E7-19162. Self-Regulatory Organizations; Chicago Board Options Exchange, Incorporated; Notice of Filing and Immediate Effectiveness of a Proposed Rule Change To Amend Its Obvious Error Rules

September 21, 2007.

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 September 13, 2007, the Chicago Board Options Exchange, Incorporated (“CBOE” 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 substantially prepared by the Exchange. CBOE has designated this proposal as one concerned solely with the administration of the Exchange under Section 19(b)(3)(A)(iii) of the Act ^[3] and Rule 19b-4(f)(3) thereunder,^[4] which renders the proposal 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 amend CBOE Rules 6.25 and 24.16, which are the Exchange's rules applicable to the nullification and adjustment of transactions. The text of the proposed rule change is available at the Exchange, the Commission's Public Reference Room, and http://www.cboe.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 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. CBOE has substantially 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

Under CBOE's obvious error rules, Trading Officials render certain determinations regarding the nullification and adjustment of transactions. The term “Trading Officials” is currently defined to mean two Exchange members designated as Floor Officials and one member of the Exchange's trading floor liaison (“TFL”) staff. The Exchange states that the purpose of the proposed rule change is to replace the reference to the “TFL staff” with a reference to the “Exchange's staff designated to perform Trading Official functions.” The Exchange is proposing to make the change at this time because it recently determined to reassign the Trading Official function from the CBOE TFL group to a group of designated Exchange personnel within CBOE's market control center. In trying to accommodate the reassignment, the Exchange believes a better approach than making a specific reference to a particular Exchange staff group is to make reference to the “Exchange's staff designated to perform Trading Official functions.” In this way, the Exchange would have the flexibility to delegate the Trading Official authorities under the obvious error rules to the appropriate Exchange staff and would not have to make a rule change merely, for instance, to accommodate a future change in the title of a staff group or to accommodate the reassignment of the authority to another staff group. The Exchange believes that because the authority exercised by Exchange staff is delegated pursuant to Exchange rules, the title of the particular group exercising their authority should not be relevant.

2. Statutory Basis

The Exchange believes that the proposed rule change is consistent with Section 6(b) of the Act ^[5] in general, and furthers the objectives of Section 6(b)(5) of the Act ^[6] in particular, in that it is designed to promote just and equitable principles of trade, foster cooperation among persons engaged in facilitating securities transactions, and protect investors and the public interest. The Exchange believes that this proposal complies with the Act because the Exchange is amending its rules to update and/or generalize references to certain Exchange staff in order to facilitate compliance.

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

The foregoing proposed rule change has been designated as concerned solely with the administration of the Exchange pursuant to Section 19(b)(3)(A)(iii) of the Act ^[7] and Rule 19b-4(f)(3) ^[8] thereunder. Accordingly, the proposal will take effect 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 proposed 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.
