[[Page 23499]]

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 amend Supplementary 
Material to Rule 706, which contains the Exchange's sponsored access 
rules, to harmonize these rules with those of the Nasdaq Exchanges.\3\ 
On March 9, 2016, the Exchange and its affiliates, International 
Securities Exchange, LLC (now, Nasdaq ISE, LLC) (``ISE'') and ISE 
Gemini, LLC (now, Nasdaq GEMX, LLC) (``GEMX'' and together with ISE and 
MRX, ``ISE Exchanges''), were acquired by Nasdaq, Inc. 
(``Acquisition'').\4\ In the context of the Acquisition, the ISE 
Exchanges have been working to align certain of its rules and processes 
with those of the Nasdaq Exchanges in order to provide consistent 
standards across the six exchanges owned and operated by Nasdaq, Inc. 
(collectively, ``Affiliated Exchanges''). As part of this effort, the 
proposal set forth below harmonizes the Exchange's sponsored access 
rules with the Nasdaq Sponsored Access Rules in order to provide 
uniform standards and requirements for users of the Affiliated 
Exchanges.\5\
---------------------------------------------------------------------------

    \3\ See NQX Rule 4615, BX Rule 4615 and PHLX Rule 1094 
(collectively, ``Nasdaq Sponsored Access Rules'').
    \4\ See Securities Exchange Act Release No. 78119 (June 21, 
2016), 81 FR 41611 (June 27, 2016) (SR-ISE-2016-11; SR-ISEGemini-
2016-05; SR-ISEMercury-2016-10).
    \5\ ISE and GEMX will each file similar rule change proposals 
with the Commission to harmonize their sponsored access rules with 
the Nasdaq Sponsored Access Rules.
---------------------------------------------------------------------------

    In particular, the Exchange proposes to (1) define the term 
``Sponsored Access'' and ``Customer Agreement;'' (2) specify the 
requirement to comply with Rule 15c3-5 under the Act (``Market Access 
Rule''); (3) remove the requirements that each Sponsored Customer and 
each Sponsoring Member enter into certain agreements with the Exchange; 
and (4) make a number of related, non-substantive changes. Each change 
is discussed in detail as follows.
Defining Sponsored Access
    A Sponsored Customer is a non-member of the Exchange, such as an 
institutional investor, that gains access to the Exchange \6\ and 
trades under a Sponsoring Member's execution and clearing identity 
pursuant to a sponsorship arrangement between such non-member and 
Sponsoring Member, as set forth in Supplementary Material to Rule 706. 
The Exchange is proposing to define the term ``Sponsored Access'' to 
clarify the type of market access arrangement that is subject to this 
rule. Accordingly, the Exchange proposes to amend Supplementary 
Material .01(a) to Rule 706 to add the following definition: 
``Sponsored Access shall mean an arrangement whereby a Member permits 
its customers to enter orders into the System that bypass the Member's 
trading system and are routed directly to the Exchange, including 
routing through a service bureau or other third party technology 
provider.'' This definition mirrors the language set forth in the 
Nasdaq Sponsored Access Rules,\7\ and is derived from the Commission's 
description of Sponsored Access used in the release approving the 
Market Access Rule.\8\ The Exchange believes that defining Sponsored 
Access in Supplementary Material .01(a) to Rule 706 will provide market 
participants with greater clarity regarding Sponsored Access and their 
obligations with respect to this type of access arrangement.
---------------------------------------------------------------------------

    \6\ For example, a broker-dealer may allow its customer--whether 
an institution such as a hedge fund, mutual fund, bank or insurance 
company, an individual, or another broker-dealer--to use the broker-
dealer's MPID, account or other mechanism or mnemonic used to 
identify a market participant for the purposes of electronically 
accessing the Exchange.
    \7\ See NQX Rule 4615(a), BX Rule 4615(a) and PHLX Rule 1094(a).
    \8\ The Market Access Rule, among other things, requires broker-
dealers providing others with access to an exchange or alternative 
trading system to establish, document, and maintain a system of risk 
management controls and supervisory procedures reasonably designed 
to manage the financial, regulatory, and other risks of providing 
such access. See Securities Exchange Act Release No. 63241 (November 
3, 2010), 75 FR 69792 (November 15, 2010).
---------------------------------------------------------------------------

