Self-Regulatory Organizations; NYSE Arca, Inc.; Notice of Filing of Amendment No. 5 and Order Granting Accelerated Approval of a Proposed Rule Change, as Modified by Amendment No. 5, To List and Trade Two Series of Active Proxy Portfolio Shares Issued by the American Century ETF Trust Under NYSE Arca Rule 8.601-E

I. Introduction

On December 23, 2019, NYSE Arca, Inc. (“NYSE Arca” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) and Rule 19b-4 thereunder, a proposed rule change to list and trade shares (“Shares”) of the following under NYSE Arca Rule 8.601-E (Active Proxy Portfolio Shares): American Century Mid Cap Growth Impact ETF and American Century Sustainable Equity ETF (“Funds”). The proposed rule change was published for comment in the Federal Register on January 3, 2020.

On February 13, 2020, pursuant to Section 19(b)(2) of the Act, the Commission designated a longer period within which to approve the proposed rule change, disapprove the proposed rule change, or institute proceedings to determine whether to disapprove the proposed rule change. On March 31, 2020, the Exchange filed Amendment No. 2 to the proposed rule change, which replaced and superseded the proposed rule change as originally filed. On April 1, 2020, the Commission published Amendment No. 2 for notice and comment and instituted proceedings under Section 19(b)(2)(B) of the Act to determine whether to approve or disapprove the proposed rule change. On May 20, 2020, the Exchange filed Amendment No. 3 to the proposed rule change, which replaced and superseded the proposed rule change, as amended by Amendment No. 2. On June 15, 2020, the Exchange filed Amendment No. 4 to the proposed rule change, which replaced and superseded the proposed rule change, as amended by Amendment No. 3. On June 19, 2020, the Exchange filed Amendment No. 5 to the proposed rule change, which replaced and superseded the proposed rule change, as amended by Amendment No. 4. The Commission has received no comments on the proposed rule change. The Commission is publishing this notice to solicit comments on the proposed rule change, as modified by Amendment No. 5, from interested persons and is approving the proposed rule change, as modified by Amendment No. 5, on an accelerated basis.

II. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change, as Modified by Amendment No. 5

In its filing with the Commission, the self-regulatory organization included statements concerning the purpose of, and basis for, the proposed rule change and discussed any comments it received on the proposed rule change. The text of those statements may be examined at the places specified in Item IV below. The Exchange has prepared summaries, set forth in sections A, B, and C below, of the most significant parts of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

1. Purpose

The Exchange has proposed to add new NYSE Arca Rule 8.601-E for the purpose of permitting the listing and trading, or trading pursuant to unlisted trading privileges (“UTP”), of Active Proxy Portfolio Shares, which are securities issued by an actively managed open-end investment management company. Proposed Commentary .01 to Rule 8.601-E would require the Exchange to file separate proposals under Section 19(b) of the Act before listing and trading any series of Active Proxy Portfolio Shares on the Exchange. Therefore, the Exchange is submitting this proposal in order to list and trade shares (“Shares”) of Active Proxy Portfolio Shares of the American Century Mid Cap Growth Impact ETF and American Century Sustainable Equity ETF (each a “Fund” and, collectively, the “Funds”) under proposed Rule 8.601-E.

Key Features of Active Proxy Portfolio Shares

While funds issuing Active Proxy Portfolio Shares will be actively-managed and, to that extent, will be similar to Managed Fund Shares, Active Proxy Portfolio Shares differ from Managed Fund Shares in the following important respects. First, in contrast to Managed Fund Shares, which are actively-managed funds listed and traded under NYSE Arca Rule 8.600-E and for which a “Disclosed Portfolio” is required to be disseminated at least once daily, the portfolio for an issue of Active Proxy Portfolio Shares will be publicly disclosed within at least 60 days following the end of every fiscal quarter in accordance with normal disclosure requirements otherwise applicable to open-end management investment companies registered under the 1940 Act. The composition of the portfolio of an issue of Active Proxy Portfolio Shares would not be available at commencement of Exchange listing and trading. Second, in connection with the creation and redemption of Active Proxy Portfolio Shares, such creation or redemption may be exchanged for a Proxy Portfolio with a value equal to the next-determined NAV.

A series of Active Proxy Portfolio Shares will disclose the Proxy Portfolio on a daily basis, which, as described above, is designed to track closely the daily performance of the Actual Portfolio of a series of Active Proxy Portfolio Shares, instead of the actual holdings of the Investment Company, as provided by a series of Managed Fund Shares.

In this regard, with respect to the Funds, the Funds will utilize a proxy portfolio methodology—the “NYSE Proxy Portfolio Methodology”—that would allow market participants to assess the intraday value and associated risk of a Fund's Actual Portfolio and thereby facilitate the purchase and sale of Shares by investors in the secondary market at prices that do not vary materially from their NAV. The NYSE Proxy Portfolio Methodology would utilize creation of a Proxy Portfolio for hedging and arbitrage purposes.

The Exchange, after consulting with various Lead Market Makers (“LMMs”) that trade exchange-traded funds (“ETFs”) on the Exchange, believes that market makers will be able to make efficient and liquid markets priced near the ETF's intraday value, and market makers employ market making techniques such as “statistical arbitrage,” including correlation hedging, beta hedging, and dispersion trading, which is currently used throughout the financial services industry, to make efficient markets in exchange-traded products. For Active Proxy Portfolio Shares, market makers may use the knowledge of a fund's means of achieving its investment objective, as described in the applicable fund registration statement, as well as a fund's disclosed Proxy Portfolio, to construct a hedging proxy for a fund to manage a market maker's quoting risk in connection with trading fund shares. Market makers can then conduct statistical arbitrage between their hedging proxy and shares of a fund, buying and selling one against the other over the course of the trading day. This ability should permit market makers to make efficient markets in an issue of Active Proxy Portfolio Shares without precise knowledge of a fund's underlying portfolio. This is similar to certain other existing exchange-traded products (for example, ETFs that invest in foreign securities that do not trade during U.S. trading hours), in which spreads may be generally wider in the early days of trading and then narrow as market makers gain more confidence in their real-time hedges.

