(1)		If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.
(2)		Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity's credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.
(3)		The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.
(4)		The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument's credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.
(5)		Unsettled variation margin asset of $8 and liability of $(4) for closed swap agreements is outstanding at period end.

Cash of $14,670 has been pledged as collateral for exchange-traded and centrally cleared financial derivative instruments as of September 30, 2023.
(1)	If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.
(2)	Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity's credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.
(3)	The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.
(4)	The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument's credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.
(5)	This instrument has a forward starting effective date.

(1)		If the Fund is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) receive from the seller of protection an amount equal to the notional amount of the swap and deliver the referenced obligation or underlying securities comprising the referenced index or (ii) receive a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.
(2)		The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.
(3)		The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument's credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(1)		If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.
(2)		Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity's credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.
(3)		The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.
(4)		The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument's credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(h)	Securities with an aggregate market value of $925 and cash of $1,289 have been pledged as collateral for exchange-traded and centrally cleared financial derivative instruments as of September 30, 2023.
(1)	If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.
(2)	Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity's credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.
(3)	The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.
(4)	The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument's credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(1)		If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.
(2)		Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity's credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.
(3)		The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.
(4)		The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument's credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

Notes to Financial Statements

1. BASIS FOR CONSOLIDATION

The Commodity Subsidiary, a Cayman Islands exempted company, was incorporated on January 19, 2023, as a wholly owned subsidiary acting as an investment vehicle for the PIMCO Commodity Strategy Active Exchange-Traded Fund in order to effect certain investments for the Fund consistent with the Fund’s investment objectives and policies as specified in its prospectus and statement of additional information. The Fund’s investment portfolio has been consolidated and includes the portfolio holdings of the Fund and the Commodity Subsidiary. The consolidated financial statements include the accounts of the Fund and the Commodity Subsidiary, if any. All inter-company transactions and balances have been eliminated. A subscription agreement was entered into between the Fund and the Commodity Subsidiary, comprising the entire issued share capital of the Commodity Subsidiary, with the intent that the Fund will remain the sole shareholder and retain all rights. Under the Memorandum and Articles of Association, shares issued by the Commodity Subsidiary confer upon a shareholder the right to receive notice of, to attend and to vote at general meetings of the Commodity Subsidiary and shall confer upon the shareholder rights in a winding-up or repayment of capital and the right to participate in the profits or assets of the Commodity Subsidiary. The net assets of the Commodity Subsidiary as of period end represented 5.7% of the Fund’s consolidated net assets.

2. INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS

(a) Investment Valuation PoliciesThe net asset value (“NAV”) of a Fund’s shares, or each of their respective share classes as applicable, is determined by dividing the total value of portfolio investments and other assets attributable to the Fund or class, less any liabilities, as applicable, by the total number of shares outstanding.

On each day that the New York Stock Exchange (“NYSE”) is open, the Funds’ shares are ordinarily valued as of the close of regular trading (normally 4:00 p.m., Eastern time) (“NYSE Close”). Information that becomes known to the Funds or their agents after the time as of which NAV has been calculated on a particular day will not generally be used to retroactively adjust the price of a security or the NAV determined earlier that day. If regular trading on the NYSE closes earlier than scheduled, each Fund may calculate its NAV as of the earlier closing time or calculate its NAV as of the NYSE Close for that day. Each Fund generally does not calculate its NAV on days on which the NYSE is not open for business. If the NYSE is closed on a day it would normally be open for business, each Fund may calculate its NAV as of the NYSE Close for such day or such other time that a Fund may determine.