Defining Customer Agreement
    The Exchange proposes to amend Supplementary Material .01(b)(1) to 
Rule 706 to define the agreement that Sponsored Customers must enter 
into and maintain with one or more Sponsoring Members to establish 
proper relationship(s) and account(s) through which the Sponsored 
Customer may trade on the Exchange, as a ``Customer Agreement.'' \9\
---------------------------------------------------------------------------

    \9\ The Nasdaq Sponsored Access Rules also similarly define 
``Customer Agreement.'' See NQX Rule 4615(b)(i), BX Rule 4615(b)(i) 
and PHLX Rule 1094(b)(i).
---------------------------------------------------------------------------

Market Access Rule
    Pursuant to Supplementary Material .01(b)(2) to Rule 706, the 
Sponsoring Member is responsible for the activities of the Sponsored 
Customer. Sponsored Customers are required to have procedures in place 
to comply with the Exchange's rules, and the Sponsoring Member takes 
responsibility for the Sponsored Customer's activity on the Exchange. 
Members may have multiple Sponsored Access relationships in place at a 
given time. The Exchange's examination program assesses compliance with 
the sponsored access rules set forth in Supplementary Material to Rule 
706, among other rules.\10\ The Exchange now proposes to specifically 
enumerate in Supplementary Material .01(b)(2) to Rule 706 the member's 
obligation to comply with the Market Access Rule, with which Members 
are currently required to comply in connection with market access.\11\ 
The Exchange believes that specifying the obligation to comply with the 
Market Access Rule within the rule itself will reinforce that 
Supplementary Material to Rule 706 presupposes member compliance with 
the Market Access Rule.
---------------------------------------------------------------------------

    \10\ The Exchange has a Regulatory Services Agreement (``RSA'') 
with the Financial Industry Regulatory Authority (``FINRA'') to 
conduct regulatory examinations, among other obligations.
    \11\ See NQX Rule 4615(b)(ii)(A), BX Rule 4615(b)(ii)(A) and 
PHLX Rule 1094(b)(ii)(A) for consistent provisions.
---------------------------------------------------------------------------

Elimination of Certain Contract Requirements
    The Exchange currently requires a Sponsored Customer Agreement 
between the Sponsored Customer and the Exchange,\12\ and a Sponsored 
Customer Addendum to the member access agreement (hereinafter, 
``Addendum'') that is provided to the Exchange by the Sponsoring 
Member.\13\ At this time, the Exchange proposes to remove the existing 
requirements to submit the Sponsored Customer Agreement and Addendum to 
the Exchange in order to align its sponsored access rules with the 
Nasdaq Sponsored Access Rules. The Exchange will continue to require a 
Customer Agreement between the Sponsored Customer and Sponsoring Member

[[Page 23500]]

pursuant to Supplementary Material .01(b)(2) to Rule 706.\14\
---------------------------------------------------------------------------

    \12\ See Supplementary Material .01(a) to Rule 706.
    \13\ See Supplementary Material .01(b)(2)(i) and (b)(3) to Rule 
706.
    \14\ The Nasdaq Sponsored Access Rules likewise only require a 
Customer Agreement between the sponsored participant and sponsoring 
member. See NQX Rule 4615(b)(i), BX Rule 4615(b)(i) and PHLX Rule 
1094(b)(i).
---------------------------------------------------------------------------

    Today, only members may request connectivity to the Exchange by 
contacting Nasdaq Subscriber Services. A member may obtain separate 
ports for the purpose of providing Sponsored Access. If separate ports 
are requested by a member for the purpose of providing Sponsored 
Access, the member must request those ports from the Exchange and is 
responsible for the Sponsored Customer's activity on the Exchange.\15\ 
In all circumstances, the Exchange only permits members to request 
connectivity to the market and the member is responsible for all 
customer orders submitted through the member's port. In addition, such 
connection by the member requires approval by the Exchange for the 
purpose of testing as well as other relevant information sharing with 
the Exchange by the member to obtain a port. The Exchange is therefore 
aware of the member responsible for each of its ports. The Exchange may 
also request further information about a member's particular customer 
relationship, including the list of all Authorized Traders who may have 
access to the Exchange on behalf of the Sponsored Customer, as it deems 
necessary.\16\
---------------------------------------------------------------------------

