    \6\ In Amendment No. 1, the Exchange further responds to 
comments, clarifies the way the proposed rule would work in 
practice, and proposes to revise the rule text. The proposed 
revisions submitted in Amendment No. 1 include a provision stating 
that SAL would not allow market maker quotes comprising the National 
Best Bid or Offer (``NBBO'') to be cancelled during an auction, 
provisions describing how orders would be executed in the event a 
SAL auction terminates early because of a quote lock or a response 
that matches the Exchange's disseminated quote on the opposite side 
of the market from the response, and several other minor 
clarifications of the proposed rule text.
    \7\ In Amendment No. 2, the Exchange proposes amendments to the 
rule text to clarify that the Exchange will submit eligible orders 
for SAL auctioning and automatically execute eligible orders even if 
the Exchange's disseminated market is crossed by, or crosses, the 
disseminated market of another options exchange, provided that the 
Exchange is at the NBBO for the relevant side of the market.
    \8\ In Amendment No. 3, the Exchange proposes an amendment to 
the text of its order protection rule to add an exception to trade-
through liability in the case of a trade-through that results from 
an automatic execution when the Exchange's disseminated market is 
the NBBO and is crossed by, or crosses, the disseminated market of 
another options exchange. See infra Part II for a complete 
discussion of the proposed rule change, as amended.
---------------------------------------------------------------------------

II. Description of the Proposed Rule Change

    The Exchange proposes to amend its rules to implement SAL, a penny 
auction system for price improvement over the NBBO for eligible inbound 
orders, and to clarify the Exchange's policy of automatically executing 
eligible orders in a crossed market when the Exchange is at the NBBO.
    SAL would automatically initiate an auction process for any order 
that is eligible for automatic execution by the Hybrid System (``Agency 
Order''), unless the Exchange's disseminated quotation on the opposite 
side of the market from the Agency Order does not contain sufficient 
quotation size from CBOE Market-Makers to satisfy the entire Agency 
Order. SAL would stop the Agency Order at the NBBO against the market 
maker quotations displayed at the NBBO and would not allow such 
quotations to be cancelled or to move to an inferior price or size 
throughout the duration of the auction. The Agency Order would not be 
stopped against customer orders that are displayed at the NBBO because 
the Exchange does not have the ability to prevent a customer order from 
being cancelled or changed to an inferior price or size.
    The auction would last for a period of time to be determined by the 
Exchange, but would not exceed two seconds. Auction responses would be 
permitted to be submitted by market makers with an appointment in the 
relevant option class and by CBOE Members acting as agent for orders 
resting at the top of the Exchange's book opposite the Agency Order. 
With respect to responses, the following would apply: (i) Responses 
would not be visible to other auction participants and would not be 
disseminated to the Options Price Reporting Authority (``OPRA''); (ii) 
responses would be submitted in one-cent increments (and not less than 
one-cent increments); (iii) multiple responses would be allowed; (iv) 
responses would be permitted to be cancelled prior to the conclusion of 
the auction; and (v) responses would not be permitted to cross the 
Exchange's disseminated quotation on the opposite side of the market.
    At the conclusion of the auction period, the Agency Order would be 
executed at the best auction response prices and could be executed at 
multiple prices, if necessary. The Agency Order would be allocated in 
two rounds at each price point. Participation in the first round (the 
``First Allocation Round'') would be limited to those parties that 
constituted the Exchange's NBBO quote (on the side of the market 
opposite the Agency Order) at the time the SAL auction commenced 
(``Original Quoters''). During the First Allocation Round: (i) The 
Agency Order would be allocated pursuant to the matching algorithm in 
effect for the class under CBOE Rules 6.45A or 6.45B, as appropriate; 
(ii) an Original Quoter would be permitted to participate in a

[[Page 44059]]

