July 5, 2012.
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 June 22, 2012, NASDAQ OMX PHLX LLC (“Phlx” or “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 clarify the functioning of the Post-Only Order in NASDAQ OMX PSX (“PSX”). If the Commission waives the pre-operative delay provided for in Rule 19b-4(f)(6),
Phlx proposes to implement the proposed rule change immediately. The text of the proposed rule change is available at http://nasdaqomxphlx.cchwallstreet.com/nasdaqomxphlx/phlx/, at Phlx's principal office, 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 Statutory Basis for, the Proposed Rule Change
Phlx proposes to clarify the functionality associated with its existing Post-Only Order on PSX. Last year, Phlx submitted a proposed rule change that changed the functionality of this order type.
In the course of describing and clarifying the order's then-existing functionality, however, SR-Phlx-2011-70 erroneously characterized one aspect of the functioning of the order and, as a result, introduced erroneous language into the rule text describing the rule.
If a Post-Only Order would lock an order on PSX at the time of entry, the order is re-priced and displayed by the System to one minimum price increment (i.e., $0.01 or $0.0001) below the current low offer (for bids) or above the current best bid (for offers). Thus, if the best bid and best offer on the PSX book were $10.00 x $10.05, and a market participant entered a Post-Only Order to buy at $10.05, the order would be re-priced and displayed at $10.04. However, SR-Phlx-2011-70 erroneously stated that if a Post-Only Order would cross an order on the System, the order would be repriced as described above unless the value of price improvement associated with executing against a resting order equals or exceeds the sum of fees charged for such execution and the value of any rebate that would be provided if the order posted to the book and subsequently provided liquidity, in which case the order will execute. In fact, in a case where the order crosses an order on the System, the order will be repriced, and will not execute. Accordingly, Phlx is deleting language from the rule that states otherwise.
The error occurred because the functionality to consider pricing was described in the original filing to establish a Post-Only Order on The NASDAQ Stock Market LLC (“NASDAQ”) and was implemented on that market, but was not fully reflected in the text of NASDAQ Rule 4751.
Subsequently, Phlx adopted identical rule text when it established PSX as its new facility for trading cash equity securities, but did not implement the price consideration functionality due to its inconsistency with model of allocating executions of incoming orders among posted orders pro rata based on their size.
In May 2011, NASDAQ filed a proposed rule change to modify the repricing behavior of its Post-Only Order, and added rule language to clarify the existing price-consideration functionality of its order.
When Phlx opted to make a corresponding change to the repricing behavior of its Post-Only Order, it was assumed that a corresponding change to describe price consideration behavior was also required. In fact, no such change was needed since the behavior of the PSX order is not identical to that of the NASDAQ order.
2. Statutory Basis
Phlx believes that the proposed rule change is consistent with the provisions of Section 6 of the Act,
in general, and with Section 6(b)(5) of the Act,
in particular, in that the proposal 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 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. Phlx believes that the change is necessary to reflect accurately the functioning of PSX's Post-Only Order.
B. Self-Regulatory Organization's Statement on Burden on Competition
Phlx 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.
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 Commission 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 doing so will allow the rule text describing the Post-Only Order to describe its functionality accurately without delay. Accordingly, the Commission designates the proposed rule change as operative upon filing with the Commission.
At any time within 60 days of the filing of the 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.
