Self-Regulatory Organizations; Nasdaq ISE, LLC; Notice of Filing 
and Immediate Effectiveness of Proposed Rule Change To Amend Options 3, 
Section 13 Related to PIM

September 20, 2023.
    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 September 8, 2023, Nasdaq ISE, LLC (``ISE'' or ``Exchange'') filed 
with the Securities and Exchange Commission (the ``Commission'') the 
proposed rule change as described in Items I, II, and III, 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 Options 3, Section 7, Types of 
Orders and Order and Quote Protocols; Options 3, Section 11, Auction 
Mechanisms; and Options 3, Section 13, Price Improvement Mechanism for 
Crossing Transactions.
    The text of the proposed rule change is available on the Exchange's 
website at https://listingcenter.nasdaq.com/rulebook/ise/rules, 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 Exchange proposes to amend Options 3, Section 7, Types of 
Orders and Order and Quote Protocols; Options 3, Section 11, Auction 
Mechanisms; and Options 3, Section 13, Price Improvement Mechanism for 
Crossing Transactions. Each change is described below.
Options 3, Section 7
Opening Only
    The Exchange proposes to amend Options 3, Section 7(u), Opening 
Sweep \3\ and Supplementary Material .02(e) to Options 3, Section 7 
related to Opening Only \4\ or ``OPG'' orders. The proposed rule text 
was adopted as part of a planned System migration.\5\

[[Page 66107]]

Options 3, Section 7(t) currently provides that an Opening Sweep would 
not be subject to any protections listed in Options 3, Section 15, 
except Automated Quotation Adjustments in Options 3, Section 15. 
Supplementary Material .02(e) to Options 3, Section 7 currently 
provides that an OPG Order would not be subject to any protections 
listed in Options 3, Section 15, except Size Limitation. At this time, 
the Exchange proposes to amend the rule text to specify that an Opening 
Sweep and an OPG Order would be subject to the Market Wide Risk 
Protection in Options 3, Section 15.
---------------------------------------------------------------------------

    \3\ An Opening Sweep is a one-sided order entered by a Market 
Maker through SQF for execution against eligible interest in the 
System during the Opening Process. This order type is not subject to 
any protections listed in Options 3, Section 15, except for 
Automated Quotation Adjustments. The Opening Sweep will only 
participate in the Opening Process pursuant to Options 3, Section 
8(b)(1) and will be cancelled upon the open if not executed. See 
Options 3, Section 7(u).
    \4\ An Opening Only (``OPG'') order is entered with a TIF of 
``OPG.'' This order can only be executed in the Opening Process 
pursuant to Options 3, Section 8. This order type is not subject to 
any protections listed in Options 3, Section 15, except Size 
Limitation. Any portion of the order that is not executed during the 
Opening Process is cancelled. OPG orders may not route. See 
Supplementary Material .02(e) to Options 3, Section 7.
    \5\ See Securities Exchange Act Release No. 96821 (February 6, 
2023), 88 FR 8950 (February 10, 2023) (SR-ISE-2023-06) (Notice of 
Filing and Immediate Effectiveness of Proposed Rule Change To Amend 
Its Rules in Connection With a Technology Migration to Enhanced 
Nasdaq, Inc. (``Nasdaq'') Functionality) (``SR-ISE-2023-06'').
---------------------------------------------------------------------------

