Self-Regulatory Organizations; Chicago Board Options Exchange, 
Incorporated; Notice of Filing of a Proposed Rule Change Related to Its 
Obvious Error Rules

April 20, 2009.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(the ``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given 
that on April 8, 2009, the Chicago Board Options Exchange, Incorporated 
(the ``Exchange'' or ``CBOE'') filed with the Securities and Exchange 
Commission (the ``Commission'') the proposed rule change as described 
in Items I, II, and III below, which Items have been prepared by the 
Exchange. The Commission is publishing this notice to solicit comments 
on the proposed rule change from interested persons.

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

    The Exchange proposes to amend Rules 6.25, Nullification and 
Adjustment of Equity Options Transactions, and 24.16, Nullification and 
Adjustment of Transactions in Index Options, Options on ETFs and 
Options on HOLDRS. The text of the proposed rule change is available on 
the Exchange's Web site (http://www.cboe.org/Legal), at the Office of 
the Secretary, CBOE and at the Commission.

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 self-regulatory organization 
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 those 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 parts of such statements.

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

1. Purpose
    CBOE proposes to amend Rules 6.25 and 24.16, pertaining to the 
nullification and adjustment of options transactions, in several 
respects.
    Merging Rules. The Exchange is proposing to merge Rule 24.16 (which 
currently relates to only index, ETF and HOLDRS options) into Rule 6.25 
(which currently relates to only equity options) to form a single 
obvious error rule. This merger will simplify the administration of the 
rules and incorporate a uniform obvious error approach for all equity, 
index, ETF, and HOLDRS options.
    Obvious Pricing Errors. The Exchange is proposing certain changes 
to the Obvious Pricing Error provision of Rule 6.25. Under the current 
rule, an Obvious Pricing Error occurs when the execution price of an 
electronic transaction is above or below the Theoretical Price for the 
series by a specified amount. For purpose of the rule, the 
``Theoretical Price'' of an option series is currently defined, for 
series traded on at least one other options exchange, as the last bid 
price with respect to an erroneous sell transaction and the last offer 
price with respect to an erroneous buy transaction, just prior to the 
trade, disseminated by the competing options exchange that has the most 
liquidity in that option class in the previous two calendar months. If 
there are no quotes for comparison, Trading Officials \3\ determine the 
Theoretical Price.
---------------------------------------------------------------------------

    \3\ The term ``Trading Officials'' currently means two Exchange 
members designated as Floor Officials and one member of the 
Exchange's staff designated to perform Trading Official functions. 
See Rules 6.25.02 and 24.16.02.
---------------------------------------------------------------------------

    First, the Exchange is proposing to amend Rule 6.25's definition of 
``Theoretical Price'' to base it on the national best bid or offer 
(``NBBO'') instead of the market with the most

[[Page 18763]]

liquidity. Using the NBBO to define Theoretical Price is similar to how 
``fair market value'' is currently defined for obvious pricing errors 
under Rule 24.16.\4\
---------------------------------------------------------------------------

    \4\ Under Rule 24.16, an Obvious Pricing Error is currently 
deemed to have occurred when the execution price of a transaction is 
above or below the fair market value of the option by at least a 
prescribed minimum error amount. The ``fair market value'' of an 
option is currently defined as the midpoint of the national best bid 
and national best offer for the series (across all exchanges trading 
the option). In multiply listed issues, if there are no quotes for 
comparison purposes, fair market value is determined by Trading 
Officials. For singly listed issues, fair market value is the 
midpoint of the first quote after the transaction(s) in question 
that does not reflect the erroneous transaction(s).
---------------------------------------------------------------------------

