Example. The Example is intended to help you compare the cost of investing in Institutional Class, I-2, I-3, 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. Investors may pay brokerage commissions on their purchases and sales of Institutional Class, I-2 or I-3 shares of the Fund, which are not reflected in the Example. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 75% of the average value of its portfolio.

Principal Investment Strategies

The Fund's investment objective is maximum total return, consistent with preservation of capital and prudent investment management. The Fund seeks to achieve its investment objective by investing under normal circumstances at least 80% of its assets in currencies of, or Fixed Income Instruments denominated in the currencies of, emerging market countries and in Fixed Income Instruments, each of which may be represented by forwards or derivatives such as options, futures contracts or swap agreements. "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 forwards or derivatives denominated in any currency, and forwards or derivatives denominated in any currency will be included under the 80% of assets policy noted above so long as the underlying asset of such forwards or derivatives is a currency of an emerging market country, a Fixed Income Instrument denominated in the currency of an emerging market country, or a Fixed Income Instrument. The Fund may, but is not required to, hedge its exposure to non-U.S. currencies. Assets not invested in currencies of emerging market countries, Fixed Income Instruments denominated in currencies of emerging market countries, or Fixed Income Instruments, each as described above, may be invested in other types of instruments.

The Fund may invest without limitation in Fixed Income Instruments that are economically tied to emerging market countries. Pacific Investment Management Company LLC ("PIMCO") has broad discretion to identify countries that it considers to qualify as emerging markets. PIMCO will select the Fund's country and currency composition based on its evaluation of relative interest rates, inflation rates, exchange rates, monetary and fiscal policies, trade and current account balances, legal and political developments and other specific factors PIMCO believes to be relevant. The Fund likely will concentrate its investments in Asia, Africa, the Middle East, Latin America and the developing countries of Europe. The Fund may invest in instruments whose return is based on the return of an emerging market security such as a derivative instrument, rather than investing directly in emerging market securities.

The average portfolio duration of this Fund normally varies within two years (plus or minus) of the portfolio duration of the securities comprising the JPMorgan Government Bond Index-Emerging Markets Global Diversified Index (Unhedged), as calculated by PIMCO, which as of May 31, 2018 was 5.12 years. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates.

The Fund may invest in both investment-grade securities and high yield securities ("junk bonds") subject to a maximum of 15% of its total assets in securities rated below B by Moody's Investors Service, Inc. ("Moody's"), or equivalently rated by Standard & Poor's Ratings Services ("S&P") or Fitch, Inc. ("Fitch"), or, if unrated, determined by PIMCO to be of comparable quality. 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 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 and 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 securities.

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 listed below.

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

Call Risk: the risk that an issuer may exercise its right to redeem a fixed income security earlier than expected (a call). Issuers may call outstanding securities prior to their maturity for a number of reasons (e.g., declining interest rates, changes in credit spreads and improvements in the issuer's credit quality). If an issuer calls a security that the Fund has invested in, the Fund may not recoup the full amount of its initial investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable features

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, call and liquidity risks. High yield securities are considered primarily speculative with respect to the issuer's continuing ability to make principal and interest payments, and may be more volatile than higher-rated securities of similar maturity

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

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. Liquidity risk may result from the lack of an active market, reduced number and capacity of traditional market participants to make a market in fixed income securities, and may be magnified in a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, causing increased supply in the market due to selling activity

Derivatives Risk: the risk of investing in derivative instruments (such as futures, swaps and structured securities), including leverage, liquidity, interest rate, market, credit and management risks, mispricing or valuation complexity. Changes in the value of the derivative may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and the Fund could lose more than the initial amount invested. The Fund's use of derivatives may result in losses to the Fund, a reduction in the Fund's returns and/or increased volatility. Over-the-counter ("OTC") derivatives are also subject to the risk that a counterparty to the transaction will not fulfill its contractual obligations to the other party, as many of the protections afforded to centrally-cleared derivative transactions might not be available for OTC derivatives. For derivatives traded on an exchange or through a central counterparty, credit risk resides with the Fund's clearing broker, or the clearinghouse itself, rather than with a counterparty in an OTC derivative transaction. Changes in regulation relating to a mutual fund's use of derivatives and related instruments could potentially limit or impact the Fund's ability to invest in derivatives, limit the Fund's ability to employ certain strategies that use derivatives and/or adversely affect the value of derivatives and the Fund's performance

