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

    The Exchange proposes to amend the Fee Schedule. Specifically, the 
Exchange proposes to amend Section III.B. (Port Fees) to propose a 
limit on the number of SAIL Order Entry Ports that a Participant may be 
credentialed to use in a month and add language clarifying that the 
Exchange currently offers two types of SAIL Ports. The Exchange is also 
proposing to make certain technical and non-substantive changes within 
the Fee Schedule. The text of the proposed rule change is available 
from the principal office of the Exchange, and also on the Exchange's 
internet website at <a href="https://rules.boxexchange.com/rulefilings">https://rules.boxexchange.com/rulefilings</a>.

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 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.

[[Page 58229]]

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

1. Purpose
    The Exchange proposes to amend Section III.B. (Port Fees) of the 
Fee Schedule. Specifically, the Exchange proposes to amend Section 
III.B.2. (SAIL) of the Fee Schedule to propose a limit on the number of 
SAIL Order Entry Ports that a Participant may be credentialed to use in 
a month. The Exchange notes that the proposed limitation is similar to 
an existing limitation in place at another options exchange.\3\ The 
Exchange is also proposing to add language to Section III.B.2. 
clarifying that the Exchange currently offers two types of SAIL Ports--
Order Entry and Market Making.
---------------------------------------------------------------------------

    \3\ See Nasdaq Stock Market LLC (``Nasdaq'') Options 7, Section 
3(i)(2) SQF Port Fee.
---------------------------------------------------------------------------

    Currently, BOX assesses monthly SOLA[supreg] Access Information 
Language (``SAIL'') Port \4\ Fees on all Participants in each month a 
Participant is credentialed to use a SAIL Port in the production 
environment and based upon the number of credentialed SAIL Ports. 
Participants are assessed a SAIL Order Entry Port fee of $540 per month 
per port for the first five ports (1-5) and $162 per month for each 
additional port.
---------------------------------------------------------------------------

    \4\ SAIL Market Making Ports are connections to BOX systems that 
enable Market Makers to continuously quote on BOX, while SAIL Order 
Entry Ports allow Market Makers and other Participants to submit 
order flow to BOX.
---------------------------------------------------------------------------

    At this time, the Exchange proposes to limit a Participant to no 
more than 200 SAIL Order Entry Ports per month.\5\ The Exchange notes 
that in order to submit orders Participants must connect to a minimum 
of one port via FIX or SAIL.\6\ While a Participant may elect to obtain 
multiple SAIL Order Entry Ports for business purposes, in order to 
submit orders a Participant is only required to connect to one port and 
can choose between either FIX or SAIL Ports. The Exchange utilizes 
ports as a secure method for Participants to submit orders and quotes 
into the Trading System and for the Exchange to send messages related 
to those orders and quotes to Participants. In order to properly 
regulate its Participants and secure the trading environment, the 
Exchange has taken measures to ensure access is monitored and 
maintained with various controls. The Exchange believes that adopting 
such limit will help to govern connectivity management and accommodate 
overall demand on the Exchange by providing a means to efficiently 
deploy Exchange resources, as no exchange has infinite capacity. In the 
event a Participant were to reach the proposed limit of 200 SAIL Order 
Entry Ports, such Participant would have the option to be credentialed 
for additional FIX Ports for order entry. The Exchange notes that, 
generally, there are no current limitations on the number of FIX Ports 
that a Participant may be credentialed for per month. Accordingly, the 
Exchange believes a limit of 200 SAIL Order Entry Ports will provide it 
with the appropriate bandwidth to support future growth and new 
Participant entrants.\7\ The Exchange will announce by Notice when it 
will implement the 200 SAIL Order Entry Ports per month limit.
---------------------------------------------------------------------------

    \5\ The Exchange will also issue a Notice to announce the 
limitation to Participants.
    \6\ SAIL is the native protocol for SOLA[supreg], which offers 
functionalities required by both Order Flow Providers and Market 
Makers on BOX. SAIL is a proprietary protocol of BOX and allows 
Participants to connect, send, and receive messages related to 
orders and quotes. SAIL Ports offer lower latency as compared to 
Financial Information eXchange (``FIX'') Ports, which may be 
attractive to Participants depending on their trading behavior. 
Alternatively, FIX is an order management protocol widely used by 
professional trading systems and many order management systems. BOX 
provides a FIX interface that allows Participants, who are already 
using the FIX protocol for order routing and management to other 
options markets, a streamlined way to connect to the BOX Trading 
System.
    \7\ The Exchange will periodically review the SAIL Order Entry 
Port limit. If the Exchange elects to amend the limit in the future, 
it will file a rule proposal with the Commission.
---------------------------------------------------------------------------