Description of the Funds and the Trust

The Funds will be series of the American Century ETF Trust (“Trust”), which will be registered with the Commission as an open-end management investment company.

American Century Investment Management, Inc. (“Adviser”) will be the investment adviser to the Funds. Foreside Fund Services, LLC will act as the distributor and principal underwriter (“Distributor”) for the Funds. State Street Bank and Trust Company will serve as transfer agent (“Transfer Agent”) for the Funds.

Proposed Commentary.04 provides that, if the investment adviser to the Investment Company issuing Active Proxy Portfolio Shares is registered as a broker-dealer or is affiliated with a broker-dealer, such investment adviser will erect and maintain a “fire wall” between the investment adviser and personnel of the broker-dealer or broker-dealer affiliate, as applicable, with respect to access to information concerning the composition and/or changes to such Investment Company's Actual Portfolio and/or Proxy Portfolio. Any person related to the investment adviser or Investment Company who makes decisions pertaining to the Investment Company's Actual Portfolio and/or Proxy Portfolio or has access to non-public information regarding the Investment Company's Actual Portfolio and/or Proxy Portfolio or changes thereto must be subject to procedures reasonably designed to prevent the use and dissemination of material non-public information regarding the Actual Portfolio and/or Proxy Portfolio or changes thereto. Proposed Commentary .04 is similar to Commentary .03(a)(i) and (iii) to NYSE Arca Rule 5.2-E(j)(3); however, proposed Commentary .04, in connection with the establishment of a “fire wall” between the investment adviser and the broker-dealer, reflects the applicable open-end fund's portfolio, not an underlying benchmark index, as is the case with index-based funds. Proposed Commentary .04 is also similar to Commentary .06 to Rule 8.600-E related to Managed Fund Shares, except that proposed Commentary .04 relates to establishment and maintenance of a “fire wall” between the investment adviser and personnel of the broker-dealer or broker-dealer affiliate, as applicable, applicable to an Investment Company's Actual Portfolio and/or Proxy Portfolio or changes thereto, and not just to the underlying portfolio, as is the case with Managed Fund Shares.

In addition, proposed Commentary.05 provides that any person or entity, including a custodian, Reporting Authority, distributor, or administrator, who has access to non-public information regarding the Investment Company's Actual Portfolio or the Proxy Portfolio or changes thereto, must be subject to procedures reasonably designed to prevent the use and dissemination of material non-public information regarding the applicable Investment Company Actual Portfolio or the Proxy Portfolio or changes thereto. Moreover, if any such person or entity is registered as a broker-dealer or affiliated with a broker-dealer, such person or entity will erect and maintain a “fire wall” between the person or entity and the broker-dealer with respect to access to information concerning the composition and/or changes to such Investment Company Actual Portfolio or Proxy Portfolio.

The Adviser is not registered as a broker-dealer but is affiliated with a broker-dealer. The Adviser has implemented and will maintain a “fire wall” with respect to such broker-dealer affiliate regarding access to information concerning the composition of and/or changes to a Fund's Actual Portfolio or Proxy Portfolio.

In the event (a) the Adviser becomes registered as a broker-dealer or becomes newly affiliated with a broker-dealer, or (b) any new adviser or sub-adviser is a registered broker-dealer, or becomes affiliated with a broker-dealer, it will implement and maintain a fire wall with respect to its relevant personnel or its broker-dealer affiliate regarding access to information concerning the composition and/or changes to a Fund's Actual Portfolio and/or Proxy Portfolio, and will be subject to procedures designed to prevent the use and dissemination of material non-public information regarding a Fund's Actual Portfolio and/or Proxy Portfolio or changes thereto. Any person related to the Adviser or a Fund who makes decisions pertaining to the Fund's Actual Portfolio and/or the Proxy Portfolio or has access to non-public information regarding a Fund's Actual Portfolio and/or the Proxy Portfolio or changes thereto are subject to procedures reasonably designed to prevent the use and dissemination of material non-public information regarding a Fund's Actual Portfolio and/or the Proxy Portfolio or changes thereto.

In addition, any person or entity, including any service provider for a Fund, who has access to non-public information regarding a Fund's Actual Portfolio or the Proxy Portfolio or changes thereto, will be subject to procedures reasonably designed to prevent the use and dissemination of material non-public information regarding a Fund's Actual Portfolio and/or the Proxy Portfolio or changes thereto. Moreover, if any such person or entity is registered as a broker-dealer or affiliated with a broker-dealer, such person or entity has erected and will maintain a “fire wall” between the person or entity and the broker-dealer with respect to access to information concerning the composition and/or changes to a Fund's Actual Portfolio and/or Proxy Portfolio.

The Funds

According to the Application, the Adviser believes a Fund would allow for efficient trading of Shares through an effective Fund portfolio transparency substitute and publication of related information metrics, while still shielding the identity of the full Fund portfolio contents to protect a Fund's performance-seeking strategies. Even though a Fund would not publish its full portfolio contents daily, the Adviser believes that the NYSE Proxy Portfolio Methodology would allow market participants to assess the intraday value and associated risk of a Fund's Actual Portfolio. As a result, the Adviser believes that investors would be able to purchase and sell Shares in the secondary market at prices that are close to their NAV.

