[Release No. 34-103026; File No. SR-MEMX-2025-10]


Self-Regulatory Organizations; MEMX LLC; Notice of Filing and 
Immediate Effectiveness of a Proposed Rule Change To Amend the 
Exchange's Fee Schedule Concerning Equities Transaction Pricing

May 12, 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 April 30, 2025, MEMX LLC (``MEMX'' or the ``Exchange'') filed 
with the Securities and Exchange Commission (the ``Commission'') the 
proposed rule change as described in Items I, II, and III below, which 
Items have been prepared by the Exchange. The Commission is publishing 
this notice to solicit comments on the proposed rule change from 
interested persons.

I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    The Exchange is filing with the Commission a proposed rule change 
to amend the Exchange's fee schedule applicable to Members \3\ (the 
``Fee Schedule'') pursuant to Exchange Rules 15.1(a) and (c). As is 
further described below, the Exchange proposes to (i) reduce the rebate 
provided under Liquidity Provision Tier 1 for executions of orders in 
securities priced at or above $1.00 per share that add displayed 
liquidity to the Exchange (such orders, ``Added Displayed Volume''); 
(ii) modify the required criteria under Non-Display Add Tier 2; (iii) 
reduce the rebate provided under the Displayed Liquidity Incentive 
(``DLI'') Tier 1; and (iv) eliminate the Liquidity Removal Tier. The 
Exchange proposes to implement the changes to the Fee Schedule pursuant 
to this proposal immediately. The text of the proposed rule change is 
provided in Exhibit 5.
---------------------------------------------------------------------------

    \3\ See Exchange Rule 1.5(p).
---------------------------------------------------------------------------

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 purpose of the proposed rule change is to amend the Fee 
Schedule to: (i) reduce the rebate provided under Liquidity Provision 
Tier 1 for executions of orders in securities priced at or above $1.00 
per share that add displayed liquidity to the Exchange (such orders, 
``Added Displayed Volume''); (ii) modify the required criteria under 
Non-Display Add Tier 2; (iii) reduce the rebate provided under the 
Displayed Liquidity Incentive (``DLI'') Tier 1; and (iv) eliminate the 
Liquidity Removal Tier.
    The Exchange first notes that it 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 or incentives to be insufficient. More specifically, the 
Exchange is only one of 18 registered equities exchanges, as well as a 
number of alternative trading systems and other off-exchange venues, to 
which market participants may direct their order flow. Based on 
publicly available information, no single registered equities exchange 
currently has more than approximately 14.1% of the total market share 
of executed volume of equities trading.\4\ Thus, in such a low-
concentrated and highly competitive market, no single equities exchange 
possesses significant pricing power in the execution of order flow, and 
the Exchange currently represents approximately 2.4% of the overall

[[Page 21095]]

market share.\5\ The Exchange in particular operates a ``Maker-Taker'' 
model whereby it provides rebates to Members that add liquidity to the 
Exchange and charges fees to Members that remove liquidity from the 
Exchange. The Fee Schedule sets forth the standard rebates and fees 
applied per share for orders that add and remove liquidity, 
respectively. Additionally, in response to the competitive environment, 
the Exchange also offers tiered pricing, which provides Members with 
opportunities to qualify for higher rebates or lower fees where certain 
volume criteria and thresholds are met. Tiered pricing provides an 
incremental incentive for Members to strive for higher tier levels, 
which provides increasingly higher benefits or discounts for satisfying 
increasingly more stringent criteria.

    \5\ Id.
---------------------------------------------------------------------------

