Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”),^[1] and Rule 19b-4 thereunder,^[2] notice is hereby given that on November 14, 2012, the Chicago Board Options Exchange, Incorporated (the “Exchange” or “CBOE”) filed with the Securities and Exchange Commission (the “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 correct a numbering error in CBOE Rule 12.3 that was unintentionally created. No substantive changes are proposed in this filing. 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

In SR-CBOE-2012-043, an error was inadvertently made to the numbering of Rule 12.3 (Margin Requirements).^[5] In that filing, the Exchange amended Rule 12.3 to provide for universal spread margin rules and, among other changes, subparagraph (e)(1)(C) was deleted in its entirety. Subparagraph (e)(1)(D) of Rule 12.3 remained unchanged however, and was mistakenly not renumbered to account for the deletion of the previous provision. The purpose of this filing is to correct this oversight and to re-number subparagraph (e)(1)(D) to subparagraph (e)(2). No substantive changes to CBOE rules are being made by this proposal.

2. Statutory Basis

The Exchange believes that the proposed rule change is consistent with Section 6(b) ^[6] of the Act and the rules and regulations under the Act, in general, and furthers the objectives of Section 6(b)(5),^[7] in particular, in that it is designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in facilitating transactions in securities, and to remove impediments to and perfect the mechanisms of a free and open market and a national market system, and, in general, to protect investors and the public interest. The proposed correction will protect investors and the public interest by eliminating potential confusion that could be caused by a numbering error in CBOE's rules.

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

Because the foregoing proposed rule change 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, it has become effective pursuant to Section 19(b)(3)(A) ^[8] of the Act and Rule 19b-4(f)(6)(iii) ^[9] thereunder.

A proposed rule change filed under Rule 19b-4(f)(6)^[10] normally does not become operative prior to 30 days after the date of filing. However, pursuant to Rule 19b-4(f)(6)(iii),^[11] the Commission may designate a shorter time if such action is consistent with the protection of investors and the public interest, provided that the Exchange has given the Commission written notice of its intent to file the proposed rule change, together with a brief description and text of the proposed rule change, at least five business days prior to the date of its filing. The proposed rule change corrects a numbering error in CBOE Rule 12.3 and does not present any substantive issues. Further, the Exchange satisfied the five day pre-filing requirement. Accordingly, the Commission believes that waiving the 30-day operative delays is consistent with the protection of investors and the public interest and, therefore, designates the proposed rule change as operative upon filing.

At any time within 60 days of the filing of this proposed rule change, the Commission summarily may temporarily suspend 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.
