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
    MRX proposes to increase its ORF from $0.0004 to $0.0010 per 
contract

[[Page 20540]]

side effective May 1, 2025. The increased ORF rate will sunset on 
December 31, 2025 and will revert to $0.0004 per contract side. 
Additionally, the Exchange proposes to discontinue the ORF model 
scheduled to be implemented in June 2025.\4\
---------------------------------------------------------------------------

    \4\ Id.
---------------------------------------------------------------------------

Background on Current ORF
    Today, MRX assesses its ORF for each Customer \5\ option 
transaction that is either: (1) executed by a Member \6\ on MRX; or (2) 
cleared by an MRX Member at OCC in the Customer range,\7\ even if the 
transaction was executed by a non-Member of MRX, regardless of the 
exchange on which the transaction occurs.\8\ If the OCC clearing member 
is an MRX Member, ORF is assessed and collected on all ultimately 
cleared Customer contracts (after adjustment for CMTA \9\); and (2) if 
the OCC clearing member is not an MRX Member, ORF is collected only on 
the cleared Customer contracts executed at MRX, taking into account any 
CMTA instructions which may result in collecting the ORF from a non-
Member.\10\ The current MRX ORF is $0.0004 per contract side.
---------------------------------------------------------------------------

    \5\ Today, ORF is collected from Customers, Professionals and 
broker-dealers that are not affiliated with a clearing member that 
clear in the ``C'' range at OCC.
    \6\ The term ``Member'' means an organization that has been 
approved to exercise trading rights associated with Exchange Rights. 
See General 1, Section 1(a)(14).
    \7\ Market participants must record the appropriate account 
origin code on all orders at the time of entry of the order. The 
Exchange represents that it has surveillances in place to verify 
that members mark orders with the correct account origin code.
    \8\ The Exchange uses reports from OCC when assessing and 
collecting the ORF.
    \9\ CMTA or Clearing Member Trade Assignment is a form of 
``give-up'' whereby the position will be assigned to a specific 
clearing firm at OCC.
    \10\ By way of example, if Broker A, an MRX Member, routes a 
Customer order to CBOE and the transaction executes on CBOE and 
clears in Broker A's OCC Clearing account, ORF will be collected by 
MRX from Broker A's clearing account at OCC via direct debit. While 
this transaction was executed on a market other than MRX, it was 
cleared by an MRX Member in the member's OCC clearing account in the 
Customer range, therefore there is a regulatory nexus between MRX 
and the transaction. If Broker A was not an MRX Member, then no ORF 
should be assessed and collected because there is no nexus; the 
transaction did not execute on MRX nor was it cleared by an MRX 
Member.
---------------------------------------------------------------------------

    Today, in the case where a Member both executes a transaction and 
clears the transaction, the ORF will be assessed to and collected from 
that Member. Today, in the case where a Member executes a transaction 
and a different Member clears the transaction, the ORF will be assessed 
to and collected from the Member who clears the transaction and not the 
Member who executes the transaction. Today, in the case where a non-
Member executes a transaction at an away market and a Member clears the 
transaction, the ORF will be assessed to and collected from the Member 
who clears the transaction. Today, in the case where a Member executes 
a transaction on MRX and a non-Member clears the transaction, the ORF 
will be assessed to the Member that executed the transaction on MRX and 
collected from the non-Member who cleared the transaction. Today, in 
the case where a Member executes a transaction at an away market and a 
non-Member ultimately clears the transaction, the ORF will not be 
assessed to the Member who executed the transaction or collected from 
the non-Member who cleared the transaction because the Exchange does 
not have access to the data to make absolutely certain that ORF should 
apply. Further, the data does not allow the Exchange to identify the 
Member executing the trade at an away market.
ORF Revenue and Monitoring of ORF
    Today, the Exchange monitors the amount of revenue collected from 
the ORF (``ORF Regulatory Revenue'') to ensure that it, in combination 
with other regulatory fees and fines, does not exceed Options 
Regulatory Costs.\11\ In determining whether an expense is considered 
an Options Regulatory Cost, the Exchange reviews all costs and makes 
determinations if there is a nexus between the expense and a regulatory 
function. The Exchange notes that fines collected by the Exchange in 
connection with a disciplinary matter offset Options Regulatory Cost.
---------------------------------------------------------------------------

    \11\ The regulatory costs for options comprise a subset of the 
Exchange's regulatory budget that is specifically related to options 
regulatory expenses and encompasses the cost to regulate all 
Members' options activity (``Options Regulatory Cost'').
---------------------------------------------------------------------------