Reduced Rebate Under Liquidity Provision Tier 1
    The Exchange currently provides a base rebate of $0.0015 per share 
for executions of Added Displayed Volume.\6\ The Exchange also 
currently offers Liquidity Provision Tiers 1-5 under which a Member may 
receive an enhanced rebate for executions of Added Displayed Volume by 
achieving the corresponding required volume criteria for each such 
tier. The Exchange now proposes to modify Liquidity Provision Tier 1 by 
reducing the rebate provided under such tier. Currently, under 
Liquidity Provision Tier 1, the Exchange provides an enhanced rebate of 
$0.0034 per share for executions of Added Displayed Volume for Members 
that qualify for such tier by either: (1) achieving an ADAV \7\ 
(excluding Retail Orders) that is equal to or greater than 0.40% of the 
TCV; \8\ or (2) achieving an ADAV that is equal to or greater than 
0.30% of the TCV in securities priced at or above $1.00 per share and a 
Non-Displayed ADAV \9\ that is equal to or greater than 6,000,000 
shares. The Exchange now proposes to reduce the rebate provided under 
Liquidity Provision Tier 1 for executions of Added Displayed Volume 
from $0.0034 per share to $0.0033 per share.\10\ The Exchange believes 
that the proposed rebate represents only a modest decrease from the 
current rebate provided under Liquidity Provision Tier 1 for executions 
of Added Displayed Volume. The purpose of reducing the enhanced rebate 
for executions of Added Displayed Volume under Liquidity Provision Tier 
1 is for business and competitive reasons, as the Exchange believes the 
reduction of such rebate would decrease the Exchange's expenditures 
with respect to its transaction pricing in a manner that is still 
consistent with the Exchange's overall pricing philosophy of 
encouraging added displayed liquidity. The Exchange does not propose to 
change the required criteria for a Member to qualify for Liquidity 
Provision Tier 1 or the rebate provided under Liquidity Provision Tier 
1 for executions of orders in securities priced below $1.00 per share.
---------------------------------------------------------------------------

    \6\ The base rebate for executions of Added Displayed Volume is 
referred to by the Exchange on the Fee Schedule under the existing 
description ``Added displayed volume'' with a Fee Code of ``B'', 
``D'' or ``J'', as applicable, on execution reports.
    \7\ As set forth on the Fee Schedule, ``ADAV'' means the average 
daily added volume calculated as the number of shares added per day, 
which is calculated on a monthly basis, and ``Displayed ADAV'' means 
ADAV with respect to displayed orders.
    \8\ As set forth on the Fee Schedule, ``TCV'' means total 
consolidated volume calculated as the volume reported by all 
exchanges and trade reporting facilities to a consolidated 
transaction reporting plan for the month for which the fees apply.
    \9\ As set forth on the Fee Schedule, ``Non-Displayed ADAV'' 
means ADAV with respect to non-displayed orders (including orders 
subject to Display-Price Sliding that receive price improvement when 
executed and Midpoint Peg orders).
    \10\ The proposed pricing for Liquidity Provision Tier 1 is 
referred to by the Exchange on the Fee Schedule under the existing 
description ``Added displayed volume, Liquidity Provision Tier 1'' 
with a Fee Code of ``B1'', ``D1'' or ``J1'', as applicable, to be 
provided by the Exchange on the monthly invoices provided to 
Members.
---------------------------------------------------------------------------

Modified Criteria Under Non-Display Add Tier 2
    The Exchange currently offers Non-Display Add Tiers 1-2 under which 
a Member may receive an enhanced rebate for executions of Added Non-
Displayed Volume in securities priced at or above $1.00 per share by 
achieving the corresponding required volume criteria for each such 
tier. Currently, a Member qualifies for Non-Display Add Tier 2, and 
thus receives an enhanced rebate of $0.0025 per share for executions of 
Added Non-Displayed Volume under such tier, by achieving a Non-
Displayed ADAV that is equal to or greater than 1,000,000 shares.\11\ 
The Exchange now proposes to modify Non-Display Add Tier 2 such that a 
Member would now qualify for such tier by achieving a Non-Displayed 
ADAV that is equal to or greater than 2,000,000 shares. The Exchange is 
not proposing to change the rebate provided under this tier or the 
rebate provided under this tier for executions of orders in securities 
priced below $1.00 per share.
---------------------------------------------------------------------------

    \11\ The pricing for Non-Display Add Tier 2 is referred to by 
the Exchange on the Fee Schedule under the existing description 
``Added non-displayed volume, Non-Display Add Tier 2'' with a Fee 
Code of ``H2'', ``M2'' or ``P2'', as applicable, to be provided by 
the Exchange on the monthly invoices provided to Members.
---------------------------------------------------------------------------

