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 Statutory Basis for, the Proposed Rule Change

1. Purpose

The Exchange proposes to amend Exchange Rule 1703 to make a few minor, non-substantive edits and clarifying changes to provide accuracy and precision within the rule text.

Specifically, the Exchange proposes to amend Exchange Rules 1703(a)(1) and 1703(a)(2) to modify the references to paragraph (3) to instead refer to paragraph (a)(3). The purpose of the proposed changes is to clarify that such references are to paragraph (a)(3) and are not intended to refer to any other paragraph.

In addition, the Exchange proposes to add a closing parenthesis after the phrase “Industry Member Data” for grammatical correctness and clarity in the rule text of paragraph (a)(2). The purpose of the proposed change is to provide accuracy and precision within the rule text.

2. Statutory Basis

The Exchange believes that the proposed changes are consistent with Section 6(b) of the Act ^[3] in general, and further the objectives of Section 6(b)(1) of the Act ^[4] in particular, in that they are designed to enforce compliance by the Exchange's Members ^[5] and persons associated with its Members, with the provisions of the rules of the Exchange. In particular, the Exchange believes that the proposed changes will provide greater clarity to Members and the public regarding the Exchange's Rulebook by correcting grammatical errors and providing accuracy and ( printed page 66748) consistency within the Exchange's Rulebook. The proposed changes will also make it easier for Members to interpret the Exchange's Rulebook.

The Exchange believes that the proposed rule changes also further the objectives of Section 6(b)(5) of the Act. In particular, they are designed to prevent fraudulent and manipulative acts and practices, promote just and equitable principles of trade, foster cooperation and coordination with persons engaged in regulating, clearing, settling, processing information with respect to, and facilitating transactions in securities, remove impediments to and perfect the mechanisms of a free and open market and a national market system and, in general, protect investors and the public interest. The Exchange believes the proposed changes would promote just and equitable principles of trade and remove impediments to and perfect the mechanism of a free and open market and a national market system because the proposed rule changes would provide greater clarity to Members and the public regarding the Exchange's Rulebook by correcting grammatical errors and providing accuracy and consistency within the Exchange's Rulebook. It is in the public interest for the Exchange's Rulebook to be accurate and concise so as to eliminate the potential for confusion.

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

The Exchange does not believe that the proposed changes will impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Act. Specifically, the Exchange believes the proposed changes will not impose any burden on intra-market competition as there is no functional change to the Exchange's System ^[6] and because the rules of the Exchange apply to all Members equally. The proposed rule changes will have no impact on competition as they are not designed to address any competitive issue but rather are designed to remedy minor, non-substantive issues and provide added clarity to the Exchange's Rulebook. In addition, the Exchange does not believe the proposal will impose any burden on inter-market competition as the proposal does not address any competitive issues and is intended to protect investors by providing further transparency and accuracy regarding the Exchange's Rulebook.

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

Written comments were neither solicited nor received.

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 after the date of the filing, or such shorter time as the Commission may designate, it has become effective pursuant to Section 19(b)(3)(A) of the Act ^[7] and subparagraph (f)(6) of Rule 19b-4 thereunder.^[8]

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) ^[9] of the Act to determine whether the proposed rule change should be approved or disapproved.
