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):

Annual Fund Operating Expenses (Institutional) (PIMCO Worldwide Fundamental Advantage TR Strategy Fund)		Institutional Class	Class P	Administrative Class	Class D
Management Fees		0.99%	1.09%	0.99%	1.14%
Distribution and/or Service (12b-1) Fees				0.25%	0.25%
Other Expenses	[1]	0.01%	0.01%	0.01%	0.01%

Fee Waiver and/or Expense Reimbursement	[2]	(0.01%)	(0.01%)	(0.01%)	(0.01%)
Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement		0.99%	1.09%	1.24%	1.39%

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, based on these assumptions your costs would be:

Expense Example (PIMCO Worldwide Fundamental Advantage TR Strategy Fund) (Institutional) (USD $)	1 Year	3 Years
Institutional Class	101	315
Class P	111	347
Administrative Class	126	393
Class D	142	440

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. The Fund has not yet commenced operations as of the most recent fiscal year end. Thus, no portfolio turnover rate is provided for the Fund.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing under normal circumstances in derivatives providing exposure to a proprietary global equity market neutral index designed by the Fund's sub-adviser, Research Affiliates, LLC ("Research Affiliates"), backed by a diversified portfolio of short and intermediate maturity 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's strategy with respect to maintaining exposure to the RAFI® Country Neutral L/S Global Index (the "Index") can be characterized as "market neutral" because it seeks to maintain equal long and short equity positions while returning the relative appreciation (or depreciation) of the Index. The Fund will invest in instruments that are economically tied to at least three countries (one of which may be the United States).

The Index consists of stocks issued by companies domiciled in developed and developing countries that satisfy certain liquidity and other proprietary inclusion criteria. Stocks held long in the Index are weighted by a combination of fundamental factors, including sales, cash flow, book values and, if applicable, dividends (sales, cash flow and dividends are averaged over the prior five years). The Index seeks to capture outperformance relative to stocks held short in the Index, which are weighted by market capitalization. Capitalization weighted indexes generally overweight overvalued stocks and underweight undervalued stocks. By contrast, indexes based on fundamental factors, such as the Index, seek to avoid this problem by weighting stocks based on variables that do not depend on the fluctuations of market valuation. The Index seeks to capture the return difference between a fundamental and capitalization weighted index of stocks. The number of companies selected for inclusion in the Index and related weightings are calibrated using a proprietary algorithm that looks to enhance return, liquidity and diversification. The Index may include, and therefore the Fund may invest in, securities issued by large-capitalization, mid-capitalization and small-capitalization companies.

The Fund may invest in common stocks, options, futures, options on futures and swaps to approximate exposure to the Index or other similar indexes. The Fund typically will seek to simultaneously gain long and short exposure to the Index, each in an amount, under normal circumstances, approximately equal to the Fund's net assets. While the Fund will, under normal circumstances, seek to maintain approximately equal value exposure in its long and short positions in the Index in an effort to offset the effects on the Fund's performance of general stock market movements, PIMCO may increase or decrease the Fund's long or short exposure to the Index when PIMCO deems it appropriate to do so. Because the Index is a proprietary index, there may be a limited number of counterparties willing or able to serve as counterparties to a swap agreement. If such swap agreements are not available, or when PIMCO otherwise deems it appropriate to do so, the Fund may invest in, or take short positions in, other derivative instruments, "baskets" of stocks, or individual securities to replicate the performance of the Index. The Fund also may invest in exchange-traded funds.

The values of derivatives based on the Index should closely track changes in the value of the Index. However, these derivatives may be purchased with a fraction of the assets that would be needed to purchase the equity securities directly, so that the remainder of the Fund's assets may be invested in Fixed Income Instruments. Research Affiliates provides investment advisory services in connection with the Fund's use of the Index by, among other things, providing PIMCO, or counterparties designated by PIMCO, with a model portfolio reflecting the composition of the Index for purposes of developing the Index derivatives. PIMCO actively manages the Fixed Income Instruments held by the Fund with a view toward enhancing the Fund's total return, subject to an overall portfolio duration which normally varies from (negative) 3 years to positive 8 years based on PIMCO's forecast for interest rates. 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 currency options, futures, options on futures and 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. Assets not invested in equity securities or derivatives may be invested in Fixed Income Instruments. The Fund may invest up to 10% of its total assets in high yield securities ("junk bonds") rated B or higher 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 may also invest, without limitation, in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. The Fund may invest up to 15% of its total assets in Fixed Income Instruments that are economically tied to emerging market countries, but may gain emerging markets exposure beyond this limit through other securities and instruments. The Fund will normally limit its foreign currency exposure from non-U.S. dollar-denominated Fixed Income Instruments to 20% of its total assets, but may gain foreign currency exposure beyond this limit through other securities and instruments. 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. Although the Fund seeks to protect against equity market risk arising from its long exposure to the Index by maintaining short exposure to a proprietary index of market capitalization weighted global equities, under certain conditions, generally in a market where the Index underperforms relative to the proprietary index of market capitalization weighted global equities and fixed income securities are declining or in periods of heightened market volatility, the Fund may experience 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 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