    The Market Wide Risk Protection in Options 3, Section 15(a)(1)(C) 
automatically removes Member orders when certain firm-set thresholds 
are met. Specifically, the Market Wide Risk Protection requires all 
Members to provide parameters for the order entry and execution rate 
protections. The Market Wide Risk Protection would apply to an Opening 
Sweep and an OPG Order because it captures the order entry and 
execution rate for both Opening Sweeps and OPG Orders that are entered 
in the Opening Process as described in Options 3, Section 8. The 
Exchange believes the availability of the Market Wide Risk Protection 
during the Opening Process would assist Members in managing their pre-
open risk by allowing Members to adhere to their firm thresholds. The 
Exchange notes that other risk protections within Options 3, Section 15 
do not apply to wither an Opening Sweep or an Opening Only Order 
because the risk protection either relies on the BBO, which available 
after the Opening Process, or the risk protection is optional. Finally, 
the Exchange also proposes a technical amendment to capitalize the word 
``orders'' in Supplementary Material .02(e) to Options 3, Section 7.
Options 3, Sections 11 and 13
    The Exchange proposes to amend Options 3, Section 11(b)(4)(A) 
related to the Facilitation Mechanism. Currently, the last sentence in 
Options 3, Section 11(b)(4)(A) provides that a facilitation order will 
be cancelled at the end of an exposure period if an execution would 
take place at a price that is inferior to the best bid (offer) on ISE. 
The Exchange proposes to amend this sentence to state, the ``Exchange 
best bid (offer)'' and remove the phrase ``on Nasdaq ISE.'' 
Additionally, the Exchange proposes to add the following rule text to 
the end of the sentence, ``or if there is a Priority Customer order on 
the same side Exchange best bid (offer) at the same price as the 
facilitation price unless the Facilitation Order can execute at a price 
that is better than the same side Priority Customer Order.'' Today, a 
facilitation order must execute at a price that is better than the same 
side BBO if there is a Priority Customer order on the same side. The 
proposed rule text is being amended to align to current System 
functionality which prevents a Facilitation Order from trading ahead of 
a Priority Customer Order. As such, a Priority Customer order on the 
same side of the offer must be considered when executing a Facilitation 
Order. The Exchange proposes to add similar language to the last 
sentence of Options 3, Section 11(d)(3)(A) related to the Solicited 
Order Mechanism. The Exchange notes that these amendments do not amend 
the current System functionality.
    The Exchange proposes to add a new Options 3, Section 11(b)(4)(iv) 
to describe the allocation percentage that an Electronic Access Member 
is able to obtain in the Facilitation Mechanism. Today, under the 
current System operation, the facilitating Electronic Access Member may 
not receive an allocation percentage, at the final price point, of more 
than 40% of the original size of the Facilitation Order with one or 
multiple competing quote(s), order(s), or Response(s), except for 
rounding,\6\ when competing quotes, orders, or Responses have contracts 
available for execution. Options 3, Section 11(b)(4)(ii) makes clear 
that the facilitating Electronic Access Member will be allocated up to 
forty percent (40%) (or such lower percentage requested by the Member) 
of the original size of the facilitation order, but only after better-
priced Responses, orders and quotes, as well as Priority Customer 
Orders and Priority Customer Responses at the facilitation price, are 
executed in full at such price point. The proposed rule text expressly 
notes that the allocation percentage will not be exceeded except for 
rounding purposes. This language represents current System 
functionality. The Exchange proposes to add similar language to Options 
3, Section 11(c)(7)(E) related to the Complex Facilitation Mechanism, 
Options 3, Section 13(d)(7) related to the Price Improvement Mechanism 
for Crossing Transactions, and Options 3, Section 13(e)(5)(vi) related 
to the Complex Price Improvement Mechanism to note the limitations with 
respect to allocations.
---------------------------------------------------------------------------

    \6\ ISE's System will round up to the nearest whole number 
during the allocation in the Facilitation Mechanism.
---------------------------------------------------------------------------

    The Exchange proposes to amend Supplementary Material .04 to 
Options 3, Section 11 to replace the word ``quotes'' with ``Responses'' 
in the Split Price description. Orders and responses in the market that 
receive the benefit of the facilitation price may receive executions at 
Split Prices. This change to the rule text is intended to utilize the 
defined term ``Response'' pursuant to Options 3, Section 11(b)(3) may 
be priced at the price of the order to be facilitated or at a better 
price and will only be considered up to the size of the order to be 
facilitated.
    The Exchange proposes to add a new Supplementary Material .09 to 
Options 3, Section 11 and a new Supplementary Material .09 to Options 
3, Section 11 to provide that, today, if an allocation would result in 
less than one contract, then one contract will be allocated. The 
Exchange does not allocate fractional contracts. This language 
represents the current System functionality. The Exchange proposes to 
add the same sentence within new Supplementary Material .10 to Options 
3, Section 13 regarding a PIM. Phlx has similar language.\7\
---------------------------------------------------------------------------

