First Eagle Global Fund

First Eagle Global Fund

Investment Objective

First Eagle Global Fund (“Global Fund”) seeks long-term growth of capital by investing in a range of asset classes from markets in the United States and throughout the world.

Fees and Expenses of the Global Fund

The following information describes the fees and expenses you may pay if you buy and hold shares of the Global Fund.

You may qualify for sales charge discounts if you invest at least $250,000 in the Global Fund. Information about these discounts is available from your financial professional and in the How to Purchase Shares and Public Offering Price of Class T Shares sections on pages 65 and 71, respectively, and in the appendix to this Prospectus titled Intermediary-Specific Sales Load and Waiver Terms.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	First Eagle Global Fund Class T
Maximum Sales Charge (Load) on Purchases (as a percentage of public offering price)	2.50%
Maximum Deferred Sales Charge (Load) (as a percentage of the lesser of your purchase or redemption price)	none

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

Annual Fund Operating Expenses	First Eagle Global Fund Class T
Management Fees	0.75%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.10%	[1]
Total Annual Operating Expenses (%)	1.10%

Example

The following example is intended to help you compare the cost of investing in the Global Fund with the cost of investing in other mutual funds. This hypothetical example assumes you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem all shares at the end of those periods. The example also assumes the average annual return is 5% and operating expenses remain the same. Please keep in mind your actual costs may be higher or lower.

Sold

Expense Example	1 Year	3 Years	5 Years	10 Years
First Eagle Global Fund | Class T | USD ($)	359	591	841	1,557

Held

Expense Example No Redemption	1 Year	3 Years	5 Years	10 Years
First Eagle Global Fund | Class T | USD ($)	359	591	841	1,557

Portfolio Turnover Rate

The Global Fund pays transaction costs, such as commissions, 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 the Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 11.54% of the average value of its portfolio.

Principal Investment Strategies

To achieve its objective of long-term capital growth, the Global Fund will normally invest primarily in common stocks (and securities convertible into common stocks) of U.S. and foreign companies.

Investment decisions for the Fund are made without regard to the capitalization (size) of the companies in which it invests. The Fund may invest in any size company, including large, medium and smaller companies. The Fund may also invest in fixed-income instruments (without regard to credit rating or time to maturity), short-term debt instruments, gold and other precious metals, and futures contracts related to precious metals. Under normal circumstances, the Fund anticipates it will allocate a substantial amount of its assets to foreign investments. That generally means that approximately 40% or more of the Fund’s net assets (plus any borrowings for investment purposes) will be allocated to foreign investments (unless market conditions are not deemed favorable by the Fund, in which case the Fund expects to invest at least 30% of its net assets (plus any borrowings for investment purposes) in foreign investments). For purposes of these 40% and 30% of assets allocations, the Fund “counts” relevant derivative positions on foreign investments, and in doing so, values each position at the price at which it is held on the Fund’s books.

The investment philosophy and strategy of the Global Fund can be broadly characterized as a “value” approach, as it seeks a “margin of safety” in each investment purchase with the goal being to avoid permanent impairment of capital (as opposed to temporary losses in share value relating to shifting investor sentiment or other normal share price volatility). In particular, a discount to “intrinsic value” is sought even for the best of businesses, with a deeper discount demanded for companies that we view as under business model, balance sheet, management or other stresses. “Intrinsic value” is based on our judgment of what a prudent and rational business buyer would pay in cash for all of the company in normal markets. See also Defensive Investment Strategies.

The Fund makes some investments through a special purpose trading subsidiary (the “Subsidiary”) and may invest up to 25% of its total assets in the Subsidiary. The Subsidiary is a wholly-owned and controlled subsidiary of the Fund, organized under the laws of the Cayman Islands as an exempted company. Generally, the Subsidiary will invest in commodities and related instruments (primarily gold bullion and other precious metals and related contracts).

Principal Investment Risks

As with any mutual fund investment, you may lose money by investing in the Global Fund. The likelihood of loss may be greater if you invest for a shorter period of time. An investment in the Fund is not intended to be a complete investment program.

Principal Risks of investing in the Global Fund, which could adversely affect its net asset value and total return, are:

•	Market Risk — The value of the Fund’s portfolio holdings may fluctuate in response to events specific to the companies or markets in which the Fund invests, as well as economic, political, or social events in the United States or abroad.
•	Foreign Investment Risk — The Fund may invest in foreign investments. Foreign investments are susceptible to less politically, economically and socially stable environments, foreign currency and exchange rate changes, and adverse changes to government regulations.
•	Small and Medium-Size Company Risk — The Fund may invest in small and medium-size companies, the securities of which can be more volatile in price than those of larger companies. Positions in smaller companies, especially when the Fund is a large holder of a small company’s securities, also may be more difficult or expensive to trade.
•	Gold Risk — The Fund may invest in both physical gold and the securities of companies in the gold mining sector. Prices of gold-related issues are susceptible to changes in U.S. and foreign regulatory policies, taxes, currencies, mining laws, inflation, and various other market conditions.
•	Credit and Interest Rate Risk — The value of the Fund’s portfolio may fluctuate in response to the risk that the issuer of a bond or other instrument will not be able to make payments of interest and principal when due.
	The Fund may invest in debt instruments that are below investment grade, e.g., junk bonds, which are considered speculative, and carry a higher risk of default. In addition, fluctuations in interest rates can affect the value of debt instruments held by the Fund. An increase in interest rates tends to reduce the market value of debt instruments, while a decline in interest rates tends to increase their values. Longer-duration instruments tend to be more sensitive to interest rate changes than those with shorter durations.
•	Derivatives Risk — Futures contracts or other “derivatives,” including hedging strategies, present risks related to their significant price volatility and risk of default by the counterparty to the contract. To date, derivatives have been used mainly under a hedging program intended to reduce the impact of foreign exchange rate changes on the Fund’s value.
•	Currency Risk — Currency risk is the risk that foreign currencies will decline in value relative to that of the U.S. dollar and affect the Fund’s non-U.S. currencies or securities that trade in and receive revenue in non-U.S. currencies.
•	Subsidiary Risk — By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The Subsidiary is not registered under the Investment Company Act of 1940, as amended (the “1940 Act”) and is not subject to all of the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as expected and could adversely affect the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

For more information on the risks of investing in the Global Fund, please see the More Information about the Funds’ Investments section.

Investment Results

The following information provides an indication of the risks of investing in the Global Fund by showing changes in the Fund’s performance from year to year, and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of a broad measure of market performance. As with all mutual funds, past performance is not an indication of future performance (before or after taxes).

