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

    In its filing with the Commission, the self-regulatory organization 
included statements concerning the purpose of and basis for the 
proposed rule change and discussed any comments it received on the 
proposed rule change. The text of these statements may be examined at 
the places specified in Item IV below. The self-regulatory organization 
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

1. Purpose
    The Exchange proposes to amend its Fee Schedule to modify the 
Supplemental Market Quality Program (``SMQ'' or the ``Program'') \9\ by 
introducing a second tier of qualifying securities and modifying the 
quoting requirements to make it easier for Members to qualify for the 
SMQ incentive payments. The Program is intended to increase displayed 
liquidity and promote order flow to the Exchange by offering a 
financial incentive for Members to enter displayed orders or quotes 
(i.e., displayed trading interest) priced at the NBBO \10\ on the 
Exchange for a significant portion of the day in certain securities 
designated by the Exchange (``SMQ Securities''). The Exchange now 
proposes to modify the SMQ by: (i) expanding the number of securities 
covered by the current SMQ (as explained below, these securities will 
now be referred to as ``SMQ Level 1 Securities'') and creating a new, 
higher incentive payment tier for certain newly added securities which 
are more difficult to quote (which will be referred to as ``SMQ Level 2 
Securities''); (ii) increasing the minimum number of securities in 
which a Member must have qualifying quoting activity in the current 
Program from 50 securities to 100 securities; and (iii) changing the 
quoting requirements to qualify for the SMQ \11\ by basing qualifying 
quoting activity on a Member's percentage of market hours quoting on 
the NBB \12\ plus that Member's percentage of market hours quoting on 
the NBO.\13\ Notwithstanding the increase in the minimum number of 
securities in which a Member must have qualifying quoting activity, the 
Exchange believes that this change to the quoting requirements will 
make it easier for Members to achieve the minimum threshold required to 
be eligible for payment under the Program because more quoting activity 
will qualify under this proposed change.
---------------------------------------------------------------------------

    \9\ The Exchange filed the proposed rule change establishing the 
SMQ on May 16, 2025. See Securities Exchange Act Release No. 103131 
(May 27, 2025), 90 FR 23397 (June 2, 2025) (SR-IEX-2025-07) (``SMQ 
Product Filing'').
    \10\ See IEX Rule 1.160(u).
    \11\ Currently, if a Member quotes on the NBB and NBO 
concurrently for 20% of market hours, the Member's Percent Time at 
the NBBO would be 20%. Under this proposal, the Percent Time at NBB 
and Percent Time at NBO would be added together and become ``NBBO 
Time.'' In this example, the Member's NBBO Time would be 40%. As set 
forth in SR-IEX-2025-26 (the ``ETP Quoting Filing'') and explained 
infra, IEX proposes to define ``NBBO Time'' as the sum of the 
Member's ``Percent Time at NBB'' and ``Percent Time at NBO.'' And 
IEX proposes to define ``Percent Time at NBB'' and ``Percent Time at 
NBO'' as the aggregate percentage of time during Regular Market 
Hours where a Member has a displayed order of at least one round lot 
at the NBB or NBO, respectively.
    \12\ See IEX Rule 1.160(u).
    \13\ See IEX Rule 1.160(u).
---------------------------------------------------------------------------

Expansion of Securities Covered by the SMQ Program
    As set forth in the SMQ Product Filing, the Exchange determines 
which securities to designate as SMQ Securities by applying several 
objective factors concerning each security's trading characteristics 
and generally designates as SMQ Securities those securities that meet 
certain thresholds with respect to these factors.\14\ These factors 
include IEX's current relative quote presence in each security (i.e., 
displayed order volume and time at the NBBO for each security traded on 
the Exchange), the number of market-wide daily price changes and the 
average market-wide quote size for each security, and each security's 
share price and average notional value traded.\15\ IEX uses these 
factors to assess which securities are suitable for inclusion in the 
list of SMQ Securities, with a goal of identifying securities in which 
increased quoting would be impactful to both IEX and the market, but 
not unduly burdensome to its Members in meeting the quoting 
requirements to qualify for the SMQ.
---------------------------------------------------------------------------