    \7\ See Phlx Options 3, Section 13(b)(1)(D).
---------------------------------------------------------------------------

    The Exchange proposes to amend Options 3, Section 13(b)(1) through 
(3) to harmonize the language within the PIM entry checks with language 
within Nasdaq GEMX, LLC's (``GEMX'') PIM, Nasdaq MRX, LLC's (``MRX'') 
PIM, Nasdaq Phlx LLC's (``Phlx'') PIXL and BX's PRISM, without changing 
the substantive operations of these price improvement auctions. The 
Exchange believes that by utilizing similar language, Members will be 
able to compare ISE's PIM entry checks with similar mechanisms on 
Nasdaq affiliated markets.
    ISE proposes to add ``a price that is'' to the end of Options 3, 
Section 13(b)(1) and add new subparagraphs (A) and (B) to distinguish 
opposite and same side checks. The opposite side check is currently 
spelled out in the current rule text, however the same side check does 
not specify the NBBO check. Today, if the Agency Order is for less than 
50 option contracts, and if the difference between the NBBO or the 
difference between the internal best bid and the internal best offer is 
$0.01, the Crossing Transaction must be entered at a price that is, on 
the same side of the Agency Order equal or better than the NBBO and 
better than any Limit Order or quote on ISE's order book. The Exchange 
believes that the addition of the NBBO

[[Page 66108]]

check will add clarity to the rule text because the NBBO check is 
always relevant in the same side check to avoid a trade-through. The 
Exchange also proposes to capitalize ``Limit Order,'' remove the word 
``Nasdaq'' before ``ISE'' and remove other extraneous words as the 
sentence has been rearranged.
    Next, the Exchange proposes to bifurcate the entry check for Agency 
Orders of 50 options contracts or more for the account of a Priority 
Customer from the entry checks for the account of a broker dealer or 
any other person or entity that is not a Priority Customer similar to 
other Nasdaq affiliated markets to provide consistent formatting. While 
the entry checks for new Options 3, Section 13(b)(2) and (b)(3) will 
not differ, the Exchange believes that retaining the same rule text 
format across its Nasdaq affiliated markets will allow for an easier 
comparison. To that end, the Exchange proposes to amend Options 3, 
Section 13(b)(2) to format it similar to Options 3, Section 13(b)(1). 
The Exchange proposes to add ``for the account of a Priority Customer'' 
to (b)(2) to distinguish it from (b)(3) which addresses the account of 
a broker dealer or any other person or entity that is not a Priority 
Customer. Options 3, Section 13(b)(2)(A) will also add rule text to 
address the opposite side of the market, which is not explicitly noted. 
Proposed Options 3, Section 13(b)(2)(A) will provide that if the Agency 
Order is for the account of a Priority Customer, and such order is for 
50 option contracts or more, or if the difference between the NBBO or 
the difference between the internal BBO is greater than $0.01, a 
Crossing Transaction must be entered only at a price that is equal to 
or better than the internal BBO and NBBO on the opposite side of the 
market from the Agency Order. Further, Options 3, Section 13(b)(2)(B) 
will explicitly note the entry check on the same side of the market and 
similar to Options 3, Section 13(b)(1) will include the NBBO check. 
Proposed Options 3, Section 13(b)(2)(B) will provide that if the Agency 
Order is for the account of a Priority Customer, and such order is for 
50 option contracts or more, or if the difference between the NBBO or 
the difference between the internal BBO is greater than $0.01, a 
Crossing Transaction must be entered only on the same side of the 
market as the Agency Order, at a price that is at least $0.01 better 
than any Limit Order or quote on the ISE order book and equal to or 
better than the NBBO.\8\ The Exchange believes that the addition of the 
NBBO check will add clarity to the rule text because the NBBO check is 
always relevant in the same side check to avoid a trade-through. The 
Exchange also proposes to capitalize ``Limit Order,'' remove the word 
``Nasdaq'' before ``ISE'' and remove other extraneous words as the 
sentence has been rearranged.
---------------------------------------------------------------------------