    ORF Regulatory Revenue, when combined with all of the Exchange's 
other regulatory fees and fines, is designed to recover the Options 
Regulatory Costs to the Exchange of the supervision and regulation of 
member Customer options business including performing routine 
surveillances, investigations, examinations, financial monitoring, and 
policy, rulemaking, interpretive, and enforcement activities. Options 
Regulatory Costs include direct regulatory expenses and certain 
indirect expenses in support of the regulatory function. The direct 
expenses include in-house and third-party service provider costs to 
support the day-to-day regulatory work such as surveillances, 
investigations and examinations. The indirect expenses are only those 
expenses that are in support of the regulatory functions, such areas 
include Office of the General Counsel, technology, finance, and 
internal audit. Indirect expenses will not exceed 35% of the total 
Options Regulatory Costs, in which case direct expenses could be 65% or 
more of total Options Regulatory Costs.\12\
---------------------------------------------------------------------------

    \12\ Direct and indirect expenses are based on the Exchange's 
2025 Regulatory Budget.
---------------------------------------------------------------------------

Proposal for May 1, 2025
    At this time, the Exchange proposes to increase MRX's ORF from 
$0.0004 to $0.0010 per contract side effective May 1, 2025. For several 
years, MRX has not been collecting ORF Regulatory Revenue at levels 
that cover a material portion of its Options Regulatory Cost. By way of 
background, initially MRX did not adopt an ORF as a new options market. 
Despite the fact that MRX was operating its options market since 2016, 
it did not establish an ORF until February 1, 2019. The initial ORF 
rate was set at $0.0004 per contract side and has remined the same to 
date. In 2024, MRX proposed to revamp the current process of assessing 
and collecting its ORF \13\ along with other Nasdaq affiliated 
exchanges in an attempt to reform ORF. MRX's current ORF rate has been 
in effect for over 6 years. The Exchange notified Members of the 
proposed adjustment to the ORF through an Options Trader Alert.\14\ For 
several years MRX has been under collecting ORF and proposes to 
temporarily increase the amount of ORF that will be collected by the 
Exchange from $0.0004 to $0.0010 per contract side. The Exchange 
proposes the ORF of $0.0010 per contract side to have an automatic 
sunset on December 31, 2025. The proposed increase is based on the 
Exchange's estimated projections for of its Options Regulatory Cost as 
well as the projected ORF Regulatory Revenue, when combined with all of 
the Exchange's other regulatory fees and fines. The Exchange will 
continue to monitor the amount of ORF Regulatory Revenue collected from 
the ORF to ensure that ORF Regulatory Revenue, in combination with its 
other regulatory fees and fines, does not exceed Options Regulatory 
Costs. If the Exchange determines that to be the case, the

[[Page 20541]]

Exchange will adjust the ORF by submitting a fee change filing to the 
Commission and notifying \15\ its Members via an Options Trader 
Alert.\16\

    \15\ The Exchange will provide Members with such notice at least 
30 calendar days prior to the effective date of the change.

it provided the Commission confidential details regarding the 
Exchange's projected regulatory revenue, including projected revenue 
from ORF, along with a projected regulatory expense.
---------------------------------------------------------------------------

Future Proposals
    MRX previously filed a proposed amendment to its ORF, effective as 
of January 1, 2025,\17\ to amend its methodology of collection to: (1) 
exclude options transactions in proprietary products; and (2) assess 
ORF in all clearing ranges except market makers who clear as ``M'' at 
OCC. Additionally, MRX proposed to assess a different rate for trades 
executed on MRX (``Local ORF Rate'') and trades executed on non-MRX 
exchanges (``Away ORF Rate'').\18\ The Exchange also filed to delay the 
implementation of SR-MRX-2024-45, with respect to the new ORF and 
methodology therein which was effective on January 1, 2025, so that it 
would now be implemented on June 1, 2025.\19\ At this time, the 
Exchange proposes to discontinue its June 2025 ORF.\20\ The Exchange 
received feedback from the Members \21\ and SIFMA \22\ related to the 
implementation of its June 2025 ORF. In particular, two fields 
necessary for information sharing of executing exchange information 
among Members and Clearing Members will not be available after an 
upcoming technology migration at OCC.\23\ In light of this information, 
the Exchange has been re-evaluating its ORF model and plans to revamp 
the current process of assessing and collecting ORF, which would be 
subject to, and described further in, a future rule filing. 
Particularly, the Exchange is exploring proposing a modified ORF model 
in which ORF would only be assessed to on-exchange transactions and 
would continue to be assessed only to customers. At this this time, the 
Exchange expects to continue assessing ORF as it does today and will 
continue to ensure that ORF Regulatory Revenue, in combination with its 
other regulatory fees and fines, does not exceed Options Regulatory 
Cost.

