          - [Release No. 34-81437; File No. SR-BatsBZX-2017-34]

## I. Introduction

                    On May 5, 2017, Bats BZX Exchange, Inc. (the “Exchange” or “BZX”) filed with the Securities and Exchange Commission (the “Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) [1]                                          and Rule 19b-4 thereunder,[2]                                          a proposed rule change to adopt Bats Market Close, a closing match process for non-BZX listed securities. The Commission published notice of filing of the proposed rule change in the                     **Federal Register**                     on May 22, 2017.[3]                                          On July 3, 2017, 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 the proposed rule change should be disapproved.[4]                                          As of August 16, 2017, the Commission has received forty-six comment letters on the Exchange's proposed rule change, including a response from the Exchange.[5]                                          This order                           ( print page 40203)                        institutes proceedings under Section 19(b)(2)(B) of the Exchange Act [6]                                          to determine whether to approve or disapprove the proposed rule change.                

## II. Summary of the Proposed Rule Change

                    As described in more detail in the Notice, the Exchange proposes to introduce Bats Market Close, a closing match process for non-BZX listed securities. For non-BZX listed securities only, the Exchange's System [7]                                          would seek to match buy and sell Market-On-Close (“MOC”) [8]                                          orders designated for participation in Bats Market Close at the official closing price for such security published by the primary listing market.                

                    Members [9]                                          would be able to enter, cancel or replace MOC orders designated for participation in Bats Market Close beginning at 6:00 a.m. Eastern Time up until 3:35 p.m. Eastern Time (“MOC Cut-Off Time”).[10]                                          Members would not be able to enter, cancel or replace MOC orders designated for participation in the proposed Bats Market Close after the MOC Cut-Off Time.                

                    At the MOC Cut-Off Time, the System would match for execution all buy and sell MOC orders entered into the System based on time priority.[11]                                          Any remaining balance of unmatched shares would be cancelled back to the Member(s). The System would disseminate, via the Bats Auction Feed,[12]                                          the total size of all buy and sell orders matched per security via Bats Market Close. All matched buy and sell MOC orders would remain on the System until the publication of the official closing price by the primary listing market. Upon publication of the official closing price by the primary listing market, the System would execute all previously matched buy and sell MOC orders at that official closing price.[13] 

                    The Exchange would utilize the official closing price published by the exchange designated by the primary listing market in the case where the primary listing market suffers an impairment and is unable to perform its closing auction process.[14]                                          In addition, proposed Interpretation and Policy .03, specifies that up until the closing of the applicable securities information processor at 8:00 p.m. Eastern Time, the Exchange intends to monitor the initial publication of the official closing price, and any subsequent changes to the published official closing price, and adjust the price of such trades accordingly. If there is no initial official closing price published by 8:00 p.m. Eastern Time for any security, the Exchange would cancel all matched MOC orders in such security.                

                    The Exchange states that it is proposing to adopt Bats Market Close in response to requests from market participants, particularly buy-side firms,                           ( print page 40204)                        for an alternative to the primary listing markets' closing auctions that still provides an execution at a security's official closing price.[15]                                          Moreover, the Exchange contends that the proposal would not compromise the price discovery function performed by the primary listing markets' closing auctions because Bats Market Close would only accept MOC orders, and not limit orders, and the Exchange would only execute those matched MOC orders that naturally pair off and effectively cancel each other out.[16] 

## III. Summary of the Comments

                    As of August 16, 2017, the Commission has received forty-six comment letters on the proposal, including a response from the Exchange.[17]                                          Six commenters supported the proposal,[18]                                          and thirty-six commenters opposed the proposal.[19] 

                    Six commenters supported the proposal and stated that it would increase competition among exchanges for executions of orders at the close.[20]                                          These commenters asserted that increased competition could result in reduced fees for market participants.[21]                                          Three commenters characterized the primary listing markets as maintaining a “monopoly” on orders seeking a closing price with no market competition, which they argued has, and would continue to, result in a continual increase in fees for such orders if the proposal were not approved.[22]                                          In addition, IEX argued that the proposal does not unduly burden competition as exchanges often attempt to compete by adopting functionality or fee schedules developed by competitors.[23]                                          ViableMkts also asserted that the proposal is not fully competitive with closing auctions, as it does not accept priced orders or disseminate imbalance information.[24]                                          Rather, the proposal competes with other un-priced orders in closing auctions, which in its view, is not destructive to the mission of the closing auction.[25] 

