"Other Expenses" reflect interest expense. Interest expense results from the Fund's use of certain investments such as reverse repurchase agreements. Such expense is required to be treated as a Fund expense for accounting purposes and is not payable to PIMCO. Any interest expense amount will vary based on the Fund's use of those investments as an investment strategy best suited to seek the objective of the Fund.

Total Annual Fund Operating Expenses excluding interest expense is 0.64%, 0.74%, 0.89% and 1.04% for Institutional Class, Class P, Administrative Class and Class D shares, respectively.

Example. The Example is intended to help you compare the cost of investing in Institutional Class, Class P, Administrative Class or Class D 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, the Example shows what your costs would be based on these assumptions.

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 635% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing primarily in short positions with respect to the S&P 500 Index (the "Index") or specific Index securities, backed by a portfolio of Fixed Income Instruments, such that the Fund's net asset value may vary inversely with the value of the Index on a daily basis, subject to certain limitations summarized below. In managing the Fund's investments in Fixed Income Instruments, PIMCO utilizes an absolute return approach, which is designed to have more discretion 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 fixed income index benchmark. The absolute return approach does not apply to the equity index replicating component of the Fund. "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 Fund will generally benefit when the price of the Index is declining. When the Index is rising, the Fund will generally not perform as well. Fixed Income Instruments owned by the Fund may also benefit or detract from the Fund's net asset value. The Fund is designed for investors seeking to take advantage of declines in the value of the Index, or investors wishing to hedge existing long equity positions. However, the Fund is not designed or expected to produce returns which replicate the inverse of the performance of the Index due to compounding, Pacific Investment Management Company LLC's ("PIMCO") active management, Fund fees and expenses and other factors discussed below.

The Fund will maintain short positions through the use of a combination of derivatives, including options, futures, options on futures, and swaps. The Fund may invest, without limitation, in such instruments. While the Fund will, under normal circumstances, invest primarily in Index short positions backed by a portfolio of Fixed Income Instruments, PIMCO may reduce the Fund's exposure to Index short positions when PIMCO deems it appropriate to do so. Additionally, the Fund may purchase call options on Index futures contracts or on other similar Index derivatives in an effort to limit the total potential decline in the Fund's net asset value during a market in which prices of securities are rising or expected to rise. Because the Fund invests primarily in short positions, gains and losses in the Fund will primarily be taxable as short-term gains or losses. However, a portion of the gains or losses from certain types of derivatives, including futures contracts on broad-based stock indexes in which the Fund may choose to invest, will be taxable as long-term gains or losses.

Assets not invested in equity securities or derivatives may be invested in Fixed Income Instruments. PIMCO actively manages the fixed income assets held by the Fund with a view toward enhancing the Fund's total return, subject to an overall portfolio duration which normally varies from (negative) 3 years to positive 8 years based on PIMCO's forecast for interest rates. 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 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 limitation, the Fund may invest in mortgage-related securities rated below B). The Fund may invest, without limitation, in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. The Fund may invest up to 25% of its total assets in securities and instruments that are economically tied to emerging market countries. The Fund will normally limit its foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to 20% of its total assets. The Fund is non-diversified, which means that it may invest its assets in a smaller number of issuers than a diversified fund. The Fund may also invest up to 10% of its total assets in preferred stocks.

Although the Fund uses derivatives and other short positions to gain exposures that may vary inversely with the performance of the Index on a daily basis, the Fund as a whole is not designed or expected to produce returns which replicate the inverse of the performance of the Index, and the degree of variation could be substantial, particularly over longer periods.

Principal Risks

It is possible to lose money on an investment in the Fund. Under certain conditions, even if the value of the Index is declining (which could be beneficial to the Fund's short strategy), this could be offset by declining values of Fixed Income Instruments held by the Fund. Conversely, it is possible that rising fixed income securities prices could be offset by a rising Index (which could lead to losses in a short strategy). In either scenario the Fund may experience losses. In a market where the value of the Index is rising and the Fund's Fixed Income Instrument holdings are declining, the Fund may experience substantial losses. 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

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 and liquidity risks. High yield securities are considered primarily speculative with respect to the issuer's continuing ability to make principal and interest payments

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

Inverse Correlation and Compounding Risk: the risk that the Fund's performance may vary substantially from the inverse performance of the Index for a number of reasons, including the effects of compounding on the performance of the Fund's derivatives short positions for periods greater than one day, the results of PIMCO's active management of the Fund (including income and gains or losses from Fixed Income Instruments and variations in the Fund's level of short exposure) and that derivatives positions in general may not correlate exactly with an index

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

Derivatives Risk: the risk of investing in derivative instruments, including liquidity, interest rate, market, credit and management risks, mispricing or improper valuation. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested

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 Risk: the risk of investing in mortgage-related and other asset-backed securities, including interest rate risk, extension risk and prepayment 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, and 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

Currency Risk: the risk that foreign 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

Issuer Non-Diversification Risk: the risk of focusing investments in a small number of issuers, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. Funds that are "non-diversified" may invest a greater percentage of their assets in the securities of a single issuer (such as bonds issued by a particular state) than funds that are "diversified"

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, causing the Fund to be more volatile than if it had not been leveraged

Management Risk: the risk that the investment techniques and risk analyses applied by PIMCO will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to PIMCO 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.