    Second, the Exchange is proposing to permit Trading Officials to 
establish the Theoretical Price when the NBBO for the affected series, 
just prior to the erroneous transaction, is at least two times the 
permitted bid/ask differential under subparagraph (b)(iv)(A) of Rule 
8.7, Obligations of Market-Makers. This provision is similar to a 
provision in the Nasdaq OMX Phlx's (``Phlx'') obvious error rule, Phlx 
Rule 1092.
    Third, the Exchange is proposing to provide for the adjustment of 
Obvious Pricing Error transactions involving non-CBOE Market-Makers 
provided the adjusted price does not violate the non-CBOE Market-
Maker's limit price. By comparison, under the current provisions of 
Rule 6.25, such Obvious Pricing Error transactions involving non-CBOE 
Market-Makers are generally nullified (though certain transactions 
involving non-broker-dealer Customer orders are subject to adjustment 
if notification of the error is received more than fifteen minutes 
after the transaction). Allowing for adjustments to the extent possible 
within a non-CBOE Market-Maker's limit price is similar to how Rule 
24.16 currently operates.
    Fourth, the Exchange is proposing to revise the Obvious Pricing 
Error provision as it pertains to transactions occurring as part of the 
Rule 6.2A, Rapid Opening System (``ROS''), or Rule 6.2B, Hybrid Opening 
System (``HOSS''), rotations. Currently, for transactions occurring as 
part of ROS or HOSS, Theoretical Price is defined as the first quote 
after the transaction(s) in question that does not reflect the 
erroneous transaction(s). The Exchange is proposing to revise the 
Theoretical Price calculation to provide additional conditions that 
would apply during regular ROS and HOSS rotations and during HOSS 
rotations in index options series that are being used to calculate the 
final settlement price of volatility indexes. The additional 
conditions, which are the same as the conditions that currently apply 
for HOSS transactions under Rule 24.16, are intended to reasonably 
factor the amount of available liquidity into the Theoretical Price 
calculation during these rotations. Specifically, with respect to 
regular ROS and HOSS rotations, the Exchange is proposing to add a 
condition that the option contract quantity subject to nullification or 
adjustment would not exceed the size of the first quote after the 
transaction(s) in question that does not reflect the erroneous 
transaction(s).\5\ Any nullifications or adjustments would occur on a 
pro rata basis considering the overall size of the ROS or HOSS opening 
trade.\6\
---------------------------------------------------------------------------

    \5\ For erroneous sell transactions, the size of the bid would 
be used. For erroneous buy transactions, the size of the offer would 
be used. For example, assume that the opening transactions in series 
XYZ totaled 200 contracts at a price $0.75. Also assume that a 
member representing non-CBOE Market-Maker A sold 200 contracts, 
trading 100 contracts with CBOE Market-Maker B and 100 contracts 
with non-CBOE Market-Maker C. Finally, assume that the first quote 
after the transaction in question that does not reflect the 
erroneous transaction is bid 100 contracts for $1.10 and offered 150 
contracts at $1.25. In this scenario, an erroneous sell transaction 
would be deemed to have occurred in accordance with the obvious 
price error provision because the $0.75 price received by non-CBOE 
Market-Maker A is lower than the fair market value of $1.10 by at 
least the prescribed minimum error amount of $0.25. In addition, 
because the size of the bid in the first quote after that does not 
reflect the erroneous transaction is for 100 contracts, up to 100 
contracts executed on the opening on behalf of non-CBOE Market-Maker 
A would be subject to nullification or adjustment under the Obvious 
Pricing Error provision.
    \6\ Thus, 50 contracts executed against CBOE Market-Maker B 
would have a price adjustment to $1.10 (provided the adjusted price 
does not violate A's limit price) and 50 contracts executed against 
non-CBOE Market-Maker C would have a price adjustment to $1.10 
(provided the adjusted price does not violate C's limit price).
---------------------------------------------------------------------------

    With respect to HOSS rotations in index options series being used 
to calculate the final settlement price of a volatility index,\7\ the 
Exchange is proposing to carryover a condition from Rule 24.16 that the 
first quote after the transaction(s) in question that does not reflect 
the erroneous transaction(s) must be for at least the size of the HOSS 
opening transaction(s). If the size of the quote is less than the size 
of the opening transaction(s), then the Obvious Pricing Error provision 
shall not apply.\8\
---------------------------------------------------------------------------

