Fees and Expenses of the Fund

Shareholder Fees (fees paid directly from your investment):

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):

Example. The Example is intended to help you compare the cost of investing in Institutional Class, Class P, Administrative Class, Class D, Class A or Class C 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 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:

Expense Example - (PIMCO RAE Fundamental Advantage PLUS Fund) - USD ($)	1 Year	3 Years	5 Years	10 Years
Institutional Class	96	300	520	1,155
Class P	106	331	574	1,271
Administrative Class	121	378	654	1,443
Class D	136	425	734	1,613
Class A	506	784	1,082	1,927
Class C	312	655	1,124	2,421

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 602% of the average value of its portfolio.

The Fund seeks to achieve its investment objective under normal circumstances by obtaining long exposure to a portfolio of stocks ("RAE Fundamental 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 Fundamental US Large Model Portfolio stocks are selected by the Fund's sub-adviser, Research Affiliates, LLC ("Sub-Adviser"), from a broad universe of companies which satisfy certain liquidity and capacity requirements. Under normal circumstances equity total return swaps are used to obtain exposure to the RAE Fundamental US Large Model Portfolio and short positions in swaps and futures are used to obtain exposure to the S&P 500. The Fund's strategy of maintaining long exposure to the RAE Fundamental 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 Fundamental US Large Model Portfolio over the S&P 500.

The Sub-Adviser uses the RAFI® Fundamental Index® ("RAFI") methodology as a starting point for portfolio construction. The RAFI methodology is a non-capitalization method of creating and weighting an index of equity securities, within a defined market, that seeks to eliminate the potential overweighting of overpriced equity securities and underweighting of underpriced equity securities associated with market-capitalization equity indexes. Selections are further refined through the use of additional analytic measures and processes designed to achieve enhanced risk-adjusted returns including measures of financial health and adjustments that take momentum into account, among other factors. Actual stock positions in the RAE Fundamental US Large Model Portfolio, which drift apart from target weights as market prices change, are rebalanced to target weights periodically.

The Fund typically will seek to simultaneously gain long exposure to RAE Fundamental US Large Model Portfolio and short exposure to the S&P 500, each in an amount, under normal circumstances, approximately equal to the Fund's net assets. The Sub-Adviser provides investment advisory services in connection with the Fund's swap-based exposure to the RAE Fundamental US Large Model Portfolio by, among other things, providing Pacific Investment Management Company LLC ("PIMCO"), or counterparties designated by PIMCO, with the RAE Fundamental US Large Model Portfolio for purposes of developing equity total return swaps based on the RAE Fundamental US Large Model Portfolio. In a typical swap agreement, the Fund will receive the total return of the RAE Fundamental 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 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 Fundamental 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 Fundamental US Large Model Portfolio relative to the S&P 500. The Fund also may invest in exchange-traded funds.

The Fund seeks to maintain long exposure to the RAE Fundamental US Large Model Portfolio and short exposure to the S&P 500 even when the value of the RAE Fundamental US Large Model Portfolio is underperforming relative to the S&P 500.

In managing the Fund's investments in the AR Bond Alpha Strategy, Pacific Investment Management Company LLC ("PIMCO") seeks to outperform any residual net cost of obtaining long exposure to the RAE Fundamental 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, 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 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 forecast for interest rates 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 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 invest up to 20% of its total assets in high yield securities ("junk bonds") rated B or higher by Moody's Investors Service, Inc. ("Moody's"), or equivalently rated by Standard & Poor's Ratings Services ("S&P") or Fitch, Inc. ("Fitch"), or, if unrated, determined by PIMCO to be of comparable quality (except that within such 20% limitation, the Fund may invest in mortgage-related securities rated below B). 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 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 stocks.

It is possible to lose money on an investment in the Fund. In addition, under certain conditions, generally in a market where RAE Fundamental 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 will decline in value because of an increase 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

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 (e.g., 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 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 lose money if the issuer or guarantor of a fixed income security, or the counterparty to a derivative contract, is 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 credit, call and liquidity risks. High yield securities are considered primarily speculative with respect to the issuer's continuing ability to make principal and interest payments, and 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 go up or down, sometimes rapidly or unpredictably, due to factors affecting securities markets generally or particular industries

Issuer Risk: the risk that the value of a security may decline for a reason directly related to the issuer, such as management performance, financial leverage and 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 illiquid securities 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, and may be magnified in a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, causing increased supply in the market due to selling activity