    \14\ As set forth in the SMQ Product Filing, the Exchange 
discussed with Commission staff the thresholds it applies to these 
objective factors. See SMQ Product Filing, supra note 9 at 90 FR at 
23398.
    \15\ See SMQ Product Filing, supra note 9 at 90 FR at 23398.
---------------------------------------------------------------------------

    As noted above, IEX is proposing to expand the number of securities 
included in the list of SMQ Securities. To do so, IEX is adjusting the 
thresholds it applies to the objective criteria described above, but is 
making no changes to the criteria used to assess a security's 
suitability for inclusion in the SMQ.
    IEX also proposes to expand the SMQ by introducing a second tier of 
SMQ Securities, which it proposes to call ``SMQ Level 2 Securities.'' 
SMQ Level 2 Securities will be selected from among the newly added SMQ 
Securities using the same objective criteria used for the current SMQ 
Securities, but the threshold values will be adjusted to select for 
symbols that are more difficult to quote (for example they are 
generally more expensive per share and experience more quote changes). 
As a result, market participants entering displayed trading interest in 
these securities put more capital at risk, potentially face higher risk 
of adverse

[[Page 53039]]

selection, and due to the increased frequency of quote changes, may be 
required to more closely manage their quotes in order to maintain a 
quote at the NBB, NBO, or the NBBO. To incentivize displayed trading 
interest in these SMQ Level 2 Securities, the Exchange proposes to 
provide a higher SMQ Incentive Payment \16\ that will apply to 
qualifying quoting activity in these securities of $400 per qualified 
security per month. In order to receive the SMQ Incentive Payment for 
quoting in SMQ Level 2 Securities, a Member must have an NBBO Time of 
at least 40% in at least 20 or more SMQ Level 2 Securities. The 
Exchange believes that introducing a new, higher incentive fee for the 
SMQ Level 2 Securities would be particularly impactful to IEX and the 
market more generally by increasing quoting competition in securities 
that are relatively more difficult to quote.
---------------------------------------------------------------------------

    \16\ As described infra, ``SMQ Incentive Payment'' shall mean 
``the fixed dollar amount paid per SMQ Security to a Member that 
satisfies the requirements for the SMQ listed herein.''
---------------------------------------------------------------------------

    The Exchange will identify all securities that it determines are 
suitable to be included in the Level 2 tier, and identify them as such 
in the list of SMQ Level 2 Securities that the Exchange will maintain 
on its website. The Exchange also proposes to add to the SMQ section of 
the Fee Schedule a new Calculation Table (the ``SMQ Level 2 Calculation 
Table''), which will specify the above criteria for qualifying for the 
SMQ Incentive Payment based upon quoting activity in SMQ Level 2 
Securities. The new SMQ Level 2 Calculation Table will be as follows:

                      SMQ Level 2 Calculation Table
------------------------------------------------------------------------
 SMQ qualifying activity: average daily
 number of SMQ Level 2 securities with        SMQ incentive payment
      an NBBO Time of at least 40%
------------------------------------------------------------------------
0-19...................................  $0 per qualified security per
                                          month.
20 or more SMQ Level 2 Securities **...  $400 per qualified security per
                                          month.
------------------------------------------------------------------------
** SMQ Payouts will be made for all qualified securities if Member had
  SMQ Qualifying Activity in at least 20 SMQ Level 2 Securities during
  the month.

