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

    The Exchange proposes to amend its rules to enable the initial and 
continued listing and trading on the Exchange of binary options on 
board-based indexes. The text of the proposed rule change is available 
at the Exchange's principal office, the Commission's Public Reference 
Room, and http://www.cboe.org.legal.

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

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

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

1. Purpose
    The purpose of this proposed rule change is to enable the listing 
and trading on the Exchange of binary options on broad-based indexes. 
Binary options have an exercise settlement amount that is equal to the 
applicable exercise settlement value multiplied by the applicable 
contract multiplier. The exercise settlement value would be an amount 
determined by the Exchange on a class-by-class basis and would be 
greater or equal to $10 and less than or equal to $1,000. The contract 
multiplier also would be established on a class-by-class basis and at 
least one. A binary option would be automatically exercised if the 
settlement value of the underlying index equals, exceeds, or is less 
than the exercise price, depending on the type of the option (i.e., 
call or put). Binary options would be based on the same framework as 
existing standardized options that are traded on the Exchange and other 
options exchanges; however, the payout of a binary option is contingent 
upon the occurrence of the option being ``in'' or ``at-the-money'' 
versus the degree to which the option is ``in-the-money.'' As a result, 
payout at expiration would be an ``all-or-nothing'' occurrence.
(1) Characteristics of Binary Options
    The proposed binary options would be European-style and would have 
an exercise settlement amount that is based on the exercise price in 
relation to the settlement value of the underlying broad-based index at 
expiration. After a particular binary option class has been approved 
for listing and trading on the Exchange, the Exchange may open for 
trading series of options on that class. In order to afford investors 
maximum flexibility, binary option series may expire from one day up to 
36 months from the time that they are listed. Binary options would be 
quoted based on the existing strike intervals utilized for traditional 
index options (e.g., $2.50 per contract if the index is below 200 and 
$5.00 per contract is the index is above 200) with minimum price 
variations, established by class, to be no less than $0.01.
    At expiration, a binary option would pay out an exercise settlement 
amount equal to the exercise settlement value multiplied by the 
contract multiplier. Unlike traditional index options, the value of the 
payout is not affected by the magnitude of the difference between the 
underlying index and the exercise price. Rather the payout would be a 
set amount contingent upon whether the settlement value of the 
underlying index is: (1) Equal to or above the exercise price at 
expiration for a binary call option; or (2) below the exercise price at 
expiration for a binary put option.
(2) The OTC Market
    Binary options have been traded in the over-the-counter (``OTC'') 
market for many years. However, OTC binary options have certain 
disadvantages. OTC binary options are typically offered by an 
institution on a non-fungible basis so the customer can purchase or 
close out the option only from the particular institution that is 
issuing the option. As a result, OTC binary options lack transparency 
and a trading market (liquidity). The Exchange's proposal is intended 
to provide the market for binary options with a standardized product 
without the credit risk of an individual issuer. By providing a listed 
and standardized market for a class of binary options, the Exchange 
seeks to attract investors who desire a binary option but at the same 
time prefer the certainty and safeguards of a regulated and 
standardized marketplace.
    Binary options are designed to be a simplified version of 
traditional, exchange-traded options and to provide investors with a 
simple product with an easy to understand risk profile.

[[Page 20986]]

(3) Simplicity
    Binary options are easier to understand and utilize than 
traditional options because of the manner of their payout (i.e., set 
exercise settlement amount if underlying closes at, below, or above the 
exercise price) and because they are cash-settled. A significant 
benefit of a binary option is that the buyer and writer of the option 
know the expected return at the time of purchase if the underlying 
index performs as expected. In contrast, the ``traditional'' option 
does not typically have a known return at the time of purchase, i.e., 
the return cannot be accurately determined until the option is nearing 
expiration due to price movements. In addition, because the return on 
the binary option is a set amount, a buyer of a binary option does not 
need to determine the absolute magnitude of the underlying index's 
price movement relative to the exercise price, as is the case with 
traditional options.
(4) Risk Transparency
    In addition, unlike traditional options where a writer has 
unlimited risk, the maximum obligation in connection with a binary 
option is known when the contract is written. And, unlike with an OTC 
binary option, counter-party credit risk is significantly reduced 
through the issuance and guarantee of the contracts by The Options 
Clearing Corporation (``OCC'').
(5) Liquidity
    As an exchange-traded option, binary options would have the 
advantage of liquidity provided by market makers, and therefore, 
spreads should be tighter than in the OTC market. Further, the Exchange 
believes that standardization would enable more interested parties to 
become market participants. In other words, CBOE's proposal offers a 
more transparent and level playing field than the OTC market.
Discussion of Particular Rules
(1) Definitions (Proposed Rule 22.1)
    Proposed Chapter XXII includes new proposed definitions applicable 
to binary options in Rule 22.1. In particular, the terms ``binary 
option,'' ``exercise price,'' ``exercise settlement amount,'' 
``contract multiplier,'' and ``reporting authority'' would be defined. 
In addition, the term ``call binary option'' would be defined to mean 
an option that returns an exercise settlement amount if the settlement 
value of the underlying broad-based index is at or above the exercise 
price at expiration (i.e., in- or at-the-money). Also, the term ``put 
binary option'' is defined to mean an option that returns an exercise 
settlement amount if the settlement value of the underlying broad-based 
index is below the exercise price at expiration (i.e., in-the-money).
    Further, the term ``settlement value'' would be defined to mean the 
value of the underlying broad-based index that is used to determine 
whether a binary option is in, at, or out of the money. For a binary 
option on a broad-based index on which traditional options on the same 
broad-based index are a.m.-settled, the ``settlement value'' is the 
reported opening level of such index as derived from the prices of the 
underlying securities on such day and as reported by the reporting 
authority for the index. For a binary option on a broad-based index on 
which traditional options on the same broad-based index are p.m.-
settled, the ``settlement value'' is the reported closing level of such 
index as derived from the prices of the underlying securities on such 
day and as reported by the reporting authority for the index.
(2) Days and Hours of Business (Proposed Rule 22.2 and Amendment to 
Rule 6.1)
    Proposed Rule 22.2 and an amendment to Rule 6.1, Days and Hours of 
Business, would provide that transactions in binary options overlying 
any broad-based index may be effected during normal Exchange option 
trading hours on any business day for other options on the same broad-
based index.
(3) Designation of Binary Option Contracts and Maintenance Listing 
Standards (Proposed Rules 22.3 and 22.4)
    Proposed Rule 22.3, Designation of Binary Options Contracts, 
provides that the Exchange may from time to time approve for listing 
and trading on the Exchange binary options on a broad-based index which 
has been selected in accordance with Rule 24.2. Binary options would be 
a class separate from other options overlying the same broad-based 
index. Proposed Rule 22.3 also would provide that only binary option 
contracts approved by the Exchange and currently open for trading on 
the Exchange could be purchased or sold on the Exchange. Binary options 
dealt in on the Exchange would be designated as to expiration date, 
exercise price, exercise settlement value, contract multiplier, and 
underlying index. Binary options on a broad-based index for which 
traditional options on the same broad-based index are a.m.-settled 
would also be a.m.-settled, and binary options on a broad-based index 
for which traditional options on the same broad-based index are p.m.-
settled (i.e., S&P 100 Index (``OEX'')) would be p.m.-settled.
    To the extent possible, the Exchange would recognize and treat 
binary options like existing standardized options. Standardized systems 
for listing, trading, transmitting, clearing, and settling options, 
including systems used by the OCC, would be employed in connection with 
binary options. In addition, binary options would have a symbology 
based on the current system, so that symbols are created that represent 
the expiration date, exercise price, exercise settlement value, and 
underlying index.
    Proposed Rule 22.3 would provide that, after a particular binary 
option has been approved for listing and trading on the Exchange, the 
Exchange could open for trading series of options on that class. Binary 
option series could be designated to expire from one day up to 36 
months from the time that they are listed. The Exchange could add new 
series of options of the same class as provided for in Rule 24.9 and 
the related Interpretations and Policies. Additional series of the same 
binary option class could be opened for trading on the Exchange when 
the Exchange deems it necessary to maintain an orderly market or to 
meet customer demand. The opening of a new series of binary options on 
the Exchange would not affect any other series of options of the same 
class previously opened.
    Proposed Rule 22.4, Maintenance Listing Standards, would provide 
that the maintenance listing standards set forth in Rule 24.2 and the 
Interpretations and Policies thereunder would be applicable to binary 
options on broad-based indexes.
(4) Margin Requirements (Amendment to Rule 12.3)
    The Exchange is proposing to amend Rule 12.3, Margin Requirements, 
to include requirements applicable to binary options. Under the 
proposed requirements, for a Margin Account, no binary option carried 
for a customer shall be considered of any value for purposes of 
computing the margin required in the account of such customer. The 
initial and maintenance margin required on any binary option carried 
long in a customer's account is 100% of the purchase price of such 
binary option (i.e., the premium). In connection with a short position 
in binary options, the customer margin required is the exercise 
settlement amount. As for spreads, no margin is required on a binary 
call option (put option) carried short in a customer's account that is 
offset by a long binary call option (put option) for the same

[[Page 20987]]

underlying security or instrument that expires at the same time and has 
an exercise price that is less than (greater than) the exercise price 
of the short call (put). The long call (put) must be paid for in full. 
As for a straddle/combination, when a binary call option is carried 
short in a customer's account and there is also carried a short binary 
put option that expires at the same time and has an exercise price that 
is less than or equal to the exercise price of the short call, the 
initial and maintenance margin required is the exercise settlement 
amount applicable to one contract.
    For a cash account, a binary option carried short in a customer's 
account would be deemed a covered position, and eligible for the cash 
account, if either one of the following is held in the account at the 
time the option is written or is received into the account promptly 
thereafter: (1) Cash or cash equivalents equal to 100% of the exercise 
settlement amount; or (2) a long binary option of the same type (put or 
call) for the same underlying security or instrument that is paid for 
in full and expires at the same time, and has an exercise price that is 
less than the exercise price of the short in the case of a call or 
greater than the exercise price of the short in the case of a put; or 
(3) an escrow agreement. The escrow agreement must certify that the 
bank holds for the account of the customer as security for the 
agreement cash, cash equivalents, one or more qualified equity 
securities, or a combination thereof having an aggregate market value 
of not less than 100% of the exercise settlement amount, and that the 
bank would promptly pay the member organization the cash settlement 
amount in the event the account is assigned an exercise notice. The 
Exchange believes that these proposed levels are appropriate because 
risk exposure is limited with binary options and the proposed customer 
initial and maintenance margin would be equal to the maximum risk 
exposure.\5\
---------------------------------------------------------------------------

    \5\ In accordance with Rule 12.10, Margin Required is Minimum, 
the Exchange has the ability to determine at any time to impose 
higher margin requirements than those described above in respect of 
any binary option position when it deems such higher margin 
requirements are appropriate.
---------------------------------------------------------------------------

(5) Limitations of Liability of Exchange and of Reporting Authority 
(Proposed Rule 22.5)
    The Exchange proposes in Rule 22.5 to state expressly that Rule 
6.7, Exchange Liability, shall apply to binary options. Proposed Rule 
22.5 also would provide that the rule in CBOE's Index Options rules 
that disclaims liability on behalf of each reporting authority that is 
the source of values of any index underlying any class of index 
options--Rule 24.14--would be applicable with respect to reporting 
authorities for indexes that underlie binary options.
(6) Position Limits, Position Reporting Requirements, No Exercise 
Limits, and Other Restrictions (Proposed Rules 22.6 to 22.10)
    The Exchange is proposing a two-pronged approach to determine 
position limits for binary options. In determining compliance with Rule 
4.11, the Exchange proposes a fixed position limit of 15,000 contracts 
for binary options on a broad-based index for which traditional options 
on the same broad-based index have no position limit, provided that the 
exercise settlement amount is $10,000. For binary options that have an 
exercise settlement amount that is not equal to $10,000, the position 
limit would be 15,000 times the ratio of 10,000 to the exercise 
settlement amount (e.g., if the binary option exercise settlement 
amount is $1,000, then the position limit is 150,000 contracts. If the 
binary option exercise settlement amount is $12,000, then the position 
limit is 12,500 contracts).
    The Exchange proposed a formulaic position limit for binary options 
on a broad-based index for which traditional options on the same broad-
based index have a position limit. The formulaic position limit would 
be calculated in accordance with the following methodology: (1) 
Determine the Market Capitalization of the S&P 500 Index; (2) determine 
the Market Capitalization of the broad-based index underlying the 
binary option; and (3) calculate the Market Capitalization Ratio of the 
broad-based index underlying the binary option to the Market 
Capitalization of the S&P 500 Index. The position limit for binary 
options subject to a formulaic limit with an exercise settlement amount 
of $10,000 would be: (1) 10,000 contracts if the Market Capitalization 
Ratio is greater than or equal to 0.50; (2) 5,000 contracts if the 
Market Capitalization Ratio is less than 0.50 but greater than or equal 
to 0.25; and (3) 2,500 contracts if the Market Capitalization Ratio is 
less than 0.25 but greater than or equal to 0.10. The Exchange would 
seek Commission approval prior to establishing position limits for 
binary options on broad-based indexes that have a Market Capitalization 
Ratio that is less then 0.10. For binary options that have an exercise 
settlement amount that is not equal to $10,000, the position limit 
would be the ratio of 10,000 to the exercise settlement amount 
multiplied by the applicable formulaic limit.
    Proposed Rule 22.6 also would provide that positions in binary 
options on the same broad-based index that have different exercise 
settlement amounts would be aggregated. In determining compliance with 
the position limits set forth in proposed Rule 22.6, binary option 
contracts would not be aggregated with non-binary option contracts on 
the same or similar underlying security or broad-based index. In 
addition, binary option contracts on broad-based indexes would not be 
aggregated with non-binary option contracts on an underlying stock or 
stocks included within such broad-based index, and binary options on 
one broad-based index shall not be aggregated with binary options on 
any other broad-based index.
    For purposes of the position limits established under proposed Rule 
22.6, a long position in a binary put option and a short position in a 
binary call option would be considered to be on the same side of the 
market; and a short position in a binary put option and a long position 
in a binary call option would be considered to be on the same side of 
the market. Binary options would not be subject to the hedge exemption 
to the standard position limits found in Rule 4.11. Under proposed Rule 
22.6, the following qualified hedge exemption strategies and positions 
would be exempt from the established binary option position limits: (1) 
A binary option position ``hedged'' or ``covered'' by an appropriate 
amount of cash to meet the settlement obligation (e.g., $1,000 for a 
binary option with an exercise settlement amount of $1,000); (2) a 
binary option position ``hedged'' or ``covered'' by a sufficient amount 
of a related or similar security to meet the settlement obligation; or 
(3) a binary option position ``hedged'' or ``covered'' by a traditional 
option covering the same underlying broad-based index sufficient to 
meet the settlement obligation.
    Binary options would not be subject to exercise limits due to the 
fact that they are European-style options and would be automatically 
exercised at expiration if the settlement value of the underlying index 
is equal to or greater than the exercise price of a binary call option 
or less than the exercise price in the case of a binary put option. 
Proposed Rule 22.7 confirms this.
    Proposed Rule 22.8, Reports Related to Position Limits and 
Liquidation of Positions, would state that references in Rules 4.13, 
Reports Related to Position Limits, and 4.14, Liquidation of Positions, 
to Rule 4.11 in connection

[[Page 20988]]

with position limits would be deemed, in the case of binary options, to 
be to Rule 22.6. As such, in accordance with Rule 4.13(a), a position 
in binary options would have to be reported to the Exchange via the 
Large Option Positions Report when an account establishes an aggregate 
same side of the market position of 200 or more binary options. In 
computing reportable binary options under existing Rule 4.13: (1) 
Positions in binary options that have different exercise settlement 
amounts would be aggregated; (2) a position in a binary option would 
not be aggregated with a non-binary position in a option on the same or 
similar underlying security or broad-based index; (3) a position in a 
binary option on a broad-based index would not be aggregated with a 
position in a non-binary option on an underlying stock or stocks 
included within such broad-based index; and (4) a position in a binary 
option on one broad-based index would not be aggregated with a position 
in a binary option on any other broad-based index. The Exchange 
believes that the reporting requirements and the surveillance 
procedures for hedged positions would enable the Exchange to closely 
monitor sizable positions and corresponding hedges.
    Proposed Rule 22.9 would provide that binary options are not 
subject to Rule 4.16(b) and Interpretation and Policy .01 under Rule 
4.16; this is because Rule 4.16(b) is relevant only for American-style 
options and Interpretation and Policy .01 under Rule 4.16 is relevant 
only for options that are settled by delivery of an underlying 
security. Paragraph (a) of Rule 4.16, which provides the Exchange's 
Board with the power to impose restrictions on transactions in one or 
more series of options of any class dealt in on the Exchange, as the 
Board in its judgment determines advisable in the interests of 
maintaining a fair and orderly market or otherwise deems advisable in 
the public interest, is applicable to binary options.
(7) Determination of Exercise Price (Proposed Rule 22.10)
    The Exchange proposes in Rule 22.10 to provide that the 
determination of whether binary options are in, at, or out of the money 
at expiration would be a function of the settlement value of the 
underlying broad-based index in relation to the type of binary option 
(i.e., put or call) and the exercise price.
(8) Trading Mechanics for Binary Options (Proposed Rules 22.11 to 
22.16)
    The Exchange intends to trade binary options similar to the manner 
in which it trades other index options. Under the proposed rules, 
trading in binary options would be conducted in the following manner:
     Trading Rotations (Proposed Rule 22.11): Trading rotations 
generally would be conducted through use of the Hybrid Opening System 
(``HOSS''), which is described in existing Rule 6.2B. In addition, 
Rules 6.2, Trading Rotations, 6.2A, Rapid Opening System, and 24.13, 
Trading Rotations, would apply to binary options.
     Trading Halts and Suspension of Trading (Proposed Rule 
22.12): The trading halt procedures contained in existing Rules 6.3 and 
6.3B and 24.7 would apply to binary options.
     Premium Bids and Offers; Minimum Increments; Priority and 
Allocation (Proposed Rule 22.13): All bids and offers would be deemed 
to be for one contract unless a specific number of option contracts is 
expressed in the bid or offer. A bid or offer for more than one option 
contract which is not made all-or-none would be deemed to be for that 
amount or any lesser number of options contracts. An all-or-none bid or 
offer would be deemed to be made only for the amount stated. All bids 
and offers made for binary option contracts related to an underlying 
index would be governed by Rules 6.41, Meaning of Premium Bids and 
Offers; 6.42, Minimum Increments for Bids and Offers; 6.44, Bids and 
Offers in Relation to Units of Trading; 6.45, Priority of Bids and 
Offers--Allocation of Trades; 6.45B, Priority and Allocation of Trades 
in Index Options and Options on ETFs on the CBOE Hybrid System; and 
24.8, Meaning of Premium Bids and Offers, as applicable. The minimum 
price variation (``MPV'') would be established on a class-by-class 
basis by the Exchange and would not be less than $0.01. The rules of 
priority and order allocation procedures set forth in Rule 6.45A, 
Priority and Allocation of Equity Option Trades on the CBOE Hybrid 
System, would apply to binary options.\6\
---------------------------------------------------------------------------