    \15\ In such cases, the Nasdaq Exchanges also require members to 
disclose the sponsored access arrangement as a condition to 
approving the member's port request. MRX will similarly require 
members requesting connectivity to MRX for the purpose of providing 
Sponsored Access to disclose sponsored access arrangements as a 
condition to approval.
    \16\ See Rule 1601.
---------------------------------------------------------------------------

    The Exchange believes that completing and submitting the Sponsored 
Customer Agreement and Addendum is unnecessarily burdensome in light of 
the current structure in place at the Exchange. The Sponsored Customer 
Agreement requirement was intended to ensure that the Sponsored 
Customer was informed of its obligation to comply with the Exchange's 
Certificate of Formation, By-Laws, Rules and procedures, including the 
requirements in Supplementary Material .01(b)(2)(iii)-(ix).\17\ The 
agreement also provided the Exchange with contractual privity, which 
would no longer exist with the removal of the Sponsored Customer 
Agreement. The Exchange does not believe the loss of privity with the 
Sponsored Customer creates a concern as the Exchange has the ability to 
remove access to the port at any time if it determines that the 
activity of the Sponsored Customer warrants such removal. In addition, 
as discussed below, the Sponsored Customer will be informed of its 
obligations through the Customer Agreement that it executed with the 
Sponsoring Member. As noted above, the Exchange only permits its 
members to request connectivity to the Exchange's trading system, and 
members remain responsible for all trades submitted through such ports. 
Pursuant to Supplementary Material .01(b)(2)(vii) to Rule 706, the 
trading activity of a Sponsored Customer must be monitored by the 
Sponsoring Member for compliance with the terms of the Customer 
Agreement with the Sponsored Customer. Finally, Sponsoring Members 
continue to be obligated to comply with Supplementary Material .01(b) 
to Rule 706 and the Market Access Rule. As such, the Sponsoring Member 
is responsible for any and all actions taken by its Sponsored Customer 
and any person acting on behalf of or in the name of such Sponsored 
Customer.
---------------------------------------------------------------------------

    \17\ These requirements include, among others, the Sponsored 
Customer's obligation to maintain, keep current and provide to the 
Sponsoring Member a list of Authorized Traders who may obtain access 
to the Exchange on behalf of the Sponsored Customer. In addition, 
the Sponsored Customer must take reasonable security precautions to 
prevent unauthorized use or access to the Exchange, and is 
responsible for having adequate procedures and controls in place to 
comply with MRX's rules.
---------------------------------------------------------------------------

    The Addendum requirement was intended to notify the Exchange of the 
relationship between the Sponsoring Member and the Sponsored Customer, 
and to provide the Sponsoring Member's express acknowledgment of the 
Sponsoring Member's responsibility for the orders, executions and 
actions of its Sponsored Customer. However, as noted above, the 
Exchange may request additional information about a particular customer 
relationship as it deems necessary.\18\ The Exchange will also require 
that its members disclose the Sponsored Customer relationship as a 
condition for approving any ports requested for the purpose of 
providing Sponsored Access.\19\ Accordingly, the Exchange will continue 
to be notified of Sponsored Customer arrangements even with the removal 
of the Addendum. Furthermore, as discussed above, Sponsoring Members 
continue to be obligated to comply with Supplementary Material .01(b) 
to Rule 706 and the Market Access Rule, and are therefore responsible 
for any and all actions taken by its Sponsored Customer and any person 
acting on behalf of or in the name of such Sponsored Customer. The 
Exchange, through its RSA with FINRA, reviews member compliance with 
Supplementary Material to Rule 706, including compliance with the 
Market Access Rule.
---------------------------------------------------------------------------

    \18\ See Rule 1601.
    \19\ See note 15 above.
---------------------------------------------------------------------------

    Supplementary Material .01(b)(1) to Rule 706 requires that the 
Sponsored Customer and the Sponsoring Member maintain a Customer 
Agreement with the sponsorship provisions set forth in paragraph (2) to 
ensure compliance with Exchange's rules and obligations related to 
security, among other things. Additionally, Supplementary Material 
.01(b)(2)(iv) and (v) require that the Customer Agreement include the 
Sponsored Customer's obligation to maintain, keep current and provide 
to the Sponsoring Member a list of Authorized Traders who have been 
granted access to the Exchange on behalf of the Sponsored Customer, and 
provide such Authorized Traders with appropriate training prior to any 
use or access to the Exchange. In addition, pursuant to the Customer 
Agreement provisions required by Rule 706, Supplementary Material 
.01(b)(vii), the Sponsored Customer is obligated to take reasonable 
security precautions to prevent unauthorized use or access to the 
Exchange, including unauthorized entry of information into the 
Exchange's System, or the information and data made available therein. 
Finally, the Customer Agreement must provide that the Sponsored 
Customer is responsible for any and all orders, trades and other 
messages and instructions entered, transmitted or received under 
identifiers, passwords and security codes of Authorized Traders, and 
for the trading and other consequences thereof, including granting 
unauthorized access to the Exchange.\20\ The contents and the 
requirement for a Customer Agreement are unchanged.
---------------------------------------------------------------------------

