###### Securities and Exchange Commission

          - [Release No. 34-57752; File No. SR-CBOE-2008-51] 

                    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 April 30, 2008, the Chicago Board Options Exchange, Incorporated (“Exchange” or “CBOE”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I and II below, which Items have been substantially 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]                                          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 CBOE rules to lower the appointment cost for options on the Standard & Poor's 500 (SPX). 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'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 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 purpose of this rule change is to amend CBOE Rule 8.3 to lower the appointment cost for SPX options. Presently, SPX has an appointment cost of 1.0. CBOE proposes to reduce the appointment cost to .95 effective May 1, 2008. Members then could utilize the excess membership capacity of .05 to hold an appointment and quote electronically in an appropriate number of Hybrid 2.0 option classes, which promotes competition and efficiency. 

#### 2. Statutory Basis 

                    The Exchange believes the proposed rule change is consistent with the Act and the rules and regulations under the Act applicable to a national securities exchange and, in particular, the requirements of Section 6(b) of the Act.[5]                                          Specifically, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) Act [6]                                          requirements that the rules of an exchange be designed to promote just and equitable principles of trade, to prevent fraudulent and manipulative acts and, in general, to 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 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 

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 rule 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 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, provided that the self-regulatory organization has given the Commission written notice of its intent to file the proposed rule change at least five business days prior to the date of filing of the proposed rule change or such shorter time as designated by the Commission,[7]                                          the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act [8]                                          and Rule 19b-4(f)(6) thereunder.[9]                                          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.                 

                    Under Rule 19b-4(f)(6) of the Act,[10]                                          the proposal does not become operative for 30 days after the date of its filing, or such shorter time as the Commission may designate if consistent with the protection of investors and the public interest. The Exchange has requested that the Commission waive the 30-day operative delay, so that the proposal may take effect on May 1, 2008. Lowering the appointment cost on SPX options will allow Market-Makers who have an appointment in SPX additional options classes in which they could act as Market-Makers. Thus, the Exchange believes that waiving the 30-day operative period will promote competition and efficiency without undue delay. The Commission agrees and, consistent with the protection of investors and the public interest, has determined to waive the 30-day                           ( print page 25814)                        operative delay so that the proposal may take effect on May 1, 2008.[11]
