of Amendment No. 1 and Order Granting Accelerated Approval of a 
Proposed Rule Change, as Modified by Amendment No. 1, To Adopt Rules To

I. Self-Regulatory Organization's Description of the Proposed Rule 
Change, as Modified by Amendment No. 1 <SUP>10</SUP>
---------------------------------------------------------------------------

    \10\ This Section I and II reproduces Amendment No. 1, as filed 
by the Exchange.
---------------------------------------------------------------------------

    The Exchange proposes to adopt rules that will govern the listing 
and trading of flexible exchange options (``FLEX Options''). This 
Amendment No. 1 supersedes the original filing in its entirety.
    The text of the proposed rule change is available on the Exchange's 
website at <a href="https://listingcenter.nasdaq.com/rulebook/ise/rules">https://listingcenter.nasdaq.com/rulebook/ise/rules</a>, 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 adopt rules in new Options 3A that will 
govern the listing and trading of FLEX Options on the Exchange's 
electronic market. This Amendment No. 1 supersedes the original filing 
in its entirety, and is being filed to better align the proposed rule 
change with the rules of other exchanges and provide more clarity to 
the proposed rule text as well as the description of and statutory 
basis for the proposed rule change. As discussed in further detail 
later in this filing, Amendment No. 1 makes a number of clarifying 
changes to the proposed rule text as well as the following more 
substantive rule text changes from the original filing: (i) excluding 
the iShares Bitcoin Trust ETF from FLEX trading in proposed Options 3A, 
Section 3(a); (ii) clarifying in proposed Options 3A, Section 3(b)(2) 
that on the expiration date, a FLEX Order for the expiring FLEX Option 
series may only be submitted to close out a position in such expiring 
FLEX Option series; (iii) aligning the Exchange's closing only 
provisions in proposed Options 3A, Section 3(d)(2) to already effective 
rules of other options exchanges; (iv) clarifying in proposed Options 
3A, Section 5 which provisions will govern how the minimum increments 
for complex FLEX Orders (including complex FLEX Orders with a stock 
component) will be handled; (v) clarifying in proposed Options 3A, 
Sections 6(a) and 6(b) that only the specified order types, times-in-
force, and order and quote protocols are available for FLEX trading; 
(vi) removing in proposed Options 3A, Section 7(b) the Exchange's 
discretion to determine on a class-by-class basis which complex FLEX 
Orders would not have to adhere to the ratio requirements for the 
standard complex market; (vii) adding language in proposed Options 3A, 
Section 11(a)(2)(A) to describe what would happen if there is a complex 
FLEX Order and subsequently, a non-FLEX Option series is introduced for 
the component leg(s), which would align to already effective rules of 
another options exchange; (viii) adding language in proposed Options 
3A, Sections 12(a)(2) and 13(a)(2) that each leg of a complex FLEX 
Order must be in a permissible FLEX option series that complies with 
proposed Options 3; (ix) specifying in proposed Options 3A, Section 
13(a)(4) that the minimum size requirement will apply to each leg of a 
complex FLEX Order; (x) adding in proposed Options 3A, Section 14(b) 
that the Price Limit for Complex Order protections as applicable to the 
stock component, the Stock-Tied NBBO protections, and the Stock-Tied 
Reg SHO protections will also be available to FLEX Options as complex 
order risk protections; and (xi) aligning the proposed position limits 
for FLEX Index Options in proposed Options 3A, Section 18(a) with the 
position limits for index options in the Exchange's standard index 
options market.
    The Exchange notes that Amendment No. 1 is solely intended to 
further clarify the proposed rule text and conform the rule text with 
the already

[[Page 94987]]

established rules of other exchanges, and to provide additional detail 
and specificity with respect to the proposed rule change and additional 
information in support of the purpose and statutory basis for the 
proposed rule change.
Summary
    The Exchange is proposing this new functionality be implemented in 
connection with a technology migration to enhanced Nasdaq, Inc. 
(``Nasdaq'') functionality that will result in higher performance, 
scalability, and more robust architecture, which will be implemented as 
a day 2 change after the first phase of the system migration was 
implemented in September 2024.\11\ The Exchange intends to begin 
implementation of the proposed rule change by May 12, 2025. The delayed 
implementation of the proposed FLEX rules will ensure that the Exchange 
will have the necessary functionality in place to trade FLEX. The 
Exchange will issue a public notice to Exchange members (``Members'') 
to provide notification of the FLEX implementation date and highlight 
the features for FLEX proposed hereunder.
---------------------------------------------------------------------------

    \11\ The Exchange separately proposed a number of rule filings 
in connection with this technology migration. See Securities 
Exchange Act Release Nos. 94897 (May 12, 2022), 87 FR 30294 (May 18, 
2022) (SR-ISE-2022-11); 96362 (November 18, 2022), 87 FR 72539 
(November 25, 2022) (SR-ISE-2022-25); 96518 (December 16, 2022), 87 
FR 78740 (December 22, 2022) (SR-ISE-2022-28); 96818 (February 6, 
2023), 88 FR 8950 (February 10, 2023) (SR-ISE-2023-06); 97605 (May 
26, 2023), 88 FR 36350 (June 2, 2023) (SR-ISE-2023-10); 98066 
(August 7, 2023), 88 FR 54672 (August 11, 2023) (SR-ISE-2023-13); 
98443 (September 20, 2023), 88 FR 66106 (September 26, 2023) (SR-
ISE-2023-19); and 98702 (October 6, 2023), 88 FR 71046 (October 13, 
2023) (SR-ISE-2023-22). As per the previously announced technology 
migration, ISE completed its symbol migration on September 23, 2024. 
See <a href="https://www.nasdaqtrader.com/MicroNews.aspx?id=OTA2024-1">https://www.nasdaqtrader.com/MicroNews.aspx?id=OTA2024-1</a>. As a 
result and prior to any FLEX trading on ISE, the foregoing rule 
changes are currently all effective and operative.
---------------------------------------------------------------------------

    As proposed, FLEX Options will be customized options contracts that 
will allow investors to tailor contract terms for exchange-listed 
equity and index options. FLEX Options will be designed to meet the 
needs of investors for greater flexibility in selecting the terms of 
options within the parameters of the Exchange's proposed rules. FLEX 
Options will not be preestablished for trading and will not be listed 
individually for trading on the Exchange. Rather, investors will select 
FLEX Option terms and will be limited by the parameters detailed below 
in their selection of those terms. As a result, FLEX Options would 
allow investors to specify more specific, individualized investment 
objectives than may be available to them in the standardized options 
market.
    Some key features of the new electronic FLEX Options functionality 
are as follows:
    <bullet> System Availability: The Exchange will not conduct an 
Opening Process pursuant to Options 3, Section 8 in FLEX Options.\12\ 
Orders in FLEX Options may only be submitted through an electronic FLEX 
Auction, a FLEX Price Improvement Auction (``FLEX PIM''), or a FLEX 
Solicited Order Mechanism (``FLEX SOM''), each as discussed in detail 
below.\13\ Accordingly, the Exchange's simple and complex order books 
will not be available for transactions in FLEX Options.\14\
---------------------------------------------------------------------------

    \12\ See proposed Options 3A, Section 8(a). Rather, Members may 
begin submitting orders in FLEX Options into one of the proposed 
auction mechanisms (i.e., electronic FLEX Auction, FLEX Price 
Improvement Mechanism, and FLEX Solicited Order Mechanism) once the 
underlying security is open for trading. See proposed Options 3A, 
Section 8(b).
    \13\ See proposed Options 3A, Section 11(a).
    \14\ See proposed Options 3A, Section 10(a).
---------------------------------------------------------------------------

    <bullet> Terms: FLEX Options will be a type of put or call, and 
will allow investors the flexibility to choose an exercise style of 
American or European, an expiration date, a settlement type, and an 
exercise price, all within the parameters specified in the proposed 
rules.\15\ As discussed further below, FLEX Options will not be 
permitted with identical terms as an existing non-FLEX Option series 
listed on the Exchange.\16\
---------------------------------------------------------------------------

    \15\ As discussed later in this filing, proposed Options 3A, 
Section 3(c) will govern FLEX Options terms.
    \16\ At least one of the following terms must differ between 
FLEX Options and non-FLEX Options on the same underlying security: 
exercise date, exercise price, or exercise style. See proposed 
Options 3A, Section 3(c).
---------------------------------------------------------------------------

    <bullet> Priority: As discussed in detail below within the 
respective sections for FLEX Auctions, FLEX PIM, and FLEX SOM, the 
Exchange will apply the same priority order for FLEX Options as it 
applies today in its standard non-FLEX market, particularly in its 
standard auction mechanisms such as its standard Solicited Order 
Mechanism and standard Price Improvement Mechanism. Specifically, the 
System \17\ shall execute trading interest at the best price level 
within the System before executing at the next best price. Priority 
Customers shall have priority over non-Priority Customer interest at 
the same price with time priority meaning that priority shall be 
afforded to Priority Customer orders in the sequence in which they are 
received by the System. As set out in Options 1, Section 1(a)(37), the 
term ``Priority Customer'' means a person or entity that (i) is not a 
broker or dealer in securities, and (ii) does not place more than 390 
orders in listed options per day on average during a calendar month for 
its own beneficial account(s).
---------------------------------------------------------------------------

    \17\ The term ``System'' means the electronic system operated by 
the Exchange that receives and disseminates quotes, executes orders 
and reports transactions. See Options 1, Section 1(a)(50).
---------------------------------------------------------------------------

    Because of their composition, the Exchange believes that FLEX 
Options may allow investors to more closely meet their individual 
investment and hedging objectives by customizing options contracts for 
the purpose of satisfying particular investment objectives that could 
not be met by the standardized markets.
Background
    The Commission approved the trading of FLEX Options in 1993.\18\ At 
the time, the Chicago Board Options Exchange, Inc., now Cboe Exchange, 
Inc. (``Cboe''), proposed FLEX Options based on the Standard and Poor's 
Corporation 500 and 100 Stock Indexes.\19\ These FLEX Options were 
offered as an alternative to an over-the-counter (``OTC'') market in 
customized equity options.\20\ Several years after the initial 
approval, the Commission approved the trading of additional FLEX 
Options on specified equity securities.\21\ In its order, the 
Commission provided: ``The benefits of the Exchanges' options markets 
include, but are not limited to, a centralized market center, an 
auction market with posted transparent market quotations and 
transaction reporting, parameters and procedures for clearance and 
settlement, and the guarantee of the OCC [Options Clearing Corporation] 
for all contracts traded on the Exchange.'' \22\
---------------------------------------------------------------------------

    \18\ See Securities Exchange Act Release No. 31920 (February 24, 
1993), 58 FR 12280 (March 3, 1993) (SR-CBOE-92-17) (Order Approving 
and Notice of Filing and Order Granting Accelerated Approval to 
Amendment Nos. 1, 2, 3, and 4 to Proposed Rule Changes by the 
Chicago Board Options Exchange, Inc., Relating to FLEX Options).

(Order Approving Proposed Rule Changes and Notice of Filing and 
Order Granting Accelerated Approval of Amendments by the Chicago 
Board Options Exchange, Inc. and the Pacific Stock Exchange, Inc., 
Relating to the Listing of Flexible Exchange Options on Specified 
Equity Securities).
    \22\ Id. The Exchange notes that the Commission found pursuant 
to Rule 9b-1 under the Act, that FLEX Options, including FLEX Equity 
Options, are standardized options for purposes of the options 
disclosure framework established under Rule 9b-1 of the Act. Id.
---------------------------------------------------------------------------

    The Exchange notes that FLEX Options are currently traded on Cboe, 
NYSE American LLC (``NYSE American''), NYSE Arca, Inc. (``NYSE

[[Page 94988]]

Arca''), Nasdaq PHLX LLC (``Phlx''), and FLEX Equity Options on BOX 
Exchange LLC (``BOX'').\23\ The Exchange further notes that Cboe offers 
electronic and open outcry FLEX Options trading while NYSE American, 
NYSE Arca, Phlx and BOX offer only open outcry trading of FLEX Options 
on their respective trading floors.\24\ The Exchange now proposes to 
allow for the trading of FLEX Options on its electronic market \25\ in 
a substantially similar manner as Cboe's electronic FLEX Options, with 
certain intended differences primarily to align to current System 
behavior (and especially current auction behavior) to provide increased 
consistency for Members trading FLEX Options and non-FLEX Options on 
ISE, as discussed in detail below. Further, the Exchange has omitted 
certain Cboe rules from the proposed rules due to differences in scope 
and operation of FLEX trading at Cboe compared to the proposed scope 
and operation of FLEX trading on ISE, each as noted below. For example, 
the Exchange will not include Cboe rule provisions related to open 
outcry trading, Asian- or Cliquet-settled FLEX index options, or FLEX 
index options with an index multiplier of one (``Micro FLEX Index 
Options'') as it does not offer these capabilities today. For the same 
reason, the Exchange will not allow prices in FLEX trading to be 
expressed as percentages under this proposal. The Exchange also will 
not incorporate the concept of a ``FLEX Official'' as this is a floor 
concept and the Exchange does not have a trading floor. As such, 
instead of nullifying FLEX Option transactions that do not conform to 
the terms of the Exchange's proposed FLEX rules,\26\ the Exchange will 
System enforce its proposed FLEX rules and reject at the outset a FLEX 
Option transaction that does not conform to the terms of the proposed 
FLEX rules. The very few instances where the Exchange will not System-
enforce the proposed FLEX rules and will instead apply its surveillance 
patterns will be specifically noted below.
---------------------------------------------------------------------------

    \23\ See Cboe Rules 4.20-4.22 and 5.70-5.75, NYSE American Rules 
900G-910G, NYSE Arca Rules 5.30-O-5.41-O, Phlx Options 8, Section 
34, and BOX Rules 5055 and 7605. The Exchange also notes that BOX 
recently received approval from the Commission to allow for the 
trading of FLEX equity options on the BOX trading floor. See 
Securities Exchange Act Release No. 100156 (May 15, 2024), 89 FR 
44721 (May 21, 2024) (SR-BOX-2023-20).
    \24\ See supra note 23.
    \25\ The Exchange is not proposing to add open outcry FLEX 
Options trading as it does not have a trading floor.
    \26\ Cboe Rule 5.75(b) sets forth the responsibilities of FLEX 
Officials, including the responsibility to nullify certain FLEX 
Option transactions that do not conform to Cboe's FLEX rules, and to 
call upon a FLEX Market-Maker with an appointment in a FLEX Option 
class to respond to open outcry FLEX Auctions in that FLEX Option 
class when no other ICMPs respond. The Exchange will not adopt these 
provisions because a FLEX Official is a floor concept and Exchange 
does not have a trading floor (and therefore no open outcry 
auctions).
---------------------------------------------------------------------------

Proposal
    Transactions in FLEX Options traded on the Exchange will generally 
be subject to the same rules that apply to the trading of equity 
options and index options. In order, however, to provide investors with 
the flexibility to designate certain of the terms of the options, and 
to accommodate other special features of FLEX Options and the way in 
which they are traded, the Exchange proposes new rules applicable to 
FLEX Options in new Options 3A, Sections 1-19.

A. General Provisions (Section 1)

    Proposed Section 1(a) will set forth the applicability of Exchange 
Rules, and will provide that Options 3A Rules will apply only to FLEX 
Options and that trading of FLEX Options will be subject to all other 
Rules applicable to the trading of options on the Exchange, unless 
otherwise provided in Options 3A. The Exchange has conducted a thorough 
review of its existing trading rules to ensure that the proposed Rules 
in Options 3A accurately reflects the application of the Exchange's 
non-FLEX Option trading rules to FLEX Options,\27\ as well as those 
non-FLEX Option trading rules that would not apply to FLEX Options.\28\
---------------------------------------------------------------------------

    \27\ For example, Options 3, Section 1 (Hours of Business) will 
apply to FLEX and non-FLEX Options, except the Exchange may 
determine to narrow or otherwise restrict the trading hours for FLEX 
Options. See proposed Options 3A, Section 2. As another example, 
Options 3, Section 9 (Trading Halts) will apply to FLEX and non-FLEX 
Options. The Exchange notes that pursuant to proposed Options 3A, 
Section 9, it will always halt trading in a FLEX Option class when 
trading in a non-FLEX Option class with the same underlying equity 
security or index is halted on the Exchange. Furthermore, the System 
does not accept a FLEX Order for a FLEX Option series while trading 
in a FLEX Option class is halted.
    \28\ For example, the Exchange's simple and complex order books 
will not be available for transactions in FLEX Options. See proposed 
Options 3A, Section 10. In addition, FLEX Options may not trade via 
the Block Order Mechanism (Options 3, Section 11(a)), simple and 
complex Facilitation Mechanism (Options 3, Section 11(b) and (c)), 
or as simple and complex Customer Cross Orders (Options 3, Section 
12(a) and (b)), simple and complex Qualified Contingent Cross 
(``QCC'') Orders (Options 3, Section 12(c) and (d)), and simple and 
complex QCC with Stock Orders (Options 3, Section 12(e) and (f))). 
If the Exchange intends to allow FLEX Options to trade via any of 
the foregoing auction mechanisms or as any of the foregoing crossing 
orders, the Exchange would be required to file a proposed rule 
change with the Commission to amend its FLEX rules to allow for the 
use of the foregoing trading functionality for FLEX Options.
---------------------------------------------------------------------------

    Proposed Section 1(b) will set forth the definitions used 
specifically in Options 3A, namely that the term ``FLEX Option'' means 
a flexible exchange option. A FLEX Option on an equity security may be 
referred to as a ``FLEX Equity Option,'' and a FLEX Option on an index 
may be referred to as a ``FLEX Index Option.'' Further, the term ``FLEX 
Order'' means an order submitted in a FLEX Option pursuant to Options 
3A.
    The Exchange also proposes to add the definition of ``FLEX Order'' 
in Options 3, Section 7 (Order Types) in new paragraph (z). While FLEX 
Orders will also be defined in (and governed by) Options 3A, the 
Exchange believes that it will be useful to market participants to have 
the order types available on ISE centralized within one rule. Lastly, 
the Exchange proposes a non-substantive change to paragraph (y) in 
Options 3, Section 7 to fix a typo.

B. Hours of Business (Section 2)

    Proposed Section 2(a) will provide that the trading hours for FLEX 
Options will be the same as the trading hours for corresponding non-
FLEX Options as set forth in Options 3, Section 1, except the Exchange 
may determine to narrow or otherwise restrict the trading hours for 
FLEX Options.\29\ Therefore, the trading hours for FLEX Options will 
generally be 9:30 a.m. to 4:00 p.m. Eastern time, except for certain 
options products that trade until 4:15 p.m. Eastern time.\30\ This 
would align the proposed trading hours for FLEX Options with the 
current trading hours for corresponding non-FLEX Options.
---------------------------------------------------------------------------

    \29\ See Cboe Rule 5.1(b)(3)(A) for materially identical 
provisions.
    \30\ See Options 3, Section 1(c)-(e). These products are 
currently options on Exchange-Traded Fund Shares (as defined in 
Options 4, Section 3(h), options on Index-Linked Securities (as 
defined in Options 4, Section 3(k)(1)), and options on certain 
broad-based indexes, as designated by the Exchange.
---------------------------------------------------------------------------

    As it relates to the Exchange's proposed discretion relating to the 
trading hours for FLEX Options, this is consistent with Cboe's FLEX 
Options rules as noted above. The Exchange believes that given the 
unique nature of FLEX, in contrast to the non-FLEX market, it is 
reasonable to permit the Exchange, in its discretion, to narrow or 
otherwise restrict the trading hours for FLEX Options, so long as such 
trading hours occur within the normal options trading hours of the 
Exchange described above. The Exchange would provide adequate advance 
notification to its Members of such changes in FLEX trading hours.