Equity Risk: the risk that the value of equity securities, such as common stocks and preferred 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 securities generally have greater price volatility than fixed income securities

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

Real Estate Risk: the risk that the 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. The Fund's investments in REITs or real estate-linked derivative instruments subject it to management and tax risks. In addition, privately traded REITs subject the Fund to liquidity and valuation risk

Emerging Markets Risk: the risk of investing in emerging market securities, primarily increased foreign (non-U.S.) investment risk

Sovereign Debt Risk: the risk that investments in fixed income instruments issued by sovereign entities may decline in value as a result of default or other adverse credit event resulting from an issuer's inability or unwillingness to make principal or interest payments in a timely fashion

Currency Risk: the risk that foreign (non-U.S.) currencies will change 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 risk 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"

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, magnifying gains and losses and causing the Fund to be more volatile than if it had not been leveraged. This means that leverage entails a heightened risk of loss

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 restrictions, policies or 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 Exposure 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 will not fulfill its contractual obligations, 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 the I-2 shares (May 30, 2008), performance information shown in the table for that class is based on the performance of the Fund's Institutional Class shares, adjusted to reflect the fees and expenses paid by that class of shares. Performance for Class A and Class C shares in the Average Annual Total Returns table reflects the impact of sales charges. Because I-3 shares of the Fund had not commenced operations as of December 31, 2017, no performance for I-3 shares is provided. The Fund's past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.

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.

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.

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 listed below.

Emerging Markets Risk: the risk of investing in emerging market securities, primarily increased foreign (non-U.S.) investment risk

Performance Information

The Fund's benchmark index is the JPMorgan Corporate Emerging Markets Bond Index Diversified (CEMBI). The index is a uniquely weighted version of the CEMBI index. It limits the weights of those index countries with larger corporate debt stocks by only including a specified portion of these countries' eligible current face amounts of debt outstanding. The CEMBI Diversified results in well-distributed, more balanced weightings for countries included in the index. The countries covered in the CEMBI Diversified are identical to those covered by the CEMBI. The Lipper Emerging Market Hard Currency Debt Funds Average is a total return performance average of funds tracked by Lipper, Inc. that seeks either current income or total return by investing at least 65% of total assets in emerging market debt securities, where "emerging market" is defined by a country's GNP per capita or other economic measures.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing under normal circumstances at least 80% of its assets in currencies of, or in Fixed Income Instruments denominated in the currencies of, emerging market countries, and in short-term investments. The Fund's investments in currencies or Fixed Income Instruments, including short-term investments, may be represented by forwards or derivatives such as options, futures contracts or swap agreements. The Fund may, but is not required to, hedge its exposure to non-U.S. currencies. Assets not invested in currencies or instruments denominated in currencies of emerging market countries or in short-term investments may be invested in other types of 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 the currencies and Fixed Income Instruments of emerging market countries. Pacific Investment Management Company LLC ("PIMCO") has broad discretion to identify countries that it considers to qualify as emerging markets. PIMCO will select the Fund's country and currency composition based on its evaluation of relative interest rates, inflation rates, exchange rates, monetary and fiscal policies, trade and current account balances, legal and political developments and other specific factors PIMCO believes to be relevant. The Fund likely will concentrate its investments in Asia, Africa, the Middle East, Latin America and the developing countries of Europe. The Fund may invest in instruments whose return is based on the return of an emerging market security or a currency of an emerging market, such as a derivative instrument, rather than investing directly in emerging market securities or currencies.

The average portfolio duration of this Fund varies based on PIMCO's market forecasts and, under normal market conditions, is not expected to exceed two years. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates. In addition, the dollar-weighted average maturity of the portion of the Fund's portfolio comprised of short-term investments, under normal circumstances, is expected not to exceed three years.

