SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-103184; File No. SR-CBOE-2025-038]


Self-Regulatory Organizations; Cboe Exchange, Inc.; Notice of 
Filing and Immediate Effectiveness of a Proposed Rule Change To Amend 
Its Opening Process for Simple Orders in Exclusively Listed Index 
Option Classes

June 4, 2025.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(the ``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given 
that on May 22, 2025, 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 and II 
below, which Items have been prepared by the Exchange. 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

    Cboe Exchange, Inc. (the ``Exchange'' or ``Cboe Options'') proposes 
to amend its opening process for simple orders in exclusively listed 
index option classes.\3\ The text of the proposed rule change is 
provided in Exhibit 5.
---------------------------------------------------------------------------

    \3\ An ``exclusively listed option'' is an option that may trade 
exclusively on an exchange (and its affiliated exchange) because the 
exchange has an exclusive license to list and trade the option or 
has the proprietary rights in the interest underlying the option. An 
exclusively listed option is different than a ``singly listed 
option,'' which is an option that is not an ``exclusively listed 
option'' but that is listed by one exchange and not by any other 
national securities exchange.
---------------------------------------------------------------------------

    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 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The Exchange proposes to amend Rule 5.31 regarding its opening 
process for simple orders for products it may exclusively list on the 
Exchange (except for SPX constituent option series on exercise 
settlement value determination dates \4\).
---------------------------------------------------------------------------

    \4\ See Rule 5.31(j).
---------------------------------------------------------------------------

Current Standard Opening Process
    Currently, following the occurrence of an opening rotation trigger 
pursuant to Rule 5.31(d), the System conducts an opening rotation for 
an option series. Following the opening rotation trigger, the System 
conducts the Maximum Composite Width Check pursuant to Rule 5.31(e)(1) 
to determine if a series is eligible to open. If the Composite Market 
\5\ of a series is not crossed, and the Composite Width \6\ of the 
series is less than or equal to the Maximum Composite Width (as defined 
in Rule 5.31(a)), the series is eligible to open. Additionally, if the 
Composite Market of a series is not crossed, and the Composite Width of 
the series is greater than the Maximum Composite Width, but there are 
(i) no non-M Capacity \7\ (a) market orders or (b) buy (sell) limit 
orders with prices higher (lower) than the Composite Market midpoint 
and (ii) no orders or quotes marketable against each other, the series 
is eligible to open. Once a series become eligible to open, the System 
conducts the opening auction for the series (i.e. determines the 
opening trade price pursuant to Rule 5.31(e)(2) and opens the series 
pursuant to Rule 5.31(e)(3)). The Exchange may also determine to compel 
a series to open in the interest of fair and orderly markets, including 
if the opening width

[[Page 24472]]

is wider than the Maximum Composite Width, pursuant to Rule 5.31(h).
---------------------------------------------------------------------------

    \5\ The term ``Composite Market'' means the market for a series 
comprised of (1) the higher of the then-current best appointed 
Market-Maker bulk message bid on the Exchange and the away best bid 
(``ABB'') (if there is an ABB) and (2) the lower of the then-current 
best appointed Market-Maker bulk message offer on the Exchange and 
the away best offer (``ABO'') (if there is an ABO). The term 
``Composite Bid (Offer)'' means the bid (offer) used to determine 
the Composite Market. See Rule 5.31(a).
    \6\ The term ``Composite Width'' means the width of the 
Composite Market (i.e., the width between the Composite Bid and the 
Composite Offer) of a series. See Rule 5.31(a).
    \7\ A non-M Capacity order is a non-Market Maker order. See Rule 
1.1, definition of Capacity for a list of other Capacities that may 
be attached to an order.
---------------------------------------------------------------------------