    Finally, the Exchange is proposing to make a few technical edits to 
the Fee Schedule. Specifically, the Exchange proposes to amend Section 
II. C. (Options Regulatory Fee) to remove obsolete text regarding an 
ORF rate that is no longer in effect, to amend III. (Technology Fees) 
to add the word ``Section'' to the heading for consistency with the 
other section headings within the Fee Schedule, to correct an internal 
cross reference within current endnote 36, and to renumber certain 
endnotes within the Fee Schedule to conform with the changes proposed 
herein.
2. Statutory Basis
    The Exchange believes that the proposal is consistent with the 
requirements of Section 6(b) of the Act,\8\ in general, and Section 
6(b)(5) of the Act,\9\ in particular, in that it is designed to promote 
just and equitable principles of trade, 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.
---------------------------------------------------------------------------

    \8\ 15 U.S.C. 78f(b).
    \9\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    The Exchange's proposal to limit a Participant to no more than 200 
SAIL Order Entry Ports per month is consistent with the Act because it 
will allow the Exchange to ensure rational and efficient use of 
resources in its overall connectivity management. Additionally, the 
Exchange believes that the proposed rule change will further the 
purposes of the Act by providing an additional means to the Exchange 
for managing its finite resources, as no exchange has unlimited 
capacity. The proposed limit on SAIL Order Entry Ports is being 
proposed in order to manage capacity and resources is designed to 
assist with the maintenance of a fair and orderly market, promote just 
and equitable principles of trade, and prevent fraudulent and 
manipulative acts and practices, as it ensures that the Exchange is 
utilizing its resources in an effective and efficient manner.
    The Exchange utilizes ports as a secure method for Participants to 
submit orders and quotes into the Trading System and for the Exchange 
to send messages related to those orders and quotes to Participants. 
Only approved Participants may utilize a SAIL Order Entry Port. Once 
approved, Participants may be credentialed to use SAIL Order Entry 
Ports to submit orders into the Exchange. While a Participant may elect 
to obtain multiple SAIL Order Entry Ports for business purposes, in 
order to submit orders a Participant is only required to connect to one 
port and can choose between either FIX or SAIL. In the event a 
Participant were to reach the proposed limit of 200 SAIL Order Entry 
Ports, such Participant would have the option to be credentialed for 
additional FIX Ports for order entry. The Exchange notes that, 
generally, there are no current limitations on the number of FIX Ports 
that a Participant may be credentialed for per month. In order to 
properly regulate its Participants and secure the trading environment, 
the Exchange has taken measures to ensure access is monitored and 
maintained with various controls that will protect investors and the 
public interest. Specifically, the Exchange ensures that information 
security safeguards, upgrades, and general port management are in 
effect for all SAIL Order Entry Ports regardless of whether the SAIL 
Order Entry Port is actively in use. As a result of these efforts, the 
Exchange incurs costs to manage and maintain its SAIL Order Entry Ports 
and the secure environment surrounding its platform.
    The Exchange's proposal is intended to assist the Exchange in 
continuing to govern its connectivity management in a reasonable manner 
while protecting investors and the general public by encouraging the 
efficient and effective use of the Exchange's resources with the

[[Page 58230]]

limit on SAIL Order Entry Ports. The Exchange believes that its 
proposal is consistent with the Act in that it will provide the 
Exchange the ability to maintain the appropriate bandwidth to support 
future growth and new entrants thereby removing impediments to and 
perfect the mechanism of a free and open market.
    The Exchange believes further that adding language to Section 
III.B.2. clarifying that the Exchange currently offers two types of 
SAIL Ports, Order Entry and Market Making, is consistent with the Act 
because the proposed change will provide greater clarity to market 
participants regarding the Exchange's Fee Schedule. The Exchange 
believes that this additional detail relating to its current SAIL Port 
offerings will reduce the potential for investor confusion and make its 
existing fees more clear.
    Finally, the Exchange proposes to remove obsolete text regarding an 
ORF rate that is no longer in effect, to add the word ``Section'' to 
existing section heading III. (Technology Fees) for consistency with 
the other section headings within the Fee Schedule, to correct an 
internal cross reference within current endnote 36, and to renumber 
certain endnotes within the Fee Schedule to conform with the changes 
proposed herein. The Exchange believes that these proposed technical 
and non-substantive changes will promote just and equitable principles 
of trade and remove impediments to and perfect the mechanism of a free 
and open market and a national market system because the proposed 
change will provide greater clarity to market participants regarding 
the Exchange's Fee Schedule. It is in the public interest for the 
Exchange's Fee Schedule to be clear and accurate so as to eliminate the 
potential for confusion.