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 risk 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. Foreign securities may also be less liquid and more difficult to value than securities of U.S. issuers

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

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

Management Risk: the risk that the investment techniques and risk analyses applied by PIMCO and Research Affiliates will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to PIMCO, Research Affiliates 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

Small-Cap and Mid-Cap Company Risk: the risk that the value of securities issued by small-capitalization and mid-capitalization companies may go up or down, sometimes rapidly and unpredictably, due to narrow markets and limited managerial and financial resources

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.

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. The Fund has not yet commenced operations as of the most recent fiscal year end. Thus, no portfolio turnover rate is provided for the Fund.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing under normal circumstances in derivatives providing exposure to a proprietary global equity market neutral index designed by the Fund's sub-adviser, Research Affiliates, LLC ("Research Affiliates"), backed by a diversified portfolio of short and intermediate maturity 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's strategy with respect to maintaining exposure to the RAFI® Country Neutral L/S Global Index (the "Index") can be characterized as "market neutral" because it seeks to maintain equal long and short equity positions while returning the relative appreciation (or depreciation) of the Index. The Fund will invest in instruments that are economically tied to at least three countries (one of which may be the United States).

The Index consists of stocks issued by companies domiciled in developed and developing countries that satisfy certain liquidity and other proprietary inclusion criteria. Stocks held long in the Index are weighted by a combination of fundamental factors, including sales, cash flow, book values and, if applicable, dividends (sales, cash flow and dividends are averaged over the prior five years). The Index seeks to capture outperformance relative to stocks held short in the Index, which are weighted by market capitalization. Capitalization weighted indexes generally overweight overvalued stocks and underweight undervalued stocks. By contrast, indexes based on fundamental factors, such as the Index, seek to avoid this problem by weighting stocks based on variables that do not depend on the fluctuations of market valuation. The Index seeks to capture the return difference between a fundamental and capitalization weighted index of stocks. The number of companies selected for inclusion in the Index and related weightings are calibrated using a proprietary algorithm that looks to enhance return, liquidity and diversification. The Index may include, and therefore the Fund may invest in, securities issued by large-capitalization, mid-capitalization and small-capitalization companies.

The Fund may invest in common stocks, options, futures, options on futures and swaps to approximate exposure to the Index or other similar indexes. The Fund typically will seek to simultaneously gain long and short exposure to the Index, each in an amount, under normal circumstances, approximately equal to the Fund's net assets. While the Fund will, under normal circumstances, seek to maintain approximately equal value exposure in its long and short positions in the Index in an effort to offset the effects on the Fund's performance of general stock market movements, PIMCO may increase or decrease the Fund's long or short exposure to the Index when PIMCO deems it appropriate to do so. Because the Index is a proprietary index, there may be a limited number of counterparties willing or able to serve as counterparties to a swap agreement. If such swap agreements are not available, or when PIMCO otherwise deems it appropriate to do so, the Fund may invest in, or take short positions in, other derivative instruments, "baskets" of stocks, or individual securities to replicate the performance of the Index. The Fund also may invest in exchange-traded funds.