    Currently, if a series cannot satisfy these conditions described 
above (and thus is not eligible to open), if there is no Composite 
Market, or if the Composite Market of a series is crossed, the series 
is ineligible to open.\8\ When that occurs, the Queuing Period \9\ for 
the series continues (including the dissemination of opening auction 
updates) until (i) the Maximum Composite Width Check is satisfied and 
the Composite Market is not crossed; (ii) there are (a) no non-M 
Capacity (x) market orders or (y) buy (sell) limit orders with prices 
higher (lower) than the Composite Market midpoint and (b) no orders or 
quotes marketable against each other if the Maximum Composite Width is 
not satisfied and the Composite Market is not crossed, or (iii) the 
Exchange determines to open the series pursuant to Rule 5.31(h). As 
described further herein, the Exchange may now manually increase the 
prescribed Maximum Composite Width during the Queuing Period in order 
to open up an exclusively listed option series.\10\
---------------------------------------------------------------------------

    \8\ See Rule 5.31(e)(1)(C).
    \9\ The term ``Queuing Period'' means the time period prior to 
the initiation of an opening rotation during which the System 
accepts orders and quotes in the Queuing Book (the book into which 
Users may submit orders for participation in the opening rotation) 
for participation in the opening rotation for the applicable trading 
session. See Rule 5.31(a).
    \10\ See the definition of Maximum Composite Width, which 
permits the Exchange to modify the Maximum Composite Width during 
the opening auction process (which modifications the Exchange 
disseminates to all subscribers via the Exchange's data feeds that 
deliver opening auction updates) in Rule 5.31(a).
---------------------------------------------------------------------------

Current Forced Opening Procedures for Equity and ETP Options Classes
    However, currently, if a series in an equity or ETP option class is 
unable to open because it does not satisfy the Maximum Composite Width 
Check within an Exchange-designated time period (and (i) the Composite 
Market is not crossed and (ii) no non-M Capacity order crosses the 
Composite Market midpoint) \11\, the System forces the series to open 
after that time period upon the System's observation of an ABBO \12\ 
(with a non-zero offer) for the series.\13\
---------------------------------------------------------------------------

    \11\ The Exchange proposes to modify the existing forced open 
rule for equity and ETP option classes to clarify that it will not 
force the open if there are non-M Capacity orders that cross the 
Composite Market midpoint. While the Exchange currently follows this 
process, it proposes to make this clear in its rule as well.
    \12\ The term ``ABBO'' means the best bid(s) or offer(s) 
disseminated by other Eligible Exchanges (as defined in Rule 5.65) 
and calculated by the Exchange based on market information the 
Exchange receives from OPRA. See Rule 1.1.
    \13\ See Rule 5.31(e)(4).
---------------------------------------------------------------------------

Background on the Current Opening Procedures for Exclusively Listed 
Options
    As mentioned above, and as described further herein, the Exchange 
may now manually force open a series that does not satisfy the Maximum 
Composite Width by increasing the prescribed Maximum Composite Width 
during the Queuing Period in order to open up a series.\14\ The 
Exchange currently exercises more discretion through this manual 
process then it would through the proposed automated process as it must 
manually review which series are not open and can determine whether it 
wants to force the series open. In neither the existing process nor in 
the proposed automated process through the proposed modified forced 
open rule is there are an ABBO looked to (as it does not exist).
---------------------------------------------------------------------------

    \14\ See the definition of Maximum Composite Width, which 
permits the Exchange to modify the Maximum Composite Width during 
the opening auction process (which modifications the Exchange 
disseminates to all subscribers via the Exchange's data feeds that 
deliver opening auction updates) in Rule 5.31(a).
---------------------------------------------------------------------------

