E6-7470. Self Regulatory Organizations; Chicago Stock Exchange, Inc.; Notice of Filing and Immediate Effectiveness of Proposed Rule Change Relating to Participant Fees and Credits.

May 10, 2006.

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 April 24, 2006, the Chicago Stock Exchange, Inc. (“CHX” or “Exchange”) filed with the Securities and Exchange Commission (the “Commission”) the proposed rule change as described in Items I, II and III below, which Items have been prepared by the CHX. 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 CHX proposes to amend its Participant Fee Schedule (the “Fee Schedule”) to reduce the assignment fees charged to specialist firms seeking the right to trade securities to $500 per assignment, when the securities are assigned in competition with other firms. The text of this proposed rule change is available on the Exchange's Web site at http://www.chx.com/​rules/​proposed_​rules.htm and in 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 CHX included statements concerning the purpose of and basis for the proposed rule change and discussed any comments it received regarding the proposed rule change. The text of these statements may be examined at the places specified in Item IV below. The CHX 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 Changes

1. Purpose

Under the Exchange's rules, the Committee on Specialist Assignment and Evaluation is responsible for appointing participant firms to act as specialists on the Exchange.^[3] When more than one firm competes for the right to be the specialist in a particular security, the Exchange charges assignment fees of $1,000 or $4,000 for the assignment, depending on the number of firms competing for that right.^[4]

In a separate filing, the Exchange has submitted a proposal to implement a new trading model, which features an automated Matching System into which orders may be sent for execution, but which does not involve the use of specialists to handle customer orders.^[5] Instead, in this new model, off-Exchange market makers may choose to handle customer orders, by sending those orders to the Exchange or to other venues for execution. Because the Exchange plans to be able to implement its new model in the second quarter of 2006, the Exchange believes that the right to trade securities as an Exchange specialist has only a short-term benefit. For that reason, the Exchange proposes to reduce the assignment fees to $500 per security, regardless of the number of participants competing for the assignments and regardless of the type of security that is being assigned.^[6]

2. Statutory Basis

The Exchange believes that the proposed rule change is consistent with Section 6(b)(4) of the Act ^[7] in that it provides for the equitable allocation of reasonable dues, fees and other charges among its members and creates an appropriate (and limited) incentive for a firm to agree to act as specialist on a temporary basis.

B. Self-Regulatory Organization's Statement of Burden on Competition

The Exchange does not believe that the proposed rule changes will impose any burden on competition.

C. Self-Regulatory Organization's Statement on Comments Regarding the Proposed Rule Changes Received From Members, Participants or Others

No written comments were either solicited or received.

III. Date of Effectiveness of the Proposed Rule Changes and Timing for Commission Action

The foregoing rule change establishes or changes a due, fee or other charge imposed by the Exchange and therefore has become effective pursuant to Section 19(b)(3)(A) of the Act ^[8] and subparagraph (f)(2) of Rule 19b-4 thereunder.^[9] At any time within 60 days of the filing of such 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 purpose of the Act.

IV. Solicitation of Comments

4.  For “dual trading system” securities, a group of securities which includes securities listed on the New York Stock Exchange or American Stock Exchange, the Exchange currently charges a $1,000 assignment fee if the security (or a group of securities) was assigned in competition with at least one other participant and up to one-third of all participants that trade these issues. The fee for the assignment of this type of security is increased to $4,000 if the security (or a group of securities) was assigned in competition with more than one-third of the participants that trade these issues. For Nasdaq/NM securities, the Exchange currently charges a $1,000 assignment fee if the security was assigned in competition with one other participant firm; the fee is increased to $4,000 if two or more firms compete for the assignment.

5.  See SR-CHX-2006-05.

6.  The Exchange believes that it is appropriate to maintain at least a $500 assignment fee to help defray the costs of the assignment process. The Exchange will continue to charge no fee when securities are assigned without competition. The Exchange is submitting a separate filing, SR-CHX-2006-13, which proposes to make this fee reduction effective retroactively to March 1, 2006.
