of the value of your investment)

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys or 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 transaction costs, which are not reflected in the Annual Fund Operating Expenses or in the Examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 63% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in an international portfolio of equity securities of companies selected by the Adviser for their growth potential within various market sectors. Examples of the types of market sectors in which the Fund may invest include, but are not limited to, information technology (which includes telecommunications), health care, financial services, infrastructure, energy and natural resources, and consumer groups. The Adviser’s growth analysts seek to identify companies or industries that other investors have underestimated earnings potential--for example, some hidden earnings driver (including, but not limited to, reduced competition, market share gain, better margin trend, increased customer base, or similar factors) that would cause a company to grow faster than market forecasts.

Sector heads are responsible for the construction of the portfolio. This investment team allocates the Fund’s investments among broad sector groups utilizing the fundamental company research conducted by the Adviser’s large internal research staff, assessing the current and forecasted investment opportunities and conditions, as well as diversification and risk considerations. The investment team may vary the percentage allocations among market sectors and may change the market sectors in which the Fund invests as companies’ potential for growth within a sector matures and new trends for growth emerge.

The Fund invests, under normal circumstances, in the equity securities of companies located in at least three countries (and normally substantially more) other than the United States. The Fund invests in securities of companies in both developed and emerging market countries. Geographic distribution of the Fund’s investments among countries or regions also will be a product of the stock selection process rather than a pre-determined allocation. The Fund may also invest in synthetic foreign equity securities, which are various types of warrants used internationally that entitle a holder to buy or sell underlying securities. The Adviser expects that normally the Fund’s portfolio will tend to emphasize investments in larger capitalization companies, although the Fund may invest in smaller or medium capitalization companies. The Fund normally invests in approximately 90-130 companies.

The Fund may, at times, invest in shares of ETFs in lieu of making direct investments in securities. ETFs may provide more efficient and economical exposure to the types of companies and geographic locations in which the Fund seeks to invest than direct investments.

Currencies can have a dramatic impact on equity returns, significantly adding to returns in some years and greatly diminishing them in others. Currency and equity positions are evaluated separately. The Adviser may seek to hedge the currency exposure resulting from securities positions when it finds the currency exposure unattractive. To hedge all or a portion of its currency risk, the Fund may, from time to time, invest in currency-related derivatives, including forward currency exchange contracts, futures, options on futures, swaps and options. The Adviser may also seek investment opportunities by taking long or short positions in currencies through the use of currency-related derivatives.

The Fund may enter into other derivatives transactions, such as options, futures contracts, forwards, and swaps. The Fund may use options strategies involving the purchase and/or writing of various combinations of call and/or put options, including on individual securities and stock indexes, futures contracts (including futures contracts on individual securities and stock indexes) or shares of ETFs. These transactions may be used, for example, in an effort to earn extra income, to adjust exposure to individual securities or markets, or to protect all or a portion of the Fund’s portfolio from a decline in value, sometimes within certain ranges.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

MARKET RISK: The value of the Fund’s assets will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. It includes the risk that a particular style of investing, such as growth, may underperform the market generally.

FOREIGN (NON-U.S.) RISK: Investments in securities of non-U.S. issuers may involve more risk than those of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors.

EMERGING MARKET RISK: Investments in emerging market countries may have more risk because the markets are less developed and less liquid as well as being subject to increased economic, political, regulatory or other uncertainties.

CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Fund’s investments or reduce its returns.

CAPITALIZATION RISK: Investments in small- and mid-capitalization companies may be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies have limited product lines, markets or financial resources.

DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses for the Fund, and may be subject to counterparty risk to a greater degree than more traditional investments.

MANAGEMENT RISK: The Fund is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Fund, but there is no guarantee that its techniques will produce the intended results.

As with all investments, you may lose money by investing in the Fund.
