September 5, 2019.
Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”),
and Rule 19b-4 thereunder,
notice is hereby given that on August 23, 2019, Cboe Exchange, Inc. (the “Exchange” or “Cboe Options”) filed with the Securities and Exchange Commission (the “Commission”) the proposed rule change as described in Items I, II, and III below, which Items have been prepared by the Exchange. The Exchange filed the proposal as a “non-controversial” proposed rule change pursuant to Section 19(b)(3)(A)(iii) of the Act 
and Rule 19b-4(f)(6) thereunder.
The Commission is publishing this notice to solicit comments on the proposed rule change from interested persons.
I. Self-Regulatory Organization's Statement of the Terms of Substance of the Proposed Rule Change
The Exchange proposes to amend the Exchange's Rules regarding routing services, including the Hybrid Agency Liaison (“HAL”) system, and move those Rules from the currently effective Rulebook (“current Rulebook”) to the Start Printed Page 47978shell structure for the Exchange's Rulebook that will become effective upon the migration of the Exchange's trading platform to the same system used by the Cboe Affiliated Exchanges (as defined below) (“shell Rulebook”). The text of the proposed rule change is provided in Exhibit 5.
The text of the proposed rule change is also available on the Exchange's website (http://www.cboe.com/AboutCBOE/CBOELegalRegulatoryHome.aspx), at the Exchange's Office of the Secretary, and at the Commission's Public Reference Room.
II. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change
In its filing with the Commission, the Exchange 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 these 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 aspects of such statements.
A. Self-Regulatory Organization's Statement of the Purpose of, and the Statutory Basis for, the Proposed Rule Change
In 2016, the Exchange's parent company, Cboe Global Markets, Inc. (formerly named CBOE Holdings, Inc.) (“Cboe Global”), which is also the parent company of Cboe C2 Exchange, Inc. (“C2”), acquired Cboe EDGA Exchange, Inc. (“EDGA”), Cboe EDGX Exchange, Inc. (“EDGX” or “EDGX Options”), Cboe BZX Exchange, Inc. (“BZX” or “BZX Options”), and Cboe BYX Exchange, Inc. (“BYX” and, together with Cboe Options, C2, EDGX, EDGA, and BZX, the “Cboe Affiliated Exchanges”). The Cboe Affiliated Exchanges are working to align certain system functionality, retaining only intended differences, between the Cboe Affiliated Exchanges, in the context of a technology migration. Cboe Options intends to migrate its trading platform to the same system used by the Cboe Affiliated Exchanges, which the Exchange expects to complete on October 7, 2019. In connection with this technology migration, the Exchange has a shell Rulebook that resides alongside its current Rulebook, which shell Rulebook will contain the Rules that will be in place upon completion of the Cboe Options technology migration.
The Exchange proposes to harmonize its rules in connection with routing functions on the Exchange to that of the Cboe Affiliated Exchanges. Specifically, the Exchange proposes to update and amend current Rule 6.14A, which governs the operation of the HAL system to be consistent with of the corresponding rule of EDGX Options, Rule 21.18, which governs the operation of the Step Up Mechanism (“SUM”). The Exchange also proposes to harmonize Rule 6.6A, Rule 6.14B, and Rule 6.14C with that of its affiliate option exchange, C2, Rule 6.15, as well as EDGX and BZX Rule(s) 21.9, which provide for order routing rules of the exchange. The Exchange proposes these amendments to reflect the routing functions rule language of the Cboe Affiliated Exchange rules, retaining only slight differences regarding Exchange-specific language/definitions. In conforming its routing rules to that of the Cboe Affiliated Exchanges' rules, the Exchange proposes few substantive changes, namely amending the rules to allow for all Users 
to respond to a SUM (the Exchange proposes to rename HAL as SUM, and refers to SUM herein) exposure message, to allow a User to opt out of having its exposed order routed to other exchanges at the conclusion of a SUM exposure period, to update the scenarios in which a SUM auction will terminate early (which includes incorporating provisions that account for All-or-None orders), and, finally, to adopt the order routing functionality currently in place on the Cboe Affiliated Exchanges.
The Exchange also proposes to make non-substantive changes to simplify, clarify, and generally update its routing rules by consolidating its routing provisions into a single rule, simplify rule language, update the rule text to read in plain English, reformat the paragraph lettering and/or numbering, and update cross-references to rules not yet in the shell Rulebook but that will be in the shell Rulebook and implemented upon migration.
