Example. The Example is intended to help you compare the cost of investing in Institutional Class or Class A shares of the Fund with the costs of investing in other mutual funds. The Example assumes that you

invest $10,000 in the noted class of shares for the time periods indicated, and then hold or redeem all your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

If you redeem your shares at the end of each period: 

	1 Year	3 Years	5 Years	10 Years
Institutional Class	$112	$350	$606	$1,340
Class A	$522	$831	$1,163	$2,098

If you do not redeem your shares: 

	1 Year	3 Years	5 Years	10 Years
Class A	$522	$831	$1,163	$2,098

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example tables, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 867% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by obtaining long exposure to a portfolio of stocks ("RAE US Large Model Portfolio") and short exposure to the S&P 500 Index ("S&P 500"), and complementing this equity market neutral exposure with absolute return bond alpha strategy ("AR Bond Alpha Strategy"). The RAE US Large Model Portfolio stocks are selected by the Fund's sub-adviser, Research Affiliates ("Sub-Adviser"), from a broad universe of companies which satisfy certain liquidity and capacity requirements. The Fund expects to use derivatives including equity total return swaps, with respect to the RAE US Large Model Portfolio, and short positions in swaps and futures with respect to the S&P 500, in addition to or in place of investments in stocks and/or equity-related underlying funds (such as exchange-traded funds) to obtain exposure to the RAE US Large Model Portfolio and the S&P 500. The Fund may seek equity exposure through any of the foregoing instruments, without limitation, in PIMCO's and the Sub-Adviser's discretion, as applicable. The Fund's strategy of maintaining long exposure to the RAE US Large Model Portfolio and short exposure to the S&P 500 can be characterized as "market neutral" because the long and the short exposures are intended to offset one another producing a net equity exposure that is approximately zero. At the same time, the Fund is designed to deliver the relative appreciation (or depreciation) of the RAE US Large Model Portfolio over the S&P 500.

In selecting investments for the Fund, PIMCO and the Sub-Adviser, as applicable, may use proprietary quantitative models that are developed and maintained by PIMCO or the Sub-Adviser, as applicable, and which are subject to change over time without notice in PIMCO's or the

Sub-Adviser's discretion, as applicable. The Sub-Adviser uses the RAE® methodology for portfolio construction. The RAE® methodology is a rules-based model that selects stocks using quantitative signals that indicate higher expected returns, e.g., value, quality, and momentum. The model then uses the expected return along with measures of liquidity, turnover, transaction cost and fundamental measures of company size, e.g., sales, cash flow, dividends and book value, to inform the weights of securities. Actual stock positions in the RAE US Large Model Portfolio, which drift apart from target weights as market prices change, are rebalanced to target weights periodically. The RAE methodology's systematic portfolio rebalancing reflects a value orientation. Portfolio managers do not have discretion with respect to the allocation determined by the RAE® methodology. The RAE® methodology is not updated according to any predetermined schedule.

The Fund typically will seek to simultaneously gain long exposure to RAE US Large Model Portfolio and short exposure to the S&P 500, each in an amount approximately equal to the Fund's net assets. The Sub-Adviser provides investment advisory services in connection with the Fund's exposure to the RAE US Large Model Portfolio by, among other things, providing PIMCO, or counterparties designated by PIMCO, with the RAE US Large Model Portfolio for purposes of developing equity total return swaps based on the RAE US Large Model Portfolio. In a typical swap agreement, the Fund will receive the total return of the RAE US Large Model Portfolio from the counterparty to the swap agreement in exchange for paying the counterparty an agreed upon short term interest rate. The Fund will typically invest in, among other instruments, short S&P 500 futures and/or total return swaps that provide the inverse of the total return of the S&P 500 index plus a short term interest rate.

Because the RAE US Large Model Portfolio is a proprietary portfolio, there may be a limited number of counterparties willing or able to serve as counterparties to a swap agreement. If such swap agreements are not available, or if swap pricing is unattractive or for other reasons, the Fund may invest in other instruments, "baskets" of stocks, or individual securities to replicate the performance of the RAE US Large Model Portfolio relative to the S&P 500.