    However, under the existing manual process to increase the Maximum 
Composite Width, if there are no Market Maker orders, and thus no 
Composite Width for the Exchange to manually increase, a series will 
not open, unless the Exchange deems it necessary for fair and orderly 
markets and opens a series pursuant to Rule 5.31(h). The new rule 
proposes that a forced open shall occur if there is no Composite Market 
so long as there are no non-M Capacity orders that are crossed. As 
described in further detail below, the Exchange believes this is in the 
best interest of market participants, as the exclusively listed options 
generally have a strong floor presence in addition to the on-screen 
liquidity--it may be the case that while there is no Composite Market 
on screen, there are Market Makers on the floor that can fill the 
customer orders. Of further note, it is also the case for some Market 
Makers that they may not provide on-screen liquidity until after they 
receive the opening trigger notification. For these reasons, the 
Exchange believes it is in the best interest to open up these series 
even if no Composite Market exists and no non-M Capacity orders are 
crossed.
    The Exchange also notes that it may use Rule 5.31(h) to deviate 
from the standard opening process, including: (i) adjusting the timing 
of the opening rotation in any option class, (ii) modifying any time 
periods described in Rule 5.31, and (iii) compelling a series open, 
even if the Maximum Composite Width check is not satisfied, but these 
events may only happen manually if the Exchange determines it is 
necessary in the interests of a fair and orderly market. The Exchange 
notes that it will retain this authority still under the new proposed 
forced opening rule.
Proposed Forced Opening Procedures for Exclusively Listed Options
    The proposed rule change expands the existing forced opening 
provision to now apply to exclusively listed option series, except that 
(i) the ABBO will not be used as a triggering factor to open a series 
as there is no ABBO for the exclusively listed option series and (ii) 
the series may open if there is no Composite Market so long as there 
are no non-M Capacity orders that are crossed.\15\ Similar to equity or 
ETP option classes, the series will not open if the Composite Market is 
crossed or if there are non-M Capacity orders that cross the Composite 
Market midpoint.
---------------------------------------------------------------------------

    \15\ The proposed forced opening process has no impact on the 
modified opening auction process set forth in Rule 5.31(j) and would 
not apply to SPX constituent option series on exercise settlement 
value determination days.
---------------------------------------------------------------------------

    Specifically, as proposed, if a series in an exclusively listed 
option class is unable to open because it does not satisfy the Maximum 
Composite Width Check described above within a time period (which the 
Exchange determines for exclusively listed options \16\) after the 
occurrence of the opening rotation trigger for the class pursuant to 
Rule 5.31(d), and (i) the Composite Market is not crossed and no non-M 
Capacity order crosses the Composite Market midpoint or (ii) there is 
no Composite Market and there are no non-M Capacity orders that are 
crossed, the System forces the series to open after that time period. 
For a series subject to a forced opening, the opening trade price 
determination and series open set forth in Rule 5.31(e)(2) and (3) 
(i.e., the opening auction) do not occur; instead, the System opens the 
series without a

[[Page 24473]]

trade. This will permit a series to open for trading on the Exchange 
even though the market for the series on the Exchange may be wide (or 
if there are no quotes or orders on the book).\17\ As described above, 
the two primary distinctions between the existing manual process that 
is used to manually open exclusively listed options, where the Maximum 
Composite Width is manually widened, and the proposed forced opening 
process for exclusively listed options, are (i) the proposed automated 
process is more efficient and transparent process and (ii) an 
exclusively listed option series may still open even if there is no 
Composite Market so long as no non-M Capacity orders are crossed. 
However, as previously noted, the Exchange may also open up a series if 
it deems so necessary in the interest of a fair and orderly market 
pursuant to Rule 5.31(h).
---------------------------------------------------------------------------

    \16\ The proposed rule change permits the Exchange to determine 
one time period for all exclusively listed options and one time 
period for equity and ETP classes, which may be the same time 
period. The Exchange believes in doing so, it can best adapt to 
unique changes with its exclusively listed options to account for 
the fact that its exclusively listed options are also traded during 
GTH session and, in addition to being traded electronically (as the 
equity and ETP classes are), they are also traded open outcry as 
well.
    \17\ The Exchange notes that a wide market is not a reason 
enough for not opening as a wide market may occur at any point 
during the trading day. As described further herein, it is more of a 
risk for participants to keep the market closed, preventing 
participants from managing their position exposure as other markets 
are already open.
---------------------------------------------------------------------------