After-tax returns are calculated using the highest individual federal income tax rate for each year, and do not reflect the effect of state and local taxes. Actual after-tax returns depend on your individual tax situation. After-tax returns are not relevant to investors in tax-deferred accounts, such as 401(k) plans or individual retirement accounts.

Updated performance information is available at www.feim.com/individual-investors/fund/global-fund or by calling 800.334.2143.

The following bar chart assumes reinvestment of dividends and distributions and does not reflect any sales charges. If sales charges were included the returns would be lower.

Calendar Year Total Returns

Best Quarter*		Worst Quarter*
Third Quarter 2009	14.58%	Fourth Quarter 2008	-10.66%

First quarter 2017 performance was 5.42%.

Average Annual Total Returns as of December 31, 2016

The bar chart above and table below disclose returns only for Class A shares (which are not offered by this prospectus).

While no information is shown for the Class T shares (because they are newly organized), annual returns for Class T shares would have been substantially similar to those shown here. Class T shares are invested in the same portfolio of securities and the annual returns would differ only to the extent that Class T shares do not have the same expenses.

Average Annual Returns - First Eagle Global Fund	1 Year	5 Years	10 Years
Class A	5.12%	6.84%	5.71%
After Taxes on Distributions | Class A	3.99%	5.91%	4.88%
After Taxes on Distributions and Sale of Fund Shares | Class A	3.83%	5.32%	4.56%
MSCI World Index	7.51%	10.41%	3.83%

[1] "Other Expenses" shown generally reflect actual expenses for the Fund for the fiscal year ended October 31, 2016 as adjusted for estimates in the case of newly organized share classes.

First Eagle Overseas Fund

First Eagle Overseas Fund

Investment Objective

First Eagle Overseas Fund (“Overseas Fund”) seeks long-term growth of capital by investing primarily in equities issued by non-U.S. corporations.

Fees and Expenses of the Overseas Fund

The following information describes the fees and expenses you may pay if you buy and hold shares of the Overseas Fund.

Subject to certain exceptions, the Overseas Fund is currently closed to new investors and new accounts. You may find the exceptions in the About Your Investment—Overseas Fund All Share Classes (closed to new investors) section on page 72 of this Prospectus. If you are eligible to purchase shares, you may qualify for sales charge discounts if you invest at least $250,000 in the Overseas Fund. Information about these discounts is available from your financial professional and in the How to Purchase Shares and Public Offering Price of Class T Shares sections on pages 65 and 71, respectively, and in the appendix to this Prospectus titled Intermediary-Specific Sales Load and Waiver Terms.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	First Eagle Overseas Fund Class T
Maximum Sales Charge (Load) on Purchases (as a percentage of public offering price)	2.50%
Maximum Deferred Sales Charge (Load) (as a percentage of the lesser of your purchase or redemption price)	none

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

Example

The following example is intended to help you compare the cost of investing in the Overseas Fund with the cost of investing in other mutual funds. This hypothetical example assumes you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem all shares at the end of those periods. The example also assumes the average annual return is 5% and operating expenses remain the same. Please keep in mind your actual costs may be higher or lower.

Held

Expense Example No Redemption	1 Year	3 Years	5 Years	10 Years
First Eagle Overseas Fund | Class T | USD ($)	363	603	862	1,601

Portfolio Turnover Rate

The Overseas Fund pays transaction costs, such as commissions, 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 annual Fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 9.30% of the average value of its portfolio.

Principal Investment Strategies

To achieve its objective of long-term capital growth, the Overseas Fund will invest primarily in equity securities of companies traded in mature markets (for example, Japan, Germany and France) and may invest in countries whose economies are still developing (sometimes called “emerging markets”). The Fund particularly seeks companies that have financial strength and stability, strong management and fundamental value. Normally, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in foreign securities (and “counts” relevant derivative positions towards this “80% of assets” allocation, and in doing so, values each position at the price at which it is held on the Fund’s books). The Fund also may invest up to 20% of its total assets in debt instruments. The Fund may invest in debt securities generally without regard to their credit rating or time to maturity. Investment decisions for the Fund are made without regard to the capitalization (size) of the companies in which it invests. The Fund may invest in any size company, including large, medium and smaller companies. The Fund may invest in fixed-income instruments, short-term debt instruments, gold and other precious metals, and futures contracts related to precious metals.

The investment philosophy and strategy of the Overseas Fund can be broadly characterized as a “value” approach, as it seeks a “margin of safety” in each investment purchase with the goal being to avoid permanent impairment of capital (as opposed to temporary losses in share value relating to shifting investor sentiment or other normal share price volatility). In particular, a discount to “intrinsic value” is sought even for the best of businesses, with a deeper discount demanded for companies that we view as under business model, balance sheet, management or other stresses. “Intrinsic value” is based on our judgment of what a prudent and rational business buyer would pay in cash for all of the company in normal markets. See also Defensive Investment Strategies.

The Fund makes some investments through a special purpose trading subsidiary (the “Subsidiary”) and may invest up to 25% of its total assets in the Subsidiary. The Subsidiary is a wholly-owned and controlled subsidiary of the Fund, organized under the laws of the Cayman Islands as an exempted company. Generally, the Subsidiary will invest in commodities and related instruments (primarily gold bullion and other precious metals and related contracts).

Principal Investment Risks

As with any mutual fund investment, you may lose money by investing in the Overseas Fund. The likelihood of loss may be greater if you invest for a shorter period of time. An investment in the Fund is not intended to be a complete investment program.

The principal risks of investing in the Overseas Fund, which could adversely affect its net asset value and total return, are:

• Market Risk — The value of the Fund’s portfolio holdings may fluctuate in response to events specific to the companies or markets in which the Fund invests, as well as economic, political, or social events in the United States or abroad.

• Foreign Investment Risk — The Fund may invest in foreign investments. Foreign investments are susceptible to less politically, economically and socially stable environments, foreign currency and exchange rate changes, and adverse changes to government regulations. These risks may be more pronounced with respect to investments in emerging markets.

• Small and Medium-Size Company Risk — The Fund may invest in small and medium-size companies, the securities of which can be more volatile in price than those of larger companies. Positions in smaller companies, especially when the Fund is a large holder of a small company’s securities, also may be more difficult or expensive to trade.

