You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Class A shares of eligible funds offered by PIMCO Equity Series and PIMCO Funds. More information about these and other discounts is available in the "Classes of Shares" section on page 39 of the Fund's prospectus or from your financial advisor.

Acquired Fund Fees and Expenses	0.02%	0.02%	0.02%	0.02%	0.02%	0.02%	0.02%
Total Annual Fund Operating Expenses ² ^,3	1.08%	1.18%	1.33%	1.43%	1.43%	2.18%	1.68%
Fee Waiver and/or Expense Reimbursement ⁴ ^,5 ^,6	(0.18%)	(0.18%)	(0.18%)	(0.18%)	(0.18%)	(0.18%)	(0.18%)
Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement ⁷	0.90%	1.00%	1.15%	1.25%	1.25%	2.00%	1.50%

"Other Expenses" reflect interest expense and dividends paid on borrowed securities. Interest expense results from the Fund's use of certain investments such as reverse repurchase agreements. Dividends paid on borrowed securities are an expense of short sales. Such expenses are required to be treated as a Fund expense for accounting purposes and are not payable to PIMCO. Any interest expense amount or dividends paid on securities sold short 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 do not match the Ratio of Expenses to Average Net Assets of the Fund, as set forth in the Financial Highlights table of the Fund's prospectus, because the Ratio of Expenses to Average Net Assets reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

³	Total Annual Fund Operating Expenses excluding interest expense and dividends paid on borrowed securities is 1.07%, 1.17%, 1.32%, 1.42%, 1.42%, 2.17% and 1.67% for Institutional Class, Class P, Administrative Class, Class D, Class A, Class C and Class R shares, respectively.

⁴

PIMCO has contractually agreed, through October 31, 2014, to reduce its advisory fee by 0.16% of the average daily net assets of the Fund. This Fee Limitation Agreement renews annually unless terminated by PIMCO upon at least 30 days' prior notice to the end of the contract term. Under certain conditions, PIMCO may recoup amounts reduced in future periods, not exceeding three years.

⁵

PIMCO has contractually agreed to waive the Fund's advisory fee and the supervisory and administrative fee in an amount equal to the management fee and administrative services fee, respectively, paid by the PIMCO Cayman Commodity Fund VI, Ltd. (the "Subsidiary") to PIMCO. The Subsidiary pays PIMCO a management fee and an administrative services fee at the annual rates of 0.49% and 0.20%, respectively, of its net assets. This waiver may not be terminated by PIMCO and will remain in effect for as long as PIMCO's contract with the Subsidiary is in place.

⁶

Certain fees and expenses are not waived or reimbursed, such as direct or indirect (through an acquired fund) interest expense or dividends paid on borrowed securities, and the expense of investing in acquired funds other than certain PIMCO funds. The amount of such expenses will vary based on the Fund's use of those investments as an investment strategy best suited to seek the objective of the Fund.

⁷

Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement excluding interest expense and dividends paid on borrowed securities is 0.89%, 0.99%, 1.14%, 1.24%, 1.24%, 1.99% and 1.49% for Institutional Class, Class P, Administrative Class, Class D, Class A, Class C and Class R shares, respectively.

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

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

	1 Year	3 Years	5 Years	10 Years
Institutional Class	$92	$287	$498	$1,108
Class P	$102	$318	$552	$1,225
Administrative Class	$117	$365	$633	$1,398
Class D	$127	$397	$686	$1,511
Class A	$670	$925	$1,199	$1,978
Class C	$303	$627	$1,078	$2,327
Class R	$153	$474	$818	$1,791

If you do not redeem your shares:

	1 Year	3 Years	5 Years	10 Years
Institutional Class	$92	$287	$498	$1,108
Class P	$102	$318	$552	$1,225
Administrative Class	$117	$365	$633	$1,398
Class D	$127	$397	$686	$1,511
Class A	$670	$925	$1,199	$1,978
Class C	$203	$627	$1,078	$2,327
Class R	$153	$474	$818	$1,791

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 29% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing under normal circumstances in equity securities, including common and preferred stock (and securities convertible into, or that Pacific Investment Management Company LLC ("PIMCO") expects to be exchanged for, common or preferred stock), of issuers that PIMCO believes are undervalued. The Fund's bottom-up value investment style attempts to identify securities that are undervalued by the market in comparison to PIMCO's own determination of the company's value, taking into account criteria such as asset value, book value and cash flow and earnings estimates.

