[^2] 17 CFR 240. 19b-4.
[^3]*See* Securities Exchange Act Release No. 53441 (March 8, 2006), 71 FR 13642.
**II. Description of the Proposal**
The Exchange proposed to amend its rules to prohibit its participants from breaking customer orders into smaller multiple orders for the primary purpose of maximizing rebates or other payments to the participant without regard for the customer's interest.
**III. Discussion and Commission Findings**
The Commission has reviewed carefully the proposed rule change and finds that it is consistent with the requirements of the Act and the rules and regulations thereunder applicable to a national securities exchange, [^4] particularly Section 6(b)(5) of the Act which, among other things, requires that the rules of a national securities exchange be designed to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in regulating securities transactions, to remove impediments to and to perfect the mechanism of a free and open market and a national market system and, in general, to protect investors and the public interest. [^5] The Commission believes that the proposed rule change should help eliminate the distortive practice of trade shredding, and, therefore, promote just and equitable principles of trade.
[^4] In approving this proposed rule change, the Commission has considered the proposed rule's impact on efficiency, competition, and capital formation. *See* 15 U.S.C. 78c(f).
[^5] 15 U.S.C. 78f(b)(5).
**IV. Conclusion**
*It is therefore ordered* , pursuant to Section 19(b)(2) of the Act, [^6] that the proposed rule change (File No. SR-CHX-2006-03), be and hereby is, approved.
[^6] 15 U.S.C. 78s(b)(2).