    To distinguish the SMQ Level 2 Securities from the rest of the SMQ 
Securities, IEX proposes to rename the first tier of SMQ qualifying 
securities from ``SMQ Securities'' to ``SMQ Level 1 Securities,'' and 
revise the definition of ``SMQ Securities'' to include SMQ Level 1 and 
Level 2 Securities. Thus, as proposed, the SMQ section of the Fee 
Schedule will contain the following definitions of SMQ Securities:
     ``SMQ Securities'' shall mean either SMQ Level 1 or SMQ 
Level 2 Securities, as defined below.
     ``SMQ Level 1 Securities'' shall mean a list of securities 
designated as such, that are used for purposes of qualifying for the 
SMQ. The universe of these securities will be determined by the 
Exchange and published on the Exchange's website here. Prior to the 
start of each month, the Exchange will reevaluate and, as applicable, 
update its list of SMQ Level 1 Securities, and it will publish the 
updated list on the Fee Schedule at least one day prior to the start of 
the month.
     ``SMQ Level 2 Securities'' shall mean a list of securities 
designated as such, that are used for purposes of qualifying for the 
SMQ. The universe of these securities will be determined by the 
Exchange and published on the Exchange's website here. Prior to the 
start of each month, the Exchange will reevaluate and, as applicable, 
update its list of SMQ Level 2 Securities, and it will publish the 
updated list on the Fee Schedule at least one day prior to the start of 
the month.
Increasing the Quoting Activity Required To Qualify for SMQ Level 1 
Securities
    To qualify for the SMQ Incentive Payment currently, a Member must 
enter displayed trading interest (i.e., at least one displayed order or 
quote of at least one round lot size) at either the NBB, the NBO, or 
the NBBO, for at least 40% of time during regular market hours \17\ in 
at least 50 of the SMQ Level 1 Securities (based on an average daily 
number) during the month. The Exchange proposes to increase the average 
daily number of SMQ Level 1 Securities in which a Member must have the 
minimum amount of qualifying quoting activity from 50 SMQ Securities to 
100 SMQ Level 1 Securities. The Exchange also proposes to rename the 
current SMQ Calculation Table in the SMQ section of the Fee Schedule as 
the ``SMQ Level 1 Calculation Table'', and to update the text as 
follows:
---------------------------------------------------------------------------

    \17\ In the ETP Quoting Filing (SR-IEX-2025-26), the Exchange 
amended references to ``regular trading hours'' in the Fee Schedule 
to ``Regular Market Hours.''

                      SMQ Level 1 Calculation Table
------------------------------------------------------------------------
 SMQ qualifying activity: average daily
 number of SMQ Level 1 securities with        SMQ incentive payment
      an NBBO Time of at least 40%
------------------------------------------------------------------------
0-99...................................  $0 per qualified security per
                                          month.
100 or more SMQ Level 1 Securities *...  $125 per qualified security per
                                          month.
------------------------------------------------------------------------
* SMQ Payouts will be made for all qualified securities if Member had
  SMQ Qualifying Activity in at least 100 SMQ Level 1 Securities during
  the month.

    The Exchange believes this increase is commensurate with the other 
modifications described herein, namely the increase in the number of 
securities that will be on the SMQ Level 1 Securities list, as 
described above, and the manner in which IEX will make it easier for 
Members to meet the quoting requirements, as described below. While 
this increase will require Members to engage in more quoting activity 
to qualify for SMQ Payments, Members will now have a larger number of 
securities in which to quote and, as described below, more relaxed 
quoting requirements. Taken together, the Exchange believes these 
changes will make it easier for Members to satisfy the

[[Page 53040]]

minimum requirements. In addition, the Exchange believes that 
increasing the minimum average daily number of SMQ Level 1 Securities 
is appropriate to ensure the continuing effectiveness of the SMQ 
Program in improving trading conditions for all market participants 
through increased quoting competition on the Exchange in a larger 
number of securities.
    The Exchange also proposes to revise two defined terms in the SMQ 
section of the Fee Schedule for clarity and consistency. Specifically, 
IEX proposes to rename the ``SMQ Incentive Fee'' as the ``SMQ Incentive 
Payment.'' IEX proposes to make this change because it is a more 
accurate description of the payments Members receive for participation 
in the SMQ, which are in fact payments, not fees charged to them. 
Consistent with this change, IEX proposes to revise the right-hand 
column in the SMQ Calculation Tables to now refer to the ``SMQ 
Incentive Payment.'' To avoid any potential confusion, IEX proposes to 
rename the otherwise-similarly named term ``SMQ Payment'' as the ``SMQ 
Payout'', and to update the footnote to both SMQ Calculation Tables to 
now refer to SMQ Payouts. These proposed changes are designed to 
improve the clarity and accuracy of the SMQ section of the Fee 
Schedule.
Expansion of SMQ Qualifying Quoting Activity
    Currently, a Member qualifies for the SMQ by entering displayed 
trading interest at either the NBB, the NBO, or the NBBO, for at least 
40% of time during regular market hours in at least 50 of the SMQ 
Securities on average per day during the month (the ``Percent Time at 
NBBO'' requirement). The Exchange calculates the number of SMQ 
Securities for which each Member's Percent Time at NBBO was at least 
40% (``SMQ Qualifying Activity'') on a daily basis. At the end of the 
month, the Exchange calculates the monthly average of the number of SMQ 
Securities in which the Member had SMQ Qualifying Activity. If a 
Member, on an average daily basis, has SMQ Qualifying Activity in at 
least 50 of the SMQ Securities during the month, the Exchange pays the 
Member the ``SMQ Incentive Payment'' of $125 per SMQ Security for which 
the Member satisfied the SMQ requirements.\18\
---------------------------------------------------------------------------