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

    The Exchange 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 proposed 
change is not intended to address competitive issues and instead is 
being proposed to assist with the maintenance of a fair and orderly 
market by providing the Exchange with the ability govern its 
connectivity management in a reasonable manner and to encourage the 
efficient and rational use of the Exchange's finite resources. The 
Exchange also notes that the proposed limit is similar to an existing 
limitation in place at another options exchange.\10\
---------------------------------------------------------------------------

    \10\ See supra note 3.
---------------------------------------------------------------------------

    Intramarket Competition. The Exchange believes the proposed rule 
change to amend Section III.B. (Port Fees) of the Fee Schedule to 
propose a limit on the number of SAIL Order Entry Ports that a 
Participant may be credentialed to use in a month, would not place an 
unfair burden on intramarket competition because it is designed to 
encourage the efficient use of the Exchange's resources and to provide 
the Exchange the ability to maintain the appropriate bandwidth to 
support future growth. The Exchange does not believe that its proposal 
will place any category of market participant at a competitive 
disadvantage because all Participants will uniformly be permitted to be 
credentialed to use no more than 200 SAIL Order Entry Ports in a month. 
Today, no Participant has exceeded 200 SAIL Order Entry Ports.
    Intermarket Competition. The Exchange believes the proposal would 
not place an unfair burden on intermarket competition as it is not 
intended to address any competitive issues but is instead designed 
solely to encourage the efficient use of the Exchange's resources and 
to allow the Exchange to continue to reasonably govern its connectivity 
management. The Exchange believes that the proposal to limit the number 
of SAIL Order Entry Ports that a Participant may be credentialed to use 
each month will help ensure that the Exchange has adequate tools at its 
disposal to maintain the appropriate bandwidth to support future growth 
and new entrants, which, in turn, will sustain the Exchange's overall 
competitiveness. The Exchange also notes that nothing prevents other 
options exchanges, as applicable, from electing to adopt a similar 
limit.\11\
---------------------------------------------------------------------------

    \11\ The Exchange notes that Nasdaq and Nasdaq PHLX LLC (PHLX'') 
currently prohibit Market Makers from subscribing to more than 250 
SQF Ports per month. See Nasdaq Options 7, Section 3(i)(2) SQF Port 
Fee and PHLX Options 7, Section 9(B)(i)(3), respectively.
---------------------------------------------------------------------------

    The Exchange also does not believe the proposed technical and 
clarifying changes will have any unnecessary or inappropriate burden on 
competition because these changes will apply equally to all 
Participants and are intended to provide greater clarity to market 
participants regarding the Exchange's Fee Schedule to reduce potential 
investor confusion.
    For the foregoing reasons, 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.

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

    The Exchange has neither solicited nor received comments on the 
proposed rule change.

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

    Because the foregoing proposed rule change does not: (i) 
significantly affect the protection of investors or the public 
interest; (ii) impose any significant burden on competition; and (iii) 
become operative for 30 days from the date on which it was filed, or 
such shorter time as the Commission may designate, it has become 
effective pursuant to Section 19(b)(3)(A) of the Act \12\ and Rule 19b-
4(f)(6) thereunder.\13\
---------------------------------------------------------------------------

    \12\ 15 U.S.C. 78s(b)(3)(A).
    \13\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6)(iii) 
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.
---------------------------------------------------------------------------

    A proposed rule change filed pursuant to Rule 19b-4(f)(6) under the 
Act \14\ normally does not become operative for 30 days after the date 
of its filing. However, Rule 19b-4(f)(6)(iii) \15\ permits the 
Commission to designate a shorter time if such action is consistent 
with the protection of investors and the public interest. The Exchange 
has requested that the Commission waive the 30-day operative delay so 
that the proposed rule change may become operative upon filing. The 
proposed limit is similar to an existing limitation in place at another 
options exchange \16\ and raises no new or novel issues. Accordingly, 
it is consistent with the protection of investors and the public 
interest to waive the 30-day operative delay.\17\
---------------------------------------------------------------------------

    \14\ 17 CFR 240.19b-4(f)(6).
    \15\ 17 CFR 240.19b-4(f)(6)(iii).
    \16\ See supra note 3.
    \17\ For purposes only of waiving the 30-day operative delay, 
the Commission has considered the proposed rule's impact on 
efficiency, competition, and capital formation. 15 U.S.C. 78c(f).
---------------------------------------------------------------------------

    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

[[Page 58231]]

Commission takes such action, the Commission shall institute 
proceedings to determine whether the proposed rule should be approved 
or disapproved.
