Portfolio Turnover [Text Block]

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 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. During the most recent fiscal year, the Fund's portfolio turnover rate was 122% of the average value of its portfolio.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

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. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund's Sub-Adviser seeks to achieve the Fund's investment objective by investing primarily in domestic, value-oriented, small-capitalization or "small cap" equity securities (common stock) of companies traded on U.S. stock exchanges or in the over-the-counter market using its fundamental stock selection process. Under normal market conditions, the Fund invests at least 80% of its assets (defined as net assets plus borrowing for investment purposes) in small cap companies. The Fund defines small capitalization companies as those companies whose market capitalizations are equal to or less than the largest company in the Russell 2000® Value Index during the most recent 12-month period. For the most recent annual reconstitution published as of June 30, 2015, the market capitalization range of companies in the Russell 2000® Value Index was approximately $103 million to $4.3 billion, which range will vary daily. Under general supervision of the Adviser, the Sub-Adviser seeks to fulfill the Fund's investment objective by using a quantitative stock ranking system combined with a qualitative risk review. The Sub-Adviser generally buys securities of small cap companies that are ranked highest by the model and pass the risk review. It generally sells securities when higher ranked or more compelling investments are identified. Although a "total return" investment objective typically entails both capital appreciation and income, the Fund emphasizes capital appreciation, but will capture some income through dividends and interest from cash investments.

The Fund may also engage in securities lending.

Risk [Heading]

Principal Investment Risks:

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with all mutual funds, there is the risk that you could lose money through your investment in the Fund. Although the Fund will strive to meet its investment objective, there is no assurance that it will do so. Many factors affect the Fund's net asset value and performance.

Liquidity Risk – Some securities may have few market-makers and low trading volume, which tend to increase transaction costs and may make it impossible for a Fund to dispose of a security position at all or at a price which represents current or fair market value.

Foreign Investing Risk –Investments in foreign countries are subject to currency risk and country-specific risks such as political, diplomatic, regional conflicts, terrorism, war, social and economic instability and policies that have the effect of decreasing the value of foreign securities. Foreign countries may be subject to different trading settlement practices, less government supervision, less publicly available information, limited trading markets and greater volatility than U.S. investments.

Management Risk – The Fund is subject to management risk because it is an actively managed investment portfolio. The Sub-Adviser's judgments about the attractiveness, "value" and potential appreciation of securities may prove to be inaccurate and may not produce the desired results. The Sub-Adviser will apply its investment techniques and risk analyses in making investment decisions for the Fund, but there is no guarantee that its decisions will produce the intended result. The successful use of hedging and risk management techniques may be adversely affected by imperfect correlation between movements in the price of the hedging vehicles and the securities being hedged.

Portfolio Turnover Risk – A higher portfolio turnover will result in higher transactional and brokerage costs and may result in higher taxes when Fund shares are held in a taxable account.

Securities Lending Risk – The risk of securities lending is that the financial institution that borrows securities from the Fund could go bankrupt or otherwise default on its commitment under the securities lending agreement and the Fund might not be able to recover the loaned securities or their value.

Small Capitalization Risk – The Fund's investments in small cap companies carry more risks than investments in larger companies. Small cap companies often have narrower markets, fewer products, or services to offer and more limited managerial and financial resources than do larger, more established companies.

Stock Market Risk – Stock markets can be volatile. In other words, the prices of stocks can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions. The Fund's investments may decline in value if the stock markets perform poorly.
