JO iPath Series B Bloomberg Coffee Subindex TR ETN

PRICING SUPPLEMENT SUMMARY

The following is a summary of terms of five series of iPath ^® Exchange Traded Notes (the “ ETNs ”) that are linked to a leveraged participation in the inverse performance of one of the S&P 500 ^® Total Return (the “ S&P 500 ”), the Russell 1000 ^® Total Return Index (the “ Russell 1000 Index ”), the Russell 2000 ^® Total Return Index (the “ Russell 2000 Index ” and, together with the Russell 1000 Index, the “ Russell Indices ”), the MSCI EAFE ^® Net Total Return Index (the “ EAFE Index ”) or the MSCI Emerging Markets Net Total Return Index (the “ EM Index ” and, together with the EAFE Index, the “ MSCI Indices ”), as well as a discussion of risks and other considerations you should take into account when deciding whether to invest in the ETNs. The information in this section is qualified in its entirety by the more detailed explanations set forth elsewhere in this pricing supplement and the accompanying prospectus and prospectus supplement. References to the “prospectus” mean our accompanying prospectus, dated August 31, 2010, and references to the “prospectus supplement” mean our accompanying prospectus supplement, dated May 27, 2011, which supplements the prospectus.

We may, without your consent, create and issue additional securities having the same terms and conditions as the ETNs. We may consolidate the additional securities to form a single class with the outstanding ETNs.

This section summarizes the following aspects of the ETNs:

What Are the ETNs and How Do They Work?

The ETNs are medium-term notes that are uncollateralized debt obligations of Barclays Bank PLC (the “ Issuer ”) and are linked to a leveraged participation in the inverse performance of one of the S&P 500, the Russell 1000 Index, the Russell 2000 Index, the EAFE Index or the EM Index (each an “ Index ” and collectively “ Indices ”) over the term of the ETNs. Accordingly, the ETNs generally appreciate in value as the level of the underlying Index decreases, provided such decrease is sufficient to offset the negative effect of the applicable daily investor fee and daily index borrow cost

Each series of ETNs seeks to approximate the returns that might be available to investors through leveraged short sales of the equity securities underlying the Index to which that series ETNs is linked. Short selling is the practice of selling assets (e.g., equity securities) that have been borrowed from a third party lender with the intention of buying identical assets back at a later date to return to such lender. By doing so, the short seller seeks to benefit from an anticipated decline in the value of the assets between the sale and the repurchase, as the short seller would pay less to repurchase the assets than he had originally received on selling the borrowed assets. Conversely, a short seller will incur a loss if the value of the assets rises between the sale and the repurchase. In order to seek to replicate this short-selling strategy, the terms of each series of ETNs provide that, on each valuation date, an amount equal to the closing indicative note value is notionally leveraged through the short sale of equity securities included in the Index underlying that series of ETNs in an amount equal to the short index amount on the applicable valuation date. Investors are thus considered to have notionally borrowed equity securities worth an amount equal to the applicable short index amount from the Issuer and to have notionally sold such equity securities on the initial valuation date for cash, which, together with the amount invested, represents a notional investment in cash equal to the applicable T-Bill amount on the applicable valuation date. During the term of your ETNs, the applicable T-Bill amount accrues daily interest for the benefit of the investor at a rate referred to as the “T-Bill rate”, which seeks to represent an amount of interest that short-selling investors might receive if they were to invest the proceeds of the sale of equity securities into an interest-bearing bank account. Over the same term of the ETNs, the applicable T-Bill amount is reduced by (1) an accrued daily investor fee for the benefit of the Issuer and (2) an accrued daily index borrow cost, which is a charge on the value of the equity securities

notionally sold short that seeks to represent the fees that a stock lender may charge a short-selling investor for lending the equity securities underlying the relevant Index for the term of the ETNs. Upon maturity or redemption, the equity securities underlying the relevant Index are then notionally repurchased by investors at their then current value using the notional cash represented by the applicable T-Bill amount and such borrowed equity securities are notionally delivered back to the Issuer. The payment at maturity or redemption under the ETNs, therefore, generally represents the profit or loss that the investor would receive by applying a short-selling strategy, after taking into account, and making assumptions for, accrued interest and accrued fees or costs that are commonly present in such short-selling strategies. In order to mitigate the risk to the Issuer that the value of the ETNs equals a negative value, an automatic early termination of the ETNs is provided for under the automatic termination event provisions hereunder.

