Issuer Free Writing Prospectus Filed Pursuant to Rule 433 Registration Statement No. 333-190038 October 27, 2015 Barclays Bank PLC Trigger Performance Securities

Linked to the Vanguard FTSE Emerging Markets ETF due on or about November 30, 2020

Investment Description

Trigger Performance Securities (the “Securities”) are unsecured and unsubordinated debt obligations issued by Barclays Bank PLC (the “Issuer”) with returns linked to the performance of the Vanguard FTSE Emerging Markets ETF (the “Underlying Equity”). If the Equity Return is positive, the Issuer will repay the principal amount of the Securities at maturity plus pay a return equal to the Equity Return times the Participation Rate, which will be set on the Trade Date and will be equal to a percentage between 126.00% and 136.00%. If the Equity Return is zero or negative and the Final Price is greater than or equal to the Trigger Price (75% of the Initial Price), the Issuer will repay the principal amount of the Securities at maturity. However, if the Final Price is less than the Trigger Price, you will be exposed to the full decline in the Underlying Equity and the Issuer will repay less than the full principal amount of the Securities at maturity, if anything, resulting in a loss of principal that is proportionate to the negative Equity Return. Investing in the Securities involves significant risks. The Issuer will not pay any interest on the Securities. You may lose some or all of your principal. The Trigger Price is observed relative to the Final Price only on the Final Valuation Date, and the contingent repayment of principal applies only if you hold the Securities to maturity. Any payment on the Securities, including any repayment of principal, is subject to the creditworthiness of Barclays Bank PLC and is not guaranteed by any third party. If Barclays Bank PLC were to default on its payment obligations or become subject to the exercise of any U.K. Bail-in Power (as described on page FWP-3 of this free writing prospectus) by the relevant U.K. resolution authority, you might not receive any amounts owed to you under the Securities. See “Consent to U.K. Bail-in Power” in this free writing prospectus and “Risk Factors” in the accompanying prospectus addendum.

q Growth Potential: At maturity, the Securities participate in any positive returns of the Underlying Equity at the Participation Rate. If the Equity Return is negative, investors may be exposed to the full decline in the Underlying Equity at maturity. q Contingent Repayment of Principal at Maturity: If the Equity Return is zero or negative and the Final Price is greater than or equal to the Trigger Price, the Issuer will repay the principal amount at maturity. However, if the Final Price is less than the Trigger Price, the Issuer will repay less than the full principal amount at maturity, if anything, resulting in a loss of principal to investors that is proportionate to the negative Equity Return. The Trigger Price is observed relative to the Final Price only on the Final Valuation Date, and the contingent repayment of principal applies only if you hold the Securities to maturity. Any payment on the Securities, including any repayment of principal, is subject to the creditworthiness of Barclays Bank PLC.	Trade Date:	November 24, 2015

NOTICE TO INVESTORS: THE SECURITIES ARE SIGNIFICANTLY RISKIER THAN CONVENTIONAL DEBT INSTRUMENTS. THE ISSUER IS NOT NECESSARILY OBLIGATED TO REPAY THE FULL PRINCIPAL AMOUNT OF THE SECURITIES AT MATURITY, AND THE SECURITIES CAN HAVE THE FULL DOWNSIDE MARKET RISK OF THE UNDERLYING EQUITY. THIS MARKET RISK IS IN ADDITION TO THE CREDIT RISK INHERENT IN PURCHASING A DEBT OBLIGATION OF BARCLAYS BANK PLC. YOU SHOULD NOT PURCHASE THE SECURITIES IF YOU DO NOT UNDERSTAND OR ARE NOT COMFORTABLE WITH THE SIGNIFICANT RISKS INVOLVED IN INVESTING IN THE SECURITIES.

YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED UNDER “KEY RISKS” BEGINNING ON PAGE FWP-6 OF THIS FREE WRITING PROSPECTUS, “RISK FACTORS” BEGINNING ON PAGE S-6 OF THE PROSPECTUS SUPPLEMENT, “RISK FACTORS” BEGINNING ON PAGE PA-1 OF THE PROSPECTUS ADDENDUM AND “KEY RISKS” BEGINNING ON PAGE IS-2 OF THE INDEX SUPPLEMENT BEFORE PURCHASING ANY SECURITIES. EVENTS RELATING TO ANY OF THOSE RISKS, OR OTHER RISKS AND UNCERTAINTIES, COULD ADVERSELY AFFECT THE MARKET VALUE OF, AND THE RETURN ON, YOUR SECURITIES. YOU MAY LOSE SOME OR ALL OF THE PRINCIPAL AMOUNT OF THE SECURITIES. THE SECURITIES WILL NOT BE LISTED ON ANY SECURITIES EXCHANGE.

BY ACQUIRING THE SECURITIES, YOU ACKNOWLEDGE, AGREE TO BE BOUND BY AND CONSENT TO THE EXERCISE OF, ANY U.K. BAIL-IN POWER. SEE “CONSENT TO BAIL-IN POWER” ON PAGE FWP-3 OF THIS FREE WRITING PROSPECTUS.

Our SEC file number is 1-10257. References to “Barclays,” “Barclays Bank PLC,” “we,” “our” and “us” refer only to Barclays Bank PLC and not to its consolidated subsidiaries. In this document, “Securities” refers to the Trigger Performance Securities that are offered hereby, unless the context otherwise requires.

Additional Information Regarding Our Estimated Value of the Securities

The range of the estimated values of the Securities referenced above may not correlate on a linear basis with the range for the Participation Rate set forth in this free writing prospectus. We determined the size of the range for the Participation Rate based on prevailing market conditions, as well as the anticipated duration of the marketing period for the Securities. The final terms for the Securities will be determined on the date the Securities are initially priced for sale to the public (the “Trade Date”) based on prevailing market conditions on the Trade Date, and will be communicated to investors either orally or in a final pricing supplement.

Our internal pricing models take into account a number of variables and are based on a number of subjective assumptions, which may or may not materialize, typically including volatility, interest rates and our internal funding rates. Our internal funding rates (which are our internally published borrowing rates based on variables, such as market benchmarks, our appetite for borrowing and our existing obligations coming to maturity) may vary from the levels at which our benchmark debt securities trade in the secondary market. Our estimated value on the Trade Date is based on our internal funding rates. Our estimated value of the Securities might be lower if such valuation were based on the levels at which our benchmark debt securities trade in the secondary market.

Our estimated value of the Securities on the Trade Date is expected to be less than the initial issue price of the Securities. The difference between the initial issue price of the Securities and our estimated value of the Securities is expected to result from several factors, including any sales commissions expected to be paid to Barclays Capital Inc. or another affiliate of ours, any selling concessions, discounts, commissions or fees expected to be allowed or paid to non-affiliated intermediaries, the estimated profit that we or any of our affiliates expect to earn in connection with structuring the Securities, the estimated cost that we may incur in hedging our obligations under the Securities, and estimated development and other costs that we may incur in connection with the Securities.

Our estimated value on the Trade Date is not a prediction of the price at which the Securities may trade in the secondary market, nor will it be the price at which Barclays Capital Inc. may buy or sell the Securities in the secondary market. Subject to normal market and funding conditions, Barclays Capital Inc. or another affiliate of ours intends to offer to purchase the Securities in the secondary market but it is not obligated to do so.

