CONSENT TO U.K. BAIL-IN POWER

Notwithstanding any other agreements, arrangements or understandings between us and any holder or beneficial owner of the Notes, by acquiring the Notes, each holder and beneficial owner of the Notes 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, interest on, or any other amounts payable on, the Notes; (ii) the conversion of all, or a portion, of the principal amount of, interest on, or any other amounts payable on, the Notes 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 Notes such shares, securities or obligations); and/or (iii) the amendment or alteration of the maturity of the Notes, or amendment of the amount of interest or any other amounts due on the Notes, 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 Notes 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 Notes further acknowledges and agrees that the rights of the holders or beneficial owners of the Notes 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 Notes 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—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 could materially adversely affect the value of the 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.

ADDITIONAL INFORMATION REGARDING OUR ESTIMATED VALUE OF THE NOTES

The range of the estimated values of the Notes referenced above may not correlate on a linear basis with the range of any other term of the Notes as may be set forth in this pricing supplement. We determined the size of such range based on prevailing market conditions, as well as the anticipated duration of the marketing period for the Notes. The final terms for the Notes will be determined on the date the Notes are initially priced for sale to the public, which we refer to as the Initial Valuation Date, based on prevailing market conditions on or prior to the Initial Valuation Date, and will be communicated to investors either orally 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 Initial Valuation Date is based on our internal funding rates. Our estimated value of the Notes may 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 Notes on the Initial Valuation Date is expected to be less than the initial issue price of the Notes. The difference between the initial issue price of the Notes and our estimated value of the Notes 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 Notes, the estimated cost which we may incur in hedging our obligations under the Notes, and estimated development and other costs which we may incur in connection with the Notes.

Our estimated value on the Initial Valuation Date is not a prediction of the price at which the Notes may trade in the secondary market, nor will it be the price at which Barclays Capital Inc. may buy or sell the Notes 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 Notes in the secondary market but it is not obligated to do so.

Assuming that all relevant factors remain constant after the Initial Valuation Date, the price at which Barclays Capital Inc. may initially buy or sell the Notes 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 Initial Valuation Date for a temporary period expected to be approximately six months after the Issue Date because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the Notes and other costs in connection with the Notes which we will no longer expect to incur over the term of the Notes. 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 Notes and/or any agreement we may have with the distributors of the Notes. The amount of our estimated costs which 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 Notes 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 PS–6 of this pricing supplement.

You may revoke your offer to purchase the Notes at any time prior to the Initial Valuation Date. We reserve the right to change the terms of, or reject any offer to purchase, the Notes prior to the Initial Valuation Date. In the event of any changes to the terms of the Notes, 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.

HYPOTHETICAL EXAMPLES OF AMOUNTS PAYABLE AT MATURITY

The following table illustrates the hypothetical payment at maturity under various circumstances. The “total return” as used in these examples is the number, expressed as a percentage, that results from comparing the payment at maturity per $1,000 principal amount Note to $1,000. The examples set forth below are purely hypothetical and are provided for illustrative purposes only and may not be the actual total returns applicable to a purchaser of the Notes. The numbers appearing in the following table and examples have been rounded for ease of analysis. The hypothetical examples below do not take into account any tax consequences from investing in the Notes and make the following key assumption:

§Hypothetical Initial Value: 100.00*

*The hypothetical Initial Value of 100.00 has been chosen for illustrative purposes only and does not represent a likely Initial Value. The actual Initial Value will be equal to the Closing Value of the Reference Asset on the Initial Valuation Date.

For information regarding recent values of the Reference Asset, please see “Information Regarding the Reference Asset” in this pricing supplement.

Final Value	Reference Asset Return	Payment at Maturity**	Total Return on Notes
150.00	50.00%	$1,565.00	56.50%

0.00	-100.00%	$900.00	-10.00%

**per $1,000 principal amount Note

The following examples illustrate how the total returns set forth in the table above are calculated:

Example 1: The value of the Reference Asset increases from an Initial Value of 100.00 to a Final Value of 110.00.

Because the Reference Asset Return is greater than or equal to 0.00%, you will receive a payment at maturity of $1,113.00 per $1,000 principal amount Note that you hold, calculated as follows:

$1,000 + [$1,000 × Reference Asset Return × Upside Leverage Factor]

$1,000 + [$1,000 × 10.00% × 1.13] = $1,113.00

The total return on investment of the Notes is 11.13%.

Example 2: The value of the Reference Asset decreases from an Initial Value of 100.00 to a Final Value of 95.00.

