Operating Expenses, Caption	rr_OperatingExpensesCaption	Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover, Heading	rr_PortfolioTurnoverHeading	Portfolio Turnover.
Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The 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.
Expense Example, Heading	rr_ExpenseExampleHeading	Example.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategy.
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a non-diversified portfolio of publicly-traded equity securities issued by U.S. and non-U.S. companies. The Fund will normally be diversified among at least three different countries. The Fund's subadviser, Magellan Asset Management Limited doing business as MFG Asset Management ("MFG Asset Management"), seeks to identify high quality companies at attractive prices while integrating an in depth macroeconomic understanding in order to manage risk. The Fund will normally hold a concentrated number (generally 20 to 40) of companies, selected on a value basis and typically with a market capitalization in excess of U.S. $10 billion at the time of purchase.
Risk, Heading	rr_RiskHeading	Principal Investment Risks.
Risk, Narrative	rr_RiskNarrativeTextBlock	Market Risks. The Fund's investments are subject to market risk, which may cause the value of the Fund's investments to decline. If the value of the Fund's investments goes down, the share price of the Fund will go down, and you may lose money. U.S. and international markets have experienced extreme volatility, reduced liquidity, credit downgrades, increased likelihood of default and valuation difficulties in recent years. Equity Securities Risks. Common stocks and other equity securities held by the Fund will fluctuate in value based on the earnings of the company and on general industry and market conditions, leading to fluctuations in the Fund's share price. Non-Diversification Risks. The Fund is non-diversified, which means it may invest more of its assets in a smaller number of companies than funds that are diversified. Gains or losses on a single stock may have greater impact on the Fund than for other funds that invest in a greater number of companies. Stock Selection Risks. The stocks selected for the Fund may decline in value or not increase in value when the stock market in general is rising. Value Investing Risks. MFG Asset Management invests in companies that it believes are undervalued. Such companies may never increase in price or pay dividends, or may decline even further if the market fails to recognize the company's value. Large Capitalization Risks. Large-cap companies perform differently from, and at times and for extended periods of time worse than, stocks of mid- and small-cap companies. Larger, more established companies may be unable to respond quickly to new competitive challenges. Foreign Securities Risks. Investments in securities of foreign companies involve additional risks, including less liquidity, currency-rate fluctuations, political and economic instability and differences in financial reporting standards and securities market regulation. Currency Risks. The value of the Fund's foreign holdings as measured in U.S. dollars may be affected unfavorably by changes in foreign currency exchange rates. The Fund may also incur costs in connection with conversions between various currencies. Management Risks. The Fund is subject to management risk as an actively-managed investment portfolio and depends on the decisions of the portfolio manager to produce the desired results.
Risk, Lose Money	rr_RiskLoseMoney	If the value of the Fund's investments goes down, the share price of the Fund will go down, and you may lose money.
Risk, Nondiversified Status	rr_RiskNondiversifiedStatus	The Fund is non-diversified, which means it may invest more of its assets in a smaller number of companies than funds that are diversified. Gains or losses on a single stock may have greater impact on the Fund than for other funds that invest in a greater number of companies.