    \8\ For example, if the market is 0.98 bid and 0.99 offer, a 
Priority Customer PIM Order to buy for less than 50 contracts must 
be stopped at 0.98 cents in this scenario to be accepted into a PIM 
Auction, provided there is no resting order or quote on the Exchange 
order book at 0.98 in which case the PIM Order would be rejected.
---------------------------------------------------------------------------

    As noted herein, proposed Options 3, Section 13(b)(3) will mirror 
Options 3, Section 13(b)(2) except that it will refer to the account of 
a broker dealer or any other person or entity that is not a Priority 
Customer. The Exchange also proposes to renumber the remainder of the 
paragraphs within Options 3, Section 13(b).
    Finally, the Exchange proposes to add a new Options 3, Section 
13(e)(5)(vii), similar to rule text in Phlx at Options 3, Section 
13(b)(8) for Complex Orders. The current ISE Complex Price Improvement 
Mechanism rule text is silent as to same side execution price 
validations. The Exchange proposes to state,

    [i]f the Complex PIM execution price would be the same or better 
than a Complex Order on the Complex Order Book on the same side of 
the market as the Agency Complex Order, for options classes assigned 
to allocate in time priority or pro-rata pursuant to Options 3, 
Section 14(d)(2), the Agency Complex Order may be executed at a 
price that is equal to the resting Complex Order's limit price.

    Today, if the Complex PIM execution is the same or better than the 
Complex Order resting on the Complex Order Book on the same side of the 
market as the Agency Complex Order, for options assigned to allocate in 
time priority or pro-rata pursuant to Options 3, Section 14(d)(2), the 
Agency Complex Order may execute at a price that is equal to the 
resting Complex Order's limit price. This proposed rule text would make 
clear the manner in which the System validates prices for Complex PIMs 
on the same side of the market.
Implementation
    The Exchange proposes to amend the Opening Sweep and Opening Only 
rule text only, within Options 3, Section 7, with its planned migration 
to enhanced Nasdaq functionality. Similar to SR-ISE-2023-10,\9\ the 
Exchange intends to begin implementation of the amendments to the 
Opening Sweep and Opening Only rule text within Options 3, Section 7 
prior to December 20, 2024. The Exchange would commence its 
implementation with a limited symbol migration and continue to migrate 
symbols over several weeks. The Exchange will issue an Options Trader 
Alert to Members to provide notification of the symbols that will 
migrate and the relevant dates. The other rule amendments would be 
operative 30 days from the effective date.

and Immediate Effectiveness of Proposed Rule Change To Delay the 
Implementation of Certain Trading Functionality) (``SR-ISE-2023-
10'').
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes that its proposal is consistent with Section 
6(b) of the Act,\10\ in general, and furthers the objectives of Section 
6(b)(5) of the Act,\11\ in particular, in that it is designed to 
promote just and equitable principles of trade and to protect investors 
and the public interest.

    \11\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

Options 3, Section 7
Opening Only
    The Exchange's proposal to amend Options 3, Section 7(u), Opening 
Sweeps and Supplementary Material .02(e) to Options 3, Section 7 
related to OPG Orders is consistent with the Act and the protection of 
investors and the general public because the Market Wide Risk 
Protection would capture the order entry and execution rate for those 
Opening Sweeps and OPG Orders entered in the Opening Process, which is 
described in Options 3, Section 8, and would assist Members in managing 
their pre-open risk by allowing Members to adhere to their firm 
thresholds. The Exchange is providing both order and quote risk 
protections in the Opening Process to allow Members to manage their 
risk. The Exchange notes that other risk protections within Options 3, 
Section 15 do not apply to either an Opening Sweep or an Opening Only 
Order because the risk protection either relies on the BBO, which is 
available after the Opening Process or the risk protection is optional.
Options 3, Sections 11 and 13
    The Exchange's proposal to amend Options 3, Section 11(b)(4)(A) 
related to the Facilitation Mechanism is consistent with the Act and 
the protection of investors and the general public because the System 
ensures that the facilitation order is at a price that is not inferior 
to the Exchange best bid (offer) or if there is a Priority Customer on 
the same side Exchange best bid (offer) at the same price as the 
facilitation price, otherwise