In this regard, the Funds will utilize a proxy portfolio methodology—the “NYSE Proxy Portfolio Methodology”—that would allow market participants to assess the intraday value and associated risk of a Fund's Actual Portfolio and thereby facilitate the purchase and sale of Shares of a Fund by investors in the secondary market at prices that do not vary materially from their NAV. The NYSE Proxy Portfolio Methodology would utilize creation of a Proxy Portfolio for hedging and arbitrage purposes.

Each Fund's holdings will conform to the permissible investments as set forth in the American Century Application and American Century Exemptive Order and the holdings will be consistent with all requirements in the American Century Application and American Century Exemptive Order. Any foreign common stocks held by a Fund will be traded on an exchange that is a member of the Intermarket Surveillance Group (“ISG”) or with which the Exchange has in place a comprehensive surveillance sharing agreement.

American Century Mid Cap Growth Impact ETF

According to the Registration Statement, the Fund will seek long-term capital growth. The Fund, under normal market conditions, will invest principally in exchange-traded common stocks and will invest at least 80% of its assets in securities of medium capitalization companies.

American Century Sustainable Equity ETF

According to the Registration Statement, the Fund will seek long-term capital growth. The Fund, under normal market conditions, will invest at least 80% of its assets in equity securities. The Fund will invest principally in exchange-traded common stocks.

Creations and Redemptions of Shares

According to the Registration Statement, the Trust will offer, issue and sell Shares of the Funds to investors only in specified minimum size “Creation Units” through the Distributor on a continuous basis at the NAV per Share next determined after an order in proper form is received. The NAV of a Fund is expected to be determined as of 4:00 p.m. E.T. on each “Business Day.” The “Creation Basket” (as defined below) for a Fund will be based on the Proxy Portfolio, which is designed to approximate the value and performance of the Actual Portfolio. All Creation Basket instruments will be valued in the same manner as they are valued for purposes of calculating a Fund's NAV, and such valuation will be made in the same manner regardless of the identity of the purchaser or redeemer. Further, the total consideration paid for the purchase or redemption of a Creation Unit of Shares will be based on the NAV of such Fund, as calculated in accordance with the policies and procedures set forth in its Registration Statement.

The Trust will sell and redeem Creation Units of each Fund only on a Business Day. Creation Units of the Funds may be purchased and/or redeemed entirely for cash, as permissible under the procedures described below.

In order to keep costs low and permit each Fund to be as fully invested as possible, Shares will be purchased and redeemed in Creation Units and generally on an in-kind basis. Accordingly, except where the purchase or redemption will include cash under the circumstances specified below, purchasers will be required to purchase Creation Units by making an in-kind deposit of specified instruments (“Deposit Instruments”), and shareholders redeeming their Shares will receive an in-kind transfer of specified instruments (“Redemption Instruments”). The names and quantities of the instruments that constitute the Deposit Instruments and the Redemption Instruments for a Fund (collectively, the “Creation Basket”) will be the same as a Fund's Proxy Portfolio, except to the extent purchases and redemptions are made entirely or in part on a cash basis.

If there is a difference between the NAV attributable to a Creation Unit and the aggregate market value of the Creation Basket exchanged for the Creation Unit, the party conveying instruments with the lower value will also pay to the other an amount in cash equal to that difference (the “Cash Amount”).

Each Fund will adopt and implement policies and procedures regarding the composition of its Creation Baskets. The policies and procedures will set forth detailed parameters for the construction and acceptance of baskets in compliance with the terms and conditions of the American Century Exemptive Order and that are in the best interests of a Fund and its shareholders, including the process for any revisions to or deviations from those parameters.

A Fund that normally issues and redeems Creation Units in kind may require purchases and redemptions to be made entirely or in part on a cash basis. In such an instance, a Fund will announce, before the open of trading in the Core Trading Session (normally, 9:30 a.m. to 4:00 p.m., E.T.) on a given Business Day, that all purchases, all redemptions, or all purchases and redemptions on that day will be made wholly or partly in cash. A Fund may also determine, upon receiving a purchase or redemption order from an Authorized Participant, to have the purchase or redemption, as applicable, be made entirely or in part in cash. Each Business Day, before the open of trading on the Exchange, a Fund will cause to be published through the National Securities Clearing Corporation (“NSCC”) the names and quantities of the instruments comprising the Creation Basket, as well as the estimated Cash Amount (if any), for that day. The published Creation Basket will apply until a new Creation Basket is announced on the following Business Day, and there will be no intra-day changes to the Creation Basket except to correct errors in the published Creation Basket.

All orders to purchase Creation Units must be placed with the Distributor by or through an Authorized Participant, which is either: (1) A “participating party” (i.e., a broker or other participant), in the Continuous Net Settlement (“CNS”) System of the NSCC, a clearing agency registered with the Commission and affiliated with the Depository Trust Company (“DTC”), or (2) a DTC Participant, which in any case has executed a participant agreement with the Distributor and the Transfer Agent.

Timing and Transmission of Purchase Orders

All orders to purchase (or redeem) Creation Units, whether using the NSCC Process or the DTC Process, must be received by the Distributor no later than the NAV calculation time (“NAV Calculation Time”), generally 4:00 p.m. E.T. on the date the order is placed (“Transmittal Date”) in order for the purchaser (or redeemer) to receive the NAV determined on the Transmittal Date.