Assuming that all relevant factors remain constant after the Trade Date, the price at which Barclays Capital Inc. may initially buy or sell the Securities in the secondary market, if any, and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed our estimated value on the Trade Date for a temporary period expected to be approximately eleven months after the initial issue date of the Securities because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the Securities and other costs in connection with the Securities that we will no longer expect to incur over the term of the Securities. We made such discretionary election and determined this temporary reimbursement period on the basis of a number of factors, including the tenor of the Securities and any agreement we may have with the distributors of the Securities. The amount of our estimated costs that we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the initial issue date of the Securities based on changes in market conditions and other factors that cannot be predicted.

We urge you to read the “Key Risks” beginning on page FWP-6 of this free writing prospectus.

You may revoke your offer to purchase the Securities at any time prior to the Trade Date. We reserve the right to change the terms of, or reject any offer to purchase, the Securities prior to their Trade Date. In the event of any changes to the terms of the Securities, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes in which case we may reject your offer to purchase.

Consent to U.K. Bail-in Power

Under the U.K. Banking Act 2009, as recently amended, the relevant U.K. resolution authority may exercise a U.K. Bail-in Power under certain conditions which, in summary, include that such authority determines that: (i) a relevant entity (such as the Issuer) is failing or is likely to fail, (ii) it is not reasonably likely that (ignoring the other stabilization powers under the U.K. Banking Act) any other action will be taken to avoid the entity’s failure, (iii) the exercise of the stabilization powers are necessary taking into account certain public interest considerations such as the stability of the U.K. financial system, public confidence in the U.K. banking system and the protection of depositors and (iv) the objectives of the resolution measures would not be met to the same extent by the winding up of the entity. Notwithstanding these conditions, there remains uncertainty regarding how the relevant U.K. resolution authority would assess these conditions in deciding whether to exercise any U.K. Bail-in Power. The U.K. Bail-in Power includes any statutory write-down and conversion power, which allows for the cancellation of all, or a portion, of any amounts payable on the Securities, including any repayment of principal and/or the conversion of all, or a portion, of any amounts payable on the Securities, including the repayment of principal, into shares or other securities or other obligations of ours or another person, including by means of a variation to the terms of the Securities. Accordingly, if any U.K. Bail-in Power is exercised you may lose all or a part of the value of your investment in the Securities or receive a different security, which may be worth significantly less than the Securities and which may have significantly fewer protections than those typically afforded to debt securities. Moreover, the relevant U.K. resolution authority may exercise its authority to implement the U.K. Bail-in Power without providing any advance notice to the holders of the Securities.

By your acquisition of the Securities, you acknowledge, agree to be bound by and consent to the exercise of, any U.K. Bail-in Power by the relevant U.K. resolution authority.

This is only a summary. For more information, please see “Key Risks—You May Lose Some or All of Your Investment If Any U.K. Bail-in Power Is Exercised by the Relevant U.K. Resolution Authority” in this free writing prospectus and the full definition of “U.K. Bail-in Power” as well as the risk factors in the accompanying prospectus addendum.

Key Risks

An investment in the Securities involves significant risks. Investing in the Securities is not equivalent to investing directly in the Underlying Equity, the component securities held by the Underlying Equity or the securities composing the Underlying Index (as defined under “Vanguard FTSE Emerging Markets ETF” below). Some of the risks that apply to an investment in the Securities are summarized below, but we urge you to read the more detailed explanation of risks relating to the Securities generally in the “Risk Factors” sections of the prospectus supplement and the prospectus addendum. You should reach an investment decision only after you have carefully considered with your advisors the suitability of an investment in the Securities in light of your particular circumstances.

¨ You Risk Losing Some or All of Your Principal — The Securities differ from ordinary debt securities in that the Issuer will not necessarily repay the full principal amount of the Securities at maturity. The Issuer will pay you the principal amount of your Securities only if the Final Price is greater than or equal to the Trigger Price and will make such payment only at maturity. If the Final Price is less than the Trigger Price, you will be exposed to the full negative Equity Return and the Issuer will repay less than the full principal amount of the Securities at maturity, if anything, resulting in a loss of the principal amount that is proportionate to the decline of the Underlying Equity from the Trade Date to the Final Valuation Date. Accordingly, you may lose some or all of your principal.

¨ Contingent Repayment of Principal Applies Only if You Hold the Securities to Maturity — You should be willing to hold your Securities to maturity. The market value of the Securities may fluctuate between the date you purchase them and the Final Valuation Date. If you are able to sell your Securities prior to maturity in the secondary market, if any, you may have to sell them at a loss relative to your initial investment even if at such time the price of the Underlying Equity is greater than the Trigger Price.

¨ The Participation Rate Applies Only if You Hold the Securities to Maturity — You should be willing to hold your Securities to maturity. If you are able to sell your Securities prior to maturity in the secondary market, if any, the price you receive likely will not reflect the full economic value of the Participation Rate or the Securities themselves, and the return you realize may be less than the product of the performance of the Underlying Equity and the Participation Rate and may be less than the Underlying Equity’s return itself, even if such return is positive. You can receive the full benefit of the Participation Rate only if you hold your Securities to maturity.

¨ Credit of Issuer — The Securities are unsecured and unsubordinated debt 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 Securities, including any repayment of principal, depends on the ability of Barclays Bank PLC to satisfy its obligations as they come due and is not guaranteed by any third party. As a result, the actual and perceived creditworthiness of Barclays Bank PLC may affect the market value of the Securities and, in the event Barclays Bank PLC were to default on its obligations, you might not receive any amount owed to you under the terms of the Securities.

¨ You May Lose Some or All of Your Investment If Any U.K. Bail-in Power Is Exercised by the Relevant U.K. Resolution Authority — Under the U.K. Banking Act 2009, as recently amended, the relevant U.K. resolution authority may exercise a U.K. Bail-in Power under certain conditions which, in summary, include that such authority determines that: (i) a relevant entity (such as the Issuer) is failing or is likely to fail, (ii) it is not reasonably likely that (ignoring the other stabilization powers under the U.K. Banking Act) any other action will be taken to avoid the entity’s failure, (iii) the exercise of the stabilization powers are necessary taking into account certain public interest considerations such as the stability of the U.K. financial system, public confidence in the U.K. banking system and the protection of depositors and (iv) the objectives of the resolution measures would not be met to the same extent by the winding up of the entity. Notwithstanding these conditions, there remains uncertainty regarding how the relevant U.K. resolution authority would assess these conditions in deciding whether to exercise any U.K. Bail-in Power. The U.K. Bail-in Power includes any statutory write-down and conversion power, which allows for the cancellation of all, or a portion, of any amounts payable on the Securities, including any repayment of principal and/or the conversion of all, or a portion, of any amounts payable on the Securities, including the repayment of principal, into shares or other securities or other obligations of ours or another person, including by means of a variation to the terms of the Securities. Accordingly, if any U.K. Bail-in Power is exercised you may lose all or a part of the value of your investment in the Securities or receive a different security, which may be worth significantly less than the Securities and which may have significantly fewer protections than those typically afforded to debt securities. Moreover, the relevant U.K. resolution authority may exercise its authority to implement the U.K. Bail-in Power without providing any advance notice to the holders of the Securities.

By your acquisition of the Securities, you acknowledge, agree to be bound by and consent to the exercise of, any U.K. Bail-in Power by the relevant U.K. resolution authority. The exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the Securities will not be a default or an Event of Default (as each term is defined in the indenture) and the trustee will not be liable for any action that the trustee takes, or abstains from taking, in either case, in accordance with the exercise of the U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the Securities. Accordingly, your rights as a holder of the Securities are subject to, and will be varied, if necessary, so as to give effect to, the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority. Please see “Consent to U.K. Bail-in Power” in this free writing prospectus and the risk factors in the accompanying prospectus addendum for more information.