[[Page 94989]]

C. FLEX Option Classes and Permissible Series (Section 3(a) and (b))

    Pursuant to proposed Section 3(a), the Exchange may authorize for 
trading a FLEX Option class on any equity security (except the iShares 
Bitcoin Trust ETF) or index if it may authorize for trading a non-FLEX 
Option class on that equity security or index pursuant to Options 4, 
Section 3 and Options 4A, Section 3,\31\ respectively, even if the 
Exchange does not list that non-FLEX Option class for trading.\32\ The 
Exchange proposes to exclude iShares Bitcoin Trust ETF (``IBIT'') from 
being eligible for trading as a FLEX Option on ISE to be consistent 
with the Commission's approval of IBIT options, which required the 
position limit for IBIT options to be 25,000 contracts.\33\ As 
discussed in the position limits section below, there will generally be 
no position limits for FLEX Equity Options.\34\ The Exchange therefore 
proposes to exclude IBIT options from being eligible to trade as a FLEX 
Option (namely, a FLEX ETF option) to continue to limit the position 
limits for IBIT options. For clarity, this exclusion will apply to both 
physically-settled and cash-settled FLEX ETF options (as further 
described in this filing), such that IBIT options will be excluded from 
being eligible to trade as a physically-settled or a cash-settled FLEX 
ETF option. If the Exchange determines to allow FLEX trading on IBIT 
options at a later date, it will do so by submitting a 19b-4 rule 
filing with the Commission.
---------------------------------------------------------------------------

    \31\ Options 4, Section 3 provides the criteria for the listing 
of options on several different underlying types of securities, 
including, for example, securities registered with the SEC under 
Regulation NMS of the Act (``NMS stock'') and exchange-traded funds 
(``ETFs''). Options 4A, Section provides the criteria for the 
listing of options on indexes.
    \32\ See Cboe Rule 4.20 for materially identical provisions.
    \33\ See Securities Exchange Act Release No. 101128 (September 
20, 2024), 89 FR 78942 (September 26, 2024) (SR-ISE-2024-03).
    \34\ See proposed Options 3A, Section 18(b)(1)(A).
---------------------------------------------------------------------------

    Proposed Section 3(b) will provide that the Exchange may approve a 
FLEX Option series for trading in any FLEX Option class it may 
authorize for trading pursuant to proposed Section 3(a). FLEX Option 
series are not pre-established. A FLEX Option series is eligible for 
trading on the Exchange upon submission to the System of a FLEX Order 
for that series pursuant to proposed Sections 11 through 13,\35\ 
subject to the following stipulations.\36\ First, the Exchange will 
only permit trading in a put or call FLEX Option series that does not 
have the same exercise style, same expiration date, and same exercise 
price as a non-FLEX Option series on the same underlying security or 
index that is already available for trading. This would include 
permitting trading in a FLEX Option series before a series with 
identical terms is listed for trading as a non-FLEX Option series. If 
the Exchange lists for trading a non-FLEX Option series with identical 
terms as a FLEX Option series, the FLEX Option series will become 
fungible with the non-FLEX Option series pursuant to proposed paragraph 
(d) of Section 3. The System would not accept a FLEX Order for a put or 
call FLEX Option series if a non-FLEX Option series on the same 
underlying security or index with the same expiration date, exercise 
price, and exercise style is already listed for trading.\37\ Second, a 
FLEX Order for a FLEX Option series may be submitted on any trading day 
prior to the expiration date.\38\ The Exchange also proposes to clarify 
in proposed Section 3(b)(2) that on the expiration date, a FLEX Order 
for the expiring FLEX Option series may only be submitted to close out 
a position in such expiring FLEX Option series.\39\
---------------------------------------------------------------------------

    \35\ Proposed Sections 11 through 13 of Options 3A will govern 
the electronic FLEX Auction, FLEX PIM, and FLEX SOM, respectively. 
As discussed later in this filing, FLEX Orders may only be submitted 
through an electronic FLEX Auction, FLEX PIM, or FLEX SOM.
    \36\ See proposed Options 3A, Section 3(b), which is based on 
Cboe Rule 4.21(a).
    \37\ See proposed Options 3A, Section 3(b)(1), which is based on 
Cboe Rule 4.21(a)(1).
    \38\ See proposed Options 3A, Section 3(b)(2), which is based on 
Cboe Rule 4.21(a)(2). The Exchange notes that it will System enforce 
which options are eligible to be submitted as FLEX Options. As such, 
the System will reject at the outset a FLEX Option transaction that 
does not conform to the terms of the FLEX rules.
    \39\ The Exchange will System enforce this provision such that 
it will reject an opening position in an expiring FLEX Option series 
on the day of expiration.
---------------------------------------------------------------------------

    Third, in the event the relevant expiration is a holiday pursuant 
to General 3 (which incorporates Nasdaq General 3, Rule 1030 by 
reference),\40\ proposed Section 3(d) will apply to options with an 
expiration date that is the business day immediately preceding the 
holiday, except for Monday-expiring Weekly Expirations (as defined in 
Options 4A, Section 3), in which case proposed Section 3(d) will apply 
to options with an expiration date that is a business day immediately 
following the holiday.\41\
---------------------------------------------------------------------------

    \40\ ISE General 3 incorporates by reference Series 1000 in 
General 3 of the Rules of The Nasdaq Stock Market, LLC (``Nasdaq'') 
(including Nasdaq Rule 1030).
    \41\ See proposed Options 3A, Section 3(b)(3), which is based on 
Cboe Rule 4.22(c).
---------------------------------------------------------------------------

D. FLEX Options Terms (Section 3(c))

    Proposed Section 3(c) will specify the terms that must be included 
in a FLEX Order.\42\ Specifically, when submitting a FLEX Order for a 
FLEX Option series to the System, the submitting Member must include 
one of each of the terms detailed in proposed subparagraphs (1)-(6) of 
Section 3(c) in the FLEX Order (all other terms of a FLEX Option series 
are the same as those that apply to non-FLEX Options), provided that a 
FLEX Equity Option overlying an ETF (cash- or physically-settled) may 
not be the same type (put or call) and may not have the same exercise 
style, expiration date, and exercise price as a non-FLEX Equity Option 
overlying the same ETF,\43\ which terms constitute the FLEX Option 
series.
---------------------------------------------------------------------------

    \42\ See Cboe Rule 4.21(b) for similar provisions. The Exchange 
notes that unlike Cboe, it is not proposing FLEX Index Options with 
a multiplier of 1 (i.e., Micro FLEX Index Options) or FLEX Index 
Options that are Asian- or Cliquet-settled as the Exchange does not 
have these capabilities today for index options. For the same 
reason, the Exchange is not proposing to allow exercise prices to be 
expressed as a percentage value. Therefore, the Exchange has not 
incorporated the applicable provisions in this Rule.
    \43\ The Exchange will discuss cash-settled FLEX Equity Options 
overlying an ETF (``cash-settled FLEX ETFs'') later in this filing. 
As discussed below, the Commission previously approved a rule filing 
by NYSE American to permit the listing and trading of this product, 
and Cboe recently filed an immediately effective rule change based 
on NYSE American's filing. See infra notes 243 and 244.
---------------------------------------------------------------------------

    As proposed, the submitting Member must specify the following terms 
in the FLEX Order: (1) underlying equity security or index, as 
applicable (the index multiplier for FLEX Index Options is 100); \44\ 
(2) type of option (i.e., put or call); \45\ (3) exercise style, which 
may be American-style or European-style; \46\ (4) expiration date, 
which may be any business day (specified to the day, month, and year) 
no more than 15 years from the date on which a Member submits a FLEX 
Order to the System; \47\ (5) settlement type for the FLEX Equity 
Option or FLEX Index Option, as applicable; \48\ and (6) exercise

[[Page 94990]]

price, which may be in increments no smaller than $0.01.\49\ Further, 
the Exchange may determine the smallest increment for exercise prices 
of FLEX Options on a class-by-class basis without going lower than 
$0.01.\50\ The Exchange notes that the exercise price of the FLEX 
Option would generally be dependent on the price of the underlying 
security.
---------------------------------------------------------------------------

    \44\ See proposed Options 3A, Section 3(c)(1), which is based on 
Cboe Rule 4.21(b)(1) except for the provisions relating to Micro 
FLEX Index Options.
    \45\ See proposed Options 3A, Section 3(c)(2), which is based on 
Cboe Rule 4.21(b)(2) except the provisions related to Asian-settled 
or Cliquet-settled FLEX Index Options.
    \46\ See proposed Options 3A, Section 3(c)(3), which is based on 
Cboe Rule 4.21(b)(3) except with respect to Asian-settled or 
Cliquet-settled FLEX Index Options.
    \47\ See proposed Options 3A, Section 3(c)(4), which is based on 
Cboe Rule 4.21(b)(4) except with respect to Asian-settled or 
Cliquet-settled FLEX Index Options.
    \48\ See proposed Options 3A, Section 3(c)(5), which is based on 
Cboe Rule 4.21(b)(5) except with respect to Asian-settled or 
Cliquet-settled FLEX Index Options.
    \49\ See proposed Options 3A, Section 3(c)(6), which is based on 
Cboe Rule 4.21(b)(6) except the Exchange is not proposing Cliquet-
settled Index Options or to allow exercise prices to be expressed as 
a percentage value.
    \50\ See proposed Options 3A, Section 3(c), which is based on 
Cboe Rule 4.21(b) except for the provisions allowing the exercise 
price to be expressed as a percentage amount and with respect to 
Micro FLEX Index Options. As noted above, the Exchange does not 
offer these capabilities today for non-FLEX index options. The 
Exchange will also clarify that it would not go lower than $0.01 
when determining the smallest increment for exercise prices of FLEX 
Options to make clear that it would stay within the stated confines 
of this Rule.
---------------------------------------------------------------------------

    As it relates to the settlement type for FLEX Equity Options, the 
Exchange proposes in subparagraph (c)(5)(A)(i) of Options 3A, Section 3 
that FLEX Equity Options, other than as permitted in proposed 
subparagraphs (c)(5)(A)(ii) and (iii), are settled with physical 
delivery of the underlying security. Proposed subparagraph 
(c)(5)(A)(ii) will allow for the cash-settlement of certain qualifying 
FLEX Equity Options with an underlying security that is an ETF.\51\ 
Proposed subparagraph (c)(5)(A)(iii) will provide that FLEX Equity 
Options are subject to the exercise by exception provisions of OCC Rule 
805.
---------------------------------------------------------------------------

    \51\ As discussed later in this filing, the Exchange is 
proposing to list and trade cash-settled FLEX ETFs in the same 
manner as NYSE American and Cboe.
---------------------------------------------------------------------------

    As it relates to the settlement type for FLEX Index Options, the 
Exchange proposes in subparagraphs (c)(5)(B)(i) and (ii) of Options 3A, 
Section 3 that FLEX Index Options are settled in U.S. dollars, and may 
be either a.m.-settled (with exercise settlement value determined by 
reference to the reported level of the index derived from the reported 
opening prices of the component securities) or p.m.-settled (with 
exercise settlement value determined by reference to the reported level 
of the index derived from the reported closing prices of the component 
securities). The Exchange notes that Cboe recently received approval of 
its pilot program that permitted it to list p.m.-settled FLEX Index 
Options whose exercise settlement value is derived from closing prices 
on the last trading day prior to expiration that expire on or within 
two business days of a third Friday-of-the-month expiration day for a 
non-FLEX Option (``FLEX PM Third Friday Options'').\52\ Consistent with 
the Commission's approval of Cboe's proposal, the Exchange is proposing 
to allow the listing of FLEX PM Third Friday Options on ISE as well, 
and will align proposed Section 3(c)(5)(B)(ii) with Cboe Rule 
4.21(b)(5)(B)(ii).\53\
---------------------------------------------------------------------------

    \52\ See Securities Exchange Act Release No. 99222 (December 21, 
2023), 88 FR 89771 (December 28, 2023) (SR-CBOE-2023-018) (``FLEX 
Settlement Pilot Approval''). In support of making the pilot a 
permanent program, Cboe cited to its own review of pilot data during 
the course of the pilot program and a study by the Commission's 
Division of Economic and Risk Analysis (``DERA'') staff. See FLEX 
Settlement Pilot Approval, notes 18 and 35.
    \53\ The only broad-based index option that would be able to 
list as a FLEX PM Third Friday Option is the Nasdaq-100 Index option 
(``NDX'' or ``NDX options'') because the Exchange only received 
approval to list a third-Friday-of-the-month p.m. expiration on NDX 
options its standardized market. See Securities Exchange Act Release 
No. 98935 (November 14, 2023), 88 FR 80792 (November 20, 2023) (SR-
ISE-2023-20) (Order Approving a Proposed Rule Change To Permit the 
Listing and Trading of P.M.-Settled Nasdaq-100 Index Options With a 
Third-Friday-of-the-Month Expiration).
---------------------------------------------------------------------------

E. FLEX Fungibility (Section 3(d))

    Proposed Section 3(d)(1)(A) will provide that if the Exchange lists 
for trading a non-FLEX Option series with identical terms as a FLEX 
Option series, all existing open positions established under the FLEX 
trading procedures will become fully fungible with transactions in the 
identical non-FLEX Option series.\54\ In addition, proposed Section 
3(d)(1)(B) will provide that any further trading in the series would be 
as non-FLEX Options subject to non-FLEX trading procedures and 
Rules.\55\ The foregoing provisions are materially identical to Cboe 
Rule 4.22(a)(1) and (2).
---------------------------------------------------------------------------

    \54\ An open position resulting from a transaction on the 
Exchange becomes fungible post-trade and is separate from the 
execution occurring on the Exchange. For example, assume a Member 
buys one (1) American style AAPL call option expiring on October 9, 
2024, with a strike price of 150, which is a FLEX series because 
there is no standard option listed with those same terms. Now 
assume, while holding this position, a standard option with the same 
terms is listed (American style AAPL call option expiring on October 
9, 2024, with a strike price of 150). After this standard option is 
listed, the Member purchases one (1) contract in this non-FLEX 
option series. After this second transaction, the Participant will 
have an open position of two (2) contracts in the standard AAPL call 
expiring on October 9, 2024, with a 150 strike price.
    \55\ This includes all priority and trade-through provisions on 
the Exchange. See, e.g., Options 3, Section 10 and Options 5, 
Section 2.
---------------------------------------------------------------------------

    Notwithstanding the above, if a non-FLEX Option series \56\ is 
added intraday, for the balance of that trading day, a position 
established under the FLEX trading procedures may be closed using the 
FLEX trading procedures in this Options 3A against another closing only 
FLEX position. No FLEX Orders may be submitted into an electronic 
auction pursuant to Sections 11(b), 12, or 13 below for a FLEX Option 
series with the same terms as the non-FLEX Option series, unless the 
FLEX Order is a closing order, and it is the day on which the non-FLEX 
Option series was added intraday. Members may only submit responses 
that close out existing FLEX positions.\57\ In the event the non-FLEX 
Option series is added on a trading day after the position is 
established, the holder or writer of a FLEX Option position established 
under the FLEX trading procedures would be permitted to close such 
position as a non-FLEX transaction consistent with the requirements of 
subsection (d)(1) of this rule.\58\ The Exchange will notify Members 
when a FLEX Option series is restricted to closing only transactions. 
The System will reject a transaction in such a restricted series that 
does not conform to the requirements specified in proposed Options 3A, 
Section 3(d).\59\
---------------------------------------------------------------------------

    \56\ Cboe Rule 4.22(b)(1) currently indicates that Cboe's 
closing-only provisions apply if a non-FLEX Option American-style 
series is added intraday. The Exchange, however, believes it is more 
straightforward to apply the closing-only provisions to all non-FLEX 
Option series (i.e., American-style and European-style FLEX Option 
series) instead of limiting these provisions to one type of exercise 
style. As such, the Exchange's proposed language in Options 3A, 
Section 3(d)(2)(A) will instead provide that the Exchange's closing-
only provisions would apply ``if a non-FLEX Option is added 
intraday.'' See BOX Rule 7605(d)(3), which similarly does not limit 
BOX's closing-only provisions to American-style FLEX Options series.
    \57\ See proposed Options 3A, Section 3(d)(2)(A), which is based 
on Cboe Rule 4.22(b)(1) except the Exchange is not incorporating 
Cboe's provisions for open outcry trading as the Exchange does not 
offer open outcry trading today. The Exchange is also adding cross-
cites to its electronic FLEX SOM and FLEX PIM auctions in proposed 
Options 3A, Sections 12 and 13 because the closing only provisions 
in proposed Options 3A, Section 3(d)(2) will also apply to those 
electronic FLEX auctions. Lastly, the Exchange notes that unlike 
Cboe, it is not proposing to add FLEX Index Options with a 
multiplier of 1 (i.e., Micro FLEX Index Options) and will therefore 
not incorporate Cboe's closing only language with respect to Micro 
FLEX Index Options in Rule 4.22(b)(2).
    \58\ See proposed Options 3A, Section 3(d)(2)(B), which is 
materially identical to BOX Rule 5055(f)(3). The Exchange is adding 
this language to clarify how it would handle open FLEX positions if 
an identical non-FLEX Option series is added on the day after.
    \59\ See proposed Options 3A, Section 3(d)(2), which is based on 
Cboe Rule 4.22(b), except the Exchange is replacing the concept of 
``FLEX Official'' from Cboe's rule to ``the System'' as a FLEX 
Official is a floor concept. As such, the Exchange will System 
enforce the rejection of FLEX Options that are fully fungible with a 
non-FLEX Option instead of following Cboe, which specifies that a 
FLEX Official could nullify such a transaction on Cboe.
---------------------------------------------------------------------------

F. Units of Trading; Minimum Trading Increments (Sections 4 and 5)

    Proposed Section 4(a) of Options 3A will provide that bids and 
offers for

[[Page 94991]]

FLEX Options must be expressed in U.S. dollars and decimals in the 
minimum increments as set forth in proposed Section 5.\60\ Proposed 
Section 5(a) will provide that the Exchange would determine the minimum 
increment for bids and offers on FLEX Options on a class-by-class 
basis, which may not be smaller than $0.01 for the options leg of a 
FLEX Option.\61\ Proposed Section 5(b) will provide that for the stock 
leg of a FLEX Option, the minimum increments are set forth in Options 
3A, Section 11(b)(1)(G), Section 12(a)(5), and Section 13(a)(5). As 
discussed later in this filing, the foregoing rules specify how minimum 
increments for complex FLEX Orders (including complex FLEX Orders with 
a stock component) would be handled. The Exchange is adding these cross 
cites in the minimum increments rule in proposed Options 3A, Section 
5(b) for transparency and clarity.
---------------------------------------------------------------------------

    \60\ See Cboe Rule 5.3(e)(3) for similar provisions, except the 
Exchange is not proposing to allow prices to be expressed as a 
percentage value, or to provide for Micro FLEX Index Options.
    \61\ See Cboe Rule 5.4(c)(4) for similar provisions, except the 
Exchange is not proposing to allow prices to be expressed as a 
percentage value. The Exchange is also clarifying that this 
provision would apply to the options leg of a FLEX Option.
---------------------------------------------------------------------------

G. Types of Orders; Order and Quote Protocols (Section 6)

    Pursuant to proposed Section 6(a), the Exchange may determine to 
make only the Limit Order and Cancel and Replace Order order types \62\ 
and Immediate or Cancel times-in-force,\63\ respectively, in Options 3, 
Section 7 available on a class or System basis for FLEX Orders.\64\ The 
Exchange notes that it currently has the authority to make certain 
order types and TIFs available on a class or System basis for non-FLEX 
Options pursuant to Options 3, Section 7, and therefore proposes to 
have similar authority with respect to FLEX Options.
---------------------------------------------------------------------------

    \62\ See Options 3, Sections 7(b) and 7(f) for a description of 
Limit Orders and Cancel and Replace Orders, respectively. All of the 
other order types listed in Options 3, Section 7 (such as Customer 
Cross Orders, Qualified Contingent Cross Orders, QCC with Stock 
Orders, Block Orders, and Facilitation Orders) do not apply to FLEX.
    \63\ See Supplementary Material .02(d) to Options 3, Section 7 
for a description of Immediate-or-Cancel. All of the other TIFs in 
Supplementary Material .02 to Options 3, Section 7 will not apply to 
FLEX.
    \64\ See Options 3, Section 7 for descriptions of these order 
types and times-in-force.
---------------------------------------------------------------------------

    Proposed Section 6(b) will provide that only the following order 
and quote protocols in Supplementary Material .03 to Options 3, Section 
7 will be available for FLEX Orders, FLEX auction notifications, and 
FLEX auction responses: \65\
---------------------------------------------------------------------------

    \65\ Notes 58-60 below describe what features are available on 
these protocols today for non-FLEX Options. The Exchange is 
proposing to specify that some of these features (i.e., sending/
receiving FLEX Orders, FLEX notifications and FLEX responses) will 
be available for FLEX Options through the specified protocols as 
described above. While other basic features will be available for 
FLEX Options (for example, the options symbol directory will be 
available for FLEX Options), the Exchange is proposing to specify 
the particular features in proposed Options 3A, Section 6(b) to 
highlight the most important features that would be available 
through these protocols for FLEX trading.
---------------------------------------------------------------------------

    <bullet> FIX: \66\ FLEX Orders and FLEX auction responses
---------------------------------------------------------------------------

    \66\ ``Financial Information eXchange'' or ``FIX'' is an 
interface that allows Members and their Sponsored Customers to 
connect, send, and receive messages related to orders and auction 
orders to the Exchange. Features include the following: (1) 
execution messages; (2) order messages; (3) risk protection triggers 
and cancel notifications; and (4) post trade allocation messages. 
See Supplementary Material .03(a) to Options 3, Section 7.
---------------------------------------------------------------------------

    <bullet> OTTO: \67\ FLEX Orders, FLEX auction notifications, and 
FLEX auction responses
---------------------------------------------------------------------------

    \67\ ``Ouch to Trade Options'' or ``OTTO'' is an interface that 
allows Members and their Sponsored Customers to connect, send, and 
receive messages related to orders, auction orders, and auction 
responses to the Exchange. Features include the following: (1) 
options symbol directory messages (e.g., underlying and complex 
instruments); (2) System event messages (e.g., start of trading 
hours messages and start of opening); (3) trading action messages 
(e.g., halts and resumes); (4) execution messages; (5) order 
messages; (6) risk protection triggers and cancel notifications; (7) 
auction notifications; (8) auction responses; and (9) post trade 
allocation messages. See Supplementary Material .03(b) to Options 3, 
Section 7.
---------------------------------------------------------------------------

    <bullet> SQF: \68\ FLEX auction notifications and FLEX auction 
responses
---------------------------------------------------------------------------

