Rules of Cboe EDGX Exchange, Inc.

Rule 19.6 Series of Options Contracts Open for Trading

(c) Additional series of options of the same class may be opened for trading on EDGX Options when the Exchange deems it necessary to maintain an orderly market, to meet Customer demand or when the market price of the underlying stock moves more than five strike prices from the initial exercise price or prices. The opening of a new series of options shall not affect the series of options of the same class previously opened. New series of options on an individual stock may be added until the beginning of the month in which the options contract will expire. Due to unusual market conditions, the Exchange, in its discretion, may add a new series of options on an individual stock until the close of trading on the [five (5)] business day[s] prior to expiration.

The text of the proposed rule change is also available on the Exchange's website ( http://markets.cboe.com/us/options/regulation/rule_filings/edgx/ ), at the Exchange's Office of the Secretary, and at the Commission's Public Reference Room.

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 Statutory Basis for, the Proposed Rule Change

1. Purpose

The Exchange proposes to amend Rule 19.6(c) to allow for the addition of new series of options on an individual stock until the close of trading on the business day prior to expiration in unusual market conditions. This is a competitive proposed rule change based on filings submitted by the International Securities Exchange, LLC (“ISE”) and NASDAQ OMX BX (“BX”) to the Securities and Exchange Commission (“Commission”).

Currently, under Rule 19.6(c), when faced with unusual market conditions, the Exchange may add new series of options on an individual stock until five business days prior to expiration. In 2013, the Options Clearing Corporation (“OCC”) implemented a transition for standard option monthly expiration processing from Saturday to Friday. At this time, however, the Exchange did not list series of option contracts with Saturday or non-business day expiration, and accordingly, did not need to update its rules in line with the OCC initiative. Other exchanges amended their rules to reflect the OCC change, differentiating between Friday and Saturday or non-business day expirations during the transitional period. Also at this time, other exchanges specified that additional series of individual stock options may be added during unusual market conditions until the close of trading on the business day prior to expiration in the case of an option contract expiring on a business day (i.e., Thursday for Friday expirations), or, in the case of an option contract expiring on a day that is not a business day until the close of trading on the second business day prior to expiration (i.e., Thursday for Saturday expirations). The Exchange thus proposes to amend Rule 19.6(c) to allow specifically for the addition of new series of options on an individual stock until the close of trading on the business day prior to expiration in unusual market conditions in line with other exchanges' timing requirements for listing series of options prior to expiration.

The Exchange seeks to introduce this proposed change to Rule 19.6(c) to create a uniform expiration date across exchanges for standard options on listed classes. The Exchange believes that keeping its rules consistent with those of the industry will protect all participants in the market by eliminating confusion, reducing the likelihood of rule violations due to discrepant industry rules, and by allowing for a more orderly market. In addition, the Exchange believes that keeping the proposed rule consistent with other exchange rules will foster better cooperation and coordination with persons engaged in regulating clearing, settling, processing information with respect to, and facilitating transactions in securities by aligning a pivotal part of the options processing to be consistent industry-wide

2. Statutory Basis

The Exchange believes the proposed rule change is consistent with the Securities Exchange Act of 1934 (the “Act”) and the rules and regulations thereunder applicable to the 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) requirements that the rules of an exchange be 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 regulating, clearing, settling, processing information with respect to, and facilitating transactions in securities, to 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. Additionally, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) requirement that the rules of an exchange not be designed to permit unfair discrimination between customers, issuers, brokers, or dealers.

In particular, the Exchange believes that keeping its rules consistent with those of other exchanges and industry practices will protect all participants in the market by eliminating confusion, thus, preventing investor vulnerability to violating different exchange rules. Additionally, the proposed change will foster cooperation and coordination with persons engaged in regulating clearing, settling, processing information with respect to, and facilitating transactions in securities by aligning the timing of series of options listing during unusual market conditions to be consistent industry-wide. Further, as the industry-wide transition from Saturday (and non-business day) expiration dates to Friday (or other business days) expiration dates was successful, the Exchange believes the proposed rule change will remove a discrepant industry impediment and allow for a more orderly market by permitting all options markets, including the clearing agencies, to have the same expiration date for series of options listed during periods of unusual market conditions. The proposed rule change also perfects the mechanism of a free and open market by allowing for the Exchange to list additional series of options on an individual stock closer to expiration during unusual market conditions thus better aligning the listed series of options with prices near expiration. Finally, the proposed rule change does not permit unfair discrimination between any Members as it is applied to all Members equally.

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

The Exchange does not believe that the proposed rule change will impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act. In this regard and as indicated above, the Exchange notes that the rule change is being proposed as a competitive response to proposals previously filed by ISE and BX with the Commission. The proposed rule change will allow for the Exchange to list additional series of options on an individual stock closer to expiration during unusual market conditions thus better aligning the listed series of options with prices near expiration.

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

The Exchange neither solicited nor received comments on the proposed rule change.

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

Because the foregoing 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 for 30 days from the date on which it was filed, or such shorter time as the Commission may designate, it has become effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6) thereunder.

A proposed rule change filed pursuant to Rule 19b-4(f)(6) under the Act normally does not become operative for 30 days after the date of its filing. However, Rule 19b-4(f)(6)(iii) permits the Commission to designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has asked the Commission to waive the 30-day operative delay. The Exchange believes that waiver of the operative delay is consistent with the protection of investors and the public interest because it is substantially similar in all material respects to prior filings from ISE and BX, and does not raise any new or novel issues. For this reason, the Commission believes that waiver of the 30-day operative delay is consistent with the protection of investors and the public interest. Therefore, the Commission hereby waives the operative delay and designates the proposal as operative upon filing.

At any time within 60 days of the filing of the 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 to determine whether the proposed rule change should be approved or disapproved.