    \18\ Currently, the Exchange pays SMQ Payments for all qualified 
securities if the Member had SMQ Qualifying Activity in at least 50 
SMQ Securities during the month.
---------------------------------------------------------------------------

    As discussed above, the Exchange proposes to change the quoting 
requirements to qualify for the SMQ by basing qualifying quoting 
activity on a Member's NBBO Time: the Member's percentage of market 
hours quoting on the NBB plus the Member's percentage of market hours 
quoting on the NBO. For example, for a particular security, if a 
Member's Percent Time at NBB is 25% and Percent Time at NBO is 15%, its 
NBBO Time would be 40%. Alternatively, if a Member's Percent Time at 
NBB is 20% and concurrently, the Member's Percent Time at NBO is also 
20%, then that Member's NBBO Time also would be 40%. Put differently, 
quoting activity on either side of the NBBO will now count toward the 
relevant eligibility threshold.
    In a rule filing filed by the Exchange concurrently with this 
one,\19\ the Exchange moved certain terms and definitions in the SMQ 
section of the Fee Schedule that were applicable to other parts of the 
Fee Schedule to the Definitions and Notes subheadings of the 
Transaction Fees section of the Fee Schedule. Thus, the term ``Percent 
Time at NBBO'' has been removed from the Fee Schedule and replaced with 
the terms ``Percent Time at NBB,'' \20\ ``Percent Time at NBO'' \21\ 
and ``NBBO Time'' \22\ which appear in the ``Definitions'' subheading 
of the Transaction Fees section of the Fee Schedule. Additionally, the 
ETP Quoting Filing moved the language about trading days and hours that 
are excluded from the quoting calculations as well as how Members can 
aggregate their activity with their affiliates from the SMQ section of 
the Fee Schedule to the Notes subheading of the Transaction Fees 
section of the Fee Schedule. IEX also modified the language, so that it 
now describes how the Exchange applies these exclusions and 
aggregations to the SMQ as well as to certain other quoting and trading 
based fee incentives. For clarity purposes, IEX proposes to add a 
bullet under the ``Supplemental Market Quality Program'' subheading 
that reads:
---------------------------------------------------------------------------

    \19\ See ETP Quoting Filing (SR-IEX-2025-26).
    \20\ The Fee Schedule defines this term as ``the aggregate of 
the percentage of time during Regular Market Hours where a Member 
has a displayed order of at least one round lot at the national best 
bid (`NBB').''
    \21\ The Fee Schedule defines this term as ``the aggregate of 
the percentage of time during Regular Market Hours where a Member 
has a displayed order of at least one round lot at the national best 
offer (`NBO').''
    \22\ The Fee Schedule defines this term as ``the Member's 
Percent Time at NBB plus the Member's Percent Time at NBO. For 
example, for a particular security, if a Member's Percent Time at 
NBB is 25% and Percent Time at NBO is 15%, its NBBO Time would be 
40%. Alternatively, if a Member's Percent Time at NBB is 20% and 
concurrently, the Member's Percent Time at NBO is also 20%, then 
that Member's NBBO Time would be 40%.''

    Please refer to the Definitions and Notes sections located at 
the beginning of the Transaction Fees section for the definition of 
NBBO Time as well as information about how the Exchange calculates 
NBBO Time and allows Members to aggregate their NBBO Time with their 
---------------------------------------------------------------------------
affiliates.

