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 codify that certain disruptive order and quote entry and trading 
activity is prohibited by Exchange Rules as being inconsistent with 
just and equitable principles of trade. The text of the proposed rule 
change is provided in Exhibit 5.
    The text of the proposed rule change is also available on the 
Commission's website (<a href="https://www.sec.gov/rules/sro.shtml">https://www.sec.gov/rules/sro.shtml</a>), the 
Exchange's website (<a href="https://www.cboe.com/us/options/regulation/rule_filings/bzx/">https://www.cboe.com/us/options/regulation/rule_filings/bzx/</a>), and at the principal office of the Exchange.

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 adopt Rule 8.23, which would codify that 
disruptive order and quote entry and trading activity are prohibited by 
the Exchange's Rules and the Securities Exchange Act of 1934, as 
amended (the ``Act''), and the rules and regulations thereunder. As a 
national securities exchange registered pursuant to Section 6 of the 
Act, the Exchange is required to be organized and to have the capacity 
to enforce compliance by its members and persons associated with its 
members, with the Act, the rules and regulations thereunder, and the 
Exchange's Rules.\3\ Further, the Exchange's Rules are required to be 
``designed to prevent fraudulent and manipulative acts and practices, 
to promote just and equitable principles of trade . . . and, in 
general, to protect investors and the public interest.'' \4\ In 
fulfilling these requirements, the Exchange has developed a 
comprehensive regulatory program that includes automated surveillance 
of trading activity. When the Exchange identifies or becomes aware of 
disruptive and potentially manipulative or improper order or quote 
entry or trading activity, the Exchange investigates the activity and 
may determine to commence a disciplinary action against the Trading 
Permit Holder(s) involved pursuant to Chapter XIII of the Rules.
---------------------------------------------------------------------------

    \3\ 15 U.S.C. 73f(b)(1).
    \4\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    Various Rules currently prohibit disruptive order and quote entry 
and trading activity, including:
    <bullet> Rule 8.1, which prohibits TPHs from engaging in acts or 
practices inconsistent with just and equitable principles of trades;
    <bullet> Rule 8.2, which prohibits TPHs from engaging in conduct in 
violation of the Act, the rules and regulations thereunder, and 
Exchange Rules;
    <bullet> Rule 8.6, which prohibits TPHs from engaging in market 
manipulation, including effecting or inducing the purchase, sale, or 
exercise of any security for the purpose of creating or inducting a 
false, misleading, or artificial appearance of activity in such 
security or in the underlying security, or for the purpose of unduly or 
improperly influencing the market price of such security or of the 
underlying security or for the purpose of making a price that does not 
reflect the true state of the market in such security or in the 
underlying security;
    <bullet> Rule 8.10, which prohibits TPHs from misusing material, 
nonpublic information;
    <bullet> 5.32 and 5.85, which include provisions regarding the 
priority of order and quote bids and offers of all TPHs; and
    <bullet> 5.9, which imposes order exposure requirements on TPHs.
    Further Section 9(a)(1) of the Act provides in relevant part that 
it shall be unlawful for any member of a national securities exchange, 
for the purpose of creating a false or misleading appearance of active 
trading in any security other than a government security, or a false or 
misleading appearance with respect to the market for any such security, 
(A) to effect any transaction in such security which involves no change 
in the beneficial ownership thereof, or (B) to enter an order or orders 
for the purchase of such security with the knowledge that an order or 
orders of substantially the same size, at substantially the same time, 
and at substantially the same price, for the sale of any such security, 
has been or will be entered by or for the same or different parties, or 
(C) to enter any order or orders for the sale of any such security with 
the knowledge that an order or orders of substantially the same size, 
at substantially the same time, and at substantially the same price, 
for the purchase of such security, has been or will be entered by or 
for the same or different parties.\5\ Finally, among other things, the 
activity could also result in a violation of Rule 10b-5 under the Act 
(which prohibits any act, practice, or course of business which 
operates or would operate as a fraud or deceit upon any person, in 
connection with the purchase or sale of any security).\6\