The Fund seeks to maintain long exposure to the RAE US Large Model Portfolio and short exposure to the S&P 500 even when the value of the RAE US Large Model Portfolio is underperforming relative to the S&P 500. The S&P 500 Index is a group of 500 selected common stocks that represent approximately two-thirds of the total market value of all U.S. common stocks. The Fund uses the S&P 500 Index as a benchmark to measure performance, and seeks to remain invested in S&P 500 Index derivatives, S&P 500 Index stocks and/or equity-related underlying funds even when the S&P 500 Index is declining. The Fund is not based on and does not use any products or services from S&P Dow Jones Indices LLC ("SPDJI"), and is not affiliated or associated with, or sponsored, promoted or endorsed by, SPDJI, Standard & Poor's Financial Services LLC, S&P Global or any of their parent, subsidiary, or affiliated companies.

In managing the Fund's investments in the AR Bond Alpha Strategy, PIMCO seeks to outperform any residual net cost of obtaining long exposure to the RAE US Large Model Portfolio and short exposure to the S&P 500, thereby enhancing the Fund's total return and return versus the benchmark (sometimes referred to as "alpha"). The AR Bond Alpha Strategy invests in a diversified portfolio of Fixed Income Instruments and related derivatives, which may include 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 AR Bond Alpha Strategy is not designed to systematically provide bond market exposure, although the returns may (or may not) be positively correlated with the returns of the bond market.

The AR Bond Alpha Strategy seeks to maintain an overall portfolio duration which normally varies from (negative) 3 years to positive 8 years based on PIMCO's market forecasts among other factors.

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. In addition to duration, the AR Bond Alpha Strategy has flexibility with respect to overall sector exposures, non-U.S. exposures and credit quality, both as a function of the strategy's investment guidelines and lack of a bond market index benchmark.

The Fund may invest, without limitation, in common stocks (including any equity-related underlying funds) and 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 also engage in financing transactions, such as reverse repurchase agreements and/or total return swaps. The Fund may invest up to 20% of its total assets in high yield securities ("junk bonds"), as rated by Moody's Ratings ("Moody's"), Standard & Poor's Ratings Services ("S&P") or Fitch Ratings, Inc. ("Fitch"), or, if unrated, as determined by PIMCO. 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, without limitation, in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. With respect to the AR Bond Alpha Strategy, the Fund may invest up to 25% 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 in such instruments without limitation subject to any applicable legal or regulatory limitation). The Fund will normally limit its net foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to 35% of its total assets. The Fund will normally limit its exposure (from non-U.S. dollar-denominated securities or currencies) to each non-U.S. currency to 10% of its total assets. The Fund will normally limit its aggregate U.S. dollar exposure from

transactions or instruments that reference the relative return of a non-U.S. currency or currencies as compared to the U.S. dollar to 20% of its total assets. The Fund may also invest up to 10% of its total assets in preferred securities.

Principal Risks

It is possible to experience losses on an investment in the Fund. In addition, under certain conditions, generally in a market where RAE US Large Model Portfolio underperforms relative to the S&P 500 and/or where the AR Bond Alpha Strategy underperforms short-term interest rates, the Fund may experience greater losses or lesser gains than would be the case if it invested directly in securities designed to replicate the benchmark. The principal risks of investing in the Fund, which could adversely affect its net asset value, yield and total return, are:

Interest Rate Risk: the risk that fixed income securities and dividend-paying equity securities will fluctuate in value due to changes or the anticipation of changes in interest rates; a fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration. Factors such as government and central bank policy, inflation, the economy, and the market for bonds can impact interest rates and yields

Call Risk: the risk that an issuer may exercise its right to redeem a fixed income security earlier than expected (a call). Issuers may call outstanding securities prior to their maturity for a number of reasons including declining interest rates, changes in credit spreads and improvements in the issuer's credit quality. If an issuer calls a security that the Fund has invested in, the Fund may not recoup the full amount of its initial investment or may not realize the full anticipated earnings from the investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable features

Credit Risk: the risk that the Fund could experience losses if the issuer or guarantor of a fixed income security, the counterparty to a derivative contract or a repurchase agreement, a borrower of portfolio securities or the issuer or guarantor of collateral, is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services or otherwise) as unable or unwilling, to meet its financial obligations

High Yield Risk: the risk that high yield securities and unrated securities of similar credit quality (commonly known as "junk bonds") are subject to greater levels of market, credit, call and liquidity risks. High yield securities are considered primarily speculative by rating agencies with respect to the issuer's continuing ability to make principal and interest payments, and their values may be more volatile than higher-rated securities of similar maturity

Market Risk: the risk that the value of securities owned by the Fund may fluctuate, sometimes rapidly or unpredictably, due to a variety of factors affecting securities markets generally or particular industries or sectors

Issuer Risk: the risk that the value of a security may decline for reasons related to the issuer, such as management performance, changes in financial condition or credit rating, financial leverage, reputation or reduced demand for the issuer's goods or services

