Transparent Performance

Principal Amount of iPath ETNs x Index Factor – Investor FeeYearly Fee x Principal Amount x Index Factor

The investor fee is calculated cumulatively based on the Yearly Fee and the performance of the underlying index or currency exchange rate and increases each day based on the level of the index or currency exchange rate on that day. Because the investor fee reduces the amount of your return at maturity or upon redemption, if the value of the underlying decreases or does not increase significantly, you may receive less than the principal amount of your investment at maturity or upon redemption. For a more complete description of how the investor fee is calculated, please see the applicable product page and Pricing Supplement at www.iPathETN.com.

An investment in iPath ETNs involves risks, including possible loss of principal. For a description of the main risks see “Risk Factors” in the applicable prospectus.

Barclays Bank PLC has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus and other documents Barclays Bank PLC has filed with the SEC for more complete information about the issuer and this offering. You may get these documents for free by visiting www.iPathETN.com or EDGAR on the SEC website at www.sec.gov. Alternatively, Barclays Bank PLC will arrange for Barclays Capital Inc. to send you the prospectus if you request it by calling toll-free 1-877-76-iPATH, or you may request a copy from any other dealer participating in the offering.

Barclays Global Investors Fund Distribution Company, an affiliate of Barclays Global Investors, N.A. (“BGINA”), assists in the promotion of the Securities. Barclays Global Investors, N.A. and Barclays Capital Inc. (“BCI”) are affiliates of Barclays Bank PLC.

iPath ETNs (the “Securities”) are unsecured obligations of Barclays Bank PLC and are not secured debt. The Securities are riskier than ordinary unsecured debt securities and have no principal protection. Risks of investing in the Securities include limited portfolio diversification, trade price fluctuations, uncertain principal repayment, and illiquidity. Investing in the Securities is not equivalent to direct investment in index or index components. The investor fee will reduce the amount of your return at maturity or on redemption, and as a result you may receive less than the principal amount of your investment at maturity or upon redemption of your Securities even if the value of the relevant index has increased. An investment in iPath ETNs may not be suitable for all investors.

The Securities may be sold throughout the day on the exchange through any brokerage account. There are restrictions on the minimum number of Securities you may redeem directly with the issuer as specified in the applicable prospectus. Commissions may apply and there are tax consequences in the event of sale, redemption or maturity of Securities. Sales in the secondary market may result in significant losses.

iPath ETNs typically have lower investor fees than currently existing mutual funds that invest in similar markets and are available to retail investors. Buying and selling iPath ETNs will result in brokerage commissions. BGINA and its affiliates, and BCI and its affiliates do not provide tax advice and nothing contained herein should be construed to be tax advice. Please be advised that any discussion of U.S. tax matters contained herein (including any attachments) (i) is not intended or written to be used, and cannot be used, by you for the purpose of avoiding U.S. tax- related penalties; and (ii) was written to support the promotion or marketing of the transactions or other matters addressed herein. Accordingly, you should seek advice based on your particular circumstances from an independent tax advisor. A “buy-write” strategy consists of a hypothetical portfolio consisting of a “long” position in the components of an underlying index and the sale of a succession of one-month, at- or slightly out-of-the-money call options on the underlying index or its components. An investment in iPath ETNs linked to buy-write strategies limit participation in any appreciation of the underlying indexes above the strike price of the call options sold, but exposure to any decline in the value of the indexes will not be limited. Stock and option prices may change unpredictably, affecting the value of the buy- write strategy and, consequently, the value of your Securities in unforeseeable ways. The index components for iPath ETNs linked to commodities indexes are concentrated in the commodities sector. The market value of the Securities may be influenced by many unpredictable factors, including, where applicable, highly volatile commodities prices, changes in supply and demand relationships; weather; agriculture; trade; pestilence; changes in interest rates; and monetary and other governmental policies, action and inaction. Index components that track the performance of a single commodity, or index components concentrated in a single sector, are speculative and may typically exhibit higher volatility. The current or “spot” prices of the underlying physical commodities may also affect, in a volatile and inconsistent manner, the prices of futures contracts in respect of the relevant commodity. These factors may affect the value of the index and the value of your Securities in varying ways.

