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 November 9, 2015, NASDAQ OMX BX, Inc. (“BX” or the “Exchange”) filed with the Securities and Exchange Commission (“SEC” or “Commission”) 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 on the proposed rule change from interested persons.

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

The Exchange proposes to amend BX Rules at Chapter VI, Section 9, entitled “Price Improvement Auction (“PRISM”),” to correct two cross-references to BX Rules. The text of the proposed rule change is available on the Exchange's Web site at http://nasdaqomxbx.cchwallstreet.com , at the principal office of the Exchange, and at 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 Exchange 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 Exchange 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

The Exchange proposes to amend BX Rules at Chapter VI, Section 9, entitled “Price Improvement Auction (“PRISM”)” to correct two cross-references to BX Rules. Specifically, the Exchange cited to its Size Pro-Rata allocation algorithm in the BX PRISM Rule at Chapter VI, Section 9(ii)(E). The cite was to Chapter VI, Section 10(1)(C)(1)(a) when it should have cited to Section 10(1)(C)(2). Further, the Exchange cited to its Price/Time allocation algorithm in the BX PRISM Rule at Chapter VI, Section 9(ii)(F). The cite was to Chapter VI, Section 10(1)(C)(2)(1) when it should have cited to Section 10(1)(C)(1). These clarifications to the BX PRISM rule will update the Rulebook and help avoid confusion for Participants. The proposed changes are non-substantive rule changes.

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 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, by correcting citation errors within the BX Rulebook.

The Exchange's proposal to correct the citations will serve to avoid confusion as to the correct algorithm. The proposed changes are non-substantive rule changes.

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

BX does not believe that the proposed rule change will impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act. The proposed changes do not impose any burden on competition, rather, the non-substantive rule changes correct incorrect references within the Rulebook. As a result, there will be no substantive changes to the Exchange's operations or its rules.

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 has filed the proposed rule change pursuant to Section 19(b)(3)(A)(iii) of the Act and Rule 19b-4(f)(6) thereunder. Because the 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 prior to 30 days from the date on which it was filed, or such shorter time as the Commission may designate, if consistent with the protection of investors and the public interest, the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6)(iii) thereunder.

The Exchange has asked the Commission to waive the 30-day operative delay so that the proposal may become operative immediately upon filing. The Exchange has stated that updating the existing rule text to reflect the correct citations sooner, rather than later, will avoid confusion for Participants. The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest because this waiver will enable the Exchange to provide the correct citations to the applicable allocation rules for its PRISM rule in a timely manner, and thereby avoid confusion for the Exchange's Participants with respect to how PRISM executions would be allocated. For this reason, the Commission hereby waives the 30-day operative delay requirement and designates the proposed rule change as operative upon filing.

At any time within 60 days of the filing of such 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 change should be approved or disapproved.
