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

1. Purpose

NYSE Amex LLC (“NYSE Amex” or the “Exchange”) is proposing to amend NYSE Amex Equities Rules 15 and 123C regarding the operation of its Order Imbalance Information service to: (1) Modify the reference price at which the Exchange reports the Order Imbalance Information; and (2) clarify what information is included and excluded from the Order Imbalance Information reports.

The Exchange notes that parallel changes are proposed to be made to the rules of the New York Stock Exchange LLC.

a. Background

By Notice dated April 9, 2009, NYSE Amex implemented the NYSE Amex Order Imbalance Information Data Product. NYSE Amex maintains an Order Imbalance Information datafeed of real-time order imbalances that accumulate prior to the opening of trading on the Exchange and prior to the close of trading on the Exchange. These orders are subject to execution at the market's opening or closing price, as the case may be, and represent issues that are likely to be of particular trading interest at the opening or closing.

The Exchange distributes information about these imbalances in real-time at specified intervals prior to the opening and closing auctions. The Exchange currently makes order imbalance information available at the following intervals.

For opening Order Imbalance Information:

• Every five minutes between 8:30 a.m. EST and 9 a.m. EST.
• Every one minute between 9 a.m. EST and 9:20 a.m. EST.
• Every 15 seconds between 9:20 a.m. EST and the opening (or 9:35 a.m. EST if the opening is delayed).

For closing Order Imbalance Information:

• Every fifteen seconds between 3:40 p.m. EST and 3:50 p.m. EST.
• Every five seconds between 3:50 p.m. EST and 4 p.m. EST.

Reference Price

The NYSE Amex Order Imbalance Information service currently uses the last sale price as the reference price for the Order Imbalance Information. In the case of opening order imbalances, this means the last sale price at the end of the prior trading day. For closing order imbalances, the reference price is equal to the last sale price.

Orders Included in NYSE Amex Order Imbalance Reports

The NYSE Amex Order Imbalance Information service provides the following information:

(A) In the case of the pre-opening datafeed, all interest eligible to trade in the opening transactions excluding odd-lot orders and the odd-lot portion of partial round-lot orders. Floor broker interest includes all interest except non-displayed reserve interest marked “Do Not Display” (“DND”). Customer interest includes all interest except for non-displayed reserve interest. DMM interest is not included in the pre-opening datafeed.

(B) In the case of pre-closing datafeed, all market-on-close orders and limit-on-close orders eligible to participate in the closing transaction. It excludes odd-lot orders, the odd-lot portion of partial round-lot orders, DMM interest and Crowd interest.

b. Proposed Amendments

Reference Price

In order to provide the most accurate imbalance information, the Exchange proposes to modify what constitutes the reference price for the dissemination of the NYSE Amex Order Imbalance Information feed. Prior to the opening transaction, if a pre-opening indication is published pursuant to the provisions of NYSE Amex Equities Rule 15 (“Pre-Opening Indications”) paragraphs (a) and (b), or in the event of a mandatory publication pursuant to NYSE Amex Equities Rule 123D (“Openings and Halts in Trading”), the reference price will no longer be the closing price of the prior trading day.

The Exchange proposes to have the reference price equal the last sale (previous closing price) or the price indication published under the Rule 15 or 123D. Therefore, when the Exchange publishes a pre-opening indication in a security pursuant to the provisions of paragraphs (a) and (b) of NYSE Amex Equities Rule 15 or NYSE Amex Equities Rule 123D, the reference price will be determined as follows:

• If the Bid Price from the indication (the lower price) is higher than the last sale, the Reference Price will be the Bid.
• If the Offer Price from the indication (the higher price) is lower than the last sale, the Reference Price will be the Offer.
• If the Last Sale is within the indication range, the Book shall use the Last Sale as the Reference Price
• If multiple indications have been published, the last indication that the Exchange makes available shall be used as the Reference Price.