Because the Reference Asset Return is less than 0.00% but greater than or equal to -10.00%, you will receive a payment at maturity of $950.00 per $1,000 principal amount Note that you hold, calculated as follows:

$1,000 + [$1,000 × Reference Asset Return]

$1,000 + [$1,000 × -5.00] = $950.00

The total return on investment of the Notes is -5.00%.

Example 3: The value of the Reference Asset decreases from an Initial Value of 100.00 to a Final Value of 80.00.

Because the Reference Asset Return is less than -10.00%, you will receive a payment at maturity of $900.00 per $1,000 principal amount Note that you hold, which is the Minimum Payment at Maturity.

The total return on investment of the Notes is -10.00%, which reflects the Minimum Payment at Maturity.

PS-5

SELECTED RISK CONSIDERATIONS

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

·You May Lose up to 10.00% of the Principal Amount of Your Notes—The Notes differ from ordinary debt securities in that the Issuer will not necessarily repay the full principal amount of the Notes at maturity. If the Reference Asset Return is less than 0.00%, you will lose 1.00% of the principal amount of your Notes for every 1.00% that the Reference Asset Return falls below 0.00%, subject to the Minimum Payment at Maturity of $900.00 per $1,000 principal amount Note. Accordingly, you may lose up to 10.00% of the principal amount of your Notes. Any payment on the Notes, including the repayment of principal, is subject to the credit risk of Barclays Bank PLC.

·The Payment at Maturity of Your Notes is Based Solely on the Closing Value of the Reference Asset on the Final Valuation Date—The Final Value (and resulting Reference Asset Return) will be based solely on the Closing Value of the Reference Asset on the Final Valuation Date. Accordingly, if the value of the Reference Asset drops on the Final Valuation Date, the payment at maturity on the Notes may be significantly less than it would have been had it been linked to the value of the Reference Asset at any time prior to such drop.

·Credit of Issuer—The Notes 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 Notes 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 Notes, and in the event Barclays Bank PLC were to default on its obligations, you may not receive any amounts owed to you under the terms of the Notes.

·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 any other agreements, arrangements or understandings between Barclays Bank PLC and any holder or beneficial owner of the Notes, by acquiring the Notes, each holder and beneficial owner of the Notes 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 Notes losing all or a part of the value of your investment in the Notes or receiving a different security from the Notes, which may be worth significantly less than the Notes 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 the beneficial owners of the Notes. The exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the Notes 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 Notes. 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 could materially adversely affect the value of the 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.

·Owning the Notes is Not the Same as Owning A Reference Asset or Any Securities to which A Reference Asset Provides Exposure—The return on the Notes may not reflect the return you would realize if you actually owned a Reference Asset or any securities to which a Reference Asset provides exposure. As a holder of the Notes, you will not have voting rights or rights to receive dividends or other distributions or any other rights that holders of a Reference Asset or any securities to which a Reference Asset provides exposure may have.

·Historical Performance of the Reference Asset Should Not Be Taken as Any Indication of the Future Performance of the Reference Asset Over the Term of the Notes—The value of the Reference Asset has fluctuated in the past and may, in the future, experience significant fluctuations. The historical performance of the Reference Asset is not an indication of the future performance of the Reference Asset over the term of the Notes. Therefore, the performance of the Reference Asset over the term of the Notes may bear no relation or resemblance to the historical performance of the Reference Asset.

·Certain Features of The Reference Asset Will Impact the Value of the Notes—The performance of the Reference Asset will not fully replicate the performance of its Underlying Index (as defined above), and the Reference Asset may hold securities not included in its Underlying Index. The value of the Reference Asset is subject to:

oManagement risk. This is the risk that the investment strategy for the Reference Asset, the implementation of which is subject to a number of constraints, may not produce the intended results. The Reference Asset’s investment adviser may have the right to use a portion of the Reference Asset’s assets to invest in shares of equity securities that are not included in its Underlying Index. The Reference Asset is not actively managed, and the Reference Asset’s investment adviser will generally not attempt to take defensive positions in declining markets.

PS-6

oDerivatives risk. The Reference Asset may invest in derivatives, including forward contracts, futures contracts, options on futures contracts, options and swaps. A derivative is a financial contract, the value of which depends on, or is derived from, the value of an underlying asset such as a security or an index. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices, and thus the Reference Asset’s losses may be greater than if the Reference Asset invested only in conventional securities.

oTransaction costs and fees. Unlike its Underlying Index, the Reference Asset will reflect transaction costs and fees that will reduce its performance relative to its Underlying Index.