• Credit and Interest Rate Risk — The value of the Fund’s portfolio may fluctuate in response to the risk that the issuer of a bond or other instrument will not be able to make payments of interest and principal when due. The Fund may invest in debt instruments that are below investment grade, e.g., junk bonds, which are considered speculative, and carry a higher risk of default. In addition, fluctuations in interest rates can affect the value of debt instruments held by the Fund. An increase in interest rates tends to reduce the market value of debt instruments, while a decline in interest rates tends to increase their values. Longer-duration instruments tend to be more sensitive to interest rate changes than those with shorter durations.

• Gold Risk — The Fund may invest in both physical gold and the securities of companies in the gold mining sector. Prices of gold-related issues are susceptible to changes in U.S. and foreign regulatory policies, taxes, currencies, mining laws, inflation, and various other market conditions.

• Derivatives Risk — Futures contracts or other “derivatives,” including hedging strategies, present risks related to their significant price volatility and risk of default by the counterparty to the contract. To date, derivatives have been used mainly under a hedging program intended to reduce the impact of foreign exchange rate changes on the Fund’s value.

• Currency Risk — Currency risk is the risk that foreign currencies will decline in value relative to that of the U.S. dollar and affect the Fund’s non-U.S. currencies or securities that trade in and receive revenue in non-U.S. currencies.

• Subsidiary Risk — By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The Subsidiary is not registered under the 1940 Act and is not subject to all of the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as expected and could adversely affect the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

For more information on the risks of investing in the Overseas Fund, please see the More Information about the Funds’ Investments section.

Investment Results

The following information provides an indication of the risks of investing in the Overseas Fund by showing changes in the Fund’s performance from year to year, and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of a broad measure of market performance. As with all mutual funds, past performance is not an indication of future performance (before or after taxes).

After-tax returns are calculated using the highest individual federal income tax rate for each year, and do not reflect the effect of state and local taxes. Actual after-tax returns depend on your individual tax situation. After-tax returns are not relevant to investors in tax-deferred accounts, such as 401(k) plans or individual retirement accounts.

Updated performance information is available at www.feim.com/individual-investors/fund/overseas-fund or by calling 800.334.2143.

The following bar chart assumes reinvestment of dividends and distributions and does not reflect any sales charges. If sales charges were included, the returns would be lower.

Example

The following example is intended to help you compare the cost of investing in the U.S. Value Fund with the cost of investing in other mutual funds. This hypothetical example assumes you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem all shares at the end of those periods. The example also assumes the average annual return is 5% and operating expenses remain the same. Please keep in mind your actual costs may be higher or lower.

Portfolio Turnover Rate

The U.S. Value Fund pays transaction costs, such as commissions, 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 annual Fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 10.65% of the average value of its portfolio.

Principal Investment Strategies

To achieve its objective of long-term capital growth, the U.S. Value Fund will normally invest at least 80% of its net assets (plus any borrowings for investment purposes) in domestic equity and debt instruments and may invest to a lesser extent in securities of non-U.S. issuers. In particular, the Fund seeks companies exhibiting financial strength and stability, strong management and fundamental value. Investment decisions for the Fund are made without regard to the capitalization (size) of the companies in which it invests. The Fund may invest in any size company, including large, medium and smaller companies. The debt instruments in which the Fund may invest include fixed-income securities without regard to credit rating or time to maturity and short-term debt instruments. The Fund may also invest in gold and other precious metals, and futures contracts related to precious metals. The Fund “counts” relevant derivative positions towards its “80% of assets” allocation, and in doing so, values each position at the price at which it is held on the Fund’s books.

The investment philosophy and strategy of the U.S. Value Fund can be broadly characterized as a “value” approach, as it seeks a “margin of safety” in each investment purchase with the goal being to avoid permanent impairment of capital (as opposed to temporary losses in share value relating to shifting investor sentiment or other normal share price volatility). In particular, a discount to “intrinsic value” is sought even for the best of businesses, with a deeper discount demanded for companies that we view as under business model, balance sheet, management or other stresses. “Intrinsic value” is based on our judgment of what a prudent and rational business buyer would pay in cash for all of the company in normal markets. See also Defensive Investment Strategies.

The Fund makes some investments through a special purpose trading subsidiary (the “Subsidiary”) and may invest up to 25% of its total assets in the Subsidiary. The Subsidiary is a wholly-owned and controlled subsidiary of the Fund, organized under the laws of the Cayman Islands as an exempted company. Generally, the Subsidiary will invest in commodities and related instruments (primarily gold bullion and other precious metals and related contracts).

Principal Investment Risks

As with any mutual fund investment, you may lose money by investing in the U.S. Value Fund. The likelihood of loss may be greater if you invest for a shorter period of time. An investment in the Fund is not intended to be a complete investment program.

Principal risks of investing in the U.S. Value Fund, which could adversely affect its net asset value and total return, are:

• Market Risk — The value of the Fund’s portfolio holdings may fluctuate in response to events specific to the companies or markets in which the Fund invests, as well as economic, political, or social events in the United States or abroad.

• Credit and Interest Rate Risk — The value of the Fund’s portfolio may fluctuate in response to the risk that the issuer of a bond or other instrument will not be able to make payments of interest and principal when due. The Fund may invest in debt instruments that are below investment grade, e.g., junk bonds, which are considered speculative, and carry a higher risk of default. In addition, fluctuations in interest rates can affect the value of debt instruments held by the Fund. An increase in interest rates tends to reduce the market value of debt instruments, while a decline in interest rates tends to increase their values. Longer-duration instruments tend to be more sensitive to interest rate changes than those with shorter durations.

• Small and Medium-Size Company Risk — The Fund may invest in small and medium-size companies, the securities of which can be more volatile in price than those of larger companies. Positions in smaller companies, especially when the Fund is a large holder of a small company’s securities, also may be more difficult or expensive to trade.

• Gold Risk — The Fund may invest in both physical gold and the securities of companies in the gold mining sector. Prices of gold-related issues are susceptible to changes in U.S. and foreign regulatory policies, taxes, currencies, mining laws, inflation, and various other market conditions.

• Foreign Investment Risk — The Fund may invest in foreign investments. Foreign investments are susceptible to less politically, economically and socially stable environments, foreign currency and exchange rate changes, and adverse changes to government regulations.

• Illiquid Investment Risk — Holding illiquid securities restricts or otherwise limits the ability for the Fund to freely dispose of its investments for specific periods of time. The Fund might not be able to sell illiquid securities at its desired price or time. Changes in the markets or in regulations governing the trading of illiquid instruments can cause rapid changes in the price or ability to sell an illiquid security.