First Allocation Round at each allocation price only up to its size at 
the NBBO at the time the auction commenced; and (iii) if the applicable 
matching algorithm includes a participation entitlement, then market 
makers that would have qualified for a participation entitlement at the 
NBBO price would receive a participation entitlement in a First 
Allocation Round if they match the execution price for that round.
    If an Agency Order were not fully executed during the First 
Allocation Round, then a second round (``Second Allocation Round'') 
would occur at the same price point. During the Second Allocation 
Round, there is no participation right, and all responses received 
during the auction at the execution price of the immediately preceding 
First Allocation Round that were not eligible for that preceding round 
would participate in accordance with the matching algorithm in effect 
for the class. If the Agency Order were not fully allocated in the 
Second Allocation Round, then allocation of the Agency Order would 
proceed at the next best response price. To the extent that any portion 
of an Agency Order is executed at the NBBO price that was disseminated 
at the time the auction commenced, such execution will be effected 
against the participants at that NBBO price that were quoting at the 
time the auction commenced, using the matching algorithm in effect for 
the class, without regard as to whether any of those participants 
submitted responses in the auction.
    The auction would conclude early under certain circumstances:
     First, if the Hybrid System receives an unrelated non-
marketable limit order on the opposite side of the market from the 
Agency Order that improves any auction responses, the auction would 
conclude and the unrelated order would trade with the Agency Order 
(after any responses that were priced better than the unrelated order 
have traded) to the fullest extent possible at the midpoint of the best 
remaining auction response and the unrelated order's limit price 
(rounded towards the unrelated order's limit price when necessary).
     Second, if the Hybrid System receives an unrelated market 
or marketable limit order on the opposite side of the market from the 
Agency Order, the auction would conclude and the unrelated order would 
trade with the Agency Order to the fullest extent possible at the 
midpoint of the best auction response and the NBBO on the opposite side 
of the market from the auction responses (rounded towards the 
disseminated quote when necessary).
     Third, if the Hybrid System receives an unrelated order on 
the same side of the market as the Agency Order that is marketable 
against the NBBO, then the auction would conclude and the Agency Order 
would trade against the best auction responses.
     Fourth, any time there is a quote lock on the Exchange 
pursuant to CBOE Rule 6.45A(d) or CBOE Rule 6.45B(d), the auction would 
conclude. If the quote lock occurs at a price favorable to the Agency 
Order, then the Agency Order would trade against the quote lock 
interest to the fullest extent possible. If the quote lock is at a 
price that is inferior to the auction responses, then the Agency Order 
would trade against the best auction responses.\9\
---------------------------------------------------------------------------

    \9\ See Amendment No. 1, supra note 6.
---------------------------------------------------------------------------

     Fifth, any time a response matches the Exchange's 
disseminated quote on the opposite side of the market from the 
response, the auction would conclude. In this situation, if the 
disseminated quote on the opposite side of the market from the response 
does not contain a customer order, then the response would trade 
against the Agency Order. If it does contain a customer order, then, if 
there is sufficient size in the response to execute both orders, both 
orders would execute at that price. If not, then the Agency Order would 
execute against the response at one cent worse than the response price 
and any balance would trade against the customer order in the book at 
such order's limit price.\10\
---------------------------------------------------------------------------

    \10\ See id.
---------------------------------------------------------------------------

    The Exchange also proposes to adopt provisions providing that a 
pattern or practice of submitting unrelated orders that cause an 
auction to conclude early and disseminating information regarding 
auctioned orders to third parties would be deemed conduct inconsistent 
with just and equitable principles of trade and a violation of CBOE 
Rule 4.1 and other Exchange Rules.
    Finally, the Exchange proposes to adopt provisions that clarify 
that the Exchange's Hybrid System will automatically execute eligible 
orders while the Exchange's disseminated market is crossed with the 
disseminated market of another exchange, provided that the Exchange is 
the NBBO for the relevant side of the market at the time the eligible 
order is received.\11\ This situation might arise either with an 
automatic execution on Hybrid in connection with a SAL auction or with 
an automatic execution on Hybrid that is not eligible for SAL. A 
related proposed amendment to the Exchange's order protection rule adds 
an exception to trade-through liability in cases where the trade-
through was the result of an automatic execution when the Exchange's 
disseminated market is the NBBO and is crossed with the disseminated 
market of another exchange.\12\
---------------------------------------------------------------------------

    \11\ See Amendment No. 2, supra note 7.
    \12\ See Amendment No. 3, supra note 8.
---------------------------------------------------------------------------

    The text of the changes proposed in Amendments No. 1, 2, and 3 is 
available on CBOE's Web site (http://www.cboe.org/legal), at CBOE's 

office of the Secretary, and at the Commission's Public Reference Room.

