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 U.S. Aggregate Index, as calculated by PIMCO, which as of May 31, 2024 was 5.98 years.

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 U.S. Aggregate Index, as calculated by PIMCO, which as of May 31, 2024 was 5.98 years. Duration is a measure used to determine the sensitivity of a securitys price to changes in interest rates. The longer a securitys duration, the more sensitive it will be to changes in interest rates. The Fund will not invest in the securities of any non-governmental issuer determined by PIMCO to be engaged principally in the (1) manufacture of alcoholic beverages, tobacco products or military equipment, (2) operation of gambling casinos, (3) oil industry, including extraction, production, and refining, or (4) production or distribution of coal and coal fired generation. To the extent possible on the basis of information available to PIMCO, an issuer will be deemed to be engaged principally in an activity if it derives more than 10% of its gross revenues from such activities (or such more restrictive threshold or exclusionary screen (i.e., a lower gross revenue threshold), as may be determined by PIMCO from time to time). In addition, the Fund will not invest in the securities of any non-governmental issuer known to (1) derive gross revenue from the production, direction or publication of adult entertainment materials, as well as those known to be directly engaged in the business of distributing and retailing such materials, (2) provide abortions or manufacture abortifacients (and entities that own or are owned thereby), (3) manufacture products intended for contraception, (4) engage in certain types of stem cell research (including the use of embryonic or fetal stem cells to develop products), or (5) produce and/or retail cannabis for recreational use, each of the foregoing generally as determined by a third-party data provider and reported to PIMCO. In analyzing whether an issuer meets any of the criteria described in the foregoing sentence, PIMCO intends to predominantly rely upon, among other things, information provided by an independent third party, including research and screens employed for certain values-based or Catholic institutions such as the MSCI Catholic Values Screening Methodology and related research. Please see the Additional Information Regarding Certain Screens Used by the Fund section of the prospectus for additional information, including a description of the methodologies that may be used to determine whether a non-governmental issuer is known to be engaged in an activity. Notwithstanding the restrictions set forth above, the Fund can invest in the securities of any issuer determined by PIMCO to be engaged principally in biofuel production or natural gas generation or sales and trading activities. The Fund may also invest in labeled green, sustainability, social and sustainability-linked bonds from issuers involved in fossil fuel-related sectors. Labeled bonds are those issues with proceeds specifically earmarked to be used for climate (often referred to as green bonds), environmental sustainability and/or social projects and, in the case of sustainability-linked bonds, bonds that include sustainability-linked covenants, as explained by the issuer through use of a framework and/or legal documentation. Labeled bonds are often verified by a third party, which certifies that a bond will or has been used to fund projects that include eligible benefits or, in the case of sustainability-linked bonds, that the bond includes sustainability-linked covenants. The Fund may avoid investment in the securities of issuers whose business practices with respect to the environment, social responsibility, and governance (ESG practices) do not meet criteria determined by PIMCO. In determining the efficacy of an issuers 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, and augment its assessments based on engagements with issuers regarding their ESG practices that have the potential to enhance risk-adjusted returns. PIMCOs 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. The Fund may invest in securities of issuers whose ESG practices are weaker relative to certain peers or industry benchmarks, with the expectation that these practices may improve over time. It may also exclude those issuers that are not receptive to PIMCOs engagement efforts, as determined in PIMCOs 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 Moodys Investors Service, Inc. (Moodys), Standard & Poors Ratings Services (S&P) or Fitch Ratings, Inc. (Fitch), or, if unrated, as determined by PIMCO (except such 20% limitation shall not apply to the Fund's investments in mortgage- and asset-backed securities). In the event that ratings services assign different ratings to the same security, PIMCO will use the highest rating as the credit rating for that security. 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 (issuers of which generally will not be treated as subject to the non-governmental issuer screens described herein), subject to applicable law and any other restrictions described in the Funds prospectus or Statement of Additional Information. The Fund may invest in derivatives, such as credit default swaps, on indexes of securities which may include exposure to issuers that the Fund is not permitted to invest in directly. 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 Funds 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. Show less