• Subsidiary Risk — By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The Subsidiary is not registered under the 1940 Act and is not subject to all of the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as expected and could adversely affect the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

For more information on the risks of investing in the U.S. Value Fund, please see the More Information about the Funds’ Investments section.

Investment Results

The following information provides an indication of the risks of investing in the U.S. Value Fund by showing changes in the Fund’s performance from year to year, and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of a broad measure of market performance. As with all mutual funds, past performance is not an indication of future performance (before or after taxes).

After-tax returns are calculated using the highest individual federal income tax rate for each year, and do not reflect the effect of state and local taxes. Actual after-tax returns depend on your individual tax situation. After-tax returns are not relevant to investors in tax-deferred accounts, such as 401(k) plans or individual retirement accounts.

Updated performance information is available at www.feim.com/individual-investors/fund/us-value-fund or by calling 800.334.2143.

The following bar chart assumes reinvestment of dividends and distributions and does not reflect any sales charges. If sales charges were included, the returns would be lower.

First Eagle Gold Fund

First Eagle Gold Fund

Investment Objective

First Eagle Gold Fund (“Gold Fund”) seeks to provide investors the opportunity to participate in the investment characteristics of gold (and to a limited extent other precious metals) for a portion of their overall investment portfolio.

Fees and Expenses of the Gold Fund

The following information describes the fees and expenses you may pay if you buy and hold shares of the Gold Fund.

You may qualify for sales charge discounts if you invest at least $250,000 in the Gold Fund. Information about these discounts is available from your financial professional and in the How to Purchase Shares and Public Offering Price of Class T Shares sections on pages 65 and 71, respectively, and in the appendix to this Prospectus titled Intermediary-Specific Sales Load and Waiver Terms.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	First Eagle Gold Fund Class T
Maximum Sales Charge (Load) on Purchases (as a percentage of public offering price)	2.50%
Maximum Deferred Sales Charge (Load) (as a percentage of the lesser of your purchase or redemption price)	none
Redemption Fee (as a percentage of the amount redeemed within 60 days of purchase)	2.00%

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

Annual Fund Operating Expenses	First Eagle Gold Fund Class T
Management Fees	0.75%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.27%	[1]
Total Annual Operating Expenses (%)	1.27%

Example

The following example is intended to help you compare the cost of investing in the Gold Fund with the cost of investing in other mutual funds. This hypothetical example assumes you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem all shares at the end of those periods. The example also assumes the average annual return is 5% and operating expenses remain the same. Please keep in mind your actual costs may be higher or lower.

Sold

Expense Example	1 Year	3 Years	5 Years	10 Years
First Eagle Gold Fund | Class T | USD ($)	376	643	930	1,746

Held

Expense Example No Redemption	1 Year	3 Years	5 Years	10 Years
First Eagle Gold Fund | Class T | USD ($)	376	643	930	1,746

Portfolio Turnover Rate

The Gold Fund pays transaction costs, such as commissions, 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 annual Fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 15.82% of the average value of its portfolio.

Principal Investment Strategies

To achieve its objective of providing investors the opportunity to participate in the investment characteristics of gold, the Gold Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in gold and/or securities (which may include both equity and, to a limited extent, debt instruments) directly related to gold or issuers principally engaged in the gold industry, including securities of gold mining finance companies as well as operating companies with long-, medium- or short-life mines. Up to 20% of the Fund’s assets may be invested in equity and, to a limited extent, debt instruments unrelated to gold or the gold industry. The Fund may invest up to 20% of its total assets in debt securities. Investment decisions for the Fund are made without regard to the capitalization (size) of the companies in which it invests. The Fund may invest in any size company, including large, medium and smaller companies. The Fund may also invest in fixed-income instruments (without regard to credit rating or time to maturity), short-term debt instruments, other precious metals, and futures contracts related to precious metals. The Fund “counts” relevant derivative positions towards its “80% of assets” allocation, and in doing so, values each position at the price at which it is held on the Fund’s books.

An investment in the Gold Fund is not intended to be a complete investment program. However, many investors believe that, historically, a limited exposure to investments in gold or gold-related instruments may provide some offset against the market impact of political and economic disruptions, as well as relieve inflationary or deflationary pressures.

The Fund makes some investments through a special purpose trading subsidiary (the “Subsidiary”) and may invest up to 25% of its total assets in the Subsidiary. The Subsidiary is a wholly-owned and controlled subsidiary of the Fund, organized under the laws of the Cayman Islands as an exempted company. Generally, the Subsidiary will invest in commodities and related instruments (primarily gold bullion and other precious metals and related contracts). The Fund will invest in the Subsidiary in order to gain exposure to the commodities markets within the limitations of the federal tax laws, rules and regulations that apply to regulated investment companies. Unlike the Fund, the Subsidiary may invest without limitation in commodities and related instruments, however, the Subsidiary will comply with the same 1940 Act asset coverage requirements with respect to any investments in commodity-linked derivatives that are applicable to the Fund’s transactions in derivatives. In addition, to the extent applicable to the investment activities of the Subsidiary, the Subsidiary will be subject to the same fundamental investment restrictions and will follow the same compliance policies and procedures as the Fund. Compliance with the Fund’s investment restrictions generally will be measured on an aggregate basis in respect of the Fund’s and the Subsidiary’s portfolios. The Subsidiary will comply with the 1940 Act provisions governing affiliate transactions and custody of assets. The Fund is the sole shareholder of the Subsidiary and does not expect shares of the Subsidiary to be offered or sold to other investors.

Principal Investment Risks

As with any mutual fund investment, you may lose money by investing in the Gold Fund. The likelihood of loss may be greater if you invest for a shorter period of time. An investment in the Fund is not intended to be a complete investment program.

Principal risks of investing in the Gold Fund, which could adversely affect its net asset value and total return, are:

• Market Risk — The value of the Fund’s portfolio holdings may fluctuate in response to events specific to the companies or markets in which the Fund invests, as well as economic, political, or social events in the United States or abroad.

• Gold Risk — The Fund may invest in both physical gold and the securities of companies in the gold mining sector. Prices of gold-related issues are susceptible to changes in U.S. and foreign regulatory policies, taxes, currencies, mining laws, inflation, and various other market conditions.

• Derivatives Risk — Futures contracts or other “derivatives,” including hedging strategies, present risks related to their significant price volatility and risk of default by the counterparty to the contract. To date, derivatives have been used mainly under a hedging program intended to reduce the impact of foreign exchange rate changes on the Fund’s value.

