          - [Release No. 34-55340; File No. SR-NYSEArca-2007-18] 

                    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 February 22, 2007, the NYSE Arca, Inc. (“NYSE Arca” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I and II below, which Items have been substantially prepared by NYSE Arca. The Exchange has filed the proposal as a “non-controversial” rule change pursuant to Section 19(b)(3)(A) of the Act [3]                                          and Rule 19b-4(f)(6) thereunder,[4]                                          which renders it effective upon filing with the Commission. 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 

                    NYSE Arca proposes to clarify the operative date of the rule changes made in connection with Regulation NMS,[5]                                          from February 4, 2007 to March 5, 2007.[6]                                          There is no new rule text.                 

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

In its filing with the Commission, NYSE Arca 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. NYSE Arca 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 proposed rule change clarifies the operative date of the rule changes made in connection with Regulation NMS [7]                                          from February 4, 2007 to March 5, 2007. This clarification stems in part from the Commission's extension of the Trading Phase Date of Regulation NMS to March 5, 2007.[8] 

#### 2. Statutory Basis 

                    NYSE Arca believes the proposed rule change is consistent with Section 6(b) of the Act,[9]                                          in general, and furthers the objectives of Section 6(b)(5) of the Act,[10]                                          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, and to remove impediments to and perfect the mechanism of a free and open market and a national market system.                 

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

The Exchange 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. 

### 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.                           ( print page 9823)    

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

                    Because the forgoing rule change does not: (1) Significantly affect the protection of investors or the public interest; (2) impose any significant burden on competition; and (3) become operative for 30 days after the date of this filing, or such shorter time as the Commission may designate, it has become effective pursuant to Section 19(b)(3)(A) of the Act [11]                                          and Rule 19b-4(f)(6) thereunder.[12] 

                    A proposed rule change filed under 19b-4(f)(6) normally may not become operative prior to 30 days after the date of filing.[13]                                          However, Rule 19b-4(f)(6)(iii) [14]                                          permits the Commission to designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has requested that the Commission waive the 30-day operative delay. The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest because such waiver would permit the Exchange rules to immediately reflect the new Trading Phase Date, March 5, 2007. For this reason, the Commission designates the proposed rule change to be operative upon filing with the Commission.[15] 

At any time within 60 days of the filing of such proposed rule change the Commission may summarily abrogate 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.
