Start Preamble March 9, 2017.

Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) ^[1] and Rule 19b-4 thereunder,^[2] notice is hereby given that on March 3, 2017, Financial Industry Regulatory Authority, Inc. (“FINRA”) filed with the Securities and Exchange Commission (“SEC” or “Commission”) the proposed rule change as described in Items I, II, and III below, which Items have been prepared by FINRA. 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

FINRA is proposing to amend Rule 6191 to implement an anonymous, grouped masking methodology for over-the-counter (“OTC”) activity in connection with Web site data publication of Appendix B data pursuant to the Regulation NMS Plan to Implement a Tick Size Pilot Program (“Plan”).

The text of the proposed rule change is available on FINRA's Web site at http://www.finra.org, at the principal office of FINRA and at the Commission's Public Reference Room.Start Printed Page 13902

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

In its filing with the Commission, FINRA 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. FINRA 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

1. Purpose

Rule 6191(b) (Compliance with Data Collection Requirements) ^[3] implements the data collection and Web site publication requirements of the Plan.^[4] Rule 6191(b)(2)(B) provides, among other things, that FINRA will publish data pursuant to Appendix B.I. and B.II. of the Plan on its Web site within 120 calendar days following month end at no charge,^[5] and that such publication will not identify the Trading Center that generated the data. Rule 6191(b)(3)(C) provides, among other things, that FINRA will publish data pursuant to Appendix B.IV. to the Plan on its Web site within 120 calendar days following month end at no charge, and that such publication will not identify the OTC Trading Center that generated the data.

In consultation with SEC staff, FINRA is proposing new supplementary material to Rule 6191 to implement the aggregation methodology described further below. Specifically, FINRA is proposing to provide for an anonymous, grouped masking methodology for Appendix B.I., B.II. and B.IV. data in furtherance of the Plan's requirement that the data made publicly available will not identify the Trading Center that generated the data.^[6] The proposed methodology also is intended to mitigate confidentiality concerns previously raised by commenters ^[7] regarding the publication of data related to OTC activity. Chicago Stock Exchange, Inc. (“CHX”) is the designated examining authority (“DEA”) for a relatively small number of OTC Trading Centers; thus, FINRA also will incorporate the firms for which CHX is the DEA into the anonymous, grouped masking methodology and publish OTC-wide statistics for Appendix B.I., B.II. and B.IV. data on the FINRA Web site.^[8]

Grouping Methodology

For purposes of the data to be made available on the FINRA Web site pursuant to the Plan, FINRA proposes to aggregate individual OTC Trading Center Appendix B data within groupings of Trading Centers by ATS and non-ATS categories, using an undisclosed methodology for assigning each Trading Center to a group. FINRA believes that an anonymous, grouped masking methodology for purposes of publishing the required data related to OTC activity will support the Plan's requirement that the data to be made publicly available will not identify the Trading Center that generated the data.^[9] In furtherance of this objective, the details of the methodology used to formulate the anonymous groupings will not be disclosed. FINRA believes that the proposed approach strikes an appropriate balance between mitigating confidentiality concerns while supporting the public availability of useful Plan data.

Trading Center group assignments will not be published and generally will remain unchanged for the duration of the data publication period, with the exception of the entrance of a new Trading Center (new FINRA member). The anonymized identifier used for each group will remain unchanged for the duration of the data publication period and the same groups and group identifiers will be used for all Appendix B data sets. The number of Trading Centers assigned to each group will not specifically be disclosed; however, each group will contain between five and 25 market participant identifiers (MPIDs). In addition, for each day's statistics, the number of MPIDs in each group with activity in any Pilot Security for that day will be disclosed. Disclosing the number of active MPIDs each day is intended to inform evaluators of the data of whether the number of Trading Centers reflected in the statistics each day has changed—for example, because a Trading Center in the group didn't register activity on a given day.^[10]

Appendix B.I. Data Aggregation Methodology

FINRA proposes to aggregate the Appendix B.I. data to be made publicly available on the FINRA Web site by aggregating statistics within each group by Pilot Security for each trading day. The methodology used for computing the statistics at the group level will be the same methodology used to compute these statistics at the Trading Center level in the non-public version of the data (and in the public version of the exchange data).^[11] Specifically, FINRA would calculate group-level sums for statistics that are quantity counts ^[12] and use all underlying data within a group to calculate statistics requiring averages or weighted averages.^[13] Data will be aggregated separately for each order Start Printed Page 13903type and subcategory, and will not be aggregated across order types or subcategories.

Appendix B.II. Data Aggregation Methodology

Appendix B.II. data includes order-level statistics; thus, FINRA proposes that all individual orders be displayed for all Trading Centers within a group, with each order attributed to the group rather than the underlying Trading Center. In addition, Appendix B.II. order information would be displayed in pure chronological order based on time of order receipt to help minimize confidentiality concerns that may occur if other ordering methods were used, such as showing the original chronological order per Trading Center.

Appendix B.IV. Data Aggregation Methodology

FINRA proposes to aggregate Appendix B.IV. data by aggregating statistics within each group by trading day by summing the statistics of all market maker activity represented within the group. The number of market makers would be displayed as the unique number of market makers ^[16] across all Trading Centers within the group.

If the Commission approves the proposed rule change, the effective date of the proposed rule change will be 120 days following Commission approval.

2. Statutory Basis

FINRA believes that the proposed rule change is consistent with the provisions of Section 15A(b)(6) of the Act,^[18] which requires, among other things, that FINRA 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 Section 15A(b)(9) of the Act,^[19] which requires that FINRA rules not impose any burden on competition that is not necessary or appropriate.

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 stock of small-capitalization companies. FINRA consulted extensively with SEC staff in connection with the instant proposal to design a grouped masking methodology that is consistent with the objectives of Section VII(A) of the Plan to make Appendix B data publicly available while not identifying the Trading Center that generated the data.

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

FINRA 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. FINRA 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

The Commission previously received comment letters from FIF and Citadel Securities expressing concern over FINRA's intent to publish Appendix B data on a Trading Center-by-Trading Center basis.^[20] FIF stated that publishing Appendix B.I. and B.II. statistics on FINRA's Web site in a disaggregated format does not satisfy the requirements of the Plan or Rule 6191 that the publicly available data will not identify the trading center that generated the data.^[21] Similarly, Citadel Securities stated that market participants would be able to determine the identity of Trading Centers in violation of the Plan if the Appendix B data were to be published in a disaggregated format.^[22]

In consultation with SEC staff, FINRA is filing the instant proposed rule change to mitigate the confidentiality concerns raised by commenters by providing for an anonymized, grouped masking methodology for Appendix B data for all OTC activity in furtherance of the objectives of the Plan.

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

Within 45 days of the date of publication of this notice in the Federal Register or within such longer period (i) as the Commission may designate up to 90 days of such date if it finds such longer period to be appropriate and publishes its reasons for so finding or (ii) as to which the self-regulatory organization consents, the Commission will:

(A) By order approve or disapprove such proposed rule change, or

(B) institute proceedings to determine whether the proposed rule change should be disapproved.