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 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 primary and a secondary 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 I-2 shares (April 30, 2008), performance information shown in the table for that class is based on the performance of the Fund's Institutional Class shares, adjusted to reflect the fees and expenses paid by that class of shares. Performance for Class A shares in the Average Annual Total Returns table reflects the impact of sales charges. The Fund's past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.

Principal Investment Strategies

The Fund is designed to provide dynamic exposure to a broad range of emerging market fixed income asset classes, such as external debt obligations of sovereign, quasi-sovereign, and corporate entities; currencies, and local currency-denominated obligations of sovereigns, quasi-sovereigns, and corporate issuers. PIMCO uses a three-step active management approach in seeking to achieve the Fund's investment objective: 1) develop a target asset allocation to implement across the eligible investments; 2) identify additional opportunities for country and security selection designed to add value beyond the target asset allocation within each of the eligible investments; and 3) employ additional investment strategies designed to either mitigate or emphasize risks resulting from the implementation of the target asset allocation. This active management approach is driven by PIMCO's global macroeconomic views, emerging markets expertise and experience across a wide range of investment instruments. The Fund's assets are allocated in a manner that reflects PIMCO's views regarding the attractiveness of key investment risk factors, considering both return potential and volatility, and includes an assessment of aggregate country, issuer and currency exposures.

PIMCO evaluates these three steps daily and uses varying combinations of Acquired Funds (defined below) and/or direct investments in efforts to achieve the most efficient execution of PIMCO's investment views. Specifically, "Acquired Funds" refers to the following: funds of the Trust and funds of PIMCO Equity Series and PIMCO ETF Trust, affiliated open-end investment companies, except funds of funds ("Underlying PIMCO Funds") and other affiliated and unaffiliated funds in which the Fund may invest. Acquired Funds may or may not be registered under the Investment Company Act of 1940 (the "1940 Act"). To the extent Underlying PIMCO Funds of the Trust or PIMCO Equity Series are held, Institutional Class or Class M shares will be held. The Fund's investments may also include Fixed Income Instruments of varying maturities, forwards or derivatives, such as options, futures contracts or swap agreements. "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 invests under normal circumstances at least 80% of its assets in investments economically tied to emerging market countries and 80% of its assets in Fixed Income Instruments, which may be represented by direct or indirect (through an Acquired Fund) investments. The Fund may invest, without limitation, in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. In addition, the Fund may invest in both investment-grade securities and high yield securities ("junk bonds") rated at least Caa by Moody's Investors Service, Inc. ("Moody's"), or equivalently rated by Standard & Poor's Rating Services ("S&P") or Fitch, Inc. ("Fitch"), or, if unrated, determined by PIMCO to be of comparable quality. The Fund's benchmark index is a blend of 50% JPMorgan Global Bond Index Emerging Markets- Global Diversified, 25% JPMorgan Emerging Markets Bond Index Global and 25% JPMorgan Corporate Emerging Markets Bond Index Diversified (the "Benchmark"). The Fund will normally limit its foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to between 20% and 80% of its assets. The average portfolio duration of this Fund normally varies within two years (plus or minus) of the portfolio duration of the securities comprising the Benchmark, as calculated by PIMCO, which as of May 31, 2018 was 5.27 years. 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 investment exposures or mix of instruments. 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, unless in response to a perceived short-term opportunity or market dislocation. 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.

Additional information for the Underlying PIMCO Funds can be found in the Statement of Additional Information and/ or the Underlying PIMCO Funds' prospectuses and financial reports. Additional Underlying PIMCO Funds may be added or deleted in the future without shareholder notification.

Principal Risks

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 listed below.

The following risks are principal risks of investing in the Fund.

Allocation Risk: the risk that a Fund could lose money as a result of less than optimal or poor asset allocation decisions. The Fund could miss attractive investment opportunities by underweighting markets that subsequently experience significant returns and could lose value by overweighting markets that subsequently experience significant declines

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

The following are principal risks of investing in the Fund that include risks from direct investments and/or indirect exposure through investment in Acquired Funds.