The values of derivatives based on the Index should closely track changes in the value of the Index. However, these derivatives may be purchased with a fraction of the assets that would be needed to purchase the equity securities directly, so that the remainder of the Fund's assets may be invested in Fixed Income Instruments. Research Affiliates provides investment advisory services in connection with the Fund's use of the Index by, among other things, providing PIMCO, or counterparties designated by PIMCO, with a model portfolio reflecting the composition of the Index for purposes of developing the Index derivatives. PIMCO actively manages the Fixed Income Instruments held by the Fund with a view toward enhancing the Fund's total return, subject to an overall portfolio duration which normally varies from (negative) 3 years to positive 8 years based on PIMCO's forecast for interest rates. 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 currency options, futures, options on futures and 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. Assets not invested in equity securities or derivatives may be invested in Fixed Income Instruments. The Fund may invest up to 10% of its total assets in high yield securities ("junk bonds") rated B or higher 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 may also invest, without limitation, in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. The Fund may invest up to 15% of its total assets in Fixed Income Instruments that are economically tied to emerging market countries, but may gain emerging markets exposure beyond this limit through other securities and instruments. The Fund will normally limit its foreign currency exposure from non-U.S. dollar-denominated Fixed Income Instruments to 20% of its total assets, but may gain foreign currency exposure beyond this limit through other securities and instruments. 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. Although the Fund seeks to protect against equity market risk arising from its long exposure to the Index by maintaining short exposure to a proprietary index of market capitalization weighted global equities, under certain conditions, generally in a market where the Index underperforms relative to the proprietary index of market capitalization weighted global equities and fixed income securities are declining or in periods of heightened market volatility, the Fund may experience 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 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

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 risk 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. Foreign securities may also be less liquid and more difficult to value than securities of U.S. issuers

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

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

Management Risk: the risk that the investment techniques and risk analyses applied by PIMCO and Research Affiliates will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to PIMCO, Research Affiliates 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

Small-Cap and Mid-Cap Company Risk: the risk that the value of securities issued by small-capitalization and mid-capitalization companies may go up or down, sometimes rapidly and unpredictably, due to narrow markets and limited managerial and financial resources

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.

[2] PIMCO has contractually agreed, through July 31, 2014, to waive its supervisory and administrative fee, or reimburse the Fund, to the extent that organizational expenses and pro rata Trustees' fees exceed 0.0049% of the Fund's average net assets attributable to Class A, Class C and Class R shares, respectively (the "Expense Limit"). Under the Expense Limitation Agreement, which renews annually for a full year unless terminated by PIMCO upon at least 30 days' notice prior to the end of the contract term, PIMCO may recoup these waivers and reimbursements in future periods, not exceeding three years, provided organizational expenses and pro rata Trustees' fees plus such recoupment, do not exceed the Expense Limit.

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):

Annual Fund Operating Expenses (Institutional) (PIMCO Worldwide Fundamental Advantage TR Strategy Fund)		Institutional Class	Class P	Administrative Class	Class D
Management Fees		0.99%	1.09%	0.99%	1.14%
Distribution and/or Service (12b-1) Fees				0.25%	0.25%
Other Expenses	[1]	0.01%	0.01%	0.01%	0.01%
Total Annual Fund Operating Expenses		1.00%	1.10%	1.25%	1.40%
Fee Waiver and/or Expense Reimbursement	[2]	(0.01%)	(0.01%)	(0.01%)	(0.01%)
Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement		0.99%	1.09%	1.24%	1.39%

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, based on these assumptions your costs would be:

Expense Example (PIMCO Worldwide Fundamental Advantage TR Strategy Fund) (Institutional) (USD $)	1 Year	3 Years
Institutional Class	101	315
Class P	111	347
Administrative Class	126	393
Class D	142	440

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. The Fund has not yet commenced operations as of the most recent fiscal year end. Thus, no portfolio turnover rate is provided for the Fund.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing under normal circumstances in derivatives providing exposure to a proprietary global equity market neutral index designed by the Fund's sub-adviser, Research Affiliates, LLC ("Research Affiliates"), backed by a diversified portfolio of short and intermediate maturity 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's strategy with respect to maintaining exposure to the RAFI® Country Neutral L/S Global Index (the "Index") can be characterized as "market neutral" because it seeks to maintain equal long and short equity positions while returning the relative appreciation (or depreciation) of the Index. The Fund will invest in instruments that are economically tied to at least three countries (one of which may be the United States).

