I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    The Exchange proposes to amend Chapter V, Section 6 of the 
Exchange's Options Rules (the ``Rules''), entitled ``Nullification and 
Adjustment of Options Transactions including Obvious Errors.''
    While these amendments are effective upon filing, the Exchange has 
designated the proposed amendments to be operative on a date that is 
within ninety (90) days after the Commission approved a similar 
proposal filed by Bats BZX on July 6, 2017.
    The text of the proposed rule change is available on the Exchange's 
Web site at http://nasdaqbx.cchwallstreet.com/, at the principal office 
of the Exchange, and at the Commission's Public Reference Room.

II. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the Exchange included statements 
concerning the purpose of and basis for the proposed rule change and 
discussed any comments it received on the proposed rule change. The 
text of these statements may be examined at the places specified in 
Item IV below. The Exchange has prepared summaries, set forth in 
sections A, B, and C below, of the most significant aspects of such 
statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The Exchange and other options exchanges recently adopted a new, 
harmonized rule related to the adjustment and nullification of 
erroneous options transactions, including a specific provision related 
to coordination in connection with large-scale events involving 
erroneous options transactions.\3\ The Exchange believes that the 
changes the options exchanges implemented with the new, harmonized rule 
have led to increased transparency and finality with respect to the 
adjustment and nullification of erroneous options transactions. 
However, as part of the initial initiative, the Exchange and other 
options exchanges deferred a few specific matters for further 
discussion. Specifically, as described in the Initial Filing, the 
Exchange and all other options exchanges have been working to further 
improve the review of potentially erroneous transactions as well as 
their subsequent adjustment by creating an objective and universal way 
to determine Theoretical Price in the event a reliable NBBO is not 
available. Because this initiative required additional exchange and 
industry discussion as well as additional time for development and 
implementation, the Exchange and the other options exchanges determined 
to proceed with the Initial Filing and to undergo a secondary 
initiative to complete any additional improvements to the applicable 
rule. In this filing, the Exchange proposes to adopt procedures that 
will lead to a more objective and uniform way to determine Theoretical 
Price in the event a reliable NBBO is not available. In addition to 
this change, the Exchange has proposed two additional minor changes to 
its rules. The Exchange's proposal mirrors that of Bats BZX, which the 
Exchange [sic] approved on July 6, 2017,\4\ and those that the other 
options exchanges intend to file.

Filing'').

of filing of Bats BZX proposal).
---------------------------------------------------------------------------

Calculation of Theoretical Price Using a Third Party Provider
    Under the harmonized rule, when reviewing a transaction as 
potentially erroneous, the Exchange needs to first determine the 
``Theoretical Price'' of the option, i.e., the Exchange's estimate of 
the correct market price for the option. Pursuant to Chapter V, Section 
6 of the Rules, if the applicable option series is traded on at least 
one other options exchange, then the Theoretical Price of an option 
series is the last national best bid (``NBB'') just prior to the trade 
in question with respect to an erroneous sell transaction or the last 
national best offer (``NBO'') just prior to the trade in question with 
respect to an erroneous buy transaction unless one of the exceptions 
described below exists. Thus, whenever the Exchange has a reliable NBB 
or NBO, as applicable, just prior to the transaction, then the Exchange 
uses this NBB or NBO as the Theoretical Price.
    The Rule also contains various provisions governing specific 
situations where the NBB or NBO is not available or may not be 
reliable. Specifically, the Rule specifies situations in which there 
are no quotes or no valid quotes for comparison purposes, when the 
national best bid or offer (``NBBO'') is determined to be too wide to 
be reliable, and at the open of trading on each trading day. In each of 
these circumstances, in turn, because the NBB or NBO is not available 
or is deemed to be unreliable, the Exchange determines Theoretical 
Price. Under the current Rule, when determining Theoretical Price, 
Exchange personnel generally consult and refer to data such as the 
prices of related series, especially the closest strikes in the option 
in question. Exchange personnel may also take into account the price of 
the underlying security and the volatility characteristics of the 
option as well as historical pricing of the option and/or similar 
options. Although the Rule is administered by experienced personnel and 
the Exchange believes the process is currently appropriate, the 
Exchange recognizes that it is also subjective and could lead to 
disparate results for a transaction that spans multiple options 
exchanges.
    The Exchange proposes to adopt Commentary .04 to specify how the 
Exchange will determine Theoretical Price when required by sub-
paragraphs (b)(1)-(3) of the Rule (i.e., at the open, when there are no 
valid quotes or when there is a wide quote). In particular, the 
Exchange has been working with other options exchanges to identify and 
select a reliable third party vendor (``TP Provider'') that would 
provide Theoretical Price to the Exchange whenever one or more 
transactions is under review pursuant to Chapter V, Section 6 of the 
Rules and the NBBO is unavailable or deemed unreliable pursuant to 
Chapter V, Section 6(b) of the Rules. The Exchange and other options 
exchanges have selected CBOE Livevol, LLC (``Livevol'') as the TP 
Provider, as described below. As further described below, proposed 
Commentary .04 would codify the use of the TP Provider as well as 
limited exceptions where the Exchange would be able to deviate from the 
Theoretical Price given by the TP Provider.
    Pursuant to proposed Commentary .04, when the Exchange must 
determine Theoretical Price pursuant to the sub-paragraphs (b)(1)-(3) 
of the Rule, the Exchange will request Theoretical Price from the third 
party vendor to which the Exchange and all other options exchanges have 
subscribed. Thus, as set forth in this proposed language, Theoretical 
Price would be provided to the Exchange by the TP Provider on