¨ Owning the Securities Is Not the Same as Owning the Underlying Equity, the Component Securities Held by the Underlying Equity or the Securities Composing the Underlying Index — The return on your Securities may not reflect the return you would realize if you actually owned the Underlying Equity, the component securities held by the Underlying Equity or the securities composing the Underlying Index. As a holder of the Securities, you will not have voting rights or rights to receive dividends or other distributions or other rights that holders of the Underlying Equity, the component securities held by the Underlying Equity or the securities composing the Underlying Index would have.

¨ No Interest Payments — The Issuer will not make periodic interest payments on the Securities, and the return on the Securities is limited to the performance of the Underlying Equity from the Trade Date to the Final Valuation Date.

¨ Dealer Incentives — We, the Agents and affiliates of the Agents may act in various capacities with respect to the Securities. The Agents and various affiliates may act as a principal, agent or dealer in connection with the Securities. Such Agents, including the sales representatives of UBS Financial Services Inc., will derive compensation from the distribution of the Securities and such compensation may serve as an incentive to sell these Securities instead of other investments. We will pay compensation as specified on the cover of this

FWP-6

free writing prospectus to the Agents in connection with the distribution of the Securities, and such compensation may be passed on to affiliates of the Agents or other third party distributors.

¨ Limited Liquidity — The Securities will not be listed on any securities exchange. Barclays Capital Inc. and other affiliates of Barclays Bank PLC intend to offer to purchase the Securities in the secondary market but are not required to do so and may cease any such market making activities at any time. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Securities easily. Because other dealers are not likely to make a secondary market for the Securities, the price at which you may be able to trade your Securities is likely to depend on the price, if any, at which Barclays Capital Inc. and other affiliates of Barclays Bank PLC are willing to buy the Securities.

¨ Potential Conflicts — We and our affiliates play a variety of roles in connection with the issuance of the Securities, including acting as Calculation Agent and hedging our obligations under the Securities. In performing these duties, the economic interests of the Calculation Agent and other affiliates of ours are potentially adverse to your interests as an investor in the Securities.

¨ Potentially Inconsistent Research, Opinions or Recommendations by Barclays, UBS Financial Services Inc. or Their Respective Affiliates — Barclays, UBS Financial Services Inc. or their respective affiliates and agents may publish research from time to time on financial markets and other matters that may influence the value of the Securities, or express opinions or provide recommendations that are inconsistent with purchasing or holding the Securities. Any research, opinions or recommendations expressed by Barclays, UBS Financial Services Inc. or their respective affiliates or agents may not be consistent with each other and may be modified from time to time without notice. You should make your own independent investigation of the merits of investing in the Securities and the Underlying Equity.

¨ Potential Barclays Bank PLC Impact on Value — Trading or transactions by Barclays Bank PLC or its affiliates in the Underlying Equity, the component securities held by the Underlying Equity or the securities composing the Underlying Index and/or over-the-counter options, futures or other instruments with returns linked to the performance of the Underlying Equity, the component securities held by the Underlying Equity or the securities composing the Underlying Index may adversely affect the price of the Underlying Equity and, therefore, the market value of the Securities.

¨ The Payment at Maturity on Your Securities Is Not Based on the Price of the Underlying Equity at Any Time Other Than the Final Valuation Date —The Final Price and the Equity Return will be based solely on the closing price of the Underlying Equity on the Final Valuation Date (subject to adjustments as described in the prospectus supplement). Therefore, if the price of the Underlying Equity drops precipitously on the Final Valuation Date, the payment at maturity on your Securities that the Issuer pays you may be significantly less than it would otherwise have been had the payment at maturity been linked to the price of the Underlying Equity at a time prior to such drop. Although the price of the Underlying Equity on the maturity date or at other times during the life of your Securities may be higher than the price of the Underlying Equity on the Final Valuation Date, you will not benefit from the price of the Underlying Equity at any time other than the Final Valuation Date.

¨ Certain Features of the Underlying Equity Will Impact the Value of the Securities —The performance of the Underlying Equity will not fully replicate the performance of the Underlying Index, and the Underlying Equity may hold securities not included in the Underlying Index. The value of the Underlying Equity to which your Securities are linked is subject to:

¨ Management risk. This is the risk that the investment strategy for the Underlying Equity, the implementation of which is subject to a number of constraints, may not produce the intended results.

¨ Derivatives risk. The Underlying Equity may invest in derivatives, including forward contracts, futures contracts, options on futures contracts, options and swaps. A derivative is a financial contract, the value of which depends on, or is derived from, the value of an underlying asset such as a security or an index. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices, and thus the Underlying Equity’s losses, and, as a consequence, the losses of your Securities, may be greater than if the Underlying Equity invested only in conventional securities.

¨ The Underlying Equity May Underperform the Underlying Index —The performance of the Underlying Equity may not replicate the performance of, and may underperform, the Underlying Index. Unlike the Underlying Index, the Underlying Equity will reflect transaction costs and fees that will reduce its relative performance. Moreover, it is also possible that the Underlying Equity may not fully replicate or may, in certain circumstances, diverge significantly from the performance of the Underlying Index; for example, due to differences in trading hours between the Underlying Equity and the Underlying Index or due to other circumstances. During periods of market volatility, securities held by the Underlying Equity may be unavailable in the secondary market, market participants may be unable to calculate accurately the intraday net asset value per share of the Underlying Equity and the liquidity of the Underlying Equity may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares in the Underlying Equity. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of the Underlying Equity. As a result, under these circumstances, the market value of the Underlying Equity may vary substantially from the net asset value per share of the Underlying Equity. Because the payment due at maturity of your Securities is linked to the performance of the Underlying Equity and not the Underlying Index, the return on your Securities may be less than that of an alternative investment linked directly to the Underlying Index.

¨ Adjustments to the Underlying Equity or to the Underlying Index Could Adversely Affect the Value of the Securities —The investment adviser to the Underlying Equity seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the Underlying Index. Pursuant to its investment strategy or otherwise, an investment adviser may add, delete or substitute the components of the Underlying Equity. Any of these actions could adversely affect the value of the Underlying Equity and, consequently, the value of the Securities.

In addition, the publisher of the Underlying Index is responsible for calculating and maintaining the Underlying Index. The Underlying Index publisher may add, delete or substitute the securities composing that Underlying Index or make other methodological changes required by certain corporate events relating to the securities composing the Underlying Index, such as stock dividends, stock splits, spin-offs, rights offerings and extraordinary dividends, that could change the value of the Underlying Index. The Underlying Index publisher may also discontinue or suspend calculation or publication of the Underlying Index at any time. If this discontinuance or suspension

FWP-7

occurs, following the termination of the Underlying Equity, the Calculation Agent will have the sole discretion to substitute a successor fund that is comparable to the discontinued Underlying Equity, or if the Calculation Agent determines that no successor fund is available, to accelerate the maturity date of the Securities. If the Securities are accelerated, investors will not benefit from any potential appreciation of the Underlying Equity from the accelerated Maturity Date to the originally scheduled Maturity Date. Any of these actions could adversely affect the value of the Underlying Equity and, consequently, the value of the Securities.