    The Exchange notes that currently, the Fee Schedule indicates that 
Members that qualify for Non-Display Add Tier 2 based on activity in a 
given month will also receive that associated Non-Display Add Tier 2 
rebate during the following month. The Exchange wishes to keep this 
procedure intact, and as such, if a Member met the criteria to receive 
the enhanced rebate under Non-Display Add Tier 2 in April 2025 (i.e., 
by achieving a Non-Displayed ADAV that is equal to or greater than 
1,000,000 shares), the Exchange will provide the enhanced rebate of 
$0.0025 per share for that Member's qualifying executions in April 2025 
and May 2025, regardless of whether the Member meets the newly 
increased criteria requiring a Non-Displayed ADAV that is equal to or 
greater than 2,000,000 shares during May 2025. If that same Member 
meets the newly proposed criteria under the Non-Displayed Add Tier 2 
during the month of May 2025, it will also receive that rebate for its 
qualifying executions in the following month.
    The tiered pricing structure for executions of Added Non-Displayed 
Volume under the Non-Display Add Tiers provides an incremental 
incentive for Members to strive for higher volume thresholds to receive 
higher enhanced rebates for such executions and, as such, is intended 
to encourage Members to maintain or increase their order flow, 
particularly in the form of liquidity-adding non-displayed volume, to 
the Exchange, thereby contributing to a deeper and more robust and 
well-balanced market ecosystem to the benefit of all Members and market 
participants.
Reduced Rebate Under DLI Tier 2
    The Exchange currently offers DLI Tiers 1 and 2 under which a 
Member may receive an enhanced rebate for executions of Added Displayed 
Volume by achieving the corresponding required criteria for each such 
tier. The DLI Tiers are designed to encourage Members, through the 
provision of an enhanced rebate for executions of Added Displayed 
Volume, to promote price discovery and market quality by quoting at the 
NBBO for a significant portion of each day (i.e., through the 
applicable quoting requirement \12\) in a broad base

[[Page 21096]]

of securities (i.e., through the applicable securities requirement 
\13\), thereby benefitting the Exchange and investors by providing 
improved trading conditions for all market participants through 
narrower bid-ask spreads and increased depth of liquidity available at 
the NBBO in a broad base of securities and committing capital to 
support the execution of orders.\14\ Now, the Exchange proposes to 
modify DLI Tier 1 by reducing the rebate for executions of Added 
Displayed Volume under such tier.
---------------------------------------------------------------------------

    \12\ As set forth on the Fee Schedule, the term ``quoting 
requirement'' means the percentage of NBBO Timer required under the 
relevant criteria, and the term ``NBBO Time'' means the aggregate of 
the percentage of time during regular trading hours during which one 
of a Member's market participant identifiers (``MPIDs'') has a 
displayed order of at least one round lot at the national best bid 
or the national best offer.
    \13\ As set forth on the Fee Schedule, the term ``securities 
requirement'' means the requirement that a Member meets the quoting 
requirement in the applicable number of securities per trading day. 
Currently, each of DLI Tiers 1 and 2 has a securities requirement 
that may be achieved by a Member meeting the quoting requirement in 
the specified number of securities traded on the Exchange.
    \14\ See the Exchange's Fee Schedule (available at https://info.memxtrading.com/fee-schedule/) for additional details regarding 
the Exchange's DLI Tiers. See also Securities Exchange Act Release 
No. 92150 (June 10, 2021), 86 FR 32090 (June 16, 2021) (SR-MEMX-
2021-07) (notice of filing and immediate effectiveness of fee 
changes adopted by the Exchange, including the adoption of DLI).
---------------------------------------------------------------------------

    Currently, under DLI Tier 1, the Exchange provides an enhanced 
rebate of $0.0034 per share for executions of Added Displayed Volume 
for Members that qualify for such tier by achieving an NBBO Time of at 
least 50% in an average of at least 1,000 securities per trading day 
during the month. The Exchange proposes to reduce the rebate provided 
under DLI Tier 1 for executions of Added Displayed Volume from $0.0034 
per share to $0.0033 per share.\15\ The Exchange believes that the 
proposed rebate represents only a modest decrease from the current 
rebate provided under DLI Tier 1 for executions of Added Displayed 
Volume. The Exchange does not propose to change the required criteria 
for a Member to qualify for DLI Tier 1 or the rebate provided under DLI 
Tier 1 for executions of orders in securities priced below $1.00 per 
share.
---------------------------------------------------------------------------

    \15\ The proposed pricing for DLI Tier 1 is referred to by the 
Exchange on the Fee Schedule under the existing description ``Added 
displayed volume, DLI Tier 1'' with a Fee Code of ``Bq1'', ``Dq1'' 
or ``Jq1'', as applicable, to be provided by the Exchange on the 
monthly invoices provided to Members.
---------------------------------------------------------------------------

