Davis Equity Portfolio | Foreign Country Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Foreign Country Risk. Securities of foreign companies (including Depositary Receipts) 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.
Davis Equity Portfolio | China Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
China Risk – Generally. Investment in Chinese securities may subject the Fund to risks that are specific to China. China may be subject to significant amounts of instability, including, but not limited to, economic, political, and social instability. China’s economy may differ from the U.S. economy in certain respects, including, but not limited to, general development, level of government involvement, wealth distribution, and structure.
The Fund may invest in securities issued by variable interest entities (“VIEs”), which are subject to the investment risks associated with the underlying Chinese operating company. A VIE enters into service contracts and other contracts with the Chinese operating company, which provide the VIE with exposure to the company. Although the VIE has no equity ownership of the Chinese operating company, the contractual arrangements permit the VIE to consolidate the Chinese operating company into its financial statements. Intervention by the Chinese government with respect to VIEs could significantly affect the Chinese operating company’s performance and the enforceability of the VIE’s contractual arrangements with the Chinese company.
Davis Equity Portfolio | Headline Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
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.
Davis Equity Portfolio | Large-Capitalization Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
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.
Davis Equity Portfolio | Manager Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
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.
Davis Equity Portfolio | Depositary Receipts Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
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.
Davis Equity Portfolio | Emerging Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
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. These securities may be more volatile and less liquid, which may also make them more difficult to value than securities in countries with developed economies.
Davis Equity Portfolio | Fees and Expenses Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
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.
Davis Equity Portfolio | Foreign Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
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.
Davis Equity Portfolio | Mid- and Small-Capitalization Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
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.
