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. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in Class A shares of eligible funds offered by Allianz Funds, Allianz Multi-Strategy Funds, PIMCO Equity Series and PIMCO Funds. Effective April 11, 2011, purchases of the funds offered by Allianz Funds and Allianz Multi-Strategy Funds are no longer eligible to qualify for sales charge discounts. More information about these and other discounts is available in the “Classes of Shares—Class A and C Shares” section on page 10 of the Fund’s prospectus or from your financial advisor.

Shareholder Fees (fees paid directly from your investment)

	Class A			Class C
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)		5.50	%		NONE
Maximum Deferred Sales Charge (Load) (as a percentage of the lower of the original purchase price or redemption price)		1.00	%		1.00	%

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

	Class A		Class C
Management Fees		0.80%		0.80%
Distribution and/or Service (12b-1) Fees		0.25%		1.00%
Total Annual Fund Operating Expenses		1.05%		1.80%

Example The Example is intended to help you compare the cost of investing in Class A or Class C 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
Class A		$651		$866		$1,098		$1,762
Class C		$283		$566		$975		$2,116

If you do not redeem your shares:

	1 Year		3 Years		5 Years		10 Years
Class A		$651		$866		$1,098		$1,762
Class C		$183		$566		$975		$2,116

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 203% 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 a diversified portfolio of convertible securities, which may be represented by forwards or derivatives such as options, futures contracts or swap agreements. Convertible securities, which are issued by companies of all sizes and market capitalizations, include, but are not limited to: corporate bonds, debentures, notes or preferred stocks and their hybrids that can be converted into (exchanged for) common stock or other securities, such as warrants or options, which provide an opportunity for equity participation. Convertible securities also include “synthetic” convertible securities. Synthetic convertible securities, which may be created by a third party or PIMCO Investment Management Company LLC (“PIMCO”), are instruments that combine (i) non-convertible fixed income securities or preferred stocks, which may be represented by derivative instruments and (ii) securities or instruments such as warrants or call options that together possess economic characteristics similar to a convertible security. The Fund may invest in securities of any market capitalization, and may from time to time invest a significant amount of its assets in securities of smaller companies.

PIMCO Convertible Fund

The Fund may invest in both investment-grade securities and high yield securities (“junk bonds”) subject to a maximum of 20% of its total assets in securities rated below B 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 also 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 15% of its total assets in securities and instruments that are economically tied to emerging market countries. In addition, the Fund may invest in common stock or in 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, 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. The Fund may also invest directly in real estate investment trusts (“REITs”). 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 “total return” sought by the Fund consists of income earned on the Fund’s investments, plus capital appreciation, if any, which generally arises from decreases in interest rates, foreign currency appreciation, or improving credit fundamentals for a particular sector or security. The Fund may also invest up to 10% of its total assets in preferred stocks.

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

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

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 Fund’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

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

Smaller Company Risk: the risk that the value of securities issued by a smaller company may go up or down, sometimes rapidly and unpredictably as compared to more widely held securities, due to narrow markets and limited resources of smaller companies. A Fund’s investments in smaller companies subject it to greater levels of credit, market and issuer risk

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

Summary Prospectus

Convertible Securities Risk: the risk that the market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. A convertible security’s market value, however, tends to reflect the market price of the common stock of the issuing company when that stock price approaches or is greater than the convertible security’s “conversion price.” The value of a synthetic convertible security will respond differently to market fluctuations than a traditional convertible security because a synthetic convertible is composed of two or more separate securities or instruments, each with its own market value. If the value of the underlying common stock or the level of the index involved in the convertible component falls below the exercise price of the warrant or option, the warrant or option may lose all value

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 they did, the returns would be lower than those shown. Unlike the bar chart, performance for Class A and C shares in the Average Annual Total Returns table reflects the impact of sales charges. In both the bar chart and Average Annual Total Returns table, for periods when Class A and C shares of the Fund were not operational (including February 1, 2003 through April 27, 2011), performance information shown for that class 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 that class 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.

BofA Merrill Lynch All Convertibles Index is an unmanaged index market comprised of convertible bonds and preferred securities. Lipper Convertible Securities Fund Average is a total return performance average of Funds tracked by Lipper, Inc. that invest primarily in convertible bonds and/or convertible preferred stock.

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.

PAYMENTS TO BROKER-DEALERS AND

OTHER FINANCIAL INTERMEDIARIES

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Class A or Class C shares of the Fund and related services.
