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 March 17, 2017, ISE Mercury, LLC (“ISE Mercury” or “Exchange”) filed with the Securities and Exchange Commission (“SEC” or “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 proposes to amend its Constitution, Limited Liability Company Agreement, Rule Book and Fee Schedule to rename itself Nasdaq MRX, LLC. In addition this rule change proposes to amend references to the names of certain affiliated markets within the ISE Mercury Rulebook.

The text of the proposed rule change is available on the Exchange's Web site at 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 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 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 purpose of the proposed rule change is to rename the Exchange to reflect its new placement within the Nasdaq, Inc. corporate structure in connection with the March 9, 2016 acquisition by Nasdaq of the capital stock of U.S. Exchange Holdings, and the thereby indirectly acquiring all of the interests of the International Securities Exchange, LLC, ISE Gemini, LLC, and ISE Mercury, LLC.

Specifically, all references in the Exchange's Constitution, Limited Liability Company Agreement, Rule Book and Fee Schedule to “ISE Mercury, LLC” or references to “Mercury” shall be amended to “Nasdaq MRX, LLC” or “Nasdaq MRX.” Moreover, consistent with changes already filed for ISE Gemini, LLC, the rule change proposes to amend references to “ISE Gemini” to “Nasdaq GEMX,” and references to the “International Securities Exchange” and “ISE” to “Nasdaq ISE.” The Exchange also proposes minor grammatical changes which are necessary as a result of the name change, i.e., amending “a” to “an.” The Exchange proposes to amend its name for ISE Mercury on April 3, 2017.

2. Statutory Basis

The Exchange believes that its proposal is consistent with Section 6(b) of the Act, in general, and furthers the objectives of Section 6(b)(5) of the Act, in particular, 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 by renaming the Exchange and updating the names of certain affiliated markets to reflect its current ownership.

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

The Exchange does not believe that the proposed rule change will impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Act. The Exchange does not believe that the proposed rule change will impact the intense competition that exists in the options market. The name change will reflect the current ownership structure and unify the options markets operated by Nasdaq, Inc.

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

No written comments were either solicited or received.

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, 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 pursuant to Rule 19b-4(f)(6) under the Act normally does not become operative for 30 days after the date of its 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 asked the Commission to waive the 30-day operative delay so that the Exchange may amend its name as of April 3, 2017. The Exchange stated that it intends to announce the name change for ISE Mercury and certain of its affiliated markets on the same date to reflect the unified ownership of these markets by Nasdaq, Inc. The Exchange believes that changing the names of all three affiliated markets at the same time is consistent with the protection of investors and the public interest because it will avoid any confusion that may arise with respect to the ownership by Nasdaq of the three markets, and will relieve various administrative burdens associated with the name changes. The Commission believes the waiver of the operative delay is consistent with the protection of investors and the public interest. Accordingly, the Commission hereby waives the operative delay and designates the proposed rule change operative upon filing.

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.
