Rule 3100. Trading Halts on PSX
(a) Authority to Initiate Trading Halts or Pauses
In circumstances in which the Exchange deems it necessary to protect investors and the public interest, and pursuant to the procedures set forth in paragraph (c):
(1)-(3) No change.
(4) If a primary listing market issues an individual stock trading pause in any of the Circuit Breaker Securities, as defined herein, the Exchange will pause trading in that security until trading has resumed on the primary listing market. If, however, trading has not resumed on the primary listing market and ten minutes have passed since the individual stock trading pause message has been received from the responsible single plan processor, the Exchange may resume trading in such stock. The provisions of this paragraph (a)(4) shall be in effect during a pilot set to end on the earlier of the initial date of operations of the Regulation NMS Plan to Address Extraordinary Market Volatility or February 4, 201 4. During the pilot, the term “Circuit Breaker Securities” shall mean any NMS stock except rights and warrants.
(b)-(c) No change.

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
On June 10, 2010, the Commission granted accelerated approval for a pilot period to end December 10, 2010 of proposed rule changes submitted by the BATS Exchange, Inc., NASDAQ OMX BX, Inc., Chicago Board Options Exchange, Incorporated, Chicago Stock Exchange, Inc., EDGA Exchange, Inc., EDGX Exchange, Inc., International Securities Exchange LLC, The NASDAQ Stock Market LLC (“NASDAQ”), New York Stock Exchange LLC (“NYSE”), NYSE MKT LLC (“NYSE MKT”) (formerly, NYSE Amex LLC), NYSE Arca, Inc. (“NYSE Arca”), and National Stock Exchange, Inc. (collectively, the “Exchanges”), to pause trading during periods of extraordinary market volatility in S&P 500 stocks.
The rules require the Listing Markets 
to issue five-minute trading pauses for individual securities for which they are the primary Listing Market if the transaction price of the security moves ten percent or more from a price in the preceding five-minute period. The Listing Markets are required to notify the other Exchanges and market participants of the imposition of a trading pause by immediately disseminating a special indicator over the consolidated tape. Under the rules, once the Listing Market issues a trading pause, the other Exchanges are required to pause trading in the security on their markets. On September 10, 2010, the Commission approved the respective rule filings of the Exchanges to expand application of the pilot to securities comprising the Russell 1000® Index and specified Exchange Traded Products.
In connection with its resumption of trading of NMS Stocks through the NASDAQ OMX PSX system, the Exchange adopted Rule 3100(a)(4) so that it could participate in the pilot program.
On September 29, 2010, the Exchange amended Rule 3100(a)(4) to include stocks comprising the Russell 1000® Index and specified Exchange Start Printed Page 11938Traded Products.
On December 7, 2010, the Exchange filed an immediately effective filing to extend the existing pilot program for four months, so that the pilot would expire on April 11, 2011.
On March 31, 2011, the Exchange filed an immediately effective filing to extend the pilot period an additional four months, so that the pilot would expire on August 11, 2011 or the date on which a limit up/limit down mechanism to address extraordinary market volatility, if adopted, applies.
On June 23, 2011, the Commission approved the expansion of the pilot to all NMS stocks, but with different pause-triggering thresholds.
On August 8, 2011, the Exchange filed an immediately effective filing that removed language from the rule that tied the expiration of the pilot to the adoption of a limit up/limit down mechanism to address extraordinary market volatility, and further extended the pilot period, so that the pilot would expire on January 31, 2012.
On November 18, 2011, the Exchange filed an immediately effective filing that excluded rights and warrants from the pilot.
On January 23, 2012, the Commission approved an extension of the pilot to July 31, 2012.
On May 31, 2012, the Commission approved, on a pilot basis, the National Market System Plan to Address Extraordinary Market Volatility.
This plan creates a market-wide limit up-limit down mechanism that is intended to address extraordinary market volatility in NMS Stocks, with a planned implementation date of February 4, 2013. Once implemented, the limit up/limit down mechanism to address extraordinary market volatility will render the current stock trading pause pilot duplicative and unnecessary. The Exchange filed a rule change proposal to extend the single stock trading pause pilot so that it will now expire on February 4, 2013, when the limit up/limit down mechanism to address extraordinary market volatility is to be implemented.
The Exchange, in conjunction with the Exchanges and FINRA, recently filed an amendment to the Plan to change the date of initial operations of the Plan from February 4, 2013 to April 8, 2013. Accordingly, the Exchange is proposing to extend the expiration of the trading pause pilot to the earlier of the initial date of operations of the Plan or February 4, 2014 to allow adequate time for the Plan's implementation. The Exchange believes that the pilot program has been successful in reducing the negative impacts of sudden, unanticipated price movements in the securities covered by the pilot. The Exchange also believes that an additional extension of the pilot is warranted so that it may continue to apply the circuit breaker to reduce the negative impacts of sudden, unanticipated price movements until it is replaced by the limit up/limit down mechanism.
2. Statutory Basis
The statutory basis for the proposed rule change is Section 6(b)(5) of the Act, which requires the rules of an exchange 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. The Exchange believes that the change proposed herein meets these requirements in that it promotes uniformity across markets concerning decisions to pause trading in a security when there are significant price movements, which promotes just and equitable principles of trade and removes impediments to, and perfects the mechanism of, a free and open market and a national market system. Additionally, extension of the pilot until the earlier of the initial date of operations of the Plan or February 4, 2014 would allow the pilot to continue to operate without interruption while the Exchange and the Commission further assess the effect of the pilot on the marketplace or whether other initiatives should be adopted in lieu of the current pilot, which contributes to the protection of investors and the public interest.
B. Self-Regulatory Organization's Statement on Burden on Competition
The Exchange 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, as amended. The proposed changes are being made to extend the operation of the trading pause pilot until the earlier of the initial date of operations of the Plan or February 4, 2014 would allow the pilot to continue to operate without interruption until implementation of the Plan, which contributes to the protection of investors and the public interest. Other competing equity exchanges are subject to the same trading pause requirements specified in the Plan. Thus, the proposed changes will not impose any burden on competition while providing trading pause requirements specified in the Plan.
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
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.
A proposed rule change filed under Rule 19b-4(f)(6) 
normally does not become operative prior to 30 days after the date of the filing. However, pursuant to Rule 19b-4(f)(6)(iii),
the Start Printed Page 11939Commission may designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has asked the Commission to waive the 30-day operative delay so that the proposal may become operative immediately upon filing. 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 allow the pilot program to continue uninterrupted. Accordingly, the Commission hereby grants the Exchange's request and designates the proposal 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.