[[Page 37912]]

request and not through a streaming data feed.\5\ This language also 
makes clear that the Exchange and all other options exchanges will use 
the same TP Provider.
---------------------------------------------------------------------------

    \5\ Though the Exchange and other options exchanges considered a 
streaming feed, it was determined that it would be more feasible to 
develop and implement an on demand service and that such a service 
would satisfy the goals of the initiative.
---------------------------------------------------------------------------

    As noted above, the proposed TP Provider selected by the Exchange 
and other options exchanges is Livevol. The Exchange proposes to codify 
this selection in proposed paragraph (d) to Commentary .04. As such, 
the Exchange would file a rule proposal and would provide notice to the 
options industry of any proposed change to the TP Provider.
    The Exchange and other options exchanges have selected Livevol as 
the proposed TP Provider after diligence into various alternatives. 
Livevol has, since 2009, been the options industry leader in providing 
equity and index options market data and analytics services.\6\ The 
Exchange believes that Livevol has established itself within the 
options industry as a trusted provider of such services and notes that 
it and all other options exchanges already subscribe to various Livevol 
services. In connection with this proposal, Livevol will develop a new 
tool based on its existing technology and services that will supply 
Theoretical Price to the Exchange and other options exchanges upon 
request. The Theoretical Price tool will leverage current market data 
and surrounding strikes to assist in a relative value pricing approach 
to generating a Theoretical Price. When relative value methods are 
incapable of generating a valid Theoretical Price, the Theoretical 
Price tool will utilize historical trade and quote data to calculate 
Theoretical Price.
---------------------------------------------------------------------------

    \6\ The Exchange notes that in 2015, Livevol was acquired by 
CBOE Holdings, Inc., the ultimate parent company of the Chicago 
Board Options Exchange (``CBOE'') and C2 Options Exchange (``C2'').
---------------------------------------------------------------------------

    Because the purpose of the proposal is to move away from a 
subjective determination by Exchange personnel when the NBBO is 
unavailable or unreliable, the Exchange intends to use the Theoretical 
Price provided by the TP Provider in all such circumstances. However, 
the Exchange believes it is necessary to retain the ability to contact 
the TP Provider if it believes that the Theoretical Price provided is 
fundamentally incorrect and to determine the Theoretical Price in the 
limited circumstance of a systems issue experienced by the TP Provider, 
as described below.
    As proposed, to the extent an Official \7\ of the Exchange believes 
that the Theoretical Price provided by the TP Provider is fundamentally 
incorrect and cannot be used consistent with the maintenance of a fair 
and orderly market, the Official shall contact the TP Provider to 
notify the TP Provider of the reason the Official believes such 
Theoretical Price is inaccurate and to request a review and correction 
of the calculated Theoretical Price. For example, if an Official 
received from the TP Provider a Theoretical Price of $80 in a series 
that the Official might expect to be instead in the range of $8 to $10 
because of a recent corporate action in the underlying, the Official 
would request that the TP Provider review and confirm its calculation 
and determine whether it had appropriately accounted for the corporate 
action. In order to ensure that other options exchanges that may 
potentially be relying on the same Theoretical Price that, in turn, the 
Official believes to be fundamentally incorrect, the Exchange also 
proposes to promptly provide notice to other options exchanges that the 
TP Provider has been contacted to review and correct the calculated 
Theoretical Price at issue and to include a brief explanation of the 
reason for the request.\8\ Although not directly addressed by the 
proposed Rule, the Exchange expects that all other options exchanges 
once in receipt of this notification would await the determination of 
the TP Provider and would use the corrected price as soon as it is 
available. The Exchange further notes that it expects the TP Provider 
to cooperate with, but to be independent of, the Exchange and other 
options exchanges.\9\
---------------------------------------------------------------------------