New/Small Fund Risk: the risk that a new or smaller Fund's performance may not represent how the Fund is expected to or may perform in the long term. In addition, new Funds have limited operating histories for investors to evaluate and new and smaller Funds may not attract sufficient assets to achieve investment and trading efficiencies

Distressed Company Risk: the risk that securities of distressed companies may be subject to greater levels of credit, issuer and liquidity risk than a portfolio that does not invest in such securities. Securities of distressed companies include both debt and equity securities. Debt securities of distressed companies are considered predominantly speculative with respect to the issuers' continuing ability to make principal and interest payments

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

Emerging Markets Risk: the risk of investing in emerging market securities, primarily increased foreign (non-U.S.) investment risk

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

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 whether income from such investments is "qualifying income" under Subchapter M of the Internal Revenue Code, or otherwise 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 certain Underlying PIMCO Funds that invest in a subsidiary (each a "Subsidiary"), the Fund is indirectly exposed to the risks associated with a Subsidiary's investments. The Subsidiaries are not registered under the 1940 Act and may not be subject to all the investor protections of the 1940 Act. There is no guarantee that the investment objective of a Subsidiary will be achieved

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 the portfolio manager believes will cause the stock price to increase do not occur

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

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

Exchange-Traded Fund Risk: the risk that an exchange-traded fund may not track the performance of the index it is designed to track, among other reasons, because of exchange rules, market prices of shares of an exchange-traded fund may fluctuate rapidly and materially, or shares of an exchange-traded fund may trade significantly above or below net asset value, any of which may cause losses to the Fund invested in the exchange-traded fund

Performance Information

The Fund's benchmark index is a blend of 50% JPMorgan Global Bond Index Emerging Markets- Global Diversified, 25% JPMorgan Emerging Markets Bond Index Global and 25% JPMorgan Corporate Emerging Market Bond Index Diversified.

It limits the weights of those index countries with larger debt stocks by only including specified portions of these countries' eligible current face amounts of debt outstanding. The JPMorgan Emerging Markets Bond Index Global tracks total returns for U.S. dollar-denominated debt instruments issued by emerging market sovereign and quasi-sovereign entities: Brady bonds, loans, and Eurobonds. JPMorgan Corporate Emerging Market Bond Index Diversified tracks total returns of U.S. dollar-denominated debt instruments issued by corporate entities in Emerging Markets countries. The Lipper Emerging Market Hard Currency Debt Funds Average is a total return performance average of funds tracked by Lipper, Inc. that seeks either current income or total return by investing at least 65% of total assets in emerging market debt securities, where "emerging market" is defined by a country's GNP per capita or other economic measures.

Principal Investment Strategies

PIMCO selects the Fund's foreign country and currency compositions based on an evaluation of various factors, including, but not limited to, relative interest rates, exchange rates, monetary and fiscal policies, and trade and current account balances. The Fund may invest without limitation in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. The Fund may invest, without limitation, in securities and instruments that are economically tied to emerging market countries. The Fund may also invest up to 10% of its total assets in preferred securities. In addition, the Fund may invest in both investment-grade securities and high yield securities ("junk bonds") subject to a maximum of 15% its total assets in securities rated below B by Moody's Investors Service, Inc. ("Moody's"), or equivalently rated by Standard & Poor's Ratings Services ("S&P") or Fitch, Inc. ("Fitch"), or, if unrated, determined by PIMCO to be of comparable quality. The average portfolio duration of this Fund varies based on PIMCO's market forecasts and, under normal market conditions, is not expected to exceed eight years. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates.

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, 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.

