SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-61785; File No. SR-CBOE-2010-021]

 
Self-Regulatory Organizations; Chicago Board Options Exchange, 
Incorporated; Notice of Proposed Rule Change Relating to Correlated 
Instrument Delta Hedge Exemption

March 25, 2010.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(``Act'') \1\ and Rule 19b-4 thereunder,\2\ notice is hereby given that 
on March 19, 2010, the Chicago Board Options Exchange, Incorporated 
(``Exchange'' or ``CBOE'') filed with the Securities and Exchange 
Commission (``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.
---------------------------------------------------------------------------

    \1\ 15 U.S.C. 78s(b)(1).
    \2\ 17 CFR 240.19b-4.
---------------------------------------------------------------------------

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

    CBOE proposes to (i) expand the delta hedging exemption available 
for equity options position limits, (ii) amend the reporting 
requirements applicable to members relying on the delta hedging 
exemption, and (iii) adopt a delta hedging exemption from certain index 
options position limits. The text of the rule proposal is available on 
the Exchange's Web site (http://www.cboe.org/legal), at the Exchange's 
Office of the Secretary 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 
Statutory Basis for, the Proposed Rule Change

1. Purpose

I. Expansion of Delta-Based Equity Hedge Exemption

    On December 14, 2007,\3\ the Commission approved a proposed rule 
change establishing an exemption from equity options position and 
exercise limits for positions held by CBOE members, and certain of 
their affiliates, that are ``delta neutral'' \4\ under a ``permitted 
pricing model'' \5\, subject to certain conditions (``Exemption'').
---------------------------------------------------------------------------

    \3\ See Securities Exchange Act Release No. 56970 (December 14, 
2007), 72 FR 72428 (December 20, 2007). The exemption was extended 
to certain customers whose accounts are carried by a member. See 
Securities Exchange Act Release No. 60555 (August 21, 2009), 74 FR 
43741 (August 27, 2009).
    \4\ The term ``delta neutral'' is defined in Rule 4.11.04(c)(A) 
as referring to an equity option position that is hedged, in 
accordance with a permitted pricing model, by a position in the 
underlying security or one or more instruments relating to the 
underlying security, for the purpose of offsetting the risk that the 
value of the option position will change with incremental changes in 
the price of the security underlying the option position.
    \5\ Permitted pricing model is defined in Rule 4.11.04(c)(C).
---------------------------------------------------------------------------

    The ``options contract equivalent of the net delta'' of a hedged 
equity option position is subject to the position limits under Rule 
4.11, subject to the availability of other exemptions.\6\ Currently, 
the Exemption only is available for securities that directly underlie 
the applicable option position. This means that with respect to options 
on exchange-traded funds (``ETF options''), index options overlying the 
same index on which the ETF is based currently cannot be combined with 
the ETF options to calculate a net delta for purposes of the Exemption.
---------------------------------------------------------------------------

    \6\ The term ``options contract equivalent of the net delta'' is 
defined in Rule 4.11.04(c)(B) as the net delta divided by the number 
of shares underlying the option contract. The term ``net delta'' is 
defined in the same rule to mean, at any time, the number of shares 
(either long or short) required to offset the risk that the value of 
an equity option position will change with incremental changes in 
the price of the security underlying the option position, as 
determined in accordance with a permitted pricing model.
---------------------------------------------------------------------------

    Many ETF options overlie exchange-traded funds that track the 
performance of an index. For example, options on Standard & Poor's 
Depositary Receipts (``SPY'') track the performance of the S&P 500 
index. Market participants often hedge SPY options with options on the 
S&P 500 Index (``SPX options'') or with other financial instruments 
based on the S&P 500 Index for risk management purposes. The Exchange 
believes that in order for eligible market participants to more fully 
benefit from the Exemption as it relates to ETF options, securities and 
other instruments that are based on the same underlying ETF or the same 
index on which the ETF is based should also be included in any 
determination of an ETF option position's net delta or whether the 
options position is hedged delta neutral.\7\
---------------------------------------------------------------------------

