Self-Regulatory Organizations; Chicago Board Options Exchange, Incorporated; Notice of Filing and Immediate Effectiveness of Proposed Rule Change and Amendment No. 1 Thereto Relating to the Establishment of a Pilot Program That Increases Position and Exercise Limits for Options on the iShares® Russell 2000® Index Fund

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 January 22, 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 and II below, which Items have been substantially prepared by CBOE. On January 22, 2007, CBOE submitted Amendment No. 1 to the proposed rule change. CBOE has filed the proposal pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6) 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, as amended, from interested persons.

I. Self-Regulatory Organization's Statement of the Terms of Substance of the Proposed Rule Change

CBOE proposes to amend Rule 4.11 to exempt options on the iShares® Russell 2000® Index Fund (“IWM”) from the position and exercise limits provided for under the Rule 4.11 Pilot Program and to increase the standard position and exercise limits for IWM as part of a six-month pilot (“Rule 4.11 IWM Pilot Program”). The text of the proposed rule change is available at CBOE, 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, 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 Statutory Basis for, the Proposed Rule Change

1. Purpose

The Exchange proposes to amend Interpretation and Policy .07 to Rule 4.11 on a six-month pilot basis to exempt options on IWM from the Rule 4.11 Pilot Program. Under the Rule 4.11 Pilot Program, the position and exercise limits for IWM would be reduced on January 22, 2007 from 500,000 to 250,000 contracts. The Exchange now proposes to allow position and exercise limits for options on IWM to remain at 500,000 contracts on a pilot basis, from January 22, 2007 through July 22, 2007.

In June 2005, as a result of a 2-for-1 stock split, the position limit for IWM options was temporarily increased from 250,000 contracts (covering 25,000,000 shares) to 500,000 contracts (covering 50,000,000 shares). At the time of the split, the furthest IWM option expiration date was January 2007. Therefore, the temporary increase of the IWM position limit will revert to the pre-split level (as provided for in connection with the Rule 4.11 Pilot Program) of 250,000 contracts after expiration in January 2007, or on January 22, 2007.

The Exchange believes that a position limit of 250,000 contracts is too low and may be a deterrent to the successful trading of IWM options. Importantly, options on IWM are 1/10th the size of options on the Russell 2000® Index (“RUT”), which have a position limit of 50,000 contracts. Traders who trade IWM options to hedge positions in RUT options are likely to find a position limit of 250,000 contracts in IWM options too restrictive and insufficient to properly hedge. For example, if a trader held 50,000 RUT options and wanted to hedge that position with IWM options, the trader would need—at a minimum-500,000 IWM options to properly hedge the position. Therefore, the Exchange believes that a position limit of 250,000 contracts is too low and may adversely affect market participants' ability to provide liquidity in this product.

Additionally, IWM options have grown to become one of the largest options contracts in terms of trading volume. For example, the volume in options on IWM set a new single-day record on June 8, 2006, when 760,803 contracts (120,229 calls and 640,574 puts) traded on that day. This record level volume beat the previous single-day high of 727,521 contracts on May 17, 2006. Further, over the previous six months, the average daily CBOE trading volume of IWM options has been 187,190 contracts and a total of 23,960,382 contracts have traded on the Exchange.

As a result, the Exchange proposes that options on IWM be subject to position and exercise limits of 500,000 contracts on a pilot basis to run from January 22, 2007 through July 22, 2007. The Exchange believes that increasing position and exercise limits for IWM options will lead to a more liquid and more competitive market environment for IWM options that will benefit customers interested in this product.

The Exchange would require that each member or member organization that maintains a position on the same side of the market in excess of 10,000 contracts in the IWM option class, for its own account or for the account of a customer report certain information. This data would include, but would not be limited to, the option position, whether such position is hedged and if so, a description of the hedge, and if applicable, the collateral used to carry the position. Exchange market-makers (including DPMs) would continue to be exempt from this reporting requirement as market-maker information can be accessed through the Exchange's market surveillance systems. In addition, the general reporting requirement for customer accounts that maintain a position in excess of 200 contracts will remain at this level for IWM options.

2. Statutory Basis

CBOE believes that the proposed rule change is consistent with and furthers the objectives of Section 6(b)(5) of the Act, in that it is designed to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, 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 forgoing rule change does not: (1) Significantly affect the protection of investors or the public interest; (2) impose any significant burden on competition; and (3) become operative for 30 days after the date of this filing, or such shorter time as the Commission may designate, it has become effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6) thereunder.

A proposed rule change filed under 19b-4(f)(6) normally may not become operative prior to 30 days after the date of filing. However, Rule 19b-4(f)(6)(iii) permits the Commission to designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has requested that the Commission waive the 30-day operative delay. The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest because such waiver would permit position and exercise limits for options on IWM to remain at 500,000 option contracts for a six-month pilot period. For this reason, the Commission designates the proposed rule change to be effective and operative 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 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.