Proposed Rule 5.35
Current Rule 6.14A governs the operation of HAL. SUM is the EDGX Options equivalent of the Exchange's HAL. Both systems allow for orders not automatically executed by the respective exchange to “step up” to meet the NBBO in order to interact with orders sent to the Exchange. Both rules govern the current handling of orders eligible for such automatic handling, which include (i) an order that is marketable against the Exchange's disseminated quotation (the “BBO”, as specifically defined in the Exchange's Rules) while not the NBBO and (ii) an order that would improve the BBO and that is marketable against quotations disseminated by other exchanges (the “ABBO”) that are participants in the Options Order Protection and Locked/Crossed Plan (the “Linkage Plan”).
In anticipation of migration, the Exchange proposes to move Rule 6.14A to proposed Rule 5.35 (and subsequently delete Rule 6.14A upon migration) and amend the current provisions under Rule 6.14A to be consistent with EDGX Option's corresponding Rule 21.18. This includes renaming “HAL” to be called “SUM”, which, as stated, is a substantially similar system for processing orders not automatically executed by the respective exchanges. The automatic handling systems across the affiliated exchanges will function in a substantively identical manner upon migration, therefore updating HAL to be called SUM will mitigate any potential investor confusion and provide for uniform rules regarding the same functionality.
Currently on HAL, pursuant to Rule 6.14A(b), only Market-Makers with an appointment in the relevant option class and Trading Permit Holders (“TPHs”) acting as agent for orders resting at the top of the Book in the relevant option series opposite the order submitted to HAL may submit responses to the exposure message during the exposure period (unless the Exchange determines, on a class-by-class basis, to allow all TPHs to submit responses to the exposure message). The proposed rule change updates this provision to align with the manner in which SUM responses function on EDGX Options; all Users may submit responses to the exposure message during the exposure period.
The Exchange currently allows all TPHs to respond to all classes during the exposure period, therefore this change does not change or impact the manner in which the SUM process currently functions, but instead merely removes the flexibility for the Exchange to allow all TPHs to respond on a class-by-class basis, as this is the manner in which the Exchange intends for the Start Printed Page 47979SUM process to continue to function upon migration.
The Exchange notes that as a result of this proposed change, the proposed rule also removes: (i) The current rule text which provides that an order will not be exposed if the Exchange quotation contains resting orders and does not contain sufficient Market Maker quotation interest to satisfy the entire order; (ii) the early termination provision that terminate an exposure period if Market Maker interest decrements to an amount equal to the size of the exposed order; and (iii) the current Interpretation and Policy .01 which prohibits the redistribution of exposure messages to market participants not eligible to respond to such messages. The proposed rule change removes these provisions because the Exchange proposes for SUM to not be dependent only on Market-Maker interest in any way and all Users will be permitted to respond to all exposure messages.
The proposed rule change also amends the current provision regarding allocation of exposed orders to allow for a User to opt out of having the remaining portion of its exposed order routed to other exchanges following the exposure period.
This is consistent with the EDGX Options SUM rule and the manner in which Users on EDGX Options may currently opt out of having their remaining portion of SUM exposed orders routed away.
The proposed rule change also updates the rule to be consistent with how EDGX Options SUM process handles an All or None (“AON”) order,
which is currently an order type available on the Exchange. Currently (and as proposed), any responses priced at the prevailing NBBO or better, and any unrelated order or quote on the opposite side of the market from the exposed order that could trade against the exposed order at the prevailing NBBO or better, will immediately trade against the exposed order, and the exposure period will continue. A SUM (current HAL) exposure period will currently terminate upon the receipt of a response (or unrelated order or quote) to trade the entire exposed order at the NBBO or better. Because an AON order cannot partially execute pursuant to its terms, the proposed rule change makes it explicit that during the exposure of an AON order, the System will hold responses priced at or better than the prevailing NBBO (rather than trade against the exposed AON immediately) until there is sufficient aggregate size to satisfy the AON order,
and that a SUM exposure period will terminate upon the receipt of multiple responses with sufficient aggregate size to satisfy the AON order.