Examples:

(1) XYZ security closed at a price of $15.00 on April 1, 2009. On April 2, 2009, the Exchange publishes a pre-opening indication for XYZ with a bid price of $16.00 and an offer price of $16.50. The reference price for the NYSE Order Imbalance datafeed in XYZ security on April 2, 2009 will be $16.00.

(2) XYZ security closed at a price of $15.00 on April 1, 2009. On April 2, 2009, the Exchange publishes a pre-opening indication for XYZ with a bid price of $14.00 and an offer price of $14.50. The reference price for XYZ data feed on April 2, 2009 will be $14.50.

(3) XYZ security closed at a price of $15.00 on April 1, 2009. On April 2, 2009, the Exchange publishes pre-opening indication for XYZ with a bid price of $14.99 and an offer price of $15.02. The reference price for XYZ data feed on April 2, 2009 will be $15.00.

In the case of pre-closing imbalances, the NYSE Amex Order Imbalance Information service also uses the last sale price as the reference price for pre-closing Order Imbalance Information that it disseminated pursuant to NYSE Amex Equities Rule 123C (“Market on the Close Policy and Expiration Procedures”).

The Exchange proposes to modify what it uses as the reference price when the last sale price does not fall within the best bid and the best offer on the Exchange at the time that the Exchange calculates a closing imbalance for a security, as follows:

• If the last sale price is lower than the Bid price, then the Bid Price will serve as the Reference Price.
• If the last sale price is higher than the Offer Price, then the Offer Price will serve as the Reference Price.
• If the last sale price falls within the Exchange's best bid and offer for the security, the last sale price will serve as the Reference Price.

Examples:

(1) The sale in XYZ security prior to the dissemination of the order imbalance feed was at a price of $15.00. The quote prior to the dissemination of the datafeed is 100 shares bid at a price of $15.02 and 500 shares offered at a $15.20. The reference price for the NYSE Order Imbalance datafeed in XYZ security will be $15.02.

(2) The sale in XYZ security prior to the dissemination of the order imbalance feed was at a price of $15.00. The quote prior to the dissemination of the datafeed is 100 shares bid at a price of $14.91 and 500 shares offered at a $14.99. The reference price for the NYSE Order Imbalance datafeed in XYZ security will be $14.99.

(3) The sale in XYZ security prior to the dissemination of the order imbalance feed was at a price of $15.00. The quote prior to the dissemination of the datafeed is 100 shares bid at a price of $14.98 and 500 shares offered at a $15.02. The reference price for the NYSE Order Imbalance datafeed in XYZ security will be $15.00.

The Exchange believes that the amendments to the reference price for the publication of the NYSE Amex Order Imbalance Information service will enhance the value of the product by providing the user with a more accurate depiction of the market interest available in the security.

Orders Included in NYSE Amex Pre-Opening Order Imbalance Information Reports

The Exchange proposes to add all DMM s-quote interest eligible for execution in the opening transaction, at no additional charge, to the order information currently included in the pre-opening NYSE Amex Order Imbalance Information Reports. DMM s-quote interest is currently eligible for execution in the opening transaction but is not included in the Order Imbalance Information Report. The Exchange believes that the addition of DMM s-quote interest to the Order Imbalance Information Report will enhance the value of this product by including additional information about the electronic interest eligible to trade at the opening.

2. Statutory Basis

The bases under the Securities Exchange Act of 1934 (the “1934 Act”) for this proposed rule change are the requirements under Section 6(b)(5) that the rules of an exchange be designed 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 proposal benefits investors by modifying NYSE Amex Order Imbalance Information to provide investors with a more accurate depiction of the market and additional information on the open for a security.

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

Because the foregoing proposed rule change: (i) Does not significantly affect the protection of investors or the public interest; (ii) does not impose any significant burden on competition; and (iii) 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.

The Exchange has requested that the Commission waive the 30-day operative delay so that the proposal may become operative immediately upon filing in order to immediately provide market participants with the most accurate supplemental market information prior to the execution of the opening and closing transactions on the Exchange. The Commission believes such waiver is consistent with the protection of investors and the public interest. Accordingly, the Commission designates the proposed rule change 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.