---------------------------------------------------------------------------

    Ultimately, TPHs (on their own behalf or on behalf of customers) 
should be submitting all orders and quotes at any time for the purpose 
of executing bona fide transactions or in good faith for legitimate 
purposes. The Exchange has identified various activities that may 
comprise disruptive order and quote entry or trading activity in 
violation of its Rules. As order or quote entry or trading activity not 
done for the purpose of executing bona fide transactions or is done for 
illegitimate purposes, and thus prohibited by the Act or Exchange Rules 
(as set forth above), can take many forms, the Exchange has issued 
guidance through Regulatory Circulars to identify examples of when such 
behavior is disruptive and thus prohibited by the Act or Exchange Rules 
(as set forth above).\7\ While it is the case that various Rules and 
the Act currently prohibit disruptive order and quote entry and trading 
activity, and other manipulative trading activity, the Exchange 
proposes to define more specifically and to codify in its Rules

[[Page 4647]]

what constitutes prohibited activity.\8\ The Exchange believes it would 
be beneficial to describe and specify in the Rules what constitutes 
prohibited order and quote entry and trading activity to provide TPHs 
with additional context for situations in which the Exchange may take 
disciplinary action against them for certain activity as being for 
illegitimate and non-bona fide purposes. The Exchange believes this may 
help TPHs avoid in engaging in such activities or allowing their 
clients to engage in such activities, which may thus reduce 
manipulative and disruptive activity on the Exchange.
---------------------------------------------------------------------------

    \7\ See, e.g., Cboe Regulatory Circular 22-014 (September 26, 
2022), available at RC22-014 Prearranged Trading and Signaling of 
Imminent Orders (<a href="http://cboe.com">cboe.com</a>); and Cboe Regulatory Circular 22-008 
(March 18, 2022), available at RC22-008 Quote and Order Messaging--
Prohibited Activity (<a href="http://cboe.com">cboe.com</a>). Other exchanges have similarly 
issued notices to their members to specify certain behavior that is 
deemed to be considered violations of those exchanges' rules that 
(like Exchange Rule 8.1) prohibit acts or practices inconsistent 
with just and equitable principles of trading. See, e.g., MIAX 
Options Exchange Regulatory Circular 2022-09, MIAX Pearl Options 
Exchange Regulatory Circular 2022-09, MIAX Emerald Options Exchange 
Regulatory Circular 2022-09, available at 
MIAX_Options_RC_2022_09.pdf (<a href="http://miaxglobal.com">miaxglobal.com</a>); and BOX Exchange 
Regulatory Circular RC-2022-004 (March 10, 2022), available at RC-
2022-04-Invalid-and-Incomplete-Message-Transmissions.pdf 
(<a href="http://boxoptions.com">boxoptions.com</a>).
    \8\ The Exchange notes this list is not exhaustive, as activity 
not specified may still be deemed disruptive and thus prohibited by 
the Act or Exchange Rules, including those set forth above.
---------------------------------------------------------------------------

    Specifically, proposed Rule 8.23(a) states that TPHs, on their own 
behalf or on behalf of customers, must submit all orders and quotes at 
any time for the purpose of executing bona fide transactions or in good 
faith for legitimate purposes. Non-bona fide or nonlegitimate purposes 
include, but are not limited to:

    (1) entering an order or quote with the intent, at the time of 
entry, to cancel the order or quote before execution or to modify 
the order or quote to avoid execution;
    (2) entering or causing to be entered an actionable or 
nonactionable message(s) with intent to mislead other market 
participants;
    (3) entering into a transaction or series of transactions, 
coupled with an agreement, arrangement, or understanding, directly 
or indirectly to reverse such transaction(s), which is not done for 
a legitimate economic purpose or is done without subjecting the 
transaction to market risk;
    (4) entering orders or quotes to signal the arrival of an order 
or otherwise to coordinate order flow with another market 
participant;
    (5) entering or using IOC orders or quotes for purposes other 
than to remove resting interest in the Book or the excessive use of 
IOC orders or quotes;
    (6) entering or causing to be entered an actionable or 
nonactionable message(s) with intent to overload or delay the 
systems of the Exchange or other market participants, including 
dividing an order or quote into multiple messages;
    (7) intentionally or recklessly submitting or causing to be 
submitted an actionable or nonactionable message(s) that has the 
potential to disrupt the systems of the Exchange or other market 
participants;
    (8) entering or causing to be entered an actionable or 
nonactionable message(s) with intent to disrupt, or with reckless 
disregard for the adverse impact on, the orderly conduct of trading 
or the fair execution of transactions;
    (9) engaging in a pattern and practice of submitting 
nonactionable messages for the purpose of seeking to reduce latency;
    (10) submitting intentionally incomplete, corrupted, or 
malformed data; and
    (11) engaging in a pattern and practice of preventing any 
message from reaching an Exchange gateway application and being 
successfully processed.

    The activity identified in proposed Rule 8.23(a) as illegitimate or 
for non-bona fide purposes is currently prohibited by Exchange 
Rules.\9\ The Exchange believes proposed Rule 8.23(a) will provide TPHs 
with clear descriptions of examples of disruptive order and quoting 
entry and trading activity, which will help them avoid engaging in such 
activities or allowing their clients to engage in such activities. 
Proposed Rule 8.23(a) is not meant to define all permutations of 
prohibited disruptive quote and order entry and trading activity; 
however, the Exchange believes it is important to provide TPHs with 
specific details regarding prohibited behavior and that these examples 
are consistent with activity the Exchange has previously identified as 
being disruptive and violations of its Rules.\10\
---------------------------------------------------------------------------

    \9\ See, e.g., Rules 8.1 and 8.6.
    \10\ See, e.g., Cboe Regulatory Circular 22-014 (September 26, 
2022), available at RC22-014 Prearranged Trading and Signaling of 
Imminent Orders (<a href="http://cboe.com">cboe.com</a>); and Cboe Regulatory Circular 22-008 
(March 18, 2022), available at RC22-008 Quote and Order Messaging--
Prohibited Activity (<a href="http://cboe.com">cboe.com</a>).
---------------------------------------------------------------------------

    Proposed Rule 8.23(b) describes various factors the Exchange may 
consider when assessing whether conduct constitutes disruptive or 
manipulative activity and thus violates proposed Rule 8.23, which 
factors include, but are not limited to:
    (1) whether the market participant's intent was to induce others 
to trade when they otherwise would not;
    (2) whether the market participant's intent was to affect a 
price rather than to change the market participant's position;
    (3) whether the market participant's intent was to create 
misleading market conditions;
    (4) the size, number, frequency, and duration of exposure of the 
market participant's actionable or nonactionable messages, as 
applicable;
    (5) the market participant's current and historical order and 
quote entry and trading activity on the Exchange and in related 
markets;
    (6) the impact on other market participants, including others' 
orders and quotes, and market prices;
    (7) the impact on Exchange systems including the certification 
environment;
    (8) whether a market participant enters or cancels orders or 
quotes during the Queuing Period or Opening Rotation (each as 
described in Rule 5.31(a)), or complex orders or quotes prior to or 
during the Complex Order Book (``COB'') Opening Process (as 
described in Rule 5.33(c)), for the purpose of either manipulating 
the expected opening price or attempting to identify the order depth 
in the Book or COB, as applicable, at different price levels;
    (9) general market conditions; and
    (10) industry standards and best practices, including those 
related to automated trading systems.