For purposes of calculating NAV, portfolio securities and other assets for which market quotations are readily available are valued at market value. A market quotation is readily available only when that quotation is a quoted price (unadjusted) in active markets for identical investments that a Fund can access at the measurement date, provided that a quotation will not be readily available if it is not reliable. Market value is generally determined on the basis of official closing prices or the last reported sales prices. The Funds will normally use pricing data for domestic equity securities received shortly after the NYSE Close and do not normally take into account trading, clearances or settlements that take place after the NYSE Close. A foreign (non-U.S.) equity security traded on a foreign exchange or on more than one exchange is typically valued using pricing information from the exchange considered by the Pacific Investment Management Company LLC (“PIMCO” or “Manager”) to be the primary exchange. If market value pricing is used, a foreign (non-U.S.) equity security will be valued as of the close of trading on the foreign exchange, or the NYSE Close, if the NYSE Close occurs before the end of trading on the foreign exchange.

Investments for which market quotations are not readily available are valued at fair value as determined in good faith pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended (the “Act”). As a general principle, the fair value of a security or other asset is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Pursuant to Rule 2a-5, the Board of Trustees has designated PIMCO as the valuation designee (“Valuation Designee”) for each Fund to perform the fair value determination relating to all Fund investments. PIMCO may carry out its designated responsibilities as Valuation Designee through various teams and committees. The Valuation Designee’s policies and procedures govern the Valuation Designee’s selection and application of methodologies for determining and calculating the fair value of Fund investments. The Valuation Designee may value Fund portfolio securities for which market quotations are not readily available and other Fund assets utilizing inputs from pricing services, quotation reporting systems, valuation agents and other third-party sources (together, “Pricing Sources”).

Domestic and foreign (non-U.S.) fixed income securities, non-exchange traded derivatives, and equity options are normally valued on the basis of quotes obtained from brokers and dealers or Pricing Sources using data reflecting the earlier closing of the principal markets for those securities. Prices obtained from Pricing Sources may be based on, among other things, information provided by market makers or estimates of market values obtained from yield data relating to investments or securities with similar characteristics. Certain fixed income securities purchased on a delayed-delivery basis are marked to market daily until settlement at the forward settlement date. Exchange traded options, except equity options, futures and options on futures are valued at the settlement price determined by the relevant exchange. Swap agreements are valued on the basis of bid quotes obtained from brokers and dealers or market-based prices supplied by Pricing Sources. With respect to any portion of a Fund’s assets that are invested in one or more open-end management investment companies (other than ETFs), a Fund’s NAV will be calculated based on the NAVs of such investments. Open-end management investment companies may include affiliated funds.

If a foreign (non-U.S.) equity security’s value has materially changed after the close of the security’s primary exchange or principal market but before the NYSE Close, the security may be valued at fair value. Foreign (non-U.S.) equity securities that do not trade when the NYSE is open are also valued at fair value. With respect to foreign (non-U.S.) equity securities, a Fund may determine the fair value of investments based on information provided by Pricing Sources, which may recommend fair value or adjustments with reference to other securities, indexes or assets. In considering whether fair valuation is required and in determining fair values, the Valuation Designee may, among other things, consider significant events (which may be considered to include changes in the value of U.S. securities or securities indexes) that occur after the close of the relevant market and before the NYSE Close. A Fund may utilize modeling tools provided by third-party vendors to determine fair values of foreign (non-U.S.) securities. For these purposes, unless otherwise determined by the Valuation Designee, any movement in the applicable reference index or instrument (“zero trigger”) between the earlier close of the applicable foreign market and the NYSE Close may be deemed to be a significant event, prompting the application of the pricing model (effectively resulting in daily fair valuations). Foreign exchanges may permit trading in foreign (non-U.S.) equity securities on days when a Fund is not open for business, which may result in a Fund's portfolio investments being affected when shareholders are unable to buy or sell shares.

Investments valued in currencies other than the U.S. dollar are converted to the U.S. dollar using exchange rates obtained from Pricing Sources. As a result, the value of such investments and, in turn, the NAV of a Fund's shares may be affected by changes in the value of currencies in relation to the U.S. dollar. The value of investments traded in markets outside the United States or denominated in currencies other than the U.S. dollar may be affected significantly on a day that the Trust is not open for business. As a result, to the extent that a Fund holds foreign (non-U.S.) investments, the value of those investments may change at times when shareholders are unable to buy or sell shares and the value of such investments will be reflected in a Fund's next calculated NAV.