    \7\ However, this would not include baskets of securities for 
purposes of the Exemption.
---------------------------------------------------------------------------

    Accordingly, the Exchange proposes to expand the Exemption by 
amending Rule 4.11.04(c)(A) to permit equity option positions for which 
the underlying security is an ETF that is based on the same index as an 
index option to be combined with an index option position for 
calculation of the delta-based equity hedge exemption. The proposed 
rule would allow financial products such as securities index options, 
index futures, and options on index futures to be included along with 
the ETF in an equity option's net delta calculation. So for example, 
the proposed rule would allow SPY options to be hedged not only with 
SPY shares, but with S&P 500 options, S&P 500 futures, options on S&P 
500 futures or any other instrument that tracks the performance of or 
is based on the S&P 500 index. This would be accomplished by including 
such positions with a related index option position in accordance with 
the Delta-Based Index Hedge Exemption rule proposed below.
    Index options and equity options (i.e., ETF options) that are 
eligible to be combined for computing a delta-based hedge exemption, 
along with all securities and/or other instruments that are based on or 
track the performance of the same underlying security or index, will be 
grouped and the net delta and options contract equivalent of the net 
delta will be calculated for each respective option class based on 
offsets realized from the grouping as a whole.

[[Page 16889]]

    The Exchange proposes to amend the definition of ``net delta'' in 
Rule 4.11.04(c)(B) to mean, at any time, the number of shares and/or 
other units of trade \8\ (either long or short) required to offset the 
risk that the value of an equity option position will change with 
incremental changes in the price of the security underlying the option 
position, as determined in accordance with a permitted pricing model. 
The Exchange proposes to amend the definition of the ``option contract 
equivalent of the net delta'' to mean the net delta divided by the 
number of shares that equate to one option contract on a delta 
basis.\9\
---------------------------------------------------------------------------

    \8\ ``Other units of trade'' would include, for example, options 
or futures contracts hedging the relevant option position. When 
determining whether an ETF option hedged with other instruments such 
as ETF or index options is delta neutral, the relative size of the 
ETF option when compared to the other product is taken into 
consideration. For example, SPX options are ten (10) times larger 
than SPY options thus 1 SPX delta is equivalent to .10 SPY deltas.
    \9\ The Exchange also proposes to amend Rule 4.11.04(c)(C)(2) to 
clarify that there is no longer a consolidated supervision program 
by the SEC pursuant to Appendix E of Rule 15c3-1 of the Act.
---------------------------------------------------------------------------

II. Reporting Requirement

    Rule 4.11.04(c)(F) sets forth the reporting requirements applicable 
to CBOE members who rely on the Exemption. The Exchange proposes to 
amend Rule 4.11.04(c)(F) to exempt from the reporting requirements 
Exchange Market-Makers and Designated Primary Market-Makers (``DPMs'') 
relying on the Exemption who use the Options Clearing Corporation 
(``OCC'') pricing model, because Market-Maker and DPM position and 
delta information can be accessed through the Exchange's market 
surveillance systems. This proposed exemption is consistent with 
similar exemptions from the reporting requirements under Rule 4.13 and 
those applicable to broad-based index options and FLEX options.\10\
---------------------------------------------------------------------------

    \10\ See Rules 4.13(b), 24.4.03 and 24A.7(b) and (c).
---------------------------------------------------------------------------

III. Delta-Based Index Hedge Exemption

    Most index options traded on the Exchange are subject to position 
and exercise limits, as provided under CBOE Rules 24.4, 24.4A and 
24.4B.\11\ Certain broad-based index options are not subject to 
position and exercise limits.\12\ Position limits are imposed, 
generally, to prevent the establishment of options positions that can 
be used or might create incentives to manipulate or disrupt the 
underlying market so as to benefit the holder of the options position.
---------------------------------------------------------------------------