• Foreign Investment Risk — The Fund may invest in foreign investments. Foreign investments are susceptible to less politically, economically and socially stable environments, foreign currency and exchange rate changes, and adverse changes to government regulations. These risks may be more pronounced with respect to investments in emerging markets. Because of the Gold Fund’s policy of investing primarily in gold, securities directly related to gold and/or of companies engaged in the gold industry, a substantial part of the Gold Fund’s assets will generally be invested in securities of companies domiciled or operating in one or more foreign countries, including emerging markets.

• Diversification Risk — The Fund is a non-diversified mutual fund, and as a result, an investment in the Fund may expose your money to greater risks than if you invest in a diversified fund. The Fund may invest in a limited number of companies and industries, therefore gains or losses in a particular security may have a greater impact on their share price.

• Small and Medium-Size Company Risk — The Fund may invest in small and medium-size companies, the securities of which can be more volatile in price than those of larger companies. Positions in smaller companies, especially when the Fund is a large holder of a small company’s securities, also may be more difficult or expensive to trade.

• Credit and Interest Rate Risk — The value of the Fund’s portfolio may fluctuate in response to the risk that the issuer of a bond or other instrument will not be able to make payments of interest and principal when due. The Fund may invest in debt instruments that are below investment grade, e.g., junk bonds, which are considered speculative, and carry a higher risk of default. In addition, fluctuations in interest rates can affect the value of debt instruments held by the Fund. An increase in interest rates tends to reduce the market value of debt instruments, while a decline in interest rates tends to increase their values. Longer-duration instruments tend to be more sensitive to interest rate changes than those with shorter durations.

• Currency Risk — Currency risk is the risk that foreign currencies will decline in value relative to that of the U.S. dollar and affect the Fund’s non-U.S. currencies or securities that trade in and receive revenue in non-U.S. currencies.

• Subsidiary Risk — By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The Subsidiary is not registered under the 1940 Act and is not subject to all of the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as expected and could adversely affect the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

Investment Results

The following information provides an indication of the risks of investing in the Gold Fund by showing changes in the Fund’s performance from year to year, and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of a broad measure of market performance. As with all mutual funds, past performance is not an indication of future performance (before or after taxes).

After-tax returns are calculated using the highest individual federal income tax rate for each year, and do not reflect the effect of state and local taxes. Actual after-tax returns depend on your individual tax situation. After-tax returns are not relevant to investors in tax-deferred accounts, such as 401(k) plans or individual retirement accounts.

Updated performance information is available at www.feim.com/individual-investors/fund/gold-fund or by calling 800.334.2143.

The following bar chart assumes reinvestment of dividends and distributions and does not reflect any sales charges. If sales charges were included, the returns would be lower.

To achieve its objective of providing investors the opportunity to participate in the investment characteristics of gold, the Gold Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in gold and/or securities (which may include both equity and, to a limited extent, debt instruments) directly related to gold or issuers principally engaged in the gold industry, including securities of gold mining finance companies as well as operating companies with long-, medium- or short-life mines. Up to 20% of the Fund’s assets may be invested in equity and, to a limited extent, debt instruments unrelated to gold or the gold industry. The Fund may invest up to 20% of its total assets in debt securities. Investment decisions for the Fund are made without regard to the capitalization (size) of the companies in which it invests. The Fund may invest in any size company, including large, medium and smaller companies. The Fund may also invest in fixed-income instruments (without regard to credit rating or time to maturity), short-term debt instruments, other precious metals, and futures contracts related to precious metals.

This hypothetical example assumes you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem all shares at the end of those periods.

Held

Expense Example No Redemption	1 Year	3 Years	5 Years	10 Years
First Eagle Global Income Builder Fund | Class T | USD ($)	367	615	883	1,646

Portfolio Turnover Rate

There are transaction costs due to the bid/ask spread in the case of bonds or commissions in the case of stocks. The Global Income Builder Fund pays transaction costs when the Fund 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 annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 29.76% of the average value of its portfolio.

Principal Investment Strategies

To achieve its objective of current income generation and long-term growth of capital, the Global Income Builder Fund will normally invest primarily in common stocks of U.S. and foreign companies that offer attractive dividend yields and a range of fixed income instruments, including high-yield, below investment grade instruments (commonly referred to as “junk bonds”), investment grade instruments and sovereign debt, from markets in the United States and multiple countries around the world.

Investment decisions for the Global Income Builder Fund are made without regard to the capitalization (size) of the companies in which it invests. The Fund may invest in any size company, including large, medium and smaller companies. Under normal circumstances, the Fund anticipates it will allocate a substantial amount of its assets to income-producing securities. That generally means that approximately 80% or more of the Fund’s net assets (plus any borrowings for investment purposes) will be allocated to such investments, which may include dividend paying equities, both high-yield (below investment grade) and investment grade debt, sovereign bonds, and various short-term debt instruments. The Fund may invest in securities with any maturity or investment rating, as well as unrated securities. The Fund may also invest (typically for hedging purposes) in derivative instruments such as options, futures contracts and options on futures contracts, credit default swaps, and swaps and options on indices.

Additionally, under normal circumstances, the Fund anticipates it will allocate a substantial amount of its assets to foreign investments. That generally means that approximately 40% or more of the Fund’s net assets (plus any borrowings for investment purposes) will be allocated to foreign investments (unless market conditions are not deemed favorable by the Fund, in which case the Fund expects to invest at least 30% of its net assets (plus any borrowings for investment purposes) in foreign investments). For purposes of these 80%, 40% and 30% of assets allocations, the Fund “counts” relevant derivative positions on investments, and in doing so, values each position at the price at which it is held on the Fund’s books.

The investment philosophy and strategy of the Global Income Builder Fund can be broadly characterized as a “value” approach, as it seeks a “margin of safety” in each investment purchase with the goal being to avoid permanent impairment of capital (as opposed to temporary losses in share value relating to shifting investor sentiment or other normal share price volatility). With respect to equity investments in particular, a discount to “intrinsic value” is sought even for what appear to be the best of businesses, with a deeper discount demanded for companies that we view as under business model, balance sheet, management or other stresses. “Intrinsic value” is based on our judgment of what a prudent and rational business buyer would pay in cash for all of the company in normal markets. Investments in debt instruments are made after careful scrutiny of the underlying creditworthiness of the issuer, taking into account such factors as cash flow generation, liquidation value and structural protections. The Global Income Builder Fund seeks to own debt instruments that offer an attractive “margin of safety” on principal repayment relative to the total expected return of the security.