[[Page 66109]]

the order would be cancelled. This price check ensures that the auction 
order may not trade at or through the Priority Customer order on the 
same side. This language represents the current System functionality. 
Similar changes are proposed to Options 3, Section 11(d)(3)(A) related 
to the Solicited Order Mechanism, and Options 3, Section 11(e)(4)(A) 
related to the Complex Solicited Order Mechanism with respect to the 
contra-side. These amendments represent current System functionality 
and similarly ensure that the auction order may not trade at or through 
the Priority Customer order on the contra side. This is consistent with 
the treatment of Priority Customer in ISE's order book allocation, 
described in Options 3, Section 10, wherein Priority Customer interest 
is executed within PIM ahead of any other interest of Members.\12\
---------------------------------------------------------------------------

    \12\ See also ISE Options 3, Section 13(d)(1), ``At a given 
price, `Priority Customer Interest' (Priority Customer Orders and 
Improvement Orders from Priority Customers) is executed in full 
before `non-Priority Customer Interest' (non-Priority Customer 
Orders, Improvement Orders from non-Priority Customers and Market 
Maker quotes).''
---------------------------------------------------------------------------

    The Exchange's proposal to amend new Options 3, Section 
11(b)(4)(iv) related to the Facilitation Mechanism, Options 3, Section 
11(c)(7)(E) related to the Complex Facilitation Mechanism, Options 3, 
Section 13(d)(7) related to the Price Improvement Mechanism for 
Crossing Transactions, and Options 3, Section 13(e)(5)(vi) related to 
the Complex Price Improvement Mechanism is consistent with the Act and 
the protection of investors and the general public by permitting 
rounding to occur as specified in the Exchange's rules. The proposal 
states how rounding interacts with the allocation percentages. The 
Exchange proposes to state that it will not permit an allocation 
percentage greater than the stated amounts in the auction rules, unless 
rounding is necessary. The proposed language represents the current 
System functionality.
    The Exchange's proposal to amend Supplementary Material .04 to 
Options 3, Section 11 to replace the word ``quotes'' with ``Responses'' 
in the Split Price description is consistent with the Act and the 
protection of investors and the general public because orders and 
Responses in the market that receive the benefit of the facilitation 
price may receive executions at Split Prices. This change to the rule 
text is intended to utilize the defined term Response which pursuant to 
Options 3, Section 11(b)(3) may be priced at the price of the order to 
be facilitated or at a better price and will only be considered up to 
the size of the order to be facilitated.
    The Exchange's proposal to add a new Supplementary Material .09 to 
Options 3, Section 11 and a new Supplementary Material .10 to Options 
3, Section 13 to provide that if an allocation would result in less 
than one contract, then one contract would be allocated is consistent 
with the Act and the protection of investors and the general public 
because one contract is the minimum unit in which an option may trade 
on ISE. This language represents the current System functionality. Phlx 
has similar language.\13\
---------------------------------------------------------------------------

    \13\ See Phlx Options 3, Section 13(b)(1)(D).
---------------------------------------------------------------------------