The Indices

The Indices are as follows (for additional information on each Index, please see the section entitled “The Indices” in this pricing supplement):

The S&P 500 is calculated, maintained and published by Standard & Poor’s Financial Services LLC (“ S&P ”). The Russell Indices were developed by Frank Russell Company (“ Russell ”) and are calculated, maintained and published by Russell. The MSCI Indices are part of the “MSCI Global Investable Market Indices” calculated and maintained by MSCI, Inc. (“ MSCI ”). In this pricing supplement, we refer to S&P, Russell and MSCI collectively as the “ index sponsors ”.

Inception, Issuance and Maturity

The inception date is November 29, 2010. The ETNs were first issued on December 2, 2010, and are due on November 30, 2020.

Payment at Maturity

If you hold your ETNs to maturity, you will receive a cash payment in U.S. dollars at maturity in an amount equal to the closing indicative note value of your ETNs on the final valuation date.

Payment Upon Optional Redemption

Up to the valuation date immediately preceding the final valuation date and subject to the occurrence of an intervening automatic termination event and to certain other restrictions, you may elect to redeem your ETNs on any optional redemption date during the term of the ETNs, provided that you present at least 25,000 ETNs of the same series for redemption or your broker or other financial intermediary (such as a bank or other financial institution not required to register as a broker-dealer to engage in securities transactions) bundles your ETNs for redemption with those of other investors to reach this minimum. If you choose to redeem your ETNs, you will receive a cash payment in U.S. dollars on the applicable optional redemption date, for each ETN, in an amount equal to the closing indicative note value of your ETNs on the applicable valuation date.

Payment Upon the Occurrence of an Automatic Termination Event

We will automatically redeem a series of ETNs (in whole only, but not in part) if, on any calendar day prior to or on the final valuation date, the intraday indicative note value of that series is less than or equal to the applicable automatic termination level. We will redeem your ETNs on the automatic redemption date and deliver a notice of redemption to The Depository Trust Company (“ DTC ”) in the form attached as Annex C specifying such date. Upon such redemption, you will receive a cash payment in U.S. dollars equal to the automatic redemption value per ETN.

The “ closing indicative note value ” per ETN for each series of ETNs on the initial valuation date will equal the relevant principal amount per ETN. On any subsequent calendar day until maturity or redemption of the relevant series of ETNs, the closing indicative note value per ETN for each series of ETNs will equal (a) the applicable T-Bill amount on such calendar day minus (b) the applicable short index amount on such calendar day; provided that if such calculation results in a negative value, the closing indicative note value will be $0. The closing indicative note value will be published by NYSE Arca on each valuation date under the following ticker symbols: S&P 500 ETNs—SFSA.RDNV; Russell 1000 ETNs—ROSA.RDNV; Russell 2000 ETNs—RTSA.RDNV; MSCI EAFE ETNs—MFSA.RDNV; MSCI EM ETNs—EMSA.RDNV.

As a result of the occurrence of an automatic termination event on September 7, 2012 Barclays Bank PLC will automatically redeem its iPath ^® Short Extended Russell 1000 ^® TR Index ETNs and its iPath ^® Short Extended S&P 500 ^® TR Index ETNs. Each series of ETNs will be redeemed (in whole, but not in part) on September 14, 2012, the date which is five business days after the automatic termination date, and the payment upon redemption for each series of ETNs will be a cash payment in U.S. dollars equal to the relevant automatic redemption value for each series of ETNs on September 7, 2012, determined as described this pricing supplement.

As a result of the occurrence of an automatic termination event on September 13, 2012 Barclays Bank PLC will automatically redeem its iPath ^® Short Extended Russell 2000 ^® TR Index ETNs. The ETNs will be redeemed (in whole, but not in part) on September 20, 2012, the date which is five business days after the automatic termination date, and the payment upon redemption for each series of ETNs will be a cash payment in U.S. dollars equal to the relevant automatic redemption value for each series of ETNs on September 13, 2012, determined as described this pricing supplement.