The Index consists of stocks issued by companies domiciled in developed and developing countries that satisfy certain liquidity and other proprietary inclusion criteria. Stocks held long in the Index are weighted by a combination of fundamental factors, including sales, cash flow, book values and, if applicable, dividends (sales, cash flow and dividends are averaged over the prior five years). The Index seeks to capture outperformance relative to stocks held short in the Index, which are weighted by market capitalization. Capitalization weighted indexes generally overweight overvalued stocks and underweight undervalued stocks. By contrast, indexes based on fundamental factors, such as the Index, seek to avoid this problem by weighting stocks based on variables that do not depend on the fluctuations of market valuation. The Index seeks to capture the return difference between a fundamental and capitalization weighted index of stocks. The number of companies selected for inclusion in the Index and related weightings are calibrated using a proprietary algorithm that looks to enhance return, liquidity and diversification. The Index may include, and therefore the Fund may invest in, securities issued by large-capitalization, mid-capitalization and small-capitalization companies.

The Fund may invest in common stocks, options, futures, options on futures and swaps to approximate exposure to the Index or other similar indexes. The Fund typically will seek to simultaneously gain long and short exposure to the Index, each in an amount, under normal circumstances, approximately equal to the Fund's net assets. While the Fund will, under normal circumstances, seek to maintain approximately equal value exposure in its long and short positions in the Index in an effort to offset the effects on the Fund's performance of general stock market movements, PIMCO may increase or decrease the Fund's long or short exposure to the Index when PIMCO deems it appropriate to do so. Because the Index is a proprietary index, there may be a limited number of counterparties willing or able to serve as counterparties to a swap agreement. If such swap agreements are not available, or when PIMCO otherwise deems it appropriate to do so, the Fund may invest in, or take short positions in, other derivative instruments, "baskets" of stocks, or individual securities to replicate the performance of the Index. The Fund also may invest in exchange-traded funds.

The values of derivatives based on the Index should closely track changes in the value of the Index. However, these derivatives may be purchased with a fraction of the assets that would be needed to purchase the equity securities directly, so that the remainder of the Fund's assets may be invested in Fixed Income Instruments. Research Affiliates provides investment advisory services in connection with the Fund's use of the Index by, among other things, providing PIMCO, or counterparties designated by PIMCO, with a model portfolio reflecting the composition of the Index for purposes of developing the Index derivatives. PIMCO actively manages the Fixed Income Instruments held by the Fund with a view toward enhancing the Fund's total return, subject to an overall portfolio duration which normally varies from (negative) 3 years to positive 8 years based on PIMCO's forecast for interest rates. 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 currency options, futures, options on futures and 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. Assets not invested in equity securities or derivatives may be invested in Fixed Income Instruments. The Fund may invest up to 10% of its total assets in high yield securities ("junk bonds") rated B or higher 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 may also invest, without limitation, in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. The Fund may invest up to 15% of its total assets in Fixed Income Instruments that are economically tied to emerging market countries, but may gain emerging markets exposure beyond this limit through other securities and instruments. The Fund will normally limit its foreign currency exposure from non-U.S. dollar-denominated Fixed Income Instruments to 20% of its total assets, but may gain foreign currency exposure beyond this limit through other securities and instruments. 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. Although the Fund seeks to protect against equity market risk arising from its long exposure to the Index by maintaining short exposure to a proprietary index of market capitalization weighted global equities, under certain conditions, generally in a market where the Index underperforms relative to the proprietary index of market capitalization weighted global equities and fixed income securities are declining or in periods of heightened market volatility, the Fund may experience 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 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

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 risk 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. Foreign securities may also be less liquid and more difficult to value than securities of U.S. issuers

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

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

Management Risk: the risk that the investment techniques and risk analyses applied by PIMCO and Research Affiliates will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to PIMCO, Research Affiliates 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

Small-Cap and Mid-Cap Company Risk: the risk that the value of securities issued by small-capitalization and mid-capitalization companies may go up or down, sometimes rapidly and unpredictably, due to narrow markets and limited managerial and financial resources

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.

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. The Fund has not yet commenced operations as of the most recent fiscal year end. Thus, no portfolio turnover rate is provided for the Fund.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing under normal circumstances in derivatives providing exposure to a proprietary global equity market neutral index designed by the Fund's sub-adviser, Research Affiliates, LLC ("Research Affiliates"), backed by a diversified portfolio of short and intermediate maturity 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.

