On June 26, 2018, New York Stock Exchange LLC (“Exchange” or “NYSE”) filed with the Securities and Exchange Commission (“Commission”) pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) 
and Rule 19b-4 thereunder,
a proposed rule change to require certain member organizations to participate in scheduled market-wide circuit breaker testing. On July 5, 2018, the Exchange filed Amendment No. 1 to the proposed rule change, which supersedes the original filing in its entirety.
The proposed rule change, as amended by Amendment No. 1, was published for comment in the Federal Register on July 11, 2018.
The Commission has received no comment letters on the proposed rule change. This order approves the proposed rule change.
II. Description of the Proposed Rule Change
The Exchange proposes to amend NYSE Rule 49 to require certain member organizations to participate in scheduled Market-Wide Circuit Breaker (“MWCB”) testing.
The Securities Information Processors (“SIPs”) for the U.S. equity markets have established a quarterly MWCB testing schedule.
On the scheduled dates, the Consolidated Tape Association Plan (“CTA Plan”) and the Consolidated Quotation Plan (“CQ” Plan”) (collectively “the CTA/CQ Plans”),
along with the Nasdaq/UTP Plan,
conduct MWCB testing that allows market participants across the securities industry to test their ability to receive messages associated with MWCBs, including decline status, halt, and resume messages. Market participants are also able to participate in testing of re-opening auctions following market-wide circuit breaker halts.
The Exchange states that quarterly MWCB testing is critical to ensure that securities markets halt trading and subsequently re-open in a manner consistent with the MWCB rules.
To that end, the Exchange states that certain member organizations should be required to participate in scheduled MWCB tests. The proposed rule would provide the Exchange with authority to require participation by certain member organizations in industry-wide tests to validate that their processing in the event of MWCB is as expected within their systems.
The Exchange also proposes new Rule 49(c)(1), which would provide that each member organization notified of its obligation to participate in mandatory testing pursuant to standards established under paragraphs (b)(1) and (3) of Rule 49 
would also be required to participate in scheduled MWCB testing in the manner and frequency specified by the Exchange. The Exchange proposes that future SCI Notices would also include notification to member organizations of their obligation to participate in a scheduled MWCB test.
Finally, proposed Rule 49(c)(2) would provide that member organizations not required to participate in a scheduled MWCB test pursuant to standards established in paragraphs (b)(1) and (3) of Rule 49 would be permitted to participate in a scheduled MWCB test.
The Exchange proposes to implement the proposed rule change at the same time that the Exchange notifies member organizations of required participation in the 2019 Regulation SCI industry test.
The 2019 SCI Notice would identify the member organizations that would be required to participate in scheduled MWCB testing. Member organizations notified in the 2019 SCI Notice of their obligation to participate in a scheduled MWCB test would be required to participate in that test on at least one of the testing dates established by the SIPs.

III. Discussion and Commission's Findings
After careful review, the Commission finds that the proposed rule change, as modified by Amendment No. 1, is consistent with the requirements of the Act and the rules and regulations thereunder applicable to a national securities exchange.
In particular, the Commission finds that the proposed rule change, as modified by Amendment No. 1, is consistent with Section 6(b)(5) of the Act,
which requires, among other things, that the rules of a national securities 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 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, and that the rules not be designed to permit unfair discrimination between customers, issuers, brokers, or dealers. The Commission also finds that the proposed rule change, as modified by Amendment No. 1, is consistent with Section 6(b)(8) of the Act,
which requires that the rules of an exchange not impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act. As indicated above, the Commission has received no comment letters addressing the proposed rule change.
The Commission believes that amending NYSE Rule 49 to require certain member organizations to participate in scheduled MWCB testing would enable the Exchange, participating member organizations, and others to assess the readiness of participating member organizations to respond in the event of unanticipated market volatility. Member organizations required to participate in MWCB testing pursuant to the proposal would be designated as such using the same standards used by the Exchange in determining which member organizations are subject to mandatory Regulation SCI testing. Because these member organizations have been designated by the Exchange as essential to the maintenance of a fair and orderly market, their demonstrated ability to halt and subsequently re-open trading in a manner consistent with the MWCB rules should contribute to the fairness and orderliness of the market for the benefit of all market participants. The Commission therefore believes that the proposal, as modified by Amendment No. 1, is designed to remove impediments to, and perfect the mechanism of, a free and open market and a national market system, and to protect investors and the public interest.
Accordingly, for the reasons discussed above, the Commission believes that the Exchange's proposal, as modified by Amendment No. 1, is consistent with the Act.
It is therefore ordered, pursuant to Section 19(b)(2) of the Act,
that the proposed rule change (SR-NYSE-2018-31), as modified by Amendment No.1, be, and hereby is, approved.
For the Commission, by the Division of Trading and Markets, pursuant to delegated authority.18
