¹  Three year (“3Y”) returns are reported on a per annum basis i.e. annualized according to a simple three year period.

²  Note: Volatility is calculated based on daily natural logarithm returns, except for the indices where the benchmark is published monthly, in which case both the index and the benchmark are based on monthly natural logarithm returns. Volatility is calculated as a square root of the product of (1) 252 (for daily data) or 12 (for monthly data) and (2) the sum of the squared differences between the daily or monthly natural logarithm returns and the daily or monthly return averages divided by the number of returns in the observation period minus one.

³  HFRX RV: Volatility Index (HFRXVOL <INDEX>) is published monthly with one month lag on the last day of each month i.e. above performances are versus the end of June 2012.

CERTAIN RISK CONSIDERATIONS

Some of the risks related to Structured Investments are described below. Before investing in any Structured Investment, you should read the relevant prospectus or disclosure statement for a detailed explanation of the terms, risks, tax treatment and other relevant information of the investment. We also urge you to consult your financial, tax and legal advisors before investing.

Credit of issuer

The types of Structured Investments detailed in this document 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 Structured Investments, including any payment of principal, depends on the ability of Barclays Bank PLC to meet 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 Structured Investments. In the event Barclays Bank PLC were to default on its obligations, you may not receive the amounts owed to you under the terms of the Structured Investments.

No rights to the reference asset

As a holder of the Structured Investments, you will not have any rights (including any voting rights or rights to receive cash dividends or other distributions) that the holders of any reference asset or components of the reference asset would have.

Limited liquidity

You should be willing to hold the Structured Investments to maturity. There may be little or no secondary market for the Structured Investments. Barclays Capital Inc. or other affiliates of Barclays Bank PLC intend to make a secondary market in the Structured Investments. 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 Structured Investments. If you sell Structured Investments 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 Structured Investments prior to maturity

The original issue price of the Structured Investments includes the agent’s commission and the cost of hedging our obligations under the Structured Investments. 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 Structured Investments from you in secondary market transactions may be lower than the original issue price, and any sale prior to the maturity date of the Structured Investment could result in a substantial loss to you.

Your own evaluation of the merits

In connection with any purchase of a Structured Investment, 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 reference asset and not rely on our views in any respect. You should make a complete investigation as to the merits of an investment in a Structured Investment before investing.

-6-

Historical results not indicative of future performance

The historical or hypothetical performance of the reference asset should not be taken as an indication of the future performance of the reference asset. It is impossible to predict whether the level, value or price of the reference asset will fall or rise during the term of the Structured Investments, 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 reference assets are not necessarily indicative of fluctuations or trends that may occur in the future.

Market risk

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

Price volatility

Movements in the levels, values or prices of the reference assets 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 reference assets will rise or fall during the term of the Structured Investments. Changes in the levels, values or prices of the reference assets will determine the payment on the Structured Investments. Therefore, you may receive less, and potentially substantially less, than the amount you initially invested in the Structured Investments if the levels, values or prices of the reference assets decline. Unless your Structured Investment is fully principal protected (in which case, all payments on the Structured Investment 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 Structured Investments

In addition to the level, value or price of the reference asset on any day, the market value of the Structured Investments 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 reference asset or its underlying components;

• the time to maturity of the Structured Investments;

• interest and yield rates in the market generally;

• a variety of economic, financial, political, regulatory or judicial events;

• supply and demand for the Structured Investments; and

• the creditworthiness of the issuer, including actual or anticipated downgrades in the credit ratings of the issuer.

-7-

Potential conflicts of interests

Barclays Bank PLC or one of its affiliates could serve as the calculation agent for the Structured Investments. The calculation agent will make determinations related to the Structured Investments, including calculating the amounts payable to you under the Structured Investments and making judgments related to the levels, values, prices or any other affected variable under certain circumstances. Conflicts of interest may arise in connection with Barclays Bank PLC or its affiliates performing the role of calculation agent under the Structured Investment.

If the Structured Investment were linked to one or more Barclays’ indices, Barclays Bank PLC is the index sponsor. The index sponsor is responsible for the composition, calculation and maintenance of the index and has the discretion in a number of circumstances to make judgments in connection with the composition, calculation and maintenance of the Index. The exercise of this discretion may present the index sponsor with significant conflicts of interest in light of the fact that Barclays Bank PLC is the issuer of the Structured Investments. The index sponsor has no obligation to take the needs of any buyer, seller or holder of the Structured Investments into consideration at any time.

In addition, Barclays Bank PLC and its affiliates play a variety of roles in connection with the issuance of the Structured Investments, including hedging its obligations under the Structured Investments. In performing these duties, the economic interests of Barclays Bank PLC and its affiliates are potentially adverse to your interests as an investor in the Structured Investments.

The Wealth and Investment Management division of Barclays may sell the Structured Investments to certain of its customers and may receive compensation from Barclays, as the issuer of the Structured Investments, in this capacity

The Wealth and Investment Management division of Barclays may offer Structured Investments to its clients and be compensated for doing so. The Wealth and Investment Management division of Barclays, functioning in the United States through Barclays Capital Inc., will be acting as agent for Barclays Bank PLC in connection with the distribution of the Structured Investments to you and, as such, its role may create a potential conflict of interest. The Wealth and Investment Management division of Barclays is not acting as your agent or investment adviser, and is not representing you in any capacity with respect to any purchase of the Structured Investments by you. If you are considering whether to invest in the Structured Investments through the Wealth and Investment Management division of Barclays, Barclays Bank PLC strongly urges you to seek independent financial and investment advice to assess the merits of such investment.

The Strategies Employed by the Indices are not Guaranteed to Succeed.

Each of the Barclays equity indices and reference assets referenced above is based on the premise(s) or strategies referenced above. There is no assurance that any of these premises or strategies will be successful and, accordingly, no assurances can be made that any such Barclays Capital equity indices or reference assets will appreciate during the term of any securities or products that may be linked to any such Barclays equities indices or underlying reference assets (the “Securities”). The issuance of Securities should not be deemed an assurance or guarantee by Barclays Bank PLC or any of its affiliates that the level of the underlying reference asset will increase, or that the Securities will generate a positive return.
