E7-14505. Self-Regulatory Organizations; Chicago Board Options Exchange, Incorporated; Notice of Filing and Immediate Effectiveness of a Proposed Rule Change Relating to the Extension of the Customer Portfolio Margin Pilot Program

July 19, 2007.

Pursuant to section 19(b)(1) of the Securities Exchange Act of 1934 (“Act” or “Exchange Act”) ^[1] and Rule 19b-4 thereunder,^[2] notice is hereby given that on June 29, 2007, 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 CBOE. CBOE has filed the proposed rule as a “non-controversial” proposed rule change pursuant to section 19(b)(3)(A) of the Act ^[3] and Rule 19b-4(f)(6) 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

CBOE proposes to extend an existing customer portfolio margining pilot program (“Pilot Program”) through July 31, 2008. The Pilot Program is codified in CBOE Rules 12.4, 9.15(c), 13.5 and 15.8A. There is no change to the rule text in conjunction with this proposed rule change. The text of the proposed rule change is available on CBOE's Web site (http://www.cboe.org/​legal), at CBOE's principal office, 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, CBOE 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 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 the Statutory Basis for, the Proposed Rule Change

1. Purpose

The Pilot Program, as previously approved by the Commission, allows broker-dealers, for eligible securities, to compute customer margin requirements based on a portfolio margining methodology.

The purpose of the proposed rule change is to extend the Pilot Program for a twelve-month period, commencing on August 1, 2007, through July 31, 2008. The existing Pilot Program expires on July 31, 2007. The Exchange believes that extending the Pilot Program for twelve months is warranted in that time is needed to assess the operation of the rules, especially in light of the fact that amendments to the rule effective April 2, 2007, made equities, equity options, narrow-based index options, unlisted derivatives and security futures eligible for portfolio margining.^[5] CBOE has not encountered any problems or difficulties relating to the Pilot Program since its inception. For these reasons and the reasons cited in the Pilot Adoption Filing, CBOE requests that the Commission extend the Pilot Program through July 31, 2008. CBOE proposes to make the proposed rule change operative on July 31, 2007.

2. Statutory Basis

CBOE believes that the proposed rule change is consistent with the section 6(b) of the Act,^[6] in general, and furthers the objectives of section 6(b)(5) ^[7] of the Act, in particular, because it is designed to promote just and equitable principles of trade, to prevent fraudulent and manipulative acts and practices, 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

Because the foregoing 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 prior to 30 days after the date of filing, or such shorter time as the Commission may designate, it 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.