    \68\ ``Specialized Quote Feed'' or ``SQF'' is an interface that 
allows Market Makers to connect, send, and receive messages related 
to quotes, Immediate-or-Cancel Orders, and auction responses to the 
Exchange. Features include the following: (1) options symbol 
directory messages (e.g., underlying and complex instruments); (2) 
System event messages (e.g., start of trading hours messages and 
start of opening); (3) trading action messages (e.g., halts and 
resumes); (4) execution messages; (5) quote messages; (6) Immediate-
or-Cancel Order messages; (7) risk protection triggers and purge 
notifications; (8) opening imbalance messages; (9) auction 
notifications; and (10) auction responses. The SQF Purge Interface 
only receives and notifies of purge requests from the Market Maker. 
Market Makers may only enter interest into SQF in their assigned 
options series. See Supplementary Material .03(c) to Options 3, 
Section 7.
---------------------------------------------------------------------------

H. Complex Orders (Section 7)

    Pursuant to proposed Section 7(a), the Exchange may make complex 
orders, including a Complex Options Order,\69\ Stock-Options Order,\70\ 
and Stock-Complex Order \71\ available for FLEX trading. Complex FLEX 
Orders may have up to the maximum number of legs determined by the 
Exchange.\72\ Each leg of a complex FLEX Order: (1) must be for a FLEX 
Option series authorized for FLEX trading with the same underlying 
equity security or index; (2) must have the same exercise style 
(American or European); and (3) for a FLEX Index Option, may have a 
different settlement type (a.m.-settled or p.m.-settled).\73\ The 
Exchange notes that a non-FLEX complex order can have both am-settled 
and p.m.-settled legs today. The Exchange received approval to permit 
the listing and trading of p.m.-settled NDX options pursuant to 
Supplementary Material .07 to Options 4A, Section 12.\74\ Specifically, 
the Exchange is permitted to list p.m.-settled NDX options that expire 
(1) on any Monday, Tuesday, Wednesday, Thursday, or Friday (other than 
the third Friday-of-the-month or days that coincide with an end-of-
month expiration) \75\ or (2) on the last day of the

[[Page 94992]]

trading month.\76\ In addition, NDX options are also currently allowed 
to be listed as a.m.-settled with a standard expiration (i.e., the 
third-Friday-of-the-month).\77\ Therefore, ISE may currently list NDX 
options that are both a.m.-settled and p.m.-settled for its non-FLEX 
market. As such, the Exchange's FLEX proposal for complex orders in 
this respect will not only align with Cboe's current FLEX complex order 
functionality as noted above,\78\ but will also align with its own 
current non-FLEX complex order functionality.
---------------------------------------------------------------------------

    \69\ A Complex Options Order is an order for a Complex Options 
Strategy, which is the simultaneous purchase and/or sale of two or 
more different options series in the same underlying security, for 
the same account, in a ratio that is equal to or greater than one-
to-three (.333) and less than or equal to three-to-one (3.00) and 
for the purpose of executing a particular investment strategy. See 
Options 3, Section 14(a)(1).
    \70\ A Stock-Option Order is an order for a Stock-Option 
Strategy, which is the purchase or sale of a stated number of units 
of an underlying stock or a security convertible into the underlying 
stock (``convertible security'') coupled with the purchase or sale 
of options contract(s) on the opposite side of the market 
representing either (A) the same number of units of the underlying 
stock or convertible security, or (B) the number of units of the 
underlying stock necessary to create a delta neutral position, but 
in no case in a ratio greater than eight-to-one (8.00), where the 
ratio represents the total number of units of the underlying stock 
or convertible security in the option leg to the total number of 
units of the underlying stock or convertible security in the stock 
leg. See Options 3, Section 14(a)(2).
    \71\ A Stock-Complex Order is an order for a Stock-Complex 
Strategy, which is the purchase or sale of a stated number of units 
of an underlying stock or a security convertible into the underlying 
stock (``convertible security'') coupled with the purchase or sale 
of a Complex Options Strategy on the opposite side of the market 
representing either (A) the same number of units of the underlying 
stock or convertible security, or (B) the number of units of the 
underlying stock necessary to create a delta neutral position, but 
in no case in a ratio greater than eight-to-one (8.00), where the 
ratio represents the total number of units of the underlying stock 
or convertible security in the option legs to the total number of 
units of the underlying stock or convertible security in the stock 
leg. See Options 3, Section 14(a)(3).
    \72\ The Exchange will initially permit a maximum of 10 legs.
    \73\ See Cboe Rule 5.70(b) for similar provisions except the 
Exchange is not proposing Asian-settled or Cliquet-settled FLEX 
Index Options, as currently specified in Cboe Rule 5.70(b)(3).
    \74\ See Securities Exchange Act Release No. 98450(September 20, 
2023), 88 FR 66111 (September 26, 2023) (SR-ISE-2023-08) (Order 
Granting Approval of a Proposed Rule Change, as Modified by 
Amendment No. 1, To Make Permanent Certain P.M.-Settled Pilots).
    \75\ See Supplementary Material .07(a) to Options 4A, Section 
12.
    \76\ See Supplementary Material .07(b) to Options 4A, Section

    \77\ See Options 4A, Section 12(a)(5).
    \78\ See supra note 73.
---------------------------------------------------------------------------

    Pursuant to proposed Section 7(b), complex FLEX Orders will not 
have to adhere to the ratio requirements in Options 3, Sections 
14(a)(1)-(3). Options 3, Sections 14(a)(1)-(3) currently includes the 
complex ratio requirements for Complex Options Strategies, Stock-
Options Strategies, and Stock-Complex Strategies.\79\ The Exchange is 
not changing the complex ratio requirements for non-FLEX complex orders 
under this proposal. Instead, it is proposing to offer this feature 
only for complex FLEX Orders so that Members may submit complex FLEX 
Orders with any ratio.\80\ The Exchange notes that Cboe currently 
permits complex FLEX Orders to be submitted with any ratio.\81\
---------------------------------------------------------------------------

    \79\ See supra notes 69-71.
    \80\ For instance, the Exchange may permit Complex Options 
Strategies with a ratio on the options legs less than one-to-three 
(.333) or greater than three-to-one (3.00), and Stock-Option 
Strategies with a ratio greater than eight-to-one (8.00), where the 
ratio represents the total number of units of the underlying stock 
or convertible security in the option leg(s) to the total number of 
units of the underlying stock or convertible security in the stock 
leg.
    \81\ See Cboe US Options Complex Book Process, Section 2.1 
(Ratios) and Section 3 (Complex FLEX Order Functionality), available 
at <a href="https://cdn.cboe.com/resources/membership/US-Options-Complex-Book-Process.pdf">https://cdn.cboe.com/resources/membership/US-Options-Complex-Book-Process.pdf</a>. For its non-FLEX market, the Exchange will 
continue to require non-FLEX complex orders to adhere to the complex 
ratios in Options 3, Sections 14(a)(1)-(3), and therefore will not 
permit non-FLEX complex orders to be submitted in any ratio outside 
of those stipulated in Section 14.
---------------------------------------------------------------------------

I. Opening of FLEX Trading (Section 8)

    Proposed Section 8(a) will specify that there will be no Opening 
Process \82\ pursuant to Options 3, Section 8 in FLEX Options. Instead, 
as specified in proposed Section 8(b), Members may begin submitting 
FLEX Orders into an electronic FLEX Auction pursuant to proposed 
Section 11(b), a FLEX PIM pursuant to proposed Section 12, or a FLEX 
SOM pursuant to proposed Section 13 when the underlying security is 
open for trading.\83\ The Exchange will also make clear in proposed 
Section 8(b) that for FLEX Index Options, the term ``underlying 
security'' will have the same meaning as defined in Options 4A, Section 
2(q).\84\
---------------------------------------------------------------------------

    \82\ As described in Options 3, Section 8(c)(i), ISE's ``Opening 
Process'' for an option series is conducted pursuant to Options 3, 
Section 8 paragraphs (f)-(j), on or after 9:30 a.m. Eastern Time if 
the Away Best Bid or Offer, if any, is not crossed and the System 
has received, within two minutes of the opening trade or quote on 
the market for the underlying security, a Valid Width Quote. The 
System will accept a Primary Market Maker's Valid Width Quote or the 
Valid Width Quote of at least one Competitive Market Maker. The term 
``Away Best Bid or Offer'' or ``ABBO'' means the displayed National 
Best Bid or Offer not including the Exchange's Best Bid or Offer. 
See Options 1, Section 1(a)(4).
    \83\ See proposed Options 3A, Section 8(a) and (b), which is 
based on Cboe Rule 5.71 except with respect to open outcry trading 
and trading sessions outside of regular trading hours.
    \84\ Options 4A, Section 2(q) states that the term ``underlying 
security'' or ``underlying securities'' with respect to an index 
options contract means any of the securities that are the basis for 
the calculation of the index.
---------------------------------------------------------------------------

    Because market participants incorporate transaction prices of 
underlying securities or the values of underlying indexes when pricing 
options (including FLEX Options), the Exchange believes that it will 
benefit investors for FLEX Options trading to not be available until 
that information has begun to be disseminated in the market (i.e., when 
the security opens for trading).
    Additionally, the Exchange's Opening Process is used to open or 
reopen a series of options on ISE at a single opening price.\85\ There 
is a period of time before an options series opens during which orders 
placed on the Exchange's order book do not generate trade executions 
but may participate in the Opening Process.\86\ As noted above, FLEX 
Options will not be placed on the Exchange's simple and complex order 
books and therefore will not have an Opening Process.\87\ FLEX Options 
are created with terms unique to individual investment objectives. As 
such, each investor may require FLEX Options with slightly different 
terms than those already created. These individually defined FLEX 
Options are customized for each investor, so the Opening Process may 
not be useful for investors who may create their own FLEX Options 
because the Opening Process is designed, in part, to determine a single 
opening, or reopening, price based on orders and quotes from multiple 
Members. With the bespoke nature of FLEX Options, there is not the 
opportunity, nor the need, to bring together multiple orders and quotes 
as part of an Opening Process.
---------------------------------------------------------------------------

    \85\ See Options 3, Section 8(h) and (j).
    \86\ See Options 3, Section 8(c).
    \87\ See proposed Options 3A, Section 10(a). Instead, Members 
will be required to submit FLEX Orders into an electronic FLEX 
Auction, FLEX PIM, or FLEX SOM. See proposed Options 3A, Section 
11(a).
---------------------------------------------------------------------------

J. Trading Halts (Section 9)

    Proposed Section 9 will provide that the Exchange may halt trading 
in a FLEX Option class pursuant to Options 3, Section 9, and always 
halts trading in a FLEX Option class when trading in a non-FLEX Options 
class with the same underlying equity security or index is halted on 
the Exchange. The System will not accept a FLEX Order for a FLEX Option 
series while trading in a FLEX Option class is halted.\88\
---------------------------------------------------------------------------

    \88\ See Cboe Rule 4.21(a)(3) for materially identical 
provisions.
---------------------------------------------------------------------------

K. Exchange Order Books (Section 10)

    Proposed Section 10 will provide that the Exchange's simple and 
complex order books will not be available for transactions in FLEX 
Options. Accordingly, FLEX Options may only be traded on the Exchange 
by submitting FLEX Orders into a FLEX Electronic Auction pursuant to 
proposed Options 11(b), FLEX PIM pursuant to proposed Options 12, and 
FLEX SOM pursuant to proposed Options 13, each as discussed further 
below. The Exchange notes that its proposal is in line with other 
options exchanges' FLEX rules that do not contemplate the interaction 
of their respective order books with FLEX transactions.\89\
---------------------------------------------------------------------------

    \89\ See e.g., NYSE Arca Rule 5.30-O(c). See also Securities 
Exchange Act Release No. 87235 (October 4, 2019), 84 FR 54671 
(October 10, 2019) (SR-CBOE-2019-084) (among other changes, 
eliminating the availability of an electronic book for FLEX 
Options).
---------------------------------------------------------------------------

L. FLEX Options Trading (Section 11)

    Proposed Section 11 will describe the procedures for FLEX trading 
on the Exchange. Specifically, a FLEX Option series will only be 
eligible for trading if a Member submits a FLEX Order for that series 
into an electronic FLEX Auction pursuant to proposed paragraph (b) of 
Options 11, or submits the FLEX Order to a FLEX PIM or FLEX SOM Auction 
pursuant to proposed Section 12 or Section 13, respectively.\90\
---------------------------------------------------------------------------

    \90\ See proposed Options 3A, Section 11(a), which is based on 
Cboe Rule 5.72(b) except the Exchange is not proposing an open 
outcry FLEX Auction.
---------------------------------------------------------------------------

    Proposed Section 11(a)(1) and (2) will specify the requirements for 
both simple and complex FLEX Orders.
    <bullet> For a simple FLEX Order, a FLEX Order for a FLEX Option 
series submitted to the System must include all terms for a FLEX Option 
series set forth in proposed Section 3 as described

[[Page 94993]]

above, size, side of the market, and a bid or offer price.\91\ The 
Exchange also proposes that the System will not accept a FLEX Order 
with identical terms as a non-FLEX Option series that is already listed 
for trading to signify that this requirement is System-enforced.
---------------------------------------------------------------------------

    \91\ See Cboe Rule 5.72(b)(1) for similar provisions. The 
Exchange does not have an analogous rule as Cboe Rule 5.7, which 
specifies the different trading sessions during which the system is 
available to receive FLEX orders, and thus has not incorporated the 
applicable language. As noted above, the Exchange will accept FLEX 
Orders entered into an electronic FLEX Auction, FLEX PIM or FLEX SOM 
when the underlying security is open for trading. See proposed 
Options 3A, Section 8.
---------------------------------------------------------------------------

    <bullet> For a complex FLEX Order, a FLEX Order for a FLEX Option 
complex strategy submitted to the System must satisfy the criteria for 
a complex FLEX Order set forth in proposed Section 7(a) as described 
above, and include size, side of the market, and a net debit or credit 
price. Additionally, each leg of the FLEX Option complex strategy must 
include all terms for a FLEX Option series set forth in proposed 
Section 3.\92\ Similar to simple FLEX Orders, the Exchange proposes to 
System enforce the stipulation that it will not accept a FLEX Option 
complex strategy if a leg in the order has identical terms as a non-
FLEX Option series that is already listed for trading.\93\ The Exchange 
also proposes to add similar language as BOX to describe what would 
happen if there is a complex FLEX Order and subsequently, a non-FLEX 
Option series is introduced for the component leg(s). Specifically, 
proposed Section 11(a)(2)(A)(i) and (ii) will provide that if a non-
FLEX Option series is added intra-day for a component leg(s) of a 
complex FLEX Order, the holder or writer of a FLEX Option position in 
the component leg(s) resulting from such complex FLEX Order would be 
permitted to close its position(s) under the FLEX trading procedures 
against another closing only FLEX Option position for the balance of 
the trading day on which the non-FLEX Option series is added. If a non-
FLEX Option series is added for a component leg(s) of a complex FLEX 
Order on a trading day after the complex FLEX Order position is 
established, the holder or writer of a FLEX Option position in the 
component leg(s) resulting from such complex FLEX Order would be 
required to execute separate FLEX Option and non-FLEX Option 
transactions to close its position(s), such that FLEX Option component 
leg(s) would trade under the FLEX trading procedures and non-FLEX 
Option component leg(s) would trade subject to the non-FLEX trading 
procedures and rules.\94\ Additionally, a complex FLEX Order submitted 
into the System for an electronic FLEX Auction pursuant to proposed 
Section 11(b), a FLEX PIM pursuant to Section 12, or a FLEX SOM 
pursuant to Section 13 must include a bid or offer price for each leg, 
which leg prices when combined must equal the net price of the complex 
FLEX Order.\95\
---------------------------------------------------------------------------

    \92\ See Cboe Rule 5.72(b)(2) for similar provisions. As noted 
above for simple FLEX Orders, the Exchange does not have an 
analogous rule as Cboe Rule 5.7, and thus has not incorporated the 
applicable language. See supra note 91.
    \93\ See proposed Options 3A, Section 11(a)(2)(A).
    \94\ See proposed Options 3A, Section 11(a)(2)(A)(i) and (ii), 
which is materially identical to BOX Rule 7605(d).
    \95\ See proposed Options 3A, Section 11(a)(2)(B), which is 
based on Cboe Rule 5.72(b)(2)(A) except the Exchange will also add 
references to FLEX PIM and FLEX SOM for accuracy and completeness. 
The Exchange will also clarify in its proposed rule that the leg 
prices when combined must equal the net price of the complex FLEX 
Order (additions emphasized). Cboe's rule currently states that the 
leg prices ``must add together to equal'' the net price. However, 
the Exchange notes that sell legs of a complex order are subtracted, 
and therefore proposes the language in Options 3A, Section 
11(a)(2)(B) (instead of copying Cboe Rule 5.72(b)(2)(A)) for greater 
accuracy.
---------------------------------------------------------------------------

    Proposed Section 11(b) will describe the electronic FLEX Auction. 
The proposed FLEX Auction will be substantially similar to Cboe's 
electronic FLEX Auction set forth in Cboe Rule 5.72(c), except for 
certain intended differences as further described below.\96\ 
Specifically, a Member may electronically submit a FLEX Order (simple 
or complex) into an electronic FLEX Auction for execution pursuant to 
this paragraph (b). Pursuant to proposed subparagraph (b)(1), a FLEX 
Auction may be initiated if all of the below conditions in proposed 
subparagraph (b)(1)(A)-(G) are met; otherwise, the System rejects or 
cancels a FLEX Order that does not meet the conditions in this 
subparagraph (b)(1).\97\
---------------------------------------------------------------------------

    \96\ See also Securities Exchange Act Release No. 87235 (October 
4, 2019), 84 FR 54671 (SR-CBOE-2019-084) (October 10, 2019) 
(adopting an electronic FLEX Auction on Cboe, among other changes).
    \97\ Proposed paragraph (b) is based on Cboe Rule 5.72(c). The 
proposed eligibility requirements for the FLEX Auction in 
subparagraph (b)(1) are similar to Cboe Rule 5.72(c)(1), except as 
noted below.
---------------------------------------------------------------------------

    <bullet> Class: The FLEX Order is in a class of options the 
Exchange is authorized to list for trading on the Exchange.
    <bullet> Size: There is no minimum size for FLEX Orders.
    <bullet> Terms: A simple or complex FLEX Order must comply with 
proposed Section 11(a).
    <bullet> Price: The bid or offer price, or the net debit or credit 
price, as applicable, of the FLEX Order is the ``auction price.''
    <bullet> Time: A FLEX Order may only be submitted for electronic 
execution in a FLEX Auction after FLEX trading has opened pursuant to 
proposed Section 8.
    <bullet> Exposure Interval: The submitting Member must designate 
the length of the ``exposure interval,'' which must be between three 
seconds and five minutes.\98\ If the designated time exceeds the market 
close, then the FLEX Auction will end at the market close with an 
execution, if an execution is permitted pursuant to proposed Section 
11(b).\99\
---------------------------------------------------------------------------

    \98\ There will be no default setting to the FLEX Auction 
exposure interval. As such, Members will be required to specify the 
exposure interval; otherwise, their FLEX Order will be rejected by 
the System.
    \99\ Cboe Rule 5.72(c)(1)(F) does not specify whether an 
execution would occur (if permitted) when the designated time 
exceeds the market close, and only expressly prohibits the 
designated time from going beyond the market close. While the 
Exchange's rules are silent in this regard, the Exchange notes that 
its proposal will follow current non-FLEX auction behavior, 
including current PIM and SOM behavior. In doing so, the Exchange's 
proposal will promote executions in electronic FLEX Auctions 
(instead of cancelling the FLEX Order) and also prevent executions 
that occur after the market close.
---------------------------------------------------------------------------

    <bullet> Minimum Increment: The price of a simple FLEX Order must 
be in an increment the Exchange determines on a class basis (which may 
not be smaller than the amounts set forth in proposed Section 5 (i.e., 
$0.01)). If the FLEX Order is a complex order, the price must be a net 
price for the complex strategy.\100\ The foregoing rule proposal will 
be substantially similar to the minimum increment requirements in Cboe 
Rules 5.73(a)(5) and 5.74(a)(5). While the Exchange will align to 
Cboe's minimum increment requirements (i.e., $0.01) for the individual 
options legs of a complex FLEX Order entered into a FLEX Auction, the 
Exchange also proposes to align the minimum increment requirements for 
stock-tied FLEX complex strategies with the existing requirements for 
stock-tied non-FLEX complex strategies as set forth in Options 3, 
Section 14(c)(1). As such, proposed Options 3A, Section 11(b)(1)(G) 
will further provide that the prices of Complex Options Strategies (as 
defined in Options 3, Section 14) may

[[Page 94994]]

be expressed in one cent ($0.01) increments, and the options leg of 
Complex Options Strategies may be executed in no smaller than one cent 
($0.01) increments, regardless of the minimum increments otherwise 
applicable to the individual options legs of the order. Prices of 
Stock-Option Strategies or Stock-Complex Strategies (each as defined in 
Options 3, Section 14) may be expressed in any decimal price determined 
by the Exchange,\101\ and the stock leg of a Stock-Option Strategy or 
Stock-Complex Strategy may be executed in any decimal price permitted 
in the equity market. The options leg of a Stock-Option Strategy or 
Stock-Complex Strategy may be executed in no smaller than one cent 
($0.01) increments, regardless of the minimum increments otherwise 
applicable to the individual options legs of the order. Similar to 
stock-tied complex orders today, the Exchange believes that smaller 
minimum increments are appropriate for complex FLEX Orders that contain 
a stock component as the stock component can trade at finer decimal 
increments permitted by the equity market.
---------------------------------------------------------------------------