    The effect of these proposed changes will be to relax the quoting 
activity requirements to qualify for the SMQ Program so that any 
quoting activity at the NBB or the NBO (or NBB and NBO combined) will 
count toward the eligibility threshold. The Exchange believes that this 
proposed change will make it easier for Members to qualify for, and 
expand opportunities to participate in, the Program, thereby providing 
enhanced liquidity for all market participants through increased 
displayed trading interest and narrower bid-ask spreads on the 
Exchange.
    All other aspects of calculating a Member's eligibility for SMQ 
payments remain unchanged. As the Exchange does currently, on a daily 
basis the Exchange will calculate the average daily number of SMQ Level 
1 Securities in which the Member had SMQ Qualifying Activity based on 
the Member's daily quoting activity. For clarity and consistency, IEX 
proposes to modify the definition of SMQ Qualifying Activity in the SMQ 
section of the Fee Schedule to read as follows:

    ``SMQ Qualifying Activity'': As described in the Notes section, 
above, on a daily basis, the Exchange will determine the number of 
SMQ Level 1 and/or Level 2 Securities in which a Member meets the 
threshold for NBBO Time set forth in the below SMQ Calculation 
Tables. At the end of the month, the Exchange will calculate the SMQ 
Qualifying Activity by taking the average (rounded to the nearest 
whole number) of the number of SMQ Level 1 and/or Level 2 Securities 
for which the Member's NBBO Time was at least the threshold value 
set forth in the Calculation Tables below.

    The relevant text in the Notes section referred to in the 
definition of SMQ Qualifying Activity \23\ reads as follows:
---------------------------------------------------------------------------

    \23\ This text was added to the Fee Schedule by the ETP Quoting 
Filing.

    Unless otherwise specified, for any tiers that include NBBO Time 
as a required criteria (for example, the Displayed Liquidity Adding 
Rebate Tiers in footnote 4 and the Supplemental Market Quality 
Program), on a daily basis, the Exchange will determine the number 
of securities in which a Member meets the threshold value (set forth 
in the tier) for NBBO Time for that day. At the end of the month, 
the Exchange will take the average (rounded to the nearest whole 
number) of the number of securities in which a Member's NBBO Time 
was at least the

[[Page 53041]]

---------------------------------------------------------------------------
threshold value set forth in the applicable tier.

    In summary, if a Member has SMQ Qualifying Activity in an average 
of at least 100 of the SMQ Level 1 Securities during the month, the 
Exchange will pay the Member $125 per qualified security.\24\ If a 
Member has SMQ Qualifying Activity in an average of at least 20 SMQ 
Level 2 Securities, the Exchange will pay the Member $400 per qualified 
security. Furthermore, both SMQ Level 1 and Level 2 Calculation Tables 
will have a footnote explaining that SMQ Payments will be made for all 
qualified securities if the Member had SMQ Qualifying Activity in at 
least the threshold number of SMQ Securities during the month.
---------------------------------------------------------------------------

    \24\ The SMQ Incentive Payment for SMQ Level 1 Securities will 
remain unchanged at $125 per qualified security.
---------------------------------------------------------------------------

    The following examples illustrate how the amended SMQ will work.
Example No. 1 (SMQ Level 1 Securities)
    Assume that in a particular month, IEX has designated 500 
securities as SMQ Level 1 Securities. There are 20 trading days in that 
month, and on ten of those days Member A's NBBO Time is 40% for 200 of 
the SMQ Level 1 Securities. On the other ten trading days, Member A's 
NBBO Time is 40% for 100 of the SMQ Securities. At the end of the 
month, IEX calculates the average number of SMQ Securities in which 
Member A has at least 40 Percent NBBO Time on a daily basis to be 150 
SMQ Level 1 Securities. IEX provides a lump sum payment of $18,750 to 
Member A ($125 x 150 SMQ Level 1 Securities) (the ``SMQ Payment'').
Example No. 2 (SMQ Level 2 Securities)
    Assume that in a particular month, IEX has designated 100 
securities as SMQ Level 2 Securities. There are 21 trading days in that 
month, and on eleven of those days Member B's NBBO Time is 40% for 25 
of the SMQ Level 2 Securities. On the other ten trading days, Member 
B's NBBO Time is 40% for 30 of the SMQ Level 2 Securities. At the end 
of the month, IEX calculates the average daily number of SMQ Level 2 
Securities in which Member B had at least 40 Percent NBBO Time to be 27 
\25\ SMQ Level 2 Securities. IEX provides a lump sum payment of $10,800 
to Member B ($400 x 27 SMQ Level 2 Securities) (the ``SMQ Payment'').
---------------------------------------------------------------------------