    The purpose of reducing the enhanced rebate for executions of Added 
Displayed Volume under DLI Tier 1 is for business and competitive 
reasons, as the Exchange believes the reduction of such rebate would 
decrease the Exchange's expenditures with respect to its transaction 
pricing in a manner that is still consistent with the Exchange's 
overall pricing philosophy of encouraging added displayed liquidity and 
promoting the price discovery and market quality objectives of the DLI 
Tiers described above.
Eliminate Liquidity Removal Tier
    Finally, the Exchange proposes to eliminate the Liquidity Removal 
Tier. The Exchange currently charges a standard fee of $0.0030 per 
share for executions of orders in securities priced at or above $1.00 
per share that remove liquidity from the Exchange (such orders, 
``Removed Volume''). The Exchange also currently offers Liquidity 
Removal Tier 1 under which qualifying Members are charged a discounted 
fee by achieving the corresponding required volume criteria for each 
such tier. Specifically, under Liquidity Removal Tier 1, the Exchange 
charges a reduced fee of $0.0029 per share for executions of Removed 
Volume by achieving: (1) an ADV \16\ that is equal to or greater than 
0.70% of the TCV and (2) a Remove ADV \17\ that is equal to or greater 
than 0.50% of the TCV. The Exchange now proposes to eliminate the 
Liquidity Removal Tier, as the incentive is not achieving the level of 
participation that the Exchange expected, and thus, is not 
accomplishing the goal that the Exchange had when initially adopting 
this incentive. The Exchange therefore no longer wishes to, nor is it 
required to, maintain such tier. More specifically, the proposed rule 
change removes such tier, as the Exchange would rather redirect future 
resources and funding into other programs and tiers intended to 
incentivize increased order flow.
---------------------------------------------------------------------------

    \16\ As set forth on the Fee Schedule, ``ADV'' means average 
daily volume calculated as the number of shares added or removed, 
combined, per day, which is calculated on a monthly basis.
    \17\ As set forth on the Fee Schedule, ``Remove ADV'' means ADV 
with respect to orders that remove liquidity.
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes that the proposed rule change is consistent 
with the provisions of Section 6 of the Act,\18\ in general, and with 
Sections 6(b)(4) and 6(b)(5) of the Act,\19\ in particular, in that it 
provides for the equitable allocation of reasonable dues, fees and 
other charges among its Members and other persons using its facilities 
and is not designed to permit unfair discrimination between customers, 
issuers, brokers, or dealers.

    \18\ 15 U.S.C. 78f.
    \19\ 15 U.S.C. 78f(b)(4) and (5).
---------------------------------------------------------------------------

    As discussed above, the Exchange operates in a highly fragmented 
and 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 or incentives to be insufficient, and the 
Exchange represents only a small percentage of the overall market. The 
Commission and the courts have repeatedly expressed their preference 
for competition over regulatory intervention in determining prices, 
products, and services in the securities markets. In Regulation NMS, 
the Commission highlighted the importance of market forces in 
determining prices and SRO revenues and also recognized that current 
regulation of the market system ``has been remarkably successful in 
promoting market competition in its broader forms that are most 
important to investors and listed companies.'' \20\
---------------------------------------------------------------------------

    \20\ Securities Exchange Act Release No. 51808 (June 9, 2005), 
70 FR 37496, 37499 (June 29, 2005).
---------------------------------------------------------------------------

    The Exchange believes that the ever-shifting market share among the 
exchanges from month to month demonstrates that market participants can 
shift order flow or discontinue use of certain categories of products, 
in response to new or different pricing structures being introduced 
into the market. Accordingly, competitive forces constrain the 
Exchange's transaction fees and rebates, and market participants can 
readily trade on competing venues if they deem pricing levels at those 
other venues to be more favorable. The Exchange believes the proposal 
reflects a reasonable and competitive pricing structure designed to 
incentivize market participants to direct additional order flow, 
including displayed, non-displayed, liquidity-adding and/or NBBO 
setting orders, to the Exchange, which the Exchange believes would 
promote price discovery and enhance liquidity and market quality on the 
Exchange to the benefit of all Members and market participants.
    The Exchange notes that volume and quoting-based incentives (such 
as tiers) have been widely adopted by exchanges, including the 
Exchange, and are reasonable, equitable and not unfairly discriminatory 
because they are open to all members on an equal basis and provide 
additional benefits that are reasonably related to the value to an 
exchange's market quality associated with higher levels of market 
activity, such as higher levels of liquidity provision and/or growth 
patterns, and the introduction of higher volumes of orders into the 
price and volume discovery process. The Exchange believes that the 
Liquidity Provision Tier 1, as modified by the proposed change to the 
rebate under such tier, the Non-Display Add Tier 2, as modified by the 
proposed change to the required