    The Exchange believes these factors are consistent with the 
prohibited activity described in proposed paragraph (a) that, when 
considered in context, supports whether there was requisite intent for 
the market participant's conduct, for example, to induce another market 
participant to engage in market activity. For example, the volume and 
frequency of a specific activity and the resulting impact on Exchange 
systems can support a finding of intent to impact latency. However, 
high market volatility may cause market participants to modify their 
behavior for legitimate purposes.\11\
---------------------------------------------------------------------------

    \11\ This does not mean that all activity during periods of high 
market volatility is legitimate; rather, the Exchange, when 
reviewing a market participant's activity, will consider whether 
volatility may have caused the market participant to engage in such 
activity to address those market conditions rather than to engage in 
disruptive activity.
---------------------------------------------------------------------------

    Proposed Rule 8.23(c) provides that, absent other factors or 
circumstances, the following activities do not constitute a violation 
of Rule 8.23:

    (1) modification or cancellation of an order or quote initially 
entered with the intent to execute a bona fide transaction in 
response to market changes;
    (2) unintentional or accidental submission of an order or quote;
    (3) making a two-sided market with unequal quantities;
    (4) submission of orders or quotes during the Queuing Period or 
Opening Rotation (each as described in Rule 5.31(a)), or complex 
orders or quotes prior to or during the COB Opening Process (as 
described in Rule 5.33(c)), for the purpose of executing bona fide 
transactions upon the opening of the market;
    (5) entering orders or quotes at various price levels throughout 
the Book or COB, as applicable, to gain priority position and 
subsequently canceling those orders or quotes in response to market 
changes; and
    (6) submitting orders, quotes, and messages in test products for 
legitimate testing purposes.

    Just as the Exchange believes it is beneficial to identify as many 
types of specific activity that are prohibited by the Rules, the 
Exchange believes it is equally beneficial to identify for TPHs as many 
types of activity that do not on their face (absent other factors or 
circumstances) constitute illegitimate or non bona fide quoting or 
trading activity. The Exchange views the activities described in 
proposed paragraph (c) as ones that are for legitimate purposes. For 
example, there are many circumstances in which it is a bona fide 
activity to modify or cancel

[[Page 4648]]

an order, including to respond to changes in the market or increased 
volatility. Additionally, while the Exchange believes market 
participants take steps to minimize erroneous submission of orders, the 
Exchange understands such errors (including those caused by system 
disruptions) occur and do not believe bona fide erroneous activity 
rises to the level of illegitimate actors. Further, the Exchange 
provides a testing environment in the System so TPHs, for example, can 
verify a connection to the System before entering into the production 
(i.e., live) environment. The Exchange notes the activities listed in 
proposed paragraph (c), combined with other facts and circumstances, 
may rise to the level of prohibited activity under proposed paragraph 
(a); however, on their face, the activities listed in proposed 
paragraph (c) are not prohibited by the proposed rule. The Exchange 
believes this may eliminate potential confusion regarding whether 
certain activity is permissible under Exchange Rules.
    Finally, the Exchange proposes to adopt the following 
interpretations and policies to proposed Rule 8.23 to provide TPHs with 
additional information to assist them when determining whether certain 
activity is disruptive and thus prohibited by Rule 8.23. Specifically:

    .01 Execution (full or partial) of an order or quote does not 
automatically cause the order or quote to be considered compliant 
with the Rule but rather is one factor the Exchange may consider.
    .02 For purposes of this Rule, actionable messages are messages 
are messages that can be accepted by the Exchange or another party 
or lead to the execution of a trade or cancellation of an order or 
quote, including order messages and bulk messages. Nonactionable 
messages are those messages submitted to the Exchange that relate to 
a nonactionable event, including, but are not limited to: (a) 
heartbeat messages transmitted to the System; (b) the entry of 
orders, quotes, or other messages in test products other than solely 
for legitimate testing purposes; and (c) messages that are 
incomplete, partial, corrupt, or otherwise unable to be processed by 
the Exchange.
    .03 The Exchange evaluates whether a market participant intended 
to disrupt the orderly conduct of trading or the fair execution of 
transactions or demonstrated a reckless disregard for the orderly 
conduct of trading or the fair execution of transactions only in the 
context of the specific instrument, market conditions, and other 
circumstances present at the time in question. Some factors the 
Exchange may consider when determining whether there was orderly 
conduct or the fair execution of transactions include, but are not 
limited to: (a) a rational relationship between consecutive prices; 
(b) a strong correlation between price changes and the volume of 
trades; (c) levels of volatility that do not dramatically reduce 
liquidity; (d) accurate relationships between the price of a 
derivative and the underlying financial instrument; (e) reasonable 
spreads between contracts for near months and for remote months; and 
(f) the impact to other market participants' ability to trade, 
engage in price discovery or manage risk. Volatility alone is not 
presumptively interpreted as disorderly or disruptive, as market 
volatility can be consistent with markets performing their price 
discovery function.
    .04 Proof of intent is not limited to instances in which a 
market participant admits the market participant's state of mind. If 
conduct more likely than not was intended to produce a prohibited 
disruptive consequence or was reckless, intent may be found. Claims 
of ignorance, or lack of knowledge, are not acceptable defenses to 
intentional or reckless conduct. The Exchange generally will find 
requisite intent if the purpose of the market participant's conduct 
was, for example, to induce another market participant to engage in 
market activity.
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.\12\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \13\ 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. The Exchange 
also believes the proposed rule change is consistent with the Section 
6(b)(5) \14\ requirement that the rules of an exchange not be designed 
to permit unfair discrimination between customers, issuers, brokers, or 
dealers. Further, the Exchange believes the proposed rule change is 
consistent with Section 6(b)(1) of the Act,\15\ which provides that the 
Exchange be organized and have the capacity to be able to carry out the 
purposes of the Act. The Exchange's Rules are required to be ``designed 
to prevent fraudulent and manipulative acts and practices, to promote 
just and equitable principles of trade . . . and, in general, to 
protect investors and the public interest.'' \16\

    \15\ 15 U.S.C. 78f(b)(1).
    \16\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    In particular, the Exchange believes the proposed rule change is 
designed to prevent fraudulent and manipulative acts and practices and 
to promote just and equitable principles of trade, as it provides TPHs 
with additional guidance regarding what conduct constitutes specified 
prohibited fraudulent and manipulative acts and practices and activity 
that is inconsistent with just and equitable principles of trade. As 
noted above, various Rules and the Act currently prohibit disruptive 
order and quote entry and trading activity, manipulative trading 
activity, and conduct that is inconsistent with just and equitable 
principles of trade. While it is not possible to identify all behavior 
that is disruptive or manipulative, the Exchange believes it is 
beneficial to specify as much behavior as practicable that is 
disruptive or manipulative. The Exchange believes the proposed rule 
change provides TPHs with additional context for situations in which 
the Exchange may take disciplinary action against them for certain 
activity as being disruptive, and thus manipulative or unjust. The 
Exchange believes there is no legitimate purpose for the prohibited 
activities set forth in proposed paragraph (a), as they generally 
intend to manipulate market prices, evade exposure and on-Exchange 
competition, or disrupt the Exchange System. Such activity is 
disruptive to the market and other investors and may result in market 
manipulation to the detriment of the market and investors, which 
activity the Exchange Act requires our rules to be designed to 
prevent.\17\
---------------------------------------------------------------------------

    \17\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    The Exchange's determination whether certain activity is disruptive 
or manipulative is generally based on facts and circumstances. 
Therefore, the Exchange believes setting forth not only what 
constitutes prohibited activity but also factors the Exchange considers 
when determining whether activity is prohibited will ultimately benefit 
investors by providing them with further clarity regarding activity 
that is and is not permissible. The Exchange believes this may help 
TPHs avoid engaging in such activities or allowing their clients to 
engage in such activities, which may thus reduce manipulative and 
disruptive activity on the Exchange and ultimately protect investors 
and the public interest. Similarly, the Exchange believes including 
examples of activity that (in the absence of other facts and 
circumstances) is not prohibited under