                    In contrast, other commenters argued that the proposal would impede fair competition, including by “free-riding” on the investments the primary listing markets have made in their closing auctions.[26]                                          Specifically, NYSE asserted that the proposal is an unnecessary and inappropriate burden on competition as it would allow BZX to use the closing prices established through the auction of a primary listing market, without bearing any of the costs or risks associated with conducting a closing auction.[27]                                          NYSE added that the existing exchange fees for closing auctions reflect the value created by the primary listing exchange's complex procedures and technology to determine the official closing price of a security.[28]                                          NYSE emphasized that it has invested significantly in intellectual property and software to implement systems that facilitate orderly price discovery in the closing auction, as well as surveillance tools necessary to monitor activity leading up to, and in, the closing process.[29]                                          NYSE also noted that the proposal differs from the NASDAQ and NYSE Arca competing auctions in securities not listed on their exchanges in that such auctions compete on a level playing field because they do not rely on prices established by the primary listing exchange and they serve as an alternative method of establishing an official closing price if a primary listing exchange is unable to conduct a closing auction due to a technology issue.[30] 

                    NASDAQ also argued that the proposal would burden competition. Specifically, NASDAQ believed that the proposal undermines intra-market competition, by removing orders from NASDAQ's auction book and prohibiting those orders from competing on NASDAQ, which NASDAQ argued is necessary for the exchange to arrive at the most accurate closing price.[31]                                          NASDAQ also stated that, by diverting orders away from NYSE and NASDAQ, the proposal would detract from robust price competition and discovery that closing auctions ensure.[32]                                          NASDAQ further argued that in order for BZX to meaningfully enhance competition, it would have to generate its own closing price, as opposed to merely utilizing the closing price generated by a primary listing market.[33] 
      ( print page 40205)    
                    In addition, both NYSE and NASDAQ referenced the Commission's disapproval of NASDAQ's proposal to create a Benchmark Order as support that BZX has not sufficiently satisfied its obligation to justify that the proposal is consistent with the Act and not an inappropriate burden on competition. NYSE argued that BZX essentially proposes to compete with broker-dealer agency order matching services.[34]                                          NYSE asserted that the Commission disapproved NASDAQ's Benchmark Order, in part because it would provide an exchange with an unfair advantage over competing broker-dealers, which was not consistent with Section 6(b)(8) of the Act.[35]                                          NASDAQ further argued that the disapproval of its Benchmark Order proposal supports the assertion that an exchange must articulate how a proposed service is consistent with the policy goals of the Act with respect to national securities exchanges.[36] 

                    In response to commenters' contentions that the proposal would burden competition, BZX asserted that the proposal would enhance rather than burden competition.[37]                                          In this regard, BZX argued that its proposal would promote competition in the use of MOC orders at the official closing price.[38]                                          Further, it asserted that the Commission has approved the operation of competing closing auctions, noting in particular the closing auctions on NASDAQ, NYSE Arca, and the American Stock Exchange.[39]                                          BZX further argued that there is precedent for an exchange to execute orders solely at reference prices while not also displaying priced orders for that security.[40] 

                    BZX also argued that, rather than looking to compete with broker-dealer services, it is seeking to compete on price with the primary listing markets' closing auctions.[41]                                          In addition, BZX argued that, contrary to the assertions by NYSE and NASDAQ, its proposal does not implicate the same issues as NASDAQ's Benchmark Order proposal.[42] 

                    BZX also challenged the assertion that it was “free-riding” on the primary listing exchanges' closing auctions.[43]                                          In this regard, BZX argued that instead it was, on balance, providing a “a materially better value to the marketplace” in two ways: By not diverting price-forming limit orders away from the primary listing market; and by providing users with the official closing price because any other price would be undesirable to market participants and potentially harmful to price formation.[44] 

                    The majority of commenters addressed the potential impacts of the proposal on price discovery in the closing auctions on the primary listing markets. Seven commenters stated that the proposal would not negatively impact price discovery in the primary listing markets' closing auctions.[45]                                          These commenters asserted that because Bats Market Close would only execute paired MOC orders, and not limit-on-close orders, it would not impede the price discovery mechanisms of the primary listing markets' closing auctions. Three commenters referenced the current NASDAQ and NYSE Arca closing auction processes for securities listed on other exchanges, stating that these competing closing auction processes, which have been permitted by the Commission, may attract limit orders from the primary listing market and impede price discovery, unlike the BZX proposal which is limited to market orders.[46]                                          In addition, five commenters argued that, because BZX will publish the size of matched MOC orders in advance of the primary market's cut-off time, market participants would have available information needed to make further decisions regarding order execution and thus price discovery would not be impaired.[47]                                          Two commenters also asserted that many brokers already provide market-on-close pricing to customers through products that match orders internally, and the proposal may provide incentives for these brokers to send such orders to an exchange, thereby increasing transparency, reliability and price discovery at the close.[48] 

