PTRSX Investment Objective and Strategy

PIMCO Total Return ESG Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by PIMCO Funds.

Investment objective

The Fund seeks maximum total return, consistent with preservation of capital and prudent investment management.

Principal investment strategy

"The Fund seeks to achieve its investment objective by investing under normal circumstances at least 65% of its total assets in a diversified portfolio of Fixed Income Instruments of varying maturities, which may be represented by forwards or derivatives such as options, futures contracts, or swap agreements. ""Fixed Income Instruments"" include bonds, debt securities and other similar instruments issued by various U.S. and non-U.S. public- or private-sector entities. The average portfolio duration of this Fund normally varies within two years (plus or minus) of the portfolio duration of the securities comprising the Bloomberg Barclays U.S. Aggregate Index, as calculated by PIMCO, which as of May 31, 2018 was 5.70 years. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates.

The longer a security's duration, the more sensitive it will be to changes in interest rates. The Fund will not invest in the securities of any issuer determined by PIMCO to be engaged principally in the manufacture of alcoholic beverages, tobacco products or military equipment, the operation of gambling casinos, the production of coal, or in the production or trade of pornographic materials. In addition, the Fund will not invest in the securities of any issuer determined by PIMCO to be engaged principally in the provision of healthcare services or the manufacture of pharmaceuticals, unless the issuer derives 100% of its gross revenues from products or services designed to protect and improve the quality of human life, as determined on the basis of information available to PIMCO. To the extent possible on the basis of information available to PIMCO, an issuer will be deemed to be principally engaged in an activity if it derives more than 10% of its gross revenues from such activities.

In addition, the Fund will not invest directly in securities of issuers that are engaged in certain business activities in or with the Republic of the Sudan. In analyzing whether an issuer meets any of the criteria described above, PIMCO may rely upon, among other things, information provided by an independent third party. The Fund may avoid investment in the securities of issuers whose business practices with respect to the environment, social responsibility, and governance (""ESG practices"") are not to PIMCO's satisfaction. In determining the efficacy of an issuer's ESG practices, PIMCO will use its own proprietary assessments of material ESG issues and may also reference standards as set forth by recognized global organizations such as entities sponsored by the United Nations. Additionally, PIMCO may engage proactively with issuers to encourage them to improve their ESG practices.

PIMCO's activities in this respect may include, but are not limited to, direct dialogue with company management, such as through in-person meetings, phone calls, electronic communications, and letters. Through these engagement activities, PIMCO seeks to identify opportunities for a company to improve its ESG practices, and will endeavor to work collaboratively with company management to establish concrete objectives and to develop a plan for meeting these objectives. The Fund may invest in securities of issuers whose ESG practices are currently suboptimal, with the expectation that these practices may improve over time either as a result of PIMCO's engagement efforts or through the company's own initiatives. It may also exclude those issuers that are not receptive to PIMCO's engagement efforts, as determined in PIMCO's sole discretion.

The Fund invests primarily in investment grade securities, but may invest up to 20% of its total assets in high yield securities (""junk bonds""), as rated by Moody's Investors Service, Inc. (""Moody's""), Standard & Poor's Ratings Services (""S&P"") or Fitch, Inc. (""Fitch""), or, if unrated, as determined by PIMCO. The Fund may invest up to 30% of its total assets in securities denominated in foreign currencies, and may invest beyond this limit in U.S. dollar-denominated securities of foreign issuers. The Fund may invest up to 15% of its total assets in securities and instruments that are economically tied to emerging market countries (this limitation does not apply to investment grade sovereign debt denominated in the local currency with less than 1 year remaining to maturity, which means the Fund may invest, together with any other investments denominated in foreign currencies, up to 30% of its total assets in such instruments).

The Fund will normally limit its foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to 20% of its total assets. The Fund may invest, without limitation, in derivative instruments, such as options, futures contracts or swap agreements, or in mortgage- or asset-backed securities, subject to applicable law and any other restrictions described in the Fund's prospectus or Statement of Additional Information. The Fund may purchase or sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales. The Fund may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls).

The ""total return"" sought by the Fund consists of income earned on the Fund's investments, plus capital appreciation, if any, which generally arises from decreases in interest rates, foreign currency appreciation, or improving credit fundamentals for a particular sector or security. The Fund may also invest up to 10% of its total assets in preferred securities."