    The Exchange's proposal to amend Options 3, Section 13(b)(1) 
through (3) to harmonize the language within the PIM entry checks with 
language within GEMX's PIM, MRX's PIM, Phlx's PIXL and BX's PRISM, 
without changing the substantive operations of these price improvement 
auctions, is consistent with the Act and the protection of investors 
and the general public because by utilizing similar language, Members 
will be able to compare ISE's PIM entry checks with similar mechanisms 
on Nasdaq affiliated markets.
    Amending Options 3, Section 13(b)(1) to add new subparagraphs (A) 
and (B) to distinguish opposite and same side checks and add within the 
same side check a reference to the NBBO check, is consistent with the 
Act and the protection of investors and the general public because the 
NBBO check is always relevant in the same side check to avoid a trade-
through. The Exchange believes that the addition of the NBBO check will 
add clarity to the rule text because the NBBO check is always relevant 
in the same side check to avoid a trade-through. The remainder of the 
changes are non-substantive.
    The Exchange's proposal to bifurcate the entry check for Agency 
Orders of 50 options contracts or more for the account of a Priority 
Customer from the entry checks for the account of a broker dealer or 
any other person or entity that is not a Priority Customer into two new 
paragraphs, a (b)(2) and a (b)(3), is consistent with the Act and the 
protection of investors and the general public because retaining the 
same rule text format across its Nasdaq affiliated markets will allow 
for an easier comparison.
    The Exchange's proposal to add ``for the account of a Priority 
Customer'' to new subparagraph (b)(2) to explicitly address the 
opposite side of the market and also note the NBBO entry check on the 
same side of the market is consistent with the Act and the protection 
of investors and the general public because the new format will provide 
the parameters for each check. Further, the NBBO check is always 
relevant in the same side check to avoid a trade-through. The remainder 
of the changes are non-substantive. Mirroring the same language within 
Options 3, Section 13(b)(2)(B), except to note that it is for the 
account of a broker dealer or any other person or entity that is not a 
Priority Customer will allow Members to compare ISE's PIM entry checks 
with similar mechanisms on Nasdaq affiliated markets.
    The Exchange's proposal to add a new Options 3, Section 
13(e)(5)(vii) for Complex PIM Orders is consistent with the Act and the 
protection of investors and the general public because it ensures the 
Complex PIM would not execute at a price that trades at or through the 
Complex Order's limit price. Today, the rule text does not specify the 
price at which an Agency Complex Order may execute. The Exchange notes 
that there are no Priority Customer overlays in Options 3, Section 
14(d)(2) and therefore, the Agency Complex Order may be executed at a 
price that is equal to the resting Complex Order's limit price. Phlx 
has substantially similar rule text at Options 3, Section 13(b)(8).

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.
Options 3, Section 7
Opening Only
    The Exchange's proposal to amend Options 3, Section 7(u), Opening 
Sweeps and Supplementary Material .02(e) to Options 3, Section 7 
related to OPG Orders does not impose an intra-market burden on 
competition because the Market Wide Risk Protection is available to all 
Members in the Opening Process. The Exchange's proposal to amend 
Opening Sweeps and OPG Orders does not impose an inter-market burden on 
competition because other options exchanges may similarly offer such 
risk protections on their opening order types.
Options 3, Sections 11 and 13
    The Exchange's proposal to amend Options 3, Section 11(b)(4)(A) 
related to the Facilitation Mechanism, Options 3, Section 11(d)(3)(A) 
related to the Solicited Order Mechanism, and Options 3, Section 
11(e)(4)(A) related to the Complex Solicited Order

[[Page 66110]]

Mechanism to state that that the order must execute at a price that is 
better than the same side BBO if these is a Priority Customer on the 
same side does not impose an intra-market burden on competition because 
all auction orders in these aforementioned auction mechanisms would be 
handled in a uniform manner by the System such that those orders would 
not be permitted to trade at or through the Priority Customer order on 
the same side. The Exchange's proposal to amend Options 3, Section 
11(b)(4)(A) related to the Facilitation Mechanism, Options 3, Section 
11(d)(3)(A) related to the Solicited Order Mechanism, and Options 3, 
Section 11(e)(4)(A) related to the Complex Solicited Order Mechanism to 
make clear that that the order must execute at a price that is better 
than the same side BBO if these is a Priority Customer on the same side 
does not impose an inter-market burden on competition because other 
options markets similarly have customer overlay priorities.
    The Exchange's proposal to amend new Options 3, Section 
11(b)(4)(iv) related to the Facilitation Mechanism, Options 3, Section 
11(c)(7)(E) related to the Complex Facilitation Mechanism, Options 3, 
Section 13(d)(7) related to the Price Improvement Mechanism for 
Crossing Transactions, and Options 3, Section 13(e)(5)(vi) related to 
the Complex Price Improvement Mechanism does not impose an intra-market 
burden on competition because the Exchange's rules regarding rounding 
are applied in a uniform manner to all Members submitting an order into 
an auction mechanism. The Exchange's proposal to amend new Options 3, 
Section 11(b)(4)(iv) related to the Facilitation Mechanism, Options 3, 
Section 11(c)(7)(E) related to the Complex Facilitation Mechanism, 
Options 3, Section 13(d)(7) related to the Price Improvement Mechanism 
for Crossing Transactions, and Options 3, Section 13(e)(5)(vi) related 
to the Complex Price Improvement Mechanism does not impose an inter-
market burden on competition because other options exchanges similarly 
round in excess of allocation percentages such as BX.\14\