Liquidity Risk: the risk that a particular investment may be difficult to purchase or sell and that the Fund may be unable to sell investments at an advantageous time or price or achieve its desired level of exposure to a certain sector. Liquidity risk may result from the lack of an active market, reduced number and capacity of traditional market participants to make a market in fixed income securities, credit tightening and may be magnified in changing interest rate environments or other circumstances where investor redemptions from fixed income funds may be higher than normal, causing increased supply in the market due to selling activity. The liquidity of the Fund's shares may be constrained by the liquidity of the Fund's portfolio holdings

Derivatives Risk: the risk of investing in derivative instruments (such as forwards, futures, options, swaps and structured securities) and other similar investments, including leverage, liquidity, interest rate, market, counterparty (including credit), operational, legal and management risks, and valuation complexity. Changes in the value of a derivative or other similar investment may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and the Fund could lose more than the initial amount invested. Derivatives used for hedging or risk management may not operate as intended or may expose the Fund to additional risks. Changes in the value of a derivative or other similar instrument may also create margin delivery or settlement payment obligations for the Fund. The Fund's use of derivatives or other similar investments may result in losses to the Fund, a reduction in the Fund's returns and/or increased volatility. Non-centrally-cleared over-the-counter ("OTC") derivatives or other similar investments are also subject to the risk that a counterparty to the transaction will not fulfill its contractual obligations to the other party, as many of the protections afforded to centrally-cleared derivative transactions might not be available for non-centrally-cleared OTC derivatives or other similar investments. The primary credit risk on derivatives or other similar investments that are exchange-traded or traded through a central clearing counterparty resides with the Fund's clearing broker or the clearinghouse. Changes in regulations relating to a registered fund's use of derivatives and related instruments could potentially limit or impact the Fund's ability to invest in derivatives, limit the Fund's ability to employ certain strategies that use derivatives or other similar investments and/or adversely affect the value of derivatives or other similar investments and the Fund's performance

Equity Risk: the risk that the value of equity or equity-related securities, such as common stocks and preferred securities, may decline due to general market conditions which are not specifically related to a particular company or to factors affecting a particular industry or industries. Equity or equity-related securities generally have greater price volatility than fixed income securities. In addition, preferred securities may be subject to greater credit risk or other risks, such as

risks related to deferred and omitted distributions, limited voting rights, liquidity, interest rates, regulatory changes and special redemption rights

Mortgage-Related and Other Asset-Backed Securities Risk: the risks of investing in mortgage-related and other asset-backed securities, including interest rate risk, extension risk, prepayment risk and credit risk. The Fund may invest in any tranche of mortgage-related and other asset-backed securities, including junior and/or equity tranches (to the extent consistent with the Fund's guidelines), which generally carry higher levels of the foregoing risks

Foreign (Non-U.S.) Investment Risk: the risk that investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller or less developed markets, differing financial reporting, accounting, corporate governance and auditing standards, increased risk of delayed settlement of portfolio transactions or loss of certificates of portfolio securities, and the risk of unfavorable U.S. or foreign government actions, including nationalization, expropriation or confiscatory taxation, currency blockage, political changes, diplomatic developments, trade restrictions (including tariffs) or the imposition of sanctions and other similar measures. Foreign securities may also be less liquid and more difficult to value than securities of U.S. issuers

Emerging Markets Risk: the risk of investing in emerging market securities, primarily increased foreign (non-U.S.) investment risk

Sovereign Debt Risk: the risk that investments in fixed income instruments issued by sovereign entities may decline in value as a result of default or other adverse credit events resulting from an issuer's inability or unwillingness to make principal or interest payments in a timely fashion

Currency Risk: the risk that foreign (non-U.S.) currencies may fluctuate in value relative to the U.S. dollar, which can affect the value of the Fund's investments in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, or in derivatives that provide exposure to, foreign (non-U.S.) currencies

Leveraging Risk: the risk that certain transactions of the Fund, such as reverse repurchase agreements, loans of portfolio securities, and the use of when-issued, delayed delivery or forward commitment transactions, and derivative instruments, may give rise to leverage, magnifying gains and losses and causing the Fund to be more volatile than if it had not been leveraged. This means that leverage entails a heightened risk of loss. The use of leverage may also increase the Fund's sensitivity to interest rate changes and other market risks