For a description of the actions that may be taken by the Calculation Agent in the event that the publisher of the Underlying Index discontinues or suspends calculation of the Underlying Index or the Underlying Equity is liquidated or otherwise terminated, see “Reference Assets—Exchange-Traded Funds—Adjustments Relating to Securities with the Reference Asset Comprised of an Exchange-Traded Fund or Exchange-Traded Funds” in the prospectus supplement.

¨ The Underlying Equity Recently Completed a Process of Transition to a New Underlying Index and Will Soon Transition to Tracking Another New Underlying Index, Which Could Reduce the Performance of the Underlying Equity and Limit the Utility of Available Information about the Performance of the Underlying Equity — Until 2013, the Underlying Equity tracked the performance of the MSCI Emerging Markets Index (the “MXEF”) (see relevant disclosure under “Non-Proprietary Indices — Equity Indices — MSCI Indices” in the accompanying index supplement). In January 2013, The Vanguard Group, Inc. announced that the Underlying Equity was expected to adopt the FTSE Emerging Index as its new target index. In the first phase of the transition, which began on January 10, 2013, the Underlying Equity ceased tracking the MXEF, and began temporarily tracking the FTSE Emerging Transition Index, a “dynamic” index that gradually reduced its exposure to South Korean equities by approximately 4% each week for a period of 25 weeks, while proportionately adding exposure to securities of companies located in other countries based on their weightings in the new index. In the second phase of the transition, which commenced on June 28, 2013, the Underlying Equity ceased tracking the FTSE Emerging Transition Index and began tracking the FTSE Emerging Index. As a result of this transition, the historical performance of the Underlying Equity may be of limited use in evaluating the Underlying Equity’s past performance, as there is limited historical information at this time to reflect the Underlying Equity’s tracking of the FTSE Emerging Index. The Underlying Equity’s new Underlying Index could result in different investment returns (either lower or higher) or different levels of volatility than those of the former Underlying Index over any period of time.

Additionally, on June 2, 2015, The Vanguard Group, Inc. announced that the Underlying Equity will soon transition to track a new underlying index. According to The Vanguard Group, Inc., the transition to the new underlying index will take place over a period of approximately 12 months starting in the third or fourth quarter of 2015, with the Underlying Equity ceasing to track the FTSE Emerging Index and beginning to temporarily track the FTSE Emerging Markets All Cap China A Transition Index. By using this transition index, the Underlying Equity will move gradually from tracking the FTSE Emerging Index to tracking the FTSE Emerging Markets All Cap China A Inclusion Index. As part of the transition, China A-shares and small capitalization companies will gradually increase in weight by an equal amount after the third Friday each month over the 12-month period, while the weights of the stocks already in the index will be proportionately reduced. The FTSE Emerging Markets All Cap China A Inclusion Index is a market-capitalization weighted index representing the performance of large-, mid- and small-capitalization stocks in emerging markets. The principal differences between the FTSE Emerging Index and the FTSE Emerging Markets All Cap China A Inclusion Index are that the former represents the performance of large- and mid-capitalization companies in emerging markets, excluding China A-shares, whereas the latter also represents the performance of small-capitalization companies in emerging markets and includes China A-shares. As a result of this transition, the Underlying Equity will be exposed to risks associated with investing both in mainland China and in small-capitalization stocks.

Because the Underlying Equity will begin tracking indices that will include China A-shares, the Securities will become subject to increased risk exposure to Chinese incorporated companies that trade on either the Shanghai or Shenzhen stock exchange. Furthermore, in order to trade in China A-shares, a foreign investor must have access to a quota through a QFII or Renminbi QFII license holder. In order to trade in China A-shares, the Underlying Equity must obtain a quota from the Chinese regulator prior to investing and then must continue to apply for additional quotas to meet its investment needs. There is no guarantee that the Chinese regulator will continue to give the Underlying Equity any or all of its requested quotas. If the Underlying Equity were to be denied any or all of a requested trade quota, the Underlying Equity would likely have difficulty trading and valuing its China A-shares. Such circumstance would likely cause the Underlying Equity to have difficulty tracking the FTSE Emerging Markets All Cap China A Transition Index or FTSE Emerging Markets All Cap China A Inclusion Index, as applicable, and may adversely affect the value of the Underlying Equity and thus the value of the Securities.

During both the transition and final benchmark phases, the Underlying Equity will invest by sampling the relevant index, meaning that it will hold a broadly diversified collection of securities that, in the aggregate, approximates the full index in terms of key characteristics. To protect the Underlying Equity from the potential for harmful “front running” by traders, the exact timing of the index change and portfolio transition has not been disclosed to investors, but Vanguard expects the index change and portfolio transition to be complete by the end of 2016. As a result, you will not know in advance when the index tracked by the Underlying Equity changes. In addition, the addition of small-capitalization stocks and China A-Shares may adversely affect the performance of the Underlying Equity. Moreover, the historical performance of the Underlying Equity prior to this transaction will not reflect the contribution of small-capitalization stocks and China A-shares and investors in the Securities should bear this difference in mind when evaluating the historical data. See “Vanguard FTSE Emerging Markets ETF” below.

¨ Non-U.S. Securities Markets Risks —The component securities held by the Underlying Equity are issued by non-U.S. companies in non-U.S. securities markets. These securities may be more volatile and may be subject to different political, market, economic, exchange rate, regulatory and other risks. Also, the public availability of information concerning the issuers of the component securities held by the Underlying Equity will vary depending on their home jurisdiction and the reporting requirements imposed by their respective regulators. In addition, the issuers of the component securities held by the Underlying Equity may be subject to accounting, auditing and financial reporting standards and requirements that differ from those applicable to United States reporting companies.

¨ Risks Associated with Emerging Markets — An investment in the Securities linked to the Underlying Equity will involve risks not generally associated with investments which have no emerging market component. In particular, many emerging nations are undergoing rapid institutional change, involving the restructuring of economic, political, financial and legal systems. Regulatory and tax environments may be subject to change without review or appeal. Many emerging markets suffer from underdevelopment of capital markets and tax

FWP-8

regulation. The risk of expropriation and nationalization remains a threat. Guarding against such risks is made more difficult by low levels of corporate disclosure and unreliability of economic and financial data.

Moreover, as part of its transition to tracking the FTSE Emerging Markets All Cap China A Inclusion Index, the Underlying Equity will begin to hold shares that are traded on mainland Chinese exchanges (as distinct from exchanges in Hong Kong). Shares traded on mainland Chinese exchanges, referred to as A-shares, are subject to regulation by Chinese authorities, including regulations that limit the amount of shares that may be held by foreign investors. These regulations may adversely affect the price of A-shares. Trading in A-shares may be less liquid and subject to greater volatility, including as a result of actions by the Chinese government, than trading on international exchanges outside of mainland China.

¨ The Price of the Underlying Equity Is Subject to Currency Exchange Risk — Because the price of the Underlying Equity is related to the U.S. dollar value of the component securities held by the Underlying Equity, you will be exposed to the currency exchange rate risk with respect to each of the currencies in which such component securities trade. Exchange rate movements for a particular currency are volatile and are the result of numerous factors including the supply of, and the demand for, those currencies, as well as the relevant government policy, intervention or actions, but are also influenced significantly from time to time by political or economic developments, and by macroeconomic factors and speculative actions related to the relevant region. An investor’s net exposure will depend on the extent to which the currencies of the component securities strengthen or weaken against the U.S. dollar and the relative weight of each currency. If, taking into account such weighting, the dollar strengthens against the currencies of the component securities held by the Underlying Equity, the price of the Underlying Equity will be adversely affected and the payment at maturity on the Securities may be reduced.