    \100\ See proposed subparagraph (G) of Section 11(b)(1). While 
Cboe's electronic FLEX Auction eligibility requirements in Rule 
5.72(c)(1) are silent on minimum increments, the eligibility 
requirements for Cboe's FLEX AIM and FLEX SAM in Cboe Rules 
5.73(a)(5) and 5.74(a)(5), respectively, address minimum increments. 
The Exchange believes it will be helpful to add a similar 
requirement for electronic FLEX Auctions for greater consistency and 
clarity. The Exchange also notes that unlike Cboe, it is not 
proposing to allow exercise prices to be expressed as percentages, 
and will therefore not incorporate the applicable provisions. As 
discussed above, the Exchange is also incorporating within proposed 
subparagraph (G) the minimum increment provisions for non-FLEX 
complex orders that are stock-tied from Options 3, Section 14(c)(1).
    \101\ The minimum increment for individual options leg of a FLEX 
Order may not be smaller than $0.01, as required under proposed 
Options 3A, Section 5. However, when a stock leg is included in a 
complex strategy (i.e., Stock-Option Strategy or Stock-Complex 
Strategy) for the FLEX Option, then the price for FLEX Stock-Option 
Strategies and FLEX Stock-Complex Strategies can be expressed to 
four decimal places in order to trade at finer decimal increments 
permitted by the equity market. However, the options leg will not be 
permitted to execute in increments smaller than one cent ($0.01). 
This is identical to how a non-FLEX Stock-Option Strategy and a non-
FLEX Stock-Complex Strategy can be priced today. See Options 3, 
Section 14(c)(1) for identical provisions. See also Securities 
Exchange Act Release No. 84373 (October 5, 2018), 83 FR 51730 at 
51732 (October 12, 2018) (SR-ISE-2018-56).
---------------------------------------------------------------------------

    Proposed subparagraph (b)(2) of Options 11 will describe the FLEX 
Auction process, and will provide that upon receipt of a FLEX Order 
that meets the conditions in subparagraph (a) as described above, the 
FLEX Auction commences. Proposed subparagraph (b)(2)(A) will describe 
the contents of the FLEX Auction message, and will provide that the 
System initiates a FLEX Auction by sending a FLEX Auction notification 
message to Members detailing the FLEX Option series or complex strategy 
(as applicable), side, size, auction ID,\102\ capacity, and exposure 
interval. Similar to all other auction notifications, FLEX Auction 
notification messages are not disseminated to OPRA.\103\ Like Cboe, the 
FLEX Auction message will not include the price of the auctioned FLEX 
Order. The Exchange believes not including the auction price in the 
notification message will encourage Members to respond with the best 
prices at which they are willing to trade against the auctioned FLEX 
Order. If the message included the price, Members may only respond to 
trade at that price; without the price, Members may respond at better 
prices, which may result in price improvement opportunities for the 
auctioned FLEX Order.
---------------------------------------------------------------------------

    \102\ As discussed below, this information on the proposed 
auction message will permit responses to only execute at the 
conclusion of the auction into which the responses were submitted.
    \103\ See Cboe Rule 5.72(c)(2)(A) for similar provisions, except 
with respect to the exposure interval and Attributable designation. 
The Exchange will simply disseminate the duration of the exposure 
interval, instead of calculating and disseminating what time the 
auction will conclude like Cboe. In addition, the Exchange is not 
proposing to offer an Attributable designation for FLEX Orders like 
Cboe does today.
---------------------------------------------------------------------------

    Proposed subparagraph (b)(2)(B) will provide that one or more FLEX 
Auctions in the same FLEX Option series or complex strategy (as 
applicable) may occur at the same time. To the extent there is more 
than one FLEX Auction in a FLEX Option series or complex strategy (as 
applicable) underway at the same time, the FLEX Auctions conclude 
sequentially based on the times at which each FLEX Auction's exposure 
interval concludes. At the time each FLEX Auction concludes, the System 
allocates the FLEX Order pursuant to proposed subparagraph (3) and 
takes into account all FLEX responses submitted during the exposure 
interval.\104\ Generally, if a Member attempts to initiate an 
electronic FLEX Auction in a FLEX Option series while another auction 
in that series is ongoing, the Exchange believes it will provide that 
second FLEX Order with an opportunity for execution in a timely manner 
by initiating another FLEX Auction, rather than having the Member wait 
for the first auction to conclude. The second Member may not be able to 
submit a response to trade in the ongoing FLEX Auction, because the 
terms may not be consistent with that Member's order (for example, 
there may not be sufficient size, and the Member may only receive a 
share of the auctioned order depending on other responses). Therefore, 
the Exchange believes providing this proposed functionality may 
encourage Members to use electronic FLEX Auctions to execute their FLEX 
Orders.
---------------------------------------------------------------------------

    \104\ See Cboe Rule 5.72(c)(2)(B) for materially identical 
provisions.
---------------------------------------------------------------------------

    Proposed subparagraph (b)(2)(C) will provide that the submitting 
Member may cancel a FLEX Auction prior to the end of the exposure 
interval.\105\ Proposed subparagraph (b)(2)(D) will specify the 
conditions for submitting responses to a FLEX Auction. Any Member 
(including the submitting Member) may submit responses to a FLEX 
Auction that are properly marked specifying the FLEX Option series or 
complex strategy (as applicable), bid or offer price or net price 
(respectively), size, side of the market, and the auction ID for the 
FLEX Auction to which the Member is submitting the response. A FLEX 
response may only participate in the FLEX Auction with the auction ID 
specified in the response, which is why the auction notification 
message described above will include an auction ID and responses must 
identify the applicable auction ID.\106\ If there are concurrent FLEX 
Auctions occurring, a Member may submit responses to all ongoing 
auctions, and thus concurrent auctions will not hinder a Member's 
ability to participate in any FLEX Auction.
---------------------------------------------------------------------------

    \105\ See Cboe Rule 5.72(c)(2)(C) for materially identical 
provisions. The Exchange notes that submitting Members may cancel 
but not modify a FLEX Auction prior to the end of the exposure 
interval.
    \106\ See Cboe Rule 5.72(c)(2)(D) for materially identical 
provisions.
---------------------------------------------------------------------------

    A Member using the same badge/ \107\ mnemonic \108\ may only submit 
a single FLEX response per auction ID to a FLEX Auction.\109\ If an 
additional FLEX response is submitted for the same auction ID from the 
same badge/mnemonic, then that FLEX response will automatically replace 
the previous FLEX response.\110\ The System caps the size of a FLEX 
response for the same badge/mnemonic at the size of the FLEX Order 
(i.e., the System ignores the size in excess of the size of the FLEX 
Order when processing the FLEX Auction).\111\

[[Page 94995]]

Given that the Exchange is proposing below to apply a pro-rata 
allocation methodology to executions at the conclusion of the FLEX 
Auction, this provision is intended to prevent a Member from submitting 
a response with an extremely large size into the electronic FLEX 
Auction in order to obtain a larger pro-rata share of the FLEX Order.
---------------------------------------------------------------------------

    \107\ A ``badge'' shall mean an account number, which may 
contain letters and/or numbers, assigned to Market Makers. A Market 
Maker account may be associated with multiple badges. See Options 1, 
Section 1(a)(5).
    \108\ A ``mnemonic'' shall mean an acronym comprised of letters 
and/or numbers assigned to Electronic Access Members. An Electronic 
Access Member account may be associated with multiple mnemonics. See 
Options 1, Section 1(a)(23).
    \109\ A badge and mnemonic are essentially Member identifiers. 
Every order that comes into the System is tied to a badge or 
mnemonic.
    \110\ In other words, the Member does not have to cancel the 
previous FLEX response before submitting an additional one as the 
previous response is automatically replaced. See proposed Options 
3A, Section 11(b)(2)(D)(i), which is based on Cboe Rule 
5.72(c)(2)(D)(i) except the Exchange will not allow Members to 
submit multiple FLEX responses using the same badge/mnemonic, and 
will not aggregate all of the Member's FLEX responses. While not 
specified in the Exchange's current rules, this is consistent with 
current auction behavior, including current PIM and SOM behavior.
    \111\ See proposed Options 3A, Section 11(b)(2)(D)(ii), which is 
based on Cboe Rule 5.72(c)(2)(D)(ii) except the Exchange will not 
aggregate all of the Member's FLEX responses. See supra note 110.
---------------------------------------------------------------------------

    Further, FLEX responses must be on the opposite side of the market 
as the FLEX Order. The System rejects a FLEX response on the same side 
of the market as the FLEX Order.\112\ FLEX responses are not visible to 
Members or disseminated to OPRA.\113\ This is consistent with how Cboe 
treats FLEX responses pursuant to Cboe Rule 5.72(c)(2)(D)(iv). The 
proposed rule change is also consistent with the Exchange's existing 
auctions, in which responses are not visible to the market.\114\ 
Responses to electronic auctions are not firm prior to the conclusion 
of the auction, at which time their price and size are firm. For the 
same reason as the Exchange is proposing not to disseminate the auction 
price on the auction notification message as discussed above, the 
Exchange believes it will encourage Members to submit responses at 
their best possible price if they do not know the prices at which other 
Members are willing to trade.\115\
---------------------------------------------------------------------------

    \112\ See proposed Options 3A, Section 11(b)(2)(D)(iii), which 
is based on Cboe Rule 5.72(c)(2)(D)(iii).
    \113\ See proposed Options 3A, Section 11(b)(2)(D)(iv), which is 
based on Cboe Rule 5.72(c)(2)(D)(iv).
    \114\ See Supplementary Material .02 to Options 3, Section 11; 
and Options 3, Section 13(c)(4).
    \115\ For example, if during a FLEX Auction of a buy FLEX Order, 
a Member submitted a response to sell at $1.05, if another Member 
saw that response, it may merely respond to sell at $1.05, or maybe 
$1.04, even though it may ultimately be willing to sell at $1.03. 
Without seeing the other responses, the second Member may instead 
submit a response to sell at $1.03, which could result in price 
improvement for the auctioned order.
---------------------------------------------------------------------------

    A Member may modify or cancel it FLEX Responses during the exposure 
interval.\116\ The minimum price increment for FLEX responses is the 
same as the one the Exchange determines for a class pursuant to 
proposed subparagraph (b)(1)(G) above. A response to a FLEX Auction of 
a complex order must have a net price. The System rejects a FLEX 
response that is not in the applicable minimum increment.\117\
---------------------------------------------------------------------------

    \116\ See proposed Options 3A, Section 11(b)(2)(D)(v), which is 
based on Cboe Rule 5.72(c)(2)(D)(v).
    \117\ See proposed Options 3A, Section 11(b)(2)(D)(vi). While 
Cboe's electronic FLEX Auction response requirements in Rule 
5.72(c)(2)(D) are silent on minimum increments, the response 
requirements for Cboe's FLEX AIM and FLEX SAM in Cboe Rules 
5.73(c)(5)(A) and 5.74(c)(5)(A), respectively, have similar 
provisions. The Exchange believes it will be helpful to add a 
similar requirement for electronic FLEX Auction responses for 
greater consistency and clarity. The Exchange also notes that unlike 
Cboe, it is not proposing to allow percentage formats for exercise 
prices of FLEX Options, and will therefore not incorporate the 
applicable provisions.
---------------------------------------------------------------------------

    Pursuant to proposed subparagraph (b)(3) of Section 11, the FLEX 
Auction concludes at the end of the exposure interval, unless the 
Exchange halts trading in the affected underlying or the submitting 
Member cancels the FLEX Auction before the end of the exposure 
interval, in which case the FLEX Auction concludes without 
execution.\118\ At the conclusion of the FLEX Auction:
---------------------------------------------------------------------------

    \118\ See Cboe Rule 5.72(c)(3) for similar provisions, except 
the Exchange is making minor modifications to replace ``affected 
series'' with ``affected underlying'' and to specify that the 
submitting Member has to cancel the FLEX Auction before the end of 
the exposure period. The foregoing changes are merely clarifications 
to better articulate the functionality.
---------------------------------------------------------------------------

    <bullet> Pursuant to proposed subparagraph (b)(3)(A), the System 
executes the FLEX Order against the FLEX responses at the best 
price(s), to the price at which the balance of the FLEX Order or the 
FLEX responses can be fully executed (the ``final auction price''). For 
purposes of ranking FLEX responses when determining how to allocate a 
FLEX Order, the term ``price'' refers to the dollar and decimal amount 
of the response bid or offer.\119\
---------------------------------------------------------------------------

    \119\ See Cboe Rule 5.72(c)(3)(A) for similar provisions, except 
the Exchange is not proposing to allow percentage values of the 
response bid or offer.
---------------------------------------------------------------------------

    <bullet> Pursuant to proposed subparagraph (b)(3)(A)(i), if there 
are multiple FLEX responses at the same price level, then the contracts 
in those FLEX responses are allocated proportionally according to Size 
Pro-Rata Priority \120\ with Priority Customer \121\ overlay \122\ (as 
described in Options 3, Section 10(c)(1)(A)). The Exchange notes that 
this is similar to Cboe Rule 5.72(c)(3)(A)(i), except Cboe applies no 
overlays to its size pro-rata allocation methodology whereas the 
Exchange will apply an overlay for Priority Customers on top of its 
standard size pro-rata allocation methodology. This is consistent with 
the Exchange's standard allocation methodology in its SOM and PIM for 
non-FLEX Options where the Priority Customer gets priority treatment 
over non-Priority Customers.\123\
---------------------------------------------------------------------------

    \120\ Size Pro-Rata Priority shall mean that if there are two or 
more resting orders or quotes at the same price, the System 
allocates contracts from an incoming order or quote to resting 
orders and quotes beginning with the resting order or quote 
displaying the largest size proportionally according to displayed 
size, based on the total number of contracts displayed at that 
price. See Options 3, Section 10(c).
    \121\ The term ``Priority Customer'' means a person or entity 
that (i) is not a broker or dealer in securities, and (ii) does not 
place more than 390 orders in listed options per day on average 
during a calendar month for its own beneficial account(s). See 
Options 1, Section 1(a)(37).
    \122\ Priority Customer overlay mean that the highest bid and 
lowest offer shall have priority except that Priority Customer 
orders shall have priority over non-Priority Customer interest at 
the same price in the same options series. If there are two or more 
Priority Customer orders for the same options series at the same 
price, priority shall be afforded to such Priority Customer orders 
in the sequence in which they are received by the System. See 
Options 10, Section 10(c)(1)(A).
    \123\ See, e.g., Options 3, Section 11(d)(3)(C) (SOM allocation 
methodology) and Options 3, Section 13(d) (PIM allocation 
methodology).
---------------------------------------------------------------------------

    <bullet> Pursuant to proposed subparagraph (b)(3)(A)(ii), the 
executable quantity is allocated to the nearest whole number, with 
fractions rounded up for the FLEX response with the higher quantity. 
Further, proposed subparagraph (b)(3)(A)(iii) will provide that if an 
allocation would result in less than one contract, then one contract 
will be allocated. The Exchange is not adopting the rounding and 
allocation language in Cboe Rule 5.72(c)(3)(A)(ii) and (iii), but is 
rather adopting language that is consistent with its current rounding 
and allocation methodology as the Exchange does not allocate fractional 
contracts and instead rounds up to the nearest whole number.\124\
---------------------------------------------------------------------------

    \124\ See Options 3, Section 10(c), Supplementary Material .09 
to Options 3, Section 11, and Supplementary Material .10 to Options 
3, Section 13.
---------------------------------------------------------------------------

    Pursuant to proposed subparagraph (b)(3)(B), the System cancels an 
unexecuted FLEX Order (or unexecuted portion).\125\ Further, proposed 
subparagraph (b)(3)(C) will provide that the System cancels any 
unexecuted responses (or unexecuted portions).\126\
---------------------------------------------------------------------------

    \125\ See Cboe Rule 5.72(c)(3)(B) for materially identical 
provisions.
    \126\ See Cboe Rule 5.72(c)(3)(C) for materially identical 
provisions.
---------------------------------------------------------------------------

M. FLEX PIM (Section 12)

    The Exchange proposes to establish PIM auction functionality for 
FLEX Options in Options 3A, Section 12. The proposed FLEX PIM auction 
will be substantially similar to Cboe's FLEX AIM in Cboe Rule 5.73, 
except for certain intended differences as further described below. 
Pursuant to proposed Section 12, a Member (the ``Initiating Member'') 
may electronically submit for execution an order (which may be a simple 
or complex order) it represents as agent (``Agency Order'') against

[[Page 94996]]

principal interest or a solicited order(s) (except, if the Agency Order 
is a simple order, for an order for the account of any FLEX Market 
Maker with an appointment in the applicable FLEX Option class on the 
Exchange) (an ``Initiating Order''), provided it submits the Agency 
Order for electronic execution into a FLEX PIM auction pursuant to this 
Rule.\127\
---------------------------------------------------------------------------

    \127\ See Cboe Rule 5.73 for similar provisions, except the 
Exchange will not incorporate the reference to FLEX SPX as this is a 
Cboe-specific product.
---------------------------------------------------------------------------

    Proposed Section 12(a)(1)--(5) will set forth the FLEX PIM auction 
eligibility requirements. Specifically, the Initiating Member may 
initiate a FLEX PIM auction if all of the following conditions are met:
    <bullet> Class. An Agency Order must in a FLEX Option class the 
Exchange designates as eligible for FLEX PIM auctions.
    <bullet> FLEX Option Series. The Agency Order and Initiating Order 
must each be a FLEX Order that complies with proposed Section 11(a) in 
a permissible FLEX Option series that complies with proposed Section 3 
above. For a complex FLEX Order, each leg must be in a permissible FLEX 
option series that complies with proposed Section 3 above.\128\
---------------------------------------------------------------------------

    \128\ See Cboe Rule 5.73(a)(2) for similar provisions, except 
the Exchange will add a similar stipulation for each leg of a 
complex FLEX Order for clarity.
---------------------------------------------------------------------------

    <bullet> Marking. The Initiating Member must mark an Agency Order 
for FLEX PIM auction processing.
    <bullet> Size. There will be no minimum size for Agency Orders. The 
Initiating Order must be for the same size as the Agency Order.
    <bullet> Minimum Increment. The price of the Agency Order and 
Initiating Order for simple FLEX Orders must be in an increment the 
Exchange determines on a class basis (which may not be smaller than the 
amounts set forth in Section 5 above). If the Agency Order and 
Initiating Order are complex orders, the price must be a net price for 
the complex strategy.\129\ While the Exchange will align to Cboe's 
minimum increment requirements (i.e., $0.01) for the individual options 
legs of a complex FLEX Order entered into a FLEX PIM, the Exchange also 
proposes to align the minimum increment requirements for stock-tied 
FLEX complex strategies with the existing requirements for stock-tied 
non-FLEX complex strategies as set forth in Options 3, Section 
14(c)(1). As such, proposed Options 3A, Section 12(a)(5) will further 
provide that the prices of Complex Options Strategies (as defined in 
Options 3, Section 14) may be expressed in one cent ($0.01) increments, 
and the options leg of Complex Options Strategies may be executed in no 
smaller than one cent ($0.01) increments, regardless of the minimum 
increments otherwise applicable to the individual options legs of the 
order. Prices of Stock-Option Strategies or Stock-Complex Strategies 
(each as defined in Options 3, Section 14) may be expressed in any 
decimal price determined by the Exchange,\130\ and the stock leg of a 
Stock-Option Strategy or Stock-Complex Strategy may be executed in any 
decimal price permitted in the equity market. The options leg of a 
Stock-Option Strategy or Stock-Complex Strategy may be executed in no 
smaller than one cent ($0.01) increments, regardless of the minimum 
increments otherwise applicable to the individual options legs of the 
order. Similar to stock-tied complex orders today, the Exchange 
believes that smaller minimum increments are appropriate for complex 
FLEX Orders that contain a stock component as the stock component can 
trade at finer decimal increments permitted by the equity market.
---------------------------------------------------------------------------

    \129\ The Exchange notes that unlike Cboe, it will not allow 
prices to be entered as a percentage value, and therefore will not 
incorporate the applicable language from Cboe Rule 5.73(a)(5) into 
proposed Section 12(a)(5). As discussed above, the Exchange will 
also add existing complex order minimum increment requirements in 
Options 3, Section 14(c)(1) to align the proposed FLEX functionality 
with non-FLEX functionality.
    \130\ The prices of the FLEX Stock-Option Strategies and FLEX 
Stock-Complex Strategies can be expressed to four decimal places, 
which is identical to how the stock portion of a non-FLEX Stock-
Option Strategy and a non-FLEX Stock-Complex Strategy can be priced 
today. However, the options leg will not be permitted to execute in 
increments smaller than one cent ($0.01). See supra note 101.
---------------------------------------------------------------------------

    <bullet> Time. An Initiating Member may only submit an Agency Order 
to a FLEX PIM auction after trading in FLEX Options is open pursuant to 
proposed Section 8.
    The System will reject or cancel both an Agency Order and 
Initiating Order submitted to a FLEX PIM auction that do not meet the 
conditions in proposed paragraph (a) as described above. The proposed 
FLEX PIM eligibility requirements in proposed Section 12(a) are 
substantially similar to Cboe's FLEX AIM eligibility requirements in 
Cboe Rule 5.73(a), except with respect to the language related to the 
percentage value, as noted above.
    Pursuant to proposed Section 12(b), the Initiating Order must stop 
the entire Agency Order at a specified price. If the Agency Order and 
Initiating Order are Complex Orders, the price must be a net price for 
the complex strategy.\131\ In particular, the Initiating Member must 
specify either of the below; otherwise, the System will reject or 
cancel both an Agency Order and Initiating Order submitted to a FLEX 
PIM auction that do not meet the conditions in this proposed paragraph 
(b).
---------------------------------------------------------------------------

