###### Securities and Exchange Commission

          - [Release No. 34-60338; File No. SR-CBOE-2009-051]

                    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”),[1]                                          and Rule 19b-4 thereunder,[2]                                          notice is hereby given that on July 16, 2009, the Chicago Board Options Exchange, Incorporated (“Exchange” or “CBOE”) filed with the Securities and Exchange Commission (“Commission”)                           ( print page 36804)                        the proposed rule change as described in Items I and II below, which Items have been prepared by the Exchange. The Exchange filed the proposal as a “non-controversial” proposed rule change pursuant to Section 19(b)(3)(A)(iii) of the Act [3]                                          and Rule 19b-4(f)(6) thereunder,[4]                                          which renders the proposed rule change effective upon filing with the Commission. 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 extend two pilot programs related to the Exchange's Automated Improvement Mechanism. The text of the proposed rule change is available on the Exchange's Web site (                    *http://www.cboe.org/​Legal*), at the Exchange's Office of the Secretary, and at the Commission.                

## 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

                    In February, 2006, CBOE obtained approval of a filing adopting the AIM auction process.[5]                                          AIM exposes certain orders electronically to an auction process to provide such orders with the opportunity to receive an execution at an improved price. The AIM auction is available only for orders that an Exchange member represents as agent and for which a second order of the same size as the “Agency Order” (and on the opposite side of the market) is also submitted (effectively stopping the Agency Order at a given price).                

                    Two components of AIM were approved on a pilot basis: (1) that there is no minimum size requirement for orders to be eligible for the auction, and (2) that the auction will conclude prematurely anytime there is a quote lock on the Exchange pursuant to Rule 6.45A(d).[6]                                          In connection with the pilot programs, the Exchange has submitted to the Commission reports providing detailed AIM auction and order execution data. In July 2006, the Exchange extended the pilot program until July 18, 2007.[7]                                          In July 2007, the Exchange extended the pilot program until July 18, 2008.[8]                                          In July 2008, the Exchange extended the pilot program until July 18, 2009.[9]                                          The proposed rule change merely extends the duration of the pilot programs until July 17, 2010. Extending the pilots for an additional year will allow the Commission more time to consider the impact of the pilot programs on AIM order executions.                

#### 2. Statutory Basis

                    The Exchange believes the proposed rule change is consistent with Section 6(b) of the Act in general [10]                                          and furthers the objectives of Section 6(b)(5) [11]                                          in particular in that by allowing the Commission additional time to evaluate the AIM pilot programs, it should serve to remove impediments to and perfect the mechanism of a free and open market and a national market system, and protect investors and the public interest.                

### B. Self-Regulatory Organization's Statement on Burden on Competition

CBOE 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

The Exchange neither solicited nor received comments on the proposal.

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

                    Because the foregoing proposed rule change: (1) Does not significantly affect the protection of investors or the public interest; (2) does not impose any significant burden on competition; and (3) by its terms does not become operative for 30 days after the date of this filing, 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) [12]                                          of the Act and Rule 19b-4(f)(6) thereunder.[13] 

                    A proposed rule change filed under Rule 19b-4(f)(6) normally may not become operative prior to 30 days after the date of filing. However, Rule 19b-4(f)(6)(iii) permits the Commission to designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange requests that the Commission waive the 30-day operative delay, which would make the rule change operative 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 AIM pilot programs to continue without interruption.[14]                                          Accordingly, the Commission designates the proposed rule change operative upon filing with the Commission.                

                    At any time within 60 days of the filing of such 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.                          ( print page 36805)