Of particular importance to potential currency exchange risk are:

¨ existing and expected rates of inflation;

¨ existing and expected interest rate levels;

¨ the balance of payments; and

¨ the extent of governmental surpluses or deficits in the relevant countries and the United States.

All of these factors are in turn sensitive to the monetary, fiscal and trade policies pursued by the governments of various countries represented by the component securities held by the Underlying Equity and the United States and other countries important to international trade and finance.

¨ The Securities Are Subject to Small-Capitalization Companies Risk — The FTSE Emerging Markets All Cap China A Inclusion Index (the index that the Underlying Equity will soon begin tracking) may include stocks issued by companies with relatively small market capitalization and thus some of the component securities held by the Underlying Equity may include those small-capitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies, and therefore securities linked to the Underlying Equity may be more volatile than an investment linked to a fund that holds only component securities issued by large-capitalization companies. Stock prices of small-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business and economic developments. In addition, small-capitalization companies are typically less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Small-capitalization companies are often subject to less analyst coverage and may be in early, and less predictable, periods of their corporate existences. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products.

¨ Many Economic and Market Factors Will Impact the Value of the Securities — In addition to the price of the Underlying Equity on any day, the value of the Securities 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 Underlying Equity and the component securities held by the Underlying Equity;

¨ the time to maturity of the Securities;

¨ the market price and dividend rate on the Underlying Equity;

¨ interest and yield rates in the market generally;

¨ supply and demand for the Securities;

¨ a variety of economic, financial, political, regulatory and judicial events;

¨ the exchange rates relative to the U.S. dollar with respect to each of the currencies in which the component securities held by the Underlying Equity trade; and

¨ our creditworthiness, including actual or anticipated downgrades in our credit ratings.

¨ The Estimated Value of Your Securities Is Expected to Be Lower Than the Initial Issue Price of Your Securities — The estimated value of your Securities on the Trade Date is expected to be lower, and may be significantly lower, than the initial issue price of your Securities. The difference between the initial issue price of your Securities and the estimated value of the Securities is expected as a result of certain factors, such as any sales commissions expected to be paid to Barclays Capital Inc. or another affiliate of ours, any selling concessions, discounts, commissions or fees expected to be allowed or paid to non-affiliated intermediaries, the estimated profit that we or any of our affiliates expect to earn in connection with structuring the Securities, the estimated cost that we may incur in hedging our obligations under the Securities, and estimated development and other costs that we may incur in connection with the Securities.

FWP-9

¨ The Estimated Value of Your Securities Might Be Lower if Such Estimated Value Were Based on the Levels at Which Our Debt Securities Trade in the Secondary Market — The estimated value of your Securities on the Trade Date is based on a number of variables, including our internal funding rates. Our internal funding rates may vary from the levels at which our benchmark debt securities trade in the secondary market. As a result of this difference, the estimated values referenced above might be lower if such estimated values were based on the levels at which our benchmark debt securities trade in the secondary market. Also, this difference in funding rate as well as certain factors, such as sales commissions, selling concessions, estimated costs and profits mentioned below, reduces the economic terms of the Securities to you.

¨ The Estimated Value of the Securities Is Based on Our Internal Pricing Models, Which May Prove to Be Inaccurate and May Be Different from the Pricing Models of Other Financial Institutions — The estimated value of your Securities on the Trade Date is based on our internal pricing models, which take into account a number of variables and are based on a number of subjective assumptions, which may or may not materialize. These variables and assumptions are not evaluated or verified on an independent basis. Further, our pricing models may be different from other financial institutions’ pricing models and the methodologies used by us to estimate the value of the Securities may not be consistent with those of other financial institutions that may be purchasers or sellers of Securities in the secondary market. As a result, the secondary market price of your Securities may be materially different from the estimated value of the Securities determined by reference to our internal pricing models.

¨ The Estimated Value of Your Securities Is Not a Prediction of the Prices at Which You May Sell Your Securities in the Secondary Market, if Any, and Such Secondary Market Prices, if Any, Will Likely Be Lower Than the Initial Issue Price of Your Securities and May Be Lower Than the Estimated Value of Your Securities — The estimated value of the Securities will not be a prediction of the prices at which Barclays Capital Inc., other affiliates of ours or third parties may be willing to purchase the Securities from you in secondary market transactions (if they are willing to purchase, which they are not obligated to do). The price at which you may be able to sell your Securities in the secondary market at any time will be influenced by many factors that cannot be predicted, such as market conditions, and any bid and ask spread for similar sized trades, and may be substantially less than our estimated value of the Securities. Further, as secondary market prices of your Securities take into account the levels at which our debt securities trade in the secondary market, and do not take into account our various costs related to the Securities such as fees, commissions, discounts, and the costs of hedging our obligations under the Securities, secondary market prices of your Securities will likely be lower than the initial issue price of your Securities. As a result, the price at which Barclays Capital Inc., other affiliates of ours or third parties may be willing to purchase the Securities from you in secondary market transactions, if any, will likely be lower than the price you paid for your Securities, and any sale prior to the maturity date could result in a substantial loss to you.

¨ The Temporary Price at Which We May Initially Buy the Securities in the Secondary Market and the Value We May Initially Use for Customer Account Statements, if We Provide Any Customer Account Statements at All, May Not Be Indicative of Future Prices of Your Securities — Assuming that all relevant factors remain constant after the Trade Date, the price at which Barclays Capital Inc. may initially buy or sell the Securities in the secondary market (if Barclays Capital Inc. makes a market in the Securities, which it is not obligated to do) and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed our estimated value of the Securities on the Trade Date, as well as the secondary market value of the Securities, for a temporary period after the initial issue date of the Securities. The price at which Barclays Capital Inc. may initially buy or sell the Securities in the secondary market and the value that we may initially use for customer account statements may not be indicative of future prices of your Securities. Please see “Additional Information Regarding Our Estimated Value of the Securities” on page FWP-2 for further information.

¨ We and Our Affiliates May Engage in Various Activities or Make Determinations That Could Materially Affect Your Securities in Various Ways and Create Conflicts of Interest — We and our affiliates establish the offering price of the Securities for initial sale to the public, and the offering price is not based upon any independent verification or valuation. Additionally, the role played by Barclays Capital Inc., as a dealer in the Securities, could present it with significant conflicts of interest with the role of Barclays Bank PLC, as issuer of the Securities. For example, Barclays Capital Inc. or its representatives may derive compensation or financial benefit from the distribution of the Securities and such compensation or financial benefit may serve as an incentive to sell these Securities instead of other investments. We may pay dealer compensation to any of our affiliates acting as agents or dealers in connection with the distribution of the Securities. Furthermore, we and our affiliates make markets in and trade various financial instruments or products for their own accounts and for the account of their clients and otherwise provide investment banking and other financial services with respect to these financial instruments and products. These financial instruments and products may include securities, instruments or assets that may serve as the underliers or constituents of the underliers of the Securities. Such market making, trading activities, other investment banking and financial services may negatively impact the value of the Securities. Furthermore, in any such market making, trading activities, and other services, we or our affiliates may take positions or take actions that are inconsistent with, or adverse to, the investment objectives of the holders of the Securities. We and our affiliates have no obligation to take the needs of any buyer, seller or holder of the Securities into account in conducting these activities.