    \11\ Rules 24.4, 24.4A and 24.4B provide position limits for 
broad-based index options, industry index options and micro narrow-
based index options, respectively.
    \12\ Broad-based index options not subject to position and 
exercise limits are DJX, OEX, XEO, NDX, RUT, VIX, VXN, VXD and SPX. 
See CBOE Rules 24.4(a) and 24.5.
---------------------------------------------------------------------------

    Index options are often used by market participants such as 
institutional investors to hedge large portfolios. Exchange rules 
include hedge exemptions to allow certain positions in index options in 
excess of the applicable standard position limit if hedged with an 
Exchange-approved qualified portfolio.\13\ Under Rule 24.4.01(c) 
(broad-based index hedge exemption), a qualified portfolio may consist 
of common stocks or securities readily convertible to common stock, 
and/or index futures contracts, options on index futures contracts, or 
long or short positions in index options or index warrants that meet 
certain standards. Under Rule 24.4A.01(a) (industry index hedge 
exemption), a qualified portfolio may consist only of underlying 
component stocks or in securities readily convertible to such component 
stocks. In the case of both hedge exemptions, the maximum size of the 
exempt position is set at a specified maximum number of contracts.
---------------------------------------------------------------------------

    \13\ See Interpretation and Policy .01 to Rule 24.4 (broad-based 
index hedge exemption) and Interpretation and Policy .01 to Rule 
24.4A (industry index hedge exemption).
---------------------------------------------------------------------------

    The Exchange believes that any limit on the ability of market 
participants to use index options to hedge their portfolios exposes 
market participants to unnecessary risk on the unhedged portion of 
their portfolios. The Exchange proposes to adopt a delta-based 
exemption from index option position and exercise limits that is 
substantially similar to the delta-based equity hedge exemption under 
Rule 4.11.04(c). A delta-based index hedge exemption would provide 
market participants the ability to accumulate an unlimited number of 
index options contracts provided that such contracts are properly delta 
hedged in accordance with the requirements of the exemption.
    Proposed Exemption. The Exchange proposes to adopt an exemption 
from index options position and exercise limits \14\ for positions held 
by CBOE members and certain of their affiliates, and customers that are 
``delta neutral'' (as defined below) under a ``permitted pricing 
model'' (as defined below), subject to certain conditions (``Index 
Exemption''). The Index Exemption under proposed Rule 24.4.05 would 
also apply to industry index options under proposed Rule 24.4A.03.
---------------------------------------------------------------------------

    \14\ Exchange Rule 24.5 establishes exercise limits for an index 
option at the same level as the index option's position limit under 
index options position limit rules, therefore no changes are 
proposed to Rule 24.5.
---------------------------------------------------------------------------

    The term ``delta neutral'' is defined in proposed Rule 24.4.05(A) 
as referring to an index option position that is hedged, in accordance 
with a permitted pricing model, by a position in one or more correlated 
instruments for the purpose of offsetting the risk that the value of 
the option position will change with incremental changes in the value 
of the underlying index. Correlated instruments would be defined to 
mean securities and/or other instruments that track the performance of 
or are based on the same underlying index as the index underlying the 
option position. These definitions would allow financial products such 
as ETF options, index futures, options on index futures and ETFs that 
track the performance of or are based on the same underlying index to 
be included in an index option's net delta calculation.\15\
---------------------------------------------------------------------------

    \15\ See Supra footnote 5 (sic).
---------------------------------------------------------------------------

    Any index option position that is not delta neutral would be 
subject to position and exercise limits, subject to the availability of 
other exemptions. Only the ``options contract equivalent of the net 
delta'' of such position would be subject to the appropriate position 
limit.\16\
---------------------------------------------------------------------------

    \16\ Under proposed Rule 24.4.05(B), the term ``options contract 
equivalent of the net delta'' is defined as the net delta divided by 
units of trade that equate to one option contract on a delta basis, 
and the term ``net delta'' is defined as, at any time, the number of 
shares and/or other units of trade (either long or short) required 
to offset the risk that the value of an index option position will 
change with incremental changes in the value of the underlying 
index, as determined in accordance with a permitted pricing model.
---------------------------------------------------------------------------