    If a series satisfies the Maximum Composite Width Check prior to 
the end of the Exchange-determined time period, the series opens 
pursuant to Rule 5.31(d)(2) and (3) (i.e., the standard opening auction 
process occurs for the series). For example, suppose the Exchange 
determined the ``forced opening'' timer for exclusively listed option 
series to be three minutes. If the opening trigger for an exclusively 
listed option series occurs at 9:30:05 Eastern time but the series does 
not satisfy the Maximum Composite Width Check after the trigger, the 
System will force the series open after 9:33:05 Eastern time. However, 
if the series satisfies the Maximum Composite Width Check at 9:32:30, 
the series will open at that time in accordance with the normal opening 
auction process. The current rule still allows the market to open even 
if the market is wide by (i) manually increasing the Maximum Composite 
Width \18\ or (ii) allowing the series to open in accordance with Rule 
5.31(e)(1)(B), which allows the series to open if the Composite Market 
of a series is not crossed, and the Composite Width of the series is 
greater than the Maximum Composite Width, but there are (i) no non-M 
Capacity (a) market orders or (b) buy (sell) limit orders with prices 
higher (lower) than the Composite Market midpoint and (ii) no orders or 
quotes marketable against each other.
---------------------------------------------------------------------------

    \18\ See supra note 16.
---------------------------------------------------------------------------

No ABBO Requirement for Exclusively Listed Options
    Given the current method of manually increasing the Maximum 
Composite Width as a way to force a series open if it does not satisfy 
the Maximum Composite Width, the Exchange believes the proposed rule is 
a better alternative to open up a series for trading, as it allows for 
greater transparency and clearer expectations for market participants, 
as well as taking away the possibility of error from manual human 
intervention. As described further herein, the ABBO is not a 
requirement for the standard opening process for any option classes, 
including equity and ETP option classes. Specifically, if no away 
markets are open in a series, there would be no ABBO for that series 
and thus the Composite Market for the series (and thus whether the 
series would open) would be based solely on the Exchange's market for 
the series. Further, if the ABBO is wider than the Exchange's market 
for a series, the ABBO is also not a factor into whether the System 
opened the series. In those cases, whether an equity or ETF option 
series satisfied the Maximum Composite Width check would be based 
solely on the Exchange's market. With respect to the forced opening 
process for equity and ETP option classes, it may even be the case that 
the ABBO is wider than the Exchange's market.
Differences Between the Forced Opening Process for Equity and ETP 
Option Classes and the Proposed Process for Exclusively Listed Options
    The Exchange notes that it previously adopted a similar process to 
force an open for series in an equity or exchange-traded product option 
classes.\19\ The only substantive differences within these two 
processes is that (i) the process for exclusively listed options will 
not rely on the additional requirement that the system observes an ABBO 
after the designated time period passes since exclusively listed 
options will not have an ABBO as the products are not listed on any 
other exchange and (ii) exclusively listed option series may open if 
there is no Composite Market so long as there are no non-M Capacity 
orders that are crossing.
---------------------------------------------------------------------------

    \19\ See Securities Exchange Act Release No. 90967 (January 22, 
2021), 86 FR 7429 (January 28, 2021) (SR-CBOE-2021-005).
---------------------------------------------------------------------------