¨ The U.S. Federal Income Tax Consequences of an Investment in the Securities Are Uncertain — There is no direct legal authority regarding the proper U.S. federal income tax treatment of the Securities, and we do not plan to request a ruling from the Internal Revenue Service (the “IRS”). Consequently, significant aspects of the tax treatment of the Securities are uncertain, and the IRS or a court might not agree with the treatment of the Securities as prepaid forward contracts. If the IRS were successful in asserting an alternative treatment for the Securities, the tax consequences of the ownership and disposition of the Securities could be materially and adversely affected.

Even if the treatment of the Securities is respected, the IRS may assert that the Securities constitute “constructive ownership transactions” within the meaning of Section 1260 of the Internal Revenue Code of 1986, as amended (the “Code”), in which case gain recognized in respect of the Securities that would otherwise be long-term capital gain and that was in excess of the “net underlying long-term capital gain” (as defined in Section 1260) would be treated as ordinary income, and a notional interest charge would apply as if that income had accrued for tax purposes at a constant yield over the Securities’ term. Our special tax counsel has not expressed an opinion with respect to whether the constructive ownership rules apply to the Securities.

In addition, as described below under “What Are the Tax Consequences of an Investment in the Securities?,” in 2007 the U.S. Treasury Department and the IRS released a notice requesting comments on various issues regarding the U.S. federal income tax treatment of

FWP-10

“prepaid forward contracts” and similar instruments. Any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the Securities, possibly with retroactive effect. You should review carefully the sections of the accompanying prospectus supplement entitled “Certain U.S. Federal Income Tax Considerations—Certain Notes Treated as Forward Contracts or Derivative Contracts” and, if you are a non-U.S. holder, “—Tax Treatment of Non-U.S. Holders,” and consult your tax advisor regarding the U.S. federal tax consequences of an investment in the Securities (including the potential application of the constructive ownership rules, possible alternative treatments and the issues presented by the 2007 notice), as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Hypothetical Examples and Return Table of the Securities at Maturity

The examples and table below illustrate the payment at maturity for a $10 principal amount Security on a hypothetical offering of Securities under various scenarios, with the assumptions set forth below. The hypothetical Initial Price of $100.00 has been chosen for illustrative purposes only and may not represent a likely actual Initial Price. The actual Initial Price and resulting Trigger Price will be based on the closing price of the Underlying Equity on the Trade Date, and the actual Final Price will be the closing price of the Underlying Equity on the Final Valuation Date. For historical data regarding the actual closing price of the Underlying Equity, please see the historical information set forth under the section titled “Vanguard FTSE Emerging Markets ETF” below. The actual Participation Rate will be set on the Trade Date. Numbers appearing in the examples and table below have been rounded for ease of analysis. These examples and table below do not take into account any tax consequences from investing in the Securities. We cannot predict the closing price of the Underlying Equity on any day during the term of the Securities, including on the Final Valuation Date. You should not take these examples or the table below as an indication or assurance of the expected performance of the Securities.

Term:	5 years
Hypothetical Initial Price:	$100.00
Hypothetical Trigger Price:	$75.00 (75% of the hypothetical Initial Price)
Hypothetical Participation Rate:	131.00% (the midpoint of the range of 126.00% to 136.00%)

Final Price	Equity Return1	Payment at Maturity	Total Return on Securities at Maturity2
$180.00	80.00%	$20.480	104.80%
$170.00	70.00%	$19.170	91.70%
$160.00	60.00%	$17.860	78.60%

1	The Equity Return excludes any cash dividend payments.
2	The “total return” is the number, expressed as a percentage, that results from comparing the payment at maturity per $10 principal amount Security to the purchase price of $10 per Security.

Example 1 — The closing price of the Underlying Equity increases 10.00% from the Initial Price of $100.00 to a Final Price of $110.00, resulting in an Equity Return of 10.00%. Because the Equity Return of 10.00% is positive, the Issuer will pay a payment at maturity calculated as follows per $10 principal amount Security:

$10 + ($10 × Equity Return × Participation Rate)
$10 + ($10 × 10.00% × 131.00%) = $10 + $1.31 = $11.310

The payment at maturity of $11.310 per $10 principal amount Security represents a total return on the Securities of 13.10%.

FWP-12

Example 2 — The closing price of the Underlying Equity decreases 10.00% from the Initial Price of $100.00 to a Final Price of $90.00, resulting in an Equity Return of -10.00%.

Because the Equity Return is negative and the Final Price is greater than or equal to the Trigger Price, the Issuer will repay the full principal amount at maturity of $10.000 per $10 principal amount Security.

The payment at maturity of $10.000 per $10 principal amount Security represents a total return on the Securities of 0.00%.

Example 3 — The closing price of the Underlying Equity decreases 60.00% from the Initial Price of $100.00 to a Final Price of $40.00, resulting in an Equity Return of -60.00%.

Because the Equity Return is negative and the Final Price is less than the Trigger Price, the Issuer will pay a payment at maturity calculated as follows per $10 principal amount Security:

$10 + ($10 × Equity Return)

$10 + ($10 × -60.00%) = $10 + -$6 = $4.000

The payment at maturity of $4.000 per $10 principal amount Security represents a loss on the Securities of 60.00%, which reflects the Equity Return of -60.00%.

If the Equity Return is negative and the Final Price is less than the Trigger Price, at maturity the Issuer will repay less than the full principal amount, if anything, resulting in a loss of principal to investors that is proportionate to the decline of the Underlying Equity from the Trade Date to the Final Valuation Date.

FWP-13

What Are the Tax Consequences of an Investment in the Securities?

You should review carefully the sections entitled “Certain U.S. Federal Income Tax Considerations—Certain Notes Treated as Forward Contracts or Derivative Contracts” and, if you are a non-U.S. holder, “—Tax Treatment of Non-U.S. Holders,” in the accompanying prospectus supplement. The following discussion, when read in combination with those sections, constitutes the full opinion of our special tax counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the Securities. The following discussion supersedes the discussion in the accompanying prospectus supplement to the extent it is inconsistent therewith.

Based on current market conditions, in the opinion of our special tax counsel, it is reasonable to treat the Securities for U.S. federal income tax purposes as prepaid forward contracts with respect to the Underlying Equity. Assuming this treatment is respected, subject to the possible application of the constructive ownership rules, the gain or loss on your Securities should be treated as long-term capital gain or loss if you hold your Securities for more than a year, whether or not you are an initial purchaser of Securities at the original issue price. The Securities could be treated as constructive ownership transactions within the meaning of Section 1260 of the Code, in which case any gain recognized in respect of the Securities that would otherwise be long-term capital gain and that was in excess of the “net underlying long-term capital gain” (as defined in Section 1260) would be treated as ordinary income, and a notional interest charge would apply as if that income had accrued for tax purposes at a constant yield over the Securities’ term. Our special tax counsel has not expressed an opinion with respect to whether the constructive ownership rules apply to the Securities. Accordingly, U.S. holders should consult their tax advisors regarding the potential application of the constructive ownership rules.

The IRS or a court may not respect the treatment of the Securities described above, in which case the timing and character of any income or loss on the Securities could be materially and adversely affected. In addition, in 2007 the U.S. Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; the relevance of factors such as the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the constructive ownership regime described above. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the Securities, possibly with retroactive effect. You should consult your tax advisor regarding the U.S. federal income tax consequences of an investment in the Securities, including the potential application of the constructive ownership rules, possible alternative treatments and the issues presented by this notice.

Non-U.S. holders should note that recently promulgated Treasury regulations imposing a withholding tax on certain “dividend equivalents” under certain “equity linked instruments” will not apply to the Securities.