This is the manner in which the HAL system currently functions, and the proposed change merely codifies this in the proposed rule. In addition to this, the proposed rule change provides that if an AON order is exposed and the Exchange receives an unrelated order or quote that would be displayed at a price at or better than the NBBO with insufficient size to satisfy the exposed order, the SUM exposure period terminates and the exposed order is processed pursuant to the allocation of exposed orders provision 
under the SUM process.
This is consistent with current HAL functionality, to which an order is eligible for the process if its price is marketable against the Exchange's disseminated quotation that is not at the NBBO. Because a SUM auction would not have begun if the Exchange displayed a contra-side order at the NBBO, the Exchange believes it is appropriate to terminate the exposure period if that situation arises in connection with exposed AON orders during the exposure period.
As stated, this is consistent with the way in which the current HAL system and SUM on EDGX Options function.
The Exchange amends the other provisions in connection with early termination of exposure period to be consistent with the EDGX Option's SUM rule. The proposed rule change amends these provisions to include early termination when the exposed order is no longer marketable against the NBBO or if a resting order on the Exchange is locked or crossed by another options exchange.
In addition to aligning with the reasons a SUM auction may currently terminate on EDGX Options, the Exchange believes that these scenarios are reasonable to terminate the SUM process because if an order is no longer marketable, then it cannot be executed through the SUM process and no longer benefit from exposure, and continuing to expose a resting order resting in a locked or crossed market may likely presents difficulties with respect to the handling of the resting order, particularly if an exposed, routable order should be routed for potential price improvement to another options exchange that has published a crossing quotation. The proposed rule change also removes current early termination provisions which would terminate an exposure period when a same-side order is received by the Exchange and if the underlying security enters a limit up limit down state. The Exchange believes because a User will have the ability to cancel its order after the SUM process is initiated coupled with the fact that the Exchange will only execute an order that has been exposed via the SUM process to the extent the order is marketable against the NBBO (as proposed below) will mitigate any potential concern in removing these early termination provisions. As stated, this is consistent with the scenarios for early termination currently on EDGX Options and the Exchange does not believe that the proposed updates present any new or novel changes or significantly impact functionality of the step up process as it will operate in substantially the same manner as it currently does.
The Exchange notes other proposed changes such as making explicit that bulk messages will not be eligible for SUM. Cboe Options intends to implement bulk message functionality upon migration, therefore now proposes to reflect this functionality in its proposed SUM rule (as well as in proposed Rule 5.36 for order routing, described in detail below).
Bulk messages are the equivalent of the Exchange's current quoting functionality. Currently, quotes do not route to other exchanges, and thus are not eligible for HAL. Therefore, the proposed rule change is consistent with current functionality. EDGX Options Rule 21.18 also states that bulk messages are not eligible for SUM. The proposed change also includes a few additional details that are consistent with EDGX Options SUM rule and the manner in which the HAL process currently functions but are not made explicit in the current HAL rule. This Start Printed Page 47980includes making clear that responses are “cancelled back” at the end of the exposure period if unexecuted,
that responses may become executable based on changes to the prevailing NBBO,
and that the Exchange will not initiate the SUM process if the NBBO is crossed.
These updates do not alter the manner in which HAL currently functions but merely make explicit in the rules the operation of the proposed SUM process.
Proposed Rule 5.36
The Exchange proposes to adopt the order routing rule of its affiliated options exchange, C2 Rule 6.15, under proposed Rule 5.36 in the shell Rulebook. The Exchange will continue to support orders that are designated to be routed to the NBBO as well as orders that will execute only within Cboe Options.
Proposed Rule 5.36(a) states for System securities, the order routing process is available to Users from 9:30 a.m. until market close. Users can designate an order as either available or not available for routing. Orders designated as not available for routing and bulk messages, which will not be for routing, are processed pursuant to Rule 5.32 
(which will be the rule governing order and quote Book processing, display, priority, and execution upon migration). For an order designated as available for routing, the System first checks for the Book for available contracts for execution against the order pursuant to Rule 5.32. Unless otherwise instructed by the User, the System then designates the order (or unexecuted portion) as Immediate-or-Cancel (“IOC”) 
and routes it to one or more options exchanges for potential execution, per the User's instructions. After the System receives responses to the order, to the extent it was not executed in full through the routing process, the System processes the order (or unexecuted portion) as follows, depending on parameters set by the User when the incoming order was originally entered:
(i) Cancels the order (or unexecuted portion) back to the User; posts the unfilled balance of the order to the Book, subject to the Price Adjust process described in proposed Rule 5.32(b), if applicable;
(ii) repeats the process described above by executing against the Book and/or routing to the other options exchanges until the original, incoming order is executed in its entirety;
(iii) repeats the process described above by executing against the Book and/or routing to the other options exchanges until the original, incoming order is executed in its entirety, or, if not executed in its entirety and a limit order, posts the unfilled balance of the order on the Book if the order's limit price is reached; or
(iv) to the extent the System is unable to access a Protected Quotation and there are no other accessible Protected Quotations at the NBBO, cancels or rejects the order back to the User, provided, however, that this provision does not apply to Protected Quotations published by an options exchange against which the Exchange has declared self-help.