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

    To create real ORF reform, moving to a new ORF model that only 
assesses a fee to transactions that occur on the Exchange would remove 
any duplicative ORF billing. The Exchange believes that each exchange 
should likewise adopt a similar model to ensure consistent industry 
billing of ORF to the benefit of market participants. A consistent 
methodology of assessing and collecting ORF will also remove confusion 
and complexity in the billing of ORF. The Exchange has been engaged in 
remodeling its current ORF over the last year and has held many 
conversations with market participants to establish a framework that is 
practical and fair. The Exchange remains committed to ORF reform and 
will continue to evaluate its ORF model and seek feedback from market 
participants. Until such time as the new ORF model is in place, the 
Exchange believes that it is fair and reasonable to temporarily raise 
the current rate under the existing ORF model to allow MRX to increase 
its current collection to offset Options Regulatory Costs to maintain 
its regulatory budget
    In light of the Exchange's anticipated proposal to revamp ORF, the 
Exchange also proposes to adopt a sunset date of December 31, 2025 for 
the current proposed rate of $0.0010 per contract side, at which point 
the Exchange would revert back to current ORF rate of $0.0004 per 
contract side. The proposed sunset date will provide time for the 
Exchange to discuss its anticipated, or potential alternative, ORF 
model with market participants towards establishment of one new, 
unified model going forward. The Exchange will endeavor however to 
implement the modified ORF structure noted above prior to the proposed 
December 31, 2025 sunset date (i.e., the existence of the sunset date 
of December 31, 2025 for the proposed ORF rate would not preclude the 
Exchange from filing to modify its ORF methodology and rate prior to 
that date).
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.\24\ Specifically, the 
Exchange believes the proposed rule change is consistent with Section 
6(b)(4) of the Act,\25\ which provides that Exchange rules may provide 
for the equitable allocation of reasonable dues, fees, and other 
charges among its members, and other persons using its facilities. 
Additionally, the Exchange believes the proposed rule change is 
consistent with the Section 6(b)(5) \26\ requirement that the rules of 
an exchange not be designed to permit unfair discrimination between 
customers, issuers, brokers, or dealers.
---------------------------------------------------------------------------

    \24\ 15 U.S.C. 78f(b).
    \25\ 15 U.S.C. 78f(b)(4).
    \26\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    The Exchange believes the proposed pricing change is reasonable 
because it would help ensure that ORF Regulatory Revenue, in 
combination with other regulatory fees and fines, would help offset, 
but not exceed, Options Regulatory Cost. As discussed, the Exchange has 
designed the ORF to generate ORF Regulatory Revenue that would be less 
than Options Regulatory Cost, which is consistent with the practice 
across the options industry and the view of the Commission that 
regulatory fees be used for regulatory purposes and not to support the 
Exchange's business side. The Exchange has determined to increase its 
ORF because it has been under collecting for a few years. Initially, 
MRX did not adopt an ORF as a new market in 2016. MRX adopted its ORF 
on February 1, 2019 at a rate of $0.0004 per contract side. Thereafter, 
the Exchange did not amend its ORF until 2024 when it proposed to 
revamp the current process of assessing and collecting ORF.\27\ Today, 
MRX's ORF remains at the 2019 rate. The proposed increase is reasonable 
as it would offset the anticipated Options Regulatory Cost in line with 
other options exchanges that are collecting at a higher rate and some 
new options markets which collected ORF from the first day of trading, 
while still not exceeding a material portion of Options Regulatory 
Cost. As noted above, the Exchange will also continue to monitor on a 
monthly basis so that ORF Regulatory Revenue, in combination with its 
other regulatory fees and fines, does not exceed Options

[[Page 20542]]

Regulatory Cost. If the Exchange determines ORF Regulatory Revenue 
would exceed a material portion of Options Regulatory Cost, the 
Exchange will reduce the ORF by submitting a pricing change filing to 
the Commission.
---------------------------------------------------------------------------

    \27\ See Securities Exchange Act Release No. 101891 (December 
12, 2024), 89 FR 103017 (December 18, 2024) (SR-MRX-2024-45) (Notice 
of Filing and Immediate Effectiveness of Proposed Rule Change To 
Adopt a New Approach to the Options Regulatory Fee (ORF) in 2025).
---------------------------------------------------------------------------