Fair valuation may require subjective determinations about the value of a security. While the Trust’s and Valuation Designee’s policies and procedures are intended to result in a calculation of a Fund's NAV that fairly reflects security values as of the time of pricing, the Trust cannot ensure that fair values accurately reflect the price that a Fund could obtain for a security if it were to dispose of that security as of the time of pricing (for instance, in a forced or distressed sale). The prices used by a Fund may differ from the value that would be

realized if the securities were sold. The Funds' use of fair valuation may also help to deter “stale price arbitrage” as discussed under the "Abusive Trading Practices" section in each Fund's prospectus.

(b) Fair Value Hierarchy U.S. GAAP describes fair value as the price that a Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. It establishes a fair value hierarchy that prioritizes inputs to valuation methods and requires disclosure of the fair value hierarchy, separately for each major category of assets and liabilities, that segregates fair value measurements into levels (Level 1, 2, or 3). The inputs or methodology used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. Levels 1, 2, and 3 of the fair value hierarchy are defined as follows:

• Level 1 — Quoted prices (unadjusted) in active markets or exchanges for identical assets and liabilities.

• Level 2 — Significant other observable inputs, which may include, but are not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market corroborated inputs.

• Level 3 — Significant unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available, which may include assumptions made by the Valuation Designee that are used in determining the fair value of investments.

Assets or liabilities categorized as Level 2 or 3 as of period end have been transferred between Levels 2 and 3 since the prior period due to changes in the method utilized in valuing the investments. Transfers from Level 2 to Level 3 are a result of a change, in the normal course of business, from the use of methods used by Pricing Sources (Level 2) to the use of a Broker Quote or valuation technique which utilizes significant unobservable inputs due to an absence of current or reliable market-based data (Level 3). Transfers from Level 3 to Level 2 are a result of the availability of current and reliable market-based data provided by Pricing Sources or other valuation techniques which utilize significant observable inputs. In accordance with the requirements of U.S. GAAP, the amounts of transfers into and out of Level 3, if material, are disclosed in the Notes to Schedule of Investments for each respective Fund.

For fair valuations using significant unobservable inputs, U.S. GAAP requires a reconciliation of the beginning to ending balances for reported fair values that presents changes attributable to realized gain (loss), unrealized appreciation (depreciation), purchases and sales, accrued discounts (premiums), and transfers into and out of the Level 3 category during the period. The end of period value is used for the transfers between Levels of a Fund's assets and liabilities. Additionally, U.S. GAAP requires quantitative information regarding the significant unobservable inputs used in the determination of fair value of assets or liabilities categorized as Level 3 in the fair value hierarchy. In accordance with the requirements of U.S. GAAP, a fair value hierarchy, and if material, a Level 3 reconciliation and details of significant unobservable inputs, have been included in the Notes to Schedule of Investments for each respective Fund.

(c) Valuation Techniques and the Fair Value Hierarchy

Level 1, Level 2 and Level 3 trading assets and trading liabilities, at fair value The valuation methods (or “techniques”) and significant inputs used in determining the fair values of portfolio securities or other assets and liabilities categorized as Level 1, Level 2 and Level 3 of the fair value hierarchy are as follows:

Common stocks, ETFs, exchange-traded notes and financial derivative instruments, such as futures contracts, rights and warrants, or options on futures that are traded on a national securities exchange, are stated at the last reported sale or settlement price on the day of valuation. To the extent these securities are actively traded and valuation adjustments are not applied, they are categorized as Level 1 of the fair value hierarchy.

