Barclays Clarifies Treatment of Corporate Actions Affecting Constituents of the Atlantic Trust Select MLP Index

May 1, 2017

Atlantic Trust Select MLP Index used as underlying index in the Barclays ETN+ Select MLP ETNs (ticker: ATMP)

On April 28, 2017, Energy Transfer Partners (NYSE:ETP) and Sunoco Logistics Partners (NYSE:SXL), two constituents of the Atlantic Trust Select MLP Index (the “Index”), closed on their previously announced merger, in which SXL acquired ETP. Effective with the opening of market on April 28, 2017, ETP ceased to be a publicly traded company, and its common units previously listed on the NYSE under the ticker symbol “ETP” were de-listed. The de-listing was originally scheduled to be effective on May 1, 2017; however, the change in the de-listing date of ETP was made after the close of the Index on April 27, 2017.

Due to the late change in the effective date of the de-listing, Barclays Bank PLC, as index sponsor of the Index (the “Index Sponsor”), has determined that the Index will continue to retain the previous de-listing schedule for the ETP holding. Therefore, the Index Sponsor will treat the ETP de-listing as effective on May 1, 2017 for purposes of the Index. The effective price of ETP used in the Index level for April 28, 2017 will use the full day Volume-Weighted Average Price (“VWAP”) price of SXL on April 28, 2017 multiplied by a factor of 1.5. The effective price of ETP used in the Index level for April 28, 2017 will be $35.89, based on a full day VWAP price on SXL equal to $23.925.

A notional cash allocation equal to the number of constituent shares of ETP, multiplied by the effective price of ETP on April 28, 2017, will replace the allocation to ETP in the Index from and including May 1, 2017. Such cash allocation will remain in the Index until the next scheduled rebalance and will be reinvested into the Index on the next rebalancing date. The next Index rebalance will commence on July 14, 2017. The Index is rebalanced quarterly over four index business days.

The Index is designed to provide exposure to a basket of midstream U.S. and Canadian master limited partnerships, limited liability companies and corporations (collectively, the “Index Constituents”) that trade on major U.S. exchanges, are classified in the GICS^® Energy Sector or GICS^® Gas Utilities Industry according to the Global Industry Classification Standard^® (“GICS”) and meet certain eligibility criteria. The Index Constituents are selected for inclusion in the Index using the Atlantic Trust Select Master Limited Partnership Strategy (the “Strategy”) developed by AT Investment Advisers, Inc. (the “Index Selection Agent”). The Strategy dynamically selects a basket of up to 100 Index Constituents based on their long-term credit rating, the portion of their cash flow driven by mid-stream operations and their size as measured by free-float market capitalization and average daily trading value. The Index Selection Agent provides the Index Constituents selected by the Strategy to Barclays Bank PLC as Index Sponsor. Constituent additions to and deletions from the Index do not reflect an opinion by Barclays Bank PLC on the investment merits of the respective securities.

The Barclays ETN+ Select MLP ETNs (the “ETNs”) are linked to the performance of the VWAP of the Index. The ETNs were listed on the NYSE Arca stock exchange in March 2013 under the ticker symbol ATMP. An investment in the ETNs involves significant risks, including possible loss of principal, and may not be suitable for all investors. The ETNs are riskier than ordinary unsecured debt securities and have no principal protection. The ETNs are speculative and may exhibit high volatility. The ETNs are also subject to certain investor fees, which will have a negative effect on the value of the ETNs. You are not guaranteed to receive coupon payments on the ETNs. You will receive a coupon payment on a coupon payment date only to the extent that the accrued dividend exceeds the accrued investor fee on the relevant coupon valuation date.

Owning the ETNs is not the same as owning interests in the Index Constituents or a security directly linked to the performance of the Index.

Selected Risk Considerations

An investment in any ETNs linked to the Atlantic Trust Select MLP Index (the “ETNs”) involves risks. Selected risks are summarized here, but we urge you to read the more detailed explanation of risks described under “Risk Factors” in the applicable prospectus supplement and pricing supplement.