Emerging Markets Risk: the risk of investing in emerging market securities, primarily increased foreign (non-U.S.) investment risk

Performance Information

The Fund measures its performance against a primary benchmark and a secondary benchmark. Effective September 29, 2017, the Fund's primary benchmark is the Bloomberg Barclays Global Aggregate (USD Unhedged) Index, which provides a broad-based measure of the global investment-grade fixed income markets. The three major components of this index are the U.S. Aggregate, the Pan-European Aggregate, and the Asian-Pacific Aggregate Indices. The index also includes Eurodollar and Euro-Yen corporate bonds, Canadian Government securities, and USD investment grade 144A securities. It is not possible to invest directly in an unmanaged index. Prior to September 29, 2017, the Fund's primary benchmark was the Bloomberg Barclays U.S. Aggregate Index, which represents securities that are SEC-registered, taxable and dollar denominated. The index covers the U.S. investment-grade fixed rate bond market, with index components for government and corporate securities, mortgage pass-through securities, and asset-backed securities. These major sectors are subdivided into more specific indices that are calculated and reported on a regular basis. The Fund believes that the new primary benchmark better aligns with the Fund's investment strategy. The Fund's secondary benchmark index, PIMCO Global Advantage Bond Index® ("GLADI") (USD Partially Hedged), is a diversified global index that covers a wide spectrum of global fixed income opportunities and sectors, from developed to emerging markets, nominal to real asset, and cash to derivative instruments. Unlike traditional indices, which are frequently comprised of bonds weighted according to their market capitalization, GLADI uses GDP weighting which puts an emphasis on faster-growing areas of the world and thus makes the index forward-looking in nature. This contrasts with traditional market capitalization-weighted indices, which emphasize past debt issuance and are therefore backward-looking. GDP weighting also tends to lead to counter-cyclical rebalancing—as bond prices tend to be inversely related to GDP growth rates—and avoids some of the disadvantages of traditional market-cap weighted indices, such as allocating too heavily toward overpriced securities, government debt, and large debt issuers. The Fund believes that the secondary benchmark reflects the Fund's investment strategy more accurately than the Bloomberg Barclays Global Aggregate (USD Unhedged) Index. The Lipper Global Income Funds Average is a total return performance average of funds tracked by Lipper, Inc. that invest primarily in U.S. dollar and non-U.S. dollar debt securities of issuers located in at least three countries, one of which may be the United States.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing under normal circumstances at least 80% of its assets in Fixed Income Instruments that are economically tied to at least three countries (one of which may be the United States), which may be represented by forwards or derivatives such as options, future contracts or swap agreements. "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. Securities may be denominated in major foreign currencies or the U.S. dollar.

PIMCO selects the Fund's foreign country and currency compositions based on an evaluation of various factors, including, but not limited to, relative interest rates, exchange rates, monetary and fiscal policies, trade and current account balances. The Fund may invest, without limitation, in securities and instruments that are economically tied to emerging market countries. The Fund normally invests at least 25% of its net assets in instruments that are economically tied to foreign (non-U.S.) countries. The average portfolio duration of this Fund normally varies between two and eight years. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates. The Fund invests primarily in investment grade securities, but may invest up to 20% of its total assets in high yield securities ("junk bonds"), as rated by Moody's Investors Service, Inc. ("Moody's"), Standard & Poor's Ratings Services ("S&P") or Fitch, Inc. ("Fitch"), or, if unrated, as determined by PIMCO. 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 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, 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 securities.

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 listed below.

Emerging Markets Risk: the risk of investing in emerging market securities, primarily increased foreign (non-U.S.) investment risk

Performance Information

The Fund's broad-based securities market index is the Bloomberg Barclays Global Aggregate (USD Unhedged) Index. The Bloomberg Barclays Global Aggregate (USD Unhedged) Index provides a broad-based measure of the global investment-grade fixed income markets.

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 I-2 shares (April 30, 2008), performance information shown in the table for that class is based on the performance of the Fund's Institutional Class shares, adjusted to reflect the fees and expenses paid by that class of shares. Performance for Class A and Class C shares in the Average Annual Total Returns table reflects the impact of sales charges.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing under normal circumstances at least 80% of its assets in Fixed Income Instruments. The Fund will invest under normal circumstances in Fixed Income Instruments that are economically tied to at least three non-U.S. countries. The Fund's investments in Fixed Income Instruments may be represented by forwards or derivatives such as options, futures contracts or swap agreements. "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.

