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 Exchange 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. The Exchange 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 the Statutory Basis for, the Proposed Rule Change

1. Purpose

The Exchange proposes: (i) To adopt Section 3(d) to provide for how BX will treat options orders in response to the Regulation NMS Plan to Address Extraordinary Market Volatility (the “Plan”), which is applicable to all NMS stocks, as defined in Regulation NMS Rule 600(b)(47); and (ii) to adopt Section 3(e) to codify that BX shall halt trading in all options when the equities markets initiate a market-wide trading halt due to extraordinary market volatility. The Exchange proposes to adopt Section 3(d) for a pilot period that coincides with the pilot period for the Plan.

Background

Since May 6, 2010, when the markets experienced excessive volatility in an abbreviated time period, i.e., the “flash crash,” the equities exchanges and the Financial Industry Regulatory Authority (“FINRA”) have implemented market-wide measures designed to restore investor confidence by reducing the potential for excessive market volatility. The measures adopted include pilot plans for stock-by-stock trading pauses, related changes to the equities market clearly erroneous execution rules, and more stringent equities market maker quoting requirements. On May 31, 2012, the Commission approved the Plan, as amended, on a one-year pilot basis. In addition, the Commission approved changes to the equities market-wide circuit breaker rules on a pilot basis to coincide with the pilot period for the Plan.

The Plan is designed to prevent trades in individual NMS stocks from occurring outside of specified Price Bands. As described more fully below, the requirements of the Plan are coupled with Trading Pauses to accommodate more fundamental price moves (as opposed to erroneous trades or momentary gaps in liquidity). All trading centers in NMS stocks, including both those operated by Participants and those operated by members of Participants, are required to establish, maintain, and enforce written policies and procedures that are reasonably designed to comply with the requirements specified in the Plan.

As set forth in more detail in the Plan, Price Bands consisting of a Lower Price Band and an Upper Price Band for each NMS Stock are calculated by the Processors. When the National Best Bid (Offer) is below (above) the Lower (Upper) Price Band, the Processors shall disseminate such National Best Bid (Offer) with an appropriate flag identifying it as unexecutable. When the National Best Bid (Offer) is equal to the Upper (Lower) Price Band, the Processors shall distribute such National Best Bid (Offer) with an appropriate flag identifying it as a Limit State Quotation. All trading centers in NMS stocks must maintain written policies and procedures that are reasonably designed to prevent the display of offers below the Lower Price Band and bids above the Upper Price Band for NMS stocks. Notwithstanding this requirement, the Processor shall display an offer below the Lower Price Band or a bid above the Upper Price Band, but with a flag that it is non-executable. Such bids or offers shall not be included in the National Best Bid or National Best Offer calculations. Trading in an NMS stock immediately enters a Limit State if the National Best Offer (Bid) equals but does not cross the Lower (Upper) Price Band. Trading for an NMS stock exits a Limit State if, within 15 seconds of entering the Limit State, all Limit State Quotations were executed or canceled in their entirety. If the market does not exit a Limit State within 15 seconds, then the Primary Listing Exchange would declare a five-minute trading pause pursuant to Section VII of the Plan, which would be applicable to all markets trading the security. In addition, the Plan defines a Straddle State as when the National Best Bid (Offer) is below (above) the Lower (Upper) Price Band and the NMS stock is not in a Limit State. For example, assume the Lower Price Band for an NMS Stock is $9.50 and the Upper Price Band is $10.50, such NMS stock would be in a Straddle State if the National Best Bid were below $9.50, and therefore unexecutable, and the National Best Offer were above $9.50 (including a National Best Offer that could be above $10.50). If an NMS stock is in a Straddle State and trading in that stock deviates from normal trading characteristics, the Primary Listing Exchange may declare a trading pause for that NMS stock if such Trading Pause would support the Plan's goal to address extraordinary market volatility.

Proposed Section 3(d)

Openings

The Exchange proposes to adopt new Section 3(d) to provide for how BX shall treat orders and quotes in options overlying NMS stocks when the Plan is in effect. First, the Exchange proposes to adopt new subparagraph (i) to provide for how the Exchange shall treat the opening. The opening in an option will not commence in the event that the underlying NMS stock is open, but has entered into a Limit State or Straddle State. If this occurs, the opening will only commence and complete if the underlying NMS stock stays out of a Limit or Straddle State. Accordingly, new Section 3(d)(i) will provide that the Exchange will not open an affected option. As a result, if an opening process is occurring, it will cease and then start the opening process from the beginning once the Limit State or Straddle State is no longer occurring.

Orders

Second, the Exchange proposes to adopt provisions regarding the treatment of certain orders if the underlying NMS stock is in a Limit State or Straddle State. Whenever an NMS stock is in a Limit State or Straddle State, trading continues; however, there will not be a reliable price for a security to serve as a benchmark for the price of the option. For example, if the underlying NMS stock is in a Limit State, while trading in that stock continues, by being in a Limit State, there will be either cancellations or executions at that price, and if the Limit State is not resolved in 15 seconds, the NMS Stock will enter a Trading Pause. If an NMS stock is in a Straddle State, that means that there is either a National Best Bid or National Best Offer that is non-executable, which could result in limited price discovery in the underlying NMS stock. In addition to the lack of a reliable underlying reference price, the Exchange is concerned about the width of the markets and quality of the execution for market participants during a Limit State or Straddle State. While the Exchange recognizes the importance of continued trading in options overlying NMS stocks during Limit States and Straddle States, the Exchange believes that certain types of orders increase the risk of errors and poor executions and therefore should not be allowed during these times when there may not be a reliable underlying reference price, there may be a wide bid/ask quotation differential, and there may be lower trading liquidity in the options markets.

Therefore, the Exchange proposes that if an NMS stock is in a Limit State or Straddle State, once the option has opened for trading, the Exchange shall reject all incoming Market Orders, as defined in Chapter VI, Section 1, and shall notify Participants of the reason for such rejection. Market Orders residing in the System will be handled in the normal fashion under Exchange rules. The Exchange believes that adding certainty to the treatment of Market Orders when the underlying NMS stock is in these situations should encourage market participants to continue to provide liquidity to the Exchange and thus promote a fair and orderly market.

Proposed Section (e)

The Exchange also proposes to adopt Section (e), which provides that the Exchange shall halt trading in all options whenever the equities markets initiate a market-wide trading halt commonly known as a circuit breaker in response to extraordinary market conditions. Although Section 3 currently address a variety of situations involving halts, pauses and suspensions, the Exchange has determined to adopt a very specific rule to deal with circuit breaker-related halts. The Exchange believes that this rule can be adopted on a permanent basis, even though the equities circuit breakers are subject to a pilot program, because the proposed rule refers to such circuit breakers generally.

2. Statutory Basis

BX believes that its proposal is consistent with Section 6(b) of the Act in general, and furthers the objectives of Section 6(b)(5) of the Act in particular, in that it is designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in facilitating transactions in securities, and to remove impediments to and perfect the mechanisms of a free and open market and a national market system, and, in general, to protect investors and the public interest, because it should provide certainty about how options orders and trades will be handled during periods of extraordinary volatility in the underlying security. Specifically, under the proposal, market participants will be able to continue to trade options overlying securities that are in a Limit State or Straddle State, while addressing specific order types that are subject to added risks during such periods. The Exchange believes that the rejection of options Market Orders should help to prevent executions that might occur at prices that have not been reliably formed, which should, in turn, protect, in particular, retail investors from executions of un-priced orders during times of significant volatility.

Accordingly, the Exchange believes that the proposed rule change is consistent with these requirements in that it should reduce the negative impacts of sudden, unanticipated volatility in individual options, and serve to preserve an orderly market in a transparent and uniform manner, enhance the price-discovery process, increase overall market confidence, and promote fair and orderly markets and the protection of investors.

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

The Exchange does not believe that the proposed rule change will result in any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act, as amended. Specifically, the proposal does not impose an intra-market burden on competition, because it will apply to all Options Participants. Nor will the proposal impose a burden on competition among the options exchanges, because, in addition to the vigorous competition for order flow among the options exchanges, the proposal addresses a regulatory situation common to all options exchanges. To the extent that market participants disagree with the particular approach taken by the Exchange herein, market participants can easily and readily direct order flow to competing venues. The Exchange believes this proposal for how to treat options openings and orders will not impose a burden on competition and will help provide certainty during periods of extraordinary volatility in an NMS stock.

C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others

No written comments were either solicited or received.

III. Date of Effectiveness of the Proposed Rule Change and Timing for Commission Action

The Exchange has filed the proposed rule change pursuant to Section 19(b)(3)(A)(iii) of the Act and Rule 19b-4(f)(6) thereunder. Because the proposed rule change does not: (i) Significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; and (iii) become operative prior to 30 days from the date on which it was filed, or such shorter time as the Commission may designate, if consistent with the protection of investors and the public interest, the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6)(iii) thereunder.

At any time within 60 days of the filing of such proposed rule change, the Commission summarily may temporarily suspend such rule change if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection of investors, or otherwise in furtherance of the purposes of the Act. If the Commission takes such action, the Commission shall institute proceedings under Section 19(b)(2)(B) of the Act to determine whether the proposed rule change should be approved or disapproved.