                    Thirty-two commenters stated that the proposal would further fragment the markets and harm price discovery in the closing auctions on the primary listing markets.[49]                                          For example, NASDAQ argued that BZX's MOC orders would be incapable of contributing to price discovery, and instead would further fragment the market by drawing orders and quotations away from primary closing auctions and undermine the mechanisms used to set closing prices.[50]                                          Specifically, NASDAQ expressed concern that the availability of Bats Market Close could cause a reduction in the number of limit-on-close orders                           ( print page 40206)                        submitted to the primary listing markets' closing auctions, which NASDAQ asserted would harm price discovery at the market close.[51]                                          Moreover, NASDAQ argued that even if the proposal only resulted in fewer market-on-close orders submitted to NASDAQ closing auctions, investors would be harmed because the official closing price could potentially represent a stale or undermined price.[52]                                          NASDAQ asserted that its closing cross is designed to maximize the number of shares that can be executed at a single price and that the number of market-on-close orders impacts the number of shares able to execute in a closing cross.[53]                                          Accordingly, NASDAQ argued that any attempt to divert trading interest, including market-on-close orders, from its closing auction would be detrimental to investors as it would inhibit NASDAQ's closing auction from functioning as intended and would negatively affect the quality of the official closing price.[54]                                          In addition, NASDAQ stated that it considered, but chose not to, disclose segmented information, such as matched MOC or LOC shares, for its closing auction in a piece-meal fashion, because NASDAQ believed it would lead to unintended consequences and undermine price discovery in the closing auction.[55] 

                    NYSE similarly argued that even though Bats Market Close would only accept MOC orders, it could materially impact official closing prices determined through a NYSE closing auction.[56]                                          First, NYSE emphasized the importance of the centralization of orders during the closing auction on the primary listing exchange, noting that it allows for investors to find contra-side liquidity and assess whether to offset imbalances, and for orders to be priced based on the true supply and demand in the market.[57]                                          NYSE explained that its designated market makers (“DMMs”), which have an obligation to facilitate the close of trading in their assigned securities, factor in the size of paired-off volume, and the composition of the closing interest, in assessing the appropriate closing price.[58]                                          NYSE asserted that under the proposal, DMMs would lose full visibility into the size and composition of MOC interest, and thus would likely have to make more risk-adverse closing decisions, resulting in inferior price formation.[59] 

                    Second, NYSE argued that the proposal would also detrimentally impact price discovery on the NYSE Arca and NYSE American automated closing auctions. NYSE stated that in the last six months there were 130 instances where the official closing price determined through a NYSE Arca closing auction was based entirely on paired-off market order volume.[60]                                          In those instances, pursuant to NYSE Arca rules, the official closing price is the midpoint of the auction NBBO as of the time the auction is conducted. NYSE stated that if all market orders for a NYSE Arca listed security were sent to BZX, the official closing price would instead be the consolidated last sale price, which can differ from the midpoint of the auction NBBO by as much as 3.2%.[61] 

                    Several other commenters similarly explained how the proposal may impact the integrity of official closing prices. In particular, GTS, a DMM on NYSE, argued that market-on-close orders are a vital component of closing prices and, should those orders be diverted away from the primary listing markets as a result of the proposal, it could undermine the official closing prices.[62]                                          Multiple commenters stated that one of the benefits of a centralized closing auction conducted by the primary listing market is that it allows market participants to fairly assess supply and demand such that the closing prices reflect both market sentiment and total market participation.[63]                                          Because the proposal may cause orders to be diverted away from the primary listing exchanges, these commenters argued that it would negatively affect the reliability and value of closing auction prices.                

                    Some commenters further argued that because the proposal undermines the reliability of the closing process and/or the official closing price it also poses a risk to listed companies and its shareholders.[64]                                          In addition, one commenter, SPDJI, argued that the proposal may also impact confidence in the pricing of benchmark indices as confidence in closing prices is a prerequisite for market participants to maintain confidence in the pricing of benchmark indices.[65]                                          Accordingly, SPDJI asserted that because the closing price is a critical data point for investors, great caution should be taken in any changes to the closing auction.[66] 

                    Moreover, some commenters argued that the centralization of liquidity at the open and close of trading, and how primary listing markets perform during the opening and closing, are important factors for issuers in determining where to list their securities, and the additional risk posed to listed                           ( print page 40207)                        companies from an unreliable or unrepresentative closing price and/or process could impact an issuer's decision where to list and/or cause companies to forgo going public.[67] 