Currently, the Exchange automatically routes intermarket sweep orders, consistent with the definition in current Rule 6.80(8).
This routing process is functionally equivalent to the current Exchange routing process, and, as proposed, referred to as SWPA and is specifically described in proposed Rule 5.36(a)(2)(B), which is a routing option (and will be the default routing option following migration, and thus, if no other routing option is specified by a User, a User's order subject to routing will be handled in the same way it is today). Following the migration, the Exchange will offer additional routing options identical to the routing options offered by C2 Rule 6.15, as well as by EDGX Options and BZX Options Rule(s) 21.9. Under proposed Rule 5.36(a)(2), routing options may be combined with all available Order Instructions 
and Times-in-Force, with the exception of those whose terms are inconsistent with the terms of a particular routing option. The System considers the quotations only of accessible markets. The term “System routing table” refers to the proprietary process for determining the specific options exchanges to which the System routes orders and the order in which it routes them. The Exchanges reserves the right to maintain a different System routing table for different routing options and to modify the System routing table at any time without notice. These additional routing options are ROUT, destination specific, and directed ISO:
(i) ROUT is a routing option under which the System checks the Book for available contracts to execute against an order and then sends it to destinations on the System routing table. A User may select either Route To Improve (“RTI”) or Route To Fill (“RTF”) for the ROUT routing option. RTI may route to multiple destinations at a single price level simultaneously while RTF may route to multiple destinations and at multiple price levels simultaneously.
(ii) Destination specific is a routing option under which the System checks the Book for available contracts to execute against an order and then sends it to a specific away options exchange.
(iii) Directed ISO is a routing option under which the System does not check the Book for available contracts and sends the order to another options exchange specified by the User. It is the entering User's responsibility, not the Exchanges responsibility, to comply with the requirements relating to Intermarket Sweep Orders.
Proposed Rule 5.36(a)(3) offers two options for Re-Route instructions, Aggressive Re-Route and Super Aggressive Re-Route, either of which can be assigned to routable orders:
(i) Pursuant to the Aggressive Re-Route instruction, if the remaining portion of a routable order has been posted to the Book pursuant proposed subparagraph (a)(1) (i.e., routing away to options exchanges), if the order's price is subsequently crossed by the quote of another accessible options exchange, the System routes the order to the crossing options exchange if the User has selected the Aggressive Re-Route instruction.
(ii) Pursuant to the Super Aggressive Re-Route instruction, to the extent the unfilled balance of a routable order has been posted to the Book pursuant to Start Printed Page 47981subparagraph (a)(1), if the order's price is subsequently locked or crossed by the quote of another accessible options exchange, the System routes the order to the locking or crossing options exchange if the User has selected the Super Aggressive Re-Route instruction.
Proposed Rule 5.36(b) states the System does not rank or maintain in the Book pursuant to Rule 5.32 orders it has routed to other options exchanges, and therefore those orders are not available to execute against incoming orders. Once routed by the System, an order becomes subject to the rules and procedures of the destination options exchange including, but not limited to, order cancellation. If a routed order (or unexecuted portion) is subsequently returned to the Exchange, the order (or unexecuted portion), the order receives a new time stamp reflected the time the System receives the returned order. Proposed Rule 5.36(c) states Users whose orders are routed to other options exchanges must honor trades of those orders executed on other options exchanges to the same extent they would be required to honor trades of those orders if they had executed on the Exchange. These provisions are consistent with the corresponding rules of its affiliated options exchanges, they are substantively identical to the current rule text and functionality of C2 Rule 6.15 and also substantively the same as EDGX Options and BZX Options Rule(s) 21.9.