    \7\ For purposes of the Rule, an Official is an Exchange staff 
member or contract employee designated as such by the Chief 
Regulatory Officer. See BX Rules, Chapter V, Sec. 6(a)(3).
    \8\ See proposed paragraph (b) to Commentary .04.
    \9\ The Exchange expects any TP Provider selected by the 
Exchange and other options exchanges to act independently in its 
determination and calculation of Theoretical Price. With respect to 
Livevol specifically, the Exchange again notes that Livevol is a 
subsidiary of CBOE Holdings, Inc., which is also the ultimate parent 
company of multiple options exchanges. The Exchange expects Livevol 
to calculate Theoretical Price independent of its affiliated 
exchanges in the same way it will calculate Theoretical Price 
independent of non-affiliated exchanges.
---------------------------------------------------------------------------

    The Exchange believes that the proposed provision to allow an 
Official to contact the TP Provider if he or she believes the provided 
Theoretical Price is fundamentally incorrect is necessary, particularly 
because the Exchange and other options exchanges will be using the new 
process for the first time. Although the exchanges have conducted 
thorough diligence with respect to Livevol as the selected TP Provider 
and would do so with any potential replacement TP Provider, the 
Exchange is concerned that certain scenarios could arise where the 
Theoretical Price generated by the TP Provider does not take into 
account relevant factors and would result in an unfair result for 
market participants involved in a transaction. The Exchange notes that 
if such situations do indeed arise, to the extent practicable the 
Exchange will also work with the TP Provider and other options 
exchanges to improve the TP Provider's calculation of Theoretical Price 
in future situations. For instance, if the Exchange determines that a 
particular type of corporate action is not being appropriately captured 
by the TP Provider when such provider is generating Theoretical Price, 
while the Exchange believes that it needs the ability to request a 
review and correction of the Theoretical Price in connection with a 
specific review in order to provide a timely decision to market 
participants, the Exchange would share information regarding the 
specific situation with the TP Provider and other options exchanges in 
an effort to improve the Theoretical Price service for future use. The 
Exchange notes that it does not anticipate needing to rely on this 
provision frequently, if at all, but believes the provision is 
necessary nonetheless to best prepare for all potential circumstances. 
Further, the Theoretical Price used by the Exchange in connection with 
its rulings will always be that received from the TP Provider and the 
Exchange has not proposed the ability to deviate from such price.\10\
---------------------------------------------------------------------------

    \10\ To the extent the TP Provider has been contacted by an 
Official of the Exchange, reviews the Theoretical Price provided but 
disagrees that there has been any error, then the Exchange would be 
bound to use the Theoretical Price provided by the TP Provider.
---------------------------------------------------------------------------

    Pursuant to proposed paragraph (c) to Commentary .04, an Official 
of the Exchange may determine the Theoretical Price if the TP Provider 
has experienced a systems issue that has rendered its services 
unavailable to accurately calculate Theoretical Price and such issue 
cannot be corrected in a timely manner. The Exchange notes that it does 
not anticipate needing to rely on this provision frequently, if at all, 
but believes the provision is necessary nonetheless to best prepare for 
all potential circumstances. Further, consistent with existing text in 
Chapter V, Section 6(e)(4) of the Rules, the Exchange has not proposed 
a specific time by which the service must be available in order to be 
considered

[[Page 37913]]

timely.\11\ The Exchange expects that it would await the TP Provider's 
services becoming available again so long as the Exchange was able to 
obtain information regarding the issue and the TP Provider had a 
reasonable expectation of being able to resume normal operations within 
the next several hours based on communications with the TP Provider. 
More specifically with respect to Livevol, Livevol has business 
continuity and disaster recovery procedures that will help to ensure 
that the Theoretical Price tool remains available or, in the event of 
an outage, that service is restored in a timely manner.
---------------------------------------------------------------------------

    \11\ In the context of a Significant Market Event, the Exchange 
may determine, ``in consultation with other options exchanges . . . 
that timely adjustment is not feasible due to the extraordinary 
nature of the situation.'' See BX Rules, Chapter V, Sec. 6(e)(4).
---------------------------------------------------------------------------