III. Discussion and Commission Findings

    After careful review of the amended proposal and consideration of 
the comment letters and the Response Letter, the Commission finds that 
the proposed rule change, as amended, is consistent with the 
requirements of the Act and the rules and regulations thereunder 
applicable to a national securities exchange.\13\ In particular, the 
Commission finds that the proposed rule change is consistent with 
Section 6(b)(5) of the Act,\14\ which requires, among other things, 
that the rules of an exchange be designed to prevent fraudulent and 
manipulative acts and practices, to promote just and equitable 
principles of trade, to foster cooperation and coordination with 
persons engaged in regulating, clearing, settling, processing 
information with respect to, and facilitating transactions in 
securities, to remove impediments to and perfect the mechanism of a 
free and open market and a national market system, and, in general, to 
protect investors and the public interest. Section 6(b)(5) of the Act 
\15\ also requires that the rules the rules of an exchange not be 
designed to permit unfair discrimination among customers, issuers, 
brokers, or dealers.
---------------------------------------------------------------------------

    \13\ In approving this proposed rule change, the Commission has 
considered the proposed rule's impact on efficiency, competition, 
and capital formation. See 15 U.S.C. 78c(f).
    \14\ 15 U.S.C. 78f(b)(5).
    \15\ Id.
---------------------------------------------------------------------------

A. SAL Auctions

    The Commission believes that approving the Exchange's proposal to 
establish SAL auctions should confer benefits to the public by 
providing the Exchange's customers with the opportunity for price 
improvement over the NBBO for qualifying orders, which would result in 
better executions for investors. The Commission also believes that 
access to the SAL auction for those eligible market participants who 
wish to compete for an Agency Order should be sufficient to provide 
opportunities for

[[Page 44060]]

meaningful, competitive auctions, consistent with Section 3(f) of the 
Act.\16\ The Commission therefore finds, for the reasons discussed 
below, that the Exchange's proposal is consistent with the Act.
---------------------------------------------------------------------------

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

 1. Transparency of the Auction
    In its comment letter, Citadel argues that SAL would hinder price 
discovery because auction responses would not be disseminated to OPRA, 
and the true price and size of executions on CBOE would not be known to 
other market participants.\17\ In its Response Letter, CBOE states that 
the SAL auction is invisible to OPRA because OPRA does not accept penny 
quoting at this time, and the Exchange cannot disseminate quotations 
outside of OPRA that are superior to quotations provided to OPRA.\18\ 
In addition, CBOE states that responses to the SAL auction are blind in 
order to enhance price discovery. CBOE believes a blind auction will 
maximize the winning responses, providing greater price improvement for 
the Agency Order.\19\
---------------------------------------------------------------------------

    \17\ See Citadel Letter, supra note 4, at 2.
    \18\ See Response Letter, supra note 5, at 2.
    \19\ See id.
---------------------------------------------------------------------------

    The Commission notes that non-electronic auction responses in 
traditional open outcry floor auctions are not disseminated to OPRA by 
any market. The Commission has found these auctions consistent with the 
Act, notwithstanding that responses in open outcry are not disseminated 
to OPRA.\20\ The Commission believes that the SAL auction is analogous 
to the open outcry auctions currently conducted on floor-based 
exchanges, where auction prices are not widely disseminated and are 
available only for the order that initiated the auction and other 
orders in the crowd at that particular time. Accordingly, the 
Commission finds the SAL auction to be consistent with the Act.
---------------------------------------------------------------------------

    \20\ See CBOE Rule 6.74A(b)(1)(F); BOX Rules, Chapter V, Sec. 
18(j); and ISE Rule 723(c).
---------------------------------------------------------------------------

2. Eligibility of Orders for the Auction
    BOX and Citadel both argue that the Exchange would be granted too 
much discretion under the proposal.\21\ Citadel argues that SAL would 
permit discrimination because the Exchange could determine which 
categories of orders may be entered into the auction for potential 
price improvement. Specifically, CBOE's Floor Procedure Committee could 
choose not to permit the orders of certain types of market 
participants--i.e., public customer orders, non-market maker broker-
dealer orders, and market maker broker-dealer orders--from being 
eligible for a SAL auction.\22\
---------------------------------------------------------------------------

    \21\ See BOX Letter, supra note 4, at 2, and Citadel Letter, 
supra note 4, at 2.
    \22\ See Citadel Letter, supra note 4, at 2.
---------------------------------------------------------------------------