    \7\ CBOE's and the CBOE Futures Exchange, LLC's (a designated 
contract market approved by the Commodity Futures Trading Commission 
and a wholly-owned subsidiary of CBOE) rules provide for the listing 
and trading of options and futures, as applicable, on various 
volatility indexes. The Obvious Pricing Error provision would be 
utilized only for those index options series used to calculate the 
final settlement price of a volatility index and only on the final 
settlement date of the options and futures contracts on the 
applicable volatility index in each expiration month. Thus, for 
example, the proposed obvious price error provision would be used 
for the relevant Standard & Poor's 500 Stock Index (``SPX'') options 
series on settlement days for CBOE Volatility Index (``VIX'') 
options and futures contracts.
    \8\ For example, if the opening trade in Series XYZ is for a 
total of 200 contracts and the bid or offer, as applicable, of the 
first quote after the transaction(s) in question that does not 
reflect the erroneous transaction(s) is for 500 contracts, then the 
quote would be used to determine Theoretical Price and whether an 
Obvious Pricing Error occurred. If the bid or offer, as applicable, 
of the quote is for only 100 contracts, then the trade would not be 
subject to nullification or adjustment under the Obvious Pricing 
Error provision.
---------------------------------------------------------------------------

    Fifth, the Exchange is proposing to extend the expanded 
notification period applicable to transactions during opening rotations 
involving non-broker-dealer Customers to include certain orders entered 
before the opening that are executed immediately following the opening 
rotation. Specifically, Rule 6.25 currently requires that members 
notify CBOE Trading Officials or designated personnel in the control 
room within a short time period following the execution of a trade 
(generally 15 minutes) if they believe the trade qualifies as an 
Obvious Pricing Error. However, an expanded notification period is 
available for transactions during option rotation where at least one 
party to the transaction is a non-broker-dealer Customer. The 
application of this expanded notification period is currently limited 
to executions during opening rotations occurring as part of ROS or 
HOSS. The Exchange is proposing to amend the expanded notification 
period to be applicable to transactions involving non-broker-dealer 
Customers' marketable orders that are entered before the opening 
rotation and that are executed as part of the Hybrid Agency Liaison 
(``HAL'') on the opening process, which is an automated procedure that 
auctions marketable orders entered prior to the opening rotation but 
that are not able to be executed as part of the HOSS single clearing 
price under Rule 6.2B.03. The Exchange is also proposing to make the 
expanded notification period applicable to transactions involving non-
broker-dealer Customers' complex orders that are entered before the 
opening rotation and that are executed immediately following the 
opening rotation through the Exchange's electronic Complex Order Book 
under Rule 6.53C, Complex Orders on the Hybrid System, provided such a 
complex order would have been marketable against the opening rotation 
price(s) but for the fact that the complex orders do not eligible to 
participate in the opening rotation process under Rule 6.2B. As with 
our reasoning for adopting the existing relief for transactions during 
ROS and HOSS opening

[[Page 18764]]

rotations, our intention of extending the expanded notification period 
to cover these two scenarios involving orders entered prior to the 
opening rotation is to protect the non-broker-dealer Customer who fails 
to discover an Obvious Pricing Error within 15 minutes of execution 
from being forced to accept an execution price that results from an 
Obvious Pricing Error.
    Lastly with respect to Obvious Pricing Errors in binary options, 
the Exchange is proposing to provide that any price adjustment for a 
binary option series (including any adjustment penalty that may be 
applicable to transactions between CBOE Market-Makers) \9\ shall not 
exceed the applicable exercise settlement amount for the binary option. 
As defined in CBOE Rule 22.1(e), the term ``exercise settlement 
amount'' as when used in reference to a binary option means the amount 
of cash that a holder will receive upon exercise of the contract.\10\
---------------------------------------------------------------------------

