          - [Release No. 34-55377; File No. SR-CBOE-2007-17] 

                    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 February 22, 2007, 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 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 

                    CBOE proposes to amend its rules relating to CBOE's determination to trade options on the S&P 100 (XEO) on the Hybrid 2.0 Platform. The text of the proposed rule change is available on CBOE's Web site (                    *www.cboe.org/​Legal*), at the CBOE'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 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 Statutory Basis for, the Proposed Rule Change 

#### 1. Purpose 

                    The purpose of this rule change is to amend CBOE Rule 8.3 and Rule 8.4 in connection with CBOE's determination to trade options on the S&P 100 (XEO) on the Hybrid 2.0 Platform.[5]                                          Presently, XEO and options on the S&P 100 (OEX) collectively have an appointment cost of 1.0. CBOE intends to “decouple” XEO from OEX for purposes of assigning an appointment cost when XEO trades on the Hybrid 2.0 Platform. On Hybrid 2.0, XEO's appointment cost will be .25 and XEO will be classified in Tier A+. In connection with this change, CBOE also proposes to amend OEX's appointment cost and assign it a cost of .75. OEX will continue to be classified as a Non-Hybrid option class. CBOE intends to trade XEO on the Hybrid 2.0 Platform beginning on March 1, 2007.                 

#### 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.[6]                                          Specifically, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) of the Act,[7]                                          which requires 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 

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 

                    The foregoing rule change has become effective pursuant to Section 19(b)(3)(A)(iii) of the Act [8]                                          and subparagraph (f)(6) of Rule 19b-4 [9]                                          thereunder because it does not: (i) Significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; (iii) become operative for 30 days from the date on which it was filed, or such shorter time as the Commission may designate; and the Exchange has given the Commission written notice of its intention to file the proposed rule change at least five business days prior to filing. 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 date, so that XEO options may begin trading on the Hybrid 2.0 platform on March 1, 2007. The Commission believes that the proposed rule change does not raise any new regulatory issues and, consistent with the protection of investors and the public interest, has determined to waive the 30-day operative date, so that XEO options may                           ( print page 10572)                        begin trading on the Hybrid 2.0 platform without delay.[11]