    In addition, members could not use the same positions in correlated 
instruments in connection with more than one hedge exemption. 
Therefore, a position in correlated instruments used as part of a delta 
hedging strategy could not also serve as the basis for any other index 
hedge exemption.
    Permitted Pricing Model. Under the proposed rule, the calculation 
of the delta for any index option position, and the determination of 
whether a particular index option position is hedged delta neutral, 
must be made using a permitted pricing model. A ``permitted pricing 
model'' is defined in proposed Rule 24.4.05(C) to have the same meaning 
as defined in Rule 4.11.04(c)(C), namely, the pricing model maintained 
and operated by OCC and the pricing models used by (i) a member or its 
affiliate subject to consolidated supervision by the SEC or pursuant to 
Appendix E of SEC Rule 15c3-1; (ii) a financial holding company 
(``FHC'') or a company treated as an FHC under the

[[Page 16890]]

Bank Holding Company Act of 1956, or its affiliate subject to 
consolidated holding company group supervision; \17\ (iii) an SEC 
registered OTC derivatives dealer; \18\ and (iv) a national bank.\19\ 
Customers seeking to use the delta-based index hedge exemption could 
only hedge their position in accordance with the OCC model.
---------------------------------------------------------------------------

    \17\ The pricing model of an FHC or of an affiliate of an FHC 
would have to be consistent with: (i) The requirements of the Board 
of Governors of the Federal Reserve System (``Fed''), as amended 
from time to time, in connection with the calculation of risk-based 
adjustments to capital for market risk under capital requirements of 
the Fed, provided that the member or affiliate of a member relying 
on this exemption in connection with the use of such model is an 
entity that is part of such company's consolidated supervised 
holding company group; or (ii) the standards published by the Basel 
Committee on Banking Supervision, as amended from time to time and 
as implemented by such company's principal regulator, in connection 
with the calculation of risk-based deductions or adjustments to or 
allowances for the market risk capital requirements of such 
principal regulator applicable to such company--where ``principal 
regulator'' means a member of the Basel Committee on Banking 
Supervision that is the home country consolidated supervisor of such 
company--provided that the member or affiliate of a member relying 
on this exemption in connection with the use of such model is an 
entity that is part of such company's consolidated supervised 
holding company group. See subparagraph (C) of proposed Rule 
24.4.05, which incorporates Rule 4.11.04(c)(C).
    \18\ The pricing model of an SEC registered OTC derivatives 
dealer would have to be consistent with the requirements of Appendix 
F to SEC Rule 15c3-1 and SEC Rule 15c3-4 under the Act, as amended 
from time to time, in connection with the calculation of risk-based 
deductions from capital for market risk thereunder. Only an OTC 
derivatives dealer and no other affiliated entity (including a 
member) would be able to rely on this part of the Exemption. See 
subparagraph (C) of proposed Rule 24.4.05, which incorporates Rule 
4.11.04(c)(C).
    \19\ The pricing model of a national bank would have to be 
consistent with the requirements of the Office of the Comptroller of 
the Currency, as amended from time to time, in connection with the 
calculation of risk-based adjustments to capital for market risk 
under capital requirements of the Office of the Comptroller of the 
Currency. Only a national bank and no other affiliated entity 
(including a member) would be able to rely on this part of the 
Exemption. See subparagraph (C) of proposed Rule 24.4.05, which 
incorporates Rule 4.11.04(c)(C).
---------------------------------------------------------------------------