Principal Investment Risks

As with any mutual fund investment, you may lose money by investing in the Global Income Builder Fund. The likelihood of loss may be greater if you invest for a shorter period of time. An investment in the Fund is not intended to be a complete investment program.

Principal risks of investing in the Fund, which could adversely affect its net asset value and total return, are:

• Market Risk — The value of the Fund’s portfolio holdings may fluctuate in response to events specific to the companies or markets in which the Fund invests, as well as economic, political, or social events in the United States or abroad.

• Foreign Investment Risk — The Fund will invest in foreign investments. Foreign investments can be susceptible to less politically, economically and socially stable environments, foreign currency and exchange rate changes, and adverse changes to government regulations.

• Credit and Interest Rate Risk — The value of the Fund’s portfolio may fluctuate in response to the risk that the issuer of a bond or other instrument will not be able to make payments of interest and principal when due. In addition, fluctuations in interest rates can affect the value of debt instruments held by the Fund. An increase in interest rates tends to reduce the market value of debt instruments, while a decline in interest rates tends to increase their values. Longer-duration instruments tend to be more sensitive to interest rate changes than those with shorter durations.

• Prepayment Risk — Certain instruments, especially mortgage-backed securities, for example, are susceptible to the risk of prepayment by borrowers. During a period of declining interest rates, homeowners may refinance their high-rate mortgages and prepay the principal. Cash from these prepayments flows through to prepay the mortgage-backed securities, necessitating reinvestment in other assets, which may lower returns. Asset-backed securities, which are subject to risks similar to those of mortgage-backed securities, are also structured like mortgage-backed securities, but instead of mortgage loans or interests in mortgage loans, the underlying assets may include such items as motor vehicle installment sales or installment loan contracts, leases of various types of real and personal property and receivables from credit card agreements. The market for mortgage-backed and asset-backed instruments may be volatile and limited, which may make them difficult to buy or sell.

• Changes in Debt Ratings Risk — If a rating agency gives a debt instrument a lower rating, the value of the instrument may decline because investors may demand a higher rate of return.

• Convertible Security Risk — Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. Convertible securities may gain or lose value due to changes in the issuer’s operating results, financial condition and credit rating and changes in interest rates and other general economic, industry and market conditions.

• High Yield Risk — The Fund intends to invest in high yield instruments (commonly known as “junk bonds”) which may be subject to greater levels of interest rate, credit (including issuer default) and liquidity risk than investment grade instruments and may experience extreme price fluctuations. The securities of such companies may be considered speculative and the ability of such companies to pay their debts on schedule may be uncertain.

• Illiquid Investment Risk — Holding illiquid securities restricts or otherwise limits the ability for the Fund to freely dispose of its investments for specific periods of time. The Fund might not be able to sell illiquid securities at its desired price or time. Changes in the markets or in regulations governing the trading of illiquid instruments can cause rapid changes in the price or ability to sell an illiquid security. The market for lower-quality debt instruments, including junk bonds and leveraged loans, is generally less liquid than the market for higher-quality debt instruments.

• Derivatives Risk — Futures contracts or other “derivatives,” including hedging strategies, present risks related to their significant price volatility and risk of default by the counterparty to the contract. To date, derivatives have been used mainly under a hedging program that seeks to reduce the impact of foreign exchange rate changes on the Fund’s value. The Fund may at times also purchase derivatives linked to relevant market indices as either a hedge or for investment purposes.

• Currency Risk — Currency risk is the risk that foreign currencies will decline in value relative to that of the U.S. dollar and affect the Fund’s non-U.S. currencies or securities that trade in and receive revenue in non-U.S. currencies.

• Small and Medium-Size Company Risk — The Fund may invest in small and medium-size companies, the securities of which can be more volatile in price than those of larger companies. Positions in smaller companies, especially when the Fund is a large holder of a small company’s securities, also may be more difficult or expensive to trade.

• Bank Loan Risk — The Fund may invest in bank loans. These investments potentially expose the Fund to the credit risk of the underlying borrower, and in certain cases, of the financial institution. The Fund’s ability to receive payments in connection with the loan depends primarily on the financial condition of the borrower. The market for bank loans may be illiquid and the Fund may have difficulty selling them, especially in the case of leveraged loans, which can be difficult to value. In addition, bank loans often have contractual restrictions on resale, which can delay the sale and adversely impact the sale price. At times, the Fund may decline to receive non-public information relating to loans, which could disadvantage the Fund relative to other investors.

• Real Estate Industry Risk — The Fund may invest in real estate investment trusts (“REITs”), which are subject to risks affecting the real estate industry generally (including market conditions, competition, property obsolescence, changes in interest rates and casualty to real estate), as well as risks specifically affecting REITs (the quality and skill of REIT management and the internal expenses of the REIT).

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

Investment Results

The following information provides an indication of the risks of investing in the Global Income Builder Fund by showing changes in the Fund’s performance from year to year, and by showing how the Fund’s average annual returns for the periods shown compare with those of a broad measure of market performance. As with all mutual funds, past performance is not an indication of future performance (before or after taxes).

After-tax returns are calculated using the highest individual federal income tax rate for each year, and do not reflect the effect of state and local taxes. Actual after-tax returns depend on your individual tax situation. After-tax returns are not relevant to investors in tax-deferred accounts, such as 401(k) plans or individual retirement accounts.

Updated performance information is available at www.feim.com/individual-investors/fund/global-income-builder-fund or by calling 800.334.2143.

The following bar chart assumes reinvestment of dividends and distributions and does not reflect any sales charges. If sales charges were included, the returns would be lower.

There are transaction costs due to the bid/ask spread in the case of bonds or commissions in the case of stocks. The Global Income Builder Fund pays transaction costs when the Fund 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 annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 29.76% of the average value of its portfolio.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

To achieve its objective of current income generation and long-term growth of capital, the Global Income Builder Fund will normally invest primarily in common stocks of U.S. and foreign companies that offer attractive dividend yields and a range of fixed income instruments, including high-yield, below investment grade instruments (commonly referred to as “junk bonds”), investment grade instruments and sovereign debt, from markets in the United States and multiple countries around the world.

