Self-Regulatory Organizations; New York Stock Exchange LLC; Notice of Filing of Proposed Rule Change Amending NYSE Rule 123C To Allow Exchange Systems To Provide Order Imbalance Information With Respect to Market At-The-Close and Marketable Limit At-the-Close Interest to Floor Brokers Beginning Two Hours and Until Fifteen Minutes Prior to the Scheduled Close of Trading on Every Trading Day

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 9, 2010, 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, II, and III below, which Items have been prepared by the self-regulatory organization. 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 amend proposes to amend [sic] NYSE Rule 123C (“The Closing Procedures”) to describe the manner in which Exchange systems provide order imbalance information to Floor brokers. The text of the proposed rule change is available at the Exchange, the Commission's Public Reference Room, and http://www.nyse.com.

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 self-regulatory organization 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 those 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 parts of such statements.

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

1. Purpose

The New York Stock Exchange LLC (“NYSE” or “Exchange”) proposes to amend NYSE Rule 123C(6) to specify that, beginning at 2:00 p.m. on every trading day, Floor brokers will receive an electronic communication from Exchange systems that provides the amount of, and any imbalance between, Market “At-The-Close” (“MOC”) interest and marketable Limit “At-The-Close” (“LOC”) interest to buy and MOC interest and marketable LOC interest to sell in certain securities. The MOC/LOC interest is executable only on the Close and is subject to cancellation at any time before 3:45 p.m.

Background

Pursuant to NYSE Rule 115 (“Disclosure of Orders by DMMs”), DMMs may, while acting in a market making capacity, provide information about buying or selling interest in the market, including (a) Aggregated buying or selling interest contained in Floor broker agency interest files other than interest the broker has chosen to exclude from the aggregated buying and selling interest, (b) aggregated interest of Minimum Display Reserve Orders and (c) the interest included in DMM interest files, excluding CCS interest as described in Rule 1000(c), in response to an inquiry from a member conducting a market probe in the normal course of business. Market probes assist Floor brokers in representing customer orders efficiently and effectively. There is no limitation in Rule 115 as to the number of market probes permitted during the trading day.

Historically, Floor brokers could only orally request a market probe from the specialist. As the NYSE evolved to a more automated trading venue, the Exchange and the Floor community endeavored to address an increase in the volume of market probes by Floor brokers to specialists in the afternoon hours leading up to the closing transaction. In May 2008, Exchange systems began electronically providing to Floor brokers, the amount of, and any imbalance between MOC interest and marketable LOC interest to buy and MOC interest and marketable LOC interest to sell in each security in which a Floor broker is representing an order or in any security that the Floor broker electronically requests such information. In March 2010, as part of changes to the Exchange's closing process, Exchange systems began decrementing the total imbalance between MOC interest and marketable LOC interest to buy and MOC interest and marketable LOC interest to sell by any Closing Offset Orders on the opposite side of the imbalance to calculate the imbalance (the “MOC/LOC imbalance information”). The dissemination of the MOC/LOC imbalance information to Floor brokers between 2:00 and 3:45 p.m. was deactivated on May 17, 2010. Floor brokers may still orally request and receive responses to market probes directly from DMMs.

Proposed Amendments to NYSE Rule 123C(6)

The Exchange proposes to amend NYSE Rule 123C(6) to state that, between 2 p.m. and 3:45 p.m. on any trading day (or two hours prior to the closing transaction until 15 minutes prior to the closing transaction on any day that the scheduled close of trading on the Exchange is earlier than 4 p.m.), Exchange systems shall automatically provide the MOC/LOC imbalance information to Floor brokers, approximately every 15 seconds, for any security in which the Floor broker is representing an order and in any security that the Floor broker specifically requests. Specific requests for information by Floor brokers will not carry over to the next trading day and must be re-entered on each trade date Floor brokers want to receive the information. Beginning at 3:45 p.m., Floor brokers may receive the Exchange's proprietary Order Information Imbalance datafeed pursuant to NYSE Rule 123C(6)(a)(iv). The Exchange provides the Order Information Imbalance datafeed to subscribers for a fee.

The Exchange's proposed dissemination of this MOC/LOC imbalance information is the electronic evolution of the market probe response that Floor brokers have always been entitled to receive and may otherwise orally request directly from DMMs. While a vast majority of the transactions executed on the Exchange are automated, Floor brokers play an important role for customers in those transactions that require the expertise of a professional trading floor agent. Providing the MOC/LOC imbalance information to Floor brokers is appropriate because a key component of their role as agent for these sophisticated customers is to provide market “color” to the extent permitted under applicable rules. The Exchange's electronic dissemination of this information would be limited to the Floor broker hand-held devices, which are unable to automatically forward or re-transmit the electronic datafeed to any other location, although Floor brokers are permitted to provide their customers with specific data points from the feed.

Finally, the Exchange proposes to correct erroneous rule text in 123C(6)(a)(v). The rule text incorrectly states that the dissemination of the Order Imbalance Datafeed commences 10 minutes prior to the scheduled close of trading on any day that the scheduled close of trading on the Exchange is earlier than 4 p.m. The 10 minute interval is a legacy time frame related to the Exchange's prior publication of imbalance at 3:40 p.m. and 3:50 p.m. When the Exchange moved to a single imbalance publication at 3:45 p.m., the rule text should have been modified to reflect that dissemination of the Order Imbalance Information on any day that the scheduled close was prior to 4 p.m. would commence approximately 15 minutes before the scheduled closing time consistent with the single imbalance publication. The Exchange therefore seeks to amend NYSE Rule 123C(6)(a)(v) accordingly.

2. Statutory Basis

The basis under the Act for the proposed rule change is the requirement under Section 6(b)(5), which requires that an exchange have rules that are designed 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 proposed rule change is consistent with these objectives in that the dissemination of MOC/LOC imbalance information would provide Floor brokers with an understanding of developing trends early enough to get appropriate direction from their customers and to know where on the physical Trading Floor it needs to deploy its brokers in preparation for the closing transaction. Overall, the Exchange believes that dissemination of MOC/LOC imbalance information to Floor brokers is consistent with the above objectives because it removes impediments to and perfects the mechanism of a free and open market through the efficient operation of the Exchange.

Dissemination of MOC/LOC imbalance information to Floor brokers would serve as an efficiency tool to enhance the Floor brokers' ability to meet their best execution obligations in the face of a dilemma that is unique to a physical Trading Floor, i.e., how to position resources so that they are in the correct place to execute orders on behalf of sophisticated customers whose needs are not effectively met by strictly electronic trading. While the imbalance information is important to Floor brokers in carrying out their obligations to those customers, the Exchange believes this information would not be material to market participants executing automated orders. In this regard, the Exchange believes it is appropriate to provide Floor brokers with specific types of information that is directly related to the unique functions they perform on the Trading Floor.

In this particular case, the Exchange believes that the dissemination of MOC/LOC information to Floor brokers would promote the efficient operation of the Exchange's market by reducing the frequency of time-consuming Floor broker oral market probes leading up to the closing transaction, thus affording DMMs more time to monitor trading. As trading has become more electronic, staffing on the trading Floor has declined, so that there are now fewer Floor brokers even as the number of listed securities has increased. Similarly, DMM units and individual DMMs on the Floor are managing trading in greater numbers of stocks than ever before. The need for DMMs to be focused on their assigned securities, particularly on high volume trading days, such as an Expiration Friday or an index rebalancing event, or trading days with high levels of market volatility, is critical to the maintenance of fair and orderly markets.

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 solicited or received with respect to the proposed rule change.

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