    Aggregation of Accounts. Members, non-member affiliates and 
customers relying on the Index Exemption would be required to ensure 
that the permitted pricing model is applied to all positions in 
correlated instruments hedging the relevant option position that are 
owned or controlled by the member, or its affiliates.
    However, the net delta of an index option position held by an 
entity entitled to rely on the Index Exemption, or by a separate and 
distinct trading unit of such entity, may be calculated without regard 
to positions in correlated instruments held by an affiliated entity or 
by another trading unit within the same entity, provided that: (i) The 
entity demonstrates to the Exchange's satisfaction that no control 
relationship, as defined in Rule 4.11.03, exists between such 
affiliates or trading units, and (ii) the entity has provided the 
Exchange written notice in advance that it intends to be considered 
separate and distinct from any affiliate, or, as applicable, which 
trading units within the entity are to be considered separate and 
distinct from each other for purposes of the Index Exemption.\20\ The 
Exchange has set forth in Regulatory Circular RG08-12 the conditions 
under which it will deem no control relationship to exist between 
affiliated broker-dealers and between separate and distinct trading 
units within the same broker-dealer.
---------------------------------------------------------------------------

    \20\ See subparagraph (D) of proposed Rule 24.4.05.
---------------------------------------------------------------------------

    Any member, non-member affiliate or customer relying on the Index 
Exemption must designate, by prior written notice to the Exchange, each 
trading unit or entity whose options positions are required by Exchange 
rules to be aggregated with the options positions of such member, non-
member affiliate or customer relying on the Index Exemption for 
purposes of compliance with Exchange position or exercise limits.\21\
---------------------------------------------------------------------------

    \21\ See proposed Rule 24.4.05(D)(3).
---------------------------------------------------------------------------

    Obligations of Members and Affiliates. Any member relying on the 
Index Exemption would be required to provide a written certification to 
the Exchange that it is using a permitted pricing model as defined in 
the rule for purposes of the Index Exemption. In addition, by such 
reliance, such member would authorize any other person carrying for 
such member an account including, or with whom such member has entered 
into, a position in a correlated instrument hedging the relevant option 
position to provide to the Exchange or OCC such information regarding 
such account or position as the Exchange or OCC may request as part of 
the Exchange's confirmation or verification of the accuracy of any net 
delta calculation under this exemption.\22\
---------------------------------------------------------------------------

    \22\ See subparagraph (E) of proposed Rule 24.4.05.
---------------------------------------------------------------------------

    The index option positions of a non-member affiliate relying on the 
Index Exemption must be carried by a member with which it is 
affiliated. A member carrying an account that includes an index option 
position for a non-member affiliate that intends to rely on the Index 
Exemption would be required to obtain from such non-member affiliate a 
written certification that it is using a permitted pricing model as 
defined in the rule for purposes of the Index Exemption.\23\
---------------------------------------------------------------------------

    \23\ In addition, the member would be required to obtain from 
such non-member affiliate a written statement confirming that such 
non-member affiliate: (a) Is relying on the Index Exemption; (b) 
will use only a permitted pricing model for purposes of calculating 
the net delta of its option positions for purposes of the Index 
Exemption; (c) will promptly notify the member if it ceases to rely 
on the Index Exemption; (d) authorizes the member to provide to the 
Exchange or the OCC such information regarding positions of the non-
member affiliate as the Exchange or OCC may request as part of the 
Exchange's confirmation or verification of the accuracy of any net 
delta calculation under the Index Exemption; and (e) if the non-
member affiliate is using the OCC Model, has duly executed and 
delivered to the Exchange such documents as the Exchange may require 
to be executed and delivered to the Exchange as a condition to 
reliance on the Exemption. See subparagraph (E)(3) of proposed Rule 
24.4.05.
---------------------------------------------------------------------------

    A member carrying an account that includes an index option position 
for a customer that intends to rely on the Index Exemption would be 
required to obtain from such customer and provide to the Exchange a 
written certification that the customer is using the OCC Model as 
defined in the rule for purposes of the Index Exemption.\24\
---------------------------------------------------------------------------

    \24\ In addition, the member would be required to obtain from 
such customer a written statement confirming that such customer: (a) 
Is relying on this exemption; (b) will use only the OCC Model for 
purposes of calculating the net delta of the customer's option 
positions for purposes of this exemption; (c) will promptly notify 
the member if the customer ceases to rely on this exemption; (d) in 
connection with using the OCC Model, has duly executed and delivered 
to the member such documents as the Exchange may require to be 
executed and delivered to the Exchange as a condition to reliance on 
this exemption.
---------------------------------------------------------------------------