    \9\ As discussed further below, Rule 6.25 assesses a ``penalty'' 
in that the adjustment price is not as favorable as what the party 
making the error would have received had it not made the error.
    \10\ This proposed limitation on obvious pricing error 
adjustments for binary options is similar to an existing limitation 
on obvious pricing error adjustments for Credit Options. See Rule 
29.15, Nullification and Adjustments for Credit Option Transactions.
---------------------------------------------------------------------------

Catastrophic Pricing Errors

    The Exchange is proposing to adopt a Catastrophic Pricing Error 
provision to address certain extreme circumstances, which provision 
would be similar to International Securities Exchange's (``ISE'') 
catastrophic pricing error provision, ISE Rule 720. In particular, the 
Exchange proposes to add criteria for identifying ``Catastrophic 
Errors'' and making adjustments when Catastrophic Errors occur, as well 
as a streamlined procedure for reviewing actions taken in these extreme 
circumstances. As discussed above, currently under Rule 6.25, trades 
that result from an Obvious Pricing Error may be adjusted or busted 
according to objective standards. Under the Rule, whether an Obvious 
Pricing Error has occurred is determined by comparing the execution 
price to the Theoretical Price of the option. The rule requires that 
members notify CBOE Trading Officials or designated personnel in the 
control room within a short time period following the execution of a 
trade (generally 15 minutes) if they believe the trade qualifies as an 
Obvious Pricing Error. Trades that qualify for adjustment or nullified 
under the Rule to a price that matches the theoretical price plus or 
minus an adjustment penalty for transactions between CBOE Market-
Makers, which is $0.15 if the Theoretical Value is under $3 and $0.30 
if the Theoretical Value is at or above $3.
    In formulating the Obvious Pricing Error rule, the Exchange has 
weighed carefully the need to assure that one market participant is not 
permitted to receive a windfall at the expense of another market 
participant that made an Obvious Pricing Error, against the need to 
assure that market participants are not simply being given an 
opportunity to reconsider poor trading decisions. The Exchange states 
that, while it believes that the Obvious Pricing Error rule strikes the 
correct balance in most situations, in some extreme situations, members 
may not be aware of errors that result in very large losses within the 
time periods required under the Rule. In this type of extreme 
situation, CBOE believes members should be given more time to seek 
relief so that there is a greater opportunity to mitigate very large 
losses and reduce the corresponding large windfalls. However, to 
maintain the appropriate balance, the Exchange believes members should 
only be given more time when the execution price is much further away 
from the Theoretical Price than is required for Obvious Pricing Errors, 
and that the adjustment ``penalty'' should be much greater, so that 
relief is only provided in extreme circumstances.\11\
---------------------------------------------------------------------------

    \11\ The Exchange does not believe the type of extreme situation 
that is covered by the proposed rule would occur in the normal 
course of trading. Rather, this type of situation could potentially 
occur as a result of, for example, an error in a member's quotation 
system that causes a market maker to severely misprice an option.
---------------------------------------------------------------------------

    Accordingly, the Exchange proposes to amend Rule 6.25 to address 
``Catastrophic Errors.'' Under the new provision, members will have 
until 7:30 a.m. Central Time on the day following the trade to notify 
Trading Officials or designated personnel in the control room of a 
potential Catastrophic Error. For trades that take place in an expiring 
series on expiration Friday, notification must be received by 4 p.m. 
Central Time that same day. Once notification of a Catastrophic Error 
has been received within the required time period, a panel comprised of 
at least one (1) member of the Exchange's staff designated to perform 
Catastrophic Error Panel functions and four (4) Exchange members (the 
``Panel'') will review the Catastrophic Error claim. Fifty percent of 
the number of Exchange members on the Panel must be directly engaged in 
market making activity and fifty percent of the number of Exchange 
members on the Panel must act in the capacity of a floor broker.
    In the event the Panel determines that a Catastrophic Error did not 
occur, the member that initiated the review will be charged $5,000 to 
reimburse the Exchange for the costs associated with reviewing the 
claim. A Catastrophic Error would be deemed to have occurred when the 
execution price of a transaction is higher or lower than the 
Theoretical Price for the option by an amount equal to at least the 
amount shown in the second column of the chart below (the ``Minimum 
Amount''), and the adjustment would be made plus or minus the amount 
shown in column three of the chart below (the ``Adjustment 
Value'').\12\ At all price levels, the Minimum Amount and the 
Adjustment Value for Catastrophic Errors would be significantly higher 
than for Obvious Pricing Errors, which the Exchange believes, would 
limit the application of the proposed rule to situations where the 
losses are very large.
---------------------------------------------------------------------------