    The Exchange's proposal to amend Supplementary Material .04 to 
Options 3, Section 11 to replace the word ``quotes'' with ``Responses'' 
in the Split Price description does not impose an intra-market burden 
on competition because orders and responses in the market that receive 
the benefit of the facilitation price may receive executions at Split 
Prices. This clarification to the rule text is intended to correct the 
current language. The Exchange's proposal to amend Supplementary 
Material .04 to Options 3, Section 11 to replace the word ``quotes'' 
with ``Responses'' in the Split Price description does not impose an 
inter-market burden on competition because this rule text change is 
specific to ISE's rule language.
    The Exchange's proposal to add a new Supplementary Material .09 to 
Options 3, Section 11 and a new Supplementary Material .10 to Options 
3, Section 13 to provide that, today, if an allocation would result in 
less than one contract, then one contract will be allocated does not 
impose an intra-market burden on competition because the System would 
uniformly allocate contracts with a minimum unit of one contract. The 
Exchange's proposal to add a new Supplementary Material .09 to Options 
3, Section 11 and a new Supplementary Material .10 to Options 3, 
Section 13 to provide that, today, if an allocation would result in 
less than one contract, then one contract will be allocated does not 
impose an inter-market burden on competition because other options 
markets similarly specify a minimum unit of rounding such as Phlx.\15\

---------------------------------------------------------------------------

    The Exchange's proposal to amend Options 3, Section 13(b)(1) 
through (3) to harmonize the language within the PIM entry checks 
within GEMX's PIM, MRX's PIM, Phlx's PIXL and BX's PRISM, without 
changing the substantive operations of these price improvement 
auctions, distinguishing opposite and same side checks, and adding the 
NBBO check reference within the same side check do not impose an intra-
market undue burden on competition because harmonizing the language 
will enable Members to compare ISE's PIM entry checks with similar 
mechanisms on Nasdaq affiliated markets. Further, the NBBO check is 
always relevant in the same side check to avoid a trade-through. The 
Exchange's proposal to amend Options 3, Section 13(b)(1) through (3) to 
harmonize the language within the PIM entry checks within GEMX's PIM, 
MRX's PIM, Phlx's PIXL and BX's PRISM, without changing the substantive 
operations of these price improvement auctions, distinguishing opposite 
and same side checks, and adding the NBBO check reference within the 
same side check do not impose an inter-market undue burden on 
competition because other options markets have their own price 
improvement auctions and are free to denote their entry checks in a 
similar fashion and have both same and opposite side entry checks which 
may differ from ISE's rule.
    The Exchange's proposal to add a new Options 3, Section 
13(e)(5)(vii) for Complex Orders does not impose an intra-market undue 
burden on competition because the Exchange would uniformly apply the 
price check for the Agency Complex Orders such that the Agency Complex 
Order may be executed at a price that is equal to the resting Complex 
Order's limit price. The Exchange's proposal to add a new Options 3, 
Section 13(e)(5)(vii) for Complex Orders does not impose an inter-
market undue burden on competition because the price check is similar 
to price checks on other options markets such as Phlx.\16\

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 become 
effective pursuant to Section 19(b)(3)(A)(iii) of the Act \17\ and 
subparagraph (f)(6) of Rule 19b-4 thereunder.\18\
---------------------------------------------------------------------------

    \17\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \18\ 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.
---------------------------------------------------------------------------

    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.
