What are iPath Exchange Traded Notes?

iPath Exchange Traded Notes (“iPath ETNs”) are senior, unsecured, unsubordinated debt securities issued by Barclays Bank PLC. They are designed to provide investors with a new way to access the returns of market benchmarks or strategies. iPath ETNs are not equities or index funds, but they do share several characteristics. For example, like equities, they trade on exchange. Like an index fund, they are linked to the return of a benchmark index.

What are the advantages of iPath ETNs?

iPath ETNs provide investors with convenient exposure to the returns of market benchmarks, less investor fees1,while maintaining the ease of trading similar to an equity. The iPath ETN structure is designed to allow investors cost effective exposure to investments in previously expensive or difficult-to-reach market sectors or strategies.

Where can I buy iPath ETNs?

1) Sell in the secondary market during exchange trading hours via any local brokerage.

2) Redeem a large block of securities, directly with the issuer, Barclays Bank PLC, subject to the terms and procedures described in the relevant offering documents2. A redemption charge may apply for certain iPath ETNs.

No. Investors will receive the performance of the index to which the iPath ETN is linked, less investor fee. The index may go up or down. Even if the index goes up, investors may not recover their principal once investor fees are deducted.

Do the iPath ETNs currently available make dividend distributions?

No.

Do the iPath ETNs currently available make interest payments?

No.

Are iPath ETNs rated?

No. The iPath ETNs are not rated, but rely on the ratings of their issuer, Barclays Bank PLC3.

Who is the issuer?

Barclays Bank PLC. Barclays Bank PLC is a major global financial services provider engaged in retail and commercial banking, credit cards, investment banking, wealth management and investment management services, with an extensive international presence in Europe, the USA, Africa and Asia. With over 300 years of history and expertise in banking, Barclays operates in over 50 countries and employs over 145,000 people. Barclays moves, lends, invests and protects money for over 49 million customers and clients worldwide. For further information about Barclays Bank PLC, please visit our website www.barclays.com.

How are the returns of iPath ETNs calculated?

iPath ETNs are designed to provide investors a return that is linked to the performance of an index, less investor fee.

Are iPath ETNs linked to commodity indices regulated by Commodity Futures Trading Commission (‘CFTC’)?

No. iPath ETNs are debt securities issued by Barclays Bank PLC and are not regulated by CFTC; however, futures contracts underlying the relevant market index may be regulated by CFTC.

Is a net asset value (NAV) calculated?

No. As iPath ETNs are debt securities, and not mutual funds, they will not have a NAV.

Is an intrinsic value calculated?

An intraday ‘indicative value’ meant to approximate the economic value of each iPath ETN is calculated and published by Bloomberg or a successor. Additionally, the indicative value of each iPath ETN is calculated and published on the www.iPathAsia.com.

Do iPath ETNs trade at their indicative value?

The indicative value calculation is provided for reference purposes only. It is not intended as a price or quotation, or as an offer or solicitation for the purchase, sale, redemption, or termination of the iPath ETNs, nor does it reflect hedging or transaction costs, credit considerations, market liquidity, or bid-offer spreads. Published index levels from the sponsors of the indexes underlying the iPath ETNs may occasionally be subject to delay or postponement. Any such delays or postponements will affect the Current Index Level and therefore the indicative value of your iPath ETNs. Index levels provided by the sponsors of the indexes underlying the iPath ETNs do not necessarily reflect the depth and liquidity of the underlying relevant market. For this reason and others, the actual trading price of the iPath ETNs may be different from their indicative value.

In addition to being available for trading on an exchange, the early redemption feature allows a large block of securities, to be redeemed directly with Barclays Bank PLC for the redemption value, as described in the applicable offering documents. The historical daily indicative value is published each day at www.iPathAsia.com. The redemption feature is intended to induce arbitrageurs to counteract any trading of the iPath ETNs at a premium or discount to their indicative value, though there can be no assurance that arbitrageurs will employ the redemption feature in this manner.

What is the redemption charge?

The redemption charge is one-time transaction charge imposed only in the case of early redemptions for certain iPath ETNs. The charge is intended to allow the issuer to recoup brokerage and other costs incurred in connection with an early redemption (although the proceeds from the charge may be more or less than such costs). Investors transacting on the secondary market will not incur a redemption charge.

If Barclays Bank PLC’s credit rating is downgraded, what happens to the indicative value?

The indicative value calculation of the iPath ETNs will not change in response to a Barclays Bank PLC credit event. However, the trading price of the iPath ETNs may be adversely impacted.