    \12\ Under the proposal, the proposed Minimum Amount would be 
the same as the corresponding Adjustment Values for Catastrophic 
Errors. By contrast, under ISE's rule for catastrophic errors, the 
minimum error amount and corresponding adjustment value may vary. 
See proposed CBOE Rule 6.25(a)(1) and (d), and ISE Rule 720(a)(2) 
and (d)(3).

[[Page 18765]]

    Erroneous Prints & Quotes in the Underlying. The Exchange is 
proposing various changes to the provisions of Rule 6.25 relating to 
erroneous prints and quotes in the underlying. Under the current rule, 
an option trade resulting from an erroneous print disseminated by the 
underlying market which is later cancelled or corrected by the 
underlying market may be nullified, provided the option trade results 
from a print that is higher or lower than the average trade in the 
underlying security during a two-minute period before and after the 
erroneous print by an amount at least five times greater than the 
average quote width for such underlying security for the same period. 
For purposes of the erroneous print provision, the ``average trade'' in 
the underlying security is determined by adding the prices of each 
trade during the four minute period (excluding the trade in question) 
and dividing by the number of trades during such time period (excluding 
the trade in question). The ``average quote width'' is determined by 
adding the quote widths for each separate quote during the four minute 
period (excluding the quote in question) and dividing by the number of 
quotes during such time period (excluding the quote in question). In 
addition, electronic trades resulting from an erroneous quote in the 
underlying security may be adjusted or nullified in accordance with the 
adjustment calculation for Obvious Pricing Errors. An ``erroneous 
quote'' occurs when the underlying security has a width of $1 and has a 
width at least five times greater than the average quote width (as 
defined above) for such underlying security on the primary market 
during the period encompassing two minutes before and after the 
dissemination of the quote.
    First, for consistency, the Exchange is proposing to amend the 
provision to allow for adjustments and nullifications of erroneous 
prints in the underlying (currently the provision calls for 
nullifications only). This change to allow for adjustments or 
nullifications is consistent with Rule 6.25's existing treatment of 
erroneous quotes in the underlying market and Rule 24.16's existing 
treatment of erroneous prints and quotes in underlying or related 
instruments.
    Second, to make the administration of the rule less time consuming 
and less burdensome, the Exchange is also proposing to revise the 
provisions to determine the ``average quote width'' in the underlying 
by adding the quote widths of sample quotations at regular 15-second 
intervals during the two minutes preceding and following an erroneous 
transaction. This sampling approach is similar to Phlx Rule 1092.
    Third, the Exchange is proposing to modify the erroneous trade and 
quote provisions to allow the Exchange to designate the applicable 
underlying security(ies) or related instruments for any option, which 
is how Rule 24.16 currently operates for ETF, HOLDRS, and index 
options. Under the revised rule, the Exchange would identify particular 
underlying or, with respect to ETF(s), HOLDRS(s), and index options, 
related instrument(s) that would be used to determine an erroneous 
print or quote and would also identify the relevant market(s) trading 
the underlying or related instrument to which the Exchange would look 
for purposes of applying the obvious error analysis. The ``related 
instrument(s)'' may include related ETF(s), HOLDRS(s), and/or index 
value(s),\13\ and/or related futures product(s),\14\ and the ``relevant 
market(s)'' may include one or more markets. The underlying or related 
instrument(s) and relevant market(s) will be designated by the Exchange 
and announced to the membership via Regulatory Circular. For a 
particular ETF, HOLDRS, index value and/or futures product to qualify 
for consideration as a ``related instrument,'' the revised rule 
requires that: (i) The option class and related instrument must be 
derived from or designed to track the same underlying index; or (ii) in 
the case of S&P 100-related options, the options class and related 
instrument must be derived from or designed to track the S&P 100 Index 
or the S&P 500 Index. Again, this is currently how Rule 24.16 operates 
for ETF, HOLDRS and index options. The only substantive change being 
made by incorporating this provision into Rule 6.25, is that the 
Exchange would now have the ability to designate the ``relevant 
market(s)'' for equity options (whereas currently the Rule 6.25 
references only the ``primary market'').
---------------------------------------------------------------------------