    The Exchange also notes that if a wide-scale event occurred, even 
if such event did not qualify as a ``Significant Market Event'' 
pursuant to Chapter V, Section 6(e) of the Rules, and the TP Provider 
was unavailable or otherwise experiencing difficulty, the Exchange 
believes that it and other options exchanges would seek to coordinate 
to the extent possible. In particular, the Exchange and other options 
exchanges now have a process, administered by the Options Clearing 
Corporation, to invoke a discussion amongst all options exchanges in 
the event of any widespread or significant market events. The Exchange 
believes that this process could be used in the event necessary if 
there were an issue with the TP Provider.
    The Exchange also proposes to adopt language in paragraph (d) of 
Commentary .04 to Chapter V, Section 6 of the Rules to disclaim the 
liability of the Exchange and the TP Provider in connection with the 
proposed Rule, the TP Provider's calculation of Theoretical Price, and 
the Exchange's use of such Theoretical Price. Specifically, the 
proposed rule would state that neither the Exchange, the TP Provider, 
nor any affiliate of the TP Provider (the TP Provider and its 
affiliates are referred to collectively as the ``TP Provider''), makes 
any warranty, express or implied, as to the results to be obtained by 
any person or entity from the use of the TP Provider pursuant to 
Commentary .04. The proposed rule would further state that the TP 
Provider does not guarantee the accuracy or completeness of the 
calculated Theoretical Price and that the TP Provider disclaims all 
warranties of merchantability or fitness for a particular purpose or 
use with respect to such Theoretical Price. Finally, the proposed Rule 
would state that neither the Exchange nor the TP Provider shall have 
any liability for any damages, claims, losses (including any indirect 
or consequential losses), expenses, or delays, whether direct or 
indirect, foreseen or unforeseen, suffered by any person arising out of 
any circumstance or occurrence relating to the use of such Theoretical 
Price or arising out of any errors or delays in calculating such 
Theoretical Price. This proposed language is modeled after existing 
language in Exchange Rules regarding ``reporting authorities'' that 
calculate indices.\12\
---------------------------------------------------------------------------

    \12\ See, e.g., BX Rules, Chapter XIV, Sec. 13, which relates to 
index options potentially listed and traded on the Exchange and 
disclaims liability for a reporting authority and their affiliates.
---------------------------------------------------------------------------

    In connection with the proposed change described above, the 
Exchange proposes to modify Chapter V, Section 6 of the Rules to state 
that the Exchange will rely on paragraph (b) and Commentary .04 when 
determining Theoretical Price.
No Valid Quotes--Market Participant Quoting on Multiple Exchanges
    As described above, one of the times where the NBB or NBO is deemed 
to be unreliable for purposes of Theoretical Price is when there are no 
quotes or no valid quotes for the affected series. In addition to when 
there are no quotes, the Exchange does not consider the following to be 
valid quotes: (i) All quotes in the applicable option series published 
at a time where the last NBB is higher than the last NBO in such series 
(a ``crossed market''); (ii) quotes published by the Exchange that were 
submitted by either party to the transaction in question; and (iii) 
quotes published by another options exchange against which the Exchange 
has declared self-help. In recognition of today's market structure 
where certain participants actively provide liquidity on multiple 
exchanges simultaneously, the Exchange proposes to add an additional 
category of invalid quotes. Specifically, in order to avoid a situation 
where a market participant has established the market at an erroneous 
price on multiple exchanges, the Exchange proposes to consider as 
invalid the quotes in a series published by another options exchange if 
either party to the transaction in question submitted the quotes in the 
series representing such options exchange's best bid or offer. Thus, 
similar to being able to ignore for purposes of the Rule the quotes 
published by the Exchange if submitted by either party to the 
transaction in question, the Exchange would be able to ignore for 
purposes of the rule quotations on other options exchanges by that same 
market participant.
    In order to continue to apply the Rule in a timely and organized 
fashion, however, the Exchange proposes to initially limit the scope of 
this proposed provision in two ways. First, because the process will 
take considerable coordination with other options exchanges to confirm 
that the quotations in question on an away options exchange were indeed 
submitted by a party to a transaction on the Exchange, the Exchange 
proposes to limit this provision to apply to up to twenty-five (25) 
total options series (i.e., whether such series all relate to the same 
underlying security or multiple underlying securities). Second, the 
Exchange proposes to require the party that believes it established the 
best bid or offer on one or more other options exchanges to identify to 
the Exchange the quotes which were submitted by such party and 
published by other options exchanges. In other words, as proposed, the 
burden will be on the party seeking that the Exchange disregard their 
quotations on other options exchanges to identify such quotations. In 
turn, the Exchange will verify with such other options exchanges that 
such quotations were indeed submitted by such party.
    Below are examples of both the current rule and the rule as 
proposed to be amended.
Example 1--Current Rule, Member Erroneously Quotes on One Exchange
Assumptions
    For purposes of this example, assume the following:
     A Member acting as a Market Maker on the Exchange 
(``Market Maker A'') is quoting in twenty series of options underlying 
security ABCD on the Exchange (and only the Exchange).
     Market Maker A makes an error in calculating the market 
for options on ABCD, and publishes quotes in all twenty series to buy 
options at $1.00 and to sell options at $1.05.
     In fact, options on ABCD in these series are nearly 
worthless and no other market participant is quoting in such series.
     Therefore, the NBBO in the twenty series at issue is $1.00 
x $1.05 (with the Exchange representing the NBBO based on Market Maker 
A's quotes).
     Assume Member A immediately enters sell orders and 
executes against Market Maker A's quotes at $1.00.
     Assume Market Maker A submits to the Exchange a timely 
request for review of the trades with Member A as potentially erroneous 
transactions to buy.

