May 24, 2017.
Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”),
and Rule 19b-4 
thereunder, notice is hereby given that on May 15, 2017, the Chicago Stock Exchange, Inc. (“CHX” or the “Exchange”) filed with the Securities and Exchange Commission (“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
CHX proposes to amend Article 20, Rule 13(b) of the Rules of the Exchange (“CHX Rules”) to modify certain Appendix B Web site data publication requirements pursuant to the Regulation NMS Plan to Implement a Tick Size Pilot Program (“Plan”).
The text of this proposed rule change is available on the Exchange's Web site 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 Start Printed Page 25028statements 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.
A. Self-Regulatory Organization's Statement of the Purpose of, and the Statutory Basis for, the Proposed Rule Change
Article 20, Rule 13(b) (Compliance with Data Collection Requirements) 
implements the data collection and Web site publication requirements of the Plan.
Article 20, Rule 13(b)(2)(A) requires, among other things, that a CHX Participant 
that operates a Trading Center subject to the Plan and for which the Exchange is the designated examining authority (“DEA”) shall collect and transmit to the Exchange data described under Items I and II of Appendix B of the Plan. Subparagraph (v) under Article 20, Rule 13(b)(2)(A) provides, among other things, that the Exchange shall publish such Appendix B.I. and B.II. data on the CHX Web site within 120 calendar days following month end at no charge and shall not identify the Trading Center that generated the data. Paragraph .08 of the Interpretations and Policies under Article 20, Rule 13(b) provides, among other things, that the requirement that the Exchange make certain data publicly available on the Exchange or DEA's Web site pursuant to Appendix B and C to the Plan shall commence at the beginning of the Pilot Period,
and that the Exchange shall make Appendix C.I data available to the Financial Industry Regulatory Authority (“FINRA”) for aggregation and publication on the FINRA Web site pursuant to FINRA Rules and the Exchange will publish Appendix B data on the Exchange Web site, which shall commence on August 31, 2017.
The Exchange is proposing to amend certain provisions under Article 20, Rule 13(b) to comport to recent amendments to FINRA Rule 6191 
that were adopted to mitigate confidentiality concerns previously raised by commenters 
regarding the publication of data related to over-the-counter (“OTC”) activity. Given that the Exchange is the DEA for a relatively small number of OTC Trading Centers, publishing their data, whether on an aggregated or a disaggregated basis, raises concerns that the identities of these Trading Centers could be determined. In order to address these concerns, pursuant to paragraph .15 of the Supplementary Materials of FINRA Rule 6191, FINRA will incorporate the firms for which the Exchange is the DEA into the anonymous, grouped masked methodology and publish OTC-wide statistics for Appendix B.I, B.II. and B.IV. data on the FINRA Web site.
The Exchange will publish Appendix B data with respect to any Trading Center operated by the Exchange on the Exchange Web site. Thus, the Exchange proposes to amend the CHX Rules as follows:
- Amend Article 20, Rule 13(b)(2)(A)(v) to modify the Web site publication requirement to provide that the Exchange shall make the Appendix B.I. and B.II. data collected pursuant to current Article 20, Rule 13(b)(2)(A) available to FINRA for aggregation and publication on the FINRA Web site pursuant to FINRA Rules.
- Amend paragraph .08 of the Interpretations and Policies of Article 20, Rule 13(b) to provide that notwithstanding the provisions of Article 20, Rule 13(b)(2) and (b)(3), with respect to data for the Pre-Pilot Period and the Pilot Period, the Exchange shall make the Appendix B.I. and B.II. data collected pursuant to Article 20, Rule 13(b)(2)(A) and the Appendix C.I. data collected pursuant to Article 20, Rule 13(b)(4)(A) available to FINRA for aggregation and publication on the FINRA Web site pursuant to FINRA Rules and the Exchange will publish Appendix B data with respect to any Trading Center operated by the Exchange on the Exchange Web site, which shall commence on August 31, 2017.
2. Statutory Basis
The Exchange believes that its proposal is consistent with Section 6(b) of the Act 
in general, and furthers the objectives of Section 6(b)(5) of the Act 
in particular, in that it is designed to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in facilitating transactions in securities, 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; and are not designed to permit unfair discrimination between customers, issuers, brokers, or dealers.
The Plan is designed to allow the Commission, market participants, and the public to study and assess the Start Printed Page 25029impact of increment conventions on the liquidity and trading of the common stock of small-capitalization companies. The Exchange believes that this proposal is consistent with the Act and Section VII(A) of the Plan because it mitigates confidentiality concerns regarding the identity of certain OTC Trading Centers for which the Exchange is the DEA.
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 Exchange notes that the proposed rule change implements the provisions of the Plan.
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 Exchange asserts that the proposed rule change: (1) Will not significantly affect the protection of investors or the public interest, (2) will not impose any significant burden on competition, and (3) and will not become operative for 30 days from the date on which it was filed, or such shorter time as the Commission may designate. In addition, the Exchange provided the Commission with 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, or such shorter time as designated by the Commission.
The Exchange believes that the proposed rule change raises no novel issues. The Exchange notes that the proposed rule change is intended to address the requirement in Section VII(A) of the Plan that the data made publicly available will not identify the Trading Center that generated the data, as well as the confidentiality concerns raised in connection with the publication of Appendix B data.
The Exchange also notes that the proposal does not alter the information required to be submitted to the SEC. As such, the Exchange has designated this rule filing as non-controversial under Section 19(b)(3)(A) of the Act 
and paragraph (f)(6) of Rule 19b-4 thereunder.
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 shall institute proceedings under Section 19(b)(2)(B) of the Act to determine whether the proposed rule should be approved or disapproved.