Daily Disclosures

With respect to the Funds, the following information will comprise the “Proxy Portfolio Disclosures” and, pursuant to the American Century Application and Exemptive Order, will be publicly available on the Funds' website ( www.americancenturyetfs.com ) before the commencement of trading in Shares on each Business Day:

• The Proxy Portfolio holdings (including the identity and quantity of investments in the Proxy Portfolio) will be publicly available on the Funds' website before the commencement of trading in Shares on each Business Day.
• The historical “Tracking Error” between a Fund's last published NAV per share and the value, on a per Share basis, of a Fund's Proxy Portfolio calculated as of the close of trading on the prior Business Day will be publicly available on the Funds' website before the commencement of trading in Shares each Business Day.
• The “Proxy Overlap” will be publicly available on the Funds' website before the commencement of trading in Shares on each Business Day. The Proxy Overlap is the percentage weight overlap between the Proxy Portfolio's holdings compared to the Actual Portfolio's holdings that formed the basis for a Fund's calculation of NAV at the end of the prior Business Day. The Proxy Overlap will be calculated by taking the lesser weight of each asset held in common between the Actual Portfolio and the Proxy Portfolio and adding the totals.

Availability of Information

The Funds' website ( www.americancenturyetfs.com ), which will be publicly available prior to the public offering of Shares, will include a form of the prospectus for each Fund that may be downloaded. The Funds' website will include on a daily basis, per Share for each Fund, the prior Business Day's NAV and the “Closing Price” or “Bid/Ask Price,” and a calculation of the premium/discount of the Closing Price or Bid/Ask Price against such NAV. The Adviser has represented that the Funds' website will also provide: (1) Any other information regarding premiums/discounts as may be required for other ETFs under Rule 6c-11 under the 1940 Act, as amended, and (2) any information regarding the bid/ask spread for a Fund as may be required for other ETFs under Rule 6c-11 under the 1940 Act, as amended. The website and information will be publicly available at no charge. Each Fund's website also will disclose the information required under proposed Rule 8.601-E(c)(3). The Proxy Portfolio holdings for each Fund (including the identity and quantity of investments in the Proxy Portfolio) will be publicly available on the Funds' website before the commencement of trading in Shares on each Business Day.

Typical mutual fund-style annual, semi-annual and quarterly disclosures contained in the Funds' Commission filings will be provided on the Funds' website on a current basis. Thus, each Fund will publish the portfolio contents of its Actual Portfolio on a periodic basis within at least 60 days following the end of every fiscal quarter.

Investors can also obtain a Fund's prospectus, SAI, Shareholder Reports, Form N-CSR, N-PORT and Form N-CEN filed with the Commission. The prospectus, SAI and Shareholder Reports are available free upon request from the Trust, and those documents and the Form N-CSR, N-PORT, and Form N-CEN may be viewed on-screen or downloaded from the Commission's website. The Exchange also notes that pursuant to its Exemptive Order, the issuer must comply with Regulation Fair Disclosure, which prohibits selective disclosure of any material non-public information.

Information regarding market price and trading volume of the Shares will be continually available on a real-time basis throughout the day on brokers' computer screens and other electronic services. Information regarding the previous day's closing price and trading volume information for the Shares will be published daily in the financial section of newspapers.

Updated price information for U.S. exchange-listed equity securities is available through major market data vendors or securities exchanges trading such securities. Quotation and last sale information for the Shares, ETFs, ETNs, U.S. exchange-traded common stocks, preferred stocks and ADRs will be available via the Consolidated Tape Association (“CTA”) high-speed line or from the exchange on which such securities trade. Price information for futures, foreign stocks and cash equivalents is available through major market data vendors. Intraday pricing information for all constituents of the Proxy Portfolio that are exchange-traded, which includes all eligible instruments except cash and cash equivalents, will be available on the exchanges on which they are traded and through subscription services. Intraday pricing information for cash equivalents will be available through subscription services and/or pricing services.

Investment Restrictions

The Shares of each Fund will conform to the initial and continued listing criteria under proposed Rule 8.601-E. A Fund's holdings will be limited to and consistent with permissible holdings as described in the Application and all requirements in the Application and Exemptive Order.

Each Fund's investments, including derivatives, will be consistent with its investment objective and will not be used to enhance leverage (although certain derivatives and other investments may result in leverage). That is, a Fund's investments will not be used to seek performance that is the multiple or inverse multiple (e.g., 2X or -3X) of a Fund's primary broad-based securities benchmark index (as defined in Form N-1A).

Trading Halts

With respect to trading halts, the Exchange may consider all relevant factors in exercising its discretion to halt or suspend trading in the Shares of a Fund. Trading in Shares of a Fund will be halted if the circuit breaker parameters in NYSE Arca Rule 7.12-E have been reached. Trading also may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Shares inadvisable. Trading in the Shares will be subject to NYSE Arca Rule 8.601-E(d)(2)(D), which sets forth circumstances under which Shares of a Fund will be halted.

Specifically, proposed Rule 8.601-E(d)(2)(D) provides that the Exchange may consider all relevant factors in exercising its discretion to halt trading in a series of Active Proxy Portfolio Shares. Trading may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the series of Active Proxy Portfolio Shares inadvisable. These may include: (a) The extent to which trading is not occurring in the securities and/or the financial instruments composing the Proxy Portfolio and/or Actual Portfolio; or (b) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. If the Exchange becomes aware that the NAV, Proxy Portfolio or Actual Portfolio with respect to a series of Active Proxy Portfolio Shares is not disseminated to all market participants at the same time, the Exchange shall halt trading in such series until such time as the NAV, Proxy Portfolio or Actual Portfolio is available to all market participants at the same time.

Trading Rules

The Exchange deems the Shares to be equity securities, thus rendering trading in the Shares subject to the Exchange's existing rules governing the trading of equity securities. Shares will trade on the NYSE Arca Marketplace in all trading sessions in accordance with NYSE Arca Rule 7.34-E(a). As provided in NYSE Arca Rule 7.6-E, the minimum price variation (“MPV”) for quoting and entry of orders in equity securities traded on the NYSE Arca Marketplace is $0.01, with the exception of securities that are priced less than $1.00 for which the MPV for order entry is $0.0001.