Generally, the longer the time remaining to maturity, the more the market price of the Notes will be affected by the factors described above. In addition, the Reference Asset may diverge significantly from the performance of its Underlying Index due to differences in trading hours between the Reference Asset and the securities composing its Underlying Index or other circumstances. During periods of market volatility, the component securities held by the Reference Asset may be unavailable in the secondary market, market participants may be unable to calculate accurately the intraday net asset value per share of the Reference Asset and the liquidity of the Reference Asset may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares in the Reference Asset. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of the Reference Asset. As a result, under these circumstances, the market value of the Reference Asset may vary substantially from the net asset value per share of the Reference Asset. Because the Notes are linked to the performance of the Reference Asset and not its Underlying Index, the return on your Notes may be less than that of an alternative investment linked directly to its Underlying Index.

·Anti-dilution Protection Is Limited, and the Calculation Agent Has Discretion to Make Anti-dilution Adjustments—The Calculation Agent may in its sole discretion make adjustments affecting the amounts payable on the Notes upon the occurrence of certain events that the Calculation Agent determines have a diluting or concentrative effect on the theoretical value of the shares of the Reference Asset. However, the Calculation Agent might not make such adjustments in response to all events that could affect the shares of the Reference Asset. The occurrence of any such event and any adjustment made by the Calculation Agent (or a determination by the Calculation Agent not to make any adjustment) may adversely affect any amounts payable on the Notes. See “Reference Assets—Exchange-Traded Funds—Adjustments Relating to Securities with an Exchange-Traded Fund as a Reference Asset—Anti-dilution Adjustments” in the accompanying prospectus supplement.

·Adjustments to the Reference Asset or its Underlying Index Could Adversely Affect the Value of the Notes or Result in the Notes Being Accelerated— The investment adviser of the Reference Asset may add, delete or substitute the component securities held by the Reference Asset or make changes to its investment strategy, and the sponsor of the Underlying Index may add, delete, substitute or adjust the securities composing the Underlying Index or make other methodological changes to the Underlying Index that could affect its performance. In addition, if the shares of the Reference Asset are delisted or if the Reference Asset is liquidated or otherwise terminated, the Calculation Agent may select a successor fund that the Calculation Agent determines to be comparable to the Reference Asset or, if no successor fund is available, the Maturity Date of the Notes will be accelerated for a payment determined by the Calculation Agent. Any of these actions could adversely affect the value of the Reference Asset and, consequently, the value of the Notes. Any amount payable upon acceleration could be significantly less than the amount(s) that would be due on the securities if they were not accelerated. See “Reference Assets—Exchange-Traded Funds—Adjustments Relating to Securities with an Exchange-Traded Fund as a Reference Asset—Discontinuance of an Exchange-Traded Fund” in the accompanying prospectus supplement.

·The Notes Are Subject to Risks Associated with Non-U.S. Securities Markets—The equity securities held by the Reference Asset are issued by non-U.S. companies in non-U.S. securities markets. Investments in securities linked to the value of such non-U.S. equity securities, such as the Notes, involve risks associated with the securities markets in the home countries of the issuers of those non-U.S. equity securities, including risks of volatility in those markets, governmental intervention in those markets and cross shareholdings in companies in certain countries. Also, there is generally less publicly available information about companies in some of these jurisdictions than there is about U.S. companies that are subject to the reporting requirements of the SEC, and generally non-U.S. companies are subject to accounting, auditing and financial reporting standards and requirements and securities trading rules different from those applicable to U.S. reporting companies. The prices of securities in non-U.S. markets may be affected by political, economic, financial and social factors in those countries, or global regions, including changes in government, economic and fiscal policies and currency exchange laws.

·The Notes Are Subject to Currency Exchange Risk—Because the prices of the Reference Asset are related to the U.S. dollar value of the component securities held by the Reference Asset, the prices of the Reference Asset will be exposed to the currency exchange rate risk with respect to each of the currencies in which the component securities held by the Reference Asset trade. An investor’s net exposure will depend on the extent to which each of those non-U.S. currencies strengthens or weakens against the U.S. dollar and the relative weight of the component securities denominated in those non-U.S. currencies. If, taking into account the relevant weighting, the U.S. dollar strengthens against those non-U.S. currencies, the prices of the Reference Asset will be adversely affected and any payments on the Notes may be reduced.

