Self-Regulatory Organizations; Chicago Board Options Exchange, Incorporated; Notice of Filing and Immediate Effectiveness of Proposed Rule Change To Amend CBOE's Rules Related To Credit Default Options

Pursuant to section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”), and Rule 19b-4 thereunder, notice is hereby given that on July 16, 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, II, and III below, which Items have been prepared substantially by the Exchange. The Exchange has designated the proposed rule change as one constituting a stated policy, practice, or interpretation with respect to the meaning, administration, or enforcement of an existing rule under section 19(b)(3)(A)(i) of the Act and Rule 19b-4(f)(1) thereunder, 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 its rules pertaining to Credit Default Options (“CDOs”) in order to set out certain parameters that the Exchange intends to use for determining the applicable share to be allocated to a Successor Reference Entity if there is a CDO contract adjustment due to a Succession Event. The text of the proposed rule change is available on the Exchange's Web site ( http://www.cboe.org/legal ), at the Exchange'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, 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 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 Exchange recently received approval to list and trade Credit Default Options or CDOs, which are binary call options based on Credit Events in one or more debt securities of an issuer or guarantor. The Exchange is now proposing to amend Rule 29.4, Adjustments, in order to set out certain parameters that the Exchange intends to use for determining the applicable share to be allocated to a Successor Reference Entity if there is a CDO contract adjustment due to a Succession Event.

By way of background, the cash settlement amount for a CDO is generally $100,000 per contract (equal to an exercise settlement value of $100 multiplied by a contract multiplier of 1,000) upon automatic exercise if the Exchange confirms a Credit Event. If a Credit Event is not confirmed, the cash settlement value will be $0. Among other things, Rule 29.4 provides that CDO contracts will be subject to adjustment and replaced by one or more CDOs derived from Successor Reference Entities based on the applicable share of each Successor Reference Entity. The “applicable share” is a percentage amount used to determine the adjusted cash settlement amount and adjusted contract multiplier applicable to each replacement CDO. For example, if there are two Successor Reference Entities that each have an applicable share of 50%, the cash settlement amount for each replacement CDO would be $50,000 (equal to an exercise settlement value of $100 multiplied by the revised contract multiplier of 500).

Currently, the rule is silent regarding the calculation of the applicable share. Based on feedback from potential CDO investors and in order to provide more clarity and certainty to such investors, the Exchange is proposing to codify certain parameters that it intends to utilize in determining the applicable share. As set out in the proposed revisions to the rule text, in determining the applicable share the Exchange, as a general rule, would allocate an equal share to each Successor Reference Entity that has succeeded the Reference Entity as issuer and guarantor of (i) at least one Relevant Obligation and (ii) at least 25% of the principal amount of the original Reference Entity's outstanding debt obligations other than non-recourse indebtedness. If no Successor Reference Entity satisfies the “at least 25%” requirement and the original Reference Entity does not survive following the Succession Event, an equal share will be allocated to the Successor Reference Entity(ies) that succeeded to the largest percentage of the original Reference Entity's outstanding debt obligations other than non-recourse indebtedness. These applicable share parameters would override any contradictory provision in the Relevant Obligation(s) terms. In addition, the Exchange intends to apply these parameters to all presently listed and any future-listed CDO contracts.

The following examples illustrate the application of the parameters:

• Assume a Succession Event is confirmed by the Exchange in a Reference Entity with $100 million outstanding in debt obligations and, under the terms of the Succession Event, Successor Reference Entity A succeeds to certain Relevant Obligations and other debt obligations totaling $40 million (40% of the original Reference Entity's outstanding debt obligations), Successor Reference Entity B succeeds to certain Relevant Obligations and other debt obligations totaling $30 million (30%), and Successor Reference Entity C succeeds to all other Relevant Obligations and other debt obligations totaling $30 million (30%). A CDO contract overlying Relevant Obligations on the original Reference Entity would be adjusted and replaced with three new CDOs, one each for Successor Reference Entities A, B and C, and each having an equal share value equivalent to 33.333%, the “applicable share,” of the original CDO contract (e.g., 33.333% of $100,000, or $33,333, which is equal to an exercise settlement value of $100 multiplied by the revised contract multiplier of 333.33).
• Assume a Succession Event is confirmed by the Exchange in a Reference Entity with $100 million outstanding in debt obligations and, under the terms of the Succession Event, Successor Reference Entity A succeeds to certain Relevant Obligations and other debt obligations totaling $45 million (45% of the original Reference Entity's outstanding debt obligations), Successor Reference Entity B succeeds to certain Relevant Obligations and other debt obligations totaling $40 million (40%), and Successor Reference Entity C succeeds to all other Relevant Obligations and other debt obligations totaling $15 million (15%). A CDO contract overlying Relevant Obligations on the original Reference Entity would be adjusted and replaced with two new CDOs, one each for Successor Reference Entities A and B, and each having an equal share value equivalent to 50% of the original CDO contract (e.g., 50% of $100,000, or $50,000, which is equal to an exercise settlement value of $100 multiplied by the revised contract multiplier of 500). Successor Reference Entity C's applicable share would be 0.
• Assume a Succession Event is confirmed by the Exchange in a Reference Entity with $100 million outstanding in debt obligations and, under the terms of the Succession Event, Successor Reference Entities A and B each succeed to certain Relevant Obligations and other debt obligations totaling $23 million each (23% of the original Reference Entity's outstanding debt obligations) and Successor Reference Entities C, D and E each succeed to certain Relevant Obligations and other debt obligations totaling $18 million each (18%). A CDO contract overlying Relevant Obligations on the original Reference Entity would be adjusted and replaced with two new CDOs, one each for Successor Reference Entities A and B, and each having an equal share value equivalent to 50% of the original CDO contract (e.g., 50% of $100,000, or $50,000, which is equal to an exercise settlement value of $100 multiplied by the revised contract multiplier of 500). Successor Reference Entities C, D and E's applicable shares would be 0.

As indicated above, the Exchange is proposing to codify these parameters for determining the applicable share of each Successor Reference Entity based on feedback we have received thus far from potential CDO investors. The Exchange believes that setting forth these parameters would clarify how the Exchange intends to administer the Succession Event confirmation process, thereby affording investors additional clarity and certainty regarding the impact of a Succession Event on an outstanding CDO contract. The Exchange also understands that these parameters would be substantially similar to and generally consistent with the practice in the over-the-counter market.

Finally, the Exchange is also proposing a non-substantive change to Rule 29.4. Specifically, the Exchange is substituting the phrase “the adjusted cash settlement amount(s) and the adjusted contract multiplier(s)” for “adjusted unit of trading and the adjusted exercise price” in paragraph (c) to be consistent with the use and meaning of those terms elsewhere in the rule text.

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 national securities exchanges. Specifically, the Exchange believes the proposed rule change is consistent with the section 6(b)(5) which requires that the rules of an exchange be designed to promote just and equitable principles of trade, to prevent fraudulent and manipulative acts, to remove impediments to and to perfect the mechanism for a free and open market and a national market system, and, in general, to protect investors and the public interest. As indicated above, the Exchange believes that setting forth the “applicable share” parameters would clarify how the Exchange intends to administer the Succession Event confirmation process, thereby affording investors additional clarity and certainty regarding the impact of a Succession Event on an outstanding CDO contract.

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 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 change constitutes a stated policy, practice, or interpretation with respect to the meaning, administration, or enforcement of an existing rule, it has become effective pursuant to section 19(b)(3)(A)(i) of the Act and Rule 19b-4(f)(1) thereunder. At any time within 60 days of the filing of the 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.
