###### Securities and Exchange Commission

          - [Release No. 34-66325; File No. SR-BYX-2012-004]

Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) [1]            and Rule 19b-4 thereunder,[2]            notice is hereby given that on February 1, 2012, BATS Y-Exchange, Inc. (the “Exchange” or “BYX”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I and II below, which Items have been prepared by the Exchange. 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 is filing with the Commission a proposed rule change to amend BYX Rule 11.13(a)(3)(G) to add reference to a variation of the TRIM routing strategy.

The text of the proposed rule change is available at the Exchange's Web site at *http://www.batstrading.com,* at the principal office of the Exchange, and at the Commission's Public Reference Room.      ( print page 7641)    

## 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 these 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 parts 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 purpose of the proposed rule change is to add reference in Rule 11.13(a)(3)(G) to a variation of the TRIM routing strategy, to be identified as TRIM2. The TRIM routing strategy checks the System for available shares and then routes to destinations on the System routing table. The TRIM routing strategy is focused on seeking execution of orders while minimizing execution costs by routing to certain low cost execution venues on the Exchange's System routing table. No changes to the functionality of the TRIM routing strategy are proposed by this filing. The Exchange, however, is proposing to offer an additional variation for TRIM routing, TRIM2, which will offer a different routing table to be used pursuant to the TRIM routing strategy. Specifically, TRIM2 will route to fewer venues than the full list of TRIM routing venues.

#### 2. Statutory Basis

The Exchange believes that its proposal is consistent with the requirements of the Act and the rules and regulations thereunder that are applicable to a national securities exchange, and, in particular, with the requirements of Section 6(b) of the Act.[3]            In particular, the proposed change is consistent with Section 6(b)(5) of the Act,[4]            because it would promote just and equitable principles of trade, remove impediments to, and perfect the mechanism of, a free and open market and a national market system, and, in general, protect investors and the public interest. The proposed change to introduce an additional variation of an existing routing strategy will provide market participants with greater flexibility in routing orders consistent with Regulation NMS without developing complicated order routing strategies on their own.

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

The Exchange does not believe that the proposed rule change imposes any burden on competition.

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

The Exchange has neither solicited nor received written comments on the proposed rule change.

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

Because the foregoing proposed 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 for 30 days after the date of the filing, or such shorter time as the Commission may designate, it has become effective pursuant to Section 19(b)(3)(A) of the Act [5]            and Rule 19b-4(f)(6) [6]            thereunder.

A proposed rule change filed under Rule 19b-4(f)(6) normally may not become operative prior to 30 days after the date of filing.[7]            However, Rule 19b-4(f)(6)(iii) [8]            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 asked the Commission to waive the 30-day operative delay so that the proposal may become operative immediately upon filing. The Exchange believes that waiving the 30-day operative delay will allow market participants and their customers to benefit from the greater flexibility in routing their orders and minimize their trading costs without further delay. The Exchange notes that the introduction of the additional optional variation of the TRIM routing strategy will not require any systems changes by Exchange Users that would necessitate a delay, as selection of the TRIM2 variation is entirely optional and Exchange Users will not be affected by the change unless they select to use the newly offered variation. The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest. Therefore, the Commission designates the proposal as operative upon filing.[9] 

At any time within 60 days of the filing of the proposed rule change, the Commission summarily may temporarily suspend 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.

## IV. Solicitation of Comments