[[Page 37914]]

Result
     Based on the Exchange's current rules, the Exchange would 
identify Market Maker A as a participant to the trades at issue and 
would consider Market Maker A's quotations invalid pursuant to Chapter 
V, Section 6(b)(2) of the Rules.
     As there were no other valid quotes to use as a reference 
price, the Exchange would then determine Theoretical Price.
     Assume the Exchange determines a Theoretical Price of 
$0.05.
     The execution price of $1.00 exceeds the $0.25 minimum 
amount set forth in the Exchange's table to determine whether an 
obvious error has occurred (i.e., $0.05 + $0.25 = $0.30) so any 
execution at or above this price is an obvious error.
     Accordingly, the executions in all series would be 
adjusted by the Exchange to executions at $0.20 per contract 
(Theoretical Price of $0.05 plus $0.15) to the extent the incoming 
orders submitted by Member A were non-Customer orders.
     The executions in all series would be nullified to the 
extent the incoming orders submitted by Member A were Customer orders.
Example 2--Current Rule, Member Erroneously Quotes on Multiple 
Exchanges
Assumptions
    For purposes of this example, assume the following:
     A Member acting as a Market Maker on the Exchange 
(``Market Maker A'') is quoting in twenty series of options underlying 
security ABCD on the Exchange and on a second exchange (``Away 
Exchange'').
     Market Maker A makes an error in calculating the market 
for options on ABCD, and publishes quotes on both the Exchange and the 
Away Exchange in all twenty series to buy options at $1.00 and to sell 
options at $1.05.
     In fact, options on ABCD in these series are nearly 
worthless and no other market participant is quoting in such series.
     Therefore, the NBBO in the twenty series at issue is $1.00 
x $1.05 (with the Exchange and the Away Exchange representing the NBBO 
based on Market Maker A's quotes).
     Assume Member A immediately enters sell orders and 
executes against Market Maker A's quotes at $1.00.
     Assume Market Maker A submits to the Exchange and to the 
Away Exchange timely requests for review of the trades with Member A as 
potentially erroneous transactions to buy.
Result
     Based on the Exchange's current rules, the Exchange would 
identify Market Maker A as a participant to the trades at issue and 
would consider Market Maker A's quotations on the Exchange invalid 
pursuant to Chapter V, Section 6(b)(2) of the Rules. The Exchange, 
however, would view the Away Exchange's quotations as valid, and would 
thus determine Theoretical Price to be $1.05 (i.e., the NBO in the case 
of a potentially erroneous buy transaction).
     The execution price of $1.00 does not exceed the $0.25 
minimum amount set forth in the Exchange's table to determine whether 
an obvious error has occurred (i.e., $1.05 + $0.25 = $1.30) so any 
execution at or above this price is an obvious error.
     The transactions on the Exchange would not be nullified or 
adjusted.
     As the Exchange and all other options exchanges have 
identical rules with respect to the process described above, the 
transactions on the Away Exchange would not be nullified or adjusted.
Example 3--Proposed Rule, Member Erroneously Quotes on Multiple 
Exchanges \13\
---------------------------------------------------------------------------