Performance Information

The Fund measures its performance against two benchmarks. The Fund's primary benchmark is the S&P 500 Index. The Fund's performance may vary inversely with the value of the S&P 500 Index on a daily basis, subject to certain limitations. The Fund's secondary benchmark is the Inverse of S&P 500 Index. The Fund believes that the secondary benchmark reflects the Fund's investment strategy more accurately than the S&P 500 Index. It may be reasonable to expect significant differences between the Fund's performance and that of the secondary benchmark, as well as potentially significant differences between the Fund's primary and secondary benchmarks due to compounding and other considerations.

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 D shares (July 31, 2006), performance information shown in the table for Class D 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 Class D shares. 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 S&P 500 Index is an unmanaged market index generally considered representative of the stock market as a whole. The index focuses on the large-cap segment of the U.S. equities market. The Fund's performance may vary inversely with the value of the index on a daily basis, subject to certain limitations. Effective July 31, 2009, the Fund selected the S&P 500 Index as its primary benchmark in replacement of the Inverse of the S&P 500 Index, which the Fund retains as its secondary benchmark. The Fund added the S&P 500 Index to facilitate a comparison of the Fund's performance to the S&P 500 Index. The Inverse of the S&P 500 Index is the negative equivalent of the return of the S&P 500 Index. The S&P 500 Index is an unmanaged market index generally considered representative of the stock market as a whole. The Index focuses on the large-cap segment of the U.S. equities market. The Lipper Dedicated Short-Bias Fund Average is a total return performance average of funds tracked by Lipper, Inc. that employ portfolio strategies consistently creating a "net short" exposure to the market. This classification also includes short-only funds, i.e., funds that pursue short sales of stock or stock index options. The Fund began operations on 7/23/03. Index comparisons began on 7/31/03.

(1) 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.

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 635% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing primarily in short positions with respect to the S&P 500 Index (the "Index") or specific Index securities, backed by a portfolio of Fixed Income Instruments, such that the Fund's net asset value may vary inversely with the value of the Index on a daily basis, subject to certain limitations summarized below. In managing the Fund's investments in Fixed Income Instruments, PIMCO utilizes an absolute return approach, which is designed to have more discretion 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 fixed income index benchmark. The absolute return approach does not apply to the equity index replicating component of the Fund. "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 Fund will generally benefit when the price of the Index is declining. When the Index is rising, the Fund will generally not perform as well. Fixed Income Instruments owned by the Fund may also benefit or detract from the Fund's net asset value. The Fund is designed for investors seeking to take advantage of declines in the value of the Index, or investors wishing to hedge existing long equity positions. However, the Fund is not designed or expected to produce returns which replicate the inverse of the performance of the Index due to compounding, Pacific Investment Management Company LLC's ("PIMCO") active management, Fund fees and expenses and other factors discussed below.

The Fund will maintain short positions through the use of a combination of derivatives, including options, futures, options on futures, and swaps. The Fund may invest, without limitation, in such instruments. While the Fund will, under normal circumstances, invest primarily in Index short positions backed by a portfolio of Fixed Income Instruments, PIMCO may reduce the Fund's exposure to Index short positions when PIMCO deems it appropriate to do so. Additionally, the Fund may purchase call options on Index futures contracts or on other similar Index derivatives in an effort to limit the total potential decline in the Fund's net asset value during a market in which prices of securities are rising or expected to rise. Because the Fund invests primarily in short positions, gains and losses in the Fund will primarily be taxable as short-term gains or losses. However, a portion of the gains or losses from certain types of derivatives, including futures contracts on broad-based stock indexes in which the Fund may choose to invest, will be taxable as long-term gains or losses.

