          - [Release No. 34-64282; File No. SR-Phlx-2011-28]

## I. Introduction

                    On March 2, 2011, NASDAQ OMX PHLX LLC (the “Exchange” or “Phlx”) filed with the Securities and Exchange Commission (“Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”)[1]                                          and Rule 19b-4 thereunder,[2]                                          a proposed rule change to expand the number of components in the PHLX Oil Service Sector[SM]                      (the “Index” or “OSX”[SM]                     ) and to change the Index weighting methodology. The proposed rule change was published for comment in the                     **Federal Register**                     on March 17, 2011.[3]                                          The Commission received no comments on the proposal.                

                    Section 19(b)(2) of the Act [4]                                          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 May 1, 2011.                

The Commission is hereby extending the 45-day 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 the proposed rule change, which relates to the addition of components to the Index and a change to the Index weighting methodology.

                    Accordingly, pursuant to Section 19(b)(2)(A)(ii)(I) of the Act [5]                                          and for the reason stated above, the Commission designates June 15, 2011, 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-2011-28.                                    

                        For the Commission, by the Division of Trading and Markets, pursuant to delegated authority.6

Cathy H. Ahn,

Deputy Secretary.