Proposed Rule 5.36(d) and (f) make explicit certain requirements in connection with Cboe Trading, which, pursuant to current Exchange rules,
is an affiliate of the Exchange that provides inbound and outbound routing services, which currently apply to Cboe Trading today. Proposed Rule 5.36(d) states that the Exchange will route orders in options via Cboe Trading, which currently serves as the Outbound Router of the Exchange. The Outbound Router will route orders in options listed and open for trading on the Exchange to other options exchanges pursuant to Exchange Rules solely on behalf of the Exchange. The Outbound Router is subject to regulation as a facility of the Exchange, including the requirement to file proposed rule changes under Section 19 of the Exchange Act. Use of Cboe Trading or Routing Services (under current Rule 6.14B and proposed Rule 5.36(e)) to route orders to other market centers is optional. Parties that do not desire to use Cboe Trading or other Routing Services provided by the Exchange must designate orders as not available for routing. Proposed Rule 5.35(f) states that in addition to the Rules regarding routing to away options exchanges, Cboe Trading has, pursuant to Rule 15c3-5 under the Exchange Act, implemented certain tests designed to mitigate the financial and regulatory risks associated with providing Trading Permit Holders with access to away options exchanges. Pursuant to the policies and procedures developed by Cboe Trading to comply with Rule 15c3-5, if an order or series of orders are deemed to be erroneous or duplicative, would cause the entering Trading Permit Holder's credit exposure to exceed a preset credit threshold, or are noncompliant with applicable pre-trade regulatory requirements, Cboe Trading will reject the orders prior to routing and/or seek to cancel any orders that have been routed. As stated, these provisions are the same as C2 Rule 6.15(d) and (f) and EDGX Options and BZX Options Rule(s) 21.9(f), and currently apply to Cboe Trading, therefore the proposed change just makes these provisions in connection with Cboe Trading explicit as well as harmonizes its order routing rules with that of its affiliated options exchanges' routing rules.
The proposed rule change moves current Rule 6.14B which governs the routing services provided by non-affiliated routing brokers, to proposed Rule 5.36(e) which is consistent with the corresponding rules of the Exchanges' affiliated options exchanges, C2, EDGX Options, and BZX Options. The Exchange does not proposed any substantive changes to the rule. The Exchange deletes current Interpretation and Policy .01 which states that a routing broker is not prohibited from designating a preferred market-maker at the other exchange to which the order is being routed, which is consistent with the agreements currently in place between the Exchange and its routing brokers, which do not allow for routing broker discretion in connection with order flow. The Exchange also notes that this proposed change is consistent with the corresponding order routing rules of the Exchange's affiliated options exchanges, C2, EDGX Options, and BZX Options.
Finally, the Exchange deletes current Rule 6.6A and current Rule 6.14C because they are duplicative of Exchange Rules and/or routing broker agreements already in place. Current Rule 6.6A provides for the Exchange to cancel or release orders as it deems necessary to maintain fair and orderly markets if a technical or systems issue occurs. These provisions are already covered under other Exchange Rules: Rule 6.6A(a) and (b) are already provided for under current Rule 3.12(a)(6) 
and current Rule 6.14B(f) (proposed Rule 5.36(e)(6)); and Rule 6.6A(c) is already provided for under current Rule 3.12(a)(7)(C). Current Rule 6.14C provides for rules in connection with Routing Service Error Accounts. The provisions in connection with the Exchange's Error Account are currently provided for under Rule 3.12(7), which already requires Cboe Trading, as the Exchange's affiliated outbound router, to maintain an Error Account, provides the Exchange with the authority to assign resulting Error Positions to TPHs or have resulting Error Positions liquidated, and prohibits Cboe Trading from accepting any positions in its error account from an account of a TPH, or permitting any TPH to transfer any positions from the TPH's account to Cboe Trading's error account. The provisions regarding a routing broker's Error Account are already in place in all contracts between the Exchange and its routing brokers pursuant to current Rule 6.14B(a) and (h) (proposed Rule 5.36(e)(1) and (8)). As a result, the proposed rule change deletes current Rules 6.6A and 6.14C as they are duplicative of the current Exchange Rules. The Exchange also notes that this proposed change aligns the Exchange's Rules with that of its affiliated options exchanges, C2, EDGX Options, and BZX Options.