    \25\ As set forth in the proposed Fee Schedule, the Exchange 
will calculate the SMQ Qualifying Activity by taking the average of 
the number of SMQ Level 2 Securities for which the Member's NBBO 
Time was at least 40% and round that number to the nearest whole 
number. Thus, 27.38 SMQ Securities is rounded to 27.
---------------------------------------------------------------------------

    As noted above, the Exchange will apply the same exclusions to the 
calculation of NBBO Time that currently apply to the SMQ (e.g., 
excluding time periods of system disruptions, days with scheduled early 
market close, or any regular market hours when an SMQ Security is 
subject to a trading halt or Limit Up-Limit Down pause).\26\ For 
example, if an SMQ Security was halted for 30 minutes during one 
trading day, and a Member provided displayed trading interest in that 
security at the NBB (NBO) for 2.4 hours of that trading day, the 
Member's Percent Time at NBB (NBO) for that day would be 40%, because 
2.4 hours is 40% of 6 hours.\27\
---------------------------------------------------------------------------

    \26\ See, e.g., IEX Rules 11.271 and 11.280.
    \27\ If IEX did not exclude the time a security is halted from 
its calculation of Percent Time at NBB (NBO), in this example the 
Member's Percent Time at NBB (NBO) would be 37% (2.4 hours divided 
by the full 6.5 hour trading day), and the Member's trading activity 
in that security for that day would not count towards its SMQ 
Qualifying Activity.
---------------------------------------------------------------------------

    The Exchange will continue to allow Members to aggregate their 
Percent Time at NBB and their Percent Time at NBO (and thus their NBBO 
Time) with other Members with which they are affiliated,\28\ if Members 
provide prior notice to the Exchange. As proposed, to the extent that 
two or more affiliated companies maintain separate memberships with the 
Exchange and can demonstrate their affiliation by showing they control, 
are controlled by, or are under common control with each other, the 
Exchange would permit such Members to aggregate their Percent Time at 
NBB (and their Percent Time at NBO). Members will be responsible for 
having proper internal documentation in their books and records 
substantiating that the two or more Members seeking to aggregate their 
Percent Time at NBB and their Percent Time at NBO are affiliates of one 
another.
---------------------------------------------------------------------------

    \28\ As defined in Rule 12b-2 under the Act, 17 CFR 240.12b-2.
---------------------------------------------------------------------------

    The SMQ, as amended with the changes described herein, will remain 
open to all Members and will not impose any two-sided quotation 
obligations on any Member seeking to qualify for the SMQ. Accordingly, 
the amended SMQ will continue to be designed to attract liquidity from 
any firm willing to provide liquidity at the NBB or NBO in SMQ Level 1 
or Level 2 Securities. Through these proposed changes, the Exchange is 
proposing to increase opportunities for Members to earn an SMQ Payment 
by increasing the number of securities in the Program, offering an 
increased incentive payment for displayed trading interest in 
relatively more difficult-to-quote securities, and changing the quoting 
activity calculation to count time quoting at either the NBB or the NBO 
as the basis for the SMQ Qualifying Activity, thereby making it easier 
to satisfy the quoting activity requirement. As noted in the SMQ 
Product Filing, the SMQ Program is similar to quote incentive programs 
at other national securities exchanges.\29\
---------------------------------------------------------------------------

    \29\ See SMQ Product Filing, supra note 9, 90 FR at 23400 
(comparing the SMQ to the Enhanced Market Quality Program offered by 
Nasdaq BX, the Market Quality program offered by MIAX PEARL, and 
Cboe EDGA's NBBO Setter Program); see also LTSE's Liquidity 
Incentive Program, available at https://ltse.com/trading/fee-schedules.

2. Statutory Basis
    IEX believes that the proposed rule change is consistent with the 
provisions of Section 6(b) \30\ of the Act in general, and furthers the 
objectives of Sections 6(b)(4) \31\ of the Act, in particular, in that 
it is designed to provide for the equitable allocation of reasonable 
dues, fees and other charges among its Members and other persons using 
its facilities. The Exchange believes that the proposed fee change is 
reasonable, fair and equitable, and non-discriminatory.
---------------------------------------------------------------------------

    \30\ 15 U.S.C. 78f.
    \31\ 15 U.S.C. 78f(b)(4).
---------------------------------------------------------------------------