    With the exception that there is not an ABBO that may be looked at 
first and that a Composite Market is not required to exist (so long as 
there are no non-M Capacity orders that are crossed), all other 
protections that were put into place during the inception of the forced 
open for equity and ETP classes will also apply to the proposed forced 
open for exclusively listed options. Rule 5.31(f) provides that in the 
event of a forced opening of a series pursuant to proposed Rule 
5.31(e)(4) or a compelled opening of a series pursuant to paragraph 
(h), the System enters all of a User's orders in that series in the 
Queuing Book \20\ into the Book in the manner set forth in current Rule 
5.31(f), unless a User instructs the System to cancel its market orders 
or all of its orders, in which case the System enters only the non-
cancelled orders into the Book in this manner. Specifically, they will 
be processed in accordance with Rule 5.32 (as unexecuted orders and 
quotes are handled following the conclusion of the opening rotation), 
which describes how the System processes, handles, and executes orders. 
If any order or quote in the Queuing Book is marketable upon the forced 
opening (and the User does not instruct the System to cancel it as 
proposed), the System would execute marketable orders subject to the 
priority rules set forth in Rule 5.32. Any non-marketable order would 
enter the Book or cancel, subject to the User instructions. This 
proposed change provides Users with flexibility for automated handling 
of their orders in the event an exclusively listed option series opens 
with a wide market as opposed to the existing manual process where the 
Exchange manually increases the Maximum Composite Width to force an 
open.\21\
---------------------------------------------------------------------------

    \20\ The term ``Queuing Book'' means the book into which Users 
may submit orders and quotes (and onto which GTC and GTD orders 
remaining on the Book from the previous trading session or trading 
day, as applicable, are entered) during the Queuing Period for 
participation in the applicable opening rotation. Orders and quotes 
on the Queuing Book may not execute until the opening rotation. The 
Queuing Book for the GTH opening auction process may be referred to 
as the ``GTH Queuing Book,'' and the Queuing Book for the RTH 
opening auction process may be referred to as the ``RTH Queuing 
Book. See Rule 5.31(a).
    \21\ See supra note 16.
---------------------------------------------------------------------------

SPX Constituent Option Series
    Lastly, the Exchange proposes to amend Rule 5.31(e)(4) to not apply 
the proposed forced opening process to the opening of the SPX 
constituent option series on exercise settlement value determination 
dates, as the opening auction process currently set forth in Rule 
5.31(j) to calculate the exercise or

[[Page 24474]]

final settlement, as applicable, of expiring VIX derivatives shall 
still apply to those series on those dates. Therefore, SPX constituent 
option series will open pursuant to Rule 5.31(j) on exercise settlement 
value determination dates.
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.\22\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \23\ 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 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. Additionally, 
the Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \24\ requirement that the rules of an exchange not be 
designed to permit unfair discrimination between customers, issuers, 
brokers, or dealers.
---------------------------------------------------------------------------

    \22\ 15 U.S.C. 78f(b).
    \23\ 15 U.S.C. 78f(b)(5).
    \24\ Id.
---------------------------------------------------------------------------

    In particular, the Exchange believes the proposed forced opening 
process for simple orders in its exclusively listed option series will 
remove impediments to and perfect the mechanism of a free and open 
market and a national market system and protect investors. The proposed 
rule change will provide for a series to open for trading on the 
Exchange sooner than it may automatically open currently. The Exchange 
believes the proposed rule change will benefit investors, because it 
may permit these options to open sooner and increase the times during 
which investors may conduct trading in these options, allowing 
participants to trade, hedge exposure, and exit positions in a timely 
manner. While the width of Market-Maker quotes on the Exchange (and 
thus the Composite Width) for an exclusively listed option series may 
be wider than the Maximum Composite Width \25\ or, no Market-Maker 
quotes for an exclusively listed option series are present in the book 
(and thus there is no Composite Market for the series), the Exchange 
believes it is reasonable to open the series after a certain amount of 
time has passed. The Exchange further notes that it does not believe 
wide Market Maker quotes in and of itself is an adequate reason to 
delay the opening, as that may occur at any time during the trading 
day. The Exchange understands from customers they would prefer to be 
able to begin trading the Exchange's exclusively listed index options 
without undue delay, even in a wide market, in a timeframe more closely 
aligned with equities and ETP options \26\ (there have been delays as 
long as ten to fifteen minutes after markets open). A delayed opening 
may leave participants unable to efficiently hedge, exit, and otherwise 
manage positions as needed, particularly because the value of the index 
may be changing given that the stocks comprising the index are open for 
trading. As a result, a delayed opening may create more investment risk 
for market participants than opening with a market comprised of wide or 
no Market-Maker quotes (which as noted above, is a market condition 
that may occur at any time). Additionally, the proposed ability of 
Users to cancel orders in the event of a forced opening will provide 
Users with additional protection.
---------------------------------------------------------------------------