    The Exchange also believes the proposed fee change is equitable and 
not unfairly discriminatory in that it is charged to all Members on all 
their transactions that clear in the customer range at the OCC. The 
Exchange believes the ORF ensures fairness by assessing higher fees to 
those Members that require more Exchange regulatory services based on 
the amount of customer options business they conduct. Regulating 
customer trading activity is much more labor intensive and requires 
greater expenditure of human and technical resources than regulating 
non-customer trading activity, which tends to be more automated and 
less labor-intensive. For example, there are costs associated with main 
office and branch office examinations (e.g., staff and travel 
expenses), as well as investigations into customer complaints and the 
terminations of registered persons. As a result, the costs associated 
with administering the customer component of the Exchange's overall 
regulatory program are materially higher than the costs associated with 
administering the non-customer component (e.g., proprietary 
transactions) of its regulatory program. Moreover, the Exchange notes 
that it has broad regulatory responsibilities with respect to its 
Members' activities, irrespective of where their transactions take 
place. Many of the Exchange's surveillance programs for customer 
trading activity may require the Exchange to look at activity across 
all markets, such as reviews related to position limit violations and 
manipulation. Indeed, the Exchange cannot effectively review for such 
conduct without looking at and evaluating activity regardless of where 
it transpires. In addition to its own surveillance programs, the 
Exchange also works with other exchanges on intermarket surveillance 
related issues. Through its participation in the Intermarket 
Surveillance Group (``ISG'') \28\ the Exchange shares information and 
coordinates inquiries and investigations with other exchanges designed 
to address potential intermarket manipulation and trading abuses. 
Accordingly, there is a strong nexus between the ORF and the Exchange's 
regulatory activities with respect to its Members' customer trading 
activity.
---------------------------------------------------------------------------

    \28\ ISG is an industry organization formed in 1983 to 
coordinate intermarket surveillance among the self-regulatory 
organizations by cooperatively sharing regulatory information 
pursuant to a written agreement between the parties. The goal of the 
ISG's information sharing is to coordinate regulatory efforts to 
address potential intermarket trading abuses and manipulations.
---------------------------------------------------------------------------

    The Exchange's proposal to discontinue its June 2025 ORF is 
reasonable because it has come to light that certain information 
necessary for billing of ORF would not be available later in 2025. In 
light of this information, the Exchange has been re-evaluating its ORF 
model and plans to revamp the current process of assessing and 
collecting ORF, which would be subject to, and described further in, a 
future rule filing. Particularly, the Exchange anticipates moving to a 
modified ORF model in which ORF would only be assessed to on-exchange 
transactions and would continue to be assessed only to customers. At 
this this time, the Exchange expects to continue assessing ORF as it 
does today and will continue to ensure that ORF Regulatory Revenue, in 
combination with its other regulatory fees and fines, does not exceed 
Options Regulatory Cost. Until such time as the new ORF model is in 
place, the Exchange believes that it is fair and reasonable to 
temporarily raise the current rate under the existing ORF model to 
allow MRX to increase its current collection to offset Options 
Regulatory Costs to maintain its regulatory budget.
    The Exchange's proposal to discontinue its June 2025 ORF is 
equitable and not unfairly discriminatory as the proposal would not 
apply to any Member.

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 not necessary or appropriate in 
furtherance of the purposes of the Act. This proposal does not create 
an unnecessary or inappropriate intra-market burden on competition 
because ORF applies to all customer activity, thereby raising ORF 
Regulatory Revenue to offset Options Regulatory Cost. It also 
supplements the regulatory revenue derived from non-customer activity. 
The Exchange notes, however, the proposed change is not designed to 
address any competitive issues. Indeed, this proposal does not create 
an unnecessary or inappropriate inter-market burden on competition 
because it is a regulatory fee that supports regulation in furtherance 
of the purposes of the Act. The Exchange is obligated to ensure that 
the amount of ORF Regulatory Revenue collected from the ORF, in 
combination with its other regulatory fees and fines, does not exceed 
Options Regulatory Cost.
    Further, no Member would be subject to the June 2025 ORF as a 
result of this proposal.

C. Self-Regulatory Organization's Statement on Comments on the Proposed 
Rule Change Received From Members, Participants, or Others

    No written comments were either solicited or received.

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

    The foregoing rule change has become effective pursuant to Section 
19(b)(3)(A) of the Act \29\ and paragraph (f)(2) of Rule 19b-4 \30\ 
thereunder.

    \30\ 17 CFR 240.19b-4(f)(2).
---------------------------------------------------------------------------

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