(2)

PIMCO contractually agreed, through July 13, 2013, to waive its supervisory and administrative fee, or reimburse the Fund, to the extent that organizational expenses and pro rata Trustees’ fees exceed 0.0049% of the Fund’s average net assets attributable to Institutional Class, Class P, Administrative Class and Class D shares, respectively (the “Expense Limit”). Under the Expense Limitation Agreement, which renews annually for a full year unless terminated by PIMCO upon at least 30 days’ notice prior to the end of the contract term, PIMCO may recoup these waivers and reimbursements in future periods, not exceeding three years, provided organizational expenses and pro rata Trustees’ fees plus such recoupment, do not exceed the Expense Limit.

(3)	PIMCO has contractually agreed, through July 13, 2013, to waive, first, the advisory fee and, second, the supervisory and administrative fee it receives from the Fund in an amount equal to the expenses attributable to the Management Fees of Underlying PIMCO Funds indirectly incurred by

the Fund in connection with its investments in Underlying PIMCO Funds, to the extent the Fund’s Management Fees are greater than or equal to the Management Fees of the Underlying PIMCO Funds. This waiver renews annually for a full year unless terminated by PIMCO upon at least 30 days’ notice prior to the end of the contract term.

(4)	PIMCO has contractually agreed, through July 31, 2013, to waive a portion of its advisory fee equal to 0.10% of average daily net assets.

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 VII, 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.

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.


	1 Year		3 Years
Institutional Class		$82		$255
Class P		$92		$287
Administrative Class		$107		$334
Class D		$127		$397

PORTFOLIO TURNOVER

LOGO

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. The Fund has not yet commenced operations. Thus, no portfolio turnover is provided for the Fund.

PRINCIPAL INVESTMENT STRATEGIES

LOGO

seeking to achieve the Fund’s investment objective which consists of 1) developing a target asset allocation; 2) developing a series of relative value strategies designed to add value beyond the target allocation; and 3) utilizing hedging techniques to manage risks. PIMCO evaluates these three steps daily and uses varying combinations of Acquired Funds and/or direct investments to implement them within the Fund. The Fund may invest in Institutional Class or Class M shares of any funds of the Trust and PIMCO Equity Series, an affiliated open-end investment company, except funds of funds such as the PIMCO All Asset, PIMCO All Asset All Authority, PIMCO Global Multi-Asset and PIMCO RealRetirement^® Funds (“Underlying PIMCO Funds”), and may also invest in other affiliated, including funds of PIMCO ETF Trust, and unaffiliated funds (collectively, “Acquired Funds”).

The Fund seeks to achieve its investment objective by investing under normal circumstances in a combination of Fixed Income Instruments of varying maturities, equity securities, affiliated and unaffiliated investment companies, which may or may not be registered under the Investment Company Act of 1940, as amended (the “1940 Act”), forwards and derivatives, such as options, futures contracts or swap agreements, of various asset classes in seeking to mitigate the negative effects of inflation. Such asset classes include, but are not limited to, inflation-linked bonds, commodities, emerging market currencies and real estate-related instruments. “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 invest in such funds, securities, instruments and other investments to the extent permitted under the 1940 Act, or any exemptive relief therefrom. The Fund may invest, without limitation, in any of the Underlying PIMCO Funds (except as described below).

The Fund may invest in inflation-indexed bonds of varying maturities issued by the U.S. and non-U.S. governments, their agencies or instrumentalities and corporations. Inflation-indexed bonds are fixed income securities that are structured to provide protection against inflation. The value of the bond’s principal or the interest income paid on the bond is adjusted to track changes in an official inflation measure. The U.S. Treasury uses the Consumer Price Index for Urban Consumers as the inflation measure. Inflation-indexed bonds issued by a foreign government are generally adjusted to reflect a comparable inflation index, calculated by that government. To mitigate the negative effects of inflation, the Fund seeks concurrent exposure to a broad spectrum of asset classes and other investments.

Subsidiary is advised by PIMCO and primarily invests in commodity-linked derivative instruments backed by a portfolio of inflation-indexed securities and other Fixed Income Instruments. As discussed in greater detail elsewhere in this prospectus, the Subsidiary (unlike the Fund) may invest without limitation in commodity-linked swap agreements and other commodity-linked derivative instruments. The Fund may invest up to 25% of its total assets in the Subsidiary. The Fund will normally limit its exposure to gold to 15% of its total assets. The Fund may invest, without limitation, in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. The Fund will normally limit its foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to 25% of its total assets. The Fund may invest, without limitation, in high yield securities (“junk bonds”). The Fund may invest, without limitation, in securities and instruments that are economically tied to emerging market countries.

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 purchase and sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales.