    Reporting. Under proposed Rule 24.4.05(F), each member (other than 
an Exchange Market-Maker, DPM or LMM using the OCC Model) relying on 
the Index Exemption would be required to report, in accordance with 
Rule 4.13,\25\ (i) all index option positions (including those that are 
delta neutral) that are reportable thereunder, and (ii) on its own 
behalf or on behalf of a designated aggregation unit pursuant to Rule 
24.4.05(D), for each such account that holds an index option position 
subject to the Index Exemption in excess of the levels specified in 
Rule 24.4 (and Rule 24.4A, in the case of industry index options) the 
net delta and the options contract equivalent of the net delta of such 
position.
---------------------------------------------------------------------------

    \25\ Exchange Rule 4.13 requires, among other things, that 
members report to the Exchange aggregate long or short positions on 
the same side of the market of 200 or more contracts of any single 
class of options contracts dealt in on the Exchange.
---------------------------------------------------------------------------

    Records. Under proposed Rule 24.4.05(G), each member relying on the 
Index Exemption would be required to (i) retain, and would be required 
to undertake reasonable efforts to ensure that any non-member affiliate 
of the

[[Page 16891]]

member or customer relying on the Index Exemption retains, a list of 
the options, securities and other instruments underlying each options 
position net delta calculation reported to the Exchange hereunder, and 
(ii) produce such information to the Exchange upon request.\26\
---------------------------------------------------------------------------

    \26\ A member would be authorized to report position information 
of its non-member affiliate pursuant to the written statement 
required under proposed Rule 24.4.05(E)(3)(ii)(d).
---------------------------------------------------------------------------

    Reliance on Federal Oversight. As provided under proposed Rule 
24.4.05(C), a permitted pricing model includes proprietary pricing 
models used by members and affiliates that have been approved by the 
SEC, the Fed or another Federal financial regulator. In adopting the 
proposed Index Exemption the Exchange would be relying upon the 
rigorous approval processes and ongoing oversight of a Federal 
financial regulator. The Exchange notes that it would not be under any 
obligation to verify whether a member's or its affiliate's use of a 
proprietary pricing model is appropriate or yielding accurate results.
    The Exchange will announce the effective date of the proposed rule 
change in a regulatory circular to be published no later than 60 days 
after Commission approval. The effective date shall be no later than 30 
days after publication of the regulatory circular.
2. Statutory Basis
    The Exchange believes that this proposed rule change is consistent 
with Section 6(b) of the Securities Exchange Act of 1934 (``Act'') 
\27\, in general, and furthers the objectives of Section 6(b)(5) of the 
Act \28\ in particular, in that it is designed to prevent fraudulent 
and manipulative acts and practices, 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, 
to protect investors and the public interest. The Exchange believes 
that allowing correlated instruments to be included in the calculation 
of an equity option's net delta would enable eligible market 
participants to more fully realize the benefit of the delta based 
equity hedge exemption. The proposed delta-based index hedge exemption 
would be substantially similar to the delta-based equity hedge 
exemption under Rule 4.11.04. Also, the Commission has previously 
stated its support for recognizing options positions hedged on a delta 
neutral basis as properly exempted from position limits.\29\

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

    CBOE does not believe that the proposed rule change will impose any 
burden on competition not necessary or appropriate in furtherance of 
the purposes of the Act.

Commission Action

    Within 35 days of the date of publication of this notice in the 
Federal Register or within such longer period (i) as the Commission may 
designate up to 90 days of such date if it finds such longer period to 
be appropriate and publishes its reasons for so finding or (ii) as to 
which the self-regulatory organization consents, the Commission will:
    (a) By order approve such proposed rule change, or
    (b) Institute proceedings to determine whether the proposed rule 
change should be disapproved.