    The Exchange operates in a highly competitive market in which 
market participants can readily direct order flow to competing venues 
if they deem fee levels at a particular venue to be excessive. Based 
upon informal discussions with Members regarding the current SMQ 
Program, IEX has concluded that it will be able to more effectively 
compete with other exchanges for order flow by expanding the list of 
SMQ-eligible securities; offering Members an increased incentive 
payment for posting displayed liquidity on the Exchange in securities 
that are relatively more difficult-to-quote compared to other 
securities; and relaxing the quoting activity that qualifies for the 
SMQ. IEX believes that Members and other market participants may be 
more willing to send displayed trading interest to IEX if the proposed 
rule changes are adopted.
    Accordingly, IEX has designed the proposed changes to further 
incentivize Members to send displayed quotes at the NBB (NBO) in a 
wider range of securities and specifically, in lower displayed volume 
securities. IEX believes that an increase in displayed liquidity and 
order flow to the Exchange will, in turn, improve the quality of the 
IEX market and increase its attractiveness to existing and prospective 
participants. In addition,

[[Page 53042]]

the proposal is equitable and not unfairly discriminatory as the 
proposal would equitably allocate SMQ Payments among Members by paying 
Members based on their total quoting activity in SMQ Level 1 Securities 
and SMQ Level 2 Securities in any given month.
    As noted in the Purpose section, the Exchange believes the proposed 
incentive payments in the Supplemental Market Quality Program will 
incentivize Members to direct additional displayed liquidity-providing 
orders to the Exchange in SMQ Securities, thereby promoting price 
discovery and market quality in the SMQ Securities and more generally 
on the Exchange, and, further, that the resulting increased displayed 
liquidity and narrower spreads will benefit all investors by deepening 
the Exchange's liquidity pool, supporting the quality of price 
discovery, enhancing quoting competition across all exchanges, and 
promoting market transparency.
    As discussed above, the Exchange operates in a highly competitive 
market in which market participants can readily direct order flow to 
competing venues if they deem fee levels at a particular venue to be 
excessive. The SMQ is comparable to quote incentive programs at other 
exchanges and thus IEX does not believe that the proposal raises any 
new or novel issues not already considered by the Commission in the 
context of other exchanges' fees.\32\ To the extent this proposed fee 
change is successful in incentivizing the entry and execution of 
displayed trading interest on IEX, such greater liquidity will benefit 
all market participants by increasing price discovery and price 
formation as well as market quality and execution opportunities.
---------------------------------------------------------------------------

    \32\ See supra note 29.
---------------------------------------------------------------------------

    Finally, the Exchange believes that the textual changes to the Fee 
Schedule, specifically moving some definitions to the Transaction Fees 
section of the Fee Schedule and updating definitions in the SMQ section 
of the terms ``SMQ Qualifying Activity'', ``SMQ Incentive Payments'', 
and ``SMQ Payouts''; is consistent with the requirements above. These 
proposed changes are designed to reduce any potential confusion for 
market participants using IEX's Fee Schedule and to provide clarity, 
accuracy, and consistency between the Fee Schedule and the Rule Book. 
Further, IEX believes these changes would contribute to reasonably 
ensuring that the requirements of the SMQ Program, and any other 
activity-based incentive or rebate described in the Fee Schedule, are 
clear, accurate, and consistent with the Rule Book.

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

    IEX does not believe that the proposed rule change will result in 
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 intermarket 
competition that is not necessary or appropriate in furtherance of the 
purposes of the Act. The Exchange operates in a highly competitive 
market in which market participants can readily favor competing venues 
if fee schedules at other venues are viewed as more favorable. 
Consequently, the Exchange believes that the degree to which IEX fees 
could impose any burden on competition is extremely limited and does 
not believe that such fees would burden competition between Members or 
competing venues. Moreover, as noted in the Statutory Basis section, 
the Exchange does not believe that the proposed changes raise any new 
or novel issues not already considered by the Commission.
    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, while 
different Members may qualify for different amounts of SMQ Payments, 
these payments are not based on the type of Member entering the 
displayed trading interest, but rather on the amount of displayed 
trading interest in a wide range of eligible securities that each 
Member submits to the Exchange. Further, the proposed fee changes are 
intended to incentivize market participants to bring increased order 
flow to the Exchange, which benefits all market participants.
