Strategy Narrative [Text Block]

oef_StrategyNarrativeTextBlock

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 debt instruments (e.g., notes and bonds) 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 (including American Depositary Receipts, Global Depositary Receipts and European Depositary Receipts). 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 (generally market price, but anticipates valuing each such position for purposes of assessing compliance with this test at notional value in connection with new rules requiring that treatment, which come into effect in 2025).

The investment philosophy and strategy of the Global Fund can be broadly characterized as a “value” approach, as it generally seeks a “margin of safety” in its investment purchases 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 futures contracts).

Performance Narrative [Text Block]

oef_PerformanceNarrativeTextBlock

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 the periods shown compare with those of one or more broad measures of market performance, which have characteristics relevant to the Fund’s investment strategy. The index is described in the Fund Indices section. 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 U.S. 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.firsteagle.com/funds/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.

Performance Table Narrative

oef_PerformanceTableNarrativeTextBlock

The following table discloses after-tax returns only for Class A shares. After-tax returns for Class C, Class I and Class R6 shares will vary. While only partial information is shown for Class R6 shares (because it is more recently organized), annual returns for Class R6 shares would have been substantially similar to those shown here. Class R6 shares are invested in the same portfolio of securities and the annual returns differ only to the extent that Class R6 shares do not have the same expenses as the classes for which more extended performance is shown. Comparative expense information is in the Fees and Expenses table.

Geographic Investment Risk — To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. While the Fund reserves the right to dynamically allocate its assets across countries and regions, listed below are some of the geographies to which the Fund has significant exposure as of the date of this Prospectus.

European Risk — The Fund’s investments may subject it to the risks associated with investing in the European markets, including the risks associated with the United Kingdom’s exit from the European Union (“Brexit”) and the war in Ukraine. Investments in a single region, even though representing a number of different countries within the region, may be affected by common economic forces and other factors. Further, political or economic disruptions in European countries, even in countries in which the Fund is not invested, may adversely affect security values and thus the Fund’s holdings. The impact of Brexit on the United Kingdom and European economies is still not fully understood, but could result in increased volatility and illiquidity and lower economic growth for companies that rely significantly on the United Kingdom and/or Europe for their business activities and revenues. Any further exits from the European Union, or an increase in the belief that such exits are likely or possible, would likely cause additional market disruption globally and introduce new legal and regulatory uncertainties. Recent political developments in the United States have raised potential implications for the current trade arrangements between the United States and Europe, which could negatively affect the value of European securities.

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. The Fund considers small companies to be companies with market capitalizations of less than $1 billion and medium-size companies to have market capitalizations of less than $10 billion.

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. Gold-related investments as a group have not performed as well as the stock market in general during periods when the U.S. dollar is strong, inflation is low and general economic conditions are stable. In addition, returns on gold-related investments have traditionally been more volatile than investments in broader equity or debt markets.

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. A futures contract is considered a derivative because it derives its value from the price of the underlying security or financial index. The prices of futures contracts can be volatile and futures contracts may lack liquidity. In addition, there may be imperfect or even negative correlation between the price of a futures contract and the price of the underlying securities or financial index.

Value Investment Strategy Risk — An investment made at a perceived “margin of safety” or “discount to intrinsic or fundamental value” can trade at prices substantially lower than when an investment is made, so that any perceived “margin of safety” or “discount to value” is no guarantee against loss. “Value” investments, as a category, or entire industries or sectors associated with such investments, may lose favor with investors as compared to those that are more “growth” oriented. In such an event, the Fund’s investment returns would be expected to lag relative to returns associated with more growth-oriented investment strategies. Investing in or having exposure to “value” securities presents the risk that such securities may never reach what the Adviser believes are their full market values.

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.