    \13\ The Exchange notes that its proposed rule will not impact 
the proposed handling of a request for review where a market 
participant is quoting only on the Exchange, thus, the Exchange has 
not included a separate example for such a fact pattern.
---------------------------------------------------------------------------

Assumptions
    For purposes of this example, assume the following:
     A Member acting as a Market Maker on the Exchange 
(``Market Maker A'') is quoting in twenty series of options underlying 
security ABCD on the Exchange and on a second exchange (``Away 
Exchange'').\14\
---------------------------------------------------------------------------

    \14\ The Exchange notes that the proposed rule would operate the 
same if Market Maker A was quoting on more than two exchanges. The 
Exchange has limited the example to two exchanges for simplicity.
---------------------------------------------------------------------------

     Market Maker A makes an error in calculating the market 
for options on ABCD, and publishes quotes on both the Exchange and the 
Away Exchange in all twenty series to buy options at $1.00 and to sell 
options at $1.05.
     In fact, options on ABCD in these series are nearly 
worthless and no other market participant is quoting in such series.
     Therefore, the NBBO in the twenty series at issue is $1.00 
x $1.05 (with the Exchange and the Away Exchange representing the NBBO 
based on Market Maker A's quotes).
     Assume Member A immediately enters sell orders and 
executes against Market Maker A's quotes at $1.00.
     Assume Market Maker A submits to the Exchange and to the 
Away Exchange timely requests for review of the trades with Member A as 
potentially erroneous transactions to buy. At the time of submitting 
the requests for review to the Exchange and the Away Exchange, Market 
Maker A identifies to the Exchange the quotes on the Away Exchange as 
quotes also represented by Market Maker A (and to the Away Exchange, 
the quotes on the Exchange as quotes also represented by Market Maker 
A).
Result
     Based on the proposed rules, the Exchange would identify 
Market Maker A as a participant to the trades at issue and would 
consider Market Maker A's quotations on the Exchange invalid pursuant 
to Chapter V, Section 6(b)(2) of the Rules.
     The Exchange and the Away Exchange would also coordinate 
to confirm that the quotations identified by Market Maker A on the 
other exchange were indeed Market Maker A's quotations. Once confirmed, 
each of the Exchange and the Away Exchange would also consider invalid 
the quotations published on the other exchange.
     As there were no other valid quotes to use as a reference 
price, the Exchange would then determine Theoretical Price.
     Assume the Exchange determines a Theoretical Price of 
$0.05.
     The execution price of $1.00 exceeds the $0.25 minimum 
amount set forth in the Exchange's table to determine whether an 
obvious error has occurred (i.e., $0.05 + $0.25 = $0.30) so any 
execution at or above this price is an obvious error.
     Accordingly, the executions in all series would be 
adjusted by the Exchange to executions at $0.20 per contract 
(Theoretical Price of $0.05 plus $0.15) to the extent the incoming 
orders submitted by Member A were non-Customer orders.
     The executions in all series would be nullified to the 
extent the incoming orders submitted by Member A were Customer orders.
     As the Exchange and all other options exchanges would have 
identical rules with respect to the process described above, as other 
options exchanges intend to adopt the same rule if the proposed rule is 
approved, the transactions on the Away Exchange would also be nullified 
or adjusted as set forth above.

[[Page 37915]]

     If this example was instead modified such that Market 
Maker A was quoting in 200 series rather than 20, the Exchange notes 
that Market Maker A could only request that the Exchange consider as 
invalid their quotations in 25 of those series on other exchanges. As 
noted above, the Exchange has proposed to limit the proposed rule to 25 
series in order to continue to process requests for review in a timely 
and organized fashion in order to provide certainty to market 
participants. This is due to the amount of coordination that will be 
necessary in such a scenario to confirm that the quotations in question 
on an away options exchange were indeed submitted by a party to a 
transaction on the Exchange.
Trading Halts--Clarifying Change to Chapter V, Section 6
    Commentary .03 to Chapter V, Section 6 of the Rules describes the 
Exchange's authority to declare trading halts in one or more options 
traded on the Exchange. The Exchange proposes to modify this provision 
to provide that, with respect to equity options, the Exchange shall 
nullify any transaction that occurs during a regulatory halt as 
declared by the primary listing market for the underlying security. The 
Exchange believes this change is necessary to distinguish a declared 
regulatory halt, where the underlying security should not be actively 
trading on any venue, from an operational issue on the primary listing 
exchange where the security continues to safely trade on other trading 
venues.
Implementation Date
    The Exchange proposes to delay the operative date of this proposal 
to a date within ninety (90) days after the Commission approved the 
Bats BZX proposal on July 6, 2017. The Exchange will announce the 
operative date in a Regulatory Alert made available to its Members.
2. Statutory Basis
    The Exchange believes that its proposal is consistent with the 
requirements of the Act and the rules and regulations thereunder that 
are applicable to a national securities exchange, and, in particular, 
with the requirements of Section 6(b) of the Act.\15\
---------------------------------------------------------------------------