    \131\ See Cboe Rule 5.73(b) for similar provisions, except the 
Exchange will not allow prices to be entered as a percentage value, 
and therefore will not incorporate the applicable language from 
Cboe's rule into proposed Section 12(b).
---------------------------------------------------------------------------

    <bullet> Pursuant to proposed subparagraph (b)(1), a single price 
at which it seeks to execute the Agency Order against the Initiating 
Order (a ``single-price submission''), including whether it elects to 
have less than its guaranteed allocation (as described in proposed 
Section 12(e)(4) below). This is similar to Cboe Rule 5.73(b)(1), 
except the Exchange is not proposing to allow Initiating Members to 
elect for the Initiating Order to have last priority to trade against 
the Agency Order, and will instead allow them to elect less than their 
guaranteed allocation.\132\ As further discussed below, the proposed 
guaranteed allocation process will be based on the guaranteed 
allocation process available in non-FLEX PIM auctions, and therefore 
the proposed rule change will provide further consistency across the 
Exchange's auction mechanism processes.\133\
---------------------------------------------------------------------------

    \132\ The Exchange will allow the Initiating Member to customize 
their guaranteed allocation percentage of the Initiating Order 
anywhere from 0% up to 50% of the Agency Order (if there is a 
response(s) from one other Member at the same price) or up to 40% of 
the Agency Order (if there are responses from two or more Members at 
the same price). For example, an Agency Order is entered into FLEX 
PIM for 100 contracts. If the Initiating Member only wants to have a 
guaranteed allocation of 10% on the Initiating Order that was 
entered with the Agency Order, the Initiating Member can stipulate 
10% on the Initiating Order. If there are 4 FLEX PIM responses for a 
total of 200 contracts at the end of the auction, then the 
Initiating Member will only get 10 contracts allocated on its 
Initiating Order (i.e., the guaranteed 10% of 100 contracts). Cboe's 
rule does not allow for the Initiating Member's guaranteed 
allocation percentages to be customized. See infra note 158 for 
further discussion on the 50%/40% allocation percentages.
    \133\ See infra note 158 for further discussion on the 50%/40% 
allocation percentages.
---------------------------------------------------------------------------

    <bullet> Pursuant to subparagraph (b)(2), an initial stop price and 
instruction to automatically match the price and size of all FLEX PIM 
responses (``auto-match'') at each price, up to a designated limit 
price, better than the price at which the balance of the Agency Order 
can be fully executed (the ``final auction price''). This is materially 
identical to Cboe Rule 5.73(b)(2).
    Proposed Section 12(c) will govern the FLEX PIM auction process. 
Specifically, upon receipt of an Agency

[[Page 94997]]

Order that meets the conditions in paragraphs (a) and (b) as described 
above, the FLEX PIM auction process commences. Proposed subparagraphs 
(c)(1)(A) and (B) will describe concurrent FLEX PIM auctions for simple 
Agency Orders and complex Agency Orders, respectively. One or more FLEX 
PIM auctions in the same FLEX Option series or same complex strategy 
(as applicable) may occur at the same time.\134\ To the extent there is 
more than one FLEX PIM auction in a FLEX Option series or complex 
strategy (as applicable) underway at the same time, the FLEX PIM 
auctions will conclude sequentially based on the times at which the 
FLEX PIM auction periods end. At the time each FLEX PIM auction 
concludes, the System allocates the Agency Order pursuant to proposed 
paragraph (e) as described below, and takes into account all FLEX PIM 
responses received during the FLEX PIM auction period. The concurrent 
FLEX PIM auction feature in proposed Section 12(c)(1)(A) and (B) is 
materially identical to Cboe Rule 5.73(c)(1)(A) and (B), and is also 
consistent with the concurrent auction feature proposed above for FLEX 
Auctions. Similar to FLEX Auctions as proposed above, if a Member 
attempts to initiate a FLEX PIM Auction in a FLEX Option series while 
another auction in that series in ongoing, the Exchange believes it 
will provide that second FLEX Order with an opportunity for execution 
in a timely manner by initiating another FLEX PIM Auction, rather than 
requiring the Member to wait for the first auction to conclude. The 
second Member may not be able to submit a response to trade in the 
ongoing FLEX PIM Auction because the terms may not be consistent with 
that Member's order (for example, there may not be sufficient size, and 
the Member may only receive a share of the auctioned order depending on 
other responses). Therefore, the Exchange believes that providing this 
functionality for FLEX PIM may provide additional opportunities for 
execution of FLEX Orders by encouraging Members to use FLEX PIM.
---------------------------------------------------------------------------

    \134\ Further, for complex Agency Orders, PIM auctions in 
different complex strategies may be ongoing at any given time, even 
if the complex strategies have overlapping components. A FLEX PIM 
auction in a complex strategy may be ongoing at the same time as a 
FLEX PIM auction in any component of the complex strategy. See 
proposed subparagraph (c)(1)(B)(i) of Options 3A, Section 12.
---------------------------------------------------------------------------

    Pursuant to proposed Section 12(c)(2), the System initiates the 
FLEX PIM auction process by sending a FLEX PIM auction notification 
message detailing the side, size, auction ID, the length of the FLEX 
PIM auction period, and FLEX Option series or complex strategy, as 
applicable, of the Agency Order to all Members that elect to receive 
FLEX PIM auction notification messages. The Exchange may also determine 
to include the stop price in FLEX PIM auction notification messages, 
which will apply to all FLEX PIM auctions. Similar to all other auction 
notifications, FLEX PIM auction notification messages will not be 
disseminated to OPRA.\135\
---------------------------------------------------------------------------

    \135\ See Cboe Rule 5.73(c)(2) for substantially similar 
provisions except the Exchange will not incorporate the reference to 
SPX as it does not list this symbol.
---------------------------------------------------------------------------

    Proposed Section 12(c)(3) will describe the ``FLEX PIM Auction 
period,'' and is based on Cboe Rule 5.73(c)(3). The FLEX PIM Auction 
period will be defined as a period of time that must be designated by 
the Initiating Member, which may be no less than three seconds and no 
more than five minutes. Similar to the exposure interval for electronic 
FLEX Auctions in Section 11(b) discussed above, the Initiating Member 
will be required to identify a length of time within the specified 
parameters for FLEX PIM as there will be no default for the FLEX PIM 
Auction period. Otherwise, their FLEX Order will be rejected by the 
System. Further, if the designated length of the FLEX PIM Auction 
period exceeds the market close, then the auction will end at the 
market close with an execution, if an execution is permitted by this 
Section 12. Cboe's rule does not specify whether an execution (if 
permitted) would occur if the designated length exceeds the market 
close. However, the Exchange's non-FLEX auctions currently allow 
executions (as permitted by their respective rules) to occur in such 
scenarios, so the Exchange proposes to be consistent with current 
System functionality in this regard.\136\ In doing so, the Exchange's 
proposal will promote executions in FLEX PIM (instead of cancelling the 
FLEX Order) and also prevent executions from occurring after the market 
close.
---------------------------------------------------------------------------

    \136\ While this behavior is not explicitly stated in the 
current Rules, the Exchange's proposal will be consistent with 
current non-FLEX auction behavior, including current PIM and SOM 
behavior.
---------------------------------------------------------------------------

    Proposed Section 12(c)(4) will provide that an Initiating Member 
may not modify or cancel an Agency Order or Initiating Order after 
submission to a FLEX PIM auction, except to improve the price of the 
Initiating Order. This will be similar to Cboe Rule 5.73(c)(4) except 
unlike Cboe, the Exchange will allow a limited exception by allowing 
Initiating Members to improve the price of their Initiating Orders. The 
Exchange notes that this will align to current non-FLEX PIM behavior, 
which allows entering Members to modify their Counter-Side Orders \137\ 
upon entry into the PIM by improving upon the initial price of the 
Counter-Side Order.\138\ Similar to allowing the initiating Member of a 
non-FLEX PIM to improve the initial price of its Counter-Side Order, 
the Exchange believes that it is appropriate to allow the Initiating 
Member of the FLEX PIM to improve the price of its Initiating Order 
(i.e., contra-side to the Agency Order) because it would also improve 
the stop price of the Agency Order that came in together with the 
Initiating Order.\139\
---------------------------------------------------------------------------

    \137\ Counter-Side Orders (i.e., contra-side to the Agency 
Order) for PIM are functionally equivalent to Initiating Orders 
(i.e., contra-side order to the Agency Order) for FLEX PIM. See 
Options 3, Section 13(b) for a description of Counter-Side Orders.
    \138\ See Options 3, Section 13(b)(5) (providing that the 
Crossing Transaction may not be canceled or modified, but the price 
of the Counter-Side Order may be improved during the exposure 
period).
    \139\ As proposed, the Initiating Member enters a paired FLEX 
Order into FLEX PIM consisting of an Agency Order and an Initiating 
Order (which is the contra-side of the Agency Order). This is 
identical to how standard non-FLEX PIM works today in that the 
Initiating Member enters a paired order into standard PIM consisting 
of an Agency Order and a Counter-Side Order (i.e., the PIM Agency 
Order's contra-side, and the functional equivalent to an Initiating 
Order on FLEX PIM).
---------------------------------------------------------------------------

    Proposed Section 12(c)(5) will govern the requirements for FLEX PIM 
responses. Specifically:
    <bullet> Any Member other than the Initiating Member (the System 
rejects a response with the same badge/mnemonic as the Initiating 
Order) may submit responses to a FLEX PIM auction that are properly 
marked specifying price, size, side, and the auction ID for the FLEX 
PIM auction to which the Member is submitting the response. A FLEX PIM 
response may only participate in the FLEX PIM auction with the auction 
ID specified in the response.\140\
---------------------------------------------------------------------------

    \140\ See proposed Options 3A, Section 12(c)(5), which is based 
on Cboe Rule 5.73(c)(5).
---------------------------------------------------------------------------

    <bullet> The minimum price increment for FLEX PIM responses is the 
same as the one the Exchange determines for a class pursuant to 
proposed Section 12(a)(5) above. A response to a FLEX PIM auction of a 
complex Agency Order must have a net price. The System will reject a 
FLEX PIM response that is not in the applicable minimum increment.\141\
---------------------------------------------------------------------------

    \141\ See proposed Options 3A, Section 12(c)(5)(A), which is 
based on Cboe Rule 5.73(c)(5)(A) except the Exchange will not allow 
prices to be expressed as a percentage value. Further, the Exchange 
will not incorporate the Cboe rule portions on Index Combo Orders as 
the Exchange does not offer this functionality.
---------------------------------------------------------------------------

    <bullet> A Member using the same badge/mnemonic may only submit a 
single

[[Page 94998]]

FLEX PIM response per auction ID for a given auction. If an additional 
FLEX PIM response is submitted for the same auction ID from the same 
badge/mnemonic, then that FLEX PIM response will automatically replace 
the previous FLEX PIM response.\142\
---------------------------------------------------------------------------

    \142\ See proposed Options 3A, Section 12(c)(5)(B), which will 
be different from Cboe Rule 5.73(c)(5)(B) because the Exchange will 
not allow Members to submit multiple FLEX PIM responses using the 
same badge/mnemonic, and will not aggregate all of the Member's FLEX 
PIM responses. While the rules are currently silent in this regard, 
this will align to current non-FLEX auction behavior, including PIM 
auction behavior.
---------------------------------------------------------------------------

    <bullet> The System will cap the size of a FLEX PIM response at the 
size of the Agency Order (i.e., the System will ignore size in excess 
of the size of the Agency Order when processing the FLEX PIM 
auction).\143\
---------------------------------------------------------------------------

    \143\ See proposed Options 3A, Section 12(c)(5)(C), which is 
based on Cboe Rule 5.73(c)(5)(C) except the Exchange will not allow 
Members to submit multiple FLEX PIM responses using the same badge/
mnemonic, and will not aggregate all of the Member's FLEX PIM 
responses. As noted above, this will align to current non-FLEX 
auction functionality, including PIM auction functionality in 
Options 3, Section 13.
---------------------------------------------------------------------------

    <bullet> FLEX PIM responses must be on the opposite side of the 
market as the Agency Order. The System rejects a FLEX PIM response on 
the same side of the market as the Agency Order.\144\
---------------------------------------------------------------------------

    \144\ See proposed Options 3A, Section 12(c)(5)(D), which is 
materially identical to Cboe Rule 5.73(c)(5)(D).
---------------------------------------------------------------------------

    <bullet> FLEX PIM responses will not be visible to PIM auction 
participants or disseminated to OPRA.\145\
---------------------------------------------------------------------------

    \145\ See proposed Options 3A, Section 12(c)(5)(E), which is 
materially identical to Cboe Rule 5.73(c)(5)(E).
---------------------------------------------------------------------------

    <bullet> A Member may modify or cancel its FLEX PIM responses 
during the FLEX PIM auction.\146\
---------------------------------------------------------------------------

    \146\ See proposed Options 3A, Section 12(c)(5)(F), which is 
materially identical to Cboe Rule 5.73(c)(5)(F).
---------------------------------------------------------------------------

    Pursuant to proposed Section 12(d), a FLEX PIM auction concludes at 
the earliest to occur of the following times: (1) the end of the FLEX 
PIM auction period; and (2) any time the Exchange halts trading in the 
affected underlying, provided, however, that in such instance the FLEX 
PIM auction concludes without execution.\147\
---------------------------------------------------------------------------

    \147\ See Cboe Rule 5.73(d) for similar provisions, except the 
Exchange will make a minor clarification that this rule applies when 
the Exchange halts trading in the affected underlying (and not 
series, which is what Cboe currently has in its rule).
---------------------------------------------------------------------------

    Proposed Section 12(e) will govern how executions will occur in 
FLEX PIM. In particular, at the end of the FLEX PIM auction, the System 
allocates the Initiating Order or FLEX PIM responses against the Agency 
Order at the best price(s), to the price at which the balance of the 
Agency Order can be fully executed (the ``final auction price''), as 
follows. For purposes of ranking the Initiating Order and FLEX PIM 
responses when determining how to allocate the Agency Order against the 
Initiating Order and those responses, the term ``price'' refers to the 
dollar and decimal amount of the order or response bid or offer.\148\ 
Proposed subparagraphs (e)(1)-(4) details the FLEX PIM allocation 
methodology for the following scenarios:
---------------------------------------------------------------------------

    \148\ See Cboe Rule 5.73(e) for similar provisions except the 
Exchange will not allow prices to be expressed as a percentage 
value.
---------------------------------------------------------------------------

    <bullet> No Price Improvement: If the FLEX PIM auction results in 
no price improvement, the System executes the Agency Order at the stop 
price in the following order:
    <bullet> Priority Customer responses (in time priority); \149\
---------------------------------------------------------------------------

    \149\ See proposed Section 12(e)(1)(A), which is materially 
identical to Cboe Rule 5.73(e)(1)(A).
---------------------------------------------------------------------------

    <bullet> The Initiating Order for the greater of (1) one contract 
or (2) up to 50% of the Agency Order if there is a response(s) from one 
other Member at the same price or 40% of the Agency Order if there are 
responses from two or more other Members at the same price (which 
percentages are based on the original size of the Agency Order).\150\ 
Unless there are remaining contracts after including all PIM responses, 
under no circumstances does the Initiating Member receive an allocation 
percentage at the final auction price of more than 50% of the initial 
Agency Order in the event there is a response(s) from one other Member 
or 40% of the initial Agency Order in the event there are responses 
from two or more other Members, except when rounding up. The Exchange 
is specifying two limited scenarios in this Rule where the Initiating 
Member may receive an allocation percentage greater than its guaranteed 
allocation percentage, which is either when there are remaining 
contracts after including all PIM responses or when rounding up.\151\ 
As an example of the first scenario, assume an Initiating Member 
submitted a FLEX Order for 20 contracts into FLEX PIM and there are 2 
PIM responses (one for 3 contracts and one for 4 contracts). After the 
7 PIM responses are allocated, the Initiating Member would then receive 
the remaining 13 contracts (which is more than their 40% allocation 
percentage) because there are remaining contracts after all PIM 
responses are included.
---------------------------------------------------------------------------

    \150\ See proposed Section 12(e)(1)(B)(ii), which is based on 
Cboe Rule 5.73(e)(1)(B)(ii) except the percentages will be based on 
the original size of the Agency Order, instead of the number of 
contracts remaining after execution against Priority Customer 
responses like Cboe. This will align to current PIM functionality. 
See Options 3, Section 13(d)(3). See infra note 158 for further 
discussion on the 50%/40% allocation percentages.
    \151\ See proposed Section 12(e)(1)(B), which is based on Cboe 
Rule 5.73(e)(1)(B) except with respect to the two limited scenarios 
discussed above. This behavior relating to the remaining contracts 
scenario and rounding up scenario will align to current PIM 
functionality. While the Exchange's rules are silent on the first 
scenario, the rounding up scenario is specified in Options 3, 
Section 13(d)(7).
---------------------------------------------------------------------------

    <bullet> All other FLEX PIM responses, allocated on a Size Pro-Rata 
basis (as defined in Options 3, Section 10(c)); \152\ and
---------------------------------------------------------------------------

    \152\ See proposed Section 12(e)(1)(C), which is materially 
identical to Cboe Rule 5.73(e)(1)(C). The Exchange notes that Size 
Pro-Rata (as defined in Options 3, Section 10(c)) is similar to pro-
rata as referenced in the Cboe rule (and as defined in Cboe Rule 
5.32(a)(1)(B)).
---------------------------------------------------------------------------

    <bullet> The Initiating Order to the extent there are any remaining 
contracts.\153\
---------------------------------------------------------------------------

    \153\ See proposed Section 12(e)(1)(D), which is materially 
identical to Cboe Rule 5.73(e)(1)(D).
---------------------------------------------------------------------------

    <bullet> Price Improvement With Single-Price Submission: If the 
FLEX PIM auction results in price improvement for the Agency Order and 
the Initiating Member selected a single-price submission, at each price 
better than the final auction price, the System executes the Agency 
Order in the following order:
    <bullet> Priority Customer responses (in time priority); \154\
---------------------------------------------------------------------------

    \154\ See proposed Section 12(e)(2)(A), which is materially 
identical to Cboe Rule 5.73(e)(2)(A).
---------------------------------------------------------------------------

    <bullet> Other FLEX PIM responses (in time priority) at prices 
better than the final auction price; and
    <bullet> All other FLEX PIM responses at the final auction price, 
allocated on a Size Pro-Rata basis (as defined in Options 3, Section 
10(c)).\155\
---------------------------------------------------------------------------

    \155\ See proposed Section 12(e)(2)(B), which is based on Cboe 
Rule 5.73(e)(2)(B), except the Exchange will specify that other FLEX 
PIM responses at prices better than the final auction price will be 
allocated in time priority and all other FLEX PIM responses at the 
final auction price will be allocated on a Size Pro-Rata Basis. 
While the current rules are silent in this regard, this behavior 
follows current System behavior for its PIM functionality.
---------------------------------------------------------------------------

    For example, assume a FLEX PIM Agency Order is sent for 100 
contracts with a price of $1.00 and the Initiating Member selected a 
single-price submission. There are two PIM responses for 5 contracts 
each at $0.98, two PIM responses for 20 contracts each at $0.99, and 
two PIM responses for 40 contracts each at $1.00. The PIM responses at 
$0.98 and $0.99 will be executed in their entirety. The PIM responses 
at $1.00 (final auction price) will be executed on a Size Pro-Rata 
basis. At the final auction price, the System executes any remaining 
contracts from the Agency Order at that

[[Page 94999]]

price in the order set forth in proposed Section 12(e)(1), as described 
above.\156\
---------------------------------------------------------------------------

    \156\ See proposed Section 12(e)(2), which is materially 
identical to Cboe Rule 5.73(e)(2).
---------------------------------------------------------------------------

    <bullet> Price Improvement With Auto-Match: If the FLEX PIM auction 
results in price improvement for the Agency Order and the Initiating 
Member selected auto-match, at each price better than the final auction 
price up to the designated limit price, the System executes the Agency 
Order against the Initiating Order for the number of contracts equal to 
the aggregate size of all FLEX PIM responses and then executes the 
Agency Order against those responses in the order set forth in proposed 
subparagraph (e)(2) described above. At the final auction price, the 
System executes contracts at that price in the order set forth in 
proposed subparagraph (e)(1) described above.\157\
---------------------------------------------------------------------------

    \157\ See proposed Section 12(e)(3), which is materially 
identical to Cboe Rule 5.73(e)(3).
---------------------------------------------------------------------------

    <bullet> Guaranteed Allocation: If the Initiating Member selects a 
single-price submission, it may elect for the Initiating Order to have 
less than their guaranteed allocation (50% if there is a response(s) 
from one other Member or 40% if there are responses from two or more 
Members) to trade against the Agency Order. The Initiating Member may 
select a lesser percentage than their guaranteed allocation. If the 
Initiating Member elects 0%, then notwithstanding subparagraphs (e)(1) 
and (2), the System only executes the Initiating Order against any 
remaining Agency Order contracts at the stop price after the Agency 
Order is allocated to all FLEX PIM responses at all prices equal to or 
better than the stop price. Guaranteed allocation information is not 
available to other market participants and may not be modified after it 
is submitted.\158\
---------------------------------------------------------------------------