    \13\ An ``index value'' is the value of an index as calculated 
and reported by the index's reporting authority. Use of an index 
value would only be applicable for purposes of identifying an 
erroneous print in the underlying (and not an erroneous quote). See 
Rule 24.16(a)(3).
    \14\ As with Rule 24.16, under Rule 6.25 the Exchange is only 
proposing that it may designate underlying or related ETF(s), 
HOLDRS(s), and/or index value(s), and/or related futures product(s). 
The Exchange is not proposing to designate any of the individual 
underlying stocks (or related options or futures on any of the 
individual underlying stocks) that comprise a particular ETF, HOLDR 
or index. (Any such proposal would be the subject of a separate rule 
filing.)
---------------------------------------------------------------------------

    Thus, as an example for illustrative purposes only, for options on 
the Powershares QQQ Trust (the ``Nasdaq 100 ETF''), the Exchange may 
determine to designate the underlying ETF (ETF symbol ``QQQQ'') and the 
primary market where it trades, as well as a related futures product 
overlying the Nasdaq 100 Index and the primary market where that 
futures product trades, as the instruments that would be considered by 
the Exchange in determining whether an erroneous print or an erroneous 
quote has occurred that would form the basis for an adjustment or 
nullification to a transaction in the related options.\15\ As another 
example for illustrative purposes only, for the Exchange's class of 
options on International Business Machines Corporation, the underlying 
instrument would be IBM. The Exchange may determine to designate one or 
more underlying stock exchanges as the ``relevant market(s),'' such as 
the New York Stock Exchange (``NYSE'') and the CBOE Stock Exchange 
(``CBSX'').\16\ The

[[Page 18766]]

proposed change is intended to address member feedback and to provide 
relief in those scenarios where an erroneous options transaction may 
occur as the result of an erroneous print or erroneous quote in markets 
other than the primary market for the underlying security. The Exchange 
believes the proposed change recognizes that market participants 
trading in the overlying equity, index, ETF and HOLDRS options may base 
their options prices on trading in various products and markets, while 
maintaining reasonable and objective criteria for these types of 
obvious error reviews.
---------------------------------------------------------------------------

