July 16, 2015.
Pursuant to Section 19(b)(1) 
of the Securities Exchange Act of 1934 (the “Act”) 
and Rule 19b-4 thereunder,
notice is hereby given that, on July 10, 2015, NYSE Arca, Inc. (the “Exchange” or “NYSE Arca”) filed with the Securities and Exchange Commission (the “Commission”) the proposed rule change as described in Items I and II below, which Items have been prepared by the Exchange. The Commission is publishing this notice to solicit comments on the proposed rule change from interested persons.
I. Self-Regulatory Organization's Statement of the Terms of the Substance of the Proposed Rule Change
The Exchange proposes to reflect a change in the size of a Creation Unit applicable to shares of the PIMCO Total Return Active Exchange-Traded Fund from 100,000 Shares to at least 50,000 Shares. The Fund is currently listed and traded on the Exchange under NYSE Arca Equities Rule 8.600. The text of the proposed rule change is available on the Exchange's Web site at www.nyse.com, at the principal office of the Exchange, 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 self-regulatory organization 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 those 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 parts of such statements.
A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change
The Commission has approved a proposed rule change relating to listing and trading on the Exchange of shares (“Shares”) of the PIMCO Total Return Active Exchange-Traded Fund (“Fund”) under NYSE Arca Equities Rule 8.600,
which governs the listing and trading of Managed Fund Shares.
The Shares are offered by PIMCO ETF Trust (the “Trust”), a statutory trust organized under the laws of the State of Delaware and registered with the Commission as an open-end management investment company.
The investment manager to the Fund is Pacific Investment Management Company LLC (“PIMCO” or the “Adviser”). The Fund's Shares are currently listed and traded on the Exchange under NYSE Arca Equities Rule 8.600.
According to the Registration Statement and the Prior Release, Shares of the Fund that trade in the secondary market are created at net asset value (“NAV”) by Authorized Participants only in block-size Creation Units of 100,000 Shares or multiples thereof.
The Exchange proposes to reflect a change in the size of a Creation Unit from 100,000 Shares to at least 50,000 Shares.
The size of a Creation Unit will be subject to change. The Exchange believes that the change to the size of a Creation Unit will not adversely impact investors or Exchange trading. A reduction in the size of a Creation Unit may provide potential benefits to investors by facilitating additional creation and redemption activity in the Shares, thereby potentially resulting in increased secondary market trading activity, tighter bid/ask spreads and narrower premiums or discounts to NAV.

The Adviser represents that the proposed change to reduce the size of a Creation Unit, as described above, is consistent with the Fund's investment objective, and will further assist the Adviser to achieve such investment objective. Except for the change noted above, all other representations made in the Prior Release remain unchanged.
The Fund will continue to comply with all initial and continued listing requirements under NYSE Arca Equities Rule 8.600. The Adviser represents that the investment objective of the Fund is not changing.
2. Statutory Basis
The basis under the Act for this proposed rule change is the requirement under Section 6(b)(5) 
that an exchange have rules that are designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to remove impediments to, and perfect the mechanism of a free and open market and, in general, to protect investors and the public interest.
The proposed rule change is designed to perfect the mechanism of a free and open market and, in general, to protect investors and the public interest. The Exchange believes that the change to the size of a Creation Unit to at least 50,000 Shares will not adversely impact investors or Exchange trading. In addition, a reduction in the size of a Creation Unit may provide potential benefits to investors by facilitating additional creation and redemption activity in the Shares, thereby potentially resulting in increased secondary market trading activity, tighter bid/ask spreads and narrower premiums or discounts to NAV.
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 purpose of the Act. The Exchange believes the proposed rule change, because of the potential increase in secondary market trading activity that may result from a decrease in the Creation Unit size for Shares of the Fund, will enhance competition among issues of exchange-traded funds that invest in fixed income securities.
C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others
No written comments were solicited or received with respect to 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, if consistent with the protection of investors and the public interest, the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act 
and Rule 19b-4(f)(6) thereunder.
At any time within 60 days of the filing of the proposed rule change, the Commission 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.