You May Lose Some or All of Your Principal: The ETNs are exposed to any decrease in the Volume Weighted Average Price (“VWAP”) level between the inception date and the applicable valuation date. Additionally, if the VWAP level is insufficient to offset the negative effect of the investor fee and other applicable costs, you will lose some or all of your investment at maturity or upon redemption, even if the VWAP value has increased. Because the ETNs are subject to an investor fee and any other applicable costs, the return on the ETNs will always be lower than the total return on a direct investment in the index components. The ETNs are riskier than ordinary unsecured debt securities and have no principal protection.

Credit of Barclays Bank PLC: The ETNs are unsecured debt obligations of the issuer, Barclays Bank PLC, and are not, either directly or indirectly, an obligation of or guaranteed by any third party. Any payment to be made on the ETNs, including any payment at maturity or upon redemption, depends on the ability of Barclays Bank PLC to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of Barclays Bank PLC will affect the market value, if any, of the ETNs prior to maturity or redemption. In addition, in the event Barclays Bank PLC were to default on its obligations, you may not receive any amounts owed to you under the terms of the ETNs.

Issuer Redemption: Barclays Bank PLC will have the right to redeem or “call” the ETNs (in whole but not in part) at its sole discretion and without your consent on any trading day on or after the inception date until and including maturity.

The Payment on the ETNs is Linked to the VWAP Level, Not to the Closing Level of the Index and Not to the Published Intraday Indicative Value of the ETNs: Your payment at maturity or upon early redemption is linked to the performance of the VWAP level, as compared to the initial VWAP level. Although the VWAP level is intended to track the performance of the Index, the calculation of the VWAP level is different from the calculation of the official closing level of the Index. Therefore, the payment at maturity or early redemption of your ETNs, may be different from the payment you would receive if such payment were determined by reference to the official closing level of the Index.

No Guaranteed Coupon Payments: You are not guaranteed to receive coupon payments on the ETNs. You will receive a coupon payment on a coupon payment date only to the extent that the accrued dividend exceeds the accrued investor fee on the relevant coupon valuation date. The amount of the accrued dividend on any coupon valuation date depends in part on the aggregate cash value of distributions that a reference holder would have been entitled to receive in respect of the index constituents prior to the relevant coupon valuation date.

Market and Volatility Risk: The return on the ETNs is linked to the performance of the VWAP level of the Index which, in turn, is linked to the performance of the master limited partnerships and other securities that are included as index constituents at any time. The prices of the index constituents may change unpredictably and, as a result, affect the level of the Index and the value of your ETNs in unforeseeable ways.

Concentration Risk: The index constituents are companies in the Energy Sector or Gas Utilities Sector, as determined by the GICS^® classification system. In addition, many of the index constituents are smaller, non-diversified businesses that are exposed to the risks associated with such businesses, including the lack of capital funding to sustain or grow businesses and potential competition from larger, better financed and more diversified businesses. The ETNs are susceptible to general market fluctuations in the energy and gas MLP market and to volatile increases and decreases in value, as market confidence in, and perceptions regarding the index constituents change. Your investment may therefore carry risks similar to a concentrated securities investment in one industry or sector.

A Trading Market for the ETNs May Not Develop: Although the ETNs are listed on NYSE Arca, a trading market for the ETNs may not develop and the liquidity of the ETNs may be limited, as we are not required to maintain any listing of the ETNs.

Restrictions on the Minimum Number of ETNs and Date Restrictions for Redemptions: You must redeem at least 50,000 ETNs at one time in order to exercise your right to redeem your ETNs on any redemption date. You may only redeem your ETNs on a redemption date if we receive a notice of redemption from you by certain dates and times as set forth in the pricing supplement.

Tax Treatment: Significant aspects of the tax treatment of the ETNs may be less favorable than a direct investment in MLPs and are uncertain. You should consult your own tax advisor about your own tax situation.