Derivatives Risk: the risk of investing in derivative instruments (such as futures, swaps and structured securities), including liquidity, interest rate, market, credit and management risks, mispricing or valuation complexity. Changes in the value of the derivative 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. The Fund's use of derivatives may result in losses to the Fund, a reduction in the Fund's returns and/or increased volatility. Over-the-counter ("OTC") derivatives 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 OTC derivatives. For derivatives traded on an exchange or through a central counterparty, credit risk resides with the creditworthiness of the Fund's clearing broker, or the clearinghouse itself, rather than to a counterparty in an OTC derivative transaction. Changes in regulation relating to a mutual 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 and/or adversely affect the value or performance of derivatives and the Fund

Equity Risk: the risk that the value of equity securities, such as common stocks and preferred stocks, 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 securities generally have greater price volatility than fixed income securities

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

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 markets, differing reporting, accounting and auditing standards, increased risk of delayed settlement of portfolio transactions or loss of certificates of portfolio securities, and the risk of unfavorable foreign government actions, including nationalization, expropriation or confiscatory taxation, currency blockage, or political changes or diplomatic developments. 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 event 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 will decline in value relative to the U.S. dollar and affect 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, or 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

Management Risk: the risk that the investment techniques and risk analyses applied by PIMCO and Research Affiliates will not produce the desired results and that legislative, regulatory, or tax restrictions, policies or developments may affect the investment techniques available to PIMCO, Research Affiliates and the individual portfolio manager in connection with managing the Fund. There is no guarantee that the investment objective of the Fund will be achieved

Short Sale Risk: the risk of entering into short sales, 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 may fail to honor its contract terms, causing a loss to the Fund

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.

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 a broad-based securities market index and an index of similar funds. 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. For periods prior to the inception date of Class P shares (June 30, 2010) and Class D, Class A and Class C shares (July 31, 2008), performance information shown in the table for these classes is based on the performance of the Fund's Institutional Class shares, adjusted to reflect the actual distribution and/or service (12b-1) fees and other expenses paid by these classes of shares. Performance in the Average Annual Total Returns table reflects the impact of sales charges. The Administrative Class of the Fund has not commenced operations as of the date of this prospectus. The Fund's past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.

The 3 Month USD LIBOR (London Interbank Offered Rate) Index is an average interest rate, determined by the ICE Benchmark Administration, that banks charge one another for the use of short-term money (3 months) in England's Eurodollar market. The Lipper Alternative Equity Market Neutral Funds Average is a total return performance average of funds tracked by Lipper, Inc. that employ portfolio strategies generating consistent returns in both up and down markets by selecting positions with a total net market exposure of zero.

After-tax returns are calculated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Institutional Class shares only. After-tax returns for other classes will vary.

Fees and Expenses of the Fund

Shareholder Fees (fees paid directly from your investment):

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):

Example. The Example is intended to help you compare the cost of investing in Institutional Class, Class P, Administrative Class, Class D, Class A or Class C 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 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:

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 501% of the average value of its portfolio.

The Fund seeks to exceed the total return of the S&P 500 Index (the "S&P 500") under normal circumstances by obtaining exposure to a portfolio of stocks of U.S. companies ("RAE Fundamental US Large Model Portfolio"), and complementing this equity exposure with absolute return bond alpha strategy ("AR Bond Alpha Strategy"). The stocks are selected by the Fund's sub-adviser, Research Affiliates, LLC ("Sub-Adviser"), from a broad universe of companies which satisfy certain liquidity and capacity requirements.

The RAFI methodology is a non-capitalization method of creating and weighting an index of equity securities, within a defined market, that seeks to eliminate the potential overweighting of overpriced equity securities and underweighting of underpriced equity securities associated with market-capitalization equity indexes. The Sub-Adviser applies the RAFI methodology to the 1,000 largest U.S. companies by fundamental size. Selections are further refined through the use of additional analytic measures and processes designed to achieve enhanced risk-adjusted returns including measures of financial health and adjustments that take momentum into account, among other factors. Actual stock positions in the RAE Fundamental US Large Model Portfolio, which drift apart from target weights as market prices change, are rebalanced to target weights periodically.

The Sub-Adviser provides investment advisory services in connection with the Fund's swap-based exposure to the RAE Fundamental US Large Model Portfolio by, among other things, providing Pacific Investment Management Company LLC ("PIMCO"), or counterparties designated by PIMCO, with the RAE Fundamental US Large Model Portfolio for purposes of developing equity total return swaps based on the RAE Fundamental US Large Model Portfolio.

The Fund may also invest up to 10% of its total assets in preferred stocks.

The S&P 500 is an unmanaged index composed of 500 selected common stocks that represent approximately two-thirds of the total market value of all U.S. common stocks. The Fund may invest in common stocks, options, futures, options on futures and swaps.

It is possible to lose money on an investment in the Fund. Under certain conditions, generally in a market where the value of the RAE Fundamental US Large Model Portfolio underperforms the benchmark and/or 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 in the benchmark.
