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 its Fees Schedule to clarify its fees for Certification Logical Port fees.

By way of background, the Exchange offers a variety of logical ports, which provide users with the ability within the Exchange's System to accomplish a specific function through a connection, such as order entry, data receipt or access to information. Specifically, the Exchange offers Logical Ports, Purge Ports, Multicast PITCH GRP Ports and Multicast PITCH Spin Server Ports. For each type of the aforementioned logical ports that is used in the production environment, the Exchange also offers corresponding ports which provide Members and non-Members access to the Exchange's certification environment to test proprietary systems and applications ( i.e., “Certification Logical Ports”). The certification environment facilitates testing using replicas of the Exchange's production environment process configurations which provide for a robust and realistic testing experience. For example, the certification environment allows unlimited firm-level testing of order types, order entry, order management, order throughput, acknowledgements, risk settings, mass cancelations, and purge requests. The Exchange currently provides free of charge one Certification Logical Port per port type offered in the production environment ( i.e., Logical Ports, Purge, Multicast PITCH GRP, and Multicast PITCH Spin Server Ports) and a monthly fee of $250 per Certification Logical Port for any additional Certification Logical Ports.

The Exchange proposes to make clear in the notes section under the Logical Port Fees section of the Fees Schedule that the Certification Logical Port fees only apply if the corresponding logical port type is also in the production environment. For example, if the Exchange intends to adopt a new port type that has not yet been launched in the live production environment, any certification port for that port type will be free until such time that the proposed new port is in the production environment. Once any new logical port type is in the live production environment, Members and Non-Members will only be entitled to one free certification logical port for that port type, and any additional certifications ports of that type will be assessed the regular monthly $250 per port charge.

The Exchange notes that purchasing additional Certification Logical Ports continues to be voluntary and not required in order to participate in the production environment, including live production trading on the Exchange. Additionally, Members and non-Members are not required to purchase any particular production logical port in order to receive a corresponding Certification Logical Port free of charge. Further, the Exchange also notes that other exchanges similarly assess fees related to their respective testing environments.

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 section 6(b)(4) of the Act, which requires that Exchange rules provide for the equitable allocation of reasonable dues, fees, and other charges among its Members and other persons using its facilities.

As noted above, the Exchange's certification environment provides a robust and realistic testing experience using a replica of the Exchange's production environment process configurations. This environment enables market participants to manage risk more effectively through testing software development changes in certification prior to implementing them in the live trading environment, thereby reducing the likelihood of a potentially disruptive system failure in the live trading environment, which has the potential to affect all market participants. The Exchange believes this is especially true when testing a new port type that has not yet launched in the production environment. As such, the Exchange believes it's reasonable to only assess the Certification Logical Port fee to ports that are also available in the production environment as to not discourage the testing of new ports ahead of any respective launch date. The Exchange also believes applying the Certification Logical Port fee is reasonable once such ports are available in the production environment because while such ports will no longer be completely free, Members and non-Members will continue to be entitled to receive free of charge one Certification Logical Port for such port. The Exchange continues to believe one Certification Logical Port per logical port type will be sufficient for most Members or Non-Members and indeed anticipates that the majority of users will not purchase additional Certification Logical Ports. For those who wish to obtain additional Certification Logical Ports based on their respective business needs, such as those wishing to test across various diverse systems within their own infrastructure, they are able to do so for a modest fee. Indeed, the decision to purchase additional ports is optional and no market participant is required or under any regulatory obligation to purchase excess Certification Logical Ports in order to access the Exchange's certification environment. Further, the Exchange has observed that market participants that do choose to purchase additional Certification Logical Ports maintain significantly fewer Certification Logical Ports as compared to the corresponding logical ports they use in the production in environment.

The Exchange believes the proposal to make clear that the Certification Logical Port fee applies only to logical ports that are in the production environment is equitable and not unfairly discriminatory because it applies uniformly to all market participants that choose to obtain additional Certification Logical Ports and all market participants will have further clarity as to which certification ports are subject to the current fee. The Exchange also believes the proposed change is reasonable, equitable and not unfairly discriminatory because it is designed to encourage market participants to avail themselves of Certification Logical Ports for new port types before they launch to become acclimated with the new connectivity offering ahead of going live in the trading environment. The Exchange believes the proposal to add this language to the notes section in the Fees Schedule also provides clarity in the rules as to when the Certification Logical Port fee applies and reduces potential confusion.

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 intramarket or intermarket competition that is not necessary or appropriate in furtherance of the purposes of the Act. The Exchange does not believe that the proposed rule change will impose any burden on intramarket competition because as the proposed change applies uniformly to all market participants. Additionally, the Exchange does not believe that the proposed fee creates an undue burden on competition because the Exchange will continue to offer free of charge one Certification Logical Port per each logical port type once offered in the production environment. Also as discussed, the purchase of additional ports is optional and based on the business needs of each market participant. Moreover, such market participants will continue to benefit from access to the certification environment, which the Exchange believes provides a robust and realistic testing experience via a replica of the production environment, which may be especially critical during the time leading up to the launch of a new port type in the production environment.

The Exchange does not believe that the proposed rule changes will impose any burden on intermarket competition that is not necessary or appropriate in furtherance of the purposes of the Act. Particularly, the proposed change applies only to the Exchange's certification environment. Additionally, the Exchange notes that it operates in a highly competitive market. Members have numerous alternative venues that they may participate on and direct their order flow, including 15 other equities exchanges, as well as a number of alternative trading systems and other off-exchange venues, where competitive products are available for trading. Indeed, participants can readily choose to send their orders to other exchanges, and, additionally off-exchange venues, if they deem overall fee levels at those other venues to be more favorable. Moreover, the Commission has repeatedly expressed its preference for competition over regulatory intervention in determining prices, products, and services in the securities markets. Specifically, in Regulation NMS, the Commission highlighted the importance of market forces in determining prices and SRO revenues and, also, recognized that current regulation of the market system “has been remarkably successful in promoting market competition in its broader forms that are most important to investors and listed companies.” The fact that this market is competitive has also long been recognized by the courts. In NetCoalition v. Securities and Exchange Commission, the D.C. Circuit stated as follows: “[n]o one disputes that competition for order flow is `fierce.' . . . As the SEC explained, `[i]n the U.S. national market system, buyers and sellers of securities, and the broker-dealers that act as their order-routing agents, have a wide range of choices of where to route orders for execution'; [and] `no exchange can afford to take its market share percentages for granted' because `no exchange possesses a monopoly, regulatory or otherwise, in the execution of order flow from broker dealers'. . . .”. Accordingly, the Exchange does not believe its proposed fee change imposes any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act.

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