Investment Objective and Strategy

The Fund seeks to track the performance of a benchmark index that measures the investment return of stocks issued by companies located in emerging market countries. The Fund employs an indexing investment approach by investing substantially all (normally about 95%) of its assets in the common stocks included in the benchmark index (while employing a form of sampling). The Fund currently tracks the performance of the FTSE Emerging Index (the “Underlying Index”). The Underlying Index was developed by FTSE International Limited (“FTSE”) and is calculated, maintained and published by FTSE. FTSE is under no obligation to continue to publish, and may discontinue or suspend the publication of the Underlying Index at any time.

Historically, the Fund sought to track the performance of the MSCI Emerging Markets Index (see relevant disclosure under “Non-Proprietary Indices—Equity Indices—MSCI Indices” in the accompanying index supplement). Starting in January of 2013, the Fund began a two-step transition process to instead track the performance of the Underlying Index. First, in January 2013, the Fund began tracking the performance of the FTSE Emerging Transition Index, which operated until June 28, 2013. Second, on June 28, 2013, the Fund began to track the Underlying Index. The FTSE Emerging Transition Index was created to provide Vanguard with the ability to transition existing emerging markets funds to the Underlying Index over a period of approximately six months in a manner designed to reduce the impact on its existing fund shareholders. The FTSE Emerging Transition Index differed from the Underlying Index in the following ways:

¨ It contained Korean companies: FTSE classified South Korea as a developed market in September 2009, and since then, it has not been a member of FTSE’s emerging indices. FTSE initially included the constituents of the FTSE Korea Index in the transition index universe, and then over a 25-week period, gradually reduced the weight of South Korea in the index.

¨ It contained P Chips: FTSE announced that it would move P Chips (as defined below) from Hong Kong (a developed market) to China (an emerging market) across all its indexes beginning March 18, 2013. In anticipation of this change, P Chips were included in the FTSE Emerging Transition Index from its launch. Subsequently, at the March 2013 review, FTSE removed P Chips from the FTSE Emerging Transition Index. A P Chip is a company controlled by mainland individuals, with the establishment and origin of the company in mainland China. A P Chip must be incorporated outside of the People’s Republic of China and traded on the Stock Exchange of Hong Kong, with a majority of its revenue or assets derived from mainland China.

¨ It contained March 2013 indicative additions and deletions: FTSE has announced a list of indicative additions and deletions that would be applied at the March 2013 index reviews. These companies were incorporated into the FTSE Emerging Transition Index at the start of its calculation.

¨ It was based on actual free float: FTSE announced that beginning March 18, 2013, the Underlying Index would adopt actual free float percentages. In anticipation of this change, the FTSE Emerging Transition Index applied actual free float from its launch.

Additionally, in June 2015, Vanguard announced that the Fund will transition to tracking the FTSE Emerging Markets All Cap China A Inclusion Index (the “Target Index”) in the third or fourth quarter of 2015. The transition will take place in two phases. In the first phase, the Fund will track the FTSE Emerging Markets All Cap China A Inclusion Transition Index (the “Transition Index”), an interim index that will gradually increase exposure to small-capitalization stocks and China A-shares while proportionately reducing exposure to other stocks based on their weightings in the new index. China A-shares, which are securities of Chinese incorporated companies that are quoted in Renminbi, can only be traded by either residents of the People’s Republic of China or under the qualified foreign institutional investor (“QFII”) rules and stock connect schemes. In the second phase, the Fund will begin to track the Target Index, which will be quota-adjusted by FTSE to take into account the quota amount allocated to foreign investors by the Chinese regulator. The gradual changes in the Interim Index over the course of a year are expected to result in the Interim Index eventually replicating the Target Index.

The principal differences between the Underlying Index and the Target Index are that the former represents the performance of large- and mid-capitalization companies in emerging markets, excluding China A-shares, whereas the latter also represents the performance of small-capitalization companies in emerging markets and includes China A-shares. As a result of this transition, the Underlying Equity will be exposed to risks associated with investing both in mainland China and in small-capitalization stocks. For additional information about the

FWP-15

Interim Index and the Target Index, see the information set forth under “— The FTSE Emerging Markets All Cap China A Inclusion Transition Index” and “— The FTSE Emerging Markets All Cap China A Inclusion Index” below.

During both the transition and final benchmark phases, the Fund will invest by sampling the relevant index, meaning that it will hold a broadly diversified collection of securities that, in the aggregate, approximates the full index in terms of key characteristics. To protect the Fund from the potential for harmful “front running” by traders, the exact timing of the index change and portfolio transition has not been disclosed to investors, but Vanguard expects the index change and portfolio transition to be complete by the end of 2016.

As of September 30, 2015, the Fund’s holdings consisted of companies from the following 20 countries: Brazil, Chile, China, Colombia, Czech Republic, Egypt, Hungary, India, Indonesia, Malaysia, Mexico, Peru, Philippines, Poland, Russia, South Africa, Taiwan, Thailand, Turkey and the United Arab Emirates. In addition, as of that date, the Fund’s four largest holdings by country were China (27.2%), Taiwan (14.4%), India (13.3%) and South Africa (9.4%). As of September 30, 2015, the Fund held 1,061 stocks; the Fund’s ten largest equity securities holdings (constituting 18.00% of the total net assets) were Taiwan Semiconductor Manufacturing Co. Ltd., Tencent Holdings Ltd., China Mobile Ltd., China Construction Bank Corp., Naspers Ltd., Industrial & Commercial Bank of China Ltd., Hon Hai Precision Industry Co. Ltd., Infosys Ltd., Bank of China Ltd. and Housing Development Finance Corp. Ltd.

The Underlying Index

The Underlying Index is a market-capitalization, weighted index representing the performance of 945 large and mid-cap companies in 21 emerging markets (as of September 30, 2015) and is derived from the FTSE Global Equity Index Series. FTSE announced that in March 2013, the Underlying Index would expand by approximately 100 constituents, following the addition of P Chips to the FTSE China Index. The Underlying Index was launched on June 30, 2000, with a base date of December 31, 1986, and a base value of 100.

Eligible Countries – Criteria for Inclusion

The following criteria must be met before a country’s companies can be included in the Underlying Index:

¨ permission for direct equity investment by non-nationals;

¨ availability of accurate and timely data;

¨ non-existence of any significant exchange controls which would prevent the timely repatriation of capital or dividends;

¨ the demonstration of significant international investor interest in the local equity market; and

¨ existence of adequate liquidity in the market.

A country’s classification as developed, advanced emerging, or secondary emerging is largely dependent on the following factors:

¨ wealth (GNI per capita);

¨ total stock market capitalization;

¨ breadth and depth of market;

¨ any restrictions on foreign investment;

¨ free flow of foreign exchange;

¨ reliable and transparent price discovery;

¨ efficient market infrastructure (trading, reporting and settlement systems, derivatives market, and other factors); and

¨ oversight by independent regulator

Determining Company Nationality

A company will be allocated to a single country. If a company is incorporated in one country and has its sole listing in the same country, the company will be allocated to that country. In other circumstances, FTSE will refer the company to the FTSE Nationality Committee, which will decide the appropriate nationality for the company. If a company is incorporated in a country, has a listing in that country and listings in other countries, the FTSE Nationality Committee will normally assign the company to the country of incorporation. If a company is incorporated in a country, and is listed only in countries other than the country of incorporation, the FTSE Nationality Committee will normally allocate the company to the country with the greatest liquidity. If a company is incorporated in a country other than a developed country, has no listing in that country and is listed only in one or more developed countries, that company will only be eligible for FTSE Global Equity Index Series inclusion if the country of incorporation is internationally recognized as having a low taxation status that has been approved by the FTSE Nationality Committee.