Investments in registered open-end investment companies (other than ETFs) will be valued based upon the NAVs of such investments and are categorized as Level 1 of the fair value hierarchy. Investments in unregistered open-end investment companies will be calculated based upon the NAVs of such investments and are considered Level 1 provided that the NAVs are observable, calculated daily and are the value at which both purchases and sales will be conducted.

Fixed income securities including corporate, convertible and municipal bonds and notes, U.S. government agencies, U.S. treasury obligations, sovereign issues, bank loans, convertible preferred securities, non-U.S. bonds, and short-term debt instruments (such as commercial paper, time deposits, and certificates of deposit) are normally valued on the basis of quotes obtained from brokers and dealers or Pricing Sources that use broker-dealer quotations, reported trades or valuation estimates from their internal pricing models. The Pricing Sources' internal models use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar assets. Securities that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Fixed income securities purchased on a delayed-delivery basis or as a repurchase commitment in a sale-buyback transaction are marked to market daily until settlement at the forward settlement date and are categorized as Level 2 of the fair value hierarchy.

Mortgage-related and asset-backed securities are usually issued as separate tranches, or classes, of securities within each deal. These securities are also normally valued by Pricing Sources that use broker-dealer quotations, reported trades or valuation estimates from their internal pricing models. The pricing models for these securities usually consider tranche-level attributes, current market data, estimated cash flows and market-based yield spreads for each tranche, and incorporate deal collateral performance, as available. Mortgage-related and asset-backed securities that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Valuation adjustments may be applied to certain securities that are solely traded on a foreign exchange to account for the market movement between the close of the foreign market and the NYSE Close. These securities are valued using Pricing Sources that consider the correlation of the trading patterns of the foreign security to the intraday trading in the U.S. markets for investments. Securities using these valuation adjustments are categorized as Level 2 of the fair value hierarchy. Preferred securities and other equities traded on inactive markets or valued by reference to similar instruments are also categorized as Level 2 of the fair value hierarchy.

Valuation adjustments may be applied to certain exchange traded futures and options to account for market movement between the exchange settlement and the NYSE close. These securities are valued using quotes obtained from a quotation reporting system, established market makers or Pricing Sources. Financial derivatives using these valuation adjustments are categorized as Level 2 of the fair value hierarchy.

Notes to Financial Statements (Cont.)

Equity exchange-traded options and over the counter financial derivative instruments, such as forward foreign currency contracts and options contracts derive their value from underlying asset prices, indexes, reference rates, and other inputs or a combination of these factors. These contracts are normally valued on the basis of quotes obtained from a quotation reporting system, established market makers or Pricing Sources (normally determined as of the NYSE Close). Depending on the product and the terms of the transaction, financial derivative instruments can be valued by Pricing Sources using a series of techniques, including simulation pricing models. The pricing models use inputs that are observed from actively quoted markets such as quoted prices, issuer details, indexes, bid/ask spreads, interest rates, implied volatilities, yield curves, dividends and exchange rates. Financial derivative instruments that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Centrally cleared swaps and over the counter swaps derive their value from underlying asset prices, indexes, reference rates, and other inputs or a combination of these factors. They are valued using a broker-dealer bid quotation or on market-based prices provided by Pricing Sources (normally determined as of the NYSE Close). Centrally cleared swaps and over the counter swaps can be valued by Pricing Sources using a series of techniques, including simulation pricing models. The pricing models may use inputs that are observed from actively quoted markets such as the overnight index swap rate, LIBOR forward rate, interest rates, yield curves and credit spreads. These securities are categorized as Level 2 of the fair value hierarchy.

Proxy pricing procedures set the base price of a fixed income security and subsequently adjust the price proportionally to market value changes of a pre-determined security deemed to be comparable in duration, generally a U.S. Treasury or sovereign note based on country of issuance. The base price may be a broker-dealer quote, transaction price or an internal value as derived by analysis of market data. The base price of the security may be reset on a periodic basis based on the availability of market data and procedures approved by the Valuation Oversight Committee. Significant changes in the unobservable inputs of the proxy pricing process (the base price) would result in direct and proportional changes in the fair value of the security. These securities are categorized as Level 3 of the fair value hierarchy.