Investment decisions for the Global Income Builder Fund are made without regard to the capitalization (size) of the companies in which it invests. The Fund may invest in any size company, including large, medium and smaller companies. Under normal circumstances, the Fund anticipates it will allocate a substantial amount of its assets to income-producing securities. That generally means that approximately 80% or more of the Fund’s net assets (plus any borrowings for investment purposes) will be allocated to such investments, which may include dividend paying equities, both high-yield (below investment grade) and investment grade debt, sovereign bonds, and various short-term debt instruments. The Fund may invest in securities with any maturity or investment rating, as well as unrated securities. The Fund may also invest (typically for hedging purposes) in derivative instruments such as options, futures contracts and options on futures contracts, credit default swaps, and swaps and options on indices.

Portfolio Turnover Rate

There are transaction costs due to the bid/ask spread in the case of bonds or commissions in the case of stocks. The High Yield Fund pays transaction costs, such as commissions, when the Fund 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 annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 36.88% of the average value of its portfolio.

Principal Investment Strategies

To pursue its investment objective, the High Yield Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in high yield, below investment-grade securities (commonly referred to as “junk bonds”) and instruments. Such high yield instruments may include corporate bonds and loans, municipal bonds, and mortgage-backed and asset-backed securities. The Fund may invest in, and count for the purposes of this 80% allotment, unrated securities or other instruments deemed by the Fund’s Adviser to be below investment grade. The Fund “counts” relevant derivative positions towards its “80% of assets” allocation and, in doing so, values each position at the price at which it is held on the Fund’s books.

The Fund may invest its assets in the securities of both U.S. and foreign issuers. The Fund may also invest (typically for hedging purposes) in derivative instruments such as options, futures contracts and options on futures contracts, credit default swaps, and swaps and options on indices.

The Fund may invest in securities with any investment rating or time to maturity, as well as unrated securities. An investment in the Fund is not intended to be a complete investment program.

Principal Investment Risks

As with any mutual fund investment, you may lose money by investing in the High Yield Fund. The likelihood of loss may be greater if you invest for a shorter period of time. An investment in the Fund is not intended to be a complete investment program.

Principal risks of investing in the Fund, which could adversely affect its net asset value and total return, are:

• Credit and Interest Rate Risk — The value of the Fund’s portfolio may fluctuate in response to the risk that the issuer of a bond or other instrument will not be able to make payments of interest and principal when due. In addition, fluctuations in interest rates can affect the value of debt instruments held by the Fund. An increase in interest rates tends to reduce the market value of debt instruments, while a decline in interest rates tends to increase their values. Longer-duration instruments tend to be more sensitive to interest rate changes than those with shorter durations.

• High Yield Risk — The Fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) under normal market conditions in high yield instruments (commonly known as “junk bonds”) which may be subject to greater levels of interest rate, credit (including issuer default) and liquidity risk than investment grade securities and may experience extreme price fluctuations. The securities of such companies may be considered speculative and the ability of such companies to pay their debts on schedule may be uncertain.

• Market Risk — The value of the Fund’s portfolio holdings may fluctuate in response to events specific to the companies or markets in which the Fund invests, as well as economic, political, or social events in the United States or abroad.

• Foreign Investment Risk — The Fund may invest in foreign investments. Foreign investments can be susceptible to less politically, economically and socially stable environments, foreign currency and exchange rate changes, and adverse changes to government regulations.

• Convertible Security Risk — Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. Convertible securities may gain or lose value due to changes in the issuer’s operating results, financial condition, credit rating and changes in interest rates and other general economic, industry and market conditions.

• Illiquid Investment Risk — Holding illiquid securities restricts or otherwise limits the ability for the Fund to freely dispose of its investments for specific periods of time. The Fund might not be able to sell illiquid securities at its desired price or time. Changes in the markets or in regulations governing the trading of illiquid instruments can cause rapid changes in the price or ability to sell an illiquid security. The market for lower-quality debt instruments, including junk bonds, is generally less liquid than the market for higher-quality debt instruments.

• Prepayment Risk — Certain instruments, especially mortgage-backed securities, for example, are susceptible to the risk of prepayment by borrowers. During a period of declining interest rates, homeowners may refinance their high-rate mortgages and prepay the principal. Cash from these prepayments flows through to prepay the mortgage-backed securities, necessitating reinvestment in other assets, which may lower returns. Asset-backed securities, which are subject to risks similar to those of mortgage-backed securities, are also structured like mortgage-backed securities, but instead of mortgage loans or interests in mortgage loans, the underlying assets may include such items as motor vehicle installment sales or installment loan contracts, leases of various types of real and personal property and receivables from credit card agreements. The market for mortgage-backed and asset-backed instruments may be volatile and limited, which may make them difficult to buy or sell.

• Bank Loan Risk — The Fund may invest in bank loans. These investments potentially expose the Fund to the credit risk of the underlying borrower, and in certain cases, of the financial institution. The Fund’s ability to receive payments in connection with the loan depends primarily on the financial condition of the borrower. The market for bank loans may be illiquid and the Fund may have difficulty selling them, especially in the case of leveraged loans, which can be difficult to value. In addition, bank loans often have contractual restrictions on resale, which can delay the sale and adversely impact the sale price. At times, the Fund may decline to receive non-public information relating to loans, which could disadvantage the Fund relative to other investors.

• Changes in Debt Ratings Risk — If a rating agency gives a debt instrument a lower rating, the value of the instrument may decline because investors may demand a higher rate of return.

• Derivatives Risk — Futures contracts or other “derivatives,” including hedging strategies, present risks related to their significant price volatility and risk of default by the counterparty to the contract. The Fund may use derivatives in seeking to reduce the impact of foreign exchange rate changes on the Fund’s value. The Fund may at times also purchase derivatives linked to relevant market indices as either a hedge or for investment purposes.

• Currency Risk — Currency risk is the risk that foreign currencies will decline in value relative to that of the U.S. dollar and affect the Fund’s non-U.S. currencies or securities that trade in and receive revenue in non-U.S. currencies.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

Investment Results

The High Yield Fund commenced operations in its present form on or about December 30, 2011 and is the successor to the Old Mutual High Yield Fund (the “Predecessor Fund”) pursuant to a reorganization on or about that same date. The Predecessor Fund had similar investment objectives and strategies as the Fund, but was managed by another investment adviser.

The following information provides an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year, and by showing how the Fund’s average annual returns for 1 and 5 years and since inception compare with those of a broad measure of market performance.

As with all mutual funds, past performance is not an indication of future performance (before or after taxes).

