Summary Prospectus July 31, 2010

PIMCO Short Duration Municipal Income Fund

Before you invest, you may want to review the Fund’s prospectus, which contains more information about the Fund and its risks. You can find the Fund’s prospectus and other information about the Fund online at www.pimco-funds.com/prospectuses. You can also get this information at no cost by calling 1-800-927-4648 or by sending an email request to Orders@MySummaryProspectus.com. The Fund’s prospectus and Statement of Additional Information, both dated July 31, 2010, along with the financial statements included in the Fund’s most recent annual report to shareholders dated March 31, 2010, are incorporated by reference into this Summary Prospectus.

INVESTMENT OBJECTIVE

The Fund seeks high current income exempt from federal income tax, consistent with preservation of capital.

FEES AND EXPENSES OF THE FUND

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	0.33	%	0.43	%	0.33	%	0.48	%
Distribution and/or Service (12b-1) Fees	N/A		N/A		0.25	%	0.25	%
Total Annual Fund Operating Expenses	0.33	%	0.43	%	0.58	%	0.73	%

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	$34	$106	$185	$418
Class P	$44	$138	$241	$542
Administrative Class	$59	$186	$324	$726
Class D	$75	$233	$406	$906

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. 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 73% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund seeks to achieve its investment objective by investing under normal circumstances at least 80% of its assets in debt securities whose interest is, in the opinion of bond counsel for the issuer at the time of issuance, exempt from federal income tax (“Municipal Bonds”). Municipal Bonds generally are issued by or on behalf of states and local governments and their agencies, authorities and other instrumentalities.

The Fund does not intend to invest in securities whose interest is subject to the federal alternative minimum tax. The Fund may only invest in investment grade debt securities. The Fund may invest more than 25% of its total assets in bonds of issuers in California and New York. To the extent that the Fund concentrates its investments in California or New York, it will be subject to California or New York State-Specific Risk. The Fund may also invest 25% or more of its total assets in Municipal Bonds that finance education, health care, housing, transportation, utilities and other similar projects, and 25% or more of its total assets in industrial development bonds. The average portfolio duration of this Fund varies based on Pacific Investment Management Company LLC’s (“PIMCO”) forecast for interest rates and under normal market conditions is not expected to exceed three 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 portfolio manager focuses on bonds with the potential to offer attractive current income, typically looking for bonds that can provide consistently attractive current yields or that are trading at competitive market prices.

The Fund may invest in derivative instruments, such as options, futures contracts or swap agreements, or in mortgage- or asset-backed securities. 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 invest in securities issued by entities, such as trusts, whose underlying assets are Municipal Bonds, including, without limitation, residual interest bonds. 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 buy backs or dollar rolls). The Fund may also invest up to 10% of its total assets in preferred stocks.

PIMCO Short Duration Municipal Income 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:

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

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

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 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

California State-Specific Risk: the risk that by concentrating its investments in California Municipal Bonds the Fund may be affected significantly by economic, regulatory or political developments affecting the ability of California issuers to pay interest or repay principal

New York State-Specific Risk: the risk that by concentrating its investments in New York Municipal Bonds the Fund may be affected significantly by economic, regulatory or political developments affecting the ability of New York issuers to pay interest or repay principal

Municipal Project-Specific Risk: the risk that the Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to education, health care, housing, transportation, and utilities), industrial development bonds, or in bonds from issuers in a single state

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 Institutional Class shares. For periods prior to the inception date of Class P shares (April 30, 2008), Administrative Class shares (October 22, 2002) and Class D shares (January 31, 2000), 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. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.

(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.

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.

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 they did, the returns would be lower than those shown. Unlike the bar chart, performance for Class A and Class C shares in the Average Annual Total Returns table reflects the impact of sales charges. For periods prior to the inception date of Class A and Class C shares (March 28, 2002), performance information shown in the bar chart and table 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 and other expenses paid by Class A and Class 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.
