00% of the principal amount.

On the call settlement date (which is the stated maturity date), you would receive $1,360.00 per security.

Example 3. The securities are not automatically called prior to maturity. The ending level of the lowest performing Index on the final calculation day is less than its call level but greater than or equal to its threshold level, and the maturity payment amount is equal to the principal amount of your securities at maturity.

	INDU Index	RTY Index	SPX Index
Hypothetical starting level:	100.00	100.000	100.00
Hypothetical closing level on call dates prior to the final calculation day:	Various (at least one Index below call level)
Hypothetical ending level:	115.00	85.000	110.00
Hypothetical call level:	90.00	90.000	90.00
Hypothetical threshold level:	75.00	75.000	75.00
Performance factor on final calculation day (ending level divided by starting level):	115.00%	85.00%	110.00%

Step 1: Determine which Index is the lowest performing Index on the final calculation day.

In this example, the RTY Index has the lowest performance factor and is, therefore, the lowest performing Index on the final calculation day.

Step 2: Determine the maturity payment amount based on the ending level of the lowest performing Index on the final calculation day.

Because the hypothetical closing level of the lowest performing Index on each call date (including the final calculation day) is less than its hypothetical call level, the securities are not automatically called. Since the hypothetical ending level of the lowest performing Index on the final calculation day is not less than its hypothetical threshold level, you would be repaid the principal amount of your securities at maturity.

On the stated maturity date, you would receive $1,000.00 per security.

Principal at Risk Securities Linked to the Lowest Performing of the Dow Jones Industrial Average^®, the Russell 2000^® Index and the S&P 500^® Index due November 4, 2030

Example 4. The securities are not automatically called prior to maturity. The ending level of the lowest performing Index on the final calculation day is less than its threshold level, and the maturity payment amount is less than the principal amount of your securities at maturity.

	INDU Index	RTY Index	SPX Index
Hypothetical starting level:	100.00	100.000	100.00
Hypothetical closing level on call dates prior to the final calculation day:	Various (at least one Index below call level)
Hypothetical ending level:	45.00	120.000	90.00
Hypothetical call level:	90.00	90.000	90.00
Hypothetical threshold level:	75.00	75.000	75.00
Performance factor on final calculation day (ending level divided by starting level):	45.00%	120.00%	90.00%

Step 1: Determine which Index is the lowest performing Index on the final calculation day.

In this example, the INDU Index has the lowest performance factor and is, therefore, the lowest performing Index on the final calculation day.

Step 2: Determine the maturity payment amount based on the ending level of the lowest performing Index on the final calculation day.

Because the hypothetical closing level of the lowest performing Index on each call date (including the final calculation day) is less than its hypothetical call level, the securities are not automatically called. Since the hypothetical ending level of the lowest performing Index on the final calculation day is less than its hypothetical threshold level, you would lose a portion of the principal amount of your securities and receive the maturity payment amount equal to $450.00 per security, calculated as follows:

$1,000 × performance factor of the lowest performing Index on the final calculation day

= $1,000 × 45.00%

= $450.00

On the stated maturity date, you would receive $450.00 per security. This example illustrates that you will be fully exposed to a decrease in the lowest performing Index if the ending level of the lowest performing Index on the final calculation day is less than its threshold level, even if the ending levels of the other Indices have appreciated or have not declined below their respective threshold levels.

Tax Considerations

You should review carefully the sections in the accompanying prospectus supplement entitled “Material U.S. Federal Income Tax Consequences—Tax Consequences to U.S. Holders—Notes Treated as Prepaid Forward Contracts” and, if you are a non-U.S. holder, “—Tax Consequences to Non-U.S. Holders.” The following discussion, when read in combination with those sections, constitutes the full opinion of our special tax counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the securities.

Based on current market conditions, in the opinion of our special tax counsel, it is reasonable to treat the securities for U.S. federal income tax purposes as prepaid forward contracts with respect to the Indices. Assuming this treatment is respected, if you are a U.S. holder, upon a sale or exchange of the securities (including redemption upon an automatic call or at maturity), you should recognize capital gain or loss equal to the difference between the amount realized on the sale or exchange and your tax basis in the securities, which should equal the amount you paid to acquire the securities. This gain or loss on your securities should be treated as long-term capital gain or loss if you hold your securities for more than a year, whether or not you are an initial purchaser of the securities at the original issue price. The deductibility of capital losses is subject to limitations. However, the IRS or a court may not respect this treatment, in which case the timing and character of any income or loss on the securities could be materially and adversely affected. In addition, in 2007 the U.S. Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; the relevance of factors such as the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose a notional interest charge. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect. You should consult your tax advisor regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments and the issues presented by this notice.

Treasury regulations under Section 871(m) generally impose a withholding tax on certain “dividend equivalents” under certain “equity linked instruments.” A recent IRS notice excludes from the scope of Section 871(m) instruments issued prior to January 1, 2027 that do not have a “delta of one” with respect to underlying securities that could pay U.S.-source dividends for U.S. federal income tax purposes (each an “Underlying Security”). Based on our representation that the securities do not have a “delta of one” within the meaning of the regulations, our special tax counsel believes that these regulations should not apply to the securities with regard to non-U.S. holders, and we have determined to treat the securities as not being subject to Section 871(m). Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security. If necessary, further information regarding the potential application of Section 871(m) will be provided in the pricing supplement for the securities. You should consult your tax advisor regarding the potential application of Section 871(m) to the securities.

Non-U.S. holders should also discuss with their tax advisors the estate tax consequences of investing in the securities.