By contrast, indexes based on fundamental factors, such as the Index, seek to avoid this problem by weighting stocks based on variables that do not depend on the fluctuations of market valuation. The Index seeks to capture the return difference between a fundamental and capitalization weighted index of stocks. The number of companies selected for inclusion in the Index and related weightings are calibrated using a proprietary algorithm that looks to enhance return, liquidity and diversification. The Index may include, and therefore the Fund may invest in, securities issued by large-capitalization, mid-capitalization and small-capitalization companies.

The Fund may invest in common stocks, options, futures, options on futures and swaps to approximate exposure to the Index or other similar indexes. The Fund typically will seek to simultaneously gain long and short exposure to the Index, each in an amount, under normal circumstances, approximately equal to the Fund's net assets. While the Fund will, under normal circumstances, seek to maintain approximately equal value exposure in its long and short positions in the Index in an effort to offset the effects on the Fund's performance of general stock market movements, PIMCO may increase or decrease the Fund's long or short exposure to the Index when PIMCO deems it appropriate to do so. Because the Index is a proprietary index, there may be a limited number of counterparties willing or able to serve as counterparties to a swap agreement. If such swap agreements are not available, or when PIMCO otherwise deems it appropriate to do so, the Fund may invest in, or take short positions in, other derivative instruments, "baskets" of stocks, or individual securities to replicate the performance of the Index. The Fund also may invest in exchange-traded funds.

The values of derivatives based on the Index should closely track changes in the value of the Index. However, these derivatives may be purchased with a fraction of the assets that would be needed to purchase the equity securities directly, so that the remainder of the Fund's assets may be invested in Fixed Income Instruments.

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 currency options, futures, options on futures and 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. Assets not invested in equity securities or derivatives may be invested in Fixed Income Instruments. The Fund may invest up to 10% of its total assets in high yield securities ("junk bonds") rated B or higher 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 may also invest, without limitation, in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. The Fund may invest up to 15% of its total assets in Fixed Income Instruments that are economically tied to emerging market countries, but may gain emerging markets exposure beyond this limit through other securities and instruments. The Fund will normally limit its foreign currency exposure from non-U.S. dollar-denominated Fixed Income Instruments to 20% of its total assets, but may gain foreign currency exposure beyond this limit through other securities and instruments. 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. Although the Fund seeks to protect against equity market risk arising from its long exposure to the Index by maintaining short exposure to a proprietary index of market capitalization weighted global equities, under certain conditions, generally in a market where the Index underperforms relative to the proprietary index of market capitalization weighted global equities and fixed income securities are declining or in periods of heightened market volatility, the Fund may experience 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 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

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 risk 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. Foreign securities may also be less liquid and more difficult to value than securities of U.S. issuers

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

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

Management Risk: the risk that the investment techniques and risk analyses applied by PIMCO and Research Affiliates will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to PIMCO, Research Affiliates 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

Small-Cap and Mid-Cap Company Risk: the risk that the value of securities issued by small-capitalization and mid-capitalization companies may go up or down, sometimes rapidly and unpredictably, due to narrow markets and limited managerial and financial resources

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.

The Fund seeks to achieve its investment objective by investing under normal circumstances in derivatives providing exposure to a proprietary global equity market neutral index designed by the Fund's sub-adviser, Research Affiliates, LLC ("Research Affiliates"), backed by a diversified portfolio of short and intermediate maturity 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's strategy with respect to maintaining exposure to the RAFI® Country Neutral L/S Global Index (the "Index") can be characterized as "market neutral" because it seeks to maintain equal long and short equity positions while returning the relative appreciation (or depreciation) of the Index. The Fund will invest in instruments that are economically tied to at least three countries (one of which may be the United States).

The Index consists of stocks issued by companies domiciled in developed and developing countries that satisfy certain liquidity and other proprietary inclusion criteria. Stocks held long in the Index are weighted by a combination of fundamental factors, including sales, cash flow, book values and, if applicable, dividends (sales, cash flow and dividends are averaged over the prior five years). The Index seeks to capture outperformance relative to stocks held short in the Index, which are weighted by market capitalization. Capitalization weighted indexes generally overweight overvalued stocks and underweight undervalued stocks. By contrast, indexes based on fundamental factors, such as the Index, seek to avoid this problem by weighting stocks based on variables that do not depend on the fluctuations of market valuation. The Index seeks to capture the return difference between a fundamental and capitalization weighted index of stocks. The number of companies selected for inclusion in the Index and related weightings are calibrated using a proprietary algorithm that looks to enhance return, liquidity and diversification. The Index may include, and therefore the Fund may invest in, securities issued by large-capitalization, mid-capitalization and small-capitalization companies.