In addition to factors affecting commodities generally, index components composed of futures contracts on industrial metals or energy-related commodities may be subject to additional factors specific to industrial metals or energy-related commodities that might cause price volatility. These may include changes in the level of industrial or commercial activity using industrial metals or with high levels of energy demand; the availability and price of substitutes such as man-made or synthetic substitutes or alternative sources of energy; disruptions in the supply chain; adjustments to inventory; variations in production costs; costs associated with regulatory compliance, including environmental regulations; and changes in industrial, government and consumer demand, both in individual consuming nations and internationally. Index components composed of futures contracts on agricultural products may be subject to additional factors specific to agricultural products that might cause price volatility. These may include weather conditions, including floods, drought and freezing conditions; changes in government policies; planting decisions; and changes in demand for agricultural products, both with end users and as inputs into various industries. Index components composed of futures contracts on precious metals may be subject to additional factors specific to precious metals that might cause price volatility. These may include disruptions in the supply chain, variations in production costs, costs associated with regulatory compliance, including environmental regulations, changes in industrial, government and consumer demand, and in the case of gold and silver, precious metal leasing rates, currency exchange rates, the level of economic growth and inflation and the degree to which consumers, governments, corporate and financial institutions hold physical gold or silver as a safe haven asset (hoarding) which may be caused by a banking crisis/recovery, a rapid change in the value of other assets (both financial and physical) or changes in the level of geopolitical tension.

An investment in iPath ETNs linked to the performance of a foreign currency exchange rate is subject to risks associated with fluctuations, particularly a decline, in the price of the applicable single foreign currency relative to the U.S. dollar. Factors that may have the effect of causing a decline in the price of a foreign currency include national debt levels and trade deficits, domestic and foreign inflation rates, domestic and foreign interest rates, and global or regional economic, financial, political, regulatory, geographical or judicial events. Currency exchange rates may be extremely volatile, and exposure to a single currency can lead to significant losses.

An investment in the iPath ETNs linked to the MSCI India Total Return IndexSM may carry risks similar to a concentrated securities investment in a single region. International investments may involve risk of capital loss from unfavorable fluctuation in currency values, from differences in generally accepted accounting principles or from economic or political instability in other nations. Emerging markets involve heightened risks related to the same factors as well as increased volatility and lower trading volume. Securities focusing on a single country may be subject to higher volatility.

An investment in iPath ETNs linked to the performance of the Barclays Intelligent Carry IndexTM is subject to risks associated with fluctuations, particularly a decline, in the value of the index. Because the carry trade involves investing in high-yielding currencies with the exposure financed by borrowings in low-yielding currencies, the success of the index strategy, the level of the index and the market value of the securities will depend on the exchange rates and interest rates applicable to the index constituent currencies. If the applicable exchange rates or interest rates move against the direction targeted by the index strategy, the level of the index, and the market value of the securities, will decline. Factors that may contribute to volatile fluctuations in the index include exchange rates applicable to the index constituent currencies, interest rates applicable to the constituent currencies, the prevailing interest rate environment, and global or regional economic, financial, political, regulatory, geographical or judicial events that affect exchange rates and interest rates.

An investment in iPath ETNs linked to the performance of the Barclays Capital Global Carbon Index Total ReturnTM is subject to risks associated with fluctuations, particularly a decline, in the performance of the index caused by unpredictable volatility and movement in the prices of the index components. Trading in futures contracts on carbon emissions commodities, including trading in the index components, is speculative and can be extremely volatile. The commodity futures markets are subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets, the participation of speculators and government regulation and intervention. Market prices of the index components may fluctuate rapidly based on numerous factors including but not limited to changes in supply and demand, domestic and foreign political or government actions and technological developments. These factors could adversely affect the value of the Index and, therefore, the value of your Securities.

Cap & Trade mechanisms have arisen primarily due to relative international consensus on the correlation between the rise in Green House Gas emissions and the onset of Global Warming. Accordingly, changes in regulation and enforcement of Cap & Trade mechanisms as a result of changes in international consensus can adversely affect market behavior and the value of the Securities.

An investment in iPath ETNs linked to the performance of the S&P 500 VIX Short-Term Futures™ Index TR and the S&P 500 VIX Mid-Term Futures™ Index TR is subject to risks associated with fluctuations, particularly a decline, in the performance of each index. Because the performance of each index is linked to the CBOE Volatility Index (the “VIX Index”), the performance of each index will depend on many factors including, the level of the S&P 500® Index, the prices of options on the S&P 500® Index, and the level of the VIX Index which may change unpredictably, affecting the value of futures contracts on the VIX Index and, consequently, the level of each index. Additional factors that may contribute to fluctuations in the level of each index include prevailing market prices and forward volatility levels of the U.S. stock markets and the equity securities included in the S&P 500® Index, the prevailing market prices of options on the VIX Index, relevant futures contracts on the VIX Index, or any other financial instruments related to the S&P 500® Index and the VIX Index, interest rates, supply and demand in the listed and over-the-counter equity derivative markets as well as hedging activities in the equity-linked structured product markets.