                    In response to concerns regarding the impact of the proposal on the price discovery process, BZX argued that, because the proposal would only match MOC orders and would require the Exchange to publish the number of matched shares in advance of the primary listing markets' cut-off times, BZX believes it would avoid any impact on price discovery.[68]                                          In addition, BZX offered to disseminate more information with regard to Bats Market Close and to disseminate such information via the applicable securities information processor, in addition to the Bats Auction Feed.[69]                                          BZX further challenged commenters' concerns that Bats Market Close could pull all MOC orders away from the primary listing markets and alter the calculation of the closing price, noting that such a scenario could occur today as a result of competing closing auctions and broker-dealers that offer internal MOC order matching solutions.[70]                                          Furthermore, BZX argued that the competing auctions run by NASDAQ and NYSE Arca could not only pull all MOC interest away from the primary listing markets but could also divert all price-setting limit-on-close interest from those markets as well.[71]                                          BZX also asserted that such competing closing auctions often may produce bad auction prices on the non-primary market, as compared to the proposed Bats Market Close which would ensure that market participants receive the official closing price.[72]                                          Accordingly, BZX contends that the proposal would not impose fragmentation on the market at the close that does not already exist today.[73] 

                    In response to NYSE's arguments regarding the impact on a DMM's ability to price the close, BZX argued that this point highlights what it believes to be an additional benefit of allowing it to compete with NYSE's closing auction.[74]                                          Specifically, BZX argued that its proposal would provide an alternative liquidity pool that would allow users to avoid the “subjective decision making of the DMMs.” [75] 

                    With regard to concerns about the impact of the proposal on issuers and their shareholders, BZX reaffirmed that the proposal is designed not to impact the trading environment for issuers and their securities or the price discovery function of the primary listing markets' closing auction.[76] 

                    In arguing that the proposal would cause fragmentation and thus impair the closing price, NYSE and NASDAQ also asserted that the proposal contradicts the Commission's approval of recent amendments to the National Market System Plan to Address Extraordinary Market Volatility (the “LULD Plan”) which, they argue, centralize re-opening auction liquidity at the primary listing exchange by prohibiting other market centers from re-opening following a trading pause until the primary listing exchange conducts a re-opening auction.[77]                                          Specifically, these commenters asserted that it would be inconsistent for the Commission to find it in the public interest to consolidate trading in a re-opening auction, while sanctioning fragmentation of trading in a closing auction.[78] 

                    In response, BZX argued that this comparison is misplaced.[79]                                          Specifically, BZX said the amendment to the LULD Plan cited by NYSE and NASDAQ granted the primary listing market the ability set the re-opening price but did not mandate the consolidation of orders at the primary listing market following a trading halt.[80]                                          Accordingly, BZX believes the proposal is consistent with the LULD Plan as it seeks to avoid producing a “bad” or “outlier” closing price and does not affect the centralization of price-setting closing auction orders.[81] 

                    Several commenters addressed the potential impact of the proposal on market complexity and operational risk as a result of increased market fragmentation. Some of these commenters believed that the proposal would not introduce significant additional complexity or operational risk. For example, two commenters argued that the proposal could enhance the resiliency of the closing auction process by providing market participants an additional mechanism through which to execute orders at the official closing price in the event of a disruption at a primary listing market.[82]                                          Another commenter argued that exchanges already have many market data feeds that firms must purchase to ensure that they have all of the information necessary to make informed execution decisions and that adding another data feed will not add complexity given the small amount of information that goes into the closing data feed and the current capabilities of market participants to re-aggregate multiple data feeds.[83] 

                    In contrast, other commenters argued that the proposal would add unnecessary market complexity and operational risk. In particular, two commenters noted that the proposal would require market participants to monitor an additional data feed, the Bats Auction Feed, one noting that if additional exchanges adopted similar functionality to Bats Market Close, it would require monitoring of even more data feeds.[84]                                          These commenters argued that monitoring an additional data feed could increase operational risk by creating another point of failure at a                           ( print page 40208)                        critical time of the trading day.[85]                                          One commenter also noted the increased complexity involved in sending order flow to more than one exchange in short periods of time near the close of the trading day.[86]                                          This commenter argued that the proposal increases operational risk and complexity at a critical point of the trading day by forcing market participants whose orders did not match in Bats Market Close to quickly send MOC orders from one exchange to another before the cut-off time at the primary market closing auction.[87]                                          This added complexity, GTS argued, puts additional stress on the systems of exchanges and increases the potential for disruptions.[88]                                          Lastly, two commenters argued that the proposal could encourage other exchanges, broker-dealers, and alternative trading systems to offer similar processes, which would introduce undesirable fragmentation to the market and lead to operational challenges for investors and traders.[89] 

                    In response, BZX argued that the proposal would not increase operational risks, but rather would provide a way to address the single point of failure risk that exists for closing auctions conducted on the primary listing markets.[90]                                          BZX argued that despite the current system of designated auction backups, market participants can be confused about whether an exchange is in fact able to conduct a closing auction.[91]                                          BZX believes Bats Market Close could provide an alternative option for market participants to route orders, in the event there is an impairment at the primary listing market, and still receive the official closing price.[92] 

