SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-82252; File No. SR-CHX-2017-08]

Self-Regulatory Organizations; Chicago Stock Exchange, Inc.; 
Notice of Filing of Amendment No. 2 to the Proposed Rule Change To 
Amend the Schedule of Fees and Assessments To Adopt a Fee Schedule To 
Establish Fees for Industry Members Related to the National Market 
System Plan Governing the Consolidated Audit Trail

December 8, 2017.
    On May 3, 2017, Chicago Stock Exchange, Inc. (``Exchange'' or 
``CHX'') filed with the Securities and Exchange Commission 
(``Commission''), pursuant to Section 19(b)(1) of the Securities 
Exchange Act of 1934 (``Act'') \1\ and Rule 19b-4 thereunder,\2\ a 
proposed rule change to adopt a fee schedule to establish the fees for 
Industry Members related to the National Market System Plan Governing 
the Consolidated Audit Trail (``CAT NMS Plan''). The proposed rule 
change was published in the Federal Register for comment on May 22, 
2017.\3\ The Commission received seven comment letters on the proposed 
rule change,\4\ and a response to comments from the CAT NMS Plan 
Participants.\5\ On June 30, 2017, the Commission temporarily suspended 
and initiated proceedings to determine whether to approve or disapprove 
the proposed rule change.\6\ The Commission thereafter received seven 
comment letters,\7\ and a response to comments from the 
Participants.\8\ On November 9, 2017, the Exchange filed Amendment No. 
1 to the proposed rule change.\9\ On November 9, 2017, the Commission 
extended the time period within which to approve the proposed rule 
change or disapprove the proposed rule change to January 14, 2018.\10\ 
On November 30, 2017, the Exchange filed Amendment No. 2 to the 
proposed rule change, as described in Items I and II below, which Items 
have been prepared by the Exchange. The Commission is publishing this 
notice to solicit comments from interested persons on Amendment No. 2.

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

    On May 3, 2017, the Chicago Stock Exchange, Inc. (``Exchange'' or 
``CHX'') filed with the Securities and Exchange Commission 
(``Commission'' or ``SEC'') proposed rule change SR-CHX-2017-08 (the 
``Original Proposal''), pursuant to which the Exchange proposed to 
adopt a fee schedule to establish the fees for Industry Members related 
to the National Market System Plan Governing the Consolidated Audit 
Trail (the ``CAT NMS Plan'' or ``Plan'').\11\ On November 9, 2017, the 
Exchange filed an amendment to the Original Proposal (``First 
Amendment''). The Exchange files this proposed rule change (the 
``Second Amendment'') to amend the Original Proposal as amended by the 
First Amendment.
---------------------------------------------------------------------------

    \11\ Unless otherwise specified, capitalized terms used in this 
fee filing are defined as set forth herein, the CAT Compliance Rule 
Series, in the CAT NMS Plan, or the Original Proposal.
---------------------------------------------------------------------------

    The text of this proposed rule change is available on the 
Exchange's website at (www.chx.com) and in the Commission's Public 
Reference Room.

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 CHX included statements 
concerning the purpose of and basis for the proposed rule changes 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 CHX has prepared summaries, set forth in sections A, 
B and C below, of the most significant aspects of such statements.

