Self-Regulatory Organizations; New York Stock Exchange LLC; Notice of Filing and Immediate Effectiveness of Proposed Rule Change Relating to the Extension of the Pilot Until March 24, 2006 To Put Into Operation Phase 1 of the NYSE HYBRID MARKETSM

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 March 13, 2006, the New York Stock Exchange LLC (“NYSE” 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 prepared by the Exchange. NYSE filed the proposed rule change pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6) thereunder, which renders the proposal 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 proposes to extend the pilot which put into operation Phase 1 of the NYSE HYBRID MARKET (“Hybrid Market”) initiative (“Pilot”) proposed in SR-NYSE-2004-05 and amendments thereto (“Hybrid Market filings”).

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 self-regulatory organization 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

On December 14, 2005, the Commission approved the Pilot to put into operation Phase 1 of the Hybrid Market initiative with respect to a group of securities, known as Phase 1 Pilot securities (“Pilot securities”). The approval provided that the Pilot would terminate the earlier of: (1) March 14, 2006 or (2) Commission action on the Hybrid Market proposal.

The Exchange proposes to extend the Pilot through March 24, 2006, while the Commission continues to review the Hybrid Market filings.

The Exchange believes that an extension of the Pilot through March 24, 2006 will allow the Exchange to continue to conduct real-time system and user testing of certain features of the Hybrid Market filings in order to be in a position to comply with the implementation of Regulation NMS.

The Exchange believes the Pilot has proven beneficial from both a technology and a training perspective. It has given the Exchange the opportunity to identify and address any system problems and to identify and incorporate beneficial system changes that become apparent as a result of usage in real time and under real market conditions. The ability to have such real time user interface is invaluable, as it is impossible to accurately anticipate behavioral changes in a development or mock-trading environment. In addition, the Pilot has allowed users to gain essential practical experience with the new systems and processes in a well-modulated way.

The Pilot has operated with minimal problems given the amount and degree of testing and training that has occurred to date.

Therefore, the Exchange believes it is appropriate to extend the Pilot through March 24, 2006.

2. Statutory Basis

The Exchange believes that the proposed rule change 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 foster cooperation and coordination with persons engaged in regulating, clearing, settling, processing information with respect to, and 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 the proposed rule change is also designed to support the principles of Section 11A(a)(1) of the Act in that it seeks to assure economically efficient execution of securities transactions, make it practicable for brokers to execute investors' orders in the best market, and provide an opportunity for investors' orders to be executed without the participation of a dealer.

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

The Exchange has neither solicited nor received written 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 significantly affect the protection of investors or the public interest; does not impose any significant burden on competition; and by its terms, does not become operative for 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, it has become effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6) thereunder.

A proposed rule change filed under Rule 19b-4(f)(6) normally may not become operative prior to 30 days after the date of filing. However, Rule 19b-4(f)(6)(iii) 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 five-day pre-filing notice requirement and the 30-day operative delay and designate the proposed rule change immediately operative upon filing. The Commission believes that waiver of the five-day pre-filing notice requirement and the 30-day operative delay is consistent with the protection of investors and the public interest because it would allow the Pilot to continue without interruption. Accordingly, the Commission designates the proposal to be effective and operative upon filing with the Commission.

At any time within 60 days of the filing of the 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.
