Self-Regulatory Organizations; ISE Mercury, LLC; Notice of Filing of Proposed Rule Change Relating to Preferenced Volume

Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”), and Rule 19b-4 thereunder, notice is hereby given that on April 13, 2016, ISE Mercury, LLC (the “Exchange” or “ISE Mercury”) 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 self-regulatory organization. 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 the Substance of the Proposed Rule Change

The purpose of this proposed rule change is to amend the Exchange's Schedule of Fees to explain that while 100% of eligible traded volume preferenced to a Market Maker counts towards that member's volume tiers, Market Makers not preferenced on an order will receive credit for the volume those non-preferenced members execute. The text of the proposed rule change is available on the Exchange's Web site ( http://www.ise.com ), at the principal office of the Exchange, 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 self-regulatory organization 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 self-regulatory organization 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

On March 10, 2016, ISE Mercury introduced fee and rebate tiers for Market Maker and Priority Customer orders based on the average daily volume (“ADV”) that a member executes in Priority Customer orders. The Exchange assesses fees and rebates for Market Maker and Priority Customer orders based on five tiers of Total Affiliated Priority Customer ADV, as described in Table 4 of the Fee Schedule: 0—19,999 contracts (“Tier 1”), 20,000—39,999 contracts (“Tier 2”), 40,000—59,999 contracts (“Tier 3”), 60,000—79,999 contracts (“Tier 4”), and 80,000 or more contracts (“Tier 5”). As is the case on ISE Mercury's affiliated exchanges—the International Securities Exchange, LLC (“ISE”) and ISE Gemini, LLC (“ISE Gemini”)—the Exchange's ADV calculation includes volume executed by affiliated members. In particular, the Exchange aggregates all eligible volume from affiliated members in determining applicable tiers, provided that there is at least 75% common ownership between the members as reflected on the member's Form BD, Schedule A. While this method of aggregating volume is beneficial to large firms with multiple affiliated members, the Exchange believed that it was also important to give smaller firms the ability to compete for more favorable fees and rebates.

On March 10, 2016, the Exchange adopted ADV tiers that are based on preferenced volume —i.e., volume directed to a specific Market Maker as provided in Supplementary Material .03 to Rule 713. In particular, the Exchange gives Market Makers volume credit for 100% of eligible traded volume preferenced to that member, regardless of the actual allocation that the Market Maker receives. For example, assume Market Maker ABC is quoting at the national best bid or offer (“NBBO”) and receives a Preferenced Order for 10 contracts from an unaffiliated firm for the account of a Priority Customer. If there are other Market Makers quoting at the NBBO, Market Maker ABC may receive an allocation of 4 contracts—i.e., 40% of the order. Rather than counting only the 4 contracts executed towards the Market Maker's volume total, the Exchange gives that Market Maker credit for the full 10 contracts preferenced to it. This is the same credit the member would receive if the 10 contracts were sent to the exchange by an affiliated member. The purpose of the current rule filing is to clarify that even though Market Maker ABC receives full credit for all 10 contracts when executing 4 contracts, the non-preferenced Market Makers that execute the remaining 6 contracts will still receive credit for those 6 contracts as they normally would.

2. Statutory Basis

The Exchange believes that the proposed rule change 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. In particular, the proposal is consistent with Section 6(b)(5) of the Act, because it is designed to promote just and equitable principles of trade, remove impediments to and perfect the mechanisms of a free and open market and a national market system and, in general, to protect investors and the public interest. The Exchange believes that the proposed clarification is reasonable and equitable because it will eliminate member confusion regarding how volume is counted among Market Makers when contracts are preferenced to a Market Maker and executed by preferenced and non-preferenced Market Makers.

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

In accordance with Section 6(b)(8) of the Act, the Exchange does not believe that the proposed rule change will impose any burden on intermarket or intramarket competition that is not necessary or appropriate in furtherance of the purposes of the Act. To the contrary, the Exchange believes that the proposed rule change merely clarifies an existing rule already in effect.

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

The Exchange has not solicited, and does not intend to solicit, comments on this proposed rule change. The Exchange has not received any written comments from members or other interested parties.

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

Because the 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 from the date on which it was filed, or such shorter time as the Commission may designate if consistent with the protection of investors and the public interest, the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6) thereunder.

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. If the Commission takes such action, the Commission shall institute proceedings to determine whether the proposed rule should be approved or disapproved.
