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 diversified portfolio of Senior Loans and short-term investments, which may be represented by forwards or derivatives such as options, futures contracts or swap agreements.“Senior Loans” include senior secured floating rate bank loans, also referred to as leveraged loans, bank loans and floating rate loans, that are first or second lien loans. “Short-term investments” as used above includes debt instruments with 3 or fewer years remaining to maturity or weighted average life of less than 3 years; futures and options with 3 or fewer years remaining to expiration; swaps on instruments with 3 or fewer years remaining to maturity; and holdings of PIMCO Short-Term Floating NAV Portfolio III and PIMCO Short Asset Portfolio. As used above, “short-term investments” does not include reverse repurchase agreements or securities held as collateral in securities lending arrangements. The Fund may also invest in collateralized loan obligations and high-yield corporate debt securities, which may also be represented by forwards or derivatives such as options, futures contracts or swap agreements. A Senior Loan holds a senior position in the issuer’s capital structure and is typically secured by collateral such that, under normal circumstances, holders (such as the Fund) enjoy a priority claim to some or all of the issuer’s assets in the event of default as compared to other creditors of the issuer. Floating rate bank loans generally pay interest at rates that adjust whenever a specified interest rate changes and/or reset on predetermined dates (such as the last day of a month or calendar quarter). The Fund may invest, without limitation, in high yield securities (“junk bonds”) rated below investment grade 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 also invest up to 20% of its total assets in securities denominated in foreign currencies. The Fund may invest without limit in U.S. dollar-denominated securities of foreign issuers. The Fund will normally limit its net foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to 20% of its total assets. The Fund may invest in derivative instruments, such as credit default swap and total return swap agreements, interest rate swaps, futures and options, subject to applicable law and any other restrictions described in the prospectus or Statement of Additional Information. The Fund may purchase or sell securities on a when-issued, delayed delivery or forward commitment basis, including currency forwards, and may engage in short sales. The Fund may invest up to 20% of its total assets in preferred stock. The average portfolio duration of the Fund will normally vary within one year (plus or minus) of the portfolio duration of the securities comprising the Markit iBoxx USD Liquid Leveraged Loan Index, as calculated by PIMCO, which as of September 30, 2026 was 0.12 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 generally intends to consider the federal income tax impact of the manner in which it seeks to obtain and dispose of investment exposures.