The Shares will conform to the initial and continued listing criteria under proposed NYSE Arca Rule 8.601-E. The Exchange has appropriate rules to facilitate trading in the Shares during all trading sessions.

A minimum of 100,000 Shares for each Fund will be outstanding at the commencement of trading on the Exchange. In addition, pursuant to proposed Rule 8.601-E(d)(1)(B), the Exchange, prior to commencement of trading in the Shares, will obtain a representation from the issuer of the Shares of each Fund that the NAV per Share will be calculated daily and that the NAV, Proxy Portfolio and the Actual Portfolio for each Fund will be made available to all market participants at the same time.

With respect to Active Proxy Portfolio Shares, all of the Exchange member obligations relating to product description and prospectus delivery requirements will continue to apply in accordance with Exchange rules and federal securities laws, and the Exchange and the Financial Industry Regulatory Authority, Inc. (“FINRA”) will continue to monitor Exchange members for compliance with such requirements.

Surveillance

The Exchange represents that trading in the Shares will be subject to the existing trading surveillances, administered by the Exchange, as well as cross-market surveillances administered by FINRA on behalf of the Exchange, which are designed to detect violations of Exchange rules and applicable federal securities laws. The Exchange represents that these procedures are adequate to properly monitor Exchange trading of the Shares in all trading sessions and to deter and detect violations of Exchange rules and federal securities laws applicable to trading on the Exchange.

The surveillances referred to above generally focus on detecting securities trading outside their normal patterns, which could be indicative of manipulative or other violative activity. When such situations are detected, surveillance analysis follows and investigations are opened, where appropriate, to review the behavior of all relevant parties for all relevant trading violations.

The Exchange or FINRA, on behalf of the Exchange, or both, will communicate as needed regarding trading in the Shares and underlying exchange-traded instruments with other markets and other entities that are members of the ISG, and the Exchange or FINRA, on behalf of the Exchange, or both, may obtain trading information regarding trading the Shares and exchange-traded instruments from such markets and other entities. In addition, the Exchange may obtain information regarding trading in the Shares and exchange-traded instruments from markets and other entities that are members of ISG or with which the Exchange has in place a comprehensive surveillance sharing agreement.

The Adviser will make available daily to FINRA and the Exchange the Actual Portfolio of the Funds, upon request, in order to facilitate the performance of the surveillances referred to above.

In addition, the Exchange also has a general policy prohibiting the distribution of material, non-public information by its employees.

Proposed Commentary .03 to NYSE Arca Rule 8.601-E provides that the Exchange will implement and maintain written surveillance procedures for Active Proxy Portfolio Shares. As part of these surveillance procedures, the Investment Company's investment adviser will upon request by the Exchange or FINRA, on behalf of the Exchange, make available to the Exchange or FINRA the daily Actual Portfolio holdings of each series of Active Proxy Portfolio Shares. The Exchange believes that the ability to access the information on an as needed basis will provide it with sufficient information to perform the necessary regulatory functions associated with listing and trading series of Active Proxy Portfolio Shares on the Exchange, including the ability to monitor compliance with the initial and continued listing requirements as well as the ability to surveil for manipulation of Active Proxy Portfolio Shares.

The Exchange will utilize its existing procedures to monitor issuer compliance with the requirements of proposed Rule 8.601-E. For example, the Exchange will continue to use intraday alerts that will notify Exchange personnel of trading activity throughout the day that may indicate that unusual conditions or circumstances are present that could be detrimental to the maintenance of a fair and orderly market. The Exchange will require from the issuer of a series of Active Proxy Portfolio Shares, upon initial listing and periodically thereafter, a representation that it is in compliance with proposed Rule 8.601-E. The Exchange notes that proposed Commentary .01 to Rule 8.601-E would require an issuer of Active Proxy Portfolio Shares to notify the Exchange of any failure to comply with the continued listing requirements of proposed Rule 8.601-E. In addition, the Exchange will require funds to represent that they will notify the Exchange of any failure to comply with the terms of applicable exemptive and no-action relief. As part of its surveillance procedures, the Exchange will rely on the foregoing procedures to become aware of any non-compliance with the requirements of proposed Rule 8.601-E.

With respect to the Funds, all statements and representations made in this filing regarding (a) the description of the portfolio or reference asset, (b) limitations on portfolio holdings or reference assets, or (c) the applicability of Exchange listing rules specified in this rule filing shall constitute continued listing requirements for listing the Shares on the Exchange. The Exchange will obtain a representation from the Adviser, prior to commencement of trading in the Shares, that it will advise the Exchange of any failure by a Fund to comply with the continued listing requirements, and, pursuant to its obligations under Section 19(g)(1) of the Act, the Exchange will monitor for compliance with the continued listing requirements. If a Fund is not in compliance with the applicable listing requirements, the Exchange will commence delisting procedures under NYSE Arca Rule 5.5-E(m).

2. Statutory Basis

The Exchange believes that the proposed rule change is consistent with Section 6(b) of the Act, in general, and furthers the objectives of Section 6(b)(5) of the Act, in particular, in that it is designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general, to protect investors and the public interest.

With respect to the proposed listing and trading of Shares of the Funds, the Exchange believes that the proposed rule change is designed to prevent fraudulent and manipulative acts and practices in that the Shares will be listed and traded on the Exchange pursuant to the initial and continued listing criteria in proposed NYSE Arca Rule 8.601-E.

Each Fund's holdings will conform to the permissible investments as set forth in the American Century Application and the Exemptive Order and the holdings will be consistent with all requirements in the American Century Application and American Century Exemptive Order. Any foreign common stocks held by a Fund will be traded on an exchange that is a member of the ISG or with which the Exchange has in place a comprehensive surveillance sharing agreement.