Exchange rate movements for a particular currency are volatile and are the result of numerous factors, including the supply of, and the demand for, those currencies, as well as government policy, intervention or actions, but are also influenced significantly from time to time by political or economic developments, and by macroeconomic factors and speculative actions related to the relevant region. Of particular importance to potential currency exchange risk are:

PS-7

·existing and expected rates of inflation;

·existing and expected interest rate levels;

·the balance of payments between the countries represented in the Reference Asset and the United States; and

·the extent of governmental surpluses or deficits in the countries represented in the Reference Asset and the United States.

All of these factors are in turn sensitive to the monetary, fiscal and trade policies pursued by the governments of the countries represented in the Reference Asset, the United States and other countries important to international trade and finance.

·The Estimated Value of Your Notes is Expected to be Lower Than the Initial Issue Price of Your Notes—The estimated value of your Notes on the Initial Valuation Date is expected to be lower, and may be significantly lower, than the initial issue price of your Notes. The difference between the initial issue price of your Notes and the estimated value of the Notes is expected as a result of certain factors, such as 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 Notes, the estimated cost which we may incur in hedging our obligations under the Notes, and estimated development and other costs which we may incur in connection with the Notes.

·The Estimated Value of Your Notes 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 Notes on the Initial Valuation 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 Notes 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 Notes on the Initial Valuation 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 Notes may not be consistent with those of other financial institutions which may be purchasers or sellers of Notes in the secondary market. As a result, the secondary market price of your Notes may be materially different from the estimated value of the Notes determined by reference to our internal pricing models.

·The Estimated Value of Your Notes Is Not a Prediction of the Prices at Which You May Sell Your Notes in the Secondary Market, if any, and Such Secondary Market Prices, If Any, Will Likely be Lower Than the Initial Issue Price of Your Notes and May be Lower Than the Estimated Value of Your Notes—The estimated value of the Notes 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 Notes 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 Notes 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 Notes. Further, as secondary market prices of your Notes 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 Notes such as fees, commissions, discounts, and the costs of hedging our obligations under the Notes, secondary market prices of your Notes will likely be lower than the initial issue price of your Notes. As a result, the price at which Barclays Capital Inc., other affiliates of ours or third parties may be willing to purchase the Notes from you in secondary market transactions, if any, will likely be lower than the price you paid for your Notes, and any sale prior to the Maturity Date could result in a substantial loss to you.

·The Temporary Price at Which We May Initially Buy The Notes in the Secondary Market And the Value We May Initially Use for Customer Account Statements, If We Provide Any Customer Account Statements At All, May Not Be Indicative of Future Prices of Your Notes—Assuming that all relevant factors remain constant after the Initial Valuation Date, the price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market (if Barclays Capital Inc. makes a market in the Notes, which it is not obligated to do) 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 of the Notes on the Initial Valuation Date, as well as the secondary market value of the Notes, for a temporary period after the initial Issue Date of the Notes. The price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market and the value that we may initially use for customer account statements may not be indicative of future prices of your Notes.

·We and Our Affiliates May Engage in Various Activities or Make Determinations That Could Materially Affect the Notes in Various Ways and Create Conflicts of Interest—We and our affiliates play a variety of roles in connection with the issuance of the Notes, as described below. In performing these roles, our and our affiliates’ economic interests are potentially adverse to your interests as an investor in the Notes.

In connection with our normal business activities and in connection with hedging our obligations under the Notes, 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 Reference Asset or its components. In any such market making, trading and hedging activity, and other financial services, we or our affiliates

PS-8

may take positions or take actions that are inconsistent with, or adverse to, the investment objectives of the holders of the Notes. We and our affiliates have no obligation to take the needs of any buyer, seller or holder of the Notes 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 Notes.

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

In addition to the activities described above, we will also act as the Calculation Agent for the Notes. As Calculation Agent, we will determine any values of the Reference Asset and make any other determinations necessary to calculate any payments on the Notes. In making these determinations, the Calculation Agent may be required to make discretionary judgements relating to the Reference Assets, including determining whether a market disruption event has occurred or whether certain adjustments to the Reference Assets or other terms of the Notes are necessary, as further described in the accompanying prospectus supplement. In making these discretionary judgments, our economic interests are potentially adverse to your interests as an investor in the Notes, and any of these determinations may adversely affect any payments on the Notes.

·Lack of Liquidity—The Notes 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 Notes but are not required to do so, and may discontinue any such secondary market making at any time, without notice. Barclays Capital Inc. may at any time hold unsold inventory, which may inhibit the development of a secondary market for the Notes. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily. Because other dealers are not likely to make a secondary market for the Notes, the price at which you may be able to trade your Notes 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 Notes. The Notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your Notes to maturity.

