Self-Regulatory Organizations; NASDAQ PHLX LLC; Notice of Designation of Longer Period for Commission Action on Proposed Rule Change To Permit the Listing and Trading of P.M.-Settled NASDAQ-100 Index® Options on a Pilot Basis

On January 18, 2017, NASDAQ PHLX LLC (“Phlx” or “Exchange”) 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 permit the listing and trading of P.M.-settled NASDAQ-100 Index® options on a pilot basis. The proposed rule change was published for comment in the Federal Register on February 3, 2017. The Commission has received no comment letters on the proposal.

Section 19(b)(2) of the Act provides that within 45 days of the publication of notice of the filing of a proposed rule change, or within such longer period up to 90 days as the Commission may designate if it finds such longer period to be appropriate and publishes its reasons for so finding or as to which the self-regulatory organization consents, the Commission shall either approve the proposed rule change, disapprove the proposed rule change, or institute proceedings to determine whether the proposed rule change should be disapproved. The 45th day for this filing is March 20, 2017.

The Commission is extending the 45-day time period for Commission action on the proposed rule change. The Commission finds that it is appropriate to designate a longer period within which to take action on the proposed rule change so that it has sufficient time to consider and take action on the Exchange's proposed rule change.

Accordingly, pursuant to Section 19(b)(2) of the Act and for the reasons stated above, the Commission designates May 4, 2017, as the date by which the Commission should either approve or disapprove, or institute proceedings to determine whether to disapprove, the proposed rule change (File No. SR-Phlx-2017-04).