                    In addition, as noted above, BZX stated that it would be willing to disseminate information regarding matched MOC orders, not only via the Bats Auction Feed, but also via the applicable securities information processor, if permissible.[93]                                          BZX added that modern software can easily and simply add volume data disseminated by the primary listing markets regarding the closing auction and data regarding matched MOC orders from the Bats Market Close.[94] 

                    Several commenters addressed the issue of whether the proposal would facilitate manipulation of both the closing auctions on the primary listing markets, as well as continuous trading during the final minutes of the trading day. Some commenters did not believe it would do so. For example, one commenter noted that incentives to manipulate the closing price already exist and it is unlikely the proposal would result in increased manipulation of the market close.[95]                                          In addition, IEX argued that the proposal would make manipulation of closing crosses more conspicuous.[96]                                          IEX also claimed that the Consolidated Audit Trail would provide a new tool for detecting any such manipulation.[97] 

                    In contrast, several commenters asserted that the proposal raises a risk of manipulation, in part due to the asymmetry of information that would be disseminated, which would allow market participants to utilize informational advantages to their own benefit. For example, NASDAQ argued that information concerning the amount of orders matched through Bats Market Close, would represent tradable information that market participants could use to “game” the closing crosses on the primary listing markets and undermine fair and orderly markets.[98]                                          In particular, NASDAQ argued that its closing auction was designed to carefully balance the amount and timing of data released so as to reduce the risk of gaming, but that this new information regarding paired MOC orders could be used to gauge the depth of the market, the direction of existing imbalances, and the likely depth remaining at NASDAQ, creating gaming opportunities.[99]                                          NYSE similarly argued that the proposal would increase potential manipulation.[100]                                          First, NYSE asserted that the potential for manipulative activity at the close would increase because primary listing exchange auctions would decrease in size and thus be easier to manipulate.[101]                                          NYSE also argued that the proposal facilitates manipulative activity by providing an incentive for market participants to inappropriately influence the closing price when they know they have been successfully paired-off on BZX.[102]                                          NYSE further asserted that the proposal could potentially provide some market participants, such as professional traders, with useful information that other market participants do not have, such as the direction of an imbalance, which could be used to influence the official closing price.[103] 

                    Although not citing concerns regarding manipulation specifically, T. Rowe Price similarly argued that the proposal would lead to information asymmetries that could result in changes in continuous trading behavior leading into the market close as some market participants could be trading on information gathered from Bats Market Close pairing results.[104]                                          T. Rowe Price asserted that a market participant that is aware of the composition of volume paired through Bats Market Close at 3:35 p.m. would be in a position to use that information to influence its trading behavior over the next ten to fifteen minutes leading in to the closing auction cut-off times on NYSE and NASDAQ respectively.[105]                                          T. Rowe Price argued that, as a result, the proposal could not only impact price discovery in closing auctions on the primary listing markets it could also impact continuous trading behavior.[106] 

                    NYSE also stated that identifying manipulative activity would also become more difficult under the proposal due to the time difference between the Bats Market Close and primary market closing auctions and the cross-market nature of the manipulation.[107]                                          GTS similarly argued that the proposal would make surveillance of the market close more difficult and expensive due to                           ( print page 40209)                        fragmentation of order flow across multiple markets.[108] 

                    In response, BZX argued that it does not believe that the proposal creates a potential for increased manipulation.[109]                                          Should the Commission approve the proposal, BZX notes that both it and FINRA as well as other exchanges would continue to surveil for manipulative activity and “seek to punish those that engage in such behavior.” [110]                                          Furthermore, BZX argued that information asymmetries are inherent in trading, including the primary listing markets closing auctions.[111]                                          For example, BZX argued that the current operation of d-Quotes on NYSE carries a risk of manipulation as it provides an informational advantage to NYSE DMMs and floor brokers, and allows d-Quotes to be entered, modified or cancelled up until 3:59:50 p.m. while other market participants are prohibited from entering, modifying or cancelling on-close orders after 3:45 p.m.[112]                                          Lastly, BZX argued that the information disseminated through the Bats Auction Feed would not provide an indication of whether the cancelling of a particular side of an order is meaningful, which limits its potential to impact the official closing price.[113] 

                    Several commenters also addressed the potential impacts of the proposal on market participants that they assert play important roles in facilitating closing auctions on NYSE. Specifically, three commenters asserted that the proposal would have potentially detrimental impacts on NYSE floor brokers.[114]                                          Eighteen commenters asserted that the proposal would make it more difficult for Designated Market Makers to facilitate an orderly close of NYSE listed securities as they would lose the ability to continually assess the composition of market-on-close interest.[115]                                          Many of these commenters that are issuers asserted that one of the reasons they chose to list on NYSE was the ability to have access to a DMM that is responsible for facilitating an orderly closing auction.[116] 

