May 11, 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 May 1, 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, II and III 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 establish a direct market data product, PHLX Depth of Market. PHLX Depth of Market is a data feed that will include full depth of quotes and orders, imbalance information and last sale data for options listed on PHLX.
The text of the proposed rule change is available on the Exchange's Web site at http://www.nasdaqtrader.com/micro.aspx?id=PHLXRulefilings, at the principal office of the Exchange, 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 the Statutory Basis for, the Proposed Rule Change
The purpose of the proposed rule change is to establish the PHLX Depth of Market data product. PHLX Depth of Market is a data product that provides: (i) Order and quotation information for individual quotes and orders on the PHLX book; (ii) last sale information for trades executed on PHLX; and (iii) an Imbalance Message, as described below.
The Imbalance Message includes the symbol, side of the market, size of matched contracts, size of the imbalance, and price of the affected series.
The Imbalance Message should enable PHLX Depth of Market subscribers to participate effectively in the PHLX Opening Process 
by providing them with information during the Opening Process when there is an opening imbalance.
PHLX Depth of Market is the equivalent of, and is based on, the NASDAQ ITCH to Trade Options or “ITTO” data feed that NASDAQ offers under NASDAQ Options Market (“NOM”) Rules, Chapter VI, Section 1(a)(3)(A).
As with ITTO, subscribers would use PHLX Depth of Market to “build” their view of the PHLX book by adding individual orders that appear on the feed, and subtracting individual orders that are executed.
The Exchange will establish monthly fees for the PHLX Depth of Market data product by way of a separate proposed rule change, which the Exchange will submit after the PHLX Depth of Market product is established.
PHLX Depth of Market provides data that should enhance the ability to analyze market conditions, and to create and test trading models and analytical strategies. The Exchange believes that PHLX Depth of Market is a valuable tool that can be used to gain comprehensive insight into the trading activity in a particular option series.
2. Statutory Basis
The Exchange 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 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, by establishing a market data product that enhances subscribers' ability to make decisions on trading strategy, and by providing data to facilitate such decisions in a timely manner.
The Exchange represents that it will make the PHLX Depth of Market data product equally available to any market participant that wishes to subscribe to it.
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 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
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 19(b)(3)(A) of the Act 
and Rule 19b-4(f)(6) 
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. If the Commission takes such action, the Commission shall institute proceedings to determine whether the proposed rule should be approved or disapproved.
IV. Solicitation of Comments