    In response, CBOE states that the options markets have a long 
history of providing enhanced executions to some categories of orders 
over others (e.g., public customer orders over broker-dealer orders and 
market maker orders), and that SAL simply provides this same 
flexibility to the Exchange.\23\ The Commission agrees that the options 
markets have, in certain circumstances, treated different categories of 
orders disparately, restricting, for example, the types of orders that 
may be executed via their automated facilities.\24\ The proposed rule 
change would, similarly, permit the Exchange's Floor Procedure 
Committee to determine the types of market participants that would be 
eligible to have their orders auctioned for price improvement. The 
proposal would not, however, permit the Committee to discriminate among 
individual market participants of the same type (e.g., permit certain 
public customer orders but not others to be eligible for the SAL 
auction). In addition, the proposal would not permit the Committee to 
limit those who may enter auction responses; auction responses may be 
submitted by market makers with an appointment in the relevant option 
class and members acting as agent for orders resting at the top of the 
Exchange's book.
---------------------------------------------------------------------------

    \23\ See Response Letter, supra note 5, at 2.
    \24\ See, e.g., American Stock Exchange LLC (``Amex'') Rule 
933(a) (stating only non broker-dealer customer orders shall be 
eligible for execution on Amex's Automatic Execution System, but 
that the Amex Floor Committee may allow broker-dealer orders on a 
case-by-case basis); and Philadelphia Stock Exchange (``Phlx'') Rule 
1080(b) and (c) (naming the types of orders eligible for entry into 
AUTOM and for automatic executions via AUTO-X; Phlx's Options 
Committee ``may determine to accept additional types of orders as 
well as to discontinue accepting certain types of orders'').
---------------------------------------------------------------------------

    The Act does not prohibit exchange rules from discriminating; it 
requires only that the rules of an exchange not be designed to unfairly 
discriminate.\25\ Therefore, the Commission finds that providing an 
Exchange committee with the discretion to determine the types of market 
participants provided the opportunity to have their orders 
automatically executed at a better price than the NBBO does not 
unfairly discriminate among market participants, and is consistent with 
the Act.
---------------------------------------------------------------------------

    \25\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    BOX commented that the SAL proposal fails to designate the orders 
that would be eligible to participate in the auction or to describe how 
CBOE plans to communicate the eligibility criteria to the public.\26\ 
In Amendment No. 1, CBOE clarifies that, prior to deploying SAL, it 
would announce via a regulatory circular all applicable parameters 
relating to order eligibility and auction duration.\27\
---------------------------------------------------------------------------

    \26\ See BOX Letter, supra note 4, at 2.
    \27\ See Amendment No. 1, supra note 6.
---------------------------------------------------------------------------

    The Commission believes that CBOE's announcement via regulatory 
circular of all applicable parameters relating to the conduct of 
auctions prior to deploying SAL should provide sufficient notice. 
Furthermore, the Commission has approved other rules that grant an 
exchange limited flexibility in determining the details of its market 
structure.\28\ In this case, too, the Commission believes that granting 
the Exchange a limited degree of flexibility in the application of its 
rules is consistent with the Act.
---------------------------------------------------------------------------

    \28\ See, e.g., CBOE Rules 6.45A and 6.45B (regarding allocation 
priority; exchange committee granted the flexibility to determine 
what rules of priority to apply for each class) and AMEX Rule 933 
(Automatic Execution of Options Orders; exchange committee granted 
the flexibility to determine, on an issue-by-issue basis, what order 
types are eligible for Auto-Ex).
---------------------------------------------------------------------------

3. Incentives for Aggressive Quoting
    Citadel expressed its belief that SAL would discourage aggressive 
quoting and would raise baseline prices over time.\29\ According to 
Citadel, market participants quoting at the NBBO would reserve the best 
prices not for display to the general market but for use in the SAL 
auction, and the NBBO would be set artificially wide of the ``true'' 
prices at which market makers are willing to trade.\30\
---------------------------------------------------------------------------

    \29\ See Citadel Letter, supra note 4, at 3.
    \30\ See id.
---------------------------------------------------------------------------

    In response, CBOE notes that SAL would encourage aggressive quoting 
at the NBBO by market makers because market makers at the NBBO would 
have allocation priority in the SAL auction.\31\ The First Allocation 
Round is open only to market makers and customers whose quotes or 
orders represented the Exchange's NBBO at the time the auction 
commenced.\32\ Consequently, it would be advantageous for market makers 
who plan to participate in SAL auctions to quote aggressively to be at 
the Exchange's NBBO and thus be eligible for participation in the First 
Allocation Round. CBOE notes that participation in the First Allocation 
Round is not a ``participation right'' or ``market maker preference.'' 
Rather, CBOE believes, it is an incentive for participants to 
aggressively quote at the