    \15\ Using this example, under the revised rule, the designated 
instruments and markets would be announced by Regulatory Circular. 
Thereafter, for a transaction in the QQQ options class to be 
adjusted or nullified due to an erroneous print in an underlying or 
related instrument that is later cancelled or corrected, the trade 
must be the result of: (i) An erroneous print in the underlying 
Nasdaq 100 ETF that is higher or lower than the average trade in the 
underlying Nasdaq 100 ETF on the primary market during a two-minute 
period before and after the erroneous print by an amount at least 
five times greater than the average quote width for the ETF during 
the same period, or (ii) an erroneous print in the designated 
futures product overlying the Nasdaq 100 Index that is higher or 
lower than the average trade in the designated futures product on 
the designated market during a two-minute period before and after 
the erroneous print by an amount at least five times greater than 
the average quote width for the futures product during the same 
period. For an options transaction to be adjusted or nullified due 
to an erroneous quote in an underlying or related instrument, an 
erroneous quote would occur when: (i) The underlying Nasdaq 100 ETF 
has a width of at least $1.00 and has a width at least five times 
greater than the average quote width for such ETF on the primary 
market during the time period encompassing two minutes before and 
after the dissemination of such quote, or (ii) the designated 
futures product overlying the Nasdaq 100 Index has a width of at 
least $1.00 and has a width at least five times greater than the 
average quote width for such futures product on the designated 
market during the period encompassing two minutes before and after 
the dissemination of such quote.
    \16\ Using this example, under the revised rule, the relevant 
market(s) would be announced by Regulatory Circular. Thereafter, for 
a transaction in the IBM options class to be adjusted or nullified 
due to an erroneous print in an underlying security that is later 
cancelled or corrected, the trade must be the result of an erroneous 
report of the underlying IBM stock value on NYSE or CBSX that is 
higher or lower than the average price in the stock on the NYSE or 
CBSX market, as applicable, during a two-minute period before and 
after the erroneous report by an amount at least five times higher 
or lower than the difference between the highest and lowest index 
values during the same period. To be adjusted or nullified due to an 
erroneous quote in the underlying security, an erroneous quote would 
occur when the IBM quote on the NYSE or CBSX market, as applicable, 
has a width of at least $1.00 and has a width at least five times 
greater than the average quote width for IBM on the relevant market 
during the time period encompassing two minutes before and after the 
dissemination of such quote.
---------------------------------------------------------------------------

    Trading Officials & Obvious Error Panels. The Exchange is proposing 
to amend its definition of the term Trading Officials. The term 
``Trading Officials'' is currently defined in Rule 6.25 to mean two 
Exchange members designated as Floor Officials and one member of the 
Exchange's staff designated to perform Trading Official functions. The 
Exchange is proposing to change this definition to mean three Exchange 
officials designated to perform Trading Official functions, at least 
one of which is an Exchange member designated as a Floor Official and 
at least one of which is a member of the Exchange's staff designated to 
perform Trading Official functions. The Exchange is proposing to make 
the change at this time because it recently determined to change the 
composition of its Floor Officials committee to include more Exchange 
staff and the change in composition of the Trading Officials is more in 
keeping with the increasing role of the Exchange staff.
    Finally, the Exchange is proposing to change a reference from 
``non-DPM floor brokers'' to simply ``floor brokers'' in the 
composition requirements for Obvious Error Panels, which review certain 
determinations rendered by Trading Officials and the senior official in 
the Exchange's control room under Rule 6.25(b).\17\ DPMs (which stands 
for Designated Primary Market-Makers) no longer function as floor 
brokers under CBOE Rules, so the Exchange is proposing that the 
outdated reference be removed.\18\
---------------------------------------------------------------------------

    \17\ Currently, Rule 6.25(c)(i) provides that an Obvious Error 
Panel is compromised [sic] of at least one (1) member of the 
Exchange's staff designated to perform Obvious Error Panel functions 
and four (4) Exchange members. The rule also provides that fifty 
percent of the Exchange members on the Obvious Error Panel must be 
directly engaged in market making activity and fifty percent must 
act in the capacity of a non-DPM floor broker.
    \18\ See Securities Exchange Act Release No. 52798 (November 18, 
2005), 70 FR 71344 (November 28, 2005) (SR-CBOE-2005-46) (order 
approving a rule change related to the removal of agency 
responsibilities from DPMs and the establishment of PAR Officials).
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes the proposed rule change is consistent with 
the Act \19\ and the rules and regulations thereunder and, in 
particular, the requirements of Section 6(b) of the Act.\20\ 
Specifically, the Exchange believes the proposed rule change is 
consistent with the Section 6(b)(5) \21\ requirements that the rules of 
an exchange be designed to promote just and equitable principles of 
trade, to prevent fraudulent and manipulative acts, to remove 
impediments to and to perfect the mechanism for a free and open market 
and a national market system, and, in general, to protect investors and 
the public interest. The proposed rule changes will simplify the 
administration of the Exchange's obvious error rules and incorporate a 
uniform obvious error approach for all equity, index, ETF, and HOLDRS 
options while maintaining reasonable and objective criteria for these 
types of reviews.