                    Several commenters stated that the proposal could harm issuers, particularly small and mid-cap companies.[117]                                          Many of these commenters, some of which are issuers, stated that the current centralized closing auctions on the primary listing markets contribute meaningful liquidity to a company's stock, facilitates investment in the company, and helps to lower the cost of capital. Accordingly, these commenters expressed concern that potential fragmentation caused by the proposal could negatively impact liquidity during the closing auction, causing detrimental effects to listed issuers.[118]                                          Several commenters further argued that centralized closing auctions provide better opportunities to fill large orders with relatively little price impact.[119] 

                    In contrast, one commenter argued that the proposal would improve aggregate liquidity at the official closing price.[120]                                          Specifically, this commenter asserted that the lower aggregate cost of trading would likely spur incremental increases in trading volumes.[121]                                          In addition, this commenter stated that the ability to enter MOC orders into Bats Market Close with little risk of information leakage may attract an additional source of liquidity.[122] 

                    Finally, some commenters identified areas that they believed were not adequately addressed by the proposal and/or made suggestions for modifications to the Exchange's proposal. For example, one commenter suggested that BZX extend the proposed MOC Cut-Off Time to closer to the primary market close.[123]                                          Another commenter suggested that, as an alternative, NYSE and NASDAQ should voluntarily review and reduce their auction fee structures, or, alternatively, the Commission should impose a cap on transaction fees for closing auctions.[124]                                          Lastly, NASDAQ also noted several areas, or scenarios, that it believed were not adequately explained by the proposal.[125] 

## IV. Proceedings To Determine Whether To Approve or Disapprove the BZX Proposal

                    The Commission hereby institutes proceedings pursuant to Section 19(b)(2) of the Act [126]                                          to determine whether the Exchange's proposed rule change should be approved or disapproved. Further, pursuant to Section 19(b)(2)(B) of the Act,[127]                                          the Commission is hereby providing notice of the grounds for disapproval under consideration. The Commission believes it is appropriate to institute proceedings at this time in view of the legal and policy issues raised by the proposal. Institution of proceedings does not indicate, however, that the Commission has reached any                           ( print page 40210)                        conclusions with respect to any of the issues involved.                

                    In particular, the Commission is instituting proceedings to allow for additional analysis of the proposed rule change's consistency with: (1) Section 6(b)(5) of the Act which requires, among other things, that the rules of a national securities exchange 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;” [128]                                          and (2) Section 6(b)(8) of the Act, which requires that the rules of a national securities exchange “not impose any burden on competition not necessary or appropriate in furtherance of the purposes of [the Act].” [129] 

As described above, BZX proposes to introduce Bats Market Close, a closing match process for non-BZX listed securities that would match MOC orders submitted to the Bats Market Close at the official closing price for such security published by the primary listing market. Under the proposal, Members would be able to submit, cancel, and replace MOC orders designated for the Bats Market Close up until the MOC Cut-Off Time at 3:35 p.m., after which time orders would be matched for execution and any remaining imbalance would be cancelled back to the Member(s). BZX would disseminate, via the Bats Auction Feed, the total size of all buy and sell orders matched for each security. The Exchange asserts that its proposal would increase competition and decrease fees for market participants, without impacting the price discovery process.

                    The Commission has consistently recognized the importance of closing auctions of the primary listing markets. For example, in its adoption of Regulation SCI, the Commission identified systems used to support closings on the primary market as “critical SCI systems,” stating that “reliable . . . closings on the primary listing markets are key to the establishment of fair and orderly markets,” and noting that “closing auctions at the primary listing markets attract widespread participation, and the closing prices they establish are commonly used as benchmarks.” [130]                                          Accordingly, the Commission is considering whether the proposal removes impediments to and perfects the mechanism of a free and open market and a national market system, and what its impact would be on the primary listing markets' closing auctions, including their important price discovery functions, or the reliability and integrity of the closing prices that they establish. Further, the Commission is considering whether the proposal imposes any burden on competition not necessary or appropriate in furtherance of the purposes of the Act, including the potential competitive burdens that may be created when an exchange offers market participants the ability to execute orders at a lower cost at the closing price established by another exchange, without incurring the costs of developing and operating the closing auctions from which the price is derived. In addition, the Commission is considering whether the proposal is designed to prevent fraudulent and manipulative acts and practices and, in particular, whether it would provide increased incentives or opportunities for inappropriate utilization of information to manipulate the closing price. Finally, the Commission is considering whether the proposal would have additional impacts on the markets, including increased complexity and operational risk, that would be inconsistent with the protection of investors and the public interest.                