    \25\ The Exchange notes pursuant to Rule 5.31(e)(1)(B), there 
are currently instances in which the Exchange will open for trading 
despite the Composite Market Width being larger than the Maximum 
Composite Width.
    \26\ See Rule 5.31(e)(4).
---------------------------------------------------------------------------

    As discussed above, the Exchange currently has the authority, when 
it deems necessary, to deviate from the standard opening process, 
including: (i) adjusting the timing of the opening rotation in any 
option class, (ii) modifying any time periods described in Rule 5.31, 
and (iii) compelling a series open, even if the Maximum Composite Width 
check is not satisfied, but these events may only happen manually if 
the Exchange determines it is necessary in the interests of a fair and 
orderly market.\27\ The proposed rule change is consistent with the 
authority granted under Rule 5.31(h). Furthermore, this proposed rule 
change creates an automated compelled opening in certain circumstances 
by not needing to rely on the manual process of increasing the Maximum 
Composite Width that may currently be used under the definition of 
Maximum Composite Width under Rule 5.31(a), with the exception that a 
series may be forced open under this proposed rule even if no Composite 
Market exists, so long as there are no non-M Capacity orders crossed. 
This will benefit investors by providing additional transparency to the 
Rules regarding when a series may open despite not satisfying the 
Maximum Composite Width check as well as remove impediments to and 
perfect the mechanism of a free and open market and a national market 
system by automating an otherwise manual process. Furthermore, the 
Exchange believes it is in the best interest of investors to allow an 
exclusively listed option series to open even if there is no Composite 
Market, so long as no non-M Capacity orders are crossed, as there may 
be liquidity on the floor from Market Makers. This continues to protect 
customer orders from executing at the open at a potentially erroneous 
price given that the requirement that there be no non-M Capacity orders 
crossed. By allowing these markets to open in a timely manner, market 
participants would be able to have their orders filled and manage their 
existing positions earlier, thus reducing potential investment risk 
associated with further delaying the open.
---------------------------------------------------------------------------

    \27\ See Rule 5.31(h).
---------------------------------------------------------------------------

    Further, as discussed above, the Exchange believes it is in the 
best interest of market participants to allow the Exchange discretion 
to determine a different time period for its exclusively listed options 
that may be different from the time period for its equity and ETP 
options. As noted, there are differences that between these groups, 
notably, that exclusively listed options also trade in an open outcry 
market in addition to trading electronically (equity and ETP options 
are only traded electronically on the Exchange) and exclusively listed 
options may also trade during the GTH trading session. Further, under 
Rule 5.31(h), the Exchange already has the authority to adjust any time 
periods under Rule 5.31, which include the forced open timers, when it 
deems necessary for a fair and orderly market. The Exchange proposes to 
make this discretion clear within the proposed rule, where the Exchange 
may have different timers for (i) equity and ETP options and (ii) 
exclusively listed options.
    Additionally, by establishing this process instead of manually 
increasing the Maximum Composite Width, the Exchange believes this 
provides greater transparency and clarity and better sets out 
expectations for participants. The Exchange notes that it still 
maintains its existing authority under Rule 5.31(h) to deviate from the 
standard manner of the opening auction process. The Exchange does not 
think that not having an ABBO (as none exists for exclusively listed 
options) is of note, as the Exchange manually forces an open now by 
increasing the Maximum Composite Width and an ABBO is not required