·Tax Treatment—As discussed further below under “Tax Considerations” and in the accompanying prospectus supplement, if you are a U.S. individual or taxable entity, you should be required to accrue interest on a current basis in respect of the Notes over their term based on the comparable yield for the Notes and pay tax accordingly, even though you will not receive any payments from us until maturity. This comparable yield is determined solely to calculate the amount on which you will be taxed prior to maturity and is neither a prediction nor a guarantee of what the actual yield will be.

·Many Economic and Market Factors Will Impact the Value of the Notes—The value of the Notes will be affected by a number of economic and market factors that interact in complex and unpredictable ways and that may either offset or magnify each other, including:

othe market price of, dividend rate on and expected volatility of the Reference Asset and the components of the Reference Asset;

othe time to maturity of the Notes;

ointerest and yield rates in the market generally;

oa variety of economic, financial, political, regulatory or judicial events;

othe exchange rates relative to the U.S. dollar with respect to each of the currencies in which the components of the Reference Asset trades;

osupply and demand for the Notes; and

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

TAX CONSIDERATIONS

You should review carefully the sections entitled “Material U.S. Federal Income Tax Consequences—Tax Consequences to U.S. Holders—Notes Treated as Indebtedness for U.S. Federal Income Tax Purposes” and, if you are a non-U.S. holder, “—Tax Consequences to Non-U.S. Holders,” in the accompanying prospectus supplement. The discussion below applies to you only if you are an initial purchaser of the Notes; if you are a secondary purchaser of the Notes, the tax consequences to you may be different. Notwithstanding that the Notes do not provide for the full repayment of their principal amount at or prior to maturity, in the opinion of our special tax counsel, Davis Polk & Wardwell LLP, the Notes should be treated as debt instruments for U.S. federal income tax purposes. The remainder of this discussion assumes that this treatment is correct.

Assuming the treatment described above is correct, in the opinion of our special tax counsel, the Notes will be treated as “contingent payment debt instruments” for U.S. federal income tax purposes, as described under “—Contingent Payment Debt Instruments” in the accompanying prospectus supplement. The remainder of this discussion assumes that this treatment is correct.

Regardless of your method of accounting for U.S. federal income tax purposes, you generally will be required to accrue taxable interest income in each year on a constant yield to maturity basis at the “comparable yield,” as determined by us, even though we will not be required to make any payment with respect to the Notes prior to maturity. Upon a sale or exchange (including redemption at maturity), you generally will recognize taxable income or loss equal to the difference between the amount received from the sale or exchange and your adjusted tax basis in the Notes. You generally must treat any income as interest income and any loss as ordinary loss to the extent of previous interest inclusions, and the balance as capital loss. The deductibility of capital losses is subject to limitations.

The discussions herein and in the accompanying prospectus supplement do not address the consequences to taxpayers subject to special tax accounting rules under Section 451(b).

After the original issue date, you may obtain the comparable yield and the projected payment schedule by requesting them from Barclays Cross Asset Sales Americas, at (212) 528-7198. Neither the comparable yield nor the projected payment schedule constitutes a representation by us regarding the actual amount that we will pay on the Notes.

You should consult your tax advisor regarding the U.S. federal tax consequences of an investment in the Notes, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Non-U.S. Holders. We do not believe that non-U.S. holders should be required to provide a Form W-8 in order to avoid 30% U.S. withholding tax with respect to the excess (if any) of the Payment at Maturity over the face amount of the Notes, although the Internal Revenue Service (the “IRS”) could challenge this position. However, non-U.S. holders should in any event expect to be required to provide appropriate Forms W-8 or other documentation in order to establish an exemption from backup withholding, as described under the heading “—Information Reporting and Backup Withholding” in the accompanying prospectus supplement. If any withholding is required, we will not be required to pay any additional amounts with respect to amounts withheld.

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, 2021 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 determination that the Notes do not have a “delta of one” within the meaning of the regulations, we expect that these regulations will not apply to the Notes with regard to non-U.S. holders. 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 Notes. You should consult your tax advisor regarding the potential application of Section 871(m) to the Notes.

SUPPLEMENTAL PLAN OF DISTRIBUTION

We will agree to sell to Barclays Capital Inc. (the “Agent”), and the Agent will agree to purchase from us, the principal amount of the Notes, and at the price, specified on the cover of the related pricing supplement, the document that will be filed pursuant to Rule 424(b) containing the final pricing terms of the Notes. The Agent will commit to take and pay for all of the Notes, if any are taken.