The “ T-Bill amount ” per ETN for a series of ETNs on the initial valuation date will equal the principal amount per ETN for such series plus the applicable short index amount on the initial valuation date, which sum equals $200 per ETN for the S&P 500 ETNs and each series of the Russell ETNs and $300 per ETN for each series of the MSCI ETNs. On any subsequent calendar day until maturity or redemption of the relevant series of ETNs, the T-Bill amount per ETN for a series of ETNs will equal (a) the applicable T-Bill amount on the immediately preceding calendar day plus (b) the applicable daily interest minus (c) the applicable daily investor fee minus (d) the applicable daily index borrow cost. The T-Bill amount will be published by NYSE Arca on each valuation date under the following ticker symbols: S&P 500 ETNs—SFSA.TBNV; Russell 1000 ETNs—ROSA.TBNV; Russell 2000 ETNs—RTSA.TBNV; MSCI EAFE ETNs—MFSA.TBNV; MSCI EM ETNs—EMSA.TBNV.

The “ short index amount ” per ETN for a series of ETNs on the initial valuation date will equal the applicable initial leverage factor times the principal amount per ETN for such series, which product equals $150 per ETN for the S&P 500 ETNs and each series of the Russell ETNs and $200 per ETN for each series of the MSCI ETNs. On any subsequent calendar day until maturity or redemption of the relevant series of ETNs, the short index amount per ETN for each series of ETNs will equal the product of (a) the applicable short index amount on the initial valuation date times (b) the applicable index performance factor on such calendar day. The short index amount will be published by NYSE Arca on each valuation date under the following ticker symbols: S&P 500 ETNs—SFSA.IXNV; Russell 1000 ETNs—ROSA.IXNV; Russell 2000 ETNs—RTSA.IXNV; MSCI EAFE ETNs—MFSA.IXNV; MSCI EM ETNs—EMSA.IXNV.

The “ initial leverage factor ” will equal (a) 3, with respect to the S&P 500 ETNs and each series of the Russell ETNs and (b) 2, with respect to each series of the MSCI ETNs.

The “ index performance factor ” for each series of ETNs will equal 1 on the initial valuation date. On any subsequent calendar day until maturity or redemption of the relevant series of ETNs, the index performance factor for each series of ETNs will equal (a) the closing level of the Index to which those ETNs are linked on such calendar day (or, if such a calendar day is not an index business day, the closing level of the relevant Index on the immediately preceding index business day) divided by (b) the closing level of such underlying Index on the initial valuation date.

The “ daily interest ” per ETN for each series of ETNs on the initial valuation date will equal $0. On any subsequent calendar day until maturity or redemption of the relevant series of ETNs, the daily interest per ETN for each series of ETNs will equal the product of (a) the applicable T-Bill amount on the immediately preceding calendar day times (b) the T-Bill rate divided by (c) 365. Because the daily interest is calculated and added to the T-Bill amount on a daily basis, the net effect of the daily interest accrues over time.

The “T-Bill rate” will equal the most recent weekly investment rate for 28-day U.S. Treasury bills effective on the preceding business day in New York City. The weekly investment rate for 28-day U.S. Treasury bills is generally announced by the U.S. Treasury on each Monday; on any Monday that is not a business day in New York City, the rate prevailing on the immediately preceding business day in New York City will apply. The most recent weekly investment rate for 28-day U.S. Treasury bills is published on Bloomberg under the ticker symbol “USB4WIR”. The T-Bill rate is expressed as a percentage.

The “ daily investor fee ” per ETN for each series of ETNs on the initial valuation date will equal $0. On any subsequent calendar day until maturity or redemption of the relevant series of ETNs, the daily investor fee per ETN for each series of ETNs will equal the product of (a) the applicable closing indicative note value on the immediately preceding calendar day times (b) the applicable fee rate divided by (c) 365. Because the daily investor fee is calculated as part of the T-Bill amount through which it is subtracted from the closing indicative note value on a daily basis, the net effect of the daily investor fee accumulates over time and is subtracted at a rate per year equal to the applicable fee rate specified below.

The “ fee rate ” for each series of ETNs is as follows: 0.35% for the S&P 500 ETNs; 0.50% for each series of Russell ETNs; and 0.80% for each series of MSCI ETNs.