Market LLC, New York Stock Exchange LLC, NYSE American LLC,\14\ NYSE 
Arca, Inc. and NYSE National, Inc.\15\ (collectively, the ``Plan 
Participants'') \16\ filed with the Commission, pursuant to Section 11A 
of the Exchange Act \17\ and Rule 608 of Regulation NMS thereunder,\18\ 
the CAT NMS Plan.\19\ The Plan Participants filed the Plan to comply 
with Rule 613 of Regulation NMS under the Exchange Act. The Plan was 
published for comment in the Federal Register on May 17, 2016,\20\ and 
approved by the Commission, as modified, on November 15, 2016.\21\ The 
Plan is designed to create, implement and maintain a consolidated audit 
trail (``CAT'') that would capture customer and order event information 
for orders in NMS Securities and OTC Equity Securities, across all 
markets, from the time of order inception through routing, 
cancellation, modification, or execution in a single consolidated data 
source. The Plan accomplishes this by creating CAT NMS, LLC (the 
``Company''), of which each Plan Participant is a member, to operate 
the CAT.\22\ Under the CAT NMS Plan, the Operating Committee of the 
Company (``Operating Committee'') has discretion to establish funding 
for the Company to operate the CAT, including establishing fees that 
the Plan Participants will pay, and establishing fees for Industry 
Members that will be implemented by the Plan Participants (``CAT 
Fees'').\23\ The Plan Participants are required to file with the SEC 
under Section 19(b) of the Exchange Act any such CAT Fees applicable to 
Industry Members that the Operating Committee approves.\24\ 
Accordingly, the Exchange submitted the Original Proposal to propose 
the Consolidated Audit Trail Funding Fees, which would require Industry 
Members that are Exchange members to pay the CAT Fees determined by the 
Operating Committee.

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

    In response to the comments on the Original Proposal, the Operating 
Committee determined to make the following changes to the funding 
model: (1) Adds two additional CAT Fee tiers for Equity Execution 
Venues; (2) discounts the market share of Execution Venue ATSs 
exclusively trading OTC Equity Securities as well as the market share 
of the FINRA over-the-counter reporting facility (``ORF'') by the 
average shares per trade ratio between NMS Stocks and OTC Equity 
Securities (calculated as 0.17% based on available data from the second 
quarter of June 2017) when calculating the market share of Execution 
Venue ATS exclusively trading OTC Equity Securities and FINRA; (3) 
discounts the Options Market Maker quotes by the trade to quote ratio 
for options (calculated as 0.01% based on available data for June 2016 
through June 2017) when calculating message traffic for Options Market 
Makers; (4) discounts equity market maker quotes by the trade to quote 
ratio for equities (calculated as 5.43% based on available data for 
June 2016 through June 2017) when calculating message traffic for 
equity market makers; (5) decreases the number of tiers for Industry 
Members (other than the Execution Venue ATSs) from nine to seven; (6) 
changes the allocation of CAT costs between Equity Execution Venues and 
Options Execution Venues from 75%/25% to 67%/33%; (7) adjusts tier 
percentages and recovery allocations for Equity Execution Venues, 
Options Execution Venues and Industry Members (other than Execution 
Venue ATSs); (8) focuses the comparability of CAT Fees on the 
individual entity level, rather than primarily on the comparability of 
affiliated entities; (9) commences invoicing of CAT Reporters as 
promptly as possible following the latest of the operative date of the 
Consolidated Audit Trail Funding Fees for each of the Plan Participants 
and the operative date of the CAT NMS Plan amendment adopting CAT Fees 
for Plan Participants; and (10) requires the proposed fees to 
automatically expire two years from the operative date of the CAT NMS 
Plan amendment adopting CAT Fees for Plan Participants. On November 9, 
2017, the Exchange filed the First Amendment and proposed to amend the 
Original Proposal to reflect these changes.
    The Exchange submits this Second Amendment to revise the proposal 
as set

[[Page 59039]]

forth in the First Amendment to discount the OTC Equity Securities 
market share of all Execution Venue ATSs trading OTC Equity Securities, 
rather than applying the discount solely to those Execution Venue ATSs 
that exclusively trade OTC Equity Securities, when calculating the 
market share of Execution Venue ATS trading OTC Equity Securities. As 
discussed in the First Amendment:

    The Operating Committee determined to discount the market share 
of Execution Venue ATSs exclusively trading OTC Equity Securities as 
well as the market share of the FINRA ORF in recognition of the 
different trading characteristics of the OTC Equity Securities 
market as compared to the market in NMS Stocks. Many OTC Equity 
Securities are priced at less than one dollar--and a significant 
number at less than one penny--per share and low-priced shares tend 
to trade in larger quantities. Accordingly, a disproportionately 
large number of shares are involved in transactions involving OTC 
Equity Securities versus NMS Stocks. Because the proposed fee tiers 
are based on market share calculated by share volume, Execution 
Venue ATSs exclusively trading OTC Equity Securities and FINRA would 
likely be subject to higher tiers than their operations may 
warrant.\29\
---------------------------------------------------------------------------

    \29\ See Amendment No. 1 to SR-CHX-2016-08 (November 9, 2017) at 
32.

The Operating Committee believes that this argument applies equally to 
both Execution Venue ATSs exclusively trading OTC Equity Securities and 
to Execution Venue ATSs that trade OTC Equity Securities as well as 
other securities. Accordingly, the Exchange proposes to amend paragraph 
(b)(2) of the Consolidated Audit Trail Funding Fees to apply the 
discount to all Execution Venue ATSs trading OTC Equity Securities. 
Specifically, the Exchange proposes to change the parenthetical 
regarding the OTC Equity Securities discount in paragraph (b)(2) of the 
proposed fee schedule from ``with a discount for Equity ATSs 
exclusively trading OTC Equity Securities based on the average shares 
per trade ratio between NMS Stocks and OTC Equity Securities'' to 
``with a discount for OTC Equity Securities market share of Equity ATSs 
trading OTC Equity Securities based on the average shares per trade 
ratio between NMS Stocks and OTC Equity Securities.''
2. Statutory Basis
    The Exchange believes that the proposed rule change is consistent 
with the provisions of Section 6(b)(5) of the Act,\30\ which require, 
among other things, that the Exchange's rules must be designed to 
prevent fraudulent and manipulative acts and practices, to promote just 
and equitable principles of trade, and, in general, to protect 
investors and the public interest, and not designed to permit unfair 
discrimination between customers, issuers, brokers and dealer, and 
Section 6(b)(4) of the Act,\31\ which requires that exchange rules 
provide for the equitable allocation of reasonable dues, fees, and 
other charges among members and issuers and other persons using its 
facilities. The Exchange believes that the proposed change is 
consistent with the Act, and that the proposed fees are reasonable, 
equitably allocated and not unfairly discriminatory. In particular, the 
Exchange believes that the proposed change would treat all Equity ATSs 
trading OTC Equity Securities in a comparable manner when calculating 
applicable fees. In addition, the fee structure takes into 
consideration distinctions in securities trading operations of CAT 
Reporters, including all ATSs trading OTC Equity Securities.
---------------------------------------------------------------------------

    \30\ 15 U.S.C. 78f(b)(5).
    \31\ 15 U.S.C. 78f(b)(4).
---------------------------------------------------------------------------

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

    Section 6(b)(8) of the Act \32\ require that the Exchange's rules 
not impose any burden on competition that is not necessary or 
appropriate. 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. As previously 
described, the Exchange believes that the proposed rule change fairly 
and equitably allocates costs among CAT Reporters. In particular, the 
proposed fee schedule is structured to impose comparable fees on 
similarly situated CAT Reporters. The Exchange believes that the 
proposed change would treat all Equity ATSs trading OTC Equity 
Securities in a comparable manner when calculating applicable fees. In 
addition, the fee structure takes into consideration distinctions in 
securities trading operations of CAT Reporters, including all ATSs 
trading OTC Equity Securities. Moreover, the Operating Committee 
believes that the proposed changes address certain competitive concerns 
raised by commenters related to ATSs trading OTC Equity Securities.

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

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

    The Exchange set forth responses to comments received regarding the 
Original Proposal in the First Amendment. In addition, the proposed 
changes set forth in this Second Amendment further respond to comments 
made regarding ATSs trading OTC Equity Securities.