    \158\ See proposed Section 12(e)(4), which is based on Cboe Rule 
5.73(e)(4) except the Exchange will replace Cboe's last priority 
feature with a guaranteed allocation feature similar to current PIM 
functionality that allows Members to request a lower percentage than 
their guaranteed allocation. See Options 3, Section 13(d)(3). As 
such, the difference between Cboe's rule and ISE's rule will be that 
ISE Members will be able to customize their guaranteed allocation 
percentages for FLEX PIM (which will follow the non-FLEX PIM 
process) while Cboe's rules do not seem to allow this for FLEX AIM. 
The Exchange notes that the proposed guaranteed allocation 
percentages of 50% (if there is a response(s) from one other Member) 
and 40% (if there are responses from two or more Members) for FLEX 
PIM will differ from the current guaranteed allocation percentage of 
40% for standard PIM. As such, the Exchange is aligning to Cboe's 
allocation percentages. The Exchange also notes that its affiliates, 
Nasdaq BX, Inc. (``BX'') and Nasdaq PHLX LLC (``Phlx''), have 
consistent guaranteed allocation percentages for their standard non-
FLEX price improvement auctions, BX PRISM and Phlx PIXL. See BX 
Options 3, Section 13(ii)(A)(1) and Phlx Options 3, Section 
13(b)(5)(B).
---------------------------------------------------------------------------

    Pursuant to proposed Section 12(e)(5), the System cancels any 
unexecuted FLEX PIM responses (or unexecuted portions) at the 
conclusion of the FLEX PIM auction.\159\
---------------------------------------------------------------------------

    \159\ See Cboe Rule 5.73(e)(5) for substantially similar 
provisions.
---------------------------------------------------------------------------

    Lastly, the Exchange proposes a number of policies applicable to 
FLEX PIM as Supplementary Materials to Options 3A, Section 12. 
Specifically, proposed Supplementary Material .01 will provide that a 
Member may only use a FLEX PIM auction where there is a genuine 
intention to execute a bona fide transaction.\160\ Proposed 
Supplementary Material .02 will provide that it will be deemed conduct 
inconsistent with just and equitable principles of trade and a 
violation of Options 9, Section 1 \161\ to engage in a pattern of 
conduct where the Initiating Member breaks up an Agency Order into 
separate orders for the purpose of gaining a higher allocation 
percentage than the Initiating Member would have otherwise received in 
accordance with the allocation procedures contained in proposed 
paragraph (e) above.\162\ Lastly, proposed Supplementary Material .03 
will provide that if an allocation would result in less than one 
contract, then one contract will be allocated.\163\ This aligns to how 
the Exchange currently allocates contracts in PIM.\164\
---------------------------------------------------------------------------

    \160\ See Cboe Rule 5.73, Interpretations and Policies .01 for 
materially identical provisions.
    \161\ Options 9, Section 1 provides that no Member shall engage 
in acts or practices inconsistent with just and equitable principles 
of trade. Persons associated with Members shall have the same duties 
and obligations as Members under the Rules of Options 9.
    \162\ See Cboe Rule 5.73, Interpretations and Policies .02 for 
materially identical provisions.
    \163\ The Exchange notes that it is not proposing to add the 
provision from Cboe Rule 5.73, Interpretations and Policies .03 that 
states: ``A FLEX Official may nullify a transaction following a FLEX 
AIM Auction pursuant to Rule 5.75(b).'' Because the FLEX Official is 
a floor concept and the Exchange does not operate a trading floor, 
the Exchange will not incorporate this concept into its proposed 
FLEX rules. Instead, the Exchange will System-enforce this provision 
by rejecting a FLEX PIM auction that does not comply with the 
provisions in proposed Options 3A, Section 12.
    \164\ See Supplementary Material .10 to Options 3, Section 13.
---------------------------------------------------------------------------

N. FLEX SOM (Section 13)

    The Exchange proposes to establish SOM auction functionality for 
FLEX Options in Options 3A, Section 13. The proposed FLEX SOM auction 
will be substantially similar to Cboe's FLEX SAM in Cboe Rule 5.74, 
except for certain intended differences to align with the Exchange's 
current System functionality for non-FLEX Options, as further described 
below. Pursuant to proposed Section 13, a Member (the ``Initiating 
Member'') may electronically submit for execution an order (which may 
be a simple or complex order) it represents as agent (``Agency Order'') 
against a solicited order (``Solicited Order'') if it submits the 
Agency Order for electronic execution into a FLEX SOM auction pursuant 
to this Rule.\165\
---------------------------------------------------------------------------

    \165\ See Cboe Rule 5.74 for similar provisions, except the 
Exchange will not add Cboe's language that the Solicited Order 
cannot have a Capacity F (i.e., Firm capacity) for the same 
executing firm ID (``EFID'') as the Agency Order for the foregoing 
reasons. Facilitated orders cannot be entered into FLEX SOM (just 
like they cannot be entered into standard SOM today). Since an order 
with the capacity of Firm can be valid for a solicitation order, the 
Exchange will not System enforce the rejection of Firm capacity 
orders to avoid the rejection of contra-side orders that are entered 
with a Firm capacity and are, in fact, solicitations at the outset. 
Instead, it will monitor for compliance with the requirement that 
the contra-side order be a solicitation rather than a facilitation 
through surveillance, as it does today for non-FLEX SOM. The 
applicable rule for the foregoing requirement will be set forth in 
Supplementary Material .02 to Options 3A, Section 13.
---------------------------------------------------------------------------

    Proposed Section 13(a)(1)-(6) will set forth the FLEX SOM auction 
eligibility requirements, and will be substantially similar to Cboe 
Rule 5.74(a)(1)-(6) except as noted below. Specifically, the Initiating 
Member may initiate a FLEX SOM auction if all of the following 
conditions are met:
    <bullet> Class. An Agency Order must in a FLEX Option class the 
Exchange designates as eligible for FLEX SOM auctions.
    <bullet> FLEX Option Series. The Agency Order and Solicited Order 
must each be a FLEX Order that complies with proposed Section 11(a) in 
a permissible FLEX Option series that complies with proposed Section 3 
above. For a complex FLEX Order, each leg must be in a permissible FLEX 
option series that complies with Section 3 above.\166\
---------------------------------------------------------------------------

    \166\ See Cboe Rule 5.74(a)(2) for similar provisions, except 
the Exchange will add a similar stipulation for each leg of a 
complex FLEX Order for clarity.
---------------------------------------------------------------------------

    <bullet> Marking. The Initiating Member must mark an Agency Order 
for FLEX SOM auction processing.
    <bullet> Size. The Agency Order must be for at least the minimum 
size designated by the Exchange (which may not be less than 500 
standard option contracts). For complex FLEX Orders, this minimum size 
requirement will apply to each leg. The Solicited Order must be for the 
same size as the Agency Order. The System handles each of the Agency 
Order and the Solicited Order as all-or-none.\167\
---------------------------------------------------------------------------

    \167\ See Cboe Rule 5.74(a)(4) for similar provisions except 
unlike Cboe, the Exchange will not allow the Solicited Order to be 
comprised of multiple solicited orders in FLEX SOM to be consistent 
with current non-FLEX SOM functionality in Options 3, Section 11(d). 
In addition, the Exchange will not incorporate Cboe's provisions 
relating to mini options or Micro FLEX Index Options into proposed 
Section 13(a)(4) as the Exchange does not list these products today. 
Further, the Exchange is adding a minor clarification that the 
minimum size requirement will apply to each leg of a complex FLEX 
Order.

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

[[Page 95000]]

    <bullet> Minimum Increment. The price of the Agency Order and 
Solicited Order for simple FLEX Orders must be in an increment the 
Exchange determines on a class basis (which may not be smaller than the 
amounts set forth in Section 5 above). If the Agency Order and 
Solicited Order are complex orders, the price must be a net price for 
the complex strategy.\168\ While the Exchange will align to Cboe's 
minimum increment requirements (i.e., $0.01) for the individual options 
legs of a complex FLEX Order entered into a FLEX SOM, the Exchange also 
proposes to align the minimum increment requirements for stock-tied 
FLEX complex strategies with the existing requirements for stock-tied 
non-FLEX complex strategies as set forth in Options 3, Section 
14(c)(1). As such, proposed Options 3A, Section 12(a)(5) will further 
provide that the prices of Complex Options Strategies (as defined in 
Options 3, Section 14) may be expressed in one cent ($0.01) increments, 
and the options leg of Complex Options Strategies may be executed in no 
smaller than one cent ($0.01) increments, regardless of the minimum 
increments otherwise applicable to the individual options legs of the 
order. Prices of Stock-Option Strategies or Stock-Complex Strategies 
(each as defined in Options 3, Section 14) may be expressed in any 
decimal price determined by the Exchange,\169\ and the stock leg of a 
Stock-Option Strategy or Stock-Complex Strategy may be executed in any 
decimal price permitted in the equity market. The options leg of a 
Stock-Option Strategy or Stock-Complex Strategy may be executed in no 
smaller than one cent ($0.01) increments, regardless of the minimum 
increments otherwise applicable to the individual options legs of the 
order. Similar to stock-tied complex orders today, the Exchange 
believes that smaller minimum increments are appropriate for complex 
FLEX Orders that contain a stock component as the stock component can 
trade at finer decimal increments permitted by the equity market.
---------------------------------------------------------------------------

    \168\ The Exchange notes that unlike Cboe, it will not allow 
prices to be entered as a percentage value, and therefore will not 
incorporate the applicable language from Cboe Rule 5.74(a)(5) into 
proposed Section 13(a)(5). As discussed above, the Exchange will 
also incorporate existing minimum increment requirements for non-
FLEX complex orders into proposed Section 13(a)(5) to align the 
proposed FLEX functionality with non-FLEX functionality.
    \169\ The prices for FLEX Stock-Option Strategies and FLEX 
Stock-Complex Strategies can be expressed to four decimal places, 
which is identical to how the stock portion of a non-FLEX Stock-
Option Strategy and a non-FLEX Stock-Complex Strategy can be priced 
today. See supra note 101.
---------------------------------------------------------------------------

    <bullet> An Initiating Member may only submit an Agency Order to a 
FLEX SOM auction after trading in FLEX Options is open pursuant to 
proposed Section 8.
    The System will reject or cancel both an Agency Order and Solicited 
Order submitted to a FLEX SOM auction that do not meet the conditions 
in proposed paragraph (a) as described above.
    Pursuant to proposed Section 13(b), the Solicited Order must stop 
the entire Agency Order at a specified price. If the Agency Order and 
Solicited Order are complex orders, the price must be a net price for 
the complex strategy. The Initiating Member must specify a single price 
at which it seeks to execute the Agency Order against the Solicited 
Order. Otherwise, the System will reject or cancel both an Agency Order 
and Solicited Order submitted to a FLEX SOM auction that do not meet 
this condition.\170\
---------------------------------------------------------------------------

    \170\ See Cboe Rule 5.74(b) for similar provisions, except the 
Exchange will not allow prices to be entered as a percentage value, 
and therefore will not incorporate the applicable language from 
Cboe's rule into proposed Section 13(b).
---------------------------------------------------------------------------

    Proposed Section 13(c) will govern the FLEX SOM auction process. 
Specifically, upon receipt of an Agency Order that meets the conditions 
in paragraphs (a) and (b) as described above, the FLEX SOM auction 
process commences. Proposed subparagraphs (c)(1)(A) and (B) will 
describe concurrent FLEX SOM auctions for simple Agency Orders and 
complex Agency Orders, respectively, and will be materially identical 
to Cboe Rule 5.74(c)(1)(A) and (B).
    One or more FLEX SOM auctions in the same FLEX Option series or 
same complex strategy (as applicable) may occur at the same time.\171\ 
To the extent there is more than one FLEX SOM auction in a FLEX Option 
series or complex strategy (as applicable) underway at the same time, 
the FLEX SOM auctions will conclude sequentially based on the times at 
which the FLEX SOM auction periods end. At the time each FLEX SOM 
auction concludes, the System allocates the Agency Order pursuant to 
proposed paragraph (e) as described below, and takes into account all 
FLEX SOM responses received during the FLEX SOM auction period. As 
noted above, the proposed concurrent FLEX SOM auction feature is 
consistent with Cboe's concurrent FLEX SAM auctions feature in Cboe 
Rule 5.74(c)(1), and is also consistent with the concurrent auction 
feature proposed above for FLEX Auctions and FLEX PIM. For the same 
reasons stated above for FLEX Auctions and FLEX PIM, the Exchange 
believes that providing this concurrent auction functionality for FLEX 
SOM may provide additional opportunities for execution of FLEX Orders 
by encouraging Members to use FLEX SOM.
---------------------------------------------------------------------------

    \171\ Further, for complex Agency Orders, SOM auctions in 
different complex strategies may be ongoing at any given time, even 
if the complex strategies have overlapping components. A FLEX SOM 
auction in a complex strategy may be ongoing at the same time as a 
FLEX SOM auction in any component of the complex strategy. See 
proposed subparagraph (c)(1)(B)(i) of Options 3A, Section 13.
---------------------------------------------------------------------------

    Pursuant to proposed Section 13(c)(2), the System initiates the 
FLEX SOM auction process by sending a FLEX SOM auction notification 
message detailing the side, size, price, capacity, auction ID, the 
length of the FLEX SOM auction period, and FLEX Option series or 
complex strategy, as applicable, of the Agency Order to all Members 
that elect to receive FLEX SOM auction notification messages. Similar 
to all other auction notifications, FLEX SOM auction notification 
messages will not be disseminated to OPRA. These provisions are 
materially identical to Cboe Rule 5.74(c)(2).
    Proposed Section 13(c)(3) will describe the ``FLEX SOM Auction 
period,'' and is based on Cboe Rule 5.74(c)(3). The FLEX SOM Auction 
period will be defined as a period of time that must be designated by 
the Initiating Member, which may be no less than three seconds and no 
more than five minutes. Similar to the exposure interval for electronic 
FLEX Auctions in Section 11(b) and the FLEX PIM Auction period in 
Section 12(c)(3) as discussed above, the Initiating Member will be 
required to identify a length of time within the specified parameters 
for FLEX SOM as there will be no default for the FLEX SOM Auction 
period. Otherwise, their FLEX Order will be rejected by the System. 
Further, if the designated length of the FLEX SOM Auction period 
exceeds the market close, then the auction will end at the market close 
with an execution, if an execution is permitted by this Section 13. 
Cboe's rule does not specify whether an execution (if permitted) would 
occur if the designated length exceeds the market close. However, the 
Exchange's non-FLEX auctions currently allow executions (as permitted 
by their respective rules) to occur in such scenarios, so the Exchange 
proposes to be consistent with current

[[Page 95001]]

System functionality in this regard.\172\ In doing so, the Exchange's 
proposal will promote executions in FLEX SOM (instead of cancelling the 
FLEX Order) while also preventing executions from occurring after the 
market close.
---------------------------------------------------------------------------

    \172\ While this behavior is not explicitly stated in the 
current Rules, the Exchange's proposal will be consistent with 
current non-FLEX auction behavior, including current PIM and SOM 
behavior.
---------------------------------------------------------------------------

    Proposed Section 13(c)(4) will provide that an Initiating Member 
may not modify an Agency Order or Solicited Order after submission to a 
FLEX SOM auction. This will be similar to Cboe Rule 5.74(c)(4) except 
unlike Cboe, the Exchange will allow Initiating Members to cancel their 
Agency Orders and Solicited Orders upon submission into a FLEX SOM, 
which will align with current SOM functionality.\173\
---------------------------------------------------------------------------

    \173\ This feature is not explicitly stated in the current SOM 
rules in Options 3, Section 11(d), but it is consistent with current 
SOM functionality.
---------------------------------------------------------------------------

    Proposed Section 13(c)(5) will govern the requirements for FLEX SOM 
responses. Specifically:
    <bullet> Any Member other than the Initiating Member (the response 
cannot have the same badge/mnemonic as the Agency Order) may submit 
responses to a FLEX SOM auction that are properly marked specifying 
size, side, price, and the auction ID for the FLEX SOM auction to which 
the Member is submitting the response. A FLEX SOM response may only 
participate in the FLEX SOM auction with the auction ID specified in 
the response.\174\
---------------------------------------------------------------------------

    \174\ See proposed Options 3A, Section 13(c)(5), which is based 
on Cboe Rule 5.74(c)(5).
---------------------------------------------------------------------------

    <bullet> The minimum price increment for FLEX SOM responses is the 
same as the one the Exchange determines for a class pursuant to 
proposed Section 12(a)(5) above. A response to a FLEX SOM auction of a 
complex Agency Order must have a net price. The System will reject a 
FLEX SOM response that is not in the applicable minimum increment.\175\
---------------------------------------------------------------------------

    \175\ See proposed Options 3A, Section 13(c)(5)(A), which is 
based on Cboe Rule 5.74(c)(5)(A) except the Exchange will not allow 
prices to be expressed as a percentage value.
---------------------------------------------------------------------------

    <bullet> A Member using the same badge/mnemonic may only submit a 
single FLEX SOM response per auction ID for a given auction. If an 
additional SOM response is submitted for the same auction ID from the 
same badge/mnemonic, then that FLEX SOM response will automatically 
replace the previous FLEX SOM response.\176\
---------------------------------------------------------------------------

    \176\ See proposed Options 3A, Section 13(c)(5)(B), which will 
be different from Cboe Rule 5.74(c)(5)(B) because the Exchange will 
not allow Members to submit multiple FLEX SOM responses using the 
same badge/mnemonic, and will not aggregate all of the Member's FLEX 
SOM responses. While the Exchange's standard non-FLEX rules are 
currently silent in this regard, the Exchange is making these 
concepts clear in the proposed FLEX language. Ultimately the 
Exchange's proposed FLEX SOM functionality in this regard will align 
to current non-FLEX auction functionality, including SOM auctions in 
Options 3, Section 11(d).
---------------------------------------------------------------------------

    <bullet> The System will cap the size of a FLEX SOM response at the 
size of the Agency Order (i.e., the System will ignore size in excess 
of the size of the Agency Order when processing the FLEX SOM 
auction).\177\
---------------------------------------------------------------------------

    \177\ See proposed Options 3A, Section 13(c)(5)(C), which is 
based on Cboe Rule 5.74(c)(5)(C) except the Exchange will not allow 
Members to submit multiple FLEX SOM responses using the same badge/
mnemonic, and will not aggregate all of the Member's FLEX SOM 
responses. As noted above, this will align to current non-FLEX 
auction functionality, including SOM auctions in Options 3, Section 
11(d).
---------------------------------------------------------------------------

    <bullet> FLEX SOM responses must be on the opposite side of the 
market as the Agency Order. The System rejects a FLEX SOM response on 
the same side of the market as the Agency Order.\178\
---------------------------------------------------------------------------

    \178\ See proposed Options 3A, Section 13(c)(5)(D), which is 
materially identical to Cboe Rule 5.74(c)(5)(D).
---------------------------------------------------------------------------

    <bullet> FLEX SOM responses will not be visible to FLEX SOM auction 
participants or disseminated to OPRA.\179\
---------------------------------------------------------------------------

    \179\ See proposed Options 3A, Section 13(c)(5)(E), which is 
materially identical to Cboe Rule 5.74(c)(5)(E).
---------------------------------------------------------------------------

    <bullet> A Member may modify or cancel its FLEX SOM responses 
during a FLEX SOM auction.\180\
---------------------------------------------------------------------------

    \180\ See proposed Options 3A, Section 13(c)(5)(F), which is 
materially identical to Cboe Rule 5.74(c)(5)(F).
---------------------------------------------------------------------------

    Pursuant to proposed Section 13(d), a FLEX SOM auction concludes at 
the earliest to occur of the following times: (1) the end of the FLEX 
SOM auction period; and (2) any time the Exchange halts trading in the 
affected underlying, provided, however, that in such instance the FLEX 
SOM auction concludes without execution.\181\
---------------------------------------------------------------------------

    \181\ See Cboe Rule 5.74(d) for similar provisions, except the 
Exchange will make a minor clarification that this rule applies when 
the Exchange halts trading in the affected underlying (and not 
series, which is what Cboe currently has in its rule).
---------------------------------------------------------------------------

    Proposed Section 13(e) will govern how executions will occur in 
FLEX SOM. In particular, at the end of the FLEX SOM auction, the System 
will execute the Agency Order against the Solicited Order or FLEX SOM 
responses at the best price(s) as follows. For purposes of ranking the 
Solicited Order and FLEX SOM responses when determining how to allocate 
the Agency Order against the Solicited Order and those responses, the 
term ``price'' refers to the dollar and decimal amount of the order or 
response bid or offer.\182\ Proposed subparagraphs (e)(1)-(3) detail 
the FLEX SOM allocation methodology for the following scenarios:
---------------------------------------------------------------------------

    \182\ See Cboe Rule 5.74(e) for similar provisions except the 
Exchange will not allow prices to be expressed as a percentage 
value.
---------------------------------------------------------------------------