Each Fund's investments will be consistent with its investment objective. Each Fund's investments, including derivatives, will be consistent with its investment objective and will not be used to enhance leverage (although certain derivatives and other investments may result in leverage). That is, a Fund's investments will not be used to seek performance that is the multiple or inverse multiple (e.g., 2X or -3X) of a Fund's primary broad-based securities benchmark index (as defined in Form N-1A).

The Exchange or FINRA, on behalf of the Exchange, or both, will communicate as needed regarding trading in the Shares and underlying exchange-traded instruments with other markets and other entities that are members of the ISG, and the Exchange or FINRA, on behalf of the Exchange, or both, may obtain trading information regarding trading in the Shares and exchange-traded instruments from such markets and other entities. In addition, the Exchange may obtain information regarding trading in the Shares and exchange-traded instruments from markets and other entities that are members of ISG or with which the Exchange has in place a comprehensive surveillance sharing agreement.

The Exchange, after consulting with various LMMs that trade ETFs on the Exchange, believes that market makers will be able to make efficient and liquid markets priced near the ETF's intraday value, and market makers employ market making techniques such as “statistical arbitrage,” including correlation hedging, beta hedging, and dispersion trading, which is currently used throughout the financial services industry, to make efficient markets in exchange-traded products. For Active Proxy Portfolio Shares, market makers may use the knowledge of a fund's means of achieving its investment objective, as described in the applicable fund registration statement, as well as a fund's disclosed Proxy Portfolio, to construct a hedging proxy for a fund to manage a market maker's quoting risk in connection with trading fund shares. Market makers can then conduct statistical arbitrage between their hedging proxy and shares of a fund, buying and selling one against the other over the course of the trading day. This ability should permit market makers to make efficient markets in an issue of Active Proxy Portfolio Shares without precise knowledge of a fund's underlying portfolio. This is similar to certain other existing exchange-traded products (for example, ETFs that invest in foreign securities that do not trade during U.S. trading hours), in which spreads may be generally wider in the early days of trading and then narrow as market makers gain more confidence in their real-time hedges.

The Funds will utilize the NYSE Proxy Portfolio Methodology that would allow market participants to assess the intraday value and associated risk of a Fund's Actual Portfolio and thereby facilitate the purchase and sale of Shares by investors in the secondary market at prices that do not vary materially from their NAV.

The daily dissemination of the identity and quantity of Proxy Portfolio component investments, together with the right of Authorized Participants to create and redeem each day at the NAV, will be sufficient for market participants to value and trade Shares in a manner that will not lead to significant deviations between the Shares' Bid/Ask Price and NAV.

With respect to Active Proxy Portfolio Shares generally, the pricing efficiency with respect to trading a series of Active Proxy Portfolio Shares will generally rest on the ability of market participants to arbitrage between the shares and a fund's portfolio, in addition to the ability of market participants to assess a fund's underlying value accurately enough throughout the trading day in order to hedge positions in shares effectively. Professional traders can buy shares that they perceive to be trading at a price less than that which will be available at a subsequent time and sell shares they perceive to be trading at a price higher than that which will be available at a subsequent time. It is expected that, as part of their normal day-to-day trading activity, market makers assigned to shares by the Exchange, off-exchange market makers, firms that specialize in electronic trading, hedge funds and other professionals specializing in short-term, non-fundamental trading strategies will assume the risk of being “long” or “short” shares through such trading and will hedge such risk wholly or partly by simultaneously taking positions in correlated assets or by netting the exposure against other, offsetting trading positions—much as such firms do with existing ETFs and other equities. Disclosure of a fund's investment objective and principal investment strategies in its prospectus and SAI should permit professional investors to engage easily in this type of hedging activity.

The proposed rule change is designed to promote just and equitable principles of trade and to protect investors and the public interest in that the Exchange will obtain a representation from the Funds that the NAV per Share of a Fund will be calculated daily and that the NAV, Proxy Portfolio and Actual Portfolio for each Fund will be made available to all market participants at the same time. Investors can obtain a Fund's SAI, shareholder reports, and its Form N-CSR, Form N-PORT and Form N-CEN. A Fund's SAI and shareholder reports will be available free upon request from a Fund, and those documents and the Form N-CSR, Form N-PORT and Form N-CEN may be viewed on-screen or downloaded from the Commission's website. In addition, with respect to each Fund, a large amount of information will be publicly available regarding the Funds and the Shares, thereby promoting market transparency. Quotation and last sale information for the Shares, ETFs, ETNs, U.S. exchange-traded common stocks, preferred stocks and ADRs will be available via the CTA high-speed line or from the exchange on which such securities trade. Price information for futures, foreign stocks and cash equivalents is available through major market data vendors. The website for the Funds will include a form of the prospectus for each Fund that may be downloaded, and additional data relating to NAV and other applicable quantitative information, updated on a daily basis. Trading in Shares of the Funds will be halted if the circuit breaker parameters in NYSE Arca Rule 7.12-E have been reached or because of market conditions or for reasons that, in the view of the Exchange, make trading in the Shares inadvisable. In addition, as noted above, investors will have ready access to the Proxy Portfolio and quotation and last sale information for the Shares. The Proxy Portfolio holdings for each Fund (including the identity and quantity of investments in the Proxy Portfolio) will be publicly available on the Funds' website before the commencement of trading in Shares on each Business Day. The Shares will conform to the initial and continued listing criteria under proposed Rule 8.601-E.