[[Page 21097]]

criteria under such tier, and DLI Tier 1, as modified by the proposed 
change to the rebate provided under such tier, are reasonable, 
equitable and not unfairly discriminatory for these same reasons, as 
such tiers would provide Members with an incremental incentive to 
achieve certain volume thresholds on the Exchange, are available to all 
Members on an equal basis, and, as described above, are designed to 
encourage Members to maintain or increase their order flow, including 
in the form of displayed, non-displayed, liquidity-adding and/or NBBO 
setting orders, to the Exchange in order to qualify for an enhanced 
rebate for executions of Added Displayed Volume or Added Non-Displayed 
Volume, as applicable, thereby contributing to a deeper, more liquid 
and well balanced market ecosystem on the Exchange to the benefit of 
all Members and market participants. The Exchange also believes that 
such tiers reflect a reasonable and equitable allocation of fees and 
rebates, as the Exchange believes that the enhanced rebate for 
executions of Added Displayed Volume under the proposed modified 
Liquidity Provision Tier 1 and DLI Tier 1, as well as the enhanced 
rebate for executions of Non-Displayed volume under the proposed 
modified Non-Display Add Tier 2, each remains commensurate with the 
corresponding required criteria under each such tier and is reasonably 
related to the market quality benefits that each such tier is designed 
to achieve, as described above.
    The Exchange believes the proposed rule change to eliminate the 
Liquidity Removal Tier is reasonable because the Exchange is not 
required to maintain such an incentive. The Exchange believes the 
proposal to eliminate such tier is also equitable and not unfairly 
discriminatory because it applies equally to all Members (i.e., the 
tier will not be available for any Member). As noted above, the reduced 
fee offered under this tier is not affecting Members' behavior in that 
there are lower-than-expected levels of participation, and as such, the 
Exchange does not believe the proposed elimination of such tier will 
have a significant impact on any Member's trading behavior on the 
Exchange. Furthermore, the proposed rule change to eliminate the 
Liquidity Removal Tier enables the Exchange to redirect resources and 
funding into other pricing incentives and tiers intended to incentivize 
increased order flow and enhance market quality for all Members.
    For the reasons discussed above, the Exchange submits that the 
proposal satisfies the requirements of Sections 6(b)(4) and 6(b)(5) of 
the Act \21\ in that it provides for the equitable allocation of 
reasonable dues, fees and other charges among its Members and other 
persons using its facilities and is not designed to unfairly 
discriminate between customers, issuers, brokers, or dealers. As 
described more fully below in the Exchange's statement regarding the 
burden on competition, the Exchange believes that its transaction 
pricing is subject to significant competitive forces, and that the 
proposed additive rebate described herein is appropriate to address 
such forces.

    \21\ 15 U.S.C. 78f(b)(4) and (5).
---------------------------------------------------------------------------

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

    The Exchange does not believe that the proposal will result in any 
burden on competition that is not necessary or appropriate in 
furtherance of the purposes of the Act. Instead, as discussed above, 
the proposal is intended to incentivize market participants to direct 
additional order flow to the Exchange, thereby enhancing liquidity and 
market quality on the Exchange to the benefit of all Members and market 
participants. As a result, the Exchange believes the proposal would 
enhance its competitiveness as a market that attracts actionable 
orders, thereby making it a more desirable destination venue for its 
customers. For these reasons, the Exchange believes that the proposal 
furthers the Commission's goal in adopting Regulation NMS of fostering 
competition among orders, which promotes ``more efficient pricing of 
individual stocks for all types of orders, large and small.'' \22\
---------------------------------------------------------------------------

    \22\ See supra note 20.
---------------------------------------------------------------------------

