Selected Risk Considerations

Please see the prospectus, prospectus supplement, index supplement (if applicable) and the related free writing prospectus for a more detailed discussion of risks, conflicts of interest, and tax consequences associated with an investment in the notes.

Credit of the Issuer.  The types of notes detailed herein are senior unsecured 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, depends on the ability of Barclays Bank PLC to satisfy its obligations as they come due. 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 was to default on its obligations, the investor may not receive the amounts owed under the terms of the notes.

No rights to the Underlier.  As a holder of the notes, the investor will not have any rights (including any voting rights or rights to receive cash dividends or other distributions) that the holders of any Underlier or components of the Underlier would have.

Limited liquidity.  The investor should be willing to hold the notes to maturity.  There may be little or no secondary market for the notes. Barclays Capital Inc. and other affiliates of Barclays Bank PLC intend to make a secondary market in the notes.  If they do, however, they are not required to do so and may stop at any time, and there may not be a trading market in the notes.  If you sell the notes prior to their maturity, you may have to sell them at a substantial loss.

Certain built-in costs are likely to adversely affect the value of the notes prior to maturity.  The original issue price of the notes includes the agent’s commission and the cost of hedging our obligations under the notes.  As a result, assuming no change in market conditions or any other relevant factors, the price, if any, at which Barclays Capital Inc. or other affiliates of Barclays Bank PLC will be willing to purchase notes from you in secondary market transactions may be lower than the original issue price, and any sale prior to the maturity date of the notes could result in a substantial loss to you.

Your own evaluation of the merits.  In connection with any purchase of the notes, we urge you to consult your own financial, tax and legal advisors as to the risks involved in an investment in the product and to investigate the Underlier and not rely on our views in any respect.  You should make a complete investigation as to the merits of an investment in the notes before investing.

Historical results not indicative of future performance.  The historical or hypothetical performance of the Underlier should not be taken as an indication of the future performance of the Underlier.  It is impossible to predict whether the price, value or price of the Underlier will fall or rise during the term of the notes, in particular in the environment in recent periods which has been characterized by unprecedented volatility across a wide range of asset classes.  Past fluctuations and trends in the Underliers are not necessarily indicative of fluctuations or trends that may occur in the future.

Market risk.  The return, if any, on the notes is dependent on the performance of the Underlier to which it is linked.  Thus, changes in the level, value or price of the Underlier will determine the amount payable on the notes.  Unless your notes are fully principal protected (in which case, all payments on the notes are subject to the credit risk of Barclays Bank PLC as the issuer), if the level, value or price of the Underlier declines, you may lose some or all of your investment at maturity.

Price volatility.  Movements in the levels, values or prices of the Underliers and their respective components are unpredictable and volatile, and are influenced by complex and interrelated political, economic, financial, regulatory, geographic, judicial and other factors.  As a result, it is impossible to predict whether the levels, values or prices of the Underliers will rise or fall during the term of the notes.  Changes in the levels, values or prices of the Underliers will determine the payment on the notes.  Therefore, you may receive less, and potentially substantially less, than the amount you initially invested in the notes if the levels, values or prices of the Underliers decline.  Unless your notes are fully principal protected (in which case, all payments on the notes are subject to the credit risk of Barclays Bank PLC as the issuer), you should be willing and able to bear the loss of some or all of your investment.

Many unpredictable factors, including economic and market factors, will impact the value of the notes.  In addition to the level, value or price of the Underlier on any day, the market value of the notes 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 Underlier or its underlying components;  the time to maturity of the notes; interest and yield rates in the market generally; a variety of economic, financial, political, regulatory or judicial events; supply and demand for the notes; and the creditworthiness of the issuer, including actual or anticipated downgrades in the credit ratings of the issuer.

Potential conflicts of interest.  Barclays Bank PLC and its affiliates play a variety of roles in connection with the issuance of the notes, including acting as calculation agent and hedging its obligations under the notes.  In performing these duties, the economic interests of the calculation agent and other affiliates of the issuer are potentially adverse to your interests as an investor in the notes.

Tax treatment.  Significant aspects of the tax treatment of the notes are uncertain.  See “Selected Purchase Considerations—Tax Consequences” in the accompanying FWP.

An investment in the notes involves significant risk. You should carefully consider the risks of an investment in the notes, including those discussed above. In addition, you should carefully consider the “Risk Factors” beginning on page S-6 of the prospectus supplement, “Risk Factors” beginning on page IS-2 of the index supplement (if applicable) and “Selected Risk Considerations” beginning on page FWP-5 of the related free writing prospectus.