2. Statutory Basis
The Exchange believes the proposed rule change is consistent with the Securities Exchange Act of 1934 (the “Act”) and the rules and regulations thereunder applicable to the Exchange and, in particular, the requirements of Section 6(b) of the Act.
Specifically, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) 
requirements that the rules of an exchange be designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in regulating, clearing, settling, processing information with respect to, and facilitating transactions in securities, to remove impediments to Start Printed Page 47982and perfect the mechanism of a free and open market and a national market system, and, in general, to protect investors and the public interest. Additionally, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) 
requirement that the rules of an exchange not be designed to permit unfair discrimination between customers, issuers, brokers, or dealers.
The proposed rule changes are generally intended to add or align certain system functionality currently offered by the Exchange and the Cboe Affiliated Exchanges in order to provide a consistent technology offering for the Cboe Affiliated Exchanges. A consistent technology offering, in turn, will simplify the technology implementation, changes and maintenance by Users of the Exchange that are also participants on Cboe Affiliated Exchanges. The proposed rule change does not propose to implement new or unique functionality that has not been previously filed with the Commission, found to be consistent with the Act, or is not available on Cboe Affiliated Exchanges. The Exchange notes that the proposed rule text is primarily based on EDGX Options Rules, as well as substantially the same as BZX and C2 Options rules, and is different only to the extent that it makes non-substantive changes to retain some Exchange-specific language/definitions, simplify language and make the rule provisions plain English. The Exchange believes that consistent rules will simplify the regulatory requirements and increase the understanding of the Exchange's operations for Trading Permit Holders that are also participants on the Cboe Affiliated Exchanges. The proposed rule change seeks to provide greater harmonization between the rules of the Cboe Affiliated Exchanges, which would result in greater uniformity and less burdensome and more efficient regulatory compliance. As such, the proposed rule change would foster cooperation and coordination with persons engaged in facilitating transactions in securities and would remove impediments to and perfect the mechanism of a free and open market and a national market system. The Exchange also believes that the proposed amendments will contribute to the protection of investors and the public interest by making the Exchange's rules easier to understand.
The Exchange believes that the proposed rule change to make the current HAL process consistent with the EDGX Options SUM process will serve to remove impediments to and perfect the mechanism of a free and open market and national market system and facilitate transactions in securities because the current HAL process is already equivalent to the EDGX Options SUM process and the proposed rule changes do not raise any new or significant policy concerns, but instead serve to harmonize functionality and the rules across the affiliate exchanges so as to provide market participants with the same product offerings and bolster collective understanding of the rules upon migration.
In addition to protecting and benefitting market participants by providing consistent functionality and rules, the proposed change will continue to allow all Users to submit responses to the exposure message during the exposure period, which the Exchange already does, which will remove impediments to and perfect the mechanism of a free and open national market system in that it will continue to provide all Users with the opportunity to improve their prices and “step up” to meet the NBBO and interact with exposure messages and allow the market participant sending an order to the Exchange to increase its chances of receiving an execution on the preferred venue in which it has chosen to participate (i.e., Cboe Options), thereby benefitting all market participants. In addition to this, the proposed rule change that allows for a User to opt out of having the remaining portion of their exposed order routed to other exchanges following the exposure period will remove impediments to and perfect the mechanism of a free and open national market system by providing Users with additional control regarding the execution of their orders and by providing them with consistent opportunities and functionality across the affiliated exchanges upon migration.
The Exchange also believes the proposed rule change regarding the handling of AON orders exposed in a SUM auction will protect investors because it is identical to the handling of AON orders exposed in the EDGX Options SUM process. Additionally, the proposed rule change will provide AON orders with execution opportunities when the Exchange is not at the NBBO in a manner consistent with the current SUM process and makes it explicit that the exposure period for an AON order will terminate when there is sufficient aggregate contra-side interest to satisfy the exposed AON order (except it will not execute any incoming contra-side interest immediately against the exposed AON order, unless it has sufficient size which will prevent a partial execution in conflict with the AON size contingency), which is the manner in which the current HAL process already functions. This benefits market participants by providing them with rules that accurately reflect current functionality (as well as functionality that will be provided on the Exchange upon migration). The proposed rule change regarding an early termination of the exposure period of an AON order is consistent with current reasons that will cause an exposure period to terminate; it will prevent an exposure period from continuing when new conditions arise that would have prevented an exposure period from initiating in the first place. The proposed rule change will remove impediments to and perfect the mechanism of free and open market and a national market system, because it ensures an AON order will be handled in a manner consistent with the current SUM process.
