Strategy Narrative [Text Block]	The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its assets in a combination of (1) investments, either (i) the issuers of which have adopted ESG practices that compare favorably to other industries and/or issuers, or (ii) that are unlabeled and labeled green, sustainability, social and/or sustainability-linked instruments; and (2) Fixed Income Instrument investments, which may be represented by forwards or derivatives such as options, futures contracts, or swap agreements.“ESG practices” refers to business practices with respect to the environment, social responsibility and/or governance. “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 will vary based on PIMCO’s market forecasts and will normally not exceed one year. 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 dollar-weighted average portfolio maturity of the Fund is normally not expected to exceed three years. The Fund may avoid investment in the securities of issuers whose ESG practices do not meet criteria determined by PIMCO. 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, among others, and augment its assessments based on engagements with issuers regarding their ESG practices that have the potential to enhance risk-adjusted returns. 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. 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 PIMCO’s engagement efforts, as determined in PIMCO’s sole discretion. The Fund will not invest in the securities of any corporate 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) production or distribution of adult entertainment materials, (4) oil industry, including extraction, production, and refining or (5) production or distribution of coal and coal fired generation. 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, natural gas generation and sales and trading activities. The Fund may also invest in ESG labeled bonds, including but not limited to green, sustainability, social, transition 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 the bond will or has been used to fund projects that include eligible benefits or, in the case of a sustainability-linked bond, that the bond includes sustainability-linked covenants. 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 (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 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 primarily invests in U.S. dollar-denominated investment grade debt securities, rated Baa or higher by Moody’s Ratings (“Moody’s”), or equivalently rated by S&P Global Ratings (“S&P”) or Fitch Ratings, Inc. (“Fitch”), or, if unrated, determined by PIMCO to be of comparable quality. 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, without limitation, in U.S. dollar-denominated securities and instruments of foreign issuers. The Fund may invest up to 10% of its total assets in securities denominated in foreign currencies. The Fund seeks to eliminate foreign (non-U.S.) currency exposure (from non-U.S. dollar-denominated securities or currencies) through hedging techniques, although the Fund may have limited amounts of foreign (non-U.S.) currency exposure due to the difficulty in perfectly hedging such exposures. The Fund may invest, without limitation, in futures contracts, subject to applicable law and any other restrictions described in the Fund's prospectus or Statement of Additional Information. The Fund may invest in mortgage or asset-backed securities (issuers of which will not be treated as subject to the corporate issuer screens described herein), including to-be-announced transactions which may include exposure to issuers that the Fund is not permitted to invest in directly. The Fund may purchase and sell securities on a when-issued, delayed delivery or forward commitment basis. 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 Fund generally intends to consider the federal income tax impact of the manner in which it seeks to obtain and dispose of investment exposures.
