Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”) and Rule 19b-4 thereunder, notice is hereby given that on January 6, 2017, National Stock Exchange, Inc. (“NSX” or the “Exchange”) filed with the Securities and Exchange Commission (“SEC” or “Commission”) a proposed rule change, as described in Items I, and II below, which Items have been substantially prepared by the Exchange.

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

In its filing with the Commission, the Exchange included statements concerning the purpose of and statutory 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 parts of such statements.

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

1. Purpose

On August 25, 2014, NYSE Group, Inc., on behalf of BZX, Bats BYX Exchange, Inc., f/k/a BATS-Y Exchange, Inc., Bats EDGA Exchange, Inc., Bats EDGX Exchange, Inc., Chicago Stock Exchange, Inc., Financial Industry Regulatory Authority, Inc. (“FINRA”), NASDAQ OMX BX, Inc., NASDAQ OMX PHLX LLC, the Nasdaq Stock Market LLC, New York Stock Exchange LLC (“NYSE”), NYSE MKT LLC, and NYSE Arca, Inc. (collectively “Participants”), filed with the Commission, pursuant to Section 11A of the Act and Rule 608 of Regulation NMS thereunder, the Plan to Implement a Tick Size Pilot Program (“Pilot”). The Participants filed the Plan to comply with an order issued by the Commission on June 24, 2014. The Plan was published for comment in the Federal Register on November 7, 2014 and was thereafter approved by the Commission, as modified, on May 6, 2015. On November 6, 2015, the Commission granted the Participants an exemption from implementing the Plan until October 3, 2016. On March 3, 2016, the Commission published an amendment to the Plan adding NSX as a Participant. On September 13, 2016, the Commission exempted the Plan Participants from the requirement to fully implement the Pilot on October 3, 2016, to permit the Plan Participants to implement the pilot on a phased-in basis, as described in the Plan Participants' exemptive request.

The Plan is designed to allow the Commission, market participants, and the public to study and assess the impact of increment conventions on the liquidity and trading of the common stocks of small-capitalization companies. Each Participant is required to comply, and to enforce compliance by its member organizations, as applicable, with the provisions of the Plan.

The Exchange adopted rule amendments to implement the requirements of the Plan, including relating to the Plan's data collection requirements and requirements relating to Web site data publication. Specifically, with respect to the Web site data publication requirements pursuant to Section VII and Appendices B and C to the Plan, Exchange Rule 11.26(b)(2)(B) provides, among other things, that the Exchange shall make the data required by Items I and II of Appendix B to the Plan, and collected pursuant to paragraph (b)(2) of Rule 11.26, publicly available on the Exchange's Web site on a monthly basis at no charge and shall not identify the Trading Center that generated the data. Exchange Rule 11.26(b)(3)(C), provides, among other things, that the Exchange shall make the data required by Item IV of Appendix B to the Plan, and collected pursuant to paragraph (b)(3)(A) of Rule 11.26, publicly available on the Exchange Web site on a monthly basis at no charge and shall not identify the Trading Center [sic] that generated the data. Exchange Rule 11.26(b)(5) provides, among other things, that the Exchange shall collect and transmit to the Commission data described in Item III of Appendix B of the Plan relating to daily Market Maker registration statistics, but does not currently include a provision requiring the Exchange to publish such data to its Web site. Rule 11.26, Interpretation and Policy .08 provides, among other things, that the requirement that the Exchange or the Designated Examining Authority (“DEA”) make certain data publicly available on the Exchange's or the DEA's Web site pursuant to Appendix B and C to the Plan shall commence at the beginning of the Pilot Period.

The Exchange is proposing amendments to Rule 11.26(b)(2)(B) (regarding Appendix B.I and B.II data) and Rule 11.26(b)(3)(C) (regarding Appendix B.IV data) to provide that data required to be made available on the Exchange's Web site be published within 120 calendar days following month end. The Exchange also proposes to add a provision to Rule 11.26(b)(5) to state that the Exchange shall make data collected under Appendix B.III publicly available on the Exchange's Web site within 120 calendar days following month end at no charge. In addition, the proposed amendments to Rule 11.26, Interpretations and Policies .08 would provide that, notwithstanding the provisions of paragraphs (b)(2)(B), (b)(3)(C), and (b)(5), the Exchange or the DEA shall make data for the Pre-Pilot period publicly available on the Exchange's or the DEA's Web site pursuant to Appendix B and C to the Plan by February 28, 2017. The purpose of delaying the publication of the Web site data is to address confidentiality concerns by providing for the passage of additional time between the market information reflected in the data and the public availability of such information.

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 prevent fraudulent and manipulative acts and practices, 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.

The Exchange believes that this proposal is consistent with the Act because it is designed to assist the Participants in meeting their regulatory obligations pursuant to the Plan and is in furtherance of the objectives of the Plan, as identified by the SEC. The Exchange further believes that the instant proposal is consistent with the Act in that it is designed to address confidentiality concerns by permitting the Exchange to delay Web site publication to provide for passage of additional time between the market information reflected in the data and the public availability of such information.

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, and is designed to assist the Participants in meeting their regulatory obligations pursuant to the Plan.

The proposal is intended to address confidentiality concerns that may adversely impact competition by permitting the Exchange to delay Web site publication to provide for passage of additional time between the market information reflected in the data and the public availability of such information. The proposal also does not alter the information required to be submitted to the Commission.

C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From ETP Holders, 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 Exchange Act and Rule 19b-4(f)(6) thereunder.

A proposed rule change filed under paragraph (f)(6) of Rule 19b-4 normally does not become operative prior to 30 days after the date of the filing. However, pursuant to Rule 19b-4(f)(6)(iii), the Commission may designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange filed the proposed rule change for immediate effectiveness and has requested that the Commission waive the requirement that the proposed rule change not become operative for 30 days after the date of the filing so that it may become operative immediately.

The Exchange notes that the proposed rule change implements the provisions of the Plan, and is designed to assist the Participants in meeting their regulatory obligations pursuant to the Plan. The proposal is intended to address confidentiality concerns by permitting the Exchange to delay Web site publication to provide for passage of additional time between the market information reflected in the data and the public availability of such information. The proposal does not alter the information required to be submitted to the SEC.

The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest because it will allow the Exchange to implement proposed changes that are intended to address confidentiality concerns. Therefore, the Commission hereby waives the 30-day operative delay and designates the proposed rule change to be operative as of 6 January, 2017.

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, otherwise in furtherance of the purposes of the Act. If the Commission takes such action, the Commission shall institute proceedings to determine whether the proposed rule should be approved or disapproved.