The Shares of the Funds will be subject to proposed Rule 8.601-E(d)(2)(D), which provides that the Exchange may consider all relevant factors in exercising its discretion to halt trading in a series of Active Proxy Portfolio Shares. Trading may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the series of Active Proxy Portfolio Shares inadvisable. These may include: (a) The extent to which trading is not occurring in the securities and/or the financial instruments composing the Proxy Portfolio and/or Actual Portfolio; or (b) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. If the Exchange becomes aware that the NAV, Proxy Portfolio or Actual Portfolio with respect to a series of Active Proxy Portfolio Shares is not disseminated to all market participants at the same time, the Exchange shall halt trading in such series until such time as the NAV, Proxy Portfolio or Actual Portfolio is available to all market participants at the same time.

The proposed rule change is designed to perfect the mechanism of a free and open market and, in general, to protect investors and the public interest in that it will facilitate the listing and trading of an additional type of actively-managed exchange-traded product that will enhance competition among market participants, to the benefit of investors and the marketplace. The Exchange will obtain a representation from the Adviser, prior to commencement of trading in the Shares of a Fund, that it will advise the Exchange of any failure by a Fund to comply with the continued listing requirements, and, pursuant to its obligations under Section 19(g)(1) of the Act, the Exchange will monitor for compliance with the continued listing requirements. If a Fund is not in compliance with the applicable listing requirements, the Exchange will commence delisting procedures under NYSE Arca Rule 5.5-E(m).

As noted above, the Exchange has in place surveillance procedures relating to trading in the Shares and may obtain information via ISG from other exchanges that are members of ISG or with which the Exchange has entered into a comprehensive surveillance sharing agreement. In addition, as noted above, investors will have ready access to information regarding quotation and last sale information for the Shares.

B. Self-Regulatory Organization's Statement on Burden on Competition

The Exchange does not believe that the proposed rule change will impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act. The Exchange believes the proposed rule change would permit listing and trading of another type of actively-managed ETF that has characteristics different from existing actively-managed and index ETFs and would introduce additional competition among various ETF products to the benefit of investors.

C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others

No written comments were solicited or received with respect to the proposed rule change.

III. Discussion and Commission Findings

After careful review, the Commission finds that the proposed rule change, as modified by Amendment No. 5, is consistent with the Act and rules and regulations thereunder applicable to a national securities exchange. In particular, the Commission finds that the proposed rule change, as modified by Amendment No. 5 is consistent with Section 6(b)(5) of the Act, which requires, among other things, that the Exchange's rules be designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general, to protect investors and the public interest. The Commission notes that in a separate order, it approved the Exchange's proposed rule change to adopt NYSE Arca Rule 8.601-E to permit the listing and trading of Active Proxy Portfolio Shares.

The Commission believes that the proposal is reasonably designed to promote fair disclosure of information that may be necessary to price the Shares appropriately and to prevent trading in the Shares when a reasonable degree of certain pricing transparency cannot be assured. As such, the Commission believes the proposal is reasonably designed to maintain a fair and orderly market for trading the Shares. The Commission also finds that the proposal is consistent with Section 11A(a)(1)(C)(iii) of the Act, which sets forth Congress's finding that it is in the public interest and appropriate for the protection of investors and the maintenance of fair and orderly markets to assure the availability to brokers, dealers, and investors of information with respect to quotations for, and transactions in, securities.

Specifically, the Commission notes that the Exchange, prior to commencement of trading in the Shares, will obtain a representation from the issuer of the Shares of each Fund that the NAV per Share will be calculated daily and that the NAV, Proxy Portfolio, and Actual Portfolio for each Fund will be made available to all market participants at the same time. Information regarding market price and trading volume of the Shares will be continually available on a real-time basis throughout the day on brokers' computer screens and other electronic services. Quotation and last-sale information for the Shares, ETFs, ETNs, U.S. exchange-traded common stocks, preferred stocks, and ADRs will be available via the Consolidated Tape Association high-speed line or from the exchange on which such securities trade. Price information for futures, foreign stocks and cash equivalents is available through major market data vendors. The Funds' website will include additional information updated on a daily basis, including, on a per Share basis for each Fund, the prior business day's NAV, the closing price or bid/ask price at the time of calculation of such NAV, and a calculation of the premium or discount of the closing price or bid/ask price against such NAV. The website will also disclose the percentage weight overlap between the holdings of the Proxy Portfolio compared to the Actual Portfolio holdings for the prior business day, and any other information regarding premiums and discounts and the bid/ask spread for a Fund as may be required for other ETFs under Rule 6c-11 under the 1940 Act. The Proxy Portfolio holdings for each Fund (including the identity and quantity of investments in the Proxy Portfolio) will be publicly available on the Funds' website before the commencement of trading in Shares on each Business Day and each Fund's website will disclose the information required under Rule 8.601-E(c)(3). The website and information will be publicly available at no charge.

In addition, the Exchange states that intraday pricing information for all constituents of the Proxy Portfolio that are exchange-traded, which includes all eligible instruments except cash and cash equivalents, will be available on the exchanges on which they are traded and through subscription services, and that intraday pricing information for cash equivalents will be available through subscription services and/or pricing services.

The Commission also notes that the Exchange's rules regarding trading halts help to ensure the maintenance of fair and orderly markets for the Shares. Specifically, pursuant to its rules, the Exchange may consider all relevant factors in exercising its discretion to halt trading in the Shares and will halt trading in the Shares under the conditions specified in NYSE Arca Rule 7.12-E. Trading may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Shares inadvisable, including (1) the extent to which trading is not occurring in the securities and/or the financial instruments composing the Proxy Portfolio and/or Actual Portfolio; or (2) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. Trading in the Shares also will be subject to NYSE Arca Rule 8.601-E(d)(2)(D), which sets forth additional circumstances under which trading in the Shares will be halted.