[[Page 4649]]

proposed Rule 8.23 will similarly provide further clarity to investors 
regarding what activity they may and may not engage in on the Exchange.
    The Exchange also believes the proposed rule change is consistent 
with Section 9(a)(1) of the Act, which provides in relevant part that 
it shall be unlawful for any member of a national securities exchange, 
for the purpose of creating a false or misleading appearance of active 
trading in any security other than a government security, or a false or 
misleading appearance with respect to the market for any such security, 
(A) to effect any transaction in such security which involves no change 
in the beneficial ownership thereof, or (B) to enter an order or orders 
for the purchase of such security with the knowledge that an order or 
orders of substantially the same size, at substantially the same time, 
and at substantially the same price, for the sale of any such security, 
has been or will be entered by or for the same or different parties, or 
(C) to enter any order or orders for the sale of any such security with 
the knowledge that an order or orders of substantially the same size, 
at substantially the same time, and at substantially the same price, 
for the purchase of such security, has been or will be entered by or 
for the same or different parties.\18\ Finally, among other things, the 
activity could also result in a violation of Rule 10b-5 under the Act 
(which prohibits any act, practice, or course of business which 
operates or would operate as a fraud or deceit upon any person, in 
connection with the purchase or sale of any security).\19\ The Exchange 
believes the proposed prohibited activity and factors the Exchange may 
consider when determining whether certain conduct constitutes such 
prohibited activity is consistent with these requirements under the 
Act. For example, identifying activity set forth in proposed 
subparagraphs (a)(3) and (4) (as well as the factor listed in proposed 
subparagraph (b)(6)) may support an Exchange finding that a market 
participant's entry of an order to purchase an option with the 
knowledge that another order selling that option will be entered by or 
for the same or different parties, as prohibited by Section 9(a)(1) 
under the Act. Additionally, the existence of activities as set forth 
in proposed subparagraphs (a)(2), (7), and (8) (coupled with factors 
listed in proposed subparagraphs (b)(1) through (3)) may support an 
Exchange finding that a market participant's activity was intended to 
deceive other market participants, as prohibited by Rule 10b-5 under 
the Act.

    If the Exchange believes a TPH has violated proposed Rule 8.23, 
such alleged violation will be pursued in accordance with the 
Exchange's disciplinary process as set forth in Chapter XIII of the 
Rules (as required by Section 6(b)(1) of the Act, which requires the 
Exchange to be organized and have the capacity to enforce compliance by 
the Exchange's TPHs and persons associated with its TPHs with the Act, 
the rules and regulations thereunder, and the rules of the Exchange, 
and Section 6(b)(7) of the Act, which requires that the rules of an 
exchange ``provide a fair procedure for the disciplining of members and 
persons associated with persons... and the prohibition or limitation by 
the exchange of any person with respect to access to services offered 
by the exchange or a member thereof'').\20\

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 it will apply in the 
same manner to all TPHs. 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 prohibition of disruptive quoting and order entry 
and trading activity will benefit the market as whole. As noted above, 
the Exchange and other exchanges have issued guidance that specifies 
certain behavior that is deemed to be considered violations of those

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 written comments on the 
proposed rule change.

III. Date of Effectiveness of the Proposed Rule Change and Timing for 
Commission Action

    The Exchange has filed the proposed rule change pursuant to Section 
19(b)(3)(A) \22\ of the Act and Rule 19b-4(f)(6) \23\ thereunder. 
Because the foregoing proposed rule change does not: (i) significantly 
affect the protection of investors or the public interest; (ii) impose 
any significant burden on competition; and (iii) become operative prior 
to 30 days from the date on which it was filed, or such shorter time as 
the Commission may designate, if consistent with the protection of 
investors and the public interest, the proposed rule change has become 
effective pursuant to Section 19(b)(3)(A)(iii) of the Act \24\ and Rule 
19b-4(f)(6) thereunder.\25\
---------------------------------------------------------------------------

    \22\ 15 U.S.C. 78s(b)(3)(A).
    \23\ 17 CFR 240.19b-4(f)(6).
    \24\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \25\ 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, along 
with a brief description and text of 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 shall institute proceedings under 
Section 19(b)(2)(B) \26\ of the Act to determine whether the proposed 
rule change should be approved or disapproved.
