Strategy, Narrative rr_StrategyNarrativeTextBlock

Davis Selected Advisers, L.P. ("Davis Advisors" or the "Adviser"), the Fund's investment adviser, uses the Davis Investment Discipline to invest Davis Global Fund's portfolio principally in common stocks (including indirect holdings of common stock through depositary receipts) issued by both United States and foreign companies, including countries with developed or emerging markets. The Fund may invest in large, medium, or small companies without regard to market capitalization. The Fund will invest significantly (at least 40% of total assets under normal market conditions and at least 30% of total assets if market conditions are not deemed favorable) in issuers: (i) organized or located outside of the U.S.; (ii) whose primary trading market is located outside the U.S.; or (iii) doing a substantial amount of business outside the U.S., which the Fund considers to be a company that derives at least 50% of its revenue from business outside the U.S. or has at least 50% of its assets outside the U.S. Under normal market conditions the Fund will invest in issuers representing at least three different countries.

Davis Investment Discipline. Davis Advisors manages equity funds using the Davis Investment Discipline. Davis Advisors conducts extensive research to try to identify businesses that possess characteristics that Davis Advisors believes foster the creation of long-term value, such as proven management, a durable franchise and business model, and sustainable competitive advantages. Davis Advisors aims to invest in such businesses when they are trading at discounts to their intrinsic worth. Davis Advisors emphasizes individual stock selection and believes that the ability to evaluate management is critical. Davis Advisors routinely visits managers at their places of business in order to gain insight into the relative value of different businesses. Such research, however rigorous, involves predictions and forecasts that are inherently uncertain. After determining which companies Davis Advisors believes the Fund should own, Davis Advisors then turns its analysis to determining the intrinsic value of those companies' equity securities. Davis Advisors seeks companies whose equity securities can be purchased at a discount from Davis Advisors' estimate of the company's intrinsic value based upon fundamental analysis of cash flows, assets and liabilities, and other criteria that Davis Advisors deems to be material on a company-by-company basis. Davis Advisors' goal is to invest in companies for the long-term (ideally five years or longer, although this goal may not be met). Davis Advisors considers selling a company's equity securities if the securities' market price exceeds Davis Advisors' estimates of intrinsic value, if the ratio of the risks and rewards of continuing to own the company's equity securities is no longer attractive, to raise cash to purchase a more attractive investment opportunity, to satisfy net redemptions or other purposes.

Risk, Heading rr_RiskHeading Principal Risks of Investing in Davis Global Fund
Risk, Narrative rr_RiskNarrativeTextBlock

You may lose money by investing in the Fund. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. The principal risks of investing in the Fund are:

  • Common Stock Risk. Common stock represents an ownership position in a company. An adverse event may have a negative impact on a company and could result in a decline in the price of its common stock. Common stock is generally subordinate to an issuer's other securities, including preferred, convertible, and debt securities.
  • Depositary Receipts Risk. Depositary receipts, consisting of American Depositary Receipts, European Depositary Receipts and Global Depositary Receipts, are certificates evidencing ownership of shares of a foreign issuer. Depositary receipts are subject to many of the risks associated with investing directly in foreign securities. Depositary receipts may trade at a discount, or a premium, to the underlying security and may be less liquid than the underlying securities listed on an exchange.
  • Emerging Market Risk. Securities of issuers in emerging and developing markets may offer special investment opportunities, but present risks relating to political, economic or regulatory conditions not found in more mature markets, such as government controls on foreign investments, government restrictions on the transfer of securities and less developed trading markets, exchanges, reporting standards and legal and accounting systems.
  • Fees and Expenses Risk. The Fund may not earn enough through income and capital appreciation to offset the operating expenses of the Fund. All mutual funds incur operating fees and expenses. Fees and expenses reduce the return that a shareholder may earn by investing in a fund, even when a fund has favorable performance. A low-return environment, or a bear market, increases the risk that a shareholder may lose money.
  • Foreign Country Risk. Securities of foreign companies (including ADRs) may be subject to greater risk as foreign economies may not be as strong or diversified, foreign political systems may not be as stable, and foreign financial reporting standards may not be as rigorous as they are in the United States. There may also be less information publicly available regarding the non-U.S. issuers and their securities. These securities may be less liquid (and, in some cases, may be illiquid) and could be harder to value than more liquid securities.
  • Foreign Currency risk. The change in value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of securities denominated in that foreign currency. For example, when the Fund holds a security that is denominated in a foreign currency, a decline of that foreign currency against the U.S. dollar would generally cause the value of the Fund's shares to decline.
  • Headline Risk. The Fund may invest in a company when the company becomes the center of controversy after receiving adverse media attention concerning its operations, long-term prospects, management or for other reasons. While Davis Advisors researches companies subject to such contingencies, it cannot be correct every time and the company's stock may never recover or may become worthless.
  • Large-Capitalization Companies risk. Companies with $10 billion or more in market capitalization are considered by the Adviser to be large-capitalization companies. Large-capitalization companies generally experience slower rates of growth in earnings per share than do mid-and small-capitalization companies.
  • Manager Risk. Poor security selection or focus on securities in a particular sector, category or group of companies may cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective. Even if the Adviser implements the intended investment strategies, the implementation of the strategies may be unsuccessful in achieving the Fund's investment objective.
  • Mid- and Small-Capitalization Companies risk. Companies with less than $10 billion in market capitalization are considered by the Adviser to be mid- or small-capitalization companies. Mid- and small-capitalization companies typically have more limited product lines, markets and financial resources than larger companies, and their securities may trade less frequently and in more limited volume than those of larger, more mature companies.
  • Stock Market Risk. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices, including the possibility of sharp declines.

While Davis Advisors researches companies subject to such contingencies, it cannot be correct every time and the company's stock may never recover or may become worthless.
  • Large-Capitalization Companies risk. Companies with $10 billion or more in market capitalization are considered by the Adviser to be large-capitalization companies. Large-capitalization companies generally experience slower rates of growth in earnings per share than do mid- and small-capitalization companies.
  • Manager Risk. Poor security selection or focus on securities in a particular sector, category or group of companies may cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective. Even if the Adviser implements the intended investment strategies, the implementation of the strategies may be unsuccessful in achieving the Fund's investment objective.
  • Mid- and Small-Capitalization Companies risk. Companies with less than $10 billion in market capitalization are considered by the Adviser to be mid- or small-capitalization companies. Mid- and small-capitalizationcompanies typically have more limited product lines, markets and financial resources than larger companies, and their securities may trade less frequently and in more limited volume than those of larger, more mature companies.
  • Stock Market Risk. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices, including the possibility of sharp declines.

After-tax returns are shown only for Class A shares; after-tax returns for other share classes will vary.
