1 The investor fee is equal to the Yearly Fee times the principal amount of your securities times the index factor,
calculated on a daily basis in the following manner: The investor fee on the inception date will equal zero. On each subsequent calendar day until maturity or early redemption, the investor fee will increase by an amount equal to the Yearly Fee
times the principal amount of your securities times the index factor on that day (or, if such day is not a trading day, the index factor on the immediately preceding trading day) divided by 365. The index factor on any given day will be equal to the
closing value of the index on that day divided by the initial index level. The initial index level is the closing value of the index on the inception date of the securities.

Index returns are for illustrative purposes only and do not represent actual iPath ETN performance. Index performance
returns do not reflect any management fees, transaction costs or expenses. Indexes are unmanaged and one
cannot invest
directly in an index. Past performance does not guarantee future results. For current Index and

3 Standard deviation is a measure of variability from the expected value. Standard Deviation % Annualized is based on
monthly returns for 12/07-12/12, and describes how the annual returns in a given annual period are likely to differ from average annualized returns. Because the Standard Deviation % Annualized is based on historical data, it may not predict
variability in annualized performance of the ETNs in the future. Source: BlackRock, Barclays
4 Correlations
based on monthly returns for 12/07-12/12. Correlation is the term used to describe the statistical relationship between two or more quantities or variables. Perfectly correlated assets will have a correlation coefficient of one, while the
correlation coefficient will be zero when returns on two assets are completely independent. Source: BlackRock, Barclays
Selected Risk Considerations
An investment in the
iPath ETNs described herein (the ETNs) involves risks. Selected risks are summarized here, but we urge you to read the more detailed explanation of risks described under Risk Factors in the applicable prospectus supplement
and pricing supplement.
You May Lose Some or All of Your Principal: The ETNs are exposed to any decrease in
the level of the underlying index between the inception date and the applicable valuation date. Additionally, if the level of the underlying index is insufficient to offset the negative effect of the investor fee and other applicable costs, you will
lose some or all of your investment at maturity or upon redemption, even if the value of such index has increased. Because the ETNs are subject to an investor fee and any other applicable costs, the return on the ETNs will always be lower than the
total return on a direct investment in the index components. The ETNs are riskier than ordinary unsecured debt securities and have no principal protection.
Credit of Barclays Bank PLC: The ETNs are unsecured debt obligations of the issuer, Barclays Bank PLC, and are not, either directly or indirectly, an obligation of or guaranteed by any
third party. Any payment to be made on the ETNs, including any payment at maturity or upon redemption, 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 will affect the market value, if any, of the ETNs prior to maturity or redemption. In addition, 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
ETNs.
Market and Volatility Risk: The prices of physical commodities, including the commodities underlying the
index components, can fluctuate widely due to supply and demand disruptions in major producing or consuming regions. Additionally, the market value of the ETNs may be influenced by many unpredictable factors including changes in supply and demand
relationships, governmental policies and economic events.
Concentration Risk: Because the ETNs are linked to
an index composed of futures contracts on a single commodity or in only one commodity sector, the ETNs are less diversified than other funds. The ETNs can therefore experience greater volatility than other funds or investments.
A Trading Market for the ETNs May Not Develop: Although the ETNs are listed on NYSE Arca, a trading market for the ETNs
may not develop and the liquidity I1212 of the ETNs may be limited, as we are not required to maintain any listing of the ETNs.

Tracking error refers to the under/over performance differential of an ETN versus its underlying index over a given time
period, after
accounting for the ETNs fees and costs. One cannot invest directly in an index.
No Interest Payments from the ETNs: You may not receive any interest payments on the ETNs.
Restrictions on the Minimum Number of ETNs and Date Restrictions for Redemptions: You must redeem at least 50,000 ETNs of
the same series at one time in order to exercise your right to redeem your ETNs on any redemption date. You may only redeem your ETNs on a redemption date if we receive a notice of redemption from you by certain dates and times as set forth in the
pricing supplement.
Uncertain Tax Treatment: Significant aspects of the tax treatment of the ETNs are
uncertain. You should consult your own tax advisor about your own tax situation.