    <bullet> Execution Against Solicited Order: The System executes the 
Agency Order against the Solicited Order at the stop price if there are 
no Priority Customer FLEX SOM responses and the aggregate size of FLEX 
SOM responses at an improved price(s) is insufficient to satisfy the 
Agency Order.\183\
---------------------------------------------------------------------------

    \183\ See proposed Section 13(e)(1), which is materially 
identical to Cboe Rule 5.74(e)(1).
---------------------------------------------------------------------------

    <bullet> Execution Against FLEX SOM Responses: The System executes 
the Agency Order against FLEX SOM responses if (1) there is a Priority 
Customer FLEX SOM response and the aggregate size of that response and 
all other FLEX SOM responses is sufficient to satisfy the Agency Order 
or (2) the aggregate size of FLEX SOM responses at an improved price(s) 
is sufficient to satisfy the Agency Order. The Agency Order executes 
against FLEX SOM responses at each price level. At the price at which 
the balance of the Agency Order can be fully executed, in the following 
order:
    <bullet> Priority Customer FLEX SOM responses (in time priority); 
\184\ and
---------------------------------------------------------------------------

    \184\ See proposed Section 13(e)(2)(A), which is materially 
identical to Cboe Rule 5.74(e)(2)(A).
---------------------------------------------------------------------------

    <bullet> All other FLEX SOM responses, allocated on a Size Pro-Rata 
basis (as defined in Options 3, Section 10(c)).\185\
---------------------------------------------------------------------------

    \185\ See proposed Section 13(e)(2)(B), which is materially 
identical to Cboe Rule 5.74(e)(2)(B). The Exchange notes that Size 
Pro-Rata (as defined in Options 3, Section 10(c)) is similar to pro-
rata as referenced in the Cboe rule (and as defined in Cboe Rule 
5.32(a)(1)(B)).
---------------------------------------------------------------------------

    <bullet> No Execution: The System will cancel the Agency Order and 
Solicited Order with no execution if there is a Priority Customer FLEX 
SOM response and the aggregate size of that response and other FLEX SOM 
responses is insufficient to satisfy the Agency Order.\186\
---------------------------------------------------------------------------

    \186\ See proposed Section 13(e)(3), which is materially 
identical to Cboe Rule 5.74(e)(3).
---------------------------------------------------------------------------

    Pursuant to proposed Section 12(e)(4), the System cancels any 
unexecuted FLEX SOM responses (or unexecuted portions) at the 
conclusion of a FLEX SOM auction.\187\
---------------------------------------------------------------------------

    \187\ See Cboe Rule 5.74(e)(4) for substantially similar 
provisions.
---------------------------------------------------------------------------

    Lastly, the Exchange proposes a number of policies applicable to 
FLEX SOM as Supplementary Materials to Options 3A, Section 13. 
Specifically, proposed Supplementary Material .01 will provide that 
prior to entering Agency Orders into a FLEX SOM auction on behalf of 
customers, Initiating Members must deliver to the customer a written 
notification informing the customer that its order

[[Page 95002]]

may be executed using the FLEX SOM Auction. The written notification 
must disclose the terms and conditions contained in this Rule and be in 
a form approved by the Exchange.\188\ Proposed Supplementary Material 
.02 will provide that under this Rule, Initiating Members may enter 
contra-side orders that are solicited. FLEX SOM provides a facility for 
Members that locate liquidity for their customer orders. Members may 
not use the FLEX SOM auction to circumvent Options 3, Section 22(b) 
limiting principal transactions. This may include, but is not limited 
to, Members entering contra-side orders that are solicited from (1) 
affiliated broker-dealers, or (2) broker-dealers with which the Member 
has an arrangement that allows the Member to realize similar economic 
benefits from the solicited transaction as it would achieve by 
executing the customer order in whole or in part as principal. 
Additionally, any solicited contra-side orders entered by Members to 
trade against Agency Orders may not be for the account of an Exchange 
Market Maker that is assigned to the options class.\189\ Lastly, 
proposed Supplementary Material .03 will provide that if an allocation 
would result in less than one contract, then one contract will be 
allocated.\190\ This aligns to how the Exchange currently allocates 
contracts in SOM.\191\
---------------------------------------------------------------------------

    \188\ See Cboe Rule 5.74, Interpretations and Policies .01 for 
materially identical provisions.
    \189\ See Cboe Rule 5.74, Interpretations and Policies .02 for 
similar provisions. The Exchange is also adding a prohibition 
against solicited contra-side orders being for the account of an 
Exchange Market Maker assigned to the options class to align with 
the current prohibition in Supplementary Material .03 to Options 3, 
Section 11.
    \190\ The Exchange notes that it is not proposing to add the 
provision from Cboe Rule 5.74, Interpretations and Policies .03 that 
states: ``A FLEX Official may nullify a transaction following a FLEX 
SAM Auction pursuant to Rule 5.75(b).'' Because the FLEX Official is 
a floor concept and the Exchange does not operate a trading floor, 
the Exchange will not incorporate this concept into its proposed 
FLEX rules. Instead, the Exchange will System-enforce this provision 
by rejecting a FLEX SAM auction that does not comply with the 
provisions in proposed Options 3A, Section 13.
    \191\ See Supplementary Material .09 to Options 3, Section 11.
---------------------------------------------------------------------------

O. Risk Protections (Section 14)

    The Exchange proposes in Options 3A, Section 14 to specify which of 
the Exchange's risk protections apply to FLEX trading. Risk protections 
are protections in our System to help minimize risk. The risk 
protections specified in proposed Options 3A, Sections 14(a) and 14(b) 
are mandatory whereas the risk protections specified in proposed 
Options 3A, Section 14(c) are optional. Proposed Section 14(a) will 
provide that the following simple order risk protections (as described 
in Options 3, Section 15) are available to FLEX Options: Market Wide 
Risk Protection and Size Limitation.\192\ As set forth in Options 3, 
Section 15(a)(1)(C), Market Wide Risk Protections are mandatory 
activity-based protections that allow Members to establish limits for 
order entry and execution rate during a specified period of time. The 
System maintains separate counts for each of the thresholds specified 
in the rule over rolling periods of time.\193\ Upon triggering the 
specified limits, the System will either delete all open orders and 
prevent entry of new orders for the Member, or prevent entry of new 
orders for the Member. Similar to how Market Wide Risk Protection 
assists Members in better managing their risk in the standard non-FLEX 
market on ISE today, the Exchange believes that applying Market Wide 
Risk Protection to its FLEX market will be beneficial for Members using 
FLEX trading.
---------------------------------------------------------------------------

    \192\ Size Limitation for simple orders is a limit on the number 
of contracts an incoming order may specify. Orders that exceed the 
maximum number of contracts are rejected. The maximum number of 
contracts, which shall not be less than 10,000, is established by 
the Exchange from time-to-time. See Options 3, Section 15(a)(2)(B).
    \193\ As set out in Options 3, Section 15(a)(1)(C), the Market 
Wide Risk Protection will have counting programs that will maintain 
separate counts, over rolling time periods specified by the Member 
for each count, of: (1) the total number of orders entered in the 
regular order book; (2) the total number of orders entered in the 
complex order book with only options legs; (3) the total number of 
Stock-Option and Stock-Complex Orders; (4) the total number of 
contracts traded in regular orders; (5) the total number of 
contracts traded in Complex Options Orders; and (6) the total number 
of contracts traded in Stock-Option and Stock-Complex Orders. As 
applied to FLEX, only items (4) through (6) of the foregoing will 
apply. Items (1) through (3) will not apply to FLEX because there is 
no order book for FLEX. The Exchange notes that Options 3, Section 
15(a)(1)(C)(5) (i.e., item (5) of the foregoing) presently refers to 
Stock-Option and Stock Complex Orders, instead of Complex Options 
Orders. However, ISE will file a clean-up amendment so that 
subparagraph (5) will refer instead to Complex Options Orders. This 
clean-up will align ISE's rule to MRX Options 3, Section 
15(a)(1)(C).
---------------------------------------------------------------------------

    Proposed Section 14(b) will provide that the following complex 
order risk protections (as described in Options 3, Section 16) are 
available to FLEX Options: Strategy Protections (only to FLEX Auctions 
and FLEX responses in proposed Options 3A, Section 11(b)), Size 
Limitation,\194\ the Price Limit for Complex Order protections as 
appliable to the stock component (as described in Options 3, Section 
16(a)),\195\ the Stock-Tied NBBO protections (as described in Options 
3, Section 16(d)),\196\ and the Stock-Tied Reg SHO protections (as 
described in Options 3, Section 16(e)).\197\
---------------------------------------------------------------------------

    \194\ Size Limitation for complex orders is a limit on the 
number of contracts (and shares in the case of a Stock-Option 
Strategy or Stock-Complex Strategy) any single leg of an incoming 
Complex Order may specify. Orders that exceed the maximum number of 
contracts (or shares) are rejected. The maximum number of contracts 
(or shares), which shall not be less than 10,000 (or 100,000 
shares), is established by the Exchange from time-to-time. See 
Options 3, Section 16 (c)(2).
    \195\ The Exchange amended the Price Limits for Complex Order 
protections in Options 3, Section 16(a) for its standard non-FLEX 
complex market as part of the technology migration to enhanced 
Nasdaq functionality discussed above. See supra note 11. See also 
Securities Exchange Act Release No. 98066 (August 7, 2023), 88 FR 
54672 (August 11, 2023) (SR-ISE-2023-13).
    \196\ The Exchange introduced the Stock-Tied NBBO protections in 
Options 3, Section 16(d) for its standard non-FLEX complex market as 
part of the technology migration to enhanced Nasdaq functionality 
discussed above. See supra note 11. See also Securities Exchange Act 
Release No. 98066 (August 7, 2023), 88 FR 54672 (August 11, 2023) 
(SR-ISE-2023-13).
    \197\ The Exchange introduced the Stock-Tied Reg SHO protections 
in Options 3, Section 16(e) for its standard non-FLEX complex market 
as part of the technology migration to enhanced Nasdaq functionality 
discussed above. See supra note 11. See also Securities Exchange Act 
Release No. 98066 (August 7, 2023), 88 FR 54672 (August 11, 2023) 
(SR-ISE-2023-13).
---------------------------------------------------------------------------

    The Strategy Protections listed in Options 3, Section 16(b) are the 
Vertical Spread Protection,\198\ Calendar Spread Protection,\199\ 
Butterfly Spread Protection,\200\ and Box Spread Protection.\201\ These 
Strategy Protections are all aimed at preventing the potential 
execution of the specified complex strategies (i.e., vertical spread, 
calendar spread, butterfly spread, and box spread) outside of specified 
price parameters in order to prevent executions at undesirable prices. 
Today, Strategy Protections do not apply to

[[Page 95003]]

orders and responses submitted into non-FLEX PIM and non-FLEX SOM.\202\ 
The Exchange will align this application to FLEX such that Strategy 
Protections would only apply to FLEX Auctions and FLEX responses in 
proposed Section 11(b) as described above, and not to FLEX Orders and 
responses submitted into FLEX PIM and FLEX SOM.
---------------------------------------------------------------------------

    \198\ The Vertical Spread Protection will apply to a vertical 
spread. A vertical spread is an order to buy a call (put) option and 
to sell another call (put) option in the same security with the same 
expiration but at a higher (lower) strike price. See Options 3, 
Section 16(b)(1).
    \199\ The Calendar Spread Protection will apply to a Calendar 
Spread. A calendar spread is an order to buy a call (put) option 
with a longer expiration and to sell another call (put) option with 
a shorter expiration in the same security at the same strike price. 
See Options 3, Section 16(b)(2).
    \200\ The Butterfly Spread Protection will apply to a butterfly 
spread. A butterfly spread is a three legged Complex Order with the 
following: (1) two legs to buy (sell) the same number of calls 
(puts); (2) one leg to sell (buy) twice the number of calls (puts) 
with a strike price at mid-point of the two legs to buy (sell); (3) 
all legs have the same expiration; and (4) each leg strike price is 
equidistant from the next sequential strike price. See Options 3, 
Section 16(b)(3).
    \201\ The Box Spread Protection will apply to a box spread. A 
box spread is a four legged Complex Order with the following: (1) 
one pair of legs with the same strike price with one leg to buy a 
call (put) and one leg to sell a put (call); (2) a second pair of 
legs with a different strike price from the pair described in (1) 
with one leg to sell a call (put) and one leg to buy a put (call); 
(3) all legs have the same expiration; and (4) all legs have equal 
volume. See Options 3, Section 16(b)(4).
    \202\ See Options 3, Section 16(b), which describes the non-
applicability of the Strategy Protections to certain auction 
mechanisms. See also Securities Exchange Act Release No. 100743 
(August 16, 2024), 89 FR 68014 (August 22, 2024) (SR-ISE-2024-39) 
(effective but not yet operative). As amended by SR-ISE-2024-39, 
Options 3, Section 16(b) would provide that the Strategy Protections 
will not apply when a standard non-FLEX complex order includes at 
least one p.m.-settled leg and at least one a.m.-settled leg. This 
would likewise be true for complex FLEX Orders (i.e., the Strategy 
Protections would not apply when a complex FLEX Order includes at 
least one p.m.-settled leg and at least one a.m.-settled leg).
---------------------------------------------------------------------------

    As noted above, the Exchange adopted the Price Limit for Complex 
Order protections in Options 3, Section 16(a),\203\ the Stock-Tied NBBO 
protections in Options 3, Section 16(d),\204\ and the Stock-Tied Reg 
SHO protections in Options 3, Section 16(e) \205\ (collectively, the 
``Stock-Tied Risk Protections'') as part of SR-ISE-2023-13 for its 
standard non-FLEX complex market. The Exchange is now proposing to 
apply the Stock-Tied Risk Protections to complex FLEX Orders to the 
extent the complex FLEX Order has a stock component. The Price Limits 
for Complex Orders in Options 3, Section 16(a) seek to prevent complex 
executions from occurring outside of certain price limits that are tied 
to the NBBO for the options series or for any stock component. Because 
there will be no book for FLEX trading (and therefore no NBBO for the 
FLEX Options series), the Exchange will not apply the price limit 
protection tied to the NBBO for the options series for FLEX trading. To 
the extent the complex FLEX Order has a stock component, the Exchange 
will only apply the price limit protection tied to the NBBO for the 
stock component. The below is an example of how the Exchange will apply 
the Options 3, Section 16(a) price protection to complex FLEX Orders.
---------------------------------------------------------------------------

    \203\ Specifically, Options 3, Section 16(a) states that as 
provided in Options 3, Section 14(d)(2), the legs of a complex 
strategy may be executed at prices that are inferior to the prices 
available on other exchanges trading the same options series. 
Notwithstanding, the System will not permit any leg of a complex 
strategy to trade through the NBBO for the series or any stock 
component by a configurable amount calculated as the lesser of (i) 
an absolute amount not to exceed $0.10, and (ii) a percentage of the 
NBBO not to exceed 500%, as determined by the Exchange on a class, 
series or underlying basis. A Member can also include an instruction 
on a Complex Order that each leg of the Complex Order is to be 
executed only at a price that is equal to or better than the NBBO 
for the options series or any stock component, as applicable (``Do-
Not-Trade-Through'' or ``DNTT''). As discussed later in this filing, 
the NBBO price limit for the option series will not apply to complex 
FLEX orders; however, the NBBO price limit for the stock component 
will apply.
    \204\ Specifically, Options 3, Section 16(d) provides that for 
Complex Orders in Stock-Option Strategies and Stock-Complex 
Strategies, the Exchange shall electronically communicate the 
underlying security component of a Complex Order to Nasdaq Execution 
Services, LLC (``NES''), its designated broker dealer, for immediate 
execution. Such execution and reporting will not occur on the 
Exchange and will be handled by NES pursuant to applicable rules 
regarding equity trading. NES will ensure that the execution price 
is within the high-low range for the day in that stock at the time 
the Complex Order is processed and within a certain price from the 
current market pursuant to Options 3, Section 16(a). If the stock 
price is not within these parameters, the Complex Order is not 
executable and the Exchange will hold the Complex Order on the Order 
Book, if consistent with Member instructions. This risk protection 
will apply wholesale to complex FLEX Orders with a stock component.
    \205\ Specifically, Options 3, Section 16(e) provides that when 
the short sale price test in Rule 201 of Regulation SHO is triggered 
for a covered security, NES will not execute a short sale order in 
the underlying covered security component of a Complex Order if the 
price is equal to or below the current national best bid. However, 
NES will execute a short sale order in the underlying covered 
security component of a Complex Order if such order is marked 
``short exempt,'' regardless of whether it is at a price that is 
equal to or below the current national best bid. If NES cannot 
execute the underlying covered security component of a Complex Order 
in accordance with Rule 201 of Regulation SHO, the Exchange will 
hold the Complex Order on the Complex Order Book, if consistent with 
Member instructions. The order may execute at a price that is not 
equal to or below the current national best bid. For purposes of 
this paragraph, the term ``covered security'' shall have the same 
meaning as in Rule 201(a)(1) of Regulation SHO. This risk protection 
will apply wholesale to complex FLEX Orders with a stock component.
---------------------------------------------------------------------------

    Scenario illustrating applicability of the stock buffer described 
in Options 3, Section 16(a) Price Limits for Complex Orders:

IBM Underlying/Stock NBBO is 1.00 x 2.00
Stock buffer is configured to the lesser of $0.05 or 5%
FLEX Option NBBO does not exist, but the minimum trading increment/
minimum price variation (MPV) for option leg executions is $0.01

    <bullet> FLEX Auction is entered in a Stock-Complex Strategy 
encompassing 2 IBM FLEX Put options: Buy 1 Put (FLEX option leg A) + 
Buy 1 Put (FLEX option leg B) + Buy 100 shares IBM stock: Buy 110 units 
of the A + B + Stock strategy @net price of $1.02.
    <bullet> A firm responds to Sell 110 @net price of $0.89.

FLEX Auction timer passes & auction concludes

    <bullet> The firm's response trades with the FLEX Auction order 110 
@net price of $0.97 because the stock component cannot trade at any 
price lower than $0.95 ($1.00-$0.05 [price limit for stock component] = 
$0.95) and the FLEX option legs cannot trade at any price lower than 
$0.01 as this is the minimum trading increment for option legs; 
therefore, the minimum stock price of $0.95 plus the $0.01 minimum 
option leg price means that, despite the $0.89 limit price on the 
response, the strategy cannot trade below $0.97 ($0.95 + [$0.01*2 
legs]).
    As it relates to the other Stock-Tied Risk Protections (i.e., the 
Stock-Tied NBBO protections and the Stock-Tied Reg SHO protections), 
these will apply wholesale to complex FLEX Orders with a stock 
component as noted above.
    Proposed Section 14(c) will provide that the optional risk 
protections in Options 3, Section 28 are available to FLEX 
Options.\206\ In particular, the following are optional risk 
protections in Options 3, Section 28: (1) notional dollar value per 
order (which will be calculated as quantity multiplied by limit price 
multiplied by number of underlying shares), (2) daily aggregate 
notional dollar value, (3) quantity per order, and (4) daily aggregate 
quantity. In sum, Members may set thresholds for each of the foregoing 
protections in order to limit the quantity and notional value they can 
send per order and on aggregate for the day.
---------------------------------------------------------------------------

    \206\ The Exchange introduced the optional risk protections in 
Options 3, Section 28 as part of the technology migration to 
enhanced Nasdaq functionality discussed above. See Securities 
Exchange Act Release No. 96818 (February 6, 2023), 88 FR 8950 
(February 10, 2023) (SR-ISE-2023-06).
---------------------------------------------------------------------------

P. Data Feeds (Section 15)

    The Exchange proposes to specify in Options 3A, Section 15 which 
data feeds it will disseminate auction notifications for simple and 
complex FLEX Orders. Proposed Section 15(a) will provide that auction 
notifications for simple FLEX Orders will be disseminated through the 
Order Feed, as described in Options 3, Section 23(a)(2).\207\ Proposed 
Section 15(b) will provide that auction notifications for complex FLEX 
Orders will be disseminated through the Spread Feed, as described in 
Options 3, Section

[[Page 95004]]

23(a)(5).\208\ The Exchange notes that this aligns to current 
functionality where simple auction notifications are disseminated over 
the Order Feed and complex auction notifications are disseminated over 
the Spread Feed. Today, simple and complex auction notifications inform 
Members that an auction order has been accepted by the System and that 
an auction is commencing. Auction notifications also contain all of the 
relevant information Members need to respond to that particular 
auction.\209\ As proposed, the simple and complex FLEX auction 
notifications will likewise inform Members that a FLEX auction order 
has been accepted by the System, a FLEX auction is commencing, and will 
also contain all of the relevant information Members need to respond to 
that particular FLEX auction.\210\ The FLEX auction notifications will 
specify that a particular auction is FLEX versus non-FLEX. As is the 
case today for non-FLEX auctions, FLEX auction notifications 
disseminated over the Order Feed and the Spread Feed will be available 
to all Members that elect to receive such notification messages.
---------------------------------------------------------------------------