After-tax returns are calculated using the highest individual federal income tax rate for each year, and do not reflect the effect of state and local taxes. Actual after-tax returns depend on your individual tax situation. After-tax returns are not relevant to investors in tax-deferred accounts, such as 401(k) plans or individual retirement accounts.

Updated performance information is available at www.feim.com/individual-investors/fund/high-yield-fund or by calling 800.334.2143.

The following bar chart assumes reinvestment of dividends and distributions and does not reflect any sales charges. If sales charges were included the returns would be lower.

Average Annual Total Returns as of December 31, 2016

The bar chart above and table below disclose returns only for Class I shares (which are not offered by this prospectus). Returns shown for Class I shares assume commencement of operations on November 19, 2007, which is the date of organization of the Predecessor Fund and includes the returns of the Predecessor Fund for periods prior to January 1, 2012.

While no information is shown for the Class T shares (because they are newly organized), annual returns for Class T shares would have been substantially similar to those shown here. Class T shares are invested in the same portfolio of securities and the annual returns would differ only to the extent that Class T shares do not have the same expenses. Because the Class T share expenses are anticipated to be higher than Class I, Class T share performance would be lower.

Fund of America pays transaction costs, such as commissions, 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 annual Fund of America operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, Fund of America’s portfolio turnover rate was 55.06% of the average value of its portfolio.

Principal Investment Strategies

To achieve its objective of capital appreciation, Fund of America will primarily invest in domestic stocks and, to a lesser extent, debt and foreign equity instruments. Normally, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) are invested in domestic equity and debt instruments. Equity securities include common stocks, preferred stocks, convertible securities and warrants. The Fund may also invest in repurchase agreements and derivatives.

Derivatives include investing in options, futures and swaps and related products. Specifically, the Fund may enter into interest rate, credit default, currency, equity, fixed income and index swaps and the purchase or sale of related caps, floors and collars.

In addition, the Fund may enter into options on securities and on stock indices to limit the Fund’s investment risk and augment its investment return. Further, the Fund may write “covered” call options on equity or debt securities and on stock indices in seeking to enhance investment return or to hedge against declines in the prices of portfolio securities or may write put options to hedge against increases in the prices of securities which it intends to purchase. The Fund also may write call options on broadly based stock and bond market indices if at the time of writing it holds a portfolio of stocks or bonds listed on such index. Finally, the Fund may utilize futures contracts and options on futures on securities exchanges or in the over-the-counter market.

The Fund may enter into certain types of repurchase agreements, primarily as a cash management strategy.

Normally, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested in domestic equity and debt instruments. The Fund “counts” derivative positions on these instruments for purposes of this 80% allocation, and in doing so, values each position at the price at which it is held on the Fund’s books.

The investment philosophy and strategy of Fund of America can be broadly characterized as a bottom-up, event-driven approach to choose stocks that it believes are undervalued and should perform well. In a bottom-up approach, companies and securities are researched and chosen individually. In an event-driven approach, one looks for companies that appear to be undervalued in relation to their potential value in light of positive corporate changes. Signals of corporate change can be management changes, large share repurchases, potential acquisitions or mergers. If changes are successful, these companies should realize a rise in the stock price. Fund of America invests in the securities of companies that it believes are undervalued relative to their overall financial and managerial strength. Investment decisions for the Fund are made without regard to the capitalization (size) of the companies in which it invests. The Fund may invest in any size company, including large, medium and smaller companies. The Fund may invest in debt securities generally without regard to their credit rating or time to maturity. However, the Fund has no current intention of investing more than 5% of its net assets in high yield bonds.

Principal Investment Risks

As with any mutual fund investment, you may lose money by investing in Fund of America. The likelihood of loss may be greater if you invest for a shorter period of time. An investment in the Fund is not intended to be a complete investment program.

Principal risks of investing in Fund of America, which could adversely affect its net asset value and total return, are:

• Market Risk — The value of the Fund’s portfolio holdings may fluctuate in response to events specific to the companies or markets in which Fund of America invests, as well as economic, political, or social events in the United States or abroad.

• Event-Driven Style Risk — The event-driven investment style carries the additional risk that the event anticipated occurs later than expected, does not occur at all, or does not have the desired effect on the market price of the securities.

• Diversification Risk — The Fund is a non-diversified mutual fund, and as a result, an investment in Fund of America may expose your money to greater risks than if you invest in a diversified fund. Fund of America will invest in a limited number of companies and industries, therefore gains or losses in a particular security may have a greater impact on their share price.

• Credit and Interest Rate Risk — The value of the Fund’s portfolio may fluctuate in response to the risk that the issuer of a bond or other instrument will not be able to make payments of interest and principal when due. The Fund may invest in debt instruments that are below investment grade, e.g., junk bonds, which are considered speculative, and carry a higher risk of default. In addition, fluctuations in interest rates can affect the value of debt instruments held by the Fund. An increase in interest rates tends to reduce the market value of debt instruments, while a decline in interest rates tends to increase their values. Longer-duration instruments tend to be more sensitive to interest rate changes than those with shorter durations.

• Small and Medium-Size Company Risk — The Fund may invest in small and medium-size companies, the securities of which can be more volatile in price than those of larger companies. Positions in smaller companies, especially when the Fund is a large holder of a small company’s securities, also may be more difficult or expensive to trade.

• Repurchase Agreements Risk — The Fund may enter into certain types of repurchase agreements, primarily as a cash management strategy. If the seller fails to repurchase the security and the market value declines, Fund of America may lose money.

• Options Risk — The Fund may engage in various options transactions in which Fund of America seeks to limit investment risk or increase investment returns by purchasing the right to buy or sell, or by selling the obligation to buy or sell, a security at a set price in the future. The Fund pays a premium when buying options and receives a premium when selling options. When trading options, the Fund may incur losses or forego otherwise realizable gains if market prices do not move as expected.

• Foreign Investment Risk — The Fund may invest in foreign investments. Foreign investments are susceptible to less politically, economically and socially stable environments, foreign currency and exchange rate changes, and adverse changes to government regulations.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

Investment Results

The following information provides an indication of the risks of investing in Fund of America by showing changes in the Fund’s performance from year to year, and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of a broad measure of market performance. As with all mutual funds, past performance is not an indication of future performance (before or after taxes).

After-tax returns are calculated using the highest individual federal income tax rate for each year, and do not reflect the effect of state and local taxes. Actual after-tax returns depend on your individual tax situation. After-tax returns are not relevant to investors in tax-deferred accounts, such as 401(k) plans or individual retirement accounts.