The proposed rule changes to the other provisions in connection with early termination of exposure period align with the reasons a SUM auction may currently terminate on EDGX Options and will remove impediments to and perfect the mechanism of a free and open market and national market system by terminating an orders that would no longer benefit from exposure or would likely present order handling difficulties, which could impact market participants. In addition to this, because a User will have the ability to cancel its order after the SUM process is initiated coupled with the fact that the Exchange will only execute an order that has been exposed via the SUM process to the extent the order is marketable against the NBBO will mitigate any potential concern in removing other early termination provisions. The Exchange believes that the other updates proposed to align the Exchange's proposed rule with that of the EDGX Options SUM process do not alter the manner in which HAL currently functions but merely make explicit in the rules the operation of the proposed SUM process.
The proposed change to adopt C2's order routing rules (which are also substantially the same as the routing rules on EDGX Options and BZX Options) will likewise serve to protect and benefit market participants by providing consistent functionality and rules in connection with order routing. As stated, the order routing rule of the Exchange's affiliated options exchanges have previously been filed with the Commission. Proposed Rule 5.36 will serve to remove impediments to and perfect the mechanism of a free and open market and national market system because it will allow Users to route orders in much the same way in which Start Printed Page 47983they may already route ISO orders on the Exchange today, and in the same manner as Users may already route orders on the Exchange's affiliated options exchanges, C2, EDGX Options, and BZX Options. Under the proposed rules the System will still process, display and prioritize orders as it currently does as well as ensure the same price protections currently in place, thereby protecting investors. The additional routing options that the proposed rule change offers are the same routing options already available to Users on the Exchange's affiliated options exchange, therefore these options do not raise any new or novel functionality for market participants but ensure that upon migration market participants across the Cboe Affiliated Exchanges will have access to the same functionality and product offerings.
The proposed provisions regarding Cboe Trading will benefit market participants by making explicit certain rules that already apply to Cboe Trading on the Exchange, as well as serve to harmonize the Exchange's routing rules with the corresponding rules of C2 and EDGX Options, as well as BZX Options. The other proposed changes will also remove impediments to and perfect the mechanism of a free and open national market system by removing rules that are duplicative of other Exchange rules that currently provide for the same and are already effectively provided for in the contracts between the Exchange and its non-affiliated routing brokers. This, in turn, provides market participants with up-to-date, streamlined rules with are easy to understand, and mirror the corresponding rules of C2 and EDGX Options, as well as BZX Options.
The proposed rule change makes other various non-substantive changes throughout the rules that will protect investors and benefit market participants as these changes simplify the rules and use plain English throughout the rules.
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 reiterates that the proposed rule change is being proposed in the context of a technology migration of the Cboe Affiliated Exchanges. As stated, the proposed changes to the rules that reflect functionality that will be in place come October 7, 2019 provide clear, consistent rules for market participants upon the completion of migration. The Exchange believes the proposed rule change will benefit Exchange participants in that it will provide a consistent technology offering for Users by the Cboe Affiliated Exchanges.
The Exchange does not believe the proposed rule change will impose any burden on intramarket competition. The proposed SUM process and order routing functionality will apply to all Users and order and quotes submitted by Users in the same manner. Like HAL currently, the Exchange's proposed SUM is open to all Users. Additionally, all Users will have the option to route orders to away exchanges, and apply the different proposed routing instructions, under the proposed order routing provisions.
The Exchange does not believe that the proposed rules change will impose any burden on intermarket competitions. As discussed above, the basis for the proposed rule changes in this filing are the rules of C2 and EDGX Options, as well as substantial similarities to the approved rules of BZX Options, which have already been filed with the Commission. The Exchange also notes that market participants on other exchanges are welcome to become participants on the Exchange if they determine that this proposed rule change has made Cboe Options a more attractive or favorable venue.
C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others
The Exchange neither solicited nor received comments on the proposed rule change.
III. Date of Effectiveness of the Proposed Rule Change and Timing for Commission Action
Because the foregoing proposed rule change does not:
