November 25, 2011 Volume RB22, Number 47 The Bylaws and Rules of Chicago Board Options Exchange, Incorporated ( Exchange ), in certain specific instances, require the Exchange to provide notice to Trading Permit Holders. The weekly Regulatory Bulletin is delivered to all effective Trading Permit Holders to satisfy this requirement. Copyright 2011 Chicago Board Options Exchange, Incorporated. REGULATORY CIRCULARS Regulatory Circular RG11-139 To: From: Trading Permit Holders Legal & Regulatory Services Divisions Date: November 18, 2011 RE: Prefix Usage for SPX Combination ( Combo ) Orders The purpose of this Regulatory Circular is to remind SPX traders that for all SPX Combo Orders that are transacted, SPX traders are required to designate each of the component series of the order as "CMBO" on all electronic execution systems, such as PAR Terminals, when submitting the trade to the Exchange for price reporting. 1 On PAR Terminals this is accomplished by selecting the CMBO ENDORSED tab on the PAR Terminal. 1. When an SPX Combo Order is transacted, the prices of the component series must be reported to the trading floor and to OPRA using the prefix CMBO. The CMBO prefix acts as notice to the public that the reported prices are part of an SPX Combo Order and helps avoid investor confusion regarding out-of-range SPX prices. 2. As required by Rule 24.20, a Trading Permit Holder must be holding an SPX Combo Order when it is originally quoted. Orders must also be systematized in accordance with Rule 6.24 (the COATS rule). The Regulatory Services Division will monitor trading activity for compliance with Rule 24.20. Among other things, executions not meeting the Rule 24.20 requirements may be considered violations of the SPX limit book and/or displayed market priority. For additional information, please refer to Rule 24.20 and Regulatory Circular RG07-06. 1 An SPX Combo Order is defined in Rule 24.20 as an order to purchase or sell SPX options and the offsetting number of SPX combinations defined by the delta. (An SPX combination is a long (short) SPX call and a short (long) SPX put having the same expiration date and strike price). The delta is defined as the positive (negative) number of SPX combinations that must be sold (bought) to establish a market neutral hedge with an SPX option position. See Regulatory Circular RG07-06 for an explanation of Rule 24.20. November 25, 2011 Volume RG22, Number 47 1

Questions regarding the PAR Combo Endorsed feature may be referred to Jeff Short at 786-8410 or Monica Wiedlin-Torres at 786-7368. Questions concerning this circular may be directed to the Regulatory Interpretations and Guidance Line at 312-786-8141. Regulatory Circular RG11-141 DATE: November 18, 2011 TO: Trading Permit Holders FROM: Trading Operations RE: Operational Systems Settings Effective November 21, 2011, CBOE will adjust two operational systems settings in all classes as follows: Market orders entered when the NBBO at time of receipt is not within an acceptable price range will route to PAR, or at the entry firm s discretion, to the entry firm s booth. The acceptable price range will be based on the table below: Bid Price Acceptable Price Range 0.00 1.99 1.00 2.00 5.00 1.60 5.01 10.00 2.00 10.01 20.00 3.20 20.01 50.00 4.00 50.01 100.00 8.00 100.01 300.00 10.00 > =300.01 16.00 Additionally, series will not open if the opening price is not within an acceptable price range. The calculation for the acceptable price range will be the midpoint of the highest quote bid and lowest quote offer plus/minus half of the Opening Exchange Prescribed Width (OEPW), and where HALO is active, the NBBO if any, whichever is better. The OEPW will be based on the table below: Bid Price Opening Exchange Prescribed Width 0.00 1.99 0.50 2.00 5.00 0.80 5.01 10.00 1.00 10.01 20.00 1.60 20.01 50.00 2.00 50.01 100.00 4.00 100.01 300.00 5.00 > =300.01 8.00 Questions regarding this circular may be directed to: Doreen Scholla 312-786-7529, schollad@cboe.com; or CBOE Help Desk at (866)728-2263 or helpdesk@cboe.com November 25, 2011 Volume RG22, Number 47 2