## V. Commission's Solicitation of Comments

                    The Commission requests that interested persons provide written submissions of their views, data, and arguments with respect to the issues identified above, as well as any other relevant concerns they may have with the proposal. In particular, the Commission invites the written views of interested persons concerning whether the proposal is consistent with Sections 6(b)(5) and 6(b)(8) of the Act, or any other provision of the Act or rule or regulation thereunder. Although there do not appear to be any issues relevant to approval or disapproval which would be facilitated by an oral presentation of views, data, and arguments, the Commission will consider, pursuant to Rule 19b-4, any request for an opportunity to make an oral presentation.[131] 

                    Such comments should be submitted by September 14, 2017. Rebuttal comments should be submitted by September 28, 2017. The Commission asks that commenters address the sufficiency and merit of the Exchange's statements in support of the proposal, which are set forth in the Notice,[132]                                          in addition to any other comments they may wish to submit about the proposed rule change. In particular, the Commission seeks comment, including, where relevant, any specific data, statistics, or studies, on the following:                

1. Would the proposed rule change affect price discovery in the closing auction process on each primary listing exchange? If so, how? Would any such impact be the same at each of the primary listing exchanges? What information do market participants need going into the closing auction? Would the proposed rule change affect the information available to market participants during the closing auction process? If so, how? If commenters believe the proposal would harm price discovery in the closing auction process, to the extent possible please provide specific data, analyses, or studies for support.

                    2. To what extent, if at all, would the availability of the Bats Market Close impact market participants' use of limit-on-close orders in the closing auction processes on the primary listing exchanges, including with respect to size and price? Please explain. Would market participants use MOC orders in the Bats Market Close as a substitute for using limit orders to participate in the closing auction processes at the primary listing exchanges? Would any such impacts be the same for each of the primary listing exchanges? Are there differences between the closing auction processes at each of the primary listing exchanges whereby the proposed Bats Market Close would have differing effects on each primary listing exchange? If so, please explain. How does information available in the closing auction process affect market participants' order submissions and/or determination of the closing price? Would the proposed rule change affect market participants' trading strategies in closing auctions? If so, how? If commenters believe the proposal would impact the use of limit-on-close orders in closing auctions, to the extent possible please provide specific data, analyses, or studies for support.                          ( print page 40211)    

3. What analyses of available data could provide information about relationships between information disseminated during closing auctions, trading strategies in closing auctions, and closing prices? How would such analyses help estimate the impact, if any, of any changes in the availability of information under the proposed rule change on trading strategies and closing prices? In this regard, to the extent possible, please provide specific data, analyses, or studies in support.

                    4. What amount of trading volume at the close occurs on venues other than the primary listing exchanges (such as competing closing auctions and/or broker-dealer internal matching processes for MOC orders) and how does such closing volume compare with that of the primary listing exchanges? How does that volume impact the closing auction process on each of the primary listing exchanges? If commenters believe the proposal would impact volume in the closing auction process, to the extent possible please provide specific data, analyses, or studies for support. How does the Bats Market Close proposal differ from such existing processes (                    *i.e.,*                     competing closing auctions and/or broker-dealer internal MOC matching processes)? Would the proposal affect the existing level of fragmentation in the market? If so, how? Please describe. Would the proposal impact the aggregate liquidity at the primary listing markets during the closing auctions? If so, how? If commenters believe the proposal would impact the existing level of fragmentation in the market or aggregate liquidity at the primary listing markets during the closing auction, to the extent possible please provide specific data, analyses, or studies for support. Would the matching of a significant amount of MOC orders at a venue other than the primary listing market affect the integrity or reliability of the official closing auction and the resulting closing price? If so, how? Please describe in detail and provide examples if possible. Further, if commenters believe the proposal would affect the integrity or reliability of the official closing auction and the resulting closing price, to the extent possible please provide specific data, analyses, or studies for support.                

5. Would the proposal have a positive, negative, or neutral impact on competition? Please explain. How would any impact on competition from the proposal benefit or harm the national market system and/or the various market participants? Please describe and explain how, if at all, aspects of the national market system and/or different market participants would be affected. What are the current costs associated with a primary listing market developing and operating a closing auction, and to what extent (and if so, how) are these costs passed on to market participants today? How do the fixed costs associated with developing closing auctions compare to the variable costs of conducting closing auctions? How do the revenues collected from closing auctions compare to these costs? Would the proposal impact the current fees charged by the primary listing markets for participation in their closing auctions? If so, how? If commenters believe the proposal would impact competition, to the extent possible please provide specific data, analyses, or studies for support.

6. What effect would the proposal have on market complexity and/or operational risk, if any? If commenters believe the proposal would impact market complexity and operational risk, to the extent possible, please provide specific data, analyses, or studies for support. Would the daily process of cancelling unmatched MOC orders back to members so that they can be routed to the primary listing markets before the closing auction cut-off times create operational or other risks for the markets or market participants? If so, please describe. Would any such risks be different than the risks that currently exist now for market participants? Are there alternative ways of managing unmatched orders that would have different implications for the operational risks of the proposal? If so, please describe. Would the monitoring of an additional data feed be difficult or increase risk for market participants? Why or why not?