If third-party evaluated vendor pricing is not available or not deemed to be indicative of fair value, the Manager may elect to obtain Broker Quotes directly from the broker-dealer or passed through from a third-party vendor. In the event that fair value is based upon a single sourced Broker Quote, these securities are categorized as Level 3 of the fair value hierarchy. Broker Quotes are typically received from established market participants. Although independently received, the Manager does not have the transparency to view the underlying inputs which support the market quotation. Significant changes in the Broker Quote would have direct and proportional changes in the fair value of the security.

The Discounted Cash Flow model is based on future cash flows generated by the investment and may be normalized based on expected investment performance. Future cash flows are discounted to present value using an appropriate rate of return, typically calibrated to the initial transaction date and adjusted based on Capital Asset Pricing Model and/or other market-based inputs. Significant changes in the unobservable inputs would result in direct and proportional changes in the fair value of the security. These securities are categorized as Level 3 of the fair value hierarchy.

Securities may be valued based on purchase prices of privately negotiated transactions. Significant changes in the unobservable inputs would result in direct and proportional changes in the fair value of the security. These securities are categorized as Level 3 of the fair value hierarchy.

Securities that are smaller in size than institutional-sized or round lot positions of the particular security/instrument type may apply an adjustment factor to the daily vendor-provided price for the corresponding round lot position to arrive at a fair value for the applicable odd lot positions. The adjustment factor is determined by comparing the prices of internal trades with vendor prices, calculating the weighted average differences, and using that difference as an adjustment factor to vendor prices. These securities are categorized as Level 3 of the fair value hierarchy.

Short-term debt instruments (such as commercial paper, time deposits, and certificates of deposit) having a remaining maturity of 60 days or less may be valued at amortized cost, so long as the amortized cost value of such short-term debt instruments is approximately the same as the fair value of the instrument as determined without the use of amortized cost valuation. These securities are categorized as Level 2 or Level 3 of the fair value hierarchy depending on the source of the base price.

When a fair valuation method is applied by PIMCO that uses significant unobservable inputs, investments will be priced by a method that the Valuation Designee believes reflects fair value and are categorized as Level 3 of the fair value hierarchy.

3. FEDERAL INCOME TAX MATTERS

Each Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code (the “Code”) and distribute all of its taxable income and net realized gains, if applicable, to shareholders. Accordingly, no provision for Federal income taxes has been made.

A Fund may be subject to local withholding taxes, including those imposed on realized capital gains. Any applicable foreign capital gains tax is accrued daily based upon net unrealized gains, and may be payable following the sale of any applicable investments.

In accordance with U.S. GAAP, the Manager has reviewed the Funds' tax positions for all open tax years. As of September 30, 2023, the Funds have recorded no liability for net unrecognized tax benefits relating to uncertain income tax positions they have taken or expect to take in future tax returns.

The Funds file U.S. federal, state, and local tax returns as required. The Funds' tax returns are subject to examination by relevant tax authorities until expiration of the applicable statute of limitations, which is generally three years after the filing of the tax return but which can be extended to six years in certain circumstances. Tax returns for open years have incorporated no uncertain tax positions that require a provision for income taxes.

4. INVESTMENTS IN AFFILIATES

Each Fund eligible to participate in securities lending may invest the cash collateral received for securities out on loan in the PIMCO Government Money Market Fund under the Securities Lending Agreement. PIMCO Government Money Market Fund is considered to be affiliated with the Funds. A copy of each affiliate fund’s shareholder report is available at the U.S. Securities and Exchange Commission (“SEC”) website at www.sec.gov, on the Funds’ website at www.pimco.com, or upon request, as applicable. The table below shows the Funds’ transactions in and earnings from investments in the affiliated Fund for the period ended September 30, 2023 (amounts in thousands†):