    \6\ Proposed Rule 22.13 would conform to Article XIV, Section 3A 
of OCC's By-Laws with respect to adjustments of binary options. See 
Securities Exchange Act Release No. 56875 (November 30, 2007), 72 FR 
69274 (December 7, 2007) (SR-OCC-2007-08).
---------------------------------------------------------------------------

     Maximum Bid-Ask Differentials; Market-Maker Appointments & 
Obligations (Proposed Rule 22.14): Proposed Rule 22.14 would provide 
that a market maker is expected to bid and offer so as to create 
differences of no more than 25% of the designated exercise settlement 
value between the bid and offer for each binary option contract or 
$5.00, whichever amount is wider, except during the last trading day 
prior to the expiration where the maximum permissible price 
differential for binary options may be 50% or $5.00, whichever amount 
is wider. Proposed Rule 22.14 also would provide that the market maker 
appointment process for binary option classes would be the same as the 
appointments for other options, as set out in existing Rules 8.3, 
Appointment of Market-Makers; 8.4, Remote Market-Makers; 8.14, Index 
Hybrid Trading System Classes: Market-Maker Participants; 8.15, Lead 
Market-Makers and Supplemental Market-Makers in Non-Hybrid and Hybrid 
3.0 Classes; 8.15A, Lead Market-Makers in Hybrid Classes; and 8.95, 
Allocation of Securities and Location of Trading Crowds and DPMs.
     Automatic Exercise of Binary Option Contracts (Proposed 
Rule 22.15): Proposed Rule 22.15 would provide that a binary option 
would be automatically exercised at expiration if the settlement value 
of the underlying broad-based index is equal to or greater than the 
exercise price of a binary call option or less than the exercise price 
in the case of a binary put option. Rules 11.2 and 11.3 would not apply 
to binary options.
     FLEX Trading Rules (Proposed Rule 22.16): Proposed Rule 
22.16 would provide that, in addition to Hybrid, binary options would 
be eligible for trading as Flexible Exchange Options as provided for in 
Chapter XXIVA and XXIVB. For purposes of Rules 24A.4 and 24B.4, the 
applicable exercise settlement amount would be designated by the 
parties to the contract, the parties to the contract cannot designate 
an Exercise Style other than European-style, and the term ``index 
multiplier'' as used in those rules would refer to the ``contract 
multiplier'' as defined in Chapter XXII. Rules 24A.7 and 24B.7 would 
not apply to binary options and the position limit methodology set 
forth in Rule 22.6 would apply. Rules 24A.9 and 24B.9, regarding 
minimum quote width, would not apply to binary options and the minimum 
quote width set forth in Rule 22.14 would apply.
OCC Rule Filing; Options Disclosure Document
    The OCC has amended its By-Laws and Rules to accommodate the 
listing and trading of binary options.\7\ In addition, CBOE understands 
that the OCC has submitted to the Commission a proposed Supplement to 
the Options Disclosure Document (``ODD'') to accommodate binary options 
on board based indexes.
---------------------------------------------------------------------------

    \7\ See Securities Exchange Act Release No. 56875 (November 30, 
2007), 72 FR 69274 (December 7, 2007) (SR-OCC-2007-08).

Systems Capacity
    CBOE represents that it believes the Exchange and the Options Price 
Reporting Authority have the necessary systems capacity to handle the 
additional traffic associated with the listing and trading of binary 
options as proposed herein. CBOE does not anticipate that there would 
be any additional quote mitigation strategy necessary to accommodate 
the trading of binary options.
2. Statutory Basis
    The Exchange believes the proposed rule change is consistent with 
the Act and the rules and regulations under the Act applicable to a 
national securities exchange and, in particular, the requirements of 
Section 6(b) of the Act. Specifically, the Exchange believes the 
proposed rule change is consistent with the Section 6(b)(5) \8\ 
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,