The “ daily index borrow cost ” per ETN for each series of ETNs on the initial valuation date will equal $0. On any subsequent calendar day until maturity or redemption of the relevant series of ETNs, the daily index borrow cost per ETN for each series of ETNs will equal the product of (a) the applicable short index amount on the immediately preceding calendar day times (b) the applicable borrow rate divided by (c) 365. Because the daily index borrow cost is calculated as part of the T-Bill Amount and is subtracted from the closing indicative note value on a daily basis, the net effect of the daily index borrow cost accrues over time at a rate per year equal to the borrow rate.

The “ borrow rate ” for each series of ETNs is as follows: 0.50% for the S&P 500 ETNs; 1.00% for the Russell 1000 ETNs; 1.75% for the Russell 2000 ETNs; 1.75% for the MSCI EAFE ETNs; and 2.50% for the MSCI EM ETNs.

An “ optional redemption date ” for each series of ETNs is the third business day following each valuation date (other than the final valuation date). The final optional redemption date will be the third business day following the valuation date that is immediately prior to the final valuation date.

The “ automatic termination level ” for each series of ETNs is as follows: For the S&P 500 ETNs and the Russell 1000 ETNs, $10.00, or 20.00% of the principal amount of such ETNs; for the Russell 2000 ETNs, $15.00, or 30.00% of the principal amount of such ETNs; for the MSCI EAFE ETNs, $37.50, or 37.50% of the principal amount of such ETNs; and for the MSCI EM ETNs, $45.00, or 45.00% of the principal amount of such ETNs.

An “ automatic termination date ” for each series of ETNs is any calendar day on which an automatic termination event occurs.

An “ automatic redemption date ” for each series of ETNs will be the fifth business day following the automatic termination date; provided that if calculation of the automatic redemption value is postponed as a result of a market disruption event, the automatic redemption date will be the fifth business day after the automatic redemption value is calculated.

The “ automatic redemption value ” for each series of ETNs will be determined by the calculation agent, in its sole discretion, acting in good faith and in a commercially reasonable manner, using the latest publicly available quotations for the intraday prices of the relevant equity securities underlying the Index to which such series is linked that are available as soon as practicable following the occurrence of an automatic termination event. The calculation agent will approximate the applicable intraday index performance factor on the basis of such quotations and calculate, in the manner described below under “intraday indicative note value”, a corresponding intraday indicative note value, which shall be deemed to be the automatic redemption value. The automatic redemption value shall not be greater than the applicable automatic termination level for each ETN and shall not be less than $0 per ETN.

The “ intraday indicative note value ” per ETN for each series of ETNs at any point in time will equal (a) the applicable T-Bill amount on the immediately preceding calendar day minus (b) the applicable intraday short index amount; provided that if such calculation results in a negative value, the intraday indicative note value will be $0. During the hours on which trading is generally conducted on the NYSE Arca, the intraday indicative note value will be published by NYSE Arca every 15 seconds under the following ticker symbols: SFSA.IV for the S&P 500 ETNs; ROSA.IV for the Russell 1000 ETNs; RTSA.IV for the Russell 2000 ETNs; MFSA.IV for the MSCI EAFE ETNs; and EMSA.IV for the MSCI EM ETNs. As the intraday indicative note value is calculated using the T-Bill amount through the close of the immediately preceding calendar day, the intraday indicative note value calculated at any given time will not reflect the applicable daily investor fee, daily index borrow cost and daily interest that may have accrued over the course of the calendar day on which such intraday indicative note value is calculated.

The “ intraday short index amount ” per ETN for each series of ETNs will equal the product of (a) the applicable initial leverage factor times (b) the principal amount per ETN for such series times (c) the applicable intraday index performance factor.

The “ intraday index performance factor ” for each series of ETNs will equal (a) the most recently published level of the Index to which those ETNs are linked divided by (b) the closing level of such Index on the initial valuation date.

A “ business day ” with respect to any series of ETNs means a Monday, Tuesday, Wednesday, Thursday or Friday that is neither a day on which banking institutions in New York City or London, as applicable, generally are authorized or obligated by law, regulation, or executive order to close.

A “ valuation date ” with respect to any series of ETNs means each trading day from November 29, 2010 to November 24, 2020, subject to postponement as a result of market disruption events, such postponement not to exceed five trading days. We refer to November 29, 2010 as the “ initial valuation date ” and November 24, 2020 as the “ final valuation date ”.