Regulatory Circular RG11-142 To: Floor Brokers From: Regulatory Services Division Date: November 21, 2011 Re: Communication with Solicited Parties Floor-Brokers should take steps to prevent miscommunication with a solicited party; either verbally or through IM s and/or chats, to ensure the solicited party has a clear understanding of the status of an order. Ambiguous language may give the solicited party the perception that an order has been disclosed to the trading crowd, when in fact it has not. Examples of ambiguous language include: Going to trade now Can get you (x) total contracts You ll be on the order, going to trade soon Such language may mislead the solicited party, and unintentionally result in their pre-facilitating and/or front-running of the order, leading to violations of, but not necessarily limited to, Exchange Rules 4.1 and/or 6.9(e). 1 Floor-Brokers are advised to use clear language so that the solicited party understands the current status of an unexecuted order brought to the trading floor. Examples of clear communications prior to or following execution of an order are: The order has not reached the trading crowd yet, I will inform you when the order is in the trading crowd. The order is in the trading crowd. The order has been disclosed to the crowd. You have been filled on (x) total contracts. Questions regarding the topics in this circular may be directed to the Regulatory Interpretations and Guidance Line at (312)786-8141. 1 See Regulatory Circular 00-67 November 25, 2011 Volume RG22, Number 47 3

Regulatory Circular RG11-143 To: Trading Permit Holders From: Trading Operations Date: November 23, 2011 Re: Establishing New Series in FLEX Options This circular is being issued to advise Trading Permit Holders that the FLEX Option trading rules have recently been amended to provide that a new FLEX Options series may be established on any business day prior to its expiration date, with a maximum term of 15 years. (Previously, the rules provided that a new FLEX Equity Option series could be established any business day prior to its expiration date. However, the rules previously did not clearly address the applicability of any such new series add provision to other types of FLEX Options. The rule change makes it clear that the same new series add provision applies to all FLEX Options.) For information on the new series add provision as well as other FLEX term and trading requirements, please refer to Rule 24B.4, Chapter XXIVB of the Rules, and Rule Filing SR- CBOE-2011-098, which are available at www.cboe.org/legal.

Regulatory Circular RG11-144 To: Trading Permit Holders From: Finance and Administration Date: November 23, 2011 Re: Floor Broker Workstation (FBW) Market Access Controls Window The Chicago Board Options Exchange, Inc. (CBOE) has added to the functionality of the Floor Broker Workstations (FBW) by providing a new Market Access Controls Window, an optional feature of FBW available to each CBOE Trading Permit Holder that requests the feature. The Market Access Controls Window displays, for each grouping of FBW users within a CBOE Trading Permit Holder firm, values for the following access-based controls: Per Order Controls, which include values for (a) quantity of contracts per order, (b) premium amount per order, (c) number of identical orders, and (d) frequency of order entry (count and timeframe). Aggregate Controls, which include actual and predictive values for (1) premium amount per day, (2) quantity of contracts per day, and (3) the number of orders with a status of working. The FBW Market Access Controls Window fee is $100 per month per login ID, with a cap of $2,000 per month for any Trading Permit Holder. Therefore, any Trading Permit Holder that requests access to the FBW Market Access Controls Window for more than twenty login IDs will not be required to pay more than $2,000 per month for such access. The monthly fee will be effective December 1, 2011. November 25, 2011 Volume RG22, Number 47 4

The rule change increased this to 30 series per class with 20 initial series being permitted and 10 additional series being permitted if market conditions warrant. Any questions regarding the rule change may be directed to Jenny Klebes, Legal Division, at 312-786-7466. The rule text is shown below and the rule filing is available at http://www.cboe.com/publish/rulefilingssec/sr-cboe-2011-086.pdf. Rule 5.5 Series of Option Contracts Open for Trading RULE 5.5.