When making investments, PIMCO evaluates the merits of each investment separately and there are no specific limitations on the value, asset size, earnings or industry classification of the Fund's investments. The Fund may invest in securities issued by large-capitalization, mid-capitalization and small-capitalization companies. The Fund generally considers large- and mid-cap companies to be those with market capitalizations greater than $1.5 billion. The Fund may invest, without limitation, in securities and instruments that are economically tied to foreign (non-U.S.) countries. The Fund may also invest in securities and instruments that are economically tied to emerging market countries.

The Fund may also invest in U.S. and non-U.S. sovereign government debt and other debt securities, including bank loans, that PIMCO selects on the basis of its determination of the security's value and not necessarily based on the coupon rate or credit rating of the security. The debt investments of the Fund may include high yield securities ("junk bonds") of any rating. The Fund may invest in the securities of distressed companies including defaulted securities, which typically involve investments in lower-rated debt securities and loans but may also include equity securities of distressed companies.

The Fund may invest in commodity-related investments. The Fund will seek to gain exposure to the commodity futures markets primarily through investments in the PIMCO Cayman Commodity Fund VI, Ltd., a wholly owned subsidiary of the Fund organized under the laws of the Cayman Islands (the "Subsidiary"). The Subsidiary is advised by PIMCO, and has the same investment objective as the Fund. As discussed in greater detail elsewhere in the prospectus, the Subsidiary (unlike the Fund) may invest without limitation in commodity index-linked swap agreements and other commodity-linked derivative instruments.

The Fund may engage in a risk arbitrage strategy to take advantage of a perceived relationship between the value of two securities. Under an arbitrage strategy, the Fund may purchase one security while selling short another security. The security purchased is generally considered by PIMCO to be undervalued relative to the price of the security sold short, or the security sold short is generally considered to be overvalued relative to the price of the security purchased. Issuers of securities acquired pursuant to an arbitrage strategy may be engaged in certain types of corporate events, such as restructurings, acquisitions, mergers, takeovers, tender or exchange offers or liquidations. The Fund may attempt to hedge foreign currency exposure using foreign currency exchange contracts and other investments and may utilize derivative instruments to hedge against other market risks. The Fund may also invest in derivative instruments, such as options, futures contracts or swap agreements consistent with its investment objective. 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 enter into reverse repurchase agreements and lend portfolio securities.

The Fund may purchase securities to seek to influence or control management of an issuer, or may invest in other companies that do so, when the portfolio managers believe such actions would benefit the Fund.

Principal Risks

It is possible to lose money on an investment in the Fund. The principal risks of investing in the Fund, which could adversely affect its net asset value, yield and total return are:

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

Value Investing Risk: a value stock may decrease in price or may not increase in price as anticipated by PIMCO if it continues to be undervalued by the market or the factors that PIMCO believes will cause the stock price to increase do not occur

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

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 reasons directly related to the issuer, such as management performance, financial leverage and reduced demand for the issuer's goods or services

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 and Distressed Company Risk: the risk that high yield securities and unrated securities of similar credit quality (commonly known as "junk bonds") and securities of distressed companies may be subject to greater levels of credit, issuer and liquidity risks. Securities of distressed companies include both debt and equity securities. High yield securities and debt securities of distressed companies are considered primarily speculative with respect to the issuer's continuing ability to make principal and interest payments. Distressed companies may be engaged in restructurings or bankruptcy proceedings

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

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

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

Small-Cap and Mid-Cap Company Risk: the risk that the value of securities issued by small-capitalization and mid-capitalization companies may go up or down, sometimes rapidly and unpredictably, due to narrow markets and limited managerial and financial resources

Arbitrage Risk: the risk that securities purchased pursuant to an arbitrage strategy intended to take advantage of a perceived relationship between the value of two securities may not perform as expected

Derivatives Risk: the risk of investing in derivative instruments, including liquidity, 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

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

Commodity Risk: the risk that investing in commodity-linked derivative instruments may subject the Fund to greater volatility than investments in traditional securities. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments

Tax Risk: the risk that the tax treatment of swap agreements and other derivative instruments, such as commodity-linked derivative instruments, including commodity index-linked notes, swap agreements, commodity options, futures, and options on futures, may be affected by future regulatory or legislative changes that could affect the character, timing and/or amount of the Fund's taxable income or gains and distributions

Subsidiary Risk: the risk that, by investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary's investments. There is no guarantee that the investment objective of the Subsidiary will be achieved

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. Absent any applicable fee waivers and/or expense limitations, performance would have been lower. The bar chart shows performance of the Institutional Class shares. Performance for Class A and Class C shares 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 Fund's benchmark is the MSCI World Index. The MSCI World Index is a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed markets. The MSCI World Index consists of 24 developed market country indices.

(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.

Payments to Broker-Dealers and Other Financial Firms

If you purchase shares of the 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.

Ask your salesperson or visit your financial firm's Web site for more information.