A “ trading day ” with respect to any series of ETNs is a day on which (1) it is a business day in New York City, (2) trading is generally conducted on the NYSE Arca, and (3) trading is generally conducted on the markets on which the components of the Index to which that series of ETNs is linked are traded, in each case as determined by the calculation agent in its sole discretion.

An “ index business day ” for each Index is a day on which the index sponsor of such Index publishes a closing value for such Index.

We will not pay you interest during the term of the ETNs.

For a further description of how your payment at maturity will be calculated, see “Hypothetical Examples” and “Specific Terms of the ETNs” in this pricing supplement.

Because your investment in the ETNs is linked to the inverse performance of the Index underlying your ETNs, an increase in the level of the underlying Index will have a negative effect on the repayment amount, whereas a decrease in the level of the underlying Index will have a positive effect on the repayment amount. Because your investment in the ETNs is leveraged, any increase in the level of the applicable underlying Index will result in a significantly greater decrease in the repayment amount, and you may receive less than your original investment in the ETNs at maturity or upon redemption. Moreover, because the applicable daily investor fee and daily index borrow cost may substantially reduce the amount of your return at maturity or upon redemption, the level of the Index underlying your ETNs must decrease significantly in order for you to receive at least the principal amount of your investment at maturity or upon redemption. If the level of the applicable underlying Index increases or does not decrease sufficiently to offset the negative effect of the applicable daily investor fee and daily index borrow cost, you will receive less than the principal amount of your investment at maturity or upon redemption.

If the level of the Index underlying your ETNs increases sufficiently to trigger an automatic termination event, your ETNs will be automatically redeemed at the automatic redemption value. Following the calculation of the automatic redemption value, you will not benefit from any subsequent decrease in the applicable Index level.

How Do You Redeem Your ETNs?

To redeem your ETNs, you must instruct your broker or other person through whom you hold your ETNs to take the following steps:

Different brokerage firms may have different deadlines for accepting instructions from their customers. Accordingly, you should consult the brokerage firm through which you own your interest in the ETNs in respect of such deadlines. If we do not receive your notice of redemption by 4:00 p.m., New York City time, or your confirmation of redemption by 5:00 p.m., New York City time, on the business day prior to the applicable valuation date, your notice will not be effective, and we will not redeem your ETNs on the applicable optional redemption date. Any

redemption instructions for which we (or our affiliate) receive a valid confirmation in accordance with the procedures described above will be irrevocable. Additionally, if an automatic termination event occurs between the time at which you deliver a notice of redemption to us and the close of business on the applicable valuation date, your notice of redemption will be deemed ineffective and your ETNs will be automatically redeemed on the automatic redemption date at an amount equal to the automatic redemption value.

What Are Some of the Risks of the ETNs?

An investment in the ETNs involves risks. Some of these risks are summarized here, but we urge you to read the more detailed explanation of risks in “Risk Factors” in this pricing supplement.

What Are the Tax Consequences?

Absent a change in law or an administrative or judicial ruling to the contrary, pursuant to the terms of the ETNs, by purchasing the ETNs, you agree to treat the ETNs for all U.S. federal income tax purposes as a pre-paid executory contract with respect to the relevant Index. If the ETNs are so treated, you should generally recognize capital gain or loss upon the sale, redemption or maturity of your ETNs in an amount equal to the difference between the amount you receive at such time and your tax basis in the ETNs.

The U.S. federal income tax consequences of your investment in the ETNs are uncertain. In the opinion of our counsel, Sullivan & Cromwell LLP, the S&P 500 ETNs and the Russell 1000 ETNs should each be treated as described above. In the opinion of our counsel, Sullivan & Cromwell LLP, it would be reasonable to treat each of the Russell 2000 ETNs, the MSCI EAFE ETNs and the MSCI EM ETNs as described above. However, it is possible that the Internal Revenue Service may assert an alternative treatment. Because of this uncertainty, we urge you to consult your own tax advisor as to the tax consequences of your investment in the ETNs.

For a more complete discussion of the U.S. federal income tax consequences of your investment in the ETNs, including possible alternative treatments for your ETNs, see “Material U.S. Federal Income Tax Considerations” below.