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

    Specifically, the proposal is consistent with Section 6(b)(5) of 
the Act \16\ because it would promote just and equitable principles of 
trade, remove impediments to, and perfect the mechanism of, a free and 
open market and a national market system, and, in general, protect 
investors and the public interest.
---------------------------------------------------------------------------

    \16\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    As described above, the Exchange and other options exchanges are 
seeking to further modify their harmonized rules related to the 
adjustment and nullification of erroneous options transactions. The 
Exchange believes that the proposal to utilize a TP Provider in the 
event the NBBO is unavailable or unreliable will provide greater 
transparency and clarity with respect to the adjustment and 
nullification of erroneous options transactions. Particularly, the 
proposed changes seek to achieve consistent results for participants 
across U.S. options exchanges while maintaining a fair and orderly 
market, protecting investors and protecting the public interest. Thus, 
the Exchange believes that the proposal is consistent with Section 
6(b)(5) of the Act \17\ in that the proposed Rule will foster 
cooperation and coordination with persons engaged in regulating and 
facilitating transactions.

    The Exchange again reiterates that it has retained the standard of 
the current rule for most reviews of options transactions pursuant to 
Chapter V, Section 6 of the Rules, which is to rely on the NBBO to 
determine Theoretical Price if such NBBO can reasonably be relied upon. 
The proposal to use a TP Provider when the NBBO is unavailable or 
unreliable is consistent with Section 6(b)(5) of the Act \18\ in that 
the proposed Rule will foster cooperation and coordination with persons 
engaged in regulating and facilitating transactions by further reducing 
the possibility of disparate results between options exchanges and 
increasing the objectivity of the application of Chapter V, Section 6 
of the Rules. Further, the Exchange believes that the proposed Rule is 
transparent with respect to the limited circumstances under which the 
Exchange will request a review and correction of Theoretical Price from 
the TP Provider, and has sought to limit such circumstances as much as 
possible. The Exchange notes that under the current Rule, Exchange 
personnel are required to determine Theoretical Price in certain 
circumstances and yet rarely do so because such circumstances have 
already been significantly limited under the harmonized rule (for 
example, because the wide quote provision of the harmonized rule only 
applies if the quote was narrower and then gapped but does not apply if 
the quote had been persistently wide). Thus, the Exchange believes it 
will need to request Theoretical Price from the TP Provider only in 
very rare circumstances and in turn, the Exchange anticipates that the 
need to contact the TP Provider for additional review of the 
Theoretical Price provided by the TP Provider will be even rarer. 
Similarly, the Exchange believes it is unlikely that an Exchange 
Official will ever be required to determine Theoretical Price, as such 
circumstance would only be in the event of a systems issue that has 
rendered the TP Provider's services unavailable and such issue cannot 
be corrected in a timely manner.
---------------------------------------------------------------------------

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

    The Exchange also believes its proposal to adopt language in 
paragraph (d) of Commentary .04 to Chapter V, Section 6 of the Rules to 
disclaim the liability of the Exchange and the TP Provider in 
connection with the proposed Rule, the TP Provider's calculation of 
Theoretical Price, and the Exchange's use of such Theoretical Price is 
consistent with the Act. As noted above, this proposed language is 
modeled after existing language in Exchange Rules regarding ``reporting 
authorities'' that calculate indices,\19\ and is consistent with 
Section 6(b)(5) of the Act \20\ in that the proposed Rule will foster 
cooperation and coordination with persons engaged in regulating and 
facilitating transactions.
---------------------------------------------------------------------------

    \19\ See supra, note 12.
    \20\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    As described above, the Exchange proposes a modification to the 
valid quotes provision to also exclude quotes in a series published by 
another options exchange if either party to the transaction in question 
submitted the orders or quotes in the series representing such options 
exchange's best bid or offer. The Exchange believes this proposal is 
consistent with Section 6(b)(5) of the Act \21\ because the application 
of the rule will foster cooperation and coordination with persons 
engaged in regulating and facilitating transactions by allowing the 
Exchange to coordinate with other options exchanges to determine 
whether a market participant that is party to a potentially erroneous 
transaction on the Exchange established the market in an option on 
other options exchanges; to the extent this can be established, the 
Exchange believes such participant's quotes should be excluded in the 
same way such quotes are excluded on the Exchange. The Exchange also 
believes it is reasonable to limit the scope of this provision to 
twenty-five (25) series and to require the party that believes it 
established the best bid or offer on one