Management Risk: the risk that the investment techniques and risk analyses applied by PIMCO and Research Affiliates, including the use of quantitative models or methods, will not produce the desired results and that actual or potential conflicts of interest, legislative, regulatory or tax restrictions, policies or developments may affect the investment techniques available to PIMCO or Research Affiliates in connection with managing the Fund and may cause PIMCO or Research Affiliates to

restrict or prohibit participation in certain investments. There is no guarantee that the investment objective of the Fund will be achieved

Model Risk: the risk that the Fund's investment models used in making investment allocation decisions may not adequately take into account certain factors, or may contain design flaws or faulty assumptions, and may rely on incomplete or inaccurate data inputs, any of which may result in a decline in the value of an investment in the Fund. The performance of the investment models may be impacted by software or other technology malfunctions, human error, issues related to the potential use of artificial intelligence and machine learning (AI), programming inaccuracies, power loss, and other events or circumstances, which may be difficult to detect and may be beyond the control of the Fund

Short Exposure Risk: the risk of entering into short sales or other short positions, including the potential loss of more money than the actual cost of the investment, and the risk that the third party to the short sale or other short position will not fulfill its contractual obligations, causing a loss to the Fund

Value Investing Risk: the risk that value stocks may decrease in price or may not increase in price as anticipated by the Sub-Adviser if they continue to be undervalued by the market or the factors that PIMCO believes will cause the stock price to increase do not occur

Collateralized Loan Obligations Risk:  the risk that investing in collateralized loan obligations ("CLOs") and other similarly structured investments exposes the Fund to heightened credit risk, interest rate risk, liquidity risk, market risk and prepayment and extension risk, as well as the risk of default on the underlying asset. In addition, investments in CLOs carry additional risks, including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) risks related to the capability of the servicer of the securitized assets; (iv) the risk that the Fund may invest in tranches of CLOs that are subordinate to other tranches; (v) the structure and complexity of the transaction and the legal documents may not be fully understood at the time of investment and could lead to disputes with the issuer or among investors regarding the characterization of proceeds or unexpected investment results; and (vi) the CLO's manager may perform poorly

Acquired Fund Risk: the risk that the Fund's performance is closely related to the risks associated with the securities and other investments held by the Acquired Funds and that the ability of the Fund to achieve its investment objective will depend upon the ability of the Acquired Funds to achieve their investment objectives. Investments in Acquired Funds that are exchange-traded funds are also subject to market risk, tracking error, the potential for trading at a discount or premium to their net asset value, bid/ask spread risk as well as the risks of the underlying securities they hold. In addition, the Fund's performance will be reduced by the Fund's proportionate amount of the expenses of any Acquired Funds in which it invests

Turnover Risk:  the risk that high levels of portfolio turnover may increase transaction costs and taxes and may lower investment performance

Please see "Description of Principal Risks" in the Fund's prospectus for a more detailed description of the risks of investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information shows summary performance information for the Fund in a bar chart and an Average Annual Total Returns table. The information provides some indication of the risks of investing in the Fund by showing changes in its performance from year to year and by showing how the Fund's average annual returns compare with the returns of certain indexes. Absent any applicable fee waivers and/or expense limitations, performance would have been lower. The bar chart shows performance of the Fund's Institutional Class shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. The Fund's past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.

In addition to the Fund's performance, the Average Annual Total Returns table includes performance of: (i) a broad-based securities market index (i.e., a regulatory index) and (ii) a supplemental index. It is not possible to invest directly in an unmanaged index. The Fund's regulatory index is the S&P 500 Index. The Fund's regulatory index is shown in connection with certain regulatory requirements to provide a broad measure of market performance. The S&P 500 Index is an unmanaged market index generally considered representative of the stock market as a whole. The S&P 500 Index is comprised of 500 selected common stocks that represent approximately two thirds of the total market value of all U.S. common stocks. The S&P 500 Index focuses on the large-cap segment of the U.S. equities market. The supplemental index shown is the ICE BofA SOFR Overnight Rate Index. The ICE BofA SOFR Overnight Rate Index tracks the performance of a synthetic asset paying SOFR to a stated maturity. The index is based on the assumed purchase at par of a synthetic instrument having exactly its stated maturity and with a coupon equal to that day's fixing rate. That issue is assumed to be sold the following business day (priced at a yield equal to the current day fixing rate) and rolled into a new instrument. SOFR (Secured Overnight Funding Rate) is an overnight rate (published in arrears) and was chosen by the Alternative Reference Rates Committee ("ARRC") as the successor to the USD LIBOR (London Interbank Offered Rate). SOFR is secured (collateralized by Treasuries), calculated by the Federal Reserve Bank of New York, and transactions based.