The Fund may invest in common stocks, options, futures, options on futures and swaps to approximate exposure to the Index or other similar indexes. The Fund typically will seek to simultaneously gain long and short exposure to the Index, each in an amount, under normal circumstances, approximately equal to the Fund's net assets. While the Fund will, under normal circumstances, seek to maintain approximately equal value exposure in its long and short positions in the Index in an effort to offset the effects on the Fund's performance of general stock market movements, PIMCO may increase or decrease the Fund's long or short exposure to the Index when PIMCO deems it appropriate to do so. Because the Index is a proprietary index, there may be a limited number of counterparties willing or able to serve as counterparties to a swap agreement. If such swap agreements are not available, or when PIMCO otherwise deems it appropriate to do so, the Fund may invest in, or take short positions in, other derivative instruments, "baskets" of stocks, or individual securities to replicate the performance of the Index. The Fund also may invest in exchange-traded funds.

The values of derivatives based on the Index should closely track changes in the value of the Index. However, these derivatives may be purchased with a fraction of the assets that would be needed to purchase the equity securities directly, so that the remainder of the Fund's assets may be invested in Fixed Income Instruments. Research Affiliates provides investment advisory services in connection with the Fund's use of the Index by, among other things, providing PIMCO, or counterparties designated by PIMCO, with a model portfolio reflecting the composition of the Index for purposes of developing the Index derivatives. PIMCO actively manages the Fixed Income Instruments held by the Fund with a view toward enhancing the Fund's total return, subject to an overall portfolio duration which normally varies from (negative) 3 years to positive 8 years based on PIMCO's forecast for interest rates. 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 currency options, futures, options on futures and 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. Assets not invested in equity securities or derivatives may be invested in Fixed Income Instruments. The Fund may invest up to 10% of its total assets in high yield securities ("junk bonds") rated B or higher 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 may also invest, without limitation, in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. The Fund may invest up to 15% of its total assets in Fixed Income Instruments that are economically tied to emerging market countries, but may gain emerging markets exposure beyond this limit through other securities and instruments. The Fund will normally limit its foreign currency exposure from non-U.S. dollar-denominated Fixed Income Instruments to 20% of its total assets, but may gain foreign currency exposure beyond this limit through other securities and instruments. The Fund may also invest up to 10% of its total assets in preferred stocks.

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

It is possible to lose money on an investment in the Fund. Although the Fund seeks to protect against equity market risk arising from its long exposure to the Index by maintaining short exposure to a proprietary index of market capitalization weighted global equities, under certain conditions, generally in a market where the Index underperforms relative to the proprietary index of market capitalization weighted global equities and fixed income securities are declining or in periods of heightened market volatility, the Fund may experience 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 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

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 risk 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. Foreign securities may also be less liquid and more difficult to value than securities of U.S. issuers

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

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

Management Risk: the risk that the investment techniques and risk analyses applied by PIMCO and Research Affiliates will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to PIMCO, Research Affiliates 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

Small-Cap and Mid-Cap Company Risk: the risk that the value of securities issued by small-capitalization and mid-capitalization companies may go up or down, sometimes rapidly and unpredictably, due to narrow markets and limited managerial and financial resources

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.

It is possible to lose money on an investment in the Fund. Although the Fund seeks to protect against equity market risk arising from its long exposure to the Index by maintaining short exposure to a proprietary index of market capitalization weighted global equities, under certain conditions, generally in a market where the Index underperforms relative to the proprietary index of market capitalization weighted global equities and fixed income securities are declining or in periods of heightened market volatility, the Fund may experience 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 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

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 risk 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. Foreign securities may also be less liquid and more difficult to value than securities of U.S. issuers

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

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

Management Risk: the risk that the investment techniques and risk analyses applied by PIMCO and Research Affiliates will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to PIMCO, Research Affiliates 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

Small-Cap and Mid-Cap Company Risk: the risk that the value of securities issued by small-capitalization and mid-capitalization companies may go up or down, sometimes rapidly and unpredictably, due to narrow markets and limited managerial and financial resources

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