[[Page 37916]]

or more other options exchanges to identify to the Exchange the quotes 
which were submitted by that party and published by other options 
exchanges. The Exchange believes these limitations are consistent with 
Section 6(b)(5) of the Act \22\ because they will ensure that the 
Exchange is able to continue to apply the Rule in a timely and 
organized fashion, thus fostering cooperation and coordination with 
persons engaged in regulating and facilitating transactions and also 
removing impediments to and perfecting the mechanism of a free and open 
market and a national market system.

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

    Finally, with respect to the proposed modification to Commentary 
.03 to Chapter V, Section 6, the Exchange believes that this proposal 
is consistent with Section 6(b)(5) of the Act \23\ because it 
specifically provides for nullification where a trading halt exists 
with respect to an underlying security across the industry (i.e., a 
regulatory halt) as distinguished from a situation where the primary 
exchange has experienced a technical issue but the underlying security 
continues to trade on other equities platforms. The Exchange notes that 
a similar provision already exists in the rules of certain other 
options exchanges, and thus, has been found to be consistent with the 
Act.

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

    The Exchange believes the entire proposal is consistent with 
Section 6(b)(8) of the Act \24\ in that it does not impose any burden 
on competition that is not necessary or appropriate in furtherance of 
the purposes of the Act as explained below.
---------------------------------------------------------------------------

    \24\ 15 U.S.C. 78f(b)(8).
---------------------------------------------------------------------------

    Importantly, the Exchange does not believe that the proposal will 
impose a burden on intermarket competition but rather that it will 
alleviate any burden on competition because it is the result of a 
collaborative effort by all options exchanges to further harmonize and 
improve the process related to the adjustment and nullification o [sic] 
erroneous options transactions. The Exchange does not believe that the 
rules applicable to such process is an area where options exchanges 
should compete, but rather, that all options exchanges should have 
consistent rules to the extent possible. Particularly where a market 
participant trades on several different exchanges and an erroneous 
trade may occur on multiple markets nearly simultaneously, the Exchange 
believes that a participant should have a consistent experience with 
respect to the nullification or adjustment of transactions. To that 
end, the selection and implementation of a TP Provider utilized by all 
options exchanges will further reduce the possibility that participants 
with potentially erroneous transactions that span multiple options 
exchanges are handled differently on such exchanges. Similarly, the 
proposed ability to consider quotations invalid on another options 
exchange if ultimately originating from a party to a potentially 
erroneous transaction on the Exchange represents a proposal intended to 
further foster cooperation by the options exchanges with respect to 
market events. The Exchange understands that all other options 
exchanges either have or they intend to file proposals that are 
substantially similar to this proposal.
    The Exchange does not believe that the proposed rule change imposes 
a burden on intramarket competition because the proposed provisions 
apply to all market participants equally.

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

    No written comments were either solicited or received.

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

    Because the foregoing proposed rule change does not: (i) 
Significantly affect the protection of investors or the public 
interest; (ii) impose any significant burden on competition; and (iii) 
become operative for 30 days after the date of the filing, or such 
shorter time as the Commission may designate, it has become effective 
pursuant to 19(b)(3)(A) of the Act \25\ and Rule 19b-4(f)(6) \26\ 
thereunder.
---------------------------------------------------------------------------

    \25\ 15 U.S.C. 78s(b)(3)(A).
    \26\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6) 
requires a self-regulatory organization to give the Commission 
written notice of its intent to file the proposed rule change, along 
with a brief description and text of the proposed rule change, at 
least five business days prior to the date of filing of the proposed 
rule change, or such shorter time as designated by the Commission. 
The Exchange has satisfied this requirement.
---------------------------------------------------------------------------

    At any time within 60 days of the filing of the proposed rule 
change, the Commission summarily may temporarily suspend such rule 
change if it appears to the Commission that such action is necessary or 
appropriate in the public interest, for the protection of investors, or 
otherwise in furtherance of the purposes of the Act. If the Commission 
takes such action, the Commission shall institute proceedings to 
determine whether the proposed rule should be approved or disapproved.