Similarly, if the Exchange is not open for business on the Friday of the following business week, the Short Term Option Expiration Date will be the first business day immediately prior to that Friday. Regarding Short Term Option Series: (1) Classes. The Exchange may select up to fifteen currently listed option classes on which Short Term Option Series may be opened on any Short Term Option Opening Date. In addition to the fifteen-option class restriction, the Exchange also may list Short Term Option Series on any option classes that are selected by other securities exchanges that employ a similar program under their respective rules. For each option class eligible for participation in the Short Term Option Series Program, the Exchange may open up to [twenty] 30 Short Term Option Series for each expiration date in that class. (2) Expiration.

The strike price of each Short Term Option Series will be fixed at a price per share, with approximately the same number of strike prices being opened above and below the value of the underlying security at about the time that the Short Term Option Series are initially opened for trading on the Exchange (e.g., November 25, 2011 Volume RG22, Number 47 6

if seven series are initially opened, there will be at least three strike prices above and three strike prices below the value of the underlying security). Any strike prices listed by the Exchange shall be within thirty percent (30%) above or below the closing price of the underlying security from the preceding day. (4) Additional Series. [If the Exchange opens less than twenty Short Term Option Series for a Short Term Option Expiration Date, additional series may be opened for trading on the Exchange] The Exchange may open up to 10 additional series for each option class that participates in the Short Term Option Series Program when the Exchange deems it necessary to maintain an orderly market, to meet customer demand or when the market price of the underlying security moves substantially from the exercise price or prices of the series already opened. Any additional strike prices listed by the Exchange shall be within thirty percent (30%) above or below the current price of the underlying security. The Exchange may also open additional strike prices of Short Term Option Series that are more than 30% above or below the current price of the underlying security provided that demonstrated customer interest exists for such series, as expressed by institutional, corporate or individual customers or their brokers. Market-Makers trading for their own account shall not be considered when determining customer interest under this provision. The opening of the new Short Term Option Series shall not affect the series of options of the same class previously opened. (5) Strike Interval. The interval between strike prices on Short Term Option Series shall be the same as the strike prices for series in that same option class that expire in accordance with the normal monthly expiration cycle.

Similarly, if the Exchange is not open for business on the Friday of the following business week, the Short Term Option Expiration Date will be the first business day immediately prior to that Friday. Regarding Short Term Option Series: (i) Classes.

For each index option class eligible for participation in the Short Term Option Series Program, the November 25, 2011 Volume RG22, Number 47 7

Exchange may open up to [twenty] 30 Short Term Option Series on index options for each expiration date in that class. (ii) Expiration.

(iii) Initial Series. The Exchange may open up to 20 initial series for each option class that participates in the Short Term Options Series Program. The strike price of each Short Term Option Series will be fixed at a price per share, with approximately the same number of strike prices being opened above and below the calculated value of the underlying index at about the time that the Short Term Option Series are initially opened for trading on the Exchange ( e.g., if seven series are initially opened, there will be at least three strike prices above and three strike prices below the value of the underlying security or calculated index value). Any strike prices listed by the Exchange shall be within thirty percent (30%) above or below the current value of the underlying index. (iv) Additional Series. [If the Exchange has opened less than twenty Short Term Option Series for a Short Term Option Expiration Date, additional series may be opened for trading on the Exchange] The Exchange may open up to 10 additional series for each open class that participates in the Short Term Option Series Program when the Exchange deems it necessary to maintain an orderly market, to meet customer demand or when the current value of the underlying index moves substantially from the exercise price or prices of the series already opened. Any additional strike prices listed by the Exchange shall be within thirty percent (30%) above or below the current value of the underlying index. The Exchange may also open additional strike prices of Short Term Option Series that are more than 30% above or below the current value of the underlying index provided that demonstrated customer interest exists for such series, as expressed by institutional, corporate or individual customers or their brokers. Market- Makers trading for their own account shall not be considered when determining customer interest under this provision.