Eligible Securities

Most types of equity securities are eligible for the Underlying Index. Companies in the business of holding equity and other investments (e.g., investment trusts) which are assumed by the Industry Classification Benchmark as Subsector equity investment instruments and non-equity investment instruments which are assumed by the Industry Classification Benchmark as Subsector non-equity investment instruments are not eligible for inclusion. Limited liability partnerships and limited liability companies are not eligible for inclusion. Where a unit comprises equity and non-equity, it will not be eligible for inclusion. Convertible preferred shares and loan stocks are excluded until converted.

Adjustments Applied to Eligible Securities

Eligible companies may be subject to adjustment for free float and multiple classes, as described below.

FWP-16

Free float restrictions include:

¨ shares directly owned by state, regional, municipal and local governments (excluding shares held by independently managed pension plans for governments);

¨ shares held by sovereign wealth funds where each holding is 10% or greater. If the holding subsequently decreases below 10%, the shares will remain restricted until the holding falls below 7%;

¨ shares held by directors, senior executives and managers of the company, and by their family and direct relations, and by companies with which they are affiliated;

¨ shares held within employee share plans;

¨ shares held by public companies or by non-listed subsidiaries of public companies;

¨ shares held by founders, promoters, former directors, founding venture capital and private equity firms, private companies and individuals (including employees) where the holding is 10% or greater. If the holding subsequently decreases below 10%, the shares will remain restricted until the holding falls below 7%;

¨ all shares where the holder is subject to a lock-up provision (for the duration of that provision);

¨ shares held for publicly announced strategic reasons, including shares held by several holders acting in concert; and

¨ shares that are subject to on-going contractual agreements (such as swaps) where they would ordinarily be treated as restricted.

Where there are multiple classes of equity capital in a company, all classes are included and priced separately, provided that:

¨ The secondary class’s full market capitalization (i.e., before the application of any investability weightings) is greater than 25% of the full market capitalization of the company’s principal class and the secondary class is eligible in its own right in all respects.

¨ All partly-paid classes of equity are priced on a fully-paid basis if the calls are fixed and are payable at known future dates. Those where future calls are uncertain in either respect are priced on a partly-paid basis.

Liquidity of Constituents

Each constituent security will be tested for liquidity by calculation of its median daily trading per month. The median trade is calculated by ranking each daily trade total and selecting the middle ranking day. Daily totals with zero trades are included in the ranking; therefore, a security that fails to trade for more than half of the days in a month will have a median trade of zero.

A non-constituent which does not turnover at least 0.05% of its outstanding shares (after the application of any free float weightings) based on its median daily trade per month for at least ten of the twelve months prior to a full market review will not be eligible for inclusion in the Index Series. An existing constituent which does not turnover at least 0.04% of its shares in issue (after the application of any free float weightings) based on its median daily trade per month for at least eight of the twelve months prior to a full market review will be removed. New issues which do not have a twelve month trading record must have a minimum three month trading record when reviewed. They must turnover at least 0.05% of their outstanding shares (after the application of any free float weightings) based on their median daily trade per month in each month since their listing.

If a company fails the liquidity test based on its underlying shares, its Depositary Receipts (“DR”) may be considered for inclusion in the index if it passes the liquidity test in its own right and is traded on an exchange within the same regional time zone in which the underlying shares are listed. Where a company has both a DR and underlying shares listed, both securities will be tested separately for liquidity. The underlying share will be included if it passes the liquidity test in its own right. The DR will only be eligible for inclusion if the underlying share fails the liquidity test and the DR passes in its own right. Where the DR has been included, it will remain in the index until it either fails the liquidity test or the underlying share passes a future liquidity test with greater liquidity than the DR. In the event that the underlying share fails the liquidity test and the DR trades in a different time zone, but passes the test in its own right, the underlying share will be included as long as the DR is fully fungible (i.e., the DR can be converted into underlying shares and the underlying shares can be converted into DRs).

Calculation of the Underlying Index

Actual closing mid-market or last trade prices are used, where available, for constituent securities with local securities exchange quotations. The number of shares outstanding for each constituent security is expressed to the nearest share. To prevent a large number of insignificant weighting changes, the number of shares outstanding for each constituent security is amended only when the total outstanding shares included in the index system changes by more than 1% on a cumulative basis. Changes will be made quarterly after the close of business on the third Friday of March, June, September and December. The performance of the FTSE Global Equity Index Series on a given day is determined by calculating the percentage difference between (1) the index’s market capitalization as at the close of that day, and (2) the market capitalization at the start of that day. “Start of the day” is defined as the previous day’s close adjusted for capital changes, investability weight changes, additions and deletions.

The FTSE Emerging Markets All Cap China A Inclusion Transition Index

The Interim Index will be calculated over twelve months and at the start of the transition will only contain constituents of the FTSE Emerging Index. On a monthly basis, a proportion of small-capitalization and China A-share companies will be added until at the end of the year-long transition, the composition is aligned with the Target Index. The weight of China A-shares and small-capitalization companies will be adjusted after the third Friday of each month using a factor approach. At the start of the index calculation, China A-shares and small-capitalization companies will have a factor of 0 applied to their free-float adjusted market capitalizations. Each month, the factor will be increased by 8.33%. At month 12, the full weight of China A-shares and small cap companies will have been added to the Interim Index and the index constituents and weightings will be aligned with the Target Index.

FWP-17

The constituents’ weights in the Interim Index are neutralized between transition reviews when a corporate event leads to a rise or fall in index weighting for a constituent could potentially be reversed at the next monthly transition review. This may cause FTSE to adjust the factor applied to an index constituent’s market capitalization.

The FTSE Emerging Markets All Cap China A Inclusion Index

The Target Index is a market-capitalization weighted index representing the performance of large, mid and small-cap companies in emerging markets. The Target Index was launched on June 5, 2015, with a base date of December 31, 2005 and a base value of 1,000.

The Target Index will apply the same methodology as the FTSE Emerging Index, except the Target Index will include small capitalization stocks and China A-shares at a weighting equivalent to the aggregate QFII and/or Renminbi QFII (“RQFII”) approved quota for international investors. The China A-shares weighting will increase as total QFII and RQFII allocations increase. A built-in mechanism ensures that the allocation of China A-shares is adjusted proportional to the changes in the approved quota and is in line with the accessibility available to international investors.

Historical Information

The following table sets forth the quarterly high, low and period-end closing prices for the Underlying Equity, based on daily closing prices of the Underlying Equity. The closing price of the Underlying Equity on October 23, 2015 was $36.41. The actual Initial Price will be the closing price of the Underlying Equity on the Trade Date.

We obtained the closing prices below from Bloomberg, without independent verification. Historical performance of the Underlying Equity should not be taken as an indication of future performance. Future performance of the Underlying Equity may differ significantly from historical performance, and no assurance can be given as to the closing price of the Underlying Equity during the term of the Securities, including on the Final Valuation Date. Furthermore, due to the recent transitions in the Underlying Equity’s underlying index, as described above, the Underlying Equity’s historical performance may be of limited value in assessing its performance. We cannot give you assurance that the performance of the Underlying Equity will result in the return of any of your initial investment. The closing prices below may have been adjusted to reflect certain corporate actions such as stock splits and reverse stock splits.