    \20\ See Rule 706, Supplementary Material .01(b)(vii).
---------------------------------------------------------------------------

Clean-Up Changes
    The Exchange proposes to correct two typographical errors in 
subsections (vii) and (ix) of Supplementary Material .01(b)(2) to Rule 
706. First in subsection (vii), the Exchange proposes to correct a typo 
by replacing ``of'' with ``or'' in the first sentence. The proposed 
sentence would therefore state ``Sponsored Customer shall take 
reasonable security precautions to prevent unauthorized use or access 
to the Exchange . . .''
    Second, subsection (ix) would be amended to correct a typo in the 
last portion of the first sentence. In particular, the phrase ``. . . 
Sponsored Customers access to and use of the Exchange'' should be ``. . 
. Sponsored

[[Page 23501]]

Customer's access to and use of the Exchange.'' Both of these proposed 
changes are non-substantive clean-ups, and are intended to ensure that 
the rule text is as accurate and clear as possible.
2. Statutory Basis
    The Exchange believes that its proposal is consistent with Section 
6(b) of the Act,\21\ in general, and furthers the objectives of Section 
6(b)(5) of the Act,\22\ 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. Overall, the proposed rule change is intended to align the 
Exchange's sponsored access rules in Supplementary Material to Rule 706 
with the Nasdaq Sponsored Access Rules, and is part of the Exchange's 
continued effort to promote efficiency and conformity of its processes 
with those of the Nasdaq Exchanges. Consistent rules and processes 
across the Affiliated Exchanges would in turn simplify the regulatory 
requirements for members of the Exchange that are also participants on 
the Nasdaq Exchanges. The Exchange believes that its proposal would 
provide greater harmonization among similar rules and procedures of the 
Affiliated Exchanges, resulting in greater uniformity and more 
efficient regulatory compliance. As such, the proposed rule change 
would foster cooperation and coordination with persons engaged in 
facilitating transactions in securities and would remove impediments to 
and perfect the mechanism of a free and open market and national market 
system.

    \21\ 15 U.S.C. 78f(b).
    \22\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

Defining Sponsored Access
    Adding a definition of Sponsored Access will assist market 
participants to understand the type of arrangements that are subject to 
Supplementary Material to Rule 706, and such clarity will serve to 
promote just and equitable principles of trade. The Exchange believes 
that adding the Sponsored Access definition will provide its members 
with additional guidance with respect to this Rule.
Defining Customer Agreement
    Defining the agreement that Sponsored Customers must enter into and 
maintain with one or more Sponsoring Members to establish proper 
relationship(s) and account(s) through which the Sponsored Customer may 
trade on the Exchange, as a ``Customer Agreement'' will also serve to 
provide members with clarity on the agreement that the Exchange will 
continue to require and the obligations that are contained within the 
Customer Agreement. This amendment is non-substantive.
Market Access Rule
    As discussed above, Exchange members will continue to be required 
to comply with Supplementary Material to Rule 706 and the Market Access 
Rule. The Exchange believes that specifically enumerating the member's 
responsibility to comply with the Market Access Rule within the Rule 
itself will provide members with additional guidance concerning the 
application of the Rule. This change is non-substantive as members are 
currently responsible for complying with the Market Access Rule.
Elimination of Certain Contract Requirements
    Removing the requirements to submit and complete a Sponsored 
Customer Agreement and Addendum will remove impediments to and perfect 
the mechanism of a free and open market by aligning the Exchange's 
sponsored access rules with the Nasdaq Sponsored Access Rules, which 
currently do not require additional agreements for their sponsored 
participants other than a Customer Agreement.\23\ The Exchange believes 
that its proposal would create equivalent sponsored access standards 
and requirements among the Affiliated Exchanges and also provide 
clarity to its members, which is beneficial to both investors and the 
public interest. While elimination of the Sponsored Customer Agreement 
requirement will also eliminate the Exchange's contractual privity with 
the Sponsored Customer, the Exchange notes that any potential concerns 
to the loss of privity are mitigated by the Exchange's ability to 
restrict the Sponsored Customer's access to a port at any time it is 
warranted by the Sponsored Customer's trading activity. As discussed 
above, connectivity to the Exchange must be requested by a member of 
the Exchange. Such connection requires approval by the Exchange, 
testing and other security features as well as information sharing with 
the Exchange by the member. In addition, Supplementary Material 
.01(b)(2) to Rule 706 delineates the terms of the required contractual 
relationship between the Sponsoring Member and the Sponsored Customer 
in the Customer Agreement, which remains in effect. The Exchange also 
believes that the Addendum is unnecessary in light of the fact that 
Sponsoring Members must request connectivity to the Exchange as well as 
enter into a Customer Agreement with the Sponsored Customer. 
Furthermore, as discussed above, the Exchange will require members to 
disclose the Sponsored Customer relationship as a condition to 
approving the member's port request to provide Sponsored Access. 
Finally, as is the case with other Exchange rules, the Exchange 
examines for compliance with Supplementary Material to Rule 706 and may 
request information about any customer relationship which concerns the 
Exchange pursuant to Rule 1601.
---------------------------------------------------------------------------