7. Would the proposal affect the potential for manipulation and, if so, what types of manipulative activity might result from, or be decreased by, the proposal? Would the proposal create informational advantages for certain market participants? If so, please detail these advantages and describe whether and how such information could be utilized to a market participant's own advantage. Would such informational advantages differ from information asymmetries that exist in the markets today? If so, please describe. Would the proposal affect surveillance for manipulation negatively or positively, and are existing surveillance tools adequate to monitor any increased risk? Please explain. If commenters believe the proposal would increase or decrease the potential for manipulative activity, to the extent possible please provide specific data, analyses, or studies for support.

8. What are the potential impacts of the proposal for listed issuers? For example, would the proposal impact the liquidity of an issuer's stock? If so, how? Would the proposal affect an issuer's decision as to whether to list their securities on a national securities exchange? If so, how? Would any impacts of the proposal affect small and mid-sized listed companies differently from larger listed companies? If so, please describe how. What other impacts, if any, could the proposal have on various other market participants, such as market makers and floor brokers, and in particular, their roles in the closing? If commenters believe the proposal would impact listed issuers or other market participants, to the extent possible please provide specific data, analyses, or studies for support.

11.                             As set forth in proposed Interpretation and Policy .02, the Exchange would cancel all MOC orders designated to participate in Bats Market Close in the event the Exchange becomes impaired prior to the MOC Cut-Off Time and is unable to recover within 5 minutes from the MOC Cut-Off Time. The Exchange states that this would provide Members time to route their orders to the primary listing market's closing auction. Should the Exchange become impaired after the MOC Cut-Off Time, proposed Interpretation and Policy .02 states that it would retain all matched MOC orders and execute those orders at the official closing price once it is operational.

The Exchange also represented that it intends for such fee to remain lower than the fee charged by the applicable primary listing market.                         *See id.*

In addition, one commenter urged the Commission to conduct a close analysis of the proposal and stated that if the Bats proposal would seriously degrade the quality of the closing price, then it should be rejected.                         *See*                         Angel Letter,                         *supra*                         note 5. Other commenters expressed concern that the proposal could disrupt the closing auction process on the primary listing markets and asked the Commission to carefully consider the impacts of the proposal and whether such impacts would be necessary and helpful to public companies.                         *See*                         Duffy/Meeks Letter,                         *supra*                         note 5, at 1-2.

In addition, in response to NASDAQ's contention that it is aware of no regulator in any jurisdiction that has sanctioned a diversion of orders from the primary market close, BZX noted the Ontario Securities Commission's approval of a similar proposal by Chi-X Canada ATS, which it said is currently owned by NASDAQ, to match MOC orders at the closing price established by the Toronto Stock Exchange.                         *See*                         NASDAQ Letter,                         *supra*                         note 5, at 10; BZX Letter,                         *supra*                         note 5, at 7 (stating that the Ontario Securities Commission stated that the proposal would not threaten the integrity of the price formation process and would pressure the Toronto Stock Exchange to competitively price executions during their closing auction).

BZX provided evidence of 14 instances in June 2017 where a NASDAQ-listed security had no volume in NASDAQ's closing auction but did have volume in NYSE Arca's closing auction.                         *See id.*                         In response, NYSE argued that it believed it was misleading to compare the proposal to the competing closing auctions because BZX would be offering neither a competing closing auction nor a facility to establish the official closing price should a primary listing exchange invoke its closing auction contingency plan.                         *See*                         NYSE Letter 2,                         *supra*                         note 5, at 3.

Furthermore, NYSE argued that in certain situations, investors may not be able to participate in a closing auction on NYSE American or NYSE Arca if they wait until after their order was cancelled by BZX to send in a market-on-close order to closing auctions on NYSE Arca and NYSE American. NYSE explained that in situations where there is an order imbalance priced outside the Auction Collars, orders on the side of the imbalance are not guaranteed to participate in the closing auctions on those two exchanges. Earlier submitted market-on-close orders have priority.                         *See*                         NYSE Letter 1,                         *supra*                         note 5, at 8.

Specifically, NASDAQ provides several scenarios to illustrate areas in which it believes how the Bats Market Close would operate is unclear, including where: (1) NASDAQ does not conduct a closing cross; (2) the official closing price for a NASDAQ-listed security is the consolidated last sale price, which is an inferior price to the NBBO at 4:00 p.m.; and (3) the official closing price would trade through the Bats resting limit order book. In addition, NASDAQ argues that BZX did not adequately explain how it would avoid using a possibly “stale” price if there were no orders and thus no auction on a primary listing market, but there were MOC orders in Bats Market Close.