[[Page 24475]]

under that procedure. Of further note, the ABBO is not a requirement 
for the standard opening process for any option classes, including 
equity and ETP option classes. Specifically, if no away markets are 
open inequity or ETP options, there would be no ABBO for that series 
and thus the Composite Market for the series (and thus whether the 
series would open) would be based solely on the Exchange's market for 
the series. Further, if the ABBO is wider than the Exchange's market 
for a series, the ABBO is also not a factor into whether the System 
opened the series. In those cases, whether an equity or ETF option 
series satisfied the Maximum Composite Width check would be based 
solely on the Exchange's market.
    Further, as previously discussed, the Exchange believes it furthers 
its goal of conducting fair and orderly markets by forcing its 
exclusively listed options to open if there is no Composite Market. In 
the event there is no Composite Market from there being no on-screen 
two-sided market from Market Maker bids and offers, and there are no 
non-M Capacity orders that are crossed, the Exchange believes it is in 
the benefit of the market to move forward with opening, so customers 
may commence trading. As described above, there may be liquidity on the 
floor from Market Makers and the Exchange understands from market 
participants they would rather commence trading to manage their 
positions even if there are wide, or no, Market-Maker quotes on the 
book.

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 does not 
believe that the proposed rule change will impose any burden on 
intramarket competition that is not necessary or appropriate in 
furtherance of the purposes of the Act because all Users may trade in 
any exclusively listed option series that opens subject to the proposed 
forced opening process. The proposed forced opening process for 
exclusively listed option series is also substantially similar to the 
current forced opening process for equity and ETP option series, with 
the exception that, (i) there is no ABBO for exclusively listed option 
series, and thus, is not a step in the forced opening process for the 
exclusively listed option series and (ii) a Composite Market is not 
required for exclusively options, as described above. Additionally, all 
Users will have the opportunity to instruct the System to cancel its 
market orders or all open orders in the event of a forced or otherwise 
manual opening. Cancellation of some or all of a User's orders in the 
event of such an opening would be voluntary and completely within the 
User's discretion.
    The Exchange does not believe that the proposed rule change will 
impose any burden on intermarket competition that is not necessary or 
appropriate in furtherance of the purposes of the Act because the 
proposed rule change updates the opening process for exclusively listed 
options that may trade only on the Exchange. As discussed above, the 
proposed rule change will allow participants to begin trading, hedging 
exposure, and exiting positions in exclusively listed options in a 
timely manner, consistent with the timing and process the Exchange 
currently uses for equity and ETP options. The proposed flexibility for 
Users to instruct the System how to handle their orders in the event of 
a forced or manual opening applies only to how a User's orders on the 
Exchange will be handled in such a circumstance.

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:
    A. significantly affect the protection of investors or the public 
interest;
    B. impose any significant burden on competition; and
    C. become operative for 30 days from the date on which it was 
filed, or such shorter time as the Commission may designate, it has 
become effective pursuant to Section 19(b)(3)(A) of the Act \28\ and 
Rule 19b-4(f)(6) \29\ thereunder.\30\
---------------------------------------------------------------------------

    \28\ 15 U.S.C. 78s(b)(3)(A).
    \29\ 17 CFR 240.19b-4(f)(6).
    \30\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6) 
requires a self-regulatory organization to give the Commission 
written notice of its intent to file the proposed rule change at 
least five business days prior to the date of filing of the proposed 
rule change, or such shorter time as designated by the Commission. 
The Exchange has satisfied this requirement.
---------------------------------------------------------------------------

    At any time within 60 days of the filing of the proposed rule 
change, the Commission summarily may temporarily suspend such rule 
change if it appears to the Commission that such action is necessary or 
appropriate in the public interest, for the protection of investors, or 
otherwise in furtherance of the purposes of the Act. If the Commission 
takes such action, the Commission will institute proceedings to 
determine whether the proposed rule change should be approved or 
disapproved.