Intramarket Competition
    As discussed above, the Exchange believes that the proposal would 
maintain a tiered pricing structure that is still consistent with the 
Exchange's overall pricing philosophy of encouraging added, displayed 
and/or non-displayed liquidity and would incentivize market 
participants to direct additional order flow to the Exchange through 
volume-based tiers, thereby enhancing liquidity and market quality on 
the Exchange to the benefit of all Members, as well as enhancing the 
attractiveness of the Exchange as a trading venue, which the Exchange 
believes, in turn, would continue to encourage market participants to 
direct additional order flow to the Exchange. Greater liquidity 
benefits all Members by providing more trading opportunities and 
encourages Members to send additional orders to the Exchange, thereby 
contributing to robust levels of liquidity, which benefits all market 
participants.
    The Exchange does not believe that the proposed changes would 
impose any burden on intramarket competition because such changes will 
incentivize members to submit additional order flow, thereby 
contributing to a more robust and well-balanced market ecosystem on the 
Exchange to the benefit of all Members as well as enhancing the 
attractiveness of the Exchange as a trading venue, which the Exchange 
believes, in turn, would continue to encourage market participants to 
direct additional order flow to the Exchange. The opportunity to 
qualify for the modified Liquidity Provision Tier 1, Non-Display Add 
Tier 2 and DLI Tier 1, and thus receive the corresponding enhanced 
rebates for executions of Added Displayed Volume or Added Non-Displayed 
Volume, as applicable, would be available to all Members that meet the 
associated volume requirements in any month. As described above, the 
Exchange believes that the required criteria under each such tier are 
commensurate with the corresponding rebate under such tier and are 
reasonably related to the enhanced liquidity and market quality that 
such tier is designed to promote. The Exchange does not believe that 
the proposed change to eliminate the Liquidity Removal Tier would 
impose any burden on intramarket competition because such changes will 
apply to all Members uniformly, as in, such incentive will no longer be 
available to any Member, and as described above, the Exchange does not 
believe the proposed elimination of such tier will have a significant 
impact on any Member's trading behavior on the Exchange. For the 
foregoing reasons, the Exchange believes the proposed changes would not 
impose any burden on intramarket competition that is not necessary or 
appropriate in furtherance of the purposes of the Act.
Intermarket Competition
    As noted 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 or incentives to be insufficient. Members have numerous 
alternative venues that they may participate on and direct their order 
flow to, including 17 other equities exchanges and numerous alternative 
trading systems and other off-exchange venues. As noted above, no 
single registered equities exchange

[[Page 21098]]

currently has more than approximately 14.1% of the total market share 
of executed volume of equities trading. Thus, in such a low-
concentrated and highly competitive market, no single equities exchange 
possesses significant pricing power in the execution of order flow. 
Moreover, the Exchange believes that the ever-shifting market share 
among the exchanges from month to month demonstrates that market 
participants can shift order flow or discontinue to reduce use of 
certain categories of products, in response to new or different pricing 
structures being introduced into the market. Accordingly, competitive 
forces constrain the Exchange's transaction fees and rebates, including 
with respect to executions of Added Displayed Volume and Added Non-
Displayed Volume, and market participants can readily choose to send 
their orders to other exchange and off-exchange venues if they deem fee 
levels at those other venues to be more favorable. As described above, 
the proposed change is a competitive proposal through which the 
Exchange is seeking to generate additional revenue with respect to its 
transaction pricing and to encourage the submission of additional order 
flow to the Exchange through volume-based tiers which have been widely 
adopted by exchanges, including the Exchange. Accordingly, the Exchange 
believes the proposal would not burden, but rather promote, intermarket 
competition by enabling it to better compete with other exchanges that 
offer similar incentives to market participants that enhance market 
quality and/or achieve certain quoting requirements.
    Additionally, the Commission has repeatedly expressed its 
preference for competition over regulatory intervention in determining 
prices, products, and services in the securities markets. Specifically, 
in Regulation NMS, the Commission highlighted the importance of market 
forces in determining prices and SRO revenues and, also, recognized 
that current regulation of the market system ``has been remarkably 
successful in promoting market competition in its broader forms that 
are most important to investors and listed companies.'' \23\ The fact 
that this market is competitive has also long been recognized by the 
courts. In NetCoalition v. SEC, the D.C. Circuit stated as follows: 
``[n]o one disputes that competition for order flow is `fierce.' . . . 
As the SEC explained, `[i]n the U.S. national market system, buyers and 
sellers of securities, and the broker-dealers that act as their order-
routing agents, have a wide range of choices of where to route orders 
for execution'; [and] `no exchange can afford to take its market share 
percentages for granted' because `no exchange possesses a monopoly, 
regulatory or otherwise, in the execution of order flow from broker 
dealers'. . . .''.\24\ Accordingly, the Exchange does not believe its 
proposed pricing changes impose any burden on competition that is not 
necessary or appropriate in furtherance of the purposes of the Act.

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