    \23\ See NQX Rule 4615, BX Rule 4615 and PHLX Rule 1094.
---------------------------------------------------------------------------

Clean-Up Changes
    The Exchange believes that the proposed changes to correct the two 
typos in subsections (vii) and (ix) of Supplementary Material .01(b)(2) 
to Rule 706 will add further clarification to the Exchange's Rulebook 
and alleviate potential confusion as to the applicability of the 
Exchange's rules, which will protect investors and the public interest.

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 because all members would be 
subject to the same sponsored access requirements, as discussed above. 
The proposed rule change is designed to provide greater harmonization 
among the sponsored access rules across the Affiliated Exchanges, 
resulting in more efficient regulatory compliance for common members, 
and is not intended to have any competitive effect.

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 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 from the date on which it was filed, or 
such shorter time as the Commission may designate, it has

[[Page 23502]]

become effective pursuant to Section 19(b)(3)(A)(iii) of the Act \24\ 
and subparagraph (f)(6) of Rule 19b-4 thereunder.\25\
---------------------------------------------------------------------------

    \24\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \25\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6) 
requires a self-regulatory organization to give the Commission 
written notice of its intent to file the proposed rule change at 
least five business days prior to the date of filing of the proposed 
rule change, or such shorter time as designated by the Commission. 
The Exchange has satisfied this requirement.
---------------------------------------------------------------------------

    A proposed rule change filed pursuant to Rule 19b-4(f)(6) under the 
Act \26\ normally does not become operative for 30 days after the date 
of its filing. However, Rule 19b-4(f)(6)(iii) \27\ 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 
represents that waiver of the operative delay would allow the Exchange 
to harmonize its sponsored access rule to the rules of the Nasdaq 
Exchanges.\28\ The Commission believes that waiving the 30-day 
operative delay is consistent with the protection of investors and the 
public interest because the proposed rule change would simplify the 
regulatory requirements of members of the Exchange that are also 
participants on the Nasdaq Exchanges. Further, the Commission does not 
believe that the proposed rule change raises any new or novel issues. 
Accordingly, the Commission hereby waives the operative delay and 
designates the proposal operative upon filing.\29\
---------------------------------------------------------------------------

    \26\ 17 CFR 240.19b-4(f)(6).
    \27\ 17 CFR 240.19b-4(f)(6)(iii).
    \28\ See supra note 3.
    \29\ For purposes only of waiving the 30-day operative delay, 
the Commission has also considered the proposed rule's impact on 
efficiency, competition, and capital formation. See 15 U.S.C. 
78c(f).
---------------------------------------------------------------------------

    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: (i) 
Necessary or appropriate in the public interest; (ii) for the 
protection of investors; or (iii) 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.

IV. Solicitation of Comments

arguments concerning the foregoing, including whether the proposed rule 
change is consistent with the Act. Comments may be submitted by any of 
the following methods:
