Executive Summary

Barclays Voyager Indices (“Voyager”) are designed to provide investors exposure to commodities while limiting the

potential downside of commodities investments.

Voyager employs an “Alpha Signal Test” twice a month that aims to identify an upward (bullish) market trend or

downward (bearish) market trend for the component commodities that comprise a reference index (such as DJUBSCISM

or S&P GSCI®) by analyzing historical or hypothetical historical price data.

If the Alpha Signal Test identifies a bullish market trend in a particular component commodity, then Voyager will

maintain a directional long position for that component commodity. In such cases, Voyager will be exposed to the

price performance of the underlying futures contracts for that component commodity.

If, on the other hand, the Alpha Test Signal identifies a bearish market trend in a particular Index Commodity, then

Voyager will create a market neutral allocation for that component commodity.

Executive Summary

Voyager aims to:

– Provide directionally long “beta” exposure during bullish markets and market neutral “alpha” exposure during bearish

markets.

the drawdown risk long only – Reduce associated with commodity index investing.

– Deliver absolute returns.

Voyager employs signals that identify if a commodity is in a bullish or bearish environment and allocates accordingly to a long

or long/short position in such commodity.

The Voyager signals are tested twice per month on a commodity by commodity basis and are based on moving average and

convergence measures of the underlying commodity futures contracts.

Voyager applied to DJ-UBSCISM has historically outperformed1 the DJ-UBSCISM

– Annualized outperformance1 of ~11.5%

– Reduced maximum drawdown1 by over 25%

Moving Average

Moving average is the average price over a specified time period and is perhaps the most commonly used

indicator in technical analysis.

Moving averages tend to smooth out short-term fluctuations and highlight longer-term trends or cycles.

Moving averages can be used to predict and/or confirm price trends and price direction.

Voyager Signals – Sector by Sector

Each commodity sector has its own supply and demand characteristics. As a result, different fast and slow

moving averages are utilized.1

The fast and slow moving averages for each sector were determined based on analysis of:

– Signal stability

– Calmar ratio2

Industrial Metals 30 190

Precious Metals N/A N/A

1 Precious metals are always allocated to a long nearby allocation.

2 Calmar ratio is a risk adjusted measure of return and is calculated by dividing average annual return by maximum drawdown using the last three years of data.

Maximum drawdown is defined as the largest decline from a historical peak to bottom in the value of the reference commodity.

Bullish signals are identified when either of the following 2 conditions is satisfied:

1) The fast moving average is above the slow moving average; or

2) The fast moving average is below the slow moving average, and the fast and slow moving averages are

converging

Bearish signals are identified when following condition is satisfied:

The fast moving average is below the slow moving average, and the fast and slow moving averages are diverging.

Convergence/divergence is calculated as the slope of the difference of the moving averages over 5 business days

prior to the Voyager allocation process.

Appendix: Pure Beta Methodology

Pure Beta – Overview of the Methodology

Pure Beta uses a quantitative approach to generate commodity returns that attempt to be more representative of the

commodity market by choosing a liquid tenor index along the curve that has specific characteristics (described on

the following pages).

Pure uses a multi-step process that is intended to an Beta multi allocation implement optimal allocation for each

commodity, that attempts to mitigate curve dislocation.

Definitions Investment Process

For each commodity:

Front Year Average Price1: Average of

settlement prices of the contracts in the

upcoming 12 months by their

Step 2 Calculate tenor liquidity percentages

Step 3

Liquidity screening: Any tenor index with

outstanding open interest less than 7% of

total open interest of the front year are

excluded from the allocation Determine Pure Beta allocation

Calculate dislocation Step 4

1 The “Front Year Average Price” for a commodity is constructed to measure the theoretical average price of the “front year” of futures contracts for that commodity, weighted by open interest for

such futures contracts.

Traditional Commodity Index Construction

Traditional commodity indices typically track the return performance of nearby commodity futures

contracts (e.g., “S&P GSCI ®” and “DJ-UBSCISM”)

– To maintain exposure to the futures contract that the relevant index intends to track, p , it is necessary to

“roll” from the front month contract (the first futures contract) before expiry, into the next nearby

contract (the second futures contract) during the “roll period.”

– Roll – when long a commodity index, the roll involves selling the first futures contract before expiry and

buying the second futures contract.

– Roll Period – the time window when exposure is rolled from the first futures contract into the second

futures contract.

– The “S&P GSCI®” and “DJ-UBSCISM” standard roll period is from the 5th to 9th business day each

month.

The return on a commodity index can be broken down into:

– Price movement of the futures contract.

– Roll yield (as explained on the next page).

– Hypothetical T-bill component (for total return indices).1

Note: S&P GSCI® is a trademark of Standard & Poor’s Financial Services LLC.

DJ-UBSCISM is a joint product of Dow Jones Indexes, a licensed trademark of CME Group Index Services LLC and UBS Securities LLC.

The techniques described above have considerations beyond the scope of this presentation; investors should consult legal, financial and tax advisors regarding their specific situation.

1 Total return indices include a T-bill component as they are intended to measure the collateralized returns accrued from holding and rolling futures contracts.

22 | Barclays Voyager Indices | 2012

Commodity Index Roll Yield

Roll yield is an important component of commodity index returns and will depend on the shape of the futures curve,

i.e., backwardated (downward sloping) or contango (upward sloping).

Price

Contango

Price

Backwardation

Time to expirTime to expiry y

Assuming the price and shape of the futures curve remain constant and a long position in a futures contract is rolled:

– In backwardation, a more expensive contract will be sold and a cheaper contract purchased, creating a positive

“roll yield” position in a contract

p yield , which can positively impact a long futures contract.

– In contango, a cheaper contract will be sold and a more expensive contract purchased, creating a negative “roll

yield”, which can negatively impact a long position in a futures contract.

23 | Barclays Voyager Indices | 2012

Commodity Index Roll Yield

A spot index tracks the price return (changes in the price of the relevant futures contract) and is a theoretical, noninvestable

index.

An excess return index tracks the returns accrued from holding and rolling commodity futures.

A i f tidi d t idi d ttthi ttht iti ti comparison of spot indices and excess return indices can demonstrate the impact that a positive or negative roll

yield can have on a long position.

Roll yield is determined by the difference in the excess return and spot return indices for each individual commodity.

“Front-end bias”

The front-end of the futures curve for a commodity has historically held the highest number of outstanding contracts (i.e.

the first or second futures contract).

– A large amount of passive money tracks the benchmark indices (traditional commodity indices); potentially greater than

$150bn.1

– Due to the transparency of index rules, the prices of certain commodities can be impacted during the roll period.

The front-end has historically been the steepest part of the futures curve and therefore where roll yield is most significant.

– For contango markets, investing further out on the curve may allow investors to potentially mitigate the effect of negative

roll yield.

Th f t d h hi t i ll b th t l til t f th The front-end has historically been the most volatile part of the futures curve.

– The front-end is the part of the curve that has historically been the most exposed to fundamental supply and demand

shocks.

Certain Risk Considerations

26 | Barclays Voyager Indices | 2012

Certain Risk Considerations

The Alpha Signal Test May be Ineffective, Producing Returns that Underperform the Relevant Reference Index, and May Cause the Voyager Product to Decrease

in Price:

Voyager Products are proprietary indices designed to reflect the returns available through the application of the Voyager signal to various commodities futures

contracts included in commodities indices. The application of the Voyager signal seeks to outperform the relevant reference index through a dynamic allocation

mechanism that alternates between (i) long and (ii) long and short positions in various underlying commodities futures contracts based on market trends in such

contracts based on historical and hypothetical historical pricing data. However, there can be no guarantee that the application of the Voyager signal will succeed

in these objectives. The Voyager signal may not accurately predict market trends in a commodities futures contract, and an allocation to such futures contract

may not be optimal and may result in a lower index level. If the Voyager signal proves to be ineffective, then an investment in the Voyager Product may

underperform a corresponding investment in instruments linked to other commodity indices, possibly by a substantial margin

Market Risk:

h d l k d d d l h h d l The return on structured investments linked to products or indices utilizing the Voyager methodology (“ Structured Investments”) is dependant on movements in

the level, value and price of such index or product (each a “Voyager Product”). Thus, changes in the level of any Voyager Product will determine the amount

payable on the Structured Investment. If a Voyager Product declines or remains unchanged, the return on the Structured Investment may be affected

The investor should be willing to hold the Structured Investment until maturity. If the investor sells the Structured Investment before maturity, the investor may

have to do so at a substantial discount from the issue price, and as a result, the investor may suffer substantial losses. The price, if any, at which the investor will

be able to sell the Structured Investment prior to maturity may be substantially less than the amount originally invested in the Structured Investment, depending

upon, the level of the Voyager Product at the time of the sale

Credit of Issuer:

The types of Structured Investments 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 Structured Investments, 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 Structured Investments 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 Structured Investments

Past Performance:

Hypothetical historical and historical results are not indicative of future performance of any Voyager Product or any related investment. Neither Barclays Bank

PLC nor Barclays Inc. makes any representation, assurances or guarantees that an investment in a Structured Investment will achieve returns consistent with

historical or hypothetical historical results

Liquidity:

There may be little or no secondary market for the Structured Investments. Barclays Inc. and other affiliates of Barclays Bank PLC intend to engage in limited

purchase and resale transactions. 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 this

product. If the investor sells the Structured Investments prior to maturity, the investor may have to sell them at a substantial loss. The investor should be willing

to hold the Structured Investments to maturity

27 | Barclays Voyager Indices | 2012

Certain Risk Considerations

Price Volatility:

Movements in the level of any Voyager Product or such Product’s 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 level of the

Voyager Product will rise or fall during the term of the Structured Investments. Changes in the level will determine the payment at maturity on the Structured

Investments. We cannot guarantee that these changes will be beneficial to the investor, and therefore the return at maturity may be adversely affected. Any

payment on the Structured Investments is subject to the creditworthiness of the Issuer

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 the issuer’s obligations under the Structured

Investments through one or more of the issuer’s affiliates. As a result, the price, if any, at which Barclays Inc. and other affiliates of Barclays Bank PLC will be

willing to purchase Structured Investments from you in secondary market transactions will likely be lower than the original issue price, and any sale prior to the

d ld l b ll ThS dI d d b h maturity date could result in a substantial loss to you. The Structured Investments are not designed to be short-term trading instruments. Accordingly, you

should be able and willing to hold your Structured Investments to maturity

Potential Conflicts:

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 and as index sponsor. 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

Many Economic and Market Factors Will Impact the Value of the Structured Investments:

In addition to the level of a Voyager Product on any day, the 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 Voyager Product 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; and

– the creditworthiness of the issuer, including actual or anticipated downgrades in the credit ratings of Barclays Bank PLC

Sales Through Barclays Wealth:

Barclays Wealth and Investment Management (“Barclays Wealth”), the wealth management division of Barclays Bank PLC, may arrange for the sale of the

Structured Investments to certain clients. The role of Barclays Wealth as a provider of certain services to such customers and as agent for Barclays Bank PLC, as

the case may be, in connection with the distribution of the Structured Investments to investors may create a potential conflict of interest, which may be adverse

to such clients. Barclays Wealth is acting solely as agent for Barclays Bank PLC, as the case may be. If you are considering whether to invest in the Structured

Investments through Barclays Wealth, we strongly urge you to seek independent financial and investment advice to assess the merits of such investment