The Fund’s assets are not allocated according to a predetermined blend of shares of the Acquired Funds and/or direct investments in securities, instruments and other investments. Instead, when making allocation decisions among the Acquired Funds, securities, instruments and other investments, PIMCO considers various qualitative and quantitative factors relating to the U.S. and non-U.S. economies, and securities and commodities markets. These factors include projected growth trends in the U.S. and non-U.S. economies, forecasts for interest rates and the relationship between short- and long-term interest rates (yield curve), current and projected trends in inflation, relative valuation levels in the equity, fixed income, commodity and real estate markets and various segments within those markets, the outlook and projected growth of various industrial sectors, information relating to business cycles, borrowing needs and the cost of capital, political trends data relating to trade balances, and labor information. PIMCO uses these factors to help determine the Fund’s target asset allocation and to identify potentially attractive relative value and risk hedging strategies. PIMCO has the flexibility to reallocate the Fund’s assets among any or all of the investment exposures represented by affiliated or unaffiliated funds, or invest directly in securities, instruments and other investments, based on its ongoing analyses of the global economy and financial markets. While these analyses are performed daily, material shifts in investment exposures typically take place over longer periods of time.

Once the target asset allocation, relative value strategies and risk hedging strategies have been determined, PIMCO then evaluates various combinations of affiliated or unaffiliated funds, securities, instruments and other investments to obtain the desired exposures and invests accordingly.

PRINCIPAL RISKS

LOGO

It is possible to lose money on an investment in the Fund. The principal risks of investing in the Fund include risks from direct investments and/or indirect exposure through investment in Acquired Funds. The principal risks of investing in the Fund, which could adversely affect its net asset value, yield and total return are:

Allocation Risk: the risk that a Fund could lose money as a result of less than optimal or poor asset allocation decisions as to how its assets are allocated or reallocated

Acquired Fund Risk: the risk that a 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 a Fund to achieve its investment objective will depend upon the ability of the Acquired Funds to achieve their investment objectives

Equity Risk: the risk that the value of equity or equity-related 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

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 service

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

condemnation, and changes in local and general economic conditions, supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes and operating expenses. A Fund’s investments in REITs or real estate-linked derivative instruments subject it to management and tax risks

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 managers 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

Mortgage-Related and Other Asset-Backed Risk: the risks of Investing in mortgage-related and other asset-backed securities, including interest rate risk, extension risk and prepayment risk

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

Convertible Securities Risk: as convertible securities share both fixed income and equity characteristics, they are subject to risks to which fixed income and equity investments are subject. These risks include equity risk, interest rate risk and credit risk

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

Issuer Non-Diversification Risk: the risks 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”

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.

PRINCIPAL INVESTMENT STRATEGIES

LOGO

The Fund is intended for investors who prefer to have their asset allocation decisions made by professional investment managers. Pacific Investment Management Company LLC (“PIMCO”) uses a three-step approach in seeking to achieve the Fund’s investment objective which consists of 1) developing a target asset allocation; 2) developing a series of relative value strategies designed to add value beyond the target allocation; and 3) utilizing hedging techniques to manage risks. PIMCO evaluates these three steps daily and uses varying combinations of Acquired Funds and/or direct investments to implement them within the Fund.

The Fund may invest in Institutional Class or Class M shares of any funds of the Trust and PIMCO Equity Series, an affiliated open-end investment company, except funds of funds such as the PIMCO All Asset, PIMCO All Asset All Authority, PIMCO Global Multi-Asset and PIMCO RealRetirement^® Funds (“Underlying PIMCO Funds”), and may also invest in other affiliated, including funds of PIMCO ETF Trust, and unaffiliated funds (collectively, “Acquired Funds”).

The Fund may invest up to 25% of its total assets in equity-related investments (including investment in common stock, preferred stock, equity securities of Real Estate Investment Trusts (“REITs”) and/or investment in the Domestic Equity-Related Underlying PIMCO Funds, the International Equity-Related Underlying PIMCO Funds and the PIMCO RealEstateRealReturn Strategy Fund, an Underlying PIMCO Fund and in other equity-related Acquired Funds) and the Fund may invest up to 15% of its total assets in equity securities of REITs. With respect to its direct or indirect (through a fund) investments in equity securities, there is no limitation on the market capitalization range of the issuers in which the Fund may invest. The Fund may invest up to 50% of its total assets in commodity-related investments (including investment in the PIMCO Cayman Commodity Fund VII, Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the “Subsidiary”), and the PIMCO CommoditiesPLUS^™ Short Strategy Fund, PIMCO CommoditiesPLUS^™ Strategy Fund and PIMCO Commodity RealReturn Strategy Fund^®, each an Underlying PIMCO Fund). The Subsidiary is advised by PIMCO and primarily invests in commodity-linked derivative instruments backed by a portfolio of inflation-indexed securities and other Fixed Income Instruments. As discussed in greater detail elsewhere in this prospectus, the Subsidiary (unlike the Fund) may invest without limitation in commodity-linked swap agreements and other commodity-linked derivative instruments. The Fund may invest up to 25% of its total assets in the Subsidiary. The Fund will normally limit its exposure to gold to 15% of its total assets. The Fund may invest, without limitation, in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. The Fund will normally limit its foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to 25% of its total assets. The Fund may invest, without limitation, in high yield securities (“junk bonds”). The Fund may invest, without limitation, in securities and instruments that are economically tied to emerging market countries.