    \207\ The Nasdaq ISE Order Feed (``Order Feed'') provides 
information on new orders resting on the book (e.g. price, quantity 
and market participant capacity). In addition, the feed also 
announces all auctions. The data provided for each option series 
includes the symbols (series and underlying security), put or call 
indicator, expiration date, the strike price of the series, and 
whether the option series is available for trading on ISE and 
identifies if the series is available for closing transactions only. 
The feed also provides order imbalances on opening/reopening.
    \208\ Nasdaq ISE Spread Feed (``Spread Feed'') is a feed that 
consists of: (1) options orders for all Complex Orders (i.e., 
spreads, buy-writes, delta neutral strategies, etc.); (2) data 
aggregated at the top five price levels (BBO) on both the bid and 
offer side of the market; (3) last trades information. The Spread 
Feed provides updates, including prices, side, size and capacity, 
for every Complex Order placed on the ISE Complex Order book. The 
Spread Feed shows: (1) aggregate bid/ask quote size; (2) aggregate 
bid/ask quote size for Professional Customer Orders; and (3) 
aggregate bid/ask quote size for Priority Customer Orders for ISE 
traded options. The feed also provides Complex Order auction 
notifications. The Exchange notes that as applied to FLEX, the 
majority of the data elements in the Spread Feed will not applicable 
to FLEX Options (e.g., data aggregated at the top five price levels 
(BBO) on both the bid and offer side of the market and aggregate 
bid/ask quote size). While other data elements (e.g., options orders 
for all Complex Orders and last trades information) also apply to 
FLEX, the Exchange is pointing out auction notifications in the 
proposed rule to be transparent about the most salient feature for 
complex FLEX Orders.
    \209\ For example, at the commencement of a standard, non-FLEX 
PIM auction, the Exchange sends a broadcast message (i.e., auction 
notification) that includes the series, price and size of the Agency 
Order, and whether it is to buy or sell, through the Order Feed. See 
Options 3, Section 13(c).
    \210\ For example, at the commencement of a FLEX PIM Auction, 
the Exchange would send FLEX PIM Auction notification message 
detailing the side, size, auction ID, the length of the FLEX PIM 
Auction period, and FLEX Option series or complex strategy, as 
applicable, of the Agency Order to all Members that elect to receive 
FLEX PIM Auction notification messages. See proposed Options 3A, 
Section 12(c)(2).
---------------------------------------------------------------------------

Q. FLEX Market Makers (Section 16)

    Proposed Section 16 will govern FLEX Market Makers on the Exchange. 
Pursuant to proposed Section 16(a), a FLEX Market Maker will 
automatically receive an appointment in the same FLEX option class(es) 
as its non-FLEX class appointments selected pursuant to Options 2, 
Section 3.\211\ Only the Primary Market Maker in the non-FLEX Option 
may be the assigned Primary Market Maker in that FLEX Option.\212\ 
Today, in order for Market Makers to submit auction responses in option 
classes through SQF, they need to be appointed to that option 
class.\213\ As such, the Exchange is automatically carrying over the 
FLEX Market Maker's non-FLEX options class appointment as its FLEX 
option class appointment in order to allow the FLEX Market Maker to 
respond to the electronic FLEX Auction, FLEX PIM, and FLEX SOM as 
described above.
---------------------------------------------------------------------------

    \211\ See Cboe Rule 3.58(c) for materially identical provisions.
    \212\ The Exchange notes that this requirement is based on Phlx 
Options 8, Section 34(d)(1), which currently states that only the 
Lead Market Maker in the non-FLEX option may be the assigned 
Specialist in that FLEX option. Primary Market Maker on ISE is 
analogous to a Lead Market Maker on Phlx.
    \213\ See supra note 68 describing SQF features available in the 
Exchange's non-FLEX market today (including the ability for Market 
Makers to currently send auction responses). As discussed above, the 
Exchange is proposing to also allow FLEX auction responses through 
SQF.
---------------------------------------------------------------------------

    Proposed Section 16(b) will provide that each FLEX Market Maker 
must fulfill all the obligations of a Market Maker under Options 2 and 
must comply with the applicable provisions, except FLEX Market Makers 
do not need to provide continuous quotes in FLEX Options.\214\
---------------------------------------------------------------------------

    \214\ See Cboe Rule 5.57 for similar provisions related to FLEX 
Market Makers. The Exchange will not impose continuing quoting 
obligations on FLEX Market Makers (similar to Cboe) given that such 
obligations are relevant for book trading. As discussed above, there 
will be no book trading for FLEX Options. As discussed above, the 
Exchange will not incorporate provisions related to FLEX Officials 
like Cboe as this is generally a floor trading concept and the 
Exchange does not have a trading floor.
---------------------------------------------------------------------------

R. Letters of Guarantee (Section 17)

    The Exchange proposes in Options 3A, Section 17(a) to provide that 
no FLEX Market Maker shall effect any transaction in FLEX Options 
unless one or more effective Letter(s) of Guarantee has been issued by 
a Clearing Member and filed with the Exchange accepting financial 
responsibility for all FLEX transactions made by the FLEX Market Maker 
pursuant to Options 6, Section 4.\215\
---------------------------------------------------------------------------

    \215\ Options 6, Section 4 provides that no Market Maker shall 
make any transactions on the Exchange unless a Letter of Guarantee 
has been issued for such Member by a Clearing Member and filed with 
the Exchange, and unless such Letter of Guarantee has not been 
revoked pursuant to paragraph (c) of this Rule. A Letter of 
Guarantee shall provide that the issuing Clearing Member accepts 
financial responsibilities for all Exchange Transactions made by the 
guaranteed Member.
---------------------------------------------------------------------------

S. Position Limits (Section 18)

    The Exchange proposes to detail the position limits for FLEX 
Options in Options 3A, Section 18. As discussed below, proposed Section 
18 will be based on the FLEX Options position limit rules on Cboe and 
its own market.
    Proposed Section 18(a) will govern the position limits for FLEX 
Index Options. Specifically, proposed Section 18(a)(1) will provide 
that except as provided in proposed Section 18(a)(2)-(4) below, FLEX 
Index Options shall be subject to the same position limits governing 
index options as provided for in Options 4A, Sections 6 and 7.\216\ 
Proposed Section 18(a)(2) will provide that except as otherwise 
provided in subparagraph (a)(3) of this Rule, in no event shall the 
position limits for broad-based FLEX Index Options exceed 25,000 
contracts on the same side of the market.\217\ Proposed Section 
18(a)(3) will provide that there shall be no position limits for broad-
based index options listed in Options 4A, Section 6(a).\218\ However, 
each Member (other than FLEX Market Makers) that maintains a FLEX 
broad-based index option position on the same side of the market in 
excess of 100,000 contracts in NDX or RUT for its own account or for 
the account of a customer, shall report information as to whether the 
positions are hedged and provide documentation as to how such contracts 
are hedged, in the manner and form required by the Exchange. In 
calculating the applicable contract-reporting amount, reduced-value 
contracts will be aggregated with full-value contracts and counted by 
the amount by which they equal a full-value contract (e.g., 10 MNX 
options equal 1 NDX full-value contract). The Exchange may impose other 
reporting requirements as well as the limit at which the reporting 
requirement may be triggered.\219\ Whenever the Exchange

determines that additional margin is warranted in light of the risks 
associated with an under-hedged FLEX NDX or RUT options position, the 
Exchange may impose additional margin upon the account maintaining such 
under-hedged position pursuant to its authority under Options 6C, 
Section 5. The clearing firm carrying the account also will be subject 
to capital charges under Rule 15c3-1 under the Exchange Act to the 
extent of any margin deficiency resulting from the higher margin 
requirements.\220\
---------------------------------------------------------------------------

    \216\ Options 4A, Sections 6 and 7 presently set forth the 
position limits for broad-based and industry index options, 
respectively.
    \217\ This separate same side position limit for broad-based 
FLEX Index Options (except for the ones noted below) is based on the 
Exchange's same side position limit for its standard market as set 
forth in Options 4A, Section 6(a).
    \218\ As such the following broad-based index options listed in 
Options 4A, Section 6(a) will have no position limits for FLEX Index 
Options: options on the Nasdaq 100 Index, Mini Nasdaq 100 Index, 
Nations VolDex Index, Nasdaq 100 Reduced Value Index, and Nasdaq 
Micro Index Options.
    \219\ See Options 4A, Section 9(a)(13) (setting forth the same 
reporting requirements for the Exchange's standard non-FLEX index 
options market). See also Cboe Rule 8.35(b) for similar reporting 
requirements.
    \220\ See Options 4A, Section 9(a)(14) (setting forth the same 
stipulation for the Exchange's standard index options market). See 
also Cboe Rule 8.35(b) for similar stipulations.
---------------------------------------------------------------------------

    Proposed Section 18(a)(4) will provide that industry-based FLEX 
Index Options shall be subject to separate position limits of 18,000, 
24,000, or 31,500 contracts, depending on the position limit tier 
determined pursuant to Options 4A, Section 7(a)(1).\221\
---------------------------------------------------------------------------

    \221\ The proposed position limits align to the Exchange's non-
FLEX position limits for industry index options in Options 4A, 
Section 7(a)(1).
---------------------------------------------------------------------------

    Proposed Section 18(b) will govern the position limits for FLEX 
Equity Options. Pursuant to proposed Section 18(b)(1)(A), there will 
generally be no position limits for FLEX Equity Options with the 
exceptions noted below.\222\ Pursuant to proposed Section 18(b)(2), 
each Member (other than a Market Maker) that maintains a position on 
the same side of the market in excess of the standard limit under 
Options 9, Section 13 for non-FLEX Equity Options of the same class on 
behalf of its own account or for the account of a customer shall report 
information on the FLEX Equity option position, positions in any 
related instrument, the purpose or strategy for the position, and the 
collateral used by the account. This report shall be in the form and 
manner prescribed by the Exchange.\223\ Pursuant to proposed Section 
18(b)(3), whenever the Exchange determines that a higher margin 
requirement is necessary in light of the risks associated with a FLEX 
Equity option position in excess of the standard limit for non-FLEX 
Equity options of the same class, the Exchange may consider imposing 
additional margin upon the account maintaining such under-hedged 
position, pursuant to its authority under Options 6C, Section 5.\224\ 
Additionally, it should be noted that the clearing firm carrying the 
account will be subject to capital charges under Rule 15c3-1 under the 
Exchange Act to the extent of any margin deficiency resulting from the 
higher margin requirement.\225\
---------------------------------------------------------------------------

    \222\ See Cboe Rule 8.35(c)(1)(A) for materially identical 
provisions. Like Cboe, the Exchange's rule will have exceptions for 
the aggregation of FLEX positions (proposed Section 18(c)) and for 
position limits for cash-settled FLEX Equity Options where the 
underlying security is an ETF (proposed Section 18(b)(1)(B), which 
will be discussed later in this filing).
    \223\ See Cboe Rule 8.35(c)(2) for materially identical 
provisions.
    \224\ Options 6C, Section 5 provides that the amount of margin 
prescribed by these Rules is the minimum which must be required 
initially and subsequently maintained with respect to each account 
affected thereby; but nothing in these Rules shall be construed to 
prevent a Member from requiring margin in an amount greater than 
that specified. Further, the Exchange may at any time impose higher 
margin requirements with respect to such positions when it deems 
such higher margin requirements to be advisable.
    \225\ See Cboe Rule 8.35(c)(3) for materially identical 
provisions.
---------------------------------------------------------------------------

    Proposed Section 18(c) will govern the aggregation of FLEX 
positions. Specifically, for purposes of the position limits and 
reporting requirements set forth in this Section 18, FLEX Option 
positions shall not be aggregated with positions in non-FLEX Options 
other than as provided in this Section 18(c) and in Section 
18(b)(1)(B),\226\ and positions in FLEX Index Options on a given index 
shall not be aggregated with options on any stocks included in the 
index or with FLEX Index Option positions on another index.\227\ 
Pursuant to proposed Section 18(c)(1), commencing at the close of 
trading two business days prior to the last trading day of the calendar 
quarter, positions in P.M.-settled FLEX Index Options (i.e., FLEX Index 
Options having an exercise settlement value determined by the level of 
the index at the close of trading on the last trading day before 
expiration) shall be aggregated with positions in Quarterly Options 
Series on the same index with the same expiration and shall be subject 
to the position limits set forth in Options 4A, Section 6 or Section 7, 
as applicable.\228\ Pursuant to proposed Section 18(c)(2), commencing 
at the close of trading two business days prior to the last trading day 
of the week, positions in FLEX Index Options that are cash settled 
\229\ shall be aggregated with positions in Short Term Option Series on 
the same underlying (e.g., same underlying index as a FLEX Index 
Option) with the same means for determining exercise settlement value 
(e.g., opening or closing prices of the underlying index) and same 
expiration, and shall be subject to the position limits set forth in 
Options 4A, Section 6 (for broad-based index options) or Section 7 (for 
narrow-based index options), as applicable.\230\ Pursuant to proposed 
Section 18(c)(3), as long as the options positions remain open, 
positions in FLEX Options that expire on a third Friday-of-the-month 
expiration day shall be aggregated with positions in non-FLEX Options 
on the same underlying, and shall be subject to the position limits set 
forth in Options 4A, Section 6, Options 4A, Section 7, or Options 9, 
Section 13, as applicable, and the exercise limits set forth in Options 
9, Section 15, as applicable.\231\
---------------------------------------------------------------------------

    \226\ Proposed Section 18(b)(1)(B) will set forth the position 
limits for cash-settled FLEX ETF options and will be discussed later 
in this filing.
    \227\ See Cboe Rule 8.35(d) for materially identical provisions.
    \228\ See Cboe Rule 8.35(d)(1) for materially identical 
provisions.
    \229\ The Exchange notes that all FLEX Index Options will be 
cash settled.
    \230\ This is based on Cboe Rule 8.35(d)(2), except the Exchange 
does not currently list Credit Default Options and will therefore 
not incorporate the applicable portion into its proposed rule.
    \231\ See Cboe Rule 8.35(d)(3) for materially identical 
provisions.
---------------------------------------------------------------------------

T. Exercise Limits (Section 19)

    The Exchange proposes to detail the exercise limits for FLEX 
Options in Options 3A, Section 19. As discussed below, proposed Section 
19 will be based on the FLEX Options exercise limit rules on Cboe and 
Phlx.
    Proposed Section 19(a) will provide that exercise limits for FLEX 
Options shall be equivalent to the FLEX position limits prescribed in 
proposed Section 18.\232\ There shall be no exercise limits for broad-
based FLEX Index Options (including reduced value option contracts) on 
broad-based index options listed in Options 4A, Section 6(a).\233\
---------------------------------------------------------------------------

    \232\ Proposed Section 19(a) is based on Cboe Rule 8.42(g) 
except the Exchange will not incorporate references to Cboe-specific 
products like Micro FLEX Index Options, FLEX Individual Stock or ETF 
Based Volatility Index Options. Similarly, the Exchange will replace 
the references to Cboe-specific broad-based index options like SPX, 
VIX, etc. with the broad-based index options in Options 4A, Section 
6(a), which are similar index products on ISE.
    \233\ As such the following broad-based index options listed in 
Options 4A, Section 6(a) will have no exercise limits for FLEX Index 
Options: options on the Nasdaq 100 Index, Mini Nasdaq 100 Index, 
Nations VolDex Index, Nasdaq 100 Reduced Value Index, and Nasdaq 
Micro Index Options.
---------------------------------------------------------------------------

    Proposed Section 19(a)(1) will require that the minimum value size 
for FLEX Equity Option exercises be 25 contracts or the remaining size 
of the position, whichever is less.\234\ Proposed Section 19(a)(2) will 
require that the minimum value size for FLEX Index Option exercises be 
$1 million Underlying Equivalent Value (as defined below) or the 
remaining Underlying Equivalent Value of the position, whichever is 
less.\235\ Proposed Section 19(a)(3) will stipulate that except as 
provided in

[[Page 95006]]

proposed Section 18(b)(1)(B) and Section 18(c) above,\236\ FLEX Options 
shall not be taken into account when calculating exercise limits for 
non-FLEX Option contracts.\237\ Lastly, proposed Section 19(a)(4) will 
set forth the definition of Underlying Equivalent Value as the 
aggregate value of a FLEX Index Option (index multiplier times the 
current index value) multiplied by the number of FLEX Index 
Options.\238\
---------------------------------------------------------------------------

    \234\ See Cboe Rule 8.42(g)(1) for materially identical 
provisions.
    \235\ See Cboe Rule 8.42(g)(2) for materially identical 
provisions.
    \236\ As described above, proposed Section 18(c) will govern the 
aggregation of FLEX positions generally, while proposed Section 
18(b)(1)(B) will govern the aggregation of cash-settled FLEX Equity 
Options specifically and that positions in such cash-settled FLEX 
Equity Options will be aggregated with positions in physically 
settled options on the same underlying ETF. Cash-settled FLEX Equity 
Options will be discussed later in this filing.
    \237\ See Cboe Rule 8.42(g)(3) for materially identical 
provisions.
    \238\ See Phlx Options 8, Section 34(b)(8)(D) for materially 
identical provisions.
---------------------------------------------------------------------------

U. Capacity and Surveillances

    The Exchange has analyzed its capacity and represents that it 
believes the Exchange and the Options Price Reporting Authority 
(``OPRA'') have the necessary systems capacity to handle the additional 
message traffic associated with the listing of new series that may 
result from the introduction of FLEX Options.\239\
---------------------------------------------------------------------------

    \239\ The Exchange will report FLEX Option trades and, if 
necessary, trade cancellations to OPRA.
---------------------------------------------------------------------------

    Additionally, the Exchange believes it has an adequate surveillance 
program in place and intends to apply the same program procedures to 
FLEX Options that is applied to the Exchange's other options products, 
as applicable. FLEX Option products and their respective symbols will 
be integrated into the Exchange's existing surveillance system 
architecture and will be subject to the relevant surveillance 
processes. The Exchange believes that any potential risk of 
manipulative activity is mitigated by these existing surveillance 
technologies, procedures, and reporting requirements, which allow the 
Exchange to properly identify disruptive and/or manipulative trading 
activity. Additionally, taking into consideration that FLEX Options 
have unique characteristics, the Exchange has reviewed its catalog of 
patterns and updated a number of patterns to include FLEX Options 
transactions for when they begin trading. The Exchange will 
periodically review its surveillance procedures and make any changes 
that the Exchange believes are necessary for FLEX trading.
    As discussed in more detail in the ``Cash-Settled FLEX ETFs'' 
section below, the Exchange is also a member of the Intermarket 
Surveillance Group (``ISG''),\240\ and works with other self-regulatory 
organizations and exchanges on intermarket surveillance related issues 
through its participation in the ISG. As discussed in the ``Cash-
Settled FLEX ETFs'' section below, the Exchange and all other ISG 
members can and do share information for regulatory purposes.
---------------------------------------------------------------------------

    \240\ ISG is an industry organization formed in 1983 to 
coordinate intermarket surveillance among the SROs by cooperatively 
sharing regulatory information pursuant to a written agreement 
between the parties. The goal of the ISG's information sharing is to 
coordinate regulatory efforts to address potential intermarket 
trading abuses and manipulations.
---------------------------------------------------------------------------

V. Cash-Settled FLEX ETFs

    The Exchange proposes to include rule text in proposed Options 3A, 
Section 3(c) and Section 18, each as discussed above, to allow for cash 
settlement of certain FLEX Equity Options. Generally, as discussed 
above, FLEX Equity Options will be settled by physical delivery of the 
underlying security,\241\ while all FLEX Index Options will be settled 
by delivery in cash.\242\ The Exchange proposes to allow FLEX Equity 
Options where the underlying security is an ETF to be settled by 
delivery in cash if the underlying security meets prescribed criteria. 
The Exchange notes that cash-settled FLEX ETF Options will be subject 
to the same trading rules and procedures described above that will 
govern the trading of other FLEX Options on the Exchange, with the 
exception of the rules to accommodate the cash-settlement feature 
proposed as follows. Today, NYSE American Rule 903G \243\ and Cboe Rule 
4.21(b)(5)(A) \244\ allow for cash-settled FLEX ETF Options as well. 
The Exchange's proposed rule changes for cash-settled ETF Options will 
be based on NYSE American Rule 903G and Cboe Rule 4.21(b)(5)(A).
---------------------------------------------------------------------------

    \241\ See proposed Options 3A, Section 3(c)(5)(A)(i).
    \242\ See proposed Options 3A, Section 3(c)(5)(B). As discussed 
below, cash settlement is also permitted in the OTC market. Trading 
in cash-settled FLEX ETF Options will not commence until the related 
reporting requirements are finalized.
    \243\ See Securities Exchange Act Release No. 88131 (February 5, 
2020), 85 FR 7806 (February 11, 2020) (SR-NYSEAmer-2019-38) (Notice 
of Filing of Amendment No. 1 and Order Granting Accelerated Approval 
of a Proposed Rule Change, as Modified by Amendment No. 1, To Allow 
Certain Flexible Equity Options To Be Cash Settled).
    \244\ Cboe also filed an immediately effective rule change to 
allow certain FLEX Options to be cash settled. See Securities 
Exchange Act Release No. 98044 (August 2, 2023), 88 FR 53548 (August 
8, 2023) (SR-Cboe-2023-036) (Notice of Filing and Immediate 
Effectiveness of a Proposed Rule Change To Allow Certain Flexible 
Exchange Equity Options To Be Cash Settled).
---------------------------------------------------------------------------

    To permit cash settlement of certain FLEX ETF Options, the Exchange 
proposes rule text in Section 3(c)(5)(A)(ii) to provide that the 
exercise settlement for a FLEX ETF Option may be by physical delivery 
of the underlying ETF or by delivery in cash if the underlying 
security, measured over a defined six-mont