[[Page 44061]]

NBBO throughout the trading day, since those Original Quoters will have 
priority at each price point over participants who are not Original 
Quoters.\33\ The Commission similarly believes that the proposed 
allocation algorithm should not discourage market makers from quoting 
aggressively on the Exchange and is consistent with the Act.
---------------------------------------------------------------------------

    \31\ See Amendment No. 1, supra note 6.
    \32\ See proposed CBOE Rule 6.13A(c)(i).
    \33\ See Amendment No. 1, supra note 6.
---------------------------------------------------------------------------

4. Compliance with the Quote Rule
    Citadel raises a concern that SAL would increase risk and decrease 
aggressive quoting by freezing market maker NBBO quotes for the 
duration of the auction.\34\ CBOE responds by noting that the stop 
feature is necessary to ensure market makers' compliance with firm 
quote obligations.\35\ The Commission believes that the proposal to 
stop market maker NBBO quotes for the duration of the auction is 
designed to ensure compliance with Rule 602 under the Act,\36\ known as 
the Commission's Quote Rule, and is consistent with the Act.
---------------------------------------------------------------------------

    \34\ See Citadel Letter, supra note 4, at 2-3.
    \35\ See Response Letter, supra note 5, at 2.
    \36\ 17 CFR 242.602.
---------------------------------------------------------------------------

5. Opportunity for Market Manipulation
    BOX comments that the proposed rule as originally filed was 
unclear, ambiguous, and provided excessive opportunities for price and 
market manipulation by market participants.\37\ CBOE notes that 
manipulation causing early termination is possible with any auction, 
and points out that the proposed SAL rule prohibits such conduct.\38\ 
The Commission believes that the proposed rule, as amended, provides 
sufficient clarity and guidelines. In addition, the Commission expects 
the Exchange to surveil and discipline its members for improper 
conduct, which would constitute a violation of Exchange rules,\39\ as 
well as the Act and the rules thereunder.\40\
---------------------------------------------------------------------------

    \37\ See BOX Letter, supra note 4, passim.
    \38\ See Response Letter, supra note 5, at 3.
    \39\ See proposed CBOE Rule 6.13A, Interpretation & Policy .01, 
and CBOE Rule 4.1.
    \40\ See, e.g., Section 10(b) of the Act, 15 U.S.C. 78j(b), and 
Rules 10b-3 and 10b-5 thereunder, 17 CFR 240.10b-3 and -5.
---------------------------------------------------------------------------

6. Locked Markets
    Finally, BOX questions both the rationale for terminating SAL early 
when an auction response locks CBOE's quote on the opposite side of the 
market and why the order that creates the quote lock would not be 
treated as an unrelated order and permitted to interact with the SAL 
auction.\41\ In Amendment No. 1, CBOE clarified that if a quote lock on 
the Exchange terminates a SAL auction early at a price that is 
favorable to the auctioned order, then the auctioned order would trade 
at that price to the fullest extent possible.\42\ If the quote lock 
occurs at a price that is inferior to the auction responses, then the 
Agency Order would trade against the best auction responses.\43\
---------------------------------------------------------------------------

    \41\ See BOX Letter, supra note 4, at 8.
    \42\ See Amendment No. 1, supra note 6.
    \43\ See id.
---------------------------------------------------------------------------

B. Automatic Executions During Crossed Markets

    In today's increasingly electronic marketplace, crossed markets 
reflect the number and speed of electronic quotations and the number of 
market makers submitting such quotations. The Commission believes that 
permitting automatic executions during crossed markets when the 
Exchange is at the NBBO for the relevant side of the market, as 
proposed by the Exchange, will allow investors' orders to be handled 
more promptly and expedite the resolution of locked markets.
    The Commission notes, however, that in the event the Exchange 
automatically executes orders when its disseminated market is crossed 
by, or crosses, the disseminated market of another options exchange, 
the Exchange would be permitting trade-throughs \44\ in contravention 
of Section 8(c) of the Plan for the Purpose of Creating and Operating 
in Intermarket Options Linkage (``Linkage Plan'') and CBOE Rule 
6.83.\45\ The Commission believes that it is appropriate and in the 
public interest for the Exchange to except members from trade-through 
liability in the event that the trade-through occurred as a result of 
an automatic execution when the Exchange's disseminated market is the 
NBBO and crossed by, or crosses, the disseminated market of another 
options exchange. The Commission believes that, in this limited 
circumstance, the benefit of providing an automatic execution of orders 
in a crossed market will outweigh the harm of the resultant trade-
through. Therefore, concurrent with this order, the Commission is 
granting CBOE an exemption from the requirement under Exchange Act Rule 
608(c) of the Linkage Plan, which provides that, ``absent reasonable 
justification and during normal market conditions, members in 
[Participants'] markets should not effect trade-throughs,'' and from 
Section 4(b) of the Linkage Plan, which requires the Exchange to 
enforce compliance by its members with Section 8(c) of the Linkage 
Plan.\46\
---------------------------------------------------------------------------