Principal Risks

It is possible to lose money on an investment in the Fund. Under certain conditions, even if the value of the Index is declining (which could be beneficial to the Fund's short strategy), this could be offset by declining values of Fixed Income Instruments held by the Fund. Conversely, it is possible that rising fixed income securities prices could be offset by a rising Index (which could lead to losses in a short strategy). In either scenario the Fund may experience losses. In a market where the value of the Index is rising and the Fund's Fixed Income Instrument holdings are declining, the Fund may experience substantial losses. 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

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 and liquidity risks. High yield securities are considered primarily speculative with respect to the issuer's continuing ability to make principal and interest payments

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

Inverse Correlation and Compounding Risk: the risk that the Fund's performance may vary substantially from the inverse performance of the Index for a number of reasons, including the effects of compounding on the performance of the Fund's derivatives short positions for periods greater than one day, the results of PIMCO's active management of the Fund (including income and gains or losses from Fixed Income Instruments and variations in the Fund's level of short exposure) and that derivatives positions in general may not correlate exactly with an index

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

Derivatives Risk: the risk of investing in derivative instruments, including liquidity, interest rate, market, credit and management risks, mispricing or improper valuation. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested

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 Risk: the risk of investing in mortgage-related and other asset-backed securities, including interest rate risk, extension risk and prepayment 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, and 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

Currency Risk: the risk that foreign 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

Issuer Non-Diversification Risk: the risk of focusing investments in a small number of issuers, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. Funds that are "non-diversified" may invest a greater percentage of their assets in the securities of a single issuer (such as bonds issued by a particular state) than funds that are "diversified"

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, causing the Fund to be more volatile than if it had not been leveraged

Management Risk: the risk that the investment techniques and risk analyses applied by PIMCO will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to PIMCO 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.

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 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 Class A shares, but does not reflect the impact of sales charges (loads). If it did, the returns would be lower than those shown. Performance in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of Class A and C shares (July 31, 2006), performance information shown in the bar chart and table for these classes is based on the performance of the Fund's Institutional Class shares, which are offered in a different prospectus. The prior Institutional Class performance has been adjusted to reflect the actual sales charges (in the Average Annual Total Returns table only), distribution and/or service (12b-1) fees, administrative fees and other expenses paid by Class A and C shares. The Fund's past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.

The Fund measures its performance against two benchmarks. The Fund's primary benchmark is the S&P 500 Index. The Fund's performance may vary inversely with the value of the S&P 500 Index on a daily basis, subject to certain limitations. The Fund's secondary benchmark is the Inverse of S&P 500 Index. The Fund believes that the secondary benchmark reflects the Fund's investment strategy more accurately than the S&P 500 Index. It may be reasonable to expect significant differences between the Fund's performance and that of the secondary benchmark, as well as potentially significant differences between the Fund's primary and secondary benchmarks due to compounding and other considerations.

The S&P 500 Index is an unmanaged market index generally considered representative of the stock market as a whole. The index focuses on the large-cap segment of the U.S. equities market. The Fund's performance may vary inversely with the value of the index on a daily basis, subject to certain limitations. Effective July 31, 2009, the Fund selected the S&P 500 Index as its primary benchmark in replacement of the Inverse of the S&P 500 Index, which the Fund retains as its secondary benchmark. The Fund added the S&P 500 Index to facilitate a comparison of the Fund's performance to the S&P 500 Index. The Inverse of S&P 500 Index is the negative equivalent of the return of the S&P 500 index. The Index focuses on the large-cap segment of the U.S. equities market. The Lipper Dedicated Short-Bias Fund Average is a total return performance average of funds tracked by Lipper, Inc. that employ portfolio strategies consistently creating a "net short" exposure to the market. This classification also includes short-only funds, i.e., funds that pursue short sales of stock or stock index options. The Fund began operations on 7/23/03. Index comparisons began on 7/31/03.

Performance for the Fund is updated daily and quarterly and may be obtained as follows: daily updates on the net asset value and performance page at http://investments.pimco.com/DailyPerformance and quarterly updates at http://investments.pimco.com/QuarterlyPerformance.

(1) 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 Class A shares only. After-tax returns for other classes will vary.

PIMCO serves as the investment adviser for the Fund. The Fund's portfolio is managed by William H. Gross. Mr. Gross is a Managing Director, Co-Chief Investment Officer and a founding partner of PIMCO and he has managed the Fund since its inception in July 2003.

Purchase and Sale of Fund Shares

The minimum initial investment for Class A and Class C shares of the Fund is $1,000 and $50 for each minimum subsequent investment, except that the minimum initial investment may be modified for certain financial firms that submit orders on behalf of their customers. You may purchase or sell (redeem) all or part of your Fund shares through a broker, dealer, or other financial firm, or directly from the Trust by regular mail to PIMCO Funds, P.O. Box 55060, Boston, MA 02205-5060 or overnight mail to PIMCO Funds, c/o Boston Financial Data Services, Inc., 30 Dan Road, Canton, MA 02021-2809 as further described in the Fund's prospectus.

Tax Information

The Fund's distributions are generally taxable to you as ordinary income, capital gains, or a combination of the two, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account.

Payments to Broker-Dealers and Other Financial Firms

If you purchase shares of a Fund through a broker-dealer or other financial firm (such as a bank), the Fund and/or its related companies (including PIMCO) may pay the financial firm for the sale of those shares of the Fund and/or related services. These payments may create a conflict of interest by influencing the broker-dealer or other financial firm and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial firm's Web site for more information.