PIMCO selects the Fund's foreign country and currency compositions based on an evaluation of various factors, including, but not limited to relative interest rates, exchange rates, monetary and fiscal policies, trade and current account balances. The average portfolio duration of this Fund normally varies within three years (plus or minus) of the portfolio duration of the securities comprising the Bloomberg Barclays Global Aggregate ex-USD (USD Unhedged) Index, as calculated by PIMCO, which as of May 31, 2018 was 7.90 years. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates. The Fund invests primarily in investment grade debt securities, but may invest up to 10% of its total assets in high yield securities ("junk bonds"), as rated by Moody's Investors Service, Inc. ("Moody's"), Standard & Poor's Ratings Services ("S&P") or Fitch, Inc. ("Fitch"), or, if unrated, as determined by PIMCO. The Fund may invest, without limitation, in securities and instruments that are economically tied to emerging market countries.

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, 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 securities.

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 listed below.

Emerging Markets Risk: the risk of investing in emerging market securities, primarily increased foreign (non-U.S.) investment risk

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 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 I-2 shares (April 30, 2008), performance information shown in the table for that class is based on the performance of the Fund's Institutional Class shares, adjusted to reflect the fees and expenses paid by I-2 shares. Performance for Class A and Class C shares in the Average Annual Total Returns table reflects the impact of sales charges. Because I-3 shares of the Fund had not commenced operations as of December 31, 2017, no performance for I-3 shares is provided. 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 broad-based securities market index is the Bloomberg Barclays Global Aggregate ex-USD (USD Unhedged) Index. The Bloomberg Barclays Global Aggregate ex-USD (USD Unhedged) Index provides a broad-based measure of the global investment-grade fixed income markets, excluding USD. The two major components of this index are the Pan-European Aggregate and the Asian-Pacific Aggregate Indices. The index also includes Euro-Yen corporate bonds and Canadian Government securities. It is not possible to invest directly in an unmanaged index.

Example. The Example is intended to help you compare the cost of investing in Institutional Class, I-2, I-3, Administrative Class, 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. Investors may pay brokerage commissions on their purchases and sales of Institutional Class, I-2 or I-3 shares of the Fund, which are not reflected in the Example. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Principal Investment Strategies

PIMCO selects the Fund's foreign country and currency compositions based on an evaluation of various factors, including, but not limited to relative interest rates, exchange rates, monetary and fiscal policies, trade and current account balances. The Fund may invest, without limitation, in securities and instruments that are economically tied to emerging market countries. The average portfolio duration of this Fund normally varies within three years (plus or minus) of the portfolio duration of the securities comprising the Bloomberg Barclays Global Aggregate ex-USD (USD Hedged) Index, as calculated by PIMCO, which as of May 31, 2018 was 7.90 years. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates. The Fund invests primarily in investment grade debt securities, but may invest up to 10% of its total assets in high yield securities ("junk bonds"), as rated by Moody's Investors Service, Inc. ("Moody's"), Standard & Poor's Ratings Services ("S&P") or Fitch, Inc. ("Fitch"), or, if unrated, as determined by PIMCO. 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 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, 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 securities.

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 I-2 shares (April 30, 2008), performance information shown in the table for that class is based on the performance of the Fund's Institutional Class shares, adjusted to reflect the fees and expenses paid by I-2 shares. Performance for Class A and Class C shares in the Average Annual Total Returns table reflects the impact of sales charges. Because I-3 shares of the Fund had not commenced operations as of December 31, 2017, no performance for I-3 shares is provided. 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 broad-based securities market index is the Bloomberg Barclays Global Aggregate ex-USD (USD Hedged) Index. The Bloomberg Barclays Global Aggregate ex-USD (USD Hedged) Index provides a broad-based measure of the global investment-grade fixed income markets, excluding USD. The two major components of this index are the Pan-European Aggregate and the Asian-Pacific Aggregate Indices. The index also includes Euro-Yen corporate bonds and Canadian Government securities. It is not possible to invest directly in an unmanaged index. The Lipper International Income Funds Average is a total return performance average of funds tracked by Lipper, Inc. that invest primarily in U.S. dollar and non-U.S. dollar debt securities of issuers located in at least three countries, excluding the United States, except in periods of market weakness.