    \44\ A ``Trade-Through'' is defined in Section 2(29) of the 
Linkage Plan as ``a transaction in an options series at a price that 
is inferior to the NBBO.''
    \45\ The Linkage Plan is a national market system plan approved 
by the Commission pursuant to Section 11A of the Exchange Act, 15 
U.S.C. 78k-1, and Exchange Act Rule 608. See Securities Exchange Act 
Release No. 43086 (July 28, 2000), 65 FR 48023 (August 4, 2000).

V. Accelerated Approval of Amendments No. 1, 2, and 3

    The Commission finds good cause to approve Amendments No. 1, 2, and 
3 to the proposed rule change prior to the thirtieth day after the 
amendments are published for comment in the Federal Register pursuant 
to Section 19(b)(2) of the Act.\47\ As discussed in detail above, in 
Amendment No. 1, CBOE proposed revisions to the proposed rule change to 
address some of the concerns raised by Citadel and BOX. In addition, 
CBOE proposed in Amendment No. 1 to clarify, among other things, how 
CBOE would notify its members with respect to order eligibility for 
SAL, when SAL would not be automatically initiated, and how orders 
would be handled upon early termination of SAL due to a quote lock or a 
response matching the Exchange's disseminated quote on the opposite 
side of the market. In Amendment No. 2, the Exchange proposed 
amendments to clarify that the Exchange will submit eligible orders for 
SAL auctioning and automatically execute eligible orders even if 
disseminated market in the subject option class is crossed, provided 
that the Exchange is at the NBBO for the relevant side of the market. 
In Amendment No. 3, the Exchange proposed to except members from trade-
through liability in the case of a trade-through that results from an 
automatic execution when the Exchange's disseminated market is the NBBO 
and is crossed by, or crosses, the disseminated market of another 
options exchange.

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

    The Commission believes that the proposed changes in Amendment No. 
1 are necessary for understanding the operation of SAL, are responsive 
to issues raised in the comment letters, and raise no new issues of 
regulatory concern. In addition, the proposed changes in Amendments No. 
2 and 3 are necessary to the operation of SAL and are similar to rule 
changes previously approved by the Commission for the Philadelphia 
Stock Exchange.\48\ Accordingly, pursuant to Section 19(b)(2) of the 
Act,\49\ the Commission finds good cause exists to approve Amendments 
No. 1, 2, and 3 prior to the thirtieth day after notice of the 
amendments in the Federal Register.

2006), 71 FR 13441 (March 15, 2006) (File No. SR-Phlx-2005-45).
    \49\ 15 U.S.C. 78s(b)(2).

VI. Conclusion

    For the foregoing reasons, the Commission finds that the proposed 
rule change, as amended, is consistent with the requirements of the Act 
and the rules and regulations thereunder applicable to a national 
securities exchange, and, in particular, with Section 6(b)(5) of the 
Act.\50\
---------------------------------------------------------------------------

    \50\ 15 U.S.C. 78f(b)(5). In connection with the issuance of 
this approval order, neither the Commission nor its staff is 
granting any exemptive or no-action relief from the requirements of 
Rule 10b-10 under the Act. 17 CFR 240.10b-10. Accordingly, a broker-
dealer executing a customer order through the SAL auction or 
otherwise on the Exchange will need to comply with all applicable 
requirements of that Rule.
---------------------------------------------------------------------------

    It is therefore ordered, pursuant to Section 19(b)(2) of the 
Act,\51\ that the proposed rule change (SR-CBOE-2005-90) is approved, 
and that Amendments No. 1, 2, and 3 thereto are approved on an 
accelerated basis.
---------------------------------------------------------------------------

    For the Commission, by the Division of Market Regulation, 
pursuant to delegated authority.\52\