The Commission also believes that the proposal is reasonably designed to help prevent fraudulent and manipulative acts and practices. Specifically, the Exchange provides that:

• The Adviser is not registered as a broker-dealer but is affiliated with a broker-dealer and has implemented and will maintain a “fire wall” with respect to such broker-dealer affiliate regarding access to information concerning the composition of and/or changes to a Fund's Actual Portfolio and/or Proxy Portfolio;
• Any person related to the Adviser or a Fund who makes decisions pertaining to the Fund's Actual Portfolio and/or Proxy Portfolio or who has access to non-public information regarding a Fund's Actual Portfolio and/or the Proxy Portfolio or changes thereto are subject to procedures reasonably designed to prevent the use and dissemination of material non-public information regarding a Fund's Actual Portfolio and/or the Proxy Portfolio or changes thereto;
• In the event (a) the Adviser becomes registered as a broker-dealer or becomes newly affiliated with a broker-dealer or (b) any new adviser or sub-adviser is a registered broker-dealer, or becomes affiliated with a broker-dealer, it will implement and maintain a fire wall with respect to its relevant personnel or its broker-dealer affiliate regarding access to information concerning the composition of and/or changes to a Fund's Actual Portfolio and/or Proxy Portfolio, and will be subject to procedures designed to prevent the use and dissemination of material non-public information regarding a Fund's Actual Portfolio and/or Proxy Portfolio or changes thereto; and
• Any person or entity, including any service provider for a Fund, who has access to non-public information regarding a Fund's Actual Portfolio or the Proxy Portfolio or changes thereto will be subject to procedures reasonably designed to prevent the use and dissemination of material non-public information regarding a Fund's Actual Portfolio and/or the Proxy Portfolio or changes thereto, and if any such person or entity is registered as a broker-dealer or affiliated with a broker-dealer, such person or entity has erected and will maintain a “fire wall” between the person or entity and the broker-dealer with respect to access to information concerning the composition of and/or changes to a Fund's Actual Portfolio and/or Proxy Portfolio.

Finally, the Exchange represents that trading in the Shares will be subject to the existing trading surveillances, administered by the Exchange, as well as cross-market surveillances administered by FINRA on behalf of the Exchange, and that these surveillance procedures are adequate to properly monitor Exchange trading of the Shares in all trading sessions and to deter and detect violations of Exchange rules and federal securities laws applicable to trading on the Exchange.

The Exchange deems the Shares to be equity securities, thus rendering trading in the Shares subject to the Exchange's existing rules governing the trading of equity securities.

In support of this proposal, the Exchange represents that:

(1) The Shares will conform to the initial and continued listing criteria under NYSE Arca Rule 8.601-E.

(2) A minimum of 100,000 Shares for each Fund will be outstanding at the commencement of trading on the Exchange.

(3) The Exchange or FINRA, on behalf of the Exchange, or both, will communicate as needed, and may obtain information, regarding trading in the Shares and underlying exchange-traded instruments with other markets and other entities that are members of the ISG. In addition, the Exchange may obtain information regarding trading in the Shares and exchange-traded instruments from markets and other entities with which the Exchange has in place a comprehensive surveillance sharing agreement. Any foreign common stocks held by a Fund will be traded on an exchange that is a member of the ISG or with which the Exchange has in place a comprehensive surveillance sharing agreement.

(4) The Exchange has appropriate rules to facilitate transactions in the Shares during all trading sessions.

(5) For initial and continued listing, the Funds will be in compliance with Rule 10A-3 under the Act.

(6) Each Fund's holdings will conform to the permissible investments as set forth in the Application and Exemptive Order and the holdings will be consistent with all requirements set forth in the Application and Exemptive Order. Each Fund's investments, including derivatives, will be consistent with its investment objective and will not be used to enhance leverage (although certain derivatives and other investments may result in leverage).

(7) With respect to Active Proxy Portfolio Shares, all of the Exchange member obligations relating to product description and prospectus delivery requirements will continue to apply in accordance with Exchange rules and federal securities laws, and the Exchange and FINRA will continue to monitor Exchange members for compliance with such requirements.

The Exchange also represents that all statements and representations made in the filing regarding: (1) The description of the portfolios or reference assets; (2) limitations on portfolio holdings or reference assets; or (3) the applicability of Exchange listing rules specified in the filing constitute continued listing requirements for listing the Shares on the Exchange. In addition, the Exchange represents that the Exchange will obtain a representation from the Adviser, prior to commencement of trading in the Shares, that the Adviser will advise the Exchange of any failure by a Fund to comply with the continued listing requirements and, pursuant to its obligations under Section 19(g)(1) of the Act, the Exchange will monitor for compliance with the continued listing requirements. If a Fund is not in compliance with the applicable listing requirements, the Exchange will commence delisting procedures under NYSE Arca Rule 5.5-E(m).

The Commission finds good cause to approve the proposed rule change, as modified by Amendment No. 5, prior to the thirtieth day after the date of publication of notice of the filing of Amendment No. 5 in the Federal Register. In Amendment No. 5, the Exchange modified the description of each Fund and conformed the description of NYSE Arca Rule 8.601-E to the final rule approved in the Active Proxy Portfolio Shares Order. Amendment No. 5 also provides other clarifications and additional information related to the Funds. The changes and additional information in Amendment No. 5 assist the Commission in finding that the proposal is consistent with the Exchange Act. Accordingly, the Commission finds good cause, pursuant to Section 19(b)(2) of the Exchange Act, to approve the proposed rule change, as modified by Amendment No. 5, on an accelerated basis.

VI. Conclusion

It is therefore ordered, pursuant to Section 19(b)(2) of the Act that the proposed rule change (SR-NYSEArc-2019-96), as modified by Amendment No. 5, be, and it hereby is, approved on an accelerated basis.
