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

    The Exchange proposes to amend Exchange Rules 504, Trading Halts, 
and 521, Nullification and Adjustment of Options Transactions including 
Obvious Errors.
    The text of the proposed rule change is available on the Exchange's 
Web site at http://www.miaxoptions.com/rule-filings, at MIAX's 
principal office, 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
Background
    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 
Commission approved on July 6, 2017,\4\ and those that the other 
options exchanges intend to or have filed. Finally, the Exchange notes 
that options exchanges that offer complex orders on their options 
platforms either already have in place rules for handling the 
adjustment and nullification of erroneous complex order transactions in 
place or have filed proposals related to such rules, which proposals 
have recently been approved by the Commission or filed on an 
immediately effective basis.\5\

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

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 Rule 521, 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,

[[Page 37634]]

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 Interpretation and Policy .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 Rule 521 and the NBBO is 
unavailable or deemed unreliable pursuant to Rule 521(b). The Exchange 
and other options exchanges have selected CBOE Livevol, LLC 
(``Livevol'') as the TP Provider, as described below. As further 
described below, proposed Interpretation and Policy .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 Interpretation and Policy .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 request and not through a streaming data feed.\6\ 
This language also makes clear that the Exchange and all other options 
exchanges will use the same TP Provider.
---------------------------------------------------------------------------

    \6\ 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 Interpretation and Policy 
.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.\7\ 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. 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.
---------------------------------------------------------------------------

    \7\ 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'').
---------------------------------------------------------------------------

    As proposed, to the extent an Official \8\ 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.\9\ 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.\10\
---------------------------------------------------------------------------

    \8\ For purposes of the Rule, an Official is an Officer of the 
Exchange or such other employee designee of the Exchange that is 
trained in the application of Rule 521.
    \9\ See proposed paragraph (b) to Interpretation and Policy .04.
    \10\ 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

[[Page 37635]]

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.\11\
---------------------------------------------------------------------------

    \11\ 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 Interpretation and Policy 
.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 Rule 521(e)(4), the Exchange has not proposed a 
specific time by which the service must be available in order to be 
considered timely.\12\ 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.
---------------------------------------------------------------------------

    \12\ 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 Rule 521(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 Rule 521(e), 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 
Interpretation and Policy .04 to Rule 521 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 Interpretation .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.\13\
---------------------------------------------------------------------------

    \13\ See, e.g., MIAX Rule 526, 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 Rule 521 to state that the Exchange will 
rely on paragraph (b) and Interpretation and Policy .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

[[Page 37636]]

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.
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 Rule 
521(b)(2).
     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.
    [cir] 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.
    [cir] 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.
    [cir] 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 Rule 521(b)(2). 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 \14\
---------------------------------------------------------------------------

    \14\ 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'').\15\
---------------------------------------------------------------------------

    \15\ 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

[[Page 37637]]

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 Rule 521(b)(2).
     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.
    [cir] 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.
    [cir] 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.
    [cir] 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.
     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 Rules 504 and 521(f)
    Exchange Rules 504 and 521(f) describe the Exchange's authority to 
declare trading halts in one or more options traded on the Exchange. 
Currently, Rule 521(f) and Interpretation and Policy .04 to Rule 504 
both state that the Exchange shall nullify any transaction that occurs 
during a trading halt in the affected option on the Exchange or, with 
respect to equity options, during a trading halt on the primary listing 
market for the underlying security. The Exchange proposes to make clear 
with respect to equity options that it 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.\16\ The Exchange will announce the 
operative date in a Regulatory Alert made available to its Members.
---------------------------------------------------------------------------

    \16\ See supra, note 4.
---------------------------------------------------------------------------

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.\17\ Specifically, the 
proposal is consistent with Section 6(b)(5) of the Act \18\ 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.
---------------------------------------------------------------------------

    \17\ 15 U.S.C. 78f(b).
    \18\ 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 \19\ in that the proposed Rule will foster 
cooperation and coordination with persons engaged in regulating and 
facilitating transactions.
---------------------------------------------------------------------------

    \19\ Id.
---------------------------------------------------------------------------

    The Exchange again reiterates that it has retained the standard of 
the current rule for most reviews of options transactions pursuant to 
Rule 521, 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 \20\ 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 Rule 521. 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

[[Page 37638]]

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.
---------------------------------------------------------------------------

    \20\ Id.
---------------------------------------------------------------------------

    The Exchange also believes its proposal to adopt language in 
paragraph (d) of Interpretation and Policy .04 to Rule 521 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,\21\ and is consistent with Section 6(b)(5) of the 
Act \22\ in that the proposed Rule will foster cooperation and 
coordination with persons engaged in regulating and facilitating 
transactions.
---------------------------------------------------------------------------

    \21\ See supra, note 13.
    \22\ 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 \23\ 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 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 \24\ 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.

    \24\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    Finally, with respect to the proposed modification to the 
Exchange's trading halt rules, Rule 504 and Rule 521(f), the Exchange 
believes that this proposal is consistent with Section 6(b)(5) of the 
Act \25\ because such proposal clarifies the provision by 
distinguishing between a trading halt in an underlying security where 
the security has halted trading across the industry (i.e., a regulatory 
halt) 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 this distinction is already 
clear in the rules of certain other options exchanges, and thus, has 
been found to be consistent with the Act.\26\

    \26\ See, e.g., Interpretation and Policy .07 to CBOE Rule 6.3.

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

    The Exchange does not believe that the proposed rule change will 
impose any burden on competition that is not necessary or appropriate 
in furtherance of the purposes of the Act. The Exchange believes the 
entire proposal is consistent with Section 6(b)(8) of the Act \27\ 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.
---------------------------------------------------------------------------

    \27\ 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 of 
erroneous options transactions. The Exchange does not believe that the 
rules applicable to such process in [sic] 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.

Rule Change Received From Members, Participants, or Others

    Written comments were neither solicited nor 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 \28\ and Rule 19b-4(f)(6) \29\ 
thereunder.
---------------------------------------------------------------------------

    \28\ 15 U.S.C. 78s(b)(3)(A).
    \29\ 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

[[Page 37639]]

Commission takes such action, the Commission shall institute 
proceedings to determine whether the proposed rule should be approved 
or disapproved.
