FEES AND EXPENSES OF THE FUND

LOGO

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund:

Shareholder Fees (fees paid directly from your investment): None

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


	Institutional Class		Class P		Administrative Class		Class D
Management Fees	0.74	%	0.84	%	0.74	%	0.89	%
Distribution and/or Service (12b-1) Fees	N/A		N/A		0.25	%	0.25	%
Other Expenses⁽¹⁾	0.20	%	0.03	%	0.20	%	0.13	%
Total Annual Fund Operating Expenses⁽²⁾	0.94	%	0.87	%	1.19	%	1.27	%

(1)

“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.

(2)	Total Annual Fund Operating Expenses excluding interest expense is 0.74%, 0.84%, 0.99% and 1.14% for Institutional Class, Class P, Administrative Class and Class D, 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.


	1 Year	3 Years	5 Years	10 Years
Institutional Class	$96	$300	$520	$1,155
Class P	$89	$278	$482	$1,073
Administrative Class	$121	$378	$654	$1,443
Class D	$129	$403	$697	$1,534

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. During the most recent fiscal year, the Fund’s portfolio turnover rate was 863% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

LOGO

The Fund seeks to achieve its investment objective by investing under normal circumstances in real estate-linked derivative instruments backed by a portfolio of inflation-indexed securities and other Fixed Income 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 may invest in real estate-linked derivative instruments, including swap agreements, options, futures, options on futures and structured notes. The value of real estate-linked derivative instruments may be affected by risks similar to those associated with direct ownership of real estate. Real estate values can fluctuate due to losses from casualty or condemnation, and changes in local and general economic conditions, supply and demand, interest rates, property tax rates, regulatory limitations on rents, zoning laws and operating expenses. The Fund may also invest directly in real estate investment trusts (“REIT”) and in common and preferred stocks as well as convertible securities of issuers in real estate-related industries. The Fund may also invest in exchange traded funds.

The Fund typically will seek to gain exposure to the real estate market by investing in REIT total return swap agreements. In a typical REIT swap agreement, the Fund will receive the price appreciation (or depreciation) of a REIT index or portion of an index, from the counterparty to the swap agreement in exchange for paying the counterparty an agreed-upon fee. Investments in REIT swap agreements may be susceptible to additional risks, similar to those associated with direct investment in REITs, including changes in the value of underlying properties, defaults by borrowers or tenants, revisions to the Internal Revenue Code of 1986, as amended (the “Code”), changes in interest rates and poor performance by those managing the REITs. Assets not invested in real estate-linked derivative instruments may be invested in inflation-indexed securities and other Fixed Income Instruments, including derivative Fixed Income Instruments. In addition, Index derivatives may be purchased with a fraction of the assets that would be needed to purchase the securities directly, so that the

remainder of the assets may be invested in Fixed Income Instruments. The Fund is non-diversified, which means that it may invest its assets in a smaller number of issuers than a diversified fund.

The average portfolio duration of the fixed income portion of this Fund will vary based on Pacific Investment Management Company LLC’s (“PIMCO”) forecast for interest rates and under normal market conditions is not expected to exceed ten years. Duration is a measure of the expected life of a fixed income security that is used to determine the sensitivity of a security’s price to changes in interest rates. The Fund may invest up to 10% of its total assets in high yield securities (“junk bonds”) rated B or higher by Moody’s, or equivalently rated by S&P or Fitch, or, if unrated, determined by PIMCO to be of comparable quality. The Fund may invest up to 30% of its total assets in securities denominated in foreign currencies and may invest beyond this limit in U.S. dollar denominated securities of foreign issuers. The Fund may invest up to 10% 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 may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as buybacks or dollar rolls). The Fund may also invest up to 10% of its total assets in preferred stocks. 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.

PRINCIPAL RISKS

LOGO

It is possible to lose money on an investment in the Fund. Under certain conditions, generally in a market where the value of both real estate derivatives and fixed income securities 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 reasons directly related to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods or service

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 risks 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

Real Estate Risk: the risk that a Fund’s investments in Real Estate Investment Trusts (“REITs”) or real estate-linked derivative instruments will subject the Fund to risks similar to those associated with direct ownership of real estate, including losses from casualty or 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 Funds’s investments in REITs or real estate-linked derivative instruments subject it to management and tax risks

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 risks of focusing investments in a small number of issuers, industries or foreign currencies, 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

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

LOGO

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 risk 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 (April 30, 2008), performance information shown in the table for Class P 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 P 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.

Dow Jones U.S. Select Real Estate Investment Trust (REIT) Total Return Index is a subset of the Dow Jones Americas Select Real Estate Securities Index (RESI) and includes only REITs and REIT-like securities. The objective of the index is to measure the performance of publicly traded real estate securities. The indexes are designed to serve as proxies for direct real estate investment, in part by excluding companies whose performance may be driven by factors other than the value of real estate. Lipper Real Estate Funds Average is a total return performance average of Funds tracked by Lipper, Inc, that invests at least 65% of its portfolio in equity securities of domestic and foreign companies engaged in the real estate industry. The Fund began operations on 10/30/03. Index comparisons began on 10/31/03.

(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.
